Subsequent Events [Abstract]
Subsequent Events [Text Block]	Subsequent Event On January 19, 2012, we adopted a plan to restructure our workforce in part to enhance profitability and in part in connection with an organizational realignment of our business. We expect to record a restructuring charge of approximately $20 million in the second quarter of 2012 for severance and related costs associated with a workforce reduction of approximately 3%. Cash expenditures of the same amount are expected to be paid by the end 2012. As of the end of the first quarter of 2012, we had 6,110 employees worldwide.
