Since the Company was in a net loss position for the nine months ended June 30, 2017, there was no difference between the number of shares used to calculate basic and diluted loss per share. Because of their anti-dilutive effect, 8,824 common share equivalents, comprised of employee stock options, have been excluded from the diluted EPS calculation for the nine months ended June 30, 2017.
