Fair Value Measurement

The Company employs a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The fair value of a financial instrument is the amount 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 using the exit price. Accordingly, when market observable data are not readily available, the Company’s own assumptions are set to reflect those that market participants would be presumed to use in pricing the asset or liability at the measurement date. Assets and liabilities recorded on the consolidated balance sheets at fair value are categorized based on the level of judgment associated with inputs used to measure their fair value and the level of market price observability, as follows:



Level 1	Unadjusted quoted prices are available in active markets for identical assets or liabilities as of the reporting date.



Level 2	Pricing inputs are other than quoted prices in active markets, which are based on the following:


•	Quoted prices for similar assets or liabilities in active markets;


•	Quoted prices for identical or similar assets or liabilities in non-active markets; or


•	Either directly or indirectly observable inputs as of the reporting date.



Level 3	Pricing inputs are unobservable and significant to the overall fair value measurement, and the determination of fair value requires significant management judgment or estimation.

In certain cases, inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, the level in the fair value hierarchy within which the fair value measurement in its entirety falls has been determined based on the lowest level input that is significant to the fair value measurement in its entirety. Thus, a Level 3 fair value measurement may include inputs that are observable (Level 1 or Level 2) and unobservable (Level 3). The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and consideration of factors specific to the asset or liability.

The Company uses prices and inputs that are current as of the measurement date, including during periods of market disruption. In periods of market disruption, the ability to observe prices and inputs may be reduced for many instruments. This condition could cause an instrument to be reclassified from Level 1 to Level 2, or from Level 2 to Level 3. The Company recognizes transfers between levels at either the actual date of the event or a change in circumstances that caused the transfer.

Summary of Significant Valuation Techniques for Financial Assets and Financial Liabilities

The Company’s fair value measurements are based on the market approach, which utilizes market transaction data for the same or similar instruments.

The Company obtained unadjusted fair values on 99.7% of its portfolio from an independent pricing service. For 0.3% of its portfolio, classified as Level 3, the Company obtained specific unadjusted broker quotes based on net fund value and, to a lesser extent, unobservable inputs from at least one knowledgeable outside security broker to determine the fair value as of December 31, 2014.

Level 1 Measurements—Fair values of financial assets and financial liabilities are obtained from an independent pricing service, and are based on unadjusted quoted prices for identical assets or liabilities in active markets. Additional pricing services and closing exchange values are used as a comparison to ensure that reasonable fair values are used in pricing the investment portfolio.

U.S. government bonds and agencies/Short-term bonds: Valued using unadjusted quoted market prices for identical assets in active markets.

Common stock: Comprised of actively traded, exchange listed U.S. and international equity securities and valued based on unadjusted quoted prices for identical assets in active markets.

Money market instruments: Valued based on unadjusted quoted prices for identical assets.

Equity contracts: Comprised of free-standing exchange listed derivatives that are actively traded and valued based on quoted prices for identical instruments in active markets.

Level 2 Measurements—Fair values of financial assets and financial liabilities are obtained from an independent pricing service or outside brokers, and are based on prices for similar assets or liabilities in active markets or valuation models whose inputs are observable, directly or indirectly, for substantially the full term of the asset or liability. Additional pricing services are used as a comparison to ensure reliable fair values are used in pricing the investment portfolio.

Municipal securities: Valued based on models or matrices using inputs such as quoted prices for identical or similar assets in active markets.

Mortgage-backed securities: Comprised of securities that are collateralized by mortgage loans and valued based on models or matrices using multiple observable inputs, such as benchmark yields, reported trades and broker/dealer quotes, for identical or similar assets in active markets. The Company had holdings of $32.5 million and $21.9 million at December 31, 2014 and 2013, respectively, in commercial mortgage-backed securities.

Corporate securities/Short-term bonds: Valued based on a multi-dimensional model using multiple observable inputs, such as benchmark yields, reported trades, broker/dealer quotes and issue spreads, for identical or similar assets in active markets.

Non-redeemable preferred stock: Valued based on observable inputs, such as underlying and common stock of same issuer and appropriate spread over a comparable U.S. Treasury security, for identical or similar assets in active markets.

Total return swap/Interest rate swap: Valued based on models using inputs such as interest rate yield curves, underlying debt/credit instruments and the appropriate benchmark spread for similar assets in active markets, observable for substantially the full term of the contract.

Collateralized loan obligations: Valued based on underlying debt instruments and the appropriate benchmark spread for similar assets in active markets.

Level 3 Measurements—Fair values of financial assets are based on inputs that are both unobservable and significant to the overall fair value measurement, including any items in which the evaluated prices obtained elsewhere were deemed to be of a distressed trading level.

Collateralized debt obligations/Partnership interest in a private credit fund: Valued based on underlying debt/credit instruments and the appropriate benchmark spread for similar assets in active markets; taking into consideration unobservable inputs related to liquidity assumptions.

The Company’s financial instruments at fair value are reflected in the consolidated balance sheets on a trade-date basis. Related unrealized gains or losses are recognized in net realized investment gains (losses) in the consolidated statements of operations. Fair value measurements are not adjusted for transaction costs.
