Net Income Per Common Share

(In Thousands, Except Share Data)

Basic net income per common share is calculated by dividing net income by the weighted-average number of common shares outstanding for the period. Diluted net income per common share reflects the pro forma dilution of shares outstanding, assuming outstanding service-based restricted stock awards fully vested and outstanding stock options were exercised into common shares, calculated in accordance with the treasury method. Basic and diluted net income per common share calculations are as follows for the periods presented:
