Cash flow statement describes the flow of cash starting from the income in various operations of the company. It is a theoretical chart representing cash investment, expenditure and financing. People involved in cash flow statements in a company include accounting personnel, potential leaders, potential employees or contractors, investors and shareholders. They maintain cash records of each of their respective departments and help to keep track of all the cash flows in the company. A good and accurate cash flow statement is always required because this helps to keep track of how much tax needs to be paid.
