INVESTMENT OBJECTIVES

SSgA Target Retirement 2050 Non-Lending Series Fund – Class A

The Fund seeks an investment return that approximates, as closely as practicable, before expenses, the performance of a custom benchmark index (the “Index”) over the long term, while providing participants the ability to purchase and redeem units on an “as of” basis. In seeking to accomplish this investment objective, the Fund may invest directly or indirectly in securities and other instruments, including in other pooled investment vehicles sponsored or managed by, or otherwise affiliated with the Trustee (“Commingled Funds”). As of the date of this Fund Declaration, the Trustee intends to invest in the following Commingled Funds over the course of the Fund’s life cycle, as more fully detailed in the Strategy Disclosure Document:

SSgA Global All Cap Equity Ex-U.S. Index Non-Lending Series Fund

SSgA Global Equity Ex-U.S. Index Non-Lending Series Fund

SSgA Russell Small Cap Index Non-Lending Series Fund

SSgA S&P 500 Non-Lending Series Fund

SSgA S&P MidCap Index Non-Lending Series Fund

SSgA U.S. Bond Index Non-Lending Series Fund

SSgA U.S. Inflation Protected Bond Index Non-Lending Series Fund

SSgA U.S. Long Government Bond Index Non-Lending Series Fund

SSgA Tuckerman Global Real Estate Securities Index Non-Lending Series Fund

SSgA U.S. High Yield Bond Index Non-Lending Series Fund

SSgA U.S. Short-Term Government/Credit Bond Index Non-Lending Series Fund

Due to the uncertainty in all investments, there can be no assurance that the Fund will achieve its investment objective.
