Societe Generale de Belgique SA said Thursday it is ready to continue talks with Robert Maxwell that could result in the British publisher gaining a stake in Belgium's largest holding company. Maxwell and Societe Generale agreed in June to cooperate in creating a joint venture in communications, and the two sides had broached the possibility of Maxwell acquiring shares in Societe Generale. But the negotiations were interrupted when Maxwell turned his attention to Macmillan Inc., the New York-based publishing and information services company he has offered to acquire for $2.47 billion in cash. This week Macmillan agreed to a $2.5 billion cash-and-securities buyout by the investment firm Kohlberg Kravis Roberts & Co., but Maxwell said he was mulling his options. On Wednesday, Maxwell said he remained interested in acquiring a stake in Societe Generale and that talks may resume soon. A spokesman for Societe Generale said, ``We continue to be interested in having more international shareholders.'' Maxwell appears primarily drawn to Societe Generale's media interests, which are concentrated in Tractebel SA.
