Morningstar Overall Ratings as of March 31, 2008, Class A shares. Morningstar Ratings are based on risk-adjusted performance. The Overall Morningstar Rating™ is based on the weighted average of the performance figures associated with its 3-, 5- and 10-year (if applicable) Morningstar Rating metrics. For each fund with at least a three-year history, a Morningstar Rating is based on a Risk-Adjusted Return measure that accounts for variation in a fund's monthly historical performance (reflecting sales charges and redemption fees), placing more emphasis on downward variations and rewarding consistent performance. Within each asset class, the top 10%, the next 22.5%, 35%, 22.5%, and the bottom 10% receive 5, 4, 3, 2, or 1 star, respectively. Ratings may vary among share classes and are based on historical total returns, which are not indicative of future results. Keep in mind, a high relative ranking does not always mean the fund achieved a positive return during the period. The following copyright pertains only to the Morningstar information.

A word about risk
Stocks can be volatile and can decline due to adverse issuer, political, regulatory, or economic conditions. This nondiversified fund may be concentrated in a particular industry or sector causing the fund's performance to depend more heavily on the performance of an industry or sector; therefore, performance may be more volatile than the market. Please see the prospectus for further information on these and other risk considerations.

Before investing, consider the fund's investment objectives, risks, charges, and expenses. For a prospectus containing this and other information, contact MFS or view online. Read it carefully.

You should check with your home office for your firm's list of approved MFS products. Be sure to consider your client's financial needs, goals, and risk tolerance before making any investment recommendations.
