Affinion Group, Inc. (“Affinion”) is participating in the Credit Suisse Global Credit Products Conference (the “Conference”) to be held on Thursday, October 4, 2012 in Miami, Florida, at which Todd Siegel, Affinion’s Chief Executive Officer, is scheduled to deliver a presentation. As part of such presentation, Affinion intends to disclose certain information pertaining to the contribution of large financial institutions to its business results. Specifically, the contribution of the top 10 domestic financial institutions, as ranked by SNL Financial according to total assets as of June 30, 2012, to Affinion’s Membership business (excluding other lines of business, such as International) is estimated to have been approximately 28% of Affinion’s total net revenues of $1.54 billion for the twelve months ended June 30, 2012, and reflects the contributions of millions of consumers that have been acquired through more than 30 years of previous marketing efforts, and for which Affinion typically enjoys an ongoing billing relationship until such time as the individual consumer cancels the service.

Affinion does not regularly report the preceding information, and does not expect to begin doing so after this presentation.

At the Conference, Affinion is also expected to re-affirm its guidance that 2012 Adjusted EBITDA will decline at a mid-to-high single digit rate as compared to the $366.4 million of Adjusted EBITDA achieved in 2011.

Note: The information contained in this Current Report shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended, or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, except as expressly set forth by specific reference in such a filing.
