Thank you, Abby. Good morning, everyone, and thank you for joining us today. We are pleased to report excellent third-quarter results. We earned core income of $1.9 billion or $8.14 per diluted share. Our return on equity for the quarter was 22.6%, bringing our core return on equity for the trailing twelve months to 18.7%. Very strong underwriting results and higher investment income drove the bottom line. Underwriting income of $1.4 billion pretax more than doubled compared to the prior year quarter, benefiting from both the lower level of catastrophe losses and higher underlying underwriting income. The underlying result was driven by higher net earned premiums and an underlying combined ratio that improved 1.7 points to an exceptional 83.9%. Underwriting income was higher in all three segments. Our high-quality investment portfolio also continued to perform well, generating after-tax net investment income of $850 million for the quarter, up 15%, driven by strong and reliable returns from our growing fixed income portfolio. Our underwriting and investment results, together with our strong balance sheet, enabled us to return almost $900 million of capital to shareholders during the quarter, including $628 million of share repurchases. At the same time, we continue to make strategic investments in our business. Even after this deployment of capital, adjusted book value per share was up 15% compared to a year ago. With strong results over the past year and a particularly light cat quarter, we have a higher than usual level of excess capital and liquidity. Consequently, we anticipate a higher level of share repurchase over the next couple of quarters. Dan will have more to say about that in a minute. Turning to the top line, we grew net written premiums to $11.5 billion in the quarter. In business insurance, we grew net written premiums by 3% to $5.7 billion, led by 4% growth in our domestic business. Excluding the property line, we grew domestic net written premiums in the segment by more than 6%. The declining premium volume in property continues to be a large account dynamic. In fact, we grew property in both middle market and small commercial. We've seen this dynamic in the large property market before, and we won't compromise our underwriting discipline. Over time, particularly as catastrophic events inevitably unfold, the value of that discipline and the cost to those who abandon it will become unmistakable. Renewal premium and change in business insurance was 7.1%, driven by continued historically high RPC in our middle market and select business businesses. Excluding the property line, renewal premium change in the segment was a very strong 9%, and renewal rate change was a very strong 6.7%. Greg will share additional detail by line. Retention in the segment was 85%. Given the high quality of the book, we were very pleased with that result. In Bond and Specialty Insurance, we grew net written premiums to $1.1 billion with higher renewal premium change and continued strong retention of 87% in our high-quality management liability business. Net written premiums in our market-leading surety business remained strong. In personal insurance, written premiums were $4.7 billion with strong renewal premium change in our homeowners business. You'll hear more shortly from Greg, Jeff, and Michael about our segment results. As we head toward the end of the year, our planning for 2026 is well underway. As always, that process involves assessing the environment ahead. There are uncertainties out there: economic, political, geopolitical, not to mention the loss environment. We are very confident that we're built and very well positioned for whatever lies ahead. We're operating from a position of considerable strength. Profitability is strong, reflecting our leading underwriting expertise and the operating leverage we've built through a sustained focus on productivity and efficiency. Our competitive advantages have never been stronger or more relevant. Strong underwriting is the flywheel that sets everything in motion. Our premium growth at attractive margins has generated strong cash flow, which enables us to make strategic investments in our business, return excess capital to shareholders, and grow our investment portfolio. Since 2016, we have successfully invested $13 billion in technology, returned more than $20 billion of excess capital to our shareholders, and grown our investment portfolio by nearly 50% to more than $100 billion. Scale matters, increasingly so. We have the scale to win in an environment where technology and AI will continue to segment the marketplace. We have a track record of identifying the right strategic priorities and driving value from them. You can see that in the 300 basis point reduction we've achieved in our expense ratio since 2016, even while we were significantly increasing our overall technology spend. Importantly, our size gives us the data to power AI, creating a virtuous cycle: better insights, better decisions, better outcomes, more resources to invest. For example, our long-time focus on organizing and curating data has given us access to more than 65 billion clean data points from decades of history across multiple business lines. We leverage that to sharpen our underwriting and shape our claim strategies. With the vast majority of our business in North America, we hold a leading position in the largest and most stable insurance market in the world, an advantage that insulates us from much of the risk arising from the economic instability and geopolitical uncertainty around the globe. Our fortress balance sheet and exceptional cash flow provide us with the financial strength to invest consistently in the business regardless of the external conditions. Our financial strength also enables us to manage comfortably through large loss events like the January California wildfires. When it comes to the loss environment, from weather volatility to the impact of social inflation on casualty lines, no one is better positioned. Diversification provides powerful protection. In fact, our business mix produces a consolidated loss ratio that's actually less volatile than the loss ratio of our least volatile segment. That's the power of a balanced and diversified portfolio. Equally important is our demonstrated ability to confront the loss environment head-on. We have the data, the analytics, and the discipline to establish reserves and loss picks appropriately and generally ahead of the market. That matters because until you have an accurate view of the loss environment, your risk selection, underwriting, and claim strategies are all operating with the wrong inputs. Since our early identification of the acceleration of social inflation in 2019, we've grown the business and delivered significantly improved margins. Getting an accurate and timely view of the loss environment isn't just about the balance sheet. It's foundational to running the business effectively. Our internally managed investment portfolio was another source of strength. Our disciplined focus on achieving appropriate risk-adjusted returns has served us exceptionally well through various markets, especially during periods of market turmoil. More than 90% of our portfolio is in fixed income with an average credit rating of AA. We're highly selective. We don't reach for yield. We hold the vast majority of our fixed income securities to maturity. And we carefully coordinate the duration of our assets and liabilities. The track record speaks for itself. Our default rates during the most challenging environments over the past two decades were a fraction of industry averages. This consistency comes from a world-class investment team, with extraordinary tenure and a shared long-term perspective. In short, the franchise we've built, the capabilities we've developed, and our depth of expertise create advantages that are durable across operating environments. Before I wrap up, I'll share that we're just back from one of the industry's premier conferences, where we had the opportunity to meet with dozens of our key agents and brokers, who collectively represent a substantial amount of our business. We left as convinced as ever that our position with the independent distribution channel is an unmatched strategic advantage. We heard clearly that our strategic investments are resonating and that looking ahead, we're focused on the right priorities to extend that advantage. I want to acknowledge and thank all of our distribution partners. I also want to reiterate our unwavering commitment to being an indispensable partner for them and the undeniable choice for their customers. To sum it up, we're very well positioned and very optimistic about the road ahead. And with that, I'm pleased to turn the call over to Dan.
