The mobile phone maker Sony Ericsson has posted a quarterly loss following disruption to its supply chain caused by the Japanese earthquake and tsunami.
The Swedish-Japanese joint venture, which is headquartered in London, revealed a €50m (£44m) loss for the three months to 30 June, compared with profits of €12m a year ago.
The company said the earthquake on 11 March disrupted its supply chain, with mobile phone shipments down 31 per cent to 7.6 million units.
Its chief executive, Bert Nordberg, said: "We estimate that the impact of earthquake-related supply-chain constraints on our portfolio was close to 1.5 million units, with most of the effect in the early part of the quarter." Smartphones accounted for 70 per cent of sales in the quarter.
