Resale of EC2 IRs

We took out a savings plan for our EC2 instances. It was no upfront fee and a 3 year commitment. We have a little less than 2 years left on the agreement. If we resell it on the marketplace how does that fee structure change. I assume:

• Since we paid $0 upfront we would receive no proceeds from the sale.
• Since the buyer will be paying a reduced rate to AWS we would be responsible for the delta between our current rates and theirs. Am I correct?
