DEAR SHAREHOLDER

We thank you for your investment in the Advent Claymore Convertible Securities and Income Fund (the “Fund” or “AVK”). This report covers the Fund’s performance for the 12 months ended October 31, 2018.

The mergers of Advent Claymore Convertible Securities and Income Fund II (“AGC”) and Advent/Claymore Enhanced Growth & Income Fund (“LCM”) with and into AVK was completed prior to the opening of the New York Stock Exchange on August 27, 2018. More information about the mergers appear later in this report.

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 four lines of business—long-only strategies, hedge funds, closed-end funds, and private credit. As of October 31, 2018, Advent managed approximately $9 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% of its managed assets in non-convertible income securities. The Fund may invest without limitation in foreign securities. The Fund also uses a strategy of writing (selling) covered call options on up to 25% of the securities held in the portfolio, thus generating option writing premiums.

All AVK returns cited—whether based on net asset value (“NAV”) or market price—assume the reinvestment of all distributions. For the 12-month period ended October 31, 2018, the Fund generated a total return based on market price of -5.22% and a total return of -0.34% based on NAV. As of October 31, 2018, the Fund’s market price of $13.93 represented a discount of 14.01% to NAV of $16.20.

DEAR SHAREHOLDER (Unaudited) continued	October 31, 2018

Past performance is not a guarantee of future results. All NAV returns include the deduction of management fees, operating expenses, and all other Fund expenses. The market price of the Fund’s shares fluctuates from time to time, and may be higher or lower than the Fund’s NAV.

The Fund paid a distribution each month of the annual period. The most recent monthly distribution, $0.1172, represents an annualized distribution of 10.10% based upon the last closing market price of $13.93 on October 31, 2018.

There is no guarantee of any future distribution or that the current returns and distribution rate will be maintained. The Fund’s distribution rate is not constant and the amount of distributions, when declared by the Fund’s Board of Trustees, is subject to change based on the performance of the Fund. Please see Note 2(n) on page 50 for more information on distributions for the period.

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 70 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 (Unaudited)	October 31, 2018

The portfolio managers of Advent Claymore Convertible Securities and Income Fund (the “Fund” or “AVK”) are Tracy Maitland, Chief Investment Officer of Advent Capital Management, LLC (“Advent” or the “Investment Adviser”) and Paul Latronica, Managing Director of Advent. They are primarily responsible for the day-to-day management of the Fund’s portfolio. Mr. Maitland and Mr. Latronica are supported by teams of investment professionals who make investment decisions for the Fund’s core portfolios of convertible bonds, the Fund’s high yield securities investments and the Fund’s leverage allocation, respectively. In the following interview, the management team discusses the convertible securities and high yield markets and Fund performance for the 12-month period ended October 31, 2018.

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% of its managed assets in nonconvertible income securities. The Fund may invest without limitation in foreign 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 exchange currency 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.

In connection with the mergers of Advent Claymore Convertible Securities and Income Fund II (“AGC”) and Advent/Claymore Enhanced Growth and Income Fund (“LCM”) with and into the Fund in August 2018, the Fund adopted non-fundamental investment policies limiting investments in illiquid securities to 20% of managed assets and investments in private securities to 15% of managed assets. Private securities may be privately-offered convertible securities, privately-offered non-convertible income securities, and any attached or related privately-offered warrants or equity-linked securities. The Fund does not expect to invest more than 2.5% of its managed assets in any single private security at the time of investment.

QUESTIONS & ANSWERS (Unaudited) continued	October 31, 2018

Discuss Advent’s investment approach.

Advent’s approach involves core portfolios of convertible bonds that are managed, subject to the Fund’s investment policies and restrictions, in a manner similar to that of Advent’s Balanced Convertible Strategy and Global Balanced Convertible Strategy, which seek high total returns by investing in a portfolio of U.S. dollar convertible securities and global convertible securities, respectively, that provide equity-like returns while seeking to limit downside risk.

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

Advent 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 incorporates leverage and operates 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.

As mentioned, the Fund has adopted a non-fundamental investment policy allowing Advent to invest up to 15% of managed assets in private securities. Advent intends to invest in private securities primarily to enhance the Fund’s current income.

Can you elaborate on the merger?

In March 2018, the Boards of Trustees for each of the Fund, AGC and LCM, approved the merger of each of AGC and LCM into the Fund. Expected benefits for shareholders of all three funds included lower expense ratios, greater secondary market trading liquidity, greater flexibility in leverage management, and other benefits resulting from a single larger fund entity.

Shareholders of each of AGC, LCM and the Fund approved the mergers at a meeting in July 2018, and the mergers closed prior to market open on August 27, 2018. Shareholders of each of AGC and LCM received new shares of the Fund based on NAV ratios as of August 24, 2018.

Each fund had similar (but not identical) investment policies. Each fund emphasized investments in convertible securities and non-convertible income-producing securities, combined with a strategy of writing (selling) covered call options on a portion of the securities held in the fund’s portfolio, thus generating option writing premiums. The Fund’s investment objective continues to be to provide total return through a combination of capital appreciation and current income.

No fundamental investment policies of the Fund has changed as a result of the mergers. The Fund will continue to invest at least 80% of its managed assets in a diversified portfolio of convertible and non-convertible income-producing securities with at least 30% of its managed assets in convertible securities and up to 70% of its managed assets in non-convertible income-producing securities.

Please describe the economic and market environment over the last 12 months.

Corporate bond and equity markets acted in differing fashions as the fiscal year progressed. For most of the fiscal year, a strong U.S. economy helped by tax reform, strong enterprise and consumer spending, and surging corporate profits powered equity and convertible bond markets higher. Except for a correction in January which seemed to have origins in inflation fears, the U.S. equity market continued higher for most months through the summer of 2018. U.S. unemployment continued falling, powering consumer confidence higher, and various manufacturing indicators, such as capacity utilization and purchasing manager indices, extended positive trends. While the Treasury bond markets were limited by continued U.S. Federal Reserve (the “Fed”) rate hikes, the U.S. high-yield market managed to offset this through the summer, as corporate profits helped credit spreads lessen.

Later in the fiscal year, however, the cumulation of a number of individual market developments conspired to create a second market correction, whose outcome remains uncertain as the fiscal year closed. Trade negotiation tensions between the U.S. and China rose as the U.S. implemented threatened increases in tariffs for a large percentage of Chinese imports and signaled new tariffs on the remainder. Strong corporate profits, partly powered by lower corporate income tax rates, gave way to fear of difficult comparisons in the following year, especially as the industrial economy slowed in many foreign economies. A number of country-specific economic crises in emerging markets shook confidence in the emerging market bond and equity asset classes and risk assets in general. Prices for many commodities, notably crude oil, fell victim to decelerating global demand and the rising dollar, hurting equities and corporate bond prices. Fears of tightening financial conditions became an issue in corporate bond markets.

This all said, the U.S. economy thus far, while affected in sectors with higher Chinese or emerging market exposure, has proven resilient, with third calendar quarter Gross Domestic Product remaining impressively high at 3.5%, confirmed in a final figure in late November. Consumer spending has remained robust and assisted the retail sector. Speculation of an intermediate-term end to Fed rate hikes may help interest-rate sensitive sectors such as banking, insurance, real estate, and housing, should the yield curve resteepen again, in a classic soft-landing scenario. Although European economies have notably decelerated during 2018, hurt by higher automotive emission regulations and lower export demand, valuations are attractive for the equity markets, and eventual resolution of the United Kingdom’s exit from the European Union and the Italian budget negotiations may help as the new fiscal year progresses. Fiscal and monetary stimulus from the Chinese authorities may help sentiment recover in China as trade negotiations continue.

How did the Fund perform in this environment?

AVK l ADVENT CLAYMORE CONVERTIBLE SECURITIES AND INCOME FUND ANNUAL REPORT l 7


QUESTIONS & ANSWERS (Unaudited) continued	October 31, 2018

What contributed to performance?

The Fund’s largest asset class, U.S. convertible bonds, had strong performance in the period as the ICE Bank of America (“BofA”) Merrill Lynch U.S. Convertible Index rose 3.67% for the fiscal year 2018. The U.S. equity market, illustrated by the Standard & Poor’s 500^®(“S&P 500”) Index, advanced 7.35% with dividends reinvested in the year. The ratio of convertible returns to equity returns of 0.50 was slightly lower than past years and reflects the mix of the convertible bond universe toward mid and small-capitalization issuers, both of which had returns lower than the S&P 500 Index.

The U.S. high-yield corporate bond market returned 0.86% per the performance of the ICE BofA Merrill Lynch U.S. High Yield Index. Fed interest rate hikes took Treasury yields, one of the bases for valuation of corporate bonds, higher, offsetting most of the income generated.

Although international debt and equity indices generally performed worse in the fiscal year than U.S. ones, the introduction of more foreign investments in the Fund as a result of the mergers did not have an incremental negative effect on returns. Convertible index returns since the mergers were negative for both U.S. and global markets and were slightly more negative in the U.S. through the end of the fiscal year.

The Fund has continued in the just-completed fiscal year a policy of hedging the currency risk of securities issued in foreign currencies. During the fiscal year, the U.S. Dollar Index, a trade-weighted measure of the U.S. dollar’s performance relative to currencies of American trading partners, rose from 94.6 to 97.1, generally indicating that foreign-currency securities depreciated when translated back to U.S. dollars. Hedging activities of the Fund were able to recover much of this depreciation and took on a greater relevance as AVK assumed the global convertible securities of the Acquired Funds late in the fiscal year in a time while the U.S. dollar continued to rise.

Please discuss the Fund’s distributions.

The Fund paid a distribution each month of the period. The most recent monthly distribution, $0.1172, represents an annualized distribution of 10.10% based upon the last closing market price of $13.93 on October 31, 2018.

The Fund currently anticipates that some of the 2018 distributions will consist of income and some will be a return of capital. A final determination of the tax character of distributions paid by the Fund in 2018 will be reported to shareholders in January 2019 on form 1099-DIV.

While the Fund generally seeks to pay distributions that will consist primarily of investment company taxable income and net capital gain, because of the nature of the Fund’s investments and changes in market conditions from time to time, or in order to maintain a more stable distribution level over time, the distributions paid by the Fund for any particular period may be more or less than the amount of net investment income from that period. If the Fund’s total distributions in any year exceed the amount of its investment company taxable income and net capital gain for the year, any such excess would generally be characterized as a return of capital for U.S. federal income tax purposes.

A return of capital distribution is in effect a partial return of the amount a shareholder invested in the Fund. A return of capital does not necessarily reflect the Fund’s investment performance and should not be confused with “yield” or “income.” A return of capital distribution decreases the Fund’s total assets and, therefore, could have the effect of increasing the Fund’s expense ratio. Please see Note 2(n) on page 50 for more information on distributions for the period.

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 October 31, 2018, consisted of $387 million in borrowings and reverse repurchase agreements with a related average interest rate of 3.31%, and was approximately 41% of the Fund’s total managed assets. During the fiscal year, the Fund refinanced its prior line of

AVK l ADVENT CLAYMORE CONVERTIBLE SECURITIES AND INCOME FUND ANNUAL REPORT l 9


QUESTIONS & ANSWERS (Unaudited) continued	October 31, 2018

credit, entered into new fixed-rate terms for a substantial majority of the borrowings, and assumed the borrowings and reverse repurchase agreement financing of AGC and LCM as part of the mergers.

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 NAV return for the Fund was below the cost of leverage for the 12 months. Although Advent looks at funds deployed from borrowings differently than funds which use the shareholder equity base, on this simple metric, the Fund’s leverage was not beneficial to shareholders for the fiscal period. Advent continues to seek attractive and relatively lower-risk opportunities to invest borrowings and plans to continue taking advantage of the yield curve and interest rate environment for the benefit of shareholders.

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

Volatility during the fiscal year 2018 increased from the low levels that prevailed in the prior year. The CBOE VIX Volatility Index, or “VIX” for its ticker, averaged 14.8, rebounding from a multi-year low in fiscal 2017 of 11.7, and generally similar to levels prevailing prior to fiscal 2017. As volatility levels rose late in the fiscal year, with uncertainties introduced with U.S. midterm elections, tariff negotiations, economic slowdowns in certain foreign nations, and normalization of the Fed balance sheet, the Fund took advantage by writing more call options on equity positions. When volatility is higher, the income generated from call option writing is larger than at other times, making for a more favorable trade-off in deciding whether to cap upside participation in equities held.

How were the Fund’s total investments allocated among asset classes during the 12 months ended October 31, 2018, and what did this mean for performance?

On October 31, 2018, the Fund’s total investments were invested approximately 48.8% in convertible bonds, convertible preferred securities, and mandatory convertibles; 37.9% in corporate bonds; 9.1% in equities; 3.2% in cash and cash equivalents; and 1.0% in senior floating rate interests.

On October 31, 2017, the Fund’s total investments were invested approximately 47.8% in convertible bonds, convertible preferred securities, and mandatory convertibles; 39.5% in corporate bonds; 7.7% in equities; 3.9% in cash and cash equivalents; and 1.1% in senior floating rate interests.

Asset class allocations were broadly unchanged from the end of the prior fiscal year to the end of this fiscal year. In between, the Fund made a slightly higher allocation toward equities, sourced from convertibles and high-yield, as strong economic growth in the U.S. coupled with higher corporate profit growth due partly to tax reform led to more opportunities for capital appreciation in the equity markets. Higher borrowing costs also led the asset allocation sleeve to invest more capital in higher-dividend equities and less in convertibles and BB high-yield securities, where spreads had become less attractive. As the fiscal year reached a close, the investing environment became more difficult, with fears over trade wars, slowing global economic growth, a Fed intent on continuing to normalize short-term interest rates, and currency fluctuations all leading to higher risk premia. By fiscal year end, the Fund had reduced its equity position to a level similar to the start of the fiscal year and returned allocations to convertibles and high-yield.

10 l AVK l ADVENT CLAYMORE CONVERTIBLE SECURITIES AND INCOME FUND ANNUAL REPORT


QUESTIONS & ANSWERS (Unaudited) continued	October 31, 2018

Although both of the Fund’s main asset classes had indices with positive returns for the fiscal year, the index returns were both at levels similar to or lower than the Fund’s borrowing costs, which limited NAV returns.

International investments rose from 13.0% at October 2017 to 22.1% at October 2018. A direct comparison is difficult to make as the Fund is now managed with an allocation to global convertible securities as a result of the mergers, and the Fund changed its country classification to reflect an issuer’s geographic risk rather than its country of incorporation, which reduced the international percentage. Although foreign equity markets generally performed worse than the U.S. equity market during the year, the returns from global convertible indices were slightly better (a lower loss) than that of U.S. convertible indices from the closing date of the merger until the end of the fiscal year. This is due to the lower delta and equity sensitivity of the global convertible universe compared to the domestic one.

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

Contrasting with last year, when the discussion of positive contributors was centered around technology and Internet issuers, this year the largest winners came from a number of economic sectors. In health care, the Fund benefitted from a number of investments in the device, biopharmaceutical, and software subsegments. Exact Sciences Corp. (0.4% of long-term investments at period end), the marketer of the Cologuard colorectal cancer DNA test, entered into a copromotion agreement of Cologuard with drug giant Pfizer, vastly expanding the adoption potential of the product and resulting in a leap in the convertible bonds. Sarepta Therapeutics, Inc. and its convertible bonds (0.2% of long-term investments at period end) also performed very well after the company presented far better early-stage data of its microdystrophin gene therapy program at its analyst day, strongly making a case that a large market exists to address those with muscular dystrophy. Convertibles in health care consultation services provider Teladoc Health, Inc. (0.3% of long-term investments at period end) also did well as the company’s virtual care delivery platform increased penetration into more users, clinical providers, and payment mechanisms.

Stock in leading retailer Walmart, Inc. (0.6% of long-term investments at period end) performed well as the company executed better on its online initiatives and made a savvy well-received acquisition in India’s Flipkart Online Services. Convertible bonds of computing processor maker Advanced Micro Devices, Inc. (0.1% of long-term investments at period end) jumped as the company began having success with a number of new products, challenging competitors Intel and NVidia in their respective areas of dominance. Various straight bonds of Bausch Health Companies, Inc. (1.1% of long-term investments at period end), formerly known as Valeant Pharmaceuticals, appreciated as financial results stabilized and the company’s new management focused on debt reduction instead of more acquisitions, helping the credit. Finally, stock and warrants in Magnolia Oil & Gas Corp. (0.2% of long-term investments at period end), which began as a special purpose acquisition company TPG Energy, performed well as management made its blank check purchase and was applauded for pursuing a financial model of lower debt and free cash flow generation.

AVK l ADVENT CLAYMORE CONVERTIBLE SECURITIES AND INCOME FUND ANNUAL REPORT l 11


QUESTIONS & ANSWERS (Unaudited) continued	October 31, 2018

Detractors were also interspersed throughout the investing universe. Mandatory convertibles of Altaba, Inc. (0.5% of long-term investments at period end), the former Yahoo!, with most of the value being stock in Chinese Internet giant Alibaba, declined as the Chinese economy slowed and markets feared the impact of the trade tensions between China and the U.S. This occurred despite Alibaba maintaining over 50% revenue growth throughout the year. Convertible bonds of the largest convertible issuer in the domestic market, Microchip Technology, Inc. (0.7% of long-term investments at period end), declined as the company ran into difficulties with its largest acquisition to date, Microsemi Corporation, and the leverage taken to effect the acquisition was a liability as the semiconductor industry entered into a downturn. The company’s longer-term track record on acquisitions has been excellent, and we believe the free cash flow generation will be substantial over coming quarters. Another large convertible issuer, DISH Network Corp. (0.5% of long-term investments at period end), fell during the year as a speculated acquisition by a larger telecommunications company to capture DISH’s large spectrum position did not occur, and DISH’s legacy business in rural satellite television began to experience net subscriber erosion.

Stock in casino operator Wynn Resorts Ltd. (0.4% of long-term investments at period end) also fell victim to the Chinese economy and corruption crackdowns as results out of the Macau and Las Vegas properties decelerated. Shares and straight bonds of heavy equipment lessor United Rentals, Inc. (0.7% of long-term investments at period end) fell as the company reported deceleration in its key metric of rental rate growth, though we believe the shares are distinctly undervalued currently. Mandatory convertibles in industrial and technology conglomerate Belden, Inc. (0.7% of long-term investments at period end) fell as the company experienced capacity constraints for industrial products and failed to realize a forecast acceleration in its broadcast equipment business.

NOTES TO FINANCIAL STATEMENTS	October 31, 2018

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 managed assets in a diversified portfolio of convertible securities and non-convertible income producing securities.

Note 2 – Accounting Policies:

The Fund operates as an investment company and accordingly follows the investment company accounting and reporting guidance of the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification Topic 946 Financial Services – Investment Companies.

The following significant accounting policies are in conformity with U.S. generally accepted accounting principles (“GAAP”) and are consistently followed by the Fund. This requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates. All time references are based on Eastern Time.

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 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. Equity securities not listed on a securities exchange or NASDAQ are valued at the mean of the closing bid and ask prices. 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. The value of over-the-counter (“OTC”) swap agreements entered into by the Fund is accounted for using the unrealized gain or loss on the agreements that is determined by marking the agreements to the last quoted value provided by an independent pricing service. Forward foreign currency exchange contracts are valued

42 l AVK l ADVENT CLAYMORE CONVERTIBLE SECURITIES AND INCOME FUND ANNUAL REPORT


NOTES TO FINANCIAL STATEMENTS continued	October 31, 2018

daily at current exchange rates. Swaps are valued daily by independent pricing services or dealers using the mid price. 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. The Fund values money market funds at net asset 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 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: market prices; sale prices; broker quotes; and models which derive prices based on inputs such as prices of securities with comparable maturities and characteristics, or based on inputs such as anticipated cash flows or collateral, spread over Treasuries, and other information analysis. There were no securities fair valued in accordance with such procedures established by the Board of Trustees as of October 31, 2018.

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 ANNUAL REPORT l 43


NOTES TO FINANCIAL STATEMENTS continued	October 31, 2018

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. OTC derivative contracts including forward currency contracts, swap 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.

(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.

44 l AVK l ADVENT CLAYMORE CONVERTIBLE SECURITIES AND INCOME FUND ANNUAL REPORT


NOTES TO FINANCIAL STATEMENTS continued	October 31, 2018

(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.

On October 31, 2018, there was no restricted cash.

(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, 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 translations 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

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


NOTES TO FINANCIAL STATEMENTS continued	October 31, 2018

seeks to generate current gains from option premiums as a means to enhance distributions payable to shareholders.

The Fund may purchase and sell (“write”) put and call options to manage and hedge risk within its portfolio and to gain long or short exposure to the underlying instrument. A purchaser of a put option has the right, but not the obligation, to sell the underlying instrument at an agreed upon price (“strike price”) to the option seller. A purchaser of a call option has the right, but not the obligation, to purchase the underlying instrument at the strike price from the option seller.

When an option is purchased, the premium paid by the Fund for options purchased is included on the Statement of Assets and Liabilities as an investment. The option is adjusted daily to reflect the current market value of the option and the change is recorded as Change in net unrealized appreciation/depreciation on Purchased options on the Statement of Operations. If the option is allowed to expire, the Fund will lose the entire premium it paid and record a realized loss for the premium amount. Premiums paid for options purchased which are exercised or closed are added to the amounts paid or offset against the proceeds on the underlying investment transaction to determine the realized gain (loss) or cost basis of the security.

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 Written options, 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.

The Fund is not subject to credit risk in options written as the counterparty has already performed its obligations by paying the premium at the inception of the contract.

(i) Swap Agreements

The Fund may engage in various swap transactions, including interest rate and credit default swaps to manage interest rate (e.g., duration, yield curve) and credit risk. The Fund may also use swaps as alternatives to direct investments. Swap transactions are negotiated contracts (“OTC swaps”) between a fund and a counterparty or centrally cleared (“centrally cleared swaps”) with a central clearinghouse through a Futures Commission Merchant (“FCM”), to exchange investment cash flows or assets at specified, future intervals.

Upfront payments made and/or received by the Fund is recognized as a realized gain or loss when the contract matures or is terminated. The value of an OTC swap agreement is recorded as either an asset or a liability on the Statement of Assets and Liabilities at the beginning of the measurement period. Upon entering into a centrally cleared swap, the Fund is required to deposit with the FCM cash or securities, which is referred to as initial margin deposit. Securities deposited as initial margin are designated on the Portfolio of Investments and cash deposited is recorded on the Statement of Assets and Liabilities. Daily changes in valuation of centrally cleared swaps, if any, are recorded as a variation margin receivable or payable on the Statement of Assets and Liabilities. The

46 l AVK l ADVENT CLAYMORE CONVERTIBLE SECURITIES AND INCOME FUND ANNUAL REPORT


NOTES TO FINANCIAL STATEMENTS continued	October 31, 2018

change in the value of swaps, including accruals of periodic amounts of interest to be paid or received on swaps, is reported as Change in net unrealized appreciation/depreciation on swap agreements on the Statement of Operations. A realized gain or loss is recorded upon payment or receipt of a periodic payment or payment made upon termination of a swap agreement.

The Fund may be required to post or receive collateral based on the net value of the Fund’s outstanding OTC swap contracts with the counterparty in the form of cash or securities. Daily movement of collateral is subject to minimum threshold amounts. Cash collateral posted by the Fund is included on the Statement of Assets and Liabilities as Restricted Cash. Collateral received by the Fund is held in escrow in segregated accounts maintained by the custodian.

(j) Forward Foreign Currency Exchange Contracts

The Fund enters 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 in realized gain (loss) on forward foreign currency exchange contracts on the Statement of Operations.

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

(k) 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. A loan is often administered by a bank or other financial institution (the “lender”) that acts as agent for all holders. The agent administers the terms of the loan, as specified in the loan agreement. The Fund may invest in multiple series or tranches of a loan, which may have varying terms and carry different associated risks. A Fund generally has no right to enforce compliance with the terms of the loan agreement with the borrower. As a result, a Fund may be subject to the credit risk of both the borrower and the lender that is selling the loan agreement. 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.

(l) Reverse Repurchase Agreements

In a reverse repurchase agreement, the Fund delivers 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

AVK l ADVENT CLAYMORE CONVERTIBLE SECURITIES AND INCOME FUND ANNUAL REPORT l 47


NOTES TO FINANCIAL STATEMENTS continued	October 31, 2018

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.

(m) 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 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

48 l AVK l ADVENT CLAYMORE CONVERTIBLE SECURITIES AND INCOME FUND ANNUAL REPORT


NOTES TO FINANCIAL STATEMENTS continued	October 31, 2018

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.

AVK l ADVENT CLAYMORE CONVERTIBLE SECURITIES AND INCOME FUND ANNUAL REPORT l 49


NOTES TO FINANCIAL STATEMENTS continued	October 31, 2018

(n) 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. If the Fund’s total distributions in any year exceed the amount of its investment company taxable income and net capital gain for the year, any such excess would generally be characterized as a return of capital for U.S. federal income tax purposes.

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.

(o) Indemnifications

Under the Fund’s organizational documents, its Trustees and Officers are indemnified against certain liabilities arising out of the performance of their duties to the Fund. In addition, throughout the normal course of business, the Fund enters into contracts that contain a variety of representations and warranties 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 and/or its affiliates that have not yet occurred. However, based on experience, the Fund expects the risk of loss to be remote.

Pursuant to the Investment Management Agreement (the “Agreement”) between the Fund and Advent Capital Management, LLC (“Advent” or 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 receives 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 year ended October 31, 2018, 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.

(b) If the average value of the Fund’s Managed Assets (calculated monthly) is $250 million or less, the fee will be a maximum amount equal to 0.55% 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”) will act as servicing agent to the Fund. The Servicing Agent will receive an annual fee of 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.

MUFG Investor Services (US), LLC (“MUIS”) provides fund administration services to the Fund. For providing the aforementioned services, MUIS and BNY are entitled to receive a monthly fee equal to an annual percentage of the Fund’s average daily managed assets.

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.

In order to present paid-in capital in excess of par and total distributable earnings or losses on the Statement of Assets and Liabilities that more closely represent their tax character, certain adjustments have been made to total distributable earnings or losses and paid-in capital. For the year ended October 31, 2018, the adjustments were to increase paid-in capital by $18,739,894 and decrease total distributable earnings (loss) by $18,739,894 due to the difference in the treatment for book and tax purposes of fund merger adjustments, distributions to shareholders, contingent payment debt instruments, real estate investment trusts, foreign currency, and partnerships.

As of October 31, 2018, the cost of securities for federal income tax purposes, the aggregate gross unrealized gain for all securities for which there was an excess of value over tax cost, and the aggregate gross unrealized less for all securities for which there was an excess of tax cost over value, were as follows:

	Gross Tax	Gross Tax	Net Tax
Tax	Unrealized	Unrealized	Unrealized
Cost	Appreciation	Depreciation	Depreciation
$959,721,025	$25,424,916	$(44,059,796)	$(18,634,880)

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

AVK l ADVENT CLAYMORE CONVERTIBLE SECURITIES AND INCOME FUND ANNUAL REPORT l 51


NOTES TO FINANCIAL STATEMENTS continued	October 31, 2018

As of October 31, 2018, the components of accumulated earnings/losses (excluding paid-in capital) on a tax basis were as follows:

Undistributed	Undistributed
Ordinary	Long-Term
Income/	Gains/	Net Unrealized
(Accumulated	(Accumulated	Appreciation/
Ordinary Loss)	Capital Loss)	(Depreciation)
$ —	$ (26,332,650)	$ (19,718,038)

The cumulative timing differences are primarily attributable to the tax deferral of losses on wash sales, straddle loss deferrals and additional income adjustments on certain convertible bonds.

As of October 31, 2018, the Fund had a capital loss carryforward available as shown in the table below, to offset possible future capital gains through the years indicated. 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.

			Total
Expires	Unlimited	Unlimited	Capital Loss
in 2019	Short-Term	Long-Term	Carryforward
$ 1,291,643	$ 19,067,444	$ 5,973,563	$ 26,332,650*

*	In accordance with Sections 382-384 of the Internal Revenue Code, a portion of Fund losses are subject to an annual limitation. This annual limitation is generally applicable to all of the capital loss carryforwards shown.

For the year ended October 31, 2018, the capital loss carryforward amounts expired and utilized were $2,393,946 and $20,839,939 respectively.

For the years ended October 31, 2018 and 2017, the tax character of distributions paid, as reflected in the Statement of Changes in Net Assets, of $13,035,462 and $17,334,952 was ordinary income and $18,468,343 and $11,167,493 was return of capital, respectively.

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 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 Fund 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 year ended October 31, 2018, the cost of purchases and proceeds from sales of investments, excluding written options and short-term securities, were $780,836,503 and $788,802,543, respectively.

Note 6 – Derivatives:

Derivatives are instruments whose values depend on, or are derived from, in whole or in part, the value of one or more other assets, such as securities, currencies, commodities or indices. Derivative instruments may be used to increase investment flexibility (including to maintain cash reserves while maintaining exposure to certain other assets), for risk management (hedging) purposes, to facilitate trading, to reduce transaction costs and to pursue higher investment returns. Derivative instruments may also be used to mitigate certain investment risks, such as foreign currency exchange rate risk, interest rate risk and credit risk. GAAP requires disclosures to enable investors to better understand how and why a Fund uses derivative instruments, how these derivative instruments are accounted for and their effects on the Fund’s financial position and results of operations.

The Fund may utilize derivatives for the following purposes:

Hedge – an investment made in order to seek to reduce the risk of adverse price movements in a security, by taking an offsetting position to protect against broad market moves.

Higher Investment Returns – the use of an instrument to seek to obtain increased investment returns.

Income – the use of any instrument that distributes cash flows typically based upon some rate of interest.

Speculation – the use of an instrument to express macro-economic and other investment views.

(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

AVK l ADVENT CLAYMORE CONVERTIBLE SECURITIES AND INCOME FUND ANNUAL REPORT l 53


NOTES TO FINANCIAL STATEMENTS continued	October 31, 2018

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.

The Fund’s exchange traded options are not subject to master netting arrangements (the right to close out all transactions traded with a counterparty and net amounts owed or due across the transactions).

(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 forward foreign currency exchange contracts.

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.

Swap agreements are contracts between parties in which one party agrees to make periodic payments to the other party (the “Counterparty”) based on the change in market value or level of a specified rate, index or asset. In return, the Counterparty agrees to make periodic payments to the first party based on the return of a different specified rate, index or asset. Swap agreements will usually be done on a net basis, the Fund receiving or paying only the net amount of the two payments.

Certain standardized swaps are subject to mandatory central clearing. Central clearing generally reduces counterparty credit risk and increases liquidity, but central clearing does not make swap transactions risk-free. Additionally, there is no guarantee that a Fund or an underlying fund could eliminate its exposure under an outstanding swap agreement by entering into an offsetting swap agreement with the same or another party.

The Fund may enter into swap agreements to manage its exposure to interest rates and/or credit risk, to generate income or to manage duration. 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, if any.

Credit default swap transactions involve the Fund’s agreement to exchange the credit risk of an issuer. A buyer of a credit default swap is said to buy protection by paying periodic fees in return for a contingent payment from the seller if the issuer has a credit event such as bankruptcy, a failure to pay outstanding obligations or deteriorating credit while the swap is outstanding. A seller of a credit

54 l AVK l ADVENT CLAYMORE CONVERTIBLE SECURITIES AND INCOME FUND ANNUAL REPORT


NOTES TO FINANCIAL STATEMENTS continued	October 31, 2018

default swap is said to sell protection and thus collects the periodic fees and profits if the credit of the issuer remains stable or improves while the swap is outstanding but the seller in a credit default swap contract would be required to pay an agreed upon amount, which approximates the notional amount of the swap, to the buyer in the event of an adverse credit event of the issuer.

There were no credit default swap agreements outstanding as of October 31, 2018.

(d) Summary of Derivatives Information

The Fund is required by GAAP to disclose: a) how and why a fund uses derivative instruments, b) how derivative 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.

The following table presents the types of derivatives in the Fund by location as presented on the Statement of Assets and Liabilities as of October 31, 2018.

The Fund’s derivatives contract held at October 31, 2018 are not accounted for as hedging instruments under GAAP.

Note 7 – Offsetting:

In the normal course of business, the Fund enters into transactions subject to enforceable master netting arrangements or other similar arrangements. Generally, the right to offset in those agreements allows the Fund to counteract the exposure to a specific counterparty with collateral received or delivered to that counterparty based on the terms of the arrangements. These arrangements provide for the right to liquidate upon the occurrence of an event of default, credit event upon merger or additional termination event.

Master Repurchase Agreements govern repurchase and reverse repurchase agreements between the Fund and the counterparties. Master Repurchase Agreements maintain provisions for, among other things, initiation, income payments, events of default and maintenance of collateral.

In order to better define their contractual rights and to secure rights that will help the Fund mitigate their counterparty risk, the Fund may enter into an International Swaps and Derivatives Association, Inc. Master Agreement (“ISDA Master Agreement”) or similar agreement with their derivative contract counterparties. An ISDA Master Agreement is a bilateral agreement between a Fund and a counterparty that governs OTC derivatives, including foreign exchange contracts, and typically contains, among other things, collateral posting terms and netting provisions in the event of a default and/or termination event. The provisions of the ISDA Master Agreement typically permit a single net payment in the event of a default (close-out netting) or similar event, including the bankruptcy or insolvency of the counterparty.

For derivatives traded under an ISDA Master Agreement, the collateral requirements are typically calculated by netting the mark to market amount for each transaction under such agreement and comparing that amount to the value of any collateral currently pledged by the Fund and the counterparty. For financial reporting purposes, cash collateral that has been pledged to cover obligations of the Fund and cash collateral received from the counterparty, if any, is reported separately on the Statement of Assets and Liabilities as restricted cash and deposits due to counterparties, respectively. Generally, the amount of collateral due from or to a counter party must exceed a minimum transfer amount threshold (e.g., $300,000) before a transfer is required to be

56 l AVK l ADVENT CLAYMORE CONVERTIBLE SECURITIES AND INCOME FUND ANNUAL REPORT


NOTES TO FINANCIAL STATEMENTS continued	October 31, 2018

made. To the extent amounts due to the Fund from its counterparties are not fully collateralized, contractually or otherwise, the Fund bears the risk of loss from counterparty nonperformance. The Fund attempts to mitigate counterparty risk by only entering into agreements with counterparties that it believes to be of good standing and by monitoring the financial stability of those counterparties.

For financial reporting purposes, the Fund does not offset derivative assets and derivative liabilities that are subject to netting arrangements in the Statement of Assets and Liabilities.

The following tables present derivative financial instruments and secured financing transactions that are subject to enforceable netting arrangements and offset in the Statement of Assets and Liabilities in conformity with GAAP.

Tender Offer

On August 9, 2017, the Fund announced the commencement of a tender offer by the Fund to acquire in exchange for cash up to 3,537,132 (approximately 15%) of the Fund’s outstanding shares at a price equal to 98.0% of the Fund’s NAV as of close of regular trading on the New York Stock Exchange on the business day immediately following the day the offer expires. A total of 8,775,224 shares were duly tendered and not withdrawn. Because the number of shares tendered exceeded 3,537,132 shares, the tender offer was oversubscribed. Therefore, in accordance with the terms and conditions specified in the tender offer, the Fund purchased shares from all tendering shareholders on a pro rata basis, disregarding fractions. Accordingly, on a pro rata basis, approximately 33% of shares for each shareholder who properly tendered shares were accepted for payment. The purchase price of properly tendered shares was $16.954 per share. Shares that were tendered but not accepted for purchase and shares that were not tendered remain outstanding. The Fund accepted 3,537,132 shares for payment. Final payment was made on September 13, 2017 in the aggregate amount equal to $59,968,535.

On August 27, 2018 the mergers of Advent Claymore Convertible Securities and Income Fund II (“AGC”) and Advent/Claymore Enhanced Growth and Income Fund (“LCM”) (the “Target Funds”) with and into AVK (the “Acquiring Fund”) were completed.

In the mergers, common shareholders of AGC and LCM, respectively, received newly-issued AVK common shares in tax-free transactions having an aggregate net asset value equal to the aggregate net asset value of their holdings of AGC and/or LCM common shares, as applicable, as determined at the close of business on August 24, 2018. Fractional AVK shares were not issued in the mergers and consequently cash was distributed for any such fractional amounts. Relevant details pertaining to the mergers are as follows:

Cost and Expenses

In connection with the mergers, the Target Funds and the Acquiring Fund incurred certain associated costs and expenses. Such amounts incurred by the Acquiring Fund are shown on the Statement of Assets and Liabilities and on the Statement of Operations as “Merger fees”. Costs specific to one or each of the funds were expensed to such fund as incurred. With respect to any expenses incurred in connection with the mergers that were not attributable to a specific fund, such expenses were allocated in proportion to the projected expense savings to be realized by each fund as a result of the Mergers. Of the estimated total costs of the mergers, approximately $579,000 was borne by AGC, $260,000 was borne by LCM and $86,000 was borne by AVK.

Pro Forma Results of Operations

Assuming the acquisition had been completed on November 1, 2017, the beginning of the fiscal reporting period of AVK, the pro forma results of operations for the period ended October 31, 2018, are as follows:


Acquiring Fund – Pro Forma Results from Operations (unaudited)	AVK
Net investment income (loss)	$	17,253,226
Net realized and unrealized gains (losses)	$	(17,845,647	)
Change in net assets resulting from operations	$	(592,421	)

Because the combined investment portfolios have been managed as a single integrated portfolio since the acquisition was completed, it is not practicable to separate the amounts of revenue and earnings of AGC and LCM that have been included in AVK’s Statement of Operations since August 27, 2018.

Note 10 – Borrowings:

On November 9, 2012, the Fund entered into a five year margin loan agreement with an approved counterparty whereby the counterparty agreed to provide secured financing to the Fund and the Fund provided pledged collateral to the lender. The interest rate on the amount borrowed was a fixed 1.74%. An unused commitment fee of 0.25% was charged on the difference between the $170,000,000 margin loan agreement and the amount borrowed. If applicable, the unused commitment fee was included in Interest Expense on the Statement of Operations. On December 20, 2012, the Fund borrowed $170,000,000 under the margin loan agreement. On December 15, 2017, the Fund terminated its existing margin loan agreement and transferred the $150,000,000 loan obligation to another approved counterparty.

On December 20, 2012, the Fund entered into a three year fixed rate reverse repurchase agreement. Under a reverse repurchase agreement, the Fund temporarily transferred 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 agreed 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 expired on December 20, 2015. The interest rate on the reverse repurchase agreement was a fixed 1.63%. On December 9, 2015, the Fund terminated its $92,000,000 reverse repurchase agreement with Bank of America Merrill Lynch. Concurrent with this termination on December 9th, the Fund entered into a $92,000,000 reverse repurchase agreement with Société Générale with an initial scheduled expiration date of December 9, 2017. The interest rate on the reverse repurchase agreement was a fixed 2.34%.

Concurrent with the termination of the margin loan on December 15, 2017, the Fund entered into a new senior secured credit agreement and an amended and restated reverse repurchase agreement with Société Générale. Under the terms of the new credit agreement, the Fund’s credit facility is as

60 l AVK l ADVENT CLAYMORE CONVERTIBLE SECURITIES AND INCOME FUND ANNUAL REPORT


NOTES TO FINANCIAL STATEMENTS continued	October 31, 2018

follows: 175-day evergreen maturity floating rate: $20,000,000; 3-year maturity fixed rate: $65,000,000; and 5-year maturity fixed rate: $65,000,000. The interest rates on the credit facility are as follows: 175-day evergreen floating: 3-month LIBOR + 0.85%; 3-year fixed: 3.43%; and 5-year fixed: 3.83%. The Fund pays a commitment fee on the undrawn portion of the 175-day evergreen facility in the amount of 0.25% per annum. If applicable, the unused commitment fee is included in Interest Expense on the Statement of Operations. Under the terms of the new reverse repurchase agreement, the Fund’s repurchase facility is as follows: 175-day evergreen floating: $13,000,000; 3-year fixed: $32,000,000; and 5-year fixed: $32,000,000. The interest rate on each tranche of the reverse repurchase agreement is the same as the rate on the credit-facility tranche of the same tenor and rate type. On March 14, 2018 the Fund reallocated its leverage with Société Générale, terminating its $20,000,000 floating rate margin loan and increasing its floating rate reverse repurchase agreement by $20,000,000.

On August 27, 2018, with the completion of the mergers of AGC and LCM into AVK, the Fund amended its leverage facilities with Société Générale in order to assume the leverage of the Target Funds. Under the terms of the amended credit agreement, the Fund’s credit facility is as follows:

3.48% 3-year maturity Margin Loan Agreement	$114,000,000
3.89% 5-year maturity Margin Loan Agreement	114,000,000
3-month LIBOR+0.85% Margin Loan Agreement	7,000,000
0.25% Undrawn Commitment Fee	30,000,000

Under the terms of the amended reverse repurchase agreement, the Fund’s repurchase facility is as follows:

3-month LIBOR+0.85% Floating Rate Reverse Repurchase Agreement	$54,000,000
3.43% 3-year maturity Reverse Repurchase Agreement	49,000,000
3.83% 5-year maturity Reverse Repurchase Agreement	49,000,000

As of October 31, 2018, there was $235,000,000 outstanding in connection with the Fund’s margin loan agreement. The average daily amount of borrowings on the margin loan during the year ended October 31, 2018 was $156,273,973 with a related average interest rate of 3.31%. As of October 31, 2018, there was $152,014,990 outstanding in connection with the Fund’s reverse repurchase agreements. The average daily amount of reverse repurchase agreements during the year ended October 31, 2018 was $99,657,534 with a related average interest rate of 3.30%. The average borrowings on the margin loan and reverse repurchase agreements for the year ended October 31, 2018 was $255,931,507 at an average interest rate of 3.31%.

NOTES TO FINANCIAL STATEMENTS continued	October 31, 2018

As of October 31, 2018, the total amount of securities segregated in connection with borrowings and reverse repurchase agreements was $750,614,035.

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. If the counterparty defaults or enters insolvency proceeding, realization or return of the collateral to the Fund may be delayed or limited.

Note 11 – Recent Regulatory Reporting Updates:

In August 2018, the U.S. Securities and Exchange Commission adopted amendments to certain disclosure requirements under Regulation S-X to conform to U.S. GAAP, including: (i) an amendment to require presentation of the total, rather than the components, of distributable earnings on the Statement of Assets and Liabilities; and (ii) an amendment to require presentation of the total, rather than the components, of distributions to shareholders, except for tax return of capital distributions, on the Statements of Changes in Net Assets.

As of October 31, 2018, management has implemented the amendments to Regulation S-X, which did not have a material impact on the Fund’s financial statements and related disclosures or impact the Fund’s net assets or results of operations.

Note 12 – Recent Accounting Pronouncements:

In March 2017, the Financial Accounting Standards Board issued an Accounting Standards Update, ASU 2017-08, Receivables – Nonrefundable Fees and Other Costs (Subtopic 310-20), Premium Amortization on Purchased Callable Debt Securities (the “ASU”) which amends the amortization period for certain purchased callable debt securities held at a premium, shortening such period to the earliest call date. The ASU does not require any accounting change for debt securities held at a discount; the discount continues to be amortized to maturity. The ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. At this time, management is evaluating the implications of these changes on the financial statements.

The ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. At this time, management is evaluating the implications of these changes on the financial statements.

In our opinion, the financial statements present fairly, in all material respects, the financial position of the Fund as of October 31, 2018, the results of its operations and its cash flows for the year then ended, the changes in its net assets for each of the two years in the period ended October 31, 2018 and the financial highlights for each of the five years in the period ended October 31, 2018 in conformity with accounting principles generally accepted in the United States of America.

We conducted our audits of these financial statements in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our procedures included confirmation of securities owned as of October 31, 2018 by correspondence with the custodian, transfer agent and brokers; when replies were not received from brokers, we performed alternative auditing procedures.

DIVIDEND REINVESTMENT PLAN (Unaudited)	October 31, 2018

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 Computershare Trust Company, N.A. (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, nonparticipants 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.

70 l AVK l ADVENT CLAYMORE CONVERTIBLE SECURITIES AND INCOME FUND ANNUAL REPORT


DIVIDEND REINVESTMENT PLAN (Unaudited) continued	October 31, 2018

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 Trust Company, N.A., P.O. Box 30170 College Station, TX 77842-3170; Attention: Shareholder Services Department, Phone Number: (866) 488-3559 or online at www.computershare.com/investor.

CONSIDERATIONS REGARDING ANNUAL REVIEW OF THE
INVESTMENT MANAGEMENT AGREEMENT (Unaudited)	October 31, 2018

In discussing the factors and other considerations summarized below, the Board noted that it generally receives, reviews and evaluates information concerning the performance of the Advent Claymore Convertible Securities and Income Fund (“AVK” or, the “Fund”) and the services and personnel of Advent Capital Management, LLC (“Advent”) and its affiliates at quarterly meetings of the Board. While emphasis might be placed on information concerning the investment performance of the Fund, the Fund’s fees and expenses in comparison with other funds’ fees and expenses and other matters at the meeting at which the renewal of the Investment Management Agreement is considered, the process of evaluating the Fund’s investment management arrangement is an ongoing one. The Board did not identify any one particular factor that was controlling or of paramount importance in its deliberations and each individual Trustee may have weighed the information provided differently. The information below represents a summary of certain aspects of the more detailed discussions held by the Board and does not necessarily include all information considered by the Trustees.

Nature, Extent and Quality of Services

The Independent Trustees received and considered various data and information regarding the nature, extent and quality of services provided to AVK by Advent under the Investment Management Agreement. The Independent Trustees reviewed and considered the information provided by Advent in response to a detailed series of requests submitted on behalf of the Independent Trustees by their independent legal counsel. The Independent Trustees were provided with, among other things, information about the background, experience and expertise of the management and other personnel of Advent and the services provided by Advent to the Fund. The Independent Trustees discussed the quality of the services provided. The compliance history of Advent was discussed, along with the ability of Advent to provide services to the Fund.

The Independent Trustees evaluated the capabilities of Advent, including information regarding its resources and its ability to attract and retain highly qualified investment and other professionals. The Independent Trustees also considered the commitment of Advent to the Fund. The Independent Trustees discussed the portfolio managers at Advent responsible for portfolio management for the Fund, including the involvement of Mr. Maitland, and other personnel at Advent.

Based on the above factors, together with those referenced below, the Independent Trustees concluded that they were satisfied with the nature, extent and quality of the investment management services provided to AVK by Advent.

Fund Performance and Expenses

The Independent Trustees considered the performance results for AVK on a market price and net asset value basis over various time periods. They also considered the results of the Fund in comparison to the performance results of other closed-end funds that were determined to be similar to the Fund in terms of investment strategy (the “Peer Group”). They recognized that the number of other funds in the Peer Group was small and that, for a variety of reasons, including exposures to types of assets that significantly vary from those held by the Fund, the Peer Group comparisons may

72 l AVK l ADVENT CLAYMORE CONVERTIBLE SECURITIES AND INCOME FUND ANNUAL REPORT


CONSIDERATIONS REGARDING ANNUAL REVIEW OF THE
INVESTMENT MANAGEMENT AGREEMENT (Unaudited) continued	October 31, 2018

have limited usefulness in evaluating Fund performance. The Board also was aware that the performance benchmark indexes may not be useful comparisons due to the fact that the securities included in the benchmarks may include convertibles, high yield or other securities with characteristics unlike those purchased by the Fund or in amounts that vary materially from the Fund’s typical holdings.

The Board noted that AVK’s three- and five-year performance records were in-line with peer averages but that AVK ranked in the middle of the Peer Group for the one-year period ended October 31, 2017. AVK also trailed its convertible benchmark index during the one-year period but outperformed its high-yield index during this period.

The Board noted that it had continuing discussions with Fund management about the performance of the Fund. The Board noted that the Fund is managed consistent with its stated policies and strategies and that the Fund would tend to underperform in relation to the Peer Group funds with high common stock exposure in rising equity markets. In addition, the Board was advised of the negative impact of raising and holding cash to satisfy a tender offer for the Fund in 2017 and the added costs for addressing shareholder activism and the tender. That the reduced size of the Fund resulted in a reduction in leverage, thereby affecting performance, was also considered. The Independent Trustees considered the steps management has historically taken, and the activities it presently undertakes, to seek to improve performance, and will continue to monitor performance on an on-going basis. The Board discussed the repositioning of the Fund’s portfolio and the impact of the implementation of a sleeve investment approach on performance.

The Board also reviewed information about the discount at which the Fund’s shares have traded as compared with its Peer Group.

The Independent Trustees received and considered information regarding AVK’s total expense ratio relative to the Peer Group, noting that the Fund generally had a higher expense ratio (based on common assets) than funds in the Peer Group. The Independent Trustees acknowledged that the expense ratio of AVK was often higher than expense ratios of certain Peer Group funds for several reasons: (1) because of AVK’s use of leverage and longer-term borrowings, (2) because certain funds in the Peer Group had no leverage or lower leverage and therefore reported lower expense ratios, and (3) because of the relatively small size of the Fund in relation to funds in the Peer Group. The Board considered that in the most recent year, the Fund had incurred extraordinary expenses related to shareholder activism and the tender offer conducted in settlement with activists. The costs of leverage were also considered and the potential benefits of the continued use of leverage were considered. The Independent Trustees also noted that expense ratio comparisons with the Peer Group was difficult because the items included in other funds’ expenses may differ from those of the Fund.

Based on the above considerations, discussions and other factors, the Independent Trustees concluded that the overall performance results and expense comparisons supported the re-approval of the Investment Management Agreement of AVK.

CONSIDERATIONS REGARDING ANNUAL REVIEW OF THE
INVESTMENT MANAGEMENT AGREEMENT (Unaudited) continued	October 31, 2018

Investment Management Fee Rate

The Independent Trustees reviewed and considered the contractual investment management fee rate for AVK (the “Management Agreement Rate”) payable by AVK to Advent for investment management services. Additionally, the Independent Trustees received and considered information comparing the Management Agreement Rate with those of the funds in the Peer Group. The Independent Trustees also received and considered information about the nature, extent and quality of services and fee rates offered by Advent to its other clients. In particular, Advent confirmed that the Fund differs from certain other accounts advised by Advent in that it is more complex to manage, requires greater resources from Advent and differs in terms of investment strategy and use of leverage. The Independent Trustees also noted the differing services provided by Advent to the Fund in relation to those typically provided to private funds and separate accounts. The Independent Trustees were also aware of the regulatory, reputational, compliance and operational risks faced by Advent in providing services to the Fund, which are generally greater than presented in providing services to clients other than registered funds.

Based on the totality of the information they reviewed, the Independent Trustees concluded that the fees were fair and reasonable.

Profitability

The Independent Trustees received and considered an estimated profitability analysis of Advent based on the Management Agreement Rate. The Independent Trustees also discussed with Advent representatives the methodology used to determine profitability. The Independent Trustees considered the nature of the services provided, their benefits to the Fund, and the extensive resources that would be required to provide those services. In addition, the Independent Trustees considered whether any direct or indirect collateral benefits inured to Advent as a result of its affiliation with the Fund. In the case of Advent, the Independent Trustees were apprised of the extent of use of Fund brokerage commissions to purchase research services consistent with regulatory requirements. The Independent Trustees concluded that, in light of the costs of providing investment management and other services to AVK, the profits and other ancillary benefits that Advent received with regard to providing these services to AVK were not unreasonable.

Economies of Scale

The Independent Trustees received and considered information regarding whether there have been economies of scale with respect to the management of AVK, whether AVK has appropriately benefited from any economies of scale, and whether there is potential for realization of any further economies of scale. It was noted that, because the Fund is a closed-end fund, any increase in asset levels generally would have to come from material appreciation through investment performance and the Independent Trustees concluded that the opportunity to benefit from economies of scale was diminished in the context of closed-end funds. The Independent Trustees noted that, in fact, the Fund had decreased in size following the tender offer in settlements with shareholder activists.

Investment Philosophy

Advent believes that superior returns can be achieved while reducing risk by investing in a diversified portfolio of global equity, convertible and high-yield securities. Advent seeks securities with attractive risk/reward characteristics. Advent employs a bottom-up security selection process across all of the strategies it manages.

Item 4. Principal Accountant Fees and Services.

(a) Audit Fees: the aggregate fees billed for professional services rendered by the principal accountant for the audit of the registrant’s annual financial statements or services that are normally provided by the accountant in connection with statutory and regulatory filings or engagements were $140,000 and $98,350 for the fiscal years ended October 31, 2018, and October 31, 2017, respectively.

(e) Audit Committee Pre-Approval Policies and Procedures.

(1) In accordance with Rule 2-01(c)(7) of Regulation S-X, the Audit Committee pre-approves all of the Audit and Tax Fees of the registrant. All of the services described in paragraphs 4(b) through 4(d) above were approved by the Audit Committee in accordance with paragraph (c)(7) of Rule 2-01 of Regulation S-X.

The Audit Committee has adopted written policies relating to the pre-approval of the audit and non-audit services performed by the registrant’s independent auditors. Unless a type of service to be provided by the independent auditors has received general pre-approval, it requires specific pre-approval by the Audit Committee. Under the policies, on an annual basis, the Audit Committee reviews and pre-approves the services to be provided by the independent auditors without having to obtain specific pre-approval from the Audit Committee. The Audit Committee has delegated pre-approval authority to the Audit Committee Chairperson. In addition, the Audit Committee pre-approves any permitted non-audit services to be provided by the independent auditors to the registrant’s investment adviser or any entity controlling, controlled by, or under common control with the adviser if such services relate directly to the operations and financial reporting of the registrant.

AUDIT COMMITTEE PRE-APPROVAL POLICY OF

ADVENT CLAYMORE CONVERTIBLE SECURITIES AND INCOME FUND

Statement of Principles

The Audit Committee (the “Audit Committee”) of the Board of Trustees (the “Board”) of Advent Claymore Convertible Securities and Income Fund (the “Trust,”) is required to pre-approve all Covered Services (as defined in the Audit Committee Charter) in order to assure that the provision of the Covered Services does not impair the auditors’ independence. Unless a type of service to be provided by the Independent Auditor (as defined in the Audit Committee Charter) is pre-approved in accordance with the terms of this Audit Committee Pre-Approval Policy (the “Policy”), it will require specific pre-approval by the Audit Committee or by any member of the Audit Committee to which pre-approval authority has been delegated.

This Policy and the appendices to this Policy describe the Audit, Audit-Related, Tax and All Other services that are Covered Services and that have been pre-approved under this Policy. The appendices hereto sometimes are referred to herein as the “Service Pre-Approval Documents”. The term of any such pre-approval is 12 months from the date of pre-approval, unless the Audit Committee specifically provides for a different period. At its June meeting of each calendar year, the Audit Committee will review and re-approve this Policy and approve or re-approve the Service Pre-Approval Documents for that year, together with any changes deemed necessary or desirable by the Audit Committee. The Audit Committee may, from time to time, modify the nature of the services pre-approved, the aggregate level of fees pre-approved or both. The Audit Committee

hereby directs that each version of this Policy and the Service Pre-Approval Documents approved, re-approved or amended from time to time be maintained with the books and records of the Trust.

Delegation

In the intervals between the scheduled meetings of the Audit Committee, the Audit Committee delegates pre-approval authority under this Policy to the Chairman of the Audit Committee (the “Chairman”). The Chairman shall report any pre-approval decisions under this Policy to the Audit Committee at its next scheduled meeting. At each scheduled meeting, the Audit Committee will review with the Independent Auditor the Covered Services pre-approved by the Chairman pursuant to delegated authority, if any, and the fees related thereto. Based on these reviews, the Audit Committee can modify, at its discretion, the pre-approval originally granted by the Chairman pursuant to delegated authority. This modification can be to the nature of services pre-approved, the aggregate level of fees approved, or both. The Audit Committee expects pre-approval of Covered Services by the Chairman pursuant to this delegated authority to be the exception rather than the rule and may modify or withdraw this delegated authority at any time the Audit Committee determines that it is appropriate to do so.

Pre-Approved Fee Levels

Fee levels for all Covered Services to be provided by the Independent Auditor and pre-approved under this Policy will be established annually by the Audit Committee and set forth in the Service Pre-Approval Documents. Any increase in pre-approved fee levels will require specific pre-approval by the Audit Committee (or the Chairman pursuant to delegated authority).

Audit Services

The terms and fees of the annual Audit services engagement for the Trust are subject to the specific pre-approval of the Audit Committee. The Audit Committee will approve, if necessary, any changes in terms, conditions or fees resulting from changes in audit scope, Trust structure or other matters.

In addition to the annual Audit services engagement specifically approved by the Audit Committee, any other Audit services for the Trust not listed in the Service Pre-Approval Document for the respective period must be specifically pre-approved by the Audit Committee (or the Chairman pursuant to delegated authority).

Audit-Related Services

Audit-Related services are assurance and related services that are not required for the audit, but are reasonably related to the performance of the audit or review of the financial statements of the Trust and, to the extent they are Covered Services, the other Covered Entities (as defined in the Audit Committee Charter) or that are traditionally performed by the Independent Auditor. Audit-Related services that are Covered Services and are not listed in the Service Pre-Approval Document for the respective period must be specifically pre-approved by the Audit Committee (or the Chairman pursuant to delegated authority).

Tax Services

The Audit Committee believes that the Independent Auditor can provide Tax services to the Covered Entities such as tax compliance, tax planning and tax advice without impairing the auditor’s independence. However, the Audit Committee will not permit the retention of the

Independent Auditor in connection with a transaction initially recommended by the Independent Auditor, the sole business purpose of which may be tax avoidance and the tax treatment of which may not be supported in the Internal Revenue Code and related regulations. Tax services that are Covered Services and are not listed in the Service Pre-Approval Document for the respective period must be specifically pre-approved by the Audit Committee (or the Chairman pursuant to delegated authority).

All Other Services

All Other services that are Covered Services and are not listed in the Service Pre-Approval Document for the respective period must be specifically pre-approved by the Audit Committee (or the Chairman pursuant to delegated authority).

Procedures

Requests or applications to provide Covered Services that require approval by the Audit Committee (or the Chairman pursuant to delegated authority) must be submitted to the Audit Committee or the Chairman, as the case may be, by both the Independent Auditor and the Chief Financial Officer of the respective Covered Entity, and must include a joint statement as to whether, in their view, (a) the request or application is consistent with the SEC’s rules on auditor independence and (b) the requested service is or is not a non-audit service prohibited by the SEC. A request or application submitted to the Chairman between scheduled meetings of the Audit Committee should include a discussion as to why approval is being sought prior to the next regularly scheduled meeting of the Audit Committee.

(2) None of the services described in each of Items 4 (b) through (d) were approved by the Audit Committee pursuant to paragraph (c)(7)(C) of Rule 2-01 of Regulation S-X.

(f) Not applicable.

(g) The aggregate non-audit fees billed by the registrant's accountant for services rendered to the registrant, the registrant’s investment adviser (not including a sub-adviser whose role is primarily portfolio management and is sub-contracted with or overseen by another investment adviser) and/or any entity controlling, controlled by, or under common control with the adviser that provides ongoing services to the registrant that directly related to the operations and financial reporting of the registrant were $17,510 and $17,000 for the fiscal years ended October 31, 2018, and October 31, 2017, respectively.
