Thank you, Oksana, and good morning, everyone. Thank you for joining us for our second quarter call. Changing weather patterns and persistent inflationary pressures have had a significant impact on our financial results during the first half of the year, prompting us to further accelerate our margin recapture plan, including additional catastrophe underwriting actions. The competitive landscape is changing rapidly in response to more frequent and severe convective storms and the continued inflationary pressures. In response, we are leaning into the hardest market we have seen in property, particularly in Personal Lines as we execute on our margin recapture plan. We are determined to fully leverage our deep market knowledge, underwriting expertise, enhanced tools and strong agency partnerships to address the unprecedented loss volatility in Property Lines of business. Our progress to date, our strong market position and our capable team give me the utmost confidence in our ability to succeed and deliver on the targets we conveyed at our Investor Day in 2021. We have a long history of successfully navigating challenging environments, and we are confident in our ability to do so going forward. With that theme in mind, I'll begin today's call with my perspective on the current dynamic environment and the significant catastrophe losses we experienced in the quarter and a review of the actions we are taking to restore property profitability. As part of our margin recapture and CAT management plans, including new initiatives we have underway. Jeff will review our financial and operating results in more detail and provide an update on our 2023 outlook, and then we will open the line for your questions. The catastrophe losses we and the industry have experienced in the second quarter are extraordinary. In particular, the record-breaking hail storms that impacted the Midwest and Southwest. Hail damage represented the vast majority of catastrophe losses we experienced in the quarter. The magnitude of those losses was amplified by persistent and ongoing inflation, which continued to drive up loss costs. Nearly half of our total losses in the second quarter occurred in Michigan, where we have our largest Personal Lines presence. By any measure, this kind of extensive and widespread CAT activity in the state of Michigan in a single quarter is very unusual. With weather patterns changing and costs elevated, we are highly focused on a broad set of integrated actions across our portfolio. The positive news is that we are operating in an extremely hard Personal Lines market, one that allows us to reset our pricing, meaningfully change terms and conditions and further refine our underwriting and risk appetite. With this in mind, we are highly focused on executing the margin recapture plan we initiated last year, responding with a sense of urgency. I'm pleased to report that we've made tangible and promising progress on our plan. We fully expect to build on that momentum. We have established driving improved and sustainable profitability going forward. Looking first at Personal Lines, we are taking a number of steps to optimize pricing on our renewal book and to ensure new business quality and pricing are stellar. Renewal pricing is clearly our most powerful lever. Year-to-date, we have received approval on 62 rate filings with 51 of those in the market and effective today, and we have a robust pipeline of additional filings, including 10 that are pending approval. With pricing increases of 22% in homeowners and 12% in auto during the second quarter, we are beating our own rate expectations by a couple of points. This differential is expected to grow to 3 to 4 points in the second half of the year in auto, while homeowners pricing beat will grow to 9 points, with an expected renewal price change of 27% in the fourth quarter. Not surprisingly, in the current Personal Lines hard market, retention has proved to be resilient, giving us even greater confidence in our enhanced profit improvement initiatives. The market has firmed meaningfully even since our last call three months ago. We are seeing the impact of the hard market across the competitive landscape through both public and mutual carriers and in all geographies, particularly in the Midwest. We have achieved very strong pricing increases in new business as market disruption has heightened quoting activity across Personal Lines. Since early 2022, our new business auto and home prices have risen by 30%. As a result, our current new business pricing is generally at or above renewal pricing levels, which reinforces our strong commitment to prioritizing profit improvement over growth. Additionally, we are becoming more restrictive as we quote new business, reducing our appetite in certain geographies, tightening our guidelines on driver history, and implementing stricter rules regarding building and roof conditions. We are also utilizing increasingly sophisticated tools to assist us on property evaluations such as aerial imagery and third-party data technology on every home to ensure new business quality, which is equally as critical as pricing adequacy. As a result of our pricing and underwriting actions, Personal Lines PIF growth is now flat on a sequential basis, and we expect it to shrink on a sequential monthly basis starting in the third quarter. Our Michigan PIF has been shrinking for some time now, and it is down 5% year-over-year. While rate and exposure increases are necessary and very effective in enhancing price adequacy of our CAT exposure, we believe specific product changes have the potential to have a very significant impact on reducing our future CAT vulnerability in Personal Lines. Recent hail events put a spotlight on the fact that houses and roofs in particular, are still a full value replacement-type product in many geographies, and we believe the industry is ready for a broader fundamental change. As such, we are taking the following three steps: First, we're increasing all payroll deductibles to specific minimum levels by coverage A limit; second, we're implementing wind inhaled deductibles in multiple states; and third, we're transitioning to actual cash value schedule for roofs as our standard offering with the intent to make more appropriate claims reimbursements for older roofs. While the industry has made advancements relative to diminishing roof valuations based on age and construction, we believe that pervasive hail storm events necessitate broad-based industry change. It's clear and important to note that older roofs are much more likely to be replaced post-hail events. As such, we will be mandating such coverage on older roofs in most states. These product changes will be implemented first on new business in the majority of our Personal Lines states. In fact, effective next month, we are changing defaults on comparative raters for new business, so that business transacted through comp raters reflects our current standards. Most states will require a filing and approval for renewal policy changes, which will take a little longer to execute. When fully implemented, these actions are expected to significantly reduce our CAT risk, vulnerability and future losses. To put this in perspective, a few examples will help showcase the expected impact. First, higher minimums on all peril deductibles will help increase cost sharing on CAT and non-CAT losses. Further, a 1% wind hail deductible would have the impact of more than doubling the deductible on a $500,000 coverage A homeowner risk and an ISO-based actual cash value roof schedule would reduce the claims cost by over 50% if a roof is over 15 years old. The cumulative effect of the actions we are taking in Personal Lines, including pricing, risk prevention and the fundamental change in our policy forms should materially reduce our Personal Lines catastrophe vulnerability and the volatility of our results. Moving on to Core Commercial. Once again, we've made meaningful progress in all three of our margin recapture plan focus areas: pricing, underwriting and risk prevention. In terms of pricing, we're leaning into the property hard market to push for even higher rate and exposure increases, which should help offset both elevated CAT and ex-CAT losses. Core Commercial property renewal pricing increased 12.6% in the second quarter. As of March, we automated insurance to value adjustments in small commercial, where appropriate, which are now set between 6% and 8% on top of rate increases and will increase overall renewal price change moving ahead. From an underwriting perspective, we took actions to reduce the volatility associated with property, particularly in middle market in 2022. We identified specific accounts with a higher likelihood of fire and other large loss volatility, and we completed appropriate nonrenewals in this business in April of 2023. We were very successful with that initiative as reflected in our current accident results for the second quarter. In 2023, we are now more closely addressing the pricing adequacy of our CAT exposures in light of persistent inflation and changes in weather patterns with our enhanced analytics, third-party data and CAT modeling. Specifically, we have identified approximately 5% of risks in our Core Commercial business that are most vulnerable to catastrophe losses. As we nonrenew or significantly reprice this business, we expect our retention to decline slightly or our pricing to increase significantly. In the second quarter, these planned actions drove a dip in middle market retention to just below 80%, and we're pleased with this trade-off. Consistent with our focus on loss control and risk prevention, we further expanded water and temperature sensor installation in 2023, resulting in an increase in avoided property damage and business interruption claims. We exhibited a 25% increase in protected accounts through the first quarter compared to the end of 2022. This figure has now doubled through the first six months of 2023. We learned a lot and are pleased with the effectiveness of the risk mitigation technology pilots through initial implementation over the last 18 months. With the success so far, enabling us to surge ahead toward even higher implementation targets this year. We will be implementing 2,500 to 5,000 new sensors in commercial lines accounts starting with 600 of our largest, most sophisticated and most exposed middle market accounts. These risks are targeted for installation this year, and we will continue to expand this program in the future. As a result of these actions, we anticipate the underlying ex-CAT loss ratio in our property book to further improve. While catastrophe outcomes are difficult to extrapolate, we believe that our actions when fully implemented will reduce our vulnerability to winter storm losses substantially. While our profitability improvement initiatives are already showing significant progress, the pace of progress is expected to accelerate in the coming quarters as these actions price in and new ones are implemented. Our Specialty book continues to perform exceptionally well, delivering robust pricing-driven growth and an exceptionally strong combined ratio in the quarter and year-to-date. The Specialty pricing environment is generally favorable overall, enabling us to achieve 11.4% price increase in the quarter. While the market environment in some of our segments is becoming more competitive, in particular management liability, our ability to deliver consistent profitability is a testament to our disciplined underwriting and rate strategy. The continued successful growth of our Specialty business is critical from a strategic perspective. This business provides important diversification for our overall portfolio and consequently reduces our property and CAT exposures, all while providing our agent partners with highly valued capabilities and business opportunities. The value of our Specialty portfolio to our agents and customers hinges on a highly competitive set of offerings, account-centric orientation, efficient service and coordinated relationship management. While our existing portfolio offers significant growth potential, our Specialty team is exploring complementary capabilities to support continued expansion of the business. For example, we are looking to further leverage technology to execute a low-touch small Specialty strategy and potentially to expand our Specialty appetite slightly to align more closely with our Core Commercial customer set, so we can further maximize the benefits of our account and industry specialization strategy. In conclusion, we remain committed to long-term profitability targets that are ambitious and achievable. We expect our ROEs to be strong in 2024, and to improve steadily through 2026. And we have every confidence we will be able to achieve our target profitability, potentially beating our long-term 14% ROE target. Supported by strong underwriting income and much higher than originally expected net investment income. We will, of course, continue to execute on our strategic priorities to continue expanding the top line. In the near term, profitability is our primary focus. With that, I will turn the call over to Jeff.
