Class society DNV GL has become 100% Norwegian-owned five years after being formed through the DNV/GL merger.

The company said on Thursday that DNV Holding had agreed to buy the 36.5% controlled by Germany's Mayfair, owned by Gunter Herz and Daniela Herz-Schnoeckel, who were originally GL investors.

DNV told TradeWinds that the sale was not an option arising from the original merger agreement.
