Definitions and Presentation

•		Collectively, CNA Financial Corporation (CNAF) and its controlled subsidiaries are referred to as CNA or the Company.
•		P&C Operations includes CNA Specialty and CNA Commercial.
•		Life & Group Non-Core segment primarily includes the results of the life and group lines of business that are in run-off.
•		Corporate & Other Non-Core segment primarily includes certain corporate expenses including interest on corporate debt and the results of certain property and casualty business in run-off, including CNA Re and asbestos and environmental pollution (A&EP). Intersegment eliminations are also included in this segment.
•		Management utilizes the net operating income financial measure to monitor the Company’s operations. Please refer to Note K of the Condensed Consolidated Financial Statements within the September 30, 2010 Form 10-Q for further discussion of this measure.
•		In evaluating the results of CNA Specialty and CNA Commercial, management utilizes the combined ratio, the loss ratio, the expense ratio and the dividend ratio. These ratios are calculated using financial results prepared in accordance with accounting principles generally accepted in the United States of America. The loss ratio is the percentage of net incurred claim and claim adjustment expenses to net earned premiums. The expense ratio is the percentage of insurance underwriting and acquisition expenses, including the amortization of deferred acquisition costs, to net earned premiums. The dividend ratio is the ratio of policyholders’ dividends incurred to net earned premiums. The combined ratio is the sum of the loss, expense and dividend ratios.
•		Certain immaterial differences are due to rounding.

Segment Change — Certain Mass Tort Claims

The Company has revised its reporting segments in the fourth quarter of 2010. The segment change reflects the manner in which the Company is currently organized for purposes of making operating decisions and assessing performance. This Financial Supplement presents segment data for prior reporting periods adjusted to reflect the new segment reporting.

Net incurred claim and claim adjustment expenses and reserves for certain mass tort claims were previously reported as part of the Corporate & Other Non-Core segment. These mass tort claims were centrally managed along with asbestos and environmental pollution claims. A significant portion of this centralized claim group became employees of a subsidiary of Berkshire Hathaway Inc. as a result of the previously announced Loss Portfolio Transfer transaction that closed on August 31, 2010. Management responsibility for these mass tort claims has now been assigned to the segment from which the mass tort arose, which could be either CNA Specialty or CNA Commercial. This change had no impact on the Company’s CNA Specialty and Life & Group Non-Core segments for the periods presented herein.
