Certain items that impacted fourth quarter results and comparisons with the prior year period are detailed in "Reconciliation of Non-GAAP Measures - Operating Income and Diluted Earnings Per Share" on page 10 of this press release.

This gives us confidence in our ability to build even greater momentum in 2022."

FOURTH QUARTER 2021 FINANCIAL SUMMARY

Total revenue in the fourth quarter increased 4% to $3.1 billion compared to the prior year period driven by 10% organic revenue growth, partially offset by a 5% unfavorable impact from divestitures, net of acquisitions, and a 1% unfavorable impact from foreign currency translation.

Total operating expenses in the fourth quarter decreased 6% to $2.1 billion compared to the prior year period due primarily to a $200 million positive impact from the repatterning of discretionary expenses within the year, as described in previous periods, a $64 million decrease in expenses related to divestitures, net of acquisitions, a $44 million decrease in transaction costs, and a $12 million favorable impact from foreign currency translation, partially offset by an increase in expense associated with 10% organic revenue growth and investments in long-term growth.

Foreign currency translation in the fourth quarter had a $6 million, or $0.03 per share, unfavorable impact on U.S. GAAP net income and a $7 million, or $0.03 per share, unfavorable impact on adjusted net income. If currency were to remain stable at today's rates, the Company would expect an unfavorable impact of approximately $0.16 per share, or an approximately $48 million decrease in operating income, in the first quarter of 2022.

Effective tax rate used in the Company's U.S. GAAP financial statements for the fourth quarter was 15.7%, compared to 14.7% in the prior year period, primarily driven by changes in the geographical distribution of income and a net favorable impact from discrete items. After adjusting to exclude the applicable tax impact associated with certain non-GAAP adjustments, the adjusted effective tax rate for the fourth quarter decreased to 12.2% compared to 13.4% in the prior year period, also primarily driven by changes in the geographical distribution of income and a net favorable impact from discrete items. The prior year period also included a net favorable impact from discrete items. These adjustments are discussed in "Reconciliation of Non-GAAP Measures - Operating Income and Diluted Earnings Per Share" on page 10 of this press release.

Weighted average diluted shares outstanding decreased to 221.2 million in the fourth quarter compared to 230.9 million in the prior year period. The Company repurchased 6.7 million Class A Ordinary Shares for approximately $2.0 billion in the fourth quarter. As of December 31, 2021, the Company had approximately $1.7 billion of remaining authorization under its share repurchase program.

The full year 2021 cash flow summary provided below includes supplemental information related to free cash flow, which is a non-GAAP measure that is described in detail in "Reconciliation of Non-GAAP Measures - Organic Revenue Growth and Free Cash Flow" on page 9 of this press release.

Cash flows provided by operations for 2021 decreased 22%, or $601 million, to $2,182 million compared to the prior year primarily driven by the $1 billion termination fee payment and additional payments related to terminating the combination with WTW, partially offset by strong revenue growth.

Free cash flow for 2021, defined as cash flow from operations less capital expenditures, decreased 23%, or $597 million, to $2,045 million compared to the prior year, reflecting a decrease in cash flows from operations as described above, partially offset by a $4 million decrease in capital expenditures.

Explanation of Non-GAAP Measures

This communication includes supplemental information not calculated in accordance with generally accepted accounting principles in the U.S. ("GAAP") related to organic revenue growth, free cash flow, adjusted operating income, adjusted operating margin, adjusted net income from continuing operations, adjusted earnings per share for continuing operations, and adjusted effective tax rate that exclude the effects of intangible asset amortization, restructuring, capital expenditures, and certain other noteworthy items that affected results for the comparable periods. Organic revenue growth includes the impact of intercompany activity and excludes foreign exchange rate changes, acquisitions, divestitures, transfers between revenue lines, fiduciary investment income, and gains or losses on derivatives accounted for as hedges. The impact of foreign exchange is determined by translating last year's revenue, expense, or net income at current period foreign exchange rates. Reconciliations to the closest GAAP measure for each non-GAAP measure presented in this communication are provided in the attached appendices. Supplemental organic revenue growth information and additional measures that exclude the effects of certain items noted above do not affect net income or any other GAAP reported amounts. Free cash flow is cash flows from operating activity less capital expenditures. The effective tax rate, as adjusted, excludes the applicable tax impact associated with expenses for estimated intangible asset amortization, restructuring, and certain other noteworthy items, such as the change to U.K. corporate income tax. Management believes that these measures are important to make meaningful period-to-period comparisons and that this supplemental information is helpful to investors. Management also uses these measures to assess operating performance and performance for compensation. Non-GAAP measures should be viewed in addition to, not in lieu of, Aon's Condensed Consolidated Financial Statements. Industry peers may provide similar supplemental information regarding their performance, although they may not make identical adjustments.
