Top basket holdings are as of the date indicated and may not be representative of the fund's current or future investments. ETF shares are created when a large institutional investor called an Authorized Participant deposits a portfolio of securities into the fund (a "Basket") in exchange for an institutional block of ETF shares (usually 50,000). This is referred to as "in kind" creation because a basket of securities is exchanged for ETF shares rather than using cash. In the case of redemptions, the ETF sponsor returns a basket of securities to the Authorized Participant in exchange for an institutional block of ETF shares. The Basket Holdings is the portfolio of securities that can be exchanged on a daily basis for ETF shares. In some circumstances, cash may be accepted in lieu of some or all of the securities in the Basket.
