This fund actively oversees a portfolio primarily composed of government and corporate debt securities, all denominated in Canadian dollars. It retains the option to allocate up to 40% of its capital to non-Canadian securities. The eligible debt includes both higher-rated (investment-grade) and lower-rated (non-investment-grade) instruments, such as loans and any other debt instruments the portfolio manager deems beneficial for boosting the fund's total return. Bonds are chosen through thorough fundamental research designed to identify overvalued and undervalued segments within the fixed income landscape. When distributing assets across various sectors, significant importance is given to credit quality alongside dynamic yield-curve management. Additionally, ZCPB can commit as much as 30% of its holdings to other investment funds managed by its issuer, or companies affiliated or associated with it.
