Final answer:
The impairment loss recorded by Isa Company is $50,000.
Step-by-step explanation:
The impairment loss that should be recorded by Isa Company can be calculated as follows:
Carrying amount of the asset - Recoverable amount (lower of future net cash flows or fair market value) = Impairment loss
In this case, the carrying amount of the asset is $400,000 and the recoverable amount is $350,000 (fair market value). Therefore, the impairment loss is $400,000 - $350,000 = $50,000.
