Around this time last year, in a magnanimous and expansive mood, i allocated both my adult children 10,000 HZRO's each. Far from normally that generous, i saw it as a good introduction to our share market, and just perhaps a chance to give them both a bit of a kick along in life.

As they sat in awe, I explained to them both that my kindness would also double as this year's Christmas present, and that i expected them to use the money wisely.
So now, as it nears time to cash in their bonanza, my question to the knowledgeable contributors here is;

Should I subtract the brokerage?
