Pre filing draft offer document enables structured Board review, public comments and mandatory due diligence before an IPO. A new pre filing framework allows issuers to file a draft offer document with the Board via lead managers, requires simultaneous stock exchange filing and specific promoter identifiers, and obliges lead managers to submit due diligence certificates (new Forms AA, CA, DA). The Board may issue observations within defined triggers; issuers must file updated draft red herring prospectuses, host the updated draft for public comments, incorporate changes, and file the final offer document with supporting auditor and promoter contribution confirmations. Larger issues must engage a credit rating agency to monitor use of proceeds and provide quarterly reports until full utilisation.
