| Derivative Instruments and Hedging Activities Disclosure [Abstract] | |
| Derivative financial instruments | Derivative financial instruments We have entered into interest rate swaps, which we designated as fair value hedges, to hedge against changes in the fair value of a portion of our long-term debt. At the time we entered into these swaps in 2012, we were targeting a mix of fixed and variable rate debt, where we receive a fixed rate and pay a variable rate based on the London Interbank Offered Rate (LIBOR). The interest rate swaps related to our long-term debt due in 2020 have a notional amount of $200,000 and meet the criteria for using the short-cut method for a fair value hedge based on the structure of the hedging relationship. As such, changes in the fair value of the derivatives and the related long-term debt are equal. The fair value of these interest rate swaps was included in other non-current liabilities in the consolidated balance sheets and was $109 as of September 30, 2016 and $4,842 as of December 31, 2015. As the short-cut method is being used to account for these hedges, the consolidated balance sheets included a decrease in long-term debt of $109 as of September 30, 2016 and $4,842 as of December 31, 2015 due to fair value adjustments. |
