Ann: 2016 AGM Presentation, page-69

Definitely exceeded 20%p.a. For first 13 yrs (accountant verified) , but last 3 or so will come back to the field a bit I reckon.
I admire those who have a more targeted approach , but my "system" seems to work o.k.

20%pa for over 13 years means your "system" is working just fine.
Congratulations.
(Just make sure you aren't taking on too much risk that could result in an irretrievable blow-up that does permanent damage.)

Can I ask what sort of companies you have been invested in?


"Yes..gets harder the more money u get in there.."

Surely unless you have several tens of millions of dollars deployed, that shouldn't be an impediment to performance?
