Factors Affecting Performance [Text Block]  

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

Class A shares of the Fund returned 6.78% (unadjusted for sales charges) for the period ended January 31, 2026. The Bloomberg U.S. Aggregate Bond Index returned 6.85% for the same period.

The Fund’s strong total and absolute return for the 12 months ending January 31, 2026, in part reflects positive performance from overweights to credit-sensitive sectors and positioning with respect to interest rates.

The Fund’s performance relative to the Bloomberg U.S. Aggregate Bond Index was supported by both overall security selection and asset allocation. Overweight exposure to risk assets that trade at a higher yield relative to Treasuries was motivated by a relatively stable economic backdrop featuring continued growth and low unemployment. In addition to a sound fundamental picture, the technical environment was also supportive of performance for credit-based assets as attractive all-in yields drove inflows into those sectors. In view of uncertainties around tariffs and inflation, the Fund tactically reduced risk at times to protect against downside outcomes or spread widening. In terms of specific exposures, positive contributions came from risk positioning in investment grade corporate bonds, most notably overweights to the banking/finance, energy, utility and communication subsectors. In addition, within financials, energy and utilities, performance benefited from holdings of securities that were lower in the capital structure or subordinated. An overweight to BBB-rated securities (the lowest investment grade category) across financials, industrials and utilities also proved additive. Overweight exposure to other credit-oriented sectors including collateralized loan obligations, asset-backed securities and commercial mortgage-backed securities contributed as well. Finally, the Fund was positioned to benefit as the Treasury yield curve steepened over the period, while tactical positioning with respect to duration and corresponding interest rate sensitivity allowed the Fund to take advantage as Treasury yields periodically declined. As the yield curve steepened, trades were implemented to take advantage of bonds experiencing price gains as they approach maturity and gravitate towards par value.

There were no material detractors in terms of sector or interest rate positioning.

Factors Affecting Performance [Text Block]  

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

Class C shares of the Fund returned 5.99% (unadjusted for sales charges) for the period ended January 31, 2026. The Bloomberg U.S. Aggregate Bond Index returned 6.85% for the same period.

Factors Affecting Performance [Text Block]  

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

Class S shares of the Fund returned 7.06% for the period ended January 31, 2026. The Bloomberg U.S. Aggregate Bond Index returned 6.85% for the same period.

The Fund’s strong total and absolute return for the 12 months ending January 31, 2026, in part reflects positive performance from overweights to credit-sensitive sectors and positioning with respect to interest rates.

The Fund’s performance relative to the Bloomberg U.S. Aggregate Bond Index was supported by both overall security selection and asset allocation. Overweight exposure to risk assets that trade at a higher yield relative to Treasuries was motivated by a relatively stable economic backdrop featuring continued growth and low unemployment. In addition to a sound fundamental picture, the technical environment was also supportive of performance for credit-based assets as attractive all-in yields drove inflows into those sectors. In view of uncertainties around tariffs and inflation, the Fund tactically reduced risk at times to protect against downside outcomes or spread widening. In terms of specific exposures, positive contributions came from risk positioning in investment grade corporate bonds, most notably overweights to the banking/finance, energy, utility and communication subsectors. In addition, within financials, energy and utilities, performance benefited from holdings of securities that were lower in the capital structure or subordinated. An overweight to BBB-rated securities (the lowest investment grade category) across financials, industrials and utilities also proved additive. Overweight exposure to other credit-oriented sectors including collateralized loan obligations, asset-backed securities and commercial mortgage-backed securities contributed as well. Finally, the Fund was positioned to benefit as the Treasury yield curve steepened over the period, while tactical positioning with respect to duration and corresponding interest rate sensitivity allowed the Fund to take advantage as Treasury yields periodically declined. As the yield curve steepened, trades were implemented to take advantage of bonds experiencing price gains as they approach maturity and gravitate towards par value.

There were no material detractors in terms of sector or interest rate positioning.

Factors Affecting Performance [Text Block]  

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

Institutional Class shares of the Fund returned 6.98% for the period ended January 31, 2026. The Bloomberg U.S. Aggregate Bond Index returned 6.85% for the same period.

The Fund’s strong total and absolute return for the 12 months ending January 31, 2026, in part reflects positive performance from overweights to credit-sensitive sectors and positioning with respect to interest rates.

The Fund’s performance relative to the Bloomberg U.S. Aggregate Bond Index was supported by both overall security selection and asset allocation. Overweight exposure to risk assets that trade at a higher yield relative to Treasuries was motivated by a relatively stable economic backdrop featuring continued growth and low unemployment. In addition to a sound fundamental picture, the technical environment was also supportive of performance for credit-based assets as attractive all-in yields drove inflows into those sectors. In view of uncertainties around tariffs and inflation, the Fund tactically reduced risk at times to protect against downside outcomes or spread widening. In terms of specific exposures, positive contributions came from risk positioning in investment grade corporate bonds, most notably overweights to the banking/finance, energy, utility and communication subsectors. In addition, within financials, energy and utilities, performance benefited from holdings of securities that were lower in the capital structure or subordinated. An overweight to BBB-rated securities (the lowest investment grade category) across financials, industrials and utilities also proved additive. Overweight exposure to other credit-oriented sectors including collateralized loan obligations, asset-backed securities and commercial mortgage-backed securities contributed as well. Finally, the Fund was positioned to benefit as the Treasury yield curve steepened over the period, while tactical positioning with respect to duration and corresponding interest rate sensitivity allowed the Fund to take advantage as Treasury yields periodically declined. As the yield curve steepened, trades were implemented to take advantage of bonds experiencing price gains as they approach maturity and gravitate towards par value.

There were no material detractors in terms of sector or interest rate positioning.

Credit Ratings Selection [Text Block]   The quality ratings represent the highest of Moody’s Investors Service, Inc. (“Moody’s”), Fitch Ratings, Inc. (“Fitch”) or S&P Global Ratings (“S&P”) credit ratings. The ratings of Moody’s, Fitch and S&P represent their opinions as to the quality of the securities they rate.
