Credit Facility, interest rate description |  |  | At our option, outstanding principal amounts on the Credit Facility bear interest at a variable rate equal to either (i) the London Interbank Offered Rate (LIBOR) plus an agreed margin (ranging from 100 to 225 basis points), which is to be established quarterly based on the Company’s ratio of consolidated EBITDA, defined as earnings before interest, taxes, depreciation, and amortization, to the Company’s consolidated indebtedness (the Leverage Ratio); or (ii) an alternative base rate which is the higher of (a) the prime rate or (b) the federal funds rate plus 1⁄2% per annum plus an applicable rate (ranging from 0 to 125 basis points). In the case of loans bearing interest at a rate based on the federal funds rate, interest payments are payable quarterly. In the case of loans bearing interest at a rate based on LIBOR, interest is payable at the end of the LIBOR advance periods, which can be up to nine months at the option of the Company. The Company is also required to pay a commitment fee on unused available borrowings under the Credit Facility ranging from 10 to 35 basis points depending upon the Leverage Ratio. |  |
