(ii)as a result of the transaction ceases to be a member of the same group as the purchaser.
(3)For the purpose of sub-paragraph (2) a company is “above” the vendor in the group structure if the vendor, or another company that is above the vendor in the group structure, is a 75% subsidiary of the company.
