Code of conduct for bankers to an issue mandates investor protection, conflict disclosure and prohibition of insider trading. The amendment substitutes a new Code of Conduct for Bankers to an Issue, imposing duties to protect investors by observing integrity, due diligence, independent professional judgment and prompt, ethical performance. It prescribes grievance redressal mechanisms, timely submission of collection figures, specific prohibitions (no collusion, no late acceptance of applications, no parting with issue proceeds before listing), disclosure and resolution of conflicts of interest, prohibition of insider trading and market manipulation, and requirements for internal controls, fit-and-proper personnel, and compliance-officer authority.
