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 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 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 and six months ended April 30, 2017, no options to purchase shares were excluded from the calculation of diluted earnings per share as compared to 2.1 million and 1.7 million options to purchase shares excluded for the three and six months ended April 30, 2016. In addition, we exclude from the calculation of diluted earnings per share stock options, ESPP, LTPP and restricted stock awards whose combined exercise price and unamortized fair value were greater than the average market price of our common stock because their effect would also be anti-dilutive. For the three and six months ended April 30, 2017, 1,000 and 500 additional shares were excluded from the calculation of diluted earnings per share as compared to 2,600 and 3,500 additional shares excluded for the three and six months ended April 30, 2016.
