7 N Stock: Stock markets and investments in individual stocks are volatile and can decline significantly in response to or investor perception of, issuer, market, economic, industry, political, regulatory, geopolitical, environmental, public health, and other conditions. n Bond: Investments in debt instruments may decline in value as the result of, or perception of, declines in the credit quality of the issuer, borrower, counterparty, or other entity responsible for payment, 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. In addition, debt instruments entail interest rate risk (as interest rates rise, prices usually fall).

8 Therefore, the portfolio's value may decline during rising rates. Portfolios that consist of debt instruments with longer durations are generally more sensitive to a rise in interest rates than those with shorter durations. At times, and particularly during periods of market turmoil, all or a large portion of segments of the market may not have an active trading market. As a result, it may be difficult to value these investments and it may not be possible to sell a particular investment or type of investment at any particular time or at an acceptable price. The price of an instrument trading at a negative interest rate responds to interest rate changes like other debt instruments; however, an instrument purchased at a negative interest rate is expected to produce a negative return if held to maturity.

9 N International: Investments in foreign markets can involve greater risk and volatility than investments because of adverse market, currency, economic, industry, political, regulatory, geopolitical, or other conditions. n Underlying Funds: MFS' strategy of investing in underlying funds exposes the fund to the risks of the underlying funds. Each underlying fund pursues its own objective and strategies and may not achieve its objective. In addition, shareholders of the fund will indirectly bear the fees and expenses of the underlying funds. n Please see the prospectus for further information on these and other risk and vendor disclosuresStandard & Poor's 500 Stock index - a market capitalization -weighted index of 500 widely held equity securities, designed to measure broad equity performance.
