Ann: WOTSO Demerger Complete, page-3

Firstly, note that I am not an accountant etc
My understanding is, but there can be exceptions, you need to hold 20% or more to equity account (probably what you're calling profit share). Hence BWF will simply get dividends and benefit from any rise in the share price just like any other WOTSO shareholder. Any management fees could be a flat dollar amount or percentage of the amount 'managed', though possibly (more likely?) WOTSO would employ BlackWall people directly. Either way, the 14% would have nothing to do with it.
Finally, note that I am not an accountant!
