Disclosure obligations for promoters require prompt initial and threshold triggered reporting to company and stock exchange. Amendments to Regulation 13 impose initial disclosure duties on any person who becomes a promoter or part of a promoter group to disclose shareholding to the company in Form B within two working days, and require disclosure to the company and the stock exchange in Form D of total holdings and changes where such change exceeds prescribed thresholds; Schedule III is revised to substitute standardized Form B and Form D templates capturing identification, holdings, transaction details, trading member and exchange information.
