directors pick

I'm not quite sure whether this has been asked or not, but why haven't the directors of MIS endorsed one deal over the next? The board has recommended shareholders to accept both deals - that of SINO's offer and the new propsed merger.............and the directors haven't as yet(from my understanding) commited their personal holdings to either one. Won't this leave some holders confused as which way the board wants to sway????? Just asking???
I know when you do the maths the answer at the moment is evident.......is it beacuse they hope to make SINO stay in the game????
