As per Accounting Standard-3 various activities of cash flow statement are classified into three categories as follows
(i) Cash Flow from Operating Activities :These are the principal revenue producing activities of the enterprise and other activities. The cash flow statement begins with the operating activities section. Operating activities generally reflect cash generated and/or paid as a result of the firm’s core business functions. Under US GAAP, this category incorporates the cash received from customers, paid to suppliers, paid for operating costs, paid for income taxes, received from interest or dividends, and paid for periodic interest costs.
(ii) Investing Activities: These are the acquisition and disposal of long-term assets, other investments not included in cash equivalents. Cash flows from investing activities are those involving non-current capital assets used in the firm’s operations, such as Property, Plant, Equipment (PP&E) and intangible assets. When a company invests in new long-term capacity by acquiring either PP&E or another company, the investment is a cash outflow from investing activities. Disposals of these types of assets for cash generate inflows.
(iii) Financing Activities :These are the activities that result in changes in the size and composition of the owner’s capital and borrowings of the enterprise. Cash flows from financing activities are those that take place between a firm and its investors. These include both the equity investments of stockholders (owners) and the loans from bondholders and other creditors. When the company issues new shares, it records a cash inflow from financing, and when it repurchases shares, pays dividends or pays off debt, it records a cash outflow.
