How did the Fund perform last year ?

For the 12-month period ended October 31, 2025, the Fund’s shares returned 22.34% on a net asset value basis and 22.38% on a market price basis.
In comparison, the Solactive GBS United States 500 Index TR (the “Index”) returned 22.32% for the same period.

What affected the Fund’s performance?

The U.S. large-cap stock market advanced during the reporting period, supported by strong earnings growth, heavy investment in artificial intelligence and infrastructure, and resilient consumer and business spending. U.S. stocks generally advanced during the reporting period, supported by moderating inflation, relatively low unemployment and a positive corporate backdrop amid Federal Reserve rate-cut expectations.
Large-cap stocks outperformed their mid- and small-cap counterparts, reflecting continued investor preference for multinational companies with strong balance sheets and diversified revenue streams.
Relatively strong-performing areas included information technology, communication services and consumer discretionary, driven by robust results from the Magnificent Seven and other large-cap technology firms.
Relatively weak-performing areas included materials, real estate and health care.
The difference in returns between the Fund and the Index resulted primarily from transaction costs and operating expenses that are not reflected in Index results.

How did the Fund perform last year ?

For the 12-month period ended October 31, 2025, the Fund’s shares returned 6.15% on a net asset value basis and 6.17% on a market price basis.
In comparison, the Bloomberg U.S. Aggregate Total Return Index (the “Index”) returned 6.16% for the same period.

What affected the Fund’s performance?

The U.S. bond market advanced during the reporting period, with all areas producing positive returns supported by attractive income levels, falling Treasury yields, easing inflation and expectations for Federal Reserve rate cuts.
Short and intermediate-maturity securities contributed positively as Treasury yields declined across the front and intermediate curve segments, supporting performance and boosting results in higher-quality interest-rate-sensitive holdings.
Tightening credit spreads and narrower mortgage option-adjusted spreads supported performance, aiding exposures to corporate credit, securitized assets and mortgage-related holdings as spread sectors outperformed during the reporting period.
Exposure to longer-maturity U.S. Treasuries modestly detracted, as rising 30-year yields caused longer-duration holdings to lag the strong performance of short and intermediate-maturity securities.

Factors Affecting Performance [Text Block]

How did the Fund perform last year ?

For the 12-month period ended October 31, 2025, the Fund’s shares returned 8.15% on a net asset value basis and 8.27% on a market price basis.
In comparison, the Bloomberg US Corporate High Yield Total Return Index (the “Index”) returned 8.16% for the same period.

What affected the Fund’s performance?

The U.S. high yield bond market advanced during the reporting period, outperforming investment‑grade bonds and Treasuries on easing recession fears, resilient corporate fundamentals and easing monetary policy.
The Fund’s strategy of overweighting individual securities identified by the credit model to have more favorable risk and relative value signals supported performance, while its risk-adjusted income focus further bolstered returns.
The difference in returns between the Fund and the Index resulted primarily from transaction costs and operating expenses that are not reflected in Index results.

Factors Affecting Performance [Text Block]

How did the Fund perform last year ?

For the 12-month period ended October 31, 2025, the Fund’s shares returned 2.19% on a net asset value basis and 2.40% on a market price basis.
In comparison, the MSCI EAFE^® Index (the “Index”) returned 23.03% for the same period.

What affected the Fund’s performance?

International equities advanced, led by financials and industrials. Banks benefited from wider interest margins and robust loan growth, while aerospace and defense companies rallied on increased global defense spending.
The Fund’s relative performance benefited from overweight exposure to the strong technology area, supported by robust Artificial Intelligence (AI)-driven demand and optimism across semiconductor supply chains.
Health care holdings detracted most from relative performance of the Fund due to overweight exposure to the weak sector and lagging returns. Industrial holdings also lagged their sector peers.
The Fund’s underweight exposure to financials detracted, as banks — where the Fund held no exposure — rallied sharply over the reporting period.
