RISK/RETURN SUMMARY
- --------------------------------------------------------------------------------

This section highlights key information about PRUDENTIAL STOCK INDEX FUND, which
we refer to as "the Fund." The Fund is a series of Prudential Index Series Fund
(the Company). Additional information follows this summary.

INVESTMENT OBJECTIVE AND PRINCIPAL STRATEGIES

Our investment objective is to seek to PROVIDE INVESTMENT RESULTS THAT
CORRESPOND TO THE PRICE AND YIELD PERFORMANCE OF THE STANDARD & POOR'S 500
COMPOSITE STOCK PRICE INDEX (S&P 500 INDEX). The Fund intends to invest at least
80% of its total assets in securities included in the S&P 500 Index in the same
proportions as those of the Index. The Fund tries to achieve a correlation
between its performance and the performance of the S&P 500 Index of at least
0.95, without taking into account expenses. The Fund may invest in foreign
securities denominated in U.S. dollars and may use derivatives.

      While we make every effort to achieve our objective, we can't guarantee
success.

PRINCIPAL RISKS

Although we try to invest wisely, all investments involve risk. The Fund's
performance will not precisely correspond to the performance of the S&P 500
Index. Potential tracking differences, brokerage and other costs and other Fund
expenses may cause the Fund's return to be lower than that of the S&P 500 Index.
Since the Fund invests primarily in common stock, there is the risk that the
price of a particular stock we own could go down, or the value of the equity
markets or a sector of them could go down. Stock markets are volatile.
Generally, the stock prices of large and medium-sized companies are more stable
than the stock prices of small companies.

      Since we invest in foreign securities, there are different risks than if
we invested only in U.S. stocks. Foreign markets are often more volatile than
U.S. markets and are generally not subject to regulatory requirements comparable
to those in the U.S.

      Some of our investment strategies may present above-average risks. The
Fund may use risk management techniques to try to preserve assets or enhance
return. Derivatives may not fully offset the underlying positions and this could
result in losses to the Fund that would not otherwise have occurred.

- --------------------------------------------------------------------------------
DID YOU KNOW...

The Fund employs a "passively managed"--or index--investment approach. We hold
the same mix of stocks as is held in the S&P 500 Index. The S&P 500 Index is an
unmanaged, market-weighted index of 500 stocks selected by Standard & Poor's
Corporation (S&P) on the basis of their market size, liquidity and industry
group representation. The S&P 500 Index is composed of stocks representing more
than 70% of the total market value of all publicly traded U.S. common stocks and
is widely regarded as representative of the performance of the U.S. stock
market as a whole.

RISK/RETURN SUMMARY
- --------------------------------------------------------------------------------

      Like any mutual fund, an investment in the Fund could lose value and you
could lose money. For more detailed information about the risks associated with
the Fund, see "How the Fund Invests-Investment Risks."

      An investment in the Fund is not a bank deposit and is not insured or
guaranteed by the Federal Deposit Insurance Corporation or any other government
agency.

EVALUATING PERFORMANCE

A number of factors--including risk--affect how the Fund performs. The following
bar chart shows the Fund's performance for each full calendar year of operation.
The bar chart and table below demonstrate the risk of investing in the Fund and
how the Fund's average annual returns compare with those of a broad measure of
market performance. Past performance does not mean that the Fund will achieve
similar results in the future.

expenses, but represents an investment in the same fund. Class A, Class Z and
Class I shares are available only to a limited group of investors. Before the
date of this Prospectus, only Class Z and Class I shares were offered. For more

EXAMPLE

This example will help you compare the fees and expenses of the Fund's different
share classes and the cost of investing in the Fund with the cost of investing
in other mutual funds.

      The example assumes that you invest $10,000 in the Fund for the time
periods indicated and then sell all of your shares at the end of those periods.
The example also assumes that your investment has a 5% return each year and that
the Fund's operating expenses remain the same. After the first year, the example
does not take into account the Manager's agreement to subsidize expenses and the
Distributor's agreement to reduce distribution and service (12b-1) fees for
Class A shares. Although your actual costs may be higher or lower, based on
these assumptions, your costs would be:

HOW THE FUND INVESTS
- --------------------------------------------------------------------------------

INVESTMENT OBJECTIVE AND POLICIES

The Fund's investment objective is to seek to PROVIDE INVESTMENT RESULTS THAT
CORRESPOND TO THE PRICE AND YIELD PERFORMANCE OF THE S&P 500 INDEX. While we
make every effort to achieve our objective, we can't guarantee success.

- --------------------------------------------------------------------------------

                                    [To Come]

- --------------------------------------------------------------------------------

      The Fund intends to invest at least 80% of its total assets in securities
included in the S&P 500 Index in the same proportions as those of the Index. The
Fund tries to achieve a correlation between its performance and the performance
of the S&P 500 Index of at least 0.95, without taking into account expenses. The
Fund may invest the balance of its assets in (1) equity-related securities, (2)
U.S. government obligations, (3) put and call options on securities and stock
indexes, and (4) futures contracts on stock indexes and options.

      In addition to common stocks, equity-related securities include
nonconvertible preferred stocks, convertible securities, American Depositary
Receipts (ADRs), warrants and rights that can be exercised to obtain stock;
investments in various types of business ventures, including partnerships and
joint ventures; real estate investment trusts (REITs) and similar securities.
Convertible securities are securities--like bonds, corporate notes and preferred
stocks--that we can convert into the company's common stock or some other equity
security.

      When deciding whether to sell securities, we follow the S&P 500 Index.
When a security is sold from the Index, we sell it too.

      The investment adviser will try to minimize the difference between the
investment results of the Fund and that of the S&P 500 Index. Trading will be
monitored regularly. In addition to potential trading differences, brokerage,
other transaction costs and other Fund expenses may cause the Fund's return to
be lower than the return of the S&P 500 Index.

Risks." The Statement of Additional Information--which we refer to as the
SAI--contains additional information about the Fund and the Company. To obtain a
copy, see the back cover page of this prospectus.

      The Fund's investment objective is a fundamental policy that cannot be
changed without shareholder approval. The Board can change investment policies
that are not fundamental.

OTHER INVESTMENTS

In addition to the principal strategies, we may also make the following
investments to try to increase the Fund's returns or protect its assets if
market conditions warrant.

FOREIGN SECURITIES

We may invest in FOREIGN EQUITY SECURITIES DENOMINATED IN U.S. DOLLARS. For
these purposes, we do not consider ADRs and other similar receipts or shares to
be foreign securities.

U.S. GOVERNMENT SECURITIES

The Fund may invest in securities issued or guaranteed by the U.S. Treasury or
by an agency or instrumentality of the U.S. government. Not all U.S. government
securities are backed by the full faith and credit of the United States. Some
are supported only by the credit of the issuing agency.

TEMPORARY DEFENSIVE INVESTMENTS

In response to adverse market, economic or political conditions, we may
temporarily invest up to 100% of the Fund's assets in MONEY MARKET INSTRUMENTS,
including commercial paper of domestic and foreign corporations, certificates of
deposit, bankers' acceptances, time deposits of domestic and foreign banks
and short-term obligations issued or guaranteed by the U.S. government and its
agencies. Investing heavily in these securities limits our ability to achieve
capital appreciation, but can help to preserve the Fund's assets when the equity
markets are volatile.

      The Fund also may temporarily hold cash or invest in high-quality foreign
or domestic money market instruments pending investment of proceeds from new
sales of the Fund shares or to meet ordinary daily cash needs. This is subject
to the policy of normally investing at least 80% of the Fund's assets in
securities included in the S&P 500 Index.

- --------------------------------------------------------------------------------
HOW THE FUND INVESTS
- --------------------------------------------------------------------------------

REPURCHASE AGREEMENTS

The Fund may also use REPURCHASE AGREEMENTS, where a party agrees to sell a
security to the Fund and then repurchase it at an agreed-upon price at a stated
time. This creates a fixed return for the Fund and is in effect a loan by the
Fund.

DERIVATIVE STRATEGIES

We may use various derivative strategies to try to improve the Fund's returns or
protect its assets. We cannot guarantee that these strategies will work, that
the instruments necessary to implement these strategies will be available, or
that the Fund will not lose money. Derivatives--such as futures on securities
indexes, options on securities and securities indexes, and options on
futures--involve costs and can be volatile. With derivatives, the investment
adviser tries to predict whether the underlying investment--a security, market
index, currency, interest rate or some other benchmark--will go up or down at
some future date. We may use derivatives to try to reduce risk or to increase
return consistent with the Fund's overall investment objective. The investment
adviser will consider other factors (such as cost) in deciding whether to employ
any particular strategy or use any particular instrument. Any derivatives we use
may not match the Fund's underlying holdings.

OPTIONS

The Fund may purchase and sell put and call options on securities and securities
indexes traded on U.S. or foreign securities exchanges or on the
over-the-counter market. An option is the right to buy or sell securities in
exchange for a premium. The Fund will sell only covered options.

FUTURES CONTRACTS AND RELATED OPTIONS

The Fund may purchase and sell stock index futures contracts and related options
on stock index futures. A futures contract is an agreement to buy or sell a set
quantity of an underlying product at a future date, or to make or receive a cash
payment based on the value of a securities index.

      For more information about these strategies, see the SAI, "Description of
the Funds, Their Investments and Risks--Risk Management and Return Enhancement
Strategies."

ADDITIONAL STRATEGIES

The Fund also follows certain policies when it BORROWS MONEY (the Fund can
borrow up to 20% of the value of its total assets); LENDS ITS SECURITIES to
others

(the Fund can lend up to 30% of the value of its total assets, including
collateral received in the transaction); and HOLDS ILLIQUID SECURITIES (the Fund
may hold up to 15% of its net assets in illiquid securities, including
securities with legal or contractual restrictions, those without a readily
available market, and repurchase agreements with maturities longer than seven
days). The Fund is subject to certain investment restrictions that are
fundamental policies, which means they cannot be changed without shareholder
approval. For more information about these restrictions, see the SAI.

INVESTMENT RISKS

As noted, all investments involve risk, and investing in the Fund is no
exception. This chart outlines the key risks and potential rewards of the Fund's
principal investments and certain other investments the Fund may make. See, too,

HOW THE FUND IS MANAGED
- --------------------------------------------------------------------------------

BOARD OF TRUSTEES

The Board of Trustees oversees the actions of the Manager, Investment Adviser
and Distributor and decides on general policies. The Board also oversees the
Company's officers, who conduct and supervise the daily business operations of
the Fund.

MANAGER

PRUDENTIAL INVESTMENTS FUND MANAGEMENT LLC (PIFM)
GATEWAY CENTER THREE, 100 MULBERRY STREET
NEWARK, NJ 07102-4077

      Under a management agreement with the Fund, PIFM manages the Fund's
investment operations and administers its business affairs. For the fiscal year
ended September 30, 1998, the Fund paid PIFM management fees of .30 of 1% of the
Fund's average net assets.

      As of August 31, 1999, PIFM served as the Manager to all of the Prudential
mutual funds, and as Manager or administrator to closed-end investment
companies, with aggregate assets of approximately $ billion.

INVESTMENT ADVISER

The Prudential Investment Corporation, called Prudential Investments, is the
Fund's investment adviser. Its address is Prudential Plaza, 751 Broad Street,
Newark, NJ 07102. PIFM has responsibility for all investment advisory services,
supervises Prudential Investments and reimburses Prudential Investments for its
reasonable costs and expenses.

DISTRIBUTOR

Prudential Investment Management Services LLC (PIMS) distributes the Fund's
shares under a Distribution Agreement with the Fund. The Fund has Distribution
and Service Plans under Rule 12b-1 of the Investment Company Act. Under the
Plans and the Distribution Agreement, PIMS pays the expenses of distributing the
Fund's Class A, B, C, Z and I shares and provides certain shareholder support
services. The Fund pays distribution and other fees to PIMS as compensation for
its services for each class of shares other than Class Z and Class I. These
fees--known as 12b-1 fees--are shown in the "Fees and Expenses" tables.

HOW THE FUND IS MANAGED
- --------------------------------------------------------------------------------

YEAR 2000 READINESS DISCLOSURE

The services provided to the Fund and the shareholders by the Manager, the
Distributor, the Transfer Agent and the Custodian depend on the smooth
functioning of their computer systems and those of outside service providers.
Many computer software systems in use today cannot distinguish the year 2000
from the year 1900 because of the way dates are encoded and calculated. Such an
event could have a negative impact on handling securities trades, payments of
interest and dividends, pricing and account services. Although, at this time,
there can be no assurance that there will be no adverse impact on the Fund, the
Manager, the Distributor, the Transfer Agent and the Custodian have advised the
Fund that they have been actively working on necessary changes to their computer
systems to prepare for the year 2000. The Fund and its Board receive, and have
received since early 1998, satisfactory quarterly reports from the principal
service providers as to their preparations for year 2000 readiness, although
there can be no assurance that the service providers (or other securities market
participants) will successfully complete the necessary changes in a timely
manner or that there will be no adverse impact on the Fund. Moreover, the Fund
at this time has not considered retaining alternative service providers or
directly undertaken efforts to achieve year 2000 readiness, the latter of which
would involve substantial expenses without an assurance of success.

      Additionally, issuers of securities generally, as well as those purchased
by the Fund, may confront year 2000 compliance issues which, if material and not
resolved, could have an adverse impact on securities markets and/or a specific
issuer's performance and could result in a decline in the value of the
securities held by the Fund.

FUND DISTRIBUTIONS AND TAX ISSUES
- --------------------------------------------------------------------------------

Investors who buy shares of the Fund should be aware of some important tax
issues. For example, the Fund distributes DIVIDENDS of ordinary income and any
realized net CAPITAL GAINS to shareholders. These distributions are subject to
taxes, unless you hold your shares in a 401(k) plan, an Individual Retirement
Account (IRA), or some other qualified tax-deferred plan or account.

      Also, if you sell shares of the Fund for a profit, you may have to pay
capital gains taxes on the amount of your profit, again unless you hold your
shares in a qualified tax-deferred plan or account.

      The following briefly discusses some of the important federal tax issues
you should be aware of, but is not meant to be tax advice. For tax advice,
please speak with your tax adviser.

DISTRIBUTIONS

      The Fund declares daily and distributes DIVIDENDS of any net investment
income to shareholders once a year. For example, if the Fund owns Acme Corp.
stock and the stock pays a dividend, the Fund will pay out a portion of this
dividend to its shareholders, assuming the Fund's income is more than its costs
and expenses. The dividends you receive from the Fund will be taxed as ordinary
income whether or not they are reinvested in the Fund.

      The Fund also distributes realized net CAPITAL GAINS to
shareholders--typically once a year--which are generated when the Fund sells its
assets for a profit. For example, if the Fund bought Acme Corp. stock for a
total of $1,000 and more than one year later sold the shares for a total of
$1,500, the Fund has net long-term capital gains of $500, which it will pass on
to shareholders (assuming the Fund's total gains are greater than any losses it
may have). Capital gains are taxed differently depending on how long the Fund
holds the security--if a security is held more than one year before it is sold,
LONG-TERM capital gains are taxed at the rate of 20%, but if the security is
held one year or less, SHORT-TERM capital gains are taxed at ordinary income
rates of up to 39.6%. Different rates apply to corporate shareholders.

      For your convenience, Fund distributions of dividends and capital gains
are AUTOMATICALLY REINVESTED in the Fund without any sales charge. If you ask us
to pay the distributions in cash, we will send you a check if your account is
with the Transfer Agent. Otherwise, if your account is with a broker, you will
receive a credit to your account. Either way, the distributions may be subject
to taxes, unless your shares are held in a qualified tax-deferred plan or
account. For more information about automatic reinvestment and other shareholder
services, see "Step 4: Additional Shareholder Services" in the next section.

FUND DISTRIBUTIONS AND TAX ISSUES
- --------------------------------------------------------------------------------

TAX ISSUES

FORM 1099

Every year, you will receive a Form 1099, which reports the amount of dividends
and capital gains we distributed to you during the prior year. If you own shares
of the Fund as part of a qualified tax-deferred plan or account, your taxes are
deferred, so you will not receive a Form 1099. However, you will receive a Form
1099 when you take any distributions from your qualified tax-deferred plan or
account.

      Fund distributions are generally taxable to you in the calendar year they
are received, except when we declare certain dividends in the fourth quarter and
actually pay them in January of the following year. In such cases, the dividends
are treated as if they were paid on December 31 of the prior year. Corporate
shareholders are eligible for the 70% dividends-received deduction for certain
dividends.

WITHHOLDING TAXES

If federal tax law requires you to provide the Fund with your tax identification
number and certifications as to your tax status, and you fail to do this, we
will withhold and pay to the U.S. Treasury 31% of your distributions and sale
proceeds. If you are subject to backup withholding, we will withhold and pay to
the U.S. Treasury 31% of your distributions. Dividends of net investment income
and short-term capital gains paid to a nonresident foreign shareholder generally
will be subject to a U.S. withholding tax of 30%. This rate may be lower,
depending on any tax treaty the U.S. may have with the shareholder's country.

IF YOU PURCHASE JUST BEFORE RECORD DATE

If you buy shares of the Fund just before the record date (the date that
determines who receives the distribution), that distribution will be paid to
you. As explained above, the distribution may be subject to income or capital
gains taxes. You may think you've done well since you bought shares one day and
soon thereafter received a distribution. That is not so because when dividends
are paid out, the value of each share of the Fund decreases by the amount of the
dividend and the market changes (if any) to reflect the payout. The distribution
you receive makes up for the decrease in share value. However, the timing of
your purchase does mean that part of your investment came back to you as taxable

FUND DISTRIBUTIONS AND TAX ISSUES
- --------------------------------------------------------------------------------

QUALIFIED RETIREMENT PLANS

Retirement plans and accounts allow you to defer paying taxes on investment
income and capital gains. Contributions to these plans may also be tax
deductible, although distributions from these plans generally are taxable. In
the case of Roth IRA accounts, contributions are not tax deductible, but
distributions from the plan may be tax free. Please contact your financial
adviser for information on a variety of Prudential mutual funds that are
suitable for retirement plans offered by Prudential.

IF YOU SELL OR EXCHANGE YOUR SHARES

If you sell any shares of the Fund for a profit, you have REALIZED A CAPITAL
GAIN, which is subject to tax, unless you hold shares in a qualified
tax-deferred plan or account. The amount of tax you pay depends on how long you
owned your shares. If you sell shares of the Fund for a loss, you may have a
capital loss, which you may use to offset certain capital gains you have.

      Exchanging your shares of the Fund for the shares of another Prudential
mutual fund is considered a sale for tax purposes. In other words, it's a
"taxable event." Therefore, if the shares you exchanged have increased in value
since you purchased them, you have capital gains, which are subject to the taxes
described above.

- --------------------------------------------------------------------------------

                                     (offset against gain)

- --------------------------------------------------------------------------------

      Any gain or loss you may have from selling or exchanging Fund shares will
not be reported on Form 1099; however, proceeds from the sale or exchange will
be reported on Form 1099-B. Therefore, unless you hold your shares in a
qualified tax-deferred plan or account, you or your financial adviser should
keep track of the dates on which you buy and sell--or exchange--Fund shares, as
well as the amount of any gain or loss on each transaction. For tax advice,
please see your tax adviser.

AUTOMATIC CONVERSION OF CLASS B SHARES

We have obtained a legal opinion that the conversion of Class B shares into
Class A shares--which happens automatically approximately seven years after
purchase--is not a "taxable event" because it does not involve an actual sale of
your Class B shares. This opinion, however, is not binding on the Internal
Revenue Service. For more information about the automatic conversion of Class B
shares, see "Class B Shares Convert to Class A Shares After Approximately Seven
Years" in the next section.

HOW TO BUY, SELL AND
- --------------------------------------------------------------------------------
EXCHANGE SHARES OF THE FUND
- --------------------------------------------------------------------------------

HOW TO BUY SHARES

STEP 1: OPEN AN ACCOUNT

If you don't have an account with us or a securities firm that is permitted to
buy or sell shares of the Fund for you, call Prudential Mutual Fund Services LLC
(PMFS) at (800) 225-1852 or contact:

PRUDENTIAL MUTUAL FUND SERVICES LLC
ATTN: INVESTMENT SERVICES
P.O. BOX 15020
NEW BRUNSWICK, NJ 08906-5020

      To purchase by wire, call the number above to obtain an application. After
PMFS receives your completed application, you will receive an account number.
For additional information about purchasing shares of the Fund, see the back
cover page of this prospectus. We have the right to reject any purchase order
(including an exchange into the Fund) or suspend or modify the Fund's sale of
its shares.

STEP 2: CHOOSE A SHARE CLASS

Individual investors can choose among Class A, Class B, Class C, Class Z and
Class I shares of the Fund, although Class A, Class Z and Class I shares are
available only to a limited group of investors.

     Multiple share classes let you choose a cost structure that better meets
your needs. With Class A shares, you pay no sales charge and the operating
expenses each year are lower than the expenses of Class B and Class C shares,
but the operating expenses are higher than those of Class Z and Class I shares.
With Class B shares, you only pay a sales charge if you sell your shares within
six years (that is why it is called a Contingent Deferred Sales Charge or CDSC),
but the operating expenses each year are higher than those of the Class A, Class
Z and Class I shares. With Class C shares, you pay a 1% front-end sales charge
and a 1% CDSC if you sell within 18 months of purchase, but the operating
expenses are also higher than the expenses for Class A, Class Z and Class I
shares.

      When choosing a share class, you should consider the following:

      o     The amount of your investment
      o     The length of time you expect to hold the shares and the impact of
            the varying distribution fees
      o     The different sales charges that may apply to a share class--Class
            B's CDSC vs. Class C's low front-end sales charge and low CDSC

      o     Whether you qualify to purchase Class A, Class Z or Class I shares.

      See "How to Sell Your Shares" for a description of the impact of CDSCs.

HOW TO BUY, SELL AND
- --------------------------------------------------------------------------------
EXCHANGE SHARES OF THE FUND
- --------------------------------------------------------------------------------

QUALIFYING FOR CLASS A SHARES

You can purchase Class A shares if you invest at least $1 million or if you
exchange into the Fund from another Fund.

IF YOU INVEST MORE THAN $1 MILLION, YOU MAY QUALIFY TO BUY CLASS Z OR CLASS I
SHARES.

      To satisfy this purchase amount, you can:

      o     Invest with an eligible group of related investors
      o     Buy the Class A shares of two or more Prudential mutual funds at the
            same time
      o     Use your RIGHTS OF ACCUMULATION, which allow you to combine the
            value of Prudential mutual fund shares you already own with the
            value of the shares you are purchasing for purposes of determining
            the applicable sales charge (note: you must notify the Transfer
            Agent if you qualify for Rights of Accumulation)
      o     Sign a LETTER OF INTENT, stating in writing that you or a group of
            related investors will purchase a certain amount of shares in the
            Fund and other Prudential mutual funds within 13 months.

BENEFIT PLANS. Certain group retirement and savings plans may purchase Class A
shares, provided that they meet the required minimum for amount of assets,
average account balance or number of eligible employees. For more information
about these requirements, call Prudential at (800) 353-2847.

MUTUAL FUND PROGRAMS. You may purchase Class A shares if you are an investor in
certain programs sponsored by broker-dealers, investment advisers and financial
planners who have agreements with Prudential Investments Advisory Group relating
to:

      o     Mutual fund "wrap" or asset allocation programs, where the sponsor
            places Fund trades and charges its clients a management, consulting
            or other fee for its services.
      o     Mutual fund "supermarket" programs where the sponsor links its
            customers' accounts to a master account in the sponsor's name and
            the sponsor charges a fee for its services.

      Broker-dealers, investment advisers or financial planners sponsoring these
mutual fund programs may offer their clients more than one class of shares in
the Fund in connection with different pricing options for their programs.
Investors should consider carefully any separate transaction and other fees
charged by these programs in connection with investing in each available share
class before selecting a share class.

OTHER TYPES OF INVESTORS. Certain officers, employees or agents of Prudential
and its affiliates, Prudential mutual funds, the subadvisers of the Prudential
mutual funds and clients of brokers that have entered into a selected dealer
agreement with the Distributor also may purchase Class A shares subject to the
previously stated minimum. To qualify you must notify the Transfer Agent or your
broker at the time of purchase. For more information, see the SAI, "Purchase,
Redemption and Pricing of Fund Shares--Class A Shares."

WAIVING CLASS C'S INITIAL SALES CHARGE

BENEFIT PLANS. Certain group retirement plans may purchase Class C shares
without the initial sales charge. For more information, call Prudential at (800)
353-2847.

PRUDENTIAL RETIREMENT PLANS. The initial sales charge will be waived for
purchases of Class C shares by both qualified and nonqualified retirement and
deferred compensation plans participating in a PruArray Plan and other plans if
Prudential also provides administrative or recordkeeping services.

INVESTMENT OF REDEMPTION PROCEEDS FROM OTHER INVESTMENT COMPANIES. The initial
sales charge will be waived for purchases of Class C shares if the purchase is
made with money from the redemption of shares of any unaffiliated investment
company, as long as the shares were not held in an account at Prudential
Securities Incorporated or one of its affiliates. These purchases must be made
within 60 days of the redemption. To qualify for this waiver, you must do one of
the following:

      o     Purchase your shares through an account at Prudential Securities
      o     Purchase your shares through an ADVANTAGE Account or an Investor
            Account with Pruco Securities Corporation
      o     Purchase your shares through another broker.

      This waiver is not available to investors who purchase shares directly
from the Transfer Agent. If you are entitled to the waiver, you must notify
either the Transfer Agent or your broker. The Transfer Agent may require any
supporting documents it considers appropriate.

QUALIFYING FOR CLASS Z SHARES

Certain group retirement plans may purchase Class Z shares, provided that they
meet the required minimum amount of assets, average account balance or

number of eligible employees. For more information about these requirements,
call Prudential at (800) 353-2847.

MUTUAL FUND PROGRAMS. Class Z shares can also be purchased by participants in
any fee-based program or trust program sponsored by Prudential or an affiliate
which includes the Fund as an available option. Class Z shares also can be
purchased by investors in certain programs sponsored by broker-dealers,
investment advisers and financial planners who have agreements with Prudential
Investments Advisory Group relating to:

      o     Mutual fund "wrap" or asset allocation programs, where the sponsor
            places Fund trades, links its clients' accounts to a master account
            in the sponsor's name and charges a management, consulting or other
            fee for its services
      o     Mutual fund "supermarket" programs, where the sponsor links its
            customers' accounts to a master account in the sponsor's name and
            the sponsor charges a fee for its services.

      Broker-dealers, investment advisers or financial planners sponsoring these
mutual fund programs may offer their clients more than one class of shares in
the Fund in connection with different pricing options for their programs.
Investors should consider carefully any separate transaction and other fees
charged by these programs in connection with investing in each available share
class before selecting a share class.

OTHER TYPES OF INVESTORS. Class Z shares also can be purchased by any of the
following:

      o     Certain participants in the MEDLEY Program (group variable annuity
            contracts) sponsored by Prudential for whom Class Z shares of the
            Prudential mutual funds are an available option
      o     Current and former Directors/Trustees of the Prudential mutual funds
            (including the Company)
      o     Prudential with an investment of $10 million or more.

      In connection with the sale of shares, the Manager, the Distributor or one
of their affiliates may pay brokers, financial advisers and other persons a
commission of up to 4% of the purchase price for Class B shares, up to 2% of the
purchase price for Class C shares and a finder's fee for Class Z and Class I
shares from their own resources based on a percentage of the net asset value of
shares sold or otherwise.

- --------------------------------------------------------------------------------
EXCHANGE SHARES OF THE FUND
- --------------------------------------------------------------------------------

QUALIFYING FOR CLASS I SHARES

Certain group retirement plans may purchase Class I shares provided that they
meet the required minimum amount of assets, average account balance and certain
other conditions. All shares must be held in a single omnibus account. For
more information about these requirements, call Prudential at (800) 353-2847.

CLASS B SHARES CONVERT TO CLASS A SHARES AFTER APPROXIMATELY SEVEN YEARS

If you buy Class B shares and hold them for approximately seven years, we will
automatically convert them into Class A shares without charge. At that time, we
will also convert any Class B shares that you received with reinvested dividends
and other distributions. Since the 12b-1 fees for Class A shares are lower than
for Class B shares, converting to Class A shares lowers your Fund expenses.

      When we do the conversion, you will get fewer Class A shares than the
number of converted Class B shares if the price of the Class A shares is higher
than the price of Class B shares. The total dollar value will be the same, so
you will not have lost any money by getting fewer Class A shares. We do the
conversions quarterly, not on the anniversary date of your purchase. For more
information, see the SAI, "Purchase, Redemption and Pricing of Fund
Shares--Conversion Feature--Class B Shares."

STEP 3: UNDERSTANDING THE PRICE YOU'LL PAY

The price you pay for each share of the Fund is based on the share value. The
share value of a mutual fund--known as the NET ASSET VALUE or NAV--is determined
by a simple calculation: it's the total value of the Fund (assets minus
liabilities) divided by the total number of shares outstanding. For example, if
the value of the investments held by Fund XYZ (minus its liabilities) is $1,000
and there are 100 shares of Fund XYZ owned by shareholders, the price of one
share of the fund--or the NAV--is $10 ($1,000 divided by 100). Portfolio
securities are valued based upon market quotations or, if not readily available,
at fair value as determined in good faith under procedures established by the
Fund's Board. Most national newspapers report the NAVs of most mutual funds,
which allows investors to check the price of mutual funds daily.



- --------------------------------------------------------------------------------
                                                                              23

<PAGE>


HOW TO BUY, SELL AND
- --------------------------------------------------------------------------------
EXCHANGE SHARES OF THE FUND
- --------------------------------------------------------------------------------

   We determine the NAV of our shares once each business day at 4:15 p.m. New
York Time on days that the New York Stock Exchange is open for trading. We do
not determine the NAV on days when we have not received any orders to purchase,
sell or exchange Fund shares, or when changes in the value of the Fund's
portfolio do not materially affect the NAV.

- --------------------------------------------------------------------------------
MUTUAL FUND SHARES

The NAV of mutual fund shares changes every day because the value of a fund's
portfolio changes constantly. For example, if Fund XYZ holds ACME Corp. stock in
its portfolio and the price of ACME stock goes up while the value of the fund's
other holdings remains the same and expenses don't change, the NAV of Fund XYZ
will increase.
- --------------------------------------------------------------------------------

WHAT PRICE WILL YOU PAY FOR SHARES OF THE FUND?

For Class C shares, you'll pay the public offering price, which is the NAV next
determined after we receive your order to purchase, plus an initial sales charge
(unless you're entitled to a waiver). For Class A, Class B, Class Z and Class I
shares, you will pay the NAV next determined after we receive your order to
purchase (remember, there are no up-front sales charges for these share
classes). Your broker may charge a separate or additional fee for purchases of
shares.

STEP 4: ADDITIONAL SHAREHOLDER SERVICES

As a Fund shareholder, you can take advantage of the following services and
privileges:

AUTOMATIC REINVESTMENT. As we explained in the "Fund Distributions and Tax
Issues" section, the Fund pays out--or distributes--its net investment income
and capital gains to all shareholders. For your convenience, we will
automatically reinvest your distributions in the Fund at NAV, without any sales
charge. If you want your distributions paid in cash, you can indicate this
preference on your application, notify your broker or notify the Transfer Agent
in writing (at the address below) at least five business days before the date we
determine who receives dividends.

AUTOMATIC INVESTMENT PLAN. You can make regular purchases of the Fund for as
little as $50 by having the funds automatically withdrawn from your bank or
brokerage account at specified intervals.

RETIREMENT PLAN SERVICES. Prudential offers a wide variety of retirement plans
for individuals and institutions, including large and small businesses. For
information on IRAs, including Roth IRAs, or SEP IRAs for a one-person business,
please contact your financial adviser. If you are interested in opening a 401(k)
or other company-sponsored retirement plan (SIMPLES, SEP plans, Keoghs, 403(b)
plans, pension and profit-sharing plans), your financial adviser will help you
determine which retirement plan best meets your needs. Complete instructions
about how to establish and maintain your plan and how to open accounts for you
and your employees will be included in the retirement plan kit you receive in
the mail.

THE PRUTECTOR PROGRAM. Optional group term life insurance--which protects the
value of your Prudential mutual fund investment for your beneficiaries against
market declines--is available to investors who purchase their shares through
Prudential. This insurance is subject to various restrictions and charges and is
not available in all states.

SYSTEMATIC WITHDRAWAL PLAN. A systematic withdrawal plan is available that will
provide you with monthly or quarterly checks. Remember, the sale of Class B and
Class C shares may be subject to a CDSC.

REPORTS TO SHAREHOLDERS. Every year we will send you an annual report (along
with an updated prospectus) and a semi-annual report, which contain important
financial information about the Fund. To reduce Fund expenses, we

will send one annual shareholder report, one semi-annual shareholder report and
one annual prospectus per household, unless you instruct us or your broker
otherwise.

HOW TO SELL YOUR SHARES

You can sell your shares of the Fund for cash (in the form of a check) at any
time, subject to certain restrictions.

      When you sell shares of the Fund--also known as redeeming your shares--the
price you will receive will be the NAV next determined after the Transfer Agent,
the Distributor or your broker receives your order to sell. If your broker holds
your shares, your broker must receive your order to sell by 4:15 p.m. New York
Time to process the sale on that day. Otherwise contact:

PRUDENTIAL MUTUAL FUND SERVICES LLC
ATTN: REDEMPTION SERVICES
P.O. BOX 15010
NEW BRUNSWICK, NJ 08906-5010

      Generally, we will pay you for the shares that you sell within seven days
after the Transfer Agent, the Distributor or your broker receives your sell
order. If you hold shares through a broker, payment will be credited to your
account. If you are selling shares you recently purchased with a check, we may
delay sending you the proceeds until your check clears, which can take up to 10
days from the purchase date. You can avoid delay if you purchase by wire,
certified check or cashier's check. Your broker may charge you a separate or
additional fee for sales of shares.

RESTRICTIONS ON SALES

There are certain times when you may not be able to sell shares of the Fund, or
when we may delay paying you the proceeds from a sale. This may happen during
unusual market conditions or emergencies when the Fund can't determine the value
of its assets or sell its holdings. For more information, see the SAI,
"Purchase, Redemption and Pricing of Fund Shares--Sale of Shares."

      If you are selling more than $100,000 of shares, you want the check sent
to someone or some place that is not in our records, or you are a business or a
trust and you hold your shares directly with the Transfer Agent, you will need
to have the signature on your sell order guaranteed by a financial institution.

If you sell Class B shares within six years of purchase or Class C shares within
18 months of purchase, you will have to pay a CDSC. To keep the CDSC as low as
possible, we will sell amounts representing shares in the following order:

      o     Amounts representing shares you purchased with reinvested dividends
            and distributions
      o     Amounts representing the increase in NAV above the total amount of
            payments for shares made during the past six years for Class B
            shares and 18 months for Class C shares
      o     Amounts representing the cost of shares held beyond the CDSC period
            (six years for Class B shares and 18 months for Class C shares).

      Since shares that fall into any of the categories listed above are not
subject to the CDSC, selling them first helps you to avoid--or at least
minimize--the CDSC.

      Having sold the exempt shares first, if there are any remaining shares
that are subject to the CDSC, we will apply the CDSC to amounts representing the
cost of shares held for the longest period of time within the applicable CDSC
period.

      As we noted before in the "Share Class Comparison" chart, the CDSC for
Class B shares is 5% in the first year, 4% in the second, 3% in the third, 2% in
the fourth and 1% in the fifth and sixth years. The rate decreases on the first
day of the month following the anniversary date of your purchase, not on the
anniversary date itself. The CDSC is 1% for Class C shares--which is applied to
shares sold within 18 months of purchase. For both Class B and Class C shares,
the CDSC is calculated based on the lesser of the original purchase price or the
redemption proceeds. For purposes of determining how long you've held your
shares, all purchases during the month are grouped together and considered to
have been made on the last day of the month.

      The holding period for purposes of determining the applicable CDSC will be
calculated from the first day of the month after initial purchase, excluding any
time shares were held in a money market fund.

WAIVER OF THE CDSC--CLASS B SHARES

The CDSC will be waived if the Class B shares are sold:

      o     After a shareholder is deceased or disabled (or, in the case of a
            trust account, the death or disability of the grantor). This waiver
            applies to individual shareholders, as well as shares owned in joint
            tenancy (with rights of survivorship), provided the shares were
            purchased before the death or disability
      o     To provide for certain distributions--made without IRS penalty--from
            a tax-deferred retirement plan, IRA or Section 403(b) custodial
            account
      o     On certain sales from a Systematic Withdrawal Plan

      For more information on the above and other waivers, see the SAI,
"Purchase, Redemption and Pricing of Fund Shares--Waiver of Contingent Deferred
Sales Charge--Class B Shares."

WAIVER OF THE CDSC--CLASS C SHARES

BENEFIT PLANS. The CDSC will be waived for redemptions by certain group
retirement plans for which Prudential or brokers not affiliated with Prudential
provide administrative or recordkeeping services. The CDSC also will be waived
for certain redemptions by benefit plans sponsored by Prudential and its
affiliates. For more information, call Prudential at (800) 353-2847.

REDEMPTION IN KIND

If the sales of Fund shares you make during any 90-day period reach the lesser
of $250,000 or 1% of the value of the Fund's net assets, we can then give you
securities from the Fund's portfolio instead of cash. If you want to sell the
securities for cash, you would have to pay the costs charged by a broker.

90-DAY REPURCHASE PRIVILEGE

After you redeem your shares, you have a 90-day period during which you may
reinvest any of the redemption proceeds in shares of the same Fund without
paying an initial sales charge. Also, if you paid a CDSC when you redeemed your
shares, we will credit your new account with the appropriate number of shares to
reflect the amount of the CDSC you paid. In order to take advantage of this
one-time privilege, you must notify the Transfer Agent or your broker at the
time of the repurchase. See the SAI, "Purchase, Redemption and Pricing of Fund
Shares--Sale of Shares."

RETIREMENT PLANS

To sell shares and receive a distribution from your retirement account, call
your broker or the Transfer Agent for a distribution request form. There are
special distribution and income tax withholding requirements for distributions
from retirement plans and you must submit a withholding form with your request
to avoid delay. If your retirement plan account is held for you by your employer
or plan trustee, you must arrange for the distribution request to be signed and
sent by the plan administrator or trustee. For additional information, see the
SAI.

HOW TO EXCHANGE YOUR SHARES

You can exchange your shares of the Fund for shares of the same class in certain
other Prudential mutual funds--including certain money market funds--if you
satisfy the minimum investment requirements. For example, you can exchange Class
A shares of the Fund for Class A shares of another Prudential mutual fund, but
you can't exchange Class A shares for Class B, Class C or Class Z shares. Class
I shares, though, can be exchanged for Class Z shares of other Prudential mutual
funds. Class B and Class C shares may not be exchanged into money market funds
other than Prudential Special Money Market Fund, Inc. After an exchange, at
redemption, the CDSC will be calculated from the first day of the month after
initial purchase, excluding any time shares were held in a money market fund. We
may change the terms of the exchange privilege after giving you 60 days' notice.

      If you hold shares through a broker, you must exchange shares through your
broker. Otherwise contact:

PRUDENTIAL MUTUAL FUND SERVICES LLC
ATTN: EXCHANGE PROCESSING
P.O. BOX 15010
NEW BRUNSWICK, NJ 08906-5010

      There is no sales charge for such exchanges. However, if you exchange--and
then sell--Class B shares within approximately six years of your original
purchase, or Class C shares within 18 months of your original purchase, you must
still pay the applicable CDSC. If you have exchanged Class B or Class C shares
into a money market fund, the time you hold the shares in the money market
account will not be counted in calculating the required holding periods for CDSC
liability.

- --------------------------------------------------------------------------------
EXCHANGE SHARES OF THE FUND
- --------------------------------------------------------------------------------

      Remember, as we explained in the section entitled "Fund Distributions and
Tax Issues--If You Sell or Exchange Your Shares," exchanging shares is
considered a sale for tax purposes. Therefore, if the shares you exchange are
worth more than you paid for them, you may have to pay capital gains tax. For
additional information about exchanging shares, see the SAI, "Shareholder
Investment Account--Exchange Privilege."

      If you own Class B or Class C shares and qualify to purchase Class A
shares, we will automatically exchange your Class B or Class C shares which are
not subject to a CDSC for Class A shares. We make such exchanges on a quarterly
basis if you qualify for this exchange privilege. We have obtained a legal
opinion that this exchange is not a "taxable event" for federal income tax
purposes. This opinion is not binding on the IRS.

FREQUENT TRADING

Frequent trading of Fund shares in response to short-term fluctuations in the
market--also known as "market timing"--may make it very difficult to manage the
Fund's investments. When market timing occurs, the Fund may have to sell
portfolio securities to have the cash necessary to redeem the market timer's
shares. This can happen at a time when it is not advantageous to sell any
securities, so the Fund's performance may be hurt. When large dollar amounts are
involved, market timing can also make it difficult to use long-term investment
strategies because we cannot predict how much cash the Fund will have to invest.
When, in our opinion, such activity would have a disruptive effect on portfolio
management, the Fund reserves the right to refuse purchase orders and exchanges
into the Fund by any person, group or commonly controlled account. The Fund may
notify a market timer of rejection of an exchange or purchase order after the
day the order is placed. If the Fund allows a market timer to trade Fund shares,
it may require the market timer to enter into a written agreement to follow
certain procedures and limitations.

RISK/RETURN SUMMARY
- --------------------------------------------------------------------------------

This prospectus provides information about four of the five series of PRUDENTIAL
INDEX SERIES FUND, which we refer to as "the Company." Those four series are
PRUDENTIAL BOND MARKET INDEX FUND, PRUDENTIAL EUROPE INDEX FUND, PRUDENTIAL
PACIFIC INDEX FUND and PRUDENTIAL SMALL-CAP INDEX FUND (each referred to as a
"Fund" and collectively as "the Funds"). To obtain information about the fifth
series, Prudential Stock Index Fund, see the back cover page of this prospectus.
While the four Funds have some common attributes, such as many of their
investment policies, each focuses on a different index. Therefore, some sections
of this prospectus deal with each Fund separately, while other sections address
all four Funds at the same time. Additional information follows this summary.

INVESTMENT OBJECTIVES AND PRINCIPAL STRATEGIES

     Each Fund's investment objective is to seek to provide investment results
     that correspond to the performance of the applicable index. This means we
     seek investments whose price or total return will increase over time. Each
     Fund normally invests at least 80% of its total assets in equity-related
     securities of a broad-based index, except for Bond Market Index Fund, which
     invests in fixed income securities represented in a broad bound index.

o     PRUDENTIAL BOND MARKET INDEX FUND seeks to provide investment results that
      correspond to the total return performance of a broad-based index of
      fixed-income securities, currently the Lehman Brothers Aggregate Bond
      index.

o     PRUDENTIAL EUROPE INDEX FUND seeks to provide investment results that
      correspond to the price and yield performance of a broad-based index of
      securities of European issuers, currently the Morgan Stanley Capital
      International Europe Index.

o     PRUDENTIAL PACIFIC INDEX FUND seeks to provide investment results that
      correspond to the price and yield

- --------------------------------------------------------------------------------
DID YOU KNOW...

Each Fund employs a "passively managed"--or index--investment approach by
holding the same mix of stocks as is held in the applicable Index. Each Fund
uses a "sampling" technique. Using sophisticated computer programs, the Funds
select securities that will recreate their target indexes in terms of industry
weightings, market capitalization and other characteristics. For instance, if
20% of the Lehman Brothers Aggregate Bond Index were made up of corporate bonds,
the Bond Market Index Fund would invest about 20% of its assets in corporate
bonds that have similar characteristics as a group to those in that Index.

RISK/RETURN SUMMARY

      performance of a broad-based index of securities of issuers in the Pacific
      region, currently the Morgan Stanley Capital International Pacific Free
      Index.

o     PRUDENTIAL SMALL-CAP INDEX FUND seeks to provide investment results that
      correspond to the price and yield performance of a broad-based index of
      small cap stocks, currently the Standard & Poor's 600 Small Capitalization
      Stock Index (S&P 600 Index).

      Each Fund intends that at least 80% of its total assets will be invested
in securities included in the applicable index. Each Fund attempts to achieve a
correlation between its performance and the performance of the applicable index
of at least 0.95, without taking into account expenses. Each Fund may invest in
foreign securities and may use derivatives. Each Fund sells securities when they
are no longer in the applicable index.

      While we make every effort to achieve our objective, we can't guarantee
success.

PRINCIPAL RISKS

Although we try to invest wisely, all investments involve risk. The Funds'
performance will not precisely correspond to the performance of the index whose
performance each Fund seeks to replicate. Potential tracking differences,
brokerage and other costs and other Fund expenses may cause a Fund's return to
be lower than that of the applicable index.

      Since Prudential Bond Market Index Fund invests primarily in fixed income
securities, there are interest rate risks, income risk, credit risk and
prepayment risk. Interest rate risk is the chance that bond prices overall will
decline over short or even long periods due to rising interest rates. Interest
rate risk should be least for shorter-term bonds, and greatest for longer-term
bonds. Income risk is the chance that falling interest rates will cause the
Fund's income to decline. Income risk is generally higher for short-term bonds,
and lower for long-term bonds. Credit risk is the chance that a bond issuer will
fail to pay interest and principal in a timely manner, reducing the Fund's
return. Prepayment risk is the chance that during periods of falling interest
rates, a mortgage-backed bond issuer will repay a higher-yielding bond before
its maturity date. Forced to reinvest the unanticipated proceeds at lower rates,
the Fund would experience a decline in income and lose the opportunity for
additional price appreciation associated with falling rates.

      Since the Prudential Europe Index Fund, Prudential Pacific Index Fund and
Prudential Small-Cap Index Fund invest primarily in common stock, there is the
risk that the price of a particular stock we own could go down, or the value of
the equity markets or a sector of them could go down. Stock markets are
volatile. Generally, the stock prices of small-sized companies are less stable
than the stock prices of large- and medium-sized companies.

      Since we invest in foreign securities, there are different risks than if
we invested only in U.S. stocks. Foreign markets are often more volatile than
U.S.

markets and are generally not subject to regulatory requirements comparable to
those in the U.S.

      Some of our investment strategies may present above-average risks. A Fund
may use risk management techniques to try to preserve assets or enhance return.
Derivatives may not fully offset the underlying positions and this could result
in losses to the Fund that would not otherwise have occurred.

      Like any mutual fund, an investment in a Fund could lose value and you
could lose money. For more detailed information about the risks associated with
the Fund, see "How the Funds Invest-Investment Risks."

      An investment in a Fund is not a bank deposit and is not insured or
guaranteed by the Federal Deposit Insurance Corporation or any other government
agency.

EVALUATING PERFORMANCE

A number of factors--including risk--affect how each Fund performs. The
following bar chart shows each Fund's performance for each full calendar year of
operation. The bar chart and table below demonstrate the risk of investing in
the Fund and how the Fund's average annual returns compare with those of a broad
measure of market performance. Past performance does not mean that the Fund will
achieve similar results in the future.

EXAMPLE

This example will help you compare the fees and expenses of the Funds
and the cost of investing in a Fund with the cost of investing
in other mutual funds.

      The example assumes that you invest $10,000 in a Fund for the time
periods indicated and then sell all of your shares at the end of those periods.
The example also assumes that your investment has a 5% return each year and that
the Fund's operating expenses remain the same. After the first year, the example
does not take into account the Manager's agreement to subsidize expenses.
Although your actual costs may be higher or lower, based on these assumptions,

INVESTMENT OBJECTIVES AND POLICIES

Each Fund's investment objective is to seek to PROVIDE INVESTMENT RESULTS THAT
CORRESPOND TO THE PERFORMANCE OF THE APPLICABLE INDEX. While we make every
effort to achieve our objective, we can't guarantee success.

PRUDENTIAL BOND MARKET INDEX FUND

Prudential Bond Market Index Fund seeks to provide investment results that
correspond to the total return performance of a broad-based index of
fixed-income securities. The Prudential Bond Market Index Fund currently uses
the Lehman Brothers Aggregate Index. The Lehman Brothers Aggregate Index is an
unmanaged index that measures the total return (capital change plus income)
provided by a universe of fixed-income securities, weighted by market value.

      To achieve its investment objective, Prudential Bond Market Index Fund
will purchase securities that as a group reflect the performance of the Lehman
Brothers Aggregate Index. The Fund intends to hold a representative sample of
the securities that reflect the three major classes of fixed-income investments
in the Lehman Brothers Aggregate Index: U.S. Treasury and government agency
securities, investment-grade corporate debt obligations and mortgage-backed
securities. The securities included in the Index must be U.S. dollar-denominated
and investment-grade, and have a fixed rate coupon, a remaining maturity or
average life of at least one year and generally have an outstanding market value
of at least $100 million. In addition, from time to time adjustments may be made
in the holdings of the Fund due to factors which may include changes in the
composition of the Lehman Brothers Aggregate Index. As of June 30, 1999, U.S.
Treasury and agency securities comprised   % and   %, respectively, of the
Index's total market value, corporate bonds comprised   %, asset-backed
securities comprised % and mortgage-backed securities comprised   %.

PRUDENTIAL EUROPE INDEX FUND

Prudential Europe Index Fund seeks to provide investment results that correspond
to the price and yield performance of a broad-based index of securities of
European issuers. The Prudential Europe Index Fund currently uses the
MSCI-Europe Index. The MSCI-Europe Index is an unmanaged, diversified,
capitalization weighted index currently consisting of the equity securities of
592 companies located in 15 developed European countries. These countries are:
Austria, Belgium, Denmark, Finland, France, Germany, Ireland, Italy,
Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United
Kingdom. The Fund is neither sponsored by nor affiliated with Morgan Stanley &
Co. Incorporated.

      To achieve its investment objective, Prudential Europe Index Fund will
purchase the equity securities that as a group reflect the price and yield
performance of the MSCI-Europe Index. The Fund intends to invest in a
representative sample of the stocks included in the MSCI-Europe Index in
approximately the same proportions as they are represented in that index. In
addition, from time to time adjustments may be made in the holdings of the Fund
due to factors which may include changes in the composition of the MSCI-Europe
Index. The United Kingdom, Germany and France dominate the MSCI-Europe Index,
with %, % and %, respectively, of the market capitalization of the Index as of
June 30, 1999.

PRUDENTIAL PACIFIC INDEX FUND

Prudential Pacific Index Fund seeks to provide investment results that
correspond to the price and yield performance of a broad-based index of
securities of issuers in the Pacific region. The Prudential Pacific Index Fund
currently uses the MSCI-Pacific Free Index. The MSCI-Pacific Free Index is an
unmanaged, diversified, capitalization weighted index currently consisting of
508 equity securities listed on the stock exchanges of Australia, Japan, Hong
Kong, New Zealand and Singapore. The Fund is neither sponsored by nor affiliated
with Morgan Stanley & Co. Incorporated.

      To achieve its investment objective, Prudential Pacific Index Fund will
purchase the equity securities that as a group reflect the price and yield
performance of the MSCI-Pacific Free Index. The Fund intends to invest in a
representative sample of the equity securities included in the MSCI-Pacific Free
Index in approximately the same proportions as they are represented in the
MSCI-Pacific Free Index. In addition, from time to time adjustments may be made
in the holdings of the Fund due to factors which may include changes in the
composition of the MSCI-Pacific Free Index. The MSCI-Pacific Free Index is
dominated by the Japanese stock market, which represented   % of the market
capitalization of the Index as of June 30, 1999.

PRUDENTIAL SMALL-CAP INDEX FUND

Prudential Small-Cap Index Fund seeks to provide investment results that
correspond to the price and yield performance of a broad-based index of
small-cap stocks. The Prudential Small-Cap Index Fund currently uses the S&P 600
Index. The S&P 600 Index is an unmanaged, market-value weighted index (stock
price times the number of shares outstanding) of 600 smaller company U.S. common
stocks that cover all industry sectors. Inclusion in the S&P 600 Index in no way
implies an opinion by Standard & Poor's Corporation (S&P) as to a stock's
attractiveness as an investment. The S&P 600 Index currently measures the
performance of selected U.S. stock with a market value of no greater than $
million (as of June 30, 1999).

HOW THE FUNDS INVEST
- --------------------------------------------------------------------------------

      To achieve its investment objective, Prudential Small-Cap Index Fund will
purchase equity securities that as a group reflect the price and yield
performance of the S&P 600 Index. The Fund intends to purchase a representative
sample of the 600 stocks included in the S&P 600 Index in approximately the same
proportions as they are represented in the S&P 600 Index. In addition, from time
to time adjustments may be made in the holdings of the Fund due to factors which
may include changes in the composition of the S&P 600 Index or receipt of
distributions of securities of companies spun off from S&P 600 companies.

INVESTMENT POLICIES APPLICABLE TO EACH FUND

The Funds are each expected to invest in over 250 stocks (or bonds for the
Prudential Bond Market Index Fund). Stocks are selected for inclusion in each
applicable Fund's portfolio based on country, market capitalization, industry
weightings and fundamental characteristics such as return variability, earnings
valuation and yield. Each Fund's portfolio is constructed to have aggregate
investment characteristics similar to those of its respective index. In order to
parallel the performance of its respective index, Prudential Europe Index Fund
and Prudential Pacific Index Fund will invest in each country in approximately
the same percentage as the country's weight in the index.

      The Funds may not hold all of the issues that comprise their respective
indexes because of the costs involved and the illiquidity of many of the

- --------------------------------------------------------------------------------
HOW THE FUNDS INVEST
- --------------------------------------------------------------------------------

securities. Instead, each Fund will attempt to hold a representative sample of
the securities in its respective index, which will be selected utilizing a
statistical technique known as "sampling" or "portfolio optimization." Under
this technique, each stock is considered for inclusion in the portfolio based on
its contribution to certain country, capitalization, industry and fundamental
investment characteristics. Each applicable Fund's portfolio is constructed so
that, in the aggregate, the country, capitalization, industry and fundamental
investment characteristics resemble those of its respective index. Over time,
portfolio composition is altered (or "rebalanced") to reflect changes in the
characteristics of the indices.

      Due to the use of this sampling technique, the Funds' portfolios are not
expected to track their benchmark indices with the same degree of accuracy as
large capitalization domestic index funds. Each Fund will attempt to achieve a
correlation between its performance and that of its respective index of at least
0.95, without taking into account expenses. A correlation of 1.00 would indicate
perfect correlation, which would be achieved when a Fund's net asset value,
including the value of its dividends and capital gains distributions, increases
or decreases in exact proportion to changes in its respective index. The
investment adviser will, of course, attempt to minimize any tracking
differential (that is, the statistical measure of the difference between the
investment results of a Fund and that of its respective index). However, in
addition to potential tracking differences, brokerage and other transaction
costs, as well as other expenses, may cause a Fund's return to be lower than the
return of its respective index. Consequently, there can be no assurance as to
how closely a Fund's performance will correspond to the performance of its
respective index.

      The Funds intend to remain fully invested, to the extent practicable, in a
pool of securities which will approximate the investment characteristics of
their respective indexes.

      When deciding whether to sell securities, we follow the applicable index.
When a security is sold from the index, we sell it too.

EQUITY AND EQUITY-RELATED SECURITIES

Each Fund other than Prudential Bond Market Index Fund invests primarily in
equity securities, and the value of these Funds' investments will go up and down
with the performance of the stocks in the applicable index.

      In addition to common stocks, equity-related securities include
nonconvertible preferred stocks, convertible securities, American Depositary
Receipts (ADRs), warrants and rights that can be exercised to obtain stock;
investments in various types of business ventures, including partnerships and

joint ventures; real estate investment trusts (REITs) and similar securities.
Convertible securities are securities--like bonds, corporate notes and preferred
stocks--that we can convert into the company's common stock or some other equity
security.

FOREIGN SECURITIES

Prudential Europe Index Fund and Prudential Pacific Index Fund invest primarily
in equity securities of foreign companies. For these purposes, we do not
consider ADRs and other similar receipts or shares to be foreign securities.

FIXED-INCOME OBLIGATIONS

Prudential Bond Market Index Fund invests primarily in fixed-income securities
including U.S. Treasury obligations and securities issued or guaranteed by U.S.
government agencies and instrumentalities, investment-grade corporate debt
obligations and mortgage-backed securities. Not all U.S. government securities
are backed by the full faith and credit of the United States. Some are supported
only by the credit of the issuing agency. The Fund may invest in debt securities
rated investment grade (BBB/Baa or above).

MONEY MARKET INSTRUMENTS

The Funds also may temporarily hold cash or invest in high-quality foreign or
domestic money market instruments pending investment of proceeds from new sales
of the Fund shares or to meet ordinary daily cash needs subject to the policy of
normally investing at least 80% of the Fund's assets in securities included in
the applicable index.

contains additional information about the Fund and the Company. To obtain a
copy, see the back cover page of this prospectus.

      Each Fund's investment objective can be changed by the Board without
shareholder approval. The Board also can change investment policies that are not
fundamental.

OTHER INVESTMENTS

In addition to the principal strategies, we may also make the following
investments to try to increase a Fund's returns or protect its assets if
market conditions warrant.

REPURCHASE AGREEMENTS

A Fund may also use REPURCHASE AGREEMENTS, where a party agrees to sell a
security to the Fund and then repurchase it at an agreed-upon price at a stated
time. This creates a fixed return for the Fund and is in effect a loan by the
Fund.

DOLLAR ROLLS

Prudential Bond Market Index Fund may use dollar rolls as part of its investment
strategy. When the Fund enters into a dollar roll, the Fund sells securities to
be delivered in the current month and repurchases substantially similar (some
type and coupon) securities to be delivered on a specified future date by the
same party. The Fund is paid the difference between the current sales price and
the forward price for the future purchase and the interest earned on the cash
proceeds of the initial sale.

DERIVATIVE STRATEGIES

We may use various derivative strategies to try to improve a Fund's returns or
protect its assets. We cannot guarantee that these strategies will work, that
the instruments necessary to implement these strategies will be available, or
that a Fund will not lose money. Derivatives--such as futures on equity or debt
securities or indexes, options on securities, securities indexes or currencies,
and options on futures--involve costs and can be volatile. With derivatives, the
investment adviser tries to predict whether the underlying investment--a
security, market index, currency, interest rate or some other benchmark--will go
up or down at some future date. We may use derivatives to try to reduce risk or
to increase return consistent with a Fund's overall investment objective. The
investment adviser will consider other factors (such as cost) in deciding
whether to employ any particular strategy or use any particular instrument. Any
derivatives we use may not match the Fund's underlying holdings.

OPTIONS

The Funds may purchase and sell put and call options on securities and
securities indexes traded on U.S. or foreign securities exchanges on NASDAQ or
in the over-the-counter market. Prudential Europe Index Fund and Prudential
Pacific Index Fund also may purchase and sell, put and call options on
currencies. An option is the right to buy or sell securities in exchange for a
premium. The Fund will sell only covered options.

FUTURES CONTRACTS AND RELATED OPTIONS
FOREIGN CURRENCY AND FORWARD CONTRACTS

Each Fund may purchase and sell futures contracts and related options on
securities indexes. A futures contract is an agreement to buy or sell a set
quantity of an underlying product at a future date, or to make or receive a cash
payment based on the value of a securities index. Prudential Europe Index Fund
and Prudential Pacific Index Fund may also enter into foreign currency forward
contracts to protect the value of its assets against future changes in the level
of foreign exchange rates. A foreign currency forward contract is an obligation
to buy or sell a given currency on a future date at a set price.

      For more information about these strategies, see the SAI, "Description of
the Funds, Their Investments and Risks--Risk Management and Return Enhancement
Strategies."

ADDITIONAL STRATEGIES

Each Fund also follows certain policies when it BORROWS MONEY (each Fund can
borrow up to 20% of the value of its total assets); LENDS ITS SECURITIES to
others (each Fund can lend up to 30% of the value of its total assets, including
collateral received in the transaction); and HOLDS ILLIQUID SECURITIES (each
Fund may hold up to 15% of its net assets in illiquid securities, including
securities with legal or contractual restrictions, those without a readily
available market, and repurchase agreements with maturities longer than seven
days). The Funds are subject to certain investment restrictions that are
fundamental policies, which means they cannot be changed without shareholder
approval. For more information about these restrictions, see the SAI.

INVESTMENT RISKS

As noted, all investments involve risk, and investing in a Fund is no exception.
This chart outlines the key risks and potential rewards of the Fund's principal
investments and certain other investments the Fund may make. See, too,

Distribution Agreement, PIMS pays the expenses of distributing each Fund's Class
Z shares and provides certain shareholder support services.

YEAR 2000 READINESS DISCLOSURE

The services provided to the Funds and the shareholders by the Manager, the
Distributor, the Transfer Agent and the Custodian depend on the smooth
functioning of their computer systems and those of outside service providers.
Many computer software systems in use today cannot distinguish the year 2000
from the year 1900 because of the way dates are encoded and calculated. Such an
event could have a negative impact on handling securities trades, payments of
interest and dividends, pricing and account services. Although, at this time,
there can be no assurance that there will be no adverse impact on the Manager,
the Distributor, the Transfer Agent and the Custodian have advised the Funds
that they have been actively working on necessary changes to their computer
systems to prepare for the year 2000. The Company's Board receives, and has
received since early 1998, satisfactory quarterly reports from the principal
service providers as to their preparations for year 2000 readiness, although
there can be no assurance that the service providers (or other securities market
participants) will successfully complete the necessary changes in a timely
manner or that there will be no adverse impact on a Fund. Moreover, the Funds at
this time have not considered retaining alternative service providers or
directly undertaken efforts to achieve year 2000 readiness, the latter of which
would involve substantial expenses without an assurance of success.

      Additionally, issuers of securities generally, as well as those purchased
by a Fund, may confront year 2000 compliance issues which, if material and not
resolved, could have an adverse impact on securities markets and/or a specific
issuer's performance and could result in a decline in the value of the
securities held by a Fund.

FUND DISTRIBUTIONS AND TAX ISSUES
- --------------------------------------------------------------------------------

Investors who buy shares of a Fund should be aware of some important tax issues.
For example, each Fund distributes DIVIDENDS of ordinary income and any realized
net CAPITAL GAINS to shareholders. These distributions are subject to taxes,
unless you hold your shares in a 401(k) plan, an Individual Retirement Account
(IRA), or some other qualified tax-deferred plan or account.

      Also, if you sell shares of a Fund for a profit, you may have to pay
capital gains taxes on the amount of your profit, again unless you hold your
shares in a qualified tax-deferred plan or account.

      The following briefly discusses some of the important federal tax issues
you should be aware of, but is not meant to be tax advice. For tax advice,
please speak with your tax adviser.

DISTRIBUTIONS

      Each Fund declares daily and distributes DIVIDENDS of any net investment
income to shareholders once a year. For example, if a Fund owns Acme Corp. stock
and the stock pays a dividend, the Fund will pay out a portion of this dividend
to its shareholders, assuming the Fund's income is more than its costs and
expenses. The dividends you receive from a Fund will be taxed as ordinary income
whether or not they are reinvested in the Fund.

      Each Fund also distributes realized net CAPITAL GAINS to shareholders--
typically once a year--which are generated when a Fund sells its assets for a
profit. For example, if a Fund bought Acme Corp. stock for a total of $1,000 and
more than one year later sold the shares for a total of $1,500, the Fund has net
long-term capital gains of $500, which it will pass on to shareholders (assuming
the Fund's total gains are greater than any losses it may have). Capital gains
are taxed differently depending on how long a Fund holds the security--if a
security is held more than one year before it is sold, LONG-TERM capital gains
are taxed at the rate of 20%, but if the security is held one year or less,
SHORT-TERM capital gains are taxed at ordinary income rates of up to 39.6%.
Different rates apply to corporate shareholders.

      For your convenience, a Fund's distributions of dividends and capital
gains are AUTOMATICALLY REINVESTED in the Fund without any sales charge. If you
ask us to pay the distributions in cash, we will send you a check if your
account is with the Transfer Agent. Otherwise, if your account is with a broker,
you will receive a credit to your account. Either way, the distributions may be
subject to taxes, unless your shares are held in a qualified tax-deferred plan
or account. For more information about automatic reinvestment and other
shareholder services, see "Step 4: Additional Shareholder Services" in the next
section.



- --------------------------------------------------------------------------------
                                                                              25

- --------------------------------------------------------------------------------
FUND DISTRIBUTIONS AND TAX ISSUES
- --------------------------------------------------------------------------------

TAX ISSUES
FORM 1099

Every year, you will receive a Form 1099, which reports the amount of dividends
and capital gains we distributed to you during the prior year. If you own shares
of a Fund as part of a qualified tax-deferred plan or account, your taxes are
deferred, so you will not receive a Form 1099. However, you will receive a Form
1099 when you take any distributions from your qualified tax-deferred plan or
account.

      Fund distributions are generally taxable to you in the calendar year they
are received, except when we declare certain dividends in the fourth quarter and
actually pay them in January of the following year. In such cases, the dividends
are treated as if they were paid on December 31 of the prior year. Corporate
shareholders are eligible for the 70% dividends-received deduction for certain
dividends.

WITHHOLDING TAXES

If federal tax law requires you to provide a Fund with your tax identification
number and certifications as to your tax status, and you fail to do this, we
will withhold and pay to the U.S. Treasury 31% of your distributions and sale
proceeds. If you are subject to backup withholding, we will withhold and pay to
the U.S. Treasury 31% of your distributions. Dividends of net investment income
and short-term capital gains paid to a nonresident foreign shareholder generally
will be subject to a U.S. withholding tax of 30%. This rate may be lower,
depending on any tax treaty the U.S. may have with the shareholder's country.

IF YOU PURCHASE JUST BEFORE RECORD DATE

If you buy shares of a Fund just before the record date (the date that
determines who receives the distribution), that distribution will be paid to
you. As explained above, the distribution may be subject to income or capital
gains taxes. You may think you've done well since you bought shares one day and
soon thereafter received a distribution. That is not so because when dividends
are paid out, the value of each share of a Fund decreases by the amount of the
dividend and the market changes (if any) to reflect the payout. The distribution
you receive makes up for the decrease in share value. However, the timing of
your purchase does mean that part of your investment came back to you as taxable
income.

FUND DISTRIBUTIONS AND TAX ISSUES
- --------------------------------------------------------------------------------

QUALIFIED RETIREMENT PLANS

Retirement plans and accounts allow you to defer paying taxes on investment
income and capital gains. Contributions to these plans may also be tax
deductible, although distributions from these plans generally are taxable. In
the case of Roth IRA accounts, contributions are not tax deductible, but
distributions from the plan may be tax free. Please contact your financial
adviser for information on a variety of Prudential mutual funds that are
suitable for retirement plans offered by Prudential.

IF YOU SELL OR EXCHANGE YOUR SHARES

If you sell any shares of a Fund for a profit, you have REALIZED A CAPITAL GAIN,
which is subject to tax, unless you hold shares in a qualified tax-deferred plan
or account. The amount of tax you pay depends on how long you owned your shares.
If you sell shares of a Fund for a loss, you may have a capital loss, which you
may use to offset certain capital gains you have.

- --------------------------------------------------------------------------------

                                   +$ Capital Gain
                  Receipts---->      (taxes owed)
                    from         or
                    Sale----->      -$ Capital Loss
                                     (offset against gain)

- --------------------------------------------------------------------------------

      Exchanging your shares of a Fund for the shares of another Prudential
mutual fund is considered a sale for tax purposes. In other words, it's a
"taxable event." Therefore, if the shares you exchanged have increased in value
since you purchased them, you have capital gains, which are subject to the taxes
described above.

      Any gain or loss you may have from selling or exchanging Fund shares will
not be reported on Form 1099; however, proceeds from the sale or exchange will
be reported on Form 1099-B. Therefore, unless you hold your shares in a
qualified tax-deferred plan or account, you or your financial adviser should
keep track of the dates on which you buy and sell--or exchange--Fund shares, as
well as the amount of any gain or loss on each transaction. For tax advice,
please see your tax adviser.

QUALIFYING FOR CLASS Z SHARES

Certain group retirement plans may purchase Class Z shares provided that they
meet the required minimum amount of assets, average account balance or number of
eligible employees. For more information about these requirements, call
Prudential at (800) 353-2847.

MUTUAL FUND PROGRAMS. Class Z shares can also be purchased by participants in
any fee-based program or trust program sponsored by Prudential or an affiliate
which includes mutual funds as investment options and the Fund as an available
option. Class Z shares also can be purchased by investors in certain programs
sponsored by broker-dealers, investment advisers and financial planners who have
agreements with Prudential Investments Advisory Group relating to:

      o     Mutual fund "wrap" or asset allocation programs, where the sponsor
            places Fund trades, links its clients' accounts to a master account
            in the sponsor's name and charges a management, consulting or other
            fee for its services

      o     Mutual fund "supermarket" programs, where the sponsor links its
            customers' accounts to a master account in the sponsor's name and
            the sponsor charges a fee for its services.

OTHER TYPES OF INVESTORS. Class Z shares also can be purchased by any of the
following:

      o     Certain participants in the MEDLEY Program (group variable annuity
            contracts) sponsored by Prudential for whom Class Z shares of the
            Prudential mutual funds are an available option

      o     Current and former Directors/Trustees of the Prudential mutual funds
            (including the Company)

      o     Prudential with an investment of $10 million or more.

      In connection with the sale of shares, the Manager, the Distributor or one
of their affiliates may pay brokers, financial advisers and other persons a
finder's fee for Class Z shares from their own resources based on a percentage
of the net asset value of shares sold or otherwise.

STEP 3: UNDERSTANDING THE PRICE YOU'LL PAY

The price you pay for each share of a Fund is based on the share value. The
share value of a mutual fund--known as the NET ASSET VALUE or NAV--is determined
by a simple calculation: it's the total value of the Fund (assets minus
liabilities) divided by the total number of shares outstanding. For example, if
the value of the investments held by Fund XYZ (minus its liabilities) is $1,000
and there are 100 shares of Fund XYZ owned by shareholders, the price of one
share of the fund--or the NAV--is $10 ($1,000 divided by 100). Portfolio
securities are valued based upon market quotations or, if not readily available,
at fair value as determined in good faith under procedures established by the
Company's Board. Most national newspapers report the NAVs of most mutual funds,
which allows investors to check the price of mutual funds daily.

      We determine the NAV of our shares once each business day at 4:15 p.m. New
York Time on days that the New York Stock Exchange is open for trading. We do
not determine the NAV on days when we have not received any orders to purchase,
sell or exchange Fund shares, or when changes in the value of a Fund's portfolio
do not materially affect the NAV.

- --------------------------------------------------------------------------------
MUTUAL FUND SHARES

The NAV of mutual fund shares changes every day because the value of a fund's
portfolio changes constantly. For example, if Fund XYZ holds ACME Corp. stock in
its portfolio and the price of ACME stock goes up while the value of the fund's
other holdings remains the same and expenses don't change, the NAV of Fund XYZ
will increase.
- --------------------------------------------------------------------------------

WHAT PRICE WILL YOU PAY FOR SHARES OF A FUND?

You will pay the NAV next determined after we receive your order to purchase
(remember, there are no up-front sales charges for these share classes). Your
broker may charge a separate or additional fee for purchases of shares.

STEP 4: ADDITIONAL SHAREHOLDER SERVICES

As a Fund shareholder, you can take advantage of the following services and
privileges:

AUTOMATIC REINVESTMENT. As we explained in the "Fund Distributions and Tax
Issues" section, each Fund pays out--or distributes--its net investment income
and capital gains to all shareholders. For your convenience, we will
automatically reinvest your distributions in your Fund at NAV, without any sales
charge. If you want your distributions paid in cash, you can indicate this
preference on your application, notify your broker or notify the Transfer Agent
in writing (at the address below) at least five business days before the date we
determine who receives dividends.

PRUDENTIAL MUTUAL FUND SERVICES LLC
ATTN: ACCOUNT MAINTENANCE
P.O. BOX 15015
NEW BRUNSWICK, NJ 08906-5015

AUTOMATIC INVESTMENT PLAN. You can make regular purchases of a Fund for as
little as $50 by having the funds automatically withdrawn from your bank or
brokerage account at specified intervals.

RETIREMENT PLAN SERVICES. Prudential offers a wide variety of retirement plans
for individuals and institutions, including large and small businesses. For
information on IRAs, including Roth IRAs, or SEP IRAs for a one-person business,
please contact your financial adviser. If you are interested in opening a 401(k)
or other company-sponsored retirement plan (SIMPLES, SEP plans, Keoghs, 403(b)
plans, pension and profit-sharing plans), your financial adviser will help you
determine which retirement plan best meets your needs. Complete instructions
about how to establish and maintain your plan and how to open accounts for you
and your employees will be included in the retirement plan kit you receive in
the mail.

THE PRUTECTOR PROGRAM. Optional group term life insurance--which protects the
value of your Prudential mutual fund investment for your beneficiaries against
market declines--is available to investors who purchase their shares through
Prudential. This insurance is subject to various restrictions and charges and is
not available in all states.

SYSTEMATIC WITHDRAWAL PLAN. A systematic withdrawal plan is available that will
provide you with monthly or quarterly checks.

REPORTS TO SHAREHOLDERS. Every year we will send you an annual report (along
with an updated prospectus) and a semi-annual report, which contain important
financial information about the Funds. To reduce Fund expenses, we will send one
annual shareholder report, one semi-annual shareholder report and one annual
prospectus per household, unless you instruct us or your broker otherwise.

HOW TO SELL YOUR SHARES

You can sell your shares of a Fund for cash (in the form of a check) at any
time, subject to certain restrictions.

      When you sell shares of the Fund--also known as redeeming your shares--the
price you will receive will be the NAV next determined after the Transfer Agent,
the Distributor or your broker receives your order to sell. If your broker holds
your shares, your broker must receive your order to sell by 4:15 p.m. New York
Time to process the sale on that day. Otherwise contact:

PRUDENTIAL MUTUAL FUND SERVICES LLC
ATTN: REDEMPTION SERVICES
P.O. BOX 15010
NEW BRUNSWICK, NJ 08906-5010

      Generally, we will pay you for the shares that you sell within seven days
after the Transfer Agent, the Distributor or your broker receives your sell
order. If you hold shares through a broker, payment will be credited to your
account. If you are selling shares you recently purchased with a check, we may
delay sending you the proceeds until your check clears, which can take up to 10
days from the purchase date. You can avoid delay if you purchase by wire,
certified

check or cashier's check. Your broker may charge you a separate or additional
fee for sales of shares.

RESTRICTIONS ON SALES

There are certain times when you may not be able to sell shares of a Fund, or
when we may delay paying you the proceeds from a sale. This may happen during
unusual market conditions or emergencies when the Fund can't determine the value
of its assets or sell its holdings. For more information, see the SAI,
"Purchase, Redemption and Pricing of Fund Shares--Sale of Shares."

      If you are selling more than $100,000 of shares, you want the check sent
to someone or some place that is not in our records, or you are a business or a
trust and you hold your shares directly with the Transfer Agent, you will need
to have the signature on your sell order guaranteed by a financial institution.
For more information, see the SAI, "Purchase, Redemption and Pricing of Fund
Shares--Sale of Shares--Signature Guarantee."

REDEMPTION IN KIND

If the sales of a Fund's shares you make during any 90-day period reach the
lesser of $250,000 or 1% of the value of the Fund's net assets, we can then give
you securities from the Fund's portfolio instead of cash. If you want to sell
the securities for cash, you would have to pay the costs charged by a broker.

90-DAY REPURCHASE PRIVILEGE

After you redeem your shares, you have a 90-day period during which you may
reinvest any of the redemption proceeds in shares of the same Fund without
paying an initial sales charge. Also, if you paid a CDSC when you redeemed your
shares, we will credit your new account with the appropriate number of shares to
reflect the amount of the CDSC you paid. In order to take advantage of this
one-time privilege, you must notify the Transfer Agent or your broker at the
time of the repurchase. See the SAI, "Purchase, Redemption and Pricing of Fund
Shares--Sale of Shares."

RETIREMENT PLANS

To sell shares and receive a distribution from your retirement account, call
your broker or the Transfer Agent for a distribution request form. There are
special distribution and income tax withholding requirements for distributions
from retirement plans and you must submit a withholding form with your request
to

avoid delay. If your retirement plan account is held for you by your employer or
plan trustee, you must arrange for the distribution request to be signed and
sent by the plan administrator or trustee. For additional information, see the
SAI.

HOW TO EXCHANGE YOUR SHARES

You can exchange your shares of a Fund for Class Z shares in certain other
Prudential mutual funds--as well as certain money market funds--if you satisfy
the minimum investment requirements. For example, you can exchange Class Z
shares of the Fund for Class Z shares of another Prudential mutual fund, but you
can't exchange Class Z shares for Class A, Class B or Class C shares. We may
change the terms of the exchange privilege after giving you 60 days' notice.

      If you hold shares through a broker, you must exchange shares through your
broker. Otherwise contact:

      Remember, as we explained in the section entitled "Fund Distributions and
Tax Issues--If You Sell or Exchange Your Shares," exchanging shares is
considered a sale for tax purposes. Therefore, if the shares you exchange are
worth more than you paid for them, you may have to pay capital gains tax. For
additional information about exchanging shares, see the SAI, "Shareholder
Investment Account--Exchange Privilege."

FREQUENT TRADING

Frequent trading of Fund shares in response to short-term fluctuations in the
market--also known as "market timing"--may make it very difficult to manage a
Fund's investments. When market timing occurs, a Fund may have to sell portfolio
securities to have the cash necessary to redeem the market timer's shares. This
can happen at a time when it is not advantageous to sell any securities, so the
Fund's performance may be hurt. When large dollar amounts are involved, market
timing can also make it difficult to use long-term investment strategies because
we cannot predict how much cash a Fund will have to invest. When, in our
opinion, such activity would have a disruptive effect on portfolio management,
each Fund reserves the right to refuse purchase orders and exchanges into the
Fund by any person, group or commonly controlled account. A Fund may notify a
market timer of rejection of an exchange or purchase order after the day the
order is placed. If a Fund allows a market timer to trade Fund shares, it may
require the market timer to enter into a written agreement to follow certain
procedures and limitations.

                                  FUND HISTORY


      The Company changed its name from The Prudential Institutional Fund to
Prudential Dryden Fund effective October 30, 1996. In addition, Stock Index Fund
changed its name to Prudential Stock Index Fund at the same time. On February
19, 1997, the Trustees approved the addition of the following four Funds to the
Company: Prudential Bond Market Index Fund, Prudential Europe Index Fund,
Prudential Pacific Index Fund and Prudential Small-Cap Index Fund. The Company
changed its name from Prudential Dryden Fund to Prudential Index Series Fund
effective January 23, 1998.


              DESCRIPTION OF THE FUNDS, THEIR INVESTMENTS AND RISKS



      (A) CLASSIFICATION. The Company is a diversified, open-end, management
investment company.



      (B) AND (C) INVESTMENT STRATEGIES, POLICIES AND RISKS. Each Fund has an
investment objective of providing investment results that correspond to the
performance of a specific broad-based index of securities. In seeking to track a
particular index, a fund generally uses one of two methods to select stocks or
bonds in which it invests. Prudential Stock Index Fund intends to invest at
least 80% of its total assets in securities included in its corresponding index.
In other words, it holds each stock or bond in its target index in about the
same proportions as represented in the Index itself. This is called a
"replication" method.



      Other index funds may use a different security selection process. Because
it would be very expensive to buy and sell all of the securities held in certain
indexes, funds tracking these indexes use a "sampling" technique. Using
sophisticated computer programs, the funds select securities that will recreate
their target indexes in terms of industry weightings, market capitalization and
other characteristics. Each of Prudential Bond Market Index Fund, Prudential
Europe Index Fund, Prudential Pacific Index Fund and Prudential Small-Cap Index
Fund uses this method of indexing. While the principal investment policies and
strategies for seeking to achieve these objectives are described in the Funds'
prospectuses, each Fund may from time to time also use the securities,
instruments, policies and strategies described below in seeking to achieve its
objective. A Fund may not be successful in achieving its objective and you could
lose money.



      The investment objective of Prudential Bond Market Index Fund is to seek
to provide investment results that correspond to the total return performance of
a broad-based index of fixed-income securities. The Prudential Bond Market Index
Fund currently uses the Lehman Brothers Aggregate Index for that purpose.



      The investment objective of Prudential Europe Index Fund is to seek to
provide investment results that correspond to the price and yield performance of
a broad-based index of securities of European issuers. The Prudential Europe
Index Fund currently uses the MSCI-Europe Index for that purpose.



      The investment objective of Prudential Pacific Index Fund is to seek to
provide investment results that correspond to the price and yield performance of
a broad-based index of securities of issuers in the Pacific region. The
Prudential Pacific Index Fund currently uses the MSCI-Pacific Free Index for
that purpose.



      The investment objective of Prudential Small-Cap Index Fund is to seek to
provide investment results that correspond to the price and yield performance of
a broad-based index of small cap stocks. The Prudential Small-Cap Index Fund
currently uses the S&P 600 Index for that purpose.



      The investment objective of Prudential Stock Index Fund is to seek to
provide investment results that correspond to the price and yield performance of
the S&P 500 Index.



      The investment objective of Prudential Stock Index Fund is fundamental.
Each other Fund's investment objective and the investment policies (other than
their investment restrictions) of all Funds are not fundamental and so may be
changed by the Board of Trustees (Trustees) without shareholder approval.
However, shareholders would be notified prior to a material change in a Fund's
investment objective and policies. The broad-based indices used by the Funds
(except Prudential Stock Index Fund) may be changed from time to time at the
discretion of the Subadviser under the supervision of the Trustees.



      The Funds are not managed according to traditional methods of "active"
investment management, which involve the buying and selling of securities based
upon economic, financial and market analysis and investment judgment.



                                      B-2
<PAGE>


Instead, the investment adviser for the Funds, using a "passive" or indexing
investment approach, will attempt to approximate the investment performance of
the respective indices by holding a portfolio of stocks or bonds selected
through statistical procedures. The Funds are managed without regard to tax
ramifications. Each Fund pursues its objective through the investment policies
described below. While each Fund will seek to achieve its objective, the Funds
will differ with respect to the degree of risk that they involve.



      PRUDENTIAL BOND MARKET INDEX FUND



      Prudential Bond Market Index Fund seeks to provide investment results that
correspond to the total return performance of a broad-based index of
fixed-income securities. The Prudential Bond Market Index Fund currently uses
the Lehman Brothers Aggregate Index for that purpose. The Lehman Brothers
Aggregate Index is an unmanaged index that measures the total return (capital
change plus income) provided by a universe of fixed-income securities, weighted
by market value. The Fund is neither sponsored by nor affiliated with Lehman
Brothers Inc. See "Investment Objectives and Policies--Investment Policies
Applicable to Prudential Bond Market Index Fund" in the Statement of Additional
Information.



      To achieve its investment objective, Prudential Bond Market Index Fund
will purchase securities that as a group reflect the performance of the Lehman
Brothers Aggregate Index. The Fund intends to hold a representative sample of
the securities that reflect the three major classes of fixed-income investments
in the Lehman Brothers Aggregate Index: U.S. Treasury and Government agency
securities, investment-grade corporate debt obligations and mortgage-backed
securities. The securities included in the Index must be U.S. dollar-denominated
and investment-grade, and have a fixed rate coupon, a remaining maturity or
average life of at least one year and generally have an outstanding market value
of at least $100 million. In addition, from time to time adjustments may be made
in the holdings of the Fund due to factors which may include changes in the
composition of the Lehman Brothers Aggregate Index. As of September 30, 1998,
U.S. Treasury and agency securities comprised 42% and 4%, respectively, of the
Index's total market value, corporate bonds comprised 21%, asset-backed
securities comprised 2% and mortgage-backed securities comprised 31%.



      Prudential Bond Market Index Fund intends to invest at least 80% of its
total assets in the types of securities included in the Lehman Brothers
Aggregate Index in the same proportions as the Index. The Fund may invest the
balance of its assets in: (i) money market instruments; (ii) put and call
options on fixed-income securities and bond indices; and (iii) bond futures
contracts and options thereon.


      If net cash outflows from Prudential Bond Market Index Fund are
anticipated, the Fund may sell securities (in proportion to their weighting in
the Lehman Brothers Aggregate Index) in amounts in excess of those needed to
satisfy the cash outflows and hold the balance of the proceeds in short-term
investments if such a transaction appears, taking into account transaction
costs, to be more efficient than selling only the amount of securities needed to
meet the cash requirements. If Prudential Bond Market Index Fund does hold
unhedged short-term investments as a result of the patterns of cash flows to and
from the Fund, such holdings may cause its performance to differ from that of
the Lehman Brothers Aggregate Index.

      The Fund is not sponsored, endorsed, sold or promoted by Lehman Brothers
Inc.

      MORTGAGE-BACKED SECURITIES

      Mortgage-backed securities may be classified as private, governmental or
government related, depending on the issuer or guarantor. Private
mortgage-backed securities represent pass-through pools consisting principally
of conventional residential mortgage loans created by non-governmental issuers,
such as commercial banks, savings and loan associations and private mortgage
insurance companies. Governmental mortgage-backed securities are backed by the
full faith and credit of the United States. Government National Mortgage
Association (GNMA), the principal U.S. guarantor of such securities, is a wholly
owned corporate instrumentality of the United States within the Department of
Housing and Urban Development. Pass-through securities issued by the Federal
National Mortgage Association (FNMA) are guaranteed as to timely payment of
principal and interest by FNMA, which guarantee is not backed by the full faith
and credit of the U.S. Government. The Federal Home Loan Mortgage Corporation
(FHLMC) is a corporate instrumentality of the United States, the stock of which
is owned by the Federal Home Loan Banks. Participation certificates representing
interests in mortgages from FHLMC's national portfolio are guaranteed as to the
timely payment of interest and ultimate, but generally not timely, collection of
principal by FHLMC. The obligations of the FHLMC under its guarantee are
obligations solely of FHLMC and are not backed by the full faith and credit of
the U.S. Government.


                                      B-3
<PAGE>

      Prudential Bond Market Index Fund expects that private and governmental
entities may create mortgage loan pools offering pass-through investments in
addition to those described above. The mortgages underlying these securities may
be alternative mortgage instruments, that is, mortgage instruments whose
principal or interest payments may vary or whose terms to maturity may be
shorter than previously customary. As new types of mortgage-backed securities
are developed and offered to investors, the Fund, consistent with its investment
objective and policies, will consider making investments in those new types of
securities.

      The average maturity of pass-through pools of mortgage-backed securities
varies with the maturities of the underlying mortgage instruments. In addition,
a pool's stated maturity may be shortened by unscheduled payments on the
underlying mortgages. Factors affecting mortgage prepayments include the level
of interest rates, general economic and social conditions, the location of the
mortgaged property and age of the mortgage. Because prepayment rates of
individual pools vary widely, it is not possible to predict accurately the
average life of a particular pool. Common practice is to assume that prepayments
will result in an average life ranging from two to ten years for pools of fixed
rate 30-year mortgages. Pools of mortgages with other maturities or different
characteristics will have varying average life assumptions.

      Because prepayments of principal generally occur when interest rates are
declining, it is likely that the Fund will have to reinvest the proceeds of
prepayments at lower interest rates than those at which the assets were
previously invested. If this occurs, the Fund's yield will correspondingly
decline. Thus, mortgage-backed securities may have less potential for capital
appreciation in periods of falling interest rates than other fixed income
securities of comparable maturity, although these securities may have a
comparable risk of decline in market value in periods of rising interest rates.
To the extent that the Fund purchases mortgage-backed securities at a premium,
unscheduled prepayments, which are made at par, will result in a loss equal to
any unamortized premium.


      PRUDENTIAL EUROPE INDEX FUND



      Prudential Europe Index Fund seeks to provide investment results that
correspond to the price and yield performance of a broad-based index of
securities of European issuers. The Prudential Europe Index Fund currently uses
the MSCI-Europe Index for that purpose. The MSCI-Europe Index is an unmanaged,
diversified, capitalization weighted index currently consisting of the equity
securities of 592 companies located in 15 developed European countries. These
countries are: Austria, Belgium, Denmark, Finland, France, Germany, Ireland,
Italy, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United
Kingdom. The Fund is neither sponsored by nor affiliated with Morgan Stanley &
Co. Incorporated. See "Investment Objectives and Policies--Investment Policies
Applicable to Prudential Europe Index Fund" in the Statement of Additional
Information.



      To achieve its investment objective, Prudential Europe Index Fund will
purchase the equity securities that as a group reflect the price and yield
performance of the MSCI-Europe Index. The Fund intends to invest in a
representative sample of the stocks included in the MSCI-Europe Index in
approximately the same proportions as they are represented in that index. In
addition, from time to time adjustments may be made in the holdings of the Fund
due to factors which may include changes in the composition of the MSCI-Europe
Index. The United Kingdom, Germany and France dominate the MSCI-Europe Index,
with 31.1%, 15.1% and 12.9%, respectively, of the market capitalization of the
Index as of September 30, 1998.



      Prudential Europe Index Fund intends to invest at least 80% of its total
assets in securities included in the MSCI-Europe Index in the same proportions
as the Index. The Fund may invest the balance of its assets in: (i) money market
instruments; (ii) equity-related securities; (iii) put and call options on
securities, stock indices and foreign currencies; (iv) forward foreign currency
exchange contracts; and (v) financial futures contracts on stocks and currencies
and options thereon.


      If net cash outflows from Prudential Pacific Index Fund are anticipated,
the Fund may sell stocks (in proportion to their weighting in the Morgan Stanley
Capital International Pacific Free Index (MSCI-Pacific Free Index)) in amounts
in excess of those needed to satisfy the cash outflows and hold the balance of
the proceeds in short-term investments if such a transaction appears, taking
into account transaction costs, to be more efficient than selling only the
amount of stocks needed to meet the cash requirements. If Prudential Pacific
Index Fund does hold unhedged short-term investments as a result of the patterns
of cash flows to and from the Fund, such holdings may cause its performance to
differ from that of the MSCI-Pacific Free Index.

      PRUDENTIAL PACIFIC INDEX FUND



      Prudential Pacific Index Fund seeks to provide investment results that
correspond to the price and yield performance of a broad-based index of
securities of issuers in the Pacific region. The Prudential Pacific Index Fund
currently uses the MSCI-Pacific Free Index for that purpose. The MSCI-Pacific
Free Index is an unmanaged, diversified, capitalization weighted index currently
consisting of 508 equity securities listed on the stock exchanges of Australia,
Japan, Hong Kong, New Zealand and Singapore. The Fund is neither sponsored by
nor affiliated with Morgan Stanley & Co Incorporated.



      To achieve its investment objective, Prudential Pacific Index Fund will
purchase the equity securities that as a group reflect the price and yield
performance of the MSCI-Pacific Free Index. The Fund intends to invest in a
representative sample of the equity securities included in the MSCI-Pacific Free
Index in approximately the same proportions as they are represented in the
MSCI-Pacific Free Index. In addition, from time to time adjustments may be made
in the holdings of the Fund due to factors which may include changes in the
composition of the MSCI-Pacific Free Index. The MSCI-Pacific Free Index is
dominated by the Japanese stock market, which represented 78% of the market
capitalization of the Index as of September 30, 1998.



      Prudential Pacific Index Fund intends to invest at least 80% of its total
assets in securities included in the MSCI-Pacific Free Index in the same
proportions as the Index. The Fund may invest the balance of its assets in: (i)
money market instruments; (ii) equity-related securities; (iii) put and call
options on securities, stock indices and foreign currencies; (iv) forward
foreign currency exchange contracts; and (v) financial futures contracts on
stocks and currencies and options thereon.


      If net cash outflows from Prudential Europe Index Fund are anticipated,
the Fund may sell stocks (in proportion to their weighting in the Morgan Stanley
Capital International Europe Index (MSCI-Europe Index)) in amounts in excess of
those needed to satisfy the cash outflows and hold the balance of the proceeds
in short-term investments if such a transaction appears, taking into account
transaction costs, to be more efficient than selling only the amount of stocks

      PRUDENTIAL SMALL-CAP INDEX FUND



      Prudential Small-Cap Index Fund seeks to provide investment results that
correspond to the price and yield performance of a broad-based index of
small-cap stocks. The Prudential Small-Cap Index Fund currently uses the S&P 600
Index for that purpose. The S&P 600 Index is an unmanaged, market-value weighted
index (stock price times the number of shares outstanding) of 600 smaller
company U.S. common stocks that cover all industry sectors. Inclusion in the S&P
600 Index in no way implies an opinion by Standard & Poor's Corporation (S&P) as
to a stock's attractiveness as an investment. The S&P 600 Index currently
measures the performance of selected U.S. stocks with a market value of no
greater than $3.212 million (as of September 30, 1998). "S&P 600(R)," "Standard
& Poor's 600" and "600" are trademarks of McGraw-Hill, Inc. and have been

regarding the advisability of investing in the Fund.



      To achieve its investment objective, Prudential Small-Cap Index Fund will
purchase equity securities that as a group reflect the price and yield
performance of the S&P 600 Index. The Fund intends to purchase a representative
sample of the 600 stocks included in the S&P 600 Index in approximately the same
proportions as they are represented in the S&P 600 Index. In addition, from time
to time adjustments may be made in the holdings of the Fund due to factors which
may include changes in the composition of the S&P 600 Index or receipt of
distributions of securities of companies spun off from S&P 600 companies.

      PRUDENTIAL STOCK INDEX FUND



      Prudential Stock Index Fund seeks to provide investment results that
correspond to the price and yield performance of the S&P 500 Index. The S&P 500
Index is an unmanaged, market-weighted index of 500 stocks selected by S&P on
the basis of their market size, liquidity and industry group representation.
Inclusion in the S&P 500 Index in no way implies an opinion by S&P as to a
stock's attractiveness as an investment. The S&P 500 Index, composed of stocks
representing more than 70% of the total market value of all publicly traded U.S.
common stocks, is widely regarded as representative of the performance of the
U.S. stock market as a whole. "Standard & Poors(R)", "S&P(R)", "S&P 500(R)",
"Standard & Poor's 500", and "500" are trademarks of McGraw-Hill, Inc. and have

regarding certain additional disclaimers and limitations of liability on behalf
of S&P.



      To achieve its investment objective, the Fund will purchase equity
securities that as a group reflect the price and yield performance of the S&P

sample of the 500 stocks included in the S&P 500 Index in approximately the same
proportions as they are represented in the S&P 500 Index. In addition, from time

      INVESTMENT POLICIES APPLICABLE TO EACH FUND



      The Funds are each expected to invest in over 250 stocks (or bonds for the
Prudential Bond Market Index Fund). Stocks are selected for inclusion in each
applicable Fund's portfolio based on country, market capitalization, industry
weightings and fundamental characteristics such as return variability, earnings
valuation and yield. Each Fund's portfolio is constructed to have aggregate
investment characteristics similar to those of its respective index. In order to
parallel the performance of its respective index, Prudential Europe Index Fund
and Prudential Pacific Index Fund will invest in each country in approximately
the same percentage as the country's weight in the index.



      The Funds may not hold all of the issues that comprise their respective
indices because of the costs involved and the illiquidity of many of the
securities. Instead, each Fund will attempt to hold a representative sample of
the securities in its respective index, which will be selected utilizing a
statistical technique known as "portfolio optimization." Under this technique,
each stock is considered for inclusion in the portfolio based on its
contribution



                                      B-7
<PAGE>


to certain country, capitalization, industry and fundamental investment
characteristics. Each applicable Fund's portfolio is constructed so that, in the
aggregate, the country, capitalization, industry and fundamental investment
characteristics resemble those of its respective index. Over time, portfolio
composition is altered (or "rebalanced") to reflect changes in the
characteristics of the indices.



      Due to the use of this sampling or "portfolio optimization" technique, the
Funds' portfolios (other than the portfolio of Prudential Stock Index Fund) are
not expected to track their benchmark indices with the same degree of accuracy
as large capitalization domestic index funds. Each Fund will attempt to achieve
a correlation between its performance and that of its respective index of at
least 0.95, in each case without taking into account expenses. A correlation of
1.00 would indicate perfect correlation, which would be achieved when a Fund's
net asset value, including the value of its dividends and capital gains
distributions, increases or decreases in exact proportion to changes in its
respective index. The investment adviser will, of course, attempt to minimize
any tracking differential (I.E., the statistical measure of the difference
between the investment results of a Fund and that of its respective index).
Tracking will be monitored at least on a monthly basis. All tracking maintenance
activities will be reviewed regularly to determine whether any changes in
policies or techniques are necessary. However, in addition to potential tracking
differences, brokerage and other transaction costs, as well as other expenses,
may cause a Fund's return to be lower than the return of its respective index.
Consequently, there can be no assurance as to how closely a Fund's performance
will correspond to the performance of its respective index.



      The Funds will not invest in money market instruments, futures contracts,
options or warrants as part of a temporary defensive strategy, such as reducing
a Fund's investments in common stocks to protect against potential stock market
declines. The Funds intend to remain fully invested, to the extent practicable,
in a pool of securities which will approximate the investment characteristics of
their respective indices. Options, futures contracts and options on futures
contracts are used, if at all, primarily to invest uncommitted cash balances, to
maintain liquidity to meet redemptions, to facilitate tracking, to reduce
transaction costs or to hedge a Fund's portfolio. Prudential Europe Index Fund
and Prudential Pacific Index Fund also may enter into foreign currency forward
contracts in order to maintain the same currency exposure as their respective
indices, but not as part of a defensive strategy to protect against fluctuations
in exchange rates.



      In order to invest uncommitted cash balances, maintain liquidity to meet
redemptions, or for incidental return enhancement purposes, the Funds may also
(i) enter into repurchase agreements, when-issued, delayed delivery and forward
commitment transactions; and (ii) lend their portfolio securities.



      EQUITY AND EQUITY-RELATED SECURITIES



      EACH FUND OTHER THAN PRUDENTIAL BOND MARKET INDEX FUND INVESTS PRIMARILY
IN EQUITY SECURITIES, AND THE VALUE OF THESE FUNDS' INVESTMENTS WILL GO UP AND
DOWN WITH THE PERFORMANCE OF THE STOCKS IN THE APPLICABLE INDEX. INVESTMENT BY
PRUDENTIAL SMALL-CAP INDEX FUND IN SMALL COMPANIES INVOLVES GREATER RISK THAN IS
CUSTOMARILY ASSOCIATED WITH MORE ESTABLISHED COMPANIES. These companies often
have sales and earnings growth rates which exceed those of large companies;
however, smaller companies often have limited operating histories, product
lines, markets or financial resources, and may lack management depth. These
companies may be subject to intense competition from larger entities, and the
securities of these companies may have limited marketability and may be subject
to more abrupt or erratic movements in price than securities of larger companies
or the market averages in general.



      The Funds other than Prudential Bond Market Index Fund may invest in
equity-related securities. Equity-related securities include common stocks,
preferred stocks, securities convertible or exchangeable for common stocks or
preferred stocks, equity investments in partnerships, joint ventures, other
forms of non-corporate investments, American Depositary Receipts (ADRs),
American Depositary Shares (ADSs) and warrants and rights exercisable for equity
securities. See "Investment Objectives and Policies--Investment Policies
Applicable to Each of the Funds--Convertible Securities, Warrants and Rights" in
the Statement of Additional Information.



      ADRs and ADSs are U.S. dollar-denominated certificates or shares issued by
a United States bank or trust company and represent the right to receive
securities of a foreign issuer deposited in a domestic bank or foreign branch of
a U.S. bank and traded on a U.S. exchange or in an over-the-counter market.
Generally, ADRs are in registered form. There are no fees imposed on the
purchase or sale of ADRs when purchased from the issuing



                                      B-8
<PAGE>


bank or trust company in the initial underwriting, although the issuing bank or
trust company may impose charges for the collection of dividends and the
conversion of ADRs into the underlying securities. Investment in ADRs has
certain advantages over direct investment in the underlying foreign securities
since: (i) ADRs are U.S. dollar-denominated investments that are registered
domestically, easily transferable, and for which market quotations are readily
available; and (ii) issuers whose securities are represented by ADRs are usually
subject to comparable auditing, accounting and financial reporting standards as
domestic issuers.


      U.S. GOVERNMENT SECURITIES

      Securities issued or guaranteed by the U.S. Government or one of its
agencies, authorities or instrumentalities in which the Funds may invest include
debt obligations of varying maturities issued by the U.S. Treasury or issued or
guaranteed by an agency or instrumentality of the U.S. Government, including the
Federal Housing Administration, Farmers Home Administration, Export-Import Bank
of the U.S., Small Business Administration, GNMA, General Services
Administration, Central Bank for Cooperatives, Federal Farm Credit Banks,
Federal Home Loan Banks, FHLMC, Federal Intermediate Credit Banks, Federal Land
Banks, FNMA, Maritime Administration, Tennessee Valley Authority, District of
Columbia Armory Board, Student Loan Marketing Association and Resolution Trust
Corporation. Direct obligations of the U.S. Treasury include a variety of
securities that differ in their interest rates, maturities and dates of
issuance. Because the U.S. Government is not obligated by law to provide support
to an instrumentality that it sponsors, a Fund will invest in obligations issued
by an instrumentality of the U.S. Government only if the Fund's investment
adviser determines that the instrumentality's credit risk does not render its
securities unsuitable for investment by the Fund.

CONVERTIBLE SECURITIES, WARRANTS AND RIGHTS

      A convertible security is a bond, debenture, corporate note, preferred
stock or other similar security that may be converted into or exchanged for a
prescribed amount of common stock or other equity securities of the same or a
different issuer within a particular period of time at a specified price or
formula. A warrant or right entitles the holder to purchase equity securities at
a specific price for a specific period of time. Convertible securities are
senior to common stocks in a corporation's capital structure, but are usually
subordinated to similar nonconvertible securities. While providing a fixed
income stream (generally higher in yield than the income derivable from a common
stock but lower than that afforded by a similar nonconvertible security), a
convertible security also affords an investor the opportunity, through its
conversion feature, to participate in the capital appreciation dependent upon a
market price advance in the convertible security's underlying common stock.


      In general, the market value of a convertible security is at least the
higher of its "investment value" (that is, its value as a fixed-income security)
or its "conversion value" (that is, value upon conversion into its underlying
common stock). As a fixed-income security, a convertible security tends to
increase in market value when interest rates decline and tends to decrease in
value when interest rates rise. However, the price of a convertible security is
also influenced by the market value of the security's underlying stock. The
price of a convertible security tends to increase as the market value of the
underlying stock rises, whereas it tends to decrease as the market value of the
underlying stock declines. While no securities investment is without some risk,
investments in convertible securities generally entail less risk than
investments in the common stock of the same issuer.


      In recent years, convertibles have been developed which combine higher or
lower current income with options and other features. The Funds may invest in
these types of convertible securities.

      REPURCHASE AGREEMENTS AND REVERSE REPURCHASE AGREEMENTS


      Each Fund may enter into repurchase agreements whereby the seller of the
security agrees to repurchase that security from the Fund 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. A
Fund's repurchase agreements will at all times be fully collateralized in an
amount at least equal to the resale price. In the event of a default or
bankruptcy by a seller, the Fund that has entered into the repurchase agreement
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



                                      B-9
<PAGE>


repurchase are less than the repurchase price, the Fund will suffer a loss. Each
Fund may participate in a joint repurchase account managed by PIFM pursuant to
an order of the Commission.



      Each Fund has the authority to enter into reverse repurchase agreements,
dollar rolls and forward rolls, but no Fund plans to do so for the foreseeable
future; the Funds may enter into repurchase agreements. Each Fund may enter into
such agreements with banks and securities dealers that meet the creditworthiness
standards established by the Company's Trustees (Qualified Institutions). The
investment adviser will monitor the continued creditworthiness of Qualified
Institutions, subject to the oversight of the Company's Trustees. The resale
price of the securities purchased reflects the purchase price plus an agreed
upon market rate of interest which is unrelated to the coupon rate or date of
maturity of the purchased security. The Funds receive collateral equal to the
resale price, which is marked-to-market daily. These agreements permit each Fund
to keep all its assets earning interest while retaining "overnight" flexibility
to pursue investments of a longer-term nature.


      The use of repurchase agreements and reverse repurchase agreements involve
certain risks. For example, if the seller of securities under a repurchase
agreement defaults on its obligation to repurchase the underlying securities, as
a result of its bankruptcy or otherwise, a Fund will seek to dispose of such
securities, which action could involve costs or delays. If the seller becomes
insolvent and subject to liquidation or reorganization under applicable
bankruptcy or other laws, the Fund's ability to dispose of the underlying
securities may be restricted. Finally, it is possible that a Fund may not be
able to substantiate its interest in the underlying securities. To minimize this
risk, the securities underlying the agreement will be held by the Custodian at
all times in an amount at least equal to the repurchase price, including accrued
interest. If the counterparty fails to resell or repurchase the securities, a
Fund may suffer a loss to the extent proceeds from the sale of the underlying
collateral are less than the repurchase price.

      FIXED-INCOME SECURITIES


      Prudential Bond Market Index Fund will invest primarily in fixed-income
securities including U.S. Treasury obligations and securities issued or
guaranteed by U.S. Government agencies and instrumentalities, investment-grade
corporate debt obligations and mortgage-backed securities.



      U.S. Treasury securities, including bills, notes and bonds, 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. Obligations issued or guaranteed by
agencies of the U.S. Government or instrumentalities established or sponsored by
the U.S. Government may or may not be backed by the "full faith and credit" of
the United States.



      The Fund 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 Ratings) or Baa by Moody's Investors
Service (Moody's) or comparably rated by a similar nationally recognized
statistical rating organization (NRSRO) 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. See "Description of Ratings" in the Appendix.



      In general, the ratings of Moody's, S&P Ratings, Duff and Phelps, Inc.
(Duff & Phelps) and other NRSROs represent the opinions of those organizations
as to the quality of debt obligations that they rate. These ratings are relative
and subjective, are not absolute standards of quality and do not evaluate the
market risk of securities. These ratings will be among the initial criteria used
for the selection of portfolio securities. Among the factors that the rating
agencies consider are the long-term ability of the issuer to pay principal and
interest and general economic trends.


      Subsequent to its purchase by a Fund, an issue of debt obligations may
cease to be rated or its rating may be reduced below the minimum required for
purchase by the Fund. Neither event will require the sale of the debt obligation
by the Fund, but the Fund's Subadviser will consider the event in its
determination of whether the Fund should continue to hold the obligation. In
addition, to the extent that the ratings change as a result of changes in rating
organizations or their rating systems or owing to a corporate restructuring of
Moody's, S&P Ratings, Duff &


                                      B-10
<PAGE>


Phelps or another NRSRO, the Fund will attempt to use comparable ratings as
standards for its investments in accordance with its investment objectives and
policies.


      WHEN-ISSUED AND DELAYED DELIVERY SECURITIES


      The Funds 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 a Fund with payment and delivery taking
place in the future in order to secure what is considered to be an advantageous
price or yield to the Fund at the time of entering into the transaction. The
Funds' Custodian will segregate cash or other liquid assets having a value equal
to or greater than the Funds' purchase commitments. 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 a Fund's assets committed to the purchase of
securities on a when-issued or delayed delivery basis may increase the
volatility of the Fund's net asset value.


      To secure prices deemed advantageous at a particular time, each Fund may
purchase securities on a when-issued or delayed delivery basis, in which case
delivery of the securities occurs beyond the normal settlement period; payment
for or delivery of the securities would be made at the same time or prior to the
reciprocal delivery or payment by the other party to the transaction. A Fund
will enter into when-issued or delayed delivery transactions for the purpose of
acquiring securities and not for the purpose of leverage. When-issued securities
purchased by a Fund may include securities purchased on a "when, as and if
issued" basis under which the issuance of the securities depends on the
occurrence of a subsequent event, such as approval of a merger, corporate
reorganization or debt restructuring.

      Securities purchased on a when-issued or delayed delivery basis may expose
a Fund to risk because the securities may experience fluctuations in value prior
to their actual delivery. A Fund does not accrue income with respect to a
when-issued or delayed delivery security prior to its stated delivery date.
Purchasing securities on a when-issued or delayed delivery basis may involve the
additional risk that the yield available in the market when the delivery takes
place may be higher than that obtained in the transaction itself.

      SECURITIES LENDING


      Each Fund 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 other liquid assets or secures an
irrevocable letter of credit in favor of the Fund in an amount equal to at least
100%, determined daily, of the market value of the securities loaned which are
segregated pursuant to applicable regulations. During the time portfolio
securities are on loan, the borrower will pay the Fund that has loaned its
portfolio securities an amount equivalent to any dividend or interest paid on
such securities and that Fund may invest the cash collateral and earn additional
income, or it may receive an agreed-upon amount of interest income from the
borrower. As with any extension 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. As a matter of fundamental policy, a Fund will not
lend more than 30% of the value of its total assets. A Fund may pay reasonable
administration and custodial fees in connection with a loan.


      A Fund will enter into securities lending transactions only with Qualified
Institutions. A Fund will comply with the following conditions whenever it lends
securities: (i) the Fund must receive at least 100% cash collateral or
equivalent securities from the borrower; (ii) the value of the loan is "marked
to market" on a daily basis; (iii) the Fund must be able to terminate the loan
at any time; (iv) the Fund must receive reasonable interest on the loan, as well
as any dividends, interest or other distributions on the loaned securities and
any increase in market value; (v) the Fund may pay only reasonable custodian
fees in connection with the loan; and (vi) voting rights on the loaned
securities may pass to the borrower except that, if a material event adversely
affecting the investment in the loaned securities occurs, the Fund must
terminate the loan and regain the right to vote the securities. A Fund may pay
reasonable finders', administrative and custodial fees in connection with a loan
of its securities. In these transactions, there are risks of delay in recovery
and in some cases even of loss of rights in the collateral should the borrower
of the securities fail financially.

      BORROWING


      Each Fund may borrow up to 20% of the value of its total assets
(calculated when the loan is made) from banks to take advantage of investment
opportunities, for temporary, extraordinary or emergency purposes or for the
clearance of transactions. Each Fund may pledge up to 20% of its total assets to
secure these borrowings. If a Fund's asset coverage for borrowings falls below
300%, the Fund will take prompt action to reduce its borrowings. If a Fund
borrows to invest in securities, any investment gains made on the securities in
excess of interest paid on the borrowing will cause the net asset value of the
shares to rise faster than would otherwise be the case. On the other hand, if
the investment performance of the additional securities purchased fails to cover
their cost (including any interest paid on the money borrowed) to the Fund, the
net asset value of the Fund's shares will decrease faster than would otherwise
be the case. This is the speculative factor known as "leverage."



      Each Fund may borrow from time to time, at the Subadviser's discretion, to
take advantage of investment opportunities, when yields on available investments
exceed interest rates and other expenses of related borrowing, or when, in the
Subadviser's opinion, unusual market conditions otherwise make it advantageous
for the Fund to increase its investment capacity. A Fund will only borrow when
there is an expectation that it will benefit the Fund after taking into account
considerations such as interest income and possible losses upon liquidation.
Borrowing by a Fund creates an opportunity for increased net income but, at the
same time, creates risks, including the fact that leverage may exaggerate
changes in the net asset value of Fund shares and in the yield on the Fund. A
Fund may also borrow for temporary, extraordinary or emergency purposes and for
the clearance of transactions. A Fund may borrow through forward rolls, dollar
rolls or reverse repurchase agreements, although no Fund other than Prudential
Bond Market Index Fund currently has any intention of doing so. Prudential Bond
Market Index Fund may use dollar rolls as described in its Prospectus.



      DOLLAR ROLLS



      Prudential Bond Market Index Fund may use dollar rolls as part of its
investment strategy. The Fund may enter into dollar rolls in which the Fund
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 Fund
forgoes principal and interest paid on the securities. The Fund 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.



      Dollar rolls involve the risk that the market value of the securities
retained by the Fund may decline below the price of the securities the Fund has
sold but is obligated to repurchase under the agreement. Dollar rolls are
speculative techniques involving leverage and are considered borrowings by the
Fund, which are limited to 20% of the Fund's total assets. The Fund may cover
dollar rolls by segregating with its custodian cash or liquid assets equal in
value to its obligations for dollar rolls. Covered rolls (I.E., those for which
there is an offsetting cash position or a cash equivalent security position) are
not considered borrowings for the purposes of the 20% limitation.


      SECURITIES OF FOREIGN ISSUERS


      PRUDENTIAL EUROPE INDEX FUND AND PRUDENTIAL PACIFIC INDEX FUND WILL INVEST
PRIMARILY IN EQUITY SECURITIES OF FOREIGN COMPANIES. PRUDENTIAL STOCK INDEX FUND
MAY INVEST A PORTION OF ITS ASSETS IN EQUITY SECURITIES OF FOREIGN ISSUERS
DENOMINATED IN U.S. CURRENCY. FOREIGN SECURITIES INVOLVE CERTAIN RISKS WHICH
SHOULD BE CONSIDERED CAREFULLY BY AN INVESTOR IN THESE FUNDS. THESE RISKS
INCLUDE POLITICAL OR ECONOMIC INSTABILITY IN THE COUNTRY OF THE ISSUER, THE
DIFFICULTY OF PREDICTING INTERNATIONAL TRADE PATTERNS, THE POSSIBILITY OF
IMPOSITION OF EXCHANGE CONTROLS AND THE RISK OF CURRENCY FLUCTUATIONS. Foreign
securities may be subject to greater fluctuations in price than securities
issued by U.S. corporations or issued or guaranteed by the U.S. Government, its
instrumentalities or agencies. In addition, there may be less publicly available
information about a foreign company than about a domestic company. Foreign
companies generally are not subject to uniform accounting, auditing and
financial reporting standards comparable to those applicable to domestic
companies. There is generally less government regulation of securities
exchanges, brokers and listed companies abroad than in the United States and,
with respect to certain foreign countries, there is a possibility of
expropriation, confiscatory taxation or diplomatic developments which could
affect investment in those countries.



                                      B-12
<PAGE>


      IF A SECURITY IS DENOMINATED IN A FOREIGN CURRENCY, IT WILL BE AFFECTED BY
CHANGES IN CURRENCY EXCHANGE RATES AND IN EXCHANGE CONTROL REGULATIONS, AND
COSTS WILL BE INCURRED IN CONNECTION WITH CONVERSIONS BETWEEN CURRENCIES. A
change in the value of any such currency against the U.S. dollar will result in
a corresponding change in the U.S. dollar value of a Fund's securities
denominated in that currency. Such changes also will affect the Fund's income
and distributions to shareholders. In addition, although Prudential Europe Index
Fund and Prudential Pacific Index Fund will receive income in foreign
currencies, the two Funds will be required to compute and distribute their
income in U.S. dollars. Therefore, if the exchange rate for any such currency
declines after the Funds' income has been accrued and translated into U.S.
dollars, the Funds could be required to liquidate portfolio securities to make
such distributions, particularly in instances in which the amount of income the
Funds are required to distribute is not immediately reduced by the decline in
such currency. Similarly, if an exchange rate declines between the time a Fund
incurs expenses in U.S. dollars and the time such expenses are paid, the amount
of such currency required to be converted into U.S. dollars in order to pay such
expenses in U.S. dollars will be greater than the equivalent amount in any such
currency of such expenses at the time they were incurred. Prudential Europe
Index Fund and Prudential Pacific Index Fund may, but need not, enter into
futures contracts on foreign currencies, foreign currency forward contracts and
options on foreign currencies for hedging purposes, including, locking-in the
U.S. dollar price of the purchase or sale of securities denominated in a foreign
currency; locking-in the U.S. dollar equivalent of interest or dividends to be
paid on such securities which are held by the Fund; and protecting the U.S.
dollar value of such securities which are held by the Fund.



      The Funds (other than Prudential Bond Market Index Fund) may invest a
portion of their assets in equity securities of foreign issuers denominated in
U.S. currency. ADRs and ADSs are not deemed to be foreign securities.


      The value of a Fund's foreign investments may be significantly affected by
changes in currency exchange rates. The dollar value of a foreign security
generally decreases when the value of the dollar rises against the foreign
currency in which the security is denominated and tends to increase when the
value of the dollar falls against such currency. In addition, the value of the
Fund's assets may be affected by losses and other expenses incurred in
converting between various currencies in order to purchase and sell foreign
securities and by currency restrictions and exchange control regulation.

      The economies of many of the countries in which a Fund may invest are not
as developed as the economy of the U.S. and may be subject to significantly
different forces. Political or social instability, expropriation or confiscatory
taxation, and limitations on the removal of funds or other assets, could also
adversely affect the value of investments.

      Foreign companies are generally not subject to the regulatory controls
imposed on U.S. issuers and, in general, there is less publicly available
information about foreign securities than is available about domestic
securities. Many foreign companies are not subject to uniform accounting,
auditing and financial reporting standards, practices and requirements
comparable to those applicable to domestic companies. Income from foreign
securities owned by a Fund may be reduced by a withholding tax at the source
which would reduce dividend income payable to shareholders.

      Brokerage commission rates in foreign countries are likely to be higher.
The securities markets in many of the countries in which a Fund may invest will
have substantially less trading volume than the principal U.S. markets. As a
result, the securities of some companies in these countries may be less liquid
and more volatile than comparable U.S. securities. There is generally less
government regulation and supervision of foreign stock exchanges, brokers and
issuers which may make it difficult to enforce contractual obligations.


      RISK FACTORS AND SPECIAL CONSIDERATIONS OF INVESTING IN EURO-DENOMINATED
SECURITIES. On January 1, 1999, 11 of the 15 member states of the European
Monetary Union introduced the "euro" as a common currency. During a three-year
transitional period, the euro will coexist with each participating state's
currency and, on July 1, 2002, the euro is expected to become the sole currency
of the participating states. During the transition period, the Fund will treat
the euro as a separate currency from that of any participating state.



      The conversion may adversely effect a Fund if the euro does not take
effect as planned; if a participating state withdraws from the European Monetary
Union; or if the computing, accounting and trading systems used by the Fund's
service providers, or by entities with which the Fund or its service providers
do business, are not capable of



                                      B-13
<PAGE>


recognizing the euro as a distinct currency at the time of, and following, euro
conversion. In addition, the conversion could cause markets to become more
volatile.



      The overall effect of the transition of member states' currencies to the
euro is not known at this time. It is likely that more general short- and
long-term ramifications can be expected, such as changes in the economic
environment and change in the behavior of investors, which would affect the
Fund's investments and its net asset value. In addition, although U.S. Treasury
regulations generally provide that the euro conversion will not, in itself,
cause a U.S. taxpayer to realize gain or loss, other changes that may occur at
the time of the conversion, such as accrual periods, holiday conventions,
indexes, and other features may require the realization of a gain or loss by the
Fund as determined under existing law.



      The Funds, Manager has taken steps: (1) that it believes will reasonably
address euro-related changes to enable each Fund and its service providers to
process transactions accurately and completely with minimal disruption to
business activities and (2) to obtain reasonable assurances that appropriate
steps have been taken by the Fund's other service providers to address the
conversion. No Fund has borne any expense relating to these actions.



      HEDGING AND RETURN ENHANCEMENT STRATEGIES



      The Funds may also engage in various portfolio strategies to reduce
certain risks of their investments and to attempt to enhance return. A Fund, and
thus its investors, may lose money through any unsuccessful use of these
strategies. These strategies currently include the use of derivatives, such as
options, futures contracts and options thereon. A Fund'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. See "Investment Objectives and Policies" and "Taxes, Dividends and
Distributions" in the Statement of Additional Information. New financial
products and risk management techniques continue to be developed, and each Fund
may use these new investments and techniques to the extent consistent with its
investment objective and policies.



      OPTIONS TRANSACTIONS



      Each Fund may purchase and write (I.E., sell) put and call options on any
security in which it may invest or options on any securities index. These
options are traded on U.S. exchanges or in the over-the-counter market to hedge
a Fund's portfolio. Prudential Europe Index Fund and Prudential Pacific Index
Fund also may purchase and write put and call options on currencies. Each Fund
may write covered put and call options to generate additional income through the
receipt of premiums and purchase call options in an effort to protect against an
increase in the price of securities (or currencies) it intends to purchase. Each
Fund may also purchase put and call options to offset previously written put and
call options of the same series. See "Investment Objectives and
Policies--Investment Policies Applicable to Each of the Funds--Options on
Securities and Securities Indices" in the Statement of Additional Information.



      A call option gives the purchaser, in exchange for a premium paid, the
right for a specified period of time to purchase the security, currency or
securities in the index subject to the option at a specified price (the exercise
price or strike price). The writer of a call option, in return for the premium,
has the obligation, upon exercise of the option, to deliver, depending upon the
terms of the option contract, the underlying securities or a specified amount of
cash to the purchaser upon receipt of the exercise price. When a Fund writes a
call option, it gives up the potential for gain on the underlying securities in
excess of the exercise price of the option during the period that the option is
open.



      A put option gives the purchaser, in return for a premium, the right, far
a specified period of time, to sell the securities or currency subject to the
option to the writer of the put at the specified exercise price. The writer of
the put option, in return for the premium, has the obligation, upon exercise of
the option, to acquire the securities or currency underlying the option at the
exercise price. A Fund might, therefore, be obligated to purchase the underlying
securities or currency for more than the current market price.



      Each Fund will write only "covered" options. A written option is covered
if, as long as a Fund is obligated under the option, it (i) owns an offsetting
position in the underlying security or (ii) segregates cash or other liquid
assets in an amount equal to or greater than its obligation under the option.
Under the first circumstance, a Fund's losses



                                      B-14
<PAGE>


are limited because it owns the underlying position; under the second
circumstance, in the case of a written call option, a Fund's losses are
potentially unlimited. There is no limitation on the amount of call options the
Fund may write.



      Each Fund may also write a call option, which can serve as a limited short
hedge because decreases in value of the hedged investment would be offset to the
extent of the premium received for writing the option. However, if the security
appreciates to a price higher than the exercise price of the call option, it can
be expected that the option will be exercised and the Fund will be obligated to
sell the security at less than its market value.



      Each Fund may purchase and sell put and call options on securities
indices. Securities index options are designed to reflect price fluctuations in
a group of securities or segment of the securities market rather than price
fluctuations in a single security. Options on securities indices are similar to
options on securities, except that the exercise of securities index options
requires cash payments and does not involve the actual purchase or sale of
securities. When purchasing or selling securities index options, each Fund is
subject to the risk that the value of its portfolio securities may not change as
much as or more than the index because the Fund's investments generally will not
match the composition of the index.



      OPTIONS ON SECURITIES AND SECURITIES INDEXES


      A number of risk factors are associated with options transactions. There
is no assurance that a liquid secondary market on an options exchange will exist
for any particular option, at any particular time. If a Fund is unable to effect
a closing purchase transaction with respect to covered options it has written, a
Fund will not be able to sell the underlying securities or dispose of assets
segregated until the options expire or are exercised. Similarly, if a Fund is
unable to effect a closing sale transaction with respect to options it has
purchased, it would have to exercise the options in order to realize any profit
and may incur transaction costs upon the purchase or sale of underlying
securities. The ability to terminate over-the-counter (OTC) option positions is
more limited than the ability to terminate exchange-traded option positions
because a Fund would have to negotiate directly with a counterparty. In
addition, with OTC options, there is a risk that the counterparty in such
transactions will not fulfill its obligations.

      A Fund pays brokerage commissions or spreads in connection with its
options transactions, as well as for purchases and sales of underlying
securities. The writing of options could result in significant increases in a
Fund's turnover rate.

      The risks of investment in index options may be greater than options on
securities. Because index options are settled in cash, when a Fund writes a call
option on an index it cannot provide in advance for its potential settlement
obligations by acquiring and holding the underlying securities. A Fund can
offset some of the risk of writing a call index option position by holding a
diversified portfolio of securities similar to those on which the underlying
index is based. However, the Fund cannot, as a practical matter, acquire and
hold a portfolio containing exactly the same securities as underlie the index
and, as a result, bears a risk that the value of the securities held will vary
from the value of the index.

      Even if a Fund could assemble a securities portfolio that exactly
reproduced the composition of the underlying index, it still would not be fully
covered from a risk standpoint because of the "timing risk" inherent in writing
index options. When an index option is exercised, the amount of cash that the
holder is entitled to receive is determined by the difference between the
exercise price and the closing index level on the date when the option is
exercised. As with other kinds of options, the Fund as the call writer will not
know that it has been assigned until the next business day at the earliest. The
time lag between exercise and notice of assignment poses no risk for the writer
of a covered call on a specific underlying security, such as a common stock,
because there the writer's obligation is to deliver the underlying security, not
to pay its value as of a fixed time in the past. So long as the writer already
owns the underlying security, it can satisfy its settlement obligations by
simply delivering it, and the risk that its value may have declined since the
exercise date is borne by the exercising holder. In contrast, even if the writer
of an index call holds securities that exactly match the composition of the
underlying index, it will not be able to satisfy its assignment obligations by
delivering those securities against payment of the exercise price. Instead, it
will be required to pay cash in an amount based on the closing index value on
the exercise date; and by the time it learns that it has been assigned, the
index may have declined, with a corresponding decline in the value of its
securities


                                      B-15
<PAGE>

portfolio. This "timing risk" is an inherent limitation on the ability of index
call writers to cover their risk exposure by holding securities positions.

      If a Fund has purchased an index option and exercises it before the
closing index value for that day is available, it runs the risk that the level
of the underlying index may subsequently change. If such a change causes the
exercised option to fall out-of-the-money, the Fund will be required to pay the
difference between the closing index value and the exercise price of the option
(times the applicable multiplier) to the assigned writer.

      A Fund will not purchase put options or call options if, after any such
purchase, the aggregate premiums paid for such options would exceed 20% of the
Fund's net assets. The aggregate value of the obligations underlying put options
will not exceed 25% of a Fund's net assets.

      FUTURES CONTRACTS AND OPTIONS ON FUTURES CONTRACTS


      Each Fund may purchase and sell financial futures contracts and options
thereon which are traded on a commodities exchange or board of trade to reduce
certain risks of its investments and to attempt to enhance return in accordance
with regulations of the Commodity Futures Trading Commission (CFTC). The Funds,
and thus their investors, may lose money through any unsuccessful use of these
strategies. These futures contracts and related options will be on securities
indices. A futures contract is an agreement to purchase or sell an agreed amount
of securities at a set price for delivery in the future. A stock index futures
contract is an agreement to purchase or sell cash equal to a specific dollar
amount times the difference between the value of a specific stock index at the
close of the last trading day of the contract and the price at which the
agreement is made. No physical delivery of the underlying stocks in the index is
made. A Fund may purchase and sell futures contracts or related options as a
hedge against changes in market conditions.



      A Fund may not purchase or sell futures contracts and related options to
attempt to enhance return, if immediately thereafter the sum of the amount of
initial margin deposits on the Fund's existing futures and options on futures
and premiums paid for such related options would exceed 5% of the market value
of the Fund's total assets. A Fund may purchase and sell futures contracts and
related options, without limitation, for BONA FIDE hedging purposes in
accordance with regulations of the CFTC (I.E., to reduce certain risks of its
investments).



      Futures contracts and related options are generally subject to segregation
requirements of the Commission and coverage requirements of the CFTC. If a Fund
does not hold the security underlying the futures contract, the Fund will be
required to segregate on an ongoing basis with its Custodian cash or other
liquid assets in an amount at least equal to the Fund's obligations with respect
to such futures contract.



      A Fund's successful use of futures contracts and related options is
subject to various additional risks. The correlation between movements in the
price of a futures contract and the movements in the index is imperfect and
there is a risk that the value of the indices underlying the futures contract
may increase or decrease at a greater rate than the related futures contracts
resulting in losses to the Fund. Certain futures exchanges or boards of trade
have established daily limits on the amount that the price of futures contracts
or related options may vary, either up or down, from the previous day's
settlement price. These daily limits may restrict each Fund's ability to
purchase or sell certain futures contracts or related options on any particular
day.



      A futures contract on securities or currency is an agreement to buy and
sell securities or currency at a specified price at a designated date. Futures
contracts and options thereon may be entered into for hedging purposes and for
the other purposes described in each Prospectus. A Fund may enter into futures
contracts in order to hedge against changes in interest rates, stock market
prices or currency exchange rates.


      The purchase of futures or call options thereon can serve as a long hedge,
and the sale of futures or the purchase of put options thereon can serve as a
short hedge. Writing call options on futures contracts can serve as a limited
short hedge, and writing put options on futures contracts can serve as a limited
long hedge.

      No price is paid upon entering into a futures contract. Instead, at the
inception of a futures contract, a Fund is required to deposit "initial margin,"
consisting of cash or U.S. Government securities, in an amount generally equal
to 10% or less of the contract value. Margin must also be deposited when writing
a call or put option on a futures contract, in accordance with applicable
exchange rules. Unlike margin in securities transactions, initial margin does
not represent a borrowing, but rather is in the nature of a performance bond or
good-faith deposit that is returned


                                      B-16
<PAGE>

to the Fund at the termination of the transaction if all contractual obligations
have been satisfied. Under certain circumstances, such as periods of high
volatility, a Fund may be required by an exchange to increase the level of its
initial margin payment.

      Subsequent "variation margin" payments are made to and from the futures
broker daily as the value of the futures position varies, a process known as
"marking to market." Variation margin does not involve borrowing, but rather
represents a daily settlement of a Fund's obligations to or from a futures
broker. When a Fund purchases an option on a future, the premium paid plus
transaction costs are all that is at risk. In contrast, when a Fund purchases or
sells a futures contract or writes a call or put option thereon, it is subject
to daily variation margin calls that could be substantial in the event of
adverse price movements. If the Fund has insufficient cash to meet daily
variation margin requirements, it might need to sell securities at a time when
such sales are disadvantageous.

      Purchasers and sellers of futures contracts and options on futures can
enter into offsetting closing transactions, similar to closing transactions on
options, by selling or purchasing, respectively, an instrument identical to the
instrument purchased or sold. Positions in futures and options on futures may be
closed only on an exchange or board of trade that provides a secondary market.
Each Fund intends to enter into futures and options on futures transactions only
on exchanges or boards of trade where there appears to be a liquid secondary
market. However, there can be no assurance that such a market will exist for a
particular contract at a particular time.


RISKS OF HEDGING AND RETURN ENHANCEMENT STRATEGIES



      Participation in the options or futures markets involves investment risks
and transaction costs to which a Fund would not be subject absent the use of
these strategies. A Fund, and thus its investors, may lose money through any
unsuccessful use of these strategies. Risks inherent in the use of options,
futures contracts and options on futures contracts include (1) imperfect
correlation between the price of options and futures contracts and options
thereon and movements in the prices of the securities being hedged; (2) the fact
that skills needed to use these strategies are different from those needed to
select portfolio securities; (3) the possible absence of a liquid secondary
market for any particular instrument at any time; (4) the possible need to defer
closing out certain hedged positions to avoid adverse tax consequences; (5) the
risk that the counter party may be unable to complete the transaction and (6)
the possible inability of a Fund 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
a Fund to sell a portfolio security at a disadvantageous time, due to the need
for the Fund to maintain "cover" or to segregate liquid assets in connection
with hedging transactions. See "Taxes, Dividends and Distributions."



      Each Fund will generally purchase options and futures on an exchange only
if there appears to be a liquid secondary market for such options or futures; a
Fund will generally purchase OTC options only if the investment adviser believes
that the other party to options will continue to make a market for such options.
However, there can be no assurance that a liquid secondary market will continue
to exist or that the other party will continue to make a market. Thus, it may
not be possible to close an options or futures transaction. The inability to
close options and futures positions also could have an adverse impact on a
Fund's ability to effectively hedge its portfolio. There is also the risk of
loss by a Fund of margin deposits or collateral in the event of bankruptcy of a
broker with whom the Fund has an open position in an option, a futures contract
or related option.


      Under certain circumstances, futures exchanges may establish daily limits
on the amount that the price of a future or option on a futures contract can
vary from the previous day's settlement price; once that limit is reached, no
trades may be made that day at a price beyond the limit. Daily price limits do
not limit potential losses because prices could move to the daily limit for
several consecutive days with little or no trading, thereby preventing
liquidation of unfavorable positions.

      If a Fund were unable to liquidate a futures or option on a futures
contract position due to the absence of a liquid secondary market or the
imposition of price limits, it could incur substantial losses. The Fund would
continue to be subject to market risk with respect to the position. In addition,
except in the case of purchased options, the Fund would continue to be required
to make daily variation margin payments and might be required to maintain the
position being hedged by the future or option or to segregate cash or
securities.

      Certain characteristics of the futures market might increase the risk that
movements in the prices of futures contracts or options on futures contracts
might not correlate perfectly with movements in the prices of the


                                      B-17
<PAGE>

investments being hedged. For example, all participants in the futures and
options on futures contracts markets are subject to daily variation margin calls
and might be compelled to liquidate futures or options on futures contract
positions whose prices are moving unfavorably to avoid being subject to further
calls. These liquidations could increase price volatility of the instruments and
distort the normal price relationship between the futures or options and the
investments being hedged. Also, because initial margin deposit requirements in
the futures market are less onerous than margin requirements in the securities
markets, there might be increased participation by speculators in the futures
markets. This participation also might cause temporary price distortions. In
addition, activities of large traders in both the futures and securities markets
involving arbitrage, "program trading" and other investment strategies might
result in temporary price distortions.

      FOREIGN CURRENCY FORWARD CONTRACTS, OPTIONS AND FUTURES TRANSACTIONS

      Prudential Europe Index Fund's and Prudential Pacific Index Fund's
transactions in forward contracts will be limited to hedging involving either
specific transactions or portfolio positions. Transaction hedging is the
purchase or sale of a forward contract with respect to specific receivables or
payables of a Fund generally arising in connection with the purchase or sale of
its securities and accruals of interest or dividends receivable and Fund
expenses. Position hedging is the sale of a foreign currency with respect to
security positions denominated or quoted in that currency. A Fund may not
position hedge with respect to a particular currency for an amount greater than
the aggregate market value (determined at the time of making any sale of a
forward contract) of securities, denominated or quoted in, or currently
convertible into, such currency. A forward contract generally has no deposit
requirements, and no commissions are charged for such trades.

      A Fund may enter into a forward contract to hedge against risk in the
following circumstances: (i) during the time period when the Fund contracts for
the purchase or sale of a security denominated in a foreign currency, or (ii)
when the Fund anticipates the receipt in a foreign currency of dividends or
interest payments on a security which it holds. By entering into a forward
contract for a fixed amount of dollars for the purchase or sale of the amount of
foreign currency involved in the underlying transaction, the Fund will be able
to protect itself against a possible loss resulting from an adverse change in
the relationship between the U.S. dollar and the subject foreign currency during
the period between the date on which the security is purchased or sold, or on
which the dividend or interest payment is declared, and the date on which such
payments are made or received. Additionally, when the Subadviser believes that
the currency of a particular foreign country may suffer a substantial decline
against the U.S. dollar, the Fund may enter into a forward contract, for a fixed
amount of dollars, to sell the amount of foreign currency approximating the
value of some or all of the securities of the Fund denominated in such foreign
currency. Further, the Fund may enter into a forward contract in one foreign
currency, or basket of currencies, to hedge against the decline or increase in
value in another foreign currency. Use of a different currency or basket of
currencies magnifies the risk that movements in the price of the forward
contract will not correlate or will correlate unfavorably with the foreign
currency being hedged.

      Forward currency contracts (i) are traded in an interbank market conducted
directly between currency traders (typically commercial banks or other financial
institutions) and their customers, (ii) generally have no deposit requirements
and (iii) are typically consummated without payment of any commissions. Failure
by the Fund's counterparty to make or take delivery of the underlying currency
at the maturity of the forward contract would result in the loss to the Fund of
any expected benefit of the transaction.

      As is the case with futures contracts, purchasers and sellers of forward
currency contracts can enter into offsetting closing transactions, similar to
closing transactions on futures, by selling or purchasing, respectively, an
instrument identical to the instrument purchased or sold. Secondary markets
generally do not exist for forward currency contracts, with the result that
closing transactions generally can be made for forward currency contracts only
by negotiating directly with the counterparty. Thus, there can be no assurance
that a Fund will in fact be able to close out a forward currency contract at a
favorable price prior to maturity. In addition, in the event of insolvency of
the counterparty, the Fund might be unable to close out a forward currency
contract at any time prior to maturity. In either event, the Fund would continue
to be subject to market risk with respect to the position, and would continue to
be required to maintain a position in the securities or currencies that are the
subject of the hedge or to segregate cash or other liquid assets in an amount
equal to the position. A Fund's ability to enter into foreign currency forward
contracts may be limited by certain requirements for qualification as a
regulated investment company under the Internal Revenue Code. See "Taxes,
Dividends and Distributions."


                                      B-18
<PAGE>

      Prudential Europe Index Fund and Prudential Pacific Index Fund may
purchase and write put and call options on foreign currencies traded on
securities exchanges or boards of trade (foreign and domestic) and OTC options
for hedging purposes in a manner similar to that in which foreign currency
forward contracts and futures contracts on foreign currencies will be employed.
Options on foreign currencies are similar to options on securities, except that
the Fund has the right to take or make delivery of a specified amount of foreign
currency, rather than securities.

      Generally, the OTC foreign currency options used by these Funds are
European-style options. This means that the option is only exercisable
immediately prior to its expiration. This is in contrast to American-style
options, which are exercisable at any time prior to the expiration date of the
option.

      If the Subadviser anticipates purchasing a foreign security and also
anticipates a rise in the value of such foreign currency (thereby increasing the
cost of such security), the Fund may purchase call options or write put options
on the foreign currency. The Fund could also enter into a long forward contract
or a long futures contract on such currency, or purchase a call option, or write
a put option, on a currency futures contract. The use of such instruments could
offset, at least partially, the effects of the adverse movements of the exchange
rates.

      FOREIGN CURRENCY STRATEGIES--SPECIAL CONSIDERATIONS

      Prudential Europe Index Fund and Prudential Pacific Index Fund may use
options on foreign currencies, futures on foreign currencies, options on futures
on foreign currencies and forward currency contracts, to hedge against movements
in the values of the foreign currencies in which the Fund's securities are
denominated. Such currency hedges can protect against price movements in a
security that the Fund owns or intends to acquire that are attributable to
changes in the value of the currency in which it is denominated. Such hedges do
not, however, protect against price movements in the securities that are
attributable to other causes.

      A Fund might seek to hedge against changes in the value of a particular
currency when no futures contract, forward contract or option involving that
currency is available or one of such contracts is more expensive than certain
other contracts. In such cases, the Fund may hedge against price movements in
that currency by entering into a contract on another currency or basket of
currencies, the values of which the Subadviser believes will have a positive
correlation to the value of the currency being hedged. The risk that movements
in the price of the contract will not correlate perfectly with movements in the
price of the currency being hedged is magnified when this strategy is used.

      The value of futures contracts, options on futures contracts, forward
contracts and options on foreign currencies depends on the value of the
underlying currency relative to the U.S. dollar. Because foreign currency
transactions occurring in the interbank market might involve substantially
larger amounts than those involved in the use of futures contracts, forward
contracts or options, a Fund could be disadvantaged by dealing in the odd lot
market (generally consisting of transactions of less than $1 million) for the
underlying foreign currencies at prices that are less favorable than for round
lots.

      There is no systematic reporting of last sale information for foreign
currencies or any regulatory requirements that quotations available through
dealers or other market sources be firm or revised on a timely basis. Quotation
information generally is representative of very large transactions in the
interbank market and thus might not reflect odd-lot transactions where rates
might be less favorable. The interbank market in foreign currencies is a global,
round-the-clock market. To the extent the U.S. options or futures markets are
closed while the markets for the underlying currencies remain open, significant
price and rate movements might take place in the underlying markets that cannot
be reflected in the markets for the futures contracts or options until they
reopen.

      Settlement of futures contracts, forward contracts and options involving
foreign currencies might be required to take place within the country issuing
the underlying currency. Thus, a Fund might be required to accept or make
delivery of the underlying foreign currency in accordance with any U.S. or
foreign regulations regarding the maintenance of foreign banking arrangements by
U.S. residents and might be required to pay any fees, taxes and charges
associated with such delivery assessed in the issuing country.

      COVERED FORWARD CURRENCY CONTRACTS, FUTURES CONTRACTS AND OPTIONS

      Transactions using forward currency contracts, futures contracts and
options (other than options that a Fund has purchased) expose the Fund to an
obligation to another party. No Fund will enter into any such transactions
unless it owns either (1) an offsetting ("covered") position in securities,
currencies, or other options, forward currency contracts or futures contracts,
or (2) liquid assets with a value sufficient at all times to cover its potential
obligations not covered as provided in (1) above. Each Fund will comply with the
Securities and Exchange Commission (Commission) guidelines regarding cover for
these instruments and, if the guidelines so require, segregate cash or liquid
assets with its Custodian in the prescribed amount.

      Assets used as cover or segregated cannot be sold while the position in
the corresponding forward currency contract, futures contract or option is open,
unless they are replaced with similar assets. As a result, the commitment of a
large portion of a Fund's assets to cover or segregation could impede portfolio
management or the Fund's ability to meet redemption requests or other current
obligations.

      SEGREGATED ASSETS

      Each Fund will segregate with its Custodian, State Street Bank and Trust
Company (State Street), cash, U.S. Government securities, equity securities
(including foreign securities), debt securities or other liquid, unencumbered
assets equal in value to its obligations in respect of potentially leveraged
transactions. These include forward contracts, when-issued and delayed delivery
securities, futures contracts, written options and options on futures contracts
(unless otherwise covered). If collateralized or otherwise covered, in
accordance with Commission guidelines, these will not be deemed to be senior
securities. The assets segregated will be marked-to-market daily.

      ILLIQUID SECURITIES


      Each of the Funds may hold 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 in
securities markets either within or outside the United States. Repurchase
agreements subject to demand are deemed to have a maturity equal to the notice
period. Historically, illiquid securities have included securities subject to
contractual or legal restrictions on resale because they have not been
registered under the Securities Act of 1933, as amended (Securities Act),
securities which are otherwise not readily marketable and repurchase agreements
having a maturity of longer than seven days. Securities which have not been
registered under the Securities Act are referred to as private placements or
restricted securities and are purchased directly from the issuer or in the
secondary market. Mutual funds do not typically hold a significant amount of
these restricted or other illiquid securities because of the potential for
delays on resale and uncertainty in valuation. Limitations on resale may have an
adverse effect on the marketability of portfolio securities and a mutual fund
might be unable to dispose of restricted or other illiquid securities promptly
or at reasonable prices and might thereby experience difficulty satisfying
redemptions within seven days. A mutual fund might also have to register such
restricted securities in order to dispose of them resulting in additional
expense and delay. Adverse market conditions could impede such a public offering
of securities.


      In recent years, however, a large institutional market has developed for
certain securities that are not registered under the Securities Act including
repurchase agreements, commercial paper, foreign securities, municipal
securities and corporate bonds and notes. Institutional investors depend on an
efficient institutional market in which the unregistered security can be readily
resold or on an issuer's ability to honor a demand for repayment. The fact that
there are contractual or legal restrictions on resale to the general public or
to certain institutions may not be indicative of the liquidity of such
investments.

      Rule 144A of the Securities Act allows for a broader institutional trading
market for securities otherwise subject to restriction on resale to the general
public. Rule 144A establishes a "safe harbor" from the registration requirements
of the Securities Act for resales of certain securities to qualified
institutional buyers. The investment adviser anticipates that the market for
certain restricted securities such as institutional commercial paper will expand
further as a result of this new regulation and the development of automated
systems for the trading,


                                      B-20
<PAGE>

clearance and settlement of unregistered securities of domestic and foreign
issuers, such as the PORTAL System sponsored by the National Association of
Securities Dealers, Inc. (NASD).


      Restricted securities eligible for resale pursuant to Rule 144A and
privately placed commercial paper for which there is a readily available market
are treated as liquid only when deemed liquid under procedures established by
the Board of Trustees. A Fund's investment in Rule 144A securities could have
the effect of increasing illiquidity to the extent that qualified institutional
Buyers become, for a limited time, uninterested in purchasing Rule 144A
securities. The Subadviser will monitor the liquidity of such restricted
securities, subject to the supervision of the Trustees. In reaching liquidity
decisions, the Subadviser will consider, among other things, the following
factors: (1) the frequency of trades and quotes for the security; (2) the number
of dealers wishing to purchase or sell the security and the number of other
potential purchasers; (3) dealer undertakings to make a market in the security
and (4) the nature of the security and the nature of the marketplace trades (for
example, the time needed to dispose of the security, the method of soliciting
offers and the mechanics of the transfer). In addition, in order for commercial
paper that is issued in reliance on Section 4(2) of the Securities Act to be
considered liquid, (a) it must be rated in one of the two highest rating
categories by at least two NRSROs, or if only one NRSRO rates the securities, by
that NRSRO, or, if unrated, be of comparable quality in the view of the
investment adviser, and (b) it must not be "traded flat" (that is, without
accrued interest) or in default as to principal or interest.



      The staff of the Commission has taken the position that purchased OTC
options and the assets used as "cover" for written OTC options are illiquid
securities unless a Fund and the counterparty have provided for the Fund, at the
Fund's election, to unwind the OTC option. The exercise of such an option would
ordinarily involve the payment by the Fund of an amount designed to reflect the
counterparty's economic loss from an early termination, but does allow the Fund
to treat the securities used as "cover" as liquid. A Fund will also treat
non-U.S. Government IOs and POs as illiquid so long as the staff of the SEC
maintains its position that such securities are illiquid.


      OTHER INVESTMENT TECHNIQUES

      Each Fund may take advantage of opportunities in the area of options and
futures contracts and any other derivative instruments that are not presently
contemplated for use by such Fund or that are not currently available but that
may be developed, to the extent such opportunities are both consistent with its
investment objective and legally permissible for the Fund. Before entering into
such transactions or making any such investment, the Fund will provide
appropriate disclosure in its Prospectus.


      TEMPORARY DEFENSIVE STRATEGY AND SHORT-TERM INVESTMENTS. When conditions
dictate a defensive strategy, or pending investment of proceeds from sales of a
Fund's shares, the Fund may invest in money market instruments, including
commercial paper of domestic or foreign corporations, certificates of deposit,
bankers' acceptances and time obligations of domestic or foreign banks, foreign
government securities and obligations issued or guaranteed by the U.S.
Government, its instrumentalities or its agencies. Investments in foreign
securities 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.



      PORTFOLIO TURNOVER. As a result of the investment policies described
above, a Fund may engage in a substantial number of portfolio transactions, and
a Fund's portfolio turnover rate may exceed 100%, but no Fund's portfolio
turnover rate is expected to exceed 100% except for Prudential Bond Market Index
Fund. The portfolio turnover rate is generally the percentage computed by
dividing the lesser of portfolio purchases or sales (excluding all securities,
including options, whose maturities or expiration date at acquisition were one
year or less) by the monthly average value of the long-term portfolio. High
portfolio turnover (100% or more) involves correspondingly greater brokerage
commissions and other transaction costs, which are borne directly by a Fund. In
addition, high portfolio turnover may also mean that a proportionately greater
amount of distributions to shareholders will be taxed as ordinary income rather
than long-term capital gains compared to investment companies with lower
portfolio turnover. See "Brokerage Allocation and Other Practices" and "Taxes,
Dividends and Distributions."

                             INVESTMENT RESTRICTIONS


      The investment restrictions listed below have been adopted by the Company
as fundamental policies of the Funds, except as otherwise indicated. Under the
Investment Company Act of 1940, as amended (Investment Company Act), a
fundamental policy of a Fund may not be changed without the vote of a majority
of the outstanding voting securities of the Fund. As defined in the Investment
Company Act, a "majority of a Fund's outstanding voting securities" means the
lesser of (1) 67% of the shares represented at a meeting at which more than 50%
of the outstanding shares are present in person or represented by proxy or (2)
more than 50% of the outstanding shares.


      A Fund may not:

      1. Purchase any security if, as a result, with respect to 75% of the
Fund's total assets, more than 5% of the value of its total assets (determined
at the time of investment) would then be invested in the securities of any one
issuer.

      2. Purchase a security if more than 10% of the outstanding voting
securities of any one issuer would be held by the Fund.

      3. Purchase a security if, as a result, 25% or more of the value of its
total assets (determined at the time of investment) would be invested in
securities of one or more issuers having their principal business activities in
the same industry. This restriction does not apply to obligations issued or
guaranteed by the United States Government, its agencies or instrumentalities.

      4. Purchase or sell real estate or interests therein (including limited
partnership interests), although a Fund may purchase securities of issuers which
engage in real estate operations and securities which are secured by real estate
or interests therein.

      5. Purchase or sell commodities or commodity futures contracts, except
that a Fund may purchase and sell financial futures contracts and options
thereon and that forward contracts are not deemed to be commodities or commodity
futures contracts.

      6. Purchase oil, gas or other mineral leases, rights or royalty contracts
or exploration or development programs, except that a Fund may invest in the
securities of companies which operate, invest in or sponsor such programs.

      7. Issue senior securities, borrow money or pledge its assets, except that
each Fund may borrow from banks or through forward rolls, dollar rolls or
reverse repurchase agreements up to 20% of the value of its total assets to take
advantage of investment opportunities, 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. For purposes of this
restriction, the purchase or sale of securities on a "when-issued" or delayed
delivery basis; the purchase and sale of options, financial futures contracts
and options thereon; the entry into repurchase agreements and collateral and
margin arrangements with respect to any of the foregoing, will not be deemed to
be a pledge of assets nor the issuance of senior securities.

      8. Make loans except by the purchase of fixed-income securities in which a
Fund may invest consistently with its investment objective and policies or by
use of reverse repurchase and repurchase agreements, forward rolls, dollar rolls
and securities lending arrangements.

      9. Make short sales of securities.

      10. Purchase securities on margin, except for such short-term loans as are
necessary for the clearance of purchases of portfolio securities. (For the
purpose of this restriction, the deposit or payment by any Fund of initial or
maintenance margin in connection with financial futures contracts is not
considered the purchase of a security on margin.)

      11. 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. The Fund has no limit with respect to
investments in restricted securities.


                                      B-22
<PAGE>

      Whenever any fundamental investment policy or investment restriction
states a maximum percentage of a Fund'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 a Fund's asset
coverage for borrowings falls below 300%, the Fund will take prompt action to
reduce its borrowings, as required by applicable law.

(1)   Unless otherwise stated, the address of the Trustees and Officers is c/o
      Prudential Investments Fund Management LLC, Gateway Center Three, 100
      Mulberry Street, Newark, New Jersey 07102-4077.

*     "Interested" Trustee, as defined in the Investment Company Act, by reason
      of his affiliation with Prudential, PIFM or Prudential Securities.


      The Company has Trustees who, in addition to overseeing the actions of the
Funds' Manager, Subadviser and Distributor, decide upon matters of general
policy. The Trustees also review the actions of the Company's officers, who
conduct and supervise the daily business operations of the Funds.



      The Trustees have adopted a retirement policy which calls for the
retirement of Trustees on December 31 of the year in which they reach the age of
72, except that retirement is being phased in for Trustees who were age 68 or
older as of December 31, 1993. Under this phase-in provision, Mr. Beach is
scheduled to retire on December 31, 1999.



      Pursuant to the terms of each Management Agreement with the Funds, the
Manager pays all compensation of officers and employees of the Funds as well as
the fees and expenses of all Trustees of the Funds who are affiliated persons of
the Manager. The Company currently pays each of its Trustees who is not an
affiliated person of The Manager or the investment adviser annual compensation
of $4,000 in addition to certain out-of-pocket expenses. The amount of annual
compensation paid to each Trustee may change as a result of the introduction of
additional funds on whose boards the Trustee may be asked to serve.


      Trustees may receive their Trustees' fees pursuant to a deferred fee
agreement with the Company. Under the terms of the agreement, the Company
accrues daily the amount of such Trustees' fee which accrue 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 Commission exemptive
order, at the daily rate of return of the Company. Payment of the interest so
accrued is also deferred and accruals become payable at the option of the
Trustee. The Company's obligation to make payments of deferred Trustees' fees,
together with interest thereon, is a general obligation of the Company.


      The interested Trustees serve without compensation. The following table
sets forth the aggregate compensation paid by the Company to the Trustees who
were not affiliated with the Manager for the fiscal year ended September 30,
1998 and the aggregate compensation paid to such Trustees for service on the
Company's Board and that of all other funds managed by Prudential Investments
Fund Management LLC (Fund Complex) for the year ended December 31, 1998.

                     INVESTMENT ADVISORY AND OTHER SERVICES



      (A) MANAGER AND INVESTMENT ADVISER. The manager of each Fund is Prudential
Investments Fund Management LLC (formerly Prudential Mutual Fund Management LLC)
(PIFM or the Manager), Gateway Center Three, 100 Mulberry Street, Newark, New
Jersey 07102-4077. PIFM serves as manager to all of the other investment
companies that, together with the Funds, comprise the Prudential Mutual Funds.
See "How the Funds are Managed--Manager" in the Prospectus. As of April 30,
1999, PIFM managed and/or administered open-end and closed-end management
investment companies with assets of approximately      billion. According to the
Investment Company Institute, as of December 31, 1998, the Prudential Mutual
Funds were the 18th largest family of mutual funds in the United States.


      PIFM is a subsidiary of Prudential Securities and The Prudential Insurance
Company of America (Prudential). Prudential Mutual Fund Services LLC (PMFS or
the Transfer Agent), a wholly owned subsidiary of PIFM, serves as the transfer
agent for the Prudential Mutual Funds and, in addition, provides customer
service, recordkeeping and management and administration services to qualified
plans.


      Pursuant to two Management Agreements with the Company (each a Management
Agreement and collectively, the Management Agreements), PIFM, subject to the
supervision of the Company's Board of Trustees and in conformity with the stated
policies of each Fund, manages both the investment operations of each Fund and
the composition of each Fund's portfolio, including the purchase, retention,
disposition and loan of securities. In connection therewith, PIFM is obligated
to keep certain books and records of the Company. PIFM also administers the
Company's business affairs and, in connection therewith, furnishes the Company
with office facilities, together with those ordinary clerical and bookkeeping
services which are not being furnished by State Street Bank and Trust Company,
the Funds' custodian (the Custodian), and PMFS, the Funds' transfer and dividend
disbursing agent. The management services of PIFM for the Funds are not
exclusive under the terms of the Management Agreements and PIFM is free to, and
does, render management services to others.


      For its services, PIFM receives, pursuant to the Management Agreements, a
fee at an annual rate of .25 of 1% of Prudential Bond Market Index Fund's
average daily net assets, .40 of 1% of Prudential Europe Index Fund's average
daily net assets, .40 of 1% of Prudential Pacific Index Fund's average daily net
assets, .30 of 1% of Prudential Small-Cap Index Fund's average daily net assets
and .30 of 1% of Prudential Stock Index Fund's average daily net assets. The fee
is computed daily and payable monthly. Each Management Agreement also provides
that, in the event the expenses of a Fund (including the fees of PIFM, 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 Fund's
shares are qualified for offer and sale, the compensation due to PIFM will be
reduced by the amount of such excess. No jurisdiction currently limits the
Funds' expenses.

      In connection with its management of the business affairs of the Company,
the Manager bears the following expenses:


      (a) the salaries and expenses of all of its and the Company's personnel
except the fees and expenses of Trustees who are not affiliated persons of the
Manager or the Funds' Subadviser;



      (b) all expenses incurred by the Manager or by the Company in connection
with managing the ordinary course of the Company's business, other than those
assumed by the Company as described below; and



      (c) the costs and expenses or fees payable to The Prudential Investment
Corporation, doing business as Prudential Investments (PI, the investment
adviser or the Subadviser), pursuant to two subadvisory agreements between the
Manager and the Subadviser (collectively, the Subadvisory Agreements).



      Under the terms of the Management Agreements, the Company is responsible
for the payment of the following expenses: (i) the fees payable to the Manager,
(ii) the fees and expenses of Trustees who are not affiliated persons of the
Manager or the Funds' Subadviser, (iii) the fees and certain expenses of the
Custodian and Transfer Agent, including the cost of providing records to the
Manager in connection with its obligation of maintaining required records of the
Company, pricing the Funds' shares and the cashiering function, (iv) the charges
and expenses of legal counsel and independent accountants for the Company, (v)
brokerage commissions and any issue or transfer



                                      B-27
<PAGE>

taxes chargeable to the Company in connection with its securities and futures
transactions, (vi) all taxes and corporate fees payable by the Company to
governmental agencies, (vii) the fees of any trade associations of which the
Company may be a member, (viii) the cost of stock certificates representing
shares of Funds of the Company, if any, (ix) the cost of fidelity and liability
insurance, (x) the fees and expenses involved in registering and maintaining
registration of the Company and of its shares with the Commission, including the
preparation and printing of the Company's registration statements and
prospectuses for such purposes, and paying the fees and expenses of notice
filings made in accordance with state securities laws, (xi) licensing fees, if
any, (xii) allocable communications expenses with respect to investor services
and all expenses of shareholders' and Trustees' meetings and of preparing,
printing and mailing reports, proxy statements and prospectuses to shareholders
in the amount necessary for distribution to the shareholders and (xiii)
litigation and indemnification expenses and other extraordinary expenses not
incurred in the ordinary course of the Company's business.


      The Management Agreements provide that PIFM will not be liable for any
error of judgment or for any loss suffered by the Company in connection with the
matters to which the Management Agreements relate, except a loss resulting from
willful misfeasance, bad faith, gross negligence or reckless disregard of duty.
Each 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. Each 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.



      Prudential Institutional Fund Management, Inc., the manager of Prudential
Stock Index Fund until October 30, 1996, received for the period from September
30, 1996 through October 30, 1996, and for the fiscal year ended September 30,
1996, the following management fees from the Fund, expressed both as a dollar
amount and as a percentage of the Fund's average daily net assets: $64,568
(.40%), $570,160 (.40%), respectively. For the period from October 30, 1996
through September 30, 1997, PIFM received the following management fee,
expressed as both a dollar amount and as an annualized percentage of the Fund's
average daily net assets: $921,557 (.30%). During this period the Manager
subsidized certain expenses of the Fund.


      For the fiscal period ended September 30, 1997, PIFM received management
fees of $1,630 from Prudential Pacific Index Fund.

Europe Index Fund, $79,309 from Prudential Pacific Index Fund, $67,841 from
Prudential Small-Cap Index Fund, and $2,457,979 from Prudential Stock Index
Fund.


      The Manager has entered into two Subadvisory Agreements with the
Subadviser. The Subadvisory Agreements provide that the Subadviser furnish
investment advisory services in connection with the management of the Funds. The
Subadviser is reimbursed by the Manager for the reasonable costs and expenses
incurred in furnishing its services. In connection therewith, the Subadviser
subject to the supervision of PIFM is obligated to keep certain books and
records of the Funds. The Subadviser determines what securities and other
instruments are purchased and sold for the Funds and is responsible for
obtaining and evaluating financial data relevant to the Funds. PIFM continues to
have responsibility for all investment advisory services to all the Funds
pursuant to the Management Agreements and supervises the Subadviser's
performance of such services.



      Each 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 Agreements. Each Subadvisory Agreement may be
terminated by the Company, the Manager or the Subadviser upon not more than 60
days', nor less than 30 days', written notice. Each 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.



      (B) PRINCIPAL UNDERWRITER, DISTRIBUTOR AND RULE 12B-1 PLANS. Prudential
Investment Management Services LLC (the Distributor), Gateway Center Three, 100
Mulberry Street, Newark, New Jersey 07102-4077, acts as the distributor of the
Class Z shares of Prudential Bond Market Index Fund, Prudential Europe Index
Fund, Prudential Pacific Index Fund and Prudential Small-Cap Index Fund, and the
Class Z and Class I shares of Prudential Stock



                                      B-28
<PAGE>


Index Fund. Effective October   , 1999, PIMS also acts as the distributor of the
Class A, Class B and Class C shares of Prudential Stock Index Fund. PIMS is a
subsidiary of Prudential.



      The Distributor of the Funds incurs the expenses of distributing the Class
Z and Class I shares under a Distribution Agreement with the Company, none of
which are reimbursed by or paid for by the Funds.



      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
Prudential Stock Index Fund under Rule 12b-1 under the Investment Company Act,
the Distributor incurs the expenses of distributing the Fund's Class A, Class B
and Class C shares.



      The expenses incurred under the Plans include commissions and account
servicing fees paid to, or on account of, brokers or financial institutions
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 the Distributor associated with the sale of
Prudential Stock Index Fund shares, including lease, utility, communications and
sales promotion expenses.



      Under the Plans, the Fund 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 Fund 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.



      The distribution and/or service fees may also be used by the Distributor
to compensate on a continuing basis brokers in consideration for the
distribution, marketing, administrative and other services and activities
provided by brokers with respect to the promotion of the sale of Prudential
Stock Index Fund's shares and the maintenance of related shareholder accounts.



      CLASS A PLAN. Under the Class A Plan, the Fund may pay the Distributor for
its distribution-related expenses 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 (1) 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 (2) 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. The Distributor has
contractually agreed to limit its distribution-related fees payable under the
Class A Plan of .25 of 1% of the average daily net assets of the Class A shares
for the fiscal year ending September 30, 2000.



      CLASS B PLAN AND CLASS C PLANS. Under the Class B and Class C Plans,
Prudential Stock Index Fund pays the Distributor for its distribution-related
expenses 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 the Distributor of (1) 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, respectively, and (2) a service fee of .25% of
1% of the average daily net assets of each of Class B and Class C shares. The
service fee is used to pay for personal service and/or the maintenance of
shareholder accounts. The Distributor also receives contingent deferred sales
charges from certain redeeming shareholders and, with respect to Class C shares,
an initial sales charge.



      Distribution expenses attributable to the sale of Class A, Class B or
Class C shares of Prudential Stock Index Fund will be allocated to each such
class based upon the ratio of sales of each such class to the sales of Class A,
Class B and Class C shares of the Fund 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.



      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 Trustees, including a majority of the Trustees who are not
interested persons of the Company and who have no direct or indirect financial
interest in the Class A, Class B and Class C Plan or in any agreement related to
the Plans (the Rule 12b-1 Trustees), cast in person at a meeting called for the
purpose of voting on such continuance. A Plan may be terminated at any time,
without penalty, by the vote of a majority of the Rule 12b-1 Trustees or by the
vote of the holders of a majority of the outstanding shares of the applicable
class of the Fund on not more than 60 days', nor less than 30 days', written
notice to any other party to the Plan.



                                      B-29
<PAGE>


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 Trustees in the manner described
above. Each Plan will automatically terminate in the event of its 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 Trustees will review at least quarterly a
written report of the distribution expenses incurred on behalf of each class of
shares of Prudential Stock Index Fund by the Distributor. The report includes 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 the Rule 12b-1 Trustees shall be committed to the Rule 12b-1 Trustees.



      Pursuant to the Distribution Agreement, the Company has agreed to
indemnify the Distributor to the extent permitted by applicable law against
certain liabilities under the federal securities laws.



      In addition to distribution and service fees paid by Prudential Stock
Index Fund under the Class A, Class B and Class C Plans, the Manager (or one of
its affiliates) may make payments to dealers (including Prudential Securities)
and other persons who distribute shares of the Fund (including Class Z shares).
Such payments may be calculated by reference to the net asset value of shares
sold by such persons or otherwise.



FEE WAIVERS/SUBSIDIES



      PIFM may from time to time waive all or a portion of its management fee
and subsidize all or a portion of the operating expenses of a Fund. In addition,
the Distributor has contractually agreed to waive a portion of its distribution
fees for the Class A shares as described above. Fee waivers and subsidies will
increase a Fund's total return.



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. 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 of a Fund may not exceed .75 of
1% per class. The 6.25% limitation applies to each class of a Fund rather than
on a per shareholder basis. If aggregate sales charges were to exceed 6.25% of
total gross sales of any class, all sales charges on shares of that class would
be suspended.



      (C) OTHER SERVICE PROVIDERS. State Street Bank and Trust Company, One
Heritage Drive, North Quincy, Massachusetts 02171, serves as Custodian for the
portfolio securities of each Fund and cash and in that capacity maintains

account of $.20. PMFS is also reimbursed for its out-of-pocket expenses,
including but not limited to postage, stationery, printing, allocable
communication expenses and other costs.

                    BROKERAGE ALLOCATION AND OTHER PRACTICES



      The Manager is responsible for decisions to buy and sell securities and
options on securities and futures for a Fund, the selection of brokers, dealers
and futures commission merchants to effect the transactions and the negotiation
of brokerage commissions, if any. The term "Manager" as used in this section
includes the Subadviser. Broker-dealers may receive brokerage commissions on
portfolio transactions, including options and the purchase and sale of
underlying securities upon the exercise of options. On foreign securities
exchanges, commissions may be fixed. Orders may be directed to any broker or
futures commission merchant including, to the extent and in the manner permitted
by applicable law, Prudential Securities and its affiliates. Brokerage
commissions on United States securities, options and futures exchanges or boards
of trade are subject to negotiation between the Manager and the broker or
futures commission merchant.



      In the over-the-counter markets, securities 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 and U.S. Government agency securities may be purchased
directly from the issuer, in which case no commissions or discounts are paid. A
Fund will not deal with Prudential Securities in any transaction in which
Prudential Securities (or any affiliate) acts as principal, except in accordance
with rules of the Commission. Thus, it will not deal in the over-the-counter
market with Prudential Securities acting as market maker, and it will not
execute a negotiated trade with Prudential Securities if execution involves
Prudential Securities acting as principal with respect to any part of a Fund's
order.



      In placing orders for portfolio securities of a Fund, the Manager's
overriding objective is to obtain the possible combination of favorable price
and efficient execution. The Manager seeks to effect each transaction at a price
and commission that provides the most favorable total cost or proceeds
reasonably attainable in the circumstances. The factors that the Manager may
consider in selecting a particular broker, dealer or futures commission merchant
(firms) are the Manager's knowledge of negotiated commission rates currently
available and other current transaction costs; the nature of the portfolio
transaction; the size of the transaction; the desired timing of the trade; the
activity existing and expected in the market for the particular transaction;
confidentiality; the execution, clearance and settlement capabilities of the
firms; the availability of research and research related services provided
through such firms; the Manager's knowledge of the financial stability of the
firms; the Manager's knowledge of actual or apparent operational problems of
firms; and the amount of capital, if any, that would be contributed by firms
executing the transaction. Given these factors, a Fund may pay transaction costs
in excess of that which another firm might have charged for effecting the same
transaction.



      When the Manager selects a firm that executes orders or is a party to
portfolio transactions, relevant factors taken into consideration are whether
that firm has furnished research and research products and/or services, such as
research reports, research compilations, statistical and economic data, computer
data bases, quotation equipment and services, research oriented computer
software, hardware and services, reports concerning the performance of accounts,
valuations of securities, investment related periodicals, investment seminars
and other economic services and consultants. Such services are used in
connection with some or all of the Manager's investment activities; some of such
services, obtained in connection with the execution of transactions for one
investment account, may be used in managing other accounts, and not all of these
services may be used in connection with a Fund.



      The Manager maintains an internal allocation procedure to identity those
firms who have provided it with research and research related products and/or
services, and the amount that was provided, and to endeavor to direct sufficient
commissions to them to ensure the continued receipt of those services that the
Manager believes provides a benefit to a Fund and its other clients. The Manager
makes a good faith determination that the research and/or service is reasonable
in light of the type of service provided and the price and execution of the
related portfolio transactions.



      When the Manager deems the purchase or sale of equities to be in the best
interests of a Fund or its other clients, including Prudential, the Manager may,
but is under no obligation to, aggregate the transactions in order to obtain the
most favorable price or lower brokerage commissions and efficient execution. In
such event, allocation



                                      B-31
<PAGE>


of the transactions, as well as the expenses incurred in the transaction, will
be made by the Manager in the manner it considers to be most equitable and
consistent with its fiduciary obligations to its clients.



      The allocation of orders among firms and the commission rates paid are
reviewed periodically by the Company's Trustees. 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 rules of the Commission. This limitation, in the opinion of the
Company, will not significantly affect a Fund's ability to pursue its present
investment objective. However, in the future in other circumstances, a Fund may
be at a disadvantage because of this limitation in comparison to other funds
with similar objectives but not subject to such limitations.



      Subject to the above considerations, Prudential Securities may act as a
securities broker or futures commission merchant for the Funds. In order for
Prudential Securities (or any affiliate) to effect any portfolio transactions
for a 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 firms or futures
commission merchants in connection with comparable transactions involving
similar securities or futures contracts being purchased or sold on an exchange
or board of trade 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 firm or
futures commission merchant in a commensurate arm's-length transaction.
Furthermore, the Trustees of the Company, including a majority of the
non-interested Trustees, have 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. In
accordance with Section 11(a) of the Securities Exchange Act of 1934, as
amended, Prudential Securities may not retain compensation for effecting
transactions on a national securities exchange for a Fund unless the Fund has
expressly authorized the retention of such compensation. Prudential Securities
must furnish to the Company at least annually a statement setting forth the
total amount of all compensation retained by Prudential Securities from
transactions effected for the Funds during the applicable period. Brokerage and
futures transactions with Prudential Securities (or any affiliate) also are
subject to such fiduciary standards as may be imposed upon Prudential Securities
(or such affiliate) by applicable law.



      During the years ended September 30, 1998, 1997 and 1996, the Company paid
no brokerage commissions to Prudential Securities.



      Each Fund is required to disclose its holdings of securities of its
regular brokers and dealers (as defined under Rule 10b-1 of the Investment
Company Act) and their parents at March 31, 1999. As of March 31, 1999, the
Funds held securities of              in the aggregate amount of               .



                CAPITAL SHARES, OTHER SECURITIES AND ORGANIZATION



      The Company is authorized to issue an unlimited number of shares of
beneficial interest, $.001 par value per share, divided into five series. Each
Fund offers one class of shares, except Prudential Stock Index Fund, which
offers five classes, designated Class A, Class B, Class C, Class I and Class Z
shares. Each class of shares represents an interest in the same assets of
Prudential Stock Index Fund and is identical in all respects except that (1)
each class is subject to different sales charges and distribution and/or service
fees (except for Class Z shares, which are not subject to any sales charges and
distribution and/or service fees), which may affect performance, (2) each class
has exclusive voting rights on any matter submitted to shareholders that relates
solely to its arrangement and has separate voting rights on any matter submitted
to shareholders in which the interests of one class differ from the interests of
any other class, (3) each class has a different exchange privilege, (4) only
Class B shares have a conversion feature, (5) Class A, Class I and Class Z
shares are offered exclusively for sale to a limited group of investors and (6)
Class I shares are subject to nominal transfer agency fees and are held in a
single omnibus account. In accordance with the Company's Declaration of Trust,
the Trustees may authorize the creation of additional series and classes within
such series, with such preferences, privileges, limitations and voting and
dividend rights as the Trustees may determine. The voting rights of the
shareholders of a series or class can be modified only by the vote of
shareholders of that series or class.



      Shares of the Company, 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 Company under certain circumstances. Each



                                      B-32
<PAGE>


share of each class is equal as to earnings, assets and voting privileges,
except as noted above, and each class of shares (with the exception of Class Z
shares, which are not subject to any distribution or service fees) bears the
expenses related to the distribution of 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 each Fund
is entitled to its portion of all of the Fund's assets after all debt and
expenses of the Fund 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 and Class I and Class Z shareholders, whose shares are not subject
to any distribution and/or service fees.



      The Company does not intend to hold annual meetings of shareholders unless
otherwise required by law. The Company will not be required to hold meetings of
shareholders unless, for example, the election of Trustees 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 the vote of 10% of
the Company's outstanding shares for the purpose of voting on the removal of one
or more Trustees or to transact any other business.



      Under the Declaration of Trust, the Trustees may authorize the creation of
additional series of shares (the proceeds of which would be invested in
separate, independently managed portfolios with distinct investment objectives
and policies and share purchase, redemption and net asset value procedures) with
such preferences, privileges, limitations and voting and dividend rights as the
Trustees may determine. All consideration received by the Company for shares of
any additional series, and all assets in which such consideration is invested,
would belong to that series (subject only to the rights of creditors of that
series) and would be subject to the liabilities related thereto. Under the
Investment Company Act, shareholders of any additional series of shares would
normally have to approve the adoption of any advisory contract relating to such
series and of any changes in the investment policies related thereto.



      The Trustees have the power to alter the number and the terms of office of
the Trustees, provided that always at least a majority of the Trustees have been
elected by the shareholders of the Fund. The voting rights of shareholders are
not cumulative, so that holders of more than 50 percent of the shares voting
can, if they choose, elect all Trustees being selected, while the holders of the
remaining shares would be unable to elect any Trustees.



                 PURCHASE REDEMPTION AND PRICING OF FUND SHARES



      Shares of Prudential Stock Index Fund may be purchased at a price equal to
the next determined net asset value (NAV) plus a sales charge which, at the
election of the investor, may be imposed either (1) at the time of purchase
(Class C shares) or (2) on a deferred basis (Class B or Class C shares). Class
A, Class I and Class Z shares of the Fund are offered to a limited group of
investors at NAV without any sales charges.



PURCHASE BY WIRE



      For an initial purchase of shares of a Fund by wire, you must complete an
application and telephone PMFS to receive an account number at (800) 225-1825
(toll-free). The following information will be requested: your name, address,
tax identification number, class election (Prudential Stock Index Fund only),
dividend distribution election, amount being wired and wiring bank. Instructions
should then be given by you to your bank to transfer funds by wire to State
Street Bank and Trust Company (State Street), Boston, Massachusetts, Custody and
Shareholder Services Division, Attention: Prudential Index Series Fund,
specifying on the wire the account number assigned by PMFS and your name and
identifying the Fund and, if an investment in Prudential Stock Index Fund, the
class in which you are eligible to invest (Class A, Class B, Class C or Class Z
shares).



      If you arrange for receipt by State Street of federal funds prior to the
calculation of NAV (4:15 P.M., New York Time) on a business day, you may
purchase shares of a Fund as of that day.



      In making a subsequent purchase order by wire, you should wire State
Street directly and should be sure that the wire specifies Prudential Index
Series Fund, Class A, Class B, Class C or Class Z shares (Prudential Stock Index
Fund only) and your name and individual account number. It is not necessary to
call PMFS to make subsequent purchase orders utilizing Federal Funds. The
minimum amount which may be invested by wire is $1,000.

*     Class B and Class C shares of Prudential Stock Index Fund are subject to a
      contingent deferred sales charge on certain redemptions. Class A, B and C
      shares of Prudential Stock Index Fund were not available on March 31,
      1999.



      SELECTING A PURCHASE ALTERNATIVE (PRUDENTIAL STOCK INDEX FUND ONLY)



      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 Prudential Stock Index Fund:



      If you qualify for Class I shares, it is more advantageous to purchase
them than any other class of shares. If you qualify to purchase Class Z shares,
it is more advantageous to purchase them than Class A, Class B or Class C
shares. If you qualify for Class A shares, it is 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.



CLASS A SHARES



      BENEFIT PLANS. Certain group retirement and savings plans may purchase
Class A shares at NAV, if they meet the required minimum for amount of assets,
average account balance or number of eligible employees. For more information
about these requirements, call Prudential at (800) 353-2847.



      OTHER WAIVERS. In addition, Class A shares may be purchased at NAV,
through the Distributor or the Transfer Agent, by:



      o     officers of the Prudential Mutual Funds (including the Company),



      o     employees of the Distributor, Prudential Securities, PIFM and their
            subsidiaries and members of the families of such persons who
            maintain an "employee related" account at Prudential Securities or
            the Transfer Agent,



      o     employees of subadvisers of the Prudential Mutual Funds provided
            that purchases at NAV are permitted by such person's employer,



      o     Prudential, 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,



      o     registered representatives and employees of brokers who have entered
            into a selected dealer agreement with the Distributor provided that
            purchases at NAV are permitted by such person's employer,



                                      B-34
<PAGE>


      o     investors who have a business relationship with a financial adviser
            who joined Prudential Securities from another investment firm,
            provided that (1) the purchase is made within 180 days of the
            commencement of the financial adviser's employment at Prudential
            Securities, or within one year in the case of Benefit Plans, (2) 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% of less) and (3) the financial adviser
            served as the client's broker on the previous purchase,



      o     investors in Individual Retirement Accounts, provided the purchase
            is made in a directed rollover to such Individual Retirement Account
            or with the proceeds of a tax-free rollover of assets from a Benefit
            Plan for which Prudential provides administrative or recordkeeping
            services and further provided that such purchase is made within 60
            days of receipt of the Benefit Plan distribution,



      o     orders placed by broker-dealers, investment advisers or financial
            planners who have entered into an agreement with the Distributor,
            who place trades for their own accounts or the accounts of their
            clients and who charge a management, consulting or other fee for
            their services (for example, mutual fund "wrap" or asset allocation
            programs), and



      o     orders placed by clients of broker-dealers, investment advisers or
            financial planners who place trades for customer accounts if the
            accounts are linked to the master account of such broker-dealer,
            investment adviser or financial planner and the broker-dealer,
            investment adviser or financial planner charges the clients a
            separate fee for its services (for example, mutual fund "supermarket
            programs").



      Class A shares also may be purchased at NAV by members of the Board of
Directors of Prudential.



      Broker-dealers, investment advisers or financial planners sponsoring
fee-based programs (such as mutual fund "wrap" or asset allocation programs and
mutual fund "supermarket" programs) may offer their clients more than one class
of shares in Prudential Stock Index Fund in connection with different pricing
options for their programs. Investors should consider carefully any separate
transaction and other fees charged by these programs in connection with
investing in each available share class before selecting a share class.



      For an investor to purchase Class A shares at NAV, at the time of the sale
either the Transfer Agent must be notified directly by the Investor or the
Distributor must be notified by the broker facilitating the transaction that the
sale qualifies. The sale will be effected subject to confirmation of your
entitlement.



CLASS B SHARES



      The offering price of Class B shares for investors choosing one of the
deferred sales charge alternatives is the NAV next determined following receipt
of an order in proper form by the Transfer Agent, your broker or the
Distributor. Although there is no sales charge imposed at the time of purchase,
redemptions of Class B shares may be subject to a CDSC. See "Sale of
Shares--Contingent Deferred Sales Charge" below.



      The Distributor will pay, from its own resources, sales commissions of up
to 4% of the purchase price of Class B shares to brokers, financial advisers and
other persons who sell Class B shares at the time of sale. This facilitates the
ability of Prudential Stock Index Fund to sell the Class B shares without an
initial sales charge being deducted at the time of purchase. The Distributor
anticipates that it will recoup its advancement of sales commissions from the
combination of the CDSC and the distribution fee.



CLASS C SHARES



      The offering price of Class C shares is the next determined NAV plus a 1%
sales charge. In connection with the sale of Class C shares, the Distributor
will pay, from its own resources, brokers, financial advisers and other persons
which distribute Class C shares a sales commission of up to 2% of the purchase
price at the time of the sale.

      INVESTMENT OF REDEMPTION PROCEEDS FROM OTHER INVESTMENT COMPANIES.
Investors may purchase Class C shares at NAV, without the initial sales charge,
with the proceeds from the redemption of shares of any unaffiliated registered
investment company which were not held through an account with any Prudential
affiliate. Such purchases must be made within 60 days of the redemption.
Investors eligible for this waiver include: (1) investors purchasing shares
through an account at Prudential Securities; (2) investors purchasing shares
through an ADVANTAGE Account or an Investor Account with Prusec; and (3)
investors purchasing shares through other brokers. This waiver is not available
to investors who purchase shares directly from the Transfer Agent. You must
notify the Transfer Agent directly or through your broker if you are entitled to
this waiver and provide the Transfer Agent with such supporting documents as it
may deem appropriate.



CLASS Z SHARES



      BENEFIT PLANS. Certain group retirement plans may purchase Class Z shares
of Prudential Stock Index Fund if they meet the required minimum for amount of
assets, average account balance or number of eligible employees. For more
information about these requirements, call Prudential at (800) 353-2847.



      MUTUAL FUND PROGRAMS. Class Z shares also can be purchased by participants
in any fee-based program or trust program sponsored by Prudential or an
affiliate that includes mutual funds as investment options and Prudential Stock
Index Fund as an available option. Class Z shares also can be purchased by
investors in certain programs sponsored by broker-dealers, investment advisers
and financial planners who have agreements with Prudential Investments Advisory
Group relating to:



      o     Mutual fund "wrap" or asset allocation programs where the sponsor
            places Fund trades, links its clients' accounts to a master account
            in the sponsor's name and charges its clients a management,
            consulting or other fee for its services.



      o     Mutual fund "supermarket" programs where the sponsor links its
            clients' accounts to a master account in the sponsor's name and the
            sponsor charges a fee for its services.



      Broker-dealers, investment advisers or financial planners sponsoring these
mutual fund programs may offer their clients more than one class of shares in
the Fund in connection with different pricing options for their programs.
Investors should consider carefully any separate transaction and other fees
charged by these programs in connection with investing in each available share
class before selecting a share class.



      OTHER TYPES OF INVESTORS. Class Z shares also are available for purchase
by the following categories of investors:



      o     certain participants in the MEDLEY Program (group variable annuity
            contracts) sponsored by Prudential for whom Class Z shares of the
            Prudential mutual funds are an available investment option



      o     current and former Director/Trustees of the Prudential mutual funds
            (including the Company)



      o     Prudential with an investment of $10 million or more



      In connection with the sale of Class Z shares, the Manager, the
Distributor or one of their affiliates may pay brokers, financial advisers and
other persons which distribute shares a finder's fee, from its own resources,
based on a percentage of the net asset value of shares sold by such persons.



SALE OF 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 (in accordance with
procedures established by the Transfer Agent in connection with investors'
accounts) by the Transfer Agent, the Distributor or your broker. In certain
cases, however, redemption proceeds will be reduced by the amount of any
applicable CDSC, as described below. See "Contingent Deferred Sales Charge"
below. If you are redeeming your shares through a broker, your broker must
receive your sell order before the Fund computes its NAV for that day (that is,
4:15 P.M., New York time) in order to receive that day's NAV. Your broker will
be responsible for furnishing all necessary documentation to the Distributor and
may charge you for its services in connection with redeeming shares of the Fund.



                                      B-36
<PAGE>


      If you hold shares of a Fund through Prudential Securities, you must
redeem your shares through Prudential Securities. Please contact 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, the Distributor or
your broker 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 LLC, Attention: Redemption Services, P.O. Box 15010, New
Brunswick, New Jersey 08906-5010, the Distributor or to your broker.



      SIGNATURE GUARANTEE. If the proceeds of the redemption (1) exceed
$100,000, (2) are to be paid to a person other than the record owner, (3) are to
be sent to an address other than the address on the Transfer Agent's records, or
(4) are to be paid to a corporation, partnership, trust or fiduciary, and your
shares are held directly with the Transfer Agent, 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 inquiries 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. In the case of redemptions from a PruArray Plan, if the proceeds of the
redemption are invested in another investment option of the plan in the name of
the record holder and at the same address as reflected in the Transfer Agent's
records, a signature guarantee is not required.



      Payment for shares presented for redemption will be made by check within
seven days after receipt by the Transfer Agent, the Distributor or your broker
of the certificate and/or written request, except as indicated below. If you
hold shares through a broker, payment for shares presented for redemption will
be credited to your account at your broker, unless you indicate otherwise. Such
payment may be postponed or the right of redemption suspended at times (1) when
the New York Stock Exchange is closed for other than customary weekends and
holidays, (2) when trading on such Exchange is restricted, (3) 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 (4) during any other period
when the Commission, by order, so permits; provided that applicable rules and
regulations of the Commission shall govern as to whether the conditions
prescribed in (2), (3) or (4) exist.



      REDEMPTION IN KIND. If the Trustees determine that it would be detrimental
to the best interests of the remaining shareholders of a Fund to make payment
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
Commission. Securities will be readily marketable and will be valued in the same
manner as in a regular redemption. If your shares are redeemed in kind, you
would incur transaction costs in converting the assets in cash. Each 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 NAV of the Fund during any 90-day period for any
one shareholder.



      [INVOLUNTARY REDEMPTION. In order to reduce expenses of the Company, the
Trustees 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 CDSC will be imposed on any such
involuntary redemption.]



      90-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 Prudential Stock Index Fund
at the NAV next determined after the order is received, which must be within 90
days after the date of the redemption. Any CDSC paid in connection with such
redemption will be credited (in shares) to your account. (If less than a full
repurchase is made, the credit will be on a PRO RATA basis.) You must notify the
Transfer Agent, either directly or through the Distributor or your broker, at
the time the repurchase privilege is exercised to adjust your account for the
CDSC you previously paid. Thereafter, any redemptions will be subject to the
CDSC applicable



                                      B-37
<PAGE>


at the time of the redemption. See "Contingent Deferred Sales Charge" below.
Exercise of the repurchase privilege will generally not affect federal tax
treatment of any gain realized upon redemption. However, if the redemption was
made within a 30 day period of the repurchase and if the redemption resulted in
a loss, some or all of the loss, depending on the amount reinvested, may not be
allowed for federal income tax purposes.



      CONTINGENT DEFERRED SALES CHARGE



      Redemptions of Class B shares will be subject to a contingent deferred
sales charge or CDSC declining from 5% to zero over a six-year period. Class C
shares redeemed within 18 months of purchase will be subject to a 1% of 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 six years, in
the case of Class B shares, and 18 months, 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 CDSC will be paid to and retained by the
Distributor.



      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.



      The following table sets forth the rates of the CDSC applicable to
redemption of Class B shares:



                                                      CONTINGENT DEFERRED SALES

      YEAR SINCE PURCHASE                              OF DOLLARS INVESTED OR
      PAYMENT MADE                                       REDEMPTION PROCEEDS
      ------------                                       -------------------
      First .........................................            5.0%
      Second.........................................            4.0%
      Third..........................................            3.0%
      Fourth.........................................            2.0%
      Fifth..........................................            1.0%
      Sixth..........................................            1.0%
      Seventh........................................            None



      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 Class B shares made during the preceding six years
and 18 months for Class C shares; 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 decide to
redeem $500 of your investment. Assuming at the time of the redemption the NAV
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 4% (the applicable rate in the second year after
purchase) for a total CDSC of $9.60.



      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 CONTINGENT DEFERRED SALES CHARGE--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,



                                      B-38
<PAGE>


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 also will 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. For more information, call Prudential at (800) 353-2847.



      Finally, the CDSC will be waived to the extent that the proceeds from
shares redeemed are invested in Prudential Mutual Funds, The Guaranteed
Investment Account, the Guaranteed Insulated Separate Account or units of The
Stable Value Fund.



      SYSTEMATIC WITHDRAWAL PLAN. The CDSC will be waived (or reduced) on
certain redemptions from a Systematic Withdrawal Plan. On an annual basis, up to
12% of the total dollar amount subject to the CDSC may be redeemed without
charge. The Transfer Agent will calculate the total amount available for this
waiver annually on the anniversary date of your purchase. The CDSC will be
waived (or reduced) on redemptions until this threshold 12% is reached.



      In addition, the CDSC will be waived on redemptions of shares held by
Trustees of the Company.



      You must notify the Company's Transfer Agent either directly or through
your broker 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. In connection with these waivers, the Transfer Agent will require
you to submit the supporting documentation set forth below.

                                      B-39
<PAGE>


CONVERSION FEATURE--CLASS B SHARES



      Class B shares will automatically convert to Class A shares on a quarterly
basis approximately seven years after purchase. Conversions will be effected at
relative net asset value without the imposition of any additional sales charge.



      Since Prudential Stock Index 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: (1) the ratio of (a) the amounts paid for Class B shares
purchased at least seven years prior to the conversion date to (b) the total
amount paid for all Class B shares purchased and then held in your account (2)
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.



      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 seven 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 at total of $1,100), 95.24 shares would
convert approximately seven years from the initial purchase (that is, $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 NAV 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.



      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 would not
convert to Class A shares until approximately eight 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 may be subject to the continuing availability of
opinions of counsel or rulings of the Internal Revenue Service (1) that the
dividends and other distributions paid on Class A, Class B, Class C, Class I and
Class Z shares will not constitute "preferential dividends" under the Internal
Revenue Code and (2) 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 Prudential Stock Index Fund will continue to be subject,
possibly indefinitely, to their higher annual distribution and service fee.


                         SHAREHOLDER INVESTMENT ACCOUNT

      Upon the initial purchase of Fund shares, a Shareholder Investment Account
is established for each investor under which a record of the shares held is
maintained by the Transfer Agent. If a share 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. Each Fund makes available to its
shareholders the following privileges and plans.


                                      B-40
<PAGE>

AUTOMATIC REINVESTMENT OF DIVIDENDS AND DISTRIBUTIONS


      For the convenience of investors, all dividends and distributions are
automatically reinvested in full and fractional shares of the applicable Fund.
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 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 broker. Any
shareholder who receives a cash payment representing a dividend or distribution
may reinvest such dividend or distribution at NAV 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 NAV per share next determined after receipt of
the check or proceeds by the Transfer Agent.


EXCHANGE PRIVILEGE

      The Company makes available to its shareholders the privilege of
exchanging their shares of a Fund 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 such other
Prudential Mutual Funds may also be exchanged for shares of a Fund. All
exchanges are made on the basis of the relative NAV next determined after
receipt of an order in proper form. An exchange will be treated as a redemption
and purchase for tax purposes. 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.


      In order to exchange shares by telephone, you must authorize telephone
exchanges on your initial application form or by written notice to the Transfer
Agent and hold shares in non-certificate form. Thereafter, you may call the Fund
at (800) 225-1852 to execute a telephone exchange of shares, on 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.



      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.



      You may also exchange shares by mail by writing to Prudential Mutual Fund
Services LLC, 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 LLC, at the address noted above.



      CLASS Z. Class Z shares may be exchanged for Class Z shares of other
Prudential Mutual Funds, if the investor is eligible to purchase Class Z shares
of other Prudential Mutual Funds or, if not eligible, the investor may exchange
Class Z shares for Class A shares of other Prudential Mutual Funds.



      CLASS I. Class I shares of Prudential Stock Index Fund may be exchanged
for Class Z shares of other Prudential Mutual Funds.



      CLASS A. Shareholders of Prudential Stock Index Fund may exchange their
Class A shares for Class A shares of certain other Prudential Mutual Funds,
shares of Prudential Government Securities Trust (Short-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.

      CLASS B AND CLASS C. Shareholders of Prudential Stock Index Fund may
exchange their Class B shares and Class C shares of the Fund for Class B and
Class C shares of certain other Prudential Mutual Funds and shares of Prudential
Special Money Market Fund, Inc., a money market fund. No CDSC will be payable
upon such exchange, but a CDSC may be payable upon the redemption of the Class B
and Class C shares acquired as a result of an 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 Fund may also be exchanged for shares of
an eligible 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 into the Fund, such shares will be subject to the CDSC calculated
without regard to 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 CDSC,
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 Fund from a money market fund during the month
(and are held in the Fund 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 seven 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 Fund 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.



      SPECIAL EXCHANGE PRIVILEGES. A special exchange privilege is available for
shareholders who qualify to purchase Class A shares or Class Z shares. 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 for shareholders who qualify to
purchase Class A shares on a quarterly basis, unless the shareholder elects
otherwise.



      Shareholders who qualify to purchase Class Z shares will have their Class
B and Class C shares which are not subject to a CDSC and their Class A shares
exchanged for Class Z shares on a quarterly basis. 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 including 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 NAV above the total
amount of payments for the purchase of Class B or Class C



                                      B-42
<PAGE>


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, Prusec or
another broker that they are eligible for this special exchange privilege.



      Participants in any fee-based program for which Prudential Stock Index
Fund is an available option will have their Class A shares, if any, exchanged
for Class Z shares when they elect to have those assets become a part of the
fee-based program. Upon leaving the program (whether voluntarily or not), such
Class Z shares (and, to the extent provided for in the program, Class Z shares
acquired through participation in the program) will be exchanged for Class A
shares at NAV. Similarly, participants in Prudential Securities' 401(k) Plan for
which the Fund's Class Z shares is an available option and who wish to transfer
their Class Z shares out of the Prudential Securities 401(k) Plan following
separation from service (that is, voluntary or involuntary termination of
employment or retirement) will have their Class Z shares exchanged for Class A
shares at NAV.



      Additional details about the exchange privilege and prospectuses for each
of the Prudential Mutual Funds are available from the Company's Transfer Agent,
the Distributor or your broker. The exchange privilege may be modified,
terminated or suspended on 60 days' notice and any fund, including the Funds, 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 $6,000 at a public
university. Assuming these costs increase at a rate of 7% a year, as has been
projected, for the freshman class of 2011, the cost of four years at a private
college could reach $210,000 and over $90,000 at a public university.(1)

      The following chart shows how much you would need in monthly investments
to achieve specified lump sums to finance your investment goals.(2)

      their original cost.

      See "Automatic Investment Plan."


AUTOMATIC INVESTMENT PLAN (AIP)


      Under AIP, an investor may arrange to have a fixed amount automatically
invested in shares of a Fund monthly by authorizing his or her bank account or
brokerage account (including a Prudential Securities Command Account) to be
debited to invest specified dollar amounts in shares of a Fund. The investor's
bank must be a member of the Automatic Clearing House System. Stock certificates
are not issued to AIP participants.

      Further information about this program and an application form can be
obtained from the Transfer Agent, the Distributor or your broker.


SYSTEMATIC WITHDRAWAL PLAN


      A systematic withdrawal plan is available to shareholders through the
Distributor, your broker 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.



      In the case of shares held through the Transfer Agent (1) a $10,000
minimum account value applies, (2) withdrawals may not be for less than $100 and
(3) the shareholder must elect to have all dividends and/or distributions
automatically reinvested in additional full and fractional shares at NAV on
shares held under this plan. See "Shareholder Investment Account--Automatic
Reinvestment of Dividends and Distributions."



      The Distributor, Transfer Agent or your broker acts as an agent 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 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 be recognized for federal income tax purposes. In
addition, withdrawals made concurrently with purchases of additional shares are
inadvisable because of the CDSC applicable to the redemption of Class B and
Class C shares of Prudential Stock index Fund. 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 qualified retirement plans, including a 401(k) plan, self-directed
individual retirement accounts and "tax-deferred 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, and the administration, custodial fees and other details are
available from the Distributor 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.

(1)   The chart is for illustrative purposes only and does not represent the
      performance of a Fund or any specific investment. It shows taxable versus
      tax-deferred compounding for the periods and on the terms indicated.
      Earnings in a traditional IRA account will be subject to tax when
      withdrawn from the account. Distributions from a Roth IRA which meet the
      conditions required under the Internal Revenue Code will not be subject to
      tax upon withdrawal from the account.

MUTUAL FUND PROGRAMS


      From time to time, the Company (or a Fund of the Company) may be included
in a mutual fund program with other Prudential Mutual Funds. Under such a
program, a group of portfolios will be selected and thereafter marketed
collectively. Typically, these programs are created with an investment theme,
such as to seek greater diversification, protection from interest rate movements
or access to different management styles. In the event such a program is
instituted, there may be a minimum investment requirement for the program as a
whole. A Fund may waive or reduce the minimum initial investment requirements in
connection with such a program.


      The mutual funds in the program may be purchased individually or as a part
of a program. Since the allocation of portfolios included in the program may not
be appropriate for all investors, investors should consult their financial
advisor concerning the appropriate blend of portfolios for them. If investors
elect to purchase the individual mutual funds that constitute the program in an
investment ratio different from that offered by the program, the standard
minimum investment requirements for the individual mutual funds will apply.


                                 NET ASSET VALUE



      Each Fund'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 shares outstanding. NAV is calculated separately for each class of
Prudential Stock Index Fund. Each Fund will compute its NAV at 4:15 P.M., New
York Time, one each day the New York Stock Exchange is open for trading except
on days on which no orders to purchase, sell or redeem Fund shares have been
received or days on which changes in the value of the Fund's portfolio
securities do not affect NAV. In the event the New York Stock Exchange closes
early on any business day, the NAV of each Fund's shares shall be determined at
a time between such closing and 4:15 P.M., New York Time. The New York Stock
Exchange is closed on the following holidays: New Year's Day, Martin Luther
King, Jr. Day, President's Day, Good Friday, Memorial Day, Independence Day,
Labor Day, Thanksgiving Day and Christmas Day.



      Under the Investment Company Act, the Trustees are responsible for
determining in good faith the fair value of securities of each Fund. In
accordance with procedures adopted by the Trustees, the value of investments
listed on a securities exchange and NASDAQ National Market System securities
(other than options on stock and stock indices) are valued at the last sales
price on such exchange system on the day of valuation, or, if there was no sale
on such day, the mean between the last bid and asked prices on such day, or at
the bid price on such day in the absence of an asked price. Corporate bonds
(other than convertible debt securities) and U.S. Government securities that are
actively traded in the over-the-counter market, including listed securities for
which the primary market is believed by the Manager in consultation with the
Subadviser to be over-the-counter, are valued on the basis of valuations
provided by an independent pricing agent or principal market maker which uses
information with respect to transactions in bonds, quotations from bond dealers,
agency ratings, market transactions in comparable securities and various
relationships between securities in determining value. Convertible debt
securities that are actively traded in the over-the-counter market, including
listed securities for which the primary



                                      B-45
<PAGE>


market is believed by the Manager in consultation with the Subadviser to be
over-the-counter, are valued at the mean between the last reported bid and asked
prices provided by principal market makers. Options on stock and stock indexes
traded on an exchange are valued at the mean between the most recently quoted
bid and asked prices on the respective exchange and futures contracts and
options thereon are valued at their last sales prices as of the close of trading
on the applicable commodities exchange or board of trade or, if there was no
sale on the applicable commodities exchange or board of trade on such day, at
the mean between the most recently quoted bid and asked prices on such exchange
or board of trade. Quotations of foreign securities in a foreign currency are
converted to U.S. dollar equivalents at the current rate obtained from a
recognized bank or dealer and forward currency exchange contracts are valued at
the current cost of covering or offsetting such contracts. Should an
extraordinary event, which is likely to affect the value of the security, occur
after the close of an exchange on which a portfolio security is traded, such
security will be valued at fair value considering factors determined in good
faith by the investment adviser under procedures established by and under the
general supervision of the Fund's Trustees.



      Securities or other assets for which reliable market quotations are not
readily available, or for which the pricing agent or principal market maker does
not provide a valuation or methodology or provides a valuation of methodology
that, in the judgment of the Manager or Subadviser (or Valuation Committee or
Board of Trustees), does not represent fair value, are valued by the Valuation
Committee or Board of Trustees in consultation with the Manager or the
Subadviser, including its portfolio manager, traders, and its research and
credit analysis, on the basis of the following factors: cost of the security,
transactions in comparable securities, relationships among various securities
and such other factors as may be determined by the Manager, Subadviser, Board of
Trustees or Valuation Committee to materially affect the value of the security.
Short-term debt securities are valued at cost, with interest accrued or discount
amortized to the date of maturity, if their original maturity was 60 days or
less, unless this is determined by the Trustees not to represent fair value.
Short-term securities with remaining maturities of more than 60 days, for which
market quotations are readily available, are valued at their current market
quotations as supplied by an independent pricing agent or principal market
maker.



      Portfolio securities traded on more than one U.S. national securities
exchange or foreign securities exchange are valued at the last sale price on the
business day as of which such value is being determined at the close of the
exchange representing the principal market for such securities. The value of all
assets and liabilities expressed in foreign currencies will be converted into
U.S. dollar values at the current rate obtained from a recognized bank or
dealer. If such quotations are not available, the rate of exchange will be
determined in good faith by or under procedures established by the Trustees of
the Company.



      Trading in securities on European and Pacific securities exchanges and OTC
markets is normally completed well before the close of business on each business
day in New York (I.E., a day on which the NYSE is open for trading). In
addition, European or Pacific securities trading generally or in a particular
country or countries may not take place on all business days in New York.
Furthermore, trading takes place in various foreign markets on days which are
not business days in New York and on which the Funds' net asset values are not
calculated. Such calculation does not take place contemporaneously with the
determination of the prices of the majority of the portfolio securities used in
such calculation. Events affecting the values of portfolio securities that occur
between the time their prices are determined and the close of the regular
trading on the NYSE will not be reflected in a Fund's calculation of net asset
values unless, pursuant to procedures adopted by the Trustees, the Subadviser
deems that the particular event would materially affect net asset value, in
which case an adjustment will be made.



      The proceeds received by each Fund for each issue or sale of its shares,
and all net investment income, realized and unrealized gain and proceeds
thereof, subject only to the rights of creditors, will be specifically allocated
to such Fund and constitute the underlying assets of that Fund. The underlying
assets of each Fund will be segregated on the books of account, and will be
charged with the liabilities in respect to such Fund and with a share of the
general liabilities of the Company. Expenses with respect to any two or more
Funds are to be allocated in proportion to the net asset values of the
respective Funds except where allocations of direct expenses can otherwise be
fairly made.



      Although the legal rights of each class of shares of Prudential Stock
Index Fund are substantially identical, the different expenses borne by each
class will result in different NAVs. 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. The
NAV of Class I and Class Z shares will generally be higher than the NAV of



                                      B-46
<PAGE>


Class A, Class B or Class C shares as a result of the fact that Class I and
Class Z shares are not subject to any distribution or service fee. It is
expected, however, that the NAV per share of each class will tend to converge
immediately after the recording of dividends, if any, which will differ by
approximately the amount of the distribution and/or service fee expense accrual
differential among the classes.



                       TAXES, DIVIDENDS AND DISTRIBUTIONS



      Each Fund has elected to qualify and intends to remain qualified as a
regulated investment company under Subchapter M of the Internal Revenue Code.
This relieves the Fund (but not its shareholders) from paying federal income tax
on income and capital gains which are distributed to shareholders, and permits
net capital gains of the Fund (that is, 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 Fund. Net capital gains of a Fund which are available for
distribution to shareholders will be computed by taking into account any capital
loss carryforward of the Fund.



      Qualification of a Fund as a regulated investment company requires, among
other things, that (a) the Fund derive at least 90% of its annual gross income,
without reduction for losses from the sale or other disposition of securities or
foreign currencies, from payments with respect to securities loans, Interest,
dividends and gains from the sale or other disposition of securities or options
thereon or foreign currencies, or other income (including but not limited to
gains from options, futures or forward contracts) derived with respect to its
business of Investing in such securities or currencies; (b) the Fund diversify
Its holdings so that, at the end of each quarter of the taxable year, (1) at
least 50% of the value of the Fund's assets is represented by cash, U.S.
Government securities and other securities limited in respect of any one issuer
to an amount not greater than 5% of the value of the assets of the Fund and 10%
of the outstanding voting securities of such issuer, and (2) not more than 25%
of the value of its assets is invested in the securities of any one issuer
(other than U.S. Government securities); and (c) the Fund distribute to its
shareholders at least 90% of its net investment income and net short-term gains
(that is, the excess of net short-term capital gains over net long-term capital
losses) in each year.



      Gains or losses on sales of securities by a Fund 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 Fund acquires a put or
writes a call thereon or otherwise holds an offsetting position with respect to
the securities. Other gains or losses on the sale of securities will be
short-term capital gains or losses. Gains and losses on the sale, lapse or other
termination of options on securities will be treated as gains and losses from
the sale of securities. If an option written by the Fund on securities lapses or
is terminated through a closing transaction, such as a repurchase by the Fund of
the option from its holder, the Fund will generally realize short-term capital
gain or loss. If securities are sold by the Fund pursuant to the exercise of a
call option written by it, the Fund will include the premium received in the
sale proceeds of the securities delivered in determining the amount of gain or
loss on the sale. If securities are purchased by the Fund pursuant to the
exercise of a put option written by it, the Fund will subtract the premium
received from its cost basis in the securities purchased. Certain transactions
of the Fund may be subject to wash sale, short sale, constructive sale, straddle
and anti-conversion provisions of the Internal Revenue Code which may, among
other things, require the Fund to defer recognition of losses. In addition, debt
securities acquired by the Fund may be subject to original issue discount and
market discount rules which, respectively, may cause the Fund to accrue income
in advance of the receipt of cash with respect to interest or cause gains to be
treated as ordinary income.



      Special rules will apply to most options on stock indexes, futures
contracts and options thereon, and foreign currency forward contracts in which a
Fund may invest. 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 Fund's taxable year; that is, treated as having been
sold at market value. Except with respect to certain forward foreign currency
exchange contracts, 60 percent of any gain or loss recognized on these "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.



      Forward currency contracts, options and futures contracts entered into by
a Fund may create "straddles" for federal income tax purposes. Positions which
are part of a straddle will be subject to certain wash sale, short sale and
constructive sale provisions of the Internal Revenue Code. In the case of a
straddle, the Fund may be required



                                      B-47
<PAGE>


to defer the recognition of losses on positions it holds to the extent of any
unrecognized gain on offsetting positions held by the Fund



      Gains or losses attributable to fluctuations in exchange rates which occur
between the time a Fund accrues interest or other receivables or accrues
expenses or other liabilities denominated in a foreign currency and the time the
Fund actually collects such receivables or pays such liabilities are treated as
ordinary income or ordinary loss. Similarly, gains or losses on foreign currency
forward contracts or dispositions of debt securities denominated in a foreign
currency attributable to fluctuations in the value of the foreign currency
between the date of acquisition of the security and the date of disposition also
are treated as ordinary gain or loss. These gains or losses, referred to under
the internal Revenue Code as "Section 988" gains or losses, increase or decrease
the amount of the Fund's investment company taxable income available to be
distributed to its shareholders as ordinary income, rather than increasing or
decreasing the amount of the Fund's net capital gain. If Section 988 losses
exceed other investment company taxable income during a taxable year, the Fund
would not be able to make any ordinary dividend distributions, or distributions
made before the losses were realized would be recharacterized as a return of
capital to shareholders, rather than as an ordinary dividend, reducing each
shareholder's basis in his or her Fund shares.



      Shareholders electing to receive dividends and 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 NAV of a share of the relevant Fund on the
reinvestment date.



      Each Fund is required under the Internal Revenue Code to distribute 98% of
its ordinary income in the same calendar year in which it is earned. Each Fund
also is required to distribute during the calendar year 98% of the capital gain
net income it earned during the twelve months ending on October 31 of such
calendar year. In addition, each Fund must distribute during the calendar year
any undistributed ordinary income and undistributed capital gain net income from
the prior year or the twelve month period ending on October 31 of such prior
year, respectively. To the extent it does not meet these distribution
requirements, a Fund will be subject to a non-deductible 4% excise tax on the
undistributed amount. For purposes of this excise tax, income on which a Fund
pays income tax is treated as distributed.



      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 a Fund, the investor should carefully consider the impact of dividends
or capital gains distributions which are expected to be or have been announced.



      Any loss realized on a sale, redemption or exchange of shares of a Fund 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 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 Fund.



      Income received by a Fund from sources within foreign countries may be
subject to withholding and other taxes imposed by such countries. Income tax
treaties between certain countries and the United States may reduce or eliminate
such taxes. It is impossible to determine in advance the effective rate of
foreign tax to which a Fund will be subject, since the amount of the Fund's
assets to be invested in various countries is not known. Foreign shareholders
are advised to consult their own tax advisers with respect to the particular tax
consequences of an investment in a Fund.



      A Fund may, from time to time, invest in Passive Foreign Investment
Companies (PFICs). A PFIC is a foreign corporation that, in general, meets
either of the following tests: (1) at least 75% of its gross income is passive
or (2) an average of at least 50% of its assets produce, or are held for the
production of, passive income. If the Fund acquires and holds stock in a PFIC
beyond the end of the year of its acquisition, the Fund will be subject to
federal income tax on a portion of any "excess distribution" received on the
stock or on any gain from disposition of the stock (collectively, PFIC income),
plus interest thereon, even if the Fund distributes the PFIC income as a taxable
dividend to its shareholders. The balance of the PFIC income will be included in
the Fund's investment company taxable income and, accordingly, will not be
taxable to it to the extent that income is distributed to its shareholders.



                                      B-48
<PAGE>


The Fund may make a "mark-to-market" election with respect to any marketable
stock it holds of a PFIC. If the election is in effect, at the end of the Fund's
taxable year, the Fund will recognize the amount of gains, if any, as ordinary
income with respect to PFIC stock. No loss will be recognized on PFIC stock,
except to the extent of gains recognized in prior years. Alternatively, the
Fund, if it meets certain requirements, may elect to treat any PFIC in which it
invests as a "qualified electing fund," in which case, in lieu of the foregoing
tax and interest obligation, the Fund will be required to include in income each
year its PRO RATA share of the qualified electing fund's annual ordinary
earnings and net capital gain, even if they are not distributed to the Fund;
those amounts would be subject to the distribution requirements applicable to
the Fund described above. Dividends and distributions also may be subject to
state and local taxes.


                             PERFORMANCE INFORMATION

AVERAGE ANNUAL TOTAL RETURN


      A Fund may from time to time advertise its average annual total return.
Average annual total return is determined separately for each class.


      A Fund's "average annual total return" is computed according to a formula
prescribed by the SEC, expressed as follows:

                                 P(1+T)^n = ERV

Where: P = a hypothetical initial payment of $1,000.
       T = average annual total return.
       n = number of years.
       ERV = Ending Redeemable Value (ERV) at the end of a 1-, 5- or 10-year
             period (or fractional portion thereof) of a hypothetical $1,000
             investment made at the beginning of a 1-, 5- or 10-year period.

      Average annual total 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 the Class Z shares of Prudential Stock
Index Fund for the one year and five years ended March 31, 1999 and from
commencement of operations (November 5, 1992) through March 31, 1999 was 18.23%,
25.65% and 21.26%, respectively. The average annual total return for Class I
shares of Prudential Stock Index Fund from the commencement of operations
(August 1, 1997) through March 31, 1999 and the year ended March 31, 1999 was
21.54% and 18.24%, respectively. The average annual total return for the Class Z
shares of Prudential Pacific Index Fund from commencement of operations
(September 24, 1997) through March 31, 1999 and for the one year ended March 31,
1999 was 7.48% and 9.87%, respectively. The average annual total return from
the commencement of operations (October 1, 1997) through March 31, 1999 for
Prudential Bond Market Index Fund, Prudential Europe Index Fund and Prudential
Small-Cap Index Fund was 7.03%, 15.54% and (9.70%), respectively, and for the
year ended March 31, 1999 was 6.35%, 4.95% and (18.55%), respectively.


AGGREGATE TOTAL RETURN


      A Fund may also advertise its aggregate total return. Aggregate total
return is determined separately for each class.


      A Fund's aggregate total return represents the cumulative change in the
value of an investment in the Fund for the specified period and is computed by
the following formula:


                                      B-49
<PAGE>

                                     ERV - P
                                     -------
                                        P

Where: P = a hypothetical initial payment of $1,000.
       ERV =  Ending Redeemable Value (ERV) at the end of a 1-, 5- or 10-year
              period (or fractional portion thereof) of a hypothetical $1,000
              investment made at the beginning of a 1-, 5- or 10-year period
              assuming reinvestment of all dividends and distributions and the
              effect of the maximum annual fee for participation in the Company.

      The ERV assumes complete redemption of the hypothetical investment at the
end of the measuring period.

      Aggregate total return does not take into account any federal or state
income taxes that may be payable upon redemption.


      A Fund's performance will vary from time to time depending upon market
conditions, the composition of its portfolio and its operating expenses.
Consequently, any given performance quotation should not be considered
representative of a Fund's performance for any specified period in the future.
In addition, because performance will fluctuate, it may not provide a basis for
comparing an investment in the Fund with certain bank deposits or other
investments that pay a fixed yield for a stated period of time. Investors
comparing a Fund's performance with that of other mutual funds should give
consideration to the quality and maturity of the respective investment
companies' portfolio securities. The aggregate total return for the one year
ended March 31, 1999 and the period from commencement of operations (September
24, 1997) through March 31, 1999 for Class Z shares of Prudential Pacific Index
Fund was 9.87% and (11.11%), respectively. The aggregate total returns for the
one year, five years and since inception periods ended March 31, 1999 for
Prudential Stock Index Fund's Class Z shares were 18.25%, 213.14% and 243.24%,
respectively. The aggregate total return for Class I shares of Prudential Stock
Index Fund for the one year ended March 31, 1999 and the period from
commencement of operations (August 1, 1997) through March 31, 1999 was 18.24%,
and 38.29%, respectively. The aggregate total return since inception (October 1,
1997) through March 31, 1999 for Prudential Bond Market Index Fund, Prudential
Europe Index Fund and Prudential Small-Cap Index Fund was 10.69%, 24.11% and
(12.91%), respectively, and for the one year period ended March 31, 1999 was
(6.35%), 4.95% and (18.58%), respectively.

                                             PRUDENTIAL INDEX SERIES FUND
Notes to Financial Statements                PRUDENTIAL BOND MARKET INDEX FUND
- --------------------------------------------------------------------------------
Prudential Index Series Fund, (the 'Company') is registered under the Investment
Company Act of 1940 as an open-end, diversified management investment company.
The Company was established as a Delaware business trust on May 11, 1992 and
currently consists of five separate funds. Prudential Bond Market Index Fund
(the 'Fund') commenced investment operations on October 1, 1997 when 3,000,020
shares of beneficial interest of the Fund were sold for $30,000,200 to the
Prudential Insurance Company of America ('The Prudential').

The Fund's investment objective is to seek to provide investment results that
correspond to the total return performance of a broad-based index of
fixed-income securities, currently the Lehman Brothers Aggregate Bond Index.
- ------------------------------------------------------------
Note 1. Accounting Policies

The following is a summary of significant accounting policies followed by the
Company and the Fund in the preparation of its financial statements.

Security Valuation: Securities for which the primary market is on an exchange
are valued at the last sale price on such exchange on the day of valuation or,
if there were no sales on such day, at the mean between the last bid price in
the absence of an asked price. Securities that are actively traded in the
over-the-counter market, including listed securities for which the primary
market is believed to be over-the-counter, are valued by an independent pricing
agent or a principal market maker. U.S. Government securities for which market
quotations are available are valued at a price provided by an independent
broker/dealer or pricing service.

Options on securities that are listed on an exchange are valued at the last
sales price at the close of trading on such exchange or, if there were no sales
on the applicable option exchange, on such day at the average of the quoted bid
and asked prices as of the close of such exchange. Futures contracts and options
thereon traded on a commodities exchange or board of trade are valued at the
last sale price at the close of trading on such exchange or board of trade or,
if there was no sale on the applicable commodities exchange or board of trade on
such day, at the average of the quoted bid and asked prices as of the close of
such exchange or board of trade. Securities for which reliable market quotations
are not available or for which the pricing agent or principal market maker does
not provide a valuation or methodology that, in the judgement of the subadviser,
does not represent fair value, are valued at fair value as determined by
procedures established by the Company's Trustees.

Short-term securities which mature in more than 60 days are valued at current
market quotations. Short-term securities which mature in 60 days or less are
valued at amortized cost.

In connection with transactions in repurchase agreements with U.S. financial
institutions, it is the Company's policy that its custodian or designated
subcustodians, under triparty repurchase agreements as the case may be, take
possession of the underlying collateral securities, the value of which exceeds
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.

Dollar Rolls: The Fund enters into mortgage dollar rolls in which the Fund sells
mortgage securities for delivery in the current month, realizing a gain or loss
and simultaneously contracts to repurchase somewhat similar (same type, coupon
and maturity) securities on a specified future date. During the roll period, the
Fund forgoes principal and interest paid on the securities. The Fund is
compensated by the interest earned on the cash proceeds of the initial sale and
by the lower repurchase price at the future date. The difference between the
sales proceeds and the lower repurchase price is recorded as interest income.
The Fund maintains a segregated account, the dollar value of which is at least
equal to its obligations, in respect of dollar rolls.

Securities Transactions and Net Investment Income: Securities transactions are
recorded on the trade date. Realized gains or losses from investment
transactions are calculated on the identified cost basis. Interest income is
recorded on the accrual basis. The Fund accretes discounts and amortizes
premiums on portfolio securities as adjustments to interest income. Expenses are
recorded on the accrual basis which may require the use of certain estimates by
management.

Dividends and Distributions: The Fund expects to pay dividends of net investment
income and distributions of net realized capital gains, if any, at least
annually. Dividends and distributions are recorded on the ex-dividend date.

Income distributions and capital gain distributions are determined in accordance
with income tax regulations which may differ from generally accepted accounting
principles.

Notes to Financial Statements                 PRUDENTIAL BOND MARKET INDEX FUND
- --------------------------------------------------------------------------------
Taxes: For federal income tax purposes, each fund in the Company is treated as a
separate taxpaying entity. It is the Fund's policy to meet the requirements of
the Internal Revenue Code applicable to regulated investment companies and to
distribute all of its taxable net investment income to its shareholders.
Therefore, no federal income tax provision is required.

Deferred Offering Expenses: Approximately $20,000 of expenses were incurred in
connection with the organization of the Fund. These costs were deferred and
amortized over a period of one year from the date the Fund commenced investment
operations.

Reclassification of Capital Accounts: The Fund accounts and reports for
distributions to shareholders in accordance with American Institute of Certified
Public Accountants' Statement of Position 93-2: Determination, Disclosure, and
Financial Statement Presentation of Income, Capital Gain, and Return of Capital
Distributions by Investment Companies. The effect of applying this statement was
to increase undistributed net investment income and decrease paid-in capital by
$19,623 due to certain expenses not deductible for tax purposes. Net investment
income, net realized gains and net assets were not affected by this change.
- ------------------------------------------------------------
Note 2. Agreements

The Company has a management agreement with Prudential Investments Fund
Management LLC ('PIFM'). Pursuant to this agreement, PIFM has responsibility for
all investment advisory services and supervises the subadviser's performance of
such services. PIFM has entered into a subadvisory agreement with The Prudential
Investment Corporation ('PIC'); PIC furnishes investment advisory services in
connection with the management of the Company. PIFM pays for the cost of the
subadviser's services, the compensation of officers of the Company, occupancy
and certain clerical and bookkeeping costs of the Company. The Company bears all
other costs and expenses.

The management fee paid PIFM is computed daily and payable monthly, at an annual
rate of .25 of 1% of the Fund's average daily net assets.

The Company had a distribution agreement with Prudential Securities Incorporated
('PSI') which acted as the distributor of the Company through May 31, 1998.
Prudential Investment Management Services LLC ('PIMS') became the Company's
distributor effective June 1, 1998 and is serving the Company under the same
terms and conditions as under the arrangement with PSI. No distribution or
service fees are paid to PIMS as distributor of the Fund.

PSI, PIFM, PIC and PIMS are indirect wholly owned subsidiaries of The Prudential
Insurance Company of America.

PIFM has agreed to subsidize the operating expenses of the Fund, so that total
Fund operating expenses do not exceed .40% on an annualized basis of the Fund's
average daily net assets. This voluntary waiver may be terminated at any time
without notice. For the period ended September 30, 1998, PIFM subsidized
$170,875 of the expenses of the Fund (0.51% of the average daily net assets
annualized or $0.047 per share).

The Company, along with other affiliated registered investment companies (the
'Funds'), has a credit agreement (the 'Agreement') with an unaffiliated lender.
The maximum commitment under the Agreement is $200,000,000. Interest on any such
borrowings outstanding will be at market rates. The purpose of the Agreement is
to serve as an alternative source of funding for capital share redemptions. The
Fund did not borrow any amounts pursuant to the Agreement during the period
ended September 30, 1998. The Fund pays a commitment fee at an annual rate of
 .055 of 1% on the unused portion of the credit facility. The commitment fee is
accrued and paid quarterly on a pro rata basis by the Funds. The Agreement
expires on December 29, 1998.
- ------------------------------------------------------------
Note 3. Other Transactions With Affiliates

Prudential Mutual Fund Services LLC ('PMFS'), a wholly owned subsidiary of PIFM,
serves as the Company's transfer agent. During the period ended September 30,
1998, the Fund incurred fees of approximately $1,800 for the services of PMFS.
As of September 30, 1998, approximately $300 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 nonaffiliates.
- ------------------------------------------------------------
Note 4. Portfolio Securities

Purchases and sales of investment securities, other than short-term investments,
for the period ended September 30, 1998, were $28,705,632 and $10,569,626,
respectively, which includes purchases and sales of U.S. government obligations
of $16,880,613 and $4,995,544, respectively.

The federal income tax basis of the Fund's investments at September 30, 1998 was
substantially the same as for financial reporting purposes and, accordingly, net
unrealized appreciation for federal income tax purposes was $1,430,819 (gross
unrealized appreciation-$1,435,414; gross unrealized depreciation-$4,595).

- --------------------------------------------------------------------------------
The average balance of dollar rolls outstanding during the period ended
September 30, 1998 was approximately $7,441,249. The value of dollar rolls
outstanding at September 30, 1998 was $9,256,835, which was 16% of total assets.
- ------------------------------------------------------------
Note 5. Joint Repurchase Agreement Account

The Company, along with other affiliated registered investment companies,
transfers uninvested cash balances into a single joint account, the daily
aggregate balance of which is invested in one or more repurchase agreements
collateralized by U.S. Treasury or federal agency obligations. As of September

Report of Independent Accountants            PRUDENTIAL BOND MARKET INDEX FUND
- --------------------------------------------------------------------------------
To the Shareholders and Board of Trustees of
Prudential Index Series Fund--Prudential Bond Market Index Fund

In our opinion, the accompanying statement of assets and liabilities, including
the portfolio of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of Prudential Index Series
Fund--Prudential Bond Market Index Fund (the 'Fund,' one of the portfolios
constituting Prudential Index Series Fund) at September 30, 1998, and the
results of its operations, the changes in its net assets and the financial
highlights for the period October 1, 1997 (commencement of operations) through
September 30, 1998, in conformity with generally accepted accounting principles.
These financial statements and financial highlights (hereafter referred to as
'financial statements') are the responsibility of the Fund's management; our
responsibility is to express an opinion on these financial statements based on
our audit. We conducted our audit of these financial statements in accordance
with generally accepted auditing standards which require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audit, which included confirmation of securities at
September 30, 1998 by correspondence with the custodian and brokers, provides a
reasonable basis for the opinion expressed above.

Notes to Financial Statements                    PRUDENTIAL EUROPE INDEX FUND
- --------------------------------------------------------------------------------
Prudential Index Series Fund, (the 'Company'), is registered under the
Investment Company Act of 1940 as an open-end diversified management investment
company. The Company was established as a Delaware business trust on May 11,
1992 and currently consists of five separate Funds. Prudential Europe Index Fund
(the 'Fund') commenced investment operations on October 1, 1997 when 1,500,000
shares of beneficial interest of the Fund were sold for $15,000,000 to The
Prudential Insurance Company of America ('The Prudential').

The Fund's investment objective is to seek to provide investment results that
correspond to the price and yield performance of a broad-based index of
securities of European issuers, currently the Morgan Stanley Capital
International Europe Index.
- ------------------------------------------------------------
Note 1. Accounting Policies

The following is a summary of significant accounting policies followed by the
Company and the Fund in the preparation of its financial statements.

Securities Valuation: Securities for which the primary market is on an exchange,
are valued at the last sale price on such exchange on the day of valuation or,
if there were no sales on such day, at the mean between the last bid and asked
prices on such day or at the bid price in the absence of an asked price.
Securities that are actively traded in the over-the-counter market, including
listed securities for which the primary market is believed to be
over-the-counter, are valued by an independent pricing agent or a principal
market maker. Securities for which reliable market quotations are not available
or for which the pricing agent or principal market maker does not provide a
valuation or methodology or provides a valuation or methodology that, in the
judgment of the subadviser, does not represent fair value, are valued at fair
value as determined by procedures established by the Company's Trustees.

Short-term securities which mature in more than 60 days are valued at current
market quotations. Short-term securities which mature in 60 days or less are
valued at amortized cost.

In connection with transactions in repurchase agreements with U.S. financial
institutions, it is the Company's policy that its custodian or designated
subcustodians, under triparty repurchase agreements, as the case may be, takes
possession of the underlying collateral securities, the value of which exceeds
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.

Foreign Currency Translation: The books and records of the Fund are maintained
in U.S. dollars. Foreign currency amounts are translated into U.S. dollars on
the following basis:

(i) market value of investment securities, other assets and liabilities--at the
closing rates of exchange;

(ii) purchases and sales of investment securities, income and expenses--at the
rate of exchange prevailing on the respective dates of such transactions.

Although the net assets of the Fund are presented at the foreign exchange rates
and market values at the close of the fiscal period, the Fund does not isolate
that portion of the results of operations arising as a result of changes in the
foreign exchange rates from the fluctuations arising from changes in the market
prices of securities held at the end of the fiscal period. Similarly, the Fund
does not isolate the effect of changes in foreign exchange rates from the
fluctuations arising from changes in the market prices of long-term securities
sold during the fiscal period. Accordingly, realized foreign currency gains
(losses) are included in the reported net realized gains on investment
transactions.

Net realized losses on foreign currency transactions represent net foreign
exchange gains or losses from forward currency contracts, disposition of foreign
currencies, currency gains or losses realized between the trade and settlement
dates on security transactions, and the difference between the amounts of
interest, dividends and foreign taxes recorded on the Fund's books and the U.S.
dollar equivalent amounts actually received or paid. Net currency gains and
losses from valuing foreign currency denominated assets and liabilities at
fiscal period end exchange rates are reflected as a component of unrealized
appreciation on investments and foreign currencies.

Foreign security and currency transactions may involve certain considerations
and risks not typically associated with those of domestic origin as a result of,
among other factors, the possibility of political and economic instability and
the level of governmental supervision and regulation of foreign securities
markets.

Forward Currency Contracts: A forward currency contract is a commitment to
purchase or sell a foreign currency at a future date at a negotiated forward
rate. The Fund enters into forward currency contracts in order to hedge its
exposure to changes in foreign currency exchange rates on its foreign
- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------
portfolio holdings or on specific receivables and payables denominated in a
foreign currency. The contracts are valued daily at current exchange rates and
any unrealized gain or loss is included in net unrealized appreciation or
depreciation on investments. Gain or loss is realized on settlement date of the
contract equal to the difference between settlement value of the original and
renegotiated forward contracts. This gain or loss, if any, is included in net
realized gain (loss) on foreign currency transactions. Risks may arise upon
entering into these contracts from the potential inability of the counter
parties to meet the terms of their contracts.

Financial Futures Contracts: A financial futures contract is an agreement to
purchase (long) or sell (short) an agreed amount of securities or commodities at
a set price for delivery on a future date. Upon entering into a financial
futures contract, the Fund is required to pledge to the broker an amount of cash
and/or other assets equal to a certain percentage of the contract amount. This
amount is known as the 'initial margin.' Subsequent payments, known as
'variation margin,' are made or received by the Fund each day, depending on the
daily fluctuations in the value of the underlying security. Such variation
margin is recorded for financial statement purposes on a daily basis as
unrealized gain or loss. When the contract expires or is closed, the gain or
loss is realized and is presented in the statement of operations as net realized
gain (loss) on financial futures contracts.

The Fund invests in financial futures contracts in order to hedge existing
portfolio securities, or securities the Fund intends to purchase, against
fluctuations in value. Under a variety of circumstances, the Fund may not
achieve the anticipated benefits of the financial futures contracts and may
realize a loss. The use of futures transactions involves the risk of imperfect
correlation in movements in the price of futures contracts and the underlying
assets.

Securities Transactions and Net Investment Income: Securities transactions are
recorded on the trade date. Realized gains and losses from investment and
foreign currency transactions are calculated on the identified cost basis.
Dividend income is recorded on the ex-dividend date and interest income is
recorded on an accrual basis. Expenses are recorded on the accrual basis which
may require the use of certain estimates by management.

Dividends and Distributions: The Fund expects to pay dividends of net investment
income and distributions of net realized capital and currency gains, if any,
annually. Dividends and distributions are recorded on the ex-dividend date.

Income distributions and capital gain distributions are determined in accordance
with income tax regulations which may differ from generally accepted accounting
principles.

Taxes: It is the Fund's policy to meet the requirements of the Internal Revenue
Code applicable to regulated investment companies and to distribute all of its
taxable income to shareholders. Therefore, no federal income tax provision is
required.

Withholding taxes on foreign dividends, interest and capital gains have been
provided for in accordance with the Fund's understanding of the applicable
country's tax rules and rates.

Reclassification of Capital Accounts: The Fund accounts for and reports
distributions to shareholders in accordance with American Institute of Certified
Public Accountants (AICPA), Statement of Position 93-2: Determination,
Disclosure, and Financial Statement Presentation of Income, Capital Gain, and
Return of Capital Distributions by Investment Companies. The effect of applying
this statement was to increase undistributed net investment income by $32,747,
decrease accumulated realized gains by $13,049 and decrease paid-in capital in
excess of par by $19,698 relating to net realized foreign currency losses and
nondeductible offering cost. Net investment income, net realized gains and net
assets were not affected by this change.
- ------------------------------------------------------------
Note 2. Agreements

The Company has a management agreement with Prudential Investments Fund
Management LLC ('PIFM'). Pursuant to this agreement, PIFM has responsibility for
all investment advisory services and supervises the subadviser's performance of
such services. PIFM has entered into a subadvisory agreement with The Prudential
Investment Corporation ('PIC'); PIC furnishes investment advisory services in
connection with the management of the Fund. PIFM pays for the cost of the
subadviser's services, the compensation of officers of the Company, occupancy
and certain clerical and bookkeeping costs of the Company. The Company bears all
other costs and expenses.

The management fee paid to PIFM is computed daily and payable monthly at an
annual rate of .40 of 1% of the average daily net assets of the Fund.

PIFM has agreed to subsidize the operating expenses of the Fund so that total
Fund operating expenses do not exceed .60% on an annualized basis of the Fund's
average daily net assets. This voluntary waiver may be

terminated at any time without notice. For the period ended September 30, 1998,
PIFM subsidized $358,832 of the expenses of the Fund (2.02% of average net
assets, or $0.21 per share).

The Fund had a distribution agreement with Prudential Securities Incorporated
('PSI'), which acted as the distributor of the Fund through May 31, 1998.
Prudential Investment Management Services LLC ('PIMS') became the distributor of
the Fund effective June 1, 1998 and is serving the Fund under the same terms and
conditions as under the arrangement with PSI. No distribution or service fees
are paid to PSI or PIMS as distributor of the Fund.

PSI, PIFM, PIMS and PIC are wholly owned subsidiaries of The Prudential.

The Fund, along with other affiliated registered investment companies (the
'Funds'), has a credit agreement (the 'Agreement') with an unaffiliated lender.
The maximum commitment under the Agreement is $200,000,000. Interest on any such
borrowings outstanding will be at market rates. The purpose of the Agreement is
to serve as an alternative source of funding for capital share redemptions. The
Fund did not borrow any amounts pursuant to the Agreement during the period
ended September 30, 1998. The Funds pay a commitment fee at an annual rate of
 .055 of 1% on the unused portion of the credit facility. The commitment fee is
accrued and paid quarterly on a pro rata basis by the Funds. The Agreement
expired on December 30, 1997 and has been extended through December 29, 1998
under the same terms.
- ------------------------------------------------------------
Note 3. Other Transactions With Affiliates

Prudential Mutual Fund Services LLC ('PMFS'), a wholly owned subsidiary of PIFM,
serves as the Company's transfer agent. During the period October 1, 1997
through September 30, 1998, the Fund incurred fees of approximately $1,000 for
the services of PMFS. As of September 30, 1998, approximately $200 of such fees
were due to PMFS. Transfer agent fees and expenses in the Statement of
Operations include certain out-of-pocket expenses paid to nonaffiliates.
- ------------------------------------------------------------
Note 4. Portfolio Securities

Purchases and sales of investment securities, other than short-term investments,
for the period ended September 30, 1998 were $17,644,283 and $656,636,
respectively.

The United States federal income tax cost basis of the Fund's investments at
September 30, 1998 was $17,249,634 and, accordingly, net unrealized appreciation
for federal income tax purposes was $579,844 (gross unrealized
appreciation--$2,333,194; gross unrealized depreciation--$1,753,350).

At September 30, 1998, the Fund had outstanding forward currency contracts to

Report of Independant Accountants                PRUDENTIAL EUROPE INDEX FUND
- --------------------------------------------------------------------------------
To the Shareholders and Board of Trustees of
Prudential Index Series Fund--Prudential Europe Index Fund

In our opinion, the accompanying statement of assets and liabilities, including
the portfolio of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of Prudential Index Series
Fund--Prudential Europe Index Fund (the 'Fund', one of the portfolios
constituting Prudential Index Series Fund) at September 30, 1998, and the
results of its operations, the changes in its net assets and the financial
highlights for the period October 1, 1997 (commencement of operations) through
September 30, 1998, in conformity with generally accepted accounting principles.
These financial statements and financial highlights (hereafter referred to as
'financial statements') are the responsibility of the Fund's management; our
responsibility is to express an opinion on these financial statements based on
our audit. We conducted our audit of these financial statements in accordance
with generally accepted auditing standards which require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audit, which included confirmation of securities at
September 30, 1998 by correspondence with the custodian and brokers, provides a
reasonable basis for the opinion expressed above.

Notes to Financial Statements         PRUDENTIAL PACIFIC INDEX FUND
- --------------------------------------------------------------------------------
Prudential Index Series Fund, (the 'Company') is registered under the Investment
Company Act of 1940 as an open-end, diversified management investment company.
The Company was established as a Delaware business trust on May 11, 1992 and
currently consists of five separate funds. Prudential Pacific Index Fund (the
'Fund') commenced investment operations on September 24, 1997 when 2,500,020
shares of beneficial interest of the Fund were sold for $25,000,200 to The
Prudential Insurance Company of America ('The Prudential'). The investment
objective of the Fund is to seek to provide investment results that correspond
to the price and yield performance of a broad-based index of securities of
issuers in the Pacific region, currently the Morgan Stanley Capital
International Pacific Free Index ('MSCI-PFI').
- ------------------------------------------------------------
Note 1. Accounting Policies
The following is a summary of significant accounting policies followed by the
Company and the Fund in the preparation of its financial statements.
Securities Valuation: Securities for which the primary market is on an exchange
are valued at the last sale price on such exchange on the day of valuation or,
if there was no sale on such day, at the mean between the last bid and asked
prices on such day or at the bid price in the absence of an asked price.
Securities that are actively traded in the over-the-counter market, including
listed securities for which the primary market is believed to be
over-the-counter, are valued by an independent pricing agent or a principal
market maker. U.S. Government securities for which market quotations are readily
available are valued at a price provided by an independent broker/dealer or
pricing service. Securities for which reliable market quotations are not
available or for which the pricing agent or principal market maker does not
provide a valuation or methodology or provides a valuation or methodology that,
in the judgment of the subadviser, does not represent fair value, are valued at
fair value as determined by procedures established by the Company's Trustees.
Due to current market conditions, the Company's Board of Directors reduced the
valuation of securities held in Malaysian currency by 30 percent effective
September 30, 1998.
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 with U.S. financial
institutions, it is the Company's policy that its custodian or designated
subcustodians under triparty repurchase agreements, as the case may be, takes
possession of the underlying collateral securities, the value of which exceeds
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.
All securities are valued as of 4:15 p.m., New York time.
Foreign Currency Translation: The books and records of the Fund are maintained
in U.S. dollars. Foreign currency amounts are translated into U.S. dollars on
the following basis:
(i) market value of investment securities, other assets and liabilities--at the
closing rates of exchange;
(ii) purchases and sales of investment securities, income and expenses--at the
rate of exchange prevailing on the respective dates of such transactions.
Although the net assets of the Fund are presented at the foreign exchange rates
and market values at the close of the fiscal year, the Fund does not isolate
that portion of the results of operations arising as a result of changes in the
foreign exchange rates from the fluctuations arising from changes in the market
prices of securities held at the end of the fiscal year. Similarly, the Fund
does not isolate the effect of changes in foreign exchange rates from the
fluctuations arising from changes in the market prices of long-term debt
securities sold during the fiscal year. Accordingly, realized foreign currency
gains (losses) are included in the reported net realized gains on investment
transactions.
Net realized losses on foreign currency transactions represent net foreign
exchange gains or losses from forward currency contracts, disposition of foreign
currencies, currency gains or losses realized between the trade and settlement
dates on security transactions, and the difference between the amounts of
interest, dividends and foreign taxes recorded on the Fund's books and the U.S.
dollar equivalent amounts actually received or paid. Net currency gains and
losses from valuing foreign currency denominated assets and liabilities at
fiscal year-end exchange rates are reflected as a component of unrealized
appreciation on investments and foreign currencies.

Notes to Financial Statements         PRUDENTIAL PACIFIC INDEX FUND
- --------------------------------------------------------------------------------
Foreign security and currency transactions may involve certain considerations
and risks not typically associated with those of domestic origin as a result of,
among other factors, the possibility of political and economic instability and
the level of governmental supervision and regulation of foreign securities
markets.
Securities Transactions and Net Investment Income: Securities transactions are
recorded on the trade date. Realized gains and losses from investment and
foreign currency transactions are calculated on the identified cost basis.
Dividend income is recorded on the ex-dividend date and interest income is
recorded on the accrual basis. Expenses are recorded on the accrual basis which
may require the use of certain estimates by management.
Financial futures contracts: A financial futures contract is an agreement to
purchase (long) or sell (short) an agreed amount of securities at a set price
for delivery on a future date. Upon entering into a financial futures contract,
the Fund is required to pledge to the broker an amount of cash and/or other
assets equal to a certain percentage of the contract amount. This amount is
known as the 'initial margin.' Subsequent payments, known as 'variation margin,'
are made or received by the Fund each day, depending on the daily fluctuations
in the value of the underlying security. Such variation margin is recorded for
financial statement purposes on a daily basis as unrealized gain or loss. When
the contract expires or is closed, the gain or loss is realized and is presented
in the statement of operations as net realized gain (loss) on financial futures
contracts.
The Fund invests in financial futures contracts in order to hedge existing
portfolio securities, or securities the Fund intends to purchase, against
fluctuations in value. Under a variety of circumstances, the Fund may not
achieve the aniticipated benefits of the financial futures contracts and may
realize a loss. The use of futures transactions involves the risk of imperfect
correlation in movements in the price of futures contracts and the underlying
assets.
Dividends and Distributions: The Fund expects to pay dividends of net investment
income and distributions of net realized capital and currency gains, if any,
annually. Dividends and distributions are recorded on the ex-dividend date.
Income distributions and capital gain distributions are determined in accordance
with income tax regulations which may differ from generally accepted accounting
principles.
Taxes: For federal income tax purposes, each fund in the Company is treated as a
separate tax paying entity. It is the Fund'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 income to shareholders.
Therefore, no federal income tax provision is required.
Withholding taxes on foreign dividends, interest and capital gains have been
provided for in accordance with the Fund's understanding of the applicable
country's tax rules and rates.
Reclassification of Capital Accounts: The Fund accounts for and reports
distributions to shareholders in accordance with the American Institute of
Certified Public Accountants Statement of Position 93-2: Determination,
Disclosure, and Financial Statement Presentation of Income, Capital Gain, and
Return of Capital Distributions by Investment Companies. The effect of applying
this statement was to increase undistributed net investment income by $12,264,
decrease accumulated net realized loss on investments by $7,528, and decrease
paid-in-capital by $19,792 for certain expenses not being deductible for tax
purposes and for net realized foreign currency losses. Net investment income,
net realized gains and net assets were not affected by these changes.
- ------------------------------------------------------------
Note 2. Agreements
The Company has a management agreement with Prudential Investments Fund
Management LLC ('PIFM'). Pursuant to this agreement, PIFM has responsibility for
all investment advisory services and supervises the subadviser's performance of
such services. PIFM has entered into a subadvisory agreement with The Prudential
Investment Corporation ('PIC'); PIC furnishes investment advisory services in
connection with the management of the Company. PIFM pays for the cost of the
subadviser's services, the compensation of officers of the Company, occupancy
and certain clerical and bookkeeping costs of the Company. The Company bears all
other costs and expenses.
The management fee paid PIFM is computed daily and payable monthly at an annual
rate of .40 of 1% of the average daily net assets of the Fund.
PIFM has agreed to subsidize the operating expenses of the Fund so that total
Fund operating expenses do not exceed .60% on an annualized basis of the Fund's
average daily net assets. This voluntary waiver may be terminated at any time
without notice. For the year ended September 30, 1998, PIFM subsidized $281,526
of the expenses of the Fund (1.42% of average net assets $0.11 per share).

- --------------------------------------------------------------------------------
The Company had a distribution agreement with Prudential Securities Incorporated
('PSI'), which acted as the distributor of the Company through May 31, 1998.
Prudential Investment Management Services ('PIMS') became the Company's
distributor effective June 1, 1998 and is serving the Company under the same
terms and conditions as under the arragement with PSI. No distribution or
service fees are paid to PIMS as distributor of the Fund.
PSI, PIFM, PIC and PIMS are indirect, wholly owned subsidiaries of The
Prudential.
The Company, along with other affiliated registered investment companies (the
'Funds'), has a credit agreement (the 'Agreement') with an unaffiliated lender.
The maximum commitment under the Agreement is $200,000,000. Interest on any such
borrowings outstanding will be at market rates. The purpose of the Agreement is
to serve as an alternative source of funding for capital share redemptions. The
Fund did not borrow any amounts pursuant to the Agreement during the year ended
September 30, 1998. The Funds pay a commitment fee at an annual rate of .055 of
1% on the unused portion of the credit facility. The commitment fee is accrued
and paid quarterly on a pro rata basis by the Funds. The Agreement expired on
December 30, 1997 and has been extended through December 29, 1998 under the same
terms.
- ------------------------------------------------------------
Note 3. Other Transactions With Affiliates
Prudential Mutual Fund Services LLC ('PMFS'), a wholly owned subsidiary of PIFM,
serves as the Company's transfer agent. During the year ended September 30,
1998, the Fund incurred fees of approximately $200 for the services of PMFS.
Transfer agent fees and expenses in the Statement of Operations also include
certain out-of-pocket expenses paid to nonaffiliates.
- ------------------------------------------------------------
Note 4. Portfolio Securities
Purchases and sales of investment securities, other than short-term investments,
for the year ended September 30, 1998 were $1,057,544 and $302,382,
respectively.
The cost basis of investments for federal income tax purposes at September 30,
1998 was $24,985,283 and, accordingly, net unrealized depreciation for federal
income tax purposes was $8,886,187 (gross unrealized appreciation--$152,556;
gross unrealized depreciation--$9,038,743).
The Fund elected to treat approximately $20,600 of net currency losses and
$376,500 of net capital losses incurred during the 11-month period ended
September 30, 1998 as having been incurred in the following fiscal year.
During the year ended September 30, 1998, the Fund entered into financial

Report of Independent Accountants       PRUDENTIAL PACIFIC INDEX FUND
- --------------------------------------------------------------------------------
To the Shareholders and Board of Trustees
Prudential Index Series Fund--Prudential Pacific Index Fund:

In our opinion, the accompanying statement of assets and liabilities, including
the portfolio of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of Prudential Index Series
Fund--Prudential Pacific Index Fund (the 'Fund', one of the portfolios
constituting Prudential Index Series Fund) at September 30, 1998, the results of
its operations for the year then ended and the changes in its net assets and the
financial highlights for the year then ended and for the period September 24,
1997 (commencement of operations) through September 30, 1997, in conformity with
generally accepted accounting principles. These financial statements and
financial highlights (hereafter referred to as 'financial statements') are the
responsibility of the Fund's management; our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these financial statements in accordance with generally accepted
auditing standards which require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits, which included confirmation of securities at September 30, 1998 by
correspondence with the custodian and brokers, provide a reasonable basis for
the opinion expressed above.

Notes to Financial Statements                   PRUDENTIAL SMALL-CAP INDEX FUND
- --------------------------------------------------------------------------------
The Prudential Index Series Fund (the 'Company') is registered under the
Investment Company Act of 1940 as an open-end, diversified management investment
company. The Company was established as a Delaware business trust on May 11,
1992 and currently consists of five separate funds (the 'Funds'). Prudential
Small-Cap Index Fund (the 'Fund') commenced investment operations on October 1,
1997 when 1,860,203 shares of beneficial interest of the Fund were sold for
$18,602,031 to The Prudential Insurance Company of America ('The Prudential').
The Fund's investment objective is to provide investment results that correspond
to the price and yield performance of a broad-based index of small cap stocks.
The Fund currently uses the Standard & Poor's 600 Small Capitalization Stock
Price Index price for that purpose.
- ------------------------------------------------------------
Note 1. Accounting Policies

The following is a summary of significant accounting policies followed by the
Fund.

Securities Valuation: Securities, including options, warrants, futures contracts
and options thereon, for which the primary market is on a national securities
exchange, commodities exchange or board of trade or Nasdaq are valued at the
last sale price on such exchange or board of trade on the date of valuation or,
if there were no sales on such day, at the mean between the closing bid and
asked prices quoted on such day or at the bid price in the absence of an asked
price.

Securities that are actively traded in the over-the-counter market, including
listed securities for which the primary market is believed to be
over-the-counter, are valued by a principal market maker or independent pricing
agent.

U.S. Government securities for which market quotations are available shall be
valued at a price provided by an independent broker/dealer or pricing service.
Securities for which reliable market quotations are not available or for which
the pricing agent or principal market maker does not provide a valuation or
methodology or provides a valuation or methodology that, in the judgment of the
subadviser does not represent fair value, are valued at fair value as determined
under procedures established by the Trustees.

In connection with transactions in repurchase agreements, it is the Fund's
policy that its custodian or designated subcustodians under triparty repurchase
agreements, as the case may be, take possession of the underlying collateral
securities, the value of which exceeds 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 Net Investment Income: Securities transactions are
recorded on the trade date. Realized gains and losses on sales of securities are
calculated on the identified cost basis. Dividend income is recorded on the
ex-dividend date and interest income is recorded on the accrual basis. Expenses
are recorded on the accrual basis which may require the use of certain estimates
by management.

Financial Futures Contracts: A financial futures contract is an agreement to
purchase (long) or sell (short) an agreed amount of securities or commodities at
a set price for delivery on a future date. Upon entering into a financial
futures contract, the Fund is required to pledge to the broker an amount of cash
and/or other assets equal to a certain percentage of the contract amount. This
amount is known as the 'initial margin.' Subsequent payments, known as
'variation margin,' are made or received by the Fund each day, depending on the
daily fluctuations in the value of the underlying security or commodity. Such
variation margin is recorded for financial statement purposes on a daily basis
as unrealized gain or loss. When the contract expires or is closed, the gain or
loss is realized and is presented in the statement of operations as net realized
gain (loss) on financial futures contracts.

The Fund invests in financial futures contracts in order to hedge existing
portfolio securities, or securities the Fund intends to purchase, against
fluctuations in value. Under a variety of circumstances, the Fund may not
achieve the anticipated benefits of the financial futures contracts and may
realize a loss. The use of futures transactions involves the risk of imperfect
correlation in movements in the price of futures contracts and the underlying
assets.

Dividends and Distributions: Dividends and distributions of the Fund are
declared in cash and automatically reinvested in additional shares of the Fund.
The Fund will declare and distribute its net investment income and net capital
gains, if any, at least annually. Dividends and distributions are recorded on
the ex-dividend date.

Income distributions and capital gain distributions are determined in accordance
with income tax regulations which may differ from generally accepted accounting
principles.

Federal Income Taxes: It is the Fund's policy to meet the requirements of the
Internal Revenue Code applicable to regulated investment companies

and to distribute all of its taxable net investment income and net capital
gains, if any, to its shareholders. Therefore, no federal income tax provision
is required.

Withholding taxes on foreign dividends have been provided for in accordance with
the Fund's understanding of the applicable country's tax rules and rates.

Deferred Offering Expenses: Approximately $19,600 of costs were incurred in
connection with the offering and initial registration of the Fund and have been
deferred and are being amortized ratably over a period of twelve months from the
date each of the Funds commenced investment operations. At September 30, 1998,
deferred offering expenses were fully amortized.

Reclassification of Capital Accounts: The Fund accounts and reports for
distributions to shareholders in accordance with Statement of Position 93-2:
Determination, Disclosure, and Financial Statement Presentation of Income,
Capital Gain, and Return of Capital Distributions by Investment Companies. The
effect of applying this statement was to increase undistributed net investment
income by $19,620 and decrease paid-in capital in excess of par by $19,620. Net
realized gains and net assets were not affected by this change.
- ------------------------------------------------------------
Note 2. Agreements

The Fund has a management agreement with Prudential Investment Fund Management
LLC ('PIFM' or the 'Manager'.) Pursuant to this agreement PIFM has
responsibility for all investment advisory services. PIFM has entered into a
subadvisory agreement with The Prudential Investment Corporation ('PIC'). PIC,
subject to the supervision of PIFM, manages the assets of the Fund in accordance
with its investment objective and policies. PIFM pays for the costs and expenses
attributable to the subadvisory agreement and the salaries and expenses of all
personnel of the Fund except for fees and expenses of unaffiliated Trustees. The
management fee paid to PIFM is computed daily and payable monthly at an annual
rate of .30 of 1% of the Fund's average daily net assets.

PIFM has agreed to reimburse the Fund so that total operating expenses do not
exceed .50% of the average net assets of the Fund for the fiscal year ending
September 30, 1998. This voluntary waiver may be terminated at any time without
notice. For the period ended September 30, 1998, PIFM subsidized $268,030 for
the expenses of the Fund (1.18% of the average net assets of the Fund/$.11 per
share.)

Prudential Securities Incorporated ('PSI') acted as the distributor of the
Fund's shares through May 31, 1998. Prudential Investment Management Services
('PIMS') became the distributor of the Fund effective June 1, 1998 and is
serving under the same terms and conditions as under the agreement with PSI.
Under the distribution agreement, PSI and PIMS incurred the expenses of
distributing the Fund's shares, none of which is reimbursed or paid for by the
Fund.

PIC, PIFM, PIMS and PSI are wholly owned subsidiaries of The Prudential
Insurance Company of America.

The Fund, along with other affiliated registered investment companies (the
'funds'), has a credit agreement (the 'Agreement') with an unaffiliated lender.
The maximum commitment under the Agreement is $200,000,000. Interest on any such
borrowings outstanding will be at market rates. The purpose of the Agreement is
to serve as an alternative source of funding for capital share redemptions. The
Fund did not borrow any amounts pursuant to the Agreement during the period
ended September 30, 1998. The funds pay a commitment fee at an annual rate of
 .055 of 1% on the unused portion of the credit facility. The commitment fee is
accrued and paid quarterly on a pro rata basis by the funds. The Agreement
expires on December 29, 1998.
- ------------------------------------------------------------
Note 3. Other Transactions With Affiliates

Prudential Mutual Fund Services LLC ('PMFS'), a wholly owned subsidiary of PIFM,
serves as the Fund's transfer agent. During the year ended September 30, 1998,
the Fund incurred fees of approximately $3,000 for the services of PMFS. As of
September 30, 1998, approximately $500 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 nonaffiliates.
- ------------------------------------------------------------
Note 4. Portfolio Securities

Purchases and sales of portfolio securities, excluding short-term investments,
for the year ended September 30, 1998 aggregated $35,189,048 and $11,302,768,
respectively.

On September 30, 1998, the Fund held one purchased financial futures contract on
the S&P Midcap 400 Index expiring December 30, 1998. The cost of such contract
was $1,247,950. The value of the contract on September 30, 1998 was $1,244,800,
thereby resulting in an unrealized loss of $3,150.

The cost basis of investments for federal income tax purposes is $25,171,284
and, accordingly, as of September 30, 1998, net unrealized appreciation for
federal income tax purposes was $5,046,425 (gross unrealized
appreciation--$1,222,048; gross unrealized depreciation--$6,268,473).

To the Shareholders and Board of Trustees of
Prudential Index Series Fund--Prudential Small-Cap Index Fund


In our opinion, the accompanying statement of assets and liabilities, including
the portfolio of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of Prudential Index Series
Fund--Prudential Small-Cap Index Fund (the 'Fund,' one of the portfolios
constituting Prudential Index Series Fund) at September 30, 1998 and the results
of its operations, the changes in its net assets and the financial highlights
for the period October 1, 1997 (commencement of operations) through September
30, 1998, in conformity with generally accepted accounting principles. These
financial statements and financial highlights (hereafter referred to as
'financial statements') are the responsibility of the Fund's management; our
responsibility is to express an opinion on these financial statements based on
our audit. We conducted our audit of these financial statements in accordance
with generally accepted auditing standards which require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audit, which included confirmation of securities at
September 30, 1998 by correspondence with the custodian and brokers, provides a
reasonable basis for the opinion expressed above.

- --------------------------------------------------------------------------------
The Prudential Index Series Fund (the 'Company'), formerly the Prudential Dryden
Fund is registered under the Investment Company Act of 1940 as an open-end,
diversified management investment company. The Company was established as a
Delaware business trust on May 11, 1992 and currently consists of five separate
funds, one of which is the Prudential Stock Index Fund (the 'Fund').

The Company had no operations until July 7, 1992 when 10,000 shares of
beneficial interest of the Company were sold for $100,000 to Prudential
Institutional Fund Management, Inc. Investment operations of the Fund commenced
on November 5, 1992. The Fund's investment objective is to provide investment
results that correspond to the price and yield performance of Standard & Poor's
500 Composite Stock Price Index.
- ------------------------------------------------------------
Note 1. Accounting Policies
The following is a summary of significant accounting policies followed by the
Fund.

Securities Valuation: Securities, including options, warrants, futures contracts
and options thereon, for which the primary market is on a national securities
exchange, commodities exchange or board of trade or Nasdaq are valued at the
last sale price on such exchange or board of trade on the date of valuation or,
if there were no sales on such day, at the mean between the closing bid and
asked prices quoted on such day or at the bid price in the absence of an asked
price.

Securities that are actively traded in the over-the-counter market, including
listed securities for which the primary market is believed to be
over-the-counter, are valued by a principal market maker or independent pricing
agent.

U.S. Government securities for which market quotations are available shall be
valued at a price provided by an independent broker/dealer or pricing service.

Securities for which reliable market quotations are not available or for which
the pricing agent or principal market maker does not provide a valuation or
methodology or provides a valuation or methodology that, in the judgment of the
subadvisers, does not represent fair value, are valued at fair value as
determined under procedures established by the Trustees.

In connection with transactions in repurchase agreements, it is the Fund's
policy that its custodian or designated subcustodians, under triparty repurchase
agreements, as the case may be take possession of the underlying collateral
securities, the value of which exceeds 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 Net Investment Income: Securities transactions are
recorded on the trade date. Realized gains and losses on sales of securities are
calculated on the identified cost basis. Dividend income is recorded on the
ex-dividend date and interest income is recorded on the accrual basis. Expenses
are recorded on the accrual basis which may require the use of certain estimates
by management.

Net investment income (other than transfer agent 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.
Transfer agent fees are allocated based on shareholder activity and number of
accounts for each class.

Financial Futures Contracts: A financial futures contract is an agreement to
purchase (long) or sell (short) an agreed amount of securities at a set price
for delivery on a future date. Upon entering into a financial futures contract,
the Fund is required to pledge to the broker an amount of cash and/or other
assets equal to a certain percentage of the contract amount. This amount is
known as the 'initial margin.' Subsequent payments, known as 'variation margin,'
are made or received by the Fund each day, depending on the daily fluctuations
in the value of the underlying security. Such variation margin is recorded for
financial statement purposes on a daily basis as unrealized gain or loss. When
the contract expires or is closed, the gain or loss is realized and is presented
in the statement of operations as net realized gain (loss) on financial futures
contracts.

The Fund invests in financial futures contracts in order to hedge existing
portfolio securities, or securities the Fund intends to purchase, against
fluctuations in value. Under a variety of circumstances, the Fund may not
achieve the anticipated benefits of the financial futures contracts and may
realize a loss. The use of futures transactions involves the risk of imperfect
correlation in movements in the price of futures contracts and the underlying
assets.

Dividends and Distributions: Dividends and distributions of the Fund are
declared in cash and automatically reinvested in additional shares of the Fund.
The Fund will declare and distribute its net investment income and net capital
gains, if any, at least annually. Dividends and distributions are recorded on
the ex-dividend date.

- --------------------------------------------------------------------------------
Income distributions and capital gain distributions are determined in accordance
with income tax regulations which may differ from generally accepted accounting
principles.

Taxes: It is the Fund'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 investment income and net capital gains, if
any, to its shareholders. Therefore, no federal income tax provision is
required.

Withholding taxes on foreign dividends have been provided for in accordance with
the Fund's understanding of the applicable country's tax rules and rates.

Deferred Organizational Expenses: Approximately $450,000 of costs were incurred
in connection with the organization and initial registration of the Company and
such amount was deferred and amortized over a 60-month period ending October
1997.

Reclassification of Capital Accounts: The Fund accounts and reports for
distributions to shareholders in accordance with the American Institute of
Certified Public Accountants, Statement of Position 93-2: Determination,
Disclosure, and Financial Statement Presentation of Income, Capital Gain and
Return of Capital Distributions by Investment Companies. The effect of applying
this statement was to increase undistributed net investment income and decrease
accumulated net realized gain on investments and foreign currencies by $240,641.
Net realized gains and net assets were not affected by this change.
- ------------------------------------------------------------
Note 2. Agreements

The Fund has a management agreement with Prudential Investments Fund Management
('PIFM'). Pursuant to this agreement PIFM has responsibility for all investment
advisory services. PIFM has a subadvisory agreement with The Prudential
Investment Corporation ('PIC'). PIC, subject to the supervision of PIFM, manages
the assets of the Fund in accordance with its investment objective and policies.
PIFM pays for the costs and expenses attributable to the subadvisory agreement

ended September 30, 1998. The Funds pay a commitment fee at an annual rate of
 .055 of 1% on the unused portion of the credit facility. The commitment fee is

The Shareholders and Board of Trustees of
Prudential Index Series Fund--Prudential Stock Index Fund

In our opinion, the accompanying statement of assets and liabilities, including
the portfolio of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of Prudential Index Series
Fund--Prudential Stock Index Fund (the 'Fund,' one of the portfolios
constituting Prudential Index Series Fund) (formerly The Prudential Dryden
Fund--Prudential Stock Index Fund) at September 30, 1998, the results of its
operations for the year then ended, the changes in its net assets and the
financial highlights for each of the two years in the period then ended, in
conformity with generally accepted accounting principles. These financial
statements and financial highlights (hereafter referred to as 'financial
statements') are the responsibility of the Fund's management; our responsibility
is to express an opinion on these financial statements based on our audits. We
conducted our audits of these financial statements in accordance with generally
accepted auditing standards which require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements, assessing
the accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits, which included confirmation of securities at September 30, 1998 by
correspondence with the custodian and brokers, provide a reasonable basis for
the opinion expressed above. The accompanying financial highlights for each of
the three periods in the period ended September 30, 1996 were audited by other
independent accountants, whose opinion dated November 13, 1996 was unqualified.

Notes to Financial Statements                PRUDENTIAL INDEX SERIES FUND
(Unaudited)                                  PRUDENTIAL STOCK INDEX FUND
- --------------------------------------------------------------------------------
The Prudential Index Series Fund (the 'Company'), formerly the Prudential Dryden
Fund is registered under the Investment Company Act of 1940 as an open-end,
diversified management investment company. The Company was established as a
Delaware business trust on May 11, 1992 and currently consists of five separate
funds, one of which is the Prudential Stock Index Fund (the 'Fund').
The Company had no operations until July 7, 1992 when 10,000 shares of
beneficial interest of the Company were sold for $100,000 to Prudential
Institutional Fund Management, Inc. Investment operations of the Fund commenced
on November 5, 1992. The Fund's investment objective is to provide investment
results that correspond to the price and yield performance of Standard & Poor's
500 Composite Stock Price Index.
- ------------------------------------------------------------
Note 1. Accounting Policies
The following is a summary of significant accounting policies followed by the
Fund.
Securities Valuation: Securities, including options, warrants, futures contracts
and options thereon, for which the primary market is on a national securities
exchange, commodities exchange or board of trade or Nasdaq are valued at the
last sale price on such exchange or board of trade on the date of valuation or,
if there were no sales on such day, at the mean between the closing bid and
asked prices quoted on such day or at the bid price in the absence of an asked
price.
Securities that are actively traded in the over-the-counter market, including
listed securities for which the primary market is believed to be
over-the-counter, are valued by a principal market maker or independent pricing
agent.
U.S. Government securities for which market quotations are available shall be
valued at a price provided by an independent broker/dealer or pricing service.
Securities for which reliable market quotations are not available or for which
the pricing agent or principal market maker does not provide a valuation or
methodology or provides a valuation or methodology that, in the judgment of the
subadvisers, does not represent fair value, are valued at fair value as
determined under procedures established by the Trustees.
Repurchase Agreements: In connection with transactions in repurchase agreements,
it is the Fund's policy that its custodian or designated subcustodians, under
triparty repurchase agreements, as the case may be take possession of the
underlying collateral securities, the value of which exceeds 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 Net Investment Income: Securities transactions are
recorded on the trade date. Realized gains and losses on sales of securities are
calculated on the identified cost basis. Dividend income is recorded on the
ex-dividend date and interest income is recorded on the accrual basis. Expenses
are recorded on the accrual basis which may require the use of certain estimates
by management.
Net investment income (other than transfer agent 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.
Transfer agent fees are allocated based on shareholder activity and number of
accounts for each class.
Financial Futures Contracts: A financial futures contract is an agreement to
purchase (long) or sell (short) an agreed amount of securities at a set price
for delivery on a future date. Upon entering into a financial futures contract,
the Fund is required to pledge to the broker an amount of cash and/or other
assets equal to a certain percentage of the contract amount. This amount is
known as the 'initial margin.' Subsequent payments, known as 'variation margin,'
are made or received by the Fund each day, depending on the daily fluctuations
in the value of the underlying security. Such variation margin is recorded for
financial statement purposes on a daily basis as unrealized gain or loss. When
the contract expires or is closed, the gain or loss is realized and is presented
in the statement of operations as net realized gain (loss) on financial futures
contracts.
The Fund invests in financial futures contracts in order to hedge existing
portfolio securities, or securities the Fund intends to purchase, against
fluctuations in value. Under a variety of circumstances, the Fund may not
achieve the anticipated benefits of the financial futures contracts and may
realize a loss. The use of futures transactions involves the risk of imperfect
correlation in movements in the price of futures contracts and the underlying
assets.
Dividends and Distributions: Dividends and distributions of the Fund are
declared in cash and automatically reinvested in additional shares of the Fund.
The Fund will declare and distribute its net investment income and net capital
gains, if any, at least annually. Dividends and distributions are recorded on
the ex-dividend date.

(Unaudited)                               PRUDENTIAL STOCK INDEX FUND
- --------------------------------------------------------------------------------
Income distributions and capital gain distributions are determined in accordance
with income tax regulations which may differ from generally accepted accounting
principles.
Taxes: It is the Fund'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 investment income and net capital gains, if
any, to its shareholders. Therefore, no federal income tax provision is
required.
Withholding taxes on foreign dividends have been provided for in accordance with
the Fund's understanding of the applicable country's tax rules and rates.
- ------------------------------------------------------------
Note 2. Agreements
The Fund has a management agreement with Prudential Investments Fund Management
('PIFM'). Pursuant to this agreement PIFM has responsibility for all investment
advisory services. PIFM has a subadvisory agreement with The Prudential
Investment Corporation ('PIC'). PIC, subject to the supervision of PIFM, manages
the assets of the Fund in accordance with its investment objective and policies.
PIFM pays for the costs and expenses attributable to the subadvisory agreement
and the salaries and expenses of all personnel of the Fund except for fees and
expenses of unaffiliated Trustees. The management fee paid to PIFM is computed
daily and payable monthly at an annual rate of .30 of 1% of the Fund's average
daily net assets.
PIFM has agreed to reimburse the Fund so that total operating expenses do not
exceed .40% of the average net assets for Class Z shares of the Fund. PIFM has
agreed to reimburse the Fund so that total operating expenses do not exceed .30%
of the average net assets for Class I shares of the Fund. This voluntary waiver
may be terminated at any time without notice. For the six months ended March 31,
1999, PIFM subsidized $330,793 of the expenses of the Fund (.02% of the average
net assets of the Fund $.006 per share).
Prudential Securities Incorporated ('PSI') acted as the distributor of the
Fund's shares through May 31, 1998. Prudential Investment Management Services
('PIMS') became the distributor of the Fund effective June 1, 1998 and is
serving under the same terms and conditions as under the agreement with PSI.
Under the distribution agreement, PSI and PIMS incurred the expenses of
distributing the Fund's shares, none of which is reimbursed or paid for by the
Fund.
PIC, PIFM, PIMS and PSI are wholly owned subsidiaries of The Prudential
Insurance Company of America.
As of March 11, 1999, the Fund, along with other affiliated registered
investment companies (the 'Funds'), entered into a syndicated credit agreement
('SCA') with an unaffiliated lender. The maximum commitment under the SCA is $1
billion. The Funds pay a commitment fee at an annual rate of .065 of 1% on the
unused portion of the credit facility, which is accrued and paid quarterly on a
pro rata basis by the Funds. The SCA expires on March 9, 2000. Prior to March
11, 1999, the Funds had a credit agreement with a maximum commitment of
$200,000,000. The commitment fee was .055 of 1% on the unused portion of the
credit facility. The Fund did not borrow any amounts pursuant to either
agreement during the six months ended March 31, 1999. The purpose of the
agreements are to serve as an alternative source of funding for capital share
redemptions.
- ------------------------------------------------------------
Note 3. Other Transactions With Affiliates
Prudential Mutual Fund Services LLC ('PMFS'), a wholly owned subsidiary of PIFM,
serves as the Fund's transfer agent. During the six months ended March 31, 1999,
the Fund incurred fees of approximately $390,000 for the services of PMFS. As of
March 31, 1999, approximately $75,000 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 nonaffiliates.
- ------------------------------------------------------------
Note 4. Portfolio Securities
Purchases and sales of portfolio securities, excluding short-term investments,
for the six months ended March 31, 1999 aggregated $316,624,301 and $21,268,200,
respectively.
On March 31, 1999, the Fund held 236 purchased financial futures contracts on
the S&P 500 Index expiring by June 1999. The cost of such contracts was
$77,439,450. The value of such contracts on March 31, 1999 was $76,304,700,
thereby resulting in an unrealized loss of $1,134,750.
The cost basis of investments for federal income tax purposes was $1,250,970,994
and, accordingly, as of March 31, 1999, net unrealized appreciation for federal
income tax purposes was $407,000,598 (gross unrealized
appreciation--$441,008,887; gross unrealized depreciation--$34,008,289).

uninvested cash balances into a single joint account, the daily aggregate
balance of which is invested in one or more repurchase agreements collateralized
by U.S. Treasury or federal agency obligations. At March 31, 1999, the Fund had

Notes to Financial Statements (Unaudited)          PRUDENTIAL EUROPE INDEX FUND
- --------------------------------------------------------------------------------
Prudential Index Series Fund, (the 'Company'), is registered under the
Investment Company Act of 1940 as an open-end diversified management investment
company. The Company was established as a Delaware business trust on May 11,
1992 and currently consists of five separate Funds. Prudential Europe Index Fund
(the 'Fund') commenced investment operations on October 1, 1997 when 1,500,000
shares of beneficial interest of the Fund were sold for $15,000,000 to The
Prudential Insurance Company of America ('The Prudential').

The Fund's investment objective is to seek to provide investment results that
correspond to the price and yield performance of a broad-based index of
securities of European issuers, currently the Morgan Stanley Capital
International Europe Index.
- ------------------------------------------------------------
Note 1. Accounting Policies

The following is a summary of significant accounting policies followed by the
Company and the Fund in the preparation of its financial statements.

Securities Valuation: Securities for which the primary market is on an exchange,
are valued at the last sale price on such exchange on the day of valuation or,
if there were no sales on such day, at the mean between the last bid and asked
prices on such day or at the bid price in the absence of an asked price.
Securities that are actively traded in the over-the-counter market, including
listed securities for which the primary market is believed to be
over-the-counter, are valued by an independent pricing agent or a principal
market maker. Securities for which reliable market quotations are not available
or for which the pricing agent or principal market maker does not provide a
valuation or methodology or provides a valuation or methodology that, in the
judgment of the subadviser, does not represent fair value, are valued at fair
value as determined by procedures established by the Company's Trustees.

Short-term securities which mature in more than 60 days are valued at current
market quotations. Short-term securities which mature in 60 days or less are
valued at amortized cost.

In connection with transactions in repurchase agreements with U.S. financial
institutions, it is the Company's policy that its custodian or designated
subcustodians, under triparty repurchase agreements, as the case may be, takes
possession of the underlying collateral securities, the value of which exceeds
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.

Foreign Currency Translation: The books and records of the Fund are maintained
in U.S. dollars. Foreign currency amounts are translated into U.S. dollars on
the following basis:

(i) market value of investment securities, other assets and liabilities--at the
closing rates of exchange;

(ii) purchases and sales of investment securities, income and expenses--at the
rate of exchange prevailing on the respective dates of such transactions.

Although the net assets of the Fund are presented at the foreign exchange rates
and market values at the close of the fiscal period, the Fund does not isolate
that portion of the results of operations arising as a result of changes in the
foreign exchange rates from the fluctuations arising from changes in the market
prices of securities held at the end of the fiscal period. Similarly, the Fund
does not isolate the effect of changes in foreign exchange rates from the
fluctuations arising from changes in the market prices of long-term securities
sold during the fiscal period. Accordingly, realized foreign currency gains
(losses) are included in the reported net realized gains on investment
transactions.

Net realized losses on foreign currency transactions represent net foreign
exchange gains or losses from forward currency contracts, disposition of foreign
currencies, currency gains or losses realized between the trade and settlement
dates on security transactions, and the difference between the amounts of
interest, dividends and foreign taxes recorded on the Fund's books and the U.S.
dollar equivalent amounts actually received or paid. Net currency gains and
losses from valuing foreign currency denominated assets and liabilities at
fiscal period end exchange rates are reflected as a component of unrealized
appreciation on investments and foreign currencies.

Foreign security and currency transactions may involve certain considerations
and risks not typically associated with those of domestic origin as a result of,
among other factors, the possibility of political and economic instability and
the level of governmental supervision and regulation of foreign securities
markets.

Forward Currency Contracts: A forward currency contract is a commitment to
purchase or sell a foreign currency at a future date at a negotiated forward
rate. The Fund enters into forward currency contracts in order to hedge its
exposure to changes in foreign currency exchange rates on its foreign
- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------
portfolio holdings or on specific receivables and payables denominated in a
foreign currency. The contracts are valued daily at current exchange rates and
any unrealized gain or loss is included in net unrealized appreciation or
depreciation on investments. Gain or loss is realized on settlement date of the
contract equal to the difference between settlement value of the original and
renegotiated forward contracts. This gain or loss, if any, is included in net
realized gain (loss) on foreign currency transactions. Risks may arise upon
entering into these contracts from the potential inability of the counter
parties to meet the terms of their contracts.

Financial Futures Contracts: A financial futures contract is an agreement to
purchase (long) or sell (short) an agreed amount of securities or commodities at
a set price for delivery on a future date. Upon entering into a financial
futures contract, the Fund is required to pledge to the broker an amount of cash
and/or other assets equal to a certain percentage of the contract amount. This
amount is known as the 'initial margin.' Subsequent payments, known as
'variation margin,' are made or received by the Fund each day, depending on the
daily fluctuations in the value of the underlying security. Such variation
margin is recorded for financial statement purposes on a daily basis as
unrealized gain or loss. When the contract expires or is closed, the gain or
loss is realized and is presented in the statement of operations as net realized
gain (loss) on financial futures contracts.

The Fund invests in financial futures contracts in order to hedge existing
portfolio securities, or securities the Fund intends to purchase, against
fluctuations in value. Under a variety of circumstances, the Fund may not
achieve the anticipated benefits of the financial futures contracts and may
realize a loss. The use of futures transactions involves the risk of imperfect
correlation in movements in the price of futures contracts and the underlying
assets.

Securities Transactions and Net Investment Income: Securities transactions are
recorded on the trade date. Realized gains and losses from investment and
foreign currency transactions are calculated on the identified cost basis.
Dividend income is recorded on the ex-dividend date and interest income is
recorded on an accrual basis. Expenses are recorded on the accrual basis which
may require the use of certain estimates by management.

Dividends and Distributions: The Fund expects to pay dividends of net investment
income and distributions of net realized capital and currency gains, if any,
annually. Dividends and distributions are recorded on the ex-dividend date.

Income distributions and capital gain distributions are determined in accordance
with income tax regulations which may differ from generally accepted accounting
principles.

Taxes: It is the Fund's policy to meet the requirements of the Internal Revenue
Code applicable to regulated investment companies and to distribute all of its
taxable income to shareholders. Therefore, no federal income tax provision is
required.

Withholding taxes on foreign dividends, interest and capital gains have been
provided for in accordance with the Fund's understanding of the applicable
country's tax rules and rates.

Reclassification of Capital Accounts: The Fund accounts for and reports
distributions to shareholders in accordance with American Institute of Certified
Public Accountants (AICPA), Statement of Position 93-2: Determination,
Disclosure, and Financial Statement Presentation of Income, Capital Gain, and
Return of Capital Distributions by Investment Companies. The effect of applying
this Statement of Position was to reclassify $13,050 of foreign currency losses
from accumulated net realized gains on investments to distributions in excess of
net investment income. Net investment income, net realized gains and net assets
were not affected by this change.
- ------------------------------------------------------------
Note 2. Agreements

The Company has a management agreement with Prudential Investments Fund
Management LLC ('PIFM'). Pursuant to this agreement, PIFM has responsibility for
all investment advisory services and supervises the subadviser's performance of
such services. PIFM has entered into a subadvisory agreement with The Prudential
Investment Corporation ('PIC'); PIC furnishes investment advisory services in
connection with the management of the Fund. PIFM pays for the cost of the
subadviser's services, the compensation of officers of the Company, occupancy
and certain clerical and bookkeeping costs of the Company. The Company bears all
other costs and expenses.

The management fee paid to PIFM is computed daily and payable monthly at an
annual rate of .40 of 1% of the average daily net assets of the Fund.

PIFM has agreed to subsidize the operating expenses of the Fund so that total
Fund operating expenses do not exceed .60% on an annualized basis of the Fund's
average daily net assets. This voluntary waiver may be terminated at any time
without notice. For the six months ended March

- --------------------------------------------------------------------------------
31, 1999, PIFM subsidized $163,433 of the expenses of the Fund (1.55% of average
daily net assets, annualized, or $0.09 per share).

The Fund has a distribution agreement with PIMS, which acts as the distributor
of the Fund. No distribution or service fees are paid to PIMS as distributor of
the Fund.

PIFM, PIMS and PIC are wholly owned subsidiaries of The Prudential.

As of March 11, 1999, the Fund, along with other unaffiliated registered
investment companies (the 'Funds'), entered into a syndicated agreement ('SCA')
with an unaffiliated lender. The maximum commitment under the SCA is $1 billion.
The Funds pay a commitment fee at an annual rate of .065 of 1% on the unused
portion of the credit facility, which is accrued and paid quarterly on a pro
rata basis by the Funds. The SCA expires on March 9, 2000. Prior to March 11,
1999, the Funds had a credit agreement with a maximum commitment of
$200,000,000. The commitment fee was .055 of 1% on the unused portion of the
credit facility. The Fund did not borrow any amounts pursuant to either
agreement during the six months ended March 31, 1999. The purpose of the
agreements is to serve as an alternative source of funding for capital share
redemptions.
- ------------------------------------------------------------
Note 3. Other Transactions With Affiliates

Prudential Mutual Fund Services LLC ('PMFS'), a wholly owned subsidiary of PIFM,
serves as the Company's transfer agent. During the six months ended March 31,
1999, the Fund incurred fees of approximately $1,800 for the services of PMFS.
As of March 31, 1999, approximately $400 of such fees were due to PMFS. Transfer
agent fees and expenses in the Statement of Operations include certain
out-of-pocket expenses paid to nonaffiliates.
- ------------------------------------------------------------
Note 4. Portfolio Securities

Purchases and sales of investment securities, other than short-term investments,
for the six months ended March 31, 1999 were $1,936,525 and $249,378,
respectively.

The United States federal income tax cost basis of the Fund's investments at
March 31, 1999 was $19,126,322 and, accordingly, net unrealized appreciation for
federal income tax purposes was $3,175,736 (gross unrealized
appreciation--$4,168,821; gross unrealized depreciation--$993,085).

At March 31, 1999, the Fund had open buys of 100 EUROTOP and 40 FTSE 100
financial futures contracts expiring on June 19, 1999.

Notes to Financial Statements (Unaudited)         PRUDENTIAL PACIFIC INDEX FUND
- --------------------------------------------------------------------------------
Prudential Index Series Fund, (the 'Company') is registered under the Investment
Company Act of 1940 as an open-end, diversified management investment company.
The Company was established as a Delaware business trust on May 11, 1992 and
currently consists of five separate funds. Prudential Pacific Index Fund (the
'Fund') commenced investment operations on September 24, 1997 when 2,500,020
shares of beneficial interest of the Fund were sold for $25,000,200 to The
Prudential Insurance Company of America ('The Prudential'). The investment
objective of the Fund is to seek to provide investment results that correspond
to the price and yield performance of a broad-based index of securities of
issuers in the Pacific region, currently the Morgan Stanley Capital
International Pacific Free Index ('MSCI-PFI').
- ------------------------------------------------------------
Note 1. Accounting Policies

The following is a summary of significant accounting policies followed by the
Company and the Fund in the preparation of its financial statements.

Securities Valuation: Securities for which the primary market is on an exchange
are valued at the last sale price on such exchange on the day of valuation or,
if there was no sale on such day, at the mean between the last bid and asked
prices on such day or at the bid price in the absence of an asked price.
Securities that are actively traded in the over-the-counter market, including
listed securities for which the primary market is believed to be
over-the-counter, are valued by an independent pricing agent or a principal
market maker. U.S. Government securities for which market quotations are readily
available are valued at a price provided by an independent broker/dealer or
pricing service. Securities for which reliable market quotations are not
available or for which the pricing agent or principal market maker does not
provide a valuation or methodology or provides a valuation or methodology that,
in the judgment of the subadviser, does not represent fair value, are valued at
fair value as determined by procedures established by the Company's Trustees.

Due to current market conditions, the Company's Board of Directors reduced the
valuation of securities held in Malaysian currency by 15 percent effective
February 26, 1999.

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.

Repurchase Agreements: In connection with transactions in repurchase agreements
with U.S. financial institutions, it is the Company's policy that its custodian
or designated subcustodians under triparty repurchase agreements, as the case
may be, takes possession of the underlying collateral securities, the value of
which exceeds 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.

All securities are valued as of 4:15 p.m., New York time.

Foreign Currency Translation: The books and records of the Fund are maintained
in U.S. dollars. Foreign currency amounts are translated into U.S. dollars on
the following basis:

(i) market value of investment securities, other assets and liabilities--at the
closing rates of exchange;

(ii) purchases and sales of investment securities, income and expenses--at the
rate of exchange prevailing on the respective dates of such transactions.

Although the net assets of the Fund are presented at the foreign exchange rates
and market values at the close of the period, the Fund does not isolate that
portion of the results of operations arising as a result of changes in the
foreign exchange rates from the fluctuations arising from changes in the market
prices of securities held at the end of the period. Similarly, the Fund does not
isolate the effect of changes in foreign exchange rates from the fluctuations
arising from changes in the market prices of long-term debt securities sold
during the period. Accordingly, realized foreign currency gains (losses) are
included in the reported net realized gains on investment transactions.

Net realized losses on foreign currency transactions represent net foreign
exchange gains or losses from forward currency contracts, disposition of foreign
currencies, currency gains or losses realized between the trade and settlement
dates on security transactions, and the difference between the amounts of
interest, dividends and foreign taxes recorded on the Fund's books and the U.S.
dollar equivalent amounts actually received or paid. Net currency gains and
losses from valuing foreign currency denominated assets and liabilities at
period-end exchange rates are reflected as a component of unrealized
appreciation on investments and foreign currencies.

Foreign security and currency transactions may involve certain considerations
and risks not typically associated with those of domestic origin as a

- --------------------------------------------------------------------------------
result of, among other factors, the possibility of political and economic
instability and the level of governmental supervision and regulation of foreign
securities markets.

Securities Transactions and Net Investment Income: Securities transactions are
recorded on the trade date. Realized gains and losses from investment and
foreign currency transactions are calculated on the identified cost basis.
Dividend income is recorded on the ex-dividend date and interest income is
recorded on the accrual basis. Expenses are recorded on the accrual basis which
may require the use of certain estimates by management.

Financial futures contracts: A financial futures contract is an agreement to
purchase (long) or sell (short) an agreed amount of securities at a set price
for delivery on a future date. Upon entering into a financial futures contract,
the Fund is required to pledge to the broker an amount of cash and/or other
assets equal to a certain percentage of the contract amount. This amount is
known as the 'initial margin.' Subsequent payments, known as 'variation margin,'
are made or received by the Fund each day, depending on the daily fluctuations
in the value of the underlying security. Such variation margin is recorded for
financial statement purposes on a daily basis as unrealized gain or loss. When
the contract expires or is closed, the gain or loss is realized and is presented
in the statement of operations as net realized gain (loss) on financial futures
contracts.

The Fund invests in financial futures contracts in order to hedge existing
portfolio securities, or securities the Fund intends to purchase, against
fluctuations in value. Under a variety of circumstances, the Fund may not
achieve the anticipated benefits of the financial futures contracts and may
realize a loss. The use of futures transactions involves the risk of imperfect
correlation in movements in the price of futures contracts and the underlying
assets.

Dividends and Distributions: The Fund expects to pay dividends of net investment
income and distributions of net realized capital and currency gains, if any,
annually. Dividends and distributions are recorded on the ex-dividend date.

Income distributions and capital gain distributions are determined in accordance
with income tax regulations which may differ from generally accepted accounting
principles.

Taxes: For federal income tax purposes, each fund in the Company is treated as a
separate tax paying entity. It is the Fund'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 income to shareholders.
Therefore, no federal income tax provision is required.

Withholding taxes on foreign dividends, interest and capital gains have been
provided for in accordance with the Fund's understanding of the applicable
country's tax rules and rates.

Reclassification of Capital Accounts: The Fund accounts for and reports
distributions to shareholders in accordance with the American Institute of
Certified Public Accountants Statement of Position 93-2: Determination,
Disclosure, and Financial Statement Presentation of Income, Capital Gain, and
Return of Capital Distributions by Investment Companies. The effect of applying
this statement was to decrease undistributed net investment income and to
decrease accumulated net realized loss on investments by $44,576, relating to
net realized foreign currency losses. Net investment income, net realized gains
and net assets were not affected by these changes.
- ------------------------------------------------------------
Note 2. Agreements

The Company has a management agreement with Prudential Investments Fund
Management LLC ('PIFM'). Pursuant to this agreement, PIFM has responsibility for
all investment advisory services and supervises the subadviser's performance of
such services. PIFM has entered into a subadvisory agreement with The Prudential
Investment Corporation ('PIC'); PIC furnishes investment advisory services in
connection with the management of the Company. PIFM pays for the cost of the
subadviser's services, the compensation of officers of the Company, occupancy
and certain clerical and bookkeeping costs of the Company. The Company bears all
other costs and expenses.

The management fee paid PIFM is computed daily and payable monthly at an annual
rate of .40 of 1% of the average daily net assets of the Fund.

PIFM has agreed to subsidize the operating expenses of the Fund so that total
Fund operating expenses do not exceed .60% on an annualized basis of the Fund's
average daily net assets. This voluntary waiver may be terminated at any time
without notice. For the six months ended March 31, 1999, PIFM subsidized
$113,310 of the expenses of the Fund (1.12% of average net assets annualized or
$0.04 per share).

The Company has a distribution agreement with Prudential Investment Management
Services ('PIMS'), which acts as the distributor of the Company. No distribution
or service fees are paid to PIMS as distributor of the Fund.

PIFM, PIC and PIMS are indirect, wholly owned subsidiaries of The Prudential.

As of March 11, 1999, the Company, along with other affiliated registered
investment companies (the 'Funds'), entered into a syndicated credit agreement
('SCA') with an unaffiliated lender. The maximum commitment under the SCA is $1
billion. The Funds pay a commitment fee at an annual rate of .065 of 1% on the
unused portion of the credit facility, which is accrued and paid quarterly on a
pro rata basis by the Funds. The SCA expires on March 9, 2000. Prior to March
11, 1999, the Funds had a credit agreement with a maximum commitment of
$200,000,000. The commitment fee was .055 of 1% on the unused portion of the
credit facility. The Fund did not borrow any amounts pursuant to either
agreement during the six months ended March 31, 1999. The purpose of the
agreements are to serve as an alternative source of funding for capital share
redemptions.
- ------------------------------------------------------------
Note 3. Other Transactions With Affiliates

Prudential Mutual Fund Services LLC ('PMFS'), a wholly owned subsidiary of PIFM,
serves as the Company's transfer agent. During the six months ended March 31,
1999, the Fund incurred fees of approximately $400 for the services of PMFS.
Transfer agent fees and expenses in the Statement of Operations also include
certain out-of-pocket expenses paid to nonaffiliates.
- ------------------------------------------------------------
Note 4. Portfolio Securities

Purchases and sales of investment securities, other than short-term investments,
for the six months ended March 31, 1999 were $887,459 and $292,539,
respectively.

The cost basis of investments for federal income tax purposes at March 31, 1999
was $25,408,791 and, accordingly, net unrealized depreciation for federal income
tax purposes was $2,333,591 (gross unrealized appreciation--$1,361,291; gross
unrealized depreciation--$3,694,882).

The Fund elected to treat approximately $20,600 of net currency losses and
$376,500 of net capital losses incurred during the 11-month period ended
September 30, 1998 as having occurred in the current fiscal year.

Notes to Financial Statements                   PRUDENTIAL INDEX SERIES FUND
(Unaudited)                                     PRUDENTIAL SMALL-CAP INDEX FUND
- --------------------------------------------------------------------------------
The Prudential Index Series Fund (the 'Company') is registered under the
Investment Company Act of 1940 as an open-end, diversified management investment
company. The Company was established as a Delaware business trust on May 11,
1992 and currently consists of five separate funds (the 'Funds'). Prudential
Small-Cap Index Fund (the 'Fund') commenced investment operations on October 1,
1997 when 1,860,203 shares of beneficial interest of the Fund were sold for
$18,602,031 to The Prudential Insurance Company of America ('The Prudential').
The Fund's investment objective is to provide investment results that correspond
to the price and yield performance of a broad-based index of Small Cap stocks.
The Fund currently uses the Standard & Poor's 600 Small Capitalization Stock
Price Index price for that purpose.
- ------------------------------------------------------------
Note 1. Accounting Policies
The following is a summary of significant accounting policies followed by the
Fund.
Securities Valuation: Securities, including options, warrants, futures contracts
and options thereon, for which the primary market is on a national securities
exchange, commodities exchange or board of trade or Nasdaq are valued at the
last sale price on such exchange or board of trade on the date of valuation or,
if there was no sale on such day, at the mean between the closing bid and asked
prices quoted on such day or at the bid price in the absence of an asked price.
Securities that are actively traded in the over-the-counter market, including
listed securities for which the primary market is believed to be
over-the-counter, are valued by a principal market maker or independent pricing
agent.
U.S. Government securities for which market quotations are available shall be
valued at a price provided by an independent broker/dealer or pricing service.
Securities for which reliable market quotations are not available or for which
the pricing agent or principal market maker does not provide a valuation or
methodology or provides a valuation or methodology that, in the judgment of the
subadvisers does not represent fair value, are valued at fair value as
determined under procedures established by the Trustees.
In connection with transactions in repurchase agreements, it is the Fund's
policy that its custodian or designated subcustodians under triparty repurchase
agreements, as the case may be, take possession of the underlying collateral
securities, the value of which exceeds 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 Net Investment Income: Securities transactions are
recorded on the trade date. Realized gains and losses on sales of securities are
calculated on the identified cost basis. Dividend income is recorded on the
ex-dividend date and interest income is recorded on the accrual basis. Expenses
are recorded on the accrual basis which may require the use of certain estimates
by management.
Financial Futures Contracts: A financial futures contract is an agreement to
purchase (long) or sell (short) an agreed amount of securities or commodities at
a set price for delivery on a future date. Upon entering into a financial
futures contract, the Fund is required to pledge to the broker an amount of cash
and/or other assets equal to a certain percentage of the contract amount. This
amount is known as the 'initial margin.' Subsequent payments, known as
'variation margin,' are made or received by the Fund each day, depending on the
daily fluctuations in the value of the underlying security or commodity. Such
variation margin is recorded for financial statement purposes on a daily basis
as unrealized gain or loss. When the contract expires or is closed, the gain or
loss is realized and is presented in the statement of operations as net realized
gain (loss) on financial futures contracts.
The Fund invests in financial futures contracts in order to hedge existing
portfolio securities, or securities the Fund intends to purchase, against
fluctuations in value. Under a variety of circumstances, the Fund may not
achieve the anticipated benefits of the financial futures contracts and may
realize a loss. The use of futures transactions involves the risk of imperfect
correlation in movements in the price of futures contracts and the underlying
assets.
Dividends and Distributions: Dividends and distributions of the Fund are
declared in cash and automatically reinvested in additional shares of the Fund.
The Fund will declare and distribute its net investment income and net capital
gains, if any, at least annually. Dividends and distributions are recorded on
the ex-dividend date.
Income distributions and capital gain distributions are determined in accordance
with income tax regulations which may differ from generally accepted accounting
principles.

(Unaudited)                                     PRUDENTIAL SMALL-CAP INDEX FUND
- --------------------------------------------------------------------------------
Federal Income Taxes: It is the Fund's policy to meet the requirements of the
Internal Revenue Code applicable to regulated investment companies and to
distribute all of its taxable net investment income and net capital gains, if
any, to its shareholders. Therefore, no federal income tax provision is
required.
Withholding taxes on foreign dividends have been provided for in accordance with
the Fund's understanding of the applicable country's tax rules and rates.
- ------------------------------------------------------------
Note 2. Agreements
The Fund has a management agreement with Prudential Investment Fund Management
LLC ('PIFM' or the 'Manager'). Pursuant to this agreement PIFM has
responsibility for all investment advisory services. PIFM has entered into a
subadvisory agreement with The Prudential Investment Corporation ('PIC'). PIC,
subject to the supervision of PIFM, manages the assets of the Fund in accordance
with its investment objective and policies. PIFM pays for the costs and expenses
attributable to the subadvisory agreement and the salaries and expenses of all
personnel of the Fund except for fees and expenses of unaffiliated Trustees. The
management fee paid PIFM is computed daily and payable monthly at an annual rate
of .30 of 1% of the Fund's average daily net assets.
PIFM has agreed to reimburse the Fund so that total operating expenses do not
exceed .50% of the average net assets of the Fund for the six months ended March
31, 1999. This voluntary waiver may be terminated at any time without notice.
For the six months ended March 31, 1999, PIFM subsidized $102,676 for the
expenses of the Fund (.64% of the average net assets of the Fund/$.03 per
share.)
Prudential Securities Incorporated ('PSI') acted as the distributor of the
Fund's shares through May 31, 1998. Prudential Investment Management Services
('PIMS') became the distributor of the Fund effective June 1998 and is serving
under the same terms and conditions as under the agreement with PSI. Under the
distribution agreement, PSI and PIMS incurred the expenses of distributing the
Fund's shares, none of which is reimbursed or paid for by the Fund.
PIC, PIFM, PIMS and PSI are wholly owned subsidiaries of The Prudential
Insurance Company of America.
As of March 11, 1999, the Fund, along with other affiliated registered
investment companies (the 'Funds'), entered into a syndicated credit agreement
('SCA') with an unaffiliated lender. The maximum commitment under the SCA is $1
billion. The Funds pay a commitment fee at an annual rate of .065 of 1% on the
unused portion of the credit facility, which is accrued and paid quarterly on a
pro rata basis by the Funds. The SCA expires on March 9, 2000. Prior to March
11, 1999, the Funds had a credit agreement with a maximum commitment of
$200,000,000. The commitment fee was .055 of 1% on the unused portion of the
credit facility. The Fund did not borrow any amounts pursuant to either
agreement during the six months ended March 31, 1999. The purpose of the
agreements are to serve as an alternative source of funding for capital share
redemptions.
- ------------------------------------------------------------
Note 3. Other Transactions With Affiliates
Prudential Mutual Fund Services LLC ('PMFS'), a wholly owned subsidiary of PIFM,
serves as the Fund's transfer agent. During the six months ended March 31, 1999,
the Fund incurred fees of approximately $2,300 for the services of PMFS. As of
March 31, 1999, approximately $900 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 nonaffiliates.
- ------------------------------------------------------------
Note 4. Portfolio Securities
Purchases and sales of portfolio securities, excluding short-term investments,
for the six months ended March 31, 1999 aggregated $7,415,121 and $2,437,041,
respectively.
On March 31, 1999, the Fund held the following two futures contracts expiring
June 1999.

Notes to Financial Statements (Unaudited)     PRUDENTIAL BOND MARKET INDEX FUND
- --------------------------------------------------------------------------------
Prudential Index Series Fund, (the 'Company') is registered under the Investment
Company Act of 1940 as an open-end, diversified management investment company.
The Company was established as a Delaware business trust on May 11, 1992 and
currently consists of five separate funds. Prudential Bond Market Index Fund
(the 'Fund') commenced investment operations on October 1, 1997 when 3,000,020
shares of beneficial interest of the Fund were sold for $30,000,200 to the
Prudential Insurance Company of America ('The Prudential').

The Fund's investment objective is to seek to provide investment results that
correspond to the total return performance of a broad-based index of
fixed-income securities, currently the Lehman Brothers Aggregate Bond Index.
- ------------------------------------------------------------
Note 1. Accounting Policies

The following is a summary of significant accounting policies followed by the
Company and the Fund in the preparation of its financial statements.

Securities Valuation: Securities for which the primary market is on an exchange
are valued at the last sale price on such exchange on the day of valuation or,
if there were no sales on such day, at the mean between the last bid price and
asked prices on such day or at the bid price on such day in the absence of an
asked price. Securities that are actively traded in the over-the-counter market,
including listed securities for which the primary market is believed to be
over-the-counter, are valued by an independent pricing agent or a principal
market maker. U.S. Government securities for which market quotations are
available are valued at a price provided by an independent broker/dealer or
pricing service.

Options on securities that are listed on an exchange are valued at the last
sales price at the close of trading on such exchange or, if there were no sales
on the applicable option exchange, on such day at the average of the quoted bid
and asked prices as of the close of such exchange. Futures contracts and options
thereon traded on a commodities exchange or board of trade are valued at the
last sale price at the close of trading on such exchange or board of trade or,
if there was no sale on the applicable commodities exchange or board of trade on
such day, at the average of the quoted bid and asked prices as of the close of
such exchange or board of trade. Securities for which reliable market quotations
are not available or for which the pricing agent or principal market maker does
not provide a valuation or methodology that, in the judgement of the subadviser,
represent fair value, are valued at fair value as determined by procedures
established by the Company's Trustees.

Short-term securities which mature in more than 60 days are valued at current
market quotations. Short-term securities which mature in 60 days or less are
valued at amortized cost.

In connection with transactions in repurchase agreements with U.S. financial
institutions, it is the Company's policy that its custodian or designated
subcustodians, under triparty repurchase agreements as the case may be, take
possession of the underlying collateral securities, the value of which exceeds
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.

Dollar Rolls: The Fund enters into mortgage dollar rolls in which the Fund sells
mortgage securities for delivery in the current month, realizing a gain or loss
and simultaneously contracts to repurchase somewhat similar (same type, coupon
and maturity) securities on a specified future date. During the roll period, the
Fund forgoes principal and interest paid on the securities. The Fund is
compensated by the interest earned on the cash proceeds of the initial sale and
by the lower repurchase price at the future date. The difference between the
sales proceeds and the lower repurchase price is recorded as interest income.
The Fund maintains a segregated account, the dollar value of which is at least
equal to its obligations, in respect of dollar rolls.

Securities Transactions and Net Investment Income: Securities transactions are
recorded on the trade date. Realized gains or losses from investment
transactions are calculated on the identified cost basis. Interest income is
recorded on the accrual basis. The Fund accretes discounts and amortizes
premiums on portfolio securities as adjustments to interest income. Expenses are
recorded on the accrual basis which may require the use of certain estimates by
management.

Dividends and Distributions: The Fund expects to pay dividends of net investment
income and distributions of net realized capital gains, if any, at least
annually. Dividends and distributions are recorded on the ex-dividend date.

Income distributions and capital gain distributions are determined in accordance
with income tax regulations which may differ from generally accepted accounting
principles.

Taxes: For federal income tax purposes, each fund in the Company is treated as a
separate taxpaying entity. It is the Fund'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 investment income to its
shareholders. Therefore, no federal income tax provision is required.
- ------------------------------------------------------------
Note 2. Agreements

The Company has a management agreement with Prudential Investments Fund
Management LLC ('PIFM'). Pursuant to this agreement, PIFM has responsibility for
all investment advisory services and supervises the subadviser's performance of
such services. PIFM has entered into a subadvisory agreement with The Prudential
Investment Corporation ('PIC'); PIC furnishes investment advisory services in
connection with the management of the Company. PIFM pays for the cost of the
subadviser's services, the compensation of officers of the Company, occupancy
and certain clerical and bookkeeping costs of the Company. The Company bears all
other costs and expenses.

The management fee paid PIFM is computed daily and payable monthly, at an annual
rate of .25 of 1% of the Fund's average daily net assets.

The Company has a distribution agreement with Prudential Investment Management
Services LLC ('PIMS') which acts as the distributor of the Fund. No distribution
or service fees are paid to PIMS as distributor of the Fund.

PIFM, PIC and PIMS are indirect wholly owned subsidiaries of The Prudential
Insurance Company of America.

PIFM has agreed to subsidize the operating expenses of the Fund, so that total
Fund operating expenses do not exceed .40% on an annualized basis of the Fund's
average daily net assets. This voluntary waiver may be terminated at any time
without notice. For the six months ended March 31, 1999, PIFM subsidized $67,098
of the expenses of the Fund (0.33% of the average daily net assets annualized or
$0.016 per share).

As of March 11, 1999, the Company, along with other affiliated registered
investment companies (the 'Funds'), entered into a syndicated credit agreement
('SCA') with an unaffiliated lender. The maximum commitment under the SCA is $1
billion. The Funds pay a commitment fee at an annual rate of .065 of 1% on the
unused portion of the credit facility, which is accrued and paid quarterly on a
pro rata basis by the Funds. The SCA expires on March 9, 2000. Prior to March
11, 1999, the Funds had a credit agreement with a maximum commitment of
$200,000,000. The commitment fee was .055 of 1% on the unused portion of the
credit facility. The Fund did not borrow any amounts pursuant to either
agreement during the six months ended March 31, 1999. The purpose of the
agreements are to serve as an alternative source of funding for capital share
redemptions.
- ------------------------------------------------------------
Note 3. Other Transactions With Affiliates

Prudential Mutual Fund Services LLC ('PMFS'), a wholly owned subsidiary of PIFM,
serves as the Company's transfer agent. During the six months ended March 31,
1999, the Fund incurred fees of approximately $2,900 for the services of PMFS.
As of March 31, 1999, approximately $600 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 nonaffiliates.
- ------------------------------------------------------------
Note 4. Portfolio Securities

Purchases and sales of investment securities, other than short-term investments,
for the six months ended March 31, 1999, were $30,390,894 and $27,466,943,
respectively, which includes purchases and sales of U.S. government obligations
of $27,150,497 and $26,163,348, respectively.

The federal income tax basis of the Fund's investments at March 31, 1999 was
$53,696,672 and, accordingly, net unrealized appreciation for federal income tax
purposes was $214,675 (gross unrealized appreciation-$356,026; gross unrealized
depreciation-$141,351).

The average balance of dollar rolls outstanding during the six months ended
March 31, 1999 was approximately $10,027,648. The value of dollar rolls
outstanding at March 31, 1999 was $11,166,080, which was 17% of total assets.
- ------------------------------------------------------------
Note 5. Joint Repurchase Agreement Account

The Company, along with other affiliated registered investment companies,
transfers uninvested cash balances into a single joint account, the daily
aggregate balance of which is invested in one or more repurchase agreements
collateralized by U.S. Treasury or federal agency obligations. As of March 31,
1999, the Fund had a 2.08% undivided interest in the repurchase agreements in
the joint account. This undivided interest represented $11,516,000 in principal
amount. As of such date, the repurchase agreements in the joint account and the
value of the collateral therefore were as follows:

                             DESCRIPTION OF RATINGS

S&P RATINGS CORPORATE BOND RATINGS:

      AAA-Bonds rated AAA have the highest rating assigned by S&P Ratings to a
debt obligation. Capacity to pay interest and repay principal is extremely
strong.

      AA-Bonds rated AA have a very strong capacity to pay interest and repay
principal and differ from the highest rated issues only in small degree.

      A-Bonds rated A have a strong capacity to pay interest and repay principal
although they are somewhat more sus ceptibleto the adverse effects of changes in
circumstances and economic conditions than bonds in higher rated categories.

      BBB-Bonds rated BBB are regarded as having an adequate capacity to pay
interest and repay principal. Whereas they normally exhibit 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
bonds in this category than for bonds in higher rated categories.

      BB, B, CCC, CC, C-Bonds rated BB, B, CCC, CC, or C are regarded, on
balance, as predominantly speculative with respect to capacity to pay interest
and repay principal in accordance with the terms of the obligation. BB
represents the lowest degree of speculation and C the highest degree of
speculation. While such bonds will likely have some quality and protective
characteristics, these are outweighed by large uncertainties or major risk
exposures to adverse conditions.

MOODY'S CORPORATE BOND RATINGS:

      AAA-Bonds rated Aaa are judged to be the best quality. They carry the
smallest degree of investment risk and are generally referred to as "gilt edge."
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 these issues.

      AA-Bonds 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 the best bonds because margins of protection
may not be as large as in Aaa securities or fluctuation of protective elements
may be a greater amplitude or there may be other elements present which make the
long-term risks appear somewhat larger than in Aaa securities.

      A-Bonds 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 sometime in the future.

      BAA-Bonds 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 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 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.

      CAA-Bonds 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.


                                      A-1
<PAGE>

      CA-Bonds rated Ca represent obligations which are speculative in a high
degree. Such issues are often in default or have other market shortcomings.

      C-Bonds 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.

      Moody's applies the numerical modifiers 1, 2 and 3 in the Aa and A rating
categories. The modifier 1 indicates that the security 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 issue ranks in the lower end of its
generic rating category.

DUFF & PHELPS BOND RATINGS:

      AAA-Bonds rated AAA by Duff & Phelps are considered to be of the highest
credit quality. The risk factors are negligible, being only slightly more than
for risk-free U.S. Treasury debt.

      AA+, AA, AA-Bonds rated AA+, AA or AA- are considered to be of high credit
quality. Protection factors are strong. Risk is modest but may vary slightly
from time to time because of economic conditions.

      A+, A, A-Bonds rated A+, A or A- have protection factors which are average
but adequate; however, risk factors are more variable and greater in periods of
economic stress.

      BBB+, BBB, BBB-Bonds rated BBB+, BBB or BBB- have below average protection
factors but are still considered sufficient for prudent investment. These bonds
demonstrate considerable variability in risk during economic cycles.

      BB+, BB, BB-Bonds rated BB+, BB or BB- are below investment grade but are
still deemed likely to meet obligations when due. Present or prospective
financial protection factors fluctuate according to industry conditions or
company fortunes. Overall quality may move up or down frequently within this
category.

      B+, B, B-Bonds rated B+, B or B- are below investment grade and possess
the risk that obligations will not be met when due. Financial protection factors
will fluctuate widely according to economic cycles, industry conditions and/or
company fortunes. Potential exists for frequent changes in the rating within
this category or into a higher or lower rating grade.

      CCC-Bonds rated CCC are well below investment grade securities.
Considerable uncertainty exists as to timely payment of principal, interest or
preferred dividends. Protection factors are narrow and risk can be substantial
with unfavorable economic/industry conditions, and/or with unfavorable company
developments.

      DD-Bonds rated DD are defaulted debt obligations. The issuer failed to
meet scheduled principal and/or interest payments.

S&P COMMERCIAL PAPER RATINGS:

      Commercial paper rate A-1 by S&P Ratings indicates that the degree of
safety regarding timely payment is either overwhelming or very strong. Those
issues determined to possess overwhelming safety characteristics are denoted
A-1+. Capacity for timely payment on commercial paper rated A-2 is strong, but
the relative degree of safety is not as high as for issues designated A-1.

MOODY'S COMMERCIAL PAPER RATINGS:

      The rating Prime-1 is the highest commercial paper rating assigned by
Moody's. Issuers rated prime-1 (or related supporting institutions) are
considered to have a superior capacity for repayment of short-term promissory
obligations. Issuers rated Prime-2 (or related supporting institutions) are
considered to have a strong capacity for repayment of short-term promissory
obligations. This will normally be evidenced by many of the characteristics of
issuers rated Prime-1 but to a lesser degree. Earnings trends and coverage
ratios, while sound, will be more subject to variation. Capitalization
characteristics, while still appropriate, may be more affected by external
conditions. Ample alternative liquidity is maintained.


                                      A-2
<PAGE>

DUFF & PHELPS COMMERCIAL PAPER RATINGS:

      Duff & Phelps commercial paper ratings are divided into three categories,
ranging from "1" for the highest quality obligations to "3" for the lowest. No
ratings are issued for companies whose paper is not deemed investment grade.
Issues assigned the Duff 1 rating are considered top grade. This category is
further divided into three gradations as follows: Duff 1 plus--highest certainty
of timely payment, short-term liquidity, including internal operating factors
and/or ready access to alternative sources of funds, is clearly outstanding and
safety is just below risk-free U.S. Treasury short-term obligations; Duff
1--very high certainty or timely payment liquidity factor are excellent and
supported by strong fundamental protection factors, risk factors are minor; Duff
1 minus-high certainty of timely payment, liquidity factors are strong and
supported by good fundamental protection factors, risk factors are very small.
Issues rated Duff 2 represent a good certainty of timely payment; liquidity
factors and company fundamentals are sound; although ongoing internal funds
needs may enlarge total financing requirements, access to capital markets is
good; risk factors are small. Duff 3 represents a satisfactory grade;
satisfactory liquidity and other protection factors qualify issue as to
investment grade; risk factors are larger and subject to more variation;
nevertheless timely payment is expected.

                   APPENDIX I--GENERAL INVESTMENT INFORMATION

      The following terms are used in mutual fund investing.

ASSET ALLOCATION

      Asset allocation is a technique for reducing risk, providing balance.
Asset allocation among different types of securities within an overall
investment portfolio helps to reduce risk and to potentially provide stable
returns, while enabling investors to work toward their financial goal(s). Asset
allocation is also a strategy to gain exposure to better performing asset
classes while maintaining investment in other asset classes.

DIVERSIFICATION

      Diversification is a time-honored technique for reducing risk, providing
"balance" to an overall portfolio and potentially achieving more stable returns.
Owning a portfolio of securities mitigates the individual risks (and returns) of
any one security. Additionally, diversification among types of securities
reduces the risks (and general returns) of any one type of security.

DURATION

      Debt securities have varying levels of sensitivity to interest rates. As
interest rates fluctuate, the value of a bond (or a bond portfolio) will
increase or decrease. Longer term bonds are generally more sensitive to changes
in interest rates. When interest rates fall, bond prices generally rise.
Conversely, when interest rates rise, bond prices generally fall.


      Duration is an approximation of the price sensitivity of a bond (or a bond
portfolio) to interest rate changes. It measures the weighted average maturity
of a bond's (or a bond portfolio's) cash flows, that is, principal and interest
rate payments. Duration is expressed as a measure of time in years--the longer
the duration of a bond (or a bond portfolio), the greater the impact of interest
rate changes on the bond's (or the bond portfolio's) price. Duration differs
from effective maturity in that duration takes into account call provisions,
coupon rates and other factors. Duration measures interest rate risk only and
not other risks, such as credit risk and, in the case of non-U.S. dollar
denominated securities, currency risk. Effective maturity measures the final
maturity dates of a bond (or a bond portfolio).


MARKET TIMING

      Market timing--buying securities when prices are low and selling them when
prices are relatively higher--may not work for many investors because it is
impossible to predict with certainty how the price of a security will fluctuate.
However, owning a security for a long period of time may help investors offset
short-term price volatility and realize positive returns.

POWER OF COMPOUNDING

      Over time, the compounding of returns can significantly impact investment
returns. Compounding is the effect of continuous investment on long-term
investment results, by which the proceeds of capital appreciation (and income
distributions, if elected) are reinvested to contribute to the overall growth of
assets. The long-term investment results of compounding may be greater than that
of an equivalent initial investment in which the proceeds of capital
appreciation and income distributions are taken in cash.

STANDARD DEVIATION

      Standard deviation is an absolute (non-relative) measure of volatility
which, for a mutual fund, depicts how widely the returns varied over a certain
period of time. When a fund has a high standard deviation, its range of
performance has been very wide, implying greater volatility potential. Standard
deviation is only one of several measures of a fund's volatility.

Generally, stock returns are due to capital appreciation and reinvesting any
gains. Bond returns are due mainly to reinvesting interest. Also, stock prices
are usually more volatile than bond prices over the long-term. Small stock
returns for 1926-1980 are those of stocks comprising the 5th quintile of the New
York Stock Exchange. Thereafter, returns are those of the Dimensional Fund
Advisors (DFA) Small Company Fund. Common stock returns are based on the S&P
Composite Index, a market-weighted, unmanaged index of 500 stocks (currently) in
a variety of industries. It is often used as a broad measure of stock market
performance.

Long-term government bond returns are measured using a constant one-bond
portfolio with a maturity of roughly 20 years. Treasury bill returns are for a
one-month bill. Treasuries are guaranteed by the government as to the timely
payment of principal and interest; equities are not. Inflation is measured by
the consumer price index (CPI).

      Set forth below is historical performance data relating to various sectors
of the fixed-income securities markets. The chart shows the historical total
returns of U.S. Treasury bonds, U.S. mortgage securities, U.S. corporate bonds,
U.S. high yield bonds and world government bonds on an annual basis from 1988
through 1998. The total returns of the indices include accrued interest, plus
the price changes (gains or losses) of the underlying securities during the
period mentioned. The data is provided to illustrate the varying historical
total returns and investors should not consider this performance data as an
indication of the future performance of the Funds or of any sector in which the
Funds invest.



      All information relies on data obtained from statistical services, reports
and other services believed by the Manager to be reliable. Such information has
not been verified. The figures do not reflect the operating expenses and fees of
a mutual fund. See "Risk/Return Summary--Fees and Expenses" in each Prospectus.
The net effect of the deduction of the operating expenses of a mutual fund on
these historical total returns, including the compounded effect over time, could
be substantial.

INFORMATION ABOUT THE PRUDENTIAL MUTUAL FUNDS


      As of        31, 1999, Prudential Investments Fund Management was the 20th
largest mutual fund company in the country, with over 2.5 million shareholders
invested in more than 50 mutual fund portfolios and variable annuities with more
than 3.7 million shareholder accounts.


      The Prudential Mutual Funds have over 30 portfolio managers who manage
over $55 billion in mutual fund and variable annuity assets. Some of
Prudential's portfolio managers have over 20 years of experience managing
investment portfolios.

      From time to time, there may be media coverage of portfolio managers and
other investment professionals associated with the Manager and the Subadviser in
national and regional publications, on television and in other media.
Additionally, individual mutual fund portfolios are frequently cited in surveys
conducted by national and regional publications and media organizations such as
THE WALL STREET JOURNAL, THE NEW YORK TIMES, BARRON'S and USA TODAY.


      EQUITY FUNDS. Prudential Equity Fund is managed with a "value" investment
style by PIC. In 1995, Prudential Securities introduced Prudential Jennison
Growth Fund, a growth-style equity fund managed by Jennison Associates LLC, a
premier institutional equity manager and a subsidiary of Prudential.



      HIGH YIELD FUNDS. Investing in high yield bonds is a complex and research
intensive pursuit. A separate team of high yield bond analysts monitor
approximately 200 issues held in the Prudential High Yield Fund (currently the
largest fund of its kind in the country) along with 100 or so other high yield
bonds, which may be considered for purchase(4). Non-investment grade bonds, also
known as junk bonds or high yield bonds, are subject to a greater risk of loss
of principal and interest including default risk than higher-rated bonds.
Prudential high yield portfolio managers and analysts meet face-to-face with
almost every bond issuer in the High Yield Fund's portfolio annually, and have
additional telephone contact throughout the year.



      Prudential's portfolio managers are supported by a large and sophisticated
research organization. Investment grade bond analysts monitor the financial
viability of different bond issuers in the investment grade corporate and
municipal bond markets--from IBM to small municipalities, such as Rockaway
Township, New Jersey. These analysts consider among other things sinking fund
provisions and interest coverage ratios.


      Prudential's portfolio managers and analysts receive research services
from almost 200 brokers and market service vendors. They also receive nearly 100
trade publications and newspapers--from PULP AND PAPER FORECASTER to WOMEN'S
WEAR DAILY--to keep them informed of the industries they follow.

      Prudential Mutual Funds' traders scan over 100 computer monitors to
collect detailed information on which to trade. From natural gas prices in the
Rocky Mountains to the results of local municipal elections, a Prudential
portfolio manager or trader is able to monitor it if it's important to a
Prudential Mutual Fund.


      Prudential Mutual Funds trades billions in U.S. and foreign government
securities a year. PIC seeks information from government policy makers.
Prudential's portfolio managers have met with several senior U.S. and foreign
government officials, on issues ranging from economic conditions in foreign
countries to the viability of index-linked securities in the United States.

ITEM 24. PERSONS CONTROLLED BY OR UNDER COMMON CONTROL WITH THE FUND.


      None.


ITEM 25. INDEMNIFICATION.



      As permitted by Section 17(h) and (i) of the Investment Company Act of
1940, as amended (the 1940 Act), and pursuant to Del. Code Ann. title 12 sec.
3817, a Delaware business trust may provide in its governing instrument for the
indemnification of its officers and trustees from and against any and all claims
and demands whatsoever. Article VII, Section 2 of the Agreement and Declaration
of Trust states that (i) the Registrant shall indemnify any present trustee or
officer to the fullest extent permitted by law against liability, and all
expenses reasonably incurred by him or her in connection with any claim, action,
suit or proceeding in which he or she is involved by virtue of his or her
service as a trustee, officer or both, and against any amount incurred in
settlement thereof and (ii) all persons extending credit to, contracting with or
having any claim against the Registrant shall look only to the assets of the
appropriate Series (or if no Series has yet been established, only to the assets
of the Registrant). Indemnification will not be provided to a person adjudged by
a court or other adjudicatory body to be liable to the Registrant or its
shareholders by reason of willful misfeasance, bad faith, gross negligence or
reckless disregard of his or her duties (collectively "disabling conduct"). In
the event of a settlement, no indemnification may be provided unless there has
been a determination, as specified in the Declaration of Trust, that the officer
or trustee did not engage in disabling conduct. As permitted by Section 17(i) of
the 1940 Act, pursuant to Section 8 of the Distribution Agreement (Exhibit
(e)(1) to the Registration Statement), the Distributor of the Registrant may be
indemnified against liabilities which it may incur, except liabilities arising
from bad faith, gross negligence, willful misfeasance or reckless disregard of
duties.


      Insofar as indemnification for liabilities arising under the Securities
Act of 1933, as amended (Securities Act) may be permitted to trustees, officers
and controlling persons of the Registrant pursuant to the foregoing provisions
or otherwise, the Registrant has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public policy
as expressed in the 1940 Act and is, therefore,


                                      C-2
<PAGE>

unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by the Registrant of expenses incurred or
paid by a trustee, officer, or controlling person of the Registrant in
connection with the successful defense of any action, suit or proceeding) is
asserted against the Registrant by such trustee, officer or controlling person
in connection with the shares being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the 1940 Act and
will be governed by the final adjudication of such issue.

      The Registrant intends to purchase an insurance policy insuring its
officers and trustees against liabilities, and certain costs of defending claims
against such officers and trustees, to the extent such officers and trustees are
not found to have committed conduct constituting willful misfeasance, bad faith,
gross negligence or reckless disregard in the performance of their duties. The
insurance policy also insures the Registrant against the cost of indemnification
payments to officers and trustees under certain circumstances.


      Section 9 of the Management Agreements (Exhibits (d)(1) and (d)(3) to the
Registration Statement) and Section 4 of the Subadvisory Agreements (Exhibits
(d)(2) and (d)(4) to the Registration Statement) limit the liability of
Prudential Investments Fund Management LLC (PIFM) and The Prudential Investment
Corporation (PIC), respectively, to liabilities arising from willful
misfeasance, bad faith or gross negligence in the performance of their
respective duties or from reckless disregard by them of their respective
obligations and duties under the agreements.


      The Registrant hereby undertakes that it will apply the indemnification
provisions of its By-Laws, and the Distribution Agreement in a manner consistent
with Release No. 11330 of the Securities and Exchange Commission under the 1940
Act so long as the interpretation of Section 17(h) and 17(i) of such Act remain
in effect and are consistently applied.

               Re:    Prudential Index Series Fund
                      ----------------------------


Ladies and Gentlemen:

               We acted as special Delaware counsel to Prudential Index Series
Fund, a Delaware business trust (the "Trust"), in connection with the formation
of the Trust and related matters. In such capacity, we rendered an opinion
concerning the Trust dated October 30, 1992, a copy of which is attached hereto
(the "Prior Opinion"). Capitalized terms used herein and not otherwise herein
defined are used as defined in the Prior Opinion.

               In rendering this further opinion, we have examined the documents
referenced in our Prior Opinion and, in addition, copies of: (i) a Second
Amendment to Agreement and Declaration of Trust of the Trust dated as of October
28, 1996 (the "Second Amendment"); (ii) a Third Amendment to Agreement and
Declaration of Trust dated as of October 15, 1997 (the "Third Amendment"); (iii)
a Second Amendment to the Certificate as filed in the Recording Office on
October 29, 1996; (iv) a Third Amendment to the Certificate as filed in the
Recording Office on January 14, 1998; (v) certain minutes of meetings of the
Board of Trustees of the Trust dated February 19, 1997, August 26, 1997 and May
26, 1999; (vii) Post-Effective Amendments Nos. 1-12 to the Registration
Statement of the Trust on Form N1-A, as filed with the Securities and Exchange
Commission (the "Post-Effective Amendments"); and (viii) a certification of good
standing of the Trust obtained from the Recording Office as of a recent date.
The opinions hereinafter expressed are based upon the same assumptions,
effective as of the date of the Prior Opinion and the date hereof, as set forth
in the Prior Opinion, including as applicable to the new documents herein
referenced. For purposes of this supplemental opinion, (A) references to the
Governing Instrument in the Prior Opinion shall be deemed references to the
Governing

Instrument as amended by the Second Amendment and the Third Amendment, (B)
references to the Registration Statement of the Trust in the Prior Opinion shall
be deemed references to the Registration Statement as amended by the
Post-Effective Amendments and (C) references in the Prior Opinion to Applicable
Shares shall be deemed references to Shares of the currently existing Series of
the Trust (and classes thereof).

               Based on and subject to the foregoing, and limited in all
respects to matters of Delaware law, we hereby reconfirm to you as of the date
hereof the opinions set forth in the Prior Opinion.

               We consent to the filing of this supplemental opinion as an
Exhibit to the Registration Statement. In giving this consent, we do not thereby
admit that we come within the category of persons whose consent is required
under Section 7 of the Securities Act of 1933, as amended, or the rules and
regulations of the Securities and Exchange Commission thereunder. This
supplemental opinion is intended solely for the benefit of the addressee hereof
and, except as provided in the foregoing sentence, may not be furnished or
quoted to, or relied upon, by any other person or entity for any purpose without
our prior written consent. This opinion speaks only as of the date hereof and is
based on our understandings and assumptions as to present facts and our review
of the above-referenced documents and certificates and the application of
Delaware law as the same exists on the date hereof, and we undertake no
obligation to update or supplement this supplemental opinion after the date
hereof for the benefit of any person or entity with respect to any facts or
circumstances that may hereafter come to our attention or any changes in facts
or law that may hereafter occur or take effect.

                                Very truly yours,

Securities and Exchange Commission on May 21, 1992; and a certificate of good
standing of the Trust obtained as of a recent date from the Recording Office. In
such examinations, we have assumed the genuineness of all signatures, the
conformity to original documents of all documents submitted to us as copies or
drafts of documents to be executed and the legal capacity of natural persons to
complete the execution of documents. We have further assumed for the purpose of
this opinion: (i) the due authorization, execution and delivery by, or on behalf
of, each of the parties thereto of the above-referenced instruments,
certificates and other documents (provided that we do not assume due
authorization of any of the foregoing on behalf of the Trust), and of all
documents contemplated by the Governing Instrument, By-Laws, applicable
Resolutions of the Sole Trustee or Trustees and the Registration Statement
(including the Prospectus and Statement of Additional Information forming a part
thereof) (collectively, the "Operative Documents") to be executed by investors
acquiring Applicable Shares (the "Shareholders" and each, individually, a
"Shareholder"); (ii) the payment of consideration for Applicable Shares, and the
application of such consideration, as provided in the Governing Instrument, and
compliance with the other terms, conditions and restrictions set forth in the
Operative Documents in connection with the issuance of Applicable Shares; (iii)
that appropriate notation of the names and addresses of, the number of

of the Certificate that would cause a termination or reorganization of the Trust
under Section 2 or 3 of Article VIII of the Governing Instrument; (v) that the
activities of the Trust have been and will be conducted in accordance with the
terms of the Governing Instrument and the Delaware Business Trust Act, 12 Del.
C. ss.ss. 3801 et seq. (the "Delaware Act"); and (vi) that each of the documents
examined by us is in full force and effect and has not been modified,
supplemented or otherwise amended, except as herein referenced. No opinion is
expressed herein with respect to the requirements of, or compliance with,
federal or state securities or blue sky laws. Further, we have not participated
in the preparation of the Registration Statement or any other offering
documentation relating to the Trust, the Applicable Shares or the related
Series, and we assume no responsibility for their contents. As to any facts
material to our opinion, other than those assumed, we have relied without
independent investigation on the above-referenced documents and on the accuracy,
as of the date hereof, of the matters therein contained.

               Based on and subject to the foregoing, and limited in all
respects to matters of Delaware law, it is our opinion that:

               1. The Trust is a duly organized and validly existing business
trust in good standing under the laws of the State of Delaware.

               2. The issuance of the Applicable Shares has been duly authorized
on behalf of the Trust and, when issued to Shareholders in accordance with the
terms, conditions, requirements and procedures set forth in the Operative
Documents, the Applicable Shares will constitute legally issued, fully paid and
non-assessable Shares of beneficial interest in the Trust.

               3. Under the Delaware Act and the terms of the Governing
Instrument, each Shareholder of the Trust, in such capacity, will be entitled to
the same limitation of personal liability as that extended to stockholders of
private corporations for profit organized under the General Corporation Law of
the State of Delaware; provided, however, that we express no opinion

with respect to the liability of any Shareholder who is, was or may become a
named Trustee of the Trust. Neither the existence nor exercise of the voting
rights granted to Shareholders under the Governing Instrument will, of itself,
cause a Shareholder to be deemed a trustee of the Trust under the Delaware Act.
Notwithstanding the foregoing or the opinion expressed in paragraph 2 above, we
note that, pursuant to Section 5 of Article IV of the Governing Instrument, the
Trustees have the power to cause Shareholders, or Shareholders of a particular
Series, to have the obligation to pay certain custodian, transfer, servicing or
similar agent charges by setting off the same against declared but unpaid
dividends or by reducing Share ownership.

               We consent to the filing of this opinion as an Exhibit to the
Registration Statement. In giving this consent, we do not thereby admit that we
come within the category of persons whose consent is required under Section 7 of
the Securities Act of 1933, as amended, or the rules and regulations of the
Securities and Exchange Commission thereunder.

               We understand that the firm of Arnold & Porter may rely as to
matters of Delaware law on the opinions set forth above in connection with the
rendering of its opinion to you dated on or about the date hereof concerning the
issuance of Applicable Shares, and we hereby consent to such reliance. Except as
provided above, the opinions set forth above are expressed solely for the
benefit of the addressee hereof and may not be furnished or quoted to, or relied
upon, by any other person or entity for any purpose without our prior written
consent.

                          PRUDENTIAL INDEX SERIES FUND

                           Prudential Stock Index Fund

                          Distribution and Service Plan

                                (Class A Shares)

                                  Introduction

     The Distribution and Service Plan (the Plan) set forth below which is
designed to conform to the requirements of Rule 12b-1 under the Investment
Company Act of 1940 (the Investment Company Act) and Rule 2830 of the Conduct
Rules of the National Association of Securities Dealers, Inc. (NASD) has been
adopted by Prudential Stock Index Fund (the Fund), a series of Prudential Index
Series Fund (the Company) and by Prudential Investment Management Services LLC,
the Fund's distributor (the Distributor).

     The Company has entered into a distribution agreement pursuant to which the
Fund will employ the Distributor to distribute Class A shares issued by the Fund
(Class A shares). Under the Plan, the Fund intends to pay to the Distributor, as
compensation for its services, a distribution and service fee with respect to
Class A shares.

     A majority of the Board of Trustees of the Company, including a majority of
those Trustees who are not "interested persons" of the Company (as defined in
the Investment Company Act) and who have no direct or indirect financial
interest in the operation of this Plan or any agreements related to it (the Rule
12b-1 Trustees), have determined by votes cast in person at a meeting called for
the purpose of voting on this Plan that there is a reasonable likelihood that
adoption and continuation of this Plan will benefit the Fund and its
shareholders. Expenditures under this Plan by the Fund


                                       1
<PAGE>


for Distribution Activities (defined below) are primarily intended to result in
the sale of Class A shares of the Fund within the meaning of paragraph (a)(2) of
Rule 12b-1 promulgated under the Investment Company Act.

     The purpose of the Plan is to create incentives to the Distributor and/or
other qualified broker-dealers and their account executives to provide
distribution assistance to their customers who are investors in the Fund, to
defray the costs and expenses associated with the preparation, printing and
distribution of prospectuses and sales literature and other promotional and
distribution activities and to provide for the servicing and maintenance of
shareholder accounts.

                                    The Plan

     The material aspects of the Plan are as follows:

1.   Distribution Activities

     The Fund shall engage the Distributor to distribute Class A shares of the
Fund and to service shareholder accounts using all of the facilities of the
Distributor's distribution network, including sales personnel and branch office
and central support systems, and also using such other qualified broker-dealers
and financial institutions as the Distributor may select, including Prudential
Securities Incorporated (Prudential Securities) and Pruco Securities Corporation
(Prusec). Services provided and activities undertaken to distribute Class A
shares of the Fund are referred to herein as "Distribution Activities."

2.   Payment of Service Fee

     The Fund shall pay to the Distributor as compensation for providing
personal service and/or maintaining shareholder accounts a service fee of .25 of
1% per annum


                                       2
<PAGE>


of the average daily net assets of the Class A shares (service fee). The Fund
shall calculate and accrue daily amounts payable by the Class A shares of the
Fund hereunder and shall pay such amounts monthly or at such other intervals as
the Board of Trustees may determine.

3.   Payment for Distribution Activities

     The Fund shall pay to the Distributor as compensation for its services a
distribution fee, together with the service fee (described in Section 2 hereof),
of .30 of 1% per annum of the average daily net assets of the Class A shares of
the Fund for the performance of Distribution Activities. The Fund shall
calculate and accrue daily amounts payable by the Class A shares of the Fund
hereunder and shall pay such amounts monthly or at such other intervals as the
Board of Trustees may determine. Amounts payable under the Plan shall be subject
to the limitations of Rule 2830 of the NASD Conduct Rules.

     Amounts paid to the Distributor by the Class A shares of the Fund will not
be used to pay the distribution expenses incurred with respect to any other
class of shares of the Fund except that distribution expenses attributable to
the Fund as a whole will be allocated to the Class A shares according to the
ratio of the sales of Class A shares to the total sales of the Fund's shares
over the Fund's fiscal year or such other allocation method approved by the
Board of Trustees. The allocation of distribution expenses among classes will be
subject to the review of the Board of Trustees.

     The Distributor shall spend such amounts as it deems appropriate on
Distribution Activities which include, among others:


                                       3
<PAGE>


     (a)  sales commissions and trailer commissions paid to, or on account of,
          account executives of the Distributor;

     (b)  indirect and overhead costs of the Distributor associated with
          Distribution Activities, including central office and branch expenses;

     (c)  amounts paid to Prudential Securities or Prusec for performing
          services under a selected dealer agreement between Prudential
          Securities or Prusec and the Distributor for sale of Class A shares of

          on account of, agents and indirect and overhead costs associated with
          Distribution Activities;

     (d)  advertising for the Fund in various forms through any available
          medium, including the cost of printing and mailing Fund prospectuses,
          statements of additional information and periodic financial reports
          and sales literature to persons other than current shareholders of the
          Fund; and

     (e)  sales commissions (including trailer commissions) paid to, or on
          account of, broker-dealers and financial institutions (other than
          Prudential Securities or Prusec) which have entered into selected
          dealer agreements with the Distributor with respect to Class A shares
          of the Fund.

4.   Quarterly Reports; Additional Information

     An appropriate officer of the Company will provide to the Board of Trustees
of the Company for review, at least quarterly, a written report specifying in
reasonable detail the amounts expended for Distribution Activities (including
payment of the service fee) and the purposes for which such expenditures were
made in compliance with the requirements of Rule 12b-1. The Distributor will
provide to the Board of Trustees of the Company such additional information as
the Board shall from time to time reasonably request, including information
about Distribution Activities undertaken or to be undertaken by the Distributor.


                                       4
<PAGE>


     The Distributor will inform the Board of Trustees of the Company of the
commissions and account servicing fees to be paid by the Distributor to account
executives of the Distributor and to broker-dealers and financial institutions
which have selected dealer agreements with the Distributor.

5.   Effectiveness; Continuation

     If approved by a vote of a majority of the outstanding voting securities of
the Class A shares of the Fund, the Plan shall, unless earlier terminated in
accordance with its terms, continue in full force and effect thereafter for so
long as such continuance is specifically approved at least annually by a
majority of the Board of Trustees of the Company and a majority of the Rule
12b-1 Trustees by votes cast in person at a meeting called for the purpose of
voting on the continuation of the Plan.

6.   Termination

     This Plan may be terminated at any time, without the payment of any
penalty, by a majority of the Rule 12b-1 Trustees, or by vote of a majority of
the outstanding voting securities (as defined in the Investment Company Act) of
the Class A shares of the Fund, or by the Distributor, on sixty (60) days'
written notice to the other party. This Plan shall automatically terminate in
the event of its assignment.

7.   Amendments

     The Plan may not be amended to change the combined service and distribution
fees to be paid as provided for in Sections 2 and 3 hereof so as to increase
materially the amounts payable under this Plan unless such amendment shall be
approved by the vote of a majority of the outstanding voting securities (as
defined in the Investment Company Act) of the Class A shares of the Fund. All
material amendments of the Plan


                                       5
<PAGE>


shall be approved by a majority of the Board of Trustees of the Company and a
majority of the Rule 12b-1 Trustees by votes cast in person at a meeting called

     While the Plan is in effect, the selection and nomination of the Trustees
shall be committed to the discretion of the Rule 12b-1 Trustees.

     The Company shall preserve copies of the Plan and any related agreements
and all reports made pursuant to Section 4 hereof, for a period of not less than
six years from the date of effectiveness of the Plan, such agreements or

                                   (the Fund)

                AMENDED AND RESTATED PLAN PURSUANT TO RULE 18F-3

      The Fund hereby adopts this plan pursuant to Rule 18f-3 under the
Investment Company Act of 1940 (the 1940 Act), setting forth the separate
arrangement and expense allocation of each class of shares in each investment
portfolio (each a Portfolio). Any material amendment to this plan is subject to
prior approval of the Board of Trustees, including a majority of the independent
Trustees. The Fund currently offers Class I and Class Z Shares.

                              CLASS CHARACTERISTICS

CLASS A SHARES:     Class A shares are subject to a distribution and/or service
                    fee pursuant to Rule 12b-1 under the 1940 Act (Rule 12b-1
                    fee) not to exceed .30 of 1% per annum of the average daily
                    net assets of the class.

CLASS B SHARES:     Class B shares are not subject to an initial sales charge
                    but are subject to a high contingent deferred sales charge
                    (declining from 5% to zero over a six-year period) which
                    will be imposed on certain redemptions and a Rule 12b-1 fee
                    not to exceed 1% per annum of the average daily net assets
                    of the class. The contingent deferred sales charge is waived
                    for certain eligible investors. Class B shares automatically
                    convert to Class A shares approximately seven years after
                    purchase.

CLASS C SHARES:     Class C shares are subject to a low initial sales charge and
                    a 1% contingent deferred sales charge which will be imposed

                    purchase and a Rule 12b-1 fee not to exceed 1% per annum of
                    the average daily net assets of the class.

                    contingent deferred sales charge nor are they subject to any
                    Rule 12b-1 fee. Class I shares, are subject to minimal
                    transfer agency fees or expenses.

                         INCOME AND EXPENSE ALLOCATIONS

     Income, any realized and unrealized capital gains and losses, and expenses
     not allocated to a particular class of a Portfolio will be allocated to
     each class of such Portfolio on the basis of the net asset value of that
     class in relation to the net asset value of the Portfolio.

                           DIVIDENDS AND DISTRIBUTIONS

     Dividends and other distributions paid by each Portfolio to each class of
     shares, to the extent paid, will be paid on the same day and at the same
     time, and will be determined in the same manner and will be in the same
     amount, except that the amount of the dividends and other distributions
     declared and paid by a particular class of the Portfolio may be different
     from that paid by another class of the Portfolio because of Rule 12b-1 fees
     and other expenses borne exclusively by that class.

                               EXCHANGE PRIVILEGE

     Holders of Class A Shares, Class B Shares, Class C Shares, Class Z Shares
     and Class I Shares shall have such exchange privileges as set forth in the
     Portfolio's current prospectus. Exchange privileges may vary among classes
     and among holders of a Class.

                               CONVERSION FEATURES

     Class B shares will automatically convert to Class A shares on a quarterly
     basis approximately seven years after purchase. Conversions will be
     effected at relative net asset value without the imposition of any
     additional sales charge.

                                     GENERAL

A.   Each class of shares shall have exclusive voting rights on any matter
     submitted to shareholders that relates solely to its arrangement and shall
     have separate voting rights on any matter submitted to shareholders in
     which the interests of


                                       2
<PAGE>


     one class differ from the interests of any other class.

B.   On an ongoing basis, the Trustees, pursuant to their fiduciary
     responsibilities under the 1940 Act and otherwise, will monitor the Fund
     for the existence of any material conflicts among the interests of its
     several classes. The Trustees, including a majority of the independent
     Trustees, shall take such action as is reasonably necessary to eliminate
     any such conflicts that may develop. Prudential Investments Fund Management
     LLC, the Fund's Manager, will be responsible for reporting any potential or
     existing conflicts to the Trustees.

     Portfolio of the Fund, the methodology and procedures for calculating the
     net asset value and dividends/distributions of the Fund's several classes
     and the proper allocation of income and expenses among such classes will be
     examined annually by the Fund's independent auditors who, in performing
     such examination, shall consider the factors set forth in the relevant
     auditing standards adopted, from time to time, by the American Institute of
     Certified Public Accountants.
