Item 1.01 Entry into a Material Definitive Agreement.

The information required by Item 1.01 is included in Item 2.03 and is incorporated by reference herein.

Item 2.03 Creation of a Direct Financial Obligation or an Obligation under an Off Balance Sheet Arrangement of a Registrant.

On February 1, 2015, ArcBest Corporation (the “Company”), through its wholly-owned subsidiary ArcBest Funding LLC (formerly a wholly-owned subsidiary of ABF Freight System, Inc. known as ABF Freight Funding LLC) (the “Borrower”), amended its existing revolving accounts receivable securitization facility with PNC Bank, National Association (“PNC”) by entering into an Amended and Restated Receivables Loan Agreement, dated as of February 1, 2015 and extending through January 2, 2018 (the “Receivables Loan Agreement”) by and among the Company, as initial servicer, the Borrower, as borrower, and PNC, as lender (the “Lender”), letter of credit issuer (“LC Issuer”), and agent and administrator for the Lender and its assigns and the LC Issuer and its assigns (“Agent”).

The Receivables Loan Agreement and related agreements have been amended to, among other things (i) replace the prior servicer, ABF Freight System, Inc., a wholly-owned direct subsidiary, with the Company, (ii) increase the maximum committed funding amount to $100 million, with an accordion feature providing up to an additional $25 million in committed funding amounts, (iii) to increase the number of affiliates of the Company that may sell receivables to the Borrower for financing under the facility, (iv) modify limitations regarding the concentration of certain obligors of receivables pledged under the facility and (v) modify certain calculations used to determine availability under the facility. Borrowings under the facility are secured primarily by a lien on and security interest in the Borrower’s related accounts receivable.  Borrowing advances have no scheduled maturity date, and are payable upon termination of the Receivables Loan Agreement. Advances bear interest based upon LIBOR, plus a margin as specified in the related fee letter. The Borrower pays fees to the Agent, for the account of the Lender, based on the aggregate principal amount of the accounts pledged to the Agent, for the benefit of the Lender, under the Receivables Loan Agreement.

The Receivables Loan Agreement contains representations and warranties, affirmative and negative covenants and events of default that are customary for financings of this type.  As of the date hereof, there have been no borrowings under the facility.

The Receivables Loan Agreement includes a provision under which the Borrower may request, and the LC Issuer may issue, standby letters of credit, primarily in support of workers’ compensation and third-party casualty claims liabilities in various states in which certain subsidiaries of the Company are self-insured. Outstanding standby letters of credit reduce the availability of borrowings under the facility. As of the date hereof, approximately $20.1 million of standby letters of credit have been issued under the facility which reduced the available borrowing capacity to approximately $79.9 million.

Affiliates of PNC have provided from time to time, and may provide in the future, investment and commercial banking and financial advisory services to the Company and its affiliates in the ordinary course of business, for which they have received, and may continue to receive, customary fees and commissions.

The foregoing description of the transactions contemplated by the Receivables Loan Agreement is qualified in its entirety by reference to the Receivables Loan Agreement, a copy of which is filed as
