Item 1.01. Entry into a Material Definitive Agreement.

On November 14, 2006, Genworth Financial, Inc. (the “Registrant”) completed a public offering of $600,000,000 aggregate principal amount of the Registrant’s 6.15% Fixed-to-Floating Rate Junior Subordinated Notes due 2066 (the “Notes”). The Notes are governed by an Indenture, dated as of November 14, 2006 (the “Base Indenture”), as supplemented by the First Supplemental Indenture, dated as of November 14, 2006 (the “First Supplemental Indenture”), each between the Registrant and The Bank of New York Trust Company, N.A., as trustee (the Base Indenture, as so supplemented by the First Supplemental Indenture, the “Indenture”). The Notes will bear interest on their principal amount from November 14, 2006 to but excluding November 15, 2016 at the annual rate of 6.15%, payable semi-annually in arrears, and from and including November 15, 2016 to but excluding November 15, 2066 at an annual rate equal to three-month LIBOR plus 2.0025%, payable quarterly in arrears. The Notes are redeemable on November 15, 2036, or thereafter, to the extent sufficient proceeds are raised from the sale of certain replacement capital securities, or on November 15, 2066 if the Registrant is unable to raise such proceeds.

The Notes were issued pursuant to an underwriting agreement (the “Underwriting Agreement”), dated as of November 7, 2006, between the Registrant and Morgan Stanley & Co. Incorporated, Deutsche Bank Securities Inc. and Goldman, Sachs & Co., as underwriters (the “Underwriters”). Pursuant to the Underwriting Agreement and subject to the terms and conditions expressed therein, the Registrant agreed to sell the Notes to the Underwriters, and the Underwriters agreed to purchase the Notes for resale to the public. The Registrant sold the Notes to the Underwriters at an issue price of 98.712% of the principal amount thereof, and the Underwriters offered the Notes to the public at a price of 99.712% of the principal amount thereof. The net proceeds of this offering were approximately $592 million. The Registrant intends to use approximately $319 million of the net proceeds to reduce its outstanding commercial paper borrowings and the remainder of the net proceeds for general corporate purposes.

On November 14, 2006, in connection with the completion of the offering of the Notes, the Registrant entered into a Replacement Capital Covenant (the “Replacement Capital Covenant”), whereby the Registrant agreed for the benefit of holders of a specified series of the Registrant’s long-term indebtedness ranking senior to the Notes that the Notes will not be repaid, redeemed or repurchased by the Registrant on or before November 15, 2046, unless such repayment, redemption or repurchase is made from the proceeds of the issuance of certain replacement capital securities and pursuant to the other terms and conditions set forth in the Replacement Capital Covenant.

The Notes were offered and sold by the Registrant pursuant to its registration statement on Form S-3 (File No. 333-138437).

The foregoing descriptions of the Indenture, the Replacement Capital Covenant and the Underwriting Agreement do not purport to be complete and are qualified in their entirety by

reference to the full text of the Base Indenture, the First Supplemental Indenture, the Replacement Capital Covenant and the Underwriting Agreement, each of which is filed as an exhibit hereto and is incorporated by reference herein.
