Prudential Municipal Bond Fund--High Income Series

Peter J. Allegrini
Fund Manager

Investment Goals and Style
We seek the maximum amount of income that is eligible for exclusion from
federal income taxes by investing primarily in noninvestment-grade municipal
bonds rated single-B or better by recognized credit-rating agencies such as
Standard & Poor's Ratings Group (S&P) or Moody's Investors Service (Moody's),
or in unrated bonds that our analysts believe are of comparable quality. On
April 30, 1999, noninvestment-grade municipal bonds rated BB or below (or
unrated bonds of comparable quality) comprised approximately 47% of the
portfolio, compared with about 56% on April 30, 1998. There can be no assurance
that the Series will achieve its investment objective.

Market Review
A narrow range
For most of the past year, the difference between high-yielding bonds that
performed well and those that performed poorly was minimal. We were able to add
bonds to your Series that produced higher-than-average yields, as compared to
our competitive universe, which helped returns. However, we unfortunately
purchased certain bonds that had credit problems, and that took away from the
returns on your Series--particularly bonds of the Graduate Hospital of PA; the
city of Robbins, IL; and Great Lakes Pulp and Fiber. These purchases--coupled
with a strong U.S. economy that we expected to slow--and the Series'
longer-than-average duration stance contributed to your Prudential Municipal
Bond Fund--High Income Series gaining 4.96% for Class A shares, compared to
5.27% for the Lipper Average High Yield Municipal Fund.

Market volatility
When the economic crisis that began in Asia in early 1998 spread to Russia and
eventually to Brazil, investors demanded quality investments for their money.
Concerned that the crisis would eventually slow the U.S. economy, investors
began investing their money in "safe haven" securities such as U.S. Treasuries.
This trend also drove prices of insured municipal bonds higher and their yields
lower. Your Series benefited since it held some of these securities. Then in
the fall of 1998, in an effort to stabilize the global economic situation and
improve investor confidence, the Federal Reserve cut interest rates on three
separate occasions. The Series initially benefited from these rate cuts as bond
yields fell even lower and their prices went higher.

Our fundamentals were solid
We anticipated, as did much of the market, that interest rates would fall
throughout 1998 as the global financial crisis spread. We positioned the Series
with a neutral average duration stance, as compared to our competitive
universe, from the spring of 1998 through October 1998, since we expected the
U.S. economy to slow. Duration is a measure of sensitivity to interest-rate
changes. A neutral duration stance makes it easier for the Series to lengthen
or shorten its duration when necessary. At this time, we felt investors would
be looking for safety, therefore we added bonds to your Series that were
higher-rated credits and cut back on our below-investment-grade bonds. In
hindsight, we did not hold as many New York state and California state
municipal bonds as we should have. These particular state bonds performed

extremely well during the summer and early fall of 1998, and would have added
to the Series' return had we held more of them.

The Fed cut rates and we moved
In the fall of 1998, when the Federal Reserve made its first of three
interest-rate cuts, we sought to lengthen our average duration on the Series. A
longer duration stance enables the Series to perform well when debt markets
rally. The debt market rally hit its peak when the Bond Buyer Index fell to
5.09% in early October--its lowest yield since the Index was compiled. To
extend duration, we bought noncallable municipal bonds since they cannot be
retired by the issuer prior to maturity. Furthermore, a portion of these bonds
were zero coupon bonds that are issued at a deep discount and redeemed at face
value when held to maturity. The difference between the discounted price and
the face value of the bond represents accrued interest. Since zero coupon bonds
trade at such sharp discounts to their face value, their prices had plenty of
room to rise as the tax-exempt market rallied. We were able to lock in current
yields on these bonds before their yields went lower. In the short term, the
Series benefited from this strategy.

The market stabilizes
The Federal Reserve's three interest-rate cuts accomplished what they set out
to do: stabilize the global financial crisis and improve investor confidence.
However, this eventually hurt our Series' performance as investors shifted
their money from the safety of U.S. Treasuries back into riskier investments.
Yields on municipal bonds began to rise again, and their prices began to fall.
Particularly hard hit were noncallable bonds and zero coupon bonds, whose
prices fell significantly. These bonds don't perform well when debt markets
sell off, as they began to do here. Moreover, we held long-term noncallable
bonds with 15- to 20-year yields. Bonds on that part of the yield curve
particularly did not perform well. The Series was hurt by its structure, since
our longer duration stance, which helped our returns in the early fall of
1998, hurt our returns as 1999 began.

Resiliency
As the first quarter of 1999 progressed, we thought that the U.S. economy would
slow down, feeling the aftereffects of the global financial crisis. Under this
scenario, investors within the market would fly to high-quality insured
investments. Therefore the Series kept its duration stance longer than its
competitive universe so the Series would benefit when debt markets rallied
once again. However, this scenario did not take place, as the U.S. economy
remained very resilient and actually grew at a strong pace. Investors sold off
U.S. Treasuries, and municipal bonds suffered as their prices plummeted.
Maintaining the Series' longer duration stance in the first few months of 1999
took away from our returns. Basically, what worked well for us in the fourth
quarter of 1998 did not work well in the first quarter of 1999.

Looking Ahead
Since the U.S. economy remains strong and fear of higher inflation is growing,
the Federal Reserve has announced that it is leaning toward raising interest
rates in the future. This announcement should eventually stabilize and benefit
the bond markets. Therefore we will position the Series with a neutral average
duration stance, as compared to our competitive universe, until we see a
definite move by the Fed. This will enable us to move quickly in the right
direction when the market dictates. Furthermore, we will look to add both New
York state and California state municipal bonds--as well as bonds from other
states with strong economies--to the Series' holdings since they should
continue to perform well, will improve the Series' credit rating, and will
bolster returns.

cumulative total returns do not take into account sales charges. The average
annual total returns do take into account applicable sales charges. The Series
charges a maximum front-end sales charge of 3% for Class A shares. Class B
shares are subject to a declining contingent deferred sales charge (CDSC) of
5%, 4%, 3%, 2%, 1%, and 1% for six years. Class B shares will automatically
convert to Class A shares, on a quarterly basis, approximately seven years
after purchase. Class C shares are subject to a front-end sales charge of 1%

have a 1% CDSC if sold within one year. Class Z shares are not subject to a

Prudential Municipal Bond Fund--Insured Series
- -------------------------------------------------------------------------------
(PHOTO)

Christian Smith
Fund Manager

Investment Goals and Style
The Insured Series invests primarilyin AAA-rated municipal obligations or in
municipal obligations whose timely coupon and principal payments (but not
market value) are insured by a municipal bond insurance company rated AAA by
S&P, Moody's, or other nationally recognized credit-rating agencies. The Series
may also invest up to 5% of its total assets in municipal obligations rated A/A
or Aa/AA by Moody's or S&P. There can be no assurance that the Series will
achieve its investment objective.

Our bonds are primarily insured by MBIA Insurance Corp., AMBAC Indemnity Corp.,
Financial Guaranty Insurance Co., and Financial Security Assurance Inc.

Market Review
Investors sought quality
Demand continued for AAA-rated insured municipal bonds throughout most of the
reporting period amid concerns that the global financial crisis would spread to
the U.S. economy. In this environment, insured bonds performed better than
lower-quality securities, and your Prudential Municipal Bond Fund--Insured
Series outperformed the Lipper Average Insured Municipal Fund during the year
ended April 30, 1999.

We positioned the Series correctly
Throughout the spring and early summer of 1998, concerns about the global
financial crisis became more prevalent, but the U.S. economy continued to grow
at a rapid pace. However, by August, the financial crisis that began in Asia
spread to Russia, and eventually to Brazil. Fearing the financial contagion
would spread to the United States, investors created a "flight to quality" by
investing their money in "safe haven" securities such as U.S. Treasuries and
municipal insured bonds. Within the tax-exempt market, insured bonds tend to
perform better when the economy slumps than lower-quality securities. This
"flight to quality" drove the prices of municipal bonds higher, their yields
lower and, therefore, your Series' return higher as well. In anticipation that
interest rates would decline as the year progressed, we increased your Series'
duration from 7.6 years in April 1998 to 8.4 years in October 1998. This was a
longer-than-average duration stance compared to its competitive universe.
Duration is a measure of sensitivity to interest rate changes. A longer average
duration enables shares of the Series to rise more rapidly when interest rates
fall.

We were able to achieve this longer duration stance by adding noncallable bonds
to the Series throughout the year. The Series increased its holdings in
noncallable bonds to 42% of its portfolio as of April 30, 1999. Noncallable
bond prices soared when interest rates began to decline because these bonds
cannot be retired prior to maturity. Therefore noncallable bonds are very
attractive during a bond market rally. Moreover, a portion of our noncallable
bond holdings were zero coupon bonds.

Past performance is not indicative of future results. Principal and investment
return will fluctuate so that an investor's shares, when redeemed, may be worth
more or less than their original cost.

cumulative total returns do not take into account sales charges. The average
annual total returns do take into account applicable sales charges. The Series
charges a maximum front-end sales charge of 3% for Class A shares. Class B
shares are subject to a declining contingent deferred sales charge (CDSC) of
5%, 4%, 3%, 2%, 1%, and 1% for six years. Class B shares will automatically
convert to Class A shares, on a quarterly basis, approximately seven years
after purchase. Class C shares are subject to a front-end sales charge of 1%
and a CDSC of 1% for 18 months. Class C shares bought before November 2, 1998,
have a 1% CDSC if sold within one year. Class Z shares are not subject to a
sales charge or distribution fee. Without waiver of management fees and/or
expense subsidization, the Series' cumulative and average annual total returns
would have been lower, as indicated in parentheses ( ).

Insured Series Cont'd.
- -------------------------------------------------------------------------------

These bonds perform well when debt markets rally since they generally trade at
deep discounts to their face value at maturity. Furthermore, the difference
between the discounted price and the face value of the bond represents accrued
interest, and because zero coupon bonds trade at such sharp discounts to their
face value, their prices had plenty of room to rise. Your Series benefited
greatly from this strategy as we were able to anticipate the market's movements
correctly.

The Federal Reserve intervened
To stabilize the global financial crisis and improve investor confidence, the
Federal Reserve cut the Federal funds rate (the rate banks charge each other to
borrow money overnight) three times in the fall of 1998 by a quarter of a
percentage point each time. As investors felt more confident, the "flight to
quality" reversed, and investors began to move their money back into riskier
investments and away from the safety of U.S. Treasuries and municipal insured
bonds. This trend sent prices of municipal insured bonds lower and their yields
higher. These interest-rate cuts initially helped the returns on our Series;
however, with the global markets now stabilizing and the U.S. economy
continuing to experience strong growth, interest rates began to rise again, and
the Series' longer duration stance modestly hurt performance.

U.S. economy remained resilient
Even though the Federal Reserve stabilized the global financial markets and
drove investor confidence higher, we thought it would not have a lasting
effect, and that U.S. economic growth would eventually succumb to global
financial pressures and experience a slowdown. However, at the beginning of
1999, the U.S. economy was very resilient and did not slow, but actually
experienced further growth. Furthermore, with long-term interest rates rising
again, prices of municipal bonds fell--particularly prices of noncallable bonds
and zero coupon bonds. We did shorten the average duration of your Series from
8.4 years back to 7.6 years during the latter part of the first quarter of
1999. However, we began implementing this strategy later than we should have
and, as a result, gave back some of the gains the Series experienced during the
year. Overall, the Series' duration stance ended the reporting period where it
began--at 7.6 years.

A neutral position going forward
Even though the U.S. economy remains strong, the Federal Reserve has announced
that it is leaning toward raising interest rates in the future to quell
inflationary fears. We anticipate this move will eventually stabilize and
benefit the bond markets. Therefore we will position the Series with a neutral
duration stance, as compared to our competitive universe, until we see a
definite move by the Fed.

A Message to Our Shareholders                                     June 18, 1999
- -------------------------------------------------------------------------------
(PHOTO)

Dear Shareholder:
In the last couple of years, the recurring possibility of a global economic
crisis caused investors to focus on securities they perceived to be safe. In
the equity market, they focused on the stocks of a handful of very large
companies that were perceived to be well-buffeted from an economic slowdown.
These stocks became very expensive--out of proportion to their earnings
expectations. As a result, there was a substantial disparity in value between
large and small companies and between growth and value stocks.

Since earlier this year, however, that gap has narrowed significantly amid
news of strong U.S. economic growth and faster-than-expected global stability.
While the long-term prospects of U.S. growth stocks are still very good, many
of the smaller and economically sensitive companies favored by our value
managers now are posting very attractive returns.

In the bond market, U.S. Treasuries and select European government bonds were
the major beneficiaries of the flight to quality that occurred in recent years.
When this trend reversed itself toward the end of 1998, other sectors of the
bond market rebounded. However, with a strong U.S. economy comes the threat of
higher inflation, which erodes the value of bonds' fixed interest payments.
The recent inflation concerns jolted the bond market and helped send long-term
interest rates to a 19-month high.

The winds of change in the equity market and the recent turbulence in the bond
market not only highlight the value of professional portfolio management, they
illustrate why investors should have a well-diversified asset allocation
strategy. It is also a good practice to rebalance your holdings, when
necessary, to keep your asset allocation consistent with your long-term
objectives and risk tolerance. A properly diversified portfolio of value- and
growth-oriented equity funds, international bond funds, and money market funds
could help you weather inevitable market turbulence and achieve more consistent
returns over time. Prudential offers a wide range of mutual funds to help our
shareholders diversify, as well as several balanced and diversified funds to
allow one-decision diversification.

Thank you for your continued confidence in Prudential mutual funds.

Sincerely,

John R. Strangfeld

Notes to Financial Statements                    PRUDENTIAL MUNICIPAL BOND FUND
- --------------------------------------------------------------------------------
Prudential Municipal Bond Fund (the 'Fund') is registered under the Investment
Company Act of 1940 as a diversified, open-end management investment company.
The Fund was organized as an unincorporated business trust in Massachusetts on
November 3, 1986 and consists of two series: the High Income Series and the
Insured Series. Investment operations for Class A, Class B, Class C and Class Z
shares of each series commenced on January 22, 1990, September 17, 1987, August
1, 1994 and September 16, 1996, respectively.
The investment objectives of the series are as follows: (i) the objective of the
High Income Series is to provide the maximum amount of income that is eligible
for exclusion from federal income taxes, (ii) the objective of the Insured
Series is to provide the maximum amount of income that is eligible for exclusion
from federal income taxes consistent with the preservation of capital. The
ability of issuers of debt securities held by the Fund to meet their obligations
may be affected by economic and political developments in a specific state,
region or industry.
- ------------------------------------------------------------
Note 1. Accounting Policies
Securities Valuation: Municipal securities (including commitments to purchase
such securities on a 'when-issued' basis) are valued on the basis of prices
provided by a pricing service which uses information with respect to
transactions in bonds, quotations from bond dealers, market transactions in
comparable securities and various relationships between securities in
determining values. If market quotations are not readily available from such
pricing service, a security is valued at its fair value as determined under
procedures established by the Trustees.
Short-term securities which mature in more than 60 days are valued at current
market quotations. Short-term securities which mature in 60 days or less are
valued at amortized cost.
Financial Futures Contracts: A financial futures contract is an agreement to
purchase (long) or sell (short) an agreed amount of debt securities at a set
price for delivery on a future date. Upon entering into a financial futures
contract, the Fund is required to pledge to the broker an amount of cash and/or
other assets equal to a certain percentage of the contract amount. This amount
is known as the 'initial margin.' Subsequent payments, known as 'variation
margin,' are made or received by the Fund each day, depending on the daily
fluctuations in the value of the underlying security. Such variation margin is
recorded for financial statement purposes on a daily basis as unrealized gain or
loss. When the contract expires or is closed, the gain or loss is realized and
is presented in the statement of operations as net realized gain (loss) on
financial futures contracts.
The Fund invests in financial futures contracts in order to hedge its existing
portfolio securities, or securities the Fund intends to purchase, against
fluctuations in value caused by changes in prevailing interest rates. Should
interest rates move unexpectedly, the Fund may not achieve the anticipated
benefits of the financial futures contracts and may realize a loss. The use of
futures transactions involves the risk of imperfect correlation in movements in
the price of futures contracts, interest rates and the underlying hedged assets.
Options: The Fund may either purchase or write options in order to hedge against
adverse market movements or fluctuations in value caused by changes in
prevailing interest rates with respect to securities which the Fund currently
owns or intends to purchase. When the Fund purchases an option, it pays a
premium and an amount equal to that premium is recorded as an investment. When
the Fund writes an option, it receives a premium and an amount equal to that
premium is recorded as a liability. The investment or liability is adjusted
daily to reflect the current market value of the option. If an option expires
unexercised, the Fund realizes a gain or loss to the extent of the premium
received or paid. If an option is exercised, the premium received or paid is an
adjustment to the proceeds from the sale or the cost basis of the purchase in
determining whether the Fund has realized a gain or loss. The difference between
the premium and the amount received or paid on effecting a closing purchase or
sale transaction is also treated as a realized gain or loss. Gain or loss on
purchased options is included in net realized gain (loss) on investment
transactions.
The Fund, as writer of an option, has no control over whether the underlying
securities may be sold (called) or purchased (put). As a result, the Fund bears
the market risk of an unfavorable change in the price of the security underlying
the written option. The Fund, as purchaser of an option, bears the risk of the
potential inability of the counterparties to meet the terms of their contracts.
Securities Transactions and Net Investment Income: Securities transactions are
recorded on the trade date. Realized gains and losses on sales of securities are
calculated on the identified cost basis. Interest income is recorded on the
accrual basis. The Fund amortizes premiums and accretes original issue discount
on portfolio securities as adjustments to interest income. Net investment
income, other than distribution fees, and realized and unrealized gains or
losses are allocated daily to each class of shares based upon the relative
proportion of net assets of each class at the

- --------------------------------------------------------------------------------
beginning of the day. Expenses are recorded on the accrual basis which may
require the use of certain estimates by management.
Federal Income Taxes: For federal income tax purposes, each series in the Fund
is treated as a separate tax paying entity. It is the intent of each series to
continue to meet the requirements of the Internal Revenue Code applicable to
regulated investment companies and to distribute all net income to shareholders.
For this reason no federal income tax provision is required.
Dividends and Distributions: Dividends from net investment income are declared
daily and paid monthly. The Fund will distribute at least annually any net
capital gains. Dividends and distributions are recorded on the ex-dividend date.
Income distributions and capital gain distributions are determined in accordance
with income tax regulations which may differ from generally accepted accounting
principles.
Reclassification of Capital Accounts: The Fund accounts and reports for
distributions to shareholders in accordance with Statement of Position 93-2:
Determination, Disclosure and Financial Statement Presentation of Income,
Capital Gain, and Return of Capital Distributions by Investment Companies. For
the fiscal year ended April 30, 1999, the effect of applying this statement was
to increase undistributed net investment income and increase accumulated net
realized losses by $297,786 due to the sale of securities purchased with market
discount for the Insured Series.
Custody Fee Credits: The Fund has an arrangement with its custodian bank,
whereby uninvested monies earn credits which reduce the fees charged by the
custodian.
- ------------------------------------------------------------
Note 2. Agreements
The Fund has a management agreement with Prudential Investments Fund Management
LLC ('PIFM'). Pursuant to this agreement, PIFM has responsibility for all
investment advisory services and supervises the subadviser's performance of such
services. PIFM has entered into a subadvisory agreement with The Prudential
Investment Corporation ('PIC'), doing business as Prudential Investments ('PI,'
the Subadviser or the investment adviser); PIC furnishes investment advisory
services in connection with the management of the Fund. PIFM pays for the cost
of the subadviser's services, the compensation of officers of the Fund,
occupancy and certain clerical and bookkeeping costs of the Fund. The Fund bears
all other costs and expenses.
The management fee paid PIFM is computed daily and payable monthly at an annual
rate of .50 of 1% of the average daily net assets of each series up to $1
billion and .45 of 1% of the average daily net assets of each series in excess
of $1 billion. PIFM has agreed to voluntarily waive a portion of the High Income
Series management fee, which amounted to $590,774. Such amount represents .05 of
1% of average daily net assets, or $.005 cents per share for the year ended
April 30, 1999. The Series is not required to reimburse PIFM for such waiver.
The Fund had a distribution agreement with Prudential Securities Incorporated
('PSI'), which acted as the distributor of the Class A, Class B, Class C and
Class Z shares of the Fund through May 31, 1998. Prudential Investment
Management Services LLC ('PIMS') became the distributor of the Fund effective
June 1, 1998 and is serving the Fund under the same terms and conditions as
under the arrangement with PSI. The Fund compensated PSI and PIMS for
distributing and servicing the Fund's Class A, Class B and Class C shares,
pursuant to plans of distribution (the 'Class A, B and C Plans'), regardless of
expenses actually incurred by them. The distribution fees are accrued daily and
payable monthly. No distribution or service fees were paid to PSI or PIMS as
distributor of the Class Z shares of the Fund.
Pursuant to the Class A, B and C Plans, the Fund compensated PSI and PIMS for
distribution-related activities at an annual rate of up to .30 of 1%, .50 of 1%
and 1%, of the average daily net assets of the Class A, B and C shares,
respectively, for the year ended April 30, 1999. Effective January 1, 1999, such
expenses for the Fund were .25 of 1%, .50 of 1% and .75 of 1% of the average
daily net assets of the Class A, B and C shares, respectively. Prior to January
1, 1999, such expenses under the Plans were .10 of 1%, .50 of 1% and .75 of 1%
of the average daily net assets of the Class A, B and C shares, respectively.
PSI and PIMS have advised the High Income Series and Insured Series that they
received approximately $679,000 ($600,700-Class A; $78,300-Class C) and $62,100
($54,100-Class A; $8,000-Class C), respectively, in front-end sales charges
during the year ended April 30, 1999. From these fees, PSI and PIMS paid such
sales charges to affiliated broker-dealers which in turn paid commissions to
salespersons and incurred other distribution costs.
PSI and PIMS have advised the Fund that for the year ended April 30, 1999, they
received approximately $776,500 ($765,300-Class B; $11,200-Class C) and $179,800
($179,700-Class B; $100-Class C), respectively, in contingent deferred sales
charges imposed upon certain redemptions by Class B and C shareholders.
PSI, PIC, PIMS and PIFM are indirect, wholly owned subsidiaries of The
Prudential Insurance Company of America.

As of March 11, 1999, the Fund, along with other affiliated registered
investment companies (the 'Funds'), entered into a syndicated credit agreement
('SCA') with an unaffiliated lender. The maximum commitment under the SCA is $1
billion. The Funds pay a commitment fee at an annual rate of .065 of 1% on the
unused portion of the credit facility, which is accrued and paid quarterly on a

Report of Independent Accountants              PRUDENTIAL MUNICIPAL BOND FUND
- --------------------------------------------------------------------------------
To the Shareholders and Trustees of
Prudential Municipal Bond Fund

In our opinion, the accompanying statements of assets and liabilities, including
the portfolios of investments, 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 High Income Series and Insured
Series (constituting Prudential Municipal Bond Fund, hereafter referred to as
the 'Fund') at April 30, 1999, the results of each of their operations for the
year then ended, the changes in each of their net assets for each of the two
years in the period then ended and the financial highlights for each of the
three years in the period then ended, 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 at April 30, 1999 by correspondence with the
custodian and brokers, provide a reasonable basis for the opinion expressed
above. The accompanying financial highlights for each of the two years in the
period ended April 30, 1996 were audited by other independent accountants, whose
opinion dated June 13, 1996 was unqualified.

Tax Information (Unaudited)                      PRUDENTIAL MUNICIPAL BOND FUND
- --------------------------------------------------------------------------------
As required by the Internal Revenue Code, we wish to advise you as to the
federal tax status of dividends and distributions paid by the Fund during its
fiscal year ended April 30, 1999.
During its fiscal year ended April 30, 1999, the Fund paid aggregate dividends
from net investment income, all of which were federally tax-exempt interest
dividends, as follows:

                              Insured Series................      $ .53        $ .48        $ .46        $ .54
</TABLE>

In addition to the above, the Insured Series paid dividends and distributions
totalling $.101 per share, comprised of $.008 ordinary income and $.057
short-term capital gains which are taxable as ordinary income and $.036
long-term capital gains which are taxable as such to Class A, B, C and Z
shareholders.
Shortly after the close of the calendar year ending December 31, 1999, you will
be advised again as to the federal tax status of the dividends and distributions
received in calendar 1999. In addition, you will be advised at that time as to
the portion of your dividends which may be subject to the Alternative Minimum
Tax (AMT) as well as information with respect to state taxability.

Getting The Most From Your Prudential Mutual Fund
Some mutual fund shareholders won't ever read this--they don't read annual and
semi-annual reports. It's quite understandable. These annual and semi-annual
reports are prepared to comply with Federal regulations. They are often written
in language that is difficult to understand. So, when most people run into
those particularly daunting sections of these reports, they don't read them.

We think that's a mistake.
At Prudential Mutual Funds, we've made some changes to our report to make it
easier to understand and more pleasant to read, in hopes you'll find it
profitable to spend a few minutes familiarizing yourself with your investment.
Here's what you'll find in the report:

At A Glance
Since an investment's performance is often a shareholder's primary concern, we
present performance information in two different formats. You'll find it first
on the "At A Glance" page where we compare the Fund and the comparable average
calculated by Lipper Analytical Services, a nationally recognized mutual fund
rating agency. We report both the cumulative total returns and the average
annual total returns. The cumulative total return is the total amount of income
and appreciation the Fund has achieved in various time periods. The average
annual total return is an annualized representation of the Fund's performance--
it generally smoothes out returns and gives you an idea how much the Fund has
earned in an average year, for a given time period. Under the performance box,
you'll see legends that explain the performance information, whether fees and
sales charges have been included in returns, and the inception dates for the
Fund's share classes.

See the performance comparison charts at the back of the report for more
performance information. And keep in mind that past performance is not
indicative of future results.

Portfolio Manager's Report
The portfolio manager who invests your money for you reports on successful--
and not-so-successful--strategies in this section of your report. Look for
recent purchases and sales here, as well as information about the sectors the
portfolio manager favors and any changes that are on the drawing board.

Portfolio Of Investments
This is where the report begins to look technical, but it's really just a
listing of each security held at the end of the reporting period, along with
valuations and other information. Please note that sometimes we discuss a
security in the Portfolio Manager's Report that doesn't appear in this listing
because it was sold before the close of the reporting period.

                                  44

<PAGE>

Statement Of Assets And Liabilities
The balance sheet shows the assets (the value of the Fund's holdings),
liabilities (how much the Fund owes) and net assets (the Fund's equity, or
holdings after the Fund pays its debts) as of the end of the reporting period.
It also shows how we calculate the net asset value per share for each class of
shares. The net asset value is reduced by payment of your dividend, capital
gain, or other distribution, but remember that the money or new shares are
being paid or issued to you. The net asset value fluctuates daily along with
the value of every security in the portfolio.

Statement Of Operations
This is the income statement, which details income (mostly interest and
dividends earned) and expenses (including what you pay us to manage your
money). You'll also see capital gains here -- both realized and unrealized.

Statement Of Changes In Net Assets
This schedule shows how income and expenses translate into changes in net
assets. The Fund is required to pay out the bulk of its income to shareholders
every year, and this statement shows you how we do it --  through dividends and
distributions -- and how that affects the net assets. This statement also shows
how money from investors flowed into and out of the Fund.

Notes To Financial Statements
This is the kind of technical material that can intimidate readers, but it does
contain useful information. The Notes provide a brief history and explanation
of your Fund's objectives. In addition, they also outline how Prudential
Mutual Funds prices securities. The Notes also explain who manages and
distributes the Fund's shares and, more importantly, how much they are paid for
doing so. Finally, the Notes explain how many shares are outstanding, and the
number issued and redeemed over the period.

Financial Highlights
This information contains many elements from prior pages, but on a per share
basis. It is designed to help you understand how the Fund performed, and to
compare this year's performance and expenses to those of prior years.

Independent Auditor's Report
Once a year, an outside auditor looks over our books and certifies that the
information is fairly presented and complies with generally accepted accounting
principles.

Tax Information
This is information which we report annually about how much of your total
return is taxable. Should you have any questions, you may want to consult a tax
advisor.

Performance Comparison
These charts are included in the annual report and are required by the
Securities Exchange Commission. Performance is presented here as a hypothetical
$10,000 investment in the Fund since its inception or for 10 years (whichever
is shorter). To help you put that return in context, we are required to include
the performance of an unmanaged, broad-based securities index, as well. The
index does not reflect the cost of buying the securities it contains or the
cost of managing a mutual fund. Of course, the index holdings do not mirror
those of the fund -- the index is a broadly based reference point commonly
used by investors to measure how well they are doing. A definition of the
selected index is also provided. Investors generally cannot invest directly in
an index.

Past performance is not indicative of future results. Principal and investment
returns will fluctuate so that an investor's shares, when redeemed, may be
worth more or less than their original cost. The lines beneath the graphs are
designed to give you an idea of how much the Series' returns can fluctuate from
year to year by measuring the best and worst calendar years in terms of total
annual return since the inception of each share class.

These graphs compare a $10,000 investment in the Prudential Municipal Bond
Fund--High Income Series (Class A, B, C, and Z shares) with a similar
investment in the Lehman Brothers Municipal Bond Index (the Index) by
portraying the account values at the commencement of operations of Class A, C,
and Z shares, at the beginning of the ten-year period for Class B shares; and
at the end of the fiscal year (April 30), as measured on a quarterly basis,
beginning in 1990 for Class A, 1989 for Class B, 1994 for Class C, and 1996 for
Class Z shares. For purposes of the graphs, and unless otherwise indicated, it
has been assumed that (a) the maximum applicable front-end sales charge was
deducted from the initial $10,000 investment in Class A and Class C shares;
(b) the maximum applicable contingent deferred sales charges were deducted from
the value of the investment in Class B and Class C shares, assuming full
redemption on April 30, 1999; (c) all recurring fees (including management
fees) were deducted; and (d) all dividends and distributions were reinvested.

seven years after purchase. This conversion feature is not reflected in the
graphs. The numbers in ( ) show the Series' average annual total return without
waiver of management fees and/or expense subsidization. Class Z shares are not
subject to a sales charge or distribution fee.

The Index is a weighted index comprised of municipal bonds (general obligation
bonds, revenue bonds, insured bonds, and prerefunded bonds) selected by Lehman
Brothers as representative of the long-term, investment-grade municipal bond
market. The Index is unmanaged, and the total return includes the reinvestment
of all dividends, but does not reflect the payment of transaction costs and
advisory fees associated with an investment in the Series. The securities in
the Index may differ substantially from the securities in the Fund. The Index
is not the only index that may be used to characterize performance of municipal
bond funds. Other indexes may portray different comparative performance.
Investors cannot invest directly in an index.
