How does Hedera address perceived or actual conflicts of interest between Hedera and individual Council members?

As noted in response to "Did Hedera pay council members to join the Council?", Hedera requires that any material transactions (those with a value of $100,000 or more) between a Council member and Hedera be reviewed and approved by the Board to prevent actual or perceived conflicts of interest or self-dealing.  Board members with an interest in the transaction must recuse themselves from such decision.
