I left my class today unsatisfied over the discussion of impaired assets, and would like to get some opinions.
The asset is impaired if the book value is less than the future economic benefit. In that case the market value should be determined and the asset written down to the market value.
An example was a machine with a book value of $16,000, estimated future cash flow of $10,000, fair value of $9,000. $10,000 < $16,000, so a loss of $16,000-$9,000=$7,000 should be written off.
But I wonder what the heck does the market value have to do with it? If the estimated future economic benefit of the machine is $10,000, then the value of the machine to the company is $10,000. Writing off the difference between book and fair value seems like a statement that the company would be better off selling the machine than keeping it in production. But $10,000 > $9,000, so that would be wrong. What the company could get for the machine is not the $9,000 that someone else would pay for it, but the $10,000 from using it and running it into the ground.
I also wonder what it means that the book value includes the costs of transportation, installation, renovation, and everything else needed to make it ready for its intended use, while the fair value is what someone else would give you for it, and does not include those additional costs. I have the urge to consider the entire replacement or upgrade cost.
