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, 2019 and December 31, 2018, 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 shareholders' 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, 2019 and December 31, 2018, approximately 40.3% and 41.6%, 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, 2019 and December 31, 2018, the Company did not have any securities pledged in dollar rolls or reverse repurchase agreements. As of June 30, 2019, the carrying value of securities pledged and obligation to repay loans related to repurchase agreement transaction was $67, respectively, and included in Securities pledged and Payables under securities loan and repurchase agreements, including collateral held, respectively, on the Condensed Consolidated Balance Sheets. As of December 31, 2018, the carrying value of securities pledged and obligation to repay loans related to repurchase agreement transaction was $45 and $46, respectively. Securities pledged related to repurchase agreements are comprised of other asset-backed securities.

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, 2019 and December 31, 2018, the fair value of loaned securities was $1,707 and $1,635, 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, 2019 and December 31, 2018, cash collateral retained by the lending agent and invested in short-term liquid assets on the Company's behalf was $1,525 and $1,581, 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, 2019 and December 31, 2018, liabilities to return collateral of $1,525 and $1,581, respectively, are included in Payables under securities loan and repurchase 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, 2019 and December 31, 2018, the fair value of securities retained as collateral by the lending agent on the Company’s behalf was $238 and $111, respectively.

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

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 other-than-temporarily impaired as of June 30, 2019. 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.

On a quarterly basis, the Company evaluates its available-for-sale investment portfolio to determine whether there has been an other-than-temporary decline in fair value below the amortized cost basis. All available-for-sale securities with fair values less than amortized cost are included in the Company’s evaluation. Generally, for non-structured securities, management considers the estimated fair value as 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 consideration utilized in its overall impairment evaluation process, which incorporates available information and the company’s best estimate of scenario based outcomes regarding the specific security and issuer. The Company also considers quality and amount of any credit enhancement; the security's position within the capital structure of the issuer; fundamentals of the industry and geographic area in which the security issuer operates; and the overall macroeconomic conditions. For structured securities, such as non-agency RMBS, CMBS, and ABS, the Company evaluates other-than-temporary impairments based on actual and projected cash flows, after considering the quality and updated loan-to-value ratios, reflecting current home prices of the underlying collateral, forecasted loss severity, the payment priority in the tranche and any credit enhancement within the structure. In assessing credit impairment, the Company performs discounted cash flow analysis comparing the current amortized cost of a security to the present value of the expected future cash flows, including estimated defaults, and prepayments. The discount rate is generally the effective interest rate of the fixed maturity prior to the impairment.

See the Business, Basis of Presentation and Significant Accounting Policies Note to our Consolidated Financial Statements in Part II, Item 8. in our Annual Report on Form 10-K for the policy used to evaluate whether the investments are other-than-temporarily impaired.

Gross unrealized capital losses on fixed maturities, including securities pledged, decreased $883 from $1,084 to $201 for the six months ended June 30, 2019. The decrease in gross unrealized capital losses was primarily due to declining interest rates.

At June 30, 2019, $39 of the total $201 of gross unrealized losses were from 13 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 Other-Than-Temporary 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 other-than-temporarily impaired.

The following table identifies 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.

The following table presents the amount of credit impairments on fixed maturities for which a portion of the OTTI loss was recognized in Other comprehensive income (loss) and the corresponding changes in such amounts for the periods indicated:

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 valuation allowance recorded in connection with the troubled debt restructuring. A valuation 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 specific valuation 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, 2019, the Company did not have any new commercial mortgage loan troubled debt restructuring. For the three months ended June 30, 2019, the Company did not have any new private placement troubled debt restructuring. For the six months ended June 30, 2019, the Company had one new private placement troubled debt restructuring with a pre-modification cost basis of $124 and post-modification carrying value of $93. For the three and six months ended June 30, 2018, 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 and June 30, 2018, respectively, 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 credit quality, 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.

The following table summarizes the Company's investment in mortgage loans as of the dates indicated:

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 table presents the LTV and DSC ratios as of the dates indicated:

As of June 30, 2019 and December 31, 2018, the Company had $2 and $5, respectively, of investments in fixed maturities that did not produce net investment income. Fixed maturities are moved to a non-accrual status when the investment defaults.

Interest income on fixed maturities is recorded when earned using an effective yield method, giving effect to amortization of premiums and accretion of discounts. Such interest income is recorded in Net investment income in the Condensed Consolidated Statements of Operations.

Net Realized Capital Gains (Losses)

Net realized capital gains (losses) comprise the difference between the amortized cost of investments and proceeds from sale and redemption, as well as losses incurred due to the credit-related and intent-related other-than-temporary impairment of investments. Realized investment gains and losses are also primarily generated from changes in fair value of embedded derivatives within products and fixed maturities, changes in fair value of fixed maturities recorded at FVO and changes in fair value including accruals on derivative instruments, except for effective cash flow hedges. Net realized capital gains (losses) also include changes in fair value of equity securities. The cost of the investments on disposal is generally determined based on first-in-first-out ("FIFO") methodology.
