        PBHG Growth II Portfolio


Dear Shareholder:

The PBHG Insurance Series Fund, Inc. - PBHG Growth II Portfolio returned 8.19%
for the fiscal year ended December 31, 1998. This compares with the Russell
Midcap Growth Index return of 17.87%. The major factors that led to the
under-performance included a modest overweight in energy stocks relative to the
benchmark throughout the year, as well as the continued strength of market
cap-weighted indexes relative to equally weighted benchmarks. As an example of
the latter, an equally weighted return for the Russell Midcap Growth Index was
9.0%, about half of the market cap weighted return. This same phenomenon
occurred among large cap stocks as well. According to a January 7, 1999 research
report by Morgan Stanley Dean Witter analyzing the performance of the S&P 500
Index during 1998, "5 stocks in the index contributed 25% of the performance of
the index and 15 stocks accounted for half of the performance. . . an
equal-weighted version of the S&P 500 would have returned 13.5% in 1998 - less
than half the return of the market-cap weighted version."

As 1998 came to an end, many of the problems that had appeared so threatening
earlier in the year lost their intensity. Investors became less concerned with
the "Asian contagion" and the threat of global economic problems. Thanks to the
Federal Reserve's three rate cuts, strong employment data and an ever-spending
consumer, the fear of a U.S. recession subsided. The year ended on a positive
note, with the Conference Board reporting that the index of leading economic
indicators rose 0.6% in November, the largest one-month rise in almost two
years. During the earlier part of the year, the market often reacted strongly
and negatively to major news stories. During the latter part of the year, the
markets seemed to focus on good news and ignore bad news. Amazingly, the markets
seemed to shrug off the bombing of Iraq and the impeachment of the President.
Persistent rumors of the possible resignation of Treasury Secretary Robert Rubin
and the announcement of several large mergers/acquisitions appeared to elicit
more response from the market.

Among the different sectors of the market, by far the weakest were the energy
and finance sectors. Energy was affected by weak commodity prices for oil and
gas as the international economic slowdown put a drag on demand. Financials were
hurt by a global liquidity scare that affected companies that rely on asset
securitizations for ongoing access to capital. Technology was strong throughout
the year, with software and services performing well during the first three
quarters of 1998, followed by a rapid rebound in hardware companies in the
fourth quarter, including semiconductors, peripherals and semiconductor capital
equipment.

Looking ahead, we are optimistic that the market will more fairly reward
companies that are able to achieve analysts' earnings expectations. It seems to
us that in an economic environment characterized by a more difficult and slower
setting for earnings, smaller, niche-oriented companies should be more sought
after by investors. Certainly relative valuations for smaller companies continue
to look attractive, especially for the most rapidly growing type of mid-sized
companies that make up the Portfolio.

In our opinion, investor confidence in small- and mid-cap growth stocks needs
the backdrop of a strong market. A strong market needs reasonably good earnings,
stable inflation and interest rates, and a stable attitude on the part of
investors about the appropriate risk premium to assign to various parts of the
market. Because it is impossible to predict these variables with any certainty,
we continue to pursue a strategy of investing in the best mid-sized growth
companies that we can find.

In closing, we thank you for your confidence in Pilgrim Baxter & Associates,
Ltd. and in the PBHG Insurance Series Fund, Inc.


Sincerely,


/s/ Jeffrey A. Wrona

        PBHG Technology & Communications Portfolio

Dear Shareholder:

The PBHG Insurance Series Fund, Inc. - PBHG Technology & Communications
Portfolio ended its second fiscal year on December 31, 1998. Last year was one
of the most volatile and tumultuous years in recent memory. The market's
activity in 1998 emphasized the degree to which world financial markets have
become integrated. Domestically, the United States continued to enjoy an almost
ideal economic environment that combined solid economic growth, declining
interest rates, low unemployment and low inflation. Despite the sanguine
environment here at home, the market's fortunes throughout the year continued to
turn on the question of whether the U.S. economy would be affected by the
continuing emerging markets financial crisis.

Almost all returns within the technology sector occurred in the first and fourth
quarters of the year. Stocks staged a strong rally in the early part of the year
as economic and earnings reports led investors to believe that the U.S. had
avoided any serious impact from the unfolding economic debacle in Asia. As the
year wore on, stocks paused as investors began to worry that the events abroad
would not slow the economy down enough to prevent a round of interest rate hikes
by the Federal Reserve. However, late April and early May brought favorable
economic data that seemed to indicate that Asian difficulties were beginning to
slow the overheated U.S. economy at the perfect time.

Through the summer, it became clear that the emerging market crisis was not
over. The problems in Asia had lowered demand, and therefore prices, for
petroleum and other commodities. Lower commodity prices decreased the hard
currency receipts that Russia and other emerging market countries depended on to
remain solvent, and the crisis quickly spread. The U.S. market reached new highs
in mid-July, but then suffered the first of two harrowing sell-offs as investors
again focused on international concerns. The market recovered in September, but
sold off again when risky emerging market bets brought a large U.S. hedge fund
to its knees. By October 8th, the S&P 500 Index had declined slightly more than
19%, close to the 20% decline that defines a "bear market." Fortunately, the
Federal Reserve stepped in and brokered a bail-out for the stumbling hedge fund,
Long-Term Capital, and also began cutting interest rates. Stocks usually fair
well in declining interest rate environments and the rate cuts set off a furious
rally. By year-end, the S&P 500 Index had recovered all of its losses and more
as it finished 1998 at new highs.

The PBHG Technology & Communications Portfolio returned 32.20% for the year
versus its benchmarks the Pacific Stock Exchange High Technology (PSE) Index
return of 54.61% and the Soundview Technology Index return of 42.33%. A great
deal of the performance disparity between the Portfolio and the benchmarks can
be explained by the continued out-performance of large capitalization stocks.
During 1998, the S&P 500, an index containing large U.S. companies, outperformed
the small-capitalization Russell 2000 Index by 31.15%. (The S&P 500 was up
28.59% while the Russell 2000 declined 2.56%.) Large company out-performance
also occurred within indexes. According to a January 7, 1999 research report by
Morgan Stanley Dean Witter analyzing the performance of the S&P 500 Index during
1998, the largest 100 stocks in the S&P 500 Index accounted for a
disproportionate 85% of the benchmark's return. Put another way, the other 400
stocks in that Index accounted for only 15% of the S&P 500's return.

        PBHG Technology & Communications Portfolio

The disparity between large and small company stock performance also occurred in
the technology sector, where the largest technology indexes significantly
outperformed smaller capitalization Indexes. We increased the size of the
average company in the Portfolio throughout the year to take advantage of the
trend favoring large stocks. However, we also continued to follow a disciplined
methodology that, in our opinion, leads us to select the companies that exhibit
the very best fundamentals. When faced with the choice between fundamentals and
other factors, such as this year's size bias in the market, we will always favor
those stocks with the best growth characteristics. As a direct result, while the
size of the average stock holding did increase during the year, our Portfolio
continues to contain many more small companies than our benchmark.

At year end, the weighted-average market capitalization of the PBHG Technology
and Communications Portfolio was roughly one-third that of the PSE Index and
Soundview Technology Index, but the next twelve months' estimated earnings
growth was 20% greater. We believe that, over time, stock appreciation follows
earnings growth. Historically, faster growing, smaller companies have enjoyed
better stock price appreciation, when compared to the market as a whole. In our
opinion, the greater risk aversion caused by the emerging market crisis led
investors to gravitate to larger, more liquid stocks in 1998. Fortunately, no
trend lasts forever and we believe that slowing earnings growth at larger
companies, which are more exposed to overseas markets, will continue in 1999.
Inevitably, we think this will lead investors to pay more attention to the
rapidly growing small and mid-cap companies that continue to make up a large
part of the PBHG Technology and Communications Portfolio.

Sincerely,                                    Sincerely,

        PBHG Select 20 Portfolio

Dear Shareholder:

The PBHG Insurance Series Fund, Inc. - PBHG Select 20 Portfolio returned 62.52%
for the fiscal year ended December 31, 1998. This compares favorably to the
returns provided by our two benchmark indices, the S&P 500 Index at 28.59% and
the Russell Top 200 Growth Index at 45.08%. In our opinion, the advantages of
concentrated investing -- focusing on a limited number of stocks that we are
convinced have the greatest fundamental strengths in their underlying businesses
- -- were borne out in the results of the PBHG Select 20 Portfolio in 1998. Though
we had a few disappointments during the year, the benefit of having substantial
positions in several of the market's top performers easily compensated for the
negative effects of our disappointing stocks. Fortunately, several portfolio
holdings appreciated by more than 100% for the year.

As you know, we make no attempt to limit sector exposure in the Portfolio. Our
goal is to invest in our twenty best large-cap ideas, regardless of sector. As a
result, we consistently over-weighted the Portfolio in the technology sector,
which proved fortunate. Seven of our top ten performers were technology stocks.
This sector made the biggest contribution to Portfolio performance in each
quarter of 1998 and was the only sector that produced a positive return in every
quarter. Remarkably, technology produced the best monthly sector performance
seven times during the year. This noteworthy consistency of performance may seem
unusual given that the technology sector is often derided as being unpredictable
and unmanageable. However, in our opinion, technology remains the fastest
growing sector of our economy and thus the area to find the greatest number of
high-quality, fast-growing companies.

Our other heavily represented sectors -- services, healthcare, and consumer --
all contributed positively to the Portfolio's performance in 1998, though with
greater quarterly variability. The Portfolio benefited from our decision to exit
the energy sector in the first quarter, just as prices for oil and natural gas
began to decline due to dramatic slowdowns in a number of the world's regional
economies. Fortunately, we also sold our holdings in the financial services
sector in July, prior to the global liquidity scare that negatively affected
many stocks in that sector. During 1998, the Portfolio had no exposure to the
commodity-oriented industrial/basic materials sector, which proved beneficial as
those companies' profits suffered because of slackening demand around the world.

As mentioned above, not all of our Portfolio's investments worked in 1998.
Deteriorating fundamentals prompted the sale of a number of holdings, some
before the share price collapsed and, unfortunately, some after. We recognize
that investors dislike negative surprises. Consequently, we plan to work even
harder in 1999 to discern changes at the margin in the fundamental business
trends of the companies we own -- changes that we believe portend negative
outcomes going forward. While we fully expect a few negative surprises, we will
strive to better anticipate them, and take the appropriate actions.

It is clear that investors favored large cap growth stocks above all others
during 1998. Determining factors seemed to be sustainable, above-average rates
of growth in a challenging aggregate growth environment, and trading liquidity
that allowed investors to react quickly if deemed necessary. In addition to the
strong business fundamentals evidenced by our companies, we think these two
factors also contributed to the Portfolio's performance over the course of 1998.
At least to some extent, we are grateful for having been in the right place at
the right time. Nonetheless, we continue to believe that high quality, strong
secular (not cyclical) growth companies consistently represent the most
promising investment opportunities.

As we enter 1999, the equity markets are in a decidedly bullish mood. Recent
concerns about economic problems around the world, hedge fund shenanigans,
terrorist activities, war with Iraq and even the historic impeachment of an
American President appear to have dissipated among investors. While we do not
expect a major sustained downdraft in equity markets in the presence of a low
interest rate environment, a stable U.S. economy, and an accommodating Federal
Reserve, we also do not expect the current euphoria to last all year. One
feature we do expect the equity markets to have in common with 1998 is
volatility. Volatility correlates directly with valuation levels, and with
valuations at historically high levels, we do not expect many dull moments.

We continue to like the long-term prospects of the growth companies we own.
Superior technologies or services, balance sheets, business models, and ability
to execute are all characteristics commonly found in top quality growth
companies that contribute to sustained, above-average growth rates. We believe
companies with these characteristics will continue to be sought out by
investors.

In closing, we thank you for your confidence in Pilgrim Baxter & Associates,
Ltd., and in the PBHG Insurance Series Fund, Inc.

        PBHG Large Cap Value Portfolio


Dear Shareholder:

For the fourth quarter of 1998, the PBHG Insurance Series Fund, Inc. - PBHG
Large Cap Value Portfolio returned 29.59% versus 21.30% for the S&P 500 Index.
For the year ended December 31, 1998 the PBHG Large Cap Value Portfolio returned
37.96% versus 28.59% and 15.64% for the S&P 500 and Russell 1000 Value
benchmarks, respectively.

The Fed easing sparked a sharp rally in the fourth quarter. Federal Reserve
easings have historically been a strong positive influence on stock market
returns, and there is no reason to expect this cycle to depart from past norms.
While the Fed lowered rates three times last fall, the cumulative reduction only
amounted to 75 basis points. As a result, the yield curve has not (yet) shifted
to the steep positive slope we initially anticipated. Fortunately, with Fed
Funds at 4.75% and inflation currently running around 1%-2%, we believe Alan
Greenspan has ample room to lower short-term interest rates further over the
course of 1999. Although current Federal Reserve pronouncements suggest that
lower short rates are unlikely over the near-term, we are optimistic that
ongoing global imbalances such as Brazil's recent currency crisis, will
eventually prompt the Fed to ease more assertively. Until then, however, we'd
expect the market to trade sideways in volatile fashion.

Finally, no stock market commentary is complete today without a remark about the
Internet. In the past 20 years, we have watched a number of manias come and go -
most notably, video games, biotechnology, home shopping and physicians practice
management companies. Nevertheless we have never seen a boom on as large a scale
as the Internet craze. At its recent price of $130, Internet bookseller
Amazon.com has appreciated 13-fold over the past twelve months, and now sports a
market capitalization of approximately $20 billion, on par with blue-chip giants
Eastman Kodak and Dow Chemical. Though Amazon.com has sales of $1 billion, it
will lose money for the foreseeable future. Even stranger, the company's market
cap is more than quadruple the combined market cap of the two largest book
retailers, Barnes & Noble and Borders Group!

With that said, we should note that while the highly-visible Internet stocks
have wildly exceeded any rational valuation parameters, the impact of the
Internet on business and life around the world will quite possibly be the
defining event of the 21st Century. Furthermore, companies that benefit from the
Internet boom do not all have names ending in ".com". For example, the
Portfolio's fourth quarter results were helped by its holdings of regional
telephone companies, which should profit from the proliferation of new phone
lines dedicated to Internet access. Also, IBM performed well in the quarter, as
its outlook was improved by renewed demand for its mainframe computers that
drive the giant databases required by e-commerce. Therefore, while we currently
believe it is prudent to avoid speculative Internet stocks, we are continually
on the lookout for mainstream investment ideas whose current business trend is
accelerated by the e-commerce phenomena.

In closing, we thank you for your confidence in Pilgrim Baxter Value Investors,
Inc. and in the PBHG Insurance Series Fund, Inc.


Sincerely,

        PBHG Small Cap Value Portfolio


Dear Shareholder:

For the fourth quarter of 1998, the PBHG Insurance Series Fund, Inc. - PBHG
Small Cap Value Portfolio returned 25.92% versus 16.31% for the Russell 2000
Index. For the year ending December 31, 1998 the PBHG Small Cap Value Portfolio
returned 10.94% versus (2.56)% for the Russell 2000 benchmark.

The Fed's interest rate easing sparked a sharp rally in the fourth quarter.
While the absolute returns of small cap stocks were impressive, the Russell 2000
small cap Index again lagged the S&P 500 Index in the quarter (by approximately
5%). The trailing twelve month gap between large and small stock returns has now
reached 31%, one of the largest performance differentials on record. However,
despite the continued relative underperformance of small stocks, we remain very
positive on the investment outlook for small companies.

Federal Reserve easings have historically been very beneficial for small stock
returns, and we believe there is no reason to expect this cycle to depart from
past norms. Although the Fed lowered rates three times last fall, the cumulative
reduction only amounted to 75 basis points. As a result, the yield curve has not
(yet) shifted to the steep positive slope we initially anticipated. Fortunately,
with Fed Funds at 4.75% and inflation currently running around 1%-2%, we
believe, Alan Greenspan has ample room to lower short-term interest rates
further over the course of 1999. Although current Federal Reserve pronouncements
suggest that lower short-term rates are unlikely over the near-term, we are
optimistic that ongoing global imbalances such as Brazil's recent currency
crisis, will eventually prompt the Fed to ease more assertively.

Finally, no stock market commentary is complete these days without a brief
discussion of the Internet. In the past 20 years, we have watched a number of
manias come and go - most notably, video games, biotechnology, home shopping and
physicians practice management companies. Nevertheless we have never seen a boom
on as large a scale as the Internet craze. At its recent price of $130, Internet
bookseller Amazon.com has appreciated 13-fold over the past twelve months, and
now sports a market capitalization of approximately $20 billion, on par with
blue-chip giants Eastman Kodak and Dow Chemical. Though Amazon.com has sales of
$1 billion, it will lose money for the foreseeable future. Even stranger, the
company's market cap is more than quadruple the combined market cap of the two
largest book retailers, Barnes & Noble and Borders Group!

With that said, we should note that while the highly-visible Internet stocks
have wildly exceeded any rational valuation parameters, the impact of the
Internet on business and life around the world will quite possibly be the
defining event of the 21st Century. Furthermore, companies that benefit from the
Internet boom do not all have names ending in ".com". For example, early in the
fourth quarter we invested in Banyan Systems, a mediocre computer networking
company, at a little over $3 per share. At that price, the company's networking
business was fairly valued, but there was nothing in the stock price for
Banyan's rapidly growing Internet Switchboard operation. As the Internet craze
rapidly broadened out in November, we began selling your Banyan shares at a
large percentage profit, and sold the last of your Banyan shares at $7.83 per
share - more than a double in less than a quarter!

So, while we are avoiding the speculative Internet stock frenzy, we are
continually on the lookout for investment ideas whose current business trend is
accelerated by the e-commerce phenomena.

In closing, we thank you for your confidence in Pilgrim Baxter Value Investors,
Inc. and in the PBHG Insurance Series Fund, Inc.

NOTES TO FINANCIAL STATEMENTS
As of December 31, 1998
1.  ORGANIZATION
 
The PBHG Insurance Series Fund, Inc. (the "Fund"), a Maryland corporation is
registered under the Investment Company Act of 1940, as amended, as an open-end
management investment company. The Fund consists of seven Portfolios: the PBHG
Growth II Portfolio (the "Growth II Portfolio"), the PBHG Large Cap Growth
Portfolio (the "Large Cap Growth Portfolio"), the PBHG Technology &
Communications Portfolio (the "Technology & Communications Portfolio"), the PBHG
Select 20 Portfolio (the "Select 20 Portfolio"), the PBHG Large Cap Value
Portfolio (the "Large Cap Value Portfolio"), the PBHG Small Cap Value Portfolio
(the "Small Cap Value Portfolio"), and the PBHG Mid-Cap Value Portfolio (the
"Mid-Cap Value Portfolio") (each a "Portfolio" and, collectively, the
"Portfolios"). Each Portfolio is classified as a diversified management
investment company, with the exception of the Select 20 Portfolio which is
classified as a non-diversified management investment company. The financial
statements presented herein do not include the Large Cap Growth Portfolio or the
Mid-Cap Value Portfolio, which are presented separately. Each Portfolio's
prospectus provides a description of the Portfolio's investment objectives,
policies and strategies. The assets of each Portfolio are segregated, and a
shareholder's interest is limited to the Portfolio in which shares are held. The
Fund is intended to be a funding vehicle for variable annuity contracts and
variable life insurance policies to be offered by the separate accounts of life
insurance companies. At December 31, 1998, the following percentage of
outstanding shares of the Portfolios were held by the separate accounts of the
number of participating insurance companies listed below:

                                Percentage of            Number of

2.  SIGNIFICANT ACCOUNTING POLICIES

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

SECURITY VALUATION -- Investment securities of the Portfolios that are listed on
a securities exchange, and for which market quotations are readily available,
are valued at the last quoted sales price at the close of trading on the primary
exchange (currently 4:00 p.m., Eastern time). If there is no such reported sale,
these securities and unlisted securities for which market quotations are not
readily available, are valued at the last bid price.
 
SECURITY TRANSACTIONS AND INVESTMENT INCOME -- Security transactions are
accounted for on the date the securities are purchased or sold (trade date).
Dividend income and distributions to shareholders are recognized on the
ex-dividend date; interest income is recognized on the accrual basis. Costs used
in determining realized capital gains and losses on the sale of investment
securities are those of the specific securities sold adjusted for the accretion
and amortization of acquisition discounts and premiums during the respective
holding periods.
 
DIVIDENDS -- Dividends from net investment income of each Portfolio are declared
annually, if available. Distributions of net realized capital gains, of each
Portfolio, are generally made to shareholders annually, if available. Dividends
from net investment income and distributions from net realized capital gains are
determined in accordance with U.S. Federal income tax regulations, which may
differ from those amounts determined under generally accepted accounting
principles. These book/tax differences are either temporary or permanent in
nature. To the extent these differences are permanent, they are charged or
credited to paid-in-capital, net investment income or accumulated net realized
gain, as appropriate, in the period that the differences arise. Accordingly, the
following permanent differences as of December 31, 1998, primarily attributable
to certain net operating losses which, for tax purposes, are not available to
offset future income or have been used to offset net short-term capital gains,
have been reclassified to the following accounts:
 
                                            Paid-In-Capital
                                            ---------------

Growth II Portfolio                            $ 93,106
Technology & Communications Portfolio          $ 95,178
Select 20 Portfolio                            $203,690
Small Cap Value                                $ 46,830

 
These reclassifications have no effect on net assets or net asset value per
share.
 
FEDERAL INCOME TAXES -- It is each Portfolio's intention to qualify or continue
to qualify as a regulated investment company for Federal income tax purposes and
to distribute all of its taxable income and net capital gains. Accordingly, no
provision has been made for Federal income taxes.
 
NET ASSET VALUE PER SHARE -- The net asset value per share is calculated each
business day by dividing the total value of the Portfolio's assets, less
liabilities, by the number of shares outstanding.
 
REPURCHASE AGREEMENTS -- Securities pledged as collateral for repurchase
agreements are held by a third party custodian bank until the respective
agreements mature. Provisions of the repurchase agreements and procedures
adopted by the Fund and followed by Pilgrim Baxter & Associates, Ltd. (the
"Adviser") ensure that the market value of the collateral including accrued
interest thereon, is sufficient in the event of default by the counterparty. If
the counterparty defaults and the value of the collateral declines, or if the
counterparty enters into insolvency proceedings, realization of the collateral
by a Portfolio may be delayed or limited.
 
OTHER -- Expenses that are directly related to one of the Portfolios are charged
directly to that Portfolio. Other operating expenses are prorated to the
Portfolios on the basis of relative net assets.
 
All organizational costs incurred in connection with the start up of the Fund
have been equally allocated to each Portfolio, except the Mid-Cap Value
Portfolio and are being amortized on a straight line basis over a period of
sixty months. In the event that any of the initial shares of each Portfolio are
redeemed by any holder thereof during the period that each Portfolio is
amortizing its organizational costs, the redemption proceeds payable to the
holder thereof will be reduced by the unamortized organizational costs in the
same ratio as the number of initial shares being redeemed bears to the number of
initial shares outstanding at the time of redemption.
 
USE OF ESTIMATES IN THE PREPARATION OF FINANCIAL STATEMENTS -- The preparation
of financial statements, in conformity with generally accepted accounting
principles, requires management to make estimates and assumptions that affect
the reported amount of assets and liabilities and disclosure of contingent
assets and liabilities at the date of the financial statements and the reported
amounts of revenue and expenses during the reporting period. Actual results
could differ from those estimates.

3.  INVESTMENT ADVISORY FEES, ADMINISTRATIVE FEES
    AND OTHER TRANSACTIONS WITH AFFILIATES
 
The Fund and the Adviser are parties to an Investment Advisory Agreement (the
"Advisory Agreement"). Under the terms of the Advisory Agreement, the Adviser is
paid a monthly fee at an annual rate of 0.85% of the average daily net assets of
the Growth II, Technology & Communications and Select 20 Portfolios' average
daily net assets, 1.00% of the Small Cap Value Portfolio's average daily net
assets, and 0.65% of the Large Cap Value Portfolio's average daily net assets.
In the interest of limiting expenses of the Portfolios, the Adviser has entered
into an expense limitation agreement with the Fund ("Expense Limitation
Agreement"). The Adviser has agreed to waive or limit its fees and to assume
other expenses of each Portfolio to the extent necessary to limit the total
annual operating expenses (expressed as a percentage of the Portfolio's average
daily net assets) to 1.20% of the average daily net assets of the Growth II,
Small Cap Value, Technology & Communications and Select 20 Portfolios and to not
more than 1.00% of the average daily net assets of the Large Cap Value
Portfolio. Reimbursement by the Portfolio of the advisory fees waived or limited
and other expenses paid by the Adviser pursuant to the Expense Limitation
Agreement during any of the two previous fiscal years may be made at a later
date when the Portfolio has reached a sufficient asset size to permit
reimbursement to be made without causing the total annual expense ratio of each
Portfolio to exceed the total operating expense percentages described above.
Consequently, no reimbursement by the Portfolio will be made unless: (i) a
Portfolio's net assets exceed $75 million; (ii) a Portfolio's total annual
expense ratio is less than that listed above, and (iii) the payment of such
reimbursement is approved by the Board of Directors on a quarterly basis. At
December 31, 1998, the amount of advisory fee waiver and reimbursement of third
party expenses by the Adviser subject to possible reimbursement were as follows:
 

Growth II Portfolio                             $134,577
Technology & Communications
 Portfolio                                      $ 93,603
Select 20 Portfolio                             $ 27,776
Large Cap Value Portfolio                       $ 47,374
Small Cap Value Portfolio                       $ 92,148

 
Pilgrim Baxter Value Investors, Inc. (formerly Newbold's Assets Management,
Inc.), a wholly-owned subsidiary of the Adviser serves as the sub-advisor to the
Large Cap Value Portfolio and the Small Cap Value Portfolio. For its services
provided pursuant to its Investment Sub-Advisory Agreement with the Adviser and
the Fund, Pilgrim Baxter Value Investors receives a fee from the Adviser at an
annual rate of 0.40%, and 0.65%, respectively, of the average daily net assets
of the Large Cap Value Portfolio and the Small Cap Value Portfolio. Pilgrim
Baxter Value Investors, Inc. receives no fees directly from the Large Cap Value
Portfolio or the Small Cap Value Portfolio.
 
PBHG Fund Services (the "Administrator"), a wholly-owned subsidiary of the
Adviser, provides the Fund with administrative services, including regulatory
reporting and all necessary office space, equipment, personnel and facilities.
For these administrative services, the Administrator receives a fee, which is
calculated daily and paid monthly, at an annual rate of 0.15% of the average
daily net assets of each Portfolio.
 
SEI Investments Management Corporation, a wholly-owned subsidiary of SEI
Investments Company, is the owner of all beneficial interest in SEI Investments
Mutual Funds Services (the "Sub-Administrator"). The Sub-Administrator is an
affiliate of the Fund's distributor and assists the Administrator in providing
administrative services to the Fund. For acting in this capacity, for the period
January 1, 1998 to April 30, 1998, the Administrator paid the Sub-Administrator
a fee at the annual rate of 0.07% of the average daily net assets of each
Portfolio with respect to the first $2.5 billion of the total average daily net
assets of (i) the Fund, and (ii) The PBHG Funds, Inc., another family of funds
managed by the Adviser, and a fee at the annual rate of 0.025% of the average
daily net assets of each Portfolio with respect to the total daily net assets of
(i) the Fund and (ii) The PBHG Funds, Inc. in excess of $2.5 billion. Effective
May 1, 1998 the Administrator pays the Sub-Administrator a fee equal to the
greater of $35,000 per Portfolio and $5,000 per additional class of shares or at
the annual rate of 0.04% of the first $2.5 billion of the average daily net
assets of (i) the Fund, (ii) PBHG Funds, Inc., and (iii) PBHG Advisor Funds,
Inc., other fund families managed by the Adviser (collectively known as the
"PBHG Fund Family"), 0.025% of the next $7.5 billion of the average daily net
assets of each portfolio in the PBHG Fund Family, and 0.02% of the average daily
net assets of each portfolio in the PBHG Fund Family in excess of $10 billion.
 
DST Systems, Inc. serves as the transfer agent and dividend disbursing agent of
the Fund. First Union National Bank, serves as the custodian for the Fund.
 
Effective January 2, 1998 the Fund entered into a shareholder servicing
agreement with PBHG Fund Services to provide shareholder support and other
shareholder account-related services. PBHG Fund Services has, in turn,
contracted with UAM Shareholder Service Center, Inc. to assist in the provision
of these services. For the year ended December 31, 1998, PBHG Fund Services was
paid $7,000 by the Growth II and Technology & Communications Portfolios, $6,875
by the Select 20 Portfolio and $6,750 by the Large Cap Value and Small Cap Value
Portfolios for transfer agent services.
 
Certain officers and directors of the Fund who are or were officers of the
Adviser, Administrator, Sub-Administrator and the Distributor received no
compensation from the Fund.

REPORT OF INDEPENDENT ACCOUNTANTS
TO THE SHAREHOLDERS AND BOARD OF DIRECTORS
  OF THE PBHG INSURANCE SERIES FUND, INC.:
 
In our opinion, the accompanying statements of net assets of the PBHG Growth II
Portfolio, PBHG Technology & Communications Portfolio and PBHG Select 20
Portfolio and the statements of assets and liabilities, including the schedules
of investments, of the PBHG Large Cap Value Portfolio and PBHG Small Cap Value
Portfolio 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 PBHG Insurance Series Fund, Inc., including the
PBHG Growth II Portfolio, PBHG Technology & Communications Portfolio, PBHG
Select 20 Portfolio, PBHG Large Cap Value Portfolio and PBHG Small Cap Value
Portfolio (the "Funds") at December 31, 1998, and the results of their
operations for the year then ended, the changes in their net assets for each of
the two years (or periods) in the period then ended and their financial
highlights for each of the periods presented, in conformity with generally
accepted accounting principles. These financial statements and financial
highlights (hereafter referred to as "financial statements") are the
responsibility of the Fund's management; our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these financial statements in accordance with generally accepted
auditing standards which require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits, which included confirmation of securities at December 31, 1998 by
correspondence with the custodian and brokers, provide a reasonable basis for
the opinion expressed above.
