When a Bonus is declared and if you have open E-Margin (MTF) positions, the bonus shares are credited to your MTF balance, following are possible impacts to your account:

1) There is no impact on your open MTF position, however, the shares credited due to Bonus are auto pledged (As MTF Pledge), we urge you to monitor the margin due to additional shares

2) In certain cases, you maybe required to convert the position to delivery before the record date to get the benefit of the bonus
