Debt Disclosure [Abstract] |
Line of Credit | Line of Credit We have a $50.0 million unsecured revolving line of credit with a domestic bank, of which $10.0 million is available for letters of credit. The credit agreement matures on December 31, 2021 and has an accordion feature which allows for an increase in the total line of credit up to $100.0 million, subject to certain conditions, including the availability of additional bank commitments. At December 31, 2019 and 2018, there were no borrowings under the line. Under the terms of the line of credit, available borrowings are reduced by outstanding letters of credit. As of December 31, 2019, we had letters of credit outstanding of approximately $2.7 million under the facility and available borrowing of $47.3 million. Advances under the line of credit bear interest at LIBOR plus 1.0 to 1.5% per year determined in accordance with a pricing grid based on our funded debt to earnings before interest, taxes, depreciation and amortization ("EBITDA") ratio. We are required to comply with a maximum funded debt to EBITDA ratio of no greater than 2.50 to 1.00 based upon a trailing four fiscal quarter period. At December 31, 2019, our funded debt to EBITDA ratio was 0.0004 to 1.00.
