The Company uses fair value measurements to record fair value adjustments to certain assets to determine fair value disclosures. Fixed maturity available-for-sale securities and equity securities are recorded at fair value on a recurring basis. FASB ASC Topic 820 “Fair Value Measurements and Disclosures” establishes a fair value hierarchy that prioritizes the inputs to valuation methods used to measure fair value. The three levels of the fair value hierarchy under ASC Topic 820 are as follows:

Under ASC Topic 820, we base fair values of assets on the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. It is our policy to maximize the use of observable inputs and minimize the use of unobservable inputs when developing fair value measurements, in accordance with the fair value hierarchy in FASB ASC Topic 820. Fair value measurements for assets where there exists limited or no observable market data and, therefore, are based primarily upon our or other third-party’s estimates, are often calculated based on the characteristics of the asset, the economic and competitive environment and other such factors. Management uses its best judgment in estimating the fair value of financial instruments; however, there are inherent weaknesses in any estimation technique. Therefore, for substantially all financial instruments, the fair value estimates herein are not necessarily indicative of the amounts we could have realized in a sales transaction on the dates indicated. The estimated fair value amounts have been measured as of their respective period end and have not been re-evaluated or updated for purposes of the consolidated financial statements subsequent to those respective dates. As such, the estimated fair values of these financial instruments subsequent to the respective reporting dates may be different than the amounts reported at each period-end. Additionally, changes in the underlying assumptions used, including discount rates and estimates of future cash flows, could significantly affect the results of current or future valuations.

We obtain one price for each security primarily from a third-party pricing service (“pricing service”), which generally uses quoted prices or other observable inputs for the determination of fair value. The pricing service normally derives the security prices through recently reported trades for identical or similar securities, making adjustments through the reporting date based upon available observable market information. For securities not actively traded, the pricing service may use quoted market prices of comparable instruments or discounted cash flow analyses, incorporating inputs that are currently observable in the markets for similar securities. Inputs that are often used in the valuation methodologies include, but are not limited to, non-binding broker quotes, benchmark yields, credit spreads, default rates, and prepayment speeds.

In instances in which the inputs used to measure fair value fall into different levels of the fair value hierarchy, the fair value measurement has been determined based on the lowest-level input that is significant to the fair value measurement in its entirety. Our assessment of the significance of a particular item to the fair value measurement in its entirety requires judgment, including the consideration of inputs specific to the asset or liability.

Fair values of interest rate sensitive instruments may be affected by increases and decreases in prevailing interest rates, which generally translate, respectively, into decreases and increases in fair values of fixed maturity investments. The fair values of interest rate sensitive instruments also may be affected by the credit worthiness of the issuer, prepayment options, relative values of other investments, the liquidity of the instrument, and other general market conditions.

We evaluated each security and took into account the severity and duration of the impairment, the current rating on the bond, and the outlook for the issuer according to independent analysts. We found that the declines in fair value are most likely attributable to increases in interest rates, and there is no evidence that the likelihood of not receiving all of the contractual cash flows as expected has changed. Our fixed maturity portfolio is managed by our investment committee in concert with an outside investment manager for investment grade bond investments. By agreement, the investment manager cannot sell any security without the consent of our investment committee if such sale will result in a net realized loss.

We monitor our investment portfolio and review securities that have experienced a decline in fair value below cost to evaluate whether the decline is other than temporary. When assessing whether the amortized cost basis of the security will be recovered, we compare the present value of the cash flows likely to be collected, based on an evaluation of all available information relevant to the collectability of the security, to the amortized cost basis of the security. The shortfall of the present value of the cash flows expected to be collected in relation to the amortized cost basis is referred to as the “credit loss.” If there is a credit loss, the impairment is considered to be other-than-temporary. If we identify that an other-than-temporary impairment loss has occurred, we then determine whether we intend to sell the security, or if it is more likely than not that we will be required to sell the security prior to recovering the amortized cost basis less any current-period credit losses. If we determine that we do not intend to sell, and it is more likely than not that we won’t be required to sell the security, then the amount of the impairment loss related to the credit loss will be recorded in earnings, and the remaining portion of the other-than-temporary impairment loss will be recognized in other comprehensive income (loss), net of tax. If we determine that we intend to sell the security, or that it is more likely than not that we will be required to sell the security prior to recovering its amortized cost basis less any current-period credit losses, then the full amount of the other-than-temporary impairment will be recognized in earnings.

For the three months ended March 31, 2020 and 2019, we determined that none of our fixed maturity securities were other-than-temporarily impaired. Adverse investment market conditions, or poor operating results of underlying investments, could result in impairment charges in the future.
