Obviously, I don’t know, but it appears that Tri-Play (the Bucks) may have wanted to reduce their holding in the Phillies (i.e., wanted to move some of their money elsewhere), as, based on the reported ownership shares, this is a straight sale of a portion of the Tri-Play shares to Middleman.
Given that Middleton appears to have been looking for an additional limited partner since last year, we might infer that Tri-Play has wanted to get some money out for some time…and under the terms of the partnership, Middleton couldn’t just buy them out, because the partnership doesn’t permit any single entity to hold a majority stake.
By the way, long time no see, Fur_Coat!
