DEAR SHAREHOLDER

Tracy V. Maitland

President and Chief Executive Officer

We thank you for your investment in the Advent Claymore Convertible Securities and Income Fund (the “Fund”). This report covers the Fund’s performance for the six months ended April 30, 2015.

Advent Capital Management, LLC (“Advent” or the “Investment Adviser”) serves as the Fund’s Investment Adviser. Based in New York, New York, with additional investment personnel in London, England, Advent is a credit-oriented firm specializing in the management of global convertible, high-yield and equity securities across three lines of business—long-only strategies, hedge funds, and closed-end funds. As of April 30, 2015, Advent managed approximately $8.5 billion in assets.

Guggenheim Funds Distributors, LLC (the “Servicing Agent”) serves as the servicing agent to the Fund. The Servicing Agent is an affiliate of Guggenheim Partners, LLC, a global diversified financial services firm.

The Fund’s investment objective is to provide total return through a combination of capital appreciation and current income. Under normal market conditions, the Fund invests at least 80% of its managed assets in a diversified portfolio of convertible securities and non-convertible income securities. Under normal market conditions, the Fund will invest at least 30% of its managed assets in convertible securities and may invest up to 70% in non-convertible income securities. The Fund may invest without limitation in foreign securities. The Fund’s non-fundamental investment policies were changed during the period and took effect in January 2015. Please see the Questions & Answers section following for more information.

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 ended April 30, 2015, the Fund generated a total return based on market price of 2.43% and a total return of 2.84% based on NAV. As of April 30, 2015, the Fund’s market price of $17.18 represented a discount of 9.39% to NAV of $18.96.

Past performance is not a guarantee of future results. The Fund’s NAV performance data reflect fees and expenses of the Fund. The market price of the Fund’s shares fluctuates from time to time, and it may be higher or lower than the Fund’s NAV.

In each month of the period, the Fund paid a monthly distribution of $0.0939 per share. The most recent monthly distribution represents an annualized distribution rate of 6.56% based upon the last closing market price of $17.18 as of April 30, 2015. There is no guarantee of any future distributions or that the current returns and distribution rate will be maintained. Please see Note 2(m) on page 43 for more information on distributions for the period.

April 30, 2015

We encourage shareholders to consider the opportunity to reinvest their distributions from the Fund through the Dividend Reinvestment Plan (“DRIP”), which is described in detail on page 57 of this report. When shares trade at a discount to NAV, the DRIP takes advantage of the discount by reinvesting the monthly 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 DRIP reinvests participants’ dividends in newly-issued common shares at the greater of NAV per share or 95% of the market price per share. The DRIP provides a cost-effective means to accumulate additional shares and enjoy the benefits of compounding returns over time.

The Fund is managed by a team of experienced and seasoned professionals led by myself in my capacity as Chief Investment Officer (as well as President and Founder) of Advent Capital Management, LLC. We encourage you to read the following Questions & Answers section, which provides additional information regarding the factors that influenced the Fund’s performance.

We thank you for your investment in the Fund and we are honored that you have chosen the Advent Claymore Convertible Securities and Income Fund as part of your investment portfolio.

QUESTIONS & ANSWERS

April 30, 2015

Advent Claymore Convertible Securities and Income Fund (the “Fund”) is managed by a team of seasoned professionals at Advent Capital Management, LLC (“Advent” or the “Investment Adviser”), led by Tracy V. Maitland, Advent’s Founder, President, and Chief Investment Officer. In the following interview, the management team discusses the convertible-securities and high-yield markets and Fund performance for the six-month period ended April 30, 2015.

Please describe the Fund’s objective and management strategies.

The Fund’s investment objective is to provide total return through a combination of capital appreciation and current income. Under normal market conditions, the Fund invests at least 80% of its managed assets in a diversified portfolio of convertible securities and non-convertible income-producing securities. Under normal market conditions, the Fund must invest at least 30% of its managed assets in convertible securities and may invest up to 70% in non-convertible income securities. The Fund may invest without limitation in foreign securities. Prior to January 12, 2015, the Fund invested at least 80% of its managed assets in a diversified portfolio of convertible securities and non-convertible income-producing securities, including U.S. and non-U.S. issuers, with at least 60% of its managed assets in convertible securities and up to 40% of its managed assets in non-convertible income-producing securities.

The Fund also uses a strategy of writing (selling) covered call options on up to 25% of the securities held in the portfolio. The objective of this strategy is to generate current gains from option premiums to enhance distributions payable to the holders of common shares. In addition, the Fund may invest in other derivatives, such as put options, forward foreign currency exchange contracts, futures contracts, and swaps.

The Fund uses financial leverage to finance the purchase of additional securities. Although financial leverage may create an opportunity for increased return for shareholders, it also results in additional risks and can magnify the effect of any losses. There is no assurance that the strategy will be successful. If income and gains earned on securities purchased with the financial leverage proceeds are greater than the cost of the financial leverage, shareholders’ return will be greater than if financial leverage had not been used. Conversely, if the income or gains from the securities purchased with the proceeds of financial leverage are less than the cost of the financial leverage, shareholders’ return will be less than if financial leverage had not been used.

Discuss the recent changes to Advent’s non-fundamental investment policies.

Modifications to non-fundamental investment policies approved by the Board of Trustees of the Fund and Advent’s other closed-end funds took effect on January 12, 2015. These modifications were designed to expand the portfolio management flexibility of the Funds and may provide an opportunity to enhance shareholder value through the Investment Manager’s expanded investment capabilities and ability to manage risk.

QUESTIONS & ANSWERS continued

April 30, 2015

Advent’s institutional strategies, which invest in the same asset classes as the Fund, have provided superior performance relative to applicable benchmarks. Accordingly, Advent is reallocating the Fund’s portfolio over time to establish a core portfolio of convertible bonds that will be managed, subject to the Fund’s investment policies and restrictions, in a manner similar to that of Advent’s Balanced Convertible Strategy. Advent’s Balanced Convertible Strategy seeks a high total return by investing in a portfolio of U.S. dollar convertible securities that provide equity-like returns while seeking to limit downside risk.

This core portfolio will be supplemented by investments in high yield securities selected in a manner similar to that of Advent’s High Yield Strategy. Advent’s High Yield Strategy seeks income and total return by investing primarily in high yielding corporate credit using fundamental and relative value analysis to identify undervalued securities.

Advent now uses a separate portion of the Fund’s portfolio to increase or decrease relative overall exposure to convertible securities, high yield securities, and equities. This portion of the Fund’s portfolio will incorporate leverage and operate as an asset allocation tool reflecting Advent’s conservative management philosophy and its views on the relative value of these three asset classes under changing market conditions.

Please describe the economic and market environment over the last six months.

World securities markets generally advanced in the six months ended April 30, 2015, spurred by healthy monetary conditions in the U.S. and direct injections of quantitative easing or other monetary support in various foreign geographies. In the U.S., various equity indices returned roughly mid-single-digits in the period, led by the health care sector, merger and acquisitions activity, and reasonable strength in the overall U.S. economy. Later in the period, however, slowing corporate earnings growth from falling commodity prices, the strong dollar, and a weaker economy in the first quarter of 2015 led to small corrections in the mid- and small-cap markets. Risk-free Treasury rates fell, and prices rose, continuing a trend from earlier in 2014 as the U.S. Federal Reserve (Fed) kept pushing out the normalization of short-term monetary policy. However, high-yield bonds, a key asset class for the Fund, returned less as spreads widened on exposure to the oil & gas sector and lower liquidity from dealer participants from regulatory changes.

Convertible bond returns were satisfactory, compared to equity indices, as the asset class piggybacked off the higher returns from the highly represented sectors of health care and technology and lower risk-free rates to come to returns that mimicked the equity indices. Exposure to foreign convertibles also helped as overseas securities benefitted from much higher equity returns and even more pronounced declines in bond yields and corporate bond spreads than the U.S. The announcement of a large asset purchase program by the European Central Bank (ECB) and expansion of the existing program by the Bank of Japan led to large advances in equity and bond markets there as well as large declines in the respective currencies. The Fund’s policy to hedge foreign currency exposure helped it to take advantage of asset price increases without suffering the related currency depreciation.

QUESTIONS & ANSWERS continued

April 30, 2015

How did the Fund perform in this environment?

How has the Fund’s leverage strategy affected performance?

As part of its investment strategy, the Fund utilizes leverage to finance the purchase of additional securities that provide increased income and potentially greater appreciation potential to common shareholders than could be achieved from a portfolio that is not leveraged.

The Fund’s leverage outstanding as of April 30, 2015, including borrowing and reverse repurchase agreements or the issuance of commercial paper or other forms of debt, was $262 million, approximately 37% of the Fund’s total managed assets.

There is no guarantee that the Fund’s leverage strategy will be successful, and the Fund’s use of leverage may cause the Fund’s NAV and market price of common shares to be more volatile.

The Fund’s use of leverage remained unchanged in absolute dollars as the fiscal half-year progressed. The Fund’s total return, defined as the return inclusive of reinvested dividends, was slightly higher than the cost of that leverage for the fiscal half-year. Therefore, on a simple comparison, the use of leverage had a modestly enhancing effect on shareholder returns for the period.

What was the impact of the Fund’s covered call strategy?

The Fund continues to seek income from occasionally overwriting equity positions and convertibles with call options. Equity allocations in the Fund declined in the six months ended April 30, 2015, as the Investment Manager sought out greater income and better relative value in the high-yield market. That plus a continued low-volatility environment led to lower opportunities to generate call option income than previous years. The CBOE SPX Volatility Index (VIX) averaged 15.5 for the six month period, slightly higher than the 14.0 of the previous fiscal year, but both are quite low by historical averages, and the figure had dropped again to 12.5 as of this writing in mid-May. While there is a reasonable forecast of higher volatility as the Fed embarks on a rate hike strategy, neither the hikes nor higher volatility have occurred yet, and the Fund will remain in a monitoring state for better opportunities to write option contracts for income in the near future.

April 30, 2015

How did other market measures perform in this environment?

For the six-month period ended April 30, 2015, the return of the Bank of America Merrill Lynch All Convertibles Index was 3.91%.

The return of the Bank of America Merrill Lynch High Yield Master II Index was 1.51%.

The Fund’s mandate differs materially from each of the individual indices. The Fund also maintains leverage and incurs transaction costs, advisory fees and other expenses, while these indices do not.

Please discuss the Fund’s distributions.

How was the Fund’s portfolio allocated among asset classes during the six months ended April 30, 2015, and how did this influence performance?

At April 30, 2015, the Fund’s assets were invested approximately 64.3% in convertible bonds, convertible preferred securities, and mandatory convertibles; 30.8% in corporate bonds; 2.7% in equities; 1.8% in cash and cash equivalents; and 0.4% in senior floating rate interests. At the previous report at October 31, 2014, the Fund’s assets were invested 65.9% in convertible bonds, convertible preferred securities, and mandatory convertibles; 27.6% in corporate bonds; 2.6% in equities; 3.2% in cash and cash equivalents; and 0.7% in senior floating rate interests. The rise in allocation toward corporate bonds and stocks reflects better risk/reward opportunities presenting themselves in corporate bonds after a late 2014 sell-off and the increase in equity valuations forecast with the delay of monetary tightening by the Federal Reserve and the drop in risk-free rates during the period. The convertible market also richened somewhat during the fiscal half-year, which led the Fund to reduce allocations in favor of straight bonds and equities.

International investments were 14.2% of the Fund’s long-term investments at April 2015, up from 12.3% in October 2014. Lower valuations and numerous central banks providing quantitative easing or monetary policy support led the Fund to take advantage of appreciation potential, particularly for equity-sensitive securities. The effect of currency fluctuations has been hedged in recent times so shareholders receive the local currency return of the underlying security, an advantageous policy in recent periods where foreign currencies have depreciated against the U.S. dollar.

Which investment decisions had the greatest effect on the Fund’s performance?

Among the large winners for the Fund over the period were holdings related to Ctrip.com International Ltd., Kingsoft Corp. Ltd., Penn Virginia Corp., Alta Mesa Holdings LP, and Kindred Healthcare, Inc.

Although foreign issuers are a relatively small part of the Fund, the large moves in equity and bond markets in overseas markets during the period led to some outsized gains for certain holdings.

QUESTIONS & ANSWERS continued

April 30, 2015

Chinese issuers shined with travel booking leader Ctrip.com International Ltd. (1.6% of long-term investments at period end) and Kingsoft Corp. Ltd. (0.4% of long-term investments at period end), an Internet and mobile software application company, providing noticeable gains. Ctrip convertibles benefitted after a period of investment with stronger revenue guidance for the March quarter, and Kingsoft’s Cheetah Mobile subsidiary continued to grow at over triple-digit rates with rapid global user acquisition and advertising monetization metrics. Both convertibles benefitted from monetary easing at the short end of the curve from the People’s Bank of China helping equity valuations.

In high-yield, bonds of some oil issuers in the Fund reversed higher as declines in global production helped stabilize or even spur a rebound in oil commodity prices. Large previous losses in Penn Virginia Corp. (0.3% of long-term investments at period end), an independent oil and gas company, and Alta Mesa Holdings LP (0.4% of long-term investments at period end), a privately held company engaged in onshore oil and gas acquisition and production, dissipated, and in the case of Alta Mesa the Fund managed to add to the position at bargain prices and ride the recovery.

In the U.S., the Fund continued to benefit from a myriad of health care investments—one example was mandatory convertibles in nursing care center operator Kindred Healthcare, Inc. (0.6% of long-term investments at period end), which is benefitting from synergies from its takeover of competitor Gentiva Health that closed in February.

Among the leading detractors for the Fund over the last year were holdings related to Wynn Resorts Ltd., Chesapeake Energy Corp., and Micron Technology, Inc.

Equity held in casino operator Wynn Resorts Ltd. (0.2% of long-term investments at period end) performed poorly, as the company struggled with a region-wide decline in gaming from corruption crackdowns and a slowing economy in China.

Preferred stock in Chesapeake Energy Corp. (0.7% of long-term investments at period end) fell after the oil and natural gas producer reported poor production trends with an asset base made smaller by recent asset sales to bolster liquidity.

Convertibles in memory semiconductor maker Micron Technology, Inc. (1.1% of long-term investments at period end) declined as the company’s profits suffered with a weakening personal computer market and weak pricing in its secondary market of FLASH storage chips. In general, these were company-specific issues that affected other investments in the same sector to a much smaller degree.

Do you have any other comments about the markets and the Fund?

Markets seem to have taken an aware but thus far unbothered attitude toward the specter of the first Fed short-term monetary policy rate increases since 2004. While there is general consensus there will be some level of increases in the Fed funds rate in the second half of 2015, the Open Market Committee’s attitude toward near-term economic data as determining future moves has introduced much uncertainty and debate over the slope and timing of rate increases into 2016. Further increasing uncertainty has been the slowdown in the U.S. economy in the first half of 2015. Foreign bond markets are generally highly priced from the liquidity injections from various central banks but

QUESTIONS & ANSWERS continued

will have that continued support through 2015 or longer with the potential of economic recovery aiding the balance sheets and leverage levels of corporate issuers. Prices of some select commodities have begun to rebound, perhaps reflecting a stronger foreign growth outlook than in the previous months.

Index Definitions

Indices are unmanaged, do not use leverage, and do not experience fees, expenses or transaction costs, and it is not possible to invest directly in an index.

Bank of America Merrill Lynch All Convertibles Index is comprised of approximately 500 issues of convertible bonds and preferred stock of all qualities.

Bank of America Merrill Lynch High Yield Master II Index is a commonly used benchmark index for high yield corporate bonds. It is a measure of the broad high yield market.

VIX is the ticker symbol for the Chicago Board Options Exchange Market Volatility Index, a popular measure of the implied volatility of S&P 500 index options. It is a weighted blend of prices for a range of options on the S&P 500 index.

NOTES TO FINANCIAL STATEMENTS (Unaudited)

April 30, 2015

Note 1 – Organization:

Advent Claymore Convertible Securities and Income Fund (the “Fund”) was organized as a Delaware statutory trust on February 19, 2003. The Fund is registered as a diversified, closed-end management investment company under the Investment Company Act of 1940, as amended.

The Fund’s investment objective is to provide total return through a combination of capital appreciation and current income. The Fund pursues its investment objective by investing at least 80% of its assets in a diversified portfolio of convertible securities and non-convertible income producing securities.

Note 2 – Accounting Policies:

The preparation of the financial statements in accordance with U.S. generally accepted accounting principles (“GAAP”) 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 the 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 or on the over-the-counter market and for which there are no transactions on a given day are valued at the mean of the closing bid and ask 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 mean of the closing bid and ask prices for such securities or, if such prices are not available, at prices for securities of comparable maturity, quality and type. If sufficient market activity is limited or does not exist, the pricing providers or broker-dealers may utilize proprietary valuation models which consider market characteristics such as benchmark yield curves, option-adjusted spreads, credit spreads, estimated default rates, coupon rates, anticipated timing of principal repayments, underlying collateral, or other unique security features in order to estimate relevant cash flows, which are then discounted to calculate a security’s fair value. Exchange-traded funds and listed closed-end funds are valued at the last sale price or official closing price on the exchange where the security is principally 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 ask prices on the primary exchange on which they are traded. Futures contracts are valued using the settlement price established each day on the exchange on which they are traded. Swaps are valued daily by independent pricing services or dealers using the mid price. Forward foreign currency exchange contracts are valued daily at current exchange rates. The Fund values money market funds at net asset value. Short-term securities with remaining maturities of 60 days or less are valued at market price, or if a market price is not available, at amortized cost, provided such amount approximates market value.

For those securities where quotations or prices are not available, the valuations are determined in accordance with procedures established in good faith by management and approved by the Board of Trustees. A valuation committee consisting of representatives from investment management, fund administration, legal and compliance is responsible for the oversight of the valuation process of the Fund and convenes monthly, or more frequently as needed. The valuation committee reviews

NOTES TO FINANCIAL STATEMENTS (Unaudited) continued

April 30, 2015

monthly Level 3 fair valued securities methodology, price overrides, broker quoted securities, price source changes, illiquid securities, unchanged priced securities, halted securities, price challenges, fair valued securities sold and back testing trade prices in relation to prior day closing prices. On a quarterly basis, the valuations and methodologies of all Level 3 fair valued securities are presented to the Fund’s Board of Trustees.

Valuations in accordance with these procedures are intended to reflect each security’s (or asset’s) fair value. Such fair value is the amount that the Fund might reasonably expect to receive for the security (or asset) upon its current sale. Each such determination is based on a consideration of all relevant factors, which are likely to vary from one security to another. Examples of such factors may include, but are not limited to: (i) the type of security, (ii) the initial cost of the security, (iii) the existence of any contractual restrictions on the security’s disposition, (iv) the price and extent of public trading in similar securities of the issuer or of comparable companies, (v) quotations or evaluated prices from broker-dealers and/or pricing services, (vi) information obtained from the issuer, analysts, and/or the appropriate stock exchange (for exchange traded securities), (vii) an analysis of the company’s financial statements, and (viii) an evaluation of the forces that influence the issuer and the market(s) in which the security is purchased and sold (e.g. the existence of pending merger activity, public offerings or tender offers that might affect the value of the security). There were no securities fair valued in accordance with such procedures established by the Board of Trustees as of April 30, 2015.

GAAP requires disclosure of fair valuation measurements as of each measurement date. In compliance with GAAP, the Fund follows a fair value hierarchy that distinguishes between market data obtained from independent sources (observable inputs) and the Fund’s own market assumptions (unobservable inputs). These inputs are used in determining the value of the Fund’s investments and summarized in the following fair value hierarchy:

Level 1 – quoted prices in active markets for identical securities

Level 2 – quoted prices in inactive markets or other significant observable inputs (e.g. quoted prices for similar securities; interest rates; prepayment speed; credit risk; yield curves)

Level 3 – significant unobservable inputs (e.g. discounted cash flow analysis; non-market based methods used to determine fair value)

Observable inputs are those based upon market data obtained from independent sources, and unobservable inputs reflect the Fund’s own assumptions based on the best information available. A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input both individually and in aggregate that is significant to the fair value measurement. The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

The following are certain inputs and techniques that are generally utilized to evaluate how to classify each major type of investment in accordance with GAAP.

AVK l ADVENT CLAYMORE CONVERTIBLE SECURITIES AND INCOME FUND SEMIANNUAL REPORT l 37

NOTES TO FINANCIAL STATEMENTS (Unaudited) continued

April 30, 2015

Equity Securities (Common and Preferred Stock) – Equity securities traded in active markets where market quotations are readily available are categorized as Level 1. Equity securities traded in inactive markets and certain foreign equities are valued using inputs which include broker quotes, prices of securities closely related where the security held is not trading but the related security is trading, and evaluated price quotes received from independent pricing providers. To the extent that these inputs are observable, such securities are categorized as Level 2. To the extent that these inputs are unobservable, such securities are categorized as Level 3.

Convertible Bonds & Notes – Convertible bonds and notes are valued by independent pricing providers who employ matrix pricing models utilizing various inputs such as market prices, broker quotes, prices of securities with comparable maturities and qualities, and closing prices of corresponding underlying securities. To the extent that these inputs are observable, such securities are categorized as Level 2. To the extent that these inputs are unobservable, such securities are categorized as Level 3.

Corporate Bonds & Notes – Corporate bonds and notes are valued by independent pricing providers who employ matrix pricing models utilizing various inputs such as market prices, broker quotes, and prices of securities with comparable maturities and qualities, and closing prices of corresponding underlying securities. To the extent that these inputs are observable, such securities are categorized as Level 2. To the extent that these inputs are unobservable, such securities are categorized as Level 3.

Listed derivatives that are actively traded are valued based on quoted prices from the exchange and categorized in level 1 of the fair value hierarchy. Over-the-counter (OTC) derivative contracts including forward currency contracts and option contracts derive their value from underlying asset prices, indices, reference rates, and other inputs. Depending on the product and terms of the transaction, the fair value of the OTC derivative products can be modeled taking into account the counterparties’ creditworthiness and using a series of techniques, including simulation models. Many pricing models do not entail material subjectivity because the methodologies employed do not necessitate significant judgments, and the pricing inputs are observed from actively quoted markets. These OTC derivatives are categorized within level 2 of the fair value hierarchy.

The Fund did not hold any Level 3 securities during the six months ended April 30, 2015.

Transfers between valuation levels, if any, are in comparison to the valuation levels at the end of the previous fiscal year, and are effective using the fair value as of the end of the current fiscal period.

There were no transfers between valuation levels during the six months ended April 30, 2015.

If not referenced in the table, please refer to the Portfolio of Investments for a breakdown of investment type by industry category.

(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 net of applicable withholding taxes on the ex-dividend date and interest income is recorded on an accrual basis. Discounts on debt securities purchased are accreted to interest income over the lives of the respective securities using the effective interest method. Premiums on debt securities purchased are amortized to interest income up to the next call date of the respective securities using the effective interest method.

The Fund considers all demand deposits to be cash equivalents. Cash and cash equivalents are held at the Bank of New York Mellon.

(d) Due from Broker

Amounts due from broker, if any, may include cash due to the Fund as proceeds from investments sold, but not yet purchased as well as pending investment and financing transactions, which may be restricted until the termination of the financing transactions.

(e) Restricted Cash

A portion of cash on hand is pledged with a broker for current or potential holdings, which includes options, swaps, forward foreign currency exchange contracts and securities purchased on a when issued or delayed delivery basis.

As of April 30, 2015, there was no restricted cash outstanding.

AVK l ADVENT CLAYMORE CONVERTIBLE SECURITIES AND INCOME FUND SEMIANNUAL REPORT l 39

NOTES TO FINANCIAL STATEMENTS (Unaudited) continued

April 30, 2015

(f) Convertible Securities

The Fund invests in preferred stocks and fixed-income securities which are convertible into common stock. Convertible securities may be converted either at a stated price or rate within a specified period of time into a specified number of shares of common stock. Traditionally, convertible securities have paid dividends or interest greater than on the related common stocks, but less than fixed income non-convertible securities. By investing in a convertible security, the Fund may participate in any capital appreciation or depreciation of a company’s stock, but to a lesser degree than if it had invested in that company’s common stock. Convertible securities rank senior to common stock in a corporation’s capital structure and, therefore, entail less risk than the corporation’s common stock.

(g) Currency Translation

Assets and liabilities denominated in foreign currencies are translated into U.S. dollars at the mean of the bid and ask price of the respective exchange rates on the last day of the period. Purchases and sales of investments denominated in foreign currencies are translated at the mean of the bid and ask price of respective exchange rates 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 the holding of a foreign currency, expiration of a currency exchange contract, difference in the exchange rates between the trade date and settlement date of an investment purchased or sold, and the difference between dividends actually received compared to the amount shown in a Fund’s accounting records on the date of receipt are included as net realized gains or losses on foreign currency transactions in the Fund’s Statement of Operations.

Foreign exchange gain or loss on assets and liabilities, other than investments, are included in unrealized appreciation (depreciation) on foreign currency translation in the Fund’s Statement of Operations.

(h) Covered Call and Put Options

The Fund will pursue its objective by employing an option strategy of writing (selling) covered call options or put 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.

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, at value, 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.

NOTES TO FINANCIAL STATEMENTS (Unaudited) continued

April 30, 2015

(i) Forward Foreign Currency Exchange Contracts

The Fund entered into forward foreign currency exchange contracts in order to hedge its exposure to changes 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. Forward foreign currency exchange contracts are agreements between two parties to buy and sell currencies at a set price on a future date. Fluctuations in the value of open forward foreign currency exchange contracts are recorded for financial reporting purposes as unrealized appreciation and depreciation by the Fund until the contracts are closed. When the contracts are closed, realized gains and losses are recorded, and included on the Statement of Operations.

Forward foreign currency exchange involve elements of both market and credit risk in excess of the amounts reflected on the Statement of Assets and Liabilities.

(j) Senior Floating Rate Interests

Senior floating rate interests, or term loans, in which the Fund typically invests are not listed on a securities exchange or board of trade. Term loans are typically bought and sold by institutional investors in individually negotiated transactions. The term loan market generally has fewer trades and less liquidity than the secondary market for other types of securities. Due to the nature of the term loan market, the actual settlement date may not be certain at the time of purchase or sale. Interest income on term loans is not accrued until settlement date. Typically, term loans are valued by independent pricing services using broker quotes.

(k) Reverse Repurchase Agreements

In a reverse repurchase agreement, the Fund sells to a counterparty a security that it holds with a contemporaneous agreement to repurchase the same security at an agreed-upon price and date. Reverse repurchase agreements are valued based on the amount of cash received, which represents fair value. Reverse repurchase agreements are reflected as a liability on the Statement of Assets and Liabilities. Interest payments made are recorded as a component of interest expense on the Statement of Operations. The Fund monitors collateral market value for the reverse repurchase agreement, including accrued interest, throughout the life of the agreement, and when necessary, delivers or receives cash or securities in order to manage credit exposure and liquidity. If the counterparty defaults or enters insolvency proceeding, realization or return of the collateral to the Fund may be delayed or limited.

(l) Risks and Other Considerations

In the normal course of business, the Fund trades financial instruments and enters into financial transactions where risk of potential loss exists due to, among other things, changes in the market (market risk) or the potential inability of a counterparty to meet the terms of an agreement (counterparty risk). The Fund is also exposed to other risks such as, but not limited to, concentration, interest rate, credit and financial leverage risks.

Concentration of Risk. It is the Fund’s policy to invest a significant portion of its assets in convertible securities. Although convertible securities do derive part of their value from that of the securities into which they are convertible, they are not considered derivative financial instruments. However, certain of the Fund’s investments include features which render them more sensitive to price

AVK l ADVENT CLAYMORE CONVERTIBLE SECURITIES AND INCOME FUND SEMIANNUAL REPORT l 41

NOTES TO FINANCIAL STATEMENTS (Unaudited) continued

April 30, 2015

changes in their underlying securities. Consequently, this exposes the Fund to greater downside risk than traditional convertible securities, but still less than that of the underlying common stock.

Credit Risk. Credit risk is the risk that one or more income securities in the Fund’s portfolio will decline in price, or fail to pay interest and principal when due, because the issuer of the security experiences a decline in its financial status. The Fund’s investments in income securities involve credit risk. However, in general, lower rated, lower grade and non-investment grade securities carry a greater degree of risk that the issuer will lose its ability to make interest and principal payments, which could have a negative impact on the Fund’s net asset value or dividends.

Interest Rate Risk. Convertible and nonconvertible income-producing securities including preferred stock and debt securities (collectively, “income securities”) are subject to certain interest rate risks. If interest rates go up, the value of income securities in the Fund’s portfolio generally will decline. These risks may be greater in the current market environment because interest rates are near historically low levels. During periods of rising interest rates, the average life of certain types of income securities may be extended because of slower than expected principal payments. This may lock in a below market interest rate, increase the security’s duration (the estimated period until the security is paid in full) and reduce the value of the security. This is known as extension risk. During periods of declining interest rates, the issuer of a security may exercise its option to prepay principal earlier than scheduled, forcing the Fund to reinvest in lower yielding securities. This is known as call or prepayment risk. Lower grade securities have call features that allow the issuer to repurchase the security prior to its stated maturity. An issuer may redeem a lower grade security if the issuer can refinance the security at a lower cost due to declining interest rates or an improvement in the credit standing of the issuer.

Lower Grade Securities Risk. Investing in lower grade and non-investment grade securities involves additional risks. Securities of below investment grade quality are commonly referred to as “junk bonds” or “high yield securities.” Investment in securities of below investment grade quality involves substantial risk of loss. Securities of below investment grade quality are predominantly speculative with respect to the issuer’s capacity to pay interest and repay principal when due and therefore involve a greater risk of default or decline in market value due to adverse economic and issuer specific developments. Issuers of below investment grade securities are not perceived to be as strong financially as those with higher credit ratings. Issuers of lower grade securities may be highly leveraged and may not have available to them more traditional methods of financing. Therefore, the risks associated with acquiring the securities of such issuers generally are greater than is the case with higher rated securities. These issuers are more vulnerable to financial setbacks and recession than more creditworthy issuers, which may impair their ability to make interest and principal payments. The issuer’s ability to service its debt obligations also may be adversely affected by specific issuer developments, the issuer’s inability to meet specific projected business forecasts or the unavailability of additional financing. Therefore, there can be no assurance that in the future there will not exist a higher default rate relative to the rates currently existing in the market for lower grade securities. The risk of loss due to default by the issuer is significantly greater for the holders of lower grade securities because such securities may be unsecured and may be subordinate to other creditors of the issuer. Securities of below investment grade quality display increased price sensitivity to changing interest rates and to a deteriorating economic environment. The market values for securities of below investment grade quality tend to be more volatile and such securities

tend to be less liquid than investment grade debt securities. To the extent that a secondary market does exist for certain below investment grade securities, the market for them may be subject to irregular trading activity, wide bid/ask spreads and extended trade settlement periods.

Structured and Synthetic Convertible Securities Risk. The value of structured convertible securities can be affected by interest rate changes and credit risks of the issuer. Such securities may be structured in ways that limit their potential for capital appreciation and the entire value of the security may be at a risk of loss depending on the performance of the underlying equity security. Structured convertible securities may be less liquid than other convertible securities. The value of a synthetic convertible security will respond differently to market fluctuations than a convertible security because a synthetic convertible security is composed of two or more separate securities, each with its own market value. In addition, if the value of the underlying common stock or the level of the index involved in the convertible component falls below the exercise price of the warrant or option, the warrant or option may lose all value.

Foreign Securities and Emerging Markets Risk. Investing in non-U.S. issuers may involve unique risks, such as currency, political, economic and market risk. In addition, investing in emerging markets entails additional risk including, but not limited to: news and events unique to a country or region; smaller market size, resulting in lack of liquidity and price volatility; certain national policies which may restrict the Fund’s investment opportunities; less uniformity in accounting and reporting requirements; unreliable securities valuation; and custody risk.

Financial Leverage Risk. Certain risks are associated with the leveraging of common stock, including the risk that both the net asset value and the market value of shares of common stock may be subject to higher volatility and a decline in value.

Counterparty Risk. The Fund is subject to counterparty credit risk, which is the risk that the counterparty fails to perform on agreements with the Fund such as swap and option contracts, and reverse repurchase agreements.

(m)Distributions to Shareholders

The Fund declares and pays monthly distributions to common shareholders. These distributions 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 GAAP.

(n) New Accounting Pronouncements

In June 2014, the FASB issued an ASU that expands secured borrowing accounting for certain repurchase agreements. The ASU also sets forth additional disclosure requirements for certain transactions accounted for as sales, in order to provide financial statement users with information to compare to similar transactions accounted for as secured borrowings. The ASU is effective prospectively during interim or annual periods beginning after December 15, 2014. At this time, management is evaluating the implications of these changes on the financial statements.

Note 3 – Investment Management Agreement, Servicing Agreement and Other Agreements:

Pursuant to the Investment Management Agreement (the “Agreement”) between the Fund and the Investment Adviser, the Investment Adviser is responsible for the daily management for the Fund’s portfolio of investments, which includes buying and selling securities for the Fund, as well as investment research. The Investment Adviser will receive an annual fee from the Fund based on the average value of the Fund’s Managed Assets. Managed Assets means the total of assets of the Fund (including any assets attributable to borrowings in the use of financial leverage, if any) less the sum of accrued liabilities (other than debt representing financial leverage, if any). In addition, subject to the approval of the Fund’s Board of Trustees, a pro rata portion of the salaries, bonuses, health insurance, retirement benefits and similar employment costs for the time spent on Fund operations (other than the provision of services required under the Agreement) of all personnel employed by the Investment Adviser who devote substantial time to Fund operations may be reimbursed by the Fund to the Investment Adviser. For the six months ended April 30, 2015, the Investment Adviser was not reimbursed by the Fund for these items. The annual fee will be determined as follows:

(a) If the average value of the Fund’s Managed Assets (calculated monthly) is greater than $250 million, the fee will be a maximum amount equal to 0.54% of the average value of the Fund’s Managed Assets.

Pursuant to a Servicing Agreement between the Fund and Guggenheim Funds Distributors, LLC, the Fund’s servicing agent (the “Servicing Agent”), the Servicing Agent will act as servicing agent to the Fund. The Servicing Agent will receive an annual fee from the Fund, which will be based on the average value of the Fund’s Managed Assets. The fee will be determined as follows: (a) If the average value of the Fund’s Managed Assets (calculated monthly) is greater than $250 million, the fee will be a maximum amount equal to 0.21% of the average value of the Fund’s Managed Assets.

The Bank of New York Mellon (“BNY”) acts as the Fund’s custodian and accounting 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.

Rydex Fund Services, LLC (“RFS”), an affiliate of the Servicing Agent, provides fund administration services to the Fund. As compensation for these services RFS 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%

Certain officers and trustees of the Fund are also officers and directors of the Investment Adviser or Servicing Agent. 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 continue 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 avoids a 4% federal excise tax that is assessed on the amount of the under distribution.

As of April 30, 2015, the cost of investments and accumulated unrealized appreciation/depreciation on investments for federal income tax purposes were as follows:

			Net Tax	Net Tax
Cost of			Unrealized	Unrealized
Investments	Gross Tax	Gross Tax	Appreciation	Depreciation on
for Tax	Unrealized	Unrealized	on	Derivatives and
Purposes	Appreciation	Depreciation	Investments	Foreign Currency
$ 692,265,393	$ 31,952,151	$ (21,416,321)	$ 10,535,830	$ (491,959)

The differences between book basis and tax basis unrealized appreciation/(depreciation) are attributable to the tax deferral of losses on wash sales and income adjustments for tax purposes on certain convertible securities.

As of October 31, 2014 (the most recent fiscal year end for federal income tax purposes), the components of accumulated earnings/(losses) (excluding paid-in capital) on a tax basis were as follows:

Undistributed	Undistributed
Ordinary	Long-Term
Income/	Gains/
(Accumulated	(Accumulated
Ordinary Loss)	Capital Loss)
$ –	$ (93,671,361)

The differences between book basis and tax basis undistributed long-term gains/(accumulated capital losses) are attributable to the tax deferral of losses on wash sales and straddles.

As of October 31, 2014 (the most recent fiscal year end for federal income tax purposes), the Fund had a capital loss carryforward of $93,671,361 available to offset possible future capital gains. Of the capital loss carryforward, $92,379,718 expires on October 31, 2017 and $1,291,643 expires on October 31, 2019. For the year ended October 31, 2014 (the most recent fiscal year end for federal income tax purposes), the Fund utilized $19,505,358 of capital losses. Per the Regulated Investment Company Modernization Act of 2010, capital loss carryforwards generated in taxable years beginning after December 22, 2010 must be fully used before capital loss carryforwards generated in taxable years prior to December 22, 2010; therefore, under certain circumstances, capital loss carryforwards available as of the report date, if any, may expire unused.

For the year ended October 31, 2014 (the most recent fiscal year end for federal income tax purposes), the tax character of distributions paid, as reflected in the Statement of Changes in Net Assets, of $26,570,932 was ordinary income.

For all open tax years and all major jurisdictions, management of the Fund has concluded that there are no significant uncertain tax positions that would require recognition in the financial statements. Uncertain tax positions are tax positions taken or expected to be taken in the course of preparing the

AVK l ADVENT CLAYMORE CONVERTIBLE SECURITIES AND INCOME FUND SEMIANNUAL REPORT l 45

NOTES TO FINANCIAL STATEMENTS (Unaudited) continued

April 30, 2015

Fund’s tax returns that would not meet a more-likely-than not threshold of being sustained by the applicable tax authority and would be recorded as a tax expense in the current year. Open tax years are those that are open for examination by taxing authorities (i.e. generally the last four tax year ends and the interim tax period since then). Furthermore, management of the Trust is also not aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly change in the next twelve months.

Note 5 – Investments in Securities:

For the six months ended April 30, 2015, the cost of purchases and proceeds from sales of investments, excluding written options and short-term securities, were $386,271,432 and $383,228,018, respectively.

Note 6 – Derivatives:

(a) Covered Call and Put Options

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 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).

The Fund will follow a strategy of writing covered call options, which is a strategy designed to produce income from option premiums and offset a portion of a market decline in the underlying security. This strategy will be the Fund’s principal investment strategy in seeking to pursue its primary investment objective. The Fund will only “sell” or “write” options on securities held in the Fund’s portfolio. It may not sell “naked” call options, i.e., options on securities that are not held by the Fund or on more shares of a security than are held in the Fund’s portfolio. The Fund will consider a call option written with respect to a security underlying a convertible security to be covered so long as (i) the convertible security, pursuant to its terms, grants to the holders of such security the right to convert the convertible security into the underlying security and (ii) the convertible security, upon conversion, will convert into enough shares of the underlying security to cover the call option written by the Fund.

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. A writer of a put option is exposed to the risk of loss if fair value of the underlying securities declines, but profits only to the extent of the premium received if the underlying security increases in value. The writer of an option has no control over the time when it may be required to fill 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.

(b) Forward Foreign Currency Exchange Contracts

A forward foreign currency exchange 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.

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.

At April 30, 2015, the following forward foreign currency exchange contracts were outstanding:

In December 2011, the Financial Accounting Standards Board (“FASB”) issued an Accounting Standards Update (“ASU”) No. 2011-11: Disclosures about Offsetting Assets and Liabilities (“netting”) on the Statements of Assets and Liabilities that are subject to master netting arrangements or similar agreements. ASU 2011-11, was amended by ASU No. 2013-01, clarifying which investments and transactions are subject to the netting disclosure. The scope of the disclosure requirements is limited to derivative instruments, repurchase agreements and reverse repurchase agreements, and securities

borrowing and securities lending transactions to the extent they are subject to an enforceable master netting arrangement or similar agreement. This information will enable users of the Fund’s financial statements to evaluate the effect or potential effect of netting arrangements on the Fund’s financial position. The ASU is effective for financial statements with fiscal years beginning on or after January 1, 2013, and interim periods within those fiscal years. The Fund adopted the disclosure requirement on netting for the current reporting period.

For financial reporting purposes, the Fund does not offset financial assets and financial liabilities across derivative types that are subject to master netting arrangements or similar agreements on the Statement of Assets and Liabilities.

Note 7 – Capital:

Common Shares

The Fund has an unlimited amount of common shares, $0.001 par value, authorized and 23,580,877 issued and outstanding. In connection with the Fund’s dividend reinvestment plan, the Fund did not issue shares during the six months ended April 30, 2015, or the year ended October 31, 2014. As of April 30, 2015, Advent Capital Management LLC, the Fund’s Investment Adviser, owned 11,379 shares of the Fund.

Preferred Shares

On June 19, 2003, the Fund’s Board of Trustees authorized the issuance of Auction Market Preferred Shares (“AMPS” or “Preferred Shares”), as part of the Fund’s leverage strategy. AMPS issued by the Fund had seniority over the common shares.

On July 24, 2003, the Fund issued 2,150 shares of Series M7, 2,150 shares of Series T28, 2,150 shares of Series W7 and 2,150 shares of Series TH28, each with a liquidation value of $25,000 per share plus accrued dividends. In addition, on March 16, 2004, the Fund issued 1,200 shares of Series F7 and 1,200 shares of Series W28 each with a liquidation value of $25,000 per share plus accrued dividends.

Note 8 – Borrowings:

On November 9, 2012, the Fund entered into a five year margin loan agreement with an approved counterparty whereby the counterparty has agreed to provide secured financing to the Fund and the Fund will provide pledged collateral to the lender. The interest rate on the amount borrowed is 1.74%. On December 20, 2012, the Fund borrowed $170,000,000 under the margin loan agreement and $170,000,000 is outstanding in connection with the margin loan agreement as of period end. An unused commitment fee of 0.25% is charged on the difference between the $170,000,000 margin loan agreement and the amount borrowed. If applicable, the unused commitment fee is included in Interest Expense on the Statement of Operations.

On December 20, 2012, the Fund entered into a three year fixed rate reverse repurchase agreement. Under a reverse repurchase agreement, the Fund temporarily transfers possession of a portfolio instrument to another party, such as a bank or broker-dealer, in return for cash. At the same time, the Fund agrees to repurchase the instrument at an agreed upon time and price, which reflects an interest payment. Such agreements have the economic effect of borrowings. The Fund may enter into such agreements when it is able to invest the cash acquired at a rate higher than the cost of the agreement, which would increase earned income. When the Fund enters into a reverse repurchase agreement, any fluctuations in the market value of the instruments transferred to another party or the instruments in which the proceeds may be invested would affect the market value of the Fund’s assets. As a result, such transactions may increase fluctuations in the market value of the Fund’s assets. On December 20, 2012, the Fund entered into a $92,000,000 reverse repurchase agreement with Bank of America Merrill Lynch which expires on December 20, 2015. The $92,000,000 is outstanding in connection with the reverse repurchase agreement as of period end. The interest rate on the reverse repurchase agreement is 1.63%.

As of April 30, 2015, the Fund has collateral of $418,869,941 in connection with borrowings and reverse repurchase agreements.

The Fund’s use of leverage creates special risks that may adversely affect the total return of the Fund. The risks include but are not limited to: greater volatility of the Fund’s net asset value and market price; fluctuations in the interest rates on the leverage; and the possibility that increased costs associated with the leverage, which would be borne entirely by the holder’s of the Fund, may reduce the Fund’s total return. The Fund will pay interest expense on the leverage, thus reducing the Fund’s total return. This expense may be greater than the Fund’s return on the underlying investment.

The agreements governing the margin loan and reverse repurchase agreement include usual and customary covenants. These covenants impose on the Fund asset coverage requirements, collateral requirements, investment strategy requirements, and certain financial obligations. These covenants place limits or restrictions on the Fund’s ability to (i) enter into additional indebtedness with a party other than the lender, (ii) change its fundamental investment policy, or (iii) pledge to any other party, other than to the lender, securities owned or held by the Fund over which the lender has a lien. In addition, the Fund is required to deliver financial information to the lender within established deadlines, maintain an asset coverage ratio (as defined in Section 18(g) of the 1940 Act) greater than 300%, comply with the rules of the stock exchange on which its shares are listed, and maintain its classification as a “closed-end fund company” as defined in the 1940 Act.

Note 9 – 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 require 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.

DIVIDEND REINVESTMENT PLAN (Unaudited)

April 30, 2015

Unless the registered owner of common shares elects to receive cash by contacting Computershare Shareowner Services LLC (the “Plan Administrator”), all dividends declared on common shares of the Fund will be automatically reinvested by the Plan 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.

AVK l ADVENT CLAYMORE CONVERTIBLE SECURITIES AND INCOME FUND SEMIANNUAL REPORT l 57

DIVIDEND REINVESTMENT PLAN (Unaudited) continued

April 30, 2015

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, Computershare Shareowner Services LLC, P.O. Box 30170 College Station, TX 77842-3170; Attention: Shareholder Services Department, Phone Number: (866) 488-3559.
