Income Taxes [Abstract]
Income Taxes [Text Block]	Income Taxes Our effective tax rate for the six months ended June 30, 2012 and 2011 was 33.7% and 30.9%, respectively. The effective tax rate for the six months ended June 30, 2011 was impacted by the following items. In connection with the acquisition of a controlling interest in the Clemenger Group increasing our equity ownership to 73.7% from 46.7%, effective February 1, 2011, we recorded a remeasurement gain of $123.4 million and a related tax provision of $2.8 million. In addition, in the first quarter of 2011, in connection with a continuing review of our businesses focused on enhancing our strategic position, improving our operations and rebalancing our workforce, we recorded $131.3 million of charges and a related tax benefit of $39.5 million related to repositioning actions for severance, real estate lease terminations and asset and goodwill write-offs related to disposals and other costs. Income tax expense for the six months ended June 30, 2011 also included 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 six months ended June 30, 2011 would have been 34.2%. 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 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 $9.0 million charge resulted from adjustments to U.S. income tax returns for calendar years 2005, 2006 and 2007, which were agreed upon and recorded in the first quarter of 2011. The examination of those returns is closed. At June 30, 2012, our unrecognized tax benefits were $157.2 million. Of this amount, approximately $60.0 million would affect our effective tax rate upon resolution of the uncertain tax positions.
