US Patent 7937316 Multi-basket structure for exchange traded fund (ETF)

A 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.
