Where a subsidiary of the listed issuer (whether or not consolidated in the accounts of the listed issuer, whether or not wholly-owned and whether held directly or indirectly) allots shares, it is necessary to calculate a value for the purpose of the consideration ratio. This is taken as the value of the shares issued to allottees (that are not part of the listed group) and is restricted to only those shares issued which are in excess of those necessary to maintain the allottees' relative percentage interest in the subsidiary.
