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. 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 for her last quarter as Head of Investor Relations is Sarah DeWitt. We’d like to congratulate Sarah on her new role as Chief Financial Officer of Marsh. Before I get into our results, I’d like to take a moment to comment on Hurricane Helene and Milton, which have devasted communities in Florida and the Southeast United States. These events are first and foremost the human tragedy and our thoughts are with all of those impacted by the storms. Our primary concern has been the wellbeing of our colleagues and their families as well as our clients and we’re actively working to assist in their recovery. While the ultimate insured loss won’t be known for sometime the impact of these storms will be significant and given their wide paths of destruction and close timing they will put enormous pressure on resources available for recovery. Both hurricanes also highlight the meaningful disparity between economic loss and insured loss. According to some estimates, Helene may have the largest multiple of economic to insured loss of any U.S. storm. This protection gap imposes a meaningful burden on the economy, makes near-term recovery more challenging and undercuts resilience. In addition, rising frequency and severity of extreme weather events, higher property values and increased development in cat prone areas are driving the need for greater protection. We and the insurance industry help communities, businesses and governments build resilience to manage these perils. But as these storms highlight, there is opportunity to do more through risk mitigation, event preparedness and alternative solutions such as community based parametric products. Turning to our results, the third quarter marked another milestone for Marsh McLennan. We continue to perform well across our business and we were thrilled to announce the acquisition of McGriff Insurance Services. In the quarter, we generated 5% underlying revenue growth following 10% in the third of last year, reflecting solid execution in RIS and Consulting. We grew adjusted operating income 12%. Our adjusted operating margin expanded 110 basis points, adjusted EPS grew 4% or 11%, excluding a discrete tax benefit in the Q3 of last year and we completed $300 million of share repurchases in the quarter. Turning to McGriff, it is a leading provider of insurance broking and risk management services in the U.S. with approximately $1.3 billion in revenue. I have long admired McGriff. They have excellent leadership, talented colleagues and a track record of strong growth. Their deep specialty and industry capabilities will strengthen the value proposition and expand the reach of Marsh McLennan Agency in the vast and growing middle market segment. McGriff's client focus, culture of collaboration and commitment to excellence and integrity mirror our own. Together, McGriff and MMA will create new opportunities for colleagues to be their best and helping them delivers even greater value to clients. The $7.75 billion transaction will be funded by cash on hand and debt financing. We expect to close by year end, subject to regulatory approval. We would also expect the transaction to be modestly accretive to adjusted EPS, excluding amortization in year one and become more meaningfully accretive in year two and beyond. We have a terrific track record of acquiring and integrating businesses and we are excited to welcome McGriff's over 3,500 colleagues to the company when the deal closes. McGriff has added to what is already an active year for M&A across our business. We are on track record for the largest M&A year in Marsh McLennan's history, with nearly $10 billion of capital committed to acquisitions year to date, including McGriff, Vanguard's U.S. OCIO business, Cardano, Horton and FBBI. These acquisitions highlight our strategy to deploy capital to faster growing segments of our business. As we have said before, we consistently focus on delivering in the near-term, while investing for sustained growth over the long-term. Shifting to the macro environment, the overall backdrop remains supportive of growth despite what continues to be a complex and volatile landscape. Central banks have begun a cycle of easing and consensus views of the likelihood of near-term recession for most major economies are well below where they were coming into the year. We continue to see economic growth across most of our major markets. Inflation remains elevated, but declining. Labor markets remain healthy and the cost of risk in healthcare continues to rise. That said, uncertainty remains with rising geopolitical tensions and continuing conflicts in Ukraine and the Middle East. Clients across the world continue to assess the implications of technology advances in AI, the ever persistent threat from cyber-attacks, supply chain risk and the impact of increasing frequency and severity of extreme weather events on their businesses. Our talent, expertise and solutions help clients manage challenges and accelerate opportunities to thrive, so we remain positive in our outlook for growth. We are well positioned and have a track record of performing across economic cycles due to the enduring value we bring to clients and the resilience of our business. Turning to insurance and reinsurance market conditions, the Marsh Global Insurance Market Index was down 1% overall in the third quarter versus flat in the second quarter. Rates in the U.S. and Latin America were up low-single-digits. Europe was flat, and in the UK, Asia and Pacific rates were down mid-single-digits. Global property rates were down 2% versus flat in the second quarter, however, global casualty rates increased 6% with U.S. excess casualty up approximately 20% in the quarter. Workers' compensation decreased low-single-digits. Global financial and professional liability rates were down 7%, while cyber decreased 6%. In reinsurance, demand continued to rise and capacity remained adequate in the quarter. While it is too early to know the ultimate insured losses from hurricanes Helene and Milton, we expect there to be an impact on 2025 property insurance and reinsurance pricing. Cat bonds, which posted record volume in the first half, remain likely to have elevated issuance activity through year end, driven by a heavy maturity schedule and capacity for casualty programs is expected to be adequate despite concerns over the pace of lost cost inflation. As always, we are helping clients navigate these dynamic market conditions. Now, let me turn to our third quarter financial performance. We generated adjusted EPS of $1.63, which is up 4% from a year ago or 11%, excluding a $0.10 discrete tax benefit in the third quarter of last year. On an underlying basis, revenue grew 5%. Underlying revenue grew 6% in RIS and 4% in consulting. Marsh was up 7%. Guy Carpenter 7%, Mercer 5% and Oliver Wyman grew 1%. Overall in the third quarter, adjusted operating income grew 12% and our adjusted operating margin expanded 110 basis points year-over-year. For the nine months, consolidated revenue grew 7% on an underlying basis. Adjusted operating income grew 12%, and our adjusted operating margin expanded 110 basis points. Adjusted EPS was $6.93, up 10% from a year ago. Turning to our outlook, we are well positioned for another great year in 2024. We continue to expect mid-single-digit or better underlying revenue growth, another year of margin expansion and strong growth in adjusted EPS. Our outlook assumes current macro conditions persist. However, the environment remains uncertain and the economic backdrop could be materially different than our assumptions. Overall, I'm pleased with our Q3 performance, which demonstrates 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.
