The company’s effective tax rate from continuing operations was 4.2 percent and 11.5 percent for the three and six months ended April 30, 2015, respectively.

The income tax provision from continuing operations for the three and six months ended April 30, 2016 included net discrete tax expense of $3 million and tax benefit of $3 million, respectively. The net discrete tax expense for the three months ended April 30, 2016 included a tax expense of $7 million for return-to-provision adjustments associated with the filing of the return in Germany, $5 million of which was determined to be out of period. The remaining discrete items in the quarter include an $8 million tax benefit related to the realization of tax credits that reduce the deferred tax liability for unremitted foreign earnings, $2 million tax expense of other miscellaneous return-to-provision adjustments in other foreign jurisdictions and $2 million of miscellaneous other discrete tax expense. The out of period adjustment is a true up of a deferred tax asset related to a net operating loss carryover that was recorded in 2006 using an incorrect income tax rate.

The out of period adjustment is not considered to be material to current or prior periods. The income tax provision from continuing operations for the three and six months ended April 30, 2015 included net discrete benefits of $13 million and $16 million, respectively. The net discrete tax benefit for the three months ended April 30, 2015 included $16 million of tax benefit related to the de-registration of certain foreign branches, and $3 million of other discrete tax expense.

In the U.S., tax years remain open back to the year 2012 for federal income tax purposes and the year 2000 for significant states. On September 22, 2015, we reached an agreement with the Internal Revenue Service ("IRS") for the tax years 2008 through 2011. During the first quarter of 2016, we made a payment of approximately $9 million of tax plus interest as part of closing the exam. In 2015, we reclassified a portion of other long-term liabilities to other accrued liabilities related to uncertain tax positions of continuing operations that we expected to pay within the next twelve months. This amount was partially offset by a prepaid tax account of approximately $3 million that the IRS allowed as an offset to the $12 million in incremental taxes. The settlement resulted in the recognition, within the continuing operations, of previously unrecognized tax benefits of $119 million, offset by a tax liability on foreign distributions of approximately $99 million principally related to the repatriation of foreign earnings. In other major jurisdictions where the company conducts business, the tax years generally remain open back to the year 2003. With these jurisdictions and the U.S., it is reasonably possible that there could be significant changes to our unrecognized tax benefits in the next twelve months due to either the expiration of a statute of limitation or a tax audit settlement which will be partially offset by an anticipated tax liability related to unremitted foreign earnings, where applicable. Given the number of years and numerous matters that remain subject to examination in various tax jurisdictions, management is unable to estimate the range of possible changes to the balance of our unrecognized tax benefits. On July 27, 2015, the U.S. Tax Court issued an opinion in Altera Corp. v. Commissioner related to the treatment of stock-based compensation expense in an intercompany cost-sharing arrangement. A final decision was entered by the U.S. Tax Court on December 1, 2015. At this time, the U.S. Department of the Treasury has not withdrawn the requirement from its regulations to include stock-based compensation in an intercompany cost-sharing arrangement. The IRS notified the U.S. Court of Appeals for the Ninth Circuit on February 19, 2016 of its intent to appeal the Tax Court's decision in the case.
