I pretty much do same as what I would do on the face, I see more gals who just don't ever exfoliate the back, and a few with acne. If it's mainly dead skin buildup I will use a good exfoliateing scrub-like salt/sugar etc., with acne, I will use either a 1-2 layer peel or emzyme peel followed by extractions.
For forward contracts, settlement of the contract occurs at the end of the contract. Futures contracts are marked-to-market daily, which means that daily changes are settled day by day until the end of the contract. Furthermore, settlement for futures contracts can occur over a range of dates.
Use forward contracts as a way to hedge against currency drops and spikes. Like any derivative, a forward contract is a great way to ensure you don't lose a lot of money if a currency you have a sizable position in drops in value.
