QUESTION 4:
Honda Motor Co. decides to upgrade a new assembly line to increase productivity. This
upgrade requires an initial investment of $3,200,000 and will generate $850,000
revenue in year 1 of operation. The system will incur $250,000 in maintenance
expenses in the first year. The investment cost of all the equipment necessary for
upgrading is classified as a 5-year MACRS property for depreciation purposes. The
expected salvage value of all the equipment is $200,000 at the end of the project life.
The firm pays taxes at a rate of 25% and has a MARR of 18%. The assembly lines have
a 6-year life. Revenues for operation will increase at 5% each year and expenses will
increase at 3% each year. A loan is to be taken out for 28% of the initial investment
amount. The loan will be repaid over the project life in yearly payments, at an annual
interest rate of 15%.

Calculate the following:
a. Determine the allowed depreciation amounts [3 points]
b. Calculate the repayment schedule of the loan [3 points]
c. Calculate the Gains/Losses associated with Asset Disposal [1 points]
d. Create the Income Statement [5 points]
e. Develop a Cash Flow Statement [5 points]
