The statement of cash flows identifies cash inflows and outflows for a period, usually one year. It is based on cash accounting. Cash includes cash on hand and demand deposits, less overdrafts due within 24 hours. Cash equivalents are short-term, highly liquid investments convertible to cash within 3 months. The statement categorizes cash flows as operating, investing, or financing activities. The indirect method is used to disclose cash flows to external parties, starting with operating profit and adjusting for non-cash items and changes in working capital. Revaluations and bonus share issues are not shown as they do not impact cash.
