8. LINE OF CREDIT

The Company has a credit agreement with Whitney Bank and JPMorgan Chase Bank, N.A. that provides the Company with an $80 million revolving credit facility (the “Credit Facility”). The Credit Facility also allows the Company to use up to the full amount of the available borrowing base for letters of credit. On October 23, 2014, we entered into an amendment to our credit facility to extend the maturity date from December 31, 2014 to December 31, 2015.

The Credit Facility is secured by substantially all of our assets other than real property located in the state of Louisiana. Amounts borrowed under the Credit Facility bear interest, at our option, at either the prime lending rate established by JPMorgan Chase Bank, N.A. or LIBOR plus 1.5 percent. We pay a fee on a quarterly basis of one-fourth of one percent per annum on the weighted-average unused portion of the Credit Facility.

At December 31, 2014, no amounts were outstanding under the Credit Facility, and we had outstanding letters of credit totaling $21.0 million, reducing the unused portion of our credit facility to $59.0 million. We are required to maintain certain financial covenants, including a minimum current ratio of 1.25 to 1.0, a net worth minimum requirement of $254.1 million, debt to net worth ratio of 0.5 to 1.0, and earnings before interest, taxes, depreciation and amortization (EBITDA) to interest expense ratio of 4.0 to 1.0. As of December 31, 2014, we were in compliance with these covenants.
