Item 7.01. Regulation FD Disclosure.
 
On December 10, 2009, MDC Partners Inc. (the “Company”) posted the supplemental financial information attached as Exhibit 99.1 hereto on its web site (www.mdc-partners.com).  This supplemental financial information includes the Company’s quarterly financial data for the first three quarters of 2009 and 2008, reclassified to reflect the changes in its reportable business segments.
 
 As a result of changing client demand and the Company’s focus on driving return on marketing investment, the Company is changing its segment reporting to conform them more closely with how the Chief Operating Decision Maker (“CODM”) and management are building and managing the Company’s business segments.  This will simplify the Company’s financial reporting and make its results more consistent with how the CODM and the Board of Directors view the business.  The Company is focused on expanding its capabilities in database marketing and data analytics in order to position the Company for future business development efforts and revenue growth. 

In order to position this strategic focus along the lines of how the CODM and management will base their business decisions, the Company has now reorganized its segment reporting. Decisions regarding allocation of resources are made and will be made based not only on the individual operating results of the subsidiaries but also on the overall performance of the reportable segments.
 
The foregoing information (including the exhibits hereto) is being furnished under “Item 7.01. Regulation FD Disclosure.”  Such information (including the exhibits hereto) shall not be deemed "filed" for purposes of Section 18 of the Securities Exchange Act of 1934, as amended, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, except as shall be expressly set forth by specific reference in such filing.
