BERLIN - German shipper Hapag-Lloyd swung to a first-quarter profit thanks to the stronger U.S. dollar, lower bunker fuel prices and first effects from its merger with Chilean shipper CSAV. The company on Wednesday posted a net profit of 128.2 million euros in the first three months of the year, against a loss of 119.1 million one year ago. “This is a solid start to the year, in spite of the continued price pressure in many of the trades,” Chief Executive Rolf Habben Jansen said in a statement.
