Fair Value Measurements
Note 3.   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.

The fair values of the Company's assets and liabilities measured on a recurring basis are categorized as follows:
