[1] | We have the option to elect if the borrowings will bear interest at either, a base rate plus the base rate margin or a Eurodollar rate, for the applicable period, plus the Eurodollar margin at the time of the borrowing. The applicable margin varies based upon a certain leverage ratio, as defined by the Revolving Credit Facility. Letters of credit outstanding under the Revolving Credit Facility incur fees at the Eurodollar margin rate.
