** The Fund operated as a series of The Motley Fool Funds Trust (the “Predecessor Fund”) prior to December 21, 2016 at which time the Predecessor Fund was reorganized into the Fund. The performance shown for periods prior to December 21, 2016 represents the performance of the Predecessor Fund. These returns reflect expense waivers by the Fund’s investment adviser. Without these waivers, returns would have been lower.
