Revenue

  
In April 2017, the FCA announced an investigation relating to suspected competition law breaches in the aviation and aerospace broking industry, which, for Aon in 2016, represented less than $100 million in global revenue. The European Commission assumed jurisdiction over the investigation in place of the FCA, and the European Commission has now closed its investigation. Other antitrust agencies outside the E.U. are conducting formal or informal investigations regarding these matters. Aon intends to work diligently with all antitrust agencies concerned to ensure they can carry out their work as efficiently as possible. At this time, in light of the uncertainties and many variables involved, Aon cannot estimate the ultimate impact on our company from these investigations or any related private litigation, nor any damages, penalties, or fines related to them.Settled/Closed MattersA retail insurance brokerage subsidiary of Aon was sued on September 6, 2018 in the United States District Court for the Southern District of New York by a client, Pilkington North America, Inc., that sustained damage from a tornado to its Ottawa, Illinois property. The lawsuit sought between $45 million and $85 million in property and business interruption damages from either its insurer or Aon. The insurer contended that insurance proceeds were limited to $15 million in coverage by a windstorm sub-limit purportedly contained in the policy procured by Aon for Pilkington. The insurer therefore tendered $15 million to Pilkington and denied coverage for the remainder of the loss. Pilkington sued the insurer and Aon seeking full coverage for the loss from the insurer or, in the alternative, seeking the same damages against Aon on various theories of professional liability if the court found that the $15 million sub-limit applied to the claim. In June 2022, the case was settled with no admission of liability on the part of Aon. In July 2022, Pilkington voluntarily dismissed all claims against Aon pursuant to the settlement.Aon Investments and AGI were sued on September 16, 2020, in the U.S. District Court for the Southern District of New York by the Blue Cross and Blue Shield Association NEBC. Aon Investments and its predecessors provided investment advisory services to NEBC since 2009. The NEBC contended that it suffered investment losses exceeding $2 billion in several Structured Alpha funds managed by AGI and recommended by Aon. The NEBC asserted claims against Aon Investments for breach of fiduciary duty and breach of co-fiduciary duty, and alleged that Aon Investments and AGI were jointly and severally liable for damages, which included the restoration of investment losses, disgorgement of fees and profits, and attorneys’ fees. In March 2022, the NEBC voluntarily dismissed all claims against AGI pursuant to a settlement between the NEBC and AGI. In August 2022, the case was settled with no admission of liability on the part of Aon. In September 2022, NEBC and Aon each voluntarily dismissed all claims remaining in the action, including all claims asserted by NEBC against Aon, and all claims asserted by Aon against NEBC and third-party defendants, pursuant to the settlement.Guarantees and IndemnificationsThe Company provides a variety of guarantees and indemnifications to its customers and others. The maximum potential amount of future payments represents the notional amounts that could become payable under the guarantees and indemnifications if there were a total default by the guaranteed parties, without consideration of possible recoveries under recourse provisions or other methods. These amounts may bear no relationship to the expected future payments, if any, for these guarantees and indemnifications. Any anticipated amounts payable are included in the Financial Statements, and are recorded at fair value.The Company expects that, as prudent business interests dictate, additional guarantees and indemnifications may be issued from time to time.Guarantee of Registered SecuritiesOn April 1, 2020, a scheme of arrangement under English law was completed, as described in the proxy statement filed with the SEC on December 20, 2019 (the “Ireland Reorganization”).
