Income Taxes [Abstract]
Income Taxes [Text Block]	Income Taxes At March 31, 2012, our unrecognized tax benefits were $159.3 million. Of this amount, approximately $61.7 million would affect our effective tax rate upon resolution of the uncertain tax positions. Our effective tax rate for the first quarter of 2012 increased to 32.8%, compared to 25.5% for the first quarter of 2011. Income tax expense for the three months ended March 31, 2011 includes a $39.5 million tax benefit related to charges incurred in connection with our repositioning actions, a provision of $2.8 million related to the remeasurement gain and a provision of $9.0 million for agreed upon adjustments to income tax returns that were under examination in the first quarter of 2011. Excluding the effect of these items, our effective tax rate for the quarter ended March 31, 2011 would have been 34.1%. The tax benefit on the repositioning actions was calculated based on the jurisdictions where the charges were incurred and reflects the likelihood that we will be unable to obtain a tax benefit for all charges incurred. The remeasurement gain resulting from the acquisition of the controlling interest in Clemenger created a difference between the book basis and tax basis of our investment. Because this basis difference is not expected to reverse, no deferred taxes were provided and the tax provision recorded represents the incremental U.S. tax on acquired historical unremitted earnings. The $9.0 million charge resulted from adjustments to U.S. income tax returns for calendar years 2005, 2006 and 2007, that were agreed upon and recorded in the first quarter of 2011. The examination of those returns is closed.

Income Taxes

At March 31, 2012, our unrecognized tax benefits were $159.3 million. Of this amount, approximately $61.7 million would affect our effective tax rate upon resolution of the uncertain tax positions.

Our effective tax rate for the first quarter of 2012 increased to 32.8%, compared to 25.5% for the first quarter of 2011. Income tax expense for the three months ended March 31, 2011 includes a $39.5 million tax benefit related to charges incurred in connection with our repositioning actions, a provision of $2.8 million related to the remeasurement gain and a provision of $9.0 million for agreed upon adjustments to income tax returns that were under examination in the first quarter of 2011. Excluding the effect of these items, our effective tax rate for the quarter ended March 31, 2011 would have been 34.1%.

The tax benefit on the repositioning actions was calculated based on the jurisdictions where the charges were incurred and reflects the likelihood that we will be unable to obtain a tax benefit for all charges incurred. The remeasurement gain resulting from the acquisition of the controlling interest in Clemenger created a difference between the book basis and tax basis of our investment. Because this basis difference is not expected to reverse, no deferred taxes were provided and the tax provision recorded represents the incremental U.S. tax on acquired historical unremitted earnings. The $9.0 million charge resulted from adjustments to U.S. income tax returns for calendar years 2005, 2006 and 2007, that were agreed upon and recorded in the first quarter of 2011.
