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

The Fund may pay 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 is new, no portfolio turnover information has been provided.
