Alcoa official sources specified yesterday that at the end of this week will inform the monitoring commission of the ERE (dossier of employment regulation) and the Ministry of Industry on the binding offers of potential buyers of the plants of A Coruña and Aviles (Asturias ). Waiting to know the finalist proposals, so far there are six investors who opt for the purchase. Only half of them offer a future for the Coruña factory. The British Liberty House «owner of several factories of the leading steelmaker ArcelorMittal», the private equity company Parter and the Spanish Riesgo (IR Group) aspire to take over the ownership of the two factories in batch, which would mean maintaining 100% of the employment in both. However, Aludium, Quantum and Cunext transferred to the US multinational its interest in developing its industrial activity only in Avilés, which is why the Asturian factory enjoys a more advantageous position in the sales process. The ERE marks the 30th of this month as the deadline for the sale. Otherwise, collective dismissal would be executed.
