[1] On May 21, 2024, Franklin Resources Inc. (the “Seed Capital Investor”), an affiliate of the Sponsor, subject to conditions, purchased 4,000 Shares at per-Share price equal to $25.00 (the “Initial Seed Shares”). Delivery of the Initial Seed Shares was made on May 21, 2024. 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). Further, the transaction and other costs incurred in connection with the Seed Creation Units were paid by the Seed Capital Investor and not borne by the Fund.
