On June 28, 2013, the Company also entered into the Third Amendment to the Amended and Restated Master Shelf Agreement with its long term note holders (as amended, the Restated Master Shelf Agreement) that made changes to this agreement to conform with certain changes in the Restated Credit Agreement.

Restated Credit Agreement

The Restated Credit Agreement is a revolving credit facility for up to $200 million expiring in June 2018. The Restated Credit Agreement also has an accordion feature that allows for an additional $40 million availability, subject to lender approval. The Restated Credit Agreement provides for a LIBOR rate margin range from 125 basis points to 250 basis points, base rate margins from minus 12.5 to plus 50 basis points, letter of credit fee range from 137.5 basis points to 262.5 basis points and an unused portion fee from 20 basis points to 32.5 basis points in each case based on the Company’s leverage ratio.

Under the Restated Credit Agreement, the Company must maintain certain financial covenants including a minimum fixed charge coverage ratio, a maximum leverage ratio and a minimum tangible net worth, among others. The Restated Credit Agreement also provides for a pledge by the Company of certain land and structures, certain tractors, trailers and other personal property and accounts receivable, as defined in the Restated Credit Agreement. Total bank commitments under the Restated Credit Agreement are $200 million. If the Company’s leverage ratio exceeds a 3-to-1 ratio, the bank commitments become subject to a borrowing base calculated utilizing certain pledged property, equipment and accounts receivable as defined in the Restated Credit Agreement.

At March 31, 2014, the Company had borrowings of $51.1 million and outstanding letters of credit of $45.1 million under the Restated Credit Agreement. At March 31, 2013, the Company had borrowings of $8.0 million and outstanding letters of credit of $59.1 million under the Restated Credit Agreement. The available portion of the Restated Credit Agreement may be used for general corporate purposes, including future capital expenditures, working capital and letter of credit requirements as needed.

Restated Master Shelf Agreement

On September 20, 2002, the Company issued $100 million in Senior Notes under a $125 million (amended to $150 million in April 2005) Master Shelf Agreement with Prudential Investment Management, Inc. and certain of its affiliates. The Company issued another $25 million in Senior Notes on November 30, 2007 and $25 million in Senior Notes on January 31, 2008 under the same Master Shelf Agreement.

The initial $100 million Senior Notes have a fixed interest rate of 7.38 percent. Payments due under the $100 million Senior Notes were interest only until June 30, 2006 and at that time semi-annual principal payments began with the final payment due December 2013. The November 2007 issuance of $25 million Senior Notes has a fixed interest rate of 6.14 percent. The January 2008 issuance of $25 million Senior Notes has a fixed interest rate of 6.17 percent. Payments due for both $25 million issuances were interest only until June 30, 2011 and at that time semi-annual principal payments began with the final payments due January 1, 2018.
