	(in millions)
Numerator:
Net income	$	179	$	230
Denominator:
Basic weighted-average shares	347		348
Potentially dilutive common stock equivalents — stock options and other employee stock plans	5		4
Diluted weighted-average shares	352		352

The dilutive effect of share-based awards is reflected in diluted net income per share by application of the treasury stock method, which includes consideration of unamortized share-based compensation expense, the tax benefits or shortfalls recorded to additional paid-in capital and the dilutive effect of in-the-money options and non-vested restricted stock units. Under the treasury stock method, the amount the employee must pay for exercising stock options and unamortized share-based compensation expense and tax benefits or shortfalls collectively are assumed proceeds to be used to repurchase hypothetical shares. An increase in the fair market value of the company's common stock can result in a greater dilutive effect from potentially dilutive awards.

We exclude stock options with exercise prices greater than the average market price of our common stock from the calculation of diluted earnings per share because their effect would be anti-dilutive. For the three months ended January 31, 2013, options to purchase 5,600 shares were excluded from the calculation of diluted earnings per share as compared to 1,700,000 shares for the three months ended January 31, 2012. In addition, we also exclude from the calculation of diluted earnings per share, stock options, ESPP, LTPP and restricted stock awards whose combined exercise price, unamortized fair value and excess tax benefits or shortfalls collectively were greater than the average market price of our common stock because their effect would also be anti-dilutive.  For the three months ended January 31, 2013 we excluded an additional 20,000 shares as compared to 2,000,000 shares for the three months ended January 31, 2012.
