NOTE B — EARNINGS PER SHARE

Basic earnings per common share is computed using the weighted average number of common shares outstanding during the period. Diluted earnings per common share is computed using the weighted average number of common shares outstanding during the period plus any potentially dilutive common shares, such as stock options, restricted stock units, and performance-based units calculated using the treasury stock method. Total anti-dilutive shares excluded from the diluted earnings per share were zero as of March 31, 2019 and 208,510 as of March 31, 2018.

Our credit agreement restricts the payment of dividends or other distributions to our shareholders with respect to Hanger, Inc., or any of its subsidiaries.

The reconciliation of the numerators and denominators used to calculate basic and diluted net loss per share are as follows:
