The Cash Flow Statement provides information that Income Statement and Balance Sheet do not, as it is prepared on an accrual basis. It summarizes cash inflows and outflows for a period, analyzing the reasons for changes in cash balance between two balance sheet dates. The statement can be prepared using direct or indirect methods and is classified into three activities: operating, investing, and financing. The cash flow statement helps test liquidity, determines short-term viability, and is a valuable resource to understand the company's financial position.
