Net income (loss) per share

9. Net Income (Loss) per Share

Net income (loss) per share is based upon the net income (loss) divided by weighted average number of shares outstanding during the period. Common stock options and restricted stock rights/units are converted using the treasury stock method.

Basic and diluted net income (loss) per share has been computed as follows (in thousands, except per-share amounts):

	Three months ended June 30,				Six months ended June 30,
	2013		2012		2013			2012
Income (loss) from operations, net of income taxes	$	438	$	4,282	$	(331	)	$	2,418
Weighted average shares outstanding		8,858		8,874		8,829			8,860
Weighted effect of dilutive options and rights		97		54		—			76
Weighted average shares outstanding assuming dilution		8,955		8,928		8,829			8,936
Net income (loss) per share:
Basic	$	0.05	$	0.48	$	(0.04	)	$	0.27
Diluted	$	0.05	$	0.48	$	(0.04	)	$	0.27

For the three months ended June 30, 2013, the effect of two restricted stock rights/units and options to purchase 41,143 shares are excluded from the calculation of weighted average shares outstanding because such rights/units and options were anti-dilutive. For the six months ended June 30, 2013, the effect of 157,342 restricted stock rights/units and options to purchase 251,130 shares are excluded from the calculation of weighted average shares outstanding because such rights/units and options were anti-dilutive.

For the three months ended June 30, 2012, the effect of zero restricted stock rights/units and options to purchase 263,740 shares are excluded from the calculation of weighted average shares outstanding because such rights/units and options were anti-dilutive. For the six months ended June 30, 2012, the effect of zero restricted stock rights/units and options to purchase 257,257 shares are excluded from the calculation of weighted average shares outstanding because such rights/units and options were anti-dilutive.
