The Company carries certain financial instruments at fair value in the financial statements including debt securities, certain equity securities, short-term investments and derivatives. Other financial instruments are measured at fair value only under certain conditions, such as when impaired or when there are observable price changes for equity securities with no readily determinable fair value.

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 would 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 and for assigning 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 executed by the Company include evaluating changes in prices and monitoring for potentially stale valuations. The Company also performs sample testing of sales values to confirm the accuracy of prior fair value estimates. The minimal exceptions identified during these processes indicate that adjustments to prices are infrequent and do not significantly impact valuations. An annual due-diligence review of the most significant pricing service is conducted to review their processes, methodologies and controls. This review includes a walk-through of inputs for a sample of securities held across various asset types to validate the documented pricing process.

The following table provides information as of December 31, 2020 and December 31, 2019 about the Company’s financial assets and liabilities carried at fair value. As a result of the U.S. Group Disability and Life business divestiture, debt securities with a fair value of $7.8 billion, primarily classified in Level 2 of the fair value hierarchy, were transferred to New York Life on December 31, 2020. See Note 5 for further information. Separate account assets are also recorded at fair value on the Company’s Consolidated Balance Sheets and are reported separately in the Separate Accounts section below as gains and losses related to these assets generally accrue directly to policyholders.

(2)As a practical expedient, certain real estate funds are carried at fair value based on the Company’s ownership share of the equity of the investee (Net Asset Value (“NAV”)) including changes in the fair value of its underlying investments. The Company has $50 million in unfunded commitments in these funds as of December 31, 2020.

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. A relatively small portion of the Company’s investment assets are classified in this category given the narrow definition of Level 1 and the Company’s investment asset strategy to maximize investment returns.

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.

Debt and equity securities. Approximately 94% of the Company’s investments in debt and equity securities are classified in Level 2 including most public and private corporate debt and hybrid equity securities, federal agency and municipal bonds, non-government mortgage-backed securities and preferred stocks. Third-party pricing services and internal methods often use recent trades of securities

with similar features and characteristics because many debt securities do not trade daily. Pricing models are used to determine these prices when recent trades are not available. 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 represents 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 that approximates cost. The Company compares market prices for these securities to recorded amounts on a regular basis 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.

Derivative assets and liabilities classified in Level 2 represent over-the-counter instruments such as foreign currency forward and 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 adjustments for credit risk were required as of December 31, 2020 or 2019. The nature and use of these derivative financial instruments are described in Note 11.

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.

Fair values of mortgage and other asset-backed securities, as well as corporate and government debt securities, 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. Inputs and assumptions for pricing may also include characteristics of the issuer, collateral attributes and prepayment speeds for mortgage and other asset-backed securities. Recent trades in the subject security or similar securities are assessed when available, and the Company may also review published research in its evaluation, as well as the issuer’s financial statements.

The following table summarizes the fair value and significant unobservable inputs used in pricing the following debt securities that were developed directly by the Company as of December 31, 2020 and 2019. The range and weighted average basis point (“bps”) amounts for liquidity and credit spreads (adjustment to discount rates) reflect the Company’s best estimates of the unobservable adjustments a market participant would make to calculate these fair values. These liquidity and credit spreads have increased over the reported periods, resulting from continued uncertainty over the economic impacts related to COVID-19.

Corporate and government debt securities. The significant unobservable input used to value the following corporate and government debt securities is an adjustment for liquidity. This adjustment is needed to reflect current market conditions and issuer circumstances when there is limited trading activity for the security.

Mortgage and other asset-backed securities. The significant unobservable inputs used to value the following mortgage and other asset-backed securities are liquidity and weighting of credit spreads. An adjustment for liquidity is made as of the measurement date that considers current market conditions, issuer circumstances and complexity of the security structure when there is limited trading activity for the security. 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.

(Fair value in millions )	December 31, 2020		December 31, 2019		Unobservable input December 31, 2020	December 31, 2020		December 31, 2019

Significant increases in liquidity or credit spreads would result in lower fair value measurements while decreases in these inputs would result in higher fair value measurements. The unobservable inputs are generally 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 following tables summarize the changes in financial assets and financial liabilities classified in Level 3 for the years ended December 31, 2020 and 2019. Gains and losses reported in these tables may include net changes in fair value that are attributable to both observable and unobservable inputs.

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. Market

activity typically decreases during periods of economic uncertainty, and this decrease in activity reduces the availability of market observable data. As a result, the level of unobservable judgement that must be applied to the pricing of certain instruments increases, and is typically observed through the widening of liquidity and credit spreads. Transfers between Level 2 and Level 3 during 2020 and 2019 primarily reflected changes in liquidity and credit risk estimates for certain private placement issuers across several sectors. Transfers into and out of Level 3 are higher in 2020 due to fluctuations in liquidity and credit spreads over the reported periods, resulting from continued uncertainty over the economic impacts related to COVID-19. See discussion under Quantitative Information about Unobservable Inputs above for more information.

Accounting policy. Separate account assets and liabilities are contractholder funds maintained in accounts with specific investment objectives. The assets of these accounts are legally segregated and are not subject to claims that arise out of any of the Company’s other businesses. These separate account assets are carried at fair value with equal amounts recorded for related separate account liabilities. The investment income and fair value gains and losses of separate account assets generally accrue directly to the contractholders and, together with their deposits and withdrawals, are excluded from the Company’s Consolidated Statements of Income and Cash Flows. Fees and charges earned for mortality risks, asset management or administrative services are reported in either Premiums or Fees and other revenues. Investments that are measured using the practical expedient of NAV are excluded from the fair value hierarchy.

(1)Non-guaranteed separate accounts included $4.2 billion as of December 31, 2020 and $4.0 billion as of December 31, 2019 in assets supporting the Company’s pension plans, including $0.3 billion classified in Level 3 as of December 31, 2020 and $0.2 billion classified in Level 3 as of December 31, 2019.

Separate account assets classified in Level 3 primarily support Cigna’s pension plans and include certain newly-issued, privately-placed, complex, or illiquid securities that are priced using methods discussed above, as well as commercial mortgage loans. Activity, including transfers into and out of Level 3, was not material in 2020 or 2019.

Separate account investments in securities partnerships, real estate and hedge funds are generally valued based on the separate account’s ownership share of the equity of the investee (NAV as a practical expedient) including changes in the fair values of its underlying investments. Substantially all of these assets support the Cigna Pension Plans. The following table provides additional information on these investments.


	Fair Value as of				Unfunded Commitment as of December 31, 2020		Redemption Frequency (if currently eligible)	Redemption Notice Period

As of December 31, 2020, the Company does not have plans to sell any of these assets at less than fair value. These investments are structured to satisfy longer-term investment objectives. Securities partnerships are contractually non-redeemable, and the underlying investment assets are expected to be liquidated by the fund managers within ten years after inception.

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 when investments become impaired, including investment real estate and commercial mortgage loans and certain equity securities with no readily determinable fair value. For 2020 and 2019, there were no such impairments. Equity securities with no readily determinable fair value are also measured at fair value when there are observable price changes from orderly transactions with the same issuer. There were $75 million in 2020 and $22 million in 2019 of realized investment gains relating to price changes for equity securities with no readily determinable fair value. Carrying values represented less than 1% of total investments as of both 2020 and 2019.

The following table includes the Company’s financial instruments not recorded at fair value that are subject to fair value disclosure requirements at December 31, 2020 and 2019. In addition to universal life products and finance leases, financial instruments that are carried in the Company’s Consolidated Financial Statements at amounts that approximate fair value are excluded from the following table.


		December 31, 2020				December 31, 2019
(In millions)	Classification in Fair Value Hierarchy	Fair Value		Carrying Value		Fair Value		Carrying Value
Commercial mortgage loans	Level 3	$	1,456	$	1,419	$	1,989	$	1,947
Long-term debt, including current maturities, excluding finance leases	Level 2	$	37,676	$	31,835	$	39,439	$	36,375

Off-balance sheet financial instruments include commitments to purchase debt securities or fund commercial mortgage loans at fixed rates of interest. The fair values of off-balance sheet financial instruments were not material as of December 31, 2020 and 2019.
