11. EARNINGS PER SHARE

Basic earnings per share is calculated by dividing net income by the weighted average number of shares outstanding during the applicable period. If the number of common shares outstanding increases as a result of a stock dividend or stock split or decreases as a result of a reverse stock split, the computations of basic and diluted earnings per share are adjusted retroactively for all periods presented to reflect that change in capital structure. If such changes occur after the close of the reporting period but before issuance of the financial statements, the per-share computations for that period and any prior-period financial statements presented are based on the new number of shares.

The Company has issued stock options and restricted stock units, which are considered to be potentially dilutive to its basic earnings per share. Diluted earnings per share is calculated using the treasury stock method for the dilutive effect of options and restricted stock units granted pursuant to the stock option and incentive plan, by dividing the net income by the weighted average number of shares outstanding during the period adjusted for these potentially dilutive options, except when the results would be anti-dilutive. The potential tax benefit on exercise of stock options is considered as additional proceeds while computing dilutive earnings per share using the treasury stock method.

The following tables set forth the computation of earnings per share:
