## Depreciation and Taxes Review

1. You bought a machine three years ago for \$5000. It has been depreciated with the straight line method assuming a tax life of 5 years and zero tax salvage. What is the book value of the machine at this time?

2. A machine costs \$5000, will result in a net income of \$1500 per year for five years. Its tax life and actual life are both five years. Its tax salvage and actual salvage are both zero. With a tax rate of 40%, what after tax cash flow should we consider to evaluate this investment? With an after-tax MARR of 10%, do we accept or reject the investment in the machine.

3. How would the situation change in 2 if the actual salvage of the machine were \$5000 while the tax salvage remained at zero? The capital gains tax is 40%. With an after-tax MARR of 10%, do we accept or reject the investment in the machine.

4. How would the ATCF of problem 2 change if the SYD method were used for depreciation? The tax salvage is 0 in this case and the tax life is 5 years. With an after-tax MARR of 10%, do we accept or reject the investment in the machine.

5. We assume that the ordinary income tax rate is the same as the capital gain tax rate. What kind of depreciation results in smallest total taxes over the life of the investment, SYD or straight line depreciation? Why?

6. Why would any investor prefer SOYD depreciation to the straight line depreciation?

7. A truck whose value on the books was \$3000 in 1995, was sold for \$4000 in the same year. \$200 was spent on minor repairs to ready the truck for sale. Was there a capital gain associated with the sale? If so, how much was it?

8. Under what circumstances would you pay a tax on money received as salvage for a piece of equipment?

9. How does depreciation affect the after-tax cash flow?
