Financial instruments and fair value measurements | ( 6 ) Financial Instruments and Fair Value Measurements Our financial instruments include cash and cash equivalents, trade accounts receivable, accounts payable, debt and an amount due to Varietal under the ITRA. Except for the amount due to Varietal, these financial instruments are held or issued by a number of institutions, which reduces the risk of material non-performance. Assets and Liabilities for which Fair Value is Only Disclosed The carrying amount of cash and cash equivalents is the same as its fair value and is a Level 1 measurement. The carrying amounts for trade accounts receivable and accounts payable approximate fair value due to their short-term nature and are Level 2 measurements. The following table presents the carrying amounts and fair values of debt instruments (in millions): March 31, 2016 December 31, 2015 Carrying amount Fair value Carrying amount Fair value Accounts receivable securitization facility $ 118.2 $ 118.2 $ 38.0 $ 38.0 Senior credit facility: Term A loan 892.8 895.3 903.9 901.5 Term B loan 517.9 521.5 494.8 500.5 4.625% senior notes 565.3 572.0 538.6 536.5 Other debt 13.9 13.9 13.7 13.7 The fair values of debt instruments are based on quoted market prices and standard pricing models that take into account the present value of future cash flows, which are Level 2 measurements. At March 31, 2016 and December 31, 2015 , the amount due to Varietal under the ITRA (see Note 11 ) had carrying amounts of $85.0 million and $163.1 million , respectively, and fair values of $70.5 million and $147.6 million , respectively. The fair values were estimated using a combination of observable and unobservable inputs using an income-based approach, a Level 3 measurement. Recurring Fair Value Measurements with Significant Unobservable Inputs The following table presents changes in contingent consideration liabilities, which are measured at fair value on a recurring basis using Level 3 measurements (in millions): Three months Beginning balance $ 21.0 Acquisitions 7.5 Loss from changes to estimated fair value 0.2 Settlements in cash (1.8 ) Currency translation (0.2 ) Ending balance $ 26.7 Certain of the business acquisitions we completed entitle the sellers to contingent consideration if earnings targets are met during a period of time following the acquisition. We estimate their fair value using the average of probability-weighted potential earn-out payments specified in the purchase agreements, ranging in the aggregate from approximately $1 million to $34 million for all open earn-outs a t March 31, 2016 . The significant assumptions used in these calculations include forecasted results and the estimated likelihood for each performance scenario. Derivative Instruments and Hedging Activities We engage in hedging activities to reduce our exposure to changes in variable interest rates and foreign currency exchange rates. Our hedging activities are designed to manage specific risks according to our strategies, as summarized below, which may change from time to time. Our hedging activities consist of the following: • Variable interest rate hedging — Beginning in April 2016, we hedge the variable base interest rate of a portion of our term A loan using interest rate swaps; • Net investment hedging — We hedge a portion of our net investment in euro-denominated foreign operations using our 4.625% senior notes and a portion of our term B loan; • Economic hedge — We experience opposite foreign currency exchange rate effects related to a euro-denominated intercompany loan and the unhedged portion of our term B loan. The currency effects for these non-derivative instruments are recorded through earnings in the period of change and substantially offset one another; and • Other hedging activities — Some of our subsidiaries hedge short-term foreign-denominated business transactions and intercompany financing transactions using foreign currency forward contracts. These activities were not material to our consolidated financial statements. Variable Interest Rate Hedging In April 2016, we entered into two interest rate swaps that we designated as cash flow hedges of the variable LIBOR rate on our term A loan. Beginning April 2016, we swapped LIBOR for a 1.00% fixed rate on $375.0 million of our term A loan. Beginning September 2016, we will swap LIBOR for a 1.05% fixed rate on an additional $125.0 million of our term A loan. Both interest rate swaps mature on September 28, 2020. We expect that these hedges will be highly effective, therefore changes to the fair value of the interest rate swaps, which otherwise would be recognized in earnings, will be deferred as accumulated other comprehensive income or loss. Net Investment Hedging We have designated €370.0 million of our term B loan and all €503.8 million of our 4.625% senior notes as hedges to protect a portion of our net investment in euro-denominated foreign operations from the impact of changes in the euro to U.S. dollar exchange rate. As a result of the hedge designations, the net foreign currency remeasurement gain or loss on the hedging instruments, which otherwise would be recognized in earnings, is deferred as accumulated other comprehensive income or loss. That deferred net gain or loss equally offsets the net unrealized gain or loss that is recognized in other comprehensive income or loss from the translation of the hedged portion of our net investment in euro-denominated foreign operations. The hedge has no other impact to our financial position, financial performance or cash flows. Tabular Disclosures The following table presents the balance sheet classification and fair value of liability instruments in hedging relationships, all of which are Level 2 measurements (in millions): Type of hedging relationship Balance sheet classification March 31, 2016 December 31, 2015 €370.0 of term B loan Net investment Debt, net of current portion 419.5 402.6 €503.8 of 4.625% senior notes Net investment Debt, net of current portion 572.0 536.5 The following table presents information about the net unrealized gain (loss) recognized in other comprehensive income or loss resulting from liability instruments in hedging relationships and hedged items (in millions): Type of hedging relationship Description Three months ended March 31, 2016 2015 €873.8 of net investment in foreign operations Net investment Hedged item $ 45.8 $ 2.7 €370.0 of term B loan Net investment Hedging instrument (19.4 ) — €503.8 of 4.625% senior notes Net investment Hedging instrument (26.4 ) (2.7 ) We determined that all of our hedges were fully effective for the three months ended March 31, 2016 and 2015 . No amounts were recognized in or reclassified to earnings as a result of net investment hedging. |
