The securities identified are held by the following subsidiaries in the following amounts: Continental Casualty Company (26,612,258 shares) and The Continental Insurance Company (812,889 shares). The characterization of shared dispositive power with the parent company is made solely as a consequence of SEC interpretations regarding control of the subsidiaries.

This Amendment No. 3 amends the statement on Schedule 13D (the “Schedule 13D”) filed with the Securities and Exchange Commission (“SEC”) on March 27, 2000 by Continental Casualty Company, an Illinois insurance company (“Continental”), CNA Financial Corporation, a Delaware corporation (“CNAF”), and Loews Corporation ("Loews"), a Delaware corporation, as amended by Amendment No. 1 filed on May 31, 2000 and by Amendment No. 2 filed on November 1, 2010.

Item 3. Sources and Amount of Funds or Other Considerations.

Item 3 of Schedule 13D is hereby amended by inserting the following at the end thereof:

CNAF estimates that the aggregate consideration that would be required to acquire the shares of Common Stock in the transaction described in Item 4 would be approximately $475 million. The shares of Common Stock that would be acquired in connection with the transaction would be purchased with working capital of subsidiaries of CNAF.

Item 4. Purpose of Transaction.

Item 4 of Schedule 13D is hereby amended by inserting the following at the end thereof:

On April 20, 2011, CNAF, Surety Acquisition Corporation (“Merger Sub”), a newly formed Delaware corporation that is an indirect wholly owned subsidiary of CNAF, and CNA Surety Corporation, a Delaware corporation (“Surety”), entered into an Agreement and Plan of Merger (the “Merger Agreement”).

Pursuant to the Merger Agreement, Merger Sub will, as soon as practicable, commence a tender offer (the “Offer”) to acquire all of the outstanding shares of Common Stock of CNA Surety that subsidiaries of CNAF do not currently own for a purchase price of $26.55 in cash per share. The Merger Agreement has been approved by the board of directors of Surety following the recommendation and approval of a Special Committee consisting of Surety’s three independent directors.

A copy of the Merger Agreement is filed as Exhibit G to this Schedule 13D, and is incorporated by reference into this Item 4. Following the execution of the Merger Agreement, CNAF and Surety issued a joint press release, a copy of which is filed as Exhibit H to this Schedule 13D, and is incorporated by reference into this Item 4. The foregoing description of the Merger Agreement, and the transactions contemplated thereby does not purport to be complete and is subject to, and qualified in its entirety by reference to, the full text of the Merger Agreement.

The Offer and the transactions contemplated by the Merger Agreement would result in one or more of the actions specified in clauses (a) — (j) of Item 4 of Schedule 13D, including the acquisition of additional securities of Surety, a merger or other extraordinary transaction involving Surety, changes to Surety’s certificate of incorporation and bylaws, the delisting of the shares of Common Stock of Surety from the New York Stock Exchange and the shares of Common Stock of Surety becoming eligible for termination of registration pursuant to Section 12(g)(4) of the Act.

This Schedule 13D is not an offer to purchase or a solicitation of an offer to sell any securities. The tender offer described in this Schedule 13D has not yet commenced. At the time the tender offer is commenced, CNAF will file a tender offer statement on Schedule TO with the SEC. CNA Surety stockholders and other interested parties are urged to read these materials when they become available because they will contain important information. CNA Surety stockholders will be able to obtain such documents (when available) free of charge at the SEC’s web site, www.sec.gov. CNA Surety stockholders will also be able to obtain the documents that are filed by CNA (when available) for free from CNA at www.cna.com or at 333 South Wabash Avenue, Chicago, Illinois 60604.
