Nomura Holdings Inc. will book ¥313 billion ($2.9 billion) in losses tied to the collapse of Archegos Capital Management, as Japan’s biggest brokerage vows to strengthen its risk management in the wake of the debacle.

Of the total, ¥245.7 billion ($2.3 billion) was logged in the three months ended March 31, leading to a quarterly net loss of ¥155.4 billion — its biggest since 2009. The remaining ¥62 billion will be booked in the current fiscal year, the Tokyo-based company said in a presentation Tuesday.

Nomura has exited over 97% of its positions with a U.S. client that Bloomberg understands to be Bill Hwang’s family office.
