Income Taxes [Abstract]
INCOME TAXES	NOTE 4: INCOME TAXES Our income tax provision and the corresponding annual effective tax rate are based on expected income, statutory tax rates and tax planning opportunities available in the various jurisdictions in which we operate. For interim financial reporting, except in circumstances as described in the following paragraph, we estimate the annual effective tax rate based on projected taxable income for the full year and record a quarterly tax provision in accordance with the expected annual effective tax rate. As the year progresses, we refine the estimates of the year’s taxable income as new information becomes available, including year-to-date financial results. This continual estimation process often results in a change to our expected annual effective tax rate for the year. When this occurs, we adjust the income tax provision during the quarter in which the change in estimate occurs so that the year-to-date income tax provision reflects the expected annual effective tax rate. Significant judgment is required in determining our annual effective tax rate and in evaluating our tax positions. When application of the expected annual effective tax rate distorts the financial results of an interim period, we calculate the income tax provision or benefit using an alternative methodology. This alternative methodology results in an income tax provision or benefit based solely on the year-to-date pretax income or loss as adjusted for permanent differences on a pro rata basis. We recognize an income tax benefit associated with an uncertain tax position when, in our judgment, it is more likely than not that the position will be sustained upon examination by a taxing authority. For a tax position that meets the more-likely-than-not recognition threshold, we initially and subsequently measure the income tax benefit as the largest amount that we judge to have a greater than 50% likelihood of being realized upon ultimate settlement with a taxing authority. Our liability associated with unrecognized tax benefits is adjusted periodically due to changing circumstances, such as the progress of tax audits, case law developments and new or emerging legislation. Such adjustments are recognized entirely in the period in which they are identified. We consider resolution for an issue to occur at the earlier of settlement of an examination, the expiration of the statute of limitations, or when the issue is effectively settled. Our income tax provision includes the net impact of changes in the liability for unrecognized tax benefits and subsequent adjustments as we consider appropriate. In the first quarter of 2011, we applied the alternative methodology discussed above in the determination of the income tax benefit from continuing operations. However, as of June 30, 2011, the conditions requiring the alternative methodology no longer existed. As a result, in the second quarter of 2011, we estimated the annual effective tax rate based on our projected taxable loss for the full year and recorded a quarterly tax benefit in accordance with the expected annual effective tax rate. We recorded income tax benefits from continuing operations of $40,341,000 in the second quarter of 2011 compared to $21,231,000 in the second quarter of 2010. An adjustment to the current quarter’s income tax benefit was required so that the year-to-date benefit reflects the expected annual effective tax rate. The increase in our income tax benefit resulted largely from applying the alternative methodology in the second quarter of 2010. We recorded income tax benefits from continuing operations of $77,771,000 for the six months ended June 30, 2011 compared to $55,444,000 for the six months ended June 30, 2010. The increase in our income tax benefit resulted largely from applying the alternative methodology for the first six months of 2010.

NOTE 4: INCOME TAXES

Our income tax provision and the corresponding annual effective tax rate are based on expected income, statutory tax rates and tax planning opportunities available in the various jurisdictions in which we operate. For interim financial reporting, except in circumstances as described in the following paragraph, we estimate the annual effective tax rate based on projected taxable income for the full year and record a quarterly tax provision in accordance with the expected annual effective tax rate. As the year progresses, we refine the estimates of the year’s taxable income as new information becomes available, including year-to-date financial results. This continual estimation process often results in a change to our expected annual effective tax rate for the year. When this occurs, we adjust the income tax provision during the quarter in which the change in estimate occurs so that the year-to-date income tax provision reflects the expected annual effective tax rate. Significant judgment is required in determining our annual effective tax rate and in evaluating our tax positions.

When application of the expected annual effective tax rate distorts the financial results of an interim period, we calculate the income tax provision or benefit using an alternative methodology. This alternative methodology results in an income tax provision or benefit based solely on the year-to-date pretax income or loss as adjusted for permanent differences on a pro rata basis.
