The Fund seeks to provide investment results that, before fees and expenses, track the performance of the Index. The Index is a rules-based, equal-weighted index that tracks the performance of the top 100 U.S.-listed ETFs. For this purpose, the term ETFs means exchange-traded investment vehicles, including exchange-traded funds that are registered as investment companies under the Investment Company Act of 1940, as amended (the 1940 Act) and exchange-traded vehicles that are not subject to the registration requirements of the 1940 Act, such as grantor trusts. The Index selects the 100 top ETFs based on a proprietary methodology that ranks eligible ETFs according to size, liquidity and risk-adjusted returns. The Fund uses a replication indexing strategy, which means that the Fund will invest in all or substantially all of the ETFs in the Index such that, after each quarterly rebalancing, 1% of the Funds assets will be invested in each of the 100 ETFs represented by the Index. In certain circumstances, when it is not possible or practicable to purchase or hold an ETF included in the Index to the same extent as represented by the Index due to potentially adverse tax consequences of that ETF or due to other Fund policies or restrictions, the Fund may adjust the Funds holdings such that the Funds weights may deviate from the weights of the Index to the extent necessary to avoid such adverse tax consequences or otherwise comply with Fund policies or restrictions. The ETFs in which the Fund invests are referred to herein as the Underlying ETFs.
