LONDON (Dow Jones)--Translation services company SDL PLC (SDL.LN) Thursday said it agreed to buy an automatic translation software company for $42.5 million, in a deal that will allow its customers to translate larger volumes of online content quicker. SDL said the cash purchase of Los Angeles-based Language Weaver Inc. will reduce earnings in 2011 because of amortization charges but will boost earnings in future years. -By Jason Douglas, Dow Jones Newswires; 44-20-7842-9272; [email protected] (END) Dow Jones Newswires July 15, 2010 02:28 ET (06:28 GMT)
