Debt Disclosure [Abstract]
Debt	Note 7. Debt Line of Credit On November 27, 2017, we entered into a secured credit agreement with Wells Fargo Bank, National Association (as amended or otherwise modified from time to time, the “November 2017 Facility”) and in July 2019, we entered into Amendment No. 1 to the November 2017 Facility. Pursuant to the terms of the amendment, among other changes, (i) the maturity date of borrowings under the November 2017 Facility was extended from November 27, 2020 to July 12, 2022; (ii) the revolving commitments were increased from $85.0 million to $100.0 million; (iii) the sublimit for the issuance of letters of credit was increased from $30.0 million to $45.0 million; and (iv) the covenant in the November 2017 Facility that limits the amount of finance leases and debt that we can incur to finance the acquisition, construction or improvement of any equipment or capital assets was increased from $100.0 million to $200.0 million. The proceeds of the revolving loans may be used for general corporate purposes. The revolving loans accrue interest at a prime rate plus a margin of 0.25% or, at our option, a LIBOR rate (based on one, three or six-month interest periods) plus a margin of 1.00%. Interest on the revolving loans is payable quarterly in arrears with respect to loans based on the prime rate and at the end of an interest period in the case of loans based on the LIBOR rate (or at each three-month interval if the interest period is longer than three months). Borrowings under the November 2017 Facility are collateralized by substantially all of our assets. The November 2017 Facility requires us to comply with a maximum leverage ratio and a minimum liquidity requirement. Additionally, the November 2017 Facility contains customary affirmative and negative covenants, including covenants limiting our, and our subsidiaries’, ability to, among other things, grant liens, incur debt, pay dividends or distributions on the capital stock, effect certain mergers, make investments, dispose of assets and enter into transactions with affiliates, in each case subject to customary exceptions for a credit facility of the size and type of the November 2017 Facility. As of October 31, 2019, the outstanding borrowings under the credit facility were $40.0 million. As of October 31, 2019, we were in compliance with all financial covenants. In connection with the above credit facility, for the three and nine months ended October 31, 2019 and 2018, interest expense, net of capitalized interest costs, was not material. During the same periods, we did not capitalize any interest amounts. Interest expense in connection with the above credit facilities includes interest charges for our line of credit, amortization of issuance costs, and unused commitment fees on our line of credit. Effective September 5, 2019, we entered into a Swap Agreement with Wells Fargo Bank, National Association, in order to minimize our interest rate risk exposure due to the volatility of LIBOR. Under the Swap Agreement, we have hedged a portion of the variable interest payments of our debt by effectively fixing our interest payments over the five year term of the agreement. Refer to Note 3 for further details.
