Earnings Per Share

The following table sets forth the computation of earnings per share for the periods indicated. Basic net income per share has been computed using the weighted average number of shares of common stock outstanding during the period. Diluted net income per share has been computed using the weighted average number of common shares outstanding during the period plus dilutive potential shares of common stock from (1) stock options, performance and restricted shares (under the treasury stock method) and (2) convertible debt (under the If Converted method) outstanding during the period.
