Yes, ever since RHT started (and I bought in about 2002 or 3) they have regarded shareholders as nothing more than a tool to fund their work, which has been very good in their field. However they, as yet, have not seen any need to repay shareholders in any way or form.
I have recently re-entered in a minor way but have no intention moving back into the top 10, which I was 10 or 15 years ago.
