Dematerialisation requirement: transfers, issuances and transmissions must be effected only in dematerialised form, tightening compliance. Regulation 17 requires prior shareholder approval for appointment or re appointment of any person earlier rejected by shareholders, with the notice including detailed justification by the Nomination and Remuneration Committee and the Board. Operational amendments shift reconciliation to a quarterly basis, require issuance and transfers to be effected in dematerialised form within prescribed periods, prohibit processing transfer requests unless securities are dematerialised, and mandate that transmission or transposition be effected only in dematerialised form; Schedule VI provisions permitting re materialisation and physical certificate delivery are removed.
