| Business Segments                | Note K. Business SegmentsThe Company's core property and casualty commercial insurance operations are reported in three business segments:  CNA Specialty, CNA Commercial and Hardy.  The Company's non-core operations are managed in two segments: Life & Group Non-Core and Corporate & Other Non-Core.The accounting policies of the segments are the same as those described in Note A of the Consolidated Financial Statements within CNAF's Annual Report on Form 10-K for the year ended December 31, 2013.  The Company manages most of its assets on a legal entity basis, while segment operations are generally conducted across legal entities.  As such, only insurance and reinsurance receivables, insurance reserves, deferred acquisition costs and goodwill are readily identifiable for all individual segments.  Distinct investment portfolios are not maintained for every individual segment; accordingly, allocation of assets to each segment is not performed.  Therefore, a significant portion of net investment income and realized investment gains or losses are allocated primarily based on each segment's net carried insurance reserves, as adjusted.  All significant intersegment income and expense has been eliminated.  Income taxes have been allocated on the basis of the taxable income of the segments.In the following tables, certain financial measures are presented to provide information used by management to monitor the Company's operating performance.  Management utilizes these financial measures to monitor the Company's insurance operations and investment portfolio.  Net operating income, which is derived from certain income statement amounts, is used by management to monitor performance of the Company's insurance operations.  The Company's investment portfolio is monitored by management through analysis of various factors including unrealized gains and losses on securities, portfolio duration and exposure to market and credit risk.  Based on such analyses, the Company may recognize an OTTI loss on an investment security in accordance with its policy, or sell a security, which may produce realized gains and losses.Net operating income (loss) is calculated by excluding from net income (loss) the after-tax effects of 1) net realized investment gains or losses, 2) income or loss from discontinued operations and 3) any cumulative effects of changes in accounting guidance.  The calculation of net operating income excludes net realized investment gains or losses because net realized investment gains or losses are largely discretionary, except for some losses related to OTTI, and are generally driven by economic factors that are not necessarily consistent with key drivers of underwriting performance, and are therefore not considered an indication of trends in insurance operations.The results of the Company's continuing operations and selected balance sheet items are presented in the following tables.Three months ended June 30, 2014CNASpecialty
