[2] These swaps were terminated in April 2025 in connection with the extinguishment of the Trinity Rail Leasing 2017, LLC (“TRL-2017”) promissory notes and the associated refinancing of the amended and restated Trinity Rail Leasing 2023 LLC (“TRL-2023”) term loan agreement. See Note 8 for further information. The swaps had a $6.7 million derivative liability fair value upon termination. In lieu of cash settlement, we incorporated the $6.7 million derivative liability into the terms of the new interest rate swaps, as described in the footnote below, resulting in off-market terms.
[3] In April 2025, we entered into interest rate swaps associated with the amended and restated TRL-2023 term loan agreement. The swaps had a $6.7 million derivative liability fair value at inception, representing the off-market component of the swaps. The off-market value is being ratably amortized into interest expense through the maturity date of the swaps related to the amended and restated TRL-2023 term loan.
