Portfolio Turnover [Heading] Portfolio Turnover
Portfolio Turnover [Text Block]

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual Fund operating expenses or in the example, affect the Fund’s performance. This rate excludes the value of the portfolio securities received or delivered as a result of in-kind creations or redemptions of the Shares. The Fund is newly organized, and as of the date of this Prospectus, has not yet commenced operations.
