On November 3, 2011, Genworth Financial, Inc. (the “Company”) furnished its financial supplement for the quarter ended September 30, 2011 on a Current Report on Form 8-K. Beginning in the fourth quarter of 2011, the Company changed its operating business segments to better align its businesses. Under the new structure, the Company operates through three divisions: Insurance and Wealth Management, Mortgage Insurance and Corporate and Runoff. Under these divisions, there are six operating business segments. The Insurance and Wealth Management Division includes the following operating business segments: U.S. Life Insurance (which includes the life insurance, long-term care insurance and fixed annuities businesses), International Protection (which includes the lifestyle protection insurance business) and Wealth Management. The Mortgage Insurance Division includes the following operating business segments: International Mortgage Insurance and U.S. Mortgage Insurance. The Corporate and Runoff Division includes the Runoff segment and Corporate and Other activities. The Runoff segment primarily includes variable annuities, Medicare supplement insurance and institutional products. Corporate and Other activities include interest and other debt financing expenses, other corporate income and expenses not allocated to the segments and other non-core businesses. These changes will allow the Company to sharpen its focus on common aspects within each group of businesses while taking advantage of current financial synergies. A revised financial supplement for the quarter ended September 30, 2011 reflecting the realigned segment reporting structure is furnished as Exhibit 99.1 to this Current Report on Form 8-K and is hereby incorporated by reference in this Item 2.02.

The revisions to the financial supplement relate solely to the presentation of segment specific disclosures (and do not reflect any subsequent accounting changes or fourth quarter results) and have no effect on the Company’s previously reported results of operations, financial condition or cash flows.

The information contained in this Current Report on Form 8-K (including the exhibit) is being furnished and shall not be deemed “filed” for the purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that Section. The information contained in this Current Report on Form 8-K shall not be incorporated by reference into any registration statement or other document pursuant to the Securities Act of 1933, as amended, or the Exchange Act, except as shall be expressly set forth by specific reference in any such filing.
