Past performance is not a reliable indicator for future results. All financial investments involve an element of risk. The value of investments may rise and fall so you may get back less than originally invested. Investors should consider the risks, including lower returns, related to currency movements between their investing currency and the portfolio's base currency, if different. Total gross-of-fee returns for the composite (includes both capital appreciation and income) in the currency displayed terms, net of all transaction costs, any withholding taxes and direct expenses, but before management fees, custody and other indirect expenses.

Emerging markets can have less market structure, depth, and regulatory, custodial or operational oversight and greater political, social, and economic instability than developed markets. Investments in small-cap companies can be more volatile than investments in larger companies. The portfolio's performance may be closely tied to the performance of companies in a limited number of sectors and could be more volatile than the performance of less focused portfolios. * Effective 06/30/17, the strategy name has changed from MFS International Small Cap Equity to MFS International Small-Mid Cap Equity.

MFS Investment Management has been independently verified for the periods 1-Jan-1988 through 31-Dec-2016. Verification assesses whether (1) the firm has complied with all the composite construction requirements of the GIPS standards on a firm-wide basis and (2) the firm's policies and procedures are designed to calculate and present performance in compliance with the GIPS standards. Verification does not ensure the accuracy of any specific composite presentation. Total Gross-of-fee returns in USD (includes both capital appreciation and income) are net of transaction costs, withholding taxes and direct expenses, but before management fees, custody and other indirect expenses. Certain institutional accounts hold Canadian trusts subject to custody and other indirect expenses. Certain accounts may be subject to fair valuation as conditions warrant. Typical separate accounts utilize 4:00 PM (London Time) foreign exchange rates; retail products will use rates deemed most appropriate for daily NAV per share calculations. The possibility exists for performance dispersion between otherwise similarly managed accounts and also with the benchmark. Net composite returns are prepared by subtracting from the monthly gross returns one-twelfth of the maximum applicable annual institutional separate account fee. Total returns of the benchmark are provided for each period depicted, expressed in USD. Source of Benchmark Performance: FACTSET.
