Consent for conversion: positive consent required; non-response not consent; option and redemption safeguards apply to holders. Conversion requires prior positive consent from holders; non-receipt of reply is not consent. If the convertible portion of listed instruments exceeds the prescribed threshold and conversion price was not fixed at issue, holders must be offered an option not to convert unless an upper price limit with justification was disclosed at issuance. Where holders decline conversion at the shareholders' meeting price, the issuer must redeem the non-converted portion within one month at not less than face value, except where such redemption is provided for in the offer document.
