During Project execution, subcontractors requested additional payments to cover increased costs. A funding deed(Deed) for the sum of A $757,727,884.46 was agreed and payed by the Plaintiff to the JV for the additional costs.
Subsequently, a dispute concerning the settlement of the additional costs arose, and an arbitration is being
conducted in Singapore. During the course of the arbitration, the Plaintiff demanded that the JV return the fullamount by the end of December 2020, but the JV refused on the grounds that the correct settlement procedures
under the Deed had not been followed and the arbitration award to determine this had not been made. Having
considered this, the Plaintiff delivered a letter dated January 15, 2021, to the parent companies of the JV, namelyChiyoda, JGC and KBR Inc. (Parent Companies), requesting the Parent Companies pay the identical amount tothe Plaintiff based on the parent company guarantee deeds.
