Re:  Penn Mutual Variable Life Account I
     File Nos. 33-54662 and 33-87276
     -------------------------------

Ladies and Gentlemen:

On behalf of The Penn Mutual Life Insurance Company (the "Company") and Penn 
Mutual Variable Life Account I (the "Account"), we present herewith for filing 
pursuant to Rule 30b2-1 under the Investment Company Act of 1940, as amended, 
copies of the Semi-Annual Reports to contract owners of the Account for the six 
months ended June 30, 1997.

Although the attached Semi-Annual Reports were timely mailed to contract owners 
in August, we recently learned that filing of the Reports with the Securities 
and Exchange Commission was overlooked. We have discussed this with the 
Company's management and have been assured that this will not happen again.

If you have any questions regarding this filing, please do not hesitate to 
call the undersigned at (215) 963-5913.

Very truly yours,

TO OUR VARIABLE LIFE INSURANCE CONTRACTHOLDERS:
 
  I am delighted to present the Semi-Annual Reports of Penn Series Funds, Inc.,
Neuberger & Berman Advisers Management Trust, American Century Variable
Portfolios, Inc., Fidelity Investments Variable Insurance Products Fund and
Variable Insurance Products Fund II, and Morgan Stanley Universal Funds, Inc.
for the six month period ending June 30, 1997.
 
  The first 6 months of 1997 were not too much different from what we've been
seeing in the equity markets for the previous 2 years--lots of volatility, but
with a dramatic move upward.
 
  As of June 30, the market as measured by the S&P 500 was up 20.59%, and the
Russell 2000, a measure of small cap stock performance was up 9.31%.
 
  But this bull market trend was interrupted by a near 10% correction amid
fears of continued increases in interest rates by the Federal Reserve to cool
an economy that seemed overheated. However, as the second quarter progressed,
economic reports signaled a slow down from the first quarter's rapid pace, and
inflation remained in check. Corporate earnings were up over 10% and the market
took off once again, rising more than 20% in May and June.
 
  So at this point the "pillars" of the stock market are very solid--benign
inflation and interest and strong corporate earnings. The $64,000 question of
course is, "With the Dow above 8000 and price-earnings ratios above 20, is the
market valuing all of this good news too highly?"
 
  As we've discussed before, if you are a long term investor, try not to be too
influenced with the short term twists and turns of the stock market. Rather,
working with your financial planner, apply solid risk reduction techniques such
as diversification and regular rebalancing of your portfolio to meet your long
term needs.
 
  Penn Mutual's variable products now offer more diversification possibilities
than ever before with 4 new additions to our family of funds:
 
    ICMI/Robertson Stephens Emerging Growth Fund
    Morgan Stanley Emerging Markets Equity (Int'l) Portfolio
    Neuberger & Berman AMT Partners Portfolio
    Fidelity Investments VIP II Index 500 Portfolio
 
  Your CORNERSTONE VUL policy is designed to help you maintain a steady, long-
term approach to investing. It brings the experience and expertise of various
investment advisers to help you build a financial plan that best suits your
individual needs. And we encourage you to work with your financial planner to
take full advantage your policy's features and investment choices.
 
  Percentage changes in accumulation unit values of each of the variable
accounts offered under CORNERSTONE VUL for the six month period ending June 30,
1996 are set forth in the accompanying table.
 
  Management discussions of the performance of the funds are included in the

MANAGEMENT DISCUSSION OF FUND PERFORMANCE
 
QUALITY BOND FUND
 
Interest rates reversed course in the second quarter, falling 35-40 basis
points and retracting much of the upward surge in rates experienced in the
first three months of 1997. A sharp deceleration in economic growth led by a
drop-off in consumer spending, coupled with surprisingly low inflation data has
reduced anxieties about further Federal Reserve rate hikes and led to bond
market improvement.
 
  The estimates for second quarter growth range from 1-2%, a dramatic decline
from the 5.8% growth in the first quarter. Consumer spending has inexplicably
changed course, dropping off just as most market observers had assumed
continued growth. Conventional wisdom has it that consumer spending will
rebound due to 1) strong labor market with low unemployment, 2) high consumer
confidence 3) firm income levels and finally 4) rising wealth levels arising
from a soaring stock market. A firm rebound in domestic consumption will in all
likelihood lead to an initial sell-off in the bond market as most market
participants will look for renewed inflationary pressures and further monetary
tightening.
 
The greatest surprise for this economic cycle has been the absence of inflation
pressures. In fact, the producer price index posted its fifth straight monthly
decline in May, a feat not seen since 1952. It is this development that has
stayed the hand of the Federal Reserve this cycle and allowed this economic
cycle (which began in March, 1991), to persist well beyond the post war average
of 4.5 years.
 
  This low level of inflation also creates an environment where bond yields are
very attractive whenever they reach or approach 7%. With inflation at 2-3%,
real yields of 4-5% are extremely high by historical standards. Indeed, bond
returns have been historically very good when bonds are purchased with 5% real
yields. The second quarter offered another opportunity to purchase bonds with
high real yields which we took advantage of.
 
  Another key consideration in addressing the outlook for the domestic bond
market is the forecasts for economic growth overseas. In this economic cycle
the foreign economies, notably Japan, have been severely hampered by structural
problems. In Japan, the problems are rooted in a difficult banking environment,
itself a hangover from the excesses of the 1980's. Monetary policy in Japan,
the number two economy in the world, has been dramatically accommodative. Short
term rates have been driven down to 0.5%. In Europe, the effort to create a
unified currency has led to severely restrictive fiscal policies, slowing their
economies and resulting in highly stimulative monetary policies as well.
 
  This weakness in the major foreign economies has reduced inflationary
pressures and created liquidity that in many cases has been invested here in
the US. A reversal in these highly accommodative monetary policies should have
significant implications to our fixed income markets. We do not see changes
occurring in the near future.
 
  Currently, our position is long relative to our benchmark. We extended the
portfolio as rates moved above 7% in the long bond. In addition, we moved more
aggressively into corporate bonds as spreads widened in March and April.
 
  Performance for the quarter was fair as the net result of +3.64% for the
Quality Bond Fund exceeded the Salomon Brothers Broad Investment Grade Index of
3.60%. Note that beginning in the second quarter our benchmark measurement
index changed to the Salomon Index vs the Lipper Bond averages. Year to date
figures are misleading due to differences in duration requirements between the
Salomon Index and the Lipper averages.

MANAGEMENT DISCUSSION OF FUND PERFORMANCE
 
HIGH YIELD BOND FUND
 
The stars were aligned for the high-yield bond market during the past six
months. Virtually all the principal influences on this market were positive if
not exuberant, especially the U.S. economy and the market's own fundamentals.
The rise in interest rates that dampened returns on high-quality bonds in the
first quarter was not a problem for the credit-sensitive, high-yield market. As
a result, high-yield bonds significantly outperformed high-quality bonds for
the six months ended June 30.
 
MARKET ENVIRONMENT
 
Many of the same factors that drove stocks higher fueled the rise in high-yield
(junk) bond prices. Topping this list were the continued and largely unexpected
strength in corporate earnings and the economy's 5.8% annualized growth rate in
the first quarter--roughly double the trend rate since the current upturn began
in 1991. In an attempt to cool this pace and preempt a rise in inflation, the
Federal Reserve raised the federal funds rate (from 5 1/4% to 5 1/2%) for the
first time since 1995, and interest rates rose across the yield curve. However,
stocks and high-yield bonds, which typically are driven by economic growth and
corporate earnings expectations, recovered quickly and forged ahead.
 
  High-yield bonds also benefited from extremely strong demand relative to the
supply of issues. Cash flow into retail high-yield mutual funds was heavy; the
number of institutional investors allocating assets to this market sector
continued to rise; and structured securities called collateralized bond
obligations (CBOs) absorbed billions of dollars worth of high-yield bonds. On
the supply side, new issues appeared at a steady clip, particularly from
smaller companies. Nevertheless, many potential high-yield bond issuers have
elected to refinance existing bonds through a growing number of attractive
alternatives--commercial banks, for example, are returning to this arena--and
this has constrained the opportunities for high-yield bond investors.
 
PERFORMANCE AND STRATEGY REVIEW
 
Your fund provided solid returns for the six-month period, with capital
appreciation augmenting income.
 
  We continued our even-keel approach to managing the fund, attempting to
balance the advantages of higher yields and appreciation opportunities against
additional risk. Toward this end, we maintained a strong focus on B-rated
issues. We like the pickup in yield these bonds provide without undue exposure
to interest rate and credit risk. As always, we draw heavily on our in-house
research expertise to help us assess each issue's risk and reward potential.
Allocations remain widely diversified among industry sectors to limit potential
problems from any single area. The only change of note during the six-month
period was a reduction in the strongly performing energy area, reflecting
profit-taking in these investments.
 
OUTLOOK
 
Six months ago we sounded a note of caution in looking over the high-yield
landscape. While we anticipated solid returns if the economy continued to grow,
we worried about the high valuations in our market--a concern shared by many
investors about stocks--and also about a possible rise in defaults in the wake
of the large number of new offerings. So far, the default rate has been
declining, and if the year-to-date trend continues, 1997 could have the lowest
such rate in three years. The high-yield market has hardly missed a beat,
principally because of the economy's amazing momentum. We said last winter we
would be happy to be surprised on the upside, and we are happy.
 
  We see nothing on the immediate horizon that might bring this bull market to
a halt. Unless the Fed makes a serious miscalculation, we would expect a
continuation of moderate inflation and a return to moderate growth--a good
environment for all debt securities. Closer to home, we believe the high-yield
market may be more resilient than in the past, when it was less diverse and
problems with one or two high-profile issuers could have a large impact. At the
same time, we know that today's narrow yield spreads among bonds of different
credit quality will eventually correct, and that defaults will rise when and if
the economy slows significantly. We would emphasize equally that our near-term
outlook is positive, and we would expect high-yield bonds to remain rewarding
over the long term.

GROWTH EQUITY FUND
 
Perhaps it was William Penn who coined the adage "April showers bring May
flowers", but no other five words could better describe the stock market
behavior this year. The new year brought it surprisingly strong earnings and an
early burst of enthusiasm, but by late March and the first part of April
investors found the climate dreary and depressing with no expectation that the
stock market would soon bottom and begin a recovery into record territory. At
the bottom few market pundits had words of encouragement. The bears were almost
gleeful, having warned that a downturn was justifiable, necessary, and long
overdue. Many bulls turned cautious, pulling in their horns and looking a bit
sheepish. Thus were the seeds of the market's dramatic advance sown.
 
  The second half of April and early May brought light and nourishment to the
stock market. The light was economic news that showed a non-inflationary
expansion and the nourishment was provided by the long list of better-than-
expected earnings reports. With the bond market firming and turning higher, the
Fed choosing to keep rates unchanged in May, and inflows of cash to mutual
funds continuing at a solid clip, there were no significant impairments to the
stock market's recovery. By the end of June the rally had carried the stock
market over 20% from its lows.
 
  The Growth Equity Fund advanced 15.94% in the first half of 1997 which
compares with the 15.40% return for the Lipper Growth Index, the 14.28% return
for the overall Lipper Growth Fund average and the S&P 500's return of 20.54%.
For the twelve month period ended June 30 the Growth Equity Fund earned a
return of 27.56%. This return is better than both the 25.54% return of the
Lipper Growth Index and the 23.96% earned by the average growth fund in the
broad Lipper universe, but trailed the S&P 500's gain of 34.72%.
 
  The Fund's first half improvement came primarily from strength in the
Healthcare (+31.9%), Financial (+20.5%) , and Capital Goods (+19.4%) sectors,
but only Healthcare actually outperformed the S&P 500 Stock Index. Relative
performance was negatively impacted by the underperformance of the Utility
(+17.9%), Consumer Staples (+16.3%), Basic Material (+16.7%), Technology
(+12.5%), Consumer Cyclicals (+5.5%), and Energy (+3.7%) sectors.
Transportation (+16.6%) was only nominally represented in the portfolio.
 
INDEPENDENCE CAPITAL MANAGEMENT, INC.
INVESTMENT ADVISER
VALUE EQUITY FUND
 
The fund's value approach is to provide superior investment returns with below-
average risk. We seek investments in businesses that generate high returns on
invested capital, run by managements who seek to maximize those returns and
create wealth for shareholders: through reinvestment in high-return business
opportunities, through astute acquisitions, and through share repurchase. Those
high returns must be sustainable, which is only achievable in companies with
very strong competitive advantages. A major goal of our in-depth primary
research is to assess these advantages and the industrial strengths upon which
they depend. Our long-term perspective is a tremendous advantage in identifying
these situations and in buying them opportunistically in a marketplace which is
often driven by transitory considerations. The right price is very important in
that we believe that it should encompass only a moderate degree of risk
relative to upside potential, in our best judgment.
 
  The US stock market keeps rising relentlessly, confounding the skeptics. As
measured by the total return of the S&P 500, the market has now advanced 104%
in the 30 months since year-end 1994, equaling its steepest ascent in history.
 
  What would have been considered miraculous only a few years ago, low
unemployment with low inflation; has become recurring economic reality. In May,
the jobless rate fell to 4.8%, the lowest in 24 years. Defying standard
economic theory, which says that light job markets lead to inflation, the
consumer price index subsided also, rising only 2.2% from a year earlier. When
one stands back from the usual gyrations in short-term economic data, there are
few signs of disruption to this favorable economic environment. If we were to
worry, it would be about tightening labor markets. Rising wage rates could
boost inflation somewhat, but we believe that a protracted problem with
inflation can be caused only by too-rapid growth of the money supply, which we
do not see at this time.
 
  The international economic environment is favorable as well. Inflation is low
virtually worldwide, and the disciplined approach of governments and central
banks to money supply and deficits suggests inflation will remain in check. The
changing dynamics of foreign pension plans are another interesting (and
bullish) investment ingredient. Many foreign countries have demographic
profiles similar to the US: rapid growth in the number of impending retirees,
but much slower growth in the labor force that must provide for them. In
contrast to the US, however, most foreign pension plans are unfunded. Instead
of having money already set aside and invested, these plans operate on a pay-
as-you-go basis. As foreign governments and corporations attempt to fund their
obligations, demand for equities could increase significantly. According to a
report by Goldman Sachs, $1.8 trillion of additional pension money is forecast
to be invested into worldwide equities by 2000.

MANAGEMENT DISCUSSION OF FUND PERFORMANCE
VALUE EQUITY FUND (CONT'D)
 
  Generally, the stock market keys off of economic news, but recently the
market is the news. According to some reports, if the Federal Reserve raises
rates, an important reason will be concern about excessive speculation in the
stock market rather than about ordinary economic trends. But what is actually
happening in the stock market? Let's take a look.
 
  Most observers of the financial markets draw distinctions among the Nasdaq
Composite index of over-the-counter stocks, the NYSE Composite, the Dow Jones
Industrials, the S&P 400 and 500, and various international market indices,
among others. If pressed to point to a single index that measures "the market"
best, most would probably select the S&P 500. Few know how heavily the S&P 500
is influenced by a small group of very large-capitalization stocks and,
therefore, how much the performance of the S&P 500 deviates from that of the
average large-cap portfolio, unless that portfolio contains disproportionate
positions in Microsoft, Intel, General Electric and a few others.
 
  The effect of these super-large stocks can be seen in comparing the S&P 500,
which is capitalization weighted and on which, therefore, large stocks have
much more influence than smaller stocks, with an unweighted index of those same
500 stocks (each stock having equal influence). According to The Leuthold
Group, the S&P 500 outperformed an equally weighted index of the same 500
stocks by 5.9 percentage points in 1995, by 3.3 percentage points in 1996 and
by 3.6 percentage points from the beginning of this year through June 18. That
disparity occurred because the large capitalization stocks outperformed the
other stocks in the index by a wide margin. We believe large stocks have
benefited from the torrent of money flowing into mutual funds. The easiest way
for the funds to put these cash inflows to work is by purchasing the largest,
most liquid stocks. Also, the unusual length of the bull market has made
"momentum" investing (what goes up will continue to go up) more popular,
further lifting this same group of very large-cap stocks to high multiples. No
wonder so few portfolio managers have been performing as well as "the market"
recently.
 
  Does the recent dominance of the largest stocks mean we should push our
portfolios into them, or that investors should just give up and buy the S&P 500
index? Our answer won't surprise you: no. Let's look at longer periods of time,
again using data from The Leuthold Group: During the 1960s, an equally weighted
version of the S&P 500 outperformed the capitalization weighted S&P 500 by 4.8
percentage points per year. In the 1970s, the equally weighted index
outperformed by 4.0 percentage points per year. In the 1980s, equally weighted
won again, by 1.4 percentage points per year. The equally weighted 500 stocks
continued to outperform from 1990 through 1994, beating the capitalization
weighted S&P 500 by 2.1 percentage points per year.
 
CONCLUSION
 
The most recent two-and-a-half years of outperformance by the very largest
components of the S&P 500 have been the exception, not the rule. In contrast to
momentum investors who subscribe to the premise that what goes up will continue
to go up, we believe that what goes up too much will eventually come back down.
Given the high valuations of many very large capitalization S&P 500 stocks at
this time, we think it's unlikely the capitalization weighted index will
continue to perform better than more balanced portfolios for much longer. It
follows, in our opinion, that now is an especially inopportune time to "index."
 
  We continue to invest in businesses that are worth inherently more, in our
judgement, than their asking prices. Looked at another way, we hope to preserve
our clients' capital in all market conditions, including market corrections,
because we have maintained our value-price discipline and because the
businesses in which we invest tend to generate excess cash, which becomes more
valuable in difficult markets.
 
  In general, we find the stock market to be fully valued at this time.
However, we are not market timers and do not have an opinion as to whether the
S&P 500 will be higher or lower a month from now than it is today. We buy
individual stocks, not the market. Using our above-average cash reserves, we
will be opportunistic in buying stocks we like whenever we can get them at
favorable prices.

FLEXIBLY MANAGED FUND
 
Financial markets and most subsectors were almost universally strong in the
first half of 1997. Equity markets completed their ninth and tenth consecutive
positive quarters. This hasn't happened in 40 years. Persistently low levels of
inflation and a strong (but not too strong), economy were the key positives.
The Federal Reserve modestly raised interest rates, but this only dampened
enthusiasm temporarily. Meanwhile, the potential vertigo inherent in today's
historically high equity valuations remains largely ignored.
 
  We were not well-positioned for the market's broad trends. First of all, by
design, we attempt to hold down our risk and currently are only about half
invested in common stocks. Our other investments provided solid gains, but not
when compared with equities. Second, we hold only minor positions in the large
growth companies that dominate the S&P 500. The frenzy that has driven up
prices for these securities may or may not be justified, but the resulting high
valuations seem inappropriate for a risk-averse fund. Third, we have large
exposure to electric utility and energy sector companies, groups that
significantly lagged. Fortunately, a series of individual security successes
provided respectable returns.
 
PORTFOLIO HIGHLIGHTS
 
The media group, a long-time portfolio focus, and particularly NEW YORK TIMES
and WASHINGTON POST, continued to generate outstanding gains in the first half.
We have been modestly trimming these holdings while maintaining industry
exposure with purchases of TIME WARNER convertible bonds. We swapped portions
of our HOMESTAKE MINING and NEWMONT MINING holdings for an expanded position in
SANTA FE PACIFIC GOLD. This company was then merged into Newmont, re-
establishing a larger but cheaper position in that stock. Unfortunately, the
substantial weakness in gold mining generally left us with an insignificant
loss rather than the gains we might normally have realized with such a
successful series of interrelated trades. We initiated a 1% holding in
WHEELABRATOR TECHNOLOGIES, now the object of a takeover. We continued to add to
our AMERADA HESS and UNION TEXAS PETROLEUM holdings. Finally, we saw through to
completion the merger/sale of PHH, one of our stellar long-term holdings. We
are now attempting to maximize the value of numerous PHH hedging transactions.
 
OUTLOOK
 
Stock market cycles, economic cycles, and credit cycles always seem similar,
but only when viewed through the rear window of history. We expect fairly
strong economic growth to continue and with inflation seemingly subdued, it
appears some time will elapse before the next move in Federal Reserve policy.
Nevertheless, when that action does come, we anticipate it will be another
incremental increase in interest rates. As for the stock market, we have not a
shadow of a doubt that it is overvalued and will decline, but we don't know
when or from what level.

PENN SERIES FUNDS, INC.
MANAGEMENT DISCUSSION OF FUND PERFORMANCE
INTERNATIONAL EQUITY FUND
 
Falling interest rates, strengthening balance sheets and a change in the
attitude of corporate management toward shareholders were some of the factors
that helped to spur strong returns in Europe and Latin America during the
second quarter. Asian markets continued their falling trend due to structural
issues like currency risk, interest rate pressure, falling levels of corporate
profitability, and weakening export demand from Europe and Japan. Overall, this
did not affect the fund's performance since we had already reduced most of our
exposure to the peripheral Asian markets.
 
EUROPE
 
The major continental European markets are close to being fully valued after a
double-digit run-up in equity prices year to date, e.g., France +23%, Germany
+29%, Switzerland +44%, the Netherlands +35% (in local currency terms). The
region's long string of double-digit returns over the last 18 months is reason
enough to become prudent (although their outperformance doesn't mean they won't
continue to rise!). Based on still falling bond and earnings yields, 8 out of
14 European markets still have the potential to produce returns in the low
teens over the next 12 months.
 
  Still, prevailing corporate sentiment indicates a lack of confidence in a
sustained economic recovery. At the time of the US dollar collapse in 1994-95
European corporations went on a capital investment spending spree. The
resulting imbalance between output and demand has left them cautious, and
inventories are at an unusually low level for this stage in the economic cycle.
So far, corporate Europe has taken the easy road to restructuring, of the sort
that can be achieved through plant closings and employee layoffs. It needs to
do more. The focus should now shift toward more efficient management of the
capital base, including share buybacks, and development of new products. Faced
with the challenges created by falling tariffs and deregulation around the
globe, European corporations can no longer afford to automatically reinvest
retained earnings as they compete with companies in emerging markets with cheap
source of inputs. Nor is domestic leadership a guarantee of survival--European
firms need to create strong global market share and globally recognized brands.
As a result, merger and acquisition activity in Europe, propelled by the need
to grow market share, will remain strong. Some of our current portfolio
holdings that are particularly well positioned to meet these global challenges
include retailer Carrefour and insurer Axa in France, carmaker BMW in Germany,
and publishing giant Elsevier in the Netherlands.
 
  Despite less compelling valuations in Europe than a year ago, we are still
finding enough good, attractively priced companies in which to invest and, for
now, are maintaining our current regional allocation of about 57%. We started
to raise cash in the second quarter by taking profits in France and Germany,
where we now have a combined 14% weighting.
 
  In the UK corporate profits are strong while stock market sentiment is weak,
a good combination for keeping close to a full market weight. The Labor Party's
election win after 18 years of Tory rule should not impact the UK's success in
attracting global capital due to its highly skilled labor force and well-
regulated business environment. The economy hasn't looked this rosy since the
1980's, as reflected by the strength of the sterling and the potential need to
curb the pace of economic growth through further interest rate hikes.
 
  As we've stated repeatedly, a country's economic environment is less
important in our market analysis than the level of market liquidity and the
existence of companies with solid fundamentals. This is reflected in our
overweight positions in three of the best-performing markets in Europe year to
date; Switzerland, the Netherlands and Sweden, where we have a combined
weighting of 20% vs. the MSCI EAFE at 14%.
 
JAPAN
 
The Japanese economy is showing growth of around 1% of 1997 after four years of
recession. Due to corporate restructuring, cost controls and sales growth, the
operating environment for large- and mid-size corporations in the manufacturing
sector is generating large amounts of cash flow. For most companies we own,
free cash flow is increasing at about 40% relative to the last peak prior to
the 1989 bubble. Valuation ratios in the Japanese market are still giving mixed
signals: PCF 10X, PB 2.2X and PE 42X (ex-financials and utilities). Earnings,
however, continue to be strong and over the next 12 months should grow by about
38% for the Topix Index. Our allocation to this market has increased to 27%, v.
22% at year end.
 
CURRENCIES
 
The US dollar remained extremely strong against the major European currencies
with the exception of the pound sterling, the fund benefitted from our unhedged
position in the latter. We maintained hedges on the German mark, French franc
and Swiss franc. Our hedge against the yen worked against us in view of the
yen's strong appreciation during the quarter.

SMALL CAPITALIZATION FUND
 
Although small-cap stocks as a class have now underperformed large-cap stocks
for three years, we continue to deliver positive returns, equaling or exceeding
our benchmark, the Russell 2000, in the 1997 second quarter and first half. We
achieved these results by being disciplined in our approach of buying
reasonably valued companies based on their business fundamentals. Our long-term
perspective is a tremendous advantage in identifying undervalued businesses and
buying them opportunistically in a marketplace which is driven by transitory
considerations. The right price is very important in that we believe it should
encompass only a moderate degree of risk relative to upside potential. Our
largest positions include Magellan Health Services, the largest provider of
managed-care behavioral health services; Wang Laboratories, a systems
integration and computer maintenance firm; St. Mary Land & Exploration, an
exploration and production company; E. W. Blanch Holdings, and insurance
broker; and A. Schulman, which produces plastics and resins.
 
  Magellan Health exemplifies the qualities we look for in an investment,
including high returns on invested capital, a leading competitive position to
help protect those returns, significant free cash flow which is being used to
create shareholder value and a management team oriented toward shareholder
interests--and, on top of that, a reasonable valuation. We began accumulating
Magellan in November 1995 at an average price in the high teens. More recently,
Magellan sold its brick-and-mortar hospitals business, realizing about $400
million of cash, which it is using to make acquisitions that complement its
managed care business. Magellan is now focused solely on providing managed-care
mental health programs for corporations and government agencies. It is the
leader in this field, which offers excellent prospects for revenue and earnings
growth. At a recent price of $30 a share, or about 15 times anticipated fiscal
1998 earnings, and with its strong cash flow and favorable growth
characteristics, we still consider the stock to be reasonably valued.

EMERGING GROWTH FUND
 
We are pleased to have the opportunity to report on our progress as manager of
the ICMI/Robertson Stephens Emerging Growth portfolio. Commencing the portfolio
on 5/1/97, our two-month performance was aided by a strong rally in small-cap
stocks that began in May. From May 1, 1997, through June 30, 1997, the
subaccount was up 22.60% versus an increase of 17.67% in the Russell 2000
Growth index.
 
  While our investment process is bottom up, driven by stock selection,
portfolio positions tended to be overweighted in several Russell sectors. The
portfolio was overweighted in Technology and Consumer Discretionary Services,
and underweighted in the Health Care sector as measured by Frank Russell.
 
  Also of note was the announcement that Robertson Stephens agreed to be
acquired by BankAmerica, subject to regulatory approvals. If approval is
achieved, we expect the transaction to close in the fourth quarter of 1997. We
are extremely excited about becoming part of the BankAmerica organization. They
will enable us to maintain the unique culture that has made us successful in
the last 18 years, while also affording us access to expanded capital and
resources that will enable us to grow our investment management franchise into
the next decade.
 
  In managing the portfolio, the management team is looking for emerging growth
companies that are growing revenues and earnings by a minimum of 20% annually.
These companies come from traditional growth sectors and industries, and also
come from newer "emerging" industries. These emerging industries develop
quickly around new technologies and market opportunities. We believe our
emerging growth research team provides us a competitive advantage in
identifying and understanding these industries and companies before may of our
competitors on Wall Street.
 
  One such emerging sector we have identified is Information Technology
Education. An opportunity has developed for companies to provide training and
education in a wide range of software programs. In the past many companies
would maintain an IT training capability in house. However, today many
companies now look to hire an information technology provider to train their
employees on an as needed basis. We own a number of companies that provide this
capability including Strayer Education and Education Management Corp.
 
  A resurgence in the Lodging industry has created an improved operating
environment for established and new players in the sector. We are attracted to
several companies in this sector, including Four Seasons Hotel Corporation.
Four Seasons operates hotels at the highest end of the luxury segment where
there is little competition and a finite supply of rooms. This gives Four
Seasons strong pricing power. Room rates in many of their properties have risen
throughout the year, helping to improve profitability.
 
  In conclusion, we are pleased to manage a portfolio in the exciting area of
emerging growth companies. We look forward to our continued dialogue with Penn
Mutual and your clients.

PENN SERIES FUNDS, INC.
NOTES TO FINANCIAL STATEMENTS - JUNE 30, 1997 (UNAUDITED)
- --------------------------------------------------------------------------------
1 - SIGNIFICANT ACCOUNTING POLICIES
 
  Penn Series Funds, Inc. (Penn Series) was incorporated in Maryland on April
22, 1982. Penn Series is registered under the Investment Company Act of 1940,
as amended, as an open-end, diversified management investment company.
 
  Penn Series is presently offering shares in its Money Market, Quality Bond,
High Yield Bond, Growth Equity, Value Equity, Flexibly Managed, International
Equity, Small Capitalization and Emerging Growth Funds (the Funds). It is
authorized under its Articles of Incorporation to issue a separate class of
shares in one additional fund. The Fund would have its own investment objective
and policy.
 
  The following is a summary of significant accounting policies followed by
Penn Series in the preparation of its 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 amounts of assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from these estimates.
 
  INVESTMENT VALUATION:
  MONEY MARKET FUND - Investments in securities are valued under the amortized
cost method, which approximates current market value. Under this method,
securities are valued at cost on the date of purchase and thereafter a
proportionate amortization of any discount or premium until maturity is
assumed. Penn Series has agreed to maintain a dollar weighted average portfolio
maturity appropriate to the objective of maintaining a stable net asset value
per share. The Penn Series Board of Directors (The Board) has established
procedures reasonably designed to stabilize the net asset value per share for
purposes of sales and redemptions at $1.00. The Board performs regular review
and monitoring of the valuation in an attempt to avoid dilution or unfair
results to shareholders.
 
  QUALITY BOND, HIGH YIELD BOND, GROWTH EQUITY, VALUE EQUITY, FLEXIBLY MANAGED,
INTERNATIONAL EQUITY, SMALL CAPITALIZATION AND EMERGING GROWTH FUNDS -
 Portfolio securities listed on a national securities exchange are valued at
the last sale price on the securities exchange or securities market on which
such securities primarily are traded or, if there has been no sale on that day,
at the mean between the current closing bid and asked prices. All other
securities for which over-the-counter market quotations are readily available
will be valued on the basis of the mean between the last current bid and asked
prices. When market quotations are not readily available, or when restricted or
other assets are being valued, the securities or assets will be valued at fair
value as determined by The Board.
 
  The high yield securities in which the High Yield Bond Fund may invest are
predominantly speculative as to the issuer's continuing ability to meet
principal and interest payments. The value of the lower quality securities in
which the High Yield Bond Fund may invest will be affected by the credit
worthiness of individual issuers, general economic and specific industry
conditions, and will fluctuate inversely with changes in interest rates. In
addition, the secondary trading market for lower quality bonds may be less
active and less liquid than the trading market for higher quality bonds.
 
  FOREIGN CURRENCY TRANSLATION - The books and records of the Funds are
maintained in U.S. dollars. Foreign currency amounts are translated into U.S.
dollars on the following basis: market value of investment securities, assets
and liabilities at the current rate of exchange; and purchase and sales of
investment securities, income and expenses at the relevant rates of exchange
prevailing on the respective dates of such transactions.
 
  The Funds do not isolate that portion of realized and unrealized gains and
losses on investments in equity securities which are due to changes in the
foreign exchange rate from that which is due to changes in market prices of
equity securities.
 
  Foreign security and currency transactions may involve certain considerations
and risks not typically associated with those of U.S. dollar denominated
transactions as a result of, among other factors, the level of governmental
supervision and regulation of foreign securities markets and the possibility of
political or economic instability.
 
  SECURITY TRANSACTIONS AND INVESTMENT INCOME: Security transactions are
accounted for on the trade date. Dividend income is recorded on the ex-dividend
date and interest income is accrued as earned. The cost of investment
securities sold is determined by using the specific identification method for
both financial reporting and income tax purposes.
 
  DIVIDENDS TO SHAREHOLDERS: Dividends of investment income and realized
capital gains of the Quality Bond, High Yield Bond, Growth Equity, Value
Equity, Flexibly Managed, International Equity Small Capitalization and
Emerging Growth Funds will be declared and paid annually. Dividends of net
investment income of the Money Market Fund are declared daily and paid monthly.
Income distributions and capital gain distributions are determined in
accordance with income tax regulations which may differ from generally accepted
accounting principles. These differences are primarily due to differing
treatments for mortgage-backed securities, market discount and foreign currency
transactions.
 
  FEDERAL INCOME TAXES: It is the policy of each of the Funds to comply with
the requirements of the Internal Revenue Code applicable to regulated
investment companies and to distribute all of its taxable income, including
realized gains, to its shareholders. Therefore, no provision is made for
federal income or excise taxes.

NOTES TO FINANCIAL STATEMENTS - JUNE 30, 1997 (UNAUDITED)

2 - DERIVATIVE FINANCIAL INSTRUMENTS
 
OFF-BALANCE SHEET RISK
 
  The Funds may trade financial instruments with off-balance sheet risk in the
normal course of investing activities and to assist in managing exposure to
market risks such as interest rates and foreign currency exchange rates. These
financial instruments include written options, forward foreign currency
exchange contracts and futures contracts.
 
  The notional or contractual amounts of these instruments represent the
investment the Funds have in particular classes of financial instruments and do
not necessarily represent the amounts potentially subject to risk. The
measurement of the risks associated with these instruments is meaningful only
when all related and offsetting transactions are considered.
 
DERIVATIVE FINANCIAL INSTRUMENTS HELD OR ISSUED FOR PURPOSES OTHER THAN TRADING
 
  FUTURES CONTRACTS - Each of the Funds, other than Money Market, may enter
into financial futures contracts for the delayed delivery of securities,
currency or contracts based on financial indices on a future date. A Fund is
required to deposit either in cash or securities an amount equal to a certain
percentage of the contract amount. Subsequent payments are made or received by
a Fund each day, dependent on daily fluctuations in the value of the underlying
security, and are recorded for financial statement purposes as unrealized gains
or losses by a Fund. A Fund's investment in financial futures contracts is
designed only to hedge against anticipated future changes in interest or
exchange rates. Should interest or exchange rates move unexpectedly, a Fund may
not achieve the anticipated benefits of the financial futures contracts and may
realize a loss. There were no open futures contracts at June 30, 1997.
 
  WRITTEN OPTIONS - Each of the Funds, other than Money Market, may write
covered calls. Additionally, each of the Funds may buy put or call options for
which premiums are paid whether or not the option is exercised. Premiums
received from writing options which expire are treated as realized gains.
Premiums received from writing options which are exercised or are closed are
offset against the proceeds or amount paid on the transaction to determine the
realized gain or loss. If a put option is exercised, the premium increases the
cost basis of the securities purchased by a Fund. As writer of an option, the
Fund may have no control over whether the underlying securities may be sold
(call) and, as a result, bears the market risk of an unfavorable change in the
price of the securities underlying the written option. The Flexibly Managed
Fund has entered into put options during the period ended June 30, 1997.
Purchased put options open and outstanding at June 30, 1997 are disclosed in
the schedule of investments.
 
  FORWARD FOREIGN CURRENCY CONTRACTS - The Funds may enter into forward foreign
currency exchange contracts as a way of managing foreign exchange rate risk. A
Fund may enter into these contracts to fix the U.S. dollar value of a security
that it has agreed to buy or sell for the period between the date the trade was
entered into and the date the security is delivered and paid for. A Fund may
also use these contracts to hedge the U.S. dollar value of securities it
already owns denominated in foreign currencies.
 
  Forward foreign currency contracts are valued at the forward rate, and are
marked-to-market daily. The change in market value is recorded by the Fund as
an unrealized gain or loss. When the contract is closed, the Fund records a
realized gain or loss equal to the difference between the value of the contract
at the time it was opened and the value at the time it was closed.
 
  The use of forward foreign currency contracts does not eliminate fluctuations
in the underlying prices of the Fund's portfolio securities, but it does
establish a rate of exchange that can be achieved in the future. Although
forward foreign currency contracts limit the risk of loss due to a decline in
the value of the hedged currency, they also limit any potential gain that might
result should the value of the currency increase. In addition, the Funds could
be exposed to risks if the counterparties to the contracts are unable to meet
the terms of their contracts. The Flexibly Managed and International Equity
funds have entered into forward foreign currency contracts for the period ended
June 30, 1997.
 
  At June 30, 1997 there were no open contracts in the Flexibly Managed Fund.
Open forward foreign currency contracts held by the International Equity Fund
at June 30, 1997 were as follows:

TO OUR VARIABLE LIFE INSURANCE CONTRACTHOLDERS:
 
  I am delighted to present the Semi-Annual Reports of Penn Series Funds, Inc.,
Neuberger & Berman Advisers Management Trust, American Century Variable
Portfolios, Inc., Fidelity Investments Variable Insurance Products Fund and
Variable Insurance Products Fund II, and Morgan Stanley Universal Funds, Inc.
for the six month period ending June 30, 1997.
 
  The first 6 months of 1997 were not too much different from what we've been
seeing in the equity markets for the previous 2 years--lots of volatility, but
with a dramatic move upward.
 
  As of June 30, the market as measured by the S&P 500 was up 20.59%, and the
Russell 2000, a measure of small cap stock performance was up 9.31%.
 
  But this bull market trend was interrupted by a near 10% correction amid
fears of continued increases in interest rates by the Federal Reserve to cool
an economy that seemed overheated. However, as the second quarter progressed,
economic reports signaled a slow down from the first quarter's rapid pace, and
inflation remained in check. Corporate earnings were up over 10% and the market
took off once again, rising more than 20% in May and June.
 
  So at this point the "pillars" of the stock market are very solid--benign
inflation and interest and strong corporate earnings. The $64,000 question of
course is, "With the Dow above 8000 and price-earnings ratios above 20, is the
market valuing all of this good news too highly?"
 
  As we've discussed before, if you are a long term investor, try not to be too
influenced with the short term twists and turns of the stock market. Rather,
working with your financial planner, apply solid risk reduction techniques such
as diversification and regular rebalancing of your portfolio to meet your long
term needs.
 
  Penn Mutual's variable products now offer more diversification possibilities
than ever before with 4 new additions to our family of funds:
 
    ICMI/Robertson Stephens Emerging Growth Fund
    Morgan Stanley Emerging Markets Equity (Int'l) Portfolio
    Neuberger & Berman AMT Partners Portfolio
    Fidelity Investments VIP II Index 500 Portfolio
 
  Your CORNERSTONE VUL II & VARIABLE ESTATEMAX policies are designed to help
you maintain a steady, long-term approach to investing. It brings the
experience and expertise of various investment advisers to help you build a
financial plan that best suits your individual needs. And we encourage you to
work with your financial planner to take full advantage your policy's features
and investment choices.

accounts offered under CORNERSTONE VUL II & VARIABLE ESTATEMAX for the year

MANAGEMENT DISCUSSION OF FUND PERFORMANCE
 
QUALITY BOND FUND
 
Interest rates reversed course in the second quarter, falling 35-40 basis
points and retracting much of the upward surge in rates experienced in the
first three months of 1997. A sharp deceleration in economic growth led by a
drop-off in consumer spending, coupled with surprisingly low inflation data has
reduced anxieties about further Federal Reserve rate hikes and led to bond
market improvement.
 
  The estimates for second quarter growth range from 1-2%, a dramatic decline
from the 5.8% growth in the first quarter. Consumer spending has inexplicably
changed course, dropping off just as most market observers had assumed
continued growth. Conventional wisdom has it that consumer spending will
rebound due to 1) strong labor market with low unemployment, 2) high consumer
confidence 3) firm income levels and finally 4) rising wealth levels arising
from a soaring stock market. A firm rebound in domestic consumption will in all
likelihood lead to an initial sell-off in the bond market as most market
participants will look for renewed inflationary pressures and further monetary
tightening.
 
The greatest surprise for this economic cycle has been the absence of inflation
pressures. In fact, the producer price index posted its fifth straight monthly
decline in May, a feat not seen since 1952. It is this development that has
stayed the hand of the Federal Reserve this cycle and allowed this economic
cycle (which began in March, 1991), to persist well beyond the post war average
of 4.5 years.
 
  This low level of inflation also creates an environment where bond yields are
very attractive whenever they reach or approach 7%. With inflation at 2-3%,
real yields of 4-5% are extremely high by historical standards. Indeed, bond
returns have been historically very good when bonds are purchased with 5% real
yields. The second quarter offered another opportunity to purchase bonds with
high real yields which we took advantage of.
 
  Another key consideration in addressing the outlook for the domestic bond
market is the forecasts for economic growth overseas. In this economic cycle
the foreign economies, notably Japan, have been severely hampered by structural
problems. In Japan, the problems are rooted in a difficult banking environment,
itself a hangover from the excesses of the 1980's. Monetary policy in Japan,
the number two economy in the world, has been dramatically accommodative. Short
term rates have been driven down to 0.5%. In Europe, the effort to create a
unified currency has led to severely restrictive fiscal policies, slowing their
economies and resulting in highly stimulative monetary policies as well.
 
  This weakness in the major foreign economies has reduced inflationary
pressures and created liquidity that in many cases has been invested here in
the US. A reversal in these highly accommodative monetary policies should have
significant implications to our fixed income markets. We do not see changes
occurring in the near future.
 
  Currently, our position is long relative to our benchmark. We extended the
portfolio as rates moved above 7% in the long bond. In addition, we moved more
aggressively into corporate bonds as spreads widened in March and April.
 
  Performance for the quarter was fair as the net result of +3.64% for the
Quality Bond Fund exceeded the Salomon Brothers Broad Investment Grade Index of
3.60%. Note that beginning in the second quarter our benchmark measurement
index changed to the Salomon Index vs the Lipper Bond averages. Year to date
figures are misleading due to differences in duration requirements between the
Salomon Index and the Lipper averages.

MANAGEMENT DISCUSSION OF FUND PERFORMANCE
 
HIGH YIELD BOND FUND
 
The stars were aligned for the high-yield bond market during the past six
months. Virtually all the principal influences on this market were positive if
not exuberant, especially the U.S. economy and the market's own fundamentals.
The rise in interest rates that dampened returns on high-quality bonds in the
first quarter was not a problem for the credit-sensitive, high-yield market. As
a result, high-yield bonds significantly outperformed high-quality bonds for
the six months ended June 30.
 
MARKET ENVIRONMENT
 
Many of the same factors that drove stocks higher fueled the rise in high-yield
(junk) bond prices. Topping this list were the continued and largely unexpected
strength in corporate earnings and the economy's 5.8% annualized growth rate in
the first quarter--roughly double the trend rate since the current upturn began
in 1991. In an attempt to cool this pace and preempt a rise in inflation, the
Federal Reserve raised the federal funds rate (from 5 1/4% to 5 1/2%) for the
first time since 1995, and interest rates rose across the yield curve. However,
stocks and high-yield bonds, which typically are driven by economic growth and
corporate earnings expectations, recovered quickly and forged ahead.
 
  High-yield bonds also benefited from extremely strong demand relative to the
supply of issues. Cash flow into retail high-yield mutual funds was heavy; the
number of institutional investors allocating assets to this market sector
continued to rise; and structured securities called collateralized bond
obligations (CBOs) absorbed billions of dollars worth of high-yield bonds. On
the supply side, new issues appeared at a steady clip, particularly from
smaller companies. Nevertheless, many potential high-yield bond issuers have
elected to refinance existing bonds through a growing number of attractive
alternatives--commercial banks, for example, are returning to this arena--and
this has constrained the opportunities for high-yield bond investors.
 
PERFORMANCE AND STRATEGY REVIEW
 
Your fund provided solid returns for the six-month period, with capital
appreciation augmenting income.
 
  We continued our even-keel approach to managing the fund, attempting to
balance the advantages of higher yields and appreciation opportunities against
additional risk. Toward this end, we maintained a strong focus on B-rated
issues. We like the pickup in yield these bonds provide without undue exposure
to interest rate and credit risk. As always, we draw heavily on our in-house
research expertise to help us assess each issue's risk and reward potential.
Allocations remain widely diversified among industry sectors to limit potential
problems from any single area. The only change of note during the six-month
period was a reduction in the strongly performing energy area, reflecting
profit-taking in these investments.
 
OUTLOOK
 
Six months ago we sounded a note of caution in looking over the high-yield
landscape. While we anticipated solid returns if the economy continued to grow,
we worried about the high valuations in our market--a concern shared by many
investors about stocks--and also about a possible rise in defaults in the wake
of the large number of new offerings. So far, the default rate has been
declining, and if the year-to-date trend continues, 1997 could have the lowest
such rate in three years. The high-yield market has hardly missed a beat,
principally because of the economy's amazing momentum. We said last winter we
would be happy to be surprised on the upside, and we are happy.
 
  We see nothing on the immediate horizon that might bring this bull market to
a halt. Unless the Fed makes a serious miscalculation, we would expect a
continuation of moderate inflation and a return to moderate growth--a good
environment for all debt securities. Closer to home, we believe the high-yield
market may be more resilient than in the past, when it was less diverse and
problems with one or two high-profile issuers could have a large impact. At the
same time, we know that today's narrow yield spreads among bonds of different
credit quality will eventually correct, and that defaults will rise when and if
the economy slows significantly. We would emphasize equally that our near-term
outlook is positive, and we would expect high-yield bonds to remain rewarding
over the long term.

GROWTH EQUITY FUND
 
Perhaps it was William Penn who coined the adage "April showers bring May
flowers", but no other five words could better describe the stock market
behavior this year. The new year brought it surprisingly strong earnings and an
early burst of enthusiasm, but by late March and the first part of April
investors found the climate dreary and depressing with no expectation that the
stock market would soon bottom and begin a recovery into record territory. At
the bottom few market pundits had words of encouragement. The bears were almost
gleeful, having warned that a downturn was justifiable, necessary, and long
overdue. Many bulls turned cautious, pulling in their horns and looking a bit
sheepish. Thus were the seeds of the market's dramatic advance sown.
 
  The second half of April and early May brought light and nourishment to the
stock market. The light was economic news that showed a non-inflationary
expansion and the nourishment was provided by the long list of better-than-
expected earnings reports. With the bond market firming and turning higher, the
Fed choosing to keep rates unchanged in May, and inflows of cash to mutual
funds continuing at a solid clip, there were no significant impairments to the
stock market's recovery. By the end of June the rally had carried the stock
market over 20% from its lows.
 
  The Growth Equity Fund advanced 15.94% in the first half of 1997 which
compares with the 15.40% return for the Lipper Growth Index, the 14.28% return
for the overall Lipper Growth Fund average and the S&P 500's return of 20.54%.
For the twelve month period ended June 30 the Growth Equity Fund earned a
return of 27.56%. This return is better than both the 25.54% return of the
Lipper Growth Index and the 23.96% earned by the average growth fund in the
broad Lipper universe, but trailed the S&P 500's gain of 34.72%.
 
  The Fund's first half improvement came primarily from strength in the
Healthcare (+31.9%), Financial (+20.5%) , and Capital Goods (+19.4%) sectors,
but only Healthcare actually outperformed the S&P 500 Stock Index. Relative
performance was negatively impacted by the underperformance of the Utility
(+17.9%), Consumer Staples (+16.3%), Basic Material (+16.7%), Technology
(+12.5%), Consumer Cyclicals (+5.5%), and Energy (+3.7%) sectors.
Transportation (+16.6%) was only nominally represented in the portfolio.

INVESTMENT ADVISER
VALUE EQUITY FUND
 
The fund's value approach is to provide superior investment returns with below-
average risk. We seek investments in businesses that generate high returns on
invested capital, run by managements who seek to maximize those returns and
create wealth for shareholders: through reinvestment in high-return business
opportunities, through astute acquisitions, and through share repurchase. Those
high returns must be sustainable, which is only achievable in companies with
very strong competitive advantages. A major goal of our in-depth primary
research is to assess these advantages and the industrial strengths upon which
they depend. Our long-term perspective is a tremendous advantage in identifying
these situations and in buying them opportunistically in a marketplace which is
often driven by transitory considerations. The right price is very important in
that we believe that it should encompass only a moderate degree of risk
relative to upside potential, in our best judgment.
 
  The US stock market keeps rising relentlessly, confounding the skeptics. As
measured by the total return of the S&P 500, the market has now advanced 104%
in the 30 months since year-end 1994, equaling its steepest ascent in history.
 
  What would have been considered miraculous only a few years ago, low
unemployment with low inflation; has become recurring economic reality. In May,
the jobless rate fell to 4.8%, the lowest in 24 years. Defying standard
economic theory, which says that light job markets lead to inflation, the
consumer price index subsided also, rising only 2.2% from a year earlier. When
one stands back from the usual gyrations in short-term economic data, there are
few signs of disruption to this favorable economic environment. If we were to
worry, it would be about tightening labor markets. Rising wage rates could
boost inflation somewhat, but we believe that a protracted problem with
inflation can be caused only by too-rapid growth of the money supply, which we
do not see at this time.
 
  The international economic environment is favorable as well. Inflation is low
virtually worldwide, and the disciplined approach of governments and central
banks to money supply and deficits suggests inflation will remain in check. The
changing dynamics of foreign pension plans are another interesting (and
bullish) investment ingredient. Many foreign countries have demographic
profiles similar to the US: rapid growth in the number of impending retirees,
but much slower growth in the labor force that must provide for them. In
contrast to the US, however, most foreign pension plans are unfunded. Instead
of having money already set aside and invested, these plans operate on a pay-
as-you-go basis. As foreign governments and corporations attempt to fund their
obligations, demand for equities could increase significantly. According to a
report by Goldman Sachs, $1.8 trillion of additional pension money is forecast
to be invested into worldwide equities by 2000.

MANAGEMENT DISCUSSION OF FUND PERFORMANCE
VALUE EQUITY FUND (CONT'D)
 
  Generally, the stock market keys off of economic news, but recently the
market is the news. According to some reports, if the Federal Reserve raises
rates, an important reason will be concern about excessive speculation in the
stock market rather than about ordinary economic trends. But what is actually
happening in the stock market? Let's take a look.
 
  Most observers of the financial markets draw distinctions among the Nasdaq
Composite index of over-the-counter stocks, the NYSE Composite, the Dow Jones
Industrials, the S&P 400 and 500, and various international market indices,
among others. If pressed to point to a single index that measures "the market"
best, most would probably select the S&P 500. Few know how heavily the S&P 500
is influenced by a small group of very large-capitalization stocks and,
therefore, how much the performance of the S&P 500 deviates from that of the
average large-cap portfolio, unless that portfolio contains disproportionate
positions in Microsoft, Intel, General Electric and a few others.
 
  The effect of these super-large stocks can be seen in comparing the S&P 500,
which is capitalization weighted and on which, therefore, large stocks have
much more influence than smaller stocks, with an unweighted index of those same
500 stocks (each stock having equal influence). According to The Leuthold
Group, the S&P 500 outperformed an equally weighted index of the same 500
stocks by 5.9 percentage points in 1995, by 3.3 percentage points in 1996 and
by 3.6 percentage points from the beginning of this year through June 18. That
disparity occurred because the large capitalization stocks outperformed the
other stocks in the index by a wide margin. We believe large stocks have
benefited from the torrent of money flowing into mutual funds. The easiest way
for the funds to put these cash inflows to work is by purchasing the largest,
most liquid stocks. Also, the unusual length of the bull market has made
"momentum" investing (what goes up will continue to go up) more popular,
further lifting this same group of very large-cap stocks to high multiples. No
wonder so few portfolio managers have been performing as well as "the market"
recently.
 
  Does the recent dominance of the largest stocks mean we should push our
portfolios into them, or that investors should just give up and buy the S&P 500
index? Our answer won't surprise you: no. Let's look at longer periods of time,
again using data from The Leuthold Group: During the 1960s, an equally weighted
version of the S&P 500 outperformed the capitalization weighted S&P 500 by 4.8
percentage points per year. In the 1970s, the equally weighted index
outperformed by 4.0 percentage points per year. In the 1980s, equally weighted
won again, by 1.4 percentage points per year. The equally weighted 500 stocks
continued to outperform from 1990 through 1994, beating the capitalization
weighted S&P 500 by 2.1 percentage points per year.
 
CONCLUSION
 
The most recent two-and-a-half years of outperformance by the very largest
components of the S&P 500 have been the exception, not the rule. In contrast to
momentum investors who subscribe to the premise that what goes up will continue
to go up, we believe that what goes up too much will eventually come back down.
Given the high valuations of many very large capitalization S&P 500 stocks at
this time, we think it's unlikely the capitalization weighted index will
continue to perform better than more balanced portfolios for much longer. It
follows, in our opinion, that now is an especially inopportune time to "index."
 
  We continue to invest in businesses that are worth inherently more, in our
judgement, than their asking prices. Looked at another way, we hope to preserve
our clients' capital in all market conditions, including market corrections,
because we have maintained our value-price discipline and because the
businesses in which we invest tend to generate excess cash, which becomes more
valuable in difficult markets.
 
  In general, we find the stock market to be fully valued at this time.
However, we are not market timers and do not have an opinion as to whether the
S&P 500 will be higher or lower a month from now than it is today. We buy
individual stocks, not the market. Using our above-average cash reserves, we
will be opportunistic in buying stocks we like whenever we can get them at
favorable prices.

FLEXIBLY MANAGED FUND
 
Financial markets and most subsectors were almost universally strong in the
first half of 1997. Equity markets completed their ninth and tenth consecutive
positive quarters. This hasn't happened in 40 years. Persistently low levels of
inflation and a strong (but not too strong), economy were the key positives.
The Federal Reserve modestly raised interest rates, but this only dampened
enthusiasm temporarily. Meanwhile, the potential vertigo inherent in today's
historically high equity valuations remains largely ignored.
 
  We were not well-positioned for the market's broad trends. First of all, by
design, we attempt to hold down our risk and currently are only about half
invested in common stocks. Our other investments provided solid gains, but not
when compared with equities. Second, we hold only minor positions in the large
growth companies that dominate the S&P 500. The frenzy that has driven up
prices for these securities may or may not be justified, but the resulting high
valuations seem inappropriate for a risk-averse fund. Third, we have large
exposure to electric utility and energy sector companies, groups that
significantly lagged. Fortunately, a series of individual security successes
provided respectable returns.
 
PORTFOLIO HIGHLIGHTS
 
The media group, a long-time portfolio focus, and particularly NEW YORK TIMES
and WASHINGTON POST, continued to generate outstanding gains in the first half.
We have been modestly trimming these holdings while maintaining industry
exposure with purchases of TIME WARNER convertible bonds. We swapped portions
of our HOMESTAKE MINING and NEWMONT MINING holdings for an expanded position in
SANTA FE PACIFIC GOLD. This company was then merged into Newmont, re-
establishing a larger but cheaper position in that stock. Unfortunately, the
substantial weakness in gold mining generally left us with an insignificant
loss rather than the gains we might normally have realized with such a
successful series of interrelated trades. We initiated a 1% holding in
WHEELABRATOR TECHNOLOGIES, now the object of a takeover. We continued to add to
our AMERADA HESS and UNION TEXAS PETROLEUM holdings. Finally, we saw through to
completion the merger/sale of PHH, one of our stellar long-term holdings. We
are now attempting to maximize the value of numerous PHH hedging transactions.
 
OUTLOOK
 
Stock market cycles, economic cycles, and credit cycles always seem similar,
but only when viewed through the rear window of history. We expect fairly
strong economic growth to continue and with inflation seemingly subdued, it
appears some time will elapse before the next move in Federal Reserve policy.
Nevertheless, when that action does come, we anticipate it will be another
incremental increase in interest rates. As for the stock market, we have not a
shadow of a doubt that it is overvalued and will decline, but we don't know
when or from what level.

MANAGEMENT DISCUSSION OF FUND PERFORMANCE
INTERNATIONAL EQUITY FUND
 
Falling interest rates, strengthening balance sheets and a change in the
attitude of corporate management toward shareholders were some of the factors
that helped to spur strong returns in Europe and Latin America during the
second quarter. Asian markets continued their falling trend due to structural
issues like currency risk, interest rate pressure, falling levels of corporate
profitability, and weakening export demand from Europe and Japan. Overall, this
did not affect the fund's performance since we had already reduced most of our
exposure to the peripheral Asian markets.
 
EUROPE
 
The major continental European markets are close to being fully valued after a
double-digit run-up in equity prices year to date, e.g., France +23%, Germany
+29%, Switzerland +44%, the Netherlands +35% (in local currency terms). The
region's long string of double-digit returns over the last 18 months is reason
enough to become prudent (although their outperformance doesn't mean they won't
continue to rise!). Based on still falling bond and earnings yields, 8 out of
14 European markets still have the potential to produce returns in the low
teens over the next 12 months.
 
  Still, prevailing corporate sentiment indicates a lack of confidence in a
sustained economic recovery. At the time of the US dollar collapse in 1994-95
European corporations went on a capital investment spending spree. The
resulting imbalance between output and demand has left them cautious, and
inventories are at an unusually low level for this stage in the economic cycle.
So far, corporate Europe has taken the easy road to restructuring, of the sort
that can be achieved through plant closings and employee layoffs. It needs to
do more. The focus should now shift toward more efficient management of the
capital base, including share buybacks, and development of new products. Faced
with the challenges created by falling tariffs and deregulation around the
globe, European corporations can no longer afford to automatically reinvest
retained earnings as they compete with companies in emerging markets with cheap
source of inputs. Nor is domestic leadership a guarantee of survival--European
firms need to create strong global market share and globally recognized brands.
As a result, merger and acquisition activity in Europe, propelled by the need
to grow market share, will remain strong. Some of our current portfolio
holdings that are particularly well positioned to meet these global challenges
include retailer Carrefour and insurer Axa in France, carmaker BMW in Germany,
and publishing giant Elsevier in the Netherlands.
 
  Despite less compelling valuations in Europe than a year ago, we are still
finding enough good, attractively priced companies in which to invest and, for
now, are maintaining our current regional allocation of about 57%. We started
to raise cash in the second quarter by taking profits in France and Germany,
where we now have a combined 14% weighting.
 
  In the UK corporate profits are strong while stock market sentiment is weak,
a good combination for keeping close to a full market weight. The Labor Party's
election win after 18 years of Tory rule should not impact the UK's success in
attracting global capital due to its highly skilled labor force and well-
regulated business environment. The economy hasn't looked this rosy since the
1980's, as reflected by the strength of the sterling and the potential need to
curb the pace of economic growth through further interest rate hikes.
 
  As we've stated repeatedly, a country's economic environment is less
important in our market analysis than the level of market liquidity and the
existence of companies with solid fundamentals. This is reflected in our
overweight positions in three of the best-performing markets in Europe year to
date; Switzerland, the Netherlands and Sweden, where we have a combined
weighting of 20% vs. the MSCI EAFE at 14%.
 
JAPAN
 
The Japanese economy is showing growth of around 1% of 1997 after four years of
recession. Due to corporate restructuring, cost controls and sales growth, the
operating environment for large- and mid-size corporations in the manufacturing
sector is generating large amounts of cash flow. For most companies we own,
free cash flow is increasing at about 40% relative to the last peak prior to
the 1989 bubble. Valuation ratios in the Japanese market are still giving mixed
signals: PCF 10X, PB 2.2X and PE 42X (ex-financials and utilities). Earnings,
however, continue to be strong and over the next 12 months should grow by about
38% for the Topix Index. Our allocation to this market has increased to 27%, v.
22% at year end.
 
CURRENCIES
 
The US dollar remained extremely strong against the major European currencies
with the exception of the pound sterling, the fund benefitted from our unhedged
position in the latter. We maintained hedges on the German mark, French franc
and Swiss franc. Our hedge against the yen worked against us in view of the
yen's strong appreciation during the quarter.

SMALL CAPITALIZATION FUND
 
Although small-cap stocks as a class have now underperformed large-cap stocks
for three years, we continue to deliver positive returns, equaling or exceeding
our benchmark, the Russell 2000, in the 1997 second quarter and first half. We
achieved these results by being disciplined in our approach of buying
reasonably valued companies based on their business fundamentals. Our long-term
perspective is a tremendous advantage in identifying undervalued businesses and
buying them opportunistically in a marketplace which is driven by transitory
considerations. The right price is very important in that we believe it should
encompass only a moderate degree of risk relative to upside potential. Our
largest positions include Magellan Health Services, the largest provider of
managed-care behavioral health services; Wang Laboratories, a systems
integration and computer maintenance firm; St. Mary Land & Exploration, an
exploration and production company; E. W. Blanch Holdings, and insurance
broker; and A. Schulman, which produces plastics and resins.
 
  Magellan Health exemplifies the qualities we look for in an investment,
including high returns on invested capital, a leading competitive position to
help protect those returns, significant free cash flow which is being used to
create shareholder value and a management team oriented toward shareholder
interests--and, on top of that, a reasonable valuation. We began accumulating
Magellan in November 1995 at an average price in the high teens. More recently,
Magellan sold its brick-and-mortar hospitals business, realizing about $400
million of cash, which it is using to make acquisitions that complement its
managed care business. Magellan is now focused solely on providing managed-care
mental health programs for corporations and government agencies. It is the
leader in this field, which offers excellent prospects for revenue and earnings
growth. At a recent price of $30 a share, or about 15 times anticipated fiscal
1998 earnings, and with its strong cash flow and favorable growth
characteristics, we still consider the stock to be reasonably valued.

EMERGING GROWTH FUND
 
We are pleased to have the opportunity to report on our progress as manager of
the ICMI/Robertson Stephens Emerging Growth portfolio. Commencing the portfolio
on 5/1/97, our two-month performance was aided by a strong rally in small-cap
stocks that began in May. From May 1, 1997, through June 30, 1997, the
subaccount was up 22.60% versus an increase of 17.67% in the Russell 2000
Growth index.
 
  While our investment process is bottom up, driven by stock selection,
portfolio positions tended to be overweighted in several Russell sectors. The
portfolio was overweighted in Technology and Consumer Discretionary Services,
and underweighted in the Health Care sector as measured by Frank Russell.
 
  Also of note was the announcement that Robertson Stephens agreed to be
acquired by BankAmerica, subject to regulatory approvals. If approval is
achieved, we expect the transaction to close in the fourth quarter of 1997. We
are extremely excited about becoming part of the BankAmerica organization. They
will enable us to maintain the unique culture that has made us successful in
the last 18 years, while also affording us access to expanded capital and
resources that will enable us to grow our investment management franchise into
the next decade.
 
  In managing the portfolio, the management team is looking for emerging growth
companies that are growing revenues and earnings by a minimum of 20% annually.
These companies come from traditional growth sectors and industries, and also
come from newer "emerging" industries. These emerging industries develop
quickly around new technologies and market opportunities. We believe our
emerging growth research team provides us a competitive advantage in
identifying and understanding these industries and companies before may of our
competitors on Wall Street.
 
  One such emerging sector we have identified is Information Technology
Education. An opportunity has developed for companies to provide training and
education in a wide range of software programs. In the past many companies
would maintain an IT training capability in house. However, today many
companies now look to hire an information technology provider to train their
employees on an as needed basis. We own a number of companies that provide this
capability including Strayer Education and Education Management Corp.
 
  A resurgence in the Lodging industry has created an improved operating
environment for established and new players in the sector. We are attracted to
several companies in this sector, including Four Seasons Hotel Corporation.
Four Seasons operates hotels at the highest end of the luxury segment where
there is little competition and a finite supply of rooms. This gives Four
Seasons strong pricing power. Room rates in many of their properties have risen
throughout the year, helping to improve profitability.
 
  In conclusion, we are pleased to manage a portfolio in the exciting area of
emerging growth companies. We look forward to our continued dialogue with Penn
Mutual and your clients.

PENN SERIES FUNDS, INC.
NOTES TO FINANCIAL STATEMENTS - JUNE 30, 1997 (UNAUDITED)
- --------------------------------------------------------------------------------
1 - SIGNIFICANT ACCOUNTING POLICIES
 
  Penn Series Funds, Inc. (Penn Series) was incorporated in Maryland on April
22, 1982. Penn Series is registered under the Investment Company Act of 1940,
as amended, as an open-end, diversified management investment company.
 
  Penn Series is presently offering shares in its Money Market, Quality Bond,
High Yield Bond, Growth Equity, Value Equity, Flexibly Managed, International
Equity, Small Capitalization and Emerging Growth Funds (the Funds). It is
authorized under its Articles of Incorporation to issue a separate class of
shares in one additional fund. The Fund would have its own investment objective
and policy.
 
  The following is a summary of significant accounting policies followed by
Penn Series in the preparation of its 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 amounts of assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from these estimates.
 
  INVESTMENT VALUATION:
  MONEY MARKET FUND - Investments in securities are valued under the amortized
cost method, which approximates current market value. Under this method,
securities are valued at cost on the date of purchase and thereafter a
proportionate amortization of any discount or premium until maturity is
assumed. Penn Series has agreed to maintain a dollar weighted average portfolio
maturity appropriate to the objective of maintaining a stable net asset value
per share. The Penn Series Board of Directors (The Board) has established
procedures reasonably designed to stabilize the net asset value per share for
purposes of sales and redemptions at $1.00. The Board performs regular review
and monitoring of the valuation in an attempt to avoid dilution or unfair
results to shareholders.
 
  QUALITY BOND, HIGH YIELD BOND, GROWTH EQUITY, VALUE EQUITY, FLEXIBLY MANAGED,
INTERNATIONAL EQUITY, SMALL CAPITALIZATION AND EMERGING GROWTH FUNDS -
 Portfolio securities listed on a national securities exchange are valued at
the last sale price on the securities exchange or securities market on which
such securities primarily are traded or, if there has been no sale on that day,
at the mean between the current closing bid and asked prices. All other
securities for which over-the-counter market quotations are readily available
will be valued on the basis of the mean between the last current bid and asked
prices. When market quotations are not readily available, or when restricted or
other assets are being valued, the securities or assets will be valued at fair
value as determined by The Board.
 
  The high yield securities in which the High Yield Bond Fund may invest are
predominantly speculative as to the issuer's continuing ability to meet
principal and interest payments. The value of the lower quality securities in
which the High Yield Bond Fund may invest will be affected by the credit
worthiness of individual issuers, general economic and specific industry
conditions, and will fluctuate inversely with changes in interest rates. In
addition, the secondary trading market for lower quality bonds may be less
active and less liquid than the trading market for higher quality bonds.
 
  FOREIGN CURRENCY TRANSLATION - The books and records of the Funds are
maintained in U.S. dollars. Foreign currency amounts are translated into U.S.
dollars on the following basis: market value of investment securities, assets
and liabilities at the current rate of exchange; and purchase and sales of
investment securities, income and expenses at the relevant rates of exchange
prevailing on the respective dates of such transactions.
 
  The Funds do not isolate that portion of realized and unrealized gains and
losses on investments in equity securities which are due to changes in the
foreign exchange rate from that which is due to changes in market prices of
equity securities.
 
  Foreign security and currency transactions may involve certain considerations
and risks not typically associated with those of U.S. dollar denominated
transactions as a result of, among other factors, the level of governmental
supervision and regulation of foreign securities markets and the possibility of
political or economic instability.
 
  SECURITY TRANSACTIONS AND INVESTMENT INCOME: Security transactions are
accounted for on the trade date. Dividend income is recorded on the ex-dividend
date and interest income is accrued as earned. The cost of investment
securities sold is determined by using the specific identification method for
both financial reporting and income tax purposes.
 
  DIVIDENDS TO SHAREHOLDERS: Dividends of investment income and realized
capital gains of the Quality Bond, High Yield Bond, Growth Equity, Value
Equity, Flexibly Managed, International Equity Small Capitalization and
Emerging Growth Funds will be declared and paid annually. Dividends of net
investment income of the Money Market Fund are declared daily and paid monthly.
Income distributions and capital gain distributions are determined in
accordance with income tax regulations which may differ from generally accepted
accounting principles. These differences are primarily due to differing
treatments for mortgage-backed securities, market discount and foreign currency
transactions.
 
  FEDERAL INCOME TAXES: It is the policy of each of the Funds to comply with
the requirements of the Internal Revenue Code applicable to regulated
investment companies and to distribute all of its taxable income, including
realized gains, to its shareholders. Therefore, no provision is made for
federal income or excise taxes.

2 - DERIVATIVE FINANCIAL INSTRUMENTS
 
OFF-BALANCE SHEET RISK
 
  The Funds may trade financial instruments with off-balance sheet risk in the
normal course of investing activities and to assist in managing exposure to
market risks such as interest rates and foreign currency exchange rates. These
financial instruments include written options, forward foreign currency
exchange contracts and futures contracts.
 
  The notional or contractual amounts of these instruments represent the
investment the Funds have in particular classes of financial instruments and do
not necessarily represent the amounts potentially subject to risk. The
measurement of the risks associated with these instruments is meaningful only
when all related and offsetting transactions are considered.
 
DERIVATIVE FINANCIAL INSTRUMENTS HELD OR ISSUED FOR PURPOSES OTHER THAN TRADING
 
  FUTURES CONTRACTS - Each of the Funds, other than Money Market, may enter
into financial futures contracts for the delayed delivery of securities,
currency or contracts based on financial indices on a future date. A Fund is
required to deposit either in cash or securities an amount equal to a certain
percentage of the contract amount. Subsequent payments are made or received by
a Fund each day, dependent on daily fluctuations in the value of the underlying
security, and are recorded for financial statement purposes as unrealized gains
or losses by a Fund. A Fund's investment in financial futures contracts is
designed only to hedge against anticipated future changes in interest or
exchange rates. Should interest or exchange rates move unexpectedly, a Fund may
not achieve the anticipated benefits of the financial futures contracts and may
realize a loss. There were no open futures contracts at June 30, 1997.
 
  WRITTEN OPTIONS - Each of the Funds, other than Money Market, may write
covered calls. Additionally, each of the Funds may buy put or call options for
which premiums are paid whether or not the option is exercised. Premiums
received from writing options which expire are treated as realized gains.
Premiums received from writing options which are exercised or are closed are
offset against the proceeds or amount paid on the transaction to determine the
realized gain or loss. If a put option is exercised, the premium increases the
cost basis of the securities purchased by a Fund. As writer of an option, the
Fund may have no control over whether the underlying securities may be sold
(call) and, as a result, bears the market risk of an unfavorable change in the
price of the securities underlying the written option. The Flexibly Managed
Fund has entered into put options during the period ended June 30, 1997.
Purchased put options open and outstanding at June 30, 1997 are disclosed in
the schedule of investments.
 
  FORWARD FOREIGN CURRENCY CONTRACTS - The Funds may enter into forward foreign
currency exchange contracts as a way of managing foreign exchange rate risk. A
Fund may enter into these contracts to fix the U.S. dollar value of a security
that it has agreed to buy or sell for the period between the date the trade was
entered into and the date the security is delivered and paid for. A Fund may
also use these contracts to hedge the U.S. dollar value of securities it
already owns denominated in foreign currencies.
 
  Forward foreign currency contracts are valued at the forward rate, and are
marked-to-market daily. The change in market value is recorded by the Fund as
an unrealized gain or loss. When the contract is closed, the Fund records a
realized gain or loss equal to the difference between the value of the contract
at the time it was opened and the value at the time it was closed.
 
  The use of forward foreign currency contracts does not eliminate fluctuations
in the underlying prices of the Fund's portfolio securities, but it does
establish a rate of exchange that can be achieved in the future. Although
forward foreign currency contracts limit the risk of loss due to a decline in
the value of the hedged currency, they also limit any potential gain that might
result should the value of the currency increase. In addition, the Funds could
be exposed to risks if the counterparties to the contracts are unable to meet
the terms of their contracts. The Flexibly Managed and International Equity
funds have entered into forward foreign currency contracts for the period ended
June 30, 1997.
 
  At June 30, 1997 there were no open contracts in the Flexibly Managed Fund.
Open forward foreign currency contracts held by the International Equity Fund
at June 30, 1997 were as follows:
