In the Companies Acts -
"called-up share capital", in relation to a company, means so much of its share capital as equals the aggregate amount of the calls made on its shares (whether or not those calls have been paid), together with -
(a) any share capital paid up without being called, and
(b) any share capital to be paid on a specified future date under the articles, the terms of allotment of the relevant shares or any other arrangements for payment of those shares; and
"uncalled share capital" is to be construed accordingly.
