Item 1.01. Entry into a Material Definitive Agreement

On September 28, 2016, the Corporation and its wholly-owned subsidiary, Martin Marietta Funding LLC (“MM Funding”), entered into the Seventh Amendment to its Credit and Security Agreement with SunTrust Bank dated as of April 19, 2013.  The Credit and Security Agreement was extended and, as amended, is scheduled to terminate on September 27, 2017.  In 2014, SunTrust Bank sold and assigned an interest in its rights and obligations under the Credit and Security Agreement to Regions Bank and PNC Bank, National Association.  Effective with the Seventh Amendment to the Credit and Security Agreement, the facility limit was increased to $300,000,000 and the lenders sold and assigned an interest in their rights and obligations under the Credit and Security Agreement to The Bank of Tokyo-Mitsubishi UFJ, LTD., New York Branch.  The Credit and Security Agreement may be further extended by agreement of the Corporation, MM Funding, SunTrust Bank, and other lenders.  

The Credit and Security Agreement is a $300,000,000 trade receivables securitization facility backed by trade receivables originated by the Corporation or by certain of its subsidiaries and acquired by the Corporation, which the Corporation then sells or contributes to MM Funding.  MM Funding’s borrowings bear interest at one-month LIBOR plus 0.70%, subject to change in the event that this rate no longer reflects the lender’s cost of lending.

The Credit and Security Agreement includes cross-default provisions related to the Corporation’s $350,000,000 revolving credit agreement and $250,000,000 term loan.  

The Seventh Amendment to Credit and Security Agreement is filed as an exhibit hereto and is incorporated herein by reference, and the description of the Seventh Amendment to the Credit and Security Agreement contained herein is qualified in its entirety by the terms of this agreement.
