The filing counts its colleagues by segment and by region (a), so the consulting, broking and corporate shares are stated counts.
The figures on this page come from the company's own annual report and from BLS staffing patterns for its industries, never from a roster. They are estimates with a stated method. Nothing here says what the company will do: within reach is not a forecast of jobs lost or of savings.

By the patterns, the work is about 67% desk work, 25% people work and 8% body work.

What the filing says about AI
14 sentences in the filing name AI. Fourteen sentences: incorporating AI into product offerings as increasingly important, the risk that generative and agentic AI may let clients do analytical, benchmarking, modeling and drafting work themselves and reduce demand for some services, and the risk of failing to keep pace.
- “For example, incorporating artificial intelligence ('AI') into certain product offerings is becoming more important in our operations, particularly as our competitors, including new entrants focused on using technology and innovation, such as generative or agentic AI, digital platforms, data analytics, robotics and blockchain, seek to simplify and improve the client experience, increase efficie...”
- “Additionally, rapid advances in generative and agentic AI may enable certain clients to perform internally, automate, or obtain through low-cost digital tools analytical, benchmarking, modeling, drafting or other work that they have historically relied on us to provide, which could reduce demand for some of our services and adversely affect our revenues and growth.”
- “If we fail to keep pace with rapidly evolving AI and other technological developments, our competitive position and business results may be negatively impacted.”
- “Certain AI use cases may generate inaccurate, biased or otherwise unreliable outputs or require enhanced human oversight, governance and controls, and evolving legal and regulatory frameworks may restrict how we collect, use and share data and deploy AI‑enabled tools.”
- “The use of third-party generative AI tools by our employees, contractors, consultants, vendors or service providers also presents a risk that confidential, personal or proprietary information could be inadvertently disclosed through prompts or uploads and incorporated into external models or training data, potentially compromising our ability to realize the benefit of, or adequately maintain, p...”
