Voluntary delisting of non convertible debt securities governed with specified applicability, exclusions, and insolvency disclosure duty. The Chapter governs voluntary delisting of non-convertible debt securities and non-convertible redeemable preference shares but excludes cases where instruments were issued by public issue, have over two hundred holders in an ISIN excluding QIBs, have been delisted due to penalty or specified rule grounds, have been delisted upon redemption, or are delisted pursuant to an insolvency resolution plan. Delisting pursuant to an insolvency resolution plan must be disclosed to the relevant stock exchanges within one working day, and a separate delisting regulation does not apply to voluntary delisting under this Chapter.
