About the Index

The Index is a liquid, midstream-focused subset of the Alerian MLP Index comprised of 25 energy infrastructure MLPs. The Index, whose constituents generally earn the majority of their cash flow from the transportation and storage of energy commodities, provides investors with a benchmark for the infrastructure component of this emerging asset class. The Index is calculated using a capped, float-adjusted, capitalization-weighted methodology that results in greater diversification versus a pure market capitalization-weighted index.

MLPI offers:
  • Exposure to a portfolio of 25 energy infrastructure MLPs through a single, exchange-traded security
  • Income via quarterly coupons linked to cash distributions, if any, paid by the MLPs in the Index, less fees 1
  • No K-1s: the coupons associated with the ETN are reported as ordinary income on Form 1099, and therefore the administrative burden associated with K-1 forms is eliminated 2.

Exchange Traded Access Securities, ETRACS, are exchange-traded notes (ETNs), an innovative class of investment products offering access to markets and strategies that may not be readily available to investors, and offer unique diversification opportunities in a number of different sectors. ETNs offer:
  • Access to asset classes with historically low correlations to more traditional asset classes
  • Convenience of an exchange-traded security
  • Transparent exposure to a published index

ETRACS ETNs are senior unsecured notes issued by UBS AG (“UBS”), are traded on NYSE Arca, and can be bought and sold through a broker or financial advisor. An investment in ETRACS ETNs is subject to a number of risks, including the risk of loss of some or all of the investor’s principal, and is subject to the creditworthiness of UBS. Investors are not guaranteed any coupon or distribution amount under the ETNs. We urge you to read the more detailed explanation of risks described under “Risk Factors” in the prospectus supplement for the ETRACS ETN.

1 Quarterly coupons are linked to the cash distributions, if any, paid by the MLPs in the Index, less fees. If the MLPs do not make distributions, or these distributions do not overcome the investor fees, the investor will not receive any coupons. You are not guaranteed any coupon or distribution amount under the ETN.

2 Significant aspects of the tax treatment of the ETNs are uncertain. You should consult your own tax advisor about your own tax situation.
