Dear SHAREHOLDER|

President and Chief Executive Officer

We thank you for your investment in the Advent Claymore Convertible Securities
and Income Fund (the "Fund"). This report covers the Fund's performance for the
fiscal year ended October 31, 2008.

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 will invest 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 60% of its managed assets in
convertible securities and up to 40% in lower grade, non-convertible income
securities. Convertible securities represented 73.7% of the portfolio as of
October 31, 2008.

All Fund returns cited--whether based on net asset value ("NAV") or market
price--assume the reinvestment of all distributions. For the 12-month period
ending October 31, 2008, the Fund provided a total return based on market price
of -41.96% and a return of -51.06% based on NAV. As of October 31, 2008, the
Fund's market price of $13.11 represented a premium of 4.71% to NAV of $12.52.

The Fund currently implements its leverage strategy primarily through issuance
of Auction Market Preferred Shares ("AMPS") and additionally through total
return swaps on bank loans. The broad auction-rate preferred securities market
remains essentially frozen. The auctions for nearly all auction-rate preferred
shares, including AMPS such as those issued by the Fund, are failing. We believe
that this increase in failed auctions is simply a liquidity issue. Investors
need to be aware that a failed auction is not a default, nor does it require the
redemption of a fund's auction-rate preferred shares. Provisions in the offering
documents of the Fund's AMPS provide a mechanism to set a maximum rate in the
event of a failed auction, and, thus, investors will continue to be entitled to
receive payment for holding these AMPS. This maximum rate is determined based
upon a multiple of or a spread to LIBOR--whichever is greater.

The Fund has six series of AMPS, three that auction each week and three that
auction every 28 days. The auctions for the Fund's AMPS have failed since
mid-February 2008, as have auctions of most AMPS. The established maximum rates
during this period were based on a spread of 125 basis points over the
applicable LIBOR rates, with the maximum rates ranging from 3.27% to 5.94%. From
mid-October 2008 and into November, LIBOR declined dramatically. As a result,
recent maximum rates have been below 2.50%. Subsequent to the reporting period
on December 1, 2008, the Fund announced a redemption of $13 million of its AMPS.
These redemptions are scheduled to take place between December 23, 2008 and
January 14, 2009. We will continue to evaluate the benefits and impacts of
leverage on the Fund, as well as explore other methods of utilizing leverage.

On December 1, 2008, the Fund declared its December monthly dividend of $0.0939
per share, reflecting a reduction of $0.0779 per share from the previous monthly
distribution rate of $0.1718 per share, which was maintained throughout the
Fund's fiscal year ended October 31, 2008. The Fund's management believes that
reducing the distribution is a necessary step to enhance our ability to maintain
and potentially grow the Fund's net asset value--which should benefit the Fund's
shareholders over time. This reduced dividend represents an annualized
distribution rate of 8.59% based upon the closing market price of $13.11 on
October 31, 2008.

There is no guarantee of any future distributions or that the current returns
and distribution rate will be maintained.

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 27 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 NAV, subject to an IRS limitation
that the purchase price cannot be more than 5% below 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 DRIP plan effectively
provides an income-averaging technique, which causes shareholders to accumulate
a larger number of Fund shares when the share price is depressed rather than
when the price is higher.

The following Questions & Answers section provides more information about the
factors that affected the Fund's performance during the past twelve months.

We are honored that you have chosen the Advent Claymore Convertible Securities
and Income Fund as part of your investment portfolio. For the most up-to-date

& ANSWERS


QUESTIONS & ANSWERS|

Advent Claymore Convertible Securities and Income Fund (the "Fund") is managed
by a team of seasoned professionals at Advent Capital Management, LLC,
("Advent"), led by Tracy V. Maitland, Advent's President and Chief Investment
Officer. In the following interview, Mr. Maitland discusses the convertible
securities and high-yield markets and the performance of the Fund during its
fiscal year ended October 31, 2008.


--------------------------------------------------------------------------------
WILL YOU REMIND US OF THIS FUND'S OBJECTIVES AND HOW YOU SEEK TO ACHIEVE THEM?

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 will invest 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 60% of its managed assets in
convertible securities and may invest up to 40% in lower grade, non-convertible
income securities. Historically, convertible securities have generally provided
returns similar to equity returns with lower risk. This is possible because a
significant portion of the return of convertible securities generally comes from
yield. Moreover, movement in the price of the convertible security tends to be
more sensitive to appreciation of the underlying stock than to setbacks in the
price of the stock.

More than half of the convertible market and a large portion of the Fund's
convertible investments are in securities issued by growth
companies--particularly companies within the healthcare, financial and
technology sectors. Growth companies generally issue convertible bonds or
convertible preferred stocks as a means of raising capital to build their
businesses. Convertibles represent something of a compromise between equity and
debt as a way to raise capital for growth; convertibles generally have a lower
interest rate than straight bonds, but entail less dilution than issuing common
stock. Financial companies, while not presently considered growth companies,
also issue a fair amount of convertible securities--typically convertible
preferreds with more attractive yields and higher credit ratings. By offering
preferreds, companies can raise capital while helping to keep their credit
ratings higher than if they offered bonds. This is because issuing bonds would
increase the proportion of debt on an issuing company's balance sheet, making a
downgrade in credit rating more likely, while preferred stock is classified as
equity. Credit ratings are especially important to financial companies, since a
lower credit rating generally results in higher borrowing costs.

The Fund's flexibility to shift between convertibles and high-yield bonds helps
provide diversification on an asset, sector and security level. Among the
attractions of convertible securities are that they generally offer a yield
advantage over common stocks; they have tended to move up in tandem with
equities in strong markets; and the yield advantage has historically provided
inherent downside protection in weaker markets.


--------------------------------------------------------------------------------
PLEASE TELL US ABOUT THE ECONOMIC AND MARKET ENVIRONMENT OVER THE LAST 12
MONTHS.

In the mid-year report for this Fund, we described the six-month period ended
April 30, 2008, as a time of economic uncertainty and turmoil in capital
markets. Since that time, there has been pronounced further deterioration in the
economy and in equity and debt markets throughout the world.

The U.S. economy, as measured by real gross domestic product, contracted in the
third quarter of 2008, and most economists are now predicting several quarters
of negative real growth. Unemployment has risen sharply; consumer spending has
dropped; and business investment has weakened as even those firms in healthy
financial condition have become reluctant to expand in an environment of
heightened uncertainty and tighter credit.

The present crisis originated with the end of a housing boom fueled by
excessively easy credit. As the prices of houses fell, losses on mortgage-based
securities mounted, eroding the capital of financial institutions and initiating
a vicious cycle of deleveraging. The process began in late 2007 as a correction
in the sub-prime mortgage market, but it has intensified markedly, with profound
implications for the entire U.S. economy and related effects on global markets
and economies. In fact, many foreign economies, especially those that depend on
exports for growth, have weakened more than the U.S.

Credit markets have become so intolerant of risk that they are essentially
frozen. In an effort to alleviate the financial crisis, the U.S. government has
taken unprecedented actions, including instituting temporary insurance on money
market funds, expanding access by financial institutions to the Federal Reserve
(the "Fed"), and investing directly in some financial institutions. Some large
financial firms have been allowed to fail, while others were rescued, and
takeovers of troubled financial firms have been arranged. Other central banks
have also taken robust action to support banking systems and stimulate economic
growth.

In this very difficult environment, markets have been extremely volatile, and
essentially all asset classes except U.S. Treasury securities have had negative
returns. The Standard & Poor's 500 Index(1), which is generally regarded as a
good indicator of the broad stock market, returned -36.10% for the 12-month
period ended October 31, 2008. World equity markets performed even worse: the
MSCI World Index(2), which measures performance of world equity markets,
returned -41.51% during the same time period.

Convertible securities, which in the past have been less volatile than straight
equities, performed almost as poorly: the return of the Merrill Lynch All U. S.
Convertibles Index(3) was -35.42% for the same time period. A major reason for
negative performance was selling by hedge funds, which had made leveraged
investments in convertibles while shorting the underlying common stocks. Unable
to get the financing they had used in the past, hedge funds had to sell
convertibles into a market with little demand, and prices dropped precipitously.

In the bond market, we have seen unprecedented spreads between yields of
investment grade and high-yield corporate bonds and U.S. Treasury securities,
which are considered not to carry credit risk. In this disastrous market, the
only bonds with positive returns were those with little or no credit risk: the
Lehman 10-20 Year U.S. Treasury Index(4) returned 4.13%. The Lehman Brothers
Aggregate Bond Index(5), which measures return of the high-quality U.S. bond
market as a whole, returned 0.30%, but the return of the Merrill Lynch High
Yield Master II Index(6), which measures performance of the high-yield bond
market, was -25.40%. All Index returns are for the 12-month period ended October
31, 2008.


--------------------------------------------------------------------------------
HOW DID THE FUND PERFORM IN THIS ENVIRONMENT?

All Fund returns cited--whether based on net asset value ("NAV") or market
price--assume the reinvestment of all distributions. For the 12-month period
ending October 31, 2008, the Fund provided a total return based on market price
of -41.96% and a return of -51.06% based on NAV. As of October 31, 2008, the
Fund's market price of $13.11 represented a premium of 4.71% to NAV of $12.52. A
year earlier, at October 31, 2007, the Fund's closing market price was $25.15
and NAV was $28.23. The market value of the Fund's shares fluctuates from time
to time, and it may be higher or lower than the Fund's NAV.


--------------------------------------------------------------------------------
WHAT WERE THE MAJOR INVESTMENT DECISIONS THAT AFFECTED THE FUND'S PERFORMANCE?

In recent months convertibles have experienced the greatest setback in recorded
history. Records don't exist for the period of the market crash of the late
1920s and early 1930s, but today's conditions have been much worse than in the
worst periods of the 1970s and 1980s. In a severe bear market, convertibles
barely outperformed equities. So the Fund's 73.7% position in convertibles was
an impediment to performance.

Many convertibles, even those with short maturities, have been trading at higher
yields than the straight bonds of the same companies. This is an anomaly that
apparently reflects forced selling of convertibles by hedge funds and in our
opinion suggests superior returns from convertibles in the future.

Within the convertibles portion of the portfolio, a significant position in the
health care industry helped performance. The relative strength in health care
was more than offset by large exposure to the financial sector, which had been a
good source of relatively high income and equity appreciation potential for the
Fund over the years. Indeed, health care and financials typically are the two
largest sectors in the Fund.

While health care investments did relatively well, the definition of relatively
good performance in the second half of the Fund's fiscal year was a small
loss--rather than a strong gain. Our largest healthcare investment is in Teva
Pharmaceutical Finance LLC (3.6% of long-term investments), the world's largest
generic drug company; we swapped out of the 1.75% convertible bond for the 0.25%
"C" series convertible bond, which offered potential downside protection without
sacrificing upside potential. We raised Teva to the largest position in the Fund
on October 31. We also did relatively well with our investment in Watson
Pharmaceuticals, Inc. (1.6% of long-term investments), another generic drug
company, which declined only modestly during the market rout. We began to reduce
our position in Watson, however, because the convertible appeared to no longer
offer sufficient appreciation potential.

Unfortunately, financial stocks were hard hit, especially in the second half of
the Fund's fiscal year. We accumulated a small position in Lehman Brothers
Holdings Inc. (no securities were held in portfolio at period end) as the firm
appeared to be turning around--and consequently we were caught in the bankruptcy
filing, which drove the price of the Lehman convertible to pennies on the
dollar. We also suffered further losses in our reduced position in XL Capital
Ltd. (0.3% of long-term investments), a reinsurance company that appeared to be
turning around under new management, but continued to fall into disfavor in the
market.

We sold our small positions in Federal National Mortgage Association ("Fannie
Mae") and Federal Home Loan Mortgage Corporation ("Freddie Mac") before the
convertible preferreds of these two entities became essentially worthless. (No
securities of these entities were held in the portfolio at period end.) The lack
of protection for the preferreds in the government rescues of these two
companies was reflected in lower prices of other

convertible preferreds--particularly convertible preferreds in the financial
sector--which are a major investment of the Fund.

All was not woe in the financial sector, however. We began accumulating
convertible bonds of Merrill Lynch & Co., Inc. (1.1% of long-term investments)
in mid-July. The September 14 announcement that Merrill Lynch would be acquired
by Bank of America Corporation (1.6% of long-term investments) caused these
preferreds to move up, helping to add to performance.

The Fund also made a modest profit on Boston Private Financial Holdings, Inc.
(0.5% of long-term investments) as the market began to recognize that the
convertible bonds--puttable July 15, 2009--are highly likely to prove "money
good" and as the company announced that it had bought back some of the
convertibles.

Our allocation to high-yield bonds was also a negative impact as credit spreads
widened dramatically, though not quite so negative as convertibles. Since
high-yield bonds are more difficult to hedge than convertibles, they are less
appealing to hedge funds, thus have not felt the extreme selling pressure
experienced by convertibles. Over this period, the Fund was underweight high
yield relative to its history. At inception, approximately 40% of the Fund's
assets were invested in high-yield bonds; high-yield bonds represented 10.4% of
total investments as of October 31, 2007, and 11.4% as of October 31, 2008. The
Fund would have faired better over this period with a greater weight in
high-yield bonds.

The Fund has also had some exposure to leveraged bank loans, which were under
pressure. Like convertibles, bank loans were widely held by hedge funds, often
with considerable leverage. And, like convertibles, they have been subject to
forced selling as hedge funds have found it necessary to raise cash. We believe
that the current prices of some bank loans still in the portfolio are
attractive, and such holdings are likely to perform better as different types of
investment entities begin to identify investment opportunities in these
instruments.


--------------------------------------------------------------------------------
HOW HAS THE FUND'S LEVERAGE STRATEGY AFFECTED PERFORMANCE?

The Fund utilizes leverage (borrowing) as part of its investment strategy. The
purpose of leverage is 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 currently implements its leverage strategy primarily through
the issuance of Auction Market Preferred Shares ("AMPS").

Through the fiscal year ended October 31, 2008, the Fund's AMPS leverage was
maintained at a constant level of $275 million. We were conservative in not
maximizing leverage at times when the Fund's NAV was much higher than it is now.
In retrospect, this was a wise move because the recent setback has caused the
Fund's leverage to increase as a percentage of asset value.

The broad auction-rate preferred securities market remains essentially frozen.
The auctions for nearly all auction-rate preferred shares, including AMPS such
as those issued by the Fund, are failing. We believe that this increase in
failed auctions is simply a liquidity issue. Investors need to be aware that a
failed auction is not a default, nor does it require the redemption of a fund's
auction-rate preferred shares. Provisions in the offering documents of the
Fund's AMPS provide a mechanism to set a maximum rate in the event of a failed
auction, and, thus, investors will continue to be entitled to receive payment
for holding these AMPS. This maximum rate is determined based upon a multiple of
or a spread to LIBOR--whichever is greater.

The Fund has six series of AMPS, three that auction each week and three that
auction every 28 days. The auctions for the Fund's AMPS have failed since
mid-February 2008, as have auctions of most AMPS. The established maximum rates
during this period were based on a spread of 125 basis points over the
applicable LIBOR rates, with the maximum rates ranging from 3.27% to 5.94%. From
mid-October and into November, LIBOR declined dramatically. As a result, recent
maximum rates have been below 2.50%. We will continue to evaluate the benefits
and impacts of leverage on the Fund, as well as exploring other methods of
utilizing leverage. On December 1, 2008, the Fund announced a partial at-par
redemption of its outstanding AMPS, liquidation preference $25,000 per share.
The Fund will redeem $13 million of its outstanding AMPS. The redemption price
will be equal to the liquidation preference per share, plus accumulated but
unpaid dividends as of the applicable redemption date. See the Fund's website
for redemption schedule.

Subsequent to the reporting period, on December 1, 2008, the Fund announced a
partial redemption of its AMPS. The Fund will redeem $13 million of its
outstanding AMPS between December 23, 2008 and January 14, 2009. The redemption
price will be equal to the liquidation preference per share, plus accumulated
but unpaid dividends as of the redemption date.

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. During the recent market volatility, leverage has
been a handicap. Leverage adds value only when the return on securities
purchased exceeds the cost of leverage.

We believe that it seems more likely that leverage will again add to
performance, given the current relatively low rates on AMPS--and the relatively
low prices and high yields on our investments. Although the use of Financial
Leverage by the Fund may create an opportunity for increased return for the
common shares, it also results in additional risks and can magnify the effect of
any losses. If the income and gains earned on securities purchased with the
Financial Leverage proceeds are greater than the cost of the Financial Leverage,
the common shares' return will be greater

than if Financial Leverage had not been used. Conversely, if the income or gains
from the securities purchased with the Financial Leverage proceeds are less than
the cost of the Financial Leverage, the return of the common shares will be less
than if Financial Leverage had not been used. There is no assurance that a
Financial Leveraging strategy will be successful.

WHAT IS YOUR CURRENT OUTLOOK FOR THE MARKETS AND THE FUND?

It is always disappointing to report a negative return, as nearly all funds have
in the recent market setback. As difficult as the market has been over the last
year, we believe that current market conditions provide many attractive
opportunities for this Fund, which has the ability to invest at a time when many
other investors are forced to sell holdings regardless of value.

A major advantage of investing in convertible securities is the feature of
asymmetry in the convertible market: convertibles tend to capture more of the
upside in a positive market than they lost on the downside in a negative market.
This feature makes convertibles very attractive to hedge funds, which, as
mentioned above, have invested heavily in these securities, providing a huge
source of liquidity in this market for the past few years. However, in recent
months, with many hedge funds in trouble, forced selling has put significant
pressure on the market for convertibles.

The positive aftermath of the disappointing performance in the recent
convertible market is that, we believe, the upside potential from convertibles
is now greater. Yields are higher, most issues are trading at discounts from
par, and conversion premiums are reasonable. We feel confident that over time
our diligence in security selection will continue to help the Fund's performance
both by providing favorable returns in rising markets and by providing
protection against down markets. Our two key asset classes--convertibles and
high-yield securities--historically have had much lower volatility and downside
risk than common stocks. Our proprietary credit analysis is intended to enable
us to invest in companies with what we believe are stable-to-improving
fundamentals and to avoid deteriorating situations that could be especially
dangerous during weak economic environments. Over time, convertible securities
have historically provided equity-like returns at lower risk by capturing much
of the appreciation of common stocks, while yielding more than equities and
experiencing less price deterioration during market corrections.

================================================================================
The conversion premium reflects the market price of a convertible relative to
the market value of the common shares into which the convertible security can be
converted. For example, a bond trading at a par value of $1,000 that is
convertible into 20 shares trading at $40 would have a conversion premium of 25%
over its conversion value of $800. The lower the conversion premium, the more
upside there is for convertible investors. If the stock performs poorly, the
convertible normally provides downside protection based on its yield and its
fixed-income value.

AVK RISKS AND OTHER CONSIDERATIONS

The views expressed in this report reflect those of the Portfolio Managers only
through the report period as stated on the cover. These views are subject to
change at any time, based on market and other conditions and should not be
construed as a recommendation of any kind. The material may also contain
forward-looking statements that involve risk and uncertainty, and there is no
guarantee they will come to pass. There can be no assurance that the Fund will
achieve its investment objectives. The value of the Fund will fluctuate with the
value of the underlying securities. Historically, closed-end funds often trade
at a discount to their net asset value. The Fund is subject to investment risk,
including the possible loss of the entire amount that you invest. Past
performance does not guarantee future results.

CONVERTIBLE SECURITIES. The Fund is not limited in the percentage of its assets
that may be invested in convertible securities. Convertible securities generally
offer lower interest or dividend yields than non-convertible securities of
similar quality. The market values of convertible securities tend to decline as
interest rates increase and, conversely, to increase as interest rates decline.
However, the convertible security's market value tends to reflect the market
price of the common stock of the issuing company when that stock price is
greater than the convertible's "conversion price, " which is the predetermined
price at which the convertible security could be exchanged for the associated
stock.

SYNTHETIC 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.

LOWER GRADE SECURITIES. The Fund may invest an unlimited amount in lower grade
securities. Investing in lower grade securities (commonly known as "junk bonds")
involves additional risks, including credit risk. Credit risk is the risk that
one or more securities in the Fund's portfolio will decline in price, or fail to
pay interest or principal when due, because the issuer of the security
experiences a decline in its financial status.

LEVERAGE RISK. Certain risks are associated with the leveraging of common stock.
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.

INTEREST RATE RISK. In addition to the risks discussed above, convertible
securities and non-convertible income securities are subject to certain risks,
including:

o if interest rates go up, the value of convertible securities and
nonconvertible income securities in the Fund's portfolio generally will decline;

o 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; and

AVK | Advent Claymore Convertible Securities and Income Fund | QUESTIONS &
ANSWERS continued


o during periods of rising interest rates, the average life of certain types of
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.

ILLIQUID INVESTMENTS. The Fund may invest without limit in illiquid securities.
The Fund may also invest without limit in Rule 144A Securities. Although many of
the Rule 144A Securities in which the Fund invests may be, in the view of the
Investment Manager, liquid, if qualified institutional buyers are unwilling to
purchase these Rule 144A Securities, they may become illiquid. Illiquid
securities may be difficult to dispose of at a fair price at the times when the
Fund believes it is desirable to do so. The market price of illiquid securities
generally is more volatile than that of more liquid securities, which may
adversely affect the price that the Fund pays for or recovers upon the sale of
illiquid securities.

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 (1) news and events unique to a country or region (2) smaller
market size, resulting in lack of liquidity and price volatility (3) certain
national policies which may restrict the Fund's investment opportunities.

STRATEGIC TRANSACTIONS. The Fund may use various other investment management
techniques that also involve certain risks and special considerations, including
engaging in hedging and risk management transactions, including interest rate
and foreign currency transactions, options, futures, swaps, caps, floors, and
collars and other derivatives transactions.

AUCTION MARKET PREFERRED SHARES (AMPS) RISK. The AMPS are redeemable, in whole
or in part, at the option of the Fund on any dividend payment date for the AMPS,
and are subject to mandatory redemption in certain circumstances. The AMPS are
not listed on an exchange. You may buy or sell AMPS only through an order placed
at an auction with or through a broker-dealer that has entered into an agreement
with the auction agent and the Fund or in a secondary market maintained by
certain broker dealers. These broker-dealers are not required to maintain this
market, and it may not provide you with liquidity.

In addition to the risks described above, the Fund is also subject to:
Management Risk, Market Disruption Risk and Anti-Takeover Provisions. Please see
www.claymore.com/avk for a more detailed discussion about Fund risks and
considerations.

AVK | Advent Claymore Convertible Securities and Income Fund

Notes to FINANCIAL STATEMENTS|OCTOBER 31, 2008


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.


Note 2 - ACCOUNTING POLICIES:

The preparation of the financial statements in accordance with U.S. generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts and disclosures in the financial
statements. Actual results could differ from these estimates.

The following is a summary of significant accounting policies followed by the
Fund.

(A) VALUATION OF INVESTMENTS

Equity securities listed on an exchange are valued at the last reported sale
price on the primary exchange on which they are traded. Equity securities traded
on an exchange for which there are no transactions on a given day are valued at
the mean of the closing bid and asked prices. Securities traded on NASDAQ are
valued at the NASDAQ Official Closing Price. Equity securities not listed on a
securities exchange or NASDAQ are valued at the mean of the closing bid and
asked prices. Debt securities are valued by independent pricing services or
dealers using the mean of the closing bid and asked prices for such securities
or, if such prices are not available, at prices for securities of comparable
maturity, quality and type. For those securities where quotations or prices are
not available, valuations are determined in accordance with procedures
established in good faith by the Board of Trustees. Futures contracts are valued
using the settlement price established each day on the exchange on which they
are traded. Short-term securities with remaining maturities of 60 days or less
are valued at amortized cost, which approximates market value.

(B) INVESTMENT TRANSACTIONS AND INVESTMENT INCOME

Investment transactions are accounted for on the trade date. Realized gains and
losses on investments are determined on the identified cost basis. Dividend
income is recorded on the ex-dividend date and interest income is recorded on an
accrual basis. Discounts or premiums on debt securities purchased are accreted
or amortized to interest income over the lives of the respective securities
using the effective interest method.

(C) CURRENCY TRANSLATION

Assets and liabilities denominated in foreign currencies are translated into
U.S. dollars at the mean of the bid and asked price of respective exchange rates
on the last day of the period. Purchases and sales of investments denominated in
foreign currencies are translated at the exchange rate on the date of the
transaction.

The Fund does not isolate that portion of the results of operations resulting
from changes in foreign exchange rates on investments from the fluctuations
arising from changes in market prices of securities held. Such fluctuations are
included with the net realized and unrealized gain or loss from investments.

Foreign exchange realized gain or loss resulting from the holding of a foreign
currency, expiration of a currency exchange contract, difference in exchange
rates between the trade date and settlement date of an investment purchased or
sold, and the difference between dividends or interest actually received
compared to the amount shown in a Fund's accounting records on the date of
receipt is shown as net realized gains or losses on foreign currency
transactions in the Fund's Statement of Operations.

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

(D) SWAPS
A swap is an agreement to exchange the return generated by one instrument for
the return generated by another instrument. The Fund may enter into swap
agreements to manage its exposure to interest rates and/or credit risk or to
generate income. Interest rate swap agreements involve the exchange by the Fund
with another party of their respective commitments to pay or receive interest.
Total return swap agreements involve commitments to receive (and pay) interest
over a floating rate (LIBOR) based on a notional amount. To the extent the total
return of the security (price changes, interest paid/received, rebate earned on
collateral posted by the Fund) is positive, the Fund will receive a payment from
the counterparty (or if negative, make a payment to the counterparty). The swaps
are valued daily at current market value and any unrealized gain or loss is
included in the Statement of Assets and Liabilities. Gain or loss is realized on
the termination date of the swap and is equal to the difference between the
Fund's basis in the swap and the proceeds of the closing transaction, including
any fees. During the period that the swap agreement is open, the Fund may be
subject to risk from the potential inability of the counterparty to meet the
terms of the agreement. The swaps involve

elements of both market and credit risk in excess of the amounts reflected on
the Statement of Assets and Liabilities. Upon termination of a swap agreement, a
payable to or receivable from swap counterparty is established on the Statement
of Assets and Liabilities to reflect the net gain/loss, including interest
income/expense, on terminated swap positions. This line item is removed upon
settlement according to the terms of the swap agreement.

Realized gain (loss) upon termination of swap contracts is recorded on the
Statement of Operations. Fluctuations in the value of swap contracts are
recorded as a component of net change in unrealized appreciation (depreciation)
of swap contracts. Net periodic payments received by the Fund are included as
part of realized gains (losses) and, in the case of accruals for periodic
payments, are included as part of unrealized appreciation (depreciation) on the
Statement of Operations.

(E) SECURITIES LENDING

The Fund may lend its securities to broker-dealers and financial institutions.
The loans are collateralized by cash or securities at least equal at all times
to the market value of the securities loaned. The Fund may bear the risk of
delay in recovery of, or loss of rights in, the securities loaned should the
borrower of the securities experience financial difficulty. The Fund receives
compensation for lending its securities in the form of fees or it retains a
portion of interest on the investment of any cash received as collateral. The
Fund also continues to receive interest and dividends on the securities loaned,
and any gain or loss in the market price of the securities loaned that may occur
during the term of the loan will be for the account of the Fund. During the year
ended October 31, 2008, the Fund maintained a securities lending agreement with
Lehman Brothers acting as the counterparty. Pursuant to the lending agreement,
the Fund had the right to sell or repledge the collateral received, U.S.
Treasury Bonds from Lehman Brothers, in the case of default. On September 25,
2008 the outstanding securities on loan were removed from the portfolio, and the
collateral received was sold resulting in a loss of $59,023. As of October 31,
2008, the Fund had no securities on loan.

(F) 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.

(G) DISTRIBUTIONS TO SHAREHOLDERS

The Fund declares and pays monthly dividends to common shareholders. These
dividends consist of investment company taxable income, which generally includes
qualified dividend income, ordinary income and short-term capital gains. Any net
realized long-term gains are distributed annually to common shareholders.

Distributions to shareholders are recorded on the ex-dividend date. The amount
and timing of distributions are determined in accordance with federal income tax
regulations, which may differ from U.S. generally accepted accounting
principles.


Note 3 - INVESTMENT MANAGEMENT AGREEMENT, SERVICING AGREEMENT AND OTHER
AGREEMENTS:

Pursuant to the Investment Management Agreement (the "Agreement") between the
Fund and Advent Capital Management, LLC, the Fund's investment adviser (the
"Advisor"), the Advisor 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 Advisor will receive an annual fee
from the Fund based on the average value of the Fund's Managed Assets, which
includes the amount from the issuance of the Preferred Shares. 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
Advisor who devote substantial time to Fund operations may be reimbursed by the
Fund to the Advisor. For the year ended October 31, 2008, the Advisor 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. In addition, the Advisor
     has agreed to waive receipt of a portion of the management fee or other
     expenses of the Fund in the amount of 0.115% of the average value of the
     Managed Assets for the first five years of the Fund's operations ending
     April 30, 2008. Effective May 1, 2008, the Advisor is waiving receipt of a
     portion of the management fee or other expenses of the Fund in the amount
     of 0.065% of the average value of the Managed Assets for an additional one
     year. For the year ended October 31, 2008, the Advisor waived advisory fees
     of $751,429.

Pursuant to a Servicing Agreement between the Fund and Claymore Securities,
Inc., the Fund's servicing agent (the "Servicing Agent"), the Servicing Agent
will act as servicing agent to the Fund. The Servicing Agent will receive an
annual fee from the Fund, which will be based on the average value of the Fund's
Managed Assets. The fee will be determined as follows:

(a)  If the average value of the Fund's Managed Assets (calculated monthly) is
     greater than $250 million, the fee will be a maximum amount equal to 0.21%
     of the average value of the Fund's Managed Assets. In addition, the
     Servicing Agent has agreed to waive receipt of a portion of the servicing
     fee of the Fund in the amount of 0.085% of the average value of the Managed
     Assets for the first five years of the Fund's operations ending April 30,
     2008. Effective May 1, 2008, the Servicing Agent is waiving receipt of a
     portion of the servicing fee of the Fund in the amount of 0.065% of the
     average value of the Managed Assets for an additional one year. For the
     year ended October 31, 2008, the Servicing Agent waived fees of $621,626.

The fee waivers of the Advisor and the Servicing Agent are contractual
commitments of more than one year and are not subject to recoupment.

The Bank of New York Mellon ("BNY") acts as the Fund's custodian, accounting
agent, auction agent and transfer agent. As custodian, BNY is responsible for
the custody of the Fund's assets. As accounting agent, BNY is responsible for
maintaining the books and records of the Fund's securities and cash. As auction
agent, BNY is responsible for conducting the auction of the preferred shares. As
transfer agent, BNY is responsible for performing transfer agency services for
the Fund.

Prior to May 1, 2008, BNY provided Fund Administration services to the Fund.
Effective May 1, 2008, Claymore Advisors, LLC began providing Fund
Administration services to the Fund. As compensation for its services performed
under the Administration Agreement, Claymore Advisors, LLC receives an
administration fee payable monthly at the annual rate set forth below as a
percentage of the average daily managed assets of the Fund:

MANAGED  ASSETS                                             RATE

Certain officers and trustees of the Fund are also officers and directors of the
Advisor 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 can
avoid a 4% federal excise tax that is assessed on the amount of the
under-distribution. For the 2007 calendar year, the Fund was under distributed
for excise tax purposes. Therefore, the Fund was subject to a 4% excise tax
totaling $107,961. This amount was initially paid by Claymore Advisors, LLC, an
affiliate of the Fund, and will be reimbursed by the Fund.

In order to present paid-in capital in excess of par and accumulated net
realized gains or losses on the Statement of Assets and Liabilities that more
closely represent their tax character, certain adjustments have been made to
undistributed net investment income and accumulated net realized gains or losses
on investments. For the year ended October 31, 2008, the adjustments were to
decrease accumulated net realized gain on investments by $16,693,832, decrease
paid-in capital by $107,961 and increase undistributed net investment income by
$16,801,793 due to the difference in the treatment for book and tax purposes of
Canadian income trusts, publicly traded partnerships, trust preferreds,
distribution reclass, convertible bonds, contingent payment debt instruments,
swaps, and foreign currency.

----------------------------------------------------------------

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

At October 31, 2008, for federal income tax purposes, the Fund had a capital
loss carryforward of $96,787,165 available to offset possible future capital
gains. The capital loss carryforward is set to expire on October 31, 2016.

For the years ended October 31, 2008 and October 31, 2007, the tax character of
distributions paid of $54,863,421 and $53,996,821 was ordinary income,
$8,493,296 and $21,390,145 was long-term capital gain, and $363,640 and $0 was
return of capital, respectively.

On July 13, 2006, the Financial Accounting Standards Board ("FASB") released
FASB Interpretation No. 48, "Accounting for Uncertainty in Income Taxes" ("FIN
48"). FIN 48 provides guidance for how uncertain tax positions should be
recognized, measured, presented and disclosed in the financial statements. FIN
48 requires the evaluation of tax positions taken or expected to be taken in the
course of preparing the Fund's tax returns to determine whether the tax
positions are "more-likely-than-not" of being sustained by the applicable tax
authority. Tax positions not deemed to meet the more-likely-than-not threshold
would be recorded as a tax expense in the current year. Management has evaluated
the implication of FIN 48 and has determined it does not have any impact on the
financial statements as of October 31, 2008. There is no tax liability resulting
from unrecognized tax benefits relating to uncertain income tax positions taken
or expected to be taken on the tax return for the fiscal year-end October 31,
2008. 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 twelve months.

FIN 48 requires the Fund to analyze all open tax years. Open tax years are those
years that are open for examination by the relevant income taxing authority. As
of October 31, 2008, open Federal and state income tax years include the tax
years ended October 31, 2004, 2005, 2006 and 2007. The Fund has no examination
in progress.


Note 5 - INVESTMENTS IN SECURITIES AND SWAPS:
For the year ended October 31, 2008, purchases and sales of investments, other
than short-term securities, were $687,542,570 and $750,380,232, respectively.

The Fund entered into total return and credit default swap agreements during the
year ended October 31, 2008 to generate additional income. As of October 31,
2008, the Fund had swaps with a total notional value of $24,804,168 outstanding.

For each swap noted, the Fund pays a floating rate and receives the total return
of the underlying asset, which includes receiving a floating interest rate
component. The market value of the swaps outstanding reflects the current
receivable and payable for the underlying asset, including the total return and
the interest rate component, which may have different payment dates.


Note 6 - CAPITAL:

COMMON SHARES

The Fund has an unlimited amount of common shares, $0.001 par value, authorized
and 23,562,858 issued and outstanding. In connection with the Fund's dividend
reinvestment plan, the Fund issued 31,536 shares during the year ended October
31, 2008, and 141,118 shares during the year ended October 31, 2007. At October
31, 2008, Advent Capital Management LLC, the Fund's investment adviser, owned
6,924 shares of the Fund.

PREFERRED SHARES

On June 19, 2003, the Fund's Board of Trustees authorized the issuance of
Auction Market Preferred Shares ("AMPS"), as part of the Fund's leverage
strategy. AMPS issued by the Fund have seniority over the common shares.

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

Dividends are accumulated daily at a rate set through an auction process. The
broad auction-rate preferred securities market, including the Fund's AMPS, has
experienced considerable disruption since mid-February, 2008. The result has
been failed auctions on nearly all auction-rate preferred shares, including the
Fund's AMPS. A failed auction is not a default, nor does it require the
redemption of the Fund's AMPS.

Provisions in the AMPS offering documents establish a maximum rate in the event
of a failed auction. The AMPS reference rate is the LIBOR Rate for a dividend
period of fewer than 365 days. The maximum rate, for auctions for which the Fund
has not given notice that the auction will consist of net capital gains or other
taxable income, is the higher of the reference rate times 125% or the reference
rate plus 1.25%. Distributions of net realized gains, if any, are made annually.

Management will continue to monitor events in the marketplace and continue to
evaluate the Fund's leverage as well as any alternative that may be available.

For the year ended October 31, 2008, the annualized dividend rates ranged from:

                    HIGH              LOW        AT OCTOBER 31, 2008
--------------------------------------------------------------------
Series M7           5.94%            3.39%                      3.39%
Series T28          6.19             3.70                       4.78
Series W7           5.77             3.27                       3.27
Series W28          5.65             3.65                       5.54
Series TH28         5.76             3.64                       5.76
Series F7           5.94             3.41                       3.41

The Fund is subject to certain limitations and restrictions while Preferred
Shares are outstanding. Failure to comply with these limitations and
restrictions could preclude the Fund from declaring any dividends or
distributions to common shareholders or repurchasing common shares and/or could
trigger the mandatory redemption of Preferred Shares at their liquidation value.

Preferred Shares, which are entitled to one vote per share, generally vote with
the common stock but vote separately as a class to elect two Trustees and on any
matters affecting the rights of the Preferred Shares.


Note 8 - INDEMNIFICATIONS:

In the normal course of business, the Fund enters into contracts that contain a
variety of representations, which provide general indemnifications. The Fund's
maximum exposure under these arrangements is unknown, as this would involve
future claims that may be made against the Fund that have not yet occurred.
However, the Fund expects the risk of loss to be remote.

Note 10 - ACCOUNTING PRONOUNCEMENTS:

In September 2006, the FASB released Statement of Financial Accounting Standards
("SFAS") No. 157, "Fair Value Measurements" ("FAS 157"). This standard clarifies
the definition of fair value for financial reporting, establishes a framework
for measuring fair value and requires additional disclosures about the use of
fair value measurements. FAS 157 is effective for financial statements issued
for fiscal years beginning after November 15, 2007 and interim periods within
those fiscal years. As of October 31, 2008, the Fund does not believe the
adoption of FAS 157 will impact the amounts reported in the financial
statements, however, additional disclosure will be required about the inputs
used to develop measurements of fair value and the effect of certain of the
measurements reported in the statement of operations for a fiscal period.

In March 2008, the FASB issued SFAS No. 161, "Disclosures about Derivative
Instruments and Hedging Activities." This standard is intended to enhance
financial statement disclosures for derivative instruments and hedging
activities and enable investors to understand: a) how and why a fund uses
derivative instruments, b) how derivatives instruments and related hedge fund
items are accounted for, and c) how derivative instruments and related hedge
items affect a fund's financial position, results of operations and cash flows.
SFAS No. 161 is effective for financial statements issued for fiscal years and
interim periods beginning after November 15, 2008. In September 2008, the FASB
issued a Staff Position amending SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities." This amendment would require disclosures by
sellers of credit derivatives, including credit derivatives embedded in a hybrid
instrument. This amendment is effective for financial statements issued for
fiscal years and interim periods ending after November 15, 2008. As of October
31, 2008, management does not believe the adoption of SFAS No. 161 nor amended
SFAS No. 133 will impact the financial statement amounts; however, additional
footnote disclosures may be required about the use of derivative instruments and
hedging items.

AVK | Advent Claymore Convertible Securities and Income Fund

Report of INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM|



TO THE BOARD OF TRUSTEES AND SHAREHOLDERS OF
ADVENT CLAYMORE CONVERTIBLE SECURITIES AND INCOME FUND:

In our opinion, the accompanying statement of assets and liabilities, including
the portfolio of investments, and the related statements of operations and of
changes in net assets applicable to common shareholders and the financial
highlights present fairly, in all material respects, the financial position of
the Advent Claymore Convertible Securities and Income Fund (the "Fund") at
October 31, 2008, the results of its operations for the year then ended, the
changes in its net assets applicable to common shareholders for each of the two
years in the period then ended and the financial highlights for each of the
periods presented, in conformity with accounting principles generally accepted
in the United States of America. These financial statements and financial
highlights (hereafter referred to as "financial statements") are the
responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these financial statements in accordance with the standards of the
Public Company Accounting Oversight Board (United States). Those standards
require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement. An audit
includes examining on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits, which included
confirmation of securities at October 31, 2008 by correspondence with the
custodian and brokers, provide a reasonable basis for our opinion.

Dividend Reinvestment PLAN| (unaudited)

Unless the registered owner of common shares elects to receive cash by
contacting the Plan Administrator, all dividends declared on common shares of
the Fund will be automatically reinvested by The Bank of New York Mellon (the
"Plan Administrator"), Administrator for shareholders in the Fund's Dividend
Reinvestment Plan (the "Plan"), in additional common shares of the Fund.
Participation in the Plan is completely voluntary and may be terminated or
resumed at any time without penalty by notice if received and processed by the
Plan Administrator prior to the dividend record date; otherwise such termination
or resumption will be effective with respect to any subsequently declared
dividend or other distribution. Some brokers may automatically elect to receive
cash on your behalf and may re-invest that cash in additional common shares of
the Fund for you. If you wish for all dividends declared on your common shares
of the Fund to be automatically reinvested pursuant to the Plan, please contact
your broker.

The Plan Administrator will open an account for each common shareholder under
the Plan in the same name in which such common shareholder's common shares are
registered. Whenever the Fund declares a dividend or other distribution
(together, a "Dividend") payable in cash, non-participants in the Plan will
receive cash and participants in the Plan will receive the equivalent in common
shares. The common shares will be acquired by the Plan Administrator for the
participants' accounts, depending upon the circumstances described below, either
(i) through receipt of additional unissued but authorized common shares from the
Fund ("Newly Issued Common Shares") or (ii) by purchase of outstanding common
shares on the open market ("Open-Market Purchases") on the New York Stock
Exchange or elsewhere. If, on the payment date for any Dividend, the closing
market price plus estimated brokerage commission per common share is equal to or
greater than the net asset value per common share, the Plan Administrator will
invest the Dividend amount in Newly Issued Common Shares on behalf of the
participants. The number of Newly Issued Common Shares to be credited to each
participant's account will be determined by dividing the dollar amount of the
Dividend by the net asset value per common share on the payment date; provided
that, if the net asset value is less than or equal to 95% of the closing market
value on the payment date, the dollar amount of the Dividend will be divided by
95% of the closing market price per common share on the payment date. If, on the
payment date for any Dividend, the net asset value per common share is greater
than the closing market value plus estimated brokerage commission, the Plan
Administrator will invest the Dividend amount in common shares acquired on
behalf of the participants in Open-Market Purchases.

If, before the Plan Administrator has completed its Open-Market Purchases, the
market price per common share exceeds the net asset value per common share, the
average per common share purchase price paid by the Plan Administrator may
exceed the net asset value of the common shares, resulting in the acquisition of
fewer common shares than if the Dividend had been paid in Newly Issued Common
Shares on the Dividend payment date. Because of the foregoing difficulty with
respect to Open-Market Purchases, the Plan provides that if the Plan
Administrator is unable to invest the full Dividend amount in Open-Market
Purchases during the purchase period or if the market discount shifts to a
market premium during the purchase period, the Plan Administrator may cease
making Open-Market Purchases and may invest the uninvested portion of the
Dividend amount in Newly Issued Common Shares at net asset value per common
share at the close of business on the Last Purchase Date provided that, if the
net asset value is less than or equal to 95% of the then current market price
per common share; the dollar amount of the Dividend will be divided by 95% of
the market price on the payment date.

The Plan Administrator maintains all shareholders' accounts in the Plan and
furnishes written confirmation of all transactions in the accounts, including
information needed by shareholders for tax records. Common shares in the account
of each Plan participant will be held by the Plan Administrator on behalf of the
Plan participant, and each shareholder proxy will include those shares purchased
or received pursuant to the Plan. The Plan Administrator will forward all proxy
solicitation materials to participants and vote proxies for shares held under
the Plan in accordance with the instruction of the participants.

There will be no brokerage charges with respect to common shares issued directly
by the Fund. However, each participant will pay a pro rata share of brokerage
commission incurred in connection with Open-Market Purchases. The automatic
reinvestment of Dividends will not relieve participants of any Federal, state or
local income tax that may be payable (or required to be withheld) on such
Dividends.

The Fund reserves the right to amend or terminate the Plan. There is no direct
service charge to participants with regard to purchases in the Plan; however,
the Fund reserves the right to amend the Plan to include a service charge
payable by the participants.

All correspondence or questions concerning the Plan should be directed to the
Plan Administrator, The Bank of New York Mellon, Attention: Stock Transfer
Department, 101 Barclay 11E, New York, NY 10286, Phone Number: (866) 488-3559.

     principal accounting officer or controller, or persons performing similar
     functions.

committee financial experts serving on its audit committee, each of whom is an
"independent" Trustee: Randall C. Barnes, Daniel Black, Derek Medina, Ronald

Mr. Barnes qualifies as an audit committee financial expert by virtue of his
experience obtained as a former Senior Vice President, Treasurer of PepsiCo,
Inc.

experience obtained as a partner of a private equity firm, which includes review
and analysis of audited and unaudited financial statements using GAAP to show
accounting estimates, accruals and reserves.

Mr. Medina qualifies as an audit committee financial expert by virtue of his
experience obtained as a Senior Vice President, Business Affairs of ABC News and
as a former associate in Corporate Finance at J.P. Morgan/Morgan Guaranty, which
includes review and analysis of audited and unaudited financial statements using
GAAP to show accounting estimates, accruals and reserves.

Mr. Nyberg qualifies as an audit committee financial expert by virtue of his

Act of 1933, as a result of being designated or identified as an audit committee
financial expert. The designation or identification of a person as an audit
committee financial expert does not impose on such person any duties,
obligations, or liabilities that are greater than the duties, obligations, and
liabilities imposed on such person as a member of the audit committee and Board
of Trustees in the absence of such designation or identification. The
designation or identification of a person as an audit committee financial expert

                                    2007: $82,450



(b)  Audit-Related Fees: the aggregate fees billed in each of the last two
     fiscal years for assurance and related services by the principal accountant
     that are reasonably related to the performance of the audit of the
     registrant's financial statements and are not reported under paragraph (a)
     of this item are as follows:

                                    2008: $16,700

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

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

          The Trust's Audit Committee has adopted written policies relating to
          the pre-approval of the audit and non-audit services performed by the
          Trust'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 Trust's Audit Committee reviews and
          pre-approves the services to be provided by the independent auditors
          without having obtained 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 Trust.


                     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)(i)(C) of
          Rule 2-01 of Regulation S-X.

(f)  The aggregate non-audit fees billed for the last two fiscal years by the
     registrant's accountant for services rendered to the registrant, the
     registrant's investment adviser, and any entity controlling, controlled by,
     or under common control with the adviser that provides ongoing services to
     the registrant (not including a sub-adviser whose role is primarily
     portfolio management and is subcontracted with or overseen by another
     investment adviser) that directly related to the operations and financial
     reporting of the registrant are as follows:

                                    2008: $55,000
                                    2007: $30,067

(g)  Not applicable.



ITEM 5. AUDIT COMMITTEE OF LISTED REGISTRANTS.

(a) The registrant has a separately designated standing audit committee
established in accordance with Section 3(a)(58)(A) of the Securities Exchange
Act of 1934. The audit committee of the registrant is comprised of: Randall C.
Barnes, Daniel Black, Derek Medina, Ronald Nyberg, Gerald L. Seizert and Michael
A. Smart.

(b) Not applicable.

ITEM 6. SCHEDULE OF INVESTMENTS.

The Schedule of Investments is included as part of Item 1.

ITEM 7. DISCLOSURE OF PROXY VOTING POLICIES AND PROCEDURES FOR CLOSED-END

securities to its investment advisor, Advent Capital Management, LLC (the
"Advisor"). The Advisor's Proxy Voting Policies and Procedures are included as
an exhibit hereto.

ITEM 8. PORTFOLIO MANAGERS OF CLOSED-END MANAGEMENT INVESTMENT COMPANIES.
