Example

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 Fund 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 the same. Although your actual costs may be higher or lower, based on these assumptions (and giving effect to fee waivers and expense reimbursements) your costs, whether you sell or hold your Fund Shares, would be:

Expense Example, With Redemption [Table]

	Year 1		Year 3
	$76		$237

Expense Example, No Redemption [Table]

	Year 1		Year 3
	$76		$237

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