Income Taxes
P. The effective tax rate was 61 percent for the nine months ending September 30, 2012 primarily due to losses in certain jurisdictions providing no tax benefit and an increase in the valuation allowance related to net operating losses. This effective tax rate includes a $21 million state income tax benefit resulting from the decrease in the liability for uncertain tax positions primarily from the expiration of applicable statutes of limitations in various jurisdictions and certain audit closings.

As a result of tax audit closings, settlements and expiration of applicable statutes of limitations in various jurisdictions within the next 12 months, the Company anticipates that it is reasonably possible that the liability for uncertain tax positions could be reduced by approximately $3 million.
