Change in mutual fund scheme attributes requires notice and unitholder exit at prevailing NAV without exit load. Trustees must ensure that no change in the fundamental attributes of a scheme or fees affecting unitholders is carried out unless each unitholder receives written communication, an advertisement appears in a national and regional newspaper, and unitholders are offered an option to exit at the prevailing Net Asset Value without exit load. Changes in controlling interest of the asset management company similarly require prior trustee and Board approval, written notice and advertisement, and an exit option at prevailing Net Asset Value without exit load. The Seventh Schedule permits investment in mortgage-backed securitised debt rated at or above investment grade by a registered credit rating agency and sets caps on unlisted equity exposure for schemes.
