Basic earnings per share was computed by dividing net income by the weighted average number of shares of common stock outstanding during the year. Diluted earnings per share was determined based on the dilutive effect of share-based awards using the treasury stock method.

Options to purchase shares of common stock that were outstanding at the end of the respective periods, but were not included in the computation of diluted earnings per share because the effect of exercising such options would be antidilutive, were 1.3 million, 1.2 million, and 1.2 million in 2015, 2014 and 2013, respectively.
