When inputs used to measure fair value fall within different levels of the hierarchy, the level within which the fair value measurement is categorized is based on the lowest level input that is significant to the fair value measurement. The Company classifies and discloses assets and liabilities carried at fair value in one of the following three categories: Level 1: Inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date; Level 2: Inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly; or Level 3: Inputs are unobservable inputs for the asset or liability. Unobservable inputs are used to measure fair value to the extent that observable inputs are not available, thereby allowing for situations in which there is little, if any, market activity for the asset or liability at the measurement date.

Fair Value of Financial Instruments

Financial assets and liabilities are categorized, based on the inputs to the valuation technique, into a three-level fair value hierarchy. The fair value hierarchy gives the highest priority to the quoted prices in active markets for identical assets and liabilities and the lowest priority to unobservable inputs. Observable market data, when available, is required to be used in making fair value measurements.
