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. Joining me on the call is Mark McGivney, our CFO; and the CEOs of our businesses: Martin South of Marsh, Dean Klisura of Guy Carpenter, Martine Ferland of Mercer, and Nick Studer of Oliver Wyman. Also, with us this morning is Sarah Dewitt, Head of Investor Relations. Before I get into our results, I'd like to take a moment to comment on the violent attacks on Israel and the tragic events unfolding in Israel and Gaza. We, along with our colleagues, condemn all acts of terror and violence and reject hatred. Our primary focus is on ensuring the safety and well-being of our colleagues in Tel Aviv and supporting colleagues around the world who have family and friends in Israel and Gaza. We're also supporting our clients as they grapple with the challenges of this conflict. Turning to our third quarter results. I'm very pleased with our performance. We extended our best run of quarterly underlying revenue growth in over two decades and reported significant growth in adjusted EPS. Top-line momentum continued with 10% underlying revenue growth, on top of 8% growth in the third quarter of last year. Adjusted operating income grew 24% versus a year ago. Our adjusted operating margin expanded 170 basis points compared to the third quarter of 2022. Adjusted EPS grew 33%, and we completed $300 million of share repurchases during the quarter. These results reflect our consistent focus on delivering in the near term, while investing for sustained growth over the long term. We are seeing the benefit of investments we've made in our talent and capabilities, and we continue to see opportunities to add high-quality acquisitions. During the third quarter, we announced two significant transactions. In early August, Marsh McLennan Agency acquired Graham Company, a top 100 U.S. insurance and benefits broker and risk management consultancy with 215 employees and over $70 million in revenue. Graham will provide significant business insurance and employee benefits expertise for MMA's clients in the Mid-Atlantic. This acquisition is another example of us attracting the best agencies in the U.S. MMA is now a $3 billion revenue business. In the same month, Marsh announced an agreement to acquire Honan Insurance Group. This deal expands our Australian middle market business and our position across the Pacific region and Asia. Honan specializes in corporate risk and employee benefits and serves over 30,000 clients. Beyond acquisitions, we continue to make targeted investments in talent, sales operations, and go-to-market strategies. We are also investing in new technologies and solutions to bring the best of Marsh McLennan to our clients. For example, Guy Carpenter recently launched the next generation of our catastrophe analytics platform, GC Advantage Point. The new platform is a critical tool to help clients drive profitable risk selection and manage catastrophe exposure in a quickly evolving risk landscape. Earlier this year, Marsh announced the launch of Cyber Pathway, an integrated cybersecurity and insurance solution for U.S. small and midsized businesses that helps enhance the resilience in a volatile threat environment. The program provides access to key security tools and capabilities as well as insurance coverage that can grow as our clients evolve. And we are investing in technologies that enhance our internal productivity, insights for clients and improve colleague experience. One example is LenAI, Marsh McLennan's internal AI assistant. LenAI offers the power of ChatGPT in a safe and data-secure environment and is available to all colleagues. Developed by our innovation center, it's also helping Oliver Wyman support clients in developing their own AI capabilities. Our approach to balancing investment and growth drives consistent exceptional performance for shareholders and positions us well to deliver new solutions and insights for our clients. Turning to our strategic initiatives. The combined value proposition of our businesses continues to gain traction with clients, especially in certain industries and lines of business. For example, we are focused on enterprise risks for healthcare clients. Our Marsh and Mercer teams are coming together to respond to emerging challenges, such as health and safety, labor actions, and workforce and liability risks from AI. In the private equity and M&A space, Mercer, Marsh, and Oliver Wyman are combining capabilities to help client’s close deals and create post-transaction value. This can include due diligence, advisory on large transformations, health and benefits carve-out transactions, and providing stop-loss solutions. And in the insurance sector, Guy Carpenter is partnering with Mercer to provide portfolio management solutions to insurance clients. One example is our advanced balance sheet solution, which is a collaborative approach that aligns risk and return across an insurer's balance sheet. This offering has already resulted in several regional insurers choosing to partner with Mercer for OCIO. We are also finding new ways to operate, reduce complexity, and organize for impact. As we continue to execute on our restructuring actions, we've identified additional opportunities to rationalize technology, reduce our real estate footprint, and realign our workforce. We now expect to achieve total savings of roughly $400 million by 2024, with total cost to achieve these savings of $425 million to $475 million. Overall, the momentum we are seeing as our businesses increasingly serve clients together, combined with our restructuring efforts, offers opportunities to deliver enhanced value for clients, drive higher growth, and be more efficient and connected. Now let me turn to the macro environment. The outlook remains uncertain. Capital market volatility has returned with the continued rise in interest rates. The trajectory of inflation and further central bank tightening remain an open question and the geopolitical situation remains volatile. Despite the environment, we continue to perform well, and we have a track record of resilience. We believe we are well positioned to perform across economic cycles and manage our business to grow revenues faster than expenses in good as well as challenging periods. Now let me turn to insurance and reinsurance market conditions. Primary insurance rates continue to increase with the Marsh Global Insurance Market Index up 3% overall, in line with the second quarter. Property rates increased 7% compared to 10% in the second quarter. Casualty pricing was up in the low single-digit range. Workers' compensation increased slightly, while financial and professional liability insurance rates were down mid-single digits. Cyber insurance pricing decreased modestly after several years of increases. In reinsurance, our clients have faced consistent challenges throughout 2023. This includes elevated cat losses, core and social inflation, and continued political instability. As we look to January 1, the market appears to be more orderly than last year, but we expect underwriting discipline to continue. On the property side, we expect firm pricing, but a more stable market with adequate capacity and increased reinsurer appetite. In casualty, the market is more cautious with reinsurers assessing prior year loss development and inflation. We expect capacity to remain stable. Overall, clients will need thorough preparation and a proactive strategy to achieve desired outcomes. We are well-positioned to help our clients navigate these dynamic market conditions. Now let me turn to our third quarter financial performance. We generated adjusted EPS of $1.57, which is up 33% from a year ago. On an underlying basis, revenue grew 10%. Underlying revenue grew 11% in RIS and 9% in Consulting. Marsh was up 8%, Guy Carpenter 8%, Mercer 8%, and Oliver Wyman grew 12%. Overall, the third quarter saw adjusted operating income growth of 24% and our adjusted operating margin expanded 170 basis points year-over-year. For the nine months, consolidated revenue grew 10% on an underlying basis. Adjusted operating income grew 17% and our adjusted operating margin expanded 130 basis points. Adjusted EPS was $6.31, up 17% from a year ago. With our outstanding results in the third quarter and year-to-date, we remain on track for a terrific year. Based on our outlook today and assuming current market conditions persist, we now expect full-year underlying revenue growth to be 9% to 10%. We also continue to expect margin expansion for the full year and strong growth in adjusted EPS. Finally, I want to provide an update on our recently announced leadership changes. Martine Ferland, CEO of Mercer, will retire on March 31 of next year. Pat Tomlinson has been appointed President of Mercer, where he will work closely with Martine through a transition period and have responsibility for Mercer's global health, wealth, and career practices. Pat will succeed Martine as President and CEO of Mercer upon her retirement. I'm excited to work with Pat in his new role. He brings an outstanding track record as a leader and strong knowledge of our business. He currently serves as Marsh McLennan, U.S. and Canada CEO; and Mercer President of U.S. and Canada; has had 26 years of industry experience, including the last nine years in leadership roles at Mercer. I also want to thank Martine for her leadership. In her five years as CEO of Mercer, she delivered strong growth, built and cultivated our talent, and delivered impact for our clients. This announcement is another example of our depth of exceptional talent and focus on succession planning. Overall, I am proud of our third quarter performance, which demonstrates continued execution of our strategy and continued momentum across our business. I'm grateful to our colleagues for their focus and determination and the value they deliver to our clients, shareholders, and communities. With that, let me turn it over to Mark for a more detailed review of our results.
