MassMutual Small Cap Growth Equity Fund Class R3 MSGNX Strategy

The investment seeks long-term capital appreciation. The fund normally invests at least 80% of its net assets (plus the amount of any borrowings for investment purposes) in the equity securities of companies whose market capitalizations at the time of purchase are within the market capitalization range of companies included in the Russell 2000® Index or the S&P SmallCap 600 Index. While most assets typically will be invested in common stocks of U.S. companies, the fund also may invest up to 20% of its total assets in foreign securities, including emerging market securities.
