Issue advertisement format for public debt offerings requires specified issuer, issue, listing, credit rating and disclosure details. Schedule IV under regulation 8(1) prescribes a standard format for issue advertisements for public issues of debt securities, requiring issuer identification, issue particulars (including coupon and redemption summary), promoters, proposed listing venues, merchant bankers, compliance officer contact details, debenture trustees, and the credit rating with its meaning. The advertisement must state availability of application forms and the offer document (including risk factors) on specified websites, and include issue opening and closing dates and certification that it is issued by the issuer's directors.
