Thank you, Oksana. Good morning, everyone, and thank you for joining us. I will begin today's call with my perspective on our third quarter results and a summary of the success we have achieved in our underlying margin recapture initiatives to date. A review of the actions we are taking to improve our catastrophe resiliency, including new initiatives we have underway. Jeff will review our financial and operating results in more detail, and then we will open the line for your questions. I'll begin by acknowledging the heavy impact of CATs on our third quarter results and the great sense of urgency with which we are executing on our CAT resiliency actions. I'll expand more on this topic shortly. Excluding catastrophes, we are very pleased with our third quarter performance. I'm happy to report that our third quarter ex-CAT results were slightly better than our expectations, in part due to the continued strong execution of our margin recapture plan, which helped to drive meaningful underlying improvement in all 3 of our business segments. Our progress in the quarter reflects the inherent strengths of our company, including our distinctive strategy and business model, broad and innovative capabilities, strong well-managed balance sheet, experienced and committed team and deep mutually beneficial partnering relationships with many of the best agents in our business. The last of these are deep agency relationships is particularly important today as we and others are thoughtfully increasing prices, modifying terms and conditions and tightening underwriting requirements. In keeping with our commitment to being a premier property casualty franchise in the independent agency channel, we are working closely with our agents and their teams to help them better respond to their customers and navigate today's challenges. At the same time, we are further leaning into one of the hardest markets we have seen in property, particularly in Personal Lines as we deliver on our margin improvement initiatives. Those factors, along with many others, give us a very high level of confidence in our ability to drive disciplined execution further and enhance profitability over time. Our third quarter ex-CAT results are a strong testament to the successful execution of our comprehensive margin recapture plan as well as the important work we are doing to get back to our expected performance levels. We continue to be focused on 3 main levers: Price increases, property underwriting enhancements, and loss control and risk prevention measures. In Personal Lines, margin improvement is driven by robust and accelerating earned price increases. Earned pricing is outpacing loss trends helping drive a 1-point improvement in Personal Lines current accident year loss ratio in the third quarter compared to the second quarter this year, primarily driven by Personal Auto. Auto collision loss trends remain elevated but we are seeing an easing of inflationary pressures, while prior rate increases are beginning to help drive improvement in our overall loss ratio. Homeowners loss pressure is proving to be an ongoing challenge. Having said that, we are confident continued price increases, on top of current increased earned rate and valuations, will bend the curve starting next quarter. Additionally, we are taking a more aggressive approach to homeowners non-renewals based on specific underwriting criteria, including quality of ROOF Score, prior loss experience and age of construction. Third quarter Personal Lines total price change in auto and home were up 14% and 23%, respectively. By the end of this year, we expect an average homeowners renewal price change upwards of 28%. Collectively, we expect Personal Lines to experience a dramatic profit recovery next year, and a return to our target profitability on a written basis at the end of 2024, based on a range of reasonable assumptions for loss trends. We also continue to execute on our profit improvement plan in Core Commercial property lines in the quarter across all 3 focus areas: Pricing, underwriting and risk prevention. In terms of pricing, our core Commercial Property renewal price increased by 14.7% in the third quarter, up 2 points from 12.6% in the prior quarter. We've also made meaningful strides in addressing large loss volatility in middle market, completing non-renewals and policy limit adjustments that have lowered our total property risks by 17% in constant dollars compared to 12 months ago. We also engaged in a range of risk prevention and mitigation initiatives designed to reduce both CAT and non-CAT losses in Core Commercial. We are successfully expanding the number of accounts enrolled in our IoT sensor program. We have increased the number of protected accounts by approximately 40% over the last 3 months and 175% since the end of 2022. Additionally, through the end of September, 30% of the 600 targeted middle market accounts have been addressed through underwriting actions or sensor deployment, and we'll continue to address additional accounts through the fourth quarter. These actions are now delivering results, reducing large loss volatility and improving our Core Commercial current year loss ratio by over 5 points compared to the third quarter last year. Turning to our Specialty business. We are very pleased with the performance across our portfolio, delivering a combined ratio of 83% for the quarter, ahead of our expectations. While market conditions in some of our segments are competitive, in particular for sectors like management liability. Our ability to deliver consistent profitability is a validation of our diversified specialty portfolio and disciplined underwriting and rate strategy. Our Specialty growth in the quarter was somewhat muted due to the temporary impact of non-renewals of a couple of underperforming programs. Despite ongoing excellent performance in Specialty, we expect all segments to contribute to the enterprise margin recapture plan, and we are also being proactive on any lines and segments that are sensitive to social inflation. Excluding programs, Specialty growth was 7.4% in the third quarter. Longer term, however, Specialty continues to represent a robust growth opportunity for our company. This business provides important diversification for our overall portfolio, and consequently, reduces our property and CAT exposures, all while providing our agent partners with robust comprehensive product offerings, highly valued capabilities and additional growth prospects. We fully expect our Specialty portfolio to return to upper single-digit growth starting in the first quarter next year, as we benefit from increased market penetration in most segments and growth in newer product offerings, including Specialty, GL and E&S business. We also expect additional lift from our newest initiatives, including expansion in the wholesale channel, which is already delivering solid growth. Now turning to our efforts to manage our catastrophe exposures more effectively in Personal Lines. We made important progress on the CAT exposure management actions we discussed on our second quarter call. These actions include increasing all peril deductibles to specific minimum levels determined by coverage A limits, implementing wind and hail deductibles in additional states, and transitioning to an actual cash value schedule for roofs in certain states and on specific risks for new business policies. As of September, the default for all payroll and wind and hail deductibles in the comparative raters for new business have been updated and our agents are supporting our efforts. These changes will be introduced in our TAP sales platform as a requirement on transactional new business as soon as next week. We also are advancing the technology and regulatory processes that enable us to expand these product changes to policy renewals starting in February, with our key states starting with April effective dates. We expect we will roll most of our homeowners business into new terms by the end of 2024. In addition, we are planning to introduce actual cash value for roofs in the comparative raters, starting in 2024 for new business in certain geographies and types of risks, thereby further reducing claims costs for older roofs. We expect these actions will enable us to better share loss costs with insureds, which should support loss prevention, decrease claim severity and minimize our exposure to aggressive roofer actions. We expect to see significant improvements in our CAT vulnerability and loss experience once these product changes are fully in place. At an individual risk level, we could realize upwards of 30% to 50% reduction in hail and roof claims payouts. For example, a wind and hail deductible on a $1 million coverage A, depending on the roof age, will range between $10,000 and $20,000 against an average roof claim cost of $35,000 to $40,000. At the same time, we expect to see the benefit of reduced claims frequency as the higher deductibles will ensure that only legitimate claims are filed. In addition to product and pricing changes, we are also reviewing our geographic exposures, and reevaluating our property micro concentrations. While we continue to believe some of the recent CAT losses for Personal Lines in the Midwest were aberrant, we are taking steps to reduce our property exposure in certain areas across these states, including but not limited to Michigan. We have updated our models and are reassessing our property aggregations to ensure we are not overly exposed in specific geographic areas in light of the increased property valuations and changing weather patterns. Additionally, we are achieving substantial decreases in exposure beyond PIF reduction from the product changes and risk prevention actions we are implementing. Longer term, we will continue our diversification efforts to emphasize Personal Lines growth in lower-concentration states. We also expect small commercial and Specialty exposure and policy counts to grow much faster than Personal Lines, and ultimately, to reduce the relative share of Personal Lines business in our overall mix. As we look ahead, we believe we have what it takes to succeed in a rapidly changing and challenging marketplace. We are very encouraged by our strong ex-CAT performance and the progress we have made on our margin recovery plan during the year. We look ahead with resolve and a high degree of conviction that we are executing the right set of initiatives to move our company forward. We have a proven strategy, 1 refined to meet the moment, 1 that will benefit our agent partners and customers, and 1 that positions our company to deliver sustainable, profitable growth and long-term value creation for our shareholders and other stakeholders. With that, I will turn the call over to Jeff.
