[1] The amount shown represents the NAV per share at commencement of the Fund’s investment operations. This amount includes proceeds to the Fund from the initial ether seed creation transaction conducted on June 27, 2024. Prior to June 27, 2024, 4,000 shares were acquired on May 21, 2024 at per share value of $25. Total proceeds to the Fund from the sale of the Initial Seed Shares were $100,000. On June 27, 2024, the Initial Seed Shares were redeemed for $100,000 and the Seed Capital Investor purchased two creation units in a cash transaction comprised of a total of 100,000 Shares at a per-Share price based on 380 ether per Creation Unit (or 0.0076 ether per Share), for a total of 760 ether (the “Seed Creation Units”). The cash proceeds to the Fund from the sale of the Seed Creation Units were used by the Fund to purchase 760 ether at the price of $3,446.37 per ether on June 27, 2024 (exclusive of transaction and other costs incurred in connection with the conversion of the cash proceeds to ether, which were paid by the Seed Capital Investor). Thus, the ultimate total proceeds to the Fund from the sale of the Seed Creation Units were $2,619,241.20 (an amount representing 760 ether).
