Excluding investments in U.S. government and government agencies, the Company is not exposed to any significant concentration of credit risk in its fixed maturity securities portfolio. The amortized cost and estimated fair value of fixed maturity AFS securities by investment grade at June 30, 2017 and December 31, 2016 were: June 30, 2017 December 31, 2016 Estimated Estimated Amortized Fair Amortized Fair Cost Value Cost Value Investment grade $ 1,268,702 $ 1,386,926 $ 1,294,978 $ 1,393,503 Below investment grade 79,216 87,900 88,809 93,534 Total fixed maturity AFS securities $ 1,347,918 $ 1,474,826 $ 1,383,787 $ 1,487,037 At June 30, 2017 and December 31, 2016, the estimated fair value of fixed maturity securities rated BBB-, which is the lowest investment grade rating given by rating agencies, was $58,930 and $65,730, respectively. Below investment grade securities are speculative and are subject to significantly greater risks related to the creditworthiness of the issuers and the liquidity of the market for such securities. The Company closely monitors such investments to assess whether they are other-than-temporarily impaired. The amortized cost and estimated fair value of fixed maturity AFS securities at June 30, 2017 and December 31, 2016 by contractual maturities were: June 30, 2017 December 31, 2016 Estimated Estimated Amortized Fair Amortized Fair Cost Value Cost Value Fixed maturity AFS securities Due in one year or less $ 78,733 $ 80,116 $ 56,748 $ 57,489 Due after one year through five years 450,657 477,698 523,815 555,221 Due after five years through ten years 118,259 124,484 95,744 99,697 Due after ten years 497,496 582,290 485,720 549,354 $ 1,145,145 $ 1,264,588 $ 1,162,027 $ 1,261,761 Mortgage-backed securities and other asset-backed securities $ 202,773 $ 210,238 $ 221,760 $ 225,276 Total fixed maturity AFS securities $ 1,347,918 $ 1,474,826 $ 1,383,787 $ 1,487,037 In the preceding table, fixed maturity securities not due at a single maturity date have been included in the year of final maturity. Actual maturities may differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties. Unrealized Losses on Fixed Maturity and Equity Securities The Company’s investments in fixed maturity and equity securities classified as AFS are carried at estimated fair value with unrealized gains and losses included in stockholder’s equity as a component of AOCI, net of taxes. The estimated fair value and gross unrealized losses and OTTI related to fixed maturity and equity AFS securities aggregated by length of time that individual securities have been in a continuous unrealized loss position at June 30, 2017 and December 31, 2016 were as follows: June 30, 2017 Gross Estimated Unrealized Fair Amortized Losses and Value Cost/Cost OTTI (a) Less than or equal to six months Fixed maturity AFS securities Corporate securities $ 3,212 $ 3,288 $ (76 ) Asset-backed securities 21,820 21,842 (22 ) Commercial mortgage-backed securities 10,578 10,678 (100 ) Residential mortgage-backed securities 2,880 2,924 (44 ) Government and government agencies United States 6,593 6,623 (30 ) Foreign 3,789 3,811 (22 ) Equity securities 5,786 5,791 (5 ) Total fixed maturity and equity AFS securities $ 54,658 $ 54,957 $ (299 ) Greater than six months but less than or equal to one year Fixed maturity AFS securities Corporate securities $ 19,522 $ 19,832 $ (310 ) Asset-backed securities 6,948 7,051 (103 ) Commercial mortgage-backed securities 13,169 13,316 (147 ) Total fixed maturity and equity AFS securities $ 39,639 $ 40,199 $ (560 ) Greater than one year Fixed maturity AFS securities Corporate securities $ 9,383 $ 10,489 $ (1,106 ) Asset-backed securities 8,997 9,127 (130 ) Residential mortgage-backed securities 9 9 - Municipals 874 907 (33 ) Total fixed maturity and equity AFS securities $ 19,263 $ 20,532 $ (1,269 ) Total fixed maturity and equity AFS securities $ 113,560 $ 115,688 $ (2,128 ) December 31, 2016 Gross Estimated Unrealized Fair Amortized Losses and Value Cost/Cost OTTI (a) Less than or equal to six months Fixed maturity AFS securities Corporate securities $ 64,992 $ 66,625 $ (1,633 ) Asset-backed securities 30,729 31,253 (524 ) Commercial mortgage-backed securities 30,698 31,285 (587 ) Residential mortgage-backed securities 54,987 55,690 (703 ) Equity securities - banking securities 8,213 8,500 (287 ) Total fixed maturity and equity AFS securities $ 189,619 $ 193,353 $ (3,734 ) Greater than six months but less than or equal to one year Fixed maturity AFS securities Corporate securities $ 4,522 $ 4,863 $ (341 ) Asset-backed securities 879 1,000 (121 ) Commercial mortgage-backed securities 1,010 1,012 (2 ) Residential mortgage-backed securities 212 229 (17 ) Total fixed maturity and equity AFS securities $ 6,623 $ 7,104 $ (481 ) Greater than one year Fixed maturity AFS securities Corporate securities $ 19,541 $ 21,131 $ (1,590 ) Asset-backed securities 7,978 8,182 (204 ) Residential mortgage-backed securities 2,122 2,172 (50 ) Municipals 856 909 (53 ) Equity AFS securities - banking securities 1,615 1,796 (181 ) Total fixed maturity and equity AFS securities $ 32,112 $ 34,190 $ (2,078 ) Total fixed maturity and equity AFS securities $ 228,354 $ 234,647 $ (6,293 ) (a) Subsequent unrealized gains (losses) on OTTI securities are included in Net unrealized OTTI on securities in the Statements of Comprehensive Income (Loss). The total number of securities in an unrealized loss position was 49 and 81 at June 30, 2017 and December 31, 2016, respectively. The Company held 354 and 360 total securities at June 30, 2017 and December 31, 2016, respectively. The fair value, gross unrealized losses/the portion of OTTI recognized in OCI and the number of securities with fair value declining below amortized cost by greater than 20% and 40% by length of time that securities have been in a continuous unrealized loss position were as follows at June 30, 2017 and December 31, 2016: June 30, 2017 December 31, 2016 Estimated Gross Unrealized Number of Estimated Gross Unrealized Number of Fair Value Losses/OTTI (a) Securities Fair Value Losses/OTTI (a) Securities Decline 20% - 40% Held greater than one year $ 1,195 $ (794 ) 1 $ 1,375 $ (614 ) 1 Total $ 1,195 $ (794 ) 1 $ 1,375 $ (614 ) 1 (a) Subsequent unrealized gains (losses) on OTTI securities are included in Net unrealized OTTI on securities in the Statements of Comprehensive Income (Loss). Unrealized gains (losses) incurred during the first six months of 2017 and twelve months of 2016 were primarily due to price fluctuations resulting from changes in interest rates and credit spreads. If the Company has the intent to sell or it is more likely than not that the Company will be required to sell these securities prior to the anticipated recovery of the amortized cost, securities are written down to fair value. If cash flow models indicate a credit event will impact future cash flows, the security is impaired to discounted cash flows. For fixed maturity AFS securities, the Company does not intend to sell them, nor is it more likely than not that the Company will be required to sell them before the recovery of its amortized cost basis, and the Company expects to recover the entire cost basis of the debt securities. In making the other-than-temporary impairment assessment, the Company also considered all available information relevant to the collectability of the security, including information about past events, current conditions, and reasonable and supportable forecasts, when developing the estimate of cash flows expected to be collected. Therefore, the Company determined that these fixed maturity AFS securities were not other-than-temporarily impaired. The components of net unrealized gains (losses) and OTTI included in AOCI, net of taxes, at June 30, 2017 and December 31, 2016 were as follows: June 30, December 31, 2017 2016 Assets Fixed maturity AFS securities $ 126,908 $ 103,250 Equity AFS securities 2,665 1,287 Cash flow hedges 2,088 (1,224 ) Value of business acquired (30,589 ) (26,630 ) $ 101,072 $ 76,683 Liabilities Income taxes - deferred $ (21,333 ) $ (21,333 ) Stockholder's Equity Accumulated other comprehensive income, net of taxes $ 79,739 $ 55,350 Mortgage Loans on Real Estate Mortgage loans on real estate consist entirely of mortgages on commercial real estate. Prepayment premiums are collected when borrowers elect to prepay their debt prior to the stated maturity. There in prepayment premiums collected during the three and six months ended June 30, 2017. The fair values of mortgage loans on real estate are estimated by discounting the future cash flows using the current rates at which similar loans would be made to borrowers with similar credit ratings and/or similar remaining maturities. The estimated fair value of the mortgages on commercial real estate at June 30, 2017 and December 31, 2016 was $126,881 and $115,020, respectively. Loans are considered impaired when it is probable that, based upon current information and events, the Company will be unable to collect all amounts due under the contractual terms of the loan agreement. A valuation allowance is established when a loan is determined to be impaired for the excess carrying value of the loan over its estimated collateral value. There were no impaired mortgage loans at June 30, 2017 and December 31, 2016. For the portion of the mortgage loan portfolio without specific reserves, an allowance for credit losses is established. The change in the allowance for credit losses is reflected in net realized investment gains (losses), excluding OTTI losses on securities, in the Statements of Income (Loss). The commercial mortgages are geographically diversified throughout the United States with the largest concentrations in Texas, Pennsylvania, Wisconsin, Florida, California, Missouri, Washington, Georgia, Virginia, Utah, Minnesota and Tennessee, The credit quality of commercial mortgage loans at June 30, 2017 and December 31, 2016, was as follows: June 30, December 31, Commercial 2017 2016 AAA - AA $ 43,289 $ 43,047 A 58,022 55,269 BBB 22,599 17,970 Total mortgage loans on real estate $ 123,910 $ 116,286 Less: allowance for credit losses (90 ) (78 ) Total mortgage loans on real estate, net $ 123,820 $ 116,208 The credit quality of the commercial mortgage loans was determined based on an internal credit rating model that assigns a letter rating to each mortgage loan in the portfolio as an indicator of the quality of the mortgage loan. The internal credit rating model was designed based on a rating agency methodology, then modified for credit risk associated with the Company’s mortgage lending process, taking into account such factors as projected future cash flows, net operating income, and collateral value. The model produces a rating score and an associated letter rating that is intended to align with S&P Global Rating Services (“S&P GRS”) ratings as closely as possible. Information supporting the risk rating process is updated at least annually. While mortgage loans with a lower rating carry a higher risk of loss, an adequate allowance for credit losses has been established to cover those risks.

At June 30, 2017, the before-tax deferred net gains (losses) on derivatives recorded in AOCI that are expected to be reclassified to the Statements of Income (Loss) during the next twelve months are ($1,241). This expectation is based on the anticipated interest payments on the hedged investments in Treasury Inflation Protection Securities that will occur over the next twelve months, at which time the Company will recognize the deferred gains (losses) as an adjustment to interest income over the term of the investment cash flows. In addition, in order to trade futures, the Company is required to post collateral to an exchange (sometimes referred to as margin). The fair value of collateral posted in relation to the futures margin was $5,630 and $5,276 at June 30, 2017 and December 31, 2016, respectively. Offsetting of Derivative Instruments The Company has derivative instruments that are subject to master netting agreements.

(2) The amount of cash collateral offset in the table above is limited to the net estimated fair value of derivatives after application of netting agreements. Cash collateral received for over-the-counter ("OTC") OTC-Bilateral and OTC-Cleared derivatives is included in cash and cash equivalents, short-term investments, or fixed maturity securities, and the obligation to return it, beyond what is already being setoff, is included in payables for collateral under securities loaned, reverse repurchase agreements and derivatives. At June 30, 2017, the Company received $9 of excess cash collateral. The Company had no excess cash collateral received from counterparties at December 31, 2016 (3) The receivable for the return of cash collateral provided to the counterparty, beyond what is being setoff, is included in other assets. The amount reported in the table above does not include initial margin on exchange-traded and OTC-Cleared derivatives. At June 30, 2017 and December 31, 2016, the Company had no excess cash collateral provided to counterparties that was excluded from the table due to the foregoing limitation. (4) Securities collateral received or pledged by the Company is held in separate custodial accounts and is not recorded on the Balance Sheets. The amount of securities collateral offset in the table above is limited to the net estimated fair value of derivatives after application of netting agreements and cash collateral. At June 30, 2017 and December 31, 2016, the Company received excess securities collateral with an estimated fair value of $5,041 and $395, respectively, for its OTC-Bilateral derivatives, which are not included in the table above due to the foregoing limitation. At June 30, 2017 and December 31, 2016, the Company provided excess securities collateral with an estimated fair value of $1,956 and $1,878, respectively, for its OTC-Bilateral derivatives, which are not included in the table above due to the foregoing limitation. At June 30, 2017 and December 31, 2016, the Company also provided securities initial margin with an estimated fair value of $11,405 and $11,291, respectively, for its OTC-Cleared derivatives, which are not included in the table above.
