| Performance Narrative [Text Block] | The following bar chart and performance table below provide some indication of the risks of an investment in the Fund by comparing the Fund’s average annual returns with those of a broad measure of market performance. The Fund’s past performance (before and after taxes) is not necessarily an indication of its future performance. Performance reflects contractual fee waivers in effect. If fee waivers were not in place, performance would be reduced. Current performance information is available at no cost by calling (800) 806-1112 (toll free) or (312) 557-3164. |
