The delay comes after it twice postponed its nine-month earnings before releasing unaudited results last month, stirring fears that its shares could be delisted from the Tokyo Stock Exchange

Meanwhile, its U.S. partner, California-based Western Digital Corp., is taking legal action to try to guarantee a say in who gets to buy the chip unit of Toshiba, its partner in a manufacturing joint venture. Western Digital, in turn, claims that the legal transfer of Toshiba's interests in its joint-venture to a subsidiary, Toshiba Memory, as part of the sale process violates the "anti-transfer provisions of the joint venture agreements", as it was done without the consent of Western Digital-owned SanDisk. Western Digital announced that it’s taking its fight with Toshiba to the International Court of Arbitration in San Francisco to stop the sale of its jointly operated memory-chip business without its consent. In the early hours of Monday, Western Digital said it had initiated arbitration procedures with the International Chamber of Commerce International Court of Arbitration, demanding Toshiba reverse a move to put its joint venture assets into a hived out entity – Toshiba Memory – and that it stop an all-out sale without consent from Western Digital unit SanDisk.
Western Digital appeals to arbitration in an effort to prevent its partner Toshiba, from selling its chip-making operation, Toshiba Memory.
