4. Earnings Per Share
We compute basic earnings per share by dividing net income available to common stockholders by the weighted average number of common shares outstanding during the period. Diluted earnings per share is computed by dividing net income available to common stockholders by the weighted average number of common shares and dilutive potential common shares outstanding during the period. Diluted earnings per share reflect the assumed exercise, settlement and vesting of all dilutive securities using the “treasury stock method” except when the effect is anti-dilutive. Potentially dilutive securities consist of shares issuable upon the exercise of stock options, settlement of stock appreciation rights and vesting of restricted stock awards and units. The following table sets forth the computation of basic and diluted earnings per share:
