Derivative Instruments and Hedging Activities Disclosure [Abstract]

As part of our interest rate risk management strategy, we have entered into interest rate swaps, which we designated as cash flow hedges, to mitigate variability in interest payments on a portion of our variable-rate debt (Note 12). In March 2023, we modified our September 2022 interest rate swap agreement to utilize SOFR as the reference rate in the agreement. Information regarding our accounting for this modification can be found in Note 2. In June 2023, we entered into a 3-year interest rate swap agreement with a variable notional amount that resets quarterly. Our derivative instruments were comprised of the following:


							June 30, 2023		December 31, 2022
(in thousands)	Notional amount		Interest rate		Maturity	Balance sheet location	Fair value asset / (liability)		Fair value asset / (liability)
June 2023 amortizing interest rate swap:
	$	298,729	4.249	%	June 2026	Other non-current assets	$	1,358	$	—
March 2023 interest rate swap:
	200,000		4.003	%	March 2026	Other non-current assets	2,850		—
September 2022 interest rate swap:
	300,000		3.990	%	September 2025	Other non-current assets	4,807		2,409
July 2019 interest rate swap:
	200,000		1.798	%	March 2023	Other current assets	—		1,184

Changes in the fair values of the interest rate swaps are recorded in accumulated other comprehensive loss on the consolidated balance sheets and are subsequently reclassified to interest expense as interest payments are made on the variable-rate debt. The fair values of the derivatives are calculated based on the applicable reference rate curve on the date of measurement. The cash flow hedges were fully effective as of June 30, 2023 and December 31, 2022, and their impact on

consolidated net income and the consolidated statements of cash flows was not material. We also expect that the amount that will be reclassified to interest expense during the next 12 months will not be material.
