T. Rowe Price Corporate Income Fund 

The T. Rowe Price Corporate Income fund primarily allocates a substantial portion—at least 80% of its total assets (including any capital obtained through borrowing)—into corporate debt instruments. While its portfolio is predominantly composed of investment-grade fixed-income securities, it maintains the flexibility to incorporate a limited allocation of lower-rated bonds, often referred to as high-yield or 'junk' bonds. Beyond corporate debt, the fund is also permitted to invest in other security types, strategically aiming to enhance income generation and foster capital appreciation.
