The new list will become effective from December 15 onwards. SEBI has also decided to examine how delivery of demat shares can be enhanced at stock exchanges by asking brokers to rectify bad delivery shares only by demat shares.

The decisions were taken by the working group on depositories which met on Wednesday. It was also decided to consider expanding the list of 10 securities where all investors have been asked to trade only demat shares from January 4 onwards and a meeting for this has been convened on October 20.

Of the 110 scrips identified for mandatory institutional demat trading, the diktat is effective in the case of 50 securities while the remaining 60 will be part of the directive from October 15 onwards. With the fresh addition almost all the top companies and more so most of those offering the demat facility would have been covered under mandatory demat trading for institutions provision of SEBI.

It was also decided to consult stock exchanges for making it mandatory on brokers to rectify bad delivery shares only in demat form and also make it mandatory for brokers who have a history of introducing bad delivery stock to deliver shares only in the demat form. To give a further boost to demat delivery, custodians will be asked to make prompt payment in respect of shares received by them fully in the demat form.

It was decided that delivery of demat shares will be treated as good delivery for negotiated deals also. Besides, institutional investors should compulsorily settle trades executed as negotiated deals in demat form with respect to securities where they have been mandated to trade only in demat shares.
