Accounting Policies [Abstract] |
Basis of Presentation | A. Basis of Presentation The financial statements of the Trust have been prepared using U.S. GAAP. The Trust is considered an investment company under U.S. GAAP for financial statement purposes and follows the accounting and reporting guidance applicable to investment companies in the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification Topic 946, Financial Services— Investment Companies, but is not registered, and is not required to be registered, under the Investment Company Act of 1940, as amended.
Accounting Estimates | B. Accounting Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements. Actual results could differ from those estimates. In addition, the Trust monitors for material events or transactions that may occur or become known after the period-end date and before the date the financial statements are issued.
Segment Reporting | C. Segment Reporting The Trust represents a single operating segment. Subject to the oversight and, when applicable, approval of the Board of Managers, the Trust's Sponsor acts as the Trust's chief operating decision maker (“CODM”), assessing performance and making decisions about resource allocation within the Trust. The CODM monitors the operating results as a whole and the Trust's long-term strategic asset allocation is determined in accordance with the terms of its prospectus based on a defined investment strategy. The financial information provided to and reviewed by the CODM is consistent with that presented in the Trust's financial statements.
Cash and Cash Equivalents | D. Cash and Cash Equivalents The Trust defines cash as cash held by the Cash Custodian (as defined below). There were no cash equivalents held by the Trust as of September 30, 2025 and December 31, 2024.
Investment Valuations | E. Investment Valuations The Trust applies FASB ASC Topic 820, Fair Value Measurement, in the valuation of ether held by the Trust and for financial statement purposes. The fair market value price for ether reflects the price that would be received for ether in a current sale, which assumes an orderly transaction between market participants on the measurement date of ether on its “principal market,” generally, the most advantageous market. Market participants are defined as buyers and sellers in the principal or most advantageous market that are independent, knowledgeable, and willing and able to transact. The Trust determines its principal market (or in the absence of a principal market the most advantageous market) on a periodic basis to determine which market is its Principal Market for the purpose of calculating fair value for the creation of quarterly and annual financial statements. Issuer-specific events, market trends, bid/asked quotes of brokers and information providers and other data may be reviewed in the course of making a good faith determination of a security’s fair value.
Investment Transactions | F. Investment Transactions Ether transactions are accounted for on a trade date basis. Realized gains or losses from the sale or disposition of ether are determined on a specific identification basis and recognized in the Statements of Income and Expenses in the period in which the sale or disposition occurs, respectively.
Routine Operational, Administrative and Other Ordinary Expenses | G. Routine Operational, Administrative and Other Ordinary Expenses The Sponsor is responsible for all routine operational, administrative and other ordinary expenses of the Trust, including, but not limited to, the Trustee’s fees, the fees of the BNYM (the Administrator and the “Transfer Agent”) (for its services as the Administrator, Transfer Agent, and Cash Custodian (defined herein)), the fees of the Ethereum Custodian, the fees of Galaxy Digital Funds LLC (the “Execution Agent”), Exchange listing fees, SEC registration fees, printing and mailing costs, legal costs and audit fees. The Trust does not reimburse the Sponsor for the routine operational, administrative and other ordinary expenses of the Trust. Accordingly, such expenses are not reflected in the Statements of Income and Expense of the Trust.
Non-Recurring Fees and Expenses | H. Non-Recurring Fees and Expenses In certain cases, the Trust will pay for some expenses in addition to the Sponsor Fee (defined herein). These exceptions include expenses not assumed by the Sponsor (i.e., expenses other than those identified in Section G of this Note 2), litigation and indemnification expenses, judgments, transactional expenses, taxes and other expenses not expected to be incurred in the ordinary course of the Trust’s business. The only expenses of the Trust during the three and nine months ended September 30, 2025, the three months ended September 30, 2024 and the period June 17, 2024 to September 30, 2024 were the Sponsor Fee.
Federal Income Taxes | I. Federal Income Taxes The Sponsor intends to take the position that the Trust is properly treated as a grantor trust for U.S. federal income tax purposes. Assuming that the Trust is a grantor trust, the Trust will not be subject to U.S. federal income tax and, therefore, no provision for federal income taxes is required. Rather, if the Trust is a grantor trust, each beneficial owner of Shares will be treated as directly owning its pro rata share of the Trust’s assets and a pro rata portion of the Trust’s income, gain, losses and deductions will “flow through” to each beneficial owner of Shares.
