FAIR VALUE MEASUREMENTS
NOTE 5.
FAIR VALUE MEASUREMENTS

Certain assets and liabilities that are measured at fair value on a recurring basis as of March 31, 2013 are measured in accordance with FASB ASC Topic 820-10-05, Fair Value Measurements.  FASB ASC Topic 820-10-05 defines fair value, establishes a framework for measuring fair value and expands the disclosure requirements regarding fair value measurements for financial assets and liabilities as well as for non-financial assets and liabilities that are recognized or disclosed at fair value on a recurring basis in the financial statements.
 
The statement requires fair value measurement be classified and disclosed in one of the following three categories:
 
Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;
 
Level 2: Quoted prices in markets that are not active, or inputs which are observable, either directly or indirectly, for substantially the full term of the asset or liability; and
 
Level 3: Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity).

 The following table summarizes our financial instruments measured at fair value as of March 31, 2013 (in thousands):
