Income Taxes [Abstract] |
Income Taxes | 10. Income Taxes We file a consolidated federal income tax return in the United States and file tax returns in various state and foreign jurisdictions. The U.S. federal consolidated tax returns for the years 1999 through 2010 are currently under examination by the Internal Revenue Service (IRS). In November 2012, we received written approval from the IRS Joint Committee on Taxation of the settlement of a majority of issues related to the examination of our 1999 through 2007 tax returns. Except for three issues for which we are pursuing refund claims for tax years 2002 through 2008, which will remain open until resolved, these years are closed. We are assessing the impact of the settlement which will reduce uncertain tax benefits by approximately $6 0 million, a majority of which will result in an income tax benefit being recorded in the third quarter of the current fiscal year. Historically, tax returns in various foreign and state jurisdictions are examined and settled upon completion of the exam. We had gross unrecognized tax benefits of $207.4 million and $206.4 million at October 31, 2012 and April 30, 2012, respectively. The gross unrecognized tax benefits increased $1.0 million net in the current year, due primarily to accruals of tax on positions related to current and prior years partially offset by settlements with taxing authorities. We believe it is reasonably possible that the balance of unrecognized tax benefits could decrease by approximately $76 million before October 31, 2013. This anticipated decrease is due primarily to the settlement of the 1999 through 2007 IRS examination. The expiration of statutes of limitations and anticipated settlements of state audit issues will also contribute to the anticipated decrease. This amount is included in accrued income taxes in our consolidated balance sheet. The remaining amount is classified as long-term and is included in other noncurrent liabilities in the consolidated balance sheet.
