Subscribed stock is an equity instrument that has been purchased under the terms of a periodic payment plan. This approach is most commonly used for employee stock purchase plans, where a deduction is taken from an employee's paycheck and placed in a stock purchase fund. Once the cumulative amount of this deduction is sufficiently large, it is used to buy shares issued by the employer.
Subscribed stock has several advantages for the investor. There is no stockbroker commission, and the issuer may offer the shares at a small discount from the market price. This approach also works well for the issuer, since it has a ready source of funds.
