Exposure Netting.
Exposure netting involves offsetting exposures in one currency with exposures in the same or another currency, where exchange rates are expected to move in a way such that losses (gains) on the first exposed position will be offset by gains (losses) on the second currency exposure. This portfolio approach to hedging recognizes that the total variability or risk of a currency exposure portfolio will be less than the sum of the individual variabilities of each currency exposure considered in isolation. The assumption underlying exposure netting is that the net gain or loss on the entire currency exposure portfolio is what matters, rather than the gain or loss on any individual monetary unit.
