Liquidity and capital allocation: Cash and cash equivalents were $778 million and short-term investments were $369 million; $120 million of these operating funds was restricted. Fiduciary assets totaled $16.307 billion, including $6.901 billion in client funds, and were matched by fiduciary liabilities; these funds are not available for general corporate use.

Material changes and unusual items
- Operating expenses rose 9% to $9.591 billion. Compensation and benefits increased 7%, consistent with organic revenue growth, while other general expense included a $197 million charge for actual or anticipated legal settlements, principally related to Vesttoo matters.
- Aon recorded $135 million of expenses for the new Accelerating Aon United restructuring program. Reported operating margin declined despite growth in operating income; adjusted margin excludes specified costs, including restructuring, intangible amortization, legal settlements, and transaction costs.
- Interest expense increased 19% to $484 million, primarily due to higher debt and interest rates. The effective tax rate rose to 17.1% from 16.2%.
- Capital expenditures increased to $252 million from $196 million. Cash used in financing activities rose to $2.865 billion, reflecting repurchases, dividends, debt activity, and other financing items.
Outlook, risks, and contingencies
- Outlook: The filing does not provide a specific 2024 revenue or EPS forecast. Management said it expects operating cash flows, available cash, credit facilities, and capital markets to meet liquidity needs, including the NFP acquisition. Aon expects approximately $68 million of pension contributions in 2024.
- Restructuring: The three-year Accelerating Aon United program is expected to cost about $1.0 billion ($900 million cash and $100 million non-cash) and produce about $350 million in annualized savings by the end of 2026. Aon cautions that costs, timing, and savings may differ from estimates.
- NFP acquisition: Under the December 2023 agreement, Aon agreed to acquire NFP for approximately $7 billion in cash and 20 million Aon shares, subject to adjustments and regulatory and other closing conditions. Closing was expected by mid-2024. Aon expected to fund the cash portion with about $7 billion of new debt; a $2 billion term-loan facility was committed in February 2024. Risks include approval or closing delays, financing costs, integration, employee and client retention, and failure to realize expected benefits. Certain termination circumstances could require a $250 million fee.
- Legal and regulatory: Aon recognized $197 million of fourth-quarter 2023 legal settlement expenses related to transactions involving allegedly fraudulent letters of credit arranged through Vesttoo; it said a potentially significant amount may be recoverable. Related claims and regulatory matters remain unresolved, and Aon states that some loss ranges cannot be estimated. The filing also describes other significant litigation, including claims arising from a 2016 aircraft crash.
- Credit and financial risks: At year-end, S&P rated senior debt A- with a negative outlook, Fitch BBB+ with a negative outlook, and Moody’s Baa2 with a stable outlook. Key exposures include debt refinancing and servicing, foreign exchange, interest rates, pension funding, tax uncertainty including Pillar Two implementation beginning in 2024, and potential volatility in client and insurance markets.
- Operating risks: The filing highlights intense competition, retention of skilled personnel, technology and cybersecurity incidents, privacy obligations, third-party service-provider reliance, E&O claims, and effects of economic, geopolitical, and climate-related disruptions. Aon reported past cybersecurity incidents but said they had not materially affected its business, strategy, results, or financial condition.
