HELSINKI--Stora Enso Oyj (STERV.HE) Tuesday said it will pay 22 million dollars to cover its share of a settlement that will close arbitration proceedings involving the Montes del Plata pulp mill project in Uruguay.

The Finnish paper, pulp and cardboard maker said the settlement payment will not have a material impact on its earnings. It will be recorded as capital expenditure in Stora Enso's second-quarter financial report.

The Montes del Plata mill, which started operations in 2014, is a joint venture between Stora Enso and the Chilean company Celulosa Arauco y Constitucion S.A. The joint venture was the target of arbitration proceedings started by a subsidiary of the Austrian plant engineering group Andritz AG (ANDR.VI) in 2014.

The parties to the arbitration have now signed an agreement that will end the proceedings. As a part of the agreement, Montes del Plata will make a $44-million cash payment to Andritz. Stora Enso's share of the payment is 50%.
