| Net (Loss) Income Per Share |
3. Net (Loss) Income Per Share
Our basic net (loss) income per share amounts have been computed by dividing net (loss) income by the weighted-average number of common shares outstanding during the period. For the current reporting periods, we reported net losses and, accordingly, potential common shares were not included since such inclusion would have been anti-dilutive. For the corresponding periods of 2014, we reported net income, and the computation of diluted earnings per share is based upon the weighted-average number of our common shares and dilutive effect of stock options (determined using the treasury stock method) and contingent consideration liability (arising from our 2013 acquisition of Molecular Insight). The calculations of net (loss) income per share, basic and diluted, are as follows:
