The document discusses the post-issue activities of a merchant banker. There are two main post-issue activities: post-issue monitoring reports and redressal of investor grievances. As part of post-issue monitoring, the merchant banker must ensure submission of monitoring reports and a due diligence certificate to the regulatory body. They must also actively work to resolve any investor complaints regarding allotment or refunds. The merchant banker is responsible for coordinating with other intermediaries and ensuring issues are fully subscribed before closing. They must provide information on underwriters who do not meet commitments and ensure funds are kept separately as required.
