Fair Value Disclosures [Abstract] |
Fair Value Measurements | Note 11 - Fair Value Measurements The Company classifies its investments in Fixed Maturities and Equity Securities as available for sale and reports these investments at fair value. The Company has elected the fair value option method of accounting for investments in certain hedge funds and, accordingly, reports these investments at fair value. The Company classifies certain investments in mutual funds included in Other Investments as trading securities and reports these investments at fair value. The Company has a derivative instrument that is classified as a cash flow hedge and reported at fair value in Accrued Expenses and Other Liabilities at June 30, 2017. Note 11 - Fair Value Measurements (continued) 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 Sheet. The valuation of assets and liabilities measured at fair value in the Company’s Condensed Consolidated Balance Sheet at June 30, 2017 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 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 Note 11 - Fair Value Measurements (continued) agencies. The Company’s investments in Equity Securities 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 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 Company’s Investments in Fixed Maturities that are classified as Level 3 in the two preceding tables primarily consist of privately placed securities not rated by a Nationally Recognized Statistical Rating Organization and are priced primarily using a market yield approach. A market yield approach uses a risk-free rate plus a credit spread depending on the underlying credit profile of the security. For floating rate securities, the risk-free rate used in the market yield is the contractual floating rate of the security. For each individual security, the Company or the Company’s third party appraiser gathers information from market sources, relevant credit information, perceived market movements and sector news and determines an appropriate market yield for each security. The market yield selected is then used to discount the estimated future cash flows of the security to determine the fair value. The Company separately evaluates market yields based upon asset class to assess the reasonableness of the recorded fair value. For non-investment-grade Investments in Fixed Maturities that are classified as Level 3, the two primary asset classes are senior debt and junior debt. Senior debt includes those securities that receive first priority in a liquidation and junior debt includes any fixed maturity security with other than first priority in a liquidation. The table below presents quantitative information about the significant unobservable inputs utilized by the Company in determining fair values for fixed maturity investments in corporate securities classified as Level 3 at June 30, 2017.

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. The Company’s other investments that are classified as Level 3 primarily consist of Limited Liability Companies and Limited Partnerships, but also certain Preferred Stocks and Common Stocks. The Company either uses valuations provided by third party fund managers or third party appraisers, or that are generated internally. These valuations typically employ various valuation techniques commonly used in the industry, including earnings multiples based on comparable public securities, industry-specific non-earnings based multiples, market yields based on comparable public securities and discounted cash flow models. Information by security type pertaining to the changes in the fair value of the Company’s investments classified as Level 3 for the six months ended June 30, 2017 is presented below.

The Company’s policy is to recognize transfers between levels as of the end of the reporting period. There were no transfers between levels 1 and 2 for the six and three months ended June 30, 2017. Transfers out of Level 3 were $24.8 million for the six months ended June 30, 2017, of which $3.5 million was transferred into Level 1 due to an issuer’s initial public offering of the security and $21.3 million was transferred into Level 2 due to changes in the availability of market observable inputs. Transfers out of Level 3 were $14.0 million for the three months ended June 30, 2017, of which $3.5 million was transferred into Level 1 due to an issuer’s initial public offering of the security and $10.5 million was transferred into Level 2 due to changes in the availability of market observable inputs.

There were no transfers between levels for the six and three months ended June 30, 2016. The fair value of Debt is estimated using quoted prices for similar liabilities in markets that are not active. The inputs used in the valuation are considered Level 2 measurements. The fair value of Short-term Investments is estimated using inputs that are considered either Level 1 or Level 2 measurements.
