"Arbitrarily" isn't the term that I would use, but ok.
What I am suggesting is that the size of the RME holding for those previous raises (I didn't doublecheck your count of 4, but I don't question it) was adequate so that, when added to the other holdings of MMSMFL, it resulted in a majority of the outstanding shares at the time of those elections.
For example:
At year end 8/31/08, per the 10K, holdings were as follows (millions, rounded):
MMSMFL 25
RME 257
Total O/S common shares 521
(Note that the individual ownership above is actually as of 7/28....this is for example purposes only and exact comparable data by date is tough to come by).
So, the common share election could result in a majority of all shareholders (54%) without even asking for the votes of any other than MMSMFL.
