Fair Value Disclosures [Abstract] |
Fair Value Measurements | Fair Value Measurements Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset and liability in an orderly transaction between market participants at the measurement date. We estimate the fair value of our assets and liabilities when required using an established three-level hierarchy in accordance with ASC 820. The fair value of our financial assets and liabilities is determined by reference to market data and other valuation techniques as appropriate. We believe the fair value of our financial instruments, which are principally cash and cash equivalents, restricted cash, accounts receivable, other current assets, accounts payable and accrued liabilities, approximates their recorded values. Our assets and liabilities measured at fair value on a recurring basis are described below. Derivative Financial Instruments We record derivative financial instruments on the balance sheet at their respective fair values. As described in Note 1, during the first quarter of 2018, we adopted ASU 2017-12. As of December 31, 2018, we held the following derivative instruments that were accounted for pursuant to ASC 815: Interest Rate Swap Contracts We currently use interest rate swap contracts as described below to manage exposure to interest rate fluctuations by reducing the uncertainty of future cash flows on our variable rate debt. Our interest rate swaps that we held as of December 31, 2017 expired in January 2018. In February 2018, we entered into interest rate swap contracts to hedge a portion of our interest expense associated with our variable rate debt to effectively fix the interest rate that we pay. These interest rate swap contracts are designated as cash flow hedges under ASC 815. We pay interest at a weighted-average fixed rate of 2.4418% and receive interest at a variable rate equal to one-month LIBOR. The total notional amount of interest rate swaps outstanding was $800.0 million as of December 31, 2018. These hedges mature in February 2022. These hedges are highly effective in offsetting changes in our future expected cash flows due to the fluctuation in the one-month LIBOR rate associated with our variable rate debt. We qualitatively monitor the effectiveness of these hedges on a quarterly basis. As a result of the effective matching of the critical terms on our variable rate interest expense being hedged to the hedging instruments being used, we expect these hedges to remain highly effective. All gains and losses from these hedges are recorded in Other comprehensive income (loss) until the future underlying payment transactions occur. Any realized gains or losses resulting from the hedges are recognized (together with the hedged transaction) as interest expense. We estimate the fair value of our interest rate swap contracts by discounting the future cash flows of both the fixed rate and variable rate interest payments based on market yield curves. The inputs used to measure the fair value of our interest rate swap contracts are categorized as Level 2 in the fair value hierarchy as established by ASC 820. The following table shows the gains (losses) and interest expense on our interest rate swap contracts:
|  | Year Ended December 31,
|  | 2018 |  | 2017 |  | 2016
Gains (losses) recorded in accumulated other comprehensive loss, net of tax |  | $ | 0.1 |  |  | $ | (4.2 | ) |  | $ | (3.0 | )
Interest expense recorded related to interest rate swap contracts |  | 2.6 |  |  | 7.0 |  |  | 8.2 |
We do not expect to reclassify material amounts from Accumulated other comprehensive loss to interest expense in the next twelve months. The following table shows the effect of interest rate swap contracts designated as cash flow hedges on the consolidated statements of operations and comprehensive loss:
|  | Year Ended December 31, 2018
|  | Interest expense
Total amounts of expense line item presented in the statements of operations and comprehensive loss in which the effects of cash flow hedges are recorded |  | $ | (597.2 | )

Derivative designated as hedging instrument |  | 14.0 |
Cross-Currency Interest Rate Swaps In connection with the February 2018 Refinancing (see Note 16), we entered into certain cross-currency interest rate swap agreements to achieve more attractive interest rates by effectively converting $460.0 million of our fixed-rate U.S. Dollar-denominated 2025 Secured Notes, including the semi-annual interest payments through October 2023, to fixed-rate Euro-denominated debt, with a fixed annual weighted average interest rate of approximately 2.946%. We have designated these cross-currency interest rate swap agreements as a net investment hedge of our investments in certain of our international subsidiaries that use the Euro as their functional currency in order to reduce the volatility in our operating results caused by the changes in foreign currency exchange rates of the Euro relative to the U.S. Dollar. We use the spot method to measure the effectiveness of our net investment hedge. Under this method, for each reporting period, the change in the fair value of the $460.0 million cross-currency interest rate swaps is reported in foreign currency translation gain (loss) in Accumulated other comprehensive loss. The cross-currency basis spread (along with other components of the cross-currency swaps’ fair value excluded from the spot method effectiveness assessment) are amortized and recorded to interest expense. We evaluate the effectiveness of our net investment hedge at the beginning of each quarter. The following table shows the fair value of our hedges:
| Balance Sheet Line Item |  | December 31, 2018 |  | December 31, 2017
Interest rate swaps(1)(3) | Other assets/(accrued liabilities) |  | $ | 0.2 |  |  | $ | (0.2 | )
Cross-currency interest rate swaps(2)(3) | Other assets |  | 18.0 |  |  | — |
(1) The gains (loss) of $0.2 million, ($0.2 million) and ($6.9 million) for the years ended December 31, 2018, 2017 and 2016, respectively, are reflected in Derivative financial instrument unrealized gain (loss), net of tax in Other comprehensive income. (2) The gain of $18.0 million for the year ended December 31, 2018 is reflected in Foreign currency translation loss, net of tax in Other comprehensive income. (3) The inputs used to measure the fair value of our interest rate swap contracts are categorized as Level 2 in the fair value hierarchy.
Net Investment Non-derivative Hedge - 2026 Secured Euro Notes For the fourth quarter of 2018, we designated $155.0 million of our 2026 Secured Euro Notes as a net investment non-derivative hedge of our investments in certain of our international subsidiaries that use the Euro as their functional currency in order to reduce the volatility in our results caused by the changes in foreign currency exchange rates of the Euro relative to the U.S. Dollar. We use the spot method to measure the effectiveness of our net investment non-derivative hedge. Under this method, for each reporting period, the change in the hedged portion of the carrying value of the 2026 Secured Euro Notes due to remeasurement is reported in foreign currency translation gain (loss) in Other comprehensive income, and the remaining remeasurement change is recognized in Loss on remeasurement of debt in our consolidated statements of operations and comprehensive loss. We evaluate the effectiveness of our net investment non-derivative hedge at the beginning of each quarter and the inputs used to measure the fair value of this non-derivative hedge are categorized as Level 2 in the fair value hierarchy. Contingent Acquisition Consideration Liabilities In connection with our 2017 and 2018 acquisitions, we have recorded certain contingent acquisition consideration liabilities, of which the values are primarily based on reaching certain earnings-based metrics, with a maximum payout of up to $49.2 million as of December 31, 2018. The related liabilities were recorded at fair value on the acquisition date as part of the consideration transferred and are remeasured each reporting period. The inputs used to measure the fair value of our liabilities are categorized as Level 3 in the fair value hierarchy. We remeasured contingent acquisition consideration at each reporting period. These remeasurements included increases to the projected earnings-based measures and also the probability of achievement (categorized as Level 3 in the fair value hierarchy as established by ASC 820), which resulted in increases to the calculated fair value of contingent acquisition consideration by $18.0 million, $8.4 million, and $2.3 million, for the first, third, and fourth quarters of 2018, respectively. These changes were recorded in Restructuring and other. Contingent acquisition consideration liabilities as of December 31, 2018 and 2017 were $44.6 million and $7.5 million, respectively, of which $22.1 million as of December 31, 2018 is included in accrued liabilities with the remaining balance included in other long-term liabilities and the entire balance as of December 31, 2017 included in other long-term liabilities. We did not have assets and liabilities measured at fair value on a non-recurring basis as of December 31, 2018 other than those described in Note 9.
