Answer:
The recognized loss is $10,000 and the basis of the new factory building is $450,000
Explanation:
The computations are shown below:
Gain or loss = Insurance proceeds received - the adjusted basis of the building
= $390,000 - $400,000
= ($10,000)
And, the basis of the new factory building would be $450,000 as it includes only construction cost
All other information which is given is not relevant. Hence, ignored it
