Parkwalk funds invest in smaller and unquoted companies which carry a higher risk than many other forms of investment. There is no guarantee that target returns will be achieved. There is no liquid market for shares in unquoted companies and there can be difficulties, in valuing and disposing of investments in such companies. Tax reliefs will depend on the investors’ individual circumstance and are subject to change.
