A US importer, who incurs costs in Euro's and bills its customers in USD, is concerned about the depreciation of USD against Euro due to EURO payables of 10,000,000 in a month. To hedge (protect himself/herself) the position, importer decides to use futures markets. Currently EURO contracts (125,000 EURO each) are traded at $0.8470. Spot rate is $0.8310 (ie EUR/USD 0.8310). Suppose the importer takes an equal futures position to its cash market position (Euro10m) at $0.8470. Assume that futures contract price and spot rates are $0.8600, $0.8540 respectively when the hedge is liquidated. What should be the unit cost of EURO for the importer in terms of USD?

	A)	0.8600
	B)	0.8540
	C)	0.8670
	D)	0.8410
