Income Taxes [Abstract]
Income Tax Disclosure [Text Block]	INCOME TAXES We are required to adjust our effective tax rate each quarter to consistently estimate our annual effective tax rate. We must also record the tax impact of certain discrete items, unusual or infrequently occurring, including changes in judgment about valuation allowances and effects of changes in tax laws or rates, in the interim period in which they occur. In addition, jurisdictions with a projected loss for the year or a year-to-date loss where no tax benefit can be recognized are excluded from the estimated annual effective tax rate. The impact of such an exclusion could result in a higher or lower effective tax rate during a particular quarter, based upon the mix and timing of actual earnings versus annual projections. Income tax expense was $2.3 million in the three months ended September 30, 2011 and $4.2 million in the first nine months of 2011 as compared to $0.8 million in the three months ended September 30, 2010 and $5.2 million in the first nine months of 2010. Our effective income tax rate was 9.3% in the third quarter of 2011 and 3.8% in the first nine months of 2011 as compared to 2.0% in the third quarter of 2010 and 6.1% in the first nine months of 2010. Our income tax expense and effective tax rate for the three months ended September 30, 2011 reflects the effect of utilizing the net operating loss in the U.S. and recording a valuation allowance against income tax benefits in certain foreign jurisdictions. Our income tax expense for the nine months ended September 30, 2011 reflects net tax benefits of $2.8 million relating to the favorable resolution of income tax audits and the reversal of state deferred tax liabilities due to newly enacted Michigan tax legislation. Our income tax expense and effective tax rate for the three and nine months ended September 30, 2010 reflected the effect of recording a valuation allowance against income tax benefits on U.S. losses. In conjunction with the filing of our 2009 federal tax return, under provisions contained in the American Recovery and Reinvestment Act of 2009, we recorded a tax benefit of $1.4 million in the three and nine months ended September 30, 2010 attributable to the monetization of alternative minimum tax and research and development credits. In the second quarter of 2011, we settled our 2004 through 2007 U.S. federal income tax audits. As a result of the settlement, in addition to a favorable tax benefit adjustment of $1.3 million included above, our gross unrecognized tax benefits were reduced by $28.7 million, our deferred tax assets were reduced by $22.3 million and our income tax payable increased by $5.1 million.

INCOME TAXES

We are required to adjust our effective tax rate each quarter to consistently estimate our annual effective tax rate. We must also record the tax impact of certain discrete items, unusual or infrequently occurring, including changes in judgment about valuation allowances and effects of changes in tax laws or rates, in the interim period in which they occur. In addition, jurisdictions with a projected loss for the year or a year-to-date loss where no tax benefit can be recognized are excluded from the estimated annual effective tax rate. The impact of such an exclusion could result in a higher or lower effective tax rate during a particular quarter, based upon the mix and timing of actual earnings versus annual projections.

Income tax expense was $2.3 million in the three months ended September 30, 2011 and $4.2 million in the first nine months of 2011 as compared to $0.8 million in the three months ended September 30, 2010 and $5.2 million in the first nine months of 2010. Our effective income tax rate was 9.3% in the third quarter of 2011 and 3.8% in the first nine months of 2011 as compared to 2.0% in the third quarter of 2010 and 6.1% in the first nine months of 2010.
