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:

Pursuant to that certain Agreement and Plan of Merger, dated December 10, 2014 (the “Merger Agreement”), by and between DB Servicing Corporation and Discover Products Inc., DB Servicing Corporation (“DBSC”) merged into Discover Products Inc. (“DPI”), with DPI being the surviving entity (the “Merger”). The Merger was effective as of 11:59 p.m. EST on December 31, 2014. As a result of the Merger, as of January 1, 2015, all the servicing functions described in the Prospectus dated October 8, 2014 (the “Prospectus”) as being performed by DBSC will be performed by DPI, as subservicer of Discover Bank, in addition to the duties already performed by DPI.

To reflect the additional duties of DPI, Discover Bank and DPI entered into the Third Amended and Restated Services Addendum, a copy of which is filed with this Form 8-K as Exhibit 99.1. DPI is a Utah corporation and is a direct subsidiary of Discover Bank. Pursuant to the Merger Agreement, DPI will also assume all rights and obligations of DBSC under all agreements to which DBSC was a party prior to the Merger.

Because DPI is acquiring all of the assets, properties, rights and obligations of DBSC under the Merger Agreement, the servicing policies and procedures used to service the receivables owned by Discover Card Master Trust I (the “Master Trust”) have not changed from those described in the Prospectus. As compensation for providing services to Discover Bank as described in the Prospectus, DPI receives a monthly servicing fee and is reimbursed for certain of its expenses. However, these payments are solely the obligation of Discover Bank and are not payable from assets of the Master Trust or by Discover Card Execution Note Trust (the “Note Trust”). Discover Bank, as master servicer, is ultimately responsible for the overall servicing function for the Master Trust and the Note Trust.
