NET INCOME (LOSS) PER SHARE

Note 17    NET INCOME (LOSS) PER SHARE

        Basic net income (loss) per share is calculated by using the weighted-average number of common shares outstanding during that period. Diluted net income (loss) per share is calculated giving effect to all dilutive potential common shares that were outstanding during the period. Dilutive potential common shares consist of incremental common shares issuable upon exercise of stock options, upon vesting of restricted stock units, contingent issuable shares for all periods and accrued issuance of shares under employee stock purchase plan. No dilutive potential common shares were included in the computation of any diluted per share amount when a loss from continuing operations was reported by the Company.

        A reconciliation of the numerator and denominator of basic and diluted net income (loss) per share is provided as follows:
