FAIR VALUE MEASUREMENTS [Abstract]

FAIR VALUE MEASUREMENTS

NOTE 4.  FAIR VALUE MEASUREMENTS

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability ("exit price") in an orderly transaction between market participants at the measurement date.  When determining fair value, we consider the principal or most advantageous market in which we would transact and consider assumptions that market participants would use when pricing the asset or liability.  The fair value hierarchy distinguishes between (1) market participant assumptions developed based on market data obtained from independent sources (observable inputs) and (2) an entity's own assumptions about market participant assumptions developed based on the best information available in the circumstances (unobservable inputs).  The fair value hierarchy consists of three broad levels, which gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3).  The three levels of the fair value hierarchy are described below:

Level 1:  Quoted prices (unadjusted) in active markets for identical assets or liabilities.

Level 2:  Directly or indirectly observable inputs as of the reporting date through correlation with market data, including quoted prices for similar assets and liabilities in active markets and quoted prices in markets that are not active.  Level 2 also includes assets and liabilities that are valued using models or other pricing methodologies that do not require significant judgment since the input assumptions used in the models, such as interest rates and volatility factors, are corroborated by readily observable data from actively quoted markets for substantially the full term of the financial instrument.

Level 3:  Unobservable inputs that are supported by little or no market data and require the use of significant management judgment.  These values are generally determined using pricing models for which the assumptions utilize management's estimates of market participant assumptions.

The following table summarizes financial assets, measured at fair value on a recurring basis, by level within the fair value hierarchy as of December 31, 2012 and March 31, 2012 (in thousands):

As of December 31, 2012 and March 31, 2012, our Level 1 financial assets are comprised of money market mutual funds.  Our cash equivalents are highly liquid instruments with original or remaining maturities of three months or less at the time of purchase that are readily convertible into cash.  The fair value of our Level 1 financial assets is based on quoted market prices of the underlying security.  As of December 31, 2012 and March 31, 2012, we did not have any Level 1 financial liabilities.

As of December 31, 2012 and March 31, 2012, our Level 2 financial assets are comprised of certificates of deposits, corporate bonds and municipal bonds.  We review trading activity and pricing for these investments as of the measurement date.  When sufficient quoted pricing for identical securities is not available, we use market pricing and other observable market inputs for similar securities obtained from third party data providers.  These inputs represent quoted prices for similar assets in active markets or these inputs have been derived from observable market data.  This approach results in the classification of these securities as Level 2 of the fair value hierarchy.  As of December 31, 2012 and March 31, 2012, we did not have any Level 2 financial liabilities.

As of December 31, 2012 and March 31, 2012, we did not have any Level 3 financial assets or liabilities measured at fair value on a recurring basis.  During the three and nine months ended December 31, 2012 and 2011, we did not have any Level 3 financial assets or liabilities measured at fair value on a recurring basis.
