Earnings Per Share [Abstract] |
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 and upon exercise of outstanding stock options, using the treasury stock method. The following table presents the calculation of basic and diluted EPS (in thousands, except per share amounts):
