| 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. During the most recent fiscal year, the Fund’s portfolio turnover rate was 0% of the average value of its portfolio. This rate excludes the value of portfolio securities received or delivered as a result of in-kind creations or redemptions of the Fund’s shares and is calculated without regard to most derivatives. If such instruments were included, the Fund’s portfolio turnover rate would be higher. |
