In January 2023, we entered into a $400.0 million interest rate swap to manage the interest rate risk associated with our floating-rate, SOFR-based borrowings, including borrowings on the Revolving Credit Facility and the AR Facility. We designated our interest rate swap as a cash flow hedge in accordance with ASC 815, Derivatives and Hedging. There is no ineffectiveness related to our hedge.

The components of the unrealized gain (loss) on designated cash flow hedge related to changes in the fair value of our interest rate swap are as follows (in millions):


	Three Months Ended March 31,
	2024		2023
Change in fair value of interest rate swap	$	3.9	$	(1.6)
Tax benefit (expense)	(0.9)		0.4
Unrealized gain (loss) on designated cash flow hedge	$	3.0	$	(1.2)

On all transactions where we are exposed to counterparty risk, we analyze the counterparty’s financial condition prior to entering into an agreement, establish limits, and monitor the appropriateness of these limits on an ongoing basis. We primarily deal with financial institutions when entering into financial derivatives on commodities. We have entered into Master ISDAs that allow for netting of swap contract receivables and payables in the event of default by either party. Additionally, we have entered into FCDTCs that allow for netting of futures contract receivables and payables in the event of default by either party. If our counterparties failed to perform under existing commodity swap and futures contracts, the maximum loss on our gross receivable position of $107.3 million as of March 31, 2024 would be reduced to $4.2 million due to the offsetting of gross fair value payables against gross fair value receivables as allowed by the ISDAs and the FCDTCs.
