Accounting Policies [Abstract]
Nature of Operations	Nature of Operations Cincinnati Financial Corporation (CFC) operates through our insurance group and two complementary subsidiary companies. The Cincinnati Insurance Company leads our standard market property casualty insurance group that also includes two subsidiaries: The Cincinnati Casualty Company and The Cincinnati Indemnity Company. This group markets a broad range of standard market commercial and personal policies. The group focuses on delivery of quality customer service to our select group of 1,466 independent insurance agencies with 1,884 reporting locations across 39 states. Other subsidiaries of The Cincinnati Insurance Company include The Cincinnati Life Insurance Company, which markets life and disability income insurance and fixed annuities, and The Cincinnati Specialty Underwriters Insurance Company, which offers excess and surplus lines property casualty insurance products. The two CFC complementary subsidiaries are CSU Producer Resources Inc., which provides insurance brokerage services to our independent agencies so their clients can access our excess and surplus lines insurance products, and CFC Investment Company (CFC-I), which offers commercial leasing and financing services to our agents, their clients and other customers.
Basis of Presentation	Basis of Presentation Our consolidated financial statements include the accounts of the parent and its wholly owned subsidiaries and 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.
Earnings per Share	Earnings per Share Net income per common share is based on the weighted average number of common shares outstanding during each of the respective years. We calculate net income per common share (diluted) assuming the exercise or conversion of share‑based awards using the treasury stock method.
Stock-Based Compensation	Share-Based Compensation We account for share-based compensation in accordance with Accounting Standards Codification (ASC) 718, Compensation – Stock Compensation. We grant qualified and nonqualified share-based compensation under authorized plans. The stock options vest ratably over three years following the date of grant and are exercisable over 10-year periods. We grant service-based restricted stock units that cliff vest three years after the date of grant. We also grant performance-based restricted stock units that vest if certain market conditions are attained. In 2014, the CFC compensation committee approved share-based awards including incentive stock options, nonqualified stock options, service-based restricted and performance-based restricted stock units. See Note 17, Share-Based Associate Compensation Plans, for further details.
Employee Benefit Pension Plan	Employee Benefit Pension Plan We sponsor a defined benefit pension plan that was modified during 2008. We closed entry into the pension plan, and only participants 40 years of age or older could elect to remain in the plan. Our pension expense is based on certain actuarial assumptions and also is composed of several components that are determined using the projected unit credit actuarial cost method. Refer to Note 13, Employee Retirement Benefits, for more information about our defined benefit pension plan.
Property Casualty Insurance	Property Casualty Insurance The consolidated property casualty companies actively write property casualty insurance through independent agencies in 39 states. Our 10 largest states generated 62.8 percent and 63.8 percent of total earned premiums in 2014 and 2013, respectively. Ohio, our largest state, accounted for 17.7 percent and 18.5 percent of total earned premiums in 2014 and 2013, respectively. Illinois, Indiana, Pennsylvania, Georgia, Michigan and North Carolina each accounted for between 5 percent and 8 percent of total earned premiums in 2014. Our largest single agency relationship accounted for approximately 0.8 percent of our total property casualty earned premiums in 2014. No aggregate agency relationship locations under a single ownership structure accounted for more than 2.1 percent of our total property casualty earned premiums in 2014. We record revenues for installment charges as Fee revenues in the consolidated statements of income. Property casualty written premiums are deferred and recorded as earned premiums on a pro rata basis over the terms of the policies. We record as unearned premiums the portion of written premiums that applies to unexpired policy terms. Expenses associated with successfully acquiring insurance policies – commissions, premium taxes and underwriting costs – are deferred and amortized over the terms of the policies. All acquisition costs are in accordance with ASU 2010-26, Accounting for Costs Associated with Acquiring or Renewing Insurance Contracts. We assess recoverability of deferred acquisition costs at the segment level, consistent with the way we acquire, service and manage insurance policies and measure profitability. We analyze our acquisition cost assumptions to reflect actual experience, and we evaluate potential premium deficiencies. Certain property casualty policies are not entered into policy underwriting systems as of the effective date of coverage. An actuarial estimate is made to determine the amount of these unprocessed written premiums. A large majority of the estimate is unearned and has no material impact on earned premiums. Premiums receivable are reviewed for impairment on a quarterly basis. We maintain an allowance for uncollectible premiums. We establish reserves to cover the expected cost of claims, losses and expenses related to investigating, processing and resolving claims. Although the appropriate amount of reserves is inherently uncertain, we base our decisions on past experience and current facts. Reserves are based on claims reported prior to the end of the year and estimates of unreported claims. We take into account the fact that we may recover some of our costs through salvage and subrogation. We regularly review and update reserves using the most current information available. Any resulting adjustments are reflected in current calendar year insurance losses and policyholder benefits.
Policyholder Dividends	Policyholder Dividends Certain workers’ compensation policies include the possibility of a policyholder earning a return of a portion of its premium in the form of a policyholder dividend. The dividend generally is calculated by determining the profitability of a policy year along with the associated premium. We reserve for all probable future policyholder dividend payments. We record policyholder dividends as other underwriting expenses.
Life Insurance	Life Insurance We offer several types of life insurance and disability income insurance, and we account for each according to the duration of the contract. Short-duration life and health contracts are written to cover claims that arise during a short, fixed term of coverage. We generally have the right to change the amount of premium charged or cancel the coverage at the end of each contract term. Group life insurance is an example. We record premiums for short-duration life and health contracts similarly to property casualty contracts. Long-duration contracts are written to provide coverage for an extended period of time. Traditional long-duration contracts require policyholders to pay scheduled gross premiums, generally not less frequently than annually, over the term of the coverage. Premiums for these contracts, such as whole life insurance and disability income insurance, are recognized as revenue when due. Some traditional long-duration contracts, such as ten-pay whole life insurance, have premium payment periods shorter than the period over which coverage is provided. For these contracts, the excess of premium over the amount required to pay expenses and benefits is recognized over the term of the coverage rather than over the premium payment period. We establish a liability for traditional long-duration contracts as we receive premiums. The amount of this liability is the present value of future expenses and benefits less the present value of future net premiums. Net premium is the portion of gross premium required to provide for all expenses and benefits. We estimate future expenses and benefits and net premium using assumptions for expected expenses, mortality, morbidity, withdrawal rates and investment income. We include a provision for deviation, meaning we allow for some uncertainty in making our assumptions. We establish our assumptions when the contract is issued, and we generally maintain those assumptions for the life of the contract. 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. We use our own experience and historical trends for setting our assumption for expected expenses. We base our assumption for expected investment income on our own experience, adjusted for current economic conditions. We capitalize acquisition costs for traditional long-duration contracts. We charge these capitalized costs associated with successfully acquiring traditional long-duration contract insurance policies over the premium-paying period of the policies. We use the same assumptions used in establishing the liability for the contract. All acquisition costs reflect the retrospective adoption of Accounting Standards Update (ASU) 2010-26, Accounting for Costs Associated with Acquiring or Renewing Insurance Contracts. We update our acquisition cost assumptions periodically to reflect actual experience, and we evaluate our deferred acquisition cost for recoverability. Universal life contracts are long-duration contracts for which contractual provisions are not fixed, unlike whole life insurance. Universal life contracts allow policyholders to vary the amount of premium, within limits, without our consent. However, we may vary the mortality, expense charges and the interest crediting rate, within limits, used to accumulate policy values. We do not record universal life premiums as revenue. Instead we recognize as revenue the mortality charges, administration charges and surrender charges when received. Some of our universal life contracts assess administration charges in the early years of the contract that are compensation for services we will provide in the later years of the contract. These administration charges are deferred and are recognized over the period when we provide those future services. We maintain a liability equal to the policyholder account value. There is no provision for adverse deviation. 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. We capitalize acquisition costs for universal life long-duration contracts. We charge these capitalized costs to expenses over the term of coverage of the contract in accordance with the recognition of gross profit from the contract. When we charge deferred policy acquisition costs to expenses, we use assumptions based on our best estimates of long-term experience. We review and modify these assumptions on a regular basis.
Separate Accounts	Separate Accounts We have issued universal life contracts with guaranteed minimum returns, referred to as bank-owned life insurance contracts (BOLIs). A BOLI is designed so the bank is the policy owner and the policy beneficiary. We legally segregate and record as separate accounts the assets and liabilities for some of our BOLIs, based on the specific contract provisions. We guarantee minimum investment returns, account values and death benefits for our separate account BOLIs. Our other BOLIs are general account products. We carry the assets of separate account BOLIs at fair value. The liabilities on separate account BOLIs primarily are the contract holders’ claims to the related assets and are carried at an amount equal to the contract holders’ account value. At December 31, 2014, the current fair value of the BOLI invested assets and cash exceeded the current fair value of the contract holders’ account value by approximately $47 million. If the BOLI projected fair value were to fall below the value we guaranteed, a liability would be established with a corresponding charge to the company’s earnings. Generally, investment income and realized investment gains and losses of the separate accounts accrue directly to the contract holder, and we do not include them in the consolidated statements of income. Revenues and expenses related to separate accounts consist of contractual fees and mortality, surrender and expense risk charges. Also, each separate account BOLI includes a negotiated capital gain and loss sharing arrangement between the company and the bank. A percentage of each separate account’s realized capital gain and loss representing contract fees and assessments accrues to us and is transferred from the separate account to our general account and is recognized as revenue or expense. We record as revenues separate account investment management fees in Fee revenues of the consolidated statements of income.
Reinsurance	Reinsurance We reduce risk and uncertainty by buying property casualty and life reinsurance. Reinsurance contracts do not relieve us from our obligation to policyholders, but rather help protect our financial strength to perform that duty. All of these ceded reinsurance contracts transfer the economic risk of loss. We continue to assume risk with limited exposure as a reinsurer for other insurance companies, reinsurers and involuntary state pools. Both reinsurance assumed and ceded premiums are deferred and recorded as earned premiums on a pro rata basis over the terms of the contract. We estimate loss amounts recoverable from our reinsurers based on the reinsurance policy terms. Historically, our claims with reinsurers have been paid. We do not have an allowance for uncollectible reinsurance.
Cash And Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents are highly liquid instruments that include liquid debt instruments with original maturities of less than three months. These are carried at cost, which approximates fair value.
Investments	Investments Our portfolio investments are primarily in publicly traded fixed-maturity, equity and short-term investments. Fixed-maturity investments (taxable bonds, tax-exempt bonds, redeemable preferred equities and commercial mortgage backed securities) and equity investments (common and nonredeemable preferred equities) are classified as available for sale and recorded at fair value in the consolidated financial statements. The number of fixed-maturity securities with fair value below 100 percent of amortized cost can be expected to fluctuate as interest rates rise or fall. Because of our strong surplus and long-term investment horizon, our general intent is to hold fixed-maturity investments until maturity, regardless of short-term fluctuations in fair values. Our invested asset impairment policy states that fixed maturities below their amortized cost that the company (1) intends to sell or (2) more likely than not will be required to sell before recovery of their amortized cost basis are deemed to be other-than-temporarily impaired (OTTI). The amortized cost of any such securities is reduced to fair value as the new cost basis, and a realized loss is recorded in the period in which it is recognized. When these two criteria are not met, and the company believes that full collection of interest and/or principal is not likely, we determine the net present value of future cash flows by using the effective interest rate implicit in the security at the date of acquisition as the discount rate and compare that amount with the amortized cost and fair value of the security. The difference between the net present value of the expected future cash flows and amortized cost of the security is considered a credit loss and recognized as a realized loss in the period in which it occurred. The difference between the fair value and the net present value of the cash flows of the security, the noncredit loss, is recognized in other comprehensive income as an unrealized loss. We had no fixed-maturity securities with a noncredit loss for the years ended 2014 and 2013. When determining OTTI charges for our equity portfolio, our invested asset impairment policy considers qualitative and quantitative factors, including facts and circumstances specific to individual securities, asset classes, the financial condition of the issuer, changes in dividend payment, the length of time fair value had been less than cost, the severity of the decline in fair value below cost, the volatility of the security and our ability and intent to hold each position until its forecasted recovery. We include the noncredit portion of fixed-maturity OTTI charges and all other unrealized gains and losses on investments, net of taxes, in shareholders’ equity as accumulated other comprehensive income (AOCI). Realized gains and losses on investments are recognized in net income based on the trade date accounting method. Included within our other invested assets are $31 million of life policy loans and $37 million of private equity investments. Life policy loans are carried at the receivable value. The private equity investments provide their financial statements to us and generally report investments on their balance sheets at fair value. We use the equity method of accounting for private equity investments. Investment income consists mainly of interest and dividends. We record interest on an accrual basis and record dividends at the ex-dividend date. We amortize premiums and discounts on fixed-maturity securities using the effective interest method over the expected life of the security.
Fair Value Disclosures	Fair Value Disclosures We account for our investment portfolio at fair value and apply fair value measurements as defined by ASC 820, Fair Value Measurements and Disclosures, to financial instruments. Fair value is applicable to ASC 320, Investments-Debt and Equity Securities, and ASC 825, Financial Instruments. ASC 820 defines fair value as the exit price or the amount that would be (1) received to sell an asset or (2) paid to transfer a liability in an orderly transaction between marketplace participants at the measurement date. When determining an exit price, we rely upon observable market data whenever possible. We primarily base fair value for investments in equity and fixed-maturity securities (including redeemable preferred stock and assets held in separate accounts) on quoted market prices or on prices from a pricing vendor, an outside resource that supplies global securities pricing, dividend, corporate action and descriptive information to support fund pricing, securities operations, research and portfolio management. The company obtains and reviews the pricing service’s valuation methodologies and related inputs and validates these prices by replicating a sample across each asset class using a discounted cash flow model. When a price is not available from these sources, as in the case of securities that are not publicly traded, we determine the fair value using various inputs including quotes from independent brokers. The fair value of investments not priced by a pricing vendor is less than 1 percent of the fair value of our total investment portfolio. For the purpose of ASC 825 disclosure, we base fair value for long-term senior notes on market pricing of similar debt instruments that are actively trading. We base fair value for notes payable on our year-end outstanding balance because it is short term and tied to a variable interest rate. We estimate the fair value of liabilities for investment contracts and annuities using discounted cash flow calculations across a wide range of economic interest rate scenarios with a provision for our nonperformance risk. We estimate the fair value for policyholder loans on insurance contracts using a discounted cash flow model. Determination of fair value for structured settlements assumes the discount rates used to calculate the present value of expected payments are the risk-free spot rates plus an A3 rated bond spread for financial issuers at December 31, 2014, to account for nonperformance risk. See Note 3, Fair Value Measurements, for further details.
Land, Building And Equipment	Land, Building and Equipment We record land at cost, and record building and equipment at cost less accumulated depreciation. Equipment held under capital leases also is classified as property and equipment with the related lease obligations recorded as liabilities. We capitalize and amortize costs for internally developed computer software during the application development stage. These costs generally consist of external consulting, payroll and payroll-related costs. Our depreciation is based on estimated useful lives (ranging from three years to 39.5 years) using straight-line and accelerated methods. Depreciation expense was $37 million for each year in 2014, 2013 and 2012. We monitor land, building and equipment and software assets for potential impairments. Potential impairments may include a significant decrease in the fair values of the assets, considerable cost overruns on projects, a change in legal factors or business climate or other factors that indicate that the carrying amount may not be recoverable or useful. There were no recorded land, building and equipment impairments for 2014, 2013 or 2012.
Income Taxes	Income Taxes We calculate deferred income tax liabilities and assets using tax rates in effect when temporary differences in financial statement income and taxable income are expected to reverse. We recognize deferred income taxes for numerous temporary differences between our taxable income and financial statement income and other changes in shareholders’ equity. Such temporary differences relate primarily to unrealized gains and losses on investments and differences in the recognition of deferred acquisition costs, unearned premium and insurance reserves. We charge deferred income taxes associated with balances that impact other comprehensive income, such as unrealized appreciation and depreciation of investments (except the amounts related to the effect of income tax rate changes), to shareholders’ equity in AOCI. We charge deferred taxes associated with other differences to income. See Note 11, Income Taxes, for further detail on our uncertain tax positions. Although no Internal Revenue Service (IRS) penalties currently are accrued, if incurred, they would be recognized as a component of income tax expense.
Finance Receivables	Finance Receivables Our leasing subsidiary provides auto and equipment direct financing (leases and loans) to commercial and individual clients. We generally transfer ownership of the property to the client as the terms of the leases expire. Our lease contracts contain bargain purchase options. We account for these leases and loans as direct financing-type leases. We capitalize and amortize lease or loan origination costs over the life of the financing, using the effective interest method. These costs may include, but are not limited to finder fees, broker fees, filing fees and the cost of credit reports. We record income in the Other revenues of the consolidated statements of income over the financing term using the effective interest method. Finance receivables are reviewed for impairment on a quarterly basis and considered insignificant to our consolidated financial condition, results of operations and cash flows.
Subsequent Events	Subsequent Events There were no subsequent events requiring adjustment to the financial statements or disclosure.
Pending Accounting Updates	Pending Accounting Updates ASU 2014-09, Revenue from Contracts with Customers In May 2014, the Financial Accounting Standards Board (FASB) issued ASU 2014-09, Revenue from Contracts with Customers. ASU 2014-09 requires an entity to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods and services. Insurance contracts do not fall within the scope of this ASU. The effective date of ASU 2014-09 is for annual reporting periods beginning after December 15, 2016. The ASU has not yet been adopted; however, there is not expected to be a material impact on our company’s consolidated financial position, cash flows or results of operations. ASU 2014-12, Compensation-Stock Compensation: Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period In June 2014, the FASB Issued ASU 2014-12, Compensation-Stock Compensation: Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period. ASU 2014-12 requires that performance targets that affect vesting and that could be achieved after the requisite service period be treated as performance conditions. The effective date of ASU 2014-12 is for interim and annual reporting periods beginning after December 15, 2015. The ASU has not yet been adopted and will not have a material impact on our company’s consolidated financial position, cash flows or results of operations. ASU 2015-02, Consolidation (Topic 810) - Amendments to the Consolidation Analysis In February 2015, the FASB Issued ASU 2015-02, Consolidation (Topic 810) - Amendments to the Consolidation Analysis. ASU 2015-02 makes amendments to the current consolidation guidance, focusing mainly on the investment management industry; however entities across all industries will be impacted. The effective date of ASU 2015-02 is for interim and annual reporting periods beginning after December 15, 2015. The ASU has not yet been adopted; however, there is not expected to be a material impact on our company’s consolidated financial position, cash flows or results of operations.

Summary of Significant Accounting Policies (Policies)

12 Months Ended

Dec. 31, 2014

Cincinnati Financial Corporation (CFC) operates through our insurance group and two complementary subsidiary companies.

The Cincinnati Insurance Company leads our standard market property casualty insurance group that also includes two subsidiaries: The Cincinnati Casualty Company and The Cincinnati Indemnity Company. This group markets a broad range of standard market commercial and personal policies. The group focuses on delivery of quality customer service to our select group of 1,466 independent insurance agencies with 1,884 reporting locations across 39 states. Other subsidiaries of The Cincinnati Insurance Company include The Cincinnati Life Insurance Company, which markets life and disability income insurance and fixed annuities, and The Cincinnati Specialty Underwriters Insurance Company, which offers excess and surplus lines property casualty insurance products.

The two CFC complementary subsidiaries are CSU Producer Resources Inc., which provides insurance brokerage services to our independent agencies so their clients can access our excess and surplus lines insurance products, and CFC Investment Company (CFC-I), which offers commercial leasing and financing services to our agents, their clients and other customers.

Basis of Presentation

Our consolidated financial statements include the accounts of the parent and its wholly owned subsidiaries and 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.

Earnings per Share

Net income per common share is based on the weighted average number of common shares outstanding during each of the respective years. We calculate net income per common share (diluted) assuming the exercise or conversion of share‑based awards using the treasury stock method.

Stock-Based Compensation

Share-Based Compensation

We account for share-based compensation in accordance with Accounting Standards Codification (ASC) 718, Compensation – Stock Compensation. We grant qualified and nonqualified share-based compensation under authorized plans. The stock options vest ratably over three years following the date of grant and are exercisable over 10-year periods. We grant service-based restricted stock units that cliff vest three years after the date of grant. We also grant performance-based restricted stock units that vest if certain market conditions are attained. In 2014, the CFC compensation committee approved share-based awards including incentive stock options, nonqualified stock options, service-based restricted and performance-based restricted stock units. See Note 17, Share-Based Associate Compensation Plans, for further details.

Employee Benefit Pension Plan

We sponsor a defined benefit pension plan that was modified during 2008. We closed entry into the pension plan, and only participants 40 years of age or older could elect to remain in the plan. Our pension expense is based on certain actuarial assumptions and also is composed of several components that are determined using the projected unit credit actuarial cost method. Refer to Note 13, Employee Retirement Benefits, for more information about our defined benefit pension plan.

Property Casualty Insurance

The consolidated property casualty companies actively write property casualty insurance through independent agencies in 39 states. Our 10 largest states generated 62.8 percent and 63.8 percent of total earned premiums in 2014 and 2013, respectively. Ohio, our largest state, accounted for 17.7 percent and 18.5 percent of total earned premiums in 2014 and 2013, respectively. Illinois, Indiana, Pennsylvania, Georgia, Michigan and North Carolina each accounted for between 5 percent and 8 percent of total earned premiums in 2014. Our largest single agency relationship accounted for approximately 0.8 percent of our total property casualty earned premiums in 2014. No aggregate agency relationship locations under a single ownership structure accounted for more than 2.1 percent of our total property casualty earned premiums in 2014. We record revenues for installment charges as Fee revenues in the consolidated statements of income.

Property casualty written premiums are deferred and recorded as earned premiums on a pro rata basis over the terms of the policies. We record as unearned premiums the portion of written premiums that applies to unexpired policy terms. Expenses associated with successfully acquiring insurance policies – commissions, premium taxes and underwriting costs – are deferred and amortized over the terms of the policies. All acquisition costs are in accordance with ASU 2010-26, Accounting for Costs Associated with Acquiring or Renewing Insurance Contracts. We assess recoverability of deferred acquisition costs at the segment level, consistent with the way we acquire, service and manage insurance policies and measure profitability. We analyze our acquisition cost assumptions to reflect actual experience, and we evaluate potential premium deficiencies.

Certain property casualty policies are not entered into policy underwriting systems as of the effective date of coverage. An actuarial estimate is made to determine the amount of these unprocessed written premiums. A large majority of the estimate is unearned and has no material impact on earned premiums.

Premiums receivable are reviewed for impairment on a quarterly basis. We maintain an allowance for uncollectible premiums.

We establish reserves to cover the expected cost of claims, losses and expenses related to investigating, processing and resolving claims. Although the appropriate amount of reserves is inherently uncertain, we base our decisions on past experience and current facts. Reserves are based on claims reported prior to the end of the year and estimates of unreported claims. We take into account the fact that we may recover some of our costs through salvage and subrogation. We regularly review and update reserves using the most current information available. Any resulting adjustments are reflected in current calendar year insurance losses and policyholder benefits.

Policyholder Dividends

Certain workers’ compensation policies include the possibility of a policyholder earning a return of a portion of its premium in the form of a policyholder dividend. The dividend generally is calculated by determining the profitability of a policy year along with the associated premium. We reserve for all probable future policyholder dividend payments. We record policyholder dividends as other underwriting expenses.

Life Insurance

We offer several types of life insurance and disability income insurance, and we account for each according to the duration of the contract. Short-duration life and health contracts are written to cover claims that arise during a short, fixed term of coverage. We generally have the right to change the amount of premium charged or cancel the coverage at the end of each contract term. Group life insurance is an example. We record premiums for short-duration life and health contracts similarly to property casualty contracts.

Long-duration contracts are written to provide coverage for an extended period of time. Traditional long-duration contracts require policyholders to pay scheduled gross premiums, generally not less frequently than annually, over the term of the coverage. Premiums for these contracts, such as whole life insurance and disability income insurance, are recognized as revenue when due. Some traditional long-duration contracts, such as ten-pay whole life insurance, have premium payment periods shorter than the period over which coverage is provided. For these contracts, the excess of premium over the amount required to pay expenses and benefits is recognized over the term of the coverage rather than over the premium payment period.

We establish a liability for traditional long-duration contracts as we receive premiums. The amount of this liability is the present value of future expenses and benefits less the present value of future net premiums. Net premium is the portion of gross premium required to provide for all expenses and benefits. We estimate future expenses and benefits and net premium using assumptions for expected expenses, mortality, morbidity, withdrawal rates and investment income. We include a provision for deviation, meaning we allow for some uncertainty in making our assumptions. We establish our assumptions when the contract is issued, and we generally maintain those assumptions for the life of the contract. 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. We use our own experience and historical trends for setting our assumption for expected expenses. We base our assumption for expected investment income on our own experience, adjusted for current economic conditions.

We capitalize acquisition costs for traditional long-duration contracts. We charge these capitalized costs associated with successfully acquiring traditional long-duration contract insurance policies over the premium-paying period of the policies. We use the same assumptions used in establishing the liability for the contract. All acquisition costs reflect the retrospective adoption of Accounting Standards Update (ASU) 2010-26, Accounting for Costs Associated with Acquiring or Renewing Insurance Contracts. We update our acquisition cost assumptions periodically to reflect actual experience, and we evaluate our deferred acquisition cost for recoverability.

Universal life contracts are long-duration contracts for which contractual provisions are not fixed, unlike whole life insurance. Universal life contracts allow policyholders to vary the amount of premium, within limits, without our consent. However, we may vary the mortality, expense charges and the interest crediting rate, within limits, used to accumulate policy values. We do not record universal life premiums as revenue. Instead we recognize as revenue the mortality charges, administration charges and surrender charges when received. Some of our universal life contracts assess administration charges in the early years of the contract that are compensation for services we will provide in the later years of the contract. These administration charges are deferred and are recognized over the period when we provide those future services.

We maintain a liability equal to the policyholder account value. There is no provision for adverse deviation. 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.

We capitalize acquisition costs for universal life long-duration contracts. We charge these capitalized costs to expenses over the term of coverage of the contract in accordance with the recognition of gross profit from the contract. When we charge deferred policy acquisition costs to expenses, we use assumptions based on our best estimates of long-term experience. We review and modify these assumptions on a regular basis.

Separate Accounts

We have issued universal life contracts with guaranteed minimum returns, referred to as bank-owned life insurance contracts (BOLIs). A BOLI is designed so the bank is the policy owner and the policy beneficiary. We legally segregate and record as separate accounts the assets and liabilities for some of our BOLIs, based on the specific contract provisions. We guarantee minimum investment returns, account values and death benefits for our separate account BOLIs. Our other BOLIs are general account products.

We carry the assets of separate account BOLIs at fair value. The liabilities on separate account BOLIs primarily are the contract holders’ claims to the related assets and are carried at an amount equal to the contract holders’ account value. At December 31, 2014, the current fair value of the BOLI invested assets and cash exceeded the current fair value of the contract holders’ account value by approximately $47 million. If the BOLI projected fair value were to fall below the value we guaranteed, a liability would be established with a corresponding charge to the company’s earnings.

Generally, investment income and realized investment gains and losses of the separate accounts accrue directly to the contract holder, and we do not include them in the consolidated statements of income. Revenues and expenses related to separate accounts consist of contractual fees and mortality, surrender and expense risk charges. Also, each separate account BOLI includes a negotiated capital gain and loss sharing arrangement between the company and the bank. A percentage of each separate account’s realized capital gain and loss representing contract fees and assessments accrues to us and is transferred from the separate account to our general account and is recognized as revenue or expense. We record as revenues separate account investment management fees in Fee revenues of the consolidated statements of income.

Reinsurance

We reduce risk and uncertainty by buying property casualty and life reinsurance. Reinsurance contracts do not relieve us from our obligation to policyholders, but rather help protect our financial strength to perform that duty. All of these ceded reinsurance contracts transfer the economic risk of loss. We continue to assume risk with limited exposure as a reinsurer for other insurance companies, reinsurers and involuntary state pools.

Both reinsurance assumed and ceded premiums are deferred and recorded as earned premiums on a pro rata basis over the terms of the contract. We estimate loss amounts recoverable from our reinsurers based on the reinsurance policy terms. Historically, our claims with reinsurers have been paid. We do not have an allowance for uncollectible reinsurance.

Cash And Cash Equivalents

Cash and Cash Equivalents

Cash and cash equivalents are highly liquid instruments that include liquid debt instruments with original maturities of less than three months. These are carried at cost, which approximates fair value.

Investments

Our portfolio investments are primarily in publicly traded fixed-maturity, equity and short-term investments. Fixed-maturity investments (taxable bonds, tax-exempt bonds, redeemable preferred equities and commercial mortgage backed securities) and equity investments (common and nonredeemable preferred equities) are classified as available for sale and recorded at fair value in the consolidated financial statements. The number of fixed-maturity securities with fair value below 100 percent of amortized cost can be expected to fluctuate as interest rates rise or fall. Because of our strong surplus and long-term investment horizon, our general intent is to hold fixed-maturity investments until maturity, regardless of short-term fluctuations in fair values.

Our invested asset impairment policy states that fixed maturities below their amortized cost that the company (1) intends to sell or (2) more likely than not will be required to sell before recovery of their amortized cost basis are deemed to be other-than-temporarily impaired (OTTI). The amortized cost of any such securities is reduced to fair value as the new cost basis, and a realized loss is recorded in the period in which it is recognized. When these two criteria are not met, and the company believes that full collection of interest and/or principal is not likely, we determine the net present value of future cash flows by using the effective interest rate implicit in the security at the date of acquisition as the discount rate and compare that amount with the amortized cost and fair value of the security. The difference between the net present value of the expected future cash flows and amortized cost of the security is considered a credit loss and recognized as a realized loss in the period in which it occurred. The difference between the fair value and the net present value of the cash flows of the security, the noncredit loss, is recognized in other comprehensive income as an unrealized loss. We had no fixed-maturity securities with a noncredit loss for the years ended 2014 and 2013.

When determining OTTI charges for our equity portfolio, our invested asset impairment policy considers qualitative and quantitative factors, including facts and circumstances specific to individual securities, asset classes, the financial condition of the issuer, changes in dividend payment, the length of time fair value had been less than cost, the severity of the decline in fair value below cost, the volatility of the security and our ability and intent to hold each position until its forecasted recovery.

We include the noncredit portion of fixed-maturity OTTI charges and all other unrealized gains and losses on investments, net of taxes, in shareholders’ equity as accumulated other comprehensive income (AOCI). Realized gains and losses on investments are recognized in net income based on the trade date accounting method.

Included within our other invested assets are $31 million of life policy loans and $37 million of private equity investments. Life policy loans are carried at the receivable value. The private equity investments provide their financial statements to us and generally report investments on their balance sheets at fair value. We use the equity method of accounting for private equity investments.

Investment income consists mainly of interest and dividends. We record interest on an accrual basis and record dividends at the ex-dividend date. We amortize premiums and discounts on fixed-maturity securities using the effective interest method over the expected life of the security.

Fair Value Disclosures

We account for our investment portfolio at fair value and apply fair value measurements as defined by ASC 820, Fair Value Measurements and Disclosures, to financial instruments. Fair value is applicable to ASC 320, Investments-Debt and Equity Securities, and ASC 825, Financial Instruments.

ASC 820 defines fair value as the exit price or the amount that would be (1) received to sell an asset or (2) paid to transfer a liability in an orderly transaction between marketplace participants at the measurement date. When determining an exit price, we rely upon observable market data whenever possible. We primarily base fair value for investments in equity and fixed-maturity securities (including redeemable preferred stock and assets held in separate accounts) on quoted market prices or on prices from a pricing vendor, an outside resource that supplies global securities pricing, dividend, corporate action and descriptive information to support fund pricing, securities operations, research and portfolio management. The company obtains and reviews the pricing service’s valuation methodologies and related inputs and validates these prices by replicating a sample across each asset class using a discounted cash flow model. When a price is not available from these sources, as in the case of securities that are not publicly traded, we determine the fair value using various inputs including quotes from independent brokers. The fair value of investments not priced by a pricing vendor is less than 1 percent of the fair value of our total investment portfolio.

For the purpose of ASC 825 disclosure, we base fair value for long-term senior notes on market pricing of similar debt instruments that are actively trading. We base fair value for notes payable on our year-end outstanding balance because it is short term and tied to a variable interest rate. We estimate the fair value of liabilities for investment contracts and annuities using discounted cash flow calculations across a wide range of economic interest rate scenarios with a provision for our nonperformance risk. We estimate the fair value for policyholder loans on insurance contracts using a discounted cash flow model. Determination of fair value for structured settlements assumes the discount rates used to calculate the present value of expected payments are the risk-free spot rates plus an A3 rated bond spread for financial issuers at December 31, 2014, to account for nonperformance risk. See Note 3, Fair Value Measurements, for further details.

Land, Building And Equipment

Land, Building and Equipment

We record land at cost, and record building and equipment at cost less accumulated depreciation. Equipment held under capital leases also is classified as property and equipment with the related lease obligations recorded as liabilities. We capitalize and amortize costs for internally developed computer software during the application development stage. These costs generally consist of external consulting, payroll and payroll-related costs. Our depreciation is based on estimated useful lives (ranging from three years to 39.5 years) using straight-line and accelerated methods. Depreciation expense was $37 million for each year in 2014, 2013 and 2012. We monitor land, building and equipment and software assets for potential impairments. Potential impairments may include a significant decrease in the fair values of the assets, considerable cost overruns on projects, a change in legal factors or business climate or other factors that indicate that the carrying amount may not be recoverable or useful. There were no recorded land, building and equipment impairments for 2014, 2013 or 2012.

Income Taxes

We calculate deferred income tax liabilities and assets using tax rates in effect when temporary differences in financial statement income and taxable income are expected to reverse. We recognize deferred income taxes for numerous temporary differences between our taxable income and financial statement income and other changes in shareholders’ equity. Such temporary differences relate primarily to unrealized gains and losses on investments and differences in the recognition of deferred acquisition costs, unearned premium and insurance reserves. We charge deferred income taxes associated with balances that impact other comprehensive income, such as unrealized appreciation and depreciation of investments (except the amounts related to the effect of income tax rate changes), to shareholders’ equity in AOCI. We charge deferred taxes associated with other differences to income.

See Note 11, Income Taxes, for further detail on our uncertain tax positions. Although no Internal Revenue Service (IRS) penalties currently are accrued, if incurred, they would be recognized as a component of income tax expense.

Finance Receivables

Our leasing subsidiary provides auto and equipment direct financing (leases and loans) to commercial and individual clients. We generally transfer ownership of the property to the client as the terms of the leases expire. Our lease contracts contain bargain purchase options. We account for these leases and loans as direct financing-type leases. We capitalize and amortize lease or loan origination costs over the life of the financing, using the effective interest method. These costs may include, but are not limited to finder fees, broker fees, filing fees and the cost of credit reports. We record income in the Other revenues of the consolidated statements of income over the financing term using the effective interest method. Finance receivables are reviewed for impairment on a quarterly basis and considered insignificant to our consolidated financial condition, results of operations and cash flows.
