In February 2012, we entered into a three year agreement (the “Credit Facility”) for a $20,000,000 revolving line of credit (“Line of Credit”) and up to $1,000,000 of letters of credit, maturing in February 2015. Funds from the Credit Facility may be used for general working capital and corporate needs, retiring existing debt, or to support acquisitions and capital expenditures.

Under the Credit Facility, indebtedness bears interest at either: (1) LIBOR, as defined, plus an applicable margin ranging from 1.25% to 2.00%; or (2) the bank’s commercial bank floating rate (“CBFR”), which is the greater of the bank’s prime rate or one month LIBOR + 2.50%, adjusted down, from 1.25% to 0.50%. We elect the interest rate with each borrowing under the line of credit. In addition, there is an unused capacity fee of 0.15% to 0.30%. The adjustments and unused capacity fee depend on the ratio of funded debt to our trailing four quarters of EBITDA, as defined, with four tiers ranging from a ratio of less than one to greater than two. Letter of credit fees are based on the applicable LIBOR rate.

The Credit Facility is secured by all of our assets and requires us to maintain a ratio of funded debt to our trailing four quarters of EBIDTA, as defined, of 2.5 to 1.0, and a minimum fixed charge coverage ratio of 1.5 to 1.0. We were in compliance with these covenants at March 31, 2013.

In order to facilitate the Bios Acquisition, in May 2012 we borrowed $11,000,000 under the terms of the Line of Credit. During the year ended March 31, 2013 we made principal repayments of $7,000,000. As a result, the amount outstanding under the Line of Credit was $4,000,000 as of March 31, 2013. In April 2013, we made an additional principal payment of $1,000,000.

Future contractual maturities of debt are as follows (in thousands):

In April 2010, we entered into a credit facility consisting of: a) 36 month reducing line of credit for $3,000,000 and maturing at April 27, 2013, requiring quarterly principal payments of $250,000 beginning July 27, 2010, which was retired in February 2012; and b) revolving line of credit for $4,000,000 maturing on December 23, 2011, which was retired in December 2011. Both of these lines of credit were subject to a variable rate of interest and a rate floor.
