A cash flow statement provides insights into the changes in a business's cash position between two balance sheet dates, detailing cash inflows and outflows from operating, investing, and financing activities. It is crucial for assessing liquidity, aiding management in meeting obligations, and understanding financial dynamics despite limitations in assessing profitability and providing a comprehensive financial picture. The statement differs from a funds flow statement, which focuses on working capital, while the cash flow statement centers on cash and cash equivalents.
