Ecolab says received second request from DOJ for additional information

In a filing, Ecolab says it received a request for additional information and documentary material on November 9, often referred to as a "Second Request," from the United States Department of Justice in connection with its Hart-Scott-Rodino regulatory review of Ecolab’s proposed merger with Permian Mud Service, which was announced on October 12. Ecolab has been and will continue to work cooperatively with the DOJ and continues to expect the transaction to close by the end of 2012.
