4. Borrowings

The Company has a $425 million credit agreement maturing November 2016. The credit agreement consists of a $425 million revolving credit facility, including a $375 million sub-limit for letters of credit. The Company has the ability to increase the facility by $100 million under certain circumstances. Borrowings under this facility bear interest at the London Interbank Offered Rate (LIBOR) plus a margin of 1.5% as of March 31, 2013. This margin is determined by the Company’s consolidated leverage ratio and may range from 1.5% to 2.0%. Letters of credit reduce the amount available to borrow by their face value. The unused portion of the facility bears a commitment fee of 0.25%. The Company’s borrowings under the credit agreement are guaranteed by the Company’s U.S. based subsidiaries and are secured by substantially all of the Company’s and certain subsidiaries’ assets. The agreement contains various representations, warranties, affirmative, negative and financial covenants, and conditions of default customary for financing agreements of this type. As of March 31, 2013, $55 million was outstanding under the revolving credit facility and letters-of-credit outstanding totaled $185.6 million.

Several of the Company’s foreign subsidiaries maintain bank lines-of-credit, denominated in local currencies, to meet short-term working capital requirements and for the issuance of letters-of-credit. As of March 31, 2013, $6.3 million was outstanding under these letter-of-credit facilities, while no debt was outstanding. As of March 31, 2013, the total amount available under these credit facilities was $35.6 million, with a total cash borrowing sub-limit of $4.1 million.

In September 2012, the Company entered into a term loan agreement for $11.1 million to fund the acquisition of land and a building in the state of Washington. The loan is payable over seven years and bears interest at LIBOR plus 1.25%, which is payable on a monthly basis. Concurrent with entering into the floating rate loan, the Company entered into an interest rate swap agreement that effectively locks the interest rate of the loan to 2.2% per annum for the term of the loan. As of March 31, 2013, $10.4 million remained outstanding under this loan.
