Expense Example [Heading] Example
Expense Example Narrative [Text Block]
This example is intended to help investors compare the cost of investing in shares of the Fund with the cost of investing in other funds. The example assumes an investor invests $10,000 in shares of the Fund for the time periods indicated. The example also assumes that the investment has a 5% return each year and that the Fund’s operating expenses remain the same. The example does not reflect any brokerage commissions that an investor may pay on purchases and sales of Fund shares. Although actual costs may be higher or lower, based on these assumptions, whether an investor does or does not redeem the shares, an investor’s expenses would be:

Portfolio Turnover [Heading] Portfolio Turnover
Portfolio Turnover [Text Block]
The Fund may have 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 Fund shares are held in a taxable account. These costs, which are not reflected in the
annual fund operating expenses or in the example, affect the Fund’s performance. Because the Fund had not yet commenced operations prior to the date of this Prospectus, it does not have a portfolio turnover rate to provide.
