Example
This example is intended to help you compare the cost of investing in the fund with the cost of investing in other mutual funds.
The example assumes that: you invest $10,000 in the fund for the time periods indicated and you redeem your shares at the end of the time periods (unless otherwise indicated); your investment has a 5% return each year; and the funds operating expenses remain the same.
Although your actual costs will likely be higher or lower, under these assumptions your costs would be:

Portfolio Turnover
The fund pays transaction costs, such as commissions, when it buys and sells securities (or turns over its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when shares are held in a taxable account. These transaction costs, which are not reflected in Annual Fund Operating Expenses or in the Example, affect the funds performance.
Principal Investment Strategies
MFS (Massachusetts Financial Services Company, the funds investment adviser) normally invests at least 80% of the funds net assets in equity securities. Equity securities include common stocks, preferred stocks, securities convertible into stocks, equity interests in real estate investment trusts (REITs), and depositary receipts for such securities.
MFS seeks to outperform the MSCI All Country World Index over a full market cycle with a targeted volatility of at least 30% less than the volatility of the MSCI All Country World Index. There is no assurance that the fund will outperform the MSCI All Country World Index or meet this target volatility over the long term or for any year or period of years. Volatility is measured by the standard deviation of monthly returns. Volatility generally measures how much the funds returns have varied over a specified time period. A higher volatility means that the funds returns have varied more over time while a lower volatility means the funds returns have varied less over time. It is expected that the fund will generally underperform the equity markets during strong, rising equity markets.
In selecting investments for the fund, MFS is not constrained to any particular investment style. MFS may invest the funds assets in the stocks of companies it believes to have above average earnings growth potential compared to other companies (growth companies), in the stocks of companies it believes are undervalued compared to their perceived worth (value companies), or in a combination of growth and value companies.
MFS may invest the funds assets in companies of any size.
MFS may invest the funds assets in U.S. and foreign securities, including emerging market securities.
MFS may invest a large percentage of the funds assets in issuers in a single country, a small number of countries, or a particular geographic region.
MFS uses a bottom-up approach to buying and selling investments for the fund.
Investments are selected based on fundamental and quantitative analysis of approximately 3,000 global issuers
.
MFS eliminates approximately 30% or more of the most volatile equity securities based on historical volatility as potential investments for the fund. MFS may continue to hold and to consider for further investment equity securities whose historical volatility increases above the 30% threshold after purchase. From the remaining issuers in the funds investment universe, MFS then constructs the portfolio considering the fundamental and quantitative analysis as well as issuer, sector, industry, volatility and other constraints.
Principal Risks
As with any mutual fund, the fund may not achieve its objective and/or you could lose money on your investment in the fund. An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency.
The principal risks of investing in the fund are:
Stock Market/Company Risk:
Stock markets are volatile and can decline significantly in response to issuer, market, economic, industry, political, regulatory, geopolitical, and other conditions, as well as to investor perceptions of these conditions. The price of an equity security can decrease significantly in response to these conditions, and these conditions can affect a single issuer or type of security, issuers within a broad market sector, industry or geographic region, or the market in general.
Investment Strategy Risk
: The funds strategy to invest in equity securities with historically lower volatility may not produce the intended results if lower volatility equity securities do not outperform the MSCI All Country World Index, if the historical volatility of an equity security is not a good predictor of the future volatility of that equity security, and/or if equity securities held by the fund become more volatile than their historical volatility. It is expected that the fund will generally underperform the equity markets during strong, rising equity markets.
Foreign and Emerging Markets Risk:
Exposure to foreign markets, especially emerging markets, through issuers or currencies can involve additional risks relating to market, economic, industry, political, regulatory, geopolitical, and other conditions. These factors can make foreign investments, especially those in emerging markets, more volatile and less liquid than U.S. investments. In addition, foreign markets can react differently to these conditions than the U.S. market. Emerging markets can have less developed markets, greater custody and operational risk, less developed legal, regulatory, and accounting systems, and greater political, social, and economic instability than developed markets.
Currency Risk:
The value of foreign currencies relative to the U.S. dollar fluctuates in response to market, economic, industry, political, regulatory, geopolitical, and other conditions, and a decline in the value of a foreign currency versus the U.S. dollar reduces the value in U.S. dollars of investments denominated in that foreign currency.

MFS Low Volatility Global Equity Fund
Geographic Concentration Risk:
The funds performance could be closely tied to the market, currency, economic, political, regulatory, geopolitical, and other conditions in the countries or regions in which the fund invests and could be more volatile than the performance of more geographically-diversified funds.
Investment Selection Risk:
MFS investment analysis, its development and use of quantitative models, and its selection of investments may not produce the intended results and/or can lead to an investment focus that results in the fund underperforming other funds with similar investment strategies and/or underperforming the markets in which the fund invests.
Liquidity Risk:
It may not be possible to sell certain investments, types of investments, and/or segments of the market at any particular time or at an acceptable price.
Performance Information
The bar chart and performance table are not included because the fund has not had a full calendar year of operations.

If your shares are held in a taxable account, the funds distributions will be taxed to you as ordinary income and/or capital gains. If your shares are held in a tax-deferred account, you will generally be taxed only upon withdrawals from the account.
Payments to Broker/Dealers and Other Financial Intermediaries
If you purchase shares of the fund through a broker/dealer or other financial intermediary (such as a bank), the fund, MFS, and MFS affiliates may pay the financial intermediary for the sale of shares of a fund and/or the servicing of shareholder accounts. These payments may create a conflict of interest by influencing your broker/dealer or other financial intermediary and your salesperson to recommend the fund over another investment. Ask your financial intermediary or visit your financial intermediarys Web site for more information.
