NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

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. Our December 31, 2012, condensed consolidated balance sheet amounts are derived from the audited financial statements but do not include all disclosures required by GAAP.

Our June 30, 2013, 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 2012 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 2013-02, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income

In February 2013, the Financial Accounting Standards Board issued Accounting Standards Update (ASU) 2013-02, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income. ASU 2013-02 requires entities to present in either a single note or parenthetically on the face of the financial statements, the effect of significant amounts reclassified from each component of accumulated other comprehensive income based on its source and the income statement line items affected by the reclassification. The company adopted this ASU during the first quarter of 2013, and it did not have a material impact on our company’s financial position, cash flows or results of operations. See Note 7, Accumulated Other Comprehensive Income, for further details.

The net unrealized investment gains in our fixed-maturity portfolio are primarily the result of the current low interest rate environment that increased the fair value of our fixed-maturity portfolio. The three largest net unrealized investment gains in our common stock portfolio are from Exxon Mobil Corporation (NYSE:XOM), Chevron Corporation (NYSE:CVX) and The Procter & Gamble Company (NYSE:PG), which had a combined net gain position of $283 million. At At June 30, 2013, we had $16 million fair value of hybrid securities included in fixed maturities that follow Accounting Standards Codification (ASC) 815-15-25, Accountingfor Certain Hybrid Financial Instruments, compared with $31 million fair value of hybrid securities at December 31, 2012. The hybrid securities are carried at fair value, and the changes in fair value are included in realized investment gains and losses.

NOTE 3 – FAIR VALUE MEASUREMENTS

Fair Value Hierarchy

In accordance with accounting guidance for fair value measurements and disclosures, we categorized our financial instruments, based on the priority of the observable and market-based data for the valuation technique used, into a three-level fair value hierarchy. The fair value hierarchy gives the highest priority to quoted prices with readily available independent data in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable market inputs (Level 3). When various inputs for measurement fall within different levels of the fair value hierarchy, the lowest observable input that has a significant impact on fair value measurement is used. Our valuation techniques have not changed from those used at December 31, 2012, and ultimately management determines fair value. See our 2012 Annual Report on Form 10-K, Item 8, Note 3, Fair Value Measurements, Page 121, for information on characteristics and valuation techniques used in determining fair value.

Fair Value Disclosures for Assets

The following tables illustrate the fair value hierarchy for those assets measured at fair value on a recurring basis at June 30, 2013, and December 31, 2012. We do not have any material liabilities carried at fair value. There were no transfers between Level 1 and Level 2.

Each financial instrument that was deemed to have significant unobservable inputs when determining valuation is identified in the following tables by security type with a summary of changes in fair value as of June 30, 2013. Total Level 3 assets continue to be less than 1 percent of financial assets measured at fair value in the condensed consolidated balance sheets. Assets presented in the table below were valued based primarily on broker/dealer quotes for which there is a lack of transparency as to inputs used to develop the valuations. The quantitative detail of these unobservable inputs is neither provided nor reasonably available to us.

NOTE 4 – PROPERTY CASUALTY LOSS AND LOSS EXPENSES

This table summarizes activity for our consolidated property casualty loss and loss expense reserves:

(In millions)	Three months ended June 30,						Six months ended June 30,
	2013			2012			2013			2012
Gross loss and loss expense reserves, beginning of period	$	4,173		$	4,289		$	4,169		$	4,280
Less reinsurance receivable	349			352			356			375
Net loss and loss expense reserves, beginning of period	3,824			3,937			3,813			3,905
Net incurred loss and loss expenses related to:
Current accident year	675			725			1,209			1,380
Prior accident years	(92		)	(85		)	(102		)	(201		)
Total incurred	583			640			1,107			1,179
Net paid loss and loss expenses related to:
Current accident year	249			282			370			414
Prior accident years	272			290			664			665
Total paid	521			572			1,034			1,079
Net loss and loss expense reserves, end of period	3,886			4,005			3,886			4,005
Plus reinsurance receivable	333			332			333			332
Gross loss and loss expense reserves, end of period	$	4,219		$	4,337		$	4,219		$	4,337

We use actuarial methods, models and judgment to estimate, as of a financial statement date, the property casualty loss and loss expense reserves required to pay for and settle all outstanding insured claims, including incurred but not reported (IBNR) claims, as of that date. The actuarial estimate is subject to review and adjustment by an inter-departmental committee that includes actuarial management that is familiar with relevant company and industry business, claims and underwriting trends, as well as general economic and legal trends that could affect future loss and loss expense payments. The amount we will actually have to pay for claims can be highly uncertain. This uncertainty, together with the size of our reserves, makes the loss and loss expense reserves our most significant estimate. The reserve for loss and loss expenses in the condensed consolidated balance sheets also included $65 million at June 30, 2013, and $59 million at June 30, 2012, for certain life and health loss and loss expense reserves.

For the three months ended June 30, 2013, we experienced $92 million of favorable development on prior accident years, including $66 million of favorable development in commercial lines and $26 million of favorable development in personal lines. There was $8 million from favorable development of catastrophe losses for the three months ended June 30, 2013, compared with $5 million of favorable development of catastrophe losses that occurred for the three months ended June 30, 2012.

For the six months ended June 30, 2013, we experienced $102 million of favorable development on prior accident years, including $78 million of favorable development in commercial lines, $22 million of favorable development in personal lines and $2 million favorable development in excess and surplus lines. There was $15 million from favorable development of catastrophe losses for the six months ended June 30, 2013, compared with $27 million of favorable development of catastrophe losses that occurred for the six months ended June 30, 2012.

NOTE 5 – LIFE POLICY AND INVESTMENT CONTRACT RESERVES

We establish the reserves for traditional life insurance policies based on expected expenses, mortality, morbidity, withdrawal rates, timing of claim presentation and investment yields, including a provision for uncertainty. Once these assumptions are established, they generally are maintained throughout the lives of the contracts. We use both our own experience and industry experience, adjusted for historical trends, in arriving at our assumptions for expected mortality, morbidity and withdrawal rates as well as for expected expenses. We base our assumptions for expected investment income on our own experience adjusted for current economic conditions.

We establish reserves for the company’s universal life, deferred annuity and structured settlement policies equal to the cumulative account balances, which include premium deposits plus credited interest less charges and withdrawals. Some of our universal life policies contain no-lapse guarantee provisions. For these policies, we establish a reserve in addition to the account balance, based on expected no-lapse guarantee benefits and expected policy assessments.

This table summarizes our life policy and investment contract reserves:

(In millions)	June 30, 2013		December 31, 2012
Ordinary/traditional life	$	778	$	752
Universal life	501		483
Deferred annuities	858		850
Structured settlements	192		193
Other	16		17
Total life policy and investment contract reserves	$	2,345	$	2,295

NOTE 6 – DEFERRED ACQUISITION COSTS

Expenses directly related to successfully acquiring insurance policies – primarily commissions, premium taxes and underwriting costs – are deferred and amortized over the terms of the policies. We update our acquisition cost assumptions periodically to reflect actual experience, and we evaluate the costs for recoverability. The table below shows the deferred policy acquisition costs and asset reconciliation.

(In millions)	Three months ended June 30,						Six months ended June 30,
	2013			2012			2013			2012
Deferred policy acquisition costs asset at beginning of period	$	491		$	483		$	470		$	477
Capitalized deferred policy acquisition costs	203			192			401			362
Amortized deferred policy acquisition costs	(183		)	(181		)	(362		)	(337		)
Amortized shadow deferred policy acquisition costs	35			(10		)	37			(18		)
Deferred policy acquisition costs asset at end of period	$	546		$	484		$	546		$	484

No premium deficiencies were recorded in the condensed consolidated statements of income, as the sum of the anticipated loss and loss adjustment expenses, policyholder dividends and unamortized deferred acquisition expenses did not exceed the related unearned premiums and anticipated investment income.

NOTE 8 – REINSURANCE

Reinsurance mitigates the risk of highly uncertain exposures and limits the maximum net loss that can arise from large risks or risks concentrated in areas of exposure. Management's decisions about the appropriate level of risk retention are affected by various factors, including changes in our underwriting practices, capacity to retain risks and reinsurance market conditions. Primary components of our property and casualty reinsurance program include a property per risk treaty, property excess treaty, casualty per occurrence treaty, casualty excess treaty, property catastrophe treaty and catastrophe bonds.

Our condensed consolidated statements of income include earned consolidated property casualty insurance premiums on assumed and ceded business: 

(In millions)	Three months ended June 30,						Six months ended June 30,

Net incurred loss and loss expenses	$	583		$	640		$	1,107		$	1,179

Our life insurance company purchases reinsurance for protection of a portion of the risk that is written. Primary components of our life reinsurance program include individual mortality coverage and aggregate catastrophe and accidental death coverage in excess of certain deductibles.

Our condensed consolidated statements of income include earned life insurance premiums on ceded business: 

(In millions)	Three months ended June 30,						Six months ended June 30,

NOTE 9 – INCOME TAXES

As of June 30, 2013, and December 31, 2012, we had no liability for unrecognized tax benefits. Details about our liability for unrecognized tax benefits are found in our 2012 Annual Report on Form 10-K, Item 8, Note 11, Income Taxes, Page 129.

The differences between the 35 percent statutory income tax rate and our effective income tax rate were as follows:

(Dollars in millions)	Three months ended June 30,										Six months ended June 30,
	2013					2012					2013					2012
Tax at statutory rate	$	52		35.0	%	$	10		35.0	%	$	128		35.0	%	$	49		35.0	%
Increase (decrease) resulting from:
Tax-exempt income from municipal bonds	(9		)	(6.1	)	(8		)	(27.6	)	(16		)	(4.4	)	(17		)	(12.1	)
Dividend received exclusion	(6		)	(4.2	)	(6		)	(20.7	)	(12		)	(3.3	)	(11		)	(7.8	)
Other	1			1.0		1			3.0		1			0.4		2			1.2
Provision (benefit) for income taxes	$	38		25.7	%	$	(3	)	(10.3	)%	$	101		27.7	%	$	23		16.3	%

The change in our effective tax rate was primarily due to changes in pretax income from underwriting results and realized investment gains and losses, compared with unchanged levels of permanent book-tax differences.

NOTE 10 – NET INCOME PER COMMON SHARE

Basic earnings per share are computed based on the weighted average number of shares outstanding. Diluted earnings per share are computed based on the weighted average number of common and dilutive potential common shares outstanding using the treasury stock method.

The table shows calculations for basic and diluted earnings per share:

The current sources of dilution of our common shares are certain equity-based awards as discussed in our 2012 Annual Report on Form 10-K, Item 8, Note 17, Stock-Based Associate Compensation Plans, Page 135. The above table shows the number of anti-dilutive stock-based awards for the three and six months ended June 30, 2013 and 2012. We did not include these stock-based awards in the computation of net income per common share (diluted) because their exercise would have anti-dilutive effects.

We contributed $15 million to our qualified pension plan during the first quarter of 2013. We do not anticipate further contributions to our qualified pension plan during the remainder of 2013.

NOTE 12 – COMMITMENTS AND CONTINGENT LIABILITIES

In the ordinary course of conducting business, the company and its subsidiaries are named as defendants in various legal proceedings. Most of these proceedings are claims litigation involving the company's insurance subsidiaries in which the company is either defending or providing indemnity for third-party claims brought against insureds or litigating first-party coverage claims. The company accounts for such activity throughthe establishment of unpaid loss and loss adjustment expense reserves. We believe that the ultimate liability, if any, with respect to such ordinary-course claims litigation, after consideration of provisions made for potential losses and costs of defense, is immaterial to our consolidated financial condition, results of operations and cash flows.

The company and its subsidiaries also are occasionally involved in other legal and regulatory proceedings, some of which assert claims for substantial amounts. These actions include, among others, putative class actions seeking certification of a state or national class. Such proceedings have alleged, for example, breach of an alleged duty to search national data bases to ascertain unreported deaths of insureds underlife insurance policies. The company's insurance subsidiaries also are occasionally parties to individual actions in which extra-contractual damages, punitive damages or penalties are sought, such asclaims alleging bad faith handling of insuranceclaims or writing unauthorized coverage and claims alleging discrimination by formerassociates.

On a quarterly basis, we review these outstanding matters. Under current accounting guidance, we establish accruals when it is probable that a loss has been incurred and we can reasonably estimate its potential exposure. The company accounts for such probable and estimable losses, if any, through the establishment of legal expense reserves. Based on our quarterly review, we believe that our accruals for probable and estimable losses are reasonable and that the amounts accrued do not have a material effect on our consolidated financial condition or results of operations. However, if any one or more of these matters results in a judgment against us or settlement for an amount that is significantly greater than the amount accrued, the resulting liability could have a material effect on the company's consolidated results of operations or cash flows. Based on our most recent review, our estimate for any other matters for which the risk of loss is not probable, but more than remote is less than $2 million.

Item 2.    Management’s Discussion and Analysis of Financial Condition and

Results of Operations

The following discussion highlights significant factors influencing the consolidated results of operations and financial position of Cincinnati Financial Corporation (CFC). It should be read in conjunction with the consolidated financial statements and related notes included in our 2012 Annual Report on Form 10-K. Unless otherwise noted, the industry data is prepared by A.M. Best Co., a leading insurance industry statistical, analytical and financial strength rating organization. Information from A.M. Best is presented on a statutory basis. When we provide our results on a comparable statutory basis, we label it as such; all other company data is presented in accordance with accounting principles generally accepted in the United States of America (GAAP).

We present per share data on a diluted basis unless otherwise noted, adjusting those amounts for all stock splits and dividends. Dollar amounts are rounded to millions; calculations of percent changes are based on dollar amounts rounded to the nearest million. Certain percentage changes are identified as not meaningful (nm).

SAFE HARBOR STATEMENT

This is our “Safe Harbor” statement under the Private Securities Litigation Reform Act of 1995. Our business is subject to certain risks and uncertainties that may cause actual results to differ materially from those suggested by the forward-looking statements in this report. Some of those risks and uncertainties are discussed in our 2012 Annual Report on Form 10-K, Item 1A, Risk Factors, Page 26.

Factors that could cause or contribute to such differences include, but are not limited to:

• Unusually high levels of catastrophe losses due to risk concentrations, changes in weather patterns, environmental events, terrorism incidents or other causes

• Increased frequency and/or severity of claims

• Inadequate estimates or assumptions used for critical accounting estimates

• Recession or other economic conditions resulting in lower demand for insurance products or increased payment delinquencies

• Declines in overall stock market values negatively affecting the company’s equity portfolio and book value

• Events resulting in capital market or credit market uncertainty, followed by prolonged periods of economic instability or recession, that lead to:

◦ Significant or prolonged decline in the value of a particular security or group of securities and impairment of the asset(s)

◦ Significant decline in investment income due to reduced or eliminated dividend payouts from a particular security or group of securities

◦ Significant rise in losses from surety and director and officer policies written for financial institutions or other insured entities

• Prolonged low interest rate environment or other factors that limit the company’s ability to generate growth in investment income or interest rate fluctuations that result in declining values of fixed-maturity investments, including declines in accounts in which we hold bank-owned life insurance contract assets

• Increased competition that could result in a significant reduction in the company’s premium volume

• Delays or performance inadequacies from ongoing development and implementation of underwriting and pricing methods or technology projects and enhancements expected to increase our pricing accuracy, underwriting profit and competitiveness

• Changing consumer insurance-buying habits and consolidation of independent insurance agencies that could alter our competitive advantages

• Inability to obtain adequate reinsurance on acceptable terms, amount of reinsurance purchased, financial strength of reinsurers and the potential for nonpayment or delay in payment by reinsurers

• Difficulties with technology or data security breaches, including cyber attacks, that could negatively affect our ability to conduct business and our relationships with agents, policyholders and others

Cincinnati Financial Corporation Second-Quarter 2013 10-Q

Page 25

• Inability to defer policy acquisition costs for any business segment if pricing and loss trends would lead management to conclude that segment could not achieve sustainable profitability

• Events or conditions that could weaken or harm the company’s relationships with its independent agencies and hamper opportunities to add new agencies, resulting in limitations on the company’s opportunities for growth, such as:

◦ Downgrades of the company’s financial strength ratings

◦ Concerns that doing business with the company is too difficult

◦ Perceptions that the company’s level of service, particularly claims service, is no longer a distinguishing characteristic in the marketplace

• Actions of insurance departments, state attorneys general or other regulatory agencies, including a change to a federal system of regulation from a state-based system, that:

◦ Impose new obligations on us that increase our expenses or change the assumptions underlying our critical accounting estimates

◦ Place the insurance industry under greater regulatory scrutiny or result in new statutes, rules and regulations

◦ Restrict our ability to exit or reduce writings of unprofitable coverages or lines of business

◦ Add assessments for guaranty funds, other insurance related assessments or mandatory reinsurance arrangements; or that impair our ability to recover such assessments through future surcharges or other rate changes

◦ Increase our provision for federal income taxes due to changes in tax law

◦ Increase our other expenses

◦ Limit our ability to set fair, adequate and reasonable rates

◦ Place us at a disadvantage in the marketplace

◦ Restrict our ability to execute our business model, including the way we compensate agents

• Adverse outcomes from litigation or administrative proceedings

• Events or actions, including unauthorized intentional circumvention of controls, that reduce the company’s future ability to maintain effective internal control over financial reporting under the Sarbanes-Oxley Act of 2002

• Unforeseen departure of certain executive officers or other key employees due to retirement, health or other causes that could interrupt progress toward important strategic goals or diminish the effectiveness of certain longstanding relationships with insurance agents and others

• Events, such as an epidemic, natural catastrophe or terrorism, that could hamper our ability to assemble our workforce at our headquarters location

Further, the company’s insurance businesses are subject to the effects of changing social, economic and regulatory environments. Public and regulatory initiatives have included efforts to adversely influence and restrict premium rates, restrict the ability to cancel policies, impose underwriting standards and expand overall regulation. The company also is subject to public and regulatory initiatives that can affect the market value for its common stock, such as measures affecting corporate financial reporting and governance. The ultimate changes and eventual effects, if any, of these initiatives are uncertain.

Revenues rose for the second quarter and the first six months of 2013 compared with the same periods of 2012, primarily due to growth in earned premiums. Premium and investment revenue trends are discussed further in the respective sections of Results of Operations.

Realized investment gains and losses are recognized on the sales of investments or as otherwise required by GAAP. We have substantial discretion in the timing of investment sales, and that timing generally is independent of the insurance underwriting process. GAAP also requires us to recognize in net income the gains or losses from certain changes in fair values of securities even though we continue to hold the securities.

Net income for the second quarter of 2013 compared with the second quarter of 2012 rose $78 million, primarily due to stronger property casualty underwriting income that rose $72 million after taxes. Lower catastrophe losses, mostly weather related, improved after-tax property casualty underwriting results by $47 million compared with the second quarter of 2012. After-tax investment income in our investment segment results for the second quarter of 2013 declined $1 million compared with the second quarter of 2012, while life insurance segment results on a pretax basis rose by $1 million. Second-quarter 2013 after-tax net realized investment gains and losses were $6 million higher than the same quarter a year ago.

For the six-month period ended June 30, 2013, net income increased $146 million compared with the same period of 2012, also primarily due to higher property casualty underwriting results that rose $117 million after taxes, including $98 million from lower catastrophe losses. After-tax investment income decreased by $3 million while after-tax net realized investment gains and losses were $23 million higher. Life insurance segment results on a pretax basis were $11 million higher.

Performance by segment is discussed below in Results of Operations. As discussed in our 2012 Annual Report on Form 10-K, Item 7, Factors Influencing Our Future Performance, Page 42, there are several reasons that our performance during 2013 may be below our long-term targets. In that annual report, as part of Results of Operations, we also discussed the full-year 2013 outlook for each reporting segment.

The board of directors is committed to rewarding shareholders directly through cash dividends and through share repurchase authorizations. Through 2012, the company had increased the indicated annual cash dividend rate for 52 consecutive years, a record we believe was matched by only nine other publicly traded companies. During the first six months of 2013, cash dividends declared by the company increased approximately 1 percent compared with the same period of 2012. Our board regularly evaluates relevant factors in decisions related to dividends and

share repurchases. Increasing the dividend in 2012 signaled management’s and the board’s confidence in our strong capital, liquidity and financial flexibility, as well as progress on our initiatives to improve earnings performance.

Balance Sheet Data and Performance Measures

(Dollars in millions except share data)	At June 30,			At December 31,
	2013			2012
Balance sheet data:
Invested assets	$	12,933		$	12,534
Total assets	17,034			16,548

Shareholders' equity	5,699			5,453
Book value per share	34.83			33.48
Debt-to-total-capital ratio	13.6		%	14.1		%

Total assets at June 30, 2013, increased 3 percent compared with year-end 2012, primarily due to growth in invested assets that was driven by additional purchases of securities. Shareholders’ equity rose 5 percent, and book value per share was up 4 percent during the first six months of 2013. Our debt-to-total-capital ratio (capital is the sum of debt plus shareholders’ equity) decreased compared with year-end 2012. The value creation ratio, a non-GAAP measure defined below, improved for the first six months of 2013 compared with 2012, reflecting higher unrealized investment gains and net income. The $1.35 increase in book value per share during the first six months of 2013 contributed 4.0 percentage points to the value creation ratio, while dividends declared at $0.815 per share contributed 2.4 points. Value creation ratio trends in total and by major components, along with a reconciliation of the non-GAAP measure to comparable GAAP measures, are shown in the tables below.

The cumulative effect of a change in accounting for deferred policy acquisition costs, net of tax, in the above book value reconciliation is the result of our adoption of Accounting Standards Update (ASU) 2010-26, Accounting for Costs Associated with Acquiring or Renewing Insurance Contracts. We retrospectively adopted this ASU on January 1, 2012. See our 2012 Annual Report on Form 10-K, Item 8, Note 1, Summary of Significant Accounting Policies, Page 112, for information on our adopted accounting standards.

PROGRESS TOWARD LONG-TERM VALUE CREATION

Operating through The Cincinnati Insurance Company, Cincinnati Financial Corporation is one of the 25 largest property casualty insurers in the nation, based on 2012 net written premium volume for approximately 2,000 U.S. stock and mutual insurer groups. We market our insurance products through a select group of independent insurance agencies in 39 states as discussed in our 2012 Annual Report on Form 10-K, Item 1, Our Business and Our Strategy, Page 3.

We maintain a long-term perspective that guides us in addressing immediate challenges or opportunities while focusing on the major decisions that best position our company for success through all market cycles. We believe that this forward-looking view has consistently benefited our policyholders, agents, shareholders and associates.

To measure our long-term progress in creating shareholder value, we have defined a value creation metric that we believe captures the contribution of our insurance operations, the success of our investment strategy and the importance we place on paying cash dividends to shareholders. This measure, our value creation ratio or VCR, is made up of two primary components: (1) our rate of growth in book value per share plus (2) the ratio of dividends declared per share to beginning book value per share. As discussed in our 2012 Annual Report on Form 10-K, Item 7, Executive Summary, Page 38, for the period 2013 through 2017, an annual value creation ratio averaging 10 percent to 13 percent is our primary performance target. Management believes this non-GAAP measure is a meaningful indicator of our long-term progress in creating shareholder value and is a useful supplement to GAAP information.

Performance Drivers

When looking at our long-term objectives, we see three performance drivers:

• Premium growth - We believe over any five-year period our agency relationships and initiatives can lead to a property casualty written premium growth rate that exceeds the industry average. For the first six months of 2013, our total property casualty net written premiums' year-over-year growth was 12 percent, comparing favorably with A.M. Best's February 2013 projection of approximately 5 percent full-year 2013 growth for the industry excluding its mortgage and financial guaranty lines of business. Our premium growth initiatives are discussed below in Highlights of Our Strategies and Supporting Initiatives.

• Combined ratio - We believe our underwriting philosophy and initiatives can generate a GAAP combined ratio over any five-year period that is consistently within the range of 95 percent to 100 percent. For the first six months of 2013, our GAAP combined ratio was 93.9 percent and our statutory combined ratio was 91.8 percent, both including 5.6 percentage points of current accident year catastrophe losses offset by 5.6 percentage points of favorable loss reserve development on prior accident years. As of February 2013, A.M. Best forecast the industry's full-year 2013 statutory combined ratio at approximately 101 percent, including approximately 5 percentage points of catastrophe losses and a favorable impact of approximately 3 percentage points from prior accident year reserve releases. The industry's ratio again excludes its mortgage and financial guaranty lines of business.

• Investment contribution - We believe our investment philosophy and initiatives can drive investment income growth and lead to a total return on our equity investment portfolio over a five-year period that exceeds the five-year return of the Standard & Poor's 500 Index. For the first six months of 2013, pretax investment income was $259 million, down 2 percent compared with the same period in 2012. We believe our investment portfolio mix provides an appropriate balance of income stability and growth with capital appreciation potential.

Highlights of Our Strategy and Supporting Initiatives

Management has worked to identify a strategy that can lead to long-term success, with concurrence by the board of directors. Our strategy is intended to position us to compete successfully in the markets we have targeted while appropriately managing risk. Further description of our long-term, proven strategy can be found in our 2012 Annual Report on Form 10-K, Item 1, Our Business and Our Strategy, Page 3. We believe successful implementation of initiatives that support our strategy, summarized below, will help us better serve our agent customers and reduce variability in our financial results while we also grow earnings and book value over the long term, successfully navigating challenging economic, market or industry pricing cycles.

• Improve insurance profitability - Implementation of these initiatives is intended to enhance underwriting expertise and knowledge, thereby increasing our ability to manage our business while also gaining efficiency. Additional information and more focused action on underperforming product lines, plus expanding pricing capabilities through the use of technology and analytics, can lead to better profit margins. Improved internal processes with additional performance metrics can help us be more efficient and effective. These initiatives also support the ability of the independent agencies that represent us to grow profitably by allowing them to serve clients faster and to more efficiently manage agency expenses.

• Drive premium growth - Implementation of these initiatives is intended to further penetrate each market we serve through our independent agency network. Strategies aimed at specific market opportunities, along with service enhancements, can help our agents grow and increase our share of their business. Diversified growth also may reduce variability of losses from weather-related catastrophes.

Below we discuss key initiatives supporting these strategies, along with an assessment of our progress.

Improve Insurance Profitability

The main initiatives to improve our insurance profitability include:

• Enhance underwriting expertise and knowledge - We continue efforts to increase our use of information and to develop our skills for improved underwriting performance, such as expanding our pricing capabilities by using predictive analytics. Expanded capabilities include streamlining and optimizing data to improve accuracy, timeliness and ease of use. We also continue to develop additional business data and tools to support more accurate underwriting, including more granular pricing, by further developing our data warehouse used in our property casualty and life insurance operations.

Work continues on initiatives to more profitably underwrite property coverages, including more staff specialization, increased insured property inspections to provide enhanced underwriting knowledge and greater use of deductibles or other policy terms and conditions as policies renew. Progress on initiatives during the first six months of 2013 included conducting over 30,000 inspections or applying loss control activities on a significant number of commercial properties and homes across several states, allowing us to increase our emphasis on roof conditions or other policy underwriting attributes. As expected, the inspections are resulting in underwriting or pricing actions – in some cases minor and in some cases significant – for a substantial portion of the inspected properties. We are also increasing our use of higher minimum loss deductible amounts and per-building deductibles for commercial risks, along with more use of wind and hail deductibles in areas subject to severe convective storm activity. We are expanding use of actual cash value coverage for older roofs and cosmetic damage exclusions for certain roof types. We expect these actions, along with others such as the use of hail-mapping technology to identify possible roof damage from prior hailstorms, to improve underwriting profitability over time for our property-related lines of business.

Similar initiatives are underway to more profitably underwrite our commercial auto line of business. A multi-department, multi-disciplinary taskforce has been working to determine ways to improve profitability, similar to the approach we used to improve workers' compensation results. Initiatives in process during the first half of 2013 included continuing education for underwriters and field marketing representatives and more

Cincinnati Financial Corporation Second-Quarter 2013 10-Q

Page 31

focus on factors to improve pricing precision. These factors include proper classification of insured commercial autos, information about their cost-new, and improvements in the collection and use of accurate commercial vehicle identification numbers. We also are carefully managing limits when we provide umbrella liability coverage over commercial auto liability coverage.

We continue to refine our pricing precision during 2013, including use in additional states of predictive modeling tools for small business policies written through our CinciPak^TM product. Progress during the first six months of 2013 included implementing CinciPak in four additional states, bringing the total number of states where that product was available to 12 at midyear. We are also making progress with predictive modeling for dwelling fire policies and development of a by-peril rating plan for homeowners. We plan to introduce both in select states in 2014. By-peril rating will improve pricing precision by separately pricing for the risk of losses from distinct perils, such as wind versus fire.

• Improve internal processes - Improved processes support our strategic goals, reducing internal costs and allowing us to focus more resources on providing agency services. Related efforts include additional streamlining of processes to issue qualified personal lines or small commercial lines business without intervention by an underwriter. Progress during the first six months of 2013 included expanding streamlined processing of small commercial property and general liability policies to additional states, and it is now available in 36 states. Audits of policies processed without an underwriter continue to indicate that those automated policies are being underwritten appropriately and issued as intended.

We measure the overall success of our strategy to improve property casualty insurance profitability primarily through our GAAP combined ratio, which we believe can be consistently within the range of 95 percent to 100 percent for any five-year period. We also compare our statutory combined ratio to the industry average to gauge our progress, as discussed in the Performance Drivers section above.

In addition, we expect these initiatives to contribute to our rank as the No. 1 or No. 2 carrier based on premium volume in agencies that have represented us for at least five years. In 2012, we again earned that rank in nearly 75 percent of the agencies that have represented Cincinnati Insurance for more than five years, based on 2012 premiums. We are working to increase the percentage of agencies where we achieve that rank.

Drive Premium Growth

Primary initiatives to drive premium growth include:

• Expansion of our marketing and service capabilities - We continue to enhance our generalist approach to allow our appointed agencies to better compete in the marketplace by providing services an agent's clients want and need. Expansion initiatives include ongoing development of targeted marketing programs, adding field marketing representatives for additional agency support in selected areas and piloting additional services to select agencies to develop our new customer care center for small commercial business policies. Progress during the first six months of 2013 included launching two of the four additional target market programs we plan to offer by the end of the year. We also completed the initial implementation in selected markets of a small consumer advertising campaign to test this mode of support for our independent agents. We expanded our excess and surplus lines field underwriting presence by adding four field marketing representatives. In addition, we added two field marketing representatives to support agencies in new marketing territories for commercial lines operations.

• New agency appointments - We continue to appoint new agencies to develop additional points of distribution, focusing on areas where our market share is less than 1 percent while also considering economic and catastrophe risk factors. In 2013, we initially targeted approximately 65 appointments of independent agencies and now intend to exceed that target by approximately 15 appointments. During the first six months of 2013, we appointed 63 new agencies that write in aggregate approximately $1.1 billion in property casualty premiums annually with various insurance carriers for an average of approximately $17 million per agency. As of June 30, 2013, a total of 1,437 agency relationships market our standard market insurance products from 1,804 reporting locations.

Cincinnati Financial Corporation Second-Quarter 2013 10-Q

Page 32

We seek to build a close, long-term relationship with each agency we appoint. We carefully evaluate the marketing reach of each new appointment to ensure the territory can support both current and new agencies. Our 130 commercial lines field marketing territories are staffed by marketing representatives averaging 20 years of industry experience and 10 years as a Cincinnati Insurance field marketing representative. Teams of field associates for each territory work together, providing local expertise with support from headquarters associates. This agent-centered business model helps us better understand the accounts we underwrite and creates marketing advantages for our agents. Unique Cincinnati-style service supports our agents as they grow their business and attract more clients in their communities. As a result, we generally have earned a 10 percent share of an agency's business within 10 years of its appointment.

We measure the overall success of our strategy to drive premium growth primarily through changes in net written premiums, as discussed in the Performance Drivers section above. In addition to tracking our progress toward our year-end 2015 annual direct written premiums target of $5 billion, we believe we can grow faster than the industry average over any five-year period.

Financial Strength

An important part of our long-term strategy is financial strength, which is described in our 2012 Annual Report on Form 10-K, Item 1, Our Business and Our Strategy, Financial Strength, Page 5. One aspect of our financial strength is prudent use of reinsurance to help manage financial performance variability due to catastrophe loss experience. A description of how we use reinsurance is included in our 2012 Annual Report on Form 10-K, Item 7, Liquidity and Capital Resources, 2013 Reinsurance Programs, Page 95. Another aspect is our investment portfolios, which remain well-diversified as discussed in this quarterly report Item 3, Quantitative and Qualitative Disclosures about Market Risk. We continue to maintain strong parent-company liquidity and financial strength that increases our flexibility through all periods to maintain our cash dividend and to continue to invest in and expand our insurance operations. At June 30, 2013, we held $1.369 billion of our cash and invested assets at the parent company level, of which $1.196 billion, or 87.4 percent, was invested in common stocks, and $50 million, or 3.7 percent, was cash or cash equivalents. Our debt-to-total-capital ratio at 13.6 percent remains well below our target limit. Another important indicator of financial strength is our ratio of property casualty net written premiums to statutory surplus, which was 0.9‑to‑1 for the 12 months ended June 30, 2013, unchanged from year-end 2012.

Our financial strength ratings assigned by independent ratings firms also are important. In addition to rating our parent company's senior debt, four firms award insurer financial strength ratings to one or more of our insurance subsidiary companies based on their quantitative and qualitative analyses. These ratings primarily assess an insurer's ability to meet financial obligations to policyholders and do not necessarily address all of the matters that may be important to investors. Ratings may be subject to revision or withdrawal at any time by the rating agency, and each rating should be evaluated independently of any other rating.

As of July 24, 2013, our insurer financial strength ratings were:

All of our insurance subsidiaries continue to be highly rated.

On April 30, 2013, Moody's Investors Service affirmed our insurance financial strength ratings that it had assigned in September 2008, revising its outlook to stable from negative. Moody's reported that its rating is based on our entrenched regional franchise from our strong relationships with agents, our focus on small- and middle-market commercial lines risks and our good risk-adjusted capital position. Moody's said other strengths include consistent reserve strength with strong financial flexibility and substantial holding company liquidity. Moody's added that our strengths are tempered by factors such as exposure to Midwest weather-related catastrophes, potential investment volatility due to a sizeable position in common equities relative to peers and competition from well-capitalized nationwide commercial lines carriers.

On May 1, 2013, Fitch Ratings affirmed our ratings that it had assigned in September 2010, continuing its stable outlook. Fitch noted that ratings strengths include conservative capitalization, our sizeable holding company cash and marketable securities position and a moderate financial leverage ratio. Fitch noted our reserve adequacy and benefits from our implementation of underwriting and pricing actions. Fitch said its rating could be unfavorably affected by a combined ratio exceeding 105 percent on a sustained basis or by deterioration in current balance sheet strengths.

On June 24, 2013, Standard & Poor's Ratings Services affirmed our ratings that it had assigned in August 2011, continuing its stable outlook. S&P said its rating reflected our strong competitive position and extremely strong capital and earnings, and also noted our geographic diversity and diversification benefits from our life insurance business. S&P stated that our risk position is moderate despite potential earnings volatility stemming from exposure to weather-related catastrophe losses, and that its rating could be unfavorably affected if capital adequacy deteriorated for a prolonged period of time or if earnings weakened substantially.

Our consolidated property casualty insurance operations generated underwriting profits of $34 million and $112 million for the three and six months ended June 30, 2013, compared with underwriting losses of $77 million and $68 million for the three and six months ended June 30, 2012. The primary driver of the improved underwriting results was lower losses from natural catastrophes. Current accident year loss experience before catastrophes also improved, along with related ratios, reflecting higher pricing in addition to the effects of our initiatives to improve pricing precision and loss experience related to claims and loss control practices. Prior accident year loss experience before catastrophes during the second quarter of 2013 was slightly more favorable, compared with the second quarter of 2012, and the first six months of 2013 was less favorable than the same period in 2012. The less favorable six-month 2013 experience was primarily due to re-estimates of losses incurred but not reported (IBNR). Details of property casualty insurance results are discussed below, including our commercial lines, personal lines and excess and surplus lines segments.

We measure and analyze property casualty underwriting results primarily by the combined ratio and its component ratios. The GAAP-basis combined ratio is the percentage of incurred losses plus all expenses per each earned premium dollar – the lower the ratio, the better the performance. An underwriting profit results when the combined

Cincinnati Financial Corporation Second-Quarter 2013 10-Q

Page 35

ratio is below 100 percent. A combined ratio above 100 percent indicates that an insurance company’s losses and expenses exceeded premiums.

Our consolidated property casualty combined ratio for the second quarter improved 13.1 percentage points, and for the first six months of 2013 it improved 10.5 points, both compared with the same periods of 2012. In addition to catastrophe losses that were 9.5 and 9.8 percentage points lower, the loss and loss expenses ratios before catastrophe losses were 4.0 and 1.3 points lower, together accounting for most of the improvement.

The combined ratio can be affected significantly by natural catastrophe losses and other large losses as discussed in detail below. The combined ratio can also be affected by updated estimates of loss and loss expense reserves established for claims that occurred in prior periods, referred to as prior accident years. Net favorable development on prior accident year reserves, including reserves for catastrophe losses, lowered the combined ratio by 5.6 percentage points in the first six months of 2013, compared with 12.4 percentage points in the same period of 2012. Net favorable development is discussed in further detail in results of operations by property casualty insurance segment.

The ratio for current accident year loss and loss expenses before catastrophe losses also improved. The 61.5 percent ratio for the first six months of 2013 improved 7.3 percentage points compared with the 68.8 percent accident year 2012 ratio measured as of June 30, 2012, largely reflecting recent-year initiatives to improve pricing precision and loss experience related to claims and loss control practices, along with improving market conditions. Improving market conditions included overall higher pricing, somewhat offset by normal loss cost inflation. Higher new large losses incurred, shown on the table below, Consolidated Property Casualty Insurance Losses by Size, increased the 2013 ratio by 0.3 percentage points, partially offsetting overall improvement in the ratio for current accident year loss and loss expenses before catastrophe losses.

The underwriting expense ratio rose for the second quarter and first six months of 2013, compared with the same periods of 2012, primarily due to higher commissions.

The trends in net written premiums and earned premiums summarized in the table above largely reflect the effects of our premium growth strategies and better pricing.

Consolidated property casualty net written premiums for the three and six months ended June 30, 2013, grew $81 million and $208 million compared with the same periods of 2012. Each of our property casualty segments grew during the second quarter and first six months of 2013. Our premium growth initiatives from prior years continue to favorably affect current year growth, particularly as newer agency relationships mature over time. We discuss current initiatives in the Highlights of Our Strategy and Supporting Initiatives section of this quarterly report. The main drivers of trends for 2013 are discussed by segment below in Results of Operations.

Cincinnati Financial Corporation Second-Quarter 2013 10-Q

Page 36

Consolidated property casualty agency new business written premiums for the three and six months ended June 30, 2013, increased $8 million and $35 million compared with the same periods of 2012. We continued to experience new business growth related to initiatives for geographic expansion into new and underserved areas. New agency appointments during 2012 and 2013 produced an $18 million increase in standard lines new business for the first six months of 2013 compared with the same period in 2012. As we appoint new agencies that choose to move accounts to us, we report these accounts as new business. While this business is new to us, in many cases it is not new to the agent. We believe these seasoned accounts tend to be priced more accurately than business that may be less familiar to our agent upon obtaining it from a competing agent.

Other written premiums include premiums ceded to our reinsurers as part of our reinsurance program. Ceded premiums reduced net written premium growth by $7 million and $11 million for the three and six months ended June 30, 2013, compared with the same periods of 2012.

Catastrophe losses typically have a meaningful effect on property casualty results and can vary significantly from period to period. Losses from natural catastrophes contributed 8.3 and 4.8 percentage points to the combined ratio in the second quarter and first six months of 2013, compared with 17.8 and 14.6 percentage points in the same periods of 2012. Some of those losses were applicable to loss deductible provisions of collateralized reinsurance funded through catastrophe bonds. Aggregate losses for the first six months of 2013, for the 75 counties included in the severe convective storm portion of that catastrophe reinsurance coverage, were approximately $2 million in excess of the $5 million per-event deductible. If aggregate losses after deductibles exceed $125 million during 2013, we can recover the excess through funds that collateralize the catastrophe bonds. The following table shows catastrophe losses and loss expenses incurred, net of reinsurance, as well as the effect of loss development on prior period catastrophe events. We individually list declared catastrophe events for which our incurred losses reached or exceeded $5 million.

We believe the inherent variability of aggregate loss experience for our portfolio of larger policies is greater than that of our portfolio of smaller policies, and we continue to monitor the variability in addition to general inflationary trends in loss costs. Our analysis continues to indicate no unexpected concentration of these large losses and case reserve increases by risk category, geographic region, policy inception, agency or field marketing territory. The second-quarter 2013 property casualty total large losses incurred of $169 million, net of reinsurance, were slightly lower than the $171 million quarterly average during 2012 and were higher than the $164 million for the second quarter of 2012. The ratio for these large losses and case reserve increases was 1.4 percentage points lower compared with last year’s second quarter, with new losses down 2.9 points and case reserve development up 1.5 points. Second-quarter large losses added to the ratio for total large losses incurred for the first six months of 2013, which also included a first-quarter 2013 ratio that was 0.4 points higher than the first quarter of 2012. We believe results for the three-month and six-month periods largely reflected normal fluctuations in loss patterns and normal variability in large case reserves for claims above $250,000. Losses by size are discussed in further detail in results of operations by property casualty insurance segment.

Overview

Performance highlights for the commercial lines segment include:

• Premiums – Commercial lines earned premiums and net written premiums rose during the second quarter and first six months of 2013 primarily due to higher renewal premiums that continued to reflect improved pricing. Higher new business written premiums also contributed to premium growth, reflecting better pricing as well as our premium growth initiatives. The premiums table below analyzes the primary components of earned premiums. We continue to use predictive analytics tools to improve pricing precision while also leveraging our local relationships with agents through the efforts of our teams that work closely with them. We seek to maintain appropriate pricing discipline for both new and renewal business as our agents and underwriters assess account quality to make careful decisions on a case-by-case basis whether to write or renew a policy.

Agency renewal written premiums rose 9 percent and 10 percent for the second quarter and first half of 2013, reflecting higher pricing and improving economic conditions. We measure average changes in commercial lines renewal pricing as the rate of change in renewal premium for the new policy period compared with the premium for the expiring policy period, assuming no change in the level of insured exposures or policy coverage between those periods for respective policies. During the second quarter of 2013, our standard commercial lines policies averaged estimated price increases in a mid-single-digit range, essentially in line with average increases in the first quarter. Our average commercial lines pricing change includes the flat pricing effect of certain coverages within package policies written for a three-year term that were in force but did not expire during the period being measured. Therefore, the average commercial lines pricing change we report reflects a blend of

Page 40

three‑year policies that did not expire and other policies that did expire during the measurement period. For only those commercial lines policies that did expire and were subsequently renewed during the second quarter of 2013, we estimate that the average price increase was again near the upper end of the mid-single-digit range, with smaller commercial property policies again experiencing average renewal price increases at a low-double-digit rate.

Renewal premiums for our commercial casualty and workers’ compensation lines include the result of policy audits that adjust initial premium amounts based on differences between estimated and actual sales or payroll related to a specific policy. Net written premiums from audits during the second quarter and first six months of 2013 netted a positive $11 million and $21 million, respectively. Audits contributed $2 million to the $52 million net increase in net written premiums for the second quarter of 2013 and $7 million to the $154 million net increase in net written premiums for the first six months of 2013, both compared with the same periods a year ago. The $118 million increase in earned premiums during the first six months of 2013, compared with 2012, included a decrease from audit premiums of less than $1 million.

New business written premiums for commercial lines increased 10 percent and 19 percent during the second quarter and first six months of 2013, compared with the same periods last year. In 24 of the 39 states where we offer standard market commercial lines policies, new business written premiums grew at a double-digit rate or higher for the first half of 2013 compared with the same period of 2012.

Other written premiums – which primarily include premiums ceded to our reinsurers as part of our reinsurance program – included ceded commercial lines premiums for the second quarter of 2013 that totaled $2 million more than the second quarter of 2012. For the first six months of 2013, ceded premiums totaled $3 million more than the same period of 2012. Other written premiums also included a less favorable adjustment for the second quarter and a more favorable adjustment for the first six months of 2013, compared with the same periods last year, for estimated direct written premiums of policies in effect but not yet processed. The adjustments had an immaterial effect on earned premiums.

• Combined ratio – The commercial lines combined ratio improved for the three and six months ended June 30, 2013, compared with the same periods of 2012, primarily due to weather-related natural catastrophe losses that were 8.1 and 7.4 percentage points lower.

Catastrophe losses accounted for 7.1 and 3.8 percentage points of the combined ratio for the three and six months ended June 30, 2013, compared with 15.2 and 11.2 percentage points for the same periods last year. The 10-year annual average catastrophe loss impact through 2012 for the commercial lines segment is 4.3 percentage points, and the five-year annual average is 5.9 percentage points.

The ratio for current accident year loss and loss expenses before catastrophe losses improved. The 61.4 percent ratio for the first six months of 2013 improved 6.1 percentage points compared with the 67.5 percent accident year 2012 ratio measured as of June 30, 2012, reflecting both our profit-improvement initiatives and improving market conditions. Higher new large losses incurred, shown in the table below, increased the 2013 ratio 2.0 percentage points more than in 2012 and partially offset other effects that improved the ratio. We believe the net improvement is largely due to initiatives to improve pricing precision and loss experience related to claims and loss control practices, in addition to higher prices that were somewhat offset by normal loss cost inflation or inherent variability of large losses.

The net effect of reserve development on prior accident years during the second quarter and first six months of 2013 was favorable for commercial lines overall by $66 million and $78 million compared with $72 million and $162 million for the same periods in 2012. For the six months ended June 30, 2013, favorable reserve development on prior accident years in the commercial casualty line of business represented 71 percent of the commercial lines favorable development. Workers' compensation accounted for 29 percent of the favorable development, with the remaining commercial lines of business netting to less than 1 percent. The favorable reserve development recognized during the first six months of 2013 for commercial lines included approximately 42 percent for accident year 2012 and approximately 27 percent for accident year 2011, and was primarily due to lower than anticipated loss emergence on known claims. Reserve estimates are inherently uncertain as described in our 2012 Annual Report on Form 10-K, Item 7, Critical Accounting Estimates, Property Casualty Insurance Loss and Loss Expense Reserves, Page 43.

The commercial lines underwriting expense ratio decreased for the second quarter and first half of 2013, compared with the same periods of 2012, primarily due to higher earned premiums.

Underwriting results and related measures for the combined ratio are summarized in the first table of Commercial Lines Insurance Results of Operations. The tables and discussion below provide additional details for certain primary drivers of underwriting results.

Total loss ratio	54.9		%	59.6		%	(4.7	)	51.2		%	54.0		%	(2.8	)

We continue to monitor new losses and case reserve increases greater than $250,000 for trends in factors such as initial reserve levels, loss cost inflation and claim settlement expenses. Our analysis continues to indicate no unexpected concentration of these large losses and case reserve increases by risk category, geographic region, policy inception, agency or field marketing territory. The second-quarter 2013 commercial lines total large losses incurred of $146 million, net of reinsurance, were somewhat higher than the $141 million quarterly average during 2012. They were also higher than the $124 million total large losses incurred for the second quarter of 2012, primarily due to higher 2013 commercial fire losses. The ratio for these large losses and case reserve increases was 1.6 percentage points higher compared with last year’s second quarter as the increase in total large losses incurred offset higher earned premiums. Second-quarter large losses added to the ratio for total large losses incurred for the first six months of 2013, which also included a higher number of claims and higher incurred losses for commercial fires during the first quarter. We believe results for the three-month period largely reflected normal fluctuations in loss patterns and normal variability in large case reserves for claims above $250,000.

Commercial Lines of Business Analysis

Approximately 95 percent of our commercial lines premiums relate to accounts with coverages from more than one of our business lines. As a result, we believe that our commercial lines business is best measured and evaluated on a segment basis. However, we provide line of business data to summarize premium and loss trends separately for each line. The ratios shown in the table below are components of loss and loss expenses as a percentage of earned premiums.

As discussed above, the loss and loss expenses ratio component of the combined ratio is an important measure of underwriting profit and performance. Catastrophe losses are volatile and can distort short-term profitability trends, particularly for certain lines of business. Development of loss and loss expense reserves on prior accident years can also distort trends in measures of profitability for recently written business. To illustrate these effects, we separate their impact on the ratios shown in the table above. For the three and six months ended June 30, 2013, the commercial lines of business with the most significant profitability challenge were surety and executive risk and specialty packages. Our first-half 2013 surety and executive risk results included unfavorable development on prior accident year reserves for director and officer liability related to financial institutions. As discussed in our 2012 Annual Report on Form 10-K, Item 7, Commercial Lines Insurance Results of Operations, Page 66, we have taken steps to actively manage the potentially high risk of writing director and officer liability. On 10-K Page 65, we noted that specialty package results were expected to improve over time due to efforts to improve pricing precision in addition to various initiatives related to the property coverage portion of this line of business. Those underwriting actions, and the introduction of CinciPak – a new program designed to replace many of our specialty products, are partly responsible for a 29 percent reduction in specialty packages new business written premiums for the first six months of 2013, compared with a 9 percent increase for the same period of 2012.

Overview

Performance highlights for the personal lines segment include:

• Premiums – Personal lines earned premiums and net written premiums for the second quarter and first half of 2013 continued to grow primarily due to higher renewal premiums. The increase reflected improved pricing and a steady, high level of policy retention. Higher new business written premiums also contributed to premium growth, reflecting better pricing as well as our premium growth initiatives. The premiums table below analyzes the primary components of earned premiums.

Agency renewal written premiums increased 11 percent for both the second quarter and first six months of 2013 because of rate increases in recent years, ongoing high levels of policy retention, premium growth initiatives and a higher level of insured exposures. Rate increases that we began implementing in October 2012 for the homeowner line of business have averaged approximately 9 percent, with some individual policy rate increases lower or higher based on risk characteristics of the insured exposure.

In the first half of the year, we began implementing our 2013 rate changes for our personal auto line of business in the majority of the 30 states where we market personal auto policies. The average rate change was an increase in the low-single-digit range, with some individual policies experiencing lower or higher rates based on enhanced pricing precision enabled by predictive models. Rate changes for personal auto beginning in late 2010 and 2011 also represented an average rate increase in the low-single-digit range.

Page 45

Personal lines new business written premiums continued to grow during the first six months of 2013, up 9 percent compared with the first half of 2012, with growth slowing during the second quarter as expected due to underwriting actions such as expanded use of actual cash value loss settlement for older roofs. We continue to believe we are successful in attracting more of our agents’ preferred business when it is priced more accurately based on insured exposure.

Other written premiums – which primarily include premiums ceded to our reinsurers as part of our reinsurance program – decreased net written premium growth by $2 million and $4 million more for the three and six months ended June 30, 2013, than for the same periods of 2012.

We continue to implement strategies discussed in our 2012 Annual Report on Form 10-K, Item 1, Strategic Initiatives, Page 10, to enhance our responsiveness to marketplace changes and to help achieve our long-term objectives for personal lines growth and profitability. These strategies include several initiatives to more profitably underwrite property coverages.

• Combined ratio – The personal lines combined ratio improved for the three and six months ended June 30, 2013, compared with the same periods of 2012, primarily due to weather-related catastrophe losses that were 14.0 and 16.9 percentage points lower.

Catastrophe losses accounted for 12.6 and 8.1 percentage points of the combined ratio for the three and six months ended June 30, 2013, compared with 26.6 and 25.0 percentage points for the same periods last year. The 10-year annual average catastrophe loss ratio through 2012 for the personal lines segment was 11.4 percentage points, and the five-year annual average is 15.6 percentage points.

The ratio for current accident year loss and loss expenses before catastrophe losses for the six months ended June 30, 2013, also improved compared with the same 2012 period. The 60.9 percent ratio for the first six months of 2013 improved 10.7 percentage points compared with the 71.6 percent accident year 2012 ratio measured as of June 30, 2012. This improvement largely reflected higher rates in addition to recent-year initiatives to improve pricing precision and risk selection. Lower new large losses incurred, shown in the table below, contributed 4.8 percentage points to the 2013 ratio improvement.

In addition to the rate increases discussed above, we continue to refine our pricing to better match premiums to the risk of loss on individual policies. The results of improved pricing per risk and broad-based rate increases are expected to help position the combined ratio at a profitable level over the long term. In addition, greater geographic diversification is expected over time to reduce the volatility of homeowner loss ratios attributable to weather-related catastrophe losses.

Personal lines reserve development on prior accident years continued to emerge favorably during the second quarter and first six months of 2013. Favorable reserve development was $17 million lower for the first six months of 2013 compared with the same period of 2012, with catastrophe loss development contributing $10 million of the decrease. Approximately half of the $22 million of favorable reserve development on prior accident years recognized during the first six months of 2013 occurred in the homeowner line of business and roughly one-quarter occurred in the other personal line of business, reflecting lower than anticipated loss emergence on known claims. Approximately three-quarters of the personal lines favorable reserve development recognized during the first six months of 2013 was for accident year 2012 and approximately one-quarter was

for accident year 2011, with all other accident years netting to less than 5 percent. Reserve estimates are inherently uncertain as described in our 2012 Annual Report on Form 10-K, Item 7, Property Casualty Insurance Loss and Loss Expense Reserves, Page 43.

The underwriting expense ratio rose for the second quarter and first six months of 2013 compared with the same periods of 2012, primarily due to higher commissions.

We continue to monitor new losses and case reserve increases greater than $250,000 for trends in factors such as initial reserve levels, loss cost inflation and claim settlement expenses. Our analysis continues to indicate no unexpected concentration of these large losses and case reserve increases by risk category, geographic region, policy inception, agency or field marketing territory. In the second quarter of 2013, the personal lines total ratio for these losses and case reserve increases, net of reinsurance, was 9.7 percentage points lower compared with last year’s second quarter, reflecting a lower number of homeowner fire claims and incurred losses. Second-quarter large losses added to the ratio for total large losses incurred for the first six months of 2013, which also included a higher number of claims and incurred losses for our personal auto line of business during the first quarter. We believe results for the three-month period largely reflected normal fluctuations in loss patterns and normal variability in large case reserves for claims above $250,000.

Personal Lines of Business Analysis

We prefer to write personal lines coverages on an account basis to include both auto and homeowner coverages as well as coverages from the other personal business line. As a result, we believe that our personal lines business is best measured and evaluated on a segment basis. However, we provide the line of business data to summarize premium and loss trends separately for each line. The ratios shown in the table below are components of loss and loss expenses as a percentage of earned premiums.

Total loss and loss expenses ratio	38.1		%	79.6		%		46.8		%	64.8		%

As discussed above, the loss and loss expenses ratio component of the combined ratio is an important measure of underwriting profit and performance. Catastrophe losses are volatile and can distort short-term profitability trends, particularly for certain lines of business. Development of loss and loss expense reserves on prior accident years can also distort trends in measures of profitability for recently written business. To illustrate these effects, we separate their impact on the ratios shown in the table above. For the three and six months ended June 30, 2013, the personal line of business with the most significant profitability challenge was personal auto, in part due to large losses as discussed above. As discussed in Personal Lines Insurance Results of Operations, Overview, we continue actions to improve pricing per risk and overall rates, which are expected to improve future profitability. The higher personal auto ratios for 2013 were driven by higher estimates for losses incurred but not reported, as the ratio for case incurred losses improved, compared with the same periods of 2012.

Overview

Performance highlights for the excess and surplus lines segment include:

• Premiums – Excess and surplus lines earned premiums and net written premiums continued to grow during the second quarter and first six months of 2013. Growth in renewal written premiums contributed most of the increase.

Renewal written premiums rose 37 percent and 29 percent for the second quarter and first six months of 2013, compared with the same periods of 2012, reflecting the opportunity to renew many accounts for the first time as well as higher renewal pricing. Renewal pricing increases estimated for our excess and surplus lines policies on average continued in a low-double-digit range. We measure average changes in excess and surplus lines renewal pricing as the rate of change in renewal premium for the new policy period compared with the premium for the expiring policy period, assuming no change in the level of insured exposures or policy coverage between those periods for respective policies.

New business written premiums declined for the second quarter and first six months of 2013, compared with the same periods of 2012, primarily because we wrote fewer new large-premium accounts. Some of what we report as new business came from accounts that were not new to our agents. We believe our agents’ seasoned accounts tend to be priced more accurately than business that may be less familiar to them.

• Combined ratio – The excess and surplus lines combined ratio improved for the second quarter and first six months of 2013 by 12.0 and 13.7 percentage points compared with the same periods of 2012, primarily due to lower current accident year loss and loss expenses before catastrophe losses, which reflected higher pricing and typical variability from new losses incurred of $250,000 or more.

The 69.6 percent ratio for current accident year loss and loss expenses before catastrophe losses for the first six months of 2013 improved 6.8 percentage points compared with the 76.4 percent accident year 2012 ratio measured as of June 30, 2012. This decrease reflects higher pricing and new losses incurred of $250,000 or more that improved by 3.2 points for the first six months of 2013, compared with 2012, as shown in the Excess and Surplus Lines Insurance Losses by Size table below.

Catastrophe losses accounted for 1.9 and 1.2 percentage points of the combined ratio for the three and six months ended June 30, 2013, compared with 3.5 percentage points for both of the same periods of 2012.

Excess and surplus lines net favorable reserve development on prior accident years as a ratio to earned premiums was not material for the second quarter and was 4.1 percentage points for the first six months of 2013, compared with 1.0 and 0.9 percentage points of unfavorable reserve development for the same periods of 2012. Reserve estimates are inherently uncertain as described in our 2012 Annual Report on Form 10-K, Item 7, Property Casualty Insurance Loss and Loss Expense Reserves, Page 43.

The underwriting expense ratio for the second quarter and first six months of 2013 was essentially flat compared with the same periods of 2012.

Our analysis continues to indicate no unexpected concentration of these large losses and case reserve increases by risk category, geographic region, policy inception, agency or field marketing territory. In the second quarter of 2013, the excess and surplus line total ratio for these losses and case reserve increases, net of reinsurance, was 1.2 percentage points higher compared with last year’s second quarter, largely due to a higher frequency of large losses. The 22.6 percent ratio for total large losses incurred for the first six months of 2013 was lower than the full-year 2012 ratio of 25.5 percent. Second-quarter large losses added to the ratio for total large losses incurred for the first six months of 2013, which included a lower frequency of large losses during the first quarter. We believe results for the three-month period ended June 30, 2013, largely reflected normal fluctuations in loss patterns and normal variability in large case reserves for claims above $250,000.

Overview

Performance highlights for the life insurance segment include:

• Revenues – Revenues decreased for the three and six months ended June 30, 2013, primarily due to lower earned premiums from universal life insurance products. The unlocking of interest rate assumptions for our universal life contracts during the second quarter slowed the amortization of unearned front-end loads, reducing universal life earned premiums. For the comparable period in 2012, unlocking increased the amortization of unearned front-end loads, increasing universal life earned premiums.

Net in-force life insurance policy face amounts increased to $46.637 billion at June 30, 2013, from $45.126 billion at year-end 2012.

Fixed annuity deposits received for the three and six months ended June 30, 2013, were $10 million and $21 million compared with $13 million and $30 million for the same periods of 2012. Fixed annuity deposits have a minimal impact to earned premiums because deposits received are initially recorded as liabilities. Profit is earned over time by way of interest rate spreads. We do not write variable or equity annuities and are currently de-emphasizing fixed annuity sales due to the low interest rate environment.

Net earned premiums	$	44	$	51	(14	)	$	86	$	92	(7	)

• Profitability – Our life insurance segment typically reports a small profit or loss on a GAAP basis because profits from investment income spreads are included in our investment segment results. We include only investment income credited to contract holders (including interest assumed in life insurance policy reserve calculations) in our life insurance segment results. A gain of $10 million for our life insurance segment in the first six months of 2013 compared with a loss of $1 million for the same period of 2012, primarily due to favorable mortality experience and decreased operating expenses.

Cincinnati Financial Corporation Second-Quarter 2013 10-Q

Page 52

Although we report most of our life insurance company investment income in our investments segment results, we recognize that assets under management, capital appreciation and investment income are integral to evaluation of the success of the life insurance segment because of the long duration of life products. On a basis that includes investment income and realized gains or losses from life insurance related invested assets, the life insurance company reported a net profit of $14 million and $28 million in the three and six months ended June 30, 2013, compared with a net profit of $11 million and $18 million for the same periods of 2012. The life insurance company portfolio had after-tax realized investment gains of $2 million for both the three and six months ended June 30, 2013, compared with after-tax realized investment gains of less than $1 million and $1 million for the same periods of 2012.

Life segment benefits and expenses consist principally of contract holders’ (policyholders’) benefits incurred related to traditional life and interest-sensitive products and operating expenses incurred, net of deferred acquisition costs. Total benefits increased modestly in the first six months of 2013. Through the first six months, mortality results were better than projected and were well within our pricing expectations.

Operating expenses for the first six months of 2013 decreased compared with the same period a year ago. Unlocking of interest rate assumptions, discussed in the revenues section above, also increased the amount of expenses deferred to future periods, reducing operating expenses for the second quarter and first six months of 2013. For the comparable periods in 2012, unlocking decreased the amount of expenses deferred to future periods, increasing operating expenses. During the first six months of 2012, operating expenses were further increased by an actuarial adjustment decreasing reinsurance-related expenses deferred to future periods.

The earnings effect of interest rate unlocking, for the respective first six-month periods of 2013 and 2012, is minimal because the change in earned premiums is essentially offset by the change in operating expenses.

INVESTMENT RESULTS OF OPERATIONS

Overview

The investments segment contributes investment income and realized gains and losses to results of operations. Investments traditionally are our primary source of pretax and after-tax profits.

Investment Income

Pretax investment income decreased 1 percent and 2 percent for the three and six months ended June 30, 2013, compared with the same periods of 2012. Interest income declined due to the continuing effects of the low interest rate environment. Higher dividend income for the three-month and six-month periods reflected rising dividend rates and net purchases of securities. Six-month 2013 dividend growth was partially offset by certain holdings that accelerated payments from the first quarter into the fourth quarter of 2012 in response to anticipated tax law changes. Average yields in the table below are based on the average invested asset and cash amounts indicated in the table, using fixed-maturity securities valued at amortized cost and all other securities at fair value. In our 2012 Annual Report on Form 10-K, Item 1, Investments Segment, Page 20, and Item 7, Investments Outlook, Page 83, we discussed our portfolio strategies. We discuss risks related to our investment income and our fixed-maturity and equity investment portfolios in this quarterly report Item 3, Quantitative and Qualitative Disclosures About Market Risk.

We continue to position our portfolio with consideration to both the challenges presented by the current low interest rate environment and the risks presented by potential future inflation. As bonds in our generally laddered portfolio mature or are called over the near term, we will be challenged to replace their current yield. Approximately 18.4 percent of our fixed-maturity investments mature during July 2013 through December 2015 with an average pretax yield-to-amortized cost of 4.6 percent, including 3.3 percent of the portfolio maturing during the last six months of 2013 and yielding 4.5 percent. While our bond portfolio more than covers our insurance reserve liabilities, we believe our diversified common stock portfolio of mainly blue chip, dividend-paying companies represents one of our best investment opportunities for the long term.

Net Realized Gains and Losses

We reported net realized investment gains of $14 million and $55 million in the three and six months ended June 30, 2013, as net gains from investment sales and bond calls were partially offset by other-than-temporary impairment (OTTI) charges. OTTI charges during the three-month and six-month periods ended June 30, 2013, were none and $2 million, respectively. We reported net realized investment gains of $6 million and $19 million for the three and six months ended June 30, 2012, as net gains from investment sales and bond calls offset OTTI charges.

Investment gains or losses are recognized upon the sales of investments or as otherwise required under GAAP. The timing of realized gains or losses from sales can have a material effect on results in any quarter. However, such gains or losses usually have little, if any, effect on total shareholders’ equity because most equity and fixed-maturity investments are carried at fair value, with the unrealized gain or loss included as a component of accumulated other comprehensive income. Accounting requirements for OTTI charges for the fixed-maturity portfolio are disclosed in our 2012 Annual Report on Form 10-K, Item 8, Note 1, Summary of Significant Accounting Policies, Page 115.

The total net realized investment gains for the first six months of 2013 included:

• $49 million in net gains from the sale of various common and preferred stock holdings.

• $4 million in net gains from fixed-maturity security sales and calls.

• $4 million in other net realized gains, including $1 million in gains from changes in fair value of securities with embedded derivatives.

• $2 million in OTTI charges to write down five fixed-maturity securities.

Of the 2,839 securities in the portfolio, no securities were trading below 70 percent of amortized cost at June 30, 2013. Our asset impairment committee regularly monitors the portfolio, including a quarterly review of the entire portfolio for potential OTTI charges. We believe that if the improving liquidity in the markets were to reverse or the economic recovery were to significantly stall, we could experience declines in portfolio values and possibly additional OTTI charges.

TAXES

We had $38 million and $101 million of income tax expense for the three and six months ended June 30, 2013, compared with an income tax benefit of $3 million for second quarter of 2012 and income tax expense of $23 million for the first six months of 2012. The effective tax rate for the three and six months ended June 30, 2013, was 25.7 percent and 27.7 percent compared with negative 10.3 percent and positive 16.3 percent for the same periods last year. The change in our effective tax rates was primarily due to changes in pretax income from underwriting results and realized investment gains and losses, with unchanged levels of permanent book-tax differences.

Historically, we have pursued a strategy of investing some portion of cash flow in tax-advantaged fixed-maturity and equity securities to minimize our overall tax liability and maximize after-tax earnings. See Tax-Exempt Fixed Maturities for further discussion on municipal bond purchases in our fixed-maturity investment portfolio. For our insurance subsidiaries, approximately 85 percent of income from tax-advantaged fixed-maturity investments is exempt from federal tax. Our noninsurance companies own an immaterial amount of tax-advantaged, fixed-maturity investments. For our insurance subsidiaries, the dividend received deduction, after the dividend proration of the 1986 Tax Reform Act, exempts approximately 60 percent of dividends from qualified equities from federal tax. For our noninsurance companies, the dividend received deduction exempts 70 percent of dividends from qualified

equities. Details about our effective tax rate are found in our 2012 Annual Report on Form 10-K, Item 8, Note 11, Income Taxes, Page 129, and in this quarterly report Item 1, Note 9 – Income Taxes.

LIQUIDITY AND CAPITAL RESOURCES

At June 30, 2013, shareholders’ equity was $5.699 billion compared with $5.453 billion at December 31, 2012. Total debt was $894 million at June 30, 2013, and at December 31, 2012. At June 30, 2013, cash and cash equivalents totaled $382 million compared with $487 million at December 31, 2012.

SOURCES OF LIQUIDITY

Subsidiary Dividends

Our lead insurance subsidiary declared dividends of $175 million to the parent company during the first six months of 2013, $25 million more than the same period of 2012. Another subsidiary, CFC Investment Company, declared and paid dividends of $25 million to the parent company during the first six months of 2013, in the first quarter, compared with none for full-year 2012. For the full-year 2012, subsidiary dividends declared totaled $300 million. State of Ohio regulatory requirements restrict the dividends our insurance subsidiary can pay. During 2013, total dividends that our insurance subsidiary could pay to our parent company without regulatory approval are approximately $391 million.

Investing Activities

Investment income is a source of liquidity for both the parent company and its insurance subsidiary. We continue to focus on portfolio strategies to balance near-term income generation and long-term book value growth.

Parent company obligations can be funded with income on investments held at the parent company level or through sales of securities in that portfolio, although we prefer to follow an investment philosophy seeking to compound cash flows over the long term. These sources of capital can help minimize subsidiary dividends to the parent company, protecting insurance subsidiary capital.

We own no European sovereign debt. Our European-based securities held at year-end 2012 are summarized by country in our 2012 Annual Report on Form 10-K, Item 7A, Qualitative and Quantitative Disclosures About Market Risk, Page 101. See our 2012 Annual Report on Form 10-K, Item 1, Investment Segment, Page 20, for a discussion of our historic investment strategy, portfolio allocation and quality.

Insurance Underwriting

Our property casualty and life insurance underwriting operations provide liquidity because we generally receive premiums before paying losses under the policies purchased with those premiums. After satisfying our cash requirements, we use excess cash flows for investment, increasing future investment income.

Historically, cash receipts from property casualty and life insurance premiums, along with investment income, have been more than sufficient to pay claims, operating expenses and dividends to the parent company.

The table below shows a summary of operating cash flow for property casualty insurance (direct method):

(Dollars in millions)	Three months ended June 30,								Six months ended June 30,
	2013			2012			Change %		2013			2012			Change %

Cincinnati Financial Corporation Second-Quarter 2013 10-Q

Page 57

Collected premiums for property casualty insurance rose $213 million during the first six months of 2013, compared with the same period in 2012. Loss and loss expenses paid decreased $45 million, primarily due to lower catastrophe losses paid. Commissions and other underwriting expenses paid rose $88 million, primarily due to higher commissions paid to agencies, reflecting the increase in collected premiums.

We discuss our future obligations for claims payments and for underwriting expenses in our 2012 Annual Report on Form 10-K, Item 7, Contractual Obligations, Page 86, and Other Commitments, also on Page 86.

Capital Resources

At June 30, 2013, our debt-to-total-capital ratio was 13.6 percent, with $790 million in long-term debt and $104 million in borrowing on our revolving short-term line of credit. There was no change in the amount of the $104 million short-term debt during the first six months of 2013. Based on our present capital requirements, we do not anticipate a material increase in debt levels during the remainder of 2013. As a result, we expect changes in our debt-to-total-capital ratio to continue to be largely a function of the contribution of unrealized investment gains or losses to shareholders’ equity.

We provide details of our three long-term notes in our 2012 Annual Report on Form 10-K, Item 8, Note 8, Long-Term Debt and Capital Lease Obligations, Page 127. None of the notes are encumbered by rating triggers.

Four independent ratings firms award insurer financial strength ratings to our property casualty insurance companies and three firms rate our life insurance company. Those firms made no changes to our debt ratings during the first six months of 2013. Our debt ratings are discussed in our 2012 Annual Report on Form 10-K, Item 7, Liquidity and Capital Resources, Additional Sources of Liquidity, Page 84.

Off-Balance Sheet Arrangements

We do not use any special-purpose financing vehicles or have any undisclosed off-balance sheet arrangements (as that term is defined in applicable SEC rules) that are reasonably likely to have a current or future material effect on the company’s financial condition, results of operation, liquidity, capital expenditures or capital resources. Similarly, the company holds no fair-value contracts for which a lack of marketplace quotations would necessitate the use of fair-value techniques.

USES OF LIQUIDITY

Our parent company and insurance subsidiary have contractual obligations and other commitments. In addition, one of our primary uses of cash is to enhance shareholder return.

Contractual Obligations

In our 2012 Annual Report on Form 10-K, Item 7, Contractual Obligations, Page 86, we estimated our future contractual obligations as of December 31, 2012. There have been no material changes to our estimates of future contractual obligations since our 2012 Annual Report on Form 10-K.

Other Commitments

In addition to our contractual obligations, we have other property casualty operational commitments.

• Commissions – Commissions paid were $395 million in the first six months of 2013. Commission payments generally track with written premiums, except for annual profit-sharing commissions typically paid during the first quarter of the year.

• Other underwriting expenses – Many of our underwriting expenses are not contractual obligations, but reflect the ongoing expenses of our business. Noncommission underwriting expenses paid were $239 million in the first six months of 2013.

• In addition to contractual obligations for hardware and software, we anticipate capitalizing approximately $4 million in spending for key technology initiatives in 2013. Capitalized development costs related to key technology initiatives were $2 million in the first six months of 2013. These activities are conducted at our discretion, and we have no material contractual obligations for activities planned as part of these projects.

Cincinnati Financial Corporation Second-Quarter 2013 10-Q

Page 58

We contributed $15 million to our qualified pension plan during the first six months of 2013. We do not anticipate further contributions to our qualified pension plan during the remainder of 2013.

Investing Activities

After fulfilling operating requirements, we invest cash flows from underwriting, investment and other corporate activities in fixed-maturity and equity securities on an ongoing basis to help achieve our portfolio objectives. We discuss our investment strategy and certain portfolio attributes in Item 3, Quantitative and Qualitative Disclosures about Market Risk.

Uses of Capital

Uses of cash to enhance shareholder return include dividends to shareholders. In February and April 2013, the board of directors declared a regular quarterly cash dividend of 40.75 cents per share for an indicated annual rate of $1.63 per share. During the first six months of 2013, we used $130 million to pay cash dividends to shareholders.

PROPERTY CASUALTY INSURANCE RESERVES

For the business lines in the commercial and personal lines insurance segments, and in total for the excess and surplus lines segment, the following table details gross reserves among case, IBNR and loss expense reserves, net of salvage and subrogation reserves. Reserving practices are discussed in our 2012 Annual Report on Form 10-K, Item 7, Property Casualty Insurance Loss and Loss Expense Obligations and Reserves, Page 88.

Total gross reserves at June 30, 2013, increased $50 million compared with December 31, 2012. Case reserves for losses increased $17 million while IBNR reserves increased by $54 million and total loss expense reserves decreased by $21 million.

LIFE POLICY AND INVESTMENT CONTRACT RESERVES

Gross life policy and investment contract reserves were $2.345 billion at June 30, 2013, compared with $2.295 billion at year-end 2012, reflecting continued growth in life insurance policies in force. We discuss our life insurance reserving practices in our 2012 Annual Report on Form 10-K, Item 7, Life Insurance Policyholder Obligations and Reserves, Page 94.

OTHER MATTERS

SIGNIFICANT ACCOUNTING POLICIES

Our significant accounting policies are discussed in our 2012 Annual Report on Form 10-K, Item 8, Note 1, Summary of Significant Accounting Policies, Page 112, and updated in this quarterly report Item 1, Note 1, Accounting Policies.

In conjunction with those discussions, in the Management’s Discussion and Analysis in the 2012 Annual Report on Form 10-K, management reviewed the estimates and assumptions used to develop reported amounts related to the most significant policies. Management discussed the development and selection of those accounting estimates with the audit committee of the board of directors.

Item 3.    Quantitative and Qualitative Disclosures About Market Risk

Our greatest exposure to market risk is through our investment portfolio. Market risk is the potential for a decrease in securities’ fair value resulting from broad yet uncontrollable forces such as: inflation, economic growth or recession, interest rates, world political conditions or other widespread unpredictable events. It is comprised of many individual risks that, when combined, create a macroeconomic impact.

Our view of potential risks and our sensitivity to such risks is discussed in our 2012 Annual Report on Form 10-K, Item 7a, Quantitative and Qualitative Disclosures about Market Risk, Page 100.

The fair value of our investment portfolio was $12.867 billion at June 30, 2013, up $401 million from year-end 2012, largely due to an increase in the common equities portfolio of $523 million.

At June 30, 2013, our consolidated investment portfolio included $6 million of assets for which values are based on prices or valuation techniques that require significant management judgment (Level 3 assets). This represented less than 1 percent of investment portfolio assets measured at fair value. See Item 1, Note 3, Fair Value Measurements, for additional discussion of our valuation techniques. We have generally obtained and evaluated two nonbinding quotes from brokers, then our investment professionals determine our best estimate of fair value. These investments include private placements, small issues and various thinly traded securities.

In addition to our investment portfolio, the total investments amount reported in our condensed consolidated balance sheets includes Other invested assets. Other invested assets included $35 million of life policy loans and liens plus $31 million of private equity investments at June 30, 2013.

FIXED-MATURITY INVESTMENTS

By maintaining a well-diversified fixed-maturity portfolio, we attempt to reduce overall risk. We invest new money in the bond market on a regular basis, targeting what we believe to be optimal risk-adjusted after-tax yields. Risk, in this context, includes interest rate, call, reinvestment rate, credit and liquidity risk. We do not make a concerted effort to alter duration on a portfolio basis in response to anticipated movements in interest rates. By regularly investing in the bond market, we build a broad, diversified portfolio that we believe mitigates the impact of adverse economic factors.

Cincinnati Financial Corporation Second-Quarter 2013 10-Q

Page 61

Our investment portfolio had no European sovereign debt holdings at June 30, 2013. On that date, we owned other European-based securities, primarily corporate bonds, totaling $488 million in fair value. We discussed our European-based holdings in our 2012 Annual Report on Form 10-K, Item 7a, Quantitative and Qualitative Disclosures about Market Risk, Page 101. The composition of our European-based holdings at June 30, 2013, did not materially change from the $504 million fair value total at year-end 2012.

In the first six months of 2013, the decrease in fair value of our fixed-maturity portfolio was due to a rise in interest rates. At June 30, 2013, our fixed-maturity portfolio was valued at 106.7 percent of its amortized cost, compared with 110.6 percent at December 31, 2012.

Credit ratings at June 30, 2013, compared with December 31, 2012, for the fixed-maturity and short-term portfolios were:

Our strategy is to buy and typically hold fixed-maturity investments to maturity, but we monitor credit profiles and fair value movements when determining holding periods for individual securities. With the exception of U.S. agency issues that include United States government and government sponsored enterprises, no individual issuer's securities accounted for more than 1.0 percent of the taxable fixed-maturity portfolio at June 30, 2013. Our investment-grade corporate bonds and commercial mortgage backed securities had an average rating of Baa1 by Moody’s or BBB+ by Standard & Poor’s and represented 87.8 percent of the taxable fixed-maturity portfolio’s fair value at June 30, 2013, compared with 88.2 percent at year-end 2012.

The heaviest concentration in our investment-grade corporate bond portfolio, based on fair value at June 30, 2013, is the financial-related sectors – including banking, financial services and insurance – representing 32.0 percent, compared with 31.2 percent at year-end 2012. We believe our weighting in financial-related sectors is below the average for the corporate bond market as a whole.

Most of the $319 million of securities issued by states, municipalities and political subdivisions included in our taxable fixed maturity portfolio at June 30, 2013, were Build America Bonds.

Our taxable fixed maturity portfolio at June 30, 2013, included $60 million of AAA rated commercial mortgage-backed securities.

TAX-EXEMPT FIXED MATURITIES

At June 30, 2013, we had $2.870 billion of tax-exempt fixed-maturity securities with an average rating of Aa2/AA by Moody’s and Standard & Poor’s. We traditionally have purchased municipal bonds focusing on general obligation and essential services issues, such as water, waste disposal or others. The portfolio is well diversified among approximately 1,000 municipal bond issuers. No single municipal issuer accounted for more than 0.7 percent of the tax-exempt fixed maturity portfolio at June 30, 2013. The following table shows our municipal bond holdings in our larger states:

Interest Rate Sensitivity Analysis

Because of our strong surplus, long-term investment horizon and ability to hold most fixed-maturity investments until maturity, we believe the company is adequately positioned if interest rates were to rise. Although the fair values of our existing holdings may suffer, a higher rate environment would provide the opportunity to invest cash flow in higher yielding securities, while reducing the likelihood of untimely redemptions of currently callable securities. While higher interest rates would be expected to continue to increase the number of fixed-maturity holdings trading below 100 percent of amortized cost, we believe lower fixed-maturity security values due solely to interest rate changes would not signal a decline in credit quality. We continue to manage the portfolio with an eye toward both meeting current income needs and managing interest rate risk.

Our dynamic financial planning model uses analytical tools to assess market risks. As part of this model, the effective duration of the fixed-maturity portfolio is continually monitored by our investment department to evaluate the theoretical impact of interest rate movements.

The table below summarizes the effect of hypothetical changes in interest rates on the fair value of the fixed-maturity portfolio:

(In millions)	Interest Rate Shift in Basis Points
	-200		-100		—		100		200
At June 30, 2013	$	9,789	$	9,390	$	8,992	$	8,591	$	8,205
At December 31, 2012	$	9,888	$	9,479	$	9,093	$	8,704	$	8,320

The effective duration of the fixed-maturity portfolio as of June 30, 2013, was 4.4 years, compared with 4.2 years at year-end 2012. The above table is a theoretical presentation showing that an instantaneous, parallel shift in the yield curve of 100 basis points could produce an approximately 4.4 percent change in the fair value of the fixed‑maturity portfolio. Generally speaking, the higher a bond is rated, the more directly correlated movements in its fair value are to changes in the general level of interest rates, exclusive of call features. The fair values of average- to lower-rated corporate bonds are additionally influenced by the expansion or contraction of credit spreads.

In our dynamic financial planning model, the selected interest rate change of 100 to 200 basis points represents our view of a shift in rates that is quite possible over a one-year period. The rates modeled should not be considered a prediction of future events as interest rates may be much more volatile in the future. The analysis is not intended to provide a precise forecast of the effect of changes in rates on our results or financial condition, nor does it take into account any actions that we might take to reduce exposure to such risks.

EQUITY INVESTMENTS

Our equity investments, with a fair value totaling $3.875 billion at June 30, 2013, include $3.761 billion of common stock securities of companies generally with strong indications of paying and growing their dividends. Other criteria we evaluate include increasing sales and earnings, proven management and a favorable outlook. We believe our equity investment style is an appropriate long-term strategy. While our long-term financial position would be affected by prolonged changes in the market valuation of our investments, we believe our strong surplus position and cash flow provide a cushion against short-term fluctuations in valuation. Continued payment of cash dividends by the issuers of the common equities we hold can provide a floor to their valuation. A $100 million unrealized change in the value of the common stocks owned at period end would cause a change of $65 million, or approximately 40 cents per share, in our shareholders’ equity.

At June 30, 2013, our largest holding had a fair value of 3.4 percent of our publicly-traded common stock portfolio. Exxon Mobil Corporation (NYSE:XOM) was our largest single common stock investment, comprising 1.0 percent of the investment portfolio at the end of the second quarter of 2013.

UNREALIZED INVESTMENT GAINS AND LOSSES

At June 30, 2013, unrealized investment gains before taxes for the consolidated investment portfolio totaled $2.056 billion and unrealized investment losses amounted to $69 million.

The unrealized investment gains at June 30, 2013, were due to a pretax net gain position in our fixed-maturity portfolio of $564 million and a net gain position in our equity portfolio of $1.423 billion. The net gain position in our fixed-maturity portfolio has grown in recent years due largely to a declining interest rate environment. During the second quarter of 2013, the portfolio's net gain position declined $282 million largely due to rising interest rates. The net gain position for our current fixed-maturity holdings will naturally decline over time as individual securities mature. In addition, changes in interest rates can cause rapid, significant changes in fair values of fixed-maturity securities and the net gain position, as discussed in Quantitative and Qualitative Disclosures about Market Risk. The three largest contributors to our equity portfolio net gain position were ExxonMobil, Chevron (NYSE:CVX) and The Procter & Gamble Company (NYSE:PG) common stocks, which had a combined net gain position of $283 million.

Unrealized Investment Losses

We expect the number of securities trading below amortized cost to fluctuate as interest rates rise or fall and credit spreads expand or contract due to prevailing economic conditions. Further, amortized costs for some securities are revised through OTTI recognized in prior periods. At June 30, 2013, 449 of the 2,839 securities we owned had fair values below amortized cost, compared with 68 of the 2,784 securities we owned at year-end 2012. The 449 holdings with fair values below cost or amortized cost at June 30, 2013, represented 11.1 percent of fair value of our investment portfolio and $69 million in unrealized losses.

• 437 of the 449 holdings had fair values between 90 percent and 100 percent of amortized cost at June 30, 2013. Seven of these 437 holdings are equity securities that may be subject to OTTI charges taken through earnings should they not recover by the recovery dates we determined. The remaining 430 securities primarily consist of fixed-maturity securities whose current valuation is largely the result of interest rate factors. The fair value of these 437 securities was $1.397 billion, and they accounted for $66 million in unrealized losses.

• 12 of the 449 holdings had fair values between 70 percent and 90 percent of amortized cost at June 30, 2013. 11 of these are fixed-maturity securities that we believe will continue to pay interest and ultimately pay principal upon maturity. The issuers of these securities have strong cash flow to service their debt and meet their contractual obligation to make principal payments. The fair value of these 12 securities was $26 million, and they accounted for $3 million in unrealized losses.

• No securities were trading below 70 percent of amortized cost at June 30, 2013.

At June 30, 2013, four fixed-maturity securities with a total unrealized loss of $1 million had been in an unrealized loss position for 12 months or more. Of that total, no fixed-maturity securities had fair values below 70 percent of amortized cost; One fixed-maturity security with a fair value of less than $1 million had a fair value from 70 percent to less than 90 percent of amortized cost and accounted for less than $1 million in unrealized losses; and three fixed-maturity securities with a fair value of $13 million had fair values from 90 percent to less than 100 percent of amortized cost and accounted for $1 million in unrealized losses.

At June 30, 2013, no equity securities had been in an unrealized loss position for 12 months or more.

At June 30, 2013, applying our invested asset impairment policy, we determined that the $69 million in total unrealized losses in the table above were not other-than-temporarily impaired.

During the second quarter of 2013, no securities were written down through impairment charges, for a total of five during the six months ended June 30, 2013. OTTI resulted in pretax, noncash charges of none and $2 million for the three and six months ended June 30, 2013. During the same periods of 2012, we wrote down securities resulting in $14 million and $30 million in OTTI charges.

During full-year 2012, we wrote down 13 securities and recorded $33 million in OTTI charges. At December 31, 2012, four fixed-maturity investments with a total unrealized loss of $1 million had been in an unrealized loss position for 12 months or more. Of that total, no fixed-maturity investments had fair values below 70 percent of amortized cost. No equity investments had been in an unrealized loss position for 12 months or more as of December 31, 2012.

Item 4.        Controls and Procedures

Evaluation of Disclosure Controls and Procedures – The company maintains disclosure controls and procedures (as that term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (Exchange Act)).

Any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. The company’s management, with the participation of the company’s chief executive officer and chief financial officer, has evaluated the effectiveness of the design and operation of the company’s disclosure controls and procedures as of June 30, 2013. Based upon that evaluation, the company’s chief executive officer and chief financial officer concluded that the design and operation of the company’s disclosure controls and procedures provided reasonable assurance that the disclosure controls and procedures are effective to ensure:

• that information required to be disclosed in the company’s reports under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms, and

• that such information is accumulated and communicated to the company’s management, including its chief executive officer and chief financial officer, as appropriate, to allow timely decisions regarding required disclosures.

Changes in Internal Control over Financial Reporting – During the three months ended June 30, 2013, there were no changes in our internal controls over financial reporting that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

As of June 30, 2013, and December 31, 2012, we had no liability for unrecognized tax benefits. Details about our liability for unrecognized tax benefits are found in our 2012 Annual Report on Form 10-K, Item 8, Note 11, Income Taxes, Page 129.

The differences between the 35 percent statutory income tax rate and our effective income tax rate were as follows:

(Dollars in millions)	Three months ended June 30,										Six months ended June 30,
	2013					2012					2013					2012
Tax at statutory rate	$	52		35.0	%	$	10		35.0	%	$	128		35.0	%	$	49		35.0	%
Increase (decrease) resulting from:
Tax-exempt income from municipal bonds	(9		)	(6.1	)	(8		)	(27.6	)	(16		)	(4.4	)	(17		)	(12.1	)
Dividend received exclusion	(6		)	(4.2	)	(6		)	(20.7	)	(12		)	(3.3	)	(11		)	(7.8	)
Other	1			1.0		1			3.0		1			0.4		2			1.2
Provision (benefit) for income taxes	$	38		25.7	%	$	(3	)	(10.3	)%	$	101		27.7	%	$	23		16.3	%

The change in our effective tax rate was primarily due to changes in pretax income from underwriting results and realized investment gains and losses, compared with unchanged levels of permanent book-tax differences.

The net unrealized investment gains in our fixed-maturity portfolio are primarily the result of the current low interest rate environment that increased the fair value of our fixed-maturity portfolio. The three largest net unrealized investment gains in our common stock portfolio are from Exxon Mobil Corporation (NYSE:XOM), Chevron Corporation (NYSE:CVX) and The Procter & Gamble Company (NYSE:PG), which had a combined net gain position of $283 million. At At June 30, 2013, we had $16 million fair value of hybrid securities included in fixed maturities that follow Accounting Standards Codification (ASC) 815-15-25, Accountingfor Certain Hybrid Financial Instruments, compared with $31 million fair value of hybrid securities at December 31, 2012. The hybrid securities are carried at fair value, and the changes in fair value are included in realized investment gains and losses.

The table below provides fair values and unrealized losses by investment category and by the duration of the securities’ continuous unrealized loss position:

During the three and six months ended June 30, 2013 and 2012, there were no credit losses on fixed-maturity securities for which a portion of other-than-temporary impairment (OTTI) has been recognized in other comprehensive income.

During the quarter ended June 30, 2013, there were no other-than-temporarily impaired securities. At June 30, 2013, four fixed-maturity investments with a total unrealized loss of $1 million had been in an unrealized loss position for 12 months or more. Of that total, no fixed-maturity investments had fair values below 70 percent of amortized cost. There were no equity investments in an unrealized loss position for 12 months or more as of June 30, 2013.

At December 31, 2012, four fixed-maturity investments with a total unrealized loss of $1 million had been in an unrealized loss position for 12 months or more. Of that total, no fixed-maturity investments had fair values below

70 percent of amortized cost. There were no equity investments in an unrealized loss position for 12 months or more as of December 31, 2012.

Earnings Per Share [Abstract]

Net Income Per Common Share

NET INCOME PER COMMON SHARE

Basic earnings per share are computed based on the weighted average number of shares outstanding. Diluted earnings per share are computed based on the weighted average number of common and dilutive potential common shares outstanding using the treasury stock method.

The table shows calculations for basic and diluted earnings per share:

(Dollars in millions except share data in thousands)	Three months ended June 30,				Six months ended June 30,

Number of anti-dilutive stock-based awards	340		6,059		393		6,072

The current sources of dilution of our common shares are certain equity-based awards as discussed in our 2012 Annual Report on Form 10-K, Item 8, Note 17, Stock-Based Associate Compensation Plans, Page 135. The above table shows the number of anti-dilutive stock-based awards for the three and six months ended June 30, 2013 and 2012. We did not include these stock-based awards in the computation of net income per common share (diluted) because their exercise would have anti-dilutive effects.

Fair Value Disclosures [Abstract]

Fair Value Measurements

FAIR VALUE MEASUREMENTS

Fair Value Hierarchy

In accordance with accounting guidance for fair value measurements and disclosures, we categorized our financial instruments, based on the priority of the observable and market-based data for the valuation technique used, into a three-level fair value hierarchy. The fair value hierarchy gives the highest priority to quoted prices with readily available independent data in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable market inputs (Level 3). When various inputs for measurement fall within different levels of the fair value hierarchy, the lowest observable input that has a significant impact on fair value measurement is used. Our valuation techniques have not changed from those used at December 31, 2012, and ultimately management determines fair value. See our 2012 Annual Report on Form 10-K, Item 8, Note 3, Fair Value Measurements, Page 121, for information on characteristics and valuation techniques used in determining fair value.

Fair Value Disclosures for Assets

The following tables illustrate the fair value hierarchy for those assets measured at fair value on a recurring basis at June 30, 2013, and December 31, 2012. We do not have any material liabilities carried at fair value. There were no transfers between Level 1 and Level 2.

Each financial instrument that was deemed to have significant unobservable inputs when determining valuation is identified in the following tables by security type with a summary of changes in fair value as of June 30, 2013. Total Level 3 assets continue to be less than 1 percent of financial assets measured at fair value in the condensed consolidated balance sheets. Assets presented in the table below were valued based primarily on broker/dealer quotes for which there is a lack of transparency as to inputs used to develop the valuations. The quantitative detail of these unobservable inputs is neither provided nor reasonably available to us.

Accounting Policies

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. Our December 31, 2012, condensed consolidated balance sheet amounts are derived from the audited financial statements but do not include all disclosures required by GAAP.

Our June 30, 2013, 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 2012 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 2013-02, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income

In February 2013, the Financial Accounting Standards Board issued Accounting Standards Update (ASU) 2013-02, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income. ASU 2013-02 requires entities to present in either a single note or parenthetically on the face of the financial statements, the effect of significant amounts reclassified from each component of accumulated other comprehensive income based on its source and the income statement line items affected by the reclassification. The company adopted this ASU during the first quarter of 2013, and it did not have a material impact on our company’s financial position, cash flows or results of operations. See Note 7, Accumulated Other Comprehensive Income, for further details.

Deferred Costs [Abstract]

Deferred Acquisition Costs

DEFERRED ACQUISITION COSTS

Expenses directly related to successfully acquiring insurance policies – primarily commissions, premium taxes and underwriting costs – are deferred and amortized over the terms of the policies. We update our acquisition cost assumptions periodically to reflect actual experience, and we evaluate the costs for recoverability. The table below shows the deferred policy acquisition costs and asset reconciliation.

(In millions)	Three months ended June 30,						Six months ended June 30,
	2013			2012			2013			2012
Deferred policy acquisition costs asset at beginning of period	$	491		$	483		$	470		$	477
Capitalized deferred policy acquisition costs	203			192			401			362
Amortized deferred policy acquisition costs	(183		)	(181		)	(362		)	(337		)
Amortized shadow deferred policy acquisition costs	35			(10		)	37			(18		)
Deferred policy acquisition costs asset at end of period	$	546		$	484		$	546		$	484

No premium deficiencies were recorded in the condensed consolidated statements of income, as the sum of the anticipated loss and loss adjustment expenses, policyholder dividends and unamortized deferred acquisition expenses did not exceed the related unearned premiums and anticipated investment income.

Liability for Future Policy Benefits [Abstract]

Life Policy And Investment Contract Reserves

LIFE POLICY AND INVESTMENT CONTRACT RESERVES

We establish the reserves for traditional life insurance policies based on expected expenses, mortality, morbidity, withdrawal rates, timing of claim presentation and investment yields, including a provision for uncertainty. Once these assumptions are established, they generally are maintained throughout the lives of the contracts. We use both our own experience and industry experience, adjusted for historical trends, in arriving at our assumptions for expected mortality, morbidity and withdrawal rates as well as for expected expenses. We base our assumptions for expected investment income on our own experience adjusted for current economic conditions.

We establish reserves for the company’s universal life, deferred annuity and structured settlement policies equal to the cumulative account balances, which include premium deposits plus credited interest less charges and withdrawals. Some of our universal life policies contain no-lapse guarantee provisions. For these policies, we establish a reserve in addition to the account balance, based on expected no-lapse guarantee benefits and expected policy assessments.

This table summarizes our life policy and investment contract reserves:

(In millions)	June 30, 2013		December 31, 2012
Ordinary/traditional life	$	778	$	752

Reinsurance Disclosures [Abstract]

Reinsurance

REINSURANCE

Reinsurance mitigates the risk of highly uncertain exposures and limits the maximum net loss that can arise from large risks or risks concentrated in areas of exposure. Management's decisions about the appropriate level of risk retention are affected by various factors, including changes in our underwriting practices, capacity to retain risks and reinsurance market conditions. Primary components of our property and casualty reinsurance program include a property per risk treaty, property excess treaty, casualty per occurrence treaty, casualty excess treaty, property catastrophe treaty and catastrophe bonds.

Our condensed consolidated statements of income include earned consolidated property casualty insurance premiums on assumed and ceded business:

Our life insurance company purchases reinsurance for protection of a portion of the risk that is written. Primary components of our life reinsurance program include individual mortality coverage and aggregate catastrophe and accidental death coverage in excess of certain deductibles.

We use actuarial methods, models and judgment to estimate, as of a financial statement date, the property casualty loss and loss expense reserves required to pay for and settle all outstanding insured claims, including incurred but not reported (IBNR) claims, as of that date. The actuarial estimate is subject to review and adjustment by an inter-departmental committee that includes actuarial management that is familiar with relevant company and industry business, claims and underwriting trends, as well as general economic and legal trends that could affect future loss and loss expense payments. The amount we will actually have to pay for claims can be highly uncertain. This uncertainty, together with the size of our reserves, makes the loss and loss expense reserves our most significant estimate. The reserve for loss and loss expenses in the condensed consolidated balance sheets also included $65 million at June 30, 2013, and $59 million at June 30, 2012, for certain life and health loss and loss expense reserves.

For the three months ended June 30, 2013, we experienced $92 million of favorable development on prior accident years, including $66 million of favorable development in commercial lines and $26 million of favorable development in personal lines. There was $8 million from favorable development of catastrophe losses for the three months ended June 30, 2013, compared with $5 million of favorable development of catastrophe losses that occurred for the three months ended June 30, 2012.

For the six months ended June 30, 2013, we experienced $102 million of favorable development on prior accident years, including $78 million of favorable development in commercial lines, $22 million of favorable development in personal lines and $2 million favorable development in excess and surplus lines. There was $15 million from favorable development of catastrophe losses for the six months ended June 30, 2013, compared with $27 million of favorable development of catastrophe losses that occurred for the six months ended June 30, 2012.

Adopted Accounting Updates, Policy

ASU 2013-02, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income

In February 2013, the Financial Accounting Standards Board issued Accounting Standards Update (ASU) 2013-02, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income. ASU 2013-02 requires entities to present in either a single note or parenthetically on the face of the financial statements, the effect of significant amounts reclassified from each component of accumulated other comprehensive income based on its source and the income statement line items affected by the reclassification. The company adopted this ASU during the first quarter of 2013, and it did not have a material impact on our company’s financial position, cash flows or results of operations. See Note 7, Accumulated Other Comprehensive Income, for further details.

Commitments and Contingencies Disclosure [Abstract]

Commitments And Contingent Liabilities

COMMITMENTS AND CONTINGENT LIABILITIES

In the ordinary course of conducting business, the company and its subsidiaries are named as defendants in various legal proceedings. Most of these proceedings are claims litigation involving the company's insurance subsidiaries in which the company is either defending or providing indemnity for third-party claims brought against insureds or litigating first-party coverage claims. The company accounts for such activity throughthe establishment of unpaid loss and loss adjustment expense reserves. We believe that the ultimate liability, if any, with respect to such ordinary-course claims litigation, after consideration of provisions made for potential losses and costs of defense, is immaterial to our consolidated financial condition, results of operations and cash flows.

The company and its subsidiaries also are occasionally involved in other legal and regulatory proceedings, some of which assert claims for substantial amounts. These actions include, among others, putative class actions seeking certification of a state or national class. Such proceedings have alleged, for example, breach of an alleged duty to search national data bases to ascertain unreported deaths of insureds underlife insurance policies. The company's insurance subsidiaries also are occasionally parties to individual actions in which extra-contractual damages, punitive damages or penalties are sought, such asclaims alleging bad faith handling of insuranceclaims or writing unauthorized coverage and claims alleging discrimination by formerassociates.

On a quarterly basis, we review these outstanding matters. Under current accounting guidance, we establish accruals when it is probable that a loss has been incurred and we can reasonably estimate its potential exposure. The company accounts for such probable and estimable losses, if any, through the establishment of legal expense reserves. Based on our quarterly review, we believe that our accruals for probable and estimable losses are reasonable and that the amounts accrued do not have a material effect on our consolidated financial condition or results of operations. However, if any one or more of these matters results in a judgment against us or settlement for an amount that is significantly greater than the amount accrued, the resulting liability could have a material effect on the company's consolidated results of operations or cash flows. Based on our most recent review, our estimate for any other matters for which the risk of loss is not probable, but more than remote is less than $2 million.
