FISR Employs a proprietary selection model which incorporates macroeconomic, financial and market data to project fixed income sector returns. Using these forecasts, the model then allocates the weightings of each Fixed Income Sector to construct a portfolio that seeks to maximize expected return. Included fixed income sectors are: (i) securities issued or guaranteed by the U.S. government or its agencies, (ii) inflation protected public obligations of the U.S. Treasury, (iii) U.S. corporate securities, (iv) U.S. mortgage-backed securities, (v) high yield securities, (vi) international government and corporate securities, including emerging markets, (vii) senior secured floating rate bank loans, (viii) floating and variable rate securities, and (ix) cash equivalents. Although FISR employs a model, the fund is actively-managed. Prior to Oct. 31, 2025, the fund did not use the State Street brand reference in the fund name.
