Investments with fair values less than amortized cost are included in the Company's other-than-temporary impairments analysis. Impairments were recognized as disclosed in the “Evaluating Securities for Other-Than-Temporary Impairments” section below. The Company evaluates non-agency RMBS and ABS for "other-than-temporary impairments" each quarter based on actual and projected cash flows, after considering the quality and updated loan-to-value ratios reflecting current home prices of underlying collateral, forecasted loss severity, the payment priority within the tranche structure of the security and amount of any credit enhancements. The Company's assessment of current levels of cash flows compared to estimated cash flows at the time the securities were acquired (typically pre-2008) indicates the amount and the pace of projected cash flows from the underlying collateral has generally been lower and slower, respectively. However, since cash flows are typically projected at a trust level, the impairment review incorporates the security's position within the trust structure as well as credit enhancement remaining in the trust to determine whether an impairment is warranted. Therefore, while lower and slower cash flows will impact the trust, the effect on the valuation of a particular security within the trust will also be dependent upon the trust structure. Where the assessment continues to project full recovery of principal and interest on schedule, the Company has not recorded an impairment. Based on this analysis, the Company determined that the remaining investments in an unrealized loss position were not other-than-temporarily impaired and therefore no further other-than-temporary impairment was necessary. 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 six months ended June 30, 2015 , the Company had no new troubled debt restructurings for private placement bonds or commercial mortgage loans. For the year ended December 31, 2014 , the Company had no new troubled debt restructurings for private placement bonds and one new troubled debt restructuring for commercial mortgage loans with a pre-modification and post-modification carrying value of $1.9 . As of June 30, 2015 , the Company held 13 commercial mortgage troubled debt restructured loans with a carrying value of $37.5 . Of these 13 loans, 12 were restructured in August 2013 with a pre-modification and post modification carrying value of $60.0 . These loans represent what remains of an initial portfolio of 20 restructures with a pre-modification and post modification carrying value of $88.6 . This portfolio of loans is comprised of cross-defaulted, cross-collateralized individual loans, which are owned by the same sponsor. Between the date of the troubled debt restructurings and June 30, 2015 , this portfolio of loans has repaid $53.3 in principal. As of June 30, 2015 and December 31, 2014 , the Company did no t 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's mortgage loans on real estate are all commercial mortgage loans held for investment, which are reported at amortized cost, less impairment write-downs and allowance for losses. 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 Company's policy is to recognize interest income until a loan becomes 90 days delinquent or foreclosure proceedings are commenced, at which point interest accrual is discontinued. Interest accrual is not resumed until the loan is brought current. There were no mortgage loans in the Company's portfolio in process of foreclosure or in arrears with respect to principal and interest as of June 30, 2015 and December 31, 2014 . The following tables present information on the average investment during the period in impaired loans and interest income recognized on impaired and troubled debt restructured loans for the periods indicated: Three Months Ended June 30, 2015 2014 Impaired loans, average investment during the period (amortized cost) (1) $ 44.5 $ 88.8 Interest income recognized on impaired loans, on an accrual basis (1) 0.7 1.2 Interest income recognized on impaired loans, on a cash basis (1) 0.7 1.2 Interest income recognized on troubled debt restructured loans, on an accrual basis 0.5 1.0 Six Months Ended June 30, 2015 2014 Impaired loans, average investment during the period (amortized cost) (1) $ 57.6 $ 88.9 Interest income recognized on impaired loans, on an accrual basis (1) 1.6 2.5 Interest income recognized on impaired loans, on a cash basis (1) 1.7 2.2 Interest income recognized on troubled debt restructured loans, on an accrual basis 1.3 2.2 (1) Includes amounts for Troubled debt restructured loans. 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 set forth the composition of the U.S. and foreign corporate securities within the fixed maturity portfolio by industry category as of the dates indicated: Amortized Cost Gross Unrealized Capital Gains Gross Unrealized Capital Losses Fair Value June 30, 2015 Communications $ 3,947.5 $ 317.0 $ 37.0 $ 4,227.5 Financial 7,643.0 526.6 45.8 8,123.8 Industrial and other companies 31,596.3 1,496.4 483.2 32,609.5 Utilities 8,645.3 600.0 80.1 9,165.2 Transportation 1,602.2 98.7 22.2 1,678.7 Total $ 53,434.3 $ 3,038.7 $ 668.3 $ 55,804.7 December 31, 2014 Communications $ 3,934.5 $ 512.4 $ 5.7 $ 4,441.2 Financial 7,568.1 729.3 7.6 8,289.8 Industrial and other companies 30,055.8 2,109.3 231.0 31,934.1 Utilities 9,046.3 959.9 19.7 9,986.5 Transportation 1,494.1 151.9 3.9 1,642.1 Total $ 52,098.8 $ 4,462.8 $ 267.9 $ 56,293.7 Fixed Maturities and Equity Securities The Company's fixed maturities and equity securities are currently designated as available-for-sale, except those accounted for using the FVO. Available-for-sale securities are reported at fair value and unrealized capital gains (losses) on these securities are recorded directly in Accumulated other comprehensive income (loss) (“AOCI”) and presented net of related changes in Deferred policy acquisition costs (“DAC”), Value of business acquired (“VOBA”) and Deferred income taxes. In addition, certain fixed maturities have embedded derivatives, which are reported with the host contract on the Condensed Consolidated Balance Sheets. 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 valued 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, 2015 and December 31, 2014 , approximately 46.9% and 44.4% , respectively, of the Company's CMO holdings, such as interest-only or principal-only strips, were invested in those types of CMOs 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 The Company engages in dollar repurchase agreements with mortgage-backed securities ("dollar rolls") and repurchase agreements with other collateral types to increase its return on investments and improve liquidity. Such arrangements meet the requirements to be accounted for as financing arrangements. The Company also enters into reverse repurchase agreements. These transactions involve a purchase of securities and an agreement to sell substantially the same securities as those purchased. As of June 30, 2015 and December 31, 2014 , the Company did no t have any securities pledged in dollar rolls, repurchase agreement transactions or reverse repurchase agreements. Securities Lending The Company engages in securities lending whereby certain securities from its portfolio are loaned to other institutions, through a lending agent, for short periods of time. The Company has the right to approve any institution with whom the lending agent transacts on its behalf. Initial collateral, primarily cash, 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 short-term 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, 2015 and December 31, 2014 , the fair value of loaned securities was $396.8 and $545.9 , respectively, and is included in Securities pledged on the Condensed Consolidated Balance Sheets. As of June 30, 2015 and December 31, 2014 , collateral retained by the lending agent and invested in short-term liquid assets on the Company's behalf was $413.2 and $563.9 , 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, 2015 and December 31, 2014 , liabilities to return collateral of $413.2 and $563.9 , respectively, is included in Payables under securities loan agreements, including collateral held on the Condensed Consolidated Balance Sheets. The following table sets forth borrowings under securities lending transactions by class of collateral pledged for the dates indicated: June 30, 2015 December 31, 2014 U.S. Treasuries $ — $ 205.4 U.S. Government agencies and authorities — 17.3 U.S. corporate public securities 226.9 216.7 Foreign corporate public securities and foreign governments 186.3 124.5 Payables under securities loan agreements $ 413.2 $ 563.9 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.

Investments with fair values less than amortized cost are included in the Company's other-than-temporary impairments analysis. Impairments were recognized as disclosed in the “Evaluating Securities for Other-Than-Temporary Impairments” section below. The Company evaluates non-agency RMBS and ABS for "other-than-temporary impairments" each quarter based on actual and projected cash flows, after considering the quality and updated loan-to-value ratios reflecting current home prices of underlying collateral, forecasted loss severity, the payment priority within the tranche structure of the security and amount of any credit enhancements. The Company's assessment of current levels of cash flows compared to estimated cash flows at the time the securities were acquired (typically pre-2008) indicates the amount and the pace of projected cash flows from the underlying collateral has generally been lower and slower, respectively. However, since cash flows are typically projected at a trust level, the impairment review incorporates the security's position within the trust structure as well as credit enhancement remaining in the trust to determine whether an impairment is warranted. Therefore, while lower and slower cash flows will impact the trust, the effect on the valuation of a particular security within the trust will also be dependent upon the trust structure. Where the assessment continues to project full recovery of principal and interest on schedule, the Company has not recorded an impairment. Based on this analysis, the Company determined that the remaining investments in an unrealized loss position were not other-than-temporarily impaired and therefore no further other-than-temporary impairment was necessary. 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 six months ended June 30, 2015 , the Company had no new troubled debt restructurings for private placement bonds or commercial mortgage loans. For the year ended December 31, 2014 , the Company had no new troubled debt restructurings for private placement bonds and one new troubled debt restructuring for commercial mortgage loans with a pre-modification and post-modification carrying value of $1.9 . As of June 30, 2015 , the Company held 13 commercial mortgage troubled debt restructured loans with a carrying value of $37.5 . Of these 13 loans, 12 were restructured in August 2013 with a pre-modification and post modification carrying value of $60.0 . These loans represent what remains of an initial portfolio of 20 restructures with a pre-modification and post modification carrying value of $88.6 . This portfolio of loans is comprised of cross-defaulted, cross-collateralized individual loans, which are owned by the same sponsor. Between the date of the troubled debt restructurings and June 30, 2015 , this portfolio of loans has repaid $53.3 in principal. As of June 30, 2015 and December 31, 2014 , the Company did no t 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's mortgage loans on real estate are all commercial mortgage loans held for investment, which are reported at amortized cost, less impairment write-downs and allowance for losses. 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: June 30, 2015 December 31, 2014 Commercial mortgage loans $ 10,369.5 $ 9,796.9 Collective valuation allowance for losses (2.8 ) (2.8 ) Total net commercial mortgage loans $ 10,366.7 $ 9,794.1 There were no impairments taken on the mortgage loan portfolio for the three and six months ended June 30, 2015 and 2014 .

The Company's policy is to recognize interest income until a loan becomes 90 days delinquent or foreclosure proceedings are commenced, at which point interest accrual is discontinued. Interest accrual is not resumed until the loan is brought current. There were no mortgage loans in the Company's portfolio in process of foreclosure or in arrears with respect to principal and interest as of June 30, 2015 and December 31, 2014 . The following tables present information on the average investment during the period in impaired loans and interest income recognized on impaired and troubled debt restructured loans for the periods indicated: Three Months Ended June 30, 2015 2014 Impaired loans, average investment during the period (amortized cost) (1) $ 44.5 $ 88.8 Interest income recognized on impaired loans, on an accrual basis (1) 0.7 1.2 Interest income recognized on impaired loans, on a cash basis (1) 0.7 1.2 Interest income recognized on troubled debt restructured loans, on an accrual basis 0.5 1.0 Six Months Ended June 30, 2015 2014 Impaired loans, average investment during the period (amortized cost) (1) $ 57.6 $ 88.9 Interest income recognized on impaired loans, on an accrual basis (1) 1.6 2.5 Interest income recognized on impaired loans, on a cash basis (1) 1.7 2.2 Interest income recognized on troubled debt restructured loans, on an accrual basis 1.3 2.2 (1) Includes amounts for Troubled debt restructured loans. 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.
