A piece of Erb Group's bank debt traded in the teens last week and European market players said there was more supply on the way. Erb has bank debt listed under its former divisions, which include Herfina, Unifina Holding, and Uniwood Holding. The Swiss conglomerate collapsed late last year and filed for protection from its creditors. Reports suggested that some financial improprieties were also committed. Officials from the Erb Group could not be reached by press time.
