Important Characteristics Information

Portfolio characteristic data are based on unaudited net assets.

The portfolio is actively managed, and current holdings may be different.

Portfolio characteristics are based on equivalent exposure, which measures how a portfolio's value would change due to price changes in an asset held either directly or, in the case of a derivative contract, indirectly. The market value of the holding may differ.

*Short positions, unlike long positions, lose value if the underlying asset gains value.

This publication is authorized for distribution only when preceded or accompanied by a prospectus, or summary prospectus, for the portfolio being offered. Consider the fund's investment objectives, risks, charges and expenses. Contact MFS or view online. Read it carefully.
