For settlement of payments, GME determines the net position (debit or credit) of each selling and buying Participant towards GME on the basis of the amounts, including VAT where applicable, of the invoices issued and received by GME for the same invoicing period (single market session) whereas the following requirements are met:

• the invoice of the selling Participant is received by GME within the time limit set in the Technical Rules;
• the GME's invoice is received by the non-PA and PA buying Participant within the deadline set in the Technical Rules.

If this is not the case, GME defers the payments of the amounts, including VAT where applicable, at the time of receipt of the GME’s invoice by the Participant and of the Participant's invoice by GME.

GME, after the end of the reference session and within the time limit set in the Technical Rules:

• shall close the receivables due from its debtor Participants using their available deposit paid by the same participant up to its capacity;
• shall return the amounts paid as guarantee excess in relation to the purchases made in the session;
• shall settle the payables due to the vendors upon receipt of the invoice.

The payment will be made to the PA Participant net creditor within the working day following the determination of the net position.
