Fair Value Measurements Fair Value Measurements
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.  A three level fair value hierarchy is used to prioritize the inputs used in valuations, as defined below:
Level 1: Observable inputs that reflect unadjusted quoted prices for identical assets or liabilities in active markets.
Level 2:
Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly.
Level 3:
 Unobservable inputs for the asset or liability.
