This information is intended to give you some indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and how the Fund’s average annual returns over time compare with those of a broad measure of market performance and an additional index with characteristics relevant to the Fund's investments. The Fund’s past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. The Class R Shares of the Fund would have different returns from the Institutional Shares because, although the shares are invested in the same portfolio of securities, Class R Shares have different expenses. |
