** As of March 1, 2007, ordinary operating expenses of the Trust accrue at approximately 0.1663%. As of the fiscal year ended October 31, 2006, ordinary operating expenses of the Trust were 0.1768%, and after excess balance credits of 0.0064% were applied, net expenses of the Trust were 0.1704%.

The amount of the earnings credit will be equal to the Federal Funds Rate,  as reported in nationally distributed publications, multiplied by each day’s  daily cash balance in the Trust’s cash account, reduced by the amount of reserves  for that account required by the Federal Reserve Board of Governors. The Sponsor has undertaken that the ordinary operating expenses of the Trust will not exceed an amount that is 0.1800% of the daily NAV of the Trust, but this amount may be changed. Therefore, there is no guarantee that the Trust’s ordinary operating expenses will not exceed the current 0.1663% or 0.1800% of the Trust’s daily NAV.

Highlights

•  DIAMONDS are Ownership Interests in the DIAMONDS Trust

DIAMONDS Trust, Series 1 (‘‘Trust’’) is a unit investment trust that issues securities called ‘‘DIAMONDS’’. The Trust is organized under New York law and is governed by a trust agreement between State Street Bank and Trust Company (‘‘Trustee’’) and PDR Services LLC (‘‘Sponsor’’), dated and executed as of January 13, 1998 (‘‘Trust Agreement’’). The Trust is an investment company registered under the Investment Company Act of 1940. DIAMONDS represent an undivided ownership interest in a portfolio of all of the common stocks of the Dow Jones Industrial Average (‘‘DJIA’’).

•  DIAMONDS Should Closely Track the Value of the Stocks Included in the DJIA

DIAMONDS intend to provide investment results that, before expenses, generally correspond to the price and yield performance of the DJIA. Current information regarding the value of the DJIA is available from market information services. Dow Jones obtains information for inclusion in, or for use in the calculation of, the DJIA from sources Dow Jones considers reliable. None of Dow Jones, the Sponsor, the Trust or the Exchange accepts responsibility for or guarantees the accuracy and/or completeness of the DJIA or any data included in the DJIA.

The Trust holds the Portfolio and cash and is not actively ‘‘managed’’ by traditional methods, which typically involve effecting changes in the Portfolio on the basis of judgments made relating to economic, financial and market considerations. To maintain the correspondence between the composition and weightings of stocks held by the Trust (‘‘Portfolio Securities’’ or, collectively, ‘‘Portfolio’’) and component stocks of the DJIA (‘‘Index Securities’’), the Trustee adjusts the Portfolio from time to time to conform to periodic changes in the identity and/or relative weightings of Index Securities. The Trustee generally makes these adjustments to the Portfolio within three (3) Business Days (defined below) before or after the day on which changes in the DJIA are scheduled to take effect. Any change in the identity or weighting of an Index Security will result in a corresponding adjustment to the prescribed Portfolio Deposit effective on any day that the New York Stock Exchange, LLC (‘‘NYSE’’) is open for business (‘‘Business Day’’) following the day on which the change to the DJIA takes effect after the close of the market.

The value of DIAMONDS fluctuates in relation to changes in the value of the Portfolio. The market price of each individual DIAMONDS may not be identical to the net asset value (‘‘NAV’’) of such DIAMONDS but, historically, these two valuations have been very close.

•  DIAMONDS Trade on the American Stock Exchange

DIAMONDS are listed for trading on the American Stock Exchange (‘‘Exchange’’ or ‘‘AMEX’’), and are bought and sold in the secondary market

3




like ordinary shares of stock at any time during the trading day. DIAMONDS are traded on the Exchange in 100 DIAMOND round lots, but can be traded in odd lots of as little as one DIAMOND. The Exchange may halt trading of DIAMONDS under certain circumstances.

•  Brokerage Commissions on DIAMONDS

Secondary market purchases and sales of DIAMONDS are subject to ordinary brokerage commissions and charges.

•  The Trust Issues and Redeems DIAMONDS in Multiples of 50,000 DIAMONDS Called ‘‘Creation Units’’

The Trust issues and redeems DIAMONDS only in specified large lots of 50,000 DIAMONDS or multiples thereof referred to as ‘‘Creation Units.’’ Fractional Creation Units may be created or redeemed only in limited circumstances. *

Creation Units are issued by the Trust to anyone who, after placing a creation order with ALPS Distributors, Inc. (‘‘Distributor’’), deposits with the Trustee a specified portfolio of Index Securities and a cash payment generally equal to dividends (net of expenses) accumulated up to the time of deposit. If the Trustee determines that one or more Index Securities are likely to be unavailable, or available in insufficient quantity, for delivery upon creation of Creation Units, the Trustee may permit the cash equivalent value of one or more of these Index Securities to be included in the Portfolio Deposit as a part of the Cash Component in lieu thereof. If a creator is restricted by regulation or otherwise from investing or engaging in a transaction in one or more Index Securities, the Trustee may permit the cash equivalent value of such Index Securities to be included in the Portfolio Deposit based on the market value of such Index Securities as of the Evaluation Time on the date such creation order is deemed received by the Distributor as part of the Cash Component in lieu of the inclusion of such Index Securities in the stock portion of the Portfolio Deposit.

Creation Units are redeemable in kind only and are not redeemable for cash. Upon receipt of one or more Creation Units, the Trust delivers to the redeeming holder a portfolio of Index Securities (based on NAV of the Trust), together with a cash payment. Each redemption has to be accompanied by a Cash Redemption Payment that on any given Business Day is an amount identical to the Cash Component of a Portfolio Deposit. If the Trustee determines that one or more Index Securities are likely to be unavailable or available in insufficient quantity for delivery by the Trust upon the redemption

* See the discussion of termination of the Trust in this Summary and ‘‘Dividend Reinvestment Service’’ for a description of the circumstances in which DIAMONDS may be redeemed or created by the Trustee in less than a Creation Unit size aggregation of 50,000 DIAMONDS.

4




of Creation Units, the Trustee may deliver the cash equivalent value of one or more of these Index Securities, based on their market value as of the Evaluation Time on the date the redemption order is deemed received by the Trustee, as part of the Cash Redemption Payment in lieu thereof.

•  Creation Orders Must be Placed with the Distributor

All orders to create Creation Units must be placed with the Distributor. To be eligible to place these orders, an entity or person must be (a) a ‘‘Participating Party,’’ or (b) a DTC Participant, and in each case must have executed an agreement with the Distributor and the Trustee (‘‘Participant Agreement’’). The term ‘‘Participating Party’’ means a broker-dealer or other participant in the DIAMONDS Clearing Process, through the Continuous Net Settlement (‘‘CNS’’) System of the National Securities Clearing Corporation (‘‘NSCC’’), a clearing agency registered with the Securities and Exchange Commission (‘‘SEC’’). Payment for orders is made by deposits with the Trustee of a portfolio of securities, substantially similar in composition and weighting to Index Securities, and a cash payment in an amount equal to the Dividend Equivalent Payment, plus or minus the Balancing Amount. ‘‘Dividend Equivalent Payment’’ is an amount equal, on a per Creation Unit basis, to the dividends on the Portfolio (with ex-dividend dates within the accumulation period), net of expenses and accrued liabilities for such period (including, without limitation, (i) taxes or other governmental charges against the Trust not previously deducted, if any, and (ii) accrued fees of the Trustee and other expenses of the Trust (including legal and auditing expenses) and other expenses not previously deducted), calculated as if all of the Portfolio Securities had been held for the entire accumulation period for such distribution. The Dividend Equivalent Payment and the Balancing Amount collectively are referred to as ‘‘Cash Component’’ and the deposit of a portfolio of securities and the Cash Component collectively are referred to as a ‘‘Portfolio Deposit.’’ Persons placing creation orders with the Distributor must deposit Portfolio Deposits either (i) through the CNS clearing process of NSCC, as such processes have been enhanced to effect creations and redemptions of Creation Units, such processes referred to herein as the ‘‘DIAMONDS Clearing Process,’’ or (ii) with the Trustee outside the DIAMONDS Clearing Process (i.e., through the facilities of DTC).

The Distributor acts as underwriter of DIAMONDS on an agency basis. The Distributor maintains records of the orders placed with it and the confirmations of acceptance and furnishes to those placing such orders confirmations of acceptance of the orders. The Distributor also is responsible for delivering a prospectus to persons creating DIAMONDS. The Distributor also maintains a record of the delivery instructions in response to orders and may provide certain other administrative services, such as those related to state securities law compliance. The Distributor is a corporation organized under the laws of the State of Colorado and is located at 1625 Broadway, Suite 2200,

5




Denver, CO 80202, toll free number: 1-800-843-2639. The Distributor is a registered broker-dealer and a member of the National Association of Securities Dealers, Inc. The Sponsor of the Trust pays the Distributor for its services a flat annual fee. The Sponsor will not seek reimbursement for such payment from the Trust without obtaining prior exemptive relief from the SEC.

•  Expenses of the Trust

The expenses of the Trust are accrued daily and reflected in the NAV of the Trust. After reflecting waivers but before reflecting credits, the Trust currently is accruing ordinary operating expenses at an annual rate of 0.1768%.


Shareholder Fees:* None*
(fees paid directly from your investment)
Estimated Trust Annual Ordinary Operating Expenses:

Current Trust Annual Ordinary
Operating Expenses
As a % of
Trust Net Assets
Trustee’s Fee   0.0701
Trustee Reduction for Earnings Credits**   (0.0106 )% 
Dow Jones License Fee   0.0393
Registration Fees   0.0000
Marketing   0.0600
Other Operating Expenses   0.0075
Net Expenses**   0.1663

Future expense accruals will depend primarily on the level of the Trust’s net assets and the level of expenses.

* Investors do not pay shareholder fees directly from their investment, but purchases and redemptions of Creation Units are subject to Transaction Fees (described below in ‘‘A Transaction Fee is Payable For Each Creation and For Each Redemption of Creation Units’’), and purchases and sales of DIAMONDS in the secondary market are subject to ordinary brokerage commissions and charges (described above in ‘‘Brokerage Commissions on DIAMONDS’’).
** Until the Sponsor otherwise determines, the Sponsor has undertaken that the ordinary operating expenses of the Trust will not be permitted to exceed 0.1800% of the Trust’s daily NAV. Gross expenses of the Trust for the year ending October 31, 2006, without regard to this undertaking, were 0.1768% of the daily NAV of the Trust and therefore no expenses of the Trust were assumed by the Sponsor. The Sponsor reserves the right to discontinue this undertaking in the future. Therefore, there is no guarantee that the Trust’s ordinary operating expenses will not exceed 0.1800% of the Trust’s daily NAV. Trust expenses were reduced during the same period by a Trustee’s earnings credit of 0.0064% of the Trust’s daily NAV as a result of uninvested cash balances in the Trust. The amount of earnings credit will be equal to the Federal Funds Rate, as reported in nationally distributed publications, multiplied by each day’s daily cash balance in the Trust’s cash account, reduced by the amount of reserves for that account required by the Federal Reserve Board of Governors.

•  Bar Chart and Table

The bar chart below and the table on the next page entitled ‘‘Average Annual Total Returns (For Periods Ending December 31, 2006)’’ (‘‘Table’’) provide some indication of the risks of investing in the Trust by showing the variability of the Trust’s returns based on net assets and comparing the Trust’s performance to the performance of the DJIA. Past performance (both before and after tax) is not necessarily an indication of how the Trust will perform in the future.

The after-tax returns presented in the Table are calculated using the highest historical individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Your actual after-tax returns will depend on your specific tax situation and may differ from those shown below. After-tax returns are not relevant to investors who hold DIAMONDS through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts. The total returns in the bar chart below, as well as the total and after-tax returns presented in the Table, do not reflect Transaction Fees payable by those persons purchasing and redeeming Creation Units, nor brokerage commissions incurred by those persons purchasing and selling DIAMONDS in the secondary market (see footnotes (2) and (3) to the Table).

This bar chart shows the performance of the Trust for each full calendar year since its inception on January 13, 1998. During the period shown above (January 1, 1999 through December 31, 2006), the highest quarterly return for the Trust was 13.75% for the quarter ended 12/31/2001, and the lowest was −17.44% for the quarter ended 9/30/2002.

•  A Transaction Fee is Payable for Each Creation and for Each Redemption of Creation Units

The transaction fee payable to the Trustee in connection with each creation and redemption of Creation Units made through the DIAMONDS Clearing Process (‘‘Transaction Fee’’) is non-refundable, regardless of the NAV of the Trust. This Transaction Fee is $1,000 per Participating Party per day, regardless of the number of Creation Units created or redeemed on such day. The $1,000 charge is subject to a limit not to exceed 10/100 of one percent (10 basis points) of the value of one Creation Unit at the time of creation (‘‘10 Basis Point Limit’’).

For creations and redemptions outside the DIAMONDS Clearing Process, an additional amount not to exceed three (3) times the Transaction Fee applicable for one Creation Unit is charged per Creation Unit per day. Under the current schedule, therefore, the total fee charged in connection with creation or redemption outside the DIAMONDS Clearing Process would be $1,000 (the Transaction Fee for the creation or redemption of one Creation Unit) plus an additional amount up to $3,000 (3 times $1,000), for a total not to exceed $4,000. Creators and redeemers restricted from engaging in transactions in one or more Index Securities may pay the Trustee the Transaction Fee and may pay an additional amount per Creation Unit not to exceed three (3) times the Transaction Fee applicable for one Creation Unit.

•  DIAMONDS are Held in Book Entry Form Only

The Depository Trust Company (‘‘DTC’’) or its nominee is the record or registered owner of all outstanding DIAMONDS. Beneficial ownership of DIAMONDS is shown on the records of DTC or its participants. Individual certificates are not issued for DIAMONDS. See ‘‘The Trust—Securities Depository; Book-Entry-Only System.’’

•  DIAMONDS Make Periodic Dividend Payments

DIAMONDS holders receive each calendar month an amount corresponding to the amount of any cash dividends declared on the Portfolio Securities during the applicable period, net of fees and expenses associated with operation of the Trust, and taxes, if applicable. Because of such fees and expenses, the dividend yield for DIAMONDS is ordinarily less than that of the DJIA. Investors should consult their tax advisors regarding tax consequences associated with Trust dividends, as well as those associated with DIAMONDS sales or redemptions.

Monthly distributions based on the amount of dividends payable with respect to Portfolio Securities and other income received by the Trust, net of fees and expenses, and taxes, if applicable, are made via DTC and its participants to Beneficial Owners on each Dividend Payment Date. Any

9




capital gain income recognized by the Trust in any taxable year that is not previously treated as distributed during the year ordinarily is to be distributed at least annually in January of the following taxable year. The Trust may make additional distributions shortly after the end of the year in order to satisfy certain distribution requirements imposed by the Internal Revenue Code of 1986, as amended (‘‘Code’’). Although all income distributions are currently made monthly, the Trustee may vary the periodicity with which distributions are made. Those Beneficial Owners interested in reinvesting their monthly distributions may participate through DTC Participants in the DTC Dividend Reinvestment Service (‘‘Service’’) available through certain brokers. See ‘‘The Trust—Securities Depository; Book-Entry-Only System.’’

•  The Trust Intends to Qualify as a Regulated Investment Company

For the fiscal year ended October 31, 2006, the Trust believes that it qualified for tax treatment as a ‘‘regulated investment company’’ under Subchapter M of the Code. The Trust intends to continue to so qualify and to distribute annually its entire investment company taxable income and net capital gain. Distributions that are taxable as ordinary income to Beneficial Owners generally are expected to constitute dividend income for federal income tax purposes and to be eligible for the dividends-received deduction available to many corporations to the extent of qualifying dividend income received by the Trust. The Trust’s regular monthly distributions are based on the dividend performance of the Portfolio during such monthly distribution period rather than the actual taxable income of the Trust. As a result, a portion of the distributions of the Trust may be treated as a return of capital or a capital gain dividend for federal income tax purposes or the Trust may be required to make additional distributions to maintain its status as a regulated investment company or to avoid imposition of income or excise taxes on undistributed income.

•  Termination of the Trust

The Trust has a specified lifetime term. The Trust is scheduled to terminate on the first to occur of (a) January 13, 2123 or (b) the date 20 years after the death of the last survivor of fifteen persons named in the Trust Agreement, the oldest of whom was born in 1994 and the youngest of whom was born in 1997. Upon termination, the Trust may be liquidated and pro rata shares of the assets of the Trust, net of certain fees and expenses, distributed to holders of DIAMONDS.

•  Restrictions on Purchases of DIAMONDS by Investment Companies

Purchases of DIAMONDS by investment companies are subject to restrictions set forth in Section 12(d)(1) of the Investment Company Act of 1940. The Trust has received an SEC order that permits registered investment

10




companies to invest in DIAMONDS beyond these limits, subject to certain conditions and terms. One such condition is that registered investment companies relying on the order must enter into a written agreement with the Trust. Registered investment companies wishing to learn more about the order and the agreement should telephone 1-800-THE-AMEX.

The Trust itself is also subject to the restrictions of Section 12(d)(1). This means that (a) the Trust cannot invest in any registered investment company, to the extent that the Trust would own more than 3% of that regulated investment company’s outstanding share position, (b) the Trust cannot invest more than 5% of its total assets in the securities of any one registered investment company, and (c) the Trust cannot invest more than 10% of its total assets in the securities of registered investment companies in the aggregate.

Risk Factors

Investors can lose money by investing in DIAMONDS. Investors should carefully consider the risk factors described below together with all of the other information included in this Prospectus before deciding to invest in DIAMONDS.

Investment in the Trust involves the risks inherent in an investment in any equity security.    An investment in the Trust is subject to the risks of any investment in a portfolio of large-capitalization common stocks, including the risk that the general level of stock prices may decline, thereby adversely affecting the value of such investment. The value of Portfolio Securities may fluctuate in accordance with changes in the financial condition of the issuers of Portfolio Securities (particularly those that are heavily weighted in the DJIA), the value of common stocks generally and other factors. The identity and weighting of Index Securities and the Portfolio Securities also change from time to time.

The financial condition of the issuers may become impaired or the general condition of the stock market may deteriorate (either of which may cause a decrease in the value of the Portfolio and thus in the value of DIAMONDS). Common stocks are susceptible to general stock market fluctuations and to volatile increases and decreases in value as market confidence in and perceptions of their issuers change. These investor perceptions are based on various and unpredictable factors including expectations regarding government, economic, monetary and fiscal policies, inflation and interest rates, economic expansion or contraction, and global or regional political, economic and banking crises.

Holders of common stocks of any given issuer incur more risk than holders of preferred stocks and debt obligations of the issuer because the rights of common stockholders, as owners of the issuer, generally are inferior to the rights of creditors of, or holders of debt obligations or preferred stocks issued by, such issuer. Further, unlike debt securities that typically have a stated

11




principal amount payable at maturity, or preferred stocks that typically have a liquidation preference and may have stated optional or mandatory redemption provisions, common stocks have neither a fixed principal amount nor a maturity. Common stock values are subject to market fluctuations as long as the common stock remains outstanding. The value of the Portfolio may be expected to fluctuate over the entire life of the Trust.

There can be no assurance that the issuers of Portfolio Securities will pay dividends. Distributions generally depend upon the declaration of dividends by the issuers of Portfolio Securities and the declaration of such dividends generally depends upon various factors, including the financial condition of the issuers and general economic conditions.

The Trust is not actively managed.    The Trust is not actively ‘‘managed’’ by traditional methods, and therefore the adverse financial condition of an issuer will not result in the elimination of its stocks from the Portfolio unless the stocks of such issuer are removed from the DJIA.

A liquid trading market for certain Portfolio Securities may not exist. Although most of the Portfolio Securities are listed on a national securities exchange, the principal trading market for some may be in the over-the-counter market. The existence of a liquid trading market for certain Portfolio Securities may depend on whether dealers will make a market in such stocks. There can be no assurance that a market will be made for any Portfolio Securities, that any market will be maintained or that any such market will be or remain liquid. The price at which Portfolio Securities may be sold and the value of the Portfolio will be adversely affected if trading markets for Portfolio Securities are limited or absent.

The Trust may not always be able exactly to replicate the performance of the DJIA.    It is possible that, for a short period, the Trust may not fully replicate the performance of the DJIA due to the temporary unavailability of certain Index Securities in the secondary market or due to other extraordinary circumstances. In addition, the Trust is not able to replicate exactly the performance of the DJIA because the total return generated by the Portfolio is reduced by Trust expenses and transaction costs incurred in adjusting the actual balance of the Portfolio.

Investment in the Trust may have adverse tax consequences.    Investors in the Trust should also be aware that there are tax consequences associated with the ownership of DIAMONDS resulting from the distribution of Trust dividends and sales of DIAMONDS as well as under certain circumstances the sales of stocks held by the Trust in connection with redemptions.

NAV may not always correspond to market price.    The NAV of DIAMONDS in Creation Unit size aggregations and, proportionately, the NAV per DIAMONDS unit, changes as fluctuations occur in the market value of Portfolio Securities. Investors should be aware that the aggregate public

12




trading market price of 50,000 DIAMONDS may be different from the NAV of a Creation Unit (i.e., 50,000 DIAMONDS may trade at a premium over, or at a discount to, the NAV of a Creation Unit) and similarly the public trading market price per DIAMONDS unit may be different from the NAV of a Creation Unit on a per DIAMONDS unit basis. This price difference may be due, in large part, to the fact that supply and demand forces at work in the secondary trading market for DIAMONDS is closely related to, but not identical to, the same forces influencing the prices of Index Securities trading individually or in the aggregate at any point in time. Investors also should note that the size of the Trust in terms of total assets held may change substantially over time and from time to time as Creation Units are created and redeemed.

The Exchange may halt trading in DIAMONDS.    DIAMONDS are listed for trading on the Exchange under the market symbol DIA. Trading in DIAMONDS may be halted under certain circumstances, as set forth in the Exchange rules and procedures, that, in the view of the Exchange, make trading in DIAMONDS inadvisable. In addition, trading is subject to trading halts caused by extraordinary market volatility pursuant to Exchange ‘‘circuit breaker’’ rules that require trading to be halted for a specified period based on a specified market decline. The Exchange also must halt trading if required intraday valuation information is not disseminated for longer than one Business Day. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of DIAMONDS will continue to be met or will remain unchanged. The Trust will be terminated if DIAMONDS are delisted from the Exchange.

DIAMONDS are subject to market risks.    DIAMONDS are subject to the risks other than those inherent in an investment in equity securities, discussed above, in that the selection of the stocks included in the Portfolio, the expenses associated with the Trust, or other factors distinguishing an ownership interest in a trust from the direct ownership of a portfolio of stocks may affect trading in DIAMONDS.

Additionally, DIAMONDS may perform differently than other investments in portfolios containing large capitalization stocks based upon or derived from an index other than the DJIA. For example, the great majority of component stocks of the DJIA are drawn from among the largest of the large capitalization universe, while other indexes may represent a broader sampling of large capitalization stocks. Also, other indexes may use different methods for assigning relative weights to the index components than the price weighted method used by the DJIA. As a result, DJIA accords relatively more weight to stocks with a higher price to market capitalization ratio than a similar market capitalization weighted index.

The regular settlement period for Creation Units may be reduced.    Except as otherwise specifically noted, the time frames for delivery of stocks, cash, or DIAMONDS in connection with creation and redemption activity within the

13




DIAMONDS Clearing Process are based on NSCC’s current ‘‘regular way’’ settlement period of three (3) days during which NSCC is open for business (each such day an ‘‘NSCC Business Day’’). NSCC may, in the future, reduce such ‘‘regular way’’ settlement period, in which case there may be a corresponding reduction in settlement periods applicable to DIAMONDS creations and redemptions.

Clearing and settlement of Creation Units may be delayed or fail.    The Trustee delivers a portfolio of stocks for each Creation Unit delivered for redemption substantially identical in weighting and composition to the stock portion of a Portfolio Deposit as in effect on the date the request for redemption is deemed received by the Trustee. If redemption is processed through the DIAMONDS Clearing Process, the stocks that are not delivered are covered by NSCC’s guarantee of the completion of such delivery. Any stocks not received on settlement date are marked-to-market until delivery is completed. The Trust, to the extent it has not already done so, remains obligated to deliver the stocks to NSCC, and the market risk of any increase in the value of the stocks until delivery is made by the Trust to NSCC could adversely affect the NAV of the Trust. Investors should note that the stocks to be delivered to a redeemer submitting a redemption request outside of the DIAMONDS Clearing Process that are not delivered to such redeemer are not covered by NSCC’s guarantee of completion of delivery.

DIAMONDS Trust Series 1
Notes to Financial Statements
October 31, 2006

NOTE 1—ORGANIZATION

DIAMONDS Trust, Series 1 (the ‘‘Trust’’) is a unit investment trust created under the laws of the State of New York and registered under the Investment Company Act of 1940, as amended. The Trust was created to provide investors with the opportunity to purchase units of beneficial interest in the Trust representing proportionate undivided interests in the portfolio of securities consisting of substantially all of the component common stocks, which comprise the Dow Jones Industrial Average (the ‘‘DJIA’’). Each unit of fractional undivided interest in the Trust is referred to as a ‘‘DIAMOND’’. The Trust commenced operations on January 14, 1998 upon the initial issuance of 500,000 DIAMONDS (equivalent to ten ‘‘Creation Units’’ — see Note 4) in exchange for a portfolio of securities assembled to reflect the intended portfolio composition of the Trust.

NOTE 2—SIGNIFICANT ACCOUNTING POLICIES

The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that effect the reported amounts and disclosures in the financial statements. Actual results could differ from these estimates. The following is a summary of significant accounting policies followed by the Trust.

Security Valuation

Portfolio securities are valued based on the closing sale price on the exchange which is deemed to be the principal market for the security, except for securities listed on the NASDAQ which are valued at the NASDAQ official closing price. If there is no closing sale price available or official closing price, valuation will be determined by the Trustee in good faith based on available information.

In September, 2006, Statements of Financial Accounting Standards No. 157, Fair Value Measurements (‘‘SFAS 157’’), was issued and is effective for fiscal years beginning after November 15, 2007. SFAS 157 defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. Management is currently evaluating the impact, if any, the adoption of SFAS 157 will have on the Trust’s financial statements.

Investment Risk

The Trust invests in various investments which are exposed to risks, such as market risk. Due to the level of risk associated with certain investments it

is at least reasonably possible that changes in the values of investment securities will occur in the near term and that such changes could materially affect the amounts reported in the financial statements.

Investment Transactions

Investment transactions are recorded on the trade date. Realized gains and losses from the sale or disposition of securities are recorded on the identified cost basis. Dividend income is recorded on the ex-dividend date.

Distributions to Unitholders

The Trust declares and distributes dividends from net investment income to its unitholders monthly. The Trust will distribute net realized capital gains, if any, at least annually.

Equalization

The Trust follows the accounting practice known as ‘‘Equalization’’ by which a portion of the proceeds from sales and costs of reacquiring the Trust’s units, equivalent on a per unit basis to the amount of distributable net investment income on the date of the transaction, is credited or charged to undistributed net investment income. As a result, undistributed net investment income per unit is unaffected by sales or reacquisitions of the Trust’s units.

Federal Income Tax

The Trust has qualified and intends to qualify as a ‘‘regulated investment company’’ under Subchapter M of the Internal Revenue Code of 1986, as amended. By so qualifying and electing, the Trust will not be subject to federal income taxes to the extent it distributes its taxable income, including any net realized capital gains, for each fiscal year. In addition, by distributing during each calendar year substantially all of its net investment income and capital gains, if any, the Trust will not be subject to federal excise tax. Income and capital gain distributions are determined in accordance with income tax regulations which may differ from generally accepted accounting principles. These differences are primarily due to differing treatments for income equalization, in-kind transactions and losses deferred due to wash sales. Net investment income per DIAMOND calculations in the financial highlights for all years presented exclude these differences.

During the fiscal year ended October 31, 2006, the Trust reclassified $413,859,607 of non-taxable security gains realized in the in-kind redemption of Creation Units (Note 4) as an increase to paid in surplus in the Statements of Assets and Liabilities.

October 31, 2006

At October 31, 2006, the Trust had the following capital loss carryforwards which may be used to offset any net realized gains, expiring October 31:


2008 $ 5,933,194  
2010   2,065,467  
2011   68,716,435  
2012   221,460,585  
2014   52,316  

The tax character of distributions paid during the year ended October 31, 2006, 2005, and 2004 were as follows:


Distributions paid from: 2006 2005 2004
Ordinary Income $ 141,435,357   $ 168,178,022   $ 130,617,261  

As of October 31, 2006, the components of distributable earnings (excluding unrealized appreciation (depreciation)) on a federal income tax basis were undistributed ordinary income of $11,417,177 and undistributed long term capital gain of $0.

On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB Interpretation No. 48 ‘‘Accounting for Uncertainty in Income Taxes’’ (FIN 48). FIN 48 provides guidance for how uncertain tax positions should be recognized, measured, presented and disclosed in the financial statements. FIN 48 requires the evaluation of tax positions taken or expected to be taken in the course of preparing a fund’s tax returns to determine whether the tax positions are ‘‘more-likely-than-not’’ of being sustained by the applicable tax authority. Tax positions not deemed to meet the more-likely-than-not threshold would be recorded as a tax benefit or expense in the current year. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. At this time, management is evaluating the implications, if any, of FIN 48 and its impact on the Trust’s financial statements has not yet been determined.

Note 3—Transactions with the Trustee and Sponsor

In accordance with the Trust Agreement, State Street Bank and Trust Company (the ‘‘Trustee’’) maintains the Trust’s accounting records, acts as custodian and transfer agent to the Trust, and provides administrative services, including filing of all required regulatory reports. The Trustee is also responsible for determining the composition of the portfolio of securities which must be delivered and/or received in exchange for the issuance and/or redemption of Creation Units of the Trust, and for adjusting the composition of the Trust’s portfolio from time to time to conform to changes in the composition and/or

weighting structure of the DJIA. For these services, the Trustee received a fee at the following annual rates for the fiscal year ended October 31, 2006:


Net asset value of the Trust Fee as a percentage of net asset value of the Trust
$0 — $499,999,999 10/100 of 1% per annum plus or minus the
Adjustment Amount
$500,000,000 — $2,499,999,999 8/100 of 1% per annum plus or minus the
Adjustment Amount
$2,500,000,000 — and above 6/100 of 1% per annum plus or minus the
Adjustment Amount

The Adjustment Amount is the sum of (a) the excess or deficiency of transaction fees received by the Trustee, less the expenses incurred in processing orders for creation and redemption of DIAMONDS and (b) the excess amounts earned by the Trustee with respect to the cash held by the Trustee for the benefit of the Trust. During the fiscal year ended October 31, 2006, the Adjustment Amount decreased the Trustee’s fee by $359,776. The Adjustment Amount included a deficiency of net transaction fees from processing orders of $59,027 and a Trustee earning credit of $418,803.

Effective November 22, 2006, the Trustee has changed the method of computing the Adjustment Amount to the Trustee Fee such that all income earned with respect to the cash held for the benefit of the Trust is credited against the Trustee’s Fee. In addition, during the period from December 1, 2006 through December 31, 2006, the Trustee will apply an incremental cash balance credits of approximately $375,000 (or less than $0.0003 per share per day, assuming 53 million outstanding shares) against its base fee. Such incremental credit will be calculated and applied on a daily basis for such period.

PDR Services LLC (the ‘‘Sponsor’’, a wholly-owned subsidiary of the American Stock Exchange LLC) agreed to reimburse the Trust for, or assume, the ordinary operating expenses of the Trust which exceeded 18.00/100 of 1% per annum of the daily net asset value of the Trust. The amounts of such reimbursements by the Sponsor for the fiscal years ended October 31, 2004, October 31, 2005 and October 31, 2006 were $0.

Dow Jones & Company, Inc. (‘‘Dow Jones’’), the American Stock Exchange LLC (the ‘‘AMEX’’), and PDR Services (the ‘‘Sponsor’’) and State Street Global Markets, LLC (‘‘SSGM’’) have entered into a License Agreement pursuant to which certain Dow Jones marks may be used in connection with the Trust subject to the payment of license fees. SSGM is a subsidiary of the Trustee.

Indemnifications

Under the Trust’s organizational documents, its officers and trustees are indemnified against certain liability arising out of the performance of their duties to the Trust. Additionally, in the normal course of business, the Trust enters 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 occurred. However, based on experience the Trust expects the risk of loss to be remote.

Such transactions are only permitted on an in-kind basis, with a separate cash payment which is equivalent to the undistributed net investment income per DIAMOND (income equalization) and a balancing cash component to equate the transaction to the net asset value per unit of the Trust on the transaction date. A transaction fee of $1,000 is charged in connection with each creation or redemption of Creation Units through the DIAMONDS Clearing Process per Participating party per day, regardless of the number of Creation Units created or redeemed. Transaction fees are received by the Trustee and used to offset the expense of processing orders.

Note 5—Investment Transactions

For the fiscal year ended October 31, 2006, the Trust had net in-kind contributions, net in-kind redemptions, purchases and sales of investment securities of $13,287,283,074, $11,504,484,973, $678,200 and $720,258, respectively. At October 31, 2006, the cost of investments for federal income tax purposes was $7,141,078,239 accordingly, gross unrealized appreciation was $125,280,804, and gross unrealized depreciation was $713,251,734, resulting in net unrealized depreciation of $587,970,930.

Tax Information

For Federal income tax purposes, the percentage of Trust ordinary distributions which qualify for the corporate dividends received deduction for the fiscal year ended October 31, 2006 is 100%.

For the fiscal year ended October 31, 2006, certain dividends paid by the Trust may be designated as qualified dividend income and subject to a maximum tax rate of 15%, as provided for by the Jobs and Growth Tax Relief Reconciliation Act of 2003. Complete information will be reported in conjunction with your 2006 Form 1099-DIV.

THE TRUST

The Trust, an exchange traded fund or ‘‘ETF’’, is a registered investment company which both (a) continuously issues and redeems ‘‘in-kind’’ its shares, known as DIAMONDS, only in large lot sizes called Creation Units at their once-daily NAV and (b) lists DIAMONDS individually for trading on the Exchange at prices established throughout the trading day, like any other listed equity security trading in the secondary market on the Exchange.

Creation of Creation Units

Portfolio Deposits may be made through the DIAMONDS Clearing Process or outside the DIAMONDS Clearing Process only by a person who executed a Participant Agreement with the Distributor and the Trustee. The Distributor shall reject any order that is not submitted in proper form. A creation order is deemed received by the Distributor on the date on which it is placed (‘‘Transmittal Date’’) if (a) such order is received by the Distributor not later than the Closing Time (as defined below) on such Transmittal Date and (b) all other procedures set forth in the Participant Agreement are properly followed. The Transaction Fee is charged at the time of creation of a Creation Unit, and an additional amount not to exceed three (3) times the Transaction Fee applicable for one Creation Unit is charged for creations outside the DIAMONDS Clearing Process, in part due to the increased expense associated with settlement.

The Trustee, at the direction of the Sponsor, may increase*, reduce or waive the Transaction Fee (and/or the additional amounts charged in connection with creations and/or redemptions outside the DIAMONDS Clearing Process) for certain lot-size creations and/or redemptions of Creation Units. The Sponsor has the right to vary the lot-size of Creation Units subject to such an increase, reduction or waiver. The existence of any such variation shall be disclosed in the then current DIAMONDS Prospectus.

The DJIA is a price-weighted stock index; that is, the component stocks of the DJIA are represented in exactly equal share amounts and therefore are accorded relative importance in the DJIA based on their prices. The shares of common stock of the stock portion of a Portfolio Deposit on any date of deposit will reflect the composition of the component stocks of the DJIA on such day. The portfolio of Index Securities that is the basis for a Portfolio Deposit varies as changes are made in the composition of the Index Securities.

* Such increase is subject to the 10 Basis Point Limit.

28




The Trustee makes available to NSCC* before the commencement of trading on each Business Day a list of the names and required number of shares of each of the Index Securities in the current Portfolio Deposit as well as the amount of the Dividend Equivalent Payment for the previous Business Day. Under certain extraordinary circumstances which may make it impossible for the Trustee to provide such information to NSCC on a given Business Day, NSCC shall use the information regarding the identity of the Index Securities of the Portfolio Deposit on the previous Business Day. The identity of each Index Security required for a Portfolio Deposit, as in effect on October 31, 2006, is set forth in the above Schedule of Investments. The Sponsor makes available (a) on each Business Day, the Dividend Equivalent Payment effective through and including the previous Business Day, per outstanding DIAMONDS unit, and (b) every 15 seconds throughout the day at the Exchange a number representing, on a per DIAMONDS unit basis, the sum of the Dividend Equivalent Payment effective through and including the previous Business Day, plus the current value of the securities portion of a Portfolio Deposit as in effect on such day (which value may occasionally include a cash in lieu amount to compensate for the omission of a particular Index Security from such Portfolio Deposit). Such information is calculated based upon the best information available to the Sponsor and may be calculated by other persons designated to do so by the Sponsor. The inability of the Sponsor to provide such information will not in itself result in a halt in the trading of DIAMONDS on the Exchange. Investors interested in creating DIAMONDS or purchasing DIAMONDS in the secondary market should not rely solely on such information in making investment decisions but should also consider other market information and relevant economic and other factors (including, without limitation, information regarding the DJIA, the Index Securities and financial instruments based on the DJIA).

Upon receipt of one or more Portfolio Deposits, following placement with the Distributor of an order to create DIAMONDS, the Trustee (a) delivers one or more Creation Units to DTC, (b) removes the DIAMONDS unit position from its account at DTC and allocates it to the account of the DTC Participant acting on behalf of the investor creating Creation Unit(s), (c) increases the aggregate value of the Portfolio, and (d) decreases the fractional undivided interest in the Trust represented by each DIAMONDS unit.

Under certain circumstances, (a) a portion of the stock portion of a Portfolio Deposit may consist of contracts to purchase certain Index Securities or (b) a portion of the Cash Component may consist of cash in an amount

* As of December 31, 2006, the Depository Trust and Clearing Corporation (‘‘DTCC’’) owned 100% of the issued and outstanding shares of common stock of NSCC. Also, as of such date, the Exchange no longer owned any of the issued and outstanding shares of common stock of DTCC (‘‘DTCC Shares’’), and the Trustee owned 5.19% of DTCC Shares.

29




required to enable the Trustee to purchase such Index Securities. If there is a failure to deliver Index Securities that are the subject of such contracts to purchase, the Trustee will acquire such Index Securities in a timely manner. To the extent the price of any such Index Security increases or decreases between the time of creation and the time of its purchase and delivery, DIAMONDS will represent fewer or more shares of such Index Security. Therefore, price fluctuations during the period from the time the cash is received by the Trustee to the time the requisite Index Securities are purchased and delivered will affect the value of all DIAMONDS.

Procedures for Creation of Creation Units

All creation orders must be placed in Creation Units and must be received by the Distributor by no later than the closing time of the regular trading session on the NYSE (‘‘Closing Time’’) (ordinarily 4:00 p.m. New York time) in each case on the date such order is placed in order for creation to be effected based on the NAV of the Trust as determined on such date. Orders must be transmitted by telephone or other transmission method acceptable to the Distributor and the Trustee, pursuant to procedures set forth in the Participant Agreement and described in this prospectus. Severe economic or market disruptions or changes, or telephone or other communication failure, may impede the ability to reach the Distributor, the Trustee, a Participating Party or a DTC Participant.

DIAMONDS may be created in advance of receipt by the Trustee of all or a portion of the Portfolio Deposit. In these circumstances, the initial deposit has a value greater than the NAV of the DIAMONDS on the date the order is placed in proper form, because in addition to available Index Securities, cash collateral must be deposited with the Trustee in an amount equal to the sum of (a) the Cash Component, plus (b) 115% of the market value of the undelivered Index Securities (‘‘Additional Cash Deposit’’). The Trustee holds such Additional Cash Deposit as collateral in an account separate and apart from the Trust. The order is deemed received on the Business Day on which the order is placed if the order is placed in proper form before the Closing Time, on such date and federal funds in the appropriate amount are deposited with the Trustee by 11:00 a.m., New York time, the next Business Day.

If the order is not placed in proper form by the Closing Time or federal funds in the appropriate amount are not received by 11:00 a.m. the next Business Day, the order may be deemed to be rejected and the investor shall be liable to the Trust for any losses, resulting therefrom. An additional amount of cash must be deposited with the Trustee, pending delivery of the missing Index Securities to the extent necessary to maintain the Additional Cash Deposit with the Trustee in an amount at least equal to 115% of the daily mark-to-market value of the missing Index Securities. If missing Index Securities are not received by 1:00 p.m., New York time, on the third Business Day following the day on which the purchase order is deemed received and if

30




a mark-to-market payment is not made within one Business Day following notification by the Distributor that such a payment is required, the Trustee may use the Additional Cash Deposit to purchase the missing Index Securities. The Trustee will return any unused portion of the Additional Cash Deposit once all of the missing Index Securities have been properly received or purchased by the Trustee and deposited into the Trust. In addition, a Transaction Fee of $4,000 is charged in all cases. The delivery of Creation Units so created will occur no later than the third (3rd) Business Day following the day on which the purchase order is deemed received. The Participant Agreement for any Participating Party intending to follow these procedures contains terms and conditions permitting the Trustee to buy the missing portion(s) of the Portfolio Deposit at any time and will subject the Participating Party to liability for any shortfall between the cost to the Trust of purchasing such stocks and the value of such collateral. The Participating Party is liable to the Trust for the costs incurred by the Trust in connection with any such purchases. The Trust will have no liability for any such shortfall.

All questions as to the number of shares of each Index Security, the amount of the Cash Component and the validity, form, eligibility (including time of receipt) and acceptance for deposit of any Index Securities to be delivered are resolved by the Trustee. The Trustee may reject a creation order if (a) the depositor or group of depositors, upon obtaining the DIAMONDS ordered, would own 80% or more of the current outstanding DIAMONDS, (b) the Portfolio Deposit is not in proper form; (c) acceptance of the Portfolio Deposit would have certain adverse tax consequences; (d) the acceptance of the Portfolio Deposit would, in the opinion of counsel, be unlawful; (e) the acceptance of the Portfolio Deposit would otherwise have an adverse effect on the Trust or the rights of Beneficial Owners; or (f) circumstances outside the control of the Trustee make it for all practical purposes impossible to process creations of DIAMONDS. The Trustee and the Sponsor are under no duty to give notification of any defects or irregularities in the delivery of Portfolio Deposits or any component thereof and neither of them shall incur any liability for the failure to give any such notification.

Placement of Creation Orders Using DIAMONDS Clearing Process

Creation Units created through the DIAMONDS Clearing Process must be delivered through a Participating Party that has executed a Participant Agreement. The Participant Agreement authorizes the Trustee to transmit to the Participating Party such trade instructions as are necessary to effect the creation order. Pursuant to the trade instructions from the Trustee to NSCC, the Participating Party agrees to transfer the requisite Index Securities (or contracts to purchase such Index Securities that are expected to be delivered through the DIAMONDS Clearing Process in a ‘‘regular way’’ manner by the third NSCC Business Day) and the Cash Component to the Trustee, together with such additional information as may be required by the Trustee.

31




Placement of Creation Orders Outside DIAMONDS Clearing Process

Creation Units created outside the DIAMONDS Clearing Process must be delivered through a DTC Participant that has executed a Participant Agreement and has stated in its order that it is not using the DIAMONDS Clearing Process and that creation will instead be effected through a transfer of stocks and cash. The requisite number of Index Securities must be delivered through DTC to the account of the Trustee by no later than 11:00 a.m. of the next Business Day immediately following the Transmittal Date. The Trustee, through the Federal Reserve Bank wire transfer system, must receive the Cash Component no later than 2:00 p.m. on the next Business Day immediately following the Transmittal Date. If the Trustee does not receive both the requisite Index Securities and the Cash Component in a timely fashion, the order will be cancelled. Upon written notice to the Distributor, the cancelled order may be resubmitted the following Business Day using a Portfolio Deposit as newly constituted to reflect the current NAV of the Trust. The delivery of DIAMONDS so created will occur no later than the third (3rd) Business Day following the day on which the creation order is deemed received by the Distributor.

Securities Depository; Book-Entry-Only System

DTC acts as securities depository for DIAMONDS. DIAMONDS are represented by one or more global securities, registered in the name of Cede & Co., as nominee for DTC and deposited with, or on behalf of, DTC.

DTC is a limited-purpose trust company organized under the laws of the State of New York, a member of the Federal Reserve System, a ‘‘clearing corporation’’ within the meaning of the New York Uniform Commercial Code, and a ‘‘clearing agency’’ registered pursuant to the provisions of Section 17A of the Securities Exchange Act of 1934. DTC * holds securities of its participants (‘‘DTC Participants’’) and to facilitate the clearance and settlement of securities transactions among the DTC Participants through electronic book-entry changes in their accounts, thereby eliminating the need for physical movement of securities certificates. DTC Participants include securities brokers and dealers, banks, trust companies, clearing corporations, and certain other organizations. Access to the DTC system also is available to others, such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a DTC Participant, either directly or indirectly (‘‘Indirect Participants’’).

Upon the settlement date of any creation, transfer or redemption of DIAMONDS, DTC credits or debits, on its book-entry registration and transfer system, the amount of DIAMONDS so created, transferred or

* As of December 31, 2006, DTCC owned 100% of the issued and outstanding shares of the common stock of DTC.

32




redeemed to the accounts of the appropriate DTC Participants. The accounts to be credited and charged are designated by the Trustee to NSCC, in the case of a creation or redemption through the DIAMONDS Clearing Process, or by the Trustee and the DTC Participant, in the case of a creation or redemption outside of the DIAMONDS Clearing Process. Beneficial ownership of DIAMONDS is limited to DTC Participants, Indirect Participants and persons holding interests through DTC Participants and Indirect Participants. Ownership of beneficial interests in DIAMONDS (owners of such beneficial interests are referred to herein as ‘‘Beneficial Owners’’) is shown on, and the transfer of ownership is effected only through, records maintained by DTC (with respect to DTC Participants) and on the records of DTC Participants (with respect to Indirect Participants and Beneficial Owners that are not DTC Participants). Beneficial Owners are expected to receive from or through the DTC Participant a written confirmation relating to their purchase of DIAMONDS. The laws of some jurisdictions may require that certain purchasers of securities take physical delivery of such securities in definitive form. Such laws may impair the ability of certain investors to acquire beneficial interests in DIAMONDS.

As long as Cede & Co., as nominee of DTC, is the registered owner of DIAMONDS, references to the registered or record owner of DIAMONDS shall mean Cede & Co. and shall not mean the Beneficial Owners of DIAMONDS. Beneficial Owners of DIAMONDS are not entitled to have DIAMONDS registered in their names, will not receive or be entitled to receive physical delivery of certificates in definitive form and will not be considered the record or registered holders thereof under the Trust Agreement. Accordingly, each Beneficial Owner must rely on the procedures of DTC, the DTC Participant and any Indirect Participant through which such Beneficial Owner holds its interests, to exercise any rights under the Trust Agreement.

The Trustee recognizes DTC or its nominee as the owner of all DIAMONDS for all purposes except as expressly set forth in the Trust Agreement. Pursuant to the agreement between the Trustee and DTC (‘‘Depository Agreement’’), DTC is required to make available to the Trustee upon request and for a fee to be charged to the Trust a listing of the DIAMONDS holdings of each DTC Participant. The Trustee inquires of each such DTC Participant as to the number of Beneficial Owners holding DIAMONDS, directly or indirectly, through the DTC Participant. The Trustee provides each such DTC Participant with copies of such notice, statement or other communication, in the form, number and at the place as the DTC Participant may reasonably request, in order that the notice, statement or communication may be transmitted by the DTC Participant, directly or indirectly, to the Beneficial Owners. In addition, the Trust pays to each such DTC Participant a fair and reasonable amount as reimbursement for the expense attendant to such transmittal, all subject to applicable statutory and regulatory requirements.

33




Distributions are made to DTC or its nominee, Cede & Co. DTC or Cede & Co., upon receipt of any payment of distributions in respect of DIAMONDS, is required immediately to credit DTC Participants’ accounts with payments in amounts proportionate to their respective beneficial interests in DIAMONDS, as shown on the records of DTC or its nominee. Payments by DTC Participants to Indirect Participants and Beneficial Owners of DIAMONDS held through such DTC Participants will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers in bearer form or registered in a ‘‘street name,’’ and will be the responsibility of such DTC Participants. Neither the Trustee nor the Sponsor has or will have any responsibility or liability for any aspects of the records relating to or notices to Beneficial Owners, or payments made on account of beneficial ownership interests in DIAMONDS, or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests or for any other aspect of the relationship between DTC and the DTC Participants or the relationship between such DTC Participants and the Indirect Participants and Beneficial Owners owning through such DTC Participants.

DTC may discontinue providing its service with respect to DIAMONDS at any time by giving notice to the Trustee and the Sponsor and discharging its responsibilities with respect thereto under applicable law. Under such circumstances, the Trustee and the Sponsor shall take action either to find a replacement for DTC to perform its functions at a comparable cost or, if such a replacement is unavailable, to terminate the Trust.

REDEMPTION OF DIAMONDS

DIAMONDS are redeemable only in Creation Units. Creation Units are redeemable in kind only and are not redeemable for cash except as described under ‘‘Summary—Highlights—Termination of the Trust.’’

Procedures for Redemption of Creation Units

Redemption orders must be placed with a Participating Party (for redemptions through the DIAMONDS Clearing Process) or DTC Participant (for redemptions outside the DIAMONDS Clearing Process), as applicable, in the form required by such Participating Party or DTC Participant. A particular broker may not have executed a Participant Agreement, and redemption orders may have to be placed by the broker through a Participating Party or a DTC Participant who has executed a Participant Agreement. At any given time, there may be only a limited number of broker-dealers that have executed a Participant Agreement. Redeemers should afford sufficient time to permit (a) proper submission of the order by a Participating Party or DTC Participant to the Trustee and (b) the receipt of the DIAMONDS to be redeemed and any Excess Cash Amounts by the Trustee in a timely manner. Orders for

34




redemption effected outside the DIAMONDS Clearing Process are likely to require transmittal by the DTC Participant earlier on the Transmittal Date than orders effected using the DIAMONDS Clearing Process. These deadlines vary by institution. Persons redeeming outside the DIAMONDS Clearing Process are required to transfer DIAMONDS through DTC and the Excess Cash amounts, if any, through the Federal Reserve Bank wire transfer system in a timely manner.

Requests for redemption may be made on any Business Day to the Trustee and not to the Distributor. In the case of redemptions made through the DIAMONDS Clearing Process, the Transaction Fee is deducted from the amount delivered to the redeemer. In the case of redemptions outside the DIAMONDS Clearing Process, the Transaction Fee plus an additional amount not to exceed three (3) times the Transaction Fee applicable for one Creation Unit per Creation Unit redeemed, and such amount is deducted from the amount delivered to the redeemer.

The Trustee transfers to the redeeming Beneficial Owner via DTC and the relevant DTC Participant(s) a portfolio of stocks for each Creation Unit delivered, generally identical in weighting and composition to the stock portion of a Portfolio Deposit as in effect (a) on the date a request for redemption is deemed received by the Trustee or (b) in the case of the termination of the Trust, on the date that notice of the termination of the Trust is given. The Trustee also transfers via the relevant DTC Participant(s) to the redeeming Beneficial Owner a ‘‘Cash Redemption Payment,’’ which on any given Business Day is an amount identical to the amount of the Cash Component and is equal to a proportional amount of the following: dividends on the Portfolio Securities for the period through the date of redemption, net of expenses and liabilities for such period including, without limitation, (i) taxes or other governmental charges against the Trust not previously deducted if any, and (ii) accrued fees of the Trustee and other expenses of the Trust, as if the Portfolio Securities had been held for the entire accumulation period for such distribution, plus or minus the Balancing Amount. The redeeming Beneficial Owner must deliver to the Trustee any amount by which the amount payable to the Trust by such Beneficial Owner exceeds the amount of the Cash Redemption Payment (‘‘Excess Cash Amounts’’). For redemptions through the DIAMONDS Clearing Process, the Trustee effects a transfer of the Cash Redemption Payment and stocks to the redeeming Beneficial Owner by the third (3rd) NSCC Business Day following the date on which request for redemption is deemed received. For redemptions outside the DIAMONDS Clearing Process, the Trustee transfers the Cash Redemption Payment and the stocks to the redeeming Beneficial Owner by the third (3rd) Business Day following the date on which the request for redemption is deemed received. The Trustee will cancel all DIAMONDS delivered upon redemption.

If the Trustee determines that an Index Security is likely to be unavailable or available in insufficient quantity for delivery by the Trust upon redemption,

35




the Trustee may elect to deliver the cash equivalent value of any such Index Securities, based on its market value as of the Evaluation Time on the date such redemption is deemed received by the Trustee as a part of the Cash Redemption Payment in lieu thereof.

If a redeemer is restricted by regulation or otherwise from investing or engaging in a transaction in one or more Index Securities, the Trustee may elect to deliver the cash equivalent value based on the market value of any such Index Securities as of the Evaluation Time on the date of the redemption as a part of the Cash Redemption Payment in lieu thereof. In such case, the investor will pay the Trustee the standard Transaction Fee, and may pay an additional amount equal to the actual amounts incurred in connection with such transaction(s) but in any case not to exceed three (3) times the Transaction Fee applicable for one Creation Unit.

The Trustee upon the request of a redeeming investor, may elect to redeem Creation Units in whole or in part by providing such redeemer, with a portfolio of stocks differing in exact composition from Index Securities but not differing in NAV from the then-current Portfolio Deposit. Such a redemption is likely to be made only if it were determined that it would be appropriate in order to maintain the Trust’s correspondence to the composition and weighting of the DJIA Index.

The Trustee may sell Portfolio Securities to obtain sufficient cash proceeds to deliver to the redeeming Beneficial Owner. To the extent cash proceeds are received by the Trustee in excess of the required amount, such cash proceeds shall be held by the Trustee and applied in accordance with the guidelines applicable to residual cash set forth under ‘‘The Portfolio—Portfolio Securities Conform to the DJIA’’.

All redemption orders must be transmitted to the Trustee by telephone or other transmission method acceptable to the Trustee so as to be received by the Trustee not later than the Closing Time on the Transmittal Date, pursuant to procedures set forth in the Participant Agreement. Severe economic or market disruption or changes, or telephone or other communication failure, may impede the ability to reach the Trustee, a Participating Party, or a DTC Participant.

The calculation of the value of the stocks and the Cash Redemption Payment to be delivered to the redeeming Beneficial Owner is made by the Trustee according to the procedures set forth under ‘‘Valuation’’ and is computed as of the Evaluation Time on the Business Day on which a redemption order is deemed received by the Trustee. Therefore, if a redemption order in proper form is submitted to the Trustee by a DTC Participant not later than the Closing Time on the Transmittal Date, and the requisite DIAMONDS are delivered to the Trustee prior to DTC Cut-Off Time on such Transmittal Date, then the value of the stocks and the Cash Redemption Payment to be delivered to the Beneficial Owner is determined by the Trustee

36




as of the Evaluation Time on such Transmittal Date. If, however, a redemption order is submitted not later than the Closing Time on a Transmittal Date but either (a) the requisite DIAMONDS are not delivered by DTC Cut-Off Time on the next Business Day immediately following such Transmittal Date or (b) the redemption order is not submitted in proper form, then the redemption order is not deemed received as of such Transmittal Date. In such case, the value of the stocks and the Cash Redemption Payment to be delivered to the Beneficial Owner is computed as of the Evaluation Time on the Business Day that such order is deemed received by the Trustee, i.e., the Business Day on which the DIAMONDS are delivered through DTC to the Trustee by DTC Cut-Off Time on such Business Day pursuant to a properly submitted redemption order.

The Trustee may suspend the right of redemption, or postpone the date of payment of the NAV for more than five (5) Business Days following the date on which the request for redemption is deemed received by the Trustee (a) for any period during which the New York Stock Exchange is closed, (b) for any period during which an emergency exists as a result of which disposal or evaluation of the Portfolio Securities is not reasonably practicable, (c) or for such other period as the SEC may by order permit for the protection of Beneficial Owners. Neither the Sponsor nor the Trustee is liable to any person or in any way for any loss or damages that may result from any such suspension or postponement.

Placement of Redemption Orders Using DIAMONDS Clearing Process

A redemption order made through the DIAMONDS Clearing Process is deemed received on the Transmittal Date if (a) such order is received by the Trustee not later than the Closing Time on such Transmittal Date and (b) all other procedures set forth in the Participant Agreement are properly followed. The order is effected based on the NAV of the Trust as determined as of the Evaluation Time on the Transmittal Date. A redemption order made through the DIAMONDS Clearing Process and received by the Trustee after the Closing Time will be deemed received on the next Business Day immediately following the Transmittal Date. The Participant Agreement authorizes the Trustee to transmit to NSCC on behalf of the Participating Party such trade instructions as are necessary to effect the Participating Party’s redemption order. Pursuant to such trade instructions from the Trustee to NSCC, the Trustee transfers the requisite stocks (or contracts to purchase such stocks which are expected to be delivered in a ‘‘regular way’’ manner) by the third (3rd) NSCC Business Day following the date on which the request for redemption is deemed received, and the Cash Redemption Payment.

Placement of Redemption Orders Outside DIAMONDS Clearing Process

A DTC Participant who wishes to place an order for redemption of DIAMONDS to be effected outside the DIAMONDS Clearing Process need

37




not be a Participating Party, but its order must state that the DTC Participant is not using the DIAMONDS Clearing Process and that redemption will instead be effected through transfer of DIAMONDS directly through DTC. An order is deemed received by the Trustee on the Transmittal Date if (a) such order is received by the Trustee not later than the Closing Time on such Transmittal Date, (b) such order is preceded or accompanied by the requisite number of DIAMONDS specified in such order, which delivery must be made through DTC to the Trustee no later than 11:00 a.m. on the next Business Day immediately following such Transmittal Date (‘‘DTC Cut-Off Time’’) and (c) all other procedures set forth in the Participant Agreement are properly followed. Any Excess Cash Amounts owed by the Beneficial Owner must be delivered no later than 2:00 p.m. on the next Business Day immediately following the Transmittal Date.

The Trustee initiates procedures to transfer the requisite stocks (or contracts to purchase such stocks that are expected to be delivered within three Business Days and the Cash Redemption Payment to the redeeming Beneficial Owner by the third Business Day following the Transmittal Date.

THE PORTFOLIO

Because the objective of the Trust is to provide investment results that, before expenses, generally correspond to the price and yield performance of the DJIA, the Portfolio at any time will consist of as many of Index Securities as is practicable. It is anticipated that cash or cash items (other than dividends held for distribution) normally would not be a substantial part of the Trust’s net assets. Although the Trust may at any time fail to own certain of Index Securities, the Trust will be substantially invested in Index Securities and the Sponsor believes that such investment should result in a close correspondence between the investment performance of the DJIA and that derived from ownership of DIAMONDS.

Portfolio Securities Conform to the DJIA

The DJIA is a price-weighted index of 30 component common stocks, the components of which are determined by the editors of The Wall Street Journal, without any consultation with the companies, the respective stock exchange or any official agency.

The Trust is not managed and therefore the adverse financial condition of an issuer does not require the sale of stocks from the Portfolio. The Trustee on a non-discretionary basis adjusts the composition of the Portfolio to conform to changes in the composition and/or weighting structure of Index Securities. To the extent that the method of determining the DJIA is changed by Dow Jones in a manner that would affect the adjustments provided for herein, the Trustee and the Sponsor have the right to amend the Trust Agreement, without the consent of DTC or Beneficial Owners, to conform the adjustments to such changes and to maintain the objective of tracking the DJIA.

38




The Trustee aggregates certain of these adjustments and makes conforming changes to the Portfolio at least monthly. The Trustee directs its stock transactions only to brokers or dealers, which may include affiliates of the Trustee, from whom it expects to obtain the most favorable prices or execution of orders. Adjustments are made more frequently in the case of significant changes to the DJIA. Specifically, the Trustee is required to adjust the composition of the Portfolio whenever there is a change in the identity of any Index Security (i.e., a substitution of one security for another) within three (3) Business Days before or after the day on which the change is scheduled to take effect. While other DJIA changes may lead to adjustments in the Portfolio, the most common changes are likely to occur as a result of changes in the Index Securities included in the DJIA and as a result of stock splits. The Trust Agreement sets forth the method of adjustments which may occur thereunder as a result of corporate actions to the DJIA, such as stock splits or changes in the identity of the component stocks.

For example, in the event of an Index Security change (in which the common stock of one issuer held in the DJIA is replaced by the common stock of another), the Trustee may sell all shares of the Portfolio Security corresponding to the old Index Security and use the proceeds of such sale to purchase the replacement Portfolio Security corresponding to the new Index Security. If the share price of the removed Portfolio Security was higher than the price of its replacement, the Trustee will calculate how to allocate the proceeds of the sale of the removed Portfolio Security between the purchase of its replacement and purchases of additional shares of other Portfolio Securities so that the number of shares of each Portfolio Security after the transactions would be as nearly equal as practicable. If the share price of the removed Portfolio Security was lower than the price of its replacement, the Trustee will calculate the number of shares of each of the other Portfolio Securities that must be sold in order to purchase enough shares of the replacement Portfolio Security so that the number of shares of each Portfolio Security after the transactions would be as nearly equal as practicable.

In the event of a stock split, the price weighting of the stock which is split will drop. The Trustee may make the corresponding adjustment by selling the additional shares of the Portfolio Security received from the stock split. The Trustee may then use the proceeds of the sale to buy an equal number of shares of each Portfolio Security-including the Portfolio Security which had just experienced a stock split. In practice, of course, not all the shares received in the split would be sold: enough of those shares would be retained to make an increase in the number of split shares equal to the increase in the number of shares in each of the other Portfolio Securities purchased with the proceeds of the sale of the remaining shares resulting from such split.

As a result of the purchase and sale of stock in accordance with these requirements, or the creation of Creation Units, the Trust may hold some amount of residual cash (other than cash held temporarily due to timing

39




differences between the sale and purchase of stock or cash delivered in lieu of Index Securities or undistributed income or undistributed capital gains). This amount may not exceed for more than two (2) consecutive Business Days 5/10th of 1 percent of the value of the Portfolio. If the Trustee has made all required adjustments and is left with cash in excess of 5/10th of 1 percent of the value of the Portfolio, the Trustee will use such cash to purchase additional Index Securities.

All portfolio adjustments are made as described herein unless such adjustments would cause the Trust to lose its status as a ‘‘regulated investment company’’ under Subchapter M of the Code. Additionally, the Trustee is required to adjust the composition of the Portfolio at any time to insure the continued qualification of the Trust as a regulated investment company.

The Trustee relies on Dow Jones for information as to the composition and weightings of Index Securities. If the Trustee becomes incapable of obtaining or processing such information or NSCC is unable to receive such information from the Trustee on any Business Day, the Trustee shall use the composition and weightings of Index Securities for the most recently effective Portfolio Deposit for the purposes of all adjustments and determinations (including, without limitation, determination of the stock portion of the Portfolio Deposit) until the earlier of (a) such time as current information with respect to Index Securities is available or (b) three (3) consecutive Business Days have elapsed. If such current information is not available and three (3) consecutive Business Days have elapsed, the composition and weightings of Portfolio Securities (as opposed to Index Securities) shall be used for the purposes of all adjustments and determinations (including, without limitation, determination of the stock portion of the Portfolio Deposit) until current information with respect to Index Securities is available.

If the Trust is terminated, the Trustee shall use the composition and weightings of Portfolio Securities as of such notice date for the purpose and determination of all redemptions or other required uses of the basket.

From time to time Dow Jones may adjust the composition of the DJIA because of a merger or acquisition involving one or more Index Securities. In such cases, the Trust, as shareholder of an issuer that is the object of such merger or acquisition activity, may receive various offers from would-be acquirors of the issuer. The Trustee is not permitted to accept any such offers until such time as it has been determined that the stocks of the issuer will be removed from the DJIA. As stocks of an issuer are often removed from the DJIA only after the consummation of a merger or acquisition of such issuer, in selling the securities of such issuer the Trust may receive, to the extent that market prices do not provide a more attractive alternative, whatever consideration is being offered to the shareholders of such issuer that have not tendered their shares prior to such time. Any cash received in such transactions is reinvested in Index Securities in accordance with the criteria set forth above.

40




Any stocks received as a part of the consideration that are not Index Securities are sold as soon as practicable and the cash proceeds of such sale are reinvested in accordance with the criteria set forth above.

Adjustments to the Portfolio Deposit

On each Business Day (each such day an ‘‘Adjustment Day’’), the number of shares and identity of each Index Security in a Portfolio Deposit are adjusted in accordance with the following procedure. At the close of the market the Trustee calculates the NAV of the Trust. The NAV is divided by the number of outstanding DIAMONDS multiplied by 50,000 DIAMONDS in one Creation Unit, resulting in a NAV per Creation Unit (‘‘NAV Amount’’). The Trustee then calculates the number of shares (without rounding) of each of the component stocks of the DJIA in a Portfolio Deposit for the following Business Day (‘‘Request Day’’), so that (a) the market value at the close of the market on the Adjustment Day of the stocks to be included in the Portfolio Deposit on Request Day, together with the Dividend Equivalent Payment effective for requests to create or redeem on the Adjustment Day, equals the NAV Amount and (b) the identity and weighting of each of the stocks in a Portfolio Deposit mirrors proportionately the identity and weightings of the stocks in the DJIA, each as in effect on Request Day. For each stock, the number resulting from such calculation is rounded down to the nearest whole share. The identities and weightings of the stocks so calculated constitute the stock portion of the Portfolio Deposit effective on Request Day and thereafter until the next subsequent Adjustment Day, as well as Portfolio Securities to be delivered by the Trustee in the event of request for redemption on the Request Day and thereafter until the following Adjustment Day.

In addition to the foregoing adjustments, if a corporate action such as a stock split, stock dividend or reverse split occurs with respect to any Index Security that does not result in an adjustment to the DJIA divisor, the Portfolio Deposit shall be adjusted to take into account the corporate action in each case rounded to the nearest whole share.

On the Request Day and on each day that a request for the creation or redemption is deemed received, the Trustee calculates the market value of the stock portion of the Portfolio Deposit as in effect on the Request Day as of the close of the market and adds to that amount the Dividend Equivalent Payment effective for requests to create or redeem on Request Day (such market value and Dividend Equivalent Payment are collectively referred to herein as ‘‘Portfolio Deposit Amount’’). The Trustee then calculates the NAV Amount, based on the close of the market on the Request Day. The difference between the NAV Amount so calculated and the Portfolio Deposit Amount is the ‘‘Balancing Amount’’. The Balancing Amount serves the function of compensating for any differences between the value of the Portfolio Deposit Amount and the NAV Amount at the close of trading on Request Day due to, for example, (a) differences in the market value of the securities in the Portfolio

41




Deposit and the market value of the Securities on Request Day and (b) any variances from the proper composition of the Portfolio Deposit.

The Dividend Equivalent Payment and the Balancing Amount in effect at the close of business on the Request Date are collectively referred to as the Cash Component or the Cash Redemption Payment. If the Balancing Amount is a positive number (i.e., if the NAV Amount exceeds the Portfolio Deposit Amount) then, with respect to creation, the Balancing Amount increases the Cash Component of the then effective Portfolio Deposit transferred to the Trustee by the creator. With respect to redemptions, the Balancing Amount is added to the cash transferred to the redeemer by the Trustee. If the Balancing Amount is a negative number (i.e., if the NAV Amount is less than the Portfolio Deposit Amount) then, with respect to creation, this amount decreases the Cash Component of the then effective Portfolio Deposit to be transferred to the Trustee by the creator or, if such cash portion is less than the Balancing Amount, the difference must be paid by the Trustee to the creator. With respect to redemptions, the Balancing Amount is deducted from the cash transferred to the redeemer or, if such cash is less than the Balancing Amount, the difference must be paid by the redeemer to the Trustee.

If the Trustee has included the cash equivalent value of one or more Index Securities in the Portfolio Deposit because the Trustee has determined that such Index Securities are likely to be unavailable or available in insufficient quantity for delivery, or if a creator or redeemer is restricted from investing or engaging in transactions in one or more of such Index Securities, the Portfolio Deposit so constituted shall determine the Index Securities to be delivered in connection with the creation of DIAMONDS in Creation Unit size aggregations and upon the redemption of DIAMONDS until the time the stock portion of the Portfolio Deposit is subsequently adjusted.

THE DJIA

The DJIA was first published in 1896. Initially comprised of 12 companies, the DJIA has evolved into the most recognizable stock indicator in the world, and the only index composed of companies that have sustained earnings performance over a significant period of time. In its second century, the DJIA is the oldest continuous barometer of the U.S. stock market, and the most widely quoted indicator of U.S. stock market activity.

The 30 stocks now comprising the DJIA are all leaders in their respective industries, and their stocks are widely held by individuals and institutional investors. These stocks represent more than one-quarter of the $14.4 trillion market value of all US common stocks.

Dow Jones is not responsible for and shall not participate in the creation or sale of DIAMONDS or in the determination of the timing of, prices at, or quantities and proportions in which purchases or sales of Index Securities or Securities shall be made. The information in this Prospectus concerning Dow

42




Jones and the DJIA has been obtained from sources that the Sponsor believes to be reliable, but the Sponsor takes no responsibility for the accuracy of such information.

The following table shows the actual performance of the DJIA for the years 1896 through 2006. Stock prices fluctuated widely during this period and were higher at the end than at the beginning. The results shown should not be considered as a representation of the income yield or capital gain or loss that may be generated by the DJIA in the future, nor should the results be considered as a representation of the performance of the Trust.
