(1) The noncredit loss component of other-than-temporary impairment (“OTTI”) losses for CMBS was in an unrealized gain position of $1 million at both June 30, 2016 and December 31, 2015, 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 $115 million and $54 million with unrealized gains (losses) of $6 million and $12 million at June 30, 2016 and December 31, 2015, respectively.

Evaluation of AFS Securities for OTTI and Evaluating Temporarily Impaired AFS Securities

As described more fully in Notes 1 and 8 of the Notes to the Consolidated Financial Statements included in the 2015 Annual Report, the Company performs a regular evaluation of all investment classes for impairment, including fixed maturity securities, equity securities and perpetual hybrid securities, in accordance with its impairment policy, in order to evaluate whether such investments are other-than-temporarily impaired.

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 June 30, 2016. Future OTTI 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, 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$2.0 billionduring thesix months endedJune 30, 2016to$3.4 billion. The decrease in gross unrealized losses for thesix months endedJune 30, 2016was primarily attributable to a decrease in interest rates and, to a lesser extent, narrowing credit spreads and the impact of strengthening foreign currencies on non-functional currency denominated fixed maturity securities.

At June 30, 2016, $418 million of the total $3.4 billion of gross unrealized losses were from 129 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 $418 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, $228 million, or 55%, were related to gross unrealized losses on 60 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 $418 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, $190 million, or 45%, were related to gross unrealized losses on 69 below investment grade fixed maturity securities. Unrealized losses on below investment grade fixed maturity securities are principally related to U.S. and foreign corporate securities (primarily industrial securities) 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 lower oil prices in the energy sector. Management evaluates U.S. and foreign corporate securities based on factors such as expected cash flows and the financial condition and near-term and long-term prospects of the issuers.

Equity Securities

Gross unrealized losses on equity securities decreased $76 million during the six months endedJune 30, 2016 to $82 million. Of the $82 million, $49 million were from seven securities with gross unrealized losses of 20% or more of cost for 12 months or greater. Of the $49 million, 63% were rated A or better, and all were from financial services industry investment grade non-redeemable preferred stock.

(1) The related loaned security could be returned to the Company on the next business day which would require the Company to immediately return the cash collateral.

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 estimated fair value of the securities on loan related to the cash collateral on open at June 30, 2016 was $8.2 billion, over 99% of which were U.S. government and agency securities which, if put back to the Company, could be immediately sold to satisfy the cash requirement.

The reinvestment portfolio acquired with the cash collateral consisted principally of fixed maturity securities (including U.S. government and agency, agency RMBS, ABS, short-term investments and U.S. corporate securities) with 65% invested in U.S. government and agency securities, agency RMBS, short-term investments, or held in cash and cash equivalents. If the securities on loan or the reinvestment portfolio become less liquid, the Company has the liquidity resources of most of its general account available to meet any potential cash demands when securities on loan are put back to the Company.

Repurchase Agreement Transactions

The Company participates in short-term repurchase agreements and reverse repurchase agreements with unaffiliated financial institutions. Under these agreements, the Company lends fixed maturity securities and contemporaneously borrows other fixed maturity securities (e.g., repurchase and reverse repurchase, respectively). The Company obtains cash collateral in an amount greater than or equal to 95% of the estimated fair value of the securities loaned, and pledges cash collateral in an amount generally equal to 98% of the estimated fair value of the borrowed securities at the inception of the transaction. The Company monitors the estimated fair value of the securities loaned and borrowed on a daily basis with additional collateral obtained as necessary throughout the duration of the transaction.

The Company accounted for these transactions as collateralized borrowing and lending. The amount of fixed maturity securities lent and borrowed, at estimated fair value, was $320 million and $308 million, respectively, at June 30, 2016. There were no such transactions outstanding as of December 31, 2015. Securities loaned under such transactions may be sold or re-pledged by the transferee. Securities borrowed under such transactions may be re-pledged and are not reflected on the consolidated financial statements. The amount of borrowed securities which were re-pledged was $106 million, at estimated fair value, at June 30, 2016.

The Company has elected to offset amounts recognized as receivables and payables resulting from these transactions. The gross amounts of the receivables and payables related to these transactions at June 30, 2016 were both $300 million. After the effect of offsetting of $300 million, the net amount presented on the consolidated balance sheet at June 30, 2016 was a liability of less than $1 million. Amounts owed to and due from counterparties may be settled in cash or offset, in accordance with the agreements. Cash inflows and outflows for cash settlements are reported on the consolidated statements of cash flows. At June 30, 2016, all $300 million of payables from repurchase agreements had a remaining tenor of one to six months and were loans of U.S. and foreign corporate securities.

See Note 7 for information regarding the estimated fair value of the Company’s net derivative assets and net derivative liabilities after the application of master netting agreements and collateral.

Variable Interest Entities

The Company is involved with certain 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.

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 VIEs for which the Company has concluded that it is the primary beneficiary and which are consolidated at June 30, 2016 and December 31, 2015.

(2) Following a change in the foreign investment law in India, the Company no longer consolidated its India operating joint venture, effective January 1, 2016. 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 policy-related balances 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$106 millionand$105 millionat estimated fair value atJune 30, 2016andDecember 31, 2015, respectively. The long-term debt bears interest primarily at fixed rates ranging from2.25%to5.57%, payable primarily on a monthly basis. Interest expense related to these obligations, included in other expenses, was$2 millionand$3 millionfor thethree monthsandsix months endedJune 30, 2016, respectively, and$1 millionand$2 millionfor thethree monthsandsix months endedJune 30, 2015, respectively.

(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. 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 $162 million and $179 million at June 30, 2016 and December 31, 2015, respectively. Such a maximum loss would be expected to occur only upon bankruptcy of the issuer or investee.

FVO and trading securities are primarily comprised of securities for which the FVO has been elected (“FVO securities”). FVO securities include certain fixed maturity and equity securities held-for-investment by the general account to support asset and liability management strategies for certain insurance products and investments in certain separate accounts. FVO securities are primarily comprised of contractholder-directed investments supporting unit-linked variable annuity type liabilities which do not qualify for presentation as separate account summary total assets and liabilities. The investment returns on these investments inure to the contractholders and are offset by a corresponding change in policyholder account balances through interest credited to policyholder account balances. FVO securities also include securities held by CSEs. The Company previously maintained a trading securities portfolio, principally invested in fixed maturity securities, to support investment strategies that involved the active and frequent purchase and sale of actively traded securities and the execution of short sale agreements. In June 2016, the Company commenced a reinvestment of this portfolio into other asset classes.
