Basis of Presentation and Recent Accounting Pronouncements | Note 2 — Basis of Presentation and Recent Accounting Pronouncements Basis of Presentation The accompanying unaudited quarterly condensed consolidated financial statements of WTW and our subsidiaries are presented in accordance with the rules and regulations of the SEC for quarterly reports on Form 10-Q and therefore certain footnote disclosures have been condensed or omitted from these financial statements as they are not required for interim reporting under U.S. GAAP. In the opinion of management, these condensed consolidated financial statements reflect all adjustments, consisting of normal recurring adjustments, which are necessary for a fair presentation of the condensed consolidated financial statements and results for the interim periods. Certain prior-period amounts have been reclassified to conform to the current-period presentation. All intercompany accounts and transactions have been eliminated in consolidation. The condensed consolidated financial statements should be read together with the Company’s Annual Report on Form 10-K, filed with the SEC on February 25, 2025, and may be accessed via EDGAR on the SEC’s web site at www.sec.gov. The results of operations for the three and nine months ended September 30, 2025 are not necessarily indicative of the results that can be expected for the entire year. The Company experiences seasonal fluctuations of its revenue. Revenue is typically higher during the Company’s first and fourth quarters due primarily to the timing of broking-related activities. The results reflect certain estimates and assumptions made by management, including those estimates used in calculating acquisition consideration and fair value of tangible and intangible assets and acquisition-related liabilities, professional liability claims, estimated bonuses, valuation of billed and unbilled receivables, and anticipated tax liabilities that affect the amounts reported in the condensed consolidated financial statements and related notes. Recent Accounting Pronouncements Not Yet Adopted In March 2024, the SEC adopted final rules on the enhancement and standardization of climate-related disclosures for investors (the ‘SEC Climate Rules’). The SEC Climate Rules would require disclosure of certain climate-related information, including in the notes to the Company’s financial statements, in registration statements and annual reports on Form 10-K. Following a number of legal challenges, the SEC voluntarily stayed the SEC Climate Rules pending the completion of judicial review of such consolidated petitions to avoid regulatory uncertainty for companies subject to the SEC Climate Rules. The Company is monitoring the outcome of the litigation. In November 2024, the FASB issued ASU No. 2024-03, Disaggregation of Income Statement Expense, which is intended to provide transparency about the components of expenses included in the income statement. This ASU requires public companies to disclose additional information about certain expenses in the notes to the financial statements on a quarterly and annual basis, including purchases of inventory, employee compensation, depreciation, intangible asset amortization and depletion for each income statement line item that contains those expenses. The ASU requires a new tabular disclosure format that centralizes expense information and additional qualitative disclosure. The guidance does not change the existing income statement presentation. The annual requirements for this ASU become effective with the Company's Annual Report on Form 10-K for the year ended December 31, 2027, and for its interim periods beginning on January 1, 2028. Early adoption is permitted. The guidance is to be applied prospectively, with the option for retrospective application. The Company currently does not plan to early-adopt this ASU and is assessing the expected impact on its condensed consolidated financial statements. In July 2025, the FASB issued ASU 2025-05, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets, which is intended to improve guidance on the measurement of credit losses for accounts receivable and contract assets. This ASU provides an optional practical expedient to assume that current conditions as of the balance sheet date do not change for the remaining life of the assets. The requirements for this ASU become effective for the Company on January 1, 2026. Early adoption is permitted and the guidance is applied prospectively to estimates of expected credit losses on asset balances prepared after the date of adoption. The Company does not intend to early-adopt this ASU and does not expect the ASU to have a material impact on its condensed consolidated financial statements. In September 2025, the FASB issued ASU 2025-06, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software, which is intended to clarify and modernize the accounting for costs related to internal-use software. This ASU changes capitalization requirements from being tied to development stages and instead creates a capitalization threshold which is achieved when it is probable the software will be completed for its intended purpose. The annual and interim requirements for this ASU become effective for the Company on January 1, 2028. Early adoption is permitted and may be applied using a prospective, retrospective, or modified transition approach. The Company is assessing all aspects of the ASU, including adoption timing and transition method, and the expected impact on its condensed consolidated financial statements. Adopted In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which is intended to improve the transparency of income tax disclosures by requiring consistent categories and greater disaggregation of information within the income tax rate reconciliation and income taxes paid disclosures. It also includes certain other amendments intended to improve the effectiveness of income tax disclosures. Specifically, this ASU requires a tabular income tax rate reconciliation using both percentages and amounts disaggregated into specific categories with certain reconciling items at or above 5% of the statutory tax, further disaggregated by its nature and/or jurisdiction. Additionally, income taxes paid will be required to be presented by federal, state, local and foreign jurisdictions, including amounts paid to individual jurisdictions representing 5% or more of the total income taxes paid. This ASU became effective for the Company on January 1, 2025, at which time it was adopted. The Company will include the required disclosures within its Annual Report on Form 10-K for the year ended December 31, 2025. Other Legislation Pillar Two On October 8, 2021, the Organisation for Economic Co-operation and Development (‘OECD’) announced an international agreement with more than 140 countries to implement a two-pillar solution to address tax challenges arising from the digitalization of the economy. The agreement introduced rules that would result in the reallocation of certain taxing rights over multinational companies from their home countries to the markets where they have business activities and earn profits, regardless of physical presence (‘Pillar One’) and introduced a global corporate minimum tax of 15% for certain large multinational companies starting in 2024 (‘Pillar Two’). On December 20, 2021, the OECD/G20 Inclusive Framework on Base Erosion and Profit Shifting released the Model Global Anti-Base Erosion (‘GloBE’) rules (the ‘OECD Model Rules’) under Pillar Two. On December 12, 2022, E.U. member states reached an agreement to implement Pillar Two and this agreement requires E.U. member states to enact domestic legislation to put Pillar Two into effect. In 2023, many E.U. countries enacted the necessary legislation (based on the OECD Model Rules) to implement Pillar Two in 2024. Ireland, in particular, enacted Pillar Two legislation by signing Finance (No. 2) Bill 2023 into law in December 2023. Other countries and territories have indicated they will introduce Pillar Two legislation beginning in 2025. The Pillar Two minimum tax is treated as a period cost beginning in 2024 and does not have a material impact on the Company's financial results of operations for the periods presented. The Company continues to monitor evolving tax legislation as well as additional guidance to enacted legislation in the jurisdictions in which we operate. H.R. 1 On July 4, 2025, the ‘Act to provide for reconciliation pursuant to title II of H. Con. Res. 14’ (‘H.R. 1’) was enacted into law and generally becomes effective on January 1, 2026, with certain exceptions. H.R. 1 included numerous changes to existing tax law affecting businesses, including extending and modifying certain key provisions of the Tax Cuts and Jobs Act of 2017, both domestic and international, expanding certain Investment Retirement Account incentives while accelerating the phase-out of others. The Company will continue to evaluate the overall impact of H.R. 1 and related regulations on our operations and tax positions and does not expect H.R. 1 to have a material impact on its financial results of operations.
