Cash Flow Hedging

Cash Flow Hedges Not Designated as Hedging Instruments

The Company uses non-designated cash flow hedges including interest rate swap agreements and interest rate cap agreements to minimize its exposure to interest rate fluctuations on variable rate debt borrowings. Interest rate swaps involve the exchange of fixed and variable rate interest payments and do not represent an actual exchange of the underlying notional amounts between parties. Interest rate caps provide that the counterparty will pay the purchaser at the end of each contractual period in which the index interest rate exceeds the contractually agreed upon cap rate.

In the first quarter of 2024, the Company entered into a forward starting non-amortizing interest rate swap to convert variable rate debt to fixed rate debt. The interest rate swap has a notional amount of $200.0 million resulting in interest payments based on an average fixed rate per swap of 4.3030%, plus the applicable margin per the requirements in the Credit Agreement. The interest rate swap expires in July 2025.

In the first quarter of 2023, the Company entered into three forward starting non-amortizing interest rate swaps to convert variable rate debt to fixed rate debt. The interest rate swaps have notional amounts of $150.0 million, $150.0 million and $100.0 million resulting in interest payments based on an average fixed rate per swap of 3.6875%, 3.6500% and 3.5095%, respectively, plus the applicable margin per the requirements in the Credit Agreement. The interest rate swaps expire in March 2027.

In the second quarter of 2022, the Company entered into two interest rate cap agreements to limit exposure to interest rate risk on variable rate debt. The interest rate caps each have a cap rate of 3.0% with notional amounts of $200.0 million and $175.0 million and deferred premiums of $6.7 million and $5.3 million, respectively. The deferred premiums will be paid on a monthly basis over the term of the respective interest rate cap. The interest rate caps expire in May 2026.

In the second quarter of 2022, the Company entered into three forward starting non-amortizing interest rate swaps to convert variable rate debt to fixed rate debt. The interest rate swaps have notional amounts of $175.0 million, $115.0 million and $85.0 million resulting in interest payments based on an average fixed rate per swap of 2.9185%, 2.8520% and 2.8605%, respectively, plus the applicable margin per the requirements in the Credit Agreement. The interest rate swaps expire in May 2026.

The fair value of the Company's interest rate swaps and interest rate caps are impacted by the credit risk of both the Company and its counterparties. The Company has agreements with its derivative financial instrument counterparties that contain provisions providing that if the Company defaults on the indebtedness associated with its derivative financial instruments, then the Company could also be declared in default on its derivative financials instruments obligations. In addition, the Company minimizes nonperformance risk on its derivative instruments by evaluating the creditworthiness of its counterparties, which are limited to major banks and financial institutions.

The Company does not apply hedge accounting to the interest rate swaps and interest rate caps and records all mark-to-market adjustments directly to "Other income, net" in the Consolidated Statements of Operations. The fair values of the interest rate swaps and interest rate caps are categorized as Level 2 in the fair value hierarchy as they are based on well-recognized financial principles and available market data.

As of December 31, 2024, the fair values of the interest rate swaps and interest rate caps are recorded in the Consolidated Balance Sheets as follows:

In connection with the Merger, the carrying values of the Company's long-term debt and other financing arrangements include fair value adjustments as of the Merger Date. The fair value of our long-term debt was based on closing or estimated market prices of the Company’s debt at December 31, 2024 and December 31, 2023, which is considered Level 2 of the fair value hierarchy. The fair value of the other financing arrangements was calculated using a discounted cash flow model that incorporates current borrowing rates for obligations of similar duration, which is considered Level 3 of the fair value hierarchy. As of December 31, 2024, the current borrowing rate was estimated by applying the Company's credit spread to the risk-free rate for a similar duration borrowing.
