The bar chart and accompanying table shown below provide an indication of the risks of investing in the Fund. The bar chart shows the performance of the Fund’s Class A shares for each of the last ten full calendar years. Although Class C, N and I shares have similar annual returns to Class A shares because the classes are invested in the same portfolio of securities, the returns for Class C, N, and I shares are different from Class A shares because Class C, N and I shares have different expenses than Class A shares. The performance table shows how the average annual returns of Class A, C, I and N shares compare over time with those of a broad-based market index and a supplemental index (strategy benchmark) that the Adviser believes is more representative of the Fund’s investment universe. How the Fund has performed in the past (before and after taxes) is not necessarily an indication of how it will perform in the future.

The bar chart and performance table below show the variability of the Fund’s returns, which is some indication of the risks of investing in the Fund. The bar chart shows performance of the Fund’s Class A shares for the past ten years and includes the performance of the Fund’s Predecessor Fund (as defined below). Although Class C, Class N and Class I shares have similar annual returns to Class A shares because the classes are invested in the same portfolio of securities, the returns for Class C, Class N and Class I shares are different than Class A shares because Class C, Class N and Class I shares have different expenses than Class A shares. The performance table compares the performance of the Fund’s Class A, Class C, Class N and Class I shares over time to the performance of a broad-based market index and a supplemental index (strategy benchmark) that the Adviser believes is more representative of the Fund’s investment universe. You should be aware that the Fund’s past performance (before and after taxes) may not be an indication of how the Fund will perform in the future.

The Fund acquired all of the assets and liabilities of Epiphany FFV Strategic Income Fund, a series of Epiphany Funds (the “Predecessor Fund”), in a tax-free reorganization on December 14, 2018. In connection with this acquisition, shares of the Predecessor Fund’s Class A Shares and Class I Shares were exchanged for Class A Shares and Class I Shares of the Fund, respectively. Prior to May 31, 2017, the Predecessor Fund’s Class I shares were called Class C shares, and the fee structure was different. The Predecessor Fund had an investment objective and strategies that were, in all material respects, the same as those of the Fund, and was managed in a manner that, in all material respects, complied with the investment guidelines and restrictions of the Fund. The performance information set forth below prior to December 14, 2018, reflects the historical performance of the Predecessor Fund. Updated performance information is available at no cost by calling 1-877-771-3836 and on the Fund’s website at www.eventidefunds.com.
