Numerator: |  |  |  |  |  |  |  |  |
Net income | $ | 91 |  |  | $ | 70 |  |  | $ | 243 |  |  | $ | 236 |
Denominator: |  |  |  |  |  |  |
Basic weighted-average shares | 170 |  |  | 169 |  |  | 170 |  |  | 169 |
Potential common shares— stock options and other employee stock plans | 2 |  |  | 3 |  |  | 2 |  |  | 2 |
Diluted weighted-average shares | 172 |  |  | 172 |  |  | 172 |  |  | 171 |
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 the effect would be anti-dilutive. For both the three and nine months ended July 31, 2016, 1.7 million options to purchase shares were excluded from the calculation of diluted earnings per share. In addition, we excluded stock options, ESPP shares, LTP Program and restricted stock awards, of which the combined exercise price, unamortized fair value and excess tax benefits or shortfalls collectively was greater than the average market price of our common stock because the effect would be anti-dilutive. For the three and nine months ended July 31, 2016, we excluded 17,700 and 21,300 shares, respectively.
