Fund profile

As filed in the prospectus · 2025 Q3

The funds investment objective is to seek capital appreciation.

Strategy · summarised

The fund invests the majority of its assets in other MFS mutual funds rather than holding securities directly, selecting underlying funds based on their classifications, historical risk, and performance to achieve diversification across market capitalizations, investment styles, and geographies within international markets. Because the fund's returns depend on the performance of the underlying funds chosen, performance will reflect both the adviser's selection decisions and the results of those underlying funds.

These classes hold the same portfolio, so the 7.65pp spread over 5 years is the cost difference between them — roughly 1.53pp a year — not a difference in what they own.

Cumulative return· Jun 2023 – Apr 2026

May 2026 has been filed since the trailing figures were struck, so it is not in the table above or the curve — every figure here shares one cut-off, which is what makes them comparable with other funds.
