Integrated circuit manufacturer QPL International Holdings is expected to raise prices to maintain profit margins after a surge in copper costs. Unveiling a net loss of $29 million for the six months to October last year against a loss of $123 million in the corresponding period in 2004, chief executive Joe Martin said recent developments in the semiconductor industry facilitated adjustments in pricing. Mr Martin said rising copper prices had left customers hesitant to build up inventory and caused a decline in QPL's sales. Time was required to pass the increased copper costs on to customers and net material costs to sales had increased slightly. QPL's share of losses at associate Asat Holdings was $6 million, which represented the attributable fair value of warrants acquired with its participation in the financing of Asat, it said. The firm also said it had stopped recognition of its share of losses of Asat since the second half of the financial year to April. The unrecognised share of losses for the period and cumulatively amounted to $67 million and $146 million. Asat reported an interim net loss of US$19.4 million under United States accounting standards, against a net loss of US$14.5 million previously. Net sales dropped 18 per cent mainly due to a decline in average selling prices and a shift in production mix but improvements were seen in the second quarter to October last year.
