Final answer:
The impairment would be recorded as a loss of $25 million.
Step-by-step explanation:
The impairment would be recorded as a loss of $25 million.
When the fair value of an asset is less than its book value, it indicates that the asset has decreased in value. In this case, the fair value of Bonnaroo stages is estimated to be $5 million, which is $25 million lower than its book value of $30 million. Therefore, the impairment would be recorded as a loss of $25 million to reflect the decrease in value.
