ETFS 3x Daily Short Natural Gas (NG3S) is designed to enable investors to gain a three times 'short' exposure to a total return investment in natural gas futures contracts by tracking the Bloomberg Natural Gas Subindex (the "Index") and providing a collateral yield. A daily short exposure means that the product is designed to reflect minus three times the daily percentage change in the Index level. For example, if the Index was to rise in value by 5% on a particular day, the product is designed to decrease in value by 15% on that day (minus fees and expenses). NG3S is an exchange traded commodity ("ETC"). It is not a UCITS product. Securities in this ETC are structured as debt securities and not as shares (equity) and can be created and redeemed on demand by authorised participants and are traded on exchange just like shares in a company. The ETC is backed by swaps.
