Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions:

On November 23, 2015, Marriott Vacations Worldwide Corporation (the “Company”) and certain of its subsidiaries entered into Omnibus Amendment No. 3 (the “Amendment”) to certain of the agreements associated with the $250 million warehouse credit facility that the Company and certain of its subsidiaries amended and restated in September 2014 (as amended by the Amendment, the “Warehouse Credit Facility”), including, among others: (1) the Third Amended and Restated Indenture and Servicing Agreement, dated as of September 1, 2014 (the “Indenture”), by and among Marriott Vacations Worldwide Owner Trust 2011-1 (the “Trust”), Marriott Ownership Resorts, Inc. (“MORI”), and Wells Fargo Bank, National Association (“Wells Fargo”); (2) the Second Amended and Restated Sale Agreement, dated as of September 1, 2014 (the “Sale Agreement”), by and between the MORI SPC Series Corp. and the Trust; and (3) the Third Amended and Restated Standard Definitions attached or incorporated into certain of the agreements associated with the Warehouse Credit Facility (the “Standard Definitions”).

The Warehouse Credit Facility allows for the securitization of vacation ownership notes receivable on a non-recourse basis. Pursuant to the Sale Agreement, from time to time, MORI SPC will sell to the Trust vacation ownership notes receivable that it purchases from MORI. Pursuant to the Indenture, the Trust will pledge such vacation ownership notes receivable to the Trustee to secure notes issued by the Trust. The advance rate for vacation ownership notes receivable securitized using the Warehouse Credit Facility varies based on the characteristics of the securitized vacation ownership notes receivable. As a result of the Amendment, the revolving period for the Warehouse Credit Facility has been extended to November 22, 2017. In addition, borrowings under the Warehouse Credit Facility will bear interest at a rate based on the one-month LIBOR and bank conduit commercial paper rates plus 1.15 percent per annum and are generally limited at any point to the sum of the products of the applicable advance rates and the eligible notes receivable at such time. The Company will also owe unused facility and other fees under the Warehouse Credit Facility. The advance rate for vacation ownership notes receivable securitized using the Warehouse Credit Facility will vary based on the characteristics of the securitized vacation ownership notes receivable.

The Amendment also expands the eligibility for certain collateral by permitting some notes receivable with respect to which payments no more than 60 days delinquent to be financed through the Warehouse Credit Facility; prior to the amendment, only delinquent notes that were no more than 30 days delinquent could be financed. Other terms of the Warehouse Credit Facility are substantially similar to those in effect prior to the execution of the Amendment.

Wells Fargo also serves as the trustee and, in some cases, the back-up servicer with respect to certain other transactions involving the securitization of vacation ownership notes receivable undertaken by the Company’s subsidiaries. In addition, from time to time, the financial institutions that provide funding to the Company pursuant to the Warehouse Credit Facility or their affiliates have performed, and may in the future perform, various commercial banking, investment banking and other financial advisory services for the Company and its affiliates for which they have received, and will receive, customary fees and expenses. In particular, these financial institutions or their affiliates are party to the Company’s revolving corporate credit facility and may also have participated in transactions involving the securitization of vacation ownership notes receivable undertaken by the Company’s subsidiaries.
