Factors Affecting Performance [Text Block]
HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE?
For the 12-month period ended October 31, 2024, the Fund gained +23.64% net of fees, compared to a return of +34.17% by its benchmark index.
WHAT FACTORS INFLUENCED PERFORMANCE
Overweight positions in U.S.-listed utilities and renewables, such as NextEra Energy and Dominion Energy, positively impacted relative performance.
Energy midstream performed strongly, driven by rising U.S. energy demand and robust appetite for U.S. liquified natural gas exports to Europe and Asia.
Underweight exposure to the airports sector, favoring shorter-haul tourism-focused airports, also aided relative returns.
Overweight exposure to toll roads detracted from relative performance.  Additionally, exposure to Chinese-listed infrastructure stocks, despite their cheap valuations, disappointed and detracted from relative returns.

HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE?
For the 12-month period ended October 31, 2024, the Fund gained +30.35% net of fees, compared to a return of +38.02% by its benchmark index.
WHAT FACTORS INFLUENCED PERFORMANCE
Overweight positions in U.S.-listed utilities and renewables, such as NextEra Energy and Dominion Energy, positively impacted relative performance.
Underweight exposure to the Energy Midstream space detracted from relative performance. The sector performed strongly during the period under review as robust commodity prices and a healthy outlook for the U.S. economy provided a supportive backdrop to these companies.

Elevated interest rates and lower power prices weighed on the portfolio’s renewables-focused utilities.
