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 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 valuation allowances and impairments is highly subjective and is based upon periodic 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 and trading 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.

______________

The noncredit loss component of OTTI losses for CMBS was in an unrealized gain position of $1 million at December 31, 2014, due to increases in estimated fair value subsequent to initial recognition of noncredit losses on such securities. See also “— Net Unrealized Investment Gains (Losses).”
The Company held non-income producing fixed maturity securities with an estimated fair value of $64 million and $74 million with unrealized gains (losses) of $28 million and $23 million at December 31, 2014 and 2013, respectively.
Methodology for Amortization of Premium and Accretion of Discount on Structured Securities
Amortization of premium and accretion of discount on structured securities 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 single class and multi-class mortgage-backed and ABS are estimated using inputs obtained from third-party specialists and based on management’s knowledge of the current market. For credit-sensitive mortgage-backed and ABS and certain prepayment-sensitive securities, the effective yield is recalculated on a prospective basis. For all other mortgage-backed and ABS, the effective yield is recalculated on a retrospective basis.

Evaluation of AFS Securities for OTTI and Evaluating Temporarily Impaired AFS Securities
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 impairment evaluation process include, but are not limited to: (i) the length of time and the extent to which the estimated fair value has been below cost or amortized cost; (ii) the potential for impairments when the issuer is experiencing significant financial difficulties; (iii) the potential for impairments in an entire industry sector or sub-sector; (iv) the potential for impairments in certain economically depressed geographic locations; (v) the potential for impairments where the issuer, series of issuers or industry has suffered a catastrophic loss or has exhausted natural resources; (vi) with respect to fixed maturity securities, 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 securities, changes in forecasted cash flows after considering the 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) the potential for impairments due to weakening of foreign currencies on non-functional currency denominated fixed maturity securities that are near maturity; and (ix) other subjective factors, including concentrations and information obtained from regulators and rating agencies.
The methodology and significant inputs used to determine the amount of credit loss on fixed maturity securities 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 prior to impairment.
When determining collectability and the period over which value is expected to recover, the Company applies considerations utilized in its overall impairment 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 best estimates of likely scenario-based 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; 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 securities including, but not limited to: the quality of underlying collateral, expected prepayment speeds, current and forecasted loss severity, consideration of the payment terms of the underlying loans or assets backing a particular security, and the payment priority within the tranche structure of the security.
When determining the amount of the credit loss for U.S. and foreign corporate securities, foreign government securities and state and political subdivision securities, the estimated fair value is considered the recovery value when available information does not indicate that another value is more appropriate. When information is identified that indicates a recovery value other than estimated fair value, management considers in the determination of recovery value the same considerations utilized in its overall impairment evaluation process as described above, as well as any private and public sector programs to restructure such securities.
With respect to securities that have attributes of debt and equity (perpetual hybrid securities), consideration is given in the OTTI 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 and extended 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. When an OTTI loss has occurred, the OTTI loss is the entire difference between the perpetual hybrid security’s cost and its estimated fair value with a corresponding charge to earnings.
The cost or amortized cost of fixed maturity and equity securities is adjusted for OTTI in the period in which the determination is made. The Company does not change the revised cost basis for subsequent recoveries in value.
In periods subsequent to the recognition of OTTI on a fixed maturity security, the Company accounts 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 is accreted over the remaining term of the fixed maturity security in a prospective manner based on the amount and timing of estimated future cash flows.
Current Period Evaluation
Based on the Company’s current evaluation of its AFS securities in an unrealized loss position in accordance with its impairment policy, and the Company’s current intentions and assessments (as applicable to the type of security) about holding, selling and any requirements to sell these securities, the Company concluded that these securities were not other-than-temporarily impaired at December 31, 2014. Future OTTI will depend primarily on economic fundamentals, issuer performance (including changes in the present value of future cash flows expected to be collected), and changes in credit ratings, collateral valuation, interest rates and credit spreads. If economic fundamentals deteriorate or if there are adverse changes in the above factors, OTTI may be incurred in upcoming periods.
Gross unrealized losses on fixed maturity securities decreased $2.6 billion during the year ended December 31, 2014 from $4.6 billion to $2.0 billion. The decrease in gross unrealized losses for the year ended December 31, 2014, was primarily attributable to a decrease in interest rates, partially offset by widening credit spreads.
At December 31, 2014, $143 million of the total $2.0 billion of gross unrealized losses were from 51 fixed maturity securities with an unrealized loss position of 20% or more of amortized cost for six months or greater.
Investment Grade Fixed Maturity Securities
Of the $143 million of gross unrealized losses on fixed maturity securities with an unrealized loss of 20% or more of amortized cost for six months or greater, $61 million, or 43%, are related to gross unrealized losses on 25 investment grade fixed maturity securities. Unrealized losses on investment grade fixed maturity securities are principally related to widening credit spreads and, with respect to fixed-rate fixed maturity securities, rising interest rates since purchase.
Below Investment Grade Fixed Maturity Securities
Of the $143 million of gross unrealized losses on fixed maturity securities with an unrealized loss of 20% or more of amortized cost for six months or greater, $82 million, or 57%, were related to gross unrealized losses on 26 below investment grade fixed maturity securities. Unrealized losses on below investment grade fixed maturity securities are principally related to non-agency RMBS (primarily alternative residential mortgage loans), ABS (primarily foreign ABS) and foreign corporate securities (primarily financial services industry) and are the result of significantly wider credit spreads resulting from higher risk premiums since purchase, largely due to economic and market uncertainties including concerns over valuations of residential real estate supporting non-agency RMBS. Management evaluates non-agency RMBS and ABS based on actual and projected cash flows after considering the 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; and evaluates foreign corporate securities based on factors such as expected cash flows and the financial condition and near-term and long-term prospects of the issuer.
Equity Securities
Gross unrealized losses on equity securities decreased $50 million during the year ended December 31, 2014 from $117 million to $67 million. Of the $67 million, $27 million were from six equity securities with gross unrealized losses of 20% or more of cost for 12 months or greater, all of which were financial services industry investment grade non-redeemable preferred stock, of which 22% were rated A or better.

Valuation Allowance Methodology
Mortgage loans are considered to be impaired when it is probable that, based upon current information and events, the Company will be unable to collect all amounts due under the loan agreement. Specific valuation allowances are established using the same methodology for all three portfolio segments as the excess carrying value of a loan over either (i) the present value of expected future cash flows discounted at the loan’s original effective interest rate, (ii) the estimated fair value of the loan’s underlying collateral if the loan is in the process of foreclosure or otherwise collateral dependent, or (iii) the loan’s observable market price. A common evaluation framework is used for establishing non-specific valuation allowances for all loan portfolio segments; however, a separate non-specific valuation allowance is calculated and maintained for each loan portfolio segment that is based on inputs unique to each loan portfolio segment. Non-specific valuation allowances are established for pools of loans with similar risk characteristics where a property-specific or market-specific risk has not been identified, but for which the Company expects to incur a credit loss. These evaluations are based upon several loan portfolio segment-specific factors, including the Company’s experience for loan losses, defaults and loss severity, and loss expectations for loans with similar risk characteristics. These evaluations are revised as conditions change and new information becomes available.
Commercial and Agricultural Mortgage Loan Portfolio Segments
The Company typically uses several years of historical experience in establishing non-specific valuation allowances which captures multiple economic cycles. 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, and recent loss and recovery trend experience as compared to historical loss and recovery 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. On a quarterly basis, management incorporates the impact of these current market events and conditions on historical experience in determining the non-specific valuation allowance established for commercial and agricultural mortgage loans.
All commercial mortgage loans are reviewed on an ongoing basis which may include an analysis of the property financial statements and rent roll, lease rollover analysis, property inspections, market analysis, estimated valuations of the underlying collateral, loan-to-value ratios, debt service coverage ratios, 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 loan-to-value ratios and lower debt service coverage ratios. All agricultural mortgage loans are monitored on an ongoing basis. The monitoring process for agricultural mortgage loans is generally similar to the commercial mortgage loan monitoring process, with a focus on higher risk loans, including reviews on a geographic and property-type basis. Higher risk loans are reviewed individually on an ongoing basis for potential credit loss and specific valuation allowances are established using the methodology described above. Quarterly, the remaining loans are reviewed on a pool basis by aggregating groups of loans that have similar risk characteristics for potential credit loss, and non-specific valuation allowances are established as described above using inputs that are unique to each segment of the loan portfolio.
For commercial mortgage loans, the primary credit quality indicator is the debt service coverage ratio, 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 debt service coverage ratio, the higher the risk of experiencing a credit loss. The Company also reviews the loan-to-value ratio of its commercial mortgage loan portfolio. Loan-to-value ratios compare the unpaid principal balance of the loan to the estimated fair value of the underlying collateral. Generally, the higher the loan-to-value ratio, the higher the risk of experiencing a credit loss. The debt service coverage ratio and loan-to-value ratio, as well as the values utilized in calculating these ratios, are updated annually, on a rolling basis, with a portion of the loan portfolio updated each quarter.
For agricultural mortgage loans, the Company’s primary credit quality indicator is the loan-to-value 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.
Residential Mortgage Loan Portfolio Segment
The Company’s residential mortgage loan portfolio is comprised primarily of closed end, amortizing residential mortgage loans. For evaluations of residential mortgage loans, the key inputs of expected frequency and expected loss reflect current market conditions, with expected frequency adjusted, when appropriate, for differences from market conditions and the Company’s historical experience. In contrast to the commercial and agricultural mortgage loan portfolios, residential mortgage loans are smaller-balance homogeneous loans that are collectively evaluated for impairment. Non-specific valuation allowances are established using the evaluation framework described above for pools of loans with similar risk characteristics from inputs that are unique to the residential segment of the loan portfolio. Loan specific valuation allowances are only established on residential mortgage loans when they have been restructured and are established using the methodology described above for all loan portfolio segments.
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 non-accrual status which is assessed monthly. Generally, nonperforming residential mortgage loans have a higher risk of experiencing a credit loss.

Mortgage Loans Modified in a Troubled Debt Restructuring
For a small portion of the mortgage loan portfolio, classified as troubled debt restructurings, concessions are granted related to borrowers experiencing financial difficulties. 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 concession granted is considered in determining any impairment or changes in the specific valuation allowance. During the years ended December 31, 2014 and 2013, the Company did not have a significant amount of mortgage loans modified in a troubled debt restructuring.
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, and leveraged and direct financing leases.

Rental receivables are generally due in periodic installments. The payment periods for leveraged leases generally range from one to 15 years but in certain circumstances can be over 30 years, while the payment periods for direct financing leases range from one to 30 years. For rental receivables, the primary credit quality indicator is whether the rental receivable is performing or nonperforming, which is assessed monthly. The Company generally defines nonperforming rental receivables as those that are 90 days or more past due. At December 31, 2014 and 2013, all leveraged lease receivables were performing and over 99% of direct financing rental receivables were performing.
The deferred income tax liability related to leveraged leases was $1.5 billion and $1.6 billion at December 31, 2014 and 2013, respectively.

In November 2014, MetLife Insurance Company of Connecticut (“MICC”), a wholly-owned subsidiary of MetLife, Inc., re-domesticated from Connecticut to Delaware, changed its name to MetLife Insurance Company USA and merged with its subsidiary, MetLife Investors USA Insurance Company (“MLI-USA”), and its affiliate, MetLife Investors Insurance Company (“MLIIC”), each a U.S. insurance company that issued variable annuity products in addition to other products, and Exeter Reassurance Company, Ltd. (“Exeter”), a former offshore reinsurance subsidiary of MetLife, Inc. and affiliate of MICC that mainly reinsured guarantees associated with variable annuity products (the “Mergers”). The surviving entity of the Mergers was MetLife Insurance Company USA (“MetLife USA”). Exeter, formerly a Cayman Islands company, was re-domesticated to Delaware in October 2013. In anticipation of the Mergers, effective January 1, 2014, following receipt of New York State Department of Financial Services (the “Department of Financial Services”) approval, MICC withdrew its license to issue insurance policies and annuity contracts in New York. Also effective January 1, 2014, MICC reinsured with an affiliate all existing New York insurance policies and annuity contracts that include a separate account feature and deposited investments with an estimated fair market value of $6.3 billion into a custodial account to secure MICC’s remaining New York policyholder liabilities not covered by such reinsurance.

The Company has pledged invested assets in connection with various agreements and transactions, including funding agreements (see Notes 4 and 12), collateral financing arrangements (see Note 13) and derivative transactions (see Note 9).
See “— Securities Lending” for information regarding securities on loan and Note 7 for information regarding investments designated to the closed block.
Purchased Credit Impaired Investments
Investments acquired with evidence of credit quality deterioration since origination and for which it is probable at the acquisition date that the Company will be unable to collect all contractually required payments are classified as purchased credit impaired (“PCI”) investments. For each investment, the excess of the cash flows expected to be collected as of the acquisition date over its acquisition date fair value is referred to as the accretable yield and is recognized as net investment income on an effective yield basis. If, subsequently, based on current information and events, it is probable that there is a significant increase in cash flows previously expected to be collected or if actual cash flows are significantly greater than cash flows previously expected to be collected, the accretable yield is adjusted prospectively. The excess of the contractually required payments (including interest) as of the acquisition date over the cash flows expected to be collected as of the acquisition date is referred to as the nonaccretable difference, and this amount is not expected to be realized as net investment income. Decreases in cash flows expected to be collected can result in OTTI or the recognition of mortgage loan valuation allowances.

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 $14.3 billion at December 31, 2014. 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 $4.1 billion at December 31, 2014. Except for certain real estate joint ventures, the Company’s investments in 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) from continuing operations for two of the three most recent annual periods: 2013 and 2012. The Company is providing the following aggregated summarized financial data for such equity method investments, for the most recent annual periods, in order to provide comparative information. This aggregated summarized financial data does not represent the Company’s proportionate share of the assets, liabilities, or earnings of such entities.
The aggregated summarized financial data presented below reflects the latest available financial information and is as of, and for, the years ended December 31, 2014, 2013 and 2012. Aggregate total assets of these entities totaled $385.7 billion and $303.4 billion at December 31, 2014 and 2013, respectively. Aggregate total liabilities of these entities totaled $39.5 billion and $29.7 billion at December 31, 2014 and 2013, respectively. Aggregate net income (loss) of these entities totaled $34.9 billion, $26.3 billion and $17.9 billion for the years ended December 31, 2014, 2013 and 2012, 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 certain structured transactions (including CSEs), formed trusts to invest proceeds from certain collateral financing arrangements and has insurance operations 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. The Company generally uses a qualitative approach to determine whether it is the primary beneficiary. However, for VIEs that are investment companies or apply measurement principles consistent with those utilized by investment companies, the primary beneficiary is based on a risks and rewards model and is defined as the entity that will absorb a majority of a VIE’s expected losses, receive a majority of a VIE’s expected residual returns if no single entity absorbs a majority of expected losses, or both. The Company reassesses its involvement with VIEs on a quarterly basis. The use of different methodologies, assumptions and inputs in the determination of the primary beneficiary could have a material effect on the amounts presented within the consolidated financial statements.
Consolidated VIEs
The following table presents the total assets and total liabilities relating to VIEs for which the Company has concluded that it is the primary beneficiary and which are consolidated at December 31, 2014 and 2013. 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.

______________
(1)
See Note 13 for a description of the MetLife Reinsurance Company of South Carolina (“MRSC”) collateral financing arrangement.
(2)
Assets of the operating joint venture are primarily fixed maturity securities and separate account assets. Liabilities of the operating joint venture are primarily future policy benefits, other policyholder funds and separate account liabilities.
(3)
The Company consolidates entities that are structured as CMBS and as collateralized debt obligations. The assets of these entities can only be used to settle their respective liabilities, and under no circumstances is the Company liable for any principal or interest shortfalls should any arise. The Company’s exposure was limited to that of its remaining investment in these entities of $123 million and $154 million at estimated fair value at December 31, 2014 and 2013, respectively. The long-term debt bears interest primarily at fixed rates ranging from 2.25% to 5.57%, payable primarily on a monthly basis. Interest expense related to these obligations, included in other expenses, was $38 million, $122 million and $163 million for the years ended December 31, 2014, 2013 and 2012 respectively.
(4)
At December 31, 2013, the Company consolidated an open ended core real estate fund formed in the fourth quarter of 2013 (the “MetLife Core Property Fund”), which represented the majority of the balances at December 31, 2013. As a result of the quarterly reassessment in the first quarter of 2014, the Company no longer consolidated the MetLife Core Property Fund, effective March 31, 2014, based on the terms of the revised partnership agreement. The Company accounts for its retained interest in the real estate fund under the equity method. Assets of the real estate fund are a real estate investment trust which holds primarily traditional core income-producing real estate which has associated liabilities that are primarily non-recourse debt secured by certain real estate assets of the fund. The assets of these entities can only be used to settle their respective liabilities, and under no circumstances is the Company liable for any principal or interest shortfalls should any arise. The Company’s exposure was limited to that of its investment in the real estate fund of $178 million at carrying value at December 31, 2013. The long-term debt bears interest primarily at fixed rates ranging from 1.39% to 4.45%, payable primarily on a monthly basis.
Unconsolidated VIEs

______________
(1)
The maximum exposure to loss relating to fixed maturity securities AFS, FVO and trading securities and equity 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, mortgage loans and real estate joint ventures is equal to the carrying amounts plus any unfunded commitments of the Company. 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 $212 million and $257 million at December 31, 2014 and 2013, 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 during the years ended December 31, 2014, 2013 and 2012.
