At September 30, 2019, we had no outstanding borrowings under our revolving credit facility, $6,468 in outstanding letters of credit and $93,532 available to us under our revolving credit facility with Wells Fargo Bank, N.A. ("Wells Fargo"). All amounts outstanding under our revolving credit facility are due and payable in September 2024, upon expiration of our revolving credit facility, and all amounts described as available are available without triggering our financial covenant under the Amended Credit Agreement (as defined below).

Our interest rate on our outstanding borrowings under our revolving credit facility was 4.25% at September 30, 2018. For the years ended September 30, 2019, 2018 and 2017, we incurred interest expense of $1,857, $1,946 and $1,702, respectively.

The Revolving Credit Facility

We maintain a $100,000 revolving credit facility with Wells Fargo that matures in September 2024, pursuant to a Second Amended and Restated Credit and Security Agreement with Wells Fargo Bank dated as of April 10, 2017, which was amended on July 14, 2017, August 2, 2017, July 23, 2018, May 17, 2019 and September 6, 2019 (as amended, the “Amended Credit Agreement”). The Fourth Amendment to the Second Amended and Restated Credit and Security Agreement, which was entered into on May 20, 2019, permits the Company to repurchase up to 1.0 million additional shares of common stock pursuant to its previously authorized stock repurchase program for an aggregate purchase price (including for any remaining shares under the previous share repurchase authorization) not to exceed $25,000. The Fifth Amendment to the Second Amendment and Restated Credit and Security Agreement, which was entered into on September 6, 2019, reduced the interest rate margin applicable to borrowings by 50 basis points, removed the Company's minimum EBITDA financial covenant, granted pre-approval for acquisitions meeting certain conditions with an aggregate purchase price of up to $25,000, and reduced the minimum liquidity covenant from 30% to 20% of the maximum revolver amount.

Terms of the Amended Credit Agreement

The Amended Credit Agreement contains other customary affirmative, negative and financial covenants, as well as events of default.

As of September 30, 2019, we were in compliance with the financial covenants under the Amended Credit Agreement, requiring that we maintain:

• a Fixed Charge Coverage Ratio (as defined in the Amended Credit Agreement), measured quarterly on a trailing four-quarter basis at the end of each quarter, of at least 1.1 to 1.0; and

• minimum Liquidity (as defined in the Amended Credit Agreement) of at least twenty percent (20%) of the Maximum Revolver Amount (as defined in the Amended Credit Agreement), or $20,000; with, for purposes of this covenant, at least fifty percent (50%) of our Liquidity comprised of Excess Availability (as defined in the Amended Credit Agreement).

At September 30, 2019, our Liquidity was $112,467 and our Excess Availability was $93,532 (or greater than 50% of minimum Liquidity), our Fixed Charge Coverage Ratio was 4.7:1.0.

Our Fixed Charge Coverage Ratio is calculated as follows (with capitalized terms as defined in the Amended Credit Agreement): (i) our trailing twelve month EBITDA, less Non-Financed Capital Expenditures (other than capital expenditures financed by means of an advance under the credit facility), cash taxes and all Restricted Junior Payments consisting of certain Pass-Through Tax Liabilities, divided by (ii) the sum of our cash interest (other than interest paid-in-kind, amortization of financing fees, and other non-cash interest expense) and principal debt payments (other than repayment of principal on advances under the credit facility and including cash payments with respect to capital leases), any management, consulting, monitoring, and advisory fees paid to an affiliate, and all Restricted Junior Payments (other than Pass-Through Tax Liabilities) and other cash distributions; provided, that if any acquisition is consented to by the lender after the date of the Amended Credit Agreement, the components of the Fixed Charge Coverage Ratio will be calculated for such fiscal period after giving pro forma effect to the acquisition assuming that such transaction has occurred on the first day of such period (including pro forma adjustments arising out of events which are directly attributable to such acquisition, are factually supportable, and are expected to have a continuing impact, in each case to be reasonably agreed to by the lender).

If in the future our Liquidity falls below $20,000 (or Excess Availability falls below 50% of our minimum Liquidity), our Fixed Charge Coverage Ratio is less than 1.1:1.0, or if we otherwise fail to perform or otherwise comply with certain of our covenants or other agreements under the Amended Credit Agreement, it would result in an event of default under the Amended Credit Agreement, which could result in any indebtedness we may take on becoming immediately due and payable.
