Amendments and improvements |  | Description |  | Mandatory for annual periods beginning on or after
Amendments to IFRS 9, IAS 39, IFRS 7, IFRS 4 and IFRS 16 “Reform to the referential interest rate (IBOR)- Phase 2” Published in August 2020. |  | These amendments provide certain simplifications in relation to the reform to the referential interest rates, including the replacement of a reference rate by an alternative. |  | 01-01-2021
Amendment to IFRS 16 “Lease Concessions” - Published in March 2021. |  | This amendment extends by one year the period of application of the practical case of IFRS 16 Leases (contained in the amendment to that standard published in May 2020), with the purpose of assisting lessees in accounting for COVID-19 related rental concessions. The amendment is effective for annual periods beginning on or after April 1, 2021. However, early adoption is permitted even for financial statements not authorized for issue as of March 31, 2021. |  | 01-01-2021
Management determined that the adoption of the aforementioned standards, amendments and interpretations did not significantly impact the company’s consolidated financial statements.
(b) | Standards, interpretations and amendments issued that had not become effective for financial statements beginning on January 1, 2021 and which the Company has not adopted early are as follows:
Standards and Interpretations |  | Description |  | Mandatory for annual periods beginning on or after
Amendment to IAS 1 “Presentation of financial statements” on classification of liabilities. |  | These amendments clarify that the liabilities will be classified as current or non-current depending on the rights that exist at the close of the reporting period. The classification is not affected by the expectations of the entity or the events subsequent to the report date (for example, the receipt of a waiver or noncompliance with the pact). The amendment also clarifies what IAS 1 means when referring to “liquidation” of a liability. The amendment must be applied retroactively in accordance with IAS 8. |  | 01-01-202 3
Reference to the Conceptual Framework - Amendments to IFRS 3. |  | Minor modifications were made to IFRS 3 “Definition of a Business” to update references to the conceptual framework for financial reporting without changing the requirements of business combinations. |  | 01-01-2022
Amendment to IAS 16 “Property, plant and equipment”. |  | This prohibits companies from deducting from the cost of the property any revenue received from the sale of articles produced while the company is preparing the asset for its anticipated use. The company must recognize this sales revenue and associated costs in the profit or loss for the fiscal year. |  | 01-01-2022
Amendment to IAS 37, “Provisions, contingent liabilities and contingent assets”. |  | This clarifies for onerous contracts which inevitable costs a company must include to assess whether a contract will result in a loss. |  | 01-01-2022
Annual improvements to IFRS standards, 2018-2020 cycle. The following improvements were finalized in May 2020: |  |  |  |
IFRS 9 Financial Instruments. |  | This clarifies which fees must be included in the 10% test for the derecognition of financial liabilities. |  | 01-01-2022
IFRS 16 Leases. |  | Modification of illustrative example 13 to eliminate the illustration of lessor payments in relation to improvements to rental properties, to eliminate any confusion as to the treatment of lease incentives. |  | 01-01-2022
Amendments to IAS 1: “Presentation of the Financial Statements” and IAS 8 “Accounting policies, changes in accounting estimates and errors”. |  | The amendments are intended to improve disclosures of accounting policies and to help users of financial statements distinguish between changes in accounting estimates and changes in accounting policies. |  | 01-01-2023
Amendment to IAS 12 - Deferred taxes related to assets and liabilities that arise from a single transaction. |  | These amendments require companies to recognize deferred taxes on transactions that result in equal amounts in taxable and deductible temporary differences in the initial recognition. |  | 01-01-2023
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 that the adoption of the above standards, amendments and interpretations will not have a significant impact on the Company’s financial statements.
| 2.5 | Basis of consolidation
| (a) | Subsidiaries
The Company established control as the basis of consolidation of its financial statements. The Company controls a subsidiary when it is exposed, or has rights, to variable returns from its involvement with the subsidiary and has the ability to affect those returns through its power over the subsidiary. The consolidation of a subsidiary starts when the Group controls it and it is no longer included in the consolidation when this control is lost. Subsidiaries are consolidated through a line by line method, adding items that represent assets, liabilities, income and expenses with a similar content, and eliminating operations between companies within the SQM Group. Results for dependent companies acquired or disposed of during the period are included in the consolidated accounts from the date on which control is transferred to the SQM Group or until the date when this control ends, as relevant. To account for an acquisition of a business, the Company uses the acquisition method. Under this method, the acquisition cost is the fair value of assets delivered, equity securities issued, and incurred or assumed liabilities at the date of exchange. Assets, liabilities and contingencies identifiable assumed in a business combination are measured initially at fair value at the acquisition date. For each business combination, the Company will measure the non-controlling interest of the acquiree either at fair value or as proportional share of net identifiable assets of the acquire. The following tables lists the principal subsidiaries controlled by the Group as of December 31, 2021 :

| 2.6 | Investments in associates and joint ventures
Investments in joint arrangements are classified as joint operations or joint ventures. The classification depends on the contractual rights and obligations of each investor, rather than the legal structure of the joint arrangement.
| (a) | Joint operations
The Company recognizes its direct right to the assets, liabilities, income and expenses of the joint arrangement.
| (b) | Joint ventures and investments in associates
Interests in companies over which joint control is exercised (joint ventures) or where an entity has significant influence (associates) are recognized using the equity accounting method. Significant influence is presumed when the investor owns over 20% of the investee’s share capital. The investment is recognized using this method in the statement of financial position at cost plus changes subsequent to acquisition and includes the proportional share of the associate’s equity. For these purposes, the percentage interest in the associate is used. The associated acquired goodwill is included in the investee’s book value and is not amortized. The debit or credit to the income statement reflects the proportional share of the profit or loss of the associate. Unrealized gains from transactions with joint ventures or associates are eliminated in accordance with the Company's percentage interest in such entities. Any unrealized losses are also eliminated, unless that transaction provides evidence that the transferred asset is impaired. Changes in associate’s or joint ventures equity are recognized proportionally with a charge or credit to "Other Reserves" and are classified according to their origin. The reporting dates of the associate or joint ventures, the Company and related policies are similar for equivalent transactions and events in similar circumstances. In the event that significant influence is lost, or the investment is sold, or held for sale, the equity method is suspended, not recognizing the proportional share of the gain or loss. If the resulting value under the equity method is negative, the share of profit or loss is reflected as zero in the consolidated financial statements, unless there is a commitment by the Company to restore the capital position of the Company, in which case the related risk provision and expense are recorded. Dividends received by these companies are recorded by reducing the value of the investment and are shown in cash flows from operating activities, and the proportional share of the gain or loss recognized in accordance with the equity method is included in the consolidated income statement under "Share of Gains (Losses) of Associates and Joint Ventures Accounted for Using the Equity Method''.
