Eastmark Electrical Equipment Manufacturers needs to secure its supply of copper for the next year. The price of copper is extremely volatile because of huge month-to-month variation in demand. Eastmark wants to break even with a hedge against future copper prices. Currently, the market price for copper is reasonably low at $3.25 per pound or $325 (CWT).

Eastmark has also entered into a futures contract with a financial institution for 500,000 pounds per month at $3.25 per pound. CWT (hundredweight) is equal to 100 pounds in the United States. a.
