Overview

Key features

The objective of Optimum Large Cap Value Fund is to seek long-term growth of capital, and it may also seek income.

Massachusetts Financial Services Company (MFS) aims to provide exposures to companies it believes are undervalued compared to their perceived worth. These companies tend to have stock prices that are low relative to their earnings, dividends, assets, or other financial measures.

Great Lakes Advisors, LLC employs an integrated approach which balances quantitative analysis, fundamental research, and risk management guidelines to identify stocks of companies it believes possess attractive relative valuation and an ability to exceed market expectations.

Performance

The performance quoted represents past performance and does not guarantee future results. Investment return and principal value of an investment will fluctuate so that shares, when redeemed, may be worth more or less than their original cost. Current performance may be lower or higher than the performance quoted.

Total returns may reflect waivers and/or expense reimbursements by the manager and/or distributor for some or all of the periods shown. Performance would have been lower without such waivers and reimbursements.

Returns for less than one year are not annualized.

Performance at NAV assumes that no front-end sales charge applied. Performance at max offer price assumes that a front-end sales charge applied.

Class A shares have a maximum up-front sales charge of 5.75% and are subject to an annual distribution fee.

Index performance returns do not reflect any management fees, transaction costs, or expenses. Indices are unmanaged and one cannot invest directly in an index.

Returns for less than one year are not annualized.

Performance at NAV assumes that no contingent deferred sales charge applied or the investment was not redeemed. Performance at max offer price assumes that a contingent deferred sales charge applied to the extent applicable.

Class C shares redeemed within one year of purchase are subject to a 1.00% contingent deferred sales charge (CDSC). Class C shares are eligible to automatically convert to Class A shares with a lower 12b-1 fee approximately eight years after you buy Class C shares.

Rankings shown are provided by Lipper, Inc., a leading independent analysis service. Rankings and performance for other time periods are available from Lipper.

Past performance is no guarantee of future results.

The Fund offers other share classes, and their performance and rankings may be lower than those of the class shown.

Lipper rankings reflect a fund's historical total return performance, excluding sales charges as applicable, relative to peers as of the above date. The ratings are subject to change every month and are based on equal-rated average of percentile ranks for the total return metrics over 1-, 3-, 5-, and 10-year periods, if applicable. Lipper rankings are not intended to predict future results, and Lipper does not guarantee the accuracy of this information.

Expense waivers may have been in effect for some or all of the periods shown. Performance would have been lower if waivers did not apply or if sales charges were included. Lipper rankings may have been lower if waivers did not apply or if sales charges were included.
