Note 6 — Income Taxes
The effective tax rate was 13.1% and 17.9% for the nine months ended February 28, 2017 and February 29, 2016, respectively. The decrease in the Company's effective tax rate was primarily due to a discrete benefit related to the resolution of a foreign tax credit matter with the U.S. Internal Revenue Service (IRS). The Company also benefited from a reduction in tax reserves related to foreign operations. As of February 28, 2017, total gross unrecognized tax benefits, excluding related interest and penalties, were $421 million, $183 million of which would affect the Company’s effective tax rate if recognized in future periods. As of May 31, 2016, total gross unrecognized tax benefits, excluding related interest and penalties, were $506 million. The liability for payment of interest and penalties decreased $36 million during the nine months ended February 28, 2017. As of February 28, 2017 and May 31, 2016, accrued interest and penalties related to uncertain tax positions were $173 million and $209 million, respectively (excluding federal benefit). The Company incurs tax liabilities primarily in the United States, China and the Netherlands, as well as various state and other foreign jurisdictions. The Company is currently under audit by the IRS for fiscal years 2013 through 2016. As previously disclosed, the Company received statutory notices of deficiency for fiscal 2011 and fiscal 2012 proposing a total increase in tax of $254 million, subject to interest, related to a foreign tax credit matter. The Company contested these deficiencies by filing petitions with the U.S. Tax Court. During the three months ended August 31, 2016, the Company reached a resolution with the IRS on this matter. Decisions were subsequently filed in U.S. District Tax Court stating there is no deficiency in income tax due from the Company. The Company has now resolved all U.S. federal income tax matters through fiscal 2012. T he Company’s major foreign jurisdictions, China and the Netherlands, have concluded substantially all income tax matters through calendar 2006 and fiscal 2010, respectively. Although the timing of resolution of audits is not certain, the Company evaluates all domestic and foreign audit issues in the aggregate, along with the expiration of applicable statutes of limitations, and estimates that it is reasonably possible the total gross unrecognized tax benefits could decrease by up to $168 million within the next 12 months.
