| Factors Affecting Performance [Text Block] | What drove fund performance during the past 12 months? Leveraged loans strongly advanced and outpaced most fixed income alternatives in the year ended May 31, 2024, amid growing expectations that the Federal Reserve would keep interest rates higher for longer. The resilient economy, investors healthy risk appetite, and favorable technical conditions also supported the asset classs performance. Compared with the style-specific Morningstar LSTA Performing Loan Index, credit selection in the services sector aided relative performance, driven by our holdings in Ultimate Kronos Group and Ascend Learning. Asurion was a leading contributor in the wireless communications sector. Its dominant market position, solid credit profile, and near-term revenue visibilityas well as an attractive couponsupport our conviction. Selection among cable operators detracted, largely due to Altice France. In March, the company aggressively moved pending asset sales to an unrestricted subsidiary and threatened to withhold them from creditors unless they took a haircut to their claims. Our conservative positioning relative to the style-specific benchmark held back gains as loans from several fundamentally challenged issuers we did not own, such as Air Medical, rallied in the strong performance environment. The fund seeks high current income and some capital appreciation. Over the past year, we positioned the fund with a bias for discounted paper with shorter-dated maturities from higher-conviction issuers. Greater visibility on the trajectory of short-term interest rates and a high degree of confidence that issuers would be able to access capital markets and refinance the loans 12 to 24 months ahead of maturity supported our participation in these deals. | |
