Factors Affecting Performance [Text Block]	What impacted Fund performance over the reporting period? For the trailing one-year ended September 30, 2024 the Vontobel U.S. Equity Fund returned +25.47% vs. a +36.35% return for the S&P 500 Index. During the year, the market was narrowly focused on the artificial intelligence (AI) theme and the prospects for interest rate cuts by the US Federal Reserve. As a result, the Information Technology sector led the market higher, followed by Communication Services, Utilities and Financials. On the flip side, Energy was the lone sector to post negative returns, while more defensive sectors such as Health Care and Consumer Staples lagged in a strong rally. Relative performance vs. the index was held back for an underweight to and stock selection within Information Technology. The strategy does not hold semiconductor companies such as Nvidia and Broadcom, which have been beneficiaries of increased spending on AI. Likewise, not owning Meta within the Communication Services sector detracted as it ramps up it’s AI spending. Our more defensive posture with overweight to Consumer Staples and Health Care also detracted from relative returns during the year. On the positive side, the strategy’s lack of exposure to the poorly performing Energy sector added to relative returns. Stock selection within Materials contributed to performance as holdings in CRH and Sherwin-Williams saw improved earnings outlook driven by strong pricing power. Lastly, stock selection within Consumer Discretionary contributed to performance mainly to not holding poorly performing Tesla which has seen increased competition in the EV space.

Factors Affecting Performance [Text Block]	What impacted Fund performance over the reporting period? The Fund returned 32.8% since inception while the MSCI AC World Net Total Return was up 34.2%. The strongest performance delivered our Clean Energy Infrastructure pillar where grid related companies outperformed renewable energy component producers. Building Technology and Clean Water also performed strongly while Lifecycle Management was more or less in line with global equity market returns. With Resource Efficient Industry and Low Emission Transportation, two of our pillars underperformed. The latter suffered especially from sluggish EV markets. On a more traditional sector view the underperformance of the Fund is mainly related to Information Technology as our holdings did not hold up against Mag7's performance, which were strong drivers for market returns. Moreover, automotive related exposure (semiconductors and batteries) suffered from muted demand and rising price competition in the EV space. Positive contributions resulted mainly from Industrials (across different impact pillars) and Materials.
