Concept:Called-up capital is the portion of a company's issued shares that shareholders have been required to pay for at a given time.

The company may request only part of the share value as an initial or installment payment.
This requested amount is known as the called-up capital.

It also differs from subscribed and issued capital, which refer to the shares actually taken up or allotted, regardless of how much has been paid.
Therefore, the part payments made on allotted shares represent the called-up capital.
