6. Credit facilities

On January 25, 2008, the Company entered into a Revolving Credit Agreement providing for a senior secured revolving credit facility, with SunTrust Bank as administrative agent, issuing bank and swingline lender (the “Credit Facility”). The Credit Facility provides for a $35.0 million revolving line of credit commitment, which may be used (i) for revolving loans, (ii) for swingline loans, subject to a sublimit of $5.0 million, and (iii) to request the issuance of letters of credit on the Company’s behalf, subject to a sublimit of $25.0 million. The credit available under the Credit Facility may be used, among other purposes, to repurchase shares of the Company’s capital stock and to finance the ongoing working capital, capital expenditure and general corporate needs of the Company.

At December 31, 2012, the Credit Facility had issued five letters of credit totaling $15.5 million on behalf of the Company. Three letters of credit totaling $15.2 million may be called by customers in the event that the Company defaults under the terms of a contract, the probability of which we believe is remote. Two letters of credit totaling $0.3 million have been issued in relation to the Company’s insurance policies. These letters of credit are typically held over the life of the arrangement to which they related. At December 31, 2012, the Company has capacity to borrow, subject to covenant constraints, of up to $19.5 million under this agreement. In addition, two letters of credit for $3.0 million have been issued on behalf of the Company by another financial institution.

The Credit Facility matures on February 28, 2013, at which time all outstanding borrowings must be repaid and all outstanding letters of credit must be terminated or cash collateralized.

The Company’s obligations under the Credit Facility are guaranteed by certain of the Company’s direct and indirect subsidiaries (collectively, the “Guarantors”) and are secured by substantially all of MAXIMUS’ and the Guarantors’ present and future tangible and intangible assets, including the capital stock of subsidiaries and other investment property.

In addition to this credit facility, the Company has a loan agreement with the Atlantic Innovation Fund of Canada. This provides for a loan of up to 1.8 million Canadian Dollars, which must be used for specific technology-based research and development. The loan has no interest charge. This balance is repayable in 38 remaining quarterly installments. At December 31, 2012, $1.7 million (1.7 million Canadian Dollars) were outstanding under this agreement.

Certain contracts require us to provide a surety bond as a guarantee of performance. At December 31, 2012 and September 30, 2011, the Company had performance bond commitments totaling $50.4 million and $48.0 million, respectively. These bonds are typically renewed annually and remain in place until the contractual obligations have been satisfied. Although the triggering events vary from contract to contract, in general, we would only be liable for the amount of these guarantees in the event of default in our performance of our obligations under each contract, the probability of which we believe is remote.
