The Riteway Ad Agency provides cars for its sales staff. In the past, the company has always purchased its cars from a dealer and then sold the cars after three years of use. The company's present fleet of cars is three years old and will be sold very shortly. To provide a replacement fleet, the company is considering two alternatives: Purchase alternative: The company can purchase the cars, as in the past, and sell the cars after three years of use. Ten cars will be needed, which can be purchased at a discounted price of $19,000 each. If this alternative is accepted, the following costs will be incurred on the fleet as a whole: At the end of three years, the fleet could be sold for one-half of the original purchase price. Lease alternative: The company can lease the cars under a three-year lease contract. The lease cost would be $71,000 per year (the first payment due at the end of Year 1). As part of this lease cost, the owner would provide all servicing and repairs, license the cars, and pay all the taxes. Riteway would be required to make a $15,500 security deposit at the beginning of the lease period, which would be refunded when the cars were returned to the owner at the end of the lease contract. Riteway Ad Agency's required rate of return is 15\%. Click here to view Exhibit 12B-1 and Exhibit 12B-2, to determine the appropriate discount factor(s) using tables. Required: 1. What is the net present value of the cash flows associated with the purchase alternative? 2. What is the net present value of the cash flows associated with the lease alternative? 3. Which alternative should the company accept? Information on four investment proposals is given below: Required: 1. Compute the profitability index for each investment proposal. (Round your answers to 2 decimal places.) 2. Rank the proposals in terms of preference. The management of Ballard MicroBrew is considering the purchase of an automated bottling mac machine would replace an old piece of equipment that costs $15,000 per year to operate. The new machine would cost $7,000 per year to operate. The old machine currently in use is fully depreciated and could be sold now for a salvage value of $25,000. The new machine would have a useful life of 10 years with no salvage value. Required: 1. What is the annual depreciation expense associated with the new bottling machine? 2. What is the annual incremental net operating income provided by the new botting machine? 3. What is the amount of the initial investment associated with this project that should be used for calculating the simple rate of return? 4. What is the simple rate of return on the new bottling machine? (Round your answer to 1 decimal place l.e. 0.123 should be considered as 12.3%.)
