FAIR VALUE MEASUREMENTS
FAIR VALUE MEASUREMENTS	NOTE N — FAIR VALUE MEASUREMENTS Financial Instruments In March 2018, we refinanced our credit facilities with the Credit Agreement. The carrying value (excluding unamortized discounts and debt issuance costs of $9.3 million) of our outstanding term loan as of March 31, 2019 was $500.0 million compared to its fair value of $498.7 million. The carrying value of our outstanding term loan as of December 31, 2018 (excluding unamortized discounts and debt issuance costs of $9.4 million) was $501.2 million compared to its fair value of $491.2 million. Our estimates of fair value are based on a discounted cash flow model and indicative quote using unobservable inputs, primarily, our risk-adjusted credit spread, which represents a Level 3 measurement. As of March 31, 2019 and December 31, 2018, we had no amounts outstanding on our revolving credit facility. In March 2018, we entered into interest rate swap agreements with notional values of $325.0 million at inception, which reduces $12.5 million annually until the swaps mature on March 6, 2024. The notional value outstanding as of March 31, 2019 was $312.5 million. The interest rate swap agreements are designated as cash flow hedges and are measured at fair value based on inputs other than quoted market prices that are observable, which represents a Level 2 measurement. See Note M - “Debt” and Note O - “Derivative Financial Instruments” for further information. The carrying value of our Seller Notes as of March 31, 2019 and December 31, 2018 was $7.4 million and $4.5 million, respectively. We believe that the carrying value of the Seller Notes approximates their fair values based on a discounted cash flow model using unobservable inputs, primarily, our credit spread for subordinated debt, which represents a Level 3 measurement.
