FAIR VALUE MEASUREMENTS
 
2. FAIR VALUE MEASUREMENTS

When determining fair value the Company uses a three-tier value hierarchy, which prioritizes the inputs used in measuring fair value.  Whenever possible, the Company uses observable market data and relies on unobservable inputs only when observable market data is not available.  Classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement.

The following table sets forth the Company's financial assets, measured at fair value, as of January 31, 2012 and 2011:

Money market mutual funds are classified as part of “Cash and equivalents” in the accompanying Consolidated Balance Sheets and are classified within Level 1 of the fair value hierarchy because they are valued using quoted market prices. As of January 31, 2012 and 2011, the amount of cash and cash equivalents included cash deposited with commercial banks of $28.7 million and $18.9 million, respectively.

There have been no transfers between fair value measurement levels during the year ended January 31, 2012.
