(1)State taxes in Virginia, Maryland, and the District of Columbia make up the majority (greater than 50 percent) of the tax effect in this category.

(2)The 2025 provision for income tax includes a benefit recognized in the first fiscal quarter of 2025 from tax planning implemented in connection with the “transitional rules” governing unrealized foreign exchange gains and losses derived from translation of the operations, assets and liabilities of non-U.S. qualified subsidiaries provided by recently finalized U.S. federal tax regulations under IRC 987. The regulations under IRC 987 are effective for the Company for tax years beginning after December 31, 2024, and require computation of a pre-transition foreign currency gain or loss to be included in the determination of future taxable income or loss and an analysis of the various elections available to taxpayers. Based on the Company’s current analysis of the regulations and the available election to amortize its pre-2025 cumulative unrealized foreign exchange gains and losses impacting U.S. taxation of foreign earnings under Subpart F of the Internal Revenue Code, the Company recognized a non-cash deferred income tax benefit of $4.5 million related to its election to amortize its pre-transition foreign currency losses against taxable income over ten years.

(3)During 2023, the Company restructured the ownership of its Canadian entities for tax purposes, resulting in a 3.8% decrease in the Company’s effective income tax rate for the year ended December 31, 2023.

(4)During 2023, the Company liquidated one of its U.K. subsidiaries as part of the wind-down of its commercial marketing business, resulting in a reduction in the Company’s effective income tax rate of 5.1% for the year ended December 31, 2023.
