*Short positions, unlike long positions, lose value if the underlying asset gains value.
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.
The list of portfolio holdings is as of the date shown and may not represent current or future portfolio composition. This information should not be construed as a recommendation to buy or sell any of the securities mentioned.
This portfolio data has not been audited or adjusted for certain financial statement reclassifications. An audit could potentially result in adjustments to this data. For adjusted holdings information, please refer to the fund's quarterly portfolio holdings and semiannual reports. For audited portfolio holdings information, please refer to the fund's annual report.
A complete list of portfolio holdings for each MFS fund is generally available on mfs.com at the earliest, 19 days after the end of each month. Top 10 portfolio holdings are generally available at the earliest, 11 calendar days after the end of each month.
When posting a fund's top 10 securities holdings, if applicable, for funds with significant investments in both equity and debt instrument securities, the fund's top 10 equity and top 10 debt instrument securities will be made available. In addition, for funds that primarily invest in shares of MFS funds, when posting a fund's top 10 securities holdings, all of the following, as applicable, will be posted all securities positions in shares of MFS funds, top 10 aggregated equity securities contained within fund investments and top 10 aggregated debt instrument securities positions contained within underlying fund investments.
