9. Exercise 17.9 The state of Glottamora has $200 million remaining in its budget for the current year. One alternative is to give Glottamorans a one-time tax rebate. Alternatively, two proposals have been made for state expenditures of these funds. The first proposed project is to invest in a new power plant, costing $200 million and having an expected useful life of 20 years. Projected benefits of the new power plant are as follows: Years Benefits per Year ($ Millions) 1 - 5 0 6 - 20 40 The second alternative is to undertake a job retraining program, also costing $100 million and generating the following benefits: Years Benefits per Year ($ Millions) 1 - 5 40 6 - 10 28 11 - 20 8 The state Power Department argues that a 5 percent discount factor should be used in evaluating the projects because that is the government’s borrowing rate. The Human Resources Department suggests using a 12 percent rate because that more nearly equals society’s true opportunity rate. The present value interest factor at the end of years from 0 - 20 for the two discount rates are given in the following table. Discount Rates 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 5% 1.000 0.952 0.907 0.864 0.823 0.784 0.746 0.711 0.677 0.645 0.614 0.585 0.557 0.530 0.505 0.481 0.458 0.436 0.416 0.396 0.377 12% 1.000 0.893 0.797 0.712 0.636 0.567 0.507 0.452 0.404 0.361 0.322 0.287 0.257 0.229 0.205 0.183 0.163 0.146 0.130 0.116 0.104 Evaluate the projects using both the 5 percent and the 12 percent rates.
