State Street Aggregate Bond Index Fund Class I SSFDX

The investment seeks to provide investment results that, before fees and expenses, correspond generally to the price and yield performance of the Bloomberg U.S. Aggregate Bond Index that tracks the U.S. dollar denominated investment grade bond market over the long term. Under normal circumstances, the fund generally invests substantially all, but at least 80%, of its net assets (plus borrowings, if any) in securities comprising the index or in securities that the Adviser determines have economic characteristics that are comparable to the economic characteristics of securities that comprise the index.
