(2) Amount shown represents less than $0.005. (3) Total return is calculated assuming a purchase of shares at net asset value per share on the first day and a sale at net asset value per share on the last day of each period reported. Distributions are assumed, for the purposes of this calculation, to be reinvested at the net asset value per share on the respective payment dates of the Fund. Total return for a period of less than one year is not annualized. Broker commission charges are not included in the calculation. (4) Portfolio turnover ratio excludes securities received or delivered from processing creations or redemptions of DIAMONDS (5) Net investment income per unit reflects receipt of a one time dividend from a portfolio holding (Microsoft Corp.). The effect of this dividend amounted to $0.22 per share. See accompanying notes to financial statements. 5 DIAMONDS TRUST, SERIES 1 NOTES TO FINANCIAL STATEMENTS APRIL 30, 2008 (UNAUDITED) -------------------------------------------------------------------------------- NOTE 1 -- ORGANIZATION DIAMONDS Trust, Series 1 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" and collectively as "DIAMONDS". 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. Under the Trust Agreement, the Sponsor and Trustee (each as defined below) are indemnified against certain liabilities arising from 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. 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 affect 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, Statement 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. The Trustee is currently evaluating the impact, if any, the adoption of SFAS 157 will have on the Fund's financial statements. The Trustee does not anticipate SFAS 157 will have a material impact 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. 6 DIAMONDS TRUST, SERIES 1 NOTES TO FINANCIAL STATEMENTS -- (CONTINUED) APRIL 30, 2008 (UNAUDITED) -------------------------------------------------------------------------------- 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 share calculations in the financial highlights for all years presented exclude these differences. During the six months ended April 30, 2008, the Trust reclassified $197,138,304 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. At April 30, 2008, the Trust had the following capital loss carryforwards which may be used to offset any net realized gains, expiring October 31: 2008...................................... $ 5,816,675 2010...................................... 2,065,467 2011...................................... 68,716,435 2012...................................... 221,460,585 2014...................................... 52,316 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 the Fund's tax returns to 7 DIAMONDS TRUST, SERIES 1 NOTES TO FINANCIAL STATEMENTS -- (CONTINUED) APRIL 30, 2008 (UNAUDITED) -------------------------------------------------------------------------------- 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. In adopting FIN 48 with respect to the Trust, management evaluated the implications of FIN 48 and determined that all of the Trust's tax positions meet the "more-likely-than-not" threshold. As a result, the financial statements have not been impacted by the adoption of FIN 48. However, management's conclusions regarding FIN 48 are subject to review and adjustment at a later date based on factors including, but not limited to, further implementation guidance expected from FASB and on-going analysis of tax laws, regulation, and interpretations thereof. 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 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 six months ended April 30, 2008: FEE AS A PERCENTAGE OF NET ASSET VALUE NET ASSET VALUE OF THE TRUST 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 amounts earned by the Trustee with respect to the cash held by the Trustee for the benefit of the Trust. During the six months ended April 30, 2008, the Adjustment Amount reduced the Trustee's fee by $521,872. The Adjustment Amount included an excess of net transaction fees from processing orders of $237,466 and a Trustee earning credit of $284,406. 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. There were no such reimbursements by the Sponsor for the fiscal years ended October 31, 2005, October 31, 2006, October 31, 2007 and six months ended April 30, 2008. Dow Jones, the American Stock Exchange LLC (the "AMEX"), the Sponsor and State Street Global Markets, LLC ("SSGM") have entered into a License Agreement. The License Agreement grants SSGM, an affiliate of the Trustee, a license to use the DJIA as a basis for determining the composition of the Portfolio and to use certain trade names and trademarks of Dow Jones in connection with the Portfolio. The Trustee on behalf of the Trust, the 8 DIAMONDS TRUST, SERIES 1 NOTES TO FINANCIAL STATEMENTS -- (CONTINUED) APRIL 30, 2008 (UNAUDITED) -------------------------------------------------------------------------------- Sponsor and the Exchange have each received a sublicense from SSGM for the use of the DJIA and such trade names and trademarks in connection with their rights and duties with respect to the Trust. The License Agreement may be amended without the consent of any of the Beneficial Owners of DIAMONDS. Currently, the License Agreement is scheduled to terminate on December 31, 2017, but its term may be extended without the consent of any of the Beneficial Owners of DIAMONDS. The Trust pays an annual sub-license fee to Dow Jones of an amount equal to 0.05% on the first $1 billion of the then rolling average asset balance, and 0.04% on any excess rolling average asset balance over and above $1 billion. The minimum annual fee for the Trust is $1 million.

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. Transaction fees at scheduled amounts ranging from $1,000 to $4,000 are 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.
