first problem. am getting EBDAT for year 2016 as asked to 200 (profit margin 0,4) and total CFC to 80 (depreciation included) i know EBDAT is w/o, but as i can read from the problem i should ignore that?

Second:

i've come to the results
question:

4A: 2200 as first year ending cash, taking -2000 and adding 3000 depreciation aswell as 1200 as change in net operating working capital ( do i need to incluse surplus cash)

4B: to 5200 as ending cash. 0 net income and therefor only depreciation 2500 and change in NOPC 500

4C: as minus 40000 as its the initial assets value shot into the firm

4D: - 2800 using pseudo dividend?, Net income - 2000, depreciation 3000, change in NWC 3800.

4E: same method as above

4F: Getting my final NPV of 1.518.989, with the given factors of the text

would be pleased if someone could share some light if im complety off set or actually going in the right direction
