Investment approach
The investment seeks to provide current income.
Under normal circumstances, the fund invests at least 80% of its net assets, plus any borrowings for investment purposes, in investments designed to track the Bloomberg US Aggregate Index (the "index"). The index is composed of investment grade, fixed-rate debt issues with maturities of one year or more, including government securities, corporate securities, and asset-backed and mortgage-backed securities (securitized products).

In situations where the net and gross fund expense figures are different, the investment manager has contractually agreed to limit the investment option's expense. Differences may also be shown due to the investment manager choosing to pay certain expenses that would normally be payable by the fund. The gross fund expense figure does not reflect any waivers or caps on the mutual fund. Performance shown reflects the application of net expenses of the fund.
