FAIR VALUE MEASUREMENTS

FAIR VALUE MEASUREMENTS

Financial Assets and Liabilities

We measure certain financial assets and liabilities at fair value on a recurring basis. There have been no transfers between fair value measurement levels during the three months ended March 2, 2012.

The fair value of our financial assets and liabilities at March 2, 2012 was determined using the following inputs (in thousands):

See Note 3 for further information regarding the fair value of our financial instruments.

Our fixed income available-for-sale securities consist of high quality, investment grade securities from diverse issuers with a minimum credit rating of BBB and a weighted average credit rating of AA-. We value these securities based on pricing from pricing vendors, who may use quoted prices in active markets for identical assets (Level 1 inputs) or inputs other than quoted prices that are observable either directly or indirectly (Level 2 inputs) in determining fair value. However, we classify all of our fixed income available-for-sale securities as having Level 2 inputs. The valuation techniques used to measure the fair value of our financial instruments having Level 2 inputs were derived from pricing models that use non-binding market consensus prices that are corroborated by observable market data or quoted prices for similar instruments. Our procedures include controls to ensure that appropriate fair values are recorded such as comparing prices obtained from multiple independent sources. 

Our deferred compensation plan assets consist of prime money market funds and mutual funds.

Direct Investments

We also have direct investments in privately held companies accounted for under the cost method, which are periodically assessed for other-than-temporary impairment. If we determine that an other-than-temporary impairment has occurred, we write-down the investment to its fair value. We estimate fair value of our cost method investments considering available information such as pricing in recent rounds of financing, current cash positions, earnings and cash flow forecasts, recent operational performance and any other readily available market data. Our cost method investments as of March 2, 2012 and December 2, 2011 were $21.4 million and $21.0 million, respectively. For the three months ended March 2, 2012, we determined there were no other-than-temporary impairments on our cost method investments.
