The following data shows the amounts used in computing (loss) per share and the effect on earnings and the weighted average number of shares of dilutive potential common shares.

Basic loss per share is computed as net income available to common shareholders divided by the weighted average basic shares outstanding. The outstanding shares used to calculate the weighted average basic shares excludes 194,587 and 445,829 of restricted shares at June 30, 2020 and 2019, respectively, as these shares were issued but were not vested and therefore, not considered outstanding for purposes of computing basic loss per share at the balance sheet dates.

Diluted loss per share includes the effect of all potentially dilutive securities on earnings per share. We have stock options, stock-settled appreciation rights ("SSARs"), unvested restricted shares and unvested performance shares that are potentially dilutive securities. When a loss is reported, the denominator of diluted earnings per share cannot be adjusted for the dilutive impact of share-based compensation awards because doing so would be anti-dilutive. Therefore, for all periods presented, basic weighted average shares outstanding were used in calculating the diluted net loss per share.
