Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Our effective tax rate was 26.3% and 22.5% for the three and nine months ended September 30, 2011, respectively, and was (22.8)% and 135.4% for the three and nine months ended September 30, 2010, respectively. The changes from prior year periods were primarily due to the effect from noncontrolling interests as a percent of net income (loss), as noncontrolling interests are not subject to income taxes on a stand-alone basis. Included in the tax rate for the nine months ended September 30, 2011 is the recognition and measurement of previously unrecognized tax benefits, which is considered a discrete item for tax provision purposes. The recognition and measurement of these tax benefits was the result of a favorable settlement of an income tax examination conducted by the Internal Revenue Service. In addition, our effective tax rate for the nine months ended September 30, 2010 was affected by non-taxable life insurance proceeds which were considered a discrete item for tax provision purposes.
