4. Borrowings

The Company has a $450 million credit agreement maturing in May 2019. The credit agreement consists of a $450 million revolving credit facility, including a $375 million sub-limit for letters of credit. The Company has the ability to increase the facility by $200 million under certain circumstances. Borrowings under this facility bear interest at the London Interbank Offered Rate (“LIBOR”) plus a margin of 1.25% as of September 30, 2014. This margin is determined by the Company’s consolidated leverage ratio and may range from 1.25% to 2.0%. Letters of credit reduce the amount available to borrow by their face value. As of September 30, 2014, the unused portion of the facility bears a commitment fee of 0.20%, but can range from 0.20% to 0.35% based on the Company’s consolidated leverage ratio. 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 September 30, 2014, there was $30.0 million outstanding under the revolving credit facility and $100.1 million outstanding under the letters-of-credit sub-facility.

Several of the Company’s foreign subsidiaries maintain bank lines-of- credit, denominated in local currencies and US dollars, to meet short-term working capital requirements and for the issuance of letters-of-credit. As of September 30, 2014, $11.6 million was outstanding under these letter-of-credit facilities, while no debt was outstanding. As of September 30, 2014, the total amount available under these credit facilities was $26.4 million, with a total cash borrowing sub-limit of $2.9 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, which bears interest at LIBOR plus 1.25%, is payable on a monthly basis over seven years. 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.
