Question

When a company has issued stock with an assigned par value, why is it important to account for paid-in-capital in excess of the par amount separately?

Answer 1

It is always important to consider the amount for paid-in-capital in excess of the par amount separately because such an amount received is considered to be premium on stock.
It is the value which should be presented in the financial statements as profits generated and increases the total cash flows.

Also, such paid-in-capital in excess of the par amount should be shown separately because regulations of financial statements requires so.

When a company has issued stock with an assigned par value, it means that the company have set up a assigned amount for the stock and if stock is sold for more than that assigned par value than it is considered as premium, if sold less than that assigned par value than considered as sold on discount.
The company will have a benefit while the sale of stock above par value and below par value while buyback of such stock.
