TUSB provides segmented exposure to the US fixed income market by actively investing in ultra-short term domestic debt securities with investment grade credit rating. These securities include corporate and government bonds, asset- and mortgage-back securities, preferred stocks, collateralized debt obligations, and other income-producing debt securities. It may also invest a portion in USD-denominated debt of foreign companies. To maintain its ultra-short niche, the fund aims for a dollar-weighted average effective maturity of two years or less. In selecting constituents, the fund uses fundamental and other investment research techniques to assess a securitys value. Since the fund is actively managed, investment decisions are at the discretion of the adviser. TUSB may also utilize derivatives including US treasury future contracts to manage the funds duration and interest risk. The fund seeks a high level of current income.
