Norway's DOF Group is attempting to calm a rebellion by small shareholders banding together to fight a refinancing plan that could all but wipe out their investments.

The Oslo-listed offshore vessel owner has previously warned that a long-term restructuring of $2bn of debt will involve a conversion of liabilities to shares, "significantly" diluting the holdings of existing investors.

The "DOF minority group" has been posting updates to the Oslo Stock Exchange under the names of investors Jim Oystein Holden and Jon Magne Asmyr.
