Basic earnings per share is computed by dividing net income by the weighted average number of shares of common stock outstanding during the period. Diluted earnings per share is determined based on the dilutive effect of stock options 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 1.0 million and 0.3 million in the 2012 and 2011 periods, respectively.
