| Factors Affecting Performance [Text Block] | What drove fund performance during the past 12 months? High yield bonds strongly advanced in the 12-month period ended May 31, 2024, as a pause in rate hikes, receding recession fears, healthy risk appetite, and favorable technical conditionsa pickup in primary issuance and improved market liquiditysupported performance. Compared with the style-specific ICE BofA US High Yield Constrained Index, the funds strongest relative results were in the media, services, and leisure segments. By credit quality, our selection in the B and BB rating tiers provided meaningful relative contributions. Our underweight to BBs was also beneficial as lower qualities outperformed. The funds off-benchmark allocation to bank loans added relative value as they outperformed high yield bonds for the year. Relative to the style-specific benchmark, the funds weakest results were in the health care, capital goods, and technology and electronics industries. Our selection among CCC rated bonds also detracted. The fund seeks total return and, secondarily, current income by investing primarily in U.S. below investment-grade corporate debt securities. We utilized the markets rally to trim or exit names that we believed to be fully valued and redeployed the proceeds into higher-conviction ideas, selectively taking advantage of stronger primary issuance. We expect more income-like returns from here given tight spread levels. We significantly increased the credit quality of the fund and sought to maintain a current yield advantage versus the index by exchanging lower-coupon COVID-era bonds for higher-coupon paper and increasing bank loan exposure. | |
