PRUDENTIAL STRUCTURED MATURITY FUND, INC.
 
- -------------------------------------------------------------------------------
 
PROSPECTUS DATED AUGUST 1, 1994
 
- -------------------------------------------------------------------------------
 
Prudential Structured Maturity Fund, Inc. (the Fund), Income Portfolio (the
Portfolio), is one of two separate portfolios of an open-end, management
investment company, or mutual fund. The Portfolio's investment objective is
high current income consistent with the preservation of principal. The
Portfolio seeks to achieve its objective primarily through structuring its
portfolio by utilizing a "laddered" maturity strategy. The Portfolio invests
primarily in investment grade corporate debt securities and in obligations of
the U.S. Government, its agencies and instrumentalities with maturities of six
years or less. These securities are allocated by maturity among six annual
maturity categories ranging from one year or less to between five and six
years with each category representing approximately one-sixth of the
Portfolio's assets. As the securities in each annual category mature or as new
investments are made in the Portfolio, the proceeds will be invested to
maintain the balance of investments among the six annual maturity categories.
There can be no assurance that the Portfolio's investment objective will be
achieved. See "How the Fund Invests--Investment Objective and Policies." The
Fund's address is One Seaport Plaza, New York, New York 10292, and its
telephone number is (800) 225-1852.
 
This Prospectus sets forth concisely the information about the Fund and the
Income Portfolio that a prospective investor should know before investing.
Additional information about the Fund and the Portfolio has been filed with
the Securities and Exchange Commission in a Statement of Additional
Information, dated August 1, 1994, which information is incorporated herein by
reference (is legally considered a part of this Prospectus) and is available
without charge upon request to the Fund, at the address or telephone number
noted above.

                                FUND HIGHLIGHTS
 
 
   The following summary is intended to highlight certain information
 contained in the Prospectus and is qualified in its entirety by the more
 detailed information appearing elsewhere herein.
WHAT IS PRUDENTIAL STRUCTURED MATURITY FUND, INC.?
 
  Prudential Structured Maturity Fund, Inc. is a mutual fund whose shares are
offered in two portfolios, each of which operates as a separate fund. A mutual
fund pools the resources of investors by selling its shares to the public and
investing the proceeds of such sale in a portfolio of securities designed to
achieve its investment objective. Technically, the Fund is an open-end
management investment company. Only the Income Portfolio is offered through
this Prospectus.
 
WHAT IS THE PORTFOLIO'S INVESTMENT OBJECTIVE?
 
  The Portfolio's investment objective is high current income consistent with
the preservation of principal. It seeks to achieve this objective primarily
through structuring its portfolio by utilizing a "laddered" maturity strategy.
The Portfolio invests primarily in investment grade corporate debt securities
and in obligations of the U.S. Government, its agencies and instrumentalities
with maturities of six years or less. These securities are allocated by
maturity among six annual maturity categories ranging from one year or less to
between five and six years with each category representing approximately one-
sixth of the Fund's assets ("laddered" maturities). There can be no assurance
that the Portfolio's objective will be achieved. See "How the Fund Invests--
Investment Objective and Policies" at page 6.
 
RISK FACTORS AND SPECIAL CHARACTERISTICS
 
  The Portfolio may invest in debt securities of U.S. issuers that have
securities outstanding that are rated at the time of purchase at least BBB by
Standard & Poor's Ratings Group (S&P) or Baa by Moody's Investors Service
(Moody's) or a similar nationally recognized rating service or, if not rated,
of comparable quality in the opinion of the investment adviser. In addition,
the Portfolio may invest up to 10% of its total assets in securities rated
below BBB by S&P or Baa by Moody's or a similar nationally recognized rating
service or, if not rated, of comparable quality in the opinion of the
investment adviser. Such securities are commonly referred to as "junk bonds."
The Portfolio may invest up to 25% of its net assets in asset-backed securities
and up to 30% of its assets in collateralized mortgage obligations and real
estate mortgage investment conduits. Such investments may be sensitive to
prepayments and interest rates. See "How the Fund Invests--Investment Objective
and Policies--Corporate and Other Debt Obligations" at page 8. The Portfolio
may also engage in various hedging and income enhancement strategies, including
derivatives. See "How the Fund Invests--Hedging and Income Enhancement
Strategies--Risks of Hedging and Income Enhancement Strategies" at page 11.
 
WHO MANAGES THE FUND?
 
  Prudential Mutual Fund Management, Inc. (PMF or the Manager) is the Manager
of the Fund and is compensated for its services at an annual rate of .40 of 1%
of the Portfolio's average daily net assets. As of June 30, 1994, PMF served as
manager or administrator to 66 investment companies, including 37 mutual funds,
with aggregate assets of approximately $47 billion. The Prudential Investment
Corporation (PIC or the Subadviser) furnishes investment advisory services in
connection with the management of the Fund under a Subadvisory Agreement with
PMF. See "How the Fund is Managed--Manager" at page 14.
 
WHO DISTRIBUTES THE PORTFOLIO'S SHARES?
 
  Prudential Mutual Fund Distributors, Inc. (PMFD) acts as the Distributor of
the Portfolio's Class A shares and is paid an annual distribution and service
fee which is currently being charged at the rate of .10 of 1% of the average
daily net assets of the Class A shares.
 
                                       2
<PAGE>
 
 
  Prudential Securities Incorporated (Prudential Securities or PSI), a major
securities underwriter and securities and commodities broker, acts as the
Distributor of the Portfolio's Class B and Class C shares and is paid an annual
distribution and service fee which is currently being charged at the rate of
.75 of 1% of the average daily net assets of each of the Class B and Class C
shares.
 
  See "How the Fund is Managed--Distributor" at page 15.
 
WHAT IS THE MINIMUM INVESTMENT?
 
  The minimum initial investment for Class A and Class B shares is $1,000 per
class and $5,000 for Class C shares. The minimum subsequent investment is $100
for all classes. There is no minimum investment requirement for certain
retirement and employee savings plans or custodial accounts for the benefit of
minors. For purchases made through the Automatic Savings Accumulation Plan, the
minimum initial and subsequent investment is $50. See "Shareholder Guide--How
to Buy Shares of the Fund" at page 20 and "Shareholder Guide--Shareholder
Services" at page 28.
 
HOW DO I PURCHASE SHARES?
 
  You may purchase shares of the Portfolio through Prudential Securities, Pruco
Securities Corporation (Prusec) or directly from the Fund, through its transfer
agent, Prudential Mutual Fund Services, Inc. (PMFS or the Transfer Agent) at
the net asset value per share (NAV) next determined after receipt of your
purchase order by the Transfer Agent or Prudential Securities plus a sales
charge which may be imposed either (i) at the time of purchase (Class A shares)
or (ii) on a deferred basis (Class B or Class C shares). See "How the Fund
Values its Shares" at page 17 and "Shareholder Guide--How to Buy Shares of the
Fund" at page 20.
 
WHAT ARE MY PURCHASE ALTERNATIVES?
 
  The Portfolio offers three classes of shares:
 
  .Class A Shares:   Sold with an initial sales charge of up to 3.25% of the
   offering price.
  .Class B Shares:   Sold without an initial sales charge but are subject to
                 a contingent deferred sales charge or CDSC (declining from
                 3% to zero of the lower of the amount invested or the
                 redemption proceeds) which will be imposed on certain
                 redemptions made within four years of purchase. Although
                 Class B shares are subject to higher ongoing distribution-
                 related expenses than Class A shares, Class B shares will
                 automatically convert to Class A shares (which are subject
                 to lower ongoing distribution-related expenses)
                 approximately five years after purchase.
  .Class C Shares:   Sold without an initial sales charge and, for one year
                     after purchase, are subject to a 1% CDSC on redemptions.
                     Like Class B shares, Class C shares are subject to
                     higher ongoing distribution-related expenses than Class
                     A shares but do not convert to another class.
 
  See "Shareholder Guide--Alternative Purchase Plan" at page 21.
 
HOW DO I SELL MY SHARES?
 
  You may redeem shares of the Portfolio at any time at the NAV next determined
after Prudential Securities or the Transfer Agent receives your sell order.
However, the proceeds of redemptions of Class B and Class C shares may be
subject to a CDSC. See "Shareholder Guide--How to Sell Your Shares" at page 23.
 
HOW ARE DIVIDENDS AND DISTRIBUTIONS PAID?
 
  The Portfolio expects to declare daily and pay monthly dividends of net
investment income, if any, and make distributions of any net capital gains at
least annually. Dividends and distributions will be automatically reinvested in
additional shares of the Fund at NAV without a sales charge unless you request
that they be paid to you in cash. See "Taxes, Dividends and Distributions" at
page 18.

You would pay the following expenses on a
$1,000 investment, assuming (1) 5% annual re-
turn and (2) redemption at the end of each time
period:
 Class A.......................................   $40     $57     $75     $128
 Class B.......................................   $46     $59     $84     $132

The above example with respect to Class A shares is based on data for the
Fund's fiscal year ended December 31, 1993. The above example with respect to
Class B shares is based on restated data for the fiscal year ended December 31,
1993. The above example with respect to Class C shares is based on expenses
expected to have been incurred if Class C shares had been in existence during
the fiscal year ended December 31, 1993. The example should not be considered a
representation of past or future expenses. Actual expenses may be greater or
less than those shown.
 
The purpose of this table is to assist investors in understanding the various
costs and expenses that an investor in the Portfolio will bear, whether
directly or indirectly. For more complete descriptions of the various costs and
expenses, see "How the Fund is Managed." "Other Expenses" includes an estimate
of operating expenses of the Portfolio, such as directors' and professional
fees, registration fees, reports to shareholders and transfer agency and
custodian fees.
- ------------
  * Class B Shares will automatically convert to Class A shares approximately
    five years after purchase. See "Shareholder Guide--Conversion Feature--
    Class B Shares."
 ** Estimated based on expenses expected to have been incurred if Class C
    shares had been in existence during the fiscal year ended December 31,
    1993.
*** Although the Class A Distribution and Service Plan provides that the
    Portfolio may pay a distribution fee of up to .30 of 1% per annum of the
    average daily net assets of the Class A shares, the Distributor has agreed
    to limit its distribution fees with respect to the Class A shares of the
    Portfolio to no more than .10 of 1% for the fiscal year ending December 31,
    1994. Total operating expenses without such limitation would be 1.00%.
  + Pursuant to the rules of the National Association of Securities Dealers,
    Inc., the aggregate initial sales charges, deferred sales charges and
    asset-based sales charges on shares of the Portfolio may not exceed 6.25%
    of total gross sales, subject to certain exclusions. This 6.25% limitation
    is imposed on each class of the Portfolio rather than on a per shareholder
    basis. Therefore, long-term shareholders of the Portfolio may pay more in
    total sales charges than the economic equivalent of 6.25% of such
    shareholders' investments in such shares. See "How the Fund is Managed--
    Distributor."
 ++ Although the Class B and Class C Distribution and Service Plans provide
    that the Portfolio may pay a distribution fee of up to 1% per annum of the
    average daily net assets of the Class B and Class C shares, the Distributor
    has agreed to limit its distribution fees with respect to Class B and Class
    C shares of the Portfolio to no more than .75 of 1% of the average daily
    net assets of each of the Class B and Class C shares for the fiscal year
    ending December 31, 1994. Total operating expenses of the Class B and Class
    C Shares without such limitations would be 1.70% and 1.70%, respectively.

  distributions. Total returns for periods of less than one year are not
  annualized.

                             HOW THE FUND INVESTS
 
 
INVESTMENT OBJECTIVE AND POLICIES
 
  PRUDENTIAL STRUCTURED MATURITY FUND, INC. IS AN OPEN-END MANAGEMENT
INVESTMENT COMPANY, OR MUTUAL FUND, CONSISTING OF TWO PORTFOLIOS. EACH
PORTFOLIO IS MANAGED INDEPENDENTLY. THE INCOME PORTFOLIO'S INVESTMENT
OBJECTIVE IS HIGH CURRENT INCOME CONSISTENT WITH THE PRESERVATION OF
PRINCIPAL. THE PORTFOLIO SEEKS TO ACHIEVE THIS OBJECTIVE PRIMARILY THROUGH
STRUCTURING ITS PORTFOLIO BY UTILIZING A "LADDERED" MATURITY STRATEGY. THE
PORTFOLIO INVESTS PRIMARILY IN INVESTMENT GRADE CORPORATE DEBT SECURITIES AND
IN OBLIGATIONS OF THE U.S. GOVERNMENT, ITS AGENCIES AND INSTRUMENTALITIES WITH
MATURITIES OF SIX YEARS OR LESS. THESE SECURITIES ARE ALLOCATED BY MATURITY
AMONG SIX ANNUAL MATURITY CATEGORIES RANGING FROM ONE YEAR OR LESS TO BETWEEN
FIVE AND SIX YEARS WITH EACH CATEGORY REPRESENTING APPROXIMATELY ONE-SIXTH OF
THE PORTFOLIO'S ASSETS ("LADDERED" MATURITIES). AS THE SECURITIES IN EACH
ANNUAL CATEGORY MATURE OR AS NEW INVESTMENTS ARE MADE IN THE PORTFOLIO, THE
PROCEEDS WILL BE INVESTED TO MAINTAIN THE BALANCE OF INVESTMENTS AMONG THE SIX
ANNUAL MATURITY CATEGORIES. THERE CAN BE NO ASSURANCE THAT SUCH OBJECTIVE WILL
BE ACHIEVED. See "Investment Objective and Policies" in the Statement of
Additional Information.
 
  THE PORTFOLIO'S INVESTMENT OBJECTIVE IS A FUNDAMENTAL POLICY AND, THEREFORE,
MAY NOT BE CHANGED WITHOUT THE APPROVAL OF THE HOLDERS OF A MAJORITY OF THE
PORTFOLIO'S OUTSTANDING VOTING SECURITIES, AS DEFINED IN THE INVESTMENT
COMPANY ACT OF 1940, AS AMENDED (THE INVESTMENT COMPANY ACT). POLICIES OF THE
PORTFOLIO THAT ARE NOT FUNDAMENTAL MAY BE MODIFIED BY THE BOARD OF DIRECTORS.
 
  THE PORTFOLIO SEEKS TO PROVIDE INVESTORS WITH MORE STABILITY OF PRINCIPAL
THAN LONG-TERM BONDS HAVE HISTORICALLY PROVIDED THROUGH THE STRUCTURED
PORTFOLIO MANAGEMENT STRATEGY OF INVESTING IN SHORT- TO INTERMEDIATE-TERM DEBT
SECURITIES. LADDERING INVESTMENTS AMONG DEBT INSTRUMENTS WITH A RANGE OF
MATURITIES OF FROM ONE YEAR OR LESS TO SIX YEARS PROVIDES AN ADDED DEGREE OF
PORTFOLIO VARIATION, WHICH TENDS TO REDUCE VOLATILITY TO A LEVEL LOWER THAN
THAT EXPERIENCED BY A LONG-TERM BOND FUND. In general, the longer the maturity
of a debt security, the higher the yield and the greater the potential for
price fluctuation. Conversely, shorter maturities generally provide lower
yields but greater principal stability. The prices of fixed-income securities
are likely to vary inversely with interest rates. The Portfolio has the
potential for high current yields although they may not be as high as those of
a long-term bond fund. The investment adviser has had experience structuring
portfolios with laddered maturities for institutional clients since 1977.
 
  Under normal market circumstances, the Portfolio will invest its assets in
U.S. Government securities and investment grade corporate debt obligations
having "laddered" maturities ranging from one year or less to six years. The
Portfolio's investment adviser will allocate assets among the various
categories by maturity and not by type of investment and will continuously
monitor each annual category. The investment adviser will buy and sell
portfolio securities to take advantage of investment opportunities based on
its analysis of market conditions, interest rates and general economic
factors, thereby increasing the Portfolio's annual portfolio turnover rate.
From time to time, the Portfolio may also sell portfolio securities to meet
redemption requests.
 
  During times of portfolio structuring as well as when the investment adviser
deems it necessary for defensive purposes or to provide liquidity, assets of
the Portfolio may be invested temporarily in high quality money market
instruments and repurchase agreements.
 
  The Portfolio's effective dollar-weighted average maturity is expected to be
between 2 1/2 and 3 1/2 years. See "U.S. Government Securities--Mortgage-
Related Securities Issued by U.S. Government Agencies and Instrumentalities"
below.
 
U.S. GOVERNMENT SECURITIES
 
  U.S. TREASURY SECURITIES. THE PORTFOLIO WILL INVEST IN U.S. TREASURY
SECURITIES, INCLUDING BILLS, NOTES AND BONDS. These instruments are direct
obligations of the U.S. Government and, as such, are backed by the "full faith
and credit" of the United States. They differ primarily in their interest
rates and the lengths of their maturities.
 
                                       6
<PAGE>
 
  SECURITIES ISSUED OR GUARANTEED BY U.S. GOVERNMENT AGENCIES AND
INSTRUMENTALITIES. THE PORTFOLIO WILL INVEST IN OBLIGATIONS ISSUED OR
GUARANTEED BY AGENCIES OF THE U.S. GOVERNMENT OR INSTRUMENTALITIES ESTABLISHED
OR SPONSORED BY THE U.S. GOVERNMENT. THESE OBLIGATIONS, INCLUDING THOSE WHICH
ARE GUARANTEED BY FEDERAL AGENCIES OR INSTRUMENTALITIES, MAY OR MAY NOT BE
BACKED BY THE "FULL FAITH AND CREDIT" OF THE UNITED STATES. Obligations of the
Government National Mortgage Association (GNMA), the Farmers Home
Administration and the Export-Import Bank are backed by the "full faith and
credit" of the United States. In the case of securities not backed by the full
faith and credit of the United States, the Portfolio must look principally to
the agency issuing or guaranteeing the obligation for ultimate repayment and
may not be able to assert a claim against the United States if the agency or
instrumentality does not meet its commitments. Securities of this type in
which the Portfolio may invest that are not backed by the full faith and
credit of the United States include obligations which generally may be
satisfied only by the individual credit of the issuing agency, such as
obligations of the Federal National Mortgage Association (FNMA), the Federal
Home Loan Mortgage Corporation (FHLMC) and the Resolution Funding Corporation.
GNMA, FNMA and FHLMC investments may include collateralized mortgage
obligations. See "Corporate and Other Debt Obligations" below.
 
  Obligations issued or guaranteed as to principal and interest by the U.S.
Government may be acquired by the Portfolio in the form of custodial receipts
that evidence ownership of future interest payments, principal payments or
both on certain United States Treasury notes or bonds. Such notes and bonds
are held in custody by a bank on behalf of the owners. These custodial
receipts are commonly referred to as Treasury strips. See "Investment
Objective and Policies--U.S. Government Securities" in the Statement of
Additional Information.
 
  MORTGAGE-RELATED SECURITIES ISSUED BY U.S. GOVERNMENT AGENCIES AND
INSTRUMENTALITIES. THE PORTFOLIO MAY INVEST IN MORTGAGE-BACKED SECURITIES THAT
ARE ISSUED BY FNMA OR FHLMC OR GUARANTEED BY GNMA AND WHICH REPRESENT
UNDIVIDED OWNERSHIP INTERESTS IN POOLS OF MORTGAGES. The U.S. Government or
the issuing agency or instrumentality guarantees the payment of interest on
and principal of these securities; however, the guarantees do not extend to
the yield or value of the securities nor do the guarantees extend to the yield
or value of the Portfolio's shares. These securities are in most cases "pass-
through" instruments, through which the holders receive a share of all
interest and principal payments from the mortgages underlying the securities,
net of certain fees. As a result of the pass-through of prepayments of
principal on the underlying securities, mortgage-backed securities are often
subject to more rapid prepayment of principal than their stated maturity would
indicate. The remaining expected average life of a pool of mortgage loans
underlying a mortgage-backed security is a prediction of when the mortgage
loans will be repaid and is based upon a variety of factors, such as the
demographic and geographic characteristics of the borrowers and the mortgaged
properties, the length of time that each of the mortgage loans has been
outstanding, the interest rates payable on the mortgage loans and the current
interest rate environment. The remaining maturity of a mortgage-backed
security will be deemed to be equal to the average maturity of the mortgages
underlying such security determined by the investment adviser on the basis of
assumed prepayment rates with respect to such mortgages. See "Investment
Objective and Policies" in the Statement of Additional Information.
 
  THE PORTFOLIO WILL INVEST IN BOTH ADJUSTABLE RATE MORTGAGE SECURITIES
(ARMS), WHICH ARE PASS-THROUGH MORTGAGE SECURITIES COLLATERALIZED BY
ADJUSTABLE RATE MORTGAGES, AND FIXED RATE MORTGAGE SECURITIES (FRMS), WHICH
ARE SECURITIES COLLATERALIZED BY FIXED RATE MORTGAGES. See "Investment
Objective and Policies--U.S. Government Securities" in the Statement of
Additional Information.
 
  THE PORTFOLIO MAY ALSO INVEST IN BALLOON PAYMENT MORTGAGE-BACKED SECURITIES.
A balloon payment mortgage-backed security is an amortizing mortgage security
with installments of principal and interest, the last installment of which is
predominantly principal.
 
  THE PORTFOLIO MAY ALSO INVEST IN MORTGAGE PASS-THROUGH SECURITIES WHERE ALL
INTEREST PAYMENTS GO TO ONE CLASS OF HOLDERS (INTEREST ONLY SECURITIES OR IOS)
AND ALL PRINCIPAL PAYMENTS GO TO A SECOND CLASS OF HOLDERS (PRINCIPAL
 
                                       7
<PAGE>
 
ONLY SECURITIES OR POS). THESE SECURITIES ARE COMMONLY REFERRED TO AS
MORTGAGE-BACKED SECURITIES STRIPS OR MBS STRIPS. The yields to maturity on IOs
are very sensitive to the rate of principal payments (including prepayments)
on the related underlying mortgage assets, and a rapid rate of principal
payments may have a material adverse effect on yield to maturity. If the
underlying mortgage assets experience greater than anticipated prepayments of
principal, the Portfolio may not fully recoup its initial investment in these
securities. Conversely, if the underlying mortgage assets experience less than
anticipated prepayments of principal, the yield on POs could be materially
adversely affected.
 
CORPORATE AND OTHER DEBT OBLIGATIONS
 
  THE PORTFOLIO MAY INVEST IN DEBT SECURITIES OF U.S. ISSUERS THAT HAVE
SECURITIES OUTSTANDING THAT ARE RATED AT THE TIME OF PURCHASE AT LEAST BBB BY
STANDARD & POOR'S RATINGS GROUP (S&P) OR BAA BY MOODY'S INVESTORS SERVICE
(MOODY'S) OR A SIMILAR NATIONALLY RECOGNIZED RATING SERVICE OR, IF NOT RATED,
OF COMPARABLE QUALITY IN THE OPINION OF THE INVESTMENT ADVISER. THE FUND MAY
ALSO INVEST UP TO 10% OF TOTAL ASSETS IN SECURITIES RATED BELOW BBB OR BAA BY
S&P OR MOODY'S, RESPECTIVELY (OR A SIMILAR NATIONALLY RECOGNIZED RATING
SERVICE), OR, IF NOT RATED, OF COMPARABLE QUALITY IN THE OPINION OF THE
INVESTMENT ADVISER. Securities rated Baa by Moody's are considered to be
investment grade, although they have speculative characteristics. Changes in
economic or other circumstances are more likely to lead to a weakened capacity
of issuers whose securities are rated BBB or Baa to pay interest or repay
principal than is the case for issuers of higher rated securities. Securities
rated below Baa by Moody's and below BBB by S&P are considered speculative.
See "Description of Security Ratings" in the Appendix to this Prospectus. Such
securities are commonly referred to as "junk bonds." Such securities generally
offer a higher yield than those in the higher rated categories but also
involve greater risk of loss of principal and income and may also be subject
to greater price volatility due to the market's perceptions of the
creditworthiness of the issuer.
 
  THE PORTFOLIO MAY INVEST IN WHOLE LOAN MORTGAGE-BACKED SECURITIES ISSUED
OTHER THAN BY U.S. GOVERNMENT AGENCIES AND RATED AT LEAST AA BY S&P OR AA BY
MOODY'S. See "Investment Objective and Policies--Mortgage-Backed Securities"
in the Statement of Additional Information.
 
  THE CORPORATE OBLIGATIONS IN WHICH THE PORTFOLIO MAY INVEST INCLUDE ASSET-
BACKED SECURITIES, COLLATERALIZED MORTGAGE OBLIGATIONS AND REAL ESTATE
MORTGAGE INVESTMENT CONDUITS. THE PORTFOLIO MAY INVEST UP TO 25% OF ITS NET
ASSETS IN ASSET-BACKED SECURITIES AND UP TO 30% IN COLLATERALIZED MORTGAGE
OBLIGATIONS AND REAL ESTATE MORTGAGE INVESTMENT CONDUITS.
 
RISKS OF INVESTING IN HIGH YIELD SECURITIES
 
  FIXED-INCOME SECURITIES ARE SUBJECT TO THE RISK OF AN ISSUER'S INABILITY TO
MEET PRINCIPAL AND INTEREST PAYMENTS ON THE OBLIGATIONS (CREDIT RISK) AND MAY
ALSO BE SUBJECT TO PRICE VOLATILITY DUE TO SUCH FACTORS AS INTEREST RATE
SENSITIVITY AND THE MARKET PERCEPTION OF THE CREDITWORTHINESS OF THE ISSUER
(MARKET RISK). Lower rated or unrated (i.e., high yield) securities are more
likely to react to developments affecting market and credit risk than are more
highly rated securities, which react primarily to movements in the general
level of interest rates. The investment adviser considers both credit risk and
market risk in making investment decisions for the Fund. See "Investment
Objective and Policies--Other Investments--Risk Factors Relating to Investing
in High Yield Securities" in the Statement of Additional Information.
 
  ASSET-BACKED SECURITIES. THROUGH THE USE OF TRUSTS AND SPECIAL PURPOSE
CORPORATIONS, VARIOUS TYPES OF ASSETS, PRIMARILY HOME EQUITY LOANS AND
AUTOMOBILE AND CREDIT CARD RECEIVABLES, ARE BEING SECURITIZED IN PASS-THROUGH
STRUCTURES SIMILAR TO THE MORTGAGE PASS-THROUGH STRUCTURES DESCRIBED ABOVE OR
IN A PAY-THROUGH STRUCTURE SIMILAR TO THE COLLATERALIZED MORTGAGE STRUCTURE.
THE PORTFOLIO MAY INVEST IN THESE AND OTHER TYPES OF ASSET-BACKED SECURITIES
WHICH MAY BE DEVELOPED IN THE FUTURE. Asset-backed securities present certain
risks that are not presented by mortgage-backed securities. Primarily, these
securities do not have the benefit of the same security interest in the
related collateral. Credit card receivables are generally unsecured and
debtors are entitled to the protection of a number of state and federal
 
                                       8
<PAGE>
 
consumer credit laws, some of which may reduce the ability to obtain full
payment. In the case of automobile receivables, the security interests in the
underlying automobiles are often not transferred when the pool is created,
with the resulting possibility that the collateral could be resold. The
remaining maturity of an asset-backed security will be deemed to be equal to
the average maturity of the assets underlying such security determined by the
investment adviser on the basis of assumed prepayment rates and other factors
with respect to such assets. In general, these types of loans are of shorter
duration than mortgage loans and are less likely to have substantial
prepayments.
 
  COLLATERALIZED MORTGAGE OBLIGATIONS (CMOS) AND REAL ESTATE MORTGAGE
INVESTMENT CONDUITS (REMICS). A CMO IS A DEBT SECURITY THAT IS BACKED BY A
PORTFOLIO OF MORTGAGES OR MORTGAGE-BACKED SECURITIES. THE ISSUER'S OBLIGATION
TO MAKE INTEREST AND PRINCIPAL PAYMENTS IS SECURED BY THE UNDERLYING PORTFOLIO
OF MORTGAGES OR MORTGAGE-BACKED SECURITIES. Typically, CMOs are collateralized
by GNMA, FNMA or FHLMC certificates, but also may be collateralized by whole
loans or private mortgage pass-through securities (such collateral
collectively hereinafter referred to as "Mortgage Assets"). Multi-class pass-
through securities are equity interests in a trust composed of Mortgage
Assets. Payments of principal and interest on the Mortgage Assets, and any
reinvestment income thereon, provide the funds to pay debt service on the CMOs
or make scheduled distributions on the multi-class pass-through securities.
CMOs may be issued by agencies or instrumentalities of the U.S. Government, or
by private originators of, or investors in, mortgage loans, including
depository institutions, mortgage banks, investment banks and special purpose
subsidiaries of the foregoing. The issuer of a series of CMOs may elect to be
treated as a REMIC. All future references to CMOs shall also be deemed to
include REMICs.
 
  In a CMO, a series of bonds or certificates is issued in multiple classes.
Each class of CMOs, often referred to as a "tranche," is issued at a specific
fixed or floating coupon rate and has a stated maturity or final distribution
date. Principal prepayments on the Mortgage Assets may cause the CMOs to be
retired substantially earlier than their stated maturities or final
distribution dates. Interest is paid or accrues on all classes of the CMOs on
a monthly, quarterly or semi-annual basis. The principal and interest on the
Mortgage Assets may be allocated among the several classes of a CMO series in
a number of different ways. Generally, the purpose of the allocation of the
cash flow of a CMO to the various classes is to obtain a more predictable cash
flow to the individual tranches than exists with the underlying collateral of
the CMO. As a general rule, the more predictable the cash flow is on a CMO
tranche, the lower the anticipated yield will be on that tranche at the time
of issuance relative to prevailing market yields on mortgage-backed
securities.
 
  In reliance on rules and interpretations of the Securities and Exchange
Commission (SEC), the Fund's investments in certain qualifying CMOs and REMICs
are not subject to the Investment Company Act's limitation on acquiring
interests in other investment companies. See "Investment Objective and
Policies--Mortgage-Backed Securities--Collateralized Mortgage Obligations" in
the Statement of Additional Information. CMOs and REMICs issued by an agency
or instrumentality of the U.S. Government are considered U.S. Government
securities for purposes of this Prospectus.
 
  RISK FACTORS RELATING TO INVESTING IN MORTGAGE-BACKED AND ASSET-BACKED
SECURITIES. THE YIELD CHARACTERISTICS OF MORTGAGE-BACKED AND ASSET-BACKED
SECURITIES DIFFER FROM TRADITIONAL DEBT SECURITIES. AMONG THE MAJOR
DIFFERENCES ARE THAT INTEREST AND PRINCIPAL PAYMENTS ARE MADE MORE FREQUENTLY,
USUALLY MONTHLY, AND PRINCIPAL MAY BE PREPAID AT ANY TIME BECAUSE THE
UNDERLYING MORTGAGE LOANS OR OTHER ASSETS GENERALLY MAY BE PREPAID AT ANY
TIME. AS A RESULT, IF THE PORTFOLIO PURCHASES SUCH A SECURITY AT A PREMIUM, A
PREPAYMENT RATE THAT IS FASTER THAN EXPECTED WILL REDUCE YIELD TO MATURITY,
WHILE A PREPAYMENT RATE THAT IS SLOWER THAN EXPECTED WILL HAVE THE OPPOSITE
EFFECT OF INCREASING YIELD TO MATURITY. ALTERNATIVELY, IF THE PORTFOLIO
PURCHASES THESE SECURITIES AT A DISCOUNT, FASTER THAN EXPECTED PREPAYMENTS
WILL INCREASE, WHILE SLOWER THAN EXPECTED PREPAYMENTS WILL REDUCE, YIELD TO
MATURITY. THE PORTFOLIO MAY INVEST A PORTION OF ITS ASSETS IN DERIVATIVE
MORTGAGE-BACKED SECURITIES SUCH AS MBS STRIPS WHICH ARE HIGHLY SENSITIVE TO
CHANGES IN PREPAYMENT AND INTEREST RATES. THE INVESTMENT ADVISER WILL SEEK TO
MANAGE THESE RISKS (AND POTENTIAL BENEFITS) BY DIVERSIFYING ITS INVESTMENTS IN
SUCH SECURITIES AND THROUGH HEDGING TECHNIQUES.
 
  IN ADDITION, MORTGAGE-BACKED SECURITIES WHICH ARE SECURED BY MANUFACTURED
(MOBILE) HOMES AND MULTI-FAMILY RESIDENTIAL PROPERTIES, SUCH AS GNMA AND FNMA
CERTIFICATES, ARE SUBJECT TO A HIGHER RISK OF DEFAULT THAN ARE OTHER
 
                                       9
<PAGE>
 
TYPES OF MORTGAGE-BACKED SECURITIES. See "Investment Objective and Policies"
in the Statement of Additional Information. The investment adviser will seek
to minimize this risk by investing in mortgage-backed securities rated at
least A by Moody's and S&P. See "Asset-Backed Securities" above.
 
  Although the extent of prepayments on a pool of mortgage loans depends on
various economic and other factors, as a general rule prepayments on fixed
rate mortgage loans will increase during a period of falling interest rates
and decrease during a period of rising interest rates. Accordingly, amounts
available for reinvestment by the Portfolio are likely to be greater during a
period of declining interest rates and, as a result, likely to be reinvested
at lower interest rates than during a period of rising interest rates. Asset-
backed securities, although less likely to experience the same prepayment rate
as mortgage-backed securities, may respond to certain of the same factors
influencing prepayments, while at other times different factors may
predominate. Mortgage-backed securities and asset-backed securities may
decrease in value as a result of increases in interest rates and may benefit
less than other fixed-income securities from declining interest rates because
of the risk of prepayment.
 
  ASSET-BACKED SECURITIES INVOLVE CERTAIN RISKS THAT ARE NOT POSED BY
MORTGAGE-BACKED SECURITIES, RESULTING MAINLY FROM THE FACT THAT ASSET-BACKED
SECURITIES DO NOT USUALLY CONTAIN THE COMPLETE BENEFIT OF A SECURITY INTEREST
IN THE RELATED COLLATERAL. For example, credit card receivables generally are
unsecured and the debtors are entitled to the protection of a number of state
and federal consumer credit laws, some of which may reduce the ability to
obtain full payment. In the case of automobile receivables, due to various
legal and economic factors, proceeds from repossessed collateral may not
always be sufficient to support payments on these securities.
 
  STRIPPED MORTGAGE-BACK SECURITIES. In addition to MBS strips issued by
agencies or instrumentalities of the U.S. Government, the Portfolio may
purchase MBS strips issued by private originators of, or investors in,
mortgage loans, including depository institutions, mortgage banks, investment
banks and special purpose subsidiaries of the foregoing.
 
  YANKEE OBLIGATIONS. THE PORTFOLIO MAY INVEST IN U.S. DOLLAR-DENOMINATED DEBT
SECURITIES OF FOREIGN CORPORATIONS ISSUED IN THE UNITED STATES AND U.S.
DOLLAR-DENOMINATED DEBT SECURITIES ISSUED OR GUARANTEED AS TO PAYMENT OF
PRINCIPAL AND INTEREST BY GOVERNMENTS, QUASI-GOVERNMENTAL ENTITIES, GOVERNMENT
AGENCIES, SUPRANATIONAL ENTITIES AND OTHER GOVERNMENTAL ENTITIES OF FOREIGN
COUNTRIES, WHICH SECURITIES ARE ISSUED IN THE UNITED STATES (YANKEE
OBLIGATIONS). A supranational entity is an entity constituted by the national
governments of several countries to promote economic development, such as the
World Bank (International Bank for Reconstruction and Development), the
European Investment Bank and the Asian Development Bank. Debt securities of
quasi-governmental entities are issued by entities owned by either a national,
state or equivalent government or are obligations of a political unit that is
not backed by the national government's full faith and credit and general
taxing powers. These include, among others, the Province of Ontario and the
City of Tokyo.
 
  INVESTMENTS IN OBLIGATIONS OF FOREIGN ISSUERS MAY BE SUBJECT TO CERTAIN
RISKS, INCLUDING FUTURE POLITICAL AND ECONOMIC DEVELOPMENTS, THE POSSIBLE
IMPOSITION OF WITHHOLDING TAXES ON INTEREST INCOME, THE SEIZURE OR
NATIONALIZATION OF FOREIGN DEPOSITS AND FOREIGN EXCHANGE CONTROLS OR OTHER
RESTRICTIONS. IN ADDITION, THERE MAY BE LESS PUBLICLY AVAILABLE INFORMATION
ABOUT A FOREIGN ISSUER THAN ABOUT A DOMESTIC ISSUER AND SUCH ENTITIES MAY NOT
BE SUBJECT TO THE SAME ACCOUNTING, AUDITING AND FINANCIAL RECORDKEEPING
STANDARDS AND REQUIREMENTS AS DOMESTIC ISSUERS.
 
HEDGING AND INCOME ENHANCEMENT STRATEGIES
 
  THE PORTFOLIO MAY ALSO ENGAGE IN VARIOUS PORTFOLIO STRATEGIES, INCLUDING
DERIVATIVES, TO REDUCE CERTAIN RISKS OF ITS INVESTMENTS AND TO ATTEMPT TO
ENHANCE INCOME, BUT NOT FOR SPECULATION. These strategies include the use of
interest rate swap transactions and Eurodollar futures contracts and options
thereon. The Portfolio's ability to use these strategies may be limited by
market conditions, regulatory limits and tax considerations and there can be
no assurance that any of these strategies will succeed.
 
                                      10
<PAGE>
 
 INTEREST RATE SWAP TRANSACTIONS
 
  THE PORTFOLIO MAY ENTER INTO INTEREST RATE SWAPS. INTEREST RATE SWAPS
INVOLVE THE EXCHANGE BY THE PORTFOLIO WITH ANOTHER PARTY OF THEIR RESPECTIVE
COMMITMENTS TO PAY OR RECEIVE INTEREST, E.G., AN EXCHANGE OF FLOATING RATE
PAYMENTS FOR FIXED RATE PAYMENTS. The Portfolio expects to enter into these
transactions primarily to preserve a return or spread on a particular
investment or portion of its portfolio or to protect against any increase in
the price of securities the Portfolio anticipates purchasing at a later date.
The Portfolio intends to use these transactions as a hedge and not as a
speculative investment. See "Investment Objective and Policies--Other
Investments" in the Statement of Additional Information.
 
  The risk of loss with respect to interest rate swaps is limited to the net
amount of interest payments that the Portfolio is contractually obligated to
make and will not exceed 5% of the Portfolio's net assets. The use of interest
rate swaps may involve investment techniques and risks different from those
associated with ordinary portfolio transactions. If the investment adviser is
incorrect in its forecast of market values, interest rates and other
applicable factors, the investment performance of the Portfolio would diminish
compared to what it would have been if the investment technique was never
used.
 
 FUTURES CONTRACTS AND OPTIONS THEREON
 
  THE PORTFOLIO MAY PURCHASE AND SELL EURODOLLAR FUTURES CONTRACTS AND OPTIONS
THEREON WHICH ARE TRADED ON THE CHICAGO MERCANTILE EXCHANGE OR OTHER
COMMODITIES EXCHANGES OR BOARDS OF TRADE, FOR CERTAIN HEDGING, RETURN
ENHANCEMENT AND RISK MANAGEMENT PURPOSES IN ACCORDANCE WITH REGULATIONS OF THE
COMMODITY FUTURES TRADING COMMISSION.
 
  A FINANCIAL FUTURES CONTRACT IS AN AGREEMENT TO PURCHASE OR SELL AN AGREED
AMOUNT OF SECURITIES AT A SET PRICE FOR DELIVERY IN THE FUTURE. Eurodollar
futures contracts and options thereon are denominated in U.S. dollars and are
linked to the London Interbank Offered Rate (LIBOR). These futures contracts
and options thereon enable purchasers to obtain a fixed rate for the lending
of funds and sellers to obtain a fixed rate for borrowings. The Portfolio
intends to use Eurodollar futures contracts and options thereon to hedge
against changes in LIBOR, to which many interest rate swaps are linked.
 
  UNDER REGULATIONS OF THE COMMODITY EXCHANGE ACT, INVESTMENT COMPANIES
REGISTERED UNDER THE INVESTMENT COMPANY ACT ARE EXEMPT FROM THE DEFINITION OF
"COMMODITY POOL OPERATOR", SUBJECT TO COMPLIANCE WITH CERTAIN CONDITIONS. THE
EXEMPTION IS CONDITIONED ON THE PORTFOLIO PURCHASING AND SELLING FUTURES
CONTRACTS AND OPTIONS THEREIN FOR BONA FIDE HEDGING TRANSACTIONS, EXCEPT THAT
THE PORTFOLIO MAY PURCHASE AND SELL FUTURES CONTRACTS AND OPTIONS THEREON FOR
ANY OTHER PURPOSE TO THE EXTENT THAT THE AGGREGATE INITIAL MARGIN AND OPTION
PREMIUMS DO NOT EXCEED 5% OF THE LIQUIDATION VALUE OF THE PORTFOLIO'S TOTAL
ASSETS.
 
 RISKS OF HEDGING AND INCOME ENHANCEMENT STRATEGIES
 
  PARTICIPATION IN THE FUTURES MARKETS INVOLVES INVESTMENT RISKS AND
TRANSACTION COSTS TO WHICH THE PORTFOLIO WOULD NOT BE SUBJECT ABSENT THE USE
OF THIS STRATEGY. If the investment adviser's predictions of movements in the
direction of the securities and interest rate markets are inaccurate, the
adverse consequences to the Portfolio may leave the Portfolio in a worse
position than if such strategies were not used. Risks inherent in the use of
futures contracts and options on futures contracts include (1) dependence on
the investment adviser's ability to predict correctly movements in the
direction of interest rates and securities prices; (2) imperfect correlation
between the price of futures contracts and options thereon and movements in
the prices of the securities being hedged; (3) the fact that skills needed to
use these strategies are different from those needed to select portfolio
securities; (4) the possible absence of a liquid secondary market for any
particular instrument at any time; (5) the possible need to defer closing out
certain hedged positions to avoid adverse tax consequences; and (6) the
possible inability of the Portfolio to purchase or sell a portfolio security
at a time that otherwise would be favorable for it to do so, or the possible
need for the Portfolio to sell a portfolio security at a disadvantageous time,
due to the need for the Portfolio to maintain "cover" or to segregate
securities in connection with hedging transactions. See "Investment Objective
and Policies--Other Investments--Interest Rate Futures Contracts" and "Taxes"
in the Statement of Additional Information.
 
                                      11
<PAGE>
 
OTHER INVESTMENTS AND POLICIES
 
  Under normal market conditions, the assets of the Portfolio, other than
monies from recent investments in the Portfolio pending investment in
securities having laddered maturities, will be invested in U.S. Government
securities or corporate and other debt obligations, as described above. When
the investment adviser deems it necessary for defensive purposes, to provide
liquidity or pending investment in securities having laddered maturities, the
assets of the Portfolio may be committed temporarily to high quality money
market instruments or repurchase agreements, as described below.
 
  During periods when the investment adviser deems it necessary for temporary
defensive purposes, the Portfolio may invest without limit in money market
instruments. The Portfolio will apply the proceeds of new investments in the
Portfolio to purchase money market instruments and repurchase agreements until
these amounts can be used to purchase corporate and other debt obligations and
U.S. Government securities with laddered maturities of from one year or less
to six years. The yield on money market instruments and repurchase agreements
is generally lower than the yield on corporate and other debt obligations and
U.S. Government securities. Accordingly, the Portfolio's yield and total
return will generally be lower during these periods.
 
 MONEY MARKET INSTRUMENTS
 
  The Portfolio may invest in high quality money market instruments, including
commercial paper of a U.S. or foreign company or foreign government;
certificates of deposit, bankers' acceptances and time deposits of domestic
and foreign banks; and obligations issued or guaranteed by the U.S.
Government, its agencies and instrumentalities. These obligations will be U.S.
dollar-denominated. Commercial paper will be rated, at the time of purchase,
at least A-2 by S&P or Prime-2 by Moody's, or, if not rated, issued by an
entity having an outstanding unsecured debt issue rated at least A or A-2 by
S&P or A or Prime-2 by Moody's.
 
 REPURCHASE AGREEMENTS
 
  The Portfolio may on occasion enter into repurchase agreements whereby the
seller agrees to repurchase that security from the Portfolio at a mutually
agreed-upon time and price. The repurchase date is usually within a day or two
of the original purchase, although it may extend over a number of months. The
resale price is in excess of the purchase price, reflecting an agreed-upon
rate of return effective for the period of time the Portfolio's money is
invested in the security. The Portfolio's repurchase agreements will at all
times be fully collateralized in an amount at least equal to the purchase
price, including accrued interest earned on the underlying securities. The
instruments held as collateral are valued daily, and if the value of
instruments declines, the Portfolio will require additional collateral. If the
seller defaults and the value of the collateral securing the repurchase
agreement declines, the Portfolio may incur a loss. The Fund participates in a
joint repurchase account with other investment companies managed by Prudential
Mutual Fund Management, Inc. pursuant to an order of the SEC. See "Investment
Objective and Policies--Other Investments--Repurchase Agreements" in the
Statement of Additional Information.
 
 COVERED DOLLAR ROLLS
 
  The Portfolio may enter into covered dollar rolls. In a dollar roll, the
Portfolio sells securities for delivery in the current month and
simultaneously contracts to repurchase substantially similar (same type and
coupon) securities on a specified future date from the same party. During the
roll period, the Portfolio foregoes principal and interest paid on the
securities. The Portfolio is compensated by the difference between the current
sales price and the forward price for the future purchase (often referred to
as the "drop") as well as by the interest earned on the cash proceeds of the
initial sale. A "covered roll" is a specific type of dollar roll for which
there is an offsetting cash position or a cash equivalent security position
which matures on or before the forward settlement date of the dollar roll
transaction.
 
  The Portfolio will establish a segregated account with its Custodian in
which it will maintain cash, U.S. Government securities or other liquid high-
grade debt obligations equal in value to its obligations in respect of covered
dollar rolls. Covered dollar rolls involve the risk that the market value of
the securities retained by the Portfolio may decline below the price of the
securities the Portfolio has sold but is obligated to repurchase under the
agreement. In the event the buyer of
 
                                      12
<PAGE>
 
securities under a covered dollar roll files for bankruptcy or becomes
insolvent, the Portfolio's use of the proceeds of the agreement may be
restricted pending a determination by the other party, or its trustee or
receiver, whether to enforce the Portfolio's obligation to repurchase the
securities.
 
  The Portfolio may invest up to 5% of its assets in covered dollar rolls.
 
 SECURITIES LENDING
 
  The Portfolio may lend its portfolio securities to brokers or dealers, banks
or other recognized institutional borrowers of securities, provided that the
borrower at all times maintains cash or equivalent collateral or secures a
letter of credit in favor of the Portfolio in an amount equal to at least 100%
of the market value of the securities loaned. During the time portfolio
securities are on loan, the borrower will pay the Portfolio an amount
equivalent to any dividend or interest paid on such securities and the
Portfolio may invest the cash collateral and earn additional income, or it may
receive an agreed-upon amount of interest income from the borrower. As a
matter of fundamental policy, the Portfolio cannot lend more than 30% of the
value of its total assets.
 
 WHEN-ISSUED AND DELAYED DELIVERY SECURITIES
 
  The Portfolio may purchase or sell securities on a when-issued or delayed
delivery basis. When-issued or delayed delivery transactions arise when
securities are purchased or sold by the Portfolio with payment and delivery
taking place a month or more in the future in order to secure what is
considered to be an advantageous price and yield to the Portfolio at the time
of entering into the transaction. The Fund's Custodian will maintain, in a
segregated account of the Portfolio, cash, U.S. Government securities or other
liquid high-grade debt obligations having a value equal to or greater than the
Portfolio's purchase commitments; the Custodian will likewise segregate
securities sold on a delayed delivery basis. The securities so purchased are
subject to market fluctuation and no interest accrues to the purchaser during
the period between purchase and settlement. At the time of delivery of the
securities the value may be more or less than the purchase price and an
increase in the percentage of the Portfolio's assets committed to the purchase
of securities on a when-issued or delayed delivery basis may increase the
volatility of the Portfolio's net asset value.
 
 BORROWING
 
  The Portfolio may borrow an amount equal to no more than 20% of the value of
its total assets (computed at the time the loan is made) from banks for
temporary, extraordinary or emergency purposes. The Portfolio may pledge up to
20% of its total assets to secure these borrowings. However, the Portfolio
will not purchase portfolio securities if its borrowings exceed 5% of its net
assets.
 
 PORTFOLIO TURNOVER
 
  The Portfolio does not expect to trade in securities for short-term gain. It
is anticipated that the annual portfolio turnover rate will not exceed 200%.
High portfolio turnover may involve correspondingly greater transaction costs,
which will be borne by the Fund. The portfolio turnover rate is calculated by
dividing the lesser of sales or purchases of portfolio securities by the
average monthly value of the portfolio securities, excluding securities having
a maturity at the date of purchase of one year or less.
 
 ILLIQUID SECURITIES
 
  The Portfolio may invest up to 15% of its net assets in illiquid securities,
including repurchase agreements which have a maturity of longer than seven
days, securities with legal or contractual restrictions on resale (restricted
securities) and securities that are not readily marketable. Restricted
securities eligible for resale pursuant to Rule 144A under the Securities Act
of 1933, as amended (the Securities Act), and privately placed commercial
paper that have a readily available market are not considered illiquid for
purposes of this limitation. The investment adviser will monitor the liquidity
of such restricted securities under the supervision of the Board of Directors.
Repurchase agreements subject to demand are deemed to have a maturity equal to
the applicable notice period.
 
                                      13
<PAGE>
 
  The staff of the SEC has taken the position that purchased over-the-counter
options and the assets used as "cover" for written over-the-counter options
are illiquid securities unless the Portfolio and the counterparty have
provided for the Portfolio, at the Portfolio's election, to unwind the over-
the-counter option. The exercise of such an option ordinarily would involve
the payment by the Portfolio of an amount designed to reflect the
counterparty's economic loss from an early termination, but does allow the
Portfolio to treat the assets used as "cover" as "liquid."
 
INVESTMENT RESTRICTIONS
 
  The Portfolio is subject to certain investment restrictions which, like its
investment objective, constitute fundamental policies. Fundamental policies
cannot be changed without the approval of the holders of a majority of the
Portfolio's outstanding voting securities, as defined in the Investment
Company Act. See "Investment Restrictions" in the Statement of Additional
Information.

DISTRIBUTOR
 
  PRUDENTIAL MUTUAL FUND DISTRIBUTORS, INC. (PMFD), ONE SEAPORT PLAZA, NEW
YORK, NEW YORK 10292, IS A CORPORATION ORGANIZED UNDER THE LAWS OF THE STATE
OF DELAWARE AND SERVES AS THE DISTRIBUTOR OF THE CLASS A SHARES OF THE
PORTFOLIO. IT IS A WHOLLY-OWNED SUBSIDIARY OF PMF.
 
  PRUDENTIAL SECURITIES INCORPORATED (PRUDENTIAL SECURITIES OR PSI), ONE
SEAPORT PLAZA, NEW YORK, NEW YORK 10292, IS A CORPORATION ORGANIZED UNDER THE
LAWS OF THE STATE OF DELAWARE AND SERVES AS THE DISTRIBUTOR OF THE CLASS B AND
CLASS C SHARES OF THE PORTFOLIO. IT IS AN INDIRECT, WHOLLY-OWNED SUBSIDIARY OF
PRUDENTIAL.
 
  UNDER SEPARATE DISTRIBUTION AND SERVICE PLANS (THE CLASS A PLAN, THE CLASS B
PLAN AND THE CLASS C PLAN, COLLECTIVELY, THE PLANS) ADOPTED BY THE FUND UNDER
RULE 12B-1 UNDER THE INVESTMENT COMPANY ACT AND SEPARATE DISTRIBUTION
AGREEMENTS (THE DISTRIBUTION AGREEMENTS), PMFD AND PRUDENTIAL SECURITIES
(COLLECTIVELY, THE DISTRIBUTOR) INCUR THE EXPENSES OF DISTRIBUTING THE
PORTFOLIO'S CLASS A, CLASS B AND CLASS C SHARES. These expenses include
commissions and account servicing fees paid to, or on account of, financial
advisers of Prudential Securities and representatives of Pruco Securities
Corporation (Prusec), affiliated broker-dealers, commissions and account
servicing fees paid to, or on account of, other broker-dealers or financial
institutions (other than national banks) which have entered into agreements
with the Distributor, advertising expenses, the cost of printing and mailing
prospectuses to potential investors and indirect and overhead costs of
Prudential Securities and Prusec associated with the sale of Portfolio shares,
including lease, utility, communications and sales promotion expenses. The
State of Texas requires that shares of the Portfolio may be sold in that state
only by dealers or other financial institutions which are registered there as
broker-dealers.
 
  Under the Plans, the Portfolio is obligated to pay distribution and/or
service fees to the Distributor as compensation for its distribution and
service activities, not as reimbursement for specific expenses incurred. If
the Distributor's expenses exceed its distribution and service fees, the
Portfolio will not be obligated to pay any additional expenses. If the
Distributor's expenses are less than such distribution and service fees, it
will retain its full fees and realize a profit.
 
  UNDER THE CLASS A PLAN, THE PORTFOLIO MAY PAY PMFD FOR ITS DISTRIBUTION-
RELATED ACTIVITIES WITH RESPECT TO CLASS A SHARES AT AN ANNUAL RATE OF UP TO
.30 OF 1% OF THE AVERAGE DAILY NET ASSETS OF THE CLASS A SHARES. The Class A
Plan provides that: (i) up to .25 of 1% of the average daily net assets of the
Class A shares may be used to pay for personal service and/or the maintenance
of shareholder accounts (service fee) and (ii) total distribution fees
(including the service fee of .25 of 1%) may not exceed .30 of 1% of the
average daily net assets of the Class A shares. PMFD has agreed to limit its
distribution-related fees payable under the Class A Plan to .10 of 1% of the
average daily net assets of the Class A shares for the fiscal year ending
December 31, 1994.
 
  For the fiscal year ended December 31, 1993, PMFD received payments of
$114,728 under the Class A Plan. This amount was primarily expended for
payment of account servicing fees to financial advisers and other persons who
sell Class A shares. For the fiscal year ended December 31, 1993, PMFD also
received approximately $669,100 in initial sales charges.
 
  UNDER THE CLASS B AND CLASS C PLANS, THE PORTFOLIO MAY PAY PRUDENTIAL
SECURITIES FOR ITS DISTRIBUTION-RELATED ACTIVITIES WITH RESPECT TO CLASS B AND
CLASS C SHARES AT AN ANNUAL RATE OF 1% OF THE AVERAGE DAILY NET ASSETS OF EACH
OF THE CLASS B AND CLASS C SHARES. The Class B and Class C Plans provide for
the payment to Prudential Securities of (i) an asset-based sales charge of .75
of 1% of the average daily net assets of each of the Class B and Class C
shares, and (ii) a service fee of .25 of 1% of the average daily net assets of
each of the Class B and Class C shares. The service fee is used to pay for
personal service and/or the maintenance of shareholder accounts. Prudential
Securities has agreed to limit its distribution-related fees payable under the
Class B and Class C Plans to no more than .75 of 1% of the average daily net
 
                                      15
<PAGE>
 
assets of each of the Class B and Class C shares for the fiscal year ending
December 31, 1994. Prudential Securities also receives contingent deferred
sales charges from certain redeeming shareholders. See "Shareholder Guide--How
to Sell Your Shares--Contingent Deferred Sales Charges."
 
  For the fiscal year ended December 31, 1993, Prudential Securities incurred
distribution expenses of approximately $2,786,300 under the Class B Plan and
received $589,173 from the Portfolio under the Class B Plan. In addition,
Prudential Securities received approximately $86,000 in contingent deferred
sales charges from redemptions of Class B shares during this period. No Class
C shares were outstanding during the fiscal year ended December 31, 1993.
 
  For the fiscal year ended December 31, 1993, the Portfolio paid distribution
expenses of .10% and .85% of the average daily net assets of the Class A and
Class B shares, respectively. The Portfolio records all payments made under
the Plans as expenses in the calculation of net investment income. No Class C
shares were outstanding during the fiscal year ended December 31, 1993. Prior
to the date of this Prospectus, the Class A and Class B Plans operated as
"reimbursement type" plans and, in the case of Class B, provided for the
reimbursement of distribution expenses incurred in current and prior years.
See "Distributor" in the Statement of Additional Information.
 
  Distribution expenses attributable to the sale of shares of the Portfolio
will be allocated to each class based upon the ratio of sales of each class to
the sales of all shares of the Portfolio other than expenses allocable to a
particular class. The distribution fee and sales charge of one class will not
be used to subsidize the sale of another class.
 
  Each Plan provides that it shall continue in effect from year to year
provided that a majority of the Board of Directors of the Fund, including a
majority of the Directors who are not "interested persons" of the Fund (as
defined in the Investment Company Act) and who have no direct or indirect
financial interest in the operation of the Plan or any agreement related to
the Plan (the Rule 12b-1 Directors), vote annually to continue the Plan. Each
Plan may be terminated at any time by vote of a majority of the Rule 12b-1
Directors or of a majority of the outstanding shares of the applicable class
of the Portfolio. The Portfolio will not be obligated to pay expenses incurred
under any plan if it is terminated or not continued.
 
  In addition to distribution and service fees paid by the Portfolio under the
Class A, Class B and Class C Plans, the Manager (or one of its affiliates) may
make payments out of its own resources to dealers and other persons who
distribute shares of the Portfolio. Such payments may be calculated by
reference to the net asset value of shares sold by such persons or otherwise.
 
  The Distributor is subject to the rules of the National Association of
Securities Dealers, Inc. governing maximum sales charges. See "Distributor" in
the Statement of Additional Information.

  Prudential Securities may also act as a broker or futures commission
merchant for the Portfolio, provided that the commissions, fees or other
remuneration it receives are fair and reasonable. See "Portfolio Transactions

<PAGE>
 
 
                        HOW THE FUND VALUES ITS SHARES
 
 
  THE PORTFOLIO'S NET ASSET VALUE PER SHARE OR NAV IS DETERMINED BY
SUBTRACTING ITS LIABILITIES FROM THE VALUE OF ITS ASSETS AND DIVIDING THE
REMAINDER BY THE NUMBER OF OUTSTANDING SHARES. NAV IS CALCULATED SEPARATELY
FOR EACH CLASS. THE BOARD OF DIRECTORS HAS FIXED THE SPECIFIC TIME OF DAY FOR
THE COMPUTATION OF THE PORTFOLIO'S NAV TO BE AS OF 4:15 P.M., NEW YORK TIME.
 
  Portfolio securities are valued based on market quotations or, if not
readily available, at fair value as determined in good faith under procedures
established by the Fund's Board of Directors. See "Net Asset Value" in the
Statement of Additional Information.
 
  The Portfolio will compute its NAV once daily on days that the New York
Stock Exchange is open for trading except on days on which no orders to
purchase, sell or redeem shares have been received by the Fund or days on
which changes in the value of the Fund's portfolio securities do not
materially affect the NAV. The New York Stock Exchange is closed on the
following holidays: New Year's Day, Presidents' Day, Good Friday, Memorial
Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day.
 
  Although the legal rights of each class of shares are substantially
identical, the different expenses borne by each class will result in different
NAVs and dividends. The NAV of Class B and Class C shares will generally be
lower than the NAV of Class A shares as a result of the larger distribution-
related fee to which Class B and Class C shares are subject. It is expected,
however, that the NAV of the three classes will tend to converge immediately
after the recording of dividends, which will differ by approximately the
amount of the distribution-related expense accrual differential among the
classes.
 
 
                      HOW THE FUND CALCULATES PERFORMANCE
 
 
  FROM TIME TO TIME THE PORTFOLIO MAY ADVERTISE ITS "YIELD" AND "TOTAL RETURN"
(INCLUDING "AVERAGE ANNUAL" TOTAL RETURN AND "AGGREGATE" TOTAL RETURN) IN
ADVERTISEMENTS OR SALES LITERATURE. YIELD AND TOTAL RETURN ARE CALCULATED
SEPARATELY FOR CLASS A, CLASS B AND CLASS C SHARES. These figures are based on
historical earnings and are not intended to indicate future performance. The
"yield" refers to the income generated by an investment in the Portfolio over
a one-month or 30-day period. This income is then "annualized;" that is, the
amount of income generated by the investment during that 30-day period is
assumed to be generated each 30-day period for twelve periods and is shown as
a percentage of the investment. The income earned on the investment is also
assumed to be reinvested at the end of the sixth 30-day period. The "total
return" shows how much an investment in the Portfolio would have increased
(decreased) over a specified period of time (i.e., one, five or ten years or
since inception of the Portfolio) assuming that all distributions and
dividends by the Portfolio were reinvested on the reinvestment dates during
the period and less all recurring fees. The "aggregate" total return reflects
actual performance over a stated period of time. "Average annual" total return
is a hypothetical rate of return that, if achieved annually, would have
produced the same aggregate total return if performance had been constant over
the entire period. "Average annual" total return smooths out variations in
performance and takes into account any applicable initial or contingent
deferred sales charges. Neither "average annual" total return nor "aggregate"
total return takes into account any federal or state income taxes that may be
payable upon redemption. The Fund also may include comparative performance
information in advertising or marketing the shares of the Portfolio. Such
performance information may include data from Lipper Analytical Services,
Inc., Morningstar Publications, Inc., other industry publications, business
periodicals and market indices. See "Performance Information" in the Statement
of Additional Information. The Portfolio will include performance data for
each class of shares of the Portfolio in any advertisement or information
including performance data of the Portfolio. Further performance information
is contained in the Fund's annual and semi-annual reports to shareholders,
which may be obtained without charge. See "Shareholder Guide--Shareholder
Services--Reports to Shareholders."

                      TAXES, DIVIDENDS AND DISTRIBUTIONS
 
 
TAXATION OF THE FUND
 
  THE PORTFOLIO HAS ELECTED TO QUALIFY AND INTENDS TO REMAIN QUALIFIED AS A
REGULATED INVESTMENT COMPANY UNDER THE INTERNAL REVENUE CODE OF 1986, AS
AMENDED (THE INTERNAL REVENUE CODE). ACCORDINGLY, THE PORTFOLIO WILL NOT BE
SUBJECT TO FEDERAL INCOME TAXES ON ITS NET INVESTMENT INCOME AND CAPITAL
GAINS, IF ANY, THAT IT DISTRIBUTES TO ITS SHAREHOLDERS. To the extent not
distributed by the Portfolio, net investment income and capital gains and
losses are taxable to the Portfolio. See "Taxes" in the Statement of
Additional Information.
 
TAXATION OF SHAREHOLDERS
 
  All dividends out of net investment income, together with distributions of
net short-term capital gains, will be taxable as ordinary income to the
shareholder whether or not reinvested. Any net capital gains (i.e. the excess
of net long-term capital gains over net short-term capital losses) distributed
to shareholders will be taxable as long-term capital gains to the
shareholders, whether or not reinvested and regardless of the length of time a
shareholder has owned his or her shares. The maximum long-term capital gains
rate for individuals is 28%. The maximum long-term capital gains rate for
corporate shareholders is currently the same as the maximum tax rate for
ordinary income.
 
  Dividends paid by the Portfolio will be eligible for the 70% dividends-
received deduction for corporate shareholders to the extent that the
Portfolio's income is derived from certain dividends paid by domestic
corporations. Capital gains distributions are not eligible for the 70%
dividends received deduction.
 
  Any gain or loss realized upon a sale or redemption of Portfolio shares by a
shareholder who is not a dealer in securities will be treated as long-term
capital gain or loss if the shares have been held for more than one year and
otherwise as short-term capital gain or loss. Any such loss, however, on
shares that are held for six months or less will be treated as long-term
capital loss to the extent of any capital gain distributions received by the
shareholder.
 
  The Fund has obtained opinions of counsel to the effect that neither (i) the
conversion of Class B shares into Class A shares nor (ii) the exchange of
Class B or Class C shares for Class A shares constitutes a taxable event for
federal income tax purposes. However, such opinions are not binding on the
Internal Revenue Service.
 
  Shareholders are advised to consult their own tax advisers regarding
specific questions as to federal, state or local taxes.
 
WITHHOLDING TAXES
 
  Under the Internal Revenue Code, the Portfolio is required to withhold and
remit to the U.S. Treasury 31% of dividends, capital gain income and
redemption proceeds payable to individuals and certain non corporate
shareholders who fail to furnish correct tax identification numbers on IRS
Form W-9 (or IRS Form W-8 in the case of certain foreign shareholders).
Dividends of net investment income and net short-term capital gains paid to a
foreign shareholder will generally be subject to U.S. withholding tax at the
rate of 30% (or lower treaty rate).
 
DIVIDENDS AND DISTRIBUTIONS
 
  THE PORTFOLIO EXPECTS TO DECLARE DAILY AND PAY MONTHLY DIVIDENDS OF NET
INVESTMENT INCOME, IF ANY, AND MAKE DISTRIBUTIONS AT LEAST ANNUALLY OF ANY NET
CAPITAL GAINS. Dividends paid by the Portfolio with respect to each class of
shares, to the extent any dividends are paid, will be calculated in the same
manner, at the same time, on the same day and will be in the same amount
except that each class will bear its own distribution charges, generally
resulting in lower dividends for Class B and Class C shares. Distributions of
net capital gains, if any, will be paid in the same amount for each class of
shares. See "How the Fund Values its Shares."
 
                                      18
<PAGE>
 
  DIVIDENDS AND DISTRIBUTIONS WILL BE PAID IN ADDITIONAL PORTFOLIO SHARES, AT
THE NAV ON THE PAYMENT DATE UNLESS THE SHAREHOLDER ELECTS IN WRITING NOT LESS
THAN FIVE BUSINESS DAYS PRIOR TO THE PAYMENT DATE TO RECEIVE SUCH DIVIDENDS
AND DISTRIBUTIONS IN CASH. The Board of Directors reserves the right to change
the reinvestment date from the payment date to the record date for certain
capital gains distributions. Such election should be submitted to Prudential
Mutual Fund Services, Inc., Attention: Account Maintenance, P.O. Box 15015,
New Brunswick, New Jersey 08906-5015. If you hold shares through Prudential
Securities you should contact your financial adviser to elect to receive
dividends and distributions in cash. The Fund will notify each shareholder
after the close of the Fund's taxable year both of the dollar amount and the
taxable status of that year's dividends and distributions on a per share
basis.
 
  WHEN THE PORTFOLIO GOES "EX-DIVIDEND," ITS NAV IS REDUCED BY THE AMOUNT OF
THE DIVIDEND OR DISTRIBUTION. IF YOU BUY SHARES JUST PRIOR TO THE EX-DIVIDEND
DATE FOR A CAPITAL GAIN DISTRIBUTION, THE PRICE YOU PAY WILL INCLUDE THE
DISTRIBUTION AND A PORTION OF YOUR INVESTMENT WILL BE RETURNED TO YOU AS A
TAXABLE DISTRIBUTION. YOU SHOULD, THEREFORE, CONSIDER THE TIMING OF CAPITAL
GAIN DISTRIBUTIONS WHEN MAKING YOUR PURCHASES.
 
 
                              GENERAL INFORMATION
 
 
DESCRIPTION OF COMMON STOCK
 
  THE FUND WAS INCORPORATED IN MARYLAND ON JUNE 8, 1988. THE FUND IS
AUTHORIZED TO ISSUE 500 MILLION SHARES OF COMMON STOCK, $.01 PAR VALUE PER
SHARE, DIVIDED INTO THREE CLASSES FOR EACH PORTFOLIO, DESIGNATED CLASS A,
CLASS B AND CLASS C COMMON STOCK, EACH OF WHICH CONSISTS OF 83,333,333 1/3
AUTHORIZED SHARES. Each class of common stock represents an interest in the
same assets of the Portfolio and is identical in all respects except that (i)
each class bears different distribution expenses, (ii) each class has
exclusive voting rights with respect to its distribution and service plan
(except that the Fund has agreed with the SEC in connection with the offering
of a conversion feature on Class B shares to submit any amendment of the Class
A Plan to both Class A and Class B shareholders), (iii) each class has a
different exchange privilege and (iv) only Class B shares have a conversion
feature. See "How the Fund is Managed--Distributor." The Fund has received an
order from the SEC permitting the issuance and sale of multiple classes of
common stock. Currently, the Portfolio is offering three classes, designated
Class A, Class B and Class C shares. In accordance with the Fund's Articles of
Incorporation, the Board of Directors may authorize the creation of additional
series of common stock and classes within such series, with such preferences,
privileges, limitations and voting and dividend rights as the Board of
Directors may determine.
 
  The Board of Directors may increase or decrease the number of authorized
shares without approval by the shareholders. Shares of the Fund, when issued,
are fully paid, nonassessable, fully transferable and redeemable at the option
of the holder. Shares are also redeemable at the option of the Fund under
certain circumstances as described under "Shareholder Guide--How to Sell Your
Shares." Each share of each class of common stock of the Portfolio is equal as
to earnings, assets and voting privileges, except as noted above, and each
class bears the expenses related to the distribution of its shares. Except for
the conversion feature applicable to the Class B shares, there are no
conversion, preemptive or other subscription rights. In the event of
liquidation, each share of common stock of each Portfolio is entitled to its
portion of all of the Portfolio's assets after all debt and expenses of the
Portfolio have been paid. Since Class B and Class C shares generally bear
higher distribution expenses than Class A shares, the liquidation proceeds to
shareholders of those classes are likely to be lower than to Class A
shareholders. The Fund's shares do not have cumulative voting rights for the
election of Directors.
 
  THE FUND DOES NOT INTEND TO HOLD SHAREHOLDERS MEETINGS UNLESS OTHERWISE
REQUIRED BY LAW. THE FUND WILL NOT BE REQUIRED TO HOLD MEETINGS OF
SHAREHOLDERS UNLESS, FOR EXAMPLE, THE ELECTION OF DIRECTORS IS REQUIRED TO BE
ACTED ON BY SHAREHOLDERS UNDER THE INVESTMENT COMPANY ACT. SHAREHOLDERS HAVE
CERTAIN RIGHTS, INCLUDING THE RIGHT TO CALL A MEETING UPON A VOTE OF 10% OF
THE FUND'S OUTSTANDING SHARES FOR THE PURPOSE OF VOTING ON THE REMOVAL OF ONE
OR MORE DIRECTORS OR TO TRANSACT ANY OTHER BUSINESS.

  The three classes of shares represent an interest in the same portfolio of
investments of the Portfolio and have the same rights, except that (i) each
class bears the separate expenses of its Rule 12b-1 distribution and service
plan, (ii) each class has exclusive voting rights with respect to its plan
(except as noted under the heading "General Information--Description of Common
Stock"), and (iii) only Class B shares have a conversion feature. The three
classes also have separate exchange privileges. See "How to Exchange Your
Shares" below. The income attributable to each class and the dividends payable
on the shares of each class will be reduced by the amount of the distribution
fee of each class. Class B and Class C shares bear the expenses of a higher
distribution fee which will generally cause them to have higher expense ratios
and to pay lower dividends than the Class A shares.
 
  Financial advisers and other sales agents who sell shares of the Portfolio
will receive different compensation for selling Class A, Class B and Class C
shares and will generally receive more compensation initially for selling
Class A and Class B shares than for selling Class C shares.
 
  IN SELECTING A PURCHASE ALTERNATIVE, YOU SHOULD CONSIDER, AMONG OTHER
THINGS, (1) the length of time you expect to hold your investment, (2) the
amount of any applicable sales charge (whether imposed at the time of purchase
or redemption) and distribution-related fees, as noted above, (3) whether you
qualify for any reduction or waiver of any applicable sales charge, (4) the
various exchange privileges among the different classes of shares (see "How to
Exchange Your Shares" below) and (5) the fact that Class B shares
automatically convert to Class A shares approximately five years after
purchase (see "Conversion Feature--Class B Shares" below).
 
  The following is provided to assist you in determining which method of
purchase best suits your individual circumstances and is based on current fees
and expenses being charged to the Portfolio:
 
  If you intend to hold your investment in the Fund for less than 5 years and
do not qualify for a reduced sales charge on Class A shares since Class A
shares are subject to a maximum initial sales charge of 3.25% and Class B
shares are
 
                                      21
<PAGE>
 
subject to a CDSC of 3% which declines to zero over a 4 year period, you
should consider purchasing Class C shares over either Class A or Class B
shares.
 
  If you intend to hold your investment for 5 years or more and do not qualify
for a reduced sales charge on Class A shares, since Class B shares convert to
Class A shares approximately 5 years after purchase and because all of your
money would be invested initially in the case of Class B shares, you should
consider purchasing Class B shares over either Class A or Class C shares.
 
  If you qualify for a reduced sales charge on Class A shares, it may be more
advantageous for you to purchase Class A shares over either Class B or Class C
shares regardless of how long you intend to hold your investment. However,
unlike Class B and Class C shares, you would not have all of your money
invested initially because the sales charge on Class A shares is deducted at
the time of purchase.
 
  If you do not qualify for a reduced sales charge on Class A shares and you
purchase Class B or Class C shares, you would have to hold your investment for
more than 4 years in the case of Class B shares and Class C shares for the
higher cumulative annual distribution-related fee on those shares to exceed
the initial sales charge plus cumulative annual distribution-related fees on
Class A shares. This does not take into account the time value of money, which
further reduces the impact of the higher Class B or Class C distribution-
related fee on the investment, fluctuations in net asset value, the effect of
the return on the investment over this period of time or redemptions during
the period in which the CDSC is applicable.
 
  ALL PURCHASES OF $1 MILLION OR MORE, EITHER AS PART OF A SINGLE INVESTMENT
OR UNDER RIGHTS OF ACCUMULATION OR LETTERS OF INTENT, MUST BE FOR CLASS A
SHARES. SEE "REDUCTION AND WAIVER OF INITIAL SALES CHARGES" BELOW.
 
  CLASS A SHARES
 
  The offering price of Class A shares for investors choosing the initial
sales charge alternative is the next determined NAV plus a sales charge
(expressed as a percentage of the offering price and of the amount invested),
as shown in the following table:

  REDUCTION AND WAIVER OF INITIAL SALES CHARGES. Reduced sales charges are
available through Rights of Accumulation and Letters of Intent. Shares of the
Fund and shares of other Prudential Mutual Funds (excluding money market funds
other than those acquired pursuant to the exchange privilege) may be
aggregated to determine the applicable reduction. See "Purchase and Redemption
of Fund Shares--Reduction and Waiver of Initial Sales Charges--Class A Shares"
in the Statement of Additional Information.
 
  Benefit Plans. CLASS A SHARES MAY BE PURCHASED AT NAV, WITHOUT PAYMENT OF AN
INITIAL SALES CHARGE, BY PENSION, PROFIT-SHARING OR OTHER EMPLOYEE BENEFIT
PLANS QUALIFIED UNDER SECTION 401 OF THE INTERNAL REVENUE CODE AND DEFERRED
COMPENSATION AND ANNUITY PLANS UNDER SECTIONS 457 AND 403(B)(7) OF THE
INTERNAL REVENUE CODE (BENEFIT PLANS), PROVIDED THAT THE PLAN HAS EXISTING
ASSETS OF AT LEAST $1 MILLION INVESTED IN SHARES OF PRUDENTIAL MUTUAL FUNDS
(EXCLUDING MONEY MARKET FUNDS OTHER
 
                                      22

than those acquired pursuant to the exchange privilege) or 1,000 eligible
employees or members. In the case of Benefit Plans whose accounts are held
directly with the Transfer Agent or Prudential Securities and for which the
Transfer Agent or Prudential Securities does individual account recordkeeping
(Direct Account Benefit Plans) and Benefit Plans sponsored by PSI or its
subsidiaries (PSI or Subsidiary Prototype Benefit Plans), Class A shares may
be purchased at NAV by participants who are repaying loans made from such
plans to the participant.
 
  Prudential Retirement Accumulation Program 401(k) Plan. Class A shares may
be purchased at net asset value, with a waiver of the initial sales charge, by
or on behalf of participants in the Prudential Retirement Accumulation Program
401(k) Plan for which the Transfer Agent or Prudential Securities provides
recordkeeping services (PruRap Plan) provided that (i) for existing plans, the
plan has existing assets of $1 million or more, as measured on the last
business day of the month, invested in shares of Prudential Mutual Funds
(excluding money market funds other than those acquired pursuant to the
exchange privilege) held at the Transfer Agent or Prudential Securities and
(ii) for new plans, the plan initially invests $1 million or more in shares of
non-money market Prudential Mutual Funds or has at least 1,000 eligible
employees or members.
 
  Special Rules Applicable to Retirement Plans. After a Benefit Plan or the
PruRap Plan qualifies to purchase Class A shares at NAV, all subsequent
purchases will be made at NAV.
 
  Miscellaneous Waivers. In addition, Class A shares may be purchased at NAV,
through Prudential Securities or the Transfer Agent, by the following persons:
(a) Directors and officers of the Fund and other Prudential Mutual Funds, (b)
employees of Prudential Securities and PMF and their subsidiaries and members
of the families of such persons who maintain an "employee related" account at
Prudential Securities or the Transfer Agent, (c) employees and special agents
of Prudential and its subsidiaries and all persons who have retired directly
from active service with Prudential or one of its subsidiaries, (d) registered
representatives and employees of dealers who have entered into a selected
dealer agreement with Prudential Securities provided that purchases at NAV are
permitted by such person's employer and (e) investors who have a business
relationship with a financial adviser who joined Prudential Securities from
another investment firm, provided that (i) the purchase is made within 90 days
of the commencement of the financial adviser's employment at Prudential
Securities, (ii) the purchase is made with proceeds of a redemption of shares
of any open-end, non-money market fund sponsored by the financial adviser's
previous employer (other than a fund which imposes a distribution or service
fee of .25 of 1% or less) on which no deferred sales load, fee or other charge
was imposed on redemption and (iii) the financial adviser served as the
client's broker on the previous purchases.
 
  You must notify the Fund's Transfer Agent either directly or through
Prudential Securities or Prusec that you are entitled to the reduction or
waiver of the sales charge. The reduction or waiver will be granted subject to
confirmation of your entitlement. No initial sales charges are imposed upon
Class A shares acquired upon the reinvestment of dividends and distributions.
See "Purchase and Redemption of Fund Shares--Reduction and Waiver of Initial
Sales Charges--Class A Shares" in the Statement of Additional Information.
 
  CLASS B AND CLASS C SHARES
 
  The offering price of Class B and Class C shares for investors choosing one
of the deferred sales charge alternatives is the NAV next determined following
receipt of an order by the Transfer Agent or Prudential Securities. Although
there is no sales charge imposed at the time of purchase, redemptions of Class
B and Class C shares may be subject to a CDSC. See "How to Sell Your Shares--
Contingent Deferred Sales Charges."
 
HOW TO SELL YOUR SHARES
 
  YOU CAN REDEEM YOUR SHARES AT ANY TIME FOR CASH AT THE NAV NEXT DETERMINED
AFTER THE REDEMPTION REQUEST IS RECEIVED IN PROPER FORM BY THE TRANSFER AGENT
OR PRUDENTIAL SECURITIES. SEE "HOW THE FUND VALUES ITS SHARES." In
 
                                      23
<PAGE>
 
certain cases, however, redemption proceeds will be reduced by the amount of
any applicable contingent deferred sales charge, as described below. See
"Contingent Deferred Sales Charges" below.
 
  IF YOU HOLD SHARES OF THE PORTFOLIO THROUGH PRUDENTIAL SECURITIES, YOU MUST
REDEEM YOUR SHARES BY CONTACTING YOUR PRUDENTIAL SECURITIES FINANCIAL ADVISER.
IF YOU HOLD SHARES IN NON-CERTIFICATE FORM, A WRITTEN REQUEST FOR REDEMPTION
SIGNED BY YOU EXACTLY AS THE ACCOUNT IS REGISTERED IS REQUIRED. IF YOU HOLD
CERTIFICATES, THE CERTIFICATES, SIGNED IN THE NAME(S) SHOWN ON THE FACE OF THE
CERTIFICATES, MUST BE RECEIVED BY THE TRANSFER AGENT IN ORDER FOR THE
REDEMPTION REQUEST TO BE PROCESSED. IF REDEMPTION IS REQUESTED BY A
CORPORATION, PARTNERSHIP, TRUST OR FIDUCIARY, WRITTEN EVIDENCE OF AUTHORITY
ACCEPTABLE TO THE TRANSFER AGENT MUST BE SUBMITTED BEFORE SUCH REQUEST WILL BE
ACCEPTED. All correspondence and documents concerning redemptions should be
sent to the Fund in care of its Transfer Agent, Prudential Mutual Fund
Services, Inc., Attention: Redemption Services, P.O. Box 15010, New Brunswick,
New Jersey 08906-5010.
 
  If the proceeds of the redemption (a) exceed $50,000, (b) are to be paid to
a person other than the record owner, (c) are to be sent to an address other
than the address on the Transfer Agent's records, or (d) are to be paid to a
corporation, partnership, trust or fiduciary, the signature(s) on the
redemption request and on the certificates, if any, or stock power must be
guaranteed by an "eligible guarantor institution." An "eligible guarantor
institution" includes any bank, broker, dealer or credit union. The Transfer
Agent reserves the right to request additional information from, and make
reasonable inquires of, any eligible guarantor institution. For clients of
Prusec, a signature guarantee may be obtained from the agency or office
manager of most Prudential Insurance and Financial Services or Preferred
Services offices.
 
  PAYMENT FOR SHARES PRESENTED FOR REDEMPTION WILL BE MADE BY CHECK WITHIN
SEVEN DAYS AFTER RECEIPT BY THE TRANSFER AGENT OF THE CERTIFICATE AND/OR
WRITTEN REQUEST, EXCEPT AS INDICATED BELOW. IF YOU HOLD SHARES THROUGH
PRUDENTIAL SECURITIES, PAYMENT FOR SHARES PRESENTED FOR REDEMPTION WILL BE
CREDITED TO YOUR PRUDENTIAL SECURITIES ACCOUNT, UNLESS YOU INDICATE OTHERWISE.
Such payment may be postponed or the right of redemption suspended at times
(a) when the New York Stock Exchange is closed for other than customary
weekends and holidays, (b) when trading on such Exchange is restricted, (c)
when an emergency exists as a result of which disposal by the Fund of
securities owned by it is not reasonably practicable or it is not reasonably
practicable for the Fund fairly to determine the value of its net assets, or
(d) during any other period when the SEC, by order, so permits; provided that
applicable rules and regulations of the SEC shall govern as to whether the
conditions prescribed in (b), (c) or (d) exist.
 
  PAYMENT FOR REDEMPTION OF RECENTLY PURCHASED SHARES WILL BE DELAYED UNTIL
THE FUND OR ITS TRANSFER AGENT HAS BEEN ADVISED THAT THE PURCHASE CHECK HAS
BEEN HONORED, UP TO 10 CALENDAR DAYS FROM THE TIME OF RECEIPT OF THE PURCHASE
CHECK BY THE TRANSFER AGENT. SUCH DELAY MAY BE AVOIDED BY PURCHASING SHARES BY
WIRE OR BY CERTIFIED OR OFFICIAL BANK CHECK.
 
  REDEMPTION IN KIND. If the Board of Directors determines that it would be
detrimental to the best interests of the remaining shareholders of the Fund to
make payments wholly or partly in cash, the Fund may pay the redemption price
in whole or in part by a distribution in kind of securities from the
investment portfolio of the Fund, in lieu of cash, in conformity with
applicable rules of the SEC. Securities will be readily marketable and will be
valued in the same manner as in a regular redemption. See "How the Fund Values
its Shares." If your shares are redeemed in kind, you would incur transaction
costs in converting the assets into cash. The Fund, however, has elected to be
governed by Rule 18f-1 under the Investment Company Act, under which the Fund
is obligated to redeem shares solely in cash up to the lesser of $250,000 or
1% of the net asset value of the Fund during any 90-day period for any one
shareholder.
 
  INVOLUNTARY REDEMPTION. In order to reduce expenses of the Fund, the Board
of Directors may redeem all of the shares of any shareholder, other than a
shareholder which is an IRA or other tax-deferred retirement plan, whose
account has a net asset value of less than $500 due to a redemption. The Fund
will give such shareholders 60 days' prior written notice in which to purchase
sufficient additional shares to avoid such redemption. No contingent deferred
sales charge will be imposed on any involuntary redemption.
 
  30-DAY REPURCHASE PRIVILEGE. If you redeem your shares and have not
previously exercised the repurchase privilege, you may reinvest any portion or
all of the proceeds of such redemption in shares of the Portfolio at the NAV
next determined
 
                                      24
<PAGE>
 
after the order is received, which must be within 30 days after the date of
the redemption. No sales charge will apply to such repurchases. You will
receive pro rata credit for any contingent deferred sales charge paid in
connection with the redemption of Class B or Class C shares. You must notify
the Fund's Transfer Agent, either directly or through Prudential Securities or
Prusec, at the time the repurchase privilege is exercised that you are
entitled to credit for the contingent deferred sales charge previously paid.
Exercise of the repurchase privilege will generally not affect federal income
tax treatment of any gain realized upon redemption. If the redemption resulted
in a loss, some or all of the loss, depending on the amount reinvested, will
not be allowed for federal income tax purposes.
 
 CONTINGENT DEFERRED SALES CHARGES
 
  Redemptions of Class B shares will be subject to a contingent deferred sales
charge or CDSC declining from 3% to zero over a four year period. Class C
shares redeemed within one year of purchase will be subject to a 1% CDSC. The
CDSC will be deducted from the redemption proceeds and reduce the amount paid
to you. The CDSC will be imposed on any redemption by you which reduces the
current value of your Class B or Class C shares to an amount which is lower
than the amount of all payments by you for shares during the preceding four
years, in the case of Class B shares, and one year, in the case of Class C
shares. A CDSC will be applied on the lesser of the original purchase price or
the current value of the shares being redeemed. Increases in the value of your
shares or shares acquired through reinvestment of dividends or distributions
are not subject to a CDSC. The amount of any contingent deferred sales charge
will be paid to and retained by the Distributor. See "How the Fund is
Managed--Distributor" and "Waiver of the Contingent Deferred Sales Charges--
Class B Shares" below.
 
  The amount of the CDSC, if any, will vary depending on the number of years
from the time of payment for the purchase of shares until the time of
redemption of such shares. Solely for purposes of determining the number of
years from the time of any payment for the purchase of shares, all payments
during a month will be aggregated and deemed to have been made on the last day
of the month.The CDSC will be calculated from the first day of the month after
the initial purchase, excluding the time shares were held in a money market
fund. See "How to Exchange Your Shares."
 
  The following table sets forth the rates of the CDSC applicable to
redemptions of Class B shares:

        Fourth........................................           1.0%
        Fifth and thereafter..........................           None
</TABLE>
 
  In determining whether a CDSC is applicable to a redemption, the calculation
will be made in a manner that results in the lowest possible rate. It will be
assumed that the redemption is made first of amounts representing shares
acquired pursuant to the reinvestment of dividends and distributions; then of
amounts representing the increase in NAV above the total amount of payments
for the purchase of Portfolio shares made during the preceding four years;
then of amounts representing the cost of shares held beyond the applicable
CDSC period; and finally, of amounts representing the cost of shares held for
the longest period of time within the applicable CDSC period.
 
  For example, assume you purchased 100 Class B shares at $10 per share for a
cost of $1,000. Subsequently, you acquired 5 additional Class B shares through
dividend reinvestment. During the second year after the purchase you decided
to redeem $500 of your investment. Assuming at the time of the redemption the
net asset value had appreciated to $12 per share, the value of your Class B
shares would be $1,260 (105 shares at $12 per share). The CDSC would not be
applied to the value of the reinvested dividend shares and the amount which
represents appreciation ($260). Therefore, $240 of the $500 redemption
proceeds ($500 minus $260) would be charged at a rate of 2% (the applicable
rate in the second year after purchase) for a total CDSC of $4.80.
 
                                      25
<PAGE>
 
  For federal income tax purposes, the amount of the CDSC will reduce the gain
or increase the loss, as the case may be, on the amount recognized on the
redemption of shares.
 
  WAIVER OF THE CONTINGENT DEFERRED SALES CHARGES--CLASS B SHARES. The CDSC
will be waived in the case of a redemption following the death or disability
of a shareholder or, in the case of a trust account, following the death or
disability of the grantor. The waiver is available for total or partial
redemptions of shares owned by a person, either individually or in joint
tenancy (with rights of survivorship), at the time of death or initial
determination of disability, provided that the shares were purchased prior to
death or disability.
 
  The CDSC will also be waived in the case of a total or partial redemption in
connection with certain distributions made without penalty under the Internal
Revenue Code from a tax-deferred retirement plan, an IRA or Section 403(b)
custodial account. These distributions include: (i) in the case of a tax-
deferred retirement plan, a lump-sum or other distribution after retirement;
(ii) in the case of an IRA or Section 403(b) custodial account, a lump-sum or
other distribution after attaining age 59 1/2; and (iii) a tax-free return of
an excess contribution or plan distributions following the death or disability
of the shareholder, provided that the shares were purchase prior to death or
disability. The waiver does not apply in the case of a tax-free rollover or
transfer of assets, other than one following a separation from service (i.e.,
following voluntary or involuntary termination of employment or following
retirement). Under no circumstances will the CDSC be waived on redemptions
resulting from the termination of a tax-deferred retirement plan, unless such
redemptions otherwise qualify for a waiver as described above. In the case of
Direct Account and PSI or Subsidiary Prototype Benefit Plans, the CDSC will be
waived on redemptions which represent borrowings from such plans. Shares
purchased with amounts used to repay a loan from such plans on which a CDSC
was not previously deducted will thereafter be subject to a CDSC without
regard to the time such amounts were previously invested. In the case of a
401(k) plan, the CDSC will also be waived upon the redemption of shares
purchased with amounts used to repay loans made from the account to the
participant and from which a CDSC was previously deducted.
 
  In addition, the CDSC will be waived on redemptions of shares held by
Directors of the Fund.
 
  You must notify the Transfer Agent either directly or through Prudential
Securities or Prusec, at the time of redemption, that you are entitled to
waiver of the CDSC and provide the Transfer Agent with such supporting
documentation as it may deem appropriate. The waiver will be granted subject
to confirmation of your entitlement. See "Purchase and Redemption of Fund
Shares--Waiver of the Contingent Deferred Sales Charge--Class B Shares" in the
Statement of Additional Information.
 
  A quantity discount may apply to redemptions of Class B shares purchased
prior to August 1, 1994. See "Purchase and Redemption of Fund Shares--Quantity
Discount--Class B Shares Purchased Prior to August 1, 1994" in the Statement
of Additional Information.
 
CONVERSION FEATURE--CLASS B SHARES
 
  Class B shares will automatically convert to Class A shares on a quarterly
basis approximately five years after purchase. It is currently anticipated
that conversions will occur during the months of February, May, August and
November commencing in or about February 1995. Conversions will be effected at
relative net asset value without the imposition of any additional sales
charge.
 
  Since the Fund tracks amounts paid rather than the number of shares bought
on each purchase of Class B shares, the number of Class B shares eligible to
convert to Class A shares (excluding shares acquired through the automatic
reinvestment of dividends and other distributions) (the Eligible Shares) will
be determined on each conversion date in accordance with the following
formula: (i) the ratio of (a) the amounts paid for Class B shares purchased at
least five years prior to the conversion date to (b) the total amount paid for
all Class B shares purchased and then held in your account (ii) multiplied by
the total number of Class B shares purchased and then held in your account.
Each time any Eligible Shares in your account convert to Class A shares, all
shares or amounts representing Class B shares then in your account that were
acquired through the automatic reinvestment of dividends and other
distributions will convert to Class A shares.
 
                                      26
<PAGE>
 
  For purposes of determining the number of Eligible Shares, if the Class B
shares in your account on any conversion date are the result of multiple
purchases at different net asset values per share, the number of Eligible
Shares calculated as described above will generally be either more or less
than the number of shares actually purchased approximately five years before
such conversion date. For example, if 100 shares were initially purchased at
$10 per share (for a total of $1,000) and a second purchase of 100 shares was
subsequently made at $11 per share (for a total of $1,100), 95.24 shares would
convert approximately five years from the initial purchase (i.e., $1,000
divided by $2,100 (47.62%), multiplied by 200 shares equals 95.24 shares). The
Manager reserves the right to modify the formula for determining the number of
Eligible Shares in the future as it deems appropriate on notice to
shareholders.
 
  Since annual distribution-related fees are lower for Class A shares than
Class B shares, the per share net asset value of the Class A shares may be
higher than that of the Class B shares at the time of conversion. Thus,
although the aggregate dollar value will be the same, you may receive fewer
Class A shares than Class B shares converted. See "How the Fund Values its
Shares."
 
  For purposes of calculating the applicable holding period for conversions,
all payments for Class B shares during a month will be deemed to have been
made on the last day of the month, or for Class B shares acquired through
exchange, or a series of exchanges, on the last day of the month in which the
original payment for purchases of such Class B shares was made. For Class B
shares previously exchanged for shares of a money market fund, the time period
during which such shares were held in the money market fund will be excluded.
For example, Class B shares held in a money market fund for one year will not
convert to Class A shares until approximately six years from purchase. For
purposes of measuring the time period during which shares are held in a money
market fund, exchanges will be deemed to have been made on the last day of the
month. Class B shares acquired through exchange will convert to Class A shares
after expiration of the conversion period applicable to the original purchase
of such shares. The conversion feature described above will not be implemented
and, consequently, the first conversion of Class B shares will not occur
before February 1995, but as soon thereafter as practicable. At that time all
amounts representing Class B shares then outstanding beyond the applicable
conversion period will automatically convert to Class A shares together with
all shares or amounts representing Class B shares acquired through the
automatic reinvestment of dividends and distributions then held in your
account.
 
  The conversion feature may be subject to the continuing availability of
opinions of counsel or rulings of the Internal Revenue Service (i) that the
dividends and other distributions paid on Class A, Class B, and Class C shares
will not constitute "preferential dividends" under the Internal Revenue Code
and (ii) that the conversion of shares does not constitute a taxable event.
The conversion of Class B shares into Class A shares may be suspended if such
opinions or rulings are no longer available. If conversions are suspended,
Class B shares of the Portfolio will continue to be subject, possibly
indefinitely, to their higher annual distribution and service fee.
 
HOW TO EXCHANGE YOUR SHARES
 
  AS A SHAREHOLDER OF THE PORTFOLIO, YOU HAVE AN EXCHANGE PRIVILEGE WITH
CERTAIN OTHER PRUDENTIAL MUTUAL FUNDS (THE EXCHANGE PRIVILEGE), INCLUDING ONE
OR MORE SPECIFIED MONEY MARKET FUNDS, SUBJECT TO THE MINIMUM INVESTMENT
REQUIREMENTS OF SUCH FUNDS. CLASS A, CLASS B AND CLASS C SHARES MAY BE
EXCHANGED FOR CLASS A, CLASS B AND CLASS C SHARES, RESPECTIVELY, OF ANOTHER
FUND ON THE BASIS OF THE RELATIVE NAV. No sales charge will be imposed at the
time of the exchange. Any applicable CDSC payable upon the redemption of
shares exchanged will be calculated from the first day of the month after the
date of the initial purchase, excluding the time shares were held in a money
market fund. Class B and Class C shares may not be exchanged into money market
funds other than Prudential Special Money Market Fund. For purposes of
calculating the holding period applicable to the Class B conversion feature,
the time period during which Class B shares were held in a money market fund
will be excluded. See "Conversion Feature--Class B Shares" above. An exchange
will be treated as a redemption and purchase for tax purposes. See
"Shareholder Investment Account--Exchange Privilege" in the Statement of
Additional Information.

weekdays, except holidays, between the hours of 8:00 A.M. and 6:00 P.M., New
York time. For your protection and to prevent fraudulent exchanges, your
telephone call will be recorded and you will be asked to provide your personal
identification number. A written confirmation of the exchange transaction will
be sent to you. NEITHER THE FUND NOR ITS AGENTS WILL BE LIABLE FOR ANY LOSS,
LIABILITY OR COST WHICH RESULTS FROM ACTING UPON INSTRUCTIONS REASONABLY
BELIEVED TO BE GENUINE UNDER THE FOREGOING PROCEDURES. All exchanges will be
made on the basis of the relative NAV of the two funds next determined after
the request is received in good order. The Exchange Privilege is available
only in states where the exchange may legally be made.
 
  IF YOU HOLD SHARES THROUGH PRUDENTIAL SECURITIES, YOU MUST EXCHANGE YOUR
SHARES BY CONTACTING YOUR PRUDENTIAL SECURITIES FINANCIAL ADVISER.
 
  IF YOU HOLD CERTIFICATES, THE CERTIFICATES, SIGNED IN THE NAME(S) SHOWN ON
THE FACE OF THE CERTIFICATES MUST BE RETURNED IN ORDER FOR THE SHARES TO BE
EXCHANGED. SEE "HOW TO SELL YOUR SHARES" ABOVE.
 
  You may also exchange shares by mail by writing to Prudential Mutual Fund
Services, Inc., Attention: Exchange Processing, P.O. Box 15010, New Brunswick,
New Jersey 08906-5010.
 
  IN PERIODS OF SEVERE MARKET OR ECONOMIC CONDITIONS THE TELEPHONE EXCHANGE OF
SHARES MAY BE DIFFICULT TO IMPLEMENT AND YOU SHOULD MAKE EXCHANGES BY MAIL BY
WRITING TO PRUDENTIAL MUTUAL FUND SERVICES, INC., AT THE ADDRESS NOTED ABOVE.
 
  SPECIAL EXCHANGE PRIVILEGE. Commencing in or about February 1995, a special
exchange privilege is available for shareholders who qualify to purchase Class
A shares at NAV. See "Alternative Purchase Plan--Class A Shares--Reduction and
Waiver of Initial Sales Charges" above. Under this exchange privilege, amounts
representing any Class B and Class C shares (which are not subject to a CDSC)
held in such a shareholder's account will be automatically exchanged for Class
A shares on a quarterly basis, unless the shareholder elects otherwise. It is
currently anticipated that this exchange will occur quarterly in February,
May, August and November. Eligibility for this exchange privilege will be
calculated on the business day prior to the date of the exchange. Amounts
representing Class B or Class C shares which are not subject to a CDSC include
the following: (1) amounts representing Class B or Class C shares acquired
pursuant to the automatic reinvestment of dividends and distributions, (2)
amounts representing the increase in the net asset value above the total
amount of payments for the purchase of Class B or Class C shares and (3)
amounts representing Class B or Class C shares held beyond the applicable CDSC
period. Class B and Class C shareholders must notify the Transfer Agent either
directly or through Prudential Securities or Prusec that they are eligible for
this special exchange privilege.
 
  The Exchange Privilege may be modified or terminated at any time on 60 days'
notice to shareholders.
 
SHAREHOLDER SERVICES
 
  In addition to the Exchange Privilege, as a shareholder in the Portfolio you
can take advantage of the following additional services and privileges.
 
  . AUTOMATIC REINVESTMENT OF DIVIDENDS AND/OR DISTRIBUTIONS WITHOUT A SALES
CHARGE. For your convenience, all dividends and distributions are
automatically reinvested in full and fractional shares of the Portfolio at NAV
without a sales charge. You may direct the Transfer Agent in writing not less
than 5 full business days prior to the record date to have subsequent
dividends and/or distributions sent in cash rather than reinvested. If you
hold shares through Prudential Securities, you should contact your financial
adviser.
 
  . AUTOMATIC SAVINGS ACCUMULATION PLAN (ASAP) Under ASAP, you may make
regular purchases of the Portfolio's shares in amounts as little as $50 via an
automatic debit to a bank account or Prudential Securities account (including
a Command Account). For additional information about this service, you may
contact your Prudential Securities financial adviser, Prusec representative or
the Transfer Agent directly.
 
                                      28
<PAGE>
 
  . TAX DEFERRED RETIREMENT PLANS. Various tax-deferred retirement plans,
including a 401(k) plan, self-directed individual retirement accounts and
"tax-sheltered accounts" under Section 403(b)(7) of the Internal Revenue Code
are available through the Distributor. These plans are for use by both self-
employed individuals and corporate employers. These plans permit either self-
direction of accounts by participants, or a pooled account arrangement.
Information regarding the establishment of these plans, the administration,
custodial fees and other details is available from Prudential Securities or
the Transfer Agent. If you are considering adopting such a plan, you should
consult with your own legal or tax adviser with respect to the establishment
and maintenance of such a plan.
 
  . SYSTEMATIC WITHDRAWAL PLAN. A systematic withdrawal plan is available to
shareholders which provides for monthly or quarterly checks. Withdrawals of
Class B and Class C shares may be subject to a CDSC. See "How to Sell Your
Shares--Contingent Deferred Sales Charges" above.
 
  . REPORTS TO SHAREHOLDERS. The Fund will send you annual and semi-annual
reports. The financial statements appearing in annual reports are audited by
independent accountants. In order to reduce duplicate mailing and printing
expenses, the Fund will provide one annual and semi-annual shareholder report
and annual prospectus per household. You may request additional copies of such
reports by calling (800) 225-1852 or by writing to the Fund at One Seaport
Plaza, New York, New York 10292. In addition, monthly unaudited financial data
are available upon request from the Fund.
 
  . SHAREHOLDER INQUIRIES. Inquiries should be addressed to the Fund at One
Seaport Plaza, New York, New York 10292, or by telephone, at (800) 225-1852

                        DESCRIPTION OF SECURITY RATINGS
 
MOODY'S INVESTORS SERVICE
 
BOND RATINGS
 
  Aaa: Bonds which are rated Aaa are judged to be of the best quality. They
carry the smallest degree of investment risk and are generally referred to as
"gilt edged." Interest payments are protected by a large or by an
exceptionally stable margin and principal is secure. While the various
protective elements are likely to change, such changes as can be visualized
are most unlikely to impair the fundamentally strong position of such issues.
 
  Aa: Bonds which are rated Aa are judged to be of high quality by all
standards. Together with the Aaa group they comprise what are generally known
as high grade bonds. They are rated lower than Aaa bonds because margins of
protection may not be as large as in Aaa securities or fluctuation of
protective elements may be of greater amplitude or there may be other elements
present which make the long-term risks appear somewhat larger than in Aaa
securities.
 
  A: Bonds which are rated A possess many favorable investment attributes and
are to be considered as upper medium grade obligations. Factors giving
security to principal and interest are considered adequate but elements may be
present which suggest a susceptibility to impairment some time in the future.
 
  Baa: Bonds which are rated Baa are considered as medium grade obligations
(i.e., they are neither highly protected nor poorly secured.) Interest
payments and principal security appear adequate for the present, but certain
protective elements may be lacking or may be characteristically unreliable
over any great length of time. Such bonds lack outstanding investment
characteristics and in fact have speculative characteristics as well.
 
  Ba: Bonds which are rated Ba are judged to have speculative elements; their
future cannot be considered as well assured. Often the protection of interest
and principal payments may be very moderate and thereby not well safeguarded
during both good and bad times over the future. Uncertainty of position
characterizes bonds in this class.
 
  B: Bonds which are rated B generally lack characteristics of the desirable
investment. Assurance of interest and principal payments or of maintenance of
other terms of the contract over any long period of time may be small.
 
  Moody's applies numerical modifiers 1, 2 and 3 in each generic rating
classification from Aa to B. The modifier 1 indicates that the company ranks
in the higher end of its generic rating category; the modifier 2 indicates a
mid-range ranking; and the modifier 3 indicates that the company ranks in the
lower end of its generic rating category.
 
  Caa: Bonds which are rated Caa are of poor standing. Such issues may be in
default or there may be present elements of danger with respect to principal
or interest.
 
  Ca: Bonds which are rated Ca represent obligations which are speculative in
a high degree. Such issues are often in default or have other marked
shortcomings.
 
  C: Bonds which are rated C are the lowest rated class of bonds, and issues
so rated can be regarded as having extremely poor prospects of ever attaining
any real investment standing.
 
SHORT-TERM DEBT RATINGS
 
  Moody's short-term debt ratings are opinions of the ability of issuers to
repay punctually senior debt obligations which have an original maturity not
exceeding one year.
 
  P-1: Issuers rated Prime-1 or P-1 (or supporting institutions) have a
superior ability for repayment of senior short-term debt obligations.
 
  P-2: Issuers rated Prime-2 or P-2 (or supporting institutions) have a strong
ability for repayment of senior short-term debt obligations.
 
STANDARD & POOR'S RATINGS GROUP
 
DEBT RATINGS
 
  AAA: Debt rated AAA has the highest rating assigned by Standard & Poor's.
Capacity to pay interest and repay principal is extremely strong.
 
                                      A-1
<PAGE>
 
  AA: Debt rated AA has a very strong capacity to pay interest and repay
principal and differs from the highest-rated issues only in small degree.
 
  A: Debt rated A has a strong capacity to pay interest and repay principal
although it is somewhat more susceptible to the adverse effects of changes in
circumstances and economic conditions than debt in higher-rated categories.
 
  BBB: Debt rated BBB is regarded as having an adequate capacity to pay
interest and repay principal. Whereas it normally exhibits adequate protection
parameters, adverse economic conditions or changing circumstances are more
likely to lead to a weakened capacity to pay interest and repay principal for
debt in this category than for debt in higher-rated categories.
 
  BB, B, CCC, CC AND C: Debt rated BB, B, CCC, CC and C is regarded, on
balance, as having predominantly speculative characteristics with respect to
capacity to pay interest and repay principal. BB indicates the least degree of
speculation and C the highest degree of speculation. While such debt will
likely have some quality and protective characteristics, these are outweighed
by large uncertainties or major risk exposures to adverse conditions.
 
COMMERCIAL PAPER RATINGS
 
  Standard & Poor's commercial paper ratings are current assessments of the
likelihood of timely payment of debt considered short-term in the relevant
market.
 
  A-1: The A-1 designation indicates that the degree of safety regarding
timely payment is strong. Those issues determined to possess extremely strong
safety characteristics are denoted with a plus sign (+) designation.
 
  A-2: Capacity for timely payment on issues with the designation A-2 is
satisfactory. However, the relative degree of safety is not as high as for
issues designated A-1.

                      Statement of Additional Information
                             dated August 1, 1994
 
  Prudential Structured Maturity Fund, Inc. (the Fund), is an open-end,
management investment company comprised of two Portfolios--the Income
Portfolio and the Municipal Income Portfolio. Only the Income Portfolio is
offered at this time. The investment objective of the Income Portfolio (the
Portfolio) is high current income consistent with the preservation of
principal. The Portfolio seeks to achieve its objective primarily through
structuring its portfolio by utilizing a "laddered" maturity strategy. The
Portfolio invests primarily in investment grade corporate debt securities and
in obligations of the U.S. Government, its agencies and instrumentalities with
maturities of six years or less. The Portfolio may also invest up to 10% of
its total assets in securities rated below BBB by Standard & Poor's Ratings
Group or Baa by Moody's Investor Service (or a similar nationally recognized
rating service), or, if not rated, of comparable quality in the opinion of the
investment adviser. These securities are allocated by maturity among six
annual maturity categories ranging from one year or less to between five and
six years with each category representing approximately one-sixth of the
Portfolio's assets. As the securities in each annual category mature or as new
investments are made in the Portfolio, the proceeds will be invested to
maintain the balance of investments among the six annual maturity categories.
There can be no assurance that the Portfolio's investment objective will be
achieved. See "Investment Objective and Policies."
 
  The Fund's address is One Seaport Plaza, New York, New York 10292, and its
telephone number is (800) 225-1852.
 
  This Statement of Additional Information is not a prospectus and should be
read in conjunction with the Prospectus of the Income Portfolio, dated August
1, 1994, a copy of which may be obtained from the Fund upon request.

                              GENERAL INFORMATION
 
  At a special meeting held on July 19, 1994, shareholders approved an
amendment to the Fund's Articles of Incorporation to change the Fund's name
from Prudential-Bache Structured Maturity Fund, Inc. to Prudential Structured
Maturity Fund, Inc.
 
  The Fund initially offered only one series known as Prudential Structured
Maturity Fund. On July 15, 1993, the Board of Directors authorized the
creation of the Municipal Income Portfolio and approved the designation of the
existing shares of the Fund as shares of the Income Portfolio.
 
                       INVESTMENT OBJECTIVE AND POLICIES
 
  The investment objective of the Income Portfolio (the Portfolio) is high
current income consistent with the preservation of principal. See "How the
Fund Invests--Investment Objective and Policies" in the Prospectus. The
Portfolio seeks to achieve its objective primarily through structuring its
portfolio by utilizing a "laddered" maturity strategy. The Portfolio invests
primarily in investment grade corporate debt securities and in obligations of
the U.S. Government, its agencies and instrumentalities with maturities of six
years or less. The Portfolio may also invest up to 10% of its total assets in
securities rated below BBB by Standard & Poor's Ratings Group (S&P) or Baa by
Moody's Investor Service (Moody's) (or a similar nationally recognized rating
service), or, if not rated, of comparable quality in the opinion of the
investment adviser. Under normal market conditions these securities are
allocated by maturity among six annual maturity categories ranging from one
year or less to between five and six years with each category representing
approximately one-sixth of the Portfolio's assets. As the securities in each
annual category mature or as new investments are made in the Portfolio, the
proceeds will be invested to maintain the balance of investments among the six
annual maturity categories. There can be no assurance that the Portfolio's
investment objective will be achieved.
 
  The Portfolio may invest in the following types of securities:
 
U.S. Government Securities
 
  MORTGAGE-RELATED SECURITIES ISSUED BY U.S. GOVERNMENT INSTRUMENTALITIES.
Mortgages backing the securities purchased by the Portfolio include
conventional thirty-year fixed-rate mortgages, graduated payment mortgages,
fifteen-year mortgages, adjustable rate mortgages and balloon payment
mortgages. A balloon payment mortgage-backed security is an amortizing
mortgage security with installments of principal and interest, the last
installment of which is predominantly principal. All of these mortgages can be
used to create pass-through securities. A pass-through security is formed when
mortgages are pooled together and undivided interests in the pool or pools are
sold. The cash flow from the mortgages is passed through to the holders of the
securities in the form of periodic payments of interest, principal and
prepayments (net of a service fee). Prepayments occur when the holder of an
undivided mortgage prepays the remaining principal before the mortgage's
scheduled maturity date. As a result of the pass-through of prepayments of
principal on the underlying securities, mortgage-backed securities are often
subject to more rapid prepayment of principal than their stated maturity would
indicate. The remaining expected average life of a pool of mortgage loans
underlying a mortgage-backed security is a prediction of when the mortgage
loans will be repaid and is based upon a variety of factors, such as the
demographic and geographic characteristics of the borrowers and the mortgaged
properties, the length of time that each of the mortgage loans has been
outstanding, the interest rates payable on the mortgage loans and the current
interest rate environment. Because mortgage-backed securities are often
prepaid, a pass-through security with a stated remaining maturity of more than
its remaining expected average life will be deemed by the Portfolio, for
purposes of determining the Portfolio's effective dollar-weighted average
maturity, to have a remaining maturity equal to its remaining expected average
life. The determination of the remaining expected average life of mortgage-
backed securities will be made by the investment adviser, subject to the
supervision of the Fund's Board of Directors. In selecting investments for the
Portfolio and in determining the remaining maturity, the investment adviser
will rely on average remaining life data published by various mortgage-backed
securities dealers except to the extent such data are deemed unreasonable by
the investment adviser. The investment adviser might deem such data
unreasonable if such data appeared to present a significantly different
average remaining expected life for a security when compared to data relating
to the average remaining life of comparable securities as provided by other
independent mortgage-backed securities dealers. The Portfolio's effective
dollar-weighted average maturity is expected to be between 2 1/2 and 3 1/2
years.
 
  During periods of declining interest rates, prepayment of mortgages
underlying mortgage-backed securities can be expected to accelerate. When
mortgage obligations are prepaid, the Portfolio reinvests the prepaid amounts
in securities, the yields of which reflect interest rates prevailing at that
time. Therefore, the Portfolio's ability to maintain a portfolio of high-
yielding mortgage-backed securities will be adversely affected to the extent
that prepayments of mortgages must be reinvested in securities which have
lower yields than the prepaid mortgages. Moreover, prepayments of mortgages
which underlie securities purchased at a premium generally will result in
capital losses.
 
  GNMA CERTIFICATES. Certificates of the Government National Mortgage
Association (GNMA Certificates) are mortgage-backed securities which evidence
an undivided interest in a pool of mortgage loans. GNMA Certificates differ
from bonds in that principal is
 
                                      B-2
<PAGE>
 
paid back monthly by the borrower over the term of the loan rather than
returned in a lump sum at maturity. GNMA Certificates that the Portfolio
purchases are the "modified pass-through" type. "Modified pass-through" GNMA
Certificates entitle the holder to receive a share of all interest and
principal prepayments paid and owed on the mortgage pool, net of fees paid to
the "issuer" and GNMA, regardless of whether or not the mortgagor actually
makes the payment. The GNMA Certificates will represent a pro rata interest in
one or more pools of the following types of mortgage loans: (i) fixed-rate
level payment mortgage loans; (ii) fixed-rate graduated payment mortgage
loans; (iii) fixed-rate growing equity mortgage loans; (iv) fixed-rate
mortgage loans secured by manufactured (mobile) homes; (v) mortgage loans on
multi-family residential properties under construction; (vi) mortgage loans on
completed multi-family projects; (vii) fixed-rate mortgage loans as to which
escrowed funds are used to reduce the borrower's monthly payments during the
early years of the mortgage loans ("buydown" mortgage loans); (viii) mortgage
loans that provide for adjustments in payments based on periodic changes in
interest rates or in other payment terms of the mortgage loans; and (ix)
mortgage-backed serial notes. All of these mortgage loans will be FHA Loans or
VA Loans and, except as otherwise specified above, will be fully-amortizing
loans secured by first liens on one-to-four family housing units.
 
  GNMA GUARANTEE. GNMA is a wholly-owned corporate instrumentality of the
United States within the Department of Housing and Urban Development. The
National Housing Act, as amended (the Housing Act), authorizes GNMA to
guarantee the timely payment of principal and interest on certificates that
are based on and backed by a pool of mortgages insured by the Federal Housing
Administration under the Housing Act, or Title V of the Housing Act of 1949
(FHA loans), or guaranteed by the Veterans Administration under the
Servicemen's Retirement Act of 1944, as amended (VA loans), or by pools of
other eligible mortgage loans. The Housing Act provides that the full faith
and credit of the U.S. Government is pledged to the payment of all amounts
that may be required to be paid under the guarantee. In order to meet its
obligations under such guarantee, GNMA is authorized to borrow from the U.S.
Treasury with no limitations as to amount.
 
  FHLMC SECURITIES. The Federal Home Loan Mortgage Corporation was created in
1970 through enactment of Title III of the Emergency Home Finance Act of 1970.
Its purpose is to promote development of a nationwide secondary market in
conventional residential mortgages.
 
  The FHLMC presently issues two types of mortgage pass-through securities,
mortgage participation certificates (PCs) and guaranteed mortgage
certificates. The Portfolio does not intend to invest in guaranteed mortgage
certificates. PCs resemble GNMA Certificates in that each PC represents a pro
rata share of all interest and principal payments made and owed on the
underlying pool. The FHLMC guarantees timely monthly payment of interest on
PCs and the stated principal amount.
 
  FNMA SECURITIES. The Federal National Mortgage Association was established
in 1938 to create a secondary market in mortgages. FNMA issues guaranteed
mortgage pass-through certificates (FNMA Certificates). FNMA Certificates
resemble GNMA Certificates in that each FNMA Certificate represents a pro rata
share of all interest and principal payments made and owed on the underlying
pool. FNMA guarantees timely payment of interest on FNMA Certificates and the
stated principal amount.
 
  ADJUSTABLE RATE MORTGAGE SECURITIES. Generally, adjustable rate mortgage
securities (ARMs) have a specified maturity date and amortize principal over
their life. In periods of declining interest rates, there is a reasonable
likelihood that ARMs will experience increased rates of prepayment of
principal. However, the major difference between ARMs and fixed-rate mortgage
securities (FRMs) is that the interest rate and the rate of amortization of
principal of ARMs can and do change in accordance with movements in a
particular, pre-specified, published interest rate index. The amount of
interest on an ARM is calculated by adding a specified amount, the "margin,"
to the index, subject to limitations on the maximum and minimum interest that
is charged during the life of the mortgage or to maximum and minimum changes
to that interest rate during a given period. Because the interest rate on ARMs
generally moves in the same direction as market interest rates, the market
value of ARMs tends to be more stable than that of long-term fixed-rate
securities. The Portfolio expects this characteristic to contribute to its
objective of preservation of principal.
 
  FIXED-RATE MORTGAGE SECURITIES. The Portfolio anticipates investing in high-
coupon fixed-rate mortgage securities. Such securities are collateralized by
fixed-rate mortgages and tend to have high prepayment rates when the level of
prevailing interest rates declines significantly below the interest rates on
the mortgages. Thus, under those circumstances, the securities are generally
less sensitive to interest rate movements than lower coupon FRMs.
 
  CHARACTERISTICS OF MORTGAGE-BACKED SECURITIES. The interest rates paid on
the ARMs in which the Portfolio invests generally are readjusted at intervals
of one year or less to an increment over some predetermined interest rate
index. There are two main categories of indices: those based on U.S. Treasury
securities and those derived from a calculated measure such as a cost of funds
index or a moving average of mortgage rates. Commonly utilized indices include
the one-year and five-year constant maturity Treasury Note rates, the three-
month Treasury Bill rate, the 180-day Treasury Bill rate, rates on longer-term
Treasury securities, the 11th District Federal Home Loan Bank Cost of Funds,
the National Median Cost of Funds, the one-month or three-month London
Interbank Offered Rate (LIBOR), the prime rate of a specific bank, or
commercial paper rates. Some indices, such as the one-year constant maturity
Treasury Note rate, closely mirror changes in market interest rate levels.
Others, such as the 11th District Home Loan Bank Cost of Funds index (often
related to ARMs issued by FNMA), tend to lag behind changes in market rate
levels and tend to be somewhat less volatile.
 
                                      B-3
<PAGE>
 
  The underlying mortgages which collateralize the ARMs, collateralized
mortgage obligations (CMOs) and real estate mortgage investment conduits
(REMICs), in which the Portfolio invests will frequently have caps and floors
which limit the maximum amount by which the loan rate to the residential
borrower may change up or down (1) per reset or adjustment interval and (2)
over the life of the loan. Some residential mortgage loans restrict periodic
adjustments by limiting changes in the borrower's monthly principal and
interest payments rather than limiting interest rate changes. These payment
caps may result in negative amortization.
 
  The market value of mortgage securities, like other U.S. Government
securities, will generally vary inversely with changes in market interest
rates, declining when interest rates rise and rising when interest rates
decline. However, mortgage securities, while having comparable risk of decline
during periods of rising rates, usually have less potential for capital
appreciation than other investments of comparable maturities due to the
likelihood of increased prepayments of mortgages as interest rates decline. In
addition, to the extent such mortgage securities are purchased at a premium,
mortgage foreclosures and unscheduled principal prepayments generally will
result in some loss of the holders' principal to the extent of the premium
paid. On the other hand, if such mortgage securities are purchased at a
discount, an unscheduled prepayment of principal will increase current and
total returns and will accelerate the recognition of income which when
distributed to shareholders will be taxable as ordinary income.
 
  In addition, mortgage-backed securities which are secured by manufactured
(mobile) homes and multi-family residential properties, such as GNMA and FNMA
certificates, are subject to a higher risk of default than are other types of
mortgage-backed securities. The investment adviser will seek to minimize this
risk by investing in mortgage-backed securities rated at least A by Moody's or
S&P.
 
  STRIPS. The Portfolio may invest in component parts of U.S. Government
securities, namely, either the corpus (principal) of such obligations or one
of the interest payments scheduled to be paid on such obligations. These
obligations may take the form of (i) obligations from which the interest
coupons have been stripped, (ii) the interest coupons that are stripped, (iii)
book entries at a Federal Reserve member bank representing ownership of
obligation components or (iv) receipts evidencing the component parts (corpus
or coupons) of U.S. Government obligations that have not actually been
stripped. Such receipts evidence ownership of component parts of U.S.
Government obligations (corpus or coupons) purchased by a third party
(typically an investment banking firm) and held on behalf of the third party
in physical or book-entry form by a major commercial bank or trust company
pursuant to a custody agreement with the third party. U.S. Government
obligations, including those underlying such receipts, are backed by the full
faith and credit of the U.S. Government.
 
Mortgage-Backed Securities
 
  Mortgage-backed securities are securities that directly or indirectly
represent a participation in, or are secured by and payable from, mortgage
loans secured by real property. There are currently three basic types of
mortgage-backed securities: (i) those issued or guaranteed by the U.S.
Government or one of its agencies or instrumentalities, such as GNMA, FNMA and
FHLMC, described under "U.S. Government Securities" above; (ii) those issued
by private issuers that represent an interest in or are collateralized by
mortgage-backed securities issued or guaranteed by the U.S. Government or one
of its agencies or instrumentalities; and (iii) those issued by private
issuers that represent an interest in or are collateralized by whole mortgage
loans or mortgage-backed securities without a U.S. Government guarantee but
usually having some form of private credit enhancement.
 
  The Portfolio intends to invest in non-agency whole loan mortgage-backed
securities rated at least AA by S&P or Aa by Moody's.
 
  Private mortgage pass-through securities are structured similarly to the
GNMA, FNMA and FHLMC mortgage pass-through securities and are issued by
originators of and investors in mortgage loans, including depository
institutions, mortgage banks, investment banks and special purpose
subsidiaries of the foregoing. These securities usually are backed by a pool
of conventional fixed-rate or adjustable rate mortgage loans. Since private
mortgage pass-through securities typically are not guaranteed by an entity
having the credit status of GNMA, FNMA and FHLMC, such securities generally
are structured with one or more types of credit enhancement.
 
  COLLATERALIZED MORTGAGE OBLIGATIONS. Certain issuers of mortgage-backed
obligations (CMOs), including certain CMOs that have elected to be treated as
Real Estate Mortgage Investment Conduits (REMICs), are not considered
investment companies pursuant to a rule adopted by the Securities and Exchange
Commission (SEC), and the Portfolio may invest in the securities of such
issuers without the limitations imposed by the Investment Company Act of 1940
(the Investment Company Act) on investments by the Portfolio in other
investment companies. In addition, in reliance on an earlier SEC
interpretation, the Portfolio's investments in certain other qualifying CMOs,
which cannot or do not rely on the rule, are also not subject to the
limitation of the Investment Company Act on acquiring interests in other
investment companies. In order to be able to rely on the SEC's interpretation,
these CMOs must be unmanaged, fixed asset issuers, that (a) invest primarily
in mortgage-backed securities, (b) do not issue redeemable securities, (c)
operate under general exemptive orders exempting them from all provisions of
the Investment Company Act, and (d) are not registered or regulated under the
Investment Company Act as investment companies. To the extent that the
Portfolio selects CMOs or REMICs that cannot rely on the rule or do not meet
the above requirements, the Portfolio may not invest more than 10% of its
assets in all such entities and may not acquire more than 3% of the voting
securities of any single such entity.
 
                                      B-4

OTHER INVESTMENTS
 
  REPURCHASE AGREEMENTS. The Portfolio may enter into repurchase agreement
transactions. The Portfolio's repurchase agreements will be collateralized by
U.S. Government obligations. The Portfolio will enter into repurchase
transactions only with parties meeting creditworthiness standards approved by
the Fund's Board of Directors. The Fund's investment adviser will monitor the
creditworthiness of such parties, under the general supervision of the Board
of Directors. In the event of a default or bankruptcy by a seller, the
Portfolio will promptly seek to liquidate the collateral. To the extent that
the proceeds from any sale of such collateral upon a default in the obligation
to repurchase are less than the repurchase price, the Portfolio will suffer a
loss.
 
  The Fund participates in a joint repurchase account with other investment
companies managed by Prudential Mutual Fund Management, Inc. (PMF) pursuant to
an order of the SEC. On a daily basis, any uninvested cash balances of the
Portfolio may be aggregated with those of such investment companies and
invested in one or more repurchase agreements. Each fund participates in the
income earned or accrued in the joint account based on the percentage of its
investment.
 
  MONEY MARKET INSTRUMENTS. The Portfolio may invest in high quality money
market instruments, including:
 
  1. Obligations denominated in U.S. dollars (including certificates of
deposit, bankers' acceptances and time deposits) of commercial banks, savings
banks and savings and loan associations having, at the time of acquisition by
the Portfolio of such obligations, total assets of not less than $1 billion or
its equivalent. The Portfolio may invest in obligations of domestic banks,
foreign banks, and branches and offices thereof. The term "certificates of
deposit" includes both Eurodollar certificates of deposit, for which there is
generally a market, and Eurodollar time deposits, for which there is generally
not a market. "Eurodollars" are U.S. dollars deposited in banks outside the
United States. For this purpose, the certificates of deposit may have terms in
excess of one year.
 
  2. Commercial paper, variable amount demand master notes, bills, notes and
other obligations issued by a U.S. company, a foreign company or a foreign
government, its agencies, instrumentalities or political subdivisions,
maturing in one year or less, denominated in U.S. dollars, and, at the date of
investment, rated at least A-2 by S&P or Prime-2 by Moody's, or, if not rated,
issued by an entity having an outstanding unsecured debt issue rated at least
A or A-2 by S&P or A or Prime-2 by Moody's. If such obligations are guaranteed
or supported by a letter of credit issued by a bank, the bank (including a
foreign bank) must meet the requirements set forth in paragraph 1 above. If
such obligations are guaranteed or insured by an insurance company or other
non-bank entity, the insurance company or other non-bank entity must represent
a credit of high quality, as determined by the Fund's Board of Directors.
Under the Investment Company Act, a guaranty is not deemed to be a security of
the guarantor for purposes of satisfying the diversification requirements
provided that the securities issued or guaranteed by the guarantor and held by
the Portfolio do not exceed 10% of the Portfolio's total assets.
 
  LENDING OF SECURITIES. Consistent with applicable regulatory requirements,
the Portfolio may lend its portfolio securities to brokers, dealers and
financial institutions, provided that outstanding loans do not exceed in the
aggregate 30% of the value of the Portfolio's total assets and that such loans
are callable at any time by the Portfolio and are at all times secured by cash
or equivalent collateral that is equal to at least the market value,
determined daily, of the loaned securities. The advantage of such loans is
that the Portfolio continues to receive payments in lieu of the interest and
dividends of the loaned securities, while at the same time earning interest
either directly from the borrower or on the collateral which will be invested
in short-term obligations.
 
  A loan may be terminated by the borrower on one business day's notice or by
the Portfolio at any time. If the borrower fails to maintain the requisite
amount of collateral, the loan automatically terminates, and the Portfolio
could use the collateral to replace the securities while holding the borrower
liable for any excess of replacement cost over collateral. As with any
extensions of credit, there are risks of delay in recovery and in some cases
loss of rights in the collateral should the borrower of the securities fail
financially. However, these loans of portfolio securities will be made only to
firms determined to be creditworthy pursuant to procedures approved by the
Board of Directors of the Fund. On termination of the loan, the borrower is
required to return the securities to the Portfolio, and any gain or loss in
the market price during the loan would inure to the Portfolio.
 
  Since voting or consent rights, if any, which accompany loaned securities
pass to the borrower, the Portfolio will follow the policy of calling the
loan, in whole or in part as may be appropriate, to permit the exercise of
such rights if the matters involved would have a material effect on the
Portfolio's investment in the securities which are the subject of the loan.
The Portfolio will pay reasonable finders', administrative and custodial fees
in connection with a loan of its securities or may share the interest earned
on collateral with the borrower.
 
  RISK FACTORS RELATING TO INVESTING IN HIGH YIELD SECURITIES. Fixed-income
securities are subject to the risk of an issuer's inability to meet principal
and interest payments on the obligations (credit risk) and may also be subject
to price volatility due to such factors as interest rate sensitivity, market
perception of the creditworthiness of the issuer and general market liquidity
(market risk). Lower rated or unrated (i.e., high yield) securities, commonly
referred to as "junk bonds," are more likely to react to developments
affecting market and credit risk than are more highly rated securities, which
react primarily to movements in the general level of interest
 
                                      B-5
<PAGE>
 
rates. The investment adviser considers both credit risk and market risk in
making investment decisions for the Portfolio. Investors should carefully
consider the relative risks of investing in high yield securities and
understand that such securities are not generally meant for short-term
investing.
 
  Federal laws require the divestiture by federally insured savings and loan
associations of their investments in high yield bonds and limit the
deductibility of interest by certain corporate issuers of high yield bonds.
These laws could also adversely affect the Portfolio's net asset value and
investment practices, the secondary market for high yield securities, the
financial condition of issuers of these securities and the value of
outstanding high yield securities.
 
  Lower rated or unrated debt obligations also present risks based on payment
expectations. If an issuer calls the obligation for redemption, the Portfolio
may have to replace the security with a lower yielding security, resulting in
a decreased return for investors. If the Portfolio experiences unexpected net
redemptions, it may be forced to sell its higher quality securities, resulting
in a decline in the overall credit quality of the Portfolio and increasing the
exposure of the Portfolio to the risks of high yield securities.
 
  WORLD BANK OBLIGATIONS. The Portfolio may purchase obligations of the
International Bank for Reconstruction and Development (the World Bank).
Obligations of the World Bank are supported by appropriated but unpaid
commitments of its member countries, including the U.S., and there is no
assurance these commitments will be undertaken or met in the future.
 
  INSTRUMENTS WITH PUTS. The Portfolio may purchase money market instruments
together with the right to resell the instruments at an agreed-upon price or
yield within a specified period prior to the maturity date of the instruments.
Such a right to resell is commonly known as a "put," and the aggregate price
which the Portfolio pays for instruments with puts may be higher than the
price which otherwise would be paid for the instruments. Consistent with the
Portfolio's investment objective and applicable rules issued by the SEC and
subject to the supervision of the Board of Directors, the purpose of this
practice is to permit the Portfolio to be fully invested while preserving the
necessary liquidity to meet unusually large redemptions and to purchase at a
later date securities other than those subject to the put. Puts may be
exercised prior to the expiration date in order to fund obligations to
purchase other securities or to meet redemption requests. These obligations
may arise during periods in which proceeds from sales of portfolio shares and
from recent sales of portfolio securities are insufficient to meet such
obligations or when the funds available are otherwise allocated for
investment. In addition, puts may be exercised prior to the expiration date in
the event the investment adviser revises its evaluation of the
creditworthiness of the issuer of the underlying security. In determining
whether to exercise puts prior to their expiration date and in selecting which
puts to exercise in such circumstances, the investment adviser considers,
among other things, the amount of cash available to the Portfolio, the
expiration dates of the available puts, any future commitments for securities
purchases, the yield, quality and maturity dates of the underlying securities,
alternative investment opportunities and the desirability of retaining the
underlying securities in the Portfolio. When the put is at the option of the
Portfolio, the Portfolio considers the maturity of an instrument subject to
the put to be the earlier of the put expiration date or the stated maturity of
the instrument.
 
  Since the value of the put is dependent on the ability of the put writer to
meet its obligation to repurchase, the Portfolio's policy is to enter into put
transactions only with such brokers, dealers or financial institutions which
present minimal credit risks. There is a credit risk associated with the
purchase of puts in that the broker, dealer or financial institution might
default on its obligation to repurchase an underlying security. In the event
such a default should occur, the Portfolio is unable to predict whether all or
any portion of any loss sustained could subsequently be recovered from the
broker, dealer or financial institution.
 
  OPTIONS TRANSACTIONS. The Portfolio reserves the right to enter into options
transactions but has no intention of doing so in the foreseeable future and
until supplemental disclosure is provided in the Prospectus and Statement of
Additional Information.
 
  INTEREST RATE SWAP TRANSACTIONS. The Portfolio may enter into interest rate
swap transactions, on either an asset-based or liability-based basis,
depending on whether it is hedging its assets or its liabilities. Under normal
circumstances, the Portfolio will enter into interest rate swaps on a net
basis, i.e., the two payment streams are netted out, with the Portfolio
receiving or paying, as the case may be, only the net amount of the two
payments. The net amount of the excess, if any, of the Portfolio's obligations
over its entitlements with respect to each interest rate swap will be accrued
on a daily basis and an amount of cash or liquid, high-grade debt securities
having an aggregate net asset value at least equal to the accrued excess will
be maintained in a segregated account with the Fund's Custodian. To the extent
that the Portfolio enters into interest rate swaps on other than a net basis,
the amount maintained in a segregated account will be the full amount of the
Portfolio's obligations, if any, with respect to such interest rate swaps,
accrued on a daily basis. Inasmuch as segregated accounts are established for
these hedging transactions, the investment adviser and the Portfolio believe
such obligations do not constitute senior securities. If there is a default by
the other party to such a transaction, the Portfolio will have contractual
remedies pursuant to the agreement related to the transaction. The swap market
has grown substantially in recent years with a large number of banks and
investment banking firms. Since interest rate swaps are individually
negotiated, the Portfolio expects to achieve an acceptable degree of
correlation between its rights to receive interest on its portfolio securities
and its rights and obligations to receive and pay interest pursuant to
interest rate swaps. The risk of loss with respect to interest rate swaps is
limited to the net amount of interest payments that the Portfolio is
contractually obligated to make and will not exceed 5% of the Portfolio's net
 
                                      B-6
<PAGE>
 
assets. The Portfolio will enter into interest rate swaps only with parties
meeting creditworthiness standards approved by the Fund's Board of Directors.
The investment adviser will monitor the creditworthiness of such parties under
the supervision of the Board of Directors.
 
  INTEREST RATE FUTURES CONTRACTS. As a purchaser of an interest rate futures
contract (futures contract), the Portfolio incurs an obligation to take
delivery of a specified amount of the obligation underlying the futures
contract at a specified time in the future for a specified price. As a seller
of a futures contract, the Portfolio incurs an obligation to deliver the
specified amount of the underlying obligation at a specified time in return
for an agreed upon price.
 
  The Portfolio will purchase or sell futures contracts for the purpose of
hedging its portfolio (or anticipated portfolio) securities against changes in
prevailing interest rates. If the investment adviser anticipates that interest
rates may rise and, concomitantly, the price of U.S. Government or other debt
securities falls, the Portfolio may sell a futures contract. If declining
interest rates are anticipated, the Portfolio may purchase a futures contract
to protect against a potential increase in the price of U.S. Government or
other debt securities the Portfolio intends to purchase. Subsequently,
appropriate U.S. Government or other debt securities may be purchased by the
Portfolio in an orderly fashion; as securities are purchased, corresponding
futures positions would be terminated by offsetting sales of contracts. In
addition, futures contracts will be bought or sold in order to close out a
short or long position in a corresponding futures contract.
 
  Although most futures contracts call for actual delivery or acceptance of
securities, the contracts usually are closed out before the settlement date
without the making or taking of delivery. A futures contract sale is closed
out by effecting a futures contract purchase for the same aggregate amount of
the specific type of security and the same delivery date. If the sale price
exceeds the offsetting purchase price, the seller would be paid the difference
and would realize a gain. If the offsetting purchase price exceeds the sale
price, the seller would pay the difference and would realize a loss.
Similarly, a futures contract purchase is closed out by effecting a futures
contract sale for the same aggregate amount of the specific type of security
and the same delivery date. If the offsetting sale price exceeds the purchase
price, the purchaser would realize a gain, whereas if the purchase price
exceeds the offsetting sale price, the purchaser would realize a loss. There
is no assurance that the Portfolio will be able to enter into a closing
transaction.
 
  When the Portfolio enters into a futures contract it is initially required
to deposit with the Fund's Custodian, in a segregated account in the name of
the broker performing the transaction, an "initial margin" of cash or U.S.
Government securities equal to approximately 2-3% of the contract amount.
Initial margin requirements are established by the exchanges on which futures
contracts trade and may, from time to time, change. In addition, brokers may
establish margin deposit requirements in excess of those required by the
exchanges.
 
  Initial margin in futures transactions is different from margin in
securities transactions in that initial margin does not involve the borrowing
of funds by a broker's client but is, rather, a good faith deposit on the
futures contract which will be returned to the Portfolio upon the proper
termination of the futures contract. The margin deposits made are marked to
market daily and the Portfolio may be required to make subsequent deposits
into the segregated account, maintained at the Fund's Custodian for that
purpose, or cash or U.S. Government securities, called "variation margin," in
the name of the broker, which are reflective of price fluctuations in the
futures contract. Currently, interest rate futures contracts can be purchased
on debt securities such as U.S. Treasury Bills, Notes and Bonds, Eurodollar
instruments, GNMA Certificates and bank certificates of deposit.
 
  The Portfolio may purchase Eurodollar futures and options thereon, which are
essentially U.S. dollar-denominated futures contracts or options linked to
LIBOR. Eurodollar futures contracts are currently traded on the Chicago
Mercantile Exchange. They enable purchasers to obtain a fixed-rate for the
lending of funds and sellers to obtain a fixed-rate for borrowings. The
Portfolio would use Eurodollar futures contracts and options thereon to hedge
against changes in LIBOR, to which many interest rates swaps are linked.
 
  OPTIONS ON FUTURES CONTRACTS. The Portfolio may purchase call and put
options on futures contracts which are traded on an exchange and enter into
closing transactions with respect to such options to terminate an existing
position. An option on a futures contract gives the purchaser the right (in
return for the premium paid), and the writer the obligation, to assume a
position in a futures contract (a long position if the option is a call and a
short position if the option is a put) at a specified exercise price at any
time during the term of the option. Upon exercise of the option, the
assumption of offsetting futures positions by the writer and the holder of the
option will be accompanied by the delivery of the accumulated balance in the
writer's futures margin account, which represents the amount by which the
market price of the futures contract at the time of exercise exceeds, in the
case of a call, or is less than, in the case of a put, the exercise price of
the option on the futures contract.
 
  The Portfolio will purchase options on futures contracts for identical
purposes to those set forth above for the purchase of a futures contract
(purchase of a call option or sale of a put option) and the sale of a futures
contract (purchase of a put option or sale of a call option), or to close out
a long or short position in futures contracts. If, for example, the investment
adviser wished to protect
 
                                      B-7
<PAGE>
 
against an increase in interest rates and the resulting negative impact on the
value of a portion of its U.S. Government securities portfolio, it might
purchase a put option on an interest rate futures contract, the underlying
security of which correlates with the portion of the portfolio the investment
adviser seeks to hedge.
 
  LIMITATIONS ON FUTURES CONTRACTS AND OPTIONS ON FUTURES. Under regulations
of the Commodity Exchange Act, investment companies registered under the
Investment Company Act are exempt from the definition of "commodity pool
operator," subject to compliance with certain conditions. The exemption is
conditioned upon the Portfolio's purchasing and selling futures contracts and
options thereon for bona fide hedging transactions, except that the Portfolio
may purchase and sell futures contracts and options thereon for any other
purpose to the extent that the aggregate initial margin and option premiums do
not exceed 5% of the liquidation value of the Portfolio's total assets. The
Portfolio will use futures contracts and options thereon in a manner
consistent with these requirements.
 
  RISKS OF TRANSACTIONS IN FUTURES CONTRACTS AND OPTIONS THEREON. The
Portfolio may sell a futures contract to protect against the decline in the
value of U.S. Government securities and other debt securities held by the
Portfolio. However, it is possible that the futures market may advance and the
value of securities held in the Portfolio may decline. If this were to occur,
the Portfolio would lose money on the futures contracts and also experience a
decline of value in its portfolio securities. However, while this could occur
for a very brief period or to a very small degree, over time the market prices
of the securities of a diversified portfolio will tend to move in the same
direction as the prices of futures contracts.
 
  If the Portfolio purchases a futures contract to hedge against the increase
in value of U.S. Government securities it intends to buy, and the value of
such securities decreases, then the Portfolio may determine not to invest in
the securities as planned and will realize a loss on the futures contract that
is not offset by a reduction in the price of the securities.
 
  If the Portfolio maintains a short position in a futures contract, it will
cover this position by holding, in a segregated account maintained at the
Fund's Custodian, cash, U.S. Government securities or other liquid, high-grade
debt obligations equal in value (when added to any initial or variation margin
on deposit) to the market value of the securities underlying the futures
contract. Such a position may also be covered by owning the securities
underlying the futures contract, or by holding a call option permitting the
Portfolio to purchase the same contract at a price no higher than the price at
which the short position was established.
 
  In addition, if the Portfolio holds a long position in a futures contract,
it will hold cash, U.S. Government securities or other liquid, high-grade debt
obligations equal to the purchase price of the contract (less the amount of
initial or variation margin on deposit) in a segregated account maintained for
the Portfolio by the Fund's Custodian. Alternatively, the Portfolio could
cover its long position by purchasing a put option on the same futures
contract with an exercise price as high or higher than the price of the
contract held by the Portfolio.
 
  Exchanges limit the amount by which the price of a futures contract may move
on any day. If the price moves equal the daily limit on successive days, then
it may prove impossible to liquidate a futures position until the daily limit
moves have ceased. In the event of adverse price movements, the Portfolio
would continue to be required to make daily cash payments of variation margin
on open futures positions. In such situations, if the Portfolio has
insufficient cash, it may be disadvantageous to do so. In addition, the
Portfolio may be required to take or make delivery of the instruments
underlying interest rate futures contracts it holds at a time when it is
disadvantageous to do so. The ability to close out options and futures
positions could also have an adverse impact on the Portfolio's ability to
effectively hedge its portfolio.
 
  In the event of the bankruptcy of a broker through which the Portfolio
engages in transactions in futures or options thereon, the Portfolio could
experience delays and/or losses in liquidating open positions purchased or
sold through the broker and/or incur a loss of all or part of its margin
deposits with the broker. Transactions are entered into by the Portfolio only
with brokers or financial institutions deemed creditworthy by the investment
adviser.
 
  While the futures contracts and options transactions to be engaged in by the
Portfolio for the purpose of hedging the Portfolio's securities are not
speculative in nature, there are risks inherent in the use of such
instruments. One such risk which may arise in employing futures contracts to
protect against the price volatility of the Portfolio's securities is that the
prices of securities subject to futures contracts (and thereby the futures
contract prices) may correlate imperfectly with the behavior of the cash
prices of the Portfolio's securities. Another such risk is that prices of
interest rate futures contracts may not move in tandem with the changes in
prevailing interest rates against which the Portfolio seeks a hedge. A
correlation may also be distorted by the fact that the futures market is
dominated by short-term traders seeking to profit from the difference between
a contract or security price objective and their cost of borrowed funds. Such
distortions are generally minor and would diminish as the contract approached
maturity.
 
  There may exist an imperfect correlation between the price movements of
futures contracts purchased by the Portfolio and the movements in the prices
of the securities which are the subject of the hedge. If participants in the
futures market elect to close out their contracts through offsetting
transactions rather than meet margin deposit requirements, distortions in the
normal relationships between the debt securities and futures market could
result. Price distortions could also result if investors in futures contracts
elect to
 
                                      B-8
<PAGE>
 
make or take delivery of underlying securities rather than engage in closing
transactions due to the resultant reduction in the liquidity of the futures
market. In addition, due to the fact that, from the point of view of
speculators, the deposit requirements in the futures markets are less onerous
than margin requirements in the cash market, increased participation by
speculators in the futures market could cause temporary price distortions. Due
to the possibility of price distortions in the futures market and because of
the imperfect correlation between movements in the prices of U.S. Government
securities and movements in the prices of futures contracts, a correct
forecast of interest rate trends by the investment adviser may still not
result in a successful hedging transaction.
 
  There is no assurance that a liquid secondary market will exist for the
futures contracts and options thereon in which the Portfolio may invest. In
the event a liquid market does not exist, it may not be possible to close out
a futures position, and in the event of adverse price movements, the Portfolio
would continue to be required to make daily cash payments of variation margin.
In addition, limitations imposed by an exchange or board of trade on which
futures contracts are traded may compel or prevent the Portfolio from closing
out a contract which may result in reduced gain or increased loss to the
Portfolio. The absence of a liquid market in futures contracts might cause the
Portfolio to make or take delivery of the underlying securities at a time when
it may be disadvantageous to do so.
 
  Compared to the purchase or sale of futures contracts, the purchase of call
or put options on futures contracts involves less potential risk to the
Portfolio because the maximum amount at risk is the premium paid for the
options (plus transaction costs). However, there may be circumstances when the
purchase of a call or put option on a futures contract would result in a loss
to the Portfolio notwithstanding that the purchase or sale of a futures
contract would not result in a loss, as in the instance where there is no
movement in the prices of the futures contracts or underlying U.S. Government
securities.
 
  The Portfolio will limit its use of futures contracts and options thereon to
the purchase of Eurodollar futures contracts and options thereon linked to
LIBOR.
 
  ILLIQUID SECURITIES. The Portfolio may invest up to 15% of its net assets
(determined at the time of investment) in illiquid securities including
securities for which there are legal or contractual restrictions on resale,
securities for which there is no readily available market and repurchase
agreements having maturities of more than seven days.
 
  When the Portfolio enters into interest rate swaps on other than a net
basis, the entire amount of the Portfolio's obligations, if any, with respect
to such interest rate swaps will be treated as illiquid. To the extent that
the Portfolio enters into interest rate swaps on a net basis, the net amount
of the excess, if any, of the Portfolio's obligations over its entitlements
with respect to each interest rate swap will be treated as illiquid.
 
  PORTFOLIO TURNOVER. The Income Portfolio's turnover rates in 1993, 1992 and
1991 were 137%, 91% and 117%, respectively. The investment adviser expects
that, under normal circumstances, the Portfolio's turnover rate may be as high
as 200%. See "How the Fund Invests--Investment Objective and Policies--Other
Investments and Policies" in the Prospectus.
 
 
                            INVESTMENT RESTRICTIONS
 
  The following restrictions are fundamental policies. Fundamental policies
are those which cannot be changed without the approval of the holders of a
majority of the outstanding voting securities of the Portfolio. A "majority of
the outstanding voting securities" of the Portfolio, when used in this
Statement of Additional Information, means the lesser of (i) 67% of the voting
shares represented at a meeting at which more than 50% of the outstanding
voting shares are present in person or represented by proxy or (ii) more than
50% of the outstanding voting shares.
 
  The Portfolio may not:
 
  1. Purchase securities on margin (but the Portfolio may obtain such short-
term credits as may be necessary for the clearance of transactions); provided
that the deposit or payment by the Fund of initial or variation margin in
connection with options or futures contracts is not considered the purchase of
a security on margin.
 
  2. Make short sales of securities or maintain a short position, except short
sales "against the box".
 
  3. Issue senior securities, borrow money or pledge its assets, except that
the Portfolio may borrow up to 20% of the value of its total assets
(calculated when the loan is made) from banks for temporary, extraordinary or
emergency purposes or for the clearance of transactions and may pledge up to
20% of the value of its total assets to secure such borrowings. The purchase
or sale of securities on a "when-issued" or delayed delivery basis, and the
purchase and sale of financial futures contracts and collateral arrangements
with respect thereto and with respect to interest rate swap transactions,
covered dollar rolls and reverse repurchase agreements, are not deemed to be a
pledge of assets and such arrangements are not deemed to be the issuance of a
senior security. The Portfolio will not purchase portfolio securities if its
borrowings exceed 5% of its net assets.
 
 
                                      B-9
<PAGE>
 
  4. Purchase any security (other than obligations of the U.S. Government, its
agencies and instrumentalities including municipal obligations and obligations
guaranteed as to principal and interest) if as a result: (i) with respect to
75% of its net assets, more than 5% of the Portfolio's total assets (determined
at the time of investment) would then be invested in securities of a single
issuer or (ii) 25% or more of the Portfolio's total assets (determined at the
time of investment) would be invested in one or more issuers having their
principal business activities in the same industry.
 
  5. Purchase securities, other than obligations of the U.S. Government, its
agencies or instrumentalities, of any issuer having a record, together with
predecessors, of less than three years of continuous operations if, immediately
after such purchase, more than 5% of such Portfolio's total assets would be
invested in such securities.
 
  6. Buy or sell real estate or interests in real estate, except that the
Portfolio may purchase and sell mortgage-backed securities, securities
collateralized by mortgages, securities which are secured by real estate,
securities of companies which invest or deal in real estate and publicly traded
securities of real estate investment trusts. The Portfolio may not purchase
interests in real estate limited partnerships which are not readily marketable.
 
  7. Act as underwriter except to the extent that, in connection with the
disposition of portfolio securities, it may be deemed to be an underwriter
under certain federal securities laws.
 
  8. Make investments for the purpose of exercising control or management.
 
  9. Invest in securities of other registered investment companies, except by
purchases in the open market involving only customary brokerage commissions and
as a result of which not more than 10% of its total assets (determined at the
time of investment) would be invested in such securities, or except as part of
a merger, consolidation or other acquisition.
 
  10. Invest in interests in oil, gas or other mineral exploration or
development programs, except that the Portfolio may invest in the securities of
companies which invest in or sponsor such programs.
 
  11. Make loans, except through (i) repurchase agreements and (ii) loans of
portfolio securities (limited to 30% of the value of the Portfolio's total
assets).
 
  12. Purchase common stock or other voting securities, preferred stock,
warrants or other equity securities, except as may be permitted by restriction
number 9.
 
  13. Buy or sell commodities or commodity contracts, except that the Portfolio
may purchase and sell financial futures contracts and options thereon.
 
  Whenever any fundamental investment policy or investment restriction states a
maximum percentage of the Portfolio's assets, it is intended that if the
percentage limitation is met at the time the investment is made, a later change
in percentage resulting from changing total or net asset values will not be
considered a violation of such policy. However, in the event that the
Portfolio's asset coverage for borrowing falls below 300%, the Portfolio will
take prompt action to reduce its borrowings, as required by applicable law.
 
  In order to comply with certain state "blue sky" restrictions, the Portfolio
will not as a matter of operating policy:
 
  1. Invest in oil, gas and mineral leases or programs.
 
  2. Purchase warrants if as a result the Portfolio would then have more than
5% of its net assets (determined at the time of investment) invested in
warrants. Warrants will be valued at the lower of cost or market and investment
in warrants which are not listed on the New York Stock Exchange or American
Stock Exchange will be limited to 2% of the Portfolio's net assets (determined
at the time of investment). For the purpose of this limitation, warrants
acquired in units or attached to securities are deemed to be without value.
 
  3. Purchase securities of other registered investment companies, except in
connection with a merger, consolidation, reorganization or acquisition of
assets.
 
  4. Invest in securities of any issuer if, to the knowledge of the Portfolio,
any officer or director of the Portfolio or the Portfolio's Manager or
Subadviser owns more than 1/2 of 1% of the outstanding securities of such
issuer, and such officers and directors who own more than 1/2 of 1% own in the
aggregate more than 5% of the outstanding securities of such issuer.
 
  5. Except with respect to short sales against the box, make short sales
provided that short sales will only be made in those securities that are listed
on a national securities exchange and the value of the short sales of the
securities of any one issuer shall not exceed the lesser of 2% of the value of
the Portfolio's net assets, or 2% of the securities of any one issuer.

  Directors and officers of the Fund are also trustees, directors and officers
of some or all of the other investment companies distributed by Prudential
Securities or Prudential Mutual Fund Distributors, Inc.
 
  The officers conduct and supervise the daily business operations of the Fund,
while the Directors, in addition to their functions set forth under "Manager"
and "Distributor," review such actions and decide on general policy.
 
  The Fund pays each of its Directors who is not an affiliated person of PMF
annual compensation of $6,000, in addition to certain out-of-pocket expenses.
 
  Directors may receive their Director's fee pursuant to a deferred fee
agreement with the Fund. Under the terms of the agreement, the Fund accrues
daily the amount of such Director's fee which accrues interest at a rate
equivalent to the prevailing rate applicable to 90-day U.S. Treasury Bills at
the beginning of each calendar quarter or, pursuant to an SEC exemptive order,
at the daily rate of return of the Fund. Payment of the interest so accrued is
also deferred and accruals become payable at the option of the Director. The
Fund's obligation to make payments of deferred Director's fees, together with
interest thereon, is a general obligation of the Fund.
 
  As of June 17, 1994, the Directors and officers of the Fund, as a group,
beneficially owned less than one percent of the outstanding shares of common
stock of the Portfolio.
 
  As of June 17, 1994, Prudential Securities was record holder for other
beneficial owners of 7,726,732 Class A shares (81% of the outstanding shares)
and 9,311,768 Class B shares (75.8% of the outstanding shares) of the
Portfolio. In the event of any meetings of shareholders, Prudential Securities
will forward, or cause the forwarding of, proxy material to the beneficial
owners for which it is the record owner.
 
                                    MANAGER
 
  The manager of the Fund is Prudential Mutual Fund Management, Inc. (PMF or
the Manager), One Seaport Plaza, New York, New York 10292. PMF serves as
manager to all of the other investment companies that, together with the Fund,
comprise the Prudential Mutual Funds. See "How the Fund is Managed--Manager" in
the Prospectus. As of June 30, 1994, PMF managed and/or administered open-end
and closed-end management investment companies with assets of approximately $47
billion. According to the Investment Company Institute, as of April 30, 1994,
the Prudential Mutual Funds were the 12th largest family of mutual funds in the
United States.
 
                                      B-12

  Pursuant to the Management Agreement with the Fund (the Management
Agreement), PMF, subject to the supervision of the Fund's Board of Directors
and in conformity with the stated policies of the Fund, manages both the
investment operations of the Fund and the composition of the Fund's portfolio,
including the purchase, retention, disposition and loan of securities. In
connection therewith, PMF is obligated to keep certain books and records of
the Fund. PMF also administers the Fund's corporate affairs and, in connection
therewith, furnishes the Fund with office facilities, together with those
ordinary clerical and bookkeeping services which are not being furnished by
State Street Bank and Trust Company, the Fund's custodian, and Prudential
Mutual Fund Services, Inc. (PMFS or the Transfer Agent), the Fund's transfer
and dividend disbursing agent. The management services of PMF for the Fund are
not exclusive under the terms of the Management Agreement and PMF is free to,
and does, render management services to others.
 
  For its services, PMF receives, pursuant to the Management Agreement, a fee
at an annual rate of .40 of 1% of the average daily net assets of the
Portfolio. The fee is computed daily and payable monthly. The Management
Agreement also provides that, in the event the expenses of the Portfolio
(including the fees of PMF, but excluding interest, taxes, brokerage
commissions, distribution fees and litigation and indemnification expenses and
other extraordinary expenses not incurred in the ordinary course of the Fund's
business) for any fiscal year exceed the lowest applicable annual expense
limitation established and enforced pursuant to the statutes or regulations of
any jurisdiction in which the Portfolio's shares are qualified for offer and
sale, the compensation due to PMF will be reduced by the amount of such
excess. Reductions in excess of the total compensation payable to PMF will be
paid by PMF to the Portfolio. No such reductions were required during the
fiscal year ended December 31, 1993. Currently, the Fund believes that the
most restrictive expense limitation of state securities commissions is 2 1/2%
of the Portfolio's average daily net assets up to $30 million, 2% of the next
$70 million of such assets and 1 1/2% of such assets in excess of $100
million.
 
  In connection with its management of the corporate affairs of the Fund, PMF
bears the following expenses:
 
  (a) the salaries and expenses of all of its and the Fund's personnel except
the fees and expenses of Directors who are not affiliated persons of PMF or
the Fund's investment adviser;
 
  (b) all expenses incurred by PMF or by the Fund in connection with managing
the ordinary course of the Fund's business, other than those assumed by the
Fund as described below; and
 
  (c) the costs and expenses payable to The Prudential Investment Corporation
(PIC) pursuant to the subadvisory agreement between PMF and PIC (the
Subadvisory Agreement).
 
  Under the terms of the Management Agreement, the Portfolio is responsible
for the payment of the following expenses: (a) the fees payable to the
Manager, (b) the fees and expenses of Directors who are not affiliated persons
of the Manager or of the Fund's investment adviser, (c) the fees and certain
expenses of the Custodian and Transfer and Dividend Disbursing Agent,
including the cost of providing records to the Manager in connection with its
obligation of maintaining required records of the Portfolio and of pricing the
Portfolio's shares, (d) the charges and expenses of legal counsel and
independent accountants for the Fund, (e) brokerage commissions and any issue
or transfer taxes chargeable to the Portfolio in connection with its
securities transactions, (f) all taxes and corporate fees payable by the
Portfolio to governmental agencies, (g) the fees of any trade associations of
which the Fund may be a member, (h) the cost of stock certificates
representing shares of the Portfolio, (i) the cost of fidelity and liability
insurance, (j) the fees and expenses involved in registering and maintaining
registration of the Portfolio and of its shares with the SEC, registering the
Portfolio and qualifying its shares under state securities laws, including the
preparation and printing of the Fund's registration statements and
prospectuses for such purposes, (k) allocable communications expenses with
respect to investor services and all expenses of shareholders' and Directors'
meetings and of preparing, printing and mailing reports, proxy statements and
prospectuses to shareholders in the amount necessary for distribution to the
shareholders, (l) litigation and indemnification expenses and other
extraordinary expenses not incurred in the ordinary course of the Fund's
business and (m) distribution fees.
 
  The Management Agreement provides that PMF will not be liable for any error
of judgment or for any loss suffered by the Fund in connection with the
matters to which the Management Agreement relates, except a loss resulting
from willful misfeasance, bad faith, gross negligence or reckless disregard of
duty. The Management Agreement provides that it will terminate automatically
if assigned, and that it may be terminated without penalty by either party
upon not more than 60 days' nor less than 30 days' written notice. The
Management Agreement will continue in effect for a period of more than two
years from the date of execution only so long as such continuance is
specifically approved at least annually in conformity with the Investment
Company Act. The Management Agreement was last approved by the Board of
Directors of the Fund, including a majority of the Directors who are not
parties to the contract or interested persons of any such party as defined in
the Investment Company Act, on June 1, 1994 and by shareholders of the
Portfolio on April 25, 1990.
 
  For the fiscal year ended December 31, 1993, PMF received a management fee
of $736,171, for the Portfolio. For the fiscal year ended December 31, 1992,
PMF received a management fee of $280,988, net of waiver of $152,065, for the
Portfolio. For the year ended December 31, 1991, the Fund did not pay a
management fee to PMF with respect to the Portfolio. In addition, PMF
voluntarily subsidized 75% of the Portfolio's expenses (except for management
and distribution fees) until July 1, 1991, at which time the subsidy level was
reduced to 25% of such expenses. The subsidy was eliminated on December 2,
1991. The Portfolio is not required to reimburse PMF for such fee waiver and
subsidy.

  Without the effect of the management and distribution fee waivers and/or
expense subsidies, per share expenses for the Class A shares of the Portfolio
would have been $.10 and $.11 for the years ended December 31, 1992 and 1991
respectively. Expenses of the Class A shares of the Portfolio, including
distribution fees, would have been .83% and .97% of the Portfolio's average
daily net assets for the years ended December 31, 1992 and 1991, respectively.
Expenses of the Class A shares of the Portfolio, excluding distribution fees,
would have been .73% and .87%, of the Portfolio's average daily net assets for
the years ended December 31, 1992 and 1991, respectively.
 
  PMF has entered into the Subadvisory Agreement with PIC (the Subadviser).
The Subadvisory Agreement provides that PIC will furnish investment advisory
services in connection with the management of the Fund. In connection
therewith, PIC is obligated to keep certain books and records of the
Portfolio. PMF continues to have responsibility for all investment advisory
services pursuant to the Management Agreement and supervises PIC's performance
of such services. PIC is reimbursed by PMF for the reasonable costs and
expenses incurred by PIC in furnishing those services.
 
  The Subadvisory Agreement was last approved by the Board of Directors,
including a majority of the Directors who are not parties to the contract or
interested persons of any such party as defined in the Investment Company Act
on June 1, 1994 and by shareholders of the Portfolio on April 25, 1990.
 
  The Subadvisory Agreement provides that it will terminate in the event of
its assignment (as defined in the Investment Company Act) or upon the
termination of the Management Agreement. The Subadvisory Agreement may be
terminated by the Fund, PMF or PIC upon not more than 60 days', nor less than
30 days', written notice. The Subadvisory Agreement provides that it will
continue in effect for a period of more than two years from its execution only
so long as such continuance is specifically approved at least annually in
accordance with the requirements of the Investment Company Act.
 
  The Manager and the Subadviser are subsidiaries of The Prudential Insurance
Company of America (Prudential) which, as of December 31, 1993, is one of the
largest financial institutions in the world and the largest insurance company
in North America. Prudential has been engaged in the insurance business since
1875. In July 1993, Institutional Investor ranked Prudential the third largest
institutional money manager of the 300 largest money management organizations
in the United States as of December 31, 1992.
 
                                  DISTRIBUTOR
 
  Prudential Mutual Fund Distributors, Inc. (PMFD), One Seaport Plaza, New
York, New York 10292, acts as the distributor of the Class A shares of the
Portfolio. Prudential Securities Incorporated, One Seaport Plaza, New York,
New York 10292 (Prudential Securities), acts as the distributor of the Class B
and Class C shares of the Portfolio.
 
  Pursuant to separate Distribution and Service Plans (the Class A Plan, the
Class B Plan and the Class C Plan, collectively, the Plans) adopted by the
Portfolio under Rule 12b-1 under the Investment Company Act and separate
distribution agreements (the Distribution Agreements), PMFD and Prudential
Securities (collectively, the Distributor) incur the expenses of distributing
the Portfolio's Class A, Class B and Class C shares. See "How the Fund is
Managed--Distributor" in the Prospectus.
 
  On June 7, 1989 and September 13, 1989, the Board of Directors, including a
majority of the Directors who are not interested persons of the Fund and who
have no direct or indirect financial interest in the operation of the Class A
or Class B Plan or in any agreement related to either Plan (the Rule 12b-1
Directors), at meetings called for the purpose of voting on each Plan,
approved an amended and restated plan of distribution of the Class A shares of
the Fund (the Class A Plan) and a plan of distribution for the Class B shares
of the Fund (the Class B Plan). The Class A Plan was last approved by
shareholders of the Fund on April 25, 1990. On September 9, 1992, the Board of
Directors reauthorized the categorization of the shares of the Fund as Class A
shares and the implementation of the Class B Plan. The Board of Directors
reapproved the Class B Plan as restated on September 9, 1992 and the Class B
Plan was approved by the sole holder of Class B shares on September 30, 1992.
On June 9, 1993, the Board of Directors, including a majority of the Rule 12b-
1 Directors, at a meeting called for the purpose of voting on each Plan,
approved the continuance of the Plans and Distribution Agreements and approved
modifications of the Fund's Class A and Class B Plans and Distribution
Agreements to conform them with recent amendments to the National Association
of Securities Dealers, Inc. (NASD) maximum sales charge rule described below.
As so modified, the Class A Plan provides that (i) up to .10 of 1% of the
average daily net assets of the Class A shares may be used to pay for personal
service and/or the maintenance of shareholder accounts (service fee) and (ii)
total distribution fees (including the service fee of .10 of 1%) may not
exceed .10 of 1%. As so modified, the Class B Plan provides that (i) up to .25
of 1% of the average daily net assets of the Class B shares may be paid as a
service fee and (ii) up to .75 of 1% (not including the service fee) may be
used as reimbursement for distribution-related expenses with respect to the
Class B shares (asset-based sales charge). The Distributor has agreed to limit
the distribution fee with respect to the Class B shares to no more than .75 of
1% (including the service fee of .10 of 1%) for the fiscal year ending
December 31, 1994. On July 15, 1993, the Board of Directors authorized the
creation of the Municipal Income Portfolio and reclassified the Fund's
existing shares as shares of the Income Portfolio.
 
 
                                     B-14
<PAGE>
 
  On May 3, 1993, the Board of Directors, including a majority of the Rule
12b-1 Directors, at a meeting called for the purpose of voting on each Plan,
adopted plans of distribution for the Class C shares of the Portfolio and
approved further amendments to the plans of distribution for the Portfolio's
Class A and Class B shares, changing them from reimbursement type plans to
compensation type plans. In addition, on March 4, 1994, the Board of Directors
approved, subject to shareholder approval, amendments to the Class A Plan for
the Portfolio to increase the distribution fee. As so amended, the Class A
Plan provides that (i) up to .25 of 1% of the average daily net assets of the
Class A shares may be used as a service fee and (ii) total distribution fees
(including the service fee of .25 of 1%) may not exceed .30 of 1%. The
Distributor has agreed to limit the distribution fee with respect to Class A
shares to .10 of 1% for the fiscal year ending December 31, 1994. The Plans
were last approved by the Directors, including a majority of the Rule 12b-1
Directors, on June 1, 1994. The Class A Plan, as amended, was approved by
Class A and Class B shareholders, and the Class B Plan, as amended, was
approved by Class B shareholders, on July 19, 1994. The Class C Plan was
approved by the sole shareholder of Class C shares on August 1, 1994.
 
  CLASS A PLAN. For the year ended December 31, 1993, PMFD received payments
of $114,728 under the Class A Plan. This amount was primarily expended for
payment of account servicing fees to financial advisers and other persons who
sell Class A shares. For the fiscal year ended December 31, 1993, PMFD
received approximately $669,100 in initial sales charges.
 
  CLASS B PLAN. For the fiscal year ended December 31, 1993, Prudential
Securities received $589,173 from the Fund under the Class B Plan and spent
approximately $2,786,300 in distributing the Class B shares of the Portfolio.
It is estimated that of the latter amount approximately 17.4% ($485,000) was
spent on compensation to Pruco Securities Corporation, an affiliated broker-
dealer, for commissions to its representatives and other expenses, including
an allocation on account of overhead and other branch office distribution-
related expenses, incurred by it for distribution of the Portfolio's shares;
approximately 2.7% ($74,000) on prospectus and other printing costs;
approximately 1.7% ($47,200) on interest and/or carrying costs and 78.2%
($2,180,100) on the aggregate of (i) payments of commissions and account
servicing fees to financial advisers 31.6% ($881,300) and (ii) an allocation
on account of overhead and other branch office distribution-related expenses
46.6% ($1,298,800). The term "overhead and other branch office distribution-
related expenses" represents (a) the expenses of operating Prudential
Securities' branch offices in connection with the sale of shares of the
Portfolio, including lease costs, the salaries and employee benefits of
operations and sales support personnel, utility costs, communications costs
and the costs of stationery and supplies, (b) the costs of client sales
seminars, (c) expenses of mutual fund sales coordinators to promote the sale
of shares of the Portfolio, and (d) other incidental expenses relating to
branch promotion of Fund sales.
 
  Prudential Securities also receives the proceeds of contingent deferred
sales charges paid by investors upon certain redemptions of Class B shares.
See "Shareholder Guide--How to Sell Your Shares--Contingent Deferred Sales
Charges" in the Prospectus. For the fiscal year ended December 31, 1993,
Prudential Securities received approximately $86,000 in contingent deferred
sales charges.
 
  CLASS C PLAN. Prudential Securities receives the proceeds of contingent
deferred sales charges paid by investors upon certain redemptions of Class C
shares. See "Shareholder Guide--How to Sell Your Shares--Contingent Deferred
Sales Charges" in the Prospectus. Prior to the date of this Statement of
Additional Information, no distribution expenses were incurred under the Class
C Plans.
 
  The Class A, Class B and Class C Plans continue in effect from year to year,
provided that each such continuance is approved at least annually by a vote of
the Board of Directors, including a majority vote of the Rule 12b-1 Directors,
cast in person at a meeting called for the purpose of voting on such
continuance. The Plans may be terminated at any time, without penalty, by the
vote of a majority of the Rule 12b-1 Directors or by the vote of the holders
of a majority of the outstanding shares of the applicable class ofthe
Portfolio on not more than 30 days' written notice to any other party to the
Plans. The Plans may not be amended to increase materially the amounts to be
spent for the services described therein without approval by the shareholders
of the applicable class (by both Class A and Class B shareholders, voting
separately, in the case of material amendments to the Class A Plan), and all
material amendments are required to be approved by the Board of Directors in
the manner described above. Each Plan will automatically terminate in the
event of assignment. The Fund will not be contractually obligated to pay
expenses incurred under any Plan if it is terminated or not continued.
 
  Pursuant to each Plan, the Board of Directors will review at least quarterly
a written report of the distribution expenses incurred on behalf of each class
of shares of the Portfolios by the Distributor. The report will include an
itemization of the distribution expenses and the purposes of such
expenditures. In addition, as long as the Plans remain in effect, the
selection and nomination of Rule 12b-1 Directors shall be committed to the
Rule 12b-1 Directors.
 
  Pursuant to each Distribution Agreement, the Fund has agreed to indemnify
PMFD and Prudential Securities to the extent permitted by applicable law
against certain liabilities under the Securities Act of 1933, as amended. Each
Distribution Agreement was last approved by the Board of Directors, including
a majority of the Rule 12b-1 Directors, on June 1, 1994.
 
  NASD MAXIMUM SALES CHARGE RULE. Pursuant to rules of the NASD, the
Distributor is required to limit aggregate initial sales charges, deferred
sales charges and asset-based sales charges to 6.25% of total gross sales of
each class of shares of the Portfolio.
 
                                     B-15
<PAGE>
 
Interest charges on unreimbursed distribution expenses equal to the prime rate
plus one percent per annum may be added to the 6.25% limitation. Sales from
the reinvestment of dividends and distributions are not included in the
calculation of the 6.25% limitation. The annual asset-based sales charge on
shares of the Portfolio may not exceed .75 of 1% per class. The 6.25%
limitation applies to each class of the Portfolio rather than on a per
shareholder basis. If aggregate sales charges were to exceed 6.25% of total
gross sales of any class of the Portfolio, all sales charges on shares of that
class would be suspended.
 
                            PORTFOLIO TRANSACTIONS
 
  The Manager is responsible for decisions to buy and sell securities for the
Fund, the selection of brokers and dealers to effect the transactions and the
negotiation of brokerage commissions, if any. For purposes of this section,
the term "Manager" includes the Subadviser. The Fund does not normally incur
any brokerage commission expense on such transactions. The instruments
purchased by the Fund are generally traded on a "net" basis, with dealers
acting as principal for their own accounts without a stated commission,
although the price of the security usually includes a profit to the dealer. In
underwritten offerings, securities are purchased at a fixed price which
includes an amount of compensation to the underwriter, generally referred to
as the underwriter's concession or discount. On occasion, certain money market
instruments may be purchased directly from an issuer, in which case no
commissions or discounts are paid. Portfolio securities may not be purchased
from any underwriting or selling syndicate of which Prudential Securities (or
any affiliate), during the existence of the syndicate, is a principal
underwriter (as defined in the Investment Company Act), except in accordance
with the rules of the SEC. This limitation, in the opinion of the Fund, will
not significantly affect the Portfolio's ability to pursue its present
investment objective. However, in the future in other circumstances, the
Portfolio may be at a disadvantage because of this limitation in comparison to
other funds with similar objectives but not subject to such limitations.
 
  In placing orders for portfolio securities of the Fund, the Manager is
required to give primary consideration to obtaining the most favorable price
and efficient execution. This means that the Manager will seek to execute each
transaction at a price and commission, if any, which provide the most
favorable total cost or proceeds reasonably attainable under the
circumstances. While the Manager generally seeks reasonably competitive
spreads or commissions, the Fund will not necessarily be paying the lowest
spread or commission available. Within the framework of this policy, the
Manager may consider research and investment services provided by brokers or
dealers who effect or are parties to portfolio transactions of the Fund, the
Manager or the Manager's other clients. Such research and investment services
are those which brokerage houses customarily provide to institutional
investors and include statistical and economic data and research reports on
particular companies and industries. Such services are used by the Manager in
connection with all of its investment activities, and some of such services
obtained in connection with the execution of transactions for the Fund may be
used in managing other investment accounts. Conversely, brokers furnishing
such services may be selected for the execution of transactions for such other
accounts, whose aggregate assets are far larger than the Fund's, and the
services furnished by such brokers may be used by the Manager in providing
investment management for the Fund. While such services are useful and
important in supplementing its own research and facilities, the Manager
believes that the value of such services is not determinable and does not
significantly reduce expenses. The Fund does not reduce the advisory fee it
pays to the Manager by any amount that may be attributed to the value of such
services.
 
  Subject to the above considerations, Prudential Securities may act as a
securities broker for the Fund. In order for Prudential Securities (or any
affiliate) to effect any portfolio transactions for the Fund, the commissions,
fees or other remuneration received by Prudential Securities (or any
affiliate) must be reasonable and fair compared to the commissions, fees or
other remuneration paid to other brokers in connection with comparable
transactions involving similar securities being purchased or sold during a
comparable period of time. This standard would allow Prudential Securities (or
any affiliate) to receive no more than the remuneration which would be
expected to be received by an unaffiliated broker in a commensurate arm's-
length transaction. Furthermore, the Board of Directors of the Fund, including
a majority of the non-interested Directors, has adopted procedures which are
reasonably designed to provide that any commissions, fees or other
remuneration paid to Prudential Securities (or any affiliate) are consistent
with the foregoing standard. Brokerage transactions with Prudential Securities
are also subject to such fiduciary standards as may be imposed by applicable
law. For the fiscal years ended December 31, 1993, 1992 and 1991, the Fund
paid no brokerage commissions.
 
                    PURCHASE AND REDEMPTION OF FUND SHARES
 
  Shares of the Portfolio may be purchased at a price equal to the next
determined net asset value per share plus a sales charge which, at the
election of the investor, may be imposed either (i) at the time of purchase
(Class A shares) or (ii) on a deferred basis (Class B or Class C shares) See
"Shareholder Guide--How to Buy Shares of the Fund" in the Prospectus.
 
  Each class of shares represents an interest in the same portfolio of
investments of the Portfolio and has the same rights, except that (i) each
class bears the separate expenses of its Rule 12b-1 distribution and service
plan, (ii) each class has exclusive voting rights with respect to its plan
(except that the Fund has agreed with the SEC in connection with the offering
of a conversion feature on Class B shares to submit any amendment of the Class
A distribution and service plan to both Class A and Class B shareholders) and
(iii) only Class B shares have a conversion feature. See "Distributor." Each
class also has separate exchange privileges. See "Shareholder Investment
Account--Exchange Privilege."

REDUCTION AND WAIVER OF INITIAL SALES CHARGES--CLASS A SHARES
 
  COMBINED PURCHASE AND CUMULATIVE PURCHASE PRIVILEGE. If an investor or
eligible group of related investors purchases Class A shares of the Portfolio
concurrently with Class A shares of other Prudential Mutual Funds, the
purchases may be combined to take advantage of the reduced sales charges
applicable to larger purchases. See the table of breakpoints under
"Shareholder Guide--Alternative Purchase Plan" in the Prospectus.
 
  An eligible group of related Fund investors includes any combination of the
following:
 
   (a) an individual;
 
   (b) the individual's spouse, their children and their parents;
 
   (c) the individual's and spouse's Individual Retirement Account (IRA);
 
   (d) any company controlled by the individual (a person, entity or group
       that holds 25% or more of the outstanding voting securities of a
       company will be deemed to control the company, and a partnership will
       be deemed to be controlled by each of its general partners);
 
   (e) a trust created by the individual, the beneficiaries of which are the
       individual, his or her spouse, parents or children;
 
   (f) a Uniform Gifts to Minors Act/Uniform Transfers to Minors Act account
       created by the individual or the individual's spouse; and
 
   (g) one or more employee benefit plans of a company controlled by an
       individual.
 
  In addition, an eligible group of related investors in the Portfolio may
include an employer (or group of related employers) and one or more qualified
retirement plans of such employer or employers (an employer controlling,
controlled by or under common control with another employer is deemed related
to that employer).
 
  The Distributor must be notified at the time of purchase that the investor
is entitled to a reduced sales charge. The reduced sales charges will be
granted subject to confirmation of the investor's holdings. The Combined
Purchase and Cumulative Purchase Privilege does not apply to individual
participants in any retirement or group plans.
 
  RIGHTS OF ACCUMULATION. Reduced sales charges are also available through
Rights of Accumulation, under which an investor or an eligible group of
related investors, as described above under "Combined Purchase and Cumulative
Purchase Privilege," may aggregate the value of their existing holdings of the
shares of the Fund and shares of other Prudential Mutual Funds (excluding
money market funds other than those acquired pursuant to the exchange
privilege) to determine the reduced sales charge. However, the value of shares
held directly with the Transfer Agent and through Prudential Securities will
not be aggregated to determine the value of the reduced sales charge. All
shares must be held either directly with the Transfer Agent or through
Prudential Securities. The value of existing holdings for purposes of
determining the reduced sales charge is calculated using the maximum offering
price (net asset value plus maximum sales charge) as of the previous business
day. See "How the Fund Values Its Shares" in the Prospectus. The
 
                                     B-17
<PAGE>
 
Distributor must be notified at the time of purchase that the investor is
entitled to a reduced sales charge. The reduced sales charges will be granted
subject to confirmation of the investor's holdings. Rights of Accumulation are
not available to individual participants in any retirement or group plans.
 
  LETTERS OF INTENT. Reduced sales charges are available to investors (or an
eligible group of related investors) who enter into a written Letter of Intent
providing for the purchase, within a thirteen-month period, of shares of the
Fund and shares of other Prudential Mutual Funds. All shares of the Fund and
shares of other Prudential Mutual Funds (excluding money market funds other
than those acquired pursuant to the exchange privilege) which were previously
purchased and are still owned are also included in determining the applicable
reduction. However, the value of shares held directly with the Transfer Agent
and through Prudential Securities will not be aggregated to determine the
value of the reduced sales charge. All shares must be held either directly
with the Transfer Agent or through Prudential Securities. The Distributor must
be notified at the time of purchase that the investor is entitled to a reduced
sales charge. The reduced sales charges will be granted subject to
confirmation of the investors holdings. Letters of Intent are not available to
individual participants in any retirement or group plans.
 
  A Letter of Intent permits a purchaser to establish a total investment goal
to be achieved by any number of investments over a thirteen-month period. Each
investment made during the period will receive the reduced sales charge
applicable to the amount represented by the goal, as if it were a single
investment. Escrowed Class A shares totaling 5% of the dollar amount of the
Letter of Intent will be held by the Transfer Agent in the name of the
purchaser. The effective date of a Letter of Intent may be back-dated up to 90
days, in order that any investments made during this 90-day period, valued at
the purchaser's cost, can be applied to the fulfillment of the Letter of
Intent goal.
 
  The Letter of Intent does not obligate the investor to purchase, nor the
Fund to sell, the indicated amount. In the event the Letter of Intent goal is
not achieved within the thirteen-month period, the purchaser is required to
pay the difference between the sales charge otherwise applicable to the
purchases made during this period and sales charges actually paid. Such
payment may be made directly to the Distributor or, if not paid, the
Distributor will liquidate sufficient escrowed shares to obtain such
difference. If the goal is exceeded in an amount which qualifies for a lower
sales charge, a price adjustment is made by refunding to the purchaser the
amount of excess sales charge, if any, paid during the thirteen-month period.
Investors electing to purchase Class A shares of the Fund pursuant to a Letter
of Intent should carefully read such Letter of Intent.
 
WAIVER OF THE CONTINGENT DEFERRED SALES CHARGE--CLASS B SHARES
 
  The contingent deferred sales charge is waived under circumstances described
in the Prospectus. See "Shareholder Guide--How to Sell Your Shares--Waiver of
the Contingent Deferred Sales Charges--Class B Shares" in the Prospectus. In
connection with these waivers, the Transfer Agent will require you to submit
the supporting documentation set forth below.

<PAGE>
 
                        SHAREHOLDER INVESTMENT ACCOUNT
 
  Upon the initial purchase of shares of the Portfolio, a Shareholder
Investment Account is established for each investor under which shares are
held for the investor by the Transfer Agent. If a stock certificate is
desired, it must be requested in writing for each transaction. Certificates
are issued only for full shares and may be redeposited in the Account at any
time. There is no charge to the investor for issuance of a certificate. The
Fund makes available to the shareholders the following privileges and plans.
 
AUTOMATIC REINVESTMENT OF DIVIDENDS AND/OR DISTRIBUTIONS
 
  For the convenience of investors, all dividends and distributions are
automatically reinvested in full and fractional shares of the Portfolio. An
investor may direct the Transfer Agent in writing not less than five full
business days prior to the record date to have subsequent dividends and/or
distributions sent in cash rather than reinvested. In the case of recently
purchased shares for which registration instructions have not been received on
the record date, cash payment will be made directly to the dealer. Any
shareholder who receives a cash payment representing a dividend or
distribution may reinvest such distribution at net asset value by returning
the check or the proceeds to the Transfer Agent within 30 days after the
payment date. Such investment will be made at the net asset value next
determined after receipt of the check or proceeds by the Transfer Agent. Such
shareholder will receive credit for any contingent deferred sales charge paid
in connection with the amount of proceeds being reinvested.
 
EXCHANGE PRIVILEGE
 
  The Portfolio makes available to its shareholders the privilege of
exchanging their shares of the Portfolio for shares of certain other
Prudential Mutual Funds, including one or more specified money market funds,
subject in each case to the minimum investment requirements of such funds.
Shares of other Prudential Mutual Funds may also be exchanged for shares of
the Portfolio. All exchanges are made on the basis of relative net asset value
next determined after receipt of an order in proper form. An exchange will be
treated as a redemption and purchase for tax purposes. Shares may be exchanged
for shares of another fund only if shares of such fund may legally be sold
under applicable state laws. For retirement and group plans having a limited
menu of Prudential Mutual Funds, the Exchange Privilege is available for those
funds eligible for investment in the particular program.
 
  It is contemplated that the exchange privilege may be applicable to new
mutual funds whose shares may be distributed by the Distributor.
 
  CLASS A. Shareholders of the Portfolio may exchange their Class A shares for
Class A shares of certain other Prudential Mutual Funds, shares of Prudential
Government Securities Trust (Intermediate Term Series) and shares of the money
market funds specified below. No fee or sales load will be imposed upon the
exchange. Shareholders of money market funds who acquired such shares upon
exchange of Class A shares may use the Exchange Privilege only to acquire
Class A shares of the Prudential Mutual Funds participating in the Exchange
Privilege.
 
  The following money market funds participate in the Class A Exchange
Privilege:
 
     Prudential California Municipal Fund
      (California Money Market Series)
     Prudential Government Securities Trust
      (Money Market Series)
      (U.S. Treasury Money Market Series)
     Prudential Municipal Series Fund
      (Connecticut Money Market Series)
      (Massachusetts Money Market Series)
      (New Jersey Money Market Series)
      (New York Money Market Series)
     Prudential MoneyMart Assets
     Prudential Tax-Free Money Fund
 
  CLASS B AND CLASS C. Shareholders of the Portfolio may exchange their Class
B and Class C shares for Class B and Class C shares, respectively, of certain
other Prudential Mutual Funds and shares of Prudential Special Money Market
Fund, Inc., a money market fund. No contingent deferred sales charge will be
payable upon such exchange, but a CDSC may be payable upon the redemption of
Class B and Class C shares acquired as a result of the exchange. The
applicable sales charge will be that imposed by the fund in which shares were
initially purchased and the purchase date will be deemed to be the first day
of the month after the initial purchase, rather than the date of the exchange.
 
  Class B and Class C shares of the Portfolio may also be exchanged for shares
of Prudential Special Money Market Fund without imposition of any CDSC at the
time of exchange. Upon subsequent redemption from such money market fund or
after re-exchange
 
                                     B-19
<PAGE>
 
into the Fund, such shares will be subject to the CDSC calculated by excluding
the time such shares were held in the money market fund. In order to minimize
the period of time in which shares are subject to a contingent deferred sales
charge, shares exchanged out of the money market fund will be exchanged on the
basis of their remaining holding periods, with the longest remaining holding
periods being transferred first. In measuring the time period shares are held
in a money market fund and "tolled" for purposes of calculating the CDSC
holding period, exchanges are deemed to have been made on the last day of the
month. Thus, if shares are exchanged into the Portfolio from a money market
fund during the month (and are held in the Portfolio at the end of month), the
entire month will be included in the CDSC holding period. Conversely, if shares
are exchanged into a money market fund prior to the last day of the month (and
are held in the money market fund on the last day of the month), the entire
month will be excluded from the CDSC holding period. For purposes of
calculating the five year holding period applicable to the Class B conversion
feature, the time period during which Class B shares were held in a money
market fund will be excluded.
 
  At any time after acquiring shares of other funds participating in the Class
B or Class C exchange privilege, a shareholder may again exchange those shares
(and any reinvested dividends and distributions) for Class B or Class C shares
of the Portfolio, respectively, without subjecting such shares to any CDSC.
Shares of any fund participating in the Class B or Class C exchange privilege
that were acquired through reinvestment of dividends or distributions may be
exchanged for Class B or Class C shares of other funds, respectively, without
being subject to any CDSC.
 
  Additional details about the Exchange Privilege and prospectuses for each of
the Prudential Mutual Funds are available from the Fund's Transfer Agent,
Prudential Securities or Prusec. The Exchange Privilege may be modified,
terminated or suspended on sixty days' notice, and any fund, including the
Fund, or the Distributor, has the right to reject any exchange application
relating to such fund's shares.
 
DOLLAR COST AVERAGING
 
  Dollar cost averaging is a method of accumulating shares by investing a fixed
amount of dollars in shares at set intervals. An investor buys more shares when
the price is low and fewer shares when the price is high. The average cost per
share is lower than it would be if a constant number of shares were bought at
set intervals.
 
  Dollar cost averaging may be used, for example, to plan for retirement, to
save for a major expenditure, such as the purchase of a home, or to finance a
college education. The cost of a year's education at a four-year college today
averages around $14,000 at a private college and around $4,800 at a public
university. Assuming these costs increase at a rate of 7% a year, as has been
projected, for the freshman class of 2007, the cost of four years at a private
college could reach $163,000 and over $97,000 at a public university./1/

- ---------
  /1/Source information concerning the costs of education at public
universities is available from The College Board Annual Survey of Colleges,
1992. Information about the costs of private colleges is from the Digest of
Education Statistics, 1992; The National Center for Educational Statistics; and
the U.S. Department of Education. Average costs for private institutions
include tuition, fees, room and board.
 
  /2/The chart assumes an average rate of return of 8%. This example is for
illustrative purposes only and is not intended to reflect the performance of an
investment in shares of the Portfolio. 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.
 
AUTOMATIC SAVINGS ACCUMULATION PLAN (ASAP)
 
  Under ASAP, an investor may arrange to have a fixed amount automatically
invested in the shares of the Portfolio monthly by authorizing his or her bank
account or Prudential Securities account (including a Command Account) to be
debited to invest specified
 
                                      B-20
<PAGE>
 
dollar amounts in shares of the Fund. The investor's bank must be a member of
the Automatic Clearing House System. Stock certificates are not issued to ASAP
participants.
 
  Further information about this program and an application form can be
obtained from the Transfer Agent, Prudential Securities or Prusec.
 
SYSTEMATIC WITHDRAWAL PLAN
 
  A systematic withdrawal plan is available for shareholders through Prudential
Securities or the Transfer Agent. Such withdrawal plan provides for monthly or
quarterly checks in any amount, except as provided below, up to the value of
the shares in the shareholder's account. Withdrawals of Class B or Class C
shares may be subject to a CDSC. See "Shareholder Guide--How to Sell Your
Shares--Contingent Deferred Sales Charges" in the Prospectus.
 
  In the case of shares held through the Transfer Agent (i) a $10,000 minimum
account value applies, (ii) withdrawals may not be for less than $100 and (iii)
the shareholder must elect to have all dividends and/or distributions
automatically reinvested in additional full and fractional shares at net asset
value on shares held under this plan. See "Shareholder Investment Account--
Automatic Reinvestment of Dividends and/or Distributions."
 
  Prudential Securities and the Transfer Agent act as agents for the
shareholder in redeeming sufficient full and fractional shares to provide the
amount of the periodic withdrawal payment. The systematic withdrawal plan may
be terminated at any time, and the Distributor reserves the right to initiate a
fee of up to $5 per withdrawal, upon 30 days' written notice to the
shareholder.
 
  Withdrawal payments should not generally be considered as dividends, yield or
income. If periodic withdrawals continuously exceed reinvested dividends and
distributions, the shareholder's original investment will be correspondingly
reduced and ultimately exhausted.
 
  Furthermore, each withdrawal constitutes a redemption of shares, and any gain
or loss realized must generally be recognized for federal income tax purposes.
In addition, withdrawals made concurrently with purchases of additional shares
are inadvisable because of the applicable sales charges to (i) the purchase of
Class A shares and (ii) the withdrawal of Class B and Class C shares. Each
shareholder should consult his or her own tax adviser with regard to the tax
consequences of the plan, particularly if used in connection with a retirement
plan.
 
TAX-DEFERRED RETIREMENT PLANS
 
  Various tax-deferred retirement plans, including a 401(k) plan, self-directed
individual retirement accounts and "tax sheltered accounts" under Section
403(b)(7) of the Internal Revenue Code are available through the Distributor.
These plans are for use by both self-employed individuals and corporate
employers. These plans permit either self-direction of accounts by
participants, or a pooled account arrangement. Information regarding the
establishment of these plans, the administration, custodial fees and other
details are available from Prudential Securities or the Transfer Agent.
 
  Investors who are considering the adoption of such a plan should consult with
their own legal counsel or tax adviser with respect to the establishment and
maintenance of any such plan.
 
TAX-DEFERRED RETIREMENT ACCOUNTS
 
  INDIVIDUAL RETIREMENT ACCOUNTS. An individual retirement account (IRA)
permits the deferral of federal income tax on income earned in the account
until the earnings are withdrawn. The following chart represents a comparison
of the earnings in a personal savings account with those in an IRA, assuming a
$2,000 annual contribution, an 8% rate of return and a 39.6% federal income tax
bracket and shows how much more retirement income can accumulate within an IRA
as opposed to a taxable individual savings account.

                                NET ASSET VALUE
 
  The net asset value per share is the net worth of the Portfolio (assets,
including securities at value, minus liabilities) divided by the number of
shares outstanding. The net asset value is calculated separately for each class
of the Portfolio.
 
  Under the Investment Company Act, the Board of Directors is responsible for
determining in good faith the fair value of securities of the Fund. In
accordance with procedures adopted by the Board of Directors, the value of each
U.S. Government and corporate security of the Portfolio for which quotations
are available will be based on the valuation provided by an independent pricing
service. Pricing services consider such factors as security prices, yields,
maturities, call features, ratings and developments relating to specific
securities in arriving at securities valuations. Futures contracts are valued
daily at 4:15 P.M., New York time, at market quotations provided by the Chicago
Board of Trade.
 
  Securities for which market quotations are not readily available are valued
at fair value as determined in good faith under procedures established by the
Fund's Board of Directors. 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 if their original term
to maturity from the date of purchase was 60 days or less, or by amortizing
their value on the 61st day prior to maturity, if their original term to
maturity from the date of purchase exceeded 60 days, unless this valuation is
determined not to represent fair value by the Board of Directors.
 
  The Portfolio will compute its net asset value once daily on days that the
New York Stock Exchange is open for trading except on days on which no orders
to purchase, sell or redeem shares have been received by the Fund or days on
which changes in the value of the Fund's portfolio securities do not affect the
net asset value. The New York Stock Exchange is closed on the following
holidays; New Year's Day, Presidents' Day, Good Friday, Memorial Day,
Independence Day, Labor Day, Thanksgiving Day and Christmas Day.
 
  As long as the Portfolio declares dividends daily, the net asset value of the
Class A, Class B and Class C shares of the Portfolio will generally be the
same. It is expected, however, that the dividends will differ by approximately
the amount of the distribution-related expense differential between the
classes.
 
                          DIVIDENDS AND DISTRIBUTIONS
 
  The Portfolio declares dividends daily based on actual net investment income
determined in accordance with generally accepted accounting principles. Such
dividends will be payable monthly. The Portfolio's net capital gains, if any,
will be distributed at least annually. In determining the amount of capital
gains to be distributed, any capital loss carryforwards from prior years will
be offset against capital gains. Dividends and distributions will be paid in
additional Class A, Class B or Class C shares of the Portfolio based on net
asset value on the payment date or such other date as the Board of Directors
may determine, unless the shareholder elects in writing not less than five full
business days prior to the payment date to receive such distributions in cash.
In the event that a shareholder's shares are redeemed on a date other than the
monthly dividend payment date, the proceeds of such redemption will equal the
net asset value of the shares redeemed plus the amount of all dividends
declared through the date of redemption.
 
  The per share dividends on Class B and Class C shares will be lower than the
per share dividends on Class A shares as a result of the higher distribution
fee applicable to the Class B and Class C shares. The per share distributions
of net capital gains, if any, will be paid in the same amount for Class A,
Class B and Class C shares. See "Net Asset Value."
 
                                     TAXES
 
  GENERAL
 
  The Portfolio has elected and intends to remain qualified as a regulated
investment company under Subchapter M of the Internal Revenue Code. This
relieves the Portfolio (but not its shareholders) from paying federal income
tax on income which is distributed to shareholders, provided that it
distributes at least 90% of its net investment income and short-term capital
gains, and permits net capital gains of the Portfolio (i.e., the excess of net
long-term capital gains over net short-term capital losses) to be treated as
long-term capital gains of the shareholders, regardless of how long
shareholders have held their shares in the Portfolio.
 
  Qualification as a regulated investment company will be determined at the
level of the Portfolio and not at the level of the Fund. Accordingly, the
determination of whether the Portfolio qualifies as a regulated investment
company will be based on the activities of the Portfolio, including the
purchases and sales of securities and the income received and expenses incurred
in the Portfolio. Net capital gains of the Portfolio which are available for
distribution to shareholders will be computed by taking into account any
capital loss carryforward of such Portfolio.
 
  Qualification as a regulated investment company requires, among other things,
that (a) at least 90% of the Portfolio's annual gross income (without reduction
for losses from the sale or other disposition of securities) be derived from
interest, dividends, payments with respect to securities loans and gains from
the sale or other disposition of securities, options thereon, futures
contracts,
 
                                      B-22
<PAGE>
 
options thereon, forward contracts and foreign currencies; (b) the Portfolio
derives less than 30% of its gross income from gains (without reduction for
losses) from the sale or other disposition of securities, options thereon,
futures contracts, options thereon, forward contracts and foreign currencies
held for less than three months; and (c) the Portfolio diversifies its holdings
so that, at the end of each quarter of the taxable year, (i) at least 50% of
the market value of the Portfolio's assets is represented by cash, U.S.
Government obligations and other securities limited in respect of any one
issuer to an amount not greater than 5% of the Portfolio's assets and 10% of
the outstanding voting securities of such issuer, and (ii) not more than 25% of
the value of its assets is invested in the securities of any one issuer (other
than U.S. Government obligations).
 
  Gains or losses on sales of securities by the Portfolio will be treated as
long-term capital gains or losses if the securities have been held by it for
more than one year, except in certain cases where the Portfolio acquires a put
or writes a call thereon or makes a short sale against-the-box. Other gains or
losses on the sale of securities will be short-term capital gains or losses.
Debt securities acquired by the Portfolio may be subject to original issue
discount and market discount rules.
 
  Special rules will apply to futures contracts and options thereon in which
the Portfolio invests. See "Investment Objective and Policies." These
investments will generally constitute "Section 1256 contracts" and will be
required to be "marked to market" for federal income tax purposes at the end of
the Portfolio's taxable year; that is, treated as having been sold at market
value. Sixty percent of any gain or loss recognized on such "deemed sales" and
on actual dispositions will be treated as long-term capital gain or loss, and
the remainder will be treated as short-term capital gain or loss.
 
  The Portfolio's hedging activities may be affected by the requirement under
the Internal Revenue Code that no more than 30% of the Portfolio's income be
derived from securities, futures contracts and other instruments held for less
than three months. From time to time, this requirement may cause the Portfolio
to limit its acquisitions of futures contracts to those that will not expire
for at least three months. For example, at the present time, there is only a
limited market for futures contracts on the municipal bond index that will not
expire within three months.
 
  The Portfolio is subject to a nondeductible 4% excise tax if it does not
distribute 98% of its ordinary income on a calendar year basis and 98% of its
capital gains on an October 31 year-end basis. Each Portfolio intends to
distribute its income and capital gains in the manner necessary to avoid
imposition of the 4% excise tax. Dividends and distributions generally are
taxable to shareholders in the year in which they are received or accrued;
however, dividends declared in October, November and December payable to
shareholders of record on a specified date in October, November and December
and paid in the following January may be treated as having been paid by the
Portfolio and received by shareholders in such prior year. Under this rule, a
shareholder may be taxed in one year on dividends or distributions actually
received in January of the following year.
 
  Any loss realized on a sale, redemption or exchange of shares of the
Portfolio by a shareholder will be disallowed to the extent the shares are
replaced within a 61-day period (beginning 30 days before the disposition of
shares). Shares purchased pursuant to the reinvestment of a dividend will
constitute a replacement of shares.
 
  A shareholder who acquires shares of the Portfolio and sells or otherwise
disposes of such shares within 90 days of acquisition may not be allowed to
include certain sales charges incurred in acquiring such shares for purposes of
calculating gain or loss realized upon a sale or exchange of shares of the
Portfolio.
 
  Any dividends or distributions paid shortly after a purchase by an investor
may have the effect of reducing the per share net asset value of the investor's
shares by the per share amount of the dividends or distributions. Furthermore,
such dividends or distributions, although in effect a return of capital, are
subject to federal income taxes. Therefore, prior to purchasing shares of the
Portfolio, the investor should carefully consider the impact of dividends or
capital gains distributions which are expected to be or have been announced.
 
  Distributions may be subject to additional state and local taxes. See "Taxes,
Dividends and Distributions" in the Prospectus.
 
  If any net long-term capital gains in excess of net short-term capital losses
are retained by the Portfolio for investment, requiring federal income taxes to
be paid thereon by the Portfolio, the Portfolio will elect to treat these
capital gains as having been distributed to shareholders. As a result, these
amounts will be taxed to shareholders as long-term capital gains, and
shareholders will be able to claim their proportionate share of the federal
income taxes paid by the Portfolio on the gains as a credit against their own
federal income tax liabilities and will be entitled to increase the adjusted
tax basis of their shares in the Portfolio by the difference between their pro
rata share of such gains and their tax credit.
 
  Under federal income tax law, the Portfolio will be required to report to the
Internal Revenue Service all distributions of taxable income and capital gains
as well as gross proceeds from the redemption or exchange of shares of the
Portfolio, except in the case of certain exempt shareholders. Further, all such
distributions and proceeds from the redemption or exchange of shares may be
subject to withholding of federal income tax at the rate of 31% in the case of
nonexempt shareholders who fail to furnish the Fund with their taxpayer
identification numbers on IRS Form W-9 and with required certifications
regarding their status under the federal income tax
 
                                      B-23
<PAGE>
 
law. If the withholding provisions are applicable, any such distributions and
proceeds, whether taken in cash or reinvested in shares, will be reduced by the
amounts required to be withheld. Investors may wish to consult their tax
advisers about the applicability of the backup withholding provisions.
 
  Distributions of net investment income and net realized capital gains will be
taxable as described below, whether made in shares or in cash. Shareholders
electing to receive distributions in the form of additional shares will have a
cost basis for federal income tax purposes in each share so received equal to
the net asset value of a share of the Portfolio on the distribution date. All
distributions of taxable net investment income and net realized capital gains,
whether received in shares or cash, must be reported by each shareholder on his
or her federal income tax return.
 
  Distributions to shareholders of the Portfolio of net investment income and
of the excess of net short-term capital gains over net long-term capital losses
will be taxable to the shareholder at ordinary income rates regardless of
whether the shareholder receives such distributions in additional shares or
cash.
 
  Distributions of net capital gains (i.e., the excess of net long-term capital
gains over net short-term capital losses), if any, are taxable as long-term
capital gains regardless of how long the investor has held his or her shares.
However, if a shareholder holds shares in the Portfolio for not more than six
months, then any loss recognized on the sale of such shares will be treated as
long-term capital loss to the extent of any distribution on the shares which
was treated as long-term capital gain. Shareholders will be notified annually
by the Portfolio as to the federal tax status of distributions made by the
Portfolio.
 
                            PERFORMANCE INFORMATION
 
 
  AVERAGE ANNUAL TOTAL RETURN. The Portfolio may advertise its average annual
total return. Average annual total return is determined separately for Class A,
Class B and Class C shares. See "How the Fund Calculates Performance" in the
Prospectus.
 
  Average annual total return is computed according to the following formula:
 
                         P(1+T) to the nth power = ERV
 
Where: P = a hypothetical initial payment of $1,000.
T = average annual total return.
n = number of years.
ERV = Ending Redeemable Value of a hypothetical $1,000 payment made at the
         beginning of the 1, 5 or 10 year periods (or fractional portion
         thereof) at the end of the 1, 5 or 10 year periods.
 
  Average annual return takes into account any applicable initial or contingent
deferred sales charges but does not take into account any federal or state
income taxes that may be payable upon redemption.
 
  The average annual total return for Class A shares of the Portfolio for the
one year and since inception periods ended December 31, 1993 was 3.70% and
8.37%, respectively. Without expense subsidies and the management fee waiver,
the average annual total return for these periods would have been 3.70% and
8.14%, respectively. The average annual total return with respect to the Class
B shares of the Portfolio for the one year and since inception periods ended
December 31, 1993 was 3.38% and 4.45%. As of December 31, 1993, there were no
Class C shares outstanding for the Portfolio.
 
  AGGREGATE TOTAL RETURN. The Portfolio may also advertise its aggregate total
return. Aggregate total return is determined separately for Class A, Class B
and Class C shares. See "How the Fund Calculates Performance" in the
Prospectus.
 
  Aggregate total return represents the cumulative change in the value of an
investment in the Portfolio and is computed by the following formula:
                                    ERV - P
                                       P
  Where: P = a hypothetical initial payment of $1,000.
     ERV = Ending Redeemable Value of a hypothetical $1,000 payment made at
         the beginning of the 1, 5 or 10 year periods (or fractional portion
         thereof) at the end of the 1, 5, or 10 year periods.
 
  Aggregate total return does not take into account any federal or state income
taxes that may be payable upon redemption or any applicable initial or
contingent deferred sales charges.
 
  The aggregate total return for Class A shares of the Portfolio for the one
year and since inception periods ended December 31, 1993 was 7.14%,and 46.46%,
respectively. The aggregate total return for Class B shares of the Portfolio
for the one year and since inception periods ended December 31, 1993 was 6.38%
and 6.72%, respectively. As of December 31, 1993, there were no Class C shares
outstanding for the Portfolio.
 
  YIELD. The Portfolio may from time to time advertise its yield as calculated
over a 30-day period. Yield is calculated separately for Class A, Class B and
Class C shares. This yield will be computed by dividing the Portfolio's net
investment income per share earned
 
                                      B-24
<PAGE>
 
during this 30-day period by the maximum offering price per share on the last
day of this period. Yield is calculated according to the following formula:
                                           
                                a - b  
                     YIELD = 2[(----- +1) to the 6th power -1]
                                 cd
 
                                       
  Where: a = dividends and interest earned during the period.
     b = expenses accrued for the period (net of reimbursements).
     c = the average daily number of shares outstanding during the period
        that were entitled to receive dividends.
     d = the maximum offering price per share on the last day of the period.
 
  Yield fluctuates and an annualized yield quotation is not a representation by
the Fund as to what an investment in the Portfolio will actually yield for any
given period.
 
  The yield for the 30-day period ended December 31, 1993 for the Portfolio's
Class A and Class B shares was 3.98% and 3.36%, respectively. As of December
31, 1993, there were no Class C shares outstanding for the Portfolio.
 
  Income earned on the Portfolio could be subject to the federal alternative
minimum tax. The above information is for illustrative purposes only and is not
intended to imply actual performance.

 PRUDENTIAL STRUCTURED MATURITY FUND
 INCOME PORTFOLIO
 Notes to Financial Statements
   Prudential Structured Maturity Fund (the ``Fund''), is registered under the
Investment Company Act of 1940, as a diversified, open-end management investment
company. The Fund consists of two portfolios--the Income Portfolio (the
``Portfolio'') and the Municipal Income Portfolio. The Municipal Income
Portfolio has not yet begun operations. The Fund was incorporated in Maryland on
June 8, 1988 and had no operations until July 1989 when 8,613 shares of the
Portfolio's common stock was sold for $100,000 to Prudential Mutual Fund
Management, Inc. (``PMF''). Investment operations commenced on September 1,
1989. The Portfolio's investment objective is high current income consistent
with the preservation of principal. The ability of issuers of debt securities
held by the Portfolio to meet their obligations may be affected by economic
developments in a specific industry or region.

Note 1. Accounting            The following is a summary
Policies                      of significant accounting poli-
                              cies followed by the Portfolio in the preparation
of its financial statements.
Securities Valuation: The Board of Directors has authorized the use of an
independent pricing service to determine valuations of U.S. Government and
corporate obligations. The pricing service considers such factors as security
prices, yields, maturities, call features, ratings and developments relating to
specific securities in arriving at securities valuations. When market quotations
are not readily available, a security is valued by appraisal at its fair value
as determined in good faith under procedures established under the general
supervision and responsibility of the Board of Directors.
   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.
   In connection with transactions in repurchase agreements, the Portfolio's
custodian takes possession of the underlying collateral securities, the value of
which at least equals the principal amount of the repurchase transaction,
including accrued interest. To the extent that any repurchase transaction
exceeds one business day, the value of the collateral is marked-to-market on a
daily basis to ensure the adequacy of the collateral. If the seller defaults and
the value of the collateral declines or if bankruptcy proceedings are commenced
with respect to the seller of the security, realization of the collateral by the
Fund may be delayed or limited.
Securities Transactions and 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.
   Net investment income (other than distribution fees) and unrealized and
realized 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.
Federal Income Taxes: It is the Portfolio's policy to continue to meet the
requirements of the Internal Revenue Code applicable to regulated investment
companies and to distribute all of its taxable net income and capital gains, if
any, to its shareholders. Therefore, no federal income tax provision is
required.
Dividends and Distributions: The Portfolio declares daily and pays monthly
dividends of net investment income. Distributions of net capital gains, if any,
are made at least annually. Dividends and distributions are recorded on the
ex-dividend date.
   Income and capital gain distributions are determined in accordance with
income tax regulations which may differ from generally accepted accounting
principles.
Deferred Organization Expenses: Approximately $160,000 of expenses were incurred
in connection with the organization and initial registration of the Portfolio.
These expenses have been deferred and are being amortized over the period of
benefit not to exceed 60 months from the date of commencement of investment
operations.

Note 2. Agreements            The Fund has a management
                              agreement with PMF. Pursuant to this agreement,
PMF has responsibility for all investment advisory services and supervises the
subadviser's performance of such services. PMF has entered into a subadvisory
agreement with The Prudential Investment Corporation (``PIC''); PIC furnishes
investment advisory services in connection with the management of the Fund. PMF
pays for the cost of the subadviser's services, the compensation of officers and
employees 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 PMF is computed daily and payable monthly, at an
annual rate of .40 of 1% of the average daily net assets of the Portfolio.

                                     B-32

   The Fund has distribution agreements with Prudential Mutual Fund
Distributors, Inc. (``PMFD''), which acts as distributor of the Class A shares
of the Fund, and with Prudential Securities Incorporated (``PSI''), which acts
as distributor of the Class B shares of the Fund (collectively the
``Distributors''). To reimburse the Distributors for their expenses incurred in
distributing and servicing the Fund's Class A and B shares, the Fund, pursuant
to plans of distribution, pays the Distributors a reimbursement, accrued daily
and payable monthly.
   Pursuant to the Class A Plan, the Portfolio reimburses PMFD for its
distribution-related expenses with respect to Class A shares at an annual rate
of .10 of 1% of the average daily net assets of the Class A shares. PMFD pays
various broker-dealers, including PSI and Pruco Securities Corporation
(``Prusec''), affiliated broker-dealers, for account servicing fees and other
expenses incurred by such broker-dealers.
   Pursuant to the Class B Plan, the Portfolio reimburses PSI for its
distribution-related expenses with respect to Class B shares at an annual rate
of up to 1% of the average daily net assets of the Class B shares. Such expenses
under the Class B Plan were .85 of 1% of the average daily net assets of the
Class B shares for the year ended December 31, 1993.
   The Class B distribution expenses include commission credits for payment of
commissions and account servicing fees to financial advisers and an allocation
for overhead and other distribution-related expenses, interest and/or carrying
charges, the cost of printing and mailing prospectuses to potential investors
and of advertising incurred in connection with the distribution of shares.
   The Distributors recover the distribution expenses and service fees incurred
through the receipt of reimbursement payments from the Portfolio under the plans
and the receipt of initial sales charges (Class A only) and contingent deferred
sales charges (Class B only) from shareholders.
   PMFD has advised the Portfolio that it has received approximately $669,100 in
front-end sales charges resulting from sales of Class A shares during the year
ended December 31, 1993. From these fees, PMFD paid such sales charges to
dealers (PSI and Prusec) which in turn paid commissions to salespersons.
   With respect to the Class B Plan, at any given time, the amount of expenses
incurred by PSI in distributing the Portfolio's shares and not recovered through
the imposition of contingent deferred sales charges in connection with certain
redemptions of shares may exceed the total reimbursement made by the Portfolio
pursuant to the Class B Plan. PSI advised the Portfolio that for the year ended
December 31, 1993, it received approximately $86,000 in contingent deferred
sales charges imposed upon certain redemptions by investors. PSI, as
distributor, has also advised the Portfolio that at December 31, 1993, the
amount of distribution expenses incurred by PSI and not yet reimbursed by the
Fund or recovered through contingent deferred sales charges approximated
$2,318,100. This amount may be recovered through future payments under the Class
B Plan or contingent deferred sales charges.
   In the event of termination or noncontinuation of the Class B Plan, the
Portfolio would not be contractually obligated to pay PSI, as distributor, for
any expenses not previously reimbursed under the Class B Plan or recovered
through contingent deferred sales charges.
   PMFD is a wholly-owned subsidiary of PMF; PSI, PMF and PIC are indirect,
wholly-owned subsidiaries of The Prudential Insurance Company of America.

Note 3. Other                 Prudential Mutual Fund Ser-
Transactions                  vices, Inc. (``PMFS''), a 
with Affiliates               wholly-owned subsidiary of 
                              PMF, serves as the Portfolio's transfer agent.
During the year ended December 31, 1993, the Portfolio incurred fees of
approximately $169,000 for the services of PMFS. As of December 31, 1993,
approximately $20,000 of such fees were due to PMFS. Transfer agent fees and
expenses in the Statement of Operations also include certain out-of-pocket
expenses paid to non-affiliates.

Note 4. Portfolio             Purchases and sales of port-
Securities                    folio securities, excluding 
                              short-term investments, for the year ended
December 31, 1993 were $361,710,920 and $245,081,744, respectively.
   The federal income tax basis of the Portfolio's investments at December 31,
1993 was $239,784,112 and accordingly, net unrealized appreciation for federal
income tax purposes was $416,546 (gross unrealized appreciation--$2,259,467;
gross unrealized depreciation-- $1,842,921).
   The Portfolio elected to treat approximately $249,000 of net capital losses
incurred in the two month period ended December 31, 1993 as having occurred in
the following year.

                              Class A and Class B shares. Class A shares are
sold with a front-end sales charge of up to 3.25%. Class B shares are sold with
a contingent deferred sales charge which declines from 3% to zero depending on
the period of time the shares are held. Both classes of shares have equal rights
as to earnings, assets and voting privileges except that each class bears
different distribution expenses and has exclusive voting rights with respect to
its distribution plan. Class B shares commenced operations on December 9, 1992.
   There are 500 million shares of $.01 par value common stock, divided into two
classes, designated Class A and Class B common stock, each of which consists of

                          INDEPENDENT AUDITORS' REPORT

The Shareholders and Board of Directors of
Prudential Structured Maturity Fund, Income Portfolio

   We have audited the accompanying statement of assets and liabilities,
including the portfolio of investments, of Prudential Structured Maturity Fund,
Income Portfolio, as of December 31, 1993, the related statements of operations
for the year then ended and of changes in net assets for each of the years in
the two year period then ended, and the financial highlights for each of the
periods in the four year period then ended and for the period September 1, 1989
(commencement of investment operations) to December 31, 1989. These financial
statements and the financial highlights are the responsibility of the Fund's
management. Our responsibility is to express an opinion on these financial
statements and the financial highlights based on our audits.

   We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of the securities owned at
December 31, 1993 by correspondence with the custodian and brokers; where
replies were not received from brokers, we performed other auditing procedures.
An audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

   In our opinion, such financial statements and financial highlights present
fairly, in all material respects, the financial position of Prudential
Structured Maturity Fund, Income Portfolio, as of December 31, 1993, the results
of its operations, the changes in its net assets and the financial highlights
for the respective stated periods in conformity with generally accepted
accounting principles.
