(1)Carrying values of long-term debt balances are before reductions for debt issuance costs and original issue discount of $31.8 million and $45.3 million as of December 31, 2022 and December 31, 2021, respectively.

Fair values of the interest rate swap agreements are determined using significant inputs, including LIBOR forward curves, which are considered Level 2 observable market inputs.

The carrying value of cash and cash equivalents, accounts receivable, accounts payable, and accrued liabilities approximates fair value because of the short maturity of these instruments. There were no assets or liabilities measured at fair value on a non-recurring basis as of December 31, 2022 or December 31, 2021.
