Net Income (Loss) per Share

(4) Net Income (Loss) per Share

Basic net income (loss) per share is computed on the basis of the weighted average number of shares of common stock outstanding during the period. Diluted net income (loss) per share is computed on the basis of the weighted average number of shares of common stock plus the effect of dilutive potential common shares outstanding during the period using the treasury stock method and the if-converted method. Dilutive potential common shares include outstanding stock options and shared-based awards. Reconciliation and the components of basic and diluted net loss per share are as follows (in thousands, except per share data):

Options to purchase 539,500 shares of common stock at exercise prices ranging from $1.03 to $24.10 per share outstanding for the three months ended September 30, 2013 were not included in diluted net income per share, as the impact to diluted net income per share is anti-dilutive. Stock options are included in the calculation of diluted EPS based on the treasury-stock method. Under the treasury-stock method, options will have a dilutive effect only when the average market price of the common stock during the respective period, $0.73 for the three months ended September 30, 2013, exceeds the exercise price of the options. Options to purchase 1,205,900 shares of common stock at exercise prices ranging from $0.30 to $24.10 per share outstanding for the three months ended September 30, 2012, were not included in diluted net loss per share, as the impact to net loss per share is anti-dilutive.
