Fair Value Disclosures [Abstract] |
Fair Value Measurement of Assets and Liabilities | Fair Value Measurement of Assets and Liabilities Fair value is defined as 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 (exit price). A fair value measurement reflects the assumptions market participants would use in pricing an asset or liability based on the best available information. These assumptions include the risk inherent in a particular valuation technique (such as a pricing model) and the risks inherent in the inputs to the model. We classify our inputs to measure fair value using a three-level hierarchy that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. The categorization of financial instruments within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The hierarchy is prioritized into three levels (with Level 3 being the lowest) defined as follows: Level 1: Pricing inputs are based on quoted market prices for identical assets or liabilities in active markets (e.g., NYSE). 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: Pricing inputs include benchmark yields, trade data, reported trades and broker dealer quotes, two-sided markets and industry and economic events, yield to maturity, Municipal Securities Rule Making Board reported trades and vendor trading platform data. Level 2 includes those financial instruments that are valued using various pricing services and broker pricing information including Electronic Communication Networks and broker feeds. Level 3: Pricing inputs include significant inputs that are generally less observable from objective sources, including the Company’s own assumptions. At December 31, 2014, the Company did not have any securities in the Level 3 category. The Company reviews the fair value hierarchy classification on a quarterly basis. We validate the quoted market prices provided by our primary pricing service by comparing their assessment of the fair values of our investments by using a third party investment manager. The third party investment manager uses similar techniques to our primary pricing service to derive the pricing describe above. Changes in the observability of valuation inputs may result in a reclassification of levels for certain securities within the fair value hierarchy. The following table summarizes the Company’s financial instruments measured at fair value on a recurring basis in accordance with the authoritative guidance for fair value measurements as of December 31, 2014 (in thousands):
