Accounting for Derivative Instruments and Hedging Activities [Abstract] |
Accounting for Derivative Instruments and Hedging Activities | Accounting for Derivative Instruments and Hedging Activities The Company uses derivative instruments to manage foreign exchange risk on the Sterling Notes, and does not hold or issue derivative instruments for speculative trading purposes. Cross-currency derivative instruments are used to effectively convert £1.275 billion aggregate principal amount of fixed-rate British pound sterling denominated debt, including annual interest payments and the payment of principal at maturity, to fixed-rate U.S. dollar denominated debt. The cross-currency swaps have maturities of June 2031 and July 2042. The Company is required to post collateral on the cross-currency derivative instruments when the derivative contracts are in a liability position. In April 2019, the Company entered into a collateral holiday agreement for 60% of both the 2031 and 2042 cross-currency swaps, which eliminates the requirement to post collateral for three years, as well as a ten year collateral cap on the remaining 40% of the cross-currency swaps which limits the required collateral posting on that 40% of the cross-currency swaps to $150 million. In March 2021, the collateral holiday for 20% of the swaps was extended to November 2022 in consideration for the Company's agreement to post collateral over a threshold amount on that 20% portion of the swaps from March 2021 through October 2021. The fair value of the Company's cross-currency derivatives was $206 million and $184 million and is included in other long-term liabilities on its consolidated balance sheets as of June 30, 2021 and December 31, 2020, respectively. The Company’s derivative instruments are not designated as hedges and are marked to fair value each period, with the impact recorded as a gain or loss on financial instruments in the consolidated statements of operations in other income (expenses), net. While these derivative instruments are not designated as hedges for accounting purposes, management continues to believe such instruments are closely correlated with the respective debt, thus managing associated risk. The effect of financial instruments are recorded in other income (expenses), net in the consolidated statements of operations and consisted of the following.
