PIMCO Credit Opportunities Bond Fund 

This fund commits a significant portion—at least 80%—of its capital to a broad selection of fixed-income securities that mature at different times. To gain exposure to these instruments, it also has the flexibility to use financial derivatives such as forwards, options, futures contracts, and swap agreements. The portfolio is designed to include both high-quality, investment-grade debt and riskier, high-yield bonds (often termed 'junk bonds'). However, there's a strict limit: no more than 50% of the fund's total assets can be invested in securities rated below B- by Moody's, or those holding an equivalent rating from S&P or Fitch. Should a security be unrated, PIMCO will determine if its credit quality is comparable to this threshold.
