The applicable margin ranges from 1.00% to 1.75% for base rate loans and from 2.00% to 2.75% for LIBOR loans, in each case depending on the amount of the loan outstanding in relation to the borrowing base.

In addition, the Company is required to maintain certain financial ratios, including a minimum modified current ratio which includes the available borrowing base of 1.0 to 1.0 and a maximum annualized quarterly leverage ratio of 4.0 to 1.0. The Company is also required to submit an audited annual report 120 days after the end of each fiscal period. As of March 31, 2016 and December 31, 2015, the Company was in compliance with these covenants under the credit facility. Interest expense for the three months ended March 31, 2016 and 2015, includes amortization of deferred financing costs of $70,000 and $65,000, respectively. As of March 31, 2016 and December 31, 2015, $0.8 million of costs, net of amortization, associated with the credit facility have been capitalized.
