As of December 31, 2021, deferred U.S. income taxes have not been provided on the undistributed earnings of the Company’s foreign subsidiaries since these earnings will not be taxable upon repatriation to the United States. These earnings will be primarily treated as previously taxed income from either the one-time transition tax or global intangible low-taxed income (“GILTI”) provision, or they will be offset with a 100% dividend received deduction. However, the Company continues to provide a deferred tax liability for foreign income and withholding tax that will be incurred with respect to the undistributed foreign earnings that are not indefinitely reinvested. The deferred tax assets and deferred tax liabilities and related valuation allowance were comprised of the following as of December 31, 2021 and 2020:

The Company has Net Operating Loss (“NOL”) carryforwards as follows:
Jurisdiction |  | Amount as of December 31, 2021 |  |  | Years of Expiration
U.S. state income tax |  | $ | 67,795 |  |  | 2022-2041
Foreign |  | $ | 199,153 |  |  | Never
We have NOL carryforwards in various states associated with the benefits of the state dividends received reduction and foreign royalty exclusion. The state NOL carryforwards generally expire at various dates from 2022 to 2041. We have concluded that there is not sufficient evidence these NOL carryforwards will be utilized, and thus have not recognized the benefit of these NOL carryforwards. At December 31, 2021, certain non-U.S. subsidiaries had NOL carryforwards totaling $199,153 which have no expiration date. The Company is subject to taxation in the United States and various state and foreign jurisdictions. As of December 31, 2021, the Company was no longer subject to U.S. Federal examinations by tax authorities for tax years before 2017 and was no longer subject to foreign examinations by tax authorities for tax years before 2014. The Company currently benefits from tax holidays in various non-U.S. jurisdictions with expiration dates from 2024 – 2025. The amount of corporate income tax savings realized by the Company as a result of the tax holidays during the current and prior years was immaterial as a result of operating losses previously generated. At December 31, 2021, 2020 and 2019, the Company had total unrecognized tax benefits of $5,665, $4,967 and $3,795, respectively, all of which, if recognized, would affect the effective income tax rates. The reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows:
|  | Year Ended December 31, |
|  | 2021 |  |  | 2020 |  |  | 2019 |
Balance at beginning of year |  | $ | 4,967 |  |  | $ | 3,795 |  |  | $ | 2,819 |
Additions based on tax position related to current year |  |  | 1,105 |  |  |  | 1,489 |  |  |  | 661 |
Additions based on tax position related to prior year |  |  | 160 |  |  |  | 179 |  |  |  | 352 |
Reductions from settlements and statute of limitation expiration |  |  | (312 | ) |  |  | (650 | ) |  |  | — |
Effect of foreign currency translation |  |  | (255 | ) |  |  | 154 |  |  |  | (37 | )
Balance at end of year |  | $ | 5,665 |  |  | $ | 4,967 |  |  | $ | 3,795 |
The Company classifies income tax-related penalties and net interest as income tax expense. In the years ended December 31, 2021, 2020 and 2019, income tax related interest and penalties were not material. It is reasonably possible that audit settlements, the conclusions of current examinations or the expiration of the statute of limitations in several jurisdictions could impact the Company’s unrecognized tax benefits.
