UBS AG's local unit placed an erroneous ¥3 trillion Capcom Co. convertible-bond order Wednesday that was subsequently canceled, the Tokyo Stock Exchange said.
UBS Securities Japan Ltd. placed the order for the convertible bonds and trading of the security was halted at 12:07 p.m., the TSE said.
UBS spokeswoman Jackie Kestenbaum wasn't immediately available for comment. Ryosuke Tanaka, a spokesman for the Japanese video game maker, said he couldn't immediately comment without verifying the situation.
"The trade in question was a cross transaction, so its impact should be limited," said Satoshi Mimura, a TSE spokesman.
The company originally sold ¥15 billion of the convertible bonds, due for redemption on March 31, in December 2001.
In July, a coding glitch forced Topix index futures to be suspended from trading for more than half a day, five months after a computer fault halted trading of the futures in Tokyo. Last March, trading in Alps Electric Co. and Nagoya Railroad Co. was halted because of a system problem.
