(1)Tax rates in foreign jurisdictions were generally lower than the U.S. federal statutory rate through December 31, 2020. This results in an adverse impact to the provision (benefit) for income taxes in this rate reconciliation for the years ended December 31, 2020, 2019 and 2018 prior to the impact of valuation allowances, due to the net pretax losses from continuing operations in certain foreign jurisdictions with lower tax rates.
(2)During the year ended December 31, 2019, we updated our net operating losses to remove deferred tax assets that could never be utilized due to IRC Section 382 limitations. The amount of State income taxes, net of federal benefits, and state tax credits, Change in valuation allowances and Non-deductible or non-taxable items for the year ended December 31, 2018 have been updated from $2.0 million, $3.8 million and $7.3 million previously reported to reflect that change.
