14.	Net Income (Loss) Per Share

Net income (loss) per share is presented in accordance with authoritative guidance which requires the presentation of “basic” and “diluted” earnings per share. Basic net income (loss) per share is computed by dividing earnings available to common shareholders by the weighted average shares of common stock outstanding during the period. For the purposes of calculating diluted net income (loss) per share, the denominator includes both the weighted average number of shares of common stock outstanding during the period and the weighted average number of shares of potential dilutive shares of common stock, such as stock awards, calculated using the treasury stock method. Basic and diluted net income (loss) per share was the same for fiscal 2017 and 2016 as the impact of potential dilutive shares outstanding was anti-dilutive.

The following table sets forth our computation of basic and diluted net income (loss) per common share (amounts in thousands, except per share data):

	For the Fiscal Years Ended January 31,
	2018		2017			2016
Net income (loss)	$	13,498	$	(71,249	)	$	(47,697	)

Weighted average shares used in computing net income (loss) per share - basic		35,412		34,970			33,506
Effect of dilutive shares:
Stock options		60		—			—
Restricted stock units		63		—			—
Deferred stock units		84		—			—
Performance stock units		66		—			—
Dilutive potential common shares		273		—			—
Weighted average shares used in computing net income (loss) per share - diluted		35,685		34,970			33,506

Net income (loss) per share:
Basic	$	0.38	$	(2.04	)	$	(1.42	)
Diluted	$	0.38	$	(2.04	)	$	(1.42	)

The number of common shares used in the computation of diluted net income (loss) per share for the periods presented does not include the effect of the following potentially outstanding common shares because the effect would have been anti-dilutive (amounts in thousands):

	For the Fiscal Year Ended January 31,
	2018		2017		2016
Stock options		1,522		1,415		1,493
Restricted stock units		159		448		145
Deferred stock units		13		70		31
Performance stock units		297		318		5
Total		1,991		2,251		1,674
