Expected life of non-qualified stock options (in years) (4)6.1 5.5 5.5
(1)Forfeitures are estimated using historical experience and projected employee turnover.
(2)Based on the Treasury constant maturity interest rate whose term is consistent with the expected life of our non-qualified stock options.
(3)Beginning in fiscal 2005, we use an outside valuation advisor to assist us in projecting expected stock pricevolatility. We consider
both the historical volatility of our stock price as well as implied volatilities from exchange-traded options on our stock. Prior to fiscal
2005, expected stock price volatility was based primarily on historical experience.
(4)We estimate the expected life of non-qualified stock options based upon historicalexperience.
Net cash proceeds from the exercise of non-qualified stock
options were $257, $220 and $114 for fiscal 2006, 2005
and 2004, respectively.
The actual income taxbenefit realized from non-qualified
stock option exercises totaled $53,$59 and $41, forfiscal
2006, 2005 and 2004, respectively.
