SUPPLEMENT DATED NOVEMBER 6, 2012

TO THE STATEMENT OF ADDITIONAL INFORMATION (“SAI”) DATED MARCH 1, 2012, AS SUPPLEMENTED

This Supplement updates certain information contained in the above-dated SAI for Global X Funds.

Effective immediately, the following paragraphs replaces the section “Equity Swaps, Total Rate of Return Swaps and Currency Swaps” on pages 6-7 of the SAI:

EQUITY SWAPS, TOTAL RATE OF RETURN SWAPS AND CURRENCY SWAPS. The Fund may invest up to 20% of its total assets in swap contracts.

A swap is an agreement involving the exchange by a Fund with another party of their respective commitments to pay or receive payments at specified dates based upon or calculated by reference to changes in specified prices or rates (e.g., interest rates in the case of interest rate swaps) based on a specified amount (the “notional” amount). Some swaps currently are, and more in the future will be, centrally cleared. Examples of swap agreements include, but are not limited to, equity, index or other total return swaps and foreign currency swaps.

The Fund may enter into equity swap contracts to invest in a market without owning or taking physical custody of securities in circumstances in which direct investment is restricted for legal reasons or is otherwise impracticable. These instruments provide a great deal of flexibility. For example, a counterparty may agree to pay the Fund the amount, if any, by which the notional amount of the equity swap contract would have increased in value had it been invested in particular stocks (or an index of stocks), plus the dividends that would have been received on those stocks. In these cases, the Fund may agree to pay to the counterparty the amount, if any, by which that notional amount would have decreased in value had it been invested in the stocks. Therefore, the return to the Fund on any equity swap contract should be the gain or loss on the notional amount plus dividends on the stocks less the interest paid by the Fund on the notional amount. In other cases, the counterparty and the Fund may each agree to pay the other the difference between the relative investment performances that would have been achieved if the notional amount of the equity swap contract had been invested in different stocks (or indices of stocks).

Total rate of return swaps are contracts that obligate a party to pay or receive interest in exchange for the payment by the other party of the total return generated by a security, a basket of securities, an index or an index component. The Fund also may enter into currency swaps, which involve the exchange of the rights of the Fund and another party to make or receive payments in specific currencies. Currency swaps involve the exchange of rights of the Fund and another party to make or receive payments in specific currencies.

Some swaps transactions are entered into on a net basis, i.e., the two payment streams are netted out, with the Fund receiving or paying, as the case may be, only the net amount of the two payments. The Fund will enter into equity swaps only on a net basis. Payments may be made at the conclusion of an equity swap contract or periodically during its term. Equity swaps do not involve the delivery of securities or other underlying assets. Accordingly, the risk of loss with respect to equity swaps is limited to the net amount of payments that such Fund is contractually obligated to make. If the other party to an equity swap, or any other swap entered into on a net basis, defaults, the Fund’s risk of loss consists of the net amount of payments that such Fund is contractually entitled to receive, if any. In contrast, other swaps transactions may involve the payment of the gross amount owed. For example, currency swaps usually involve the delivery of the entire principal amount of one designated currency in exchange for the other designated currency. Therefore, the entire principal value of a currency swap is subject to the risk that the other party to the swap will default on its contractual delivery obligations. To the extent that the amount payable by the Fund under a swap is covered by segregated cash or liquid assets, the Fund and the Adviser believe that transactions do not constitute senior securities under the 1940 Act and, accordingly, will not treat them as being subject to the Fund’s borrowing restrictions.

Swaps that are centrally-cleared are subject to the creditworthiness of the clearing organizations involved in the transaction. For example, an investor could lose margin payments it has deposited with the clearing organization as well as the net amount of gains not yet paid by the clearing organization if it breaches its agreement with the investor or becomes insolvent or goes into bankruptcy. In the event of bankruptcy of the clearing organization, the investor may be entitled to the net amount of gains the investor is entitled to receive plus the return of margin owed to it only in proportion to the amount received by the clearing organization’s other customers, potentially resulting in losses to the investor.

To the extent a swap is not centrally cleared, the use of swaps also involves the risk that a loss may be sustained as a result of the insolvency or bankruptcy of the counterparty or the failure of the counterparty to make required payments or otherwise comply with the terms of the agreement.

The Fund will not enter into any swap transactions unless the unsecured commercial paper, senior debt or claims-paying ability of the other party is rated either A, or A-1 or better by S&P, or Fitch Ratings (“Fitch”); or A or Prime-1 or better by Moody’s, or has received a comparable rating from another organization that is recognized as a nationally recognized statistical rating organization (“NRSRO”) or, if unrated by such rating organization, is determined to be of comparable quality by the Adviser. If a counterparty’s creditworthiness declines, the value of the swap might decline, potentially resulting in losses to a Fund. Changing conditions in a particular market area, whether or not directly related to the referenced assets that underlie the swap agreement, may have an adverse impact on the creditworthiness of the counterparty. For example, the counterparty may have experienced losses as a result of its exposure to a sector of the market that adversely affect its creditworthiness. If there is a default by the other party to such a transaction, the Fund will have contractual remedies pursuant to the agreements related to the transaction. Such contractual remedies, however, may be subject to bankruptcy and insolvency laws that may affect such Fund’s rights as a creditor (e.g . , the Fund may not receive the net amount of payments that it contractually is entitled to receive). The swap market has grown substantially in recent years with a large number of banks and investment banking firms acting both as principals and as agents utilizing standardized swap documentation. As a result, the swap market has become relatively liquid in comparison with markets for other similar instruments which are traded in the interbank market.

The use of equity, total rate of return and currency swaps is a highly specialized activity which involves investment techniques and risks different from those associated with ordinary portfolio securities transactions.

In connection with the Fund’s position in a swaps contract, the Fund will segregate liquid assets or will otherwise cover its position in accordance with applicable SEC requirements.

Effective immediately, the following paragraphs replace the section “Futures Contracts and Related Options” on page 11 of the SAI:

FUTURES CONTRACTS AND OPTIONS ON FUTURES CONTRACTS. To the extent consistent with its investment policies, the Fund may invest up to 20% of its total assets (minus any percent of Fund assets invested in other derivatives) in U.S. or foreign futures contracts and may purchase and sell call and put options on futures contracts. These futures contracts and options will be used to simulate full investment in the respective Underlying Index, to facilitate trading or to reduce transaction costs. The Fund will only enter into futures contracts and options on futures contracts that are traded on a U.S. or foreign exchange. The Fund will not use futures or options for speculative purposes. In connection with the Fund’s position in a futures contract or related option, the Fund will segregate liquid assets or will otherwise cover its position in accordance with applicable SEC requirements.

Futures Contracts . Each Fund may enter into certain equity, index and currency futures transactions, as well as other futures transactions that become available in the markets. By using such futures contracts, the Funds may obtain exposure to certain equities, indexes and currencies without actually investing in such instruments. Index futures may be based on broad indices, such as the S&P 500 Index, or narrower indices. A futures contract on foreign currency creates a binding obligation on one party to deliver, and a corresponding obligation on another party to accept delivery of, a stated quantity of foreign currency for an amount fixed in U.S. dollars. Foreign currency futures may be used by a Fund to help the Fund track the price and yield performance of its Underlying Index.

Some futures contracts are traded on organized exchanges regulated by the SEC or Commodity Futures Trading Commission (“CFTC”), and transactions on them are cleared through a clearing corporation, which guarantees the performance of the parties to the contract. If regulated by the CFTC, such exchanges may be designated contract markets or swap execution facilities.

The Fund may also engage in transactions in foreign stock index futures, which may be traded on foreign exchanges. Participation in foreign futures and foreign options transactions involves the execution and clearing of trades on or subject to the rules of a foreign board of trade. Neither the National Futures Association (“NFA”) nor any domestic exchange regulates activities of any such organization, even if it is formally linked to a domestic market. Moreover, foreign laws and regulations and transactions executed under such laws and regulation may not be afforded certain of the protective measures provided by domestically. In addition, the price of foreign futures or foreign options contract may be affected by any variance in the foreign exchange rate between the time an order is placed and the time it is liquidated, offset or exercised.

Unlike purchases or sales of portfolio securities, no price is paid or received by a Fund upon the purchase or sale of a futures contract. Initially, the Fund will be required to deposit with the broker or in a segregated account with a custodian or sub-custodian an amount of liquid assets, known as initial margin, based on the value of the contract. The nature of initial margin in futures transactions is different from that of margin in security transactions in that futures contract margin does not involve the borrowing of funds by the customer to finance the transactions. Rather, the initial margin is in the nature of a performance bond or good faith deposit on the contract, which is returned to the Fund upon termination of the futures contract assuming all contractual obligations have been satisfied. Subsequent payments, called variation margin, to and from the broker, will be made on a daily basis as the price of the underlying instruments fluctuates making the long and short positions in the futures contract more or less valuable, a process known as “marking-to-market.” For example, when a Fund has purchased a futures contract and the price of the contract has risen in response to a rise in the underlying instruments, that position will have increased in value and the Fund will be entitled to receive from the broker a variation margin payment equal to that increase in value. Conversely, where a Fund has purchased a futures contract and the price of the future contract has declined in response to a decrease in the underlying instruments, the position would be less valuable and the Fund would be required to make a variation margin payment to the broker. Prior to expiration of the futures contract, the Adviser may elect to close the position by taking an opposite position, subject to the availability of a secondary market, which will operate to terminate the Fund’s position in the futures contract. A final determination of variation margin is then made, additional cash is required to be paid by or released to the Fund, and the Fund realizes a loss or gain.

There are several risks in connection with the use of futures by a Fund. One risk arises because of the imperfect correlation between movements in the price of the futures and movements in the price of the instruments which are the subject of the hedge. The price of the future may move more than or less than the price of the instruments being hedged. If the price of the futures moves less than the price of the instruments which are the subject of the hedge, the hedge will not be fully effective but, if the price of the instruments being hedged has moved in an unfavorable direction, the Fund would be in a better position than if it had not hedged at all. If the price of the instruments being hedged has moved in a favorable direction, this advantage will be partially offset by the loss on the futures. If the price of the futures moves more than the price of the hedged instruments, the Fund involved will experience either a loss or gain on the futures which will not be completely offset by movements in the price of the instruments that are the subject of the hedge. To compensate for the imperfect correlation of movements in the price of instruments being hedged and movements in the price of futures contracts, a Fund may buy or sell futures contracts in a greater dollar amount than the dollar amount of instruments being hedged if the volatility over a particular time period of the prices of such instruments has been greater than the volatility over such time period of the futures, or if otherwise deemed to be appropriate by the Adviser. Conversely, a Fund may buy or sell fewer futures contracts if the volatility over a particular time period of the prices of the instruments being hedged is less than the volatility over such time period of the futures contract being used, or if otherwise deemed to be appropriate by the Adviser.

In addition to the possibility that there may be an imperfect correlation, or no correlation at all, between movements in the futures and the instruments being hedged, the price of futures may not correlate perfectly with movement in the cash market due to certain market distortions. Rather than meeting additional margin deposit requirements, investors may close futures contracts through off-setting transactions which could distort the normal relationship between the cash and futures markets. Second, with respect to financial futures contracts, the liquidity of the futures market depends on participants entering into off-setting transactions rather than making or taking delivery. To the extent participants decide to make or take delivery, liquidity in the futures market could be reduced thus producing distortions. Third, from the point of view of speculators, the deposit requirements in the futures market are less onerous than margin requirements in the securities market. Therefore, increased participation by speculators in the futures market may also cause temporary price distortions. Due to the possibility of price distortion in the futures market, and because of the imperfect correlation between the movements in the cash market and movements in the price of futures, a correct forecast of general market trends or interest rate movements by the Adviser may still not result in a successful hedging transaction over a short time frame.

In general, positions in futures may be closed out only on an exchange, board of trade or other trading facility that provides a secondary market for such futures. Although each Fund intends to purchase or sell futures only on trading facilities where there appear to be active secondary markets, there is no assurance that a liquid secondary market on any trading facility will exist for any particular contract or at any particular time. In such an event, it may not be possible to close a futures contract position, and in the event of adverse price movements, a Fund would continue to be required to make daily cash payments of variation margin. However, in the event futures contracts have been used to hedge portfolio securities, such securities may not be sold until the futures contract can be terminated. In such circumstances, an increase in the price of the securities, if any, may partially or completely offset losses on the futures contract. However, as described above, there is no guarantee that the price of the securities will in fact correlate with the price movements in the futures contract and thus provide an offset on a futures contract.

Further, it should be noted that the liquidity of a secondary market in a futures contract may be adversely affected by “daily price fluctuation limits” established by commodity exchanges which limit the amount of fluctuation in a futures contract price during a single trading day. Once the daily limit has been reached in the contract, no trades may be entered into at a price beyond the limit, thus preventing the liquidation of open futures positions. The trading of futures contracts is also subject to the risk of trading halts, suspensions, exchange or clearing house equipment failures, government intervention, insolvency of a brokerage firm or clearing house or other disruptions of normal trading activity, which could at times make it difficult or impossible to liquidate existing positions or to recover excess variation margin payments.

Successful use of futures by a Fund is subject to the Adviser’s ability to predict correctly movements in the direction of the market. In addition, in such situations, if a Fund has insufficient cash, it may have to sell securities to meet daily variation margin requirements. Such sales of securities may be, but will not necessarily be, at increased prices which reflect the rising market. A Fund may have to sell securities at a time when it may be disadvantageous to do so.

Options on Futures Contracts . A Fund may purchase and write options on the futures contracts described above. A futures option gives the holder, in return for the premium paid, the right to receive and execute a long futures contract (if the option is a call) or a short futures contract (if the option is a put) at a specified price at any time during the period of the option. Like the buyer or seller of a futures contract, the holder, or writer, of an option has the right to terminate its position prior to the scheduled expiration of the option by selling, or purchasing an option of the same series, at which time the person entering into the closing transaction will realize a gain or loss. Each Fund will be required to deposit initial margin and variation margin with respect to put and call options on futures contracts written by it pursuant to brokers’ requirements similar to those described above. Net option premiums received will be included as initial margin deposits.

Investments in futures options involve some of the same considerations that are involved in connection with investments in futures contracts (for example, the existence of a liquid secondary market). In addition, the purchase or sale of an option also entails the risk that changes in the value of the underlying futures contract will not correspond to changes in the value of the option purchased. Depending on the pricing of the option compared to either the futures contract upon which it is based, or upon the price of the securities being hedged, an option may or may not be less risky than ownership of the futures contract or such securities. In general, the market prices of options can be expected to be more volatile than the market prices on the underlying futures contract. Compared to the purchase or sale of futures contracts, however, the purchase of call or put options on futures contracts may frequently involve less potential risk to a Fund because the maximum amount at risk is the premium paid for the options (plus transaction costs). The writing of an option on a futures contract involves risks similar to those risks relating to the purchase or sale of futures contracts.

Effective immediately, the following paragraph should be inserted before the section “Government Intervention in Financial Markets” on page 11 of the SAI:

CFTC REGULATION. In February 2012, the CFTC announced substantial amendments to the exclusions, and to the conditions for reliance on the exclusions, from registration as a commodity pool operator. Under these amendments, a Fund may only use a de minimis amount of commodity interests (such as futures contracts, options on futures contracts and swaps) other than for bona fide hedging purposes (as defined by the CFTC). A de minimis amount is defined as amount such that the aggregate initial margin and premiums required to establish these positions (after taking into account unrealized profits and unrealized losses on any such positions and excluding the amount by which options that are “in-the-money” at the time of purchase) may not exceed 5% of the Fund’s net asset value or, alternatively, the aggregate net notional value of those positions, determined at the time the most recent position was established, may not exceed 100% of the Fund’s net asset value (after taking into account unrealized profits and unrealized losses on any such positions). The CFTC amendments became effective on April 24, 2012, but the compliance date is December 31, 2012. Therefore, pending judicial challenge, as of January 1, 2013, the CFTC amendments will impose limitations on the Funds’ trading of commodity interests. Because, however, each of the Funds engages only in a de minimis amount of such transactions, the Funds expect to continue to claim an exclusion from registration as a commodity pool operator under the Commodity Exchange Act, and the Adviser expects to continue to claim an exclusion as a commodity trading advisor with respect to the Funds. Therefore, none of the Funds or the Adviser expect to be subject to the registration and regulatory requirements of the Commodity Exchange Act.

Effective immediately, the following paragraph and chart replaces the paragraph under the “Brokerage Transactions” section on page 42 of the SAI:

The policy of the Trust regarding purchases and sales of securities is that primary consideration will be given to obtaining the most favorable prices and efficient executions of transactions. Consistent with this policy, when securities transactions are effected on a stock exchange, the Trust’s policy is to pay commissions that are considered fair and reasonable without necessarily determining that the lowest possible commissions are paid in all circumstances. In seeking to determine the reasonableness of brokerage commissions paid in any transaction, the Adviser relies upon its experience and knowledge regarding commissions generally charged by various brokers and in various jurisdictions. The Adviser effects transactions for the Fund with those brokers and dealers that the Adviser believes provide the most favorable prices and are capable of providing the most efficient and best execution of trades. The primary consideration of the Adviser is to seek prompt execution of orders at the most favorable net price. The sale of Shares by a broker-dealer is not a factor in the selection of broker-dealers. The Adviser and its affiliates do not currently participate in any soft dollar transactions, although the Adviser relies on Section 28(e) of the 1934 Act in effecting or executing transactions for the Fund. Accordingly, in selecting broker-dealers to execute a particular transaction, the Adviser may consider the brokerage and research services (as those terms are defined in Section 28(e) of the 1934 Act) provided to the Fund and/or other accounts over which the Adviser or its affiliates exercise investment discretion. The Adviser may cause the Fund to pay a broker-dealer that furnishes brokerage and research services a higher commission than that which might be charged by another broker-dealer for effecting the same transaction, provided that the Adviser determines in good faith that such commission is reasonable in relation the value of the brokerage and research services provided by such broker-dealer, viewed in terms of either the particular transaction or the overall responsibilities of the Adviser to the Fund. Such brokerage and research services might consist of reports and statistics on specific companies or industries or broad overviews of the securities markets and the economy. Shareholders of the Fund should understand that the services provided by such brokers may be useful to the Adviser in connection with its services to other clients.

The Adviser assumes general supervision over placing orders on behalf of the Fund for the purchase or sale of portfolio securities. If purchases or sales of portfolio securities by the Fund are considered at or about the same time, transactions in such securities are allocated among the Fund in a manner deemed equitable to the Fund by the Adviser. Bundling or bunching transactions for the Fund is intended to result in better prices for portfolio securities and lower brokerage commissions, which should be beneficial to the Fund.

The aggregate brokerage commissions paid by each Fund during the fiscal period ended October 31, 2009, 2010 and 2011 are set forth in the chart below.

Effective immediately, “Appendix B” on pages B1-B4 of the SAI is deleted.
