The statement of cash flows shows the cash inflows and the cash outflows of the business. A company might have the most loyal customers and most co-operative suppliers but there is no chance that they will not need cash for its day to day operations. A cash flow statement shows the amount of money (cash) that the company managed to bring from the operating activities, the cash that it paid or received from investing activities (purchase or disposal of property, plant and equipment for example) and the cash paid or received from the financing activities (loans, dividends etc).
There is no doubt that a company that has high cash outflows and low cash inflows will face insolvency problems. The latter makes the statement of cash flows quite important.
