For the uninitiated like myself, could you please explain how this would work?

say I currently hold my shares with commsec, and I would like to elect to receive US newco shares.

If I understand correctly I would have to;

1. Submit the election form
2. open an account with a new broker, such as CMC as suggested by others
3. request a transfer of my shares from commsec to the new broker
4. do the above before 20 Dec (is this date correct)?

if I do all of the above, I will receive my newco US shares. Have I got that right?

sorry for asking, tracking down reliable info isn’t that easy!
