Siemens AG is considering a project that requires an initial investment of $700,000. The asset will be depreciated over five years at 20% per year. The cash flows are expected to be:

Year	Inflow ($)	Outflow ($)
Year 1	210,000	85,000
Year 2	220,000	90,000
Year 3	230,000	95,000
Year 4	240,000	100,000
Year 5	250,000	105,000

a. What is the payback period?
 b. Calculate the accounting rate of return (ARR) each year and the average.
 c. Assuming a cost of capital of 10%, what is the net present value (NPV) of the cash flows?
 d. Should Siemens AG accept the project?
