Letter
To Contract Owners

[PHOTO]


E. Michael Caulfield
President

================================================================================
"We're quite pleased with the return on stocks in the last three years, but we
don't think this divergence from historical norms can continue indefinitely."


Dear Contract Owner:

We are pleased to provide our Annual Report to you on the investment performance
of the Portfolios that underlie your DISCOVERY SELECT-SM- Variable Annuity
contract.

It has been another exceptional year. For the third year in a row (and the first
time in history), stock prices have risen by more than 20%, driven by
unexpectedly high corporate profits and surprisingly low inflation. Bonds also
performed quite well, with total returns averaging just below 10%.

We live in remarkable times. The U.S. economy grew by almost 4.0% in 1997, yet
inflation fell to 1.7%, the lowest since oil prices collapsed 11 years ago.
Unemployment dipped below 5% for the first time since the 1970s. And consumer
confidence was the highest in 28 years. Yet, we live in a global economy. The
economic turmoil, stock market and currency declines in Asia impacted global
markets in the fourth quarter and the economic effects on the world's growth are
not yet clear.

How Did Your Portfolios Perform?

You'll be pleased to know that the DISCOVERY SELECT portfolios delivered returns
similar to those of the broader markets and were consistent with the strategies
around which they were designed. Virtually all of the U.S. stock portfolios
posted double-digit returns, while the bond portfolios finished with very
healthy results.

Some portfolios performed exceptionally well, reaping unusually high historical
returns. Several portfolios even finished the year with returns higher than the
average variable annuity contracts in their respective categories. [They were
the Money Market, Government Income, High Yield Bond, Stock Index, Equity
Income, Prudential Jennison and Small Capitalization Stock Portfolios.]

It's Long-Term Performance That Counts.

Although in this Report we're focusing primarily on one-year performance,
remember that it's long-term performance that counts. Review your Portfolio's
1997 performance, but also be sure to examine its longer-term record as well.
You'll note that over the past three, five and 10 years many of our Portfolios
have delivered excellent performance, both on an absolute basis and in
comparison with funds having similar objectives.



                                       2
<PAGE>

Our goal is to achieve this kind of above-average investment performance over
time. Such consistency is important, because most people buy variable annuity
products to finance long-term goals. However, when you consider how to allocate
either new or existing assets among your available options, we encourage you to
think about your horizon and risk tolerance and to consider future returns
rather than focusing on past performance. Past performance is no guarantee of
future results.

What Goes Up Can Also Go Down.

While discussing the long-term, we think it's crucial to remind Contract Owners
that stocks have offered a 10.7% average annual return over the last 70 years --
about half of what they have given us over the last three years. And since 1980,
corporate revenues have risen 4% a year, while earnings have risen almost twice
as fast and stock prices four times as much.

Can this continue? We're quite pleased with the return on stocks in the last
three years, but we don't think this divergence from historical norms can
continue indefinitely. It's simply the law of averages. We must remember that
with return comes risk -- that stocks can and do go down as well as up. If you
have benefited more than you expected in recent years, then at some point you
will surely benefit less. The only question is: When? Given the very serious
economic crisis in Asia, it could be sooner rather than later.

With this in mind, you may want to evaluate how you allocate your contract funds
among the available investment options. While stocks ought to remain the
investment of choice for most investors looking for long-term wealth
accumulation, now might be a good time to consider diversifying a portion of
your holdings. If you wish to, contact your Prudential Securities Financial
Advisor/Pruco Securities Registered Representative for assistance in structuring
a program to help meet your needs.

All of us at Prudential thank you for your business and look forward to helping
you plan for your future financial security.

Important Note

The rates of return quoted on the following pages reflect the deduction of
investment management fees and investment-related expenses, but not product
charges. They reflect the reinvestment of dividend and capital gains
distributions. They are not an estimate or a guarantee of future performance.

Contract unit values increase or decrease based on the performance of the
Portfolio and, when redeemed, may be worth more or less than their original
cost. Changes in contract values depend not only on the investment performance
of the Portfolio but also on the insurance and administrative charges,
applicable sales charges, and the mortality and expense risk charge applicable
under the contract. These contract charges effectively reduce the dollar amount
of any net gains and increase the dollar amount of any net losses.

Your Prudential Securities Financial Advisor/Pruco Securities Registered
Representative can provide you with actual rates of return for your type of
variable life insurance or annuity contract and show you a personalized
illustration of how insurance charges affect the returns you experience.

GREAT NEWS
DISCOVERY SELECT-SM-


================================================================================
Look for your Enhanced Death Benefit information package and election form in
your mailbox soon.


Now Offering Increased Death Benefit Protection at No Additional Cost.

DISCOVERY SELECT now offers you an Enhanced Guaranteed Minimum Death Benefit.(1)
This new death benefit was designed with your needs in mind and is an example of
Prudential's ongoing commitment to your retirement goals. The new death benefit
includes the following features:

o    Death benefit protection can increase at each anniversary date, as opposed
     to every three years in your current death benefit.

o    Death benefit protection in both rising and declining markets. Your
     beneficiaries are guaranteed to receive the greater of these three values:

     1.   Current Account Value.

     2.   Annual Contract Value Step-Up. Each year, your death benefit can
          step-up to your current account value, enabling you to lock in your
          investment gains for beneficiaries in a rising market. (This value
          will be adjusted for additional purchase payments and reduced
          proportionally by the effect of withdrawals.)

     3.   5% Annual Increase. This feature even increases your protection in
          declining markets, by compounding the total of all your purchase
          payments at an effective annual rate of return of 5%, subject to a
          200% cap.(2) (Not available in New York. This value will also be
          adjusted for additional purchase payments and reduced proportionally
          by the effect of withdrawals.)

To Choose the New Death Benefit: Sign and Return the Election Form.

DISCOVERY SELECT contract owners with annuitants under age 80 will be given the
option of electing this new death benefit or keeping the current contract's
death benefit.

If eligible, you will receive a special mailing shortly that fully explains this
new death benefit enhancement and how it differs from your current death
benefit. If you decide the new death benefit is right for you, simply sign and
date the Election Form that will be sent to you in the special mailing and
return it within 90 days to the Prudential Annuity Service Center. A postage
paid reply envelope will be provided.

Keep in mind that the new death benefit may not be appropriate for everyone,
especially if you are nearing age 80. If you have any questions, please contact
your Prudential professional.

Two DISCOVERY SELECT-SM- Portfolios Reclassified

The Prudential Investments Asset Allocation Program was designed to help you
find your right mix of investments within your DISCOVERY SELECT Variable
Annuity. Each quarter, our research team reviews the underlying portfolios in
DISCOVERY SELECT to ensure that they continue to meet a strict set of criteria,
including above average long-term performance, asset class consistency,
consistency of their investment philosophy, and a stable management team.

After a recent review, Prudential Investments has reclassified two of the
Small/Mid Cap portfolios into the Large Cap Asset Class.

o    The MFS Research Series, previously a Small/Mid Cap Growth portfolio, has
     been reclassified to a Large Cap Growth portfolio.

o    The AIM V.I. Value Fund, previously a Small/Mid Cap Value portfolio, has
     been reclassified to a Large Cap Value portfolio.

In the Small/Mid Cap Growth category, DISCOVERY SELECT still offers a choice of
the MFS Emerging Growth Series and the Warburg Pincus Post-Venture Capital
Portfolio. In the Small/Mid Cap Value category, DISCOVERY SELECT offers the OCC
Accumulation Trust Small Cap Portfolio.

A complete listing of all of Discovery Select's portfolios, and their
corresponding asset categories, appears on page 6. For more information, or to
complete a new Asset Allocation Questionnaire, contact your Prudential
Securities Financial Advisor/Pruco Securities Registered Representative.

================================================================================

It's a good idea to complete a new questionnaire each year to make sure your
asset allocation reflects any changes in your investment needs, goals, and time
horizon.


1    Certain restrictions may apply, particularly for contracts with annuitants
     age 80 or over. See the prospectus supplement for full details. The
     Guaranteed Minimum Death Benefit may not be available in all states.

2    Not available in New York and may not be available in other states. The 5%
     Annual Increase is limited to a maximum cap equal to two times each
     purchase payment and is reduced proportionally by the effect of
     withdrawals. Once the cap is reached, approximately 14 years after the
     initial purchase payment, the benefit will only increase with additional
     purchase payments, proportionally reduced by the effect of withdrawals.

This chart compares the 12-month return as of 12/31/97 for various categories of
investments with the average annual total return over 20 years for the same
investment. As you can see, stock and bond market returns can vary considerably
from year to year. Unlike stocks, bonds generally offer a fixed rate of return
and principal if held to maturity. An investment's past performance should never
be used to predict future results. There are different risks associated with
each investment sector, which should be carefully considered before investing.

     Stanley Capital International World Index. U.S. stocks as measured by the
     S&P 500 Index.

U.S. Stocks

Nothing Short of Spectacular.

U.S. stocks rose more than 20% for the third straight year for the first time in
history -- measured by either the Dow Jones Industrial Average (the "Dow Jones")
or the Standard & Poor's 500 Composite Stock Price Index (the "S&P 500").

Unexpectedly high corporate profits and exceptionally low inflation, plus strong
economic growth and the lowest unemployment rate and highest consumer confidence
in 28 years, all combined to drive emotions in the stock market to euphoric
levels.

The numbers were impressive, considering that stocks have gained only 10.7% on
average over the last 70 years. In 1997, the S&P 500 gained 33%, after rising
23% in 1996 and 37% in 1995.

Only in October did a reality check set in, when the market fell briefly by 10%
in what market professionals called a correction. But stock prices quickly
rebounded, and many major indexes moved on to new highs.

Still, the momentum of the market had clearly slowed by year-end as investors
became increasingly concerned about the economic crisis in Asia and how severely
it might affect corporate earnings in 1998.

Large, Value Stocks Dominated.

Large company stocks continued to lead the market higher in 1997. For example,
the small company-oriented Russell 2000 Index rose 22.4% during calendar year
1997, nearly 12 percentage points behind the S&P 500.

Financial stocks rose 49% in 1997 as consolidation continued to sweep the
industry and long-term interest rates fell to their lowest levels since 1993.
Banks and stock brokerage firms are continuing to achieve economies of scale
through acquisitions.

investors sought companies with safe earnings streams. Interestingly, for the
year, utilities beat the S&P 500.

Bonds

Inflation Fell Sharply, Pushing Prices Higher.

Nineteen ninety-seven was a very good year for bonds, as inflation fell below 2%
for the first time in 11 years and long-term interest rates dipped to their
lowest level since 1993.

Bonds returned a healthy 9.65% for the year as measured by the Lehman Brothers
Aggregate Index, led by high yield bonds in the United States, which returned
12.76%.

A financial crisis in Asia late in the year set off a major rally in the U.S.
Treasury market, where the 30-year bond returned more than 15% in 1997 as the
yield fell by nearly three-quarters of a percentage point to 5.92% at year-end.
Worldwide, investors bought Treasurys after Southeast Asian currencies collapsed
under the weight of excesses in the financial sector and overinvestment in real
estate and infrastructure.

Fundamentally, economic conditions were nearly ideal for bond investors, as
inflation seemed to be slowly fading away. Prices at the wholesale level
actually fell by 1.7% as measured by the government's Producer Price Index, but
at the retail level prices continued to rise, even if only by 1.7%, as measured
by the Consumer Price Index. Still, that was the lowest increase in 11 years,
and nearly half of 1996's rate.

As interest rates fell, home mortgage refinancings rose, with 30-year rates
falling below 7%. Others, including noted investor Warren Buffett, were reported
to be investing in bonds, and cash flows into bond mutual funds quadrupled in
1997.

High yield corporate bonds led all other sectors of the U.S. bond market in 1997
as corporate profits climbed unexpectedly higher while economic growth surged.
The lowest-rated bonds performed the best. Nineteen ninety-seven was another
record-breaking year for newly issued high yield bonds. These bonds were in such
demand in 1997 that the interest rate premium they commanded over U.S. Treasurys
reached all-time lows in October.

Foreign Stocks

A Plunge in the Pacific.

Asian stock markets plunged in 1997 as Southeast Asian currencies collapsed
under the weight of excesses in the financial sector and overinvestment in real
estate and infrastructure. Currencies in some countries fell by nearly 50%
against the U.S. dollar. Credit and cash became scarce and economies slowed. The
financial crisis eventually reached Japan, helping to halt a nascent economic
recovery.

The Morgan Stanley Capital International Pacific Index fell 25% during the year
as stocks in Thailand dropped 77%, Indonesia 74% and Malaysia 68%, all in U.S.
dollar terms. Even older, larger, more developed Pacific Basin countries did not
escape unscathed. Economic malaise continued to linger in Japan, where stocks
dropped almost 24% in U.S. dollars for the year.

European Stocks Performed Well.

In Europe, stocks performed quite well during the year, rising over 24% for
U.S.-based investors despite a strong dollar. Developing countries were strong,
such as Portugal, up 48%, and older, more established stock exchanges also
posted excellent returns, with Switzerland rising 45%, Italy up 36% and Germany
ahead 25%, all measured by Morgan Stanley in U.S. dollars.

European stocks benefited as the movement toward a European economic union
fostered less government borrowing and thus lower interest rates, which
stimulated the sluggish economies of Germany and France and led to rapid growth
in smaller countries on the periphery, such as Ireland.

In addition, corporate restructuring continued to improve productivity, driving
double-digit earnings gains. Europe has also been the region least affected by
economic turmoil in Asia, its stock prices are less expensive than those in the
United States, and Europe is earlier in its economic growth cycle than the
United States, which is now in its seventh year of economic recovery.

1998
Investment Advisor's Outlook

The Economy

Expect Slower Growth.

Our economists at Prudential forecast slower economic growth plus a slight
increase in inflation and unemployment in 1998. They are looking for the U.S.
economy to grow slower than 2%, less than half as fast as it grew in 1997. We
believe inflation will remain acceptable, but that the Consumer Price Index may
rise as much as 2.2%, somewhat faster than 1997's 1.7%. As demand for U.S.
exports slows in Asia, unemployment should rise toward 5.5%, up from December's
4.7%.

Prudential's economists expect short-term interest rates to fall by half a
percentage point in 1998, and long-term rates to end the year close to where
they began -- at around 6%. Our economists forecast that the Federal Reserve
Bank will lower interest rates by a quarter of a percentage point in the spring
and another quarter point in the summer, bringing the federal funds rate (or
overnight bank lending rate) down to 5%. As of this writing in early January,
interest rates on government bonds maturing in 10 years or less were priced to
yield below 5.50%, the official overnight lending rate.

U.S. Stocks

We're Looking for an Average Year.

We said it last year. And the year before. Each year we've said that surely the
U.S. stock market would not rise by 20% again in the following year. But the
market has done just that now for three years in a row -- for the first time in
history. Can this remarkable performance continue? Over the last 70 years, the
historical average return for stocks is only about 10.7%. This year, more than
ever, we expect that stocks will turn in a performance much closer to average.

We're cautious, conservative investors, so we build our portfolios one stock at
a time. This year, with continued economic growth and modest inflation expected,
we believe that earnings will be the key force driving stock market performance.
We'll be looking even more closely than usual at a company's ability to meet its
corporate earnings expectations, because investors have become very unforgiving
of even the slightest shortfall in earnings.


                                       12
<PAGE>

In the United States, we are particularly interested in smaller company stocks,
because we believe they are very attractively priced, considering their earnings
expectations. These stocks have trailed large company stocks for several years
now, but small company stocks have historically fared better than larger company
stocks.

U.S. Bonds

Off to a Great Start.

The U.S. bond market performed well in the early days of 1998 as the interest
rates on the 30-year U.S. Treasury fell to their lowest level since the
government first started to sell them regularly in 1977.

Despite the rally, interest rates remain quite favorable when adjusted for
inflation. So if we experience slower economic growth and continued low
inflation, bond holders may yet enjoy more price appreciation in addition to
their coupon income.

We are firm believers in corporate bonds, which we expect will continue to
perform well as the economy grows and the effects of the Asian economic crisis
are more fully understood in the months ahead. Similarly, we expect certain
emerging markets bonds that have been badly beaten down by this crisis to return
to more realistic price levels.

Foreign Stocks

Watching Closely.

Overseas, we are watching the Asian situation closely, but believe it may be too
early to make a substantial commitment there. We are being selective, choosing
stocks rather than countries. In Europe, we expect strong economies and stock
markets in 1998 as companies there continue to restructure.

================================================================================
A Reality Check.

Stock prices in general have nearly doubled in the last three years. We're quite
pleased with the unusually high returns that stocks have provided for our
Contract Owners over the past few years and we are certain that you are, too.
Those types of returns bring you closer to your goals of financial security
faster than you might have expected.

Since 1927, the U.S. stock market's average return has been 10.7%, as measured
by the S&P 500. Yet, in recent years returns have been much higher, as the chart
below shows.

Prudential
Money Market Portfolio

Performance Summary.

Emphasizing a combination of very short-term and longer term money market
securities during most of the year enabled your Portfolio to return 5.41%, which
beat the 5.13% gain of the average money market fund tracked by Lipper
Analytical Services. On Dec. 31, your Portfolio's seven-day yield was 5.61%, up
from 5.36% on June 30.

We also took advantage of higher yields on one- to three-month money market
securities toward the end of the year when the deepening Asian economic crisis
pushed up short-term borrowing costs.

An investment in the Money Market Portfolio is neither insured nor guaranteed by
the U.S. government. There is no guarantee that the Portfolio will be able to
maintain a stable share value of $10.00.

Performance Review.

A Buying Opportunity. The U.S. economy raced into 1997, powered by a strong job
market and increased spending by consumers. By mid-February, investors began
driving up yields on money market securities, because they correctly anticipated
that U.S. central bankers would soon increase the federal funds rate to prevent
vigorous economic growth from kindling higher inflation. Of course, this market
trend provided excellent buying opportunities. We purchased one-year corporate
obligations for their higher yields. Concurrently, investing in one-month money
market securities enabled us to have cash on hand to buy higher-yielding
securities that became available after the federal funds rate rose a quarter
percentage point, to 5.50%, on March 25.

Strategy Session.

The Long and Short of It.

For the first eight months of the year, we kept your Portfolio's weighted
average maturity (WAM) generally longer than that of comparable funds by taking
advantage of opportunities to lock in higher yields. Indeed, the one-year London
Interbank Offered Rate or LIBOR, a popular global barometer of short-term
interest rates, climbed to its highest level of the year at 6.44% on April 28
and remained comfortably above 6% during much of the summer. Emphasizing a
mixture of one-month and one-year money market securities (a barbell strategy)
insured that we always had money available to buy attractively priced securities
when yields spiked higher on concern there could soon be another change in
monetary policy.

Some investors looked at subdued inflation, concluding that the Federal Reserve
would leave monetary policy unchanged. Still, there were sound reasons to expect
a second federal funds rate increase, such as continued strong U.S. economic
growth. By late October, we shortened our WAM just in case U.S. central bankers
decided to move again in December and to be prepared to exploit an anticipated
rise in yields fueled by year-end market pressures. We took advantage of higher
yields that resulted from the economic upheaval in Asia. We purchased money
market securities maturing in one to three months, which slightly lengthened our
WAM in late December.

- --------------------------------------------------------------------------------
Outlook

PORTFOLIO MANAGER
Manolita Brasil

Fed on Hold, for Now.

"I expect the Federal Reserve to leave monetary policy unchanged in the near
future because inflation will likely remain subdued due to increased competition
from attractively priced Asian imports. But I don't expect the pace of economic
activity to slow dramatically, since any decline in our exports to Asian
countries will probably have a limited impact on our gross national output.
Furthermore, I strongly doubt that U.S. economic growth will slow enough to
cause the Federal Reserve to cut the federal funds rate as some Wall Street
analysts have recently suggested. With that in mind, I think investors have
pushed yields on money market securities too low. So I am wary of purchasing
certain short-term securities that are clearly too expensive. Sooner rather than
later, I expect to see yields edging higher as more market participants realize
the Federal Reserve is not about to ease monetary policy with the unemployment
rate below 5 percent."

Diversified Bond Portfolio

Performance Summary.

Economic upheaval in Asia sparked a sell-off in stocks and emerging market debt
securities late in the year, but demand increased for U.S. Treasurys and
government agency bonds, which investors viewed as a safe haven from overseas
turmoil. Your Portfolio's total return of 8.57% lagged the 10.01% gain of the
Lipper (VIP) Corporate BBB Average because of its stake in emerging market bonds
of countries such as Russia and Thailand. Our foreign holdings, denominated in
U.S. dollars, are the same type of bonds that have helped your Portfolio achieve
above benchmark returns in other time periods.

By contrast, a sizable investment in bonds of U.S. media/cable and financial
services firms strengthened your Portfolio's performance as a wave of
consolidation and fresh investments improved the financial health of several
companies in both industries.

The Portfolio may invest in foreign securities. Foreign investments are subject
to the risk of currency fluctuation and the impact of social, political and
economic change.

Performance Review.

Asian Whirlwind. The federal funds rate was raised by a quarter percentage
point, to 5.50%, in March to prevent the economy from racing ahead and
increasing inflation, which would erode the value of a bond's fixed interest and
principal payments. By mid-April, however, investors began to drive bond prices
higher (and yields lower), because inflationary pressures remained unusually
subdued.

The bond rally stayed on track during the summer, but an economic whirlwind out
of Asia shook global financial markets in October. Prices of U.S. Treasurys and
government agency debt securities surged, while emerging market bond prices
tumbled as investors feared other developing nations might suffer the same fate
as countries like Thailand and Indonesia.




                                       16
<PAGE>

Strategy Session.

Trouble on Distant Shores. Our holdings in emerging markets bonds of Latin
American and Asian countries initially aided your Portfolio's performance.
Reduced inflation estimates for some Latin American nations encouraged
investors, as did plans for tax reform legislation in Russia. Nevertheless,
negative developments in countries such as Indonesia and Thailand took center
stage, igniting a broad sell-off in emerging markets bonds.

The deepening economic crisis in Asia sent cash flowing into U.S. government
securities as investors sold stocks and emerging markets bonds. Asian economic
problems had been brewing for some time, but the full extent of the crisis came
to light only in October, when investors feared that countries such as South
Korea could have been teetering on the brink of economic collapse, partly
because of imprudent lending practices of Asian banks.

On Solid Ground at Home. While some U.S. corporate bond prices declined, gains
were recorded in other sectors such as financial services and media/cable. For
example, Salomon Inc. bonds rallied following the announcement that it would
soon be acquired by financial services giant Travelers Group, and our holdings
in Time Warner and Tele-Communications Inc., also posted impressive gains as
their financial positions improved.

- --------------------------------------------------------------------------------
Outlook

PORTFOLIO MANAGER
Barbara Kenworthy

Bond Yields Could Drift Lower.

"We expect prices on U.S. Treasury securities to trade in a fairly tight range,
with the yield on the 30-year benchmark bond varying between 5.50% and 6.50%.
Continued low inflation and a possible government surplus should support bond
prices. In addition, competition from cheaper Asian imports will probably help
keep inflation in check in the United States. Bond yields could drift still
lower, but it's quite possible that most of the good news has already been
factored into prices of U.S. Treasurys.

"Last year's sell-off in emerging markets bonds seems to have been too severe.
We are seeing new buying interest in 1998 as investors hope for economic
stability as a result of reforms initiated in some countries. Meanwhile,
issuance of new U.S. corporate bonds has increased as companies rush to take
advantage of lower borrowing costs. Investors, however, are hunting for value in
the market, and generally like what they see in corporate profits. The
incremental yield over Treasurys provided by corporate bonds should attract
investors."

Prudential
High Yield Bond Portfolio

Performance Summary.

Your Portfolio's total return of 13.78% exceeded the 13.41% gain on the average
high yield bond fund tracked by Lipper Analytical Services, because
consolidation and improving business conditions in the cable television and
communications industries bolstered the prices of several of our holdings.

Your Portfolio performed well because it had limited exposure to emerging
markets bonds, which declined late in the year as investors grew increasingly
concerned about the possibility of an economic upheaval in Asia.

The Portfolio may invest in foreign securities. Foreign investments are subject
to the risk of currency fluctuation and the impact of social, political and
economic change.

Investment Goal

High total return.

Types of Investments

Primarily non-investment grade bonds. These bonds have speculative
characteristics and are subject to greater credit and market risk than
higher-quality securities.

Investment Style

Concentrates primarily on junk bonds that appear to offer an attractive
combination of high current income and attractive total return.

Performance Review.

Above the Fray. High yield or junk bond prices fell early in the year as
investors correctly anticipated a federal funds rate increase in March to slow
U.S. economic growth and prevent higher inflation, which erodes the value of a
bond's fixed interest and principal payments. But because inflation remained
surprisingly subdued, bonds, including junk bonds, began to rally in the spring.
Solid economic growth combined with banks' willingness to lend money allowed the
default rate of high yield bond companies to stay below historic averages,
reassuring investors.

In the autumn, emerging markets bonds tumbled as investors feared other
developing countries might suffer the same fate as Southeast Asian nations. Your
Portfolio remained above the fray partly because it held few emerging markets
bonds.

Strategy Session.

A Banner Year. By several measures, junk bonds enjoyed a good year in 1997.
Returns on high yield bonds led all other sectors of the U.S. bond market as
brisk economic growth fed corporate profits. Investors, hungry for higher
yields, bought a record $138 billion of newly issued junk bonds during the
reporting period. Demand was so strong that the difference between yields of
junk bonds and Treasury securities declined to an all-time low in October,
indicating that investors were willing to accept a smaller reward for taking a
chance on high yield bonds.

We Got the Picture. We focused on the cable television industry, where
Microsoft's $1 billion investment in Comcast helped to enhance the value of
cable television bonds. Similarly, Cablevision Systems bonds gained after an
announcement that Tele-Communications and News Corp. planned to pay $850 million
for a 40% stake in the sports television business of Cablevision Systems to
create a national chain of cable television sports channels. We held bonds that
benefited from both of these developments.

Among satellite television companies, Echostar Communications had a prosperous
year, even though News Corp. backed away from a proposed merger with the firm.
Since the merger agreement fell through, the nation's fastest-growing provider
of satellite television has raised more than $690 million in debt and stock to
help finance its plans. Furthermore, Echostar passed the 1 million subscriber
level after adding approximately 700,000 new subscribers in 1997, its first full
year of operation.

Outlook

PORTFOLIO MANAGER
George W. Edwards, CFA

Cutting Here, Adding There.

"We still like the communications sector of the high yield bond market, because
of its extremely positive business fundamentals, including a regulatory
environment that supports new competition and growing demand for
telecommunications services that more than offsets lower prices in the industry.
However, we are aware of the possibility that a deluge of new bond issues in
that industry could weaken prices of outstanding bonds.

"We are also carefully monitoring the Portfolio just in case economic growth
slows and causes the credit quality of our bonds to deteriorate."

Prudential
Stock Index Portfolio

Performance Summary.

Your Portfolio finished 1997 with a return of 32.83%, culminating an
unprecedented three-year run of above-20% returns.

Stock prices recovered from each of three significant drops during the year: one
in the spring sparked by rising interest rates and two in August and October
driven primarily by concern that today's high corporate earnings could not be
sustained. But the U.S. economy proved surprisingly resilient and continued to
grow at a moderate rate, with extraordinarily low inflation and unemployment.
Nonetheless, we think investors should not expect a continuation of the
exceptional returns of the past three years.

Standard & Poor's neither sponsors nor endorses the Stock Index Portfolio.
Investors cannot directly invest in any index, including the S&P 500.

Performance Review.

The Stock Index Portfolio attempts to hold all 500 stocks included in the S&P
500 Index and attempts to duplicate its performance. Portfolio Manager John W.
Moschberger manages the Portfolio by investing funds received while trying to
minimize commissions and transaction costs.

Financial Services the Clear Leader. While technology stocks had an erratic
year, financial stocks played the tortoise to their hare, finishing the year
with a 49% gain. Savings and loans and integrated financial services/brokerages
led the pack. Ahmanson and Great West both doubled in price while Merrill Lynch,
Morgan Stanley Dean Witter, and Travelers each gained 80%. The Finance sector --
which comprises about 17% of the S&P 500 -- rose relatively steadily throughout
the year.

The consumer sectors, both cyclicals and growth/staple stocks, produced almost a
37% return. Together they represent more than a third of the S&P 500 value.
Utilities finished the year in the same neighborhood -- a 36% gain -- after
accelerating toward the end of the year when investors sought companies that
would be relatively unaffected by events in Asia.

Industrials and Energy Trail. Industrials were the trailing sector, although in
this exceptional year even the low end represented a 22% gain. The energy
sector, only 8% of the S&P 500, rose 26% this year.

Technology Erratic. Technology stocks, the sometime high-flyers, had a very
volatile year. At times they led the market. However, the weak aerospace/
defense industry and a fear of the impact of economic turmoil in Asia that
dominated the fourth quarter combined to produce a 27% return for the year that
was in the middle of the pack.

PORTFOLIO MANAGER
John W. Moschberger

Stocks, Best Long-Term.

"Although stocks have historically provided the best long-term return of the
major asset classes, their history also has included both up and down years.
This is the first three-year run with returns above 20%. Good long-term
investing practice should be based on realistic expectations, neither
excessively high nor too fearful to ride out the inevitable rough spots."

Prudential
Equity Income Portfolio

Performance Summary.

Over the past year, your Portfolio gained 36.61%, seven percentage points above
the Lipper (VIP) Equity Income Average of 29.47%.

The Equity Income Portfolio was the #1 fund of all Lipper Equity Income Variable
Life and Variable Annuity contracts for both the one-year (1 out of 22 funds)
and five-year periods (1 out of 5 funds)(2).

Your Portfolio had an outstanding year in 1997, outrunning a strongly rising
Standard & Poor's 500 Index in a year in which most managed portfolios trailed
it. Our value investing style may mean waiting for the average investor to
appreciate what we've bought, but the reward for patience can be substantial
when market prices catch up. This year, several elements of our investment
strategy worked exceptionally well.

The Portfolio may invest in foreign securities. Foreign investments are subject
to the risk of currency fluctuation and the impact of social, political and
economic change.

(*)  Lipper provides data on a monthly basis, so for comparative purposes the
     Lipper Average and Index since inception returns reflect the Portfolio's
     closest calendar month-end performance of 2/29/88.

(1)  Past performance is not predictive of future performance. Portfolio
     performance is net of investment fees and fund expenses but not product
     charges.

(2)  The Lipper Variable Insurance Products (VIP) Equity Income Average is
     calculated by Lipper Analytical Services, Inc., and reflects the investment
     return of certain portfolios underlying variable life and annuity products.
     These returns and rankings are net of investment fees and fund expenses but
     not product charges.

(3)  The S&P 500 is a capital-weighted index representing the aggregate market
     value of the common equity of 500 stocks primarily traded on the New York
     Stock Exchange. The S&P 500 is an unmanaged index that includes the
     reinvestment of all dividends but does not reflect the payment of
     transaction costs and advisory fees associated with an investment in the
     Portfolio. The securities that comprise the S&P 500 may differ
     substantially from the securities in the Portfolio. The S&P 500 is not the
     only index that may be used to characterize performance of this Portfolio,
     and other indexes may portray different comparative performance.

Investment Goal

Current income and capital appreciation.

Types of Investments

Primarily stocks and convertible securities with prospects for income returns
above those of the S&P 500.(3)

Investment Style

The Portfolio uses a "value" investment approach to companies that are
attractively priced relative to book value, earnings, discretionary cash flow,
sales and other measures of value.

Performance Review.

Security Brokerages Score Again. We bought brokerage firm stocks when many
investors expected the stock market to lose steam and brokers' earnings to
suffer. We had relatively large investments in Lehman Brothers (up 64%), Bear
Stearns (up 82%), Paine Webber (up 87%) and Salomon (up 79% before being bought
by The Travelers Group).

We Had the Right Energy Firms. Our energy stocks were focused on oil services
and some integrated producers and they made a substantial contribution to our
returns.

Metals Didn't Hold Up. Although many of our industrial stocks performed well,
the sector as a whole was dragged down by our metals companies, including
USX-Steel and several aluminum companies.



                                       22

Strategy Session.

The Case for Industrials. For some time, we have felt that margins were being
squeezed at the consumer end of the production chain and there was more room for
earnings growth among the industrials. Some of our industrials -- such as
airlines, chemicals and electrical equipment manufacturers -- have performed
well this year. But overall the sector has suffered by investors' tendency to
move where earnings have been relatively predictable in light of events in Asia.
Some of the economically sensitive stocks we like have become quite inexpensive
and we have bought more. Overall, industrials are now about a quarter of our
Portfolio.

Financials Are Strong. We believe that the real estate firms we hold are just
beginning a long process of introducing a more liquid and better managed
structure to U.S. real estate ownership. Their earnings are also relatively
buffered against an economic slowdown. We expect more gains from them.

The securities industry is still in the midst of a consolidation. This year, The
Travelers Group bought one of our holdings, Salomon, and we benefited. Such
purchases increase the value of the remaining targets. Our largest holding is
Lehman Brothers.

- --------------------------------------------------------------------------------
Outlook

PORTFOLIO MANAGER
Warren E. Spitz

Securities Firms Attractively Priced.

"We are value investors, which means that we buy stocks that are inexpensive
considering their projected earnings. For some time we've liked industrials.
Their earnings are sensitive to the rate of economic growth and many investors
refused to believe that the U.S. economy could continue to grow for so long.
This fear of an economic slowdown grew acute at the end of 1997, bringing the
prices of some industrial firms to exceptionally attractive levels. We stocked
up while they were bargains. We are not trying to predict the future. The prices
we paid were very low for the earnings these firms already are making. We expect
them to provide a satisfactory return compared with other companies even in an
economic slowdown. Their potential for price appreciation should their earnings
hold or rise, however, is considerable."

Prudential
Equity Portfolio

Performance Summary.

Your Portfolio returned 24.66% in 1997, close behind the Lipper (VIP) Growth
Average of 25.36% for the period. This was the third successive year of gains
above 20%.

While your Portfolio participated in this year's stock market gains, it was held
back by its large cash holding. In an investing climate not friendly to your
Portfolio's value investing style, its return was close to the average because
it had a strong focus on financial stocks that performed very well in 1997.

The Portfolio may invest in foreign securities. Foreign investments are subject
to the risk of currency fluctuation and the impact of social, political and
economic change.

Investment Goal

Capital appreciation.

Types of Investments

Primarily stocks of major, established companies.

Investment Style

This Portfolio uses a "deep value" investment approach to invest in stocks
believed to be temporarily undervalued relative to the companies' sales,
earnings, book value and cash flow.

Performance Review.

Cash Again Held Us Back. By far the greatest drag on your Port-folio's
performance was its large cash holding -- about 25% through most of 1997. There
was a scarcity of inexpensive stocks for much of the year, and the average stock
was selling for a very high price considering its potential earnings growth. In
this context, the cash is both a buffer against a market decline and a reserve
for rapid action should better investment opportunities appear. In the fourth
quarter, when many investors feared that events in Asia would slow the U.S.
economy, more stocks were driven to bargain prices compared with the average
stock. We reduced our cash holdings to about 17% at December 31.

Financial Services Pushed Us On. We had a focus on financial service companies.
The strong stock market and consolidation in the industry both buoyed stock
prices.

Strategy Session.

We Still Like Financial Companies. We had a focus on financial companies, but
their performance in 1997 was mixed. Our investment banks/securities brokers and
our savings and loans performed very well in 1997. Our large, money center banks
- -- BankAmerica, Chase Manhattan and J. P. Morgan, kept up with the strongly
rising market despite a turn against them in the fourth quarter when turmoil in
Asia made investors uncertain about their future earnings. We believe that when
the uncertainty is resolved their stocks should resume their growth, because
their core businesses are sound.

Health care has been beaten down. We look for companies with excellent
businesses in the long term, but ones whose stocks are inexpensive because
investors are reacting to short-term problems. Right now, HMOs are in trouble
because competition and government reimbursement pressure have capped prices,
while costs are rising. The troubles here are industry wide, not poor management
of any one company. It's in no one's interest to allow the industry as a whole
to fail, so we expect these companies to have more pricing power in 1998.
Currently, they are priced as if they didn't have the tremendous growth
potential that they have.

Paper Makers Have Bottomed. For some time now, paper companies have been good
value. Paper prices and company earnings had begun to rebound until the Asian
economic crisis set them back. Asia accounts for a third of world paper
consumption. Nonetheless, the industry is restructuring and paper demand will
grow faster than new capacity. We think we've seen the bottom of their earnings
cycle, and stock prices still are very low. The industry provides one of the
better value opportunities available.

- --------------------------------------------------------------------------------
Outlook

PORTFOLIO MANAGER
Thomas R. Jackson

There Are More Values Now.

"The uncertainty in Asia has raised questions about the rate of economic growth
in the United States. There is pressure on the stocks of companies whose
earnings vary with economic growth (cyclicals). Investors have been moving
toward industries with more predictable earnings growth. This means there are
more value opportunities in the cyclical industries than there had been -- so
our cash holdings are down."

Performance Review.

Drugs for Financial Health. Several of the stocks we owned rose between 70% and
100% over the course of 1997, including Pfizer, Eli Lilly and Bristol-Myers
Squibb.

Financials Pull Ahead. Our non-bank financial service stocks contributed
substantially to our return, particularly MGIC Investment and UNUM and
brokerages such as Charles Schwab and Morgan Stanley, Dean Witter, Discover.

Technology Was Mixed. The technology sector -- our largest sector -- had an up
and down year. Stocks that contributed strongly to our performance included Dell
and Compaq in computer manufacturing, SAP and Microsoft in software, and Cisco
Systems in networking. Our holdings in 3Com and Ascend Communications detracted
from our performance.

Strategy Session.

A Good Environment for Financials. A strong stock market means good business for
brokerage firms. Consolidation of financial services also makes these firms
attractive. In addition, when interest rates are low or falling, bank stocks
historically have risen. Their business grows because borrowing is cheaper. Our
ten largest holdings include companies in different industries in the
top-performing financial sector: banks (Chase Manhattan), brokerages (Morgan
Stanley, Dean Witter, Discover) and savings and loans (Washington Mutual).

Technology -- Feast or Famine? Technology is our largest sector, although we are
at the low end of our normal range of holdings. These stocks suffered in the
fourth quarter as a result of investor uncertainty about the implications of the
currency crisis and potential economic slowdown in Asia. We expect technology
stocks to recover when investors look at earnings prospects more calmly. Compaq
Computer and Cisco Systems are among our largest holdings and also among the
largest contributors to our 1997 return. We expect Hewlett- Packard's growth to
accelerate when it introduces its next generation of servers and printer
technology.

Drugs -- Lifesavers. We believe that the pressure for cost containment in health
care works in favor of the drug industry. Although many people think of drugs as
expensive, they are much cheaper than alternative forms of treatment and they
often can obviate more expensive care. Pharmaceuticals are our largest industry
focus and the broader health care sector was our performance leader in 1997.

- --------------------------------------------------------------------------------
Outlook

PORTFOLIO MANAGER
David T. Poiesz

Returns Look Good.

"I want to own stocks of companies that will produce a portfolio that can
increase earnings about 20% every year. We use a 12 to 18 month time horizon
when evaluating stocks. We like to find companies where an earnings
disappointment or short-term controversy has knocked down the share price or
where business is improving and not yet fully recognized. Then we get a bargain.
We focus on the fundamentals of the business and try not to be misled by
earnings setbacks that are only temporary.

"We think our retailers have considerable potential. For example, we own Sears
Roebuck and Kohl's Department stores. The latter is a seven-state chain of
retailers oriented to mid-priced apparel. Its stores are friendly and efficient
and we see them expanding nationwide."

Prudential
Global Portfolio

Performance Summary.

Your Portfolio returned 6.98% in 1997, trailing the 13.24% gain of the Lipper
(VIP) Global Average.

In 1997, the strongest stock market in the world was the U.S. market, and we
were underrepresented there, because we thought U.S. stocks were expensive. A
midyear halt to the Japanese economic recovery also hurt our return. So did the
economic turmoil in Southeast Asia, which led investors to avoid the technology,
telecommunications and general manufacturing companies that we owned, because
they feared that an Asian slowdown would squeeze earnings.

The Portfolio may invest in foreign securities. Foreign investments are subject
to the risk of currency fluctuation and the impact of social, political and
economic change.

(*)  Lipper provides data on a monthly basis, so for comparative purposes the
     Lipper Average and Index since inception returns reflect the Portfolio's
     closest calendar month-end performance of 9/30/88.

(1)  Past performance is not predictive of future performance. Portfolio
     performance is net of investment fees and fund expenses but not product
     charges.

(2)  The Lipper Variable Insurance Products (VIP) Global Average is calculated
     by Lipper Analytical Services, Inc., and reflects the investment return of
     certain portfolios underlying variable life and annuity products. These
     returns are net of investment fees and fund expenses but not product
     charges.

(3)  The Morgan Stanley Index is a weighted index comprised of approximately
     1,500 companies listed on the stock exchanges of the U.S.A., Europe,
     Canada, Australia, New Zealand and the Far East. The combined market
     capitalization of these companies represents approximately 60% of the
     aggregate market value of the stock exchanges in the countries comprising
     the World Index. The World Index is an unmanaged index that includes the
     reinvestment of all dividends but does not reflect the payment of
     transaction costs and advisory fees associated with an investment in the
     Portfolio. The securities that comprise the World Index may differ
     substantially from the securities in the Portfolio. The World Index is not
     the only index that may be used to characterize performance of global
     funds, and other indexes may portray different comparative performance.

Performance Review.

Location, Location, Location. This year, where you owned stocks was more
important than which stocks you owned. In southeast Asia, economies became
overheated. The Japanese economy was emerging from the doldrums. Europe
continued its slow progress into an expansion and the mature U.S. economic cycle
was in extended cruising mode. Our performance suffered because we held too much
in Japan and too little in the U.S.

Asia was in crisis. We were wrong on the direction of the Japanese economy. Most
investors continued to favor the most well known Japanese stocks: exporters such
as Toyota. The downturn in Japan and the surprising spread of the problems of
Thailand and Malaysia had consequences in unexpected places.

We were focused on Europe. We thought Continental Europe was the place to be and
we benefited from our holdings there.


                                       28

Strategy Session.

A Turning Point in Asia. We thought that Japan was going to emerge from its
prolonged economic lethargy and accordingly invested in companies that would
benefit from greater domestic spending. However, in April the Japanese
government increased its consumption tax, destroying consumer confidence and
stalling Japan's economic recovery.

To make things worse, credit and currency problems in Thailand and Malaysia
became acute, prompting a widespread investor flight from emerging market
countries and reducing the market for Japanese export goods. We generally have
avoided the most overheated economies in Southeast Asia and are likely to stay
out until conditions stabilize. We also are reducing our holdings in Japan and
are less focused on companies that would benefit from an economic recovery
there.

And in Europe. The prospect of European economic union and the example of U.S.
firms have produced widespread restructuring of European companies to improve
their productivity. Several industries are being transformed by new levels of
entrepreneurialism. For example, we benefited from owning Telecom Italia Mobile
- -- a partly state-owned, but well-managed, mobile telephone company in Italy --
and Hennes & Mauritz -- a multinational specialty retailer, Sweden's largest.
The latter is expanding rapidly in Germany, where its small stores with stylish
merchandise compete with large, sluggish department stores.

The U.S. Economy is Still Attractive. We have increased our holdings in the
United States because its economy and stock market are more stable than
elsewhere. We are focusing on companies that will not face competition from
southeast Asian products, where currency devaluations have created formidable
rivals. We added retailers and health care to our existing focuses on technology
and leisure companies. We believe current stock prices for our technology
holdings are very low and they will rise when the true, modest, magnitude of the
impact of Asian problems on their earnings becomes more widely appreciated.

Outlook

PORTFOLIO MANAGER
Daniel J. Duane

Different Paths for Japan and Europe.

"Europe is in an accelerating stage of its economic cycle and large companies
are reaping the productivity benefits of reorganizations. We expect the kind of
well-managed companies we have been buying to continue their growth in the year
ahead. Europe does less trade with Asia than either the U.S. or Japan, so the
impact of an Asian slowdown should be smaller. Low interest rates and the
benefits of a unified monetary system and market also bode well for European
growth companies."

     reinvestment of all dividends but does not reflect the payment of
     transaction costs and advisory fees associated with an investment in the
     Portfolio. The securities that comprise the S&P 500 may differ

(4)  On September 16, 1994, an investment company that commenced operations on
     August 1, 1988, called Quest for Value Accumulation Trust (the "Old
     Trust"), was effectively divided into two investment funds -- the Old Trust
     and the present OCC Accumulation Trust (the "Present Trust") -- at which
     time the Present Trust commenced operations. The total net assets of the
     Managed Portfolio immediately after the transaction were $682,601,380 in
     the Old Trust and $51,345,102 in the Present Trust. For the period prior to
     September 16, 1994, the performance figures for the Managed Portfolio of
     the Present Trust reflect the performance of the Managed Portfolio of the
     Old Trust.

Investment Goal

Growth of capital over time.

Types of Investments

Primarily common stocks, bonds and cash equivalents.

Investment Style

The Portfolio uses a fundamental, bottom-up process of value investing. It has
the ability to move in and out of equities depending on what best suits the
current market environment. Most of the time, however, the Portfolio will be
heavily weighted in equities.

Performance Review.

We performed well in 1997 despite a large cash position in a rising stock
market. The Portfolio's cash reserve of 28% of assets at the end of December is
a buffer against market volatility. We plan to use this cash to buy stocks we
like whenever they are available at attractive prices.

Many of the Portfolio's stocks did extremely well in the year. Among the top 10
holdings, Time Warner, Federal Home Loan Mortgage, Lockheed Martin and
BankBoston all rose sharply.

We established new positions in such stocks as Dow Chemical and Diageo. Dow is
improving its earnings by divesting underperforming businesses to concentrate on
those with the best returns. Diageo is a global consumer products giant formed
through the recent merger of Grand Metropolitan and Guinness. Its many
well-known brands include Burger King, Pillsbury and Smirnoff.

Strategy Session.

We are long-term investors in superior companies which have strong competitive
positions, generate high cash flow and deploy that cash to benefit shareholders.
Moreover, we want to buy their shares at reasonable prices. Our objectives are:
a) preserve capital, don't lose it; and b) generate excellent returns for the
Portfolio's shareholders.

A major issue facing investors today is the Asian financial crisis. For
U.S.-based multinational corporations, the crisis is negative in all short-term
respects: growth, profits and currency translation. However, the long-term
effect for many U.S. multinationals could be positive. We see this risk/reward
opportunity in several of the Portfolio's holdings, including McDonald's (fast
food), Caterpillar (earth-moving equipment and engines) and Citicorp (banking).
Each may suffer short term, but we believe that all will benefit longer term.

One of McDonald's challenges in Asia had been the very high cost of store
locations in cities. In many cases, these locations are now "on sale" at greatly
reduced prices, making it easier for McDonald's to expand. Caterpillar's
powerful system of independent distributors should emerge undamaged from the
Asian crisis, whereas competitors' much weaker distributors could be crippled.
Citicorp had been reducing its risks in Asia for two years. Now that competition
is diminishing and lending spreads are likely to improve, it can expand without
the capital impairment that is likely to restrict many other banks in the
region.

McDonald's, Caterpillar and Citicorp illustrate our buy-and-hold philosophy. We
focus on individual companies and try to understand where their businesses are
going over the next several years, not on where the stock market is heading in
the next quarter. We believe long-term investment in quality businesses offers
an effective way to achieve superior returns without taking large risks.

Outlook

PORTFOLIO MANAGER
Richard J. Glasebrook II

"The stock market has been exceptionally strong three years in a row, and
investors should be realistic that the next few years could be less rewarding.
However, we don't get wrapped up in attempting to guess whether the stock market
will be up or down in the coming quarter or year. We believe wealth is created
by investing for the long term in businesses that can increase the value of
shareholders' capital through all market conditions. Even taking into account
periods of poor performance, stocks have outperformed other types of investments
for nearly every five-year period since the Depression. To us, this dictates
consistent long-term investment as the best way to make money."

OCC
Accumulation Trust Small Cap Portfolio

Performance Summary.

The OCC Accumulation Trust Small Cap Portfolio performed well in 1997. Its total
return of 22.24% exceeded the 19.59% average total return for the 59 small cap
funds monitored by Lipper's Variable Insurance Products (VIP) Performance
Analysis Service and trailed slightly the 22.36% return of the Russell 2000
Index. For the five years ended December 31, 1997, the Portfolio's average
annual total return of 14.61% compared with an average of 17.04% for the eight
funds in the Lipper category and 16.41% for the Russell 2000. Returns for the
Portfolio take into account expenses incurred by the Portfolio, but not separate
account charges imposed by the insurance company.

================================================================================

Investment Goal

Capital appreciation.

Types of Investments

Primarily equity securities of small companies with a market capitalization of
under $1 billion.

Investment Style

The Portfolio employs a fundamental, bottom-up process of value investing. The
Portfolio seeks underpriced securities that often occur in this sector of the
market due to lower Wall Street coverage.

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

Performance Review.

We maintained a relatively defensive investment posture throughout 1997. This
included an above-average cash position of 12% of net assets at year end, with
88% of assets in common stocks.

By being somewhat defensive, and by continuing to invest in reasonably valued
companies based on their business fundamentals, we avoided the dramatic price
volatility experienced by many small cap investors in 1997.

The five stocks which contributed most to performance in 1997 were E.W. Blanch
Holdings, Keystone International, ACC Corp., International Imaging Materials and
WestPoint Stevens.

The five which detracted most were Nu-Kote Holding, Katz Media Group, Repap
Enterprises, Moneygram Payment Systems and CommScope. CommScope is the only one
of the five still owned by the Portfolio. It manufactures electronic and
fiber-optic cables for telecommunications and cable TV.
<PAGE>

Strategy Session.

The small cap market sprang to life in the third quarter, outperforming large
capitalization stocks, then lagged in the fourth quarter due in part to investor
concerns about the impact of the Asian financial crisis. Apart from the third
quarter, small caps as a class have now underperformed large caps for three
years. We believe many quality small cap issues are undervalued at this time.

We invest in companies that have a significant record of earnings and revenue
growth, generate sizable free cash flow, have high cash flow returns on assets
and have quality balance sheets. We purchase these companies at attractive
multiples relative to the market and to where they have traded in the past.

WestPoint Stevens highlights the characteristics we look for in a company. It is
the leading U.S. manufacturer of sheets and towels. It is well managed and
strongly profitable, has excellent growth prospects and is attuned to the
interests of shareholders. Generating significant free cash flow, the company
reinvests a portion of this money in its business at high rates of return and
uses a portion for an aggressive share repurchase program. By reducing the
number of shares outstanding, it increases the value of those remaining. Despite
these superior business characteristics, the stock trades at what we consider to
be a modest valuation.

During the year, we established new positions or added to existing positions in
an array of companies such as Watkins-Johnson, which makes semiconductor
manufacturing equipment and electronic products; Belden, which manufactures wire
and cable; and National Patent Development, a holding company which owns General
Physics, a provider of training to business and government.

Outlook

PORTFOLIO MANAGER
The OCC Accumulation Trust Small Cap Management Team

"The small cap sector appears to be undervalued relative to large caps. Since
its introduction in 1979, the Russell 2000 Index, a small cap benchmark, has had
an average price/earnings ratio equal to 125% of the price/earnings ratio of the
Standard & Poor's 500 Index, a large cap benchmark. At this time, the Russell
2000 is moderately below that historic relationship.

"Of course, we invest in individual stocks, not the index. Our philosophy is to
buy reasonably valued smaller companies with strong business fundamentals. By
being disciplined in our approach, we seek to control risk and deliver superior
returns for shareholders."

Warburg
Pincus Trust Post-Venture Capital Portfolio

Performance Summary.

For the 12 months ended December 31, 1997, Warburg Pincus Trust Post-Venture
Capital Portfolio had a total return of 13.34%. Its benchmarks, the Lipper
Variable Annuity Small Cap Index and the Russell 2000 Growth Index, had returns
of 18.32% and 12.95%, respectively, for the period.

The reporting period saw considerable volatility among stocks targeted by the
Portfolio, i.e., smaller-cap and aggressive-growth issues. All told, this
resulted in gains for such stocks collectively.

The Portfolio is designed for investors seeking an aggressive investment
strategy. Because of the nature of the Portfolio's holding and certain
strategies it may use, an investment involves certain risks and may not be
appropriate for all investors.

Investment Goal

Long-term growth of capital.

Types of Investments

Primarily equity securities of issuers in their post-venture capital stage of
development.

Investment Style

This Portfolio looks for post-venture capital companies that, within the past 10
years, have received venture capital financing, distributed securities to
venture capital investors or engaged in an initial public offering and offer
potential for strong growth, regardless of size.

Performance Review.

For the 12 months ended December 31, 1997, the Portfolio was subject to several
significant shifts in investor sentiment. Through April, the Portfolio's
holdings suffered sizable losses. This was due to fears of higher interest
rates, as well as earnings disappointments announced by several prominent
technology companies. Sentiment toward aggressive-type stocks improved
dramatically in May. Such stocks continued to rally though September, fueled by
profit warnings from several large-cap growth stocks. Finally, small-cap and
rapid-growth stocks finished the period on a weak note. Given concerns about
economic and currency turmoil in Asia, investors took refuge in investments with
perceived greater short-term stability at the expense of more aggressive issues.
Against this backdrop, the Portfolio posted a respectable gain vs. its
benchmarks for the period. Good performers for the Portfolio during the 12
months included its technology, financial and retail holdings.

Strategy Session.

As of December 31, the Portfolio was concentrated in the high-growth area
favored by venture capitalists. This included, notably, a substantial presence
in domestic technology companies, which we believe will continue to be the
engines of global economic growth. Here, the Portfolio maintained sizable
positions in both the electronics and computer areas. Other significant sector
weightings for the Portfolio included business services, where we focused on
companies benefiting from the growth of corporate outsourcing; financial
services, including asset-management and insurance companies; and retail, where
we continued to find reasonable priced growth. Going forward, our focus will
remain on well-managed, well-financed companies offering innovative products and
services and sustainable business models.

Outlook

CO-PORTFOLIO MANAGERS
Elizabeth B. Dater
Stephen J. Lurito

"At Warburg Pincus our expertise in researching venture capital-financed
companies helps us identify companies with strong growth potential we can pass
on to investors. We believe that venture capital participation in the early
stages of a company's development can lead to higher growth rates than those of
the older, public companies in the Dow Jones Industrial Average or the Fortune
500."

                      NOTES TO THE FINANCIAL STATEMENTS OF
             CERTAIN PORTFOLIOS OF THE PRUDENTIAL SERIES FUND, INC.
 
NOTE 1:  GENERAL
 
The Prudential Series Fund, Inc. ("Series Fund"), a Maryland corporation,
organized on November 15, 1982, is a diversified open-end management investment
company registered under the Investment Company Act of 1940, as amended. The
Series Fund is composed of fifteen Portfolios ("Portfolio" or "Portfolios"),
each with a separate series of capital stock. The information presented in thse
financial statements pertains to only the eight Portfolios available for
investment by Discovery Select: Money Market Portfolio, Diversified Bond
Portfolio, High Yield Bond Portfolio, Stock Index Portfolio, Equity Income
Portfolio, Equity Portfolio, Prudential Jennison Portfolio and Global Portfolio.
Shares in the Series Fund are currently sold only to certain separate accounts
of The Prudential Insurance Company of America ("The Prudential"), Pruco Life
Insurance Company and Pruco Life Insurance Company of New Jersey (together
referred to as the "Companies") to fund benefits under certain variable life
insurance and variable annuity contracts ("contracts") issued by the Companies.
The accounts invest in shares of the Series Fund through subaccounts that
correspond to the Portfolios. The accounts will redeem shares of the Series Fund
to the extent necessary to provide benefits under the contracts or for such
other purposes as may be consistent with the contracts. The ability of the
issuers of the securities held by the Money Market Portfolio to meet their
obligations may be affected by economic developments in a specific industry or
region.
 
NOTE 2:  ACCOUNTING POLICIES
 
The following is a summary of significant accounting policies consistently
followed by the Series Fund in the preparation of its financial statements.
 
SECURITIES VALUATION:  Securities traded on an exchange (whether domestic or
foreign) are valued at the last reported sales price on the primary exchange on
which they are traded. Securities traded in the over-the-counter market
(including securities listed on exchanges for which a last sales price is not
available) are valued at the average of the last reported bid and asked prices.
Convertible debt securities are valued at the mean between the most recently
quoted bid and asked prices provided by principal market makers. High yield
bonds are valued either by quotes received from principal market makers or by an
independent pricing service which determine prices by analysis of quality,
coupon, maturity and other factors. Any security for which a reliable market
quotation is unavailable is valued at fair value as determined in good faith by
or under the direction of the Series Fund's Board of Directors.
 
The Money Market Portfolio uses amortized cost to value short-term securities.
Short-term securities that are held in the other Portfolios which mature in more
than 60 days are valued at current market quotations and those short-term
securities which mature in 60 days or less are valued at amortized cost.
 
The High Yield Bond Portfolio may hold up to 15% of its net assets in illiquid
securities, including those which are restricted as to disposition under
securities law ("restricted securities"). Certain issues of restricted
securities held by the High Yield Bond Portfolio at December 31, 1997 include
registration rights, some of which are currently under contract to be
registered. Restricted securities, sometimes referred to as private placements,
are valued pursuant to the valuation procedures noted above.
 
REPURCHASE AGREEMENTS:  In connection with transactions in repurchase agreements
with U.S. financial institutions, it is the Series Fund's policy that its
custodian or designated subcustodians, as the case may be under triparty
repurchase agreements, take possession of the underlying collateral securities,
the value of which exceeds the principal amount of the repurchase transaction
including accrued interest. 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 Series Fund may
by delayed or limited. (See Note 5).
 
FOREIGN CURRENCY TRANSLATION:  The books and records of the Series Fund are
maintained in U.S. dollars. Foreign currency amounts are translated into U.S.
dollars on the following basis:
 
(i) market value of investments securities, other assets and liabilities - at
the current rates of exchange.
 
                                       64
<PAGE>
(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 Series Fund are presented at the foreign exchange
rates and market values at the close of the fiscal year, the Series Fund does
not isolate that portion of the results of operations arising as a result of
changes in the foreign exchange rates from the fluctuations arising from changes
in the market prices of securities held at the end of the fiscal year.
Similarly, the Series 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 fiscal year. Accordingly,
these realized and unrealized foreign currency gains (losses) are included in
the reported net realized gains (losses) on investment transactions.
 
Net realized gains (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 Series 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 fiscal year end exchange rates are reflected as a component of
net unrealized appreciation (depreciation) 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.
 
SHORT SALES:  Certain portfolios of the Series Fund may sell a security it does
not own in anticipation of a decline in the market value of that security (short
sale). When the Portfolio makes a short sale, it must borrow the security sold
short and deliver it to the buyer. The proceeds of the short sale will be
retained by the broker-dealer through which it made the short sale as collateral
for its obligation to deliver the security upon conclusion of the sale. The
Portfolio may have to pay a fee to borrow the particular security and may be
obligated to remit any interest or dividends received on such borrowed
securities. A gain, limited to the price at which the Portfolio sold the
security short, or a loss, unlimited in magnitude, will be recognized upon the
termination of a short sale if the market price at termination is less than or
greater than, respectively, the proceeds originally received.
 
OPTIONS:  The Series Fund may either purchase or write options in order to hedge
against adverse market movements or fluctuations in value with respect to
securities which the Series Fund currently owns or intends to purchase. The
Series Fund's principal reason for writing options is to realize, through
receipts of premiums, a greater current return than would be realized on the
underlying security alone. When the Series Fund purchases an option, it pays a
premium and an amount equal to that premium is recorded as an investment. When
the Series Fund writes an option, it receives a premium and an amount equal to
that premium is recorded as a liability. The investment or liability is adjusted
daily to reflect the current market value of the option. If an option expires
unexercised, the Series Fund realizes a gain or loss to the extent of the
premium received or paid. If an option is exercised, the premium received or
paid is an adjustment to the proceeds from the sales or the cost of the purchase
in determining whether the Series Fund has realized a gain or loss. The
difference between the premium and the amount received or paid on effecting a
closing purchase or sale transaction is also treated as a realized gain or loss.
Gain or loss on purchased options is included in net realized gain (loss) on
investment transactions. Gain or loss on written options is presented separately
as net realized gain (loss) on written option transactions.
 
The Series Fund, as writer of an option, may have no control over whether the
underlying securities may be sold (called) or purchased (put). As a result, the
Series Fund bears the market risk of an unfavorable change in the price of the
security underlying the written option. The Series Fund, as purchaser of an
option, bears the risk of the potential inability of the counterparties to meet
the terms of their contracts.
 
FINANCIAL FUTURES CONTRACTS:  A financial futures contract is an agreement to
purchase (long) or sell (short) an agreed amount of securities at a set price
for delivery on a future date. Upon entering into a financial futures contract,
the Series 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 Series Fund each day, depending on the
daily fluctuations in the value of the underlying security. Such variation
margin is recorded for financial
 
                                       65
<PAGE>
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 Series Fund invests in financial futures contracts in order to hedge its
existing portfolio securities or securities the Series Fund intends to purchase,
against fluctuations in value. Under a variety of circumstances, the Series 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 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; interest income, which is comprised of four elements: stated
coupon, original issue discount, market discount and market premium is recorded
on the accrual basis. Certain portfolios own shares of real estate investment
trusts ("REITs") which report information on the source of their distributions
annually. A portion of distributions received from REITs during the period is
estimated to be a return of capital and is recorded as a reduction of their
costs. During the year ended December 31, 1997, certain Portfolios purchased
securities from and sold securities to other Portfolios of the Series Fund or
other funds or accounts managed by The Prudential or its affiliates in
accordance with the provisions of Rule 17a-7 of the Investment Company Act of
1940. Expenses are recorded on the accrual basis which may require the use of
certain estimates by management. The Series Fund expenses are allocated to the
respective Portfolios on the basis of relative net assets except for expenses
that are charged directly at a Portfolio level.
 
CUSTODY FEE CREDITS:  The Series Fund, exclusive of the Global Portfolio, has an
arrangement with its custodian bank, whereby uninvested monies earn credits
which reduce the fees charged by the custodian. Such custody fee credits are
presented as a reduction of gross expenses in the accompanying Statement of
Operations.
 
TAXES:  For federal income tax purposes, each portfolio in the Series Fund is
treated as a separate taxpaying entity. It is the intent of the Series Fund to
continue to meet the requirements of the Internal Revenue Code applicable to
regulated investment companies and to distribute all of its net 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 Series Fund's understanding of the
applicable country's tax rules and regulations.
 
DIVIDENDS AND DISTRIBUTIONS:  Dividends and distributions of each Portfolio are
declared in cash and automatically reinvested in additional shares of the Fund.
The Money Market Portfolio will declare and reinvest dividends from net
investment income and net realized capital gain (loss) daily. Each other
Portfolio will declare and distribute dividends from net investment income,if
any, quarterly 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.
 
RECLASSIFICATION OF CAPITAL ACCOUNTS:  The Series 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 Gains, and
Return of Capital Distributions by Investment Companies. As a result of this
statement, the Series Fund changed the classification of distributions to
shareholders to disclose the amounts of undistributed net investment income and
accumulated net realized gain (loss) on investments available for distributions
determined in accordance with income tax regulations. For the fiscal year ended
December 31, 1997, the application of this statement increased (decreased) net
unrealized appreciation on investments ("APP"), paid-in capital in excess of par

interest, taxes and brokerage commissions) exceeds 0.75% of the Portfolio's
average daily net assets. No refund was required for the fiscal year ended

PIC and Jennison are indirect, wholly-owned subsidiaries of The Prudential.
 
The Series Fund entered into a credit agreement (the "Agreement") on October 28,
1997 with an unaffiliated lender. The maximum commitment under the Agreement is
$250,000,000. The Agreement expires on December 18, 1998. Interest on any such
borrowings outstanding will be at market rates. The purpose of the Agreement is

Series Fund has not borrowed any amounts pursuant to the Agreement as of
December 31, 1997. The Series Fund pays a commitment fee at an annual rate of
 .055 of 1% on the unused portion of the credit facility. The commitment fee is

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
TO THE BOARD OF DIRECTORS AND SHAREHOLDERS OF THE PRUDENTIAL SERIES FUND, INC.:
 
In our opinion, the accompanying statements of assets and liabilities, including
the schedules of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of the Money Market, Diversified Bond,
High Yield Bond, Stock Index, Equity Income, Equity, Prudential Jennison and
Global Portfolios (eight of the fifteen portfolios that constitute The
Prudential Series Fund, Inc.; the "Portfolios") at December 31, 1997, the
results of each of their operations for the year then ended and the changes in
each of their net assets and the financial highlights for each of the two years
in the period then ended, in conformity with generally accepted accounting
principles. These financial statements and the financial highlights (hereafter
referred to as "financial statements") are the responsibility of the Portfolios'
management; our responsibility is to express an opinion on these financial
statements based on our audits. We conducted our audits of these financial
statements in accordance with generally accepted auditing standards which
require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits, which included
confirmation of securities at December 31, 1997 by correspondence with the
custodian and brokers and the application of alternative auditing procedures
where confirmations from brokers were not received, provide a reasonable basis
for the opinion expressed above. The financial highlights of the Prudential
Jennison Portfolio for the period April 25, 1995 through December 31, 1995 and
the financial highlights for each of the three years in the period ended
December 31, 1995 for each of the other seven portfolios were audited by other
independent accountants whose report thereon dated February 15, 1996 expressed
an unqualified opinion on those financial highlights.
