The Company's consolidated effective income tax rate may change periodically due to changes in enacted statutory tax rates, changes in tax law or policy, changes in the composition of taxable income from the countries in which it operates, the Company's ability to utilize net operating loss and tax credit carryforwards, and changes in unrecognized tax benefits. The Company’s effective income tax rate in 2021 was impacted by enacted foreign tax rate changes, change in valuation allowances for certain jurisdictions, and deferred taxes attributable to certain undistributed foreign earnings that are no longer permanently reinvested. The Company's effective income tax rate in 2020 was impacted by goodwill impairment charges, disposals and liquidations of businesses, and deferred taxes attributable to undistributed foreign earnings that are no longer permanently reinvested. The Company's effective income tax rate in 2019 was impacted by goodwill impairment charges, arbitration and claim settlements, and valuation allowance establishment on certain state net operating losses. During 2021 and 2020, the Company released its permanent reinvestment position on a portion of prior year undistributed earnings for certain foreign operations and accrued deferred taxes attributable to these earnings. Beyond these earnings we have not changed the reinvestment assertion on our undistributed earnings or other outside basis differences of our remaining foreign subsidiaries. Excluding the change in position for certain foreign operations, no additional income or withholding taxes have been provided for indefinitely reinvested undistributed foreign earnings, other than those previously taxed nor have any taxes been provided for outside basis difference inherent in these entities as these amounts continue to be indefinitely reinvested in foreign operations. We have estimated that we have book over tax basis differences of approximately $90,269,000. Due to withholding tax, basis computations, and other related tax considerations, it is not practicable to estimate any taxes to be provided on outside basis differences at this time. Topic 740, No. 5, Accounting for Global Intangible Low-Taxed Income, states that an entity can make an accounting policy election to either recognize deferred taxes for temporary basis differences expected to reverse as GILTI in future years or to provide for the tax expense related to GILTI in the year the tax is incurred as a period expense only. The Company has elected to account for GILTI in the year the tax is incurred. Deferred income taxes consisted of the following at December 31, 2021 and 2020:

An estimated $22,288,000 of the deferred tax assets will not expire, and $6,064,000 will expire over the next 20 years if not utilized by the Company.

Changes to the valuation allowance for the year ended December 31, 2021 were primarily due to anticipated expiration of certain foreign tax credits after consideration of the four sources of taxable income and losses in certain of the Company's international operations, net of releases for certain state NOLs. Changes to the valuation allowance for the year ended December 31, 2020 were primarily due to anticipated expiration of certain foreign tax credits after consideration of the four sources of taxable income and disposals and liquidations of businesses, net of losses in certain of the Company’s international operations. Changes to the valuation allowance for the year ended December 31, 2019 were primarily due to anticipated expiration of certain state NOLs after consideration of the four sources of taxable income and losses in certain of the Company’s international operations.

The Company accrues interest and, if applicable, penalties related to unrecognized tax benefits in income taxes. Total accrued interest expense at December 31, 2021, 2020, and 2019, was $119,000, $107,000, and $256,000, respectively. Included in the total unrecognized tax benefits at December 31, 2021, 2020, and 2019 were $669,000, $713,000, and $1,940,000, respectively, of tax benefits that, if recognized, would affect the effective income tax rate. The Company conducts business in a number of countries and, as a result, files U.S. federal and various state and foreign jurisdiction income tax returns. In the normal course of business, the Company is subject to examination by various taxing jurisdictions throughout the world, including Canada, the U.K., and the U.S. With few exceptions, the Company is no longer subject to income tax examinations for years before 2011. Although the outcome of tax audits is always uncertain, the Company believes that adequate amounts of tax, including interest and penalties, have been provided for any adjustments that are expected to result from those years. The Company does not expect any material reductions to unrecognized income tax benefits within the next 12 months as a result of projected resolutions of income tax uncertainties.
