Administrative Shares - With Sales Charge (POP) (%)
Performance data quoted represents past performance, which does not guarantee future results. Current performance may be lower or higher than the figures shown. Principal value and investment returns will fluctuate, and investors' shares, when redeemed, may be worth more or less than the original cost. Performance would have been lower if fees had not been waived in various periods. Total returns assume the reinvestment of all distributions and the deduction of all Fund expenses. Returns with sales charge reflect a deduction of the stated maximum sales charge. Returns without sales charge would have been lower had sales charges been reflected. An investor cannot invest directly in an index, and unmanaged index returns do not reflect any fees, expenses or sales charges. Returns for periods of less than one year are not annualized.
