Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives and Hedging Activities	DERIVATIVES AND HEDGING ACTIVITIES Risk Management Objective of Using Derivatives We are exposed to certain risks arising from both our business operations and economic conditions. We manage exposure to a wide variety of business and operational risks through our core business activities. We manage economic risks, including interest rate, liquidity and credit risk primarily by overseeing the amount, sources and duration of debt funding and the use of derivative financial instruments. Specifically, we have entered into derivative financial instruments to manage exposure to interest rate movements that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. Our derivative financial instruments are used to manage differences in the amount, timing and duration of our known or expected cash receipts and known or expected cash payments principally related to our investments and borrowings. Cash Flow Hedges of Interest Rate Risk Our purpose for using interest rate derivatives is to add stability to interest expense and to manage our exposure to interest rate movements. During the year ended December 31, 2020, we used interest rate swaps to hedge the variable cash flows associated with existing variable-rate debt. Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. We do not use derivatives for trading or speculative purposes and we currently do not have any derivatives that are not designated as hedges. As of December 31, 2020, we have not posted any collateral related to these agreements. During the year ended December 31, 2020, we terminated our two existing interest rate swaps and our forward interest rate swap and simultaneously entered into a new forward interest rate swap beginning July 30, 2021. We settled the terminated swaps by making a cash payment of $17.8 million. This payment is classified within cash flows from operating activities within the Consolidated Statements of Cash Flows for the year ended December 31, 2020. The unrealized loss included in accumulated other comprehensive loss associated with the terminated swaps of $17.8 million at the time of termination will be amortized to interest expense over the course of the originally scheduled settlement dates of the terminated swaps. During the year ended December 31, 2020, we amortized $1.3 million of the unrealized loss to interest expense, net. The new forward interest rate swap has a beginning notional amount of $200.0 million, a fixed rate of 0.51% and a maturity date of April 15, 2030. Upon commencement, this forward swap will serve to hedge substantially all of the variable cash flows on our Term Loan until its maturity and if extended. The assets and liabilities associated with the forward interest rate swap are included in other long-term assets and other current liabilities on the Consolidated Balance Sheets at their fair value amounts as described in Note 10, Fair Value Measurements. The changes in the fair value of derivatives designated and that qualify as cash flow hedges are recorded in other comprehensive income, net of tax on the Consolidated Statements of Operations and Comprehensive Income and in accumulated other comprehensive income on the Consolidated Balance Sheets and subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. We had no such changes during the years ended December 31, 2020 or 2019. Amounts reported in accumulated other comprehensive income related to derivatives will be reclassified to interest expense, net as interest payments are made on our variable-rate debt. Over the next twelve months, we estimate that an additional $3.5 million will be reclassified as an increase to interest expense, net. LIBOR is used as a reference rate for our interest rate swap agreements we use to hedge our interest rate exposure. During the year ended December 31, 2020, we adopted ASU 2020-04, Reference Rate Reform: Facilitation of the Effects of Reference Rate Reform on Financial Reporting (Topic 848). The purpose of this guidance is to provide relief for impacted areas as it relates to impending reference rate reform. We elected to apply the hedge accounting expedients related to probability and the assessments of effectiveness for future LIBOR-indexed cash flows to assume that the index upon which future hedged transactions will be based matches the index on the corresponding derivatives. Application of these expedients preserves the presentation of derivatives consistent with past presentation.
