Financial statements are used by investors and businesses to analyze the financial performance and situation of an entity. There are four key financial statements: the statement of profit or loss, which shows revenues, costs and expenses to determine profit or loss over a period; the statement of financial position (balance sheet), which measures assets, liabilities and equity to analyze the entity's financial situation; the statement of changes in equity, which details changes in owners' equity; and the statement of cash flow, which shows how balance sheet accounts and income affect cash flow from operating, investing and financing activities.
