Jun. 30, 2017
Fair Value Disclosures [Abstract] |
Fair Value of Financial Instruments | The Company is required under GAAP to disclose estimated fair values for certain financial and nonfinancial assets and liabilities. Fair values of the Company’s insurance contracts other than annuity contracts are not required to be disclosed. However, the estimated fair values of liabilities under all insurance contracts are taken into consideration in the Company’s overall management of interest rate risk through the matching of investment maturities with amounts due under insurance contracts. Information regarding the three-level hierarchy presented below and the valuation methodologies utilized by the Company to estimate fair values at a point in time is included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016, specifically in “Note 3 -- Fair Value of Financial Instruments”. Financial Instruments Measured and Carried at Fair Value The following table presents the Company’s fair value hierarchy for those assets and liabilities measured and carried at fair value on a recurring basis. At June 30, 2017, Level 3 invested assets comprised 3.1% of the Company’s total investment portfolio fair value.

(3) | Transfers into and out of Level 3 during the three and six months ended June 30, 2016 were attributable to changes in the availability of observable market information for individual fixed maturity securities. The Company’s policy is to recognize transfers into and transfers out of the levels as having occurred at the end of the reporting period in which the transfers were determined.
At June 30, 2017, the Company impaired two Level 3 securities for a $1,714 thousand realized loss. At June 30, 2016, there were no net realized investment gains or losses included in earnings that were attributable to changes in the fair value of Level 3 assets still held. For the three and six months ended June 30, 2017, net realized losses of $1,238 thousand and $3,546 thousand, respectively, were included in earnings that were attributable to the changes in the fair value of Level 3 liabilities (embedded derivatives) still held; for the three and six months ended June 30, 2016, the respective amounts were $1,324 thousand and $1,998 thousand. The valuation techniques and significant unobservable inputs used in the fair value measurement for financial assets classified as Level 3 are subject to the control processes as described in “Note 3 -- Fair Value of Financial Instruments -- Investments” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016. Generally, valuation techniques for fixed maturity securities include spread pricing, matrix pricing and discounted cash flow methodologies; include inputs such as quoted prices for identical or similar securities that are less liquid; and are based on lower levels of trading activity than securities classified as Level 2. The valuation techniques and significant unobservable inputs used in the fair value measurement for equity securities classified as Level 3 use similar valuation techniques and significant unobservable inputs as those used for fixed maturity securities. The sensitivity of the estimated fair values to changes in the significant unobservable inputs for fixed maturity and equity securities included in Level 3 generally relates to interest rate spreads, illiquidity premiums and default rates. Significant spread widening in isolation will adversely impact the overall valuation, while significant spread tightening will lead to substantial valuation increases. Significant increases (decreases) in illiquidity premiums in isolation will result in substantially lower (higher) valuations. Significant increases (decreases) in expected default rates in isolation will result in substantially lower (higher) valuations. Financial Instruments Not Carried at Fair Value; Disclosure Required The Company has various other financial assets and financial liabilities used in the normal course of business that are not carried at fair value, but for which fair value disclosure is required. The following table presents the carrying value, fair value and fair value hierarchy of these financial assets and financial liabilities.
