Delisting of InvIT units: prescribed grounds, required exit option, and post-delisting registration surrender govern the process. The investment manager must apply for delisting when prescribed public-holding or unit-holder thresholds are breached, when no projects or assets remain for a sustained period (with a possible unitholder-approved extension), on Board or stock-exchange direction for regulatory or listing violations, on trustee and investment manager request with unitholder approval, or on unitholder application. Exit options must be provided to dissenting unit holders. The Board or exchanges may approve, reject, or grant time to comply; delisted InvITs must surrender registration and cease InvIT activities while remaining liable for prior acts.
