TO OUR POLICYOWNERS:

period ended June 30, 1998. This Semi-Annual Report contains current performance

Series, Morgan Stanley Emerging Markets Equity, T. Rowe Price Equity Income and

MID-YEAR REVIEW
The United States stock market once again continued its robust pace during the
first half of 1998. The Dow Jones Industrial Average(2) gained another 13.2%,
following a 22.6% gain in 1997, 26.0% in 1996, and 33.5% in 1995. Growth
continued to exceed expectations, while inflation remained subdued. Real Gross
Domestic Product (GDP) grew at an astounding annual rate of 5.4% in the first
quarter, as the negative effects of the Asian crisis on net exports and
industrial production were more than offset by stellar consumer spending,
residential construction, business capital spending, and a quickened pace of
inventory investment. Growth seems to have been somewhat slower in the second
quarter as the final demand moderated, the trade deficit continued to widen, and
inventory investment dropped.
 
Over the rest of the year, the economy is expected to slow to a more sustainable
pace as excess inventory accumulation continues to be pared and weakness from
the trade and manufacturing sectors spreads to the rest of the economy.
Inflation should pick-up only slightly as oil prices stop declining and the
lagged effects of the higher dollar begin to dissipate. The unemployment rate
should begin to rise again as the economy slows, helping to moderate any rise in
inflation. On the positive side, the economic expansion in the United States is
likely to continue with no recession in sight, and interest rates should remain
low.
 
VARIABLE ANNUITIES IN GENERAL
The United States variable annuity industry set a record in 1997 with nearly $88
billion in sales, representing more than a 20% increase versus 1996 results.
Industry experts expect another stellar year in 1998.
 
Variable annuities are viewed as an effective financial vehicle to help
Americans live comfortably during their retirement years. In addition to
providing a choice of investment divisions from an array of cash, bond and
equity sectors covering markets throughout the United States and abroad,
variable annuities offer additional features and benefits including tax
deferral, an income for life, a guaranteed fixed interest account, and a death
benefit provision.
 
New York Life Insurance and Annuity Corporation (NYLIAC) recorded $1.01 billion
in variable annuity premiums during the first half of 1998, representing a 42%
increase versus the first half of 1997. There are many factors attributing to
NYLIAC's impressive variable annuities sales results including an impressive
equity market, a low interest rate environment, and solid product and marketing
support. Also, we've enhanced our investment options by recently adding eight
new investment divisions. We now have twenty-six investment divisions managed by
several of today's most well-known fund families.
 
COMMITMENT TO YOUR NEEDS
We thank you for selecting us to be "The Company You Keep(R)," and we look
forward to helping you build a solid foundation for your retirement years.

MAINSTAY VP SERIES FUND, INC. PORTFOLIOS
 
MACKAY-SHIELDS FINANCIAL CORPORATION
 
ADVISER'S REPORT
 
Market Overview
 
The equity market retreated from its blistering pace in the first quarter to
more modest advances in the second quarter, chiefly as a result of a more
sobering assessment of the Asian economic crisis. Any thoughts that the Asian
crisis would be a short-lived event have been put to rest. The main question now
is how will U.S. corporate profits fare in the second half of the year and in
1999? Most companies will soon report second-quarter earnings and give guidance
on future prospects. One thing is clear: the likely slowing of corporate profits
will be far from uniform. While the basic material, energy and
commodity-technology sectors appear most vulnerable, the consumer and healthcare
sectors continue to show signs of strength.
 
The second quarter of 1998 saw the market lose the wind at its back, with the
average general U.S. equity mutual fund losing 0.2% to 0.3% according to
Lipper(1) and Morningstar(2) with initial gains followed by losses. The S&P 500
Index(3) (with dividends) returned 3.30%, the Dow Jones Industrial Average(4)
returned 2.1% and NASDAQ(5) posted a 3.2% gain. The stock market has displayed
two characteristics over the past 18 months: a mix of strongly performing
quarters followed by sputtering quarters. The engine of the stock market did not
seem to be able to remain energized for more than three months before it took a
breath. Also, the narrowness of the best-performing part of the market has
remained markedly consistent. Investors fared best in blue chip investments such
as U.S. Treasury bonds and "nifty-fifty" type equity investments such as large
capitalization stocks with prospects of rising earnings. Smaller stocks and
investments in fundamentally cheaper "value" stocks were not rewarded in this
environment. In fact, as stocks got smaller or more value oriented, the
performance got worse for the quarter. As a result, S&P Index funds, emphasizing
the large-cap names that dominate the Index, have outshone active managers. The
only stock funds that outperformed the S&P during the quarter were large-cap
growth funds which returned 5.24%. During the second quarter, large cap blend
funds were up 2.12% and mid-cap growth funds posted a small gain of 0.87%.
 
The outperformance of the largest names in the S&P 500 is particularly notable
as these companies' earnings as a whole have been shrinking, are influenced by
currency depreciations outside the U.S., and may be greatly affected by the
continuing Asian financial crisis. The recent increase in wages could signal
coming inflation, which has been an insignificant factor for several years.
Fueling the market despite these weaknesses, these companies are also viewed by
investors as "safe havens" with expectations of lower volatility if the market
goes down. Also, because of their liquidity, investors believe large-cap blue
chips will be easier to sell in a market downturn.
 
On the fixed income side, the safest bonds and the funds that hold them
outperformed the riskier end of the spectrum. According to Lipper, general U.S.
Treasury funds posted a return of 2.92% for the quarter, A-rated corporate bonds
recorded gains of 2.36% for the period and tax-free funds had returns of 1.29%.
Interest rate declines help performance of the bond market because bond prices
rise as interest rates decline. This is in direct contrast to the average
emerging market bond fund which lost 7.7% in the second quarter and junk-bond
funds which gained a paltry 0.29%. This reflects a new cautiousness on the part
of investors, who added $6.2 billion into taxable bond funds in May, versus $3.6
billion in April. Municipal funds listed $2.4 billion in new investments in May,
versus $544 million in April. Foreign buyers continued their love affair with
U.S. bonds, despite the 30-year U.S. Treasury bond's lowest yield in several
years. Adding fuel to the fire, a positive Federal budget picture is sure to
decrease the supply of U.S. Treasuries, as the Government has less debt to
finance going forward.
 
Internationally, the second quarter was a tale of two markets. Investors in
developed markets fared far better than those who invested in emerging markets.
European markets embracing American production and management efficiencies are
soaring. According to Lipper, funds investing in Europe posted the most positive
results, on average returning 6.30% for the second quarter. On the other hand,
Asia's financial crisis is not over and is

spilling over into Latin America. The flight to quality and the American markets
have only exacerbated emerging market economic woes.
 
Looking forward, several factors are lurking which may hurt the robustness of
the U.S. economy. Increasing wages, which constitute two-thirds of the CPI(6),
may ignite inflation if productivity gains do not increase proportionately.
Also, the Asian financial crisis is not over. Many economists who participated
in The Wall Street Journal's latest semi-annual forecasting survey believe that
the brunt of the Asian crisis will hit the U.S. over the next several months,
causing growth to slow and unemployment to increase. However, on the positive
side, many Asian countries are facing the enormity of their respective
economies' problems and are taking steps to solve them. In the meantime, we
continue to enjoy low inflation, stable interest rates and steady growth -- key
ingredients for an ebullient economy.

NEW YORK LIFE INSURANCE COMPANY
 
ADVISER'S REPORT
 
Market Overview
 
The first half of 1998 has resulted in another period of attractive investment
returns for the U.S. financial markets, with particularly strong returns from
the stock market.
 
The U.S. economy continues to enjoy robust expansion -- with strong growth, low
inflation, a Federal budget surplus and a structurally sound economy. As a
result, the financial health of most U.S. firms remains strong. Overseas,
however, the Asian economy is suffering as many emerging Asian countries are
ravaged by currency devaluations, capital flight and heightened balance of
payment pressures. Near term, the crisis has caused a flight to quality to the
U.S. financial markets, bolstering values here. Longer term, the Asian crisis
will have a negative impact on the worldwide economy, particularly on U.S.
companies in commodity and export related industries.
 
The stock market has reached historically high price levels in both absolute and
relative terms. While corporate earnings growth has slowed, valuation levels
have increased as interest rates have declined and merger and acquisition
activity has increased.
 
The bond market produced returns in line with interest income and modest price
appreciation. The modestly lower interest rate environment has caused spreads to
widen on mortgage-backed securities and corporate bonds due to prepayment
concerns and unprecedented new issue supply as corporations sought to lock-in
lower financing costs.
 
Looking forward for the rest of the year, we anticipate a stable monetary policy
will be maintained by the Federal Reserve Board. A stable interest rate outlook
combined with continued strength in consumer demand, should provide a favorable
environment for the stock and bond markets.

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS
With U.S. gross domestic product increasing more than investors anticipated in
the first half of 1998, the stock market enjoyed robust returns. Low interest
rates, benign inflation, low unemployment, and a rallying bond market all
contributed to positive investor psychology during the reporting period.
 
A number of factors combined to focus investor attention on large-capitalization
growth stocks. Continuing difficulties in Asian markets spread to China, Latin
America, and Russia, causing a flight to quality which attracted investors to
domestic companies and highly liquid securities. Asian difficulties also caused
problems for several technology companies. Declining oil, gold, and copper
prices caused weakness among energy and commodity-related issues and moved many
investors from undervalued securities into large, dependable growth companies.
 
Strong merger and acquisition activity stimulated interest in the stock market,
with several large deals in the financial sector. Problems with an earlier
merger, however, had a negative impact on Cendant, which was among the worst
performing stocks in the S&P 500 during the second quarter of 1998.
 
WHY WAS THE PORTFOLIO ABLE TO OUTPERFORM ITS PEERS?
The Portfolio benefited from strong security selection, strategic sales, and
strong growth among many of its core holdings. The Portfolio's domestic retail
holdings provided excellent performance. We reduced the Portfolio's technology
holdings, particularly among commodity-type products. At the same time, the
Portfolio benefited from strength in companies with proprietary products, such
as Microsoft and certain pharmaceuticals. Also, our decision to reduce holdings
in the oil services sector helped us reduce the impact of declining oil prices
on the Portfolio.
 
WHAT WERE SOME OF THE PORTFOLIO'S SIGNIFICANT PURCHASES DURING THE REPORTING
PERIOD?
The Portfolio purchased EMC, a corporate data storage provider with a consistent
growth record. The Portfolio sold some 3Com stock to make the purchase, a result
of our decision to reduce commodity-based technology companies and increase the
Portfolio's exposure to companies which offer more proprietary products and
services. EMC rose 63% in the first half of 1998 and had a positive impact on
the Portfolio's performance.
 
The Portfolio also purchased Pfizer, which had a slightly negative impact on
performance as some investors sold their positions in order to take profits in
the stock. Nevertheless, we believe that their accelerated earnings growth,
broad product line, and direct-to-the-consumer marketing strategy may result in
strong performance over the next six to twelve months.
 
Another large purchase for the Portfolio was Disney, which we quickly sold when
the stock began to decline, with a slightly negative impact on performance. A
more positive holding was Colgate-Palmolive, which the Portfolio bought in late
April. The company is benefiting from its global scope, cost cutting, and track
record of generating dependable earnings. With the recent sales success of the
company's toothpaste called Total, we believe it will have excellent potential
going forward.
 
                                        9
<PAGE>   10
 
WERE THERE ANY SIGNIFICANT SALES DURING THE REPORTING PERIOD?
The Portfolio sold Adaptec, which had a dramatically negative change in
fundamentals, due to Asian difficulties and a slowdown in earnings. The stock
declined 40% during the first half of 1998. The Portfolio also sold 3Com, which
we mentioned earlier, because of Asian difficulties and the company's inventory
problems in their U.S. robotics unit, which we expect to have a negative impact
on earnings.
 
As interest rates declined, mortgage refinancing activity increased, which had a
negative impact on mortgage insurer, MGIC Investment. With a declining growth
profile, we decided to sell the Portfolio's position late in the second quarter
of 1998 to take profits earned over the last several years. The Portfolio also
took profits in Mattel, a stock it has owned and sold over the years. We saw the
fundamentals weakening when sales of their Barbie Doll declined, Toys "R" Us cut
back on its inventory, and the company's Tyco toy division provided lower than
anticipated earnings estimates. The sale had a positive impact on the
Portfolio's performance.
 
DID YOU SAY YOU REDUCED HOLDINGS IN THE ENERGY SERVICES SECTOR?
Yes. We decided that with declining oil prices and reduced demand from Asia, we
would sell the Portfolio's position in Diamond Offshore Drilling and ENSCO
International. The Portfolio continued to hold Halliburton, which is an
exploration and drilling company, but we reviewed its prospects during the
reporting period. The general effect of holding energy services companies was
negative, so we viewed the sales as positive for the Portfolio.
 
WHICH STOCKS WERE THE BEST PERFORMERS?
Lucent Technologies was up 108.6% in the first half and had a substantial
positive impact on the Portfolio's performance, as it won telecommunications
contracts and continued to have solid earnings per share growth and an
attractive cost structure.
 
Tyco International is a conglomerate with holdings in fire retardation, security
systems, fiber optic cable, and health care. Tyco bought ADT Limited
International and Sherwood Davis, a medical device manufacturer, and advanced
nearly 40%, with a large and positive impact on the Portfolio's performance.
 
Schering-Plough is a premier pharmaceutical company. Its Claritin product for
allergy sufferers was an excellent performer, with $1.7 billion in sales and
rapid sales and earnings growth. Once again, the Portfolio benefited strongly as
the stock rose 48.3%.
 
WERE THERE OTHER STOCKS THAT PERFORMED WELL FOR THE PORTFOLIO?
Yes, there were several. Kohl's is a family apparel retailer that benefited from
many investors focusing on purely domestic names. The stock was up 52% with a
substantial positive impact on the Portfolio. Staples and Home Depot were other
retailers that fit a similar profile and also had a positive impact on
performance.
 
In the financial sector, the Portfolio had good success with SunAmerica, a major
annuity provider. The company markets fixed and variable annuities to a variety
of distribution channels including banks and stockbrokers. SunAmerica's
purchases of fixed and variable annuities have helped contribute to SunAmerica's
earnings per share growth in the 18% to 20% range during the reporting period.
Although the company had faced some questions last year about accounting
practices, it rose 35% during the reporting period.
 
Finally, in the communications area, the first quarter announcement that
WorldCom would purchase MCI, a telecommunications, long-distance, local, and
internet provider, caused WorldCom to rise 60% during the first half of the
year.
 
WERE THERE NAMES THAT DETRACTED FROM THE PORTFOLIO'S PERFORMANCE?
Cendant was a stock the Portfolio owned that had major problems in April. The
company was formed in the fourth quarter of 1997 from the merger of HFS and CUC
International. When certain of CUC's accounting practices came into question in
April, the stock price was cut in half. We believe the business units have
robust trends and are in vibrant sectors such as housing and travel, so as of
the end of June, the Portfolio continued to hold the stock. But the overall
impact of the news was negative for the Portfolio's performance.
 
WHAT DO YOU BELIEVE WERE THE BEST DECISIONS YOU MADE FOR THE PORTFOLIO DURING
THE FIRST HALF OF 1998?
Sticking to our investment disciplines and proactively reviewing every stock in
the portfolio. We decided to increase the Portfolio's weighting in the
securities we felt most confident about, within our diversification guidelines.
That led us to increase the Portfolio's holdings in companies like Lucent
Technologies, which were strongly positive.
 
                                       10
<PAGE>   11
 
We also believe our decision to reduce technology and energy stocks helped the
Portfolio, and sticking with the Portfolio's heavy exposure to domestic
retailers and financial firms helped performance in a low-interest rate
environment that stimulated consumer spending and loan activity.
 
WERE THERE ANY DECISIONS YOU MADE THAT YOU NOW REGRET?
Of course, in hindsight, we wish we hadn't held the Portfolio's position in
Cendant in April, but we could never have foreseen the difficulties the company
faced. We would have liked to have had zero energy exposure in the Portfolio,
but we're glad we sold the names we did.
 
WHICH SECTORS DID THE PORTFOLIO EMPHASIZE DURING THE FIRST HALF OF THE YEAR?
We're bottom-up investors that select stocks on their individual merits. As a
result of this approach, the Portfolio was overweighted in communications.
Although this sector underperformed as a whole, the Portfolio's communication
holdings returned more than 60% in the first half of the year. We were also
heavy in consumer cyclicals, such as retailers and restaurants, automotive
stocks, and housing, which were generally positive for the Portfolio's
performance, with the exception of Cendant.
 
Being overweighted in technology stocks was beneficial, primarily because we
chose companies with proprietary products for the Portfolio. Over the reporting
period, we decreased the Portfolio's exposure in light of the impact the Asian
difficulties had on technology production and the declining interest in
commodity-type products such as memory chips and adapter cards.
 
The Portfolio was also overweighted in financial stocks, although the companies
it held underperformed the market in general. Several were tied up in merger
transactions, and may perform well when the deals are completed.
 
WERE THERE SECTORS WHERE THE PORTFOLIO WAS UNDERWEIGHTED?
During the reporting period, the Portfolio was underweighted in basic materials
and capital goods, which was beneficial for performance. The Portfolio was also
underweighted in consumer staples, since many of the companies didn't meet our
growth criteria. While this sector underperformed in general, the Portfolio's
holdings outperformed the market.
 
Our decision to underweight in energy, utilities, and transportation stocks
generally had a positive impact on the Portfolio's performance.
 
WHAT IS YOUR OUTLOOK FOR THE FUTURE?
We believe the domestic economy is slowing down and may continue to do so as we
begin to feel the full impact of the Asian difficulties. That could result in
lower corporate profits, which may have a generally positive effect on companies
with dependable earnings growth, such as proprietary technology companies,
pharmaceuticals, retailers, and financial firms. Of course, it could also have a
negative effect if the impact of the Asian difficulties is severe.
 
We anticipate low inflation and possibly even lower interest rates. Whatever the
future brings, we will continue to apply our proprietary research disciplines as
the Portfolio seeks long-term growth of capital, with dividend income, if any,
as an incidental consideration.

MAINSTAY VP CASH MANAGEMENT PORTFOLIO
 
MARKET RECAP FOR THE SIX MONTH PERIOD ENDED 6/30/98

  first six months of 1998.
- - During the reporting period, the money market yield curve was flat and
  exhibited low volatility.
- - During the first half of the year, the average money market portfolio remained
  within a narrow range of 55 to 60 days to maturity.
- - Treasury bills were relatively expensive throughout most of the reporting
  period, moving opportunities into other segments of the money market.
 
PORTFOLIO RECAP FOR THE SIX MONTH PERIOD ENDED 6/30/98
- - The Portfolio stayed within 50 to 60 days to maturity throughout most of the
  first six months of 1998.
- - The Portfolio avoided Treasury securities in favor of commercial paper,
  floating-rate notes, certificates of deposit, Yankee obligations, and
  asset-backed securities.
- - The Portfolio owned only top-tier securities throughout the reporting period.
- - The Portfolio's 2.58% return outperformed the average Lipper(1) money market
  portfolio, which returned 2.54% for the six months ended 6/30/98.
 
PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS
During the first half of 1998, domestic bond and money markets were largely
influenced by world events. Economic contractions in Asian markets, including
Japan, caused difficulties in markets from Latin America to Russia and China.
One positive outcome has been relatively tame inflation, keeping the Federal
Reserve Board from adjusting domestic interest rates. As a result, interest
rates in general have remained within a relatively narrow range.
 
With a yield curve that was virtually flat, there were few advantages to
changing average maturity. The average money market portfolio stayed within a
range of 55 to 60 days to maturity throughout the first half of the year. With
the flight to quality surrounding the Asian difficulties and reduced federal
issuance, Treasury bills became somewhat expensive, shifting opportunities to
other market sectors.
 
WHAT ACCOUNTED FOR THE PORTFOLIO'S ABOVE-AVERAGE PERFORMANCE?
In an environment where the yield curve remains steady and relatively flat,
there was little opportunity to add value by extending maturities. We also
believed that Treasury bills were severely overpriced and avoided them in the
Portfolio. Instead, we looked for securities that offered yield advantages
without taking on substantial risk. We focused on domestic and Yankee financial
issues, corporate and asset-backed commercial paper, and floating rate notes.
Each of these sectors contributed to the Portfolio's above-average performance.
 
DID THE PORTFOLIO OWN ANY ASIAN SECURITIES?
No. We saw the problems in Asia and avoided their securities entirely. We did,
however, invest the Portfolio's assets in a number of international securities,
primarily Yankee issues of banks and insurance companies. In a low interest rate
environment, we felt financial firms would do well -- and their securities
showed strong performance throughout the reporting period. We selected credits
that were rated AA(2) or better, and the Portfolio remained focused on issuers
we felt had minimal Asian exposure.
 
DID THE PORTFOLIO FACE ANY CURRENCY RISK?
No. Yankee issues are denominated in dollars, so there's no currency risk.
 
ARE THERE ANY ADVANTAGES TO GLOBAL DIVERSIFICATION?
By diversifying with strong European issuers, we were able to expand the
Portfolio's horizons beyond domestic securities without increasing its risk. We
believe that diversification is an effective way of seeking to manage risk, so
we believe investors may benefit from global diversification, as long as the
quality remains high.
 
HOW MUCH DID THE PORTFOLIO INVEST IN COMMERCIAL PAPER?
A significant portion of the Portfolio's assets were invested in commercial
paper, including direct issues by corporations -- and asset-backed issues with
high credit quality, strong cash flows backed by collateral and highly rated
credit enhancement. Commercial paper contributed positively to the Portfolio's
performance.

<PAGE>   13
 
WERE THERE OTHER SECTORS IN WHICH THE PORTFOLIO INVESTED?
Yes, the Portfolio purchased some one-year floating rate notes that we believed
were inexpensively priced relative to commercial paper. The notes helped the
Portfolio's performance and gave us a good way to manage the Portfolio's average
maturity.
 
DID THE PORTFOLIO INVEST IN CALLABLE CDS OR OTHER ESOTERIC SECURITIES?
While the Portfolio has utilized those securities in the past, they offered few
advantages to issuers or investors during this relatively calm period in the
money markets. So the Portfolio invested primarily in simpler, "plain vanilla"
securities that offered greater liquidity. That decision was positive for the
Portfolio's overall performance.
 
HOW DO YOU SEEK TO MANAGE RISK IN THE MAINSTAY VP CASH MANAGEMENT PORTFOLIO?
One way is through careful credit analysis. In addition to seeing what the
rating agencies have to say, we watch the performance of corporate issuers in
the stock market. If their stock falters, we use it as a trigger to sell their
debt securities held in the Portfolio. We believe that the stock market can
discount new information much faster than rating agencies can reflect it.
 
The Portfolio also focuses on securities in the highest rating categories. The
Portfolio did not invest in second-tier issues and split-rated issues. In fact,
the lowest rating on any security the Portfolio owned was A-1/P-1(3) which is
very high. During the reporting period, the Portfolio only invested in top-tier
securities.
 
WHAT IS YOUR OUTLOOK GOING FORWARD?
Looking ahead, we believe that Asian turmoil, inflation expectations and
reactions to reduced Treasury financing have been almost fully priced into the
market. So we're taking a relatively neutral stand. While we remain bullish over
the long-term, we believe unusual movements in the yield curve and other minor
market fluctuations may present the most obvious opportunities in the next
couple of months. Whatever happens, we will continue to seek high-quality
securities that may provide a high level of current income consistent with
preservation of capital and liquidity.

MAINSTAY VP CONVERTIBLE PORTFOLIO
 
MARKET RECAP FOR THE SIX MONTH PERIOD ENDED 6/30/98
- - During the first half of 1998, domestic stocks and bonds both rallied, with
  the S&P 500(1) reaching record highs.
- - In general, convertible securities underperformed equities by a substantial
  margin.
- - Convertibles with exposure to Asian markets suffered as demand slackened
  throughout the Pacific region.
- - Difficulties among some major high yield issuers led convertible investors to
  reevaluate risks.
- - Telecommunications and media mergers pushed valuations to high levels, while
  declining oil prices resulted in losses among energy-related issues.
 
PORTFOLIO RECAP FOR THE SIX MONTH AND ONE YEAR PERIODS ENDED 6/30/98
- - The MainStay VP Convertible Portfolio returned 8.29% for the six month period
  ended 6/30/98 and 17.86% for the one year period ended 6/30/98.
- - Careful evaluation of risk and reward helped the Portfolio make sound
  investments in a market filled with individual disasters.
- - The Portfolio benefited from convertibles in a wide range of industries, while
  energy and commodity holdings underperformed.
- - The Portfolio underperformed the Lipper(2) Specialty/Miscellaneous Average,
  which returned 15.95% for the six months ended 6/30/98.
 
PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS
The first six months of 1998 provided positive stock market returns. Indeed, the
S&P 500 Index rose more than 17%, reaching record levels by the end of June.
Unfortunately, the convertible bond market didn't keep pace with the equity
market's advance. Problems among certain high yield issuers, notably Sunbeam,
Western Digital, FPA Medical, and Boston Chicken, caused investors to rethink
their risk parameters. Problems in Asian markets also took a toll, with
investors being forced to take losses even in highly liquid names.
 
As a result, the convertible landscape was strewn with individual disasters,
giving investors added incentive to carefully evaluate both the risk and reward
potential of the securities they selected. Merger and acquisition activity in
the telecommunications, cable and media industries pushed prices to high levels,
increasing the risk parameters of these convertibles, thus reducing the
opportunities in some of the largest sectors of the convertible market.
Declining oil prices caused energy-related issues to underperform and slipping
gold and silver prices caused precious-metal names to show poor performance.
Nevertheless, the market provided a wide range of opportunities among technology
companies, retailers, and other issuers with strong fundamentals and positive
earnings potential.
 
WHICH SECURITIES WERE THE WORST PERFORMERS DURING THE REPORTING PERIOD?
There were a few high yield issuers that faced serious problems. Sunbeam and FPA
Medical were large issuers whose fundamentals deteriorated. Fortunately, the
Portfolio didn't participate in either of those companies' offerings. Another
troublesome company was Boston Chicken, which the Portfolio held going into the
reporting period. Although we had hoped to see a turn in operations, the
management team failed to fix the company's problems and was eventually fired,
and the convertibles performed very poorly. Although it was the worst holding in
the Portfolio, the position was small and had a 40 basis point impact on overall
performance.
 
DO YOU CONTINUE TO HOLD BOSTON CHICKEN?
Yes. We believe that the market has overreacted to the company's problems and
anticipate receiving higher values if a restructuring plan is put in place.
 
WHICH SECURITIES DID THE PORTFOLIO PURCHASE DURING THE REPORTING PERIOD?
World Color Press was one of the Portfolio's biggest purchases and a strong
performer. We liked the company's management, the quality of its printing, and
its reputation in the industry. We had bought and sold the convertibles last
year in profitable transactions. When KKR, a major investor in World Color
Press, elected to sell a portion of its holding, it put pressure on the
convertibles and we were able to make significant purchases over the second
quarter of 1998 at attractive prices. The Portfolio purchased the bonds around
par value and at the end of the reporting period they were trading at a premium,
so they had a significant positive impact on the Portfolio's performance.
 
                                       14
<PAGE>   15
 
The Portfolio also bought 6.00% convertible bonds maturing in 2005 from Advanced
Micro Devices (AMD). AMD is the second largest chip manufacturer behind Intel
and had, we believe, an attractive offering in their K6 chip, the company's
answer to Intel's Pentium chip. Unfortunately, as demand in Asian markets
declined, the price of AMD stock went from the mid-20s into the teens. That took
a substantial toll on the Portfolio's performance. The Portfolio continues to
hold the convertibles because they offer a yield to maturity of over 9% and we
believe that they have good price appreciation potential.
 
DID THE PORTFOLIO HAVE OTHER MAJOR PURCHASES DURING THE FIRST HALF OF 1998?
As prices of Real Estate Investment Trust (REIT) securities declined through the
second quarter, we felt that they were an attractive investment for the
Portfolio based on both yield and valuation. In particular, we believed there
was fundamental value in the retail REIT sector, which was benefiting from
positive trends among major retailers.
 
In June, the Portfolio purchased a convertible preferred issued by General
Growth Properties, one of the largest owners of shopping malls in the United
States. The preferred issue offered a yield of 7.25%, and a very modest
conversion premium, thus allowing the Portfolio to participate in much of the
positive movement in the stock, with significant downside protection provided
through the yield.
 
CAN YOU GIVE AN EXAMPLE OF A SECURITY THAT WAS SOLD DURING THE REPORTING PERIOD?
Certainly. A company the Portfolio sold was Cendant, a company that resulted
from the merger of CUC International and HFS. We liked the mandatory convertible
preferreds when the Portfolio purchased them, but during the first half of the
year, questions about accounting irregularities at CUC International resulted in
both the stock and mandatory convertible preferreds being severely punished.
When the stock rebounded, the Portfolio sold the mandatory convertible
preferreds and moved into the convertible bonds, which should provide
significantly greater downside protection if the stock decreases from current
levels.
 
WHICH SECURITY PROVIDED THE BEST PERFORMANCE FOR THE PORTFOLIO DURING THE FIRST
HALF OF 1998?
The Portfolio did well with Time Warner convertible bonds and preferreds. In the
strong cable and media market, the stock did very well and the convertibles
followed suit. When they rose to the level where they took on the downside
characteristics of equities, we sold the Portfolio's position to reduce the
Portfolio's risk profile and take profits.
 
WERE THERE OTHER SUCCESS STORIES?
Yes. Newell Financial Trust convertibles moved from around 50 when the Portfolio
bought them last year to around 60 at the end of June 1998. So we pared back on
the Portfolio's position to take profits. Newell is a little-known integrator of
major brand names, from Rolodex and ball point pens to household products. Their
success has come from their ability to streamline manufacturing processes, and
their securities have been positive for the Portfolio.
 
WERE THERE PORTFOLIO HOLDINGS THAT DID POORLY DURING THE FIRST HALF OF THE YEAR?
Commodity prices, including precious metals, declined substantially during the
reporting period. The Portfolio held Coeur d'Alene Mines, a major name in silver
and gold mining that did poorly as precious metal prices declined.
 
IS THE PORTFOLIO OVERWEIGHTED OR UNDERWEIGHTED IN ANY SECTORS OF THE MARKET?
Generally speaking, we are bottom-up investors, which means we select securities
for the Portfolio based on their individual merits, rather than on sector
characteristics. Nevertheless, we believe that there is likely to be an upsurge
in real estate companies that service the retail sector. The Portfolio has taken
positions in a number of these real estate companies, and closed the first half
of 1998 overweighted in REIT securities. The Portfolio was also overweighted in
energy, and we believe that the larger energy companies may provide better
performance and more resilience to market forces.
 
The Portfolio ended the first half underweighted in media, which we believe is
overvalued. The Portfolio is also underweighted in steel, as metals and heavy
manufacturing have both shown weakness in recent months, particularly with the
General Motors strike situation.
 
WHAT IS YOUR OUTLOOK GOING FORWARD?
We continue to remain cautious about the potential for credit problems. Having
seen problems in several high yield issuers, we will continue to do careful
credit research before we invest. The disjointed, sector specific
 
                                       15
<PAGE>   16
 
behavior of the market may pose both opportunities and hazards going forward.
Going into the third quarter, we're beginning to find potential opportunities
among so-called busted converts, which trade like income securities because
their stock price has fallen significantly.
 
We will continue to focus on both the risk and reward characteristics of all the
securities we consider as we seek capital appreciation together with current
income.

MAINSTAY VP GOVERNMENT PORTFOLIO
 
MARKET RECAP FOR THE SIX MONTH PERIOD ENDED 6/30/98
- - Domestic bond markets were influenced by Asian economic contractions, a solid
  U.S. economy, and relatively tame inflation during the first six months of
  1998.
- - During the reporting period, the market experienced low volatility and a
  flattening yield curve in the second quarter.
- - Although 30-year Treasury bond yields declined to record levels in June,
  overall, yields tended to remain in a relatively narrow range.
- - Mortgage prepayments came in waves with minor shifts in interest rates over
  the reporting period.
 
PORTFOLIO RECAP FOR THE SIX MONTH AND ONE YEAR PERIODS ENDED 6/30/98
- - The MainStay VP Government Portfolio returned 4.15% for the six month period
  ended 6/30/98 and 11.22% for the one year period ended 6/30/98.
- - The Portfolio benefited by shifting from long to neutral duration in both the
  first and second quarters of 1998.
- - In the Treasury market, moving between newer and older issues provided
  opportunities to enhance returns.
- - Shifting the Portfolio's concentration in mortgage-backed securities also
  benefited the Portfolio, although being overweighted at the end of the second
  quarter had a negative impact on performance.
- - The Portfolio outperformed the average Lipper(1) general U.S. government
  portfolio, which returned 3.68% for the six months ended 6/30/98.
 
PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS
During the first half of 1998, the domestic bond markets were largely influenced
by world events. Economic contractions in Asian markets, including Japan, caused
difficulties in markets from Latin America to Russia and China. One positive
outcome has been relatively tame inflation, which has kept the Federal Reserve
Board from adjusting domestic interest rates. As a result, interest rates in
general have remained within a relatively narrow range, with 2-year Treasuries
declining just 16 basis points over the first half of the year, and 30-year
Treasuries remaining flat in the first quarter, but declining 30 basis points in
the second quarter of 1998.
 
The market has begun to see a reawakening of investors to the fixed-income
market. Broad market returns exceeded 10% over the past year, returns equity
market participants would have expected before the strong bull equity market of
the past three years. Given the past two of three quarters, bond returns were in
line or exceeded stock returns and investors have responded by increasing their
allocation back to bonds.
 
The price rally led to a flattening yield curve, which presented some
opportunities from a technically oriented viewpoint and supply dynamics,
creating trading opportunities among newer and older issues. Higher-coupon
mortgage-backed securities saw high prepayments early in the year, creating
buying opportunities. Overall, however, Treasuries tended to outperform other
sectors over the first half of the year.
 
WHAT ACCOUNTED FOR THE PORTFOLIO'S STRONG PERFORMANCE?
The Portfolio's duration strategy benefited performance throughout the reporting
period. Given our strategically bullish outlook, we kept the Portfolio's
duration in the neutral to long range. Over the reporting period, the Portfolio
was neutral as rates headed higher and longer as rates were declining.
 
Another factor that helped the Portfolio outperform its peers was the yield
curve. In the first quarter, the yield curve was unchanged, so the Portfolio had
no opportunity to add value there. But in the second quarter, the curve
flattened about 20 basis points. Because the Portfolio was very heavily
concentrated in the back end of the market, it was able to draw substantial
benefit from the rally in 30-year Treasury bonds, compared to portfolios with
investments more evenly spread across various maturities.
 
WERE THERE SPECIFIC STRATEGIES YOU USED TO ADD VALUE TO THE PORTFOLIO DURING THE
REPORTING PERIOD?
Yes. We added value to the Portfolio through specific security selection in the
Treasury market. Using a variety of technical indicators, we moved between newer
and older issues to take advantage of shifting supply dynamics. The result was
an incremental increase in return. Older Treasuries added value in the beginning
part of both the first and second quarters, newer securities in the latter part
of each quarter. Over the period, the strategy had a positive impact on the
Portfolio's performance.
 
                                       17
<PAGE>   18
 
WHAT HAPPENED IN THE MARKET FOR MORTGAGE-BACKED SECURITIES?
At the beginning of the year, the Portfolio was underweighted in higher-coupon
mortgage-backed securities. At the time, we anticipated a surge in prepayments
and believed that mortgage-related bonds would underperform. That's exactly what
happened and our decision to reduce exposure to high-coupon mortgage securities
had a positive impact on performance.
 
After the prepayments rose, we increased the Portfolio's exposure to mortgage
securities, feeling that at their adjusted price levels they had appreciation
potential. At that point, we focused primarily on commercial mortgages, for a
couple of reasons. First, new issuance was heavy, but demand was not, which
tended to force prices down to attractive levels. We also liked commercial
mortgages because we believed they carried less risk of prepayments if interest
rates continued to decline.
 
WHAT WAS THE IMPACT ON THE PORTFOLIO'S PERFORMANCE?
As the market began to rally in the second quarter of 1998, we pared back on the
Portfolio's positions to take profits. Naturally, that was positive for the
Portfolio's performance. But the Portfolio remained overweighted in
mortgage-backed securities in the latter part of the second quarter, which hurt
performance a bit when a second wave of prepayments began.
 
As it happens, the Portfolio had invested in coupons that were relatively
insensitive to prepayment risk, but as the mortgage market in general
underperformed, we believe we missed some of the opportunities that were
available in the Treasury market.
 
DID THE PORTFOLIO MAKE ANY DRAMATIC SHIFTS IN ITS SECTOR ALLOCATIONS DURING THE
REPORTING PERIOD?
Not really. Overall, the Portfolio decreased its weighting in mortgages from
14.1% of net assets at the beginning of the year to about 13.5% at the end of
the first half of 1998. The allocation to Treasuries and agencies was increased
slightly, and the Portfolio's weighting in variable rate notes increased.
 
HAS THE PORTFOLIO MAINTAINED ITS HIGH QUALITY RATING?
Yes, it has. The overall credit quality of the Portfolio's investment portfolio
is agency,(2) which is better than AAA.(3) As we seek opportunities for the
Portfolio, we try to keep the Portfolio in the highest-quality securities to
avoid exposing the Portfolio's shareholders to unnecessary credit risks. We're
pleased with the Portfolio's recent performance, because we believe it has
provided investors with higher-than-average returns with lower-than-average risk
in the government securities market.
 
WHAT IS YOUR OUTLOOK FOR THE FUTURE?
We believe that the major factors influencing our strategy over the past
year -- Asian turmoil, inflation expectations, and reactions to the reduced
Treasury financing -- have been almost fully priced into the market. While we
remain bullish on bonds for the longer term, as we start the third quarter, we
are taking a more neutral strategy for the Portfolio. We believe that the
changes in the Treasury's financing calendar, given the budget surplus, may
provide opportunities along the curve. We also see potential opportunities in
mortgages that have low probabilities of refinancing.
 
Whatever happens, we will continue to seek securities that offer a high level of
current income, consistent with safety of principal.

MAINSTAY VP HIGH YIELD CORPORATE BOND PORTFOLIO
 
MARKET RECAP FOR THE SIX MONTH PERIOD ENDED 6/30/98
- - A robust economy, with low interest rates, modest inflation, and low
  unemployment helped most bond markets provide strong performance in the first
  six months of 1998.
- - In June, the yields on 30-year Treasury bonds declined to all-time lows,
  moving prices higher for most income securities.
- - While yield spreads remained narrow through most of the reporting period,
  spreads widened in June, expanding the return potential of lower-rated bonds.
- - Telecommunications and media continued to account for a substantial percentage
  of new issuance in the high yield market.
- - Record inflows continued to strengthen the high yield market throughout the
  reporting period.
 
PORTFOLIO RECAP FOR THE SIX MONTH AND ONE YEAR PERIODS ENDED 6/30/98
- - The MainStay VP High Yield Corporate Bond Portfolio returned 5.48% for the six
  month period ended 6/30/98 and 11.53% for the one year period ended 6/30/98.
- - As of 6/30/98, the Portfolio was rated five stars overall by Morningstar,
  Inc.(1)
- - The Portfolio benefited from individual security selection in higher-quality
  high yield bonds and increased holdings among bonds rated B(2) as spreads
  widened in June.
- - The Portfolio benefited from being overweighted in industrials, media, from
  selected holdings in telecommunications and from being underweighted in
  cyclicals and commodity-related issues.
- - Looking ahead, the Portfolio has maintained its exposure to Asian markets and
  decreased its equity holdings.
- - The Portfolio outperformed the average Lipper(3) high current yield portfolio,
  which returned 4.58% for the six months ended 6/30/98.
 
PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS
During the first six months of 1998, the high yield bond market benefited from
the strength of the economy, benign inflation, and generally low interest rates.
Given the difficulties in Asia, it appeared unlikely that inflation would become
a problem, and the Federal Reserve Board did not move to affect interest rates.
Even so, in June, 30-year Treasury yields dropped to all-time lows, which helped
raise prices in most bond sectors.
 
Yield spreads, which were generally tight throughout the reporting period, began
to widen in the second quarter of 1998. This increased the return potential of
lower-rated securities, which had previously been low relative to inherent risk.
While default rates increased slightly during the reporting period, they
remained low relative to historical standards.
 
During the reporting period, new issuance remained strong among media and
telecommunications companies, but many of the securities appeared to be
overpriced. Asian difficulties led to widening spreads, creating opportunities
among issuers with strong fundamentals and adequate cash flow to service their
debt.
 
WHAT WAS THE PRIMARY REASON THE PORTFOLIO OUTPERFORMED ITS PEERS?
Strategic security selection. In evaluating high yield securities, we consider a
number of factors beyond just the yield. We consider the quality of the company,
its ability to cover its debt, and the amount of risk it might face in the event
of an economic downturn. During the reporting period, we were relatively
risk-averse for the Portfolio, stressing the upper quality tiers in the high
yield universe. As it happens, many of the securities we selected for the
Portfolio performed very well during the reporting period, particularly as the
markets reacted to Asian difficulties by preferring higher-quality issues.
 
The Portfolio also avoided much of the new issuance in the media and
telecommunications area, which we felt was overpriced. Instead, we concentrated
the Portfolio's telecommunications holdings in a few companies that we believed
had strong potential and outperformed the telecommunications sector as a whole.
 
DID THE PORTFOLIO OWN ANY TELECOMMUNICATIONS COMPANIES?
A good example of one would be CD Radio, a satellite company that proposes to do
for radio what Direct TV did for the television market. It plans to introduce
national satellite radio, which is an entirely new concept and one we believed
the market would find attractive. Since the company's bonds were the Portfolio's
top performers, our security selection proved beneficial for the Portfolio.
 
                                       19
<PAGE>   20
 
DID THE PORTFOLIO OWN OTHER SECURITIES THAT SHOWED STRONG PERFORMANCE DURING THE
FIRST HALF OF 1998?
Absolutely. The Portfolio benefited from Seven Sixty Seven Leasing paper, which
was a secured aircraft lease backed by 767s for TWA. The issuer bought back the
bonds from the Portfolio at a significant premium, which contributed positively
to performance.
 
During the reporting period, the Portfolio purchased bonds in UIH Australia
Pacific, which is a beneficiary of the consolidating Australian cable market,
and both securities contributed positively to performance. The Portfolio also
owned both stock and high yield bonds for Quest Diagnostics, a lab testing
company that we felt had outstanding potential and our judgment proved correct.
 
WHAT SECURITIES DID THE PORTFOLIO PURCHASE DURING THE REPORTING PERIOD?
The Portfolio purchased Octel Developments, a specialty chemicals company that
was spun off from Great Lakes Chemical. The company's bonds were attractive to
us, offering a combination of risk and reward -- characteristics we felt would
be positive going forward.
 
We were also attracted to Jafra Cosmetics International for the Portfolio, which
is a direct seller of cosmetic products in the United States, Mexico, and
Germany. The company is run by former senior managers from Mary Kay and Avon,
which we believe can help the company rapidly increase its market share.
 
The Portfolio purchased a convertible security from Cirrus Logic, a technology
company that makes chips and crystals and has very strong asset coverage. All of
these securities contributed positively to performance during the reporting
period.
 
DID THE PORTFOLIO PURCHASE ANY SECURITIES IN EMERGING MARKETS?
Yes. The Portfolio purchased bonds of Conproca and Hutchison Whampoa. Hutchison
Whampoa is a leading Hong Kong conglomerate with investments in
telecommunications, media, finance, and property. This investment is viewed as
particularly attractive given Hutchison's large U.S. cash position and the fact
that many of its assets are outside of Asia.
 
In late 1997, the Portfolio purchased another bond, issued by First Pacific
Capital, a successful Hong Kong conglomerate. During the first half of 1998, the
company completed an asset sale and showed strong bond performance as its debt
coverage increased. We increased the Portfolio's position in First Pacific
Capital during the reporting period, and the bonds have contributed positively
to performance.
 
WHICH SECURITIES DID THE PORTFOLIO SELL DURING THE REPORTING PERIOD?
The Portfolio had a number of successful sales during the first half of 1998.
The largest was Viacom, where we cut the Portfolio's position in half to take
profits. We bought and sold Columbia/HCA Healthcare during the reporting period,
which had a positive impact on performance.
 
In addition, we trimmed back on some of the Portfolio's higher quality holdings
as spreads began to widen and we believed there was greater opportunity in lower
quality securities.
 
CAN YOU EXPLAIN WHAT YOU MEAN BY A GREATER OPPORTUNITY IN LOWER QUALITY
SECURITIES?
Certainly. Last year, with relatively tight yield spreads between securities
rated BB(4) and B, we elected to invest the Portfolio primarily in the
higher-rated bonds, simply because we didn't feel that investors were being
adequately compensated for taking on additional risk. As yield spreads widened
during the reporting period, however, we decided that the compensation for
additional risk was in a more favorable range, and started to increase the
Portfolio's holdings in the single-B category.
 
WOULDN'T YOU HAVE BEEN BETTER OFF WITH SINGLE-B SECURITIES ALL ALONG?
During the reporting period, the yield advantage was only about 40 basis points.
But we look at more than just yield. We continue to believe that we're in the
late stages of a credit cycle and that high yield securities, by their very
nature, carry additional risks for which investors should receive adequate
compensation.
 
As it happens, even with the Portfolio's concentration in higher quality
securities, it was able to outperform the average Lipper high current yield
portfolio. In other words, the Portfolio was able to provide higher returns with
lower-than-average risk. We believe that's the kind of portfolio management
investors like to see.
 
DID THE PORTFOLIO'S SECTOR WEIGHTINGS HAVE A SIGNIFICANT IMPACT ON PERFORMANCE?
To answer that question, we need to point out that we're bottom-up investors,
evaluating securities one-by-one on their fundamental characteristics and
individual merits. Each of the Portfolio's sector weightings is a direct
 
                                       20
<PAGE>   21
 
result of this bottom-up investment process, which seeks to identify companies
with attractive returns, well-priced securities and a catalyst or stimulus for
improvement in the future.
 
With that in mind, the Portfolio did benefit from being overweighted in
industrials, media and emerging markets -- and from being underweighted in
telecommunications, where most securities were overpriced; commodities, where
prices were declining; and cyclicals, which were generally out of favor.
 
As we head into the second half of the year, we have reallocated the Portfolio's
assets, seeking to take advantage of strong asset coverage in the energy sector.
The Portfolio continues to be overweighted in media and emerging markets, and we
have strengthened the Portfolio's exposure in shipping.
 
WITH LOW OIL PRICES AND CONTINUING PROBLEMS IN ASIA, ISN'T THE PORTFOLIO TAKING
ON ADDITIONAL RISK?
Perhaps, but calculating the relationship between risk and reward is what high
yield investing is all about. We have already shown that selective
emerging-market investments can be beneficial, despite problems in Asia.
Although oil prices remain low and could even go lower, we believe the energy
companies in which the Portfolio is investing have more than adequate ability to
service their debt and we have purchased securities for the Portfolio at very
attractive prices.
 
Perhaps the biggest risk the Portfolio may face going forward is in being
underweighted in equities. If the stock market continues to climb, the Portfolio
could underperform its peers as a result. But we believe that the Portfolio is
well positioned given the company fundamentals, security prices, and inherent
risks in the market at the end of June.
 
WHAT IS YOUR OUTLOOK FOR THE FUTURE?
We believe the high yield market continues to offer opportunities and that
widening spreads may make lower-rated securities increasingly attractive. We
continue to be underweighted in telecommunications in the Portfolio because we
don't see attractive values there, and as long as steel and other commodities
demonstrate weakness, we're unlikely to move the Portfolio in that direction. We
continue to evaluate the relationship between risk and reward, both at home and
abroad, measuring asset coverage and free cash flow seeking to discover value
opportunities in the high yield bond market.
 
No matter how the markets may move, the Portfolio will continue to seek maximum
current income through investment in a diversified portfolio of high yield debt
securities.

MAINSTAY VP INTERNATIONAL EQUITY PORTFOLIO
 
MARKET RECAP FOR THE SIX MONTH PERIOD ENDED 6/30/98
- - International markets were divided in the first six months of 1998, with most
  Asian stock markets down and most European markets providing positive returns.
- - Australia and New Zealand stock performance deteriorated along with Asian
  markets, as problems intensified by declining prices in gold and other
  commodities.
- - In the United Kingdom (U.K.), the central bank increased interest rates to
  slow economic growth, which made it more difficult for Britain to compete in
  the export market.
- - Overall, the Morgan Stanley Capital International (MSCI) EAFE Index(1) was up
  15.93% for the six months ended June 30, 1998.
 
PORTFOLIO RECAP FOR THE SIX MONTH AND ONE YEAR PERIODS ENDED 6/30/98
- - The MainStay VP International Equity Portfolio returned 18.57% for the six
  month period ended 6/30/98 and 12.54% for the one year period ended 6/30/98.
- - The Portfolio outperformed the MSCI EAFE Index, which returned 15.93% during
  the six month reporting period.
- - The Portfolio benefited by shifting assets out of Asian markets and increasing
  its weightings in core European markets.
- - The Portfolio outperformed the average Lipper(2) international portfolio,
  which returned 16.25% for the six months ended 6/30/98.
 
PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS
International equity markets showed highly divergent performance during the
first six months of 1998, with Europe outperforming and Asian markets continuing
to deteriorate. Japan officially announced that it was in recession, and the
Hong Kong stock market fell 26% in local currency terms during the reporting
period. Asian emerging markets had even more severe setbacks. Australia and New
Zealand, whose economies are largely dependent on commodities and Asian
commerce, also fared poorly.
 
European stocks, on the other hand, surged ahead, with several markets posting
double digit returns in the first half of the year. Finland was up 66.8% and
Spain rose 44.5%, both in local terms, during the reporting period. Other
European markets also had excellent performance, buoyed by low interest rates,
low inflation, ongoing restructuring, and merger and acquisition activity
related to the European Monetary Union (EMU).
 
In an effort to slow rapid growth, the Bank of England raised interest rates,
which dampened the competitive environment for British exports and raised
concerns about U.K. equities. Although the U.K. will not be among the initial
participants in the EMU, in the future its stock market may move more
independently. Over the reporting period, the U.K. stock market advanced 14.1%
in local terms.
 
WHY WAS THE PORTFOLIO ABLE TO OUTPERFORM ITS PEERS?
The Portfolio came into 1998 well positioned for the market environment. Given
the continuing deterioration in Asian markets during the first six months of
1998, we decided to reduce the Portfolio's Asian exposure, which had a positive
impact on performance. The proceeds of those sales were invested primarily in
core European markets, which also had a positive effect. In this respect, our
investment approach of focusing on strict country selection served the Portfolio
very well. We also benefited from individual security selection within several
European markets and Japan.
 
WHICH COUNTRIES PROVIDED THE BEST RESULTS FOR THE PORTFOLIO?
In Europe, the best performing markets in which the Portfolio invested were
Spain -- up 44.5%, Belgium -- up 43.9%, France -- up 39.4%, Germany -- up 37.0%,
and Italy -- up 33.9%, all in local terms. Unfortunately, the Portfolio was not
invested in Finland, which was up 66.8% in local terms during the reporting
period. Finland's stock market performance was largely the result of a single
stock, Nokia, a telecommunications company. We felt that an overheating Finnish
economy and the rapid expansion of this single stock made Finland a high-risk
market. Concerned about its pace of economic growth, the Bank of Finland raised
interest rates to slow growth and control inflation.
 
                                       22
<PAGE>   23
 
WHICH MARKETS WERE THE WORST PERFORMERS DURING THE REPORTING PERIOD?
Fortunately, the Portfolio was not invested in the worst of the Asian markets.
We did, however, have substantial investments in Japan, which was up 4.0% in
local terms, but down 2.6% in U.S. dollar terms.
 
DID YOU CHANGE THE PORTFOLIO'S WEIGHTINGS SIGNIFICANTLY DURING THE FIRST SIX
MONTHS OF 1998?
Yes. We went from a neutral weighting in Europe to a heavily overweighted
position of about 82% of the Portfolio's total net assets. At the same time, we
substantially reduced Asian and Japanese holdings to just 8.5% of the
Portfolio's total net assets. In doing so, we sold 5.6% of the Portfolio's total
net assets, and raised German investments from 10.2% to 14.7% of the Portfolio's
total net assets. We increased the Portfolio's holdings in the Netherlands from
3.2% to 8.4% of total net assets. We also increased overall weightings in
Belgium and France.
 
HOW DID THE PORTFOLIO'S CURRENCY EXPOSURE AFFECT PERFORMANCE?
As the dollar rose relative to many foreign currencies, the Portfolio had
opportunities and disappointments. We took advantage of some volatile periods to
increase currency exposure in selected European markets, which had a modestly
positive impact on the Portfolio's performance. During the first six months of
1998, the Portfolio also had some exposure to the Japanese yen and Australian
dollar which had a negative impact on performance. Foreign exchange parity
levels have been established in Europe Monetary Union countries, and beginning
in 1999, exchange rates will play less of a role in investment decision making
in those nations.
 
WHICH SECURITIES IN THE PORTFOLIO WERE AMONG THE BEST PERFORMERS?
Olivetti Group is an Italian company that manufactures office and computer
equipment and provides telecommunications services in several countries. In the
second quarter of 1998, Olivetti Computers Worldwide, a subsidiary of Olivetti
Group, announced two powerful new servers, offering advantages over existing
corporate computer systems. The stock soared 195.2% in local terms over the
first half of the year.
 
Another stellar performer was KBC Bancassurance Holding, a Belgian financial
services holding company that moved to create a financial service giant,
including Kredietbank, Cera Bank, and ABB, an insurance group. In the first six
months of 1998, the stock rose 114.1% in local terms.
 
Mannesmann, an industrial products, machinery, and equipment manufacturer rose
104.1% in local terms after completing a $1.85 billion secondary offering to
expand its telecommunications operations in France and Italy. Another
multi-industry stock that was among the Portfolio's top performers included
Vodafone Group, up 71.5% in local terms. In addition, Telefonica and British
Telecom, telecommunications stocks, were up 67.7% and 54.6%, respectively, in
local terms.
 
WERE THERE OTHER OUTSTANDING PERFORMERS?
Yes. News Corp. is an international media company that grew 55.6% in local
terms, benefiting from existing operations and the formation of a multimedia
distributor in the United States.
 
Despite setbacks in Japan, the Portfolio benefited from individual stock
selection with Kawasaki Steel, up 40.4% in local terms, as a prime example.
 
DID ALL OF THE PORTFOLIO'S STOCKS DO THAT WELL?
No. Japanese retailer, Daiei, posted its first-ever pretax loss last year and
reversed its long-standing policy of not closing stores that generated losses.
The stock fell 39.8% in local terms during the reporting period. Nissan Motor
decided to reorganize and restructure to improve productivity and product
development. But in the meantime, the stock lost 19.1% in local terms. Tokyu,
Tokyo's leading railway company, felt the pressure of the nation's recession and
fell 16.5% in local terms, with the impact felt across all lines of business,
including real estate leasing and hotel operations.
 
WHAT PROMPTED YOU TO SELL SECURITIES IN THE PORTFOLIO?
As previously noted, we reduced the Portfolio's Asian exposure and increased its
European holdings to avoid problem areas and invest where we felt prospects for
growth were more attractive. We also reduced the Portfolio's holdings in
Australia as we saw the potential impact of declining gold and commodity prices.
Both of these moves were positive for the Portfolio's performance.
 
Although Spain was up 44.5% over the first six months of 1998, we decreased the
Portfolio's Spanish holdings to a minimal weighting in the second quarter to
take profits and invest assets where we believed they could do more good. Since
Spain only advanced 1.6% during the second quarter, this decision was also
positive for the Portfolio's performance.
 
                                       23
<PAGE>   24
 
WHAT IS YOUR OUTLOOK GOING FORWARD?
We continue to view Asia as a problem area, but even difficult markets can
provide opportunities for forward-thinking companies. The Japanese economy has
continued to disappoint us, but we believe that the strongest companies may be
the best performers there.
 
As EMU approaches, we remain relatively bullish on Europe, where we believe
restructurings, mergers, and strategic acquisitions will continue to abound. The
Portfolio will continue to seek long-term growth of capital commensurate with an
acceptable level of risk by investing in a wide array of non-U.S. equity
securities. As always, current income will remain a secondary objective.

MAINSTAY VP TOTAL RETURN PORTFOLIO
 
MARKET RECAP FOR THE SIX MONTH PERIOD ENDED 6/30/98
- - A robust economy, declining interest rates, modest inflation, and low
  unemployment moved both stocks and bonds higher in the first six months of
  1998.
- - Weaknesses in Asian economies caused a flight to quality bonds and highly
  liquid stocks that investors felt could perform relatively well in the event
  of an economic downturn.
- - Merger and acquisition activity was strong, helping the S&P 500(1) advance to
  record levels in June.
- - Although 30-year Treasury bond yields declined to record levels in June,
  overall, yields in all domestic bond sectors tended to remain in a relatively
  narrow range.
 
PORTFOLIO RECAP FOR THE SIX MONTH AND ONE YEAR PERIODS ENDED 6/30/98
- - The MainStay VP Total Return Portfolio returned 13.46% for the six month
  period ended 6/30/98 and 22.58% for the one year period ended 6/30/98.
- - The Portfolio benefited from individual security selection among financial and
  consumer retail stocks, and reduced its technology and energy holdings.
- - The Portfolio enhanced returns with a shifting duration strategy and strategic
  swaps in Treasuries, mortgage-backed securities and corporate bonds.
- - The Portfolio outperformed the average Lipper(2) balanced portfolio, which
  returned 9.61% for the six months ended 6/30/98.
 
PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS
With U.S. gross domestic product increasing more than anticipated in the first
half of 1998, the U.S. stock market enjoyed robust returns. Declining interest
rates, benign inflation, low unemployment, and a rallying bond market were among
the many factors that influenced investors during the reporting period.
 
A number of factors combined to focus investor attention on large-capitalization
growth stocks. Continuing difficulties in Asian markets spread to China, Latin
America, and Russia, causing a flight to quality in domestic issues and highly
liquid securities. Technology companies weakened on Asian setbacks, and
declining oil prices caused energy issues to underperform.
 
Asian problems helped keep the Federal Reserve Board from adjusting domestic
interest rates. As a result, interest rates in general have remained within a
relatively narrow range, with 2-year Treasuries declining just 16 basis points
over the first half of the year, and 30-year Treasuries remaining flat in the
first quarter, but declining 30 basis points in the second quarter of 1998. The
price rally led to a flattening yield curve, which presented some opportunities.
The budget surplus shifted supply dynamics among Treasuries. Mortgage-backed
securities saw high prepayments early in the year, creating buying
opportunities. Corporate bonds suffered from oversupply and widening yield
spreads, which made them an underperforming sector relative to the market as a
whole.
 
WHY WAS THE PORTFOLIO ABLE TO OUTPERFORM ITS PEERS?
The Portfolio benefited from strong security selection, strategic sales, and
strong performance among many of its core holdings in both the equity and income
components. As Asian difficulties continued, the Portfolio's domestic retail
stocks provided strong performance. We also reduced the Portfolio's technology
holdings and energy stocks, but bought stocks for the Portfolio or increased the
Portfolio's position among proprietary product providers. Reducing oil service
stock holdings helped us control the impact of lower oil prices on the
Portfolio's performance.
 
In the income component, the Portfolio benefited from its duration strategy,
moving from slightly long to neutral in both quarters, which had a positive
impact on performance. Among Treasuries, the Portfolio used a variety of
technical indicators for strategic trading between newer and older issues. In
the mortgage market, we successfully anticipated mortgage prepayments which
helped the Portfolio's performance. In the second quarter, the yield curve
flattened about 20 basis points. Our concentration in the back end of the market
allowed the Portfolio to benefit strongly from the rally in 30-year Treasury
bonds.
 
WHAT WERE SOME OF THE PORTFOLIO'S SIGNIFICANT STOCK PURCHASES DURING THE
REPORTING PERIOD?
The Portfolio bought EMC Corp. (EMC), a corporate data storage provider that has
had a consistent growth record, selling 3Com to make the purchase. The move
reduced technology holdings that concentrated on commodity-type products such as
memory chips and adapter cards and increased exposure to companies with
 
                                       25
<PAGE>   26
 
their own proprietary products and services. EMC rose 63% in the first half of
1998 and had a positive impact on performance.
 
The Portfolio also purchased Pfizer, which had a slightly negative impact on
performance as the company's shareholders took profits in the stock. We believe,
however, that the stock is well positioned for the coming months. The Portfolio
bought and sold Disney on changing fundamentals, with a slightly negative impact
on performance, and had positive results from Colgate-Palmolive, which is
benefiting from cost cutting, dependable earnings, and steady revenue growth
from its new toothpaste called Total.
 
WERE THERE ANY SIGNIFICANT SALES DURING THE REPORTING PERIOD?
The Portfolio sold Adaptec when its fundamentals deteriorated due to Asian
difficulties and a slowdown in earnings. The stock declined 40% during the first
half of 1998.
 
Declining interest rates had a negative impact on mortgage insurer, MGIC
Investment, and the Portfolio sold the stock late in the second quarter of 1998
to take profits earned over the years. The Portfolio also sold Mattel at a
profit, when Barbie sales declined, Toys "R" Us cut back its inventory, and Tyco
earnings estimates were disappointing. The sale had a positive impact on the
Portfolio's performance.
 
The Portfolio also sold Diamond Offshore Drilling and ENSCO International, two
oil service companies, as oil prices continued to decline. These stocks had a
negative impact on the Portfolio, so we viewed the sales as a positive move.
 
WHICH STOCKS WERE THE PORTFOLIO'S BEST PERFORMERS?
Lucent Technologies was up 108.6% in the first half of the year and had a
positive impact on the Portfolio's performance, as the company won
telecommunications contracts and built on its already strong fundamentals.
 
Tyco International is a conglomerate with holdings in fire retardation, security
systems, fiber optic cable, and health care. The company bought ADT Limited and
Sherwood Davis, a medical device manufacturer, and advanced nearly 40%, with a
positive impact on the Portfolio's performance.
 
Schering-Plough is a premier pharmaceutical company, which had outstanding sales
growth from Claritin, a product for allergy sufferers. The Portfolio benefited
as the stock rose 48.3% during the reporting period.
 
WERE THERE OTHER STOCKS THAT PERFORMED WELL FOR THE PORTFOLIO?
Yes. Several of the Portfolio's stocks benefited from investors' focus on purely
domestic retailers. Kohl's rose 52% during the reporting period, Staples was up
56%, and Home Depot rose 41%. In the financial sector, the Portfolio had
positive results with SunAmerica, a retirement annuity provider that rose 35%
during the reporting period. In the communications area, the first-quarter
announcement that WorldCom would purchase MCI -- a telecommunications,
long-distance, local, and Internet provider -- caused WorldCom stock to rise 60%
during the first half of the year.
 
WERE THERE NAMES THAT DETRACTED FROM THE PORTFOLIO'S PERFORMANCE?
Cendant was a stock the Portfolio owned that suffered a major setback when
accounting practices at one of its component companies came into question in
April. The stock price was cut in half and had a negative impact on performance.
We believe the business units have robust trends and are in vibrant sectors such
as housing and travel, so as of the end of June, the Portfolio continues to hold
the stock. We already mentioned Adaptec and MGIC Investment, which were negative
performers. Eli Lilly also underperformed expectations, when its osteoporosis
drug, Evista, failed to provide anticipated benefits for breast cancer patients.
 
WHAT WERE THE BEST DECISIONS MADE IN THE EQUITY PORTION OF THE PORTFOLIO DURING
THE FIRST HALF OF 1998?
The best decision made during the reporting period was sticking to our
disciplines and proactively reviewing every stock in the Portfolio's investment
portfolio. We decided to increase the Portfolio's weighting in the securities we
felt had the best potential -- companies like Lucent Technologies, which were
strongly positive.
 
We also believe our decision to reduce the Portfolio's technology and energy
stocks as well as overweight the Portfolio's exposure to domestic retailers and
financial stocks helped performance and positioned the Portfolio for the future.
 
WHICH SECTORS DID THE PORTFOLIO EMPHASIZE DURING THE FIRST HALF OF THE YEAR?
We're bottom-up investors and select stocks on their individual merits. As a
result of that approach, however, the Portfolio's equity component was
overweighted in communications, which underperformed as a sector, even
 
                                       26
<PAGE>   27
 
though the Portfolio's stock holdings were up significantly in the first half of
the year. The Portfolio was also heavy in consumer cyclicals, such as retailers
and housing, which were generally positive, with the exception of Cendant.
 
Being overweighted in technology stocks was beneficial, but mostly as a result
of our proprietary security selection, which emphasized companies with
proprietary product, for the Portfolio. Over the reporting period, we decreased
the Portfolio's technology exposure, by selling Adaptec, 3Com, and Compaq
Computer. The Portfolio was also overweighted in financial stocks, although the
companies held in the Portfolio underperformed the market in general. Several
were tied up in merger transactions, and may perform well when the deals are
completed.
 
WERE THERE SECTORS WHERE THE PORTFOLIO WAS UNDERWEIGHTED?
During the reporting period, the Portfolio was underweighted in basic materials
and capital goods, which was beneficial for performance. The Portfolio also was
underweighted in consumer staples, since many of the companies didn't meet our
growth criteria. While the group underperformed, the Portfolio's holdings
outperformed the market. Our decision to underweight energy, utilities, and
transportation stocks generally had a positive impact on performance.
 
WHAT ACCOUNTED FOR THE SOLID PERFORMANCE OF THE PORTFOLIO'S INCOME COMPONENT?
Our duration strategy benefited performance throughout the period. Given our
strategically bullish outlook, we kept the Portfolio's duration in the neutral
to long range. Over the period, we were neutral as rates headed higher and
longer as rates were declining.
 
WHAT OTHER STRATEGIES WERE USED IN THE PORTFOLIO'S INCOME COMPONENT?
With interest rates remaining in a relatively narrow range, we used a variety of
technical indicators to guide the Portfolio between newer and older issues in
the Treasury market. The result was an incremental increase in return. Older
Treasuries added value in the beginning part of both the first and second
quarters, newer securities in the latter part of each quarter. On the whole, the
strategy had a positive impact on the Portfolio's performance.
 
WHAT HAPPENED IN THE MARKET FOR MORTGAGE-BACKED SECURITIES?
At the beginning of the year, the Portfolio was underweighted in higher-coupon
mortgage-backed securities. Anticipating prepayments and believing that
mortgage-related bonds would underperform, we reduced the Portfolio's exposure
to high-coupon mortgage securities, which had a positive impact on performance.
 
After the prepayments rose, we increased the Portfolio's exposure to mortgage
securities in general, focusing primarily on commercial mortgages, for a couple
of reasons. First, new issuance was heavy, but demand was not, which tended to
force prices down to attractive levels. We also liked commercial mortgages
because we believed they carried less risk of prepayments if interest rates
continued to decline.
 
WHAT WAS THE IMPACT ON THE PORTFOLIO'S INVESTMENT PORTFOLIO?
As the market began to rally in the second quarter of 1998, we pared back on the
Portfolio's positions to take profits. But the Portfolio remained overweighted
in mortgage-backed securities in the latter part of the second quarter, which
hurt performance a bit when a second wave of prepayments began. Despite
selecting coupons that were relatively insensitive to prepayment risk, mortgages
in general underperformed.
 
HOW DID THE PORTFOLIO'S CORPORATE BONDS PERFORM?
As rates rallied at the beginning of the year, the prospect of low capital
attracted a number of corporations to the bond market. The oversupply of
corporates caused spreads to widen, causing the Portfolio's corporate bond
position to underperform in the first part of the first quarter. We increased
the Portfolio's exposure to strong, world-class companies whose bonds were
highly liquid, selecting companies like Coca-Cola Enterprises and Wal-Mart
Stores, which have strong domestic markets and do not depend on business in
Asia.
 
DID YOU CHANGE THE PORTFOLIO'S ASSET ALLOCATION MUCH DURING THE FIRST HALF OF
1998?
Not really. The Portfolio sold agencies at a profit and invested a bit more in
corporates and mortgage-backed securities. But overall, the allocation remained
relatively unchanged.
 
In addition to Treasuries and corporate bonds, the Portfolio continues to invest
in a wide range of mortgage-backed and asset-backed securities, including Ginnie
Maes, Fannie Maes, collateralized mortgage obligations,
 
                                       27
<PAGE>   28
 
low-balance loans, and manufactured-housing loans, and others. We believe that
this diversification may add value by reducing the risks associated with any
single sector of the market.
 
HAS THE PORTFOLIO MAINTAINED HIGH QUALITY INVESTMENTS THROUGHOUT THE REPORTING
PERIOD?
Yes, it has. The MainStay VP Total Return Portfolio's income component holds
securities that are generally of very high quality. As we seek opportunities for
the Portfolio, we try to remain in high-quality securities to avoid exposing the
Portfolio's shareholders to unnecessary risks. We're pleased with the
Portfolio's recent performance, because we believe it has provided investors
with higher-than-average returns with lower-than-average risk in the market.
 
WHAT IS YOUR OUTLOOK FOR THE FUTURE OF THE STOCK AND BOND MARKETS?
Looking ahead, we believe that Asian difficulties may have further impact on the
U.S. economy, which may create both challenges and opportunities. While we
anticipate low inflation and lower interest rates, we believe the wide gap
between stock prices and corporate profits and earnings may eventually cause
investors to rethink the types of stocks investors want to own. Meanwhile, we
will utilize our proprietary research and careful security selection process
seeking to identify opportunities for the Portfolio's shareholders. No matter
how the markets and the economy may move, the Portfolio will continue to seek to
realize current income consistent with reasonable opportunity for future growth
of capital and income.

  portfolio, which returned 12.26% for the six months ended 6/30/98.
 
PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS
With U.S. gross domestic product increasing more than investors anticipated in
the first half of 1998, the stock market enjoyed robust returns. Low interest
rates, benign inflation, low unemployment, and a rallying bond market all added
positively to investor psychology during the reporting period.
 
A number of factors combined to focus investor attention on large-capitalization
growth stocks and away from value issues. Continuing difficulties in Asian
markets spread to China, Latin America, and Russia, causing a flight to quality
which attracted investors to domestic names and highly liquid securities.
Declining oil, gold, and copper prices caused weakness among energy and
commodity-related issues, which are traditionally deep value sectors.
 
Financial stocks did well in a declining rate environment, with low inflation
keeping the Federal Reserve Board from taking any action. With strong consumer
confidence, higher employment and wage increases during the first half of the
year, retailers and selected automotive and auto-related stocks showed strength.
Transportation issues and tobacco stocks, on the other hand, showed relatively
weak performance. During the period, the top 30 stocks in the S&P 500 accounted
for half of the total return of the Index. This is an unusual concentration, the
magnitude of which was last seen in late 1972.
 
WHAT FACTORS CAUSED THE PORTFOLIO TO UNDERPERFORM ITS PEERS?
Value stocks in general were out of favor throughout the first half of 1998. Due
to our strict deep value investment disciplines, most of the best performing
stocks fell outside of our valuation tolerance.
 
The Portfolio did not compromise its value disciplines to seek higher returns in
a period when growth stocks were in favor. Instead, we utilized the weakness in
value stocks to reposition the Portfolio and seek issues at attractive
prices -- often in declining market sectors -- during the reporting period.
 
While the results were not always positive during the first six months of the
year, we believe we have positioned the Portfolio for stronger performance in
the future.
 
WHICH STOCKS DID THE PORTFOLIO PURCHASE DURING THE FIRST HALF OF THE YEAR?
The most significant allocation change in the Portfolio was in the energy
related sector, which represents about 8% of the S&P 500, but as of June 30
represented 13% of the Portfolio. In particular, we bought or added to our
positions in a number of exploration and production companies including Union
Pacific Resources Group, Oryx Energy, Apache Corp., Noble Affiliates and Texaco.
We found the stocks compelling on the basis of their price to cash flow
valuations. While these stocks were punished during the first six months because
of falling oil prices and reduced demand in Asia, we believe that if supply and
demand fundamentals improve, they may have strong potential going forward.
 
Late in the second quarter, cyclical stocks returned to our screens as strong
value candidates. Browning Ferris Industries is a waste management company we
found attractive, and purchased for the Portfolio during the
 
                                       29
<PAGE>   30
 
reporting period. We also found value for the Portfolio in Continental Airlines
and Northwest Airlines, which were trading at attractive prices because of
declining international and Asian air traffic.
 
Finally, Goodyear Tire & Rubber is a company that has gone through cost
restructuring and earnings development, but is still going through a period of
uncertainty related to economic difficulties in Asia and Brazil. We believe the
stock is undervalued and added it to the Portfolio.
 
WERE THERE OTHER MAJOR PURCHASES DURING THE REPORTING PERIOD?
Yes. We increased the Portfolio's tobacco holdings, largely because the
litigation controversy has depressed their prices well below the companies'
underlying asset values. Even taking the litigation risk into account, names
like RJR Nabisco Holdings and Philip Morris have been trading at values well
below the price of their assets, yet the stocks continue to provide yields that
are close to or above those available from Treasury securities.
 
We also added to the Portfolio's telecommunications holdings with US West. In
addition, we added to the Portfolio's utility holdings with Texas Utilities,
Illinova, OGE Energy, Niagara Mohawk Power and Energy East. Overall, utilities
were positive contributors to the Portfolio's performance, but as a group,
utilities underperformed the market.
 
WHAT POSITIONS DID THE PORTFOLIO SELL IN ORDER TO MAKE THESE PURCHASES?
In the utility area, the Portfolio redeployed capital from issues we felt had
reached their target valuations. The Portfolio sold PG&E and Long Island
Lighting, both of which outperformed the S&P 500 during the reporting period.
 
The Portfolio also sold a number of cyclical stocks in the first quarter of the
year, trimming back on paper and forest products companies that we thought might
underperform if Asian production slowed down. We sold Tenneco, Georgia-Pacific,
and Chesapeake to avoid short-term risk, even though we saw long-term merit in
the stocks. We may revisit these companies later in the year if valuations are
favorable.
 
We also had significant sales in the Portfolio's financial stocks, largely
because they rose so high they triggered our sell disciplines. The Portfolio
sold Bankers Trust New York and Chase Manhattan Bank, and substantially trimmed
its positions in Equitable, NationsBank, and Transamerica. All of these stocks
had a significantly positive impact on the Portfolio's performance.
 
WERE THERE OTHER SIGNIFICANT SALES DURING THE REPORTING PERIODS?
Yes. IBP is a meat packing company that didn't perform up to our expectations so
we sold some of the Portfolio's position. We also found that offshore drilling
companies were selling at a premium to exploration and production companies, so
the Portfolio sold Noble Affiliates in order to purchase the exploration and
production companies we mentioned a moment ago.
 
WHICH STOCKS WERE THE BEST PERFORMERS IN THE PORTFOLIO DURING THE FIRST HALF OF
1998?
 
About a third of the portfolio outperformed the market. Ford Motor was up 85% in
the first six months of 1998. Lexmark International Group, a printer company,
was up 60%. Equitable, which benefited from low interest rates, was up 50%, and
we pared back on the Portfolio's position to take some profits, while Xerox was
up 39%. And following the announcement of an acquisition by Dana Corporation,
Echlin, an automotive afterparts company, was up 38%. All of these stocks
reflected the potential in our value strategy, even in a market that showed a
strong preference for growth disciplines.
 
With low inflation and low interest rates, financial stocks did particularly
well, with NationsBank up 27%, CIGNA up 21%, and Bank One and Travelers Group
both up 15% for the reporting period. The strength of the economy, increasing
consumer confidence, and rising personal income also rewarded retail companies
like Federated Department Stores, which was up 25% for the first half of 1998.
The optimistic outlook also helped the gaming industry, sending Harrah's
Entertainment up 23% for the reporting period.
 
WHICH STOCKS UNDERPERFORMED?
As noted, the tobacco industry has been hard hit by sensational news reports
about ongoing litigation. RJR Nabisco Holdings was down 34% over the first six
months and Philip Morris declined 11%. However, their strong fundamentals and
attractive prices were consistent with our value discipline and we added to the
Portfolio's positions.
 
                                       30
<PAGE>   31
 
With declining oil prices, Union Pacific Resources Group dropped 27%, Seagull
Energy fell 20%, Oryx Energy declined 13%, and Apache Oil was down 10%.
 
During the reporting period, CSX, a railroad company, declined 15%, and
Northwest Airlines suffered from low Asian air traffic and lost 20% in the first
half of the year.
 
WHAT DO YOU FEEL WERE THE BEST DECISIONS YOU MADE FOR THE PORTFOLIO DURING THE
REPORTING PERIOD?
Our best decision for the Portfolio was to not allow any style drift during the
first half of 1998. We stuck to our value disciplines, and invested the
Portfolio's assets where we found value. In a period when growth stocks are
popular, it's tempting to go for their strong returns. It's tough to stick to
your discipline. But going against the grain when the market is rising may
position the Portfolio very favorably when market conditions change. We also
exercised good judgment in cutting back on companies with Asian exposure.
 
IN WHICH SECTORS IS THE PORTFOLIO CURRENTLY OVERWEIGHTED?
At the end of the first half of the year, the Portfolio was heavily overweighted
in materials processing, energy, transportation, and utilities, relative to the
S&P 500. In other areas, the Portfolio was generally in line with the Index.
 
WHAT IS YOUR OUTLOOK GOING FORWARD?
We believe that value stocks are at historically low valuation levels. With the
stock market selling at all time highs and a segment of the market --"deep
value"-- selling at a deep discount, we believe the time is right to take a
contrarian view and buy into a well-proven and low-risk value investment
approach.
 
The Portfolio will continue to seek maximum long-term total return from a
combination of capital growth and income, with a focus squarely on stocks that
we believe the market has undervalued.

MAINSTAY VP BOND PORTFOLIO
 
MARKET HIGHLIGHTS FOR THE SIX MONTH PERIOD ENDED 6/30/98
- - Global concerns continued to be a dominant influence in the fixed income
  markets.
- - The flight to quality trade contributed to the market's rally during the first
  half of 1998. The 30-year U.S. Treasury bond yield declined 29 basis points
  during the period.
- - The low interest rate environment contributed to prepayment concerns in the
  mortgage-backed security sector and significant corporate bond issuance. These
  factors caused spread product to widen during the first six months of 1998.
- - The Federal Reserve Board (the "Fed") maintained a stable monetary policy for
  the first half of 1998.
 
PORTFOLIO HIGHLIGHTS FOR THE SIX MONTH PERIOD ENDED 6/30/98
- - For the six months ended June 30, 1998, the MainStay VP Bond Portfolio
  returned 4.35%.
- - The Portfolio outperformed the average A rated corporate bond fund in its
  Lipper(1) universe by 38 basis points.
- - The Portfolio ranked fourth out of 33 bond funds (top 12.1%) for its Lipper
  category.
- - An average portfolio quality of at least AA- was maintained throughout the
  first half of 1998, limiting credit risk.
 
PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS
 
The year began amid investor concern regarding the Asian crisis and its impact
on the domestic economy. Market sentiment seemed to point toward a neutral to
accommodating Fed, along with declining corporate earnings. As the first quarter
progressed, it became apparent that an Asian induced slowdown would not have its
anticipated near-term effect on the U.S. economy. Statistical reports continued
to show resilient economic growth. The decline in oil prices along with
continued benign inflation numbers allowed the market to rally slightly in the
first quarter. The market continued to rally in the second quarter as
participants renewed their focus on the improving Federal Budget and its impact
on the supply of U.S. Treasury bonds. As the second quarter progressed, fears
about Asia re-emerged with a focus on Japan. These concerns refueled the flight
to quality trade.
 
TO WHAT DO YOU ATTRIBUTE THE PORTFOLIO'S POSITIVE PERFORMANCE?
 
The Portfolio limited its exposure to long duration spread assets. These longer
duration assets were the most adversely effected by spread widening in the first
half of 1998. The Portfolio also had a concentration in lower quality investment
grade corporate bonds in the one to five year maturity range. This asset
allocation worked well as these securities outperformed in their sector.
Additionally, our high quality assets benefited from the flight to quality
trade.
 
WHAT WAS YOUR PRIMARY STRATEGY IN THE FIRST HALF OF 1998?
 
The Portfolio shifted assets from the corporate and mortgage sectors to the U.S.
Treasury sector. We took these actions to take advantage of the flight to
quality trade and to reduce the Portfolio's credit and call risk.
 
WHERE DO YOUR PERCEIVE RISK IN THE PORTFOLIO?
 
The Portfolio's current mortgage-backed security holdings could present
prepayment risk if interest rates continue to trend lower. However, this
prepayment risk is actively managed based on our prevailing interest rate
forecast. The Portfolio's overall credit quality and structure continues to be
consistent with our long-term conservative management approach.

<PAGE>   33
 
WHAT IS YOUR OUTLOOK FOR THE FIXED INCOME MARKET IN THE SECOND HALF OF 1998?
 
We expect continued weakness in the Asian markets and a rise in the dollar to
bring about a decline in U.S. exports and a rise in imports that could dampen
domestic growth over the rest of the year. We believe the Fed will retain its
wait and see attitude toward monetary policy until the full effects of the Asian
crisis unfold. We expect the market to retain its focus on the problems in
Japan. Therefore, we believe U.S. Treasury security price movements should
continue to react to the dollar/yen relationship.

MAINSTAY VP GROWTH EQUITY PORTFOLIO
 
MARKET HIGHLIGHTS FOR THE SIX MONTH PERIOD ENDED 6/30/98
- - Low inflation and interest rates have enabled the stock markets price/earnings
  valuation to expand.
- - Asia's problems have had a limited effect on U.S. corporate earnings.
- - Continued strong inflows into equities continue to boost liquidity and market
  performance.
- - Merger and acquisition activity is extremely robust and poised to surpass
  1997's record level by a wide margin.
 
PORTFOLIO HIGHLIGHTS FOR THE SIX MONTH PERIOD ENDED 6/30/98
- - For the six month period ended June 30, 1998, the Portfolio had a return of
  16.20%.
- - We increased the Portfolio's exposure in technology stocks which were our best
  performers in the first half of the year.
- - The Portfolio's consumer staples holdings, which we continue to overweight,
  registered above average gains in the first six months of the year.
- - The Portfolio is in line with the Lipper(1) growth fund average return of
  16.23%.
 
PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS
The U.S. equity market continued to register impressive gains for investors in
the first half of 1998. The majority of the market's gains can be attributed to
investors' increased comfort level with low inflation which has increased equity
valuations. Simply stated, with interest rates at their current low levels, the
attraction of equities remains favorable.
 
Another ingredient causing the equity markets to move higher has been based on
positive corporate earnings growth. Economic growth should remain positive as
the domestic economy remains strong despite Asia's woes weighing down some
cyclical industries. Actually some industries, such as retailing, are benefiting
from low cost goods from Asia.
 
The current market environment supports our view of investing primarily in
companies with consistent earnings growth profiles. We believe that companies
which report earnings in line with expectations will receive premium valuations
to the market. We are avoiding industries which are negatively affected by Asia,
as we believe that the economic contraction in that region of the world will
persist longer than the market is currently discounting.
 
DURING THE REPORTING PERIOD, WHAT WERE THE MOST SIGNIFICANT FACTORS THAT
INFLUENCED THE EQUITY MARKET?
The most significant factor influencing the equity market throughout the first
half of the year was the effect Asia's problems were having on our economy. Most
commodity and export related industries have been adversely affected by the
slackening demand out of Asia and the excess industrial capacity that has been
built up in that region of the world in the last few years. However, most
consumer companies prospered as the domestic economy boomed due to continued low
interest rates and strong wage growth. These factors combined to create an
extremely favorable environment for domestically oriented companies.
 
HOW WAS THE MAINSTAY VP GROWTH EQUITY PORTFOLIO AFFECTED BY THE SIGNIFICANT
FACTORS JUST MENTIONED? WHAT ACTIONS DID YOU TAKE AND WHAT WAS THE FINAL RESULT?
The MainStay VP Growth Equity Portfolio is currently structured with a growth
stock orientation due to our expectation for moderate overall growth in the
economy. We determined that the more cyclical sectors of the economy would
suffer depressed earnings growth as commodity prices remained under pressure.
Thus, the Portfolio has favored domestic issues with a consistent earnings
growth profile. The results were favorable as the MainStay VP Growth Equity
Portfolio generated a return of 16.20% for the six months ended June 30, 1998.
 
WHAT WERE THE MOST SIGNIFICANT PURCHASES DURING THE REPORTING PERIOD? WHY DID
YOU MAKE THEM? HOW DID THEY AFFECT THE PORTFOLIO'S PERFORMANCE?
Our best purchases in the first half of the year were Dell Computer (up 94%),
Lucent Technologies (up 78%), EMC (up 67%) and Network Associates (up 31%).
These companies are located in the technology sector and conduct the majority of
their business domestically. Lucent Technologies, EMC and Network Associates
each rely on proprietary products which give them an advantage over their
competition. Dell Computer which
 
                                       34
<PAGE>   35
 
operates in the highly competitive personal computer market has prospered due to
its low cost distribution model.
 
WERE THERE ANY SALES DURING THE REPORTING PERIOD? WHY DID YOU MAKE THEM? HOW DID
THE SALES AFFECT PORTFOLIO PERFORMANCE?
The Portfolio sold out of its lodging holdings (Marriott International and
Hilton Hotels) because we felt that this highly cyclical industry had approached
its peak earnings potential. When Computer Associates made a hostile bid for
Computer Sciences earlier in the year we disposed of both stocks. We did not
believe that a combination of these two companies would be beneficial to
shareholders. After we sold both stocks, the merger was dissolved and both
company's stock prices moved upward.
 
DURING THE REPORTING PERIOD, WHICH SECURITIES CONTRIBUTED MOST POSITIVELY TO THE
PORTFOLIO'S PERFORMANCE? WHAT WAS THEIR RETURN? WHY DID THEY DO SO WELL?
America Online was the Portfolio's best performer in the first half of the year
with a return of 132.3%. The company continued to exhibit strong revenue
generation and operating performance with its online services. In addition,
speculation that a large communication or media company would merge with America
Online caused the valuation of the stock to appreciate. Cisco Systems was also a
strong performer in the first half of the year with a return of 65.1%. Cisco
Systems is the premier company in the dynamic networking and telecommunications
equipment industries. We believe the company and the industry will continue to
benefit as the explosive growth of the internet creates strong demand for their
products. Worldcom had a return of 60.1% in the first half of the year as the
stock rebounded from a sell-off late last year after it announced a merger with
MCI. As the year progressed, the market began to more fully appreciate the
growth potential of the telecommunications giant.
 
DURING THE REPORTING PERIOD, WHICH SECURITIES IN THE PORTFOLIO WERE THE WORST
PERFORMERS? WHAT WAS THEIR RETURN? WHAT WERE THE REASONS FOR THEIR
UNDERPERFORMANCE? DO WE STILL OWN THE SECURITIES? WHY?
Our worst performing stocks in the first half of the year were Cendant (down
40%) and Sunbeam (down 74%). Cendant's problems were the result of some
accounting irregularities in one of the company's subsidiaries. We continue to
hold the stock because we believe that these problems were an isolated incident
and that the market overreacted to this situation. The company acted quickly to
reassure the investment community that the accounting problems were being
resolved and the overall growth prospects of the company remain strong. We are
closely monitoring the situation and will sell our holdings if the company
discloses any more irregularities. Sunbeam's problems were of a similar nature
as the company appears to have overstated earnings during the last few quarters.
We have sold that stock because we believe that the company has a long road to
travel as it repairs its image to both its customers and investors.
 
WHAT WERE THE BEST AND WORST DECISIONS YOU MADE FOR THE PORTFOLIO DURING THE
REPORTING PERIOD? WHY DID YOU MAKE THEM AND HOW DID THEY AFFECT THE PORTFOLIO?
The best decision the Portfolio made in the quarter was increasing our weighting
in technology stocks as this group was the best performing market sector in the
first half. In particular, our concentration in the software and services side
of technology was very important as they outperformed the more commodity
oriented companies. The worst decision the Portfolio made was not underweighting
our energy holdings to a greater extent. Unfortunately, we underestimated the
impact Asia was going to have on the overall demand for oil.
 
IN WHAT SECTORS WAS THE PORTFOLIO OVERWEIGHTED OR UNDERWEIGHTED DURING THE
PERIOD? WHY? HOW DID THIS AFFECT PERFORMANCE? HOW IS THE PORTFOLIO CURRENTLY
POSITIONED?
The Portfolio is currently overweighted in technology and consumer staples. Our
overweighting in technology is focused in the less cyclical software and
computer services sector which is benefiting from the increased spending by
corporations on year 2000 computer compliance. The Portfolio's technology
holdings outperformed the market by a wide margin in the first half of the year.
The Portfolio's consumer staples holdings exceeded the market due primarily to
our media holdings. The Portfolio is currently underweighted in basic materials,
energy and capital goods. Our underweighting of basic materials and energy was
timely as both sectors underperformed the market in the first half of the year.
 
                                       35
<PAGE>   36
 
WHAT IS YOUR OUTLOOK GOING FORWARD? WHAT SECURITIES/SECTORS ARE YOU FOCUSING ON?
Our outlook going forward could be best described as cautiously optimistic. With
inflation and interest rates remaining subdued and corporate earnings growth
continuing, we believe that the stock market can progress upward. Our main
concern is focused on corporate earnings, as Asia's woes will probably have a
longer tail duration than the market is currently discounting. Thus, we will
continue to position the Portfolio in domestically oriented companies in sectors
such as financials, consumer staples and technology.

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS
A number of factors clearly influenced stock market returns over the first half
of 1998. Primary among these was the persistence of strong economic growth and
low inflation in the United States. As of the last reading, GDP was increasing
at a rate in excess of 5% a year, well above what most economists consider
sustainable. At the same time, consumer confidence soared, capital expenditures
continued unabated, and unemployment fell to its lowest level in 20 years.
 
The typical reaction of the Federal Reserve to such rapid growth is to raise
short-term interest rates -- the rates at which corporations borrow money to
fund the growth of their business. In so doing, they hope to head off inflation
by slowing the economy before price pressure has an opportunity to mount. In
1998, however, there have been few signs of inflationary pressure. Consumer and
producer prices have remained in check, wage growth has been less than that of
the economy, and the price of raw materials has plummeted. Absent the threat of
inflation and concerned that a hike in rates might strengthen the dollar and
compound Asia's economic problems, the Federal Reserve Board has refrained from
raising rates.
 
The impact of the global economy on U.S. stock prices is less easily
discernible. Continental Europe has enjoyed double digit gains -- over 40% in
many cases, both in local currency and U.S. dollar terms. Asia on the other hand
has languished amid currency devaluations, economic turmoil, and political
upheaval. For those companies that export goods to the region, maintain
facilities there, or compete with Asia's now less expensive products, this is
certainly a negative development and will likely become more so in the second
half of 1998. But for manufacturers that import raw materials and for the
consumers of these goods, it has been a windfall.
 
The S&P 500 is a broad index, and its performance was affected by a variety of
other factors. In this overall market environment, however, the S&P 500 climbed
17.71% in the first six months of 1998, a rate well above historic norms for an
entire year.
 
WHAT WAS THE PRIMARY REASON WHY THE PORTFOLIO UNDERPERFORMED THE INDEX AND ITS
PEERS?
The Portfolio performed precisely as anticipated, closely mirroring the S&P 500
Index but trailing by a slight margin due to Portfolio expenses. The Index
itself is a hypothetical investment and does not face the day-to-day expenses
associated with Portfolio investing. In addition, the Portfolio cannot fully
replicate the Index at all times, since it must make ongoing accommodations for
new investments and withdrawals. With the Portfolio underperforming its average
peer portfolio by just 20 basis points, the impact of these factors was minor.

DURING THE REPORTING PERIOD, WHICH INDUSTRIES CONTRIBUTED MOST POSITIVELY TO THE
PORTFOLIO'S PERFORMANCE?
Makers of communications equipment (computer networking) posted the highest
industry-group return of 61.8%. With a growing domestic economy, high
employment, rising personal income, and strong consumer confidence, companies
producing goods and services also generated strong performance. Apparel
retailers were up 55.8%, with retail in general rising 50.7%, automobiles were
up 50.9%, personal loans rose 37.3%, and restaurants advanced 36.5%.
 
WHICH INDIVIDUAL HOLDINGS SHOWED THE STRONGEST PERFORMANCE?
Capital One Financial generated the single highest gain for the period of
129.2%. Other strong performers were Dell Computer, up 121.0%; Apple Computer,
up 118.6%; Lucent Technologies, up 108.3%; and Unisys, which rose 103.6% during
the first six months of 1998.
 
WHICH INDUSTRIES PROVIDED THE WORST PERFORMANCE DURING THE REPORTING PERIOD?
Oversupply problems and shrinking global demand proved costly for oil and gas
companies in the first half of 1998. Those specializing in drilling declined
35.6%, well equipment and services stocks dropped 11.7%, and exploration and
production companies fell 9.7%. At the same time, declining commodity prices
drove mining companies in the S&P metals group down 9.9%. Other industries also
had disappointing results. Tobacco lost 13.9%, specialty chemicals dropped
13.0%, and railroads were down 11.1%.
 
WHICH INDIVIDUAL HOLDINGS RECORDED MAJOR LOSSES IN THE FIRST HALF OF THE YEAR?
With a decline of 49.2%, National Semiconductor was the worst performing holding
in the Portfolio during the reporting period. Semiconductor manufacturers
suffered from declining demand and write-offs on Asian operations. IKON Office
Solutions fell 48.2% when it preannounced a quarterly earnings shortfall and
Cendant dropped 39.3% when accounting practices at its CUC International
subsidiary came into question. Rounding out the five worst-performing issues
were Rowan Companies, down 36.3%, and Helmerich and Payne, which lost 34.4% in
the first half of 1998.
 
WHAT IS YOUR OUTLOOK FOR THE SECOND HALF OF 1998 AND BEYOND?
Securities markets are inherently unpredictable, particularly in the short term.
But taking a longer-term perspective, the bull market we have enjoyed the last
fifteen years is without precedent. By most traditional yardsticks
(price-to-earnings, price to book, dividend yield, capitalization to GDP),
current stock valuations are extremely high in historical terms. It is therefore
unlikely that stock returns in the coming decade will bear much resemblance to
those investors have enjoyed in recent years.
 
The past six months have even provided some indications that the good times
could be coming to an end sooner than we might wish. The credit spread between
Treasury bonds and comparable duration investment-grade debt widened noticeably,
suggesting a flight to quality. Likewise, the pattern of large companies doing
well and small companies struggling reflects a focus on highly liquid stocks
that are easy to sell in the event of a downturn.
 
The Portfolio will seek to track the total return performance of the S&P 500,
with dividends reinvested, whether the market moves up or down.

AMERICAN CENTURY INCOME & GROWTH PORTFOLIO*
 
Please note that the American Century Income & Growth Portfolio commenced
operations on May 1, 1998. Thus, the assets were not invested for the full
quarter. When reading the following commentary, please remember that although
some of the market commentary refers to the second quarter, the portfolio
commentary refers to the second two months of the quarter.
 
DURING THE PERIOD WHICH YOU MANAGED THE PORTFOLIO, WHAT WERE THE MOST
SIGNIFICANT FACTORS THAT INFLUENCED THE SPECIFIC MARKET IN WHICH YOUR PORTFOLIO
OPERATED?
The second calendar quarter of 1998 was characterized by "choppy" activity as
investors searched for clues to the market's direction. Individual investors as
well as professional money managers did not want to be left underinvested if the
capital markets were going to continue the impressive strength shown in the
first three months of the year. On the other hand, many remained somewhat
cautious about effects of unknown magnitude that would undoubtedly be caused by
the economic slowdown in Asia.
 
In specific market segments, whether it was in the "growth" category or the
"value" category, investors showed a strong preference for the relative
liquidity of larger-cap issues. As year-over-year operating earnings declined to
mid-single digits, investors willingly paid a premium for large companies
exhibiting growth characteristics.
 
No less than eight major mergers or acquisitions were announced in the second
quarter of the year, each one seemingly attempting to outdo the previous one.
The second quarter began with the announcement that the financial powerhouses of
Travelers Group and Citicorp intended to merge. A week later, four more banking
giants were getting together in two separate mergers. The acquisitive
NationsBank would be merging with money center BankAmerica Corp. That same day,
Banc One announced its intent to merge with First National Bank of Chicago.
Large mergers were not the sole domain of the domestic financial services
industry, however. U.S. auto maker Chrysler announced its intent to merge with
German industrial giant Daimler-Benz.
 
The next month saw four more major consolidations: American Home Products and
Monsanto; Norwest and Wells Fargo Bank; Berkshire Hathaway acquiring General Re
for $22 billion in stock; and AT&T announced that it plans to buy TCI, the
nation's largest cable operator. The acquisition of General Re was interesting
in that Berkshire Chairman Warren Buffet, who had written earlier in the year in
his company's annual report that the current high levels of the U.S. equity
markets did not leave much "margin of safety", generally prefers to pay cash for
his investments. Some interpret his willingness to do a deal with a more
valuable currency reflects his belief that Berkshire stock was overvalued.
 
Another phenomenon impacting the domestic markets was the apparent disconnect
between the valuations being placed on internet-related companies and their
underlying franchise fundamentals. In the few weeks following separate
announcements by GE and Disney that they were increasing their investment in the
Internet-related companies, many other companies saw their share prices soar.
Companies such as Yahoo!, Lycos, and Excite saw their market capitalizations
balloon. At the end of the second quarter, cyberspace book retailer Amazon.com
had a market capitalization greater than that of Barnes & Noble.
 
Even in a less-than-healthy IPO market, institutional investors demonstrated
their tremendous appetite for internet-related stocks. The "price talk" (the
initial filing range at which underwriter Morgan Stanley Dean Witter officially
thought shares could be sold) for Broadcom was $10-$12. Strong institutional
demand forced the deal to price at $24. On its first day of trading, shares
traded as high as $70, before closing at $53 3/8.
 
In the domestic fixed-income markets, bonds benefited from a "flight to quality"
due to the continued Asian economic weakness and fears of a slowdown in domestic
corporate profits. Unique in the second quarter was the outperformance of the
safest bond funds. Mutual funds that invest in U.S. Treasuries outperformed
highly rated corporate bond funds, and both generally outperformed high-yield,
or "junk" bond funds.
 
As inflation remained low and the supply of Treasuries continued to shrink
because of the favorable federal budget outlook, combined with the weakness in
Asia, bond yields (which move in the opposite direction of price) fell to their
lowest levels in 30 years.
 
HOW WAS THE PORTFOLIO AFFECTED BY THE SIGNIFICANT FACTORS JUST MENTIONED? WHAT
ACTIONS DID YOU TAKE AND WHAT WAS THE FINAL RESULT?
The Portfolio benefited from large-cap stocks in the auto & auto parts, computer
software, pharmaceutical, and financial services industries.
 
Inception date for the American Century Income & Growth Portfolio was May 1,
1998. In the following two months the Portfolio was being funded and
constructed.

<PAGE>   40
 
WHAT WERE SOME OF THE SIGNIFICANT PURCHASES DURING THE REPORTING PERIOD? WHY DID
YOU MAKE THEM? HOW DID THEY AFFECT THE PORTFOLIO'S PERFORMANCE?
The entire Portfolio was being established during this time period. While
securities in a broad range of industries were being purchased, the largest
weightings were in banks, financial services, pharmaceuticals, and
telecommunications.
 
DURING THE PERIOD WHICH YOU MANAGED THE PORTFOLIO, WHICH SECURITIES CONTRIBUTED
MOST POSITIVELY TO THE PORTFOLIO'S PERFORMANCE? WHY DID THEY DO SO WELL?
In the two months ended June 30, 1998, the largest contributors to positive
performance were Microsoft and Ford. Microsoft benefited from a relatively
strong technology market, a favorable court ruling, and because it is also one
of the largest capitalization issues in the market, further benefited from the
continued strength of large-cap global consumer growth companies.
 
Ford appreciated because of reports of strong sales and their increased
valuation, which resulted from some highly visible mergers in the industry which
were announced during the second quarter.
 
DURING THE PERIOD WHICH YOU MANAGED THE PORTFOLIO, WHICH SECURITIES IN THE
PORTFOLIO WERE THE WORST PERFORMERS? WHAT WAS THEIR RETURN? WHAT WERE THE
REASONS FOR THEIR UNDERPERFORMANCE? DO WE STILL OWN THESE SECURITIES? WHY?
Schlumberger, a large energy services company, was down in the two months.
However, a relatively small position in the Portfolio detracted only a modest
amount from positive performance. Stocks in this industry continued to be weak
due to the softened demand for energy worldwide resulting from the economic
slowdown in Asia.
 
WHAT WERE THE PORTFOLIO'S SIGNIFICANT SECTOR OVERWEIGHTS AND UNDERWEIGHTS DURING
THE PERIOD? WHY? HOW DID THIS AFFECT PERFORMANCE? HOW IS THE PORTFOLIO CURRENTLY
POSITIONED?
Relative to the S&P 500(1), the Portfolio's benchmark, the Portfolio was
overweighted in the following industries: financial services, computer software,
electric utilities, and aerospace & defense. Except for the last group, all of
these groups contributed to positive performance during the period; aerospace &
defense stocks detracted only modestly from the performance.
 
The pharmaceutical and food & beverage industries represented relative
underweights during the period but still contributed to positive performance.
 
At the end of the second quarter of the year, the fund's heaviest industry
weightings were in financial services, pharmaceuticals, computer software, and
telecommunications.

DREYFUS LARGE COMPANY VALUE PORTFOLIO*
 
Please note that the Dreyfus Large Company Value Portfolio commenced operations
on May 1, 1998. Thus, the assets were not invested for the full reporting
period. When reading the following commentary, please remember that although
some of the market commentary refers to the second quarter, the portfolio
commentary refers to the second two months of the quarter.
 
DURING THE PERIOD WHICH YOU MANAGED THE PORTFOLIO, WHAT WERE THE MOST
SIGNIFICANT FACTORS THAT INFLUENCED THE SPECIFIC MARKET IN WHICH YOUR PORTFOLIO
OPERATED?
As the second quarter ended, the price of the Standard & Poor's 500 Index(1)
moved into record territory after having been in a volatile trading range for
much of the period. Money continued to be attracted to the U.S. equity market,
as domestic money flows into stocks remained strong and worries about Japanese
financial system reform continued to attract foreign capital. Assets appeared to
be largely allocated into the S&P 500 Index and to most of its major security
components where valuations again set new records, well above any historic
period by almost any financial measure, according to our calculations. The
so-called "mega caps", the very largest U.S. companies, continued to drive the
performance of the S&P 500 Index, reminiscent of the early 1970's "nifty-fifty"
stocks and oil stocks in the early 1980's. Both of these "must own" markets
ended suddenly with significant corrections in those overvalued securities. Many
market participants may conclude that the risk level of the S&P 500 Index and
its major security components is high, although positive price momentum in this
index and in most of these mega cap stocks continues.
 
HOW WAS THE PORTFOLIO AFFECTED BY THE SIGNIFICANT FACTORS JUST MENTIONED?
The Dreyfus Large Company Value Portfolio was funded with cash on May 1, 1998.
The Portfolio was about 85% invested in stocks on day 1 and substantially fully
invested on day 2. In the positive stock market environment we have today, being
fully and quickly invested is perhaps the most important factor for a portfolio
of stocks.
 
Value stocks underperformed dramatically during the second quarter. The
performance difference between value and growth was the widest in memory. Any
value manager who remained true to their discipline could not hope to match the
return of the S&P 500 Index during this period.
 
HOW DID YOU SELECT SECURITIES FOR THIS PORTFOLIO?
Our approach to the selection of securities starts with and ends with our
analysts who are an integral part of our investment team. Our Dreyfus analysts
contribute their proprietary forecasts to our computer models, their analysis
and opinions to our decision-making process, and their constant flow of
information to our on-going assessment of owned securities.
 
We screen the universe of all large company stocks by computer according to two
principal methods. The first computer screen determines value by calculating
each security's earning yield (our forecast for earnings divided by the current
security price) which, to justify purchase, must be greater than the risk-free
yield available on reasonably long term U.S. Treasury securities. Being paid
more than this risk-free rate for the risk inherent in equity investing is
central to our value discipline. The second computer screen looks at 19 other
factors that have historically influenced stock returns including various
growth, valuation and leverage measures. We input into this computer model the
current economic and stock market trends, and the computer calculates each
security's exposure to the current environment. The model is an idea generator,
and further fundamental analysis is conducted on each potential holding to
determine its suitability for the Portfolio. Our analysts kick the tires,
interviewing various levels of management, competitors, customers and suppliers.
 
Combining all of this data with our analysts' in-depth knowledge of the
individual companies, we then construct a portfolio of approximately 60
securities. We use similar disciplined criteria and several other factors to
determine when selling a security is in our shareholder's best interest.
 
WHAT WERE SOME OF THE MOST SIGNIFICANT SALES DURING THE PERIOD WHICH YOU MANAGED
THE PORTFOLIO? WHY DID YOU MAKE THEM? HOW DID THEY FALL OUT OF YOUR STYLE? HOW
DID THEY AFFECT THE PORTFOLIO'S PERFORMANCE?
Several securities were sold during the period when these triggered one of our
sell disciplines. Sales because of our 15% stop loss rule included IKON Office
Solutions, Georgia Pacific, Cooper Cameron, Gateway 2000, Union Pacific, and
Sealed Air. While under other circumstances we might have given some of these
securities more time to perform, the small size of these security positions
permitted quick and easy sales, generally at prices above those of today.
Additionally, several other securities were sold opportunistically when we
determined that a negative event was about to occur which we could easily avoid
due to the small size of these positions. No securities were sold for valuation
reasons during this brief period.
 
                                       41
<PAGE>   42
 
DURING THE PERIOD WHICH YOU MANAGED THE PORTFOLIO, WHICH SECURITIES CONTRIBUTED
MOST POSITIVELY TO THE PORTFOLIO'S PERFORMANCE? WHY DID THEY DO SO WELL?
The best performing securities during this initial period for the Portfolio
included Niagara Mohawk, Owens Illinois, Allergan, McDonald's, Federated
Department Stores and Intel. Each security had its own particular reason for
outperformance. Broadly speaking, low consensus expectations were surpassed by
either improving earnings or positive fundamental changes at these companies.
 
DURING THE PERIOD WHICH YOU MANAGED THE PORTFOLIO, WHICH SECURITIES IN THE
PORTFOLIO WERE THE WORST PERFORMERS? WHAT WERE THE REASONS FOR THEIR
UNDERPERFORMANCE? DOES THE PORTFOLIO STILL OWN THESE SECURITIES? WHY?
The poorest performing securities during this brief initial period for the
Portfolio included IKON Office Solutions, Georgia Pacific, Cooper Cameron and
Gateway 2000. Again, there were reasons specific to each security for its
underperformance. Broadly speaking, Asian economic woes continued to weight
either directly or indirectly on each of these investments. All of these
securities were sold.
 
WHAT WERE THE BEST AND WORST DECISIONS YOU MADE FOR THE PORTFOLIO DURING THE
PERIOD WHICH YOU MANAGED THE PORTFOLIO? WHY DID YOU MAKE THEM AND HOW DID THEY
AFFECT THE PORTFOLIO?
The best decision for the Portfolio was becoming fully invested in stocks as
quickly as possible given the continuing strength of today's bull market.
 
The worst decision was being underweighted in financial stocks versus value
stock benchmarks during this short period. Financial securities were by far the
best performing securities among value stocks during the second quarter.
Financial stocks are about 18% of the S&P 500 Index and about 35% of the
Wilshire Large Company Value Index(2). Currently, the Portfolio has about 16% of
its assets invested in financial stocks which is toward the lower end of our
strategic range, a decision based on the high historic valuation of these
securities and some concerns about upcoming second quarter earnings reports. We
are selectively looking for opportunities to increase the Portfolio's weight in
financial securities.
 
WHAT WERE THE PORTFOLIO'S SIGNIFICANT SECTOR OVERWEIGHTS AND UNDERWEIGHTS DURING
THE PERIOD WHICH YOU MANAGED THE PORTFOLIO? WHY? HOW DID THIS AFFECT
PERFORMANCE? HOW IS THE PORTFOLIO CURRENTLY POSITIONED?
Our current portfolio strategy is to be positioned within each economic sector
generally between the economic sector weights of the S&P 500 Index and the
Wilshire Large Company Value Index. For example, financial stocks are
approximately 18% and 35% of each of these indexes, respectively. The Portfolio
will, therefore, generally have between 18% and 35% of its total assets in
financial stocks. We believe that being positioned within each economic sector
between these two benchmarks better positions the Portfolio to outperform both
indexes over the long term. Economic sectors come in and out of favor in the
stock market, usually with unpredictable timing. We choose to limit the
decisions about which economic sectors to overweight or underweight, and simply
attempt to select the best securities within each economic sector at any given
point in time. In our opinion, it is a lower risk strategy that we believe over
time leads to more consistent and better investment returns.
 
WHAT IS YOUR OUTLOOK GOING FORWARD? WHAT SECURITIES/SECTORS ARE YOU FOCUSING ON?
While we are cautious about the Standard & Poor's 500 Index and its major
components members due to historically high levels of valuation, we remain
positive on financial assets in general. Money flows into equity investments
remain strong, and we expect this liquidity to continue for the foreseeable
future. We are devoted to seeking large company investment opportunities at
value price across the economic spectrum.

EAGLE ASSET MANAGEMENT GROWTH EQUITY PORTFOLIO*
 
Please note that the Eagle Asset Management Growth Equity Portfolio commenced
operations on May 1, 1998. Thus, the assets were not invested for the full
reporting period. When reading the following commentary, please remember that
although some of the market commentary refers to the second quarter, the
portfolio commentary refers to the second two months of the quarter.
 
DURING THE REPORTING PERIOD, WHAT WERE THE MOST SIGNIFICANT FACTORS THAT
INFLUENCED THE SPECIFIC MARKET IN WHICH YOUR PORTFOLIO OPERATED?
"Two steps forward and one step back" describes the U.S. markets for the past
three years. The second quarter of 1998 was no exception. As U.S. economic
growth slowed from 5.4% in the first quarter to 2.0% in the second, so did the
domestic stock market as measured by the S&P 500(1). The S&P, which was up 14.0%
in the first quarter, rose only 3.3% in the second. Large, domestic growth
stocks outperformed most other asset classes for many reasons including a rush
of foreign investors seeking refuge in high quality securities. Retail stocks,
in general, performed well for the quarter due to a strong domestic economy and
little Asia exposure. Broad technology was mixed for the quarter. There continue
to be many cyclical technology companies experiencing earnings problems due to
over capacity and weak demand from Asia. Large-capitalization drug companies
continue to do well as their earnings are accelerating from new products and
pricing improvements. For the quarter, the financial sector underperformed but
had a strong month in June. This underperformance is primarily attributed to
uncertainty regarding the direction of interest rates. Many investors were
expecting an interest rate increase to slow the economy. However, for the time
being the Asian problems have slowed the economy naturally, making a near-term
increase in rates unlikely.
 
HOW WAS THE PORTFOLIO AFFECTED BY THE SIGNIFICANT FACTORS JUST MENTIONED, WHAT
ACTIONS DID YOU TAKE AND WHAT WAS THE FINAL RESULT?
The second quarter was an excellent one for both absolute and relative
performance for the Portfolio. Similar to the fourth quarter of 1997, investor
preference continues to be large-cap, liquid growth stocks that can deliver
earnings growth. The inception date for the Portfolio was May 1, 1998. The
Portfolio was down 1.5% compared to the S&P 500, which was down 1.7% for the
month of May. In June, the Portfolio rose 8.5% and the S&P rose 4.1%. Since
inception, the total returns were 6.9% for the Portfolio and 2.3% for the S&P as
of June 30.
 
We manage the Portfolio in a "bottom-up" style, focusing on specific stocks
rather than the economy or market cycle. Thus, we do not adjust the Portfolio in
an attempt to time the market. We have developed a strict investment discipline
to find the highest quality growth stocks in the U.S. We consistently follow
this discipline no matter which industries or sectors appear to be coming into
or cycling out of favor. This quarter, our retail, technology and pharmaceutical
holdings helped relative performance. The financial stocks hurt performance.
 
The best performing sectors for the entire quarter included our investments in
retail, which were up an average of 21%, technology up an average of 19%, and
pharmaceuticals up an average of 14%.
 
Similar to the first quarter of 1998, the primary sector of underperformance was
financial services. For the entire quarter, this sector returned on average 7%.
Likewise, performance across this group was very inconsistent. For example,
American Express was up 24% while Fannie Mae was down 4%.
 
WHAT WERE SOME OF THE MOST SIGNIFICANT PURCHASES DURING THE PERIOD WHICH YOU
MANAGED THE PORTFOLIO?
Because this was the first quarter the Portfolio has been in operation, every
security we purchased was new for the Portfolio. We are focused on finding high
quality, stable growth stocks.
 
WHAT WERE SOME OF THE MOST SIGNIFICANT SALES DURING THE PERIOD WHICH YOU MANAGED
THE PORTFOLIO? WHY DID YOU MAKE THEM? HOW DID THEY FALL OUT OF OUR STYLE? HOW
DID THEY AFFECT THE PORTFOLIO'S PERFORMANCE?
Microsoft (MSFT) was trimmed. Although we still like the long-term growth
prospects, we are concerned with the near term issues related to the Department
of Justice investigation. We believe that the ultimate impact of this
investigation will have little impact on their earnings growth; however, it
presents uncertainty, which the market never likes. This hurt performance in a
relative way because the stock price has since risen due to the resolution of
some of the legal issues.
 
AES (AES) was sold. This independent power producer has been a great growth
stock. The company has a significant new project based in Pakistan, which is at
risk due to political instability. This sale did not significantly impact
performance. The stock dropped after we sold it, but it has recovered somewhat.
We felt that the assets were better invested elsewhere.

DURING THE PERIOD WHICH YOU MANAGED THE PORTFOLIO, WHICH SECURITIES CONTRIBUTED
MOST POSITIVELY TO THE PORTFOLIO'S PERFORMANCE? WHAT WAS THEIR RETURN? WHY DID
THEY DO SO WELL?
Stocks that performed particularly well included Cisco (+25%) and Dell (+10%)
for May and June. Both benefited from a surge in the technology sector as well
as individual boosts from strong earnings announcements for the first quarter.
 
DURING THE PERIOD WHICH YOU MANAGED THE PORTFOLIO, WHICH SECURITIES IN THE
PORTFOLIO WERE THE WORST PERFORMERS? WHAT WAS THEIR RETURN? WHAT WERE THE
REASONS FOR THEIR UNDERPERFORMANCE? DO WE STILL OWN THE SECURITIES? WHY?
Stocks that underperformed included Freddie Mac (0%) and Fannie Mae (-1%) for
May and June. Both Freddie Mac and Fannie Mae slightly underperformed due to
concerns about the direction of interest rates. They had flat returns as spreads
on mortgages and loans tightened due to a flattening of the yield curve and low
volatility in interest rates. We continue to believe that both are sound
long-term holdings and continue to meet our strict buy criteria.
 
WHAT WERE THE BEST AND WORST DECISIONS YOU MADE FOR THE PORTFOLIO DURING THE
PERIOD WHICH YOU MANAGED THE PORTFOLIO? WHY DID YOU MAKE THEM AND HOW DID THEY
AFFECT THE PORTFOLIO?
The best decision we made during the quarter was to get the Portfolio invested
quickly as the market for large cap growth stocks continued to rise. The worst
decision we made was trimming Microsoft; in hindsight, the stock rebounded after
a court ruling in June.
 
WHAT WERE THE PORTFOLIO'S SIGNIFICANT SECTOR OVERWEIGHTS AND UNDERWEIGHTS DURING
THE PERIOD? WHY? HOW DID THIS AFFECT PERFORMANCE? HOW IS THE PORTFOLIO CURRENTLY
POSITIONED?
The Portfolio was overweighted in the financial services, technology, health
care, retail and consumer staples sectors. All of the sectors outperformed the
index for June as growth stocks and growth industries outperformed. We were
underweighted in cyclical stocks like transportation, basic materials and
energy. This underweighting also helped performance as the market rewarded high
quality growth positions instead of undervalued cyclical stocks. The Portfolio
continues to be positioned in a very similar allocation.
 
WHAT IS YOUR OUTLOOK GOING FORWARD? WHAT SECURITIES/SECTORS ARE YOU FOCUSING ON?
Is big better? Based on earnings growth and first half of the year stock
performance, it is. During the first half of 1998 earnings for the largest 50
stocks in the S&P 500 increased 10% versus the bottom 450 which decreased 2%.
Stock performance followed earnings growth with the largest 50 stocks up an
average of 30% versus the bottom 450 up only 10%. We believe that in the current
market environment, size can make a difference. The largest companies have the
capital to make strategic acquisitions and the economies of scale to invest in
technology to gain market share. We see this trend continuing.
 
We also believe the economy is slowing and inflation is under control. In turn,
we believe interest rates will remain low and trend lower. This continues to be
a very hospitable environment for growth stocks. In a slowing economic
environment investors want to own companies that will grow earnings with
certainty.
 
We continue our 1998 theme, to own companies with "bullet-proof " earnings,
meaning companies that have a history of consistently meeting analysts'
estimates of their quarterly earnings. We are focused on finding and continuing
to hold the highest quality growth stocks available.

LORD ABBETT DEVELOPING GROWTH PORTFOLIO*
 
Please note that the Lord, Abbett Developing Growth Portfolio commenced
operations on May 1, 1998. Thus, the assets were not invested for the full
reporting period. When reading the following commentary, please remember that
although some of the market commentary refers to the second quarter, the
portfolio commentary refers to the second two months of the quarter.
 
Certain economic indications during the period bolstered our expectation for the
Portfolio's performance. For example, the low inflation, high levels of
employment and high degree of consumer confidence that prevailed throughout the
quarter provided the necessary backdrop for many retail companies to report
higher earnings. In addition, relative valuations for small-cap companies
support our belief that these stocks remain inexpensive compared with large-cap
stocks.
 
The conditions mentioned above provided the portfolio management team with the
opportunity to invest the money of this recently seeded Portfolio in companies
that are very strong fundamentally, have superior long-term operating potential,
and are very attractive from a valuation standpoint.
 
The most significant purchases during the reporting period were Plantronics,
Orbital Sciences, and Information Management Resources. We are interested in
these companies for their unique market positions and tremendous growth
potential.
 
This portfolio has been in existence for less than 2 months. The management team
has focused on making its initial investments. Purchases have been widely
diversified. There have been no sales during this time.
 
Lord, Abbett's outlook for the remainder of 1998 is for economic growth to slow
to 2%-2.5%, with inflation continuing to remain moderate. We are encouraged by
the belief that many of our holdings will continue to experience strong growth,
albeit in a slowing economy, due to the unique nature of the products and
services they provide. Furthermore, we believe that changes in the tax laws
lowering capital gains tax rates are favorable to the growth arena in general,
and to innovators in small-cap companies in particular. We continue to focus on
companies with high consistent growth rates, exciting future prospects and
undervalued businesses. We remain committed to helping you achieve your
financial goals.

                                    GLOSSARY
 
ASSET-BACKED SECURITIES:  Securities backed by loan paper, receivables, or an
anticipated income stream from the sale of merchandise or services. The
securities are generally originated by banks, credit card companies, or other
providers of credit and often "enhanced" by a bank letter of credit or by
insurance from an institution other than the issuer.
 
AVERAGE MATURITY:  Maturity is the termination date of an obligation or the
length of time an income security is required to pay interest. Average maturity
reflects the average of the maturities of all fixed-income securities in a
portfolio.
 
BACK END OF THE MARKET:  Bonds are issued in a variety of maturities from very
short to as long as 30 years or more. The back end of the market refers to bonds
with longer maturities, such as 30-year issues.
 
BASIS POINT:  One hundredth of one percent in the yield of an investment, i.e.,
100 basis points equals 1%.
 
BOTTOM-UP INVESTING:  Security selection based on the specific portfolio
fundamental merits of individual issues. The opposite of "top-down" investing,
which starts with general economic trends, compares market sectors, and uses
relative security values to narrow the range of issues to examine.
 
BULLISH/BEARISH:  A bull market occurs when security prices are rising; a bear
market occurs when security prices decline. A bullish attitude therefore
suggests a positive outlook, while a bearish attitude represents a negative view
of the market or the opportunities it may present.
 
CASH FLOW:  The amount of income or earnings available to cover outstanding
liabilities and other obligations, including debt service.
 
CONVERSION PREMIUM:  The amount by which the price of a convertible security
exceeds the market price of the underlying stock. If a stock is trading at $50
and the convertible bond at $45, the premium is $5. When the premium is high,
the bond trades like an income security; when it is low, it trades like a stock.
 
CREDIT SPREAD:  The yield differential between debt securities of issuers with
varying credit ratings. Credit spread refers to the extra yield investors demand
for holding investment grade corporate bonds rather than the debt of the United
States Treasury (considered to be free of default risk).
 
CYCLICALS (CYCLICAL STOCK):  A security or stock that tends to rise quickly with
economic upturns and fall quickly when the economy slows. Noncyclical
industries, such as food, insurance, and pharmaceuticals, are likely to have
more consistent performance regardless of economic changes.
 
DEFAULT:  Failure of a debtor to repay principal or interest on an obligation or
to meet some other provision of a debt instrument. If an issuer defaults,
bondholders may make claims against the assets of the issuer to recoup their
principal.
 
DEFENSIVE ISSUES:  Stocks chosen for their reliability of earnings, growth, and
positive performance.
 
DEVALUATION:  A lowering of the value of a country's currency relative to gold
and/or the currencies of other nations. Devaluation can also result from a rise
in the value of other currencies relative to the currency of a particular
country.
 
DURATION:  A measure of price sensitivity, which adjusts for the time value of
the payments investors will receive and which takes into account interest
payments as well as principal payments. Duration is a better gauge of
interest-rate sensitivity than average maturity alone.
 
EARNINGS PER SHARE:  The portion of a company's profit allocated to each share
of outstanding common stock.
 
EMERGING MARKETS:  Countries with smaller or more recently established capital
markets.
 
EUROPEAN MONETARY UNION:  A proposed system that would allow participating
European countries to operate with a common currency or monetary unit.
 
FLIGHT TO QUALITY:  When investors in general move to improve the quality or
liquidity of the securities they own, because of economic, industry, market or
credit concerns that suggest lower quality securities or those that are less
liquid are likely to be more vulnerable to negative market events.
 
GROSS DOMESTIC PRODUCT (GDP):  The total value of goods and services produced in
the U.S. economy over a particular period of time, usually one year. The GDP
growth rate measures strictly domestic output and is a primary indicator of the
status of the economy.

GROWTH VERSUS VALUE:  Growth investments typically include stocks with rising
prices and positive earnings trends. Value investments typically include
equities that are currently trading below their fair market value, even if they
have the potential to increase in value over time.
 
INFLATION:  An increase in the cost of goods and services over time. As prices
rise, the purchasing power of the dollar declines.
 
LIQUIDITY:  Securities are said to be liquid when they can be easily bought or
sold in large volume without substantially affecting their price. Some
securities, such as private placements or stocks that have few shares
outstanding are considered illiquid either because there are few market
participants interested in buying or selling the securities or because purchases
and sales may cause wide price swings.
 
LOCAL CURRENCY TERMS:  Returns expressed in local currency terms show what
investors using that currency would have earned, without any adjustment for
differences in currency values. Returns expressed in U.S. dollar terms reflect
any differences in the relative value of the local currency and the U.S. dollar.
 
MANDATORY CONVERTIBLE PREFERRED:  A security that is similar to a common stock
with an enhanced yield feature. Generally, they perform more like modified
equities rather than true convertibles.
 
MERGERS AND ACQUISITIONS:  A merger is a combination of two companies. An
acquisition is the purchase of a company, division, or business unit. Companies
that are the subject of a merger or acquisition often pay shareholders a
premium, or an amount over the current share price, to complete the transaction
quickly and under favorable terms.
 
MORTGAGE-BACKED SECURITIES:  Securities representing interests in "pools" of
mortgages in which principal and interest payments by the holders of underlying
fixed- or adjustable-rate mortgages are, in effect, "passed through" to
investors (net of fees paid to the issuer or guarantor of the securities).
 
PAR VALUE:  The nominal or face value of a security.  A bond selling at par, for
example, is worth the same dollar value it was issued for or at which will be
redeemed at maturity. In price comparisons, 100 may be used to represent par
value, with higher or lower values representing premiums or discounts,
respectively.
 
PREMIUM:  The amount by which a bond sells above its face or par value. For
example, a bond with a face value of $1,000 would sell for a $100 premium when
it cost $1,100.
 
PRICE-TO-EARNINGS RATIO:  The price of a stock divided by its earnings per
share.
 
REAL ESTATE INVESTMENT TRUST (REIT):  A publicly traded company that manages a
portfolio of real estate properties for shareholders.
 
RECESSION:  A downturn in economic activity, typically defined by at least two
consecutive quarters of decline in a country's gross domestic product.
 
SPLIT ISSUES (SPLIT-RATED ISSUES):  Securities rated top tier by one credit
rating agency and second tier by another.
 
SUPPLY AND DEMAND:  In the bond market, supply is influenced by the amount of
new securities issued and the amount of bonds investors wish to sell. Demand
reflects the amount of bonds investors wish to buy, which may decrease when
other markets offer greater opportunities.
 
In the stock market, an oversupply of a product or service can reduce demand and
lower stock prices. When demand increases relative to supply, stock prices may
recover.
 
WEIGHTING:  The proportion of a portfolio allocated to a specific security,
market sector or country, i.e., a portfolio is said to be overweighted in a
sector or country when that portion of the portfolio is greater than the
sector's general relationship to the market as a whole or the country's total
equities relative to the international equity markets as a whole.
 
YANKEE ISSUES:  Dollar-denominated income securities issued in the United States
by foreign banks and corporations, usually when conditions in the U.S. are more
favorable than in other markets, including the issuer's domestic market
overseas.
 
YIELD:  The income per share (or current value of a security) paid to investors
over a specified period of time as a percentage of the cost of the security.
Mutual fund yields are expressed as a percentage of the fund's current price per
share.
 
                                       47
<PAGE>   48
 
YIELD CURVE:  When interest rates available from various short-, intermediate-,
and long-term securities are plotted on a graph, the resulting line is known as
a yield curve.
 
YIELD SPREAD:  The difference in yield between securities in different market
sectors, such as high yield securities and Treasury issues -- or between
different securities in a single sector, such as high yield bonds with different
credit ratings.
 
YIELD TO MATURITY:  A concept that reflects the rate of return an investor would
receive if an interest-bearing security were held to its maturity date.

NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
 
NOTE 1-- Organization and Accounting Policies:
- --------------------------------------------------------------------------------

NYLIAC Variable Annuity Separate Account-I ("Separate Account-I") and NYLIAC
Variable Annuity Separate Account-II ("Separate Account-II") were established
on October 5, 1992, under Delaware law by New York Life Insurance and Annuity
Corporation, a wholly-owned subsidiary of New York Life Insurance Company.
These accounts were established to receive and invest premium payments under
Non-Qualified Flexible Premium Multi-Funded Variable Retirement Annuity
Policies (Separate Account-I) and Qualified Flexible Premium Multi-Funded
Variable Retirement Annuity Policies (Separate Account-II) issued by New York
Life Insurance and Annuity Corporation. Separate Account-I policies are
designed to establish retirement benefits to provide individuals with
supplemental retirement income. Separate Account-II policies are designed to
establish retirement benefits for individuals who participate in qualified
pension, profit sharing or annuity plans. The policies are distributed by
NYLIFE Distributors Inc. and sold by registered representatives of NYLIFE
Securities Inc., both of which are wholly-owned subsidiaries of NYLIFE Inc.,
which is a wholly-owned subsidiary of New York Life Insurance Company. Separate
Account-I and Separate Account-II are registered under the Investment Company
Act of 1940, as amended, as unit investment trusts.
 
  The assets of Separate Account-I and Separate Account-II are invested in the
shares of the MainStay VP Series Fund, Inc., the Alger American Fund, the
Calvert Variable Series Inc. (formerly, "Acacia Capital Corporation"), the
Fidelity Variable Insurance Products Fund II, the Fidelity Variable Insurance
Products Fund, the Janus Aspen Series, the MFS Variable Insurance Trust, the
Morgan Stanley Universal Funds, Inc., the T. Rowe Price Equity Series, Inc. and
the Van Eck Worldwide Insurance Trust (collectively, "Funds"). These assets are
clearly identified and distinguished from the other assets and liabilities of
New York Life Insurance and Annuity Corporation.
 
  Separate Account-I and Separate Account-II offer the following twenty-six
variable Investment Divisions, with their respective fund portfolios, for
Policyowners to invest premium payments: MainStay VP Capital Appreciation,
MainStay VP Cash Management, MainStay VP Convertible, MainStay VP Government,
MainStay VP High Yield Corporate Bond, MainStay VP International Equity,
MainStay VP Total Return, MainStay VP Value, MainStay VP Bond, MainStay VP
Growth Equity, MainStay VP Indexed Equity, American Century Income & Growth,
Dreyfus Large Company Value, Eagle Asset Management Growth Equity, Lord Abbett
Developing Growth, Alger American Small Capitalization, Calvert Social Balanced
(formerly, "Calvert Socially Responsible"), Fidelity VIP II Contrafund, Fidelity
VIP Equity-Income, Janus Aspen Series Balanced, Janus Aspen Series Worldwide
Growth, MFS Growth With Income Series, MFS Research Series, Morgan Stanley
Emerging Markets Equity, T. Rowe Price Equity Income and Van Eck Worldwide Hard
Assets. Each Investment Division of the Separate Accounts will invest
exclusively in the corresponding Eligible Portfolio.
 
  Initial premium payments received are allocated to the MainStay VP Cash
Management Investment Division until 15 days after the policy issue date.
Thereafter, premium payments will be allocated to the Investment Divisions of
Separate Account-I or Separate Account-II in accordance with the Policyowner's
instructions. In addition, the Policyowner has the option to transfer amounts
between the Investment Divisions of Separate Account-I or Separate Account-II
and the Fixed Account of New York Life Insurance and Annuity Corporation.
 
  No Federal income tax is payable on investment income or capital gains of
Separate Account-I or Separate Account-II under current Federal income tax law.
 
  Security Valuation--The investments are valued at the net asset value of
shares of the respective Fund portfolios.
 
  Security Transactions--Realized gains and losses from security transactions
are reported on the identified cost basis. Security transactions are accounted
for as of the date the securities are purchased or sold (trade date).
 
  Distributions Received--Dividend income and capital gain distributions are
recorded on the ex-dividend date and reinvested in the corresponding portfolio.
 
  The preparation of financial statements in accordance with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts and disclosures in the financial statements. Actual
results could differ from those estimates.

NOTE 3--Mortality and Expense Risk Charges:
- --------------------------------------------------------------------------------
 
Separate Account-I and Separate Account-II are charged for administrative
services provided and the mortality and expense risks assumed by New York Life
Insurance and Annuity Corporation. These charges are made daily at an annual
rate of 1.30% of the daily net asset value of each Investment Division. The
amounts of these charges retained in the Investment Divisions represent funds
of New York Life Insurance and Annuity Corporation. Accordingly, New York Life
Insurance and Annuity Corporation participates in the results of each
Investment Division ratably with the Policyowners.

NOTE 4--Distribution of Net Income:

Separate Account-I and Separate Account-II do not expect to declare dividends
to Policyowners from accumulated net investment income and realized gains. The
income and gains are distributed to Policyowners as part of withdrawals of
amounts (in the form of surrenders, death benefits, transfers, or annuity
payments) in excess of the net premium payments.

NOTE 1-- Organization and Business:
- --------------------------------------------------------------------------------
 
MainStay VP Series Fund, Inc. (the "Company") was incorporated under
Maryland law on June 3, 1983. The Company is registered under the
Investment Company Act of 1940, as amended, ("Investment Company Act") as
an open-end diversified management investment company. American Century
Income & Growth, Dreyfus Large Company Value, Eagle Asset Management Growth
Equity and Lord Abbett Developing Growth Portfolios, which commenced operations
on May 1, 1998, Convertible Portfolio, which commenced operations on October 1,
1996, High Yield Corporate Bond, International Equity and Value Portfolios,
which commenced operations on May 1, 1995, Capital Appreciation, Cash
Management, Government, Total Return and Indexed Equity Portfolios, which
commenced operations on January 29, 1993 and Bond and Growth Equity Portfolios,
which commenced operations on January 23, 1984, (the "Funds"; each separately a
"Portfolio") are separate portfolios of the Company. Shares of the Funds are
currently offered only to New York Life Insurance and Annuity Corporation
("NYLIAC"), a wholly owned subsidiary of New York Life Insurance Company ("New
York Life"). NYLIAC allocates shares of the Funds to, among others, New York
Life Insurance and Annuity Corporation's Variable Annuity Separate Account-I and
Variable Annuity Separate Account-II (collectively "Separate Accounts"). The
Separate Accounts are used to fund multi-funded retirement annuity policies.
 
The investment objectives for each of the Portfolios of the Company are as
follows:
 
Capital Appreciation:  to seek long-term growth of capital.
 
Cash Management:  to seek as high a level of current income as is considered
consistent with the preservation of capital and liquidity.
 
Convertible:  to seek capital appreciation together with current income.
 
Government:  to seek a high level of current income, consistent with safety of
principal.
 
High Yield Corporate Bond:  to maximize current income through investment in a
diversified portfolio of high yield, high risk debt securities which are
ordinarily in the lower rating categories of recognized rating agencies.
 
International Equity:  to seek long-term growth of capital by investing in a
portfolio consisting primarily of non-U.S. equity securities.
 
Total Return:  to realize current income consistent with reasonable opportunity
for future growth of capital and income.
 
Value:  to realize maximum long-term total return from a combination of capital
growth and income.
 
Bond:  to seek the highest income over the long term consistent with
preservation of principal.
 
Growth Equity:  to seek long-term growth of capital with income as a secondary
consideration.
 
Indexed Equity:  to provide investment results that correspond to the total
return performance (reflecting reinvestment of dividends) of common stocks in
the aggregate, as represented by the S&P 500.
 
American Century Income & Growth:  to seek dividend growth, current income and
capital appreciation, primarily by investing in common stocks.
 
Dreyfus Large Company Value:  to seek capital appreciation by investing
principally in publicly-traded equity securities of domestic and foreign issuers
which are characterized as value companies by the sub-advisor.
 
Eagle Asset Management Growth Equity:  to seek growth through long-term capital
appreciation.
 
Lord Abbett Developing Growth:  to seek long-term growth of capital through a
diversified and actively-managed portfolio consisting of developing growth
companies, many of which are traded over the counter.
 
There are certain risks involved in investing in foreign securities that are in
addition to the usual risks inherent in domestic instruments. These risks
include those resulting from future adverse political and economic developments
and possible imposition of currency exchange blockages or other foreign
governmental laws or restrictions.

NOTE 2--Significant Accounting Policies:
- --------------------------------------------------------------------------------
 
The following is a summary of significant accounting policies followed by the
Company:
 
                                      (A)
 
VALUATION OF FUND SHARES. The net asset value per share of each Portfolio is
calculated on each day the New York Stock Exchange (the "Exchange") is open for
trading as of the close of regular trading on the Exchange. The net asset value
per share is calculated for each Portfolio by dividing the current market value
(amortized cost, in the case of Cash Management Portfolio) of the Portfolio's
total assets, less liabilities, by the total number of outstanding shares of
that Portfolio.
 
                                      (B)
 
SECURITIES VALUATION. Portfolio securities of Cash Management Portfolio are
valued at amortized cost, which approximates market value. The amortized cost
method involves valuing a security at its cost on the date of purchase and
thereafter assuming a constant amortization to maturity of the difference
between such cost and the value on maturity date.
 
Securities of each of the other Portfolios are stated at value determined (a) by
appraising common and preferred stocks which are traded on the Exchange at the
last sale price on that day or, if no sale occurs, at the mean between the
closing bid and asked prices, (b) by appraising common and preferred stocks
traded on other United States national securities exchanges or foreign
securities exchanges as nearly as possible in the manner described in (a) by
reference to their principal exchange, including the National Association of
Securities Dealers National Market System, (c) by appraising over-the-counter
securities quoted on the National Association of Securities Dealers NASDAQ
system (but not listed on the National Market System) at the bid price supplied
through such system, (d) by appraising over-the-counter securities not quoted on
the National Association of Securities Dealers NASDAQ system and securities
listed or traded on certain foreign exchanges whose operations are similar to
the U.S. over-the-counter market, at prices supplied by the pricing agent or
brokers selected by the Adviser if these prices are deemed to be representative
of market values at the regular close of business of the Exchange, (e) by
appraising debt securities at prices supplied by a pricing agent selected by the
Adviser, whose prices reflect broker/dealer supplied valuations and electronic
data processing techniques if those prices are deemed by the Adviser to be
representative of market values at the regular close of business of the
Exchange, (f) by appraising options and futures contracts at the last sale price
on the market where such options or futures contracts are principally traded,
and (g) by appraising all other securities and other assets, including debt
securities for which prices are supplied by a pricing agent but are not deemed
by the Adviser to be representative of market values, but excluding money market
instruments with a remaining maturity of sixty days or less and including
restricted securities and securities for which no market quotations are
available, at fair value in accordance with procedures approved by the
Directors. Short-term securities which mature in more than 60 days are valued at
current market quotations. Short-term securities which mature in 60 days or less
are valued at amortized cost if their term to maturity at purchase was 60 days
or less, or by amortizing the difference between market value on the 61st day
prior to maturity and value on maturity date if their original term to maturity
at purchase exceeded 60 days.
 
Events affecting the values of certain portfolio securities that occur between
the close of trading on the principal market for such securities (foreign
exchanges and over-the-counter markets) and the regular close of the Exchange
will not be reflected in the Portfolios' calculations of net asset values unless
the Adviser believes that the particular event would materially affect net asset
value, in which case an adjustment would be made.
 
                                      (C)
 
FORWARD FOREIGN CURRENCY CONTRACTS. A forward foreign currency contract is an
agreement to buy or sell currencies of different countries on a specified future
date at a specified rate. During the period the forward contract is open,
changes in the value of the contract are recognized as unrealized gains or
losses by "marking to market" such contract on a daily basis to
 
                                       181
 

<PAGE>   182
NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED)
 
reflect the market value of the contract at the end of each day's trading. When
the forward contract is closed, the Portfolio records a realized gain or loss
equal to the difference between the proceeds from (or cost of) the closing
transaction and the Portfolio's basis in the contract. The High Yield Corporate
Bond and International Equity Portfolios enter into forward foreign currency
contracts in order to hedge their foreign currency denominated investments and
receivables and payables against adverse movements in future foreign exchange
rates.
 
The use of forward contracts involves, to varying degrees, elements of market
risk in excess of the amount recognized in the statement of assets and
liabilities. The contract amount reflects the extent of the Portfolio's
involvement in these financial instruments. Risks arise from the possible
movements in the foreign exchange rates underlying these instruments. The
unrealized appreciation (depreciation) on forward contracts reflects the
Portfolio's exposure at period-end to credit loss in the event of a
counterparty's failure to perform its obligations.

                                      (D)
 
FUTURES CONTRACTS. A futures contract is an agreement to purchase or sell a
specified quantity of an underlying instrument at a specified future date and
price, or to make or receive a cash payment based on the value of a securities
index. During the period the futures contract is open, changes in the value of
the contract are recognized as unrealized gains or losses by "marking to market"
such contract on a daily basis to reflect the market value of the contract at
the end of each day's trading. 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 are known as "variation margin". When the
futures contract is closed, the Portfolio records a realized gain or loss equal
to the difference between the proceeds from (or cost of) the closing transaction
and the Portfolio's basis in the contract. The Indexed Equity Portfolio invests
in stock index futures contracts to gain full exposure to changes in stock
market prices to fulfill its investment objective.
 
The use of futures contracts involves, to varying degrees, elements of market
risk in excess of the amount recognized in the statement of assets and
liabilities. The contract or notional amounts and variation margin reflect the
extent of the Portfolio's involvement in open futures positions. Risks arise
from the possible imperfect correlation in movements in the price of futures
contracts and the underlying hedged assets, and the possible inability of
counterparties to meet the terms of their contracts. However, the Portfolio's
activities in futures contracts are conducted through regulated exchanges which
minimize counterparty credit risks.
 
                                      (E)
 
SECURITY TRANSACTIONS AND INVESTMENT INCOME. The Company records security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method and include gains
and losses from repayments of principal on mortgage related and other
asset-backed securities. Dividend income is recognized on the ex-dividend date
and interest income is accrued daily except when collection is not expected.
Discounts on securities purchased for all Portfolios are accreted on the
constant yield method over the life of the respective securities or, if
applicable, over the period to the first call date. Premiums on securities
purchased are not amortized for any Portfolio except Cash Management Portfolio
which amortizes the premium on the constant yield method over the life of the
respective securities.
 
                                      (F)
 
FOREIGN CURRENCY INVESTING. The books and records of the Company are recorded in
U.S. dollars. Foreign currency amounts are translated into U.S. dollars at the
mean between the buying and selling rates last quoted by any major U.S. bank at
the following dates:
 
        (i) market value of investment securities, other assets and
            liabilities--at the valuation date,
 
       (ii) purchases and sales of investment securities, income and
            expenses--at the date of such transactions.
 
The assets and liabilities of High Yield Corporate Bond and International Equity
Portfolios are presented at the exchange rates and market values at the close of
the period. The changes in net assets arising from fluctuations in exchange
rates and the changes in net assets resulting from changes in market prices are
not separately presented. However, gains and losses from certain foreign
currency transactions are treated as ordinary income for Federal income tax
purposes.
 
Net realized gain (loss) on foreign currency transactions represents net gains
and losses on forward currency contracts, net currency gains or losses realized
as a result of differences between the amounts of securities sale proceeds or
purchase cost, dividends, interest and withholding taxes recorded on the
Portfolio's books and the U.S. dollar equivalent amount actually received or
paid. Net currency gains or losses from valuing foreign currency denominated
assets and liabilities, other than investments, at period-end exchange rates are
reflected in unrealized foreign exchange gains (losses).

MORTGAGE DOLLAR ROLLS. Certain of the Portfolios enter into mortgage dollar roll
transactions ("MDRs") in which they sell mortgage backed securities ("MBS") from
their portfolio to a counterparty from whom they simultaneously agree to buy a
similar security on a delayed delivery basis. The MDR transactions of the
Portfolios are classified as purchase and sale transactions. The securities sold
in connection with the MDRs are removed from the portfolio and a realized gain
or loss is recognized. The securities the Portfolios have agreed to acquire are
included at market value in the portfolio of investments and liabilities for
such purchase commitments are included as payables for investments purchased.
The Portfolios maintain a segregated account with the custodian containing
securities from the respective portfolios having a value not less than the
repurchase price, including accrued interest. MDR transactions involve certain
risks, including the risk that the MBS returned to the Portfolios at the end of
the roll, while substantially similar, could be inferior to what was initially
sold to the counterparty.
 
                                      (H)
 
RESTRICTED SECURITIES. A restricted security is a security which has been
purchased through a private offering and cannot be resold to the general public
without prior registration under the Securities Act of 1933. Disposal of these
securities may involve time-consuming negotiations and expense, and prompt sale
at an acceptable price may be difficult. The issuers of the securities will bear
the costs involved in registration under the Securities Act of 1933 and in
connection with the disposition of such securities. The Convertible, High Yield
Corporate Bond and Total Return Portfolios do not have the right to demand that
such securities be registered. The Portfolios may not invest more than 15%, 10%
and 15%, respectively, of their net assets in illiquid securities.

SECURITIES LENDING. The Portfolios may lend their securities to broker-dealers
and financial institutions. The loans are secured by collateral (cash or
securities) at least equal at all times to the market value of the securities
loaned. The Portfolios may bear the risk of delay in recovery of, or loss of
rights in, the securities loaned should the borrower of the securities fail
financially. The Portfolios receive compensation for lending their securities in
the form of fees or they retain a portion of interest on the investment of any
cash received as collateral. The Portfolios also continue to receive interest
and dividends on the securities loaned, and any gain or loss in the market price
of the securities loaned that may occur during the term of the loan will be for
the account of the Portfolios.

FINANCIAL INSTRUMENTS WITH CONCENTRATION OF CREDIT RISK. High Yield Corporate
Bond Portfolio invests in Loan Participations. When the Portfolio purchases a
Participation, the Portfolio typically enters into a contractual relationship
with the lender or third party selling such Participation ("Selling
Participant"), but not with the Borrower. As a result, the Portfolio assumes the
credit risk of the Borrower, the Selling Participant and any other persons
interpositioned between the Portfolio and the Borrower ("Intermediate
Participants"). The Portfolio may not directly benefit from the collateral
supporting the Senior Loan in which it has purchased the Participation. The
Portfolio may be considered to have a concentration of credit risk in the
banking industry, since the Portfolio will only acquire Participations if the
Selling Participant and each Intermediate Participant is a financial
institution.
 
                                      (L)
 
FEDERAL INCOME TAXES. Each of the Portfolios is treated as a separate entity for
Federal income tax purposes. The Company's policy is to comply with the
requirements of the Internal Revenue Code applicable to regulated investment
companies and to distribute all of the taxable income to the shareholders of
each Portfolio within the allowable time limits. Therefore, no Federal income
tax provision is required.
 
Investment income received by a Portfolio from foreign sources may be subject to
foreign income taxes withheld at the source.

DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are
recorded on the ex-dividend date. For Cash Management Portfolio, dividends are
declared daily and paid monthly. Each of the other Portfolios intends to declare
and pay, as a dividend, substantially all of their net investment income and net
realized gains no less frequently than once a year. Income dividends and capital
gain distributions are determined in accordance with Federal income tax
regulations which may differ from generally accepted accounting principles.
 
                                      (N)
 
ORGANIZATION COSTS. Costs incurred in connection with the initial organization
and registration of a Portfolio of the Company are amortized over a maximum
period of 60 months beginning with the commencement of operations of the
respective Portfolio. Organization costs for American Century Income & Growth,
Dreyfus Large Company Value, Eagle Asset Management Growth Equity and Lord
Abbett Developing Growth Portfolios, paid by, and reimbursable to, NYLIAC,
aggregated approximately $73,000. Such costs are being amortized beginning with
the commencement of operations of the respective Portfolios on May 1, 1998. In
the event that any of the initial shares purchased by NYLIAC are redeemed,
proceeds of such redemption will be reduced by the proportionate amount of the
unamortized deferred organizational expenses which the number of shares redeemed
bears to the total number of initial shares purchased.
 
                                      (O)
 
EXPENSES. Expenses with respect to the Company are allocated to the individual
Portfolios in proportion to the net assets of the respective Portfolios when the
expenses are incurred except when direct allocations of expenses can be made.
 
                                      (P)
 
USE OF ESTIMATES. The preparation of financial statements in accordance with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts and disclosures in the
financial statements. Actual results could differ from those estimates.

NOTE 5--Financial Investments:
- --------------------------------------------------------------------------------
 
High Yield Corporate Bond Portfolio invests primarily in high yield bonds. These
bonds may involve special risks in addition to the risks associated with
investment in higher rated debt securities. High yield bonds may be more
susceptible to real or perceived adverse economic and competitive industry
conditions than higher grade bonds. Also, the secondary market on which high
yield bonds are traded may be less liquid than the market for higher grade
bonds.
 
- --------------------------------------------------------------------------------
NOTE 6--Portfolio Securities Loaned:
- --------------------------------------------------------------------------------
 
At June 30, 1998, Government and Total Return Portfolios had portfolio
securities with a fair market value of $19,499,863 and $61,413,856, respectively
on loan to broker-dealers and government securities dealers.
 
Cash collateral received by Government and Total Return Portfolios is invested
in investment grade commercial paper, or other securities in accordance with the
Portfolios securities lending procedures. Such investments are included as an
asset and a corresponding liability in the Statement of Assets and Liabilities.
While the Portfolios invest cash collateral in investment grade securities or
other "high quality" investment vehicles, the Portfolios bear the risk that
liability for the collateral may exceed the value of the investment.
 
Net income earned on securities lending amounted to $29,573 and $62,431, net of
broker fees and rebates, respectively, for the six month period ended June 30,
1998, which is included as interest income on the Statement of Operations.

NOTE 7--Line of Credit:
- --------------------------------------------------------------------------------
 
Capital Appreciation, Cash Management, Convertible, Government, High Yield
Corporate Bond, International Equity, Total Return, Value and Indexed Equity
Portfolios maintain a line of credit with The Bank of New York in order to
secure a source of funds for temporary purposes to meet unanticipated or
excessive shareholder redemption requests. There was no outstanding balance on
this line of credit at June 30, 1998.
