Fair Value Measurements [Abstract]

Fair Value Measurements

5. Fair Value Measurements

We account for certain assets and liabilities at fair value. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The hierarchy below lists three levels of fair value based on the extent to which inputs used in measuring fair value are observable in the market. These levels are:

• Level 1 — Observable inputs — quoted prices in active markets for identical assets and liabilities;

• Level 2 — Observable inputs other than the quoted prices in active markets for identical assets and liabilities — includes quoted prices for similar instruments, quoted prices for identical or similar instruments in inactive markets, and amounts derived from valuation models where all significant inputs are observable in active markets; and

• Level 3 — Unobservable inputs — includes amounts derived from valuation models where one or more significant inputs are unobservable and require us to develop relevant assumptions.

At July 31, 2011 and January 31, 2011, we had approximately $1.5 million and $1.4 million, respectively, in assets which are carried at fair value on a recurring basis. These assets, which are reflected in Other Assets in the consolidated balance sheets, consist of available-for-sale investments related to our non-qualified supplemental executive retirement plan (“SERP”). The fair value of these investments was determined using Level 1 inputs.

Our long-term debt approximates fair value as of both July 31, 2011 and January 31, 2011, due to the instrument bearing interest at variable rates that are comparable to what is currently available to us. We entered into the First Amendment with Bank of America on July 21, 2011, at which time our current interest rates were determined. See Note 3 on Debt for a more detailed discussion of the Amended Agreement.
