RBS Securities Inc. (RBSSI) today announced the launch of the fourth exchange traded product in the growing suite of RBS TrendpilotTM Exchange Traded Notes (ETNs). The RBS Oil TrendpilotTM Exchange Traded Notes will be issued by The Royal Bank of Scotland plc (RBS plc) and will be listed on NYSE Arca, Inc. under the ticker “TWTI.”

The ETNs are designed for investors who seek exposure to the RBS Oil TrendpilotTM Index (USD) (the “Index”), which tracks either the RBS 12-Month Oil Total Return Index (the “Benchmark Index”), or the yield on a hypothetical notional investment in 3-month U.S. Treasury bills (the “T-Bill Rate”), depending on the relative performance of the Benchmark Index on a simple historical 100-day moving average basis. The Benchmark Index tracks twelve (12) light sweet crude oil (WTI) futures contracts, traded on the New York Mercantile Exchange (“NYMEX”), that are scheduled to expire in the immediately following calendar month and each of the eleven calendar months thereafter. The Benchmark Index is rebalanced on a monthly basis so that each of the twelve (12) futures contracts is equally weighted upon each rebalancing.

Payment on the ETNs is linked to the performance of the Index, less an investor fee that is deducted daily at an annualized rate of 1.10% if the Index is tracking the Benchmark Index or an annualized rate of 0.50% if the Index is tracking the T-Bill Rate. Investors have the right to require RBS plc to repurchase the ETNs on a daily basis, subject to a minimum repurchase requirement. RBS plc, at its sole discretion, may also redeem the ETNs at any time prior to maturity.

“The RBS Oil TrendpilotTM ETNs, like the other ETNs in our TrendpilotTM suite, are designed for investors who seek an objective and transparent trend-following strategy that aims to mitigate, to some extent, the volatility of investing in oil.” said Michael Nelskyla, Head of Structured Retail Distribution, Americas.
