Income Tax Disclosure [Abstract] |
Taxes | Taxes Effective Tax Rate The Company estimates its annual effective tax rate at the end of each fiscal quarter. The effective tax rate takes into account the Company's estimations of annual pre-tax income, the geographic mix of pre-tax income and interpretations of tax laws and possible outcomes of audits. The following table presents the provision (benefit) for income taxes and the effective tax rates:
| Three Months Ended July 31, |  | Nine Months Ended July 31,
| 2016 |  | 2015 |  | 2016 |  | 2015
| (in thousands)
Income before income taxes | $ | 85,231 |  |  | $ | 65,193 |  |  | $ | 246,796 |  |  | $ | 225,692 |
Provision (benefit) for income taxes | $ | 20,513 |  |  | $ | 9,806 |  |  | $ | 52,667 |  |  | $ | 49,520 |
Effective tax rate | 24.1 | % |  | 15.0 | % |  | 21.3 | % |  | 21.9 | %
The Company’s effective tax rate for the three and nine months ended July 31, 2016 is lower than the statutory federal income tax rate of 35% primarily due to lower taxes on certain earnings considered as indefinitely reinvested in foreign operations and U.S. federal and California research tax credits, partially offset by state taxes and the tax effect of non-deductible stock compensation and the integration of acquired technologies. The integration of acquired technologies represents the income tax effect resulting from the transfer of certain intangible assets among company-controlled entities. The Company's effective tax rate increased in the three months ended July 31, 2016, as compared to the same period in fiscal 2015, primarily due to an increase in the valuation allowance on deferred tax assets as a result of changes in the utilization of state credits. The effective tax rate for the three months ended July 31, 2015 was lower due to the tax benefits of final settlement with the Examination Division of the IRS. The effective tax rate decreased in the nine months ended July 31, 2016, as compared to the same period in fiscal 2015, primarily due to the permanent reinstatement of the U.S. federal research tax credit and an amendment to its intercompany cost-sharing arrangements to exclude stock-based compensation expense, partially offset by an increase in the valuation allowance on deferred tax assets. On December 18, 2015, the president signed into law the Protecting Americans from Tax Hikes Act of 2015 which permanently reinstated the research tax credit retroactive to January 1, 2015. As a result of the new legislation, the Company recognized a benefit in the first quarter of 2016 related to ten months of fiscal 2015 and two months of fiscal 2016 as well as a benefit to the annual effective tax rate for ten months of fiscal 2016. On December 19, 2014, the president signed into law the Tax Increase Prevention Act of 2014 which reinstated the research tax credit retroactive to January 1, 2014 and extended the credit through December 31, 2014. As a result of the new legislation, the Company recognized a benefit in the first quarter of fiscal 2015 related to ten months of fiscal 2014 as well as a benefit to the annual effective tax rate for two months of fiscal 2015. On July 27, 2015, the Tax Court issued an opinion (Altera Corp. et al. v. Commissioner) regarding the treatment of stock-based compensation expense in intercompany cost-sharing arrangements. The U.S. Treasury has not withdrawn the requirement to include stock-based compensation from its regulations and the IRS has initiated an appeal of the Tax Court's opinion. As the final resolution with respect to historical cost-sharing of stock-based compensation, and the potential favorable benefits to the Company, is unclear, the Company is recording no impact at this time and will continue to monitor developments related to this opinion and the potential impact of those developments on the Company's prior fiscal years. Effective February 1, 2016, the Company amended its cost-sharing arrangement to exclude stock-based compensation expense on a prospective basis and has reflected the corresponding benefits in its effective annual tax rate. The Company’s total gross unrecognized tax benefits as of July 31, 2016 are $111.5 million exclusive of interest and penalties. If the total gross unrecognized tax benefits as of July 31, 2016 were recognized in the future, approximately $108.6 million would decrease the effective tax rate. The timing of the resolution of income tax examinations is highly uncertain as well as the amounts and timing of various tax payments that are part of the settlement process. This could cause large fluctuations in the balance sheet classification of current and non-current assets and liabilities. The Company believes that in the coming 12 months, it is reasonably possible that either certain audits will conclude or the statute of limitations on certain state and foreign income and withholding taxes will expire, or both. Given the uncertainty as to ultimate settlement terms, the timing of payment and the impact of such settlements on other uncertain tax positions, the range of the estimated potential decrease in underlying unrecognized tax benefits is between $0 and $20 million. During the first quarter of fiscal 2016, the Company early adopted Accounting Standards Update (ASU) 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes (ASU 2015-17) on a retrospective basis. As required by ASU 2015-17, all deferred tax assets and liabilities are classified as non-current in the Company's unaudited condensed consolidated balance sheets, which is a change from the Company's prior period presentations whereby certain of its deferred tax assets were classified as current and the remainder were classified as non-current. Upon adoption of ASU 2015-17, current deferred tax assets of $95.0 million in the Company's October 31, 2015 consolidated balance sheet were reclassified as non-current. IRS Examinations In the third quarter of fiscal 2015, the Company reached final settlement with the Examination Division of the IRS on the integration of acquired technologies for fiscal 2015 and research tax credit for fiscal 2014 that resulted in $7.0 million and $3.2 million in tax benefits, respectively. State Examinations In the first quarter of fiscal 2016, the Company reached final settlement with the California Franchise Tax Board for fiscal 2011, 2010 and 2009. As a result of the settlement, the Company reduced its deferred tax assets by $4.9 million, recognized $10.3 million in unrecognized tax benefits, and increased its valuation allowance by $5.4 million. Non-U.S. Examinations In the third quarter of fiscal 2016, the Company reached final settlement with the Taiwan tax authorities for fiscal 2011, with regard to certain transfer pricing issues. As a result of the settlement, the Company paid $0.3 million of tax and recognized $0.7 million in unrecognized tax benefits. In the second quarter of fiscal 2016, the Company agreed to settle certain transfer pricing issues with the Indian tax authorities for fiscal years 2010 to 2015. As a result of the settlement, the Company recognized income tax expense, net of foreign tax credits, of $2.4 million. In the first quarter of fiscal 2015, the Company reached final settlement with the Taiwan tax authorities for fiscal 2012, with regard to certain transfer pricing issues. As a result of the settlement, the Company recognized approximately $1.1 million in unrecognized tax benefits.
