Debt Disclosure [Abstract] |
Revolving Credit Facility | Revolving Credit Facility Our revolving credit facility provides for maximum borrowings of $30.0 million which is provided by BOKF, NA dba Bank of Oklahoma, formerly known as Bank of Oklahoma, N.A. ("Bank of Oklahoma"). Under the line of credit, there was one standby letter of credit totaling $0.8 million as of December 31, 2015. Borrowings available under the revolving credit facility at December 31, 2015, were $29.2 million. Interest on borrowings is payable monthly at LIBOR plus 2.5%. No fees are associated with the unused portion of the committed amount. As of December 31, 2015 and 2014, we had no balance outstanding under our revolving credit facility. At December 31, 2015 and 2014, the weighted average interest rate was 2.6% and 2.7%, respectively. At December 31, 2015, we were in compliance with our financial covenants. These covenants require that we meet certain parameters related to our tangible net worth, total liabilities to tangible net worth ratio and working capital. At December 31, 2015 our tangible net worth was $178.9 million, which meets the requirement of being at or above $95.0 million. Our total liabilities to tangible net worth ratio was 0.3 to 1.0, which meets the requirement of not being above 2 to 1. Our working capital was $80.8 million which meets the requirement of being at or above $40.0 million. Effective July 25, 2014, the Company amended its revolving credit facility with the Bank of Oklahoma. The amendment extends the termination date of the revolving credit facility to July 27, 2016.
