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

(in thousands)	2012	2011
Weighted average shares outstanding:
Weighted average common stock outstanding	38,667	38,712
Less: weighted average unvested restricted stock outstanding	402	749
Total basic weighted average shares outstanding	38,265	37,963

Diluted weighted average shares outstanding:

¹Due to the net loss for the quarters ended March 31, 2012 and 2011, restricted stock units representing approximately 474,000 and 242,000 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.
