They will write it down (Bloom Lake, and other assets) to a value which they believe to be representative of what it is worth in the market. That way, if they then sell it for that same value, there will be no gain or loss on the transaction because the capital loss will already have been acknowledged by the Q3 write-down. The balance sheet would change in Q3 rather than at the time of the sale. If they write the asset down and then subsequently divest it for a different price than the new carry value, then a second capital gain or loss will be recognized at the time of sale. Hopefully, however, the sale price would be close to the level which the assets had been marked down to. The intent is to recognize that there's going to be a material loss eventually, and to recognize the loss immediately with the best possible estimate of what the loss will be. The company gets the bad news out of the way as soon as possible and brings the accounting back to what is hoped to be reflective of the true value/situation for the enterprise.
