The system failure, which shut down trading for around four hours in early November, was a major embarrassment for the exchange and was subsequently blamed on Fujitsu, the company who had recently upgraded its system. Mr Tsurushima said that the exchange was still trying to ascertain Fujitsu’s level of culpability, and once done it would consider whether or not to seek financial compensation.
Fujitsu has said it is investigating the incident and will soon decide if any of its staff should face disciplinary action for what occurred.
