Toshiba says 'not ready', delays earnings, nuclear writedown

Toshiba Corp has unexpectedly delayed the release of its quarterly earnings and details of a multi-billion dollar writedown to its nuclear business, sending its shares sharply lower as investors fret over the conglomerate's future. Toshiba had said it would reveal the charge at noon, along with its latest outlook. Kyodo news agency, citing a financial source, said the delay was due to problems in Toshiba's discussions with auditors.
