9. Debt and Borrowing Arrangements

On December 21, 2011, the Company entered into a five-year syndicated credit agreement (the “Credit Agreement”) with a facility of $175.0 million (the “Facility”). The entire Facility is available for revolving loans and the issuance of letters of credit. The Company has an option to increase the commitments under the Facility or enter into incremental term loans, subject to certain conditions, by up to an additional $75.0 million upon receipt of additional commitments from new or existing lenders. Up to $25.0 million of the Facility is available for swingline loans.

Revolving loans under the Credit Agreement bear interest, at the Company’s option, at either (1) the ABR, which is the greatest of the Prime Rate, the Federal Funds Effective Rate plus 0.50% or LIBOR plus 1.00%, plus in each case an applicable margin ranging from 0.00% to 1.00%; or (2) LIBOR plus an applicable margin ranging from 1.00% to 2.00%. The applicable margin is determined based on the Company’s leverage ratio (the “Leverage Ratio”), defined under the Credit Agreement as consolidated total indebtedness divided by consolidated EBITDA as defined by the Credit Agreement (“Consolidated EBITDA”). Letters of credit issued under the Facility are subject to a letter of credit fee of 1.00% to 2.00%, based on the Company’s leverage ratio and a facing fee of 0.125%. Swingline loans bear interest at the ABR rate. The Company is currently required to pay a 0.2% commitment fee on the unused portion of the Facility.

Subject to certain exceptions, the Facility is secured by substantially all of the United States assets of the Company and its subsidiaries and by a pledge of all of the capital stock of the Company’s subsidiaries. The Company’s subsidiaries also guarantee the repayment of all amounts due under the Credit Agreement. The Credit Agreement provides for customary events of default. If an event of default occurs and is continuing, on the terms and subject to the conditions set forth in the Credit Agreement, amounts outstanding under the Facility may be accelerated and may become or be declared immediately due and payable.

Under the Credit Agreement, the Company is subject to certain financial covenants and must maintain a maximum Leverage Ratio of 3.0 and a minimum interest coverage ratio of 3.0, (“Interest Coverage Ratio”), defined under the Credit Agreement as Consolidated EBITDA divided by interest expense. The Company was in compliance with the financial covenants at December 31, 2015, as well as in all previous quarters. The Credit Agreement also contains a number of covenants including limitations on asset sales, investments, indebtedness and liens.

The Company had no revolving loans outstanding as of December 31, 2015 and 2014. As of December 31, 2015 and 2014, the Company had approximately $19.3 million in irrevocable standby letters of credit outstanding at an interest rate of 1.125%. The Company had $155.7 million available for borrowing under the Facility as of December 31, 2015.
