NEW YORK -- (Business Wire)

UBS Investment Banktoday announced coupon payments for four ETRACS exchange-traded notes (the “ETNs”), all traded on the NYSE Arca. The relevant coupon information is provided in the table below:

* “Current Yield” for each ETN equals the current Coupon Amount annualized and 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 ETNs. You are not guaranteed any coupon or distribution amount under the ETNs.

Note: RWXL, DVYL, SDYL and MORL pay a variable monthly coupon linked to 2 times the cash distributions, if any, on the respective underlying index constituents, less withholding taxes, if any. Variations in the amount of monthly distributions will lead to large variations in the Current Yield as calculated above. As such, the Current Yield for each is not indicative of future coupon payments, if any, on these ETNs.
