1. Timco airlines is a large airplane maker. It recently built the T123. It can carry 500 passengers on two levels. Initial project investments were $13B. Assume that the initial investment was paid on Dec 31, 2010. Assume that Timco will produce 60 aircraft per year for five years. Each aircraft will be sold for $230M and total operating costs are 75% of revenues. Assume that revenues and costs occur at year-end with the first revenues (and costs) occurring on Dec 31, 2011. What is the NPV of the project if Timco's cost of capital is 11%? Calculate the NPV as of Dec 31, 2010. Ignore taxes and assume that there are no terminal year cash flows. Show your work, as appropriate and clearly state your answer (5 points)
