Thank you, operator. Good morning, and thank you for joining us for our quarterly conference call. We will begin today's call with prepared remarks from Jack Roche, our President and Chief Executive Officer; and Jeff Farber, our Chief Financial Officer. Available to answer your questions after our prepared remarks are Dick Lavey, President of Agency Markets; and Bryan Salvatore, President of Specialty Lines.
Before I turn the call over to Jack, let me note that our earnings press release, financial supplement and a complete slide presentation for today's call are available in the Investors section of our website at www.hanover.com. After the presentation, we will answer questions in the Q&A session. Our prepared remarks and responses to your questions today, other than statements of historical fact, include forward-looking statements as defined under the Private Securities Litigation Reform Act of 1995. These statements can relate to, among other things, our outlook and guidance for 2024 economic conditions and related effects, including economic and social inflation, potential recessionary impacts as well as other risks and uncertainties such as severe weather and catastrophes that could affect the company's performance and/or cause actual results to differ materially from those anticipated.
We caution you with respect to reliance with forward-looking statements, and in this respect, refer you to the forward-looking statements section in our press release, the presentation deck and our filings with the SEC. Today's discussion will also reference certain non-GAAP financial measures such as operating income and accident year loss and combined ratio, excluding catastrophes, among others. A reconciliation of these non-GAAP financial measures to the closest GAAP measure on historical basis can be found in the press release, the slide presentation or the financial supplement, which are posted on our website, as I mentioned earlier.
With those comments, I will turn the call over to Jack.
John "Jack" C. Roche: Thank you, Oksana. Good morning, everyone, and thank you all for joining us. We opened 2024 with an excellent first quarter, delivering robust earnings and effectively executing on our margin recapture and CAT mitigation plans. Consistent with our focus over the past several quarters, we remain disciplined and discerning in our growth as we continue to reposition our Personal Lines business and to improve earnings resiliency in our overall mix in order to drive strong, sustainable returns for our shareholders over the long term. On today's call, I will share my perspective on our results, as well as my thoughts on why we believe our company is well positioned to continue to deliver improving financial performance in 2024. Jeff will review our financial and operating results in more detail, and discuss our expectations for the second quarter and through year-end. Finally, we will open the line for questions.
After-tax operating income for the quarter was $112 million, or $3.08 per diluted share, generating an operating return on equity of 15%. We improved our ex-CAT combined ratio by more than 2 points in the quarter demonstrating the effectiveness of our margin recapture initiatives. As expected, overall growth was subdued in the quarter at 2.3% as we continue to prioritize profitability improvement actions. We expect to accelerate the pace of growth throughout 2024, and we expect to generate net written premium growth in the mid-single-digit range for the full year. We continue to effectively leverage our strong relationships with our best-in-class independent agent partners, helping them successfully navigate the dynamic marketplace and enabling us to build momentum in our target markets. Turning to our segment highlights.
In Specialty, we delivered another quarter of exceptional profitability, generating a combined ratio of 87.6%. Consistent with the outlook we provided on our year-end call, Specialty growth picked up from the low watermark in the fourth quarter. The market is very healthy and remains robust with exciting opportunities across Multiple Lines including Excess and Surplus Lines, Marine, Specialty Industrial Property, Healthcare and Surety. Other areas such as Professional and Executive Lines remain competitive, but we are seeing opportunities and premium growth picking up as well. In light of our robust profitability in this subsegment, we will continue to strike a prudent balance appropriately pricing risk while protecting our highly profitable book of business and pursuing quality new business opportunities.
At the same time, our Specialty top line results still reflect the impact of underwriting actions on specific underperforming programs within our Specialty P&C subsegment. The impact of these actions is expected to decrease as the year progresses. We expect Specialty net written premium growth in the upper single digits for the full year of 2024 as we further capitalize on our broad diversification and favorable market dynamics in most of our segments. In Marine, we anticipate significant growth in 2024 as we capitalize on opportunities across our diverse portfolio of inland marine products and sectors. In E&S, we expect the recent implementation of our new policy platform will enable us to capture even more market share beginning in the current quarter.
In Professional and Executive Lines, we see potential for increased growth in areas such as management liability and selected areas of our Professional Liability business. We're confident we can capitalize on these opportunities as they present themselves throughout the year, and that we will drive meaningful top line growth and further diversification across our overall business mix. Looking at Core Commercial, we are pleased with the segment's strong performance as we continue to provide our agents with a highly attractive portfolio of capabilities.
Our Core Commercial team maintained its focus on driving growth in Small Commercial while executing on margin improvement initiatives in Middle Market. Small Commercial grew by approximately 8% in the quarter, fueled by the continued success of our highly intuitive TAP sales platform. Our national rollout of this quote-to-issue platform for bot business is now complete. With that, we are actively working on adding the workers' compensation line of business to the platform, which will support our new business growth efforts in that area. In addition, we are expanding the use of APIs to further enhance our TAP sales reach by efficiently connecting to additional sources of business and adding targeted products to our specialized offerings.
In Middle Market, we continue to achieve better and more consistent earnings performance by aggressively nonrenewing bottom decile property business. We're also adjusting our new business appetite to reflect the changing environment, and ensuring that our pursuits are focused on high-quality accounts in targeted sectors and geographies. Additionally, we are making considerable progress against our IoT sensor enrollment program. While the program is targeted at most of our Property Lines, Middle Market remains in the epicenter of these actions given the higher limits profile. Across all of our business lines, we've deployed over 10,000 water and temperature sensors. That program has already resulted in numerous instances of loss prevention and mitigation. We believe we have achieved scale, meaning that operationally, we have enough sensors deployed where we can collect data and recognize trends, such as identifying geographic territories with higher risk profiles, several types of system failures or trends across certain industry sectors.
We believe this data will enable us to work even more effectively with our policyholders, providing guidance on how best to build resiliency. Overall, the Commercial P&C market remains rational, and continues to support needed price increases amid recent property loss trends and emerging industry concerns about casualty. For example, new business pricing in Small Commercial continues to accelerate and outpace loss trends.
In what has become an increasingly dynamic loss trend environment, we're often asked about our position relative to the social inflation challenges affecting the P&C industry. As a member of the American Property Casualty Insurance Association and other trade associations, we are actively engaged in promoting awareness and reforms to stem the cost of legal system abuse and in advocating for change. In addition, we believe our current liability profile will help us effectively navigate current social inflation trends.
On a relative basis, we have a low policy limit profile with over 93% of our liability policy limits at or below $1 million. We have secured and are maintaining low per-risk reinsurance retention, which attaches at $2.5 million, and we have avoided areas that attract a higher level of liability severity and are increasingly challenging to price adequately such as public D&O insurance and stand-alone excess umbrella policies. Over the last several years, we've also taken steps to lower our risk exposure in large metropolitan areas and in industries that are more susceptible to social inflation, reducing umbrella limits in certain lines in highly litigious jurisdictions and executing rate increases to stay on top of trend assumptions. We have approached this issue with a thoughtful and intentional strategy that we believe enables us to effectively manage the current liability environment.
Turning to Personal Lines. The business continues to demonstrate improved profitability and is performing largely on track relative to our expectations. Our loss ratio in both Auto and Home decreased compared with the first quarter of last year, in line with our assumptions. Personal Lines renewal price change was a robust 22.8% in the quarter. What's more? All targeted new business is subject to product changes, including an increase in all peril deductibles and the addition of wind and hail deductibles in certain geographies. These changes also are being rolled out with the renewals in targeted states. In addition, we continued to address geographic micro concentrations in the Midwest. As a result of our intense focus on profit improvement, as expected, net written premium growth in Personal Lines was flat year-over-year in the first quarter. We reduced our exposure in the Midwest in a deliberate and controlled manner during the quarter, resulting in a 4% decline in premiums in this region and an approximate 8% decline in policies in force.
Having the flexibility and the willingness to shed premiums to reposition our book will lead to improved profit margins in a higher, more resilient profit pool in the future. To that point, excluding Midwestern states, we have delivered growth of 4% with PIF down only 2% year-over-year. Primarily driven by lower new business, while retention remained relatively stable at over 84%. This said, in select geographies, we are already pivoting to a more aggressive new business stance where we have hit our profitability milestones on a written basis and where we are already comfortable with diversification positioning.
Overall, the Personal Lines market remains robust. We expect premium growth to accelerate from this point forward and pricing to remain firm in 2024. In the Midwest, we are seeing others follow our lead, implementing higher deductibles and introducing other product changes to offset loss trends. Our Personal Line's account orientation is unique in the independent agency channel, with about 88% of our business representing a whole account. In our view, that orientation creates a preferred customer base that is both more protection minded and far less price elastic which we believe will position us for continued success.
As we work to institute increased pricing deductibles and to adjust terms and conditions, our strong independent agency relationships are once again proving to be critical. Just a few weeks ago, we met with over 120 of our largest, most successful agents at our Annual President's Club Conference. We held a number of executive meetings focused on how we can best support our agents in the current dynamic market environment and grow our business together. We believe our independent partner agents fully recognize the critical role they play in our efforts to advance customer adoption of risk prevention and mitigation tools as well as in garnering customer support for the needed pricing increases we are implementing. We walked away from this annual event with more confidence than ever in the strength of our distribution platform and the commitment of our agent partners.
In summary, our excellent performance in Q1 underscores the strength, diversification and resilience of our business. We already have begun to see the positive effects of our underwriting actions, catastrophe management initiatives and other proactive steps to enhance profitability across our businesses. We look forward through year-end and beyond with a tremendous sense of optimism. Confident in our ability to deliver increasingly stronger results to execute on our strategic priorities and to deliver value for our shareholders, agent partners and customers. With that, I'll turn the call over to Jeff.
