With effect from April 5, 1999, the Company's shares are traded in Compulsory Demat form. Shareholders can no longer trade in the physical form.

Dematerialization of shares involves converting the physical shares into electronic form. Investors trade in the system through Depository Participants. The process leads to lower transaction costs and the elimination of bad deliveries and problems attached with the physical shares like theft, forgery and mutilation. Further, there are no charges as stamp duty during share transfer.

As on March 31, 2007, 94.86% of the paid-up capital had been dematerialised. (It was 94.59% & 94.08% of the paid up capital as on November 16, 2006 and March 31, 2006 respectively.)
