You will get an email from whichever broker you are using and it will have a link that will take you to a web portal. It knows who you are based on your control id. ** Don’t give that out to anyone **
It’s just a few questions with for/against choices for you to vote on. You make your choices, click submit, and that’s it.
There will also be links to proxy materials in the portal that explain what each item you are voting on is all about. That will give you more details so you can make a more informed decision. Might want to read over those first before you vote.
And yes, the question of “can I change my vote” always comes up. Yes you can as long as the voting window hasn’t closed yet. You would just click on the same link in the email, make your choices, and then submit again.
