Non-convertible redeemable preference shares definitions set issuance, listing and documentation requirements for issuers. Regulation 2 sets core definitions for issuance and listing of non-convertible redeemable preference shares, defining transactional and documentary terms-such as offer document, abridged prospectus, book building, private placement, public issue, issuer and designated stock exchange-and clarifies that such preference shares are redeemable under company law and not convertible into equity. It also provides for Board-specified meanings and adds a definition of wilful defaulter consistent with banking categorizations.
