The investment seeks to maximize total return. Under normal circumstances, the fund invests substantially all of its assets in the State Street DoubleLine Total Return Tactical Portfolio (the "Portfolio"), a separate series of the SSgA Master Trust with an identical investment objective as the fund. As a result, it invests indirectly through the Portfolio. Under normal circumstances, DoubleLine Capital LP (the "Sub-Adviser" or "DoubleLine") will invest at least 80% of the Portfolio's net assets in a portfolio of fixed income securities of any credit quality. The fund is non-diversified.
