This report covers the Fund's performance for the semi-annual period ended May 31, 2008. The Fund's investment objective is to provide a high level of after-tax total return with an emphasis on current distributions paid to shareholders. Fiduciary Asset Management, LLC ("FAMCO"), the Fund's sub-adviser, seeks to achieve that objective by investing at least 80% of the Fund's managed assets in master limited partnership ("MLP") entities, which can provide shareholders with attractive tax-deferred income. FAMCO manages a wide range of institutional products and is one of the leading managers of hedged equity investments. As of May 31, 2008, FAMCO managed or supervised approximately $17.8 billion in assets. All Fund returns cited - whether based on net asset value ("NAV") or market price - assume the reinvestment of all distributions. For the six-month period ending May 31, 2008, the Fund provided a total return based on market price of 3.53% and a return of -2.07% based on NAV. As of May 31, 2008, the Fund's last closing market price of $22.70 represented a premium of 3.65% to the Fund's NAV of $21.90. Past performance is not a guarantee of future results. The market value of the Fund's shares fluctuates from time to time, and it may be higher or lower than the Fund's NAV. On January 2, 2008, the Board of Trustees of the Fund announced that it would increase the quarterly dividend by 1.41% to $0.36 per share, effective with the January 2008 distribution. The Board of Trustees subsequently authorized two additional dividend increases during this fiscal period: a 1.39% increase to $0.365 effective with the April 2008 distribution, and a 1.37% increase to $0.37 per share effective with the July 2008 distribution. This July-declared quarterly dividend level of $0.37 represents an annualized distribution rate of 6.52%, based on the Fund's closing market price of $22.70 on May 31, 2008. Under the Fund's Automatic Dividend Reinvestment Plan (the "Plan"), a shareholder whose Common Shares are registered in his or her own name will have all distributions reinvested automatically unless the shareholder elects to receive cash. Distributions with respect to Common Shares registered in the name of a broker-dealer or other nominee (that is, in "street name") will be reinvested by the broker or nominee in additional Common Shares under the Plan, unless the service is not provided by the broker or nominee or the shareholder elects to receive distributions in cash. The Plan is described in detail on page 24 of the Fund's semi-annual report. When shares trade at a discount to NAV, the Plan takes advantage SemiAnnual Report | May 31, 2008 | 3 FMO | Fiduciary/Claymore MLP Opportunity Fund | Dear Shareholder continued of the discount by reinvesting the quarterly dividend distribution in common shares of the Fund purchased in the market at a price less than NAV. Conversely, when the market price of the Fund's common shares is at a premium above NAV, the Plan reinvests participants' dividends in newly-issued common shares at NAV, subject to an IRS limitation that the purchase price cannot be more than 5% below the market price per share. The Plan provides a cost-effective means to accumulate additional shares and enjoy the benefits of compounding returns over time.

Thomas Futrell Fiduciary/Claymore MLP Opportunity Fund 4 | SemiAnnual Report | May 31, 2008 FMO | Fiduciary/Claymore MLP Opportunity Fund QUESTIONS & ANSWERS| The Fiduciary/Claymore MLP Opportunity Fund (the "Fund") is managed by Fiduciary Asset Management, LLC. ("FAMCO"). In the following interview, Portfolio Manager James J. Cunnane, Jr., CFA, discusses the Fund's performance for the semi-annual period ended May 31, 2008. -------------------------------------------------------------------------------- WILL YOU REMIND US OF THIS FUND'S OBJECTIVE AND INVESTMENT STRATEGY? The Fund's investment objective is to provide a high level of after-tax total return with an emphasis on current distributions paid to shareholders. The total return sought by the Fund includes appreciation in the net asset value ("NAV") of the Fund's common shares and all distributions made by the Fund to its common shareholders, regardless of the tax characterization of such distributions. The Fund has been structured to seek to provide an efficient vehicle through which its shareholders may invest in a portfolio of publicly traded securities of master limited partnerships ("MLPs") and related entities. MLPs combine the tax benefits of limited partnerships with the liquidity of publicly traded securities. The Fund believes that as a result of the tax characterization of cash distributions made by MLPs to their investors, a significant portion of the Fund's income will be tax-deferred, which may allow distributions by the Fund to its shareholders to include high levels of tax-deferred income. Under normal market conditions, we invest at least 80% of the Fund's managed assets in MLP entities, and at least 65% of managed assets in equity securities of MLP entities. MLP entities include affiliates of MLPs that own general partner interests or, in some cases, subordinated units, registered or unregistered common units, or other limited partner units in an MLP. The Fund may also invest in common stocks of large capitalization companies, including companies engaged in the energy, natural resources and real estate sectors. We may employ an option strategy of writing (selling) covered call options on common stocks held in the Fund's portfolio in order to generate current income and gains. Up to 40% of the Fund's managed assets may be invested in unregistered or otherwise restricted securities, which may consist of equity securities of MLP entities and other securities of public and non-public companies, but no more than 20% of its managed assets will be invested in restricted securities issued by non-public companies. -------------------------------------------------------------------------------- HOW WOULD YOU DESCRIBE THE MASTER LIMITED PARTNERSHIP MARKET OVER THE LAST SIX MONTHS? In recent months, MLPs have been in a generally sideways trading pattern but with considerable volatility. This followed a rather dramatic sell-off in the MLP market in the summer of 2007, when there was a significant change in the financial landscape, with much wider credit spreads and a marked decline in investors' risk tolerance. A significant pull-back in late March 2008 was associated with the continued de-levering of the market that included MLPs. After that disruption, MLPs moved back into the same trading range we have seen over the last six to nine months. Using the Alerian MLP Index (the "Index") as a benchmark for the industry, total return for the six-month period ended May 31, 2008, was 1.25%.(1) In the spring of 2008, our analysis indicated that the market for MLPs was as cheap on a fundamental valuation basis as it had been at any time in the last five years. Of necessity, that comparison of valuation over time included only those MLPs that have operated for several years, excluding some of the newer ones with less proven business plans. What we have seen in the last few months is not a break-down in the fundamentals of MLPs, but rather broader market issues impacting investors in MLPs. Throughout the capital markets, there has been an aversion to risk in any form and a pronounced de-levering across asset classes. Some of the larger investors in MLPs, faced with the need to raise cash, sold their MLP investments. This over-supply of MLP equities created a significant downward pressure on MLP pricing. Fundamentals of MLPs, however, remain sound. Most of the seasoned, well managed MLPs have continued to increase earnings, and distributions have been increasing at an annual rate of about 10%. There were three major drivers of performance among specific MLPs over this period. First, prices of most commodities, especially those that relate to energy, have been rising steadily. So, almost any business with a direct interest in commodities, including many MLPs, has performed well. Second, the market's risk aversion has led to a significant flight to quality. This means that those MLPs perceived as being of higher --------------------- 1 The Alerian MLP Index measures the composite performance of the 50 most prominent energy MLPs, and is calculated by Standard & Poor's using a float-adjusted, capitalization-weighted methodology. An Index is unmanaged and it is not possible to invest directly in an index. SemiAnnual Report | May 31, 2008 | 5 FMO | Fiduciary/Claymore MLP Opportunity Fund | QUESTIONS & ANSWERS continued quality and lower risk performed better than others. In general, this means that the largest MLPs performed best. As we analyze the MLP market, we divide the Alerian MLP Index into quintiles on various measures including market capitalization. Over the six months ended May 2008, the average market price of the quintile with the largest market capitalization, $11 billion or more, was up approximately 8.7%. None of the other quintiles produced positive returns on a market price basis. The third big driver of MLP market performance was a major imbalance between supply and demand, as widening credit spreads and investors' decreased risk tolerance created a liquidity crisis. Those MLPs that were in need of new capital and those that had major investors who needed to raise cash by selling assets generally performed poorly. -------------------------------------------------------------------------------- HOW DID THE FUND PERFORM IN THIS MARKET ENVIRONMENT? All Fund returns cited - whether based on NAV or market price - assume the reinvestment of all distributions. For the six-month period ended May 31, 2008, the Fund provided a total return based on market price of 3.53% and a return of -2.07% based on NAV, trailing the Alerian MLP Index by a little over 300 basis points. It should be noted that the broader MLP market return does not reflect the impact of expenses or income taxes. Past performance is not a guarantee of future results. The market value of the shares of closed-end funds fluctuates from time to time, and a fund's market value may be higher or lower than its net asset value. The last closing price of the Fund's shares as of May 31, 2008, was $22.70, representing a 3.65% premium to the NAV of $21.90. On November 30, 2007, the Fund's market price closed at $22.66, which represented a discount of 1.95% to the NAV of $23.11. At its inception in December 2004, the Fund's NAV was $19.10. When comparing market value and NAV performance, it is important to consider the special tax structure of the Fund. For every dollar earned by the Fund, the NAV tends to rise by a smaller amount. That is because the Fund is a taxable entity, meaning the Fund recognizes a deferred tax liability that accrues as the value of its portfolio appreciates. This ensures the Fund's NAV reflects the after-tax value of the unrealized gains in the Fund's portfolio. With that said, the Fund retains those additional assets to manage until it sells the underlying securities, subsequently realizes any gains and finally pays taxes on the sold securities. -------------------------------------------------------------------------------- PLEASE TELL US ABOUT THE FUND'S DISTRIBUTIONS. On January 2, 2008, the Board of Trustees of the Fund announced that it would increase the quarterly dividend by 1.41% to $0.36 per share, effective with the January 2008 distribution. The Board of Trustees subsequently authorized two additional dividend increases during this fiscal period: a 1.39% increase to $0.365 effective with the April 2008 distribution, and a 1.37% increase to $0.37 per share effective with the July 2008 distribution. These dividend increases were made possible by a modification to the Fund's distribution policy announced in December 2006 that better allows the Fund to pass through positive performance of the portfolio to Fund shareholders. We believe the revised policy better aligns it with the Fund's investment objective. The revised policy is consistent with our belief that distributions from a taxable closed-end fund such as this one should reflect the expected long-term after-tax total return potential of the portfolio. Some of the investments under consideration have lower current yields than other possible investments, but we believe they have better prospects for total long-term return. The revised policy enables the Fund to generate distributions from both net investment income and capital appreciation of portfolio securities. This flexibility aligns well with our investment philosophy of managing the portfolio with total return in mind. The new policy gives us the flexibility to purchase for the Fund the securities we consider best overall, even if the net investment income they generate does not fully fund a distribution in a given quarter. -------------------------------------------------------------------------------- HOW IS THE FUND POSITIONED IN TERMS OF SECTORS? Within the MLP category, the two largest sectors by far are midstream gas and midstream oil, which together represent approximately 85% of the Index. As in prior periods, we kept the Fund invested across the MLP market but maintained most of its exposure in these two large sectors. As of May 31, 2008, midstream gas represented 42.3% of long-term investments, and midstream oil represented 37.2%, so together these two large sectors represented 79.5% of long-term investments, somewhat less than the Index. 6 | SemiAnnual Report | May 31, 2008 FMO | Fiduciary/Claymore MLP Opportunity Fund | QUESTIONS & ANSWERS continued -------------------------------------------------------------------------------- WHAT WERE THE MOST SIGNIFICANT FACTORS AFFECTING THE FUND'S PERFORMANCE? The Fund's performance benefited from a significant position in commodity-focused MLPs, particularly coal. We have gradually begun to reduce some of these positions, taking advantage of recent strong performance. The Fund's coal MLPs that performed well include Alliance Holdings GP, L.P. (3.7% of long-term investments) and Alliance Resource Partners, L.P. (0.7% of long-term investments). A significant detriment to performance was the Fund's positioning in terms of market capitalization. We have positioned the Fund with slightly smaller market capitalization than the Index and most competing funds. As mentioned above, the largest MLPs performed best over this period, as they are perceived by investors as being less risky. Another detractor from performance was the Fund's emphasis on MLPs that are oriented toward growth. If you examine distribution growth among the five quintiles of the Index in terms of market capitalization, the smallest MLPs had the greatest growth in distributions and the largest had the least. Similarly, the MLPs with the lowest yields, which generally correlate to highest growth, were the weakest within the Index. Despite strong fundamental performance, in line with our expectations, the equity securities for these MLPs underperformed. To summarize, over this period, the Fund's emphasis on smaller capitalization and higher growth MLPs detracted from performance. We regard this as a temporary situation that relates to the market's risk aversion, and we believe this positioning will benefit the Fund's shareholders over the long term. The largest MLPs in the portfolio in terms of total market capitalization, Kinder Morgan Energy Partners, L.P. (4.3% of long-term investments) and Kinder Morgan Management, LLC (4.1% of long-term investments), made significant contributions to absolute performance; these two related MLPs are largely the same entity but packaged somewhat differently. However, the Fund is underweight in these large MLPs relative to the Index, and that detracted from relative performance. These large MLP entities have tended to perform well when investors become uncomfortable with risk and there is a flight to quality, as in this six-month period. A growth-oriented holding that performed quite well in terms of operations is DCP Midstream Partners, LP (3.1% of long-term investments), a midstream gas company. DCP is a good example of the kind of investment we are seeking for the Fund: we believe it is a solid entity with a sound low-risk business model. However, it performed poorly on a market price basis due to market conditions unrelated to its business. -------------------------------------------------------------------------------- HOW DID THE FUND'S LEVERAGE AFFECT PERFORMANCE DURING THIS PERIOD? The purpose of leverage (borrowing) is to fund the purchase of additional securities that provide increased income and potentially greater appreciation to common shareholders than could be achieved from an unleveraged portfolio. Of course, leverage results in greater NAV volatility and entails more downside risk than an unleveraged portfolio. During the six months ended May 31, 2008, the Fund's leverage represented between 29.4% and 32.7% of managed assets, defined as net assets plus leverage. At the end of the period, leverage was approximately 30% of managed assets. Since leverage adds to performance only when the cost of leverage is less than the return generated by investments, the use of leverage detracted from performance during this period. However, a positive factor for performance relative to competing funds was that the Fund's leverage as a percentage of managed assets was somewhat lower than most of the funds that we consider to be the Fund's peer group. Also, we were fortunate to have our leverage in the commercial paper conduit market, rather than through the issuance of Auction Market Preferred Shares ("AMPS"), a form of leverage used by many closed-end funds. The broad auction-rate preferred securities market has experienced considerable disruption in the past few months, including many failed auctions and increased cost of leverage in some cases. Because of the nature of instruments used for leverage, the Fund's cost of leverage was therefore significantly less than many other funds. Furthermore, we were able to execute swaps against approximately two-thirds of our leverage at very attractive levels, locking in a low cost of leverage for several years. Over the long term, we believe that leverage will contribute to the Fund's performance, as it has in past periods. SemiAnnual Report | May 31, 2008 | 7 FMO | Fiduciary/Claymore MLP Opportunity Fund | QUESTIONS & ANSWERS continued -------------------------------------------------------------------------------- WHAT IS YOUR CURRENT OUTLOOK FOR THE MLP MARKET? We believe that the recent weakness in market prices of MLPs has very little to do with fundamentals. In fact, the MLP market looks robust now, with solid infrastructure spending and sound fundamentals. At current prices, we believe that many MLPs are priced well below their intrinsic value, and we are taking advantage of opportunities to make some investments at attractive prices. As we seek new investments, we remain focused on smaller, faster growing MLPs that have healthy balance sheets, high-quality assets and strong management teams. We believe that MLPs offer a combination of current yield and growth potential that provides greater stability, higher income and better long-term potential than other income-oriented investments such as bonds, utility stocks or real estate investment trusts. MLPs also have a reasonable level of growth potential and tax deferral features. We believe that the correlation to other asset classes will remain low over the next few years as the credit markets settle into more normalized patterns and the acquisition market re-accelerates. 8 | SemiAnnual Report | May 31, 2008 FMO | Fiduciary/Claymore MLP Opportunity Fund | QUESTIONS & ANSWERS continued -------------------------------------------------------------------------------- RISKS AND OTHER CONSIDERATIONS The views expressed in this report reflect those of the portfolio manager and Claymore only through the report period as stated on the cover. These views are subject to change at any time, based on market and other conditions and should not be construed as a recommendation of any kind. The material may also include forward looking statements that involve risk and uncertainty, and there is no guarantee that any predictions will come to pass. There can be no assurance that the Fund will achieve its investment objectives. The value of the Fund will fluctuate with the value of the underlying securities. Historically, closed-end funds often trade at a discount to their net asset value. RISKS OF INVESTING IN MLP UNITS. An investment in MLP units involves risks that differ from a similar investment in equity securities, such as common stock, of a corporation. Holders of MLP units have the rights typically afforded to limited partners in a limited partnership. As compared to common shareholders of a corporation, holders of MLP units have more limited control and limited rights to vote on matters affecting the partnership. There are certain tax risks associated with an investment in MLP units. Additionally, conflicts of interest may exist between common unit holders, subordinated unit holders and the general partner of an MLP; for example a conflict may arise as a result of incentive distribution payments. TAX RISKS OF INVESTING IN EQUITY SECURITIES OF MLPS. There are certain tax risks associated with an investment in MLP units. Much of the benefit the Fund derives from its investment in equity securities of MLPs is a result of MLPs generally being treated as partnerships for U.S. federal income tax purposes. A change in current tax law, or a change in the business of a given MLP, could result in an MLP being treated as a corporation for U.S. federal income tax purposes, which would result in such MLP being required to pay U.S. federal income tax on its taxable income. The classification of an MLP as a corporation for U.S. federal income taxation purposes would have the effect of reducing the amount of cash available for distribution by the MLP and causing any such distributions received by the Fund to be taxed as dividend income. Thus, if any of the MLPs owned by the Fund were treated as corporations for U.S. federal income tax purposes, the after-tax return to the Fund with respect to its investment in such MLPs would be materially reduced, which could cause a substantial decline in the value of the common shares. Because of the Fund's concentration in MLPs, the Fund is not eligible to be treated as a "regulated investment company" under the Internal Revenue Code of 1986, as amended. Instead, the Fund will be treated as a regular corporation for US federal income tax purposes and as a result, unlike most investment companies, will be subject to corporate income tax to the extent the Fund recognizes taxable income. The Fund believes that as a result of the tax characterization of cash distributions made by MLPs, a significant portion of the Fund's income will be tax-deferred, which will allow distributions by the Fund to its shareholders to include high levels of tax-deferred income. However, there can be no assurance in this regard. If this expectation is not realized, the Fund will have a larger corporate income tax expense than expected, which will result in less cash available to distribute to shareholders. EQUITY SECURITIES RISK. Equity risk is the risk that MLP units or other equity securities held by the Fund will fall due to general market or economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate, changes in interest rates, and the particular circumstances and performance of particular companies whose securities the Fund holds. In addition, MLP units or other equity securities held by the Fund may decline in price if the issuer fails to make anticipated distributions or dividend payments because, among other reasons, the issuer experiences a decline in its financial condition. CONCENTRATION RISK. Because the Fund will invest in MLP entities, a substantial portion of which are expected to be engaged primarily in the energy, natural resources and real estate sectors of the economy, such concentration may present more risks than if the Fund were broadly diversified over numerous industries and sectors of the economy RISKS ASSOCIATED WITH OPTIONS ON SECURITIES. There are several risks associated with transactions in options on securities. A decision as to whether, when and how to use options involves the exercise of skill and judgment, and even a well-conceived transaction may be unsuccessful to some degree because of market behavior or unexpected events. As the writer of a covered call option, the Fund forgoes, during the option's life, the opportunity to profit from increases in the market value of the security covering the call option above the sum of the premium and the strike price of the call, but has retained the risk of loss should the price of the underlying security decline. The writer of an option has no control over the time when it may be required to fulfill its obligation as a writer of the option. CASH FLOW RISK. The Fund expects that a substantial portion of the cash flow it receives will be derived from its investments in equity securities of MLP entities. The amount and tax characterization of cash available for distribution by an MLP entity depends upon the amount of cash generated by such entity's operations. Cash available for distribution by MLP entities will vary widely from quarter to quarter and is affected by various factors affecting the entity's operations. In addition to the risks described herein, operating costs, capital expenditures, acquisition costs, construction costs, exploration costs and borrowing costs may reduce the amount of cash that an MLP entity has available for distribution in a given period. SMALL CAPITALIZATION RISK. The Fund may invest in securities of MLP entities and other issuers that have comparatively smaller capitalizations relative to issuers whose securities are included in major benchmark indices, which present unique investment risks. LOWER GRADE SECURITIES RISK. The Fund may invest in fixed-income securities rated below investment grade, which are commonly referred to as "junk bonds." Investment in securities of below-investment grade quality involves substantial risk of loss. FOREIGN SECURITIES. Investing in securities of foreign companies (or foreign governments) may involve certain risks not typically associated with investing in domestic companies. The prices of foreign securities may be affected by factors not present with securities traded in the U.S. markets, including, political and economic conditions, less stringent regulation and higher volatility. NON-DIVERSIFIED STATUS. The Fund may invest a greater portion of its assets in a more limited number of issuers than a diversified fund. In addition to the risks described above, the Fund is also subject to: Affiliated Party Risk, Energy Sector Risks, Other Sector Risks, Restricted Securities Risks, Cash Flow Risk, Liquidity Risk, Valuation Risk, Interest Rate Risk, Portfolio Turnover Risk, Derivatives Risk, Market Discount Risk, Other Investment Companies Risk, Royalty Trust Risk, Financial Leverage, Management Risk, and Current Developments.

(f) Calculated by subtracting the Fund's total liabilities (not including the borrowings) from the Fund's total assets and dividing by the total borrowings. See notes to financial statements. SemiAnnual Report | May 31, 2008 | l7 FMO | Fiduciary/Claymore MLP Opportunity Fund Notes to FINANCIAL STATEMENTS | MAY 31, 2008 (UNAUDITED) Note 1 - ORGANIZATION: Fiduciary/Claymore MLP Opportunity Fund (the "Fund") was organized as a Delaware statutory trust on October 4, 2004. The Fund is registered as a non-diversified, closed-end management investment company under the Investment Company Act of 1940, as amended. The Fund's investment objective is to provide a high level of after-tax total return with an emphasis on current distributions paid to shareholders. The Fund has been structured to seek to provide an efficient vehicle through which its shareholders may invest in a portfolio of publicly traded securities of master limited partnerships ("MLPs") and MLP affiliates. MLPs combine the tax benefits of limited partnerships with the liquidity of publicly traded securities. The Fund believes that as a result of the tax characterization of cash distributions made by MLPs to their investors (such as the Fund) a significant portion of the Fund's income will be tax-deferred returns of capital, which will allow distributions by the Fund to its shareholders to include high levels of tax-deferred income. There can be no assurance that the Fund will achieve its investment objective. Note 2 - ACCOUNTING POLICIES: The preparation of the financial statements in accordance with U.S. generally accepted accounting principles 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 Fund. (a) VALUATION OF INVESTMENTS Readily marketable securities listed on an exchange are valued at the last reported sale price on the primary exchange or in the principal over the counter ("OTC") market on which they are traded. Readily marketable securities traded on an exchange or OTC for which there are no transactions on a given day are valued at the mean of the closing bid and asked prices. Securities traded on NASDAQ are valued at the NASDAQ Official Closing Price. Debt securities are valued by independent pricing services or dealers using the last available bid price for such securities or, if such prices are not available, at prices for securities of comparable maturity, quality and type. For those securities where quotations or prices are not available, including restricted securities, valuations are determined in accordance with procedures established in good faith by the Board of Trustees. These procedures consider factors such as discounts to publicly traded securities and/or securities with similar yields, quality, type of issue and duration. Interest rate swaps are valued at closing prices for such contracts established by the dealer. Short-term securities having a remaining maturity of sixty days or less are valued at amortized cost, which approximates market value. In September, 2006, the Financial Accounting Standards Board ("FASB") issued Statement of Financial Accounting Standards No. 157, "Fair Valuation Measurements" ("FAS 157"). This standard clarifies the definition of fair value for financial reporting, establishes a framework for measuring fair value and requires additional disclosures about the use of fair value measurements. FAS 157 establishes three different categories for valuations. Level 1 valuations are those based upon quoted prices in active markets. Level 2 valuations are those based upon quoted prices in inactive markets or based upon significant observable inputs (i.e. yield curves; benchmark interest rates; indices). Level 3 valuations are those based upon unobservable inputs (i.e. discounted cash flow analysis; non-market based methods used to determine fair valuation). Details of the valuations as of May 31, 2008 were as follows: DESCRIPTION SECURITIES DERIVATIVES TOTAL ---------------------------------------------------------------- (value in $000s) Level 1 $ 602,491 $ - $ 602,491 Level 2 33,154 2,079 35,233 Level 3 20,655 - 20,655 ---------------------------------------------------------------- Total $ 656,300 $ 2,079 $ 658,379 ---------------------------------------------------------------- LEVEL 3 HOLDINGS SECURITIES DERIVATIVES TOTAL -------------------------------------------------------------------------------------- (value in $000s) Beginning Balance at 11/30/07 $ 20,418 $ - $ 20,418 Total Realized Gain/Loss - - - Change in Unrealized Gain/Loss 83 - 83 Net Purchases and Sales 154 - 154 Net Transfers In/Out - - - -------------------------------------------------------------------------------------- Ending Balance at 5/31/08 $ 20,655 $ - $ 20,655 ====================================================================================== (b) INVESTMENT TRANSACTIONS AND INVESTMENT INCOME Investment transactions are accounted for on the trade date. Realized gains and losses on investments are determined on the identified cost basis. Dividend income is recorded on the ex-dividend date and interest income is recorded on an accrual basis. Discounts or premiums on debt securities purchased are accreted or amortized to interest income over the lives of the respective securities using the effective interest method. The Fund records the character of dividends received from MLPs based on estimates made at the time such distributions are received. These estimates are based upon a historical review of information available from each MLP and other industry sources. The Fund's characterization of the estimates may subsequently be revised based on information received from MLPs after their tax reporting periods conclude. For the six months ended May 31, 2008, the Fund estimated approximately 8% of its distributions from MLPs as investment income and approximately 92% as return of capital, which is reflected in the Statement of Operations. Subsequent to November 30, 2007, the Fund reclassified the amount of investment income and return of capital it recognized based on the 2007 tax reporting information received from the individual MLPs. This reclassification amounted to an increase in pre-tax net investment income of approximately $1.1 million ($0.6 million net of deferred tax benefit) and a corresponding decrease in unrealized appreciation of investments of approximately $1.1 million ($0.6 million net of deferred tax expense). The reclassification is reflected in the period ended May 31, 2008. (c) SWAPS A swap is an agreement to exchange the return generated by one instrument for the return generated by another instrument. The Fund may enter into swap agreements to manage its exposure to interest rates and/or credit risk or to generate income. Interest rate swap agreements involve the exchange by the Fund with another party of their respective commitments to pay or receive interest. The swaps are valued daily at current market value and any unrealized gain or loss is included in the Statement of Assets and Liabilities. Gain or loss is realized on the l8 | SemiAnnual Report | May 31, 2008 FMO | Fiduciary/Claymore MLP Opportunity Fund | NOTES TO FINANCIAL STATEMENTS (unaudited) continued termination date of the swap and is equal to the difference between the Fund's basis in the swap and the proceeds of the closing transaction, including any fees. During the period that the swap agreement is open, the Fund may be subject to risk from the potential inability of the counterparty to meet the terms of the agreement. The swaps involve elements of both market and credit risk in excess of the amounts reflected on the Statement of Assets and Liabilities. Realized gain (loss) upon termination of swap contracts is recorded on the Statement of Operations. Fluctuations in the value of swap contracts are recorded as a component of net change in unrealized appreciation (depreciation) of swap contracts. Net periodic payments received by the Fund are included as part of realized gains (losses) and, in the case of accruals for periodic payments, are included as part of unrealized appreciation (depreciation) on the Statement of Operations. (d) DISTRIBUTIONS TO SHAREHOLDERS The Fund intends to make quarterly distributions to shareholders. Distributions to shareholders are recorded on the ex-dividend date. Distributions are determined in accordance with U.S. generally accepted accounting principles which may differ from their ultimate characterization for federal income tax purposes. The Fund anticipates that a significant portion of its distributions will be comprised of return of capital as a result of the tax character of cash distributions made by MLPs. The Fund is unable to make final determinations as to the tax character of the distributions to shareholders until after the end of the calendar year. Note 3 - INVESTMENT ADVISORY AGREEMENT, SUB-ADVISORY AGREEMENT AND OTHER AGREEMENTS: Pursuant to an Investment Advisory Agreement (the "Advisory Agreement") between the Fund and Claymore Advisors, LLC (the "Adviser"), the Adviser will furnish offices, necessary facilities and equipment, oversee the activities of Fiduciary Asset Management, LLC (the "Sub-Adviser"), provide personnel including certain officers required for its administrative management and pay the compensation of all officers and Trustees of the Fund who are its affiliates. As compensation for these services, the Fund will pay the Adviser an annual fee, payable monthly, in an amount equal to 1.00% of the Fund's average daily Managed Assets (net assets plus any assets attributable to financial leverage). Pursuant to a Sub-Advisory Agreement (the "Sub-Advisory Agreement") between the Fund, the Adviser and the Sub-Adviser, the Sub-Adviser under the supervision of the Fund's Board of Trustees and the Adviser, provides a continuous investment program for the Fund's portfolio; provides investment research and makes and executes recommendations for the purchase and sale of securities; and provides certain facilities and personnel, including certain officers required for its administrative management and pays the compensation of all officers and Trustees of the Fund who are its affiliates. As compensation for its services, the Adviser pays the Sub-Adviser a fee, payable monthly, in an annual amount equal to 0.50% of the Fund's average daily Managed Assets. Under a separate Fund Administration agreement, the Adviser provides Fund Administration services to the Fund. As compensation for services performed under the Administration Agreement, the Adviser receives an administration fee payable monthly at the annual rate set forth below as a percentage of the average daily managed assets of the Fund: MANAGED ASSETS RATE ================================================================ First $200,000,000 0.0275% Next $300,000,000 0.0200% Next $500,000,000 0.0150% Over $1,000,000,000 0.0100% ---------------------------------------------------------------- The Bank of New York Mellon ("BNY") acts as the Fund's custodian, accounting agent and transfer agent. As custodian, BNY is responsible for the custody of the Fund's assets. As accounting agent, BNY is responsible for maintaining the books and records of the Fund's securities and cash. As transfer agent, BNY is responsible for performing transfer agency services for the Fund. Note 4 - FEDERAL INCOME TAXES: The Fund will be treated as a regular corporation, or "C" corporation, for U.S. federal income tax purposes. Accordingly, the Fund generally will be subject to U.S. federal income tax on its taxable income at the graduated rates applicable to corporations (currently at a maximum rate of 35%). In addition, as a regular corporation, the Fund will be subject to various state income taxes by reason of its investments in MLPs. The Fund may be subject to a 20% alternative minimum tax to the extent that it exceeds the Fund's regular income tax liability. The amount to which the Fund is required to pay U.S. corporate income tax or alternative minimum tax could materially reduce the Fund's cash available to make distributions on Common Shares. Information on the tax components of investments as of May 31, 2008 is as follows: COST OF NET TAX NET TAX INVESTMENTS GROSS TAX GROSS TAX UNREALIZED UNREALIZED FOR TAX UNREALIZED UNREALIZED APPRECIATION APPRECIATION PURPOSES APPRECIATION DEPRECIATION ON INVESTMENTS ON DERIVATIVES ============================================================================ $413,830,954 $257,759,297 $(15,290,318) $242,468,979 $2,078,516 Deferred income taxes reflect the net tax effect of temporary differences between the carrying amount of assets and liabilities for financial reporting purposes and the amounts used for tax purposes. The Fund will accrue deferred income taxes for its future tax liability associated with that portion of MLP distributions considered to be a tax-deferred return of capital as well as capital appreciation of its investments. For purposes of estimating deferred tax liability for financial statement reporting and determining its net asset value, the Fund will be required to rely, to some extent, on information provided by MLPs in which it invests. Such information may not be received in a timely manner. Accordingly, the Fund will, from time to time, modify its estimates or assumptions regarding its deferred tax liability as new information becomes available. Upon the sale of an equity security in an MLP, the Fund generally will be liable for any previously deferred taxes. The Fund's income tax provision consists of the following: Current taxes $ 721,336 Deferred federal income taxes benefit (5,275,885) Deferred state income taxes benefit (930,185) -------------------------------------------------------------------------------- Total current and deferred tax expense (benefit) $(5,484,734) -------------------------------------------------------------------------------- Total income tax expense differs from the amount computed by applying the federal statutory income tax rate of 35% to net investment income and realized and unrealized gains before taxes as follows: RATE ================================================================================ Application of statutory income tax rate benefit $ 5,090,382 35.00% State income tax benefit 830,052 5.71% Foreign income tax expense (435,700) (3.00)% -------------------------------------------------------------------------------- Total tax benefit $ 5,484,734 37.71% -------------------------------------------------------------------------------- SemiAnnual Report | May 31, 2008 | l9 FMO | Fiduciary/Claymore MLP Opportunity Fund | NOTES TO FINANCIAL STATEMENTS (unaudited) continued Components of the Fund's deferred tax liability as of May 31, 2008 are as follows: DEFERRED TAX ASSETS: Net operating loss carryforward $ 14,395,182 Valuation allowance (2,731,979) ------------------------------------------------------------------------------ Deferred tax asset 11,663,203 ------------------------------------------------------------------------------ DEFERRED TAX LIABILITIES: Unrealized gain on investments $ 97,552,978 ------------------------------------------------------------------------------ Gross deferred tax liability 97,552,978 ------------------------------------------------------------------------------ Net deferred tax liability $ 85,889,775 ------------------------------------------------------------------------------ At May 31, 2008, November 30, 2007 and November 30, 2006, the Fund recorded a valuation allowance against its deferred tax assets in the amount of $391,215, $1,665,241 and $675,523, respectively. This allowance occurred because it is unlikely that the Fund will be able to use net operating losses sourced to states (other than Illinois) because it is not projected that the Fund will have future taxable income sourced to these states. At November 30, 2007 and 2006, the Fund had a net operating loss for federal income tax purposes of $10,333,986 and $16,422,389, respectively. This net operating loss may be carried forward for 20 years, and would expire November 30, 2027 and 2026, respectively. On July 13, 2006, the 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 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. Management has evaluated the implications of FIN 48 and has determined it does not have any impact on the financial statements as of May 31, 2008. Tax years for 2005, 2006 and 2007 are still subject to examination by major jurisdictions. Note 5 - AFFILIATED COMPANIES: During the period, the Fund owned shares of the following affiliated companies. Affiliated companies are defined by the 1940 Act, as amended, as those companies in which a Fund holds 5% or more of the outstanding voting securities.

Note 7 - BORROWINGS: On July 15, 2005, the Fund entered into a commercial paper conduit funding agreement with a line of credit of $150,000,000. The Fund incurred an issuance cost of $500,000 associated with the $150,000,000 commercial paper conduit. This cost is being amortized to expense over a period of five years. A $25,000,000 addition to the line of credit was secured by the Fund and issued on May 24, 2007. Interest on the amount borrowed is based on the prevailing commercial paper rate plus 0.35%. An unused commitment fee of 0.15% is charged on the difference between the credit line of $175,000,000 and the amount borrowed. The commercial paper rate is reset periodically. At May 31, 2008 there was $175,000,000 outstanding in connection with the Fund's commercial paper conduit. The average daily amount of borrowings during the six months ended May 31, 2008 was $175,000,000 with a related weighted average interest rate of 4.16%, inclusive of the 0.35% program fee. The maximum amount outstanding during the six months ended May 31, 2008, was $175,000,000. Note 8 - CAPITAL: COMMON SHARES The Fund has an unlimited amount of common shares, $0.01 par value, authorized and 18,187,651 issued and outstanding. Transactions in common shares were as follows: SIX MONTHS ENDED YEAR ENDED MAY 31, 2008 NOVEMBER 30, 2007 ==================================================================================== Beginning shares 18,105,218 18,067,021 Shares issued through dividend reinvestment 82,433 38,197 ------------------------------------------------------------------------------------ Ending shares 18,187,651 18,105,218 ------------------------------------------------------------------------------------ Note 9 - CONCENTRATION OF RISK: Because the Fund is focused in MLP entities in the energy, natural resources and real estate sectors of the economy, such concentration may present more risks than if the Fund were broadly diversified over numerous industries and sectors of the economy. A downturn in the energy, natural resources or real estate sectors of the economy could have a larger impact on the Fund than on an investment company that does not concentrate in such sectors. At times, the performance of securities of companies in the energy, natural resources and real estate sectors of the economy may lag the performance of other sectors or the broader market as a whole. 20 | SemiAnnual Report | May 31, 2008 FMO | Fiduciary/Claymore MLP Opportunity Fund | NOTES TO FINANCIAL STATEMENTS (unaudited) continued An investment in MLP units involves risks that differ from a similar investment in equity securities, such as common stock, of a corporation. Holders of MLP units have the rights typically afforded to limited partners in a limited partnership. As compared to common shareholders of a corporation, holders of MLP units have more limited control and limited rights to vote on matters affecting the partnership. There are certain tax risks associated with an investment in MLP units. Additionally, conflicts of interest may exist between common unit holders, subordinated unit holders and the general partner of an MLP; for example a conflict may arise as a result of incentive distribution payments. Note 10 - RESTRICTED SECURITIES: The Fund may invest up to 40% of its Managed Assets in unregistered or otherwise restricted securities. Restricted securities are securities that are unregistered, held by control persons of the issuer or are subject to contractual restrictions on resale. The Fund will typically acquire restricted securities in directly negotiated transactions. Restricted securities are fair valued in accordance with procedures established by the Fund's Board of Trustees. As of May 31, 2008, the Fund held the following restricted securities: FAIR VALUE PER SHARE AT DATE OF CURRENT MARKET ACQUISITION DATE 5/31/08 SECURITY ACQUISITION SHARES COST VALUE (UNRESTRICTED)*** PRICE =============================================================================================================================== Abraxas Energy Partners, L.P. 5/25/07 525,211 $8,066,191 $ 8,750,015 $ 16.66 $ 16.66 Abraxas Petroleum Corp.* 5/25/07 114,230 - $ 295,033 - $ 2.58 BreitBurn Energy Partners L.P. 11/01/07 778,888 $20,640,532 $16,606,054 $ 27.00 $ 21.32 Clearwater GP Holding Co. 2/29/08 123 $ 187,828 $ 154,000 $ 1,252.03 $ 1,252.03 Clearwater Natural Resources L.P.** 8/01/05 43 - - - - Clearwater Natural Resources L.P. 8/01/05 892,857 $17,857,143 $ 8,928,570 - $ 10.00 Clearwater Natural Resources L.P. 10/02/06 252,764 $ 5,055,280 $ 2,527,640 - $ 10.00 Copano Energy, L.L.C., Unregistered Series D Units 3/14/08 190,000 $ 4,987,500 $ 5,669,794 $ 34.05 $ 29.84 Crosstex Energy, L.P., Senior Subordinated Series D Units 3/23/07 387,534 $10,050,005 $10,877,746 $ 34.65 $ 28.07 ------------------------- Total $66,844,479 $53,808,852 ========================= * Warrants. ** Incentive Distribution Rights. *** Valuation of unrestricted common stock on the acquisition date of the restricted securities. Note 11 - ACCOUNTING PRONOUNCEMENTS: In March 2008, the FASB issued SFAS No. 161, "Disclosures about Derivative Instruments and Hedging Activities." This standard is intended to enhance financial statement disclosures for derivative instruments and hedging activities and enable investors to understand: a) how and why a fund uses derivative instruments, b) how derivatives instruments and related hedge fund items are accounted for, and c) how derivative instruments and related hedge items affect a fund's financial position, results of operations and cash flows. SFAS No. 161 is effective for financial statements issued for fiscal years and interim periods beginning after November 15, 2008. As of May 31, 2008, management does not believe the adoption of SFAS No. 161 will impact the financial statement amounts; however, additional footnote disclosures may be required about the use of derivative instruments and hedging items. Note 12 - INDEMNIFICATIONS: In the normal course of business, the Fund enters into contracts that contain a variety of representations, which provide general indemnifications. The Fund's maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Fund that have not yet occurred. However, the Fund expects the risk of loss to be remote. Note 13 - SUBSEQUENT EVENT: Subsequent to May 31, 2008, the Fund declared a quarterly dividend of $0.37 per share. This dividend is payable on July 31, 2008 to shareholders of record on July 15, 2008. Subsequent to May 31, 2008, management received notice from the Fund's line of credit provider of their intent to not renew the Fund's line of credit. Management is evaluating alternative sources of leverage to replace the existing facility. It is anticipated, however, that the Fund's cost of leverage under any new facility will increase.

SemiAnnual Report | May 31, 2008 | 23 FMO | Fiduciary/Claymore MLP Opportunity Fund Dividend Reinvestment PLAN | (unaudited) Unless the registered owner of common shares elects to receive cash by contacting the Plan Administrator, all dividends declared on common shares of the Fund will be automatically reinvested by The Bank of New York Mellon (the "Plan Administrator"), Administrator for shareholders in the Fund's Dividend Reinvestment Plan (the "Plan"), in additional common shares of the Fund. Participation in the Plan is completely voluntary and may be terminated or resumed at any time without penalty by notice if received and processed by the Plan Administrator prior to the dividend record date; otherwise such termination or resumption will be effective with respect to any subsequently declared dividend or other distribution. Some brokers may automatically elect to receive cash on your behalf and may re-invest that cash in additional common shares of the Fund for you. If you wish for all dividends declared on your common shares of the Fund to be automatically reinvested pursuant to the Plan, please contact your broker. The Plan Administrator will open an account for each common shareholder under the Plan in the same name in which such common shareholder's common shares are registered. Whenever the Fund declares a dividend or other distribution (together, a "Dividend") payable in cash, non-participants in the Plan will receive cash and participants in the Plan will receive the equivalent in common shares. The common shares will be acquired by the Plan Administrator for the participants' accounts, depending upon the circumstances described below, either (i) through receipt of additional unissued but authorized common shares from the Fund ("Newly Issued Common Shares") or (ii) by purchase of outstanding common shares on the open market ("Open-Market Purchases") on the New York Stock Exchange or elsewhere. If, on the payment date for any Dividend, the closing market price plus estimated brokerage commission per common share is equal to or greater than the net asset value per common share, the Plan Administrator will invest the Dividend amount in Newly Issued Common Shares on behalf of the participants. The number of Newly Issued Common Shares to be credited to each participant's account will be determined by dividing the dollar amount of the Dividend by the net asset value per common share on the payment date; provided that, if the net asset value is less than or equal to 95% of the closing market value on the payment date, the dollar amount of the Dividend will be divided by 95% of the closing market price per common share on the payment date. If, on the payment date for any Dividend, the net asset value per common share is greater than the closing market value plus estimated brokerage commission, the Plan Administrator will invest the Dividend amount in common shares acquired on behalf of the participants in Open-Market Purchases. If, before the Plan Administrator has completed its Open-Market Purchases, the market price per common share exceeds the net asset value per common share, the average per common share purchase price paid by the Plan Administrator may exceed the net asset value of the common shares, resulting in the acquisition of fewer common shares than if the Dividend had been paid in Newly Issued Common Shares on the Dividend payment date. Because of the foregoing difficulty with respect to Open-Market Purchases, the Plan provides that if the Plan Administrator is unable to invest the full Dividend amount in Open-Market Purchases during the purchase period or if the market discount shifts to a market premium during the purchase period, the Plan Administrator may cease making Open-Market Purchases and may invest the uninvested portion of the Dividend amount in Newly Issued Common Shares at net asset value per common share at the close of business on the Last Purchase Date provided that, if the net asset value is less than or equal to 95% of the then current market price per common share; the dollar amount of the Dividend will be divided by 95% of the market price on the payment date. The Plan Administrator maintains all shareholders' accounts in the Plan and furnishes written confirmation of all transactions in the accounts, including information needed by shareholders for tax records. Common shares in the account of each Plan participant will be held by the Plan Administrator on behalf of the Plan participant, and each shareholder proxy will include those shares purchased or received pursuant to the Plan. The Plan Administrator will forward all proxy solicitation materials to participants and vote proxies for shares held under the Plan in accordance with the instruction of the participants. There will be no brokerage charges with respect to common shares issued directly by the Fund. However, each participant will pay a pro rata share of brokerage commission incurred in connection with Open-Market Purchases. The automatic reinvestment of Dividends will not relieve participants of any Federal, state or local income tax that may be payable (or required to be withheld) on such Dividends. The Fund reserves the right to amend or terminate the Plan. There is no direct service charge to participants with regard to purchases in the Plan; however, the Fund reserves the right to amend the Plan to include a service charge payable by the participants. All correspondence or questions concerning the Plan should be directed to the Plan Administrator, The Bank of New York Mellon, Attention: Stock Transfer Department, 101 Barclay 11E, New York, NY 10286, Phone Number: (866) 488-3559. 24 | SemiAnnual Report | May 31, 2008 FMO | Fiduciary/Claymore MLP Opportunity Fund Fund INFORMATION | BOARD OF TRUSTEES Randall C.

SemiAnnual Report | May 31, 2008 | 25 FMO | Fiduciary/Claymore MLP Opportunity Fund About the FUND MANAGER | FIDUCIARY ASSET MANAGEMENT, LLC Fiduciary is a registered investment adviser that manages a broad array of equity and fixed-income portfolios primarily for institutional investors and is based in St. Louis, Missouri. Fiduciary currently supervises and manages approximately $17.8 billion in assets for endowments & foundations, public pension plans, corporate trusts, union plans, Taft-Hartley plans, three exchange-listed closed-end funds and five private investment funds. INVESTMENT PHILOSOPHY Fiduciary believes that investment decisions should always be guided by a disciplined, risk-aware strategy that seeks to add value in all market environments. Their unique investment philosophy is multifaceted, utilizing macroeconomic analysis, disciplined security selection, cost-controlled trading procedures, continuous risk analysis and an unwavering focus on achieving shareholder objectives. INVESTMENT PROCESS The manager seeks to achieve the Fund's investment objective by investing primarily in securities of MLP (Master Limited Partnership) entities that Fiduciary believes offer attractive distribution rates and capital appreciation potential. Energy and natural resources represent a substantial portion of the MLP entities. In seeking investments, Fiduciary looks for MLPs that offer a combination of quality, growth and yield; intended to produce superior total returns over the long run. In selecting individual positions, the manager employs Fiduciary's top-down process which considers a combination of quantitative, qualitative and relative value factors. Fiduciary emphasizes rigorous proprietary analysis and valuation models constructed and maintained by its in-house investment analysts, while maintaining active dialogues with research analysts covering the MLP entities and an ongoing relationship with company management. In applying its selection criteria, the manager considers a company's proven track record, business prospects, strong record of distribution or dividend growth, ratios of debt to cash flow, coverage ratios with respect to distributions to unit holders, distribution incentive structure and the composition and goals of the company management team. 26 | SemiAnnual Report | May 31, 2008 (This page is intentionally left blank) FIDUCIARY ASSET MANAGEMENT, LLC 8112 Maryland Ave. Suite 400 St. Louis, MO 63105 CLAYMORE SECURITIES, INC. 2455 Corporate West Drive Lisle, IL 60532 Member FINRA/SIPC (07/08) FMO LISTED NYSE FMO-SAR-0508 Item 2.
