REA Certification

We recently submitted an REA which was approved, but we need to certify the REA in accordance with 252.243-7002.  The company officer who signed the contract and all contract mods seems to think there is a requirement that the CFO certify the REA.  The DFARs simply says "an individual authorized to certify the request on behalf of the Contractor."  Can you guys give me some input on this?  I would think if the VP is authorized to sign the original contract and the contract mods that he would be an authorized party on behalf of the Contractor.
