Factors Affecting Performance [Text Block]
WHAT FACTORS INFLUENCED PERFORMANCE FOR THE PERIOD?
For the 12-month period ended March 31, 2026, the Fund returned +14.10%, outperforming its benchmark, the S&P 500 Equal Weight Index, which returned +12.80%. The Fund primarily invested in large- and mid-cap U.S. equities across various sectors, with a focus on companies that meet rigorous environmental, social, and governance (ESG) criteria.

TOP PERFORMANCE CONTRIBUTORS

The Fund’s performance improved notably in the final quarter of the period. Key drivers included the exclusion of Tesla Inc. due to ESG criteria and underweight exposure to NVIDIA Corp., both of which declined sharply. The Fund’s equal weight methodology also boosted results through overweights in strong performers like AutoZone and O’Reilly Automotive.

TOP PERFORMANCE DETRACTORS

Information Technology Detracted from relative performance as the Fund’s largest sector drag. CHGX’s equal weight exposure to mega caps like Apple Inc. and NVIDIA Corp. limited upside participation earlier in the year and contributed to underperformance. However, the strategy proved protective in Q1, when NVIDIA fell sharply and CHGX’s underweight contributed positively to relative performance. Meanwhile, Microsoft Corp., removed mid-year for ESG reasons, contributed positively to relative performance. Together, these positions illustrate how the Fund’s approach reduces concentration risk and can cushion downside, though it may lag when a few dominant stocks drive the benchmark.

Consumer Staples — Detracted largely due to poor stock selection. Estée Lauder significantly underperformed. Nike Inc. also declined, further weighing on sector attribution.

Consumer Discretionary — Detracted due to selection effect. A notable laggard was Lennar Corp., a homebuilder that underperformed its benchmark peers.

Utilities — Both allocation and selection effects were negative, with holdings underperforming benchmark peers and the Fund maintaining an unfavorable weighting.
