VANGUARD
CALIFORNIA
TAX-FREE FUND

ANNUAL REPORT 1995

<PAGE>   2
In this Annual Report, I am delighted to formally introduce you to John J.
Brennan, who, on January 31, 1996, will assume my responsibilities as Chief
Executive Officer of Vanguard California Tax-Free Fund and the other Funds in
The Vanguard Group. Mr. Brennan will continue to serve as President of the
Funds, and I will continue to serve as Chairman of the Board.

     As Chairman of all the Vanguard Funds, I want to tell you that I am
enthusiastic and confident that Jack Brennan is exactly the right person to
succeed me as Chief Executive Officer. To use yet another Vanguard nautical
metaphor, he will be the new captain. He has the qualities of leadership,
integrity, intelligence, and vision that must continue to be Vanguard's
hallmark as we move toward, and then into, the 21st century.

     I know that he has these qualities, because Jack Brennan and I have
been working closely together since he joined Vanguard in 1982. He is a
graduate of Dartmouth College and Harvard Business School. He started as
Assistant to the Chairman and, rising like a rocket, became President in 1989.
While, at age 41, he may seem young, he is in fact older than I was when I
became Chief Executive Officer of Vanguard's predecessor organization in 1967,
at the age of 38. Most important of all, Jack is completely dedicated to the
Vanguard character, and believes in our basic mission: serving solely the
shareholder, free of any conflict of interest. He believes in holding our costs
of operation to a minimum, and in retaining our position as the lowest-cost
provider of financial services in the world. He is a true competitor, who
shares Vanguard's dedication to providing highly competitive returns to our
investors relative to the returns provided by other mutual funds with
comparable objectives. He also believes in reporting our results to
shareholders with complete candor. He has the full support of the Board of
Directors and our crew, and is committed to staying the course we have set for
Vanguard. You need have no doubt that the essential elements that drew you to
Vanguard in the first place will remain intact.

     As for me, I expect to fill a useful, if less demanding, role as
Chairman of the Board. I shall keep a watchful eye over the interests of our
shareholders, our crew, and our investment policies. I shall also speak out on
industry affairs, reminding all who will listen of the primacy of the interests
of mutual fund shareholders. I will be readily available to provide Jack
Brennan with whatever wisdom I may have acquired during my lifetime of
experience in this wonderful industry and in my service as captain of Vanguard
since I founded this unique organization more than two decades ago.

     In short, I'll still be around. Thank you for all your confidence in me
in the past and, in advance, for your continued confidence in Vanguard under
Jack Brennan's leadership.

                               CHAIRMAN'S LETTER

DEAR SHAREHOLDER:

The 1995 fiscal year for Vanguard State Tax-Free Funds, which ended on November
30, presented a sharp contrast to fiscal 1994.  During our prior fiscal year,
long-term interest rates rose sharply, engendering a commensurate drop in bond
prices; during our most recent fiscal year, long-term interest rates fell
steadily, driving bond prices upward. In the short-term arena, tax-exempt
interest rates moved lower during the 1995 fiscal year, but the yields on our
State Money Market Portfolios actually edged higher.

         The net result of the turnabout in the course of long-term interest
rates was greatly enhanced returns to the shareholders of our Insured Long-Term
Portfolios. Given the relatively low interest rate environment that prevailed
during fiscal 1995 in the tax-exempt money markets, shareholders in our various
State Money Market Portfolios earned modest returns.  Nonetheless, our Money
Market Portfolios' returns were comfortably above the returns achieved by their
respective competitive benchmarks. The detailed fiscal year results for each of
our State Tax-Free Portfolios, including net asset values and dividends for the
year, as well as current yields, are presented in a table at the conclusion of
this letter.

         Over the past twelve months, the STATE MONEY MARKET PORTFOLIOS
provided returns in the area of +3.7%. As we would expect, all of our
Portfolios' net asset values remained at $1.00 per share throughout the year.
The table below provides an overview of each Portfolio's twelve-month total
return, as well as its yield at the beginning and the end of the fiscal year:

- --------------------------------------------------------------
</TABLE>                                         


Modest though these yields may be, they accrue to investors without 
taxation at either the Federal level or the state and local levels in the
respective states. What's more, the yield of each Portfolio represents a nice
enhancement over the yield available from comparable competitive funds. As a
result of this consistent yield premium, our Portfolios' longer-term returns
have exceeded those of competitive standards. In the case of the California
Money Market Portfolio, shareholders have earned an average annual return of
+4.1% since the Portfolio's inception in June 1987, compared to +3.8% for the
average California money market fund.

         The STATE INSURED LONGER-TERM PORTFOLIOS recouped all of last year's 
capital losses--and then some--turning in their best overall year of
performance since our first Insured Portfolios began operations in April 1986.
The following table summarizes the fiscal year total returns (capital change
plus income) for all of the Insured Longer-Term Portfolios. To provide some
perspective on just how beneficial the falling interest rates of the past twelve
months have been for holders of longer-term bonds, this table breaks down our
Portfolios' total returns into their income and capital components:

more or less comes with the territory. With that caveat in mind, it would not
be unexpected if the capital reward of fiscal 1995 were to revert to a capital
penalty sooner or later in another fiscal year.

         The Portfolios' strong absolute returns of the past year also stack up
pretty well relative to the results of their two most appropriate performance
benchmarks: the unmanaged Lehman Municipal Bond Index and the average
competitive fund in each respective state category. The chart above shows the
cumulative returns earned by the California Insured Long-Term Portfolio since
its inception in April 1986, compared with each of these benchmarks. The
lifetime results for the Insured Intermediate-Term Portfolio are presented on
page 5.

         You will note that the +8.1% annualized return for the California
Insured Long-Term Portfolio was a bit ahead of the +7.7% return for the average
California insured municipal fund. Despite our emphasis on high quality and our
reliance on the extra credit safety of insured bonds, our cost advantage
carried the day. However, our return fell shy of the +8.4% return for the
Lehman Municipal Bond Index. The California Insured Intermediate-Term Portfolio
achieved a return of +7.6%, well ahead of the +6.6% return of its average
competitor, but well behind the longer maturity Lehman Municipal Bond Index. As
you know, this Index is a tough standard for all state tax-free funds, given
that it exists in a world devoid of fund operating expenses and transaction
costs. While we endeavor to exceed this Index standard after our expenses,
doing so on a consistent basis may prove to be a large challenge.

THE FISCAL YEAR IN REVIEW

Above all, fiscal 1995 can be viewed as a year of recovery in the bond market.
On balance for the fiscal year, the yield on the long-term U.S. Treasury bond
tumbled from 8.0% to 6.1%, a precipitous drop of 190 basis points, equivalent
to a +26% price increase excluding the generous interest coupon. The yield on
the 90-day U.S. Treasury bill also declined--albeit not nearly as
sharply--beginning the fiscal year at 5.8% and ending at 5.5%.





                                       2
<PAGE>   5
[FIGURE 3]

         During this same period, the municipal bond market moved in similar
fashion; however, the decline in long-term municipal bond yields was somewhat
more subdued. On balance for the fiscal year, yields on high-grade municipal
bonds fell from 6.9% to 5.5%, engendering a price increase of +20%. Yields on
top-grade (MIG 1) municipal notes declined from 3.8% to 3.5%.

         In my view, the abrupt decline in long-term interest rates over the
past twelve months was related to several contributing factors. Most
importantly, we should not lose sight of the fact that interest rates had risen
virtually without interruption in the months leading up to the commencement of
our 1995 fiscal year, reaching a peak in November 1994. This climb in rates was
engendered largely by investors' fears about a resurgence of inflation. With
the Federal Reserve Board raising the Federal funds rate (the rate at which
banks borrow from one another) an unprecedented seven times in the 13 months
from February 1994 to February 1995, these inflation fears certainly seemed
well-founded.

         Although restrictive monetary policy often fails to deliver the
desired result, in this case the Fed's medicine seemed to work as intended.
That is, U.S. economic growth slowed and inflation concerns gradually
dissipated. Reflecting this renewed investor optimism, long-term rates did an
about-face beginning in late January 1995 and began to move steadily lower. By
the time the summer of 1995 began, the Fed felt free to relax its stern
monetary policy and actually reduced the Federal funds rate by 1/4 of 1% to 
5 3/4%.*

         The chart to the left should place the events of the past two fiscal
years into a somewhat longer run perspective. You will note that the first
three years witnessed a steady downtrend in rates, followed by the abrupt
two-year cycle that I just described. Yet, when all is said and done, yields on
long-term municipal bonds today remain generally below the levels maintained
during fiscal 1991-1992. In other words, despite the "slings and arrows" of the
recent volatile period, the prices of municipal bonds are higher today than
during the early years of the period.

         It is interesting to trace the relative yields of long and short
municipals over the past five years. You can see in the lower chart that the
difference between the two yields--the "spread," if you will--has come
virtually full circle over the past five years. It stood at 135 basis points
(1.35%) at the beginning of fiscal 1991, climbed to nearly 400 basis points by
the end of fiscal 1992, and has narrowed considerably since then, moving back
to roughly 200 basis points at the close of the past fiscal year. What this
means is that investors who choose to extend the maturity of their bond
holdings earn a much lower risk premium today than they did some three years
ago.

TAX-EXEMPT VERSUS TAXABLE YIELDS

It is perhaps obvious that the reason investors are willing to accept
relatively lower yields from municipal bonds is the tax-exempt status of these

 fiscal year.

securities. While the after-tax advantage of municipals is often taken for
granted, whether municipals represent an appropriate alternative depends
importantly on: (1) the investor's tax bracket; and (2) the yield spread
between taxable and tax-exempt securities.

         When I wrote to you one year ago in my 1994 Chairman's letter, I noted
that, for investors in the highest marginal tax bracket, long-term municipal
bonds provided 44% higher after-tax income compared to Federally taxable U.S.
Treasury bonds.  Today, that yield advantage has widened to 49%. However, on
the short side of the yield spectrum, the after-tax yield premium of MIG 1
notes over U.S. Treasury bills has shrunk, from 9% to 6%. This table presents a
comparison of the annual income earned on tax-exempt and taxable securities as
of November 30, 1995, assuming a $100,000 investment:

Table assumes current yields (as of November 30, 1995) of 6.1% for U.S.
Treasury bonds, 5.5% for U.S. Treasury bills, 5.5% for long-term municipal
bonds, and 3.5% for short-term municipal notes.

The table provides a good indication of the kind of boost in after-tax income
that a high-tax-bracket investor might receive by investing in a state tax-free
bond fund rather than a Federally taxable U.S. Treasury bond fund. However,
given the speed with which interest rates can fluctuate, the illustration
should not be considered a representation of future results.

         In fairness, I should also add that this is not entirely an "apples to
apples" comparison. As you know, U.S. Treasury bonds are backed by the full
faith and credit of the U.S. government; municipal bonds, on the other hand,
are subject to some degree of credit risk. More to the point, state-specific
funds entail an incremental risk engendered by their high concentration of
investments in discrete economic regions of the country. This risk is mitigated
to a tremendous extent in our Insured Longer-Term Portfolios through the use of
private portfolio insurance for virtually all of the bonds held in the
portfolios. This insurance effectively guarantees the full payment of annual
income and, at maturity, principal for all of the insured bonds that we hold.
As a result, each of our Insured Longer-Term Portfolios carries an implied
average quality rating of Aaa, the highest rating accorded by Moody's Investors
Services.

         In the case of our State Tax-Free Money Market Portfolios, similar
portfolio insurance generally is not available.  Thus, the burden of assuring
the creditworthiness of each individual portfolio holding rests squarely on the
shoulders of the professional money managers in Vanguard's Fixed Income Group.
I am pleased to say that they have handled this task over the years with
considerable diligence, emphasizing high-quality and credit-enhanced
securities. (This "credit enhancement" consists largely of irrevocable letters
of credit from high-quality banks guaranteeing the timely payment of interest
and principal.) Their efforts have resulted in each of the holdings in our
Money Market Portfolios earning Moody's highest rating--or the equivalent--for
shorter-term instruments.

         Notwithstanding the quality of our portfolio holdings, investors in
all money market funds should bear in mind that their investments are not
guaranteed by the Federal Deposit Insurance Corporation, as would be the case
for an investment in a bank account or a certificate of deposit. There is also
no assurance that a money market fund will be able to maintain a stable net
asset value of $1.00 per share. However, we believe that our diligent credit
analysis and strict adherence to conservative average maturity guidelines will
go a long way toward protecting the interests of our shareholders.

IN SUMMARY

When I wrote to you in my Annual Report one year ago, near the low point in the
tax-exempt bond market, I was optimistic enough to predict that "during fiscal
1995 the probabilities now favor greater stability in long-term tax-exempt
rates, and somewhat higher short-term rates." As it turns out, short rates
actually slipped a bit lower, and I was not nearly optimistic enough on the
bond side, as a strong rebound in the bond market commenced virtually in
lock-step with the start of the new fiscal year. This recovery--reflecting the
traditional view that the dawn inevitably follows the darkness--provided a
substantive enhancement to shareholders in our Insured Longer-Term Portfolios.
It also reinforced the value of my traditional admonition to shareholders to
"stay the course."

         In the coming year, we, too, fully intend to stay the course that has
served our investors so well for so many years.  We will continue to focus on
providing returns that exceed those of appropriate competitive standards, but
we will do so with the highest standards of credit quality. While high credit
quality typically comes at a price--i.e., lower gross yields--our shareholders,
thanks to our exceptionally low expense ratios, need not sacrifice income for
quality. Indeed, while the average competitive state tax-free fund charges
annual expenses at the rate of 0.83% of average net assets, our Vanguard State
Tax-Free Portfolios incur an expense ratio of but 0.20%. This remarkable annual
benefit of 63 basis points is available through the Vanguard State Tax-Free
Funds with no sacrifice in quality. The resulting higher yields in a
higher-quality bond fund is as close to the proverbial "free lunch" as you are
likely to see.

         Thank you for your continued support and commitment to Vanguard, and I
look forward to reporting to you again six months hence.

Sincerely,

/s/ JOHN C. BOGLE

A FEW WORDS ABOUT POSSIBLE CHANGES IN THE TAX LAW

In our last Semi-Annual Report, we mentioned that potential changes in the tax
laws had impacted the tax-exempt bond market, resulting in an unusually large
after-tax yield advantage for municipal bonds. Since then, Congress has
continued to debate the merits of a "flat tax," with no definitive resolution
in sight. Given this uncertainty, the current yield on municipal bonds remains
at approximately 90% of the yield on taxable U.S. Treasuries. As a result, an
investor in the highest marginal tax bracket (40%), can earn an after-tax yield
of about 3.7% (60% of 6.1%) on a U.S. Treasury bond, compared to 5.5% on a
high-grade municipal bond--an increase of nearly 50% in after-tax income.

         Until the long-term implications of a revised tax code become clearer,
we would caution municipal bond investors to give careful consideration before
making precipitate changes in the allocation of their holdings of municipal
bonds. In the meantime, we will keep you abreast of our views on the possible
effects of any proposed legislation that could materially impact the tax status
of your holdings in Vanguard State Tax-Free Funds.

                       REPORT FROM THE INVESTMENT ADVISER

STATE INSURED LONG-TERM PORTFOLIOS

      It seems hard to believe that just one year ago we experienced the worst
price decline for the fixed-income markets since the 1920s. A powerful market
rally during 1995 has recaptured 1994's "lost ground." In retrospect, we are
reminded of the relevance of our Chairman's advice to "stay the course" in
weathering periods of market volatility.

      The Federal Reserve's 1994 tightening of monetary policy helped raise
short-term interest rates, which translated into a slowing of economic activity
this year. Such slowing has diminished inflationary pressure. Fixed-income
investors responded by aggressively buying bonds. During our 1995 fiscal year,
the yield on the 30-year Treasury bond fell 1.9 percentage points (from 8.0% to
6.1%). During the same period, the yield on high-grade, long-term municipal
bonds fell 1.4 percentage points (from 6.9% to 5.5%). Naturally, the decline in
interest rates has positively affected the share prices of the State Insured
Longer-Term Portfolios. This year has provided exceptionally good performance.

      Specific to the municipal market, the Orange County bankruptcy and the
rumblings of a new Federal "flat tax" structure were pivotal events. First,
Orange County filed for bankruptcy in December of 1994. During the first six
months of 1995, County officials wrestled with several alternatives to "balance
the books." By the end of our fiscal year, the County appeared to be slowly
making progress through budget cuts, revenue sharing agreements, and the
rollover of short-term credit obligations. Ultimately, we expect that Orange
County will emerge from bankruptcy, but the process will be long and is not yet
clearly defined.

      It is important to note again that the Vanguard Portfolios did not and do
not have any direct exposure to Orange County debt. To be sure, this
geographically specific event underscores the advantages of the extra level of
credit protection offered by insured bonds in municipal portfolios.

      In contrast, there is very little protection we can offer against the
seemingly all too frequent changes in tax policy proposed by the various
branches of the Federal government. The latest discussions regarding a flat tax
have aroused great concern throughout the municipal market. A flat tax, if
enacted, will eliminate the current system's progression of increasing marginal
tax rates and replace it with a single lower level for all earned income. This
would require the abandonment of all or most tax deductions, exemptions, and
credits.

      With some proposals, unearned income (interest, dividends, or capital
gains) will not be taxed. Under this scenario, municipal obligations would lose
their unique tax-exempt status. This would reduce the attractiveness of
municipal issues relative to their taxable brethren. Market participants have
already begun to factor in this potential unattractiveness. The yield on
long-term, high-quality municipal bonds has risen from 86.3% of the 30-year
Treasury bond yield at the beginning of the year to 90.2% at the close.
Certainly, it is far too early to forecast the ultimate outcome of the flat tax
legislative proposals, but without the support of the current administration it
is doubtful that any changes will occur prior to the 1996 Presidential
elections. In the meantime, shareholders can enjoy the very attractive
after-tax yield advantage of municipal bonds.

      For the State Insured Portfolios, the past year has held great rewards
for investors who "stayed the course." However, as interest rates have now
returned to historically low levels, we are hesitant to suggest bond prices
will continue on this course through next year. Regardless, investors'
paramount focus should be on long-term objectives. Whatever direction interest
rates move from year to year, Vanguard will continue to combine low expenses
with the conservative management of high-quality Federal and state tax-exempt
portfolios. We believe the outcome is a superior and durable investment.

STATE MONEY MARKET PORTFOLIOS

The beginning of the fiscal year proved to be rocky for the short-term
municipal market. Not long after the Orange County debacle, the Japanese
banking industry came under fire, resulting in the downgrading of several large
Japanese banks. The Daiwa Bank trading scandal further tarnished the reputation
of the Japanese banking industry. We are pleased to report that Vanguard Money
Market Portfolios managed to safely navigate through these





                                       8
<PAGE>   11
murky waters. The Portfolios had no exposure to Orange County notes, nor did we
hold any issues backed by Daiwa Bank.

      Notwithstanding the credit problems overshadowing the municipal money
market, prices on short-term municipals moved higher over the fiscal year. One
area of strength came from a phenomenal rally in the Treasury market. Evidence
of slow growth and low inflation pushed yields on one-year Treasury bills lower
by nearly -1.5% to 5.4% for the fiscal year. Similarly, comparable
high-quality, one-year municipal notes posted a -1.0% decline in yields over
the same period. The Federal Reserve Board intervened two times during the
fiscal year. The first was a tightening of monetary policy, the second an
offsetting easing of policy. Since the close of our fiscal year, signs of
continued economic weakness prompted the Fed to again lower the Federal funds
rate (the rate banks charge each other for overnight loans) 25 basis points to
5.50%.

      Dividends for the Vanguard State Tax-Free Money Market Portfolios bucked
the trend of overall interest rates by moving dramatically higher during the
fiscal year. The average dividend rose more than +40% over this past year. The
impetus for the change came from widening credit spreads for issues supported
by Japanese banks, which led to a rise in average yields for all variable rate
instruments. Variable rate securities, which account for roughly 50% of the
Portfolios' composition, offset the decline in yields experienced in the
broader market and pushed municipal money market yields higher.

      In conclusion, the growing number of risks in the marketplace underscore
the advantage of maintaining high quality standards. Vanguard's conservative
investment style and low expenses combine to provide shareholders with
consistently superior relative returns.

                         NOTES TO FINANCIAL STATEMENTS

Vanguard California Tax-Free Fund is registered under the Investment Company
Act of 1940 as an open-end investment company and consists of the Insured
Long-Term, Insured Intermediate-Term and Money Market Portfolios. Each
Portfolio invests in debt instruments of municipal issuers whose ability to
meet their obligations may be affected by economic and political developments
in the State of California.

A.    The following significant accounting policies are in conformity with
generally accepted accounting principles for investment companies. Such
policies are consistently followed by the Fund in the preparation of financial
statements.

1.    SECURITY VALUATION: Money Market Portfolio: investment securities are
      stated at amortized cost which approximates market value. Other
      Portfolios: municipal bonds are valued utilizing primarily the latest bid
      prices or, if bid prices are not available, on the basis of valuations
      based on a matrix system (which considers such factors as security
      prices, yields, maturities and ratings), both as furnished by an
      independent pricing service.

2.    FEDERAL INCOME TAXES: Each Portfolio of the Fund intends to continue to
      qualify as a regulated investment company and distribute all of its
      income. Accordingly, no provision for Federal income taxes is required in
      the financial statements.

3.    FUTURES: The Insured Long-Term and Insured Intermediate-Term Portfolios
      utilize Municipal Bond Index, U.S. Treasury Bond, and U.S. Treasury Note
      futures contracts to a limited extent, with the objectives of enhancing
      returns, managing interest rate risk, maintaining liquidity, diversifying
      credit risk and minimizing transaction costs. The Portfolios may purchase
      futures contracts instead of municipal bonds when futures contracts are
      believed to be priced more attractively than municipal bonds.  The
      Portfolios may also seek to take advantage of price differences among
      bond market sectors by simultaneously buying futures (or bonds) of one
      market sector and selling futures (or bonds) of another sector. Futures
      contracts may also be used to simulate a fully invested position in the
      underlying bonds while maintaining a cash balance for liquidity.

      The primary risks associated with the use of futures contracts are
      imperfect correlation between changes in market values of bonds held by
      the Portfolios and the prices of futures contracts, and the possibility
      of an illiquid market. Futures contracts are valued based upon their
      quoted daily settlement prices. Fluctuations in the values of futures
      contracts are recorded as unrealized appreciation (depreciation) until
      terminated at which time realized gains (losses) are recognized.
      Unrealized appreciation (depreciation) related to open futures contracts
      is required to be treated as realized gain (loss) for Federal income tax
      purposes.

4.    DISTRIBUTIONS: Distributions from net investment income are declared on a
      daily basis payable on the first business day of the following month.
      Annual distributions from realized gains, if any, are recorded on the
      ex-dividend date. Capital gain distributions are determined on a tax
      basis and may differ from realized capital gains for financial reporting
      purposes due to differences in the timing of realization of gains.

5.    OTHER: Security transactions are accounted for on the date the securities
      are purchased or sold. Costs used in determining realized gains and
      losses on the sale of investment securities are those of specific
      securities sold. Premiums and original issue discounts are amortized and
      accreted, respectively, to interest income over the lives of the
      respective securities.

B.    The Vanguard Group, Inc. furnishes at cost investment advisory, corporate
management, administrative, marketing, and distribution services. The costs of
such services are allocated to the Fund under methods approved by the Board of
Trustees. At November 30, 1995, the Fund had contributed

capital aggregating $285,000 to Vanguard (included in Other Assets),
representing 1.4% of Vanguard's capitalization. The Fund's officers and
trustees are also officers and directors of Vanguard.

C.    The Fund's investment adviser may direct new issue portfolio purchases,
subject to obtaining the best price and execution, to underwriters who have
agreed to rebate or credit to the Fund a portion of the underwriting fees
generated. Such rebates or credits are used solely to reduce the Fund's
administrative expenses. The Fund's custodian bank has also agreed to reduce
its fees when the Fund maintains cash on deposit in the non-interest bearing
custodian account. For the year ended November 30, 1995, directed brokerage and
custodian fee offset arrangements reduced expenses by:

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Shareholders and Board of Trustees
Vanguard California Tax-Free Fund

In our opinion, the accompanying statements of net assets and the related
statements of operations and of changes in net assets and the financial
highlights present fairly, in all material respects, the financial position of
the Insured Long-Term Portfolio, the Insured Intermediate-Term Portfolio and
the Money Market Portfolio (constituting the Vanguard California Tax-Free Fund,
hereafter referred to as the "Fund") at November 30, 1995, and the results of
each of their operations, the changes in each of their net assets and the
financial highlights for each of the respective periods presented, in
conformity with generally accepted accounting principles. 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 generally accepted auditing standards whic h 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 by correspondence with the custodian and brokers and the application
of alternative auditing procedures where confirmations from brokers were not
received, provide a reasonable basis for the opinion expressed above.

ON OUR COVER: On the evening of August 1, 1798, Lord Horatio Nelson sailed his
flagship, HMS Vanguard, into Egypt's Aboukir Bay. In a night encounter,
the British fleet annihilated Napoleon Bonaparte's ships of the line in what is
still considered to be the most complete victory ever recorded in naval
history. Our Report's cover illustration is Thomas Luny's 1830 painting, The
Battle Of The Nile, in which the French flagship, L'Orient, is shown as it
exploded at 10:00 p.m. under a gibbous moon.
