We are not aware of any independent, authoritative source of information regarding sizes, growth rates or market shares for most of our markets. Accordingly, the market size, market growth rate and market share estimates contained herein have been developed by us using internal and external sources and reflect our best current estimates. These estimates have not been confirmed by independent sources.

Percentages and certain amounts contained herein have been rounded for ease of presentation. Any discrepancies in any figure between totals and the sums of the amounts presented are due to rounding.

GLOSSARY

“assay values” Chemical result or mineral component amount contained by the sample.

“average global metallurgical recoveries” Percentage that measures the metallurgical treatment effectiveness based on the quantitative relationship between the initial product contained in the mine-extracted material and the final product produced in the plant.

“average mining exploitation factor” Index or ratio that measures the mineral exploitation effectiveness, based on the quantitative relationship between (in-situ mineral minus exploitation losses) / in-situ mineral.

“CAGR” Compound annual growth rate, the year over year growth rate of an investment over a specified period of time.

“cash and cash equivalents” The International Accounting Standards Board (IASB) defines cash and cash equivalents as short-term, highly liquid investments that are readily convertible to known amounts of cash and which are subject to an insignificant risk of changes in value.

“Controller Group” * A person or company or group of persons or companies that according to Chilean law, have executed a joint performance agreement, that have a direct or indirect share in a company’s ownership and have the power to influence the decisions of the company’s management.

“Corfo” Production Development Corporation (Corporación de Fomento de la Producción), formed in 1939, a national organization in charge of promoting Chile’s manufacturing productivity and commercial development.

iii

“CMF” The Chilean Commission for the Financial Market (La Comisión para el Mercado Financiero), formerly known as the Superintendence of Securities and Insurance (Superintendencia de Valores y Seguros or SVS).

“cut-off grade” The minimal assay value or chemical amount of some mineral component above which exploitation is economical.

“dilution” Loss of mineral grade because of contamination with barren material (or waste) incorporated in some exploited ore mineral.

“exploitation losses” Amounts of ore mineral that have not been extracted in accordance with exploitation designs.

“fertigation” The process by which plant nutrients are applied to the ground using an irrigation system.

“geostatistical analysis” Statistical tools applied to mining planning, geology and geochemical data that allow estimation of averages, grades and quantities of mineral resources and reserves.

“heap leaching” A process whereby minerals are leached from a heap, or pad, of ROM (run of mine) ore by leaching solutions percolating down through the heap and collected from a sloping, impermeable liner below the pad.

“horizontal layering” Rock mass (stratiform seam) with generally uniform thickness that conform to the sedimentary fields (mineralized and horizontal rock in these cases).

“hypothetical resources” Mineral resources that have limited geochemical reconnaissance, based mainly on geological data and samples assay values spaced between 500–1000 meters.

“Indicated Mineral Resource” See “Resources—Indicated Mineral Resource.”

“Inferred Mineral Resource” See “Resources—Inferred Mineral Resource.”

“industrial crops” Refers to crops that require processing after harvest in order to be ready for consumption or sale. Tobacco, tea and seed crops are examples of industrial crops.

“Kriging Method” A technique used to estimate ore reserves, in which the spatial distribution of continuous geophysical variables is estimated using control points where values are known.

“LIBOR” London Inter Bank Offered Rate.

“limited reconnaissance” Low or limited level of geological knowledge.

“Measured Mineral Resource” See “Resources—Measured Mineral Resource.”

“metallurgical treatment” A set of chemical and physical processes applied to the caliche ore and to the salar brines to extract their useful minerals (or metals).

“ore depth” Depth of the mineral that may be economically exploited.

“ore” A mineral or rock from which a substance having economic value may be extracted.

“Probable Mineral Reserve” See “Reserves—Probable Mineral Reserve.”

“Proven Mineral Reserve” See “Reserves—Proven Mineral Reserve.”

“Reserves—Probable Mineral Reserve” ** The economically mineable part of an Indicated Mineral Resource and, in some circumstances, Measured Mineral Resource. The calculation of the reserves includes diluting of materials and allowances for losses which may occur when the material is mined. Appropriate assessments, which may include feasibility studies, have been carried out and include consideration of and modification by realistically assumed mining, metallurgical, economic, marketing, legal, environmental, social and governmental factors. These assessments demonstrate at the time of reporting that extraction is reasonably justified. A Probable Mineral Reserve has a lower level of confidence than a Proven Mineral Reserve.

“Reserves—Proven Mineral Reserve” ** The economically mineable part of a Measured Mineral Resource. The calculation of the reserves includes diluting materials and allowances for losses which may occur when the material is mined. Appropriate assessments, which may include feasibility studies, have been carried out and include consideration of and modification by realistically assumed mining, metallurgical, economic, marketing, legal, environmental, social and governmental factors. These assessments demonstrate at the time of reporting that extraction is reasonably justified.

iv

“Resources—Indicated Mineral Resource” ** The part of a Mineral Resource for which tonnage, densities, shape, physical characteristics, grade and mineral content can be estimated with a reasonable level of confidence. The calculation is based on detailed exploration, sampling and testing information gathered through appropriate sampling techniques from locations such as outcrops, trenches and exploratory drill holes. The locations are too widely or inappropriately spaced to confirm geological continuity and/or grade continuity but are spaced closely enough for continuity to be assumed. An Indicated Mineral Resource has a lower level of confidence than that applying to a Measured Mineral Resource, but has a higher level of confidence than that applying to an Inferred Mineral Resource.

A deposit may be classified as an Indicated Mineral Resource when the nature, quality, amount and distribution of data are such as to allow the Competent Person, as that term is defined under Chilean Law Number 20,235, determining the Mineral Resource to confidently interpret the geological framework and to assume continuity of mineralization. Confidence in the estimate is sufficient to allow the appropriate application of technical and economic parameters and to enable an evaluation of economic viability.

“Resources—Inferred Mineral Resource” ** The part of a Mineral Resource for which tonnage, grade and mineral content can be estimated with a low level of confidence, by inferring them on the basis of geological evidence and assumed but not verified geological and/or grade continuity. The estimate is based on information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes, and this information is of limited or uncertain quality and/or reliability. An Inferred Mineral Resource has a lower level of confidence than that applying to an Indicated Mineral Resource.

“Resources—Measured Mineral Resource” ** The part of a Mineral Resource for which tonnage, densities, shape, physical characteristics, grade and mineral content can be estimated with a high level of confidence. The estimate is based on detailed exploration, sampling and testing information gathered through appropriate sampling techniques from locations such as outcrops, trenches and exploratory drill holes. The locations are spaced closely enough to confirm geological and/or grade continuity.

A deposit may be classified as a Measured Mineral Resource when the nature, quality, amount and distribution of data are such as to leave no reasonable doubt, in the opinion of the Competent Person, as that term is defined under Chilean Law Number 20,235, determining the Mineral Resource, that the tonnage and grade of the deposit can be estimated within close limits and that any variation from the estimate would not significantly affect potential economic viability. This category requires a high level of confidence in, and understanding of, the geology and controls of the mineral deposit. Confidence in the estimate is sufficient to allow the appropriate application of technical and economic parameters and to enable an evaluation of economic viability.

“Resources—Mineral Resource” ** A concentration or occurrence of natural, solid, inorganic or fossilized organic material in or on the Earth’s crust in such form or quantity and of such grade or quality that it has reasonable prospects for economically viable extraction. The location, quantity, grade, geological characteristics and continuity of a mineral resource are known, estimated or interpreted from specific geological, metallurgical and technological evidence.

“solar salts” A mixture of 60% sodium nitrate and 40% potassium nitrate used in the storage of thermo-energy.

“vat leaching” A process whereby minerals are extracted from crushed ore by placing the ore in large vats containing leaching solutions.

“waste” Rock or mineral which is not economical for metallurgical treatment.

“Weighted average age” The sum of the product of the age of each fixed asset at a given facility and its current gross book value as of December 31, 2017 divided by the total gross book value of the Company’s fixed assets at such facility as of December 31, 2017.

| * | The definition of a Controller Group that has been provided is the one that applies to the Company. Chilean law provides for a broader definition of a “controller group”, as such term is defined in Title XV of Chilean Law No. 18,045.

| ** | The definitions we use for resources and reserves are based on those provided by the “Instituto de Ingenieros de Minas de Chile” (Chilean Institute of Mining Engineers).

| (2) | Other income for 2013 includes US$84 million for the sale of royalties for the Antucoya mining project. After taxes, this sale had a one-time effect of US$67 million on profit for the year.

| (3) | Other expenses for 2014 includes provisions of approximately US$7 million corresponding to payments made in 2015 to the Chilean Internal Revenue Service (Servicio de Impuestos Internos or “SII”) for expenses that may not have qualified as tax expenses under the Chilean tax code. However, since such payments were made after March 3, 2015, the date on which the Company filed its statutory consolidated financial statements filed with the Chilean Comission for the Financial Market (La Comision para el Mercado Financiero or “CMF”), such provisions were included in net income for the period ended December 31, 2015 for purposes of the Company’s statutory consolidated financial statements. For more information, see “Item 3D. Risk Factors—Risks Relating to our Business—We could be subject to numerous risks in Chile as a result of investigations by the Chilean Public Prosecutor in relation to certain payments made by SQM between the tax years 2009 and 2015.”

| (5) | Other expenses for 2016 include a charge of US$32.8 million for impairment related to the closing of the train between Coya Sur and Tocopilla. Other expenses for 2016 also include charges of approximately US$30.5 million related to the Company's agreement with the U.S. Department of Justice and the administrative cease and desist order issued by the U.S. Securities and Exchange Commission in connection the inquiries arising out of the alleged violations of the books and records and internal controls provisions of the Foreign Corrupt Practices Act. For more information, see “Item 3D. Risk Factors—Risks Relating to our Business—We could be subject to numerous risks in Chile as a result of investigations by the Chilean Public Prosecutor in relation to certain payments made by SQM between the tax years 2009 and 2015” and “Item 8.A.7 Legal Proceedings.”

| (6) | Other expenses for 2017 include a charge of US$20.4 million relating to payment by our subsidiary SQM Salar S.A. to Corfo after entering into the Corfo Arbitration Agreement (as defined in “Risks Relating to our Business” section below) to terminate the arbitration proceedings and amend the existing Lease Agreement and Project Agreement (each as defined in “Risks Relating to our Business” section below). For more information, see “Item 8.A.7 Legal Proceedings.”

| (7) | In accordance with IAS 12, the effects generated by the change in the income tax rate approved by Law No. 20.780 on income and deferred taxes have been applied to the income statement. For purposes of the Company’s statutory consolidated financial statements filed with the CMF, in accordance with the instructions issued by the CMF in its circular 856 of October 17, 2014, the effects generated by the change in the income tax rate were accounted for as retained earnings. The amount charged to equity as of December 31, 2014 was US$52.3 million, thereby giving rise to a difference of US$52.3 million in profit and income tax expense in 2014 as presented in the Company’s Audited Consolidated Financial Statements compared with profit and income tax expense presented in the Company’s statutory consolidated financial statements filed with the CMF. The effects of subsequent changes in the income tax rate are recognized in profit or loss for the period in the Company’s statutory consolidated financial statements in accordance with IAS 12.

| (8) | The Company has not conducted any transaction that would give rise to a potential dilutive effect on its earnings per share in any of the indicated years. The total number of outstanding shares as of each period end is the same as the weighted average shares outstanding.

| (9) | The calculation of earnings per ADSs and dividends per ADS for the years indicated is based on the ratio of 1:1.

| (10) | Dividends per share are calculated based on 263,196,524 shares for each of the years indicated.

EXCHANGE RATES

Chile has two currency markets, the Formal Exchange Market (Mercado Cambiario Formal) in which we conduct our transactions, and the Informal Exchange Market (Mercado Cambiario Informal). The Formal Exchange Market comprises banks and other entities authorized by the Chilean Central Bank. The Informal Exchange Market comprises entities that are not expressly authorized to operate in the Formal Exchange Market, such as certain foreign exchange houses and travel agencies, among others. The Chilean Central Bank is empowered to determine that certain purchases and sales of foreign currencies be carried out on the Formal Exchange Market.

Both the Formal Exchange Market and the Informal Exchange Market are driven by free market forces. Current regulations require that the Chilean Central Bank be informed of certain transactions and that these transactions be effected through the Formal Exchange Market.

The Observed Exchange Rate (dólar observado), which is reported by the Chilean Central Bank and published daily in the Chilean newspapers, is computed by taking the weighted average of the previous business day’s transactions on the Formal Exchange Market. The Chilean Central Bank has the power to intervene by buying or selling foreign currency on the Formal Exchange Market to attempt to maintain the Observed Exchange Rate within a desired range. During the past few years the Chilean Central Bank has intervened to attempt to maintain the Observed Exchange Rate within a certain range only under special circumstances. Although the Chilean Central Bank is not required to purchase or sell U.S. dollars at any specific exchange rate, it generally uses spot rates for its transactions. Other banks generally carry out authorized transactions at spot rates as well.

The Informal Exchange Market reflects transactions carried out at an informal exchange rate (the “Informal Exchange Rate”). There are no limits imposed on the extent to which the Informal Exchange Rate can fluctuate above or below the Observed Exchange Rate. In recent years, the variations between the Observed Exchange Rate and the Informal Exchange Rate have not been significant.

The Federal Reserve Bank of New York does not report a noon buying rate for Chilean pesos.

The U.S. dollar is our functional currency. However, unless otherwise indicated, any amounts translated into U.S. dollars from Chilean pesos were translated using the Observed Exchange Rate for December 31, 2017, which was Ch$614.75 per US$1.00. As of April 18, 2018 the Observed Exchange Rate was US$1.00 per Ch$595.82.

Our operations are subject to certain risk factors that may affect SQM’s business, financial condition, cash flows, or results of operations. In addition to other information contained in this Annual Report on Form 20-F, you should carefully consider the risks described below. These risks are not the only ones we face. Additional risks not currently known to us or that are known but we currently believe are not significant may also affect our business operations. Our business, financial condition, cash flows or results of operations could be materially affected by any of these risks.

Risks Relating to our Business

We could be subject to numerous risks in Chile as a result of investigations by the Chilean Internal Revenue Service and the Chilean Public Prosecutor in relation to certain payments made by SQM between the tax years 2009 and 2015

The SII has conducted investigations related to the payment of invoices by SQM and its subsidiaries, SQM Salar S.A. (“SQM Salar”) and SQM Industrial S.A., for services that may not have been properly supported or that may not have been necessary to generate corporate income. The Chilean Public Prosecutor also has conducted related inquiries to determine whether such payments may be linked with alleged violations by SQM, these subsidiaries and public officials of political contribution or anti-corruption laws.

On February 26, 2015, SQM’s Board of Directors resolved to establish an ad-hoc committee of the Board of Directors (the “ad-hoc Committee”) authorized to conduct an internal investigation relating to the issues that were the subject of the SII and the Chilean Public Prosecutor investigations and to retain such independent external advice as it deemed appropriate. The original members of the ad-hoc Committee were former Board members José María Eyzaguirre B., Juan Antonio Guzmán M. and Wolf von Appen B.

The ad-hoc Committee engaged its own lawyers from Chile and the U.S. and forensic accountants from the U.S. to assist with its internal review. The U.S. lawyers retained by the ad-hoc Committee were principally charged with reviewing the relevant facts and analyzing those facts against the requirements of the U.S. Foreign Corrupt Practices Act (FCPA). The factual findings of the ad-hoc Committee, however, were ultimately shared with Chilean as well as U.S. authorities.

On March 12, 2015, José María Eyzaguirre B. resigned from the ad-hoc Committee and his position was subsequently filled by former Board member Hernán Büchi B.

On March 16, 2015, the Board of Directors decided to terminate the employment contract of the Company’s then- CEO, Patricio Contesse G. This followed his failure to cooperate with the ad-hoc Committee’s investigation.

On March 17, 2015, three members of the Board of Directors resigned, all of whom had been nominated by Potash Corporation of Saskatchewan Inc. (“PCS”), which was one of SQM’s two principal shareholder groups at such time. PCS merged with Agrium Inc. on January 1, 2018, forming Nutrien Ltd. (“Nutrien”), which is currently the owner of 32% of the total outstanding shares of SQM. PCS issued a press release stating that the directors resigned because of their concern that they could not ensure that the Company was conducting an appropriate investigation and collaborating effectively with the Chilean Public Prosecutor.

On March 20, 2015, the Company identified to the SII approximately US$11 million in payments of invoices that may not have been properly supported by services rendered or that may not qualify as tax expenses under the Chilean tax code. These payments originated from the office of the former CEO, Patricio Contesse G., during the six-year tax period from 2009 to 2014. As a result, the Company subsequently submitted amendments to its tax returns for the 2009 to 2014 tax years and thereafter paid taxes and interest relating to such amended returns totaling approximately US$7 million. On April 24, 2015, the Company announced that it had identified up to an additional US$2 million in payments by its subsidiary SQM Salar during the same six-year tax period that were also authorized by the former CEO and that may be deemed not properly supported by services rendered or that may not qualify as tax expenses under the Chilean tax code. Subsequently, SQM Salar filed amended tax returns and paid taxes and interest relating to such amended returns totaling approximately US$1.2 million. On August 14, 2015, the Company announced that it had identified to the SII approximately US$1.6 million in additional payments by SQM S.A. and its subsidiary SQM Industrial S.A. that may be deemed not properly supported by services rendered or that may not qualify as tax expenses under the Chilean tax code. SQM S.A. and SQM Industrial S.A. subsequently filed amended tax returns and, in early 2016, SQM Industrial S.A. paid taxes and interest relating to such amended returns totaling approximately US$0.3 million, and SQM S.A. paid taxes and interest relating to such amended returns totaling approximately US$1.3 million. The statute of limitations under Chilean law for tax claims is up to six years, during which period the former CEO had an annual discretionary budget covering the Company and its subsidiaries of approximately US$6 million.

On March 23, 2015, the SII, based on the Income Tax Law (Ley de Impuesto a La Renta), filed a criminal claim against the Company’s former CEO and the current CEO and CFO in their capacities as the Company’s tax representatives relating to part of the payments referred to above. This and subsequent related similar claims filed by the SII against these officers and third parties are currently under review by the Chilean Public Prosecutor.

On March 31, 2015, the CMF filed an administrative claim against five then-current and former members of the Board of Directors, alleging that they did not release information in a timely manner relating to the payments that are subject to the tax claim referred to above. On September 30, 2015, the CMF proceeded to fine them UF1,000 each (approximately US$36,000). They are currently appealing this decision to the Chilean courts.

On April 24, 2015, new members were elected to the Board of Directors at the Annual General Shareholders’ Meeting, including three new members that were nominated by PCS, and the ad-hoc Committee was subsequently reconstituted by Board of Directors members Robert A. Kirkpatrick, Wolf von Appen B. and Edward J. Waitzer.

On April 30, 2015, the Chilean Public Prosecutor, after reviewing the claims filed by the SII, informed the Company’s former CEO that it was formally investigating allegations that he approved the payment of invoices that may not be properly supported by services rendered or that may not qualify as tax expenses under the Chilean tax code and in connection therewith made intentionally false or incomplete declarations or used fraudulent procedures designed to conceal or disguise the true amount of transactions or to circumvent taxes. If he is finally adjudicated responsible, the Company may also be subject to the payment of a fine by the Chilean Criminal Court totaling 50% to 300% of the taxes paid. The Company estimates that no provision is needed at this stage.

On May 11, 2015, the SII filed an additional criminal claim against the former CEO and the current CEO and CFO in their capacities as the Company’s tax representatives alleging violations of the Chilean Inheritance and Donations Law (Ley sobre Impuesto a Las Herencias, Asignaciones y Donaciones). The claim states that the Company paid two invoices in 2009 and 2010 totaling approximately US$175,000 that are alleged to have been improperly supported. The claim states that these payments should have been classified as donations, and appropriate taxes should have been paid. These payments were accounted for in the amended tax returns filed with the SII. Subsequently, the SII filed a number of additional claims against these officers and third parties alleging violations of Chilean tax law and the Chilean Inheritance and Donations Law. The most recent of these criminal claims was filed by the SII on March 9, 2016. All of these claims are under review by the Chilean Public Prosecutor.

On September 29, 2015, the Company was notified of a labor lawsuit by its former CEO, Patricio Contesse, claiming payment from the Company related to the termination of his employment contract. The total amount claimed in the lawsuit is approximately Ch$4.0 billion (approximately US$5.7 million), including severance payments for years of service and other legal or contractual payments. The lower court held that Mr. Contesse’s claim was barred by the statute of limitations. On November 8, 2016, the Santiago Court of Appeals overruled the lower court decision. On March 27, 2017, the Company reached an agreement with Mr. Contesse to terminate the labor lawsuit Mr. Contesse filed against the Company. The amount included in the agreement was provisioned for in the financial statements as of December 31, 2016.

On October 14, 2015, two class action complaints then pending against the Company, our former CEO and current CEO and CFO, alleging violations of the U.S. securities laws in connection with the subject matter of the investigations described above, were consolidated into a single action in the United States District Court for the Southern District of New York. On November, 13, 2015, our former CEO and current CEO and CFO were voluntarily dismissed from the case without prejudice. On January 15, 2016, the lead plaintiff filed a consolidated class action complaint exclusively against the Company. On January 10, 2018, the lead plaintiff filed a motion to certify a class consisting of all persons who purchased SQM ADSs between June 30, 2010 and March 18, 2015. For more information on the consolidated class action, see “Item 8.A.7 Legal Proceedings.”

During 2015, the ad-hoc Committee that was established in February 15, 2015, conducted an investigation into whether the Company faced possible liability under the FCPA. The ad-hoc Committee engaged its own separate counsel, Shearman & Sterling LLP, which presented a report to the Board of Directors on December 15, 2015.

Following the presentation by the ad-hoc Committee of its findings to the Board of Directors, the Company voluntarily shared the findings of the ad-hoc Committee investigation with authorities in Chile and the U.S. (including the U.S. Securities and Exchange Commission (“SEC”) and the U.S. Department of Justice (“DOJ”)).

On January 13, 2017, the Company and the DOJ reached agreement on the terms of a Deferred Prosecution Agreement (“DPA”) that would resolve the DOJ’s inquiry, based on alleged violations of the books and records and internal controls provisions of the Foreign Corrupt Practices Act. Among other terms, the DPA called for the Company to pay a monetary penalty of US$15,487,500, and engage a compliance monitor for a term of two (2) years. Upon successful completion of the three (3) year term of the DPA, all charges against the Company will be dismissed. On the same date, the SEC agreed to resolve its inquiry through an administrative cease and desist order, arising out of the alleged violations of the same accounting provisions of the FCPA. Among other terms, the SEC order called for the Company to pay an additional monetary penalty of US$15 million. These penalties were reflected in the 2016 financial statements.

On January 26, 2018, the 8th Court of Santiago approved a deferred prosecution agreement proposed by the Chilean Public Prosecutor relating to SQM and its subsidiaries SQM Salar and SQM Nitratos S.A., to suspend an investigation against these entities related to potential corruption issues and responsibility for the lack of supervision and management. Under the deferred prosecution agreement, SQM, SQM Salar and SQM Nitratos S.A., have not admitted responsibility in the matter subject to the investigation but agreed to pay an aggregate amount of (i) Ch$900,000,000 to the Chilean government, and (ii) Ch$1,650,000,000 to various charitable organizations. As of January 26, 2018, these amounts were equivalent to approximately US$1.5 million and US$2.8 million, respectively, and were accrued in the Consolidated Financial Statements of the Company for 2017. In addition, the companies have agreed to provide the Chilean Public Prosecutor with a report on the enhancements to their compliance program, implemented in recent years, with special emphasis on the incorporation of best practices in various jurisdictions. See “Item 8.A.7 Legal Proceedings.”

In the event that the applicable regulatory authorities believe that the terms of the DPA or the deferred prosecution agreement with the Chilean Public Prosecutor are not complied with, it is possible that such regulatory authorities may reinstate the suspended proceedings against us and may bring further action against us, including in the form of additional inquiries or legal proceedings. Responding to our regulators’ inquiries and any future civil, criminal or regulatory inquiries or proceedings diverts our management’s attention from day-to-day operations. Additionally, expenses that may arise from responding to such inquiries or proceedings, our review of responsive materials, any related litigation or other associated activities may continue to be significant. Current and former employees, officers and directors may seek indemnification, advancement or reimbursement of expenses from us, including attorneys’ fees, with respect to the current inquiry or future proceedings related to this matter. The occurrence of any of the foregoing or adverse determination in litigation or other proceedings or similar actions could materially and adversely affect our business, financial condition, cash flows, results of operations and the prices of our securities.

The failure to amend the Lease Agreement and the Project Agreement relating to the Salar de Atacama concession could have a material adverse effect on our business, financial condition and results of operations

Our subsidiary SQM Salar S.A. (“SQM Salar”), as leaseholder, holds exclusive and temporary rights over the mineral resources in an area covering approximately 140,000 hectares of land in the Salar de Atacama in northern Chile, of which SQM Salar is entitled to exploit the mineral resources in 81,920 hectares. These rights are owned by Corfo and leased to SQM Salar pursuant to (i) a 1993 lease agreement over mining exploitation concessions between SQM Salar and Corfo, a Chilean government entity (the “Lease Agreement”), and (ii) the Salar de Atacama project agreement between Corfo and SQM Salar (the “Project Agreement”). Corfo may not unilaterally amend the Lease Agreement or the Project Agreement. The Lease Agreement establishes that SQM Salar is responsible for making quarterly lease payments to Corfo, maintaining Corfo’s rights over the mining exploitation concessions, and making annual payments to the Chilean government for such concession rights. The Lease Agreement expires on December 31, 2030. Furthermore, under the regulations of the Chilean Nuclear Energy Commission (Comisión Chilena de Energía Nuclear or “CCHEN”), we were limited to 180,100 tons of total lithium metallic equivalent (958,672 tons of lithium carbonate equivalent) extraction in the aggregate for all periods. For the year ended December 31, 2017, revenues related to products originating from the Salar de Atacama represented 47% of our consolidated revenues, consisting of revenues from our potassium business line and our lithium and derivatives business line for the period. All of our products originating from the Salar de Atacama are derived from our extraction operations under the Lease Agreement. As of December 31, 2017, only 13 years remain on the term of the Lease Agreement and we had extracted approximately 64% of the total permitted accumulated extraction and sales limit of lithium.

On January 17, 2018, Corfo and our subsidiaries SQM Potasio S.A. and SQM Salar reached an agreement (the “Corfo Arbitration Agreement”) to (i) terminate the previously disclosed arbitration proceedings between Corfo and SQM Salar, which, among other things, sought early termination of the Lease Agreement and (ii) amend the Lease Agreement and the Project Agreement. As part of the agreement to amend the Lease Agreement, Corfo authorized an increase of the production and sales of lithium products produced in the Salar de Atacama up to 349,553 metric tons of lithium metallic equivalent (1,860,670 tons of lithium carbonate equivalent), which is in addition to the approximately 64,816 metric tons of lithium metallic equivalent (345,015 tons of lithium carbonate equivalent) remaining from the originally authorized amount. The amendments of the Lease Agreement and the Project Agreement required under Chilean Law the issuance of the applicable resolutions of the Office of the Comptroller General of the Republic (Contraloría General de la República) and the CCHEN.

On February 15, 2018 and February 16, 2018, the Atacamenos Indigenous Organization (Consejo de Pueblos Atacamenos) initiated legal actions challenging the amendments of the Lease Agreement and the Project Agreement. The legal actions are pending before the Santiago Court of Appeals. See “Item 8.A.7 Legal Proceedings.”

| 8 |

On March 8, 2018, the CCHEN published its authorization for the increase in the quota of the amount of lithium that may be extracted from the Salar de Atacama concession for all periods for which there are increases under the proposed Lease Agreement amendment with Corfo. In addition, the authorization by the CCHEN provides that the amendments to the Lease Agreement and the Project Agreement may be revoked if any person or entity acquires control or a significant influence (influencia decisiva) over SQM without prior antitrust approval. SQM has challenged the CCHEN authorization with the objective of eliminating such provision. SQM believes that its challenge will not affect the validity of the Corfo Arbitration Agreement or the amendments to the Lease Agreement or the Project Agreement. However, there can be no assurance that SQM will prevail in eliminating such provision and in the event such provision is not eliminated, there could be no assurance that the amendments to the Lease Agreement and the Project Agreement will not be revoked upon violation of such provisions. In addition, the adoption of the CCHEN authorization is currently being challenged by the Atacamenos Indigenous Organization (Consejo de Pueblos Atacamenos), which challenge, if successful, may result in the revocation of CCHEN authorization.

On April 10, 2018, the Office of the Comptroller General of the Republic (Contraloría General de la República) issued a resolution approving the amendments of the Lease Agreement and the Project Agreement.

In addition, in connection with the Corfo Arbitration Agreement, on December 18, 2017, the companies that are part of the Pampa Group entered into an agreement for the benefit of Corfo (the “Pampa Group Agreement”), which, among other things, provides for: (i) the termination of the Joint Operation Agreement, and (ii) an agreement to not enter into any joint action with third parties that allows Pampa Group to acquire the status of sole controller or joint controller, as defined by article 97 of the Chilean Securities Market Law. The obligations set forth in clause (ii) expire on December 31, 2030. In addition, the Pampa Group Agreement also includes numerous provisions relating to corporate governance and control. The effectiveness of the obligations of the parties to the Pampa Group Agreement is subject to the execution of the amendments of the Lease Agreement and the Project Agreement and the obtainment of all approvals under Chilean Law. See “Item 8.A.7 Legal Proceedings.” Neither SQM nor any of its subsidiaries, including SQM Potasio S.A. and SQM Salar, is a party to the Pampa Group Agreement.

In the event the Lease Agreement is not amended as contemplated by the Corfo Arbitration Agreement, or the CCHEN authorization for the increased extraction is revoked according to its terms, there can be no assurance that we will not reach the lithium extraction limit referred to above prior to the expiration of the term of the Lease Agreement. In such event, we would then be unable to continue extraction of lithium under the Lease Agreement, which could have a material adverse effect on our business, financial condition and results of operations.

Our market reputation, commercial dealings or the price of our securities could be adversely affected by the negative outcome of certain proceedings against certain former members of our Board and certain other named defendants

On September 10, 2013, the CMF issued a press release disclosing it had instituted certain administrative proceedings (the “Cascading Companies Proceedings”) against (i) Julio Ponce Lerou (who was the Chairman of the Board and a director of the Company until April 24, 2015), (ii) Patricio Contesse Fica, who was a director of the Company until April 24, 2015 and is the son of Patricio Contesse González (who was the Company’s CEO until March 16, 2015), and (iii) other named defendants. The Company has been informed that Mr. Ponce and persons related to him beneficially owned 29.97% of SQM’s total shares as of December 31, 2017. See “Item 6.E. Share Ownership.” The CMF alleged breaches of Chilean corporate and securities laws in connection with acts performed by entities with direct or indirect share ownership interests in SQM (the “Cascading Companies”). The allegations made in connection with the Cascading Companies Proceedings do not relate to the Company’s operations, nor do they relate to any acts or omissions of the Company or any of its directors, officers or employees in their capacities as such.

In connection with the Cascading Companies Proceedings, the CMF alleged the existence of a scheme involving the named defendants whereby, through a number of transactions occurring between 2009 and 2011, the Cascading Companies allegedly sold securities of various companies, including securities of SQM, at below-market prices to companies related to Mr. Ponce and other named defendants. These companies allegedly subsequently sold such securities after a lapse of time, in most cases back to the Cascading Companies, at prices higher than the purchase price. The CMF alleged violations by the defendants of a number of Chilean corporate and securities laws in furtherance of the alleged scheme.

| 9 |

On January 31, 2014, the CMF added a number of Chilean financial institutions and asset managers, and certain of their controlling persons, executives or other principals, as named defendants to the Cascading Companies Proceedings. On September 2, 2014, the CMF issued a decision imposing an aggregate fine against all of the defendants of UF 4.0 million (approximately US$174 million as of December 31, 2017), including a fine against Mr. Ponce of UF 1.7 million (approximately US$74 million as of December 31, 2017) and a fine against Mr. Contesse Fica of UF 60,000 (approximately US$2.6 million as of December 31, 2017). The defendants are currently challenging the CMF administrative decision before Chilean courts.

The High Complexity Crimes Unit (Unidad de Delitos de Alta Complejidad) of the Metropolitan District Central Northern Attorney’s Office (Fiscalía Metropolitana Centro Norte) is also investigating various criminal complaints filed against various parties to the Cascading Companies Proceedings. The SII requested payment of taxes by the Cascading Companies, and the Cascading Companies filed a complaint with the tax courts.

If, for any reason, the Company is unable to differentiate itself from the named defendants, such failure could have a material adverse effect on the Company’s market reputation and commercial dealings. Furthermore, we cannot assure you that a non-appealable ruling in connection with the Cascading Companies Proceedings or the investigations of the High Complexity Crimes Unit or the SII that is adverse to Mr. Ponce or Mr. Contesse Fica will not have a material adverse effect on our market reputation, commercial dealings and the price of our securities, or that the Cascading Companies will not sell shares of the Company or vote to increase the dividends we pay to our shareholders.

We identified a material weakness in our internal controls over payments directed by the office of the former Chief Executive Officer

In the past, our management determined that the Company did not maintain effective control over payments directed by the office of the former CEO. This determination was reported in our annual report for the year ended December 31, 2014 on Form 20-F, filed with the SEC on May 18, 2015.

We believe we have taken the necessary steps to remediate the identified material weakness and enhance our internal controls. However, any failure to maintain effective internal control over financial reporting could (i) result in a material misstatement in our financial reporting or financial statements that would not be prevented or detected, (ii) cause us to fail to meet our reporting obligations under applicable securities laws or (iii) cause investors to lose confidence in our financial reporting or financial statements, the occurrence of any of which could materially and adversely affect our business, financial condition, cash flows, results of operations and the prices of our securities.

Volatility of world fertilizer and chemical prices and changes in production capacities could affect our business, financial condition and results of operations

The prices of our products are determined principally by world prices, which, in some cases, have been subject to substantial volatility in recent years. World fertilizer and chemical prices vary depending upon the relationship between supply and demand at any given time. Supply and demand dynamics for our products are tied to a certain extent to global economic cycles, and have been impacted by circumstances related to such cycles. Furthermore, the supply of certain fertilizers or chemical products, including certain products that we provide, varies principally depending on the production of the major producers, (including us) and their respective business strategies.

World prices of potassium-based fertilizers (including some of our specialty plant nutrients and potassium chloride) fluctuated as a result of the broader global economic and financial conditions. During the second half of 2013, potassium prices declined as a result of an unexpected announcement made by the Russian company Uralkali (“Uralkali”) that it was terminating its participation in Belarus Potash Corporation (“BPC”). As a result of the termination of Uralkali’s participation in BPC, there was increased price competition in the market. The average price for our potassium chloride and potassium sulfate business line was approximately 7% higher in 2017 compared to 2016. Our sales volumes for this business line were approximately 12% lower in 2017 compared to 2016. We cannot assure you that potassium-based fertilizer prices and sales volumes will not decline in the future.

Iodine prices followed an upward trend beginning at the end of 2008 and continuing through 2012, reaching an average price of approximately US$53 per kilogram in 2012, over 40% higher than average prices in 2011. During the following years, supply growth outpaced demand growth, causing a decline in iodine prices. We obtained an average price for iodine of approximately US$20 per kilogram in 2017, approximately 12% less than average prices obtained in 2016. We cannot assure you that iodine prices or sales volumes will not continue to decline in the future.

Driven mostly by an increase in demand related to battery use, lithium demand growth in 2016 was accompanied by an increase in supply that was lower than expected, and as a result, average prices for this business line increased approximately 80% compared to 2015. In 2017, lithium demand continued to grow creating tight market conditions and increasing prices by 25% compared to 2016. We cannot assure you that lithium prices and sales volumes will not decline in the future.

We expect that prices for the products we manufacture will continue to be influenced, among other things, by worldwide supply and demand and the business strategies of major producers. Some of the major producers (including us) have increased or have the ability to increase production. As a result, the prices of our products may be subject to substantial volatility. High volatility or a substantial decline in the prices or sales volumes of one or more of our products could have a material adverse effect on our business, financial condition and results of operations.

Our sales to emerging markets and expansion strategy expose us to risks related to economic conditions and trends in those countries

We sell our products in more than 110 countries around the world. In 2017, approximately 42% of our sales were made in emerging market countries: 11% in Latin America (excluding Chile); 9% in Africa and the Middle East (excluding Israel); 7% in Chile and 15% in Asia and Oceania (excluding Australia, Japan, New Zealand, South Korea and Singapore). We expect to expand our sales in these and other emerging markets in the future. In addition, we may carry out acquisitions or joint ventures in jurisdictions in which we currently do not operate, relating to any of our businesses or to new businesses in which we believe we may have sustainable competitive advantages. The results of our operations and our prospects in other countries in which we establish operations will depend, in part, on the general level of political stability and economic activity and policies in those countries. Future developments in the political systems or economies of these countries or the implementation of future governmental policies in those countries, including the imposition of withholding and other taxes, restrictions on the payment of dividends or repatriation of capital, the imposition of import duties or other restrictions, the imposition of new environmental regulations or price controls or changes in relevant laws or regulations, could have a material adverse effect on our business, financial condition and results of operations in those countries.

Our inventory levels may increase for economic or operational reasons

In general, economic conditions or operational factors can affect our inventory levels. Higher inventories carry a financial risk due to increased need for cash to fund working capital and could imply increased risk of loss of product. We cannot assure you that inventory levels will not continue to remain high or increase further in the future. These factors could have a material adverse effect on our business, financial condition and results of operations.

Our measures to minimize our exposure to bad debt may not be effective and a significant increase in our accounts receivable coupled with the financial condition of customers may result in losses that could have a material adverse effect on our business, financial condition and results of operations

Potentially negative effects of global economic conditions on the financial condition of our customers may include the extension of the payment terms of our accounts receivable and may increase our exposure to bad debt. While we have implemented certain safeguards, such as using credit insurance, letters of credit and prepayment for a portion of sales, to minimize the risk, we cannot assure you that such safeguards will be effective and a significant increase in our accounts receivable coupled with the financial condition of customers may result in losses that could have a material adverse effect on our business, financial condition and results of operations.

New production of iodine or lithium carbonate from current or new competitors in the markets in which we operate could adversely affect prices

In recent years, new and existing competitors have increased the supply of iodine and lithium carbonate, which has affected prices for both products. Further production increases could negatively impact prices. There is limited information on the status of new iodine or lithium carbonate production capacity expansion projects being developed by current and potential competitors and, as such, we cannot make accurate projections regarding the capacities of possible new entrants into the market and the dates on which they could become operational. If these potential projects are completed in the short term, they could adversely affect market prices and our market share, which, in turn, could have a material adverse effect on our business, financial condition and results of operations.

We have a capital expenditure program that is subject to significant risks and uncertainties

Our business is capital intensive. Specifically, the exploration and exploitation of reserves, mining and processing costs, the maintenance of machinery and equipment and compliance with applicable laws and regulations require substantial capital expenditures. We must continue to invest capital to maintain or to increase our exploitation levels and the amount of finished products we produce.

In addition, we require environmental permits for our new projects. Obtaining permits in certain cases may cause significant delays in the execution and implementation of new projects and, consequently, may require us to reassess the related risks and economic incentives. We cannot assure you that we will be able to maintain our production levels or generate sufficient cash flow, or that we will have access to sufficient investments, loans or other financing alternatives, to continue our activities at or above present levels, or that we will be able to implement our projects or receive the necessary permits required for them in time. Any or all of these factors may have a material adverse effect on our business, financial condition and results of operations.

High raw materials and energy prices could increase our production costs and cost of sales, and energy may become unavailable at any price

We rely on certain raw materials and various energy sources (diesel, electricity, liquefied natural gas, fuel oil and others) to manufacture our products. Purchases of energy and raw materials we do not produce constitute an important part of our cost of sales, approximately 14% in 2017. In addition, we may not be able to obtain energy at any price if supplies are curtailed or otherwise become unavailable. To the extent we are unable to pass on increases in the prices of energy and raw materials to our customers or we are unable to obtain energy, our business, financial condition and results of operations could be materially adversely affected.

| 12 |

Our reserves estimates are internally prepared and not subject to review by external geologists or an external auditing firm and could be subject to significant changes, which may have a material adverse effect on our business, financial condition and results of operations

Our caliche ore mining reserves estimates and our Salar de Atacama brine mining reserve estimates are prepared by our own geologists and hydrogeologists and are not subject to review by external geologists or an external auditing firm. Estimation methods involve numerous uncertainties as to the quantity and quality of the reserves, and reserve estimates could change upwards or downwards. A downward change in the quantity and/or quality of our reserves could affect future volumes and costs of production and therefore have a material adverse effect on our business, financial condition and results of operations.

Quality standards in markets in which we sell our products could become stricter over time

In the markets in which we do business, customers may impose quality standards on our products and/or governments may enact stricter regulations for the distribution and/or use of our products. As a result, if we cannot meet such new standards or regulations, we may not be able to sell our products. In addition, our cost of production may increase in order to meet any such newly imposed or enacted standards or regulations. Failure to sell our products in one or more markets or to important customers could materially adversely affect our business, financial condition and results of operations.

Chemical and physical properties of our products could adversely affect their commercialization

Since our products are derived from natural resources, they contain inorganic impurities that may not meet certain customer or government standards. As a result, we may not be able to sell our products if we cannot meet such requirements. In addition, our cost of production may increase in order to meet such standards. Failure to meet such standards could materially adversely affect our business, financial condition and results of operations if we are unable to sell our products in one or more markets or to important customers in such markets.

Our business is subject to many operating and other risks for which we may not be fully covered under our insurance policies

Our facilities and business operations in Chile and abroad are insured against losses, damage or other risks by insurance policies that are standard for the industry and that would reasonably be expected to be sufficient by prudent and experienced persons engaged in businesses similar to ours.

We may be subject to certain events that may not be covered under our insurance policies, which could have a material adverse effect on our business, financial condition and results of operations. Additionally, as a result of major earthquakes and unexpected rains and flooding in Chile, as well as other natural disasters worldwide, conditions in the insurance market have changed and may continue to change in the future, and as a result, we may face higher premiums and reduced coverage, which could have a material adverse effect on our business, financial condition and results of operations.

Changes in technology or other developments could result in preferences for substitute products

Our products, particularly iodine, lithium and their derivatives, are preferred raw materials for certain industrial applications, such as rechargeable batteries and liquid-crystal displays (LCDs). Changes in technology, the development of substitute raw materials or other developments could adversely affect demand for these and other products which we produce. In addition, other alternatives to our products may become more economically attractive as global commodity prices shift. Any of these events could have a material adverse effect on our business, financial condition and results of operations.

| 13 |

We are exposed to labor strikes and labor liabilities that could impact our production levels and costs

Over 95% of our employees are employed in Chile, of which approximately 64% were represented by 22 labor unions as of December 31, 2017. As of July 31, 2017 we renegotiated collective labor contracts with three unions. As a result, all collective labor contracts were renegotiated for the next three years as of that date. From November 2017, we started a new cycle of the individual labor contract negotiations. We are exposed to labor strikes and illegal work stoppages that could impact our production levels. If a strike or illegal work stoppage occurs and continues for a sustained period of time, we could be faced with increased costs and even disruption in our product flow that could have a material adverse effect on our business, financial condition and results of operations.

Chilean Law No. 20,123, known as the Subcontracting Law, provides that when a serious workplace accident occurs, the company in charge of the workplace must halt work at the site where the accident took place until authorities from either the National Geology and Mining Service (Servicio Nacional de Geología y Minería or “Sernageomin”), the Labor Board (Dirección del Trabajo or “Labor Board”), or the National Health Service (Servicio Nacional de Salud), inspect the site and prescribe the measures such company must take to minimize the risk of similar accidents taking place in the future. Work may not be resumed until the applicable company has taken the prescribed measures, and the period of time before work may be resumed may last for a number of hours, days, or longer. The effects of this law could have a material adverse effect on our business, financial condition and results of operations.

On September 8, 2016, Chilean Law No. 20,940 was published and modified the Labor Code by introducing, among other things, changes to the formation of trade unions, the election of inter-company union delegates, the presence of women on union boards, anti-union practices and related sanctions, and collective negotiations. Due to these changes to the labor regulations, we may face an increase in our expenses that may have a significant adverse effect on our business, financial condition, and results of operations.

Lawsuits and arbitrations could adversely impact us

We are party to a range of lawsuits and arbitrations involving different matters as described in Note 19.1 of our Consolidated Financial Statements and “Item 8.A. Legal Proceedings.” Although we intend to defend our positions vigorously, our defense of these actions may not be successful and responding to such lawsuits and arbitrations diverts our management’s attention from day-to-day operations. Adverse judgments or settlements in these lawsuits may have a material adverse effect on our business, financial condition and results of operations. In addition, our strategy of being a world leader includes entering into commercial and production alliances, joint ventures and acquisitions to improve our global competitive position. As these operations increase in complexity and are carried out in different jurisdictions, we may be subject to legal proceedings that, if settled against us, could have a material adverse effect on our business, financial condition and results of operations.

We have operations in multiple jurisdictions with differing regulatory, tax and other regimes

We operate in multiple jurisdictions with complex regulatory environments that are subject to different interpretations by companies and respective governmental authorities. These jurisdictions may have different tax codes, environmental regulations, labor codes and legal framework, which adds complexity to our compliance with these regulations. Any failure to comply with such regulations could have a material adverse effect on our business, financial condition and results of operations.

| 14 |

Environmental laws and regulations could expose us to higher costs, liabilities, claims and failure to meet current and future production targets

Our operations in Chile are subject to national and local regulations relating to environmental protection. In accordance with such regulations, we are required to conduct environmental impact studies or statements before we conduct any new projects or activities or significant modifications of existing projects that could impact the environment or the health of people in the surrounding areas. We are also required to obtain an environmental license for certain projects and activities. The Environmental Evaluation Service (Servicio de Evaluación Ambiental or “Environmental Evaluation Service”) evaluates environmental impact studies submitted for its approval. The public, government agencies or local authorities may review and challenge projects that may adversely affect the environment, either before these projects are executed or once they are operating, if they fail to comply with applicable regulations. In order to ensure compliance with environmental regulations, Chilean authorities may impose fines up to approximately US$9 million per infraction, revoke environmental permits or temporarily or permanently close facilities, among other enforcement measures.

Chilean environmental regulations have become increasingly stringent in recent years, both with respect to the approval of new projects and in connection with the implementation and development of projects already approved, and we believe that this trend is likely to continue. Given public interest in environmental enforcement matters, these regulations or their application may also be subject to political considerations that are beyond our control.

We regularly monitor the impact of our operations on the environment and on the health of people in the surrounding areas and have, from time to time, made modifications to our facilities to minimize any adverse impact. Future developments in the creation or implementation of environmental requirements or their interpretation could result in substantially increased capital, operation or compliance costs or otherwise adversely affect our business, financial condition and results of operations.

The success of our current investments at the Salar de Atacama and Nueva Victoria is dependent on the behavior of the ecosystem variables being monitored over time. If the behavior of these variables in future years does not meet environmental requirements, our operation may be subject to important restrictions by the authorities on the maximum allowable amounts of brine and water extraction. For example, on December 13, 2017, the First Environmental Court of Antofagasta ordered the temporary and partial closure of certain water extraction wells located in the Salar de Llamara. These wells allow the Company to extract approximately 124 liters per second of water, almost 15% of the water used in the Company´s operations in the First Region of Chile for iodine and nitrate production.

Our future development depends on our ability to sustain future production levels, which requires additional investments and the submission of the corresponding environmental impact studies or statements. If we fail to obtain approval or required environmental licenses, our ability to maintain production at specified levels will be seriously impaired, thus having a material adverse effect on our business, financial condition and results of operations.

In addition, our worldwide operations are subject to international and other local environmental regulations. Since environmental laws and regulations in the different jurisdictions in which we operate may change, we cannot guarantee that future environmental laws, or changes to existing environmental laws, will not materially adversely impact our business, financial condition and results of operations.

Our water supply could be affected by geological changes or climate change

Our access to water may be impacted by changes in geology, climate change or other natural factors, such as wells drying up or reductions in the amount of water available in the wells or rivers from which we obtain water, that we cannot control. Any such change may have a material adverse effect on our business, financial condition and results of operations.

Any loss of key personnel may materially and adversely affect our business

Our success depends in large part on the skills, experience and efforts of our senior management team and other key personnel. The loss of the services of key members of our senior management or employees with critical skills could have a negative effect on our business, financial condition and results of operations. If we are not able to attract or retain highly skilled, talented and qualified senior managers or other key personnel, our ability to fully implement our business objectives may be materially and adversely affected.

| 15 |

A significant percentage of our shares are held by two principal shareholder groups who may have an interest that is different from that of other shareholders and of each other. Any change in such principal shareholder groups may result in a change of control of the Company or of its Board of Directors or its management, which may have a material adverse effect on our business, financial condition and results of operations

As of February 7, 2018, two principal shareholder groups held in the aggregate 64.08% of the total outstanding shares of SQM, including a majority of our Series A common shares, and have the power to elect seven of our eight directors. The interests of the two principal shareholder groups may in some cases differ from those of other shareholders and of each other.

One of the principal shareholder groups is Nutrien (formerly PCS prior to the merger with Agrium Inc. on January 1, 2018), which currently owns 32% of the total outstanding shares of SQM. Nutrien is required to divest all of its ownership in SQM within 18 months of the merger with Agrium Inc. pursuant to the terms of the approval of the merger of PCS and Agrium Inc. by the Competition Commission of India. As of the date of this Annual Report on Form 20-F, Nutrien has not yet completed the sale of any portion of its interest in SQM.

The other principal shareholder group consists of the Pampa Group and the Kowa Group (each as defined in “Item 7.A. Major Shareholders”), which currently owns 32.49% of the total outstanding shares of SQM. This shareholder group may lose its Controller Group status under Chilean law upon the termination of the Joint Operation Agreement (as defined in “Item 7.A. Major Shareholders”) as required under the Pampa Group Agreement entered into by the Pampa Group members in connection with the Corfo Arbitration Agreement. See “Item 7.A. Major Shareholders”.

In addition, on April 17, 2017, certain entities owned by the Pampa Group, the Kowa Group and PCS entered into an agreement with respect to certain corporate governance matters of SQM. See “Item 7.A. Major Shareholders”.

The divestiture by Nutrien, the loss of the Controller Group status by the Pampa Group and the Kowa Group, or a combination thereof, may have a material adverse effect on our business, financial condition and results of operations.

Risks Relating to Financial Markets

Currency fluctuations may have a negative effect on our financial performance

We transact a significant portion of our business in U.S. dollars, and the U.S. dollar is the currency of the primary economic environment in which we operate. In addition, the U.S. dollar is our functional currency for financial statement reporting purposes. A significant portion of our costs, however, is related to the Chilean peso. Therefore, an increase or decrease in the exchange rate between the Chilean peso and the U.S. dollar would affect our costs of production. The Chilean peso has been subject to large devaluations and revaluations in the past and may be subject to significant fluctuations in the future. As of December 31, 2017, the Chilean peso exchange rate was Ch$614.75 per U.S. dollar, while as of December 31, 2016, the Chilean peso exchange rate was Ch$669.47 per U.S. dollar. The Chilean peso therefore appreciated against the U.S. dollar by 8.0% in 2017. As of April 18, 2018, the Observed Exchange Rate was Ch$595.82 per U.S. dollar.

As an international company operating in several other countries, we also transact business and have assets and liabilities in other non-U.S. dollar currencies, such as, among others, the Euro, the South African rand, the Mexican peso, the Chinese yuan, the Thai baht and the Brazilian real. As a result, fluctuations in the exchange rates of such foreign currencies to the U.S. dollar may have a material adverse effect on our business, financial condition and results of operations.

| 16 |

Interest rate fluctuations may have a material impact on our financial performance

As of December 31, 2017, we did not have any outstanding short or long-term debt bearing interest based on LIBOR or other variable interest rates. Should we have such debt in the future, a relative increase in the rate could materially impact our business, financial condition and results of operations.

Risks Relating to Chile

As we are a company based in Chile, we are exposed to Chilean political risks

Our business, results of operations, financial condition and prospects could be affected by changes in policies of the Chilean government, other political developments in or affecting Chile, legal changes in the standards or administrative practices of Chilean authorities or the interpretation of such standards and practices, over which we have no control.

Changes in regulations regarding, or any revocation or suspension of our concessions could negatively affect our business

Any changes to regulations to which we are subject or adverse changes to our concession rights, or a revocation or suspension of our concessions, could have a material adverse effect on our business, financial condition and results of operations.

Changes in mining or port concessions could affect our operating costs

We conduct our mining operations, including brine extraction, under exploitation and exploration concessions granted in accordance with provisions of the Chilean constitution and related laws and statutes. Our exploitation concessions essentially grant a perpetual right (with the exception of the rights granted to SQM Salar with respect to the Salar de Atacama concessions under the Lease Agreement described above, which expires in 2030) to conduct mining operations in the areas covered by the concessions, provided that we pay annual concession fees. Our exploration concessions permit us to explore for mineral resources on the land covered thereby for a specified period of time and to subsequently request a corresponding exploitation concession.

We also operate port facilities at Tocopilla, Chile, for the shipment of products and the delivery of raw materials pursuant to maritime concessions, which have been granted under applicable Chilean laws and are normally renewable on application, provided that such facilities are used as authorized and annual concession fees are paid.

Any significant adverse changes to any of these concessions could have a material adverse effect on our business, financial condition and results of operations.

Changes in water rights laws and other regulations could affect our operating costs

We hold water use rights that are key to our operations. These rights were obtained from the Chilean Water Authority (Dirección General de Aguas) for supply of water from rivers and wells near our production facilities, which we believe are sufficient to meet current operating requirements. However, the Chilean water rights code (Código de Aguas or the “Water Code”) is subject to changes, which could have a material adverse impact on our business, financial condition and results of operations. For example, a series of bills are currently being discussed at the Chilean National Congress that seek to desalinate seawater for use in mining production processes, amend the Mining Code for water use in mining operations, amend the Political Constitution on water and introduce changes to the regulatory framework governing the terms of inspection and sanction of water. As a result, the amount of water that we can actually use under our existing rights may be reduced or the cost of such use could increase. These and potential future changes to the Water Code or other relevant regulations could have a material adverse effect on our business, financial condition and results of operations.

| 17 |

The Chilean government could levy additional taxes on corporations operating in Chile

In Chile, there is a royalty tax that is applied to mining activities developed in the country.

On September 29, 2014, Law No. 20,780 was published (the “Tax Reform”), introducing significant changes to the Chilean taxation system and strengthening the powers of the SII to control and prevent tax avoidance. Subsequently, on February 8, 2016, Law No. 20,899 that simplifies the income tax system and modifies other legal tax provisions was published. As a result of these reforms, open stock corporations like SQM are subject to the partially integrated shareholder tax regime (sistema parcialmente integrado). The corporate tax rate applicable to us increased to 25.5% in 2017 and will increase to a maximum rate of 27% in 2018.

Under the partially integrated shareholder taxation regime, shareholders bear the tax on dividends upon payment, but they will only be permitted to credit against such shareholder taxes a portion of the Chilean corporate tax paid by us on our earnings, unless the shareholder is resident in a country with a tax treaty in force with Chile or signed with Chile prior to January 1, 2017, whether or not in force. In that case, 100% of the Chilean corporate tax paid by us may be credited against the final taxes at the shareholder level.

As a result, foreign shareholders resident in a non-treaty jurisdiction will be subject to a higher effective tax rate than residents of treaty jurisdictions. There is a temporary rule in effect from January 1, 2017 through December 31, 2019 that treaty jurisdictions for this purpose will include jurisdictions with tax treaties signed with Chile prior to January 1, 2017, whether or not such treaties are in force. This is currently the status of the treaty signed between Chile and United States.

The Tax Reform tax increase prompted a US$52.3 million increase in our deferred tax liabilities as of December 31, 2014. In accordance with IAS 12, the effects generated by the change in the income tax rate approved by Law No. 20.780 on income and deferred taxes were applied to the income statement. For purposes of the Company’s statutory consolidated financial statements filed with the CMF, in accordance with the instructions issued by the CMF in its circular 856 of October 17, 2014, the effects generated by the change in the income tax rate were accounted for as retained earnings. The amount charged to equity as of December 31, 2014 was US$52.3 million, thereby giving rise to a difference of US$52.3 million in profit for the year and income tax expense as presented in the Company’s Audited Consolidated Financial Statements compared with profit and income tax expense as presented in the Company’s statutory consolidated financial statements filed with the CMF.

In addition, the Tax Reform may have other material adverse effects on our business, financial condition and results of operations. Likewise, we cannot assure you that the manner in which the Royalty Law (as defined below) or the corporate tax rate are interpreted and applied will not change in the future. The Chilean government may decide to levy additional taxes on mining companies or other corporations in Chile. Such changes could have a material adverse effect on our business, financial condition and results of operations.

| 18 |

Ratification of the International Labor Organization’s Convention 169 concerning indigenous and tribal peoples might affect our development plans

Chile, a member of the International Labor Organization (“ILO”), has ratified the ILO’s Convention 169 (the “Indigenous Rights Convention”) concerning indigenous and tribal people. The Indigenous Rights Convention established several rights for indigenous people and communities. Among other rights, the Indigenous Rights Convention states that (i) indigenous groups should be notified and consulted prior to the development of any project on land deemed indigenous, although veto rights are not mentioned and (ii) indigenous groups have, to the extent possible, a stake in benefits resulting from the exploitation of natural resources in indigenous land. The extent of these benefits has not been defined by the Chilean government. The Chilean government has addressed item (i) above through Supreme Decree No. 66, issued by the Social Development Ministry. This decree requires government entities to consult indigenous groups that may be directly affected by the adoption of legislative or administrative measures, and it also defines criteria for the projects or activities that must be reviewed through the environmental evaluation system that also require such consultation. To the extent that the new rights outlined in the Indigenous Rights Convention become laws or regulations in Chile, they could affect the development of our investment projects in lands that have been defined as indigenous, which could have a material adverse effect on our business, financial condition and results of operations.

Chile is located in a seismically active region

Chile is prone to earthquakes because it is located along major fault lines. The most recent major earthquakes in Chile, which occurred in April 2017 in the Valparaiso region and in December 2016 in Chiloe Island, had a magnitude of 6.9 and 7.6, respectively, on the Richter scale. There were also earthquakes in 2015, 2014 and 2010 that caused substantial damage to some areas of the country. Chile has also experienced volcanic activity. A major earthquake or a volcanic eruption could have significant negative consequences for our operations and for the general infrastructure, such as roads, rail, and access to goods, in Chile. Although we maintain industry standard insurance policies that include earthquake coverage, we cannot assure you that a future seismic or volcanic event will not have a material adverse effect on our business, financial condition and results of operations.

Risks Relating to our Shares and to our ADSs

The price of our ADSs and the U.S. dollar value of any dividends will be affected by fluctuations in the U.S. dollar/Chilean peso exchange rate

Chilean trading in the shares underlying our ADSs is conducted in Chilean pesos. The depositary will receive cash distributions that we make with respect to the shares in Chilean pesos. The depositary will convert such Chilean pesos to U.S. dollars at the then prevailing exchange rate to make dividend and other distribution payments in respect of ADSs. If the value of the Chilean peso falls relative to the U.S. dollar, the value of the ADSs and any distributions to be received from the depositary will decrease.

Developments in other emerging markets could materially affect the value of our ADSs and our shares

The Chilean financial and securities markets are, to varying degrees, influenced by economic and market conditions in other emerging market countries or regions of the world. Although economic conditions are different in each country or region, investor reaction to developments in one country or region can have significant effects on the securities of issuers in other countries and regions, including Chile and Latin America. Events in other parts of the world may have a material effect on Chilean financial and securities markets and on the value of our ADSs and our shares.

The volatility and low liquidity of the Chilean securities markets could affect the ability of our shareholders to sell our ADSs

The Chilean securities markets are substantially smaller, less liquid and more volatile than the major securities markets in the United States. The volatility and low liquidity of the Chilean markets could increase the price volatility of our ADSs and may impair the ability of a holder to sell our ADSs into the Chilean market in the amount and at the price and time he wishes to do so.

| 19 |

Our share or ADS price may react negatively to future acquisitions and investments

As world leaders in our core businesses, part of our strategy is to look for opportunities that will allow us to consolidate and strengthen our competitive position in jurisdictions in which we currently do not operate. Pursuant to this strategy, we may carry out acquisitions or joint ventures relating to any of our businesses or to new businesses in which we believe we may have sustainable competitive advantages. Depending on our capital structure at the time of such acquisitions or joint ventures, we may need to raise significant debt and/or equity which will affect our financial condition and future cash flows. Any change in our financial condition could affect our results of operations, negatively impacting our share or ADS price.

ADS holders may be unable to enforce rights under U.S. securities laws

Because we are a Chilean company subject to Chilean law, the rights of our shareholders may differ from the rights of shareholders in companies incorporated in the United States, and ADS holders may not be able to enforce or may have difficulty enforcing rights currently in effect under U.S. federal or state securities laws.

Our Company is an open stock corporation incorporated under the laws of the Republic of Chile. Most of our directors and officers reside outside the United States, principally in Chile. All or a substantial portion of the assets of these persons are located outside the United States. As a result, if any of our shareholders, including holders of our ADSs, were to bring a lawsuit against our officers or directors in the United States, it may be difficult for them to effect service of legal process within the United States upon these persons. Likewise, it may be difficult for them to enforce judgments obtained in United States courts based upon the civil liability provisions of the federal securities laws in the United States against them in the United States.

In addition, there is no treaty between the United States and Chile providing for the reciprocal enforcement of foreign judgments. However, Chilean courts have enforced judgments rendered in the United States, provided that the Chilean court finds that the United States court respected basic principles of due process and public policy. Nevertheless, there is doubt as to whether an action could be brought successfully in Chile in the first instance on the basis of liability based solely upon the civil liability provisions of the United States federal securities laws.

As preemptive rights may be unavailable for our ADS holders, they have the risk of their holdings being diluted if we issue new stock

Chilean laws require companies to offer their shareholders preemptive rights whenever issuing new shares of capital stock so shareholders can maintain their existing ownership percentage in a company. If we increase our capital by issuing new shares, a holder may subscribe for up to the number of shares that would prevent dilution of the holder’s ownership interest.

If we issue preemptive rights, United States holders of ADSs would not be able to exercise their rights unless a registration statement under the Securities Act were effective with respect to such rights and the shares issuable upon exercise of such rights or an exemption from registration were available. We cannot assure holders of ADSs that we will file a registration statement or that an exemption from registration will be available. We may, in our absolute discretion, decide not to prepare and file such a registration statement. If our holders were unable to exercise their preemptive rights because we did not file a registration statement, the depositary bank would attempt to sell their rights and distribute the net proceeds from the sale to them, after deducting the depositary’s fees and expenses. If the depositary could not sell the rights, they would expire and holders of ADSs would not realize any value from them. In either case, ADS holders’ equity interest in us would be diluted in proportion to the increase in our capital stock.

If we were classified as a Passive Foreign Investment Company by the U.S. Internal Revenue Service, there could be adverse consequences for U.S. investors

We believe that we were not classified as a Passive Foreign Investment Company (“PFIC”) for 2017. Characterization as a PFIC could result in adverse U.S. tax consequences to you if you are a U.S. investor in our shares or ADSs. For example, if we (or any of our subsidiaries) are a PFIC, our U.S. investors may become subject to increased tax liabilities under U.S. tax laws and regulations and will become subject to burdensome reporting requirements. The determination of whether or not we (or any of our subsidiaries or portfolio companies) are a PFIC is made on an annual basis and will depend on the composition of our (or their) income and assets from time to time. See “Item 10.E. Taxation—United States Tax Considerations.”

U.S. federal income tax reform could adversely affect us and holders of our shares and ADSs

On December 22, 2017, President Trump signed into law H.R. 1, originally known as the “Tax Cuts and Jobs Act,” which significantly reformed the Internal Revenue Code of 1986, as amended. The impact of this tax reform, or of any future administrative guidance interpreting provisions thereof, on holders of our ADSs or shares is uncertain and could be adverse. Prospective investors are urged to consult with their own legal and tax advisors with respect to any such legislation and the potential tax consequences of purchasing, holding, and disposing of our shares and ADSs.

Changes in Chilean tax regulations could have adverse consequences for U.S. investors

Currently cash dividends paid by us to foreign shareholders are subject to a 35% Chilean withholding tax. When the Company pays a corporate income tax on the income from which the dividend is paid, known as a “First Category Tax”, a credit for the full amount of the First Category Tax effectively reduces the rate of Withholding Tax. Changes in Chilean tax regulations could have adverse consequences for U.S. investors. See “Item 3.D. Risk Factors—Risks Relating to Chile—The Chilean Government Could Levy Additional Taxes on Corporations Operating in Chile” and “Item 10.E. Taxation—Material Chilean Tax Considerations.”

4.A. History and Development of the Company

Historical Background

Sociedad Química y Minera de Chile S.A. is an open stock corporation organized under the laws of the Republic of Chile. We were constituted by public deed issued on June 17, 1968 by the Notary Public of Santiago, Mr. Sergio Rodríguez Garcés. Our existence was approved by Decree No. 1,164 of June 22, 1968 of the Ministry of Finance, and we were registered on June 29, 1968 in the Registry of Commerce of Santiago, on page 4,537 No. 1,992. Our headquarters is located at El Trovador 4285, Fl. 6, Las Condes, Santiago, Chile. Our telephone number is +56 2 2425-2000. We are legally referred to by our full name Sociedad Química y Minera de Chile S.A. as well as by the abbreviated name “SQM.”

Commercial exploitation of the caliche ore deposits in northern Chile began in the 1830s, when sodium nitrate was extracted from the ore for use in the manufacturing of explosives and fertilizers. By the end of the nineteenth century, nitrate production had become the leading industry in Chile, and the country was the world’s leading supplier of nitrates. The accelerated commercial development of synthetic nitrates in the 1920s and the global economic depression in the 1930s caused a serious contraction of the Chilean nitrate business, which did not recover significantly until shortly before the Second World War. After the war, the widespread commercial production of synthetic nitrates resulted in a further contraction of the natural nitrate industry in Chile, which continued to operate at depressed levels into the 1960s.

| 21 |

We were formed in 1968 through a joint venture between Compañía Salitrera Anglo Lautaro S.A. (“Anglo Lautaro”) and Corfo, a Chilean government entity. Three years after our formation, in 1971, Anglo Lautaro sold all of its shares to Corfo, and we were wholly owned by the Chilean Government until 1983. In 1983, Corfo began a process of privatization by selling our shares to the public and subsequently listing such shares on the Santiago Stock Exchange. By 1988, all of our shares were publicly owned. Our ADSs have traded on the NYSE under the ticker symbol “SQM” since 1993. Each ADS represents one Series B common share. We accessed international capital markets again for the issuance of additional ADSs in 1995 and 1999.

Since our inception, we have produced nitrates and iodine, which are obtained from the caliche ore deposits in northern Chile. In 1985, we began to use heap leaching processes to extract nitrates and iodine, and in 1986 we started to produce potassium nitrate at our Coya Sur facility. Between 1994 and 1999, we invested approximately US$300 million in the development of the Salar de Atacama project in northern Chile, which enabled us to produce potassium chloride, lithium carbonate, potassium sulfate and boric acid.

From 2000 through 2004, we principally consolidated the investments carried out in the preceding five years. We focused on reducing costs and improving efficiencies throughout the organization. In addition, in 2001, we signed a commercial distribution agreement with the Norwegian company Yara International ASA, in order to take advantage of cost synergies in the Specialty Plant Nutrition business line.

Starting in 2005, we began strengthening our leadership position in our core businesses through a combination of capital expenditures and advantageous acquisitions and divestitures. Our acquisitions have included the Kemira Emirates Fertiliser Company (“Kefco”) in Dubai in 2005 and the iodine business of Royal DSM N.V. (“DSM”) in 2006. We also entered into a number of joint ventures, including a joint venture with Migao Corporation (“Migao”), signed in 2008, for the production of potassium nitrate, and SQM VITAS, our joint venture with the French Roullier Group. Pursuant to the latter joint venture, in 2010, we launched a new line of soluble phosphate products, and in 2012 we built new plants for the production of water-soluble fertilizers in Brazil (Candeias), Peru and South Africa (Durban). We have also sold: (i) Fertilizantes Olmeca, our former Mexican subsidiary, in 2006, (ii) our stake in Impronta S.R.L., our former Italian subsidiary, in 2007 and (iii) our former butyllithium plant located in Houston, Texas, in 2008. These sales allowed us to concentrate our efforts on our core products.

The capital expenditure program has allowed us to add new products to our product lines and increase the production capacity of our existing products. In 2005, we started production of lithium hydroxide at a plant in the Salar del Carmen, near the city of Antofagasta in the north of Chile. In 2007, we completed the construction of a new prilling and granulating plant for nitrates in Coya Sur. In 2011, we completed expansions of our lithium carbonate capacity, achieving 48,000 metric tons of capacity per year. Since 2010, we have continued to expand our production capacity of potassium products in our operations in the Salar de Atacama. In 2011, we completed the construction of a new potassium nitrate facility in Coya Sur, increasing our overall production capacity of potassium nitrate by 300,000 metric tons per year. In 2013, we completed expansions in the production capacity of our iodine plants in Nueva Victoria. Our capital expenditure program also includes exploration for metallic minerals. Our exploration efforts have led to discoveries that in some cases may result in sales of the discovery and the generation of royalty income in the future. Within this context, in 2013 we sold our royalty rights to the Antucoya mining project to Antofagasta Minerals. In 2013 we also opened a trading office in Thailand.

In 2014, we invested in the development of new extraction sectors and production increases in both nitrates and iodine at Nueva Victoria, reaching an approximate production capacity (including the Iris facility) of 8,500 metric tons per year of iodine at the facility. We also issued a bond in the international capital markets for US$250 million, primarily to refinance existing indebtedness.

| 22 |

In 2015, we focused on increasing the efficiency of our operations. Within this context, we announced a plan to restructure our iodine and nitrate operations. In an effort to take advantage of our highly efficient production facilities at our Nueva Victoria site, we decided to suspend the mining and nitrate operations and reduce iodine production at our Pedro de Valdivia site. During 2017, we increased our iodine production capacity at Nueva Victoria to approximately 10,000 metric tons per year. Including Pedro de Valdivia and Nueva Victoria, our current effective iodine capacity is approximately 11,000 metric tons per year.

In 2016, we entered into a 50/50 joint venture with Lithium Americas to develop the Minera Exar lithium project in Caucharí-Olaroz in the Jujuy province of Argentina. Under the current project timeline, we expect to commission the first stage of 25,000 metric tons plant production by 2020. We also made a capital contribution of US$20 million to Elemental Minerals Limited (“Elemental Minerals”), an Australian based company whose main assets are various potassium deposits in the Republic of Congo. We invested approximately US$20 million in exchange for 18% of the company, and a right of first refusal for approximately 20% of the total potash production of Elemental Minerals. Following this transaction at the end of 2016, Elemental Minerals changed its name to Kore Potash Limited. The State General Reserve Fund of Oman contributed US$20 million. These investments are not included in the capital expenditure program amounts discussed in the section below. These investments were carried out with internal financing.

In 2017, we continued to expand our operations outside Chile and, together with our subsidiary SQM Australia Pty, acquired 50% of the assets of the Mount Holland lithium project in Western Australia, Australia. We entered into a 50/50 joint venture with Kidman Resources Limited to develop mining operations and construct concentration and refining plants to produce 40,000 metric tons per year of lithium carbonate and lithium hydroxide, starting in 2021. Kidman Resources Limited will retain the exclusive right to exploit gold within the project area. According to the agreement, SQM Australia Pty committed to pay a price of US$35 million, subject to compliance with conditions established in the agreement. As of December 31, 2017, no payments had been made yet.

Capital Expenditure Program

We regularly review different opportunities to improve our production methods, reduce costs, increase production capacity of existing products and develop new products and markets. Additionally, significant capital expenditures are required every year in order to sustain our production capacity. We are focused on developing new products in response to identified customer demand, as well as new products that can be derived as part of our existing production or other products that could fit our long-term development strategy. Our capital expenditures in Chile have been mainly related to the organic growth and sustainability of our business, including the construction of new facilities and the renovation of plants and equipment. From 2016 we began to invest in lithium projects outside Chile, starting with the Minera Exar project in Argentina and continuing with Mount Holland project in Australia in 2017.

Our capital expenditures for the years ended December 31, 2017, 2016 and 2015 were as follows:

(in millions of US$) |  | 2017 |  |  | 2016 |  |  | 2015 |
Capital expenditures |  |  | 142.1 |  |  |  | 131.3 |  |  |  | 111.3 |

During 2017, we had total capital expenditures of US$142.1 million, primarily related to:

| · | Capacity expansion projects related to lithium carbonate and lithium hydroxide production in Chile;

| 23 |

| · | Investments in mining workshop and operations centers to relocate operations from Nueva Victoria mine to mining sector Tente en el Aire;

| · | Capacity expansion project related to potassium nitrate production;

| · | General maintenance of all production units and Tocopilla port in order to ensure the fulfillment of production and sales targets.

During 2016, we had total capital expenditures of US$131.3 million, primarily related to:

| · | Completion of the project related to the expansion of ponds at Nueva Victoria to increase the production of iodine and nitrates;

| · | Capacity expansion projects related to our potassium nitrate production;

| · | Capacity expansion project related to our lithium hydroxide production;

| · | Improvements in the open storage areas at the Port of Tocopilla;

| · | General maintenance of all production units in order to ensure the fulfillment of production targets and the safety of all of our employees.

During 2015, we had total capital expenditures of US$111.3 million, primarily related to:

| · | Expansion of ponds at Nueva Victoria in order to increase the production of iodine and nitrates;

| · | Refining system at potassium nitrate plants;

| · | Exploration and construction of new wells to sustain production at the Salar de Atacama and

| · | Maintenance of production facilities in order to ensure production goals are met, as well as improvements in the open storage areas at the Port of Tocopilla.

The Board of Directors has approved a capital expenditure framework for 2018 of approximately US$517 million focused on the maintenance of our production facilities in order to strengthen our ability to meet our production goals and to increase our production capacity, primarily in lithium. We estimate that we will invest approximately US$360 million in our operations in Chile, including maintenance of our production facilities, an additional expansion of lithium carbonate capacity to 100,000 metric tons, completion of hydroxide capacity expansion, the expansion of iodine production capacity in Nueva Victoria and the expansion of productive capacity of potassium nitrate in Coya Sur. Our projected investments of approximately US$157 million in projects outside Chile include the development of lithium projects Minera Exar in Argentina and Mount Holland in Australia. We do not expect that our 2018 capital investment program will require external financing. However, we always have the option to access capital markets in order to optimize our financial position.

4.B. Business Overview

The Company

We believe that we are the world’s largest producer of potassium nitrate and iodine and one of the world´s largest lithium producers. We also produce specialty plant nutrients, iodine derivatives, lithium derivatives, potassium chloride, potassium sulfate and certain industrial chemicals (including industrial nitrates and solar salts). Our products are sold in over 110 countries through our worldwide distribution network, with 93% of our sales in 2017 derived from countries outside Chile.

Our products are mainly derived from mineral deposits found in northern Chile. We mine and process caliche ore and brine deposits. The caliche ore in northern Chile contains the only known nitrate and iodine deposits in the world and is the world’s largest commercially exploited source of natural nitrates. The brine deposits of the Salar de Atacama, a salt-encrusted depression in the Atacama Desert in northern Chile, contain high concentrations of lithium and potassium as well as significant concentrations of sulfate and boron.

| 24 |

From our caliche ore deposits, we produce a wide range of nitrate-based products used for specialty plant nutrients and industrial applications, as well as iodine and iodine derivatives. At the Salar de Atacama, we extract brines rich in potassium, lithium, sulfate and boron in order to produce potassium chloride, potassium sulfate, lithium solutions and bischofite (magnesium chloride). We produce lithium carbonate and lithium hydroxide at our plant near the city of Antofagasta, Chile, from the solutions brought from the Salar de Atacama. We market all of these products through an established worldwide distribution network.

Our products are divided into six categories: specialty plant nutrients; iodine and its derivatives; lithium and its derivatives; potassium chloride and potassium sulfate; industrial chemicals and other commodity fertilizers. Specialty plant nutrients are premium fertilizers that enable farmers to improve yields and the quality of certain crops. Iodine and its derivatives are mainly used in the X-ray contrast media and biocides industries and in the production of polarizing film, which is an important component in LCD screens. Lithium and its derivatives are mainly used in batteries, greases and frits for production of ceramics. Potassium chloride is a commodity fertilizer that is produced and sold by us worldwide. Potassium sulfate is a specialty fertilizer used primarily in crops such as vegetables, fruits and industrial crops. Industrial chemicals have a wide range of applications in certain chemical processes such as the manufacturing of glass, explosives and ceramics, and, more recently, industrial nitrates are being used in concentrated solar power plants as a means for energy storage. In addition, we complement our portfolio of plant nutrients through the buying and selling of other commodity fertilizers for use mainly in Chile.

For the year ended December 31, 2017, we had revenues of US$2,157.3 million, gross profit of US$762.5 million and profit attributable to controlling interests of US$427.7 million. Our worldwide market capitalization as of December 31, 2017 was approximately US$15.4 billion.

Specialty Plant Nutrition: We produce four main types of specialty plant nutrients: potassium nitrate, sodium nitrate, sodium potassium nitrate and specialty blends. We also sell other specialty fertilizers including third party products. All of these specialty plant nutrients are used in either solid or liquid form mainly on high value crops such as vegetables, fruits and flowers. Our nutrients are widely used in crops that employ modern agricultural techniques such as hydroponics, green housing, fertigation (where fertilizer is dissolved in water prior to irrigation) and foliar application. According to the type of use or application, our products are primarily marketed under the following brands: Ultrasol™ (fertigation), Qrop™ (open field application), Speedfol™ (foliar application) and Allganic™ (organic farming). Specialty plant nutrients have certain advantages over commodity fertilizers, such as rapid and effective absorption (without requiring nitrification), superior water solubility, increased soil pH (which reduces soil acidity) and low chloride content. One of the most important products in this business line is potassium nitrate, which is sold in crystalline or prill form, allowing for multiple application methods. Crystalline potassium nitrate products are ideal for application by fertigation and foliar sprays, and potassium nitrate prills are suitable for soil applications.

The new needs of more sophisticated customers demand that the industry provide integrated solutions rather than individual products. Our products, including customized specialty blends that meet specific needs along with the agronomic service provided, allow to create plant nutrition solutions that add value to crops through higher yields and better quality production. Because our products are derived from natural nitrate compounds or natural potassium brines, they have certain advantages over synthetically produced fertilizers, including the presence of certain beneficial trace elements, which makes them more attractive to customers who prefer products of natural origin. As a result, specialty plant nutrients are sold at a premium price compared to commodity fertilizers.

Iodine and its Derivatives: We believe that we are the world’s leading producer of iodine and iodine derivatives, which are used in a wide range of medical, pharmaceutical, agricultural and industrial applications, including x-ray contrast media, polarizing films for LCD and LED, antiseptics, biocides and disinfectants, in the synthesis of pharmaceuticals, electronics, pigments and dye components. We market iodine using the brand QIodine™.

| 25 |

Lithium and its Derivatives: We are a leading producer of lithium carbonate, which is used in a variety of applications, including electrochemical materials for batteries, frits for the ceramic and enamel industries, heat-resistant glass (ceramic glass), air conditioning chemicals, continuous casting powder for steel extrusion, primary aluminum smelting process, pharmaceuticals and lithium derivatives. We are also a leading supplier of lithium hydroxide, which is primarily used as an input for the lubricating greases industry and for certain cathodes for batteries. We market lithium using the following brands: QLithiumCarbonate™, QLithiumHydroxide™ and QLubelith™.

Potassium: We produce potassium chloride and potassium sulfate from brines extracted from the Salar de Atacama. Potassium chloride is a commodity fertilizer used to fertilize a variety of crops including corn, rice, sugar, soybean and wheat. Potassium sulfate is a specialty fertilizer used mainly in crops such as vegetables, fruits and industrial crops.

Industrial Chemicals: We produce three industrial chemicals: sodium nitrate, potassium nitrate and potassium chloride. Sodium nitrate is used primarily in the production of glass, explosives, and metal treatment. Potassium nitrate is used in the manufacturing of specialty glass, and it is also an important raw material for the production of frits for the ceramics and enamel industries. Solar salts, a combination of potassium nitrate and sodium nitrate, are used as a thermal storage medium in concentrated solar power plants. Potassium chloride is a basic chemical used to produce potassium hydroxide, and it is also used as an additive in oil drilling as well as in food processing, among other uses. We market our industrial chemicals using the following brands: QSodiumNitrate™, QPotassiumNitrate™, and QPotassiumChloride™.

Other Products and Services: We also sell other fertilizers and blends, some of which we do not produce. We are the largest company that produces and distributes the three main potassium sources: potassium nitrate, potassium sulfate and potassium chloride.

The following table shows the percentage breakdown of our revenues for 2017, 2016 and 2015 according to our product lines:

|  | 2017 |  |  | 2016 |  |  | 2015 |

Business Strategy

Our business strategy is to be a global company with people committed to excellence, dedicated to the extraction of minerals and selectively integrated in the production and sale of products for the industries essential for human development (e.g. food, health, technology). This strategy was built on the following five principles:

| · | ensure availability of key resources required to support current goals and medium and long-term growth of the business;

| · | consolidate a culture of lean operations (M1 excellence) through the entire organization, including operations, sales and support areas;

| · | significantly increase nitrate sales in all its applications and ensure consistency with iodine commercial strategy;

| 26 |

| · | maximize the margins of each business line through appropriate pricing strategy;

| · | successfully develop and implement all lithium expansion projects of the Company, acquire more lithium and potassium assets to generate a competitive portfolio.

These principles are based on the following key concepts:

| · | strengthen the organizational structure to supports the development of the Company's strategic plan, focusing on the development of critical capabilities and the application of the corporate values of Excellence, Integrity and Safety;

| · | develop a robust risk control and mitigation process to actively manage business risk;

| · | improve our stakeholder management to establish links with the community and communicate to Chile and worldwide our contribution to industries essential for human development.

We have identified market demand in each of our major product lines, both within our existing customer base and in new markets, for existing products and for additional products that can be produced from our natural resources. To take advantage of these opportunities, we have developed specific strategies for each of our product lines.

Specialty Plant Nutrition

Our strategy in our specialty plant nutrition business is to: (i) leverage the advantages of our specialty products over commodity-type fertilizers; (ii) selectively expand our business by increasing our sales of higher margin specialty plant nutrients based on potassium and natural nitrates, particularly soluble potassium nitrate and NPK blends; (iii) pursue investment opportunities in complementary businesses to enhance our product portfolio, increase production, reduce costs, and add value to the marketing of our products; (iv) develop new specialty nutrient blends produced in our mixing plants that are strategically located in or near our principal markets in order to meet specific customer needs; (v) focus primarily on the markets where we can sell our plant nutrients in soluble and foliar applications in order to establish a leadership position; (vi) further develop our global distribution and marketing system directly and through strategic alliances with other producers and global or local distributors; (vii) reduce our production costs through improved processes and higher labor productivity so as to compete more effectively and (viii) supply a product with consistent quality according to the specific requirements of our customers.

Iodine and its Derivatives

Our strategy in our iodine business is to: (i) reach and maintain our market share of approximately one third of the iodine market in order to optimize the use of our available production capacity; (ii) encourage demand growth and promote new iodine uses; (iii) participate in iodine recycling projects through the Ajay-SQM Group (“ASG”); (iv) reduce our production costs through improved processes and higher productivity in order to compete more effectively and (v) supply a product with consistent quality according to the requirements of our customers.

Lithium and its Derivatives

Our strategy in our lithium business is to: (i) strategically allocate our sales of lithium carbonate and lithium hydroxide; (ii) encourage demand growth and promote new lithium uses; (iii) selectively pursue opportunities in the lithium derivatives business by creating new lithium compounds; (iv) reduce our production costs through improved processes and higher productivity in order to compete more effectively; (v) supply a product with consistent quality according to the requirements of our customers and (vi) diversify our operations geographically and jurisdictionally.

Potassium

Our strategy in our potassium business is to: (i) offer a portfolio of potassium products, including potassium sulfate, potassium chloride and other fertilizers, to our traditional markets; (ii) have flexibility to offer crystalized (standard) or granular (compacted) form products according to market requirements; (iii) focus on markets where we have logistical advantages and synergies with our specialty plant nutrition business and (iv) supply a product with consistent quality according to the specific requirements of our customers.

| 27 |

Industrial Chemicals

Our strategy in our industrial chemical business is to: (i) maintain our leadership position in the industrial nitrates market as well as increase our supply of potassium chloride in markets where we have natural advantages; (ii) encourage demand growth in different applications; (iii) become a long-term, reliable supplier for the thermal storage industry, maintaining close relationships with R&D programs; (iv) reduce our production costs through improved processes and higher productivity in order to compete more effectively and (v) supply a product with consistent quality according to the requirements of our customers.

New Business Ventures

We always evaluate opportunities to expand in our current core businesses or within new businesses in which we believe we may have sustainable competitive advantages, both within and outside Chile, and we expect to continue to do so in the future.

We continuously explore the possibility of acquiring controlling stakes or other interests in companies that have mining properties and operations in our core business areas and new businesses. Consistent with our business strategy, we will continue to evaluate acquisitions, joint ventures and alliances in our current and new businesses and, depending on all facts and circumstances, may seek to acquire controlling stakes or other interests related to our core businesses both inside and outside of Chile, including other emerging markets.

In addition, we are actively conducting exploration for metallic minerals in the mining properties we own. If such minerals are found, we may decide to exploit, sell or enter into an association to extract these resources. Our exploration efforts are currently focused on the layer of bedrock that lies beneath the caliche ore that we use as the primary raw material in the production of iodine and nitrates. This bedrock has significant potential for metallic mineralization, particularly copper and gold. A significant portion of our mining properties are located in the Antofagasta region of Chile, where many large copper producers operate.

We have an in-house geological exploration team that explores the area directly, drilling targets and assessing new prospects. In 2017, the team identified 13 new targets and confirmed mineralization in four of the targets, using its own truck-mounted drill rigs. The number of perforated meters reached 28,000 meters, and were made with three machines of which two were internal and the other external. We also have a metal business development team that works to engage partners interested in investing in metal exploration within our mining properties. As of December 31, 2017, we had ten option agreements in place with seven companies, including small junior mining companies, private equity firms and large mining companies.

Main Business Lines

Specialty Plant Nutrition

We believe that we are the world’s largest producer of potassium nitrate. We estimate that our sales accounted for approximately 54% of global potassium nitrate sales for all applications by volume in 2017, an increase from 44% in 2016. During 2017, the potassium nitrate market increased by approximately 4%. These estimates do not include potassium nitrate produced and sold locally in China, only Chinese net imports and exports.

| 28 |

In addition to potassium nitrate, we produce the following specialty plant nutrients: sodium nitrate, sodium potassium nitrate and specialty blends (containing various combinations of nitrogen, phosphate and potassium and generally known as “NPK blends”).

Our specialty plant nutrients have specific characteristics that increase productivity and enhance quality when used on certain crops and soils. Our specialty plant nutrients have significant advantages for certain applications over commodity fertilizers based on nitrogen and potassium, such as urea and potassium chloride.

Our specialty plant nutrients advantages are:

| · | fully water soluble, allowing their more efficient use in hydroponics, fertigation, foliar applications and other advanced agricultural techniques;

| · | improve the water use efficiency of crops and help conserve water;

| · | chloride-free, which prevents chloride toxicity in certain crops associated with high levels of chlorine in plant nutrients;

| · | provide nitrogen in nitric form, thereby allowing crops to absorb nutrients faster than they absorb urea or ammonium-based fertilizers;

| · | do not release hydrogen after application, thereby avoiding increased soil acidity;

| · | possess trace elements, which promote disease resistance in plants and

| · | more attractive to customers who prefer products of natural origin.

In 2017, our specialty plant nutrients revenues increased to US$697.3 million, representing 32% of our total revenues for that year and a 11.8% increase from US$623.9 million in specialty plant nutrients revenues in 2016. Prices decreased approximately 2.7% in 2017.

Specialty Plant Nutrition: Market

The target market for our specialty plant nutrients includes producers of high-value crops such as vegetables, fruits, industrial crops, flowers, cotton and others. Furthermore, we sell specialty plant nutrients to producers of chloride-sensitive crops. Since 1990, the international market for specialty plant nutrients has grown at a faster rate than the international market for commodity-type fertilizers. This is mostly due to: (i) the application of new agricultural technologies such as fertigation and hydroponics, and the increasing use of greenhouses; (ii) the increase in the cost of land and the scarcity of water, which has forced farmers to improve their yields and reduce water use; and (iii) the increase in demand for higher quality crops, such as fruits and vegetables.

Over the last ten years, the compound annual growth rate for vegetable production per capita was 3% while the compound annual growth rate for the world population was closer to 1%.

Worldwide scarcity of water and arable land drives the development of new agricultural techniques to maximize the use of these resources. Irrigation has grown at an average annual rate of 1% during the last 20 years (a pace similar to population growth). However, microirrigation has grown at 10% per year over the same period. Microirrigation systems, which include drip irrigation and micro-sprinklers, are the most efficient forms of technical irrigation. These applications require fully water-soluble plant nutrients. Our nitrate-based specialty plant nutrients are fully soluble in water and provide nitrogen in nitric form, which helps crops absorb these nutrients faster than they absorb urea- or ammonium-based fertilizers, facilitating a more efficient application of nutrients to the plant and thereby increasing the crop’s yield and improving its quality.

| 29 |

The ratio of microirrigation to total irrigated hectares in Asia is approximately 3%, the lowest ratio of any region in the world. This represents a high potential for microirrigation, which is reflected in the high growth rates in Asia in recent years.

Potassium nitrate in China is an important market, although currently its demand is largely fulfilled by domestic producers. Demand totals approximately 400,000 to 420,000 metric tons, of which approximately 130,000 is related to the tobacco industry and approximately 120,000 is related to the horticulture business. Of the total, between 20,000 and 30,000 metric tons are imports.

Specialty Plant Nutrition: Our Products

Potassium nitrate, sodium potassium nitrate and specialty blends are higher margin products derived from, or consisting of, sodium nitrate, and they are all produced in crystallized or prilled form. Specialty blends are produced using our own specialty plant nutrients and other components at blending plants operated by us or our affiliates and related companies in Chile, the United States, Mexico, the United Arab Emirates, South Africa, Turkey, China, India, Thailand, Brazil, Spain, the Netherlands and Peru.

The following table shows our sales volumes of and revenues from specialty plant nutrients for 2017, 2016 and 2015:

|  | 2017 |  |  | 2016 |  |  | 2015 |

Depending on the systems used to apply specialty nutrients, fertilizers can be classified as specialty field fertilizers or water-soluble fertilizers.

Specialty field fertilizers are applied directly to the soil, manually or in a mechanized fashion. Their high solubility levels, lack of chlorine and absence of acidic reactions make them particularly advantageous for tobacco, potatoes, coffee, cotton and a wide range of fruits and vegetables.

Water-soluble fertilizers are specialty nutrients that are delivered to the crops using modern irrigation systems. As these systems feature refined technology, the products used in them must be highly soluble, rich in nutrients, free of impurities and insoluble substances, and with a low salinity index. The leading nutrient in this segment is potassium nitrate, whose optimal balance of nitric nitrogen and chlorine-free potassium (the two macronutrients most needed by plants) make it an indispensable source of nutrition for crops that use modern irrigation systems.

Potassium nitrate is widely known to be a vital component in foliar feeding applications, where usage is recommended in order to stave off nutritional deficiencies before the first symptoms appear, correct any deficiencies that arise and prevent physiological stress. This nutrient also helps promote a suitable balance between fruit production and/or growth, and plant development, particularly in crops with physiological disorders.

Foliar feeding with potassium nitrate can have beneficial effects:

| · | when soil chemistry limits nutrient solubility and availability (pH, organic matter, type and percentage of clay);

| · | when nutrient absorption through the roots is limited as a result of conditions that hamper root growth (temperature, moisture, oxygen and loss of soil structure);

| 30 |

| · | when the plant’s local internal demand may surpass real internal nutrient redistribution capacity, leaving the demand unsatisfied;

| · | when nutrient mobility is limited, when plants flower before the leaf growth phase, imposing limiting factors on xylem nutrient transport and

| · | to achieve rapid recovery from leaf stress caused by climatic conditions, soil conditions and irrigation management.

Another benefit of our potassium nitrate is that, according to a 2014 study by the consulting firm Arthur D. Little Benelux, our production process generates up to 40% less greenhouse gases compared to other major potassium nitrate producers in the world.

SQM has consolidated a product portfolio of over 200 specialty fertilizer blends, including top brands such as UltrasolTM, for fertigation; QropTM, for application to the soil; SpeedfolTM, for foliar feeding and AllganicTM for organic crops.

QropTMKS was added to our portfolio of specialty field fertilizers in 2015. This product was developed by our research and development team and is an improvement to existing products. It is more physically stable and is not required to be transported as hazardous cargo, which means it can be sold in other markets.

During 2017 we worked on the restructuring of the Qrop products portfolio: chlorine-free line for direct application to the soil with a variety of specialized formulas and unique mixtures, which make these products highly accurate and quickly available for the plant.

Specialty Plant Nutrition: Marketing and Customers

In 2017, we sold our specialty plant nutrients in approximately 99 countries and to more than 700 customers. One customer represented more than 10% of our specialty plant nutrition revenues during 2017, representing approximately 25% of our total specialty plant nutrition revenues, and our ten largest customers accounted in the aggregate for approximately 50% of revenues during that period. No supplier accounted for more than 10% of the costs of sales for this business line.

The table below shows the geographical breakdown of our revenues:

Revenues breakdown |  | 2017 |  |  | 2016 |  |  | 2015 |
North America |  |  | 33 | % |  |  | 33 | % |  |  | 33 | %
Europe |  |  | 25 | % |  |  | 18 | % |  |  | 22 | %
Central and South America |  |  | 10 | % |  |  | 11 | % |  |  | 28 | %
Asia and Others |  |  | 31 | % |  |  | 37 | % |  |  | 16 | %

We sell our specialty plant nutrition products outside Chile mainly through our own worldwide network of representative offices and through our distribution affiliates.

We maintain inventory of our specialty plant nutrients in our commercial offices in the main markets of the Americas, Asia, Europe, the Middle East and Africa in order to facilitate prompt deliveries to customers. In addition, we sell specialty plant nutrients directly to some of our large customers. Sales are made pursuant to spot purchase orders and short-term contracts.

As part of our marketing strategy, we provide technical and agronomical assistance and support to our clients. We have specific knowledge resulting from extensive research and numerous studies conducted by our agronomical teams in close contact with producers throughout the world. The solid agronomical knowledge is key for the development of specific formulas and hydroponic and fertirrigation nutritional plans, which allows us to provide expert advice for producing crops that meet high quality standards for the most efficient markets and in the most environmentally challenging conditions.

| 31 |

By working closely with our customers, we are able to identify their needs for new products and a possible existence of higher-value-added markets. Our specialty plant nutrients are used on a wide variety of crops, particularly value-added crops, where the use of our products enables our customers to increase yields and achieve a premium price for their own products.

Our customers are located in both the northern and southern hemispheres. Consequently, we do not believe there are any seasonal or cyclical factors that can materially affect the sales of our specialty plant nutrients.

Specialty Plant Nutrition: Joint Ventures and Agreements

Consistent with our business strategy, we regularly evaluate opportunities to expand in our current core businesses, including our specialty plant nutrition business, or within new businesses in which we believe we may have sustainable competitive advantages. We evaluate potential acquisitions, joint ventures and alliances with companies both within and outside of Chile, including in other emerging markets.

In May 2008, we signed a joint venture agreement with Migao for the production and distribution of specialty plant nutrients in China. Through the joint venture, we constructed a potassium nitrate plant with a production capacity of 40,000 metric tons per year. The plant began operating in January 2011.

In May 2009, our subsidiary Soquimich European Holdings entered into an agreement with Coromandel Fertilizers Ltd. to create a joint venture for the production and distribution of water soluble fertilizers in India. The agreement established a 50⁄50 joint venture. As part of the agreement, a new 15,000 metric ton facility was constructed in the city of Kakinada to produce water soluble NPK grade fertilizers. This new facility began operating in January 2012.

In December 2009, we signed an agreement with the French Roullier Group to form the joint venture SQM Vitas. This agreement joins two of the largest companies in the businesses of specialty plant nutrition, specialty animal nutrition and professional hygiene. Peru, Brazil and Dubai are the main focus markets of this joint venture. As part of the agreement, our phosphate plant located in Dubai became part of this joint venture.

Between 2010 and 2012, we continued to expand our production capacity of potassium products in our operations in the Salar de Atacama. In 2011, we completed the construction of a new potassium nitrate facility in Coya Sur, increasing our overall production capacity of potassium nitrate by 300,000 metric tons.

In 2012, SQM Vitas started the construction of new plants in Brazil (Candeias), Peru and South Africa (Durban) for the production of water soluble fertilizers containing different relative amounts of nitrogen, phosphorus and potassium, and at times, smaller amounts of other chemicals. The Candeias Industrial Complex plant in Brazil began operating in March 2012 and has a production capacity of 25,000 metric tons per year.

In 2013, the operations of SQM Vitas in Spain began with a water soluble NPK fertilizer plant that has a production capacity of 15,000 metric tons per year. In 2016 this operation became fully controlled by SQM.

In 2015, an asset transfer agreement, that was signed in December 2014 between Plantacote BV and Plantacote NV, entered into effect. As a result of this agreement, the business and Plantacote® brand were transferred to the new company Plantacote NV, but with no changes to the business or the Controlled Release Fertilizer project. SQM continues to hold a 50% ownership stake in the company.

| 32 |

In 2015, SQM Vitas South Africa, was acquired by Roulliers. As a result, Roullier manages the operations, and the production facilities are owned by SQM.

In 2016, we began operating soluble specialty plant nutrient production facilities through our joint ventures in Peru and the Netherlands, and a third facility in Mexico. In addition, a new logistics terminal was opened in the port of Terneuzen in the Netherlands.

In 2017, two new offices started their operations in Imbituba and Sao Paulo, Brazil.

Specialty Plant Nutrition: Fertilizer Sales in Chile

We market specialty plant nutrients in Chile through our subsidiary Soquimich Comercial S.A. (“SQMC”).

SQMC is one of the main players in the Chilean market, offering a wide range of products developed specifically for the crops grown in the country which require specialty plant nutrients.

SQMC sells local products as well as products imported from different countries around the world.

All contracts and agreements between SQMC and its foreign suppliers of fertilizers contain standard and customary commercial terms and conditions. SQMC has been able to obtain adequate supplies of these products with good pricing conditions.

SQMC’s fertilizer sales represented approximately 24% of total fertilizer sales in Chile during 2017. No customer accounted for more than 10% of SQMC’s revenues in 2017. SQMC’s consolidated revenues were approximately US$133 million and US$150 million in 2017 and 2016, respectively.

Specialty Plant Nutrition: Competition

The principal means of competition in the sale of potassium nitrate are product quality, customer service, location, logistics, agronomic expertise and price.

We believe that we are the world’s largest producer of sodium nitrate and potassium nitrate for agricultural use. Our sodium nitrate products compete indirectly with specialty and commodity-type substitutes, which may be used by some customers instead of sodium nitrate depending on the type of soil and crop to which the product will be applied. Such substitute products include calcium nitrate, ammonium nitrate and calcium ammonium nitrate.

In the potassium nitrate market our largest competitor is Haifa Chemicals Ltd. (“Haifa”), in Israel, which is a subsidiary of Trans Resources International Inc. We estimate that sales of potassium nitrate by Haifa accounted for approximately 18% of total world sales during 2017 (excluding sales by Chinese producers to the domestic Chinese market). Haifa Chemicals had production issues during 2017 and is currently operating at its 50% capacity (one plant). Our sales accounted for approximately 54% of global potassium nitrate sales by volume for the period.

ACF, another Chilean producer, mainly oriented to iodine production, has produced potassium nitrate from caliche ore and potassium chloride since 2005. Kemapco, a Jordanian producer owned by Arab Potash, produces potassium nitrate in a plant located close to the Port of Aqaba, Jordan. In addition, there are several potassium nitrate producers in China, the largest of which are Yuantong and Migao. Most of the Chinese production is consumed by the Chinese domestic market.

| 33 |

In Chile, our products mainly compete with imported fertilizer blends that use calcium ammonium nitrate or potassium magnesium sulfate. Our specialty plant nutrients also compete indirectly with lower-priced synthetic commodity-type fertilizers such as ammonia and urea, which are produced by many producers in a highly price-competitive market. Our products compete on the basis of advantages that make them more suitable for certain applications as described above.

Iodine and its Derivatives

We believe that we are the world’s largest producer of iodine. In 2017, our revenues from iodine and iodine derivatives amounted to US$252.1 million, representing 12% of our total revenues in that year. We estimate that our sales accounted for approximately 35% of world iodine sales by volume in 2017.

Iodine: Market

Iodine and iodine derivatives are used in a wide range of medical, agricultural and industrial applications as well as in human and animal nutrition products. Iodine and iodine derivatives are used as raw materials or catalysts in the formulation of products such as X-ray contrast media, biocides, antiseptics and disinfectants, pharmaceutical intermediates, polarizing films for LCD and LED screens, chemicals, organic compounds and pigments. Iodine is also added in the form of potassium iodate or potassium iodide to edible salt to prevent iodine deficiency disorders.

X-ray contrast media is the leading application of iodine, accounting for approximately 23% of demand. Iodine’s high atomic number and density make it ideally suited for this application, as its presence in the body can help to increase contrast between tissues, organs, and blood vessels with similar X-ray densities. Other applications include pharmaceuticals, which we believe account for 13% of demand; LCD and LED screens, 12%; iodophors and povidone-iodine, 9%; animal nutrition, 8%; fluoride derivatives, 7%; biocides, 5%; nylon, 4%; human nutrition, 3% and other applications, 16%.

During 2017, iodine demand grew at a higher rate than seen in 2016. Although more traditional uses grew at the same rate as during the previous year, new applications in the specialty plastics and carbon energy plants emission control industries resulted in market demand. We estimate that the global market size in 2017 was approximately 35,300 metric tons, with approximately 59% of supply coming from Chilean producers, including us.

Iodine: Our Products

We produce iodine in our Nueva Victoria plant, near Iquique, and our Pedro de Valdivia plant, close to María Elena. We have a total effective production capacity of approximately 11,000 metric tons per year of iodine, including the Iris plant, which is located close to the Nueva Victoria plant.

Through ASG, we produce organic and inorganic iodine derivatives. ASG was established in the mid-1990s and has production plants in the United States, Chile and France. ASG is the world’s leading inorganic and organic iodine derivatives producer.

Consistent with our business strategy, we are constantly working on the development of new applications for our iodine-based products, pursuing a continuing expansion of our businesses and maintaining our market leadership.

We manufacture our iodine and iodine derivatives in accordance with international quality standards and have qualified our iodine facilities and production processes under the ISO-9001:2008 program, providing third party certification of the quality management system and international quality control standards that we have implemented.

| 34 |

The following table shows our total sales volumes and revenues from iodine and iodine derivatives for 2017, 2016 and 2015:

|  | 2017 |  |  | 2016 |  |  | 2015 |
Sales volumes (Th. MT) |  |  |  |  |  |  |  |  |  |  |  |
Iodine and derivatives |  |  | 12.7 |  |  |  | 10.2 |  |  |  | 9.3 |
Total revenues (in US$ millions) |  |  | 252.1 |  |  |  | 231.1 |  |  |  | 262.6 |

Our revenues increased to US$252.1 million in 2017 from US$231.1 million in 2016. This increase was primarily attributable to the increase in iodine sales volume during 2017. Average iodine prices were more than 12% lower in 2017 than in 2016. Our sales volumes increased 24% in 2017, outpacing global iodine demand growth.

Iodine: Marketing and Customers

In 2017, we sold our iodine products in approximately 52 countries to approximately 287 customers, and most of our sales were exports. Three customers each accounted for more than 10% of our iodine revenues in 2017. These three customers accounted for approximately 43% of revenues, and our ten largest customers accounted in the aggregate for approximately 77% of revenues. No supplier accounted for more than 10% of the cost of sales of this business line.

The following table shows the geographical breakdown of our revenues:

Revenues breakdown |  | 2017 |  |  | 2016 |  |  | 2015 |
North America |  |  | 25 | % |  |  | 25 | % |  |  | 29 | %
Europe |  |  | 31 | % |  |  | 36 | % |  |  | 34 | %
Central and South America |  |  | 0 | % |  |  | 0 | % |  |  | 4 | %
Asia and Others |  |  | 43 | % |  |  | 38 | % |  |  | 33 | %

We sell iodine through our own worldwide network of representative offices and through our sales, support and distribution affiliates. We maintain inventories of iodine at our facilities throughout the world to facilitate prompt delivery to customers. Iodine sales are made pursuant to spot purchase orders or within the framework of supply agreements. Supply agreements generally specify annual minimum and maximum purchase commitments, and prices are adjusted periodically, according to prevailing market prices.

Iodine: Competition

The world’s main iodine producers are based in Chile, Japan and the United States. Iodine is also produced in Russia, Turkmenistan, Azerbaijan, Indonesia and China.

Iodine is produced in Chile using a unique mineral known as caliche ore, whereas in Japan, the United States, Russia, Turkmenistan, Azerbaijan, and Indonesia, producers extract iodine from underground brines that are mainly obtained together with the extraction of natural gas and petroleum. In China, iodine is extracted from seaweed.

Five Chilean companies accounted for approximately 59% of total global sales of iodine in 2017, including SQM, with approximately 35%, and four other producers, accounting for the remaining 24%. The other Chilean producers are: Atacama Chemical S.A. (Cosayach), controlled by the Chilean holding Inverraz S.A.; ACF Minera S.A. owned by the Chilean family Urruticoechea; Algorta Norte S.A., a joint venture between ACF Minera S.A. and Toyota Tsusho; and Atacama Minerals, recently acquired by Chinese company Tewoo.

| 35 |

We estimate that eight Japanese iodine producers accounted for approximately 28% of global iodine sales in 2017, including recycled iodine.

We estimate that iodine producers in the United States (one of which is owned by Toyota Tsusho and another is owned by Ise Chemicals Ltd., both of which are Japanese companies) accounted for nearly 5% of world iodine sales in 2017.

Iodine recycling is a growing trend worldwide. Several producers have recycling facilities where they recover iodine and iodine derivatives from iodine waste streams. Iodine recycling, mainly related to LCD and LED consumption, has reduced during the past year and currently represents approximately 17% of world iodine sales. It is estimated that approximately 70% of total world iodine recycling was done by Japanese iodine producers.

Through ASG or alone, we are also actively participating in the iodine recycling business using iodinated side-streams from a variety of chemical processes in Europe and the United States.

The prices of iodine and iodine derivative products are determined by market conditions. World iodine prices vary depending upon, among other things, the relationship between supply and demand at any given time. Iodine supply varies primarily as a result of the production levels of the iodine producers (including us) and their respective business strategies. Our annual average iodine sales prices decreased to approximately US$20 per kilogram in 2017, continuing the downward trend observed in 2016. However, we believe that 2018 presents better price prospects.

Demand for iodine varies depending upon overall levels of economic activity and the level of demand in the medical, pharmaceutical, industrial and other sectors that are the main users of iodine and iodine-derivative products. Certain substitutes for iodine are available for certain applications, such as antiseptics and disinfectants, which could represent a cost-effective alternative to iodine depending on prevailing prices.

The main factors of competition in the sale of iodine and iodine derivative products are reliability, price, quality, customer service and the price and availability of substitutes. We believe we have competitive advantages compared to other producers due to the size and quality of our mining reserves and the available production capacity. We believe our iodine is competitive with that produced by other manufacturers in certain advanced industrial processes. We also believe we benefit competitively from the long-term relationships we have established with our largest customers.

Lithium and its Derivatives

We believe we are one of the world’s largest producers of lithium carbonate and lithium hydroxide. In 2017, our revenues from lithium sales amounted to US$644.6 million, representing 30% of our total revenues. We estimate that our sales volumes accounted for approximately 23% of the global lithium chemicals sales volumes.

Lithium: Market

The lithium market can be divided into (i) lithium minerals for direct use (in which market SQM does not participate directly), (ii) basic lithium chemicals, which include lithium carbonate and lithium hydroxide (as well as lithium chloride, from which lithium carbonate may be made), and (iii) inorganic and organic lithium derivatives, which include numerous compounds produced from basic lithium chemicals (in which market SQM does not participate directly).

Lithium carbonate and lithium hydroxide are principally used to produce the cathodes for rechargeable batteries, taking advantage of lithium’s extreme electrochemical potential and low density. Batteries are the leading application for lithium, accounting for approximately 59% of total lithium demand, including batteries for electric vehicles, which accounted for approximately 27% of total lithium demand.

| 36 |

There are many other applications both for basic lithium chemicals and lithium derivatives, such as lubricating greases (approximately 9% of total lithium demand), heat-resistant glass (ceramic glass) (approximately 5% of total lithium demand), chips for the ceramics and glaze industry (approximately 4% of total lithium demand), chemicals for air conditioning (approximately 3% of total lithium demand), and many others, including air treatment systems, pharmaceutical synthesis and metal alloys.

Lithium’s main properties, which facilitate its use in this range of applications, are that it:

| · | is the lightest solid element at room temperature;

| · | has a low coefficient of thermal expansion;

| · | has high electrochemical potential and low density and

| · | is the solid with the highest specific heat capacity.

During 2017, lithium chemicals demand increased by approximately 17%, reaching approximately 212,000 metric tons, with close to 37% supplied by Chilean producers. We expect applications related to energy storage to continue driving demand in the coming years.

Lithium: Our Products

We produce lithium carbonate at our Salar del Carmen facilities, near Antofagasta, Chile, from highly concentrated lithium chloride produced in the Salar de Atacama, as a by-product of the potassium chloride production. The annual production capacity of our lithium carbonate plant at the Salar del Carmen is 48,000 metric tons per year. During 2018, we plan to increase our production capacity to 70,000 metric tons per year and start the preparation for the further expansion to 100,000 metric tons per year in 2019. We believe that the technologies we use, together with the high concentrations of lithium and the characteristics of the Salar de Atacama, such as high evaporation rate and concentration of other minerals, allow us to be one of the lowest cost producers worldwide.

We also produce lithium hydroxide at the same plant at the Salar del Carmen, next to the lithium carbonate operation. The lithium hydroxide facility has a production capacity of 6,000 metric tons per year and is one of the largest plants in the world. During 2018, we plan to increase this capacity to 13,500 metric tons per year through increased efficiencies and the construction of a 7,000 metric ton plant.

The following table shows our total sales volumes and revenues from lithium carbonate and its derivatives for 2017, 2016 and 2015:

|  | 2017 |  |  | 2016 |  |  | 2015 |
Sales volumes (Th. MT) |  |  |  |  |  |  |  |  |  |  |  |
Lithium and derivatives |  |  | 49.7 |  |  |  | 49.7 |  |  |  | 38.7 |
Total revenues (in US$ millions) |  |  | 644.6 |  |  |  | 514.6 |  |  |  | 223.0 |

Our revenues in 2017 were US$644.6 million, a 25% increase from US$514.6 million in 2016, due to significantly higher prices during the year. The average price for 2017 was approximately 25% higher than the average price in 2016, as global demand growth outpaced supply growth.

| 37 |

Lithium: Marketing and Customers

In 2017, we sold our lithium products in approximately 42 countries to approximately 198 customers, and most of our sales were to customers outside of Chile. Two customers each accounted for more than 10% of our lithium revenues in 2017, accounting for approximately 22% of our lithium revenues. Our ten largest customers accounted in the aggregate for approximately 68% of revenues. Only one supplier accounted for over 10% of the cost of sales of this business line, accounting for approximately 14% of the cost of sales.

The following table shows the geographical breakdown of our revenues:

Revenues breakdown |  | 2017 |  |  | 2016 |  |  | 2015 |
North America |  |  | 7 | % |  |  | 8 | % |  |  | 11 | %
Europe |  |  | 14 | % |  |  | 19 | % |  |  | 21 | %
Central and South America |  |  | 1 | % |  |  | 1 | % |  |  | 1 | %
Asia and Others |  |  | 79 | % |  |  | 73 | % |  |  | 67 | %

We sell lithium carbonate and lithium hydroxide through our own worldwide network of representative offices and through our sales, support and distribution affiliates. We maintain inventories of these products at our facilities throughout the world to facilitate prompt delivery to customers. Sales of lithium carbonate and lithium hydroxide are made pursuant to spot purchase orders or within the framework of supply agreements. Supply agreements generally specify annual minimum and maximum purchase commitments, and prices are adjusted periodically, according to prevailing market prices.

Lithium: Competition

Lithium is produced mainly from two sources: (i) concentrated brines and (ii) minerals. During 2017, the main lithium brines producers were Chile, Argentina and China, while the main lithium mineral producers were Australia and China. With total sales of approximately 49,700 metric tons of lithium carbonate equivalent (LCE), SQM’s market share of lithium chemicals was approximately 23% in 2017. One of our main competitors is Albemarle Corporation (“Albemarle”), which produces lithium carbonate and lithium chloride in Chile and the United States, along with lithium derivatives in the United States, Germany, Taiwan and China, with a market share of approximately 16%. Albemarle also owns 49% of Talison Lithium Pty Ltd. (“Talison”), an Australian company, that is the largest producer of concentrated lithium minerals in the world, based in Western Australia. The remaining 51% of Talison is owned by Sichuan Tianqi Lithium Industries (“Tianqi”), a Chinese company producing basic lithium chemicals in China from concentrated lithium minerals. Talison sells a part of its concentrated lithium mineral production to the direct use market, but most of its production, representing approximately 27% of total lithium chemical demand, is converted into basic lithium chemicals in China by Tianqi and Albemarle.

Another important competitor is FMC Corporation (“FMC”), with an estimated market share of approximately 9%. FMC has production facilities in Argentina through Minera del Altiplano S.A., where it produces lithium chloride and lithium carbonate. In addition, FMC produces lithium derivatives in the United States and in the United Kingdom. Orocobre Ltd. is also based in Argentina and produces lithium carbonate, reaching a market share of approximately 5%.

During 2017, two companies started their production of concentrated lithium minerals in Western Australia, which are then converted into lithium chemicals in China. Together, these companies sell approximately 11% of the total lithium demand in 2017. These companies are Neometals Ltd. with operations in Mt. Marion, one of the owners is Jiangxi Ganfeng Lithium Co. (“Ganfeng”), a Chinese company producing basic chemicals and lithium derivatives, and Galaxy Resources Ltd., with operations in Mt. Cattlin. In addition, there were at least ten other companies producing lithium in China from brines or minerals, which together represented about 9% of the global market in 2017.

| 38 |

We believe that lithium production will increase in the near future, balancing the explosive growth in demand. A number of new projects to develop lithium deposits has been announced recently. Some of these projects are already in the advanced stages of development and others could materialize in the medium term.

Potassium

We produce potassium chloride and potassium sulfate by extracting brines from the Salar de Atacama that are rich in potassium chloride and other salts.

Potassium is one of the three macronutrients that a plant needs to develop. Although potassium does not form part of a plant’s structure, it is essential to the development of its basic functions. Potassium chloride is the most commonly used potassium-based fertilizer. It is used to fertilize crops that can tolerate relatively high levels of chloride, and to fertilize crops that are grown under conditions with sufficient rainfall or irrigation practices that prevent chloride from accumulating to excess levels in the rooting systems of the plant.

Some benefits that may be obtained through the use of potassium are:

| · | increased yield and quality;

| · | increased production of proteins;

| · | increased photosynthesis;

| · | intensified transport and storage of assimilates;

| · | prolonged and more intense assimilation period;

| · | improved water efficiency;

| · | regulated opening and closure of stomata; and

| · | synthesis of lycopene.

Potassium chloride is also an important component for our specialty plant nutrition product line, where it is used as a raw material to produce potassium nitrate.

Since 2009, our effective end product capacity has increased to over 2 million metric tons per year, granting us improved flexibility and market coverage.

In 2017, our potassium chloride and potassium sulfate revenues amounted to US$379.3 million, representing 18% of our total revenues and a 6% decrease compared to 2016, as a result of reduced sales volumes.

Potassium: Market

During the last decade, growth in demand for potassium chloride, and for fertilizers in general, has been driven by several key factors, such as a growing world population, higher demand for protein-based diets and less arable land. All of these factors contribute to fertilizer demand growth as a result of efforts to maximize crop yields and use resources more efficiently. For the last ten years, the compound annual growth for the global potassium chloride market was approximately 1-2%. We estimate that demand totaled approximately 63 million metric tons in 2017, an increase from 59 million tons in 2016.

According to studies prepared by the International Fertilizer Industry Association, cereals account for approximately 45% of world potassium consumption, including corn (14%), rice (13%) and wheat (3%). Oilseeds, predominantly soybeans and palm oil, represent approximately 16% of total potassium demand. Fruits and vegetables account for approximately 22% of world potassium demand, and sugar crops account for close to 7%.

| 39 |

Potassium: Our Products

Potassium chloride differs from our specialty plant nutrition products because it is a commodity fertilizer and contains chloride. We offer potassium chloride in two grades: standard and compacted. Potassium sulfate is considered a specialty fertilizer and we offer this product in soluble grades.

The following table shows our sales volumes of and revenues from potassium chloride and potassium sulfate for 2017, 2016 and 2015:

|  | 2017 |  |  | 2016 |  |  | 2015 |
Sales volumes (Th. MT) |  |  |  |  |  |  |  |  |  |  |  |
Potassium chloride and potassium sulfate |  |  | 1,344.3 |  |  |  | 1,534.7 |  |  |  | 1,241.8 |
Total revenues (in US$ millions) |  |  | 379.3 |  |  |  | 403.3 |  |  |  | 430.6 |

Potassium: Marketing and Customers

In 2017, we sold potassium chloride and potassium sulfate to approximately 530 customers in over 80 countries. There were two individual customers that each accounted for more than 10% of our revenues of potassium chloride and potassium sulfate in 2017, totaling approximately 21% of the revenues of potassium chloride and potassium sulfate during this period. We estimate that our ten largest customers accounted in the aggregate for approximately 55% of such revenues. One supplier accounted for more than 10% of the cost of sales of this business line, accounting for approximately 16% of the cost of sales for the business line.

The following table shows the geographical breakdown of our revenues:

Revenues breakdown |  | 2017 |  |  | 2016 |  |  | 2015 |
North America |  |  | 18 | % |  |  | 20 | % |  |  | 22 | %
Europe |  |  | 19 | % |  |  | 20 | % |  |  | 12 | %
Central and South America |  |  | 38 | % |  |  | 38 | % |  |  | 42 | %
Asia and Others |  |  | 25 | % |  |  | 22 | % |  |  | 24 | %

Potassium: Competition

We estimate that we accounted for less than 3% of global sales of potassium chloride in 2017. Our main competitors are Nutrien (formerly PCS), Uralkali, Belaruskali and Mosaic. We estimate that in 2017, PCS accounted for approximately 20% of global sales, Uralkali accounted for approximately 15% of global sales, Belaruskali accounted for approximately 14% of global sales and Mosaic accounted for approximately 14% of global sales.

In the potassium sulfate market, we have several competitors, of which the most important are K+S KALI GmbH (Germany), Tessenderlo Chemie (Belgium) and Great Salt Lake Minerals Corp. (United States). We estimate that these three producers account for approximately 30% of the worldwide production of potassium sulfate. SQM accounts for less than 2% of global production.

Industrial Chemicals

In addition to producing sodium and potassium nitrate for agricultural applications, we produce different grades of these products for industrial applications. The different grades differ mainly in their chemical purity. We enjoy certain operational flexibility producing industrial nitrates, because they are produced from the same process as their equivalent agricultural grades, needing only an additional step of purification. We may, with certain constraints, shift production from one grade to the other depending on market conditions. This flexibility allows us to maximize yields and to reduce commercial risk.

| 40 |

In addition to producing industrial nitrates, we produce, market and sell industrial-grade potassium chloride.

In 2017, our revenues from industrial chemicals were US$135.6 million, representing approximately 6% of our total revenues for that year.

Industrial Chemicals: Market

Industrial sodium and potassium nitrates are used in a wide range of industrial applications, including the production of glass, ceramics, explosives, charcoal briquettes, metal treatments together with various chemical processes.

In addition, this product line has also experienced growth from the use of industrial nitrates as thermal storage in concentrated solar power plants (commonly known as “CSP”). Solar salts for this specific application contain a blend of 60% sodium nitrate and 40% potassium nitrate by weight ratio used as a storage and heat transfer medium. Unlike traditional photovoltaic plants, these new plants use a “thermal battery” that contains molten sodium nitrate and potassium nitrate, which store the heat collected during the day. The salts are heated up during the day, while the plants are operating under direct sunlight, and at night they release the solar energy that they have captured, allowing the plants to operate even during hours of darkness. Depending on the power plant technology, solar salts are also used as a heat transfer fluid in the plant system and thereby make CSP plants even more efficient, increasing their output and reducing the Levelized Cost of Electricity (LCOE).

Experts believe that CSP plays a critical role in electricity grid stabilization and manageability due to its inherent large scale storage capability. Nevertheless, such large installations are capital intensive and are strongly influenced by the generation mix in each country. Therefore, fluctuations in solar salts demand are unavoidable in terms of quantity and timing. In 2017, we supplied CSP projects in South Africa, Morocco, Kuwait and Israel totaling over 88,000 metric tons. In 2018 we should further supply a CSP plant in Kuwait and another one in South Africa, while negotiating the supply to other very large installations in Dubai, Morocco and Chile.

As reported by the International Energy Agency (IEA), in 2016, global total cumulative electricity capacity grew by 4% and reached a total of 6,650 GW. Renewables provided almost two-thirds of this growth with a record addition of 165 GW, 6% higher compared to 2015. Renewables remain the largest source of cumulative capacity at 2,135 GW and this trend is expected to continue in the next years to come. Under these conditions, energy storage is becoming of critical importance and its role in increasing the electrical grid stability and dispatchability of the electricity generated by renewable technologies is receiving a growing interest from utilities, grid operators as well as governments and lenders.

According to the IEA, CSP capacity is expected to grow by over 5 GW over 2017-2022, with new deployment moving into nascent markets, most notably Chile, Kuwait, Morocco, South Africa and the United Arab Emirates, as well as continued growth in China. Projects with larger storage capacity and decreasing investment costs for experienced developers mark the trend for the coming five years.

We are also experiencing a growing interest in using solar salts in thermal storage solutions not related to CSP technology. Due to their proven performance, solar salts are being tested in industrial heat processes and heat waste solutions. These new applications may open new opportunities to the solar salts uses in the near future.

Industrial-grade potassium chloride is used as an additive in oil drilling as well as in food processing, among other applications.

Industrial Chemicals: Our Products

The following table shows our sales volumes of industrial chemicals and total revenues for 2017, 2016 and 2015:

|  | 2017 |  |  | 2016 |  |  | 2015 |
Sales volumes (Th. MT) |  |  |  |  |  |  |  |  |  |  |  |
Industrial chemicals |  |  | 167.6 |  |  |  | 128.9 |  |  |  | 126.1 |
Total revenues (in US$ millions) |  |  | 135.6 |  |  |  | 104.1 |  |  |  | 97.6 |

Revenues for industrial chemicals increased from US$104.1 million in 2016 to US$135.6 million in 2017, as a result of higher sales volumes in this business line.

Industrial Chemicals: Marketing and Customers

We sold our industrial nitrate products in approximately 55 countries in 2017 to approximately 296 customers. Four customers accounted for more than 10% of our revenues of industrial chemicals in 2017, accounting for approximately 57%, and our ten largest customers accounted in the aggregate for approximately 68% of such revenues. No supplier accounted for more than 10% of the cost of sales of this business line.

The following table shows the geographical breakdown of our revenues for 2017, 2016 and 2015:

Revenues breakdown |  | 2017 |  |  | 2016 |  |  | 2015 |
North America |  |  | 19 | % |  |  | 24 | % |  |  | 31 | %
Europe |  |  | 21 | % |  |  | 14 | % |  |  | 15 | %
Central and South America |  |  | 7 | % |  |  | 9 | % |  |  | 11 | %
Asia and Others |  |  | 53 | % |  |  | 54 | % |  |  | 43 | %

We sell our industrial chemical products mainly through our own worldwide network of representative offices and through our sales and distribution affiliates. We maintain inventories of our different grades of sodium nitrate and potassium nitrate products at our facilities in Europe, North America, South Africa, Asia and South America to achieve prompt deliveries to customers. Our Research and Development department, together with our foreign affiliates, provides technical support to our customers and continuously works with them to develop new products or applications for our products.

Industrial Chemicals: Competition

We believe we are one of the leading producers of sodium nitrate and potassium nitrate for industrial uses. In the case of industrial sodium nitrate, we estimate that our sales represented close to 37% of world demand in 2017 (excluding internal demand for China and India, for which we believe reliable estimates are not available). Our competitors are mainly based in Europe and Asia, producing sodium nitrate as a by-product of other production processes. In refined grade sodium nitrate, BASF AG (“BASF”), a German corporation and several producers in China and Eastern Europe are highly competitive in the European and Asian markets. Our industrial sodium nitrate products also compete indirectly with substitute chemicals, including sodium carbonate, sodium sulfate, calcium nitrate and ammonium nitrate, which may be used in certain applications instead of sodium nitrate and are available from a large number of producers worldwide.

Our main competitor in the industrial potassium nitrate business is Haifa Chemicals (“Haifa”), which we estimate had a market share of 26%. We estimate that our market share was approximately 30% for 2017.

| 42 |

In the solar salts business, we believe we have been the market leader since we started selling to commercial projects in 2007. Our competitors include Haifa, which is a potassium nitrate supplier, and BASF, which is a sodium nitrate supplier.

Producers compete in the market for industrial sodium and potassium nitrate based on reliability, product quality, price and customer service. We believe that we are a low cost producer of both products and are able to produce high quality products.

In the industrial potassium chloride market, we are a relatively small producer, mainly supplying regional needs.

Other Products

A large part of our other revenue is related to fertilizer trading, usually commodities. These fertilizers are traded in large volumes worldwide. We have developed a trade, supply and inventory management business that allows us to respond quickly and effectively to the changing fertilizer market in which we operate and profit on these trades.

Production Process

Our integrated production process can be classified according to our natural resources:

| · | caliche ore deposits, which contain nitrates, iodine and potassium; and

| · | brines from the Salar de Atacama, which contain potassium, lithium, sulfate, boron and magnesium.

Caliche Ore Deposits

Caliche ore deposits are located in northern Chile. During 2017, our mining operations concentrated in the first Region where we worked in the mining sector Tente en el Aire and continued with the exploration of the mining sector Nueva Victoria Oeste. We believe that a concentrated mining operation allows us to capture operating synergies that will increase efficiency and reduce costs. Mining operations at the Pampa Blanca site, the El Toco mine (which is part of the María Elena site) and the Pedro de Valdivia site were suspended in March 2010, November 2013 and November 2015, respectively, in an effort to optimize our production facilities with lower production costs.

Caliche ore is found under a layer of barren overburden in seams with variable thickness from twenty centimeters to four meters, and with the overburden varying in thickness between half a meter and two meters.

Before proper mining begins, the exploration stage is carried out, including complete geological reconnaissance, sampling and drilling caliche ore to determine the quality and characteristics of each deposit. Drill-hole samples are properly identified and tested at our chemical laboratories. With the exploration information on a closed grid pattern of drill holes, the ore evaluation stage provides information for mine planning purposes. Mine planning is done on a long-term basis (ten years), medium-term basis (three years) and short-term basis (one year). Once all of this information has been compiled, detailed planning for the exploitation of the mine takes place.

The mining process generally begins with bulldozers first breaking and then removing the overburden in the mining area. This process is followed by an inspection and review of the drill holes before production drilling and blasting occurs to break the caliche seams. Front-end loaders load the ore onto off-road trucks, which take it to the leaching heaps to be processed.

| 43 |

During 2017, SQM ran various tests with a continuous mining equipment replacing the drilling and blasting process and obtaining a smaller ore size (under 6 inches) that allows a better metallurgical recovery. The tests will conclude in 2018.

The run of mine ore is loaded in heaps and leached with water to produce concentrated solutions containing iodine, nitrate and potassium. These solutions are then sent to plants where iodine is extracted through both solvent-extraction and blow out processes. The remaining solutions are subsequently sent to solar evaporation ponds where the solutions are evaporated and salts rich in nitrate and potassium are produced. These concentrated salts are then sent to Coya Sur where they are used to produce potassium nitrate.

During 2017, the Pedro de Valdivia and María Elena sites generated solutions produced by leaching the mine tailings. These solutions are treated at the iodide plants at Pedro de Valdivia and María Elena. The iodide that is produced at the María Elena plant is subsequently sent to Pedro de Valdivia in order to produce prilled iodine. After iodide is obtained at both plants, the remaining solutions, which are rich in nitrate and potassium, are sent to the solar evaporation ponds at Coya Sur in order to be used in the production of potassium nitrate.

Caliche Ore-Derived Products

Caliche ore-derived products are: sodium nitrate, potassium nitrate, sodium potassium nitrate and iodine.

Sodium Nitrate

During 2017, sodium nitrate for both agricultural and industrial applications was produced by inventory generated at the Pedro de Valdivia facility and subsequently processed at the Coya Sur plants. The production at the Pedro de Valdivia facility, until November 2015, generated approximately 700,000 tons of inventory. As of December 2017, we had approximately 277,000 tons of crystallized sodium nitrate in inventory, which will provide us with enough sodium nitrate to produce finished nitrates for approximately two years. For subsequent production, we are developing the project of adapting the available crystallization plants at Coya Sur to be able to produce sodium nitrate using nitrate salts from our Nueva Victoria facility.

Crystallized sodium nitrate is an intermediate product that is subsequently processed further at the Coya Sur production plants to produce sodium nitrate, potassium nitrate and sodium potassium nitrate in different chemical and physical qualities, including crystallized and prilled products. Finally, the products are transported by truck to our port facilities in Tocopilla for shipping to customers and distributors worldwide.

Potassium Nitrate

Potassium nitrate is produced at our Coya Sur facility using a production process developed in-house. The brines generated by the leaching processes at Pedro de Valdivia and María Elena are pumped to Coya Sur’s solar evaporation ponds for a nitrate concentration process. After the nitrate concentration process, the brine is pumped to a conversion plant where potassium salts from the Salar de Atacama and nitrate and potassium salts produced at Nueva Victoria or Coya Sur, are added. A chemical reaction begins, transforming sodium nitrate into potassium nitrate and discarding formed sodium chloride. This brine is pumped to a crystallization plant, which crystallizes the potassium nitrate by cooling it at atmospheric pressure, and separating it from the liquid by centrifuge.

Our current potassium nitrate production capacity at Coya Sur is approximately 1,300,000 metric tons per year. Since the end of 2013, we have been working with external advisors to implement the “lean” method of manufacturing in our potassium nitrate plants. We achieved complete implementation of this method of manufacturing during 2015. The improvements we have achieved have enabled us to reduce costs, improve energy consumption, increase the production of potassium nitrate and decrease our accident rates. This method is based on increasing the involvement of our workers in decision-making, and strengthening the leadership of our production supervisors. The goal is to identify opportunities to improve the production process and reduce waste on an ongoing basis.

| 44 |

During 2017, new operational improvements have been achieved by significantly integrating the production process of the Coya Sur facilities, allowing new increases in production capacity without major investments and improving the use of raw materials from the Salar de Atacama and Nueva Victoria.

Sodium Potassium Nitrate

Sodium potassium nitrate is a mixture of approximately two parts sodium nitrate per one part potassium nitrate. We produce sodium potassium nitrate at our Coya Sur prilling facilities using standard, non-patented production methods we have developed. Crystallized sodium nitrate is supplied together with the crystallized potassium nitrate to the prilling plant where it is mixed producing sodium potassium nitrate, which is then melted and prilled. The prilled sodium potassium nitrate is transported to Tocopilla for bulk shipment to customers.

The production process for sodium potassium nitrate is basically the same as that for sodium nitrate and potassium nitrate. With certain production restraints and following market conditions, we may supply sodium nitrate, potassium nitrate or sodium potassium nitrate, either in prilled or crystallized form.

The sodium nitrate and potassium nitrate produced at Coya Sur are transported to Tocopilla for shipping and delivery to customers and distributors. All potassium nitrate produced in crystallized or prilled form at Coya Sur has been certified by TÜV-Rheiland under the quality standard ISO 9001:2008.

Iodine and Iodine Derivatives

During 2017, we produced iodine at our facilities at Nueva Victoria (including the Iris facility), Pedro de Valdivia and María Elena. Iodine is extracted from solutions produced by leaching caliche ore.

As in the case of nitrates, the process of extracting iodine from the caliche ore is well established, but variations in the iodine and other chemical contents of the treated ore and other operating parameters require a high level of know-how to manage the process effectively and efficiently.

The solutions resulting from the leaching of caliche carry iodine in iodate form. Part of the iodate solution is reduced to iodide using sulfur dioxide, which is produced by combusting (burning) sulfur. The resulting iodide is combined with the rest of the untreated iodate solution to release elemental iodine in low concentrations. The iodine is then extracted from the aqueous solutions and concentrated in iodide form using a solvent extraction and stripping plant in the Pedro de Valdivia and Nueva Victoria facilities and using a blow out plant in Iris. The concentrated iodide is oxidized to metallic iodine, which is then refined through a smelting process and prilled. We have obtained patents in the United States and Chile (Chilean patent number 47,080) for our iodine prilling process.

Prilled iodine is tested for quality control purposes, using international standard procedures that we have implemented. It is then packed in 20 to 50 kilogram drums or 350 to 700 kilogram maxibags and transported by truck to Antofagasta, Mejillones, or Iquique for export. Our iodine and iodine derivatives production facilities have qualified under the ISO-9001:2008 program, providing third-party certification—by TÜV-Rheiland—of the quality management system. The last recertification process was approved in February 2011. Iodine from the Iris plant was certified under ISO-9001:2008 in April 2012.

| 45 |

Our total iodine production in 2017 was 9,696 metric tons: 7,476 metric tons from Nueva Victoria, 1,328 metric tons from Iris, 851 metric tons from Pedro de Valdivia, and 41 metric tons from María Elena. Nueva Victoria is also equipped to toll iodine from iodide delivered from our other facilities. We have the flexibility to adjust our production according to market conditions. Following the production facility restructuring at Pedro de Valdivia and Nueva Victoria, our total current effective production capacity at our iodine production plants is approximately 11,000 metric tons per year. We are currently developing a project to expand the production capacity of iodide and iodine in Nueva Victoria to increase our total effective production capacity to 14,000 metric tons per year.

We use a portion of the iodine we produce to manufacture inorganic iodine derivatives, which are intermediate products used for manufacturing agricultural and nutritional applications, at facilities located near Santiago, Chile. We also produce inorganic and organic iodine derivative products together with Ajay, which purchases iodine from us. In the past, we have primarily sold our iodine derivative products in South America, Africa and Asia, while Ajay and its affiliates have primarily sold their iodine derivative products in North America and Europe.

In September 2010, CONAMA, currently known as the Environmental Evaluation Service, approved the environmental study of our Pampa Hermosa project in the Tarapacá Region of Chile. This environmental permit allows for an increase in the production capacity of our Nueva Victoria operations to 11,000 metric tons of iodine per year and to produce up to 1.2 million metric tons of crystallized nitrates, mine up to 37 million metric tons of caliche per year and use new water rights of up to 570.8 liters per second. In recent years, we have made investments in order to increase the water capacity in the Nueva Victoria operations from two water sources approved by the environmental study of Pampa Hermosa, expand the capacity of solar evaporation ponds, and implement new areas of mining and collection of solutions. Our current production capacity at Nueva Victoria is approximately 10,000 metric tons per year of iodine (including the Iris operations) and 900,000 metric tons per year of nitrates. Additional expansions may be done from time to time in the future, depending on market conditions.

Salar de Atacama Brine Deposits

The Salar de Atacama, located approximately 250 kilometers east of Antofagasta, is a salt-encrusted depression in the Atacama Desert, within which lies an underground deposit of brines contained in porous sodium chloride rock fed by an underground inflow from the Andes mountains. Brines are pumped from depths of 1.5 to 60 meters below surface, through a field of wells that are located in the Salar de Atacama, distributed in areas authorized for exploitation, and which contain relatively high concentrations of potassium, lithium, sulfate, boron and other minerals.

The brines are estimated to cover a surface of approximately 2,800 square kilometers and contain commercially exploitable deposits of potassium, lithium, sulfates and boron. Concentrations vary at different locations throughout the Salar de Atacama. Our mining exploitation rights to the Salar de Atacama are pursuant to the Lease Agreement, which expires in 2030. The Lease Agreement permits the CCHEN to establish a total accumulated extraction and sales limit of 180,100 tons of lithium metal (958,672 tons of lithium carbonate equivalent) in the aggregate for all periods. For the year ended December 31, 2017, revenues related to products originating from the Salar de Atacama represented 47% of our consolidated revenues, consisting of revenues from our potassium business line and our lithium and derivatives business line for the period. All of our products originating from the Salar de Atacama are derived from our extraction operations under the Lease Agreement. As of December 31, 2017, only 13 years remain on the term of the Lease Agreement and we had extracted approximately 64% of the total accumulated extraction and sales limit of lithium.

On January 17, 2018, Corfo and our subsidiaries SQM Salar and SQM Potasio S.A. entered into the Corfo Arbitration Agreement, which, among other things, provide for the amendments of the Lease Agreement and the Project Agreement. As part of the agreement to amend the Lease Agreement, Corfo authorized an increase of the production and sales of lithium products produced in the Salar de Atacama up to 349,553 metric tons of lithium metallic equivalent (1,860,670 tons of lithium carbonate equivalent), which is in addition to the approximately 64,816 metric tons of lithium metallic equivalent (345,015 tons of lithium carbonate equivalent) remaining from the originally authorized amount. See “Item 3.D. Risk Factors” and “Item 8.A.7 Legal Proceedings.”

Products Derived from the Salar de Atacama Brines

The products derived from the Salar de Atacama brines are: potassium chloride, potassium sulfate, potassium salts, lithium carbonate, lithium hydroxide, lithium chloride, boric acid and bischofite (magnesium chloride).

Potassium Chloride

We use potassium chloride in the production of potassium nitrate. Production of our own supplies of potassium chloride provides us with substantial raw material cost savings. We also sell potassium chloride to third parties, primarily as a commodity fertilizer.

In order to produce potassium chloride, brines from the Salar de Atacama are pumped to solar evaporation ponds. Evaporation of the water contained in the brine, results in a crystallized mixture of salts with various content levels of potassium, sodium and magnesium. In the first stage of the precipitation, sodium chloride salts are removed; these salts are not used in the production process of other products. After further evaporation, the sodium and potassium salts are harvested and sent for treatment at one of the wet potassium chloride plants where potassium chloride is separated by a grinding, flotation, and filtering process. In the final evaporation stage, salts containing magnesium are harvested and eventually can be treated at one of the cold leach plants where magnesium is removed. Potassium chloride is transported approximately 300 kilometers to our Coya Sur facilities via a dedicated truck transport system, where it is used in the production of potassium nitrate. We sell potassium chloride produced at the Salar de Atacama in excess of our needs to third parties. All of our potassium-related plants in the Salar de Atacama currently have a nominal production capacity in excess of up to 2.6 million metric tons per year. Actual production capacity depends on volume, metallurgical recovery rates and quality of the mining resources pumped from the Salar de Atacama.

The by-products of the potassium chloride production process are (i) solutions remaining after removal of the potassium chloride, which are used to produce lithium carbonate as described below, with the excess amount not required for lithium carbonate production being reinjected into the Salar de Atacama; (ii) sodium chloride, which is similar to the surface material of the Salar de Atacama and is deposited at sites near the production facility and (iii) other salts containing magnesium chloride.

Lithium Carbonate and Lithium Chloride

After the production of potassium chloride, a portion of the solutions remaining is sent to additional solar concentration ponds adjacent to the potassium concentration ponds. At this stage, the solution is concentrated and purified by precipitation to remove impurities it may still contain, including calcium, sulfate, potassium, sodium and magnesium. Next is the process of concentration and purification of the remaining concentrated solution of lithium chloride, which is transported by truck to the Salar del Carmen production facility located near Antofagasta, approximately 230 kilometers from the Salar de Atacama. At this plant, the solution is further purified and treated with sodium carbonate to produce lithium carbonate, which is dried and then, if necessary, compacted and finally packaged for shipment. The production capacity of our lithium carbonate facility is approximately 48,000 metric tons per year. Currently, the necessary investments are being made to reach a production of 70,000 metric tons per year and start the preparation for the further expansion to 100,000 metric tons per year in 2019.

| 47 |

Future production will depend on the actual volumes and quality of the lithium solutions sent by the Salar de Atacama operations, as well as prevailing market conditions. Our future production was also subject to the extraction limit of 180,100 tons of lithium (958,672 tons of lithium carbonate equivalent) in the aggregate for all periods of the Lease Agreement mentioned above which may be increased in the event the Lease Agreement is amended as described above. See “—Salar de Atacama Brine Deposits” and “Item 8.A.7 Legal Proceedings.”

Our lithium carbonate production quality assurance program has been certified by TÜV-Rheiland under ISO 9001:2000 since 2005 and under ISO 9001:2008 since October 2009.

Lithium Hydroxide

Lithium carbonate is sold to customers, and we also use it as a raw material for our lithium hydroxide production, which started operations at the end of 2005. This facility has a production capacity of 6,000 metric tons per year, and is located in the Salar del Carmen, adjacent to our lithium carbonate operations. In 2018, the necessary investments will be made to build a second lithium hydroxide plant, which will have a capacity of 7,000 metric tons per year. In the production process, lithium carbonate is reacted with a lime solution to produce lithium hydroxide brine and calcium carbonate salt, which is filtered and piled in reservoirs. The lithium hydroxide solution is evaporated in a multiple effect evaporator and crystallized to produce the lithium hydroxide, which is filtered, dried and packaged for shipment to customers.

Our lithium hydroxide production quality assurance program has been certified by TÜV-Rheiland under ISO 9001:2000 since 2007 and under ISO 9001:2008 since October 2009.

Potassium Sulfate and Boric Acid

Approximately 12 kilometers northeast of the potassium chloride facilities at the Salar de Atacama, we use the brines from the Salar de Atacama to produce potassium sulfate, potassium chloride (as a by-product of the potassium sulfate process) and, depending on market conditions, boric acid. The plant is located in an area of the Salar de Atacama where high sulfate and potassium concentrations are found in the brines to produce potassium sulfate. The brine is pumped to solar evaporation ponds, where sodium chloride salts are precipitated, harvested and put into piles. After further evaporation, the sulfate and potassium salts precipitate in different concentrations and are harvested and sent for processing to the potassium sulfate plant. Potassium sulfate is produced using flotation, concentration and reaction processes, after which it is crystallized, filtered, dried, classified and packaged for shipment.

Production capacity for the potassium sulfate plant is approximately 340,000 metric tons per year, of which approximately 95,000 metric tons correspond to potassium chloride obtained as a byproduct of the potassium sulfate process. This capacity is part of the total nominal plant capacity of 2.6 million metric tons per year. In our dual plant complex, we may switch, to some extent, between potassium chloride and potassium sulfate production. Part of the pond system in this area is also used to process potassium chloride brines extracted from the low sulfate concentration areas found in the Salar de Atacama. Depending on the conditions for the optimization of the deposit operation and/or market conditions, potassium sulfate production can be modified to produce potassium chloride.

The principal by-products of the production of potassium sulfate are: (i) non-commercial sodium chloride, which is deposited at sites near the production facility and (ii) remaining solutions, which are re-injected into the Salar de Atacama or returned to the evaporation ponds. The principal by-products of the boric acid production process are remaining solutions that are treated with sodium carbonate to neutralize acidity and then are reinjected into the Salar de Atacama.

Raw Materials

The main raw material that we require in the production of nitrate and iodine is caliche ore, which is obtained from our surface mines. The main raw material in the production of potassium chloride, lithium carbonate and potassium sulfate is the brine extracted from our operations at the Salar de Atacama.

Other important raw materials are sodium carbonate (used for lithium carbonate production and for the neutralization of iodine solutions), sulfuric acid, kerosene, anti-caking and anti-dust agents, ammonium nitrate (used for the preparation of explosives in the mining operations), woven bags for packaging our final products, electricity acquired from electric utilities companies, and liquefied natural gas and fuel oil for heat generation. Our raw material costs (excluding caliche ore and salar brines and including energy) represented approximately 14% of our cost of sales in 2017.

We have been connected to the northern power grid in Chile, which currently supplies electricity to most cities and industrial facilities in northern Chile, since April 2000. We have several electricity supply agreements signed with major producers in Chile, which are within the contract terms. Our electricity needs are primarily covered by the Electrical Energy Supply Agreement that we entered into with AES Gener S.A. on December 31, 2012. Pursuant to the terms of the Electrical Energy Supply Agreement, we are required to purchase an amount of electricity that exceeds the amount that we estimate we will need for our operations. The excess amount is sold at marginal cost, which could result in a material loss for us.

For the supply of liquefied natural gas, in 2013 and 2014 we had a contract with Solgas. For 2015, 2016 and 2017, we executed supply contracts with Enel Chile S.A. as with Solgas, primarily to serve our operations at the Salar del Carmen and Coya Sur.

We obtain ammonium nitrate, sulfuric acid, kerosene and soda ash from several large suppliers, mainly in Chile and the United States, under long-term contracts or general agreements, some of which contain provisions for annual revisions of prices, quantities and deliveries. Diesel fuel is obtained under contracts that provide fuel at international market prices.

We believe that all of our contracts and agreements with third-party suppliers with respect to our main raw materials contain standard and customary commercial terms and conditions.

Water Supply

We hold water rights for the supply of surface and subterranean water near our production facilities. The main sources of water for our nitrate and iodine facilities at Pedro de Valdivia, María Elena and Coya Sur are the Loa and San Salvador rivers, which run near our production facilities. Water for our Nueva Victoria and Salar de Atacama facilities is obtained from wells near the production facilities. In addition, we buy water from third parties for our production processes at the Salar del Carmen lithium carbonate and lithium hydroxide plants, and we also purchase potable water from local utility companies. We have not experienced significant difficulties obtaining the necessary water to conduct our operations.

Government Regulations

Regulations in Chile Generally

We are subject to the full range of government regulations and supervision generally applicable to companies engaged in business in Chile, including labor laws, social security laws, public health laws, consumer protection laws, tax laws, environmental laws, free competition laws, and securities laws. These include regulations to ensure sanitary and safety conditions in manufacturing plants.

| 49 |

We conduct our mining operations pursuant to judicial exploration concessions and exploitation concessions granted pursuant to applicable Chilean law. Exploitation concessions essentially grant a perpetual right (with the exception of the Salar de Atacama rights, which have been leased to us until 2030) to conduct mining operations in the areas covered by such concessions, provided that annual concession fees are paid. Exploration concessions permit us to explore for mineral resources on the land covered thereby for a specified period of time, and to subsequently request a corresponding exploitation concession.

Under Law No. 16,319 that created the CCHEN, we have an obligation to the CCHEN regarding the exploitation and sale of lithium from the Salar de Atacama, which prohibits the use of lithium for nuclear fusion. In addition, CCHEN has imposed quotas that limit the total tonnage of lithium authorized to be sold.

We also hold water use rights granted by the respective administrative authorities and which enable us to have a supply of water from rivers or wells near our production facilities sufficient to meet our current operating requirements. See “Item 3.D. Risk Factors—Risks Relating to Chile—Changes in water rights laws and other regulations could affect our operating costs.” The Water Code and related regulations are subject to change, which could have a material adverse impact on our business, financial condition and results of operations.

We operate port facilities at Tocopilla, Chile for the shipment of products and the delivery of raw materials in conformity with maritime concessions, which have been granted by the respective administrative authority. These concessions are normally renewable on application, provided that such facilities are used as authorized and annual concession fees are paid.

In 2005, Law No. 20,026, known as the Law to Establish a Specific Tax on Mining Activity” (Ley que Establece un Impuesto Específico a la Actividad Minera or the “Royalty Law”), established a royalty tax to be applied to mining activities developed in Chile. In 2010, modifications were made to the law and taxes were increased.

In 2012, new modifications to the tax laws were enacted to set the corporate tax rate at 20% for companies like SQM.

On September 29, 2014, Law No. 20,780 was published (the “Tax Reform”), introducing significant changes to the Chilean taxation system and strengthening the powers of the SII to control and prevent tax avoidance. Subsequently, on February 8, 2016, Law No. 20,899 that simplifies the income tax system and modifies other legal tax provisions was published. As a result of these reforms, open stock corporations, like SQM, are subject to the partially integrated shareholder tax regime (sistema parcialmente integrado). The corporate tax rate applicable to us increased gradually from 20% to 25.5% in 2017. It will increase to a maximum rate of 27% in 2018.

The Tax Reform tax increase prompted a US$52.3 million increase in our deferred tax liabilities as of December 31, 2014. In accordance with IAS 12, the effects generated by the change in the income tax rate approved by Law No. 20.780 on income and deferred taxes were applied to the income statement. For purposes of the Company’s statutory consolidated financial statements filed with the CMF, in accordance with the instructions issued by the CMF in its circular 856 of October 17, 2014, the effects generated by the change in the income tax rate were accounted for as retained earnings. The amount charged to equity as of December 31, 2014 was US$52.3 million, thereby giving rise to a difference of US$52.3 million in profit for the year and income tax expense as presented in the Company’s Audited Consolidated Financial Statements compared with profit and income tax expense as presented in the Company’s statutory consolidated financial statements filed with the CMF.

The Chilean government may again decide to levy additional taxes on mining companies or other corporations in Chile, and such taxes could have a material adverse impact on our business, financial condition and results of operations.

| 50 |

We are also subject to the Chilean Labor Code and the Subcontracting Law, which are overseen by the Labor Authority (Dirección del Trabajo), the National Geology and Mining Service (Servicio Nacional de Geología y Minería or “Sernageomin”), and the National Health Service. Recent changes to these laws and their application may have a material adverse effect on our business, financial condition and results of operations. See “Item 3.D. Risk Factors—Risks Relating to Our Business—We are exposed to labor strikes and labor liabilities that could impact our production levels and costs.”

In addition, we are subject to Law No. 20,393, which establishes criminal liability for legal entities, for the crimes of (a) asset laundering, (b) financing terrorism and (c) bribery. Potential sanctions for violations under this law could include (i) fines, (ii) loss of certain governmental benefits during a given period, (iii) a temporary or permanent bar against the corporation executing contracts with governmental entities, and (iv) dissolution of corporation.

Finally, we are governed by the Securities Law and Law No. 18,046 on Corporations (Ley de Sociedades Anónimas or the “Chilean Corporations Act”), which regulates corporate governance. Specifically, the Chilean Corporations Act regulates, among other things, independent director requirements, disclosure obligations to the general public and to the CMF, as well as regulations relating to the use of inside information, the independence of external auditors, and procedures for the analysis of transactions with related parties. See “Item 6.C. Board Practices” and “Item 7.B. Related Party Transactions.”

There are currently no material legal or administrative proceedings pending against us except as discussed in Note 19.1 to our Consolidated Financial Statements and below under “Safety, Health and Environmental Regulations in Chile.”

Safety, Health and Environmental Regulations in Chile

Our operations in Chile are subject to both national and local regulations related to safety, health and environmental protection. In Chile, the main regulations on these matters that are applicable to us are the Mine Health and Safety Act of 1989 (Reglamento de Seguridad Minera or the “Mine Health and Safety Act”), the Health Code (Código Sanitario), the Health and Basic Conditions Act of 1999 (Reglamento sobre Condiciones Sanitarias y Ambientales Básicas en los Lugares de Trabajo or the “Health and Basic Conditions Act”), the Subcontracting Law and the Environmental Law of 1994, amended in 2010 (Ley sobre Bases Generales del Medio Ambiente or the “Environmental Law”).

Health and safety at work are fundamental aspects in the management of mining operations, which is why we have made constant efforts to maintain good health and safety conditions for the people working at our mining sites and facilities. In addition to the role played by us in this important matter, the Chilean government has a regulatory role, enacting and enforcing regulations in order to protect and ensure the health and safety of workers. The Chilean government, acting through the Ministry of Health and the Sernageomin, performs health and safety inspections at the mining sites and oversees mining projects, among other tasks, and it has exclusive powers to enforce standards related to environmental conditions and the health and safety of the people performing activities related to mining.

The Mine Health and Safety Act protects workers and nearby communities against health and safety hazards, and it provides for enforcement of the law where compliance has not been achieved. Our Internal Mining Standards (Reglamentos Internos Mineros) establish our obligation to maintain a workplace where safety and health risks are managed appropriately. We are subject to the general provisions of the Health and Basic Conditions Act, our own internal standards and the provisions of the Mine Health and Safety Act. In the event of non-compliance, the Ministry of Health and particularly the Sernageomin are entitled to use their enforcement powers to ensure compliance with the law.

| 51 |

In November 2011, the Ministry of Mining enacted Law No. 20,551 that Regulates the Closure of Mining Sites and Facilities (Ley que Regula el Cierre de Faenas e Instalaciones Mineras). This statute entered in force in November 2012 and required all mining sites to present or update their closure plans as of November 2014. SQM has fulfilled this requirement for all of its mining sites and facilities. The main requirements of the law are related to disclosures to the Sernageomin regarding decommissioning plans for each mining site and its facilities, along with the estimated cost to implement such plans. The mining site closure plans are approved by Sernageomin and the corresponding financial assurances are subject to approval by the CMF. In both cases, SQM has received the requisite approvals.

The new and modified Chilean Environmental Law defines the Ministry of the Environment as the governmental agency responsible for coordinating and supervising environmental issues. The Environmental Assessment Service is responsible for reviewing environmental assessments of new projects or significant modifications of existing ones, and the decision to grant or reject environmental permits rests with the Environmental Assessment Commission. On the other hand, the Superintendence for the Environment is responsible for supervising environmental performance during the construction, operation and closure of the projects that have been evaluated for environmental permits, and it is also responsible for enforcing compliance with prevention and atmospheric decontamination plans. The Environmental Law also promotes citizen participation in project evaluation and implementation, providing more opportunities for observations or objections to be made during the environmental evaluation process. Annually, the Superintendence for the Environment audits a sample of approved projects to verify compliance with the environmental permits, and it may pursue fines or sanctions if applicable, which can be challenged in the Environmental Court.

We continuously monitor the impact of our operations on the environment and on the health of our employees and other persons who may be affected by such operations. We have made modifications to our facilities in an effort to eliminate any adverse impacts. Also, over time, new environmental standards and regulations have been enacted, which have required minor adjustments or modifications of our operations. We anticipate that additional laws and regulations will be enacted over time with respect to environmental matters. There can be no assurance that future legislative or regulatory developments will not impose new restrictions on our operations. We are committed to continuously improving our environmental performance through our Environmental Management System (“EMS”), voluntary evaluations, such as Ecovadis, and international certifications, such as the Responsible Conduct certification from the Chilean Industrial Chemicals Association, which applies to our operations at Nueva Victoria, and the Protect&Sustain certification from the International Fertilizer Association, which applies to our operations at Coya Sur, the Salar de Atacama, Tocopilla, Antofagasta and Santiago.

We have submitted and will continue to submit several environmental impact assessment studies related to our projects to the governmental authorities. We require the authorization of these submissions in order to maintain and to increase our production capacity.

International Regulations

We are subject to complex regulatory requirements in the various jurisdictions in which we operate, including the following:

The European Parliament approved a new regulatory proposal for fertilizers, which will be discussed among the European Commission, the European Parliament and the Council of Member States of the European Union during 2018, before the final approval of the regulations. Following this, there will be a transition period for its implementation. The new European regulation proposes to reduce the maximum content limit of perchlorates in inorganic fertilizer with macronutrients, such as the potassium nitrate sold by us, to 0.005%. The fertilizers that we sell contain less than 0.005% of perchlorate. However, the Food Chain Security unit of the General Health and Consumer Affairs Council initiated the revision of the perchlorate limits in food that are currently in force and effect from July 2015, following the European Food Safety Authority’s (“EFSA”) evaluation of human exposure to perchlorate in food and in drinkable water. The definition of the new limits of perchlorates in food is being delayed and is expected to be established by the end of 2018.

| 52 |

With respect to the regulation on explosives in Europe, the revision process was initiated by the European Committee. We will continue to monitor the development of changes to the regulation through our participation in the Potassium Nitrate Association as part of the public-private committee created by the European Committee.

In January 2017, the modification of the Toxic Substances Control Act (“US-TSCA”) Chemical Substance Import Certification Process Revisions by the Department of Homeland Security of the United States became effective. This modification is related to the certification process of the compliance with US-TSCA for the chemical substances imported into the United States. According to the modification, SQM North America Corp. has to certify that each shipment of the chemical products imported to the United States, complies with the regulations. To achieve that, all export documents for the products from SQM´s headquarters to its subsidiaries in the United States were modified and the US-TSCA compliance declarations were requested from external providers.

In August 2017, United States Environmental Protection Agency (“US-EPA”) published a TSCA Inventory Notification (Active-Inactive) Requirements regulation under the US-TSCA which established that SQM North America Corp. must provide information with respect to all chemical substances imported to the United States during 2006-2016. We conducted a survey of all products imported to the United States from our headquarters, affiliates and other suppliers during this period to prepare the information per chemical substance to inform the US-EPA. This disclosure has to be made once but the information will be kept on record for 5 years.

On November 22, 2016, Normative Instruction No. 45 became effective in Brazil, which defines specification requirements, guarantees, product registration requirements, authorizations, packaging requirements, labeling of fertilizer products, and tolerance of mineral fertilizers, among others; and the changes defined for all exports from 2017. Normative Instruction No. 45 also defines changes to the information presented for the new registration of products and for the renewal of existing registries, and for the labels and certificates of already registered products, when applicable.

In May 2017, Resolution 0068 of the Ecuadorian Agribusiness Assurance Agency (AGROCALIDAD) became effective in Ecuador. The resolution establishes the general regulations for the registration and control of fertilizers. According to this regulation, SQM Ecuador S.A. must update all of its fertilizer records within 2 years from the date of issue of each certificate on the record.

4.D. Property, Plant and Equipment

We carry out our operations through the use of mining rights, production facilities and transportation and storage facilities. Discussion of our mining rights is organized below according to the geographic location of our mining operations. Our caliche ore mining interests are located throughout the valley of the Tarapacá and Antofagasta regions of northern Chile (in a part of the country known as “el Norte Grande”). From caliche ore, we produce products based on nitrates and iodine, and caliche also contains concentrations of potassium. Our mining interests in the brine deposits of the Salar de Atacama are found within the Atacama Desert, in the eastern region of el Norte Grande. From these brines we produce products based on potassium, sulfate, lithium and boron.

The map below shows the location of our principal mining operations and the exploitation and exploration mining concessions that have been granted to us, as well as the mining properties that we lease from Corfo:

Mining Concessions

Mining Concessions for the Exploration and Exploitation of Caliche Ore Mining Resources

We hold our mining rights pursuant to mining concessions for exploration and exploitation of mining resources that have been granted pursuant to applicable law in Chile:

| (1) | “Mining Exploitation Concessions”: entitle us to use the land in order to exploit the mineral resources contained therein on a perpetual basis, subject to annual payments to the Chilean government; and

| (2) | “Mining Exploration Concessions”: entitle us to use the land in order to explore for and verify the existence of mineral resources for a period of two years, at the expiration of which the concession may be extended one time only for two additional years, if the area covered by the concession is reduced by half. We may alternatively request an exploitation concession in respect of the area covered by the original exploration concession, which must be made within the timeframe established by the original exploration concession.

A Mining Exploration Concession is generally obtained for purposes of evaluating the mineral resources in a defined area. If the holder of the Mining Exploration Concession determines that the area does not contain commercially exploitable mineral resources, the Mining Exploration Concession is usually allowed to lapse. An application also can be made for a Mining Exploitation Concession without first having obtained a Mining Exploration Concession for the area involved.

As of December 31, 2017, the surface area covered by Mining Exploitation Concessions that have been granted in relation to the caliche resources of SQM S.A.’s mining sites is approximately 576,707 hectares. In addition, as of December 31, 2017, the surface area covered by Mining Exploration Concessions in relation to the caliche resources of SQM S.A.’s mining sites is approximately 2,200 hectares. We have not requested additional mining rights.

Mining Concessions for the Exploitation of Brines at the Salar de Atacama

As of December 31, 2017, our subsidiary SQM Salar held exclusive rights to exploit the mineral resources in an area covering approximately 140,000 hectares of land in the Salar de Atacama in northern Chile, of which SQM Salar is only entitled to exploit the mineral resources in 81,920 hectares. These rights are owned by Corfo and leased to SQM Salar pursuant to the Lease Agreement. Corfo cannot unilaterally amend the Lease Agreement, and the rights to exploit the resources cannot be transferred. The Lease Agreement establishes that SQM Salar is responsible for making quarterly lease payments to Corfo according to specified percentages of the value of production of minerals extracted from the Salar de Atacama brines, maintaining Corfo’s rights over the Mining Exploitation Concessions and making annual payments to the Chilean government for such concession rights. The Lease Agreement was entered into in 1993 and expires on December 31, 2030.

Under the terms of the Project Agreement, Corfo has agreed that it will not permit any other person to explore, exploit or mine any mineral resources in the approximately 140,000 hectares area of the Salar de Atacama mentioned above. The Project Agreement expires on December 31, 2030.

SQM Salar holds an additional 255,142 hectares of constituted Mining Exploitation Concessions in areas near the Salar de Atacama, which correspond to mining reserves that have not been exploited. SQM Salar also holds Mining Exploitation Concessions that are in the process of being granted covering 71,006 hectares in areas near the Salar de Atacama.

| 56 |

In addition, as of December 31, 2017, SQM Salar held Mining Exploration Concessions covering approximately 43,200 hectares and had applied for additional Mining Exploration Concessions of approximately 2,600 hectares. Exploration rights are valid for a period of two years, after which we can (i) request a Mining Exploitation Concession for the land, (ii) request an extension of the Mining Exploration Concession for an additional two years (the extension only applies to a reduced surface area equal to 50% of the initial area) or (iii) allow the concession to expire.

According to the terms of the Lease Agreement, with respect to lithium production, the CCHEN established a total accumulated extraction limit set at 180,100 tons of lithium (958,672 tons of lithium carbonate equivalent) in the aggregate for all periods while the Lease Agreement is in force. As of December 31, 2017, only 13 years remain on the term of the Lease Agreement and we had extracted approximately 64% of the total permitted accumulated extraction and sales limit of lithium.

On January 17, 2018, Corfo and our subsidiaries SQM Salar and SQM Potasio S.A. entered into the Corfo Arbitration Agreement which, among other things, provide for the amendments of the Lease Agreement and the Project Agreement. As part of the agreement to amend the Lease Agreement, Corfo authorized an increase of the production and sales of lithium products produced in the Salar de Atacama up to 349,553 metric tons of lithium metallic equivalent (1,860,670 tons of lithium carbonate equivalent), which is in addition to the approximately 64,816 metric tons of lithium metallic equivalent (345,015 tons of lithium carbonate equivalent) remaining from the originally authorized amount. See “Item 3.D. Risk Factors” and “Item 8.A.7 Legal Proceedings.”

Concessions Generally

As of December 31, 2017, approximately 97% of SQM’s mining interests were held pursuant to Mining Exploitation Concessions and 3% pursuant to Mining Exploration Concessions. Of the Mining Exploitation Concessions, approximately 94% already have been granted pursuant to applicable Chilean law, and approximately 6% are in the process of being granted. Of the Mining Exploration Concessions, approximately 90% already have been granted pursuant to applicable Chilean law, and approximately 10% are in the process of being granted.

In 2017, we made payments of approximately US$7.7 million to the Chilean government for Mining Exploration and Exploitation Concessions, including the concessions we lease from Corfo. These payments do not include the payments we made directly to Corfo pursuant to the Lease Agreement, according to the percentages of the sales price of products produced using brines from the Salar de Atacama.

The following table shows the Mining Exploitation and Exploration Concessions held by SQM, including the mining properties we lease from Corfo, as of December 31, 2017:

|  | Exploitation Concessions |  |  | Exploration Concessions |  |  | Total |
Region of Chile |  | Total Number |  |  | Hectares |  |  | Total Number |  |  | Hectares |  |  | Total Number |  |  | Hectares |
Region I |  |  | 2,815 |  |  |  | 529,497 |  |  |  | 46 |  |  |  | 21,700 |  |  |  | 2,861 |  |  |  | 551,197 |
Region II |  |  | 9,052 |  |  |  | 2,382,906 |  |  |  | 213 |  |  |  | 68,500 |  |  |  | 9,265 |  |  |  | 2,451,406 |
Region III and others |  |  | 423 |  |  |  | 98,749 |  |  |  | 36 |  |  |  | 9,900 |  |  |  | 459 |  |  |  | 108,649 |
Total |  |  | 12,290 |  |  |  | 3,011,152 |  |  |  | 295 |  |  |  | 100,100 |  |  |  | 12,585 |  |  |  | 3,111,252 |

The majority of the Mining Exploitation Concessions held by SQM were requested primarily for non-metallic mining purposes. However, a small percentage of our Mining Concessions were requested for metallic mining purposes. The annual payment to the Chilean government for this group of concessions is higher.

| 57 |

Geological studies over mining properties that were requested primarily for non-metallic mining purposes may show that the concession area is of interest for metallic mining purposes, in which case we must inform the Sernageomin, indicating that the type of substance contained by such Mining Concessions has changed, for purposes of the annual payment for these rights.

Caliche: Facilities and Reserves

Caliche: Facilities

During 2017, caliche ore mining operations were focused in the first region of Chile, and our Nueva Victoria mine was exploited. In November 2015, the mining and nitrate operations at Pedro de Valdivia were suspended, and iodine production was reduced at the Pedro de Valdivia site, in order to take advantage of the highly efficient production facilities at Nueva Victoria. Operations at the Pampa Blanca site were suspended in 2010, and operations at the María Elena site were suspended in October 2013.

Nueva Victoria

The Nueva Victoria mine and facilities are located 140 kilometers southeast of Iquique and are accessible by highway. Since 2007, the Nueva Victoria mine includes the mining properties Soronal, Mapocho and Iris. At this site, we use caliche to produce salts rich in nitrates and iodine, through heap leaching and the use of solar evaporation ponds. The main production facilities at this site include the operation centers for the heap leaching process, the iodide and iodine plants at Nueva Victoria and Iris and the evaporation ponds at the Sur Viejo sector of the site. The areas currently being mined are located approximately 4 kilometers northeast of Nueva Victoria. Solar energy and electricity are the primary sources of power for this operation. We are currently developing a project to expand the production capacity of iodide and iodine in Nueva Victoria to reach 11,000 metric tons per year.

Pampa Blanca

The mining facilities at Pampa Blanca, which is located 100 kilometers northeast of Antofagasta, have been suspended since March 2010. At this site, we used caliche to produce nitrates and iodine through heap leaching and the use of solar evaporation ponds. The main production facilities at this site included the operation centers for the heap leaching system and the iodide plant. Electricity was the primary source of power for this operation.

Pedro de Valdivia

The Pedro de Valdivia mine and facilities are located 170 kilometers northeast of Antofagasta and are accessible by highway. At this site, we used caliche to produce nitrates and iodine through vat leaching and solar evaporation ponds. The main production facilities at this site include the crushing, vat leaching, fines processing, nitrate crystallization plant, and iodide and iodine plants. In November 2015, the mining and nitrate operations at Pedro de Valdivia were suspended, and iodine production was reduced. Electricity, natural gas and fuel oil are the primary sources of power for this operation.

María Elena

The María Elena mine and facilities, named El Toco, are located 220 kilometers northeast of Antofagasta and are accessible by highway. Until February 2010, caliche was used at this facility to produce nitrates and iodine through vat leaching. Subsequently, these facilities were equipped to produce nitrates and iodine through the use of heap leaching and solar evaporation ponds. Heap leaching operations at this site were suspended in October 2013. During 2017, we continued to produce solutions rich in iodine and nitrates by leaching the mine tailings. These solutions are treated at the iodide plant at María Elena, and subsequently the prilled iodine is produced at Pedro de Valdivia.

| 58 |

Caliche: Reserves

Our in-house staff of geologists and mining engineers prepares our estimates of caliche ore reserves. The Proven and Probable Reserve figures presented below are estimates, and may be subject to modifications due to natural factors that affect the distribution of mineral grades, which would, in turn, modify the recovery of nitrate and iodine. Therefore, no assurance can be given that the indicated levels of recovery of nitrates and iodine will be realized.

We estimate ore reserves based on evaluations, performed by engineers and geologists, of assay values derived from sampling of drill-holes and other openings. Drill-holes have been made at different space intervals in order to recognize mining resources. Normally, we start with 400x400 meters and then we reduce spacing to 200x200 meters, 100x100 meters and 50x50 meters. The geological occurrence of caliche ore is unique and different from other metallic and non-metallic minerals. Caliche ore is found in large horizontal layers at depths ranging from one to four meters and has an overburden between zero and two meters. This horizontal layering is a natural geological condition and allows the Company to estimate the continuity of the caliche bed based on surface geological reconnaissance and analysis of samples and trenches. Mineral resources can be calculated using the information from the drill-hole sampling.

A Mineral Resource is a concentration or occurrence of natural, solid, inorganic or fossilized organic material in or on the Earth’s crust in such form or quantity and of such grade or quality that it has reasonable prospects for economic extraction. The location, quantity, grade, geological characteristics and continuity of a mineral resource are known, estimated or interpreted from specific geological, metallurgical and technological evidence.

A Measured Resource is the part of a Mineral Resource for which tonnage, densities, shape, physical characteristics, grade and mineral content can be estimated with a high level of confidence. The estimate is based on detailed exploration, sampling and testing information gathered through appropriate sampling techniques from locations such as outcrops, trenches, and exploratory drill holes.

An Indicated Mineral Resource is the part of a Mineral Resource for which tonnage, densities, shape, physical characteristics, grade and mineral content can be estimated with a reasonable level of confidence. The estimate is based on detailed exploration, sampling and testing information gathered through appropriate sampling techniques from locations such as outcrops, trenches and exploratory drill holes.

According to our experience in caliche ore, the grid pattern drill-holes with spacing equal to or less than 100 meters produce data on the caliche resources that is sufficiently defined to consider them Measured Resources and then, adjusting for technical, economic and legal aspects, as Proven Reserves. These reserves are obtained using the Kriging Method and the application of operating parameters to obtain economically profitable reserves.

Similarly, the information obtained from detailed geologic work and samples taken from grid pattern drill-holes with spacing equal to or less than 200 meters can be used to determine Indicated Resources. By adjusting such Indicated Resources to account for technical, economic and legal factors, it is possible to calculate Probable Reserves. Probable Reserves are calculated by using a polygon-based methodology and have an uncertainty or margin of error greater than that of Proven Reserves. However, the degree of certainty of Probable Reserves is high enough to assume continuity between points of observation.

Proven Reserves are the economically mineable part of a Measured Resource. The calculation of the reserves includes the application of mining parameters including maximum overburden, minimum thickness of caliche ore, stripping ratio, cutoff grade and application of dilution factors to the grade values. Appropriate assessments, including pre-feasibility studies or feasibility studies, have been carried out and include consideration of metallurgical, economic, marketing, legal, environmental, social and governmental factors. These assessments demonstrate at the time of reporting that extraction is reasonably justified.

Probable Reserves are the economically mineable part of an Indicated Resource and in some cases a Measured Resource. The calculation of the reserves includes the application of mining parameters including maximum overburden, minimum thickness of caliche ore, stripping ratio, cutoff grade and application of dilution factors to the grade values. Appropriate assessments, including pre-feasibility studies, have been carried out or are in process and include consideration of metallurgical, economic, marketing, legal, environmental, social and governmental factors. These assessments demonstrate at the time of reporting that extraction is reasonably justified.

The estimates of Proven Reserves of caliche ore at each of our mines as of December 31, 2017 are set forth below. The Company holds 100% of the concession rights for each of these mines.

Mine |  | Proven Reserves (1) (millions of metric tons) |  |  | Nitrate Average Grade (percentage by weight) |  |  | Iodine Average Grade (parts per million) |  |  | Cutoff Grade Average for Mine (2)
Pedro de Valdivia |  |  | 109.0 |  |  |  | 7.1 | % |  |  | 377 |  |  | Nitrate 6.0 %
María Elena |  |  | 83.3 |  |  |  | 7.2 | % |  |  | 436 |  |  | Iodine 300 ppm
Pampa Blanca |  |  | 54.7 |  |  |  | 5.7 | % |  |  | 538 |  |  | Iodine 300 ppm
Nueva Victoria |  |  | 346.2 |  |  |  | 6.3 | % |  |  | 426 |  |  | Iodine 300 ppm

In addition, the estimates of our Probable Reserves of caliche ore at each of our principal mines as of December 31, 2017, are as follows:

Mine |  | Probable Reserves (3) (millions of metric tons) |  |  | Nitrate Average Grade (percentage by weight) |  |  | Iodine Average Grade (parts per million) |  |  | Cutoff Grade (2)
Pedro de Valdivia |  |  | 334.7 |  |  |  | 7.3 | % |  |  | 421 |  |  | Nitrate 6.0 %
María Elena |  |  | 148.8 |  |  |  | 7.2 | % |  |  | 381 |  |  | Iodine 300 ppm
Pampa Blanca |  |  | 464.6 |  |  |  | 5.7 | % |  |  | 540 |  |  | Iodine 300 ppm

| (1) | The Proven Reserves set forth in the table above are shown before losses related to exploitation and mineral treatment. Proven Reserves are affected by mining exploitation methods, which result in differences between the estimated reserves that are available for exploitation in the mining plan and the recoverable material that is finally transferred to the leaching vats or heaps. The average mining exploitation factor for each of our different mines ranges between 80% and 90%, whereas the average global metallurgical recoveries of processes for nitrate and iodine contained in the recovered material vary between 60% and 70%.

| (2) | The cutoff grades for the Proven and Probable Reserves vary according to the objectives of each mine. These amounts correspond to the averages of the different areas.

| (3) | Probable Reserves can be expressed as Proven Reserves using a conversion factor, only for purposes of obtaining a projection to be used for long-term planning purposes. On average, this conversion factor is higher than 60%, depending on geological conditions and caliche ore continuity, which vary from mine to mine (Pedro de Valdivia 60%, María Elena 50%, Pampa Blanca 70% and Nueva Victoria 60%).

The complete technical supporting documentation for the information set forth in the table above is contained in the report “Methodology, Procedure, and Classification of SQM’s Nitrate and Iodine Resources and Reserves for the Year 2017,” was prepared for each mine by the geologist Vladimir Tejerina and other engineering professionals employed by SQM and validated by Mr. Sergio Alarcón and Mr. Orlando Rojas.

The proven and probable reserves shown above are the result of the evaluation of approximately 20.98% of the total caliche-related mining property of our Company. However, we have explored more intensely the areas in which we believe there is a higher potential of finding high-grade caliche ore minerals. The remaining 79.02% of this area has not been explored or has had limited reconnaissance, which is not sufficient to determine the sources of potential and hypothetical resources. In 2017, we did not carry out basic reconnaissance of new mining properties. With respect to detailed explorations, in 2017, we carried out recategorizations of indicated resources in the Nueva Victoria West South and Tente en el Aire sectors, totaling 1,493.9 hectares, which is still in process. Our 2018 exploration program includes the exploration of the Tente en el Air section, which totals 3,114 hectares, and the basic study of 24,607 hectares of Franja Oeste sector. The reserves shown in these tables are calculated based on properties that are not involved in any legal disputes between SQM and other parties.

Caliche ore is the key raw material used in the production of iodine, specialty plant nutrients and industrial chemicals. The following gross margins for the business lines specified were calculated on the same basis as cut off grades used to estimate our reserves. We expect costs to remain relatively stable in the near future.

|  | 2017 |  | 2016 |  | 2015
|  | Gross Margin |  |  | Price |  | Gross Margin |  |  | Price |  | Gross Margin |  |  | Price
Iodine and Derivatives |  |  | 21 | % |  | US$20/kg |  |  | 17 | % |  | US$23/kg |  |  | 30 | % |  | US$28/kg
Specialty Plant Nutrition |  |  | 20 | % |  | US$722/ton |  |  | 23 | % |  | US$742/ton |  |  | 29 | % |  | US$784/ton
Industrial Chemicals |  |  | 32 | % |  | US$809/ton |  |  | 35 | % |  | US$808/ton |  |  | 27 | % |  | US$770/ton

We maintain an ongoing program of exploration and resource evaluation on the land surrounding our production mines, and other sites for which we have the appropriate concessions.

Brines from the Salar de Atacama: Facilities and Reserves

Salar de Atacama: Facilities

Salar de Atacama

Our facilities at the Salar de Atacama are located 208 kilometers to the east of the city of Antofagasta and 188 kilometers to the southeast of the city of María Elena. At this site we use brines extracted from the salar to produce potassium chloride, potassium sulfate, boric acid, magnesium chloride salts and lithium solutions, which are subsequently sent to our lithium carbonate plant at the Salar del Carmen for processing. The main production plants at this site include the potassium chloride flotation plants (MOP-H I and II), the potassium carnallite plants (PC I and extension), the potassium sulfate flotation plant (SOP-H), the boric acid plant (ABO), the potassium chloride drying plant (Dual Plant or MOP-S), the potassium chloride compacting plant (MOP-G), the potassium sulfate drying plant (SOP-S) and the potassium sulfate compacting plant (SOP-G). Solar energy is the primary energy source used for the Salar de Atacama operations.

Salar de Atacama: Reserves

Our in-house staff of hydro-geologists and geologists prepares our estimates of the reserve base of potassium, sulfate, lithium and boron dissolved in brines at the Salar de Atacama. We have exploitation concessions covering an area of 81,920 hectares, in which we have carried out geological exploitation, brine sampling and geostatistical analysis. We estimate that our proven and probable reserves as of December 31, 2017, based on economic restrictions, geological exploitation, brine sampling and geostatistical analysis up to a depth of 110 meters of our total exploitation concessions, and additionally, up to a depth of 300 meters over approximately 47% of the same total area, are as follows:

|  | Proven Reserves (1) (millions of metric tons) |  |  | Probable Reserves (1) (millions of metric tons) |  |  | Total Reserves (millions of metric tons) |
Potassium (K+) (2) |  |  | 52.00 |  |  |  | 38.47 |  |  |  | 90.47 |
Sulfate (SO4-2) (3) |  |  | 42.71 |  |  |  | 39.65 |  |  |  | 82.35 |
Lithium (Li+) (4) |  |  | 4.80 |  |  |  | 3.33 |  |  |  | 8.13 |
Boron (B3+) (5) |  |  | 1.56 |  |  |  | 1.27 |  |  |  | 2.83 |

| (1) | Metric tons of potassium, sulfate, lithium and boron considered in the proven and probable reserves are shown before losses from evaporation processes and metallurgical treatment. The recoveries of each ion depend on both brine composition and the process applied to produce the desired commercial products.

| (2) | Recoveries for potassium vary from 47% to 77%.

| (3) | Recoveries for sulfate vary from 27% to 45%.

| (4) | Recoveries for lithium vary from 28% to 40%.

| (5) | Recoveries for boron vary from 28% to 32%.

The information set forth in the table above was validated in February 2018 by Messrs. Álvaro Henríquez and Orlando Rojas using information that was prepared by SQM’s hydrogeologists, geologists and engineers and external advisors.

Mr. Henríquez is a geologist with more than 14 years of experience in the field of mining hydrogeology. He is currently employed by SQM as Superintendent of Hydrogeology, in the Salar Hydrogeology department. He is a Competent Person and is registered under No. 226 in the Public Registry of Competent Persons in Mining Resources and Reserves, in accordance with the Competent Person Law. As a hydrogeologist in Chile and abroad, he has evaluated multiple brine-based projects and has experience evaluating resources and reserves.

Mr. Orlando Rojas is a civil mining engineer and independent consultant. He is Partner and Chief Executive Officer of the company EMI-Ingenieros y Consultores S.A., whose offices are located at Renato Sánchez No. 3357, Las Condes, Santiago, Chile. He is a member of the Institute of Mining Engineers and is registered under No. 118 in the Public Registry of Competent Persons in Mining Resources and Reserves in accordance with the Competent Person Law and related regulations. He has worked as a mining engineer for 40 years since graduating from university, including more than 34 years working on estimates for reserves and resources.

| 62 |

Copies of the certificate of qualified competency issued by the Chilean Mining Commission for Mr. Rojas and Mr. Henríquez are attached hereto as Exhibit 99.2 and 99.3.

A cutoff grade of 1.0% K is used in the calculation, considering a low margin scenario using only MOP-S as and using diluted brine with higher levels of contaminants as the raw material and with recovery yields of approximately 47%, which is on the lower end of the range. In this scenario, considering current market conditions and market conditions from recent years, the production cost of MOP production is still competitive.

The cutoff grade for lithium extraction is set at 0.05% Li. The cost of the process is competitive in the market despite a small cost increase due to the expansions in the evaporation area (to reach the required Li concentration) and to the use of additives to maintain the quality of the brine that is used to feed the plant.

The proven and probable reserves are based on production experience, drilling, brine sampling and geo-statistic reservoir modeling in order to estimate brine volumes and their composition. We calculate the reserve base, which is the volume of brine effectively drainable or exploitable in each evaluation unit, by building a three-dimensional block model. The following variables are used to populate the model:

| · | Porosity: obtained from measurements of drainable porosity in core rocks, test pumping data, geophysical records and changes in the level of the brine. The volume of brine is estimated on the basis of the interpolation of the drainable porosity data.

| · | Grades: The brine chemistry is subjected to an exploratory data analysis and a variographic analysis, in order to determine the chemical populations in the Salar. Subsequently, the grades are interpolated using the Kriging method.

Based on the chemical characteristics, the volume of brine and drainable porosity, we determine the number of metric tons for each of the chemical ions being evaluated.

Reserves are defined as hydrogeological units with proven historical brine yield production, and a quality and piezometric brine monitoring network to control brine evolution over time. Reserve classification is finally achieved by using the geostatistical estimation error and hydrogeological knowledge of the units that have been explored, as an indicator between proven and probable reserves.

Probable reserves and inferred resources are being explored in order to be able to reclassify them as proven reserves and indicated or measured resources, respectively. This exploration includes systematic packer testing, chemical brine sampling and long-term pilot production pumping tests.

We consider chemical parameters to determine the process to be applied to the brines. These parameters are used to estimate potential restrictions on production yields, and the economic feasibility of producing such commercial products as potassium chloride, potassium sulfate, lithium carbonate and boric acid is determined on the basis of the evaluation.

Complementing the reserves information, SQM has an environmental impact assessment (RCA 226/06) which defines a maximum brine extraction until the end of the Lease Agreement (December 31, 2030). Considering the authorized maximum brine production rates, and including reinjection factors, we have performed several hydrogeological numeric simulations to estimate changes in the volume and quality of the brine during the life of the project, considering the same ponds infrastructure existing on January 1, 2018. According to these simulations, a total of 20.9 million metric tons of potassium and 1.55 million metric tons of lithium will be extracted from the producing wells, without considering the returns by direct and indirect reinjection. On the other hand, the proven and probable base reserve, within the authorized area of environmental extraction (RCA 226/06), corresponds to 34.01 million metric tons of potassium and 3.99 million metric tons of lithium, enough to satisfy the demand of the project until the end of the concession.

| 63 |

Brines from the Salar de Atacama are the key raw material used in the production of potassium chloride and potassium sulfate, and lithium and its derivatives. The following gross margins for the business lines specified were calculated on the same basis as cut off grades used to estimate our reserves. We expect costs to remain relatively stable in the near future.

|  | 2017 |  | 2016 |  | 2015
|  | Gross Margin |  |  | Price |  | Gross Margin |  |  | Price |  | Gross Margin |  |  | Price
Potassium Chloride and Potassium Sulfate |  |  | 17 | % |  | US$282/ton |  |  | 11 | % |  | US$263/ton |  |  | 29 | % |  | US$347/ton
Lithium and Derivatives |  |  | 71 | % |  | US$12,970/ton |  |  | 66 | % |  | US$10,362/ton |  |  | 51 | % |  | US$5,759/ton

Other Production Facilities

Coya Sur

The Coya Sur site is located approximately 15 kilometers south of María Elena, and production activities undertaken there are associated with the production of potassium nitrate and finished products. The main production plants at this site include four potassium nitrate plants with a total capacity of 1,300,000 metric tons per year. There are also five production lines for crystallized nitrates, with a total capacity of 1,200,000 metric tons per year, and a prilling plant with a capacity of 320,000 metric tons per year. The potassium nitrate produced at Coya Sur is an intermediate product that is used as a raw material for the production of finished products (crystallized nitrates and prilled nitrates). Therefore, the production capacities listed above are not independent of one another and cannot be added together to obtain an overall total capacity. Natural gas is the main source of energy for our Coya Sur operation.

Salar del Carmen

The Salar del Carmen site is located approximately 14 kilometers to the east of Antofagasta. The production plants at this facility include the lithium carbonate plant, with a production capacity of 48,000 metric tons per year, and the lithium hydroxide plant, with a production capacity of 6,000 metric tons per year. Electricity and natural gas are the main sources of energy for our Salar del Carmen operation.

| (1) | Approximate size considers both the production facilities and the mine for María Elena, Nueva Victoria, Pampa Blanca, Pedro de Valdivia and the Salar de Atacama. Mining areas are those authorized for exploitation by the environmental authority and/or Sernageomin.

| (2) | Weighted average age and gross book value correspond to production facilities, excluding the mine, for María Elena, Nueva Victoria, Pampa Blanca, Pedro de Valdivia and the Salar de Atacama.

| (3) | Includes production facilities and solar evaporation ponds.

| (4) | The potassium nitrate produced at Coya Sur is an intermediate product that is used as a raw material for the production of finished products (crystallized nitrates and prilled nitrates). Therefore, the production capacities listed above are not independent of one another and cannot be added together to obtain an overall total capacity.

| (5) | Includes production facilities, solar evaporation ponds and leaching heaps.

| (6) | Operations at the El Toco mine at María Elena were suspended in November 2013.

| (7) | The nominal production capacity for iodine considers the capacity of our plants. The effective capacity is 11,000 metric tons per year.

| (8) | Operations at Pampa Blanca were suspended in March 2010.

| (9) | In November 2015, the mining and nitrate operations at Pedro de Valdivia were suspended, and iodine production was reduced at the Pedro de Valdivia site, in order to take advantage of the highly efficient production facilities at Nueva Victoria.

| (10) | Potassium chloride and potassium sulfate are produced in a dual plant, and the production capacity for each of these products depends on the production mix. Therefore, the production capacities for these two products are not independent of one another and cannot be added together to obtain an overall total capacity.

| (11) | The Tocopilla port facilities were originally constructed in 1961 and have been refurbished and expanded since that time.

The railway line that runs between our Coya Sur production facilities and our Tocopilla port facilities was damaged in August 2015 as a result of storms in the north of Chile. The train is not currently operating and as a consequence, we have replaced the train with trucks to ship products from Coya Sur. Detailed engineering studies were performed to assess the damage of the railway. During the third quarter of 2016, the report was completed; it concluded that the cost and time needed to repair the railway at this time is not economical in the short and medium term. As a result of this determination, the Company wrote-off the assets related to the train. We do not believe it will materially impact future sales volumes or transportation costs.

| 65 |

We consider the condition of our principal plant and equipment to be good, with the exception of the railway line.

We directly or indirectly through subsidiaries own, lease or hold concessions over the facilities at which we carry out our operations. Such facilities are free of any material liens, pledges or encumbrances, and we believe they are suitable and adequate for the business we conduct in them.

| (1) | In November 2015, mining and nitrate operations at Pedro de Valdivia were suspended, and iodine production was reduced at the Pedro de Valdivia site, in order to take advantage of the highly efficient production facilities at Nueva Victoria.

| (2) | Operations at the Pampa Blanca mine were suspended in March 2010. During 2015, María Elena obtained production from caliche ore exploited in prior years.

| (3) | Includes production at Coya Sur from treatment of nitrates solutions from María Elena and Pedro de Valdivia, nitrate salts from pile treatment at Nueva Victoria, and net production from NPT, or technical grade potassium nitrate, plants.

| (4) | Lithium carbonate is extracted at the Salar de Atacama and processed at our facilities at the Salar del Carmen. Potassium salts include synthetic sylvinite produced in the plant and other harvested potassium salts (natural sylvinite, carnalites and harvests from plant ponds) that are sent to Coya Sur for the production of crystallized nitrates.

Transportation and Storage Facilities

The transportation of our products is carried out by trucks that are operated by dedicated third parties through long term contracts. Furthermore, we own port and storage facilities for the transportation and management of finished products and consumable materials.

Our main centers for the production and storage of raw materials are the Nueva Victoria, Coya Sur and Salar de Atacama facilities. Other facilities include chemical plants for the finished products of lithium carbonate and lithium hydroxide at the Salar del Carmen plant. The Port of Tocopilla terminal, which we own, has a surface area of approximately 22 hectares and is the principal facility for the storage and shipment of our bulk products and packaged potassium chloride (MOP), potassium sulfate (SOP) and nitrates.

The nitrate finished products are produced at our Coya Sur facilities and then transported via trucks to the Port of Tocopilla terminal where they are stored and shipped, either packaged (polypropylene bags, polyethylene or polypropylene FIBC big bags) or in bulk. The potassium chloride is produced at our Salar de Atacama facilities and we transport it by truck, either to the Port of Tocopilla terminal or the Coya Sur facility. The product transported to Coya Sur is an intermediate product that is used as a raw material for the production of potassium nitrate. On the other hand, the product transported to the Port of Tocopilla is a final product that will be shipped or transported to the client or affiliate. The raw material of nitrate for the production of potassium nitrate in Coya Sur is currently produced at Nueva Victoria and the remaining raw material is provided from historical stock stored in Coya Sur that was produced at the Pedro de Valdivia facility when it was operating. This raw material is obtained from the processing of caliche that is extracted from our mines. On the other hand, potassium sulfate is produced at our Salar de Atacama facilities and later transported by trucks to the Port of Tocopilla terminal.

The lithium chloride solution, which contains a high concentration of boron, produced at our Salar de Atacama facilities, is transported to the lithium carbon plant in the Salar del Carmen area where the finished lithium carbonate is produced. Part of the lithium carbonate is provided to the adjacent lithium hydroxide plant where the finished lithium hydroxide is produced. These two products are packed in packaging of distinct characteristics (polyethylene bags, multi-layer or polypropylene FIBC big bags), stored within the same facilities and secured in roofed storerooms. Thereafter, they are consolidated into containers that are transported by trucks to a transit warehouse or directly to port terminals for their subsequent shipment. The port terminals used are currently suited to receive container ships and are situated in Antofagasta, Mejillones and Iquique.

Iodine obtained from the same caliche used for the production of nitrates, is processed, packaged and stored exclusively in the Pedro de Valdivia and Nueva Victoria facilities. The packaging used for iodine are drums and polypropylene FIBC big bags with an internal polyethylene bag and oxygen barrier, which at the time of transportation are consolidated into containers and sent by truck to port terminals suited for their management, principally located in Antofagasta, Mejillones and Iquique. Thereafter, they are sent to distinct markets by container ship or by truck to Santiago where iodine derivatives are produced in the Ajay-SQM Chile plants.

| 67 |

The Port of Tocopilla terminal facilities are located approximately 186 kilometers north of Antofagasta, approximately 124 kilometers west of María Elena and Coya Sur and 372 kilometers to the west of Salar de Atacama. Our affiliate, Servicios Integrales de Tránsitos y Transferencias S.A. (SIT), operates facilities for the shipment of products and the delivery of certain raw materials based on renewable concessions granted by Chilean regulatory authorities, provided that the facilities are used in accordance with the authorization granted and we pay an annual concession fee. The Port of Tocopilla terminal facilities include a truck weighing machine that confirms product entry into the port and transfers the product to distinct storage zones, a piezometer within the shipping system to carry out bulk product loaded onto ships and a crane with a 40 ton capacity for the loading of sealed product onto ships.

The storage facilities consist of a system of six silos, with a total storage capacity of 55,000 metric tons, and a mixed storage area of open storehouses with a total storage capacity of approximately 250,000 metric tons. In addition, to fulfill future storage needs, we will continue to make investments in accordance with the investment plan outlined by management. The products are also put into bags at the Port of Tocopilla terminal facilities where the bagging capacity is established by two bag packaging machines, one for sacks and polypropylene FIBC big bags and one for FFS polyethylene. The products that are packaged in Tocopilla may be subsequently shipped at the same port or may also be consolidated into trucks or containers for its subsequent dispatch to clients by land or sea through containers from other ports, principally located in Antofagasta, Mejillones and Iquique.

For the transportation of bulk product, the transportation belt system extends across the coastline to deliver products directly to the hatches of bulk cargo ships. The nominal load capacity of this shipping system is 1,200 tons per hour. The transportation of packaged product is carried out utilizing the same bulk cargo ships using trailers without motors located in the dock and loaded by a crane with a 40 ton capacity from the Port of Tocopilla terminal. Thereafter, they are towed and unloaded using ship cranes to the respective warehouses.

We normally contract bulk cargo ships to transfer the product from the Port of Tocopilla terminal to our hubs around the world or to clients directly, who, in certain instances, use their own contracted vessels for delivery.

Tocopilla processes related to the reception, handling, storage and shipment of bulk/packaged nitrates produced at Coya Sur are certified by the third-party organization TÜV-Rheiland under the quality standard ISO 9001:2008.

Computer System

In addition to the above-listed facilities, we operate varies computer and information systems linking our principal subsidiaries to our operating facilities throughout Chile via a local area network. The computer and information system is used mainly for accounting, monitoring of supplies and inventories, billing, quality control, research activities and production process and maintenance control. The mainframe computing system is located at our offices in Santiago.

In addition, we have incorporated Cloud technologies to have a platform that allows us to support new business processes, related to IoT (Internet of Things), Advanced Analytics and business enablers.

| ITEM 5. | OPERATING AND FINANCIAL REVIEW AND PROSPECTS

The information in this Item 5 should be read in conjunction with the Company’s Consolidated Financial Statements and the notes thereto included elsewhere in this Annual Report.

Since January 1, 2010, the Company’s Consolidated Financial Statements have been prepared in accordance with the International Financial Reporting Standards as published by the International Accounting Standards Board (IASB).

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

Critical accounting policies are defined as those that are reflective of significant judgments and uncertainties, which would potentially result in materially different results under different assumptions and conditions.

We believe that our critical accounting policies applied in the preparation of our Audited Consolidated Financial Statements are limited to those described below. It should be noted that in many cases, IFRS specifically dictates the accounting treatment of a particular transaction, limiting management’s judgment in their application. There are also areas in which management’s judgment in selecting available alternatives would not produce materially different results.

Trade and Other Accounts Receivable

Trade and other accounts receivable relate to non-derivative financial assets with fixed payments that can be determined and are not quoted in any active market. These arise from sales operations involving products and/or services that we sell directly to our customers that are not within the following categories:

• those which we have the intention of selling immediately in the near future and which are held-for-sale;

• those designated at their initial recognition as available-for-sale; and

• those through which we do not intend to recover for reasons other than credit impairment and therefore must be classified as available-for-sale.

These assets are initially recognized at their fair value (which is equivalent to their face value, discounting implicit interest for installment sales) and subsequently at amortized cost according to the effective interest rate method less a provision for impairment loss. When the face value of the account receivable does not significantly differ from its fair value, it is recognized at face value. An allowance for impairment loss is established for trade accounts receivable when there is objective evidence that we will not be able to collect all the amounts owed to us according to the original terms of accounts receivable. The Company calculates the allowance for doubtful accounts corresponding to receivables that are not guaranteed or insured as a function of the delays that may occur in the collection of such accounts.

Implicit interest in installment sales is recognized as interest income when interest is accrued over the term of the sale.

Income tax

Corporate income tax for the year is determined as the sum of current taxes from the different consolidated companies.

| 69 |

Current taxes are based on the application of the various types of taxes attributable to taxable income for the year.

Differences between the book value of assets and liabilities and their tax basis generate the balance of deferred tax assets or liabilities, which are calculated using the tax rates expected to be applicable when the assets and liabilities are realized.

In conformity with current Chilean tax regulations, the provision for corporate income tax and taxes on mining activity is recognized on an accrual basis, presenting the net balances of accumulated monthly tax provisional payments for the fiscal period and associated credits. The balances of these accounts are presented in current income taxes recoverable or current taxes payable, as applicable.

Tax on companies and variations in deferred tax assets or liabilities that are not the result of business combinations are recorded in the statement of income accounts or equity accounts in the consolidated statement of financial position, considering the origin of the gains or losses which have generated them.

At each reporting period, the carrying amount of deferred tax assets was reviewed and reduced to the extent where there would not be sufficient taxable income to allow the recovery of all or a portion of the deferred tax assets. Likewise, as of the date of the consolidated financial statements, deferred tax assets are evaluated and recognized if it is more likely than not that future taxable income will allow for recovery of the deferred tax asset.

With respect to deductible temporary differences associated with investments in subsidiaries, associated companies and interest in joint ventures, deferred tax assets are recognized solely provided that it is more likely than not that the temporary differences will be reversed in the near future and that there will be taxable income with which they may be used.

The deferred income tax related to entries directly recognized in equity is recognized with an effect on equity and not with an effect on profit or loss.

Deferred tax assets and liabilities are offset if there is a legally receivable right of offsetting tax assets against tax liabilities and the deferred tax is related to the same tax entity and authority.

Inventories

The Company measures inventories at the lower of production cost and net realizable value. The cost price of finished products and work in progress includes the direct cost of materials and, when applicable, labor costs, the depreciation of goods that are involved in the production process, the indirect costs incurred in transforming raw materials into finished products, and general expenses incurred in carrying inventories to their current location and conditions. The method used to determine the cost of inventories is the weighted average monthly cost and the average cost of warehouse storage.

Commercial discounts, rebates obtained, and other similar entries are deducted when determining the acquisition price.

The net realizable value represents the estimate of the sales price, less all the estimated costs involved in making the finished product and the costs that will be incurred in the commercialization, sales, and distribution processes.

The Company conducts an evaluation of the net realizable value of inventories at the end of each year, recording an estimate with a charge to profit or loss when the inventory costs exceed the realizable value. This estimate is made for all the finished and intermediate products in the Company’s inventory. The valuation of obsolete, impaired or slow-moving products relates to their estimated net realizable value.

| 70 |

The provisions for uncertainties in the technical specifications for the Company’s stocks of finished goods and work in progress have been made based on a technical study which covers the different variables that affect products in stock (such as density and humidity). This study is updated periodically to include new measurement technologies and the results from previous financial periods.

Inventories of raw materials, supplies, materials and parts are recorded at the lower of acquisition cost or market value. The acquisition cost is calculated according to the average acquisition price method. Nonetheless, an estimate is made for each financial period of the potential lower value of that proportion of the inventory that consists of obsolete, defective or slow-moving materials. This provision reduces the value of the Company’s raw materials, supplies, materials and parts.

Obligations related to staff severance indemnities and pension commitments

Our obligations with respect to our employees are established in collective bargaining agreements and individual employment contracts. In the case of certain employees in the United States, our obligations are established through a pension plan, which was terminated in 2002.

These obligations are valued using an actuarial calculation that considers factors such as mortality rate, employee turnover, interest rates, retirement dates, effects related to increases in employees’ salaries, as well as the effects on variations in services derived from variations in the inflation rate.

Actuarial losses and gains that may be generated by variations in previously defined obligations are directly recorded in profit or loss for the year.

Actuarial losses and gains originating from deviations between the estimate and the actual behavior of actuarial hypotheses or in the reformulation of established actuarial hypotheses are recorded in equity.

The discount rate used for calculating obligations outside the United States was 5.1% and 4.5% for the periods ended as of December 31, 2017 and 2016, respectively.

The Company’s subsidiary SQM North America has established pension plans for its retired employees that are calculated by measuring the projected obligation using a net salary progressive rate net of adjustments for inflation, mortality and turnover assumptions, deducting the resulting amounts at present value using a 3.75% interest rate for 2017 and 4.5% for 2016. The net balance of this obligation is presented under the “Provisions for employee benefits, non-current” line item.

Mining development costs

Mine exploration costs and stripping costs to maintain production of mineral resources extracted from operating mines are considered variable production costs and are included in the cost of inventory produced during the period. Mine development costs at new mines, and major development costs at operating mines outside existing areas under extraction that are expected to benefit future production, are capitalized under “other long-term assets” and amortized using a units-of-production method over the associated proven and probable reserves. We determine our proven and probable reserves based on drilling, brine sampling and geostatistical reservoir modeling in order to estimate mineral volume and composition.

All other mine exploration costs, including expenses related to low grade mineral resources rendering reserves that are not economically exploitable, are charged to the statement of income in the period in which they are incurred.

| 71 |

Asset value impairment

We assess on an annual basis any impairment on the value of buildings, plant and equipment, intangible assets, goodwill and investments accounted for using the equity method of accounting in accordance with IAS 36 “Impairment of Assets.” Assets to which this method applies are:

| · | investments recognized using the equity method of accounting;

| · | property, plant and equipment;

| · | intangible assets and

| · | goodwill.

Assets are reviewed for impairment as to the existence of any indication that the carrying value is lower than the recoverable amount. If such an indication exists, the asset recoverable amount is calculated in order to determine the extent of the impairment, if any. In the event that the asset does not generate any cash flows independent from other assets, we determine the recoverable amount of the cash generating unit to which this asset belongs according to the corresponding business segment (specialty plant nutrients, iodine and derivatives, lithium and derivatives, potassium, industrial chemicals and other products and services.)

We conduct impairment tests on intangible assets and goodwill with indefinite useful lives on an annual basis and every time there is indication of impairment. If the recoverable value of an asset is estimated at an amount lower than its carrying value, the latter decreases to its recoverable amount.

The results of the impairment tests the Company has performed on its primary intangible assets demonstrated that there was no need for the Company to make any accounting adjustments to such assets. These impairment tests were performed using conservative scenarios. For more information, see Note 13.1 to our Consolidated Financial Statements.

We have recognized impairment events derived from the following:

As a result of the rain storms that affected the Tocopilla Zone at the beginning of August 2015, SQM S.A. confirmed the existence of damages in several zones in the railway between the sites Coya Sur and Tocopilla. SQM has performed several internal and external studies with the purpose of determining the costs and terms necessary to repair the damages in the railway.

Consequently, SQM has adjusted the value of the assets associated with the railway (fixed equipment, facilities and rolling equipment), which has translated into a charge of approximately US$32 million which are reflected in the line other expenses by function in the consolidated statement of income for 2016.

On September 22, 2015, the Company decided to close the mining operations at the Pedro de Valdivia site and a portion of such site’s industrial operations. This decision has been made because the Company has continued to increase its production capacity of iodine and nitrate salts in its industrial mining operations at the Nueva Victoria site and has reduced its production costs to meet sales forecasts and increase its current worldwide market share in the iodine market. The Company recognized the impairment effect of US$58 million in the consolidated statement of income for 2015.

Financial derivatives and hedging transactions

Derivatives are recognized initially at fair value as of the date on which the derivatives contract is signed and, they are subsequently assessed at fair value. The method for recognizing the resulting gain or loss depends on whether the derivative has been designated as an accounting hedge instrument and, if so, it depends on the type of hedging, which may be as follows:

| 72 |

a) Fair value hedge of assets and liabilities recognized (fair value hedges),

b) Hedging of a single risk associated with an asset or liability recognized or a highly probable forecast transaction (cash flow hedge).

At the beginning of the transaction, the Company documents the relationship that exists between hedging instruments and those items hedged, as well as their objectives for risk management purposes and the strategy to conduct different hedging operations.

The Company also documents its evaluation both at the beginning and at the end of each period if the derivatives used in hedging transactions are highly effective to offset changes in the fair value or in cash flows of hedged items.

The fair value of derivative instruments used for hedging purposes is shown in Note 10.3 (hedging assets and liabilities) to our Consolidated Financial Statements. Changes in the cash flow hedge reserve are classified as a non-current asset or liability if the remaining expiration period of the hedged item is more than 12 months, and as a current asset or liability if the remaining expiration period of the entry is less than 12 months.

Derivatives that are not designated or do not qualify as hedging derivatives are classified as current assets or liabilities, and changes in the fair value are directly recognized through profit or loss.

a. Fair value hedge

Changes in the fair value of derivatives that are designated and qualify as fair value hedges are recorded in profit or loss, together with any changes in the fair value of the hedged asset or liability that are attributable to the hedged risk. The gain or loss relating to the effective portion of interest rate swaps that hedge fixed rate borrowings is recognized in profit or loss within finance costs, together with changes in the fair value of the hedged fixed rate borrowings attributable to interest rate risk. The gain or loss relating to the ineffective portion is recognized in profit or loss within other income or other expenses. If the hedge no longer meets the criteria for hedge accounting, the adjustment to the carrying amount of a hedged item for which the effective interest method is used is amortized to profit or loss over the period to maturity using a recalculated effective interest rate.

b. Cash flow hedge

The portion of the derivative instruments used to mitigate cash flow fluctuations related to sales revenue or expenses is recognized in gross margin as a cost or undistributed revenue. The accrued portion of these instruments is recognized in other income or expenditure.

5.A. Operating Results

Introduction

The following discussion should be read in conjunction with the Company’s Consolidated Financial Statements. Certain calculations (including percentages) that appear herein have been rounded.

Our Consolidated Financial Statements are prepared in accordance with IFRS standards and prepared in U.S. dollars. The U.S. dollar is the primary currency in which we operate.

We operate as an independent corporation. Nonetheless we are a “controlled corporation,” as that term is defined under Chilean law. See “Item 7.A. Major Shareholders.”

| 73 |

Overview of Our Results of Operations

We divide our operations into the following business lines:

| · | the production and sale of specialty plant nutrients;

| · | the production and sale of iodine and its derivatives;

| · | the production and sale of lithium and its derivatives;

| · | the production and sale of potassium, including potassium chloride and potassium sulfate;

| · | the production and sale of industrial chemicals, principally industrial nitrates and solar salts and

| · | the purchase and sale of other commodity fertilizers for use primarily in Chile.

We sell our products through three primary channels: our own sales offices, a network of distributors and, in the case of our fertilizer products, through Yara International ASA’s (“Yara”) distribution network in countries where its presence and commercial infrastructure are larger than ours. Similarly, in those markets where our presence is larger, both our specialty plant nutrients and Yara’s are marketed through our offices.

Factors Affecting Our Results of Operations

Our results of operations substantially depend on:

| · | trends in demand for and supply of our products, including global economic conditions, which impact prices and sales volumes;

| · | efficient operations of our facilities, particularly as some of them run at production capacity;

| · | our ability to accomplish our capital expenditures program in a timely manner;

| · | the levels of our inventories;

| · | trends in the exchange rate between the U.S. dollar and Chilean peso, as a significant portion of the cost of sales is in Chilean pesos, and trends in the exchange rate between the U.S. dollar and the euro, as a significant portion of our sales is denominated in euros and

| · | energy, logistics, raw materials, labor and maintenance costs.

Impact of Foreign Exchange Rates

We transact a significant portion of our business in U.S. dollars, which is the currency of the primary economic environment in which we operate and is our financial currency for financial reporting purposes. A significant portion of our costs is related to the Chilean peso as most of our operations occur in Chile, and therefore an increase or decrease in the exchange rate between the Chilean peso and the U.S. dollar affects our costs of production. Additionally, as an international company operating in Chile and several other countries, we transact a portion of our business and have assets and liabilities in Chilean pesos and other non-U.S. dollar currencies, such as the Euro, the South African Rand and the Mexican peso. As a result, fluctuations in the exchange rate of such currencies to the U.S. dollar may affect our financial condition and results of operations. See Note 22 to our Consolidated Financial Statements.

We monitor and attempt to balance our non-dollar assets and liabilities position, including through foreign exchange contracts and other hedging instruments, to minimize our exposure to foreign exchange rate risk. As of December 31, 2017, for hedging purposes we had open contracts to buy U.S. dollars and sell euros for approximately US$33.31 million (EUR27.5 million) and sell South African rand for approximately US$19.96 million (ZAR276.5 million), as well as forward exchange contracts to sell U.S. dollars and buy Chilean pesos for US$84.0 million (Ch$51,639 million). All of our UF and Chilean pesos bonds were hedged with cross-currency swaps to the U.S. dollar for approximately US$250 million as of December 31, 2017.

In addition, we had open forward exchange contracts to buy U.S. dollars and sell Chilean pesos to hedge our time deposits in Chilean pesos for approximately US$550 million (Ch$351,416 million).

Results of Operations – 2017 compared to 2016

Revenues

Revenues increased by 11.2% to US$2,157.3 million in 2017 from US$1,939.3 million in 2016. The main factors that caused the increase in revenues and variations in different product lines are described below.

Specialty Plant Nutrition

Specialty plant nutrition revenues increased 11.8% to US$697.3 million in 2017 from US$623.9 million in 2016. Set forth below are sales volume data for the specified years by product category in this product line:

(in Th. MT) |  | 2017 |  |  | 2016 |  |  | % Change |
Potassium nitrate and sodium potassium nitrate |  |  | 601.4 |  |  |  | 475.8 |  |  |  | 26 | %
Specialty blends |  |  | 209.0 |  |  |  | 213.5 |  |  |  | -2 | %
Other specialty plant nutrients (*) |  |  | 129.1 |  |  |  | 127.2 |  |  |  | 2 | %
Sodium nitrate |  |  | 26.7 |  |  |  | 24.4 |  |  |  | 10 | %

* Includes trading of other specialty fertilizers.

We sell various products within the specialty plant nutrition business line, and most of our specialty fertilizers are sold as either field fertilizers or water soluble fertilizers. Our sales volumes in this business line increased 14.9% in 2017 compared to 2016 primarily due to demand growth and limited supply from our competitors.

Average prices in the specialty plant nutrition business line were US$722/MT in 2017, slightly lower than US$742/MT in 2016.

Iodine and Derivatives

Iodine and derivatives revenues increased 9.1% to US$252.1 million in 2017 from US$231.1 million in 2016. Set forth below are sales volume data for the specified years:

(in Th. MT) |  | 2017 |  |  | 2016 |  |  | % Change |
Iodine and derivatives |  |  | 12.7 |  |  |  | 10.2 |  |  |  | 24 | %

Our sales volumes in this business line increased by approximately 24% compared to 2016, primarily as a result of higher demand due to new applications of iodine in the specialty plastics and carbon energy plants emission control industries.

However, average prices during 2017 continued to face downward pressure. Our average price for the year was US$20/kilogram, a decrease of over 12% compared to 2016.

Lithium and Derivatives

Lithium and derivatives revenues increased 25.3% to US$644.6 million in 2017 from US$514.6 million in 2016. Set forth below are sales volume data for the specified years:

(in Th. MT) |  | 2017 |  |  | 2016 |  |  | % Change |
Lithium and derivatives |  |  | 49.7 |  |  |  | 49.7 |  |  |  | 0 | %

| 76 |

The lithium market continued its strong growth in 2017, with total lithium demand increasing by nearly 17% according to our estimates. Supply did not keep the same pace, and therefore market conditions remained tight.

Average prices in this business line increased 25% compared to average prices during 2016, reaching almost US$13,000/MT compared to average prices of approximately US$10,400/MT in 2016.

Potassium

Potassium revenues decreased 5.9% to US$379.3 million in 2017 from US$403.3 million in 2016. Set forth below are sales volume data for the specified years:

(in Th. MT) |  | 2017 |  |  | 2016 |  |  | % Change |
Potassium chloride and potassium sulfate |  |  | 1,344.3 |  |  |  | 1,534.7 |  |  |  | -12 | %

Our revenues in the potassium chloride and potassium sulfate business line were impacted by reduced sales volumes in 2017. As anticipated, sales volumes decreased over 12% during 2017 as we focused our production efforts in the Salar de Atacama on increasing lithium yields. The potassium chloride demand increased an additional 4 million metric tons in 2017, reaching almost 63 million metric tons. As result, potash prices increased slightly during the year. Average prices in the potassium chloride and potassium sulfate business line increased approximately 7.4% during 2017 when compared to 2016, reaching US$282/MT.

Industrial Chemicals

Industrial chemicals revenues increased 30.2% to US$135.6 million in 2017 from US$104.1 million in 2016. Set forth below are sales volume data for the specified years by product category:

(in Th. MT) |  | 2017 |  |  | 2016 |  |  | % Change |
Industrial chemicals |  |  | 167.6 |  |  |  | 128.9 |  |  |  | 30 | %

Revenues in the industrial chemicals business line increased as a result of higher sales volumes. These higher sales volumes were primarily related to increased sales volumes of solar salts, which totaled almost 88,000 metric tons this year, in line with our estimated volumes for the year.

Other Products and Services

Revenues from sales of other commodity fertilizers and other income decreased 22% to US$48.5 million in 2017 from US$62.2 million in 2016, primarily due to reduced sales volumes.

Cost of Sales

Our overall cost of sales increased 5.0% to US$1,394.8 million in 2017, which represented 64.7% of revenues, from US$1,328.3 million in 2016, which represented 68.5% of revenues. The main factors that caused the increase in cost of sales and variations in different product lines are described below.

Specialty Plant Nutrition

Specialty plant nutrition cost of sales increased 16.2% to US$555.4 million in 2017 from US$478.1 million in 2016, as a result of increased sales volumes in 2017. The average cost of sales in the specialty plant nutrition business line was US$575/MT in 2017, slightly higher than US$569/MT in 2016.

| 77 |

Iodine and Derivatives

Iodine and derivatives cost of sales increased 4.4% to US$199.8 million in 2017 from US$191.3 million in 2016, as a result of increased sales volumes in 2017. The average cost of sales in the iodine and derivatives business line was US$16/kilogram in 2017, a decrease of almost 16% from US$19/kilogram in 2016. We believe that we are the lowest cost producer of iodine and the cost reduction achieved in 2017 is a result of concentrating all of our production in the modern and efficient production facilities at Nueva Victoria after the closure of Pedro de Valdivia plant.

Lithium and Derivatives

Lithium and derivatives cost of sales increased 7.8% to US$189.2 million in 2017 from US$175.6 million in 2016, primarily as result of higher lease payments to Corfo, and operating our production plant at full capacity. The average cost of sales in the lithium and derivatives business line was US$3,808/MT in 2017, an increase of almost 7.7% from US$3,536/MT in 2016.

Potassium

Potassium cost of sales decreased 12.7% to US$313.7 million in 2017 from US$359.5 million in 2016, as a result of decreased sales volumes. The average cost of sales in the potassium business line was US$233/MT in 2017, a slight decrease from US$234/MT in 2016.

Industrial Chemicals

Industrial chemicals cost of sales increased 36.2% to US$91.8 million in 2017 from US$67.4 million in 2015, as a result of increased sales of solar salts. The average cost of sales in the industrial chemicals business line was US$547/MT in 2017, an increase of 4.7% from US$523/MT in 2016. This increase in cost was a result of a change in product mix.

Gross Profit

Gross profit increased 24.8% to US$762.5 million in 2017, which represented 35.3% of revenues, from US$611.0 million in 2016, which represented 31.5% of revenues. As discussed above, this increase is attributable to the increase in revenues as a result of significantly higher lithium prices, higher sales volumes in specialty plant nutrition, iodine and derivatives, and solar salts. A reduction in cost of sales from 68.5% of 2016 revenues to 64.7% of 2017 revenues also contributed to an increase in gross profit.

Other Income

Other income increased 17.3% to US$17.8 million in 2017, which represented 0.8% of revenues, from US$15.2 million in 2016, which represented 0.8% of revenues. As a percentage of revenues, other income remained very similar between 2017 and 2016.

Administrative Expenses

Administrative expenses increased 14.4% to US$101.2 million in 2017, which represented 4.7% of revenues, from US$88.4 million in 2016, which represented 4.6% of revenues, due to increased revenues.

| 78 |

Other Expenses

Other expenses decreased 31.3% to US$61.6 million in 2017, which represented 2.9% of revenues, from US$89.7 million in 2016, which represented 4.6% of revenues. This decrease was primarily attributable to a one-time charge for impairment related to the closing of the train between Coya Sur and Tocopilla of approximately US$32.8 million and a charge of approximately US$30.5 million related to the Company's agreement with the DOJ and the administrative cease and desist order issued by the SEC, both in 2016. The decrease in other expenses seen in 2017 was partially offset by a charge of approximately US$20.4 million relating to payment made by our subsidiary SQM Salar S.A. to Corfo after entering into the Corfo Arbitration Agreement.

Other Gains (Losses)

Other gains (losses) decreased to a gain of US$0.5 million in 2017, which represented 0.03% of revenues, from a gain of US$0.7 million in 2016, which represented 0.04% of revenues.

Finance Income

Finance income increased 33.3% to US$13.5 million in 2017, which represented 0.6% of revenues, from US$10.1 million in 2016, which represented 0.5% of revenues, due to higher interest rates earned on our investments and higher investments volumes during the year.

Finance Expenses

Finance expenses decreased 12.8% to US$50.1 million in 2017, which represented 2.3% of revenues, from US$57.5 million in 2016, which represented 3.0% of revenues, due to decreased levels of debt that we had during 2017.

Equity Income of Associates and Joint Ventures Accounted for Using the Equity Method

Equity income of associates and joint ventures accounted for using the equity method increased 10.8% to US$14.5 million in 2017, which represented 0.7% of revenues, from US$13.0 million in 2016, which represented 0.7% of revenues.

Foreign Currency Exchange Differences

Losses from foreign currency exchange differences amounted to US$1.3 million in 2017, which represented 0.06% of revenues, compared with a profit of US$0.5 million in 2016, which represented 0.2% of revenues. A significant portion of our costs is related to the Chilean peso as most of our operations occur in Chile. Because the U.S. dollar is our functional currency, we are subject to currency fluctuations. We aim to mitigate this impact through an active hedging program. During 2017, the Chilean peso appreciated 8.0% against the U.S. dollar.

Profit Before Taxes

Profit before taxes increased by US$179.7 million, or 43.3%, to US$594.6 million in 2017 from US$414.9 million in 2016. This increase was primarily attributable to increase in revenues by US$218.0 million, a decrease in financial expenses by US$7.4 million and a decrease in other expenses by US$28.1 million, partially offset by an increase in cost of sales by US$66.5 million, each of the reasons described above.

| 79 |

Income Tax Expense

Income tax expenses increased 25.0% to US$166.2 million in 2017, representing an effective tax rate of 27.9%, compared to US$133.0 million in 2016, representing an effective tax rate of 32.0%. The effective Chilean corporate tax rate was 24.0% during 2016 and increased to 25.5% during 2017. The difference between the statutory and effective tax rates was primarily due to a decrease related to tax effect of tax rates outside Chile and non-deductible expenses as detailed in the Note 27.3 d.11 to our Consolidated Financial Statements.

Profit for the Year

Profit for the year increased 53.7% to US$427.7 million in 2017 from US$278.3 million in 2016, primarily as a result of significantly higher lithium prices and increased sales volumes in specialty plant nutrients, iodine and derivatives and industrial chemicals business lines.

Results of Operations – 2016 compared to 2015

Revenues

Revenues increased by 12.2% to US$1,939.3 million in 2016 from US$1,728.3 million in 2015.

The main factors that caused the increase in revenues and variations in different product lines are described below.

Specialty Plant Nutrition

Specialty plant nutrition revenues decreased 4.4% to US$623.9 million in 2016 from US$652.3 million in 2015. Set forth below are sales volume data for the specified years by product category in this product line:

(in Th. MT) |  | 2016 |  |  | 2015 |  |  | % Change |
Potassium nitrate and sodium potassium nitrate |  |  | 475.8 |  |  |  | 493.6 |  |  |  | -4 | %
Specialty blends |  |  | 213.5 |  |  |  | 203.9 |  |  |  | 5 | %
Other specialty plant nutrients (*) |  |  | 127.2 |  |  |  | 108.4 |  |  |  | 17 | %
Sodium nitrate |  |  | 24.4 |  |  |  | 26.0 |  |  |  | -6 | %

* Includes trading of other specialty fertilizers.

We sell various products within the specialty plant nutrition business line, and most of our specialty fertilizers are sold as either field fertilizers or water soluble fertilizers. Our sales volumes in the field fertilizer market decreased in 2016 compared to 2015 due to decreased demand.

Average prices in the specialty plant nutrition business line were US$742/MT in 2016, slightly lower than US$784/MT in 2015.

Iodine and Derivatives

Iodine and derivatives revenues decreased 12.0% to US$231.1 million in 2016 from US$262.6 million in 2015. Set forth below are sales volume data for the specified years:

(in Th. MT) |  | 2016 |  |  | 2015 |  |  | % Change |
Iodine and derivatives |  |  | 10.2 |  |  |  | 9.3 |  |  |  | 9 | %

| 80 |

In the iodine market, global demand grew by 1% in 2016 as a result of nominal growth in the LED and LCD markets. Our sales volumes in this business line increased by approximately 9% compared to 2015, increasing our participation in the market.

However, average prices during 2016 continued to face downward pressure. Our average price for the year was US$23/kilogram, a decrease of over 19% compared to 2015.

Lithium and Derivatives

Lithium and derivatives revenues increased 130.8% to US$514.6 million in 2016 from US$223.0 million in 2015. Set forth below are sales volume data for the specified years:

(in Th. MT) |  | 2016 |  |  | 2015 |  |  | % Change |
Lithium and derivatives |  |  | 49.7 |  |  |  | 38.7 |  |  |  | 28 | %

World demand in the lithium market continued to grow at robust levels in 2016, around 14%. This demand growth is led by uses related to batteries, specifically batteries related to electric vehicles. In 2016, batteries accounted for almost 53% of the total lithium market, including electric cars. Introduction of new lithium supply was delayed in 2016, and only a minimal amount of new production was offered for sale.

Average prices in this business line increased significantly in 2016, with average prices reaching nearly US$10,400/MT, 80% higher than average prices of approximately US$5,800/MT in 2015. Our sales volumes in 2016 increased more than 28% compared to sales volumes in 2015.

Potassium

Potassium revenues decreased 6.3% to US$403.3 million in 2016 from US$430.6 million in 2015. Set forth below are sales volume data for the specified years:

(in Th. MT) |  | 2016 |  |  | 2015 |  |  | % Change |
Potassium chloride and potassium sulfate |  |  | 1,534.7 |  |  |  | 1,241.8 |  |  |  | 24 | %

The potassium chloride market experienced little change in global demand in 2016 compared to 2015.

However, market prices in 2016 were significantly lower than in 2015 due to slight demand growth and increased supply in the market. Our average price in this business line, including both potassium chloride and potassium sulfate, was US$263/MT in 2016, a decrease of 24.2% compared to the average price of US$347/MT in 2015.

This decline in our average price was partially offset by the increase in our sales volumes. Our sales volumes in this business line increased 24% in 2016 compared to 2015. This increase in sales volumes, in 2016, was attributable to lower sales volumes in 2015 due to production and shipping problems.

| 81 |

Industrial Chemicals

Industrial chemicals revenues increased 6.8% to US$104.1 million in 2016 from US$97.6 million in 2015. Set forth below are sales volume data for the specified years by product category:

(in Th. MT) |  | 2016 |  |  | 2014 |  |  | % Change |
Industrial chemicals |  |  | 128.9 |  |  |  | 126.1 |  |  |  | 2 | %

Industrial chemicals demand for traditional applications decreased in 2016 compared to 2015, as did our sales volumes related to traditional uses due to increased sales of solar salts. Solar salt sales volumes in 2016 reached just over 57,000 metric tons, an increase of over 53% compared to 2015.

Other Products and Services

Revenues from sales of other commodity fertilizers and other income decreased 0.1% to US$62.2 million in 2016 from US$62.3 million in 2015, due to lower prices in the fertilizer market.

Cost of Sales

Our overall cost of sales increased 12.0% to US$1,328.3 million in 2016, which represented 69% of revenues, from US$1,185.6 million in 2015, which represented 69% of revenues. The main factors that caused the increase in cost of sales and variations in different product lines are described below.

Specialty Plant Nutrition

Specialty plant nutrition cost of sales increased 3.7% to US$478.1 million in 2016 from US$461.0 million in 2015, as a result of a product mix change. The average cost of sales in the specialty plant nutrition business line was US$568/MT in 2016, slightly higher than US$554/MT in 2015.

Iodine and Derivatives

Iodine and derivatives cost of sales increased 3.7% to US$191.3 million in 2016 from US$184.6 million in 2015, as a result of increased sales volumes in 2016. The average cost of sales in the iodine and derivatives business line was US$19/kilogram in 2016, a decrease of almost 5% from US$20/kilogram in 2015. We believe we are the lowest cost producer of iodine. The vast majority of our production capacity comes from our most efficient plant in Nueva Victoria.

Lithium and Derivatives

Lithium and derivatives cost of sales increased 60.5% to US$175.6 million in 2016 from US$109.4 million in 2015, as result of increased sales volumes, higher lease payments to Corfo, and operating our production plant close to full capacity. The average cost of sales in the lithium and derivatives business line was US$3,536/MT in 2016, an increase of almost 25% from US$2,825/MT in 2015.

Potassium

Potassium cost of sales increased 18.4% to US$359.5 million in 2016 from US$303.6 million in 2015, as a result of increased sales volumes.] The average cost of sales in the potassium business line was US$234/MT in 2016, a decrease of almost 4% from US$245/MT in 2015.

Industrial Chemicals

Industrial chemicals cost of sales decreased 5.4% to US$67.4 million in 2016 from US$71.3 million in 2015, as a result of decreased sales of potassium nitrate for industrial use that has a higher average cost of sales. The average cost of sales in the industrial chemicals business line was US$523/MT in 2016, a decrease of almost 8% from US$565/MT in 2015. This decrease in cost was a result of a change in product mix.

| 82 |

Gross Profit

Gross profit increased 12.6% to US$611.0 million in 2016, which represented 31.5% of revenues, from US$542.7 million in 2015, which represented 31.4% of revenues. As discussed above, this increase is attributable to the increase in revenues as a result of higher sales volumes in all of our business lines, and significantly higher average prices in the lithium and derivatives business line, partially offset by the increase in cost of sales as a result of higher revenues, as costs as a percentage of sales did not change between 2016 and 2015.

Other Income

Other income decreased 0.6% to US$15.2 million in 2016, which represented 0.8% of revenues, from US$15.3 million in 2015, which represented 0.9% of revenues. As a percentage of revenues, other income remained very similar between 2016 and 2015.

Administrative Expenses

Administrative expenses increased 1.8% to US$88.4 million in 2016, which represented 4.6% of revenues, from US$86.8 million in 2015, which represented 5.0% of revenues. We were able to reduce our costs as a percentage of revenues through increased efficiencies.

Other Expenses

Other expenses decreased 15.7% to US$89.7 million in 2016, which represented 4.6% of revenues, from US$106.4 million in 2015, which represented 6.2% of revenues. This decrease was primarily attributable to a one-time charge of US$57.7 million in 2015, for impairment and severance indemnities related to the restructuring of our operations in Pedro de Valdivia.

Other Gains (Losses)

Other gains (losses) decreased to a gain of US$0.7 million in 2016, which represented 0.04% of revenues, from a gain of US$3.8 million in 2015, which represented 0.2% of revenues.

Finance Income

Finance income decreased 8.8% to US$10.5 million in 2016, which represented 0.5% of revenues, from US$11.6 million in 2015, which represented 0.7% of revenues, due to lower interest rates earned on our investments.

Finance Expenses

Finance expenses decreased 17.7% to US$57.5 million in 2016, which represented 3.0% of revenues, from US$69.9 million in 2015, which represented 4.0% of revenues, due to decreased levels of debt that we incurred at the end of 2016.

Equity Income of Associates and Joint Ventures Accounted for Using the Equity Method

Equity income of associates and joint ventures accounted for using the equity method increased 26.4% to US$13.0 million in 2016, which represented 0.7% of revenues, from US$10.3 million in 2015, which represented 0.6% of revenues.

| 83 |

Foreign Currency Exchange Differences

Losses from foreign currency exchange differences decreased 104% to US$0.5 million in 2016, which represented 0.02% of revenues, from US$12.4 million in 2015, which represented 0.7% of revenues. A significant portion of our costs is related to the Chilean peso as most of our operations occur in Chile. Because the U.S. dollar is our functional currency, we are subject to currency fluctuations. We aim to mitigate this impact through an active hedging program. During 2016, the Chilean peso appreciated 6.0% against the U.S. dollar.

Profit Before Taxes

Profit before taxes increased by US$79.7 million, or 25.9%, to US$414.9 million in 2016 from US$308.3 million in 2015. This increase was primarily attributable to increase in revenues by US$211 million and a decrease in financial expenses by US$12.4 million, partially offset by an increase in cost of sales by US$142.7 million, each for the reasons described above.

Income Tax Expense

Income tax expenses increased 58.7% to US$133.0 million in 2016, representing an effective tax rate of 32.0%, compared to US$83.8 million in 2015, representing an effective tax rate of 27.2%. The Chilean corporate tax rate was 22.5% during 2015 and increased to 24.0% during 2016. The difference between the statutory and effective tax rates was due primarily to royalty taxes on income.

Profit for the Year

Profit for the year increased 25.6% to US$281.9 million in 2016 from US$224.5 million in 2015 primarily as a result of increased volumes in all business lines, and significantly higher prices in the lithium business line in 2016 compared to 2015.

5.B. Liquidity and Capital Resources

As of December 31, 2017, we had US$989.7 million of cash and cash equivalents and time deposits. In addition, as of December 31, 2017, we had US$248 million of unused uncommitted working capital credit lines.

Shareholders’ equity decreased to US$2,247.5 million as of December 31, 2017 from US$2,307.3 million as of December 31, 2016. Our ratio of total liabilities to total equity (including non-controlling interest) on a consolidated basis increased to 0.91 as of December 31, 2017 from 0.83 as of December 31, 2016.

We evaluate from time to time our cash requirements to fund capital expenditures, dividend payouts and increases in working capital, but we believe our working capital is sufficient for our present requirements. As debt requirements also depend on the level of accounts receivable and inventories, we cannot accurately determine the amount of debt we will require nor are our requirements typically seasonal.

The table below shows our cash flows for 2017, 2016 and 2015:

(in millions of US$) |  | 2017 |  |  | 2016 |  |  | 2015 |
Net cash from operating activities |  |  | 758.3 |  |  |  | 633.7 |  |  |  | 427.3 |
Net cash used in financing activities |  |  | (411.9 | ) |  |  | (816.4 | ) |  |  | (180.3 | )
Net cash from (used in) investing activities |  |  | (248.1 | ) |  |  | 162.4 |  |  |  | (69.8 | )
Effects of exchange rate fluctuations on cash and cash equivalents |  |  | 17.5 |  |  |  | 7.8 |  |  |  | (4.5 | )
Net increase (decrease) in cash and cash equivalents |  |  | 115.8 |  |  |  | (12.6 | ) |  |  | 172.7 |

| 84 |

We operate a capital-intensive business that requires significant investments in revenue-generating assets. Our past growth strategies have included purchasing production facilities and equipment and the improvement and expansion of existing facilities. Funds for capital expenditures and working capital requirements have been obtained from net cash from operating activities, borrowing under credit facilities and issuing debt securities.

The Board of Directors approved a capital expenditures plan for 2018 of approximately US$517 million in connection with investments to be made in Chile and abroad. The 2018 capital investment program is primarily focused on the maintenance and expansion of our production facilities as well as investment in new projects. Our 2018 capital investment program does not require external financing but we evaluate from time to time whether to access capital markets in order to optimize our financial position. See “Item 4.A. History and Development of the Company—Capital Expenditure Program.”

Our other major use of funds is for dividend distributions. We paid dividends of US$370 million and US$398 million during 2017 and 2016, respectively. Our 2017 dividend policy, as disclosed at our 2017 annual general shareholders’ meeting, is to pay a percentage of our net income that is determined as per following financial parameters:

(i) 100% of the 2017 net income, when the following financial parameters are met: (a) the total sum of cash and cash equivalent, and other current financial assets (“Cash”) divided by the total sum of the current financial liabilities (“Current Financial Liabilities”) is equal to or greater than 2.5 times, and (b) the total sum of the current liabilities and the non-current liabilities (“Total Liabilities”) divided by the total sum of the equity (“Equity”) is equal to or less than 1.1 times.

(ii) 80% of the 2017 net income when the following financial parameters are met: (a) Cash divided by Current Financial Liabilities is equal to or greater than 2.0 times, and (b) the total sum of the Total Liabilities divided by the total Equity is equal to or less than 1.2 times.

(iii) 60% of the 2017 net income when the following financial parameters are met: (a) Cash divided by Current Financial Liabilities is equal to or greater than 1.5 times, and (b) Total Liabilities divided by Equity is equal to or less than 1.3 times.

If none of the foregoing financial parameters are met, the Company shall distribute and pay, as a final dividend, and in favor of the respective shareholders, 50% of the 2017 net income.

On May 17, 2017, the Board of Directors agreed to pay and distribute on June 15, 2017 a provisional dividend of US$103 million, equivalent to US$0.39222 per share, to be charged against the 2017 net income.

On August 23, 2017, the Board of Directors agreed to pay and distribute on September 14, 2017 a provisional dividend of US$101 million, equivalent to US$0.38432 per share, to be charged against the 2017 net income.

On November 22, 2017, the Board of Directors agreed to pay and distribute on December14, 2017 a provisional dividend of US$113 million, equivalent to US$0.42879 per share, to be charged against the 2017 net income.

| 85 |

On March 28, 2018, the Board of Directors agreed to recommend to the shareholders the payment of a definitive dividend representing 100% of the 2017 net income and a special dividend (dividendo eventual) in the amount of US$100 million. The payment of these dividends will be presented for consideration at the Annual General Shareholders’ Meeting held on April 27, 2018. Therefore, and subject to the approval at the shareholders’ meeting, the Company shall pay a final dividend of US$1,62501 per share to be charged against the 2017 net income and a special dividend of US$0.37994 per share to be charged against the retained earnings. The amount of US$1.20533 per share must be deducted from the final dividend, as it was already paid in the form of interim dividends. The balance, in the amount of US$0.41968 per share, and a special dividend of US$0.37994 per share shall be paid and distributed to Company´s shareholders, pending shareholders´ approval, on May 10, 2018.

The dividend policy for 2018 is expected to be announced at the Annual Shareholders’ Meeting held on April 27, 2018.

Financing Activities

Our current ratio, defined as current assets divided by current liabilities, decreased to 3.29 as of December 31, 2017 from 4.02 as of December 31, 2016. The following table shows key information about our outstanding long- and short-term debt as of December 31, 2017.

Debt Instrument(1) |  | Interest Rate |  |  | Issue Date |  | Maturity Date |  | Amortization

(1) UF- denominated bonds are fully hedged to U.S. dollars with cross-currency swaps.

As of December 31, 2017, we had total financial debt of US$1,203 million compared to US$1,215 million as of December 31, 2016. Considering the effects of financial derivatives, our total financial debt amounted to US$1,252 million as of December 31, 2017 and US$1,273 million as of December 31, 2016. Of the total debt as of December 31, 2017, US$223 million was short-term debt. All of our UF local bonds were hedged with cross-currency swaps to the U.S. dollar as of December 31, 2017.

As of December 31, 2017, all of our long-term debt, including the current portion, was denominated in U.S. dollars, and all our UF-denominated bonds were hedged with cross-currency swaps to the U.S. dollar.

The financial covenants related to our debt instruments include: (i) limitations on the ratio of total liabilities to equity (including non-controlling interest) on a consolidated basis, and (ii) minimum production assets. We believe that the terms and conditions of our debt agreements are standard and customary.

The following table shows the maturities of our long-term debt by year as of December 31, 2017 (in millions of US dollars):

Maturity(1) |  | Amount |
2018 |  |  | 163.0 |
2019 |  |  | 7.9 |
2020 |  |  | 265.9 |
2021 |  |  | 15.9 |
2022 and thereafter |  |  | 750.1 |
Total |  |  | 1,202.8 |

(1) Only the principal amount has been included. For the UF-denominated local bonds, the amounts presented reflect the real U.S. dollar obligation as of December 31, 2017 not including the effects of the cross currency swaps that hedge these bonds to the U.S. dollar and which had, as of December 31, 2017, a market value of US$5 million against SQM.

On April 5, 2018, we placed and sold on the Chilean stock market an issue of Series P bonds for the total amount of UF 3,000,000 (approximately US$135 million). The issued bonds (i) have a maturity date of January 15, 2028, (ii) will accrue interest at the rate of 3.25% per annum on the unpaid capital, expressed in UF, from January 15, 2018; and (iii) have an early redemption option from April 5, 2018.

Environmental and Occupational Safety and Health Projects

We spent US$20.6 million on environmental, safety and health projects in 2017. We have budgeted approximately US$17.5 million in 2018 for environmental, safety and health projects. This amount forms part of the capital expenditure program discussed above.

5.C. Research and Development, Patents and Licenses, etc.

One of the main objectives of our research and development team is to develop new processes and products in order to maximize the returns obtained from the resources that we exploit. Our research is performed by three different units, whose research topics cover all of the processes involved in the production of our products, including chemical process design, phase chemistry, chemical analysis methodologies and physical properties of finished products.

Our research and development policy emphasizes the following: (i) optimizing current processes in order to decrease costs and improve product quality through the implementation of new technology, (ii) developing higher-margin products from current products through vertical integration or different product specifications, (iii) adding value to inventories and (iv) using renewable energy in our processes.

Our research and development activities have been instrumental in improving our production processes and developing new value-added products. As a result, new methods of extraction, crystallization and finishing products have been developed. Technological advances in recent years have enabled us to improve process efficiency for the nitrate, potassium and lithium operations, improve the physical quality of our prilled products and reduce dust emissions and caking by applying specially designed additives to our products handled in bulk. Our research and development efforts have also resulted in new, value-added markets for our products. One example is the use of sodium nitrate and potassium nitrate as thermal storage in solar power plants.

We have patented several production processes for nitrate, iodine and lithium products. These patents have been filed mainly in the United States, Chile and in other countries when necessary. The patents used in our production processes include Chilean patent No. 47,080 for iodine (production of spherical granules of chemicals that sublime), Japanese patent No. 4,889,848 for nitrates (granular fertilizers) and patent Nos. 41,838 from Chile, 5393-B and 5391-B from Bolivia, AR001918B1 and AR001916B1 from Argentina and 5,676,916 and 5,939,038 from the U.S. for lithium (removal of boron from brines).

For the years ended December 31, 2017, 2016 and 2015, we invested US$6.4 million, US$11.0 million and US$4.4 million, respectively, in research and development activities.

5.D. Trend Information

Our revenues increased 11.2% to US$2,157.3 million in 2017 from US$1,939.3 million in 2016. Gross profit increased 24.8% to US$762.5 million in 2017, which represented 35.3% of revenues, from US$611.0 million in 2016, which represented 31.5% of revenues. Profit attributable to controlling interests increased 53.7% to US$427.7 million in 2017 from US$278.3 million in 2016.

| 87 |

Our sales volumes in the specialty plant nutrition business line increased 14.9% in 2017 compared to 2016, while average prices decreased by 2.7%. As a result, our revenues in this business line increased by 11.8%. Higher sales volumes seen during 2017 were due to demand growth and limited supply from our competitors. We expect to see similar sales volumes in 2018. We sell various products within this business line, and most of our specialty fertilizers are sold as either field fertilizers or water soluble fertilizers. Our strategy in this business line has been to focus primarily on the water soluble fertilizer market, which in general yields higher margins and has more growth potential. Average prices in this business line were slightly lower in 2017, and we expect average prices to be flat in 2018.

Our sales volumes in the iodine business line increased 24.4% in 2017. We also saw prices stabilize during the first half of the year and slightly improving in the second half of the year. Still, the average prices in 2017 were 12.3% lower than the average prices seen in 2016. Increased sales volumes compensated for lower prices resulting in an increase of 9.1% in our revenues for this business line. We believe that the pricing trend will continue into 2018 with average prices slightly higher than in 2017. According to our estimates, the global iodine demand grew slightly in 2017 reaching almost 35,300 MT and we increased our market share to over 35%. We expect to increase our iodine sales volumes in line with the market growth, maintaining our current market share.

We saw similar sales volumes in the lithium business line in 2017 compared to 2016. The lithium market continued its strong growth in 2017, with total demand growth reaching close to 17% according to our estimates. Supply did not keep the same pace, and therefore market conditions remained tight and prices increased significantly during the year. This pricing trend, given that the sales volumes stayed at the same level as in 2016, impacted our revenues for 2017 by almost US$130 million. Average prices in this business line increased another 25% compared to average prices seen during 2016. We believe that the market price could be almost 20% higher in the first half of 2018 compared to the fourth quarter of 2017. However, we expect that new projects could increase their supply in the second half of 2018 resulting in more stable or slightly lower average prices. Still, we expect averages prices to be higher in 2018 compared to the average prices seen in 2017. We believe that the worldwide lithium market could grow almost 20% in 2018, driven by the development of energy storage and batteries for electric vehicles.

Once the amendments to the Lease Agreement and Project Agreement with Corfo become effective, the higher lease payment rate will be applied to the revenues related to lithium. We expect to increase our sales volumes to almost 55,000 metric tons in 2018; however, we are not able to confirm whether the increased sales volumes combined with higher prices could offset the impact of higher lease payments on the gross margin of this business line.

Our sales volumes in the potassium business line decreased by 12.4% in 2017 compared to 2016, as we focused our production efforts in the Salar de Atacama on increasing lithium yields. Average prices in the potassium chloride and potassium sulfate business line increased approximately 7.4% during 2017 when compared to 2016, reaching US$282/MT. We believe that we could see a continued decrease in potassium chloride production during 2018 with sales volumes of approximately one million metric tons, as we are increasing our lithium production. The higher prices reflected the stronger global demand for potassium chloride in 2017, reaching almost 63 million metric tons. We believe that average prices for this business line could remain flat or show a slight growth in 2018.

Our sales volumes in the industrial chemicals product line increased 30.0% in 2017 compared to 2016, driven by higher sales volumes of solar salts. Solar salts sales depend on the ramp up of the concentrated solar power plants (CSP) projects and we expect our sales volumes in 2018 to be approximately 50,000 metric tons. During 2017, prices remained flat compared to 2016.

For the year ended December 31, 2017, the aggregate compensation paid to our 115 principal executives based in Chile was Ch$16,824 million. We do not disclose to our shareholders or otherwise make available to the public information as to the compensation of our individual executive officers.

We maintain incentive programs for our employees based on individual performance, company performance and short-term indicators. We provide executives with an annual and a long-term bonus plan payable in the first quarter of 2021 or the date of the executive´s resignation. Their incentives are based on target achievement, individual contribution to the Company’s operating results, the operating results and safety indexes of the Company. SQM also operates a compensation plan designed to retain its executives by providing bonuses linked to the Company’s share price.

As of December 31, 2017, we had a provision related to all of the incentive programs in the aggregate of US$28.9 million.

We do not maintain any pension or retirement programs for the members of the Board of Directors or our executive officers in Chile.

6.C. Board Practices

Information regarding the period of time each of SQM’s current Directors has served in his office is provided in the discussion of each member of the Board of Directors above in Item 6.A. Directors and Senior Managers.

The date of expiration of the term of the current Board of Directors is April 2020. The contracts of our executive officers are indefinite. The current Board of Directors was elected at the previous Annual Ordinary Shareholders’ Meeting held on April 28, 2017.

The members of the Board of Directors are remunerated in accordance with the information provided above in Item 6.B. Compensation. There are no contracts between SQM, or any of its subsidiaries, and the members of the Board of Directors providing for benefits upon termination of their term.

Directors’ Committee – Audit Committee

As required by Chilean Law, during 2017, we had a Directors’ Committee (Comité de Directores) composed of three Directors, which performs many of the functions of an audit committee. Under the NYSE corporate governance rules, the audit committee of a U.S. company must perform the functions detailed in the NYSE Listed Company Manual Rules 303A.06 and 303A.07. Non-U.S. companies are required to comply with Rule 303A.06 but are not at any time required to comply with Rule 303A.07.

Between January 1, 2017 and April 27, 2017, our Directors’ Committee was comprised of three Directors: Mr. Waitzer, Mr. Julio Rebolledo D. and Mr. Linneberg. Each of the three members met the NYSE independence requirements for audit committee members. According to Chilean independence requirements, Mr. Linneberg and Mr. Waitzer met the requirements for independence. On March 22, 2017, Julio Rebolledo D. informed the Board of Directors that he has decided to resign from his position as director of SQM effective April 27, 2017.

Since April 28, 2017, our Directors’ Committee was comprised of three Directors: Mr. Gerardo Jofré M., Mr. Fernando Massu T. and Ms. Joanne L. Boyes. Messrs. Jofré and Massu met the NYSE independence and Chilean independence requirements for audit committee members. Ms. Boyes, who was an executive officer of Nutrien (formerly PCS prior to the merger with Agrium Inc. on January 1, 2018) during her service on our Directors’ Committee, served as an observer on audit committee matters. See “Item 16D. Exemptions from the Listing Standards for Audit Committees.” On January 24, 2018, Ms. Boyes resigned from her position as director of SQM. On the same day, Mr. Darryl Stann was appointed as a director, replacing Ms. Boyes.

During 2017, the Directors’ Committee of SQM (the “Committee”) analyzed (i) the Company’s Unaudited Financial Statements and Reports; (ii) the Company’s Audited Financial Statements and Reports; (iii) the Reports and proposals of external auditors, accounts inspectors and independent risk rating agencies for the Company; (iv) the proposal to SQM’s Board of Directors about the external auditors and independent rating agencies that the Board could recommend to the respective shareholders’ meeting for their subsequent appointment; (v) the tax and other services, other than audit services, provided by the Company’s external auditors and its subsidiaries in Chile and abroad; (vi) the remuneration and compensation plans for the Company’s main executives; (vii) the information related to the Company’s operations as referred to in Title XVI of the Corporations Act; (viii) the report on internal control of the Company and (ix) the various matters referred to in the Chapter titled “Directors’ Committee” included in SQM’s Financial Statements at December 31, 2017.

Regarding the above, the Committee:

| (a) | Examined the information regarding the financial statements of SQM for the 2017 business year and the Report issued thereon by the External Auditors of SQM. Similarly, it also examined the Company’s Interim Consolidated Financial Statements for the 2017 business year.

| (b) | Examined at its meeting No. 118 on November 22, 2017, the execution of a bond issue agreement (“Agreement”) with BTG Pactual. BTG Pactual is a related party because SQM´s director Mr. Massú is a president of that entity. The Director´s Committee approved the Agreement. In its meeting No. 746 on November 22, 2017, the Board of Directors was duly informed of such approval and, in turn, also confirmed that the Agreement was on terms, prices and other conditions similar to those prevailing in the respective markets at the pertinent time and approved the execution of the Agreement, by the unanimous vote of directors present at the meeting with the abstention of Mr. Massú.

| (c) | Proposed to the Company’s Board of Directors the names of the External Auditors and the Independent Risk Rating Agencies for SQM and the Company’s Board of Directors, in turn, suggested their appointment to the respective Annual Ordinary Shareholders Meeting of SQM. The Company’s Board of Directors approved said suggestions and the Shareholders’ Meeting also ratified them.

| (d) | Examined and approved the remuneration system and the compensation plans for the Company’s employees and senior executives.

The Committee also (i) authorized the contracting by the Company of various consulting services with PwC, (ii) reviewed the expenses of the Company's CEO, and (iii) reviewed the reports from the Company’s internal audit and risk and compliance areas.

Finally, the Committee issued the Annual Management Report referred to in Law No. 18,046.

On April 28, 2017, the Annual General Shareholders’ Meeting of SQM approved an operational budget for the Committee; the operational budget is equivalent to the annual remuneration of the members of the Committee. The activities carried out by the Committee, as well as the expenses incurred by it, are disclosed at the General Shareholders Meeting. During 2017 the Committee incurred expenses of approximately US$167,000 related to the advisory services of Internal Audit and SOX Audit.

Article 50 bis of the Chilean Corporations Act states that the Committee should consist of three Directors, of which at least one member should preferably be independent from the controller (i.e., any person or entity who “controls” the company for Chilean law purposes), if any, and that their functions be remunerated.

6.D. Employees

As of December 31, 2017, we had 4,921 permanent employees, 216 of whom were employed outside of Chile. The average tenure of our permanent employees is approximately 6.3 years.

|  |  |  |  | As of December 31, |
|  | 2017 |  |  | 2016 |  |  | 2015 |
Employees in Chile |  |  | 4,630 |  |  |  | 4,535 |  |  |  | 4,048 |
Employees outside of Chile |  |  | 291 |  |  |  | 216 |  |  |  | 202 |
Total employees |  |  | 4,921 |  |  |  | 4,751 |  |  |  | 4,250 |

As of December 31, 2017, 64% of our permanent employees in Chile were represented by 22 labor unions, which represent their members in collective negotiations with us. Compensation for unionized personnel is established in accordance with the relevant collective bargaining agreements. The terms of most such agreements currently in effect are three years, and expiration dates of such agreements vary from agreement to agreement. Under these agreements, employees receive a salary according to a scale that depends upon job function and productivity. Unionized employees also receive certain benefits provided by law and certain benefits provided under the applicable collective bargaining agreement, which vary depending upon the terms of the collective agreement, such as scholarships and additional health, death and disability benefits, among others.

In addition, we own all of the equity of Institución de Salud Previsional Norte Grande Limitada (“Isapre Norte Grande”), which is a health care organization that provides medical services primarily to our employees, and of Sociedad Prestadora de Servicios de Salud Cruz de Norte S.A. (“Prestadora”), which is a hospital in María Elena. We make contributions to Isapre Norte Grande and to Prestadora in accordance with Chilean laws and the provisions of our various collective bargaining agreements, but we are not otherwise responsible for their liabilities.

| 102 |

Non-unionized employees receive individually negotiated salaries, benefits provided for by law and certain additional benefits which we provide.

We provide housing and other facilities and services for employees and their families at the María Elena site.

We do not maintain any pension or retirement programs for our Chilean employees. Most workers in Chile are subject to a national pension law, adopted in 1980, which establishes a system of independent pension plans that are administered by the corresponding Pension Fund Administrator (“Sociedad Administradora de Fondos de Pensiones”). We have no liability for the performance of any of these pension plans or any pension payments to be made to our employees. We do, however, sponsor staff severance indemnities plans for our employees and employees of our Chilean subsidiaries whereby we commit to provide a lump sum payment to each employee at the end of his/her employment, whether due to death, termination, or resignation.

Over 95% of our employees are employed in Chile, of which approximately 64% were represented by 22 labor unions as of December 31, 2017. As of July 31, 2017, we concluded renegotiations with three unions. As a result, all collective labor contracts were renegotiated for the duration of three years. In November 2017, we began a new cycle of individual collective labor contract negotiations. We are exposed to labor strikes and illegal work stoppages that could impact our production levels. If a strike or illegal work stoppage occurs and continues for a sustained period of time, we could be faced with increased costs and even disruption in our product flow that could have a material adverse effect on our business, financial condition and results of operations.

6.E. Share Ownership

We do not grant stock options or other arrangements involving the capital of SQM to directors, managers or employees. For more information on the shareholdings of current directors and executive officers, see “Item 6. Directors, Senior Management and Employees—Directors and Senior Management.”

SQM has been informed that, as of April 2, 2018, Mr. Julio Ponce Lerou, who is the brother of Eugenio Ponce L., and related persons control 100% of Inversiones SQYA Ltda. (“SQYA”) and 100% of Inversiones SQ Ltda. These two companies control indirectly 30.38% of all shares of SQM (consisting of 71,871,838 Series A shares and 8,074,874 Series B shares), as follows: (i) Inversiones SQ Ltda. controls 0.0258% of Norte Grande S.A. (“Norte Grande”) and SQYA controls 67.59% of Norte Grande, which controls 76.82% of Sociedad de Inversiones Oro Blanco S.A., which controls 88.64% of Pampa Calichera, which controls 20.13% of SQM; (ii) Pampa Calichera controls 99.99% of Inversiones Global Mining (Chile) Limitada, which controls 3.34% of SQM and (iii) Norte Grande controls 76.34% of Nitratos de Chile S.A., which controls 98.89% of Potasios de Chile S.A., which controls 10.07% of Pampa Calichera and 6.91% of SQM. Thus, Pampa Calichera and its related companies, Inversiones Global Mining Chile Limitada and Potasios de Chile S.A. (together, the “Pampa Group”), control 30.38% of SQM.

As of April 2, 2018, Kowa Company Ltd., Inversiones La Esperanza (Chile) Limitada, Kochi S.A., and Kowa Holdings America Inc. (together, the “Kowa Group”) are owners of 2.11% of all shares in SQM. On December 21, 2006, the Pampa Group and the Kowa Group entered into a Joint Operation Agreement which currently allows them to have the status of Controller Group of the Company.

The stake held by PCS as of December 31, 2017, 2016 and 2015 was 32.00% of SQM’s total shares.

In addition to the Joint Operation Agreement discussed above, on April 17, 2017, certain entities owned by the Pampa Group, the Kowa Group and PCS, which collectively own 64.49% of the total outstanding shares of SQM, entered into a letter agreement with respect to certain corporate governance matters of SQM (the “Corporate Governance Agreement”). A full copy of the Corporate Governance Agreement is attached hereto as Exhibit 99.4 and incorporated herein by reference.

On October 18, 2017, PCS issued a press release announcing the approval by the Competition Commission of India for the proposed merger between PCS and Agrium Inc. The approval was conditioned on PCS’ commitment to divest its minority shareholdings in several companies, including SQM, within 18 months. PCS and Agrium Inc. completed the merger on January 1, 2018, forming Nutrien. As of April 2, 2018, Nutrien has not yet completed the sale of any portion of its interest in SQM.

On December 18, 2017, in connection with the Corfo Arbitration Agreement, the companies that are part of the Pampa Group entered into an agreement for the benefit of Corfo (the “Pampa Group Agreement”), which, among other things, provides for: (i) the termination of the Joint Operation Agreement, and (ii) an agreement to not enter into any joint action with third parties that allows Pampa Group to acquire the status of sole controller or joint controller, as defined by article 97 of the Chilean Securities Market Law. The obligations set forth in clause (ii) expire on December 31, 2030. In addition, the Pampa Group Agreement also includes numerous provisions relating to corporate governance and control. The effectiveness of the obligations of the parties to the Pampa Group Agreement is subject to the execution of the amendments of the Lease Agreement and the Project Agreement and the obtainment of all approvals under Chilean Law. See “Item 3.D. Risk Factors” and “Item 8.A.7 Legal Proceedings.” Neither SQM nor any of its subsidiaries, including SQM Potasio S.A. and SQM Salar, is a party to the Pampa Group Agreement. A full copy of the Pampa Group Agreement is attached hereto as Exhibit 99.5 and incorporated herein by reference. Upon termination of the Joint Operation Agreement pursuant to the Pampa Group Agreement, the Pampa Group and the Kowa Group would cease to be a Controller Group.

The Company believes that approximately 51.31% of its Series A shares and 31.25% of its Series B shares were beneficially held in Chile as of April 2, 2018. Approximately 1,391 record holders were in Chile as of April 2, 2018.

Series A and Series B common shares have the same economic rights (i.e., both series are entitled to share equally in any dividends declared on the outstanding stock) and voting rights at any shareholders meeting, whether ordinary or extraordinary, with the exception of the election of the Board, in which the Series A shareholders elect seven members and the Series B shareholders elect one member.

Additionally, Series B common shares cannot exceed 50% of SQM’s issued, subscribed and paid shares; shareholders of at least 5% of this Series may call an Ordinary or Extraordinary Shareholders’ Meeting; and the director elected by this Series may request an extraordinary Board meeting without the authorization of the Chairman of the Board. These conditions will remain in effect until 2043. Under our By-laws, the maximum individual voting power personally and/or in representation of other shareholders per Series is limited to 37.5% of the subscribed shares of each Series with voting rights and 32% of the total subscribed shares with voting rights, with any excess being deducted from the number of shares such shareholder may vote. To calculate these percentages, shares that belong to the voting shareholder’s related persons must be added. In addition, the director elected by the Series B shareholders cannot vote in the election of the Chairman of the Board if a tie vote has occurred in the prior voting process. As of April 2, 2018, there were 142,819,552 Series A common shares and 120,376,972 Series B common shares outstanding.

On April 2, 2018, Sociedad de Inversiones Pampa Calichera S.A. and Potasios de Chile S.A., which collectively own shares of SQM representing more than 10% of the total voting rights of SQM, sent a letter to SQM requesting SQM to hold an extraordinary shareholders’ meeting to amend the By-laws of SQM. The letter proposes technical changes to the By-laws as well as an amendment providing for a new “second transitory article” as follows:

“FOR THE ENTIRE PERIOD BETWEEN APRIL 27, 2018 AND DECEMBER 31, 2030, THE RESTRICTION TO NOT VOTE MORE THAN 37.5% OF ANY SERIES OF COMPANY SHARES, AS ESTABLISHED BY THE THIRTY-FIRST ARTICLE OF THE BYLAWS, RECOGNIZES THE FOLLOWING EXCEPTION: If two or more people, related to each other or not, with or without an joint action agreement, acquire between now and December 31, 2030 (the “entering shareholders”), a quantity of the company’s A-series shares which allows them to exercise effective voting rights for more than 37.5% of the series, then any shareholder or group of shareholders listed in the respective registry as of this date, that owns a number of the company’s A-series shares corresponding to more than 37.5% of said series, shall have the right to vote a number of the company’s A-series shares in its power equivalent to the lesser of (i) the number of those series’ shares owned by the existing shareholders at the present date, and (ii) the number of those series’ shares for which the entering shareholders could exercise voting rights. Likewise, if, for any reason, one of the company’s shareholders listed in the respective registry to date and owner of a number of the company’s A-series shares corresponding to more than 37.5% of said series, were to acquire, between the present date and December 31, 2030, the capacity to exercise effective voting rights for more than 37.5% of the company’s A-series shares, whether as a result of a joint action agreement with other shareholders, including existing shareholders, or by any other means, then any other company shareholder or group of shareholders not related to them that owns a number of the company’s A-series shares corresponding to more than 37.5% of said series, including both existing and entering shareholders, shall have the right to vote a number of shares of said series in its power equivalent to the lesser of (i) the number of those series’ shares owned by the latter shareholder or shareholders, and (ii) the number of those series’ shares for which the existing shareholder has the capacity to exercise voting rights in excess of the 37.5% restriction.”

7.B. Related Party Transactions

Title XVI of the Chilean Corporations Act regulates transactions with related parties for publicly held corporations and its related parties.

Articles 146 to 149 of the Chilean Corporations Act requires that our transactions with related parties (i) have as their purpose to contribute to SQM’s interests (ii) be on price, terms and conditions similar to those customarily prevailing in the market at the time of their approval and (iii) satisfy the requirements and procedures established by the Chilean Corporations Act. Violation of such articles may also result in administrative or criminal sanctions and civil liability may be sought by SQM, shareholders or interested third parties that suffer losses as a result of such violations.

In addition, article 89 of the Chilean Corporations Act requires that transactions between affiliates, subsidiaries or related parties of a closed-stock company, such as some of SQM’s main affiliates and subsidiaries, shall also be on terms similar to those customarily prevailing in the market. Directors and executive officers of companies that violate article 89 are liable for losses resulting from such violations.

With respect to SQM, operations with related parties include negotiations, proceedings, contracts or operations involving SQM and its controller, directors, managers and officers, and their spouses and relatives, and other companies and persons connected to the abovementioned parties or mentioned in the By-laws or by the Directors’ Committee. Such operations may only be carried out if (i) their objective is to contribute to SQM’s interests and if their price, terms and conditions conform to prevailing market prices, terms and conditions at the time of their approval and (ii) they satisfy the requirements and procedures established by the Chilean Corporations Act. Such requirements include, among others:

| 106 |

| · | that the operation be informed to the Directors’ Committee and to the Board of Directors prior to its execution;

| · | that the Board of Directors, excluding any Directors involved in the operation, approves the operation with an absolute majority of its members, or, if an absolute majority is not feasible, with a unanimous vote by the Directors not involved in the transaction, or, if neither of these options is available, that an Extraordinary Shareholders’ Meeting be held and that shareholders representing 2/3 of the outstanding shares with voting rights approve the operation. In the latter case, prior to the meeting, the shareholders must be provided with a report by an independent evaluator and with statements by the directors as to whether or not such operation is in SQM’s interest;

| · | that the grounds for the decision and for the exclusion be recorded in the respective minutes of the Board meeting; and

| · | that the agreement and the names of the directors who approved the same be reported at the next shareholders’ meeting. Infractions will not affect the validity of the operation but they will grant SQM or its shareholders the right to demand that the related party committing such infraction refund the amount equivalent to the benefits received by such party in the operation to SQM, and that such party indemnify for any corresponding damages.

However, the Board of Directors may authorize the following operations with related parties to be carried out without following such requirements and procedures, as long as such authorization is obtained in advance: (a) operations wherein the amount of the transaction is not significant or (b) operations that, according to the general policies on customary practices determined by the Board of Directors, are considered normal based on SQM’s business activities or (c) operations carried out between legal entities wherein SQM holds at least a 95% ownership interest in the counterpart.

Accounts receivable from and payable to related companies are stated in U.S. dollars and accrue no interest. Other than the above, transactions are made under terms and conditions that are similar to those offered to unrelated third parties. We further believe that we could obtain from third parties all raw materials now being provided by related parties that are not our affiliates. The provision of such raw materials by new suppliers could initially entail additional expenses.

In each case, terms and conditions vary depending on the transaction pursuant to which it was generated.

The Company regularly enters into business arrangements with related parties, principally its joint ventures and associates, which are described in Note 9 to our Consolidated Financial Statements.

8.A.7 Legal Proceedings

Chilean Investigation

The SII has conducted investigations related to the payment of invoices by SQM and its subsidiaries, SQM Salar and SQM Industrial S.A., for services that may not have been properly supported or that may not have been necessary to generate corporate income. The Chilean Public Prosecutor also has conducted related inquiries to determine whether such payments may be linked with alleged violations by SQM, these subsidiaries and public officials of political contribution or anti-corruption laws.

On February 26, 2015, SQM’s Board of Directors resolved to establish an ad-hoc Committee authorized to conduct an internal investigation relating to the issues that were the subject of the SII and the Chilean Public Prosecutor investigations and to retain such independent external advice as it deemed appropriate. The original members of the ad-hoc Committee were José María Eyzaguirre B., Juan Antonio Guzmán M. and Wolf von Appen B.

The ad-hoc Committee engaged its own lawyers from Chile and the U.S. and forensic accountants from the U.S. to assist with its internal review. The U.S. lawyers retained by the ad-hoc Committee were principally charged with reviewing the relevant facts and analyzing those facts against the requirements of the FCPA. The factual findings of the ad-hoc Committee, however, were ultimately shared with Chilean as well as U.S. authorities.

On March 12, 2015, José María Eyzaguirre B. resigned from the ad-hoc Committee and his position was subsequently filled by Hernán Büchi B.

On March 16, 2015, the Board of Directors decided to terminate the employment contract of the Company’s then- CEO, Patricio Contesse G. This followed his failure to cooperate with the ad-hoc Committee’s investigation.

On March 17, 2015, three members of the Board of Directors resigned, all of whom had been nominated by PCS, one of SQM’s two principal shareholder groups. PCS issued a press release stating that the directors resigned because of their concern that they could not ensure that the Company was conducting an appropriate investigation and collaborating effectively with the Chilean Public Prosecutor.

| 108 |

On March 20, 2015, the Company identified to the SII approximately US$11 million in payments of invoices that may not have been properly supported by services rendered or that may not qualify as tax expenses under the Chilean tax code. These payments originated from the office of the former CEO, Patricio Contesse G., during the six-year tax period from 2009 to 2014. As a result, the Company subsequently submitted amendments to its tax returns for the 2009 to 2014 tax years and thereafter paid taxes and interest relating to such amended returns totaling approximately US$7 million. On April 24, 2015, the Company announced that it had identified up to an additional US$2 million in payments by its subsidiary SQM Salar S.A. during the same six-year tax period that were also authorized by the former CEO and that may be deemed not properly supported by services rendered or that may not qualify as tax expenses under the Chilean tax code. Subsequently, SQM Salar S.A. filed amended tax returns and paid taxes and interest relating to such amended returns totaling approximately US$1.2 million. On August 14, 2015, the Company announced that it had identified to the SII approximately US$1.6 million in additional payments by SQM S.A. and its subsidiary SQM Industrial S.A. that may be deemed not properly supported by services rendered or that may not qualify as tax expenses under the Chilean tax code. SQM S.A. and SQM Industrial S.A. subsequently filed amended tax returns and, in early 2016, SQM Industrial S.A. paid taxes and interest relating to such amended returns totaling approximately US$0.3 million, and SQM S.A. paid taxes and interest relating to such amended returns totaling approximately US$1.3 million. The statute of limitations under Chilean law for tax claims is up to six years, during which period the former CEO had an annual discretionary budget covering the Company and its subsidiaries of approximately US$6 million.

On March 23, 2015, the SII, based on the Income Tax Law (Ley de Impuesto a La Renta) filed a criminal claim against the Company’s former CEO and the current CEO and CFO in their capacities as the Company’s tax representatives relating to part of the payments referred to above. This and subsequent related similar claims filed by the SII against these officers and third parties are currently under review by the Chilean Public Prosecutor.

On March 31, 2015, the CMF filed an administrative claim against five current or former members of the Board of Directors, alleging that they did not release information in a timely manner relating to the payments that are subject to the tax claim referred to above. On September 30, 2015, the CMF proceeded to fine the three current and the two former members of the Board of Directors UF1,000 each (approximately US$36,000). They are currently appealing this decision to the Chilean courts.

On April 24, 2015, new members were elected to the Board of Directors at the Annual General Shareholders’ Meeting, including three new members that were nominated by PCS, and the ad-hoc Committee was subsequently reconstituted by Board of Directors members Robert A. Kirkpatrick, Wolf von Appen B. and Edward J. Waitzer.

On April 30, 2015, the Chilean Public Prosecutor, after reviewing the claims filed by the SII, informed the Company’s former CEO that it was formally investigating allegations that he approved the payment of invoices that may not be properly supported by services rendered or that may not qualify as tax expenses under the Chilean tax code and in connection therewith made intentionally false or incomplete declarations or used fraudulent procedures designed to conceal or disguise the true amount of transactions or to circumvent taxes. If he is finally adjudicated responsible, the Company may also be subject to the payment of a fine by the Chilean Criminal Court totaling 50% to 300% of the taxes paid. The Company estimates that no provision is needed at this stage.

| 109 |

On May 11, 2015, the SII filed an additional criminal claim against the former CEO and the current CEO and CFO in their capacities as the Company’s tax representatives alleging violations of the Chilean Inheritance and Donations Law (Ley sobre Impuesto a Las Herencias, Asignaciones y Donaciones). The claim states that the Company paid two invoices in 2009 and 2010 totaling approximately US$175,000 that are alleged to have been improperly supported. The claim states that these payments should have been classified as donations, and appropriate taxes should have been paid. These payments were accounted for in the amended tax returns filed with the SII. Subsequently, the SII filed a number of additional claims against these officers and third parties alleging violations of Chilean tax law and the Chilean Inheritance and Donations Law. The most recent of these criminal claims was filed by the SII on March 9, 2016. All of these claims are under review by the Chilean Public Prosecutor.

On September 29, 2015, the Company was notified of a labor lawsuit by its former CEO, Patricio Contesse, claiming payment from the Company related to the termination of his employment contract. The total amount claimed in the lawsuit is approximately Ch$4.0 billion (approximately US$5.7 million), including severance payments for years of service and other legal or contractual payments. The Company has not paid any indemnities to the former CEO, and the lawsuit is pending in the Chilean courts. The Company estimates that no provision is needed at this stage. On March 27, 2017, the Company reached an agreement with Mr. Contesse to terminate the labor lawsuit Mr. Contesse filed against the Company. The amount included in the agreement was provisioned for in the financial statements as of December 31, 2016.

During 2015, the ad-hoc Committee that was established in February 2015, conducted an investigation into whether the Company faced possible liability under the FCPA. The ad-hoc Committee engaged its own separate counsel, Shearman & Sterling LLP, which presented a report to the Board of Directors on December 15, 2015.

Following the presentation by the ad-hoc Committee of its findings to the Board of Directors, the Company voluntarily shared the findings of the ad-hoc Committee investigation with authorities in Chile and the U.S. (including the SEC and the DOJ).

On January 13, 2017, the Company and the DOJ reached agreement on the terms of a DPA that would resolve the DOJ’s inquiry, based on alleged violations of the books and records and internal controls provisions of the Foreign Corrupt Practices Act. Among other terms, the DPA calls for the Company to pay a monetary penalty of US$15,487,500, and engage a compliance monitor for a term of two (2) years. Upon successful completion of the three (3) year term of the DPA, all charges against the Company would be dismissed. On the same date, the SEC agreed to resolve its inquiry through an administrative cease and desist order, arising out of the alleged violations of the same accounting provisions of the FCPA. Among other terms, the SEC order calls for the Company to pay an additional monetary penalty of US$15 million. These penalties were reflected in the 2016 financial statements.

On January 26, 2018, the 8th Court of Santiago approved a deferred prosecution agreement proposed by the Chilean Public Prosecutor, relating to SQM and its subsidiaries SQM Salar and SQM Nitratos S.A., to suspend an investigation against these entities related to possible corruption issues and responsibility for the lack of supervision and management. Under the deferred prosecution agreement, SQM, SQM Salar and SQM Nitratos S.A., have not admitted responsibility in the matter subject to the investigation but agreed to pay an aggregate amount of (i) Ch$900,000,000 to the Chilean government, and (ii) Ch$1,650,000,000 to various charitable organizations. As of January 26, 2018, these amounts were equivalent to approximately US$1.5 million and US$2.8 million, respectively, and were accrued in the Consolidated Financial Statements of the Company for 2017. In addition, the companies have agreed to provide the Chilean Public Prosecutor with a report on the enhancements to their compliance program, implemented in recent years, with special emphasis on the incorporation of best practices in various jurisdictions.

| 110 |

In the event that the applicable regulatory authorities believe that the terms of the DPA or the deferred prosecution agreement with the Chilean Public Prosecutor are not complied with, it is possible that such regulatory authorities may reinstate the suspended proceedings against us and may bring further action against us, including in the form of additional inquiries or legal proceedings. Responding to our regulators’ inquiries and any future civil, criminal or regulatory inquiries or proceedings diverts our management’s attention from day-to-day operations. Additionally, expenses that may arise from responding to such inquiries or proceedings, our review of responsive materials, any related litigation or other associated activities may continue to be significant. Current and former employees, officers and directors may seek indemnification, advancement or reimbursement of expenses from us, including attorneys’ fees, with respect to the current inquiry or future proceedings related to this matter.

Class Actions

Since October 2015, a consolidated class action lawsuit has been pending against the Company in the United States District Court for the Southern District of New York, alleging violations of the U.S. securities laws in connection with the subject matter of the investigations described above. The complaint alleges that certain statements made by the Company, principally in the Company’s SEC filings and press releases, were materially false and/or misleading in violation of Section 10(b) of the Securities Exchange Act of 1934 (the “Exchange Act”) and Rule 10b-5 promulgated thereunder. Specifically, the complaint challenges certain of the Company’s statements concerning its compliance with applicable laws and regulations; the effectiveness of its internal controls; its adoption of a code of ethics consistent with SEC requirements; its revenues and taxes owed; and its compliance with applicable accounting standards. The complaint also alleges that the Company made inadequate disclosures concerning the status of the Corfo litigation described below. The lead plaintiff seeks damages of an undetermined amount to recover the economic losses allegedly suffered by the class as a result of the challenged statements.

On March 30, 2016, the Company filed a motion to dismiss the complaint under the doctrine of forum non conveniens or, alternatively, pursuant to Rules 9(b) and 12(b)(6) of the Federal Rules of Civil Procedure for failure to state a claim under Section 10(b) of the Exchange Act. Briefing on that motion to dismiss was completed on June 29, 2016. On March 28, 2017, the district court issued an opinion and order denying in part and granting in part the motion to dismiss. The district court denied the motion to dismiss under the doctrine of forum non conveniens; denied the motion to dismiss for failure to state a claim with respect to the statements concerning legal compliance, internal controls, and financial reporting and accounting; and granted the motion to dismiss for failure to state a claim with respect to the statements concerning the Company’s code of ethics and the status of the Corfo litigation.

On January 10, 2018, the lead plaintiff filed a motion to certify a class consisting of all persons who purchased SQM ADSs between June 30, 2010 and March 18, 2015, and such motion remains pending before the court.

Corfo Litigation

Our subsidiary SQM Salar holds exclusive and temporary exploitation rights to mineral resources in 81,920 hectares in the Salar de Atacama pursuant to (i) the Lease Agreement, and (ii) the Project Agreement. The mining exploitation concessions related to such rights are owned by Corfo and leased to SQM Salar in exchange for quarterly lease payments to Corfo based on specified percentages associated to the value of the products resulting from the minerals extracted from such concessions. For the year ended December 31, 2017, revenues related to products originating from the Salar de Atacama represented 47% of our consolidated revenues, consisting of revenues from our potassium business line and our lithium and derivatives business line for the period. All of our products originating from the Salar de Atacama are derived from our extraction operations under the Lease Agreement. As of December 31, 2017, only 13 years remain on the term of the Lease Agreement and we had extracted approximately 64% of the total permitted accumulated extraction and sales limit of lithium.

| 111 |

In May 2014, Corfo initiated an arbitration proceeding against SQM Salar alleging (i) SQM Salar had incorrectly applied the formulas to determine lease payments resulting in an underpayment to Corfo of at least US$8.9 million for 2009 through 2013 and (ii) SQM Salar had not complied with its obligation to protect the mining rights of Corfo by failing to construct or replace markers to delineate property lines. Based on the alleged breaches of the Lease Agreement, Corfo sought (i) at least US$8.9 million plus any other amount that may be due in respect of periods after 2013, (ii) early termination of the Lease Agreement, (iii) lease payments that would have been paid through 2030 as compensation for the early termination of the Lease Agreement and (iv) punitive damages (daño moral) equal to 30% of the contractual damages awarded. SQM Salar contested the claim, asserting that both parties have applied mutually agreed formulas for the calculation and payment of lease payments for more than 20 years without conflict, in accordance with the terms of the Lease Agreement and their mutual understanding of the agreements by the parties during the term of the Lease Agreement. SQM Salar also asserted that the alleged breaches would be technical breaches and that Corfo may terminate the Lease Agreement solely for a material breach.

In August 2016, Corfo requested a second arbitration proceeding, demanding (i) the early termination of the Project Agreement signed between Corfo, SQM Potasio S.A., SQM Salar, and the Company, (ii) the dissolution of SQM Salar and (iii) the early termination of the Lease Agreement for alleged breaches of the Project Agreement. In addition, Corfo demanded SQM Salar return (i) the assets Corfo contributed to it under a condition subsequent, (ii) the OMA mining properties and the aquifers included in the Lease Agreement, (iii) the water rights granted to SQM Salar and (iv) the legal mining easements identified in the lawsuit. Finally, Corfo requested that the defendants pay damages as a result of the breaches alleged in the lawsuit.

On January 17, 2018, Corfo, SQM Salar and SQM Potasio S.A. entered into the Corfo Arbitration Agreement to (i) terminate the arbitration proceedings and (ii) amend the Lease Agreement and the Project Agreement. The agreement to amend the Lease Agreement for the Salar de Atacama concession and the Project Agreement seeks to reflect, among other terms, the following: (i) an increase in lease payments by increasing the lease rates associated with the sale of the different products produced in the Salar de Atacama; (ii) a commitment by SQM Salar to contribute (a) between US$10.8 and US$18.9 million per year to research and development efforts, (b) between US$10 to US$15 million per year to the communities in close proximity to the Salar de Atacama, and (c) 1.7% of total annual sales of SQM Salar to regional development; (iii) the authorization by Corfo to increase the production and sales of lithium products produced in the Salar de Atacama up to 349,553 metric tons of lithium metallic equivalent (1,860,670 tons of lithium carbonate equivalent), which is in addition to the approximately 64,816 metric tons of lithium metallic equivalent (345,015 tons of lithium carbonate equivalent) remaining from the originally authorized amount; (iv) an obligation of SQM Salar to offer part of its lithium production (up to a maximum of 25%) at a preferential price to value-added producers that will potentially develop in Chile; (v) an obligation of SQM Salar to strengthen its corporate governance by incorporating various audit, environmental control and coordination mechanisms with Corfo, which shall be set forth in amendments to the By-laws of SQM Salar, including among others: (a) incorporating specific rules for the management of the company, including that two of the directors of SQM Salar are independent and meet the requirements established for independent directors of a public company and (b) requiring the Board of Directors of SQM Salar to designate a committee to monitor compliance with the Lease Agreement and the Project Agreement and to establish the regulations that will govern this committee and its functions; (vi) extensive regulation regarding the return of assets upon termination of the contracts and granting purchase options; and (vii) prohibitions against the sale of lithium brine extracted from leased mining concessions by the Company, SQM Salar and SQM Potasio S.A. For further information on the terms of the Corfo Arbitration Agreement, see Note 32.2 to our Consolidated Financial Statements. These amendments were subject to the issuance of the applicable resolutions of the Office of the Comptroller General of the Republic (Contraloría General de la República) and the CCHEN.

On February 15, 2018 and February 16, 2018, the Atacamenos Indigenous Organization (Consejo de Pueblos Atacamenos) initiated legal actions challenging the amendments of the Lease Agreement and the Project Agreement. The legal actions are pending before the Santiago Court of Appeals.

| 112 |

On March 8, 2018, the CCHEN published its authorization for the increase in the quota of the amount of lithium that may be extracted from the Salar de Atacama concession for all periods for which there are increases under the proposed Lease Agreement amendment with Corfo. In addition, the authorization by the CCHEN provides that the amendments to the Lease Agreement and the Project Agreement may be revoked if any person or entity acquires control or a significant influence (influencia decisiva) over SQM without prior antitrust approval. SQM has challenged the CCHEN authorization with the objective of eliminating such provision. SQM believes that its challenge will not affect the validity of the Corfo Arbitration Agreement or the amendments to the Lease Agreement or the Project Agreement. However, there can be no assurance that SQM will prevail in eliminating such provision and in the event such provision is not eliminated, there could be no assurance that the amendments to the Lease Agreement and the Project Agreement will not be revoked upon violation of such provisions. In addition, the adoption of the CCHEN authorization is currently being challenged by the Atacamenos Indigenous Organization (Consejo de Pueblos Atacamenos), which challenge, if successful, may result in the revocation of CCHEN authorization.

On April 10, 2018, the Office of the Comptroller General of the Republic (Contraloría General de la República) issued a resolution approving the amendments of the Lease Agreement and the Project Agreement.

In addition, in connection with the Corfo Arbitration Agreement, on December 18, 2017, the companies that are part of the Pampa Group entered into Pampa Group Agreement for the benefit of Corfo, which, among other things, provides for: (i) the termination of the Joint Operation Agreement, and (ii) an agreement to not enter into any joint action with third parties that allows Pampa Group to acquire the status of sole controller or joint controller, as defined by article 97 of the Chilean Securities Market Law. The obligations set forth in clause (ii) expire on December 31, 2030. In addition, the Pampa Group Agreement also includes numerous provisions relating to corporate governance and control. The effectiveness of the obligations of the parties to the Pampa Group Agreement is subject to the effectiveness of the amendments of the Lease Agreement and the Project Agreement. Neither SQM nor any of its subsidiaries, including SQM Potasio S.A. and SQM Salar, is a party to the Pampa Group Agreement.

SQMNA Litigation

In October 2010, the City of Pomona, California, named Sociedad Química y Minera de Chile S.A. and SQM North America Corporation (“SQMNA”) and SQM as defendants in an action filed in the California Superior Court for Los Angeles County. In this matter the plaintiff seeks damages for alleged groundwater contamination from the use of defendant’s fertilizer products. The Plaintiff subsequently withdrew its lawsuit against SQM. On June 10, 2015, the jury rejected the lawsuit against SQMNA, and the plaintiff filed an appeal which was granted by the Ninth Circuit Court of Appeals. The matter has been remanded to the District court for a complete re-trial.

In October 2010, the City of Lindsay, California, named Sociedad Química y Minera de Chile S.A. and SQMNA as defendants in an action filed in the California Superior Court for Tulare County. In this matter the plaintiff seeks damages for alleged groundwater contamination from the use of defendant’s fertilizer products. This case is pending in the trial court. SQMNA and SQM (if it is legally served) intend to vigorously defend this action. The process has been suspended and we are awaiting results from the case in Pomona. SQMNA and SQM intend to vigorously defend this action.

Other Matters

In addition, various lawsuits, claims and proceedings, other than those specifically disclosed above, have been or may be instituted or asserted against the Company, relating to the conduct of the company’s business, including those pertaining to mining, civil, tort, commercial, labor and regulatory matters, among others. Although the outcome of other litigation cannot be predicted with certainty, and some lawsuits, claims or proceedings may be disposed of unfavorably to the Company, our management believes the disposition of such other pending matters will not have a material effect on the company’s business, financial condition, results of operations or cash flows.

8.A.8. Dividend Policy

As required by Chilean law and regulations, our dividend policy is decided upon from time to time by our Board of Directors and is announced at the Annual Ordinary Shareholders’ Meeting, which is generally held in April of each year. Shareholder approval of the dividend policy is not required. However, each year the Board must submit the declaration of the final dividend or dividends in respect of the preceding year, consistent with the then-established dividend policy, to the Annual Ordinary Shareholders’ Meeting for approval. As required by the Chilean Companies Act, unless otherwise decided by unanimous vote of the holders of issued shares, we must distribute a cash dividend in an amount equal to at least 30% of our consolidated net income for that year (determined in accordance with CMF regulations), unless and to the extent the Company has a deficit in retained earnings.

On April 11, 2017, the Board of Directors, agreed to recommend to the shareholders the payment of a definitive dividend representing 100% of the 2016 net income. This definitive dividend payment was presented for consideration at the Annual General Shareholders’ Meeting held on April 28, 2017. The amount of the final dividend approved by shareholders at the Annual General Shareholders’ Meeting held on April 28, 2017 was US$1.05735 per share; the amount of US$0.85487 per share had to be deducted from the final dividend as it had been already paid as a provisional dividend on December 20, 2016. The balance, in the amount of US$0.20248 per share, was paid and distributed to Company’s shareholders on May 11, 2017.

Our 2017 dividend policy, as disclosed at our 2017 Annual General Shareholders’ Meeting held on April 28, 2017, was to pay a percentage of our net income that is determined as per following financial parameters:

(i) 100% of the 2017 net income, when the following financial parameters are met: (a) the total sum of cash and cash equivalent, and other current financial assets (“Cash”) divided by the total sum of the current financial liabilities (“Current Financial Liabilities”) is equal to or greater than 2.5 times, and (b) the total sum of the current liabilities and the non-current liabilities (“Total Liabilities”) divided by the total sum of the equity (“Equity”) is equal to or less than 1.1 times.

(ii) 80% of the 2017 net income when the following financial parameters are met: (a) Cash divided by Current Financial Liabilities is equal to or greater than 2.0 times, and (b) the total sum of the Total Liabilities divided by the total Equity is equal to or less than 1.2 times.

(iii) 60% of the 2017 net income when the following financial parameters are met: (a) Cash divided by Current Financial Liabilities is equal to or greater than 1.5 times, and (b) Total Liabilities divided by Equity is equal to or less than 1.3 times.

If none of the foregoing financial parameters are met, the Company shall distribute and pay, as a final dividend, and in favor of the respective shareholders, 50% of the 2017 net income.

On May 17, 2017, the Board of Directors agreed to pay and distribute on June 15, 2017 a provisional dividend of US$103 million, equivalent to US$0.39222 per share, to be charged against the 2017 net income.

On August 23, 2017, the Board of Directors agreed to pay and distribute on September 14, 2017 a provisional dividend of US$101 million, equivalent to US$0.38432 per share, to be charged against the 2017 net income.

On November 22, 2017, the Board of Directors agreed to pay and distribute on December14, 2017 a provisional dividend of US$113 million, equivalent to US$0.42879 per share, to be charged against the 2017 net income.

On March 28, 2018, the Board of Directors agreed to recommend to the shareholders the payment of a definitive dividend representing 100% of the 2017 net income and a special dividend (dividendo eventual) in the amount of US$100 million. The payment of these dividends will be presented for consideration at the Annual General Shareholders’ Meeting held on April 27, 2018. Therefore, and subject to the approval at the shareholders’ meeting, the Company shall pay a final dividend of US$1,62501 per share to be charged against the 2017 net income and a special dividend of US$0.37994 per share to be charged against the retained earnings. The amount of US$1.20533 per share must be deducted from the final dividend, as it was already paid in the form of interim dividends. The balance, in the amount of US$0.41968 per share, and a special dividend of US$0.37994 per share shall be paid and distributed to Company´s shareholders, pending shareholders´ approval, on May 10, 2018.

The dividend policy for 2018 is expected to be announced at the Annual Shareholders’ Meeting held on April 27, 2018.

We generally declare dividends in U.S. dollars (but may declare dividends in Chilean pesos) and pay such dividends in Chilean pesos. When a dividend is declared in U.S. dollars, the exchange rate to be used to convert the dividend into Chilean pesos is decided by the shareholders at the meeting that approves the dividend, which has usually been the Observed Exchange Rate on the date the dividend is declared. In the case of interim dividends, the exchange rate to be used is the Observed Exchange Rate published five business days before the payment date.

The amount and timing for payment of dividends is subject to revision from time to time, depending upon our then current level of sales, costs, cash flow and capital requirements, as well as market conditions. Accordingly, there can be no assurance as to the amount or timing of declaration or payment of dividends in the future. Any change in dividend policy would ordinarily be effective for dividends declared in the year following adoption of the change, and a notice as to any such change of policy must be filed with Chilean regulatory authorities and would be publicly available information.

Dividends

Each Series A common share and Series B common share is entitled to share equally in any dividends declared on the outstanding capital stock of SQM.

The following table shows the U.S. dollar equivalent of dividends per share and per ADS paid in each of the years indicated, based on the Observed Exchange Rate for the date on which the dividend was declared.

Dividends payable to holders of ADSs will be paid net of conversion expenses of the Depositary and will be subject to Chilean withholding tax, currently imposed at the rate of 35% (subject to credits in certain cases).

As a general requirement, a shareholder who is not a resident of Chile must register as a foreign investor under one of the foreign investment regimes contemplated by Chilean law to have dividends, sale proceeds or other amounts with respect to its shares remitted outside Chile through the Formal Exchange Market. Under the Foreign Investment Contract, the Depositary, on behalf of ADR holders, will be granted access to the Formal Exchange Market to convert cash dividends from Chilean Pesos to U.S. dollars and to pay such U.S. dollars to ADS holders outside Chile net of taxes, and no separate registration of ADS holders is required.

Directors

As stated in article 9 of the Company’s By-laws, the Company has eight Directors. One of the directors must be “independent” as such term is defined in article 50 bis of Law No. 18,046. Moreover, the possession of shares is not a condition necessary to become a director of the Company.

As stated in article 10 of the Company’s By-laws, the term of the directors is of three years and they can be reelected indefinitely; thus, there is no age limit for their retirement.

The Company’s By-laws, in articles 16 and 16 bis, essentially establish that the transactions in which a director has a material interest must comply with the provisions set forth in articles 136 and 146 to 149 of Law No. 18,046 and the applicable regulations of such Law.

The Board of Directors duties are remunerated, as stated in article 17 of the Company’s By-laws, and the amount of that compensation is fixed yearly by the Ordinary Shareholders’ Meeting. Therefore, directors can neither determine nor modify their compensation.

Directors cannot authorize Company loans on their behalf.

The Board of Directors must provide shareholders and the public with sufficient, reliable and timely information pertaining to the Company’s legal, economic and financial situation, as required by the Law or the CMF. The Board of Directors must adopt the appropriate measures in order to avoid the disclosure of such information to persons other than those persons who should possess such information as a result of their title, position or activity within the Company before such information is disclosed to shareholders and the public. The Board of Directors must treat business dealings and other information about the Company as confidential until such information is officially disclosed. No Director may take advantage of the knowledge about commercial opportunities that he has obtained through his position as Director.

Independent Directors and Directors Committee

According to Chilean Law, SQM must appoint at least one Independent Director and a Directors’ Committee, due to the fact that (a) the Company has a market capitalization greater than or equal to UF 1,500,000 and (b) at least 12.5% of the Company’s shares with voting rights are held by shareholders who, on an individual basis, control or possess less than 10% of such shares.

Persons who have not been involved in any of the circumstances described in the Law at any time during the preceding 18 months are considered independent. Candidates for the position of Independent Director must be proposed by shareholders representing 1% or more of the Company’s shares, at least 10 days prior to the date of the shareholders’ meeting that has been called in order to elect the Directors. No less than two days prior to the respective shareholders’ meeting, the candidate must provide the Chief Executive Officer with a sworn statement indicating that he: (a) accepts his candidacy for the position of Independent Director (b) does not meet any of the conditions that would prevent him from being the Independent Director (c) is not related to the Company, the other companies of the group to which the Company belongs, the controller of the Company, or any of the Company’s officers in such a way that would deprive a sensible person of a reasonable degree of autonomy, interfere with his ability to perform his duties objectively and effectively, generate a potential conflict of interest, or interfere with his independent judgment, and (d) assumes the commitment to remain independent as long as he holds the position of Director.

| 120 |

The Directors’ Committee shall have the following powers and duties: (a) to examine the reports of the external auditors, the balance sheet and other financial statements presented by the Company’s managers or liquidators to its shareholders and issue an opinion about the same prior to their submission for the approval of the shareholders (b) to propose to the Board of Directors the external auditors and risk rating agencies to be proposed to the shareholders at the respective shareholders’ meeting. In the event that an agreement cannot be reached, the Board of Directors shall formulate its own suggestion, and both options shall be submitted for shareholder consideration at such shareholders’ meeting (c) to examine the information relating to operations referred to in articles 146 to 149 of Law No. 18,046 and to prepare a report about such operations. A copy of such report shall be sent to the Board of Directors, and such report must be read at the Board Meeting called for the purpose of approving or rejecting the respective operation or operations (d) to examine the remuneration system and compensation plans for the Company’s management, officers and employees (e) to prepare an annual report on its activities, including its main recommendations to the shareholders (f) to inform the Board of Directors about whether or not it is advisable to hire the external audit firm to provide non-audit services where the audit firm is not prohibited from providing such services because the nature of the same could pose a threat to the audit firm’s independence, and (g) any other issues indicated in the Company’s By-laws or authorized by a shareholders’ meeting or the Board of Directors.

The Directors’ Committee shall be comprised of three members, with at least one independent member. In the event that more than three Directors have the right to form part of the Committee, these same Directors shall unanimously determine who shall make up the Committee. In the event that an agreement cannot be reached, the Directors who were elected with a greater percentage of votes by shareholders controlling or possessing less than 10% of the Company’s shares shall be given priority. If there is only one Independent Director, this Director shall name the other members of the Committee among the other Directors who are not independent. Such other members of the Committee shall have all of the rights associated with such position. The members of the Committee shall be compensated for their role. The amount of their remuneration shall be set annually at the General Shareholders’ Meeting, and it may not be less than the remuneration set for the Company Directors, plus an additional 1/3 of that amount. The General Shareholders’ Meeting shall determine a budget for the expenses of the Committee and its advisors. Such budget may not be less than the sum of the annual remunerations of the Committee members. The Committee may need to hire professional advisory services in order to carry out its duties in accordance with the abovementioned budget. The proposals made by the Committee to the Board of Directors that are not accepted by the latter must be reported to the shareholders’ meeting prior to the vote by shareholders on the corresponding matter or matters. In addition to the responsibilities that are associated with the position of Director, the members of the Committee are jointly and severally liable for any damages they cause in performing their duties as such to the shareholders and to the Company.

Shares

Dividends are annually distributed to the Series A and Series B shareholders of record on the fifth business day prior to the date for payment of the dividends. The By-laws do not specify a time limit after which dividend entitlement elapses but Chilean regulations establish that after five years, unclaimed dividends are to be donated to the fire department.

Article 5 of the Company’s By-laws establishes that Series B shares may in no case exceed 50% of SQM’s issued, outstanding and paid stock. SQM Series B shares have a restricted right to vote as they can only elect one director of the Company, regardless of their capital stock’s share. Series B shares have the right to call for an Ordinary or Extraordinary Shareholders’ Meeting when the shareholders of at least 5% of the Series B issued shares request so and for an Extraordinary Board of Directors Meeting without the Chairman’s authorization when it is requested by the director elected by the shareholders of the Series B shares. Series A shares have the option to exclude the director elected by Series B shareholders from the voting process in which the Chairman of the Board is to be elected, if there is a tie in the first voting process. However, articles 31 and 31 bis of the Company’s By-laws establish that in General Shareholders’ Meetings each shareholder will have a right to one vote for each share he owns or represents and (a) that no shareholder will have the right to vote for himself or on behalf of other shareholders of the same Series A or Series B shares representing more than 37.5% of the total outstanding shares with right to vote of each Series and (b) that no shareholder will have the right to vote for himself or on behalf of other shareholders representing more than 32% of the total outstanding shares with a right to vote, with any excess being deducted from the number of shares such shareholder may vote. In calculating a single shareholder’s ownership of Series A or B shares, the shareholder’s stock and those pertaining to third parties related to them are to be added.

| 121 |

Article 5 bis of the Company’s By-laws establishes that no person may directly or by means of related third persons concentrate more than 32% of the Company’s total shares with right to vote.

Each Series A share and Series B share is entitled to share equally in the Company’s profits, i.e., they have the same rights on any dividends declared on the outstanding shares of SQM.

The Company By-laws do not contain any provision relating to (a) redemption provisions (b) sinking funds or (c) liability to capital calls by the Company.

As established in article 103 of Law No. 18,046, a company subject to the supervision of the CMF may be liquidated in the following cases:

(a) Expiration of the duration term, if any, as established in its By-laws;

(b) All the shares end up in the possession of one individual for more than ten continuous days;

(c) By agreement of an Extraordinary Shareholders Meeting;

(d) By abolition, pursuant to applicable laws, of the decree that authorized its existence;

(e) Any other reason contemplated in its By-laws.

Article 40 of the Company’s By-laws states that in the event of liquidation, the shareholders’ meeting will appoint a three-member receiver committee that will have the authority to carry out the liquidation process. Any surplus will be distributed equally among the shareholders.

The only way to change the rights of the holders of the SQM shares is by modifying its By-laws, which can only be carried out by an Extraordinary Shareholders’ Meeting, as established in article 28 of the Company By-laws.

Shareholders’ Meetings

Article 29 of the Company’s By-laws states that the call to a shareholders’ meeting, either Ordinary or Extraordinary, will be by means of a highlighted public notice that will be published at least three times, and on different days, in the newspaper of the legal address determined by the shareholders’ meeting, and in the way and under the conditions indicated by the regulations. Additionally, a notice will be sent by mail to each shareholder at least fifteen days prior to the date of the Meeting, which shall include a reference of the matters to be addressed at the meeting. However, those meetings with the full attendance of the shares with right to vote may be legally held, even if the foregoing formal notice requirements are not met. Notice of any shareholders’ meeting shall be delivered to the CMF at least fifteen days in advance of such meeting.

Any holder of Series A and/or Series B shares registered in the Company’s shareholder registry on the fifth business day prior to the date of the meeting will have a right to participate at that meeting

| 122 |

Article 67 of Law No. 18,046 provides that decisions made at Extraordinary Shareholders’ Meeting on the following matters require the approval of 2/3 of the outstanding shares with voting rights: (1) transformation or division of the Company and its merger with another company; (2) modification of the Company’s term of duration, if any; (3) early dissolution of the Company; (4) change of the corporate domicile; (5) capital decrease; (6) approval of contributions and estimation of non-cash assets; (7) modification of powers reserved for Shareholders Meetings or limitations on powers of the Board of Directors; (8) reduction in the number of members of the Board of Directors; (9) disposal of 50% or more of the Company’s assets; formulation or modification of any business plan exceeding the above percentage; disposal of 50% or more of an asset belonging to a subsidiary that represents at least 20% of the Company’s assets and disposal of shares of the referred subsidiary such that the parent company would lose its position as controller of the same; (10) method in which profits are distributed; (11) granting of real or personal guarantees as sureties for third-party obligations that exceed 50% of the Company assets, except for subsidiaries, in which case approval of the Board of Directors shall suffice; (12) acquisition of own shares as set forth in articles 27A and 27B of the said law; (13) other matters indicated in the By-laws; (14) amendment of the Company By-laws as a result of errors in the constitution process and amendments in the By-laws involving one or more of the matters stated in the preceding numbers; (15) forced sale of shares carried out by the controller who would acquire more than 95% of the Company’s shares in a tender offer, and (16) approval or ratification of proceedings or contracts with related parties in accordance with the provisions of articles 44 and 147 of Law No. 18,046.

Amendments to the By-laws that are intended to create, modify, defer or suspend preferential rights shall be approved by 2/3 of the shares of the affected Series.

The transformation of the Company, the merger of the same, the disposal of assets referred to in number (9) above, the constitution of guarantees set forth in number (11) above, the constitution of preferences or the increase, postponement or decrease of the existing preferences, the reparation of formal nullities incurred in the By-laws and the possession of more than 95% of the Company’s shares and other matters contemplated in the Law or in the By-laws, confer “withdrawal rights.”

Foreign Shareholders

There exists no restriction on ownership or share concentration, or limiting the exercise of the related right to vote, by local or foreign shareholders other than those discussed under Item 10.B. Memorandum and Articles of Association.

Change in Control

The Company By-laws provide that no shareholder may hold more than 32% of the Company’s shares, unless the By-laws are modified at an Extraordinary Shareholders’ Meeting. Moreover, on December 12, 2000, the Chilean Government published the Ley de Oferta Pública de Acciones (“Public Share Offering Law”) or (OPA law) that seeks to protect the interests of minority shareholders of open stock corporations in transactions involving a change in control, by requiring that the potential new controller purchase the shares owned by the remaining shareholders either in total or pro rata. The law applies to those transactions in which the controlling party would receive a material premium price compared with the price that would be received by the minority shareholders.

There are three conditions that would make it mandatory to operate under the OPA law:

| 1) | When an investor wants to take control of a company’s stock.

| 2) | When a controlling shareholder holds two-thirds of the company’s stock. If such shareholder buys one more share, it will be mandatory to offer to acquire the rest of the outstanding stock within 30 days of surpassing that threshold.

| 3) | When an investor wants to take control of a corporation, which, in turn, controls an open stock corporation that represents 75% or more of the consolidated assets of the former corporation.

Parties interested in taking control of a company must (i) notify the company of such intention in writing, and notify its controllers, the companies controlled by it, the CMF and the markets where its stocks are traded and (ii) publish a highlighted public notice in two newspapers of national circulation at least 10 business days prior to the date of materialization of the OPA.

| 123 |

Disclosure of Share Ownership

The Company’s By-laws do not provide for a minimum threshold at which share ownership must be disclosed.

10.C. Material Contracts

The Company, during the normal course of business, has entered into different contracts, some of which have been described herein, related to its production, commercial and legal operations. We believe all of these contracts are standard for this type of industry, and none of them is expected to have a material effect on the Company’s results of operations.

10.D. Exchange Controls

The Central Bank of Chile is responsible for, among other things, monetary policies and exchange controls in Chile. Appropriate registration of a foreign investment in Chile permits the investor access to the Formal Exchange Market. Foreign investments can be registered with the Foreign Investment Committee under Decree Law No. 600 of 1974, as amended, or can be registered with the Central Bank of Chile under the Central Bank Act, Law No 18,840 of October 1989. The Central Bank Act is an organic constitutional law requiring a “special majority” vote of the Chilean Congress to be modified. Effective January 1, 2016, Decree Law No. 600 was repealed by Article 9 of the 2014 Tax Reform. Therefore, foreign investments made on or after January 1, 2016 cannot be registered with the Foreign Investment Committee.

Our 1993, 1995 and 1998 capital increases were carried out under and subject to the then current legal regulations, whose summary is hereafter included:

A ‘Convención Capítulo XXVI del Título I del Compendio de Normas de Cambios Internacionales’ or Compendium of Foreign Exchange Regulations of the Central Bank of Chile, “Foreign Investment Contract” was entered into and among the Central Bank of Chile, our Company and the Depositary, pursuant to Article 47 of the Central Bank Act and to Chapter XXVI of the Compendium of Foreign Exchange Regulations of the Central Bank of Chile, “Chapter XXVI,” which addresses the issuance of ADSs by a Chilean company. Absent the Foreign Investment Contract, under applicable Chilean exchange controls, investors would not be granted access to the Formal Exchange Market for the purposes of converting from Chilean pesos to U.S. dollars and repatriating from Chile amounts received in respect to deposited Series B shares, or Series B shares withdrawn from deposit on surrender of ADSs (including amounts received as cash dividends and proceeds from the sale in Chile of the underlying Series B shares and any rights arising therefrom). The following is a summary of the material provisions contained in the Foreign Investment Contract. This summary does not purport to be complete and is qualified in its entirety by reference to Chapter XXVI and the Foreign Investment Contract.

Under Chapter XXVI and the Foreign Investment Contract, the Central Bank of Chile has agreed to grant to the Depositary, on behalf of ADS holders, and to any investor not residing or not domiciled in Chile who withdraws Series B shares upon delivery of ADSs (such Series B shares being referred to herein as “Withdrawn Shares”) access to the Formal Exchange Market to convert Chilean pesos to U.S. dollars (and remit such U.S. dollars outside of Chile) in respect of the Withdrawn Shares, including amounts received as (a) cash dividends, (b) proceeds from the sale in Chile of Withdrawn Shares, or from shares distributed because of the liquidation, merger or consolidation of the Company, subject to receipt by the Central Bank of Chile of a certificate from the holder of such shares (or from an institution authorized by the Central Bank of Chile) that such holder’s residence and domicile are outside Chile and a certificate from a Chilean stock exchange (or from a brokerage or securities firm established in Chile) that such shares were sold on a Chilean Exchange, (c) proceeds from the sale in Chile of preemptive rights to subscribe for additional Series A and Series B shares, (d) proceeds from the liquidation, merger or consolidation of the Company and (e) other distributions, including without limitation those resulting from any recapitalization, as a result of holding Withdrawn Shares. Transferees of Withdrawn Shares will not be entitled to any of the foregoing rights under Chapter XXVI unless the Withdrawn Shares are redeposited with the Depositary. Investors receiving Withdrawn Shares in exchange for ADSs will have the right to redeposit such shares in exchange for ADSs, provided that the conditions to redeposit described hereunder are satisfied.

| 124 |

Chapter XXVI provided that access to the Formal Exchange Market in connection with dividend payments will be conditioned upon certification by the Company to the Central Bank of Chile that a dividend payment has been made and any applicable tax has been withheld. Chapter XXVI also provided that access to the Formal Exchange Market in connection with the sale of Withdrawn Shares or distributions thereon will be conditioned upon receipt by the Central Bank of Chile of certification by the Depositary that such shares have been withdrawn in exchange for ADSs and receipt of a waiver of the benefit of the Foreign Investment Contract with respect thereto until such Withdrawn Shares are redeposited.

Chapter XXVI and the Foreign Investment Contract provide that a person who brings certain types of foreign currency into Chile, including U.S. dollars, to purchase Series B shares with the benefit of the Foreign Investment Contract must convert it into Chilean pesos on the same date and has 5 banking business days within which to invest in Series B shares in order to receive the benefits of the Foreign Investment Contract. If such person decides within such period not to acquire Series B shares, he can access the Formal Exchange Market to reacquire foreign currency, provided that the applicable request is presented to the Central Bank within 7 banking business days of the initial conversion into Chilean pesos. Series B shares acquired as described above may be deposited for ADSs and receive the benefits of the Foreign Investment Contract, subject to receipt by the Central Bank of Chile of a certificate from the Depositary that such deposit has been effected and that the related ADSs have been issued and receipt by the Custodian of a declaration from the person making such deposit waiving the benefits of the Foreign Investment Contract with respect to the deposited Series B shares.

Access to the Formal Exchange Market under any of the circumstances described above is not automatic. Pursuant to Chapter XXVI, such access requires approval of the Central Bank of Chile based on a request presented through a banking institution established in Chile. The Foreign Investment Contract will provide that if the Central Bank of Chile has not acted on such request within seven banking days, the request will be deemed approved.

Under current Chilean law, foreign investments abiding by the Foreign Investment Contract cannot be changed unilaterally by the Central Bank of Chile. No assurance can be given, however, that additional Chilean restrictions applicable to the holders of ADSs, the disposition of underlying Series B shares or the repatriation of the proceeds from such disposition could not be imposed in the future, nor can there be any assessment of the duration or impact of such restrictions if imposed.

As of April 19, 2001, Chapter XXVI of Title I of the Compendio de Normas de Cambios Internacionales of the Central Bank of Chile was eliminated and new investments in ADSs by non-residents of Chile, are now governed by Chapter XIV of the Compendio de Normas de Cambios Internacionales of the Central Bank of Chile. This was made with the purpose of simplifying and facilitating the flow of capital to and from Chile. According to the new regulations, such investments must be carried out through Chile’s Formal Exchange Market and only reported to the Central Bank of Chile.

The Central Bank is also responsible for controlling incurrence of loan obligations to be paid from Chile and by a Chilean borrower to banks and certain other financial institutions outside Chile. Chapter XIV establishes what type of loans, investments, capital increases and foreign currency transactions are subject to the current Chapter XIV framework. Foreign currency transactions related to foreign loans must be performed through the Formal Exchange Market, and such transactions and the subsequent modifications of original loans must be properly informed to the Central Bank. Transactions prior to April 19, 2001, will continue to be regulated by the previous legal framework, except in cases where an express request has been presented to the Central Bank resigning previous rights to be regulated by the provisions of Chapter XIV. This summary does not purport to be complete and is qualified in its entirety by reference to the provisions of Chapter XIV.

| 125 |

As of December 31, 2017, we had bonds issued in the international markets under Rule 144A/Regulation S of US$250 million, US$250 million and US$300 million.

Any purchases of U.S. dollars in connection with payments on these loans will occur with the Formal Exchange Market. There can be no assurance, however, that restrictions applicable to payments in respect to the loans could not be imposed in the future, nor can there be any assessment of the duration or impact of such restrictions if imposed.

10.E. Taxation

Material Chilean Tax Considerations

The following describes the material Chilean income tax consequences of an investment in SQM ADSs by an individual who is not domiciled or resident in Chile or any legal entity that is not organized under the laws of Chile and does not have a permanent establishment located in Chile, a (“foreign holder”). This discussion is based upon Chilean income tax laws presently in force, including Ruling No. 324 (1990) of the Chilean Internal Revenue Service and other applicable regulations and rulings. The discussion is not intended as tax advice to any particular investor, which can be rendered only in light of that investor’s particular tax situation.

Under Chilean law, provisions contained in statutes such as tax rates applicable to foreign holders, the computation of taxable income for Chilean purposes and the manner in which Chilean taxes are imposed and collected may only be amended by another statute. In addition, the Chilean tax authorities issue rulings and regulations of either general or specific application and interpret the provisions of Chilean tax law. Chilean tax may not be assessed retroactively against taxpayers who act in good faith relying on such rulings, regulations and interpretations, but Chilean tax authorities may change said rulings, regulations and interpretations prospectively.

Cash Dividends and Other Distributions

On September 29, 2014, the Tax Reform was published, introducing significant changes to the Chilean taxation system and strengthening the powers of the SII to control and prevent tax avoidance. Subsequently, on February 8, 2016, Law No. 20,899 that simplifies the income tax system and modifies other legal tax provisions was published. As a result of these reforms, open stock corporations like SQM are subject to the partially integrated shareholder tax regime (sistema parcialmente integrado). The corporate tax rate applicable to us increased to 25.5% in 2017. It will increase to a maximum rate of 27% in 2018.

Under the partially integrated shareholder taxation regime, shareholders bear the tax on dividends upon payment, but they will only be permitted to credit against such shareholder taxes a portion of the Chilean corporate tax paid by us on our earnings, unless the shareholder is resident in a country with a tax treaty in force with Chile or signed with Chile prior to January 1, 2017, whether or not in force. In that case, 100% of the Chilean corporate tax paid by us may be credited against the final taxes at the shareholder level.

As a result, foreign shareholders, resident in a non-treaty jurisdiction will be subject to a higher effective tax rate than residents of treaty jurisdictions. There is a temporary rule in effect from January 1, 2017 through December 31, 2019 that treaty jurisdictions for this purpose will include jurisdictions with tax treaties signed with Chile prior to January 1, 2017, whether or not such treaties are in force. This is currently the status of the treaty signed between Chile and United States.

| 126 |

Cash dividends paid by the Company with respect to the shares, including shares represented by ADSs held by a U.S. Holder (as defined below), will be subject to a 35% Chilean withholding tax, which is withheld and paid by the Company (the “Withholding Tax”). The effective rate of Withholding Tax imposed on dividends attributed to 2017 earnings of the Company and distributed during the same period was 18.25444%.

Capital Gains

Gains from the sale or other disposition by a foreign holder of ADSs outside Chile will not be subject to Chilean taxation. The deposit and withdrawal of the shares in exchange for ADRs will not be subject to any Chilean taxes.

The tax basis of the shares received in exchange for ADSs (repatriation) will be the acquisition value of the shares. The Series B shares exchanged for ADSs are valued at the highest price at which they trade on the Chilean Stock Exchange on the date of the exchange or on either of the two business days preceding the exchange. Consequently, the conversion of ADSs into the shares and the immediate sale of such shares at a price equal to or less than the highest price for Series B shares on the Chilean Stock Exchange on such dates will not generate a gain subject to Chilean taxation.

Gain recognized on a sale or exchange of shares (as distinguished from sales or exchanges of ADSs representing such shares) will be subject to both the First Category Tax and the Withholding Tax if either (i) the foreign holder has held the shares for less than one year since exchanging the ADSs for the shares, (ii) the foreign holder acquired and disposed of the shares in the ordinary course of its business or as a regular trader of shares, or (iii) the foreign holder and the purchaser of the shares are related parties within the meaning of Chilean tax law. The amount of the First Category Tax may be credited against the amount of the Withholding Tax. In all other cases, gain on the disposition of the shares will be subject only to a capital gains tax, which is assessed at the same rate as the First Category Tax. Gain recognized in the transfer of common shares that have significant trading volumes in the stock exchange, however, is not subject to capital gains tax in Chile, provided that the common shares are transferred in a local stock exchange authorized by the CMF, within the process of a public tender of common shares governed by the Chilean Securities Market Act. Law No. 20,448 states that common shares must also have been acquired after April 19, 2001, either on a local stock exchange authorized by the CMF, within the referred process of public tender of a common shares governed by the Chilean Securities Market Act, in an initial public offering of common shares resulting from the formation of a corporation or a capital increase of the same, in an exchange of convertible securities subject to public offer, or in the redemption of mutual funds shares. According to Ruling No. 224 (2008) of the Chilean Internal Revenue Service, common shares received by exchange of ADRs are also considered as “acquired on a stock exchange” if the respective ADRs have been acquired on a foreign stock exchange authorized by the CMF (i.e., London Stock Exchange, New York Stock Exchange and Bolsa de Valores de Madrid). Common shares are considered to have a high presence in the stock exchange when they: (a) are registered in the Securities Registry, (b) are registered in a Chilean Stock Exchange, (c) have an adjusted presence equal to or above 25%.

As of June 19, 2001, capital gains obtained in the sale of common shares that are publicly traded in a stock exchange are also exempt from capital gains tax in Chile when the sale is made by “foreign institutional investors” such as mutual funds and pension funds, provided that the sale is made in a local stock exchange authorized by the CMF, or in accordance with the provisions of the securities market law (Law 18,045). To qualify as foreign institutional investors, the referred entities must be formed outside of Chile, not have a domicile in Chile, and they must be an “investment fund” in according with the Chilean tax law.

| 127 |

Starting January 1, 2017, capital gains obtained in the sales of shares owned by foreign holders are subject to First Category Tax and Withholding Tax, and the First Category Tax serves as a credit in Chile to reduce the Withholding Tax. The exercise of preemptive rights relating to shares will not be subject to Chilean taxation. Any gain on the sale or assignment of preemptive rights relating to shares will be subject to both the First Category Tax and the Withholding Tax (the former being creditable against the latter).

Other Chilean Taxes

No Chilean inheritance, gift or succession taxes apply to the transfer or disposition of the ADSs by a foreign holder, but such taxes generally will apply to the transfer at death or by gift of the shares by a foreign holder. No Chilean stamp, issue, registration or similar taxes or duties apply to foreign holders of ADSs or shares.

Withholding Tax Certificates

Upon request, the Company will provide to foreign holders appropriate documentation evidencing the payment of Chilean withholding taxes.

Material U.S. Federal Income Tax Considerations

The following discussion summarizes the material U.S. federal income tax consequences to U.S. Holders (defined below) arising from ownership and disposition of the Series A shares and the Series B common shares, together the “shares”, and the ADSs. The discussion which follows is based on the U.S. Internal Revenue Code of 1986, as amended, the “Code,” the Treasury regulations promulgated thereunder, and judicial and administrative interpretations thereof, all as in effect and available on the date hereof. These authorities are subject to change, possibly with retroactive effect, which could affect the continued validity of this summary. In addition, the summary assumes that the depositary’s activities are clearly and appropriately defined so as to ensure that the tax treatment of ADSs will be identical to the tax treatment of the underlying shares.

The discussion that follows is not intended as tax advice to any particular investor and is limited to investors who will hold the shares or ADSs as “capital assets” within the meaning of Section 1221 of the Code and whose functional currency is the U.S. dollar. The summary does not address the tax treatment of holders that may be subject to special U.S. federal income tax rules, such as insurance companies, tax-exempt organizations, financial institutions, persons who are subject to the alternative minimum tax, persons who are broker-dealers in securities or foreign currency or dealers and traders in securities who use a mark-to-market method of tax accounting, persons who hold the shares or ADSs as a hedge against currency risks, as a position in a “straddle” for tax purposes, or as part of a conversion or other integrated transaction, persons holding our shares or ADSs in connection with a trade or business conducted outside of the U.S., partnerships or other entities classified as partnerships or other pass-through entities for U.S. federal income tax purposes, or persons who own (directly, indirectly or by attribution) 10% or more of the combined voting power of all classes of equity in the Company or 10% or more of the combined value of all classes of equity in the Company.

For purposes of this summary, the term “U.S. Holder” means a beneficial owner of shares or ADSs that is, for U.S. federal income tax purposes, (a) an individual who is a U.S. citizen or resident, (b) a corporation or other entity taxable as a corporation created or organized under the laws of the U.S. or any political subdivision thereof, (c) an estate, the income of which is subject to U.S. federal income tax regardless of the source, or (d) a trust (i) that validly elects to be treated as a U.S. person for U.S. federal income tax purposes or (ii) if (A) a court within the U.S. is able to exercise primary supervision over the administration of the trust and (B) one or more U.S. persons have the authority to control all substantial decisions of the trust.

| 128 |

If a partnership (or any other entity treated as a partnership for U.S. federal income tax purposes) holds shares or ADSs, the tax treatment of the partnership and a partner in such partnership generally will depend on the status of the partner and the tax treatment of the partnership. Such a partner or partnership should consult its own tax advisor as to its consequences.

As of this date, there is currently no applicable income tax treaty in effect between the U.S. and Chile. However, in 2010, the U.S. and Chile signed an income tax treaty that will enter into force once the treaty is ratified by both countries. There can be no assurance that the treaty will be ratified by either country. The following summary assumes that there is no applicable income tax treaty in effect between the U.S. and Chile.

The discussion below does not address the effect of any U.S. state, local, estate or gift tax law or non-U.S. tax law or tax considerations that arise from rules of general application to all taxpayers on a U.S. Holder of the shares or ADSs. U.S. HOLDERS OF SHARES OR ADSs SHOULD CONSULT THEIR OWN TAX ADVISORS TO DETERMINE THE PARTICULAR CONSEQUENCES UNDER ANY SUCH LAW OF OWNING OR DISPOSING THE SHARES OR ADSs.

For purposes of applying U.S. federal income tax law, any U.S. Holder of an ADS generally will be treated as the owner of the underlying shares represented thereby. The U.S. Treasury has expressed concerns that parties to whom ADSs are released before shares are delivered to the depositary (pre-release) or intermediaries in the chain of ownership between beneficial owners and the issuer of the security underlying the ADSs may be taking actions that are inconsistent with the claiming of foreign tax credits for beneficial owners of depositary shares. Such actions would also be inconsistent with the claiming of the reduced tax rate, described below, applicable to dividends received by certain non-corporate beneficial owners. Accordingly, the analysis of the creditability of Chilean taxes, and the availability of the reduced tax rate for dividends received by certain non-corporate holders, each described below, could be affected by actions taken by such parties or intermediaries.

Cash Dividends and Other Distributions

The following discussion of cash dividends and other distributions is subject to the discussion below under “Passive Foreign Investment Company Rules.” Distributions received by a U.S. Holder on shares or ADSs, including the amount of any Chilean taxes withheld, other than certain pro rata distributions of shares to all shareholders, will constitute foreign-source income to the extent paid out of our current or accumulated earnings and profits (as determined for U.S. federal income tax purposes). Because we do not maintain calculations of our earnings and profits under U.S. federal income tax principles, it is expected that distributions generally will be reported to U.S. Holders as dividends. The amount of dividend income paid in Chilean pesos that a U.S. Holder will be required to include in income will equal the U.S. dollar value of the distributed Chilean peso, calculated by reference to the exchange rate in effect on the date the payment is received, regardless of whether the payment is converted into U.S. dollars on the date of receipt. If the dividend is converted into U.S. dollars on the date of receipt, a U.S. Holder will generally not be required to recognize foreign currency gain or loss in respect of the dividend income. A U.S. Holder may have foreign currency gain or loss if the dividend is converted into U.S. dollars after the date of its receipt, which would be ordinary income or loss and would be treated as income from U.S. sources for foreign tax credit purposes. Dividends will be included in a U.S. Holder’s income on the date of the U.S. Holder’s, or in the case of ADSs, the depositary’s, receipt of the dividend. Corporate U.S. Holders will not be entitled to claim the dividends-received deduction with respect to dividends paid by us.

| 129 |

Subject to certain exceptions for short-term and hedged positions, the discussion above regarding concerns expressed by the U.S. Treasury and the discussion below regarding rules intended to be promulgated by the U.S. Treasury, the U.S. dollar amount of dividends received by a noncorporate U.S. Holder in respect of our shares or ADSs generally will be subject to taxation at preferential rates if the dividends are “qualified dividends.” Dividends paid on our ADSs generally will be treated as qualified dividends if (i) our ADSs are readily tradable on an established securities market in the U.S. (ii) SQM was not, in the year prior to the year in which the dividend was paid, and is not, in the year in which the dividend is paid, a passive foreign investment company (“PFIC”) and (iii) the holder thereof has satisfied certain holding period requirements. Our ADSs are listed on the New York Stock Exchange and generally will qualify as readily tradable on an established securities market in the U.S. so long as they are so listed. We do not believe that we were a PFIC for U.S. federal income tax purposes with respect to our 2017 taxable year. In addition, based on our current expectations regarding the value and nature of our assets, the sources and nature of our income, and relevant market and shareholder data, we do not anticipate becoming a PFIC for our 2018 taxable year. However, because PFIC status depends upon the composition of a company’s income and assets and the market value of its assets from time to time, and because it is unclear whether certain types of our income constitute passive income for PFIC purposes, there can be no assurance that we will not be considered a PFIC for any current, prior or future taxable year. Based on existing guidance, it is not entirely clear whether dividends received with respect to our shares will be treated as qualified dividends, because our shares are not themselves listed on a U.S. exchange. In addition, the U.S. Treasury has announced its intention to promulgate rules pursuant to which holders of ADSs and intermediaries through whom such securities are held will be permitted to rely on certifications from issuers to establish that dividends are treated as qualified dividends. Because such procedures have not yet been issued, it is not clear whether we will be able to comply with them. A U.S. HOLDER SHOULD CONSULT ITS TAX ADVISORS TO DETERMINE WHETHER THE FAVORABLE RATE WILL APPLY TO DIVIDENDS IT RECEIVES AND WHETHER IT IS SUBJECT TO ANY SPECIAL RULES THAT LIMIT ITS ABILITY TO BE TAXED AT THIS FAVORABLE RATE.

The amount of a dividend generally will be treated as foreign-source dividend income to a U.S. Holder for foreign tax credit purposes. As discussed in more detail below under “—Foreign Tax Credits,” it is not free from doubt whether Chilean withholding taxes imposed on distributions on our shares or ADSs will be treated as income taxes eligible for a foreign tax credit for U.S. federal income tax purposes. If a Chilean withholding tax is treated as an eligible foreign income tax, subject to generally applicable limitations, you may claim a credit against your U.S. federal income tax liability for the eligible Chilean taxes withheld from distributions on our shares or ADSs. If the dividends are taxed as qualified dividend income (as discussed above), special rules will apply in determining the amount of the dividend taken into account for purposes of calculating the foreign tax credit limitation. THE RULES RELATING TO FOREIGN TAX CREDITS ARE COMPLEX. YOU ARE URGED TO CONSULT YOUR OWN TAX ADVISORS REGARDING THE TREATMENT OF CHILEAN WITHHOLDING TAXES IMPOSED ON DISTRIBUTIONS ON OUR SHARES OR ADSs.

Sale or Other Disposition of our Shares or ADSs

For U.S. federal income tax purposes, the gain or loss a U.S. Holder realizes on the sale or other disposition of our shares or ADSs generally will be U.S.-source capital gain or loss for foreign tax credit purposes, and generally will be a long-term capital gain or loss if the U.S. Holder has held our shares or ADSs for more than one year. The amount of a U.S. Holder’s gain or loss will equal the difference between the U.S. Holder’s tax basis in our shares or ADSs disposed of and the amount realized on the disposition (including any amount withheld in respect of Chilean withholding taxes), in each case as determined in U.S. dollars.

In certain circumstances, Chilean taxes may be imposed upon the sale of shares. See “—Material Chilean Tax Considerations—Capital Gains” above. As discussed in more detail below under “—Foreign Tax Credits,” subject to generally applicable limitations and substantiation requirements, a U.S. Holder may claim a credit against its U.S. federal income tax liability for the eligible Chilean taxes withheld pursuant to a sale or other disposition of our shares or ADSs. U.S. HOLDERS ARE URGED TO CONSULT THEIR OWN U.S. TAX ADVISORS WITH RESPECT TO THE PARTICULAR CONSEQUENCES TO THEM OF OWNING OR DISPOSING OF OUR SHARES OR ADSs.

| 130 |

Foreign Tax Credits

Subject to applicable limitations that may vary depending upon a U.S. Holder’s circumstances and subject to the discussion above regarding concerns expressed by the U.S. Treasury, you may claim a credit against your U.S. tax liability for Chilean income taxes (or taxes imposed in lieu of an income tax) imposed in connection with distributions on and proceeds from the sale or other disposition of our shares or ADSs. Chilean dividend withholding taxes generally are expected to be income taxes eligible for the foreign tax credit. The Chilean capital gains tax is likely to be treated as an income tax (or a tax paid in lieu of an income tax) and thus eligible for the foreign tax credit; however, you generally may claim a foreign tax credit only after taking into account any available opportunity to reduce the Chilean capital gains tax, such as the reduction for the credit for Chilean corporate income tax that is taken into account when calculating Chilean withholding tax. If a Chilean tax is imposed on the sale or disposition of our shares or ADSs, and a U.S. Holder does not receive significant foreign source income from other sources, such U.S. Holder may not be able to credit such Chilean tax against its U.S. federal income tax liability. If a Chilean tax is not treated as an income tax (or a tax paid in lieu of an income tax) for U.S. federal income tax purposes, a U.S. Holder would be unable to claim a foreign tax credit for any such Chilean tax withheld; however, a U.S. Holder may be able to deduct such tax in computing its U.S. federal income tax liability, subject to applicable limitations. In addition, instead of claiming a credit, a U.S. Holder may, at the U.S. Holder’s election, deduct such Chilean taxes in computing the U.S. Holder’s taxable income, subject to generally applicable limitations under U.S. law. An election to deduct foreign taxes instead of claiming foreign tax credits applies to all taxes paid or accrued in the taxable year to foreign countries and possessions of the U.S. THE CALCULATION OF FOREIGN TAX CREDITS AND, IN THE CASE OF A U.S. HOLDER THAT ELECTS TO DEDUCT FOREIGN INCOME TAXES, THE AVAILABILITY OF DEDUCTIONS, INVOLVES THE APPLICATION OF COMPLEX RULES THAT DEPEND ON YOUR PARTICULAR CIRCUMSTANCES. U.S. HOLDERS ARE URGED TO CONSULT THEIR TAX ADVISORS REGARDING THE AVAILABILITY OF FOREIGN TAX CREDITS IN THEIR PARTICULAR CIRCUMSTANCES.

Passive Foreign Investment Company Rules

We do not expect to be a PFIC for U.S. federal income tax purposes for our 2018 taxable year or for the foreseeable future. However, because PFIC status depends upon the composition of a company’s income and assets and the market value of its assets from time to time, and because it is unclear whether certain types of our income constitute passive income for PFIC purposes, there can be no assurance that we will not be considered a PFIC for any current, prior or future taxable year. If we were a PFIC for any taxable year during which a U.S. Holder held our shares or ADSs, certain adverse consequences could apply to the U.S. Holder, including the imposition of higher amounts of tax than would otherwise apply, and additional filing requirements. In addition, if we were treated as a PFIC in a taxable year in which we pay a dividend or in the prior taxable year, the favorable dividend rates discussed above with respect to dividends paid to certain non-corporate U.S. Holders would not apply (see “—Cash Dividends and Other Distributions” above). A U.S. Holder should consult its tax advisors regarding the consequences to it if we were a PFIC, as well as the availability and advisability of making any election that might mitigate the adverse consequences of PFIC status.

Controlled Foreign Corporation Rules

A foreign corporation will be treated as a “controlled foreign corporation” (“CFC”) for U.S. federal income tax purposes if, on any day during the taxable year of such foreign corporation, more than 50% of the equity interests in such corporation, measured by reference to the combined voting power or value of the equity of the corporation, is owned directly or by application of the attribution and constructive ownership rules of Sections 958(a) and 958(b) of the Code by U.S. Shareholders. For this purpose, a “United States Shareholder” is any United States person that possesses directly, or by application of the attribution and constructive ownership rules of Sections 958(a) and 958(b) of the Code, 10% or more of the combined voting power of all classes of equity in such corporation or 10% or more of the combined value of all classes of equity in such corporation. If a foreign corporation is a CFC at any time during any taxable year, each United States Shareholder of the corporation who owns, directly or indirectly, shares in the corporation on the last day of the taxable year on which it is a CFC will be required to include in its gross income for U.S. federal income tax purposes its pro rata share of the CFC’s “Subpart F income” for such year, even if the Subpart F income is not distributed. Subpart F income generally includes passive income but also includes certain related party sales, manufacturing and services income. For tax years beginning after December 31, 2017, H.R. 1, originally known as the “Tax Cuts and Jobs Act,” (the “TCJA”) also requires such United States Shareholders to include in their gross income for U.S. federal income tax purposes their pro rata share of certain global intangible low-tax income. The calculation of global intangible low-taxed income is complex, and involves calculations regarding other controlled foreign corporations in which a U.S. Holder is a United States Shareholder. Further, certain changes to the 133 CFC constructive ownership rules under Section 958(b) of the Code introduced by the TCJA may cause one or more of our non-U.S. subsidiaries to be treated as CFCs, may also impact our CFC status, and may affect holders of our shares or ADSs that are United States Shareholders. U.S. HOLDERS WHO MIGHT, DIRECTLY, INDIRECTLY OR CONSTRUCTIVELY, ACQUIRE 10% OR MORE OF OUR SHARES (BY VOTE OR VALUE), AND THEREFORE MIGHT BE A UNITED STATES SHAREHOLDER, SHOULD CONSIDER THE POSSIBLE APPLICATION OF THE CFC RULES, AND ARE URGED TO CONSULT A TAX ADVISOR WITH RESPECT TO SUCH MATTER.

Information Reporting and Backup Withholding

Required Disclosure with Respect to Foreign Financial Assets

Certain U.S. Holders are required to report information relating to an interest in our shares or ADSs, subject to certain exceptions (including an exception for our shares or ADSs held in accounts maintained by certain financial institutions), by attaching a completed IRS Form 8938, Statement of Specified Foreign Financial Assets, with their tax return for each year in which they hold an interest in our shares or ADSs. U.S. HOLDERS ARE URGED TO CONSULT THEIR OWN U.S. TAX ADVISORS REGARDING INFORMATION REPORTING REQUIREMENTS RELATING TO THEIR OWNERSHIP OF OUR SHARES OR ADSs.

Information Reporting and Backup Withholding

Payments of dividends and sales proceeds that are made within the U.S. or through certain U.S.-related financial intermediaries generally are subject to information reporting and to backup withholding unless (i) the U.S. Holder is an exempt recipient or (ii) in the case of backup withholding, the U.S. Holder provides a correct taxpayer identification number and certifies that it is not subject to backup withholding.

The amount of any backup withholding from a payment to a U.S. Holder will be allowed as a credit against its U.S. federal income tax liability and may entitle it to a refund, provided that the required information is timely furnished to the U.S. Internal Revenue Service.

A U.S. HOLDER SHOULD CONSULT ITS OWN TAX ADVISORS WITH RESPECT TO THE PARTICULAR CONSEQUENCES TO IT OF OWNING AND DISPOSING OF OUR SHARES OR ADSs.

Medicare Contribution Tax

Legislation enacted in 2010 generally imposes a tax of 3.8% on the “net investment income” of certain individuals, trusts and estates. Among other items, net investment income generally includes gross income from dividends and net gain attributable to the disposition of certain property, like our shares or ADSs, less certain deductions. A U.S. Holder should consult the U.S. Holder’s tax advisor regarding the possible application of this legislation in the U.S. Holder’s particular circumstances.

| ITEM 11. | QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

As explained elsewhere in this Annual Report, we transact our businesses in more than 110 countries, thereby rendering our market risk dependent upon the fluctuations of foreign currencies and local and international interest rates. These fluctuations may generate losses in the value of financial instruments taken in the normal course of business.

We, from time to time and depending upon then current market conditions, review and re-establish our financial policies to protect our operations. Management is authorized by our Board of Directors to engage in certain derivative contracts such as forwards and swaps to specifically hedge the fluctuations in interest rates and in currencies other than the U.S. dollar.

Derivative instruments used by us are generally transaction-specific so that a specific debt instrument or contract determines the amount, maturity and other terms of the hedge. We do not use derivative instruments for speculative purposes.

Interest Rate Risk. As of December 31, 2017, we did not have any financial debt effectively priced at LIBOR. Interest rate fluctuations, due to the uncertain future behavior of markets, may have a material impact on our financial results should we have such debts.

As of December 31, 2017, our total financial debt is primarily long-term, with 14% of maturities less than 12 months, which we believe decreases the exposure to changes in the interest rates.

Exchange Rate Risk. Although the U.S. dollar is the primary currency in which we transact our businesses, our operations throughout the world expose us to exchange rate variations for non-U.S. dollar currencies. Therefore, fluctuations in the exchange rate of such local currencies may affect our financial condition and results of operations. To lessen these effects, we maintain derivative contracts to protect the net difference between our principal assets and liabilities for currencies other than the U.S. dollar. These contracts are renewed periodically depending on the amount covered in each currency. Aside from this, we do not hedge potential future income and expenses in currencies other than the U.S. dollar with the exception of the Euro and Chilean peso. We estimate annual sales in Euros and expenses in Chilean pesos, and depending on the circumstances we secure the exchange difference with derivative contracts.

The following is a summary of the aggregate net monetary assets and liabilities that are denominated in non-U.S. dollar currencies as of December 31, 2017, 2016 and 2015. Figures do not include our financial hedging positions for year-end:

Also, we had open forward exchange contracts to buy U.S. dollars and sell Chilean pesos to hedge our time deposits in Chilean pesos for approximately US$550 million (Ch$351,416 million).

| ITEM 15. | CONTROLS AND PROCEDURES

| (a) | Disclosure Control and Procedures

SQM management, with the participation of the Company’s Chief Executive Officer and Chief Financial Officer and other members of the Company’s executive management, evaluated the effectiveness of our disclosure controls and procedures, pursuant to Rule 13a-15(b) promulgated under the Exchange Act, as of the end of the period covered by this Annual Report. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that the Company’s disclosure controls and procedures were effective in providing reasonable assurance that material information is made known to management and that financial and non-financial information is properly recorded, processed, summarized and reported as of December 31, 2017.

The Company’s disclosure controls and procedures are designed to provide reasonable assurance that information required to be disclosed by the issuer in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the Commission’s rules and forms, and that such information is accumulated and communicated to management of the Company, with the participation of its Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosures. However, through the same design and evaluation period of the disclosure controls and procedures, the Company’s management, including the Company’s Chief Executive Officer and Chief Financial Officer, recognized that there are inherent limitations to the effectiveness of any control system regardless of how well designed and operated. In such a way they can provide only reasonable assurance of achieving the desired control objectives, and no evaluation can provide absolute assurance that all control issues or instances of fraud, if any, within the Company have been detected.

| (b) | Management’s Annual Report on Internal Control Over Financial Reporting

SQM management is responsible for establishing and maintaining adequate internal control over financial reporting as such term is defined in Exchange Act Rule 13a-15(f). The Company’s internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of the financial statements for external purposes in accordance with generally accepted accounting principles.

Because of its inherent limitations, internal control over financial reporting may not necessarily prevent or detect some misstatements. It can only provide reasonable assurance regarding financial statement preparation and presentation. Also, projections of any evaluation of effectiveness for future periods are subject to the risk that controls may become inadequate because of changes in conditions or because the degree of compliance with the polices or procedures may deteriorate over time.

Management assessed the effectiveness of its internal control over financial reporting as of December 31, 2017. The assessment was based on criteria established in the framework “Internal Controls — Integrated Framework (2013)” issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on the assessment, SQM management has concluded that as of December 31, 2017, the Company’s internal control over financial reporting was effective.

| (c) | Attestation Report of the Registered Public Accounting Firm

For the report of PricewaterhouseCoopers Consultores Auditores SpA, independent registered public accounting firm, dated April 19, 2018, on the effectiveness of our internal control over financial reporting as of December 31, 2017, see page F-2 of our Audited Consolidated Financial Statements.

| (d) | Changes in Internal Control Over Financial Reporting

There has been no change in the Company’s internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) that occurred during the period covered by this Annual Report that has materially affected, or is reasonably likely to materially affect, internal control over financial reporting.

| ITEM 16. | [Reserved]

| ITEM 16A. | AUDIT COMMITTEE FINANCIAL EXPERT

The Board of Directors has determined that the Company does not have an audit committee financial expert within the meaning of the regulations adopted under the Sarbanes-Oxley Act of 2002.

Pursuant to Chilean regulations, the Company has a Directors’ Committee whose main duties are similar to those of an audit committee. Each of the members of the Directors’ Committee is a member of the audit committee. See “Item 6.C. Board Practices.”

Our Board believes that the members of the Directors’ Committee have the necessary expertise and experience to perform the functions of the Directors’ Committee pursuant to Chilean regulations.

| ITEM 16B. | CODE OF ETHICS

We have adopted a Code of Business Conduct that applies to the Chief Executive Officer, the Chief Financial Officer, the Internal Auditor as well as all our officers and employees. Our Code adheres to the definition set forth in Item 16B. of Form 20-F under the Exchange Act.

No waivers have been granted therefrom to the officers mentioned above.

The full text of the code is available on our website at http://www.sqm.com in the Investor Relations section under “Corporate Governance.”

Amendments to, or waivers from one or more provisions of the code will be disclosed on our website.

| ITEM 16C. | PRINCIPAL ACCOUNTANT FEES AND SERVICES

The table shows the amount of fees billed to SQM by our independent auditors, PwC for the 2017 and 2016 fiscal years, in relation to audit and tax services provided to us (in thousands of US$) (excluding amounts related to the pre-approved non-audit services referred to below):

|  | 2017 |  |  | 2016 |
Audit fees |  |  | 1,599 |  |  |  | 1,488 |
Tax fees |  |  | 265 |  |  |  | 176 |
All other fees |  |  | 36 |  |  |  | 109 |
Total fees |  |  | 1,900 |  |  |  | 1,664 |

| 136 |

Audit and tax fees in the above table are the aggregate fees approved by the Directors’ Committee for PwC in 2017 and 2016 in connection with the audit of our annual Consolidated Financial Statements, as well as the review of other statutory filings excluding the non-audit related fees described in the below paragraph.

All other fees in the above table are aggregate fees approved by the Directors’ Committee for PwC in 2017 and 2016 in connection with services such as transfer pricing and other services that were not related to audit or tax.

All of the fees disclosed in the table above were pre-approved by the Directors’ Committee pre-approval policies and procedures.

Directors’ Committee Pre-Approval Policies and Procedures.

Chilean law states that public companies are subject to “pre-approval” requirements under which all audit and non-audit services provided by the independent auditor must be pre-approved by the Directors’ Committee. Our Directors’ Committee approves all audits, audit-related, tax and other services provided by our auditors.

Any services provided by our auditors that are not specifically included within the scope of the audit must be pre-approved by the Directors’ Committee prior to any engagement.

| ITEM 16D. | EXEMPTIONS FROM THE LISTING STANDARDS FOR AUDIT COMMITTEES

Our Directors’ Committee performs many of the functions of an audit committee under NYSE corporate governance rules and the Exchange Act but also performs other functions as prescribed under Chilean law. See “Item 6.C. Board Practices.”

Ms. Joanne L. Boyes was an executive officer of Nutrien (formerly PCS prior to the merger with Agrium Inc. on January 1, 2018) during her service on our Directors’ Committee. Nutrien and its affiliates owned and currently owns an aggregate of 32% of the total outstanding shares of SQM. See “Item 7.A. Major Shareholders.”

Ms. Boyes resigned from our Directors’ Committee and Board of Directors on January 24, 2018. During her service on the Directors’ Committee, Ms. Boyes served as an observer on audit committee matters and did not have voting rights on such matters. Ms. Boyes was neither the chair of the Directors’ Committee nor an executive officer of SQM. Accordingly, we relied on the exemption provided in Rule 10A-3(b)(1)(iv)(D) of the Exchange Act for Ms. Boyes’ service on the Directors’ Committee. We do not believe that Ms. Boyes’ affiliation with Nutrien had a materially adverse effect on the ability of the Directors’ Committee to act independently or to satisfy the other requirements relating to audit committees contained in Rule 10A-3 under the Exchange Act.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders of Sociedad Química y Minera de Chile S.A.

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated statements of financial position of Sociedad Química y Minera de Chile S.A. and Subsidiaries (“the Company”) as of December 31, 2017 and 2016, and the related consolidated statements of income, comprehensive income, changes in equity and cash flows for each of the three years in the period ended December 31, 2017, including the related notes (collectively referred to as the “consolidated financial statements”). We also have audited the Company’s internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2017 and 2016, and the results of their operations and their cash flows for each of the three years in the period ended December, 31, 2017 in conformity with International Financial Reporting Standards as issued by the International Accounting Standards Board. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO.

Basis for Opinions

The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Report on Internal Control over Financial Reporting. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company's internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) ("PCAOB") and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

| F-1 |

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Notes to the Consolidated Financial Statements as of December 31, 2017

| Note 1 | Identification and Activities of the Company and Subsidiaries (continued)

| 1.4 | Description of the nature of operations and main activities, continued

From our caliche ore deposits located in the north of Chile, we produce a wide range of nitrate-based products used for specialty plant nutrients and industrial applications, as well as iodine and iodine derivatives. At the Salar de Atacama, we extract brines rich in potassium, lithium and sulfate in order to produce potassium chloride, potassium sulfate, lithium solutions, and bischofite (magnesium chloride). We produce lithium carbonate and lithium hydroxide at our plant near the city of Antofagasta, Chile, from the solutions brought from the Salar de Atacama.

We sell our products in over 100 countries worldwide through our global distribution network and generate our revenue mainly from abroad.

Our products are divided into six categories: specialty plant nutrition, iodine and its derivatives, lithium and its derivatives, industrial chemicals, potassium and other products and services, described as follows:

Specialty plant nutrition: SQM produces and sells four types of specialty plant nutrition in this line of business: potassium nitrate, sodium nitrate, sodium potassium nitrate, and specialty mixes. This business is characterized by being closely related to its customers for which it has specialized staff who provide expert advisory in best practices for fertilization according to each type of crop, soil and climate. Within this type of business, potassium derivative products and especially potassium nitrate have had a leading role because of the contribution they make to developing crops, ensuring an improvement in post-crop life, in addition to improving quality, flavor and fruit color. The potassium nitrate, which is sold in multiple formats and as a part of other specialty mixtures, is complemented by sodium nitrate, potassium sodium nitrate, and more than 200 fertilizing mixtures.

Iodine: The Company is a major global producer of iodine. Iodine is widely used in the pharmaceutical industry, technology and nutrition. Additionally, iodine is used as X ray contrast media and polarizing film for LCD displays.

Lithium: The Company’s lithium is mainly used for manufacturing rechargeable batteries for cell phones, cameras and notebooks. By manufacturing lithium-based products, SQM provides significant materials for addressing great challenges, such as the efficient use of energy and raw materials. Lithium is not only used for rechargeable batteries for small electrical appliances such as mobile phones, tablets and laptops, but is also used in industrial applications, such as the manufacturing of glass, ceramics and lubricating greases. Other uses include the pharmaceutical and chemical industries.

Notes to the Consolidated Financial Statements as of December 31, 2017

| Note 1 | Identification and Activities of the Company and Subsidiaries (continued)

| 1.4 | Description of the nature of operations and main activities, continued

Industrial chemicals: Industrial chemicals are products used as supplies for a number of production processes. SQM participates in this line of business producing sodium nitrate, potassium nitrate and potassium chloride. Industrial nitrates have increased their importance over the last few years due to their use as storage means for thermal energy at solar energy plants, which are widely used in countries such as Spain and the United States in their quest to decrease CO2 emissions.

Potassium: Potassium is a primary essential macro-nutrient, and even though does not form part of the plant’s structure, it has a significant role for the development of its basic functions, ensuring the quality of a crop, increasing post-crop life, improving crop flavor, the amount of vitamins it contains and its physical appearance. Within this business line, SQM also has potassium chlorate and potassium sulfate, both extracted from the salt layer located under the Salar de Atacama (the Atacama Saltpeter Deposit).

Other products and services: This business line includes revenue from commodities, services, interests, royalties and dividends.

Standards and interpretations |  | Mandatory for annual periods beginning on
The International Financial Reporting Standard No. 9 (IFRS 9) Financial Instruments - Published in July 2014. The IASB has published a complete new version of IFRS 9, which replaces the guidance in IAS 39. This final version includes requirements regarding the classification and measurement of financial assets and liabilities and a new model for the recognition of expected credit losses that replaces the incurred loss impairment model used today. The part relating to hedge accounting that forms part of this final version of IFRS 9 was published in November 2013. Adoption effects are disclosed as follows: |  | 01/01/2018
i. The classification of financial assets depends on the entity´s business model for managing its financial assets and the characteristics of the contractual cash flow of financial assets. No significant change was derived from the new established classification of IFRS 9. |  |
ii. The Company’s trade receivables are maintained to obtain contractual cash flows (charge and collect) and do not contain a significant financing component, being recognized at the transaction price defined in IFRS 15. Meanwhile, the Company is using the simplified approach for recognizing expected credit losses if there is no significant increase in the credit risk since initial recognition and the terms of sale are less than 12 months. Similarly, the Company is using an impairment model for trade receivables based on expected credit losses that considers the credit risk separately from its hedges, generating non-significant difference compared to that established in the previous accounting standard IAS 39. |  |
iii. The Company will continue applying the hedge accounting requirements established in IAS 39, as permitted by IFRS 9. |  |
The Company has established the procedures and controls for beginning to apply IFRS 9 as of January 1, 2018. |  |

Standards and interpretations |  | Mandatory for annual periods beginning on
The International Financial Reporting Standard No. 15 (IFRS 15) Revenue from Contracts with Customers - Published in May 2014 by the IASB. This established the principles that an entity must apply for presenting useful information to users of financial statements with regard to the nature, amount, timing and uncertainty of revenue and cash flows from a contract with a customer, as of January 1, 2018. The basic principle is that an entity will recognize revenue representing the transfer of goods or services to customers in an amount that reflects the consideration that the entity expects to receive in exchange for such goods or services. The new standard establishes a framework of five steps to determine when to recognize revenue and at what amount. The standard is focused on recognizing the revenue as the different obligations of performance, transfer of control, risks and benefits are fulfilled. This standard replaces the following standards and interpretations: IAS 18 Revenue; IAS 11 Construction contracts; IFRIC 13 Customer Loyalty Programs; IFRIC 15 Agreements for the Construction of Real Estate; IFRIC 18 Transfers of Assets from Customers; and SIC-31 Revenue - Barter Transactions Involving Advertising Services. |  | 01/01/2018
In April 2016, the IASB published an amendment to introduce clarifications with regard to identifying performance obligations in contracts with customers, to account for licensing involving intellectual property and for assessing principal versus agent considerations (i.e. Recording revenue on a gross basis versus the net amount it retains), among other aspects. These amendments are also effective as of January 1, 2018. The Company's revenue is mainly derived from its principal performance obligation to transfer its products under agreements in which the transfer of the control, risks and benefits of the property and the fulfillment of the Company’s performance obligations happen at the same time. The Company has carried out a detailed evaluation and executed a plan for the implementation of IFRS 15. As part of this process, the Company has analyzed the performance obligations underlying revenue recognition, such as the performance obligation to transport products to customers, in line with the terms and conditions previously established in contracts and there is no significant impact - the performance obligation has been satisfied. With regard to products invoiced with a deferred shipment date, the transfer of control has been assessed over and above the transfer of risks and benefits established in the previous standard and a prepayment is estimated in revenue recognition, without a significant impact. Other considerations were also assessed, such as rebates, discounts, guarantees, financing components and product personalization. Based on this analysis, the Company has concluded that these last items will not generate an impact nor are significant changes expected in the recording of revenue as a result of applying this new standard, except for the impact on disclosures. The Company has established the procedures and controls for beginning to apply IFRS 15 as of January 1, 2018. It intends to recognize the cumulative effect of applying IFRS 15 as an adjustment to the opening balance of equity as of that date, without making adjustments to the comparative information for prior periods. |  | 01/01/2018

IFRS 16 “Leases” – Published in January 2016 establishes the principle for recognizing, measuring, presenting and disclosing leases. IFRS 16 replaces IAS 17 and introduces a single lessee accounting model, requiring lessees to recognize assets and liabilities for all leases with a lease term of more than 12 months unless the underlying asset has a low value. IFRS 16 applies to annual reporting periods beginning on or after January 1, 2019. Earlier application is permitted for entities that apply IFRS 15 before the initial application date of IFRS 16. |  | 01/01/2019
IFRS 17 “Insurance Contracts”. Published in May 2017, this replaces IFRS 4. IFRS 17 will mainly change the accounting for those entities that issue insurance contacts and investment contracts with discretionary participation features. IFRS 17 is effective for annual reporting periods beginning on or after January 1, 2021. Earlier application is permitted if both IFRS 15 Revenue from Contracts with Customers and IFRS 9 Financial Instruments have also been applied. |  | 01/01/2021
IFRIC 22 “Foreign Currency Transactions and Advance Consideration”. Published in December 2016. This Interpretation applies to a foreign currency transaction (or part of one) if an entity recognizes a non-financial asset or non-financial liability arising from the payment or receipt of an advance consideration prior to the entity recognizing the related asset, expense or income (or the applicable portion thereof). The interpretation provides a guideline for the transaction date to be used for both single payments/receipts and situations when there are multiple payments/receipts. Its objective is to reduce diversity in practice. |  | 01/01/2018

IFRIC 23 “Uncertainty over Income Tax Treatments”. Published in June 2016. This interpretation clarifies how to apply the recognition and measurement requirements in IAS 12, when there is uncertainty over income tax treatments. |  | 01/01/2019
Amendment to IFRS 15 “Revenue from Contracts with Customers”. Published in April 2016. The amendment provides clarifications with regard to identifying performance obligations in contracts with customers, accounting for licensing involving intellectual property and assessing principal versus agent considerations (i.e. recording revenue on a gross basis versus the net amount it retains). It includes new and modified illustrative examples as a guide, along with practical examples related to the transition to the new standard on revenue. |  | 01/01/2018
Amendment to IAS 28 “Investments in Associates and Joint Ventures” in regard to measuring an associate or joint venture at fair value. Published in December 2016. |  | 01/01/2018
Amendment to IFRS 9 “Financial Instruments”. Published in October 2017. The amendment permits more assets to be measured at amortized cost than under the previous version of IFRS 9, in particular some prepayable financial assets with negative compensation. The assets affected, which include some loans and debt securities, would otherwise have been measured at fair value through profit and loss (FVTPL). For them to qualify for amortized cost measurement, the negative compensation must be "reasonable compensation for early termination of the contract”. |  | 01/01/2019
Amendment to IAS 28 “Investments in Associates and Joint Ventures” Published in October 2017. This amendment clarifies that companies should apply IFRS 9 to account for long-term interests in an associate or joint venture to which the equity method is not applied. The Board has published an example that illustrates how companies should apply the requirements of IFRS 9 and IAS 28 to long-term interests in an associate or joint venture. |  | 01/01/2019
Amendment to IFRS 3 “Business Combinations” Published in December 2017. The amendment clarifies that gaining control of a company that is a joint venture is a business combination that is achieved in stages. The acquirer must remeasure previously held interests in that business at fair value at the date of acquisition. |  | 01/01/2019
Amendment to IFRS 11 “Joint Arrangements” Published in December 2017. The amendment clarifies that when an entity obtains joint control of a business that is a joint operation, the entity does not remeasure previously held interests in that business. |  | 01/01/2019

Amendment to IAS 12 “Income Taxes”. Published in December 2017. This amendment clarifies that the income tax consequences of dividends on financial instruments classified as equity should be recognized when the past transactions or events that generated distributable profits were originally recognized. |  | 01/01/2019
Amendment to IAS 23 “Borrowing Costs”. Published in December 2017. This amendment clarifies that the borrowing costs of specific borrowings that remain outstanding after the related qualifying asset is ready for intended use or for sale will be considered as part of the general borrowing costs of the entity. |  | 01/01/2019

The following amendment was issued by the IASB and was originally scheduled to take effect in 2016. However, the organization has changed its position and the mandatory effective date is now to be determined.

Amendment to IFRS 10 “Consolidated Financial Statements” and IAS 28 “Investments in Associates and Joint Ventures”. Published in September 2014. These amendments address an inconsistency between the requirements in IFRS 10 and those in IAS 28 in dealing with the sale or contribution of assets between an investor and its associate or joint venture. The main consequence of the amendments is that a full gain or loss is recognized when a transaction involves a business (whether it is housed in a subsidiary or not). A partial gain or loss is recognized when a transaction involves assets that do not constitute a business, even if these assets are housed in a subsidiary. |  | Undetermined

Management believes the adoption of the standards, interpretations and amendments applicable as of January 1, 2018, will have no significant impact on the Company’s financial statements. For those standards to be applied as of 2019, the corresponding calculations and analysis will be performed during 2018.

| (a) | Subsidiaries

These are all those entities where Sociedad Química y Minera de Chile S.A. has control over directing their financial and operational policies. This is generally accompanied by a share of more than half of the voting rights. Subsidiaries apply the same accounting policies of their Parent.

To account for the acquisition, the Company uses the acquisition method. Under this method the acquisition cost is the fair value of assets delivered, equity securities issued, and liabilities incurred or assumed at the date of exchange. Identifiable assets acquired, and liabilities and contingencies assumed in a business combination are measured initially at fair value at the acquisition date. For each business combination, the Company will measure non-controlling interest of the acquiree either at fair value or as proportional share of net identifiable assets of the acquiree. For more information, please see Note 6.4

Notes to the Consolidated Financial Statements as of December 31, 2017

| Note 3 | Significant accounting policies

| 3.1 | Classification of balances as current and non-current

In the attached consolidated statement of financial position, balances are classified in consideration of their recovery (maturity) dates; i.e., those maturing within a period equal to or less than 12 months are classified as current counted from the closing date of the consolidated financial statements and those with maturity dates exceeding the aforementioned period are classified as non-current.

The exception to the foregoing relates to deferred taxes, which are classified as non-current, regardless of the maturity they have.

| 3.2 | Functional and presentation currency

The Company’s consolidated financial statements are presented in United States dollars (“U.S. dollars” or “US$”), which is the Company’s functional and presentation currency and is the currency of the main economic environment in which it operates.

Consequently, the term foreign currency is defined as any currency other than the U.S. dollar.

The consolidated financial statements are presented in thousands of United States dollars without decimals.

| 3.3 | Foreign currency translation

| (a) | Group entities:

The revenue, expenses, assets and liabilities of all entities that have a functional currency other than the presentation currency are converted to the presentation currency as follows:

| - | Assets and liabilities are converted at the closing exchange rate prevailing on the reporting date.

| - | Revenues and expenses of each profit or loss account are converted at monthly average exchange rates.

| - | All resulting foreign currency translation gains and losses are recognized as a separate component in translation reserves.

In consolidation, foreign currency differences arising from the translation of a net investment in foreign entities are recorded in equity (other reserves). At the date of disposal, such foreign currency translation differences are recognized in the statement of income as part of the gain or loss from the sale.

| F-28 |

| 3.3 | Foreign currency translation, continued

The main exchange rates and the adjustment unit used to translate monetary assets and liabilities, expressed in foreign currency at the end of each period in respect to U.S. dollars, are as follows:

(*) The Unidad de Fomento (UF) is an indexed monetary unit used in Chile, calculated based on the variation in the Consumer Price Index (CPI).

| (b) | Transactions and balances

Non-monetary transactions in currencies other than the functional currency (U.S. dollar) are translated to the respective functional currencies of Group entities at the exchange rate on the date of the transaction. Monetary assets and liabilities denominated in foreign currencies at the reporting date are retranslated to the functional currency at the exchange rate at that date. All differences are recorded in the statement of income except for all monetary items that provide an effective hedge for a net investment in a foreign operation. These items are recognized in other comprehensive income on the divestment, when they are recognized in the statement of income. Charges and credits attributable to foreign currency translation differences on those hedge monetary items are also recognized in other comprehensive income.

Non-monetary assets and liabilities that are measured at historical cost in a foreign currency are retranslated to the functional currency at the historical exchange rate of the transaction. Non-monetary items that are measured based on fair value in a foreign currency are translated using the exchange rate at the date on which the fair value is determined.

Notes to the Consolidated Financial Statements as of December 31, 2017

| Note 3 | Significant accounting policies (continued)

| 3.4 | Subsidiaries

SQM S.A. uses the level of control it has in subsidiaries as a basis to determine their share in the consolidated financial statements. This control consists of the Company’s ability to exercise power in the subsidiary, exposure, or right, to variable performance from its share in the investee and the ability to use its power on the investee to have an influence on the amount of the investor’s performance.

The Company prepares the consolidated financial statements using consistent accounting policies for the entire Group. The consolidation of a subsidiary commences when the Company has control over the subsidiary and stops when control ceases.

| 3.5 | Consolidated statement of cash flows

Cash equivalents correspond to highly-liquid short-term investments that are easily convertible into known amounts of cash. They are subject to insignificant risk of changes in their value and mature in less than three months from the date of acquisition of the instrument.

For the purposes of the statement of cash flows, cash and cash equivalents comprise cash and cash equivalents as defined above.

The statement of cash flows includes movements in cash performed during the year, determined using the direct method.

| 3.6 | Financial assets

Management determines the classification of its financial assets at the time of initial recognition, on the basis of the business model for the management of financial assets and the characteristics of contractual cash flows from the financial assets. In accordance with IAS 39, financial assets are measured initially at fair value plus transaction costs that may have been incurred and are directly attributable to the acquisition of the financial asset. Subsequently, financial assets are measured at amortized cost or fair value.

The Company assesses, at each reporting date, whether there is objective evidence that an asset or group of assets is impaired. An asset or group of financial assets is impaired if and only if there is evidence of impairment as a result of one or more events occurring after the initial recognition of the asset or group of assets. For the recognition of impairment, the loss event has to have an impact on the estimate of future cash flows from the asset or groups of financial assets.

| F-30 |

Notes to the Consolidated Financial Statements as of December 31, 2017

| Note 3 | Significant accounting policies (continued)

| 3.7 | Financial liabilities

Management determines the classification of its financial liabilities at the time of initial recognition. As established in IAS 39, financial liabilities at the time of initial recognition are measured at fair value, less transaction costs that may have been incurred and are directly attributable to the issue of the financial liability. Subsequently, these are measured at amortized cost using the effective interest method. Financial liabilities that have been initially recognized at fair value through profit or loss will be measured subsequently at fair value.

| 3.8 | Financial instruments at fair value through profit or loss

Management will irrevocably determine, at the time of initial recognition, the designation of a financial instrument at fair value through profit or loss. By doing so, this eliminates and/or significantly reduces the measurement or recognition inconsistency that would otherwise have arisen from the measurement of assets or liabilities or from the recognition of gains and losses from them on different bases.

| 3.9 | Financial instrument offsetting

The Company offsets an asset and liability if and only if it presently has a legally enforceable right of setting off the amounts recognized and has the intent of settling for the net amount of realizing the asset and settling the liability simultaneously.

| 3.10 | Reclassification of financial instruments

At such time when the Company changes its business model for managing financial assets, it will reclassify those financial assets affected by the new business model.

Financial liabilities could not be reclassified.

| 3.11 | Derivative and hedging financial instruments

Derivatives are recognized initially at fair value as of the date on which the derivatives contract is signed and, they are subsequently assessed at fair value. The method for recognizing the resulting gain or loss depends on whether the derivative has been designated as an accounting hedge instrument and, if so, it depends on the type of hedging, which may be as follows:

| a) | Fair value hedge of assets and liabilities recognized (fair value hedges);

| b) | Hedging of a single risk associated with an asset or liability recognized or a highly probable forecast transaction (cash flow hedge).

At the beginning of the transaction, the Company documents the relationship that exists between hedging instruments and those items hedged, as well as their objectives for risk management purposes and the strategy to conduct different hedging operations.

| F-31 |

Notes to the Consolidated Financial Statements as of December 31, 2017

| Note 3 | Significant accounting policies (continued)

| 3.11 | Derivative and hedging financial instruments, continued

The Company also documents its evaluation both at the beginning and at the end of each period if the derivatives used in hedging transactions are highly effective to offset changes in the fair value or in cash flows of hedged items.

The fair value of derivative instruments used for hedging purposes is shown in Note 10.3 (hedging assets and liabilities). Changes in the cash flow hedge reserve are classified as a non-current asset or liability if the remaining expiration period of the hedged item is more than 12 months, and as a current asset or liability if the remaining expiration period of the entry is less than 12 months.

Derivatives that are not designated or do not qualify as hedging derivatives are classified as current assets or liabilities, and changes in the fair value are directly recognized through profit or loss.

| a) | Fair value hedge

Changes in the fair value of derivatives that are designated and qualify as fair value hedges are recorded in profit or loss, together with any changes in the fair value of the hedged asset or liability that are attributable to the hedged risk. The gain or loss relating to the effective portion of interest rate swaps that hedge fixed rate borrowings is recognized in profit or loss within finance costs, together with changes in the fair value of the hedged fixed rate borrowings attributable to interest rate risk. The gain or loss relating to the ineffective portion is recognized in profit or loss within other income or other expenses. If the hedge no longer meets the criteria for hedge accounting, the adjustment to the carrying amount of a hedged item for which the effective interest method is used is amortized to profit or loss over the period to maturity using a recalculated effective interest rate.

| b) | Cash flow hedges

The effective portion of gains or losses from the hedge instrument is initially recognized with a debit or credit to other comprehensive income, whereas any ineffective portion is immediately recognized with a debit or credit to profit or loss, as applicable.

Amounts taken to equity are transferred to profit or loss when the hedged transaction affects profit or loss, as when the hedged interest income or expense is recognized when a projected sale occurs. When the hedged entry is the cost of a non-financial asset or liability, amounts taken to other reserves are transferred to the initial carrying value of the non-financial asset or liability.

If the expected firm transaction or commitment is no longer expected to occur, the amounts previously recognized in equity are transferred to profit or loss. If a hedge instrument expires, is sold, finished, or exercised without any replacement, or if a rollover is performed or if its designation as hedging is revoked, the amounts previously recognized in other reserves are maintained in equity until the expected firm transaction or commitment occurs.

| F-32 |

Notes to the Consolidated Financial Statements as of December 31, 2017

| Note 3 | Significant accounting policies (continued)

| 3.12 | Available for sale financial assets

Available for sale financial assets are non-derivative financial assets, which have been designated as available for sale and are not classified in any of the previous categories of financial instruments. Available for sale financial instruments are initially recognized at fair value plus any directly attributable transaction costs.

Subsequent to initial recognition, they are recognized at fair value and changes other than impairment losses are recognized in other comprehensive income and presented in equity in the fair value reserve. If an investment is derecognized, the accumulated gain or loss is reclassified to profit or loss.

| 3.13 | Derecognition of financial instruments

In accordance with IAS 39, the Company derecognizes a financial asset when the contractual rights to the cash flows from the asset expire, or it transfers the rights to receive the contractual cash flows in a transaction in which substantially all the risks and rewards of ownership of the financial asset are transferred; and the control of the financial assets has not been retained.

The Company derecognizes a financial liability when its contractual obligations or a part of these are discharged, paid to the creditor or legally extinguished.

| 3.14 | Derivative financial instruments

The Company maintains derivative financial instruments to hedge its exposure to foreign currencies. Derivative financial instruments are recognized initially at fair value; attributable transact ion costs are recognized when incurred. Subsequent to initial recognition, any changes in the fair value of such derivatives are recognized in profit or loss as part of gains and losses.

The Company permanently assesses the existence of embedded derivatives, both in its contracts and financial instruments. As of December 31, 2017, and December 31, 2016, there were no embedded derivatives.

| 3.15 | Fair value initial measurements

From the initial recognition, the Company measures its assets and liabilities at fair value plus or minus transaction costs incurred that are directly attributable to the acquisition of a financial asset or issuance of a financial liability.

| Note 3 | Significant accounting policies (continued)

| 3.16 | Deferred acquisition costs from insurance contracts

Acquisition costs from insurance contracts are classified as prepayments and correspond to insurance contracts in force, recognized using the straight-line method and on an accrual basis, and are recognized under other non-financial assets.

| (a) | Lease - Finance lease

Leases are classified as finance leases when the Company holds substantially all the risks and rewards derived from the ownership of the asset. Finance leases are capitalized at the beginning of the lease, at the lower of the fair value of the leased asset or the present value of minimum lease payments.

Each lease payment is distributed between the liability and the interest expenses to obtain ongoing interest on the pending balance of debt. The respective lease obligations, net of interest expense, are included in other non-current liabilities. The interest element of finance cost is debited in the consolidated statement of income during the lease period so that a regular ongoing interest rate is obtained on the remaining balance of the liability for each year.

| (b) | Lease - Operating lease

Leases in which the lesser maintains a significant part of the risks and rewards derived from the ownership are classified as operating leases. Operating lease payments (net of any incentive received from the lesser) are debited to the statement of income or capitalized (as applicable) on a straight-line basis over the lease period.

| 3.17 | Trade and other receivables

Trade and other receivables relate to non-derivative financial assets with fixed and determinable payments and are not quoted in any active market. These arise from sales operations involving the products and/or services, of which the Company commercializes directly to its customers.

These assets are initially recognized at their fair value and subsequently at amortized cost according to the effective interest rate method, less a provision for impairment loss. An allowance for impairment loss is established for trade receivables when there is objective evidence that the Company will not be able to collect all the amounts which are owed to it, according to the original terms of receivables.

Implicit interest in installment sales is recognized as interest income when interest is accrued over the term of the operation.

Notes to the Consolidated Financial Statements as of December 31, 2017

| Note 3 | Significant accounting policies (continued)

| 3.18 | Inventory measurement

The Company measures inventories at the lower of production cost and net realizable value. The cost price of finished products and work in progress includes the direct cost of materials and, when applicable, labor costs, the depreciation of goods that are involved in the production process, the indirect costs incurred in transforming raw materials into finished products, and general expenses incurred in carrying inventories to their current location and conditions. The method used to determine the cost of inventories is the weighted average monthly cost and the average cost of warehouse storage.

Commercial discounts, rebates obtained, and other similar entries are deducted when determining the acquisition price.

The net realizable value represents the estimated selling price, less all the estimated costs of completion and the estimated costs necessary to make the sale.

The Company conducts an evaluation of the net realizable value of inventories at the end of each year, recording a debit to profit or loss when the inventory costs exceed the realizable value. This estimate is made for all the finished and intermediate products in the Company’s inventory. The valuation of obsolete, impaired or slow-moving products relates to their estimated net realizable value.

The provisions for uncertainties in the technical specifications for the Company’s stocks of finished goods and work in progress have been made based on a technical study which covers the different variables that affect products in stock (such as density and humidity). This study is updated periodically to include new measurement technologies and the results from previous financial periods.

Inventories of raw materials, supplies, materials and parts are recorded at the lower of acquisition cost or market value. The acquisition cost is calculated according to the average acquisition price method. Nonetheless, an estimate is made for each financial period of the potential lower value relating to the proportion of inventory that consists of obsolete, defective or slow-moving materials. This provision reduces the value of the Company’s raw materials, supplies, materials and parts.

| 3.19 | Investments in associates and joint ventures

Interests in companies over which joint control is exercised (joint venture) or where an entity has a significant influence (associates) are recognized using the equity method of accounting. Significant influence is presumed to exist when interest greater than 20% is held in the capital of an investee.

Under this method, the investment is recognized in the statement of financial position at cost plus changes, subsequent to the acquisition, and considering the proportional share in the equity of the associate. For such purposes, the interest percentage in the ownership of the associate is used. The associated goodwill acquired is included in the carrying amount of the investee and is not amortized. The debit or credit to profit or loss reflects the proportional share in the profit or loss of the associate.

| F-35 |

Notes to the Consolidated Financial Statements as of December 31, 2017

| Note 3 | Significant accounting policies (continued)

| 3.19 | Investments in associates and joint ventures, continued

Unrealized gains for transactions with affiliates or associates are eliminated according to the Company’s interest percentage in such entities. Unrealized losses are also eliminated, except if the transaction provides evidence of impairment loss of the transferred asset.

Changes in the equity of associates are recognized on a proportional basis with a charge or credit to “Other reserves” and classified according to their origin.

Reporting dates of the associate, the Company and related policies are similar for equivalent transactions and events under similar circumstances.

In the event that the significant influence is lost or the investment is sold or is held as available for sale, the equity method is discontinued, suspending the recognition of the proportional share of profit or loss.

If the resulting amount according to the equity method is negative, the share of profit or loss is reflected as zero in the consolidated financial statements, unless a commitment exists by the Company to reinstate the Company’s equity position, in which case the related provision for risks and expenses is recorded.

Dividends received by these companies are recorded by reducing the equity value, and the proportional share of profit or loss recognized according to the equity share are included in the consolidated profit or loss accounts in the caption “Equity share of profit (loss) of associates and joint ventures that are accounted for using the equity method of accounting”.

| 3.20 | Transactions with non-controlling interests

Non-controlling interests are recorded in the consolidated statement of financial position within equity, but separate from equity attributable to the owners of the Parent.

| 3.21 | Related party transactions

Transactions between the Company and its subsidiaries are part of the Company’s normal operations within its scope of business activities. Conditions for such transactions are those normally effective for those types of operations with regard to terms and market prices. These transactions have been eliminated in consolidation. The expiration conditions vary according to the originating transaction.

| 3.22 | Property, plant and equipment

The assets tangible property, plant and equipment assets are stated at acquisition cost, net of the related accumulated depreciation, amortization and impairment losses that they might have experienced.

In addition to the price paid for the acquisition of tangible property, plant and equipment, the Company has considered the following concepts as part of the acquisition cost, as applicable:

1. Accrued interest expenses during the construction period that are directly attributable to the acquisition, construction or production of qualifying assets, which are those that require a substantial period prior to being ready for use. The interest rate used is that related to the project’s specific financing or, should this not exist, the average financing rate of the investor company.

2. The future costs that the Company will have to experience, related to the closure of its facilities at the end of their useful life, are included at the present value of disbursements expected to be required to settle the obligation.

Construction-in-progress is transferred to property, plant and equipment in operation once the assets are available for use and the related depreciation and amortization begins on that date.

Extension, modernization or improvement costs that represent an increase in productivity, ability or efficiency or an extension of the useful lives of property, plant and equipment are capitalized as a higher cost of the related assets. All the remaining maintenance, preservation and repair expenses are charged to expense as they are incurred.

The replacement of full assets, which increase the asset’s useful life or its economic capacity, are recorded as a higher value of property, plant and equipment with the related derecognition of replaced or renewed elements.

Gains or losses which are generated from the sale or disposal of property, plant and equipment are recognized as income (or loss) in the period, and calculated as the difference between the asset’s sales value and its net carrying value.

Costs derived from the daily maintenance of property, plant and equipment are recognized when incurred.

| F-37 |

Notes to the Consolidated Financial Statements as of December 31, 2017

| Note 3 | Significant accounting policies (continued)

| 3.23 | Depreciation of property, plant and equipment

Property, plant and equipment are depreciated through the straight-line distribution of cost over the estimated technical useful life of the asset, which is the period in which the Company expects to use the asset. When components of one item of property, plant and equipment have different useful lives, they are recorded as separate assets. Useful lives are reviewed on an annual basis.

In the case of mobile equipment, depreciation is performed depending on the hours of operation

The useful lives used for the depreciation and amortization of assets included in property, plant and equipment in years are presented below.

Classes of property, plant and equipment |  | Minimum life or rate (years) |  |  | Maximum life or rate (years) |  |  | life or average rate in years |
Mining assets |  |  | 3 |  |  |  | 10 |  |  |  | 7 |

| 3.24 | Goodwill

Goodwill acquired represents the excess in acquisition cost on the fair value of the Company's ownership of the net identifiable assets of the subsidiary on the acquisition date. Goodwill acquired related to the acquisition of subsidiaries is included in goodwill, which is subject to impairment tests annually or more frequently if events or changes in circumstances indicate that it might be impaired, and is stated at cost less accumulated impairment losses. Gains and losses related to the sale of an entity include the carrying value of goodwill related to the entity sold.

This intangible asset is assigned to cash-generating units with the purpose of testing impairment losses. It is allocated based on cash-generating units expected to obtain benefits from the business combination from which the aforementioned goodwill acquired arose.

| F-38 |

Notes to the Consolidated Financial Statements as of December 31, 2017

| Note 3 | Significant accounting policies (continued)

| 3.25 | Intangible assets other than goodwill

Intangible assets mainly relate to water rights, rights issues, electric line easement expenses and software license and development expenses.

| (a) | Water rights

Water rights acquired by the Company relate to water from natural sources and are recorded at acquisition cost. Given that these assets represent legal rights granted in perpetuity to the Company, they are not amortized, but are subject to annual impairment tests.

| (b) | Rights of way for electric lines

As required for the operation of industrial plants, the Company has paid rights of way in order to install wires for the different electric lines on third party land. These rights are presented under intangible assets. Amounts paid are capitalized at the date of the agreement and charged to the statement of income, according to the life of the right of way.

| (c) | Computer software

Licenses for IT programs acquired are capitalized based on their acquisition and customization costs. These costs are amortized over their estimated useful lives.

Expenses related to the development or maintenance of IT programs are recognized as an expense as and when incurred. Costs directly related to the production of unique and identifiable IT programs controlled by the Group, and which will probably generate economic benefits that are higher than its costs during more than a year, are recognized as intangible assets. Direct costs include the expenses of employees who develop information technology software and general expenses in accordance with corporate charges received.

The costs of development for IT programs recognized as assets are amortized over their estimated useful lives.

| (d) | Mining property and concession rights

The Company holds mining property and concession rights from the Chilean Government. Property rights are usually obtained at no initial cost (other than the payment of mining patents and minor recording expenses) and once the rights on these concessions have been obtained, they are retained by the Company while annual patents are paid. Such patents, which are paid annually, are recorded as prepaid assets and amortized over the following twelve months. Amounts attributable to mining concessions acquired from third parties that are not from the Chilean Government are recorded at acquisition cost within intangible assets.

No impairment of intangible assets exists as of December 31, 2017 and December 31, 2016.

| F-39 |

Notes to the Consolidated Financial Statements as of December 31, 2017

| Note 3 | Significant accounting policies (continued)

| 3.26 | Research and development expenses

Research and development expenses are charged to profit or loss in the period in which the expenditure was incurred.

| 3.27 | Prospecting expenses

The Company has mining property and concession rights from the Chilean Government and others that it has acquired from third parties other than the Chilean Government, destined to the exploitation of caliche ore and saltpeter deposits and also the exploration of these types of deposits.

Upon obtaining these rights, the Company initially records disbursements directly associated with the exploration and evaluation of deposits (associated with small deposits with trading feasibility) as asset at cost. Such disbursements include the following concepts:

| - | Disbursements for geological reconnaissance evaluation

| - | Disbursements for drilling

| - | Disbursements for drilling work and sampling

| - | Disbursements for activities related to technical assessment and trading feasibility of drilling work

| - | And any disbursement directly related to specific projects where its objective is finding mining resources.

Subsequently, the Company distinguishes exploration and evaluation projects according to the economic feasibility of the mineral extracted in the area or exploration, among those that finally will deliver future benefits to the Company (profitable projects) and those projects that are unlikely to bring profit to the Company in the future (i.e., when the ore grade at the site is low and its exploitation is not economically profitable).

If technical studies determine that the ore grade is not economically suitable for exploitation, the asset is directly expensed. Otherwise, it is held in the caption “other non-current assets”, reclassifying the portion related to the area to be exploited in the year in the caption inventories and such amount is amortized as production cost on the basis of estimated tons to be extracted.

The technical reasons for this classification correspond to the fact that this is an identifiable non-monetary asset that is owned to be used in the production of our processes as a main raw material.

For this reason and because our disbursements correspond to reserves that have proved to be financially feasible and used as a principal raw material in our production processes, these are presented as inventories that will be exploited within the commercial year and the remainder as development expenses for small deposits and prospecting expenses in the caption “other non-current assets”.

| 3.28 | Impairment of non-financial assets

Assets subject to depreciation and amortization are also subject to impairment testing, provided that an event or change in the circumstances indicates that the amounts in the accounting records may not be recoverable. An impairment loss is recognized for the excess of the book value of the asset over its recoverable amount.

The recoverable amount of an asset is the higher between the fair value of an asset or cash generating unit (“CGU”) less costs of sales and its value in use, and is determined for an individual asset unless the asset does not generate any cash inflows that are clearly independent from other assets or groups of assets.

When the carrying value of an asset exceeds its recoverable amount, the asset is considered an impaired asset and is reduced to its net recoverable amount.

In evaluating value in use, estimated future cash flows are discounted using a pre-tax discount rate that reflects current market assessment, the value of money over time and the specific asset risks.

To determine the fair value less costs to sell, an appropriate valuation model is used.

Impairment losses from continuing operations are recognized with a debit to profit or loss in the categories of expenses associated with the impaired asset function, except for properties reevaluated previously where the revaluation was taken to equity.

For assets other than acquired goodwill, an annual evaluation is carried out to determine whether any previously recognized impairment losses have already decreased or ceased to exist. If this should be the case, the recoverable amount is estimated. A previously recognized impairment loss is only reversed if there have been changes in the estimates used to determine the asset’s recoverable amount since the last time an impairment loss was recognized. If this is the case, the carrying value of the asset is increased to its recoverable amount. This increased amount cannot exceed the carrying value that would have been determined, net of depreciation, if an asset impairment loss had not been recognized in prior years. This reversal is recognized with a credit to profit or loss.

| 3.29 | Minimum dividend

As required by the Shareholders’ Corporations Act, unless decided otherwise by a unanimous vote by the shareholders of subscribed and paid shares, a public company must distribute dividends as agreed by the shareholders at the General Shareholders’ Meeting held each year. This must entail a minimum of 30% of its profits, except when the Company records unabsorbed losses from prior years. However, the Company has set a policy to distribute 50% of its profits for the year, unless decided otherwise by a unanimous vote by the shareholders at the General Shareholders´ meeting held each year.

At an extraordinary meeting held on April 11, 2017, the Company’s Board of Directors made a recommendation for discussion at the Ordinary Shareholders’ Meeting (the Meeting), which was held on April 28, 2017, that the Company should distribute and pay dividends based on 100% of the Company’s net profit for distribution for the financial year 2016. This recommendation was accepted by the Meeting.

| 3.29 | Minimum dividend, continued

For 2017, the Company has defined the following dividend policy: (a) To distribute and pay a dividend to the respective shareholders, a percentage of the profits to be determined as follows:

(i) 100% of the profit for 2017 if all the following financial parameters are met: (a) that the total of cash and cash equivalents and other current financial assets (“Cash”) divided by the addition of other current financial liabilities (the “Short-term Financial Liabilities”) is equal to or more than 2.5 times, and (b) the total of current liabilities and non-current liabilities (“Total Liabilities”) divided by total equity (“Equity”) is equal to or less than 1.1 times.

(ii) 80% of profit for 2017 if all the following financial parameters are met: (a) that Cash divided by Short-term Financial Liabilities is equal to or more than 2.0 times, and (b) Total Liabilities divided by Total Equity is equal to or less than 1.2 times.

(iii) 60% of profit for 2017 if all the following financial parameters are met: (a) that Cash divided by Short-term Financial Liabilities is equal to or more than 1.5 times, and (b) Total Liabilities divided by Total Equity is equal to or less than 1.3 times. Should none of these parameters be met, the Company will distribute and pay as dividend 50% of the profit for 2017 to the respective shareholders.

| 3.30 | Earnings per share

The basic earnings per share amounts are calculated by dividing the profit for the year attributable to the ordinary owners of the parent by the weighted average number of ordinary shares outstanding during the year.

The Company has not conducted any type of operation of potential dilutive effect that would entail the disclosure of diluted earnings per share.

| 3.31 | Trade and other payables

Trade and other payables are measured at fair value plus all costs associated with the transaction. Subsequently, these are carried out at amortized cost using the effective interest rate method.

| 3.32 | Interest-bearing borrowings

At initial recognition, interest-bearing borrowings are measured at fair value net of transaction costs incurred. Subsequently, they are measured at amortized cost using the effective interest rate method. Amortized cost is calculated considering any premium or discount from the acquisition and includes costs of transactions which are an integral part of the effective interest rate.

These are recorded as non-current when their expiration period exceeds twelve months and as current when the term is lower than such term. Interest expense is calculated in the year in which it is accrued following a financial criterion.

| F-42 |

Notes to the Consolidated Financial Statements as of December 31, 2017

| Note 3 | Significant accounting policies (continued)

| 3.33 | Other provisions

Provisions are recognized when:

| - | The Company has a present obligation or constructive obligation as the result of a past event.

| - | It is more likely than not that certain resources must be used, including benefits, to settle the obligation.

| - | A reliable estimate can be made of the amount of the obligation.

In the event that the provision or a portion of it is reimbursed, the reimbursement is recognized as a separate asset solely if there is certainty of income.

In the consolidated statement of income, the expense for any provision is presented net of any reimbursement.

Should the effect of the value of money over time be significant, provisions are discounted using a discount rate before tax that reflects the liability’s specific risks. When a discount rate is used, the increase in the provision over time is recognized as a finance cost.

The Company’s policy is to maintain provisions to cover risks and expenses based on a better estimate to deal with possible or certain and quantifiable responsibilities from current litigation, compensations or obligations, pending expenses for which the amount has not yet been determined, collaterals and other similar guarantees for which the Company is responsible. These are recorded at the time the responsibility or the obligation that determines the compensation or payment is generated.

| 3.34 | Obligations related to employee termination benefits and pension commitments

Obligations towards the Company’s employees comply with the provisions of the collective bargaining agreements in force, which are formalized through collective employment agreements and individual employment contracts, except for the United States, which is regulated in accordance with employment plans in force up to 2002. (See more details in Note 15.4)

These obligations are valued using actuarial calculations, according to the projected unit credit method which considers such assumptions as the mortality rate, employee turnover, interest rates, retirement dates, effects related to increases in employees’ salaries, as well as the effects on variations in services derived from variations in the inflation rate. The criteria in force contained in the revised IAS 19 are also taken into account.

Actuarial gains and losses that may be generated by variations in defined, pre-established obligations are directly recorded in other comprehensive income.

Actuarial losses and gains have their origin in departures between the estimate and the actual behavior of actuarial assumptions or in the reformulation of established actuarial assumptions.

The discount rate used by the Company for calculating the obligation was 5.111% and 4.522% for the periods ended December 31, 2017 and December 31, 2016, respectively.

The Company’s subsidiary SQM North America has established pension plans for its retired employees that are calculated by measuring the projected obligation using a net salary progressive rate net of adjustments for inflation, mortality and turnover assumptions, deducting the resulting amounts at present value using a 3.75% interest rate for 2017 and 4.5% for 2016. The net balance of this obligation is presented under the non-current provisions for employee benefits (refer to Note 15.4).

| 3.35 | Compensation plans

Compensation plans implemented through benefits provided in share-based payments settled in cash are recognized in the financial statements at their fair value, in accordance with International Financial Reporting Standards No. 2 "Share-based Payments.” Changes in the fair value of options granted are recognized with a charge to payroll on a straight-line basis during the period between the date on which these options are granted and the payment date (see Note 16).

| 3.36 | Revenue recognition

Revenue includes the fair value of considerations received or receivable for the sale of goods and services during the performance of the Company's activities. Revenue is presented net of value added tax, estimated returns, rebates and discounts and after the elimination of sales among subsidiaries.

Revenue is recognized when its amount can be stated reliably, it is probable that the future economic rewards will flow to the entity and it meets the specific conditions for each type of activity-related revenue, as follows:

| (a) | Sale of goods

The sale of goods is recognized when the Company has delivered products to the customer, and there is no obligation pending compliance that could affect the acceptance of products by the customer. The delivery does not occur until products have been shipped to the customer or confirmed as received by the customer, and the related risks of obsolescence and loss have been transferred to the customer and the customer has accepted the products in accordance with the conditions established in the sale, when the acceptance period has ended, or when there is objective evidence that those criteria required for acceptance have been met.

Sales are recognized in consideration of the price set in the sales agreement, net of volume discounts and estimated returns at the date of the sale. Volume discounts are evaluated in consideration of annual foreseen purchases and in accordance with the criteria defined in agreements.

| (b) | Sale of services

Revenue associated with the rendering of services is recognized considering the degree of completion of the service as of the date of presentation of the consolidated classified statement of financial position, provided that the result from the transaction can be estimated reliably.

| (c) | Interest income

Interest income is recognized when interest is accrued in consideration of the principal pending payment using the effective interest rate method.

| (d) | Income from dividends

Income from dividends is recognized when the right to receive the payment is established.

| 3.37 | Finance income and finance costs

Finance income is mainly composed of interest income in financial instruments such as term deposits and mutual fund deposits. Interest income is recognized in profit or loss at amortized cost, using the effective interest rate method.

Finance costs are mainly composed of interest on bank borrowing expenses, interest on bonds issued and interest capitalized for borrowing costs for the acquisition, construction or production or qualifying assets.

Borrowing costs and bonds issued are recognized in profit or loss using the effective interest rate method.

| F-45 |

Notes to the Consolidated Financial Statements as of December 31, 2017

| Note 3 | Significant accounting policies (continued)

| 3.37 | Finance income and finance costs, continued

For finance costs accrued during the construction period that are directly attributable to the acquisition, construction or production of qualifying assets, the effective interest rate related to the project’s specific financing is used. If none exists, the average financing rate of the subsidiary making the investment is utilized. Borrowing and financing costs that are directly attributable to the acquisition, construction or production of an asset are capitalized as part of that asset’s cost.

| 3.38 | Income tax and deferred taxes

Corporate income tax for the year is determined as the sum of current taxes from the different consolidated companies.

Current taxes are based on the application of the various types of taxes attributable to taxable income for the year.

Differences between the book value of assets and liabilities and their tax basis generate the balance of deferred tax assets or liabilities, which are calculated using the tax rates expected to be applicable when the assets and liabilities are realized.

In conformity with current Chilean tax regulations, the provision for corporate income tax and taxes on mining activity is recognized on an accrual basis, presenting the net balances of accumulated monthly tax provisional payments for the fiscal period and associated credits. The balances of these accounts are presented in current income taxes recoverable or current taxes payable, as applicable.

Tax on companies and variations in deferred tax assets or liabilities that are not the result of business combinations are recorded in the statement of income accounts or equity accounts in the consolidated statement of financial position, considering the origin of the gains or losses which have generated them.

At each reporting period, the carrying amount of deferred tax assets has been reviewed and reduced to the extent where there will not be sufficient taxable income to allow the recovery of all or a portion of the deferred tax assets. Likewise, as of the date of the consolidated financial statements, deferred tax assets that are not recognized were evaluated and not recognized as it was more likely than not that future taxable income will allow for recovery of the deferred tax asset.

With respect to deductible temporary differences associated with investments in subsidiaries, associated companies and interest in joint ventures, deferred tax assets are recognized solely provided that it is more likely than not that the temporary differences will be reversed in the near future and that there will be taxable income with which they may be used.

The deferred income tax related to entries directly recognized in equity is recognized with an effect on equity and not with an effect on profit or loss.

Deferred tax assets and liabilities are offset if there is a legally receivable right of offsetting tax assets against tax liabilities and the deferred tax is related to the same tax entity and authority.

| 3.39 | Segment reporting

IFRS 8 requires that companies adopt a “management approach” to disclose information on the operations generated by its operating segments. In general, this is the information that management uses internally for the evaluation of segment performance and making the decision on how to allocate resources for this purpose.

An operating segment is a group of assets and operations responsible for providing products or services subject to risks and performance that are different from those of other business segments. A geographical segment is responsible for providing products or services in a given economic environment subject to risks and performance that are different from those of other segments operating in other economic environments.

For assets and liabilities, the allocation to each segment is not possible given that these are associated with more than one segment, except for depreciation, amortization and impairment of assets, which are directly allocated to the applicable segments, in accordance with the criteria established in the costing process for product inventories.

The following operating segments have been identified by the Company:

| - | Specialty plant nutrients

| - | Industrial chemicals

| - | Iodine and derivatives

| - | Lithium and derivatives

| - | Potassium

| - | Other products and services

| 3.40 | Responsibility for Information and Estimates Made

The Management of Sociedad Química y Minera de Chile S.A. and its subsidiaries is responsible for the information contained in these consolidated financial statements, which expressly indicate that all the principles and criteria included in IFRS, as issued by the International Accounting Standards Board (IASB), have been applied in full.

In preparing the consolidated financial statements of Sociedad Química y Minera de Chile S.A. and its subsidiaries, Management has made judgments and estimates to quantify certain assets, liabilities, revenues, expenses and commitments included therein. Basically, these estimates refer to:

| - | The useful lives of property, plant and equipment, and intangible assets and their residual value Estimated useful lives are determined based on current facts and past experience, and take into consideration the anticipated physical life of the asset, the potential for technological obsolescence, and regulations. See notes 3.22, 13 and 14.

| - | Impairment losses of certain assets - Assets, including property, plant and equipment, exploration assets, goodwill and intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that their carrying amounts exceed their recoverable amounts. If an impairment assessment is required, the assessment of fair value often requires estimates and assumptions such as discount rates, exchange rates, commodity prices, future capital requirements and future operating performance. Changes in such estimates could impact the recoverable values of these assets. Estimates are reviewed regularly by management. See notes 13 and 14.

| - | Assumptions used in calculating the actuarial amount of pension-related and severance indemnity payment benefit commitments. See Note 15.

| - | Contingencies – The amount recognized as a provision, including legal, contractual, constructive and other exposures or obligations, is the best estimate of the consideration required to settle the related liability, including any related interest charges, taking into account the risks and uncertainties surrounding the obligation. In addition, contingencies will only be resolved when one or more future events occur or fail to occur. Therefore, the assessment of contingencies inherently involves the exercise of significant judgment and estimates of the outcome of future events. The Company assesses its liabilities and contingencies based upon the best information available, relevant tax laws and other appropriate requirements. See notes 18 and 19.

| - | Provisions on the basis of technical studies that cover the different variables affecting products in stock (density and moisture, among others), and related allowance.

| - | Obsolescence to ensure that the carrying value of inventory is not in excess of the net realizable Inventory valuation requires judgment to determine obsolescence and estimates of provisions for value. See note 8.

Despite the fact that these estimates have been made on the basis of the best information available on the date of preparation of these consolidated financial statements, certain events may occur in the future and oblige their amendment (upwards or downwards) over the next few years, which would be made prospectively, recognizing the effects of the change in estimates in the related future consolidated financial statements.

| Note 3 | Significant accounting policies (continued)

| 3.41 | Environment

In general, the Company follows the criteria of considering amounts used in environmental protection and improvement as environmental expenses. However, the cost of facilities, machinery and equipment used for the same purpose are considered property, plant and equipment, as the case may be.

| Note 4 | Financial risk management

| 4.1 | Financial risk management policy

The Company’s financial risk management policy is focused on safeguarding the stability and sustainability of Sociedad Química y Minera de Chile S.A. and its subsidiaries with regard to all such relevant financial uncertainty components.

The Company’s operations are subject to certain financial risk factors that may affect its financial position or results. The most significant risk exposures are market risk, liquidity risk, currency risk, doubtful accounts risk, and interest rate risk, among others.

There could also be additional risks, which are either unknown or known but not currently deemed to be significant, which could also affect the Company’s business operations, its business, financial position, or profit or loss.

The financial risk management structure includes identifying, determining, analyzing, quantifying, measuring and controlling these events. Management and, in particular, Finance Management, is responsible for constantly assessing the financial risk. The Company uses derivatives to hedge a significant portion of those risks.

| F-49 |

Notes to the Consolidated Financial Statements as of December 31, 2017

| Note 4 | Financial risk management, continued

| 4.2 | Risk factors

| 4.2.1 | Market risk

Market risk refers to the uncertainty associated with fluctuations in market variables affecting the Company’s assets and liabilities, including:

| a) | Price risk: The Company’s product prices are affected by the fluctuations in international prices of fertilizers and chemicals, as well as changes in production capacities or market demand, all of which might affect the Company’s business, financial position and results of operations.

| b) | Commodity price risk: The Company is exposed to changes in commodity prices and energy which may have an impact on its production costs that may cause unstable results.

At present, the SQM Group incurs an annual expenditure of approximately US$117 million associated with fuel, gas, energy and equivalents, of which US$77 million is related to direct electricity consumption. A change of 10% in the prices of energy required for the Company’s operations may involve costs of approximately US$12 million in short-term movements.

The markets in which the Company operates are unpredictable, exposed to significant fluctuations in supply and demand, and high price volatility. Additionally, the supply of certain fertilizers or chemicals, including certain products in which the Company trades vary, mainly depending on the production of top producers and their related business strategies. Accordingly, the Company cannot forecast with certainty changes in demand, responses from competitors or fluctuations in the final price of its products. These factors can lead to significant impacts on the Company’s product sales volumes, financial position and share price.

| c) | Quality standards: In the markets in which we operate, customers might impose quality standards on our products and/or governments could enact more stringent standards for the distribution and/or use of our products. Consequently, we might not be able to sell our products if we are not able to meet those new standards. In addition, our production costs might increase to meet such new standards. Not being able to sell our products in one or more markets or to key customers might significantly affect our business, financial position or the results of our operations.

| F-50 |

Notes to the Consolidated Financial Statements as of December 31, 2017

| Note 4 | Financial risk management, continued

| 4.2.2 | Credit risk

A contraction of the global economy and the potentially adverse effects in the financial position of our customers may extend the receivables recovery period for SQM, increasing its exposure to doubtful account risk. While measures have been taken to minimize such risk, the global economic situation may result in losses that might have a material adverse effect on the Company’s business, financial position or results of operations.

To mitigate these risks, SQM actively controls debt collection and has established certain safeguards which include loan insurance, letters of credit, and prepayments for a portion of receivables.

Financial investments correspond to time deposits with maturities exceeding 90 days and less than 360 days from the investment date, so they are not exposed to significant market risks.

The credit quality of financial assets that are neither past due nor impaired can be assessed by reference to external credit ratings (if available) or to historical information about counterparty default rates:

| Note 4 | Financial risk management, continued

| 4.2.3 | Currency risk

As a result of its influence on price level determination as well as its relationship with cost of sales, and since a significant portion of the Company’s business transactions are performed in that foreign currency, the functional currency of SQM is the United States dollar. However, the global business activities of the Company expose it to the foreign exchange fluctuations of several currencies with respect to the value of the U.S. dollar. Accordingly, SQM has entered into hedge contracts to mitigate the exposure generated by its main mismatches (assets, net of liabilities) in currencies other than the U.S. dollar against foreign exchange fluctuation. These contracts are periodically updated depending on the mismatch amount to be hedged in such currencies. Occasionally, and subject to the Board of Directors’ approval, in the short-term the Company insures cash flows from certain specific items in currencies other than the U.S. dollar.

A significant portion of the Company’s costs, particularly payroll, is denominated in Chilean pesos. Accordingly, an increase or decrease in the exchange rate against the U.S. dollar would affect the Company’s profit for the period. Approximately US$370 million of the Company’s costs are denominated in Chilean pesos. A significant portion of the effect of such obligations on the statement of financial position is hedged by derivative instrument transactions on the balance mismatch in such currency.

As of December 31, 2017, the Company recorded derivative instruments classified as currency and interest rate hedges associated with all the bonds payable, denominated in UF, with a fair value of US$5 million against SQM. As of December 31, 2016, this amounts to US$41 million against SQM.

As of December 31, 2017, the Chilean peso to U.S. dollar exchange rate was Ch$614.75 per US$1.00 (Ch$ 669.47 per US$ 1.00 as of December 31, 2016).

Notes to the Consolidated Financial Statements as of December 31, 2017

| Note 4 | Financial risk management, continued

| 4.2.4 | Interest rate risk

Interest rate fluctuations, primarily due to the uncertain future behavior of markets, may have a material impact on the financial results of the Company.

The Company has current and non-current debts valued at the LIBOR rate, plus a spread. The Company is partially exposed to fluctuations in this rate, as SQM currently holds hedging derivative instruments to hedge a portion of its liabilities subject to LIBOR rate fluctuations.

As of December 31, 2017, the Company has no financial liabilities linked to variations in the LIBOR rate and, therefore, significant increases in that rate would not impact its financial position.

In addition, as of December 31, 2017, the Company's financial liabilities are mainly concentrated in the long-term and approximately 7% have maturities of less than 12 months, decreasing in the process the exposure to changes in interest rates.

| 4.2.5 | Liquidity risk

Liquidity risk relates to the funds needed to comply with payment obligations. The Company’s objective is to maintain financial flexibility through a comfortable balance between fund requirements and cash flows from regular business operations, bank borrowings, bonds, short term investments, and marketable securities, among others.

The Company has an important capital expense program which is subject to change over time.

On the other hand, world financial markets go through periods of contraction and expansion that are unforeseeable in the long-term and may affect SQM’s access to financial resources. Such factors may have a material adverse impact on the Company’s business, financial position and results of operations.

SQM constantly monitors the matching of its obligations with its investments, taking due care of maturities of both, from a conservative perspective, as part of this financial risk management strategy. As of December 31, 2017, the Company had unused, available revolving credit facilities with banks, for a total of approximately US$248 million.

The position in other cash and cash equivalents generated by the Company are invested in highly liquid mutual funds with an AAA risk rating.

| 6.2 | Parent entity

As provided in the Company’s by-laws, no shareholder can concentrate more than 32% of the Company’s voting right shares and therefore there is no controlling entity.

| 6.3 | Joint arrangements of controlling interest

Sociedad de Inversiones Pampa Calichera S.A., Potasios de Chile S.A., and Inversiones Global Mining (Chile) Ltda., collectively the Pampa Group, are the owners of a number of shares that as of December 31, 2017 are equivalent to 29.97% of the current total amount of issued, subscribed and fully-paid shares in the Company. In addition, Kowa Company Ltd., Inversiones La Esperanza (Chile) Limitada, Kochi S.A. and La Esperanza Delaware Corporation, collectively the Kowa Group, are the owners of a number of shares equivalent to 2.12% of the total amount of issued, subscribed and fully-paid shares of SQM S.A.

The Pampa Group and the Kowa Group have informed SQM S.A., the Financial Markets Commission (formerly the Chilean SVS), and the relevant stock exchanges in Chile and abroad that they are not and have never been mutually related parties. This is independent of the fact that on December 21, 2006 the two Groups entered into a Joint Action Agreement (JAA) related to those shares. Consequently, neither the Pampa Group nor the Kowa Group individually owns more than 32% of the voting right capital of SQM S.A.

This Joint Action Agreement has not transformed the Pampa and Kowa Groups into mutually related parties. The Joint Action Agreement has only transformed the current controller of SQM S.A., composed of the Pampa Group, and the Kowa Group, into related parties of SQM S.A.

O |  |  | 58,748 |  |  | UF |  | 02/01/2022

The Company uses cross currency swap derivative instruments to hedge the possible financial risk associated with the volatility of the exchange rate associated with Chilean pesos and UF. The objective is to hedge the exchange rate financial risks associated with bonds payable. Hedges are documented and tested to measure their effectiveness.

Notes to the Consolidated Financial Statements as of December 31, 2017

| Note 10 | Financial instruments (continued)

| 10.3 | Hedging assets and liabilities, continued

Based on a comparison of critical terms, hedging is highly effective, given that the hedged amount is consistent with obligations maintained for bonds denominated in Chilean pesos and UF. Likewise, hedging contracts are denominated in the same currencies and have the same expiration dates of bond principal and interest payments.

Hedge Accounting

The Company classifies derivative instruments as hedging that may include derivative or embedded derivatives either as fair value hedge derivative instruments, cash flow hedge derivative instruments, or hedge derivative instruments for net investment in a business abroad.

a) Fair value hedge

Changes in fair values of derivative instruments classified as fair value hedge derivative instruments are accounted for in gains and losses immediately along with any change in the fair value of the hedged item that is attributable to the risk being hedged.

The Company documents the relationship between hedge instruments and the hedged item along with the objectives of its risk management and strategy to carry out different hedging transactions. In addition, upon commencement of the period hedged and then on a quarterly basis, the Company documents whether hedge instruments have been efficient and met the objective of hedging market fluctuations. For this purpose, we use the effectiveness test. A hedge instrument is deemed effective if the effectiveness test result is between 80% and 125%.

The hedge instruments are classified as effective or not effective on the basis of the effectiveness test results. At present, hedges are classified as effective on the basis of the effectiveness tests. This note includes the detail of fair values of derivatives classified as hedging instruments.

b) Cash flow hedges

Cash flow hedges cover exposure to the cash flow variations attributable to a risk associated with a specific transaction that is very likely to be executed, which may have material effects on the results of the Company.

| 10.8 | Fair value measurement of assets and liabilities

Financial assets and liabilities measured at fair value consist of Options and Forwards hedging the mismatch in the balance sheet and cash flows, Cross Currency Swaps (CCS) to hedge bonds issued in local currency ($/UF), and Interest Rate Swaps (IRS) to hedge LIBOR rate debt issued.

The value of the Company’s assets and liabilities recognized by CCS contracts is calculated as the difference between the present value of discounted cash flows of the asset (pesos/UF) and liability (US$) parts of the derivative. In the case of the IRS, the asset value recognized is calculated as the difference between the discounted cash flows of the asset (variable rate) and liability (fixed rate) parts of the derivative. Forwards: Are calculated as the difference between the strike price of the contract and the spot price plus the forwards points at the date of the contract. Options: The value recognized is calculated using the Black-Scholes method.

In the case of CCS, the entry data used for the valuation models are UF, peso, USD and basis swap rates. In the case of fair value calculations for IRS, the FRA (Forward Rate Agreement) rate and ICVS 23 Curve (Bloomberg: cash/deposits rates, futures, swaps). In the case of forwards, the forwards curve for the currency in question is used. Finally, with options, the spot price, risk-free rate and volatility of exchange rate are used, all in accordance with the currencies used in each valuation. The financial information used as entry data for the Company’s valuation models is obtained from Bloomberg, the well-known financial software company. Conversely, the fair value provided by the counterparties of derivatives contracts is used only as a control and not for valuation.

The effects on profit or loss of movements in these amounts may be recognized in the caption Finance costs, foreign currency translation gain (loss) or cash flow hedges in the statement of comprehensive income, depending on each particular case.

The fair value measurement of debt is only performed to determine the present market value of secured and unsecured long-term obligations; bonds denominated in local currency (Ch$/UF) and foreign currency (US$), credits denominated in foreign currency (US$), which is classified under Level 2 in the fair value hierarchy established by IFRS.

The value of the Company’s reported liabilities is calculated as the present value of discounted cash flows at market rates at the time of valuation, taking into account the maturity date and exchange rate. The entry data used for the model includes the UF and peso rates, which are obtained using Bloomberg, the well-known financial software company and the “Asociación de Bancos e Instituciones Financieras” (ABIF) (Association of Banks and Financial Institutions’).

Fair value hierarchy

The fair value hierarchy is detailed as follows:

| a) | Level 1: using quoted prices (unadjusted) only in active markets.

| b) | Level 2: when in any phase in the valuation process inputs other than quoted prices have been used in Level 1 that are observable directly in markets.

| c) | Level 3: inputs for the asset or liability that are not based on observable market data.

The valuation technique used for determining fair value of our hedging instruments is that indicated in Level 2.

| 10.10 | Estimated fair value of financial instruments and financial derivatives

As required by IFRS 7, the following information is presented for the disclosure of the estimated fair value of financial assets and liabilities.

Although inputs represent Management's best estimate, they are subjective and involve significant estimates related to the current economic and market conditions, as well as risk features.

Methodologies and assumptions used depend on the risk terms and characteristics of instruments and include the following as a summary:

| - | Cash equivalent approximates fair value due to the short-term maturities of these instruments.

| - | The fair value of trade receivables, current is considered to be equal to the carrying amount due to the maturity of such accounts at short-term.

| - | The fair value of other current financial liabilities is considered to be equal to their carrying values.

| - | For interest-bearing liabilities with original maturity of more than a year, fair values are calculated by discounting contractual cash flows at their original current market rates with similar terms.

| - | The fair value of debt is considered in Level 2.

| - | For forward and swap contracts, fair value is determined using quoted market prices of financial instruments with similar characteristics.

a) Estimated useful lives or amortization rates used for finite identifiable intangible assets

Finite useful life measures the lifetime or the number of productive units or other similar variables which constitute its useful life.

The estimated useful life for software is 3 and 6 years. For other finite useful life assets, the period in which they are amortized relates to periods defined by contracts or the rights which generate them.

Intellectual property rights, patents and other industrial property rights, service and exploitation rights, mainly relate to water rights and have a finite useful life to the extent to which they are subject to a fixed-term contract or otherwise they are considered to be indefinite.

b) Method used to express the amortization of identifiable intangible assets (life or rate)

The method used to express the amortization is useful life, and estimated tons to be extracted in the case of mining claims.

e) Other information to be disclosed on intangible assets

SQM has property rights and mining concessions from the Chilean Government that are intended for the exploration and exploitation of saltpeter and brine. Such rights incur no initial cost other than registration costs, which are insignificant.

Also, SQM has acquired mining concessions from third-parties other than the Chilean Government, which have been recognized at acquisition cost and are amortized as the corresponding area is exploited based on the tons estimated to be extracted.

Expenses prior to obtaining the mining concessions are recognized in profit or loss for the year as incurred.

As of December 31, 2017, the subsidiary Soquimich Comercial S.A. presented an impairment for the acquisition of the commercial agent of Sociedad Agrocom Ltda.

| 14.3 | Detail of property, plant and equipment pledged as guarantee

There are no restrictions in title or guarantees for compliance with obligations that affect property, plant and equipment.

| 14.4 | Impairment of assets

As indicated in Note 3.28 to the financial statements, the recoverable amount of property, plant and equipment is measured provided that there is an indication that the asset could be impaired. As of December 31, 2017, there were no impairment adjustments and as of December 31, 2016 there were impairment adjustments associated with the closure of railway facilities for the transportation of products.

Railway for transportation of products from the Coya Sur location and the Port of Tocopilla

As a result of the rain storms that affected the Tocopilla Zone at the beginning of August 2015, SQM S.A. confirmed damages to several sections of the railway between the Coya Sur and Tocopilla sites. As of that date, the Company has used trucks to replace rail transportation. SQM has carried out several internal and external studies with the purpose of determining what would be necessary to repair the damage to the railway.

These reports revealed that repairing the damage would entail high long-term costs, and it is therefore not convenient to repair the railway in the short- to medium-term. This decision does not affect the production process or imply additional employee reductions.

Consequently, SQM has adjusted the value of the assets associated with the railway (fixed equipment, facilities and rolling stock), which has translated into a charge of approximately US$32 million, which is reflected in the line other expenses by function in the consolidated statement of income for the period. This amount represents around 0.8% of SQM’s total assets and 11% of revenue reported at the end of December 2016.

Interest capitalized in construction-in-progress:

The amount capitalized for this concept amounted to ThUS$4,382 as of December 31, 2017 and ThUS$ 5,406 as of December 31, 2016.

Financing costs are not capitalized for periods which exceed the normal term of acquisition, construction or installation of the asset, such as occur with delays, interruptions or a temporary suspension of the project due to technical, financial or other issues, which prevent the asset from being maintained in good condition for its use.

| 15.2 | Policies on defined benefit plan

This policy is applied to all benefits received for services provided by the Company's employees.

Short-term benefits for active employees are represented by salaries, social welfare benefits, paid time off, sickness and other types of leave, profit sharing and incentives and non-monetary benefits; e.g., healthcare service, housing, subsidized or free goods or services. These will be paid in a term which does not exceed twelve months.

The Company only provides compensation and benefits to active employees, with the exemption of SQM North America, which applies the definitions under 15.4 below.

SQM maintains incentive programs for its employees based on their personal performance, the Company’s performance and other short-term and long-term indicators.

For each incentive bonus delivered to the Company’s employees, there will be a disbursement in the first quarter of the following year and this will be calculated based on profit for the period at the end of each period applying a factor obtained subsequent to each employee’s appraisal process.

Employee benefits include retention bonuses for the Company’s executives, which are linked to the Company’s share price and are paid in cash. The short-term portion is presented as a provision for current employee benefits and the long-term portion as non-current.

Staff severance indemnities are agreed and payable based on the final salary, calculated in accordance with each year of service to the Company, with certain maximum limits in respect of either the number of years or in monetary terms. In general, this benefit is payable when the employee or worker ceases to provide his/her services to the Company and there are a number of different circumstances through which a person can be eligible for it, as indicated in the respective agreements; e.g., retirement, dismissal, voluntary retirement, incapacity or disability, death, etc.

Law No. 19,728 published on May 14, 2001 which became effective on October 1, 2002 required “Compulsory Unemployment Insurance” in favor of all dependent employees regulated by the Chilean Labor Code. Article 5 of this law established that this insurance is paid through monthly contribution payments by both the employee and the employer.

| 15.3 | Other long-term benefits

The other long-term benefits relate to staff severance indemnities and are recorded at their actuarial value, and an executive compensation plan (see Note 16).

Staff severance indemnities at actuarial value |  | 12/31/2017 |  |  | 12/31/2016 |

Total other non-current liabilities |  |  | 33,932 |  |  |  | 22,532 |

The actuarial assessment method has been used to calculate the Company’s obligations with respect to staff severance indemnities, which relate to defined benefit plans consisting of days of remuneration per year served at the time of retirement under conditions agreed in the respective agreements established between the Company and its employees.

Under this benefit plan, the Company retains the obligation to pay staff severance indemnities related to retirement, without establishing a separate fund with specific assets, which is referred to as not funded. The discount interest rate of expected flows to be used was 4.89%.

Benefit payment conditions

The staff severance indemnity benefit relates to remuneration days for years worked for the Company without a limit being imposed in regard of amount of salary or years of service. It applies when employees cease to work for the Company because they are made redundant or in the event of their death. This benefit is applicable up to a maximum age of 65 for men and 60 for women, which are the usual retirement ages according to the Chilean pensions system as established in Decree Law 3,500 of 1.980.

Methodology

The Company’s benefits obligation under IAS 19 Projected Benefit Obligation (PBO) is determined as follows:

To determine the Company's total liability, we used computer software to develop a mathematical simulation model using the data for each individual employee.

| 15.3 | Other long-term benefits, continued

This model considered months as discrete time; i.e., the Company determined the age of each person and his/her salary on a monthly basis according to the growth rate. Thus, information on each person was simulated from the beginning of his/her employment contract or when he/she started earning benefits up to the month in which he/she reaches normal retirement age, generating in each period the possible retirement according to the Company’s turnover rate and the mortality rate according to the age reached. When he/she reaches the retirement age, the employee finishes his/her service for the Company and receives a retirement indemnity.

The methodology followed to determine the accrual for all the employees covered by agreements took account of the turnover rates and the mortality rate RV-2009 established by the Financial Markets Commission (formerly the Chilean Superintendence of Securities and Insurance) to calculate pension-related life insurance reserves in Chile according to the Accumulated Benefit Valuation or Accrued Cost of Benefit Method. This methodology is established in IAS 19 on Retirement Benefit Costs.

| 15.4 | Post-employment benefit obligations

Our subsidiary SQM North America, together with its employees established a pension plan until 2002 called the “SQM North America Retirement Income Plan”. This obligation is calculated measuring the expected future forecast staff severance indemnity obligation using a net salary gradual rate of restatements for inflation, mortality and turnover assumptions, discounting the resulting amounts at present value using the interest rate defined by the authorities.

Since 2003, SQM North America offers to its employees’ benefits related to pension plans based on the 401-K system, which do not generate obligations for the Company.

| Note 16 | Executive compensation plan

The Company currently has a compensation plan with the purpose of motivating the Company’s executives and encouraging them to remain with the Company, by granting payments based on the following:

Average Share Price Spread

Plan characteristics

This compensation plan is related to the Company’s performance through the SQM Series B share price (Santiago Stock Exchange).

Plan participants

A total of 39 Company executives are entitled to this plan, provided that they continue to work for the Company through to the end of 2020. The payment dates, if applicable, will be during the first quarter of 2021.

Compensation

The compensation payable to each executive is calculated by multiplying a) by b):

| a) | The average price of Series B shares on the Santiago Stock Exchange during the fourth quarter of 2020, at its equivalent amount in United States dollars (with a maximum amount or limit amount of US$54 per share),

| b) | By a number equal to the quantity of shares that have been individually assigned to each executive included in the plan.

This compensation plan was approved by the Company’s Board of Directors and its application started on January 1, 2017.

The plan’s effect considers 533,476 shares with an impact amounting to ThUS$6,487 on the profit and loss for the year ended December 31, 2017, which is recognized on an accrual basis.

The detail and movements in the funds of equity accounts are shown in the consolidated statement of changes in equity.

| 17.1 | Capital management

The main object of capital management relative to the administration of the Company’s financial debt and equity is to ensure the regular conduct of operations and business continuity in the long term, with the constant intention of maintaining an adequate level of liquidity and in compliance with the financial safeguards established in the debt contracts in force. Within this framework, decisions are made in order to maximize the value of SQM.

Capital management must comply with, among others, the limits contemplated in the Financing Policy approved by the Shareholders’ Meeting, which establish a maximum consolidated indebtedness level of 1.5 times the debt to equity ratio. This limit can be exceeded only if the Company’s management has first obtained express approval at an Extraordinary Shareholders’ Meeting.

In addition, capital management must comply with the external capital requirements (or covenants) imposed in its financial obligations, which regulate the indebtedness level to 1.2 times, its strictest level.

In conjunction with the level of indebtedness, it is also important for the Company to maintain a comfortable profile of maturities for its financial obligations, in order to oversee the relation between its short-term financial obligations and the long-term maturities, and the relation they have with the Company’s asset distribution. Consequently, the Company has maintained a liquidity level of 3 times during the last periods.

The Company’s management controls capital management based on the following ratios:

Reserves for foreign currency translation differences

This balance reflects retained earnings for changes in the exchange rate when converting the financial statements of subsidiaries whose functional currency is that of each company’s origin country and the presentation currency is the US dollar.

Reserve for cash flow hedges

The Company maintains, as hedge instruments, financial derivatives related to obligations with the public issued in UF and Chilean pesos. Changes from the fair value of derivatives designated and classified as hedges are recognized under this classification.

Reserve for gains and losses from financial assets measured at fair value through other comprehensive income

This caption includes investments in shares where the Company has no significant influence and these have accordingly been measured at fair value through equity. In the event that such equity instruments are fully or partially disposed of, the proportional accumulated effect of accumulated fair value will be transferred to profit or loss.

Reserve for actuarial gains or losses in defined benefit plans

For domestic subsidiaries the effects of changes in assumptions are considered, mainly changes in the discount rate.

The subsidiary SQM North America has established pension plans for its retired employees that are calculated by measuring the projected obligation of staff severance indemnities using a net salary progressive rate net of adjustments to inflation, mortality and turnover assumptions, deducting the resulting amounts at present value using a 5.5% interest rate for 2016 and 2015.

| 17.4 | Dividend policies

As required by Article 79 of the Chilean Companies Act, unless otherwise decided by unanimous vote of the holders of issued and subscribed shares, we must distribute a cash dividend in an amount equal to at least 30% of our consolidated profit for the year ended as of December 31, unless and except to the extent it has a deficit in retained earnings (losses not absorbed in prior years).

At an extraordinary meeting held on April 11, 2017, the Company’s Board of Directors made a recommendation for discussion at the Ordinary Shareholders’ Meeting (the Meeting), which was held on April 28, 2017, that the Company should distribute and pay dividends based on 100% of the Company’s net profit for distribution for the financial year 2016. This recommendation was accepted by the Meeting.

For 2017, the Company has defined the following dividend policy: (a) To distribute and pay a dividend to the respective shareholders a percentage of the profits to be determined as follows:

(i) 100% of the profit for 2017 if all the following financial parameters are met: (a) that the total of cash and cash equivalents and other current financial assets (“Cash”) divided by the addition of other current financial liabilities (the “Short-term Financial Liabilities”) is equal to or more than 2.5 times, and (b) the total of current liabilities and non-current liabilities (“Total Liabilities”) divided by total equity (“Equity”) is equal to or less than 1.1 times.

(ii) 80% of profit for 2017 if all the following financial parameters are met: (a) that Cash divided by Short-term Financial Liabilities is equal to or more than 2.0 times, and (b) Total Liabilities divided by Total Equity is equal to or less than 1.2 times.

(iii) 60% of profit for 2017 if all the following financial parameters are met: (a) that Cash divided by Short-term Financial Liabilities is equal to or more than 1.5 times, and (b) Total Liabilities divided by Total Equity is equal to or less than 1.3 times. Should none of these parameters be met, the Company will distribute and pay as dividend 50% of the profit for 2017 to the respective shareholders.

For the year ended December 31, 2017, the foregoing financial parameters are met for the Company to distribute and pay as a final dividend 100% of the profits for the year 2017.

Change in 2016 Dividend Policy

On November 23, 2016, the provisional dividend described above and the Dividend Policy for the 2016 fiscal year were approved as communicated at the Ordinary Shareholders’ Meeting of April 26, 2016 (the “Dividend Policy”), was amended as follows:

(i) not to distribute more provisional dividends during 2016 except for the dividend approved on that date, to be paid during the last quarter of 2016.

(ii) the remaining amount of net profit for 2016, if any, to be retained and used for the financing of own operations or activities associated with one or more of the Company’s investment projects, without prejudice, however, to the possible future capitalization of all or a portion of this or its distribution as a dividend as determined by the shareholders at the Company’s Ordinary Shareholders’ Meeting.

(iii) The Dividend Policy described above relates to the intent or expectation of the Board of Directors with respect to such matter. Consequently, compliance with this Dividend Policy is necessarily dependent on the net profits that are finally obtained and the profit or loss indicated by the Company’s regular forecasts.

If the Dividend Policy is subject to substantive change, the Board of Directors will communicate and inform its shareholders about any such change in a timely manner in the form of an essential event. On March 22, 2016, the Company communicated that the Directors of Sociedad Química y Minera de Chile S.A. (SQM), at the Ordinary Meeting had unanimously agreed the following:

To partially amend “SQM S.A.’s Dividend Policy for the 2015 fiscal year with the main purpose of including in such “Policy” the payment of an interim dividend of US$150,000,000, equivalent to US$0.56992 per share, to be paid with a charge to retained earnings of SQM S.A.”. This was reported to the Ordinary Shareholders’ Meeting of April 24, 2015.

The Company and its subsidiaries have been involved and will probably continue to be involved either as plaintiffs or defendants in certain judicial proceedings that have been and will be heard by the arbitration or ordinary courts of justice that will make the final decision. Those proceedings that are regulated by the appropriate legal regulations are intended to exercise or oppose certain actions or exceptions related to certain mining claims either granted or to be granted and that do not or will not affect in an essential manner the development of the Company and its subsidiaries.

Soquimich Comercial S.A. has been involved and will probably continue being involved either as plaintiff or defendant in certain judicial proceedings through which it intends to collect and receive the amounts owed, the total nominal value of which is approximately US$1.2 million.

The Company has made efforts and continues making efforts to obtain payment of certain amounts that are still owed it on occasion of their activities. Such amounts will continue to be required using judicial or non-judicial means by the plaintiffs, and the actions and exercise related to these are currently in full force and effect.

The Company and its subsidiaries have received no legal notice on lawsuits other than those indicated above, which exceed US$0.2 million.

| 19.4 | Environmental contingencies

On June 6, 2016, the Superintendence of the Environment (the “SMA”) filed charges against the Company with respect to the Pampa Hermosa project for possible noncompliance with RCA 890/2010.

This relates to charges regarding certain variables in the follow-up plan and through the implementation of a mitigation measure contemplated in the related environmental impact assessment. The Company submitted a Compliance Program to the SMA for its approval. This program details the actions and commitments that the Company will perform to overcome the objections filed by the environmental authority. On June 29, 2017, the SMA rejected the Compliance Program submitted by the Company. On July 10, the Company presented the defense against the charges filed by the SMA. On December 13, 2017, the First Environmental Court of Antofagasta ordered the temporary and partial closure of the water extraction wells located in the Salar de Llamara. These wells allow the Company to extract around 124 liters/second of water, which is approximately 15% of the water used in Chile’s First Region.

Through a ruling dated November 28, 2016, which was modified by a ruling dated December 23, 2016, the SMA filed charges against SQM Salar for extracting brine in excess of authorized amounts, progressively impacting the vitality of algarrobo trees, delivering incomplete information, modifying variables and other matters.

SQM Salar has presented a compliance program detailing the actions and commitments it will carry out to address the SMA's objections. The SMA is reviewing the compliance program.

| 19.5 | Tax contingency

During 2015, the Company, SQM Salar and SQM Industrial submitted to the Chilean IRS four tax amendments (two by the Company, one by SQM Salar and one by SQM Industrial).

The first two (one for SQM and one for SQM Salar), after being approved by the SII, generated payments for taxes, interests and other charges for US$8.1 million. A provision for such amount was made in the profit or loss for the first quarter of 2015.

Additionally, during August 2015, the Chilean IRS was provided, for its review and approval, with the documentation necessary for amending the annual tax returns of the Company and SQM Industrial. As a result of such amendments, the Company paid an approximate sum of US$1.4 million for taxes, interests and other charges. This amount was recorded in a provision in the profit or loss for the second quarter of 2015.

Finally, during 2016, the last 12 invoices were amended with a payment of approximately US$50,000.

Accordingly, the SQM Group understands the internal analysis they have been performing has ended, the purpose of which was the identification of the expenses incurred by them during the fiscal years 2008 to 2014 and which could be a matter of tax amendment.

Because of the aforementioned amendments, the Company, SQM Salar and SQM Industrial might be affected by additional penalties established in the first subparagraph, No. 4 of Article 97 of the Tax Code, for an amount ranging between 50% and 300% of the taxes paid. The Company has not considered it necessary to make any provisions related to this possible additional penalty.

On August 26, 2016, SQM Salar filed with the Third Tax and Customs Court of the Metropolitan Region a tax claim against tax assessments Nos. 169, 170, 171 and 172, which seek to expand the application of the specific tax on mining activities for the exploitation of lithium. The amount involved is approximately ThUS$17,809. This claim is at the deliberation stage.

On March 24, 2017, SQM Salar filed with the Third Tax and Customs Court of the Metropolitan Region a tax claim against tax assessment No. 207 of 2016 and ruling No. 156 of 2016, both issued by the Chilean IRS, which seek to expand application of the specific tax on mining activities to include lithium exploitation for tax years 2015 and 2016. The amount involved is approximately US$14.4 million. This claim is at the deliberation stage.

The aforementioned amounts are classified as current tax assets, non-current as of December 31, 2017.

Notes to the Consolidated Financial Statements as of December 31, 2017

| Note 19 | Contingencies and restrictions (continued)

| 19.4 | Tax contingency, continued

Of the US$32.2 million under dispute, approximately US$25,2 million correspond to the potential specific tax on mining activities related to lithium and US$7.0 million correspond to an excess charge levied by the Chilean IRS. The Chilean IRS has not issued an assessment claiming differences in the specific tax on mining activities filed for the years 2016 and 2017. As of the date of these financial statements, SQM has not made any provisions for these possible differences.

If the Chilean IRS uses criteria similar to that used in previous years, it may issue an assessment in the future for the 2016 and 2017 financial years. It is reasonable to expect that should these assessments (for the years 2016 and 2017) be issued, the value would be approximately US$30 million (without considering potential interest and fines).

| 19.6 | Restricted or pledged cash

The subsidiary Isapre Norte Grande Ltda., in compliance with the provisions established by the Chilean Superintendence of Healthcare, which regulates the running of pension-related health institutions, maintains a guarantee in financial instruments delivered in deposits, custody and administration to Banco de Chile.

This guarantee, according to the regulations issued by the Chilean Superintendence of Healthcare is equivalent to the total sum owed to its members and medical providers. Banco de Chile reports the present value of the guarantee to the Chilean Superintendence of Healthcare and Isapre Norte Grande Ltda. on a daily basis. As of December 31, 2017, the guarantee amounts to ThUS$771.

Notes to the Consolidated Financial Statements as of December 31, 2017

| Note 24 | Reportable segments

| 24.1 | Reportable segments

General information:

The amount of each item presented in each operating segment is equal to that reported to the maximum authority that makes decisions regarding the operation, in order to decide on the allocation of resources to the defined segments and to assess its performance.

These operating segments mentioned are consistent with the way the Company is managed and how results will be reported by the Company. These segments reflect separate operating results that are regularly reviewed by the person responsible for operational decisions in order to make decisions about the resources to be allocated to the segment and assess its performance (See Note 24.2).

The performance of each segment is measured based on net income and revenues. Sales between segments are conducted using terms and conditions at current market rates.

Factors used to identify segments on which a report should be presented:

The segments covered in the report are strategic business units that offer different products and services. These are managed separately because each business requires different technology and marketing strategies.

Description of the types of products and services from which each reportable segment obtains its income from ordinary activities

The operating segments, which obtain income from ordinary activities, generate expenses and whose operating results are reviewed on a regular basis by the maximum authority who makes decisions regarding operations, relate to the following groups of products:

| 1. | Specialty plant nutrients

| 2. | Iodine and its derivatives

| 3. | Lithium and its derivatives

| 4. | Industrial chemicals

| 5. | Potassium

| 6. | Other products and services

Description of income sources for all the other segments

Information regarding assets, liabilities, profits and expenses that cannot be assigned to the segments indicated above, due to the nature of production processes, is included under the "Unassigned amounts” category of the disclosed information.

Basis of accounting for transactions between reportable segments

Sales between segments are made under the same conditions as those made to third parties, and how they are presented in the income statement is constantly monitored.

| F-165 |

Notes to the Consolidated Financial Statements as of December 31, 2017

| Note 24 | Reportable segments (continued)

| 24.1 | Reportable segments, continued

Description of the nature of the differences between measurements of results of reportable segments and the result of the entity before the expense or income tax expense of incomes and discontinued operations.

The information reported in the segments is extracted from the Company’s consolidated financial statements and therefore there is no need to prepare reconciliations between the data mentioned above and those reported in the respective segments, according to what is stated in paragraph 28 of IFRS 8, "Operating Segments".

For the process of cost allocation in inventory valuation, we identify the direct costs (can be assigned directly to a product) and the common costs (belong to processes of co-production, for example costs of common leaching for the production of iodine and nitrates). The direct costs are directly associated with the product and the common costs are allocated using percentages of sales, prices and inventory rotation.

The allocation of other common costs that are not included in the inventory valuation process, but go straight to the cost of sales, use similar criteria: the costs associated with a product or sales in particular are assigned to that particular product or sales, and the common costs associated with different products or business lines are allocated according to the sales.

Description of the nature of the differences between measurements of assets of reportable segments and the Company´s assets

Assets are not shown classified by segments, as this information is not readily available. Some of these assets are not separable by the type of activity by which they are affected since this information is not used by management in decision-making with respect to resources to be allocated to each defined segment. All assets are disclosed in the "unallocated amounts" category.

Description of the nature of the differences between measurements of liabilities of reportable segments and the Company’s liabilities

Liabilities are not shown classified by segments, as this information is not readily available. Some of these liabilities are not separable by the type of activity by which they are affected, since this information is not used by management in decision-making regarding resources to be allocated to each defined segment. All liabilities are disclosed in the "unallocated amounts" category.

|  | ThUS$ |  |  | ThUS$ |

Income tax is calculated based on the profit or loss for tax purposes that is applied to the effective tax rate applicable in Chile. As established by Law No.20,780, an income tax rate of 21% was set starting from 2014, a rate of 22.5% for 2015, a rate of 24% for 2016, a rate of 25.5% for 2017, and a rate of 27% starting from 2018.

On December 22, 2017, a Tax Reform was published in the United States, which introduced various modifications to the United States Tax System. This reform, among other things, reduced corporate income tax rates, modified international tax regulations and made significant changes in the way in which tax losses are considered recoverable. The main modification relates to the decrease in income tax rate from 34% to 21% starting on January 1, 2018 (Georgia’s corporate income tax rate remained at 6%).

The income tax rate for the main countries where the Company operates is presented below:

Country |  | Income tax 2017 |  |  | Income tax 2016 |
Spain |  |  | 25 | % |  |  | 25 | %
Belgium |  |  | 33,99 | % |  |  | 33,99 | %
Mexico |  |  | 30 | % |  |  | 30 | %
United States |  |  | 40 | % |  |  | 40 | %
South Africa |  |  | 28 | % |  |  | 28 | %

The provision for royalty is determined by applying the tax rate determined for the net operating income (NOI). Currently, the Company pays 5% for the application of the Tax Invariability Contract established with the Ministry of Economy in 2010.

In conclusion, both concepts represent the estimated amount the Company will have to pay for income tax and tax on mining.

Notes to the Consolidated Financial Statements as of December 31, 2017

| Note 26 | Income tax and deferred taxes (continued)

| 26.2 | Income tax and deferred taxes

Assets and liabilities recognized in the statement of financial position are offset if and only if:

| 1 | The Company has legally recognized before the right of the tax authority to offset the amounts recognized in these entries; and

| 2 | Deferred income tax assets and liabilities are derived from income tax related to the same tax authority on:

(i) the same entity or tax subject; or

(ii) different entities or tax subjects who intend either to settle current fiscal assets and liabilities for their net amount, or to realize assets and pay liabilities simultaneously in each of the future periods in which the Company expects to settle or recover significant amounts of deferred tax assets or liabilities.

Recognized deferred income tax assets are the income taxes that are to be recovered in future periods, related to:

| a) | deductible temporary differences.

| b) | the offsetting of losses obtained in prior periods and not yet subject to tax deduction; and

| c) | the offsetting of unused credits from prior periods.

The Company recognizes a deferred tax asset when there is certainty that these can be offset with tax income from subsequent periods, losses or fiscal credits not yet used, but solely as long as it is more likely than not that there will be tax earnings in the future against which to charge these losses or unused fiscal credits.

Recognized deferred tax liabilities refer to the amounts of income taxes payable in future periods related to taxable temporary differences.

| d.11) | Explanation of the relationship between expense (income) for tax purposes and accounting income.

In accordance with paragraph No 81, letter c) of IAS 12, the Company considers that the method that discloses most significant information for the users of its financial statements is the reconciliation of tax expense (income) to the result of multiplying income for accounting purposes by the tax rate in force in Chile. This option is based on the fact that the Parent and its subsidiaries incorporated in Chile generate almost the total amount of tax expense (income) and the fact that the amounts contributed by subsidiaries incorporated in foreign countries have no relevant significance within the context of the total amount of tax expense (income).

The Group’s Companies are potentially subject to income tax audits by tax authorities in each country. These audits are limited to a number of interim tax periods, which, in general, when they elapse, give rise to the expiration of these inspections,

Tax audits, due to their nature, are often complex and may require several years, Below, we provide a summary of tax periods that are potentially subject to verification, in accordance with the tax regulations in force in the country of origin:

Chile

According to article 200 of Decree Law No 830, the taxes will be reviewed for any deficiencies in terms of payment and to generate any taxes that might arise. There is a 3-year prescriptive period for such review, dating from the expiration of the legal deadline when payment should have been made. This prescriptive period can be extended to 6 years for the revision of taxes subject to declaration, when such declaration has not been filed or has been presented with maliciously false information.

Notes to the Consolidated Financial Statements as of December 31, 2017

| Note 28 | Mineral resource exploration and evaluation expenditure

Because of the nature of the operations of Sociedad Química y Minera de Chile S.A. and its subsidiaries and the type of exploration they conduct (which is different from other mining businesses, where the exploration process takes a significant amount of time), the exploration process and the definition of economic feasibility normally occur within the year. Accordingly, although expenditure is initially capitalized, it could be recognized in profit or loss for the same year should it not be technically and commercially feasible. This means that there is no significant expenditure that lacks a feasibility study at the end of the year.

Prospecting expenditure can be found in 4 different stages: execution, economically feasible, not economically feasible and under exploitation:

1. Execution: prospecting expenditures that are under execution and where the economic feasibility is not yet known are classified in the caption property, plant and equipment. As of December 31, 2017 and December 31, 2016, the balance amounted to ThUS$21,013 and ThUS$ 12,163, respectively,

2. Economically feasible: prospecting expenditure, which upon completion, has been determined to be economically feasible is classified in the caption non-current assets in other non-current non-financial assets. As of December 31, 2017 and December 31, 2016, this totaled ThUS$17,721 and ThUS$ 23,008 respectively,

3. Not economically feasible: Prospecting expenditure, which upon completion, has been determined to not be economically feasible is recorded in profit or loss. As of December 31, 2017 and December 31, 2016 there is no expenditure for such concept.

4. Under exploitation: Prospecting expenditure under exploitation is classified in the caption current assets in current inventories. These are amortized considering the exploited material. As of December 31, 2017 and December 31, 2016, the balance amounted to ThUS$521 and ThUS$ 674 respectively.

For the amount of capitalized expenditure, the total amount disbursed in exploration and evaluation of mineral resources as of December 31, 2017 was ThUS$6,024, and corresponded to non-metallic projects. Such expenditure mainly corresponds to research, including topographical, geological, exploratory drilling and sampling studies.

With respect to this expenditure, the Company classifies it in accordance with paragraph 9 of IFRS 6:

Exploration expenditure where the mineral has low ore grade that is not economically exploitable is debited directly to profit or loss.

If studies determine that the ore grade is economically exploitable, it is classified in other non-current assets in the caption ground studies and prospecting expenses. At the time of making the decision to exploit the zone, it is classified in the caption inventories as part of the cost of raw materials required for production purposes.

| Note 29 | Lawsuits and complaints

Lawsuits and complaints

During 2015, the Chilean IRS has filed several lawsuits and complaints against a number of individuals related to the so-called “SQM Case”, which are associated with the irregular financing of politicians. Amongst those affected by these legal claims are the legal representatives of the Company: the CEO, Patricio de Sominihac T. and the Vice President of Corporate Services, Ricardo Ramos R. Basically, those lawsuits and complaints relate to alleged tax crimes associated with a possible undue decrease in the taxable net income of the Company and two of its subsidiaries over the last seven years by recording as expenses in their accounting records invoices and fee receipts, which could be considered to be ideologically false. Such legal actions are also filed against the taxpayers who provided the tax documents that allowed the alleged performance of the related illicit acts. In December 2017, the Public Prosecutor confirmed that no charges will be brought against the CEO or Vice President of Corporate Services.

Actions performed by the Authority

The Public Ministry and the Chilean IRS (Servicio de Impuestos Internos (SII)) have performed a number of actions within the framework of the so-called “SQM Case”, where the Company and its executives have provided their cooperation. Several of the Company’s executives have granted access to their computers and made several statements at the request of the Prosecutors responsible for the investigation. Additionally, SQM has provided physical and digital copies of its accounting records and its subsidiaries’ accounting records. In addition, SQM has also provided the Public Ministry with its email files and all the documentation that has been required by the related authority.

Shearman & Sterling and Ad-Hoc Committee

On February 26, 2015, the Board of Directors of SQM established an ad-hoc committee comprised of three directors (the “Ad-hoc Committee”), which was authorized to conduct an investigation on the matters described in the preceding paragraph and to request any external advisory services it deemed necessary. The original members of the Ad-hoc Committee were José María Eyzaguirre B., Juan Antonio Guzmán M. and Wolf von Appen B.

The Ad-hoc Committee hired its own legal counsel in Chile and the United States as well as forensic accountants in the United States to support its internal investigation. The U.S. attorneys hired by the Ad-hoc Committee were mainly charged with reviewing the important facts and analyzing them in the context of the United States Foreign Corrupt Practices Act (“FCPA”). However, the Ad-hoc Committee’s factual conclusions were shared with both Chilean authorities and U.S. authorities.

On December 15, 2015, the Ad-hoc Committee presented the conclusions of its investigation to the Board of Directors of SQM. In addition to discussing the facts related to the referenced payments, the Ad-hoc Committee concluded that, for the purposes of the FCPA:

| a. | payments were identified that had been authorized by the former CEO of SQM for which the Company did not find sufficient supporting documentation;

| b. | no evidence was identified that demonstrated that such payments were made in order to prompt a public official to act or abstain from acting in order to help SQM obtain economic benefits;

| c. | in relation to the cost centers managed by the former CEO of SQM, it was concluded that the Company's books did not accurately reflect the transactions in question but that these transactions were determined to be quantitatively immaterial in comparison to SQM's equity, sales, expenses and profits during that period; and that

| d. | SQM's internal controls were insufficient to supervise the expenses within the cost center managed by the former CEO of SQM and relied on the proper use of resources by Patricio Contesse G. himself.

After the Ad-hoc Committee presented its conclusions to the Board of Directors, the Company voluntarily shared these conclusions with the Chilean and U.S. Authorities (including the SEC and the U.S. Department of Justice (“DOJ”)) and has since collaborated by handing over documents and additional information requested by these authorities regarding this investigation.”

Investigation by the Department of Justice and the Securities Exchange Commission

SQM informed the US regulating entities (Department of Justice and Securities and Exchange Commission) about the investigation being performed by Shearman & Sterling, in conformity with the standards effective in the United States of America. The outcome of the investigation was delivered to these regulating entities, which have started investigations to determine the existence of possible noncompliance with FCPA (Foreign Corruption Practices Act) or internal control standards.

On January 13, 2017, the Company entered into agreements with the Department of Justice (the “DOJ”) and the Securities and Exchange Commission (the “SEC”), both based in the United States of America (the “United States”), with respect to the investigations that those agencies had conducted as a result of payments to suppliers and entities that might have been related to politically exposed persons during the years from 2008 through 2015, which resulted in the performance of an internal investigation at the Company through an Ad-hoc Committee from its Board of Directors and which was led by the law firm Shearman & Sterling (the “Investigated Facts”). Because the Company’s securities are traded in the United States, the Company is subject to U.S. legislation. The Company has voluntarily provided the results of its internal investigation and supporting documentation to the DOJ, the SEC and the relevant Chilean authorities.

In conformity with the terms of the agreement entered into with the DOJ, referred to as Deferred Prosecution Agreement (the “DPA”), the Company has accepted that the DOJ presents (i) a charge for the infractions referred to the absence of implementation of effective internal accounting systems and internal accounting controls and (ii) a charge for infractions related to failure to properly maintain accounting ledgers, records and sections with respect to the Investigated Facts. By virtue of the DPA, the DOJ has agreed not to prosecute those charges against the Company for a period of 3 years, releasing the Company from such responsibility after such period to the extent that within such term the Company complies with the terms in the DPA, which include the payment of a fine of US$15,487,500 (“U.S. dollars”) and the acceptance of an external monitor for a term of 24 months (the “Monitor”) who will evaluate the Company’s compliance program and a subsequent independent report by the Company for an additional year.

With respect to the agreement entered into with the SEC, the Company has agreed to (i) pay a fine of US$15 million and (ii) maintain the Monitor for the aforementioned term.

The SEC has issued a Cease and Desist Order which does not identify any other events of noncompliance with the standards applicable in the United States.

The aforementioned amounts of approximately US$30.5 million were reflected in the profit or loss of SQM during the fourth quarter of 2016 in the line item Other expenses by function.

| Note 30 | Sanction proceedings

On April 1, 2015, the SVS started an administrative proceeding against five Directors of the Company for allegedly not having provided to the market on a timely and truthful basis information which could be significant for making investment decisions. Such information mainly relates to the preliminary estimate of the impact on the Company’s financial statements of certain expenses paid by the Company between 2008 and 2014 and which might not qualify as expenses under current Chilean tax regulations because of the absence of supporting documentation.

On September 30, 2015, Sociedad Química y Minera de Chile S.A. informed that the CMF had decided to penalize Patricio Contesse Fica, Julio Ponce Lerou, Juan Antonio Guzmán Molinari and Wolf von Appen Berhmann, all former directors of the Company, and Hernan Büchi Buc – a current director – for not having informed the market in a timely manner in March 2015 in the form of an essential event as directors of the Company at that time regarding the expenses SQM incurred during certain years for which the Company did not have sufficient supporting documentation or that could be considered expenses not necessary for producing income. This penalty, consisting of a fine of UF 1,000 for each person, can be appealed by the affected parties before the CMF or the courts of law.

| Note 31 | Railway for transportation of products between the site Coya Sur and the Port of Tocopilla

As a result of the rain storms that affected the Tocopilla Zone at the beginning of August 2015, SQM S.A. confirmed damages to several sections of the railway between the Coya Sur and Tocopilla sites. As of that date, the Company has used trucks to replace rail transportation. SQM has carried out several internal and external studies with the purpose of determining what would be necessary to repair the damage to the railway.

These reports revealed that repairing the damage would entail high long-term costs, and it is therefore not convenient to repair the railway in the short- to medium-term. This decision does not affect the production process or imply additional employee reductions.

Consequently, SQM has adjusted the value of the assets associated with the railway (fixed equipment, facilities and rolling stock), which has translated into a charge of approximately US$32 million, which is reflected in the line other expenses by function in the consolidated statement of income for the period. This amount represents around 0.7% of SQM’s total assets reported at the end of September 2016.

| 32.2 | Disclosures on events occurring after the reporting date

On January 17, 2018 SQM and CORFO (Corporación de Formento de la Producción) have reached an agreement to end the arbitration process directed by the arbitrator, Mr. Héctor Humeres Noguer, in the case 1954-2014 of the Arbitration and Mediation Center of Santiago Chamber of Commerce (Centro de Arbitrajes y Mediación de la Cámara de Comercio de Santiago) and other cases accumulated to it (the “Agreement”). The Agreement has been reached within the conciliation process of the arbitration and on the basis presented by the arbitrator to the parties. Both SQM´s Board of Directors and the Board of CORFO have approved the Agreement.

The Agreement includes a total payment of US$17.5 million plus agreed interest which a subsidiary of SQM, SQM Salar S.A. ("SQM Salar"), shall pay CORFO. This payment does not imply the recognition of having owed any amount to CORFO, and has been agreed to with the sole purpose of ending the disputes between the parties.

Additionally, the Agreement includes important amendments to the lease agreement and project agreement signed between CORFO and SQM in 1993, which are the contracts that currently permit the mining operations of SQM Salar in the Salar de Atacama (the "Contracts"). The main modifications are detailed below, and will become effective once the following resolutions have been issued: (i) the approval resolution of the Contracts by the CORFO Council, and (ii) the resolution that executes the respective approval agreement by the Chilean Nuclear Energy Commission (CCHEN):

| a. | An increase in lease payments by increasing the lease rates associated with the sale of the different products produced in the Salar de Atacama:

| · | In regard to lithium carbonate, the current rate of 6.8% on FOB sales shall be changed to the following structure of progressive rates based on the final sale price:

Price US$/MT Li2CO3 |  | Lease payment rate |
$0 - $4,000 |  |  | 6.8 | %
$4,000 - $5,000 |  |  | 8.0 | %
$5,000 - $6,000 |  |  | 10.0 | %
$6,000 - $7,000 |  |  | 17.0 | %
$7,000 - $10,000 |  |  | 25.0 | %
> $10,000 |  |  | 40.0 | %

As an example and considering a price of US$12,600 per metric ton (similar to the average price seen in the third quarter of 2017), the lease rate would have been equal to 19.14%.

| · | In regard to potassium chloride, the current rate of 1.8% on FOB sales shall be changed to the following structure of progressive rates based on the final sale price.

Price US$/MT KCL |  | Lease payment rate |
$0 - $300 |  |  | 3.0 | %
$300 - $400 |  |  | 7.0 | %
$400 - $500 |  |  | 10.0 | %
$500 - $600 |  |  | 15.0 | %
> $600 |  |  | 20.0 | %

| · | Similarly, the lease rates associated with the other products (lithium hydroxide, potassium sulfate and others) shall have similar changes to those described in the previous products.

| b. | SQM Salar commits to contribute (i) between US$10.8 and US$18.9 million per year to research and development efforts, (ii) between US$10 to US$15 million per year to the communities in close proximity to the Salar de Atacama, and (iii) 1.7% of total annual sales of SQM Salar to the regional development. As an example and considering annualized SQM Salar´s revenues reported in the first nine months of 2017 (approximately US$1 billion), 1.7% of sales would have been approximately US$17 million.

| c. | The authorization by CORFO to increase the production and sales of lithium products produced in the Salar de Atacama. Subject to prior authorization by CCHEN, the Agreement considers that SQM Salar will have the right to exploit, subject to compliance with other agreed conditions, process and sell during the term of the Agreement (until the end of 2030) up to 349,553 metric tons of lithium metallic equivalent in the addition to the approximately remaining 64,816 metric tons of lithium metallic equivalent from the originally authorized amount. The sum of the above amounts is equal to approximately 2.2 million metric tons of lithium carbonate equivalent.

| d. | SQM Salar shall offer part of its lithium production (up to a maximum of 25%) at preferential price to value-added producers that will potentially develop in Chile, a price based on the lowest export market price equal in each case to the weighted average FOB price calculated on the 20% lower price of the volume exported by SQM Salar during the last 6 months available.

| e. | SQM Salar shall strengthen its corporate governance, incorporating various audit, environmental control and coordination mechanisms with CORFO. For these purposes it will be necessary to modify the bylaws of SQM Salar, including among others: (i) to incorporate specific rules for the management of the company, in the form that two of the directors of SQM Salar are independent and meet the requirements established for independent directors of a public company and (ii) for the board of SQM Salar to designate a committee to monitor compliance with the Contracts and to establish the regulations that will govern this committee and its functions.

| f. | Extensive regulation regarding the return of assets upon termination of the Contracts and granting purchase options, including: (i) the restitution of the assets that Corfo made available to SQM Salar under the Contracts, (ii) a purchase option for all or part of the water rights that SQM Salar or its related parties currently own or will obtain in the future, that benefit or are necessary for the exploitation, either currently or in the future of the mining concessions included in the Contracts (the "Mining Concessions"), (iii) a free transfer to CORFO of the easements, that benefit the Mining Concessions or the project, developed by SQM Salar, excluding the mining easements constituted in the Salar del Carmen, (iv) a purchase option on the assets that SQM Salar uses as productive facilities within the Mining Concessions and assets that benefit the project and that are located within the area of the Mining Concessions and within the area of 10 kilometers from the limit of the Mining concessions, (v) a purchase option on the mining concessions that SQM Salar or its related companies currently constitute or will constitute in the future within the area of 2 kilometers from the limit of the Mining Concessions.

| g. | An option for SQM Salar to sell to CORFO the facilities that are necessary to increase the additional production and operation capacity related to the increased lithium quota. The exercise price of this option is the replacement value of the facilities including its economic depreciation.

| h. | An option for CORFO to request from SQM the evaluation of a joint project with a state company for the joint exploitation of mining property in the Salar de Maricunga. SQM commits to participate in good faith in this process, and if there is no agreement for the project after 4 years, SQM will not be obligated to continue such negotiations.

| i. | SQM, SQM Salar and SQM Potasio S.A. are prohibited to (i) sell lithium brine extracted within the Mining Concessions, (ii) alienate and obstruct in any way, and enter into any act or contract that affects the restitution of the assets indicated in letter (f) above, (iii) extract brine from its mining rights area within 10 kilometers from the limit of the Mining Concessions, (iv) extract brine from its mining rights area within 2 kilometers from the limit of Mining Concessions for a period of 15 years from the termination of the Contracts, and (v) agree with other operators of the OMA mining rights of the Salar de Atacama on the ways of operating resulting in a joint or integrated management of both production sites, therefore ensuring that SQM´s operations will always be independent without facilitating operational information, commercial strategies, information systems or common applications and/or personnel, conventions or price and other agreements that by their nature may negatively affect the lease income of CORFO.

On February 15, 2018 the Asociación Indígena Consejo de Pueblos Atacameños and other indigenous Atacameño communities lodged an appeal for legal protection against Corfo, the Company, SQM Salar and SQM Potasio S.A. to rescind the Contracts on the grounds that their provisions will deprive, disturb and threaten in an illegal and arbitrary way the constitutional rights of the appellants: the right to being equal before the law, the right to live in a pollution-free environment, the right to develop any economic activity that is not immoral, against public order or national security and the right to ownership in its different forms, by authorizing the amount of lithium metallic equivalent that can be extracted, processed and sold to be increased to 349,553 metric tonnes, such extraction being from land the appellants consider to be their ancestral property. On February 16, 2018, a number of persons belonging to the Atacameño people also lodged an appeal to rescind the contracts for alleged threats to their rights to life and physical and psychic integrity, equality before the law and the right to live in a pollution-free environment. These lawsuits are pending the consideration and subsequent resolution by the Court of Appeals in Santiago.

In a board meeting on January 24, 2018, Mrs. Joanne L. Boyes and Mr. Robert A. Kirkpatrick presented their resignation from their positions as directors of the Company. In the same session, the Board of Directors of the Company agreed to designate Mrs. Boyes as replacement, Mr. Darryl Stann who will also become a board member of the Company and a member of the Corporate Governance Committee.

On January 26, 2018, SQM and its subsidiaries SQM Salar S.A. and SQM Nitrates S.A. (the "Companies"), have reached an agreement with the Public Prosecutor to put an end to the investigation of the alleged responsibility of the Companies´ for the lack of supervision with respect to the payments to suppliers and entities that may have had links with the politically exposed persons between 2008 and 2015. This deferred prosecution agreement (suspensión condicional) has been proposed by the Public Prosecutor, accepted by the Companies and approved by the 8th Court of Santiago.

Under the deferred prosecution agreement, the Companies have not admitted responsibility in the matter subject to the investigation.

The agreement, approved by the Court, implies that the Companies must pay an aggregate amount of (i) ThUS$1,464 to the Chilean State, and (ii) ThUS$2,684 to various charitable organizations. In addition, the Companies must provide the Public Prosecutor with a report on the enhancements to their compliance program, implemented in recent years, with special emphasis on the incorporation of best practices in various jurisdictions.
