Capital surplus

Capital surplus is a term that frequently appears as a balance sheet item as a component of shareholders' equity. Capital surplus is used to account for that amount which a firm raises in excess of the par value (nominal value) of the shares (common stock).

This is called as Additional paid in capital in US GAAP terminology but, additional paid in capital is not limited to share premium. It is a very broad concept and includes tax related and conversion related adjustments.

Taken together, common stock (and sometimes preferred stock) issued and paid plus capital surplus represent the total amount actually paid by investors for shares when issued (assuming no subsequent adjustments or changes).

Shares for which there is no par value will generally not have any form of capital surplus on the balance sheet; all funds from issuing shares will be credited to common stock issued.

Some other scenarios for triggering Capital Surplus include when the Government donates a piece of land to the company.
