MuniYield California Insured Fund II, Inc.

DEAR SHAREHOLDER

For the year ended October 31, 1999, the Common Stock of MuniYield California
Insured Fund II, Inc. earned $0.857 per share income dividends, which included
earned and unpaid dividends of $0.069. This represents a net annualized yield of
6.52%, based on a month-end per share net asset value of $13.14. Over the same
period, the total investment return on the Fund's Common Stock was -10.76%,
based on a change in per share net asset value from $16.25 to $13.14, and
assuming reinvestment of $1.053 per share ordinary income dividends and $0.454
per share capital gains distributions.

For the six-month period ended October 31, 1999, the total investment return on
the Fund's Common Stock was -11.38%, based on a change in per share net asset
value from $15.27 to $13.14, and assuming reinvestment of $0.407 per share
income dividends.

For the six-month period ended October 31, 1999, the Fund's Auction Market
Preferred Stock had an average yield as follows: Series A, 2.71%; Series B,
3.11%; and Series C, 2.99%.

The Municipal Market Environment

The combination of steady strong domestic economic growth, improvement in
foreign economies (most notably in Japan) and increasing investor concerns
regarding potential increases in US inflation put upward pressure on bond yields
throughout the six-month period ended October 31, 1999. Continued strong US
employment growth, particularly the decline in the US unemployment rate to 4.2%
in early June, was among the reasons the Federal Reserve Board cited for raising
short-term interest rates in late June and again in late August. US Treasury
bond yields reacted by climbing above 6.375% by late October. However, at
October month-end, economic indicators were released suggesting that, despite
strong economic and employment growth in the third quarter, inflationary
pressures have remained extremely well-contained. This resulted in a significant
rally in the US Treasury bond market, pushing US Treasury bond yields downward
to end the 12-month period at approximately 6.15%. During the period, yields on
30-year US Treasury bonds increased over 50 basis points (0.50%).

Long-term tax-exempt bond yields also rose during the six months ended October
31, 1999. Until early May, the municipal bond market was able to withstand much
of the upward pressure on bond yields. However, investor concerns of additional
moves by the Federal Reserve Board to moderate US economic growth and, more
importantly, the loss of the strong technical support that the tax-exempt market
enjoyed in early 1999 helped push municipal bond yields significantly higher for
the remainder of the period. The yields on long-term tax-exempt revenue bonds
rose nearly 90 basis points to 6.18% by October 31, 1999, as measured by the
Bond Buyer Revenue Bond Index.

In recent months, the significant decline in new tax-exempt bond issuance has
remained a positive factor within the municipal bond market, as it had been for
much of the past year. During the last six months, more than $110 billion in
long-term municipal bonds was issued, a decline of nearly 20% compared to the
same period a year ago. During the past three months, $55 billion in municipal
bonds was underwritten, representing a decline of nearly 10% compared to the
corresponding period in 1998. Additionally, in June and July, investors received
more than $40 billion in coupon income and proceeds from bond maturities and
early bond redemptions. These proceeds have generated considerable retail
investor interest, which has helped absorb the recent diminished supply.

Although tax-exempt bond yields are at their highest level in over two years and
have attracted significant retail investor interest, institutional demand has
declined sharply. Long-term municipal mutual funds have seen consistent outflows
in recent months as the yields of individual securities have risen faster than
those of larger, more diverse mutual funds. In addition, the demand from
property/casualty insurance companies has weakened as a result of the losses,
and anticipated losses, incurred as a result of the series of damaging storms
across much of the eastern United States. Additionally, many institutional
investors who were attracted to the municipal bond market in recent years by
historically attractive tax-exempt bond yield ratios of over 90% have found
other asset classes even


                                                                               1

more attractive. Even with a reduced supply position, tax-exempt issuers have
been forced to repeatedly raise municipal bond yields in the attempt to attract
adequate demand.

The recent relative underperformance of the municipal bond market has resulted
in an opportunity for long-term investors to purchase tax-exempt issues whose
yields are nearly identical with taxable US Treasury securities. At October 31,
1999, long-term uninsured municipal revenue bond yields were 100% of comparable
US Treasury securities. In recent months, many taxable asset classes, such as
corporate bonds, mortgage-backed securities and US agency debt, have all
accelerated debt issuance. This acceleration was initiated largely to avoid
issuing securities at year-end and to minimize any associated Year 2000 (Y2K)
problems that may develop. However, this increased issuance has also resulted in
higher yield levels in the various asset classes as lower bond prices became
necessary to attract sufficient investor demand. Going forward, it is believed
that the pace of non-US government debt issuance is likely to slow
significantly. As the supply of this debt declines, we would expect many
institutional investors to return to the municipal bond market and the
attractive yield ratios available.

Looking ahead, it appears to us that long-term tax-exempt bond yields will
remain under pressure, trading in a broad range centered near current levels.
Investors are likely to remain concerned about future action by the Federal
Reserve Board in November. Y2K considerations may prohibit any further Federal
Reserve Board moves through the end of the year and the beginning of 2000. Any
improvement in bond prices will probably be contingent upon weakening in both US
employment growth and consumer spending. The 100 basis point rise in US Treasury
bond yields seen thus far this year may negatively impact US economic growth.
The US housing market will be among the first sectors likely to be affected, as
some declines have already been evidenced in response to higher mortgage rates.
We believe that it is also unrealistic to expect double-digit returns in US
equity markets to continue indefinitely. Much of the US consumer's wealth is
tied to recent stock market appreciation. Any slowing in these incredible growth
rates is likely to reduce consumer spending. We believe that these factors
suggest that the worst of the recent increase in bond yields has passed and
stable, if not slightly improving, bond prices may be expected.

Portfolio Strategy

During the six-month period ended October 31, 1999, we managed the Fund with the
intent of sustaining an attractive level of tax-exempt income for our
shareholders. Our strategy was to remain invested in the highest-yielding bonds
that we could purchase without sacrificing credit quality. Unfortunately, during
the six-month period, tax-exempt interest rates increased about 90 basis points.
While this caused the Fund's net asset value to drop, it gave us the opportunity
to purchase bonds with higher yields, increasing the Fund's income.

Looking ahead, we believe that the back up in interest rates has been excessive
relative to the amount of inflation that is evident in the economy. Therefore,
with interest rates at what we believe to be attractive levels, we will invest
the remainder of the Fund's cash reserves in an effort to increase the
tax-exempt income of the Fund. (For a complete explanation of the benefits and
risks of leveraging, see page 4 of this report to shareholders.)

In Conclusion

We appreciate your ongoing interest in MuniYield California Insured Fund II,
Inc., and we look forward to assisting you with your financial needs in the
months and years to come.

Sincerely,

MANAGED DIVIDEND POLICY

The Fund's dividend policy is to distribute substantially all of its net
investment income to its shareholders on a monthly basis. However, in order to
provide shareholders with a more consistent yield to the current trading price
of shares of Common Stock of the Fund, 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 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 Assets, Liabilities and Capital, which comprises
part of the Financial Information included in this report.

THE BENEFITS AND RISKS OF LEVERAGING

MuniYield California Insured Fund II, 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 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.

NOTES TO FINANCIAL STATEMENTS

1. Significant Accounting Policies:

MuniYield California Insured Fund II, Inc. (the "Fund") is registered under the
Investment Company Act of 1940 as a non-diversified, closed-end management
investment company. The Fund's financial statements are prepared in accordance
with generally accepted accounting principles, 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 most recent bid price or yield
equivalent as obtained by the Fund's pricing service from 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). Securities with remaining
maturities 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
strategies to seek to increase its return by hedging its portfolio against
adverse movements in the debt 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 for the purpose of hedging the
market risk on existing securities or the intended purchase of securities.
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).

Written and purchased options are non-income producing investments.

(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).
Interest income is recognized on the accrual basis. Discounts and market
premiums are amortized into interest income. Realized gains and losses on
security transactions are determined on the identified cost basis.

(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. Distributions in excess of realized


12

MuniYield California Insured Fund II, Inc.                      October 31, 1999

capital gains are due primarily to differing tax treatments for future
transactions and post-October losses.

(f) Reclassification -- Generally accepted accounting principles require that
certain components of net assets be adjusted to reflect permanent differences
between financial and tax reporting. Accordingly, current year's permanent
book/tax differences of $17,184 have been reclassified between paid-in capital
in excess of par and undistributed net investment income and $2,087 has been
reclassified between accumulated distributions in excess of net realized capital
gains and undistributed net investment income. These reclassifications have no
effect on net assets or net asset value per share.

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 &
Co."), which is the limited partner.

FAM is responsible for the management of the Fund's portfolio and provides the
necessary personnel, facilities, equipment and certain other services necessary
to the operations of the Fund. For such services, the Fund pays a monthly fee at
an annual rate of .50% of the Fund's average weekly net assets, including
proceeds from the issuance of Preferred Stock.

Accounting services are provided to the Fund by FAM at cost.

Certain officers and/or directors of the Fund are officers and/or directors of
FAM, PSI, and/or ML & Co.

3. Investments:

Purchases and sales of investments, excluding short-term securities, for the
year ended October 31, 1999 were $332,224,327 and $350,558,728, respectively.

As of October 31, 1999, net unrealized depreciation for Federal income tax
purposes aggregated $20,712,495, of which $3,100,575 related to appreciated
securities and $23,813,070 related to depreciated securities. The aggregate cost
of investments at October 31, 1999 for Federal income tax purposes was
$389,193,196.

4. Capital Stock Transactions:

The Fund is authorized to issue 200,000,000 shares of capital stock, including
Preferred Stock, par value $.10 per share, all of which were initially
classified as Common Stock. The Board of Directors is authorized, however, to
reclassify any unissued shares of capital stock without approval of holders of
Common Stock.

Common Stock

Shares issued and outstanding during the year ended October 31, 1999 increased
by 277,909 as a result of dividend reinvestment and during the year ended
October 31, 1998 remained constant.

Preferred Stock

Auction Market Preferred Stock ("AMPS") are shares of Preferred Stock of the
Fund, with a par value of $.10 per share and a liquidation preference of $25,000
per share, that entitle their holders to receive cash dividends at an annual
rate that may vary for the successive dividend periods. The yields in effect at
October 31, 1999 were as follows: Series A, 3.00%; Series B, 2.25%; and Series
C, 2.91%.

Shares issued and outstanding during the years ended October 31, 1999 and
October 31, 1998 remained constant.

The Fund pays commissions to certain broker-dealers at the end of each auction
at an annual rate ranging from .25% to .375%, calculated on the proceeds of each
auction. For the year ended October 31, 1999, Merrill Lynch, Pierce, Fenner &
Smith Incorporated, an affiliate of FAM, earned $138,808 as commissions.

5. Capital Loss Carryforward:

At October 31, 1999, the Fund had a net capital loss carryforward of
approximately $4,997,000, all of which expires in 2007. This amount will be
available to offset like amounts of any future taxable gains.

6. Subsequent Event:

On November 8, 1999, the Fund's Board of Directors declared an ordinary income
dividend to Common Stock shareholders in the amount of $.069000 per share,
payable on November 29, 1999 to shareholders of record as of November 22, 1999.


                                                                            13

YEAR 2000 ISSUES

Many computer systems were designed using only two digits to designate years.
These systems may not be able to distinguish the Year 2000 from the Year 1900
(commonly known as the "Year 2000 Problem"). The Fund could be adversely
affected if the computer systems used by the Fund's management or other Fund
service providers do not properly address this problem before January 1, 2000.
The Fund's management expects to have addressed this problem before then, and
does not anticipate that the services it provides will be adversely affected.
The Fund's other service providers have told the Fund's management that they
also expect to resolve the Year 2000 Problem, and the Fund's management will
continue to monitor the situation as the Year 2000 approaches. However, if the
problem has not been fully addressed, the Fund could be negatively affected. The
Year 2000 Problem could also have a negative impact on the securities in which
the Fund invests and this could hurt the Fund's investment returns.
