Personally, I am not concerned about this goodwill writeoff at all. As people have said, goodwill is a balancing asset in reality due to the fact FLC paid more for RWL than the net assets on its balance sheet. In theory, this amount represents the 'synergies' that have been purchased, however this asset doesn't exist in any tangible form. Thus, why not write off the amount? If you don't, you are just pretending that you have $56m in assets more than you actually do.
Further, writing it off now means that future profits are able to be presented as a profit, rather than $10m of write downs each year which may cause cash profits to be misleadingly shown to be a loss.

Moral of the story: it isn't a cash outflow, it doesn't necessarily show that RWL assets are underperforming, best to focus on the underlying numbers and the great growth that is present there. They are much more indicative of the company's future.
