Investment Goals and Style
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 that currently is the Lehman Brothers
Aggregate Index (the Index). The Index is composed of
U.S. government securities, investment-grade corporate
bonds, mortgage-backed securities, and asset-backed
securities--all of which must be investment grade and pay
a fixed interest rate. The difference between the Fund's
return and that of the Index is primarily due to fees and
management expenses. There can be no assurance that the
Fund will achieve its investment objective.

Prudential Bond Market Index Fund

Message From the Fund's President    May 24, 2000

Dear Shareholder,
On May 24, 2000, the Board of Trustees of Prudential
Index Series Fund for Prudential Bond Index Fund decided
that it was in our shareholders' best interest to
liquidate the Fund as soon as possible, but no later than
September 29, 2000. The decision to liquidate was based
upon the determination that over its lifetime, the Fund
was unable to gather enough assets to operate
efficiently. You should receive further communication
about this decision shortly.
The Fund's Class Z shares returned 1.88% for the six
months that ended on March 31, 2000, which was below the
2.08% return on the Lehman Brothers Aggregate Bond Index,
but above the 1.53% return on the Lipper Intermediate
U.S. Government Fund Average.
The low returns of the Fund, the Lehman Index, and the
Lipper Average reflect a period during which several
variables affected the U.S. bond markets. For example,
the fixed-income markets had to contend with repeated
increases in short-term interest rates by the Federal
Reserve, as well as technical factors that created
imbalances in the supply and demand for certain types of
debt securities. The following report examines these
trends during our six-month review period, and explains
how the Fund was positioned accordingly.
Thank you for your continued confidence in Prudential
mutual funds.

Sincerely,

John R. Strangfeld, President
Prudential Index Series Fund

Investment Adviser's Report

Dear Shareholder,
There was rarely a dull moment in the U.S. bond markets
during the six months that ended on March 31, 2000.
Besides a trend toward higher interest rates in the
United States, bond investors dealt with a rapidly
shrinking supply of longer-term U.S. Treasury securities
and a legislative proposal to end the federal
government's implicit support of the nation's two largest
buyers of home mortgages. These developments heightened
volatility in the domestic fixed-income markets.
Interest-rate fears deepened on October 5, 1999, when
Federal Reserve policy makers announced they were leaning
toward tightening monetary policy. The Fed had already
raised short-term rates twice in the summer of 1999,
hoping that higher borrowing costs would slow U.S.
economic activity and prevent rising inflation. But the
central bankers remained so concerned about economic
conditions that they stood ready to increase rates again,
if necessary.
In anticipation of the next rate hike, investors began to
drive bond yields higher, which caused their prices to
fall. On November 16, 1999, the Fed boosted its target
for the federal funds rate (the rate U.S. banks charge
each other for overnight loans) by a quarter of a
percentage point to 5.50%.
Its discount rate on banks that borrow from the Federal
Reserve system was increased to 5.00% from 4.75%.
Prices of longer-term Treasuries climbed...
Prices in U.S. fixed-income markets continued to decline,
pushing up the
30-year Treasury bond yield to 6.74% in mid-January 2000--
its highest level during our six-month review period.
However, the sell-off soon turned into a powerful rally,
at least for longer-term Treasuries.
The U.S. Treasury Department announced it would issue
fewer of its longer-term securities because of the
growing federal budget surplus and a reduced need to sell
new debt. It also commenced its program to buy back
$30 billion of older, mostly longer-term Treasuries by
the end of 2000.

Prudential Bond Market Index Fund

Investment Adviser's Report

The buyback amount is a small portion of the more than
$3.3 trillion in publicly traded U.S. government debt.
Nevertheless, the prospect of a declining supply of
longer-term Treasuries set off a stampede to buy them.
This trend drove the price of 30-year Treasury bonds so
high that their yield slid below 6.00%, which was lower
than the yield on two-year Treasury notes. This anomaly
is called an inversion of the yield curve, which is a
graph that depicts yields on Treasuries from the shortest
to the longest maturity. Although an inverted yield curve
typically signals an impending economic recession, we
believe it occurred this time primarily because the
demand for longer-term Treasuries exceeded the supply.
 ...leaving other U.S. bond markets in the dust
Other U.S. fixed-income markets could not keep up with
the rally in longer-term Treasuries. For example,
investment-grade corporate bonds returned only 1.46% for
the six months that ended on March 31, 2000, compared
with 3.02% for Treasuries. Investor demand for
investment-grade corporate bonds faded amid concern that
the Fed might raise rates enough to materially slow U.S.
economic growth and hurt corporate credit quality. The
central bank engineered quarter-point rate hikes in
February and March 2000. These moves raised the federal
funds rate to 6.00% and its discount rate to 5.50%.
Clinton support of legislative proposal rocked
mortgage-backed securities
Besides the changes in monetary policy, there was also
concern about the remarks of a U.S. Treasury official who
said the Clinton administration backs a bill that would
end implicit government support for Fannie Mae and
Freddie Mac. These two government-sponsored enterprises
buy select mortgages from financial institutions and
package the mortgages into securities that are sold to
investors by Wall Street brokerage firms.

Neither Fannie Mae's nor Freddie Mac's mortgage-backed
securities are backed by the full faith and credit of the
U.S. government. However, both have a line of credit from
the U.S. Treasury that can be drawn on in a crisis. The
possibility that this line of credit may be repealed led
some investors to sell the mortgage-backed securities and
bonds of Fannie Mae and Freddie Mac. For the six-month
period, mortgage-backed securities returned a modest
1.77%.
Looking Ahead
On May 16, 2000, the Fed increased the federal funds rate
and its discount rate by half of a percentage point to
6.50% and 6.00%, respectively. We believe the central
bank will continue to tighten monetary policy by another
half of a percentage point this year. Because of the
Fed's repeated efforts, we expect U.S. economic growth to
moderate slightly and inflation to taper off in the
second half of the year.
Under these more favorable economic conditions,
investment-grade corporate bonds, mortgage-backed
securities, federal agency securities, and asset-backed
securities should perform better than Treasuries later in
the year. Their improved performance is all the more
likely because these bond markets cheapened substantially
relative to Treasuries in the first quarter of 2000.

             Notes to Financial Statements (Unaudited)
      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, one of which is Prudential
Bond Market Index Fund (the 'Fund').
      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 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
mean between the most recently quoted bid and asked prices on 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 mean between the most
recently quoted bid and asked prices on 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 manager or subadviser, represents
fair value, are valued by the Valuation Committee or Board of Trustees in
consultation with the manager and the subadviser.
      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
    14

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 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
                                                                          15

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 services of
PIC, the cost of compensation of officers of the Fund, occupancy and certain
clerical and bookkeeping costs of the Fund. 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.
      PIC, PIFM and PIMS are wholly owned subsidiaries of The Prudential
Insurance Company of America ('The Prudential').
      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. For the six months ended March 31, 2000, PIFM
subsidized $50,275 of the expenses of the Fund (0.22% of the average daily net
assets or $0.011 per share).
      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.
Interest on any such borrowings will be at market rates. The purpose of the
agreement is to serve as an alternative source of funding for capital share
redemptions. The Funds pay a commitment fee of .080 of 1% of the unused portion
of credit facility. The commitment fee is accrued and paid quarterly on a pro
rata basis by the Funds. The expiration date of the SCA is March 9, 2001. Prior
to March 9, 2000, the commitment fee was .065 of 1% of the unused portion of the
credit facility. The Fund did not borrow any amounts pursuant to the SCA during
the year ended March 31, 2000.
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,
2000, the Fund incurred fees of approximately $9,200 for the services of PMFS.
As of March 31, 2000, approximately $1,500 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 investment securities, other than short-term investments,
for the six months ended March 31, 2000, were $72,912,622 and $71,502,651,
    16

respectively, which includes purchases and sales of U.S. government obligations
of $38,235,259 and $67,186,500, respectively.
      The federal income tax basis of the Fund's investments at March 31, 2000
was $52,674,381 and, accordingly, net unrealized depreciation for federal income
tax purposes was $937,557 (gross unrealized appreciation-$170,030; gross
unrealized depreciation-$1,107,587).
      For federal income tax purposes, the Fund had a capital loss carryforward
as of September 30, 1999 of $34,592 which expires in 2007. Accordingly, no
capital gains distributions are expected to be paid to shareholders until future
net gains have been realized in excess of such carryforward.
      The Fund elected, for United States Federal income tax purposes, to treat
short-term capital losses of $374,080 and long-term capital gains of $57,975
incurred in the eleven months ended September 30, 1999 as having incurred in the
current fiscal year.
      The average monthly balance of dollar rolls outstanding during the six
months ended March 31, 2000 was approximately $6,750,000.
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,
2000, the Fund had a 1.15% undivided interest in the repurchase agreements in
the joint account. This undivided interest represented $7,570,000 in principal
amount. As of such date, the repurchase agreements in the joint account and the
value of the collateral therefor were as follows:
      Bear, Stearns & Co., Inc., 6.10%, in the principal amount of $120,000,000,

Getting the Most From Your Prudential Mutual Fund

When you invest through Prudential Mutual Funds, you
receive financial advice from a Prudential Securities
Financial Advisor or Pruco Securities registered
representative. Your advisor or representative can
provide you with the following services:
There's No Reward Without Risk; but Is This Risk Worth
It?
Your financial advisor or registered representative can
help you match the reward you seek with the risk you can
tolerate. Risk can be difficult to gauge--sometimes even
the simplest investments bear surprising risks. The
educated investor knows that markets seldom move in just
one direction. There are times when a market sector or
asset class will lose value or provide little in the way
of total return. Managing your own expectations is easier
with help from someone who understands the markets and
who knows you!
Keeping Up With the Joneses
A financial advisor or registered representative can help
you wade through the numerous available mutual funds to
find the ones that fit your individual investment profile
and risk tolerance. While the newspapers and popular
magazines are full of advice about investing, they are
aimed at generic groups of people or representative
individuals--not at you personally. Your financial advisor
or registered representative will review your investment
objectives with you. This means you can make financial
decisions based on the assets and liabilities in your
current portfolio and your risk tolerance--not just based
on the current investment fad.
Buy Low, Sell High
Buying at the top of a market cycle and selling at the
bottom are among the most common investor mistakes. But
sometimes it's difficult to hold on to an investment when
it's losing value every month. Your financial advisor or
registered representative can answer questions when
you're confused or worried about your investment, and
should remind you that you're investing for the long
haul.

Investment Goals and Style
Prudential Europe Index Fund seeks to provide
investment results that correspond to the price and
yield performance of a broad-based index of stocks
of European issuers. Currently, we use the Morgan
Stanley Capital International (MSCI) Europe Index.
This Index consists of stocks in 15 countries. The
United Kingdom represented 31% of the MSCI Index on
September 30, 1999, and France and Germany together
made up more than 28%. The difference between the
Fund's return and that of the Index is primarily
management fees and expenses. There can be no
assurance that the Fund will achieve its investment
objective.

Prudential Europe Index Fund

Message From the Fund's President                  May 24, 2000
Dear Shareholder,
On May 24, 2000, the Board of Trustees of
Prudential Index Series Fund for Prudential Europe
Index Fund decided that it was in our shareholders'
best interest to liquidate the Fund as soon as
possible, but no later than September 29, 2000. The
decision to liquidate was based upon the
determination that over its lifetime, the Fund was
unable to gather enough assets to operate
efficiently. You should receive further
communication about this decision shortly.
Performance
For the six months that ended March 31, 2000,
Prudential Europe Index Fund generated a return of
17.29%, slightly trailing the 17.48% return of the
Morgan Stanley Capital International (MSCI) Europe
Index. The period under review was a volatile one.
During the final two months of 1999, the
technology, telecommunications, and media sectors
staged a worldwide rally. These sectors greatly
contributed to the Fund's return. However,
following the explosive advance, a sharp
correction--led by richly valued new economy stocks--
erased much of the gains. Share prices stabilized
somewhat at period end.
Diversification helps spread risk
The volatility in technology and telecommunications
stocks was once again evidence of the advantages of
index funds. Investors who concentrated mainly on
the "hot" sectors of the market were taken for a
heart-stopping ride. In contrast, your Fund was
broadly represented among different market sectors
and geographical regions. The diversified approach
of indexing tends to catch winners in a variety of
sectors while providing some downside cushion in
volatile markets.

Sincerely,

John R. Strangfeld, President
Prudential Index Series Fund

Investment Adviser's Report

Dear Shareholder,
Europe was characterized by active consolidation
and restructuring against the backdrop of a
strengthening but still muted economic recovery
during the six-month reporting period ended March
31, 2000. The adoption of one currency, the euro,
for much of Western Europe resulted in an improved
ability to control costs, as did productivity
gains resulting from the growth of e-commerce on
the Internet. Without regional currency differences
to complicate the process, European firms were able
to negotiate more aggressively with their suppliers
in the United States and elsewhere. The result was
a mildly deflationary environment in which prices
were falling, real incomes were rising, and there
was increasing concern among workers about job
security.
One important development during the period was a
sharply falling euro relative to both the U.S.
dollar and the Japanese yen. Although the effect of
currency fluctuations tends to be somewhat delayed,
the weaker euro made European exports more
attractive to the region's trading partners, and
was expected to provide a substantial boost to that
portion of the European economy. Interest rates in
the region edged upward, although not nearly to the
degree evident in the United States. European Union
central bank officials attempted to walk a fine
line between moderate rate increases intended to
support their weaker-than-expected currency and
keeping rates low enough to avoid derailing the
economic recovery. While European central bankers
were no doubt glad for the stimulating effects of a
weaker currency, they prefer to have a stable euro
that is neither excessively strong nor excessively
weak.
Restructuring continued apace, as an increasing
number of firms geared up to try to compete on a
pan-European basis. Consequently, the prices of
many stocks were aided by merger and acquisition
news. There was also a divergence in the
performance of new economy/old economy stocks that
paralleled that occurring in the United States. For
approximately the first month of the period, old
economy stocks--that is, shares of companies in
established industries such as industrial
equipment, transportation, energy,

                                       3

finance, and the like--were stronger performers.
However, technology, telecommunications, Internet,
and media stocks experienced a tremendous rally
during the final two months of 1999. Like their
U.S. counterparts, these stocks also experienced a
stiff correction toward the end of the period.
Nevertheless, the new economy sectors led the
Fund's German stocks to a 33.15% gain during the
period, while French stocks posted a 23.67% return.
Finland and Sweden, though much smaller components
of the Fund and the Index, also were strong, with
returns of 115.96% and 73.45%, respectively. The
United Kingdom, comprising almost one-third of the
Fund's holdings, finished with a 4.06% return. Many
U.K. stocks were adversely affected by sharply
higher interest rates, as monetary authorities
there--like the Federal Reserve Board in the United
States--sought to slow economic growth and head off
inflation. The United Kingdom also had a relatively
smaller representation of new economy stocks in the
Index than the better-performing countries, which
also hurt the Fund's returns from that region.
Telecommunications stocks from a number of
countries were among the Fund's strongest
performers. Deutsche Telecom and France Telecom
both came close to doubling in price. Finnish
telecommunications equipment provider Nokia was
another strong stock, as was Sweden's L.M.
Ericsson. Other outperformers in the sector
included Spain's Telefonica SA and Italy's Telecom
Italia Spa.
Barriers to restructuring falling
Epitomizing the new, friendlier attitude toward
consolidation in Europe, U.K. wireless telephone
provider Vodafone Airtouch made a successful
hostile bid for German competitor Mannesmann during
the period. In the past, the German government
might have blocked such a bid, but in this case the
government offered no resistance. This precedent
was widely perceived to have important implications
for restructuring initiatives across the entire
European Union. It appeared to demonstrate that
barriers to pan-European restructuring were
genuinely being phased out.

Mannesmann stock advanced sharply in response to
the takeover bid, roughly doubling during the
period.
Another potentially strong catalyst for
restructuring was revealed in December. In a move
that took most observers by surprise, the German
government proposed the elimination of the capital
gains tax. The tax was seen as a barrier to
restructuring because of the sizable capital gains
that would be recorded by firms that allowed
themselves to be bought out by other companies.
This was especially the case for the many family-
owned businesses started since the end of World War
II. Eliminating the tax would remove a powerful
disincentive to sell these companies.
Looking Ahead
The advantage of investing in an index fund is that
you don't have to try to guess where superior
performance is going to come from next. If, as
seems likely, old economy stocks come into favor
again or there is a more balanced demand for old
and new economy shares, the Fund will be positioned
to benefit. Similarly, if political considerations,
such as the German initiative to eliminate the tax
on capital gains, create a particularly favorable
environment for equities in a specific country or
region, the Fund should share in those gains. With
an asset class like stocks, which have demonstrated
a tendency to rise over the long term, one of the
keys to success is simply to be represented in a
broad range of issues. Indexing provides that
advantage.

             Notes to Financial Statements (Unaudited)
      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, one of which is the
Prudential Europe Index Fund (the 'Fund'). 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 manager or subadviser, does not represent fair value, are valued
by the Valuation Committee or Board of Trustees in consultation with the manager
or the subadviser.
      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.

             Notes to Financial Statements (Unaudited) Cont'd.
      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.
      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
                                                                          27

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:    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 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 increase accumulated net realized gain and
decrease distributions in excess of net investment income by $13,506 for
realized foreign currency losses during the six

months ended March 31, 2000. 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 services of
PIC, the cost of 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. For the six months ended March 31, 2000, PIFM
subsidized $119,436 of the expenses of the Fund (0.48% of average daily net
assets, or $0.06 per share).
      The Fund 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, PIMS and PIC are wholly owned subsidiaries of The Prudential
Insurance Company of America ('Prudential').
      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.
Interest on any such borrowings will be at market rates. The purpose of the
agreement is to serve as an alternative source of funding for capital share
redemptions. The Funds pay a commitment fee of .080 of 1% of the unused portion
of the credit facility. The commitment fee is accrued and paid quarterly on a
pro rata basis by the Funds. The expiration date of the SCA is March 9, 2001.
Prior to March 9, 2000, the commitment fee was .065 of 1% of the unused portion
of the credit facility. The Fund did not borrow any amounts pursuant to the SCA
during the year ended March 31, 2000.
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,
                                                                          29

2000, the Fund incurred fees of approximately $2,600 for the services of PMFS.
As of March 31, 2000, approximately $500 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, 2000 were $1,582,801 and $1,324,590,
respectively.
      The United States federal income tax cost basis of the Fund's investments
at March 31, 2000 was $19,480,382 and, accordingly, net unrealized appreciation
for federal income tax purposes was $6,876,573 (gross unrealized
appreciation--$8,553,036; gross unrealized depreciation--$1,676,463).
      At March 31, 2000, the Fund had open purchases of 10 CAC 40 and 10 FTSE
100 financial futures contracts expiring on June 17, 2000.

Getting the Most From Your Prudential Mutual Fund

Some mutual fund shareholders won't ever read this--
they don't read annual and semiannual reports. It's
quite understandable. These annual and semiannual
reports are prepared to comply with federal
regulations, and are often written in language that
is difficult to understand. So when most people run
into those particularly daunting sections of these
reports, they don't read them.
We think that's a mistake
At Prudential Mutual Funds, we've made some changes
to our report to make it easier to understand and
more pleasant to read. We hope you'll find it
profitable to spend a few minutes familiarizing
yourself with your investment. Here's what you'll
find in the report:
Performance at a Glance
Since an investment's performance is often a
shareholder's primary concern, we present
performance information in two different formats.
You'll find it first on the "Performance at a
Glance" page where we compare the Fund and the
comparable average calculated by Lipper, Inc., a
nationally recognized mutual fund rating agency. We
report both the cumulative total returns and the
average annual total returns. The cumulative total
return is the total amount of income and
appreciation the Fund has achieved in various time
periods. The average annual total return is an
annualized representation of the Fund's
performance. It gives you an idea of how much the
Fund has earned in an average year for a given time
period. Under the performance box, you'll see
legends that explain the performance information,
whether fees and sales charges have been included
in returns, and the inception dates for the Fund's
share classes.
See the performance comparison charts at the back
of the report for more performance information.
Please keep in mind that past performance is not
indicative of future results.

Performance review
The portfolio manager, who invests your money for
you, reports on successful--and not-so-successful--
strategies in this section of your report. Look for
recent purchases and sales here, as well as
information about the sectors the portfolio manager
favors, and any changes that are on the drawing
board.
Portfolio of Investments
This is where the report begins to appear
technical, but it's really just a listing of each
security held at the end of the reporting period,
along with valuations and other information. Please
note that sometimes we discuss a security in the
Performance Review that doesn't appear in this
listing because it was sold before the close of the
reporting period.
Statement of Assets and Liabilities
The balance sheet shows the assets (the value of
the Fund's holdings), liabilities (how much the
Fund owes), and net assets (the Fund's equity, or
holdings after the Fund pays its debts) as of the
end of the reporting period. It also shows how we
calculate the net asset value per share for each
class of shares. The net asset value is reduced by
payment of your dividend, capital gain, or other
distribution, but remember that the money or new
shares are being paid or issued to you. The net
asset value fluctuates daily, along with the value
of every security in the portfolio.
Statement of Operations
This is the income statement, which details income
(mostly interest and dividends earned) and
expenses (including what you pay us to manage your
money). You'll also see capital gains here--both
realized and unrealized.

Statement of Changes in Net Assets
This schedule shows how income and expenses
translate into changes in net assets. The Fund is
required to pay out the bulk of its income to
shareholders every year, and this statement shows
you how we do it (through dividends and
distributions) and how that affects the net assets.
This statement also shows how money from investors
flowed into and out of the Fund.
Notes to Financial Statements
This is the kind of technical material that can
intimidate readers, but it does contain useful
information. The Notes provide a brief history and
explanation of your Fund's objectives. In addition,
they outline how Prudential Mutual Funds prices
securities. The Notes also explain who manages and
distributes the Fund's shares and, more
importantly, how much they are paid for doing so.
Finally, the Notes explain how many shares are
outstanding and the number issued and redeemed over
the period.
Financial Highlights
This information contains many elements from prior
pages, but on a per-share basis. It is designed to
help you understand how the Fund performed, and to
compare this year's performance and expenses to
those of prior years.
Independent Auditor's Report
Once a year, an outside auditor looks over our
books and certifies that the information is fairly
presented and complies with generally accepted
accounting principles.
Tax Information
This is information that we report annually about
how much of your total return is taxable. Should
you have any questions, you may want to consult a
tax adviser.

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

Investment Goals and Style
Prudential Pacific Index Fund seeks to provide investment
results that correspond to the price and yield
performance of a broad-based index of stocks of Pacific
region issuers. Currently, we use the Morgan Stanley
Capital International (MSCI) Pacific Free Index. ("Free"
means that it includes companies that are open to foreign
investors.) Over the past year, the MSCI Pacific Free
Index included stocks in Japan, Australia, Hong Kong,
Singapore, and New Zealand. The difference between the
Fund's return and that of the Index is primarily
management fees and expenses. There can
be no assurance that the Fund will achieve its investment
objective.

Prudential Pacific Index Fund

Message From the Fund's President   As of May 24, 2000

Dear Shareholder,
On May 24, 2000, the Board of Trustees of Prudential
Index Series Fund for Prudential Pacific Index Fund
decided that it was in our shareholders' best interest to
liquidate the Fund as soon as possible, but no later than
September 29, 2000. The decision to liquidate was based
upon the determination that over its lifetime, the Fund
was unable to gather enough assets to operate
efficiently. You should receive further communication
about this decision shortly.
Performance
For the six months that ended March 31, 2000, Prudential
Pacific Index Fund finished with a return of 13.67%,
compared to 15.58% for the Morgan Stanley Capital
International (MSCI) Pacific Free Index. It was a
volatile period marked by an explosive advance that was
led by the technology and telecommunications sectors,
followed by a sharp correction that erased much of the
gains. Share prices stabilized somewhat at period end. A
slightly stronger yen added to the Fund's returns in U.S.
dollar terms, but currency fluctuation played a much less
significant role than in the prior fiscal period.
Diversification helps spread risk
The volatility in technology and telecommunications
stocks was once again evidence of the advantages of index
funds. Investors who concentrated mainly on the "hot"
sectors of the market were taken for a heart-stopping
ride. In contrast, your Fund owned a mix of new and old
economy stocks. The diversified approach of indexing
tends to catch winners in a variety of sectors while
providing some downside cushion in volatile markets.

Sincerely,

John R. Strangfeld, President
Prudential Index Series Fund

Investment Adviser's Report

Dear Shareholder,
During the six-month reporting period ended March 31,
2000, the Japanese economy provided evidence that the
country was making slow progress toward better times.
However, the signals continued to be very mixed for the
country that comprises roughly three-fourths of the Fund
and the Morgan Stanley Capital International (MSCI)
Pacific Free Index. After cheering investors with two
consecutive quarters of positive GDP growth in 1999, the
latest two quarters have seen negative growth, indicating
an economy that is still very fragile. Consumer spending
was fairly strong, but consumers were preoccupied with
bargain hunting, which helps discount retailers but hurts
the traditional department stores. The government
appeared committed to jump-starting the economy with
liberal spending policies, but Japan's tradition of
spending freely in areas such as capital spending (on
average, the percentage allocated to capital projects by
Japan's government is about double the comparable figure
in the U.S. budget) has in the past resulted in
substantial waste and misallocation of capital. Thus, as
the bloated parts of the budget are pared back and
spending for information technology increases, there are
likely to be further bumps along the way in GDP growth.
Nonetheless, there were some solid indications of
progress. More and more companies appeared to be engaged
in serious restructuring, if only as a result of
heightened competitive pressures. Moreover, the
government recently passed legislation that will make it
easier for foreign companies to acquire Japanese
companies--a major breakthrough for a country that in the
past turned down repeated requests from its trading
partners for such a law. This legislation followed
closely on the heels of another law that facilitated
stock buybacks--a tool frequently employed by Western
corporations to increase shareholder value. Consequently,
while maximizing shareholder value is still not second
nature for many Japanese companies--especially those
controlled by a single family--it is becoming increasingly
accepted as a requirement of doing business in a globally
competitive world.

Prudential Pacific Index Fund

Investment Adviser's Report

Export-related stocks shine
Japanese stocks, reflecting investors' expectations of
improving economic conditions, did moderately well, aided
(in U.S. dollar terms) by modest appreciation in the yen
against the dollar. There were several areas of strength
in the Fund's Japanese holdings, which returned 16.33%
during the period. Export-related companies, benefiting
from a relatively stable yen and strong demand from the
United States and Europe, performed well. Examples
included Toyota, Sony, Kyocera, and Canon. Small stocks
representing the new economy also did well, though a
sharp correction during the second half of the period
offset many of the gains in these sectors. Japanese
retail investors returned to the stock market in force
and, like their counterparts in the United States and
Europe, focused on two sectors that outshone all others
on a worldwide basis, especially during the final quarter
of 1999: technology and telecommunications. Cellular
phone equipment and service providers were particularly
strong, driven by the popularity of recently introduced
phones with Internet capabilities.

Enthusiastic buying in these sectors drove share prices
to dizzying heights, and created huge discrepancies
between the leaders and the laggards in the Japanese
market. A decline in new economy stocks also occurred,
paralleling similar corrections in other markets, but the
Japanese pullback began earlier and was intensified by
additional selling from investors who had bought high-
flying stocks on margin. Nevertheless, stocks such as
Softbank, an Internet investment company, managed to
finish the period with triple-digit gains. Specialty and
discount retailers also did well, as did securities
firms, reflecting investors' enthusiastic participation
in the markets.

Looking elsewhere in the Pacific Basin, the Hong Kong
component of the Fund did well, gaining 30.44%. The
market there appears to be in transition. When Hong Kong
was under British rule, banks, property companies, and
conglomerates dominated the market. Lately, the
traditional favorites have had problems, and stocks more
representative of Mainland China--such as China Telecom--
have come to the fore. Prices for real estate and other
commodities

4

www.prudential.com                   (800) 225-1852

are still too high in Hong Kong, and will probably have
to come down to levels that reflect the new realities of
the region. Currently there are plans to increase the
weighting of Hong Kong and Taiwanese stocks in the Index.
Australia, comprising on average 7.4% of the Fund and the
Index during the
period, suffered as the rest of the region's prospects
improved. During Asia's financial crisis, Pacific Basin
investors retreated to the relative safety of Australian
stocks, driving up share prices. When prospects for the
region improved, investors looked for greener pastures in
Japan, Hong Kong, and other markets. Finally, in smaller
markets such as Indonesia, there was a realization that
the road to recovery would be longer and harder than
previously thought.
Looking ahead
Structural problems remain in Japan, but solid attempts
by the government to rid the economy of its
inefficiencies represent cause for optimism. Another
favorable influence on Japan is the fact that the rest of
Asia is growing vigorously once again. Furthermore, there is
evidence that prices and volume in the Japanese
commercial real estate market are turning up--an
indication that the long bear market there may be over.
An improvement in the real estate market would be very
positive for Japanese banks, whose problems with bad real
estate loans are by now legendary.
Finally, these developments are occurring at a time when
investors worldwide appear to be reconsidering the values
inherent in the old economy, which includes industries
such as finance and industrial manufacturing. Buying
stocks simply because of their association with the
Internet, in the absence of earnings, may become less
fashionable than was the case during much of the period.
Technology investing will not simply go away, of course,
but investors, chastened by a stiff correction and the
accompanying shrinkage in their accounts, are likely to
be more value-conscious in the future than they have been
recently.

             Notes to Financial Statements (Unaudited)
      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, one of which is the
Prudential Pacific Index Fund (the 'Fund').
      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 manager or subadviser, does not represent fair value, are
valued by the Valuation Committee or Board of Trustees in consultation with the
manager and the subadviser.
      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.

             Notes to Financial Statements (Unaudited) Cont'd.
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
                                                                          25

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 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 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

to decrease distribution in excess of net investment income and to decrease
accumulated net realized gain on investments by $158,683, relating to net
realized foreign currency gains. 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 services of
PIC, the cost of 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. For the six months ended March 31, 2000, PIFM
subsidized $111,089 of the expenses of the Fund (0.62% of average net assets
annualized or $0.04 per share).
      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 wholly owned subsidiaries of The Prudential
Insurance Company of America ('The Prudential').
      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.
Interest on any such borrowings will be at market rates. The purpose of the
agreement is to serve as an alternative source of funding for capital share
redemptions. The Funds pay a commitment fee of .080 of 1% of the unused portion
of the credit facility. The commitment fee is accrued and paid quarterly on a
pro rata basis by the Funds. The expiration date of the SCA is March 9, 2001.
Prior to March 9, 2000, the commitment fee was
                                                                          27

 .065 of 1% of the unused portion of the credit facility. The Fund did not borrow
any amounts pursuant to the SCA during the six months ended March 31, 2000.
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,
2000, the Fund incurred fees of approximately $1,900 for the services of PMFS.
As of March 31, 2000, approximately $400 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, 2000 were $1,224,224 and $6,360,424,
respectively.
      The cost basis of investments for federal income tax purposes at March 31,
2000 was $27,464,702 and, accordingly, net unrealized appreciation for federal
income tax purposes was $6,664,936 (gross unrealized appreciation--$9,798,236;
gross unrealized depreciation--$3,133,300).
      For Federal income tax purposes, the Fund had a capital loss carryforward
as of September 30, 1999 of $450,909 which expires in 2007. Accordingly, no
capital gains distributions are expected to be paid to shareholders until future
net gains have been realized in excess of such carryforward.
      The Fund will elect, for United States Federal income tax purposes, to
treat long-term capital losses of $118,458 incurred in the eleven months ended
September 30, 1999 as having been incurred in the current fiscal year.
      During the six months ended March 31, 2000, the Fund entered into
financial futures contracts. Details of open contracts as of March 31, 2000 are
as follows:

Getting the Most From Your Prudential Mutual Fund

When you invest through Prudential Mutual Funds, you
receive financial advice from a Prudential Securities
Financial Advisor or Pruco Securities registered
representative. Your advisor or representative can
provide you with the following services:
There's No Reward Without Risk; but Is This Risk Worth
It?
Your financial advisor or registered representative can
help you match the reward you seek with the risk you can
tolerate. Risk can be difficult to gauge--sometimes even
the simplest investments bear surprising risks. The
educated investor knows that markets seldom move in just
one direction. There are times when a market sector or
asset class will lose value or provide little in the way
of total return. Managing your own expectations is easier
with help from someone who understands the markets and
who knows you!
Keeping Up With the Joneses
A financial advisor or registered representative can help
you wade through the numerous available mutual funds to
find the ones that fit your individual investment profile
and risk tolerance. While the newspapers and popular
magazines are full of advice about investing, they are
aimed at generic groups of people or representative
individuals--not at you personally. Your financial advisor
or registered representative will review your investment
objectives with you. This means you can make financial
decisions based on the assets and liabilities in your
current portfolio and your risk tolerance--not just based
on the current investment fad.
Buy Low, Sell High
Buying at the top of a market cycle and selling at the
bottom are among the most common investor mistakes. But
sometimes it's difficult to hold on to an investment when
it's losing value every month. Your financial advisor or
registered representative can answer questions when
you're confused or worried about your investment, and
should remind you that you're investing for the long
haul.

Investment Goals and Style
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
capitalization stocks. Currently we use the
Standard & Poor's SmallCap 600 Stock Index (S&P
SmallCap 600 Index). The S&P SmallCap 600 Index
consists of 600 U.S. stocks selected to be
representative of the industry composition of the
small-cap market. On March 31, their individual
market values ranged from $17 million to $6,080
million, with a median of $466 million. Differences
between the Fund's return and that of the Index are
due in part to management fees and expenses. Small-
cap stocks have limited marketability and may be
subject to more abrupt or erratic market movements
than large-cap stocks. There can be no assurance
that the Fund will achieve its investment
objective.

least 75% of their equity assets in companies with
market capitalizations (on a three-year weighted
basis) of less than 250% of the dollar-weighted
median market capitalization of the S&P SmallCap
600 Index. Small-Cap Core funds have wide latitude
in the companies in which they invest. These funds
will normally have an average price/earnings ratio,
price-to-book ratio, and three-year earnings growth
figure, compared to the U.S. diversified small-cap
funds universe average.

capitalization-weighted index comprised of 600

unmanaged, and the total return includes the
reinvestment of all dividends, but does not reflect
the payment of transaction costs and advisory fees
associated with an investment in the Fund.

Prudential Small-Cap Index Fund
Message From the Fund's President          May 24, 2000

Dear Shareholder,
On May 24, 2000, the Board of Trustees for
Prudential Small-Cap Index Fund decided that it was
in our shareholders' best interest to liquidate the
Fund as soon as possible, but no later than
September 29, 2000. The decision to liquidate was
based upon the determination that over its
lifetime, the Fund was unable to gather enough
assets to operate efficiently. You should receive
further communication about this decision shortly.
For the first time since a global financial panic
began in Asia in 1997, Standard & Poor's SmallCap
600 Stock Index had two successive positive
quarters--the six months ended March 31, 2000--
providing the basis for a 19.09% half-year return
for the Fund. This exceeded the return for the full
12 months of its last fiscal year. Performance came
not just from the new economy stocks in
communications services, technology, and
biotechnology, but also from energy, capital goods,
and financial stocks, although many of the
strongest capital goods returns were technology-
related.
In the second half of this reporting period,
Standard & Poor's small-cap index had more than
doubled the return of its large-cap counterpart.
With large-cap technology stocks at very high
prices, investors began to look among smaller firms
for potential growth. In the first quarter of 1999,
small-cap technology stocks moved up sharply, led
by computer-related industries. Then, biotechnology
and telecommunications stocks took up the lead.
This period was marked by dramatic and frequent
changes in the fortunes of particular companies,
sectors, and investment styles. Such shifts in
market sentiment are not unusual in the securities
markets and are why werecommend that investors
maintain a broadly diversified portfolio. A
diversified portfolio is likely to be less
volatile than any of its components.


Yours sincerely,

John R. Strangfeld, President
Prudential Index Series Fund

Investment Adviser's Report

Dear Shareholder,
The technology sector now comprises more than a
quarter of the S&P SmallCap 600 Index market
capitalization (the total value of outstanding
shares). For much of our reporting period--the six
months ended March 31, 2000--exuberant buying drove
up technology stocks. The sector's advance was
driven by technological service companies such as
Mercury Interactive (tools for testing enterprise-
scale software applications), Clarify (front-office
software), and Macromedia (Web design and graphics
tools). The stocks of these three firms more than
doubled in price during the half-year.
The tiny (three-company) communications services
sector had the largest average gain, but a larger
contribution to the overall Index came from the
healthcare sector. Biotechnology companies--led by
Idec Pharmaceuticals and Incyte Pharmaceuticals--
soared.
The technology and telecommunications sectors and
the biotech group of the healthcare sector have
been the market darlings. They make up what has
been called the "new economy."  Market swings,
particularly in March 2000, tended to alternate
between new economy and old economy stocks.
This reporting period also saw a rebound in
financial stocks, such as U.S. Trust and Silicon
Valley Bancshares. As the name of the latter
suggests, the impact of the rapid growth of new
economy companies contributes to growth in other
sectors. The customers of Silicon Valley Bancshares
are primarily in technology and life sciences (as
well as wine and entertainment). Similarly, the
largest gains in the capital goods sector were made
by firms with names such as Valence Technology,
Three-Five Systems, and C-Cor.Net.

Prudential Small-Cap Index Fund
Investment Adviser's Report

Although more sectors advanced than retreated over
the reporting period, consumer-oriented sectors,
utilities, and basic materials still had negative
average returns over the six months. However, March
performance almost represented an inversion of the
sector performance profile for the first two
months. The previously market-leading sectors came
off their highs, while formerly lagging sectors had
positive returns. The month was extraordinarily
volatile. Such volatility illustrates the advantage
of owning an index fund. As former market leaders
drop to the bottom of the pack, an investor who was
concentrated in one sector would experience sharp
changes in fortune. We are unlikely to have seen
the last of the technology sector's strong gains,
but they well may come after the rest of the market
has caught up a bit.
Looking Ahead
The market appears to be correcting some of the
extraordinary gains of the past half-year.
Volatility is increasing. The gains of some of the
high-flying Internet stocks have "come back to
earth." Market leadership seems to be continuing to
alternate between new economy stocks and previously
neglected old economy stocks.
One can predict neither the market's change in
sentiment nor the rapidity of those changes. A
portfolio representative of a broad spectrum of
market capitalization and industry groups is a wise
precaution. An index fund enables one to
participate in the market advances, regardless of
whichever sector leads.

             Notes to Financial Statements (Unaudited)
      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, one of which is the
Prudential Small-Cap Index Fund (the 'Fund').
      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 for that purpose.
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 traded on an exchange and NASDAQ
National Market System are valued at the last sale price on such exchange system
or, if there was no sale on such day, at the mean between the last bid and asked
prices, or at the bid price in the absence of an asked price. Corporate bonds
(other than convertible) and U.S. government securities are valued on the basis
of valuations provided by an independent pricing agent or principal market
maker. Convertible debt securities are valued at the mean between the last
reported bid and asked prices provided by principal market makers. Options are
valued at the mean between the most recently quoted bid and asked prices on the
exchange on which they are traded. Futures contracts and options thereon are
valued at their last sale prices as of the close of trading on the applicable
commodities exchange or board of trade or, if there was no sale on such day, at
the mean between the most recently quoted bid and asked prices. Securities for
which reliable market quotations are not readily available, or for which the
pricing agent or principal market maker does not provide a valuation, in the
judgement of the manager or subadviser, that represents fair value, are valued
by the Valuation Committee or Board of Trustees in consultation with the manager
or subadviser.
      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, 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
                                                                          29

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:    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 income 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 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
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 .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 daily net assets of the Fund. For the six months
ended March 31, 2000, PIFM subsidized $92,642 of the expenses of the Fund (0.60%
of the average daily net assets of the Fund; $.03 per share.)
      The Fund 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.
      PIC, PIFM and PIMS are wholly owned subsidiaries of The Prudential
Insurance Company of America ('Prudential').
      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.
Interest on any such borrowings will be at market rates. The purpose of the
agreement is to serve as an alternative source of funding for capital share
redemptions. The Funds pay a commitment fee of .080 of 1% of the unused portion
of the credit facility. The commitment fee is accrued and paid quarterly on a
pro rata basis by the Funds. The expiration date of the SCA is March 9, 2001.
Prior to March 9, 2000, the commitment fee was .065 of 1% of the unused portion
of the credit facility. The Fund did not borrow any amounts pursuant to the SCA
during the six months ended March 31, 2000.
                                                                          31

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,
2000, the Fund incurred fees of approximately $5,800 for the services of PMFS.
As of March 31, 2000, 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, 2000 aggregated $5,355,907 and $5,890,273,
respectively.
      On March 31, 2000, the Fund held a financial futures contract on the
Russell 2000 expiring June 2000. The cost of such contracts was $304,125. The
value of the contracts on March 31, 2000 was $272,675, thereby resulting in an
unrealized loss of $31,450.
      The cost basis of investments for federal income tax purposes is
$29,501,178 and, accordingly, as of March 31, 2000, net unrealized appreciation
for federal income tax purposes was $2,979,148 (gross unrealized
appreciation--$8,586,142; gross unrealized depreciation--$5,606,994).
Note 5. Joint Repurchase Agreement Account
The Fund, 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, 2000, the Fund
had a .084% undivided interest in the repurchase agreements in the joint
account. The undivided

Investment Goals and Style
Prudential Stock Index Fund seeks 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 S&P 500 Index is
widely regarded as representative of the performance of
the U.S. stock market as a whole, and comprises stocks
representing more than 80% of the total market value of
all publicly traded U.S. common stocks. The difference
between the Fund's return and that of the Index is
primarily management fees and expenses. There can be no
assurance that the Fund will achieve its investment
objective.

Prudential Stock Index Fund
Message From the Fund's President          May 16, 2000

Dear Shareholder,
Technology and telecommunications stocks led the way to
another strong performance for Prudential Stock Index
Fund Class Z shares, which returned 17.30% during the
six-month period ended March 31, 2000. The Fund's
benchmark, the Standard & Poor's 500 Composite Stock
Price Index (S&P 500), returned 17.50% over the same
period. The market advance was fairly narrow because many
sectors were adversely affected by rising interest rates.
Yet the Fund, with a significant representation in the
most favored sectors, was able to participate in the
rally.
One of the most important benefits of index investing is
the ability to "catch the wave" of whatever sector is
working at the moment while maintaining investments in a
broad range of other sectors. If you are invested in an
index fund, you don't have to worry about whether the
current trend favors "old" or "new" economy, technology
or financial services, value or growth. You know that
your fund has investments in all of these areas, and that
you will likely benefit from share price appreciation in
any of them.
Thank you for your confidence in Prudential mutual funds.

Sincerely,

John R. Strangfeld, President
Prudential Index Series Fund

Investment Adviser's Report

Dear Shareholder,
The beginning of our reporting period on October 1, 1999,
occurred near an important intermediate-term bottom in
the S&P 500, providing yet another example of the recent
tendency of the market to find a bottom around that time
of year. Since establishing an all-time intraday high of
1420.14 on July 19, the Index has experienced volatility
as it attempts to digest increases in short-term interest
rates by the Federal Reserve Board in June and August.
The Fed sought to head off a resurgence of inflation by
using higher rates to slow economic growth, as evidence
continued to point to a more rapidly growing economy than
had been anticipated earlier in the year.
Report of a 1.1% rise in September's producer price
index--its biggest gain in nine years--had investors in a
negative frame of mind around mid-October. However,
subsequent reports on consumer prices, the employment
cost index, and other inflation gauges failed to confirm
the presence of any significant inflation, setting the
stage for a rally in both stock and bond markets. As it
turned out, the rally in stocks was the beginning of a
significant advance that carried through the end of the
year. During this phase, technology, telecommunications,
media, and biotechnology were the clear favorites. The
speculative froth in the market was reflected in the
sizzling market for Internet-related initial public
offerings (IPOs), many of which soared to stratospheric
levels on their first day of trading.
As expected, the Fed raised interest rates again in
November, but investors kept buying stocks in the most
favored sectors, perhaps feeling that rates would
stabilize now that the Fed had offset the three decreases
in rates that had occurred in the fall of 1998. Although
financial services stocks were not particularly strong
during this rally, there was one bright spot for this
sector. On November 12, President Clinton signed into law
the Gramm-Leach-Bliley Act. This legislation repealed the
Glass-Steagall Act enacted in 1933, which barred
commercial banks from merging with brokerage firms,
investment banks, and insurance companies. The new law
was widely expected to precipitate a fresh round of
mergers and acquisitions in the finance sector.

Prudential Stock Index Fund

Investment Adviser's Report

The S&P 500's positive momentum abruptly vanished at the
outset of the new year. In the face of the realization
that the Fed was probably not
finished raising interest rates, buying became even more
narrowly concentrated on the "new economy" stocks in the
technology, telecommunications, and media sectors. This
preoccupation led to a curious divergence in the market.
Many days in January and February, the Dow Jones
Industrial Average--dominated by finance, industrial
equipment, and other "old economy" sectors--declined while
the technology-heavy NASDAQ Composite Index rose. The S&P
500, representing something of a compromise between the
other two indexes, drifted irregularly lower for the
first two months of 2000. The Fed fulfilled expectations
by raising interest rates for the fourth time in nine
months on February 2, 2000.
Around the same time, however, the U.S. Treasury,
reacting to recent budget surpluses that have reduced the
government's borrowing needs, announced a buyback program
for a number of its debt securities. The program was
expected to involve repurchasing up to $30 billion in
longer-term Treasury securities by the end of 2000. It
was also stated that issuance of new two-, five-, and 10-
year notes would be reduced, as would issuance of 30-year
bonds. Reacting to the prospect of increased demand and
lower supply of Treasury securities, fixed-income
investors pushed the yield on the 30-year Treasury bond
down sharply.
Although the effect was not immediate, the decline in
bond yields appeared to reassure many stock investors,
prompting the apparent beginnings of a rotation from "new
economy" into "old economy" stocks. The negative effects
of this movement were felt most by marginal technology
stocks with no earnings. Another contributing factor was
the fact that after falling sharply for two months, "old
economy" stocks appeared to be at bargain
levels. Technology shares, on the other hand, had been in
a strong uptrend for over four months and had become
increasingly pricey. Anticipation of rosy first-quarter
earnings reports also undoubtedly contributed to
investors' interest in many of the more established
components of the S&P

500. All of these influences combined to trigger an
explosive rise on March 16 that sent the S&P 500 soaring
over 66 points, while the Dow gained over 500 points.
More gains followed in the last two weeks of March, and
the S&P 500 ended the period within striking distance of
its new all-time intraday high of 1552.87. In spite of
the slackening interest in the more speculative segments
of the technology sector, stalwarts such as Intel, Cisco
Systems, Oracle, Qualcomm, and Sun Microsystems populated
the list of the strongest contributors to the Fund's
returns.
Index funds positioned to benefit
from rapid sector rotation
The fundamentally sound U.S. economy has led to a
steadily rising stock market characterized by frequent
sector rotation. Under all but the most extreme
conditions--the crisis that occurred in the fall of 1998
was one example--managers of actively managed funds have
reacted to changing market conditions, not by taking
money out of the market but by redeploying it in sectors
that seem more appealing. Moreover, these rotations are
occurring more quickly than before--so quickly, in fact,
that it is difficult for those who are not already
positioned to benefit. This was particularly true of the
rally in cyclical shares that occurred in April and May
1999.
A rotational market environment is ideal for index funds,
which, through their broad diversification, are able to
catch strong trends in virtually any sector. Moreover,
index funds do not incur the high transaction expenses
involved in switching back and forth between "hot"
sectors since their portfolios remain relatively stable.

Prudential Stock Index Fund

Investment Adviser's Report

Looking Ahead
The delayed effects of higher interest rates should soon
begin to slow economic growth, allowing the Fed to
stabilize rates for a while. If the Fed can achieve its
goal of slowing the economy without pushing it into
recession, there may even be an opportunity for lowering
rates again. A growing economy with stable or falling
rates would constitute a favorable background for stocks,
and we would expect this to be reflected in higher share
prices. With the bubble in technology perhaps beginning
to burst, the emphasis going forward should be on
traditional measures of value such as price/earnings
ratios. This renewed focus on value could hurt the more
speculative issues, but should benefit those companies
with solid earnings prospects, many of which are included
in the S&P 500.

             Notes to Financial Statements (Unaudited)
      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, one of which is the
Prudential Stock Index Fund (the 'Fund').
      The Fund 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
Company and 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 a 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
manager or subadviser, does not represent fair value, are valued by the
Valuation Committee or Board of Trustees in consultation with the manager or the
subadviser.

       Prudential Index Series Fund     Prudential Stock Index Fund
             Notes to Financial Statements (Unaudited) Cont'd.
      Foreign Currency Translation: The books and records of the Company 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 daily 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 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 portfolio
securities sold during the period. Accordingly, these realized foreign currency
gains (losses) are included in the reported net realized gains (losses) on
investment transactions.
      Net realized losses on foreign currency transactions represent net foreign
exchange gains or losses from holdings of foreign currencies, currency gains or
losses realized between the trade and settlement dates on security transactions,
and the difference between the amounts of dividends, interest and foreign taxes
recorded on the Fund's books and the U.S. dollar equivalent amounts actually
received or paid. Net unrealized currency gains or losses from valuing foreign
currency denominated assets and liabilities (other than investments) at
period-end exchange rates are reflected as a component of net 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.
      Repurchase Agreements:    In connection with transactions in repurchase
agreements, 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
                                                                          31

       Prudential Index Series Fund     Prudential Stock Index Fund
             Notes to Financial Statements (Unaudited) Cont'd.
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 distribution and 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:    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
    32

all of its taxable net income 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.
      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 decrease
accumulated net realized loss on investments by $4,724. 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. 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
Company 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 .65%, 1.40%, 1.40%, .40% and .30% of the average daily net assets for
Class A, Class B, Class C, Class Z and Class I shares, respectively. For the six
months ended March 31, 2000, PIFM subsidized $490,235 of the expenses of the
Fund (1.32%, .10%, .04%, 1.05% and .03% of the average daily net assets of the
Class A, Class B, Class C, Class Z and Class I shares, respectively; $.0625,
$.0079, $.0032, $.0114 and $.0059 per Class A, Class B, Class C, Class Z and
Class I shares, respectively).
      The Company has a distribution agreement with Prudential Investment
Management Services LLC ('PIMS'), which acts as the distributor of the Class A,
Class B, Class C, Class Z and Class I shares of the Company. The Company
compensates PIMS for distributing and servicing the Company's Class A, Class B
and Class C shares, pursuant to plans of distribution, (the 'Class A, B and C
plans'), regardless of
                                                                          33

expenses actually incurred by them. The distribution fees are accrued daily and
payable monthly. No distribution or service fees are paid to PIMS as distributor
for Class Z and Class I shares of the Company.
      Pursuant to the Class A, B and C Plans, the Fund compensates PIMS for
distribution-related activities at an annual rate of up to .30 of 1%, 1% and 1%
of the average daily net assets of the Class A, B and C shares, respectively.
Such expenses under the Plans were .25 of 1%, 1% and 1% of the average daily net
assets of the Class A, B and C shares, respectively, for the six months ended
March 31, 2000.
      PIMS has advised the Fund that it received approximately $179,600 in
front-end sales charges resulting from sales of Class C shares during the six
months ended March 31, 2000. From these fees, PIMS paid such sales charges to
affiliated broker-dealers which in turn paid commissions to salespersons and
incurred other distribution costs.
      PIMS has advised the Fund that for the six months ended March 31, 2000,
they received approximately $11,000 and $4,200 in contingent deferred sales
charges imposed upon certain redemptions by Class B and Class C shareholders,
respectively.
      PIC, PIFM and PIMS are wholly owned subsidiaries of The Prudential
Insurance Company of America.
      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.
Interest on any such borrowings will be at market rates. The purpose of the
agreement is to serve as an alternative source of funding for capital share
redemptions. The Funds pay a commitment fee of .080 of 1% of the unused portion
of the credit facility. The commitment fee is accrued and paid quarterly on a
pro rata basis by the Funds. The expiration date of the SCA is March 9, 2001.
Prior to March 9, 2000, the commitment fee was .065 of 1% of the unused portion
of the credit facility. The Fund did not borrow any amounts pursuant to the SCA
during the six months ended March 31, 2000.
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, 2000,
the Fund incurred fees of approximately $52,000, $14,000, $4,000, $633,000 and
$50 for Class A, Class B, Class C, Class Z and Class I shares, respectively, for
the services of PMFS. As of March 31, 2000, approximately $12,000, $5,300,
$1,100, $115,000 and $10 for Class A, Class B, Class C, Class Z and Class I
shares, respectively, of such fees were due to PMFS. Transfer agent fees and

respectively.
      On March 31, 2000, the Fund held 220 long financial futures contracts on
the S&P 500 Index which expire in December 2000. The cost of such contracts was
$77,426,000. The value of such contracts on March 31, 2000 was $83,341,500,
thereby resulting in an unrealized gain of $5,915,500.
      The cost basis of investments for federal income tax purposes was
$1,676,830,591 and, accordingly, as of March 31, 2000, net unrealized
appreciation for federal income tax purposes was $705,467,851 (gross unrealized

Getting the Most From Your Prudential Mutual Fund

Some mutual fund shareholders won't ever read this--they
don't read annual and semiannual reports. It's quite
understandable. These annual and semiannual reports are
prepared to comply with federal regulations, and are
often written in language that is difficult to
understand. So when most people run into those
particularly daunting sections of these reports, they
don't read them.
We think that's a mistake
At Prudential Mutual Funds, we've made some changes to
our report to make it easier to understand and more
pleasant to read. We hope you'll find it profitable to
spend a few minutes familiarizing yourself with your
investment. Here's what you'll find in the report:
Performance at a Glance
Since an investment's performance is often a
shareholder's primary concern, we present performance
information in two different formats. You'll find it
first on the "Performance at a Glance" page where we
compare the Fund and the comparable average calculated by
Lipper, Inc., a nationally recognized mutual fund rating
agency. We report both the cumulative total returns and
the average annual total returns. The cumulative total
return is the total amount of income and appreciation the
Fund has achieved in various time periods. The average
annual total return is an annualized representation of
the Fund's performance. It gives you an idea of how much
the Fund has earned in an average year for a given time
period. Under the performance box, you'll see legends
that explain the performance information, whether fees
and sales charges have been included in returns, and the
inception dates for the Fund's share classes.
See the performance comparison charts at the back of the
report for more performance information. Please keep in
mind that past performance is not indicative of future
results.

Performance review
The portfolio manager, who invests your money for you,
reports on successful--and not-so-successful--strategies in this
section of your report. Look for recent purchases and
sales here, as well as information about the sectors the
portfolio manager favors, and any changes that are on the
drawing board.
Portfolio of Investments
This is where the report begins to appear technical, but
it's really just a
listing of each security held at the end of the reporting
period, along with valuations and other information.
Please note that sometimes we discuss a security in the
Performance Review that doesn't appear in this listing
because it was sold before the close of the reporting
period.
Statement of Assets and Liabilities
The balance sheet shows the assets (the value of the Fund's holdings),
liabilities (how much the Fund owes), and net assets (the
Fund's equity, or holdings after the Fund pays its debts) as of
the end of the reporting period. It also shows how we
calculate the net asset value per share for each class of
shares. The net asset value is reduced by payment of your
dividend, capital gain, or other distribution, but
remember that the money or new shares are being paid or
issued to you. The net asset value fluctuates daily,
along with the value of every security in the portfolio.
Statement of Operations
This is the income statement, which details income
(mostly interest and
dividends earned) and expenses (including what you pay us
to manage your money). You'll also see capital gains
here--both realized and unrealized.

Statement of Changes in Net Assets
This schedule shows how income and expenses translate into changes
in net assets. The Fund is required to pay out the bulk
of its income to shareholders every year, and this
statement shows you how we do it (through
dividends and distributions) and how that affects the net
assets. This statement also shows how money from
investors flowed into and out of the Fund.
Notes to Financial Statements
This is the kind of technical material that can
intimidate readers, but it does contain useful
information. The Notes provide a brief history and
explanation of your Fund's objectives. In addition, they
outline how Prudential Mutual Funds prices securities.
The Notes also explain who manages and distributes the
Fund's shares and, more importantly, how much they are
paid for doing so. Finally, the Notes explain how many
shares are outstanding and the number issued and redeemed
over the period.
Financial Highlights
This information contains many elements from prior pages,
but on a per-share basis. It is designed to help you understand
how the Fund performed, and to compare this year's performance and
expenses to those of prior years.
Independent Auditor's Report
Once a year, an outside auditor looks over our books and
certifies that the information is fairly presented and
complies with generally accepted accounting principles.
Tax Information
This is information that we report annually about how
much of your total return is taxable. Should you have any
questions, you may want to consult a tax adviser.

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

Getting the Most From Your Prudential Mutual Fund

When you invest through Prudential Mutual Funds, you
receive financial advice from a Prudential Securities
Financial Advisor or Pruco Securities registered
representative. Your advisor or representative can
provide you with the following services:
There's No Reward Without Risk; but Is This Risk Worth
It?
Your financial advisor or registered representative can
help you match the reward you seek with the risk you can
tolerate. Risk can be difficult to gauge--sometimes even
the simplest investments bear surprising risks. The
educated investor knows that markets seldom move in just
one direction. There are times when a market sector or
asset class will lose value or provide little in the way
of total return. Managing your own expectations is easier
with help from someone who understands the markets and
who knows you!
Keeping Up With the Joneses
A financial advisor or registered representative can help
you wade through the numerous available mutual funds to
find the ones that fit your individual investment profile
and risk tolerance. While the newspapers and popular
magazines are full of advice about investing, they are
aimed at generic groups of people or representative
individuals--not at you personally. Your financial advisor
or registered representative will review your investment
objectives with you. This means you can make financial
decisions based on the assets and liabilities in your
current portfolio and your risk tolerance--not just based
on the current investment fad.
Buy Low, Sell High
Buying at the top of a market cycle and selling at the
bottom are among the most common investor mistakes. But
sometimes it's difficult to hold on to an investment when
it's losing value every month. Your financial advisor or
registered representative can answer questions when
you're confused or worried about your investment, and
should remind you that you're investing for the long
haul.
