FAIR VALUE MEASUREMENTS

FAIR VALUE MEASUREMENTS

6. FAIR VALUE MEASUREMENTS

The Company has categorized its financial assets, based on the priority of the inputs to the valuation technique, into a three-level fair value hierarchy as set forth below. If the inputs used to measure a financial instrument fall within different levels of the hierarchy, the categorization of such financial asset is based on the lowest level input that is significant to the fair value measurement of such instrument.

Financial assets are categorized based on the inputs to the valuation techniques as follows:

Level 1 - Financial assets whose values are based on unadjusted quoted prices for identical assets or liabilities in an active market that the Company has the ability to access at the measurement date (examples include actively exchange-traded equity securities, listed derivatives, and most U.S. government and agency securities).

Level 2 - Financial assets whose values are based on quoted prices in markets where trading occurs infrequently or whose values are based on quoted prices of instruments with similar attributes in active markets.  Level 2 inputs include the following:

· Quoted prices for identical or similar assets or liabilities in non-active markets;

· Inputs other than quoted prices that are observable for substantially the full term of the asset or liability; and

· Inputs that are derived principally from or corroborated by observable market data for substantially the full term of the asset or liability.

Level 3 - Financial assets whose values are based on prices or valuation techniques that require inputs that are both unobservable and significant to the overall fair value measurement. These inputs reflect management’s assumptions about the assumptions a market participant would use in pricing the asset or liability. The Company currently does not have any Level 3 financial assets or liabilities.

The following table presents the financial assets that the Company measures at fair value on a recurring basis, based on the fair value hierarchy as of September 30, 2013 and March 31, 2013:

The Company had no material realized gains or losses on its available-for-sale securities for the three or six months ended September 30, 2013 and September 30, 2012, respectively.
