Looking at the type of services that derive those revenue, it falls under KYC and Payment Gateway.
I believe KYC services are a once off process that merchants do for each of their new customers and I believe it might be an annual recurring revenue due to the requirement to annually KYC your customers.
From the surface, apart from the KAB and Worldline issue, one would assume that majority of the KYC could've been processed through in May18 and June18 and it is not a monthly recurring event.
The timing of these does seem a little suspicious as it coincides with the performance shares deadline. One poster previously mentioned that they could've done a better rate/lower margin to sign merchants up for their KYC services to meet the target. That is a possibility.
