Answer:
A firm that has $100 million in revenues does not mean that the firm has generated a cash flow of $100 million.
Explanation:
The revenue could be on account, in which case, the firm has literally not generated any cash flow, but decreased the cash flow instead. To increase the cash flow by $100 million as a result of revenue, this particular firm needs to collect the amount from its customers in cash. Cash flow is generated when cash is received and not when services or goods are sold.
