1. Banking. The capital stock of a bank, Federal Reserve Bank, or international development bank subscribed to, and paid by, its stockholders. Paid-in capital is the amount contributed by stockholders to obtain a bank charter and commence business. Federal Reserve Member Banks are required to purchase shares in their district Federal Reserve Bank equal to 6% of their capital and surplus; only 50% of this amount actually is paid. The remainder, or callable capital, can be called at any time.
2. Finance. The difference between par value of a corporation's outstanding shares of stock and current market value. This value is adjusted downward when a corporation repurchases its own stock. Contributions in excess of par value or donations not counted toward capital stock are called capital surplus.
