Earnings Per Share [Abstract]

Income (Loss) Per Share

INCOME (LOSS) PER SHARE

Basic income (loss) per share was computed using the weighted average number of common shares outstanding. For the computation of diluted income (loss) per share, the number of basic weighted average shares outstanding was increased by dilutive potential common shares related to stock-based compensation, as determined by the treasury stock method. The weighted average numbers of shares outstanding used to compute income (loss) per share were as follows:

	As of December 31,
(Number of shares in thousands)	2011	2010
Basic weighted average shares outstanding	30,746	30,744
Dilutive potential common shares	30	—	(1)
Diluted weighted average shares outstanding	30,776	30,744
(1) Dilutive potential shares omitted due to net loss		26

The weighted average numbers of shares outstanding listed in the table below were anti-dilutive and excluded from the computation of diluted income (loss) per share, primarily because the average market price did not exceed the exercise price. These shares may be dilutive potential common shares in the future.
