HKE and HKA are the same company to everybody except the HKCAD, who believe that they are seperate, sufficient to allow them to hold two AOCs.
HKA appears to be in it's death knells, even Dick Stew (one of the Singa toy boys) is reputed to be moving over to HKE as DFO. They could fold up HKA at any time, some are even suggesting that it would be a neat way for Hainan to dispose of a lot of debt. As for HKE, they appear to be a little bit better off than HKA.
Time will tell.
