BBC Company owns a machine which was purchased 4 years ago for $ 75 000. Although the machine will last another 6 years, it will need a major overhaul (修理) costing $15 000 in another 2 yeaars. The net cash inflow from the machine are expected to be $45 000 annually. At present, the salvage value is $20 000 but this will drop to $10 000 in 6 years' time providing the overhaul is done.
You were at te local manufacturing(製造業) exhibition(展覽) where you were shown a new machine would result in net cash inflows of $55 000 annually, would last 6 years and would have a residual value of $8 000.
