As per Clause 31, the company is required to send 6 copy (physical) of Annual report. This is in addition to the requirement that a soft copy of Annual report is also required to send to stock exchanges so that it can be uploaded at BSE/NSE website.
But in view of the ministry green initiatives, it looks like that even sending soft copy of AR will be sufficient.
Recently on 05th oct. SEBI has ameded the Listing Agreement to facilitate the company to send soft copy of AR to the shareholders whose email is available with Company in line of MCA green initiatives.
Therefore in my view, soft copy will be sufficient.
