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 (see General Instruction A.2 below):

On December 10, 2013, Genworth Holdings, Inc. (“Genworth Holdings”), a direct, wholly-owned subsidiary of Genworth Financial, Inc. (“Genworth Financial”), completed a public offering of $400 million aggregate principal amount of its 4.800% Senior Notes due 2024 (the “Notes”). The Notes are fully and unconditionally guaranteed (the “Guarantee”) on a senior unsecured basis by Genworth Financial. The Notes are governed by an Indenture, dated as of June 15, 2004 (the “Base Indenture”), between Genworth Holdings and The Bank of New York Mellon Trust Company, N.A., as trustee (the “Trustee”), as heretofore supplemented and as further supplemented by Supplemental Indenture No. 11, dated as of December 10, 2013 (“Supplemental Indenture No. 11”), among Genworth Holdings, Genworth Financial and the Trustee (as so supplemented, the “Indenture”).

The Notes are senior unsecured obligations of Genworth Holdings and rank equally in right of payment with all of Genworth Holdings’ other unsecured and unsubordinated obligations from time to time outstanding. The Notes are fully and unconditionally guaranteed on an unsecured and unsubordinated basis by Genworth Financial, and the guarantee will rank equally in right of payment with all of Genworth Financial’s other unsecured and unsubordinated obligations from time to time outstanding. Interest on the Notes will be payable semiannually in arrears on February 15 and August 15 of each year, beginning on February 15, 2014. Interest on the Notes will accrue from December 10, 2013.

Genworth Holdings may redeem all or a portion of the Notes at its option at any time or from time to time at a redemption price equal to the greater of:

The net proceeds of this offering (before expenses) were approximately $397 million. We currently expect to use the net proceeds from this offering (to the extent needed) to make a capital contribution to one or more of our U.S. mortgage insurance subsidiaries to satisfy all or a part of the higher capital requirements expected to be imposed by government-owned and government-sponsored enterprises (“GSEs”) as a part of the anticipated revisions to their eligibility standards for qualifying mortgage insurers.

In the event the capital requirements from the new eligibility standards exceed the net proceeds raised in this offering, we will consider a variety of funding options, including executing reinsurance transactions in our U.S. mortgage insurance business that provide capital benefits, using proceeds from the proposed partial initial public offering of our Australia mortgage insurance business, using cash at Genworth Holdings in excess of our targets, using available deferred tax assets, using proceeds from the issuance of new debt or equity securities (including convertible, exchangeable or other hybrid securities) at the Genworth Financial and/or Genworth Holdings level, and/or using proceeds from a third-party capital raise by our U.S. mortgage insurance subsidiaries or earnings growth from those subsidiaries.

To the extent all of the proceeds are not required for the expected uses, or we otherwise decide not to use them for those purposes, the net proceeds will be used for general corporate purposes. Pending the expected uses, we may invest the net proceeds in short-term, liquid obligations.

Although we incurred additional debt in this offering, we have been working to reduce our leverage through actions such as those recently taken, including designating proceeds from the sale of our wealth management business to address near term debt maturities. Subsequent to this offering, we will continue to focus on improving the operating performance of our businesses and reducing leverage over the medium term.
