Cash flow is the net amount of cash and cash-equivalents moving into and out of a business. Positive cash flow indicates that a company’s liquid assets are increasing, enabling it to settle debts, reinvest in its business, return money to shareholders, pay expenses and provide a buffer against future financial challenges. Negative cash flow indicates that a company’s liquid assets are decreasing. Net cash flow is distinguished from net income, which includes accounts receivable and other items for which payment has not actually been received. Cash flow is used to assess the quality of a company’s income, that is, how liquid it is, which can indicate whether the company is positioned to remain solvent.
