European Commission will push back the deadline for ending its investigation into whether IBM's planned acquisition of Telelogic breaks EU competition rules European competition regulators said Tuesday that they have stopped the clock in their in-depth investigation into IBM’s planned $745 million takeover of Swedish software maker Telelogic.The European Commission, Europe’s top competition authority, has asked the companies for more information about the deal in order to assess whether it breaks European Union competition rules.The Commission was due to conclude its investigation by a Feb. 20 deadline. A later date will be set once all the required information has been submitted, a Commission official said, asking not to be named. The Commission opened a probe of the deal after reaching the preliminary conclusion that the acquisition would cause competition problems. The companies compete head-on in the areas of software modelling and building development tools.If they join forces, this “could have adverse effects on competition,” the Commission said.Telelogic has customers mainly in the aerospace and defense, telecommunications, and automotive industries. IBM said when it announced the planned deal that the tie-up would give its clients a wider range of software and system development capabilities. If the deal is approved, Telelogic will become part of IBM’s Rational Software unit. Technology Industry
