Name a common fee structure used by FGX for currency exchange services.

The chosen answer, which refers to transaction fees or service charges per remittance, accurately reflects a common practice in currency exchange services, including those offered by FGX. This fee structure is widely used because it directly aligns the cost with the customer's activity level; clients pay a fee each time they execute a transaction rather than incurring a flat fee that may not reflect how frequently they are using the service.

This fee model is advantageous for both the service provider and the customer. It provides transparency by allowing customers to understand exactly what they will be charged for each transaction, helping them to manage their expenses effectively. Additionally, because the fees are tied to the individual transactions, this structure can be more appealing to customers who may not engage in frequent exchanges, as they are not locked into a more substantial commitment in the form of monthly fees or asset management charges.

The other options describe less common or less relevant fee structures in the context of currency exchange. Monthly subscription fees can be inappropriate for services characterized by infrequent use, as most currency exchange needs are situational and do not lend themselves to a subscription model. Flat rates regardless of transaction size may not reflect the actual costs incurred by FGX, particularly as larger transactions often come with increased risk and operational costs. Lastly
