The effective tax rate of 26.1% differs from the U.S. statutory rate of 21.0% in the three-month period ended January 30, 2022, primarily due to the non-recognition of the tax benefit of losses that, in certain jurisdictions, have been offset by valuation allowances, non-U.S. pre-tax income being taxed at higher statutory rates in the non-U.S. jurisdictions, and the establishment of uncertain tax positions in non-U.S. jurisdiction.

The effective tax rate of 23.6% in the three-month period ended January 31, 2021, differs from the U.S. statutory rate of 21.0% primarily due to the non-recognition of the tax benefit of losses that, in certain jurisdictions, have been offset by valuation allowances and non-U.S. pre-tax income being taxed at higher statutory rates in the non-U.S. jurisdictions that were partially offset by the benefits of investment credits in a foreign jurisdiction.

Although the timing of the expirations of statutes of limitations may be uncertain, as they can be dependent upon the settlement of tax audits, we believe that the amount of uncertain tax positions (including interest and penalties, and net of tax benefits) that may be resolved over the next twelve months is immaterial. Resolution of these uncertain tax positions may result from either or both the lapses of statutes of limitations and tax settlements. We are no longer subject to tax authority examinations in the U.S. and major foreign or state jurisdictions for years prior to fiscal year 2016. The table below presents information on our unrecognized tax benefits as of the balance sheet dates.
