Gold Investment Overview

Gold is a physical asset that is accumulated, rather than consumed. This differentiates it from investment assets such as equities and fixed income instruments (which are claims on future cash flows), other commodities such as oil (which are consumed), and paper money (which can be more easily destroyed). These traits are among the reasons why gold may perform differently than other investments.

Gold ETFs

Exchange traded products, such as the iShares Gold Trust (IAU), represent an innovation for accessing the gold market. These investment vehicles typically offer the ability for investors to buy and sell their investment in gold through a brokerage account.

Physical Gold (i.e. Gold Coins)

Holding bullion, jewelry, coins and gold certificates provides pure access to gold. These forms of gold exposure, however, generally are not as liquid as holding a security (like a stock or futures contract) and may be impractical or costly to store buy and/or secure.

Derivatives (i.e. Futures, Options)

Derivatives and future contracts have predominately been limited to large institutional investors with the resources and experience to administer these positions. The cost of futures contracts can be significant due to the need to sell and reenter a position as it nears expiration.

Gold Mining Stocks

Prior to the introduction of exchange traded products, mutual funds presented the most viable option for individual investors or small institutions seeking to invest in gold because mutual funds provide convenient access to gold-linked investments at generally reasonable costs and low investment minimums. There are approximately 20 mutual funds encompassing over $29 billion in assets providing exposure to gold.* Investing in the equities of mining companies, however, provides imprecise exposure to gold given that mining companies may hedge their exposure to the price of gold. The five-year average correlation of precious metal mutual funds to the gold spot price is 0.75, while the five-year average correlation of precious metal mutual funds to the S&P 500 Index is 0.41**

Historical Price of Gold

Source: Bloomberg, as of 5/31/10. The gold spot settlement price is determined from the input of member firms; the spot price for gold is determined daily by the five member firms of the London Fix. Despite the differing pricing processes and the New York/London time difference, the prices of gold as measured by the two pricing methods have had a correlation of .9866 for the three-year period ending May 31, 2010.

iShares Gold Trust (“Trust”) has filed a registration statement (including a prospectus) with the SEC for the offering to which this communication relates. Before you invest, you should read the prospectus and other documents the Trust has filed with the SEC for more complete information about the issuer and this offering. You may get these documents for free by visiting www.iShares.com or EDGAR on the SEC website at www.sec.gov. Alternatively, the Trust will arrange to send you the prospectus if you request it by calling toll-free 1-800-474-2737. Investing involves risk, including possible loss of principal. The Trust is not 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 Trust are not subject to the same regulatory requirements as mutual funds. Because shares of the Trust are created to reflect the price of the gold held by the Trust, the market price of the shares will be as unpredictable as the price of gold has historically been. Additionally, shares of the Trust are bought and sold at market price (not NAV). Brokerage commissions will reduce returns. Shares of the Trust are created to reflect, at any given time, the market price of gold owned by the trust at that time less the trust’s expenses and liabilities. The price received upon the sale of the shares, which trade at market price, may be more or less than the value of the gold represented by them. 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 the risk factors relative to the Trust, carefully read the prospectus. Following an investment in shares of the Trust, several factors may have the effect of causing a decline in the prices of gold and a corresponding decline in the price of the shares. Among them: (i) Large sales by the official sector. A significant portion of the aggregate world gold holdings is owned by governments, central banks and related institutions. If one or more of these institutions decides to sell in amounts large enough to cause a decline in world gold prices, the price of the shares will be adversely affected. (ii) A significant increase in gold hedging activity by gold producers. Should there be an increase in the level of hedge activity of gold producing companies, it could cause a decline in world gold prices, adversely affecting the price of the shares. (iii) A significant change in the attitude of speculators and investors towards gold. Should the speculative community take a negative view towards gold, it could cause a decline in world gold prices, negatively impacting the price of the shares. The amount of gold represented by shares of the Trust will decrease over the life of the trust due to sales necessary to pay the sponsor’s fee and trust expenses. Without increase in the price of gold sufficient to compensate for that decrease, the price of the shares will also decline, and investors will lose money on their investment. The Trust will have limited duration. The liquidation of the trust may occur at a time when the disposition of the trust’s gold will result in losses to investors. Although market makers will generally take advantage of differences between the NAV and the trading price of 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 Trust will be adversely affected if gold owned by the trust is lost or damaged in circumstances in which the trust is not in a position to recover the corresponding loss. The 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, it might have been possible to avoid. Shares of the iShares Gold 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. BlackRock Asset Management International Inc. (“BAMII”) is the sponsor of the Trust. BlackRock Fund Distribution Company (“BFDC”), a subsidiary of BAMII, assists in the promotion of the Trust.

How does gold impact your portfolio?

Many investors today already diversify their portfolios across style, sectors and geographies. By including new asset classes that have low historical correlation to asset classes that are currently in their portfolio, investors can help further reduce portfolio volatility.

Gold has historically shown little to no correlation to major asset classes, including commodities. And while the price of gold is volatile, gold has historically displayed lower volatility than major asset classes over both long and short time periods. As a result, a small allocation to gold may help improve the risk/return trade-off of investment portfolios.

The following chart illustrates the historical effect of adding small amounts of gold to a diversified portfolio. As you can see, allocating 5% of the portfolio to gold improved the risk/return relationship of the portfolio primarily by reducing risk. You can see the effect of adding 10% or 20% as well.

Allocation to Gold:

Past performance does not guarantee future results. Standard Deviation: The Standard Deviation is the statistical measure of the degree to which an individual value in a probability distribution tends to vary from the mean of the distribution. It is widely applied in modern portfolio theory, where the past performance of securities is used to determine the range of possible future performance, and a probability is attached to each performance.

Gold is a potential “safe haven”

Gold has historically maintained its value during times of economic or political uncertainty. Investors have often retreated to gold when equity markets are struggling. Gold has exhibited positive performance during four of the five worst quarters of the S&P 500 Index’s performance since 1973. In addition, gold exhibited positive performance during seven of the ten worst quarters in the S&P 500 Index’s performance since 1973*.

*Sources: Bloomberg, BlackRock, as of 4/30/10. Gold: London PM Fix. Index and gold spot returns are for illustrative purposes only and do not reflect any fees or transaction costs. One cannot invest directly in an index or benchmark. Past performance does not guarantee future results.

Potential hedge against rising inflation

Rising inflation can be a result of two drivers, both of which may have an effect on the price of gold. Inflation can be the result of economic prosperity, in which case increased consumer wealth may drive an increased demand for luxury goods such as jewelry. In addition, inflation may be caused by relaxing monetary policy and increased money supply under times of economic distress. In this case, the price of gold may rise as investors seek to protect their wealth during economic uncertainty.

Potential hedge against devaluing dollar

The US dollar is widely viewed as the world’s main trading currency. Gold has historically been regarded as a good hedge when the dollar weakens relative to other currencies.

The chart below shows the historical relationship between the price of gold and the US Dollar Index. The US Dollar Index is a measure of the value of the US dollar relative to a basket of foreign currencies. When the US Dollar Index is positive, it indicates a strengthening US dollar. As the chart below shows, a strengthening US dollar has historically been negatively correlated with gold.
