Fair Value Disclosures [Abstract] |
Fair Value Measurements | 13. Fair Value Measurements U.S. GAAP defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants as of the measurement date. U.S. GAAP describes three approaches to measuring the fair value of assets and liabilities: the market approach, the income approach and the cost approach. Each approach includes multiple valuation techniques. U.S. GAAP does not prescribe which valuation technique should be used when measuring fair value, but does establish a fair value hierarchy that prioritizes the inputs used in applying the various techniques. Inputs broadly refer to the assumptions that market participants use to make pricing decisions, including assumptions about risk. Level 1 inputs are given the highest priority in the hierarchy while Level 3 inputs are given the lowest priority. Assets and liabilities carried at fair value are classified in one of the following three categories based on the nature of the inputs to the valuation technique used:
• | Level 1 — Observable inputs that reflect unadjusted quoted prices for identical assets or liabilities in active markets as of the reporting date. Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis.
• | Level 2 — Observable market-based inputs or unobservable inputs that are corroborated by market data.
• | Level 3 — Unobservable inputs that are not corroborated by market data. These inputs reflect management’s best estimate of fair value using its own assumptions about the assumptions a market participant would use in pricing the asset or liability.
Summary of significant valuation techniques for assets measured at fair value on a recurring basis Level 1 Common stock: Comprise actively traded, exchange-listed U.S. and international equity securities. Valuation is based on unadjusted quoted prices for identical assets in active markets that the Company can access. Mutual funds: Comprise actively traded funds. Valuation is based on daily quoted net asset values for identical assets in active markets that the Company can access. Level 2 U.S. government obligations and agencies: Comprise U.S. Treasury Bills or Notes or U.S. Treasury Inflation Protected Securities. The primary inputs to the valuation include quoted prices for identical assets in inactive markets or similar assets in active or inactive markets, contractual cash flows, benchmark yields and credit spreads. Corporate bonds: Comprise investment-grade fixed income securities. The primary inputs to the valuation include quoted prices for identical assets in inactive markets or similar assets in active or inactive markets, contractual cash flows, benchmark yields and credit spreads. Mortgage-backed and asset-backed securities: Comprise securities that are collateralized by mortgage obligations and other assets. The primary inputs to the valuation include quoted prices for identical assets in inactive markets or similar assets in active or inactive markets, contractual cash flows, benchmark yields, collateral performance and credit spreads. Municipal bonds: Comprise fixed income securities issued by a state, municipality or county. The primary inputs to the valuation include quoted prices for identical assets in inactive markets or similar assets in active or inactive markets, contractual cash flows, benchmark yields and credit spreads. Redeemable preferred stock: Comprise preferred stock securities that are redeemable. The primary inputs to the valuation include quoted prices for identical or similar assets in markets that are not active. Short-term investments: Comprise investment securities subject to re-measurement with original maturities within one year but more than three months. The primary inputs to the valuation include quoted prices for identical or similar assets in markets that are not active. As required by U.S. GAAP, assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement requires judgment, and may affect the placement of the asset or liability within the fair value hierarchy levels. The following tables set forth by level within the fair value hierarchy the Company’s assets that were measured at fair value on a recurring basis as of the dates presented (in thousands):

The Company utilizes third-party independent pricing services that provide a price quote for each available-for-sale debt security, equity security and available-for-sale short-term investment. Management reviews the methodology used by the pricing services. If management believes that the price used by the pricing service does not reflect an orderly transaction between participants, management will use an alternative valuation methodology. There were no adjustments made by the Company to the prices obtained from the independent pricing source for any available-for-sale debt securities, equity securities or available-for-sale short-term investments included in the tables above. The following table summarizes the carrying value and estimated fair values of the Company’s financial instruments that are not carried at fair value as of the dates presented (in thousands):

Surplus note | $ | 12,500 |  |  | $ | 11,271 |  |  | $ | 12,868 |  |  | $ | 11,630 |
Level 3 Long-term debt: The fair value of the surplus note was determined by management from the expected cash flows discounted using the interest rate quoted by the holder. The State Board of Administration of Florida (“SBA”) is the holder of the surplus note and the quoted interest rate is below prevailing rates quoted by private lending institutions. However, as the Company’s use of funds from the surplus note is limited by the terms of the agreement, the Company has determined the interest rate quoted by the SBA to be appropriate for purposes of establishing the fair value of the note.
