Factors Affecting Performance [Text Block]

How did the Fund perform and what affected its performance?

The A Class of the Fund returned 1.95% (with sales charges) and 8.17% (without sales charges) for the twelve months ended October 31, 2025, compared to the S&P 500 Index return of 21.45%, the Bloomberg U.S. Aggregate Bond Index return of 6.16% and the Balanced Composite Index (40% Bloomberg US Aggregate Bond Index/60% Russell 1000 Value Index) return of 9.28%.

• Broad market performance rallied during the twelve-month period as an easing of monetary policy began and risk-on sentiment drove performance within the AI theme.

• The Fund’s diversified strategy of equity and fixed income investing achieved returns through capital appreciation and income.

• The Fund's equity portion was positive in seven of the eleven sectors where it invested, except within the Materials, Health Care, Consumer Staples and Real Estate sectors. The Fund's holdings in the Financials, Information Technology and Industrials sectors contributed meaningfully to the return of the Fund. The Fund’s fixed-income holdings contributed positively to performance during the twelve-month period.
