Under typical market conditions, this fund commits a minimum of 80% of its overall assets to fixed-income instruments designed to generate income. A core component of its portfolio strategy involves allocating at least 50% of its holdings to debt securities rated as investment-grade. Furthermore, it has the discretion to invest up to 50% of its portfolio in non-investment-grade debt. The fund's managers generally opt to sell a security if its yield-to-price relationship no longer sufficiently offsets its risk profile, or if a reallocation across sectors is deemed appropriate due to shifts in relative market value.
