Ownership limits in depositories restrict shareholding and require divestment of excess holdings under prescribed transition rules. Regulation 20 caps shareholding and voting rights in a depository, requiring inclusion of any instrument that directly or indirectly confers present or future voting rights or entitlement to equity when calculating shareholding. A transitional rule permits existing excess equity or rights only for a limited period, obliging reduction to the prescribed limit within the transition period specified by the Board.
