The query you raised is more of a technical issue and is not a legal and/or contractual restriction of any manner whatsoever. To be clear - there is no issue with your entitlement over the stock you hold, and you are the beneficial owner of the shares at all times.
All of our clients’ shares are held in an omnibus account with IB, and as far as IB are concerned all shares are T212 clients’ shares, however, they do not distinguish between each individual client and his respective shares - only T212 maintains such records. So IB simply notes that we hold, say, 100 000 TSLA on behalf of our clients, but unfortunately for the time being we could only exercise the voting rights under all our clients’ shares altogether (as if we were the sole shareholder, as opposed to being able to exercise the voting rights under each share in line with the particular client’s voting instructions).
We are pushing to get a solution on this, but we cannot make any promises for the near future.
