Part I

Item 1. Business.

Summary

The iShares® S&P GSCITMCommodity-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 GSCITMCommodity-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 GSCITMExcess 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 GSCITMTotal 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.

BlackRock Asset Management International
Inc. (formerly Barclays Global Investors International Inc.), or BAMII, is the Sponsor of the Trust and the Manager of the Investing Pool. BlackRock Institutional Trust Company, N.A. (formerly Barclays Global Investors,
N.A.), or BTC, is the Trustee of the Trust. The Trust and the Investing Pool are commodity pools, as defined in the regulations of the Commodity Futures Trading Commission, or CFTC, and are operated by BAMII, 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:



| | (1) | issuing Investing Pool Interests to the Trust in return for CERFs and cash or Short-Term Securities,
| | --- | ----------------------------------------------------------------------------------------------------



| | (2) | paying out of Investing Pool assets any expenses and liabilities not assumed by the Manager, and
| | --- | ------------------------------------------------------------------------------------------------



| | (3) | delivering proceeds consisting of CERFs, cash and Short-Term Securities in exchange for Investing Pool Interests surrendered for redemption.
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------

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.

BlackRock Fund Advisors (formerly 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 CERFs trading on the CME and for the underlying
commodities in the S&P GSCI-ER will be reduced whenever the principal markets for these contracts are closed, which usually occurs 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



2



---

##### Table of Contents

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.

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,
| | --- | ---------------------------



| | (4) | audit fees,

| | --- | --------------------



| | (6) | license fees and
| | --- | ----------------



| | (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, BAMII 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 $9,015,519 for the year ended December 31, 2009.

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.

##### Table of Contents

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.
| | - |  | -----------------------------------

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 Depository Trust Company, or 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 BAMII, as members. BAMII 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 BTC, 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. BTC 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 BAMII
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 (FCM) 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 FCMs 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 GSCITM, 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 GSCITMfutures contracts and options on futures contracts. CERFs are subject to the rules of the CME. The number of Shares the Trust is able to have outstanding at any time is dependent on the number of CERFs the Investing Pool is permitted to
own under the rules of the CME, which impose limits or accountability standards with respect to the maximum number of CERFs that a market participant may own.

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 FCM acting as its agent. Under these clearing arrangements, the CME Clearing House becomes the buyer to each member FCM representing a seller of the contract and the seller to each member FCM representing a buyer of the contract. As a
result of these clearing arrangements, each trader holding a position in CERFs is subject to the credit risk of the CME Clearing House and the FCM carrying its position in CERFs.

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 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 FCM initial margin in an amount equal to 100% of the value of the CERF on the date the position is established. The FCM, in turn, 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 CME 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 FCM as variation margin if the value of the CERFs declines. Instead, the FCM is obligated to make
variation margin payments to the CME Clearing House 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 FCM receives variation margin from the CME Clearing House 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 FCM 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 FCM its initial margin deposit, adjusted for variation margin paid or received by the FCM with respect to the
contract during the time it was held by the participant (or the proceeds from liquidation of any investments made with such funds for the benefit of the participant under the terms of its custody arrangement with the carrying FCM).

The 100% margin participants 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 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.

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 five full-time professional members of S&Ps staff. 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. Both S&P and Goldman Sachs are represented on the Index Advisory Panel. Certain of the members of the Index Advisory Panel may be affiliated with clients of S&P. Also, certain of the members of the Index Advisory Panel
may be affiliated with entities which, from time to time, may have investments linked to the S&P GSCI, either through transactions in the contracts included in the S&P GSCI, futures contracts on the S&P GSCI or
derivative products linked to 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 dividing (A) the product of the contract production weight of each contract, or CPW, and the average of its daily contract reference prices on the last day of each month during the relevant period, by (B) the sum of the products in
(A) for all contracts included in the S&P GSCI. The CPW of a contract is part of 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 one and a half 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



12



---

##### Table of Contents

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
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 weights of each of the underlying commodities.

The dollar weight of each such commodity on any given day is equal to:



| |  |  | the daily contract reference price;
| | - |  | -----------------------------------



| |  |  | multiplied by the appropriate CPW; and
| | - |  | --------------------------------------



| |  |  | during a roll period, the appropriate roll weights (discussed below).
| | - |  | -----------------------------------------------------------------------

The daily contract reference price used in calculating the dollar weight of each commodity on any given day is the most recent daily contract reference
price made available by the relevant trading facility, except that the daily contract reference price for the most recent prior day will be used if the exchange is closed or otherwise fails to publish a daily contract reference price on that day. In
addition, if the trading facility fails to make a daily contract reference price available or publishes a daily contract reference price that, in the reasonable judgment of the Index Sponsor, reflects manifest error, the relevant calculation will be
delayed until the price is made available or corrected; provided, that, if the price is not made available or corrected by 4:00 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.
| | - |  | --------------------------------------------------------------------------------

##### Table of Contents

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, transporting and storing commodities, changes in consumer or commercial 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, global economic factors, and government intervention in or regulation of the commodity or commodity futures
markets. 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.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Significant reductions in the size of positions permitted to be owned by the Investing Pool or others in CERFs or in the futures contracts and/or
commodities comprising the S&P GSCI, for example as a result of more restrictive position limits or position limit exemptions, could reduce liquidity and depress the price of the S&P GSCI and/or the underlying commodities,
adversely affecting the value of your 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 2009 may specify a December 2009 expiration. As that contract nears expiration, it may be replaced by selling the December 2009 contract and purchasing the contract expiring in March 2010. 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 2009 contract would take place at a price that is higher than the
price at which the March 2010 contract is purchased, thereby allowing the contract holder to purchase a greater quantity of the March 2010 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 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 futures and over-the-counter derivatives positions; transferring from U.S. futures exchanges to the CFTC the
authority to establish certain speculative position limits; imposing aggregate speculative position limits across regulated futures, over-the-counter positions and certain contracts traded on non-U.S. exchanges; 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.

The CFTC has also recently proposed regulations that would impose new federal speculative position limits on futures and
option contracts on certain energy commodities, in addition to the limits and accountability levels currently set by U.S. futures exchanges. The proposed regulations, in their current form, would apply such federal energy position limits to
institutional index funds in the same manner as such limits are applied to traditional speculative investors, and would restrict institutional index funds from continuing to rely on existing exchange risk management
exemptions once their positions reach the higher level of the new federal limits. The proposed regulations would also impose position limits based on the percentage of open interest a traders positions represents.

Although the proposed federal energy position limits would not generally apply to futures and option contracts based on diversified commodity
indexes such as CERFs, the CFTC has requested comment on the application of position limits and position limit exemptions to index funds and it is impossible to predict whether the proposed regulations will be adopted in their current form, or
whether other federal speculative position limits applicable to CERFS, or modifications to existing exchange position limits, may be adopted in the future. The possibility cannot be excluded, however, that future regulatory action by the CFTC will
further restrict the maximum number of CERFs that the Investing Pool will be permitted to own. See also Risk FactorsExchange position limits and other rules may restrict the creation of Baskets and the operation of 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 also affect liquidity in the market for the CERFs and the correlation between the price of the Shares and the
net asset value of the Trust. It is impossible 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.

##### Table of Contents

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
Commodity Exchange Act of 1936, as amended, 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 indices has changed.

Goldman, Sachs & Co., the previous Index Sponsor, sold its interest in the GSCI family of indices, 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.

##### Table of Contents

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 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 FCM must segregate customers assets. If a FCM 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.

##### Table of Contents

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 FCM, 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 FCM or clearing
house if the customer property held by the FCM 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.

the Shares particularly or the ability of the S&P GSCI, the S&P GSCI-ER or the Index, including, without limitation, all sub-indices, to track the appropriate market performance. The Index Sponsors only relationship to BAMII,
BTC, 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
composed by the Index Sponsor and calculated by the Index Sponsor or its agents without regard to BAMII, BTC, the Trust or the Investing Pool. The Index Sponsor has no obligation to take the needs of BAMII, BTC, the Trust, the Investing Pool or the
Shareholders into consideration in determining, composing or calculating the S&P GSCI, the S&P GSCI-ER or the Index. The Index Sponsor is not responsible for and has not participated in the determination of the prices and the number of

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.

##### Table of Contents

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 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.



21



---

##### Table of Contents

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 risk management exemption from these position limits that should permit the Investing Pool to
hold up to 40,000 contracts until December 31, 2010. 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
reduce its position limits applicable to CERFs and/or 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. See also Risk Factors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.

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. See also Risk Factors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.

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. BAMII, as the Sponsor and the
Manager, is registered with the CFTC as a commodity pool operator, and BlackRock 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.



23



---

##### Table of Contents

While the Sponsor 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, exchange 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.
See also Risk Factors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.

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.

##### Table of Contents

In return for paying certain amounts that would otherwise be considered ordinary operating expenses of the
Trust and 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 and is payable monthly in arrears. The allocation received
by the Manager from the Investing Pool may be higher than the amount the Investing Pool would negotiate with an unaffiliated third party manager on an arms-length basis.

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



25



---

##### Table of Contents

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.

The number of Shareholders of record
of the registrant as of January 29, 2010 was approximately 149.

The Trust made no distributions to Shareholders during the fiscal years
ended December 31, 2009 and 2008. 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) 8 Baskets (400,000 Shares) were redeemed during the fourth quarter of the year ended December 31, 2009.

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, 2009 (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
$1,759,350,446 at December 31, 2009. Outstanding Shares in the Trust grew from 150,000 Shares at July 10, 2006 to 55,550,000 Shares outstanding at December 31, 2009.

Results of Operations

The year ended December 31, 2009

Net Asset Value of the Trust

The Trusts net asset value grew from $466,237,257 at December 31, 2008 to $1,759,350,446. The increase in the Trusts net asset value
resulted primarily from an increase in outstanding Shares, which rose from 16,950,000 at December 31, 2008 to 55,550,000 at December 31, 2009 due to 40,350,000 Shares (807 Baskets) being created and 1,750,000 Shares (35
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, 2009, which the price increased from $382.50 per CERF to $442.70 per CERF,
a 15.74% increase.

The year ended December 31, 2008

Net Asset Value of the 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 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 the 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.

Liquidity and Capital
Resources

The Trusts sole asset as of December 31, 2009 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, 2009, interest income was $2,377,320, while the fixed fee totaled $9,015,519. 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. For the year ended December 31, 2009, the fixed fee
comprised a greater proportion of interest income than the proportion applicable to the year ended December 31, 2008. 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 and/or insufficient interest
income to cover ordinary expenses, 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
Clearing House, 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 Clearing
House.

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.

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, 2009, the Investing Pools open CERF positions (long) were as follows:



|                                    |  |   |              
|----------------------------------- |  | - | -------------
|Number of Contracts                 |  |   | 39,582       
|Expiration Date                     |  |   | March 2011   
|Weighted-Average Price per Contract |  | $ | 471.30       
|Fair Value                          |  | $ | 1,752,295,140

Fair value is calculated
using the settlement price for the CERFs on the CME on December 31, 2009, which was $442.70 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, 2009. 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, 2009.

The effectiveness of the Trusts and Investing Pools internal control over financial reporting as of December 31, 2009 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, have 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, 2009 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,
2009 and 2008, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2009 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, 2009, 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 Managements Report on Internal Control over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on these financial statements and on the
Trusts internal control over financial reporting based on our integrated audits. 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, 2009

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. On December 1, 2009, the previously announced acquisition by BlackRock, Inc. of Barclays Global Investors International Inc., Barclays
Global Investors, N. A., Barclays Global Fund Advisors and certain of their affiliated companies was consummated. In connection with this change of ownership, entity names changed as follows: Barclays Global Investors International Inc. is now
BlackRock Asset Management International Inc.; Barclays Global Investors, N.A. is now BlackRock Institutional Trust Company, N.A.; and Barclays Global Fund Advisors is now BlackRock Fund Advisors. BlackRock Asset Management International Inc. is the
Sponsor of the Trust and Manager of the Investing Pool. BlackRock Institutional Trust Company, 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 regulations of the Commodity Futures Trading Commission, or CFTC, and are operated by BlackRock Asset Management International Inc., a commodity pool operator registered with the CFTC. BlackRock Asset Management
International Inc. is an indirect subsidiary of BlackRock, Inc.

The Trustee has the absolute right to reject any creation order, including,
without limitation, creation orders that the Trustee has determined would have adverse tax or other consequences to the Trust, its shareholders or the Investing Pool. The Trust disclosed through a report on Form 8-K, which was filed with the
Securities and Exchange Commission (the SEC) on August 21, 2009, that the Trustee expected to reject any creation orders for Shares of the Trust upon the Trust reaching Shares outstanding of approximately 55,900,000 in order to
continue to manage the assets of the Trust and the Investing Pool consistent with their investment objective. The Trust received creation orders on August 24, 2009 that would have exceeded that number of Shares, and has accordingly stopped
accepting further creation orders temporarily.

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 accounting principles generally accepted in the United States of America (U.S. GAAP). The preparation of financial statements in conformity



F-7

##### Table of Contents

iShares® S&P GSCI
Commodity-Indexed Trust

Notes to Financial Statements (Continued)

December 31, 2009



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, 2009, 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. 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 August 24, 2009, the Trust temporarily
stopped accepting creation orders for the Shares. See Note 1 above.

On December 31, 2009, the Trust had 55,550,000 Shares outstanding.

4 - Trust Expense

The Trust
is not expected to bear any ordinary recurring expenses. The Sponsor has agreed to pay the following administrative, operational and marketing expenses: (1) the fees of the Trustee, Delaware Trustee, Trust administrator and processing agent,
(2) NYSE Arca 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, 2009, 2008 and 2007. The net investment income and total expense ratios are calculated using average
net asset value. 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 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

The Trust values investments using 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 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, 2009 and 2008, the fair value of the Trusts interests in the Investing Pool equaled $1,759,350,446 and $466,237,257, respectively.

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.

10 - Review for Subsequent Events

In connection with the preparation of the financial statements of the Trust as of and for the period ended December 31, 2009, management has evaluated the impact of all subsequent events through the
date the financial statements were issued, and has determined that there were no subsequent events requiring adjustment or disclosure in the 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, 2009 and 2008, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2009 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, 2009, 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 Managements Report on Internal Control over Financial
Reporting appearing under Item 9A. 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 integrated
audits. 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.

Notes to Financial Statements

December 31, 2009

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. On December 1, 2009, the previously announced acquisition by BlackRock, Inc. of Barclays Global Investors International Inc., Barclays Global Investors, N. A., Barclays Global Fund Advisors and certain of their affiliated
companies was consummated. In connection with this change of ownership, entity names changed as follows: Barclays Global Investors International Inc. is now BlackRock Asset Management International Inc.; Barclays Global Investors, N.A. is now
BlackRock Institutional Trust Company, N.A.; and Barclays Global Fund Advisors is now BlackRock Fund Advisors. BlackRock Asset Management 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
regulations of the Commodity Futures Trading Commission, or CFTC, and is operated by the Manager, a commodity pool operator registered with the CFTC. The Manager is an indirect subsidiary of BlackRock, Inc. BlackRock Fund Advisors, an
indirect subsidiary of BlackRock, Inc., 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 accounting principles generally accepted in the United States of America (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, 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. The Investing Pools investment in the CERFS has not been designated as a hedging instrument. As a result, all changes in the fair value are reflected in the Statement of Operations.

The investment objective of the Investing Pool is to seek investment results that correspond generally to the performance of the Index before
payment of the Investing Pools expenses through holdings of long positions in CERFs.

For futures contracts, counterparty credit risk is
mitigated because futures contracts are exchange-traded and the exchanges clearing house acts as central counterparty to all exchange-traded futures contracts (although customers continue to have credit exposure to the clearing member who
holds their account).

Please refer to Note 9 for additional disclosures regarding the Trusts investments in 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

Interests in the Investing Pool (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 Investing Pool Interests. 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

BlackRock Asset Management International Inc. is the Manager of the Investing Pool, and BlackRock Institutional Trust Company, 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.

The Investing Pool is presenting the following financial highlights related to investment performance and operations for the years ended December 31, 2009, 2008 and 2007. The net investment income

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. For the year ended December 31, 2009, the average daily notional amount of open CERFs was $834,485,360.

As of December 31, 2009, the open CERFs were as follows:



|          |  |                 |  |                         |               |                     |   |              |

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



|          |  |                 |  |                         |             |                     |   |              |

10 - Investment Valuation

The Investing Pool values investments using 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 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, 2009 and 2008, the fair value of CERFs equaled $1,752,295,140 and $463,666,500, respectively.

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. The Treasury bills are classified as a Level 2 security, as quoted prices for an identical asset are obtained from markets that are generally less active. At December 31, 2009
and 2008, the fair value of short-term investments equaled $1,722,340,589 and $419,578,033, respectively.

11 - Review for Subsequent
Events

In connection with the preparation of the financial statements of the Investing Pool as of and for the period ended
December 31, 2009, management has evaluated the impact of all subsequent events through the date the financial statements were issued, and has determined that there were no subsequent events requiring adjustment or disclosure in the financial
statements.
