Earnings (Loss) per Share
Basic earnings per common share is computed by dividing net income available to common stockholders by the weighted average number of common shares outstanding during the period, excluding the effects of any potentially dilutive securities. Diluted earnings per common share gives effect to all dilutive potential of shares of common stock outstanding during the period including stock options or warrants, using the treasury stock method (by using the average stock price for the period to determine the number of shares assumed to be purchased from the exercise of stock options or warrants), and convertible debt or convertible preferred stock, using the if-converted method. Earnings per share excludes all potential dilutive shares of common stock if their effect is anti-dilutive. There were no potential dilutive securities outstanding during the three months ended October 31, 2012 or 2011.
