There's not much difference to the driver, other than what Leo stated, but there are some differences from an accounting point of view of the paying party. They often go on different spots on the ledger, some companies use one as a fixed expense and the other as variable. Some customers have contracts in place for that reason, and to keep surcharges relatively stable, depending on the price of fuel rather than a percentage of the load. That's why we have it in expediting. Also, depending on the carrier and how they pay out, it can make a big difference to the driver. If the FSC is lumped into the overall pay, and they pay 60%, then they're only paying 60% of the FSC, as well.
