Derivative Instruments and Hedging Activities Disclosure [Abstract] |
Fair Value Measurements | Fair Value Measurements 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, 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. Interest rate swap contracts We record derivative financial instruments on the balance sheet at their respective fair values. We currently use swap contracts as described below to mitigate gains or losses associated with the change in expected cash flows due to fluctuations in interest rates on our variable rate debt. We hedge a portion of our interest expense associated with our variable rate debt to effectively fix the interest rates that we pay. We have interest rate swap contracts designated as cash flow hedges under ASC 815. Under these hedges, we pay interest at a weighted-average fixed rate of 2.151% and receive interest at the greater of 1% or the prevailing three-month LIBOR rate. The total notional amount of interest rate swaps outstanding was $700.0 million as of both March 31, 2017 and December 31, 2016. These hedges are highly effective in offsetting changes in our future expected cash flows due to the fluctuation in the three-month LIBOR rate associated with our variable rate debt. The effectiveness of these hedges is measured quarterly on a retrospective 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 have not measured any hedge ineffectiveness through the date of our debt refinancing transactions as described in Note 10. Subsequent to the debt refinancing, we have measured ineffectiveness totaling $0.6 million as a result of the terms of our swaps no longer matching critical terms with the hedged forecasted interest payments; however, those hedges remain highly effective as measured by our regression analysis. We expect our interest rate swaps to continue 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 will be 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. The following table shows the (gains) losses on our interest rate swap contracts:

We expect to reclassify additional losses of $4.6 million from accumulated other comprehensive loss to interest expense in the next twelve months. The following table shows the fair value of our hedges:
