(2)PSPs may choose to set charges on a per transaction basis either in nominal terms or as a percentage of the value of the transaction. PSPs may also opt for alternative charging structures, including tiered pricing based on different bands of the transaction value or approaches that have a certain number of transactions per month for free beyond which a charge per transaction is applied. It would be undesirable that such heterogeneity of commercial practices results in the circumvention of the aim of the rule on the charges for instant credit transfers laid down in Article 5b(1) of Regulation (EU) No 260/2012. The methodology for reporting the information on the level of charges for regular and instant credit transfers should enable the Commission to evaluate the information provided by PSPs in a uniform and comparable manner at the level of a PSP over time and among different PSPs at a given point in time, despite the different charging methods used by PSPs. The reporting should therefore contain the information on the total aggregated charges, volume and value of credit transfers, including instant credit transfers, in the national currency. The reporting on credit transfers, both sent and received, should also include a breakdown by free and paid-for credit transfers.
