As of June 29, 2019, the Company had federal, state and foreign tax net operating loss carryforwards of $5,126.6 million, $722.1 million and $603.5 million, respectively, and federal, state and foreign research and other tax credit carryforwards of $111.4 million, $51.5 million and $1.2 million, respectively. The tax net operating loss, tax credit and capital loss carryforwards will start to expire in calendar 2020 and at various other dates through 2038 if not utilized. In addition, a portion of the tax net operating loss, tax credit and capital loss carryforwards have an indefinite carryforward period. Utilization of the tax net operating losses may be subject to a substantial annual limitation due to the ownership change limitations provided by the Internal Revenue Code and similar state and foreign provisions. Loss carryforward limitations may result in the expiration or reduced utilization of a portion of the Company’s net operating losses.

Foreign withholding taxes associated with the repatriation of earnings of foreign subsidiaries have not been provided on $276.7 million of undistributed earnings for certain foreign subsidiaries. The Company intends to reinvest these earnings indefinitely outside of the United States. The Company estimates that an additional $28.0 million of foreign withholding taxes would have to be provided if these earnings were repatriated back to the U.S.

During fiscal year 2018, the U.S. Tax Cuts and Jobs Act was enacted. Income tax effects resulting from changes in tax laws were accounted for by the Company in accordance with the authoritative guidance, which required that these tax effects be recognized in the period in which the law was enacted, and the effects were recorded as a component of the provision for income taxes from continuing operations. The law had significantly changed the way the U.S. taxes corporations. The Act repealed the alternative minimum tax (“AMT”) for corporations and provided that the existing AMT credit carryforwards would be fully refunded in 2022 if not utilized. As a result, the Company recognized a benefit of $4.5 million for the year ended June 30, 2018 for the release of the valuation allowance previously maintained against the AMT credit deferred tax asset. In addition, under the Act, the Company’s fiscal 2018 net operating losses and any future net operating losses can now be carried forward indefinitely. As a result, the Company’s deferred tax liability associated with indefinite-lived intangible assets offset these indefinite-lived deferred tax assets, resulting in a benefit of $2.0 million for the year ended June 30, 2018 due to release of valuation allowance.

The Act imposed a deemed repatriation of the Company’s foreign subsidiaries’ post-1986 earnings and profits (“E&P”) which had previously been deferred from US income tax. This deemed repatriation was reported in the Company’s fiscal 2018 U.S. tax return. The Company completed the calculation of the total post-1986 foreign E&P for all foreign subsidiaries during the quarter ended December 29, 2018. The change in estimate did not materially impact the Company’s financial statements.

The Act reduced the U.S. federal corporate tax rate from 35% to 21% as of January 1, 2018. The Company remeasured its US deferred tax assets and liabilities which resulted in a net reduction of $734.9 million of our net deferred tax assets and an equal and offsetting reduction to the valuation allowance against these deferred tax assets.

Upon adoption of the new guidance on share-based payment awards in fiscal 2018, the Company had $117.7 million of net operating loss carryforwards resulting from excess tax benefit deductions. The deferred tax asset recorded for these net operating loss carryforwards was fully offset by a corresponding increase in valuation allowance, resulting in no impact to opening accumulated deficit. In addition, due to the full valuation allowance on the U.S. deferred tax assets, there was no impact to the income tax provision from excess tax benefits for the year ended June 30, 2018.

The valuation allowance increased by $23.2 million in fiscal 2019, decreased by $712.9 million in fiscal 2018, and decreased by $77.5 million in fiscal 2017. The increase during fiscal 2019 was primarily due to the net increase of deferred tax assets resulting from the inclusion of the Company’s foreign subsidiaries in the US tax return as a consequence of the the U.S. Tax Cuts and Jobs Act. The decrease during fiscal 2018 was primarily due to the revaluation of the U.S. deferred tax assets as a result of the Act. The decrease during fiscal 2017 was primarily due to the utilization of deferred tax assets and the increase in deferred tax liabilities as result of the issuance of convertible debt. The following table provides information about the activity of our deferred tax valuation allowance (in millions):

The unrecognized tax benefits relate primarily to the allocations of revenue and costs among the Company’s global operations and the validity of some U.S. tax credits. Included in the balance of unrecognized tax benefits at June 29, 2019 are $9.9 million of tax benefits that, if recognized, would impact the effective tax rate. Also included in the balance of unrecognized tax benefits at June 29, 2019 are $41.0 million of tax benefits that, if recognized, would result in adjustments to the valuation allowance.

The Company’s policy is to recognize accrued interest and penalties related to unrecognized tax benefits within the income tax provision. The amount of interest and penalties accrued as of June 29, 2019 , June 30, 2018 and July 1, 2017 was approximately $3.7 million, $1.9 million, and $1.8 million respectively. During fiscal 2019, the Company’s accrued interest and penalties increased by $1.8 million. The timing and resolution of income tax examinations is uncertain, and the amounts ultimately paid, if any, upon resolution of issues raised by the taxing authorities may differ from the amounts accrued for each year. Although we do not expect that our balance of gross unrecognized tax benefits will change materially in the next 12 months, given the uncertainty in the development of ongoing income tax examinations, we are unable to estimate the full range of possible adjustments to this balance.
