The amortized cost and fair value of fixed maturities, including securities pledged, as of June 30, 2020, are shown below by contractual maturity. Actual maturities may differ from contractual maturities as securities may be restructured, called or prepaid. Mortgage-backed securities ("MBS") and Other asset-backed securities ("ABS") are shown separately because they are not due at a single maturity date.

The investment portfolio is monitored to maintain a diversified portfolio on an ongoing basis. Credit risk is mitigated by monitoring concentrations by issuer, sector and geographic stratification and limiting exposure to any one issuer. 

As of June 30, 2020 and December 31, 2019, the Company did not have any investments in a single issuer, other than obligations of the U.S. Government and government agencies, with a carrying value in excess of 10% of the Company's Total shareholder's equity.

The following tables present the composition of the U.S. and foreign corporate securities within the fixed maturity portfolio by industry category as of the dates indicated:

The Company has elected the FVO for certain of its fixed maturities to better match the measurement of assets and liabilities in the Condensed Consolidated Statements of Operations. Certain collateralized mortgage obligations ("CMOs"), primarily interest-only and principal-only strips, are accounted for as hybrid instruments and reported at fair value with changes in the fair value recorded in Other net realized capital gains (losses) in the Condensed Consolidated Statements of Operations.

The Company invests in various categories of CMOs, including CMOs that are not agency-backed, that are subject to different degrees of risk from changes in interest rates and defaults. The principal risks inherent in holding CMOs are prepayment and extension risks related to significant decreases and increases in interest rates resulting in the prepayment of principal from the underlying mortgages, either earlier or later than originally anticipated. As of June 30, 2020 and December 31, 2019, approximately 48.3% and 48.4%, respectively, of the Company’s CMO holdings, were invested in the above mentioned types of CMOs such as interest-only or principal-only strips, that are subject to more prepayment and extension risk than traditional CMOs.

Public corporate fixed maturity securities are distinguished from private corporate fixed maturity securities based upon the manner in which they are transacted. Public corporate fixed maturity securities are issued initially through market intermediaries on a registered basis or pursuant to Rule 144A under the Securities Act of 1933 (the "Securities Act") and are traded on the secondary market through brokers acting as principal. Private corporate fixed maturity securities are originally issued by borrowers directly to investors pursuant to Section 4(a)(2) of the Securities Act, and are traded in the secondary market directly with counterparties, either without the participation of a broker or in agency transactions.

Repurchase Agreements

As of June 30, 2020 and December 31, 2019, the Company did not have any securities pledged in dollar rolls, repurchase agreement transactions or reverse repurchase agreements.

Securities Lending

The Company engages in securities lending whereby the initial collateral is required at a rate of 102% of the market value of the loaned securities.  The lending agent retains the collateral and invests it in high quality liquid assets on behalf of the Company. The market value of the loaned securities is monitored on a daily basis with additional collateral obtained or refunded as the market value of the loaned securities fluctuates. The lending agent indemnifies the Company against losses resulting from the failure of a counterparty to return securities pledged where collateral is insufficient to cover the loss. As of June 30, 2020 and December 31, 2019, the fair value of loaned securities was $549 and $715, respectively, and is included in Securities pledged on the Condensed Consolidated Balance Sheets.

If cash is received as collateral, the lending agent retains the cash collateral and invests it in short-term liquid assets on behalf of the Company. As of June 30, 2020 and December 31, 2019, cash collateral retained by the lending agent and invested in short-term liquid assets on the Company's behalf was $489 and $650, respectively, and is recorded in Short-term investments under securities loan agreements, including collateral delivered on the Condensed Consolidated Balance Sheets. As of June 30, 2020 and December 31, 2019, liabilities to return collateral of $489 and $650, respectively, are included in Payables under securities loan agreements, including collateral held, on the Condensed Consolidated Balance Sheets.

The Company accepts non-cash collateral in the form of securities. The securities retained as collateral by the lending agent may not be sold or re-pledged, except in the event of default, and are not reflected on the Company’s Condensed Consolidated Balance Sheets. This collateral generally consists of U.S. Treasury, U.S. Government agency securities and MBS pools. As of June 30, 2020 and December 31, 2019, the fair value of securities retained as collateral by the lending agent on the Company’s behalf was $79 and $91, respectively.

The following table presents borrowings under securities lending transactions by asset class pledged as of the dates indicated:

	June 30, 2020 (1)(2)		December 31, 2019 (1)(2)
U.S. Treasuries	$	101	$	109
U.S. Government agencies and authorities	4		—
U.S. corporate public securities	272		447
Foreign corporate public securities and foreign governments	190		185
Equity Securities	1		—
Payables under securities loan agreements	$	568	$	741

⁽¹⁾ As of June 30, 2020 and December 31, 2019, borrowings under securities lending transactions include cash collateral of $489 and $650, respectively.

⁽²⁾ As of June 30, 2020 and December 31, 2019, borrowings under securities lending transactions include non-cash collateral of $79 and $91, respectively.

The Company's securities lending activities are conducted on an overnight basis, and all securities loaned can be recalled at any time. The Company does not offset assets and liabilities associated with its securities lending program.

Variable Interest Entities ("VIEs")

The Company holds certain VIEs for investment purposes. VIEs may be in the form of private placement securities, structured securities, securitization transactions or limited partnerships. The Company has reviewed each of its holdings and determined that consolidation of these investments in the Company’s financial statements is not required, as the Company is not the primary beneficiary, because the Company does not have both the power to direct the activities that most significantly impact the entity’s economic performance and the obligation or right to potentially significant losses or benefits, for any of its investments in VIEs. The Company did not provide any non-contractual financial support and its carrying value represents the Company’s exposure to loss. The carrying value of the investments in VIEs was $752 and $738 as of June 30, 2020 and December 31, 2019, respectively; these investments are included in Limited partnerships/corporations on the Condensed Consolidated Balance Sheets. Income and losses recognized on these investments are reported in Net investment income in the Condensed Consolidated Statements of Operations.

Securitizations

The Company invests in various tranches of securitization entities, including Residential mortgage-backed securities ("RMBS"), Commercial mortgage-backed securities ("CMBS") and ABS. Through its investments, the Company is not obligated to provide any financial or other support to these entities. Each of the RMBS, CMBS and ABS entities are thinly capitalized by design and considered VIEs. The Company's involvement with these entities is limited to that of a passive investor. The Company has no unilateral right to appoint or remove the servicer, special servicer or investment manager, which are generally viewed to have the power to direct the activities that most significantly impact the securitization entities' economic performance, in any of these entities, nor does the Company function in any of these roles. The Company, through its investments or other arrangements, does not have the obligation to absorb losses or the right to receive benefits from the entity that could potentially be significant to the entity. Therefore, the Company is not the primary beneficiary and does not consolidate any of the RMBS, CMBS and ABS entities in which it holds investments. These investments are accounted for as investments available-for-sale as described in the Fair Value Measurements Note to these Condensed Consolidated Financial Statements and unrealized capital gains (losses) on these securities are recorded directly in AOCI, except for certain RMBS that are accounted for under the FVO, for which changes in fair value are reflected in Other net realized capital gains (losses) in the Condensed Consolidated Statements of Operations. The Company’s maximum exposure to loss on these structured investments is limited to the amount of its investment.

The Company concluded that an allowance for credit losses was unnecessary for these securities because the unrealized losses are not credit related.

Unrealized capital losses (including noncredit impairments), along with the fair value of fixed maturity securities, including securities pledged, by market sector and duration were as follows as of December 31, 2019:

	Twelve Months or Less Below Amortized Cost				More Than Twelve Months Below Amortized Cost					Total
	Fair Value		Unrealized Capital Losses		Fair Value		Unrealized Capital Losses			Fair Value		Unrealized Capital Losses

Total number of securities in an unrealized loss position	289				278					567

*Less than $1.

Based on the Company's quarterly evaluation of its securities in a unrealized loss position, described below, the Company concluded that these securities were not impaired as of June 30, 2020. The Company does not intend to sell the investments and it is not more likely than not that the Company will be required to sell the investments before recovery of their amortized cost bases. See the Business, Basis of Presentation and Significant Accounting Policies Note to these Consolidated Financial Statements for the policy used to evaluate whether the investments are impaired.

Gross unrealized capital losses on fixed maturities, including securities pledged, increased $236 from $63 to $299 for the six months ended June 30, 2020. The increase in gross unrealized capital losses was primarily due to non-credit related market factors.

At June 30, 2020, $6 of the total $299 of gross unrealized losses were from 2 available-for-sale fixed maturity securities with an unrealized loss position of 20% or more of amortized cost for 12 months or greater.

Evaluating Securities for Impairments

The Company performs a regular evaluation, on a security-by-security basis, of its available-for-sale securities holdings, including fixed maturity securities in accordance with its impairment policy in order to evaluate whether such investments are impaired.

The following tables identify the Company's impairments included in the Condensed Consolidated Statements of Operations, excluding impairments included in Other comprehensive income (loss) by type for the periods indicated:

The Company may sell securities during the period in which fair value has declined below amortized cost for fixed maturities. In certain situations, new factors, including changes in the business environment, can change the Company’s previous intent to continue holding a security. Accordingly, these factors may lead the Company to record additional intent related capital losses.

For the three months ended June 30, 2020 intent impairments in the amount of $$24 were recorded on assets designated to be included in the reinsurance agreement associated with the Individual Life Transaction.

Troubled Debt Restructuring

The Company invests in high quality, well performing portfolios of commercial mortgage loans and private placements. Under certain circumstances, modifications are granted to these contracts. Each modification is evaluated as to whether a troubled debt restructuring has occurred. A modification is a troubled debt restructuring when the borrower is in financial difficulty and the creditor makes concessions. Generally, the types of concessions may include reducing the face amount or maturity amount of the debt as originally stated, reducing the contractual interest rate, extending the maturity date at an interest rate lower than current market interest rates and/or reducing accrued interest. The Company considers the amount, timing and extent of the concession granted in determining any impairment or changes in the specific credit allowance recorded in connection with the troubled debt restructuring. A credit allowance may have been recorded prior to the quarter when the loan is modified in a troubled debt restructuring. Accordingly, the carrying value (net of the allowance) before and after modification through a troubled debt restructuring may not change significantly, or may increase if the expected recovery is higher than the pre-modification recovery assessment. For the three and six months ended June 30, 2020, the Company did not have any new commercial mortgage loan or private placement troubled debt restructuring. For the three and six months ended June 30, 2019, the Company did not have any new commercial mortgage loan and had one new private placement troubled debt restructuring with a pre-modification cost basis of $74 and post-modification carrying value of $57.

For the three and six months ended June 30, 2020 and June 30, 2019, the Company did not have any commercial mortgage loans or private placements modified in a troubled debt restructuring with a subsequent payment default.

Mortgage Loans on Real Estate

The Company diversifies its commercial mortgage loan portfolio by geographic region and property type to reduce concentration risk. The Company manages risk when originating commercial mortgage loans by generally lending only up to 75% of the estimated fair value of the underlying real estate. Subsequently, the Company continuously evaluates mortgage loans based on relevant current information including a review of loan-specific performance, property characteristics and market trends. Loan performance is monitored on a loan specific basis through the review of submitted appraisals, operating statements, rent revenues and annual inspection reports, among other items. This review ensures properties are performing at a consistent and acceptable level to secure the debt. The components to evaluate debt service coverage are received and reviewed at least annually to determine the level of risk.

Loan-to-value ("LTV") and debt service coverage ("DSC") ratios are measures commonly used to assess the risk and quality of mortgage loans. The LTV ratio, calculated at time of origination, is expressed as a percentage of the amount of the loan relative to the value of the underlying property. A LTV ratio in excess of 100% indicates the unpaid loan amount exceeds the underlying collateral. The DSC ratio, based upon the most recently received financial statements, is expressed as a percentage of the amount of a property’s net income to its debt service payments. A DSC ratio of less than 1.0 indicates that a property’s operations do not generate sufficient income to cover debt payments. These ratios are utilized as part of the review process described above.

The following tables present commercial mortgage loans by year of origination and LTV ratio as of the dates indicated. The information is updated as of June 30, 2020 and December 31, 2019, respectively.
