ABC Ltd.must decide whether to replace an existing machine. The company do not currently pay taxes. The replacement machine costs $9000 now and requires maintenance of $1000 at the end of every year for eight years. At the end of 8 years the machine would be sold for $2000 (after any taxes). The existing machine requires increasing amounts of maintenance at the end of each year and its salvage value falls each year as shown:

Year Maintenance Cost ($) After-tax Salvage Value

0,,,,,,, 0,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, 4000

1 ,,,,,,, 1000 ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,2500

2,,,,,,,, 2000,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,1500

3 ,,,,,,,,3000,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, 1000

4 ,,,,,,,,4000,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, 0
