Interse allocation of responsibilities requires lead merchant bankers to delineate activity-wise duties and notify the issuer's board. Lead Merchant Bankers must allocate activities inter se, notify the issuer's board of the Lead Merchant Banker responsible for each activity with signatures of all Lead Merchant Bankers, and where joint and several responsibility exists, a designated coordinator must provide information to the board. Designated Lead Merchant Bankers must ensure compliance with disclosure and investor protection guidelines, oversee selection and performance of agencies, manage marketing and regulatory formalities, and ensure completion of post-issue tasks including allotment, listing, certificate despatch and refunds.
