projectx is a poster who offered a very good technical response in the ato vs bbi thread.
I think the impairments were done for compliance with the accounting standards. Tax is not necessarily relevant to accounting profit or loss. I do believe however that there may be some losses carried forward and realised losses from the part disposal of Euroports.
The actual amount of losses will be affected by the outcome of the ATO vs BBI case. However, if BBI lose the cost base of DBCT will increase IMO reducing any gain on sale.
