[1] Fair values are determined based on valuation techniques categorized as follows: Level 1 means the use of quoted prices for identical instruments in active markets; Level 2 means the use of quoted prices for similar instruments in active markets or quoted prices for identical or similar instruments in markets that are not active or are directly or indirectly observable; Level 3 means the use of unobservable inputs. All of our financial assets and liabilities measured at fair value on a recurring basis use Level 2 inputs in the calculation of fair value, except that included in available-for-sale equity securities, excluding money market funds, are $84 million as of October 2, 2011 and $105 million as of December 31, 2010 of investments that use Level 1 inputs in the calculation of fair value and $26 million that use Level 3 inputs as of October 2, 2011.
