German engineering group Mannesmann AG, reporting horrible figures yesterday (see page seven) says that almost all its divisions were hit hard by weak demand and sales in the first half of 1993: Our profit collapse was due to weak sales and heavy price pressure in our mass production areas, negative currency movements and high restructuring costs, the company said; the electronics division lost money again due to weak sales in its mass production areas, and the only bright spot was telecommunications, which reduced its start-up losses due to the rapid growth of mobile phone sales by the Mannesmann Mobilfunk GmbH affiliate, which it now expects to break even next year the pace of growth is still very high, demand and sales are climbing fast with subscribers to the D2 network over 300,000, up from 220,000 at the end of April.
