NET INCOME (LOSS) PER SHARE

Calculations of the basic and diluted net income (loss) per share and potential common shares are as follows (in thousands, except for per share data):

Diluted net income (loss) per share	$	0.90	$	0.36	$	(0.35	)

The following table sets forth options and restricted stock units excluded from the calculation of diluted net income per share, since their inclusion would be antidilutive (in thousands):

Basic net income (loss) per share is calculated by dividing net income (loss) by the weighted average number of shares outstanding during the period. Unvested restricted shares, although legally issued and outstanding, are not considered outstanding for purposes of calculating basic earnings per share. Diluted net income (loss) per share is calculated by dividing net income (loss) by the weighted average number of shares outstanding plus the dilutive effect, if any, of outstanding restricted shares and restricted stock units using the treasury stock method. The calculation of the dilutive effect of outstanding equity awards under the treasury stock method includes consideration of proceeds from the assumed exercise of unrecognized compensation expense. As we incurred a net loss in the fiscal year ended March 31, 2016, all outstanding restricted stock units have an anti-dilutive effect and are therefore excluded from the computation of diluted weighted average share outstanding.

The delivery of 7.4 million shares under the Company's accelerated share repurchase (ASR) agreements reduced our outstanding shares used to determine our weighted average common shares outstanding for purposes of calculating basic and diluted earnings per share for the fiscal year ended March 31, 2018. See Note 13 for additional information. We evaluated the ASR agreements for potential dilutive effects of any shares remaining to be received or owed upon settlement and determined the additional shares to be received would be anti-dilutive, and therefore they were not included in our calculation of diluted earnings per share for the fiscal year ended March 31, 2018.
