Senior Secured Term Loan and Revolving Credit Facility

The senior secured term loan (the “Term Loan Facility”) is under a credit agreement that includes a five-year senior secured revolving credit facility allowing borrowings of up to $250 million, with a letter of credit sub-facility in an amount of $75 million and a swingline sub-facility in an amount of $25 million (the “Revolving Credit Facility”, and together with the Term Loan Facility, the “Senior Credit Facilities”). The Senior Credit Facilities are secured by substantially all of our assets located in the United States and a certain percentage of our foreign subsidiaries’ capital stock.

Borrowings under the Term Loan Facility bear interest, at our option, at either (i) a reserve-adjusted LIBOR rate, subject to a floor of 0.75%, plus 3.25%, or (ii) a base rate, subject to a floor of 0.75%, (calculated as the greatest of (1) the prime rate, (2) the U.S. federal funds effective rate plus 0.50% or (3) the one month LIBOR rate plus 1.00%) plus 2.25%. As of September 30, 2016, the interest rate in effect for the Term Loan Facility was 4.00%.

Borrowings under the Revolving Credit Facility bear interest, at our option, at either (i) a reserve-adjusted LIBOR rate, plus a margin ranging between 1.75% to 2.50% per annum, depending on our consolidated total leverage ratio, or (ii) the base rate plus a margin ranging between 0.75% to 1.50% per annum, depending on our consolidated total leverage ratio. The unused portion of the Revolving Credit Facility is subject to a commitment fee equal to (i) 0.25% per annum, when our consolidated total leverage ratio is less than 2.25 to 1.00 or (ii) 0.40% per annum, otherwise. As of September 30, 2016, we had $10 million of borrowings and letters of credit of $4 million outstanding under the Revolving Credit Facility, leaving $236 million available for borrowing.

On May 2, 2016, we borrowed $72 million under our Revolving Credit Facility to partially fund our acquisition of Medsystems. See Note 2, “Business Acquisition” for a description of this acquisition. By September 30, 2016, we had repaid $62 million of the borrowings on our Revolving Credit Facility. As of September 30, 2016, the interest rate in effect for the Revolving Credit Facility was 2.77%.
