About the Best Company Lipper Award

In order to qualify for consideration, fund firms must meet the following cumulative criteria:

• Funds registered for sale in the respective country as of the end of the calendar year of the respective evaluation year.
• At least 36 months of performance history as of the end of the calendar year of the respective evaluation year.
• Lipper Global classifications with at least ten distinct portfolios based on the primary share class definition, excluding residual classifications, institutional, private, closed-end, exchange traded, insurance and linked funds.
• Asset classes: equity, bond, and mixed-asset except for Absolute Return funds where money market and other fund asset types are considered as well.

Fund groups with at least five equity, five bond, and three mixed asset funds are eligible for an overall group award. An overall group award will be given to the group with the lowest average decile ranking of its respective asset class results based on the methodology described above. In cases of identical results, the lower average percentile rank will determine the winner. An overall group award will be given to the best large and small group separately. Small groups will need to have at least three equity, three bond, and three mixed-asset funds. No overall group awards are handed out if there are less than three competing companies. Overall group awards are given to the company that is responsible for establishing the fund by appointing the fund management company, promoting and/or distributing the fund, the brand of the fund and the product range.

About the Individual Fund Awards

Classification averages are calculated with all eligible share classes for each eligible classification. The calculation periods extend over 36, 60, and 120 months. The highest Lipper Leader for Consistent Return (Effective Return) value within each eligible classification determines the fund classification winner over three, five, or ten years. Fund classification awards are given to the company that has the day-to-day responsibility of investing and monitoring the assets under management within the fund’s portfolio in order to achieve the investment objectives of the fund.

Important Risk Information:

The fund may not achieve its objective and/or you could lose money on your investment in the fund. Stock markets and investments in individual stocks are volatile and can decline significantly in response to issuer, market, economic, political, regulatory, geopolitical, and other conditions.

Investments in debt instruments may decline in value as the result of increases in interest rates, declines in the credit quality of the issuer, borrower, counterparty or underlying collateral, or changes in economic, political, issuer-specific, or other conditions. Certain types of debt instruments can be more sensitive to these factors and therefore more volatile. Investments in foreign markets through issuers or currencies can involve greater risk and volatility than U.S. investments because of adverse market, economic, political, regulatory, geopolitical, or other conditions. Emerging markets can have less market structure, depth, and regulatory oversight and greater political, social, and economic instability than developed markets.

Before investing, consider the fund's investment objectives, risks, charges, and expenses. For a prospectus, or summary prospectus if available, containing this and other information, contact your investment professional or view online at mfs.com. Please read it carefully.
