You asked...

"I wonder what those "obligations" are?"

AND THE ANSWER IS!?...

They are renegotiate DM'S Contingency Fee contract and keep them on Board, or buy them out...

That would be the ONLY OBLIGATION SAMSUNG has to address, beyond having reached a settlement agreement with EDIG, that would present enough complications which require the additional 30 days to be resolved...

Oh Baby...

Get ready to be Samsung Shareholders!?...Lol...Lol...
