(collectively, the “PowerShares DB Crude Oil ETNs”) are the first United States exchange traded products that provide investors with a cost-effective and convenient way to take a long, short or leveraged view on the performance of an oil-based commodity index.
All of the PowerShares DB Crude Oil ETNs are based on a total return version of the Deutsche Bank Liquid Commodity Index—Oil, which is composed of certain crude oil futures contracts. The Long and Double Long ETNs are based on the Optimum Yield™ version of the Index, and the Short and Double Short ETNs are based on the standard version of the index.
