7.	Earnings (Loss) per Share

Beginning in the fourth quarter of fiscal 2014, basic earnings (loss) per share was computed using the two-class method. The two-class method is an earnings allocation that determines earnings per share for each class of common stock and participating securities according to dividends declared and participation rights in undistributed earnings. The Company's restricted stock awards, issued in conjunction with the Questcor Acquisition in August 2014, are considered participating securities as holders are entitled to receive non-forfeitable dividends during the vesting term. Diluted earnings per share includes securities that could potentially dilute basic earnings per share during a reporting period, which includes all share-based compensation awards other than participating securities. Dilutive securities, including participating securities, are not included in the computation of loss per share when the Company reports a net loss from continuing operations as the impact would be anti-dilutive.

Prior to the fourth quarter of fiscal 2014, basic earnings (loss) per share was computed by dividing net income by the number of weighted-average shares outstanding during the period. Diluted earnings (loss) per share was computed using the weighted-average shares outstanding and, if dilutive, potential ordinary shares outstanding during the period. Potential ordinary shares represented the incremental ordinary shares issuable for restricted share units and share option exercises. The Company calculated the dilutive effect of outstanding restricted share units and share options on earnings (loss) per share by application of the treasury stock method.
