                        A BRAVE NEW WORLD FOR INVESTING

With the clarity of hindsight, we can now see that the past two decades
composed one of the great cycles in the history of the financial markets, as
reflected in the chart below.

* During the 1973-1982 decade, the nominal total returns (capital change plus
income) of stocks and bonds averaged only about +6% per year; cash reserves
averaged more than +8% annually. However, high inflation rates, averaging 8.7%
annually, devastated these nominal results. Real returns (nominal returns less
the inflation rate) for each of these three major asset classes were actually
negative.

* During the 1983-1992 decade, quite the opposite situation prevailed. Nominal
returns for stocks and bonds were close to their highest levels in history and
forged well into double-digit territory. To make a good investment environment
even better, inflation was tame (averaging 3.8% annually), and real returns
were solidly positive.


              [A TALE OF TWO DECADES GRAPH -- SEE EDGAR APPENDIX]


This sharp contrast provides us with perspective for the decade that will end
in the year 2002. Some investors will fear a recurrence of the returns of the
first decade, while others will hope for a recurrence of the second; most will
likely anticipate something in between. Whatever the case, there are two
essential elements involved in considering your investment program in the light
of today's circumstances.

        First, the yield of each investment class at the start of a decade has
had an important relationship to its future return. Yields were low when
1973 began, high when 1983 began, and are again low today. In fact, current
income yields are remarkably close to the levels of 20 years ago, as shown
in the following table.

But there is a second important element to consider: inflation. It got
progressively worse during most of the first decade, but got progressively
better in the second.

CHAIRMAN'S LETTER

FELLOW SHAREHOLDER:

The decline in interest rates continued--and indeed accelerated--during the
twelve months ended November 30, 1993, the eighth fiscal year of the Vanguard
State Tax-Free Funds. Lower yields pushed the prices of long-term tax-exempt
bonds higher, and the net asset values of our Insured Long-Term Portfolios
benefited accordingly. As rates fell, however, interest income was reduced,
with the most immediate impact felt in our Money Market Portfolios.
        Reflecting the low-interest-rate environment that prevailed over the    
past twelve months, our Money Market Portfolios provided returns that were
modest in an absolute sense, albeit comfortably above the returns of their
respective competitive benchmarks. The total returns (capital change plus
income) of our Insured Long-Term Portfolios were exemplary, surpassing even the
excellent results that we achieved in our prior fiscal year. It is difficult to
imagine a more beneficial two-year stretch for investors in long-term bonds. In
any event, here are the Portfolio highlights for the past twelve months:

* THE STATE MONEY MARKET PORTFOLIOS--
provided total returns of about +2.4% . . . with declining money market
rates for yet another year, Portfolio yields ended the period at lower levels
than where they began, hovering in the area of 2.3% . . . net asset values, of
course, remained at $1.00 per share. 

* THE STATE INSURED LONG-TERM PORTFOLIOS-- enjoyed another outstanding year
"across the board," as each Portfolio turned in a double-digit return ranging
from +12% to +13% . . . current yields are at their lowest levels in our Funds'
(admittedly rather short) history.      
        The detailed results for each of our State Tax-Free Portfolios,
including per share net asset values, dividends and capital gains distributions
for the fiscal year, as well as current yields are presented at the end of this
letter. The following table summarizes the returns for our State Insured
Long-Term Portfolios:

</TABLE>
In last year's Annual Report, I called special attention to the substantial
capital component (appreciation in net asset value per share) of the total
returns on our State Insured Long-Term Portfolios. My purpose in doing so at
that time was to advise investors that it seemed unreasonable to expect a
recurrence of these capital returns in fiscal 1993. As shown in the table, this
year the role of capital appreciation in our Portfolios' results turned out to
be even more dramatic, accounting on balance for some 50% of our total returns.
                                                                     (continued)

<PAGE>   4

                 [MONTH-END YIELDS GRAPH -- See Edgar Appendix]

        Although my cautionary words one year ago could hardly have been further
off the mark, I nonetheless would remind shareholders that capital returns of
the magnitude shown in the preceding table simply cannot be taken for granted.
Indeed, with long-term interest rates at their lowest levels in two decades,
now is a perfect opportunity to remind investors that, should rates reverse
direction and move higher "capital reward" will inevitably translate to "capital
penalty" for each of our six Insured Long-Term Portfolios.

        The excellent absolute returns for all of our Insured Long-Term
Portfolios in fiscal 1993 come on top of the double-digit returns earned in the
prior fiscal year. The chart at the top of the facing page illustrates the
results of the Pennsylvania Insured Long-Term Portfolio since its inception in
April 1986, compared with the results of the two most appropriate available
benchmarks: the unmanaged Lehman Municipal Bond Index and the average
Pennsylvania insured municipal fund.  You can see that our long-term return has
been somewhat better than that of the average competitor, and matched that of
the unmanaged Index. I should also note that the Pennsylvania Money Market
Portfolio has achieved respectable results since its inception in June 1988,
achieving a cumulative return of +27.0% versus +27.2% for its average competitor
(+4.5% versus +4.5% annually).

* THE FISCAL YEAR IN REVIEW
Our 1993 fiscal year was the sixth consecutive year of favorable markets--and
the third consecutive year of double-digit returns--for long-term bonds. Lower
yields drove up the prices of municipal, corporate, and U.S. Treasury bonds
alike. Treasury bonds registered the largest rate declines and garnered the
greatest price appreciation, gaining some +17% for the year. Over the same
period, yields on high- grade, long-term, tax-exempt bonds fell 0.70% (70
"basis points"), from 6.2% to 5.5%, resulting in a price increase of +10%.

        Compared to the sharp decline in long-term rates over the past twelve
months, the drop in short-term tax-exempt rates was fairly muted. From the 2.7%
level at the outset of the fiscal year, yields on high-grade (MIG 1) municipal
notes fell to 2.0% in January 1993, climbed to 2.6% at the end of July, and
closed the year at 2.4%.        

        The consensus holds that the rate decline is based on two fundamental
factors. First, the U.S. economy remains sluggish, unable to provide the typical
post- recession snapback that investors have come to expect. Second, and perhaps
more importantly, there is continuing evidence that inflation remains well under
control.  The U.S. consumer price index (CPI) increased 2.7% over the past
twelve months, compared to 3.0% during the prior twelve-month period. As a
result, despite the sharp decline in interest rates, "real" yields (nominal
yields less the inflation rate) on long-term bonds remain at healthy levels. The
chart to the left provides a striking illustration of how precipitous the
decline in interest





                                       2

<PAGE>   5
              [CUMULATIVE PERFORMANCE GRAPH -- SEE EDGAR APPENDIX]

rates has been over the past four years, with nearly all of the decline coming
during the final three years. The yield on high-grade, long-term municipal
bonds fell from 7.0% on November 30, 1989, to 5.5% on November 30, 1993. For
short-term tax-exempt rates, the decline during the same period was more
pronounced, with the yield on high-grade notes falling on balance from 5.9% to
2.4%. As a result of this disparity in rate declines, the "spread" of the long
rate over the short rate has widened from 110 basis points at the beginning of
the period to 310 basis points at the end. This widening reflects a very
"steep" yield curve, allowing fixed-income investors to earn a substantial
income premium by extending the maturity of their bond holdings. It should go
without saying that each step out in length of maturity brings with it
additional price volatility.

* THE ADVANTAGE OF TAX-EXEMPT INCOME
In each year's Annual Report, we present our customary table illustrating the
advantage of tax-exempt investments versus taxable investments, after adjusting
for the effect of Federal taxes at the maximum marginal rate on income
payments. Here are the results of the comparison at the end of fiscal 1993:

Table assumes current yields (as of November 30, 1993) of 6.3% for U.S.
Treasury bonds, 3.2% for Treasury bills, 5.5% for long-term municipals, and
2.4% for short-term municipals. The illustration is not intended to represent
future results.

The advantage spelled out in the table--a 45% increase in after-tax income for
the long-term investor and a 26% increase for the short-term investor--strongly
suggests that investors who are taxed at the highest marginal rates should
consider tax- exempt alternatives for the fixed-income





                                       3

<PAGE>   6
portion of their overall investment portfolio. (I should add that both the
interest earned on our State Tax-Free Portfolios and the interest earned on
U.S. Treasury obligations are exempt from taxes at the state level.)
        As I noted earlier, the decline in yields on U.S. Treasury bonds has
been significantly larger than that on tax-exempt bonds. This divergence is
paradoxical considering that it comes just as the maximum marginal federal tax
rate has been raised from 31% to 39.6%--the highest rate since 1986. This       
should mean that the spread between taxable and tax-exempt rates would widen;
instead, it has narrowed for long-term investors and remained about the same for
short-term investors.
        To be sure, even the highest quality insured state municipal bond cannot
quite match the creditworthiness of a U.S. Treasury bond, and long-term
municipal bonds are usually callable after 10 years, a disadvantage not shared
by Treasury securities.  So, the yield comparison has a moderate structural bias
in favor of municipals. But the yield differential illustrated in the table is
hardly "moderate"--it is more like "day and night." Suffice it to say that the
ability of top-tax-bracket investors to earn substantially more after-tax income
with only a marginal sacrifice in quality is unlikely to persist indefinitely.
It is probably fair to say that relative values in tax-exempt bonds are as great
on a sustained basis as they have been for two decades. 

* A PERSPECTIVE ON TODAY'S INTEREST RATE ENVIRONMENT
The aggregate assets of all municipal bond mutual funds now total some $350
billion, and the funds are now among the largest buyers and holders of
tax-exempt securities.  While, like all mutual funds, our State Insured
Tax-Free Portfolios promise "liquidity on demand" to shareholders, it must be
clear that providing this liquidity depends to a degree on an orderly
liquidation pattern by investors. With the exception of the industry's
experience during 1987's sharp dip in long-term bond prices, resulting from the
upward spikes in interest rates in April and May of that year, the industry's
handling of redemptions has been flawless, and daily liquidity has been
maintained without impacting the marketplace. (Given the very short maturities
of money market instruments, liquidity is much less of a concern in our State
Money Market Portfolios.)
        And yet, with rates having come down so far and so fast, there is always
the risk of a sharp rebound. When that happens, investors who have purchased
municipal bond funds for the long term should not be concerned. However, there
appears to be an active body of short-term speculators who move their money from
long-term to short- term bonds at the proverbial drop of a hat. You should know
that at Vanguard we do our best to exclude these speculators from our funds, by
rigorously limiting the frequency of inter-fund exchanges and by refusing to
accept business from known "market timers."
        If you are an investor who likes to speculate on interest rate changes,
I urge you to move your assets to one of our many competent competitors. If you
are an investor who will respond with fright to any kind of reversal of the past
five year's rise in bond prices, I urge you to shorten your maturity profile by,
for example, moving a portion of your assets from the more volatile Insured
Long-Term Portfolio for your state to our corresponding Money Market Portfolio
(available in all states but New York and Florida, in which case the Money
Market Portfolio of Vanguard Municipal Bond Fund might be selected). If you are
a long-term investor--content that your needs for capital stability (with
commensurate income volatility) in our Money Market Portfolios and for income
stability (with commensurate capital volatility) in our Insured Long-Term
Portfolios are being met--I urge you, once again, to "stay the course."

* IN SUMMARY
As I write this letter, the combined assets of the ten Vanguard State Tax-Free
Portfolios are approaching the $8 billion mark, up some 30% in just one year.
This staggering growth is a testament, we believe, to an ever-increasing
understanding among investors





                                       4

<PAGE>   7
that, all else being equal, costs will "carry the day." With the yield on the
average state tax-exempt bond fund at 4.3%, and with 102 of 137 state
tax-exempt money market funds now yielding less than 2.0%, costs will be an
even more critical determinant of the top-performing funds.
        This is precisely the kind of environment in which the Vanguard State
Tax-Free Portfolios should thrive. While the average competitive state tax-free
portfolio charges annual fees at the rate of 0.68% of average net assets, the
expense ratio for our Portfolios, at 0.21%, is just a fraction of this amount.
For a money market portfolio with a gross yield of 2.0%, the expenses of the
average competitor would consume nearly 35% of its interest income; Vanguard's
expenses would consume but 11%. It is hard to imagine that intelligent investors
could be attracted to a fund with such a built-in yield disadvantage.
        In closing, we believe that, whatever the future course of interest
rates, our State Tax-Free Portfolios will provide returns that generally exceed
those of their respective competitors.

Sincerely,

A WORD ABOUT CAPITAL GAINS DISTRIBUTIONS
You may recall that, during the rising bond markets of each of the past three
years, some of our Insured Long-Term Portfolios realized modest capital gains.
And, it will probably not surprise you to know that each Portfolio realized
capital gains in 1993. These amounts must, under Federal tax regulations, be
distributed to shareholders of our Portfolios as taxable capital gains.
        I want to emphasize that it is not our objective to realize capital
gains; rather, these gains are a by-product of a number of factors, including,
most importantly, sharply rising municipal bond prices, bonds that are called or
refunded, and limited portfolio strategy shifts to capitalize on the relative
valuations of different market sectors.

These data represent past performance. The investment return and principal
value of an investment will fluctuate so that an investor's shares, when
redeemed, may be worth more or less than their original cost.

Please note that an investment in a money market fund, such as the Money Market
Portfolio of Vanguard Pennsylvania Tax-Free Fund, is neither insured nor
guaranteed by the U.S. Government, and there is no assurance that the Fund will
be able to maintain a stable net asset value of $1.00 per share.

REPORT FROM THE INVESTMENT ADVISER
STATE INSURED LONG-TERM PORTFOLIOS

* TIME FOR CHANGE?
Just one year ago, President Clinton was elected on a platform of change. Since
that time, the restrictive economic impact of higher taxes has overshadowed the
relatively quiet role played by Federal Reserve policy, and long-term interest
rates have declined precipitously. For the fiscal year ended November 30, 1993,
the yield on the 30-year U.S. Treasury Bond fell 1.2 percentage points (from
7.5% to 6.3%).  During the same period, high-grade, long-term municipal yields
fell nearly three- quarters of a percentage point, from 6.2% to 5.5%.

     The net result was another year of good performance both for the State
Insured Long- Term Portfolios and the bond market as a whole. In light of the
many successive years of above-average returns by longer-maturity fixed-income
investments, one has to wonder how much longer the rally can last.

* MUNICIPAL BONDS ARE ATTRACTIVE VERSUS TAXABLE BONDS
While municipal bond prices have risen sharply, taxable bond prices have
rallied even more. High-grade tax-exempt bonds currently provide 86% of the
yield on the 30- year U.S. Treasury bond, up from 82% at the beginning of the
year. This "cheapening" has been due primarily to a huge increase in the pace
of municipal bond issuance.  Indeed, 1993 municipal supply set an all-time
record of some $290 billion--fully 25% above the previous record set just last
year, and easily twice the volume of a typical year's issuance.

        Municipalities of all types have flooded the marketplace to refinance
higher cost debt at today's lower yield levels. We believe this process has run
full course, and suggest that municipal bonds are extremely attractive when
compared to their taxable brethren. The case for municipal bonds is even more
compelling in light of recently increased marginal tax rates.

* INVESTMENT STRATEGY
Given the current environment, the State Insured Long-Term Bond Portfolios are
pursuing the following investment strategies:

 * CALL PROTECTION. We continue to emphasize call protection in all of our
longer bond portfolios. This strategy has produced greater price appreciation
as yields have declined. Importantly, it also will insulate future dividends
from an abrupt decline due to bond calls.

 * MUNICIPAL VERSUS TREASURY. We have positioned the Portfolios to take
advantage of the exceptionally cheap relationship of municipal bonds versus
Treasury bonds. This positioning has been accomplished by simultaneously
establishing long positions in municipal bond futures contracts and short
positions in Treasury bond futures contracts. Although this strategy has
slightly detracted from annual performance thus far, we believe it will produce
positive results in 1994.

 * "LONG AND RIGHT." Over the past few years, the State Insured Long-Term
Portfolios have maintained a longer maturity structure and consequently a
higher sensitivity to changes in interest rates than our competitors. This
strategy has served us well and produced good longer-term results in a
substantial bull market for fixed-income securities. During the course of the
past year, we reduced somewhat our longer maturity structure to match that of
our competitors, thereby "locking in" gains earned to date.

        In conclusion, the past twelve months has been an exciting period for
bond fund shareholders. Plummeting interest rates have translated into
attractive performance returns on long-term, tax-exempt fixed-income
investments. To be sure, this will be a tough standard to surpass.
                                                                     (continued)

STATE MONEY MARKET PORTFOLIOS

Over the past twelve months, moderate economic expansion and low inflation
enabled the Federal Reserve Board to hold key interest rates steady. The last
policy action taken by the Fed occurred in early September 1992, when it
lowered the Federal funds rate to 3%.

        Despite the overall stability in short-term rates, yields on tax-exempt
money market funds continued to decline. Plagued by a combination of sporadic
supply and strong investor demand, yields on state-specific money funds
deteriorated 30 basis points, from 2.2% to 1.9%. Notwithstanding this yield
decline, assets grew at a robust 14% rate. Strong performance versus the
competition, due primarily to Vanguard's expense ratio advantage, enabled our
money market funds to capture a large percentage of these assets. 

        The volume of new issue supply differed greatly among the various
state-specific funds. Recessionary and fiscal stress, which has persisted in
California, forced many of its municipalities to finance their cash needs with
short-term debt. As a result, July and August brought a flood of supply in
California tax-exempt paper. At the opposite end of the spectrum was New Jersey,
where diminished supply was attributable primarily to relatively low long-term
interest rates. The many municipalities that previously issued short-term notes
took advantage of these low rates by issuing long-term bonds instead. 

        Looking forward, net new issuance in the first quarter of fiscal year
1994 is expected to remain light. Poised for this anticipated drought in supply,
the Vanguard State Tax-Free Money Market Portfolios are currently targeting a
minimum average weighted maturity of 75 days. Beyond the first quarter we will
proceed with caution, as any signs of increased inflation may prompt the Federal
Reserve Board to raise short-term interest rates.

NOTES TO FINANCIAL STATEMENTS
Vanguard Pennsylvania 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 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 Commonwealth of
Pennsylvania.

* 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. Insured Long-Term
Portfolio: 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 Portfolio may utilize futures contracts to a
limited extent. The primary risks associated with the use of futures contracts
are imperfect correlation between the change in market value of the bonds held
by the Portfolio 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 value 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.  The Fund has contributed capital aggregating $394,000 to Vanguard
(included in Other Assets), representing 2.0% of Vanguard's capitalization. The
Fund's officers and trustees are also officers and directors of Vanguard.

* C. During the year ended November 30, 1993, the Insured Long-Term Portfolio 
made purchases of $473,310,000 and sales of $173,694,000 of investment 
securities other than temporary cash investments.

At November 30, 1993, unrealized appreciation of investment securities of the
Insured Long-Term Portfolio for financial reporting and Federal income tax
purposes aggregated $111,887,000 of which $112,275,000 related to appreciated
securities and $388,000 related to depreciated securities.

* D. At November 30, 1993, the Insured Long-Term Portfolio had long positions in
Municipal Bond Index futures contracts expiring through March, 1994, with an
aggregate settlement value and net unrealized depreciation of $28,937,000 and
$320,000, respectively. The aggregate settlement value and net unrealized
appreciation related to short positions in U.S. Treasury Bond and U.S. Treasury
Note futures contracts expiring through March, 1994, were $179,563,000 and
$2,144,000, respectively. The market value of securities deposited as initial
margin for open futures contracts was $2,544,000.

REPORT OF INDEPENDENT ACCOUNTANTS

To the Shareholders and Board of Trustees
Vanguard Pennsylvania 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 and the Money Market Portfolio (constituting
the Vanguard Pennsylvania Tax-Free Fund, hereafter referred to as the "Fund")
at November 30, 1993, 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 which
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.

(Continued from inside front cover)
toward those of the 1970s. However, the current level of inflation suggests
that future real returns may prove to be satisfactory. Looking forward, the
main risks to the investor are two: (1) that yields on financial assets will
rise sharply, reducing the prices of stocks and bonds alike; and (2) that
inflation, presently at moderate levels, will accelerate.

SOME COURSES OF ACTION
What, if any, present action should be taken by investors to deal with
these two major risks? Should your allocation of assets among stock funds, bond
funds, and money market funds be adjusted? Here are some reasonable courses of
action to consider:

* For long-term investors who have built a substantial balanced
    portfolio of stock, bond, and money market funds, stay the course. Even if
    withdrawing from the stock market proves to be justified, the next
    decision--when to return--will one day be required. "Being right twice" is
    no mean challenge.

* For long-term investors gradually accumulating assets for, say,
    retirement, stay your present course. Continue to invest regularly. By
    doing so, you buy more shares of a mutual fund when its price falls, and
    fewer shares when its price rises, virtually assuring a reasonable average
    cost.

* For risk-averse investors who are highly confident that stock prices are
    "too high," make only marginal--not "all or nothing"--changes in
    your portfolio balance.  Given the perils of predicting the future, any
    changes should be limited to, say, 15 percentage points. That is, if your
    normal portfolio allocation is 60% in stock funds, it might be reduced to
    45%; if 85%, to 70%.

* For investors who simply must have more income, never lose sight of
    the added principal risk involved in shifting from money market funds to
    bond funds. Long-term bond funds provide a generous and durable income
    stream, but their prices are highly volatile. Short-term and
    intermediate-term bond funds offer a "middle way" of increasing income with
    more modest risk to principal.

* For investors who are tempted to find an "easy way" to higher returns,
    never forget that risk and reward go hand in hand. Precipitously
    replacing certificates of deposit with broad-based common stock funds
    verges on the irrational. Funds investing in other securities
    markets--emerging nations, international stocks and bonds, and small U.S.
    companies--carry their own special risks. Generally, limit such alternative
    investments to, say, 20% of your total portfolio.

For all investors, be prepared for sharp interim swings in stock and
bond prices.  The central tenet of investing is "prices fluctuate," and
sensible long-term investors simply must take such fluctuations in their
stride. Successful investing is as much a function of your own discipline and
equanimity as it is of the returns available in the securities markets.

THREE ESSENTIAL PRINCIPLES
As we confront the brave new world of investing that may well lie ahead in the
coming decade--and it is important to think in decade-length terms--we would
underscore three caveats:

1. Have "rational expectations" for future returns. At prices   
    prevailing today, it seems highly unlikely that the returns enjoyed by
    investors in the past decade will be repeated in the coming decade.

2. Maintain a balanced portfolio consisting of stock, bond, and money
    market funds.  Each asset class has its own risk and reward
    characteristics. By allocating your resources among the three asset classes
    according to your own requirements, you can build a portfolio providing
    appropriate elements of capital appreciation, capital conservation, and
    current income.

3. In balancing risk against reward, be sure to consider cost. Many mutual      
    funds carry hefty sales charges or high expense ratios, or both. Other
    factors held equal, expenses reduce returns, dollar for dollar. Put another
    way, high-cost funds must select investments with higher prospective gross
    returns--which entail higher risks- -to match the net returns earned by
    low-cost funds.

This brief Annual Report essay can provide only an elementary look at the
challenges investors face today. History can give us perspective, but it cannot
give us performance. Famed British economist Lord Keynes had it right when he
said, "the inevitable never happens. It is the unexpected always."
