Credit Agreement
Credit Agreement	10. Credit Agreement As of September 27, 2014, CRA is party to a credit agreement that provides CRA with a $125.0 million revolving credit facility and a $15 million sublimit for the issuance of letters of credit. CRA may use the proceeds of the revolving credit facility for working capital and other general corporate purposes. CRA may repay any borrowings under the revolving credit facility at any time, but no later than April 24, 2018. There was no amount outstanding under this revolving line of credit as of September 27, 2014. As of September 27, 2014, the amount available under this revolving line of credit was reduced by certain letters of credit outstanding, which amounted to $1.3 million. Borrowings under the revolving credit facility bear interest at a rate per annum of either (i) the adjusted base rate, as defined in the credit agreement, plus an applicable margin, which varies between 0.50% and 1.50% depending on CRA's total leverage ratio as determined under the credit agreement, or (ii) the adjusted eurocurrency rate, as defined in the credit agreement, plus an applicable margin, which varies between 1.50% and 2.50% depending on CRA's total leverage ratio. CRA is required to pay a fee on the unused portion of the revolving credit facility at a rate per annum that varies between 0.25% and 0.375% depending on its total leverage ratio. Borrowings under the credit facility are secured by 100% of the stock of certain of CRA's U.S. subsidiaries and 65% of the stock of certain of its foreign subsidiaries, which represent approximately $6.8 million in net assets as of September 27, 2014. Under the credit agreement, CRA must comply with various financial and non-financial covenants. Compliance with these financial covenants is tested on a fiscal quarterly basis. Any indebtedness outstanding under the credit facility may become immediately due and payable upon the occurrence of stated events of default, including CRA's failure to pay principal, interest or fees or a violation of any financial covenant. The financial covenants require CRA to maintain a consolidated interest expense to adjusted consolidated EBITDA ratio of more than 2.5 to 1.0 and to comply with a consolidated debt to adjusted consolidated EBITDA ratio of not more than 3.0 to 1.0. The non-financial covenant restrictions of the senior credit agreement include, but are not limited to, CRA's ability to incur additional indebtedness, engage in acquisitions or dispositions, and enter into business combinations. As of September 27, 2014, CRA was in compliance with the covenants of its credit agreement.
