The U.S. SEC stated that these funds may have 'incorrectly submitted registration statements' and that 'the disclosures in the registration statements regarding the identity of these funds as investment companies may be misleading.' REX Financial's General Counsel Greg Collett stated, 'We believe we can satisfy the SEC's concerns regarding investment companies, and we do not intend to launch the funds until we do so.'
