Once you place your vote preference it will be sent to the fund manager (who usually holds the legal right to vote). Your fund manager will see how everyone on Tumelo's platform voted (e.g. 80% in favour and 20% against) and take it into consideration when voting at the AGM.
This means that they won't necessarily vote how Tumelo users voted. They also have to consider other factors as well, such as how the vote will impact the performance of the pension or investment fund. Once your fund manager makes a decision, they will then place a legal vote at the company AGM.
The final result is decided based on the votes of all direct shareholders, including your fund manager's. Each vote has a different pass threshold and carries different effects if passed. For example, some votes are only advisory rather than binding, and may need more than the usual 50% threshold to be passed.
