(Telecompaper) Lenovo reported a net loss of USD 714 million for its fiscal second quarter to September, compared to a profit of USD 262 million a year earlier. The result included USD 599 million in restructuring costs and a USD 324 million one-time charge to clear smartphone inventory. Lenovo said it was on track to realise around USD 650 million in cost savings in the second half of the fiscal year and USD 1.35 billion on an annual basis. Quarterly revenues were still up 16 percent year-on-year to USD 12.2 billion and rose 23 percent excluding currency effects, while the gross margin fell to 13.0 percent from 13.9 a year ago. The sales growth was largely due to the acquisition of Motorola, which helped the Mobile Business Group double revenues year-on-year to USD 2.7 billion. Motorola contributed USD 1.4 billion in revenue. However, the MBG's posted a pre-tax loss of USD 217 million for the quarter. The PC Group saw revenues fall to USD 8.1 billion, and pretax profit was down 17 percent to USD 406 million. Lenovo said it suffered from currency fluctuations, hurting demand in the EMEA region and Brazil. The Enterprise Business Group, which includes servers, storage and software, recorded sales of USD 1.2 billion, up 5.5 times from a year ago thanks to the acquisition of IBM's System x business, which contributed USD 900 million in sales. The enterprise division still had a pretax loss of USD 33 million.
