Under the first scenario, it can obtain a price of $12 share; under the second, it is able to obtain only $8 per share. In a best-effect deal, the bank obtains a fee of $2 million in both cases. In a firm commitment deal its profits depends on the price it is able to obtain. If it sells the shares for $12, it makes a profits of ($12-$10)*10 million=$20 million because it has agreed to pay corporation $10 per share. However, if it can only sell the shares for $8, it losses($10-$8)*10 million=$20 million because it still has to pay corporation $10 per share.
