Every Three Years a Major Component (Part #45)in a Machine

question 22

Essay

Every three years a major component (part #45)in a machine must be replaced. By doing this regular but expensive repair the machine can be used for 15 years. If Part #45 were not replaced, the machine could be used only for a maximum of six years. When the machine was originally purchased for $5,000,000 it was set up as one asset and depreciated over its estimated useful life of 15 years. Recently this repair was completed at a cost of $700,000 for Part #45. The earlier Part #45 cost $550,000 when it was installed three years ago. Neither the old nor the new Part #45 has any residual value.
