Hitachi Ltd.'s group operating balance may have returned to the black in the April-June quarter of the 2002 business year, according to Hitachi President Etsuhiko Shoyama.

Shoyama told Kyodo News in a recent interview that the firm would "make efforts to return to the black at the operating balance level" in the first three months of the current business year.

Hitachi is set to release its business results for the April-June period in its first quarterly results announcement in late July.
