Regulatory recognition of foreign exchanges may harm the combined companys ability to compete with less regulated entities.
Under current U.S. federal securities laws, foreign exchanges seeking to operate in the U.S. must meet substantially all of the regulatory requirements we face. The SEC has the authority to exempt foreign exchanges from these requirements and currently has granted one foreign exchange, Tradepoint LLC, an exemption based on low volume and other restrictions. Consequently, Virt-x Exchange Limited (the successor to Tradepoint LLC) is the only foreign exchange able to operate in the U.S. without meeting all the regulatory requirements we face. Recently, the SEC has begun discussing the possibility of reciprocal recognition of exchanges operating under comparable regulatory regimes. Based on the extent and manner in which the SEC pursues reciprocal recognition, there is a possibility that other foreign exchanges may enter the U.S. market without meeting all the regulatory requirements we meet. The entry of foreign exchanges into the U.S. market without complying with U.S. regulatory obligations would create additional competitive pressure on the combined company, particularly in the trading of dual-listed foreign securities.
