Ann: 80,000 BOE and $4.3M early revenue from new SWISH wells, page-61

I don't know but I don't think it's the case that the Australian Bank buys a fixed amount of stock then that stock trades as ADRs on the US market. They will use arbitrage to work out what to buy or sell and trade constantly.

Once the ADR rate is set, and let's pretend it's 10:1, so once consolidation is over BRK shares will be 50c and ADRs $5.

If there is demand for ADRs and the ADR price lifts up to $6 and the bank runs out of BRK to match with ADRs, then the bank will buy ASX stock on market up to $0.60c to match those orders and issue the ADRs to the holders who have bought them.

Same in reverse. If ADR sellers sell and the bank can sell on the ASX for more than anyone prepared to offer on the ADR market then that stock will flow back into the ASX pool and drop the price until it's matched.
