(2) The impact of global income from operations in jurisdictions with lower statutory tax rates than the U.S., including Poland, which has a statutory income tax rate of 19.0%.
(3) Permanent tax benefit related to a worthless stock deduction from the reorganization and exit of the Company's steel trading business headquartered in the United Kingdom.

Beginning in fiscal 2020, the Company plans to repatriate the current and future earnings from the Europe segment and recorded an immaterial amount of tax expense related to such future distributions. The Company considers all undistributed earnings of its non-U.S. subsidiaries prior to August 31, 2019 to be indefinitely reinvested and has not recorded deferred tax liabilities on such earnings.

The income tax effects of significant temporary differences giving rise to deferred tax assets and liabilities were as follows:
 Year Ended August 31,
(in thousands)20202019
Deferred tax assets:  
Net operating losses and credits$283,416 $295,241

Other(2,420)(1,182)
Total deferred tax liabilities(216,216)(169,883)
Net deferred tax liabilities$(119,051)$(71,411)

Net operating losses giving rise to deferred tax assets consist of $447.5 million of state net operating losses that expire during the tax years ending from 2021 to 2040 and foreign net operating losses of $816.9 million that expire in varying amounts beginning in 2021 (with certain amounts having indefinite carryforward periods). These assets will be reduced as income tax expense is recognized in future periods.

The Company maintains a valuation allowance to reduce certain deferred tax assets to amounts that are more likely than not to be realized. The Company's valuation allowances primarily relate to net operating loss carryforwards in certain state and foreign jurisdictions and certain credit carryforwards for which utilization is uncertain.

A reconciliation of the beginning and ending amounts of unrecognized income tax benefits is as follows:
Year Ended August 31,
(in thousands)202020192018
Balance at September 1,$8,652 $3,121 $9,283 
Change for tax positions of prior years— 5,531 3,121 
Reductions due to settlements with taxing authorities— — (8,028)
Reductions due to lapse of statute of limitations— — (1,255)
Balance at August 31, (1)
$8,652 $8,652 $3,121 
__________________________________
(1)The full balance of unrecognized income tax benefits in each year, if recognized, would have impacted the Company’s effective income tax rate at the end of each respective year.

At August 31, 2020 and 2019, accrued interest and penalties related to uncertain tax positions was not material.
During the twelve months ending August 31, 2021, we anticipate that the statute of limitations pertaining to positions of the Company in prior year income tax returns may lapse. As a result, it is reasonably possible that the amount of unrecognized tax benefits may decrease by $3.1 million.

The Company files income tax returns in the U.S. and multiple foreign jurisdictions with varying statutes of limitations. In the normal course of business, the Company and its subsidiaries are subject to examination by various taxing authorities. The Company is currently under examination with certain state revenue authorities for fiscal years 2015 through 2018. The following is a summary of all tax years that are open to examination.

U.S. Federal — 2016 and forward
U.S. States — 2015 and forward
Foreign — 2013 and forward
