Business Description
BCM provides investment advisory services to private funds, which may include funds sponsored by BCM, and separately managed accounts, collectively referred to as "Advisory Clients." BCM may offer investors in these funds or other clients the opportunity to participate in investments alongside the Funds, potentially through special purpose vehicles (SPVs). A potential conflict of interest exists in the allocation of expenses between BCM and its Advisory Clients, or among the Advisory Clients, which BCM addresses through an expense allocation policy.
BCM actively manages Advisory Client portfolios, reviewing them periodically to ensure conformity with investment objectives and guidelines. This review includes evaluating existing and potential investments, investment guidelines, suitability, cash availability, and investment objectives, considering factors like investment performance, changes in fundamentals, risk management, and market changes. BCM's success is heavily reliant on Aaron Davis, and the loss of his services could negatively impact Advisory Clients.
Investment Strategy
BCM's investment strategies may evolve over time due to market developments, new investment products, changing industry practices, and technological innovation. The investments made by BCM on behalf of Advisory Clients will be consistent with the Advisory Client’s investment objectives and guidelines.
BCM may use any trading or investment strategy, whether or not contemplated by the expected investment strategies described, that they consider appropriate or in the best interests of Advisory Clients, subject to applicable investment objectives and guidelines. There is no guarantee that any strategies applied will be successful. BCM intends to provide investment advisory services to private funds and separately managed accounts, collectively referred to as the “Advisory Clients.”
