Atlantic Control Company purchased a machine 2 years ago at a cost of $70,000. 

The machine is depreciated using a simplified straight line over its class useful life of 7 years. 

The machine would have no salvage value at the end of year 7, but could now be sold for $40,000. 

A new replacement machine can be purchased for $80,000. 

The new machine would depreciate in 5 years. 

Rapidly changing technology has made this project necessary. 

Delivery and installation charges will be $10,000 and a net working capital investment of $5,000 will be required for installation. 

The new machine will not increase sales, but it will reduce operating costs by $20,000 per year. 

The company's marginal tax rate is 35%.

What is the annual differential cash flow for years 1 through 5?
