Could this be by any chance the "reconciliation process"....
I have the impression that this process refers to making sure the figures match... "que las figuras y los numeros concuerdan" and since this is an accountant's report, the closest to "concordatorio" in the accounting jargon could be "reconciliation"
concordar = to accord, to march, to agree, to conform, to reconcile... I believe in English it is the reconciliation process.
Just a thought.
Hope it helps.
