The selection of Todd was a result of an impending restructuring of Todd-Veredus in which the firm is closing its Veredus division, a division unrelated to the Funds&amp;#8217; management. This reorganization would have resulted in the termination of the Funds&amp;#8217; current sub-advisory agreement. In selecting Todd as sub-advisor, the Board considered, among other factors, the recommendation of the Funds&amp;#8217; advisor, Touchstone Advisors, Inc. (the &amp;#8220;Advisor&amp;#8221;), and the Advisor&amp;#8217;s conclusion that the restructuring will not result in any interruption or change to the Funds&amp;#8217; investment strategies or personnel. The entire investment management team and staff who historically and currently manage the Funds will remain in place and continue to execute the same investment goals and strategies. Accordingly, all references to Todd-Veredus Asset Management LLC and Todd-Veredus as sub-advisor of the Funds in each Fund&amp;#8217;s Summary Prospectus, Prospectus, and Statement of Additional Information are deleted and replaced with Todd Asset Management LLC and Todd, respectively.&lt;/font&gt;&lt;/font&gt;&lt;/p&gt;
