Keep as spare asset for whom? Do you know it still has 3 months value remaining?
If nobody use it within 3 month, it will be out of warranty again. We will not issue this desktop to any new users, as it is no warranty anymore.
It is not the first unit which is not reached to 3 years, keep as spare asset and wait for the day to write off. – is that the process you mentioned?
Anyway it’s not a big amount, I will proceed to submit for approval this time. But in all your decision making process (of course within in your scope), please think about all the financial impact.
