Question: Suppose a friend of yours showed you the pro forma income statements for his startup and exclaimed excitedly that during the first three years of operations his firm will make a net income of $150,000 per year, which is just the amount of money ($450,000) the firm will need to pay off a three-year loan. Given your study of this chapter, why is it that your friend may not actually have $450,000 in cash, even though his pro forma income statements say that he will earn that amount of money?
