Expense Example Narrative [Text Block]

This Example is intended to help you compare the cost of investing in the Institutional Class and Investor Class of the Fund with the cost of investing in other mutual funds. The Example assumes you invest $10,000 in the Institutional Class and Investor Class for the time periods indicated and then 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 that the Fund's operating expenses remain the same. The one-year figure is based on total annual Fund operating expenses after expense reimbursement. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

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 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. During the most recent fiscal year, the Fund's portfolio turnover rate was 10% of the average value of its portfolio. The Fund's portfolio turnover rate may vary from year to year as well as within a year.
