s 547 Called-up share capital
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— any share capital paid up without being called, and 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.
