Factors Affecting Performance [Text Block]

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

Class A shares of the Fund returned 5.02% (unadjusted for sales charges) for the period ended September 30, 2025. The Fund's broad-based index, the Bloomberg U.S. Aggregate Bond Index, returned 2.88% for the same period, while the Fund's additional, more narrowly based index, the Bloomberg 1-3 Year Government/Credit Index, returned 4.12%.

The Fund’s positive absolute performance for the 12 months was supported as the US Treasury yield curve steepened as investors anticipated lower short-term rates from the US Federal Reserve (Fed).

The Fund’s tactical shifts with respect to portfolio duration and corresponding interest rate sensitivity proved additive. In this vein, we were cautious in adding interest rate exposure when we viewed the market’s Fed rate cut projections as overly optimistic, while becoming more constructive as expectations moved towards pricing in fewer moves than our forecast. In addition, as the yield curve assumed a more normal upward sloping shape, we positioned the Fund to benefit from yield declines and corresponding price increases on bonds as they rolled down toward their maturity dates. In terms of sector exposures, we took advantage of various headlines which drove episodic spread widening to position the Fund opportunistically in investment grade corporate bonds, adding meaningfully to performance as we avoided credit issues. Finally, holdings of securitized assets provided strong performance highlighted by overweight exposure to consumer debt within asset-backed and mortgage-backed securities. Allocations to commercial mortgage-backed securities and collateralized loan obligations were also additive.

Positioning within the Fund’s Treasury allocation was a slight detractor as we were underweight the two-year segment of the curve which benefited the most from declining yields.

Factors Affecting Performance [Text Block]

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

Class C shares of the Fund returned 4.24% (unadjusted for sales charges) for the period ended September 30, 2025. The Fund's broad-based index, the Bloomberg U.S. Aggregate Bond Index, returned 2.88% for the same period, while the Fund's additional, more narrowly based index, the Bloomberg 1-3 Year Government/Credit Index, returned 4.12%.

The Fund’s positive absolute performance for the 12 months was supported as the US Treasury yield curve steepened as investors anticipated lower short-term rates from the US Federal Reserve (Fed).

Positioning within the Fund’s Treasury allocation was a slight detractor as we were underweight the two-year segment of the curve which benefited the most from declining yields.

Factors Affecting Performance [Text Block]

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

Class R6 shares of the Fund returned 5.39% for the period ended September 30, 2025. The Fund's broad-based index, the Bloomberg U.S. Aggregate Bond Index, returned 2.88% for the same period, while the Fund's additional, more narrowly based index, the Bloomberg 1-3 Year Government/Credit Index, returned 4.12%.

The Fund’s positive absolute performance for the 12 months was supported as the US Treasury yield curve steepened as investors anticipated lower short-term rates from the US Federal Reserve (Fed).

Positioning within the Fund’s Treasury allocation was a slight detractor as we were underweight the two-year segment of the curve which benefited the most from declining yields.

Factors Affecting Performance [Text Block]

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

Institutional Class shares of the Fund returned 5.38% for the period ended September 30, 2025. The Fund's broad-based index, the Bloomberg U.S. Aggregate Bond Index, returned 2.88% for the same period, while the Fund's additional, more narrowly based index, the Bloomberg 1-3 Year Government/Credit Index, returned 4.12%.

The Fund’s positive absolute performance for the 12 months was supported as the US Treasury yield curve steepened as investors anticipated lower short-term rates from the US Federal Reserve (Fed).

Positioning within the Fund’s Treasury allocation was a slight detractor as we were underweight the two-year segment of the curve which benefited the most from declining yields.

Performance Past Does Not Indicate Future [Text]

The Fund's past performance is not a good predictor or guarantee of the Fund's future performance.
