Disclosure requirements: offer documents must provide material investor disclosures and lead managers must verify accuracy through due diligence. Regulation 28 mandates that offer documents for debt securities and non-convertible redeemable preference shares contain all material, true, fair and adequate disclosures necessary for informed investor decisions, including Schedule I disclosures and Companies Act requirements. Lead managers must exercise due diligence, verify disclosure veracity, and confirm regulatory compliance. Audited financial statements must be no older than six months, with specified exceptions allowing unaudited stub-period financials with limited review for listed issuers or certain subsidiaries. Lead managers must also disclose a three-year track record of public issues on their websites.
