| 20110196777 | MULTI-BASKET STRUCTURE FOR EXCHANGE TRADED FUND (ETF) - An exchange-traded fund (ETF) has a multi-basket structure that allows shares of the ETF to be created using a different basket of assets than the basket of assets required to redeem shares of the ETF. A method for administering a multi-basket ETF comprises providing shares of the ETF to investors in exchange for assets defined in a published creation basket, providing assets defined in a published redemption basket to investors in exchange for shares of the ETF, and publishing a holdings basket that represents the assets held in the ETF. The multi-basket ETF can be used to implement an ETF holding assets that have a relatively low liquidity and/or accessibility. The multi-basket structure also enables financial strategies such as to minimize transaction costs, increase tax efficiency, access less liquid or less accessible markets or securities, and meet regulatory requirements and ETF investment objectives. | 08-11-2011 |
| 20100174664 | ETF Trading in Secondary Market Based on Underlying Basket - A trading system enables investors to execute trades electronically on exchange at prices that are chosen in consideration of the derivative nature of ETFs as a portfolio of securities or other financial instruments. In addition to measuring liquidity in the ETF itself on exchange, the trading system analyzes the liquidity of the ETF's underlying portfolio to understand the liquidity that is available to investors in the ETF through the creation/redemption process. By monitoring the bid/ask spread of both the ETF and the underlying portfolio in real time, the trading system enables investors to leverage the full potential liquidity of ETFs. The trading system can be used to manage the data and pricing infrastructure for identifying these liquidity replenishment points and to make these prices actionable for investors. | 07-08-2010 |
