Expense Example Narrative [Text Block]

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. This example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your Shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain at current levels. This example does not include the brokerage commissions that investors may pay to buy and sell Shares.

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

The Fund pays transaction costs, such as commissions, when it purchases and sells securities (or “turns over” its portfolio). A higher portfolio turnover will cause the Fund to incur additional transaction costs and may result in higher taxes when Shares are held in a taxable account. These

costs, which are not reflected in Total Annual Fund Operating Expenses or in the example, may affect the Fund’s performance. Because the Fund has not yet commenced operations, portfolio turnover information is unavailable at this time.
