RE: 3 questions about tendering to BEP 1). Yes, if bid fails, no share are bought by BEP at the offered price. They stay in your account.
2). If you tender now, BEP gets closer to closing the bid successfully, which when completed, guarantees the 2.60 payout for all shareholders who tendered.
3). You can wait, but if BEP bid fails, you are not getting 2.60.As a matter of fact, the share price may fall dramatically. So, read # 2 and tender.
