Rockwood Acquisition Financing

The net proceeds from senior notes we issued in the fourth quarter of 2014, together with borrowings under our revolving credit agreement, commercial paper notes, August 15, 2014 term loan credit agreement and a senior unsecured cash bridge facility, were used to finance the cash portion of the consideration for the acquisition of Rockwood, pay fees and expenses related to the acquisition, repay our 5.10% senior notes, with the remainder, if any, used for general corporate purposes.

Senior Notes

In the fourth quarter of 2014, we issued a series of senior notes (collectively, the “2014 Senior Notes”) as follows:


•	€700.0 million aggregate principal amount of senior notes, issued on December 8, 2014, bearing interest at a rate of 1.875% payable annually on December 8 of each year, beginning in 2015. The effective interest rate on these senior notes is approximately 2.10%. These senior notes mature on December 8, 2021.


•	$250.0 million aggregate principal amount of senior notes, issued on November 24, 2014, bearing interest at a rate of 3.00% payable semi-annually on June 1 and December 1 of each year, beginning June 1, 2015. The effective interest rate on these senior notes is approximately 3.18%. These senior notes mature on December 1, 2019.


•	$425.0 million aggregate principal amount of senior notes, issued on November 24, 2014, bearing interest at a rate of 4.15% payable semi-annually on June 1 and December 1 of each year, beginning June 1, 2015. The effective interest rate on these senior notes is approximately 5.06%. These senior notes mature on December 1, 2024.


•	$350.0 million aggregate principal amount of senior notes, issued on November 24, 2014, bearing interest at a rate of 5.45% payable semi-annually on June 1 and December 1 of each year, beginning June 1, 2015. The effective interest rate on these senior notes is approximately 5.50%. These senior notes mature on December 1, 2044.

Upon completion of the Rockwood acquisition, we assumed Rockwood’s senior notes with an aggregate principal amount of $1.25 billion. These senior notes bore interest at a rate of 4.625% payable semi-annually on April 15 and October 15 of each year, and had a scheduled maturity of October 15, 2020. At October 15, 2015, the carrying amount of the 4.625% senior notes included an unamortized premium of approximately $38.0 million, which resulted from an adjustment to fair value upon our assumption of the notes from Rockwood. The effective interest rate of the notes was approximately 3.95%.

Under the terms of the indenture governing the 4.625% senior notes, as amended and supplemented, on October 15, 2015, our wholly-owned subsidiary, Rockwood Specialties Group, Inc., redeemed all of the outstanding 4.625% senior notes at a redemption price equal to 103.469% of the principal amount of the notes, representing a premium of $43.3 million, plus accrued and unpaid interest to the redemption date. The guarantees of the 4.625% senior notes and the 2014 Senior Notes were released upon repayment of the 4.625% senior notes. Included in Interest and financing expenses in our consolidated statements of income and Other, net, in our consolidated statements of cash flows for the year ended December 31, 2015 is a loss on early extinguishment of approximately $5.4 million related to these senior notes.

Our $350.0 million aggregate principal amount of senior notes, issued on December 10, 2010, bear interest at a rate of 4.50% payable semi-annually on June 15 and December 15 of each year. The effective interest rate on these senior notes is approximately 4.70%. These senior notes mature on December 15, 2020.

Our $325.0 million aggregate principal amount of senior notes, which were issued on January 20, 2005 and bore interest at a rate of 5.10%, matured and were repaid on February 1, 2015. The effective interest rate on these senior notes was approximately 5.19%. As a result of the refinancing of these senior notes prior to December 31, 2014, these senior notes were included in Current portion of long-term debt at December 31, 2014.

In anticipation of refinancing our 5.10% senior notes in the fourth quarter of 2014, on January 22, 2014, we entered into a pay fixed, receive variable rate forward starting interest rate swap with J.P. Morgan Chase Bank, N.A., to be effective October 15, 2014. Our risk management objective and strategy for undertaking this hedge was to eliminate the variability in the interest rate and partial credit spread on the 20 future semi-annual coupon payments that we will pay in connection with our 4.15% senior notes. The notional amount of the swap was $325.0 million and the fixed rate was 3.281%, with the cash settlement determined by reference to the changes in the U.S. Dollar 3-month LIBOR and credit spreads from the date we entered into the swap until the date the swap was settled (October 15, 2014). This derivative financial instrument was designated and accounted for as a cash flow hedge under ASC 815, Derivatives and Hedging. We determined there was no ineffectiveness during the term of the swap. On October 15, 2014, the swap was settled, resulting in a payment to the counterparty of $33.4 million. This amount was recorded in Accumulated other comprehensive (loss) income and is being amortized to interest expense over the life of the 4.15% senior notes. The amount to be reclassified to interest expense from Accumulated other comprehensive (loss) income during the next twelve months is approximately $3.3 million.

In connection with the offering of the 1.875% Euro-denominated senior notes which were priced on December 1, 2014, we entered into two forward contracts on November 24, 2014, each with a notional value of €350.0 million, to exchange a total of €700.0 million for U.S. Dollars, with settlement occurring on December 18, 2014, and with the total notional value representing an amount equivalent to the gross proceeds from the offering of the 1.875% Euro-denominated senior notes. The objective of entering into these forward contracts was to minimize the financial impact of changes in the Euro-to-U.S. Dollar exchange rate with respect to our foreign subsidiaries where the Euro serves as the functional currency. From the effective date of the contracts until the date of settlement, the forward contracts were designated as effective hedges of our net investment in these foreign subsidiaries. Upon settlement, a gain of $5.2 million was recorded in accumulated other comprehensive (loss) income, and such amount is expected to remain in accumulated other comprehensive (loss) income until the complete or substantially complete liquidation of our investment in these foreign subsidiaries. On December 18, 2014, the carrying value of the 1.875% Euro-denominated senior notes was designated as an effective hedge of our net investment in foreign subsidiaries where the Euro serves as the functional currency, and beginning on the date of designation, gains or losses on the revaluation of these senior notes to our reporting currency have been and will be recorded in accumulated other comprehensive (loss) income. During the years ended December 31, 2015 and 2014, gains of $50.9 million and $12.8 million were recorded in accumulated other comprehensive (loss) income in connection with the revaluation of these senior notes to our reporting currency.

September 2015 Term Loan Agreement

The 4.625% senior notes we assumed from Rockwood were repaid with proceeds from a new term loan agreement we entered into on September 14, 2015 (the “September 2015 Term Loan Agreement”) with JPMorgan Chase Bank, N.A. (the “Administrative Agent”) and certain other lenders. The September 2015 Term Loan Agreement provides for borrowings under a 364-day term loan facility (the “364-Day Facility”) and a five-year term loan facility (the “Five-Year Facility”), or collectively, the “Term loan facilities.” As of December 31, 2015, aggregate amounts outstanding under the 364-Day Facility and the Five-Year Facility were $300.0 million and $950.0 million, respectively. As of February 19, 2016, we repaid the 364-Day Facility in full and we repaid approximately $31 million of borrowings under the Five-Year Facility, each primarily with proceeds from the sale of the Company’s Tribotecc metal sulfides business and the sale of the Company’s minerals-based flame retardants and specialty chemicals businesses, both of which closed in the first quarter of 2016. Borrowings under the facilities bear interest equal to, at the option of the Company: (a) LIBOR plus a margin ranging from 1.000% to 1.875% per annum depending upon the long-term, unsecured, senior, non-credit enhanced debt rating of the Company, or (b) a base rate (defined as the highest of (i) the Federal Funds Rate plus 0.50%; (ii) the rate of interest in effect for such day as publicly announced from time to time by the Administrative Agent as its “prime rate”; or (iii) one-month LIBOR plus 1.00%) plus a margin of 0.000% to 0.875% per annum depending upon the long-term, unsecured, senior, non-credit enhanced debt rating of the Company. As of December 31, 2015, the interest rate on both Term loan facilities was LIBOR plus 1.375%.

Borrowings under the 364-Day Facility were required to be repaid 364 days after initial funding. Borrowings under the Five-Year Facility are required to be repaid in equal quarterly installments on the last business day of each of March, June, September and December, beginning with September 30, 2016, and ending with the last such day to occur prior to the fifth anniversary after initial funding (each a “Payment Date”), in an aggregate principal amount equal to (a) in the case of each Payment Date occurring on or after the first anniversary and prior to the second anniversary of initial funding, 1.25% of the aggregate principal amount of such loans, and (b) in the case of each Payment Date occurring on or after the second anniversary of initial funding, equal to 2.5% of the aggregate principal amount of such loans. On the fifth anniversary after initial funding, any remaining amounts outstanding under the Five-Year Facility become due and payable. Additionally, the agreement requires that proceeds from divestitures of the Company’s Tribotecc metal sulfides business and the Company’s minerals-based flame retardants and specialty chemicals businesses, and intended divestiture of its Fine Chemistry Services business, must be used to repay amounts outstanding under the September 2015 Term Loan Agreement. Borrowings under the September 2015 Term Loan Agreement are subject to customary affirmative and negative covenants, including a maximum leverage ratio requirement that is aligned with the maximum leverage ratio requirement of our February 2014 Credit Agreement, as defined below.

Credit Agreement

Our revolving, unsecured credit agreement dated as of February 7, 2014, as amended, (the “February 2014 Credit Agreement”) currently provides for borrowings of up to $1.0 billion and matures on February 7, 2020. Borrowings bear interest at variable rates based on the LIBOR for deposits in the relevant currency plus an applicable margin which ranges from 1.000% to 1.700%, depending on the Company’s credit rating from Standard & Poor’s Ratings Services (“S&P”), Moody’s Investors Services (“Moody’s”) and Fitch Ratings (“Fitch”). The applicable margin on the facility was 1.300% as of December 31, 2015.

Borrowings under the February 2014 Credit Agreement are conditioned upon compliance with the following covenants: (a) consolidated funded debt, as defined in the agreement, must be less than or equal to 3.50 times consolidated EBITDA, as defined in the agreement, (which reflects adjustments for certain non-recurring or unusual items such as restructuring charges, facility divestiture charges and other significant non-recurring items), or herein “consolidated adjusted EBITDA,” as of the end of any fiscal quarter; (b) with the exception of certain liens as specified in the agreement, liens may not attach to assets when the aggregate amount of all indebtedness secured by such liens plus unsecured subsidiary indebtedness, other than indebtedness incurred by our subsidiaries under the February 2014 Credit Agreement, would exceed 20% of consolidated net worth, as defined in the agreement; and (c) with the exception of certain indebtedness as specified in the agreement, subsidiary indebtedness may not exceed the difference between 20% of consolidated net worth, as defined in the agreement, and indebtedness secured by liens permitted under the agreement.

On August 15, 2014, certain amendments were made to the February 2014 Credit Agreement which include the following: (a) an increase in the maximum leverage ratio (as described above) from 3.50 to 4.50 for the first four quarters following the completion of the acquisition of Rockwood, stepping down by 0.25 on a quarterly basis thereafter until reaching 3.50; and (b) requiring subsidiaries of Albemarle that guarantee the 2014 Senior Notes to also guarantee the February 2014 Credit Agreement.

In January 2015, we borrowed $250.0 million under the February 2014 Credit Agreement in connection with the acquisition of Rockwood, and such amount was repaid in full in February 2015. As of December 31, 2015, there were no borrowings outstanding under the February 2014 Credit Agreement.

Commercial Paper Notes

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 February 2014 Credit Agreement is available to repay the Commercial Paper Notes, if necessary. Aggregate borrowings outstanding under the February 2014 Credit Agreement and the Commercial Paper Notes will not exceed the $1.0 billion current maximum amount available under the February 2014 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 December 31, 2015, we had $351.3 million of Commercial Paper Notes outstanding bearing a weighted-average interest rate of approximately 1.07% and a weighted-average maturity of 29 days.

August 2014 Term Loan Agreement and Cash Bridge Facility

On August 15, 2014, we entered into a term loan credit agreement (the “August 2014 Term Loan Agreement”) providing for a tranche of senior unsecured term loans in an aggregate amount of $1.0 billion that were intended to be used as short-term borrowings to fund a portion of the cash consideration for the Rockwood acquisition and pay related fees and expenses. In January 2015, we borrowed and repaid $1.0 billion and $816.5 million, respectively, under the August 2014 Term Loan Agreement. In February 2015, the remaining balance outstanding was repaid in full. The weighted-average interest rate on borrowings under the August 2014 Term Loan Agreement was approximately 1.67%. This agreement matured 364 days following the date of funding, which occurred on January 12, 2015.

On December 2, 2014, we entered into an agreement for a senior unsecured cash bridge facility (the “Cash Bridge Facility”) pursuant to which the lenders thereunder would provide up to $1.15 billion in loans intended to be used as short-term borrowings to fund a portion of the cash consideration for the Rockwood acquisition and pay related fees and expenses, with maturity 60 days following the completion of the Rockwood acquisition. In January 2015, we borrowed and repaid $800.0 million under the Cash Bridge Facility. The weighted-average interest rate on borrowings under the Cash Bridge Facility was approximately 1.67%.

Structuring and underwriting fees of approximately $19.0 million were paid in 2014 in connection with bridge financing arrangements, which are reflected in Other, net, in our consolidated statements of cash flows. These costs were capitalized and were expensed over the term of the facilities or until the date at which permanent financing was obtained and the facilities were eliminated. Accordingly, we expensed $16.7 million in 2014 and $2.3 million in 2015, which is reflected in Other income(expenses), net, in the consolidated statements of income and Other, net, in our consolidated statements of cash flows.

Financing Costs

Debt financing costs paid in 2014 in connection with the 2014 Senior Notes, August 2014 Term Loan Agreement and February 2014 Credit Agreement were $17.6 million. In 2015, we paid approximately $4.5 million of debt financing costs primarily related to the 2014 Senior Notes, the September 2015 Term Loan Agreement and amendments to the February 2014 Credit Agreement.

Other

We have additional uncommitted credit lines with various U.S. and foreign financial institutions that provide for borrowings of up to approximately $257 million at December 31, 2015. Outstanding borrowings under these agreements were $98.9 million and $27.1 million at December 31, 2015 and 2014, respectively. The average interest rate on borrowings under these agreements during 2015, 2014 and 2013 was approximately 0.74%, 0.83% and 0.76%, respectively.

At December 31, 2015 and 2014, we had the ability and intent to refinance our borrowings under our other existing credit lines with borrowings under the February 2014 Credit Agreement. Therefore, the amounts outstanding under those credit lines, if any, are classified as long-term debt at December 31, 2015 and 2014. At December 31, 2015, we had the ability to borrow $648.7 million under our commercial paper program and the February 2014 Credit Agreement.

We believe that as of December 31, 2015, we were, and currently are, in compliance with all of our debt covenants.
