iShares Silver Trust (SLV): Overview - iShares by calling toll-free 1-800-474-2737. London Silver Fix Price returns are for illustrative purposes only and do not represent actual iShares Silver Trust performance. London Silver Fix Price returns do not reflect any fees, transaction costs or expenses. London Fix is the price per ounce of silver set by three market making members of the London Bullion Market Association at approximately 12:00 noon, London time, on each working day. The sponsor of the trust is iShares Delaware Trust Sponsor LLC (the “Sponsor”). BlackRock Investments, LLC (“BRIL”), assists in the promotion of the Trust. The Sponsor and BRIL are affiliates of BlackRock, Inc. Investing involves risk, including possible loss of principal. Because shares of the Silver Trust are intended to reflect the price of the silver held by the Silver Trust, the market price of the shares is subject to fluctuations similar to those affecting silver prices. Additionally, shares of the Silver Trust are bought and sold at market price, not at net asset value (“NAV”). Brokerage commissions will reduce returns. Shares of the Silver Trust are intended to reflect, at any given time, the market price of silver owned by the Trust at that time less the Trust’s expenses and liabilities. The price received upon the sale of shares of the Silver Trust, which trade at market price, may be more or less than the value of the silver represented by such shares. If an investor sells the shares at a time when no active market for them exists, such lack of an active market will most likely adversely affect the price received for the shares. For a more complete discussion of risk factors relative to the Silver Trust, carefully read the prospectus. Following an investment in the iShares Silver Trust, several factors may have the effect of causing a decline in the prices of silver and a corresponding decline in the price of the shares. Among them: (i) A change in economic conditions, such as a recession, can adversely affect the price of silver. Silver is used in a wide range of industrial applications, and an economic downturn could have a negative impact on its demand and, consequently, its price and the price of the shares. (ii) A significant change in the attitude of speculators and investors towards silver. Should the speculative community take a negative view towards silver, a decline in world silver prices could occur, negatively impacting the price of the shares. (iii) A significant increase in silver price hedging activity by silver producers. Traditionally, silver producers have not hedged to the same extent as other producers of precious metals (gold, for example) do. Should there be an increase in the level of hedge activity of silver producing companies, it could cause a decline in world silver prices, adversely affecting the price of the shares. Silver Spot Prices provided by The Bullion Desk. No warranty is given for the accuracy of these prices and no liability is accepted for reliance thereon. Prices are provided on a reasonable efforts basis and delays may occur both because of the delay in third parties communicating the information to the site and because of delays inherent in posting information over the internet. Prices shown are indicative only and do not represent actionable quotations on prices of actual trades. Although shares of the iShares Silver Trust may be bought or sold on the secondary market through any brokerage account, shares are not redeemable except in large aggregated units called “Baskets”. Only registered broker-dealers that become authorized participants by entering into a contract with the sponsor and the trustee of the Trust may purchase or redeem Baskets. The amount of silver represented by shares of the Silver Trust will decrease over the life of the Silver Trust due to sales of silver necessary to pay the sponsor’s fee and Silver Trust expenses. Without increases in the price of silver sufficient to compensate for that decrease, the price of the shares will also decline, and investors will lose money on their investment in the shares. The Silver Trust will have limited duration. The liquidation of the trust may occur at a time when the disposition of the trust’s silver will result in losses to investors. Although market makers will generally take advantage of differences between the NAV and the trading price of Silver Trust shares through arbitrage opportunities, there is no guarantee that they will do so. There is no guarantee an active trading market will develop for the shares, which may result in losses on your investment at the time of disposition of your shares. The value of the shares of the Silver Trust will be adversely affected if silver owned by the trust is lost or damaged in circumstances in which the Silver Trust is not in a position to recover the corresponding loss. The Silver Trust is a passive investment vehicle. This means that the value of your shares may be adversely affected by trust losses that, if the trust had been actively managed, might have been avoidable. Shares of the iShares Silver Trust are not deposits or other obligations of or guaranteed by BlackRock, Inc., and its affiliates, and are not insured by the Federal Deposit Insurance Corporation or any other governmental agency. When comparing commodities and the Silver Trust, it should be remembered that the sponsor’s fee associated with the Trust is not borne by investors in individual commodities. Buying and selling shares of the Silver Trust will result in brokerage commissions. Because the expenses involved in an investment in physical silver will be dispersed among all holders of shares of the Silver Trust, an investment in the Silver Trust may represent a cost-efficient alternative to investments in silver for investors not otherwise able to participate directly in the market for physical silver. Certain sectors and markets perform exceptionally well based on current market conditions and the iShares Silver Trust can benefit from that performance. Achieving such exceptional returns involves the risk of volatility and investors should not expect that such results will be repeated. Options involve risk and are not suitable for all investors.

Net Asset Value (NAV) is determined as specified in the prospectus: the iShares Silver Trust’s silver and other assets are valued on the basis of each day’s announced London Fix, the price for an ounce of silver set by three market making members of the London Bullion Market Association, minus all accrued fees, expenses and liabilities. The Premium/Discount table presents information about the difference between the daily market price for shares of the iShares Silver Trust and the iShares Silver Trust’s net asset value. The market price is determined using the midpoint between the highest bid and the lowest offer on the listing exchange, as of the time that the iShares Silver Trust’s NAV is calculated (usually 4:00 p.m. eastern time). The table above shows the premium or discount expressed as a percentage of NAV. Although market makers will generally take advantage of differences between the NAV and the trading price of iShares Trust shares through arbitrage opportunities, there is no guarantee that they will do so. Why is there a difference between NAV and Closing Price? A major reason for the difference is that Timing Discrepancies can exist between the NAV and Closing Price (last trade) reported above. Information is constantly flowing to and among investors, corporations, and financial institutions that affects their outlook on the financial markets and the value of securities. This process, known as Price Discovery, is why market prices change and evolve throughout the trading day. It is important to note that even when markets are closed, the price discovery process continues 24 hours a day, 7 days a week, 365 days a year. Possible Timing Discrepancies: Close of Trading Times: The NAV of the iShares Silver Trust normally is calculated using prices as of 4:00 p.m. ET. Shares of the iShares Silver Trust (“iShares”) normally trade on the NYSE Arca Exchange until 4:15 p.m. ET. Price discovery between 4:00 p.m. and 4:15 p.m. ET may result in a difference between the NAV and the Closing Price of the iShares Silver Trust. Time of Last Trade: Trading generally takes place throughout the normal trading hours for the iShares Silver Trust on the listing exchange. At times, many trades are placed in rapid succession. At other times, little or no trading activity is taking place. It is important to note that the date/time of the last trade (which is recorded as the Closing Price) may not take place at exactly 4:00 p.m. ET whe n the iShares Silver Trust normally calculates NAV. The date/time of the last trade sometimes may occur before 4:00 p.m. ET or up until 4:15 p.m. ET as discussed above. Thus, ongoing price discovery may result in a deviation between the price recorded as the Closing Price and the NAV of the iShares Silver Trust shares at 4:00 p.m. ET. © 2000-2012 BlackRock.
