Fair Value Disclosures [Abstract]  
Fair Value Measurements Fair Value Measurements
Fair value is defined as the exchange price that would be received for an asset or an exit price paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs.
The three-levels of the valuation hierarchy for disclosure of fair value measurements are defined as follows:
Level 1 -    Unadjusted quoted prices in active markets for identical assets or liabilities;
Level 2 -    Inputs other than quoted prices included within Level I that are observable, unadjusted quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the related assets or liabilities; and
Level 3 -    Unobservable inputs that are supported by little or no market activity for the related assets or liabilities.
The categorization of a financial instrument within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The following table sets forth the Company's financial instruments that were measured at fair value on a recurring basis within the fair value hierarchy (in thousands):
