Valuation Allowances
As of December 31, 2021, the Company had $16.6 million deferred tax assets related to net operating loss (“NOL”) carryforwards for U.S. federal tax purposes. The Company believes that these attributes will be fully utilized and has therefore not established a valuation allowance. As of December 31, 2021, the Company had foreign tax credit carryforwards for U.S. federal tax purposes of $18.0 million, which begin to expire in 2025. The Company believes it is likely the credits will expire unused and therefore has established a full valuation allowance. As of December 31, 2021, the Company also had a deferred tax asset for state carryforward attributes of approximately $15.0 million (expiring 2023 through 2040), comprised of NOL, credit, and capital loss carryforwards. The Company believes that it is likely that the capital losses and certain of the state NOLs will expire unused and therefore has established a valuation allowance of approximately $7.5 million against the deferred tax assets associated with these attributes. The Company also has deferred tax assets related to carryforwards in foreign jurisdictions of approximately $6.7 million, comprised of NOL and interest expense carryforwards, which begin to expire in 2022. The Company believes that it is likely that certain foreign NOL carryforwards will expire unused and therefore has established a valuation allowance of approximately $4.3 million.
Undistributed Foreign Earnings
The Company has determined that an amount approximately equal to foreign cash balances and other certain assets is not permanently reinvested for withholding tax purposes, which results in an accrual of $10.4 million. It is not practicable to calculate deferred tax balances on other basis differences.
Unrecognized Tax Benefits
Unrecognized tax benefits reflect the difference between the tax benefits of positions taken or expected to be taken on income tax returns and the tax benefits that meet the criteria for current recognition in the financial statements. The Company periodically assesses its unrecognized tax benefits. 
A summary of the movement in gross unrecognized tax benefits (before estimated interest and penalties) follows:
(in millions)202120202019
Balance as of January 1$24.3 $35.7 $27.1 
Additions based on tax positions related to current year1.4 0.4 0.3 
Reductions due to statute of limitations(9.1)(10.8)(4.8)
Adjustments related to acquired uncertain tax positions— (0.8)11.6 
Adjustments for tax positions of prior years(0.2)— 1.8 
Reductions due to settlements— — (0.1)
Adjustments due to foreign exchange rates(0.2)(0.2)(0.2)
Balance as of December 31$16.2 $24.3 $35.7 
If the unrecognized tax benefits as of December 31, 2021, were to be recognized, approximately $19.1 million would impact the Company’s effective tax rate. The amount impacting the Company’s effective rate is calculated by adding accrued interest and penalties to the gross unrecognized tax benefit excluding positions related to discontinued operations and subtracting the tax benefit associated with state taxes and interest.
The Company classifies and reports interest and penalties associated with unrecognized tax benefits as a component of the income tax provision on the Consolidated Statements of Income and as a long-term liability on the Consolidated Balance Sheets. The total amount of such interest and penalties accrued, but excluded from the table above, at the years ending 2021, 2020 and 2019 were $7.3 million, $7.9 million and $8.9 million, respectively.
The Company is subject to U.S. federal income tax as well as income tax in multiple state and foreign jurisdictions. The Company participates in the IRS compliance assurance program and is currently up to date.
Generally, state income tax returns are subject to examination for a period of three years to five years after filing. Substantially all material state tax matters have been concluded for tax years through 2015. Various state income tax returns for subsequent years are in the process of examination. At this stage the outcome is uncertain; however, the Company believes that contingencies have been adequately provided for. Statutes of limitation vary among the foreign jurisdictions in which the Company operates. Substantially all foreign tax matters have been concluded for tax years through 2009. The Company believes that foreign tax contingencies associated with income tax examinations underway or open tax years have been provided for adequately.
Based on the outcome of certain examinations or as a result of the expiration of statutes of limitations for certain jurisdictions, the Company believes that within the next 12 months it is reasonably possible that previously unrecognized tax benefits could decrease by approximately $2.0 million to $4.0 million. These previously unrecognized tax benefits relate to a variety of tax issues including tax matters relating to prior acquisitions and various state matters.
