Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Our effective tax rate was 25.3% and 74.3% for the three and six months ended June 30, 2011, respectively, and was 248.5% and 7.4% for the three and six months ended June 30, 2010, respectively. The changes from prior year 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 six months ended June 30, 2011 is the recognition and measurement of previously unrecognized tax benefits, partially offset by an immaterial adjustment related to prior periods, both of which are considered discrete items 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 six months ended June 30, 2010 was affected by non-taxable life insurance proceeds which were considered a discrete item for tax provision purposes.
