On September 24, 2013, Marriott International, Inc. (“we”) entered into a Terms Agreement with Deutsche Bank Securities Inc., Goldman, Sachs & Co., and the other Underwriters listed on Schedule I thereto (the “Terms Agreement,” which incorporates by reference the Underwriting Agreement General Terms and Provisions, dated June 9, 2006 (the “Underwriting Agreement”) (which we previously filed on June 14, 2006 as Exhibit 1.1 to our Current Report on Form 8-K)) to issue $350 million aggregate principal amount of our 3.375% Series M Notes due 2020 (the “Notes”). We received net proceeds of approximately $345.0 million from the offering of the Notes, after deducting the underwriting discount and estimated expenses of the offering. We expect to use these proceeds for general corporate purposes, which may include working capital, capital expenditures, acquisitions, stock repurchases or repayment of commercial paper borrowings as they become due.

We will pay interest on the Notes on April 15 and October 15 of each year, commencing on April 15, 2014. The Notes will mature on October 15, 2020, and we may redeem them, in whole or in part, at our option, under the terms provided in the form of Note.

We issued the Notes under an indenture dated as of November 16, 1998 with The Bank of New York Mellon, as successor to JPMorgan Chase Bank, N.A., formerly known as The Chase Manhattan Bank, as trustee (the “Indenture”) (which we previously filed as Exhibit 4.1 to our Annual Report on Form 10-K for the fiscal year ended January 1, 1999).

In connection with the public offering of the Notes, we filed a Prospectus dated February 16, 2012 and a Prospectus Supplement dated September 24, 2013 with the Securities and Exchange Commission, each of which forms a part of our Registration Statement on Form S-3 (Registration No. 333-179554) (the “Registration Statement”). We are filing the Terms Agreement, the Indenture Officer’s Certificate pursuant to Section 301 of the Indenture, the form of Note, and a legal opinion of our counsel, Gibson, Dunn & Crutcher LLP, on the Notes as exhibits to this report for the purpose of incorporating them as exhibits to the Registration Statement.
