Cumulative total returns are not annualized. The Fund's total returns shown do not reflect the deduction of income taxes on an individual's investment. Taxes may reduce your actual investment returns on income or gains paid by the Fund or any gains you may realize if you sell your shares. INVESTORS SHOULD CONSIDER THE FUND'S INVESTMENT OBJECTIVES, RISKS, AND OTHER CHARGES AND EXPENSES CAREFULLY BEFORE INVESTING. THE FUND'S PROSPECTUS CONTAINS THIS AND OTHER INFORMATION ABOUT THE FUND, AND MAY BE OBTAINED BY ASKING YOUR FINANCIAL ADVISOR, CALLING US AT 1.800.525.7048 OR VISITING OUR WEBSITE AT WWW.OPPENHEIMERFUNDS.COM. READ THE PROSPECTUS CAREFULLY BEFORE INVESTING. The Fund's investment strategy and focus can change over time. The mention of specific fund holdings does not constitute a recommendation by OppenheimerFunds, Inc. The Fund has entered into a warranty agreement (the "Warranty") with Merrill Lynch Bank USA (the "Warranty Provider") which attempts to make sure that the value of each shareholder's account on the maturity date (December 16, 2011) will be at least equal to a shareholder's original investment (reduced by any adjustments to the warranty amount permitted by the Warranty, and less any redemptions of Fund shares or distributions taken in cash, sales charges, and extraordinary Fund expenses). The Warranty is solely the obligation of the Warranty Provider, not the shareholders. The Warranty is dependent on the financial ability of the Warranty Provider to make payment to the Fund on the Maturity Date. The Warranty Amount will be reduced by any redemptions of Fund shares or distributions taken in cash, sales charges and extraordinary fund expenses. Distributions from the Fund are taxable whether or not shareholders reinvest them in additional shares of the Fund. The Warranty does not apply to shares redeemed during the Warranty Period, and shareholders can lose money on shares unless redeemed on the Maturity Date. Neither the Fund nor OppenheimerFunds, Inc. is obligated to replace the Warranty Provider should it be unable to make payments necessary to support the Warranty Amount. The Warranty increases the 14 | OPPENHEIMER PRINCIPAL PROTECTED MAIN STREET FUND III Fund's expenses that shareholders pay and could lower Fund performance. Shareholders must redeem their shares in the Fund on, and only on, the Maturity Date (expected to be December 16, 2011) to receive the greater of the then-current net asset value of the Fund or their Warranty Amount. Prior to the Maturity Date, the Fund will provide each shareholder a notice to remind them that shares must be redeemed on the Maturity Date to receive the full benefit of the Warranty. After the Maturity Date, shares of the Fund will not be covered under the terms of the Warranty and will be subject to market fluctuations and the shares will then be redeemable at the Fund's then-current net asset value, which may be lower than the Warranty Amount. Shares may be exchanged or redeemed at any time. However, if you redeem or exchange shares prior to the end of the seven-year Warranty Period, you will receive the then-current NAV per share, which may be higher or lower than the Warranty Amount. To receive at least the full Warranty Amount, you must maintain your original investment in the Fund until the end of the seven-year term and reinvest all dividends and distributions. During the Warranty Period, there are substantial opportunity costs. Allocating assets to U.S. Government securities (primarily Treasury STRIPS) reduces the Fund's ability to participate fully in upward equity market movements. Therefore, it represents some loss of opportunity, or opportunity cost, compared to a portfolio that is fully invested in equities. In the event that the Fund's stock allocation declines substantially, generally due to heavy stock market declines, the Fund will permanently shift all investments to fixed income securities and certain of the Fund's expenses will be reduced. In the event of reallocation of 100% of the Fund's assets to U.S. Government securities, the Fund will not be permitted to allocate its assets to equity securities for the remainder of the Warranty Period, which will eliminate the Fund's ability to participate in any upward equity market movement. While these fixed income securities (primarily Treasury STRIPS) that the Fund invests in do not pay income the traditional way, an income calculation is made for tax purposes based on the purchase price and the time until the security reaches par value. Like traditional interest payments, this amount is reported as income for tax purposes. The zero coupon bonds the Fund 15 | OPPENHEIMER PRINCIPAL PROTECTED MAIN STREET FUND III NOTES - -------------------------------------------------------------------------------- invests in do not pay interest income until maturity. However, the Fund is required to accrue and declare a dividend on such income. Thus, you will have taxable income. Distributions from the Fund are taxable whether or not you reinvest them in additional shares of the Fund. The Fund is not obligated to replace the Warranty Provider should it be unable to make the payments necessary to support the Warranty Amount. The Warranty increases the Fund's expenses that you pay and therefore the Fund's expenses will generally be higher than a fund that does not offer a Warranty. All investments have risks to some degree. Stocks and S&P 500 Index Futures fluctuate in price and their volatility at times may be great. If the issuer of an S&P 500 Index Future does not pay the amount due, the Fund can lose money on the investment. All investments have risks to some degree. Stocks fluctuate in price and their volatility at times may be great. While principal and interest payments on U.S. Treasury securities are guaranteed by the U.S. Government, the price of such securities will fluctuate with changes in prevailing interest rates. Zero-coupon U.S. Government securities are subject to greater fluctuations in price from interest rate changes than typical debt securities that pay interest on a regular basis. Investors should be aware that principal protected funds generally carry higher fees and expenses than non-protected funds. The Fund offered its shares to the public from October 7, 2004 to December 10, 2004. From December 16, 2004, and until December 16, 2011, shares of the Fund will only be issued upon reinvestment of dividends and distributions. An explanation of the calculation of performance is in the Fund's Statement of Additional Information. 16 | OPPENHEIMER PRINCIPAL PROTECTED MAIN STREET FUND III FUND EXPENSES - -------------------------------------------------------------------------------- FUND EXPENSES. As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, which may include sales charges (loads) on purchase payments, contingent deferred sales charges on redemptions; and redemption fees (if applicable); and (2) ongoing costs, including management fees; distribution and service fees; and other Fund expenses. These examples are intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The examples are based on an investment of $1,000.00 invested at the beginning of the period and held for the entire 6-month period ended February 29, 2008. ACTUAL EXPENSES. The first section of the table provides information about actual account values and actual expenses. You may use the information in this section for the class of shares you hold, together with the amount you invested, to estimate the expense that you paid over the period. Simply divide your account value by $1,000.00 (for example, an $8,600.00 account value divided by $1,000.00 = 8.60), then multiply the result by the number in the first section under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES. The second section of the table provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio for each class of shares, and an assumed rate of return of 5% per year for each class before expenses, which is not the actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example for the class of shares you hold with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as front-end or contingent deferred sales charges (loads), or a $12.00 fee imposed annually on accounts valued at less than $500.00 (subject to exceptions described in 17 | OPPENHEIMER PRINCIPAL PROTECTED MAIN STREET FUND III FUND EXPENSES Continued - -------------------------------------------------------------------------------- the Statement of Additional Information). Therefore, the "hypothetical" section of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

Those annualized expense ratios, excluding indirect expenses from affiliated funds, based on the 6-month period ended February 29, 2008 are as follows: CLASS EXPENSE RATIOS - --------------------------- Class A 1.22% - --------------------------- Class B 2.06 - --------------------------- Class C 1.97 - --------------------------- Class N 1.38 The expense ratios reflect reduction to custodian expenses and voluntary waivers or reimbursements of expenses by the Fund's Manager that can be terminated at any time, without advance notice. The "Financial Highlights" tables in the Fund's financial statements, included in this report, also show the gross expense ratios, without such waivers or reimbursements and reduction to custodian expenses, if applicable. 18 | OPPENHEIMER PRINCIPAL PROTECTED MAIN STREET FUND III STATEMENT OF INVESTMENTS February 29, 2008/ Continued - -------------------------------------------------------------------------------- SHARES VALUE - ------------------------------------------------------------------------------------------------------------- - ------------------------------------------------------------------------------------------------------------- INVESTMENT COMPANIES--40.5% 1 - ------------------------------------------------------------------------------------------------------------- MONEY MARKET FUND--10.2% Oppenheimer Institutional Money Market Fund, Cl.

SIGNIFICANT ACCOUNTING POLICIES Oppenheimer Principal Protected Main Street Fund III (the "Fund"), a series of Oppenheimer Principal Protected Trust III, is registered under the Investment Company Act of 1940, as amended, as an open-end management investment company. During the Warranty Period, the Fund will seek capital preservation in order to have a net asset value on the Maturity Date at least equal to the Warranty Amount. The Fund seeks high total return as a secondary objective. The Fund's investment adviser is OppenheimerFunds, Inc. (the "Manager"). Shares of the Fund were offered during the Offering Period (October 7, 2004 to December 10, 2004). Shares are not offered during the Warranty Period (December 16, 2004 to December 16, 2011) to the Maturity Date (December 16, 2011) except in connection with reinvestment of dividends and distributions. During the Warranty Period, the Fund will allocate its assets between Oppenheimer Main Street Fund (the "Underlying Fund"), futures contracts on the S&P 500 Index and certain U.S. government securities. The allocation of the Fund's assets between the debt portfolio and the equity portfolio will vary over time based upon the Warranty Formula. The formula is intended to allow the Fund to have a net asset value on the Maturity Date at least equal to the Warranty Amount. During the Warranty Period, the Fund will invest a portion of its assets, and in certain circumstances, the Fund may invest all of its assets, in U.S. government securities having maturities approximately equal to the period remaining in the Warranty Period. The Fund offered Class A, Class B, Class C and Class N shares. Class A shares were sold at their offering price, which is normally net asset value plus a front-end sales charge. Class B and Class C shares were sold without a front-end sales charge but may be subject to a contingent deferred sales charge (CDSC). Class N shares were sold only through retirement plans. All classes of shares have identical rights and voting privileges with respect to the Fund in general and exclusive voting rights on matters that affect that class alone. Earnings, net assets and net asset value per share may differ due to each class having its own expenses, such as transfer and shareholder servicing agent fees and shareholder communications, directly attributable to that class. Class A, B, C and N have separate distribution and/or service plans. Class B shares will automatically convert to Class A shares 90 months after the date of purchase. The following is a summary of significant accounting policies consistently followed by the Fund. - -------------------------------------------------------------------------------- WARRANTY AGREEMENT. The Fund has entered into a Financial Warranty Agreement with Merrill Lynch Bank USA ("the Warranty Provider") to ensure that on the Maturity Date each shareholder's account will be no less than the value of that shareholder's account on the second business day after the end of the Offering Period (the Warranty Amount). This value will include net income, if any, earned by the Fund during the offering period and be reduced by adjustments permitted under the Warranty Agreement, sales charges, applicable share of extraordinary expenses and proportionately reduced for dividends and distributions paid in cash and redemptions of Fund shares. To avoid a reduced Warranty Amount, shareholders must reinvest all dividends and distributions received 30 | OPPENHEIMER PRINCIPAL PROTECTED MAIN STREET FUND III from the Fund to purchase additional shares of the Fund and must not redeem any shares of the Fund during the Warranty Period. If the value of the Fund's assets on the Maturity Date is insufficient to result in the value of each shareholder's account being at least equal to the shareholder's Warranty Amount, the Warranty Provider will pay the Fund an amount equal to the excess of his or her Warranty Amount over his or her account value. The Financial Warranty is solely the obligation of the Warranty Provider. It is possible that the financial position of the Warranty Provider may deteriorate and it would be unable to satisfy its obligations under the Financial Warranty. The Fund's assets and the obligations of the Warranty Provider under the Warranty Agreement are not guaranteed by Merrill Lynch & Co., Inc. (the Warranty Provider's parent company), the United States Government, the Manager, or any other entity or person. The Warranty Agreement requires the Manager, on behalf of the Fund, to comply with certain agreed upon investment parameters in an attempt to limit the Fund's risk. If the Manager fails to comply with the agreed-upon investment parameters or otherwise fails to comply with certain requirements set forth in the Warranty Agreement, the Warranty Provider may terminate its Financial Warranty in certain limited circumstances. The Warranty Provider may monitor the Fund's compliance with the Warranty Agreement solely to protect the interests of the Warranty Provider and not the Fund's shareholders. The fee paid to the Warranty Provider is an annual fee of 0.60% of the average daily net assets of the Fund. If the Fund is required to make a complete and irreversible allocation of its assets to the debt portfolio, the Warranty Fee will thereafter be reduced to 0.35% of the average daily net assets of the Fund. - -------------------------------------------------------------------------------- SECURITIES VALUATION. The Fund calculates the net asset value of each class of shares based upon the net asset value of the Underlying Fund. For the Underlying Fund, the net asset value per share for a class of shares is determined as of the close of the New York Stock Exchange (the "Exchange"), normally 4:00 P.M. Eastern time, on each day the Exchange is open for trading by dividing the value of the Underlying Fund's net assets attributable to that class by the number of shares of that class outstanding on that day. To determine net asset values, the Underlying Fund's assets are valued primarily on the basis of current market quotations. Long term debt instruments having a remaining maturity in excess of sixty days will be valued at the mean between the "bid" and "asked" prices. "Money market-type" debt instruments with remaining maturities of sixty days or less are valued at cost adjusted by the amortization of discount or premium to maturity, or amortized cost, which approximates market value. Securities held by the Fund and/or an Underlying Fund for which market quotations are not readily available are valued at their fair value. Securities whose values have been materially affected by what the Manager identifies as a significant event occurring before the Fund and/or Underlying Fund's assets are valued but after the close of their respective exchanges will be fair valued. Fair value is determined in good faith using consistently applied procedures under the supervision of the Fund and, when applicable, Underlying Fund's Board of Trustees. 31 | OPPENHEIMER PRINCIPAL PROTECTED MAIN STREET FUND III NOTES TO FINANCIAL STATEMENTS Unaudited / Continued - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 1. SIGNIFICANT ACCOUNTING POLICIES Continued INVESTMENT IN OPPENHEIMER INSTITUTIONAL MONEY MARKET FUND. The Fund is permitted to invest daily available cash balances in an affiliated money market fund. The Fund may invest the available cash in Class E shares of Oppenheimer Institutional Money Market Fund ("IMMF") to seek current income while preserving liquidity. IMMF is a registered open-end management investment company, regulated as a money market fund under the Investment Company Act of 1940, as amended. The Manager is also the investment adviser of IMMF. The Fund's investment in IMMF is included in the Statement of Investments. As a shareholder, the Fund is subject to its proportional share of IMMF's Class E expenses, including its management fee. The Manager will waive fees and/or reimburse Fund expenses in an amount equal to the indirect management fees incurred through the Fund's investment in IMMF. - -------------------------------------------------------------------------------- JOINT REPURCHASE AGREEMENTS. Pursuant to an Exemptive Order issued by the Securities and Exchange Commission, the Fund, along with other affiliated funds advised by the Manager, may transfer uninvested cash balances into joint trading accounts on a daily basis. These balances are invested in one or more repurchase agreements. Securities pledged as collateral for repurchase agreements are held by a custodian bank until the agreements mature. Each agreement requires that the market value of the collateral be sufficient to cover payments of interest and principal. If the seller of the agreement defaults and the value of the collateral declines, or if the seller enters an insolvency proceeding, realization of the value of the collateral by the Fund may be delayed or limited. - -------------------------------------------------------------------------------- INVESTMENTS WITH OFF-BALANCE SHEET RISK. The Fund enters into financial instrument transactions (such as swaps, futures, options and other derivatives) that may have off-balance sheet market risk. Off-balance sheet market risk exists when the maximum potential loss on a particular financial instrument is greater than the value of such financial instrument, as reflected in the Fund's Statement of Assets and Liabilities. - -------------------------------------------------------------------------------- ALLOCATION OF INCOME, EXPENSES, GAINS AND LOSSES. Income, expenses (other than those attributable to a specific class), gains and losses are allocated on a daily basis to each class of shares based upon the relative proportion of net assets represented by such class. Operating expenses directly attributable to a specific class are charged against the operations of that class. - -------------------------------------------------------------------------------- FEDERAL TAXES. The Fund intends to comply with provisions of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all of its investment company taxable income, including any net realized gain on investments not offset by capital loss carryforwards, if any, to shareholders. Therefore, no federal income or excise tax provision is required. The Fund files income tax returns in U.S. federal and applicable state jurisdictions. The statute of limitations on the Fund's tax return filings generally remain open for the three preceding fiscal reporting period ends. Net investment income (loss) and net realized gain (loss) may differ for financial statement and tax purposes. The character of dividends and distributions made during the 32 | OPPENHEIMER PRINCIPAL PROTECTED MAIN STREET FUND III fiscal year from net investment income or net realized gains may differ from their ultimate characterization for federal income tax purposes.Also,due to timing of dividends and distributions,the fiscal year in which amounts are distributed may differ from the fiscal year in which the income or net realized gain was recorded by the Fund. During the fiscal year ended August 31,2007,the Fund utilized $909,112 of capital loss carryforward to offset capital gains realized in that fiscal year. The approximate aggregate cost of securities and other investments and the composition of unrealized appreciation and depreciation of securities and other investments for federal income tax purposes as of February 29,2008 are noted below.The primary difference between book and tax appreciation or depreciation of securities and other investments,if applicable,is attributable to the tax deferral of losses. Federal tax cost of securities $ 68,055,122 Federal tax cost of other investments 4,840,543 ------------ Total federal tax cost $ 72,895,665 ============ Gross unrealized appreciation $ 1,190,183 Gross unrealized depreciation (1,310,040) ------------ Net unrealized depreciation $ (119,857) ============ - -------------------------------------------------------------------------------- TRUSTEES' COMPENSATION. The Board of Trustees has adopted a compensation deferral plan for independent trustees that enables trustees to elect to defer receipt of all or a portion of the annual compensation they are entitled to receive from the Fund. For purposes of determining the amount owed to the Trustee under the plan, deferred amounts are treated as though equal dollar amounts had been invested in shares of the Fund or in other Oppenheimer funds selected by the Trustee. The Fund purchases shares of the funds selected for deferral by the Trustee in amounts equal to his or her deemed investment, resulting in a Fund asset equal to the deferred compensation liability. Such assets are included as a component of "Other" within the asset section of the Statement of Assets and Liabilities. Deferral of trustees' fees under the plan will not affect the net assets of the Fund, and will not materially affect the Fund's assets, liabilities or net investment income per share. Amounts will be deferred until distributed in accordance to the compensation deferral plan. - -------------------------------------------------------------------------------- DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions to shareholders, which are determined in accordance with income tax regulations and may differ from U.S. generally accepted accounting principles, are recorded on the ex-dividend date. 33 | OPPENHEIMER PRINCIPAL PROTECTED MAIN STREET FUND III NOTES TO FINANCIAL STATEMENTS Unaudited / Continued - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 1. SIGNIFICANT ACCOUNTING POLICIES Continued Income and capital gain distributions, if any, are declared and paid annually or at other times as deemed necessary by the Manager. - -------------------------------------------------------------------------------- INVESTMENT INCOME. Dividend income is recorded on the ex-dividend date or upon ex-dividend notification in the case of certain foreign dividends where the ex-dividend date may have passed. Non-cash dividends included in dividend income, if any, are recorded at the fair market value of the securities received. Interest income is recognized on an accrual basis. Discount and premium, which are included in interest income on the Statement of Operations, are amortized or accreted daily. - -------------------------------------------------------------------------------- CUSTODIAN FEES. "Custodian fees and expenses" in the Statement of Operations may include interest expense incurred by the Fund on any cash overdrafts of its custodian account during the period. Such cash overdrafts may result from the effects of failed trades in portfolio securities and from cash outflows resulting from unanticipated shareholder redemption activity. The Fund pays interest to its custodian on such cash overdrafts, to the extent they are not offset by positive cash balances maintained by the Fund, at a rate equal to the Federal Funds Rate plus 0.50%. The "Reduction to custodian expenses" line item, if applicable, represents earnings on cash balances maintained by the Fund during the period. Such interest expense and other custodian fees may be paid with these earnings. - -------------------------------------------------------------------------------- SECURITY TRANSACTIONS. Security transactions are recorded on the trade date. Realized gains and losses on securities sold are determined on the basis of identified cost. - -------------------------------------------------------------------------------- INDEMNIFICATIONS. The Fund's organizational documents provide current and former trustees and officers with a limited indemnification against liabilities arising in connection with the performance of their duties to the Fund. In the normal course of business, the Fund may also enter into contracts that provide general indemnifications. The Fund's maximum exposure under these arrangements is unknown as this would be dependent on future claims that may be made against the Fund. The risk of material loss from such claims is considered remote. - -------------------------------------------------------------------------------- OTHER. The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of increases and decreases in net assets from operations during the reporting period.

PURCHASES AND SALES OF SECURITIES The aggregate cost of purchases and proceeds from sales of securities,other than short-term obligations and investments in IMMF,for the six months ended February 29,2008, were as follows: PURCHASES SALES - ------------------------------------------------------------- Investment securities $ 26,345,805 $ 46,751,472 U.S. government and government agency obligations 44,700,481 24,860,929 - -------------------------------------------------------------------------------- 4. FEES AND OTHER TRANSACTIONS WITH AFFILIATES MANAGEMENT FEES. Under the investment advisory agreement, management fees paid to the Manager were in accordance with the investment advisory agreement with the Fund which provides for a fee at an annual rate of 0.50% of the average annual net assets of the Fund. That fee will apply during the Warranty Period and the Post-Warranty Period. The management fee shall be reduced to 0.40% per annum of average annual net assets of the Fund in any month during the Warranty Period following a month where the Fund's 35 | OPPENHEIMER PRINCIPAL PROTECTED MAIN STREET FUND III NOTES TO FINANCIAL STATEMENTS Unaudited / Continued - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 4. FEES AND OTHER TRANSACTIONS WITH AFFILIATES Continued investment in equity securities (including shares of the Underlying Fund) is, on average, less than 10% of net assets. If during the Warranty Period 100% of the Fund's assets are completely and irreversibly invested in the debt portfolio, the management fee will be at an annual rate of 0.25% of the average annual net assets of the Fund, and if that occurs the Manager will further reduce its management fee to the extent necessary so that expenses after waivers and reductions to the Fund (other than extraordinary expenses such as litigation costs) do not exceed 1.30% for Class A shares, 2.05% for Class B shares, 2.05% for Class C shares and 1.55% for Class N shares. However, if this reduction in the management fee is not sufficient to reduce expenses after waivers and reductions to these limits, the Manager is not required to subsidize Fund expenses to assure that expenses do not exceed those limits. Furthermore, if expenses exceed these expense limits, the Warranty Amount will be reduced by any expenses that exceed those limits. - -------------------------------------------------------------------------------- ADMINISTRATION SERVICE FEES. The Fund pays the Manager a fee of $1,500 per year for preparing and filing the Fund's tax returns. - -------------------------------------------------------------------------------- TRANSFER AGENT FEES. OppenheimerFunds Services ("OFS"), a division of the Manager, acts as the transfer and shareholder servicing agent for the Fund. The Fund pays OFS a per account fee. For the six months ended February 29, 2008, the Fund paid $22,093 to OFS for services to the Fund. - -------------------------------------------------------------------------------- DISTRIBUTION AND SERVICE PLAN (12b-1) FEES. Under its General Distributor's Agreement with the Fund, OppenheimerFunds Distributor, Inc. (the "Distributor") acts as the Fund's principal underwriter in the continuous public offering of the Fund's classes of shares. - -------------------------------------------------------------------------------- SERVICE PLAN FOR CLASS A SHARES. The Fund has adopted a Service Plan (the "Plan") for Class A shares under Rule 12b-1 of the Investment Company Act of 1940. Under the Plan, the Fund reimburses the Distributor for a portion of its costs incurred for services provided to accounts that hold Class A shares. Reimbursement is made periodically at an annual rate of up to 0.25% of the average annual net assets of Class A shares of the Fund. The Distributor currently uses all of those fees to pay dealers, brokers, banks and other financial institutions periodically for providing personal service and maintenance of accounts of their customers that hold Class A shares. Any unreimbursed expenses the Distributor incurs with respect to Class A shares in any fiscal year cannot be recovered in subsequent periods. Fees incurred by the Fund under the Plan are detailed in the Statement of Operations. - -------------------------------------------------------------------------------- DISTRIBUTION AND SERVICE PLANS FOR CLASS B, CLASS C AND CLASS N SHARES. The Fund has adopted Distribution and Service Plans (the "Plans") for Class B, Class C and Class N shares under Rule 12b-1 of the Investment Company Act of 1940 to compensate the Distributor for its services in connection with the distribution of those shares and servicing accounts. Under the Plans, the Fund pays the Distributor an annual asset-based sales 36 | OPPENHEIMER PRINCIPAL PROTECTED MAIN STREET FUND III charge of 0.75% on Class B and Class C shares and 0.25% on Class N shares. The Distributor also receives a service fee of 0.25% per year under each plan. If either the Class B, Class C or Class N plan is terminated by the Fund or by the shareholders of a class, the Board of Trustees and its independent trustees must determine whether the Distributor shall be entitled to payment from the Fund of all or a portion of the service fee and/or asset-based sales charge in respect to shares sold prior to the effective date of such termination. The Distributor's aggregate uncompensated expenses under the Plans at December 31, 2007 for Class B, Class C and Class N shares were $357,552, $23,845 and $12,153, respectively. Fees incurred by the Fund under the Plans are detailed in the Statement of Operations. - -------------------------------------------------------------------------------- SALES CHARGES. Front-end sales charges and contingent deferred sales charges ("CDSC") do not represent expenses of the Fund. They are deducted from the proceeds of sales of Fund shares prior to investment or from redemption proceeds prior to remittance, as applicable. The sales charges retained by the Distributor from the sale of shares and the CDSC retained by the Distributor on the redemption of shares is shown in the following table for the period indicated. CLASS A CLASS B CLASS C CLASS N CLASS A CONTINGENT CONTINGENT CONTINGENT CONTINGENT FRONT-END DEFERRED DEFERRED DEFERRED DEFERRED SALES CHARGES SALES CHARGES SALES CHARGES SALES CHARGES SALES CHARGES SIX MONTHS RETAINED BY RETAINED BY RETAINED BY RETAINED BY RETAINED BY ENDED DISTRIBUTOR DISTRIBUTOR DISTRIBUTOR DISTRIBUTOR DISTRIBUTOR - --------------------------------------------------------------------------------------------------------------------- February 29,2008 $ -- $ 3,068 $ 12,675 $ -- $ -- - --------------------------------------------------------------------------------------------------------------------- WAIVERS AND REIMBURSEMENTS OF EXPENSES. The Manager will reimburse the Fund for expenses equal to the Underlying Fund expenses paid by the Fund as a shareholder of the Underlying Fund. That expense reimbursement will fluctuate as the Fund's allocation between the Underlying Fund and the debt portfolio changes. During the six months ended February 29, 2008, the Manager reimbursed the Fund $85,441 for such Underlying Fund expenses. OFS has voluntarily agreed to limit transfer and shareholder servicing agent fees for all classes to 0.35% of average annual net assets per class. This undertaking may be amended or withdrawn at any time. The Manager will waive fees and/or reimburse Fund expenses in an amount equal to the indirect management fees incurred through the Fund's investment in IMMF. During the six months ended February 29, 2008, the Manager waived $3,012 for IMMF management fees. - -------------------------------------------------------------------------------- 5. FUTURES CONTRACTS A futures contract is a commitment to buy or sell a specific amount of a commodity or financial instrument at a negotiated price on a stipulated future date. The Fund may buy and sell futures contracts on the Standard and Poor's 500 Composite Stock Price Index. The Fund may also buy or write put or call options on these futures contracts. 37 | OPPENHEIMER PRINCIPAL PROTECTED MAIN STREET FUND III NOTES TO FINANCIAL STATEMENTS Unaudited / Continued - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 5. FUTURES CONTRACTS Continued Futures contracts traded on a commodities or futures exchange will be valued at the final settlement price or official closing price on the principal exchange as reported by such principal exchange at its trading session ending at, or most recently prior to, the time when the Fund's assets are valued. Upon entering into a futures contract, the Fund is required to deposit either cash or securities (initial margin) in an amount equal to a certain percentage of the contract value. Subsequent payments (variation margin) are made or received by the Fund each day. The variation margin payments are equal to the daily changes in the contract value and are recorded as unrealized gains and losses. Futures contracts are reported on a schedule following the Statement of Investments. Securities held in collateralized accounts to cover initial margin requirements on open futures contracts are noted in the Statement of Investments. Cash held by the broker to cover initial margin requirements on open futures contracts and the receivable and/or payable for the daily mark to market for the variation margin are noted in the Statement of Assets and Liabilities. The net change in unrealized appreciation and depreciation is reported in the Statement of Operations. Realized gains (losses) are reported in the Statement of Operations at the closing or expiration of futures contracts. Risks of entering into futures contracts (and related options) include the possibility that there may be an illiquid market where the Fund is unable to liquidate the contract or enter into an offsetting position and, if used for hedging purposes, the risk that the price of the contract will correlate imperfectly with the prices of the Fund's securities. - -------------------------------------------------------------------------------- 6. SECURITIES LENDING The Fund lends portfolio securities from time to time in order to earn additional income in the form of fees or interest on securities received as collateral or the investment of any cash received as collateral. The loans are secured by collateral (either securities, letters of credit, or cash) in an amount not less than 100% of the market value of the loaned securities during the period of the loan. The market value of the loaned securities is determined at the close of each business day and any additional required collateral is delivered to the Fund on the next business day. If the borrower defaults on its obligation to return the securities loaned because of insolvency or other reasons, the Fund could experience delays and cost in recovering the securities loaned or in gaining access to the collateral. The Fund continues to receive the economic benefit of interest or dividends paid on the securities loaned in the form of a substitute payment received from the borrower and recognizes the gain or loss in the fair value of the securities loaned that may occur during the term of the loan. The Fund has the right under the lending agreement to recover the securities from the borrower on demand. As of February 29, 2008, the Fund had on loan securities valued at $13,303,494. Collateral of $13,340,586 was received for the loans, all of which was received in cash and subsequently invested in approved instruments. 38 | OPPENHEIMER PRINCIPAL PROTECTED MAIN STREET FUND III - -------------------------------------------------------------------------------- 7. RECENT ACCOUNTING PRONOUNCEMENT In September 2006, Financial Accounting Standards Board ("FASB") issued Statement of Financial Accounting Standards ("SFAS") No. 157, Fair Value Measurements. This standard establishes a single authoritative definition of fair value, sets out a framework for measuring fair value and expands disclosures about fair value measurements. SFAS No. 157 applies to fair value measurements already required or permitted by existing standards. SFAS No. 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007, and interim periods within those fiscal years. As of February 29, 2008, the Manager does not believe the adoption of SFAS No. 157 will materially impact the financial statement amounts; however, additional disclosures may be required about the inputs used to develop the measurements and the effect of certain of the measurements on changes in net assets for the period. 39 | OPPENHEIMER PRINCIPAL PROTECTED MAIN STREET FUND III PORTFOLIO PROXY VOTING POLICIES AND PROCEDURES; UPDATES TO STATEMENTS OF INVESTMENTS Unaudited - -------------------------------------------------------------------------------- The Fund has adopted Portfolio Proxy Voting Policies and Procedures under which the Fund votes proxies relating to securities ("portfolio proxies") held by the Fund.

SIGNIFICANT ACCOUNTING POLICIES Oppenheimer Main Street Fund (the "Fund") is a separate series of Oppenheimer Main Street Funds, Inc., an open-end management investment company registered under the Investment Company Act of 1940, as amended. The Fund's investment objective is to seek a high total return. The Fund's investment adviser is OppenheimerFunds, Inc. (the "Manager"). The Fund offers Class A, Class B, Class C, Class N and Class Y shares. Class A shares are sold at their offering price, which is normally net asset value plus a front-end sales charge. Class B, Class C and Class N shares are sold without a front-end sales charge but may be subject to a contingent deferred sales charge ("CDSC"). Class N shares are sold only through retirement plans. Retirement plans that offer Class N shares may impose charges on those accounts. Class Y shares are sold to certain institutional investors without either a front-end sales charge or a CDSC, however, the institutional investor may impose charges on those accounts. All classes of shares have identical rights and voting privileges with respect to the Fund in general and exclusive voting rights on matters that affect that class alone. Earnings, net assets and net asset value per share may differ due to each class having its own expenses, such as transfer and shareholder servicing agent fees and shareholder communications, directly attributable to that class. Class A, B, C and N have separate distribution and/or service plans. No such plan has been adopted for Class Y shares. Class B shares will automatically convert to Class A shares 72 months after the date of purchase. The following is a summary of significant accounting policies consistently followed by the Fund. - -------------------------------------------------------------------------------- SECURITIES VALUATION. The Fund calculates the net asset value of its shares as of the close of the New York Stock Exchange (the "Exchange"), normally 4:00 P.M. Eastern time, on each day the Exchange is open for trading. Securities may be valued primarily using dealer-supplied valuations or a portfolio pricing service authorized by the Board of Directors. Securities traded on a registered U.S. securities exchange are valued based on the last sale price of the security traded on that exchange prior to the time when the Fund's assets are valued. Securities whose principal exchange is NASDAQ R are valued based on the closing price reported by NASDAQ prior to the time when the Fund's assets are valued. In the absence of a sale, the security is valued at the last sale price on the prior trading day, if it is within the spread of the closing "bid" and "asked" prices, and if not, at the closing bid price. Securities traded on foreign exchanges are valued based on the last sale price on the principal exchange on which the security is traded, as identified by the portfolio pricing service, prior to the time when the Fund's assets are valued. In the absence of a sale, the security is valued at the official closing price on the principal exchange. Corporate, government and municipal debt instruments having a remaining maturity in excess of sixty days and all mortgage-backed securities, collateralized mortgage obligations and other asset-backed securities will be valued at the mean between the "bid" and "asked" prices. Securities for which market quotations are not readily available are valued at their fair value. Securities whose values have been materially affected 63 | OPPENHEIMER PRINCIPAL PROTECTED MAIN STREET FUND III OPPENHEIMER MAIN STREET FUND (UNDERLYING FUND) NOTES TO FINANCIAL STATEMENTS Unaudited / Continued - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 1. SIGNIFICANT ACCOUNTING POLICIES Continued - -------------------------------------------------------------------------------- by what the Manager identifies as a significant event occurring before the Fund's assets are valued but after the close of their respective exchanges will be fair valued. Fair value is determined in good faith using consistently applied procedures under the supervision of the Board of Directors. Shares of a registered investment company that are not traded on an exchange are valued at the acquired investment company's net asset value per share. "Money market-type" debt instruments with remaining maturities of sixty days or less are valued at cost adjusted by the amortization of discount or premium to maturity (amortized cost), which approximates market value. - -------------------------------------------------------------------------------- INVESTMENT IN OPPENHEIMER INSTITUTIONAL MONEY MARKET FUND. The Fund is permitted to invest daily available cash balances in an affiliated money market fund. The Fund may invest the available cash in Class E shares of Oppenheimer Institutional Money Market Fund ("IMMF") to seek current income while preserving liquidity. IMMF is a registered open-end management investment company, regulated as a money market fund under the Investment Company Act of 1940, as amended. The Manager is also the investment adviser of IMMF. The Fund's investment in IMMF is included in the Statement of Investments. As a shareholder, the Fund is subject to its proportional share of IMMF's Class E expenses, including its management fee. The Manager will waive fees and/or reimburse Fund expenses in an amount equal to the indirect management fees incurred through the Fund's investment in IMMF. - -------------------------------------------------------------------------------- JOINT REPURCHASE AGREEMENTS. Pursuant to an Exemptive Order issued by the Securities and Exchange Commission, the Fund, along with other affiliated funds advised by the Manager, may transfer uninvested cash balances into joint trading accounts on a daily basis. These balances are invested in one or more repurchase agreements. Securities pledged as collateral for repurchase agreements are held by a custodian bank until the agreements mature. Each agreement requires that the market value of the collateral be sufficient to cover payments of interest and principal. If the seller of the agreement defaults and the value of the collateral declines, or if the seller enters an insolvency proceeding, realization of the value of the collateral by the Fund may be delayed or limited. - -------------------------------------------------------------------------------- ALLOCATION OF INCOME, EXPENSES, GAINS AND LOSSES. Income, expenses (other than those attributable to a specific class), gains and losses are allocated on a daily basis to each class of shares based upon the relative proportion of net assets represented by such class. Operating expenses directly attributable to a specific class are charged against the operations of that class. - -------------------------------------------------------------------------------- FEDERAL TAXES. The Fund intends to comply with provisions of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all of its investment company taxable income, including any net realized gain on investments not offset by capital loss carryforwards, if any, to shareholders. Therefore, no federal income or excise tax provision is required. The Fund files income tax returns in U.S. federal and 64 | OPPENHEIMER PRINCIPAL PROTECTED MAIN STREET FUND III applicable state jurisdictions. The statute of limitations on the Fund's tax return filings generally remain open for the three preceding fiscal reporting period ends. Net investment income (loss) and net realized gain (loss) may differ for financial statement and tax purposes. The character of dividends and distributions made during the fiscal year from net investment income or net realized gains may differ from their ultimate characterization for federal income tax purposes. Also, due to timing of dividends and distributions, the fiscal year in which amounts are distributed may differ from the fiscal year in which the income or net realized gain was recorded by the Fund. As of February 29, 2008, the Fund had available for federal income tax purposes an estimated capital loss carryforward of zero. This estimated capital loss carryforward represents carryforward as of the end of the last fiscal year, increased for losses deferred under tax accounting rules to the current fiscal year and is increased or decreased by capital losses or gains realized in the first six months of the current fiscal year. During the six months ended February 29, 2008, it is estimated that the Fund will utilize $23,186 of capital loss carryforward to offset realized capital gains. During the fiscal year ended August 31, 2007, the Fund utilized $489,935 of capital loss carryforward to offset capital gains realized in that fiscal year. As of August 31, 2007, the Fund had available for federal income tax purposes post-October foreign currency losses of $23,186. The approximate aggregate cost of securities and other investments and the composition of unrealized appreciation and depreciation of securities and other investments for federal income tax purposes as of February 29, 2008 are noted below. The primary difference between book and tax appreciation or depreciation of securities and other investments, if applicable, is attributable to the tax deferral of losses. Federal tax cost of securities $ 9,186,746,307 =============== Gross unrealized appreciation $ 1,353,336,898 Gross unrealized depreciation (568,079,566) --------------- Net unrealized appreciation $ 785,257,332 =============== - -------------------------------------------------------------------------------- DIRECTORS' COMPENSATION. The Board of Directors has adopted a compensation deferral plan for independent directors that enables directors to elect to defer receipt of all or a portion of the annual compensation they are entitled to receive from the Fund. For purposes of determining the amount owed to the Director under the plan, deferred amounts are treated as though equal dollar amounts had been invested in shares of the Fund or in other Oppenheimer funds selected by the Director. The Fund purchases shares of the funds selected for deferral by the Director in amounts equal to his or her deemed investment, resulting in a Fund asset equal to the deferred compensation liability. Such assets are included as a component of "Other" within the asset section of the Statement of Assets and Liabilities. Deferral of directors' fees under the plan will not affect the net assets of the Fund, and will not materially affect the Fund's assets, liabilities or net investment income per share. Amounts will be deferred until distributed in accordance to the compensation deferral plan. 65 | OPPENHEIMER PRINCIPAL PROTECTED MAIN STREET FUND III OPPENHEIMER MAIN STREET FUND (UNDERLYING FUND) NOTES TO FINANCIAL STATEMENTS Unaudited / Continued - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 1. SIGNIFICANT ACCOUNTING POLICIES Continued DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions to shareholders, which are determined in accordance with income tax regulations and may differ from U.S. generally accepted accounting principles, are recorded on the ex-dividend date. Income and capital gain distributions, if any, are declared and paid annually or at other times as deemed necessary by the Manager. - -------------------------------------------------------------------------------- INVESTMENT INCOME. Dividend income is recorded on the ex-dividend date or upon ex-dividend notification in the case of certain foreign dividends where the ex-dividend date may have passed. Non-cash dividends included in dividend income, if any, are recorded at the fair market value of the securities received. Interest income is recognized on an accrual basis. Discount and premium, which are included in interest income on the Statement of Operations, are amortized or accreted daily. - -------------------------------------------------------------------------------- CUSTODIAN FEES. "Custodian fees and expenses" in the Statement of Operations may include interest expense incurred by the Fund on any cash overdrafts of its custodian account during the period. Such cash overdrafts may result from the effects of failed trades in portfolio securities and from cash outflows resulting from unanticipated shareholder redemption activity. The Fund pays interest to its custodian on such cash overdrafts, to the extent they are not offset by positive cash balances maintained by the Fund, at a rate equal to the Federal Funds Rate plus 0.50%. The "Reduction to custodian expenses" line item, if applicable, represents earnings on cash balances maintained by the Fund during the period. Such interest expense and other custodian fees may be paid with these earnings. - -------------------------------------------------------------------------------- SECURITY TRANSACTIONS. Security transactions are recorded on the trade date. Realized gains and losses on securities sold are determined on the basis of identified cost. - -------------------------------------------------------------------------------- INDEMNIFICATIONS. The Fund's organizational documents provide current and former directors and officers with a limited indemnification against liabilities arising in connection with the performance of their duties to the Fund. In the normal course of business, the Fund may also enter into contracts that provide general indemnifications. The Fund's maximum exposure under these arrangements is unknown as this would be dependent on future claims that may be made against the Fund. The risk of material loss from such claims is considered remote. - -------------------------------------------------------------------------------- OTHER. The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of increases and decreases in net assets from operations during the reporting period. Actual results could differ from those estimates. 66 | OPPENHEIMER PRINCIPAL PROTECTED MAIN STREET FUND III - -------------------------------------------------------------------------------- 2.SHARES OF CAPITAL STOCK The Fund has authorized 840 million shares of $.01 par value capital stock.

Fees incurred by the Fund under the Plan are detailed in the Statement of Operations. 68 | OPPENHEIMER PRINCIPAL PROTECTED MAIN STREET FUND III - -------------------------------------------------------------------------------- DISTRIBUTION AND SERVICE PLANS FOR CLASS B, CLASS C AND CLASS N SHARES.

Securities that are illiquid are marked with an applicable footnote on the Statement of Investments. 69 | OPPENHEIMER PRINCIPAL PROTECTED MAIN STREET FUND III OPPENHEIMER MAIN STREET FUND (UNDERLYING FUND) NOTES TO FINANCIAL STATEMENTS Unaudited / Continued - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 6. SECURITIES LENDING The Fund lends portfolio securities from time to time in order to earn additional income in the form of fees or interest on securities received as collateral or the investment of any cash received as collateral. The loans are secured by collateral (either securities, letters of credit, or cash) in an amount not less than 100% of the market value of the loaned securities during the period of the loan. The market value of the loaned securities is determined at the close of each business day and any additional required collateral is delivered to the Fund on the next business day. If the borrower defaults on its obligation to return the securities loaned because of insolvency or other reasons, the Fund could experience delays and cost in recovering the securities loaned or in gaining access to the collateral. The Fund continues to receive the economic benefit of interest or dividends paid on the securities loaned in the form of a substitute payment received from the borrower and recognizes the gain or loss in the fair value of the securities loaned that may occur during the term of the loan. The Fund has the right under the lending agreement to recover the securities from the borrower on demand. As of February 29, 2008, the Fund had on loan securities valued at $524,178,455. Collateral of $558,478,892 was received for the loans, all of which was received in cash and subsequently invested in approved instruments. - -------------------------------------------------------------------------------- 7. RECENT ACCOUNTING PRONOUNCEMENT In September 2006, Financial Accounting Standards Board ("FASB") issued Statement of Financial Accounting Standards ("SFAS") No. 157, Fair Value Measurements. This standard establishes a single authoritative definition of fair value, sets out a framework for measuring fair value and expands disclosures about fair value measurements. SFAS No. 157 applies to fair value measurements already required or permitted by existing standards. SFAS No. 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007, and interim periods within those fiscal years. As of February 29, 2008, the Manager does not believe the adoption of SFAS No. 157 will materially impact the financial statement amounts; however, additional disclosures may be required about the inputs used to develop the measurements and the effect of certain of the measurements on changes in net assets for the period. 70 | OPPENHEIMER PRINCIPAL PROTECTED MAIN STREET FUND III ITEM 2.

The Fund's Governance Committee (the "Committee") will evaluate potential Board candidates to assess their qualifications. The Committee shall have the authority, upon approval of the Board, to retain an executive search firm to assist in this effort. The Committee may consider recommendations by business and personal contacts of current Board members and by executive search firms which the Committee may engage from time to time and may also consider shareholder recommendations. The Committee may consider the advice and recommendation of the Funds' investment manager and its affiliates in making the selection. 2. The Committee shall screen candidates for Board membership. The Committee has not established specific qualifications that it believes must be met by a trustee nominee. In evaluating trustee nominees, the Committee considers, among other things, an individual's background, skills, and experience; whether the individual is an "interested person" as defined in the Investment Company Act of 1940; and whether the individual would be deemed an "audit committee financial expert" within the meaning of applicable SEC rules. The Committee also considers whether the individual's background, skills, and experience will complement the background, skills, and experience of other nominees and will contribute to the Board. There are no differences in the manner in which the Committee evaluates nominees for trustees based on whether the nominee is recommended by a shareholder. 3. The Committee may consider nominations from shareholders for the Board at such times as the Committee meets to consider new nominees for the Board. The Committee shall have the sole discretion to determine the candidates to present to the Board and, in such cases where required, to shareholders. Recommendations for trustee nominees should, at a minimum, be accompanied by the following: o the name, address, and business, educational, and/or other pertinent background of the person being recommended; o a statement concerning whether the person is an "interested person" as defined in the Investment Company Act of 1940; o any other information that the Funds would be required to include in a proxy statement concerning the person if he or she was nominated; and o the name and address of the person submitting the recommendation and, if that person is a shareholder, the period for which that person held Fund shares. The recommendation also can include any additional information which the person submitting it believes would assist the Committee in evaluating the recommendation. 4. Shareholders should note that a person who owns securities issued by Massachusetts Mutual Life Insurance Company (the parent company of the Funds' investment adviser) would be deemed an "interested person" under the Investment Company Act of 1940. In addition, certain other relationships with Massachusetts Mutual Life Insurance Company or its subsidiaries, with registered broker-dealers, or with the Funds' outside legal counsel may cause a person to be deemed an "interested person." 5. Before the Committee decides to nominate an individual as a trustee, Committee members and other directors customarily interview the individual in person. In addition, the individual customarily is asked to complete a detailed questionnaire which is designed to elicit information which must be disclosed under SEC and stock exchange rules and to determine whether the individual is subject to any statutory disqualification from serving as a trustee of a registered investment company. ITEM 11. CONTROLS AND PROCEDURES. Based on their evaluation of the registrant's disclosure controls and procedures (as defined in rule 30a-3(c) under the Investment Company Act of 1940 (17 CFR 270.30a-3(c)) as of 02/29/2008, the registrant's principal executive officer and principal financial officer found the registrant's disclosure controls and procedures to provide reasonable assurances that information required to be disclosed by the registrant in the reports that it files under the Securities Exchange Act of 1934 (a) is accumulated and communicated to registrant's management, including its principal executive officer and principal financial officer, to allow timely decisions regarding required disclosure, and (b) is recorded, processed, summarized and reported, within the time periods specified in the rules and forms adopted by the U.S. Securities and Exchange Commission. There have been no changes in the registrant's internal controls over financial reporting that occurred during the registrant's second fiscal quarter of the period covered by this report that have materially affected, or are reasonably likely to materially affect, the registrant's internal control over financial reporting.
