Goldman Sachs will close the books a day early on the jumbo junk bond it is managing for Messer Griesheim, the German gases group, despite grumbles from investors about the deal's structure.

The €400m ($353m) bond offering was originally to be completed on Monday May 14. But on Wednesday afternoon Messer's management and bankers decided that they had already generated more than enough demand to complete and price the deal on Friday, said a source close to Messer. The bond will price to yield between 10.375% and 10.625%.
