Fair Value Disclosures [Abstract] |
Fair Value of Financial Instruments | Fair Value of Financial Instruments Fair Value Hierarchy The Company measures its financial instruments at fair value. The Company’s cash, cash equivalents, and restricted cash are classified within Level 1 of the fair value hierarchy as they are valued primarily using quoted market prices utilizing market observable inputs. The Company's interest rate swap contracts and credit facilities are classified within Level 2 as the valuation inputs are based on quoted prices or market observable data of similar instruments. The Company's convertible senior notes are classified within Level 2 as the valuation inputs are based on quoted prices in an inactive market on the last day in the reporting period. As of December 31, 2020, the fair value of the convertible senior notes was $782.3 million, compared to their carrying value of $467.2 million, which is net of unamortized discount and debt issuance costs and excludes amounts classified within additional paid-in capital. Refer to Note 9, Debt and Credit Agreements, for further information regarding the Company’s credit facilities and Note 10, Convertible Senior Notes, for further information regarding the Company’s convertible senior notes. Interest Rate Swap Contracts During 2016, the Company entered into an interest rate swap agreement with a combined notional amount of $100.0 million with one counterparty that became effective on June 30, 2016 and matured on April 30, 2019. The swap agreement required the Company to pay a fixed rate of 0.8% and provided that the Company receive a variable rate based on the one month LIBOR rate subject to a LIBOR floor of 0.0%. Amounts payable by or due to the Company were net settled with the respective counterparty on the last business day of each month, commencing July 31, 2016. The Company’s interest rate swap agreement matured during the second quarter of 2019, and, as of December 31, 2020, the Company did not have any outstanding interest rate swap agreements.
