Additional Paid-In Capital

Additional Paid-In Capital - An additional paid-in capital would be additional capital that is paid into a corporation by investors over top of the par value of the capital stock. So, basically, it is the additional money the corporation received from investors over the value of the stock at the day's closing price. This is also called contributed capital, because the investors are contributing additional money to what is required, or paid-in capital, which in either case, is an additional investment in the company by investors.
