Summary of Carrying Values and the Estimated Fair Values of Financial Instruments

Derivative Instruments

The Company’s objective in using interest rate derivative instruments is to hedge against interest rate volatility associated with its senior secured credit facilities by converting a portion of its floating rate debt to fixed rate debt. In November 2022, the Company entered into two interest rate swap agreements with Barclays Bank PLC (“Barclays”) to manage interest rate risk related to 2022 Term Loan. Each agreement has a notional amount of $150 million and will expire on October 31, 2025. One agreement swaps variable interest at a rate based on SOFR with a fixed rate of 4.39% and the second with a fixed rate of 4.48%.

At the inceptions of the swap agreements and as of March 31, 2023, both swaps were designated and qualified as cash flow hedges in accordance with ASC 815. Their gain (loss) is recorded in Accumulated other comprehensive income (loss) and then reclassified into Interest expense in the same period in which the hedged transaction affects earnings. As of March 31, 2023, the Company expects to reclass approximately $0.5 million ($0.4 million after-tax) as a reduction to interest expense in the next 12 months.

The following table provides the fair values of the interest rate derivative instruments as well as their classification on the Balance Sheet as of March 31, 2023 and September 30, 2022 (in thousands):

			Fair Value as of
	Fair Value Hierarchy	Balance Sheet Location	March 31, 2023		September 30, 2022
Assets
Interest rate swaps	Level 2	Other current assets	$	546	$	—
Liabilities
Interest rate swaps	Level 2	Other non-current liabilities	$	5,045	$	—

The Company estimates the fair value of interest rate swaps using a valuation model based on observable market data, such as yield curves. Both swaps are classified as Level 2 measurement in the fair value hierarchy.
