Investing involves risk, including possible loss of principal. Neither the iShares Gold Trust nor the iShares Silver Trust (collectively, the “Trusts”) is an investment company registered under the Investment Company Act of 1940 or a commodity pool for purposes of the Commodity Exchange Act. Shares of the Trusts are not subject to the same regulatory requirements as mutual funds. Because shares of the Trusts are expected to reflect the price of the silver and gold held by the Silver Trust and the Gold Trust, respectively, the market price of the shares will be as unpredictable as the prices of silver and gold have historically been. Additionally, shares of the Trusts are bought and sold at market price (not NAV). Brokerage commissions will reduce returns.

Shares of the Trusts 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.

BlackRock Asset Management International Inc. (“BAMII”) is the sponsor of the Trusts. BlackRock Fund Distribution Company (“BFDC”), a subsidiary of BAMII, assists in the promotion of the Trusts.
