WILLIS TOWERS WATSON PLC New Standards Disclosure

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. In response to the SEC’s discontinuation of its defense of the SEC Climate Rules, the pending litigation is held in abeyance, awaiting the SEC to either defend, revise, or rescind the rules. The Company is monitoring the outcome.

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 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 became effective for the Company on January 1, 2026. Early adoption was permitted and the guidance was applied prospectively to estimates of expected credit losses on asset balances prepared after the date of adoption. The Company did not early-adopt this ASU and does not expect the ASU to have a material impact on its 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 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 are 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 has included the required disclosures within Note 7 — Income Taxes.
