John D. McCallion
Executive Vice President and Chief Financial Officer at MetLife
Thank you, Michel, and good morning. I'll start with the 2Q 2024 supplemental slides, which provide highlights of our financial performance and an update on our liquidity and capital position. Starting on page three, we provide a comparison of net income to adjusted earnings in the second quarter. We had net derivative losses, primarily due to the strengthening of the US dollar versus the yen, as well as higher interest rates.
That said, derivative losses were partially offset by market risk benefit, or MRB, remeasurement gains due to the higher interest rates and stronger equity markets. Net investment losses were mainly the result of normal trading activity for fixed maturity securities in a higher rate environment. Overall, the investment portfolio remains well positioned, credit losses continue to be modest, and our hedging program performed as expected.
On page four, you can see the second quarter year-over-year comparison of adjusted earnings by segment, which should not have any notable items in either period. Adjusted earnings were $1.6 billion, up 9% and 11% on a constant currency basis. Favorable underwriting, volume growth and higher variable investment income drove the year-over-year increase. This was partially offset by lower recurring interest margins. Adjusted earnings per share were $2.28, up 18% and up 20% on a constant currency basis.
Moving to the businesses, group benefits adjusted earnings were $533 million, up 43% year-over-year, primarily due to favorable underwriting margins. The group life mortality ratio was a record low of 79.1%, well below our annual target range of 84% to 89%, driven by favorable experience across all coverages. The strong group life results mirrored the notably low number of US deaths between the ages of 25 and 64 in April and May, according to CDC data.
Regarding non-medical health, the interest-adjusted benefit ratio was 70.8% in the quarter, toward the bottom end of our annual target range of 69% to 74%, and below the prior year quarter of 73.7%. Favorable disability results benefited from a reserve adjustment of approximately $30 million after tax. Turning to the top line, group benefits adjusted PFOs were up 3% year-over-year. Taking participating contracts into account, which dampened growth by roughly 200 basis points, the underlying PFOs were up approximately 5% year-over-year, and at the midpoint of our 2024 target growth range of 4% to 6%.
Group benefits 2Q 2024 year-to-date sales were up 11%, driven by strong growth across most products, including our suite of voluntary products. RIS adjusted earnings were $410 million, down 2% versus the prior year.. Lower recurring interest margins were partially offset by higher variable investment income and strong volume growth. RIS investment spreads were 121 basis points, down six basis points sequentially, mainly due to the expiration of interest rate caps in the second quarter of 2024.
We anticipate that spreads will remain between our annual target range of 115 and 140 basis points in the third quarter. Although we foresee an increase in variable investment income, it will likely be balanced out by reduced earnings from the expiration of the interest rate caps. RIS adjusted PFOs, excluding pension risk transfers, were up 4% year-over-year, primarily driven by strong sales of institutional income annuities as well as growth in UK longevity reinsurance. With regards to PRT, we had approximately $3.5 billion in deals in the second quarter and continue to see an active market.
Moving to Asia. Adjusted earnings were $449 million, up 4% and 8% on a constant currency basis, primarily due to favorable underwriting margins and higher variable investment income. For Asia's key growth metrics, general account assets under management on an amortized cost basis were up 5% year-over-year on a constant currency basis. Sales were up 4% on a constant currency basis compared to a strong prior year quarter.
While Japan sales were down 19% year-over-year on a constant currency basis, primarily due to the impact of yen volatility on foreign currency products. This was more than offset by strong sales growth of 60% in the rest of the region, including a large group case in Australia. Latin America adjusted earnings were $226 million, up 3% on reported basis and 8% on a reported basis, primarily driven by solid volume growth across the region and favorable underwriting.
This was partially offset by lower Chilean encaje returns of a negative 2.4% in Q2 of 2024 compared to a positive 1.4% in Q2 of the prior year. Latin America's top line continues to perform well as adjusted PFOs were up 9% or 12% on a constant currency basis, driven by growth across the region. EMEA adjusted earnings were $77million, up 10% and 20% on a constant currency basis, driven by volume growth and higher recurring interest margins. This was partially offset by less favorable expense margins year-over-year.
EMEA adjusted PFOs were up 7% and 12% on a constant currency basis, and sales were up 31% on a constant currency basis, reflecting strong growth in Turkey, the Gulf and the U.K. MetLife Holdings adjusted earnings were $153 million, down 27% versus the prior year quarter. The primary driver was the foregone earnings due to the reinsurance transaction that closed in November. Corporate and Other adjusted loss was $220 million versus an adjusted loss of $228 million in the prior year.
The company's effective tax rate on adjusted earnings in the quarter was approximately 24% and within our 2024 guidance range of 24% to 26%. On page five, this chart reflects our pretax variable investment income for the prior five quarters, including $298 million in Q2 of 2024. Private equity portfolio, which makes up the vast majority of the VII asset balance, had a positive 2.3% return in the quarter, while our real estate equity funds had a negative 1.4% return in the quarter.
As a reminder, both private equity and real estate equity are reported on a one-quarter lag. Looking ahead, we expect VII returns to continue to improve over the course of second half of the year. On page six, we provide VII post-tax by segment for the last four quarters and the second quarter of 2024. As you can see in the chart, Asia, RIS and MetLife Holdings continue to hold the largest proportion of VII assets given their long-dated liability profile.
Now turning to page seven. The chart on the left of page illustrates the left of page illustrates the split of our net investment income between recurring and VII for the last three years, including second quarters of 2023 and 2024. Adjusted net investment income in Q2 of 2024 was up $120 million year-over-year. Recurring investment income has benefited from higher interest rates, partially offset by the roll-off from higher interest rates caps. In addition, we have seen VII improvement driven by higher private equity returns.
Turning your attention to the right side of the page. This shows our new money yield versus roll-off shows our new money yield versus roll-off yields since second quarter of 2021. Over the last nine quarters, new money yields have outpaced roll-off yields, consistent with higher interest rates. In the second quarter of 2024, our global new money rate achieved the yield of 6.27%, 63 basis points higher than the roll-off rate. We anticipate that the new money yields will remain above roll-off yields given the prevailing interest rate environment.
However, the spread can fluctuate depending on the mix of sales across our businesses. Now moving to expenses discussed on page eight, this chart shows a comparison of our direct expense ratio for full year 2023 of 12.2% and the first two quarters of 2024, both at 11.9%. As we have highlighted previously, we believe our full year direct expense ratio is the best way to measure performance due to fluctuations in quarterly results. Our Q2 direct expense ratio benefited from solid top line growth and ongoing expense discipline.
Looking ahead, we would expect our direct expense ratio to be higher in the second half of the year, consistent with the seasonal nature of our business. That said, our performance year-to-date positions us well to achieve a full year 2024 direct expense ratio of 12.3% or below demonstrating our consistent execution and a sustained efficiency mindset. I will now discuss our cash and capital positions on page nine.
Cash and liquid assets at the holding companies were $4.4 billion at June 30th, which is above our target cash buffer of $3 billion to $4 billion, but down from $5.2 billion at March 31st. The sequential decline in holding companies' cash is primarily a result of approximately $1.5 billion used in April for a debt maturity and a debt redemption, partially offset by a $500 million senior debt issuance in June.
Beyond this, cash of the holding companies reflects the net effects of subsidiary dividends, payment of our common stock dividend, and share repurchases of roughly $900 million in the second quarter, as well as holding company expenses and other cash flows. In addition, we have repurchased shares totaling approximately $270 million in July. For our US companies, preliminary second quarter year-to-date 2024 statutory operating earnings were approximately $1.9 billion, essentially flat year-over-year, while net income was approximately $1.3 billion.
We estimate that our total US statutory adjusted capital was approximately $18 billion as of June 30, down 2% from March 31, 2024, primarily due to dividends paid and derivative losses partially offset by operating earnings. Finally, we expect that Japan's solvency margin ratio to be approximately 670% as of June 30, which will be based on statutory statements that will be filed in the next few weeks. Before I wrap up, I would just like to highlight that we have an updated commercial mortgage loan slide as of June 30 in the appendix.
Overall, the CML portfolio continues to perform as expected with attractive loan-to-value and debt service coverage ratios as well as the expectation of modest losses. In summary, the underlying strength of our business fundamentals was evident with strong top line growth, disciplined underwriting and prudent expense management. Our Group Benefits segment achieved record earnings. Higher interest rates continue to support flows and spreads. And we continue to see improvement in variable investment income.
MetLife continues to move forward from a position of strength with a strong balance sheet and a diversified set of market-leading businesses, generating solid recurring free cash flow. And we are committed to deploying this free cash flow to achieve responsible growth and build long-term sustainable value for our customers and our shareholders.
And with that, I'll turn the call back to the operator for your questions.
