Factors Affecting Performance [Text Block]

How did the Fund perform and what affected its performance?

The R5 Class of the Fund returned 24.37% for the twelve months ended October 31, 2024, compared to the S&P 500 Index return of 38.02%, the Bloomberg U.S. Aggregate Bond Index return of 10.55% and the Balanced Composite Index return of 22.49%.

• Broad market performance rallied during the twelve-month period as central banks cut rates globally and the probability of a soft landing increased.

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

• The Fund's holdings in the Information Technology and Financials sectors contributed materially to the Fund's performance, while holdings in the Energy sector detracted from the Fund’s performance over the period. The Fund’s fixed-income holdings contributed negatively to performance during the twelve-month period.

Factors Affecting Performance [Text Block]

How did the Fund perform and what affected its performance?

The Investor Class of the Fund returned 24.01% for the twelve months ended October 31, 2024, compared to the S&P 500 Index return of 38.02%, the Bloomberg U.S. Aggregate Bond Index return of 10.55% and the Balanced Composite Index return of 22.49%.

• Broad market performance rallied during the twelve-month period as central banks cut rates globally and the probability of a soft landing increased.

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

• The Fund's holdings in the Information Technology and Financials sectors contributed materially to the Fund's performance, while holdings in the Energy sector detracted from the Fund’s performance over the period. The Fund’s fixed-income holdings contributed negatively to performance during the twelve-month period.

The A Class of the Fund returned 16.86% (with sales charges) and 24.03% (without sales charges) for the twelve months ended October 31, 2024, compared to the S&P 500 Index return of 38.02%, the Bloomberg U.S. Aggregate Bond Index return of 10.55% and the Balanced Composite Index return of 22.49%.

• Broad market performance rallied during the twelve-month period as central banks cut rates globally and the probability of a soft landing increased.

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

• The Fund's holdings in the Information Technology and Financials sectors contributed materially to the Fund's performance, while holdings in the Energy sector detracted from the Fund’s performance over the period. The Fund’s fixed-income holdings contributed negatively to performance during the twelve-month period.

Factors Affecting Performance [Text Block]

How did the Fund perform and what affected its performance?

The R5 Class of the Fund returned 31.97% for the twelve months ended October 31, 2024, compared to the S&P 500^® Index TR return of 38.02% and the Russell 1000^® Value Index return of 30.98%. 

• Broad market performance during the twelve-month period benefited from the loosening of monetary policy as inflation eased, coinciding with the increased prospect of a soft landing.

• The Fund’s strategy of selecting undervalued securities through a bottom-up approach provided strong returns during the period.

• The Fund's holdings in the Information Technology and Financials sectors contributed materially to the Fund's performance, while holdings in the Energy sector detracted from the Fund’s performance over the period.

Factors Affecting Performance [Text Block]

How did the Fund perform and what affected its performance?

The Investor Class of the Fund returned 31.54% for the twelve months ended October 31, 2024, compared to the S&P 500^® Index TR return of 38.02% and the Russell 1000^® Value Index return of 30.98%. 

• Broad market performance during the twelve-month period benefited from the loosening of monetary policy as inflation eased, coinciding with the increased prospect of a soft landing.

• The Fund’s strategy of selecting undervalued securities through a bottom-up approach provided strong returns during the period.

• The Fund's holdings in the Information Technology and Financials sectors contributed materially to the Fund's performance, while holdings in the Energy sector detracted from the Fund’s performance over the period.

Factors Affecting Performance [Text Block]

How did the Fund perform and what affected its performance?

The A Class of the Fund returned 23.96% (with sales charges) and 31.53% (without sales charges) for the twelve months ended October 31, 2024, compared to the S&P 500^® Index TR return of 38.02% and the Russell 1000^® Value Index return of 30.98%. 

• Broad market performance during the twelve-month period benefited from the loosening of monetary policy as inflation eased, coinciding with the increased prospect of a soft landing.

• The Fund’s strategy of selecting undervalued securities through a bottom-up approach provided strong returns during the period.

• The Fund's holdings in the Information Technology and Financials sectors contributed materially to the Fund's performance, while holdings in the Energy sector detracted from the Fund’s performance over the period.

Factors Affecting Performance [Text Block]

How did the Fund perform and what affected its performance?

The C Class of the Fund returned 29.51% (with sales charges) and 30.51% (without sales charges) for the twelve months ended October 31, 2024, compared to the S&P 500^® Index TR return of 38.02% and the Russell 1000^® Value Index return of 30.98%. 

• Broad market performance during the twelve-month period benefited from the loosening of monetary policy as inflation eased, coinciding with the increased prospect of a soft landing.

• The Fund’s strategy of selecting undervalued securities through a bottom-up approach provided strong returns during the period.

• The Fund's holdings in the Information Technology and Financials sectors contributed materially to the Fund's performance, while holdings in the Energy sector detracted from the Fund’s performance over the period.

Factors Affecting Performance [Text Block]

How did the Fund perform and what affected its performance?

The R6 Class of the Fund returned 32.02% for the twelve months ended October 31, 2024, compared to the S&P 500^® Index TR return of 38.02% and the Russell 1000^® Value Index return of 30.98%. 

• Broad market performance during the twelve-month period benefited from the loosening of monetary policy as inflation eased, coinciding with the increased prospect of a soft landing.

• The Fund’s strategy of selecting undervalued securities through a bottom-up approach provided strong returns during the period.

• The Fund's holdings in the Information Technology and Financials sectors contributed materially to the Fund's performance, while holdings in the Energy sector detracted from the Fund’s performance over the period.

Factors Affecting Performance [Text Block]

How did the Fund perform and what affected its performance?

The R5 Class of the Fund returned 28.05% for the twelve months ended October 31, 2024, compared to the S&P 500^® Index TR return of 38.02% and the Russell 2000^® Value Index return of 31.77%.

• Broad market performance during the period was primarily driven by a 50-basis point interest rate cut, the first since the pandemic and increasing optimism that the U.S. economy could avoid a recession.

• The Fund’s focus is on finding undervalued, high-quality companies with above average earnings growth.

• The Fund's performance was positive in ten of the eleven sectors where it invested, except for the Energy sector. The Fund's holdings in the Information Technology, Industrials and Financials sectors were the top contributors to the Fund's positive relative performance, while holdings in the Consumer Discretionary, Materials and Health Care sectors detracted from relative returns.

Factors Affecting Performance [Text Block]

How did the Fund perform and what affected its performance?

The Investor Class of the Fund returned 27.60% for the twelve months ended October 31, 2024, compared to the S&P 500^® Index TR return of 38.02% and the Russell 2000^® Value Index return of 31.77%.

• Broad market performance during the period was primarily driven by a 50-basis point interest rate cut, the first since the pandemic and increasing optimism that the U.S. economy could avoid a recession.

• The Fund’s focus is on finding undervalued, high-quality companies with above average earnings growth.

• The Fund's performance was positive in ten of the eleven sectors where it invested, except for the Energy sector. The Fund's holdings in the Information Technology, Industrials and Financials sectors were the top contributors to the Fund's positive relative performance, while holdings in the Consumer Discretionary, Materials and Health Care sectors detracted from relative returns.

Factors Affecting Performance [Text Block]

How did the Fund perform and what affected its performance?

The Advisor Class of the Fund returned 27.40% for the twelve months ended October 31, 2024, compared to the S&P 500^® Index TR return of 38.02% and the Russell 2000^® Value Index return of 31.77%.

• Broad market performance during the period was primarily driven by a 50-basis point interest rate cut, the first since the pandemic and increasing optimism that the U.S. economy could avoid a recession.

• The Fund’s focus is on finding undervalued, high-quality companies with above average earnings growth.

• The Fund's performance was positive in ten of the eleven sectors where it invested, except for the Energy sector.

Factors Affecting Performance [Text Block]

How did the Fund perform and what affected its performance?

The A Class of the Fund returned 20.16% (with sales charges) and 27.50% (without sales charges) for the twelve months ended October 31, 2024, compared to the S&P 500^® Index TR return of 38.02% and the Russell 2000^® Value Index return of 31.77%.

• Broad market performance during the period was primarily driven by a 50-basis point interest rate cut, the first since the pandemic and increasing optimism that the U.S. economy could avoid a recession.

• The Fund’s focus is on finding undervalued, high-quality companies with above average earnings growth.

• The Fund's performance was positive in ten of the eleven sectors where it invested, except for the Energy sector. The Fund's holdings in the Information Technology, Industrials and Financials sectors were the top contributors to the Fund's positive relative performance, while holdings in the Consumer Discretionary, Materials and Health Care sectors detracted from relative returns.

Factors Affecting Performance [Text Block]

How did the Fund perform and what affected its performance?

The C Class of the Fund returned 25.56% (with sales charges) and 26.56% (without sales charges) for the twelve months ended October 31, 2024, compared to the S&P 500^® Index TR return of 38.02% and the Russell 2000^® Value Index return of 31.77%.

• Broad market performance during the period was primarily driven by a 50-basis point interest rate cut, the first since the pandemic and increasing optimism that the U.S. economy could avoid a recession.

• The Fund’s focus is on finding undervalued, high-quality companies with above average earnings growth.

• The Fund's performance was positive in ten of the eleven sectors where it invested, except for the Energy sector. The Fund's holdings in the Information Technology, Industrials and Financials sectors were the top contributors to the Fund's positive relative performance, while holdings in the Consumer Discretionary, Materials and Health Care sectors detracted from relative returns.

Factors Affecting Performance [Text Block]

How did the Fund perform and what affected its performance?

The R5 Class of the Fund returned 22.05% for the twelve months ended October 31, 2024, compared to the MSCI^® EAFE Index (Net) return of 22.97%.

• Broad market performance during the last twelve months benefited from many developed nations loosening monetary policy as inflation eased and the increased prospect of a soft landing even as an interest rate hike by the Bank of Japan in late July caused some market turmoil.

• The Fund’s focus on value through a bottom-up approach and diversification through its multi manager strategy provided strong returns during the period.

• The Fund's holdings in the Industrials and Financials sectors contributed to the Fund's performance, while holdings in the Information Technology sector detracted from performance.

Factors Affecting Performance [Text Block]

How did the Fund perform and what affected its performance?

The Advisor Class of the Fund returned 21.50% for the twelve months ended October 31, 2024, compared to the MSCI^® EAFE Index (Net) return of 22.97%.

• Broad market performance during the last twelve months benefited from many developed nations loosening monetary policy as inflation eased and the increased prospect of a soft landing even as an interest rate hike by the Bank of Japan in late July caused some market turmoil.

• The Fund’s focus on value through a bottom-up approach and diversification through its multi manager strategy provided strong returns during the period.

• The Fund's holdings in the Industrials and Financials sectors contributed to the Fund's performance, while holdings in the Information Technology sector detracted from performance.

Factors Affecting Performance [Text Block]

How did the Fund perform and what affected its performance?

The Y Class of the Fund returned 22.01% for the twelve months ended October 31, 2024, compared to the MSCI^® EAFE Index (Net) return of 22.97%.

• Broad market performance during the last twelve months benefited from many developed nations loosening monetary policy as inflation eased and the increased prospect of a soft landing even as an interest rate hike by the Bank of Japan in late July caused some market turmoil.

• The Fund’s focus on value through a bottom-up approach and diversification through its multi manager strategy provided strong returns during the period.

• The Fund's holdings in the Industrials and Financials sectors contributed to the Fund's performance, while holdings in the Information Technology sector detracted from performance.

Factors Affecting Performance [Text Block]

How did the Fund perform and what affected its performance?

The R6 Class of the Fund returned 22.17% for the twelve months ended October 31, 2024, compared to the MSCI^® EAFE Index (Net) return of 22.97%.

• Broad market performance during the last twelve months benefited from many developed nations loosening monetary policy as inflation eased and the increased prospect of a soft landing even as an interest rate hike by the Bank of Japan in late July caused some market turmoil.

• The Fund’s focus on value through a bottom-up approach and diversification through its multi manager strategy provided strong returns during the period.

• The Fund's holdings in the Industrials and Financials sectors contributed to the Fund's performance, while holdings in the Information Technology sector detracted from performance.

Factors Affecting Performance [Text Block]

How did the Fund perform and what affected its performance?

The R5 Class of the Fund returned 11.40% for the twelve months ended October 31, 2024, compared to the Bloomberg U.S. Aggregate Bond Index return of 10.55%.

• The Federal Reserve cut the Federal Funds Rate by 0.50% in September 2024.

• In anticipation of a slower economy, the Fund ended the period with a longer duration of 7.5 years compared to 6.1 years for the Index, which led to outperformance.

• The Fund was underweight in Corporates due to narrow credit spreads. This detracted from performance as Corporates were the best performing sector in the Index, returning 13.6%. Lower-quality Corporate bonds outperformed, while the Fund holds only higher-quality bonds.

• The Fund’s overweighting of Agency Mortgages performed well, although returns were in line with duration-equivalent Treasury bonds.

Factors Affecting Performance [Text Block]

How did the Fund perform and what affected its performance?

The Y Class of the Fund returned 11.22% for the twelve months ended October 31, 2024, compared to the Bloomberg U.S. Aggregate Bond Index return of 10.55%.

• The Federal Reserve cut the Federal Funds Rate by 0.50% in September 2024.

• In anticipation of a slower economy, the Fund ended the period with a longer duration of 7.5 years compared to 6.1 years for the Index, which led to outperformance.

• The Fund’s overweighting of Agency Mortgages performed well, although returns were in line with duration-equivalent Treasury bonds.

Factors Affecting Performance [Text Block]

How did the Fund perform and what affected its performance?

The R5 Class of the Fund returned 18.52% for the twelve months ended October 31, 2024, compared to the MSCI^® EAFE Index (Net) return of 22.97% and the MSCI^® ACWI ex USA Small Cap Index (Net) return of 23.73%.

• The Fund’s strategy of informed momentum investing struggled as investors rotated into lower momentum and weaker quality stocks in the latter part of the twelve-month period with the loosening of global monetary policy and the prospect of a soft landing among international markets.

• The Fund's holdings in the Financials, Consumer Discretionary, and Materials sectors detracted from the Fund's performance. Conversely, holdings in the Information Technology and Health Care sectors contributed to performance. The Fund’s holdings in Taiwan detracted from performance, while holdings in Korea contributed positively to performance during the period.

Factors Affecting Performance [Text Block]

How did the Fund perform and what affected its performance?

The Investor Class of the Fund returned 18.07% for the twelve months ended October 31, 2024, compared to the MSCI^® EAFE Index (Net) return of 22.97% and the MSCI^® ACWI ex USA Small Cap Index (Net) return of 23.73%.

• The Fund’s strategy of informed momentum investing struggled as investors rotated into lower momentum and weaker quality stocks in the latter part of the twelve-month period with the loosening of global monetary policy and the prospect of a soft landing among international markets.

• The Fund's holdings in the Financials, Consumer Discretionary, and Materials sectors detracted from the Fund's performance. Conversely, holdings in the Information Technology and Health Care sectors contributed to performance. The Fund’s holdings in Taiwan detracted from performance, while holdings in Korea contributed positively to performance during the period.
