A reconciliation of the weighted average shares outstanding used in calculating basic and diluted net income (loss) per share in the accompanying condensed consolidated statements of operations is as follows:



	Three Months Ended June 30,		Six Months Ended June 30,
(in thousands)	2013	2012	2013	2012
Weighted average shares outstanding:
Weighted average common stock outstanding	38,829	38,664	38,782	38,666
Less: weighted average unvested restricted stock outstanding	—	193	62	298
Total basic weighted average shares outstanding	38,829	38,471	38,720	38,368

Diluted weighted average shares outstanding:
Weighted average common stock outstanding, basic	38,829	38,471	38,720	38,368

Common stock options and restricted stock units¹	940	680	—	—
Total weighted average shares outstanding assuming dilution	39,769	39,151	38,720	38,368

¹Due to the net loss for the six months ended June 30, 2013 and 2012, restricted stock units and common stock options representing approximately 851,000 and 580,000 shares, respectively, have been excluded from the number of shares used in calculating diluted net loss per share for the respective periods, as their inclusion would be antidilutive.
