Toshiba today filed twice-delayed business results without an endorsement from its auditor and warned its very survival was in doubt, deepening a prolonged crisis at the Japanese conglomerate.
"There are material events and conditions that raise substantial doubt about the company's ability to continue as a going concern," Toshiba said in announcing bigger than previously estimated losses for the nine months through December.
The filing carried a disclaimer from auditor PwC that it was unable to form an opinion of the results, increasing the likelihood that shares in the nuclear-to-TVs company will be delisted from the Tokyo Stock Exchange (TSE).
The move is a first for a major Tokyo-based firm, and puts the stock exchange centre stage as it weighs the pros and cons of forcing Toshiba to delist.
Toshiba chief executive Satoshi Tsunakawa expressed regret that the auditor could not form an opinion, and said Toshiba pressed ahead with submitting its results rather than seek an unprecedented third delay.
"The decision on any delisting is for the stock exchange to make," he told a news conference in Tokyo, the latest in a string of briefings that have opened with apologies to shareholders.
"We will do our utmost to avoid it."
Failing to act tough with Toshiba would bring into question authorities' credibility in maintaining standards for investors, but a delisting would complicate the crisis at Toshiba, increasing its financing costs and exposing it to further lawsuits from angry shareholders.
Accountants have been questioning the numbers at US nuclear subsidiary Westinghouse Electric, where massive cost overruns at four nuclear reactors under construction in the Southeastern United States have forced its Japanese parent to estimate a US$9 billion annual net loss and take drastic measures.
PwC is questioning not only recent results, but also probing the books at Westinghouse for the business year through March 2016, sources have said, declining to be identified as they were not authorised to speak on the matter publicly.
The decision on whether or not to delist Toshiba now rests with the TSE. Toshiba has been on its supervision list since mid-March after failing to clear up concerns about its internal controls a year and a half after a 2015 accounting scandal.
There are no set rules governing how long the bourse should take to come to a conclusion.
Toshiba has put up its prized memory chip unit and other assets for sale, and Westinghouse has filed for Chapter 11 protection from creditors.
Toshiba also today said it was considering an initial public offering or sale of smart meter group Landis+Gyr. Reuters last month reported that Toshiba was preparing a potential US$2 billion divestment of the Swiss-based business.
