Some explanation from the report
[QUOTE][While there are significant surpluses in Qantas Loyalty, Qantas Domestic and Qantas Freight CGUs, an impairment of $2,560 million arose in the stand- alone Qantas International CGU. The size of the impairment loss recognised is largely the result of wide body aircraft being purchased through a period where the Australian dollar was significantly weaker against the US dollar compared to recent years.
This impairment is a non-cash charge, with no impact on the economics of the business or change to cash flow forecasts. The impairment has arisen because Qantas International CGU has been tested as a standalone CGU for the first time. Accordingly the Qantas International fleet assets are not assessed in combination with the collective cash flows of the whole of Qantas’ operations. Following the impairment, the carrying value of Qantas International aircraft is more reflective of current market value./QUOTE]
