3. Carsem Sdn Bhd acquired a high speed electronic assembly machine two years ago for RM 50,000. The assembly machine is now valued at RM 25.000 and can be replaced by an upgraded model with a purchase price of RM 42,500. Alternatively, the assembly machine can be kept for maximum of another year before it becomes obsolete. The proposed new model has a useful life of not more than two (2) years. The projected resale values (MV Market Value) and maintenance & operating costs (O&M Costs) for both options are shown in Table Q3 (on year-by-year basis).
