Factors Affecting Performance [Text Block]

How did the Fund perform and what affected its performance?

The A Class of the Fund returned -3.77% (with sales charges) and 2.07% (without sales charges) for the twelve months ended December 31, 2025, compared to the S&P 500^® Index TR return of 17.88%.

The investment strategy of the Fund’s sub-advisor is designed to capitalize on price trends in a broad range of global markets across multiple asset classes.
The twelve‑month period featured a split environment for trend-following strategies: the first half was hindered by a series of macroeconomic shocks, while clearer trends in the second half created a more favorable opportunity set.
Returns were driven by strength in equities and currencies, which offset weakness in commodities and fixed income. While equities benefited from a renewed ‘risk‑on’ tone in the second half of the year, fixed income struggled as fluctuating rate‑cut expectations kept trends from establishing.

*Value at Risk (“VaR”) is a measure of the potential loss in value of a portfolio over a defined period for a given confidence interval. A one-day VaR at the 95% confidence level represents that there is a 5% probability that the mark-to-market loss on the portfolio over a one day horizon will exceed this value (assuming normal markets and no trading in the portfolio).

Factors Affecting Performance [Text Block]

How did the Fund perform and what affected its performance?

The Investor Class of the Fund returned 2.15% for the twelve months ended December 31, 2025, compared to the S&P 500^® Index TR return of 17.88%.

The investment strategy of the Fund’s sub-advisor is designed to capitalize on price trends in a broad range of global markets across multiple asset classes.
The twelve‑month period featured a split environment for trend-following strategies: the first half was hindered by a series of macroeconomic shocks, while clearer trends in the second half created a more favorable opportunity set.
Returns were driven by strength in equities and currencies, which offset weakness in commodities and fixed income. While equities benefited from a renewed ‘risk‑on’ tone in the second half of the year, fixed income struggled as fluctuating rate‑cut expectations kept trends from establishing.

Factors Affecting Performance [Text Block]

How did the Fund perform and what affected its performance?

The Y Class of the Fund returned 2.42% for the twelve months ended December 31, 2025, compared to the S&P 500^® Index TR return of 17.88%.

The investment strategy of the Fund’s sub-advisor is designed to capitalize on price trends in a broad range of global markets across multiple asset classes.
The twelve‑month period featured a split environment for trend-following strategies: the first half was hindered by a series of macroeconomic shocks, while clearer trends in the second half created a more favorable opportunity set.
Returns were driven by strength in equities and currencies, which offset weakness in commodities and fixed income. While equities benefited from a renewed ‘risk‑on’ tone in the second half of the year, fixed income struggled as fluctuating rate‑cut expectations kept trends from establishing.

Factors Affecting Performance [Text Block]

How did the Fund perform and what affected its performance?

The A Class of the Fund returned 1.83% (with sales charges) and 8.04% (without sales charges) for the twelve months ended December 31, 2025, compared to the S&P 500^® Index TR return of 17.88%, the Bloomberg Global-Aggregate Total Return Index Value Hedged USD return of 4.86% and the 60% MSCI World Index (Hedged to USD) / 40% Bloomberg Global-Aggregate Total Return Index Value Hedged USD return of 13.29%.

The investment strategy of the Fund’s sub-advisor is designed to maintain a targeted risk profile through dynamic implementation and investing across a broad range of asset classes.
The market backdrop was erratic over the twelve-month period, caused largely by shifts in U.S. trade policy in the second quarter, and subsequently rallied in the second half of the year.
Equities led the Fund’s performance contribution for the full period, with inflation-sensitive assets and credit exposures also contributing, while fixed income was the lone detractor with a modest negative impact on overall results.

Factors Affecting Performance [Text Block]

How did the Fund perform and what affected its performance?

The Investor Class of the Fund returned 7.73% for the twelve months ended December 31, 2025, compared to the S&P 500^® Index TR return of 17.88%, the Bloomberg Global-Aggregate Total Return Index Value Hedged USD return of 4.86% and the 60% MSCI World Index (Hedged to USD) / 40% Bloomberg Global-Aggregate Total Return Index Value Hedged USD return of 13.29%.

The investment strategy of the Fund’s sub-advisor is designed to maintain a targeted risk profile through dynamic implementation and investing across a broad range of asset classes.
The market backdrop was erratic over the twelve-month period, caused largely by shifts in U.S. trade policy in the second quarter, and subsequently rallied in the second half of the year.
Equities led the Fund’s performance contribution for the full period, with inflation-sensitive assets and credit exposures also contributing, while fixed income was the lone detractor with a modest negative impact on overall results.

* Value at Risk (“VaR”) is a measure of the potential loss in value of a portfolio over a defined period for a given confidence interval. A one-day VaR at the 95% confidence level represents that there is a 5% probability that the mark-to-market loss on the portfolio over a one day horizon will exceed this value (assuming normal markets and no trading in the portfolio).

Factors Affecting Performance [Text Block]

How did the Fund perform and what affected its performance?

The Y Class of the Fund returned 8.18% for the twelve months ended December 31, 2025, compared to the S&P 500^® Index TR return of 17.88%, the Bloomberg Global-Aggregate Total Return Index Value Hedged USD return of 4.86% and the 60% MSCI World Index (Hedged to USD) / 40% Bloomberg Global-Aggregate Total Return Index Value Hedged USD return of 13.29%.

The investment strategy of the Fund’s sub-advisor is designed to maintain a targeted risk profile through dynamic implementation and investing across a broad range of asset classes.
The market backdrop was erratic over the twelve-month period, caused largely by shifts in U.S. trade policy in the second quarter, and subsequently rallied in the second half of the year.
Equities led the Fund’s performance contribution for the full period, with inflation-sensitive assets and credit exposures also contributing, while fixed income was the lone detractor with a modest negative impact on overall results.

Factors Affecting Performance [Text Block]

How did the Fund perform and what affected its performance?

The Investor Class of the Fund returned 15.86% for the twelve months ended December 31, 2025, compared to the S&P 500^® Index TR return of 17.88% and the Russell 1000^® Growth Index return of 18.56%.

Broad market performance during the period was driven higher primarily by robust earnings growth, bolstered by AI-fueled gains from mega-cap tech and broadening profitability across sectors, supported by Federal Reserve rate cuts and easing trade tensions.
The Fund’s diversified systematic strategy focused on large cap growth companies delivered positive returns, but trailed the broad market rally led by mega-cap tech companies.
The Fund generated positive performance in all sectors where it invested, except within Consumer Staples and Utilities. The Fund's holdings in the Information Technology and Communication Services sectors contributed meaningfully to the return of the Fund.

Factors Affecting Performance [Text Block]

How did the Fund perform and what affected its performance?

The Y Class of the Fund returned 16.17% for the twelve months ended December 31, 2025, compared to the S&P 500^® Index TR return of 17.88% and the Russell 1000^® Growth Index return of 18.56%.

Broad market performance during the period was driven higher primarily by robust earnings growth, bolstered by AI-fueled gains from mega-cap tech and broadening profitability across sectors, supported by Federal Reserve rate cuts and easing trade tensions.
The Fund’s diversified systematic strategy focused on large cap growth companies delivered positive returns, but trailed the broad market rally led by mega-cap tech companies.
The Fund generated positive performance in all sectors where it invested, except within Consumer Staples and Utilities. The Fund's holdings in the Information Technology and Communication Services sectors contributed meaningfully to the return of the Fund.

Factors Affecting Performance [Text Block]

How did the Fund perform and what affected its performance?

The A Class of the Fund returned 16.64% (with sales charges) and 23.77% (without sales charges) for the twelve months ended December 31, 2025, compared to the S&P 500^® Index TR return of 17.88% and the Russell 1000^® Value Index return of 15.91%.

Broad market performance during the period was driven higher primarily by robust earnings growth, bolstered by AI-fueled gains from mega-cap tech and broadening profitability across sectors, supported by Federal Reserve rate cuts and easing trade tensions.
The Fund’s large cap value strategy, grounded in systematic diversification, capitalized on widening market strength to deliver strong performance during the twelve-month period.
The Fund generated positive performance in all sectors where it invested, except within the Real Estate sector. The Fund's holdings in the Health Care and Financials sectors contributed meaningfully to the return of the Fund.

Factors Affecting Performance [Text Block]

How did the Fund perform and what affected its performance?

The Investor Class of the Fund returned 23.81% for the twelve months ended December 31, 2025, compared to the S&P 500^® Index TR return of 17.88% and the Russell 1000^® Value Index return of 15.91%.

Broad market performance during the period was driven higher primarily by robust earnings growth, bolstered by AI-fueled gains from mega-cap tech and broadening profitability across sectors, supported by Federal Reserve rate cuts and easing trade tensions.
The Fund’s large cap value strategy, grounded in systematic diversification, capitalized on widening market strength to deliver strong performance during the twelve-month period.
The Fund generated positive performance in all sectors where it invested, except within the Real Estate sector. The Fund's holdings in the Health Care and Financials sectors contributed meaningfully to the return of the Fund.

Factors Affecting Performance [Text Block]

How did the Fund perform and what affected its performance?

The Y Class of the Fund returned 24.11% for the twelve months ended December 31, 2025, compared to the S&P 500^® Index TR return of 17.88% and the Russell 1000^® Value Index return of 15.91%.

Broad market performance during the period was driven higher primarily by robust earnings growth, bolstered by AI-fueled gains from mega-cap tech and broadening profitability across sectors, supported by Federal Reserve rate cuts and easing trade tensions.
The Fund’s large cap value strategy, grounded in systematic diversification, capitalized on widening market strength to deliver strong performance during the twelve-month period.
The Fund generated positive performance in all sectors where it invested, except within the Real Estate sector. The Fund's holdings in the Health Care and Financials sectors contributed meaningfully to the return of the Fund.

Factors Affecting Performance [Text Block]

How did the Fund perform and what affected its performance?

The A Class of the Fund returned 6.05% (with sales charges) and 12.53% (without sales charges) for the twelve months ended December 31, 2025, compared to the S&P 500^® Index TR return of 17.88% and the Russell Midcap^® Growth Index return of 8.66%.

Broad market performance during the period was driven higher primarily by AI-fueled gains from mega-cap tech and broadening profitability across sectors, supported by Federal Reserve rate cuts and easing trade tensions.
The Fund focuses its investments on medium-capitalization companies, which did not keep up with the broader market gains driven largely by mega-cap companies.
The Fund’s performance was positive in all sectors where it invested, except within the Materials, Real Estate and Consumer Staples sectors. The Fund’s holdings in the Information Technology and Industrials sectors contributed meaningfully to the positive return of the Fund.

The Fund’s performance was positive in all sectors where it invested, except within the Materials, Real Estate and Consumer Staples sectors. The Fund’s holdings in the Information Technology and Industrials sectors contributed meaningfully to the positive return of the Fund.

Factors Affecting Performance [Text Block]

How did the Fund perform and what affected its performance?

The R5 Class of the Fund returned 12.85% for the twelve months ended December 31, 2025, compared to the S&P 500^® Index TR return of 17.88% and the Russell Midcap^® Growth Index return of 8.66%.

Broad market performance during the period was driven higher primarily by AI-fueled gains from mega-cap tech and broadening profitability across sectors, supported by Federal Reserve rate cuts and easing trade tensions.
The Fund focuses its investments on medium-capitalization companies, which did not keep up with the broader market gains driven largely by mega-cap companies.
The Fund’s performance was positive in all sectors where it invested, except within the Materials, Real Estate and Consumer Staples sectors. The Fund’s holdings in the Information Technology and Industrials sectors contributed meaningfully to the positive return of the Fund.

The Fund’s performance was positive in all sectors where it invested, except within the Materials, Real Estate and Consumer Staples sectors. The Fund’s holdings in the Information Technology and Industrials sectors contributed meaningfully to the positive return of the Fund.

Factors Affecting Performance [Text Block]

How did the Fund perform and what affected its performance?

The A Class of the Fund returned 5.17% (with sales charges) and 11.55% (without sales charges) for the twelve months ended December 31, 2025, compared to the S&P 500^® Index TR return of 17.88% and the Russell 2000^® Growth Index return of 13.01%.

Broad market performance during the period was driven higher primarily by robust earnings growth, bolstered by AI-fueled gains from mega-cap tech and broadening profitability across sectors, supported by Federal Reserve rate cuts and easing trade tensions.
The Fund focuses its investments on small capitalization companies, which did not keep up with the broader market gains driven largely by mega-cap companies.
The Fund’s performance was positive in six of the nine sectors where it invested, but the Fund’s holdings within those six sectors underperformed the broader small-capitalization market. The Fund’s performance was negative in the Consumer Staples, Materials and Consumer Discretionary sectors.

Broad market performance during the period was driven higher primarily by robust earnings growth, bolstered by AI-fueled gains from mega-cap tech and broadening profitability across sectors, supported by Federal Reserve rate cuts and easing trade tensions.
The Fund focuses its investments on small capitalization companies, which did not keep up with the broader market gains driven largely by mega-cap companies.
The Fund’s performance was positive in six of the nine sectors where it invested, but the Fund’s holdings within those six sectors underperformed the broader small-capitalization market. The Fund’s performance was negative in the Consumer Staples, Materials and Consumer Discretionary sectors.

Factors Affecting Performance [Text Block]

How did the Fund perform and what affected its performance?

The R5 Class of the Fund returned 11.82% for the twelve months ended December 31, 2025, compared to the S&P 500^® Index TR return of 17.88% and the Russell 2000^® Growth Index return of 13.01%.

Broad market performance during the period was driven higher primarily by robust earnings growth, bolstered by AI-fueled gains from mega-cap tech and broadening profitability across sectors, supported by Federal Reserve rate cuts and easing trade tensions.
The Fund focuses its investments on small capitalization companies, which did not keep up with the broader market gains driven largely by mega-cap companies.
The Fund’s performance was positive in six of the nine sectors where it invested, but the Fund’s holdings within those six sectors underperformed the broader small-capitalization market. The Fund’s performance was negative in the Consumer Staples, Materials and Consumer Discretionary sectors.

The R6 Class of the Fund returned 11.92% for the twelve months ended December 31, 2025, compared to the S&P 500^® Index TR return of 17.88% and the Russell 2000^® Growth Index return of 13.01%.

Broad market performance during the period was driven higher primarily by robust earnings growth, bolstered by AI-fueled gains from mega-cap tech and broadening profitability across sectors, supported by Federal Reserve rate cuts and easing trade tensions.
The Fund focuses its investments on small capitalization companies, which did not keep up with the broader market gains driven largely by mega-cap companies.
The Fund’s performance was positive in six of the nine sectors where it invested, but the Fund’s holdings within those six sectors underperformed the broader small-capitalization market. The Fund’s performance was negative in the Consumer Staples, Materials and Consumer Discretionary sectors.
