A stakeholder is a party that has an interest in a company and can either affect or be affected by the business. The primary stakeholders in a typical corporation are its investors, employees, customers, and suppliers.

An effective annual interest rate is the real return on a savings account or any interest-paying investment when the effects of compounding over time are taken into account. It also reflects the real percentage rate owed in interest on a loan, a credit card, or any other debt.

Book value is equal to the cost of carrying an asset on a company's balance sheet, and firms calculate it netting the asset against its accumulated depreciation. As a result, book value can also be thought of as the net asset value (NAV) of a company, calculated as its total assets minus intangible assets (patents, goodwill) and liabilities. For the initial outlay of an investment, book value may be net or gross of expenses such as trading costs, sales taxes, service charges, and so on.
