Wealth-tax liability expansion: trustees and similar fiduciaries now liable for excess asset value over beneficiaries' interests under amendment. Where assets held for others exceed the aggregate value of beneficiaries' interests, wealth-tax is levied and recovered from the fiduciary (court of wards, administrator-general, official trustee, receiver, manager or other trustee) in respect of the excess, treating that excess as the net wealth of a resident individual and applying either Schedule I rates or a specified alternate rate, whichever is more beneficial to revenue; amendments also adjust provisos and add an Explanation deeming beneficiaries' shares indeterminate unless expressly stated and ascertainable in the creating order or instrument.
