This Annual Report contains current performance information, financial

YEAR END REVIEW
 
The United States stock market delivered an unprecedented third year of gains
exceeding 20 percent. The remarkable combination of rapid economic growth and
slowing inflation has continued for another year. The Dow Jones Industrial
Average(1) closed the year at 7,908 up 24.9%, following 26.0% in 1996 and 33.5%
in 1995. The Standard & Poor's 500 Composite Stock Price Index(2) showed an even
stronger 33.4% return, ending the year at 970.
 
The unemployment rate declined from 5.3% in 1996 to 4.7%, the lowest rate since
1973 and well below levels previously associated with accelerating inflation.
Despite this, inflation continued to trend downward, with the Consumer Price
Index(3) (CPI) rising by just 1.7% in 1997. Faster increases in wage rates were
generally offset by slower increases in benefit costs, and rising productivity
held down unit labor costs. The rising dollar was another source of downward
pressure on prices.
 
In 1998, growth is expected to finally slow from its unsustainable pace without
any Federal Reserve Board tightening as the Asian currency crisis reduces
exports, raises imports, and moderates corporate profitability growth and
capital investment. Inflation should remain contained as the unemployment rate
begins to drift upward again and lower import prices restrain domestic prices as
well. Bond yields could fall further, and the next move by the Federal Reserve
Board may well be an easing of monetary policy.
 
The bull market for domestic equities has been driven by the continuation of
strong growth, healthy earnings gains, and low inflation. Market conditions for
1998 are likely to be mixed. Increased uncertainty about the impact of the Asian
crisis on individual companies could weigh on the market, and slower growth and
increased pricing competition from abroad could slow earnings.
 
VARIABLE ANNUITIES IN GENERAL
 
People are living longer and spending more time in retirement than ever before.
In fact, since the turn of the century, average life expectancy has increased
60%. Many people entering their retirement years can expect to spend fifteen,
twenty, perhaps even thirty years, or more, enjoying the rest of their lives.
Variable annuities can be an effective retirement planning tool because they
offer the benefits of tax deferral(4), an option for a lifetime income, an
enhanced death benefit and tax-free transfers between investment options and
other product features that set them apart from other taxable investment
vehicles.
 
New York Life Insurance and Annuity Corporation received over $1.5 billion in
variable annuity premiums in 1997, a 41% increase over the amount received in
1996. Total United States variable annuity sales reached over $85 billion in
1997, a 23% increase over 1996. Sales of variable annuities are expected to
continue to rise in 1998.

ADVISER'S REPORT
 
Market Overview
 
What a year: In 1997, the U.S. economy reveled in strong 3.7% growth, mild 2%
inflation, 4.7% unemployment, low interest rates, strong corporate profits, and
a seemingly unstoppable stock market. The year completed an unprecedented three
year run of above twenty percent returns for the stock market, with the Dow
Jones Industrial Average(1) returning 24.91%, the S&P 500(2) returning 33.36%,
and the NASDAQ(3) returning 21.64%. These stellar returns were accompanied by
increased volatility, with the industrial average moving more than 1 percent for
almost one third of all trading sessions in 1997. For the fourth quarter the Dow
Jones Industrial Average lost 0.02%, the S&P 500 eked out a positive return of
2.87% and the NASDAQ lost 6.84% as the technology sector slipped.
 
Only a few months ago, it looked as if fund managers might do something in 1997
they haven't done since 1993: beat the Standard & Poor's 500-stock index and the
index funds that mimic it. But the October market turmoil and the December
massacre in technology stocks put the Portfolios back behind the index.
 
Gross Domestic Product(4) increased almost 4 percent last year because of
consumer spending and business outlays for new equipment. As a result, corporate
profits increased and were at their highest level since the 1960s. However, 1997
continued to be a tale of two stock markets, with large stocks contributing most
heavily to the year's return, while smaller stocks trailed substantially. Best
performing industries included securities brokers, broadcasting, savings and
loans, advertising, airlines, home construction, trucking and oil-field
equipment. Worst performing industries included footwear, precious metals, heavy
construction, coal, casinos and health care. The average U.S. equity mutual fund
returned 24.36%, a very strong return when compared to the long-term historical
average of approximately 10%. Investors continued to pour assets into stock
funds, with almost $200 billion being invested through the end of October.
 
The year was not without weaknesses. Cracks appeared in August, with some
corporations announcing disappointing earnings. Then on October 27, the
industrial average plummeted 554.26 points, or 7.18%, its largest point drop
ever and biggest in percentage terms since 1987's Black Monday. International
investors' mettle was tested as the Southeast Asia "flu", which started with
Thailand floating the baht, soon spread to Malaysia, Philippines, Indonesia and
South Korea. Portfolios investing in Pacific Rim stock markets outside Japan
lost 35.52% in 1997, according to Lipper(5) Analytical Services, Inc. Latin
America and Eastern Europe were impacted as well, and U.S. investors became
jittery as they realized how intertwined the world's economies had become. The
Asian crisis has shifted investors' focus from U.S. economic strengths, to its
weaknesses. However, U.S. economic strength prevailed through the end of 1997.
 
The bond market ended 1997 on a high note as investors focused on future
prospects for Asian financial stability. Treasury securities have even
outperformed the Dow Jones Industrial Average since the middle of the year.
During the year, despite the surging economy and the lowest unemployment rate of
the last 24 years, which usually translate into higher prices, inflation
remained subdued. Any fears that the Federal Reserve Board would raise
short-term interest rates were put to rest by Asian financial turmoil. Prospects
of cheaper imports because of cheaper foreign currencies, low inflation, and the
higher foreign demand for U.S. Treasuries caused the bond market to rally.
Investors increased their contributions to bond mutual funds, with November
inflows approximately $8 billion versus $3.7 billion for October.
 
The U.S. dollar strengthened dramatically through 1997, with fundamental support
coming from the surging U.S. economy, high U.S. interest rates (compared with
other countries), low inflation and a high level of confidence in the Federal
Reserve. Foreign demand for U.S. assets drove the dollar to a five-year high
against the yen, eight-year high against the German mark and a four-year high
against the Swiss franc. In the latter part of 1997, foreign buying of U.S.
securities became a flood as the Asian financial crisis boosted the dollar's
image as a "safe haven".

Going forward, most economists see a slow growing economy, mild inflation and
low interest rates. More specifically, expectations for the stock market are
more muted with projections of 8% to 10% appreciation, which is more in line
with historical norms. Risks to this rosy picture include a continuing slide of
Southeast Asian financial markets impacting world economic growth, and even
possibly deflation, not an economic scenario since the 1930s. On the other hand,
a faster than expected recovery of the Asia markets could place more focus on
our domestic marketplace and could lead to inflationary concerns heating up.
 
General demographic trends and macroeconomic themes will continue into 1998.
Companies will continue to globalize, and competition will make price hikes
untenable. Productivity should continue to increase through technology advances
and improved utilization of resources. Baby boomers should continue to pour
money in the market for their retirement.

NEW YORK LIFE INSURANCE COMPANY
 
ADVISER'S REPORT
 
1997 In Review and 1998 Outlook
 
The U.S. financial markets produced another year of stellar performance in 1997.
The economy was strong, with Gross Domestic Product(1) growing at a 4.3%
annualized pace in the fourth quarter. Corporate profits enjoyed continued
strength and inflationary pressures remained subdued, with inflation running at
1.7% during the year. These positive factors led to outstanding stock market
performance, with the S&P 500 Index(2) up by 33.4%, and to strong bond market
results with the Salomon Bond Investment Grade Index(3) up by 9.6%.
 
Nevertheless, during the year, the tone of the financial markets changed and
became more volatile. Due to relatively high valuations, the stock market was
unforgiving of negative earnings surprises, and certain industry group sectors,
such as technology, fell in and out of favor. Volatility in the bond market
increased several times during the year as strong economic growth and employment
statistics led to fears of increasing inflation.
 
This environment changed radically as the Asian debt crisis began to unfold in
the fourth quarter. The inability of several Asian countries to keep their
currencies pegged to the dollar, combined with massive borrowing, has reduced
the growth outlook for the worldwide economy. Near term, foreign investors have
been attracted to the U.S. as a safe haven. Longer term, U.S. corporate earnings
are bound to suffer. While certain sectors such as retail, soft goods and
personal computers may benefit from a lower cost of goods, the reduced demand
from the Asian economies combined with intensified pricing pressures in other
economic sectors, may prove more powerful.
 
Our outlook is positive for interest rates, since the inflationary pressures
associated with rapid domestic economic growth should be offset by intensified
price pressure from abroad. We do see the possibility that the Asian crisis may
mask underlying inflationary trends in the U.S. economy.
 
Implications for the stock market are somewhat negative, as corporate pricing
and earnings power may be damaged. Thus we are somewhat subdued going into 1998.
We believe that sectors benefiting from lower interest rates such as financials,
and from significant product innovation and industry consolidation, such as
pharmaceutical companies, will provide opportunities for investment.

MAINSTAY VP CASH MANAGEMENT PORTFOLIO
 
1997 MARKET HIGHLIGHTS
- - Strong economic growth led to a Federal Reserve Board (the "Fed") move to
  raise interest rates 25 basis points at the end of March, but with the crisis
  in Asia, expectations for growth slowing in the U.S. and inflation under
  control, the Fed took no further action.
- - Throughout the year, the short-term markets were primarily driven by
  investor's expectations for interest rates and inflation.
- - Longer-maturity money market securities provided higher yields than
  short-dated issues throughout most of the year.
- - Volatility was minimal throughout the year, but upsets in Asian markets in the
  third and fourth quarters of 1997 caused a flight to high-quality securities.
 
1997 PORTFOLIO HIGHLIGHTS
- - For the year ended 12/31/97, the MainStay VP Cash Management Portfolio
  returned 5.25%.
- - The Portfolio benefited from a short average maturity in the first quarter and
  a neutral to long average maturity throughout the rest of the year.
- - The Portfolio outperformed the average Lipper(1) money market fund for the
  year ended 12/31/97 as well as for the 3-year and since-inception periods.
 
PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS
Perhaps the single most important influence on the MainStay VP Cash Management
Portfolio in 1997 was investor expectations about the direction of interest
rates and inflation. Seeking to slow rapid economic growth and ward off
inflation, the Fed moved to raise interest rates 25 basis points at the end of
March. While market participants speculated on whether the Fed would tighten
again, no other moves materialized throughout the year. As a result, portfolios
with a short average maturity in the first quarter and a longer average maturity
thereafter were in the best position to benefit from interest rate
opportunities.
 
In the third and fourth quarters, financial markets throughout Asia experienced
severe setbacks, catching many investors off guard. The resulting flight to
quality increased demand for top-tier securities.
 
GIVEN THIS CONTEXT, HOW DID THE MAINSTAY VP CASH MANAGEMENT PORTFOLIO DO IN
1997?
For the six-month, 1-year, and since-inception periods, the Portfolio
outperformed the average Lipper money market fund.
 
HOW DID THE PORTFOLIO MANAGE TO DO SO WELL?
We used a variety of tools to accomplish our objective. Of course, one of the
most important determinants of performance in the MainStay VP Cash Management
Portfolio is average maturity. In the first quarter, we saw no yield advantage
to lengthening the Portfolio's maturity and stayed relatively short. That proved
beneficial when the Fed moved to raise interest rates in March. After that, we
lengthened our average maturity and kept it neutral to long throughout the rest
of the year.
 
WHY DID YOU LENGTHEN MATURITIES?
Despite widespread speculation about whether the Fed would tighten interest
rates again, we kept our eye on the economic data and saw no conclusive evidence
that they would have to take additional action. We kept the Portfolio longer
than what we took to be the average number of days to maturity in our peer
group.
 
HOW MUCH LONGER DID YOU GO?
Once again, it varied. Rates were not absolutely stable, so our days to maturity
varied. While the average portfolio may have varied from 40 to 60 days to
maturity, we tended to hold in a range from 40 to 75 days. At times, we believe
we were up to 15 days longer than the average fund, which, as it happens, was
always positive for our performance.
 
HOW DID YOU SEEK TO ENHANCE YIELDS THROUGHOUT THE YEAR?
During the first half of 1997, we used our extensive research to seek out
securities with features that could offer potential yield advantages. We found
asset-backed securities, callable certificates of deposit ("CDs"), and Yankee
issues attractive. Later in the year, we reduced our positions in most of these
areas.
 
                                        6
<PAGE>   7
 
WHY DID YOU CUT BACK?
They simply became less attractive. Callable CDs became less popular as the
market became more volatile and issuance declined, so in the second and third
quarters we simply let our issues mature. We've continued to invest in some
top-tier asset-backed securities, which may offer yield opportunities and are
often backed by a letter of credit from a leading bank. We continue to hold a
number of Yankee issues, which are dollar denominated securities issued in the
United States by foreign banks and corporations.
 
DOES THE PORTFOLIO HOLD ONLY DOMESTIC SECURITIES?
No. The Portfolio has a global exposure, including European, South American, and
Mexican issuers backed by European banks. We're focusing on top-tier credits and
dollar denominated issues. We didn't own anything in Thailand, Malaysia, or
Indonesia. We don't take any currency risk in the Portfolio. Though the
Portfolio is allowed to hold some split issues and second-tier credits, the
Portfolio is currently invested only in top-tier securities.
 
HOW DO INVESTORS BENEFIT FROM GLOBAL DIVERSIFICATION?
We seek broad diversification within the range of issues and maturities that are
available to us. Using top-tier securities from around the world helps reduce
our exposure to the risks of any single issuer or market. At the same time, it
helps us pursue higher yields among securities with top quality and a high
degree of liquidity.
 
WHAT DO YOU ANTICIPATE IN 1998?
Given the dynamics of the Asian crisis, consensus on Fed policy changes rapidly.
However, we believe U.S. monetary policy will focus on the U.S. economy, not on
the bailing out of Asia. We believe the Portfolio is well positioned with a
broad spectrum of maturities, a broad range of issuers, and a relatively long
average maturity that will benefit investors if rates continue to decline.
Whatever happens, we'll continue to focus on high quality, as we seek as high a
level of current income as is consistent with the preservation of capital and
liquidity.

MAINSTAY VP BOND PORTFOLIO
 
1997 MARKET HIGHLIGHTS
 
- - The theme for the fixed income market in 1997 was benign inflation in spite of
  solid economic growth.
 
- - The Federal Reserve Board (the "Fed") maintained a stable monetary policy
  after a 25 basis point tightening in March.
 
- - The market experienced a significant rally for the year with the 30 year U.S.
  Treasury bond declining 72 basis points.
 
- - Events in Asia had a profound effect on U.S. Government securities and various
  investment grade and non-investment grade corporate securities.
 
1997 PORTFOLIO HIGHLIGHTS
 
- - For the year ended 12/31/97, the MainStay VP Bond Portfolio returned 9.65%.
 
- - The Portfolio outperformed the average A rated corporate bond fund in its
  Lipper(1) universe by 49 basis points.
 
- - The Portfolio ranked 8th out of 28 bond funds (top 28.6%) for its Lipper
  category.
 
- - An average portfolio quality of at least AA- was maintained throughout the
  year, limiting credit risk.
 
PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS
 
Interest rates rose early in 1997 as market participants were concerned about an
overheating economy and a restrictive Fed. Toward the middle of the year market
sentiment shifted as investors focused on an improving budget deficit and mild
inflation statistics. The latter part of the year was dominated by the Asian
financial crisis. Many global equity markets experienced drastic declines. The
flight to quality trading caused a significant rally in U.S. Treasury
securities.
 
TO WHAT DO YOU ATTRIBUTE THE PORTFOLIO'S POSITIVE PERFORMANCE?
 
During the course of the year, the Portfolio maintained a credit barbell where
weightings were concentrated in AAA securities and lower-quality domestic
corporates which we viewed to be stable with strong relative value
characteristics. This structure worked well as lower quality corporates
outperformed within the investment grade sector. The Portfolio also had minimal
exposure to assets that would have been adversely influenced by the turmoil in
Asia. Additionally, our high quality assets benefited from the flight to quality
trading precipitated by the financial distress in Asia.
 
WHAT WAS YOUR PRIMARY STRATEGY DURING 1997?
 
The Portfolio shifted assets from the government sector to the corporate and
mortgage sectors in an effort to enhance yield and add return in a low interest
rate environment.
 
HOW WILL YOU ANTICIPATE MANAGING THE PORTFOLIO IN A SLOW GROWTH ENVIRONMENT?
 
In the corporate sector we will concentrate on non-cyclicals such as consumer
products, utilities and pipelines. We feel the bank and finance sector has
limited downside and could benefit from lower interest rates. In the mortgage
sector we will manage pre-payment risk based on our prevailing interest rate
forecast.
 
WHERE DO YOU PERCEIVE RISK IN THE PORTFOLIO?
 
Our adjustments during the year added some credit and call risk to the
Portfolio. However, the Portfolio's overall credit quality and structure
continues to be consistent with our long-term conservative approach to managing
the Portfolio.
 
                                        8
<PAGE>   9
 
WHAT IS YOUR OUTLOOK FOR THE FIXED INCOME MARKET IN 1998?
We expect slower economic growth, along with continued low levels of inflation.
Recent events in Asia should depress domestic growth, putting downward pressure
on inflation, interest rates, and corporate earnings. The Asian debacle may have
taken a Fed tightening out of the market for 1998. Corporate bond and mortgage-
backed security spread widening, resulting from supply pressure, low interest
rates and global dislocation, should create investment opportunities in 1998.

MAINSTAY VP GROWTH EQUITY (COMMON STOCK) PORTFOLIO
 
1997 MARKET HIGHLIGHTS
- - The market recorded an unprecedented third consecutive year of 20% plus gains.
- - Low inflation coupled with favorable interest rates supported equity
  valuations.
- - In general, earnings exceeded most investor's expectations.
- - Strong inflows into equity mutual funds, solid demand for U.S. equities from
  foreign institutional investors and record levels of merger and acquisition
  activity created an excellent supply/demand environment for stocks.
- - Large capitalization issues were the market's best performers.
 
1997 PORTFOLIO HIGHLIGHTS
- - For the year ended 12/31/97, the MainStay VP Growth Equity Portfolio returned
  26.75%.
- - Financial stocks were among the Portfolio's best performers owing primarily to
  the strong bond market.
- - Consumer issues also displayed impressive gains throughout the year as wage
  growth began to improve.
- - The Portfolio outperformed the Lipper(1) growth fund average return for the
  year but underperformed the S&P 500(2) Index.
 
PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS
For the third year in a row, the U.S. equity market generated robust results.
However, 1997 was differentiated from the prior two years by an increase in
market volatility. The market experienced corrections in March and October, but
managed to rebound rather quickly from these setbacks, keeping the current bull
market intact. The volatility appeared severe due to the steadiness of gains the
previous two years and the complacency which resulted from this stability.
However, history shows the volatility of the market in 1997 was not an anomaly
as equity markets have historically experienced choppiness in returns.
 
The majority of 1997's gains were recorded in the second and third quarters as
investors became more comfortable with the economy. The fear of higher interest
rates and rising inflation which caused March's correction dissipated quickly,
as strong employment reports did not bring about expected price increases. In
fact, it had a more positive effect on the economy as improving wages spurred an
increase in consumer spending; albeit at a modest rate. These factors along with
steadily growing corporate earnings created a near-perfect economic scenario.
 
Approaching year-end 1997, investors long time fear of inflation made a 180
degree turn as Asia's economic problems introduced the fear of deflation as an
issue. In October, a correction in the market was triggered by currency
devaluations and financial liquidity concerns in Asia. While we believe that
certain segments of the economy will definitely be impacted by deflationary
pressures, the impact of this trend is not likely to have a devastating effect
on the U.S. market.
 
CAN YOU DISCUSS THE MAINSTAY VP GROWTH EQUITY PORTFOLIO'S PERFORMANCE?
For the year ended 12/31/97, the MainStay VP Growth Equity Portfolio had a total
return of 26.75%. This placed us solidly ahead of the Lipper growth fund average
return of 25.36%. This marked the fifth time in the last six years that we have
outperformed the Lipper growth fund average. However, we lagged the S&P 500
return of 33.36%.
 
WHY DID THE AVERAGE LIPPER GROWTH FUND UNDERPERFORM THE S&P 500?
The Lipper growth fund average underperformed the S&P 500 because of the
superior relative performance of a narrow number of large capitalization issues.
In fact, the top ten performing stocks in the S&P 500 accounted for more than
one quarter of its gain. Active portfolio managers tend to underweight the S&P
500's larger companies in relation to the size of their portfolios. For example,
owning the twenty largest companies in the S&P 500 would greatly skew the
balance of an actively managed portfolio. Outperformance of these "nifty fifty"
names is common in the late stage of an earnings cycle as investors perceive
these stocks being safer than the market as a whole.
 
WHAT WERE THE BIGGEST FACTORS LEADING TO THE PORTFOLIO'S POSITIVE PERFORMANCE?
There were several factors which supported the Portfolio's solid performance.
First, our technology holdings performed exceptionally as our focus on more
software related and computer service companies was particularly rewarding.
Second, our overweighted position in financial stocks was extremely profitable
as that sector out-
 
                                       10
<PAGE>   11
 
performed the market by a wide margin. Finally, our underweighting of the
cyclical basic materials sector was timely as these stocks were among the
market's worst performers.
 
WHICH STOCKS WERE THE LARGEST CONTRIBUTORS TO THE PORTFOLIO'S RETURNS?
Three of the Portfolio's largest positions -- General Electric, Lilly (Eli) and
Kroger had excellent performance as each stock had total returns in excess of
50%. General Electric's strong performance stemmed from the consistency of its
earnings and its ability to maintain profit margins. Lilly's (Eli) performance
benefited from the introduction of a couple of blockbuster drugs combined with a
valuation upgrade of the pharmaceutical industry. Kroger, the country's largest
supermarket operator, was finally awarded a higher valuation consistent with its
earnings growth prospects.
 
Some other stocks which were strong contributors to our performance included:
Costco, a warehouse store operator; Halliburton, in the oil and energy service
industry; Compuware, an enterprise software company; and Freddie Mac, a
residential mortgage company.
 
WHAT WERE YOUR BIGGEST DISAPPOINTMENTS IN 1997?
Some of our smaller-capitalization holdings had a difficult year in 1997. It is
our strategy to make sure that our smaller issues have lower weightings in the
Portfolio due to the higher risk/reward profile attached to such holdings. For
instance, Danka Business Systems, a stock we recently held, preannounced a
disappointing quarter. The stock lost half of its market value that day.
However, its low weight in the Portfolio helped to mitigate some of the damage
in our returns.
 
WHAT IS YOUR OUTLOOK FOR THE EQUITY MARKET IN 1998?
After three years of extraordinary gains we believe 1998 will return to more
moderate gains. We expect interest rates to remain subdued and continue to
provide support for the equity market. Our main concern is that earnings
expectations for 1998 are probably too high and are subject to downward
revisions. Under such a situation we expect continued volatility in the market
as earning numbers come under more scrutiny. We expect that companies that are
able to meet earnings expectations for the coming year will be 1998's best
performers.
 
HOW IS THE PORTFOLIO CURRENTLY STRUCTURED?
In our top down approach to managing the Portfolio we have focused on sectors
and industries that have little exposure to Asia's problems. In a more subdued
economy the companies that are able to consistently grow their revenues and
earnings in excess of the market will be best rewarded. Finally, we are
overweighted in financial stocks as we believe that the current interest rate
environment will remain in place and the group's overall earnings will continue
to grow.

                                    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.
 
BASIS POINT:  One hundredth of one percent in the yield of an investment, i.e.,
100 basis points equals 1%.
 
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.
 
CAPITALIZATION:  The amount of outstanding equity and debt a company has issued.
Companies may vary greatly in the amount of equity capital they have raised, and
their capitalization may change with new issues or stock repurchases.
 
CASH FLOW:  The amount of income or earnings available to cover outstanding
liabilities and other obligations, including debt service.
 
CORRECTION:  A market shift in security prices that brings them more in line
with historically appropriate levels.
 
CREDIT QUALITY:  A measure of an individual issuer's ability to repay principal
and interest on its income securities--or a measure of the general credit risk
of securities in an income portfolio.
 
CYCLICAL STOCK:  A 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.
 
DEFENSIVE ISSUES:  Stocks chosen for their reliability of earnings, growth, and
positive performance.
 
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.
 
FLIGHT TO QUALITY:  When investors in general move to improve the credit quality
of the securities they own, either because of credit concerns or a lack of yield
advantages among lower-rated securities.
 
HEDGING/CURRENCY MANAGEMENT:  The process of managing or "hedging" the risks
associated with owning securities denominated in different currencies, the
relative values of which may change at any time. There can be no assurance that
currency hedging will protect investors.
 
INFLATION:  An increase in the cost of goods and services over time. As prices
rise, the purchasing power of the dollar declines.
 
PREPAYMENT RISK:  The risk that mortgage or loan holders will repay their
obligations before they mature, shortening the stream of interest payments
investors receive.
 
SPLIT 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.
 
TIGHTEN/EASE:  When the Federal Reserve Board moves to raise interest rates it
is said to be "tightening" or making borrowing more expensive. When it moves to
lower rates, it is said to be "easing" or making borrowing more affordable.
 
TOTAL RETURN:  The performance of an investment with all income and capital
gains reinvested.
 
VOLATILITY:  Fluctuations in the price of securities or markets, up or down,
over a short period of time.
 
                                       12
<PAGE>   13
 
WEIGHTING:  The proportion of a portfolio allocated to a specific security or
sector, i.e., a portfolio is said to be overweighted in a sector when that
portion of the portfolio is greater than the sector's general relationship to
the market as a whole.
 
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.

NOTE 1-- Organization and Accounting Policies:
- --------------------------------------------------------------------------------

New York Life Insurance and Annuity Corporation MFA Separate Account I
("Separate Account I") and New York Life Insurance and Annuity Corporation MFA
Separate Account II ("Separate Account II") were established on May 27, 1983,
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 net premium payments under Qualified
Multi-Funded Retirement Annuity Policies ("Separate Account I") and
Non-Qualified Multi-Funded Retirement Annuity Policies ("Separate Account II")
issued by New York Life Insurance and Annuity Corporation.

  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 exclusively in shares of
the MainStay VP Series Fund, Inc. (formerly, "New York Life MFA Series Fund,
Inc."), a diversified open-end management investment company, and are clearly
identified and distinguished from the other assets and liabilities of New York
Life Insurance and Annuity Corporation. Effective December 19, 1994, sales of
all such Policies were discontinued.

  There are six Investment Divisions within both Separate Account I and Separate
Account II, three of which invest Single Premium Policy net premium payments and
three of which invest Flexible Premium Policy net premium payments. The Common
Stock Investment Divisions invest in the Growth Equity Portfolio, the Bond
Investment Divisions invest in the Bond Portfolio, and the Money Market
Investment Divisions invest in the Cash Management Portfolio. Net premium
payments received are allocated to the Investment Divisions of Separate Account
I or Separate Account II according to Policyowner instructions. In addition, the
Policyowner has the option to transfer amounts between the Investment Divisions
of Separate Account I and 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 investment in the MainStay VP Series Fund, Inc. is
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.

  Annuity Reserves--The reserves are computed for currently payable contracts in
accordance with rates taken from approved valuation mortality tables. The
assumed interest rate is 4%, unless issued in Florida or Texas where the rate is
3 1/2%. Separate Account II Common Stock Investment Division for Single Premium
Policies had variable annuity unit values as of December 31, 1997 and December
31, 1996 of $2.90 and $2.41, respectively.

  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 for Flexible Premium Policies, and Single and Flexible Premium
Policies are charged for the mortality and expense risks assumed by New York
Life Insurance and Annuity Corporation. These charges are made daily at an
annual rate of 1.25% of the daily net asset value for Single Premium Policies
and 1.75% of the daily net asset value for Flexible Premium Policies 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.

REPORT OF INDEPENDENT ACCOUNTANTS
- --------------------------------------------------------------------------------

To the Board of Directors of New York Life Insurance and
Annuity Corporation and the MFA Policyowners:
 
In our opinion, the accompanying statement of assets and liabilities and the
related statements of operations, of changes in total equity and the selected
per unit data present fairly, in all material respects, the financial position
of the New York Life Insurance and Annuity Corporation MFA Separate Account I
and New York Life Insurance and Annuity Corporation MFA Separate Account II,
comprised of the Single and Flexible Premium Policies Common Stock Investment
Divisions, the Single and Flexible Premium Policies Bond Investment Divisions
and the Single and Flexible Premium Policies Money Market Investment Divisions
at December 31, 1997, and the results of each of their operations, the changes
in each of their total equity, and the selected per unit data for each of the
periods presented in conformity with generally accepted accounting principles.
These financial statements and the selected per unit data (herein referred to as
the "financial statements") are the responsibility of management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these financial statements in accordance
with generally accepted auditing standards which require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audits, which included confirmation of investments at
December 31, 1997 with the MainStay VP Series Fund, Inc., provide a reasonable
basis for the opinion expressed above.

NOTES TO FINANCIAL STATEMENTS
 
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. Cash Management Portfolio, 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 MFA Separate Account I, MFA Separate
Account II and VLI Separate Account (collectively "Separate Accounts"). The MFA
Separate Accounts are used to fund multi-funded retirement annuity policies and
the VLI Separate Account is used to fund variable life insurance policies
issued by NYLIAC.
 
The investment objectives for each of the Portfolios of the Company are as
follows:
 
Cash Management:  to seek as high a level of current income as is considered
consistent with the preservation of capital and liquidity.
 
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.
 
- --------------------------------------------------------------------------------
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
 
                                       46
<PAGE>   47
                                                   MAINSTAY VP SERIES FUND, INC.


 
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)
 
REPURCHASE AGREEMENTS. At the time a Portfolio enters into a repurchase
agreement, the value of the underlying security, including accrued interest,
will be equal to or exceed the value of the repurchase agreement and, in the
case of repurchase agreements exceeding one day, the value of the underlying
security, including accrued interest, is required during the term of the
agreement to be equal to or exceed the value of the repurchase agreement. The
underlying securities for all repurchase agreements are held in a segregated
account of the respective Portfolio's custodian. In the case of repurchase
agreements exceeding one day, the market value of the underlying securities are
monitored by the Adviser by pricing them daily. (Also see Note 5).
 
                                      (D)
 
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.
 
                                      (E)
 
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.

The reclassifications for the Portfolios relate primarily to the character for
tax purposes of certain short-term gains and losses.
 
                                      (G)
 
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.
 
                                      (H)
 
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.
 
                                      (I)
 
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.

REPORT OF INDEPENDENT ACCOUNTANTS
- --------------------------------------------------------------------------------

To the Board of Directors and Shareholders of
MainStay VP Series Fund, Inc.
 
In our opinion, the accompanying statements of assets and liabilities, including
the portfolios of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of Cash Management Portfolio, Bond
Portfolio and Growth Equity Portfolio (three of the eleven portfolios
constituting MainStay VP Series Fund, Inc., hereafter referred to as the "Fund")
at December 31, 1997, and the results of each of their operations for the year
then ended, the changes in each of their net assets for each of the periods
indicated and the financial highlights for each of the periods indicated, in
conformity with generally accepted accounting principles. These financial
statements and financial highlights (hereafter referred to as "financial
statements") are the responsibility of the Fund's management; our responsibility
is to express an opinion on these financial statements based on our audits. We
conducted our audits of these financial statements in accordance with generally
accepted auditing standards which require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements, assessing
the accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits, which included confirmation of securities at December 31, 1997 by
correspondence with the custodians and brokers and the application of
alternative auditing procedures where confirmations from brokers were not
received, provide a reasonable basis for the opinion expressed above.
