Portfolio Turnover [Text Block]
The Fund may pay transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio).

These costs, which are not reflected in 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 40% of the average value of its portfolio.
