As previously reported in Equinox Frontier Funds’ (the “Trust”) Form 8-K, which was filed with the Securities and Exchange Commission (“SEC”) on January 15, 2016, Equinox Fund Management, LLC, the managing owner of the Trust (the “Managing Owner”), had executed an offer of settlement with the SEC, which was subsequently accepted, to settle allegations made by each of the SEC and the Commodity Futures Trading Commission (“CFTC”) related to certain disclosures concerning the valuation of certain options invested in by certain of the series of the Trust (each, a “Series” and collectively, the “Series”), as well as the Managing Owner’s calculation and disclosure of management fees paid by investors in certain of the Series.

On January 12, 2016, the Managing Owner executed an offer of settlement that was submitted to the CFTC in relation to the above-mentioned allegations. The CFTC accepted the offer of settlement on or about March 14, 2016 pursuant to which the Managing Owner neither admits nor denies the negligence-based allegations made by the CFTC, as described in further detail in the Form 8-K filed on January 15, 2016, and has agreed to pay a civil monetary penalty of $250,000 to the CTFC.
