Derivative Financial Instruments and Hedging Activities

Risk Management Objective of Using Derivatives

Our objectives in using interest rate derivatives are to add predictability to interest expense and to manage our exposure to interest rate movements. To accomplish these objectives, we primarily use interest rate swaps and treasury locks as part of our interest rate management strategy. Interest rate swaps primarily involve the receipt of variable-rate and fixed-rate amounts from a counterparty in exchange for us making fixed-rate or variable-rate payments over the life of the agreements without exchange of the underlying notional amounts.

Changes in fair value of derivatives designated as cash flow hedges are recognized in accumulated other comprehensive income and subsequently reclassified into earnings as an increase or decrease to interest expense. During the three months ended March 31, 2024, we reclassified gains of $2.1 million out of accumulated other comprehensive income into interest expense. During the three months ended March 31, 2023, we reclassified $4.2 million out of accumulated other comprehensive income, net into interest expense. As of March 31, 2024, we estimate that during the next 12 months, we will reclassify into earnings approximately $6.1 million of the unrealized gain in accumulated other comprehensive income.

Changes in fair value of derivatives not designated in a hedge relationship, or economic hedges, are recognized in gain (loss) on derivative instruments, net, in our condensed consolidated statements of operations once realized. During the three months ended March 31, 2024 and 2023, gain (loss) on derivative instruments was $9.6 million and $(2.1) million, respectively.

During the three months ended March 31, 2024, we terminated five interest rate swap positions not designated as hedging instruments. Two of the terminated instruments were pay-fixed, receive-floating interest rate swaps with a notional value of $80 million, and two were offsetting pay-floating, receive-fixed interest rate swaps with a notional value of $80 million. One of the terminated instruments was a forward starting interest rate swap entered into in anticipation of additional fixed-rate property debt with a notional value of $50 million and was replaced by a new forward starting interest rate swap with a notional value of $42 million. Additionally, AIR entered into one forward starting interest rate swap with a notional value of $51.7 million, and restructured one pay-fixed, receive-floating interest rate swap, to better align the maturity date with the related term loans. As a result of these transactions, AIR received $6.2 million in cash during the three months ended March 31, 2024.

During the three months ended March 31, 2024, AIR entered into three pay-fixed, receive floating interest rate swaps, with a notional value of $200 million, economically hedging $200 million of our $260 million revolving credit facility borrowings outstanding as of March 31, 2024, at 4.9%.

As of March 31, 2024, AIR had a notional value of $675 million of pay-fixed, receive-floating interest rate swaps that are not designated as hedging instruments, and a notional value of $94 million of forward starting interest rate swaps that are not designated as hedging instruments. Accordingly, the changes in the fair value of these derivatives are recognized in gain (loss) on derivative instruments, net, in our condensed consolidated statements of operations.
