Performance data shown represents past performance and is no guarantee of future results. Investment return and principal value fluctuate so your shares, when sold, may be worth more or less than the original cost; current performance may be lower or higher than quoted.

An investment in the portfolio is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Although the portfolio seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the portfolio.

Important Performance Information

Performance results reflect any applicable expense subsidies and waivers in effect during the periods shown. Without such subsidies and waivers the fund's performance results would be less favorable. All results are historical and assume the reinvestment of dividends and capital gains.

Class A shares ("A") for MFS U.S. Government Cash Reserve Fund and MFS U.S. Government Money Market Fund may be purchased and redeemed at net asset value and have no initial sales charge.

Important Risk Considerations

  • You could lose money by investing in the Fund. Although the Fund seeks to preserve the value of your investment at $1.00 per share, it cannot guarantee it will do so. An investment in the Fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The Fund¿s sponsor has no legal obligation to provide financial support to the Fund, and you should not expect that the sponsor will provide financial support to the Fund at any time. A major increase in interest rates or a decline in the credit quality of an issuer or entity providing credit support, an inactive trading market for money market instruments, or adverse market, economic, political, regulatory, geopolitical, or other conditions could cause the fund's share price to decrease to below $1.00.

  • The fund's performance could be more volatile than the performance of more diversified funds.
