UBS Announces the 16th ETN in its E-TRACS Platform Which Gives Short Exposure to the Alerian MLP Infrastructure Total Return Index

UBS Investment Bank announced today the addition of a new exchange traded note (ETN) to its E-TRACS platform, the UBS E-TRACS 1X Monthly Short Alerian MLP Infrastructure Total Return Index. It is the 16th ETN in UBS’s rapidly growing E-TRACS platform, and the fourth ETN with Alerian. It began trading today on NYSE Arca under the ticker symbol, MLPS, and is designed to provide short exposure to the Master Limited Partnership (MLP) market by tracking the inverse performance of the Alerian MLP Infrastructure Total Return Index.

“This is our fourth ETN with Alerian and expands even further our spectrum of MLP ETN choices, giving investors an easily accessible, exchange-traded vehicle to hedge their exposure to the Master Limited Partnership market,” said Christopher Yeagley, Managing Director and US Head of Equity Structured Products. “We are proud of the diversity of our E-TRACS platform and are excited that we can continue offering investors interesting and useful products.”

UBS E-TRACS belong to an innovative class of investment products offering access to markets and strategies that had not previously been readily available to investors, and offer unique diversification opportunities in a number of different sectors.

UBS has 15 other existing E-TRACS ETNs – 10 that track the performance of various UBS Bloomberg CMCI indexes, like platinum, silver, gold, livestock, food, etc; one that tracks the total return of the Dow Jones-UBS Commodity Index; one that is linked to the S&P 500 Gold Hedged Index; one linked to the Alerian MLP Infrastructure Index; one that offers 2x leveraged exposure to the Alerian MLP Infrastructure Index; and one linked to the Alerian Natural Gas MLP Index.

The Alerian MLP Infrastructure Total Return Index is comprised of 25 energy infrastructure MLPs whose constituents generally earn the majority of their cash flow from the transportation and storage of energy commodities. This index provides investors with a benchmark for the infrastructure component of this emerging asset class.

UBS E-TRACs are senior unsecured notes issued by UBS AG, are traded like any other security on NYSE Arca, and can be bought and sold through a broker or financial advisor. For more information about UBS E-TRACs, please visit www.ubs.com/e-tracs.
