Line of Credit and Capital Lease Obligations: | 10. Line of Credit and Capital Lease Obligations: On November 19, 2012, the Company entered into an amended and restated credit agreement (“Amended and Restated Line of Credit”) which increased the borrowing capacity thereunder to $800 million from $500 million. The Amended and Restated Line of Credit matures on November 17, 2017. The Line of Credit, which is guaranteed by substantially all of the Company’s subsidiaries and affiliated professional contractors, includes (1) a $75 million sub-facility for the issuance of letters of credit and (2) a $37.5 million sub-facility for swingline loans. The Line of Credit may be increased up to $1.0 billion, subject to the satisfaction of specified conditions. At the Company’s option, borrowings under the Line of Credit (other than swingline loans) bear interest at (1) the alternate base rate (defined as the highest of (i) the Wells Fargo Bank, National Association prime rate, (ii) the Federal Funds Rate plus 1/2 of 1.000% and (iii) one month LIBOR plus 1.000%) or (2) the LIBOR rate, as defined in the Line of Credit, plus, an applicable margin rate ranging from 0.125% to 0.750% for alternate base rate borrowings and 1.125% to 1.750% for LIBOR rate borrowings, in each case based on the Company’s consolidated leverage ratio. Swingline loans bear interest at the alternate base rate plus the applicable margin rate. The Company is subject to certain covenants and restrictions specified in the Line of Credit, including covenants that require the Company to maintain a minimum fixed charge coverage ratio and not to exceed a specified consolidated leverage ratio, to comply with laws, and restrict the Company from paying dividends and making certain other distributions, as specified therein. Failure to comply with these covenants would constitute an event of default under the Line of Credit, notwithstanding the Company’s ability to meet its debt service obligations. The Line of Credit includes various customary remedies for the lenders following an event of default. At December 31, 2012, the Company believes it was in compliance, in all material respects, with the financial covenants and other restrictions applicable under the Line of Credit. The Company had $144.0 million in outstanding principal balance under the Line of Credit at December 31, 2012. The Company has outstanding letters of credit associated with its professional liability insurance program which reduced the amount available under the Line of Credit by $5.5 million at December 31, 2012. The weighted average interest rate on the letters of credit was 1.3% at December 31, 2012. At December 31, 2012, the Company had an available balance on the Line of Credit of $650.5 million.
