Saint John River Shipyards welding machine is 15 years old, is 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 $182,500 and have an estimate life of 8 years with no salvage value. The new welder will be much more efficient, however, and this enhanced efficiency will increase annual cash flows before taxes (not including any CCA tax shield effects) from $27,000 to $74,000 per year. The new welder falls into Class 43 with a CCA rate of 30%. The applicable corporate tax rate is 25%, and the project cost of capital is 12%. What is the NPV if the firm replaces the old welder with the new one?
