JPMorgan has been ordered to pay billionaire Leonard Blavatnik $42.5 million damages in relation to a soured investment in mortgage-backed securities.

Blavatnik had sought to recover more than $100 million due to JPMorgan’s “alleged mismanagement” of his funds during the early stage of the housing crisis of 2007.

State Supreme Court Justice Melvin Schweitzer ruled that JPM had breached its contract with Blavatnik’s CMMF fund.
