E6-6077. Self-Regulatory Organizations; New York Stock Exchange LLC; Notice of Filing of Proposed Rule Change and Amendment No. 1 Thereto To List and Trade Shares of the iShares GSCI Commodity Indexed Trust Under New Rules 1300B and 1301B, et seq.

April 17, 2006.

Pursuant to section 19(b)(1) of the Securities Exchange Act of 1934 (“Act”),^[1] and Rule 19b-4 thereunder,^[2] notice is hereby given that on March 7, 2006, the New York Stock Exchange LLC (“NYSE” or “Exchange”) filed with the Securities and Exchange Commission (“Commission”) the proposed rule change as described in Items I, II, and III below, which items have been prepared by the NYSE. On March 24, 2006, the Exchange filed Amendment No. 1 to the proposed rule change.^[3] The Commission is publishing this notice to solicit comments on the proposed rule change, as amended, from interested persons.

I. Self-Regulatory Organization's Statement of the Terms of Substance of the Proposed Rule Change

The NYSE proposes to list and trade under new NYSE Rules 1300B, et seq. shares (“Commodity Trust Shares” or “Shares”) of the iShares® GSCI® Commodity—Indexed Trust (“Trust”), which will issue units of beneficial interest representing fractional undivided beneficial interests in the net assets of the Trust. NYSE Rules 1300B and 1301B are set forth below, with new text underlined:

Rule 1300B

Commodity Trust Shares

(a) The provisions of this Rule 1300B series apply only to Commodity Trust Shares. The term “Commodity Trust Shares” as used in this Rule and in Rule 1301B means a security that (a) is issued by a trust (“Trust”) which (i) is a commodity pool that is managed by a commodity pool operator registered as such with the Commodity Futures Trading Commission, and (ii) which holds positions in futures contracts on a specified commodity index, or interests in a commodity pool which, in turn, holds such positions; (b) when aggregated in some specified minimum number may be surrendered to the Trust by the beneficial owner to receive positions in futures contracts on a specified index and cash or short term securities. The term “futures contract” is commonly known as a “contract of sale of a commodity for future delivery” set forth in section 2(a) of the Commodity Exchange Act. While Commodity Trust Shares are not technically Investment Company Units and thus are not covered by Rule 1100, all other rules that reference “Investment Company Units,” as defined and used in Para. 703.16 of the Listed Company Manual, including, but not limited to Rules 13, 36.30, 98, 104, 460.10, 1002, and 1005 shall also apply to Commodity Trust Shares. When these rules reference Investment Company Units, the word “index” (or derivative or similar words) will be deemed to be the applicable commodity index and the word “security” (or derivative or similar words) will be deemed to be “Commodity Trust Shares”.

(b) As is the case with Investment Company Units, paragraph (m) of the Guidelines to Rule 105 shall also apply to Commodity Trust Shares. Specifically, Rule 105(m) shall be deemed to prohibit an equity specialist, his member organization, other member, allied member or approved person in such member organization or officer or employee thereof from acting as a market maker or functioning in any capacity involving market-making responsibilities in the physical commodities included in, or options, futures or options on futures on, the index underlying an issue of Commodity Trust Shares, or any other derivatives based on such index or based on any commodity included in such index. However, an approved person of an equity specialist entitled to an exemption from Rule 105(m) under Rule 98 may act in a market making capacity, other than as a specialist in the same issue of Commodity Trust Shares in another market center, in physical commodities included in, or options, futures or options on futures on, the index underlying an issue of Commodity Trust Shares, or any other derivatives based on such index or based on any commodity included in such index.

(c) Except to the extent that specific provisions in this Rule govern, or unless the context otherwise requires, the provisions of all Exchange Rules and policies shall be applicable to the trading of Commodity Trust Shares on the Exchange. Pursuant to Exchange Rule 3 (“Security”), Commodity Trust Shares are included within the definition of “security” or “securities” as those terms are used in the rules of the Exchange.

Rule 1301B

Commodity Trust Shares: Securities Accounts and Orders of Specialists

(a) The member organization acting as specialist in Commodity Trust Shares is obligated to conduct all trading in the Shares in its specialist account, subject only to the ability to have one or more investment accounts, all of which must be reported to the Exchange. (See Rules 104.12 and 104.13.) In addition, the member organization acting as specialist in Commodity Trust Shares must file with the Exchange in a manner prescribed by the Exchange and keep current a list identifying all accounts for trading in the physical commodities included in, or options, futures or options on futures on, an index underlying an issue of Commodity Trust Shares in which the member organization acts as specialist, or any other derivatives based on such index or based on any commodity included in such index, which the member organization acting as specialist may have or over which it may exercise investment discretion. No member organization acting as specialist in Commodity Trust Shares shall trade in physical commodities included in, or options, futures or options on futures on, an index underlying an issue of Commodity Trust Shares in which the member organization acts as specialist, or any other derivatives based on such index or based on any commodity included in such index, in an account in which a member organization acting as specialist, directly or indirectly, controls trading activities, or has a direct interest in the profits or losses thereof, which has not been reported to the Exchange as required hereby.

(b) In addition to the existing obligations under Exchange rules regarding the production of books and records (see, e.g., Rule 476(a)(11)), the member organization acting as specialist in Commodity Trust Shares shall make available to the Exchange such books, records or other information pertaining to transactions by such entity or any member, allied member, approved person, registered or non-registered employee affiliated with such entity for its or their own accounts in options, futures or options on futures on, an index underlying an issue of Commodity Trust Shares in which the member organization acts as specialist; or in any commodity included in such index; or in any other derivatives based on such index or based on any commodity included in such index, as may be requested by the Exchange.

(c) In connection with trading any physical commodity included in, or options, futures or options on futures on, an index underlying an issue of Commodity Trust Shares in which the member organization acts as specialist, or any other derivatives based on such index (including Commodity Trust Shares) or based on any commodity included in such index, the specialist registered as such in an issue of Commodity Trust Shares shall not use any material nonpublic information received from any person associated with a member or employee of such person regarding trading by such person or employee in the options, futures or options on futures on an index underlying an issue of Commodity Trust Shares in which the member organization acts as specialist; or in any other derivatives on such index; or in any commodity included in such index or any derivatives on such commodity.

Supplementary Material:

.10 The provisions of Rule 1300B (b) and Rule 1301B shall apply to securities listed on the Exchange pursuant to Section 703.19 (“Other Securities”) of the Listed Company Manual where the price of such securities is based in whole or part on the price of (a) a commodity or commodities, (b) any futures contracts or other derivatives based on a commodity or commodities; or (c) any index based on either (a) or (b) above.

II. Self-Regulatory Organization's Statement of the Purpose of, and Statutory Basis for, the Proposed Rule Change

In its filing with the Commission, the NYSE included statements concerning the purpose of, and basis for, the proposed rule change as amended and discussed any comments it received on the proposed rule change. The text of these statements may be examined at the places specified in Item IV below. The Exchange has prepared summaries, set forth in sections A, B and C below, of the most significant aspects of such statements.

A. Self-Regulatory Organization's Statement of the Purpose of, and Statutory Basis for, the Proposed Rule Change

1. Purpose

The Exchange proposes to list and trade Commodity Trust Shares under new NYSE Rules 1300B et seq. The Trust, a Delaware statutory trust, will issue Shares that represent fractional undivided beneficial interests in its net assets. Substantially all of the assets of the Trust consist of its holdings of the limited liability company interests of a commodity pool (“Investing Pool Interests”), which are the only securities in which the Trust may invest. That commodity pool, iShares® GSCI Commodity—Indexed Investing Pool LLC (“Investing Pool”), holds long positions in futures contracts on the GSCI Excess Return Index (“CERFs”), which are listed on the Chicago Mercantile Exchange (“CME”), and will post margin in the form of cash or short-term securities to collateralize these futures positions. According to the Trust's registration statement,^[4] it is the objective of the Trust that the performance of the Shares will correspond generally to the performance of the GSCI Total Return Index (“Index”) before payment of the Trust's and the Investing Pool's expenses and liabilities. The Trust and the Investing Pool are each commodity pools managed by a commodity pool operator registered as such with the Commodity Futures Trading Commission (“CFTC”). Neither the Trust nor the Investing Pool is an investment company registered under the Investment Company Act of 1940 (“Investment Company Act”).

The Shares are intended to constitute a relatively cost-effective means of achieving investment exposure to the performance of the Index, which is intended to reflect the performance of a diversified group of commodities. Although the Shares will not be the exact equivalent of an investment in the underlying futures contracts and Treasury securities represented by the Index, the Shares are intended to provide investors with an alternative way of participating in the commodities market.

a. The Sponsor and Trustee

The Sponsor's primary business function is to act as Sponsor and commodity pool operator of the Trust and manager of the Investing Pool (“Manager”), as discussed below.^[5] The advisor to the Investing Pool (“Advisor”) is Barclays Global Fund Advisors, a California corporation and an indirect subsidiary of Barclays Bank PLC.

As Manager, Barclays Global Investors International, Inc. will serve as commodity pool operator of the Investing Pool and be responsible for its administration. The Manager will arrange for and pay the costs of organizing the Investing Pool. The Manager has delegated some of its responsibilities for administering the Investing Pool to the Administrator, Investors Bank & Trust Company, which in turn, has employed the Investing Pool Administrator and the Tax Administrator (Pricewaterhouse Coopers) to maintain various records on behalf of the Investing Pool.

The trustee of the Trust (“Trustee”) is Barclays Global Investors, N.A., a national banking association affiliated with the Sponsor. The Trustee is responsible for the day-to-day administration of the Trust. Day-to-day administration includes: (i) Processing orders for the creation and redemption of Baskets (as described below, with each Basket an aggregation of 50,000 Shares); (ii) coordinating with the Manager of the Investing Pool the receipt and delivery of consideration transferred to, or by, the Trust in connection with each issuance and redemption of Baskets; and (iii) calculating the net asset value of the Trust on each Business Day.^[6] The Trustee has delegated these responsibilities to the Trust Administrator, Investors Bank & Trust Company, a banking corporation that is not affiliated with the Sponsor or the Trustee.^[7]

b. The Investing Pool

The Investing Pool will hold long positions in CERFs, which are cash-settled futures contracts listed on the CME that have a term of approximately five years after listing and whose settlement at expiration is based on the value of the GSCI Excess Return Index (“GSCI-ER”) at that time. The Investing Pool will also earn interest on the assets used to collateralize its holdings of CERFs. Trading on the CME Globex electronic trading platform of CERFs commenced effective March 12, 2006 for trade date March 13, 2006.

Each CERF is a contract that provides for cash settlement, at expiration, based upon the final settlement value of the GSCI-ER at the expiration of the contract multiplied by a fixed dollar multiplier. The final settlement value is determined for this purpose. Accordingly, a position in CERFs provides the holder with the positive or negative return on the GSCI-ER during the period in which the position is held. On a daily basis, most market participants with positions in CERFs are obligated to pay, or entitled to receive, cash (known as “variation margin”) in an amount equal to the change in the daily settlement level of the CERF from the preceding trading day's settlement level (or, initially, the contract price at which the position was entered into). Specifically, if the daily settlement price of the contract increases over the previous day's price, the seller of the contract must pay the difference to the buyer, and if the daily settlement price is less than the previous day's price, the buyer of the contract must pay the difference to the seller. The Investing Pool, however, and certain other categories of investors, will be required to deposit initial margin equal to 100% of the value of the CERF position at the time it is established.

The GSCI-ER is calculated based on the same commodities included in the Goldman Sachs Commodity Index (“GSCI”), which is a production-weighted index of the prices of a diversified group of futures contracts on physical commodities. The GSCI, the GSCI-ER and the Index are administered, calculated, and published by Goldman, Sachs & Co. (“Index Sponsor”),^[8] a subsidiary of The Goldman Sachs Group Inc. The Index Sponsor is a broker-dealer.^[9]

The GSCI-ER reflects the return of an uncollaterized investment in the contracts comprising the GSCI, and in addition incorporates the economic effect of “rolling” the contracts included in the GSCI as they near expiration. “Rolling” a futures contract means closing out a position in an expiring futures contract and establishing an equivalent position in the contract on the same commodity with the next expiration date. The Index reflects the return of the GSCI-ER, together with the return on specified U.S. Treasury securities that are deemed to have been held to collateralize a hypothetical long position in the futures contracts comprising the GSCI. If Goldman, Sachs & Co. (“Goldman Sachs”) ceases to maintain the GSCI-ER, the Trust, through the Investing Pool, may seek investment results that correspond generally to the Index by holding a fully-collateralized investment in a successor index, or an index that, in the opinion of the Manager, is reasonably similar to the GSCI-ER.^[10]

The Trust, through the Investing Pool, will be a passive investor in CERFs and the cash or Short-Term Securities ^[11] posted as margin to collateralize the Investing Pool's CERF positions. Neither the Trust nor the Investing Pool will engage in any activities designed to obtain a profit from, or to ameliorate losses caused by, changes in the value of CERFs or securities posted as margin.

The Investing Pool, and some other types of market participants, will be required to deposit margin with a value equal to 100% of the value of each CERF position at the time it is established. Those market participants not subject to the 100% margin requirement are required to deposit margin generally with a value of 3% to 5% of the established position. Interest paid on the collateral deposited as margin, net of expenses, will be reinvested by the Investing Pool or, at the Trustee's discretion, may be distributed from time to time to the Shareholders. The Investing Pool's profit or loss on its CERF positions should correlate with increases and decreases in the value of the GSCI-ER, although this correlation will not be exact. The interest on the collateral deposited by the Investing Pool as margin, together with the returns corresponding to the performance of the GSCI-ER, is expected to result in a total return for the Investing Pool that corresponds generally, but is not identical, to the Index. Differences between the returns of the Investing Pool and the Index may be based on, among other factors, any differences between the return on the assets used by the Investing Pool to collateralize its CERF positions and the U.S. Treasury rate used to calculate the return component of the Index, timing differences, differences between the weighting of the Investing Pool's proportion of assets invested in CERFs versus the Index, and the payment of expenses and liabilities by the Investing Pool. The Trust's net asset value will reflect the performance of the Investing Pool, its sole investment.

The Investing Pool will be managed by the Advisor, which will invest all of the Investing Pool's assets in long positions in CERFs and post margin in the form of cash or Short-Term Securities to collateralize the CERF positions. Any cash that the Investing Pool accepts as consideration from the Trust for Investing Pool Interests will be used to purchase additional CERFs, in an amount that the Advisor determines will enable the Investing Pool to achieve investment results that correspond with the Index, and to collateralize the CERFs. According to the Registration Statement, the Advisor will not engage in any activities designed to obtain a profit from, or to ameliorate losses caused by, changes in value of any of the commodities represented by the GSCI or the positions or other assets held by the Investing Pool.

c. Futures Contracts on the GSCI-ER

The assets of the Investing Pool will consist of CERFs and cash or Short-Term Securities posted as margin to collateralize the Investing Pool's CERF positions. Futures contracts and options on futures contracts on the GSCI, which does not reflect the excess return embedded in the GSCI-ER, have been traded on the CME since 1992. CERFs are listed and traded separately from the GSCI futures contracts and options on futures contracts.

CERFs trading is subject to the rules of the CME. According to the Registration Statement, CERFs trade on GLOBEX, the CME's electronic trading system, and do not trade through open outcry on the floor of the CME.^[12] Transactions in CERFs are cleared through the CME clearing house by the trader's futures commission merchant (“FCM”) acting as its agent. Under these clearing arrangements, the CME clearing house becomes the buyer to each member FCM representing a seller of the contract and the seller to each member FCM representing a buyer of the contract. As a result of these clearing arrangements, each trader holding a position in CERFs is subject to the credit risk of the CME clearing house and the FCM carrying its position in CERFs.

Each CERF is a contract that provides for cash settlement, at expiration, based upon the final settlement value of the GSCI-ER at the expiration of the contract, multiplied by a fixed dollar multiplier. The final settlement value is determined for this purpose on the date set forth in the Trust prospectus. On a daily basis, most market participants with positions in CERFs are obligated to pay, or entitled to receive, cash (known as “variation margin”) in an amount equal to the change in the daily settlement level of the CERF from the preceding trading day's settlement level (or, initially, the contract price at which the position was entered into). Specifically, if the daily settlement price of the contract increases over the previous day's price, the seller of the contract must pay the difference to the buyer, and if the daily settlement price is less than the previous day's price, the buyer of the contract must pay the difference to the seller.

Futures contracts also typically require deposits of initial margin as well as payments of daily variation margin as the value of the contracts fluctuate. For most market participants, the initial margin requirement for CERFs is generally expected to be 3% to 5%. Certain market participants (known as “100% margin participants”), however, will be required to deposit with their FCM initial margin in an amount equal to 100% of the value of the CERF on the date the position is established. The FCM, in turn, will be required to deliver to the CME clearing house initial margin in a specified amount and pledge to the clearing house, pursuant to a separate custody arrangement, an amount equal to the remainder of the 100% margin amount posted by 100% margin participants, either from amounts posted by those 100% margin participants or from its own assets. The separate custody arrangement will be either an account with the FCM or a third party custody account.

As a result of these arrangements, a 100% margin participant buying a CERF will be subject to substantially greater initial margin requirements than other market participants, but will not be required to pay any additional amounts to its FCM as variation margin if the value of the CERFs declines. Instead, the FCM will be obligated to make variation margin payments to the clearinghouse in respect of CERFs held by 100% margin participants, which it will withdraw from the separate custody account (and, in turn, from the 100% margin posted by those participants).

If the daily settlement price increases, the FCM will receive variation margin from the clearinghouse for the account of the 100% margin participant, which it will hold in the separate custody account for the benefit of 100% margin participants. The buyer will not, however, be entitled to receive this variation margin from its FCM (until the liquidation or final settlement of its CERF position). The buyer will be entitled to receive interest or other income on the assets it has deposited as margin or that are credited to the custody account on its behalf from time to time.

Upon liquidation or settlement of a CERF, a 100% margin participant will receive from its FCM its initial margin deposit, adjusted for variation margin paid or received by the FCM with respect to the contract during the time it was held by the participant (or the proceeds from liquidation of any investments made with such funds for the benefit of the participant under the terms of its custody arrangement with the carrying FCM).

The 100% margin participants will include any market participant that is: (i) An investment company registered under the Investment Company Act; or (ii) an investment fund, commodity pool, or other similar type of pooled trading vehicle (other than a pension plan or fund) that is offered to the public pursuant to an effective registration statement filed under the Securities Act of 1933, regardless of whether it is also registered under the Investment Company Act , and that has its principal place of business in the United States.

The Investing Pool will be a 100% margin participant. The Investing Pool will satisfy the 100% margin requirement by depositing with the Clearing FCM cash or Short-Term Securities with a value equal to 100% of the value of each long position in CERFs.

According to the Registration Statement, CERFs differ from traditional futures contracts in another significant respect. In contrast to other types of futures contracts, which are typically listed with monthly, bimonthly or quarterly expirations, CERFs will be listed only with approximately five-year expirations. A buyer or seller of CERFs will be able to trade CERFs on the market maintained by the CME and will consequently be able to liquidate its position at any time, subject to the existence of a liquid market. If a party to a CERF wishes to hold its position to expiration, however, it will be necessary to maintain the position for up to five years. According to the Registration Statement, as a CERF nears expiration, it is anticipated, but there can be no assurance, that the CME will list an additional CERF with an approximately five-year expiration.

Creation and redemption of interests in the Trust, and the corresponding creation and redemption of interests in the Investing Pool, will generally be effected through transactions in “exchanges of futures for physicals,” or “EFPs.” EFPs involve contemporaneous transactions in futures contracts and the underlying cash commodity or a closely related commodity. In a typical EFP, the buyer of the futures contract sells the underlying commodity to the seller of the futures contract in exchange for a cash payment reflecting the value of the commodity and the relationship between the price of the commodity and the related futures contract. According to the Registration Statement, in the context of CERFs, CME rules permit the execution of EFPs consisting of simultaneous purchases (sales) of CERFs and sales (purchases) of Shares. This mechanism will generally be used by the Trust in connection with the creation and redemption of Baskets. Specifically, it is anticipated that an “Authorized Participant” (defined below) requesting the creation of additional Baskets typically will transfer CERFs and cash (or, in the discretion of the Trustee, Short-Term Securities in lieu of cash) to the Trust in return for Shares.^[13]

The Trust will simultaneously contribute to the Investing Pool the CERFs (and any cash or securities) received from the Authorized Participant in return for an increase in its Investing Pool Interests. If an EFP is executed in connection with the redemption of one or more Baskets, an Authorized Participant will transfer to the Trust the interests being redeemed and the Trust will transfer to the Authorized Participant CERFs, cash or Short-Term Securities. In order to obtain the CERFs, cash or Short-Term Securities to be transferred to the Authorized Participant, the Trust will redeem an equivalent portion of its interest in the Investing Pool Interests.

d. The Index and the GSCI-ER

The Index and the GSCI-ER were established in May of 1991. The Index reflects the value of an investment in the GSCI-ER together with a Treasury bill return. The GSCI-ER reflects the returns that are potentially available through a rolling uncollaterized investment in the contracts comprising the GSCI.

Because futures contracts have scheduled expirations, or delivery months, as one contract nears expiration it becomes necessary to close out the position in that delivery month and establish a position in the next available delivery month. This process is referred to as “rolling” the position forward. The GSCI-ER is designed to reflect the return from rolling each contract included in the GSCI in this manner into the next available delivery month as it nears expiration. This is accomplished by selling the position in the first delivery month and purchasing a position of equivalent value in the second delivery month. If the price of the second contract is lower than the price of the first contract, the “rolling” process results in a greater quantity of the second contract being acquired for the same value. Conversely, if the price of the second contract is higher than the price of the first contract, the “rolling” process results in a smaller quantity of the second contract being acquired for the same value.

The GSCI itself is an index on a production-weighted basket of principal physical commodities that satisfy specified criteria. The GSCI reflects the level of commodity prices at a given time and is designed to be a measure of the performance over time of the markets for these commodities. The commodities represented in the GSCI are those physical commodities on which active and liquid contracts are traded on trading facilities in major industrialized countries. The commodities included in the GSCI are weighted, on a production basis, to reflect the relative significance (in the view of the Index Sponsor, in consultation with its Policy Committee described below) of those commodities to the world economy. The fluctuations in the level of the GSCI are intended generally to correlate with changes in the prices of those physical commodities in global markets.

The Index Sponsor makes the official calculations of the value of the Index.^[14] At present, this calculation is performed continuously and is reported on Reuters Page GSCI and is updated on Reuters at least every fifteen seconds during NYSE trading hours for the Shares and during business hours on each Business Day on which the offices of Goldman, Sachs in New York City are open for business. In the event that the Exchange is open for business on a day that is not a GSCI Business Day, the Exchange will not permit trading of the Shares on that day.^[15] The settlement prices for the Index and GSCI-ER are also reported on Reuters Page GSCI at the end of each GSCI Business Day and on Bloomberg page GSCIER index.

e. The Policy Committee

The Index Sponsor has established a Policy Committee to assist it with the operation of the GSCI.^[16] The principal purpose of the Policy Committee is to advise the Index Sponsor with respect to, among other things, the calculation of the GSCI, the effectiveness of the GSCI as a measure of commodity futures market performance and the need for changes in the composition or the methodology of the GSCI. The Policy Committee acts solely in an advisory and consultative capacity. All decisions with respect to the composition, calculation and operation of the GSCI are made by the Index Sponsor.^[17]

The Policy Committee generally meets in October of each year. Prior to the meeting, the Index Sponsor determines the commodities to be included in the GSCI for the following calendar year and the weighting factors for each commodity. The Policy Committee's members receive the proposed composition of the GSCI in advance of the meeting and discuss the composition at the meeting. The Index Sponsor also consults the Policy Committee on any other significant matters with respect to the calculation and operation of the GSCI. The Policy Committee may, if necessary or practicable, meet at other times during the year as issues arise that warrant its consideration.

The Policy Committee currently consists of eight persons, three of whom are employees of the Index Sponsor or its affiliates and five of whom are not affiliated with the Index Sponsor.

f. Composition of the GSCI

Because the value of the Index (which the Shares track) reflects the futures contracts included in the GSCI, the Exchange describes below the index methodology for the GSCI.^[18] In order to be included in the GSCI, a contract must satisfy the following eligibility criteria:

(i) The contract must:

(a) Be in respect of a physical commodity and not a financial commodity;

(b) Have a specified expiration or term, or provide in some other manner for delivery or settlement at a specified time, or within a specified period, in the future; and

(c) Be available, at any given point in time, for trading at least five months prior to its expiration or such other date or time period specified for delivery or settlement.

(ii) The commodity must be the subject of a contract that:

(a) Is denominated in U.S. dollars;

(b) Is traded on or through an exchange, facility or other platform, referred to as a “trading facility,” that has its principal place of business or operations in a country that is a member of the Organization for Economic Cooperation and Development and:

(1) Makes price quotations generally available to its members or participants (and, if the Index Sponsor is not such a member or participant, to the Index Sponsor) in a manner and with a frequency that is sufficient to provide reasonably reliable indications of the level of the relevant market at any given point in time;

(2) Makes reliable trading volume information available to the Index Sponsor with at least the frequency required by the Index Sponsor to make the monthly determinations;

(3) Accepts bids and offers from multiple participants or price providers; and

(4) Is accessible by a sufficiently broad range of participants.

(iii) The price of the relevant contract that is used as a reference or benchmark by market participants, referred to as the “daily contract reference price,” generally must have been available on a continuous basis for at least two years prior to the proposed date of inclusion in the GSCI. In appropriate circumstances, however, the Index Sponsor, in consultation with its Policy Committee, may determine that a shorter time period is sufficient or that historical daily contract reference prices for that contract may be derived from daily contract reference prices for a similar or related contract. The daily contract reference price may be (but is not required to be) the settlement price or other similar price published by the relevant trading facility for purposes of margining transactions or for other purposes.

(iv) At and after the time a contract is included in the GSCI, the daily contract reference price for that contract must be published between 10 a.m. and 4 p.m., New York time, on each Business Day relating to that contract by the trading facility on or through which it is traded and must generally be available to all members of, or participants in, that trading facility (and, if the Index Sponsor is not such a member or participant, to the Index Sponsor) on the same day from the trading facility or through a recognized third-party data vendor. Such publication must include, at all times, daily contract reference prices for at least one expiration or settlement date that is five months or more from the date the determination is made, as well as for all expiration or settlement dates during that five-month period.

(v) Volume data with respect to the contract must be available for at least the three months immediately preceding the date on which the determination is made.

(vi) A contract that is not included in the GSCI at the time of determination and that is based on a commodity that is not represented in the GSCI at that time must, in order to be added to the GSCI at that time, have a total dollar value traded, over the relevant period, as the case may be and annualized, of at least $15 billion. The total dollar value traded is the dollar value of the total quantity of the commodity underlying transactions in the relevant contract over the period for which the calculation is made, based on the average of the daily contract reference prices on the last day of each month during the period.

(vii) A contract that is already included in the GSCI at the time of determination and that is the only contract on the relevant commodity included in the GSCI must, in order to continue to be included in the GSCI after that time, have a total dollar value traded, over the relevant period, as the case may be and annualized, of at least $5 billion and at least $10 billion during at least one of the three most recent annual periods used in making the determination.

(viii) A contract that is not included in the GSCI at the time of determination and that is based on a commodity on which there are one or more contracts already included in the GSCI at that time must, in order to be added to the GSCI at that time, have a total dollar value traded, over the relevant period, as the case may be and annualized, of at least $30 billion.

(ix) A contract that is already included in the GSCI at the time of determination and that is based on a commodity on which there are one or more contracts already included in the GSCI at that time must, in order to continue to be included in the GSCI after that time, have a total dollar value traded, over the relevant period, as the case may be and annualized, of at least $10 billion and at least $20 billion during at least one of the three most recent annual periods used in making the determination.

(x) A contract that is:

(a) Already included in the GSCI at the time of determination must, in order to continue to be included after that time, have a reference percentage dollar weight of at least 0.10%. The “reference percentage dollar weight” of a contract represents the current value of the quantity of the underlying commodity that is included in the Index at a given time. This figure is determined by multiplying the contract production weight of a contract, or “CPW,” by the average of its daily contract reference prices on the last day of each month during the relevant period. These amounts are summed for all contracts included in the GSCI and each contract's percentage of the total is then determined. The CPW of a contract is its weight in the Index.

(b) Not included in the GSCI at the time of determination must, in order to be added to the GSCI at that time, have a reference percentage dollar weight of at least 0.75%.

(xi) In the event that two or more contracts on the same commodity satisfy the eligibility criteria:

(a) Such contracts will be included in the GSCI in the order of their respective total quantity traded during the relevant period (determined as the total quantity of the commodity underlying transactions in the relevant contract), with the contract having the highest total quantity traded being included first, provided that no further contracts will be included if such inclusion would result in the portion of the GSCI attributable to that commodity exceeding a particular level.

(b) If additional contracts could be included with respect to several commodities at the same time, that procedure is first applied with respect to the commodity that has the smallest portion of the GSCI attributable to it at the time of determination. Subject to the other eligibility criteria described above, the contract with the highest total quantity traded on that commodity will be included. Before any additional contracts on the same commodity or on any other commodity are included, the portion of the GSCI attributable to all commodities is recalculated. The selection procedure described above is then repeated with respect to the contracts on the commodity that then has the smallest portion of the GSCI attributable to it.

Beginning in 2007, in order for a contract to be included in the GSCI: (i) The trading facility in which the contract is traded must allow market participants to execute spread transactions, through a single order entry, between the pairs of contract expirations included in the GSCI that at any given point in time will be involved in the rolls to be effected in the next three roll periods; and (ii) a contract that is not included in the GSCI at the time of determination must, in order to be added to the GSCI at that time, have a reference percentage dollar weight of at least 1.00%.

The contracts currently included in the GSCI are all futures contracts traded on the New York Mercantile Exchange, Inc. (“NYM”), the ICE Futures (“ICE”), the CME, the Chicago Board of Trade (“CBT”), the Coffee, Sugar & Cocoa Exchange, Inc. (“CSC”), the New York Cotton Exchange (“NYC”), the Kansas City Board of Trade (“KBT”), the COMEX Division of the New York Mercantile Exchange, Inc. (“CMX”) and the London Metal Exchange (“LME”).

The futures contracts currently included in the GSCI, their percentage dollar weights (as of January 20, 2006), their market symbols and the exchanges on which they are traded, trading hours (New York time), Average Daily Trading Volume (“ADTV”) for 2005, and units per contract are as follows:

The quantity of each of the contracts included in the GSCI is determined on the basis of a five-year average, referred to as the “world production average,” of the production quantity of the underlying commodity as published by the United Nations Statistical Yearbook, the Industrial Commodity Statistics Yearbook and other official sources. However, if a commodity is primarily a regional commodity, based on its production, use, pricing, transportation or other factors, the Index Sponsor, in consultation with its Policy Committee, may calculate the weight of that commodity based on regional, rather than world, production data. At present, natural gas is the only commodity the weights of which are calculated on the basis of regional production data, with the relevant region defined as North America.

The five-year moving average is updated annually for each commodity included in the GSCI, based on the most recent five-year period (ending approximately two years prior to the date of calculation and moving backwards) for which complete data for all commodities is available. The CPWs used in calculating the GSCI are derived from world or regional production averages, as applicable, of the relevant commodities, and are calculated based on the total quantity traded for the relevant contract and the world or regional production average, as applicable, of the underlying commodity. However, if the volume of trading in the relevant contract, as a multiple of the production levels of the commodity, is below specified thresholds, the CPW of the contract is reduced until the threshold is satisfied. This is designed to ensure that trading in each contract is sufficiently liquid relative to the production of the commodity.

In addition, the Index Sponsor performs this calculation on a monthly basis and, if the multiple of any contract is below the prescribed threshold, the composition of the GSCI is reevaluated, based on the criteria and weighting procedure described above. This procedure is undertaken to allow the GSCI to shift from contracts that have lost substantial liquidity into more liquid contracts during the course of a given year. As a result, it is possible that the composition or weighting of the GSCI will change on one or more of these monthly evaluation dates. The likely circumstances under which the Index Sponsor would be expected to change the composition of the Index during a given year, however, are: (i) A substantial shift of liquidity away from a contract included in the Index as described above; or (ii) an emergency, such as a natural disaster or act of war or terrorism, that causes trading in a particular contract to cease permanently or for an extended period of time. In either event, the Index Sponsor will consult with the Policy Committee in connection with the changes to be made and will publish the nature of the changes, through Web sites, news media or other outlets, with as much prior notice to market participants as is reasonably practicable. Moreover, regardless of whether any changes have occurred during the year, the Index Sponsor reevaluates the composition of the GSCI, in consultation with its Policy Committee, at the conclusion of each year, based on the above criteria. Other commodities that satisfy that criteria, if any, will be added to the GSCI. Commodities included in the GSCI that no longer satisfy that criteria, if any, will be deleted.

The Index Sponsor, in consultation with its Policy Committee, also determines whether modifications in the selection criteria or the methodology for determining the composition and weights of and for calculating the GSCI are necessary or appropriate in order to assure that the GSCI represents a measure of commodity market performance. The Index Sponsor has the discretion to make any such modifications, in consultation with its Policy Committee.

g. Total Dollar Weight of the GSCI

The total dollar weight of the GSCI is the sum of the dollar weight of each of the underlying commodities. The dollar weight of each such commodity on any given day is equal to:

• The daily contract reference price;
• Multiplied by the appropriate CPW; and
• During a roll period, the appropriate “roll weights” (discussed below).

The daily contract reference price used in calculating the dollar weight of each commodity on any given day is the most recent daily contract reference price made available by the relevant trading facility, except that the daily contract reference price for the most recent prior day will be used if the exchange is closed or otherwise fails to publish a daily contract reference price on that day. In addition, if the trading facility fails to make a daily contract reference price available or publishes a daily contract reference price that, in the reasonable judgment of the Index Sponsor, reflects manifest error, the relevant calculation will be delayed until the price is made available or corrected; provided, that, if the price is not made available or corrected by 4 p.m. New York time, the Index Sponsor may, if it deems that action to be appropriate under the circumstances, determine the appropriate daily contract reference price for the applicable futures contract in its reasonable judgment for purposes of the relevant GSCI calculation.^[19]

h. Calculation of the GSCI-ER

The value of the GSCI-ER on any GSCI Business Day is equal to the product of: (i) The value of the GSCI-ER on the immediately preceding GSCI Business Day multiplied by (ii) one plus the sum of the contract daily return ^[20] on the GSCI Business Day on which the calculation is made. The value of the GSCI-ER has been normalized such that its hypothetical level on January 2, 1970 was 100.

i. Calculation of the Index

The value of the Index on any GSCI Business Day is equal to the product of: (i) The value of the Index on the immediately preceding GSCI Business Day multiplied by (ii) one plus the sum of the contract daily return and the Treasury bill return on the GSCI Business Day on which the calculation is made, multiplied by (iii) one plus the Treasury bill return for each non-GSCI Business Day since the immediately preceding GSCI Business Day. The Treasury bill return is the return on a hypothetical investment in the GSCI at a rate equal to the interest rate on a specified U.S. Treasury bill.

j. Valuation of CERFs; Computation of Trust's Net Asset Value

On each Business Day on which the NYSE is open for regular trading, as soon as practicable after the close of regular trading of the Shares on the NYSE (normally, 4:15 p.m., New York time), the Trustee will determine the net asset value (“NAV”) of the Trust and per share as of that time.

The Trustee will value the Trust's assets based upon the determination by the Manager, which may act through the Investing Pool Administrator, of the NAV of the Investing Pool. The Manager will determine the NAV of the Investing Pool as of the same time that the Trustee determines the NAV of the Trust.

The Manager will value the Investing Pool's long position in CERFs on the basis of that day's announced CME settlement price for the CERF. The value of the Investing Pool's CERF position (including any related margin) will equal the product of: (i) The number of CERF contracts owned by the Investing Pool and (ii) the settlement price on the date of calculation. If there is no announced CME settlement price for the CERF on a Business Day, the Manager will use the most recently announced CME settlement price unless the Manager determines that that price is inappropriate as a basis for evaluation. The daily settlement price for the CERF is established by the CME shortly after the close of trading in Chicago at 2:40 p.m. New York time on each trading day.^[21]

Once the value of the CERFs and interest earned on any assets posted as margin and any other assets of the Investing Pool has been determined, the Manager will subtract all accrued expenses and liabilities of the Investing Pool as of the time of calculation in order to calculate the net asset value of the Investing Pool. The Manager, or the Investing Pool Administrator on its behalf, will then calculate the value of the Trust's Investing Pool Interest and provide this information to the Trustee.

Once the value of the Trust's Investing Pool Interests have been determined and provided to the Trustee, the Trustee will subtract all accrued expenses and other liabilities of the Trust from the total value of the assets of the Trust, in each case as of the calculation time. The resulting amount is the NAV of the Trust. The Trustee will determine the NAV per Share by dividing the NAV of the Trust by the number of Shares outstanding at the time the calculation is made.

The NAV for each Business Day on which the NYSE is open for regular trading will be distributed through major market data vendors and will be published online at http://www.iShares.com, or any successor thereto. The Trust will update the NAV as soon as practicable after each subsequent NAV is calculated.

k. Creations of Baskets

The Trust will offer Shares on a continuous basis on each business day, but only in Baskets consisting of 50,000 Shares. Baskets will be typically issued only in exchange for an amount of CERFs and cash (or, in the discretion of the Trustee, Short-Term Securities in lieu of cash) equal to the Basket Amount for the Business Day on which the creation order was received by the Trustee. The Basket Amount for a Business Day will have a per Share value equal to the NAV as of such day. However, orders received by the Trustee after 2:40 p.m., New York time, will be treated as received on the next following Business Day. The Trustee will notify the Authorized Participants of the Basket Amount on each Business Day prior to the opening of the Exchange.

Before the Trust will issue any Baskets to an Authorized Participant, that Authorized Participant must deliver to the Trustee a written creation order indicating the number of Baskets it intends to purchase and providing other details with respect to the procedures by which the Baskets will be transferred. The Trustee will acknowledge the creation order unless it or the Sponsor decides to refuse the order as described in the prospectus.

Upon the transfer of the required consideration of CERFs and cash (or, in the discretion of the Trustee, Short-Term Securities in lieu of cash) in the amounts, and to the accounts, specified by the Trustee, and the Trustee's transaction fee per Basket (described below), the Trustee will deliver the appropriate number of Baskets to the Depository Trust Company (“DTC”) account of the Authorized Participant. In limited circumstances and with the approval of the Trustee, Baskets may be created for cash, in which case the Authorized Participant will be required to pay any additional issuance costs, including the costs to the Investing Pool of establishing the corresponding CERF position.

Only Authorized Participants can transfer the required consideration and receive Baskets in exchange. Authorized Participants may act for their own accounts or as agents for broker-dealers, custodians, and other securities market participants that wish to create or redeem Baskets. An Authorized Participant will have no obligation to create or redeem Baskets for itself or on behalf of other persons. An order for one or more baskets may be placed by an Authorized Participant on behalf of multiple clients. The Sponsor and the Trustee will maintain a current list of Authorized Participants.

No Shares will be issued unless and until the Trustee receives confirmation that: (i) The required consideration has been received in the account or accounts specified by the Trustee; and (ii) the Manager confirms that Investing Pool Interests with an initial value equal to the consideration received for the Shares have been issued to the Trust. It is expected that delivery of the Shares will be made against transfer of consideration on the next Business Day (T+1) following the Business Day on which the creation order is received by the Trustee. If the Trustee has not received the required consideration for the Shares to be delivered on the delivery date, by 11 a.m., New York time, the Trustee may cancel the creation order.^[22]

l. Redemptions of Baskets

Authorized Participants may typically surrender Baskets in exchange only for an amount of CERFs and cash (or, in the discretion of the Trustee, Short-Term Securities in lieu of cash) equal to the Basket Amount on the Business Day the redemption request is received by the Trustee. However, redemption requests received by the Trustee after 2:40 p.m., New York time (or, on any day on which the CME is scheduled to close early, after the close of trading of CERFs on the CME on such day), will be treated as received on the next following Business Day. Holders of Baskets who are not Authorized Participants will be able to redeem their Baskets only through an Authorized Participant. It is expected that Authorized Participants may redeem Baskets for their own accounts or on behalf of Shareholders who are not Authorized Participants, but they are under no obligation to do so.

Before surrendering Baskets for redemption, an Authorized Participant must deliver to the Trustee a written request indicating the number of Baskets it intends to redeem and providing other details with respect to the procedures by which the required Basket Amount will be transferred. The Trustee will acknowledge the redemption order unless it or the Sponsor decides to refuse the redemption order as described in the Trust prospectus.

After the delivery by the Authorized Participant to the Trustee's DTC account of the total number of Shares to be redeemed by an Authorized Participant, the Trustee will deliver to the order of the redeeming Authorized Participant redemption proceeds consisting of CERFs and cash (or, in the discretion of the Trustee, Short-term Securities in lieu of cash). In connection with a redemption order, the redeeming Authorized Participant authorizes the Trustee to deduct from the proceeds of redemption a transaction fee per Basket (described below). In limited circumstances and with the approval of the Trustee, Baskets may be redeemed for cash, in which case the Authorized Participants will be required to pay any additional redemption costs, including the costs to the Investing Pool of liquidating the corresponding CERF position. The Trust will receive these redemption proceeds pursuant to the Trust's contemporaneous redemption of Investing Pool Interests of corresponding value. Shares can be surrendered for redemption only in Baskets consisting of 50,000 Shares each.

It is expected that delivery of the CERFs, cash or Short-term Securities to the redeeming Shareholder will be made against transfer of the Baskets on the next Business Day following the Business Day on which the redemption request is received by the Trustee. If the Trustee's DTC account has not been credited with the total number of Shares to be redeemed pursuant to the redemption order by 11 a.m., New York time, on the delivery date, the Trustee may cancel the redemption order. DTC will accept the Shares for settlement through its book-entry settlement system. Shares do not have any voting rights.

m. Fees and Expenses of the Trustee

Each order for the creation of Baskets must be accompanied by a payment to the Trustee of a transaction fee per Basket of $10.00 multiplied by the number of CERFs included in the Basket Amount. For redemption orders, the redeeming Authorized Participant will authorize the Trustee to deduct from the proceeds of the redemption a transaction fee per Basket equal to $10.00 multiplied by the number of CERFs included in the Basket Amount, plus any expenses, taxes or charges (such as stamp taxes or stock transfer taxes or fees) related to the creation or surrender for redemption. The Trustee will be entitled to reimburse itself from the assets of the Trust for all expenses and disbursements incurred by it for extraordinary services it may provide to the Trust or in connection with any discretionary action the Trustee may take to protect the Trust or the interests of the holders to the extent not paid by the Sponsor.

n. Dissemination of Information Relating to the Shares, Trust Holdings, and Relevant Indices

The Web site for the Trust (http://www.iShares.com), which will be publicly accessible at no charge, will contain the following information: (i) The prior Business Day's NAV and the reported closing price; (ii) the mid-point of the bid-ask price in relation to the NAV as of the time the NAV is calculated (the “Bid-Ask Price”); (iii) calculation of the premium or discount of such price against such NAV; (iv) data in chart form displaying the frequency distribution of discounts and premiums of the Bid-Ask Price against the NAV, within appropriate ranges for each of the four previous calendar quarters; (v) the prospectus; (vi) the holdings of the Trust, including CERFs, cash and Treasury securities; (vii) the Basket Amount; and (viii) other applicable quantitative information. The Exchange on its Web site at http://www.nyse.com will include a hyperlink to the Trust's Web site at http://www.iShares.com.

As described above, the NAV for the Fund will be calculated and disseminated daily. The NYSE also intends to disseminate, during NYSE trading hours for the Trust on a daily basis by means of CTA/CQ High Speed Lines information with respect to the Indicative Value (as discussed below), recent NAV, and Shares outstanding. The Exchange will also make available on http://www.nyse.com daily trading volume, closing prices, and the NAV.

Real-time information is available about the Trust's holdings in the Investing Pool. Various data vendors and news publications publish futures prices and data. Futures quotes and last sale information for the commodities underlying the Index and the CERFs are widely disseminated through a variety of market data vendors worldwide, including Bloomberg and Reuters. In addition, complete real-time data for such futures, including the CERFs, is available by subscription from Reuters and Bloomberg. The futures exchanges or which the underlying commodities and CERFs trade also provide delayed futures information on current and past trading sessions and market news generally free of charge on their respective Web sites. The specific contract specifications for the futures contracts are also available from the futures exchanges on their Web sites as well as other financial informational sources.

As stated above, major market data vendors will disseminate at least every 15 seconds (during the time that the Shares trade on the Exchange) the GSCI and Index values. Additionally, major market data vendors will disseminate at least every 15 seconds (during the time that the Shares trade on the Exchange) the value of the GSCI-ER, which the CERFs (held by the Investing Pool) trading on CME are designed to track.^[23] Daily settlement values for the GSCI, the Index, and the GSCI-ER are also widely disseminated.^[24]

o. Indicative Value

In order to provide updated information relating to the Trust for use by investors, professionals, and other persons, the Exchange will disseminate through the facilities of CTA an updated Indicative Value on a per Share basis as calculated by Bloomberg. The Indicative Value will be disseminated at least every 15 seconds from 9:30 a.m. to 4:15 p.m. New York time. The Indicative Value will be calculated based on the cash and collateral in a Basket Amount divided by 50,000, adjusted to reflect the market value of the investments held by the Investing Pool, i.e., CERFs.^[25] The Indicative Value will not reflect price changes to the price of an underlying commodity between the close of trading of the futures contract at the relevant futures exchange and the close of trading on the NYSE at 4:15 p.m. New York time.

When the market for futures trading for each of the Index commodities is open, the Indicative Value can be expected to closely approximate the value per Share of the Basket Amount. However, during NYSE trading hours when the futures contracts have ceased trading, spreads and resulting premiums or discounts may widen, and, therefore, increase the difference between the price of the Shares and the NAV of the Shares. Indicative Value on a per Share basis disseminated during NYSE trading hours should not be viewed as a real time update of the NAV, which is calculated only once a day. The Exchange believes that dissemination of the Indicative Value provides additional information that is not otherwise available to the public and is useful to professionals and investors in connection with the Shares trading on the Exchange or creation or redemption of the Shares.

p. Other Characteristics of the Shares

i. General Information

A minimum of three Baskets, representing 150,000 Shares, will be outstanding at the commencement of trading on the Exchange.

Trading in Shares on the Exchange will be effected normally until 4:15 p.m. each day on which the Exchange is open for trading. The minimum trading increment for Shares on the Exchange will be $0.01.

ii. Fees

The Exchange original listing fee applicable to the listing of the Trust will be $5,000. The annual continued listing fee for the Trust will be $2,000.

iii. Continued Listing Criteria

Under the applicable continued listing criteria, the Shares may be delisted as follows: (i) Following the initial twelve-month period beginning upon the commencement of trading of the Shares, there are fewer than 50 record and/or beneficial holders of the Shares for 30 or more consecutive trading days; (ii) the value of the Index ceases to be calculated or available on at least a 15-second basis from a source unaffiliated with the Sponsor, the Trust or the Trustee; (iii) the Indicative Value ceases to be available on at least a 15-second delayed basis; or (iv) such other event shall occur or condition exist that, in the opinion of the Exchange, makes further dealings on the Exchange inadvisable. In addition, the Exchange will remove Shares from listing and trading upon termination of the Trust.

Additionally, the Exchange will file a proposed rule change pursuant to Rule 19b-4 under the Act,^[26] seeking approval to continue trading the Shares and unless approved, the Exchange will commence delisting the Shares if:

Additionally, the Exchange will file a proposed rule change pursuant to Rule 19b-4 under the Act,^[27] seeking approval to continue trading the Notes and unless approved, the Exchange will commence delisting the Shares if:

• The Index Sponsor substantially change either the Index component selection methodology or the weighting methodology;
• If a new component is added to the Index (or pricing information is used for a new or existing component) that constitutes more than 10% of the weight of the Index with whose principal trading market the Exchange does not have a comprehensive surveillance sharing agreement; ^[28] or

• If a successor or substitute index is used in connection with the Shares. The filing will address, among other things the listing and trading characteristics of the successor or substitute index and the Exchange's surveillance procedures applicable thereto.

q. Exchange Trading Rules and Policies

The Shares are considered “securities” pursuant to NYSE Rule 3 and are subject to all applicable trading rules.

The Trust is exempt from corporate governance requirements in section 303A of the NYSE Listed Company Manual, including the Exchange's audit committee requirements in Section 303A.06.^[29]

The Exchange will adopt new NYSE Rule 1300B (“Commodity Trust Shares”) to deal with issues related to the trading of the Shares. Specifically, for purposes of NYSE Rules 13 (“Definitions of Orders”), 36.30 (“Communications Between Exchange and Members’ Offices”), 98 (“Restrictions on Approved Person Associated with a Specialist's Member Organization), 104 (“Dealings by Specialists”), 105(m) (“Guidelines for Specialist's” Specialty Stock Option Transactions Pursuant to Rule 105”), 460.10 (“Specialists Participating in Contests”), 1002 (“Availability of Automatic Feature”), and 1005 (“Order May Not Be Broken Into Smaller Accounts”), the Shares will be treated similar to Investment Company Units.^[30]

When these Rules discuss Investment Company Units, references to the word index (or derivative or similar words) will be deemed to be references to the applicable commodity or commodity index price and reference to the word security (or derivative or similar words) will be deemed to be references to the Commodity Index Trust Shares.

The Exchange does not currently intend to exempt Commodity Trust Shares from the Exchange's “Market-on-Close/Limit-on-Close/Pre-Opening Price Indications” Policy, although the Exchange may do so by means of a rule change in the future if, after having experience with the trading of the Shares, the Exchange believes such an exemption is appropriate.

i. Trading Halts

With respect to trading halts, the Exchange may consider all relevant factors in exercising its discretion to halt or suspend trading in the Shares. Trading on the Exchange in the Shares may be halted because of market conditions or for reasons that, in the view of the Exchange, make trading in the Shares inadvisable. These may include (1) the extent to which trading is not occurring in the underlying commodities or (2) whether other unusual conditions or circumstances detrimental to the maintenance of a fair and orderly market are present. In addition, trading in Shares is subject to trading halts caused by extraordinary market volatility pursuant to Exchange's “circuit breaker” rule.^[31] The Exchange will halt trading in the Shares if the value of the Index is no longer calculated or available on at least a 15-second basis through one or more major market data vendors during the time the Shares trade on the NYSE, or if the Indicative Value per Share updated at least every 15 seconds is no longer calculated or available.^[32]

ii. Specialists' Trading Obligations

New Supplementary Material .10 to proposed NYSE Rule 1301B would apply the provisions of proposed Rule 1300B(b) and Rule 1301B to certain securities listed on the Exchange pursuant to section 703.19 (“Other Securities”) of the NYSE Listed Company Manual. Specifically, proposed NYSE Rules 1300B(b) and 1301B will apply to securities listed under section 703.19 where the price of such securities is based in whole or part on the price of a commodity or commodities, a commodities index, or any futures contracts or other derivatives based thereon. Examples of the securities to which Supplementary Material .10 will apply are the subjects of the following File Nos.: (i) SR-NYSE-2006-16 (proposal to list and trade Index-Linked Securities of Barclays Bank PLC linked to the performance of the Dow Jones-AIG Commodity Index Total Return^TM); (ii) SR-NYSE-2006-19 (proposal to list and trade Index-Linked Securities of Barclays Bank PLC linked to the performance of the Goldman Sachs Crude Oil Total Return Index^TM); and (iii) File No. SR-NYSE-2006-20 (proposal to list and trade Index-Linked Securities of Barclays Bank PLC linked to the performance of the GSCI Total Return Index ^TM).

As a result of application of proposed NYSE Rule 1300B(b), the specialist in a relevant security listed under section 703.19 (“Section 703.19 security”), the specialist's member organization and other specified persons will be prohibited under paragraph (m) of NYSE Rule 105 Guidelines from acting as market maker or functioning in any capacity involving market-making responsibilities in the physical commodities included in, or options, futures or options on futures on, the index underlying the relevant section 703.19 security, or any other derivatives (collectively, “derivative instruments”) based on such index. A specialist entitled to an exemption under NYSE Rule 98 from paragraph (m) of NYSE Rule 105 Guidelines could act in a market making capacity in physical commodities included in, or derivative instruments based on such index, other than as a specialist in the same section 703.19 security in another market center.

Under proposed NYSE Rule 1301B(a), the member organization acting as specialist in a Section 703.19 security: (i) Will be obligated to conduct all trading in the specialty security in its specialist account, (subject only to the ability to have one or more investment accounts, all of which must be reported to the Exchange); (ii) will be required to file with the Exchange and keep current a list identifying all accounts for trading in the physical commodities included in, or derivative instruments based on the relevant index, which the member organization acting as specialist may have or over which it may exercise investment discretion; and (iii) will be prohibited from trading in physical commodities included in, or derivative instruments based on the relevant index, in an account in which a member organization acting as specialist, controls trading activities which have not been reported to the Exchange as required by proposed NYSE Rule 1301B.

Under Rule 1301B(b), the member organization acting as specialist in a relevant section 703.19 security will be required to make available to the Exchange such books, records or other information pertaining to transactions by the member organization and other specified persons for its or their own accounts in derivative instruments on an index underlying such section 703.19 security or any commodity included in such index, as may be requested by the Exchange. This requirement is in addition to existing obligations under Exchange rules regarding the production of books and records. Under proposed NYSE Rule 1301B(c), in connection with trading derivative instruments based on an index underlying a relevant section 703.19 security in which the member organization acts as specialist, the specialist could not use any material nonpublic information received from any person associated with a member or employee of such person regarding trading by such person or employee in derivative instruments based on the underlying index or in any commodity included in such index.

r. Surveillance

The Exchange represents that its surveillance procedures are adequate to properly monitor the trading of the Shares and the Index components. The Exchange will rely upon existing NYSE surveillance procedures governing equities with respect to surveillance of the Shares. The Exchange believes that these procedures are adequate to monitor Exchange trading of the Shares, to detect violations of Exchange rules, consequently deterring manipulation. In this regard, the Exchange currently has the authority under NYSE Rule 476 to request the Exchange specialist in the Shares to provide NYSE Regulation with information that the specialist uses in connection with pricing the Shares on the Exchange, including specialist proprietary or other information regarding securities, commodities, futures, options on futures or other derivative instruments. The Exchange believes it also has authority to request any other information from its members—including floor brokers, specialists and “upstairs” firms—to fulfill its regulatory obligations.^[33]

With regard to the Index components, the Exchange can obtain market surveillance information, including customer identity information, with respect to transactions occurring on the New York Mercantile Exchange (“NYMEX”), the Kansas City Board of Trade, ICE and the LME, pursuant to its comprehensive information sharing agreements with each of those exchanges. All of the other trading venues on which current Index components are traded are members of the Intermarket Surveillance Group (“ISG”) and the Exchange therefore has access to all relevant trading information with respect to those contracts without any further action being required on the part of the Exchange. If at any time the Index Sponsor includes in the Index a contract traded on any other market which is not a member or affiliate of the ISG and with respect to which the Exchange does not have a preexisting comprehensive information sharing agreement previously reviewed and found acceptable by the Commission, then, prior to the inclusion of such contract in the Index, the Exchange will: (i) Enter into adequate information sharing arrangements with that other market; and (ii) contact the Commission to discuss measures that may be appropriate under the circumstances, including whether the Exchange should file proposed rule change seeking Commission approval prior to the inclusion of the new contract in the Index.

s. Due Diligence

Before a member, member organization, allied member or employee thereof recommends a transaction in the Shares, such person must exercise due diligence to learn the essential facts relative to the customer pursuant to NYSE Rule 405, and must determine that the recommendation complies with all other applicable Exchange and Federal rules and regulations. A person making such recommendation should have a reasonable basis for believing, at the time of making the recommendation, that the customer has sufficient knowledge and experience in financial matters that he or she may reasonably be expected to be capable of evaluating the risks and any special characteristics of the recommended transaction, and is financially able to bear the risks of the recommended transaction.

t. Information Memo

The Exchange will distribute an information memo (“Memo”) to its members in connection with the trading in the Shares. The Memo will discuss the special characteristics and risks of trading this type of security. Specifically, the Memo, among other things, will discuss what the Shares are, that Shares are not individually redeemable but are redeemable only in Baskets of 50,000 shares or multiples thereof, how a Basket is created and redeemed, applicable Exchange rules, the Indicative Value, dissemination information, trading information and the applicability of suitability rules, and exemptive relief granted by the Commission from certain rules under the Act.^[34] The Memo will also reference that the Trust is subject to various fees and expenses described in the Registration Statement. Finally, the Memo will also note to members language in the Registration Statement regarding prospectus delivery requirements for the Shares. The Memo will also reference the fact that there is no regulated source of last sale information regarding physical commodities and that the Commission has no jurisdiction over the trading of physical commodities or the futures contracts on which the value of the shares is based.

2. Statutory Basis

The Exchange believes that the basis under the Act for this proposed rule change is the requirement under section 6(b)(5) ^[35] that an exchange have rules that are designed to prevent fraudulent and manipulative acts and practices, to promote just and equitable principles of trade, to remove impediments to, and perfect the mechanism of a free and open market and, in general, to protect investors and the public interest.

B. Self-Regulatory Organization's Statement on Burden on Competition

The Exchange believes that the proposed rule change would not impose any burden on competition that is not necessary or appropriate in furtherance of the purposes of the Act.

C. Self-Regulatory Organization's Statement on Comments on the Proposed Rule Change Received From Members, Participants or Others

The Exchange has not solicited, and does not intend to solicit, comments on this proposed rule change. The Exchange has not received any written comments from members or other interested parties.

III. Date of Effectiveness of the Proposed Rule

Within 35 days of the date of publication of this notice in the Federal Register or within such longer period (i) as the Commission may designate up to 90 days of such date if it finds such longer period to be appropriate and publishes its reasons for so finding or (ii) as to which the self-regulatory organization consents, the Commission will:

(A) By order approve such proposed rule change; or

(B) Institute proceedings to determine whether the proposed rule change should be disapproved.

The NYSE has requested accelerated approval of the proposed rule change prior to the thirtieth day after the date of publication of notice in the Federal Register, following the conclusion of a 15-day comment period. While the Commission will not grant accelerated approval at this time, the Commission will consider granting accelerated approval of the proposal at the close of the abbreviated comment period of 15 days from the date of publication of the proposal in the Federal Register.

IV. Solicitation of Comments

3.  In Amendment No. 1, the NYSE made some technical and clarifying changes. In addition, the Exchange added Supplementary Material .10 to its proposed Rule 1301B, applying the provisions of its proposed Rules 1300B(b) and 1301B to certain securities listed on the Exchange pursuant to section 703.19 (“Other Securities”) of the NYSE Listed Company Manual, in addition to the securities in this proposal. Specifically, NYSE Rules 1300B(b) and 1301B would apply to securities listed under section 703.19 where the price of such securities is based in whole or part on the price of a commodity or commodities, a commodities index, or any futures contracts or other derivatives based thereon. Examples of the securities to which these securities will apply are the subjects of File No. SR-NYSE-2006-16 (proposal to list and trade Index-Linked Securities of Barclays Bank PLC (“Notes”) linked to the performance of the Dow Jones-AIG Commodity Index Total Return ^TM and File No. SR-NYSE-2006-20 (proposal to list and trade Notes linked to the performance of GSCI Total Return Index).

10.  In the event the Trust utilizes any index that is a successor to or similar to the GSCI-ER or the GSCI Total Return Index, the Exchange will file a proposed rule change pursuant to Rule 19b-4 under the Act. Such filing would address, among other things, the characteristics of the successor or substitute index and the Exchange's surveillance procedures applicable to such index. Unless approved for continued trading, the Exchange would commence delisting proceedings. See “Continued Listing Criteria,” infra. Telephone conference between Michael Cavalier, Assistant General Counsel, NYSE, and Florence Harmon, Senior Special Counsel, Commission, on April 10, 2006 (“April 10 Telephone Conference”).

The Exchange will also file a proposed rule change pursuant to Rule 19b-4 if GSCI substantially changes either the Index component selection methodology or the weighting methodology. In addition, the Exchange will file a proposed rule change pursuant to Rule 19b-4 whenever GSCI adds a new component to the Index using pricing information from a market with which the Exchange does not have a previously existing information sharing agreement or switches to using pricing information from such a market with respect to an existing component when such component constitutes more than 10% of the weight of the Index. Unless approved for continued trading, the Exchange would commence delisting proceedings. See “Continued Listing Criteria,” infra. April 10 Telephone Conference.

11.  “Short-Term Securities” means U.S. Treasury Securities or other short-term securities and similar securities, in each case that are eligible as margin deposits under the rules of the CME.

12.  Trading hours for CERFs on GLOBEX will be as follows: Sunday, 6 p.m. to 2:40 p.m. (next day) (New York time); Monday to Thursday, 6 p.m. to 2:40 p.m. (next day) and 3 p.m. to 5 p.m. (New York time).

13.  Authorized Participants will require access to a commodities account in connection with creation/redemption activity of Shares. April 13 Telephone Conference.

14.  Goldman, Sachs & Co., which is a broker/dealer, calculates the GSCI and GSCI-ER. April 13 Telephone Conference.

15.  See “Calculation of the Index,” infra.

16.  The GSCI is a separate index from the Index; however, the value of the Index (and GSCI-ER index) is derived from the GSCI, as described below. The component selection for the GSCI would obviously affect the Index and the GSCI-ER. April 13 Telephone Conference.

17.  As mentioned above, Goldman, Sachs & Co., a broker-dealer, is the Index Sponsor of the GSCI, the GSCI-ER and the Index, and in that capacity the company calculates those indices. Goldman, Sachs & Co. has represented to the Trust Sponsor that they: (i) Have or will, prior to issuance of the Shares, put in place policies reasonably designed to prevent the use and dissemination by Goldman, Sachs & Co. employees in violation of applicable laws, rules and regulations, of material, non-public information relating to changes in the composition or method of computation or calculation of the Index; and (ii) periodically check the application of such policies as they related to Goldman, Sachs & Co. employees directly responsible for such changes. In addition, the Policy Committee members are subject to written policies with respect to material, non-public information. April 13 Telephone Conference.

18.  Telephone conference between Michael Cavalier, Assistant General Counsel, NYSE, and Florence Harmon, Senior Special Counsel, Commission, on April 14, 2006 (“April 14 Telephone Conference”).

19.  If such actions by the Index Sponsor are implemented on more than a temporary basis, the Exchange will contact the Commission Staff and, as necessary, file a proposed rule change pursuant to Rule 19b-4 seeking Commission approval to continue to trade the Shares. Unless approved for continued trading, the Exchange would commence delisting proceedings. See “Continued Listing Criteria,” infra; April 10 Telephone Conference.

20.  The contract daily return on any given day is equal to the sum, for each of the commodities included in the GSCI, of the applicable daily contract reference price on the relevant contract multiplied by the appropriate CPW and the appropriate “roll weight,” divided by the total dollar weight of the GSCI on the preceding day, minus one.

The “roll weight” of each commodity reflects the fact that the positions in contracts must be liquidated or rolled forward into more distant contract expirations as they near expiration. If actual positions in the relevant markets were rolled forward, the roll would likely need to take place over a period of days. Since the GSCI is designed to replicate the performance of actual investments in the underlying contracts, the rolling process incorporated in the GSCI also takes place over a period of days at the beginning of each month, referred to as the “roll period.” On each day of the roll period, the “roll weights” of the first nearby contract expirations on a particular commodity and the more distant contract expiration into which it is rolled are adjusted, so that the hypothetical position in the contract on the commodity that is included in the GSCI is gradually shifted from the first nearby contract expiration to the more distant contract expiration.

21.  April 10 Telephone Conference.

22.  The price at which the Shares trade should be disciplined by arbitrage opportunities created by the ability to purchase or redeem shares of the Trust in Basket size. This should help ensure that the Shares will not trade at a material discount or premium to their net asset value or redemption value.

23.  The value of a Share may accordingly be influenced by non-concurrent trading hours between the NYSE and the various futures exchanges on which the futures contracts based on the Index commodities are traded. While the Shares will trade on the NYSE from 9:30 a.m. to 4:15 p.m. New York time, the table above lists the trading hours for each of the Index commodities underlying the futures contracts.

29.  See Rule 10A-3(c)(7), 17 CFR 240.10A-3(c)(7) (stating that a listed issuer is not subject to the requirements of Rule 10A-3 if the issuer is organized as a trust or other unincorporated association that does not have a board of directors and the activities of the issuer are limited to passively owning or holding securities or other assets on behalf of or for the benefit of the holders of the listed securities).

See also Securities Exchange Act Release No. 48745 (November 4, 2003), 68 FR 64154 (November 12, 2003) (SR-NYSE-2002-33, SR-NASD-2002-77, et al.) (specifically noting that the corporate governance standards will not apply to, among others, passive business organizations in the form of trusts); Securities Exchange Act Release No. 47654 (April 25, 2003), 68 FR 18787 (April 16, 2003) (noting in Section II(F)(3)(c) that “SROs may exclude from Exchange Act Rule 10A-3's requirements issuers that are organized as trusts or other unincorporated associations that do not have a board of directors or persons acting in a similar capacity and whose activities are limited to passively owning or holding (as well as administering and distributing amounts in respect of) securities, rights, collateral or other assets on behalf of or for the benefit of the holders of the listed securities.”)

30.  In particular, proposed NYSE Rule 1300B provides that NYSE Rule 105(m) is deemed to prohibit an equity specialist, his member organization, other member, allied member or approved person in such member organization or officer or employee thereof from acting as a market maker or functioning in any capacity involving market-making responsibilities in the applicable futures contracts, except as otherwise provided therein.

31.  NYSE Rule 80B.

32.  In such events, the Exchange would immediately contact the Commission to discuss measures that may be appropriate under the circumstances.

33.  As a general matter, the Exchange has regulatory jurisdiction over its member organizations and any person or entity controlling a member organization. The Exchange also has regulatory jurisdiction over a subsidiary or affiliate of a member organization that is in the securities business. A member organization subsidiary or affiliate that does business only in commodities would not be subject to NYSE jurisdiction, but the Exchange could obtain certain information regarding the activities of such subsidiary or affiliate through reciprocal agreements with regulatory organizations of which such subsidiary or affiliate is a member.

34.  The applicable rules are: Rule 10a-1; Rule 200(g) of Regulation SHO; section 11(d)(1) and Rule 11d1-2; and Rules 101 and 102 of Regulation M under the Act.
