How can I find the net realizable value per unit. I have the units in hand: 1,350,600, 

cost per unit: 617, 

cost: 833,320,200 

willing to pay: 165, 

Cost to sell: 165*1,350,600= 222,849,000.

Realizable value per unit?

Write down per unit?

Number of Units?

Total write down? 

 I need the realizable value per unit. After that, I need to find the write-down per unit and the number of units to find the total write-down.
