If TWW proceeds with the project as originally planned, there is a 40% chance that controversy about the financial "gratuity" will damage its reputation and lose $500 million in future business opportunities. If TWW spends $100 million to contract with an outside bank to oversee cash payments, the probability of this continuing controversy will decline to 20%.

Choice a: Do nothing and proceed with the project as originally planned.

Choice b: Proceed with the project and contract with an outside bank.

Choice c: Shut down the project.
