Accounting Policies	NOTE 1 — Accounting Policies The condensed consolidated financial statements include the accounts of Cincinnati Financial Corporation and its consolidated subsidiaries, each of which is wholly owned. These statements are presented in conformity with accounting principles generally accepted in the United States of America (GAAP). All intercompany balances and transactions have been eliminated in consolidation. The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect amounts reported in the financial statements and accompanying notes. Our actual results could differ from those estimates. The December 31, 2010, condensed consolidated balance sheet amounts are derived from the audited financial statements but do not include all disclosures required by GAAP. Our September 30, 2011, condensed consolidated financial statements are unaudited. Certain financial information that is included in annual financial statements prepared in accordance with GAAP is not required for interim reporting and has been condensed or omitted. We believe that we have made all adjustments, consisting only of normal recurring accruals, that are necessary for fair presentation. These condensed consolidated financial statements should be read in conjunction with our consolidated financial statements included in our 2010 Annual Report on Form 10-K. The results of operations for interim periods do not necessarily indicate results to be expected for the full year. Adopted Accounting Updates ASU 2010-06, Fair Value Measurements and Disclosures In January 2010, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2010-06, Fair Value Measurements and Disclosures. ASU 2010-06 applies to all entities that are required to make disclosures about recurring or nonrecurring fair value measurements. ASU 2010-06 requires separate disclosures of the activity in the Level 3 category related to any purchases, sales, issuances and settlements on a gross basis. The effective date of these separate disclosures is for interim and annual periods beginning after December 15, 2010. This portion of ASU 2010-06 does not have a material impact on our company’s financial position, cash flows or results of operations as it focuses on additional disclosures. ASU 2010-15, How Investments Held through Separate Accounts Affect an Insurer’s Consolidation Analysis of Those Investments In April 2010, the FASB issued ASU 2010-15, How Investments Held through Separate Accounts Affect an Insurer’s Consolidation Analysis of Those Investments. ASU 2010-15 applies to all insurance entities that have separate accounts that meet the definition and requirements set forth in the Accounting Standards Codification Manual. ASU 2010-15 clarifies that an insurance entity should not consider any separate account interests held for the benefit of contract holders in an investment to be the insurer’s interests. The insurance entity should not combine those interests with its general account interest in the same investment when assessing the investment for consolidation. The insurance entity may combine those interests when the separate account interests are held for the benefit of a related-party policyholder as defined in the Variable Interest Subsections of the Consolidation topic in the Codification Manual. The effective date of the amendments in this update is for interim and annual periods beginning after December 15, 2010, with early adoption permitted. The amendments in this update do not modify the disclosures currently required by GAAP and do not have a material impact on our company’s financial position, cash flows or results of operations. Pending Accounting Updates ASU 2010-26, Accounting for Costs Associated with Acquiring or Renewing Insurance Contracts In October 2010, the FASB issued ASU 2010-26, Accounting for Costs Associated with Acquiring or Renewing Insurance Contracts. ASU 2010-26 modifies the definitions of the type of costs incurred by insurance entities that can be capitalized in the successful acquisition of new and renewal contracts. ASU 2010-26 requires capitalization of incremental direct costs of successful contract acquisition as well as certain costs related to underwriting, policy issuance and processing, medical and inspection and sales force contract selling for successful contract acquisition. These incremental direct costs and other costs are those that are essential to the contract transaction and would not have been incurred had the contract transaction not occurred. The effective date of ASU 2010-26 is for interim and annual reporting periods beginning after December 15, 2011. We plan to adopt ASU 2010-26 retrospectively. We estimate that at September 30, 2011, approximately $100 million of the total $512 million deferred acquisition costs asset is subject to further analysis to determine what can continue to be capitalized. We estimate $35-65 million of the $100 million may relate to successful acquisition of new and renewal contracts and will be deferrable and capitalized. The ASU has not yet been adopted, and we will report at December 31, 2011, the impact it will have on our company’s financial position, cash flows or results of operations. ASU 2011-04, Fair Value Measurements, Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRS In May 2011, the FASB issued ASU 2011-04, Fair Value Measurements, Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and International Financial Reporting Standards (IFRS). The ASU converges fair value measurement and disclosures among U.S. GAAP and IFRS. ASU 2011-04 changes certain fair value measurement principles and expands disclosure requirements, particularly for Level 3 inputs. The ASU is effective for interim and annual periods beginning after December 15, 2011, and should be applied prospectively. The ASU has not yet been adopted and will not have a material impact on our company’s financial position, cash flows or results of operations. ASU 2011-05, Presentation of Comprehensive Income In June 2011, the FASB issued ASU 2011-05, Presentation of Comprehensive Income. ASU 2011-05 requires entities to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. The ASU is effective for interim and annual reporting periods beginning after December 15, 2011, and should be applied prospectively. The ASU has not yet been adopted and will not have a material impact on our company’s financial position, cash flows or results of operations, as it relates to modified presentation of existing financial statements.
