I've been wondering the same thing. I don't really care about the short term effects of a stock split, but I'm holding MAT for my son so the more shares he can get while he is young, the better. I guess we will see. He's up 66% so far on this holding, so I am not going to complain!
I don't think that there is a stock split in the offering as of now. Maybe if it approaches or exceeds 75, which is well off. But in the meantime, the stock has been really really strong. Combined with the dividend, its been a nice winner for me.
