Fair Value Disclosures [Abstract] |
Fair Value Measurements | Fair Value Measurements The Company classifies its investments in Fixed Maturities as available-for-sale and reports these investments at fair value. The Company reports equity investments with readily determinable fair values as Equity Securities at Fair Value. Certain investments that are measured at fair value using the net asset value practical expedient are not required to be classified using the fair value hierarchy, but are presented in the following two tables to permit reconciliation of the fair value hierarchy to the amounts presented in the Condensed Consolidated Balance Sheets. The valuation of assets measured at fair value in Company’s Condensed Consolidated Balance Sheets at March 31, 2021 is summarized below.

The Company’s investments in Fixed Maturities that are classified as Level 1 in the two preceding tables primarily consist of U.S. Treasury Bonds and Notes. The Company’s investments in Equity Securities at Fair Value that are classified as Level 1 in the two preceding tables consist of either investments in publicly-traded common stocks or exchange traded funds. The Company’s investments in Fixed Maturities that are classified as Level 2 in the two preceding tables primarily consist of investments in corporate bonds, obligations of states and political subdivisions, and bonds and mortgage-backed securities of U.S. government agencies. The Company’s investments in Equity Securities at Fair Value that are classified as Level 2 in the two preceding tables primarily consist of investments in preferred stocks. The Company uses a leading, nationally recognized provider of market data and analytics to price the vast majority of the Company’s Level 2 measurements. The provider utilizes evaluated pricing models that vary by asset class and incorporate available trade, bid and other market information. Because many fixed maturity securities do not trade on a daily basis, the provider’s evaluated pricing applications apply available Note 6 - Fair Value Measurements (continued) information through processes such as benchmark curves, benchmarking of like securities, sector groupings and matrix pricing to prepare evaluations. In addition, the provider uses model processes to develop prepayment and interest rate scenarios. The pricing provider’s models and processes also take into account market convention. For each asset class, teams of its evaluators gather information from market sources and integrate relevant credit information, perceived market movements and sector news into the evaluated pricing applications and models. The Company generally validates the measurements obtained from its primary pricing provider by comparing them with measurements obtained from one additional pricing provider that provides either prices from recent market transactions, quotes in inactive markets or evaluations based on its own proprietary models. The Company investigates significant differences related to the values provided. On completion of its investigation, management exercises judgment to determine the price selected and whether adjustments, if any, to the price obtained from the Company’s primary pricing provider would warrant classification of the price as Level 3. In instances where a measurement cannot be obtained from either pricing provider, the Company generally will evaluate bid prices from one or more binding quotes obtained from market makers to value investments in inactive markets and classified by the Company as Level 2. The Company generally classifies securities when it receives non-binding quotes or indications as Level 3 securities unless the Company can validate the quote or indication against recent transactions in the market. The table below presents quantitative information about the significant unobservable inputs utilized by the Company in determining fair values for fixed maturity investments classified as Level 3 at March 31, 2021.

Note 6 - Fair Value Measurements (continued) For an investment in a fixed maturity security, an increase in the yield used to determine the fair value of the security will decrease the fair value of the security. A decrease in the yield used to determine fair value will increase the fair value of the security, but the fair value increase is generally limited to par, unless callable at a premium, if the security is currently callable. Information by security type pertaining to the changes in the fair value of the Company’s investments classified as Level 3 for the three months ended March 31, 2021 is presented below.
