Internal funds are obtained from the retention of earnings. If firms require external financing, the financial managers can structure equity or debt to finance a firm’s operations. Equity represents ownership interests and can be either common or preferred stock. Debt is money borrowed from creditors.

Intermediaries serve the role of servicing savers and borrowers to achieve their desired pattern of inter-temporal consumption. Instead of savers and borrowers having to deal with each other on an individual basis, they deal with the intermediary. The intermediary realizes a profit by lending at a higher rate than it pays savers (the spread).
