Thanks very much, and good morning. Today's remarks may include forward-looking statements which are subject to risks and uncertainties. These statements are not guarantees of future performance or events and are based on management's current expectations. AIG's filings with the SEC provide details on important factors that could cause actual results or events to differ materially. Except as required by applicable securities laws, AIG is under no obligation to update any forward-looking statements if circumstances or management's estimates or opinions should change. Today's remarks may also refer to non-GAAP financial measures. The reconciliation of such measures to the most comparable GAAP figures is included in our earnings release, financial supplement, and earnings presentation, all of which are available on our website at aig.com.
Following the deconsolidation of Corebridge Financial on June 9th, 2024, the historical results of Corebridge for all periods presented are reflected in AIG's consolidated financial statements as discontinued operations in accordance with U.S. GAAP. Finally, today's remarks related to net premiums written are presented on a comparable basis, which reflects year-over-year comparison on a constant dollar basis and adjusted for the sale of the global personal travel and assistance business as applicable. We believe this presentation provides the most useful view of our results and the go-forward business in light of the substantial changes to the portfolio since 2023. Please refer to page 27 of the earnings presentation for reconciliations of such metrics reported on a comparable basis. With that, I'd now like to turn the call over to our Chairman and CEO, Peter Zaffino.
Good morning, everyone. Thank you for joining us today to review our third quarter 2025 financial results. Following my remarks, Keith will provide more detail, and then Jon Hancock and Don Bailey will join us for the Q&A portion of our call. This has been an exceptional third quarter for AIG, and an incredibly busy one. We achieved tremendous EPS and ROE results as we continued to execute on our strategy to deliver sustainable, profitable growth. Last week, we had several announcements involving Convex Group, Onex Corporation, and Everest Group. The key takeaway is that they are all expected to be earnings, EPS, and ROE accretive in the first year post-closing. We believe each will accelerate AIG's progress and create long-term value for our company and our stakeholders. This was made possible due to our strong balance sheet, prudent capital management, and financial flexibility.
It's simply been an outstanding quarter, and I'm very proud of our colleagues for all they've accomplished together. For our call this morning, I will share a high-level overview of our third quarter results, provide a perspective on our strategic investments and renewal rights acquisition, give a brief update on our GenAI initiatives, and conclude with an overview of our capital management strategy and the progress against our Investor Day financial objectives. In the third quarter, we delivered adjusted after-tax income per diluted share of $2.20, which is an increase of 77% year-over-year. Adjusted after-tax income for the quarter is $1.2 billion, an increase of 52% year-over-year, driven by our general insurance business. Underwriting income was $793 million, an increase of 81% year-over-year. Net investment income on an adjusted pre-tax basis was $1 billion, an increase of 15% year-over-year. The accident year combined ratio, as adjusted, was 88.3%.
In line with the prior year quarter and our 16th consecutive quarter with a sub-90% result. The calendar year combined ratio was 86.8%, an improvement of 580 basis points from the prior year quarter. Now, let me provide some detail on our performance across the three business segments. Let's start with North America commercial insurance. Net premiums written were flat year-over-year. It's worth noting, which we mentioned on our third quarter 2024 earnings call, that we had a closeout transaction in our casualty portfolio that benefited overall growth in the prior year quarter. Adjusting for this, net premiums written would have increased 3%. This growth was driven in targeted areas, notably programs, which increased 27%. Western World, which increased 11%, and Excess Casualty, which increased 8%. This was partially offset by Retail Property, which declined 10%, and Lexington Property, which declined 8%, where rate pressure has been most prevalent.
We spoke about property quite a bit last quarter. Keith will go into more detail in his prepared remarks, and we can discuss further in Q&A. Despite pressure on rates, the accident year and calendar year combined ratios remain exceptional for the property portfolio. North America new business was very strong. While Lexington's new business was flat year-over-year, it was the biggest nominal contributor to new business in North America. Its submission count was up 18% year-over-year, following significant increases over the last two years of 34% in the third quarter of 2024 and 47% in the third quarter of 2023. Financial Lines new business was up 16%, led by M&A. Turning now to international commercial insurance, net premiums written increased 1% year-over-year, driven by Marine, which increased 11%, and property, which increased 6%. This was partially offset by Financial Lines, which declined 6%.
International commercial had an outstanding quarter for new business, led by Specialty, which increased 17% year-over-year, driven by Marine, which increased 35%, and energy, which increased 30%. Property increased 24%, and Financial Lines increased 12%, driven by higher M&A activity in the quarter. In global personal, net premiums written decreased 4%, driven by the high net worth quota share reinsurance treaty that we entered into at 01/01/2025. While this continues to improve profitability in the portfolio for 2025, it negatively impacted global personal net premiums written. We expect to see this premium trend reverse in 2026. Overall, it was a great quarter of performance for AIG, and it positions us for a strong finish to 2025. Last week was a momentous one for AIG. We announced strategic investments with Convex Group, Onex Corporation, and a transaction with Everest Group.
These will strengthen AIG's long-term value and strategic positioning, and we expect they will be earnings, EPS, and ROE accretive one year after closing, aligned with the objectives we outlined at Investor Day. This is in line with my previous comments that we would look for compelling opportunities to deploy capital in ways that would be accretive to our financial metrics and to further build our business. As a point of reference, over the last three years, we've returned a total of $19 billion of capital to shareholders through approximately $16 billion of share repurchases and $3 billion of common stock dividends. In addition, we reduced debt by $4.5 billion. We now believe we have a capital structure that's optimal for our current business. When you look at the global insurance industry, there's a scarcity of high-quality insurance assets.
We've been fortunate to secure a long-term investment in one of the very best global specialty and reinsurance companies, Convex Group. I know Convex Group extremely well. I have known and traded with its Chairman, Stephen Catlin, and Chief Executive Officer, Paul Brand, for over 20 years. I have deep respect for their expertise, leadership, and the culture they have built. With Convex, we will gain access to a world-class underwriting platform for complex specialty risks with a strong underwriting culture, a growing premium base, and a proven track record of outstanding performance and profitability. Stephen and Paul have earned a reputation for building exceptional underwriting teams, and this is reflected in the company's impressive performance. Convex was founded in 2019 and has consistently delivered very strong underwriting and financial results.
With a combined ratio in the high 80%, no historical reserve issues, no legacy technology debt, a highly scalable platform, and significant potential for continued growth. Over the last three years, Convex delivered a 25% compound annual growth in gross premiums written and an 18% average return on equity, demonstrating the strength of their business model and ability to produce sustainable long-term value. Last week, AIG agreed to acquire 35% equity interest in Convex, while Onex Corporation took a 63% ownership position to be held directly on their balance sheet rather than through one of their investment funds. In addition, to benefiting from the ongoing success of Convex through an equity investment, AIG will also participate in Convex's portfolio through a whole-account quota share, which enables us to share directly in Convex's underwriting growth and expected profitability over the short, medium, and long term.
The agreement gives AIG the opportunity to participate in 7.5% of Convex's portfolio on January 1, 2026, and that will progressively increase to 10% by 2027 and 12.5% by 2028. The Convex transaction is expected to close in the first half of 2026. As part of our discussions with Convex management, we were presented with an opportunity to acquire a minority ownership stake in Onex Corporation. With headquarters in Toronto, Onex is a leading private equity and credit investor with $56 billion of assets under management and 120 investment professionals based across Canada, the U.S., and the U.K. Our strategic relationship with Onex presents a unique opportunity for AIG to partner through an equity investment with a global asset manager with a strong record of investing in the insurance sector.
Onex has made a number of notable and highly successful strategic investments in specialized insurance platforms, including Convex, Ryan Specialty, OneDigital, and USI. Let me unpack the details of our investment in Onex. We've agreed to acquire a 9.9% equity interest. Additionally, in line with our investment guidelines, we've committed to invest $2 billion over three years across Onex's broad asset management platform, which will provide us with a broader view of opportunities and deepen our market position within the global insurance industry. Keith will provide more detail in his remarks, but just to give you a brief overview, these investments have the potential to deliver a higher yield for AIG, supporting earnings growth and enhancing return on equity. We've evaluated investment opportunities in several fund managers in the alternative asset space over time and believe this is the right opportunity for us.
Post-transaction, over 40% of Onex's total balance sheet net asset value is expected to relate to its majority ownership of Convex. The Onex transaction is also expected to close in the first half of 2026. Finally, last week, we also announced our acquisition of the renewal rights for the majority of Everest's core retail commercial property and casualty portfolios, representing approximately $2 billion of gross premiums written across multiple geographies. We greatly appreciate Everest's willingness to engage in a bilateral discussion to structure a transaction that further strengthens both companies and our mutual business relationship. We purchased the renewal rights for approximately $300 million, with a potential downward adjustment of up to $70 million, depending on how much of the portfolio is renewed with AIG.
Under the terms of the transaction, AIG did not take any of the in-force portfolio or unearned premium for policies with effective dates prior to December 31st, 2025, and we will not assume any liabilities for any of the policies previously underwritten by Everest. Everest employees will remain with Everest Group, though in certain geographies and businesses, we will work with Everest to offer opportunities to select staff members. We have also entered into a transition service agreement with defined service levels to ensure continuity for clients and brokers as the portfolio is transferred to AIG. In terms of the portfolio, it is well-diversified across geographies and classes of business. The largest portion of the in-force eligible gross premiums written is in the United States at $1.3 billion, followed by Europe at $400 million, the U.K. at $150 million, Australia at $80 million, and Singapore at $70 million.
Thank you, Peter, and good morning. I'm going to expand on the financial highlights for the quarter.
Adjusted pre-tax income, or APTI, was $1.6 billion, an increase of 51% from the prior year quarter. This was driven by strong results from the business and execution of our investment portfolio strategy. General insurance gross premiums written were $8.7 billion in the third quarter, an increase of 1% from the prior year. Net premiums written were $6.2 billion, a decrease of 1%. As Peter discussed, we had strong new business and retention in the quarter. I will comment on the rate environment later in my remarks. For the third quarter, general insurance accident year combined ratio as adjusted was 88.3%, which is the same as the prior year quarter. Accident year loss ratio was 57.4%, a 100 basis point increase year-over-year.
This was primarily driven by the reapportionment of unallocated loss adjustment expenses, and we had more favorable actual versus expected recognized in specialty in the prior year quarter. This was partially offset by underlying improvement in global personal. Our general insurance expense ratio was 30.9%, a 100 basis point improvement year-over-year. For the first nine months of 2025, the general insurance expense ratio was 30.8% compared to 31.7% for the prior year period. This demonstrates our operational excellence and discipline in driving efficiencies as we have shifted expenses from other operations into general insurance while investing in underwriting capabilities, technology, and infrastructure. For context, since 2023, the business has absorbed an additional $400 million of parent costs that used to be in other operations. We expect to be at $350 million of other operations expense for full year 2025.
Our teams have done a fantastic job of managing expenses, and we expect to achieve our target of below 30% by 2027. Total catastrophe losses for the quarter totaled $100 million, or 1.6 loss ratio points, an excellent result. Prior year development net of reinsurance was $205 million favorable, which included $174 million of favorable loss reserve development and $31 million of ADC amortization. North America commercial was favorable $139 million across our property, casualty, and Financial Lines. International commercial was also favorable by $47 million, primarily driven by shorter tail lines and global specialty, partially offset by movements on select longer tail lines, largely driven by auto trends and adverse development on pre-2018 general liability reserves. Global personal was $19 million favorable. These results include a reapportionment of the remainder of our uncertainty provision across all three segments, predominantly into longer tail lines.
Similar to last quarter, this was not related to any observable deterioration in our book. We continue to build on our strong balance sheet and have a high level of confidence in our reserve position, supported by the favorable actual versus expected trends we continue to observe. Overall, general insurance calendar year combined ratio was outstanding at 86.8%. A 580 basis point improvement compared to the prior year quarter. Now moving to the segments. North America commercial accident year combined ratio as adjusted was 85.4%, an increase of 30 basis points over the prior year quarter. The accident year loss ratio of 62.1% was up 30 basis points, owing to changes in business mix as we continue to earn in casualty business and reduce certain property lines. A partial one-time offset due to last year's casualty closeout transaction.
The expense ratio was flat to last year at 23.3%, including a 60 basis point improvement in the acquisition ratio, offset by a higher GOE ratio due to the movement of expenses into the business from other operations. The quarter included 310 basis points of catastrophe losses and 590 basis points of favorable prior year development. North America commercial calendar year combined ratio was 82.6%, an improvement of almost 13 percentage points. Turning to international commercial, the accident year combined ratio as adjusted was 86.0%, an increase of 260 basis points. The accident year loss ratio was 54.4%, a 170 basis point increase year-over-year, largely from reapportionment of unallocated loss adjustment expenses and less favorability in specialty, as we mentioned earlier. The expense ratio rose 90 basis points to 31.6%, driven by movement of expenses from other operations.
This quarter included 80 basis points of catastrophe losses and 190 basis points of favorable prior year development. The international commercial calendar year combined ratio was 84.9%. This is the 10th consecutive quarter of a sub-90% combined ratio for the international commercial segment, which speaks to the quality of our portfolio. Turning to global personal, the accident year combined ratio as adjusted was 95.5%, a 330 basis point improvement year-over-year, adjusting for the divested travel business. The accident year loss ratio improved 90 basis points to 55.3%, driven by underwriting actions leading to stronger underlying profitability and lower reinsurance costs. The expense ratio improved 240 basis points to 40.2%, driven by the acquisition ratio, which is benefiting from a combination of improved commission terms in the U.S. high net worth business, operational efficiencies, and changes in business mix.
This quarter included 80 basis points of catastrophe losses and 110 basis points of favorable prior year development. The global personal calendar year combined ratio was 95.2%, an improvement of 520 basis points year-over-year. We continue to make steady progress, increasing the profitability of global personal as outlined at Investor Day. Moving to rates. In North America, market conditions for pricing have remained largely stable. Excluding the property business, our North America commercial renewal pricing increase was 5%. In North America casualty, the overall pricing environment remains favorable, with retail Excess Casualty up 13% and Lexington Casualty up 14%. In North America Financial Lines, pricing was down 2% in line with the second quarter. The pricing reductions have moderated, and we continue to focus on our differentiated offering and leadership position.
North America property continued to see pricing pressure, with the overall portfolio showing improvement from last quarter, largely as a result of mix. The property market rate environment remains challenging, and we continue to have strong profitability across our retail and wholesale business while prioritizing underwriting discipline. International commercial overall pricing was down 2%. Across our international property portfolios, pricing was up 4%, driven by 16% rate increases in Japan. Global specialty pricing was down 4%. Since 2018, the cumulative rate increases on our global specialty book have been very strong, with over 100% increase in energy where rates are currently challenged. Overall pricing remains above our technical view. Talbot and Financial Lines pricing was also down 4%. AIG's well-diversified global portfolio allows us to manage across geography and products, prioritizing lines of business that offer the best risk-adjusted returns. Moving to other operations.
Third quarter adjusted pre-tax loss was $116 million versus the prior year quarter of $135 million. This reflects a significant reduction in general operating expense and lower interest expense, partially offset by lower net investment income as we reduced our corporate financial stake. Total GOE across both general insurance and other operations was $866 million in the third quarter, up 1% from the prior year adjusting for travel. For the nine months of 2025, total GOE was $2.5 billion, down 2% year-over-year, while net premiums earned grew by 5%. This is an impressive outcome, reflecting positive operating leverage, allowing us to create bandwidth for future investments. The third quarter net investment income on an APTI basis reached $1 billion, an increase of 15% year-over-year. General insurance net investment income was $945 million, growing 22% year-over-year.
The increase was driven by fixed maturity securities owing to the optimization of our lower yielding portfolios, asset growth, and higher reinvestment yields, in addition to improved alternative returns. During the third quarter, the average new money yield on the fixed maturity and loan portfolio was roughly 95 basis points higher than sales and maturities. The annualized yield was 4.58%, a 69 basis point improvement over the prior year. Alternative investment income was also very strong this quarter at $137 million, yielding 13.6%, compared to $43 million and 4.3% in the prior year quarter. Our well-diversified private equity portfolio contributed to this excellent performance. At Investor Day, we talked about opportunities to optimize our core portfolio, particularly in some lower yielding geographies, as well as prudently increasing the allocation to private credit when we see attractive premiums over public credit.
As part of the reshaping of our portfolio, we have reduced hedge funds and global real estate by $1.5 billion collectively since 2021. We largely have completed the rebalancing of public credit across multiple geographies. Yields are now more consistent with where we believe we should operate, and we expect net investment income growth going forward to be more in line with asset growth, given the current and projected level of global interest rates. Over the next few years, we will opportunistically allocate funds to private credit, which currently stands at $6.4 billion at the end of the third quarter, or 8% of the GI portfolio. Overall allocations to private credit have not materially changed since Investor Day. As stated at Investor Day, we intend to take that up to 12%-15% over time, subject to market conditions. Private credit is a large and diverse asset class.
Thanks, Keith. Michelle, we're ready for questions.
