Cost evaluation of 5yr form2 and 2yr form3b

Hi Everyone!
The company I work for has gone through a division and we had to divide our assets. We have one Form2(2017) and one Form 3b(2021). They took the Form 3b and we have the form2. We are evaluating the devices to understand the cost that the other party needs to cover. We have already divided the materials and trays equally. This is only for the devices.

Things we are considering:

How much longer should we expect the form 2 to last and/or when will we begin to see performance issues. I’m not entirely sure how well it has been maintained. It was purchased before I started. However, the form 3b is maintained very well.

Is there anything else we should consider? How much is each valued at? How much money should they include with the transaction?
