Weighted Average Shares Outstanding

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 September 30,		Nine Months Ended September 30,
(in thousands)	2013	2012	2013	2012
Weighted average shares outstanding:
Weighted average common stock outstanding	38,876	38,707	38,814	38,679
Less: weighted average unvested restricted stock outstanding	—	189	41	261
Total basic weighted average shares outstanding	38,876	38,518	38,773	38,418
Diluted weighted average shares outstanding:
Weighted average common stock outstanding, basic	38,876	38,518	38,773	38,418
Effect of dilutive securities:
Common stock options and restricted stock units1	883	623	—	595
Total weighted average shares outstanding assuming dilution	39,759	39,141	38,773	39,013

¹Due to the net loss for the nine months ended September 30, 2013, restricted stock units and common stock options representing approximately 863,000 have been excluded from the number of shares used in calculating diluted net loss per share, as their inclusion would be antidilutive.
