ETF shares are bought and sold on an exchange at market prices rather than NAV and may trade at a premium or discount to NAV. Investors may pay more than NAV when buying shares and receive less than NAV when selling shares. Brokerage commissions and other trading costs may reduce returns. Shares of the ETFs are not redeemable with the ETF other than in creation unit aggregations. There can be no assurance that an active trading market for the ETF's shares will develop or be maintained.
