Filing fees for draft offer documents set tiered payment rates and advance electronic payment rules for different issue types. Fees for draft offer documents, letters of offer and updation must be paid in advance by electronic or online transfer. The Schedule sets tiered fee rates for public issues, rights issues and listings without public issue, with percentage-based fees for larger sizes and prescribed reduced rates for filings within one year after an observation letter. Updation fees are charged per section subject to a cap related to the original filing fee or a fixed minimum. Estimated fees may be paid where issue size is indeterminate, with adjustments made after finalisation of allotment.
