Monthly Standardized Report

Market returns are based on the midpoint of the bid/ask spread at 4 p.m. ET and do not represent the returns an investor would receive if shares were traded at other times. Performance data quoted represents past performance, which is not a guarantee of future results. Investment returns and principal value will fluctuate, and shares, when redeemed, may be worth more or less than their original cost. Current performance may be higher or lower than performance data quoted. After-tax returns reflect the highest federal income tax rate but exclude state and local taxes. Fund performance reflects fee waivers, absent which, performance data quoted would have been lower. After Tax Held and After Tax Sold are based on NAV.
