8. Income Taxes

Internal Revenue Service (IRS) examinations have been completed and settled for all years prior to 2005, and the statute of limitations bars any additional tax assessments. The IRS has completed their examinations and issued notices of deficiency for tax years 2005 through 2010. We disagree with many of their proposed adjustments, and we are at IRS Appeals for those years. Additionally, several state tax authorities are examining our state income tax returns for years 2006 through 2010.

In the fourth quarter of 2013, we reached an agreement in principle with the IRS to resolve all of the issues related to tax years 2005 through 2008, with the exception of interest calculations. We anticipate signing a closing agreement with the IRS for these years within the next 12 months. When signed, this closing agreement will not have a material effect on our consolidated results of operations, financial condition or liquidity.

At June 30, 2014, we had a net liability for unrecognized tax benefits of $61 million. Of that amount, $26 million is classified as a current liability in the Condensed Consolidated Statements of Financial Position.
