Fair Value Measurements
GAAP utilizes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. The fair value hierarchy gives the highest priority to observable quoted prices (unadjusted) in active markets for identical assets and liabilities and the lowest priority to unobservable inputs.
As of October 29, 2011 and January 29, 2011 the Company had $4,961,000 in Level 2 investments in the form of bank Certificates of Deposit which are used as cash collateral for the issuance of commercial letters of credit. The Company has no Level 3 investments that use significant unobservable inputs.
