Re: CNA Financial Corporation Form 10-K for the Fiscal Year Ended December 31, 2012 Filed February 21, 2013 File No. 001-05823

VIA EDGAR FILING

Dear Mr. Rosenberg:

We acknowledge receipt of the letter of comment dated August 1, 2013 from the Commission (the “Comment Letter”) with regard to the above-referenced filing.

Our response to the Comment Letter is set forth below. For your convenience, the staff's comment has been repeated herein and is followed by our response. CNA Financial Corporation (CNAF) and its subsidiaries are referred to as “the Company,” “CNA,” “we,” “our” and “us.”

Notes to Consolidated Financial Statements

Note I. Reinsurance, page 105

1. We acknowledge your response to our previous comment. Please address the following:

• As it relates to your “significant captive program” disclosed on pages 106 and 107, provide us proposed revised disclosure to be included in future periodic reports that explains the nature and type of coverage written and the business purpose of reinsuring 100% of the business with third-party captive insurance companies.

• As it relates to your captive program with third-party captive insurance companies owned by or related to the policyholder beyond your “significant captive program” tell us the significance of the program and how it differs from your “significant captive program” in nature and business purpose.

• Tell us whether the ceding commission you receive from third-party captives is equal to the premium you charge the policyholder. If so, tell us why you would enter into these arrangements if there is no apparent margin in it for you. If not, tell us why the policyholder would enter into these arrangements when it could transact directly with its captive.

CNA Response

A captive insurance program is one approach that third-party insureds can use to self-insure all or a portion of their risk. Captives are widely used by policyholders in many industries.

Generally under this approach, the third-party policyholder, or an entity related to the policyholder, forms and capitalizes a captive insurance company. The captive is licensed as a reinsurer, therefore the business

must be written though a primary insurance company. All or a portion of the risk written by the primary insurance company is then ceded to the captive reinsurer. The primary insurer receives a ceding commission to cover related costs such as premium taxes and insurance assessments as well providing compensation for the commitment of surplus necessary to support the business. Captives generally provide collateral to support ceded reserves. Receivable and payable balances between the parties are settled on a regular basis.

As noted in our prior response, the premiums and losses related to the significant captive program are 100% ceded to third-party captive insurance companies owned by wireless providers. Under this structure the wireless providers self-insure all of the risk related to the coverage of loss, theft, physical damage and warranty coverage for mechanical failure of the portable electronic devices they sell. CNA receives a ceding commission as compensation. In 2012, the commission related to the significant captive program increased net income by $16 million.

The other third-party captive programs referenced in our prior response operate in a similar manner; however, they are not material from either a gross premium or net income perspective.

In future filings of our Annual Report on Form 10-K, we will provide enhanced disclosure clarifying that the significant captive program relates to third-party non-insurance company policyholders. For purposes of illustration, had we added this enhanced disclosure to our 2012 Annual report on Form 10-K, the following would appear in Note I. Reinsurance on pages 105 and 106 (new language in italics and deleted language in strike-through).

Included in the direct and ceded earned premiums for the years ended December 31, 2012, 2011 and 2010 are $1,794 million, $1,500 million and $1,383 million related to property business that is 100% reinsured as a result ofunder a significant third-party captive program. The third-party captives that participate in this program are affiliated with the non-insurance company policyholders, therefore this program provides a means for the policyholders to self-insure this property risk. The Company receives and retains a ceding commission.
