IBKR will make voluntary corporate actions available for on-line election once all external terms including rates, eligibility restrictions and deadline dates have been confirmed with the depository or clearing agent. This verification process is manual and generally will take a few days after the initial announcement is made public.
Please note that if you have just purchased a stock that is part of a voluntary corporate action please allow up to 45 minutes for the Corporate Action Tool to update and reflect the voluntary offer.
In the event clients hold shares which they believe are eligible for a voluntary offer but the terms of which are not reflected through Client Portal make sure the correct account number is selected and if still missing, please contact IBKR Client Services via the Message Center.
