Example

A fuel cell system costs $100,000 and is depreciated with straight line depreciation over 5 years, the salvage value after 5 years being $10,000. Find the present value of the tax deduction for depreciation if the incremental tax rate is T = 40%, and the discount rate rd is 15%.

GIVEN

C

= 100 k$

^salv

= 10 k$

N
