As a reminder, FIDE fees have gone up from $35 per FIDE-rated section to $60 for events that end on or after June 1st.
The Board did discuss fees for FIDE Round Robin events at their May meeting, but I don’t recall if they took any action.
Based on recent exchange rates, the minimum fee the USCF has to pay FIDE for a FIDE rated Round Robin is around $77.70 and the fee for a high rated event like the Spice Cup would be $310.80.
