ALBEMARLE CORPORATION AND SUBSIDIARIES
Notes to the Condensed Consolidated Financial Statements
(Unaudited)
NOTE 1—Basis of Presentation:
In the opinion of management, the accompanying unaudited condensed consolidated financial statements of Albemarle Corporation and our wholly-owned, majority-owned and controlled subsidiaries (collectively, “Albemarle,” “we,” “us,” “our” or “the Company”) contain all adjustments necessary for a fair statement, in all material respects, of our condensed consolidated balance sheets as of June 30, 2018 and December 31, 2017, our consolidated statements of income and consolidated statements of comprehensive income for the three-month and six-month periods ended June 30, 2018 and 2017 and our consolidated statements of changes in equity and condensed consolidated statements of cash flows for the six-month periods ended June 30, 2018 and 2017. All adjustments are of a normal and recurring nature. These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2017, which was filed with the Securities and Exchange Commission (“SEC”) on February 28, 2018. The December 31, 2017 condensed consolidated balance sheet data herein was derived from audited financial statements, but does not include all disclosures required by generally accepted accounting principles (“GAAP”) in the United States (“U.S.”). The results of operations for the three-month and six-month periods ended June 30, 2018 are not necessarily indicative of the results to be expected for the full year. Certain reclassifications have been made to the accompanying condensed consolidated financial statements and the notes thereto to conform to the current presentation.
Effective January 1, 2018, we adopted Accounting Standards Update (“ASU”) No. 2014-09, “Revenue from Contracts with Customers” and all related amendments using the modified retrospective method. There was no material impact to our results of operations or financial position upon adoption, and no adjustment was made to Retained earnings in our consolidated balance sheets because such adjustment was determined to be immaterial. In addition, new presentation requirements, including separate disclosure of net sales from sources other than customers on our consolidated statements of income and separate disclosures of contract assets or liabilities on our consolidated balance sheets, generally did not have a material impact. However, business circumstances, including the nature of customer contracts, can change and as such, we are expanding processes and controls to recognize such changes, and as necessary, consider whether any of these currently immaterial items might differ in the future.

Included in Trade accounts receivable at June 30, 2018 is approximately $558.9 million arising from contracts with customers. The remaining balance of Trade accounts receivable at June 30, 2018 primarily includes value-added taxes collected from customers on behalf of various taxing authorities. In addition, see below for a description of our updated revenue recognition accounting policy.
Revenue Recognition
Revenue is measured as the amount of consideration we expect to receive in exchange for transferring goods or providing services, and is recognized when performance obligations are satisfied under the terms of contracts with our customers. A performance obligation is deemed to be satisfied when control of the product or service is transferred to our customer. The transaction price of a contract, or the amount we expect to receive upon satisfaction of all performance obligations, is determined by reference to the contract’s terms and includes adjustments, if applicable, for any variable consideration, such as customer rebates, noncash consideration or consideration payable to the customer, although these adjustments are generally not material. Where a contract contains more than one distinct performance obligation, the transaction price is allocated to each performance obligation based on the standalone selling price of each performance obligation, although these situations do not occur frequently and are generally not built into our contracts. Any unsatisfied performance obligations are not material. Standalone selling prices are based on prices we charge to our customers, which in some cases is based on established market prices. Sales and other similar taxes collected from customers on behalf of third parties are excluded from revenue. Our payment terms are generally between 30 to 90 days, however, they vary by market factors, such as customer size, geography and competitive environment.
All of our revenue is derived from contracts with customers, and almost all of our contracts with customers contain one performance obligation for the transfer of goods where such performance obligation is satisfied at a point in time. Control of a product is deemed to be transferred to the customer upon shipment or delivery. Significant portions of our sales are sold free on board shipping point or on an equivalent basis, while delivery terms of other transactions are based upon specific contractual arrangements. Our standard terms of delivery are generally included in our contracts of sale, order confirmation documents and invoices, while the timing between shipment and delivery generally ranges between 1 and 45 days. Costs for shipping and handling activities, whether performed before or after the customer obtains control of the goods, are accounted for as fulfillment costs.

Notes to the Condensed Consolidated Financial Statements
(Unaudited)
The Company currently utilizes the following practical expedients, as permitted by Accounting Standards Codification (“ASC”) 606, Revenue from Contracts with Customers:

• | All sales and other pass-through taxes are excluded from contract value;

• | In utilizing the modified retrospective transition method, no adjustment would be necessary for contracts that do not cross over a reporting year;

• | We will not consider the possibility of a contract having a significant financing component (which would effectively attribute a portion of the sales price to interest income) unless, if at contract inception, the expected payment terms (from time of delivery or other relevant criterion) are more than one year;

• | If our right to customer payment is directly related to the value of our completed performance, we recognize revenue consistent with the invoicing right; and

• | We expense as incurred all costs of obtaining a contract incremental to any costs/compensation attributable to individual product sales/shipments for contracts where the amortization period for such costs would otherwise be one year or less.

Certain products we produce are made to our customer’s specifications where such products have no alternative use or would need significant rework costs in order to be sold to another customer. In management’s judgment, control of these arrangements is transferred to the customer at a point in time (upon shipment or delivery) and not over the time they are produced. Therefore revenue is recognized upon shipment or delivery of these products.
Costs incurred to obtain contracts with customers are not significant and are expensed immediately as the amortization period would be one year or less. When the Company incurs pre-production or other fulfillment costs in connection with an existing or specific anticipated contract and such costs are recoverable through margin or explicitly reimbursable, such costs are capitalized and amortized to Cost of goods sold on a systematic basis that is consistent with the pattern of transfer to the customer of the goods or services to which the asset relates, which is less than one year. We record bad debt expense in specific situations when we determine the customer is unable to meet its financial obligation.
NOTE 2—Divestitures:
On December 14, 2017, the Company signed a definitive agreement to sell the polyolefin catalysts and components portion of its Performance Catalyst Solutions (“PCS”) business to W.R. Grace & Co., with the sale closing on April 3, 2018. We received net cash proceeds of approximately $416.7 million and have recorded a gain of $218.7 million before income taxes in the second quarter of 2018 related to the sale of this business. The transaction includes Albemarle’s Product Development Center located in Baton Rouge, Louisiana, and operations at its Yeosu, South Korea site. The sale does not include the Company’s organometallics or curatives portion of its PCS business. The sale of the polyolefin catalysts business and components reflects the Company’s commitment to investing in the future growth of its high priority businesses and returning capital to shareholders.
In the fourth quarter of 2017, we determined that the assets held for sale criteria in accordance with ASC 360, Property, Plant and Equipment, were met for this business. As such, the assets and liabilities of this business were included in Assets held for sale and Liabilities held for sale, respectively, in the consolidated balance sheet as of December 31, 2017.

(b) | As of December 31, 2017, $3.6 million of Other intangibles, net of amortization were classified as Assets held for sale in the condensed consolidated balance sheets. See Note 2, “Divestitures,” for additional information.

NOTE 4—Foreign Exchange:
Foreign exchange transaction and revaluation losses were $1.2 million and $4.4 million for the three-month and six-month periods ended June 30, 2018, respectively, and $0.8 million and $5.7 million for the three-month and six-month periods ended June 30, 2017, respectively, and were included in Other expenses, net, in our consolidated statements of income, with the unrealized portion included in Other, net, in our condensed consolidated statements of cash flows.
NOTE 5—Income Taxes:
The effective income tax rate for the three-month and six-month periods ended June 30, 2018 was 21.5% and 19.7%, respectively, compared to 19.0% and 20.0% for the three-month and six-month periods ended June 30, 2017, respectively. The Company’s effective income tax rate fluctuates based on, among other factors, its level and location of income. The difference between the U.S. federal statutory income tax rate of 21% and our effective income tax rate for the three-month and six-month periods ended June 30, 2018 was impacted by a variety of factors, primarily stemming from the location in which income was earned. Income tax expense for the three-month and six-month period ended June 30, 2018 included discrete tax adjustments of $42.0 million for the disposition of the polyolefin catalysts and components portion of our PCS business as described in Note 2, “Divestitures,” and $8.5 million for a valuation allowance recorded due to a foreign restructuring plan, partially offset by an $8.0 million benefit for tax accounting method changes. In addition, Income tax expense for the six-month period ended June 30, 2018 included a $6.5 million benefit for adjustments related to the accounting for the U.S. Tax Cuts and Jobs Act (“TCJA”) as noted below and $7.2 million in excess tax benefits realized from stock-based compensation arrangements. The difference between the U.S. federal statutory income tax rate of 35% and our effective income tax rate for the three-month and six-month periods ended June 30, 2017 was primarily due to the impact of earnings from outside the U.S., and is mainly attributable to our share of the income of our Jordan Bromine Company Limited (“JBC”) joint venture, a Free Zones company under the laws of the Hashemite Kingdom of Jordan. In addition, Income tax expense for the six-month period ended June 30, 2017 included foreign rate changes of $13.1 million and a $5.1 million out-of-period adjustment due to changes in our deferred tax liabilities for basis differences in Chilean fixed assets, partially offset by a $9.8 million benefit from the release of valuation allowances due to a foreign restructuring plan that was initiated during the quarter and a $4.7 million reduction from the tax effects of share-based compensation awards.
In connection with the TCJA, we recorded a provisional amount of income tax expense of $429.2 million related to the one-time transition tax and income tax benefit of $62.3 million related to the remeasurement of deferred tax balances for the year ended December 31, 2017. In accordance with SEC Staff Accounting Bulletin (“SAB”) 118, the effects of the TCJA may
11

Notes to the Condensed Consolidated Financial Statements
(Unaudited)
be adjusted within a one-year measurement period from the enactment date for the items that were previously reported as provisional, or where a provisional estimate could not be made. The income tax provision for the six-month period ended June 30, 2018 reflects a discrete tax benefit of $2.8 million related to an adjustment of our estimate of the one-time transition tax and a discrete tax benefit of $3.7 million related to other provisions of the TCJA. In addition, the effective income tax rate for the three-month and six-month periods ended June 30, 2018, includes a $3.1 million and $6.1 million, respectively, net tax expense, primarily related to global intangible low-taxed income enacted by the TCJA. For the global intangible low-taxed income provisions of the TCJA, we have not yet elected an accounting policy with respect to either recognizing deferred taxes for basis differences expected to impact global intangible low-taxed income, or to record such as period costs if and when incurred. We also continue to evaluate our indefinite reinvestment assertion as a result of the TCJA. We will continue to assess forthcoming guidance and accounting interpretations on the effects of the TCJA and expect to finalize our analysis within the measurement period in accordance with the SEC guidance.
NOTE 6—Earnings Per Share:
Basic and diluted earnings per share for the three-month and six-month periods ended June 30, 2018 and 2017 are calculated as follows (in thousands, except per share amounts):

On February 23, 2018, the Company increased the regular quarterly dividend by 5% to $0.335 per share. On May 8, 2018, the Company declared a cash dividend of $0.335 per share, which was paid on July 2, 2018 to shareholders of record at the close of business as of June 15, 2018. On July 26, 2018, the Company declared a cash dividend of $0.335 per share, which is payable on October 1, 2018 to shareholders of record at the close of business as of September 14, 2018.
Under our existing Board authorized share repurchase program, the Company entered into an accelerated share repurchase (“ASR”) agreement with a financial institution on May 11, 2018. Under the ASR agreement, in the second quarter of 2018, the Company paid $250 million from available cash on hand and received and retired 2,354,133 shares of our common stock with a fair market value of $230 million, which reduced the Company’s weighted average shares outstanding for purposes of calculating basic and diluted earnings per share for the three-month and six-month periods ended June 30, 2018. The total number of shares to ultimately be delivered under the ASR agreement will be determined upon completion of the ASR agreement, which will be by the end of the third quarter of 2018, and will generally be based on the daily Rule 10b-18 volume-weighted average prices of the Company’s common stock over the term of the ASR agreement, less an agreed discount. The Company has determined that the ASR agreement meets the criteria to be accounted for as a forward contract indexed to its stock and is therefore being treated as an equity instrument. Although the ASR agreement can be settled, at the Company’s option, in cash or in shares of common stock, the Company intends to settle in shares of common stock.
No more than 15,000,000 shares can be repurchased under the Company’s authorized share repurchase program. As of June 30, 2018, there were 10,304,784 remaining shares available for repurchase under the Company’s authorized share repurchase program due to shares previously repurchased under this program to date.

Total(c) | $ | 665,522 |  |  | $ | 592,781 |

(a) | Increase primarily due to the build up of inventory in our Lithium segment resulting from increased sales, and the timing of net sales expected in the second half of our Catalysts segment.

(b) | Increase primarily due to higher forecasted production levels in the third quarter from our Catalysts segment. Included $67.0 million and $59.6 million at June 30, 2018 and December 31, 2017, respectively, of work in process related to the Lithium product category.

(c) | As of December 31, 2017, $24.7 million of Inventories were classified as Assets held for sale in the condensed consolidated balance sheets. See Note 2, “Divestitures,” for additional information.

NOTE 8—Investments:
The Company holds a 49% equity interest in Windfield Holdings Pty. Ltd. (“Windfield”), where the ownership parties share risks and benefits disproportionate to their voting interests. As a result, the Company considers Windfield to be a variable interest entity (“VIE”), however this investment is not consolidated as the Company is not the primary beneficiary. The carrying amount of our 49% equity interest in Windfield, which is our most significant VIE, was $341.7 million and $355.2 million at June 30, 2018 and December 31, 2017, respectively. The Company’s aggregate net investment in all other entities which it considers to be VIEs for which the Company is not the primary beneficiary was $8.4 million and $8.7 million at June 30, 2018 and December 31, 2017, respectively. Our unconsolidated VIEs are reported in Investments on the condensed consolidated balance sheets. The Company does not guarantee debt for, or have other financial support obligations to, these entities, and its maximum exposure to loss in connection with its continuing involvement with these entities is limited to the carrying value of its investments.
As part of the original Windfield joint venture agreement, Tianqi Lithium Corporation ("Tianqi") was granted an option to purchase from 20% to 30% of the equity interests in Rockwood Lithium GmbH, a wholly-owned German subsidiary of Albemarle, and its subsidiaries. In February 2017, Albemarle and Tianqi terminated the option agreement, and as a result, we retained 100% of the ownership interest in Rockwood Lithium GmbH and its subsidiaries. Following the termination of the option agreement, the $13.1 million fair value of the option agreement originally recorded in Noncontrolling interests was reversed and recorded as an adjustment to Additional paid-in capital.

During the first six months of 2018, we repaid a net amount of $213.3 million of commercial paper notes using cash on hand.
On June 21, 2018, we entered into a revolving, unsecured credit agreement (“2018 Credit Agreement”) to replace our revolving, unsecured credit agreement dated as of February 7, 2014, as amended. The 2018 Credit Agreement currently provides for borrowings of up to $1.0 billion and matures on June 21, 2023. Borrowings under the 2018 Credit Agreement bear interest at variable rates based on an average London inter-bank offered rate (“LIBOR”) for deposits in the relevant currency plus an applicable margin which ranges from 0.910% to 1.500%, depending on the Company’s credit rating from Standard & Poor’s Ratings Services, Moody’s Investors Services and Fitch Ratings. The applicable margin on the facility was 1.125% as of June 30, 2018. There were no borrowings outstanding under the 2018 Credit Agreement as of June 30, 2018.
The carrying value of our 1.875% Euro-denominated senior notes has been designated as an effective hedge of our net investment in certain foreign subsidiaries where the Euro serves as the functional currency, and gains or losses on the revaluation of these senior notes to our reporting currency are recorded in accumulated other comprehensive loss. During the three-month and six-month periods ended June 30, 2018, gains of $23.0 million and $8.6 million (net of income taxes), respectively, and during the three-month and six-month periods ended June 30, 2017, losses of $14.2 million and $27.9 million (net of income taxes), respectively, were recorded in accumulated other comprehensive loss in connection with the revaluation of these senior notes to our reporting currency.

Environmental remediation liabilities included discounted liabilities of $42.8 million and $28.1 million at June 30, 2018 and December 31, 2017, respectively, discounted at rates with a weighted-average of 3.7% and 3.6%, respectively, with the undiscounted amount totaling $84.7 million and $68.2 million at June 30, 2018 and December 31, 2017, respectively. For certain locations where the Company is operating groundwater monitoring and/or remediation systems, prior owners or insurers have assumed all or most of the responsibility.
The amounts recorded represent our future remediation and other anticipated environmental liabilities. These liabilities typically arise during the normal course of our operational and environmental management activities or at the time of acquisition of the site, and are based on internal analysis as well as input from outside consultants. As evaluations proceed at each relevant site, changes in risk assessment practices, remediation techniques and regulatory requirements can occur, therefore such liability estimates may be adjusted accordingly. The timing and duration of remediation activities at these sites will be determined when evaluations are completed. Although it is difficult to quantify the potential financial impact of these remediation liabilities, management estimates (based on the latest available information) that there is a reasonable possibility that future environmental remediation costs associated with our past operations, could be an additional $10 million to $25 million before income taxes, in excess of amounts already recorded.
We believe that any sum we may be required to pay in connection with environmental remediation matters in excess of the amounts recorded would likely occur over a period of time and would likely not have a material adverse effect upon our results of operations, financial condition or cash flows on a consolidated annual basis although any such sum could have a material adverse impact on our results of operations, financial condition or cash flows in a particular quarterly reporting period.
Litigation
We are involved from time to time in legal proceedings of types regarded as common in our business, including administrative or judicial proceedings seeking remediation under environmental laws, such as the federal Comprehensive Environmental Response, Compensation and Liability Act, commonly known as CERCLA or Superfund, products liability, breach of contract liability and premises liability litigation. Where appropriate, we may establish financial reserves for such proceedings. We also maintain insurance to mitigate certain of such risks. Costs for legal services are generally expensed as incurred.
Following receipt of information regarding potential improper payments being made by third party sales representatives of our Refining Solutions business, within our Catalysts segment, we promptly retained outside counsel and forensic accountants to investigate potential violations of the Company’s Code of Conduct, the Foreign Corrupt Practices Act and other potentially applicable laws. Based on this internal investigation, we have voluntarily self-reported potential issues relating to the use of third party sales representatives in our Refining Solutions business, within our Catalysts segment, to the U.S. Department of Justice (“DOJ”) and SEC, and are cooperating with the DOJ and SEC in their review of these matters. In connection with our internal investigation, we have implemented, and are continuing to implement, appropriate remedial measures.
At this time, we are unable to predict the duration, scope, result or related costs associated with any investigations by the DOJ or SEC. We also are unable to predict what, if any, action may be taken by the DOJ or SEC or what penalties or remedial actions they may seek. Any determination that our operations or activities are not in compliance with existing laws or regulations, however, could result in the imposition of fines, penalties, disgorgement, equitable relief or other losses. We do not believe, however, that any fines, penalties, disgorgement, equitable relief or other losses would have a material adverse effect on our financial condition or liquidity.
In the first quarter of 2018, a jury rendered a verdict against Albemarle in a legal matter related to certain business concluded under a 2014 sales agreement for products that Albemarle no longer manufactures. In July 2018, the court denied our motion to set aside the judgment. As a result, we have recorded an estimated accrual of $17.6 million in Other expenses, net during the six months ended June 30, 2018 and are currently evaluating our appeal options. In addition, during the second quarter of 2018, we recorded an estimated charge of $10.4 million in Other expenses, net resulting from a proposed settlement in a legal matter related to guarantees from a previously disposed business. Both matters are included in Accrued liabilities as of the balance sheet date.
Indemnities
We are indemnified by third parties in connection with certain matters related to acquired and divested businesses. Although we believe that the financial condition of those parties who may have indemnification obligations to the Company is generally sound, in the event the Company seeks indemnity under any of these agreements or through other means, there can be

no assurance that any party who may have obligations to indemnify us will adhere to their obligations and we may have to resort to legal action to enforce our rights under the indemnities.
The Company may be subject to indemnity claims relating to properties or businesses it divested, including properties or businesses of acquired businesses that were divested prior to the completion of the acquisition. In the opinion of management, and based upon information currently available, the ultimate resolution of any indemnification obligations owed to the Company or by the Company is not expected to have a material effect on the Company’s financial condition, results of operations or cash flows. The Company had approximately $25.1 million and $42.7 million at June 30, 2018 and December 31, 2017, respectively, recorded in Other noncurrent liabilities related to the indemnification of certain income and non-income tax liabilities associated with the Chemetall Surface Treatment entities sold.
Other
We have contracts with certain of our customers, which serve as guarantees on product delivery and performance according to customer specifications that can cover both shipments on an individual basis as well as blanket coverage of multiple shipments under certain customer supply contracts. The financial coverage provided by these guarantees is typically based on a percentage of net sales value.
NOTE 11—Segment Information:
In the first quarter of 2018, the PCS product category merged with our former Refining Solutions reportable segment to form a global business focused on catalysts. As a result, our three reportable segments include: (1) Lithium; (2) Bromine Specialties; and (3) Catalysts. Each segment has a dedicated team of sales, research and development, process engineering, manufacturing and sourcing, and business strategy personnel and has full accountability for improving execution through greater asset and market focus, agility and responsiveness. This business structure aligns with the markets and customers we serve through each of the segments. The structure also facilitates the continued standardization of business processes across the organization, and is consistent with the manner in which information is presently used internally by the Company’s chief operating decision maker to evaluate performance and make resource allocation decisions.
Summarized financial information concerning our reportable segments is shown in the following tables. Results for 2017 have been recast to reflect the change in segments noted above.
The “All Other” category includes only the fine chemistry services business that does not fit into any of our core businesses.
The Corporate category is not considered to be a segment and includes corporate-related items not allocated to the operating segments. Pension and OPEB service cost (which represents the benefits earned by active employees during the period) and amortization of prior service cost or benefit are allocated to the reportable segments, All Other, and Corporate, whereas the remaining components of pension and OPEB benefits cost or credit (“Non-operating pension and OPEB items”) are included in Corporate. Segment data includes intersegment transfers of raw materials at cost and allocations for certain corporate costs.
The Company’s chief operating decision maker uses adjusted EBITDA (as defined below) to assess the ongoing performance of the Company’s business segments and to allocate resources. The Company defines adjusted EBITDA as earnings before interest, taxes, depreciation and amortization, as adjusted on a consistent basis for certain non-recurring or unusual items in a balanced manner and on a segment basis. These non-recurring or unusual items may include acquisition and integration related costs, utilization of inventory markup, gains or losses on sales of businesses, restructuring charges, facility divestiture charges, non-operating pension and OPEB items and other significant non-recurring items. In addition, management uses adjusted EBITDA for business planning purposes and as a significant component in the calculation of performance-based compensation for management and other employees. The Company has reported adjusted EBITDA because management believes it provides transparency to investors and enables period-to-period comparability of financial performance. Adjusted EBITDA is a financial measure that is not required by, or presented in accordance with, U.S. GAAP. Adjusted EBITDA should not be considered as an alternative to Net income attributable to Albemarle Corporation, the most directly comparable financial measure calculated and reported in accordance with U.S. GAAP, or any other financial measure reported in accordance with U.S. GAAP.

NOTE 12—Pension Plans and Other Postretirement Benefits:
The components of pension and postretirement benefits cost (credit) for the three-month and six-month periods ended June 30, 2018 and 2017 were as follows (in thousands):

| Three Months Ended June 30, |  | Six Months Ended June 30,

As a result of the adoption of new accounting guidance effective January 1, 2018, on a retrospective basis, all components of net benefit cost (credit), other than service cost, are to be shown outside of operations on the consolidated statements of income. We recast these components of net benefit cost (credit), which resulted in a reduction of $0.1 million and $0.3 million in Cost of goods sold, respectively, and $0.9 million and $1.8 million in Selling, general and administrative expenses, respectively, with an offsetting increase of $1.0 million and $2.1 million in Other expenses, net, respectively, for the three-month and six-month periods ended June 30, 2017. There was no impact to Net income attributable to Albemarle Corporation.
During the three-month and six-month periods ended June 30, 2018, we made contributions of $2.8 million and $5.9 million, respectively, to our qualified and nonqualified pension plans. During the three-month and six-month periods ended June 30, 2017, we made contributions of $2.7 million and $5.1 million, respectively, to our qualified and nonqualified pension plans.

Effective July 1, 2016, the Pensionskasse Dynamit Nobel Versicherungsverein auf Gegenseitigkeit, Troisdorf multiemployer plan is subject to a financial improvement plan which expires on December 31, 2022, with the final contribution in the second quarter of 2023. This financial improvement plan calls for increased capital reserves to avoid future underfunding risk. During the three-month and six-month periods ended June 30, 2017, we made contributions for our employees covered under this plan of approximately $2.0 million, recorded in Selling, general and administrative expenses, as a result of this financial improvement plan. In addition, during the three-month and six-month periods ended June 30, 2017, we made contributions relating to this financial improvement plan to indemnify previously divested businesses of approximately $2.9 million, recorded in Other expenses, net. There were no contributions made under the financial improvement plan during the three-month and six-month periods ended June 30, 2018.
NOTE 13—Fair Value of Financial Instruments:
In assessing the fair value of financial instruments, we use methods and assumptions that are based on market conditions and other risk factors existing at the time of assessment. Fair value information for our financial instruments is as follows:
Long-Term Debt—the fair values of our senior notes are estimated using Level 1 inputs and account for the difference between the recorded amount and fair value of our long-term debt. The carrying value of our remaining long-term debt reported in the accompanying condensed consolidated balance sheets approximates fair value as substantially all of such debt bears interest based on prevailing variable market rates currently available in the countries in which we have borrowings.

| June 30, 2018 |  | December 31, 2017
| Recorded Amount |  | Fair Value |  | Recorded Amount |  | Fair Value
| (In thousands)
Long-term debt | $ | 1,622,762 |  |  | $ | 1,674,541 |  |  | $ | 1,845,309 |  |  | $ | 1,949,638 |

Foreign Currency Forward Contracts—we enter into foreign currency forward contracts in connection with our risk management strategies in an attempt to minimize the financial impact of changes in foreign currency exchange rates. These derivative financial instruments are used to manage risk and are not used for trading or other speculative purposes. The fair values of our foreign currency forward contracts are estimated based on current settlement values. At June 30, 2018 and December 31, 2017, we had outstanding foreign currency forward contracts with notional values totaling $493.1 million and $357.4 million, respectively. Our foreign currency forward contracts outstanding at June 30, 2018 and December 31, 2017 were not designated as hedging instruments under ASC 815, Derivatives and Hedging. At June 30, 2018, $0.2 million was included in Other accounts receivable associated with the fair value of our foreign currency forward contracts, and at December 31, 2017, $5.0 million was included in Accrued expenses associated with the fair value of our foreign currency forward contracts.
Gains and losses on foreign currency forward contracts are recognized in Other expenses, net; further, fluctuations in the value of these contracts are generally expected to be offset by changes in the value of the underlying exposures being hedged, which are also reported in Other expenses, net. For the three-month and six-month periods ended June 30, 2018, we recognized losses of $17.6 million and $12.8 million, respectively, in Other expenses, net, in our consolidated statements of income related to the change in fair value of our foreign currency forward contracts. For the three-month and six-month periods ended June 30, 2017, we recognized gains of $3.7 million and $8.2 million, respectively, in Other expenses, net, in our consolidated statements of income related to the change in the fair value of our foreign currency forward contracts. Also, for the six-month periods ended June 30, 2018 and 2017, we recorded losses (gains) of $12.8 million and ($8.2) million, respectively, related to the change in the fair value of our foreign currency forward contracts, and net cash (settlements) receipts of ($18.0) million and $7.7 million, respectively, in Other, net, in our condensed consolidated statements of cash flows.
The counterparties to our foreign currency forward contracts are major financial institutions with which we generally have other financial relationships. We are exposed to credit loss in the event of nonperformance by these counterparties. However, we do not anticipate nonperformance by the counterparties.

NOTE 14—Fair Value Measurement:
Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price). The inputs used to measure fair value are classified into the following hierarchy:

Level 1 | Unadjusted quoted prices in active markets for identical assets or liabilities
Level 2 | Unadjusted quoted prices in active markets for similar assets or liabilities, or unadjusted quoted prices for identical or similar assets or liabilities in markets that are not active, or inputs other than quoted prices that are observable for the asset or liability
Level 3 | Unobservable inputs for the asset or liability

We endeavor to utilize the best available information in measuring fair value. Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. Transfers between levels of the fair value hierarchy are deemed to have occurred on the date of the event or change in circumstance that caused the transfer. There were no transfers between Levels 1 and 2 during the six-month period ended June 30, 2018. The following tables set forth our financial assets and liabilities that were accounted for at fair value on a recurring basis as of June 30, 2018 and December 31, 2017 (in thousands):

(a) | We maintain an Executive Deferred Compensation Plan (“EDCP”) that was adopted in 2001 and subsequently amended. The purpose of the EDCP is to provide current tax planning opportunities as well as supplemental funds upon the retirement or death of certain of our employees. The EDCP is intended to aid in attracting and retaining employees of exceptional ability by providing them with these benefits. We also maintain a Benefit Protection Trust (the “Trust”) that was created to provide a source of funds to assist in meeting the obligations of the EDCP, subject to the claims of our creditors in the event of our insolvency. Assets of the Trust are consolidated in accordance with authoritative guidance. The assets of the Trust consist primarily of mutual fund investments (which are accounted for as trading securities and are marked-to-market on a monthly basis through the consolidated statements of income) and cash and cash equivalents. As such, these assets and obligations are classified within Level 1.

(b) | Primarily consists of private equity securities classified as available-for-sale and are reported in Investments in the condensed consolidated balance sheets. The changes in fair value are reported in Other expenses, net, in our consolidated statements of income.

(c) | Holdings in certain private equity securities are measured at fair value using the net asset value per share (or its equivalent) practical expedient and have not been categorized in the fair value hierarchy.

(d) | As a result of our global operating and financing activities, we are exposed to market risks from changes in foreign currency exchange rates, which may adversely affect our operating results and financial position. When deemed appropriate, we minimize our risks from foreign currency exchange rate fluctuations through the use of foreign currency forward contracts. Unless otherwise noted, these derivative financial instruments are not designated as hedging instruments under ASC 815, Derivatives and Hedging. The foreign currency forward contracts are valued using broker quotations or market transactions in either the listed or over-the-counter markets. As such, these derivative instruments are classified within Level 2.

NOTE 18—Recently Issued Accounting Pronouncements:
In May 2014, the Financial Accounting Standards Board (“FASB”) issued accounting guidance designed to enhance comparability of revenue recognition practices across entities, industries, jurisdictions and capital markets. The core principle of the guidance is that revenue recognized from a transaction or event that arises from a contract with a customer should reflect the consideration to which an entity expects to be entitled in exchange for goods or services provided. To achieve that core principle the new guidance sets forth a five-step revenue recognition model that will need to be applied consistently to all contracts with customers, except those that are within the scope of other topics in the ASC. Also required are new disclosures to help users of financial statements better understand the nature, amount, timing and uncertainty of revenues and cash flows from contracts with customers. The new disclosures include qualitative and quantitative information about contracts with customers, significant judgments made in applying the revenue guidance, and assets recognized related to the costs to obtain or fulfill a contract. During 2016, the FASB issued amendments to this new guidance that provides clarification, technical corrections and practical expedients. Topics of potential relevance to the Company include principal versus agent considerations, collectability, presentation of sales tax from customers, contract modifications at transition and accounting transition. These new requirements became effective on January 1, 2018 and did not have a material impact on our condensed consolidated financial statements. We adopted the new standard using the modified retrospective method. We have implemented appropriate changes to the business processes, controls and control activities to support recognition, presentation and disclosure under the new standard for the first quarter of 2018, however, we have not made any significant changes to our existing systems as a result of this new standard.
In February 2016, the FASB issued accounting guidance that requires assets and liabilities arising from leases to be recorded on the balance sheet. Additional disclosures are required regarding the amount, timing, and uncertainty of cash flows from leases. This new guidance will be effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, and is to be applied using a modified retrospective approach. Early adoption is permitted. In July 2018, the FASB issued an amendment which would allow entities to initially apply this new standard at the adoption date and recognize a cumulative effect adjustment to the the opening balance of retained earnings. The Company expects to adopt this standard using this transition method. We have made significant progress in evaluating our existing lease contracts and accounting policies to determine the impact this standard will have on the condensed consolidated financial statements and related disclosures. The implementation of this standard will result in the addition of right-of-use assets and lease liabilities on our balance sheet, however, we have not determined the materiality at this time. In addition, we are in the process of reviewing the impact of this standard on our current business processes and are making progress on implementing changes to and controls to support recognition and disclosure under this new standard.
In October 2016, the FASB issued accounting guidance that eliminated the deferral of tax effects of intra-entity asset transfers other than inventory. As a result, the tax expense from the intercompany sale of assets, other than inventory, and associated changes to deferred taxes will be recognized when the sale occurs even though the pre-tax effects of the transaction have not been recognized as they are eliminated in consolidation. This guidance was effective using the modified retrospective method as of January 1, 2018, which resulted in a $11.2 million cumulative adjustment to decrease Retained earnings and is not reflected in periods prior to this date.
In November 2016, the FASB issued accounti ng guidance that requires restricted cash and restricted cash equivalents to be included with cash and cash equivalents when reconciling the beginning and end of period total amounts shown on the statement of cash flows. This guidance became effective on January 1, 2018 and did not have a significant impact on our financial statements.
In January 2017, the FASB issued accounting guidance to clarify the definition of a business for determining whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. This guidance became effective on January 1, 2018 and did not have a significant impact on our financial statements.
In January 2017, the FASB issued accounting guidance to simplify the accounting for goodwill imp airment. The guidance removes Step 2 of the goodwill impairment test, which requires a reporting unit to calculate the implied fair value of goodwill by assigning the fair value of a reporting unit to all of its assets and liabilities as if that reporting unit has been acquired in a business combination. A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. All other goodwill impairment guidance will remain unchanged. Entities will continue to have the option to perform a qualitative assessment to determine if a quantitative impairment test is necessary. This guidance will be effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years, and is to be applied on a prospective basis. Early adoption is permitted for goodwill impairment tests performed after January 1, 2017. We do not expect this guidance to have a significant impact on our financial statements.

In March 2017, the FASB issued accounting guidance that changes the presentation of net periodic pension and postretirement benefit cost (“net benefit cost”) in the income statement. This new guidance requires service cost to be presented as part of operating income (expense) and all other components of net benefit cost are to be shown outside of operations. This guidance became effective on January 1, 2018 and did not have a significant impact on our financial statements. The prior year consolidated statements of income have been recast to conform to the current presentation required by this guidance. See Note 12, “Pension Plans and Other Postretirement Benefits,” for additional details.
In May 2017, the FASB issued accounting guidance to clarify when to account for a change to the terms or conditions of a share-based payment award as a modification. Under the new guidance, modification accounting is required only if the fair value, the vesting conditions, or the classification of the award (as equity or liability) changes as a result of the change in terms or conditions. This new guidance became effective on January 1, 2018 and did not have a significant impact on our financial statements.
In August 2017, the FASB issued accounting guidance to better align an entity’s risk management activities with hedge accounting, simplify the application of hedge accounting, and increase transparency as to the scope and results of hedging programs. This guidance will make more financial and nonfinancial hedging strategies eligible for hedge accounting. It also amends the presentation and disclosure requirements and changes how companies assess effectiveness. This new guidance will be effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, and is to be applied on a prospective basis. Early adoption is permitted. We currently do not expect this guidance to have a significant impact on our financial statements.
In February 2018, the FASB issued accounting guidance that will give companies the option to reclassify stranded tax effects caused by the TCJA from accumulated other comprehensive income to retained earnings. This new guidance will be effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. Entities will have the option to apply this guidance retrospectively or to record the reclassification as of the beginning of the period of adoption. We are currently assessing the impact of this new guidance on our financial statements. In March 2018, the FASB issued additional guidance pursuant to the issuance of SAB 118, that provides clarification for a company’s ability to comply with the accounting requirements for the income tax effects of the TCJA in the period of enactment, effective immediately. SAB 118 allows disclosure that timely determination of some or all of the income tax effects from the TCJA are incomplete by the due date of the financial statements and if possible to provide a reasonable estimate. We have accounted for the tax effects of the TCJA under the guidance of SAB 118, on a provisional basis. Our accounting for certain income tax effects is incomplete, but we have determined reasonable estimates for those effects and have recorded provisional amounts in our condensed consolidated financial statements.

Overview
We are a leading global developer, manufacturer and marketer of highly-engineered specialty chemicals that are designed to meet our customers’ needs across a diverse range of end markets. The end markets we serve include energy storage, petroleum refining, consumer electronics, construction, automotive, lubricants, pharmaceuticals, crop protection and custom chemistry services. We believe that our commercial and geographic diversity, technical expertise, innovative capability, flexible, low-cost global manufacturing base, experienced management team and strategic focus on our core base technologies will enable us to maintain leading market positions in those areas of the specialty chemicals industry in which we operate.
Secular trends favorably impacting demand within the end markets that we serve combined with our diverse product portfolio, broad geographic presence and customer-focused solutions will continue to be key drivers of our future earnings growth. We continue to build upon our existing green solutions portfolio and our ongoing mission to provide innovative, yet commercially viable, clean energy products and services to the marketplace. We believe our disciplined cost reduction efforts and ongoing productivity improvements, among other factors, position us well to take advantage of strengthening economic conditions as they occur, while softening the negative impact of the current challenging global economic environment.
Second Quarter 2018
During the second quarter of 2018:

• | On April 3, 2018, we closed the sale of the polyolefin catalysts and components portion of the Performance Catalyst Solutions (“PCS”) business for net cash proceeds of approximately $416.7 million and recorded a gain of $218.7 million before income taxes related to the sale of this business.

• | We entered into a $250 million accelerated share repurchase (“ASR”) agreement, receiving and retiring 2,354,133 shares of our common stock pursuant to the terms of the ASR agreement and our share repurchase program. This ASR agreement is expected to be completed in the third quarter of 2018.

• | We entered into a revolving, unsecured credit agreement that provides for borrowings of up to $1.0 billion and matures on June 21, 2023 to replace our existing revolving, unsecured credit agreement.

• | We announced our exclusive collaboration with DuPont as the primary hydroprocessing catalyst manufacturer for the DuPont™ IsoTherming® hydroprocessing technology, making clean fuels production more cost efficient for refiners. IsoTherming® is an innovative hydroprocessing technology that can lower capital and operational costs.

• | Our board of directors declared a quarterly dividend of $0.335 per share on May 8, 2018, which was paid on July 2, 2018 to shareholders of record at the close of business as of June 15, 2018.

• | Our net sales for the quarter were $853.9 million, up 16% from net sales of $737.3 million in the second quarter of 2017.

• | Earnings per share were $2.73 (on a diluted basis), an increase from second quarter 2017 results of $0.92 per diluted share.

• | Cash provided by operating activities was $102.3 million in the second quarter of 2018.

Outlook
Effective January 1, 2018, the PCS product category merged with our former Refining Solutions reportable segment to form a global business focused on catalysts. As a result, our three reportable segments include Lithium, Bromine Specialties and Catalysts. Each segment has a dedicated team of sales, research and development, process engineering, manufacturing and sourcing, and business strategy personnel and has full accountability for improving execution through greater asset and market focus, agility and responsiveness. We expect this change to provide further clarity into the performance of each business.
The current global business environment presents a diverse set of opportunities and challenges in the markets we serve. In particular, the market for lithium battery and energy storage continues to accelerate, providing the opportunity to continue to develop high quality and innovative products while managing the high cost of expanding capacity. The other markets we serve continue to present various opportunities for value and growth as we have positioned ourselves to manage the impact on our business of changing global conditions, such as slow and uneven global growth, currency exchange volatility, crude oil price fluctuation, a dynamic pricing environment, an ever-changing landscape in electronics, the continuous need for cutting edge catalysts and technology by our refinery customers and increasingly stringent environmental standards. Amidst these dynamics, we believe our business fundamentals are sound and that we are strategically well-positioned as we remain focused on increasing sales volumes, optimizing and improving the value of our portfolio primarily through pricing and product development, managing costs and delivering value to our customers and shareholders. We believe that our businesses remain well-positioned to capitalize on new business opportunities and long-term trends driving growth within our end markets and to respond quickly to changes in economic conditions in these markets.
Lithium: We expect continued strong year over year growth for the remainder of 2018 in Lithium, led by continued strong demand in battery-grade applications, price improvement and increased conversion capacity.
On a longer term basis, we believe that demand for lithium will continue to grow as new applications for lithium power continue to be developed and the use of plug-in hybrid electric vehicles and battery electric vehicles escalates, against a favorable backdrop of steadily declining electric battery costs, increasing electric battery performance and constructive global public policy toward acceptance of e-mobility/renewables. Our long-term outlook is also bolstered by our successful negotiation of long-term supply agreements with a number of strategic customers, reflecting our standing as a preferred global lithium partner due to our scale, access to geographically diverse, low cost resources and long-term execution track record.
Bromine Specialties: We expect to see continued modest growth on net sales and profitability in 2018, due to healthy demand and pricing for our flame retardants and other derivatives. However, with sustained low oil prices, we expect stable, albeit low, drilling completion fluid demand throughout the year. While it is possible oil prices could rebound some in 2018, the short-term impact will be to increase raw material costs. Offshore well completions lag oil pricing, so any benefit in completion fluid volumes would likely extend into 2019.
On a longer term basis, we continue to believe that improving global standards of living, widespread digitization, increasing demand for data management capacity and the potential for increasingly stringent fire safety regulations in developing markets are likely to drive continued demand for fire safety products. Absent an increase in regulatory pressure on offshore drilling, we would expect this business to follow a long-term growth trajectory once oil prices recover from recent levels as we expect that deep water drilling will continue to increase around the world. We are focused on profitably growing our globally competitive bromine and derivatives production network to serve all major bromine consuming products and

markets. We believe the global supply/demand gap could tighten as demand for existing and possible new uses of bromine expands over time. The combination of solid, long-term business fundamentals, with our strong cost position, product innovations and effective management of raw material costs will enable us to manage our business through end market challenges and to capitalize on opportunities that are expected with favorable market trends in select end markets.
Catalysts: We expected to see continued headwinds from rising raw material costs in both our Clean Fuels Technologies (“CFT”) and Fluid Catalytic Cracking (“FCC”) businesses, similar to 2017. In our PCS division, we expect our curatives business to be negatively impacted by a temporary supply shortage of a key raw material. We also anticipate that the profitability in our organometallics business will stabilize with productivity gains and increased volumes due to market demand.
On a longer term basis, we believe increased global demand for transportation fuels, new refinery start-ups and ongoing adoption of cleaner fuels will be the primary drivers of growth in our Catalysts business. We believe delivering superior end-use performance continues to be the most effective way to create sustainable value in the refinery catalysts industry. We believe our technologies continue to provide significant performance and financial benefits to refiners challenged to meet tighter regulations around the world, including those managing new contaminants present in North America tight oil, and those in the Middle East and Asia seeking to use heavier feedstock while pushing for higher propylene yields. Longer term, we believe that the global crude supply will get heavier and more sour, a trend that bodes well for our catalysts portfolio. With superior technology and production capacities, and expected growth in end market demand, we believe that Catalysts remains well-positioned for the future. In PCS, we expect growth in our organometallic business due to growing global demand for plastics driven by rising standards of living and infrastructure spending.
On April 3, 2018, we completed the sale of the polyolefin catalysts and components portion of the PCS business to W.R. Grace & Co. for net cash proceeds of approximately $416.7 million.
All Other: The fine chemistry services business will continue to be reported outside the Company’s reportable segments as it does not fit in the Company’s core businesses. We expect the near future to be a challenge for this business due to a challenging agriculture industry environment, as well as customer order timing in pharmaceuticals, however, we continue to work to reinvigorate the pipeline of new products and services to these markets.
Corporate: We continue to focus on cash generation, working capital management and process efficiencies. We expect our global effective tax rate for 2018 to be approximately 23.9%; however, our rate will vary based on the locales in which income is actually earned and remains subject to potential volatility from changing legislation in the U.S., including the U.S. Tax Cuts and Jobs Act (“TCJA”), and other tax jurisdictions.
In the first quarter of 2018, we increased our quarterly dividend rate to $0.335 per share. During the three-month and six-month periods ended June 30, 2018, we received and retired approximately 2.4 million shares of our common stock under our share repurchase program and the ASR agreement. The total number of shares to ultimately be delivered under the ASR agreement will be determined upon completion of the ASR agreement, which will be by the end of the third quarter of 2018. In addition, following the completion of this ASR agreement, we may periodically repurchase shares in the future on an opportunistic basis as approved by our share repurchase program.
We remain committed to evaluating the merits of any opportunities that may arise for acquisitions or other business development activities that will complement our business footprint.

Net Sales
For the three-month period ended June 30, 2018, we recorded net sales of $853.9 million, an increase of $116.6 million, or 16%, compared to net sales of $737.3 million for the three-month period ended June 30, 2017. Net sales increased across all three reportable segments due to $86.7 million of higher volumes, $40.0 million of favorable pricing impacts and $15.6 million of favorable currency exchange. Partially offsetting this is $25.7 million related to the divestiture of the polyolefin catalyst and components portion of the PCS business.
Gross Profit
For the three-month period ended June 30, 2018, our gross profit increased $39.4 million, or 14%, from the corresponding 2017 period. Gross profit in 2017 included a $11.9 million charge related to the markup of inventory purchased as part of the Jiangxi Jiangli New Materials Science and Technology Co. Ltd. (“Jiangli New Materials”) acquisition and $9.8 million of gross profit related to the polyolefin catalyst and components business, which was divested in 2018. Excluding the impact of these items, gross profit increased by $37.3 million, or 14%, primarily due to $40.0 million in favorable price impacts and higher volumes across all three reportable segments, more than offsetting higher costs related to Lithium royalty payments and material costs. Overall, these factors contributed to a gross profit margin for the three-month period ended June 30, 2018 of 36.5%, down from 36.9% in the corresponding period in 2017.

Selling, General and Administrative Expenses
For the three-month period ended June 30, 2018, our selling, general and administrative (“SG&A”) expenses increased $7.1 million, or 6%, from the three-month period ended June 30, 2017. The three-month period ended June 30, 2018 included $0.9 million of higher acquisition and integration related costs from various significant projects compared to the corresponding 2017 period and a $15.0 million contribution to the Albemarle Fund to further support the communities in which we operate. In addition, the three-month period ended June 30, 2017 included $4.2 million of restructuring costs related to several locations and $2.0 million of multiemployer plan financial improvement plan shortfall contributions for our employees. Excluding the impact of these charges, SG&A expenses decreased $2.6 million, primarily due to slightly lower Corporate spend and flat Lithium growth spending. As a percentage of net sales, SG&A expenses were 14.5% for the three-month period ended June 30, 2018, compared to 15.8% for the corresponding period in 2017.
Research and Development Expenses
For the three-month period ended June 30, 2018, our research and development (“R&D”) expenses decreased $1.3 million, or 7%, from the three-month period ended June 30, 2017. As a percentage of net sales, R&D expenses were 1.9% and 2.4% for the three-month periods ended June 30, 2018 and 2017, respectively.
Gain on Sale of Business
In the second quarter of 2018, we closed the sale of the polyolefin catalysts and components portion of the PCS business and recorded a gain before income taxes of $218.7 million.
Interest and Financing Expenses
Interest and financing expenses for the three-month period ended June 30, 2018 decreased $1.3 million to $13.3 million from the corresponding 2017 period primarily due the impact of higher capitalized interest from increased capital expenditures and reduced commercial paper notes during 2018.
Other Expenses, Net
Other expenses, net, for the three-month period ended June 30, 2018 was $5.2 million compared to $1.7 million for the corresponding 2017 period. During the three-month period ended June 30, 2018, we recorded a $10.4 million legal accrual relating to a previously disposed business. During the three-month period ended June 30, 2017, we recorded $6.1 million of charges related to previously divested businesses. The remaining change was primarily due to an increase in foreign exchange losses totaling $0.5 million, partially offset by an increase in interest income.
Income Tax Expense
The effective income tax rate for the second quarter of 2018 was 21.5% compared to 19.0% for the second quarter of 2017. The difference between the U.S. federal statutory income tax rate of 21% and our effective income tax rate for the three-months ended June 30, 2018 was impacted by a variety of factors, primarily stemming from the location in which income was earned. The difference between the U.S. federal statutory income tax rate of 35% and our effective income tax rate for the three-months ended June 30, 2017 was primarily due to the impact of earnings from outside the U.S., and is mainly attributable to our share of the income of our Jordan Bromine Company Limited (“JBC”) joint venture, a Free Zones company under the laws of the Hashemite Kingdom of Jordan. The increase in the effective tax rate for the three-month period ended June 30, 2018 compared to the same period last year, was driven by a variety of factors, primarily stemming from a change in the geographic mix of earnings.
Equity in Net Income of Unconsolidated Investments
Equity in net income of unconsolidated investments was $19.0 million for the three-month period ended June 30, 2018 compared to $15.0 million in the same period last year. This increase of $4.0 million was primarily due to an increase in equity income in our Catalyst segment and in our Lithium joint venture, Windfield Holdings Pty. Ltd.
Net Income Attributable to Noncontrolling Interests
For the three-month period ended June 30, 2018, net income attributable to noncontrolling interests was $8.2 million compared to $10.4 million in the same period last year. This decrease of $2.2 million was primarily due to a decrease in consolidated income related to our JBC joint venture from lower sales volumes in the quarter related to the installation of additional production capacity in the current year.
Net Income Attributable to Albemarle Corporation
Net income attributable to Albemarle Corporation increased to $302.5 million in the three-month period ended June 30, 2018, from $103.3 million in the three-month period ended June 30, 2017. The increase is primarily due to the after-tax gain of $176.6 million related to the sale of the polyolefin catalysts and components portion of the PCS business as well as favorable

pricing and volume impacts across all reportable segments. This was partially offset by a $15.0 million charitable contribution to the Albemarle Foundation, a $10.4 million legal accrual relating to a previously disposed business and a higher effective tax rate in 2018.
Other Comprehensive (Loss) Income, Net of Tax
Total other comprehensive (loss) income, after income taxes, was ($127.2) million for the three-month period ended June 30, 2018 compared to $50.4 million for the corresponding period in 2017. The majority of these amounts are the result of translating our foreign subsidiary financial statements from their local currencies to U.S. Dollars. In the 2018 period, other comprehensive loss from foreign currency translation adjustments was $150.9 million, primarily as a result of unfavorable movements in the Euro of approximately $110 million, the Chinese Renminbi of approximately $14 million, the Brazilian Real of approximately $12 million and a net unfavorable variance in various other currencies totaling approximately $15 million. Also included in total other comprehensive loss for the 2018 period is income of $23.0 million in connection with the revaluation of our Euro-based 1.875% Senior notes which have been designated as a hedge of our net investment in foreign operations. In the 2017 period, other comprehensive income from foreign currency translation adjustments was $64.1 million, mainly as a result of favorable movements in the Euro of approximately $67 million and the Chinese Renminbi of approximately $4 million, partially offset by unfavorable movements in the Brazilian Real of approximately $3 million and the Korean Won of approximately $3 million. Also included in total other comprehensive income for the 2017 period is a loss of $14.2 million in connection with the revaluation of our Euro-based 1.875% Senior notes which have been designated as a hedge of our net investment in foreign operations.
Segment Information Overview. We have identified three reportable segments according to the nature and economic characteristics of our products as well as the manner in which the information is used internally by the Company’s chief operating decision maker to evaluate performance and make resource allocation decisions. Our reportable business segments consist of: (1) Lithium, (2) Bromine Specialties and (3) Catalysts.
Summarized financial information concerning our reportable segments is shown in the following tables. Results for 2017 have been recast to reflect the change in segments previously noted. The “All Other” category includes only the fine chemistry services business, that does not fit into any of our core businesses.
The Corporate category is not considered to be a segment and includes corporate-related items not allocated to the operating segments. Pension and OPEB service cost (which represents the benefits earned by active employees during the period) and amortization of prior service cost or benefit are allocated to the reportable segments, All Other, and Corporate, whereas the remaining components of pension and OPEB benefits cost or credit (“Non-operating pension and OPEB items”) are included in Corporate. Segment data includes intersegment transfers of raw materials at cost and allocations for certain corporate costs.
The Company’s chief operating decision maker uses adjusted EBITDA (as defined below) to assess the ongoing performance of the Company’s business segments and to allocate resources. The Company defines adjusted EBITDA as earnings before interest, taxes, depreciation and amortization, as adjusted on a consistent basis for certain non-recurring or unusual items in a balanced manner and on a segment basis. These non-recurring or unusual items may include acquisition and integration related costs, utilization of inventory markup, gains or losses on sales of businesses, restructuring charges, facility divestiture charges, non-operating pension and OPEB items and other significant non-recurring items. In addition, management uses adjusted EBITDA for business planning purposes and as a significant component in the calculation of performance-based compensation for management and other employees. The Company has reported adjusted EBITDA because management believes it provides transparency to investors and enables period-to-period comparability of financial performance. Adjusted EBITDA is a financial measure that is not required by, or presented in accordance with, U.S. GAAP. Adjusted EBITDA should not be considered as an alternative to Net income attributable to Albemarle Corporation, the most directly comparable financial measure calculated and reported in accordance with U.S. GAAP, or any other financial measure reported in accordance with U.S. GAAP.

(c) | Included in Other expenses, net, is a $10.4 million accrual resulting from a proposed settlement in a legal matter related to guarantees from a previously disposed business.

(d) | Included in Selling, general and administrative expenses is a charitable contribution, using a portion of the proceeds received from the sale of the polyolefin catalysts and components portion of the PCS business, to the Albemarle Foundation, a non-profit organization that sponsors grants, health and social projects, educational initiatives, disaster relief, matching gift programs, scholarships and other charitable initiatives in locations where our employees live and operate. This contribution is in addition to the normal annual contribution made to the Albemarle Foundation by the Company, and is significant in size and nature in that it is intended to provide more long-term benefits in the communities where we live and operate.

(e) | Included in Other expenses, net, is $1.2 million related to the revision of previously recorded expenses of disposed businesses.

(f) | In connection with the acquisition of Jiangli New Materials, the Company valued inventory purchased from Jiangli New Materials at fair value, which resulted in a markup of the underlying net book value of the inventory totaling approximately $23.1 million. The inventory markup was expensed over the estimated remaining selling period. For the three-month period ended June 30, 2017, $11.9 million was included in Cost of goods sold related to the utilization of the inventory markup.

(g) | During 2017, we initiated actions to reduce costs at several locations. Based on these restructuring plans, we have recorded expenses of $4.2 million in Selling, general and administrative expenses in the three-month period ended June 30, 2017, related to restructuring costs. The unpaid balance is recorded in Accrued expenses at June 30, 2018, with the expectation that the majority of these plans will be completed by the end of 2018.

Lithium
Lithium segment net sales for the three-month period ended June 30, 2018 were $317.6 million, up $73.7 million, or 30%, compared to the corresponding period of 2017. The increase was primarily driven by $36.7 million of higher volume and $29.3 million of favorable pricing due to strong demand, which continues to drive investment in new capacity, and $7.7 million of favorable currency translation primarily driven by the weaker U.S. Dollar against the Euro. Adjusted EBITDA for Lithium was up 23%, or $26.4 million, to $141.6 million for the three-month period ended June 30, 2018, compared to the corresponding period of 2017, primarily due to favorable pricing, higher sales volumes and $0.8 million of favorable currency translation, partially offset by higher royalty payments.
Bromine Specialties
Bromine Specialties segment net sales for the three-month period ended June 30, 2018 were $220.5 million, up $16.6 million, or 8%, compared to the corresponding period of 2017. The increase was primarily driven by $6.8 million in favorable pricing and $6.7 million of higher volume driven by continued strong demand in flame retardants, bromine and other derivatives, and $3.1 million of favorable currency translation driven by the weaker U.S. Dollar against the Euro. Adjusted EBITDA for Bromine Specialties was up 12%, or $7.3 million, to $69.4 million for the three-month period ended June 30, 2018, compared to the corresponding period of 2017. This increase was primarily due to favorable pricing across most products and $2.7 million of favorable currency translation related to the Euro, more than offsetting the impact of higher raw material pricing and production costs.
Catalysts
Catalysts segment net sales for the three-month period ended June 30, 2018 were $285.0 million, an increase of $26.7 million, or 10%, compared to the corresponding period of 2017. This increase was primarily due to $42.4 million of increased volumes in CFT, FCC and PCS, $5.2 million of favorable price impacts due to pass through of higher metals costs and $4.8 million of favorable currency translation driven by the weaker U.S. Dollar against the Euro. Partially offsetting this was $25.7 million related to the divestiture of polyolefin catalyst and components portion of the PCS business. Catalysts adjusted EBITDA increased 11%, or $7.7 million, to $75.1 million for the three-month period ended June 30, 2018 in comparison to the corresponding period of 2017. This increase was primarily due to higher volume and favorable pricing more than offsetting higher metals material costs and the $9.8 million impact related to the polyolefin catalyst and components divestiture.
All Other
All Other net sales for the three-month period ended June 30, 2018 were $30.7 million, an increase of less than $0.1 million, compared to the three-month period ended June 30, 2017. This increase was primarily due to higher sales volumes,

partially offset by unfavorable price impact for the fine chemistry services business. All Other adjusted EBITDA was down 104%, or $2.5 million, for the three-month period ended June 30, 2018 in comparison to the corresponding period of 2017, primarily due to the unfavorable price impact and product mix for the fine chemistry services business.
Corporate
Corporate adjusted EBITDA was a charge of $27.4 million for the three-month period ended June 30, 2018, compared to a charge of $28.2 million for the corresponding period of 2017. The change was primarily due to lower SG&A spend more than offsetting $0.5 million of unfavorable currency translation.

Net Sales
For the six-month period ended June 30, 2018, we recorded net sales of $1.68 billion, an increase of $216.2 million, or 15%, compared to net sales of $1.46 billion for the six-month period ended June 30, 2017. Net sales increased due to $121.3 million of higher volumes primarily in our Lithium and Catalyst segments, $85.1 million of favorable pricing impacts across all three reportable segments and $35.4 million of favorable currency exchange impacting all three reportable segments, partially offset by the divestiture of the polyolefin catalyst and components portion of the PCS business of $25.7 million.

Gross Profit
For the six-month period ended June 30, 2018, our gross profit increased $89.4 million, or 17%, from the corresponding 2017 period. Included in Cost of goods sold for the six-month period ended June 30, 2018 is a decrease of $8.8 million in acquisition and integration related costs from various significant projects compared to the corresponding period in 2017. In addition, gross profit in 2017 included a $22.5 million charge related to the markup of inventory purchased as part of the Jiangli New Materials acquisition, restructuring costs of $2.9 million related to a plan to reduce costs at several locations and $9.8 million of gross profit related to the divested polyolefin catalyst and component portion of the PCS business. Excluding the impact of these items, gross profit increased by $65.0 million, or 12%, primarily due to $85.1 million in favorable price impacts and higher volumes more than offsetting higher costs related to Lithium royalty payments and material costs. Overall, these factors contributed to a gross profit margin for the six-month period ended June 30, 2018 of 36.8%, up from 36.1% in the corresponding period in 2017.
Selling, General and Administrative Expenses
For the six-month period ended June 30, 2018, our SG&A expenses decreased $0.5 million, or less than 1%, from the six-month period ended June 30, 2017. As a percentage of net sales, SG&A expenses were 13.4% for the six-month period ended June 30, 2018, compared to 15.5% for the corresponding period in 2017.
Research and Development Expenses
For the six-month period ended June 30, 2018, our R&D expenses decreased $4.6 million, or 11%, from the six-month period ended June 30, 2017. Included in R&D expenses for the six-month period ended June 30, 2017 were $5.8 million of restructuring costs related to our Lithium sites in Germany. As a percentage of net sales, R&D expenses were 2.2% and 2.9% for the six-month periods ended June 30, 2018 and 2017, respectively.
Gain on Sale of Business
The six-month period ended June 30, 2018 includes a gain before income taxes of $218.7 million related to the sale of the polyolefin catalysts and components portion of the PCS business, which closed in the second quarter of 2018.
Interest and Financing Expenses
Interest and financing expenses for the six-month period ended June 30, 2018 decreased $56.3 million to $26.8 million from the corresponding 2017 period, due mainly to a loss on early extinguishment of debt of $52.8 million in 2017. This was related to the tender premiums, fees, unamortized discounts and unamortized deferred financing costs from the repayment of the 3.00% Senior notes in full, €307.0 million of the 1.875% Senior notes and $174.7 million of the 4.50% Senior notes. The remaining difference is primarily related to the impact of higher capitalized interest from increased capital expenditures during 2018.
Other Expenses, Net
Other expenses, net, for the six-month period ended June 30, 2018 was $35.7 million compared to $1.4 million for the corresponding 2017 period. During the six-month period ended June 30, 2018, we recorded $28.0 million of legal accruals, related to products that Albemarle no longer manufactures and a previously disposed business and $15.6 million related to environmental charges related to a site formerly owned by Albemarle. During the six-month period ended June 30, 2017, we recorded $11.4 million of charges related to previously disposed properties or businesses, partially offset by a $7.4 million gain related to the acquisition of the remaining 50% interest of an equity investment in 2017. The remaining change was primarily due to a decrease in foreign exchange losses totaling $1.3 million and an increase in interest income.
Income Tax Expense
The effective income tax rate for the first six months of 2018 was 19.7% compared to 20.0% for the first six months of 2017. The difference between the U.S. federal statutory income tax rate of 21% and our effective income tax rate for the six-months ended June 30, 2018 was impacted by a variety of factors, primarily stemming from the location in which income is earned. The difference between the U.S. federal statutory income tax rate of 35% and our effective income tax rate for the six-months ended June 30, 2017 was primarily due to the impact of earnings from outside the U.S., and is mainly attributable to our share of the income of our JBC joint venture, a Free Zones company under the laws of the Hashemite Kingdom of Jordan. The decrease in the effective tax rate for the six-month period ended June 30, 2018 compared to the same period last year, was driven by a variety of factors, primarily stemming from a change in the geographic mix of earnings.
Equity in Net Income of Unconsolidated Investments
Equity in net income of unconsolidated investments was $39.6 million for the six-month period ended June 30, 2018 compared to $36.2 million in the same period last year. This increase of $3.4 million was primarily due higher equity income

reported by our Lithium joint venture, Windfield Holdings Pty. Ltd., partially offset by a decrease in equity income in our Catalyst segment.
Net Income Attributable to Noncontrolling Interests
For the six-month period ended June 30, 2018, net income attributable to noncontrolling interests was $15.4 million compared to $21.8 million in the same period last year. This decrease of $6.4 million was primarily due to a decrease in consolidated income related to our JBC joint venture from lower sales volumes related to the installation of additional production capacity in the current year.
Net Income Attributable to Albemarle Corporation
Net income attributable to Albemarle Corporation increased to $434.2 million in the six-month period ended June 30, 2018, from $154.5 million in the six-month period ended June 30, 2017. The increase is primarily due to the after-tax gain of $176.6 million related to the sale of the polyolefin catalysts and components portion of the PCS business, favorable pricing impacts in all reportable segments, favorable volumes in the Lithium and Catalyst segments and a $12.0 million decrease in acquisition and integration costs in the six-month period ended June 30, 2018, as well as a $52.8 million loss on early extinguishment of debt related to the repayment of senior notes and $17.1 million of restructuring and other costs recorded in the corresponding period of 2017. This was partially offset by $28.0 million of legal accruals, related to products that Albemarle no longer manufactures and a previously disposed business, $15.6 million related to environmental charges related to a site formerly owned by Albemarle recorded in the six-month period ended June 30, 2018, a $15.0 million charitable contribution to the Albemarle Foundation and a $7.4 million gain related to the acquisition of the remaining 50% interest of equity investment in the corresponding period of 2017.
Other Comprehensive (Loss) Income, Net of Tax
Total other comprehensive (loss) income, net of tax, was ($76.1) million for the six-month period ended June 30, 2018 compared to $116.3 million for the corresponding period in 2017. The majority of these amounts are the result of translating our foreign subsidiary financial statements from their local currencies to U.S. Dollars. In the six-month period ended June 30, 2018, other comprehensive loss from foreign currency translation adjustments was $86.0 million, primarily as a result of unfavorable movements in the Euro of approximately $63 million, the Brazilian Real of approximately $12 million, the Chinese Renminbi of approximately $4 million and a net unfavorable variance in various other currencies totaling approximately $7 million. Also included in total other comprehensive loss for the 2018 period is income of $8.6 million in connection with the revaluation of our Euro-based 1.875% Senior notes which have been designated as a hedge of our net investment in foreign operations. In the corresponding 2017 period, other comprehensive income from foreign currency translation adjustments was $143.1 million, primarily resulting from favorable movements in the Euro of approximately $124 million, the Korean Won of approximately $8 million, the Chinese Renminbi of approximately $5 million and a net favorable variance in various other currencies totaling approximately $6 million (each approximately $3 million or less). Also included in total other comprehensive income for the corresponding 2017 period is a loss of $27.9 million in connection with the revaluation of our Euro-based 1.875% Senior notes which have been designated as a hedge of our net investment in foreign operations.

(a) | See “Gain on Sale of Business” on page 36 for a description of this gain.

(b) | Included amounts for the six-month periods ended June 30, 2018 and 2017 recorded in (1) Cost of goods sold of $1.9 million and $10.7 million, respectively; and (2) Selling, general and administrative expenses of $6.8 million and $10.1 million, respectively, relating to various significant projects.

(c) | Included in Other expenses, net is a $17.6 million accrual resulting from a jury rendered verdict against Albemarle related to certain business concluded under a 2014 sales agreement for products that Albemarle no longer manufactures and a $10.4 million accrual resulting from a proposed settlement in a legal matter related to guarantees from a previously disposed business.

(d) | Included in Selling, general and administrative expenses is a charitable contribution, using a portion of the proceeds received from the sale of the polyolefin catalysts and components portion of the PCS business, to the Albemarle Foundation, a non-profit organization that sponsors grants, health and social projects, educational initiatives, disaster relief, matching gift programs, scholarships and other charitable initiatives in locations where our employees live and operate. This contribution is in addition to the normal annual contribution made to the Albemarle Foundation by the Company, and is significant in size and nature in that it is intended to provide more long-term benefits in the communities where we live and operate.

(e) | Included amounts for the six months ended June 30, 2018 recorded in:

• | Cost of goods sold - $1.1 million for the write-off of fixed assets related to a major capacity expansion in our Jordanian joint venture.

• | Selling, general and administrative expenses - $1.4 million gain related to a refund from Chilean authorities due to an overpayment made in a prior year.

• | Other expenses, net - $15.6 million of environmental charges related to a site formerly owned by Albemarle and $1.0 million related to the revision of previously recorded expenses of disposed businesses.

(f) | In connection with the acquisition of Jiangli New Materials, the Company valued inventory purchased from Jiangli New Materials at fair value, which resulted in a markup of the underlying net book value of the inventory totaling approximately $23.1 million. The inventory markup was expensed over the estimated remaining selling period. For the six-month period ended June 30, 2017, $22.5 million was included in Cost of goods sold related to the utilization of the inventory markup.

(g) | During 2017, we initiated action to reduce costs in each of our reportable segments at several locations, primarily at our Lithium sites in Germany. Based on the restructuring plans, we have recorded expenses of $2.9 million in Cost of goods sold, $8.4 million in Selling, general and administrative expenses and $5.8 million in Research and development expenses, primarily related to restructuring costs. The unpaid balance is recorded in Accrued expenses at June 30, 2018, with the expectation that the majority of this plan will be completed by the end of 2018.

(h) | Gain recorded in Other expenses, net related to the acquisition of the remaining 50% interest in the Sales de Magnesio Ltda. joint venture in Chile.

(i) | During the first quarter of 2017, we repaid the 3.00% Senior notes in full, €307.0 million of the 1.875% Senior notes and $174.7 million of the 4.50% Senior notes, as well as related tender premiums of $45.2 million. As a result, included in Interest and financing expenses is a loss on early extinguishment of debt of $52.8 million, representing the tender premiums, fees unamortized discounts and unamortized deferred financing costs from the redemption of these senior notes.

(j) | Included in Selling, general and administrative expenses is $2.0 million for additional capital reserve contributions to a multiemployer plan, which is subject to a financial improvement plan. In addition, additional capital reserve contributions for this multiemployer plan of $2.9 million, included in Other expenses, net, have been made to indemnify previously divested businesses.

Lithium
Lithium segment net sales for the six-month period ended June 30, 2018 were $615.6 million, up $155.5 million, or 34%, compared to the corresponding period of 2017. The increase was primarily driven by $78.4 million of higher volume, $58.6 million of favorable pricing due to strong demand, which continues to drive investment in new capacity, and $18.6 million of favorable currency translation primarily driven by the weaker U.S. Dollar against the Euro. Adjusted EBITDA for Lithium was up 27%, or $57.6 million, to $272.6 million for the six-month period ended June 30, 2018, compared to the corresponding period of 2017, primarily due to favorable pricing, higher sales volumes and $2.2 million of favorable currency translation, partially offset by higher royalty payments.
Bromine Specialties
Bromine Specialties segment net sales for the six-month period ended June 30, 2018 were $446.2 million, up $23.0 million, or 5%, compared to the corresponding period of 2017. The increase was driven mainly by $17.0 million in favorable price in flame retardants, bromine and other derivatives due to continued strong demand and $7.4 million of favorable currency translation driven by the weaker U.S. Dollar against the Euro. This was partially offset by lower volumes related to constraints in elemental bromine during the first quarter of 2018. Adjusted EBITDA for Bromine Specialties was up 7%, or $8.8 million, to $139.3 million for the six-month period ended June 30, 2018, compared to the corresponding period of 2017. This increase was primarily due to favorable pricing across most products and $6.5 million of favorable currency translation related to the Euro, more than offsetting the impact of lower volumes and higher freight and material costs.
Catalysts
Catalysts segment net sales for the six-month period ended June 30, 2018 were $545.7 million, an increase of $33.9 million, or 7%, compared to the corresponding period of 2017. This increase was primarily due to $38.5 million of higher volumes primarily related to FCC and PCS, $11.6 million of favorable price impacts due to pass through of higher metals costs and $9.4 million of favorable currency translation primarily driven by the weaker U.S. Dollar against the Euro. Partially offsetting this was $25.7 million related to the divestiture of polyolefin catalyst and components portion of the PCS business. Catalysts adjusted EBITDA increased 4%, or $5.8 million, to $142.9 million for the six-month period ended June 30, 2018 in comparison to the corresponding period of 2017. This increase was primarily due to favorable price impact and higher volumes, partially offset by higher metals material costs and $9.8 million earnings in the prior year related to the divested polyolefin catalyst and components business.
All Other
All Other net sales for the six-month period ended June 30, 2018 were $67.9 million, an increase of $4.8 million, or 8%, compared to the six-month period ended June 30, 2017. This increase was primarily due to higher sales volumes, more than offsetting unfavorable pricing for the fine chemistry services business. All Other adjusted EBITDA was down 51%, or $3.8 million, for the six-month period ended June 30, 2018 in comparison to the corresponding period of 2017, primarily due to unfavorable price impact and product mix for the fine chemistry services business.

Corporate
Corporate adjusted EBITDA was a charge of $51.4 million for the six-month period ended June 30, 2018, compared to a charge of $60.1 million for the corresponding period of 2017. The change was primarily due to lower SG&A spend related to compensation and professional fees and $1.2 million of favorable currency translation.
Financial Condition and Liquidity
Overview
The principal uses of cash in our business generally have been capital investments and resource development costs, funding working capital and service of debt. We also make contributions to our defined benefit pension plans, pay dividends to our shareholders and repurchase shares of our common stock. Historically, cash to fund the needs of our business has been principally provided by cash from operations, debt financing and equity issuances.
We are continually focused on working capital efficiency particularly in the areas of accounts receivable and inventory. We anticipate that cash on hand, cash provided by operating activities, proceeds from divestitures and borrowings will be sufficient to pay our operating expenses, satisfy debt service obligations, fund capital expenditures and other investing activities, fund pension contributions and pay dividends for the foreseeable future.
Cash Flow
During the first six months of 2018, cash on hand, cash provided by operations and $416.7 million of net proceeds from divestitures funded $213.3 million of commercial paper repayments, net of borrowings, a $250.0 million accelerated share repurchase program, $280.9 million of capital expenditures for plant, machinery and equipment, and dividends to shareholders of $72.5 million. Our operations provided $223.9 million of cash flows during the first six months of 2018, as compared to an outflow of $54.5 million for the first six months of 2017, with the increase arising from the payment of approximately $255 million in taxes related to the Chemetall divestiture in 2017. Our cash from operations in 2018 included an outflow from working capital changes of $91.2 million, primarily due to the build up of inventory in the Lithium and Catalysts reportable segments, as well as an increase in accounts receivable from the Lithium segment as a result of increased sales in 2018. Overall, our cash and cash equivalents decreased by approximately $229.2 million to $908.1 million at June 30, 2018, down from $1.14 billion at December 31, 2017.
Under our existing Board authorized share repurchase program, the Company entered into an ASR agreement with a financial institution on May 11, 2018. Under the ASR agreement, in the second quarter of 2018, the Company paid $250 million from available cash on hand and received and retired 2,354,133 shares of our common stock with a fair market value of $230 million, which reduced the Company’s weighted average shares outstanding for purposes of calculating basic and diluted earnings per share for the three-month and six-month periods ended June 30, 2018. The total number of shares to ultimately be delivered under the ASR agreement will be determined upon completion of the ASR agreement, which will be by the end of the third quarter of 2018, and will generally be based on the daily Rule 10b-18 volume-weighted average prices of the Company’s common stock over the term of the ASR agreement, less an agreed discount. As of June 30, 2018, there were 10,304,784 remaining shares available for repurchase under the Company’s authorized share repurchase program.
Capital expenditures for the six-month period ended June 30, 2018 of $280.9 million were associated with property, plant and equipment additions. We expect our capital expenditures to approximate $800 to $900 million in 2018 for Lithium growth and capacity increases, productivity and continuity of operations projects. Of the total capital expenditures, our projects related to the continuity of operations is expected to remain in the range of 4-6% of net sales, similar to prior years.
On April 3, 2018, the Company closed the sale of the polyolefin catalysts and components portion of its PCS business to W.R. Grace & Co. for proceeds of approximately $416.7 million in cash and recorded a gain of $218.7 million before income taxes in the second quarter of 2018 related to the sale of this business. The transaction includes Albemarle’s Product Development Center located in Baton Rouge, Louisiana, and operations at its Yeosu, South Korea site. The sale does not include the Company’s organometallics or curatives portion of its PCS business. The sale of the polyolefin catalysts business and components reflects the Company’s commitment to investing in the future growth of its high priority businesses and returning capital to shareholders.
Net current assets were $1.24 billion and $1.28 billion at June 30, 2018 and December 31, 2017, respectively. Changes in the components of net current assets are due to the timing of the sale of goods and other ordinary transactions leading up to the balance sheet dates and are not the result of any policy changes by the Company, and do not reflect any change in either the quality of our net current assets or our expectation of success in converting net working capital to cash in the ordinary course of business.

On February 23, 2018, we increased our quarterly dividend rate to $0.335 per share, a 5% increase from the quarterly rate of $0.32 per share paid in 2017.
At June 30, 2018 and December 31, 2017, our cash and cash equivalents included $593.2 million and $1.10 billion, respectively, held by our foreign subsidiaries. The majority of these foreign cash balances are associated with earnings that we have asserted are indefinitely reinvested and which we plan to use to support our continued growth plans outside the U.S. through funding of capital expenditures, acquisitions, research, operating expenses or other similar cash needs of our foreign operations. From time to time, we repatriate cash associated with earnings from our foreign subsidiaries to the U.S. for normal operating needs through intercompany dividends, but only from subsidiaries whose earnings we have not asserted to be indefinitely reinvested or whose earnings qualify as “previously taxed income” as defined by the Internal Revenue Code. During the first six months of 2018 and 2017, we repatriated approximately $611.3 million and $5.3 million of cash, respectively, as part of these foreign earnings cash repatriation activities. A portion of the cash repatriations was used to repay a net amount of $213.3 million of commercial paper during 2018. We continue to evaluate our indefinite reinvestment assertion as a result of the TCJA.
While we continue to closely monitor our cash generation, working capital management and capital spending in light of continuing uncertainties in the global economy, we believe that we will continue to have the financial flexibility and capability to opportunistically fund future growth initiatives. Additionally, we anticipate that future capital spending, including business acquisitions, share repurchases and other cash outlays, should be financed primarily with cash flow provided by operations and cash on hand, with additional cash needed, if any, provided by borrowings. The amount and timing of any additional borrowings will depend on our specific cash requirements.
Long-Term Debt
We currently have the following senior notes outstanding:

Issue Month/Year |  | Principal (in millions) |  | Interest Rate |  | Interest Payment Dates |  | Maturity Date
December 2014 |  | €393.0 |  | 1.875% |  | December 8 |  | December 8, 2021
November 2014 |  | $425.0 |  | 4.15% |  | June 1 | December 1 |  | December 1, 2024
November 2014 |  | $350.0 |  | 5.45% |  | June 1 | December 1 |  | December 1, 2044
December 2010 |  | $175.3 |  | 4.50% |  | June 15 | December 15 |  | December 15, 2020

Our senior notes are senior unsecured obligations and rank equally with all our other senior unsecured indebtedness from time to time outstanding. The senior notes are effectively subordinated to any of our existing or future secured indebtedness and to the existing and future indebtedness of our subsidiaries. As is customary for such long-term debt instruments, each senior note outstanding has terms that allow us to redeem the notes before its maturity, in whole at any time or in part from time to time, at a redemption price equal to the greater of (i) 100% of the principal amount of the senior notes to be redeemed, or (ii) the sum of the present values of the remaining scheduled payments of principal and interest thereon (exclusive of interest accrued to the date of redemption) discounted to the redemption date on a semi-annual basis using the comparable government rate (as defined in the indentures governing the senior notes) plus between 25 and 40 basis points, depending on the note, plus, in each case, accrued interest thereon to the date of redemption. Holders may require us to purchase such notes at 101% upon a change of control triggering event, as defined in the indentures. The senior notes are subject to typical events of default, including bankruptcy and insolvency events, nonpayment and the acceleration of certain subsidiary indebtedness of $40 million or more caused by a nonpayment default.
On June 21, 2018, we entered into a revolving, unsecured credit agreement (“2018 Credit Agreement”) to replace our revolving, unsecured credit agreement dated as of February 7, 2014, as amended. The 2018 Credit Agreement currently provides for borrowings of up to $1.0 billion and matures on June 21, 2023. Borrowings under the 2018 Credit Agreement bear interest at variable rates based on an average London inter-bank offered rate (“LIBOR”) for deposits in the relevant currency plus an applicable margin which ranges from 0.910% to 1.500%, depending on the Company’s credit rating from Standard & Poor’s Ratings Services, Moody’s Investors Services and Fitch Ratings. The applicable margin on the facility was 1.125% as of June 30, 2018. There were no borrowings outstanding under the 2018 Credit Agreement as of June 30, 2018.
Borrowings under the 2018 Credit Agreement are conditioned upon satisfaction of certain conditions precedent, including the absence of defaults. The Company is subject to one financial covenant, as well as customary affirmative and negative covenants. The financial covenant requires that the Company’s consolidated funded debt to consolidated EBITDA ratio (as such terms are defined in the 2018 Credit Agreement) to be less than or equal to 3.50:1.00, subject to adjustments in accordance with the terms of the 2018 Credit Agreement relating to a consummation of an acquisition where the consideration includes cash proceeds from issuance of funded debt in excess of $500 million. The 2018 Credit Agreement also contains customary
42

Table of Contents
default provisions, including defaults for non-payment, breach of representations and warranties, insolvency, non-performance of covenants and cross-defaults to other material indebtedness. The occurrence of an event of default under the 2018 Credit Agreement could result in all loans and other obligations becoming immediately due and payable and the credit facility being terminated.
On May 29, 2013, we entered into agreements to initiate a commercial paper program on a private placement basis under which we may issue unsecured commercial paper notes (the “Commercial Paper Notes”) from time-to-time up to a maximum aggregate principal amount outstanding at any time of $750.0 million. The proceeds from the issuance of the Commercial Paper Notes are expected to be used for general corporate purposes, including the repayment of other debt of the Company. Our 2018 Credit Agreement is available to repay the Commercial Paper Notes, if necessary. Aggregate borrowings outstanding under the 2018 Credit Agreement and the Commercial Paper Notes will not exceed the $1.0 billion current maximum amount available under the 2018 Credit Agreement. The Commercial Paper Notes will be sold at a discount from par, or alternatively, will be sold at par and bear interest at rates that will vary based upon market conditions at the time of issuance. The maturities of the Commercial Paper Notes will vary but may not exceed 397 days from the date of issue. The definitive documents relating to the commercial paper program contain customary representations, warranties, default and indemnification provisions. At June 30, 2018, we had $208.0 million of Commercial Paper Notes outstanding bearing a weighted-average interest rate of approximately 2.44% and a weighted-average maturity of 37 days. During the first six months of 2018, we repaid a net amount of $213.3 million of commercial paper notes using cash on hand. The Commercial Paper Notes are classified as Current portion of long-term debt in our condensed consolidated balance sheets at June 30, 2018 and December 31, 2017.
The non-current portion of our long-term debt amounted to $1.41 billion at June 30, 2018, compared to $1.42 billion at December 31, 2017. In addition, at June 30, 2018, we had the ability to borrow $792.0 million under our commercial paper program and the 2018 Credit Agreement, and $248.3 million under other existing lines of credit, subject to various financial covenants under our 2018 Credit Agreement. We have the ability and intent to refinance our borrowings under our other existing credit lines with borrowings under the 2018 Credit Agreement, as applicable. Therefore, the amounts outstanding under those credit lines, if any, are classified as long-term debt. We believe that as of June 30, 2018, we were, and currently are, in compliance with all of our long term debt covenants.
Off-Balance Sheet Arrangements
In the ordinary course of business with customers, vendors and others, we have entered into off-balance sheet arrangements, including bank guarantees and letters of credit, which totaled approximately $61.8 million at June 30, 2018. None of these off-balance sheet arrangements has, or is likely to have, a material effect on our current or future financial condition, results of operations, liquidity or capital resources.
Other Obligations
There have been no significant changes in our contractual obligations from the information we provided in our Annual Report on Form 10-K for the year ended December 31, 2017.
Total expected 2018 contributions to our domestic and foreign qualified and nonqualified pension plans, including our SERP, should approximate $13 million. We may choose to make additional pension contributions in excess of this amount. We have made contributions of $5.9 million to our domestic and foreign pension plans (both qualified and nonqualified) during the six-month period ended June 30, 2018.
The liability related to uncertain tax positions, including interest and penalties, recorded in Other noncurrent liabilities totaled $22.3 million at June 30, 2018 and $24.4 million at December 31, 2017. Related assets for corresponding offsetting benefits recorded in Other assets totaled $12.2 million at June 30, 2018 and $14.6 million at December 31, 2017. We cannot estimate the amounts of any cash payments associated with these liabilities for the remainder of 2018 or the next twelve months, and we are unable to estimate the timing of any such cash payments in the future at this time.
We are subject to federal, state, local and foreign requirements regulating the handling, manufacture and use of materials (some of which may be classified as hazardous or toxic by one or more regulatory agencies), the discharge of materials into the environment and the protection of the environment. To our knowledge, we are currently in compliance, and expect to continue to comply, in all material respects with applicable environmental laws, regulations, statutes and ordinances. Compliance with existing federal, state, local and foreign environmental protection laws is not expected to have a material effect on capital expenditures, earnings or our competitive position, but the costs associated with increased legal or regulatory requirements could have an adverse effect on our results.
Among other environmental requirements, we are subject to the federal Superfund law, and similar state laws, under which we may be designated as a potentially responsible party (“PRP”) and may be liable for a share of the costs associated with cleaning up various hazardous waste sites. Management believes that in cases in which we may have liability as a PRP,
43

Table of Contents
our liability for our share of cleanup is de minimis. Further, almost all such sites represent environmental issues that are quite mature and have been investigated, studied and in many cases settled. In de minimis situations, our policy generally is to negotiate a consent decree and to pay any apportioned settlement, enabling us to be effectively relieved of any further liability as a PRP, except for remote contingencies. In other than de minimis PRP matters, our records indicate that unresolved PRP exposures should be immaterial. We accrue and expense our proportionate share of PRP costs. Because management has been actively involved in evaluating environmental matters, we are able to conclude that the outstanding environmental liabilities for unresolved PRP sites should not have a material adverse effect upon our results of operations or financial condition.
Liquidity Outlook
We anticipate that cash on hand and cash provided by operating activities, divestitures, including the proceeds received from the sale of the polyolefin catalysts and components business, and borrowings will be sufficient to pay our operating expenses, satisfy debt service obligations, fund any capital expenditures and share repurchases, make acquisitions, make pension contributions and pay dividends for the foreseeable future. Our main focus over the next three years, in terms of uses of cash, will be investing in growth of the businesses and the return of value to shareholders. Additionally, we will continue to evaluate the merits of any opportunities that may arise for acquisitions of businesses or assets, which may require additional liquidity.
Our cash flows from operations may be negatively affected by adverse consequences to our customers and the markets in which we compete as a result of moderating global economic conditions and reduced capital availability.
While we maintain business relationships with a diverse group of financial institutions, an adverse change in their credit standing could lead them to not honor their contractual credit commitments, decline funding under existing but uncommitted lines of credit, not renew their extensions of credit or not provide new financing. While the global corporate bond and bank loan markets remain strong, periods of elevated uncertainty related to global economic and/or geopolitical concerns may limit efficient access to such markets for extended periods of time. If such concerns heighten, we may incur increased borrowing costs and reduced credit capacity as our various credit facilities mature. When the U.S. Federal Reserve or similar national reserve banks in other countries decide to tighten the monetary supply in response, for example, to improving economic conditions, we may incur increased borrowing costs as interest rates increase on our variable rate credit facilities, as our various credit facilities mature or as we refinance any maturing fixed rate debt obligations, although these cost increases would be partially offset by increased income rates on portions of our cash deposits.
Overall, with generally strong cash-generative businesses and no significant long-term debt maturities before 2020, we believe we have, and will maintain, a solid liquidity position.
Following receipt of information regarding potential improper payments being made by third party sales representatives of our Refining Solutions business, within our Catalysts segment, we promptly retained outside counsel and forensic accountants to investigate potential violations of the Company’s Code of Conduct, the Foreign Corrupt Practices Act and other potentially applicable laws. Based on this internal investigation, we have voluntarily self-reported potential issues relating to the use of third party sales representatives in our Refining Solutions business, within our Catalysts segment, to the U.S. Department of Justice (“DOJ”) and SEC, and are cooperating with the DOJ and SEC in their review of these matters. In connection with our internal investigation, we have implemented, and are continuing to implement, appropriate remedial measures.
At this time, we are unable to predict the duration, scope, result or related costs associated with any investigations by the DOJ or SEC. We also are unable to predict what, if any, action may be taken by the DOJ or SEC or what penalties or remedial actions they may seek. Any determination that our operations or activities are not in compliance with existing laws or regulations, however, could result in the imposition of fines, penalties, disgorgement, equitable relief or other losses. We do not believe, however, that any fines, penalties, disgorgement, equitable relief or other losses would have a material adverse effect on our financial condition or liquidity.
We had cash and cash equivalents totaling $908.1 million at June 30, 2018, of which $593.2 million is held by our foreign subsidiaries. This cash represents an important source of our liquidity and is invested in bank accounts or money market investments with no limitations on access. The cash held by our foreign subsidiaries is intended for use outside of the U.S. We anticipate that any needs for liquidity within the U.S. in excess of our cash held in the U.S. can be readily satisfied with borrowings under our existing U.S. credit facilities or our commercial paper program.

additional details. There have been no other significant changes in our critical accounting policies and estimates from the information we provided in our Annual Report on Form 10-K for the year ended December 31, 2017.
Recent Accounting Pronouncements
For a description of recent accounting pronouncements, see Item 1 Financial Statements – Note 18, “Recently Issued Accounting Pronouncements.”

Item 3. | Quantitative and Qualitative Disclosures About Market Risk.

There have been no significant changes in our interest rate risk, foreign currency exchange rate exposure, marketable securities price risk or raw material price risk from the information we provided in our Annual Report on Form 10-K for the year ended December 31, 2017.
We had variable interest rate borrowings of $215.3 million outstanding at June 30, 2018, bearing a weighted average interest rate of 2.37% and representing approximately 13% of our total outstanding debt. A hypothetical 10% change (approximately 24 basis points) in the interest rate applicable to these borrowings would change our annualized interest expense by approximately $0.5 million as of June 30, 2018. We may enter into interest rate swaps, collars or similar instruments with the objective of reducing interest rate volatility relating to our borrowing costs.
Our financial instruments which are subject to foreign currency exchange risk consist of foreign currency forward contracts with an aggregate notional value of $493.1 million and with a fair value representing a net asset position of $0.2 million at June 30, 2018. Fluctuations in the value of these contracts are generally offset by the value of the underlying exposures being hedged. We conducted a sensitivity analysis on the fair value of our foreign currency hedge portfolio assuming an instantaneous 10% change in select foreign currency exchange rates from their levels as of June 30, 2018, with all other variables held constant. A 10% appreciation of the U.S. Dollar against foreign currencies that we hedge would result in a decrease of approximately $6.1 million in the fair value of our foreign currency forward contracts. A 10% depreciation of the U.S. Dollar against these foreign currencies would result in an increase of approximately $3.4 million in the fair value of our foreign currency forward contracts. The sensitivity of the fair value of our foreign currency hedge portfolio represents changes in fair values estimated based on market conditions as of June 30, 2018, without reflecting the effects of underlying anticipated transactions. When those anticipated transactions are realized, actual effects of changing foreign currency exchange rates could have a material impact on our earnings and cash flows in future periods.

Item 4. | Controls and Procedures.

Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, we conducted an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended, or the Exchange Act), as of the end of the period covered by this report. Based on this evaluation, our principal executive officer and principal financial officer concluded that, as of the end of the period covered by this report, our disclosure controls and procedures are effective to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act, is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure.
No change in our internal control over financial reporting (as such term is defined in Exchange Act Rule 13a-15(f)) occurred during the second quarter ended June 30, 2018 that materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
PART II. OTHER INFORMATION

Item 1. | Legal Proceedings.

We are involved from time to time in legal proceedings of types regarded as common in our business, including administrative or judicial proceedings seeking remediation under environmental laws, such as Superfund, products liability, breach of contract liability and premises liability litigation. Where appropriate, we may establish financial reserves for such proceedings. We also maintain insurance to mitigate certain of such risks. Additional information with respect to this Item 1 is contained in Note 10 to the Notes to the Condensed Consolidated Financial Statements in this Quarterly Report on Form 10-Q.

Item 1A. | Risk Factors.

While we attempt to identify, manage and mitigate risks and uncertainties associated with our business to the extent practical under the circumstances, some level of risk and uncertainty will always be present. The risk factors set forth in Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2017 describes some of the risks and uncertainties associated with our business. These risks and uncertainties have the potential to materially affect our results of operations and our financial condition. We do not believe that there have been any material changes to the risk factors previously disclosed in our Annual Report on Form 10-K for the year ended December 31, 2017.

Item 2. | Unregistered Sales of Equity Securities and Use of Proceeds.

The following table summarizes our repurchases of equity securities for the three-month period ended June 30, 2018:

April 1, 2018 to April 30, 2018 |  | — |  |  | $ | — |  |  | — |  |  | 12,658,917 |
May 1, 2018 to May 31, 2018(b) |  | 2,029,632 |  |  | 98.54 |  |  | 2,029,632 |  |  | 10,629,285 |

Total |  | 2,354,133 |  |  |  |  | 2,354,133 |  |  |

(a) | Our stock repurchase plan, which was authorized by our Board of Directors, permits the Company to repurchase up to a maximum of fifteen million shares. The Company has regularly repurchased shares under the stock repurchase plan, resulting in the Board of Directors periodically authorizing additional shares for repurchase under the plan. The stock repurchase plan will expire when we have repurchased all shares authorized for repurchase thereunder, unless the stock repurchase plan is earlier terminated by action of our Board of Directors or further shares are authorized for repurchase.

(b) | In the second quarter of 2018, we paid $250 million under the ASR agreement, receiving and retiring 2,354,133 shares. This agreement is expected to be completed in the third quarter of 2018. The Average Price Paid Per Share was calculated using the closing price per share of our common stock the date the ASR Agreement was signed for the initial delivery, and the daily Rule 10b-18 volume-weighted average prices of our common stock over the term of the ASR agreement, less an agreed discount for the remaining shares repurchased. See Item 1 Financial Statements - Note 6, “Earnings Per Share,” to the condensed consolidated financial statements included in this quarterly report.
