a cash flow statement shows exactly how much money a company has received and how much it has spent, traditionally over a period of one month. it captures the current operating results and changes on the balance sheet, such as increases or decreases in accounts receivable or accounts payable, and does not include noncash accounting items such as depreciation and amortization. the cash flow generally comes from revenue received as a result of business activity, but it may be augmented by funds available as a result of credit. a cash flow statement is used to determine the short-term viability and liquidity of a company, specifically how well it is positioned to pay its bills and vendors.
