Item 8.01. Other Events.

On December 8, 2006, the Board of Directors of Genworth Financial, Inc. (the “Company”) approved a stock repurchase program, authorizing the Company to repurchase up to $500 million of its common stock over the 12-month period commencing January 1, 2007. The Company expects the purchases to be made from time to time in the open market, through block trades or otherwise (including, without limitation, using so-called Rule 10b5-1 plans), or in privately negotiated transactions.

The timing of the share repurchases under the program will depend on a variety of factors, including market conditions, and may be suspended or discontinued at any time. Common stock acquired through the repurchase program will be held as treasury shares and may be used for general corporate purposes, including reissuances in connection with acquisitions, employee stock option exercises or other employee stock plans.

This report includes certain “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. These forward-looking statements include, but are not limited to the Company’s plans, objectives, expectations and intentions and other statements contained in this report that are not historical facts as well as statements identified by words such as “expects”, “will”, or words of similar meaning. These statements are based on the Company’s current beliefs or expectations and are inherently subject to significant uncertainties and changes in circumstances, many of which are beyond the Company’s control. Actual results may differ materially from these expectations due to changes in global political, economic, business, competitive, market and regulatory factors.
