A mining company has to remove and dismantle its extraction equipment when it has reached the end of its useful life. So the company has included an amount in its accounts for such costs and is depreciating this over the life of the asset.

An impairment review is taking place and the company has established the following:

• The carrying value of the extraction equipment in the statement of financial position is $6 million.

• An offer has been made for the equipment of $3 million (including taking over responsibility for its removal at the end of its life).

• The present value of the estimated cash flows from the assets continued use is $6.6 million.

• The carrying amount of the provision for dismantling the equipment is $1 million.

What is the impairment loss, if any, in $m?
