Example

| Expense Example Narrative [Text Block] |
The Example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the
Fund for the time periods indicated whether or not you redeem all of your shares at the end of those
periods (except as indicated with respect to Class C shares). The Example reflects Class C shares converting
into Investor Class shares in years 9-10; expenses could be lower if you are eligible to convert to Class
A shares instead. The Example also assumes that your investment has a 5% return each year and that the
Fund's operating expenses remain the same. The Example reflects the contractual fee waiver and/or expense
reimbursement arrangement, if applicable, for the current duration of the arrangement only. Although
your actual costs may be higher or lower, based on these assumptions your costs would be:

| 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 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 31% of the average value of its portfolio.
