The Funds, through their investments in the Master Fund, pursue an active long-short equity strategy focused on the healthcare sector, generally on pharmaceutical and biotechnology companies that develop, discover, and commercialize drug therapies. The Funds, through the Master Fund, also invest opportunistically across the capital structure, including investments in credit instruments, private transactions, and alternative investments, which may include special purpose acquisition companies. The Clients’ assets may be invested in the securities of a limited number of issuers, emphasizing securities of companies in the healthcare industry and may at times emphasize particular sectors or sub-sectors of that industry.
