Item 1.01. Entry into a Material Definitive Agreement.

Arkansas Best Corporation and its subsidiaries (the “Company”) is self-insured up to certain limits for workers’ compensation claims with amounts in excess of such self-insured limits fully insured to levels which management considers appropriate for the Company’s operations. In order to meet regulatory requirements in various states associated with this self-insurance program and to comply with terms of agreements with insurers, the Company is required to post letters of credit to secure these obligations. As of December 11, 2009, the total face amount of all such letters of credit approximated $50 million. Prior to December 11, 2009 the Company arranged for the letters of credit as a part of the existing credit facility under the Second Amended and Restated Credit Agreement as amended on May 4, 2007 (the “Credit Facility”).

On December 11, 2009, the Company entered into:

• a Letter of Credit Agreement with PNC Bank, N.A. to establish a letter of credit facility not to exceed $35 million; and

• a Letter of Credit Agreement with SunTrust Bank to establish a letter of credit facility not to exceed $15 million.

As of December 11, 2009, the Company had in place the following two additional letter of credit arrangements:

• a letter of credit facility with Bank of Tokyo-Mitsubishi UFJ, Ltd. in an amount not to exceed $25 million; and

• an arrangement with U.S. Bank National Association for the discretionary issuance of additional letters of credit upon application by the Company.

Under these arrangements, the Company has up to $90 million of availability for the issuance of letters of credit of which $75 million is committed subject to compliance by the Company with the requirements of issuance.

The Company will substitute letters of credit issued under these new arrangements for the letters of credit previously issued under the Credit Facility. Following the substitution, the existing letters of credit will be cancelled by the issuers. The letters of credit issued under the new arrangements will be secured by the Company’s pledge of cash or other financial assets in an amount not less than the total of such letters of credit. The new letter of credit arrangements contain no financial ratios or financial covenants which the Company will be required to maintain.

The Company is continuing to evaluate its financing arrangements with a view toward increasing the total credit available to the Company.
