The Company continues to intend to reinvest certain of its foreign earnings indefinitely. Accordingly, no U.S. income taxes have been provided for approximately $5.1 billion of unremitted earnings of international subsidiaries. As of October 29, 2016, the amount of unrecognized deferred tax liability on these earnings was $1.4 billion.

The significant components of the Company’s deferred tax assets and liabilities for the fiscal years ended October 29, 2016 and October 31, 2015 are as follows:

The valuation allowances of $67.1 million and $52.7 million at October 29, 2016 and October 31, 2015, respectively, are valuation allowances primarily for the Company’s state credit carryover. The Company believes that it is more-likely-than-not that these credit carryovers will not be realized and as a result has recorded a full valuation allowance as of October 29, 2016. The state credit carryover of $67.9 million will begin to expire in 2016.

As of October 29, 2016, the Company has foreign tax credit carryforwards of $0.7 million to offset future passive income. If not used, these carryforwards will expire between 2019 and 2023.

The Company has provided for potential tax liabilities due in the various jurisdictions in which the Company operates. Judgment is required in determining the worldwide income tax expense provision. In the ordinary course of global business, there are many transactions and calculations where the ultimate tax outcome is uncertain. Some of these uncertainties arise as a consequence of cost reimbursement arrangements among related entities. Although the Company believes its estimates are reasonable, no assurance can be given that the final tax outcome of these matters will not be different than that which is reflected in the historical income tax provisions and accruals. Such differences could have a material impact on the Company’s income tax provision and operating results in the period in which such determination is made.

As of October 29, 2016 and October 31, 2015, the Company had a liability of $75.6 million and $75.3 million, respectively, for unrealized tax benefits, all of which, if settled in the Company’s favor, would lower the Company’s effective tax rate in the period recorded. As of October 29, 2016 and October 31, 2015, the Company had a liability of approximately $20.1 million and $16.1 million, respectively, for interest and penalties. The Company includes interest and penalties related to unrecognized tax benefits within the provision for taxes in the consolidated statements of income. The total liability as of October 29, 2016 and October 31, 2015 of $81.7 million and $81.0 million, respectively, for uncertain tax positions is classified as non-current, and is included in other non-current liabilities, because the Company believes that the ultimate payment or settlement of these liabilities may not occur within the next twelve months. The consolidated statements of income for fiscal year 2016, fiscal 2015 and fiscal 2014 include $4.0 million, $4.1 million and $1.9 million, respectively, of interest and penalties related to these uncertain tax positions. Over the next fiscal year, the Company anticipates the liability to be reduced by $1.6 million for the possible expiration of an income tax statute of limitations.

The following table summarizes the changes in the total amounts of unrealized tax benefits for fiscal 2014 through fiscal 2016:

The Company has filed a petition with the U.S. Tax Court for one open matter for fiscal years 2006 and 2007 that pertains to Section 965 of the Internal Revenue Code related to the beneficial tax treatment of dividends paid from foreign owned companies under The American Jobs Creation Act. The potential liability for this adjustment is $36.5 million. On September 18, 2013, in a matter not involving the Company, the U.S. Tax Court held that accounts receivable created under Rev. Proc. 99-32 may constitute indebtedness for purposes of Section 965 (b)(3) of the Internal Revenue Code and that the IRS was not precluded from reducing the beneficial dividend received deduction because of the increase in related-party indebtedness (BMC Software Inc. v Commissioner, 141 T.C. No. 5 2013). After analyzing the Tax Court’s decision, the Company has determined that its tax position with respect to the Section 965(b)(3) no longer meets the more likely than not standard of recognition for accounting purposes. Accordingly, the Company recorded a $36.5 million reserve for this matter in the fourth quarter of 2013.
