Perhaps convertable bond holders own lots of CDS on Decode and this is the reason that a deal to restructure the debt has been so elusive...

"CDSs are “anti-social”, he goes on, because those who buy credit insurance often have an incentive to see companies fail. Rather than merely hedging their risks, they are actively hoping to profit from the demise of a target company. This strategy became prevalent in recent years and remains so, as holders of these so-called “basis packages” buy both the debt itself and protection on that debt through CDSs, meaning they receive compensation if the company defaults or restructures. These investors “have an incentive to use their position as bondholders to force bankruptcy, triggering payments on their CDS rather than negotiate out of court restructurings or covenant amendments with their creditors”, Mr Einhorn says."
