The new equipment will have a cost of $$2,400,000,$ and it will be depreciated on a straight$-$line basis over a period of six years $($years $16).$

$$ The old machine is also being depreciated on a straight$-$line basis. It has a book value of $$200,000($at year $0)$ and four more years of depreciation left $($$$50,000$ per year$).$

$$ The new equipment will have a salvage value of $$0$ at the end of the project's life $($year $6).$ The old machine has a current salvage value $($at year $0)$ of $$300,000.$

$$ Replacing the old machine will require an investment in net working capital $($NWC$)$ of $$50,000$ that will be recovered at the end of the project's life $($year $6).$

$$ The new machine is more efficient, so the firm$$s incremental earnings before interest and taxes $($EBIT$)$ will increase by a total of $$500,000$ in each of the next six years $($years $16).$ Hint: This value represents the difference between the revenues and operating costs $($including depreciation expense$)$ generated using the new equipment and that earned using the old equipment.

$$ The project's cost of capital is $13\%.$

$$ The company's annual tax rate is $35\%.$The net present value $($NPV$)$ of this replacement project is:

$-$$$354,177$

$-$$$425,012$

$-$$$407,304$

$-$$$301,050$
