Mutual fund schemes must follow trustee-authorised winding up, pay liabilities, cover winding up costs, and distribute net proceeds proportionally. Trustees must obtain simple majority unitholder authorisation to wind up a scheme and then, as authorised or directed by the Board, dispose of scheme assets in the best interest of unitholders. Sale proceeds must first discharge due liabilities, then cover winding up expenses, and remaining amounts are paid to unitholders proportionally to their interests as of the winding up decision date. Custodian, audit and investor communication costs qualify as winding up costs; investment/advisory fees and distribution commission do not. Trustees must file a detailed winding up report with an auditor's certificate, and disclosures continue until the scheme ceases to exist.
