PCC SE will submit a bid for majority of insolvent Romanian chemical producer Oltchim's assets, a source at the German firm said on Friday. The deadline for non-binding bids for packages of assets in the state-controlled company expires on January 23. The source said PCC, which owns 30% of Oltchim S.A. compared to the 54.8% owned by the state, would attempt to buy around 80% of the producer's overall assets. Romania has repeatedly attempted to privatise the financially troubled company without success.
