FAIR VALUE MEASURMENTS	Dec. 31, 2020
Fair Value Disclosures [Abstract]
Fair Value Measurements	FAIR VALUE MEASUREMENTS Fair value measurements are determined by maximizing the use of observable inputs and minimizing the use of unobservable inputs. The hierarchy places the highest priority on unadjusted quoted market prices in active markets for identical assets or liabilities (Level 1 measurements) and gives the lowest priority to unobservable inputs (Level 3 measurements). The three levels of inputs within the fair value hierarchy are defined in Note 2, Summary of Significant Accounting Policies. While the Company believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date. First Lien Term Loan: The fair value of the First Lien Term Loan is derived from a broker quote on the loans in the syndication (Level 2 inputs). See Note 11, Indebtedness, for further discussion of the carrying amount and fair value of the First Lien Term Loan. Second Lien Notes: The fair value of the Second Lien Notes is derived from a cash flow model that discounted the cash flows based on market interest rates (Level 3 inputs). See Note 11, Indebtedness, for further discussion of the carrying amount and fair value of the Second Lien Notes. Interest rate swaps: The fair values of interest rate swaps are derived from the interest rates prevalent in the market and future expectations of those interest rates (Level 2 inputs). The Company determines the fair value of the investments based on quoted prices from third-party brokers. See Note 12, Derivative Instruments, for further discussion of the fair value of the interest rate swaps. Interest rate caps: The fair values of interest rate caps are derived from the interest rates prevalent in the market and future expectations of those interest rates (Level 2 inputs). The Company determines the fair value of the investments based on quoted prices from third-party brokers. In April 2019, Option Care terminated its interest rate caps. See Note 12, Derivative Instruments, for further discussion of the fair value of the interest rate caps. There were no other assets or liabilities measured at fair value at December 31, 2020 or 2019.
