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. The 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 reflects the Manager’s expense waivers and reimbursements for the contractual period and the total operating expenses without waivers for the periods thereafter.

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 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. As of the date of this Prospectus, the Fund has not yet commenced operations and portfolio turnover data therefore is not available.
