| Expense Example Narrative [Text Block] | This Example is intended to help you compare the cost of investing in shares of the Portfolio with the costs of investing in other mutual funds. The Example assumes that you invest $10,000 in shares of the Portfolio for the time periods indicated, and then hold or redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and the Portfolio’s operating expenses remain the same. Although your actual costs may be higher or lower, the Example shows what your costs would be based on these assumptions. |
| Portfolio Turnover [Heading] | <span style="color:#00687D;font-family:Arial Narrow;font-size:12pt;font-weight:bold;">Portfolio Turnover</span> |
| Portfolio Turnover [Text Block] | The Portfolio pays transaction costs 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 Portfolio shares are held in a taxable account. These costs, which are not reflected in the Annual Portfolio Operating Expenses or in the Example table, can adversely affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s portfolio turnover rate was 584% of the average value of its portfolio. |
