SEBI has approved measures to strengthen the securities market and corporate governance of listed entities. These changes include allowing self-sponsored REITs and InvITs with board control or investment manager control. Unitholders with a 10% or higher holding in REITs or InvITs will have the right to nominate representatives on the boards. SEBI has also reduced the timeline for listing shares in public issues from T+6 days to T+3 days to expedite the listing process. Additionally, foreign portfolio investors will have to meet additional disclosure requirements to prevent violations of minimum public shareholding norms.
