Replacement Analysis

St. Johns River Shipyards' welding machine is 15 years old, fully depreciated, and has no salvage value. However, even though it is old, it is still functional as originally designed and can be used for quite a while longer. A new welder will cost $181,000 and have an estimated life of 8 years with no salvage value. The new welder will be much more efficient, however, and this enhanced efficiency will increase earnings before depreciation from $29,000 to $71,500 per year. The new machine will be depreciated over its 5-year MACRS recovery period, so the applicable depreciation rates are 20.00%, 32.00%, 19.20%, 11.52%, 11.52%, and 5.76%. The applicable corporate tax rate is 25%, and the project cost of capital is 11%. What is the NPV if the firm replaces the old welder with the new one? Do not round intermediate calculations. Round your answer to the nearest dollar. Negative value, if any, should be indicated by a minus sign.
