A Cash Flow Statement is a financial report that details the cash inflows and outflows of a company over a specific period. It is divided into three sections: operating activities, investing activities, and financing activities. This statement helps assess the company’s liquidity, solvency, and overall financial health. By tracking cash movements, it provides insights into the company's ability to generate cash to fund operations, pay debts, and invest in growth. Businesses and investors use it to evaluate the sustainability of a company's cash flow and its financial stability.
