Toshiba chairman Shigenori Shiga has resigned,hours after the Japanese conglomerate revealed details of a multi-billion dollar loss, the BBC reports.
Earlier Toshiba had delayed issuing its results, and but it then said it was set to report a net loss of 390bn yen ($3.4bn) in the year to March 2017.
The company said it expected to select a 712.5 billion yen ($6.3bn,£5bn) writedown at its US nuclear business.
The situation has led some analysts to warn the company's future is at risk.
Mr Shiga was stepping down "to select management responsibility for the loss", the firm said.
Shares fell by as much as 9% on Tuesday and have lost approximately 50% since late December, or when it first warned approximately the extent of the problems.
The losses are linked to a deal done by its US subsidiary,Westinghouse Electric, when it bought a nuclear construction and services business from Chicago Bridge & Iron in 2015.
Assets that it took on are likely to be worth less than initially thought, and there is also a dispute approximately payments that are due.[br]
It has already announced plans to sell off fraction of its profitable memory chip business to raise funds. It is the second largest chip maker in the world,behind Samsung.
The company is still struggling to recover after it emerged in 2015 that profits had been overstated for seven years, prompting the chief executive to resign.
