Thank you, Oksana. Good morning, everyone, and thank you for joining our call. This morning, I'll begin with comments on our financial highlights for the year, our strategic accomplishments in 2019 and a high-level overview by business line. Jeff will provide an in-depth review of our financials and our outlook for 2020, and then we'll open the line for your questions. We are very pleased with our strong performance in 2019. We delivered an operating ROE of 12% and 12.8% after adjusting for the undeployed equity from the sale of Chaucer. We generated premium growth of 4.5% for the year, on the strength of our broad-based profitability across our portfolio and solid execution against our strategic imperatives. We continue to focus on our objective to be the premier property and casualty franchise in the independent agency channel, advancing our proven strategy, leveraging our position as an agency carrier of choice, our leading specialized capabilities and our commitment to innovation. We drive those distinctive elements of our strategy through our extraordinary talent and unique collaborative culture. During 2019, the property and casualty insurance industry environment exhibited even more complexity as profit pools, loss trends and rate movements continue to change more dynamically than ever before. Traditional market cycles have clearly given way to more sectoral and geographic forces that require more sophisticated and savvy approaches to underwriting, loss analysis and portfolio management. We demonstrated that we are developing an industry-leading ability to anticipate the market dynamics and react with agility and expertise in order to deliver strong results that foster continued momentum. We stayed focused on the ultimate goal delivering profitable growth and allocating capital and resources to our higher margin businesses. Turning to our financial highlights for the year. While the P&C industry is clearly experiencing higher overall loss trends, liability trends in our businesses, while certainly elevated, performed relatively consistent with our expectations. We believe that we have benefited from prior portfolio mix and pricing actions over the years, including reducing our exposure in major metropolitan areas, targeted underwriting actions and exiting all unsupported umbrella business. These actions are now helping us limit the impact of some of the industry headwinds, including social inflation and increased attorney involvement and should be beneficial as we head into 2020. In 2019, we also benefited from catastrophe experience that was more favorable than last year and below historical averages. In addition, we reduced our expense ratio beyond our initial expectations, while funding business investments with deliberate resource trade-offs and disciplined expense rigor. The year was not without its challenges. As we announced in mid-January, we saw elevated non-catastrophe property losses in the fourth quarter, not inconsistent with some of the activity we have seen earlier in the year. This was driven by a combination of non-cat weather activity in homeowners as well as higher incidences of property losses in CMP and certain specialty lines. Although the uptick in property losses over the past few quarters was consistent with industry trends, it was disappointing nonetheless. We have performed the appropriate due diligence on these businesses, and we maintain a high level of confidence that we have a quality portfolio and can make constructive adjustments in the current market to maintain our momentum. We believe that some of the loss pressure is likely a function of more extreme weather, high employment and a fairly robust economy, which is producing more activity-based losses. We are at the point in the economic cycle where we need to be especially prudent. We are taking actions in certain areas, including using targeted reinsurance tactics, changing terms and conditions and increasing rates. Now I'll update you on some key strategic accomplishments for the year, which fall into 5 categories: our business and agency mix, enhanced capabilities, technology innovation, talent development and capital allocation. First, our goal for the year was to continue to grow while improving profitability and reducing vulnerability to some of the more pronounced industry liability loss trends. We strengthened our portfolio by accelerating growth in our most profitable businesses, executing pricing actions in areas of need and reducing unprofitable areas, particularly programs in Commercial Auto. At the same time, we achieved profitable growth across key segments, such as Personal Lines, Small Commercial and middle market niches as well as certain Specialty Lines. We continue to enhance and build on our agency penetration. Transactional new business in Personal and Small Commercial continued to accelerate, demonstrating agency followership in the most profitable areas of our business. In addition, the number of agents that write over $5 million in total premium with us grew by 1/3 over the last 3 years. This agent cohort generates nearly 60% of our overall premium and delivers meaningfully better underwriting profits. At the same time, the number of agents that write more than 5 lines of business with us has increased over 25% since 2015, a testament to our broad product capabilities and the value they bring for our agents and customers. We also continue to appoint new agents and agency locations in 2019, mostly in our less-penetrated states. Over the last 3 years, new and expanded agency relationships generated more than $150 million in written premium. These strong mutually beneficial relationships with our agents enable us to navigate the dynamic market even more successfully together. Second, we continue to build out some of our newer products last year, including the depth and breadth of our E&S, cyber and financial institution businesses. We also enhanced our professional liability platform, Hanover Miscellaneous Professionals Advantage, building on our robust suite of professional liability solutions for our agents and insureds. In Personal Lines, we expanded our Hanover's Prestige brand across all of our Personal Lines markets in 2019, delivering high-value auto, home and condominium coverage to customers in all of our Personal Lines states. Our prestige brand generated strong premium growth in 2019. This growth provides further evidence that our whole account philosophy is resonating with our agents and their customers, improving our position as our agent partners carry of choice for preferred accounts. Third, we continue to invest in our underwriting and quoting platforms, while at the same time, driving innovation across our business. We are creating operational efficiencies and enhanced customer experiences across the entire insurance value chain through specific use cases, third-party data integration and process enhancements. Our targeted initiatives with Insurtechs and other plug-and-play options are delivering more insightful, innovative and efficient tools to our agents. Our investment in major underwriting and quoting platforms are now getting towards the tail end of the process. For example, our TAP sales platform has now been deployed to all of our Personal Lines states. Allowing for more granular pricing and underwriting and providing agents with a seamless quoting experience. We also are finalizing the build-out of our Small Commercial underwriting platform and plan to launch it throughout 2020 and 2021, along with our enhanced product offering. We believe both platforms will prove to be best-in-class and will enable us to more effectively interact with outside data sources and third-party digital tools for the benefit of our agents and customers. Additionally, we made important investments in our claims processes and capabilities, adding photo claims functionality to our adjusting process and various predictive modeling tools. This work enables us to enhance our operating efficiencies and take advantage of economies of scale in our claims functions, which will help us drive both loss and expense ratio improvements over time. We think this and other changes will benefit both our agents and customers. We have paid for the incremental cost of these projects through prudent expense management, including reductions in savings in less critical areas of our operations. This discipline is essential as digital capabilities are critical and constantly evolving, which requires continuous investment rather than large onetime capital expenditures. Fourth, attracting, retaining and developing our talented team is perhaps the most important ingredient in the success of any company in our industry. So I could not be more proud of the success we had on that front in 2019. For example, we expanded our Specialty leadership team and made new leadership appointments in Commercial Lines to oversee our middle market businesses as well as product and underwriting. We established new positions, including Chief Data and Analytics Officer and Chief Digital Officer to lead our overall efforts to use data, analytics and technology even more effectively and to create sustained value. Additionally, we strengthened our human resources team to lead our human capital strategy and further develop our culture of inclusiveness, agility, collaboration and innovation. Finally, in 2019, we continued to be prudent and accountable stewards of our shareholders' capital. Upon completion of the Chaucer sale at the end of 2018, we returned an initial $450 million of sale proceeds in the form of a $250 million accelerated share repurchase agreement and a $200 million special dividend. Over the course of 2019, as we continue to generate capital to fund organic growth opportunities, we distributed the remaining Chaucer proceeds through 2 additional ASR programs and a second special dividend. Moving forward, we will follow our normal capital management cadence and framework, using internally generated capital to support profitable growth and return the capital generated in excess of our growth needs to shareholders as warranted. Before I conclude my remarks, I will provide a high-level overview of our performance by business, beginning with Commercial Lines. We are very pleased with our Commercial Lines' progress and execution on strategic priorities in 2019. Our goal for the year was to grow, while adjusting our portfolio to achieve sustainable and improved profitability and to further expand our specialized capabilities. We delivered a full year 2019 Commercial Lines combined ratio of 92.1%, excluding catastrophes, and we grew almost 4%. Early indication is that Commercial Auto, one of our critical areas of focus for profit improvement initiatives last year, is performing slightly better than our expectations. We are not out of the woods yet, but we are seeing progress after considerable nonrenewals and double-digit rate increases that we achieved in 2019 and earlier. In our program business, we still have some additional work to do. We discontinued certain programs from the book in 2019. We will continue some of this work this year to ensure profitability in this business. Excluding targeted underwriting initiatives in Commercial Auto and programs, we generated overall Commercial Lines growth of 6.1%, with increasing growth momentum throughout the year, and our higher profit margin businesses such as Small Commercial and Professional Lines within Specialty. Additionally, our newer Specialty capabilities such as excess and surplus lines, cyber and financial institutions are gaining momentum. The pricing environment in Commercial Lines continues to be dynamic, but it did improve as the year progressed. Industry-wide rate decreases and benign loss trends in workers' compensation persisted, while double-digit rate increases in Commercial Auto continued throughout the year. We are observing firming trends in certain property and specialty lines in response to the large property losses and social inflation that many industry participants have been observing. Our Core Commercial pricing increased during the fourth quarter to 7.9%. The rate component continues to increase in a measured way. Also, as we have seen in prior quarters, exposure can and did drive some of the quarterly variability. Overall, we enjoy a strong market position in Commercial Lines. We are excited about the market dynamics, and we have confidence in our continued performance. As we look forward to 2020, and we believe we have a strong line of sight to mid-single-digit growth overall and double-digit growth in some of our most distinctive and profitable sectors. Our Personal Lines business had a very solid year. This business delivered a combined ratio of 91.6%, excluding catastrophes. While we experienced some pressure throughout the year from non-catastrophe weather and continuing prior year bodily injury trends, this business continued to achieve target returns. Our current year liability trends remain in line with our expectations, but we prudently increased our fourth quarter loss picks to reflect the increased legal environment and medical cost spilling over into the Personal Auto Line, which we have been observing in our prior year claims. Our Personal Lines business increased net premiums written by 5.7% for the year, driven by new business growth and rate increases. While the Personal Lines market remained very competitive throughout 2019, we continue to hold the line on pricing. We achieved 5% rate increases in this business in the fourth quarter, and will continue to balance pricing discipline with retention needs to produce optimal results. Today, account business represents approximately 85% of our portfolio, and we believe our new sales platform and account-centric product offerings will further fuel the growth of our whole account business. With continued price increases and strong support from our partners, we feel very good about 2020 prospects for Personal Lines and are targeting mid-single-digit growth. We begin the new year with healthy broad-based profitability, a strong book of business and outstanding agency relationships that will enable us to pursue market opportunities with more market insights. We are confident in our ability to navigate the dynamic loss environment effectively. As I look ahead, I am energized about our prospects. We believe the differentiated consultative relationship with our agent partners, combined with our broad portfolio, will continue to play to our advantage as we seek to deliver new, highly profitable business. Together with our partners, we are well positioned to capitalize on emerging opportunities and to continue to successfully build on our businesses. With that, I will turn the call over to Jeff.
