American Funds The Bond Fund of America® Class 529-A 

The fund's core strategy involves a strong emphasis on fixed-income investments, committing at least 80% of its capital to bonds and various debt instruments, with the flexibility to use derivatives for such exposure. Moreover, a significant segment of the portfolio, no less than 60%, is dedicated to high-quality debt securities. These securities must meet stringent credit criteria, specifically holding a rating of at least A3 or A- from credit rating agencies recognized and designated by the fund's investment adviser, or, alternatively, to unrated debt instruments that the adviser assesses as having comparable financial soundness. This minimum 60% threshold can also be fulfilled through investments in U.S. government securities, money market instruments, and highly liquid assets like cash or cash equivalents.
