UBS Investment Bank today announced a coupon payment for the ETRACS Alerian MLP Index ETN (NYSE Arca: “AMU”). The relevant coupon information is provided in the table below:

* "Current Yield (annualized)" equals the current Coupon Amount, multiplied by four (to annualize such coupon), divided by the closing price of the ETN on its current Coupon Valuation Date, or, if the closing price is not available on that date, then the previous available closing price, and rounded to two decimal places for ease of analysis. The Current Yield is not indicative of future coupon payments, if any, on the ETN. You are not guaranteed any coupon or distribution amount under the ETN.
