In down years 2011 and 2020, AJ made sure they were complete shockers by fully writing down the 747s and A380s respectively. This was signed off by auditors but it had the upside of making subsequent years look much better with significantly reduced depreciation expense. Hudson probably can't do this as even the most compliant auditor wouldn't allow the 787s to be written down and everything else if pretty much already fully depreciated. In fact, with new fleet arriving, she will have the opposite problem with depreciation expense growing massively as the new Airbus fleets arrive in the next few years.
