Answer:
$300,000 gain.
Explanation:
We will find the Barnett Corporation basis in the building = Cost - depreciation $900,000 - $600,000 = $300,000
When the office building is liquidated, the worth of the building is atleast the amount of liability that is assumed on the building. The building is subject to a $600,000 mortgage.
The liability assumed is $600,000;
To find out the gain Barnett Corporation must recognize,
= Liability - Barnett Corporation Basis
= $600,000 - $300,000 = $300,000.
Therefore, Barnett's gain is $300,000.
