Total provision for income taxes | $ | 479 |  |  | $ | 676 |  |  | $ | 576 |
Income before income taxes is earned in the following tax jurisdictions:
| Year Ended December 31
| 2021 |  | 2020 |  | 2019
United States | $ | 1,580 |  |  | $ | 2,336 |  |  | $ | 2,252 |
Other countries | 645 |  |  | 594 |  |  | 398 |
Total income before income taxes | $ | 2,225 |  |  | $ | 2,930 |  |  | $ | 2,650 |
Deferred income tax assets and liabilities are composed of the following:
| December 31
| 2021 |  | 2020
Deferred tax assets |  |  |
Pension and other postretirement benefits | $ | 215 |  |  | $ | 239 |
Tax credits and loss carryforwards | 531 |  |  | 477 |
Lease liability | 116 |  |  | 117 |
Prepaid royalties | 117 |  |  | 1 |
Other | 355 |  |  | 464 |
| 1,334 |  |  | 1,298 |
Valuation allowances | (279) |  |  | (272) |
Total deferred tax assets | 1,055 |  |  | 1,026 |
Deferred tax liabilities |  |  |
Property, plant and equipment, net | 921 |  |  | 900 |
Investments in subsidiaries | 105 |  |  | 111 |
Intangible assets | 156 |  |  | 159 |
Lease asset | 114 |  |  | 117 |
Other | 228 |  |  | 200 |
Total deferred tax liabilities | 1,524 |  |  | 1,487 |
Net deferred tax assets (liabilities) | $ | (469) |  |  | $ | (461) |
Valuation allowances at the end of 2021 primarily relate to tax credits, capital loss carryforwards, and income tax loss carryforwards of $1,286. If these items are not utilized against taxable income, $682 of the income tax loss carryforwards will expire from 2022 through 2041. The remaining $604 has no expiration date. Realization of income tax loss carryforwards is dependent on generating sufficient taxable income prior to expiration of these carryforwards. Although realization is not assured, we believe it is more likely than not that all of the deferred tax assets, net of applicable valuation allowances, will be realized. The amount of the deferred tax assets considered realizable could be reduced or increased due to changes in the tax environment or if estimates of future taxable income change during the carryforward period. Presented below is a reconciliation of the income tax provision computed at the U.S. federal statutory tax rate to the actual effective tax rate:
| Year Ended December 31
| 2021 |  | 2020 |  | 2019
U.S. statutory rate applied to income before income taxes | 21.0 | % |  | 21.0 | % |  | 21.0 | %
State income taxes, net of federal tax benefit | 1.2 |  |  | 2.3 |  |  | 2.5 |
Routine tax incentives | (5.8) |  |  | (4.3) |  |  | (3.5) |
Nondeductible expenses | 1.5 |  |  | 0.8 |  |  | 0.4 |
Net tax cost on foreign income | 2.4 |  |  | 2.7 |  |  | 1.5 |
Valuation allowance | 2.4 |  |  | 0.7 |  |  | 1.0 |
Nonrecurring capital loss | — |  |  | — |  |  | (1.8) |
Other - net(a) | (1.2) |  |  | (0.1) |  |  | 0.6 |
Effective income tax rate | 21.5 | % |  | 23.1 | % |  | 21.7 | %
(a) Other - net is composed of numerous items, none of which is greater than 1.05 percent of income before income taxes. In December 2019, we generated a nonrecurring capital loss from a legal entity restructuring and recorded a net benefit of $47. As of December 31, 2021, we have accumulated undistributed earnings generated by our foreign subsidiaries of approximately $7.8 billion. Earnings of $4.4 billion were previously subject to tax, primarily due to the one-time transition tax on foreign earnings required by the 2017 U.S. Tax Cuts and Jobs Act. Any additional taxes due with respect to such previously-taxed earnings, if repatriated, would generally be limited to foreign and U.S. state income taxes. Deferred taxes have been recorded on $0.8 billion of earnings, most of which were previously taxed for U.S. federal income tax purposes, of foreign consolidated subsidiaries expected to be repatriated. We do not intend to distribute the remaining $3.6 billion of previously-taxed foreign earnings and therefore have not recorded deferred taxes for foreign and U.S. state income taxes on such earnings. We consider any excess of the amount for financial reporting over the tax basis in our foreign subsidiaries to be indefinitely reinvested. The determination of deferred tax liabilities on the amount of financial reporting over tax basis or the $3.6 billion of previously taxed foreign earnings is not practicable. Presented below is a reconciliation of the beginning and ending amounts of unrecognized income tax benefits:
| 2021 |  | 2020 |  | 2019
Balance at January 1 | $ | 497 |  |  | $ | 383 |  |  | $ | 298 |
Gross increases for tax positions of prior years | 62 |  |  | 144 |  |  | 36 |
Gross decreases for tax positions of prior years | (37) |  |  | (34) |  |  | (13) |
Gross increases for tax positions of the current year | 42 |  |  | 36 |  |  | 87 |
Settlements | (39) |  |  | (22) |  |  | (13) |
Other | (19) |  |  | (10) |  |  | (12) |
Balance at December 31 | $ | 506 |  |  | $ | 497 |  |  | $ | 383 |
Of the amounts recorded as unrecognized tax benefits at December 31, 2021, $432 would reduce our effective tax rate if recognized. We recognize accrued interest and penalties related to unrecognized tax benefits in income tax expense. During each of the three years ended December 31, 2021, the net impact of interest and penalties was not significant. Total accrued penalties and net accrued interest was $24 and $20 at December 31, 2021 and 2020, respectively. It is reasonably possible that a number of uncertainties could be resolved within the next 12 months. The aggregate resolution of the uncertainties could be up to $210, whil e none of the uncertainties is individually significant. Resolution of these matters is not expected to have a material effect on our financial condition, results of operations or liquidity. As of December 31, 2021, the following tax years remain subject to examination for the major jurisdictions where we conduct business:
Jurisdiction | Years
United States | 2016 | to | 2021
United Kingdom | 2017 | to | 2021
Brazil | 2015 | to | 2021
China | 2009 | to | 2021
South Korea | 2019 | to | 2021
Our U.S. federal income tax returns have been audited through 2015 and U.S. federal income tax amended returns are subject to audit for 2013-2015. State income tax returns are generally subject to examination for a period of 3 to 5 years after filing of the respective return. The state effect of any changes to filed federal positions remains subject to examination by various states for a period of up to two years after formal notification to the states. We have various state income tax return positions in the process of examination, administrative appeals or litigation. The Brazilian tax authority, Secretaria da Receita Federal do Brasil ("RFB"), concluded an audit for the taxable periods from 2008-2013. This audit included a review of our determinations of amortization of certain goodwill arising from prior acquisitions in Brazil, and the RFB has proposed adjustments that effectively eliminate the goodwill amortization benefits related to these transactions. Administrative appeals have been exhausted, and the dispute is moving into the judicial phase. The amount of the proposed tax adjustments and penalties is approxima tely $80 as of Decembe r 31, 2021 (translated at the December 31, 2021 currency exchange rate). The amount ultimately in dispute will be significantly greater because of interest. We believe we have meritorious defenses and intend to vigorously defend against these proposed adjustments; however, it is expected to take a number of years to reach resolution of this matter. The U.S. Internal Revenue Service ("IRS") is currently auditing our federal tax return for the taxable years ended December 31, 2017 and 2018. As part of this tax audit, the IRS is reviewing our one-time transition tax on certain undistributed earnings of foreign subsidiaries. The IRS has proposed an adjustment that would increase the amount of the transition tax owed by us. We believe we have adequate reserves and meritorious defenses and intend to vigorously defend against the proposed adjustment; however, it is expected to take a number of years to reach resolution of this matter.
