Can you explain what account will buyback SURGE? And will you buy it every day or once a week?

Will it be a market order on hive engine?

or buys from hive engine, liquidity pools and off chain?

Final question. Is it accurate to say the liquid yield that was owed to me as of Sunday at 0:00 UTC will not be paid in HBD?
The reason I'm asking is you are making an announcement today - and backdating its effective date by the sounds of it.
