Offer document requirements: electronic files must match hard copy and merchant bankers must certify compliance or documents won't be processed. Draft and final offer documents must be submitted as soft copies in both HTML and PDF on a single floppy per issue, each containing one file; merchant bankers are responsible for ensuring conversion integrity and must submit an undertaking certifying the HTML floppy exactly matches the hard copy. Floppies require a sticker identifying the merchant banker, issuer, issue type and due diligence signatory, with additional filing and issue opening date details; non compliance will result in the offer document not being processed, and a written confirmation to SEBI is required after website posting.
