[1] Cash paid for interest on debt was $47.5 million during 2023, $34.3 million during 2022, and $25.9 million during 2021.

[2] The weighted-average interest rate on total debt (including unamortized debt issuance costs and commitment fees) was 9.9% for 2023, 9.3% for 2022 and 6.4% for 2021. The estimated fair value of total debt and finance leases was $349.8 million as of December 31, 2023 and $301.8 million as of December 31, 2022. The fair value of debt was estimated by discounting the future cash flows using rates currently available for debt of similar terms and maturity, which is a Level 2 measurement. Refer to Note 14 – Fair Value Measurements for additional information.

[3] Represents the weighted-average interest rate in effect as of the end of the respective periods, including any applicable margin. The interest rates do not include amortization of debt issuance costs, commitment fees, or any expense or income related to the Interest Rate Cap as discussed in Note 13 - Derivative.
