Facebook is considering two proposals to overhaul its network infrastructure. The firm has received two bids. The first bid from Huawel will require a $24 million upfront investment and will generate $20 milion in savings for Facebook at the end of each year for the next 3 years. The second bid from Cisco requires a $93 million upfront investment and will generate $60 million in savings at the end of each year for the next 3 years. a. What is the internal rate of return [IRR] for Facebook associated with each bid? b. If the cost of capital (also appropriately called required return) for each investment is 17%, calculate the net present value (NPV) for Facebook of each bid. c. The larger-scale opportunity proposed by Cisco required an additional upfront investment of $69 million. However, it also is expected to generate extra end-of-year savings of $40 million for the next 3 years. In other words, an incremental upfront outlay of $69 million is expected to generate an incremental $40 million at the end of each year for the next 3 years. Calculate the IRR for this stream of incremental cash flows. Note: The approach here is exactly the same as you used for the two IRRs in part a
