Performance is shown on a total return basis (i.e., with gross income reinvested, where applicable). Cumulative return is the aggregate amount that an investment has gained or lost over time. Annualized return is the average return gained or lost by an investment each year over a given time period.

The performance data quoted represents past performance. Past performance does not guarantee future results. The investment return and principal value of an investment will fluctuate so that an investor's shares, when sold or redeemed, may be worth more or less than their original cost and current performance may be lower or higher than the performance quoted. High short-term performance, when observed, is unusual and investors should not expect such performance to be repeated.

Shares of ETFs are bought and sold at market price (not NAV) and are not individually redeemed from the Fund. Brokerage commissions will reduce returns. 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. Indices are unmanaged and do not include the effect of fees, expenses, or sales charges. One
