ROE of 18% is excellent.
We have talked about ROE a long time ago on this thread.I think I compared Aussie banks ROE,and worked out 15% plus was the norm.
HNZ have first of all got to get over 10%,[which is one of their stated objectives as per Jeff Greenslade at last AGM].
They will achieve this,then I expect them to aim for 15% plus.
Longer term I expect they will be aiming for 18% .[plus?]
Then you could say we are "cooking with gas !".
Plenty for you to think about while planting your native trees.!!! lol.
