Investments, Debt and Equity Securities [Abstract] |
Investments | The Company’s investment portfolio includes free-standing derivative financial instruments (currently over the counter (“OTC”) index call option contracts) to economically hedge risk associated with its fixed indexed annuity (“FIA”) and indexed universal life (“IUL”) products’ contingent liabilities. The Company’s FIA and IUL products include embedded derivative features that are discussed in “Note 1 -- Summary of Significant Accounting Policies -- Investment Contract and Life Policy Reserves -- Reserves for Fixed Indexed Annuities and Indexed Universal Life Policies” of the Company’s Annual Report on Form 10-K for the year ended December 31, 2016. The Company’s investment portfolio included no other free-standing derivative financial instruments (futures, forwards, swaps, option contracts or other financial instruments with similar characteristics), and there were no other embedded derivative features related to the Company’s investment or insurance products during the six months ended June 30, 2017 and 2016. Fixed Maturity and Equity Securities The Company’s investment portfolio is comprised primarily of fixed maturity securities and also includes equity securities. The amortized cost or cost, unrealized investment gains and losses, fair values and other-than-temporary impairment (“OTTI”) included in accumulated other comprehensive income (“AOCI”) of all fixed maturity and equity securities in the portfolio were as follows:

(1) | Related to securities for which an unrealized loss was bifurcated to distinguish the credit-related portion and the portion driven by other market factors. Represents the amount of OTTI losses in AOCI which was not included in earnings; amounts also include net unrealized investment gains and losses on such impaired securities relating to changes in the fair value of those securities subsequent to the impairment measurement date.
(2) | Fair value includes securities issued by Federal National Mortgage Association (“FNMA”) of $310,403 thousand and $272,668 thousand; Federal Home Loan Mortgage Corporation (“FHLMC”) of $368,396 thousand and $378,683 thousand; and Government National Mortgage Association (“GNMA”) of $111,458 thousand and $115,627 thousand as of June 30, 2017 and December 31, 2016, respectively.
(3) | Includes nonredeemable (perpetual) preferred stocks, common stocks and closed-end funds.
The following table presents the fair value and gross unrealized losses of fixed maturity and equity securities in an unrealized loss position at June 30, 2017 and December 31, 2016, respectively. The Company views the decrease in value of all of the securities with unrealized losses at June 30, 2017 -- which was driven largely by changes in interest rates, spread widening, financial market illiquidity and/or market volatility from the date of acquisition -- as temporary. For fixed maturity securities, management does not have the intent to sell the securities and it is not more likely than not the Company will be required to sell the securities before the anticipated recovery of the amortized cost bases, and management expects to recover the entire amortized cost bases of the fixed maturity securities. For equity securities, the Company has the ability and intent to hold the securities for the recovery of cost and recovery of cost is expected within a reasonable period of time.

Fixed maturity and equity securities with an investment grade rating represented 82% of the gross unrealized losses as of June 30, 2017. With respect to fixed maturity securities involving securitized financial assets, the underlying collateral cash flows were stress tested to determine there was no adverse change in the present value of cash flows below the amortized cost basis. Credit Losses The following table summarizes the cumulative amounts related to the Company’s credit loss component of OTTI losses on fixed maturity securities held as of June 30, 2017 and 2016 that the Company did not intend to sell as of those dates, and it was not more likely than not that the Company would be required to sell the securities before the anticipated recovery of the amortized cost bases, for which the non-credit portions of OTTI losses were recognized in other comprehensive income:

Maturities/Sales of Fixed Maturity and Equity Securities The following table presents the distribution of the Company’s fixed maturity securities portfolio by estimated expected maturity. Estimated expected maturities differ from contractual maturities, reflecting assumptions regarding borrowers’ utilization of the right to call or prepay obligations with or without call or prepayment penalties. For structured securities, including mortgage-backed securities and other asset-backed securities, estimated expected maturities consider broker-dealer survey prepayment assumptions and are verified for consistency with the interest rate and economic environments.
