Performance Narrative [Text Block]

The following information provides some indication of the risks of investing in the Fund by showing how the Fund’s performance has varied over time. Class A shares of the Fund commenced operations on June 12, 2018. The performance shown in the table below for periods prior to June 12, 2018 for Class A shares reflects the performance of the Fund’s Investor Class shares, calculated using the fees and expenses of Class A shares. If Class A shares of the Fund had been available during periods prior to June 12, 2018, the performance shown may have been different.

 

The bar chart depicts the change in performance from year to year during the periods indicated. The bar chart figures do not include any applicable sales charges that an investor may pay when they buy or sell shares of the Fund. If sales charges were included, the returns would be lower. The table compares the Fund’s average annual returns for the periods indicated to a broad-based securities market index and additional indices. The indices are not actively managed and are not available for direct investment. The bar charts and performance tables assume reinvestment of dividends and distributions. The Fund’s past performance (before and after taxes) does not necessarily indicate how it will perform in the future.
