iPath Series B Carbon ETN

The iPath® Series B Carbon ETNs (the "ETNs") are designed to provide exposure to the Barclays Global Carbon II TR USD Index (the "Index"). The objective of the Index is to provide exposure to the price of carbon as measured by the return of futures contracts on carbon emissions credits from two of the world’s major emissions-related mechanisms (the “mechanisms” and each a “mechanism”). The mechanisms currently included in the Index are the European Union Emission Trading Scheme (“EU ETS”) and the Kyoto Protocol’s Clean Development Mechanism (the “CDM”). The Index is composed of allocations in futures contracts on a carbon emissions credit from each mechanism included in the Index (each such contract, an “Index Component”). The Index Components currently included in the Index are futures contracts that trade on the ICE Futures Europe exchange. The allocations of the Index to the Index Components are adjusted on an annual basis. While the weights may fluctuate over time, since the inception of the Index, the weight assigned to futures contracts associated with the EU ETS has been greater than 99.9%, and the weight assigned to futures contracts associated with the CDM has been less than 0.1%. Accordingly, the Index is heavily weighted toward futures contracts on carbon emission credits in the European Union.
