Legal and regulatory matters of this nature involve or may involve the Company’s activities as an employer, issuer of securities, investor, investment adviser, broker-dealer or taxpayer.

Tom Cummins v. Virtus Investment Partners Inc. et al On February 20, 2015, a putative class action complaint alleging violation of the federal securities laws was filed by an individual shareholder against the Company and certain of the Company’s current officers in the United States District Court for the Southern District of New York. The complaint was purportedly filed on behalf of all purchasers of the Company’s common stock between May 28, 2013 and December 22, 2014, inclusive (the “Class Period”). The complaint alleges that, during the Class Period, the defendants disseminated materially false and misleading statements and concealed material adverse facts relating to certain funds subadvised by F-Squared Investments. The complaint alleges claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended, and Rule 10b-5.
