(4) LOSS PER SHARE

Basic loss per share is computed by dividing net loss by the weighted-average number of common shares outstanding during the period. Diluted loss per share is computed by dividing net loss by the weighted-average number of common shares outstanding and the number of dilutive potential common share equivalents during the period, calculated using the treasury-stock method. For the three and six months ended June 30, 2016 and 2015, the potential common stock equivalents totaled 2,488,250 and 1,267,500, respectively, and were excluded from the dilutive loss per share calculation as their impacts were antidilutive.
