Fair value is 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. Financial assets and liabilities measured and reported at fair value are classified and disclosed in one of the following categories:

As of April 28, 2012 and January 28, 2012, the Company held certain assets that are required to be measured at fair value on a recurring basis including available-for-sale and trading securities. The Company’s available-for-sale securities include its investments in ARS, as further described in Note 4. The failed auctions, beginning in February 2008, related to certain of the Company’s investments in ARS have limited the availability of quoted market prices. The Company has determined the fair value of its ARS using Level 1 inputs for known or anticipated subsequent redemptions at par value, Level 2 inputs using observable inputs, and Level 3 using unobservable inputs where the following criteria were considered in estimating fair value:

In addition, the Company considers other factors including, but not limited to, the financial condition of the investee, the credit rating, insurance, guarantees, collateral, cash flows, and the current and expected market and industry conditions in which the investee operates. Management believes it has used information that was reasonably obtainable in order to complete its valuation process and determine if the Company’s investments in ARS had incurred any temporary and/or other-than-temporary impairment as of April 28, 2012 and January 28, 2012.

Future fluctuations in fair value of ARS that the Company judges to be temporary, including any recoveries of previous write-downs, would be recorded as an adjustment to “accumulated other comprehensive loss.”  The value and liquidity of ARS held by the Company may be affected by continued auction-rate failures, the credit quality of each security, the amount and timing of interest payments, the amount and timing of future principal payments, and the probability of full repayment of the principal. Additional indicators of impairment include the duration and severity of the decline in market value. The interest rates on these investments will be determined by the terms of each individual ARS. The material risks associated with the ARS held by the Company include those stated above as well as the current economic environment, downgrading of credit ratings on investments held, and the volatility of the entities backing each of the issues.

The Company’s financial assets measured at fair value on a recurring basis were as follows:

Securities included in Level 1 represent securities which have a known or anticipated upcoming redemption as of the reporting date and those that have publicly traded quoted prices. ARS included in Level 2 represent securities which have not experienced a successful auction subsequent to the end of fiscal 2007. The fair market value for these securities was determined by applying a discount to par value based on auction prices for similar securities and by utilizing a discounted cash flow model, using market-based inputs, to determine fair value. The Company used a discounted cash flow model to value its Level 3 investments, using estimates regarding recovery periods, yield, and liquidity. The assumptions used are subjective based upon management’s judgment and views on current market conditions, and resulted in $980 of the Company’s recorded temporary impairment and $725 of the OTTI as of April 28, 2012. The use of different assumptions would result in a different valuation and related temporary impairment charge.

Changes in the fair value of the Company’s financial assets measured at fair value on a recurring basis are as follows:

The carrying value of cash equivalents approximates fair value due to the low level of risk these assets present and their relatively liquid nature, particularly given their short maturities. The Company also holds certain financial instruments that are not carried at fair value on the consolidated balance sheets, including held-to-maturity securities. Held-to-maturity securities consist of state and municipal bonds, corporate bonds, and certificates of deposit. The fair values of these debt securities are based on quoted market prices and yields for the same or similar securities, which we determined to be Level 2 inputs. As of April 28, 2012, the fair value of held-to-maturity securities was $49,485 compared to the carrying amount of $49,235. As of January 28, 2012, the fair value of held-to-maturity securities is $47,595 compared to the carrying amount of $47,236.
