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. For the period from the funds commencement of operations on September 15, 2011 to the funds fiscal year end of July 31, 2012, the funds portfolio turnover rate was 75% of the average value of its portfolio.
Principal Investment Strategies
MFS (Massachusetts Financial Services Company, the funds investment adviser) normally invests at least 80% of the funds net assets (i) in debt instruments of issuers that are tied economically to emerging market countries and denominated in local currencies and (ii) in derivative instruments with similar economic characteristics to these instruments. Emerging market countries include countries located in Latin America, Asia, Africa, the Middle East, and developing countries of Europe, primarily Eastern Europe.
Debt instruments include corporate bonds, U.S. Government securities, foreign government securities, asset-backed securities, and other obligations to repay money borrowed.
MFS generally focuses on foreign government and government-related debt instruments, but may also invest in corporate debt instruments.
MFS may invest up to 100% of the funds assets in less than investment grade quality debt instruments (lower quality debt instruments).
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.
The fund is a non-diversified fund. This means that MFS may invest a relatively large percentage of the funds assets in a single issuer or a small number of issuers.
While MFS may use derivatives for any investment purpose, to the extent MFS uses derivatives, MFS expects to use derivatives primarily to increase or decrease exposure to a particular market, segment of the market, or security, to increase or decrease interest rate or currency exposure, or as alternatives to direct investments. Derivatives include futures, forward contracts, options, structured securities, inverse floating rate instruments, and swaps.
MFS generally uses a top-down approach to buying and selling investments for the fund. MFS allocates the funds assets across countries and selects investments primarily based on fundamental economic and financial analysis. Quantitative models that systematically evaluate economic and financial factors may also be considered. MFS may also use a bottom-up investment approach, particularly for corporate debt instruments, selecting investments based on fundamental analysis of individual instruments and their issuers.
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:
Interest Rate Risk:
The price of a debt instrument falls when interest rates rise and rises when interest rates fall. Instruments with longer maturities, or that do not pay current interest, are more sensitive to interest rate changes.
Credit Risk:
The price of a debt instrument depends, in part, on the credit quality of the issuer, borrower, counterparty, or underlying collateral or assets and the terms of the instrument. The price of a debt instrument can decline in response to changes in the financial condition of the issuer, borrower, counterparty, or underlying collateral or assets, or changes in specific or general market, economic, industry, political, regulatory, geopolitical, or other conditions.
Lower quality debt instruments (commonly referred to as high yield securities or junk bonds) can involve a substantially greater risk of default or can already be in default, and their values can decline significantly. Lower quality debt instruments are regarded as having predominantly speculative characteristics. Lower quality debt instruments tend to be more sensitive to adverse news about the issuer, or the market or economy in general, than higher quality debt instruments.
Foreign and Emerging Markets Risk:
Exposure to foreign markets, especially emerging markets, through issuers or currencies can involve additional risks relating to market, economic, political, regulatory, geopolitical, or 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, political, regulatory, geopolitical or 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.

Geographic Concentration Risk:
The funds performance could be closely tied to the market, currency, economic, political, regulatory, geopolitical, or 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.
Non-Diversification Risk:
Because MFS may invest a relatively large percentage of the funds assets in a single issuer or small number of issuers, the funds performance could be closely tied to the value of that one issuer or issuers, and could be more volatile than the performance of diversified funds.
Derivatives Risk:
Derivatives can be highly volatile and involve risks in addition to the risks of the underlying indicator(s) on which the derivative is based. Gains or losses from derivatives can be substantially greater than the derivatives original cost. Derivatives can involve leverage.
Leveraging Risk:
Leverage involves investment exposure in an amount exceeding the initial investment. Leverage can cause increased volatility by magnifying gains or losses.
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.
Counterparty and Third Party Risk:
Transactions involving a counterparty or third party other than the issuer of the instrument are subject to the credit risk of the counterparty or third party, and to the counterpartys or third partys ability to perform in accordance with the terms of the transaction.
Investment Selection Risk:
MFS investment analysis 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.
Performance Information

Taxes
If your shares are held in a taxable account, the funds distributions are taxable to you, and will be taxed as ordinary income and/or capital gains.
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.
