EARNINGS PER SHARE CALCULATION EARNINGS PER SHARE CALCULATION
Basic net income per common share (“Basic EPS”) is computed using the weighted average number of common shares outstanding. Diluted net income per potential common share (“Diluted EPS”) is computed using the weighted average number of the following, in each case, to the extent that the effect is not anti-dilutive: (i) common shares outstanding; (ii) shares issuable upon vesting of stock unit awards; and (iii) shares issuable under Ciena’s employee stock purchase plan, using the treasury stock method.
The following table presents the calculation of Basic EPS and Diluted EPS for the periods indicated (in thousands, except per share amounts):
