9. Earnings Per Share
Basic earnings per share of common stock is computed by dividing net income by the weighted average number of common shares outstanding during the period. Diluted earnings per share of common stock is computed by dividing net income by the weighted average number of common shares and common stock equivalents related to the assumed exercise of stock options, using the two-class method. Stock options for which the exercise price exceeds the average fair value have an anti-dilutive effect on earnings per share and are excluded from the calculation.
As restricted shares participate in dividends, in accordance with Accounting Standards Codification Topic (“ASC”) 260, the Company has calculated earnings per share pursuant to the two-class method, which is an earnings allocation formula that determines earnings per share for common stock and participating securities according to dividends declared and participation rights in undistributed earnings. Under this method, all earnings (distributed and undistributed) are allocated to common shares and participating securities based on their respective rights to receive dividends.
