Operating revenue is generated from the core business activities of a company.
Primary expenses are incurred during the process of earning revenue from the primary activity of the business.
Unlike the balance sheet, the income statement covers a range of time, which is a year for annual financial statements and a quarter for quarterly financial statements.
Expenses include the cost of goods sold (COGS), selling, general and administrative expenses (SG&A), depreciation or amortization, and research and development (R&D).
Typical expenses include employee wages, sales commissions, and utilities such as electricity and transportation.
Cash from financing activities include the sources of cash from investors or banks, as well as the uses of cash paid to shareholders.
Financing activities include debt issuance, equity issuance, stock repurchases, loans, dividends paid, and repayments of debt.
