AMS Company has unexpectedly generated a one-time extra $5 million in cash flow this year. After announcing the extra cashflow, AMS's stock price was $55 per share (it has 1 million sharesoutstanding). The managers are considering spending $5 million on a project that would generate a single cash flow of $5.5 million in one year, which they would then use to repurchase shares. Assume the cost of capital for the project is 12%.

a. If they decide on the investment, what will happen to the price per share?
b. If they instead use the $5 million to repurchase stock immediately, what will be the price per share?
c. Which decision is better and why?
