Fair Value Disclosures [Abstract] |
Fair Value Measurements | 3. Fair Value Measurements The Company follows authoritative accounting guidance, which among other things, defines fair value, establishes a consistent framework for measuring fair value, and expands disclosure for each major asset and liability category measured at fair value on either a recurring or nonrecurring basis. Fair value is defined as the exchange price that would be received to sell an asset or paid to transfer a liability (at exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The three levels of inputs that may be used to measure fair value include: Level 1: Quoted prices in active markets for identical assets or liabilities. The Company’s Level 1 assets consist of money market funds. Level 2: Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities in active markets or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3: Unobservable inputs that are supported by little or no market activity. The following table identifies the Company’s assets and liabilities that were measured at fair value on a recurring basis (in thousands):
