Earnings per share

The Company is required to present basic earnings per share and diluted earnings per share in accordance with ASC 260. Earnings per share are based on the weighted average number of shares outstanding during the period after consideration of the dilutive effect, if any, for common stock equivalents, including stock options and restricted share units. Basic earnings per common share are computed by dividing net income available to common shareholders by the weighted average number of shares of common stock outstanding during the period. Diluted earnings per common share are computed by dividing net income by the weighted average number of shares of common stock outstanding and dilutive securities outstanding during the period under the treasury method.
