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.
