Deferred taxes associated with U.S. entities consist of net deferred tax assets of $33.3 million as of December 31, 2024 and net deferred tax liabilities of $20.5 million as of December 31, 2023. Deferred taxes associated with non-U.S. entities consist of net deferred tax assets of $53.1 million and $46.9 million as of December 31, 2024 and 2023, respectively. During 2024,

the Company’s valuation allowance increased by $55.1 million primarily due to establishing a valuation allowance against a portion of the Company’s U.S. interest carryforwards.

The Company has determined that unremitted foreign earnings are not considered indefinitely reinvested to the extent foreign earnings can be distributed without a significant tax cost. As such, the Company has recorded foreign withholding tax liabilities related to the future repatriation of such earnings. The Company continues to indefinitely reinvest all other outside basis differences to the extent reversal would incur a significant tax liability. It is not practicable for the Company to calculate the unrecognized deferred tax liability related to such incremental tax costs on those outside basis differences. The deferred tax liability for unremitted foreign earnings was $16.7 million as of December 31, 2024, which represents our estimate of the net tax cost associated with the deemed remittance of certain foreign earnings that are not considered to be permanently reinvested.

Current tax law in the United States imposes tax on U.S. stockholders for global intangible low-taxed income (“GILTI”) earned by certain foreign subsidiaries. The Company is required to make an accounting policy election of either: (1) treating taxes due on future amounts included in the U.S. taxable income related to GILTI as a current period tax expense when incurred (“the period cost method”); or (2) factoring such amounts into the Company’s measurement of its deferred tax expense (the “deferred method”). In 2018, the Company elected the period cost method for its accounting for GILTI.

The effective income tax rate for the years ended December 31 varies from the U.S. statutory federal income tax rate as follows:

	Percentage of Pretax Income
	2024		2023		2022
Statutory federal income tax rate	21.0	%	21.0	%	21.0	%
Increase (decrease) in tax rate resulting from:
State income taxes (net of federal income tax benefit)	3.6		21.2		0.3
Impact of foreign operations	1.5		43.9		(5.0)
Foreign-Derived Intangible Income (“FDII”)	—		—		(0.7)
Subpart F and GILTI, net of foreign tax credits	(2.0)		(51.1)		6.7

The Company realized tax benefits of $1.6 million, $3.6 million, and $7.2 million in 2024, 2023 and 2022, respectively, for tax deductions attributable to stock-based compensation, of which, the excess tax benefit over the amount recorded for financial reporting purposes was $0.1 million, $1.5 million and $4.6 million in 2024, 2023 and 2022, respectively. As required by ASU 2016-09, Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting (“ASU 2016-09”), the excess tax benefits for the years ended December 31, 2024, 2023 and 2022 have been included in the provision for income taxes.

The Company evaluates the future realizability of tax credits and loss carryforwards considering the anticipated future earnings of the Company’s subsidiaries as well as tax planning strategies in the associated jurisdictions. Included in deferred income taxes as of December 31, 2024 are tax benefits for U.S. and non-U.S. net operating loss carryforwards totaling $30.7 million ($27.6 million of which the Company does not expect to realize and has corresponding valuation allowances). Certain of the losses can be carried forward indefinitely and others can be carried forward to various dates from 2025 through 2044.

As of December 31, 2024, gross unrecognized tax benefits totaled $3.6 million ($5.3 million, including $1.7 million associated with potential interest and penalties). As of December 31, 2023, gross unrecognized tax benefits totaled $5.1 million ($7.3 million, including $2.2 million associated with potential interest and penalties). The Company recognized $(0.5) million, $(0.4) million and $0.6 million in potential interest and penalties associated with uncertain tax positions during 2024, 2023 and 2022, respectively. To the extent unrecognized tax benefits (including interest and penalties) are recognized with respect to uncertain tax positions, the tax expense in future periods would be reduced by $5.3 million based upon the tax positions as of December 31, 2024. The Company recognized interest and penalties related to unrecognized tax benefits within income taxes in the accompanying Consolidated Statements of Operations. Unrecognized tax benefits and associated accrued interest and penalties are included in taxes, income and other accrued expenses as detailed in Note 10.

A reconciliation of the beginning and ending amount of unrecognized tax benefits, excluding amounts accrued for potential interest and penalties, is as follows ($ in millions):

	2024		2023		2022
Unrecognized tax benefits, beginning of year	$	5.1	$	6.6	$	5.7
Additions based on tax positions related to the current year	—		0.3		0.3
Additions for tax positions of prior years	—		0.3		4.2
Reductions for tax positions of prior years	—		(0.2)		—
Lapse of statute of limitations	(1.4)		(1.3)		(2.3)
Settlements	—		(0.4)		(1.1)
Effect of foreign currency translation	(0.1)		(0.2)		(0.2)
Unrecognized tax benefits, end of year	$	3.6	$	5.1	$	6.6

The Company is routinely examined by various domestic and international taxing authorities and operations in certain U.S. states and foreign jurisdictions remain subject to routine examination for tax years beginning with 2009.

The Company estimates that it is reasonably possible that the amount of unrecognized tax benefits may be reduced by approximately $1.9 million within twelve months through resolution of worldwide tax matters, payments of tax audit settlements and/or statute of limitations expirations.

The Company operates in various non-U.S. tax jurisdictions where “tax holiday” income tax incentives have been granted for a specific period. These tax benefits are not material to the Company’s financial statements.
