Factors Affecting Performance [Text Block]
Management’s Discussion of Fund Performance

SUMMARY OF RESULTS
California Municipal Bond Fund (Class I/JCAFX) returned 5.12% for the year ended May 31, 2024. The most significant factors affecting Fund performance during the period included rising municipal bond yields, stronger-than-expected economic growth, and lowered expectations for interest rate cuts by the U.S. Federal Reserve. Sector performance in the municipal market was also a key factor, with high-yield bonds outperforming by a significant margin during the period.

TOP PERFORMANCE CONTRIBUTORS
High-yield municipal bonds | A position in high-yield securities provided a boost to fund performance.
General obligation (GO) bonds | GOs issued by school districts and local governments were key contributors to performance.
Special tax bonds | Bonds financing specific infrastructure projects added value during the period.
TOP PERFORMANCE DETRACTORS
Duration (interest rate sensitivity) | Rising municipal bond yields put downward pressure on municipal bond prices.
Selected hospital bonds | Although the hospital sector performed well overall, several individual holdings in the sector detracted from performance.
