Investment Risks and Uncertainties

Investments are exposed to the following primary sources of risk: credit, interest rate, liquidity, market valuation, currency and real estate risk. The financial statement risks, stemming from such investment risks, are those associated with the determination of estimated fair values, the diminished ability to sell certain investments in times of strained market conditions, the recognition of ACL and impairments, the recognition of income on certain investments and the potential consolidation of VIEs. The use of different methodologies, assumptions and inputs relating to these financial statement risks may have a material effect on the amounts presented within the consolidated financial statements.

The determination of ACL and impairments is highly subjective and is based upon quarterly evaluations and assessments of known and inherent risks associated with the respective asset class. Such evaluations and assessments are revised as conditions change and new information becomes available.

The recognition of income on certain investments (e.g. structured securities, including mortgage-backed securities, asset-backed securities (“ABS”), certain structured investment transactions and FVO Securities) is dependent upon certain factors such as prepayments and defaults, and changes in such factors could result in changes in amounts to be earned.

Fixed Maturity Securities AFS

Fixed Maturity Securities AFS by Sector

The following table presents the fixed maturity securities AFS by sector. U.S. corporate and foreign corporate sectors include redeemable preferred stock. RMBS includes agency, prime, alternative and sub-prime mortgage-backed securities. ABS includes securities collateralized by corporate loans and consumer loans. Municipals includes taxable and tax-exempt revenue bonds and, to a much lesser extent, general obligations of states, municipalities and political subdivisions. Commercial mortgage-backed securities (“CMBS”) primarily includes securities collateralized by multiple commercial mortgage loans. RMBS, ABS and CMBS are collectively, “Structured Products.” In accordance with new credit loss guidance adopted January 1, 2020, securities that incurred a credit loss after December 31, 2019 and were still held as of

December 31, 2020, are presented net of ACL. In accordance with previous guidance, both the temporary loss and OTTI loss are presented for securities that were in an unrealized loss position as of December 31, 2019.

Methodology for Amortization of Premium and Accretion of Discount on Structured Products

Amortization of premium and accretion of discount on Structured Products considers the estimated timing and amount of prepayments of the underlying loans. Actual prepayment experience is periodically reviewed and effective yields are recalculated when differences arise between the originally anticipated and the actual prepayments received and currently anticipated. Prepayment assumptions for Structured Products are estimated using inputs obtained from third-party specialists and based on management’s knowledge of the current market. For credit-sensitive and certain prepayment-sensitive Structured Products, the effective yield is recalculated on a prospective basis. For all other Structured Products, the effective yield is recalculated on a retrospective basis.

Maturities of Fixed Maturity Securities AFS

The amortized cost, net of ACL, and estimated fair value of fixed maturity securities AFS, by contractual maturity date, were as follows at December 31, 2020:

	Due in One Year or Less		Due After One Year Through Five Years		Due After Five Years Through Ten Years		Due After Ten Years		Structured Products		Total Fixed Maturity Securities AFS
	(In millions)
Amortized cost, net of ACL	$	14,784	$	49,294	$	59,170	$	130,773	$	56,709	$	310,730
Estimated fair value	$	14,935	$	52,294	$	67,613	$	160,503	$	59,464	$	354,809

Actual maturities may differ from contractual maturities due to the exercise of call or prepayment options. Fixed maturity securities AFS not due at a single maturity date have been presented in the year of final contractual maturity. Structured Products are shown separately, as they are not due at a single maturity.

Evaluation of Fixed Maturity Securities AFS for Credit Loss

Evaluation and Measurement Methodologies

Management considers a wide range of factors about the security issuer and uses its best judgment in evaluating the cause of the decline in the estimated fair value of the security and in assessing the prospects for near-term recovery. Inherent in management’s evaluation of the security are assumptions and estimates about the operations of the issuer and its future earnings potential. Considerations used in the credit loss evaluation process include, but are not limited to: (i) the extent to which the estimated fair value has been below amortized cost, (ii) adverse conditions specifically related to a security, an industry sector or sub-sector, or an economically depressed geographic area, adverse change in the financial condition of the issuer of the security, changes in technology, discontinuance of a segment of the business that may affect future earnings, and changes in the quality of credit enhancement, (iii) payment structure of the security and likelihood of the issuer being able to make payments, (iv) failure of the issuer to make scheduled interest and principal payments, (v) whether the issuer, or series of issuers or an industry has suffered a catastrophic loss or has exhausted natural resources, (vi) whether the Company has the intent to sell or will more likely than not be required to sell a particular security before the decline in estimated fair value below amortized cost recovers, (vii) with respect to Structured Products, changes in forecasted cash flows after considering the changes in the financial condition of the underlying loan obligors and quality of underlying collateral, expected prepayment speeds, current and forecasted loss severity, consideration of the payment terms of the underlying assets backing a particular security, and the payment priority within the tranche structure of the security, (viii) changes in the rating of the security by a rating agency, and (ix) other subjective factors, including concentrations and information obtained from regulators.

The methodology and significant inputs used to determine the amount of credit loss are as follows:

•The Company calculates the recovery value by performing a discounted cash flow analysis based on the present value of future cash flows. The discount rate is generally the effective interest rate of the security at the time of purchase for fixed-rate securities and the spot rate at the date of evaluation of credit loss for floating-rate securities.

•When determining collectability and the period over which value is expected to recover, the Company applies considerations utilized in its overall credit loss evaluation process which incorporates information regarding the specific security, fundamentals of the industry and geographic area in which the security issuer operates, and overall macroeconomic conditions. Projected future cash flows are estimated using assumptions derived from management’s single best estimate, the most likely outcome in a range of possible outcomes, after giving consideration to a variety of variables that include, but are not limited to: payment terms of the security; the likelihood that the issuer can service the interest and principal payments; the quality and amount of any credit enhancements; the security’s position within the capital structure of the issuer; possible corporate restructurings or asset sales by the issuer; any private and public sector programs to restructure foreign government securities and municipals; and changes to the rating of the security or the issuer by rating agencies.

•Additional considerations are made when assessing the unique features that apply to certain Structured Products including, but not limited to: the quality of underlying collateral, historical performance of the underlying loan obligors, historical rent and vacancy levels, changes in the financial condition of the underlying loan obligors, expected prepayment speeds, current and forecasted loss severity, consideration of the payment terms of the underlying loans or assets backing a particular security, changes in the quality of credit enhancement and the payment priority within the tranche structure of the security.

With respect to securities that have attributes of debt and equity (“perpetual hybrid securities”), consideration is given in the credit loss analysis as to whether there has been any deterioration in the credit of the issuer and the likelihood of recovery in value of the securities that are in a severe unrealized loss position. Consideration is also given as to whether any perpetual hybrid securities with an unrealized loss, regardless of credit rating, have deferred any dividend payments.

After the adoption of new credit loss guidance on January 1, 2020, in periods subsequent to the recognition of an initial ACL on a security, the Company reassesses credit loss quarterly. Subsequent increases or decreases in the expected cash flow from the security result in corresponding decreases or increases in the ACL which are recorded within net investment gains (losses); however, the previously recorded ACL is not reduced to an amount below zero. Full or partial write-offs are deducted from the ACL in the period the security, or a portion thereof, is considered uncollectible. Recoveries of amounts previously written off are recorded to the ACL in the period received. When the

Company has the intent to sell the security or it is more likely than not that the Company will be required to sell the security before recovery of its amortized cost, any ACL is written off and the amortized cost is written down to estimated fair value through a charge within net investment gains (losses), which becomes the new amortized cost of the security.

In accordance with the previous guidance, methodologies to evaluate the recoverability of a security in an unrealized loss position were similar, except: (i) the length of time estimated fair value had been below amortized cost was considered for securities, and (ii) for non-functional currency denominated securities, the impact from weakening non-functional currencies on securities that were near maturity was considered in the evaluation. In addition, measurement methodologies were similar, except: (i) a fair value floor was not utilized to limit the credit loss recognized, (ii) the amortized cost of securities was adjusted for the OTTI to the expected recoverable amount and an ACL was not utilized, (iii) subsequent to a credit loss being recognized, increases in expected cash flows from the security did not result in an immediate increase in valuation recognized in earnings through net investment gains (losses) from reduction of the ACL instead such increases in value were recorded as unrealized gains in OCI, and (iv) in periods subsequent to the recognition of OTTI on a security, the Company accounted for the impaired security as if it had been purchased on the measurement date of the impairment; accordingly, the discount (or reduced premium) based on the new cost basis was accreted over the remaining term of the security in a prospective manner based on the amount and timing of estimated future cash flows.

Evaluation of Fixed Maturity Securities AFS in an Unrealized Loss Position

Gross unrealized losses on securities without an ACL decreased $215 million for the year ended December 31, 2020 to $1.4 billion primarily due to decreases in interest rates and movement in foreign currency exchange rates, partially offset by widening credit spreads.

Gross unrealized losses on securities without an ACL that have been in a continuous gross unrealized loss position for 12 months or greater were $401 million at December 31, 2020, or 28% of the total gross unrealized losses on securities without an ACL.

Investment Grade Fixed Maturity Securities AFS

Of the $401 million of gross unrealized losses on securities without an ACL that have been in a continuous gross unrealized loss position for 12 months or greater, $350 million, or 87%, were related to 600 investment grade securities. Unrealized losses on investment grade securities are principally related to widening credit spreads since purchase and, with respect to fixed-rate securities, rising interest rates since purchase.

Below Investment Grade Fixed Maturity Securities AFS

Of the $401 million of gross unrealized losses on securities without an ACL that have been in a continuous gross unrealized loss position for 12 months or greater, $51 million, or 13%, were related to 90 below investment grade securities. Unrealized losses on below investment grade securities are principally related to U.S. and foreign corporate securities (primarily industrial and consumer), foreign government securities and CMBS and are the result of significantly wider credit spreads resulting from higher risk premiums since purchase, largely due to economic and market uncertainty, as well as with respect to fixed-rate securities, rising interest rates since purchase. Management evaluates U.S. corporate and foreign corporate securities based on factors such as expected cash flows, financial condition and near-term and long-term prospects of the issuers. Management evaluates foreign government securities based on factors impacting the issuers such as expected cash flows, financial condition of the issuers and any country specific economic conditions or public sector programs to restructure foreign government securities. Management evaluates CMBS based on actual and projected cash flows after considering the quality of underlying collateral, credit enhancements, expected prepayment speeds, current and forecasted loss severity, the payment terms of the underlying assets backing a particular security and the payment priority within the tranche structure of the security.

Current Period Evaluation

At December 31, 2020, with respect to securities in an unrealized loss position without an ACL, the Company did not intend to sell these securities, and it was not more likely than not that the Company would be required to sell these securities before the anticipated recovery of the remaining amortized cost. Based on the Company’s current evaluation of its securities in an unrealized loss position without an ACL, the Company concluded that these securities had not incurred a credit loss and should not have an ACL at December 31, 2020.

Future provisions for credit loss will depend primarily on economic fundamentals, issuer performance (including changes in the present value of future cash flows expected to be collected), changes in credit ratings and collateral valuation.

Allowance for Credit Loss Methodology

After the adoption of new credit loss guidance on January 1, 2020, the Company records an allowance for expected lifetime credit loss in an amount that represents the portion of the amortized cost basis of mortgage loans that the Company does not expect to collect, resulting in mortgage loans being presented at the net amount expected to be collected. In determining the Company’s ACL, management: (i) pools mortgage loans that share similar risk characteristics, (ii) considers expected lifetime credit loss over the contractual term of its mortgage loans adjusted for expected prepayments and any extensions, and (iii) considers past events and current and forecasted economic conditions. Each of the Company’s commercial, agricultural and residential mortgage loan portfolio segments are evaluated separately. The ACL is calculated for each mortgage loan portfolio segment based on inputs unique to each loan portfolio segment. On a quarterly basis, mortgage loans within a portfolio segment that share similar risk characteristics, such as internal risk ratings or consumer credit scores, are pooled for calculation of ACL. On an ongoing basis, mortgage loans with dissimilar risk characteristics (i.e., loans with significant declines in credit quality), collateral dependent mortgage loans (i.e., when the borrower is experiencing financial difficulty, including when foreclosure is reasonably possible or probable) and reasonably expected troubled debt restructurings (“TDRs”) (i.e., the Company grants concessions to borrower that is experiencing financial difficulties) are evaluated individually for credit loss. The ACL for loans evaluated individually are established using the same methodologies for all three portfolio segments. For example, the ACL for a collateral dependent loan is established as the excess of amortized cost over the estimated fair value of the loan’s underlying collateral, less selling cost when foreclosure is probable. Accordingly, the change in the estimated fair value of collateral dependent loans, which are evaluated individually for credit loss, is recorded as a change in the ACL which is recorded on a quarterly basis as a charge or credit to earnings in net investment gains (losses).

In accordance with the previous guidance, evaluation and measurement methodologies in determining the ACL were similar, except: (i) credit loss was recognized when incurred (when it was probable, based on current information and events, that all amounts due under the loan agreement would not be collected), (ii) pooling of loans with similar risk characteristics was permitted, but not required, (iii) forecasts of economic conditions were not considered in the evaluation, (iv) measurement of the expected lifetime credit loss over the contractual term, or expected term, was not considered in the measurement, and (v) the credit loss for loans evaluated individually could also be determined using either discounted cash flows using the loans’ original effective interest rate or observable market prices.

Commercial and Agricultural Mortgage Loan Portfolio Segments

Commercial and agricultural mortgage loan ACL are calculated in a similar manner. Within each loan portfolio segment, commercial and agricultural, loans are pooled by internal risk rating. Estimated lifetime loss rates, which vary by internal risk rating, are applied to the amortized cost of each loan, excluding accrued investment income, on a quarterly basis to develop the ACL. Internal risk ratings are based on an assessment of the loan’s credit quality, which can change over time. The estimated lifetime loss rates are based on several loan portfolio segment-specific factors, including (i) the Company’s experience with defaults and loss severity, (ii) expected default and loss severity over the forecast period, (iii) current and forecasted economic conditions including growth, inflation, interest rates and unemployment levels, (iv) loan specific characteristics including loan-to-value (“LTV”) ratios, and (v) internal risk ratings. These evaluations are revised as conditions change and new information becomes available. The Company uses its several decades of historical default and loss severity experience which capture multiple economic cycles. The Company uses a forecast of economic assumptions for a two-year period for most of its commercial and agricultural mortgage loans, while a one-year period is used for loans originated in certain markets. After the applicable forecast period, the Company reverts to its historical loss experience using a straight-line basis over two years. For evaluations of commercial mortgage loans, in addition to historical experience, management considers factors that include the impact of a rapid change to the economy, which may not be reflected in the loan portfolio, recent loss and recovery trend experience as compared to historical loss and recovery experience, and loan specific characteristics including debt service coverage ratios (“DSCR”). In estimating expected lifetime credit loss over the term of its commercial mortgage loans, the Company adjusts for expected prepayment and extension experience during the forecast period using historical prepayment and extension experience considering the expected position in the economic cycle and the loan profile (i.e., floating rate, shorter-term fixed rate and longer-term fixed rate) and after the forecast period using long-term historical prepayment experience. For evaluations of agricultural mortgage loans, in addition to historical experience, management considers factors that include increased stress in certain sectors, which may be evidenced by higher delinquency rates, or a change in the number of higher risk loans. In estimating expected lifetime credit loss over the term of its agricultural mortgage loans, the Company’s experience is much less sensitive to the position in the economic cycle and by loan profile; accordingly, historical prepayment experience is used, while extension terms are not prevalent with the Company’s agricultural mortgage loans.

Commercial mortgage loans are reviewed on an ongoing basis, which review includes, but is not limited to, an analysis of the property financial statements and rent roll, lease rollover analysis, property inspections, market analysis, estimated valuations of the underlying collateral, LTV ratios, DSCR and tenant creditworthiness. The monitoring process focuses on higher risk loans, which include those that are classified as restructured, delinquent or in foreclosure, as well as loans with higher LTV ratios and lower DSCR. Agricultural mortgage loans are reviewed on an ongoing basis, which review includes, but is not limited to, property inspections, market analysis, estimated valuations of the underlying collateral, LTV ratios and borrower creditworthiness, as well as reviews on a geographic and property-type basis. The monitoring process for agricultural mortgage loans also focuses on higher risk loans.

For commercial mortgage loans, the primary credit quality indicator is the DSCR, which compares a property’s net operating income to amounts needed to service the principal and interest due under the loan. Generally, the lower the DSCR, the higher the risk of experiencing a credit loss. The Company also reviews the LTV ratio of its commercial mortgage loan portfolio. LTV ratios compare the unpaid principal balance of the loan to the estimated fair value of the underlying collateral. Generally, the higher the LTV ratio, the higher the risk of experiencing a credit loss. The DSCR and the values utilized in calculating the ratio are updated routinely. In addition, the LTV ratio is routinely updated for all but the lowest risk loans as part of the Company’s ongoing review of its commercial mortgage loan portfolio.

For agricultural mortgage loans, the Company’s primary credit quality indicator is the LTV ratio. The values utilized in calculating this ratio are developed in connection with the ongoing review of the agricultural mortgage loan portfolio and are routinely updated.

Commitments to lend: After loans are approved, the Company makes commitments to lend and, typically, borrowers draw down on some or all of the commitments. The timing of mortgage loan funding is based on the commitment expiration dates. A liability for credit loss for unfunded commercial and agricultural mortgage loan commitments is recorded within net investment gains (losses). The liability is based on estimated lifetime loss rates as described above and the amount of the outstanding commitments, which for lines of credit, considers estimated utilization rates. When the commitment is funded or expires, the liability is adjusted accordingly.

The Company’s residential mortgage loan portfolio is comprised primarily of purchased closed end, amortizing residential mortgage loans, including both performing loans purchased within 12 months of origination and reperforming loans purchased after they have been performing for at least 12 months post-modification. Residential mortgage loans are pooled by loan type (i.e., new origination and reperforming) and pooled by similar risk profiles (including consumer credit score and LTV ratios). Estimated lifetime loss rates, which vary by loan type and risk profile, are applied to the amortized cost of each loan excluding accrued investment income on a quarterly basis to develop the ACL. The estimated lifetime loss rates are based on several factors, including (i) industry historical experience and expected results over the forecast period for defaults, (ii) loss severity, (iii) prepayment rates, (iv) current and forecasted economic conditions including growth, inflation, interest rates and unemployment levels, and (v) loan pool specific characteristics including consumer credit scores, LTV ratios, payment history and home prices. These evaluations are revised as conditions change and new information becomes available. The Company uses industry historical experience which captures multiple economic cycles as the Company has purchased most of its residential mortgage loans in the last five years. The Company uses a forecast of economic assumptions for a two-year period for most of its residential mortgage loans. After the applicable forecast period, the Company immediately reverts to industry historical loss experience.

For residential mortgage loans, the Company’s primary credit quality indicator is whether the loan is performing or nonperforming. The Company generally defines nonperforming residential mortgage loans as those that are 60 or more days past due and/or in nonaccrual status which is assessed monthly. Generally, nonperforming residential mortgage loans have a higher risk of experiencing a credit loss.

Mortgage Loan Concessions

In response to the adverse economic impact of the COVID-19 Pandemic, during 2020 the Company granted concessions to certain of its commercial, agricultural and residential mortgage loan borrowers, including payment deferrals and other loan modifications. The Company has elected the option under the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”), the Consolidated Appropriations Act, 2021 and the Interagency Statement on Loan Modifications and Reporting for Financial Institutions Working with Customers Affected by the Coronavirus (Revised) (“Interagency Statement”) issued by bank regulatory agencies, not to account for or report qualifying concessions as TDRs and not to classify such loans as either past due or nonaccrual during the payment deferral period. Additionally, in accordance with the FASB’s published response to a COVID-19 Pandemic technical inquiry, the Company continues to accrue interest income on such loans that have deferred payment. The Company records an ACL on this accrued interest income.

Commercial

For some commercial mortgage loan borrowers (principally in the retail and hotel sectors), the Company granted concessions which were primarily interest and principal payment deferrals generally ranging from three to four months and, to a much lesser extent, maturity date extensions. Deferred commercial mortgage loan interest and principal payments were $66 million at December 31, 2020.

Agricultural

For some agricultural mortgage loan borrowers (principally in the annual crops and agribusiness sectors), the Company granted concessions which were primarily principal payment deferrals generally ranging from three to 12 months, and covenant changes and, to a much lesser extent, maturity date extensions. Deferred agricultural mortgage loan interest and principal payments were $6 million at December 31, 2020.

Residential

For some residential mortgage loan borrowers, the Company granted concessions which were primarily three-month interest and principal payment deferrals. Deferred residential mortgage loan interest and principal payments were $37 million at December 31, 2020.

Troubled Debt Restructurings

The Company assesses loan concessions prior to the issuance of, or outside the scope of, the CARES Act, the Consolidated Appropriations Act, 2021 and the Interagency Statement on a case-by-case basis to evaluate whether a TDR has occurred. The Company may grant concessions to borrowers experiencing financial difficulties which, if not

significant, are not classified as TDRs, while more significant concessions are classified as TDRs. Generally, the types of concessions include: reduction of the contractual interest rate, extension of the maturity date at an interest rate lower than current market interest rates, and/or a reduction of accrued interest. The amount, timing and extent of the concessions granted are considered in determining any ACL recorded.

For both years ended December 31, 2020 and 2019, the Company did not have commercial mortgage loans modified in a troubled debt restructuring.

For the year ended December 31, 2020, the Company did not have a significant amount of agricultural mortgage loans modified in a troubled debt restructuring. For the year ended December 31, 2019, the Company had three agricultural mortgage loans modified in a troubled debt restructuring with carrying value of $111 million for both pre-modification and post-modification.

For the year ended December 31, 2020, the Company did not have a significant amount of residential mortgage loans modified in a troubled debt restructuring. For the year ended December 31, 2019, the Company had 396 residential mortgage loans modified in a troubled debt restructuring with carrying value of $97 million and $87 million pre-modification and post-modification, respectively.

For both years ended December 31, 2020 and 2019, the Company did not have a significant amount of mortgage loans modified in a troubled debt restructuring with subsequent payment default.

__________________

(1)Includes residential mortgage loans in process of foreclosure of $103 million and $118 million at December 31, 2020 and 2019, respectively.

LTV ratios compare the unpaid principal balance of the loan to the estimated fair value of the underlying collateral. At December 31, 2020, the amortized cost of commercial and agricultural mortgage loans with a LTV ratio in excess of 100% was $650 million, or less than 1% of total commercial and agricultural mortgage loans, however after considering the reduction in carrying value from the related ACL, no loans have a ratio greater than 100%.

Past Due and Nonaccrual Mortgage Loans

The Company has a high quality, well performing mortgage loan portfolio, with 99% of all mortgage loans classified as performing at both December 31, 2020 and 2019. The Company defines delinquency consistent with industry practice, when mortgage loans are past due more than two or more months, as applicable, by portfolio segment. The past due and nonaccrual mortgage loans at amortized cost, prior to ACL, by portfolio segment, were as follows:

	Past Due				Greater than 90 Days Past Due and Still Accruing Interest				Nonaccrual
Portfolio Segment	December 31, 2020		December 31, 2019		December 31, 2020		December 31, 2019		December 31, 2020		December 31, 2019
	(In millions)

Total	$	818	$	591	$	91	$	51	$	1,117	$	731

The amortized cost for nonaccrual commercial, agricultural and residential mortgage loans at beginning of year 2019 was $176 million, $105 million and $436 million, respectively. The amortized cost for nonaccrual commercial mortgage loans with no ACL was $168 million and $0 at December 31, 2020 and December 31, 2019, respectively. The amortized cost for nonaccrual agricultural mortgage loans with no ACL was $178 million and $93 million at December 31, 2020 and December 31, 2019, respectively. There were no nonaccrual residential mortgage loans without an ACL at either December 31, 2020 or December 31, 2019.

Purchased Investments with Credit Deterioration

Investments that, as of the date of acquisition, have experienced a more-than-insignificant deterioration in credit quality since origination are classified as PCD. The amortized cost for PCD investments is the purchase price plus an ACL for the initial estimate of expected lifetime credit losses established upon purchase. Subsequent changes in the ACL on PCD investments are recorded in net investment gains (losses). The non-credit discount or premium is accreted or amortized to net investment income on an effective yield basis.

The following table reconciles the contractual principal to the purchase price of PCD investments:

	Year Ended December 31, 2020
	Contractual Principal		ACL at Acquisition		Non-Credit (Discount) Premium		Purchase Price
	(In millions)
PCD residential mortgage loans	$	593	$	(18)	$	(13)	$	562

Prior to the adoption of new credit loss guidance for the recognition of credit losses on financial instruments, the Company applied applicable guidance for investments acquired with evidence of credit quality deterioration since origination, known as PCI investments. The Company’s PCI investments had an outstanding principal balance of $3.3 billion at December 31, 2019, which represents the contractually required principal and accrued interest payments whether or not currently due and a carrying value (estimated fair value of the investments plus accrued interest) of $2.7 billion at December 31, 2019. Accretion of accretable yield on PCI investments recognized in net investment income was $178 million and $275 million for the years ended December 31, 2019 and 2018, respectively.

Real Estate and Real Estate Joint Ventures

The Company’s real estate investment portfolio is diversified by property type, geography and income stream, including income from operating leases, operating income and equity in earnings from equity method real estate joint ventures. Real estate investments, by income type, as well as income earned, were as follows at and for the periods indicated:

	December 31, 2020		December 31, 2019		Years Ended December 31,
					2020		2019		2018
Income Type	Carrying Value				Income
	(In millions)
Leased real estate investments	$	5,450	$	4,893	$	435	$	380	$	399
Other real estate investments	419		420		133		192		188
Real estate joint ventures	6,064		5,428		(36)		104		107
Total real estate and real estate joint ventures	$	11,933	$	10,741	$	532	$	676	$	694

The carrying value of real estate investments acquired through foreclosure was $20 million and $36 million at December 31, 2020 and 2019, respectively. Depreciation expense on real estate investments was $123 million, $100 million and $92 million for the years ended December 31, 2020, 2019 and 2018, respectively. Real estate investments were net of accumulated depreciation of $1.1 billion and $957 million at December 31, 2020 and 2019, respectively.

As a result of the COVID-19 Pandemic, earnings from certain of the Company’s equity method real estate joint ventures were reduced for the year ended December 31, 2020, principally hotel properties. Certain of these real estate joint ventures have granted some lessees COVID-19 Pandemic-related lease concessions. See “— Leases — Lease Concessions.”

Leases

Leased Real Estate Investments - Operating Leases

The Company, as lessor, leases investment real estate, principally commercial real estate for office and retail use, through a variety of operating lease arrangements, which typically include tenant reimbursement for property operating costs and options to renew or extend the lease. In some circumstances, leases may include an option for the lessee to purchase the property. In addition, certain leases of retail space may stipulate that a portion of the income earned is contingent upon the level of the tenants’ revenues. The Company has elected a practical expedient of not separating non-lease components related to reimbursement of property operating costs from associated lease components. These property operating costs have the same timing and pattern of transfer as the related lease component, because they are incurred over the same period of time as the operating lease. Therefore, the combined component is accounted for as a single operating lease. Risk is managed through lessee credit analysis, property type diversification, and geographic diversification. Leased real estate investments and income earned, by property type, were as follows at and for the periods indicated:

	December 31, 2020		December 31, 2019		Years Ended December 31,
					2020		2019		2018
Property Type	Carrying Value				Income

Future contractual receipts under operating leases at December 31, 2020 were $331 million in 2021, $268 million in 2022, $230 million in 2023, $200 million in 2024, $180 million in 2025, $1.2 billion thereafter and, in total, are $2.4 billion.

Leveraged and Direct Financing Leases

The Company has diversified leveraged lease and direct financing lease portfolios. Its leveraged leases principally include renewable energy generation facilities, rail cars, commercial real estate and commercial aircraft, and its direct financing leases principally include commercial real estate. These assets are leased through a variety of lease arrangements, which may include options to renew or extend the lease and options for the lessee to purchase the property. Residual values are estimated using available third-party data at inception of the lease. Risk is managed through lessee credit analysis, asset allocation, geographic diversification, and ongoing reviews of estimated residual values, using available third-party data and, in certain leases, linking the amount of future rental receipts to changes in inflation rates. Generally, estimated residual values are not guaranteed by the lessee or a third party.

Investment in leveraged and direct financing leases consisted of the following at:

	December 31, 2020				December 31, 2019
	Leveraged Leases		Direct Financing Leases		Leveraged Leases		Direct Financing Leases

__________________

(1)Future contractual receipts under direct financing leases at December 31, 2020 were $27 million in 2021, $103 million in 2022, $112 million in 2023, $119 million in 2024, $102 million in 2025, $1.6 billion thereafter and, in total $2.1 billion.

Lease receivables are generally due in periodic installments. The payment periods for leveraged leases generally range from one to 11 years but in certain circumstances can be over 11 years, while the payment periods for direct financing leases generally range from one to 25 years but in certain circumstances can be over 25 years. For lease receivables, the

primary credit quality indicator is whether the lease receivable is performing or nonperforming, which is assessed monthly. The Company generally defines nonperforming lease receivables as those that are 90 days or more past due. At both December 31, 2020 and 2019, all leveraged lease receivables were performing. At December 31, 2020 and 2019, 96% and 94% of direct financing lease receivables were performing, respectively.

The deferred income tax liability related to leveraged leases was $287 million and $467 million at December 31, 2020 and 2019, respectively.

The components of income from investment in leveraged and direct financing leases, excluding net investment gains (losses), were as follows:

	Years Ended December 31,
	2020				2019				2018
	Leveraged Leases		Direct Financing Leases		Leveraged Leases		Direct Financing Leases		Leveraged Leases		Direct Financing Leases
	(In millions)

Lease investment income, net of income tax	$	31	$	84	$	38	$	86	$	37	$	75

In accordance with new credit loss guidance adopted January 1, 2020, the Company records an allowance for expected lifetime credit loss in an amount that represents the portion of the investment in leases that the Company does not expect to collect, resulting in the investment in leases being presented at the net amount expected to be collected. In determining the ACL, management: (i) pools leases that share similar risk characteristics, (ii) considers expected lifetime credit loss over the contractual term of the lease, and (iii) considers past events and current and forecasted economic conditions. Leases with dissimilar risk characteristics are evaluated individually for credit loss. Expected lifetime credit loss on leveraged lease receivables is estimated using a probability of default and loss given default model, where the probability of default incorporates third party credit ratings of the lessee and the related historical default data. Direct financing leases principally relate to leases of commercial real estate; accordingly, expected lifetime credit loss is estimated on such lease receivables consistent with the methodology for commercial mortgage loans (see “— Mortgage Loans — Allowance for Credit Loss Methodology”). The Company also assesses the non-guaranteed residual values for recoverability by comparison to the current estimated fair value of the leased asset and considers other relevant market information such as independent third-party forecasts, consulting, asset brokerage and investment banking reports and data, comparable market transactions, and factors such as the competitive dynamics impacting specific industries, technological change and obsolescence, government and regulatory rules, tax policy, potential environmental liabilities and litigation.

Prior to the adoption of the new credit loss guidance, lease impairment losses were recorded as incurred. Under the incurred loss model, if all amounts due under the lease agreement would not be collected based on current information and events, an impairment loss was recorded. The impairment loss was recorded as a reduction of the investment in lease and within net investment gains (losses).

Lease Concessions

In response to the adverse economic impact of the COVID-19 Pandemic, the Company granted concessions to certain of its lessees (operating and direct financing leases), primarily in the form of rent deferrals. In accordance with a Question and Answer document issued by the FASB in response to the COVID-19 Pandemic, the Company has elected not to evaluate whether such lease concessions are lease modifications, continues to accrue income on such leases and records rent receivables on real estate operating leases. The rent deferrals generally range from one to six months for operating leases and three to six months for commercial real estate direct financing leases. Deferred rental payments and rental abatements for both operating and direct financing leases were $15 million and $3 million, respectively, at December 31, 2020. The Company has interests in certain unconsolidated real estate joint ventures which have granted COVID-19 Pandemic-related lease concessions.

Other Invested Assets

Other invested assets is comprised primarily of freestanding derivatives with positive estimated fair values (see Note 9), tax credit and renewable energy partnerships, annuities funding structured settlement claims and direct financing and leveraged leases.

Tax Credit Partnerships

The carrying value of tax credit partnerships was $1.1 billion and $1.3 billion at December 31, 2020 and 2019, respectively. Losses from tax credit partnerships included within net investment income were $226 million, $240 million and $257 million for the years ended December 31, 2020, 2019 and 2018, respectively.

Cash Equivalents

The carrying value of cash equivalents, which includes securities and other investments with an original or remaining maturity of three months or less at the time of purchase, was $9.7 billion and $8.6 billion at December 31, 2020 and 2019, respectively.

Net Unrealized Investment Gains (Losses)

Unrealized investment gains (losses) on fixed maturity securities AFS and derivatives and the effect on DAC, VOBA, DSI, future policy benefits and the policyholder dividend obligation, that would result from the realization of the unrealized gains (losses), are included in net unrealized investment gains (losses) in AOCI.

(2)The Company is permitted to withdraw any portion of the pledged collateral over the minimum collateral requirement at any time, other than in the event of a default by the Company.

(3)Excludes assets held-for-sale at December 31, 2020. See Note 3 for information on the pending disposition of MetLife P&C.

If the Company is required to return significant amounts of cash collateral on short notice and is forced to sell securities to meet the return obligation, it may have difficulty selling such collateral that is invested in securities in a timely manner, be forced to sell securities in a volatile or illiquid market for less than what otherwise would have been realized under normal market conditions, or both.

The securities lending, repurchase agreements and FHLB of Boston short-term advance agreements reinvestment portfolios consist principally of high quality, liquid, publicly-traded fixed maturity securities AFS, short-term investments, cash equivalents or cash. If the securities on loan, securities pledged or the reinvestment portfolio become less liquid, liquidity resources within the general account are available to meet any potential cash demands when securities on loan or securities pledged are put back by the counterparty.

(1)    The Company has pledged invested assets in connection with various agreements and transactions, including funding agreements (see Note 4), derivative transactions (see Note 9), secured debt (see Note 13), and a collateral financing arrangement (see Note 14).

See “— Securities Lending, Repurchase Agreements and FHLB of Boston Advance Agreements” for information regarding securities supporting securities lending, repurchase agreement transactions and FHLB of Boston short-term advance agreements and Note 7 for information regarding investments designated to the closed block. In addition, the Company’s investment in FHLB common stock, which is considered restricted until redeemed by the issuers, was $814 million and $809 million, at redemption value, at December 31, 2020 and 2019, respectively.

Collectively Significant Equity Method Investments

The Company holds investments in real estate joint ventures, real estate funds and other limited partnership interests consisting of leveraged buy-out funds, hedge funds, private equity funds, joint ventures and other funds. The portion of these investments accounted for under the equity method had a carrying value of $17.9 billion at December 31, 2020. The Company’s maximum exposure to loss related to these equity method investments is limited to the carrying value of these investments plus unfunded commitments of $8.0 billion at December 31, 2020. Except for certain real estate joint ventures and certain funds, the Company’s investments in its remaining real estate funds and other limited partnership interests are generally of a passive nature in that the Company does not participate in the management of the entities.

As described in Note 1, the Company generally records its share of earnings in its equity method investments using a three-month lag methodology and within net investment income. Aggregate net investment income from these equity method investments exceeded 10% of the Company’s consolidated pre-tax income (loss) for two of the three most recent annual periods: 2020 and 2019.

The following aggregated summarized financial data reflects the latest available financial information and does not represent the Company’s proportionate share of the assets, liabilities, or earnings of such entities. Aggregate total assets of these entities totaled $704.5 billion and $585.3 billion at December 31, 2020 and 2019, respectively. Aggregate total liabilities of these entities totaled $99.4 billion and $86.1 billion at December 31, 2020 and 2019, respectively. Aggregate net income (loss) of these entities totaled $41.6 billion, $47.0 billion and $52.5 billion for the years ended December 31, 2020, 2019 and 2018, respectively. Aggregate net income (loss) from the underlying entities in which the Company invests is primarily comprised of investment income, including recurring investment income and realized and unrealized investment gains (losses).

Variable Interest Entities

The Company has invested in legal entities that are VIEs. In certain instances, the Company holds both the power to direct the most significant activities of the entity, as well as an economic interest in the entity and, as such, is deemed to be the primary beneficiary or consolidator of the entity. The determination of the VIE’s primary beneficiary requires an evaluation of the contractual and implied rights and obligations associated with each party’s relationship with or involvement in the entity, an estimate of the entity’s expected losses and expected residual returns and the allocation of such estimates to each party involved in the entity.

Consolidated VIEs

Creditors or beneficial interest holders of VIEs where the Company is the primary beneficiary have no recourse to the general credit of the Company, as the Company’s obligation to the VIEs is limited to the amount of its committed investment.

The following table presents the total assets and total liabilities relating to investment related VIEs for which the Company has concluded that it is the primary beneficiary and which are consolidated at:

	December 31,
	2020				2019
Asset Type	Total Assets (1)		Total Liabilities		Total Assets (1)		Total Liabilities
	(In millions)
Investment funds (1)	$	258	$	1	$	207	$	1
Renewable energy partnership (1)	87		—		94		—
Other investments (2)	4		5		10		5
Total	$	349	$	6	$	311	$	6

__________________

(1)    Assets of the investment funds and renewable energy partnership primarily consisted of other invested assets.

(2)    Assets of other investments primarily consisted of cash and cash equivalents at December 31, 2020 and other invested assets at December 31, 2019.

Unconsolidated VIEs

The carrying amount and maximum exposure to loss relating to VIEs in which the Company holds a significant variable interest but is not the primary beneficiary and which have not been consolidated were as follows at:

	December 31,
	2020				2019
Asset Type	Carrying Amount		Maximum Exposure to Loss (1)		Carrying Amount		Maximum Exposure to Loss (1)
	(In millions)
Fixed maturity securities AFS:
Structured Products (2)	$	56,962	$	56,962	$	51,962	$	51,962
U.S. and foreign corporate	3,011		3,011		1,764		1,764
Foreign government	142		142		136		136
Other limited partnership interests	8,355		14,911		6,674		12,016
Other invested assets	1,320		1,404		1,495		1,621
Other investments	619		639		450		497
Total	$	70,409	$	77,069	$	62,481	$	67,996

__________________

(1)The maximum exposure to loss relating to fixed maturity securities AFS is equal to their carrying amounts or the carrying amounts of retained interests. The maximum exposure to loss relating to other limited partnership interests is equal to the carrying amounts plus any unfunded commitments. For certain of its investments in other invested assets, the Company’s return is in the form of income tax credits which are guaranteed by creditworthy third parties. For such investments, the maximum exposure to loss is equal to the carrying amounts plus any unfunded commitments, reduced by income tax credits guaranteed by third parties of $3 million and $6 million at December 31, 2020 and 2019, respectively. Such a maximum loss would be expected to occur only upon bankruptcy of the issuer or investee.

(2)For these variable interests, the Company’s involvement is limited to that of a passive investor in mortgage-backed or asset-backed securities issued by trusts that do not have substantial equity.

As described in Note 21, the Company makes commitments to fund partnership investments in the normal course of business. Excluding these commitments, the Company did not provide financial or other support to investees designated as VIEs for each of the years ended December 31, 2020, 2019 and 2018.

The Company securitizes certain residential mortgage loans and acquires an interest in the related RMBS issued. While the Company has a variable interest in the issuer of the securities, it is not the primary beneficiary of the issuer of the securities since it does not have any rights to remove the servicer or veto rights over the servicer’s actions. The resulting gains (losses) from the securitizations are included within net investment gains (losses). The estimated fair value of the related RMBS acquired in connection with the securitizations is included in the carrying amount and maximum exposure to loss for Structured Products presented in the table above.

The carrying value and the estimated fair value of residential mortgage loans securitized were $308 million and $313 million, respectively, during 2020, and $443 million and $467 million, respectively, during 2019. Gains on securitizations of $5 million and $24 million for the years ended December 31, 2020 and 2019, respectively, were included within net investment gains (losses). The estimated fair value of RMBS acquired in connection with the securitizations was $43 million and $131 million at December 31, 2020 and 2019, respectively.

See Note 10 for information on how the estimated fair value of mortgage loans and RMBS is determined, the valuation approaches and key inputs, their placement in the fair value hierarchy, and for certain RMBS, quantitative information about the significant unobservable inputs and the sensitivity of their estimated fair value to changes in those inputs.
