1 - Organization

The iShares^® Silver Trust (the “Trust”) was organized on April 21, 2006 as a New York trust. The trustee is The Bank of New York Mellon (the “Trustee”), which is responsible for the day to day administration of the Trust. The Trust’s sponsor is BlackRock Asset Management International Inc. (the “Sponsor”), a Delaware corporation. The Trust is governed by the Depositary Trust Agreement (the “Trust Agreement”) executed at the time of organization of the Trust by the Trustee and the Sponsor. The Trust issues units of beneficial interest (or “Shares”) representing fractional undivided beneficial interests in its net assets.

The objective of the Trust is for the value of its Shares to reflect, at any given time, the price of silver owned by the Trust at that time, less the Trust’s expenses and liabilities. The Trust is designed to provide a vehicle for investors to own interests in silver bullion.

The accompanying unaudited financial statements were prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions for Form 10-Q and the rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”). In the opinion of management, all material adjustments, consisting only of normal recurring adjustments, considered necessary for a fair statement of the interim period financial statements have been made. Interim period results are not necessarily indicative of results for a full-year period. These financial statements and the notes thereto should be read in conjunction with the Trust’s financial statements included in its Annual Report on Form 10-K for the year ended December 31, 2011 as filed with the SEC on February 29, 2012.

The Trust is not an investment company registered under the Investment Company Act of 1940, as amended.

2 - Summary of Significant Accounting Policies

The following is a summary of significant accounting policies consistently followed by the Trust in the preparation of its financial statements in conformity with U.S. GAAP. The preparation of financial statements in conformity with U.S. GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates and these differences could be material.

JPMorgan Chase Bank N.A., London branch (the “Custodian”), is responsible for the safekeeping of silver bullion owned by the Trust.

For financial statement purposes, the silver bullion held by the Trust is valued at the lower of cost or market, using the average cost method. Should the market value of the silver bullion held be lower than its average cost during the interim periods, an adjustment (“market value reserve”) to cost may be recorded by the Trust to reflect market value. At the end of the Trust’s fiscal year, management will make a determination on whether the reserve is recovered or whether the cost basis of silver should be written down. Gain or loss on sales of silver bullion is calculated on a trade date basis. Fair value of the silver bullion is based on the price for an ounce of silver set each working day by three market making members of The London Bullion Market Association (“London Fix”).

Shares of the Trust are classified as “redeemable” for balance sheet purposes, since they are subject to redemption. 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 eligible to settle securities transactions through the book-entry facilities of the Depository Trust Company and which have entered into a contractual arrangement with the Trust 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 is calculated daily by the Trustee, using the London Fix to calculate the silver amount in respect of any liabilities for which covering silver sales have not yet been made, and represents the per Share amount of silver held by the Trust, after giving effect to its liabilities, sales to cover expenses and liabilities and any losses that may have occurred.

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

Table of Contents

Due to the expected continuing sales and redemption of capital stock and the three-day period for Share settlement, the Trust reflects capital Shares sold as a receivable, rather than as contra equity. Shares redeemed are reflected as a contra asset on the trade date. Outstanding Trust Shares are reflected at redemption value, which is the net asset value per Share at the period ended date. Adjustments to redemption value are reflected in shareholders’ equity.

Net asset value is computed by deducting all accrued fees, expenses and other liabilities of the Trust, including the Sponsor’s fees, from the fair value of the silver bullion held by the Trust.

Activity in redeemable capital Shares was as follows (all balances in 000’s):

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 and gains and losses are deemed “passed through” to the holders of Shares of the Trust.

3 - Trust Expenses

The Trust pays to the Sponsor a Sponsor’s fee that accrues daily at an annualized rate equal to 0.50% of the adjusted 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.

4 - Related Parties

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.

5 - Indemnification

Under the Trust’s organizational documents, the Sponsor is indemnified against liabilities or expenses it incurs without negligence, bad faith or willful misconduct on its part. 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.

6 - Concentration Risk

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), an increase in the hedging activities of silver producers, and changes in the attitude towards silver of speculators, investors and other market participants.

7 - Subsequent Events

In connection with the preparation of the financial statements of the Trust as of and for the period ended March 31, 2012, management has evaluated the impact of all subsequent events through the date the financial statements were issued and has determined that there were no subsequent events requiring adjustment or disclosure in the financial statements.

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 Depositary Trust Agreement (the “Trust Agreement”) between the Trustee and BlackRock Asset Management International Inc., the sponsor of the Trust (the “Sponsor”). The Trust issues units of beneficial interest (or “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 the objective of the Trust is for the value of each Share to approximately reflect, at any given time, the price of silver owned by the Trust less the Trust’s liabilities (anticipated to be principally for accrued operating expenses) divided by the number of outstanding Shares. 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 or integral multiples thereof (each, a “Basket”), and only in transactions with registered broker-dealers that have previously entered into an agreement with the Trust governing the terms and conditions of such issuance (such broker-dealers, the “Authorized Participants”). A list of current Authorized Participants is available from the Sponsor or the Trustee.

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

Valuation of Silver; Computation of Net Asset Value

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 the net asset value per Share. The Trustee values the silver held by the Trust using the announced price for an ounce of silver set each working day by three market making members of The London Bullion Market Association (“London Fix”). Having valued the silver held by the Trust, the Trustee then subtracts all accrued fees (other than the fees to be computed by reference to the value of the Trust or its assets), expenses and other liabilities of the Trust from the value of the silver and other assets of the Trust. The result is the adjusted net asset value of the Trust, which is used to compute all fees (including the Sponsor’s fee), which are calculated from the value of the Trust’s assets. To determine the net asset value of the Trust, the Trustee subtracts from the adjusted net asset value of the Trust the amount of accrued fees computed from the value of the Trust’s assets. The Trustee also 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.

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.

Critical Accounting Policies

The financial statements and accompanying notes are prepared in accordance with accounting principles generally accepted 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. Below we describe the valuation of silver bullion, a critical accounting policy that we believe is important to understanding our results of operations and financial position. In addition, please refer to Note 2 to the financial statements for further discussion of our accounting policies.

Valuation of Silver Bullion

Silver bullion held by the Trust is recorded at the lower of cost or market. For purposes of this calculation, market values are based on the London Fix. Should the market value of the silver bullion held be lower than its average cost during the interim periods, an adjustment (“market value reserve”) to cost may be recorded by the Trust to reflect market value. At the end of the Trust’s fiscal year, management will make a determination on whether the reserve is recovered or whether the cost basis of silver should be written down. As indicated above, the London Fix is also used to value silver bullion held for purposes of calculating the net asset value of the Trust, which in turn is used for the calculation of the redemption value of outstanding Trust Shares.

There are other indicators of the value of silver bullion that are available that could be different than that chosen by the Trust. The London Fix 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 London Fix could result in materially different fair value pricing of the silver in the Trust, and as such, could result in different lower of cost or market adjustments or in different redemption value adjustments of the outstanding redeemable capital Shares.

Results of Operations

The Quarter Ended March 31, 2012

The Trust’s net asset value grew from $8,698,880,266 at December 31, 2011 to $10,091,773,011 at March 31, 2012, a 16.01% increase. The increase in the Trust’s net asset value resulted primarily from an increase in the London Fix price, which rose 15.08% from $28.18 at December 31, 2011 to $32.43 at March 31, 2012. Net asset value also increased due to an increase in outstanding Shares, which rose from 317,500,000 Shares at December 31, 2011 to 320,450,000 Shares at March 31, 2012, a consequence of 15,500,000 Shares (310 Baskets) being created and 12,550,000 Shares (251 Baskets) being redeemed during the quarter.

The 14.93% increase in the Trust’s net asset value per Share from $27.40 at December 31, 2011 to $31.49 at March 31, 2012 is directly related to the 15.08% increase in the London Fix price.

The Trust’s net asset value per Share increased slightly less than the price of silver on a percentage basis due to the Sponsor’s fees, which were $12,522,960 for the quarter, or 0.12% of the Trust’s average weighted assets of $10,088,115,977 during the quarter. The net asset value per Share of $36.17 on February 29, 2012 was the highest during the quarter, compared with a low during the quarter of $27.98 on January 3, 2012. The net asset value of the Trust is obtained by subtracting the Trust’s expenses and liabilities on any day from the value of the silver owned by the Trust on that day; the net asset value per Share is obtained by dividing the net asset value of the Trust on a given day by the number of Shares outstanding on that day.

Net income for the quarter ended March 31, 2012 was $96,722,951, resulting from a net gain of $3,292,738 on the sales of silver to pay expenses, a net gain of $105,953,173 on silver distributed for the redemption of Shares, offset by Sponsor’s fees of $12,522,960. Other than the Sponsor’s fees, the Trust had no expenses during the quarter.
