For the purposes of this Schedule a group shall be treated as including any body corporate in which a member of the group holds a qualifying capital interest.

A qualifying capital interest means an interest in relevant shares of the body corporate which the member holds on a long-term basis for the purpose of securing a contribution to its own activities by the exercise of control or influence arising from that interest.

Relevant shares means shares comprised in the equity share capital of the body corporate of a class carrying rights to vote in all circumstances at general meetings of the body.

A holding of 20 per cent or more of the nominal value of the relevant shares of a body corporate shall be presumed to be a qualifying capital interest unless the contrary is shown.

In this paragraph “equity share capital” has the same meaning as in the Companies Act 1985 and the Companies (Northern Ireland) Order 1986.
