       PBHG Growth II Portfolio


Dear Shareholder:

The PBHG Insurance Series Fund, Inc. -- PBHG Growth II Portfolio returned 10.14%
for the first half of 1998 compared with 11.87% for the Russell Mid-Cap Growth
Index. Most of the Portfolio's return was achieved during the first quarter.
During the second quarter, the Russell Mid-Cap Growth Index had a small negative
return while the Portfolio's results were up modestly as continued problems in
Asia raised investor concern and added to the market's volatility.

The technology, health care and consumer sectors performed strongly in the first
half of 1998 and made up nearly 60% of the Portfolio's holdings. Energy stocks
were weak due to lower oil and gas prices. Financials and service companies also
lagged the market. The top holdings of the Portfolio did especially well,
including J.D. Edwards, Ascend Communications and HBO & Company. America Online
and Uniphase also achieved large gains. Dura Pharmaceuticals, BJ Services and
ATMI all experienced lowered earnings expectations and as a result, their stocks
weakened during the first half.

The portfolio remains overweighted in service and technology stocks which
represent 22% and 33% of the total Portfolio, respectively. The service sector
includes solid waste management companies, information technology companies and
telecommunication service providers. The sector weightings mainly reflect our
growth company bias. Underweighted sectors include financials, basic industry
and capital goods stocks. The companies in the Portfolio, on average, continue
to grow earnings at rates above 50%.

It is important to point out that growth stocks -- small, mid and large cap --
outperformed their value counterparts year-to-date. While we are encouraged by
this recent reversal within the growth market, we continue to face a market that
favors large cap stocks over smaller stocks. This is occurring even though
earnings for mid-cap companies are accelerating, while earnings estimates for
large cap companies are decelerating. When the results for the second quarter of
1998 are available, we expect the small and mid-cap segments of the market will
post profit growth rates that surpass that of the large caps, making it the
fifth consecutive quarter of superior relative growth.

Sincerely,


/s/ Jeffrey A. Wrona

       PBHG Technology & Communications Portfolio

Dear Shareholder:


The PBHG Insurance Series Fund, Inc. -- PBHG Technology & Communications
Portfolio finished the period ended June 30, 1998 with a return of 12.30%,
compared with the benchmark Pacific Stock Exchange High Technology Index (PSE)
return of 19.26%. The Portfolio lagged the benchmark largely due to its
continued focus on smaller capitalization stocks, whose returns again trailed
those of larger stocks. For example, the Russell 2000, an index of smaller
capitalization stocks returned 4.91% over the same period, versus a return of
17.74% for the S&P 500.

Technology rallied strongly to begin 1998 and the PSE appreciated 19.17% in the
first quarter of the year, as investors became more confident that International
Monetary Fund intervention would help put a quick end to the "Asian Flu" that
hurt stocks so badly during the fourth quarter of 1997. By March 31, the PSE had
surpassed its previous highs reached before the Asian Crisis. However,
technology stocks took a breather in the early part of April as investors
nervously awaited quarterly earnings reports. This wait was a particular "nail
biter" because the first quarter was the first one that was fully impacted by
the Asian Crisis, which occurred more than halfway through the fourth quarter of
1997.

The earnings numbers released in April, while certainly not outstanding, were
stronger than investors had expected and technology stocks rallied. Technology
stocks took another hit later in the month as investors began to fear that a
strong economy would force the Federal Reserve to raise interest rates. However,
late April and early May brought favorable economic data that showed the economy
might be slowing on its own and it was off to the races again. By mid-May,
investors were again focusing on the ongoing issues in Asia. Japan's inability
to implement decisive policy to address its staggering economy and large amounts
of bad bank debt, coupled with poor data regarding Japanese economic growth
helped send the Yen spiraling downward. Fears that the Japanese weakness would
worsen the Asian Crisis and anecdotal signs of a slowing in European demand sent
U.S. stocks downward during the latter part of May. U.S. intervention to
stabilize the Dollar/Yen exchange rate and Japanese promises of economic reform
helped turn the market around and the PSE rallied strongly as the first half
came to an end. Despite all of this volatility, the PSE finished the second
quarter virtually unchanged from its level at the end of the first quarter.

Small capitalization companies have now lagged the broader market for the better
part of two years. The poor relative performance of small cap growth stocks has
occurred despite the fact that smaller company earnings growth has remained
excellent, while earnings growth at larger companies has slowed considerably. As
disciplined, earnings focused investors we will continue to invest in the
highest quality growth names. Therefore, while we remain open to including
larger companies in the portfolio, we feel that the best earnings growth (and
the best values) remain in the small cap part of the market.

Companies and sectors with a large exposure to Asian markets continued to suffer
during the first half of 1998. Specifically, semiconductor equipment,
semiconductor manufacturers and many wireless communications equipment companies
continued to experience lower orders and lessened visibility. The Portfolio
continues to be underweighted in these sectors, but we will continue to look for
opportunities to add to our positions as fundamentals improve.

       PBHG Technology & Communications Portfolio


Several of our technology service companies performed well as they continued to
benefit from the trend towards corporate outsourcing of information technology
service, continued spending related to the Year 2000 problem and rapidly
increasing billing rates. Particularly notable performers in this area were
Diamond Technology Partners, Tier Technologies and ECSoft Group. Other notable
performers during the quarter included internet service provider, Mindspring and
Citrix Systems, a provider of client-server software.


Among the disappointments was Advanced Fibre Communications, which pre-announced
lower than expected earnings due to the loss of a major customer and wireless
radio manufacturer, Remec, which fell prey to weaker end demand in Asia.


Going forward, we will continue to watch the situation in Asia closely. We also
monitor the continued strength of the U.S. economy, which has created tighter
labor markets and a high level of consumer spending. We believe that the events
in Asia will help slow our own economy down in the second half, lessening the
need for higher interest rates. While the problems in Asia have forced us to
become more selective, we remain excited about the technology sector, which
continues to be one of the most rapidly growing sectors of the U.S. economy.

       PBHG Select 20 Portfolio


Dear Shareholder:


The PBHG Insurance Series Fund, Inc. -- PBHG Select 20 Portfolio reached the
midway point of the current fiscal year on June 30, 1998, showing a total return
of 31.11% since January 1, 1998. Over this same time period, the S&P 500 Index
and Russell Top 200 Growth Index produced total returns of 17.74% and 23.21%,
respectively. The Portfolio's outperformance relative to the S&P 500 was fairly
consistent over the period, besting the Index in 5 of the 6 months. The month of
May was the exception, where we underperformed the Index by roughly 50 basis
points, in the only negative return month so far this year in the Index or in
the Select 20 Portfolio. There were no negative fundamental developments
afflicting our holdings in May, but we did have two stocks, radio station
operator Chancellor Media and data storage systems vendor EMC Corp., that
declined in price over 10% for the month, which weighted down the overall
performance of the Portfolio.

A review of performance by industry sector shows that technology was by far our
biggest contributor, accounting for roughly 59% of the year-to-date return.
Within this group, the best individual performers were America Online (+132%),
Dell Computer (+121%), and Lucent Technologies (+108%). The second biggest
sector contribution came from the services sector, which accounted for about 18%
of the Portfolio's total return. In this sector, the best performers were
Worldcom (+60%) and Clear Channel Communications (+37%). We continue to maintain
large positions in each of these companies, as we believe they remain extremely
well positioned within their respective markets for continued superior growth.

Our only negative return sector over the period was energy. Fortunately, the
impact has been negligible, as we exited this sector completely in January and
have resisted the temptation to re-enter. By far our worst individual performer
in the period was Cendant Corp., which claimed to suddenly discover "accounting
irregularities" at a recently acquired business. Despite facing a 49% negative
hit by selling the stock around the time of the announcement, we felt this was
the most prudent course of action given the uncertain outcome of additional
independent audits of Cendant's accounting practices. The only holding still in
the Portfolio that produced a negative return over the six month period was
rehabilitation services provider HealthSouth (-4%). Here, we believe the share
price weakness did not reflect any deterioration in business fundamentals,
rather the stock suffered from professional arbitrage activity related to
HealthSouth's planned purchase of publicly-traded National Surgery Centers, the
largest independent operator of "stand-alone" outpatient surgery centers.

As we enter the second half of 1998, we remain constructive on the large cap
portion of the equity market despite numerous influences, both positive and
negative. Among the negatives, valuations are at historical highs which
heightens short-term risk. In this regard, however, we take some comfort in a
very supportive interest rate environment and an economy that keeps humming
along. The other key potential negative is the ultimate influence on the U.S.
economy of the collapsed Asian economies. We have structured the Portfolio such
that our holdings have negligible financial exposure in the region and, in some
cases, may actually benefit from the availability of cheaper goods and/or labor.
On the positive side, investors continue to buy U.S. equity mutual funds and
foreign investors are shifting their capital increasingly to the U.S., as they
look for a safer haven following the damage incurred in many emerging markets.
This represents additional "buying power" that should help sustain stock
valuations. We also believe that a modest slowdown in U.S. economic growth
caused by the Asian situation would not necessarily be a bad thing for U.S.
investors.

Specifically, it should help keep interest rates and inflation in check, which
is not only positive for investors but also for those companies (like the ones
we strive to own) that are investing in their businesses in order to take
advantage of growth opportunities.

Crosscurrents like these are what keep "big picture" strategists employed.
Frankly, we don't envy them. We much prefer to spend our time seeking out and
investing in just a few high-quality, high-growth companies. And with supportive
shareholders like you, we will continue to do just that.

       PBHG Large Cap Value Portfolio


Dear Shareholder:

The stock market rallied strongly again in the first half of 1998. The PBHG
Insurance Series Fund, Inc. -- PBHG Large Cap Value Portfolio returned 15.15%
versus a total return of 12.17% for the Russell 1000 Value Index and a total
return of 17.74% for the S&P 500. We are very satisfied with our start in 1998,
but would caution all investors that future stock market returns are unlikely to
be as robust as recent results.

Market Overview

The widely reported outbreak of "Asian Contagion" did not slow the U.S. economy
as expected in the first quarter of 1998. However, the domestic impact has been
notable in May and June. Many companies have preannounced disappointing profits
for the second quarter, and the present stock market has no patience for
negative surprises. While volatility is unsettling over the near-term,
exaggerated movements in stock prices typically create opportunities for
investors, and we are working hard to lay the foundation for solid results in
the months ahead. We would also note that the ongoing crisis in Asia and
resulting pressure on profits in the U.S. should encourage our Federal Reserve
to maintain an even-handed stance on monetary policy.

Our fundamental long-term view of the large cap value sector of the market is
positive. In the U.S., macroeconomic conditions are extremely favorable for
investors: Inflation is low, long-term interest rates are declining and the
Federal Budget is in balance for the first time in 20 years. The uncertain
outlook for profits will continue to produce occasional disappointments for
equity investors, but we continue to believe that the stocks of companies that
report good earnings will perform very well in this low interest rate
environment.

Investment Strategy

The major shift in our investment strategy has been a significant increase in
our commitment to financial stocks. The problematic earnings environment
developing for technology and industrial companies has caused our stock
selection to gravitate towards companies in other areas which are more likely to
report strong profit comparisons. Those companies are increasingly concentrated
in the financial sector. Recent investments in this area include PMI Group,
First Chicago NBD, Chase Manhattan, and North Fork Bancorp. These stocks offer
an attractive combination of below-average P/E multiples, good growth
characteristics and strong near-term business dynamics. We expect these holdings
to provide good returns in a benign interest rate environment, and will report
the results to you in our next shareholder letter.

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:

The stock market rallied strongly again in the first half of 1998. The PBHG
Insurance Series Fund, Inc. -- PBHG Small Cap Value Portfolio returned 9.92%
versus a total return of 4.91% for the Russell 2000 index. We are pleased to be
off to a good start in 1998, and are looking forward to serving you for the
remainder of the year.

Market Overview

The widely reported outbreak of "Asian Contagion" did not slow the U.S. economy
as expected in the first quarter of 1998. However, the domestic impact has been
notable in May and June. Many companies have preannounced disappointing profits
for the second quarter, and the uncertainty surrounding the earnings outlook
precipitated a sharp correction in the small cap segment of the stock market.
While volatility is unsettling over the near-term, exaggerated movements in
stock prices typically create opportunities for investors, and we are working
hard to lay the foundation for solid results in the months ahead. We would also
note that the ongoing crisis in Asia and resulting pressure on profits in the
U.S. should encourage our Federal Reserve to maintain an even-handed stance on
monetary policy.

Our fundamental long-term view of the small cap market remains favorable. In the
U.S., macroeconomic conditions are extremely favorable for investors: Inflation
is low, long-term interest rates are declining and the Federal Budget is in
balance for the first time in 20 years. The uncertain outlook for profits will
continue to produce occasional disappointments for equity investors, but we
continue to believe that the stocks of companies that report good earnings will
perform very well in this low interest rate environment. Furthermore, with the
continued underperformance of small cap stocks versus large stocks, the small
stock sector of the equity market offers an unusual abundance of investment
values. When investor sentiment eventually turns more positive towards small cap
stocks, your portfolio should be well-positioned to benefit.

Investment Strategy

The major shift in our investment strategy has been a significant increase in
our commitment to financial stocks. The problematic earnings environment
developing for technology and industrial companies has caused us to gravitate
towards companies in other areas which are more likely to report strong profit
comparisons. Those companies are increasingly concentrated in the financial
sector. Recent investments in this area include CMAC Investment Corp., Pacific
Bank, Raymond James Financial, UST Corp. and City National. These stocks have an
attractive combination of below-average P/E multiples, good growth
characteristics and strong near-term business dynamics. We expect these holdings
to provide good returns in a benign interest rate environment, and will report
the results to you in our next shareholder letter.

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


Sincerely,

NOTES TO FINANCIAL STATEMENTS
As of June 30, 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
Small Cap Value Portfolio (the "Small Cap Value Portfolio"), the PBHG Large Cap
Value Portfolio (the "Large Cap Value Portfolio"), the PBHG Select 20 Portfolio
(the "Select 20 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 nondiversified
management investment company. The financial statements presented herein do not
include the Large Cap Growth Portfolio, which is presented separately, or the
Mid-Cap Value Portfolio, which has not yet commenced operations. 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 June 30, 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:

</TABLE>
 
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 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. 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 the 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, 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, respectively. 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
June 30, 1998, the amount of advisory fee waiver and reimbursement of third
party expenses by the Adviser subject to possible reimbursement were as follows:

</TABLE>
 
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, the
Administrator pays 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 will pay
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 0.040% of the
first $2.5 billion of the average daily net assets of (i) the Fund, (ii) PBHG

the Adviser (collectively known as the "PBHG Fund Family"), 0.025% of the next

Family, and 0.020% 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 Bank, N.A. serves as the custodian for the Fund.
