I think Mitsui is not happy with the allocation to Bioamber Inc and they are reserving their right to recover a bigger piece of the pie. As they should. There is a reason why it was filed with the US Court, as BioAmber Inc., along with their Canadian subsidiaries, guaranteed the debt to Mitsui. http://www.sec.gov/Archives/edgar/data/1534287/000156459017015120/bioa-ex103_10.htm Mitsui wants their cut, both from the Canadian assets and from whatever funds BioAmber Inc. may receive from the sale of the US assets.
