PBHG Growth II Portfolio



Dear Shareholder:

The PBHG Insurance Series Fund, Inc. -- PBHG Growth II Portfolio ended an
abbreviated first fiscal year on December 31, 1997. In its first eight months of
operation, the fund generated an aggregate total return of 7.50%, compared with
the benchmark Russell Mid-Cap Growth Index return of 24.13%. Performance in this
initial period was buffeted by a number of factors, not all of which were market
related. For example, results in the first month of the fund's existence were
constrained by the high proportion of cash in the portfolio, a consequence of
being in a start-up mode when large (relative to a small base) daily cash
inflows can create an "under-invested" portfolio. During May, the Russell
Mid-Cap Growth Index returned 8.96% while the Growth II Portfolio returned only
0.90%.

Once we reached a more fully invested position in June, we made up some lost
ground and essentially performed in line with our benchmark through mid-October.
Mid-Cap growth stocks were coming out of a severe relative valuation correction
vis-a-vis their large capitalization brethren in the Standard & Poor's 500
Index, an adjustment which had begun in May of 1996. Now, with year-over-year
earnings growth apparently slowing somewhat in the large cap, stable growth
area, the attraction of smaller company growth issues was moving to the fore.
Economists remained confident that real economic growth would continue at a
moderate rate, and with reported rates of inflation still quite low and the Fed
unwilling to follow up on its initial "pre-emptive" rate hike, the bond market
extended its rally. The outlook seemed quite promising.

But surprises being what they are, the markets were caught off guard by the
currency crisis in Asia. Asian currencies -- already weak -- simply collapsed,
victims of inflated economies and speculation. The rush to convert holdings into
U.S. dollars made it difficult to conduct cross-boarder business and called into
question the ability of the area to raise capital and support its expected
growth. Technology companies and a good many of our oil service companies do a
significant amount of business -- both in terms of manufacturing and final sales
- -- in the area, and the market's retribution was swift and severe. Energy issues
were further impacted by an unusually warm winter and the prospect of renewed
oil sales from Iraq. Investors were relatively quick to return to the large cap
"stable growth" issues which dominate the Dow Jones and S&P 500 Indexes, but the
year closed with many smaller company issues languishing in uncertainty.

Looking ahead into 1998, we expect a challenging environment for equities. The
uncertainty created by the "Asian Contagion" and its potential impact on our
economy will not be known, indeed cannot be known, for some time. With the
resultant uncertainty pervading the financial markets, we would expect
volatility to continue to be a market watchword. Despite these crosscurrents, we
remain committed to our individual company focus and our belief that superior
relative earnings growth should eventually lead to relative stock valuation
premiums. Our portfolio characteristics, with position weighted three-to-five
year historic revenue and earnings growth of 26% and 41%, respectively, and
latest twelve-month earnings growth of 62%, compare quite favorably with our
benchmark. We believe that these characteristics will serve the Portfolio well
in 1998 and beyond.

PBHG GROWTH II PORTFOLIO



         THE PILGRIM BAXTER DISCIPLINE
         As part of our annual review, it seems worthwhile to review our
         investment philosophy. Our investment philosophy and methodology remain
         the same through both up and down cycles. We continue to seek out and
         invest in the highest quality, fastest growing companies we can find
         within the capitalization parameters established for the Portfolio. As
         long-time managers following this style, we are pleased to report that
         we believe there is currently no shortage of very good companies,
         quality management, and strong ideas in which to invest.

         We continue to find most of our investments in the technology, health
         care, consumer, and service sectors -- those industries in which
         company and stock price performance have been most remarkable over the
         last several years. As a result, we often find our portfolios highly
         concentrated in particular sectors of the market at different times. We
         tend to hold significant positions in industries while their growth
         curves are steepest -- either due to technological improvement, an
         under-supply of new or key industry products, or perhaps consolidation
         among competitors. Our companies are most often characterized by rapid
         unit growth and problem-solving capacity for their customers. This
         concentration can contribute to very favorable returns while the
         companies scale the growth curve and there aren't enough shares to go
         around Wall Street. But the ride down may be equally steep, once
         investors get a hint that the growth may be slowing. Our disciplined
         investment process identifies and drives us toward those companies
         whose fortunes are meeting or exceeding operating expectations, and
         away from those whose business opportunities are flagging.

         Our disciplined investment approach has always and will continue to
         strictly follow a "bottom-up" approach, i.e., focusing on individual
         companies -- their fundamental business characteristics and the
         sustainability of their growth rates. We don't make market forecasts
         and don't use others' "big picture" forecasts to guide our investment
         process. Finally, we strive to be fully invested at all times, since we
         believe attempting to "time" the market is also not a productive
         endeavor.

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

         Sincerely,

PBHG Large Cap Value Portfolio

Dear Shareholder:

The PBHG Insurance Series Fund, Inc. -- PBHG Large Cap Value Portfolio ended an
abbreviated fiscal year on December 31, 1997. In its first two months of
operation, the Portfolio generated an aggregate total return of 4.30% versus
total return of 7.47% for the Russell 1000 Value index. Although we are off to a
sluggish start, we should note that two months are a very short period in
investing. Based on the plentiful number of good investment ideas meeting our
criteria, we are quite optimistic regarding the Large Cap Value Portfolio's
prospects for the coming year.


MARKET OVERVIEW
Despite the widely reported outbreak of "Asian Contagion" in the fall, the U.S.
stock market provided positive returns in the last two months of 1997. The
financial panic in Asia did add to volatility in our markets in November and
December, and our markets face an additional element of uncertainty moving
forward into 1998. However, it is also true that the Federal Reserve appears
much less likely to tighten monetary policy in the wake of the Asian financial
crises. Here in the U.S., given our low inflation, moderate interest rates and a
Federal Budget in balance for the first time in 20 years, we believe the
investment outlook is quite positive.

Our fundamental view of the large cap value sector of the market is also
favorable. Despite the strong overall stock market of the past 3 years, the
volatility and irrational psychology of many investors has left many large cap
value stocks lagging behind at very reasonable valuations. Among our notable
holdings, Ford is valued at only 9.3 times estimated 1998 earnings, and American
Airlines, Santa Fe International, Morgan Stanley/Dean Witter Discover, Eaton and
Dow Chemical all trade for 14 times or less 1998 earnings per share. While the
S&P 500 may be close to fair value at approximately 19.8 times estimated 1998
earnings per share, we think our Large Cap Value Portfolio is comprised of
stocks which are substantially undervalued.


THE PILGRIM BAXTER VALUE DISCIPLINE
Since this is our first annual report to our shareholders, it seems worthwhile
to review our investment approach. Our investment philosophy and methodology
remain the same regardless of the stock market environment. We stay fully
invested at all times and do not try to "time" the market. Our value approach is
a rational and disciplined approach based on a multi-factor model that allows
for intelligent trade-offs between the valuation of a stock, and the growth rate
and business dynamics of the underlying enterprise. We work hard to create a
portfolio of large cap stocks with a below-average P/E ratio, good growth
characteristics and business dynamics which are sharply above-average. As noted
above, Ford, American Airlines, Santa Fe International, Morgan Stanley/Dean
Witter Discover, Eaton and Dow Chemical are all high-quality companies selling
at reasonable valuations which exemplify our approach. This strategy has worked
well for us in the past and we are optimistic that it will work well in the
future.

         Our disciplined approach is predominantly a "bottom-up" stock selection
         approach, although at times our best ideas will cluster in a specific
         sector or industry, leading us to overweight that area. We do not
         engage in futile attempts to forecast the markets and we refrain from
         using others' "big picture" forecasts to guide our investment process.
         Essentially, we believe that Ezra Solomon, an economist, had it exactly

         to make astrology respectable".

PBHG Small Cap Value Portfolio


Dear Shareholder:

The PBHG Insurance Series Fund, Inc. -- PBHG Small Cap Value Portfolio ended an
abbreviated fiscal year on December 31, 1997. In its first two months of
operation, the fund generated a total return of 4.80% versus a total return of
1.09% for the Russell 2000 Index. We are pleased to be off to a good start, and
are looking forward to serving you for a full year in 1998.

Despite the widely reported outbreak of "Asian Contagion" in the fall, the U.S.

investment outlook is quite positive.

Our fundamental long-term view of the small cap market is also favorable.
Despite the strong overall stock market of the past 3 years, many small cap
stocks still offer good earnings growth prospects at reasonable multiples of
earnings. Furthermore, large cap companies have now outperformed small companies
in the stock market for 4 consecutive years, and we believe the performance
cycle will turn back in favor of small companies in the not-too-distant future.
When that time comes, we would expect our Small Cap Value Portfolio to perform
notably better than the large cap S&P 500 index.

PBHG Technology & Communications Portfolio

Dear Shareholder:

The PBHG Insurance Series Fund, Inc. -- PBHG Technology & Communications
Portfolio ended its abbreviated first fiscal year on December 31, 1997. In its
first eight months of operation, the Portfolio generated a total return of
4.10%, compared with the benchmark Pacific Stock Exchange High Technology Index
return of 16.39%. Performance in this initial period was somewhat constrained by
the high proportion of cash in the first two months, which generally results
from being in a start-up mode as large (relative to the small base) daily cash
inflows can create an "under-invested" portfolio. This was particularly true
early in the month of May, when the market was rising rapidly. Over the course
of the summer months, smaller capitalization technology stocks began to
outperform and the momentum of the Portfolio remained strong up until early
October. Intel reported disappointing results on October 14th and the "Asian
Contagion" hit full swing over the following two weeks, leaving the Pacific
Stock Exchange High Technology Index off 17.3% for this fourteen day period. The
Southeast Asian crisis continued to deteriorate through year-end. This, coupled
with pre-release earnings disappointments from Oracle, Seagate, Cabletron, 3Com,
and Electronics For Imaging, created poor fourth quarter results for both the
Portfolio and the relevant benchmarks.

The Portfolio's preference for higher growth, smaller capitalization companies
contributed to its under-performance in 1997. The Portfolio's price earnings
ratio fell by roughly 25% over the fiscal year, despite pristine financial and
operating characteristics of the underlying companies. At December 31st, the
position weighted latest twelve-month earnings growth on our invested assets was
68%, with a 21.3% return on equity.

Companies and sectors with the greatest exposure to Southeast Asia, such as
those companies exporting a large percentage of their products to the region,
suffered the largest sell-off in the final months of the year. Semiconductor
(Microchip, Integrated Circuits), semiconductor equipment (KLA-Tencor, Kulicke &
Soffa, Speedfam, ADE Corporation) and telecommunication (Teledata, Remec,
Powerwave) stocks declined significantly more than the Portfolio as a whole.
Electronics For Imaging stumbled as they experienced inventory drawdowns from
their Japanese customers.

The service subsector provided the best returns for the fiscal year due to their
recurring revenue models which typically lead to strong backlogs and highly
predictable and sustainable earnings growth. These companies tend to leverage
technology as opposed to creating it. They continue to benefit from the year
2000 conversion, the internet and intranet, electronic commerce, and the
shortage of professional information technology specialists in the U.S. and
Europe. The business remains outside the Southeast Asian geography and the
stocks have tended to maintain value in periods of uncertainty. Cambridge
Technology Partners, Information Management Resources, Keane, Intelligroup and
ECSoft Group had strong results for the fiscal year.


THE 1998 OUTLOOK
As we approach 1998, the "Asian Contagion" has become the focal point on the
investment outlook. The recent developments in Asia have added a larger dose of
uncertainty

         to the global economic expansion and the deflationary impact of the
         crisis on world trade. According to Greg Smith, strategist at
         Prudential Securities, the issue will essentially lie in how
         "governments apply corrective policy medicine to support their
         currencies and eventually set the base for improved economic growth."

         While the Asian situation will contribute to near-term financial market
         volatility, the focus will clearly return to the solid domestic
         fundamentals in the United States. We believe small cap technology
         stocks are showing their best relative earnings strength in several
         quarters against the larger multinational technology issues. Superior
         relative earnings growth should eventually lead to a relative valuation
         premium. The Portfolio is clearly building positions in holdings with
         less exposure to the affected emerging markets in favor of companies
         with outstanding earnings visibility and sustainability of future
         growth rates. Recent U.S. capital spending surveys still predict
         healthy spending levels in 1998, particularly in the information
         technology service, networking, software and medical device subsectors.
         With the power of superior relative earnings growth and historically
         low relative valuations, we remain positive on the sector and the
         Portfolio's opportunity for 1998.

         Sincerely,

PBHG Select 20 Porfolio

Dear Shareholder:

The PBHG Insurance Series Fund, Inc. -- PBHG Select 20 Portfolio ended its
abbreviated first fiscal year on December 31, 1997 with an aggregate total
return of 0.30% since its inception on September 26, 1997. Over this same time
period, the Russell Top 200 Growth Index produced a total return of 3.05% and
the S&P 500 Index produced a total return of 3.93%. The underperformance
relative to this benchmark can largely be attributed to the Portfolio's
"start-up" mode that existed during this time period particularly in the first
two months of operation. A small asset base that made effective trading
challenging coupled with relatively high daily cash inflows placed the Portfolio
in an underexposed position which is always detrimental to performance in a
rising equity market. Had the market steadily declined during this initial
period, we would have looked very smart. By the beginning of December, the
Portfolio was approaching a more normal situation (the cash position was brought
below 20% for the first time) and in December we experienced a gain of 3.83%
versus an S&P 500 Index gain of 1.57%.

Our best performers over the Portfolio's short initial period included
enterprise software provider PeopleSoft (+20.3%), billboard and radio station
operator Clear Channel Communications (+13.5%), on-line service provider America
OnLine (+11.9%), consumer services firm Cendant (+11.7%), and mortgage insurer
MGIC Investment (+10.7%). Our worst performers included communications firm
WorldCom (-8.7%), PC maker DELL Computer (-6.4%), and diversified energy
services company Schlumberger (-4.5%). Despite the short-term declines we remain
positive on the longer-term fundamental business outlook for each of these three
companies and we plan to retain them at this time.

Since this is our first opportunity to communicate with Select 20 Portfolio
shareholders it seems worthwhile to review the Pilgrim Baxter & Associates, Ltd.
disciplined investment approach. Our investment philosophy and methodology
remain the same through both up and down cycles. We constantly seek out and
invest in the highest quality, fastest growing companies we can find within the
capitalization parameters established for the Portfolio. As long-time managers
following this style, we are pleased to report that there is currently no
shortage of very good companies with quality management and strong ideas in
which to invest. We tend to find the best investment ideas in the fast-growing
technology, healthcare, consumer and business services sectors. Since the
Portfolio has no sector constraints it may from time to time become highly
concentrated in one or more of these sectors as we strive to own the 20 best
large cap ideas regardless of industry. (At year end our largest sector exposure
was technology at 35%). Our companies are most often characterized by rapid unit
growth and by problem solving capacity for their customers. These
characteristics, among others, are important in creating the potential for
companies to exceed operating expectations. Our disciplined investment process
drives us toward these companies and away from those whose business
opportunities are waning. Our focused approach has always and will continue to
strictly follow a "bottom-up" approach, i.e. analyzing individual companies --
their fundamental business characteristics and the sustainability of their
growth. We don't make market forecasts and we don't use others' "big picture"
forecasts to guide our investment process. Finally, we strive to be fully
invested at all times, since we believe attempting to "time" the market is not a
productive endeavor.

PBHG SELECT 20 PORTFOLIO


         Looking ahead into 1998 we expect a more challenging environment for
         equities in general and don't expect a 4th straight year of 20+% gains
         in the major indices. What investors dread most is uncertainty, and the
         ultimate impact of the "Asian Contagion" on our economy will not be
         known for some time. While trying to divine the bottom line outcome,
         one can come up with as many possible positive influences as negatives.
         For example, concerns that a flood of cheap Asian imports will force
         U.S. manufacturers to cut prices and thereby lower profit margins are
         counterbalanced by the argument that if the Asian situation leads to a
         slowdown in the U.S. economy because of slowing exports to the region,
         then interest rates should fall leading to lower corporate interest
         expenses -- an offset to lower profit margins. Likewise, one can argue
         that since U.S. firms manufacture more product in southeast Asia for
         sale elsewhere in the world than they manufacture in the U.S. and sell
         to Southeast Asia markets, the dramatic currency devaluations in
         Southeast Asia with the resulting decline in labor costs may prove to
         be a net positive for U.S. firms.

         We think debates such as these will rage well into 1998 with no
         definitive answers becoming evident, possibly even by year end. With
         the resultant uncertainty pervading the markets, we expect continued
         high short-term volatility in the U.S. equity markets for the
         foreseeable future. Despite all the confusing crosscurrents, we remain
         committed to our individual company focus and our belief that superior
         relative earnings growth should eventually lead to relative stock
         valuation premiums. The Select 20 Portfolio approach of concentrating
         on a limited number of high-quality, fast-growing, large companies may
         generate substantial short-term volatility, but if we select the right
         stocks the higher short-term risk may be rewarded with superior longer
         term performance.

         Sincerely,


         /s/ James D. McCall

PBHG INSURANCE SERIES FUND, INC.
- --------------------------------------------------------------------------------

NOTES TO FINANCIAL STATEMENTS
As of December 31, 1997
 
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 six Portfolios: the PBHG
Growth II Portfolio (the "Growth II Portfolio"), the PBHG Large Cap Growth
Portfolio (the "Large Cap Growth Portfolio"), the PBHG Small Cap Value Portfolio
(the "Small Cap Value Portfolio"), the PBHG Large Cap Value Portfolio (the
"Large Cap Value Portfolio"), the PBHG Technology & Communications Portfolio
(the Technology & Communications Portfolio) and the PBHG Select 20 Portfolio
(the "Select 20 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 nondiversified management investment company. The financial
statements presented herein do not include the Large Cap Growth Portfolio which
is 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,
1997, the following percentage of outstanding shares of the portfolios were held
by the separate accounts of the number of participating Insurance Companies
listed below:

  contribution for the first full year of portfolio operations.
 
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 on each business day. If there is no
such reported sale, these securities and unlisted securities for which market
quotations are not readily available, are valued at the mean between the most
recent bid price and asked 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 or accumulated net realized gain, as appropriate, in
the period that the differences arise.
 
Accordingly, the following permanent difference as of December 31, 1997,
attributable to a net operating loss which for tax purposes is not available to
offset future income, has been reclassified to the following account:
 
                                                  Paid-in-Capital
                                                  ---------------
Growth II Portfolio............................        2,982
 
This reclassification has 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 each Portfolio's assets, less
liabilities, by the number of shares outstanding.
 
REPURCHASE AGREEMENTS -- Securities pledged as collateral for repurchase
agreements are held by the custodian bank until the respective agreements
mature. Provisions of the repurchase agreements and procedures adopted 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 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 Portfolios 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, respectively. Reimbursement by each 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 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, 1997, the amount of advisory fee waiver and reimbursement of third
party expenses by the Advisor subject to reimbursement were as follows:
 

Growth II Portfolio                                  $84,484

REPORT OF INDEPENDENT ACCOUNTANTS
 
TO THE SHAREHOLDERS AND BOARD OF DIRECTORS
  OF PBHG INSURANCE SERIES FUND, INC.:
 
We have audited the statements of net assets of the PBHG Growth II and PBHG
Select 20 Portfolios, and the statements of assets and liabilities, including
the schedules of investments, of the PBHG Large Cap Value, PBHG Small Cap Value,
and PBHG Technology & Communications Portfolios of PBHG Insurance Series Fund,

financial statements and financial highlights are the responsibility of the
Fund's management. Our responsibility is to express an opinion on these
financial statements and financial highlights based on our audits.
 
We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of investments owned as of
December 31, 1997 by correspondence with the custodian and brokers. An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.
 
In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
PBHG Growth II, PBHG Large Cap Value, PBHG Small Cap Value, PBHG Technology &
Communications and PBHG Select 20 Portfolios of PBHG Insurance Series Fund, Inc.
as of December 31, 1997, and the results of their operations, changes in their
