Earnings (Loss) Per Common Share

Basic earnings (loss) per common share is computed by dividing the net income (loss) allocated to common stockholders by the weighted-average number of shares of common stock outstanding during the period. For purposes of calculating diluted earnings (loss) per common share, the denominator includes both the weighted-average number of shares of common stock outstanding during the period and the number of common stock equivalents if the inclusion of such common stock equivalents is dilutive. Dilutive common stock equivalents potentially include stock options and warrants using the treasury stock method. The following table summarizes the components of the earnings (loss) per common share calculation (in thousands, except per share amounts):

	Three Months ended				Nine Months ended

For the three and nine months ended March 31, 2016 and 2015, the Company incurred net losses which cannot be diluted; therefore, basic and diluted loss per common share is the same. As of March 31, 2016, shares issuable which could potentially dilute future earnings included approximately 12.3 million stock options and 30,000 warrants. As of March 31, 2015, shares issuable which could potentially dilute future earnings included approximately 9.7 million stock options and 6.6 million warrants.
