UBS Investment Bank today announced that the ETRACS Natural Gas Futures Contango ETN (Ticker: GASZ), linked to the ISE Natural Gas Futures Spread? Index (the "Index"), has significantly outperformed the leading natural gas ETF, the United States Natural Gas Fund (Ticker: UNG), year-to-date, during the last 6 months and since both products could be purchased on an exchange.

GASZ is designed to capitalize on potential contango market environments typical to natural gas futures contracts. GASZ offers the potential to profit from the negative roll costs associated with the steepness in the short end of the natural gas futures curve, making it suitable for long-term investment horizons. Securities which fail to address the negative roll costs associated with contango markets lose value over time as investors are forced to repeatedly sell futures contracts at low prices and replace these with higher priced futures contracts.

As an ETN, GASZ also benefits from the elimination of index tracking error and avoids the tax administration burden associated with K-1 forms1. However, ETRACS ETNs are subject to investor fees, and therefore, the return on the ETNs will always be less than the return on a direct investment in the Index.

About the ISE Natural Gas Futures Spread? Index

The ISE Natural Gas Futures Spread? Index, through a series of investments in natural gas sub-indices, effectively provides short exposure in front month natural gas futures contracts and long exposure in mid-term natural gas futures contracts. This is achieved by taking a 100% long position in the components of the ISE Short Front Month Natural Gas Futures? Index, which provides short (or inverse) exposure to the ISE Long Front Month Natural Gas Futures? Index and an aggregate 100% long position in the components of the ISE Twelfth Month Natural Gas Futures? Index, ISE Thirteenth Month Natural Gas Futures? Index and ISE Fourteenth Natural Gas Futures? Index (33.33% per index), which provides long exposure to the mid-term Henry Hub Natural Gas Futures (NG) futures contracts. The Index is rebalanced monthly before the sub-indices' roll process to maintain the 1:1 long/short ratio.
