Earnings Per Share

Diluted EPS is calculated by dividing net income by the average common shares outstanding plus additional common shares that would have been outstanding assuming the exercise of in-the-money stock options and restricted stock units, using the treasury-stock method. For the three months ended March 31, 2013 and 2012, antidilutive shares excluded from the calculation of EPS were not material.
