UBS ETRACS Silver Shares Covered Call ETN SLVO Strategy

The investment seeks a return linked to the performance of the Credit Suisse NASDAQ Silver FLOWSTM 106 Index. The index measures the return of a “covered call” strategy on the shares of the iShares® Silver Trust (the “SLV Shares”) by reflecting changes in the price of the SLV Shares and the notional option premiums received from the notional sale of monthly call options on the SLV Shares less notional transaction costs incurred in connection with the covered call strategy.
