RE: A thought " the write down could have been done at a later quarter. There is window dressing going on."
It is not part of some master plan or conspiracy. It is an intangible number that all companies use to express many intangible things like the value that they think their good name is worth.
Once Yellow US (peer) was sold then that intangible was blown out of the water when the market put little to no real value on it. Once that happened YLO's accountants could no longer allow such a number to be used.
Bottom line, it was forced on them by the sale of Yellow in the States. It was not part of any master plan or conspiracy.
