Line of Credit, Long-Term Debt [Abstract] |
Long-Term Debt | Long-Term Debt In November 2013, we entered into a Credit Agreement with Wells Fargo Bank, National Association, (the “Bank”). Pursuant to the Credit Agreement, the Bank provided a five-year, $250.0 million unsecured revolving line of credit which may be used for future working capital, equipment financing, and general corporate purposes. The Bank's commitment decreased to $175.0 million on November 1, 2016 through October 31, 2018. The Credit Agreement is unsecured, with a negative pledge against all assets of our consolidated group, except for debt associated with permitted acquisitions, new purchase-money debt and capital lease obligations as described in the Credit Agreement. The Credit Agreement matures on October 31, 2018. The Borrower has the ability to terminate the commitment at any time at no additional cost to the Borrower. Borrowings under the Credit Agreement can either be, at Borrower's election, (i) one-month or three-month LIBOR (Index) plus 0.625%, floating, or (ii) Prime (Index) plus 0.0%, floating. There is a commitment fee on the unused portion of the Revolver at 0.0625%, due monthly. The Credit Agreement contains customary financial covenants including, but not limited to, (i) a maximum adjusted leverage ratio of 2:1, measured quarterly on a trailing twelve month basis, (ii) a minimum net income requirement of $1.00, measured quarterly on a trailing twelve month basis, (iii) a minimum tangible net worth of $175.0 million requirement, measured quarterly, and (iv) limitations on other indebtedness and liens. The Credit Agreement also includes customary events of default, conditions, representations and warranties, and indemnification provisions. We were in compliance with the respective financial covenants at September 30, 2017. We had no outstanding long-term debt at September 30, 2017 or December 31, 2016. We assumed $23.3 million of debt related to the IDC acquisition on July 6, 2017, all of which was repaid prior to September 30, 2017. Outstanding letters of credit associated with the revolving line of credit at September 30, 2017 were $3.7 million. As of September 30, 2017, the line of credit available for future borrowing was $171.3 million.
