The following tables summarize activity in silver bullion for the six months ended June 30, 2020 and 2019:

On each business day, as soon as practicable after 4:00 p.m. (New York time), the net asset value of the Trust is obtained by subtracting all accrued fees, expenses and other liabilities of the Trust from the fair value of the silver and other assets held by the Trust. The Trustee computes the net asset value per Share by dividing the net asset value of the Trust by the number of Shares outstanding on the date the computation is made.

Trust Shares are issued and redeemed continuously in aggregations of 50,000 Shares in exchange for silver bullion rather than cash. Individual investors cannot purchase or redeem Shares in direct transactions with the Trust. The Trust only transacts with registered broker-dealers that are eligible to settle securities transactions through the book-entry facilities of the Depository Trust Company and that have entered into a contractual arrangement with the Trustee and the Sponsor governing, among other matters, the creation and redemption of Shares (such broker-dealers, the “Authorized Participants”). Holders of Shares of the Trust may redeem their Shares at any time acting through an Authorized Participant and in the prescribed aggregations of 50,000 Shares; provided, that redemptions of Shares may be suspended during any period while regular trading on NYSE Arca, Inc. (“NYSE Arca”) is suspended or restricted, or in which an emergency exists as a result of which delivery, disposal or evaluation of silver is not reasonably practicable.

The per Share amount of silver exchanged for a purchase or redemption represents the per Share amount of silver held by the Trust, after giving effect to its liabilities.

When silver bullion is exchanged in settlement of a redemption, it is considered a sale of silver bullion for accounting purposes.

The Trust is treated as a grantor trust for federal income tax purposes and, therefore, no provision for federal income taxes is required. Any interest, expenses, gains and losses are passed through to the holders of Shares of the Trust.

The Sponsor has analyzed applicable tax laws and regulations and their application to the Trust as of June 30, 2020March 31, 2021 and does not believe that there are any uncertain tax positions that require recognition of a tax liability.

The Trust pays to the Sponsor a Sponsor’s fee that accrues daily at an annualized rate equal to 0.50% of the net asset value of the Trust, paid monthly in arrears. The Sponsor has agreed to assume the following administrative and marketing expenses incurred by the Trust: the Trustee’s fee, the Custodian’s fee, NYSE Arca listing fees, SEC registration fees, printing and mailing costs, audit fees and expenses, and up to $100,000 per annum in legal fees and expenses.

The Sponsor and the Trustee are considered to be related parties to the Trust. The Trustee’s fee is paid by the Sponsor and is not a separate expense of the Trust.

The Trust Agreement provides that the Trustee shall indemnify the Sponsor, its directors, employees and agents against, and hold each of them harmless from, any loss, liability, cost, expense or judgment (including reasonable fees and expenses of counsel) (i) caused by the negligence or bad faith of the Trustee or (ii) arising out of any information furnished in writing to the Sponsor by the Trustee expressly for use in the registration statement, or any amendment thereto or periodic or other report filed with the SEC relating to the Shares that is not materially altered by the Sponsor.

The Trust Agreement provides that the Sponsor and its shareholders, directors, officers, employees, affiliates (as such term is defined under the Securities Act of 1933, as amended) and subsidiaries shall be indemnified from the Trust and held harmless against any loss, liability or expense incurred without their (1) negligence, bad faith, willful misconduct or willful malfeasance arising out of or in connection with the performance of their obligations under the Trust Agreement or any actions taken in accordance with the provisions of the Trust Agreement or (2) reckless disregard of their obligations and duties under the Trust Agreement.

The Trust has agreed that the Custodian will only be responsible for any loss or damage suffered by the Trust as a direct result of the Custodian’s negligence, fraud or willful default in the performance of its duties.

In the normal course of business, the Trust may enter into contracts with service providers that contain general indemnification clauses. The Trust’s maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Trust that have not yet occurred.

Substantially all of the Trust’s assets are holdings of silver bullion, which creates a concentration risk associated with fluctuations in the price of silver. Accordingly, a decline in the price of silver will have an adverse effect on the value of the Shares of the Trust. Factors that may have the effect of causing a decline in the price of silver include a change in economic conditions (such as a recession); a significant increase in the hedging activities of silver producers; significant changes in the attitude of speculators, investors and other market participants towards silver; global silver supply and demand; global or regional political, economic or financial events and situations; investors’ expectations with respect to the rate of inflation; interest rates; investment and trading activities of hedge funds and commodity funds; other economic variables such as income growth, economic output, and monetary policies; and investor confidence.

The following financial highlights relate to investment performance and operations for a Share outstanding for the three and sixmonths ended June 30, 2020March 31, 2021 and 2019.2020.

U.S. GAAP defines fair value as the price the Trust would receive to sell an asset or pay to transfer a liability in an orderly transaction between market participants at the measurement date. The Trust’s policy is to value its investment at fair value.

Various inputs are used in determining the fair value of assets and liabilities. Inputs may be based on independent market data (“observable inputs”) or they may be internally developed (“unobservable inputs”). These inputs are categorized into a disclosure hierarchy consisting of three broad levels for financial reporting purposes. The level of a value determined for an asset or liability within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement in its entirety. The three levels of the fair value hierarchy are as follows:

At June 30, 2020March 31, 2021 and December 31, 2019,2020, the value of the silver bullion held by the Trust is categorized as Level 1.

Introduction

The iShares Silver Trust (the “Trust”) is a grantor trust formed under the laws of the State of New York. The Trust does not have any officers, directors, or employees, and is administered by The Bank of New York Mellon (the “Trustee”) acting as trustee pursuant to the Second Amended and Restated Depositary Trust Agreement (the “Trust Agreement”) between the Trustee and iShares Delaware Trust Sponsor LLC, the sponsor of the Trust (the “Sponsor”). The Trust issues units of beneficial interest (“Shares”) representing fractional undivided beneficial interests in its net assets. The assets of the Trust consist primarily of silver bullion held by a custodian as an agent of the Trust responsible only to the Trustee.

The Trust is a passive investment vehicle and seeks to reflect generally the performance of the price of silver. The Trust seeks to reflect such performance before payment of the Trust’s expenses and liabilities. The Trust does not engage in any activities designed to obtain a profit from, or ameliorate losses caused by, changes in the price of silver.

The Trust issues and redeems Shares only in exchange for silver, only in aggregations of 50,000 Shares (a “Basket”) or integral multiples thereof, and only in transactions with registered broker-dealers that have previously entered into an agreement with the Sponsor and the Trustee governing the terms and conditions of such issuance (such broker-dealers, the “Authorized Participants”). A list of the current Authorized Participants is available from the Sponsor or the Trustee.

Shares of the Trust trade on NYSE Arca, Inc. under the ticker symbol SLV.

Valuation of Silver Bullion; Computation ofSilverBullion;ComputationofNetAssetValue

On each business day, as soon as practicable after 4:00 p.m. (New York time), the Trustee evaluates the silver held by the Trust and determines the net asset value of the Trust and net asset value per Share (“NAV”). The Trustee values the silver held by the Trust using the price per ounce of silver determined in an electronic auction hosted by ICE Benchmark Administration (“IBA”) that begins at 12:00 p.m. (London time) and published shortly thereafter, on the day the valuation takes place (such price, the “LBMA Silver Price”). If there is no announced LBMA Silver Price on any day, the Trustee is authorized to use the most recently announced LBMA Silver Price unless the Trustee, in consultation with the Sponsor, determines that such price is inappropriate as a basis for evaluation. The LBMA Silver Price is used by the Trust because it is commonly used by the U.S. silver market as an indicator of the value of silver and is permitted to be used under the Trust Agreement. The use of an indicator of the value of silver bullion other than the LBMA Silver Price could result in materially different fair value pricing of the silver held by the Trust, and as such, could result in different cost or market adjustments or in different redemption value adjustments of the outstanding redeemable capital Shares. Having valued the silver held by the Trust, the Trustee then subtracts all accrued fees, expenses and other liabilities of the Trust from the total value of the silver held by the Trust and other assets of the Trust. The result is the net asset value of the Trust. The Trustee computes NAV by dividing the net asset value of the Trust by the number of Shares outstanding on the date the computation is made.

Liquidity

The Trust is not aware of any trends, demands, conditions or events that are reasonably likely to result in material changes to its liquidity needs. In exchange for a fee, the Sponsor has agreed to assume most of the expenses incurred by the Trust. As a result, the only ordinary expense of the Trust during the period covered by this report was the Sponsor’s fee. The Trust’s only source of liquidity is its sales of silver.

CriticalAccountingPolicies

The financial statements and accompanying notes are prepared in accordance with generally accepted accounting principles in the United States of America. The preparation of these financial statements relies on estimates and assumptions that impact the Trust’s financial position and results of operations. These estimates and assumptions affect the Trust’s application of accounting policies. A description of the valuation of silver bullion, a critical accounting policy that the Trust believes is important to understanding its results of operations and financial position, is provided in the section entitled “Valuation of Silver Bullion;Bullion; Computation of Net Asset Value” above. In addition, please refer to Note 2 to the financial statements included in this report for further discussion of the Trust’s accounting policies.
