Fee schedule for buy-back filings: merchant bankers must pay tiered regulatory fees based on offer size upon submission. Amendment to Schedule IV of the SEBI (Buy-Back of Securities) Regulations replaces paragraph (1) to require every merchant banker, while submitting the offer document or a copy of the public announcement to the Board, to pay fees pursuant to a tiered schedule based on the offer size. The amendment is titled as the 2006 Amendment Regulations and comes into force on publication in the Official Gazette, thereby modifying the principal 1998 Buy-Back Regulations.
