Factors Affecting Performance [Text Block]
WHAT FACTORS INFLUENCED PERFORMANCE FOR THE PERIOD?
During the Period, ITAN returned 40.21% (on a NAV basis). This marked a strong year of performance, as the Fund’s focus on innovative firms with robust intangible assets continued to generate positive returns.

ITAN also outperformed in relative terms, with its 40.21% return exceeding the 28.99% return of the Solactive GBS United States 1000 Net Total Return Index by 11.22%. Outperformance was primarily fueled by strong security selection. For example, ITAN achieved this outperformance despite significantly lower exposure to AI infrastructure stocks, such as the Magnificent 7*, which the Fund has been rotating out of due to rising valuations and capital intensity.

* Amazon, Meta, Alphabet, Nvidia, Tesla, Microsoft, and Apple.

Factors Affecting Performance [Text Block]
WHAT FACTORS INFLUENCED PERFORMANCE FOR THE PERIOD?
During the Period, DTAN returned 20.07% (on a NAV basis). This strong performance was driven by a resilient global stock market that largely shrugged off geopolitical risks, most notably in Iran.

Despite robust absolute returns, DTAN underperformed the Solactive GBS Global Markets All Cap USD Index, which returned 31.05%. This was primarily driven by DTAN’s focus on non-U.S. developed market stocks, which underperformed both U.S. and emerging market stocks, due mostly to their relative lack of AI infrastructure exposure. A secondary driver was DTAN’s underweight to non-U.S. developed market financial stocks, which surged despite scoring poorly on many intangible metrics. Despite these sector headwinds, DTAN actually produced strong security selection alpha, with the Fund’s holdings outperforming their respective sectors.
