GOLD FOR PORTFOLIOS GLD® SPDR® Gold Shares GLDW SPDR® Long Dollar Gold Trust GLDM SPDR® Gold MiniSharesâ„

WHY CONSIDER INVESTING IN GOLD?Gold is both an investment and a consumer good. Global economic growth, income growth, monetary policy and market volatility drive demand. A strategic allocation to this unique asset class may help an investor to pursue the following potential benefits of gold: Long-term Returns Since 1971, when President Nixon removed the US dollar from the Gold Standard, the price of gold has increased from $43.28/oz. to $1323.85/oz. at the end of March 2018, or a compounded annual growth rate of 7.79 percent per year.1 Gold’s prices are influenced by a diverse set of global drivers in pro-cyclical and counter-cyclical markets. Greater Diversification Gold’s historically low or negative correlation to other asset classes means the potential for greater diversification that could potentially lower portfolio volatility, enhance overall risk-adjusted returns and preserve purchasing power. Improved Risk-Adjusted Returns Because gold has historically tended to rise during stock market pullbacks, a strategic allocation to gold in a multi-asset class portfolio may help temper the impact of market volatility and reduce portfolio drawdown. Deep Liquidity The average daily turnover of gold is over $250 billion, equivalent to $62 trillion per year. That makes the gold market larger than that of many stocks and bonds.2 An investment in any combination of GLD, GLDW and GLDM entails a risk of loss and the diversification offered by the Funds does not ensure a profit or guarantee against loss. 1 Bloomberg Finance L.P., State Street Global Advisors, August 13, 1971– March 31, 2018. 2 Source: A study carried out by London Bullion Market Association and overseen by the Bank of England and the Financial Conduct Authority; GFMS-Thomson Reuters, date as of December 31, 2017. 7.79% Compounded annual growth rate for LBMA Gold Price PM since 19711Gold’s Historically Relatively Low or Negative Correlation with Equity and Bond Markets Since 2000 n Major n Major Bond Markets Equity Markets -0.08 -0.09 0.12 0.01 0.29 0.27 Japanese Global US European US Aggregate Bonds US Corporate -1.0 -0.8 -0.6 -0.4 -0.2 0.0 0.2 0.4 0.6 0.8 1.0 Source: Bloomberg Finance L.P., State Street Global Advisors, data from January 1, 2000 to March 31, 2018.

Today, as the largest gold-backed ETF in the world in terms of AUM,3 GLD is designed to offer all investors easy and relatively highly liquid access to the gold market. GLDW Gold for a Strong Dollar Environment Launched January 31, 2017, the SPDR® Long Dollar Gold Trust (GLDW) is designed to offer investors the potential benefits of using gold as a strategic portfolio diversifier while countering the historically negative correlation between a strengthening U.S. dollar and gold prices.

ssga.com | spdrs.com Important Risk Information Investing involves risk, and you could lose money on an investment in each of SPDR® Gold Shares Trust (“GLD®”), SPDR® Gold MiniSharesSM Trust (“GLDMSM”), a series of the World Gold Trust, and SPDR® Long Dollar Gold Trust (“GLDWSM”), a series of the World Gold Trust (together, the “Funds”). ETFs trade like stocks, are subject to investment risk, fluctuate in market value and may trade at prices above or below the ETFs’ net asset value. Brokerage commissions and ETF expenses will reduce returns. Commodities and commodity-index linked securities may be affected by changes in overall market movements, changes in interest rates, and other factors such as weather, disease, embargoes, or political and regulatory developments, as well as trading activity of speculators and arbitrageurs in the underlying commodities. GLDW is subject to regulation under the Commodity Exchange Act of 1936 (the “CEA”). U.S. regulation of swap agreements is rapidly changing and is subject to further regulatory developments which could be adverse to GLDW. GLDW’s swap agreements will be subject to counterparty risk and liquidity risk. Currency exchange rates between the U.S. dollar and non-U.S. currencies may fluctuate significantly over short periods of time and may cause the value of GLDW’s investments to decline. GLDW is a passive investment vehicle that is designed to track the Index. GLDW’s performance may deviate from changes in the levels of its Index (i.e., create “tracking error” between GLDW and the Index) for a number of reasons, such as the fees and expenses of GLDW, which are not accounted for by the Index. Frequent trading of ETFs could significantly increase commissions and other costs such that they may offset any savings from low fees or costs. Diversification does not ensure a profit or guarantee against loss. Investing in commodities entails significant risk and is not appropriate for all investors. Important Information Relating to SPDR® Gold Trust (“GLD®”), SPDR® Gold MiniSharesSM Trust (“GLDMSM”) and SPDR® Long Dollar Gold Trust (“GLDWSM”): The SPDR Gold Trust (“GLD”) has filed a registration statement (including a prospectus) with the Securities and Exchange Commission (“SEC”) for GLD. The World Gold Trust has filed a registration statement (including a prospectus) with the SEC for each of GLDM and GLDW. The World Gold Trust has also filed the prospectus for GLDW with the National Futures Association. Before you invest, you should read the prospectus in the registration statement and other documents each Fund has filed with the SEC for more complete information about each Fund and these offerings. Please see each Fund’s prospectus for a detailed discussion of the risks of investing in each Fund’s shares. The GLD prospectus is available by clicking here, the GLDM prospectus is available by clicking here, and the GLDW prospectus is available by clicking here. You may get these documents for free by visiting EDGAR on the SEC website at sec.gov or by visiting spdrgoldshares.com. Alternatively, the Funds or any authorized participant will arrange to send you the prospectus if you request it by calling 866.320.4053. None of the Funds is an investment company registered under the Investment Company Act of 1940 (the “1940 Act”). As a result, shareholders of each Fund do not have the protections associated with ownership of shares in an investment company registered under the 1940 Act. GLD and GLDM are not subject to regulation under the CEA. As a result, shareholders of each of GLD and GLDM do not have the protections afforded by the CEA. Shares of each Fund trade like stocks, are subject to investment risk and will fluctuate in market value. The values of GLD shares and GLDM shares relate directly to the value of the gold held by each Fund (less its expenses), respectively. Fluctuations in the price of gold could materially and adversely affect an investment in the shares. 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. GLDW shares trade like stocks, are subject to investment risk and will fluctuate in market value. The value of GLDW shares relates directly to the value of the gold held by GLDW (less its expenses) and the value of a basket (“FX Basket”) comprising the euro, Japanese yen, British pound sterling, Canadian dollar, Swedish krona and Swiss franc (“Reference Currencies”) against the U.S. dollar. A decline in the price of gold and/or an increase in the value of the Reference Currencies comprising the FX basket against the U.S. dollar could materially and adversely affect an investment in the shares. 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 and the price of each Reference Currency against the U.S. dollar represented by them. None of the Funds generate any income, and as each Fund regularly sells gold to pay for its ongoing expenses, the amount of gold represented by each Fund share will decline over time to that extent.
