It also means that the Trust will not utilize leverage. In order to track the Index as closely as possible, the Trust will aim to invest in the Index Constituents in the same proportions as the Index. Because the Trust’s investment objective is to track the price of the Index, the price of the Shares may vary from changes in the spot price of the Index Constituents. The Trust, the Sponsor, the Administrator and the service providers, including the Custodians, will not loan or pledge the Trust’s assets, nor will the Trust’s assets serve as collateral for any loan or similar arrangement. The Administrator calculates an approximate net asset value every 15 seconds throughout each day that the Trust’s Shares are traded on the Exchange. The Trust will not utilize leverage, derivatives, or any similar arrangements in seeking to meet its investment objective.
