Thanks, Andrew. Good morning, and thank you for joining us to discuss our third quarter results reported earlier today. I'm John Doyle, President and CEO of Marsh & McLennan Companies, Inc. On the call with me is Mark McGivney, our CFO, and the CEOs of our businesses: Martin South of Marsh, Dean Klisura of Guy Carpenter, Pat Tomlinson of Mercer, and Nick Studer of Oliver Wyman. Also with us this morning is Jay Gelb, Head of Investor Relations. Marsh & McLennan Companies, Inc. had a solid third quarter. As we said coming into the year, we anticipated impacts from a changing macro environment, and our performance continues to track with our expectations. Overall, we grew revenue 11% in the quarter, reflecting continued momentum in our business and contributions from an active year of acquisitions in 2024. Underlying revenue increased 4% for the quarter, reflecting the impact of lower fiduciary interest income, declining P&C pricing, and economic uncertainty affecting our clients, especially in the U.S. Adjusted operating income increased 13% from a year ago. Our adjusted operating margin increased 30 basis points compared to 2024, and adjusted EPS grew 11%. Earlier this week, we announced that we will change our brand in January from Marsh & McLennan Companies, Inc. to Marsh. Also in January, our stock ticker symbol on the New York Stock Exchange will change from MMC to MRSH. Our businesses will adopt the Marsh brand after a transition period. We also introduced Business and Client Services, or BCS. This unit brings together our operations and technology teams from across the company under Paul Beswick, our Chief Information and Operations Officer. Our new brand strategy, the creation of BCS, and the efficiencies we expect to gain are core parts of a new program we call Thrive. Thrive will also include automation efforts and workforce actions to optimize our scale and specialization. The program is designed to deliver greater value to clients, accelerate growth, and improve efficiency. The efficiencies we gained through the program will support investments in talent and technology. As we increasingly deploy AI, we can deliver even greater value for clients and colleagues. Thrive will also help us continue to expand margins. Let me take a moment to comment on our brand strategy. Marsh will be our new brand and represent our vision to be the most impactful professional services firm in the world. This change will increase our visibility, strengthen our value proposition, and support our business strategy. The Marsh brand is highly regarded and has the broadest global reach among our businesses. Today, Marsh stands for excellence in risk advising and insurance broking. Going forward, the new Marsh will represent the full value of our offerings in risk strategy and people. Turning to BCS, our company has a long history of innovation, which has been an important factor in our success for over 150 years. We continue to innovate in the AI era, having invested in large language models for more than two years. And while the full impact of AI is still emerging, we are seeing an increase in opportunities from our use cases. We are focused on developing tools that boost colleague productivity to better support our clients. For example, Len.ai, our proprietary Gen.ai tool for colleagues, responds to about 1,000,000 inquiries per week, fueling efficiency and automation. We are also rolling out new market-facing AI tools, including most recently, AIDA. This is Mercer's proprietary AI-powered assistant within the Talent All Access portal, which is a global intelligence platform supporting HR decision-making. And prior to AIDA, we introduced Centrisk, our AI-enabled supply chain risk assessment platform. We have a vast data set as the global leader in risk strategy and people, and BCS will accelerate our efforts to extract valuable insights through AI and analytics. This enables us to better serve our clients, empower our colleagues, and increase our efficiency. Over the next three years, we expect Thrive will generate approximately $400 million in savings, with a portion being reinvested to drive additional growth. We will incur around $500 million in charges to achieve these savings. Now I'd like to take a moment to talk about talent in the insurance and reinsurance markets. This is a people business, and we have an unmatched depth of talent with over 90,000 colleagues. And we love to compete because it makes us better. Colleague mobility is good for our industry and has served us well because we are an employer of choice, with a strong colleague value proposition. Our colleagues can be their best at our company because they work with the top talent in our industry, they manage meaningful client issues, and they have access to market-leading analytics and technology. We make a point of differentiating ourselves through a collaborative team-based model. This is reflected in strong colleague retention and excellent engagement scores. A few competitors have engaged in unlawful and unethical hiring practices and encourage talent to violate their covenants as a deliberate strategy to build their businesses. In these cases, I believe it's important to call out this behavior and to protect our rights. It's also the right thing to do to sustain the trust that we've built with our clients over a long time. Turning to insurance and reinsurance market conditions, we continue to see a competitive market characterized by slower growth from an uneven economy, stronger carrier ROEs, and continued decreases in overall rates, particularly in property reinsurance and property cat reinsurance. According to the 4% in the third quarter driven by property, this follows a 4% decline in 2025. As a reminder, our index skews the large account business. Overall, rates were down in the U.S. by 1%, Canada was down 3%, the UK, EMEA, Latin America, and Asia were all down mid-single digits, and Pacific was down by double digits. Global casualty rates increased 3% with U.S. excess casualty up 16%, reflecting continued pressure in the liability environment. Workers' compensation decreased by 5%. Global property rates decreased by 8% year over year, compared with a 7% decline last quarter. Global financial and professional liability rates were down 5% while cyber decreased 6%. In reinsurance, the market remains resilient. It has responded to an extended period of elevated natural catastrophe losses, as well as ongoing geopolitical and macroeconomic uncertainty. Dedicated reinsurance capital is projected to reach approximately $650 billion by year-end 2025. With ample capacity, increased competition is driving reinsurers to look for profitable ways to deploy capacity. The cap on market is on pace for a record year of issuance, with over 60 new bonds in the first nine months, generating approximately $17.5 billion of limit. In casualty reinsurance, renewals were largely stable with sufficient capacity. This outcome reflects underwriting actions of primary carriers and increased reinsurer appetite. Across both insurance and reinsurance, we advise our clients on proactive strategies that reflect the risk environment and market conditions, and of course tailored to their tolerance for volatility. Today, we see decreasing property casualty prices, but also a growing cost of risk. Over time, this trend is unsustainable. With that being said, barring significant changes in large loss activity, as well as the broader macro environment, we anticipate insurance and reinsurance market conditions seen so far this year will likely continue in 2026. Now let me turn to our third quarter financial performance and outlook, which Mark will cover in more detail. Consolidated revenue increased 11% to $6.4 billion and grew 4% on an underlying basis with 3% growth in RIS and 5% growth in consulting. Marsh was up 4%. Guy Carpenter grew 5%. Mercer 3%, and Oliver Wyman was up 8%. We had adjusted operating income growth of 13% and we generated adjusted EPS in the quarter of $1.85, which was up 11% from a year ago. We also repurchased $400 million of our stock in the quarter. Turning to our outlook for 2025, we continue to expect to deliver mid-single-digit underlying revenue growth, solid growth in adjusted EPS, and our eighteenth consecutive year of reported margin expansion. Of course, this outlook is based on conditions today, and the economic backdrop could turn out to be materially different than our assumptions. In summary, we're pleased with our year-to-date performance in a complex environment. Thrive will amplify our value proposition for clients across all our businesses, and it creates opportunities to invest in talent, growth, AI, and our new brands. Our capabilities are unique, and there is strong demand for our advice and solutions. We've earned our leadership position in our markets through 154 years of innovation and growth. Our disciplined approach to investing for the future while delivering results in the near term remains a guiding principle for our planning and capital allocation. Our announcements today and earlier this week align with this philosophy. With that, I'll hand the discussion over to Mark for a more detailed review of our results.
