                                GROWTH PORTFOLIO
 
MONTAG & CALDWELL, INC.
ATLANTA, GEORGIA
 
Investment Management
 
     Montag & Caldwell manages approximately $25 billion for institutional
clients, and its normal investment minimum is $40 million.
 
Investment Objective
 
     The objective of the Growth Portfolio is to seek appreciation of capital
primarily through investments in common stocks.
 
Investment Philosophy
 
     The equity selection process is a low-risk, growth stock approach.
Valuation is the key selection criterion that makes its investment style
risk-averse. Montag & Caldwell also emphasizes growth characteristics because it
seeks not only companies with shares that are attractively priced but also those
that may experience strong earnings growth relative to other companies.
 
Performance Review for the Month Ended December 31, 1998
 
     The Growth Portfolio commenced operations on December 1, 1998. The S&P 500
Index returned 5.76 percent for the month ended December 31, 1998 versus 5.40
percent for the Growth Portfolio. Due to the short history of the Portfolio,
Montag's strategy for 1998 was to make initial investments of the net assets of
the Portfolio. At December 31, 1998, the Portfolio was approximately 74 percent
invested. During the month of December, technology and consumer growth issues in
the Portfolio performed particularly well.

Future Investment Strategy
 
     Given Montag's outlook for sustained growth in the economy with low
inflation, Montag believes that it may be another positive year for investors.
Montag expects corporate profit growth to remain subdued and bond yields to
remain fairly steady in the year ahead, and for stock market returns to be more
moderate than in 1998. These returns may approximate 10 percent when measured by
such popular stock market averages as the S&P 500 Index and the Dow Jones
Industrials.
 
     An economic setting of moderate corporate profit gains and steady bond
yields bodes well for the shares of growth companies that should produce
superior earnings growth. With the U.S. economy likely to slow and foreign
currencies strengthening against the dollar, Montag believes high-quality,
global consumer growth companies are particularly attractive investments. Given
the consistent demand for their products and favorable demographic trends,
health care companies may continue to do well. Selected technology holdings that
are benefiting from new product cycles and better worldwide industry conditions
may also be rewarding investments.

RETIREMENT SYSTEM INVESTORS INC.
NEW YORK, NEW YORK
 
Investment Management
 
     Retirement System Investors Inc. ("RSI") manages approximately $597 million
for all of its clients.
 
Investment Objective
 
     The objective of the Growth and Income Portfolio is a total return in
excess of the total return of the Lipper Growth and Income Mutual Funds Index
measured over a period of three to five years, by investing primarily in a
broadly diversified group of large-capitalization stocks.
 
Investment Philosophy
 
     RSI uses a fundamental analysis approach, including both qualitative and
quantitative factors, applied to a universe of well-established companies. The
portfolio manager seeks to identify reasonable valuations among this group of
stocks. Forward earnings projections and relative valuation parameters are used
to determine price objectives and return potential.
 
Performance Review for the Month Ended December 31, 1998
 
     The Growth and Income Portfolio commenced operations on December 1, 1998.
The S&P 500 Index returned 5.76 percent for the month ended December 31, 1998
versus 2.20 percent for the Growth and Income Portfolio. Due to the short
history of the Portfolio, RSI's strategy for 1998 was to make initial
investments of the net assets of the Portfolio. At December 31, 1998, the
Portfolio was approximately 65 percent invested.

Future Investment Strategy
 
     With the market at record valuation levels and an expected earnings
slowdown, RSI is placing more emphasis on controlling portfolio risk while
patiently seeking opportunities where its disciplines find them. Market breadth
will broaden during the year, which should benefit the Growth and Income
Portfolio, given its ample representation in value-type issues, which have
previously lagged the market.
 
     RSI expects to maintain its relatively large concentration in broad
technology growth areas, but most new purchases will be in lower
price-to-earnings, value/growth type companies that have lagged the market and
now seem attractive on a risk/return basis.

                                EQUITY PORTFOLIO
 
OPCAP ADVISORS, INC.
NEW YORK, NEW YORK
 
Investment Management
 
     OpCap Advisors, a wholly owned subsidiary of Oppenheimer Capital, has been
portfolio manager to this portfolio since inception. Oppenheimer Capital manages
approximately $62 billion for institutional clients, and its normal investment
minimum is $20 million.
 
Investment Objective
 
     The objective of the Equity Portfolio is long-term capital appreciation
primarily from investments in securities of companies that are believed by the
portfolio manager to be undervalued in the marketplace in relation to factors
such as the companies' assets or earnings.
 
Investment Philosophy
 
     OpCap Advisors' investment process uses a fundamental, bottom-up process of
value investing. The security selection process focuses on well-positioned
companies that generate high returns on assets and free cash flow, have strong
barriers to competition, have managements oriented to shareholder interests, and
sell at reasonable valuation levels. A complete qualitative review of the
business relative to its peers and its history is the key to the process. OpCap
seeks securities whose undervaluation is great enough to provide significant
upside reward with modest downside risk.
 
1998 Performance Review
 
     The stock market continued its remarkable advance in 1998, with the S&P 500
Index providing a total return of 28.6 percent, inclusive of reinvested
dividends. This marked the fourth consecutive year in which the index has
delivered a total return of more than 20 percent. The market has benefited
throughout this period from an unusually favorable U.S. economic environment of
moderate growth with declining interest rates and extremely low inflation.
 
     Beneath the surface, however, there were many crosscurrents in 1998. The
year's sharp increase for the S&P 500 Index was driven primarily by a limited
group of super-large company stocks. Many other stocks were left behind. For
instance, the Russell 2000 Index, a benchmark of small company stocks, actually
declined 2.6 percent in 1998. The strong relative performance of large versus
small stocks reflected the preference of many investors for highly liquid large
issues -- especially those with predictable earnings -- at a time when the
international economic outlook was uncertain and widespread concern existed that
the rate of economic growth in the U.S. might finally be slowing.
 
     In addition, there was a wide disparity between the performance of growth
stocks (those projected to have high
future earnings growth rates) and value stocks (those considered to be
undervalued in relation to their inherent worth). The
S&P 500/BARRA Growth Index rose 42.2 percent in 1998 while the S&P 500/BARRA
Value Index increased only 14.7 percent.
 
     Performance gaps of this type, favoring either growth or value, are common.
Nonetheless, the 1998 differential was one of the largest in history. Many
quality stocks that were inexpensive languished or even fell in price, while
some highly valued growth stocks became even more expensive. For instance, the
10 greatest contributors to the S&P 500 Index in 1998 advanced an average of
82.4 percent, reaching an average multiple of 46.7 times trailing earnings.
 
     Value investors had a difficult year. OpCap underperformed the market for
several reasons. For one, it owns the stocks of a diverse group of large and
mid-sized companies, and mid-cap stocks did not perform nearly as well as did
the S&P 500 Index, which is dominated by larger companies. In addition, the
performance of the market in 1998 was driven primarily by large "growth" stocks,
reflecting a preference of many investors for owning highly liquid
issues -- especially those with predictable earnings -- in an uncertain global
economic environment. Year-to-date performance differentials between value and
growth styles of investing are common, and OpCap is confident the pendulum will
swing back to value investing in time.
 
     In addition, with its risk-averse investment philosophy, OpCap sometimes
trails the market averages in periods of sharply rising prices. The portfolio
manager focuses on long-term investments in quality companies rather than on
attempting to predict near-term market trends.

     The average price-to-earnings ratio of the stocks owned by the portfolio
was 18.6 at the end of December, compared with a price-to-earnings ratio of 26.7
for the S&P 500 Index, indicating the relative value of the portfolio's
holdings. In contrast to their low relative valuations, the stocks owned by the
portfolio are expected to generate returns on equity that are well above the
average returns of the S&P 500 Index stocks. This combination of low relative
stock market prices and superior business characteristics helps control risk and
creates opportunity for investment profit.

                  Enterprise performance numbers do not include variable account
                  expenses. Remember that historic performance does not predict
                  future performance. The investment returns and principal value
                  will fluctuate so that an investor's shares, when redeemed,
                  may be worth more or less than their original cost.
 
                * The S&P 500 Index is an unmanaged index that includes 500
                  companies that tend to be leaders in important industries
                  within the U.S. economy. It includes reinvested dividends and
                  excludes any transaction or holding charges. Lipper Inc. is an
                  independent reporting service that measures the performance of
                  most mutual funds. The performance results reflect an
                  unchanged index and are net of all expenses other than sales
                  charges and redemption fees. One cannot invest directly in an
                  index.
 
Future Investment Strategy
 
     As for the prospects of the U.S. economy in 1999, the outlook is more
challenging than is usually the case. OpCap expects capital spending and rates
of inventory growth to slow and corporate profits to be mixed, with the
potential for downside surprises as deflationary pressures and rapid changes
derail profits at some companies. Clearly, these are negatives for the stock
market.
 
     On the other hand, the Federal Reserve Board has been cutting interest
rates and adding money to the economy at an explosive rate, helping drive the
stock market's strong performance in the fourth quarter of 1998. Given its
concern about the health of international financial markets, the Fed is likely
to persist in rapid monetary growth. Monetary stimulus and lower interest rates
could therefore continue to benefit financial markets, housing and personal
consumption in the coming year.
 
     In terms of the economic problems being experienced internationally,
renewed economic growth in Japan is a key part of the solution. Japanese banks
still must rid their books of enough bad loans to be considered healthy and to
contribute actively to financing economic growth. Even with government fiscal
stimulus programs, it is likely that the Japanese economy will decline slightly
this year. Europe is in much better shape, although its economic growth may slow
in 1999 as exports and capital spending are negatively affected by external
events. Severe economic problems still exist in the developing world, especially
in Latin America.
 
     OpCap continues to see many long-term positives, including powerful trends
such as an information revolution that is transforming the way every business
works, continued growth in demand for stocks from the Baby Boomers saving for
retirement, a federal budget surplus and no inflation. Nonetheless, OpCap is
concerned about the high valuation levels of many stocks.
 
     The challenge for investors in the coming year will be to chart a course
that captures favorable returns while guarding against the economic and market
uncertainty that exists at this time. Through its disciplined value philosophy,
OpCap seeks to do just that by owning businesses that generate high levels of
cash and use that cash to create value for shareholders through all economic
environments.
 
     The views expressed in this report reflect those of the portfolio manager
only through the end of the period of the report as stated on the cover. The
manager's views are subject to change at any time based on market and other
conditions.

                            EQUITY INCOME PORTFOLIO
 
1740 ADVISERS
NEW YORK, NEW YORK
 
Investment Management
 
     1740 Advisers manages more than $1.9 billion for institutional clients and
its normal investment minimum is $20 million.
 
Investment Objective
 
     The objective of the Equity Income Portfolio is to seek a combination of
growth and income to achieve an above-average and consistent total return,
primarily from investments in dividend-paying common stocks.
 
Investment Philosophy
 
     Above-average returns can be achieved by buying undervalued, out-of-favor
stocks and selling them after the market has recognized and corrected their
undervaluation. Dividend yield relative to the S&P 500 Index is the measure of
the value used in this strategy. It provides a disciplined approach to buy and
sell decisions, enhances stability in the portfolio, and lessens overall market
risk.
 
Performance Review for the Month Ended December 31, 1998
 
     The Equity Income Portfolio commenced operations on December 1, 1998. The
S&P Barra/Value Index returned 3.51 percent for the month ended December 31,
1998 versus 1.80 percent for the Equity Income Portfolio. Due to the short
history of the Portfolio, 1740 Advisers' strategy for 1998 was to make initial
investments of the net assets of the Portfolio. At December 31, 1998, the
Portfolio was approximately 80 percent invested.

                   Enterprise performance numbers do not include variable
                   account expenses. Remember that historic performance does not
                   predict future performance. The investment returns and
                   principal value will fluctuate so that an investor's shares,
                   when redeemed, may be worth more or less than their original
                   cost.
                 * The S & P Barra/Value Index is an unmanaged index that
                   includes reinvested dividends and excludes transaction and
                   holding charges. Lipper Inc. is an independent reporting
                   service that measures the performance of most mutual funds.
                   The performance results reflect an unmanaged index and are
                   net of all expenses other than sales charges and redemption
                   fees. One cannot invest directly in an index.

Future Investment Strategy
 
     The question for stock market valuation in 1999 will be whether the market
losses from lower earnings are offset by what it gains from lower rates. As of
now the answer seems to be positive. As long as rates stay low, and earnings are
stable, the flow of money into equity portfolios should continue. Valuations are
high, parts of the world are still fragile and, after four very strong years,
the market is entitled to a breather.
 
     With the expectation for slower economic growth, low inflation and lack of
pricing power and uncertain earnings, selectivity becomes important. In this
environment companies that can achieve unit growth and who do not need price
increases to succeed should be favored. This means an emphasis on health
care -- pharmaceuticals, hospital supplies and telecommunications -- primarily
telephones. Selected industrial names such as General Electric, Xerox and Pitney
Bowes should also do well. Financials -- banks and insurance -- should benefit
from lower interest rates.
 
     At the other end of the spectrum from the stable growers are the
economy-sensitive or cyclical stocks. The economic backdrop seems all wrong for
them, but that is already well known and is reflected in their very depressed
prices. If Southeast Asia stabilizes and shows any signs of improvement, the
energy, basic materials and capital good stocks which were hurt the most by the
economic crisis should benefit. The portfolio is slowly increasing exposure to
international oil, paper, forest products and chemical stocks. It may be early,
but usually these groups move in anticipation of a change in the world outlook.
 
     The views expressed in this report reflect those of the portfolio manager
only through the end of the period of the report as stated on the cover. The
manager's views are subject to change at any time based on market and other
conditions.

PROVIDENT INVESTMENT COUNSEL, INC.
PASADENA, CALIFORNIA
 
Investment Management
 
     Provident Investment Counsel manages approximately $20 billion for
institutional clients, and its usual investment minimum is $5 million.
 
Investment Objective
 
     The objective of the Capital Appreciation Portfolio is to seek maximum
capital appreciation, primarily through investment in common stock of companies
that demonstrate accelerating earnings momentum and consistently strong
financial characteristics.
 
Investment Philosophy
 
     Provident's investment philosophy is based on the belief that, over time,
the reason the price of a company's stock increases is because its earnings are
increasing. The investment strategy seeks to create a portfolio of companies
that, in aggregate, is growing its earnings at a faster and more consistent rate
than is the overall market.
 
Performance Review for the Month Ended December 31, 1998
 
     The Capital Appreciation Portfolio commenced operations on December 1,
1998. The S&P Barra/Growth Index returned 7.61 percent for the month ended
December 31, 1998 versus 11.40 percent for the Capital Appreciation Portfolio.
Due to the short history of the Portfolio, Provident's strategy for 1998 was to
make initial investments of the net assets of the Portfolio. At December 31,
1998, the Portfolio was approximately 61 percent invested.
 
     The Capital Appreciation Portfolio can attribute its superior first month
performance to several factors that Provident thinks will continue to provide
good relative returns. First, the portfolio manager emphasized the retail sector
given its strong outlook on consumer spending. Next, the Portfolio benefited
from technology services stocks. While 1998 may have been an exceptionally
volatile year for technology names, especially given their exposure to foreign
markets, the software side posted phenomenal gains, mostly in the fourth
quarter. The Portfolio contained names such as America Online, Fiserv and Lycos.
Finally, the dramatic underweighting in the consumer non-durable sectors helped
portfolio performance. Much of this sector was overly exposed to multinational
markets, and the Portfolio has purchased only two of these stocks: Infinity
Broadcasting and Outdoor Systems.

                    Enterprise performance numbers do not include variable
                    account expenses. Remember that historic performance does
                    not predict future performance. The investment returns and
                    principal value will fluctuate so that an investor's shares,
                    when redeemed, may be worth more or less than their original
                    cost.
                  * The S&P 500 Index is an unmanaged index that includes 500
                    companies that tend to be leaders in important industries
                    within the U.S. economy. It includes reinvested dividends
                    and excludes transaction and holding charges. Lipper Inc. is
                    an independent reporting service that measures the
                    performance of most mutual funds. The performance results
                    reflect an unmanaged index and are net of all expenses other
                    than sales charges and redemption fees. One cannot invest
                    directly in an index.
 
Future Investment Strategy
 
     Given the low inflation environment in the U.S. with stronger wage growth
and record low savings rates, the portfolio will continue to emphasize retail
into 1999. Emphasis will be on only the highest-quality, "best in class"
technology names with superior fundamentals, market shares, proprietary products
and solid management. The Capital Appreciation Portfolio will continue to seek
companies with quality of operations and earnings in both the large and
mid-capitalization markets.
 
     The views expressed in this report reflect those of the portfolio manager
only through the end of the period of the report as stated on the cover. The
manager's views are subject to change at any time based on market and other
conditions.

                         SMALL COMPANY GROWTH PORTFOLIO
 
WILLIAM D. WITTER, INC.
NEW YORK, NEW YORK
 
Investment Management
 
     William D. Witter, Inc. manages approximately $905 million in assets under
management and has a normal investment minimum for a separate account of $1
million.
 
Investment Objective
 
     The objective of the Small Company Growth Portfolio is to seek capital
appreciation by investing primarily in common stocks of small-capitalization
companies believed by the portfolio manager to have an outlook for strong
earnings growth and potential for significant capital appreciation.
 
Investment Philosophy
 
     William D. Witter will seek out stocks of small companies that are expected
to have above-average growth in earnings, which are reasonably valued. The
manager uses a disciplined approach in evaluating growth companies. It relates
the expected growth rate in earnings to the price-to-earnings ratio of the
stock. Generally, the manager will not buy a stock if the price-to-earnings
ratio exceeds the growth rate. By using this valuation parameter, the manager
believes it moderates some of the inherent volatility in the small
capitalization sector of the market. Securities will be sold when the manager
believes the stock price exceeds the valuation criteria or when the stock
appreciates to the point where it is substantially overweighted in the portfolio
or when the company no longer meets expectations. The manager's goal is to hold
a stock for a minimum of one year but this may not always be feasible and there
may be times when short-term gains or losses will be realized.
 
1998 Performance Review for the Month Ended December 31, 1998
 
     The Small Company Growth Portfolio commenced operations on December 1,
1998. The Russell 2000 Index returned 6.19 percent for the month ended December
31, 1998 versus 9.20 percent for the Small Company Growth Portfolio. Due to the
short history of the Portfolio, William D. Witter's strategy for 1998 was to
make initial investments of the net assets of the Portfolio. At December 31,
1998, the Portfolio was approximately 79 percent invested.
 
     William D. Witter's investment approach is growth at a reasonable price.
The portfolio manager, therefore, utilizes both cyclical and secular growth
securities. For instance, an investment was made in the semi-conductor company
Cymer, Inc., which has dynamic, long-term growth prospects but is subject to
industry-specific, cyclical influences. Simultaneously, an investment was made
in National Computer Systems, a provider of testing and computer services to
educational institutions, which has a very consistent record of sales and
earnings increases.
 
     During December, a positive contribution to the results was made by Ryanair
Holdings, a Dublin-based discount airline which should benefit significantly
from the opportunities to compete with formerly state-owned high-cost carriers.
The computer software companies collectively appreciated 55 percent during the
month.

                   Enterprise performance numbers do not include variable
                   account expenses. Remember that historic performance does not
                   predict future performance. The investors returns and
                   principal value will fluctuate so that an investor's shares,
                   when redeemed, may be worth more or less than their original
                   cost.
                 * The Russell 2000 Index is an unmanaged index that includes
                   reinvested dividends and excludes transaction and holding
                   charges. Lipper Inc. is an independent reporting service that
                   measures the performance of most mutual bonds. The
                   performance results reflect an unmanaged index and are net of
                   all expenses other than sales charges and redemption fees.
                   One cannot invest directly in an index.
 
Future Investment Strategy
 
     A continuation of 2.5 percent to 3 percent economic growth rate is
anticipated. While new obstacles such as the current crisis in Brazil are
undoubtedly going to appear, the combination of the capital investments and
restructuring decisions of the late 1980s and of the 1990s has created a
positive environment.
 
     Several of the keys to the recent and, Witter believes, future growth are
the productivity improvements associated with new technologies for use in
industry, commerce and telecommunications. Consequently, Witter shall continue
to look for investment opportunities in the technology sector.
 
     Due to higher valuation levels, positions in some of the software holdings
may be reduced. The semi-conductor equipment sector appears to have strong
fundamentals beginning in the year 2000. Additions may be made to the Portfolio
in this area. Some commercial service providers such as Charles River Associates
have substantial opportunities for both exceptional revenue and earnings growth.
This sector as well as health care are ones that Witter expects to expand. While
it appears early, oil service issues are being reviewed as future portfolio
additions.
 
     The views expressed in this report reflect those of the portfolio manager
only through the end of the period of the report as stated on the cover. The
manager's views are subject to change at any time based on market and other
conditions.

                         SMALL COMPANY VALUE PORTFOLIO
 
GABELLI ASSET MANAGEMENT COMPANY
RYE, NEW YORK
 
Investment Management
 
     Gabelli Asset Management Company, which manages more than $7.2 billion for
institutional clients and whose normal investment minimum is $500,000, became
manager of the portfolio on June 1, 1996.
 
Investment Objective
 
     The objective of the Small Company Value Portfolio is to seek maximum
capital appreciation, primarily through investment in the equity securities of
companies that have a market capitalization of no more than $1 billion.
 
Investment Philosophy
 
     Gabelli Asset Management Company's focus is on free cash flow, which it
believes to be the best barometer of a business' value. Rising free cash flow
often foreshadows net earnings improvement. Gabelli also looks at long-term
earnings trends, and analyzes on and off balance sheet assets and liabilities.
Gabelli wants to know everything and anything that will add or detract from its
private market value estimates. Finally, Gabelli looks for a
catalyst -- something happening in the company's industry or indigenous to the
company itself that will reveal value.
 
1998 Performance Review
 
     Small company stocks had a lackluster year, especially when compared to the
larger market indices. The last quarter of the year reversed the sharp
correction seen in the third quarter. The best performers in this portfolio were
media and communications companies. Price Communications, the cellular telephone
company, rose 372 percent. Cable company Century Communications rose 225
percent. Its affiliate telephone company, Centennial Cellular, was acquired and
resulted in a $200 million gain for Century. Data Broadcasting increased 218
percent for the year. The company plans an initial public offering of
MarketWatch, its business news and data web site.
 
     The largest portfolio holding, Cablevision, rose 109 percent. Cablevision
is one of the leading telecommunications and entertainment companies. Its
businesses include cable in the core media markets of New York, Boston and
Cleveland. It owns Madison Square Garden Properties, including the New York
Knicks and Rangers.
 
     Portfolio challenges were industrial companies that derive a portion of
their revenues from outside the U.S. These stocks were negatively impacted by
the sluggishness of the Southeast Asian economy. Companies such as
Aeroquip-Vickers, Flowserve, and Daniel Industries were poor performers, as were
issues such as Pioneer Group, Watts Industries and TVX Gold.

                  Enterprise performance numbers do not include variable account
                  expenses. Remember that historic performance does not predict
                  future performance. The investment returns and principal value
                  will fluctuate so that an investor's shares, when redeemed,
                  may be worth more or less than their original cost.
 
                * The Russell 2000 Index is an unmanaged index. It includes
                  reinvested dividends and excludes any transaction or holding
                  charges. The Russell 2000 Index replaces the Russell 1000
                  Value Index as the broad-based comparison to the Small Company
                  Value Portfolio as it more appropriately reflects the
                  securities market in which the Portfolio invests. Lipper Inc.
                  is an independent reporting service that measures the
                  performance of most mutual funds. The performance results
                  reflect an unmanaged index and are net of all expenses other
                  than sales charges and redemption fees. One cannot invest
                  directly in an index.
 
                  During 1998, an investment in the above hypothetical
                  shareholder account increased $3,908 compared to a decrease of
                  $885 and an increase of $6,719 in the Russell 2000 Index and
                  Russell 1000 Value Index, respectively.
 
Future Investment Strategy
 
     Gabelli believes the four legs supporting the stock market stool are low
inflation, low interest rates, a powerful flow of funds and strong corporate
profit growth. While the first three remain very positive, there are doubts
about the fourth. Weak Asian markets and the ongoing international currency
crisis could lead to problems in the Latin American currencies. Serious economic
problems for the United States' Latin American trading partners would have a far
greater impact on the American economy and corporate profits than did economic
disruption in Southeast Asia.
 
     While the U.S. economy is starting to slow, it is still advancing at a
respectable pace. If Latin America remains stable and the American consumer
continues to spend, the U.S. economy may continue to expand, albeit at a slower
pace than in recent years.
 
     Gabelli will continue find many true business bargains in the small-cap
sector. These bargains present the opportunity for financially robust companies
to continue to snap up other companies in their own and related industries due
to necessity. For example, a telecommunications company that does not offer a
full range of services (long distance and local telephone Internet access and
transmission and home entertainment services) will likely have a very bleak
future. This bodes well for the portfolio during the coming year.
 
     The views expressed in this report reflect those of the portfolio manager
only through the end of the period of the report as stated on the cover. The
manager's views are subject to change at any time based on market and other
conditions.

                         INTERNATIONAL GROWTH PORTFOLIO
 
BRINSON PARTNERS, INC.
CHICAGO, ILLINOIS
 
Investment Management
 
     Brinson Partners, Inc., is a global investment management firm with offices
in Chicago, London and Tokyo. Brinson Partners manages approximately $163
billion for institutional clients, and its normal investment minimum is $25
million.
 
Investment Objective
 
     The objective of the International Growth Portfolio is to seek capital
appreciation, primarily through a diversified portfolio of non-U.S. equity
securities.
 
Investment Philosophy
 
     Brinson Partners believes that discrepancies exist between prices and
fundamental values, both across and within the international equity markets. It
takes advantage of these discrepancies by using a disciplined approach to
measure fundamental value from the perspective of the long-term investor. This
international equity strategy reflects the manager's decisions about the
relative attractiveness of the asset class, the individual equity markets,
currencies, the industries across and within those markets, other common risk
factors within those markets, and individual international companies.
 
1998 Performance Review
 
     Returns for non-U.S. markets were enhanced by foreign currency strength.
The notable exceptions were the Canadian dollar, as well as the Australian and
New Zealand dollars, all of which weakened relative to the U.S. dollar. The
Japanese yen strengthened sharply at the start of the fourth quarter, to end the
year in positive territory relative to the U.S. dollar.
 
     With upturns in the markets through the fourth quarter, the majority of
individual European markets ended the year with double-digit returns (in
dollar-hedged terms): Finland (110.75 percent) and Belgium (59.07 percent)
posted the strongest returns. Norway (-26.89 percent) and New Zealand (-16.22
percent) were the weakest performers, as were the Asian markets of Singapore
(-7.43 percent), Hong Kong (-6.28 percent) and Japan (-3.84 percent).
 
     For the year, currency allocation and market allocation detracted from
performance. The portfolio's overweight to the weak Australian and New Zealand
dollar currencies, as well as the underweight of the yen, hurt performance.
Security selection, particularly Japan stock selection, was a positive
contributor to performance for the year. Strategic cash held in the portfolio
detracted from performance in the first half of the year, otherwise market
allocation decisions overall provided favorable results.

                   Enterprise performance numbers do not include variable
                   account expenses. Remember that historic performance does not
                   predict future performance. The investment returns and
                   principal value will fluctuate so that an investor's shares,
                   when redeemed, may be worth more or less than their original
                   cost.
 
                   * The EAFE Index is an unmanaged index that includes
                     reinvested dividends and excludes transaction or holding
                     charges. Lipper Inc. is an independent reporting service
                     that measures the performance of most mutual funds. The
                     performance results reflect an unmanaged index and are net
                     of all expenses other than sales charges and redemption
                     fees. One cannot invest directly in an index.
 
Future Investment Strategy
 
     Monetary union, privatization/restructuring/merger activity and increased
capital flows have boosted European equity markets. Despite their excellent
performance, European corporations are still early into their restructuring,
with the potential for improving profitability ahead. Europe is the portfolio's
largest overweight. Most Pacific markets continued to suffer consequences of the
1997 currency crisis. This situation has been aggravated in Japan by flawed
macroeconomic policies, a largely insolvent financial sector and an unprofitable
domestic corporate sector. The portfolio remains very underweight compared to
Japan, Hong Kong and Singapore. In comparison, Australia and New Zealand have
been unduly impacted by their geographic proximity to Asia and are attractively
priced. The portfolio maintains overweight in these markets.
 
     Currency strategies within the portfolio at the end of the year remained
similar to that of the market allocations. The only notable hedging strategies
were the six percent underweight of the Japanese yen and a four percent
underweight of the British pound sterling. The Hong Kong dollar was also
underweight, such that there were no currency exposures to Hong Kong. Offsetting
these positions were overweights in the Australian dollar and to a lesser
degree, the New Zealand dollar.
 
     As with all international growth portfolios, the International Growth
Portfolio carries additional risks associated with possibly less stable foreign
securities and currencies, lack of uniform accounting standards and political
instability.
 
     The views expressed in this report reflect those of the portfolio manager
only through the end of the period of the report as stated on the cover. The
manager's views are subject to change at any time based on market and other
conditions.

                           HIGH-YIELD BOND PORTFOLIO
 
CAYWOOD-SCHOLL CAPITAL MANAGEMENT
SAN DIEGO, CALIFORNIA
 
Investment Management
 
     Caywood-Scholl manages approximately $973 million for institutional
clients, and its normal investment minimum is $1 million.
 
Investment Objective
 
     The objective of the High-Yield Bond Portfolio is to seek maximum current
income, primarily from debt securities that are rated Ba or lower by Moody's
Investors Service or BB or lower by Standard & Poor's.
 
Investment Philosophy
 
     Caywood-Scholl's investment philosophy of seeking relative value and
avoiding risk is credit research-driven. The discipline of credit research
facilitates the informed use of a variety of lower-rated securities in
aggressive fixed income investing.
 
1998 Performance Review
 
     The predominant theme in 1998 was volatility. After advancing more than
four percent during the first quarter, the high-yield market was derailed by
both global and domestic events; including spreading "Asian contagion," a
Russian default, the Long Term Capital Management bailout, deflating
commodities, and the impeachment process of the U.S. President. Whereas risk had
been in vogue with most investors for much of the 1990s, risk was abruptly out
of fashion. As a result, the high-yield market underperformed the Treasury
market.
 
     Despite the lackluster performance it should be noted that the high-yield
market had a record year in terms of new issuance and mutual fund inflows. The
market has grown to more than $550 billion. The scope of institutional investors
involved in the market has increased, as has the number of market makers.

                   Enterprise performance numbers do not include variable
                   account expenses. Remember that historic performance does not
                   predict future. The investment returns and principal value
                   will fluctuate so that an investor's shares, when redeemed,
                   may be worth more or less than their original cost.
 
                   * The Lehman BB Index is an unmanaged index that includes
                   reinvested interest and excludes transaction and holding
                   charges. Lipper Inc. is an independent reporting service that
                   measures the performance of most mutual funds. The
                   performance results reflect an unmanaged index and are net of
                   all expenses other than sales charges and redemption fees.
                   One cannot invest directly in an index.

Future Investment Strategy
 
     Looking ahead to 1999, Caywood-Scholl believes that the valuation in the
high-yield market is still very attractive. With most economists predicting
domestic growth in the neighborhood of two percent, the portfolio manager does
not expect a meaningful increase in credit risk. The domestic bank sector is
healthy and should remain supportive to leveraged companies. A robust stock
market is always a positive for high-yield issuers, giving them an alternative
source of capital. Lastly, given the growth of the market and the general
improvement of the quality of issuers, it is easy to have a positive outlook on
the market.
 
     The views expressed in this report reflect those of the portfolio manager
only through the end of the period of the report as stated on the cover. The
manager's views are subject to change at any time based on market and other
conditions.

OPCAP ADVISORS, INC.
NEW YORK, NEW YORK
 
Investment Management
 
     OpCap Advisors, a wholly owned subsidiary of Oppenheimer Capital, became
portfolio manager to the Managed Portfolio on October 1, 1994. Oppenheimer
Capital manages approximately $62 billion for institutional clients, and its
normal investment minimum is $20 million.
 
Investment Objective
 
     The objective of the Managed Portfolio is to seek growth of capital over
time through investment in a portfolio consisting of common stocks, bonds and
cash equivalents, the percentages of which will vary based on the manager's
assessment of relative investment values.
 
Investment Philosophy
 
     OpCap's investment process seeks to take advantage of opportunities in all
market sectors by shifting the investment mix among stocks, bonds and money
market instruments. The focus of the investment process is to identify quality
companies that are undervalued in the market. The average annual return on
equity of these companies is in excess of the average return on equity of the
companies in the S&P 500 Index, while the average price-to-earnings ratio of
these companies is significantly below the price-to-earnings ratio for those
companies. This combination of high returns on equity and low security
valuations helps preserve capital in down markets and provides opportunity for
investment profit over time.
 
1998 Performance Review
 
     1998 was not an especially good year for the portfolio. It trailed the S&P
500 Index because of two main factors: the minimal holdings of technology
issues, many of which had large gains in 1998, and the poor performance of
certain of the portfolio's investments, including Citigroup, Inc., and Boeing
Co. Other major holdings of the portfolio, including its three largest
holdings -- McDonald's Corp., Time Warner Inc. and Federal Home Loan Mortgage
Corp. (Freddie Mac) -- rose strongly.
 
     While the portfolio's 1998 results did not live up to expectations, OpCap
remains dedicated to the continued delivery of excellent results over time.
OpCap focuses on individual companies and tries to understand where their
businesses are going over the next several years, not on where the stock market
is heading in the next six months. Simply stated, OpCap wants to invest in
superior businesses that are underpriced in the stock market. A superior
business is one that is extremely well-managed, earns high returns on capital,
has a dominant competitive position to protect those returns and uses the free
cash flow resulting from those returns to create shareholder value, such as
through astute acquisitions or share repurchases.

                 Enterprise performance numbers do not include variable account
                 expenses. Remember that historic performance does not predict
                 future performance. The investment returns and principal value
                 will fluctuate so that an investor's shares, when redeemed, may
                 be worth more or less than their original cost.
 
                * The S&P 500 Index is an unmanaged index that includes 500
                  companies that tend to be leaders in important industries
                  within the U.S. economy. It includes reinvested dividends and
                  excludes any transactions or holding charges. Lipper Inc. is
                  an independent reporting service that measures the performance
                  of most mutual funds. The performance results reflect an
                  unmanaged index and are net of all expenses other than sales
                  charges and redemption fees. One cannot invest directly in an
                  index.
 
Future Investment Strategy
 
     OpCap expects U.S. and international economic growth to slow in 1999, and
the portfolio is positioned to perform well in this environment. The portfolio
owns very few cyclical stocks that would be hurt by economic weakness. New
investments in the fourth quarter were AlliedSignal Inc., a diversified
technology and manufacturing company; News Corporation Ltd., a global media and
communications company; and US West Inc., which provides telecommunications
services in the western and midwestern United States. OpCap believes each should
deliver strong business results in 1999.
 
     US West Inc. exemplifies the portfolio manager's philosophy of owning
quality companies with excellent prospects. It has been investing in new
technologies and businesses, and those investments should begin to pay off with
higher earnings. This includes the company's new wired-wireless service, the
first of its kind in the United States. The service allows customers to have a
single number for their wired and wireless phones.
 
The views expressed in this report reflect those of the portfolio manager only
through the end of the period of the report as stated on the cover. The
manager's views are subject to change at any time based on market and other
conditions.

                               DECEMBER 31, 1998
 
1. ORGANIZATION
 
     Enterprise Accumulation Trust (the "Trust") was organized as a
Massachusetts business trust and is registered under the Investment Company Act
of 1940 as a diversified, open-end management investment company. The Trust is
authorized to issue an unlimited number of shares of beneficial interest at $.01
par value for the following portfolios: Growth Portfolio, Growth and Income
Portfolio, Equity Portfolio, Equity Income Portfolio, Capital Appreciation
Portfolio, Small Company Growth Portfolio, Small Company Value Portfolio,
International Growth Portfolio, High-Yield Bond Portfolio and Managed Portfolio.
Prior to May 1, 1998 the Small Company Value Portfolio was known as the Small
Cap Portfolio.
 
     The Trust serves as an investment vehicle for MONYMaster and MONY Custom
Master, flexible payment variable annuity policy, and MONY Equity Master and
MONY Custom Equity Master, flexible premium variable universal life insurance
policies, issued by MONY Life of America ("MLOA") and MONY Life Insurance
Company, a wholly-owned subsidiary of MLOA. The Trust also serves as an
investment vehicle for a corporate-sponsored variable universal life product
issued by MONY America. The following is a summary of significant accounting
policies consistently followed by the Trust in the preparation of its financial
statements.
 
2. SIGNIFICANT ACCOUNTING POLICIES
 
     Valuation of Investments -- Growth Portfolio, Growth and Income Portfolio,
Equity Portfolio, Equity Income Portfolio, Capital Appreciation Portfolio, Small
Company Growth Portfolio, Small Company Value Portfolio, International Growth
Portfolio, High-Yield Bond Portfolio and Managed Portfolio: Investment
securities, other than debt securities, listed on either a national or foreign
securities exchange or traded in the over-the-counter National Market System are
valued each business day at the last reported sales price; if there are no such
reported sales, the securities are valued at their last quoted bid price. Other
securities traded over-the-counter and not part of the National Market System
are valued at the last quoted bid price. Debt securities (other than certain
short-term obligations) are valued each business day by an independent pricing
service approved by the Board of Trustees. Short-term debt securities having a
remaining maturity of sixty days or less are valued at amortized cost, which
approximates market value. Any securities for which market quotations are not
readily available are valued at their fair value as determined in good faith by
the Board of Trustees.
 
     Special Valuation Risk -- The high-yield securities in which the High-Yield
Bond Portfolio may invest may be considered speculative in regard to the
issuer's continuing ability to meet principal and interest payments. The value
of the lower rated securities in which the High-Yield Bond Portfolio 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.
 
     Repurchase Agreements -- Each Portfolio may acquire securities subject to
repurchase agreements. Under a typical repurchase agreement, a Portfolio would
acquire a debt security for a relatively short period (usually for one day and
not for more than one week) subject to an obligation of the seller to repurchase
and of the Portfolio to resell the debt security at an agreed-upon higher price,
thereby establishing a fixed investment return during the Portfolio's holding
period. Under each repurchase agreement, the Portfolio receives, as collateral,
securities whose market value (including interest) is at least equal to the
repurchase price. Repurchase agreements could involve certain risks in the event
of default or insolvency of the selling institution, including costs of
disposing of securities held as collateral and any loss resulting from delays or
restrictions upon the Portfolio's ability to dispose of securities.
 
     Futures Contracts -- Upon entering into such a contract, a Portfolio is
required to deposit with the broker an amount of cash or securities equal to the
minimum "initial margin" requirements of the exchange. Pursuant to the contract,
the Portfolio agrees to receive from or pay to the broker an amount of cash
equal to the daily fluctuation in the value of the contract. Such receipts or
payments, known as "variation margin," are recorded by the Portfolio as
unrealized appreciation or depreciation. When the contract is closed the
Portfolio records a realized gain or loss equal to the difference between the
value of the contract at the time it was opened and value at the time it was
closed. There were no open futures contracts held in any of the Portfolios at
December 31, 1998.

                         ENTERPRISE ACCUMULATION TRUST
 
                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
                               DECEMBER 31, 1998
 
     Foreign Currency Translation -- Securities, other assets and liabilities of
the International Growth Portfolio whose values are initially expressed in
foreign currencies are translated to U.S. dollars at the bid price of such
currency against U.S. dollars last quoted by a major bank. Receivables and
payables for dividend and interest income and certain expenses denominated in
foreign currencies are marked-to-market daily based on daily exchange rates and
exchange gains and losses are realized upon ultimate receipt or disbursement.
The International Growth Portfolio does not isolate that portion of its realized
and unrealized gains on investments from changes in foreign exchange rates from
fluctuations arising from changes in the market prices of the investments.
 
     Security Transactions and Other Income -- Security transactions are
accounted for on the trade date. Realized gains and losses from investment
transactions are determined on the basis of identical cost and realized gains
and losses from currency transactions are determined on the basis of average
cost. Dividend income received and distributions to shareholders are recognized
on the ex-dividend date, and interest income is recognized on the accrual basis.
Discounts or premiums on debt securities purchased are accreted or amortized to
interest income over the lives of the respective securities.
 
     Expenses -- Each portfolio bears expenses incurred specifically on its
behalf as well as a portion of the common expenses of the Trust.
 
     Federal Income Taxes -- No provision for Federal income or excise taxes is
required because the trust intends to continue to qualify as a regulated
investment company and distribute all of its taxable income to shareholders.
 
     Use of Estimates in Preparation of Financial Statements -- Preparation of
financial statements in conformity with generally accepted accounting principles
requires management to make estimates and assumptions that may 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 those estimates.
 
     Dividends and Distributions -- Growth Portfolio, Growth and Income
Portfolio, Equity Portfolio, Equity Income Portfolio, Capital Appreciation
Portfolio, Small Company Growth Portfolio, Small Company Value Portfolio,
International Growth Portfolio and Managed Portfolio: Dividends and
distributions to shareholders from net investment income and net realized
capital gains, if any, are declared and paid at least annually. The High-Yield
Bond Portfolio: Dividends from net investment income are declared daily and paid
monthly. Distributions from net realized capital gains, if any, are declared and
paid at least annually.
 
3. TRANSACTIONS WITH AFFILIATES
 
     The investment advisory fee is payable monthly to Enterprise Capital
Management, Inc. ("Enterprise Capital"), a wholly-owned subsidiary of MONY Life
Insurance Company, and is computed as a percentage of each Portfolio's net
assets as of the close of business each day and is as follows: for each of the
Equity, Small Company Value, and Managed Portfolios, .80% for the first $400
million, .75% for the next $400 million, and .70% for net assets over $800
million, 1.00% for the Small Company Growth Portfolio, 0.85% for the
International Growth Portfolio, 0.75% for each of the Growth, Capital
Appreciation, Growth and Income, and Equity Income Portfolios and 0.60% for the
High-Yield Bond Portfolio.
 
     Enterprise Capital has agreed to reimburse the Portfolios for expenses
incurred in excess of a percentage of average net assets. The percentages are as
follows: Growth -- 1.15%, Growth and Income -- 1.05%, Equity -- 1.15%, Equity
Income -- 1.05%, Capital Appreciation -- 1.30%, Small Company Growth -- 1.40%,
Small Company Value -- 1.30%, International Growth -- 1.55%, High-Yield
Bond -- .85% and Managed -- 1.30%.
 
     Enterprise Capital is a wholly-owned subsidiary of MONY Life Insurance
Company, which is wholly-owned by The MONY Group Inc. The MONY Group Inc. and
its subsidiaries and affiliates had the following investments in the Trust as of
December 31, 1998: Growth -- $263,500, Growth and Income -- $255,500, Capital
Appreciation -- $278,500, Small Company Growth -- $273,000, and Equity
Income -- $254,500.
 
     Enterprise Capital has entered into sub-advisory agreements with various
investment advisers as Portfolio Managers for the Trust. A portion of the
management fee received by Enterprise Capital is paid to the respective
Portfolio Manager. 1740 Advisers, Inc., a wholly-owned subsidiary of MONY Life
Insurance Company, is the Fund Manager for the Equity Income Fund. For the year
ended December 31, 1998, ECM incurred subadvisory fees payable to 1740 Advisers,
Inc. related to the Equity Income Fund of $70, with a related payable balance of
$70 as of December 31, 1998.

4. FINANCIAL INSTRUMENTS
 
     As part of its investment program, the International Growth Portfolio
utilizes forward currency exchange contracts to manage exposure to currency
fluctuations and hedge against adverse changes in connection with purchases and
sales of securities. The Portfolio enters into forward contracts only for
hedging purposes. At December 31, 1998, the International Growth Portfolio had
entered into various forward currency exchange contracts under which it is
obligated to exchange currencies at specified future dates. Risks arise from the
possible inability of counterparties to meet the terms of their contracts and
from movements in currency values. Outstanding contracts at December 31, 1998
are as follows:

</TABLE>
 
     As part of its investment program, the High-Yield Bond Portfolio enters
into futures contracts to hedge against anticipated future price and interest
rate changes. Risks of entering into futures contracts include: (1) the risk
that the price of the futures contracts may not move in the same direction as
the price of the securities in the various markets; (2) the risk that there will
be no liquid secondary market when the Portfolio attempts to enter into a
closing position; (3) the risk that the Portfolio will lose an amount in excess
of the initial margin deposit; and (4) the fact that the success or failure of
these transactions for the Portfolio depends on the ability of the Portfolio
Manager to predict movements in stock, bond, and currency prices and interest
rates. There were no open futures contracts at December 31, 1998 in the
High-Yield Bond Portfolio.
 
5. PURCHASES AND SALES OF SECURITIES

     Income 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
futures and options transactions, losses deferred due to wash sales, foreign
currency transactions, investments in passive foreign investment companies, and
excise tax regulations.
 
     Permanent book and tax basis differences relating to shareholder
distributions will result in reclassifications to paid in capital. Any taxable
gain remaining at fiscal year end is distributed in the following year.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Shareholders and Board of Trustees of
Enterprise Accumulation Trust:
 
     In our opinion, the accompanying statements of assets and liabilities,
including the portfolios of investments, and the related statements of
operations and of changes in net assets, and the financial highlights, present
fairly, in all material respects, the financial position of the Growth, Growth
and Income, Equity, Equity Income, Capital Appreciation, Small Company Growth,
Small Company Value, International Growth, High-Yield Bond and Managed
Portfolios of Enterprise Accumulation Trust (collectively the "Trust") at
December 31, 1998, the results of their operations for the year (or period) then
ended, the changes in their net assets for each of the two years (or periods) in
the period then ended, and the financial highlights for each of the periods
presented, in conformity with generally accepted accounting principles. These
financial statements and financial highlights (hereafter referred to as
"financial statements") are the responsibility of the Trust's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these financial statements in accordance
with generally accepted auditing standards which require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audits, which included confirmation of securities at
December 31, 1998 by correspondence with the custodian and brokers, provide a
reasonable basis for the opinion expressed above.
