MuniYield California Insured Fund, Inc.

The Benefits and Risks of Leveraging

MuniYield California Insured Fund, Inc. utilizes leveraging to seek to enhance
the yield and net asset value of its Common Stock. However, these objectives
cannot be achieved in all interest rate environments. To leverage, the Fund
issues Preferred Stock, which pays dividends at prevailing short-term interest
rates, and invests the proceeds in long-term municipal bonds. The interest
earned on these investments, net of dividends to Preferred Stock, is paid to
Common Stock shareholders in the form of dividends, and the value of these
portfolio holdings is reflected in the per share net asset value of the Fund's
Common Stock. However, in order to benefit Common Stock shareholders, the yield
curve must be positively sloped; that is, short-term interest rates must be
lower than long-term interest rates. At the same time, a period of generally
declining interest rates will benefit Common Stock shareholders. If either of
these conditions change, then the risks of leveraging will begin to outweigh the
benefits.

To illustrate these concepts, assume a fund's Common Stock capitalization of
$100 million and the issuance of Preferred Stock for an additional $50 million,
creating a total value of $150 million available for investment in long-term
municipal bonds. If prevailing short-term interest rates are approximately 3%
and long-term interest rates are approximately 6%, the yield curve has a
strongly positive slope. The fund pays dividends on the $50 million of Preferred
Stock based on the lower short-term interest rates. At the same time, the fund's
total portfolio of $150 million earns the income based on long-term interest
rates. Of course, increases in short-term interest rates would reduce (and even
eliminate) the dividends on the Common Stock.

In this case, the dividends paid to Preferred Stock shareholders are
significantly lower than the income earned on the fund's long-term investments,
and therefore the Common Stock shareholders are the beneficiaries of the
incremental yield. However, if short-term interest rates rise, narrowing the
differential between short-term and long-term interest rates, the incremental
yield pickup on the Common Stock will be reduced or eliminated completely. At
the same time, the market value of the fund's Common Stock (that is, its price
as listed on the New York Stock Exchange) may, as a result, decline.
Furthermore, if long-term interest rates rise, the Common Stock's net asset
value will reflect the full decline in the price of the portfolio's investments,
since the value of the fund's Preferred Stock does not fluctuate. In addition to
the decline in net asset value, the market value of the fund's Common Stock may
also decline.

As a part of its investment strategy, the Fund may invest in certain securities
whose potential income return is inversely related to changes in a floating
interest rate ("inverse floaters"). In general, income on inverse floaters will
decrease when short-term interest rates increase and increase when short-term
interest rates decrease. Investments in inverse floaters may be characterized as
derivative securities and may subject the Fund to the risks of reduced or
eliminated interest payments and losses of invested principal. In addition,
inverse floaters have the effect of providing investment leverage and, as a
result, the market value of such securities will generally be more volatile than
that of fixed-rate, tax-exempt securities. To the extent the Fund invests in
inverse floaters, the market value of the Fund's portfolio and the net asset
value of the Fund's shares may also be more volatile than if the Fund did not
invest in these securities. As of October 31, 2003, the percentage of the Fund's
total net assets invested in inverse floaters was 10.03%.

Swap Agreements

The Fund may also invest in swap agreements, which are over-the-counter
contracts in which one party agrees to make periodic payments based on the
change in market value of a specified bond, basket of bonds, or index in return
for periodic payments based on a fixed or variable interest rate or the change
in market value of a different bond, basket of bonds or index. Swap agreements
may be used to obtain exposure to a bond or market without owning or taking
physical custody of securities.

A Letter From the President

Dear Shareholder

As 2003 draws to a close, it seems appropriate to reflect on what has been a
meaningful year in many respects. We saw the beginning and the end of all-out
war in Iraq, equity market uncertainty turned to strength and sub par gross
domestic product growth of 1.4% in the first quarter of 2003 grew to an
extraordinary 8.2% in the third quarter. Amid the good news, fixed income
investments, which had become the asset class of choice during the preceding
three-year equity market decline, faced new challenges.

During 2003, municipal bond yields rose and fell in reaction to geopolitical
events, equity market performance, economic activity and employment figures. By
the end of October, long-term municipal revenue bond yields were slightly higher
than they were one year earlier, at 5.24% as measured by the Bond Buyer Revenue
Bond Index. With many state deficits at record levels, municipalities issued
nearly $400 billion in new long-term tax-exempt bonds during the 12-month period
ended October 31, 2003. The availability of bonds, together with attractive
yield ratios relative to U.S. Treasury issues, made municipal bonds a popular
fixed income investment alternative.

Throughout the year, our portfolio managers continued to work diligently to
deliver on our commitment to provide superior performance within reasonable
expectations for risk and return. This included striving to outperform our peers
and the market indexes. With that said, remember that the advice and guidance of
a skilled financial advisor often can mean the difference between successful and
unsuccessful investing. A financial professional can help you choose those
investments that will best serve you as you plan for your financial future.

Finally, I am proud to premiere a new look to our shareholder communications.
Our portfolio manager commentaries have been trimmed and organized in such a way
that you can get the information you need at a glance, in plain language.
Today's markets are confusing enough. We want to help you put it all in
perspective. The report's new size also allows us certain mailing efficiencies.
Any cost savings in production or postage are passed on to the Fund and,
ultimately, to Fund shareholders.

We thank you for trusting Merrill Lynch Investment Managers with your investment
assets, and we look forward to serving you in the months and years ahead.

                                                Sincerely,


                                                /s/ Terry K. Glenn

                                                Terry K. Glenn

A Discussion With Your Fund's Portfolio Manager

      In a very volatile period for interest rates, we maintained our focus on
enhancing the credit quality of the portfolio while protecting the Fund from net
asset value volatility.

Describe the market environment relative to municipal bonds during the fiscal
year.

At the end of October, long-term tax-exempt bond yields were 90% - 95% of
comparable U.S. Treasury securities, substantially exceeding their historical
average of 85% - 88%. Considering their tax-free status, this made long-term
municipal bonds an attractive investment alternative during the past 12 months.

Long-term U.S. Treasury bond yields declined throughout most of the first seven
months of the fiscal year, while bond prices -- which move in the opposite
direction of yields -- rose in response to weak equity markets, concerns about a
growing conflict in Iraq and continued sub par U.S. economic growth. The Federal
Reserve Board continued to lower short-term interest rates to stimulate business
and consumer economic activity. Bond yields reversed course in July and August,
rising sharply as economic conditions began to improve and as most analysts
agreed the Federal Reserve Board had finished lowering interest rates. In
mid-August, U.S. Treasury bond yields reached 5.45%, their highest level during
the period, before again moving lower for the remainder of the fiscal year. At
the end of the 12-month period, long-term U.S. Treasury bond yields were 5.13%,
15 basis points (.15%) higher than a year earlier. The relatively modest yield
increase year-over-year masks the considerable month-to-month volatility in
interest rates during the period.

Long-term tax-exempt bond yields also rose from year-ago levels, although to a
lesser extent than U.S. Treasury bonds. Yield movements were less volatile than
those experienced by U.S. Treasury issues, because municipal bond prices
typically are less sensitive to short-term economic and geopolitical pressures.
By the end of October, long-term municipal revenue bond yields stood at 5.24%, a
small increase compared to the previous year. Yields for long-term Aaa-rated
tax-exempt bonds (the highest rated) declined 10 basis points during the past
year. The decline largely reflected investors' growing demand for high-quality
bonds, which provided valuable stability in an uncertain market.

The municipal market's outperformance of the U.S. Treasury market was especially
impressive given the dramatic increase in new bond issuance during the fiscal
year. State and local governments took advantage of historically low interest
rates to finance existing infrastructure needs and refinance outstanding
high-interest-rate debt. During the past 12 months, municipalities issued nearly
$400 billion in new securities, an increase of more than 12% compared to last
year's issuance. More recently, however, new municipal bond issuance slowed as
tax-exempt bond yields rose, making borrowing more expensive. Less than $90
billion in long-term tax-exempt bonds was underwritten during the period's last
three months, a decline of nearly 10% versus the same three months of 2002. This
decline in supply helped support the tax-exempt market's recent performance.

Describe conditions in the state of California during the period.

In July 2003, Standard & Poor's downgraded California's credit rating to BBB,
the lowest of any state in the nation. The credit downgrade stemmed from
uncertainty about California's financial situation, characterized by a deficit
that then exceeded $38 billion. Since that time, the state managed to pass a
budget. Unfortunately for California's finances, the budget included record
amounts of new borrowing and lacked provisions to significantly cut government
spending or increase tax revenues. To close its budget gap, California plans to
issue new general obligation debt, quasi-state-backed bonds secured by a legal
settlement with the tobacco industry, and "fiscal recovery" bonds to refinance
California's high-interest-rate debt. Some of these bond issues, however, are
likely to face legal challenges.

California's political situation was clarified in October, when Arnold
Schwarzenegger won a recall election to succeed Gray Davis as governor. It is,
however, unclear whether this election will lead to significant changes in the
state's fiscal responsibility or in its financial condition.

California general debt obligations offered as much as 75 basis points of
additional yield relative to comparable AAA-rated municipal bonds during the
period, reflecting investors' concern about the state's credit problems. As the
period progressed, that spread narrowed to 35 basis points before widening to 50
basis points late in the period. The more recent wider spreads were prompted by
renewed skepticism following the recall and anticipated new bond supply.

How did the Fund perform during the period in light of the existing market
conditions?

For the year ended October 31, 2003, the Common Stock of MuniYield California
Insured Fund, Inc. had a net annualized


4       MUNIYIELD CALIFORNIA INSURED FUND, INC.     OCTOBER 31, 2003


yield of 5.76%, based on a year-end per share net asset value of $15.10 and
$.870 per share income dividends. Over the same period, the total investment
return on the Fund's Common Stock was +5.29%, based on a change in per share net
asset value from $15.26 to $15.10, and assuming reinvestment of $.867 per share
ordinary income dividends.

For the six-month period ended October 31, 2003, the total investment return on
the Fund's Common Stock was +.44%, based on a change in per share net asset
value from $15.51 to $15.10 and assuming reinvestment of $.438 per share
ordinary income dividends.

For the six-month period ended October 31, 2003, the Fund's Auction Market
Preferred Stock had average yields as follows: .88% for Series A; .74% for
Series B; .68% for Series C; .78% for Series D; and .69% for Series E.

For a description of the Fund's total investment return based on a change in the
per share market value of the Fund's Common Stock (as measured by the trading
price of the Fund's shares on the New York Stock Exchange), and assuming
reinvestment of dividends, please refer to the Financial Highlights section of
the Financial Statements included in this report. As a closed-end fund, the
Fund's shares may trade in the secondary market at a premium or discount to the
Fund's net asset value. As a result, total investment returns based on changes
in the market value of the Fund's Common Stock can vary significantly from total
investment return based on changes in the Fund's net asset value.

The Fund's total return performance, based on net asset value, trailed that of
its comparable Lipper category of California Insured Municipal Debt Funds, which
had an average return of +5.5% for the same 12-month period. In terms of yield,
we intend to restructure the portfolio to improve our competitive position. We
believe this is best accomplished after interest rates rise, which should allow
us to create a portfolio with a higher-than-average coupon structure. Until
then, we remain focused on protecting the Fund's net asset value by maintaining
a defensive market stance with a low duration asset mix.

What changes were made to the portfolio during the period?

We made few significant changes to the portfolio during the fiscal year. We
continued to adopt a defensive portfolio structure, with approximately 85% of
the Fund invested in insured California bonds on October 31, 2003 --
consistently above the Fund's mandated limit of 80%. We also raised the average
couponing of the Fund's holdings during the period and concentrated assets in
parts of the yield curve that we believe offer the best value for the level of
interest rate risk taken.

As mentioned earlier, we sought to restructure the portfolio to generate higher
average coupon payments from the Fund's holdings, but believe this would be most
advantageous in a higher-interest-rate environment. In the meantime, we focused
on seeking to protect the Fund's net asset value through our defensive approach,
which also included keeping the Fund's duration -- its sensitivity to interest
rates -- relatively low. Another defensive action was to use interest rate swaps
in an effort to cushion the Fund from the negative effects that an interest rate
increase would have on bond prices.

In terms of leverage, the Fund's borrowing costs remained between .75% - 1.25%
during the fiscal year. These attractive funding levels, in combination with a
steep tax-exempt yield curve, generated a significant income benefit to the
Fund's Common Stock shareholders. Further declines in the Fund's borrowing costs
would require significant easing of monetary policy by the Federal Reserve
Board. While such action is not expected, neither is an imminent increase in
short-term interest rates. We expect short-term borrowing costs to remain near
current attractive levels for the coming months. However, should the spread
between short-term and long-term interest rates narrow, the benefits of leverage
will decline, and as a result, reduce the yield on the Fund's Common Stock. (For
a more complete explanation of the benefits and risks of leveraging, see page 2
of this report to shareholders.)

How would you characterize the portfolio's position at the close of the period?

We continued to position the portfolio defensively, keeping its duration shorter
than our Lipper group. Our focus is on maintaining the Fund's net asset value,
as we anticipate continued interest rate volatility. We believe the Fund's
defensive structure should mute some of the price volatility that may result if
long-term market rates continue to rise.

Notes to Financial Statements

1. Significant Accounting Policies:

MuniYield California Insured Fund, Inc. (the "Fund") is registered under the
Investment Company Act of 1940, as amended, as a non-diversified, closed-end
management investment company. The Fund's financial statements are prepared in
conformity with accounting principles generally accepted in the United States of
America, which may require the use of management accruals and estimates. The
Fund determines and makes available for publication the net asset value of its
Common Stock on a weekly basis. The Fund's Common Stock is listed on the New
York Stock Exchange under the symbol MCA. The following is a summary of
significant accounting policies followed by the Fund.

(a) Valuation of investments -- Municipal bonds are traded primarily in the
over-the-counter markets and are valued at the last available bid price in the
over-the-counter market or on the basis of yield equivalents as obtained by the
Fund's pricing service from one or more dealers that make markets in such
securities. Financial futures contracts and options thereon, which are traded on
exchanges, are valued at their closing prices as of the close of such exchanges.
Options written or purchased are valued at the last sale price in the case of
exchange-traded options. In the case of options traded in the over-the-counter
market, valuation is the last asked price (options written) or the last bid
price (options purchased). Swap agreements are valued by quoted fair values
received daily by the Fund from the counterparty. Short-term securities with a
remaining maturity of sixty days or less are valued at amortized cost, which
approximates market value. Securities and assets for which market quotations are
not readily available are valued at fair value as determined in good faith by or
under the direction of the Board of Directors of the Fund, including valuations
furnished by a pricing service retained by the Fund, which may utilize a matrix
system for valuations. The procedures of the pricing service and its valuations
are reviewed by the officers of the Fund under the general supervision of the
Board of Directors.

b) Derivative financial instruments -- The Fund may engage in various portfolio
investment strategies both to increase the return of the Fund and to hedge, or
protect, its exposure to interest rate movements and movements in the securities
markets. Losses may arise due to changes in the value of the contract or if the
counterparty does not perform under the contract.

o     Financial futures contracts -- The Fund may purchase or sell financial
      futures contracts and options on such futures contracts. Futures contracts
      are contracts for delayed delivery of securities at a specific future date
      and at a specific price or yield. Upon entering into a contract, the Fund
      deposits and maintains as collateral such initial margin as required by
      the exchange on which the transaction is effected. Pursuant to the
      contract, the Fund agrees to receive from or pay to the broker an amount
      of cash equal to the daily fluctuation in value of the contract. Such
      receipts or payments are known as variation margin and are recorded by the
      Fund as unrealized gains or losses. When the contract is closed, the Fund
      records a realized gain or loss equal to the difference between the value
      of the contract at the time it was opened and the value at the time it was
      closed.

o     Options -- The Fund is authorized to write covered call options and
      purchase put options. When the Fund writes an option, an amount equal to
      the premium received by the Fund is reflected as an asset and an
      equivalent liability. The amount of the liability is subsequently marked
      to market to reflect the current market value of the option written. When
      a security is purchased or sold through an exercise of an option, the
      related premium paid (or received) is added to (or deducted from) the
      basis of the security acquired or deducted from (or added to) the proceeds
      of the security sold. When an option expires (or the Fund enters into a
      closing transaction), the Fund realizes a gain or loss on the option to
      the extent of the premiums received or paid (or gain or loss to the extent
      the cost of the closing transaction exceeds the premium paid or received).


16       MUNIYIELD CALIFORNIA INSURED FUND, INC.     OCTOBER 31, 2003


Notes to Financial Statements (continued)

      Written and purchased options are non-income producing investments.

o     Forward interest rate swaps -- The Fund may enter into forward interest
      rate swaps. In a forward interest rate swap, the Fund and the counterparty
      agree to make periodic net payments on a specified notional contract
      amount, commencing on a specified future effective date, unless terminated
      earlier. When the agreement is closed, the Fund records a realized gain or
      loss in an amount equal to the value of the agreement.

(c) Income taxes -- It is the Fund's policy to comply with the requirements of
the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income to its shareholders.
Therefore, no Federal income tax provision is required.

(d) Security transactions and investment income -- Security transactions are
recorded on the dates the transactions are entered into (the trade dates).
Realized gains and losses on security transactions are determined on the
identified cost basis. Dividend income is recorded on the ex-dividend dates.
Interest income is recognized on the accrual basis. The fund amortizes all
premiums and discounts on debt securities.

(e) Dividends and distributions -- Dividends from net investment income are
declared and paid monthly. Distributions of capital gains are recorded on the
ex-dividend dates.

2. Investment Advisory Agreement and Transactions with Affiliates:

The Fund has entered into an Investment Advisory Agreement with Fund Asset
Management, L.P. ("FAM"). The general partner of FAM is Princeton Services, Inc.
("PSI"), an indirect, wholly-owned subsidiary of Merrill Lynch & Co., Inc. ("ML

necessary personnel, facilities, equipment and certain other services necessary

*     On October 31, 2003, the Fund had a net capital loss carryforward of
      $12,682,535, of which $2,049,123 expires in 2007, $5,722,654 expires in
      2008, $9,668 expires in 2009 and $4,901,090 expires in 2011. This amount
      will be available to offset like amounts of any future taxable gains.
**    The difference between book-basis and tax-basis net unrealized gains is
      attributable primarily to the tax deferral of losses on wash sales, the
      tax deferral of losses on straddles and the difference between book and
      tax amortization methods for premiums and discounts on fixed income
      securities.

Dividend Policy

The Fund's dividend policy is to distribute all or a portion of its net
investment income to its shareholders on a monthly basis. In order to provide
shareholders with a more stable level of dividend distributions, the Fund may at
times pay out less than the entire amount of net investment income earned in any
particular month and may at times in any particular month pay out such
accumulated but undistributed income in addition to net investment income earned
in that month. As a result, the dividends paid by the Fund for any particular
month may be more or less than the amount of net investment income earned by the
Fund during such month. The Fund's current accumulated but undistributed net
investment income, if any, is disclosed in the Statement of Net Assets, which
comprises part of the financial information included in this report.

Automatic Dividend Reinvestment Plan

The following description of the Fund's Automatic Dividend Reinvestment Plan
(the "Plan") is sent to you annually as required by Federal securities laws.

Pursuant to the Fund's Plan, unless a holder of Common Stock otherwise elects,
all dividend and capital gains distributions will be automatically reinvested by
EquiServe (the "Plan Agent"), as agent for shareholders in administering the
Plan, in additional shares of Common Stock of the Fund. Holders of Common Stock
who elect not to participate in the Plan will receive all distributions in cash
paid by check mailed directly to the shareholder of record (or, if the shares
are held in street or other nominee name then to such nominee) by EquiServe, as
dividend paying agent. Such participants may elect not to participate in the
Plan and to receive all distributions of dividends and capital gains in cash by
sending written instructions to EquiServe, as dividend paying agent, at the
address set forth below. Participation in the Plan is completely voluntary and
may be terminated or resumed at any time without penalty by written notice if
received by the Plan Agent not less than ten days prior to any dividend record
date; otherwise such termination will be effective with respect to any
subsequently declared dividend or distribution.

Whenever the Fund declares an income dividend or capital gains distribution
(collectively referred to as "dividends") payable either in shares or in cash,
non-participants in the Plan will receive cash and participants in the Plan will
receive the equivalent in shares of Common Stock. The shares will be acquired by
the Plan Agent for the participant's account, depending upon the circumstances
described below, either (i) through receipt of additional unissued but
authorized shares of Common Stock from the Fund ("newly issued shares") or (ii)
by purchase of outstanding shares of Common Stock on the open market
("open-market purchases") on the New York Stock Exchange or elsewhere. If on the
payment date for the dividend, the net asset value per share of the Common Stock
is equal to or less than the market price per share of the Common Stock plus
estimated brokerage commissions (such conditions being referred to herein as
"market premium"), the Plan Agent will invest the dividend amount in newly
issued shares on behalf of the participant. The number of newly issued shares of
Common Stock to be credited to the participant's account will be determined by
dividing the dollar amount of the dividend by the net asset value per share on
the date the shares are issued, provided that the maximum discount from the then
current market price per share on the date of issuance may not exceed 5%. If on
the dividend payment date the net asset value per share is greater than the
market value (such condition being referred to herein as "market discount"), the
Plan Agent will invest the dividend amount in shares acquired on behalf of the
participant in open-market purchases.

In the event of a market discount on the dividend payment date, the Plan Agent
will have until the last business day before the next date on which the shares
trade on an "ex-dividend" basis or in no event more than 30 days after the
dividend payment date (the "last purchase date") to invest the dividend amount
in shares acquired in open-market purchases. It is contemplated that the Fund
will pay monthly income dividends. Therefore, the period during which
open-market purchases can be made will exist only from the payment date on the
dividend through the date before the next "ex-dividend" date, which typically
will be approximately ten days. If, before the Plan Agent has completed its
open-market purchases, the market price of a share of Common Stock exceeds the
net asset value per share, the average per share purchase price paid by the Plan
Agent may exceed the net asset value of the Fund's shares, resulting in the
acquisitions of fewer shares than if the dividend had been paid in newly issued
shares on the dividend payment date. Because of the foregoing difficulty with
respect to open-market purchases, the Plan provides that if the Plan Agent 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 Agent will cease making open-market purchases and will
invest the uninvested portion of the dividend amount in newly issued shares at
the close of business on the last purchase date determined by dividing the
uninvested portion of the dividend by the net asset value per share.

The Plan Agent maintains all shareholders' accounts in the Plan and furnishes
written confirmation of all transactions in the account, including information
needed by shareholders for tax records. Shares in the account of each Plan
participant will be held by the Plan Agent in non-certificated form in the name
of the participant, and each shareholder's proxy will include those shares
purchased or received pursuant to the Plan. The Plan Agent will forward all
proxy solicitation materials to participants and vote proxies for shares held
pursuant to the Plan in accordance with the instructions of the participants.

In the case of shareholders such as banks, brokers or nominees which hold shares
of others who are the beneficial owners, the Plan Agent will administer the Plan
on the basis of the number of shares certified from time to time by the record
shareholders


22      MUNIYIELD CALIFORNIA INSURED FUND, INC.     OCTOBER 31, 2003


Automatic Dividend Reinvestment Plan (concluded)

as representing the total amount registered in the record shareholder's name and
held for the account of beneficial owners who are to participate in the Plan.

There will be no brokerage charges with respect to shares issued directly by the
Fund as a result of dividends or capital gains distributions payable either in
shares or in cash. However, each participant will pay a pro rata share of
brokerage commissions incurred with respect to the Plan Agent's open-market
purchases in connection with the reinvestment of dividends.

The automatic reinvestment of dividends and distributions will not relieve
participants of any Federal, state or local income tax that may be payable (or
required to be withheld) on such dividends.

Shareholders participating in the Plan may receive benefits not available to
shareholders not participating in the Plan. If the market price plus commissions
of the Fund's shares is above the net asset value, participants in the Plan will
receive shares of the Fund at less than they could otherwise purchase them and
will have shares with a cash value greater than the value of any cash
distribution they would have received on their shares. If the market price plus
commissions is below the net asset value, participants will receive
distributions in shares with a net asset value greater than the value of any
cash distribution they would have received on their shares. However, there may
be insufficient shares available in the market to make distributions in shares
at prices below the net asset value. Also, since the Fund does not redeem
shares, the price on resale may be more or less than the net asset value.

The value of shares acquired pursuant to the Plan will generally be excluded
from gross income to the extent that the cash amount reinvested would be
excluded from gross income. If, when the Fund's shares are trading at a premium
over net asset value, the Fund issues shares pursuant to the Plan that have a
greater fair market value than the amount of cash reinvested, it is possible
that all or a portion of such discount (which may not exceed 5% of the fair
market value of the Fund's shares) could be viewed as a taxable distribution. If
the discount is viewed as a taxable distribution, it is also possible that the
taxable character of this discount would be allocable to all the shareholders,
including shareholders who do not participate in the Plan. Thus, shareholders
who do not participate in the Plan might be required to report as ordinary
income a portion of their distributions equal to their allocable share of the
discount.

Experience under the Plan may indicate that changes are desirable. Accordingly,
the Fund reserves the right to amend or terminate the Plan. There is no direct
service charge to participants in the Plan; however, the Fund reserves the right
to amend the Plan to include a service charge payable by the participants.

All correspondence concerning the Plan should be directed to the Plan Agent at
EquiServe, P.O. Box 43010, Providence, RI 02940-3010, Telephone: 800-426-5523.

MuniYield California Insured Fund, Inc. seeks to provide shareholders with as
high a level of current income exempt from Federal and California income taxes
as is consistent with its investment policies and prudent investment management
by investing primarily in a portfolio of long-term investment-grade municipal
obligations the interest on which, in the opinion of bond counsel to the issuer,
is exempt from Federal and California income taxes.

Item 6 - Reserved

Item 7 - For closed-end funds that contain voting securities in their portfolio,
         describe the policies and procedures that it uses to determine how to
         vote proxies relating to those portfolio securities.

         Proxy Voting Policies and Procedures



         Each Fund's Board of Directors/Trustees has delegated to Merrill Lynch
         Investment Managers, L.P. and/or Fund Asset Management, L.P. (the
         "Investment Adviser") authority to vote all proxies relating to the
         Fund's portfolio securities. The Investment Adviser has adopted
         policies and procedures ("Proxy Voting Procedures") with respect to the
         voting of proxies related to the portfolio securities held in the
         account of one or more of its clients, including a Fund. Pursuant to
         these Proxy Voting Procedures, the Investment Adviser's primary
         objective when voting proxies is to make proxy voting decisions solely
         in the best interests of each Fund and its shareholders, and to act in
         a manner that the Investment Adviser believes is most likely to enhance
         the economic value of the securities held by the Fund. The Proxy Voting
         Procedures are designed to ensure that the Investment Adviser considers
         the interests of its clients, including the Funds, and not the
         interests of the Investment Adviser, when voting proxies and that real
         (or perceived) material conflicts that may arise between the Investment
         Adviser's interest and those of the Investment Adviser's clients are
         properly addressed and resolved.

         In order to implement the Proxy Voting Procedures, the Investment
         Adviser has formed a Proxy Voting Committee (the "Committee"). The
         Committee is comprised of the Investment Adviser's Chief Investment
         Officer (the "CIO"), one or more other senior investment professionals
         appointed by the CIO, portfolio managers and investment analysts
         appointed by the CIO and any other personnel the CIO deems appropriate.
         The Committee will also include two non-voting representatives from the
         Investment Adviser's Legal department appointed by the Investment
         Adviser's General Counsel. The Committee's membership shall be limited
         to full-time employees of the Investment Adviser. No person with any
         investment banking, trading, retail brokerage or research
         responsibilities for the Investment Adviser's affiliates may serve as a
         member of the Committee or participate in its decision making (except
         to the extent such person is asked by the Committee to present
         information to the Committee, on the same basis as other interested
         knowledgeable parties not affiliated with the Investment Adviser might
         be asked to do so). The Committee determines how to vote the proxies of
         all clients, including a Fund, that have delegated proxy voting
         authority to the Investment Adviser and seeks to ensure that all votes
         are consistent with the best interests of those clients and are free
         from unwarranted and inappropriate influences. The Committee
         establishes general proxy voting policies for the Investment Adviser
         and is responsible for determining how those policies are applied to
         specific proxy votes, in light of each issuer's unique structure,
         management, strategic options and, in certain circumstances, probable
         economic and other anticipated consequences of alternate actions. In so
         doing, the Committee may determine to vote a particular proxy in a
         manner contrary to its generally stated policies. In addition, the
         Committee will be responsible for ensuring that all reporting and
         recordkeeping requirements related to proxy voting are fulfilled.

         The Committee may determine that the subject matter of a recurring
         proxy issue is not suitable for general voting policies and requires a
         case-by-case determination. In such cases, the Committee may elect not
         to adopt a specific voting policy applicable to that issue. The
         Investment Adviser believes that certain proxy voting issues require
         investment analysis - such as approval of mergers and other significant
         corporate transactions - akin to investment decisions, and are,
         therefore, not suitable for general guidelines. The Committee may elect
         to adopt a common position for the Investment Adviser on certain proxy
         votes that are akin to investment decisions, or determine to permit the
         portfolio manager to make individual decisions on how best to maximize
         economic value for a Fund (similar to normal buy/sell investment
         decisions made by such portfolio managers). While it is expected that
         the Investment Adviser will generally seek to vote proxies over which
         the Investment Adviser exercises voting authority in a uniform manner
         for all the Investment Adviser's clients, the Committee, in conjunction
         with a Fund's portfolio manager, may determine that the Fund's specific
         circumstances require that its proxies be voted differently.

         To assist the Investment Adviser in voting proxies, the Committee has
         retained Institutional Shareholder Services ("ISS"). ISS is an
         independent adviser that specializes in providing a variety of
         fiduciary-level proxy-related services to institutional investment
         managers, plan sponsors, custodians, consultants, and other
         institutional investors. The services provided to the Investment
         Adviser by ISS include in-depth research, voting recommendations
         (although the Investment Adviser is not obligated to follow such
         recommendations), vote execution, and recordkeeping. ISS will also
         assist the Fund in fulfilling its reporting and recordkeeping
         obligations under the Investment Company Act.



         The Investment Adviser's Proxy Voting Procedures also address special
         circumstances that can arise in connection with proxy voting. For
         instance, under the Proxy Voting Procedures, the Investment Adviser
         generally will not seek to vote proxies related to portfolio securities
         that are on loan, although it may do so under certain circumstances. In
         addition, the Investment Adviser will vote proxies related to
         securities of foreign issuers only on a best efforts basis and may
         elect not to vote at all in certain countries where the Committee
         determines that the costs associated with voting generally outweigh the
         benefits. The Committee may at any time override these general policies
         if it determines that such action is in the best interests of a Fund.

From time to time, the Investment Adviser may be required to vote proxies in
respect of an issuer where an affiliate of the Investment Adviser (each, an
"Affiliate"), or a money management or other client of the Investment Adviser
(each, a "Client") is involved. The Proxy Voting Procedures and the Investment
Adviser's adherence to those procedures are designed to address such conflicts
of interest. The Committee intends to strictly adhere to the Proxy Voting
Procedures in all proxy matters, including matters involving Affiliates and
Clients. If, however, an issue representing a non-routine matter that is
material to an Affiliate or a widely known Client is involved such that the
Committee does not reasonably believe it is able to follow its guidelines (or if
the particular proxy matter is not addressed by the guidelines) and vote
impartially, the Committee may, in its discretion for the purposes of ensuring
that an independent determination is reached, retain an independent fiduciary to
advise the Committee on how to vote or to cast votes on behalf of the Investment
Adviser's clients.

         In the event that the Committee determines not to retain an independent
         fiduciary, or it does not follow the advice of such an independent
         fiduciary, the powers of the Committee shall pass to a subcommittee,
         appointed by the CIO (with advice from the Secretary of the Committee),
         consisting solely of Committee members selected by the CIO. The CIO
         shall appoint to the subcommittee, where appropriate, only persons
         whose job responsibilities do not include contact with the Client and
         whose job evaluations would not be affected by the Investment Adviser's
         relationship with the Client (or failure to retain such relationship).
         The subcommittee shall determine whether and how to vote all proxies on
         behalf of the Investment Adviser's clients or, if the proxy matter is,
         in their judgment, akin to an investment decision, to defer to the
         applicable portfolio managers, provided that, if the subcommittee
         determines to alter the Investment Adviser's normal voting guidelines
         or, on matters where the Investment Adviser's policy is case-by-case,
         does not follow the voting recommendation of any proxy voting service
         or other independent fiduciary that may be retained to provide research
         or advice to the Investment Adviser on that matter, no proxies relating
         to the Client may be voted unless the Secretary, or in the Secretary's
         absence, the Assistant Secretary of the Committee concurs that the
         subcommittee's determination is consistent with the Investment
         Adviser's fiduciary duties

         In addition to the general principles outlined above, the Investment
         Adviser has adopted voting guidelines with respect to certain recurring
         proxy issues that are not expected to involve unusual circumstances.
         These policies are guidelines only, and the Investment Adviser may
         elect to vote differently from the recommendation set forth in a voting
         guideline if the Committee determines that it is in a Fund's best
         interest to do so. In addition, the guidelines may be reviewed at any
         time upon the request of a Committee member and may be amended or
         deleted upon the vote of a majority of Committee members present at a
         Committee meeting at which there is a quorum.

         The Investment Adviser has adopted specific voting guidelines with
         respect to the following proxy issues:

o     Proposals related to the composition of the Board of Directors of issuers
      other than investment companies. As a general matter, the Committee
      believes that a company's Board of Directors (rather than shareholders) is
      most likely to have access to important, nonpublic information regarding a
      company's business and prospects, and is therefore best-positioned to set
      corporate policy and oversee management. The Committee, therefore,
      believes that the foundation of good corporate governance is the election
      of qualified, independent corporate directors who are likely to diligently
      represent the interests of shareholders and oversee management of the
      corporation in a manner that will seek to maximize shareholder value over
      time. In individual cases, the Committee may look at a nominee's history
      of representing shareholder interests as a director of other companies or
      other factors, to the extent the Committee deems relevant.



o     Proposals related to the selection of an issuer's independent auditors. As
      a general matter, the Committee believes that corporate auditors have a
      responsibility to represent the interests of shareholders and provide an
      independent view on the propriety of financial reporting decisions of
      corporate management. While the Committee will generally defer to a
      corporation's choice of auditor, in individual cases, the Committee may
      look at an auditors' history of representing shareholder interests as
      auditor of other companies, to the extent the Committee deems relevant.

o     Proposals related to management compensation and employee benefits. As a
      general matter, the Committee favors disclosure of an issuer's
      compensation and benefit policies and opposes excessive compensation, but
      believes that compensation matters are normally best determined by an
      issuer's board of directors, rather than shareholders. Proposals to
      "micro-manage" an issuer's compensation practices or to set arbitrary
      restrictions on compensation or benefits will, therefore, generally not be
      supported.

o     Proposals related to requests, principally from management, for approval
      of amendments that would alter an issuer's capital structure. As a general
      matter, the Committee will support requests that enhance the rights of
      common shareholders and oppose requests that appear to be unreasonably
      dilutive.

o     Proposals related to requests for approval of amendments to an issuer's
      charter or by-laws. As a general matter, the Committee opposes poison pill
      provisions.

o     Routine proposals related to requests regarding the formalities of
      corporate meetings.

o     Proposals related to proxy issues associated solely with holdings of
      investment company shares. As with other types of companies, the Committee
      believes that a fund's Board of Directors (rather than its shareholders)
      is best-positioned to set fund policy and oversee management. However, the
      Committee opposes granting Boards of Directors authority over certain
      matters, such as changes to a fund's investment objective, that the
      Investment Company Act envisions will be approved directly by
      shareholders.

o     Proposals related to limiting corporate conduct in some manner that
      relates to the shareholder's environmental or social concerns. The
      Committee generally believes that annual shareholder meetings are
      inappropriate forums for discussion of larger social issues, and opposes
      shareholder resolutions "micromanaging" corporate conduct or requesting
      release of information that would not help a shareholder evaluate an
      investment in the corporation as an economic matter. While the Committee
      is generally supportive of proposals to require corporate disclosure of
      matters that seem relevant and material to the economic interests of
      shareholders, the Committee is generally not supportive of proposals to
      require disclosure of corporate matters for other purposes.
