It depends. If you own stock as an individual only and own 2 classes, you will get 2 ballots.
But, if you own 2 classes in a Roth IRA, and 2 classes in a regular IRA, and 2 classes as an individual, you will get 6 ballots. I know. It happened to me last time.
You must vote each ballot and make a decision on the election.
If you hold P's and U's will you receive one ballot for each class?
