Compute the NPV of a project for which you have to invest $$16$ million today and you will receive $$20$ million in one year for sure $($assume the discount rate is zero: $0\%).$ In one year, you have to pay $$15$ million to reimburse a debt outstanding, and the rest of your portfolio could be worth $$100$ million or nothing with equal probability. What is the NPV of the new project from your point of view, i$.$e$.,$ taking into account the possibility that your portfolio next year cannot cover the debt reimbursement? The correct answer is $-3\mathrm{.}5$ million.
