Google is considering a project to move a fraction of its workforce out of Silicon Valley to a cheaper, more efficient location. There are two alternatives. Project 1: the initial move costs $45 million in year zero and generates costs savings of $32 million per year in each of the following three years (years 1,2, and 3). Project 2: the move costs $30 million in year zero and generates costs savings of $24 million per year in each of the following three years (years 1,2, and 3). Suppose Google's cost of capital is 15% per year. (a) What is the NPV of Project 1? (b) What is the IRR of Project 1? (c) Suppose Google can only choose to do one of the two projects a single time. Which project (if either) should it undertake? Explain why. (d) Suppose instead that Google can do either project multiple times until it spends $180 million in year zero. Which project(s) should it do now? Explain why.
