Restructuring and Related Activities [Abstract] |
Accelerating Aon United Program | Accelerating Aon United Program In the third quarter of 2023, Aon initiated a three-year restructuring program called the Accelerating Aon United Program (the “Program”) with the purpose of streamlining the Company’s technology infrastructure, optimizing its leadership structure and resource alignment, and reducing the real estate footprint to align to its hybrid working strategy. The Program will include technology-related costs to facilitate streamlining and simplifying operations, headcount reduction costs, and costs associated with asset impairments, including real estate consolidation and technology costs. Program charges are recognized within Accelerating Aon United Program expenses on the accompanying Condensed Consolidated Statements of Income and consists of the following cost activities: •Technology and other – includes costs associated with actions taken to rationalize certain applications and to optimize technology across the Company. These costs may include contract termination fees and other non-capitalizable costs associated with Program initiatives, which include professional service fees. •Workforce optimization – includes costs associated with headcount reduction and other separation-related costs. •Asset impairments – includes non-cash costs associated with impairment of assets, as they are identified, including ROU lease assets, leasehold improvements, and other capitalized assets no longer providing economic benefit. The Program is currently expected to result in cumulative costs of approximately $1.0 billion, consisting of approximately $900 million of cash charges and approximately $100 million of non-cash charges. For the three months ended March 31, 2024, total Program costs incurred were $119 million. The Company expects to continue to review the implementation of elements of the Program throughout the course of the Program and, therefore, there may be changes to expected timing, estimates of expected costs, and related savings. The Company’s unpaid liabilities for charges under the Program are generally included in Accounts payable and accrued liabilities in the Condensed Consolidated Statements of Financial Position. The changes in the Company’s liabilities for the Program as of March 31, 2024 are as follows (in millions):
