Note 2. Fair Value Measurement

The Company considers fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date. Valuation techniques used to measure fair value are either observable or unobservable. Observable inputs reflect assumptions that market participants would use in pricing an asset or liability based on market data obtained from independent sources, while unobservable inputs reflect a reporting entity’s pricing based on their own market assumptions. The Company utilizes the following three-level fair value hierarchy to establish the priorities of the inputs used to measure fair value:

Level 1—instrument valuations are obtained from real-time quotes for transactions in active exchange markets involving identical assets.

Level 2—instrument valuations are obtained from sources other than quoted market prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data.

Level 3—instrument valuations are obtained without observable market values and require a high level of judgment to determine the fair value.

As of September 30, 2011, our warrant liability was $0. The warrant liability decreased by $2,000 and $30,000 during the three and nine months ended September 30, 2011 respectively, and these amounts were recognized as other income. The fair value was calculated using the Black-Scholes option pricing model.
