A dispute is the result of one party disagreeing with a margin call from another. The dispute could be for the whole amount of the margin call, or only part of the value of the margin call. Disputes must be recorded, tracked and reported under global regulations. Each dispute involves each firm in reconciling the trades and positions they have with each others, the methods of calculation of exposure, the assets delivered to cover the exposure and their valuations, the valuations of each trade and any other inputs revenant. The end result should be a resolution to the dispute.
