Performance data quoted represents past performance and is no guarantee of future results. Investment return and principal value of an investment will fluctuate so that an investor’s shares, when redeemed, may be worth more or less than the original cost. Current performance may be lower or higher than the performance data quoted. Returns for periods of less than one year are not annualized.


The market price returns are based on the official closing price of an ETF share or, if the official closing price isn’t available, the midpoint between the national best bid and national best offer (“NBBO”) as of the time the ETF calculates current NAV per share, and do not represent the returns you would receive if you traded shares at other times. NAVs are calculated using prices as of 4:00 PM Eastern Time. The first trading date is typically several days after the fund inception date. Therefore, NAV is used to calculate market returns prior to the first trade date because there is no bid/ask spread until the fund starts trading.
