 If trustees wished to invest in " wide range " investments , they were required to have the trust fund valued and divided into two parts – three quarters of the value in one part , and a quarter in the other . The quarter was to be invested in " wide range " investments , while the remainder was restricted to " narrow range " investments . The valuation had to be done by " a person reasonably believed by the trustee to be qualified to make it " . This division of funds was permanent , and the quarter and three quarters became distinct units . The permanence of the division was the Act 's most controversial section .
