True. But if we're having a bad year, reduce the life of those assets to 5 years. If you're gonna make a loss make it big. People will forget in 12 months anyway. Then you can revise again 12 months later and extend out that life, book a lower depreciation and voila, profit.
Mucking around with your depreciation rates to manipulate profit will get you caught out. That's why they report pre depreciation surpluses, but it's an important component of financial performance which is why they don't screw around with the rates.
But if the previous owners of Dick Smiths can get away with something similar, then the AFC should be fine. But no self respecting club board or CEO would. And there's no $500m payday at the end of it, just embarrassment.
