TRELLEBORG, Sweden (March 2)—Trelleborg A.B. nearly has completed its $250 million acquisition of the BTR antivibration systems operations from Invensys P.L.C., but is awaiting approvals in Brazil and India, the Swedish firm said. Trelleborg had aimed to complete the deal formally on March 1. The outstanding approvals are expected to be obtained, although Trelleborg has received no indication when this will happen, a spokesman said. The Brazilian and Indian units account for less than 10 percent of the total sales of the former Invensys business, estimated at around $500 million, Trelleborg said.
