Toshiba chief executive to resign over scandal

He will be succeeded by chairman Masashi Muromachi, with vice-chairman Norio Sasaki also stepping down.

On Monday, an independent panel appointed by Toshiba said the firm had overstated its operating profit by a total of 151.8bn yen ($1.22bn, £780m).

The overstatement was roughly triple an initial Toshiba estimate.

'Deeply apologise'

"It has been revealed that there has been inappropriate accounting going on for a long time, and we deeply apologise for causing this serious trouble for shareholders and other stakeholders," the company said in a statement.

"Because of this Hisao Tanaka, our company president, and Norio Sasaki, our company's vice chairman... will resign today."

Mr Tanaka, 64, and Mr Sasaki, 66, both joined Toshiba in the early 1970s.

Mr Sasaki served as Toshiba president between June 2009 and June 2013, covering most of the period during which the firm inflated the profits.

'Very regrettable'

Toshiba's accounting scandal began when securities regulators uncovered problems as they probed the company's balance sheet earlier this year.

The findings mean Toshiba will have to restate its profits for the period between April 2008 and March 2014. It is unclear whether it will affect the company's results for the year ending March 2015.

The finance minister, Taro Aso, said the case could undermine confidence in corporate governance in Japan.

He added the accounting irregularities at Toshiba were "very regrettable".

Japan's government has been trying to regain global investors' confidence with better corporate governance after Olympus, was found to have covered up $1.7bn in losses in late 2011, in what was until now Japan's worst corporate governance scandal.

'Corporate culture'

The report's findings are expected to lead to the restatement of earnings, a board overhaul and potentially hefty fines for Toshiba.

The inquiry found that the misreporting of profits began after the financial crash seven years ago, when senior managers began imposing unrealistic performance targets.

"Within Toshiba, there was a corporate culture in which one could not go against the wishes of superiors," the report said.

Therefore, when top management presented 'challenges', division presidents, line managers and employees below them continually carried out inappropriate accounting practices to meet targets in line with the wishes of their superiors."

Mr Tanaka and his predecessor Mr Sasaki are among eight high-level executives who have now resigned after the independent report found senior management complicit in a scheme to inflate profits over several years.

Regulators are believed to be starting their own review of Toshiba's book-keeping, based on Monday's report.

Shares in Toshiba rose 6% on the Nikkei stock exchange in Japan on relief that the report had few nasty surprises. But they are still down around 23% since Toshiba first disclosed cases of accounting irregularities in early April.
