FAIR VALUE MEASUREMENTS

FAIR VALUE MEASUREMENTS

Assets and Liabilities Measured and Recorded at Fair Value on a Recurring Basis

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 six months ended May 30, 2014.

The fair value of our financial assets and liabilities at May 30, 2014 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 non-binding market consensus prices that are corroborated by observable market data, quoted market prices for similar instruments, or pricing models such as discounted cash flow techniques. 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.

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis

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. During the three and six months ended May 30, 2014, we determined there were no other-than-temporary impairments on our cost method investments. Comparatively, during the three and six months ended May 31, 2013, we determined there was an other-than-temporary impairment of $5.0 million on our cost method investments and wrote down the investments to fair value.

As of May 30, 2014, the carrying value of our lease receivables approximated fair value, based on Level 2 valuation inputs which include Treasury rates, LIBOR rates and applicable credit spreads. See Note 12 for further details regarding our investment in lease receivables. The fair value of our debt was $1.6 billion as of May 30, 2014, based on Level 2 quoted prices in inactive markets. See Note 13 for further details regarding our debt.
