Rob Falzen
Vice Chairman at Prudential Financial
Thank you, Charlie.
I'll provide an overview of our financial results and business performance for our PGIM, U.S. and international businesses. I'll begin on Slide 6 with our financial results for the second quarter of 2024.
Our pretax adjusted operating income was $1.6 billion or $3.39 per share on an after-tax basis, up 10% from the year ago quarter, and 12.5% on a year-to-date basis. These results reflect the execution of our strategy to grow our market-leading businesses. Higher spread in fee income was the result of continued strong sales and the benefit of higher interest rates and equity markets. Additionally, expenses were lower and include a reduction in legal reserves.
Results for the current quarter also include a modest net favorable impact from our annual assumptions update and other refinements reflecting the benefit of our diversified business mix. Year-to-date, adjusted operating return on equity was 13.5% and has improved nearly 1.5 percentage points from the prior year. This reflects the strength of our businesses, the benefits from the deliberate actions we've taken to pivot to more capital-efficient products and operating efficiencies we've achieved that support growth.
Turning to the operating results from our businesses compared to the year ago quarter. PGIM, our Global Investment Manager had higher asset management fees, driven by favorable investment performance, contributions from the Deerpath Capital acquisition and equity market appreciation. Additionally, higher incentive and transaction fees resulted in an increase in other related revenues. This was partially offset by higher expenses to support business growth. Earnings growth in our U.S. businesses reflected higher spread income driven by business growth and the benefit of higher interest rates, more favorable underwriting results and lower expenses. In addition, a more favorable relative impact from our annual assumptions updates and other refinements was driven by a more favorable retirement strategies update, partially offset by a less favorable update in Individual Life.
This was partially offset by lower legacy traditional variable annuity fee income as we intentionally pivot to less market-sensitive products. Results of our international businesses included an unfavorable relative impact from our annual assumptions update and other refinements, less favorable underwriting results, primarily reflecting policyholder behavior, and lower spread income due to less favorable variable investment income. Results in the quarter also included higher joint venture earnings.
Turning to Slide 7. PGIM, our global investment manager, has diversified capabilities in both public and private asset classes across fixed income, equities and alternatives. PGIM's strong investment performance continues to improve, with 83% of assets under management exceeding their benchmarks over the past year. This has contributed favorably to strong long-term performance with 80% and over 90% of assets under management outperforming their benchmarks over the last 5- and 10-year periods, respectively.
PGIM's assets under management increased by 5% to $1.3 trillion from the year ago quarter, driven by market appreciation, investment performance and affiliated net flows. Third-party net outflows in the quarter totaled $9.5 billion. Institutional outflows of $8.9 billion were primarily in fixed income driven by 2 large clients. Retail outflows of $600 million were driven by sub-advised equity strategies and mutual funds and were partially offset by positive momentum in public fixed income. PGIM third-party flows are episodic due to large single client transactions. On a year-to-date basis, we generated $17.1 billion of inflows, reflecting the net benefit from large institutional pension clients.
As the investment engine of Prudential, PGIM's capabilities support the success and growth of our U.S. and international businesses in retirement, asset management and insurance. PGIM's asset origination capabilities, investment management expertise and access to institutional and other sources of private capital, including through the recently launched and reinsurer Prismec, our competitive advantage, helping our businesses bring enhanced solutions and create more value for our customers.
Our insurance and retirement businesses, in turn, provide a source of growth for PGIM through affiliated net flows as well as unique access to insurance liabilities. In addition, our diversified PGIM private alternatives platform, which has assets under management of approximately $240 billion, experienced strong private credit origination activity driven by our direct lending businesses, including from our recent acquisition of Deerpath Capital.
Turning to Slide 8. Our U.S. businesses produced diversified earnings from fees, net investment spread and underwriting income and benefit from our complementary mix of longevity and mortality businesses. We continue to focus on growing our market-leading businesses by transforming our capabilities to improve customer experiences and expanding our addressable market with new financial solutions leveraging the capabilities across Prudential. Retirement strategies generated strong sales of $7.5 billion in the second quarter across its institutional and individual lines of business. Institutional Retirement sales of $4 billion included U.S. funded pension risk transfer transactions of $1.4 billion and longevity risk transfer sales of $1.2 billion.
Year-to-date, Institutional Retirement has generated sales of $15 billion. Individual Retirement posted $3.5 billion in sales, its best quarter of sales in over a decade. Our product pivots have resulted in continued strong sales of FlexGuard and FlexGuard Income and fixed annuity sales have doubled from the prior year. Additionally, we continue to reduce market sensitivity by running off our legacy variable annuities. Group Insurance sales primarily occur in the first quarter of the year based on annual enrollments. On a year-to-date basis, sales increased 13% compared to the prior year, driven by growth in life, disability and supplemental health. We are executing our strategy of both product and client segmentation diversification while leveraging technology to increase operating efficiency and enhance customer experience.
These actions to improve profitability and performance resulted in a favorable benefit ratio of 81.1%. In Individual Life, sales increased 3% from the year ago quarter and 7% year-to-date. These increases include the benefit from our FlexGuard Life product, which reached its highest sales quarter since its launch in 2022 and from our pivot towards more capital-efficient products.
Turning to Slide 9. Our international businesses include our Japanese life insurance companies, where we have a differentiated multichannel distribution model as well as other businesses aimed at expanding our presence in targeted high-growth emerging markets. In Japan, we are focused on providing high-quality service and expanding our distribution and product offerings. Our needs-based approach and protection and retirement product focus continue to provide important value to our customers as we expand our product offerings to meet their evolving needs.
In emerging markets, we are focused on creating a selective portfolio of businesses and regions where customers' needs are growing where there are compelling opportunities to build market-leading businesses and where the Prudential Enterprise can add value. Sales in our international businesses were up 11% compared to the year ago quarter. Higher sales in Japan are benefiting from recent product launches as we expand our retirement and savings offerings. These new products are gaining traction with customers and represented 20% of the current quarter sales. In addition, emerging market sales were higher, driven by growth in Brazil as we continue to expand third-party distribution and benefit from the strong performance of our world-class life planners.
As we look ahead, we are well positioned across our businesses to be a global leader in expanding access to investing, insurance and retirement security. We continue to focus on investing in growth businesses and markets, delivering industry-leading customer experiences and creating the next generation of financial solutions to serve the diverse needs of a broad range of customers.
And with that, I'll now hand it over to Yanela.
