Merchant banker obligations ensure procedural, disclosure and fund compliance in buy-back processes and reporting requirements. Regulation 20 assigns to the merchant banker primary responsibility for ensuring the company can implement the buy-back, that escrow and firm monetary arrangements are in place, the public announcement and letter of offer are prepared and filed, and a due diligence certificate accompanies the draft letter of offer. The merchant banker must confirm disclosures are true and adequately sourced, ensure compliance with section 77A and section 77B of the Companies Act and other applicable laws, instruct release of residual escrow funds after obligations are met, and file a final report to the Board within fifteen days of buy-back closure.
