Selective closed 2025 with a strong fourth quarter, posting a 93.8% GAAP combined ratio (a 4.7-point improvement year-over-year on no net prior-year reserve development), fully diluted EPS of $2.52 (up 66%), and non-GAAP operating EPS of $2.57 (up 59%), for an 18.7% operating ROE. For the full year the company delivered a 14.2% operating ROE, grew book value per share 18%, and returned $182 million to shareholders through dividends and buybacks, though the full-year combined ratio of 97.2 landed just outside the original 96%-97% guidance after roughly $190 million of commercial-auto reserve strengthening during the year. Management renewed its property-catastrophe reinsurance at meaningful risk-adjusted price decreases, held the $100 million retention, and AM Best affirmed the A+ financial-strength rating. For 2026 Selective guided to a 96.5%-97.5% GAAP combined ratio (six points of catastrophes), after-tax net investment income of $465 million (up 10%), and an implied operating ROE in the 14% range as it marks its 100th anniversary.
Good morning. Thank you for joining Selective's fourth quarter and full year 2025 earnings conference call. Yesterday, we posted our earnings press release, financial supplement, and investor presentation on selective.com's investor section. A replay of the webcast will be available there shortly after this call. John Marchioni, our Chairman of the Board, President, and Chief Executive Officer, and Patrick Brennan, Executive Vice President and Chief Financial Officer, will discuss results and take your questions. We will reference non-GAAP measures that insurance and investment professionals use to evaluate operational and financial performance. These non-GAAP measures include operating income, operating return on common equity, and adjusted book value per common share. The financial supplements on our website include GAAP reconciliations to any referenced non-GAAP financial measures. We will also make statements and projections about our future performance.

These statements are subject to risks and uncertainties that we disclose in our annual, quarterly, and current reports filed with the SEC. We undertake no obligation to update or revise any forward-looking statements. Now, I'll turn the call over to John.
Thanks, Brad, and good morning. We are well-positioned to build on recent momentum. In 2025, we delivered an ROE of 14.4% and an operating ROE of 14.2%. This exceeds our 10-year average operating ROE of 12.1% and our 5-year average of 12.5%. We are proud of our long-term track record and are taking clear steps to drive future margin improvement. In 2025, we grew book value per share by 18% and returned $182 million to shareholders through our common dividends and share repurchases at attractive valuations. With our strong capital position, we can deploy capital in several ways that are accretive to long-term value, including continued investments to grow and diversify our business, along with opportunistic share repurchases. We have a strong foundation with opportunities to drive improvement across our organization.
We delivered a 93.8% combined ratio in the quarter, reducing our full-year combined ratio to 97.2, just outside the 96%-97% guidance we provided at the beginning of the year, and at the low end of the 97%-98% guidance provided last quarter. Net premiums written growth was 5% for the year as we executed deliberate actions to improve underwriting profitability. This remains our primary focus. However, we are also executing strategies to support future growth opportunities, including expanding our geographic footprint and broadening E&S distribution capabilities with retail access. We believe we have the capabilities and strategy to further diversify our premium and outpace industry growth in coming years. In the fourth quarter, favorable workers' compensation development offset unfavorable prior year emergence in the commercial and personal auto lines and E&S casualty.
There are also several smaller adjustments across multiple lines of business, including umbrella, which was driven by auto. In 2024 and 2025, we took meaningful actions to strengthen reserves. Our picks for older accident years have held up well, and our actions have been increasingly weighted to more recent accident years. We are comfortable with our overall carried reserve position. We firmly believe our disciplined approach responds promptly and appropriately to emerging trends and ensures pricing targets keep pace with an evolving external environment, even though it can create short-term volatility. We will stick to our process, continuing to assess emerging information, considering risk factors, and booking our best reserve estimates each quarter. We expected 2025 accident year margins to improve for commercial automobile, as we have earned double-digit rate increases over multiple years that exceeded our assumed loss trend of roughly 8%.
As 2025 progressed, we ultimately increased commercial auto casualty loss costs by nearly 6 points. We also increased our expected severity trend for commercial auto liability to approximately 10%. This assumption is reflected in our book results and incorporated into our 2026 guidance. In total, we strengthened commercial auto reserves by approximately $190 million in 2025. The majority is attributable to the 2024 and 2025 accident years, with 2025 representing the largest share. We are addressing commercial auto with both underwriting and claims actions. For example, we've implemented tighter underwriting guidelines for fleet exposures, supported by state-specific tactics, and focused our commercial auto telematics rollout in specific segments and states. In general liability, we've discussed our actions to manage limits in challenging jurisdictions and trim underperforming classes.
We are also prioritizing new business in better-performing segments and have strengthened new business pricing. Standard Commercial Lines is our largest segment and our earnings engine. We have the sophisticated pricing and risk selection tools in the hands of our talented underwriters that are necessary for taking granular action across the portfolio. We are improving mix by achieving stronger rate and retention differentiation based on expected profitability, while continuing to focus on overall rate adequacy. This is not new, but we expect the amount of differentiation to increase. We are leveraging our tools, granular insights, and differentiated operating model to drive higher renewal retention on our best-performing business, and meaningfully lower retention on our poorer-performing business through appropriate rating actions. While overall rate increases could moderate in the short term, we expect these mix improvement actions will deliver improved profitability.
Our guidance reflects the benefits we expect in 2026 from the various actions we have taken, and our multiyear plan points to continued margin improvement in 2027. Now I'll turn the call over to Patrick.
Thanks, John, and good morning, everyone. For the quarter, fully diluted EPS was $2.52, up 66% from a year ago. Non-GAAP operating EPS was $2.57, up 59%. Our return on equity was 18.3%, and our non-GAAP operating return on equity was 18.7%, reflecting continued strong investment performance. The GAAP combined ratio was 93.8, a 4.7-point improvement from fourth quarter of 2024, mainly because this quarter had no net prior year reserve development. For the quarter, the overall underlying combined ratio was 92.1, a point and a half higher than the 90.6 a year ago. The increase is attributable to the reserving actions we took to address the 2025 accident year, primarily in Commercial Auto.
This quarter's Standard Commercial Lines combined ratio was 92.9%, which included 1.6 points of favorable prior year casualty development and 3.2 points of higher current year casualty loss costs. As John noted, the current environment demands strong underwriting and pricing discipline. Standard Commercial Lines premium growth in the quarter was 5%, driven by renewal pure price increase of 7.5%, or 8.5% excluding Workers' Compensation. General Liability pricing increased by 9.8%, and Commercial Auto pricing increased by 8.6%. While there was some deceleration in Commercial Auto pricing for physical damage, liability price increases continued to exceed 10%. For Property, renewal premium change was 12.2%, including 4 points of exposure growth.
Retention for the quarter was 82%, stable with recent periods, but down 3 points from a year ago. Excess and Surplus Lines premium grew 4% this quarter, with average renewal pure price increases of 7.8%. We continue to push higher rate levels in E&S casualty based on our view of general liability loss trends. The E&S combined ratio for the quarter was 93.1%, and a very strong 87.8% for the year. Turning to personal lines, the combined ratio for the quarter was 103%, up 91.7% in the fourth quarter of 2024. There were two reasons for the deterioration. Catastrophe losses, which were 6.2 points higher this quarter, and current year casualty loss costs, which increased by 8.1 points.
Current year adjustments were driven by New Jersey Personal Auto. For the year, the Personal Lines combined ratio was 100.6%, improved from 109.3% in 2024. Results are even more favorable for the portfolio outside of New Jersey, and we are positioned for profitable growth in those states. For the quarter, Personal Lines net premiums written declined 8%, with target business up 5%. Nearly all our new business was in our target mass affluent market. Renewal pure price for the quarter was 15.1%. Across all our segments, the combined ratio was 97.2% in 2025, a significant improvement from 2024's 103%, primarily because of lower prior year casualty reserve development and catastrophe losses. Last quarter, we discussed our third-party claims review, which was ongoing at that time.
The review is now complete, and the findings were consistent with what we had previously discussed. Turning to investments, fourth quarter after-tax net investment income was $114 million, up 17% from a year ago, and generated 13.6 points of return on equity. Our investment portfolio remains conservatively positioned, and our investment strategy is consistent, with average credit quality of A+ and a duration of 4.1 years. We expect the portfolio's strong embedded book yield to continue to provide a durable source of future investment income, even if interest rates decline. We successfully renewed our property catastrophe reinsurance program, effective January first. Our retention remains $100 million, and we increased our coverage exhaustion point to $1.5 billion from $1.4 billion.
Property market conditions are attractive, and we completed the renewal with meaningful risk-adjusted pricing decreases and improved terms and conditions. We continue to supplement our main tower with a personal lines-only buy down layer. Our peak peril, U.S. hurricane, is well within our risk tolerance at 5% of GAAP equity for a 1 in 250-year net probable maximum loss. Our capital management strategies continue to prioritize profitable growth within our insurance business and aim to return 20%-25% of our earnings to shareholders through dividends. We also expect to opportunistically repurchase shares. These actions reflect our commitment to delivering long-term value to shareholders. During the quarter, we repurchased $30 million of common stock, bringing our total repurchases for the year to $86 million. We believe these repurchases are completed at attractive valuations.
At year-end, $170 million remained on our authorization. Book value per share increased 18%, and we reported $3.6 billion of both GAAP equity and statutory surplus. We ended the year with a strong capital position, and we are proud that AM Best recently affirmed our A+ financial strength rating. For 2026, we expect a GAAP combined ratio between 96.5% and 97.5%. Our guidance assumes six points of catastrophe losses. We do not make assumptions about future reserve development as we book our best estimate each quarter. We expect after-tax net investment income to be $465 million. This is up 10% from 2025, reflecting growth in our invested assets. Our guidance includes an overall effective tax rate of approximately 21.5%.
Weighted average shares are estimated to be approximately 61 million on a fully diluted basis, without assumptions about share repurchases under our existing authorization. As a reminder, our first quarter underlying combined ratios tend to be higher than the rest of the year due to normal seasonality. For financial modeling purposes, this has historically been most relevant to non-catastrophe property losses. Corporate expenses also tend to be higher in the first quarter due to holding company expenses related to stock compensation. Now, I'll turn the call back to John.
Thanks, Patrick. Our 2026 guidance implies an underlying combined ratio in the 90.5%-91.5% range, compared to the 91.8 we reported in 2025. Our guidance does not provide segment-level combined ratios. However, directionally, we expect underlying combined ratio improvement in Personal Lines and Commercial Lines, and continuing strong performance in E&S. Our 2026 guidance considers reserve actions for recent accident years and embeds an overall expected loss trend of approximately 7.5%, up from the 7% we assumed a year ago. Our loss trend assumptions are 3.5% for Property and 9% for casualty. The casualty trend would be closer to 10%, excluding Workers' Compensation.
We expect our 2026 expense ratio to increase by about 0.5 point as we make strategic technology investments to support scale, enhance decision-making, and improve operational efficiency. With expected strong investment income, our 2026 guidance implies an operating ROE in the 14% range. Before turning to your questions, I want to remind everyone that Selective is celebrating its 100th anniversary in 2026. We are proud of our history, the work of our employees, and the value we deliver to our policyholders, distribution partners, and shareholders. We are excited to build on our legacy of success.
To drive this, we remain focused on a set of key priorities across the company, including relentlessly improving on the fundamentals across risk selection, individual policy pricing, and claim outcomes, diversifying revenue and income within and across our three insurance segments, and further leveraging our use of data, analytics, and technology, including artificial intelligence, to drive operational efficiency and improved underwriting and claim outcomes. I'll now ask the operator to begin our question-and-answer session.
