Fair Value Disclosures [Abstract]

Schedule of financial assets and liabilities and other fair value disclosures by fair value hierarchy

Fair value on recurring basis

Consistent with the fair value hierarchy, we categorized our financial assets and liabilities as follows (in thousands):

			As of September 30,
	Classification	Pricing Category	2022		2021
Financial Assets
Interest rate caps	Other assets	Level 2	$	3,860	$	35
Foreign exchange contracts	Other current assets	Level 2		294		—
Total assets			$	3,860	$	35
Financial Liabilities
Foreign exchange contracts	Accrued liabilities	Level 2	$	79	$	—

The fair value for interest rate caps and foreign exchange contracts were measured using widely accepted valuation techniques, such as discounted cash flow analyses and observable inputs, such as market interest rates and foreign exchange rates.
