DEREGISTRATION OF SECURITIES

Anworth Mortgage Asset Corporation, a Maryland corporation (the “Company”), is filing this post-effective amendment to the Registration Statement on Form S-3 (File No. 333-230724), filed with the U.S. Securities and Exchange Commission on April 4, 2019 (the “Registration Statement”), to withdraw and deregister any and all securities that had been registered for sale and issuance under the Registration Statement and that remain unsold thereunder. The Registration Statement registered for sale and issuance shares of common stock, shares of preferred stock, and warrants, of the Company, or any combination thereof (collectively, the “Securities”).

On December 6, 2020, the Company, Ready Capital Corporation, a Maryland corporation (“Ready Capital”), and RC Merger Subsidiary, LLC, a Delaware limited liability company and a wholly owned subsidiary of Ready Capital (“Merger Sub”), entered into an Agreement and Plan of Merger, pursuant to which, subject to the terms and conditions therein, the Company merged with and into Merger Sub, with Merger Sub continuing as the surviving company (such transaction, the “Merger”). Immediately following the Merger, the surviving company was contributed to Ready Capital’s operating partnership subsidiary, Sutherland Partners, L.P., a Delaware limited partnership (the “Ready Capital Operating Partnership”), in exchange for units of limited partnership interests in the Ready Capital Operating Partnership. As a result of the contribution, the surviving company became a wholly-owned subsidiary of the Ready Capital Operating Partnership.

As a result of the consummation of the Merger, the Company has terminated all offerings and sales of its securities registered pursuant to its existing registration statements under the Securities Act of 1933, as amended, including the Registration Statement. In accordance with the undertakings made by the Company in the Registration Statement to remove from registration, by means of a post-effective amendment, any of the Securities that had been registered for sale and issuance but remain unsold at the termination of the offerings, the Company hereby removes and withdraws from registration any and all Securities registered pursuant to the Registration Statement that remain unsold as of the date hereof.
