Part I

Item 1. Business.

Summary

The iShares® S&P GSCI Commodity-Indexed Trust, or the Trust, is a Delaware statutory trust formed on July 7, 2006. The Trust issues units of beneficial interest, called Shares, representing fractional undivided beneficial interests
in its net assets. Substantially all of the assets of the Trust consist of interests in the iShares® S&P GSCI
Commodity-Indexed Investing Pool LLC, or the Investing Pool. The Investing Pool is a Delaware limited liability company formed on July 7, 2006. The Investing Pool holds long positions in futures contracts on the S&P GSCI Excess Return Index, called CERFs. It is the objective of the Trust that the performance of the Shares will correspond generally to the performance of the S&P GSCI Total Return Index, or the Index, before payment of the Trusts and the Investing Pools expenses and liabilities. The Index is intended to reflect the performance of a diversified
group of commodities.

Barclays Global Investors International, Inc., or BGII, is the Sponsor of the Trust and the Manager of the Investing Pool. Barclays
Global Investors, N.A. is the Trustee of the Trust. The Trust and the Investing Pool are commodity pools, as defined in the Commodity Exchange Act and the applicable regulations of the Commodity Futures Trading Commission, or CFTC, and are operated
by BGII, a commodity pool operator registered with the CFTC. Neither the Trust nor the Investing Pool is an investment company registered under the Investment Company Act of 1940, as amended.

The Trust intends to offer Shares on a continuous basis. The Trust issues and redeems Shares only in one or more blocks of 50,000 Shares called Baskets. These
transactions are generally in exchange for consideration (or redemption proceeds) consisting of CERFs and cash (or, in the discretion of the Sponsor, short-term or similar securities in lieu of cash, referred to as Short-Term Securities)
with a value equal to the net asset value per Basket on the date the creation or redemption order is received. Only certain institutions, called Authorized Participants, that enter into an agreement with the Trust may purchase or redeem Baskets.
Shareholders who are not Authorized Participants have no right to redeem their Shares; they may redeem their Shares only through an Authorized Participant and only in Baskets.

The activities of the Trust are limited to:



| | (1) | issuing Baskets in exchange for CERFs and cash (or, in the discretion of the Sponsor, Short-Term Securities in lieu of cash),
| | --- | -----------------------------------------------------------------------------------------------------------------------------



| | (2) | contributing the proceeds described in (1) that it receives in connection with issuances of Baskets to the Investing Pool in return for interests in the Investing Pool, or
Investing Pool Interests,
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (3) | paying out of Trust assets any Trust expenses and liabilities not assumed by the Sponsor,
| | --- | -----------------------------------------------------------------------------------------



| | (4) | delivering proceeds consisting of CERFs, cash and Short-Term Securities in exchange for Baskets surrendered for redemption, and
| | --- | -------------------------------------------------------------------------------------------------------------------------------



| | (5) | redeeming Investing Pool Interests in exchange for the proceeds described in (4).
| | --- | ---------------------------------------------------------------------------------

The Trust, through the Investing Pool, will be a passive investor in CERFs and the cash or short-term securities posted as margin to collateralize the Investing Pools CERF positions.

The activities of the Investing Pool are limited to:

To the extent that the Investing Pool accepts proceeds from the Trust in the form of cash rather than CERFs and other assets, the Investing Pool will use that cash 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 those CERFs.

Barclays Global Fund Advisors, or the Advisor, which is a commodity trading advisor registered with the CFTC, acts as the commodity trading advisor for the Investing
Pool. The Advisor enters into long positions in CERFs and posts cash and Short-Term Securities as collateral on behalf of the Investing Pool.

Investment Objective of the Trust and the Investing Pool

The investment objective of the Trust is to seek investment results, through the Trusts investment in the Investing Pool, that correspond generally, but are not necessarily identical, to the performance of the
Index, before payment of expenses and liabilities of the Trust and the Investing Pool. The Investing Pool holds long positions in CERFs, which are futures contracts listed on the Chicago Mercantile Exchange, or CME, that have a term of approximately
five years after listing and whose settlement at expiration is based on the value of the S&P GSCI Excess Return Index, or S&P GSCI-ER, at that time.

CERFs are cash-settled futures contracts that settle approximately five years after their initial listing. Each CERF is a contract that provides for cash settlement, at expiration, based upon the final settlement value of the S&P
GSCI-ER at the expiration of the contract, multiplied by a fixed dollar multiplier. Accordingly, a position in CERFs provides the holder with the positive or negative return on the S&P GSCI-ER during the period in which the position is held. For
further discussion of the CERFs, see Futures Contracts on the S&P GSCI-ER below.

The Investing Pool also earns interest on the assets used
to collateralize its holdings of CERFs. The interest on the collateral deposited by the Investing Pool as margin, together with the returns from the CERFs, is expected to result in a total return for the Investing Pool that corresponds generally,
but is not identical, to the Index.

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, any commodities underlying the Index, or any assets posted as margin.

The Shares are intended
to constitute a relatively cost-effective means of achieving investment exposure to the performance of the Index. Although the Shares are not 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.

Secondary
Market Trading

While the Trust anticipates that the price of the Shares will fluctuate in a manner that reflects changes in the Trusts net asset
value over time, at any given time the Shares may trade at, above or below their NAV. The NAV will fluctuate primarily with changes in the market value of CERFs. The trading price of the Shares will fluctuate in accordance with changes in their NAV,
intraday changes in the value of the CERFs and market supply and demand. The amount of the discount or premium in the trading price relative to the NAV may be influenced by non-concurrent trading hours between NYSE Arca on which the Shares trade,
the CME, on which CERFs trade, and the principal commodities markets on which the futures contracts in the S&P GSCI-ER trade. While the Shares are expected to trade on NYSE Arca until 8:00 p.m., New York City time, liquidity in the markets for
the underlying commodities will be reduced whenever the principal markets for these contracts are closed, which usually occurs from 1:40 p.m. to 2:00 p.m. and from 4:00 p.m. to 5:00 p.m., Chicago time, for the CERFs. As a result, trading spreads,
and the resulting premium or discount on the Shares, may widen during these gaps in market trading hours.

Investing Pool Interests will be
issued by the Investing Pool only to the Trust and the Manager. Because Investing Pool Interests, by their terms, may be held only by the Trust and the Manager, there will be no secondary market for Investing Pool Interests.

Valuation of CERFs; Computation of Trusts Net Asset Value

The
Trustee determines the net asset value of the Trust and the net asset value per Share, or NAV, as of 4:15 p.m., New York City time, on each Business Day on which NYSE Arca is open for regular trading, as soon as practicable after that time. The
Trustee values the Trusts assets based upon the determination by the Manager, which may act through the Investing Pool administrator, of the net asset value of the Investing Pool. The Manager determines the net asset value of the Investing
Pool as of the same time that the Trustee determines the net asset value of the Trust.



2



---

##### Table of Contents

The Manager values 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) equals the product of (a) the number of CERF contracts owned by the Investing Pool and (b) 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 uses the most recently announced CME settlement price unless the Manager determines that such 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 on each trading day.

The Manager values
all other property of the Investing Pool at (a) its current market value, if quotations for such property are readily available, or (b) its fair value, as reasonably determined by the Manager, if the current market value cannot be
determined.

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 subtracts 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, then
calculates the value of the Trusts Investing Pool Interests and provides 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 subtracts 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 net asset value of the Trust. The Trustee determines the NAV by dividing the
net asset value of the Trust by the number of Shares outstanding at the time the calculation is made. Shares to be delivered under a creation order are considered to be outstanding for purposes of determining the NAV if the applicable creation order
was received by the Trustee prior to 2:40 p.m., New York City time (or, on any day on which the CME is scheduled to close early, prior to the close of trading of CERFs on the CME on such day), on the date of calculation. Shares to be delivered under
a redemption request are not considered to be outstanding for purposes of calculating the NAV if the applicable redemption request was received by the Trustee prior to 2:40 p.m., New York City time (or, on any day on which the CME is scheduled to
close early, prior to the close of trading of CERFs on the CME on such day), on the date of calculation.

Trust Expenses

The Sponsor is obligated under the Trust Agreement to pay the following administrative, operational and marketing expenses:



| | (1) | the fees of the Trustee, the Delaware Trustee, the Trust administrator and the processing agent,
| | --- | ------------------------------------------------------------------------------------------------



| | (2) | NYSE Arca listing fees,
| | --- | -----------------------



| | (3) | printing and mailing costs,

| | (7) | legal expenses up to $100,000 annually.
| | --- | ---------------------------------------

The Trust is not expected to
have other ordinary recurring administrative, operational or marketing expenses. The Sponsor paid the costs of the Trusts organization and initial sale of Shares.

The Sponsor does not receive a fee in connection with its role as Sponsor. However, BGII receives an allocation in connection with its role as Manager of the Investing Pool that accrues daily at an annualized rate
equal to 0.75% of the net asset value of the Investing Pool and is payable by the Investing Pool monthly in arrears. The Manager earned $5,181,296 for the year ended December 31, 2008.

The Sponsor and the Trustee can amend or terminate the Sponsors obligation to pay certain expenses of the Trust pursuant to the Trust Agreement.

The Trust is responsible for paying any applicable brokerage commissions and similar transaction fees out of its assets. The Sponsor does not expect such commissions and
fees to exceed $10,000 in any year.

The Trustee will also pay the following expenses out of the assets of the Trust:



| |  |  | any expenses of the Trust that are not assumed by the Sponsor;
| | - |  | --------------------------------------------------------------



| |  |  | any taxes and other governmental charges that may fall on the Trust or its property;
| | - |  | ------------------------------------------------------------------------------------



| |  |  | any expenses of any extraordinary services performed by the Trustee or the Sponsor on behalf of the Trust or expense of any action taken by the Trustee or the
Sponsor to protect the Trust and the rights and interests of holders of the Shares; and
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | any indemnification of the Sponsor.
| | - |  | -----------------------------------

##### Table of Contents

The Trustee is also entitled to charge the Trust for all expenses and disbursements incurred by the Trustee in connection
with the actions described in the second and third bullet points above, including fees and disbursements of its legal counsel; provided that the Trustee is not entitled to charge the Trust for (1) expenses and disbursements that were incurred
by it before the Shares were publicly traded and (2) fees of agents for performing services that the Trustee is required under the Trust Agreement to perform.

The Trustee, at the direction of the Sponsor, may liquidate the Trusts property from time to time as necessary to permit payment of the fees and expenses that the Trust is required to pay. The Trustee is not responsible for any
depreciation or loss incurred by reason of the liquidation of Trust property made in compliance with the Trust Agreement.

Creation of Baskets

The Trust intends to offer Shares on a continuous basis on each Business Day, but only in Baskets 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 Sponsor, 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 City 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. The Trustee will notify the Authorized Participants of the Basket Amount on each Business Day.

Before the Trust will issue any Baskets to an Authorized Participant, that Authorized Participant must deliver to the Trustee a 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
below.

Upon the transfer of (1) the required consideration of CERFs and cash (or, in the discretion of the Sponsor, Short-Term Securities in lieu of
cash) in the amounts, and to the accounts, specified by the Trustee, and (2) the Trustees transaction fee per Basket of $6.50 multiplied by the number of CERFs included in the Basket Amount, the Trustee will deliver the appropriate number
of Baskets to the DTC account of the Authorized Participant. In limited circumstances and with the approval of the Sponsor, 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.

No Shares will be issued unless and until the
Trustee receives confirmation that (1) the required consideration has been received in the account or accounts specified by the Trustee and (2) 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 following the Business Day on which the creation order is
received by the Trustee, which is referred to as a T+1 settlement cycle. If the Trustee has not received the required consideration for the Shares to be delivered on the delivery date, by 11:00 a.m., New York City time, the Trustee may cancel the
creation order.

The Trustee has the absolute right to reject any creation order, including, without limitation, (1) creation orders that the Trustee
has determined are not in proper form, (2) creation orders that the Trustee has determined would have adverse tax or other consequences to the Trust, the Investing Pool or the Shareholders, or (3) creation orders the acceptance of which
would, in the opinion of counsel to the Trustee or the Sponsor, result in a violation of law. Neither the Trustee nor any agents acting on its behalf will be liable to any person for rejecting a creation order.

Redemption of Baskets

Authorized Participants may typically surrender Baskets in exchange only for an amount of CERFs and cash (or, in the discretion of the Sponsor, 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 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 below.

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 Sponsor, 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 equal to $6.50 multiplied by the number of CERFs included in the Basket Amount. In limited circumstances and with the approval of the Trustee, Baskets may be redeemed for cash, in which case the
Authorized Participant 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.

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 11:00 a.m., New York City time, on the delivery date, the Trustee may cancel the redemption order.

The Trustee has the absolute right to reject any redemption order, including, without limitation, (1) redemption orders that the Trustee has determined are not in
proper form, (2) redemption orders the acceptance of which would, in the opinion of counsel to the Trustee or the Sponsor, result in a violation of law, or (3) during any period in which circumstances make transactions in, or settlement or
delivery of, CERFs impossible or impractical. Neither the Trustee nor any agents acting on its behalf will be liable to any person for rejecting a redemption order.

Custody of the Trust Assets

The creation and redemption of Baskets, and the corresponding creation and redemption of
Investing Pool Interests, will generally be effected through transactions known as exchange of futures for physicals, or EFPs. Because EFPs involve contemporaneous transfers, it is anticipated that the Trust will not hold CERFs and the
securities used to collateralize CERFs on a regular basis. The Investing Pool Interests, which are not certificated, will be recorded in the books and records of the Trust by the Trustee and in the books and records of the Investing Pool by the
Manager. To the extent the Trust has property that requires a custodian, the Trustee will appoint an agent qualified to maintain the property of the Trust.

Investing Pool Agreement

The Investing Pool is governed by the Investing Pool Agreement, entered into between the Trust and BGII, as
members. BGII serves as Manager under the Investing Pool Agreement and, as such, is responsible for the administration of the Investing Pool.

The
Investing Pool issues Investing Pool Interests only to the Trust and the Manager, and neither the Trust nor the Manager may transfer Investing Pool Interests to any other person; provided that the Manager may transfer its Investing Pool Interests to
any non-natural person that is an affiliate of the Manager. Each time Shares are created or redeemed, the Trust will contribute to the Investing Pool, or receive a distribution from the Investing Pool, in an amount equivalent to the Basket Amount it
receives in connection with such creation or redemption. The Manager made an initial contribution of $25,000 to the Investing Pool.

##### Table of Contents

The Manager has delegated some of the administration of the Investing Pool to Barclays Global Investors, N.A., the
Administrator, which in turn has employed State Street Bank and Trust Company as the Investing Pool administrator to maintain various records and carry out various duties on behalf of the Investing Pool. Barclays Global Investors, N.A. has also
employed PricewaterhouseCoopers LLP as the Tax Administrator to provide tax accounting and tax reporting services for the Trust and the Investing Pool.

The Manager will pay expenses that would otherwise be considered ordinary operating expenses of the Investing Pool (other than trading commissions). In recognition of its paying these expenses, as well as the ordinary operating expenses
with respect to the Trust, for which Barclays Global Investors International, Inc. serves as Sponsor, the Manager receives a special allocation from the Investing Pool that accrues daily at an annualized rate equal to 0.75% of the net asset value of
the Investing Pool and is payable by the Investing Pool monthly in arrears.

The Investing Pool has entered into a commodity trading advisor agreement with
the Advisor, which provides the Advisor with discretionary authority to make all determinations with respect to the Investing Pools assets, subject to specified limitations. The Investing Pool has also entered into a futures commission
merchant agreement that provides for the execution and clearing of transactions in futures, payment of commissions, custody of assets and other standard provisions. Goldman, Sachs & Co. is the Clearing FCM of the Investing Pool. The
Investing Pool may employ other futures commission merchants for the execution of CERF transactions.

Goldman, Sachs & Co. and some of its affiliates trade the contracts comprising the S&P GSCI, as well as the underlying commodities and other derivative instruments
thereon, for their proprietary accounts and other accounts under their management. Goldman, Sachs & Co. and some of its affiliates may underwrite or issue other securities or financial instruments indexed to the S&P GSCI and related indices. These activities could present conflicts of interest and could adversely affect the value of the S&P GSCI. There may be conflicts of interest between you and Goldman, Sachs & Co. See Risk FactorsRisk Factors Relating to Conflicts of Interest Proprietary trading and other activities by Goldman,
Sachs & Co. and its affiliates could conflict with your interests as a Shareholder.

Neither the Manager nor the Trust or any of their
respective agents or officers will have personal liability to the Investing Pool or the other for monetary damages for breach of fiduciary duty (if any) or any act or omission performed or omitted by any such person in good faith on behalf of the
Investing Pool, except for such persons gross negligence or willful misconduct. The Investing Pool Agreement provides that, to the extent it has available assets, the Investing Pool will indemnify the Trust, the Manager and the officers,
agents and delegates of the Investing Pool, for any loss, damage, claim or expense based on their conduct relating to the Investing Pool, provided that the conduct resulting in the loss, damage, claim or expense did not result from the indemnified
parties gross negligence, bad faith or willful misconduct.

Futures Contracts on the S&P GSCI-ER

The assets of the Investing Pool consist of CERFs and cash or Short-Term Securities posted as margin to
collateralize the Investing Pools CERF positions. CERFs are traded on the CME and were first listed and made available for trading on March 13, 2006. Consequently, CERFs have a limited trading history. Futures contracts and options on
futures contracts on the S&P GSCI, which does not reflect the excess return embedded in the S&P GSCI-ER , have been traded on the CME since 1992. CERFs are listed and traded
separately from the S&P GSCI futures contracts and options on futures contracts.

CERFs
are subject to the rules of the CME. CERFs trade on GLOBEX, the CMEs electronic trading system, and do not trade through open outcry on the floor of the CME. Transactions in CERFs are cleared through the CME clearing house by the traders
futures commission merchant acting as its agent. Under these clearing arrangements, the CME clearing house becomes the buyer to each member futures commission merchant representing a seller of the contract and the seller to each member futures
commission merchant 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 futures commission merchant carrying its
position in CERFs.

CERFs are cash settled futures contracts that settle approximately five years after initial listing. Each CERF is a contract that
provides for cash settlement, at expiration, based upon the final settlement value of the S&P GSCI-ER at the expiration of the contract, multiplied by a fixed dollar multiplier. On a daily basis, most market participants with positions in CERFs
are



6



---

##### Table of Contents

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 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 7%. Certain market participants, known as 100% margin participants, however, are required to deposit with their futures commission merchant initial
margin in an amount equal to 100% of the value of the CERF on the date the position is established. The futures commission merchant, in turn, is required to deliver to the CME clearing house initial margin at a level generally expected to be from 3%
to 7% and pledge to the clearing house, pursuant to a separate custody arrangement pursuant to CME rules, an amount equal to the remainder of the 100% margin amount posted by 100% margin participants. The separate custody arrangement will be an
account with the FCM.

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

If the daily settlement price increases, the futures commission merchant receives variation margin from the clearinghouse for the account of the 100% margin participant,
which it holds in the separate custody account for the benefit of the 100% margin participant. The buyer is not, however, entitled to receive or withdraw this variation margin from its futures commission merchant until the liquidation or final
settlement of its CERF position. The buyer is 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 futures commission merchant its initial margin deposit, adjusted for variation
margin paid or received by the futures commission merchant 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 futures commission merchant).

The 100% margin participants include any market participant that is
(1) an investment company registered under the Investment Company Act or (2) 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, 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 is a 100% margin participant. The Investing Pool satisfies 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.

CERFs also 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. 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, are generally 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 the context of CERFs, the CME permits the execution of EFPs consisting of simultaneous purchases (sales) of CERFs and sales (purchases) of Shares. This
mechanism generally is used by the Trust in connection with the creation and redemption of Baskets. Specifically, it is anticipated that an Authorized Participant requesting the creation of additional Baskets typically will transfer



7

##### Table of Contents

CERFs and cash (or, in the discretion of the Sponsor, Short-Term Securities in lieu of cash) to the Trust in return for Shares. The Trust will simultaneously
contribute to the Investing Pool the CERFs (and any cash or Short-Term Securities) received from an 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 an Authorized
Participant CERFs, cash or Short-Term Securities. In order to obtain the CERFs and cash or Short-Term Securities to be transferred to an Authorized Participant, the Trust will redeem an equivalent portion of its interest in the Investing Pool
Interests.

Trustee, the Delaware Trustee, the Trust or the Investing Pool accepts any responsibility for the calculation, maintenance or publication of, or for any error, omission or disruption in, the Index or the S&P GSCI-ER.

The Index and the S&P GSCI-ER were established in May 1991. The Index reflects the value of an investment in the S&P GSCI-ER together with a Treasury bill
return. The S&P GSCI-ER reflects the returns that are potentially available through a rolling uncollateralized investment in the contracts comprising the S&P 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 S&P GSCI-ER is designed to reflect the return from rolling each contract included in the S&P GSCI as it nears expiration into the
next available delivery month. 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.

More specifically, the rolling of the
contracts included in the S&P GSCI occurs on the fifth through the ninth business days of each month. During this roll period, each contract is shifted from the contract with the nearest expiration to the contract with the next nearest
expiration at a rate of 20% per day for each the five days of the roll period. Therefore, during the first four business days of a month, and just before the end of the fifth business day, the S&P GSCI consists of futures contracts
with the nearest expirations. The S&P GSCI is calculated as though each contract roll occurs at the end of each day during the roll period, at the daily settlement prices. At the end of the fifth business day, the S&P GSCI is
adjusted so that 20% of the contracts underlying the S&P GSCI held are in the next nearest expiring contracts, with 80% remaining in the nearest expiring contracts. The roll process continues on the sixth, seventh and eighth business days,
with the relative weights of the nearest to the next nearest expirations gradually shifting from a 60%/40% weighting, to a 40%/60% weighting, to a 20%/80% weighting. At the end of the ninth business day, the last of the contracts with the nearest
expirations are exchanged, completing the roll and leaving the S&P GSCI composed entirely of contracts with the next nearest expirations. SeeContract Daily Return.

The S&P GSCI itself is an index on a production-weighted basket of principal physical commodities that satisfy specified criteria. The S&P 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 S&P 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 S&P GSCI are weighted, on a production basis, to reflect the relative significance (in the view of the Index
Sponsor) of those commodities to the world economy. The fluctuations in the level of the S&P GSCI are intended generally to correlate with changes in the prices of those physical commodities in global markets. The value of the S&P
GSCI has been normalized such that its hypothetical level on January 2, 1970 was 100.

The following is a summary of the composition of and the
methodology used to calculate the S&P GSCI as of the date of this annual report. The methodology for determining the composition and weighting of the S&P GSCI and for calculating its value is subject to modification in a manner
consistent with the purposes of the S&P GSCI, as described below. The Index Sponsor makes the official calculations of the value of the S&P GSCI. At present, this calculation is performed continuously and is reported on Reuters
Page. SPGSCI and on Bloomberg page SPGSCI<index> and is updated at least once every three minutes during business hours on each day on which the S&P GSCI is calculated, referred to as an S&P GSCI Business Day.
The settlement price for the S&P GSCI-ER is reported on Reuters Page. SPGSCIP and on Bloomberg page SPGSCIP<index> at the end of each S&P GSCI Business Day. If Reuters ceases to publish the value of the S&P GSCI or the
settlement price of the S&P GSCI-ER, the Index Sponsor has undertaken to use commercially reasonable efforts to ensure that a comparable reporting service publishes the value of the S&P GSCI and the settlement price of the S&P
GSCI-ER so long as any Shares are outstanding.

In light of the rapid development of electronic trading platforms and the potential for significant shifts
in liquidity between traditional exchanges and those platforms, the Index Sponsor may review both the procedures and criteria for determining the contracts to be included in the S&P GSCI, as well as the procedures and criteria for
evaluating available liquidity on an intra-year basis in order to provide S&P GSCI market participants with efficient access to new sources of liquidity and the potential for more efficient trading. In particular, the Index Sponsor may
examine the conditions under which an instrument traded on an electronic platform, rather than a traditional futures contract traded on a traditional futures exchange, should be permitted to be included in the S&P GSCI and how the
composition of the S&P GSCI should respond to rapid shifts in liquidity between those instruments and contracts currently included in the S&P GSCI.

The Index Committee and Index Advisory Panel

The Index Sponsor has established an Index Committee to oversee the daily management and operations of the S&P GSCI, and is responsible for all analytical methods and calculation in the indices. The Index
Committee is comprised of three full-time professional members of S&Ps staff and two members of Goldman Sachs Group. At each meeting, the Index Committee reviews any issues that may affect index constituents, statistics comparing the
composition of the indices to the market, commodities that are being considered as candidates for addition to an index, and any significant market events. In addition, the Index Committee may revise index policy covering rules for selecting
commodities, or other matters.

S&P considers information about changes to its indices and related matters to be potentially market moving and
material. Therefore, all Index Committee discussions are confidential.

In addition, the Index Sponsor has established an Index Advisory Panel to assist it
with the operation of the S&P GSCI. The Index Advisory Panel meets on an annual basis and at other times at the request of the Index Committee. The principal purpose of the Index Advisory Panel is to advise the Index Committee with respect
to, among other things, the calculation of the S&P GSCI, the effectiveness of the S&P GSCI as a measure of commodity futures market performance and the need for changes in the composition or the methodology of the S&P
GSCI. The Index Advisory Panel acts solely in an advisory and consultative capacity. The Index Committee makes all decisions with respect to the composition, calculation and operation of the S&P GSCI.

Composition of the S&P GSCI

In order to be included in the
S&P GSCI, a contract must satisfy the following eligibility criteria:



|1) | 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;
| | -- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 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; and
| | -- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | d) | be traded on a trading facility that allows market participants to execute spread transactions, through a single order entry, between the pairs of contract expirations included in
the S&P GSCI that at any given point in time will be involved in the rolls to be effected in the next three roll periods.
| | -- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|2) | 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:
| | -- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | i) | 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;
| | -- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ii) | 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;
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | iii) | accepts bids and offers from multiple participants or price providers; and
| | ---- | --------------------------------------------------------------------------



| | iv) | is accessible by a sufficiently broad range of participants.
| | --- | ------------------------------------------------------------



|3) | 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 S&P GSCI. In appropriate circumstances, however, the Index Sponsor, in consultation with the Index 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.

|4) | At and after the time a contract is included in the S&P GSCI, the daily contract reference price for that contract must be published between 10:00 a.m. and 4:00 p.m., New
York City 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.
|-- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|5) | 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.
|-- | -----------------------------------------------------------------------------------------------------------------------------------------------------------



|6) | A contract that is not included in the S&P GSCI at the time of determination and that is based on a commodity that is not represented in the S&P GSCI at that
time must, in order to be added to the S&P GSCI at that time, have an annualized total dollar value traded over the relevant period 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 and any related 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.
|-- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|7) | A contract that is already included in the S&P GSCI at the time of determination and that is the only contract on the relevant commodity included in the S&P GSCI
must, in order to continue to be included in the S&P GSCI after that time, have an annualized total dollar value traded over the relevant period 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.
|-- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|8) | A contract that is not included in the S&P 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 S&P GSCI at that time must, in order to be added to the S&P GSCI at that time, have an annualized total dollar value traded over the relevant period of at least $30 billion.
|-- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|9) | A contract that is already included in the S&P 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 S&P GSCI at that time must, in order to continue to be included in the S&P GSCI after that time, have an annualized total dollar value traded over the relevant period 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.
|-- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|10) | A contract that is:
|--- | -------------------



| | a) | already included in the S&P 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 S&P GSCI 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 S&P
GSCI and each contracts percentage of the total is then determined. The CPW of a contract is its weight in the S&P GSCI.
| | -- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | b) | not included in the S&P GSCI at the time of determination must, in order to be added to the S&P GSCI at that time, have a reference percentage dollar weight of
at least 1.00%.
| | -- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|11) | In the event that two or more contracts on the same commodity satisfy the eligibility criteria:
|--- | -----------------------------------------------------------------------------------------------



| | a) | Such contracts will be included in the S&P 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
S&P 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 S&P 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 portions of the S&P GSCI attributable to all commodities are 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 S&P GSCI attributable to it.

The quantity of each of the contracts included in the S&P 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 the Index 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 S&P 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 S&P 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 S&P GSCI is reevaluated, based on the criteria and weighting procedure described above. This procedure is undertaken to allow the S&P 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 S&P 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 (1) a substantial



13



---

##### Table of Contents

shift of liquidity away from a contract included in the Index as described above, or (2) 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 publish the nature of the changes, through websites, 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 S&P GSCI at the conclusion of each year, based on the above criteria. Other commodities that satisfy that criteria, if any, will be added to the S&P GSCI.
Commodities included in the S&P GSCI that no longer satisfy that criteria, if any, will be deleted.

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

Contract Expirations

Because the S&P GSCI is comprised of actively traded contracts with scheduled expirations, it can be calculated only by reference to the prices of contracts for specified expiration, delivery or settlement periods, referred to as
contract expirations. The contract expirations included in the S&P GSCI for each commodity during a given year are designated by the Index Sponsor, in consultation with
the Index Committee, provided that each contract must be an active contract. An active contract for this purpose is a liquid, actively-traded contract expiration, as defined or identified by the relevant trading facility or,
if no such definition or identification is provided by the relevant trading facility, as defined by standard custom and practice in the industry.

If a trading facility deletes one or more contract expirations, the S&P GSCI will be calculated during the remainder of the year in which that deletion occurs on the basis of the remaining contract expirations designated by the Index Sponsor. If a trading facility ceases trading in all
contract expirations relating to a particular contract, the Index Sponsor may designate a replacement contract on the commodity. The replacement contract must satisfy the eligibility criteria for inclusion in the S&P GSCI. To the extent practicable, the replacement will be effected during the next monthly review of the composition of the S&P GSCI. If that timing is not practicable, the Index Sponsor will determine the date of the replacement and will consider a number of factors, including the differences between the existing contract and the replacement
contract with respect to contractual specifications and contract expirations.

If a trading facility eliminates one or more contract expirations, but there
are remaining contract expirations of the same contract, the weighting of the commodity underlying the relevant contract will not be affected. If the trading facility ceases trading in all contract expirations relating to a particular contract, and
the Index Sponsor designates a replacement contract on the same commodity, the index weighting allocated to the terminated contract will be allocated to the replacement contract. Accordingly, unless a contract is eliminated entirely and no
replacement contract is designated, a cessation of trading in certain contract expirations or the elimination of a contract will not affect the weighting of commodities in the Index. If a contract is eliminated and there is no replacement contract,
the underlying commodity will necessarily drop out of the Index and the weighting allocated to that contract will then be allocated pro rata to the remaining contracts in the Index. The designation of a replacement contract, or the elimination of a
commodity from the Index because of the absence of a replacement contract, could affect the value of the Index and the S&P GSCI-ER, either positively or negatively, depending on the price of the contract that is eliminated and the prices of the
remaining contracts in the Index. It is impossible, however, to predict the effect of these changes, if they occur, on the value of the Index or the S&P GSCI-ER.

Total Dollar Weight of the S&P GSCI

The total dollar weight of the S&P 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).
| | - |  | -----------------------------------------------------------------------

##### Table of Contents

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 4:00 p.m., New York City 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 S&P GSCI calculation.

It is generally considered unlikely that a trading facility will fail to publish a daily contract reference price in the regular course of business, because the price is
required to margin open positions in the relevant contracts. It is possible, however, that a trading facility will fail to publish a daily contract reference price under emergency or extraordinary conditions, such as in the event of a natural
disaster, act of war or terrorist attack, that prevent trading or cause a termination of trading on a given day. A manifest error in a daily contract reference price is also unlikely to occur, but is nevertheless possible. This could arise, for
example, in the event of a system malfunction that results in the published daily contract reference price being outside the range of trading for the relevant day. In that instance, it would be clear that the published price could not be correct and
the Index Sponsor would likely disregard that price.

Contract Daily Return

The contract daily return on any given day is equal to (1)(A) the sum, for each of the commodities included in the S&P GSCI, of the applicable daily contract reference price on the relevant contract
multiplied by the appropriate CPW and the appropriate roll weight, divided by (B) the total dollar weight of the S&P GSCI on the preceding day, minus (2) 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 S&P GSCI is designed to replicate the performance of actual
investments in the underlying contracts, the rolling process incorporated in the S&P 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 S&P GSCI is gradually shifted from the first nearby contract expiration to the more distant contract expiration.

If on any day
during a roll period any of the following conditions exists, the portion of the roll that would have taken place on that day is deferred until the next day on which these conditions do not exist:



| |  |  | no daily contract reference price is available for a given contract expiration;
| | - |  | -------------------------------------------------------------------------------



| |  |  | any such price represents the maximum or minimum price for that contract month, based on exchange price limits, referred to as a Limit Price;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the daily contract reference price published by the relevant trading facility reflects manifest error, or that price is not published by 4:00 p.m., New York City
time. In that event, the Index Sponsor may, but is not required to, determine a daily contract reference price and complete the relevant portion of the roll based on that price; provided, that, if the trading facility publishes a price before the
opening of trading on the next day, the Index Sponsor will revise the portion of the roll accordingly; or
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | trading in the relevant contract terminates prior to its scheduled closing time.
| | - |  | --------------------------------------------------------------------------------

If any of these conditions exist throughout the roll period, the roll with respect to the affected contract will be affected in its entirety on the next day on which these conditions no longer exist.

Calculation of the S&P GSCI-ER

The value of the S&P GSCI-ER
on any S&P GSCI Business Day is equal to the product of (1) the value of the S&P GSCI-ER on the immediately preceding S&P GSCI Business Day multiplied by (2) one plus the contract daily return on the S&P
GSCI Business Day on which the calculation is made.

Calculation of the Index

The value of the Index on any S&P GSCI Business Day is equal to the product of (1) the value of the Index on the immediately preceding S&P GSCI Business Day multiplied by (2) one plus the sum of the contract
daily return and the Treasury bill return on the S&P GSCI Business Day on which the calculation is made, multiplied by (3) one plus the Treasury bill return for each non- S&P GSCI Business Day since the immediately preceding
S&P GSCI Business Day. The Treasury bill return is the return on a hypothetical investment at a rate equal to the interest rate on a specified U.S. Treasury bill.

Item 1A. Risk Factors.

Risk Factors Relating to Commodities Markets

The value of the Shares depends on the value of CERFs, which will fluctuate based on the prices of commodity futures contracts reflected in the S&P GSCI-ER.
These prices may be volatile, thereby creating the potential for losses, regardless of the length of time you intend to hold your Shares.

Because the
price of the Shares depends on the value of the CERFs held by the Investing Pool, the value of the Shares will fluctuate based on the prices of commodity futures contracts reflected in the S&P GSCI-ER. The value of the S&P GSCI-ER has been
extremely volatile at times during the past several years. Some commodity prices reflected in the S&P GSCI-ER have been at historically high levels and there is no certainty that those prices will remain at those high levels. If they do not, the
level of the S&P GSCI-ER, and consequently the value of the Shares, may be adversely affected. Commodity prices are generally affected by, among other factors, the cost of producing commodities, changes in consumer demand for commodities, the
hedging and trading strategies of producers and consumers of commodities, speculative trading in commodities by commodity pools and other market participants, disruptions in commodity supply, weather, political and other global events and global
economic factors. These factors cannot be controlled by the Trust or the Investing Pool. Accordingly, the price of the Shares could change substantially and in a rapid and unpredictable manner. This exposes you to a potential loss if you need to
sell your Shares when the value of the CERFs is lower than it was when you made your investment. These fluctuations can affect your investment regardless of the length of time you intend to hold your Shares.

The following events, among others, would generally result in a decline in the price of the Shares:



| |  |  | A significant increase in hedging activity by producers of the underlying commodities. Should producers of the S&P GSCI underlying commodities increase
their hedging of their future production through forward sales or other short positions, this increased selling pressure could depress the price of one or more of the underlying commodities, which could adversely affect the price of the Shares.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | A significant change in the attitude of speculators and investors toward the S&P GSCI underlying commodities. Should the speculative community take a
negative view towards one or more of the underlying commodities, it could cause a decline in the CERFs, which may reduce the price of the Shares.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Conversely, several factors may trigger a temporary increase in the price of the S&P GSCI underlying commodities and, consequently, the CERFs. In that case, you could buy Shares at prices affected by the temporarily high commodity
prices, and you could subsequently incur losses when the causes for the temporary increase disappear.

Historical performance of the Index and the
S&P GSCI-ER is no guide to their future performance or to the performance of the Shares.

Past performance of the Index and the S&P GSCI-ER is
not necessarily indicative of their future performance over the life of the Shares or of the performance of the Shares. There can be no guarantee that the level of the Index or the S&P GSCI-ER will increase. You may lose some or all of your
investment in the Shares.

Commodity futures trading may be illiquid. In addition, suspensions or disruptions of market trading in the commodities
markets and related futures markets may adversely affect the value of your Shares.

The commodity futures markets are subject to temporary distortions
or other disruptions due to various factors, including the lack of liquidity, congestion, disorderly markets, limitations on deliverable supplies, the participation of speculators,

government regulation and intervention, technical and operational or system failures, nuclear accidents, terrorism, riots and acts of God. In addition, U.S.
futures exchanges and some foreign exchanges have regulations that limit the amount of fluctuation in futures contract prices that may occur during a single business day. These limits are generally referred to as daily price fluctuation
limits, and the maximum or minimum price of a contract on any given day as a result of these limits is referred to as a limit price. Once the limit price has been reached in a particular contract, it is possible that no trades may
be made at a different price. It is not certain how long any such price limits would remain in effect. Limit prices may have the effect of precluding trading in a particular contract or forcing the liquidation of contracts at disadvantageous times
or prices, consequently affecting the value of the S&P GSCI-ER. These circumstances could thereby adversely affect the value of the CERFs held by the Investing Pool and, therefore, the value of your Shares. In addition, these circumstances could
also limit trading in the CERFs, which could affect the calculation of the NAV and the trading price of the Shares. Accordingly, these limits may result in a NAV that differs, and may differ significantly, from the NAV that would prevail in the
absence of such limits. If Baskets are created or redeemed at a time when these price limits are in effect, the creation or redemption price will reflect the price limits as well.

In calculating the S&P GSCI-ER, if the relevant trading facility does not publish a settlement price as scheduled, or publishes a settlement price that, in the reasonable judgment of the Index Sponsor, is
manifestly incorrect, the Index Sponsor may determine the settlement price in its reasonable judgment. In addition, if any day on which the Index Sponsor calculates the S&P GSCI-ER is a day on which a relevant trading facility for a contract on
a commodity that underlies the S&P GSCI-ER is not open, then the Index Sponsor will use the settlement price for that contract as of the last day on which that trading facility was open. In these circumstances, the value of the CERFs and the
value of your Shares may be adversely affected.

During a period when commodity prices are fairly stationary, an absence of backwardation in
the prices of the commodities included in the S&P GSCI-ER may itself cause the price of your Shares to decrease.

As the futures contracts that
underlie the S&P GSCI-ER near expiration, they are replaced by contracts that have a later expiration. Thus, for example, a contract purchased in September 2008 may specify a December 2008 expiration. As that contract nears expiration, it may be
replaced by selling the December 2008 contract and purchasing the contract expiring in March 2009. This process is referred to as rolling. Historically, the prices of some futures contracts (generally those relating to commodities that
are typically consumed immediately rather than stored) have frequently been higher for contracts with shorter-term expirations than for contracts with longer-term expirations, which is referred to as backwardation. In these
circumstances, absent other factors, the sale of the December 2008 contract would take place at a price that is higher than the price at which the March 2009 contract is purchased, thereby allowing the contract holder to purchase a greater quantity
of the March 2009 contract. While many of the contracts included in the S&P GSCI-ER have historically exhibited consistent periods of backwardation, backwardation will likely not exist at all times. Moreover, some of the commodities reflected in
the S&P GSCI-ER historically exhibit contango markets rather than backwardation. Contango markets are those in which the prices of contracts are higher in the distant delivery months than in the nearer delivery months due to the
costs of long-term storage of a physical commodity prior to delivery or other factors. The forward price of a commodity may also fluctuate between backwardation and contango.

The absence of backwardation, or the existence of contango, in the commodity markets could result in losses, which could adversely affect the value of the S&P GSCI-ER and, accordingly, decrease the value of your
Shares.

Regulatory developments with respect to the futures and over-the-counter markets, and in particular, with respect to speculative trading in
futures contracts and over-the-counter derivatives involving commodities and commodity indices, could adversely affect the value of your Shares.

A
number of bills have been introduced in Congress in response to high energy and commodity prices. These bills generally target perceived excessive speculation in commodities and commodity indices, including by institutional index funds,
on regulated futures markets, unregulated futures markets and in the over-the-counter derivatives markets. These bills include a broad range of measures intended to limit speculation, including possible increases in the margin levels required for
regulated futures contracts; imposing, or tightening existing, speculative position limits applicable to regulated and unregulated futures and over-the-counter derivatives positions; eliminating or narrowing existing exemptions from speculative
position limits; restricting the access of certain classes of investors to futures markets and over-the-counter derivatives markets; and imposing additional reporting requirements on market participants, such as the Investing Pool. If adopted,
certain of these measures could increase the costs of the Investing Pool, could result in significant direct limitations on the maximum permitted size of the Investing Pools futures positions and therefore on the size of the Trust; and could
reduce liquidity in the market for the CERFs and the Shares. It is not possible to predict whether any of these proposed measures, or other adverse measures, will be adopted or precisely how they will ultimately affect the value of your Shares.

Risk Factors Relating to CERFs and the S&P GSCI-ER

The trading of CERFs - the sole contract traded by the Investing Pool - presents risks unrelated to the S&P GSCI-ER that could adversely affect the value of your
Shares.

Substantially all of the assets of the Investing Pool will be allocated to the trading of CERFs, and the Investing Pool will not trade any
other futures contracts. CERFs have a limited trading history. There can be no assurance as to the size or liquidity of the market for CERFs. Illiquidity of the market for CERFs may adversely affect the price of CERFs, the Trusts ability to
track the Index and the Trusts ability to create or redeem Shares. There can be no assurance that the Clearing FCM, any Authorized Participants or any other market participant will make a market or otherwise trade in CERFs at any time or
continue to do so. Withdrawal from the market of any participants, or reduced participation by those persons (particularly where there is only a single participant or a small number of participants), may reduce the liquidity of CERFs and,
accordingly, adversely affect the Shareholders. These risks may be heightened if the Investing Pools CERF positions represent a substantial portion of the long-side open interest in the CERFs. The approximately five-year duration of the CERFs
is also not traditional for futures contracts and may affect their liquidity and trading dynamics, which may in turn adversely affect the Shares. In particular, the rolling of the CERF, as it approaches expiration, could exacerbate any adverse
impacts of illiquidity in the market.

Although CERFs are based on the S&P GSCI-ER, and the value of CERFs should generally track the level of the
S&P GSCI-ER, it is possible that the value of CERFs could be affected by factors that do not directly affect the S&P GSCI-ER. Accordingly, the value of the CERFs and the level of the S&P GSCI-ER will not be precisely correlated at all
times, although arbitrage by market participants is expected to limit any divergence. Nonetheless, the activities of market participants in trading CERFs, or in trading other instruments indexed to the S&P GSCI-ER, could affect the value of the
CERFs independent of any change in the S&P GSCI-ER and adversely affect the correlation between the value of the CERFs and the level of the S&P GSCI-ER. The price of the CERFs will reflect supply and demand in the market for CERFs, which in
turn may reflect market expectations at any given time about prospective changes in the level of the S&P GSCI-ER and other market conditions. In this way, trading in the CERF market might cause a divergence between the CERF price and the level
of the S&P GSCI-ER. Similarly, actions by the CME with respect to CERFs, such as the imposition of trading or price limits, could adversely affect this correlation. In that event, it is possible that changes in the NAV, which is calculated based
on the value of the CERFs, will not adequately reflect changes in the level of the S&P GSCI-ER. In the event of market disruptions with respect to the CERFs, such as a suspension of trading by the CME as a result of market activity, systems or
communications failures or other causes, the value of the CERFs and the level of the S&P GSCI-ER could diverge, which could adversely affect the value of the Shares.

In addition, because CERFs are cleared through the CME clearing house, and the Investing Pools CERF positions are carried on its behalf by the Clearing FCM, the Investing Pool, and therefore the Trust, will be
subject to the risk of a default by the CME clearing house or the Clearing FCM. In that event, the Investing Pool, and therefore the Trust, could be unable to recover amounts due to it on its CERF positions, including assets posted as margin, and
could sustain substantial losses, even if the level of the S&P GSCI-ER increases. The magnitude of the losses may be significantly increased by the requirement to post 100% margin.

The impact of the foregoing considerations may be heightened because of the concentration of the Investing Pools assets in CERFs. The Investing Pool will not be able to avoid these risks by diversifying into
other assets or contracts.

The S&P GSCI-ER may in the future include contracts that are not traded on regulated futures exchanges and that offer
different or diminished protections to investors.

The S&P GSCI-ER is comprised exclusively of futures contracts traded on regulated futures
exchanges. Such exchanges in the United States are referred to as designated contract markets. As described above under The Index and the S&P GSCI-ER, however, the S&P GSCI-ER may in the future include contracts (such
as swaps and forward contracts) traded in the over-the-counter market or on trading facilities that are subject to lesser degrees of regulation or, in some cases, no substantive regulation. As a result, trading in such contracts, and the manner in
which prices and volumes are reported by the relevant trading facilities, may not be subject to the same provisions of, and the protections afforded by, the CEA or other applicable statutes and related regulations that govern trading on regulated
futures exchanges. In addition, many electronic trading facilities have only recently initiated trading and do not have significant trading histories. As a result, the trading of contracts on such facilities and the inclusion of such contracts in
the S&P GSCI-ER may be subject to risks not presented by most exchange-traded futures contracts, including risks related to the liquidity and price histories of the relevant contracts.

Changes in the composition and valuation of the S&P GSCI-ER may adversely affect your Shares.

The composition of the S&P GSCI-ER may change over time as additional commodities satisfy the eligibility criteria or commodities currently included in the S&P
GSCI-ER fail to satisfy those criteria. The weighting factors applied to each commodity included in the S&P GSCI-ER change annually, based on changes in commodity production statistics. In addition, the Index Sponsor may modify the method for
determining the composition and weighting of the S&P GSCI-ER and for calculating its value in order to ensure that the S&P GSCI-ER represents a measure of the performance over time of the markets for the underlying commodities. A number of
modifications to the methodology for determining the contracts to be included in the S&P GSCI-ER, and for valuing the S&P GSCI-ER, have been made in the past several years, and further modifications may be made. Such changes could adversely
affect the value of your Shares. For more information about the methodology for determining the composition and weighting of the S&P GSCI-ER, see The Index and the S&P GSCI-ER.

Ownership of the S&P GSCI indexes changed.

Goldman,
Sachs & Co., the previous Index Sponsor, sold its interest in the GSCI family of indexes, including the S&P GSCI, the S&P GSCI-ER and the Index, to S&P. Upon completion of this sale in May 2007, S&P became the Index
Sponsor. There can be no assurance that S&P, the new Index Sponsor, will not change the determination or valuation methodology of the S&P GSCI, the S&P GSCI-ER or the Index in a manner that may be adverse to the holders of Shares.

A cessation of publication of the S&P GSCI-ER could materially and adversely affect the activities of the Trust.

The S&P GSCI-ER is administered, calculated and published by the Index Sponsor, which has the right to cease publication of the S&P GSCI-ER at its discretion at
any time. Under the terms of its agreement with the CME, the Index Sponsor is required, if it ceases publication of the S&P GSCI-ER, to negotiate in good faith with the CME to permit the CME to continue to calculate the S&P GSCI-ER in order
to permit CERFs to continue to trade. However, even if the Index Sponsor satisfies its obligations under its agreement with the CME, the Manager may determine that, upon a cessation of publication of the S&P GSCI-ER, it is no longer advisable to
invest in CERFs and no other futures contract that reflects the performance of a successor or reasonably similar index presents an acceptable alternative investment, in which event the Investing Pool and the Trust may be liquidated.

The rolling of the Investing Pools position in CERFs from an expiring CERF into a newly listed CERF could expose the Investing Pool to risks arising
from trading activity in CERFs.

The CERFs will expire approximately five years after their listing. Prior to any rolling of CERFs all of the CERFs
will have the same expiration date. It is anticipated that prior to the expiration date the CME will list a new CERF with an approximately five-year expiration, although the CME is under no obligation to list a later expiring CERF. As a result, it
will be necessary for the Investing Pool to roll its position in CERFs from the expiring contract into the new contract. This roll may be effected in a number of different ways, depending on the circumstances prevailing as each CERF
approaches expiration. However, it is possible that the prices obtained by the Investing Pool on the transactions executed to effect this roll will be adversely affected by market conditions (including the possibility of market disruptions) and by
the trading activities of other market participants, which may reflect market awareness of the Investing Pools position in CERFs. For example, if other market participants are able to anticipate the timing of the Investing Pools roll,
they may be able to execute transactions in advance of the Investing Pools rolling transactions, which will allow these market participants to benefit from the transactions executed by the Investing Pool but adversely affect the prices
obtained by the Investing Pool, which will in turn adversely affect the value of the Shares. In addition, if the Investing Pools CERF position represents a significant part of the open long interest, other market participants may take this
into account, with a potential adverse impact on the prices at which the Investing Pool is able to liquidate its expiring CERF position and establish a new position in the next expiring CERF contract. There can be no assurance that the Investing
Pool will effect the rolling of positions at a time or in a manner that will allow it to avoid adverse consequences.

The liquidation of CERFs could
expose the Investing Pool to the effects of temporary aberrations or distortions in the market, which could adversely affect the prices at which the Investing Pools CERF positions are liquidated.

If the Investing Pool liquidates positions in CERFs in order to satisfy redemption requests or to pay expenses and liabilities, it will do so by entering sell orders
with the Clearing FCM for execution on the CME. The resulting sales will serve to offset a portion of the Investing Pools long positions in CERFs. However, in entering sell orders, the Investing Pool will be subject to the risk that temporary
aberrations or distortions will occur in the market at the time these sales are effected and that the prices

##### Table of Contents

received by the Investing Pool on its sales could be adversely affected, thereby adversely affecting the value of the Shares. Such aberrations or distortions
could occur as a result of trading activities by other market participants or actions by the CME or regulatory authorities.

The Investing Pools
Clearing FCM could fail. Because the Investing Pool must deposit as margin an amount equal to 100% of the value of the CERFs it holds, the Investing Pool could be exposed to greater risk in the event of the bankruptcy of the Clearing FCM or the CME
clearing house.

Under CFTC regulations, a futures commission merchant, or FCM, must segregate customers assets. If a futures commission merchant
fails to do so, the customer may be subject to additional risk of loss of its funds in the event of the FCMs bankruptcy. Even if a customers funds are properly segregated, the customer still may be subject to a risk of loss if another
customer fails to satisfy deficiencies in its own account (or the FCM fails to satisfy such deficiency). As discussed below, in the case of an FCM bankruptcy, applicable provisions of the United States Bankruptcy Code and CFTC regulations generally
provide for a pro rata distribution of customer property held by a bankrupt FCM. As a result, a customer may recover only a portion of its assets held by the FCM or may recover none of its assets held by the FCM.

The Investing Pool is required to deposit with the Clearing FCM, as initial margin, 100% of the value of each CERF that it enters into on the date the position is
established. In addition, the Clearing FCM is required to deliver or pledge to the CME clearing house 100% of the value of each CERF it carries on behalf of the Investing Pool. Under the rules of the CME, the CME will have the right to apply assets
transferred or pledged to the CME by the Clearing FCM to satisfy certain of the Clearing FCMs obligations in the event of a default by the Clearing FCM.

As explained elsewhere in this annual report, this 100% margin requirement is substantially different from the initial margin requirements applicable to most other futures contracts, which are typically 3% to 7% of the value of the relevant
contract. As a result, a greater percentage of the assets of the Investing Pool will be held by the Clearing FCM and held by or pledged to the CME clearing house than would be the case if the Investing Pool entered into other types of futures
contracts. In the event of the bankruptcy of the Clearing FCM or the CME clearing house, therefore, the Investing Pool could be exposed to a risk of loss with respect to a greater portion of its assets. If such a bankruptcy were to occur, the
Investing Pool should be afforded the protections granted to customers of a futures commission merchant, and participants to transactions cleared through an exchange clearing house, under the United States Bankruptcy Code and applicable CFTC
regulations. Because such provisions generally provide for a pro rata distribution to customers of customer property held by the bankrupt futures commission merchant or clearing house if the customer property held by the futures commission merchant
or clearing house is insufficient to satisfy the customer claims, the Investing Pool may be disproportionately affected by such a bankruptcy as compared to other customers because the Investing Pool has provided a significantly higher level of
margin than have other customers. In any case, there can be no assurance that these protections will be effective in allowing the Investing Pool to recover all, or even any, of the amounts it has deposited as initial margin.

You have no recourse to the Index Sponsor.

You have no rights
against the Index Sponsor or its successors.

The Shares are not sponsored, endorsed, sold or promoted by the Index Sponsor. The Index Sponsor makes no
representation or warranty, express or implied, to the owners of the Shares or any member of the public regarding the advisability of investing in securities generally or in the Shares particularly or the ability of the S&P GSCI, the
S&P GSCI-ER or the Index, including, without limitation, all sub-indexes, to track the appropriate market performance. The Index Sponsors only relationship to Barclays Global Investors International, Inc., Barclays Global Investors, N.A.,
the Trust or the Investing Pool is the licensing of certain trademarks, trade names of the Index Sponsor and the S&P GSCI and other intellectual property. The S&P GSCI, the S&P GSCI-ER and the Index are determined and

take the needs of Barclays Global Investors International, Inc., Barclays Global Investors, N.A, the Trust, the Investing Pool or the Shareholders into consideration in determining, composing or calculating the S&P GSCI, the S&P

Risk Factors Relating to the Trust and the Investing Pool

The returns on the Shares will not precisely correlate
with the performance of the Index.

The value of and returns on the Shares are expected to reflect the value of and returns on the Trusts
underlying investments, through the Investing Pool, in CERFs and the cash or Short-Term Securities used to collateralize the CERF positions. The returns on the Shares will not precisely correlate with the performance of the Index due to 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 portion of the Investing
Pools assets invested in CERFs versus the portion of the return on the Index contributed by the S&P GSCI-ER and the payment of expenses and liabilities by the Investing Pool.

Because the Trust and the Investing Pool are passive investment vehicles, the value of the Shares may be adversely affected by losses that, if these vehicles had been actively managed, might have been possible to
avoid.

The Trustee passively invests substantially all of the Trusts assets in Investing Pool Interests, and the Advisor will manage the
Investing Pools assets in a manner that seeks to obtain returns that correspond generally to the performance of the Index, before the payment of expenses and liabilities of the Trust and the Investing Pool. This means that the net asset value
of the Investing Pool and, consequently, the NAV are intended to generally track the Index when it is flat or declining, as well as when it is rising, and, therefore, it is highly likely that the value of the Shares will be adversely affected by a
decline in commodity futures prices reflected in the Index. The Advisor will not engage in any activity designed to obtain a profit from, or to ameliorate losses caused by, changes in the value of the CERFs, any of the commodities represented by the
S&P GSCI or the other assets held by the Investing Pool, including making use of any of the hedging techniques available to professional commodity futures traders to attempt to reduce the risks of losses resulting from commodity price
decreases.

Fees and expenses payable by the Investing Pool are charged regardless of profitability and may result in a depletion of its assets.

The Investing Pool is subject to the fees and expenses described in this annual report, which are payable irrespective of profitability. These fees and
expenses include an allocation to the Manager that accrues daily at an annualized rate equal to 0.75% of the net asset value of the Investing Pool and is payable by the Investing Pool monthly in arrears.

The price you receive upon the sale of your Shares may be less than their NAV.

Shares may trade at, above or below their NAV. The NAV will fluctuate with changes in the market value of the Investing Pools assets. The trading price of Shares will fluctuate in accordance with changes in the
NAV, intraday changes in the value of the CERFs and market supply and demand. The amount of the discount or premium in the trading price of the Shares relative to their NAV may be influenced by non-concurrent trading hours between NYSE Arca, the
exchange on which the Shares trade, the CME, on which CERFs trade, and the principal commodities markets on which the futures contracts in the S&P GSCI-ER trade. While the Shares are expected to trade on NYSE Arca until 8:00 p.m., New York City
time, liquidity in the markets for the CERFs trading on the CME and for the underlying commodities in the S&P GSCI-ER will be reduced whenever the principal markets for those contracts are closed (normally 1:40 p.m. to 2:00 p.m. and 4:00 p.m. to
5:00 p.m., Chicago time, for the CERFs). As a result, trading spreads, and the resulting premium or discount on Shares, may widen during these gaps in market trading hours.

The Trust is not obligated to pay periodic distributions or dividends to Shareholders.

Interest or other income received with respect to the Trusts assets may be used to acquire additional CERFs or, in the discretion of the Sponsor, distributed to
the Shareholders. The Trust will not be obligated, however, to make any distributions to Shareholders at any time prior to the dissolution of the Trust.

The Trust could be liquidated at a time when the disposition of its interests will result in losses to investors in Shares.

If, at any
time, certain events specified in the Trust Agreement or the Investing Pool Agreement occur, the Trustee or, if applicable, the Shareholders may prompt the Trusts dissolution. Upon dissolution of the Trust, the Trust will in most circumstances
redeem its holdings in Investing Pool Interests, and the Investing Pool will sell the CERFs and securities held by it in the amount necessary to cover all expenses of liquidation and to pay any outstanding liabilities of the Trust. The remaining
assets will be distributed among investors surrendering Shares. Any property remaining in the possession of the Trustee after ninety days may be sold by the Trustee, and the proceeds of the sale will be held by the Trustee until claimed by any
remaining Shareholders. Sales of CERFs in connection with the liquidation of the Trust at a time of low prices will likely result in losses, or adversely affect your gains, on your investment in Shares.

The Manager has broad discretion to liquidate the Investing Pool at any time.

The Investing Pool Agreement provides the Manager with broad discretion to liquidate the Investing Pool at any time the Manager determines that liquidation of the Investing Pool is advisable. Liquidation of the
Investing Pool will require the Trustee to dissolve the Trust and redeem your Shares. It cannot be predicted when or under what circumstances, if any, the Manager would use this discretion to liquidate the Investing Pool. Any such liquidation may
occur at a time when you are suffering a loss on your investment in the Shares and may upset the overall maturity and timing of your investment portfolio.

Shareholders with large holdings may choose to dissolve the Trust and thereby adversely affect your investment in the Shares.

Owners of
75% or more of the Shares have the power to dissolve the Trust. This power may be exercised by a relatively small number of holders. If it is so exercised, investors who wished to continue to invest in CERFs, or the performance of the S&P
GSCI-ER, through the vehicle of the Trust will have to find another vehicle, and may not be able to find another vehicle that offers the same features as the Trust. Moreover, such a dissolution may occur at a time when you are suffering a loss on
your investment in the Shares and may upset the overall maturity and timing of your investment portfolio.

The Shares may not provide anticipated
benefits of diversification from other asset classes.

Historically, the performance of physical commodity futures prices generally has not been
correlated to the performance of financial asset classes, such as stocks and bonds. Non-correlation means that there is no statistically significant relationship, positive or negative, between the past performance of futures contracts on physical
commodities, on the one hand, and stocks or bonds, on the other hand. Because of this lack of correlation, Shares cannot be expected to be automatically profitable during unfavorable periods for the stock or bond market, or vice-versa. The commodity
futures markets are fundamentally different from the securities markets in that for every gain in commodity futures trading, there is an equal and offsetting loss. If the performance of the Shares reflects positive or negative correlation to one or
more financial asset classes, however, investing in Shares for purposes of diversification of the investment risk from such other financial asset classes may be unsuccessful.

The liquidity of the Shares may be affected by the withdrawal from participation of Authorized Participants or by the suspension of issuance, transfers or redemptions of Shares by the Trustee.

If one or more Authorized Participants withdraw from participation, it may become more difficult to create or redeem Baskets, which may reduce the liquidity of the
Shares. If it becomes more difficult to create or redeem Baskets, the correlation between the price of the Shares and the NAV may be affected, which may affect the trading market for the Shares. Having fewer participants in the market for the Shares
could also adversely affect the ability to arbitrage any price difference between the CERFs and the Shares, which may affect the trading market and liquidity of the Shares.

In addition, the Trustee has the power to suspend the delivery of Shares, registration of transfers of Shares and surrenders of Shares for the purpose of withdrawing Trust property generally, or to refuse a particular
deposit, transfer or withdrawal at any time, if the Trustee or the Sponsor determines that it is advisable to do so for any reason. The liquidity of the Shares and the correlation between the value of the Shares and the level of the Index may be
adversely affected in the event of any such suspension of issuance, transfer or redemption.

The lack of an active trading market for the Shares may result in losses on your investment at the time of disposition
of your Shares.

Although the Shares are listed on NYSE Arca, there can be no guarantee that an active trading market for the Shares will develop or be
maintained. If you need to sell your Shares at a time when no active market for them exists, the price you receive for your Shares, assuming that you are able to sell them, will likely be lower than that you would receive if an active market did
exist.

You may be adversely affected by redemption orders that are subject to postponement, suspension or rejection under certain circumstances.

The Trustee may suspend the right of redemption or postpone the redemption settlement date for such periods as it or the Sponsor deems to be necessary for
any reason. In addition, the Trustee has the absolute right to reject any redemption order, including, without limitation, (1) if the order is not in proper form as described in the Authorized Participant Agreement, (2) during any period
in which circumstances make transactions or delivery of CERFs impossible or impractical, or (3) if the acceptance of the redemption order would, in the opinion of counsel to the Trustee or the Sponsor, result in a violation of law. Any such
postponement, suspension or rejection could adversely affect a redeeming Authorized Participant. For example, the resulting delay may adversely affect the value of the redemption proceeds if the NAV declines during the period of the delay. Under the
Authorized Participant Agreement, the Trustee disclaims any liability that may result from any such suspension, postponement or rejection.

Competition
from other commodities-related investments could limit the market for, and reduce the liquidity of, the Shares.

Demand for the Shares will be affected
by the attractiveness of an investment in the Shares relative to other investment vehicles, including other commodity pools, hedge funds, traditional debt and equity securities issued by companies in the commodities industry, other securities backed
by or linked to commodities, and direct investments in commodities or commodity futures contracts. Market, financial and other conditions or factors may make it more attractive to invest in other investment vehicles or to invest in such commodities
directly, which could limit the market for, and reduce the liquidity of, the Shares.

The price of the Shares could decrease if unanticipated
operational or trading problems arise.

If the processes of creation and redemption of Shares encounter any unanticipated difficulties, potential
market participants who would otherwise be willing to purchase or redeem Baskets to take advantage of any arbitrage opportunity arising from discrepancies between the price of the Shares and the price of the underlying CERFs may choose not to do so.
If this is the case, the price of the Shares may vary from the price of the CERFs and may trade at a discount to their NAV. In addition, in some circumstances, such as the failure of the registration statement covering the Shares to be effective,
the Trust may be unable to create or redeem Shares, which may have similar consequences.

Exchange position limits and other rules may restrict the
creation of Baskets and the operation of the Investing Pool.

The CME imposes speculative position limits on market participants trading in CERFs,
including the Investing Pool, that typically prohibit any person from holding a position of more than 10,000 contracts. The Investing Pool has obtained a hedge exemption from these position limits that should permit the Investing Pool to hold up to
20,000 contracts until December 31, 2009. If the Investing Pool is unable to obtain further exemptions, or if the exemption that the Investing Pool obtained expires, is revoked or modified or cannot be renewed for any reason, then the
Trusts ability to issue new Baskets or reinvest income in additional CERFs may be limited to the extent these activities would cause the Investing Pool to exceed the then applicable position limit. Such events could force the Investing Pool to
sell CERFs, or encourage market participants to sell or redeem their Shares. Additionally, future legislative or regulatory action may impose new limitations on the size of positions that may be taken with respect to CERFs, or the CME may impose
limitations on the size of positions that may be carried by the Investing Pools Clearing FCM. Such events may also affect the liquidity of the Shares and the correlation between the price of the Shares and the net asset value of the Trust.

Exchanges may also take steps, such as requiring liquidation of open positions, in the case of disorderly markets, market congestion and other market
disruptions. These actions could require the Investing Pool to liquidate all or part of its CERF positions or require holders of positions in the futures contracts underlying the S&P GSCI-ER to liquidate their positions. This could affect the
level of the Index and the NAV.

As a Shareholder, you will not have the rights normally associated with ownership of common shares.

Shareholders are not entitled to the same rights as owners of shares issued by a corporation. By acquiring Shares, you are not acquiring the right to elect directors, to
receive dividends, to vote on certain matters regarding the Trust or to take other actions normally associated with the ownership of common shares.

As
a Shareholder, you will not have the protections normally associated with the ownership of shares in an investment company registered under the Investment Company Act.

Neither the Trust nor the Investing Pool is registered as an investment company for purposes of United States federal securities laws, and neither is subject to regulation by the SEC as an investment company.
Consequently, Shareholders will not have the regulatory protections provided to investors in investment companies registered under the Investment Company Act. For example, the provisions of the Investment Company Act that limit transactions with
affiliates, prohibit the suspension of redemptions (except under limited circumstances) and limit sales loads will not apply to the Trust or the Investing Pool. BGII , as the Sponsor and the Manager, is registered with the CFTC as a commodity pool
operator, and Barclays Global Fund Advisors, as the Advisor, is registered with the CFTC as a commodity trading advisor. The CFTC therefore has jurisdiction over these entities and regulatory authority over certain activities of the Trust and the
Investing Pool. The nature and degree of this regulation differs from the regulatory scheme imposed under the Investment Company Act.

Competing claims
over ownership of relevant intellectual property rights could adversely affect the Trust, the Investing Pool or an investment in the Shares.

While
BGII believes that it has all the intellectual property rights needed to operate the Trust and the Investing Pool, third parties may allege or assert ownership of intellectual property rights that may be related to the design, structure and
operation of the Trust, the Investing Pool or the Index. To the extent any claims of such ownership are brought or any proceedings are instituted to assert such claims, the negotiation, litigation or settlement of such claims, the issuance of any
restraining orders or injunctions, or the ultimate disposition of such claims in a court of law, may adversely affect the Trust, the Investing Pool and the value of the Shares. For example, such actions could result in expenses or damages payable by
the Trust or the Investing Pool or the suspension of activities or dissolution of the Trust or the Investing Pool.

The value of the Shares will be
adversely affected if the Trust is required to indemnify the Sponsor or if the Investing Pool is required to indemnify the Manager.

Under the Trust
Agreement, the Sponsor has the right to be indemnified by the Trust for any liability or expense it incurs without negligence, bad faith or willful misconduct on its part. That means the Sponsor may require the assets of the Trust to be sold in
order to cover losses or liability suffered by it, which would reduce the net asset value of the Trust and the value of the Shares. Likewise, under the Investing Pool Agreement, the Manager and agents of the Investing Pool have the right to be
indemnified by the Investing Pool for any liability or expense they incur without gross negligence, bad faith or willful misconduct on their part. That means the Manager may require the assets of the Investing Pool to be sold in order to cover
losses or liabilities suffered by it, which would reduce the net asset value of the Investing Pool and thereby affect the net asset value of the Trust and the value of the Shares.

Regulatory changes or actions may affect the Shares.

The futures markets are subject to comprehensive regulation.
In addition, the CFTC and the exchanges are authorized to take extraordinary actions in the event of a market emergency, including, for example, implementing retroactively speculative position limits or higher margin requirements, establishing daily
price limits and suspending trading. The regulation of futures transactions in the United States is subject to modification by government and judicial action. The effect of any future regulatory change on the Trust or the Investing Pool is
impossible to predict, but could be substantial and adverse.

NYSE Arca may halt trading in the Shares, which would adversely impact your ability to
sell your Shares.

The Shares are listed for trading on NYSE Arca under the symbol GSG. Trading in the Shares may be halted due to market
conditions or, in light of NYSE Arca rules and procedures, for reasons that, in the view of NYSE Arca, make trading in the Shares inadvisable, or in the event certain information about the Index, the value of the Shares and the NAV is not made

available as required by such rules and procedures. In addition, trading generally on NYSE Arca is subject to trading halts caused by extraordinary market
volatility pursuant to circuit breaker rules that require trading to be halted for a specified period based on a specified market decline. There can be no assurance that the requirements necessary to maintain the listing of the Shares
will continue to be met or will remain unchanged. The Trust will be dissolved if the Shares are delisted from NYSE Arca and are not approved for listing on another national securities exchange within five Business Days of their delisting.

Risk Factors Relating to Conflicts of Interest

The
relationships between the Sponsor and the Trustee and the Manager and the Advisor and the proprietary and managed trading activities of the Sponsor and its affiliates could conflict with your interests as a Shareholder.

The Sponsor is an affiliate of the Trustee and therefore may have a conflict of interest with respect to its oversight of the Trustee. In particular, the Sponsor, which
has authority to remove the Trustee in its discretion, has an incentive not to exercise this authority, even when it is in the best interests of the Shareholders to do so, because of the affiliation between the entities. The Trustee is authorized to
appoint an unaffiliated Trust Administrator or agent to carry out all or some of its duties under the Trust Agreement, but it can terminate or replace the Trust Administrator or agent at any time, and it is not required to delegate any of its duties
to an unaffiliated third party.

The Manager is an affiliate of the Advisor and therefore may have a similar conflict of interest with respect to its
oversight of the Advisor. For example, although the Manager has the authority to terminate the Investing Pools advisory agreement with the Advisor, it has an incentive not to exercise this authority, even when it is in the best interests of
the Shareholders to do so, because of the affiliation between the entities.

In addition, the Sponsor and its affiliates may engage in trading activities
relating to the CERFs, the components of the Index or the S&P GSCI-ER or other derivative instruments related to those indices that are not for the account of, or on behalf of, the Trust, the Investing Pool or the Shareholders and that may
compete with trading activity in the Shares. These activities may present a conflict between the Shareholders interest in the Shares and the interest of the Sponsor and its affiliates in their proprietary accounts, in facilitating
transactions, including derivatives transactions, for their customers accounts and in accounts under their management. These trading activities, if they influence the value of the CERFs or the Shares, could be adverse to the interests of the
Shareholders. Moreover, the Sponsor and its affiliates have published and in the future expect to publish research reports with respect to commodities markets. This research may express opinions or provide recommendations that are inconsistent with
purchasing or holding Shares. The research should not be viewed as a recommendation or endorsement of the Shares in any way, and investors must make their own independent investigation of the merits of this investment. Any of these activities by the
Sponsor and its affiliates may affect the level of the S&P GSCI-ER or its components and, therefore, the value of the CERFs and the price of the Shares.

Proprietary trading and other activities by Goldman, Sachs & Co. and its affiliates could conflict with your interests as a Shareholder.

Activities conducted by Goldman, Sachs & Co. and its affiliates may conflict with your interests as a Shareholder. For example, the Advisor may execute a substantial amount, and potentially all, of the purchases and sales of CERFs
through Goldman, Sachs & Co., as the Investing Pools Clearing FCM. In addition, Goldman, Sachs & Co. and its affiliates actively trade futures contracts and options on futures contracts on the commodities that underlie the
S&P GSCI, over-the-counter contracts on these commodities, the underlying commodities included in the S&P GSCI and other instruments and derivative products based on the S&P GSCI and the S&P GSCI-ER. Any of these
activities of Goldman, Sachs & Co. or its affiliates could adversely affect the level of the S&P GSCI-ER or CERFs, directly or indirectly, by affecting the price of the underlying commodities and, therefore, the value of the S&P
GSCI-ER, CERFs and the price of the Shares.

Goldman, Sachs & Co. and its affiliates may also issue or underwrite other securities or financial or
derivative instruments with returns indexed to the S&P GSCI, the S&P GSCI-ER or the Index, which would compete with the Shares. By introducing competing products into the marketplace, Goldman, Sachs & Co. and its affiliates
could adversely affect the price of the Shares. To the extent that Goldman, Sachs & Co. or its affiliates serve as issuer, agent or underwriter of those securities or other similar instruments, their interests with respect to those products
may be adverse to your interests as a Shareholder.

Risk Factors Relating to Taxes

The IRS could take the position that CERFs must be taxed under special mark-to-market rules that would require gain to be taken into account on an annual basis.

Futures contracts that require a person such as the Investing Pool to make an initial deposit of 100% margin and that do not require or permit the payment by that person
of additional variation margin are a novel form of futures contract. Consequently, no statutory, judicial or administrative authority addresses the characterization of a CERF owned by the Investing Pool or the U.S. federal income tax consequences of
an investment in the CERFs by the Investing Pool. The Investing Pool has received an opinion that, while there is no authority on point, the CERFs held by the Investing Pool will not be treated as regulated futures contracts within the meaning of
section 1256 of the Code because the CERFs are not contracts with respect to which the amount required to be deposited and the amount which may be withdrawn depends on a system of marking to market. You should be aware that an opinion is not binding
on the Internal Revenue Service or a court. Accordingly, it is possible that the Internal Revenue Service or a court would reach the conclusion that the CERFs should be treated as regulated futures contracts within the meaning of section 1256 of the
Code. In that case, the timing, amount, character, holding period or other material aspects of your income, gain, loss or expense from an investment in the Shares could be significantly affected. In particular, you would be taxable on any gain on
the CERFs on an annual mark-to-market basis, regardless of the fact that the CERFs have a term of five years.

Your tax liability could exceed cash
distributions on your Shares.

You will be required to pay U.S. federal income taxes on your allocable share of the Trusts and the Investing
Pools income, without regard to the receipt of cash distributions on the Shares. There is no obligation to make distributions on the Shares. Accordingly, it is anticipated that you will not receive cash distributions sufficient to cover your
allocable share of such taxable income or even the tax liability resulting from that income.

The IRS could adjust or reallocate items of income, gain,
deduction, loss and credit with respect to the Shares if the IRS does not accept the assumptions or conventions utilized by the Trust or the Investing Pool.

The U.S. tax rules that apply to partnerships are complex and their application is not always clear. Moreover, the rules generally were not written for, and in some respects are difficult to apply to, publicly traded interests in
partnerships. The Trust and the Investing Pool will apply certain assumptions and conventions intended to comply with the intent of the rules and to report income, gain, deduction, loss and credit to investors in a manner that reflects the
investors economic gains and losses, but these assumptions and conventions may not comply with all aspects of the applicable Treasury regulations. It is possible therefore that the IRS will successfully assert that these assumptions or
conventions do not satisfy the technical requirements of the Code or the Treasury regulations and will require that items of income, gain, deduction, loss and credit be adjusted or reallocated in a manner that could be adverse to you.

Item 5. Market for Registrants Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities.

a) On December 27, 2007 the Shares commenced trading on NYSE Arca under the symbol GSG. Prior to that, the Shares were traded on the NYSE, also under the
symbol GSG, since their initial public offering on July 19, 2006. For each of the quarters during the fiscal years ended December 31, 2008 and December 31, 2007, the high and low sale prices of the Shares as reported for
transactions on the NYSE and NYSE Arca were as follows:



|                                    |  |      |       |     |   |

|Fourth Quarter                      |  | $    | 53.27 |     | $ | 45.77

The number of holders of the Shares of the registrant as of January 30, 2009 was 135.

The Trust made no distributions to Shareholders during the fiscal years ended December 31, 2008 and December 31, 2007. The Trust has no obligation to make
periodic distributions to Shareholders.

There is no public trading market for the Investing Pool Interests.

b) As described in the Trusts first registration statement on Form S-1 (No. 333-126810), which was declared effective on July 19, 2006, proceeds received by
the Trust from the issuance and sale of Shares to Authorized Participants generally consist of long positions in CERFs and cash or short-term or similar securities, referred to as Short-Term Securities, in lieu of cash. Such proceeds are
delivered to the Investing Pool in return for interests in the Investing Pool. These assets are held on behalf of the Investing Pool in an account with the Clearing FCM until withdrawn in connection with redemptions of Shares or liquidated to pay
expenses and liabilities of the Trust and the Investing Pool not assumed by the Sponsor or the Manager.

c) During the fourth quarter of fiscal year 2008,
91 Baskets (4,550,000 Shares) were created, and 21 Baskets (1,050,000 Shares) were redeemed.

Introduction

As described in Part I above, it is the objective of the Trust that the performance of the Shares correspond
generally to the performance of the S&P GSCI Total Return Index, or the Index, before payment of the Trusts and the Investing Pools expenses and liabilities. The Index is
intended to reflect the performance of a diversified group of commodities. During the period beginning July 10, 2006 (commencement of operations) and ending on December 31, 2008 (the Trusts most recent fiscal year-end), the
Trusts investment in the Investing Pool grew from $7,358,911 at July 10, 2006 to $466,237,257 at December 31, 2008. Outstanding shares in the Trust grew from 150,000 shares at July 10, 2006 to 16,950,000 shares outstanding at
December 31, 2008.

Results of Operations

The year ended December 31, 2008

Net Asset Value of Trust

The Trusts net asset value grew from $458,195,417 at December 31, 2007 to $466,237,257 at December 31, 2008. The increase in the Trusts net asset value resulted primarily from an increase in
outstanding Shares, which rose from 8,750,000 at December 31, 2007 to 16,950,000 at December 31, 2008 due to 14,650,000 Shares (293 Baskets) being created and 6,450,000 Shares (129 Baskets) being redeemed during the
year. This outstanding share increase was offset by a decrease in the price of CERFs during the year ended December 31, 2008, in which the price decreased from $740.40 per CERF to $382.50 per CERF, a 48.34% decrease. This decline
in the CERF price was attributable to the deterioration in the global economic environment and a weakening credit environment, which combined to adversely affect commodity prices in the second half of 2008.

The year ended December 31, 2007

Net Asset Value of Trust

The Trusts net asset value grew from $143,425,669 at December 31, 2006 to $458,195,417 at December 31, 2007. The increase in the
Trusts net asset value resulted primarily from an increase in outstanding Shares, which rose from 3,600,000 at December 31, 2006 to 8,750,000 at December 31, 2007 due to 5,900,000 Shares (118 Baskets) being created and 750,000 Shares
(15 Baskets) being redeemed during the year. The Trusts net asset value was also affected by an increase in the price of CERFs during the year ended December 31, 2007, which price increased from $586.50 per CERF to $740.40 per CERF, a
26.24% increase.

The period from July 10, 2006 to December 31, 2006

Net Asset Value of Trust

The Trust commenced trading on July 10,
2006. The Trusts net asset value grew from $7,358,911 at July 10, 2006 to $143,425,669 at December 31, 2006. The increase in the Trusts net asset value resulted primarily from an increase in outstanding Shares, which rose from
150,000 at July 10, 2006 to 3,600,000 at December 31, 2006 due to 3,800,000 Shares (76 Baskets) being created and 350,000 Shares (7 Baskets) being redeemed during the period. The Trusts net asset value was also affected by a decline
in the price of CERFs during the period from July 10, 2006 to December 31, 2006, which price decreased from $738 per CERF to $586.50 per CERF, a 20.53% decrease.

Liquidity and Capital Resources

The Trusts sole asset as of December 31, 2008 was its investment in the
Investing Pool, which is illiquid. The Investing Pools assets consist of CERFs and cash and Short-Term Securities that are posted as collateral for the Investing Pools CERF positions. The Trust and the Investing Pool do not anticipate
any further need for liquidity because creations and redemptions of Shares generally occur in kind and ordinary expenses are met by cash on hand. Interest earned on the assets posted as collateral is paid to the Investing Pool and is used to pay the
fixed fee to the Manager and purchase additional CERFs, or, in the discretion of the Sponsor, distributed to Shareholders. For the year ended December 31, 2008, interest income was $14,683,161, while the fixed fee totaled $5,181,296. For the
year ended December 31, 2007, interest income was $13,173,455, while the fixed fee totaled $2,091,684. From the date of commencement of operations to December 31, 2006, interest income was $1,713,961, while the fixed fee totaled $250,273.
For the year ended December 31, 2008, the fixed fee comprised a greater proportion of interest income than the proportion applicable to the year ended December 31, 2007. A prolonged decline in interest rates could materially affect the
amount of interest paid to the Investing Pool. In exchange for a fee based on the net asset value of the Investing Pool, the Sponsor and the Manager have assumed most of the ordinary expenses incurred by the Trust and the Investing Pool. In the case
of an extraordinary expense, however, the Investing Pool could be forced to liquidate its CERF positions to pay such expenses.

The Sponsor is unaware of
any other trends, demands, conditions or events that are reasonably likely to result in material changes to the Trusts or the Investing Pools liquidity needs.

Because the Investing Pool trades CERFs, its capital is at risk due to changes in the value of the CERFs or other assets (market risk) or the inability of counterparties to perform (credit risk).

Market Risk

The Investing Pool holds CERF positions and posts cash
and Short-Term Securities as margin to collateralize the CERF positions. Because of this limited diversification of the Investing Pools assets, fluctuations in the value of the CERFs are expected to directly affect the value of the Shares. The
value of the CERFs is expected to track generally the S&P GSCI-ER, although this correlation may not be exact. The S&P GSCI-ER, in turn, reflects the value of a diversified group of commodities. The market risk associated with the Investing
Pools CERF positions is limited to the amount of cash and Short-Term Securities posted as margin. The Investing Pools exposure to market risk will be influenced by a number of factors, including the liquidity of the CERF market and
activities of other market participants.

Credit Risk

When the Investing Pool purchases or holds CERFs, it is exposed to the credit risk of a default by the CME clearinghouse, which serves as the counterparty to each CERF position, and of a default by the Clearing FCM. In the case of such a
default, the Investing Pool could be unable to recover amounts due to it on its CERF positions and assets posted as margin. The Investing Pool is also exposed to the credit risk of the obligors of any Short-Term Securities posted as margin. See also
Risk FactorsRisk Factors Related to CERFs and the S&P GSCI-ERThe Investing Pools Clearing FCM could fail. Because the Investing Pool must deposit as margin an amount equal to 100% of the value of the CERFs it holds, it
could be exposed to greater risk in the event of the bankruptcy of the Clearing FCM or the CME clearinghouse.

Off-Balance Sheet Arrangements and
Contractual Obligations

The Trust and the Investing Pool have not used, nor do they expect to use, special purpose entities to facilitate off-balance
sheet financing arrangements. The Trust and the Investing Pool have no loan guarantee arrangements or other off-balance sheet arrangements of any kind other than agreements entered into in the normal course of business, which may include
indemnification

provisions related to certain risks service providers undertake in performing services that are in the interest of the Trust and the Investing Pool. While
the Trusts and the Investing Pools exposure under such indemnification provisions cannot be estimated, these general business indemnifications are not expected to have a material impact on either the Trusts or the Investing
Pools financial position.

Critical Accounting Policies

The financial statements and accompanying notes are prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of these financial statements relies on estimates and assumptions that
impact the Trusts and the Investing Pools financial position and results of operations. These estimates and assumptions affect the Trusts and the Investing Pools application of accounting policies. In addition, please refer
to Note 2 to the financial statements of the Trust and the Investing Pool for further discussion of the Trusts and the Investing Pools accounting policies.

Current Accounting Developments

In March 2008, the Financial Accounting Standards Board issued Financial Accounting
Standards Statement No. 161, Disclosures about Derivative Instruments and Hedging Activities, an amendment of FASB Statement No. 133 (FAS 161). FAS 161 enhances the disclosures for derivative instruments and hedging
activities. The statement is effective for fiscal years and interim periods beginning after November 15, 2008. The Trust and Investing Pool are currently evaluating the impact that FAS 161 may have on their financial statements.

Item 7A. Quantitative and Qualitative Disclosures about Market Risk.

Quantitative Disclosure

The Trust and Investing Pool are exposed to commodity price risk through the Investing
Pools holdings of CERFs. The following table provides information about the Investing Pools futures contract positions, which are sensitive to changes in commodity prices. As of December 31, 2008, the Investing Pools open CERF
positions (long) were as follows:



|                                    |  |   |            
|----------------------------------- |  | - | -----------
|Number of Contracts                 |  |   | 12,122     
|Expiration Date                     |  |   | March 2011 
|Weighted-Average Price per Contract |  | $ | 656.39     
|Fair Value                          |  | $ | 463,666,500

Fair value is calculated using the settlement price for the CERFs on the CME on December 31, 2008, which was
$382.50 per contract, and the $100 multiplier applicable under the contract terms.

Qualitative Disclosure

As described herein, it is the objective of the Trust, through its investment in the Investing Pool, that the performance of the Shares will correspond generally to the
performance of the Index, before payment of expenses and liabilities. The Index itself is intended to reflect the performance of a diversified group of physical commodities, including energy commodities, precious and industrial metal commodities,
agricultural commodities and livestock commodities. The Trust obtains this exposure to commodity prices through the Investing Pools CERF positions. As a result, fluctuations in the value of the CERFs are expected to directly affect the value
of the Shares.

Neither the Trust nor the Investing Pool will engage in any activities designed to obtain a profit from, or ameliorate losses caused by,
changes in the value of the CERFs, any commodities underlying the Index or the S&P GSCI-ER, or any assets posted as margin. Because of the 100% margin requirement applicable to the Investing Pools CERF positions, the market risk associated
with the Investing Pools CERF position is limited to the amount of cash and Short-Term Securities posted as margin.

Item 9. Changes in and Disagreements with Accountants on Accounting and Financial
Disclosure.

Not applicable.

Item 9A. Controls and Procedures.

The duly authorized officers of the Sponsor and Manager performing
functions equivalent to those a principal executive officer and principal financial officer of the Trust and the Investing Pool would perform if the Trust and the Investing Pool had any officers, and with the participation of the Trustee and the
Investing Pool administrator, have evaluated the effectiveness of the Trusts and Investing Pools disclosure controls and procedures, and have concluded that the disclosure controls and procedures of the Trust and Investing Pool were
effective as of the end of the period covered by this report to provide reasonable assurance that information required to be disclosed in the reports that the Trust and the Investing Pool file or submit under the Securities Exchange Act of 1934, as
amended, is recorded, processed, summarized and reported, within the time periods specified in the applicable rules and forms, and that it is accumulated and communicated to the duly authorized officers of the Sponsor and Manager performing
functions equivalent to those a principal executive officer and principal financial officer of the Trust and the Investing Pool would perform if the Trust and the Investing Pool had any officers, as appropriate to allow timely decisions regarding
required disclosure.

There are inherent limitations to the effectiveness of any system of disclosure controls and procedures, including the possibility of
human error and the circumvention or overriding of the controls and procedures.

Managements Report on Internal Control over Financial Reporting

The Sponsors and Managers management is responsible for establishing and maintaining adequate internal control over financial reporting, as
defined in Exchange Act Rules 13a-15(f) and 15d-15(f). The Trusts and Investing Pools internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and
the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in the United States of America. Internal control over financial reporting includes those policies and procedures that:
(1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the Trusts and Investing Pools assets; (2) provide reasonable assurance that transactions
are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that the Trusts and Investing Pools receipts and expenditures are being made only in accordance with
appropriate authorizations; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the Trusts and Investing Pools assets that could have a material effect on
the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also,
projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become ineffective because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

The principal executive officer and principal financial officer of the Sponsor and Manager assessed the effectiveness of the Trusts and Investing
Pools internal control over financial reporting as of December 31, 2008. Their assessment included an evaluation of the design of the Trusts and Investing Pools internal control over financial reporting and testing of the
operational effectiveness of their internal control over financial reporting. In making its assessment, the Sponsors and Managers management has utilized the criteria set forth by the Committee of Sponsoring Organizations of the Treadway
Commission (COSO) in its report entitled Internal Control  Integrated Framework. Based on their assessment and those criteria, the principal executive officer and principal financial officer of the Sponsor and Manager conclude that the
Trust and Investing Pool maintained effective internal control over financial reporting as of December 31, 2008.

The effectiveness of the
Trusts and Investing Pools internal control over financial reporting as of December 31, 2008 has been audited by PricewaterhouseCoopers LLP, the independent registered public accounting firm that audited and reported on the
financial statements included in this annual report, as stated in their reports which are included herein.

Changes in Internal Control over Financial
Reporting

There were no changes in the Trusts and Investing Pools internal control over financial reporting that occurred during the
Trusts and Investing Pools fourth fiscal quarter of the period covered by this report that have materially affected, or are reasonably likely to materially affect, the Trusts and Investing Pools internal control over
financial reporting.

PricewaterhouseCoopers LLP provides certain tax compliance and reporting services to the Trust, including
processing beneficial ownership information as it relates to the preparation of tax reporting packages and the subsequent delivery of related information to the IRS. Services also include assistance with tax reporting and related information using a
web-based tax package product developed by PricewaterhouseCoopers LLP and a toll-free tax package support help line.

(5) The Registrants have no boards of
directors, and as a result, has no audit committee and no pre-approval policies or procedures with respect to fees paid to PricewaterhouseCoopers LLP.

(6)
None of the hours expended on PricewaterhouseCoopers LLPs engagement to audit the Registrants financial statements for the year ended December 31, 2008 were attributable to work performed by persons other than the principal
accountants full-time, permanent employees.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Sponsor, Trustee and Shareholders of

iShares® S&P GSCI Commodity-Indexed Trust:

In our opinion, the financial statements listed in the accompanying index present fairly, in all material respects, the financial position of iShares S&P GSCI
Commodity-Indexed Trust (the Trust) at December 31, 2008 and December 31, 2007, and the results of its operations and its cash flows for the years ended December 31, 2008 and 2007 and the period from July 10, 2006
through December 31, 2006 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Trust maintained, in all material respects, effective internal control over financial reporting as
of December 31, 2008, based on criteria established in Internal Control  Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Sponsors management is responsible for
these financial statements, for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Managements Report on
Internal Control over Financial Reporting. Our responsibility is to express opinions on these financial statements and on the Trusts internal control over financial reporting based on our audits, which was an integrated audit in 2008. We
conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements
are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts
and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting
included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk.
Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

A trusts internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external
purposes in accordance with generally accepted accounting principles. A trusts internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail,
accurately and fairly reflect the transactions and dispositions of the assets of the trust; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally
accepted accounting principles, and that receipts and expenditures of the trust are being made only in accordance with authorizations of management and directors of the trust; and (iii) provide reasonable assurance regarding prevention or
timely detection of unauthorized acquisition, use, or disposition of the trusts assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become
inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

iShares® S&P GSCI Commodity-Indexed Trust

Notes to Financial Statements

December 31, 2008



1  Organization

The iShares® S&P GSCI Commodity-Indexed Trust, or the Trust, was organized as a Delaware statutory trust on July 7, 2006 and commenced operations on July 10, 2006. Prior to May 9, 2007,
the Trust was known as the iShares® GSCI® Commodity-Indexed Trust. Barclays Global Investors International, Inc. is the
Sponsor of the Trust and Barclays Global Investors, N.A. is the Trustee of the Trust. The Trust is governed by the Amended and Restated Trust Agreement, dated as of September 12, 2007 (the Trust Agreement), among
the Sponsor, the Trustee and Wilmington Trust Company (the Delaware Trustee). The Trust issues units of beneficial interest, or Shares, representing fractional undivided beneficial interests in its net assets. Substantially
all of the net assets of the Trust consist of its holdings of the limited liability company interests of a commodity pool, which are the only securities in which the Trust may invest. That commodity pool, iShares® S&P GSCI Commodity-Indexed Investing Pool LLC, or the Investing Pool, holds long positions in futures contracts on the S&P GSCI Excess Return Index listed on the Chicago Mercantile Exchange called Commodity Excess Return Futures, or CERFs, and posts margin in the form of cash or short-term or similar
securities, referred to as Short-Term Securities, to collateralize its CERF positions. Margin has to be posted at the time the CERF position is established.

It is the objective of the Trust that the performance of the Shares will correspond generally to
the performance of the S&P GSCI Total Return Index before payment of the Trusts and the Investing Pools expenses.

The Trust and the Investing Pool are each commodity pools, as defined in the Commodity Exchange Act and the applicable regulations of the Commodity
Futures Trading Commissions, or CFTC, and are operated by Barclays Global Investors International, Inc., a commodity pool operator registered with the CFTC. Barclays Global Investors International, Inc. is an indirect subsidiary of
Barclays Bank PLC.

Neither the Trust nor the Investing Pool is an investment company registered under the Investment Company Act of 1940,
as amended.

2  Summary of Significant Accounting Policies

A. Basis of Accounting

The accompanying financial statements have been prepared in conformity with
U.S. GAAP. The preparation of financial statements in conformity with U.S. GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and
liabilities at the date of the financial statements. Actual results could differ from those estimates and these differences could be material.

B. Investment in the Investing Pool

The Trusts investment in the Investing Pool is valued at an amount equal to the
value of the Trusts capital account in the Investing Pool, which is measured at fair value.

The financial statements of the
Investing Pool should be read in conjunction with the Trusts financial statements.

At December 31, 2008, the Trust owned 99.99%
of the Investing Pools net assets. Because the Trust invests substantially all of its assets in the Investing Pool, the accounting policies of the Investing Pool, including the Investing Pools security valuation policies, will directly
affect the recorded value of the Trusts

investment in the Investing Pool. The Trust also receives a daily allocation of its respective income, expenses and net realized and unrealized gains and
losses in proportion to its investment in the Investing Pool.

C. Income Taxes

The Trust is not an association taxable as a corporation for federal, state and local income tax purposes.

On September 12, 2007, the Sponsor, the Trustee and the Delaware Trustee entered into an amended and restated Trust Agreement with respect to the
Trust. The amended and restated Trust Agreement amended and restated in its entirety the Trust Agreement, dated as of July 7, 2006, among the Sponsor, the Trustee and the Delaware Trustee, to add certain tax-related provisions relating to the
filing of a partnership tax return by the Trust. The amended and restated Trust Agreement does not alter the economic rights of investors in the Trust. Rather, it changes only the form of tax reporting investors will receive from the Trust. As a
result of the filing of a partnership tax return by the Trust, investors will receive tax reporting information with respect to their investments in the Trust on IRS Schedule K-1 rather than IRS Form 1099.

No provision for federal, state, and local income taxes has been made in the accompanying financial statements because the Trust is not subject to income
taxes. Shareholders are individually responsible for their own tax payments on their proportionate share of gains, losses, credits, or deductions.

D. Calculation of Net Asset Value

The net asset value of the Trust on any given day is obtained by subtracting the
Trusts accrued expenses and other liabilities on that day from the value of (1) the Trusts equity investment in the Investing Pool and (2) any other assets of the Trust, as of 4:15 p.m., New York City time, that day. The
Trustee determines the net asset value per Share (the NAV) by dividing the net asset value of the Trust on a given day by the number of Shares outstanding or deemed to be outstanding at 4:15 p.m., New York City time, that day. The NAV is
calculated each day on which NYSE Arca is open for regular trading, as soon as practicable after 4:15 p.m., New York City time.

E.
Distributions

Interest and distributions received by the Investing Pool on the assets posted as margin may be used to acquire
additional CERFs or, in the discretion of the Sponsor, distributed to Shareholders. The Trust is under no obligation to make periodic distributions to Shareholders.

3  Offering of the Shares

Shares are issued and redeemed continuously in one or more blocks of
50,000 Shares in exchange for a combination of CERFs and cash (or, in the discretion of the Sponsor, Short-Term Securities in lieu of cash). The baskets of CERFs and cash (or, in the discretion of the Sponsor, Short-Term Securities in lieu of cash)
are transferred to or from the Investing Pool in exchange for limited liability company interests in the Investing Pool. In addition, the Investing Pool, and some other types of market participants, are required to deposit cash margin with their
futures commission merchant with a value equal to 100% of the value of each CERF position at the time it is established. Individual investors cannot purchase or redeem Shares in direct transactions with the Trust. The Trust transacts only with
registered broker-dealers that have entered into a contractual arrangement with the Trust and the Sponsor governing, among other matters, the creation and redemption processes (such authorized broker-dealers are the Authorized
Participants). Authorized Participants may redeem their Shares (as well as Shares on behalf of other investors) at any time on any business day in one or more blocks of 50,000 Shares.

December 31, 2008



Redemptions of Shares in exchange for baskets of CERFs and cash (or, in the discretion of the Sponsor, Short-Term Securities in lieu of cash) are treated as
sales for financial statement purposes.

On December 31, 2008, the Trust had 16,950,000 Shares outstanding.

4  Trust Expense

The Trust is not expected to

listing fees, (3) printing and mailing costs, (4) audit fees, (5) tax reporting costs, (6) license fees, and (7) up to $100,000 per annum in legal fees. The Sponsor has also paid the costs of the Trusts organization
and the initial sales of the Shares, including applicable SEC registration fees.

5  Related Parties

The Sponsor, the Manager and the Trustee are considered to be related parties to the Trust. The Trustees fee is paid by the Sponsor and is not a
separate expense of the Trust. The Manager is paid by the Investing Pool and that fee is an indirect expense of the Trust.

6  Indemnification

The Sponsor and its shareholders, directors, officers, employees, affiliates (as such term is defined under the Securities Act of 1933,
as amended) and subsidiaries are entitled to be indemnified by the Trust and held harmless against any loss, liability or expense arising out of or in connection with the performance of their obligations under the Trust Agreement or any actions
taken in accordance with the provisions of the Trust Agreement and incurred without their (1) negligence, bad faith, willful misconduct or willful malfeasance or (2) reckless disregard of their obligations and duties under the Trust
Agreement.

7  Commitments and Contingent Liabilities

In the normal course of business, the Trust may enter into contracts with service providers that contain general indemnification clauses. The Trusts maximum exposure under these arrangements is unknown as this
would involve future claims that may be made against the Trust that have not yet been made.

8  Net Asset Value and Financial Highlights

The Trust is presenting the following net asset values and financial highlights related to investment performance and operations for a
Share outstanding for the years ended December 31, 2008 and 2007 and the period from July 10, 2006 (commencement of operations) to December 31, 2006. The net investment income and total expense ratios are calculated using average net
asset value, and the ratios for the period from July 10, 2006 (commencement of operations) to December 31, 2006 have been annualized. The net asset value presentation is calculated using daily Shares outstanding. The net investment income
and total expense ratios include the allocation of net investment income and expenses from the Investing Pool. The net investment income and expense ratios for the period from July 10, 2006 (commencement of operations) to December 31, 2006
have been annualized. The total return is based on the change in net asset value of a Share during the period. An investors return and ratios may vary based on the timing of capital transactions.

9  Investment Valuation

Effective January 1, 2008, the Trust adopted Financial Accounting Standards Board (FASB) Statement of Financial Accounting Standards No. 157 (FAS 157), Fair Value Measurements. This
standard establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. Inputs may be based on independent market data (observable inputs) or they may be internally developed
(unobservable inputs). The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3
measurements). The three levels of the fair value hierarchy under FAS 157 are as follows:



|        |  |   |  |                                                                                                                                                                                                        
|------- |  | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
|Level 1 |  |  |  | Inputs that reflect unadjusted quoted prices in active markets for identical assets or liabilities that the Trust has the ability to access as of the measurement date;                                
|Level 2 |  |  |  | Inputs other than quoted prices included within Level 1 that are observable for the asset or liability either directly or indirectly, including inputs in markets that are not considered to be
active;
|Level 3 |  |  |  | Inputs that are unobservable for the asset or liability.                                                                                                                                               

Substantially all of the net assets of the Trust consist of its interests in the Investing Pool,
which are measured at fair value. The interests in the Investing Pool are classified as a Level 2, as there is not an active market for interests in the Investing Pool, while all significant inputs for the value of the Investing Pool are
directly observable to the Trust. At December 31, 2008, the fair value of the interests equaled $466,237,257.

Disclosure regarding
fair value measurements relating to the Investing Pools investment portfolio can be found in Note 10 of the Investing Pools Notes to Financial Statements.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Manager and Members of

iShares® S&P GSCICommodity-Indexed Investing Pool LLC:

In our opinion, the financial statements listed in the accompanying index present fairly, in all material
respects, the financial position of iShares S&P GSCI Commodity-Indexed Investing Pool LLC (the Investing Pool) at December 31, 2008 and 2007, and the results of its operations and its cash flows for the years ended
December 31, 2008 and 2007 and the period from July 10, 2006 through December 31, 2006 in conformity with accounting principles generally accepted in the United States of America. In addition, in our opinion, the financial statement
schedule listed in the accompanying index presents fairly, in all material respects, the information set forth therein when read in conjunction with the related financial statements. Also in our opinion, the Investing Pool maintained, in all
material respects, effective internal control over financial reporting as of December 31, 2008, based on criteria established in Internal Control  Integrated Framework issued by the Committee of Sponsoring Organizations of the
Treadway Commission (COSO). The Sponsors management is responsible for these financial statements and financial statement schedule, for maintaining effective internal control over financial reporting and for its assessment of the effectiveness
of internal control over financial reporting, included in the accompanying Managements Report on Internal Control over Financial Reporting. Our responsibility is to express opinions on these financial statements, on the financial statement
schedule, and on the Investing Pools internal control over financial reporting based on our audits, which was an integrated audit in 2008. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight
Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial
reporting was maintained in all material respects. Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and
significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing
the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the
circumstances. We believe that our audits provide a reasonable basis for our opinions.

A companys internal control over financial reporting is a
process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A companys
internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the
company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company
are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the
companys assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial
reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance
with the policies or procedures may deteriorate.

iShares® S&P GSCI Commodity-Indexed Investing Pool LLC

Notes to Financial Statements

December 31, 2008



1  Organization

The iShares® S&P GSCI Commodity-Indexed Investing Pool LLC, or the Investing Pool, is a limited liability company organized under the laws of the State of Delaware on July 7, 2006 and commenced
operations on July 10, 2006. Prior to May 9, 2007, the Investing Pool was known as the iShares® GSCI® Commodity-Indexed
Investing Pool LLC. Barclays Global Investors International, Inc. (the Manager) is responsible for the administration of the Investing Pool. The Investing Pool holds long positions in futures contracts on the S&P GSCI Excess Return Index, or S&P GSCI-ER, listed on the Chicago Mercantile Exchange, or the CME, called Commodity Excess Return Futures, or CERFs, and posts
margin in the form of cash or short-term or similar securities, referred to as Short-Term Securities, to collateralize its CERF positions.

It is the objective of the Investing Pool that its performance will correspond generally to the
performance of the S&P GSCI Total Return Index, or the Index, before payment of the Investing Pools expenses.

The Investing Pool is a commodity pool, as defined in the Commodity Exchange Act and the applicable regulations of the Commodity Futures Trading
Commissions, or CFTC, and is operated by the Manager, a commodity pool operator registered with the CFTC. The Manager is an indirect subsidiary of Barclays Bank PLC. Barclays Global Fund Advisors, an indirect subsidiary of Barclays Bank
PLC, serves as the commodity trading advisor of the Investing Pool and is registered with the CFTC.

The Investing Pool is not an
investment company registered under the Investment Company Act of 1940, as amended.

2  Summary of Significant Accounting Policies

A. Basis of Accounting

The
accompanying financial statements have been prepared in conformity with U.S. GAAP. The preparation of financial statements in conformity with U.S. GAAP requires management to make certain estimates and assumptions that affect the reported amounts of
assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates and these differences could be material.

B. Investment in CERFs

CERFs are
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 S&P GSCI-ER at that time. The terms of the CERFs require the Investing Pool to deposit
initial margin with a value equal to 100% of the value of each CERF position at the time the position is established, thereby making those positions unleveraged. Because of this, additional variation margin payments are not required. Although daily
variation margins are not required, daily fluctuations in the value of the CERFs are recorded as unrealized gain or loss. When a CERF is closed, the Investing Pool records a realized gain or loss based on the difference between the value of the CERF
at the time it was opened and the value at the time it was closed. The Investing Pool will deposit with the clearing futures commission merchant the required margin for the CERFs in the form of cash or Short-Term Securities.

CERFs are derivative instruments valued at fair value in accordance with Financial Accounting Standards Statement No. 133, Accounting for
Derivative Instruments and Hedging Activities,which the Manager has determined to be that days announced CME settlement price for the CERF. If there is no announced CME settlement price for the CERF on that day, the Manager will use the
most recently announced CME settlement price unless the Manager determines that the price is inappropriate as a basis for the valuation of the CERFs.

C. Cash and Cash Equivalents

The Investing Pool defines cash and cash equivalents to be highly liquid investments with original maturities of three months or less.

D. Short-Term Investments

Short-term
investments on the statement of financial condition consist principally of short-term fixed income securities with original maturities of one year or less. These investments are valued at fair value.

E. Securities Transactions, Income and Expense Recognition

Securities transactions are accounted for on the trade date. Realized gains and losses on investment transactions are determined using the specific identification method. Other income and expenses are recognized on
the accrual basis.

F. Income Taxes

The Investing Pool is not an association taxable as a corporation and is treated as a partnership for federal, state and local income tax purposes.

No provision for federal, state, and local income taxes has been made in the accompanying financial statements because the Investing Pool is not subject
to income taxes. Holders of interests in the Investing Pool are individually responsible for their own tax payments on their proportionate share of gains, losses, credits, or deductions.

G. Calculation of Net Asset Value

The net asset value of the Investing Pool on any given day is obtained by subtracting the Investing Pools accrued expenses and other liabilities on that day from the value of the assets of the Investing Pool, calculated as of 4:15
p.m., New York City time, on each day on which NYSE Arca is open for regular trading, as soon as practicable after that time.

3  Offering of the
Investing Pool Interests

Investing Pool Interests are issued only to and
redeemable only by the iShares® S&P GSCI Commodity-Indexed Trust (the Trust) in exchange for a combination of
CERFs and cash or Short-Term Securities in lieu of cash. The baskets of CERFs and cash or Short-Term Securities in lieu of cash are transferred to or from the Trust in exchange for interests in the Investing Pool. Individual investors cannot
purchase or redeem Investing Pool Interests. The Investing Pool transacts only with the Trust and the Manager.

Redemptions of Investing
Pool Interests in exchange for CERFs and cash or Short-Term Securities in lieu of cash are treated as sales for financial statement purposes.

4 
Investing Pool Expenses

The Manager pays the amounts that would otherwise be considered the ordinary operating expenses, if any, of the
Investing Pool. The Manager receives an allocation from the Investing Pool that accrues daily at an annualized rate equal to 0.75% of the net asset value of the Investing Pool.

5  Related Parties

Barclays Global Investors International, Inc. is the Manager of the Investing Pool, and Barclays Global Investors, N.A. is the Administrator of the Investing Pool. The Manager and the
Administrator are considered to be related parties to the Trust and Investing Pool.

6  Indemnification

The Trust, the Manager and any officers, agents and delegates of the Investing Pool (the Indemnitees) are entitled to indemnification from the
Investing Pool for any loss, damage, claim or expense (including reasonable attorneys fees) incurred by any Indemnitee by reason of any act or omission performed or omitted by such Indemnitee on behalf of the Investing Pool, unless such act or
omission is the result of such Indemnitees gross negligence, bad faith or willful misconduct, and provided that such indemnity shall be provided out of, and only to the extent of, the Investing Pools assets.

7  Commitments and Contingent Liabilities

In
the normal course of business, the Investing Pool may enter into contracts with service providers that contain general indemnification clauses. The Investing Pools maximum exposure under these arrangements is unknown as this would involve
future claims that may be made against the Investing Pool that have not yet been made.

8  Financial Highlights

The Investing Pool is presenting the following financial highlights related to investment performance and operations for the years ended December 31,
2008 and 2007 and the period from July 10, 2006 (commencement of operations) to December 31, 2006. The net investment income and total expense ratios are calculated using average net assets. The net investment income and expense ratios for
the period from July 10, 2006 (commencement of operations) to December 31, 2006 have been annualized. The total return is based on the change in the net asset value during the period.

9  Investing in CERFs

Substantially all of the Investing Pools assets are invested in CERFs. The CERFs settlement value at expiration is based on the value of the S&P GSCI-ER at that time. Therefore, the value of the
Investing Pool will fluctuate based upon the value of the S&P GSCI-ER and the prices of the commodities underlying the S&P GSCI-ER. The commodities markets have historically been extremely volatile.

As of December 31, 2008, the open CERFs were as follows:



|          |  |                 |  |                 |             |                     |   |              |  
|--------- |  | --------------- |  | --------------- | ----------- | ------------------- | - | ------------ | -
|Contracts |  | Expiration Date |  | Notional Amount |             | Net Unrealized Loss |  
|12,122    |  | March 2011      |  | $               | 463,666,500 |                     | $ | (332,006,630 | )

As of December 31, 2007, the open CERFs were as follows:



|          |  |                 |  |                 |             |                     |   |           
|--------- |  | --------------- |  | --------------- | ----------- | ------------------- | - | ----------
|Contracts |  | Expiration Date |  | Notional Amount |             | Net Unrealized Gain
|6,177     |  | March 2011      |  | $               | 457,345,080 |                     | $ | 69,250,140

10  Investment Valuation

Effective January 1, 2008, the Investing Pool adopted Financial Accounting Standards Board (FASB) Statement of Financial Accounting Standards
No. 157 (FAS 157), Fair Value Measurements. This standard establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. Inputs may be based on independent market data
(observable inputs) or they may be internally developed (unobservable inputs). The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements)
and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy under FAS 157 are as follows:



|        |  |   |  |                                                                                                                                                                                                        
|------- |  | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
|Level 1 |  |  |  | Inputs that reflect unadjusted quoted prices in active markets for identical assets or liabilities that the Investing Pool has the ability to access as of the measurement
date;                       
|Level 2 |  |  |  | Inputs other than quoted prices included within Level 1 that are observable for the asset or liability either directly or indirectly, including inputs in markets that are not considered to be
active;
|Level 3 |  |  |  | Inputs that are unobservable for the asset or liability.                                                                                                                                               

The investment in CERFs is measured at fair value using the CME settlement price for CERFs. CERFs
are classified as a Level 1 security,as the CME settlement price is a quoted price for an identical asset in an active market. At December 31, 2008, the fair value of CERFs equaled $463,666,500.

The terms of the CERFs require the Investing Pool to deposit initial margin with a value equal to 100% of the value of each CERF position at the time the
position is established, thereby making those positions unleveraged. This margin collateral, in the form of short-term investments in Treasury bills, is valued at fair value. Under FAS 157, the Treasury bills are classified as a Level 1
security, as there is a quoted price for an identical asset in an active market. At December 31, 2008, the fair value of short-term investments equaled $419,578,033.

11  Current Accounting Developments

In March 2008, the Financial Accounting Standards Board
issued Financial Accounting Standards Statement No. 161, Disclosures about Derivative Instruments and Hedging Activities, an amendment of FASB Statement No. 133 (FAS 161). FAS 161 enhances the disclosures for derivative
instruments and hedging activities. The statement is effective for fiscal years and interim periods beginning after November 15, 2008. The Trust and Investing Pool are currently evaluating the impact that FAS 161 may have on their financial
statements.
