See notes to financial statements. l0 | SemiAnnual Report | April 30, 2008 AGC | Advent/Claymore Global Convertible Securities & Income Fund Notes to FINANCIAL STATEMENTS | APRIL 30, 2008 (unaudited) Note 1 - ORGANIZATION: Advent/Claymore Global Convertible Securities & Income Fund (the "Fund") was organized as a Delaware statutory trust on February 26, 2007. The Fund is registered as a diversified, closed-end management investment company under the Investment Company Act of 1940, as amended. The Fund's primary investment objective is to provide total return, through a combination of capital appreciation and current income. The Fund will pursue its investment objective by investing 80% of its assets in a diversified portfolio of convertible securities and non-convertible income-producing securities, each of U.S. and non-U.S. issuers. 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 Equity securities listed on an exchange are valued at the last reported sale price on the primary exchange on which they are traded. Equity securities traded on an exchange 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. Equity securities not listed on a securities exchange or NASDAQ are valued at the mean of the closing bid and asked prices. Debt securities are valued by independent pricing services or dealers using the mean of the closing bid and asked prices for such securities or, if such prices are not available, at prices for securities of comparable maturity, quality and type. Futures contracts are valued using the settlement price established each day on the exchange on which they are traded. Exchange-traded options are valued at the closing price, if traded that day. If not traded, they are valued at the mean of the bid and asked prices on the primary exchange on which they are traded. For those securities where quotations or prices are not available, valuations are determined in accordance with procedures established in good faith by the Board of Trustees. Short-term securities with remaining maturities of 60 days or less are valued at amortized cost, which approximates market value. The Fund values synthetic convertible securities based on quotations obtained from unaffiliated brokers who are the principal market-makers in such securities. Such valuations are derived by the brokers from proprietary models which are generally based on readily available market information including valuations of the common stock underlying the synthetic security, and the volatility observed in the market on such common stocks. Because of the inherent uncertainty in the valuation process, it is reasonably possible that the estimated values may differ from the values that would have been used had a more active market for the investments existed, and such differences could be material. As of April 30, 2008, approximately $238,740,783, representing 34.7% of total fund investments, are invested in these synthetic convertible securities. (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. (C) CURRENCY TRANSLATION Assets and liabilities denominated in foreign currencies are translated into U.S. dollars at the mean of the bid and asked price of respective exchange rates on the last day of the period. Purchases and sales of investments denominated in foreign currencies are translated at the exchange rate on the date of the transaction. The Fund does not isolate that portion of the results of operations resulting from changes in foreign exchange rates on investments from the fluctuations arising from changes in market prices of securities held. Such fluctuations are included with the net realized and unrealized gain or loss from investments. Foreign exchange realized gain or loss resulting from holding of a foreign currency, expiration of a currency exchange contract, difference in exchange rates between the trade date and settlement date of an investment purchased or sold, and the difference between dividends or interest actually received compared to the amount shown in the Fund's accounting records on the date of receipt is shown as net realized gains or losses on foreign currency transactions in the Fund's Statement of Operations. Foreign exchange unrealized gain or loss on assets and liabilities, other than investments, is shown as unrealized appreciation (depreciation) on foreign currency translation in the Fund's Statement of Operations. (D) COVERED CALL OPTIONS The Fund will pursue its primary objective by employing an option strategy of writing (selling) covered call options on up to 25% of the securities held in the portfolio of the Fund. The Fund seeks to generate current gains from option premiums as a means to enhance distributions payable to shareholders. An option on a security is a contract that gives the holder of the option, in return for a premium, the right to buy from (in the case of a call) or sell to (in the case of a put) the writer of the option the security underlying the option at a specified exercise or "strike" price. The writer of an option on a security has the obligation upon SemiAnnual Report | April 30, 2008 | 11 AGC | Advent/Claymore Global Convertible Securities & Income Fund | NOTES TO FINANCIAL STATEMENTS (unaudited) continued exercise of the option to deliver the underlying security upon payment of the exercise price (in the case of a call) or to pay the exercise price upon delivery of the underlying security (in the case of a put). There are several risks associated with transactions in options on securities. 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 writer of the option. Once an option writer has received an exercise notice, it cannot effect a closing purchase transaction in order to terminate its obligation under the option and must deliver the underlying security at the exercise price. When an option is written, the premium received is recorded as an asset with an equal liability and is subsequently marked to market to reflect the current market value of the option written. These liabilities are reflected as options written in the Statement of Assets and Liabilities. Premiums received from writing options which expire unexercised are recorded on the expiration date as a realized gain. The difference between the premium received and the amount paid on effecting a closing purchase transaction, including brokerage commissions, is also treated as a realized gain, or if the premium is less than the amount paid for the closing purchase transactions, as a realized loss. If a call option is exercised; the premium is added to the proceeds from the sale of the underlying security in determining whether there has been a realized gain or loss. (E) FORWARD EXCHANGE CURRENCY CONTRACTS The Fund may enter into forward exchange currency contracts in order to hedge its exposure to change in foreign currency exchange rates on its foreign portfolio holdings, to hedge certain firm purchases and sales commitments denominated in foreign currencies and for investment purposes. A forward exchange currency contract is a commitment to purchase or sell a foreign currency on a future date at a negotiated forward rate. The gain or loss arising from the difference between the original contracts and the closing of such contracts would be included in net realized gain or loss on foreign currency transactions. Fluctuations in the value of open forward exchange currency contracts are recorded for financial reporting purposes as unrealized appreciation and depreciation by the Fund. Risk may arise from the potential inability of a counterparty to meet the terms of a contract and from unanticipated movements in the value of a foreign currency relative to the U.S. dollar. The face or contract amount, in U.S. dollars, reflects the total exposure the Fund has in that particular currency contract. Forward exchange currency contracts involve elements of both market and credit risk in excess of the amounts reflected on the Statement of Assets and Liabilities. (F) 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 as well as to attempt to enhance return. Total return swap agreements are contracts in which one party agrees to make payments of the total return from the underlying asset during a specified period in return for receiving payments equal to a fixed or floating rate of interest or the total return from another designated underlying asset. 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 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. (G) DISTRIBUTIONS TO SHAREHOLDERS The Fund declares and pays monthly dividends to common shareholders. These dividends consist of investment company taxable income, which generally includes qualified dividend income, ordinary income and short-term capital gains. Any net realized long-term gains are distributed annually to common shareholders. Distributions to shareholders are recorded on the ex-dividend date. The amount and timing of distributions are determined in accordance with federal income tax regulations, which may differ from U.S. generally accepted accounting principles. l2 | SemiAnnual Report | April 30, 2008 AGC | Advent/Claymore Global Convertible Securities & Income Fund | NOTES TO FINANCIAL STATEMENTS (unaudited) continued Note 3 - INVESTMENT MANAGEMENT AND ADVISORY AGREEMENTS AND OTHER AGREEMENTS: Pursuant to an Investment Advisory Agreement (the "Agreement") between Claymore Advisors, LLC (the "Adviser") and the Fund, the Adviser furnishes offices, necessary facilities and equipment, provides administrative services to the Fund, oversees the activities of Advent Capital Management, LLC (the "Investment Manager"), provides personnel and pays the compensation of all Trustees and Officers of the Fund who are its affiliates. As compensation for these services, the Fund pays the Adviser an annual fee, payable monthly in arrears, at an annual rate equal to 0.40% of the average Managed Assets during such month. Managed Assets means the total of assets of the Fund (including any assets attributable to any preferred shares or otherwise attributable to the use of financial leverage, if any) less the sum of accrued liabilities. Pursuant to an Investment Management Agreement between the Investment Manager and the Fund, the Fund has agreed to pay the Investment Manager an annual fee, payable monthly in arrears, at an annual rate equal to 0.60% of the average Managed Assets during such month for the services and facilities provided by the Investment Manager to the Fund. These services include the day-to-day management of the Fund's portfolio of securities, which includes buying and selling securities for the Fund and investment research. The Investment Manager also provides personnel to the Fund and pays the compensation of all Trustees and Officers of the Fund who are its affiliates. The Bank of New York Mellon ("BNY") acts as the Fund's custodian, administrator and transfer agent. As custodian, BNY is responsible for the custody of the Fund's assets. As administrator, 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. Certain Officers and Trustees of the Fund are also Officers and Directors of the Adviser or Investment Manager. The Fund does not compensate its Officers or Trustees who are Officers of the aforementioned firms. Note 4 - FEDERAL INCOME TAXES: The Fund intends to comply with the requirements of Subchapter M of the Internal Revenue Code of 1986, as amended, applicable to regulated investment companies. Accordingly, no provision for U.S. federal income taxes is required. In addition, by distributing substantially all of its ordinary income and long-term capital gains, if any, during each calendar year, the Fund intends not to be subject to U.S. federal excise tax. At April 30, 2008 the cost and related gross unrealized appreciation and depreciation on investments for tax purposes, excluding written options and foreign currency translations are as follows: NET TAX UNREALIZED NET TAX UNREALIZED COST OF GROSS TAX GROSS TAX APPRECIATION DEPRECIATION ON INVESTMENTS UNREALIZED UNREALIZED (DEPRECIATION) DERIVATIVES AND FOR TAX PURPOSES APPRECIATION DEPRECIATION ON INVESTMENTS FOREIGN CURRENCY --------------------------------------------------------------------------------------------------- $733,514,481 $20,357,105 $(66,673,222) $(46,316,117) $(15,148,891) The differences between book basis and tax basis unrealized appreciation/(depreciation) is attributable to the tax deferral of losses on wash sales, straddles and additional income accrued for tax purposes on certain convertible securities. For the period ended October 31, 2007 the tax character of distributions paid, as reflected in the Statement of Changes in Net Assets of $15,215,695 was ordinary income. The final determination of the source of the 2008 distributions for tax purposes will be made after the end of the Fund's fiscal year and will be reported to shareholders in January 2009 on Form 1099-DIV. On July 13, 2006, the Financial Accounting Standards Board ("FASB") released FASB Interpretation No. 48, "Accounting for Uncertainty in Income Taxes" ("FIN 48"). FIN 48 provides guidance for how uncertain tax positions should be recognized, measured, presented and disclosed in the financial statements. FIN 48 requires the evaluation of tax positions taken or expected to be taken in the course of preparing the Fund's tax returns to 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 implication of FIN 48 and has determined it does not have any impact on the financial statements as of April 30, 2008.

The Fund has an unlimited amount of common shares, $0.001 par value, authorized and 31,867,616 issued and outstanding. Of this amount, the Fund issued 28,750,000 shares of common stock in its initial public offering. On June 11, 2007, June 18, 2007 and July 11, 2007, the Fund issued an additional 1,750,000 shares, 750,000 shares and 555,900 shares, respectively, pursuant to an over allotment option. These shares were issued at $19.10 per share after deducting the sales load but before underwriters' expense reimbursement. Offering costs, estimated at $1,272,236 or $0.04 per share, in connection with the issuance of common shares have been borne by the Fund and were charged to paid-in capital. The Adviser and Investment Manager have agreed to pay offering expenses (other than sales load, but including reimbursement of expenses to the underwriters) in excess of $0.04 per common share. PREFERRED SHARES On June 12, 2007, the Fund's Board of Trustees authorized the issuance of Auction Market Preferred Shares ("AMPS"), as part of the Fund's leverage strategy. AMPS issued by the Fund have seniority over the common shares. On September 14, 2007, the Fund issued 3,400 shares of AMPS Series T7 and 3,400 shares of AMPS Series W7, each with a liquidation value of $25,000 per share plus accrued dividends. Offering costs, including the 1% sales charge associated with the issuance of AMPS, estimated at $2,100,000 were borne by the common shareholders as a direct reduction to paid-in-capital. SemiAnnual Report | April 30, 2008 | 15 AGC | Advent/Claymore Global Convertible Securities & Income Fund | NOTES TO FINANCIAL STATEMENTS (unaudited) continued Dividends are accumulated daily at a rate set through an auction process. Beginning February 13, 2008, the auction process resulted in a failed auction. Provisions in the offering documents of the Fund's AMPS provide a mechanism to set a maximum rate in the event of a failed auction, and thus, investors in the Fund's AMPS will continue to be entitled to receive payment for holding these AMPS. This maximum rate is determined based upon a multiple of or a spread to LIBOR, whichever is greater. Distributions of net realized capital gains, if any, are made annually. For the period ended April 30, 2008, the annualized dividend rates ranged from: HIGH LOW AT APRIL 30, 2008 ----------------------------------------------------------------------- Series T7 6.00% 3.88% 3.96% Series W7 6.00% 3.94% 4.08% The Fund is subject to certain limitations and restrictions while Preferred Shares are outstanding. Failure to comply with these limitations and restrictions could preclude the Fund from declaring any dividends or distributions to common shareholders or repurchasing common shares and/or could trigger the mandatory redemption on Preferred Shares at their liquidation value. Preferred Shares, which are entitled to one vote per share, generally vote with the common stock but vote separately as a class to elect two Trustees and on any matters affecting the rights of the Preferred Shares. Note 8 - 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 9 - SUBSEQUENT EVENT: Subsequent to April 30, 2008, the Fund declared on May 1, 2008 and June 2, 2008, monthly dividends to common shareholders of $0.1458 per common share. These dividends are payable on May 30, 2008 and June 30, 2008 to shareholders of record on May 15, 2008 and June 13, 2008 respectively. On March 11, 2008, the Board of Trustees approved Claymore Advisors, LLC to replace BNY as the Fund Administration Agent effective May 1, 2008. Note 10 - ACCOUNTING PRONOUNCEMENTS: In September 2006, the FASB released Statement of Financial Accounting Standards No. 157, "Fair Value 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 is effective for financial statements issued for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. As of April 30, 2008, the Fund does not believe the adoption of FAS 157 will impact the amounts reported in the financial statements, however, additional disclosure will be required about the inputs used to develop measurements of fair value and the effect of certain of the measurements reported in the Statement of Operations for a fiscal period. 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 April 30, 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. l6 | SemiAnnual Report | April 30, 2008 This Page Intentionally Left Blank.

SemiAnnual Report | April 30, 2008 | 19 AGC | Advent/Claymore Global Convertible Securities & Income 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. 20 | SemiAnnual Report | April 30, 2008 This Page Intentionally Left Blank.
