The document summarizes the key proposed changes to SEBI's takeover regulations and perspectives from industry. Some major changes include increasing the threshold for a mandatory open offer from 15% to 25%, requiring any change in control to be through an open offer, increasing the minimum offer size from 20% to 100%, and reducing the timeline for completing an open offer. While some changes like a higher threshold align with global norms, industry has concerns around issues like cost increases and fewer open offer opportunities due to the changes.
