EPS denominator:
Weighted-average common stock outstanding - basic (in shares)	32,910		32,600		32,769		32,468
Common stock equivalents: stock options and other stock-based awards (a)	0	[1]	0	[1]	0	[1]	0	[1]
Weighted-average number of common stock outstanding - diluted (in shares)	32,910		32,600		32,769		32,468

[1] For the periods in which net losses are presented, the diluted weighted average number of shares of common stock outstanding did not differ from the basic weighted average number of shares of common stock outstanding because the effects of any potential common stock equivalents (see Note 6 for further details on outstanding stock options, unvested restricted stock units and unvested restricted stock) were anti-dilutive and therefore not included in the calculation of the denominator of dilutive earnings per share.
