Subsequently Rio Tinto transferred and assigned to Turquoise Hill its right to seek reimbursement for these costs and fees from the Company. On January 20, 2021, the Company and Turquoise Hill entered into a settlement agreement, whereby Turquoise Hill agreed to a repayment schedule in settlement of certain secondment costs in the amount of $2.8 million (representing a portion of the TRQ Reimbursable Amount) pursuant to which the Company agreed to make monthly payments to Turquoise Hill in the amount of $0.1 million per month from January 2021 to June 2022. The Company is contesting the validity of the remaining balance of the TRQ Reimbursable Amount claimed by Turquoise Hill. As at September 30, 2022, the amount of reimbursable costs and fees claimed by Turquoise Hill (the "TRQ Reimbursable Amount") amounted to $6.4 million (such amount is included in the trade and other payables).
