Debt [Abstract]
Debt	3. DEBT At June 30, 2017 and September 30, 2016, our long-term debt of $29,407 and $29,257, respectively, primarily relates to amounts drawn on our revolving credit facility. Our weighted-average annual interest rate on these borrowings was 3.04% at June 30, 2017, and 2.76% at September 30, 2016. At June 30, 2017, we also had $6,493 in outstanding letters of credit and total availability of $43,821 under this facility without violating our financial covenants. On April 10, 2017, we entered into an amendment and restatement to our revolving credit facility (the “Amended Credit Agreement”). Pursuant to the Amended Credit Agreement, our maximum revolver amount increased from $70,000 to $100,000, and the maturity date of the revolving credit facility was extended from August 9, 2019 to August 9, 2021. The Amended Credit Agreement also modified our financial covenants by, among other items: implementing a new covenant that requires the Company to maintain a minimum EBITDA (as defined in the Amended Credit Agreement) that will be tested quarterly on a trailing twelve month basis; increasing the minimum liquidity requirement applicable to the Company from 12.5% to 30% of the maximum revolver amount; raising the Company’s required fixed charge coverage ratio (the “FCCR”) to 1.1:1.0 from 1.0:1.0; and requiring that the FCCR be tested quarterly regardless of the Company’s liquidity levels. The amendment and restatement did not include any changes to interest rates and continues to contain other customary affirmative, negative and financial covenants as well as events of default. On July 14, 2017, and August 2, 2017, we entered into amendments to the Amended Credit Agreement that, respectively, permitted certain transactions related to our acquisition of NEXT Electric, LLC (“NEXT”) and modified our minimum EBITDA requirement under the facility, among other things. See Note 14 – Subsequent Events for further discussion of these amendments. The Company was in compliance with all covenants under the Amended Credit Agreement at June 30, 2017. At June 30, 2017, the carrying value of amounts outstanding under the Amended Credit Agreement approximated fair value, as debt incurs interest at a variable rate. The fair value of the debt is classified as a level 2 measurement.
