Factors Affecting Performance [Text Block]

How did the Fund perform last year and what affected its performance?

The A Class of the Fund returned -6.15% (with sales charges) and -0.42% (without sales charges) for the twelve months ended June 30, 2024, compared to the S&P 500 Index return of 24.56%.

• Overall market performance during the period was narrowly driven by megacap growth companies as interest rates remained higher for longer than anticipated, which hindered the Fund’s investment strategy of investing in transformational innovation companies.

• The Fund’s investments in the capital markets industry materially helped performance for the period. Conversely, its investments in the health care providers & services and health care equipment and supplies industries materially detracted from performance.

Factors Affecting Performance [Text Block]

How did the Fund perform last year and what affected its performance?

The A Class of the Fund returned 6.58% (with sales charges) and 13.05% (without sales charges) for the twelve months ended June 30, 2024, compared to the S&P 500 Index return of 24.56% and the Russell 3000 Value Index return of 12.93%.

• Over the trailing twelve months the market environment has been mixed for the sub-advisor’s investment style of long-term investing in stocks that were recent spinoffs, reorganizations, and misunderstood contrarian situations through an intrinsic value approach.

• Stocks held in the Fund with exposure to the Artificial Intelligence theme have benefited performance significantly.

• The Fund’s investments in smaller market cap stocks where the sub-advisor sees long-term intrinsic value opportunities have been challenged by the higher interest rate environment.

• The Fund’s performance was mainly driven by the sub-advisor’s securities selection decisions in the Information Technology and the Communication Services sectors, which contributed positively to performance, while securities selection in the Industrials sector detracted from performance.

• The S&P 500 Index TR has replaced the Russell 3000 Index since the last Shareholder Report to comply with a new regulatory requirement.

Factors Affecting Performance [Text Block]

How did the Fund perform last year and what affected its performance?

The A Class of the Fund returned -7.91% (with sales charges) and -2.26% (without sales charges) for the twelve months ended June 30, 2024, compared to the S&P 500 Index return of 24.56% and the Russell 2500 Value Index return of 11.24%.

• Over the trailing twelve months the market environment has been challenging for the sub-advisor’s investment style of long-term investing in stocks that were recent spinoffs, reorganizations, and misunderstood contrarian situations through an intrinsic value approach.

• In particular, higher interest rates contributed to underperformance by sub-advisor’s concentrated investments in complex situations.

• The sub-advisor’s security selection in the Materials and the Consumer Discretionary sectors materially detracted from Fund performance, while security selection in the Information Technology sector contributed positively to performance.

• An overweight allocation to the Communication Services sector and an underweight allocation to the Financials sector detracted from performance.

• The S&P 500 Index TR has replaced the Russell 2500^® Index since the last Shareholder Report to comply with a new regulatory requirement.

Factors Affecting Performance [Text Block]

How did the Fund perform last year and what affected its performance?

The C Class of the Fund returned -4.02% (with sales charges) and -3.02% (without sales charges) for the twelve months ended June 30, 2024, compared to the S&P 500 Index return of 24.56% and the Russell 2500 Value Index return of 11.24%.

• In particular, higher interest rates contributed to underperformance by sub-advisor’s concentrated investments in complex situations.

• An overweight allocation to the Communication Services sector and an underweight allocation to the Financials sector detracted from performance.

• The S&P 500 Index TR has replaced the Russell 2500^® Index since the last Shareholder Report to comply with a new regulatory requirement.

Factors Affecting Performance [Text Block]

How did the Fund perform last year and what affected its performance?

The R5 Class of the Fund returned -1.94% for the twelve months ended June 30, 2024, compared to the S&P 500 Index return of 24.56% and the Russell 2500 Value Index return of 11.24%.

• In particular, higher interest rates contributed to underperformance by sub-advisor’s concentrated investments in complex situations.

• An overweight allocation to the Communication Services sector and an underweight allocation to the Financials sector detracted from performance.

• The S&P 500 Index TR has replaced the Russell 2500^® Index since the last Shareholder Report to comply with a new regulatory requirement.

Factors Affecting Performance [Text Block]

How did the Fund perform last year and what affected its performance?

The Investor Class of the Fund returned 7.50% for the twelve months ended June 30, 2024, compared to the Bloomberg U.S. Aggregate Bond Index return of 2.63% and the ICE BofA U.S. 3-Month Treasury Bill Index return of 5.40%.

• The Fund demonstrated attractive performance during the period as its hedged convertible bond strategy capitalized on interest rates that remained elevated, due to the Federal Reserve Bank’s continued narrative of ‘higher-for-longer’ rates, and income was a significant source of total return for the Fund.

• The Fund’s short duration and generally low volatility also benefited performance.

• The Fund’s holdings were diversified across sectors and industries with no individual position having a material impact on performance.

• Financials, Health Care, and Information Technology were the Fund’s largest sector exposures.

Factors Affecting Performance [Text Block]

How did the Fund perform last year and what affected its performance?

The A Class of the Fund returned 4.56% (with sales charges) and 7.30% (without sales charges) for the twelve months ended June 30, 2024, compared to the Bloomberg Global-Aggregate Total Return Index Value Hedged USD return of 4.20% and the ICE BofA 1-3 Year U.S. Corporate Index return of 6.01%.

• The Fund’s lower-duration investments benefited during the period as interest rates rose.

• The Fund held a variety of exposures across credit sectors that the sub-advisor deemed to offer attractive yield, and most sectors contributed positively to total returns.

• Investments in the Financials sector generated the largest contribution to the Fund’s return, followed by selections in the Investment Grade Corporate Bonds sector.

• The Bloomberg Global-Aggregate Total Return Index Value Hedged USD has been added since the last Shareholder Report to comply with a new regulatory requirement.
