Debt [Abstract]
Debt	3. DEBT At June 30, 2018, and September 30, 2017, our long-term debt of $29,634 and $29,434, respectively, primarily related to amounts drawn on our revolving credit facility. Our weighted-average annual interest rate on these borrowings was 3.74% at June 30, 2018, and 3.04% at September 30, 2017. At June 30, 2018, we also had $6,928 in outstanding letters of credit and total availability of $47,231 under this facility without violating our financial covenants. On July 23, 2018, we entered into the Third Amendment (the “Amendment”) to our Second Amended and Restated Credit and Security Agreement (as amended, the “Credit Agreement”). Pursuant to the Amendment, we will be required to comply with the minimum EBITDA financial covenant of the Credit Agreement in a given quarter only if our Excess Availability (as defined in the Credit Agreement) in the immediately following quarter, as tested monthly during that quarter, falls below $30,000. If, in a subsequent quarter, Excess Availability levels return to or exceed the contractual threshold, then the Company will no longer be required to comply with the minimum EBITDA financial covenant, so long as Excess Availability remains above the threshold. There have been no other changes to the financial or other covenants disclosed in Item 7 of our Annual Report on Form 10-K for the year ended September 30, 2017. The Company was in compliance with the financial covenants as of June 30, 2018. At June 30, 2018, the carrying value of amounts outstanding on our revolving credit facility approximated fair value, as debt incurs interest at a variable rate. The fair value of the debt is classified as a Level 2 measurement.
