Robert Falzon
Vice Chairman at Prudential Financial
Thank you, Charlie. I'll provide an overview of our financial results and business performance for our PGIM US and international businesses. I'll begin on Slide six with our financial results for the third-quarter of 2023. Our pre-tax adjusted operating income was $1.6 billion or $3.44 per share on an after tax basis, up 45% from the year-ago quarter. These results reflect underlying business growth, including the benefits from our higher interest-rate environment, more favorable variable investment income and underwriting experience, partially offset by lower-fee income. Our GAAP net loss was $2.1 billion lower than our after tax adjusted operating income primarily driven by mark-to-market losses on interest-rate derivatives due to the higher rates.
Turning to the operating results from our businesses compared to the year ago quarter. PGIM our global investment manager had lower other-related revenues driven by lower agency and seed and co-investment earnings and higher expenses. Results of our US business has primarily reflected higher spread income including more favorable variable investment income and lower expenses, partially offset by lower-fee income. And the increase in earnings in our international businesses primarily reflected higher spread income. Turning to slide seven, PGIM our global active investment manager has diversified capabilities in both public and private asset classes across fixed-income, equities, and alternatives.
PGIMs long-term investment performance remains attractive with 80% or more of assets under management, outperforming their benchmarks over the last five and 10-year periods. In addition, our short-term performance continues to improve with 83% of assets exceeding their benchmarks over a one-year period. PGIM experienced third-party net outflows of $5.7 billion in the quarter. Institutional outflows were primarily driven by lower-than-normal fixed-income inflows and a large client outflow. Retail outflows were driven by sub-advised equity mandates. As the investment engine of Prudential the success and growth of PGIM and of our US and international insurance and retirement businesses, are mutually reinforcing. PGIMs asset origination capabilities and investment management expertise and access to institutional and other sources of private capital including through the recently launched reinsurer[phonetic] Prismic, 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, we continue to grow both organically and through acquisitions our private alternatives and credit business, which has assets of approximately $230 billion across private corporates in infrastructure credit, real-estate equity and debt, and secondary private-equity. Capital deployment across PGIMs private assets platform of $8 billion during the quarter benefited from robust private placement and direct lending originations.
Turning to slide eight, our US business has 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 drive towards a higher-value, higher-growth, and less market-sensitive mix of earnings, invest in our businesses to deliver best in class customer experiences and expanded our addressable market with new financial solutions, leveraging the capabilities across Prudential. Retirement strategies generated strong sales of $6.7 billion in the third-quarter across its institutional and individual lines of business. Our Institutional Retirement business has leading market capabilities, which helped to produce third-quarter sales of $4.7 billion including $2.5 billion of pension risk transfer transactions as well as strong, stable value sales.
Individual Retirement posted $2 billion in sales up 40% for the prior year quarter. Our product pivots[phonetic] have resulted in continued strong sales of FlexGuard and FlexGuard income, which represented about two-thirds of sales, and fixed annuities that accounted for approximately one-third of sales this quarter. Our individual life sales increased 24% from the year-ago quarter, reflecting our earlier product pivot strategy with variable life products, representing approximately 73% of sales in the quarter, including the benefit from our recently launched FlexGuard life product, and in Group Insurance we continue to execute on our strategy of product and client segment diversification while leveraging technology to increase operating efficiency and enhance the customer experience.
Our strong results this quarter included favorable group life underwriting experience, which resulted in a benefits ratio of 82.4%. Turning to slide nine, 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 product focus continued to provide important value to our customers as we expand our product offerings to meet their evolving needs. During the third-quarter, we launched a new US dollars indexed annuity product and Prudential Japan was ranked as the number-one Japanese life insurer in the Forbes World's Best life insurance companies this year.
We are proud to be recognized for the value we provide to our customers. In emerging markets, we are focused on creating a select portfolio of businesses in regions where our customer needs are growing, where there are compelling opportunities to build market-leading businesses and where the Prudential enterprise can add value. Our international business sales were up 19% compared to the year ago quarter. Life Planner sales were up 18%, driven by our second consecutive quarter of record sales in Brazil as well as higher sales in Japan. Gibraltar sales were up 20% primarily driven by growth in the bank channel.
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 turn it over to Ken.
