Promoter shareholding dematerialization requirement: non-compliant securities to be traded only in trade-for-trade segment as reported to exchanges. Companies' securities will be admitted to trading in the normal segment only if the company has achieved 100% of promoter and promoter group shareholding in dematerialized form as reported to the stock exchanges; otherwise securities will trade in the trade-for-trade segment, with exchanges required to use the latest shareholding pattern filed under the listing agreement for assessment.
