You must send your notice - no later than 2 days prior of the special meeting. At that point, they will review and calculate how many shares have been dissented. If you are eligibele to dissent all or partial of your shares, they will have that information before the special meeting.
I was not sure about this also until LAR released the clarification.
I thank all who contribute on these boards for the better of all shareholders.
