Accounting Policies [Abstract]
Basis of Presentation	Note 1 -- Basis of Presentation Cigna Corporation and its subsidiaries (either individually or collectively referred to as “Cigna”, “the Company”, “we”, or “our”) is a global health services organization with a mission to help its customers improve their health, well-being and sense of security. Its insurance subsidiaries are major providers of medical, dental, disability, life and accident insurance and related products and services, the majority of which are offered through employers and other groups (e.g. governmental and non‐governmental organizations, unions and associations). Cigna also offers Medicare and Medicaid products and health, life and accident insurance coverages primarily to individuals in the U.S. and selected international markets. In addition to its ongoing operations described above, Cigna also has certain run‐off operations. The Consolidated Financial Statements include the accounts of Cigna Corporation and its subsidiaries. Intercompany transactions and accounts have been eliminated in consolidation. These Consolidated Financial Statements were prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”). Amounts recorded in the Consolidated Financial Statements necessarily reflect management's estimates and assumptions about medical costs, investment valuation, interest rates and other factors. Significant estimates are discussed throughout these Notes; however, actual results could differ from those estimates. The impact of a change in estimate is generally included in earnings in the period of adjustment. Certain reclassifications have been made to prior year amounts to conform to the current presentation. These interim Consolidated Financial Statements are unaudited but include all adjustments (including normal recurring adjustments) necessary, in the opinion of management, for a fair statement of financial position and results of operations for the periods reported. The interim Consolidated Financial Statements and notes should be read in conjunction with the Consolidated Financial Statements and Notes included in the Company's 2013 Form 10-K. The preparation of interim Consolidated Financial Statements necessarily relies heavily on estimates. This and certain other factors, including the seasonal nature of portions of the health care and related benefits business as well as competitive and other market conditions, call for caution in estimating full year results based on interim results of operations. Beginning in the first quarter of 2014, the Company combined the results of its run-off reinsurance business with Other Operations for segment reporting purposes. Prior year information has been conformed to the current year presentation. See Note 15 for additional information.
Changes in Accounting Pronouncements	Note 2 — Recent Accounting Pronouncements Fees Paid to the Federal Government by Health Insurers (Accounting Standards Update (“ASU”) 2011-06). Effective January 1, 2014, the Company adopted the Financial Accounting Standards Board's (“FASB”) accounting guidance for the health insurance industry assessment (the “fee”) mandated by the Patient Protection and Affordable Care Act of 2010 (“Health Care Reform”). The fee will be levied based on a ratio of an insurer's net health insurance premiums written for the previous calendar year compared to the U.S. health insurance industry total. Based on industry studies, the Company recorded a liability in accounts payable, accrued expenses and other liabilities in the first quarter of 2014 of approximately $240 million representing an estimate of the fee for 2014. A corresponding deferred cost was recorded in other assets, including other intangibles. The Company will update this estimate for any adjustment in subsequent quarters. During the first quarter of 2014, $60 million of the deferred cost was recognized in other operating expenses; the remainder will be recognized on a straight-line basis over the balance of 2014. This fee is not tax deductible. Investment Company Accounting (ASU 2013-08). Effective January 1, 2014, the Company adopted FASB's amended accounting guidance to change the criteria for reporting as an investment company, clarify the fair value measurement used by an investment company and require additional disclosures. This guidance also confirms that parent company accounting for an investment company should reflect fair value accounting. While this guidance applies to certain of the Company's security and real estate partnership investments, its adoption did not have a material impact on the Company's financial statements. Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income (“AOCI”) (ASU 2013-02). Effective January 1, 2013, the Company adopted new requirements to disclose the effect of items reclassified out of AOCI into net income for each individual line item impacted in the statement of income. See Note 13 for the Company's disclosures. Disclosures about Offsetting Assets and Liabilities (ASU 2011-11). The FASB's new requirements to disclose information related to certain investments on both a gross and net basis became effective January 1, 2013. The Company had no transactions or arrangements subject to these new disclosure requirements.
Investments	Review of declines in fair value. Management reviews fixed maturities with a decline in fair value from cost for impairment based on criteria that include: length of time and severity of decline; financial health and specific near term prospects of the issuer; changes in the regulatory, economic or general market environment of the issuer's industry or geographic region; and the Company's intent to sell or the likelihood of a required sale prior to recovery. Credit quality. The Company regularly evaluates and monitors credit risk, beginning with the initial underwriting of a mortgage loan and continuing throughout the investment holding period. Mortgage origination professionals employ an internal credit quality rating system designed to evaluate the relative risk of the transaction at each loan's origination that is then updated each year as part of the annual portfolio loan review. The Company evaluates and monitors credit quality on an ongoing basis, classifying each loan as a loan in good standing, potential problem loan or problem loan. Quality ratings are based on our evaluation of a number of key inputs related to the loan, including real estate market-related factors such as rental rates and vacancies, and property-specific inputs such as growth rate assumptions and lease rollover statistics. However, the two most significant contributors to the credit quality rating are the debt service coverage and loan-to-value ratios. The debt service coverage ratio measures the amount of property cash flow available to meet annual interest and principal payments on debt, with a ratio below 1.0 indicating that there is not enough cash flow to cover the required loan payments. The loan-to-value ratio, commonly expressed as a percentage, compares the amount of the loan to the fair value of the underlying property collateralizing the loan. The Company's annual in-depth review of its commercial mortgage loan investments is the primary mechanism for identifying emerging risks in the portfolio. The most recent review was completed by the Company's investment professionals in the second quarter of 2013 and included an analysis of each underlying property's most recent annual financial statements, rent rolls, operating plans, budgets, a physical inspection of the property and other pertinent factors. Based on historical results, current leases, lease expirations and rental conditions in each market, the Company estimates the current year and future stabilized property income and fair value, and categorizes the investments as loans in good standing, potential problem loans or problem loans. Quality ratings are adjusted between annual reviews if new property information is received or an event such as delinquency or a borrower's request for restructure causes management to believe that the Company's estimate of financial performance, fair value or the risk profile of the underlying property has been impacted. Potential problem mortgage loans are considered current (no payment more than 59 days past due), but exhibit certain characteristics that increase the likelihood of future default. The characteristics management considers include, but are not limited to, the deterioration of debt service coverage below 1.0, estimated loan-to-value ratios increasing to 100% or more, downgrade in quality rating and requests from the borrower for restructuring. In addition, loans are considered potential problems if principal or interest payments are past due by more than 30 but less than 60 days. Problem mortgage loans are either in default by 60 days or more or have been restructured as to terms, which could include concessions on interest rate, principal payment or maturity date. The Company monitors each problem and potential problem mortgage loan on an ongoing basis, and updates the loan categorization and quality rating when warranted. Impaired commercial mortgage loans. A commercial mortgage loan is considered impaired when it is probable that the Company will not collect all amounts due (principal and interest) according to the terms of the original loan agreement. These loans are included in either problem or potential problem loans. The Company assesses each loan individually for impairment, using the information obtained from the quality review process discussed above. Impaired loans are carried at the lower of unpaid principal balance or the fair value of the underlying real estate. In some cases when it is probable that the Company will not collect the interest due under the original agreements, the loan will be considered impaired but a related valuation reserve will not be recorded because the fair value of the underlying real estate is higher than the remaining carrying value of the loan. Because of the risk profile of the underlying investment, the Company recognizes interest income on problem mortgage loans only when payment is actually received.
Fair Value Measurements	The Company carries certain financial instruments at fair value in the financial statements including fixed maturities, equity securities, short-term investments and derivatives. Other financial instruments are measured at fair value under certain conditions, such as when impaired. Fair value is defined as the price at which an asset could be exchanged in an orderly transaction between market participants at the balance sheet date. A liability's fair value is defined as the amount that would be paid to transfer the liability to a market participant, not the amount that would be paid to settle the liability with the creditor. The Company's financial assets and liabilities carried at fair value have been classified based upon a hierarchy defined by GAAP. The hierarchy gives the highest ranking to fair values determined using unadjusted quoted prices in active markets for identical assets and liabilities (Level 1) and the lowest ranking to fair values determined using methodologies and models with unobservable inputs (Level 3). An asset's or a liability's classification is based on the lowest level of input that is significant to its measurement. For example, a financial asset or liability carried at fair value would be classified in Level 3 if unobservable inputs were significant to the instrument's fair value, even though the measurement may be derived using inputs that are both observable (Levels 1 and 2) and unobservable (Level 3). The Company estimates fair values using prices from third parties or internal pricing methods. Fair value estimates received from third-party pricing services are based on reported trade activity and quoted market prices when available, and other market information that a market participant may use to estimate fair value. The internal pricing methods are performed by the Company's investment professionals and generally involve using discounted cash flow analyses, incorporating current market inputs for similar financial instruments with comparable terms and credit quality, as well as other qualitative factors. In instances where there is little or no market activity for the same or similar instruments, fair value is estimated using methods, models and assumptions that the Company believes a hypothetical market participant would use to determine a current transaction price. These valuation techniques involve some level of estimation and judgment that becomes significant with increasingly complex instruments or pricing models. The Company is responsible for determining fair value, as well as the appropriate level within the fair value hierarchy, based on the significance of unobservable inputs. The Company reviews methodologies, processes and controls of third-party pricing services and compares prices on a test basis to those obtained from other external pricing sources or internal estimates. The Company performs ongoing analyses of both prices received from third-party pricing services and those developed internally to determine that they represent appropriate estimates of fair value. The controls completed by the Company and third-party pricing services include reviewing to ensure that prices do not become stale and whether changes from prior valuations are reasonable or require additional review. The Company also performs sample testing of sales values to confirm the accuracy of prior fair value estimates. Exceptions identified during these processes indicate that adjustments to prices are infrequent and do not significantly impact valuations. Inputs for instruments classified in Level 1 include unadjusted quoted prices for identical assets in active markets accessible at the measurement date. Active markets provide pricing data for trades occurring at least weekly and include exchanges and dealer markets. Assets in Level 1 include actively-traded U.S. government bonds and exchange-listed equity securities. Given the narrow definition of Level 1 and the Company's investment asset strategy to maximize investment returns, a relatively small portion of the Company's investment assets are classified in this category. Inputs for instruments classified in Level 2 include quoted prices for similar assets or liabilities in active markets, quoted prices from those willing to trade in markets that are not active, or other inputs that are market observable or can be corroborated by market data for the term of the instrument. Such other inputs include market interest rates and volatilities, spreads and yield curves. An instrument is classified in Level 2 if the Company determines that unobservable inputs are insignificant. Fixed maturities and equity securities. Approximately 90% of the Company's investments in fixed maturities and equity securities are classified in Level 2 including most public and private corporate debt and equity securities, federal agency and municipal bonds, non-government mortgage-backed securities and preferred stocks. Because many fixed maturities do not trade daily, third-party pricing services and internal methods often use recent trades of securities with similar features and characteristics. When recent trades are not available, pricing models are used to determine these prices. These models calculate fair values by discounting future cash flows at estimated market interest rates. Such market rates are derived by calculating the appropriate spreads over comparable U.S. Treasury securities, based on the credit quality, industry and structure of the asset. Typical inputs and assumptions to pricing models include, but are not limited to, a combination of benchmark yields, reported trades, issuer spreads, liquidity, benchmark securities, bids, offers, reference data, and industry and economic events. For mortgage-backed securities, inputs and assumptions may also include characteristics of the issuer, collateral attributes, prepayment speeds and credit rating. Nearly all of these instruments are valued using recent trades or pricing models. Less than 1% of the fair value of investments classified in Level 2 represent foreign bonds that are valued using a single unadjusted market-observable input derived by averaging multiple broker-dealer quotes, consistent with local market practice. Short-term investments are carried at fair value which approximates cost. On a regular basis the Company compares market prices for these securities to recorded amounts to validate that current carrying amounts approximate exit prices. The short-term nature of the investments and corroboration of the reported amounts over the holding period support their classification in Level 2. Other derivatives classified in Level 2 represent over-the-counter instruments such as interest rate and foreign currency swap contracts. Fair values for these instruments are determined using market observable inputs including forward currency and interest rate curves and widely published market observable indices. Credit risk related to the counterparty and the Company is considered when estimating the fair values of these derivatives. However, the Company is largely protected by collateral arrangements with counterparties, and determined that no adjustment for credit risk was required as of March 31, 2014 or December 31, 2013. Level 2 also includes exchange-traded interest rate swap contracts. Credit risk related to the clearinghouse counterparty and the Company is considered minimal when estimating the fair values of these derivatives because of upfront margin deposits and daily settlement requirements. The nature and use of these other derivatives are described in Note 9. Certain inputs for instruments classified in Level 3 are unobservable (supported by little or no market activity) and significant to their resulting fair value measurement. Unobservable inputs reflect the Company's best estimate of what hypothetical market participants would use to determine a transaction price for the asset or liability at the reporting date. The Company classifies certain newly issued, privately-placed, complex or illiquid securities, as well as assets and liabilities relating to GMIB, in Level 3. Fair values of other asset and mortgage-backed securities, corporate and government fixed maturities are primarily determined using pricing models that incorporate the specific characteristics of each asset and related assumptions including the investment type and structure, credit quality, industry and maturity date in comparison to current market indices, spreads and liquidity of assets with similar characteristics. For other asset and mortgage-backed securities, inputs and assumptions for pricing may also include collateral attributes and prepayment speeds. Recent trades in the subject security or similar securities are assessed when available, and the Company may also review published research, as well as the issuer's financial statements, in its evaluation. Approximately 10% of fixed maturities classified in Level 3 represent single, unadjusted, non-binding broker quotes that are not considered market observable. Certain private equity investments and subordinated corporate fixed maturities, representing approximately 10% of securities included in Level 3, are valued at transaction price in the absence of market data indicating a change in the estimated fair values. The significant unobservable inputs used to value the following other asset and mortgage-backed securities are liquidity and weighting of credit spreads. When there is limited trading activity for the security, an adjustment for liquidity is made as of the measurement date that considers current market conditions, issuer circumstances and complexity of the security structure. An adjustment to weight credit spreads is needed to value a more complex bond structure with multiple underlying collateral and no standard market valuation technique. The weighting of credit spreads is primarily based on the underlying collateral's characteristics and their proportional cash flows supporting the bond obligations. The resulting wide range of unobservable adjustments in the table below is due to the varying liquidity and quality of the underlying collateral, ranging from high credit quality to below investment grade. The significant unobservable input used to value the following corporate and government fixed maturities is an adjustment for liquidity. When there is limited trading activity for the security, an adjustment is needed to reflect current market conditions and issuer circumstances. Significant increases in any of these inputs would result in a lower fair value measurement while decreases in these inputs would result in a higher fair value measurement. Generally, the unobservable inputs are not interrelated and a change in the assumption used for one unobservable input is not accompanied by a change in the other unobservable input. The tables do not include Level 3 securities when fair value and significant unobservable inputs were not developed directly by the Company, including securities using single, unadjusted non-binding broker quotes and securities valued at transaction price. See the preceding discussion regarding the Company's valuation processes and controls. As discussed in Note 5, the Company effectively exited from this business in 2013. Although these GMIB assets and liabilities must continue to be reported as derivatives at fair value, the only assumption that is expected to impact future shareholders' net income is the risk of non-performance. This assumption reflects a market participant's view of (a) the risk of the Company not fulfilling its GMIB obligations (GMIB liabilities) and (b) the credit risk that the reinsurers do not pay their obligations (GMIB assets). The Company reports GMIB liabilities and assets as derivatives at fair value because cash flows of these liabilities and assets are affected by equity markets and interest rates, but are without significant life insurance risk and are settled in lump sum payments. Under the terms of these written and purchased contracts, the Company periodically receives and pays fees based on either contractholders' account values or deposits increased at a contractual rate. The Company will also pay and receive cash depending on changes in account values and interest rates when contractholders first elect to receive minimum income payments. The Company estimates the fair value of the assets and liabilities for GMIB contracts by calculating the results for many scenarios run through a model utilizing various assumptions that include non-performance risk, among other things. The non-performance risk adjustment is incorporated by adding an additional spread to the discount rate in the calculation of both (a) the GMIB liabilities to reflect a market participant's view of the risk of the Company not fulfilling its GMIB obligations, and (b) the GMIB assets to reflect a market participant's view of the credit risk of the reinsurers, after considering collateral. Non-performance risk adjustments had an immaterial effect on shareholders' net income for the three months ended March 31, 2014 and 2013. Other assumptions that affect GMIB assets and liabilities include capital market assumptions (including market returns, interest rates and market volatilities of the underlying equity and bond mutual fund investments) and future annuitant behavior (including mortality, lapse, and annuity election rates). As certain assumptions used to estimate fair values for these contracts are largely unobservable (primarily related to future annuitant behavior), the Company classifies GMIB assets and liabilities in Level 3. The Company regularly evaluates each of the assumptions used in establishing these assets and liabilities. Significant decreases in assumed lapse rates or spreads used to calculate non-performance risk, or increases in assumed annuity election rates would result in higher fair value measurements. A change in one of these assumptions is not necessarily accompanied by a change in another assumption. GMIB liabilities are reported in the Company's Consolidated Balance Sheets in accounts payable, accrued expenses and other liabilities. GMIB assets associated with these contracts represent net receivables in connection with reinsurance that the Company has purchased from three external reinsurers and are reported in the Company's Consolidated Balance Sheets in other assets, including other intangibles. As noted in the tables above, total gains and losses included in shareholders' net income are reflected in the following captions in the Consolidated Statements of Income: Realized investment gains (losses) and net investment income for amounts related to fixed maturities and equity securities and realized investment gains (losses) for the impact of changes in non-performance risk related to GMIB assets and liabilities beginning February 4, 2013, similar to hedge ineffectiveness; and GMIB fair value (gain) loss for amounts related to GMIB assets and liabilities, except for the impact of changes in non-performance risk subsequent to February 4, 2013. In the tables above, gains and losses included in other comprehensive income are reflected in net unrealized appreciation (depreciation) on securities in the Consolidated Statements of Comprehensive Income. Reclassifications impacting Level 3 financial instruments are reported as transfers into or out of the Level 3 category as of the beginning of the quarter in which the transfer occurs. Therefore gains and losses in income only reflect activity for the period the instrument was classified in Level 3. Transfers into or out of the Level 3 category occur when unobservable inputs, such as the Company's best estimate of what a market participant would use to determine a current transaction price, become more or less significant to the fair value measurement. For the three months ended March 31, 2014 and March 31, 2013, transfers between Level 2 and Level 3 primarily reflect the change in significance of the unobservable inputs used to value certain public and private corporate bonds, principally related to liquidity of the securities and credit risk of the issuers. Because GMIB reinsurance arrangements remain in effect at the reporting date, the Company has reflected the total gain or loss for the period as the total gain or loss included in income attributable to instruments still held at the reporting date. However, the Company reduces the GMIB assets and liabilities resulting from these reinsurance arrangements when annuitants lapse, die, elect their benefit, or reach the age after which the right to elect their benefit expires. Separate account assets in Level 1 primarily include exchange-listed equity securities. Level 2 assets primarily include: corporate and structured bonds valued using recent trades of similar securities or pricing models that discount future cash flows at estimated market interest rates as described above; and actively-traded institutional and retail mutual fund investments and separate accounts priced using the daily net asset value which is the exit price. Separate account assets classified in Level 3 include investments primarily in securities partnerships, real estate and hedge funds generally valued based on the separate account's ownership share of the equity of the investee including changes in the fair values of its underlying investments. Some financial assets and liabilities are not carried at fair value each reporting period, but may be measured using fair value only under certain conditions, such as investments in real estate entities and commercial mortgage loans when they become impaired. Commercial mortgage loans. The Company estimates the fair value of commercial mortgage loans generally by discounting the contractual cash flows at estimated market interest rates that reflect the Company's assessment of the credit quality of the loans. Market interest rates are derived by calculating the appropriate spread over comparable U.S. Treasury rates, based on the property type, quality rating and average life of the loan. The quality ratings reflect the relative risk of the loan, considering debt service coverage, the loan-to-value ratio and other factors. Fair values of impaired mortgage loans are based on the estimated fair value of the underlying collateral generally determined using an internal discounted cash flow model. The fair value measurements were classified in Level 3 because the cash flow models incorporate significant unobservable inputs. Contractholder deposit funds, excluding universal life products. Generally, these funds do not have stated maturities. Approximately 60% of these balances can be withdrawn by the customer at any time without prior notice or penalty. The fair value for these contracts is the amount estimated to be payable to the customer as of the reporting date, which is generally the carrying value. Most of the remaining contractholder deposit funds are reinsured by the buyers of the individual life and annuity and retirement benefits businesses. The fair value for these contracts is determined using the fair value of these buyers' assets supporting these reinsured contracts. The Company had reinsurance recoverables equal to the carrying values of these reinsured contracts. These instruments were classified in Level 3 because certain inputs are unobservable (supported by little or no market activity) and significant to their resulting fair value measurement. Long-term debt, including current maturities, excluding capital leases. The fair value of long-term debt is based on quoted market prices for recent trades. When quoted market prices are not available, fair value is estimated using a discounted cash flow analysis and the Company's estimated current borrowing rate for debt of similar terms and remaining maturities. These measurements were classified in Level 2 because the fair values are based on quoted market prices or other inputs that are market observable or can be corroborated by market data.
Derivative Financial Instruments	Accounting policy. Using cash flow hedge accounting, fair values are reported in other long-term investments or other liabilities. Changes in fair value are reported in accumulated other comprehensive income and amortized into net investment income or reported in other realized investment gains and losses as interest or principal payments are received. Cash flows. Under the terms of these various contracts, the Company periodically exchanges cash flows between variable and fixed interest rates and/or between two currencies for both principal and interest. Foreign currency swaps are primarily Euros, Canadian dollars, Australian dollars, Japanese yen, and British pounds, and have terms for periods of up to seven years. Net interest cash flows are reported in operating activities. Accounting Policy. Using fair value hedge accounting, the fair values of the swap contracts are reported in other assets or other liabilities. As the critical terms of these swaps match those of the long-term debt being hedged, the carrying value of the hedged debt is adjusted to reflect changes in its fair value driven by LIBOR. The effects of those adjustments on other operating expense are offset by the effects of corresponding changes in the swaps' fair value. Interest expense includes the difference between the variable and fixed interest rates. Cash flows. Under the terms of these contracts, the Company provides upfront margin and settles fair value changes and net interest between variable and fixed interest rates daily with the clearinghouses. Net interest cash flows are reported in operating activities.

Changes in Accounting Pronouncements

Note 2 — Recent Accounting Pronouncements

Fees Paid to the Federal Government by Health Insurers (Accounting Standards Update (“ASU”) 2011-06). Effective January 1, 2014, the Company adopted the Financial Accounting Standards Board's (“FASB”) accounting guidance for the health insurance industry assessment (the “fee”) mandated by the Patient Protection and Affordable Care Act of 2010 (“Health Care Reform”). The fee will be levied based on a ratio of an insurer's net health insurance premiums written for the previous calendar year compared to the U.S. health insurance industry total. Based on industry studies, the Company recorded a liability in accounts payable, accrued expenses and other liabilities in the first quarter of 2014 of approximately $240 million representing an estimate of the fee for 2014. A corresponding deferred cost was recorded in other assets, including other intangibles. The Company will update this estimate for any adjustment in subsequent quarters. During the first quarter of 2014, $60 million of the deferred cost was recognized in other operating expenses; the remainder will be recognized on a straight-line basis over the balance of 2014. This fee is not tax deductible.

Investment Company Accounting (ASU 2013-08). Effective January 1, 2014, the Company adopted FASB's amended accounting guidance to change the criteria for reporting as an investment company, clarify the fair value measurement used by an investment company and require additional disclosures. This guidance also confirms that parent company accounting for an investment company should reflect fair value accounting. While this guidance applies to certain of the Company's security and real estate partnership investments, its adoption did not have a material impact on the Company's financial statements.

Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income (“AOCI”) (ASU 2013-02). Effective January 1, 2013, the Company adopted new requirements to disclose the effect of items reclassified out of AOCI into net income for each individual line item impacted in the statement of income. See Note 13 for the Company's disclosures.

Disclosures about Offsetting Assets and Liabilities (ASU 2011-11). The FASB's new requirements to disclose information related to certain investments on both a gross and net basis became effective January 1, 2013. The Company had no transactions or arrangements subject to these new disclosure requirements.

Investments

Review of declines in fair value. Management reviews fixed maturities with a decline in fair value from cost for impairment based on criteria that include:

length of time and severity of decline;

financial health and specific near term prospects of the issuer;
changes in the regulatory, economic or general market environment of the issuer's industry or geographic region; and
the Company's intent to sell or the likelihood of a required sale prior to recovery.

Credit quality. The Company regularly evaluates and monitors credit risk, beginning with the initial underwriting of a mortgage loan and continuing throughout the investment holding period. Mortgage origination professionals employ an internal credit quality rating system designed to evaluate the relative risk of the transaction at each loan's origination that is then updated each year as part of the annual portfolio loan review. The Company evaluates and monitors credit quality on an ongoing basis, classifying each loan as a loan in good standing, potential problem loan or problem loan.

Quality ratings are based on our evaluation of a number of key inputs related to the loan, including real estate market-related factors such as rental rates and vacancies, and property-specific inputs such as growth rate assumptions and lease rollover statistics. However, the two most significant contributors to the credit quality rating are the debt service coverage and loan-to-value ratios. The debt service coverage ratio measures the amount of property cash flow available to meet annual interest and principal payments on debt, with a ratio below 1.0 indicating that there is not enough cash flow to cover the required loan payments. The loan-to-value ratio, commonly expressed as a percentage, compares the amount of the loan to the fair value of the underlying property collateralizing the loan.

The Company's annual in-depth review of its commercial mortgage loan investments is the primary mechanism for identifying emerging risks in the portfolio. The most recent review was completed by the Company's investment professionals in the second quarter of 2013 and included an analysis of each underlying property's most recent annual financial statements, rent rolls, operating plans, budgets, a physical inspection of the property and other pertinent factors. Based on historical results, current leases, lease expirations and rental conditions in each market, the Company estimates the current year and future stabilized property income and fair value, and categorizes the investments as loans in good standing, potential problem loans or problem loans.

Quality ratings are adjusted between annual reviews if new property information is received or an event such as delinquency or a borrower's request for restructure causes management to believe that the Company's estimate of financial performance, fair value or the risk profile of the underlying property has been impacted.

Potential problem mortgage loans are considered current (no payment more than 59 days past due), but exhibit certain characteristics that increase the likelihood of future default. The characteristics management considers include, but are not limited to, the deterioration of debt service coverage below 1.0, estimated loan-to-value ratios increasing to 100% or more, downgrade in quality rating and requests from the borrower for restructuring. In addition, loans are considered potential problems if principal or interest payments are past due by more than 30 but less than 60 days. Problem mortgage loans are either in default by 60 days or more or have been restructured as to terms, which could include concessions on interest rate, principal payment or maturity date. The Company monitors each problem and potential problem mortgage loan on an ongoing basis, and updates the loan categorization and quality rating when warranted.

Impaired commercial mortgage loans. A commercial mortgage loan is considered impaired when it is probable that the Company will not collect all amounts due (principal and interest) according to the terms of the original loan agreement. These loans are included in either problem or potential problem loans. The Company assesses each loan individually for impairment, using the information obtained from the quality review process discussed above. Impaired loans are carried at the lower of unpaid principal balance or the fair value of the underlying real estate. In some cases when it is probable that the Company will not collect the interest due under the original agreements, the loan will be considered impaired but a related valuation reserve will not be recorded because the fair value of the underlying real estate is higher than the remaining carrying value of the loan.

Because of the risk profile of the underlying investment, the Company recognizes interest income on problem mortgage loans only when payment is actually received.

The Company carries certain financial instruments at fair value in the financial statements including fixed maturities, equity securities, short-term investments and derivatives. Other financial instruments are measured at fair value under certain conditions, such as when impaired.

Fair value is defined as the price at which an asset could be exchanged in an orderly transaction between market participants at the balance sheet date. A liability's fair value is defined as the amount that would be paid to transfer the liability to a market participant, not the amount that would be paid to settle the liability with the creditor.

The Company's financial assets and liabilities carried at fair value have been classified based upon a hierarchy defined by GAAP. The hierarchy gives the highest ranking to fair values determined using unadjusted quoted prices in active markets for identical assets and liabilities (Level 1) and the lowest ranking to fair values determined using methodologies and models with unobservable inputs (Level 3). An asset's or a liability's classification is based on the lowest level of input that is significant to its measurement. For example, a financial asset or liability carried at fair value would be classified in Level 3 if unobservable inputs were significant to the instrument's fair value, even though the measurement may be derived using inputs that are both observable (Levels 1 and 2) and unobservable (Level 3).

The Company estimates fair values using prices from third parties or internal pricing methods. Fair value estimates received from third-party pricing services are based on reported trade activity and quoted market prices when available, and other market information that a market participant may use to estimate fair value. The internal pricing methods are performed by the Company's investment professionals and generally involve using discounted cash flow analyses, incorporating current market inputs for similar financial instruments with comparable terms and credit quality, as well as other qualitative factors. In instances where there is little or no market activity for the same or similar instruments, fair value is estimated using methods, models and assumptions that the Company believes a hypothetical market participant would use to determine a current transaction price. These valuation techniques involve some level of estimation and judgment that becomes significant with increasingly complex instruments or pricing models.

The Company is responsible for determining fair value, as well as the appropriate level within the fair value hierarchy, based on the significance of unobservable inputs. The Company reviews methodologies, processes and controls of third-party pricing services and compares prices on a test basis to those obtained from other external pricing sources or internal estimates. The Company performs ongoing analyses of both prices received from third-party pricing services and those developed internally to determine that they represent appropriate estimates of fair value. The controls completed by the Company and third-party pricing services include reviewing to ensure that prices do not become stale and whether changes from prior valuations are reasonable or require additional review. The Company also performs sample testing of sales values to confirm the accuracy of prior fair value estimates. Exceptions identified during these processes indicate that adjustments to prices are infrequent and do not significantly impact valuations.

Inputs for instruments classified in Level 1 include unadjusted quoted prices for identical assets in active markets accessible at the measurement date. Active markets provide pricing data for trades occurring at least weekly and include exchanges and dealer markets.

Assets in Level 1 include actively-traded U.S. government bonds and exchange-listed equity securities. Given the narrow definition of Level 1 and the Company's investment asset strategy to maximize investment returns, a relatively small portion of the Company's investment assets are classified in this category.

Inputs for instruments classified in Level 2 include quoted prices for similar assets or liabilities in active markets, quoted prices from those willing to trade in markets that are not active, or other inputs that are market observable or can be corroborated by market data for the term of the instrument. Such other inputs include market interest rates and volatilities, spreads and yield curves. An instrument is classified in Level 2 if the Company determines that unobservable inputs are insignificant.

Fixed maturities and equity securities. Approximately 90% of the Company's investments in fixed maturities and equity securities are classified in Level 2 including most public and private corporate debt and equity securities, federal agency and municipal bonds, non-government mortgage-backed securities and preferred stocks. Because many fixed maturities do not trade daily, third-party pricing services and internal methods often use recent trades of securities with similar features and characteristics. When recent trades are not available, pricing models are used to determine these prices. These models calculate fair values by discounting future cash flows at estimated market interest rates. Such market rates are derived by calculating the appropriate spreads over comparable U.S. Treasury securities, based on the credit quality, industry and structure of the asset. Typical inputs and assumptions to pricing models include, but are not limited to, a combination of benchmark yields, reported trades, issuer spreads, liquidity, benchmark securities, bids, offers, reference data, and industry and economic events. For mortgage-backed securities, inputs and assumptions may also include characteristics of the issuer, collateral attributes, prepayment speeds and credit rating.

Nearly all of these instruments are valued using recent trades or pricing models. Less than 1% of the fair value of investments classified in Level 2 represent foreign bonds that are valued using a single unadjusted market-observable input derived by averaging multiple broker-dealer quotes, consistent with local market practice.

Short-term investments are carried at fair value which approximates cost. On a regular basis the Company compares market prices for these securities to recorded amounts to validate that current carrying amounts approximate exit prices. The short-term nature of the investments and corroboration of the reported amounts over the holding period support their classification in Level 2.

Other derivatives classified in Level 2 represent over-the-counter instruments such as interest rate and foreign currency swap contracts. Fair values for these instruments are determined using market observable inputs including forward currency and interest rate curves and widely published market observable indices. Credit risk related to the counterparty and the Company is considered when estimating the fair values of these derivatives. However, the Company is largely protected by collateral arrangements with counterparties, and determined that no adjustment for credit risk was required as of March 31, 2014 or December 31, 2013. Level 2 also includes exchange-traded interest rate swap contracts. Credit risk related to the clearinghouse counterparty and the Company is considered minimal when estimating the fair values of these derivatives because of upfront margin deposits and daily settlement requirements. The nature and use of these other derivatives are described in Note 9.

Certain inputs for instruments classified in Level 3 are unobservable (supported by little or no market activity) and significant to their resulting fair value measurement. Unobservable inputs reflect the Company's best estimate of what hypothetical market participants would use to determine a transaction price for the asset or liability at the reporting date.

The Company classifies certain newly issued, privately-placed, complex or illiquid securities, as well as assets and liabilities relating to GMIB, in Level 3.

Fair values of other asset and mortgage-backed securities, corporate and government fixed maturities are primarily determined using pricing models that incorporate the specific characteristics of each asset and related assumptions including the investment type and structure, credit quality, industry and maturity date in comparison to current market indices, spreads and liquidity of assets with similar characteristics. For other asset and mortgage-backed securities, inputs and assumptions for pricing may also include collateral attributes and prepayment speeds. Recent trades in the subject security or similar securities are assessed when available, and the Company may also review published research, as well as the issuer's financial statements, in its evaluation. Approximately 10% of fixed maturities classified in Level 3 represent single, unadjusted, non-binding broker quotes that are not considered market observable. Certain private equity investments and subordinated corporate fixed maturities, representing approximately 10% of securities included in Level 3, are valued at transaction price in the absence of market data indicating a change in the estimated fair values.

The significant unobservable inputs used to value the following other asset and mortgage-backed securities are liquidity and weighting of credit spreads. When there is limited trading activity for the security, an adjustment for liquidity is made as of the measurement date that considers current market conditions, issuer circumstances and complexity of the security structure. An adjustment to weight credit spreads is needed to value a more complex bond structure with multiple underlying collateral and no standard market valuation technique. The weighting of credit spreads is primarily based on the underlying collateral's characteristics and their proportional cash flows supporting the bond obligations. The resulting wide range of unobservable adjustments in the table below is due to the varying liquidity and quality of the underlying collateral, ranging from high credit quality to below investment grade.

The significant unobservable input used to value the following corporate and government fixed maturities is an adjustment for liquidity. When there is limited trading activity for the security, an adjustment is needed to reflect current market conditions and issuer circumstances.

Significant increases in any of these inputs would result in a lower fair value measurement while decreases in these inputs would result in a higher fair value measurement. Generally, the unobservable inputs are not interrelated and a change in the assumption used for one unobservable input is not accompanied by a change in the other unobservable input. The tables do not include Level 3 securities when fair value and significant unobservable inputs were not developed directly by the Company, including securities using single, unadjusted non-binding broker quotes and securities valued at transaction price. See the preceding discussion regarding the Company's valuation processes and controls.

As discussed in Note 5, the Company effectively exited from this business in 2013. Although these GMIB assets and liabilities must continue to be reported as derivatives at fair value, the only assumption that is expected to impact future shareholders' net income is the risk of non-performance. This assumption reflects a market participant's view of (a) the risk of the Company not fulfilling its GMIB obligations (GMIB liabilities) and (b) the credit risk that the reinsurers do not pay their obligations (GMIB assets).

The Company reports GMIB liabilities and assets as derivatives at fair value because cash flows of these liabilities and assets are affected by equity markets and interest rates, but are without significant life insurance risk and are settled in lump sum payments. Under the terms of these written and purchased contracts, the Company periodically receives and pays fees based on either contractholders' account values or deposits increased at a contractual rate. The Company will also pay and receive cash depending on changes in account values and interest rates when contractholders first elect to receive minimum income payments. The Company estimates the fair value of the assets and liabilities for GMIB contracts by calculating the results for many scenarios run through a model utilizing various assumptions that include non-performance risk, among other things.

The non-performance risk adjustment is incorporated by adding an additional spread to the discount rate in the calculation of both (a) the GMIB liabilities to reflect a market participant's view of the risk of the Company not fulfilling its GMIB obligations, and (b) the GMIB assets to reflect a market participant's view of the credit risk of the reinsurers, after considering collateral. Non-performance risk adjustments had an immaterial effect on shareholders' net income for the three months ended March 31, 2014 and 2013.

Other assumptions that affect GMIB assets and liabilities include capital market assumptions (including market returns, interest rates and market volatilities of the underlying equity and bond mutual fund investments) and future annuitant behavior (including mortality, lapse, and annuity election rates). As certain assumptions used to estimate fair values for these contracts are largely unobservable (primarily related to future annuitant behavior), the Company classifies GMIB assets and liabilities in Level 3.

The Company regularly evaluates each of the assumptions used in establishing these assets and liabilities. Significant decreases in assumed lapse rates or spreads used to calculate non-performance risk, or increases in assumed annuity election rates would result in higher fair value measurements. A change in one of these assumptions is not necessarily accompanied by a change in another assumption.

GMIB liabilities are reported in the Company's Consolidated Balance Sheets in accounts payable, accrued expenses and other liabilities. GMIB assets associated with these contracts represent net receivables in connection with reinsurance that the Company has purchased from three external reinsurers and are reported in the Company's Consolidated Balance Sheets in other assets, including other intangibles.

As noted in the tables above, total gains and losses included in shareholders' net income are reflected in the following captions in the Consolidated Statements of Income:

Realized investment gains (losses) and net investment income for amounts related to fixed maturities and equity securities and realized investment gains (losses) for the impact of changes in non-performance risk related to GMIB assets and liabilities beginning February 4, 2013, similar to hedge ineffectiveness; and
GMIB fair value (gain) loss for amounts related to GMIB assets and liabilities, except for the impact of changes in non-performance risk subsequent to February 4, 2013.

In the tables above, gains and losses included in other comprehensive income are reflected in net unrealized appreciation (depreciation) on securities in the Consolidated Statements of Comprehensive Income.

Reclassifications impacting Level 3 financial instruments are reported as transfers into or out of the Level 3 category as of the beginning of the quarter in which the transfer occurs. Therefore gains and losses in income only reflect activity for the period the instrument was classified in Level 3.

Transfers into or out of the Level 3 category occur when unobservable inputs, such as the Company's best estimate of what a market participant would use to determine a current transaction price, become more or less significant to the fair value measurement. For the three months ended March 31, 2014 and March 31, 2013, transfers between Level 2 and Level 3 primarily reflect the change in significance of the unobservable inputs used to value certain public and private corporate bonds, principally related to liquidity of the securities and credit risk of the issuers.

Because GMIB reinsurance arrangements remain in effect at the reporting date, the Company has reflected the total gain or loss for the period as the total gain or loss included in income attributable to instruments still held at the reporting date. However, the Company reduces the GMIB assets and liabilities resulting from these reinsurance arrangements when annuitants lapse, die, elect their benefit, or reach the age after which the right to elect their benefit expires.

Separate account assets in Level 1 primarily include exchange-listed equity securities. Level 2 assets primarily include:

corporate and structured bonds valued using recent trades of similar securities or pricing models that discount future cash flows at estimated market interest rates as described above; and
actively-traded institutional and retail mutual fund investments and separate accounts priced using the daily net asset value which is the exit price.

Separate account assets classified in Level 3 include investments primarily in securities partnerships, real estate and hedge funds generally valued based on the separate account's ownership share of the equity of the investee including changes in the fair values of its underlying investments.

Some financial assets and liabilities are not carried at fair value each reporting period, but may be measured using fair value only under certain conditions, such as investments in real estate entities and commercial mortgage loans when they become impaired.

Commercial mortgage loans. The Company estimates the fair value of commercial mortgage loans generally by discounting the contractual cash flows at estimated market interest rates that reflect the Company's assessment of the credit quality of the loans. Market interest rates are derived by calculating the appropriate spread over comparable U.S. Treasury rates, based on the property type, quality rating and average life of the loan. The quality ratings reflect the relative risk of the loan, considering debt service coverage, the loan-to-value ratio and other factors. Fair values of impaired mortgage loans are based on the estimated fair value of the underlying collateral generally determined using an internal discounted cash flow model. The fair value measurements were classified in Level 3 because the cash flow models incorporate significant unobservable inputs.

Contractholder deposit funds, excluding universal life products. Generally, these funds do not have stated maturities. Approximately 60% of these balances can be withdrawn by the customer at any time without prior notice or penalty. The fair value for these contracts is the amount estimated to be payable to the customer as of the reporting date, which is generally the carrying value. Most of the remaining contractholder deposit funds are reinsured by the buyers of the individual life and annuity and retirement benefits businesses. The fair value for these contracts is determined using the fair value of these buyers' assets supporting these reinsured contracts. The Company had reinsurance recoverables equal to the carrying values of these reinsured contracts. These instruments were classified in Level 3 because certain inputs are unobservable (supported by little or no market activity) and significant to their resulting fair value measurement.

Long-term debt, including current maturities, excluding capital leases. The fair value of long-term debt is based on quoted market prices for recent trades. When quoted market prices are not available, fair value is estimated using a discounted cash flow analysis and the Company's estimated current borrowing rate for debt of similar terms and remaining maturities. These measurements were classified in Level 2 because the fair values are based on quoted market prices or other inputs that are market observable or can be corroborated by market data.

Derivative Financial Instruments

Accounting policy. Using cash flow hedge accounting, fair values are reported in other long-term investments or other liabilities. Changes in fair value are reported in accumulated other comprehensive income and amortized into net investment income or reported in other realized investment gains and losses as interest or principal payments are received.

Cash flows. Under the terms of these various contracts, the Company periodically exchanges cash flows between variable and fixed interest rates and/or between two currencies for both principal and interest. Foreign currency swaps are primarily Euros, Canadian dollars, Australian dollars, Japanese yen, and British pounds, and have terms for periods of up to seven years. Net interest cash flows are reported in operating activities.

Accounting Policy. Using fair value hedge accounting, the fair values of the swap contracts are reported in other assets or other liabilities. As the critical terms of these swaps match those of the long-term debt being hedged, the carrying value of the hedged debt is adjusted to reflect changes in its fair value driven by LIBOR. The effects of those adjustments on other operating expense are offset by the effects of corresponding changes in the swaps' fair value. Interest expense includes the difference between the variable and fixed interest rates.

Cash flows. Under the terms of these contracts, the Company provides upfront margin and settles fair value changes and net interest between variable and fixed interest rates daily with the clearinghouses. Net interest cash flows are reported in operating activities.
