Long-Term Debt

In November 2013, we entered into a credit agreement (the “Credit Agreement”) by and among Wells Fargo Bank, National Association, (the “Bank”), Heartland Express, Inc. of Iowa as the borrower (the “Borrower”), us, GTI, and the other members of our consolidated group, as Guarantors. Pursuant to the Credit Agreement, the Bank provided a five-year, $250.0 million unsecured revolving line of credit. The line of credit is available for working capital, equipment financing, and general corporate purposes. The Bank's commitment decreased to $225.0 million on November 1, 2014, and will decrease to $200.0 million on November 1, 2015, and to $175.0 million from November 1, 2016 through October 31, 2018.

The Credit Agreement is unsecured, with a negative pledge against all assets of our consolidated group, except for debt associated with permitted acquisitions, new purchase-money debt and capital lease obligations as described in the Credit Agreement. The Credit Agreement matures on October 31, 2018. The Borrower has the ability to terminate the commitment at any time at no additional cost to the Borrower. Borrowings under the Credit Agreement can either be, at Borrower's election, (i) one-month or three-month LIBOR (Index) plus 0.625%, floating, or (ii) Prime (Index) plus 0.0%, floating. There is a commitment fee on the unused portion of the Revolver at 0.0625%, due monthly.

The Credit Agreement contains customary financial covenants including, but not limited to, (i) a maximum adjusted leverage ratio of 2:1, measured quarterly on a trailing twelve month basis, (ii) a minimum net income requirement of $1.00, measured quarterly on a trailing twelve month basis, (iii) a minimum tangible net worth of $200 million requirement, measured quarterly, and (iv) limitations on other indebtedness and liens. The Credit Agreement also includes customary events of default, conditions, representations and warranties, and indemnification provisions. We were in compliance with the respective financial covenants at March 31, 2015.

Long term debt consisted of the following at March 31, 2015 and December 31, 2014 (in thousands):

Outstanding letters of credit associated with the revolving line of credit at March 31, 2015 were $4.4 million. As of March 31, 2015, the line of credit available for future borrowing was $220.6 million.
