Concept:The part of issued capital that the company has not yet asked shareholders to pay is known as uncalled-up capital.
Explanation:Issued capital is the total value of shares offered by a company to investors.
When shares are issued, the company may demand the full amount immediately or only a portion of it.
The amount already demanded from shareholders is called called-up capital.
The remaining amount, which the company can demand later, is the uncalled-up capital.
Hence, the proportion of issued capital that is to be paid in the future is the uncalled-up capital.
