Factors Affecting Performance [Text Block]

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

Class A shares of the Fund returned 7.00% (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 ICE BofA U.S. High Yield Index, returned 7.23%.

The Fund’s relative performance (compared to the ICE BofA U.S. High Yield Index) was hurt by an underweight in the outperforming CCC rated category. On the other hand, an overweight in B rated bonds — together with strong security selection in the category — contributed positively.

Sector allocation detracted from results, largely due to underweights in outperforming sectors such as media and entertainment, finance, and consumer cyclicals. Overweights in the outperforming metals and mining, energy exploration and production, and pharmaceuticals sectors contributed.

Security selection made a positive contribution to performance, with the best results occurring in the midstream energy and electric utilities sectors. Selection in the media and wireless telecommunications sectors detracted.

An underweight in the energy infrastructure company New Fortress Energy* was a top contributor at the individual security level. The bonds weakened on concerns that the proceeds of asset sales would be insufficient to meet the company’s liquidity needs, leading to downgrades to its credit rating. The Fund also benefited from an overweight in the engineered processing equipment and systems manufacturer Hillenbrand (1.0%), which announced it was exploring strategic options, including a potential sale. An overweight in the Japanese internet company Rakuten Group (1.0%), was a further contributor. The bonds gained in price after earnings in the company’s mobile segment moved into positive territory.

An overweight in the bonds of the commodity chemical manufacturer Tronox (0.2%) was a notable detractor. The company reduced full year earnings and free cash flow guidance, and it received a credit downgrade due to its continued operational challenges. Underweights in Warnermedia Holdings, Inc. (0.5%), Discovery Communications LLC (0.5%) and iHeartCommunications* detracted, as well.

Percentages in parentheses are based on the Fund’s net assets as of September 30, 2025.

* Not held at September 30, 2025.
