WHAT FACTORS INFLUENCED PERFORMANCE FOR THE PERIOD?
During the Period, the Fund returned 11.28% (on a NAV basis). This marks another solid year of performance driven by a resilient economy and strong corporate profits. In addition, the Fund continues to benefit from rising interest in AI-related investments through its high exposure to companies with innovative intangible assets. Moreover, the Fund has mostly recovered losses stemming from tariff tensions earlier this year.

Despite robust absolute returns, the Fund ended the Fiscal Year slightly behind the Solactive GBS United States 1000 Index. This was mostly the result of its relatively lower weight in U.S. mega-cap tech stocks (i.e., the so-called “Magnificent 7*”), which put up another exceptional year of returns. However, as explained in our recent investor letter (“Beyond the Magnificent 7*”), we believe the Fund’s positioning is beneficial for investors – providing a way to diversify from top-heavy indexes to cheaper stocks, while still maintaining exposure to the modern, intangible economy.

Factors Affecting Performance [Text Block]
WHAT FACTORS INFLUENCED PERFORMANCE FOR THE PERIOD?
Since its inception on Sep 9, 2024, the Fund returned 14.56% (on a NAV basis). This strong performance was driven by a bullish environment for global risk assets, especially in the later 2025 sub-period, when non-U.S. stocks excelled as investors fled rising U.S.-specific geopolitical risk related to Trump’s trade war. During this period, investors rotated out of not only U.S. stocks but also the U.S. dollar, benefiting the Fund as it does not currency hedge.

On a relative basis, the Fund outperformed the broader global stock index, returning 14.56% compared to 9.96% for the Solactive GBS Global Markets All Cap Index. While this was in part due to the relative outperformance of non-U.S. stocks, a more important driver was the Fund's heavier allocation to intangible-intensive companies, especially those with strong brand capital, which outperformed over this period.
