*   Performance figures for the Service Class, first offered to the public on
    1/1/95, include the historical performance of the Institutional Class from
    the Funds' inception (1/2/91) up to December 31, 1994. Performance figures
    for these two Classes after this date will vary based on differences in
    their expense structures.

+   The inception date of these Institutional Class shares and the date such
    shares were first offered to the public is 1/2/91.

(S) The inception date of the International Equity Fund and International Bond
    Fund shares and the date such shares were first offered to the public is
    1/1/95.

**  The total return reflects the annual return on an investment including
    appreciation and dividends or interest. Total returns shown herein include
    the change in share price and reinvestment of capital gains distributions
    and dividends, and, for the Service Class shares, include the service fee 
    of .25%.

++  The Money Market Fund-Institutional Class had an effective 7-day yield of
    5.16% with an average 7-day yield of 5.04%, both as of 12/31/96. The Money
    Market Fund-Service Class had an effective 7-day yield of 4.91% with an
    average 7-day yield of 4.79%, both as of 12/31/96. The Administrator has
    agreed to assume a portion of the expenses for this Fund. Had certain
    expenses not been assumed by the Administrator, the effective 7-day yield
    and the average 7-day yield would have been 5.02% and 4.90%, respectively,
    for the Institutional Class and 4.76% and 4.65%, respectively, for the
    Service Class.

    Investments in the Money Market Fund are neither insured nor guaranteed by
    the U.S. Government, and there is no assurance that the Fund will be able to
    maintain a stable net asset value of $1.00 per share.

    Past performance is no guarantee of future results. Investment return and
    principal value will fluctuate so that upon redemption, shares may be worth
    more or less than their original cost.

    Performance figures for each Fund reflect the waiver (through 1993 for the
    Value Equity Fund and Growth Equity Fund) of a portion of New York Life
    Insurance Company's fees (up to the amount of such fees), received as
    Administrator for each Fund, to the extent necessary to limit the total
    operating expenses of such Funds. As a result, total return figures, which
    take into account this fee waiver, would have been lower had New York Life
    not waived its administrative fees.

    The Funds currently offer two Classes of shares. Investors should consider,
    when deciding whether to purchase a particular Class of shares, the services
    desired and other relevant factors.

    See prospectus for more detailed information. The Funds' prospectus contains
    more information about advisory fees, other expenses and share classes.
    Please read it carefully before you invest or send money.

    The Institutional Class shares are sold with no sales charge. The Service
    Class shares, first offered 1/1/95, are sold with no initial or contingent
    deferred sales charge, but are subject to an annual shareholder service fee
    of .25%.

    Foreign investing may be subject to greater risks than domestic investing.
    These may include securities markets that are less efficient, less liquid
    and more volatile than those in the United States, as well as foreign
    currency fluctuations and different governmental regulatory concerns.

CHAIRPERSON'S LETTER
================================================================================

REPORT TO SHAREHOLDERS FOR THE FISCAL YEAR ENDED DECEMBER 31, 1996

The undisputed story of 1996 was the remarkable momentum of the equity market.
The bond market took a back seat while the financial community and investors
watched the U.S. stock market soar by 23%.* The Dow Jones Industrial Average
broke 6,600. Exciting new companies entered the markets and received
overwhelming public support. New trends--the Internet, for one--gave rise to new
waves of optimism. Assets in mutual funds surpassed all the gold in both Fort
Knox and the New York Federal Reserve combined.

[PHOTO OF ALICE T. KANE, CHAIRPERSON APPEARS HERE]

Strong performance is important, but we shouldn't lose sight of what must be
consistent in any investment climate: the philosophy, the strategies, the work
ethic, the education, and the communication between a mutual fund company and
its investors. It shouldn't be assumed that the market will continue at this
pace--even though past successes will cause some to think it will. It is
important to remember that mutual fund investing isn't about timing markets,
it's about setting realistic goals and plotting a long term course to help you
get there.

That's where MainStay(R) comes in. It's a name that stands for working to stay
the course no matter what the conditions. We know you depend on us to remain
steadfast in our vigilance, to do the research, make prudent choices, and
provide timely, accurate, and useful information. However, staying steady
doesn't mean standing pat. So we continue to work at creating simplicity, and
going beyond providing information, to providing understanding. For example, our
simplified prospectus is unlike any other in the industry, and we've been
complimented in the press for our series of educational brochures, such as
Navigating through the Star Ratings and What Is The S&P 500 ... And What Can It
Tell Me About My Investments?

We at MainStay have a responsibility to help you, our investors, stay informed
and to be in a position to make intelligent decisions.  One way we are doing
this is through the comprehensive Internet site that we launched on the World
Wide Web in November of 1996.  Our goal is to make fund and investment
information available to you 24 hours a day, 7 days a week.  The site features
extensive information about all of our Funds, daily net asset values and easy-
to-read material on retirement plan investing.  Our Internet address is:
http://www.mainstayfunds.com.  Visit us often, and e-mail us from any page in
the site with your questions, comments and requests.

No one can promise 1997 will be a repeat of 1996 because the market is ever-
changing. But we at MainStay can promise to continue managing funds to seek
downside protection as well as upside performance. We'll be with you to help
stay the course toward your investment horizons.

Wishing you all the best,

/s/ Alice T. Kane

PORTFOLIO MANAGERS' INTERVIEWS & COMMENTS


EAFE INDEX FUND
================================================================================

- --------------------------------------------------------------------------------
1996 MARKET HIGHLIGHTS
- --------------------------------------------------------------------------------
 .  Many stock markets around the globe provided double-digit returns for the 12
    months ended 12/31/96, with several markets outperforming the S&P 500 Stock
    Index+ return of 22.94%
 
 .  Japan, the world's second largest equity market, declined 4.92% in local
    terms and was down a full 15.50% when the results were translated into
    dollars
 
 .  Outstanding returns were recorded in Spain, Sweden, Finland, Norway, and
    the U.K.

- --------------------------------------------------------------------------------
1996 FUND HIGHLIGHTS
- --------------------------------------------------------------------------------
 .  For the year ended 12/31/96, the MainStay Institutional EAFE Index Fund
    returned 6.45% and 6.37% for Institutional Class shares and Service Class
    shares, respectively
 
 .  Throughout the year, the Fund closely tracked its benchmark, the Morgan
    Stanley Capital International (MSCI) Europe, Far East, Australia (EAFE)
    Index(S)

- --------------------------------------------------------------------------------
Inflation   An increase in the cost of goods and services over time.
Bourse The French term for stock exchange is sometimes used as a general term to
refer to European stock exchanges in general.

Weighting   The proportion of a portfolio allocated to a specific market sector 
or country, i.e., a fund is said to be overweighted in a country when that
portion of the portfolio is larger than the country's securities are to the
market or index as a whole.

Bullish/Bearish   A bull market occurs when stock prices are rising, a bear
market occurs when stock 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.
- --------------------------------------------------------------------------------

In 1996, many of the world's stock markets provided outstanding returns.
Strengthening economies across Europe combined with low inflation to push prices
on local bourses higher. While several European countries even outperformed the
22.94% return of the S&P 500 Stock Index, Japanese stocks had a severely
negative impact on the Morgan Stanley Capital International EAFE Index for the
year.

With the yen falling relative to the dollar, the earnings outlook for many
export-oriented Japanese companies looked good in the first half, as Japanese
stock prices rose 7.53% in local terms. But when expected economic improvements
in Japan failed to materialize and its banking sector suffered major setbacks,
Japanese stocks ended the year down 4.92% in local terms. Unfortunately for
American investors, however, the weak yen resulted in a 15.50% loss, when
translated into U.S. dollars.

European stock markets did considerably better. Spain was up 40.05%, Finland
gained 33.94%, Norway advanced 28.63%, Sweden rose 37.21%, and the U.K. was up
27.42% (all translated into U.S. dollars) for the year. These strong results
boosted the return on the MSCI EAFE Index to 6.05% for the 12 months ended
12/31/96.

================================================================================

Given this context, how did the MainStay Institutional EAFE Index Fund do?

For the 12 months ended 12/31/96, the MainStay Institutional EAFE Index Fund
returned 6.45% and 6.37% for Institutional Class shares and Service Class
shares, respectively. Both share classes slightly outperformed their benchmark
Index, but underperformed the average Lipper* international fund, which returned
11.78% over the same period.

Why was there such a gap between the Fund and its Lipper peers?

The Fund seeks to track the makeup and performance of the EAFE Index, which is
heavily weighted in Japanese stocks. Since the Fund's weightings are determined
by those of the Index, we did not have the option of reducing our exposure to
Japanese equities, as many strategically managed international funds did during
the year. While heavy participation in any declining market will be negative for
the portfolio as a whole, the Fund is also designed to participate heavily in
the Japanese market in any year in which it may rise, which may have a positive
effect on performance.

Which markets receive the heaviest weightings in the EAFE Index?

Japan is the world's second largest stock market and the largest market in the
Index, accounting for 31.9% of its investments. The United Kingdom represents
the largest European market, accounting for 18.6% of the Index, and contributed
significantly to the Fund's positive performance. While Spain and the
Scandinavian markets had excellent returns, their individual weightings in the
portfolio are smaller, which affected the significance of their impact on
overall performance.

Why did Japanese stocks do so poorly?

Although Japan was well positioned for an economic recovery, investors were
generally bearish on the market, perhaps waiting for additional signs that
investments there will be rewarded. The banking sector was severely battered in
1996, suffering the effects of bad loans made in previous years, which helped
bring Japanese stocks into negative territory. Unfortunately, the negative
returns were compounded by unfavorable currency relationships. When the dollar
is strong and the yen is weak, international investors may experience additional
losses when returns in a weak currency are translated into U.S. dollars.

What's your outlook for 1997?

We remain optimistic and continue to believe that international equities
represent a sound way for investors to diversify their portfolios as they pursue
higher return potential.

**  Performance figures for the Service Class, first offered to the public on
    1/1/95, include the historical performance of the Institutional Class from
    the Fund's inception (1/2/91) up to December 31, 1994. Performance figures
    for these two Classes after this date will vary based on differences in
    their expense structures.

*   The total return reflects the annual return on an investment including
    appreciation and dividends or interest. Total returns shown herein include
    the change in share price and reinvestment of capital gains distributions
    and dividends, and, for the Service Class shares, include the service fee of
    .25%.

    Past performance is no guarantee of future results. Investment return and
    principal value will fluctuate so that upon redemption, shares may be worth
    more or less than their original cost.

    The Institutional Class shares are sold with no sales charge. The Service
    Class shares, first offered 1/1/95, are sold with no initial or contingent
    deferred sales charge, but are subject to an annual shareholder service fee
    of .25%.

    Unlike other funds which generally seek to "beat" the market, index funds
    seek to "match" their respective indices.

GROWTH EQUITY FUND
================================================================================

- --------------------------------------------------------------------------------
1996 MARKET HIGHLIGHTS
- --------------------------------------------------------------------------------
 .  Despite unusual volatility, the stock market had a strong year in 1996, with
    the S&P 500 Stock Index+ rising 22.94%

 .  Throughout the year, investors focused on interest rates, inflation, and the
    possibility of Federal Reserve action

 .  Stocks declined sharply in June and July, but recovered through the second
    half of the year

 .  While growth stocks did well through the first nine months of the year,
    value stocks were stronger in the fourth quarter

 .  Most of the stock market's gains were concentrated in a small number of
    stocks

- --------------------------------------------------------------------------------
1996 FUND HIGHLIGHTS
- --------------------------------------------------------------------------------
 .  One-year total returns of 21.62% and 21.29% for Institutional Class and
    Service Class shares, respectively, as of 12/31/96

 .  Both share classes outperformed the average Lipper* growth fund, which
    returned 19.24% for the 12 months ended 12/31/96

 .  The Fund's financial, technology, and energy stocks contributed positively
    to performance

 .  Health care stocks tended to underperform, as did certain media issues which
    were sold in the second and third quarters

- --------------------------------------------------------------------------------
Inflation  An increase in the cost of goods and services over time. As prices
rise, the purchasing power of the dollar declines.

Capitalization  The amount of outstanding equity 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.
- --------------------------------------------------------------------------------


Growth stocks had another outstanding year in 1996, with the S&P 500 Stock Index
returning 22.94% -- more than twice the average annual total return for the
previous 70 years.(S) Unlike 1995, however, the gains were mostly concentrated
in a small number of issues. Throughout the year, investors tried to anticipate
the Federal Reserve's interest rate moves, carefully watched for signs of
impending inflation, and reacted quickly and decisively to negative earnings
reports.

A sharp decline in small capitalization stocks in May was followed by a broader
correction in June and July, making stocks much more volatile than in recent
years. While the market recovered strongly in the second half, by the fourth
quarter, investors had shifted their focus from growth equities to value stocks.

For the entire year, the leading industries were energy, banks, and technology,
including semiconductors, computers, and software. Footwear companies stepped
ahead of the market, while trucking, steel, and factory equipment lagged the
market. Media and health care generally underperformed the market. In general,
stock performance was strengthened by huge cash inflows into equity mutual
funds. Despite heavy volatility and variable results in different industries,
for the 12 months ended 12/31/96, the average Lipper growth fund returned
19.24%.

================================================================================

- --------------------------------------------------------------------------------
Bottom-up investing Security selection based on the specific 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.

Weighting The proportion of a portfolio allocated to a specific security or
sector, i.e., a fund 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.
- --------------------------------------------------------------------------------

Given this context, how did the MainStay Institutional Growth Equity Fund do in
1996?

The Fund performed very well. For the year ended December 31, 1996, the MainStay
Institutional Growth Equity Fund returned 21.62% and 21.29% for Institutional
Class and Service Class shares, respectively. Both classes of shares
outperformed the average Lipper growth fund.

How did the Fund manage to do so well?

The Fund uses a bottom-up investment approach, evaluating each stock on its
individual merits. When the portfolio managers see fundamental value and strong
growth characteristics, the Fund may be rewarded, even when it takes the Fund in
a different direction than other growth managers. For example, in 1996, the Fund
was overweighted in financial stocks all year long. Many growth managers didn't
invest in financial issues, but we felt some had potential for bottom line
growth in excess of 20%. We weren't betting on where interest rates were headed.
We felt that we'd found stocks that could perform well because of their inherent
strengths. As it happened, the Federal Reserve didn't make any major moves
during the year, and financial stocks did very well.

Can you be more specific?

Certainly. Green Tree Financial is a leading financier of manufactured housing,
small aircraft purchases, and has moved into the home improvement business.
Their bottom line was growing quickly and the stock was trading at an attractive
price for its earnings potential. We held the stock all year, and even though it
had some ups and downs, overall it returned 53% for the portfolio.**

Were there other attractive financial stocks?

Yes, there were. SunAmerica is an annuity company that did particularly well in
the fourth quarter. For the year, it was up 89%, and it had the greatest
positive impact of any stock in the Fund's portfolio. First U.S.A. is one of the
nation's biggest credit card companies, and Traveler's is a diversified
financial company with Smith Barney, a subsidiary, as a star performer. Both of
these stocks performed very well during the year. Unfortunately, we had some
disappointment in the financial sector. In the second quarter, we reduced our
exposure to financial services stocks and sold Bank of New York and Barnett
Bank, both of which rose to all-time highs after we cut our positions. While we
sold at a profit, we missed some opportunities there.

What other stocks did you sell during the year?

Moving into the second and third quarters, we sold several of our media stocks,
including News Corp. and Tele-Communications International. We saw their
earnings estimates were coming down and felt their fundamentals were
deteriorating. The decision turned out to be a wise one, since these stocks have
generally underperformed the market. In the third quarter, we also sold two
airline stocks -- Southwest and Atlantic Southeast. Again, we were convinced
that their fundamentals were weakening and our decision paid off. While they've
recovered a bit from where we sold them, on a relative basis, they've both
underperformed the market.

What did you buy during the year?

One of our most important purchases was Nike, which we bought in the first
quarter. The company sells shoes and sportswear, and its fundamentals have
continued to improve. The company profited from the Olympic games, and now their
future orders are very strong. Over the course of the year, the stock returned
79% for the Fund. Another stock we bought in the first quarter was Safeway, a
leading supermarket chain that showed strong growth characteristics, based on
our proprietary evaluation techniques. Safeway returned 62% for the Fund in
1996.

- --------------------------------------------------------------------------------
** Returns reflect performance during the period securities were held in the
   Fund.

================================================================================

Are there other holdings that performed well?

We did well with Tyco International, a diversified company that manufactures
everything from sprinklers and fire hydrants to bandages and fiber optics. We
liked their rate of earnings growth, which has continued to improve. For the
year, the stock gained 78%. HFS is a company we bought in 1995. They're a
leading hotel franchiser, with interests in real estate, condominium time
shares, and rental cars. They were up 63% for the year and we expect outstanding
earnings growth in 1997. We also owned Cisco Systems, a large networking
company, based on its strong fundamentals and earnings potential. Later in the
year, as the market moved toward larger, more seasoned names, such as Microsoft
and Intel, Cisco Systems also advanced, bringing a 29% gain to the Fund.

What about the Fund's other technology stocks?

Technology stocks were highly volatile in 1996, particularly during June and
July. But many advanced over the course of the year. Intel was up 131% for the
year, performing particularly well, especially during the fourth quarter.
Another networking company, 3Com, was up 58%. Computer Associates did well for
the year, despite some negative news on European earnings in the fourth quarter.
Other technology stocks were considerably weaker. We sold Micron Technology and
Motorola in the first quarter because they faced severe pricing pressure,
despite strong sales. The Micron sale helped the portfolio, since the stock has
underperformed. While Motorola has come back a bit, we view our decision to sell
as positive in reducing portfolio volatility. Lam Research, another
semiconductor company, was a major disappointment, down 39% for the year.

What happened to the Fund's health care stock holdings in 1996?

When it became clear that President Clinton was likely to win the re-election,
health care issues started to decline. The most severely hurt sector was HMOs,
which suffered because of higher medical costs, greater utilization, and slow
premium growth. When United Healthcare preannounced poor second quarter
performance, the Fund suffered. Even though United Healthcare and Humana were
both down 31% for the year, we've continued to hold the stocks, because we
believe they have long-term potential. Early in the year, we sold Mylan Labs,
the leading name in generic drugs. While generic drugs are growing in
popularity, competitive pressures have undermined their pricing edge. Since the
stock was down 40% in 1996, we believe the sale was a wise decision.

Are there other medical stocks that did well?

Johnson & Johnson and Schering-Plough both provided positive performance for the
Fund. Medtronic, the world's largest medical implant manufacturer, and Guidant,
a company in a related business had excellent results. Guidant has grown about
20% over the year and has developed a new product for cardiac surgery that may
have the potential to substantially increase their sales in the future.

Speaking of the future, what's your outlook for 1997?

At the end of the year we were overweighted in financials and large
capitalization technology issues. We're continuing to evaluate the fundamental
prospects in the health care sector, with a focus on HMOs. While Nike was an
exception, most consumer stocks did poorly in the fourth quarter. We're looking
for ways to improve performance in the near term while seeking companies that
will do well over the long haul. As always, we'll continue to look for
opportunities and evaluate risks, seeking long-term capital growth for our
shareholders.

**  Performance figures for the Service Class, first offered to the public on
    1/1/95, include the historical performance of the Institutional Class from
    the Fund's inception (1/2/91) up to December 31, 1994. Performance figures
    for these two Classes after this date will vary based on differences in
    their expense structures.

*   The total return reflects the annual return on an investment including
    appreciation and dividends or interest. Total returns shown herein include
    the change in share price and reinvestment of capital gains distributions
    and dividends, and, for the Service Class shares, include the service fee of
    .25%.

    Past performance is no guarantee of future results. Investment return and
    principal value will fluctuate so that upon redemption, shares may be worth
    more or less than their original cost.

    The Institutional Class shares are sold with no sales charge. The Service
    Class shares, first offered 1/1/95, are sold with no initial or contingent
    deferred sales charge, but are subject to an annual shareholder service fee
    of .25%.

 .  The year was an outstanding one for stocks, particularly large
    capitalization issues

 .  The Dow Jones Industrial Average recorded a 28.91% gain for the year

 .  Top performing sectors included Oil & Gas Drilling, Shoes, and Electronic
    Semiconductors

 .  Worst performing sectors included Truckers, Broadcast/Media and Machines

- --------------------------------------------------------------------------------
1996 FUND HIGHLIGHTS
- --------------------------------------------------------------------------------
 .  One-year total returns of 22.57% and 22.21% for Institutional Class and
    Service Class shares, respectively, as of 12/31/96

 .  Best one-year performance of all MainStay Institutional Funds as of 12/31/96

 .  Institutional Class shares received a four-star overall rating from
    Morningstar, Inc.++ , as of 12/31/96

- --------------------------------------------------------------------------------
Total return   The performance of an investment with all income and capital
gains reinvested.

Capitalization   The amount of outstanding equity 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.

Bull market/bear market   A bull market is a period of rising prices, and a bear
market is a period of falling prices.

Inflation   An increase in the cost of goods and services over time. As prices
rise, the purchasing power of the dollar declines.
- --------------------------------------------------------------------------------


To the surprise and delight of equity investors, 1996 was another stellar year
for stocks. While this year's results didn't match the Fund's 37% return earned
in 1995, it would be hard to be disappointed with the S&P 500 Stock Index's
return of 22.94% for the 12 months ended 12/31/96, which was more than twice the
average annual total return of the Index over the previous 70 years.(S)

Large capitalization stocks led the way, with the Dow Jones Industrial Average
increasing 28.91% for the year. For the year ended 12/31/96, the average Lipper
S&P 500 Index fund* returned 22.30%.

Given this context, how did the MainStay Institutional Indexed Equity Fund do in
1996?

For the 12 months ended 12/31/96, the MainStay Institutional Indexed Equity Fund
returned 22.57% and 22.21% for Institutional Class shares and Service Class
shares, respectively. The Institutional Class shares outperformed the average
Lipper S&P 500 Index fund for the same period, and both classes

++   Morningstar, Inc. is an independent fund performance monitor. Its ratings
     reflect risk-adjusted performance, which does not include sales charges,
     and may change monthly. Its ratings of 1 (low) and 5 (high) stars are based
     on a fund's 3-, 5- & 10-year average annual returns with fee adjustments,
     and a risk factor that reflects fund performance relative to 3-month
     Treasury bill monthly returns. A one-year rating is calculated using the
     same methodology, but is not a component of the overall rating. As of
     12/31/96, the individual 1, 3 and 5 year ratings for the MainStay
     Institutional Indexed Equity Fund was 4, 5 and 4 stars, respectively. For
     the one-year period, the Fund was rated among 2,959 funds in the domestic
     equity category. Only 10% of the funds in an investment category may
     receive 5 stars and 22.5% may receive 4 stars. Ratings reflect
     Institutional Class performance only. Service Class shares, first
     introduced January 1, 1995, will not be rated by Morningstar until they
     have a three year operating history.

of shares outperformed the average Lipper U.S. stock fund, which returned 19.47%
for the year.

This performance helped the Fund's Institutional Class shares earn a four-star
overall rating from Morningstar, placing them among the top 33% of their
Morningstar universe, which consisted of 1,826 domestic equity funds for the 
3-year period and 1,058 domestic equity funds for the 5-year period ending
12/31/96.

Which stocks did best in 1996?

The S&P 500 Stock Index is composed primarily of large capitalization stocks,
many of which did exceedingly well in 1996. Among the strongest performing
stocks for the year were Rowan Co., up 135.1%, Nike, up 73.5%, and Intel, up
131.3% in their respective industry sectors; Oil & Gas Drilling, up 103.9%,
Shoes up 65.0%, and Electronic Semiconductors, up 56.9%.

Were these sectors equally weighted in the Fund's portfolio?

No. Each sector is individually weighted in the S&P 500 by its perceived
importance in the economy. Because of this, Oil & Gas Drilling, Shoes, and
Electronic Semiconductors represented 0.06%, 0.36%, and 3.27%, respectively of
the Index. So each made a different level of contribution to the overall
performance of the Index and the Fund.

Which sectors were the worst performers?

Truckers was the weakest sector in 1996, but represented only 0.01% of the
Index. Broadcast/Media and Machines were also laggards, representing 0.47% and
0.02% of the Index, respectively.

Why didn't the Fund outperform the Index?

Unlike an index, the returns of which are based on hypothetical investments, the
Fund is a real-world investment and incurs trading expenses and management fees.
As a result, the Fund cannot fully replicate the performance of the Index, and
will usually trail it by at least a small margin. Investors should take this
into account in evaluating the performance of any indexed fund.

How does the Fund seek to track the Index?

The Fund seeks to remain as fully invested as possible at all times, attempting
to mirror the performance of the Index by investing in all 500 stocks in the
same proportion as they are represented in the Index. Doing so allows the Fund
to participate as fully as possible in bull markets, like the one we had this
year. On the other hand, this policy will also cause the Fund to participate as
fully as possible in declines during bear markets.

Does indexing offer any advantages over other forms of investing?

While past performance is no guarantee of future results, over the five years
ended 12/31/96, the average annual total return of the average Lipper U.S. stock
fund was 13.65%, compared to 14.71% for the average Lipper S&P 500 Index Fund.
For the 10-year period ended 12/31/96, the numbers are 13.29% and 14.43%,
respectively. While the Indexed Equity Fund's returns may be higher or lower
than the S&P 500 and the Lipper averages over any given period, these figures
suggest that indexing may be an appropriate strategy for inflation-conscious
investors seeking higher equity returns over the long-term.

**   Performance figures for the Service Class, first offered to the public on
     1/1/95, include the historical performance of the Institutional Class from
     the Fund's inception (1/2/91) up to December 31, 1994. Performance figures
     for these two Classes after this date will vary based on differences in
     their expense structures.

*    The total return reflects the annual return on an investment including
     appreciation and dividends or interest. Total returns shown herein include
     the change in share price and reinvestment of capital gains distributions
     and dividends, and, for the Service Class shares, include the service fee
     of .25%.

     Past performance is no guarantee of future results. Investment return and
     principal value will fluctuate so that upon redemption, shares may be worth
     more or less than their original cost.

     The Institutional Class shares are sold with no sales charge. The Service
     Class shares, first offered 1/1/95, are sold with no initial or contingent
     deferred sales charge, but are subject to an annual shareholder service fee
     of .25%.

     Unlike other funds which generally seek to "beat" the market, index funds
     seek to "match" their respective indices.

INTERNATIONAL EQUITY FUND
================================================================================

- --------------------------------------------------------------------------------
1996 MARKET HIGHLIGHTS
- --------------------------------------------------------------------------------
 .  International equity markets generally experienced positive performance,
    with the Morgan Stanley Capital International EAFE Index(S) returning 6.05%
    for the 12 months ended December 31, 1996

 .  An accommodative interest rate environment worldwide was good for
    international corporate growth, and particularly good for interest rate
    sensitive stocks

 .  While Japan showed improving fundamentals, the Japanese stock market
    provided the worst returns of any major world market, losing 4.92% for the
    year

 .  Spain, Norway, Sweden, Finland and the Netherlands markets provided
    excellent overall performance, with Italy, France, Germany, and Hong Kong
    also providing positive returns

 .  A market reversal in June and July, led by declines in U.S. equities, left
    many international returns in the second half of the year at more modest
    levels

- --------------------------------------------------------------------------------
1996 FUND HIGHLIGHTS
- --------------------------------------------------------------------------------
 .  One-year total returns of 12.09% and 11.59% for Institutional Class and
    Service Class shares, respectively, as of 12/31/96

 .  The Fund outpaced the Morgan Stanley Capital International EAFE Index for
    the 12 months ended 12/31/96

 .  The Fund performed closely with the average Lipper* international equity
    fund for the 12 months ended 12/31/96

 .  The portfolio benefited from investments in Spain and Italy, and energy
    investments in Norway and the Netherlands, but was hurt by large holdings in
    Japan

 .  Selective currency hedging helped work to the advantage of investors in the
    Fund throughout the year

- --------------------------------------------------------------------------------
Accomodative interest rates   When countries maintain low interest rates that
allow businesses to borrow at lower cost, they are said to be "accommodating"
business in this regard. Low interest rates tend to allow companies to raise
more affordable capital for expansion, and may stimulate corporate and economic
growth.
- --------------------------------------------------------------------------------

Throughout 1996, the international equity markets benefited from accommodative
interest rate policies in most major markets around the world. The low interest
rate environment helped act as a stimulus for corporate growth and had a
positive impact on interest rate sensitive industries such as banking and
finance. The strengthening of economic fundamentals also led to gains in energy
stocks, which benefited from greater demand for fuel around the world.

In Europe, massive restructuring has begun, offering potential opportunities for
companies to increase their profitability and reduce their labor costs. A new
law recently passed in Germany will allow employers to substantially reduce
their benefit costs, which could improve corporate earnings prospects there. In
France, corporate profit growth continues to be promising due to the lack of
wage cost increases caused by high unemployment rates and generally lower

Restructuring   Any action designed to improve the overall financial structure,
labor relations, or productivity of a company. Restructuring may include such
steps as changing management, investing in new plants and equipment, engaging in
mergers and acquisitions, or taking other action to increase output or lower
costs.

Bullish/Bearish   A bull market occurs when stock prices are rising, a bear
market occurs when stock 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.

Weighting   The proportion of a portfolio allocated to a specific market sector
or country, i.e., a fund is said to be overweighted in a country when that
portion of the portfolio is larger than the country's securities are to the
market as a whole.

Currency management/hedging   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 be beneficial to investors.

production costs. All of this may be good for industry in France and Germany and
may bode well for the future of European industry.

Although Asian markets faltered in July when the U.S. technology industry had a
severe setback, later in the year, the situation stabilized and growth trends
are once again emerging. Japan appears as a notable exception. Despite improving
economic fundamentals, investors have remained bearish, resulting in an overall
market decline of about 5% for the year. While some Japanese banks closed during
the year, others did relatively well. Autos were good performers within the weak
Japanese market. But retailers were hurt by low returns on savings and reduced
consumer confidence.

How did the MainStay Institutional International Equity Fund perform in this
context?

For the 12 months ended December 31, 1996, the MainStay Institutional
International Equity Fund had total returns of 12.09% and 11.59% for
Institutional Class shares and Service Class shares, respectively. These results
closely followed the average Lipper international fund, which returned 11.78%
for the same period, but were well ahead of the Morgan Stanley Capital
International EAFE Index, which returned only 6.05%.

What were the Fund's strongest investments during the year?

The Fund uses a country-first approach, seeking out the most promising markets
and then investing in a wide range of companies in the markets the portfolio
manager feels have positive prospects. In 1996, the Fund saw strong returns in
Spain and Italy (up 50.16% and 7.81%, respectively in local terms), the
Netherlands (+37.59% in local terms) and Norway (+30.00% in local terms), where
we concentrated in oil and energy-related issues. The Fund also did well in
France, where interest rates had a positive impact on agriculture-related
businesses that feed most of Europe.

What can those successes be attributed to?

We believe strategy was ultimately responsible. The Fund has held energy-related
positions in the Netherlands and Norway for some time, and recognized that the
improving economic fundamentals would increase demand for fuels. Oil prices
started the year at about $16 per barrel and ended around $23 per barrel, and
the rising prices were good for the Fund. In Spain, the Fund's holdings
increased among utilities and banks, which profited from the accommodative
interest rate environment. All of these positions have made positive
contributions to the Fund throughout the year.

Were there any major market opportunities that were missed?

The Fund wasn't invested in Sweden, which was up 41.36% (in local terms) for the
year--or Finland, which was up 42.18% (local terms). Given how these markets had
performed in 1995, the portfolio manager felt they were fully valued. Their
growth was surprising and some opportunities in these markets were missed.

What about the Far East?

The big story in the Far East was Japan. All the fundamentals seemed in place
for a market improvement. Interest rates were low and the environment was
friendly for business. However, investors remained bearish all year. Since Japan
was the weakest major market, down 4.92% in 1996, the Fund's large position
there definitely hurt perfor-

mance. There were, however, some redeeming factors. While some Japanese banks
closed during the year, the Fund was invested in stronger banks that survived
the crisis. The Fund also held auto stocks which did well on a relative basis.
In the fourth quarter, as it appeared that the market was not going to respond
to positive fundamentals, the Fund reduced its weighting in Japan, which was
already lower than the overall weighting in the EAFE index. This helped the
Fund's portfolio control risk and avoid some losses. If conditions remain the
same, we intend to continue moving away from Japan, waiting for investor
sentiment to turn more positive.

What were the Fund's other investments in the Far East?

In Hong Kong, the Fund increased its holdings in the second half of the year
when we saw opportunities to profit from this gateway for Chinese exports. The
result was positive for the Fund. Singapore, which is a major exporter of
electronic components and computer products, faced a downturn in midyear, when
U.S. technology stocks faltered. While that had a negative impact on Fund
performance, the Fund continued to hold its Singapore equities, such as
Singapore Telecommunications, Ltd. and Oversea-Chinese Banking Corp., Ltd.,
which represent a relatively small portion of the Fund's holdings. In the fourth
quarter, orders began to flow back to Singapore, so the downturn appears to be
reversing. We're pleased that this decision to hold these securities had
positive results and look forward to improved prospects in 1997.

How has the Fund's portfolio responded to restructuring in Europe?

Restructuring can be a positive factor for virtually any economy. We see it as a
positive force that could improve balance sheets, enhance productivity, and
lower labor costs through outsourcing production to Eastern Europe and Asia. By
adding to the Fund's holdings in Germany and the Netherlands in the fourth
quarter, the Fund sought to capitalize on the restructuring trend, and this has
had a positive impact on the Fund's performance.

What happened in the U.K.?

The stock market was up about 15% for 1996, which generally sounds good, but was
modest in light of markets like Spain, Finland, and Sweden that advanced more
than 40%. Since the Fund was underweighted in the U.K., its performance had a
generally positive, but not a major impact on the Fund.

How was currency risk managed throughout the year?

Generally speaking, selective hedging was used to manage currency risk.
Throughout the year, this had a positive impact on performance.

Looking forward what do you see?

We believe we will continue to see the dollar strengthening against other
currencies in the long term. However, the dollar's protracted upward move might
have temporary setbacks. The Fund's managers are carefully watching the
situation.

Which markets do you like for 1997?

We'll be moving more into core markets, such as Germany, France, and the
Netherlands, if we continue to believe restructuring in these markets is likely
to have the greatest impact in the shortest amount of time. We believe exporting
markets are likely to continue to do well, but we are likely to place more
emphasis in Europe than in Asia, at least for the foreseeable future. As far as
Japan is concerned, until we see signs of a turnaround, we may continue to
reduce the Fund's positions. Overall, we'll continue to focus on developed
markets and established companies, seeking long-term growth of capital with an
acceptable level of risk.

These may include securities markets that are less efficient, less liquid and
more volatile than those in the United States, as well as foreign currency
fluctuations and different governmental regulatory concerns.

1996 MARKET HIGHLIGHTS
- --------------------------------------------------------------------------------
 . The U.S. stock market, as measured by the S&P 500 Stock Index,+ rose 22.94%
  for the year ended 12/31/96

 . The bond market, as represented by the Salomon Brothers Broad Investment
  Grade Index(S), gained only 3.62% for the year ended 12/31/96

 . Several foreign markets provided strong returns during the year

1996 FUND HIGHLIGHTS
- --------------------------------------------------------------------------------
 . For the year ended 12/31/96, the MainStay Institutional Multi-Asset Fund
  returned 16.16% and 15.89% for Institutional Class shares and Service Class
  shares, respectively
  
 . Through most of 1996, with a brief exception in August and September, the
  Fund was primarily invested in stocks near its maximum allowable weighting
  and bond and money market allocations were near their minimum levels
  
 . The Fund used investments in Germany, the U.K., and Australia to enhance
  returns and diversify the portfolio

In the United States, strong earnings, low interest rates, and the absence of
significant inflation continued to drive stocks higher during the year, with the
S&P 500 Stock Index returning 22.94% for the 12 months ended 12/31/96. While the
bull market for stocks continued through most of the year, bonds generally
provided meager results. For the year ended 12/31/96, the Salomon Brothers Broad
Investment Grade (BIG) Index returned just 3.62%. Surprisingly, the average
Lipper* institutional money market fund outperformed bonds in general, returning
5.16% over the same period.

In July and in December, the U.S. stock market underwent market corrections that
somewhat tempered the annual return of the S&P 500 Stock Index. During these
periods, however, several international markets did well, providing
opportunities for investors seeking broad geographic diversification.

Given this context, how did the MainStay Institutional Multi-Asset Fund do?

Very well. For the year ended December 31, 1996, the Fund returned 16.16% and
15.89% for Institutional Class and Service Class shares, respectively. Both
share classes outperformed the 13.59% return of the average Lipper flexible
portfolio fund over the same period.

================================================================================

What accounted for the strong performance of the Fund?

Successful asset allocation was a key factor. Recognizing that stocks had the
greatest return potential, the Fund's average allocation to stocks throughout
the year was 72%. This allocation was close to the Fund's maximum allowable
equity exposure of 80%, and was a primary contributor to the Fund's positive
results. Unfortunately, following the market downturn in July, bonds appeared to
be more attractive on a risk-adjusted basis and the Fund's stock allocation was
reduced to its minimum level of 30%. When stocks rebounded strongly in August
and September, our lower weighting in stocks and higher weighting in bonds
detracted from overall performance.

How did the bond portion of the portfolio perform?

Except in August and September, we kept the bond portion of the portfolio at its
minimum level of 10%. The bond portion closely tracked the Salomon Brothers
Broad Investment Grade Index, which returned 3.62% for the year. The money
market portion of the portfolio never rose above a 10% allocation, since our
quantitative allocation models consistently identified greater opportunities
elsewhere.

Where else did the Fund invest?

With several foreign markets providing double-digit returns, the Fund benefited
from small allocations to international markets. In the first four months of the
year, 5% of net assets was invested in the German stock market. During that
period, the DAX** rose 11.15% in local terms. In April, 5% was invested in the
United Kingdom, whose FTSE++  index rose 3.6% in local terms for the month. In
December, small allocations to Australia, Germany, and the U.K. enhanced
returns. These markets rose 2.24%, 1.52% and 1.77%, respectively in local terms
for the month, while the U.S. market lost 1.98%.

Don't foreign investments involve additional risks?

Foreign investing may be subject to greater risks than domestic investing. These
may include securities markets that are less efficient, less liquid and more
volatile than those in the United States, as well as foreign currency
fluctuations and different governmental regulatory concerns. On the other hand,
broad geographic diversification has the potential to enhance returns, spread
risk, and reduce the expected volatility of the Fund as a whole. We feel that
our foreign investments contributed positively to the Fund in each of these
respects in 1996.

VALUE EQUITY FUND
================================================================================

- --------------------------------------------------------------------------------
1996 MARKET HIGHLIGHTS
- --------------------------------------------------------------------------------
 .  A variety of factors converged to make year-end 1996 an excellent year for
    value stocks

 .  Corporate acquisition activity reached record levels during the year

 .  A stock market downturn in July brought low-valuation stocks to record low
    levels, which marked a significant turning point for value equities

 .  Value stocks experienced exceptional returns in the fourth quarter and
    outpaced growth equities for the year

- --------------------------------------------------------------------------------
1996 FUND HIGHLIGHTS
- --------------------------------------------------------------------------------
 .  One-year total returns of 22.41% and 22.10% for Institutional Class and
    Service Class shares, respectively, as of 12/31/96

 .  Institutional Class shares received a five-star overall rating from
    Morningstar, Inc.++ as of 12/31/96

 .  Both share classes outperformed the average Lipper* growth and income fund

 .  The Fund identified value and free cash flow in a number of companies that
    also attracted acquirers

 .  Our focus on consumer cyclicals and basic materials benefited the portfolio

- --------------------------------------------------------------------------------
Consumer cyclicals Consumer products and services whose sales tend to rise and
fall with changes in the economic cycle.

Bottom-up investing Security selection based on the specific 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.

Correction A shift in security prices which brings them more in line with
historic averages.
- --------------------------------------------------------------------------------

For the first nine months of 1996, slow economic growth favored the growth
equity discipline. A severe market downturn in July, however, brought low-
valuation stocks to their lowest levels in recent history, marking a significant
turning point for the value market. When the economy picked up in the fourth
quarter, value stocks were poised for rapid advances and value stocks generally
outperformed growth equities through the end of the year.

Extremely low valuations among companies with strong fundamentals and free cash
flow also triggered a record level of merger and acquisition activity during
1996. This was very beneficial for value investors, who seek companies that are
generally undervalued by the marketplace and often make attractive acquisition
candidates.

While stock market returns for 1996 were more than twice the average annual
total return for the previous 70 years(S) the advances were primarily

++   Morningstar, Inc. is an independent fund performance monitor. Its ratings
     reflect risk-adjusted performance, which does not include sales charges,
     and may change monthly. Its ratings of 1 (low) and 5(high) stars are based
     on a fund's 3-, 5- & 10-year average annual returns with fee adjustments,
     and a risk factor that reflects fund performance relative to 3-month
     Treasury bill monthly returns. A one-year rating is calculated using the
     same methodology, but is not a component of the overall rating. As of
     12/31/96, the individual 1, 3 and 5 year ratings for the MainStay
     Institutional Value Equity Fund was 4, 4 and 5 stars, respectively. For the
     one-year period, the Fund was rated among 2,959 funds in the domestic
     equity category. Only 10% of the funds in an investment category may
     receive 5 stars and 22.5% may receive 4 stars. Ratings reflect
     Institutional Class performance only. Service Class shares, first
     introduced January 1, 1995, will not be rated by Morningstar until they
     have a three year operating history.

Recovery  A market recovery refers to a rise in security prices, which were
formerly depressed. An economic recovery refers to a general improvement in
formerly weak fundamentals underlying a country's gross domestic product, which
may include factory output, sales, productivity, employment, and relative
currency values.

concentrated in a small number of issues. With 25% of the stocks in the Dow
Jones Industrial Average accounting for 90% of its gains, individual security
selection was a key factor in determining performance. For the year, the average
Lipper growth & income fund provided a total return of 20.78%.

Given this context, how did the MainStay Institutional Value Equity Fund do in
1996?

The Fund had a strong year. For the 12 months ended December 31, 1996, the
MainStay Institutional Value Equity Fund returned 22.41% and 22.10% for
Institutional Class and Service Class shares, respectively. Both share classes
outperformed the average Lipper growth and income fund, which returned 20.78%
for the same period.

The Fund earned Morningstar's highest overall ranking of five stars, placing it
among the top 10% of funds in its Morningstar universe.  The Value Equity Fund's
individual Morningstar ratings for the three- and five-year periods ending
12/31/96 were 4 stars and 5 stars, respectively, out of a universe of 1,826 and
1,058 funds in the domestic equity category for their respective periods.

What were the primary reasons for the Fund's outperformance?

The Fund's bottom-up approach to value investing is based on individual security
selection and emphasizes companies with low price to earnings ratios and
substantial free cash flow. Using this approach, the Fund was able to ride out
the ups and downs of the market and achieve superior returns. In addition, this
year a number of companies selected for their fundamental value also attracted
the attention of acquirers, which helped the Fund's holdings in these stocks
appreciate significantly--and in many cases, the acquirer's securities were kept
in the Fund's portfolio after the transaction was completed.

What are some examples of these acquisitions?

In the first quarter, U.S. Healthcare was taken over by Aetna, which was highly
positive for the portfolio, and we took Aetna's securities into the portfolio.
First Interstate Bank was acquired by Wells Fargo, and the Fund also took Wells
Fargo stock into the portfolio. Also in 1996, we saw strong fundamentals and
free cash flow in Vigoro, a fertilizer company, and Varity, an auto-related
company. Consolidation efforts within these industries brought high premiums for
these stocks. In the third quarter, Boatmen's Bancshares was purchased by
NationsBank, and later in the quarter, Conrail received a bid from CSX, which
escalated into a bidding war with Norfolk Southern. In the fourth quarter, Long
Island Lighting Co. received a bid from Brooklyn Union Gas. All of these
transactions were highly positive for the Fund's shareholders.

Did everything in the portfolio do that well?

No. In the second quarter, the Fund bought AT&T, and shortly afterward, AT&T's
president left, the chairman's outlook became less robust, deregulation set in,
all resulting in a decline in stock price. The Fund sold the stock in the fourth
quarter at a 10% loss. In financial services, the Fund bought Torchmark and
Providian after the market correction in July. When these stocks didn't
participate in the uptrend that followed, we revisited our decision and decided
to sell. Although the transactions were relatively neutral, this caused the Fund
to miss some opportunities since the financial services sector advanced 20% by
year end. Another disappointment was Hanson PLC, an international conglomerate,
which was a breakup candidate. Often, companies realize value by dividing into
separate units. But in this case, the European economy went down and each
component lost earning power. The Fund ended up selling all four pieces of the
company at a loss, which took a toll on performance.

Were there other stocks sold?

Yes, the Fund had some positive sales. For example, IBM went up 50%** in six
months, which was the Fund's signal to sell--in this case at a substantial gain.
Gateway 2000 went up 100% in 6 months, so the Fund

================================================================================

doubled its money when sold. Intel, which was purchased late in the first
quarter rose substantially within weeks. It was sold in the second quarter at a
substantial gain.

If the stocks were rising so fast, why were they sold?

Part of the Fund's value discipline is to sell stocks when their value has been
realized. The Fund's strategy is to try to buy low and sell high. Even if a
stock is shooting for the moon, it will not be held if we feel it is approaching
or has reached its fair market value.

How did the Fund perform during the market downturn in July?

Generally, the Fund seeks to perform with or ahead of the market as it rises and
significantly better than the market when it declines. During the correction in
July, value stocks were definitely hurt, but the Fund's portfolio performed
according to its disciplines and outperformed the market by year end. Since the
Fund's objective is to own undervalued issues, the decline in values actually
presented new opportunities. In fact, it made the Fund's positions even more
attractive. As we had hoped, many of the Fund's stocks showed considerable
advances during the recovery later in the year. So our decision to hold on to
these declining issues was very positive for investors by year end.

Why was there a concentration on consumer cyclicals throughout the year?

We were anticipating an upturn in the economy. While the Fund had to weather a
downturn to get there, endurance paid off by year end. When the economy picks
up, consumers go out and buy things. That's good for retailers like Sears,
Federated Department Stores, and J.C. Penney. It's also good for companies that
make the products consumers buy, like Fruit of the Loom, Reebok International,
and General Motors. The Fund held stock in all of these companies during the
year.

Were there other areas that did well?

Yes, it was a good year for energy, and Parker & Parsley, a stock in this sector
the Fund owned, was up 63% for the year. One of the Fund's railroad holdings,
Conrail, which is in the takeover process, also performed well. Financial stocks
also did well. We found value in Traveler's (+47%), Allstate (+46%), Bankers
Trust (+35%), and with the takeovers at Boatmen's Bancshare and First
Interstate. Unfortunately, the Fund reduced its exposure to financials during
the year, which negatively impacted performance. If rates rise and financials
return to lower levels, we may look for buying opportunities in 1997 in the
financial services sector.

What else do you see ahead for 1997?

Right now, our proprietary research is pointing in more conservative directions,
with utilities showing unusual strength. This may signal a return to more
typical stock performance, or simply the possibility of higher volatility. We'll
continue to seek to identify attractive value candidates, and we're hoping that
1996 has signaled that value investing will be in favor for an extended period.
Whatever the markets bring, we'll seek to realize maximum long-term total return
from a combination of capital growth and income.

**  Performance figures for the Service Class, first offered to the public on
    1/1/95, include the historical performance of the Institutional Class from
    the Fund's inception (1/2/91) up to December 31, 1994. Performance figures
    for these two Classes after this date will vary based on differences in
    their expense structures.

*   The total return reflects the annual return on an investment including
    appreciation and dividends or interest. Total returns shown herein include
    the change in share price and reinvestment of capital gains distributions
    and dividends, and, for the Service Class shares, include the service fee of
    .25%.

    Past performance is no guarantee of future results.  Investment return and
    principal value will fluctuate so that upon redemption, shares may be worth
    more or less than their original cost.

    The Institutional Class shares are sold with no sales charge. The Service
    Class shares, first offered 1/1/95, are sold with no initial or contingent
    deferred sales charge, but are subject to an annual shareholder service fee
    of .25%.

BOND FUND
================================================================================

- --------------------------------------------------------------------------------
1996 MARKET HIGHLIGHTS
- --------------------------------------------------------------------------------
 .  Total returns of government securities were up slightly in 1996, with
   performance determined primarily by rising interest rates

 .  Mortgage-backed securities were a strong relative performer in 1996,
   outperforming the Treasury market each month

 .  Corporate and asset-backed securities also generally outperformed Treasury
   securities during the year

 .  The addition of two 10-year Treasury auctions and one 30-year auction
   affected supply, pricing, and demand within the government securities market

- --------------------------------------------------------------------------------
1996 FUND HIGHLIGHTS
- --------------------------------------------------------------------------------
 .  The MainStay Institutional Bond Fund returned 2.80% and 2.62% for
   Institutional Class shares and Service Class shares, respectively, for the 12
   months ended 12/31/96

 .  Duration, a major determinant of fixed-income performance helped the Fund in
   the second and fourth quarters, but was offset in the first and third
   quarters.

 .  The Fund took advantage of the strong performance of Yankee bonds and
   seasoned mortgage-backed securities with specific origination years, to boost
   performance throughout the year

 .  A variety of other mortgage-backed securities also performed well for the
   Fund

- --------------------------------------------------------------------------------
Auction  The competitive bidding process through which Treasury securities are
sold.

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).

Yield spread  The difference in yield between securities in different market
sectors, such as mortgage-backed securities and Treasury issues -- or between
different securities in a single sector, such as short-term and intermediate-
term Treasury issues.
- --------------------------------------------------------------------------------

While 1996 was a weak year for bonds overall, there were significant
opportunities for investors. Even with a slight reduction in rates by the
Federal Reserve Board on January 31, stalled budget talks and signs of a
strengthening economy caused rates to rise through the first half of the year.
In the second half, rates declined but began to rise again in December. The
result was considerable volatility in bond prices throughout the year.

The introduction of additional auctions for 10- and 30-year Treasuries redefined
supply dynamics within the U.S. government bond market and created additional
opportunities for selective movements among newer and older issues. Mortgage-
backed securities outperformed Treasuries most months in 1996, and Yankee bonds
did well throughout the year. Corporate and asset-backed securities also offered
attractive yield spreads to Treasuries early in the year. At year-end, the
Treasury Department announced the first issuance of inflation-indexed bonds
scheduled for a January auction. This new asset class will focus on real rates
of return and may present attractive opportunities going forward.

Given this context, how did the MainStay Institutional Bond Fund do in 1996?

For the 12 months ended 12/31/96, the MainStay Institutional Bond Fund provided
returns of 2.80% and 2.62% for Institutional Class shares and

                                       79

================================================================================

- --------------------------------------------------------------------------------
Duration  A measure of average maturity, 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.

Exposure  The amount invested in a specific security, market, country, or
currency. Participation in positive as well as negative events affecting a
security or sector generally increases with the level of exposure.
- --------------------------------------------------------------------------------

Service Class shares, respectively. Both share classes ranked within the top 50%
of funds in the Lipper* intermediate U.S. government fund category for the year.

What were the primary factors that influenced the Fund's performance?

Interest rates, which generally rose in the first half of the year and declined
in the second, had a major impact on the Fund. We believe that duration is the
primary determinant of performance in fixed-income portfolios and our strategy
throughout the year was relatively conservative i.e., the duration of the Fund
closely tracked the duration of the Fund's benchmark, the Lehman Brothers
Government/Corporate Bond Index.+ This helped the Fund's performance in the
second and fourth quarters, with offsetting results in the first and third
quarters. We substantially increased our exposure to mortgage-backed securities
during the year, which had a positive effect on the portfolio as they increased
in value.

What types of mortgage-backed securities did the Fund buy?

There were several. In the seasoned mortgage market, we purchased securities
based on specific origination years, which was profitable as spreads narrowed
and the strategy gained broader market acceptance. The Fund also bought
securities backed by commercial mortgages, manufactured housing mortgages, and
low-loan balance mortgages. Each of these securities has features that may help
protect against prepayment risk. Late in the year, the Fund also purchased
adjustable rate mortgage securities issued by GNMA and FNMA, which we believe
will continue to benefit from low and stable prepayments. Finally, FNMA Multi-
Family Delegated Underwriting Servicers issues offered attractive yields,
prepayment protection, and call protection until six months prior to maturity.
With the exception of the most recent purchases, all of these securities have
contributed positively to performance throughout the year.

Where else did you seek to enhance yields?

The Fund owned high-quality corporate bonds that offered attractive yield
spreads to Treasuries and sold them as spreads narrowed and the bonds became
overvalued. Yankee bonds also performed well.

What exactly are Yankee bonds?

They're dollar-denominated securities issued in the United States by foreign
issuers, including banks and corporations, usually when conditions in the U.S.
market are more favorable than in those foreign markets.

Why were they a good selection?

Careful research, the Fund's security selection process and time devoted to get
to know this market, which many other bond investors are just starting to
consider, has been important. By overweighting the Fund's portfolio in carefully
selected Yankee bonds, purchases were made at attractive valuation levels, which
benefited our shareholders throughout the year.

================================================================================

What mistakes affected the Fund's performance during the year?

Although there was no individual portfolio holding that influenced the overall
performance of the Fund, our modest duration adjustments, which added value in
the second and fourth quarters, were offset in the first and third quarters. The
fund could also have benefited from more exposure to innovative mortgage-backed
securities throughout the year.

What's your outlook for 1997?

We don't anticipate any major moves by the Federal Reserve in the early part of
the year. We think the 30-year Treasury bond is likely to trade in a range from
6.5% to 7.5% for a while, and we will continue to monitor the economy and
inflation expectations to determine when and how rates are likely to break out
of this range. Whatever develops, we'll continue to seek debt securities that
offer a combination of quality, current income, total return potential, and low
principal risk.

INDEXED BOND FUND
================================================================================

- --------------------------------------------------------------------------------
1996 MARKET HIGHLIGHTS
- --------------------------------------------------------------------------------
 .  Overall, the U.S. investment-grade bond market was relatively weak in 1996,
   providing meager returns for investors

 .  Yields on 30-year Treasuries rose from 5.95% at the beginning of the year to
   over 7% during the summer and closed the year at 6.64%

 .  Price volatility made the year a difficult one for bond investing

 .  Mortgage-backed securities were the strongest performing sector of the
   Salomon Brothers Broad Investment Grade (BIG) Index,+ returning 5.37% for the
   year ended 12/31/96

- --------------------------------------------------------------------------------
1996 FUND HIGHLIGHTS
- --------------------------------------------------------------------------------
 .  MainStay Institutional Indexed Bond Fund provided total returns of 2.55% and
   2.34% for Institutional Class shares and Service Class shares, respectively,
   for the year ended 12/31/96

 .  The Fund negatively tracked the performance of the Salomon Brothers Broad
   Investment Grade Bond Index, which returned 3.62% for the year ended 12/31/96
  
- --------------------------------------------------------------------------------
Price volatility  Fluctuations in the price of securities, which in the fixed-
income markets is often related to changes in interest rates. Typically as
interest rates rise, bond prices decline, and as interest rates lower, bond
prices rise.

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.

Basis  point One hundredth of one percent in the yield of an investment, e.g.,
100 basis points equals 1%.
- --------------------------------------------------------------------------------

While stocks advanced strongly in 1996, the U.S. investment-grade bond market
suffered from high price volatility and provided only meager returns. The 30-
year Treasury bond yielded 5.95% at the beginning of the year, which is
extremely low by historical standards. Bond investors had reason to worry when
the economy showed signs of heating up and the Federal Reserve made its first
and only move of the year at the end of January, cutting rates by 25 basis
points. Throughout the rest of the year, bond yields took a somewhat wild and
meandering ride, rising to over 7% in the summer and declining to 6.64% by the
end of the year. Although yields were volatile over the course of the year, the
absolute change for the long bond was only a 0.69% rise.

Since bond prices generally move in the opposite direction of interest rates,
price volatility was also a concern for investors during the year. The best
performing sector of the Salomon Brothers Broad Investment Grade Index was
mortgage-backed securities. The mortgage-backed securities within the Index
returned 5.37% in 1996.

Other bond sectors provided superior returns, largely because they carry higher
risk than the investment-grade securities that make up the Salomon Brothers BIG
Index. For example, the average Lipper* high current yield fund returned an
impressive 13.27%, and the average Lipper emerging market debt fund returned an
incredible 41.88%. During 1996, the Salomon Brothers Broad Investment Grade
Index returned a modest 3.62%.
- --------------------------------------------------------------------------------
+   The Salomon Brothers Broad Investment Grade Bond Index is an unmanaged index
    that is considered representative of the U.S. bond market.

================================================================================

- --------------------------------------------------------------------------------
Mortgage-backed securities  Securities representing interest 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).

Investment-grade securities  Bonds rated BBB or better by Standard & Poor's, or
Baa or better by Moody's rating services.
- --------------------------------------------------------------------------------

Given this context, how did the MainStay Institutional Indexed Bond Fund do?

For the year ended 12/31/96, the MainStay Institutional Indexed Bond Fund
returned 2.55% and 2.34% for Institutional Class shares and Service Class
shares, respectively. The Fund seeks to track the performance of the Salomon
Brothers BIG Index, which provided a higher return in 1996.  The difference in
returns between the Fund and the Index may be attributed to the Fund's fees and
expenses and to tracking error.  Tracking error, or the Fund's ability to track
the Index, may be affected by, among other things, transaction costs, changes in
either the composition of the Index or number of bonds outstanding for the
components of the Index, and the timing and amount of contributions to and
redemptions from the Fund by shareholders.  The size and timing of isolated
withdrawals contributed significantly to the Fund's tracking error in 1996.

How did the Fund compare with other broad market measures?

The average Lipper fixed income fund returned 4.69% for the year ended 12/31/96.
It's important to note, however, that this includes the performance of funds
with higher-risk investments than the Salomon Brothers Broad Investment Grade
Index, such as junk bonds, non investment-grade high yield bonds and emerging
market debt.

If other sectors are doing better, what are the potential advantages of this
Fund?

Total return is just one aspect of a portfolio. Investors must also evaluate an
investment in terms of its quality. The Salomon Brothers BIG Index invests
primarily in U.S. Treasury and agency securities, high-grade corporate debt
securities, and mortgage-backed bonds. These are among the highest quality
securities in the bond markets and may be appropriate for risk-averse investors
seeking a combination of quality and diversity across several types of
investment-grade income investments. The Fund may be an appropriate addition to
growth portfolios seeking an income component. It may also provide a sensible
way to manage the overall risk of higher-yielding income portfolios.

Why did mortgage-backed securities do so well in 1996?

Mortgage-backed securities generally have higher yields than the yields, and
ultimate safety, offered by Treasury securities. They are also less sensitive to
interest rate increases than the longer-duration corporate sector. When interest
rates rise, there's less likelihood of people prepaying their mortgages, which
tends to make the performance of mortgage-backed securities more predictable,
helping to manage investment risk. This factor may have contributed to the
higher relative performance of mortgage-backed bonds.

What factors are likely to influence the bond markets going forward?

There can be little doubt that interest rates, the rate of economic growth, and
the possibility of inflation will continue to influence bond prices and yields.
The Federal Reserve has not taken any action to directly influence interest
rates since January 31, 1996, but may step in if inflationary pressures, an
economic upsurge, or a sudden weakening in economic fundamentals should occur.

**  Performance figures for the Service Class, first offered to the public on
    1/1/95, include the historical performance of the Institutional Class from
    the Fund's inception (1/2/91) up to December 31, 1994. Performance figures
    for these two Classes after this date will vary based on differences in
    their expense structures.

*   The total return reflects the annual return on an investment including
    appreciation and dividends or interest. Total returns shown herein include
    the change in share price and reinvestment of capital gains distributions
    and dividends, and, for the Service Class shares, include the service fee of
    .25%.

    Past performance is no guarantee of future results. Investment return and
    principal value will fluctuate so that upon redemption, shares may be worth
    more or less than their original cost.

    The Institutional Class shares are sold with no sales charge. The Service
    Class shares, first offered 1/1/95, are sold with no initial or contingent
    deferred sales charge, but are subject to an annual shareholder service fee
    of .25%.

    Unlike other funds which generally seek to "beat" the market, index funds
    seek to "match" their respective indices.

+   Actual percentages will vary over time. Bond quality ratings provided by
    Standard & Poor's. See the prospectus for details.

================================================================================

- --------------------------------------------------------------------------------
1996 MARKET HIGHLIGHTS
- --------------------------------------------------------------------------------
 .  The strength of the U.S. dollar relative to other currencies increased the
    risk of unhedged international bond investments

 .  European monetary union requirements forced governments to reduce their
    deficits, which led to lower European interest rates and a European bond
    market rally

 .  Many emerging markets offered outstanding performance throughout the year

 .  Overall, international bonds outperformed U.S. debt securities, and on a
    hedged basis, the results were even more dramatic

- --------------------------------------------------------------------------------
1996 FUND HIGHLIGHTS
- --------------------------------------------------------------------------------
 .  One-year total returns of 14.32% and 14.08% for Institutional Class and
    Service Class shares, respectively, as of 12/31/96

 .  Both share classes outperformed the average Lipper* international income
    fund and the Salomon Brothers Non-U.S. Dollar World Government Bond Index/+/
    for the 12 months ended 12/31/96

 .  Risk management strategies included hedging against the U.S. dollar and the
    Deutsche mark seeking to minimize unfavorable currency exposure

 .  The Fund had favorable results from country allocation, especially in Spain,
    Italy, Sweden, and Canada

- --------------------------------------------------------------------------------
Hedging   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 be
beneficial to investors.

Weighting   The proportion of a portfolio allocated to a specific market sector 
or country, i.e., a fund is said to be overweighted in a country when that
portion of the portfolio is larger than the country's total bonds relative to
international bond markets as a whole.
- --------------------------------------------------------------------------------

1996 was a strong year for international bonds. While some markets, such as
Japan, provided minimal returns, emerging markets provided spectacular results
of 34.6%.** Other major developed markets also turned in excellent results, with
Italy and Spain up 22% in local terms, Sweden up 18%, and Canada up 11.8%.
Although the Canadian market wasn't the top performer, it picked up
substantially at the end of the year, providing a 5% return in the fourth
quarter alone.

Signs of economic recovery in Japan gave the bond markets a scare in the first
quarter. With the suggestion that short-term rates had bottomed out in Japan,
investors started selling bonds on fears that rates would rise. While the
phenomenon was short-lived, it had an impact around the world.

In Europe, economic reform and fiscal consolidation led to dramatically lower
interest rates, which fueled a European bond market rally. The strengthening
U.S. dollar relative to most major currencies posed a risk for international
bond investors. While international bond returns were attractive on a local
basis, they were particularly strong when effectively hedged.

International diversification  Purchasing securities in several international
markets, which may react differently to economic, monetary, and market trends.
Diversification may provide opportunities for investors to pursue higher returns
while managing the risks of investing only domestically.

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." The "front end" of the yield curve, then, would consist of
short- to intermediate-term bonds which generally offer lower interest rates
than longer term investments.
- --------------------------------------------------------------------------------

Given this background, how did the MainStay Institutional International Bond
Fund do in 1996?

For the 12 months ended December 31, 1996, the MainStay International Bond Fund
provided total returns of 14.32% and 14.08% for Institutional Class shares and
Service Class shares, respectively. These results placed the Fund well ahead of
the average Lipper international income fund, which returned 8.75%, and the
Salomon Brothers Non-U.S. Dollar World Government Bond Index, which returned
4.08%, over the same period.

What were the major contributors to this positive performance?

There were several themes that helped the portfolio. First, the Japanese market,
where returns were much too low to compensate for the risk, was avoided
completely. Second, selective use of currency hedging against both the U.S.
dollar and the Deutsche mark, gave the Fund's performance a considerable boost.
Third, we selected strong markets and overweighted the portfolio where we felt
returns would be highest. And fourth, we adjusted duration throughout the year
in ways that benefited the portfolio.

Why was hedging so important this year?

The U.S. dollar was strengthening most of the year against many major
currencies. Hedging is a risk management strategy that helped avoid giving back
the gains made in the local markets when the returns were translated into
dollars. In some cases, the Fund benefited from remaining unhedged, as with
Australian bonds during the first half of the year when the Australian dollar
increased in value. But most of the Fund's investments were hedged for most of
the year, which enhanced the performance of the portfolio.

Can you give an example of a currency used to hedge the Fund?

We used the Deutsche mark as a hedging vehicle for the Fund's Italian, Spanish,
and Swedish government bond positions. That allowed the Fund to help protect its
foreign bond returns from dollar strength and to recoup most or all the capital
gains and interest income from them without having to take currency losses when
returns were translated back into dollars.

Which countries did you concentrate in during 1996?

While the Fund invests in a diversified array of markets, we concentrated in a
few we thought would be stellar performers. We like Canada because it's already
been through the pain of fiscal consolidation and currency weakness that Europe
is just now going through. It's an export giant, has huge surpluses with the
United States, and is the United State's largest trading partner. We felt
Canadian bonds represented excellent value and would provide attractive yields.
So there's a lot to like there.

Where else were the Fund's investments focused?

In Europe, we focused on Italy, Sweden, and Spain. Several European currencies
have rallied in 1996, including the Italian lira which increased 12% versus the
Deutsche mark and Swedish currency which rose 5%. But each of these countries
provided much higher yields than German bonds, so the Fund benefited from
returns of 22% in Italy and Spain and 18% in Sweden, as well as making money on
the currency. We believe that the vast majority of an international bond
portfolio's return will come from its country and currency selections. And they
both paid off for the Fund during the year.

================================================================================

How and why did you adjust the duration of the portfolio in 1996?

With the Japanese bond scare, fears of U.S. rate hikes, and the threat of a bond
sell-off, we shortened our duration in Belgium, Germany, Denmark, and the dollar
block countries (Canada and Australia) in the first quarter, which was good for
the Fund by helping avoid losses when interest rates in these countries
increased. In the middle of the second quarter and throughout the rest of the
year, we increased our duration in Spain, Italy, and Sweden, which also had a
positive effect as those bond markets rallied. Duration stance, coupled with
country and currency weightings placed the Fund's investments in the right place
at the right time and helped the Fund outperform its peers.

What was the Fund's position in other European countries?

The Fund wasn't heavily invested in the U.K., which was a laggard in 1996. The
U.K. market suffered political and economic risks, which may get worse if the
U.K. doesn't converge with other European nations in its monetary policies.
Generally, France traded very much like Germany, and the Fund's underweighted
position was a positive for the Fund as other country holdings recorded higher
returns for the Fund.

Where was the Fund positioned on the yield curve throughout the year?

The Fund stayed largely at the front end of the yield curve, or in shorter-term
paper with maturities from two to ten years. We didn't find the added yield that
we may have obtained by buying longer-term bonds was worth the risks the Fund
would have to take. Yield curve decisions also contributed to the Fund's
positive performance in 1996.

Did you make any major mistakes during the year?

Looking back, I think our biggest mistake was avoiding emerging markets
entirely. The rise in oil prices helped a lot of emerging market economies, most
notably Venezuela and Mexico. We may have missed some important opportunities by
not taking advantage of these markets at least to some degree.

What do you see ahead for 1997?

We will probably continue to be overweighted in shorter-term bonds, unless the
direction of the market changes. We're continuing to look at Italy, which tends
to be very volatile from a political standpoint. We're maintaining an open mind
about small exposure in emerging markets. And naturally, we'll continue to seek
out promising countries, currencies, and securities that have the potential to
maximize current income for our shareholders, with a reasonable level of risk.

Note: Foreign investing may be subject to greater risks than domestic investing.
These may include securities markets that are less efficient, less liquid and
more volatile than those in the United States, as well as foreign currency
fluctuations and different governmental regulatory concerns.

MONEY MARKET FUND
================================================================================

- --------------------------------------------------------------------------------
1996 MARKET HIGHLIGHTS
- --------------------------------------------------------------------------------
 .  Primary influences on the money markets included Federal Reserve action and
    perceptions of whether and when the Fed would make additional moves

 .  Market participants closely watched key barometers of economic and
    inflationary activity, seeking to anticipate where rates would move

 .  The money market experienced a fair amount of volatility during the year,
    with alternating weak and strong quarters.

- --------------------------------------------------------------------------------
1996 FUND HIGHLIGHTS
- --------------------------------------------------------------------------------
 .  The MainStay Institutional Money Market Fund returned 5.11% and 4.85% for
    Institutional Class shares and Service Class shares, respectively, for the
    12 months ended 12/31/96

 .  Duration management was a major determinant of the Fund's performance

 .  Duration decisions had positive effects in the first and fourth quarters,
    but weakened results in the second and third quarters

- --------------------------------------------------------------------------------
Producer Price Index (PPI)   A measure of the change in wholesale prices, broken
out by commodity, industry sector, and stage of processing. The Index looks at
prices of food, metals, lumber, oil and gas, and other commodities, but does not
consider the price of services.

Consumer Price Index (CPI)   A standard measure of inflation, based on the 
changes in price of selected consumer goods and services.

Basis point   One hundredth of one percent in the yield of an investment, e.g.,
100 basis points equals 1%.
- --------------------------------------------------------------------------------
The money markets faced a see-saw year in 1996, as fixed-income securities in
general felt the ebb and flow of market anticipation of interest rate trends.
Investors paid close attention to key economic and inflationary forces they felt
might influence Federal Reserve decisions, including economic growth, the
Producer Price Index (PPI), the Consumer Price Index (CPI), and demand for
labor.

The Federal Reserve only made one move during the year, reducing the federal
funds rate by 25 basis points on January 31. Without further action, interest
rate movements continued to swing high, low, and in between, based on
anticipation of economic trends. The volatility of the markets provided a
challenge to investors who saw fewer clear signals of where the market was
headed than in previous years.

Given this context, how did the MainStay Institutional Money Market Fund do?

For the 12 months ended December 31, 1996, the MainStay Institutional Money
Market Fund returned 5.11% and 4.85% for Institutional Class shares and Service
Class shares, respectively. This compared to a 5.16% return for the average
Lipper* institutional money market fund.

Our biggest challenge was anticipating the direction of interest rates during
the year and modifying the portfolio's duration to take advantage of changes as
they occurred. In January, we expected to see easing short-term rates and
lengthened our duration accordingly. That had a positive effect when the Federal
Reserve reduced rates at the end of January. Unfortunately, as signals of a
strengthening economy began to emerge, we shortened our duration, anticipating a
tightening move which never occurred.

================================================================================

- --------------------------------------------------------------------------------
Duration   A measure of average maturity, 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.

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 percent of the fund's current price per
share.
- --------------------------------------------------------------------------------

Why didn't the Federal Reserve take any action?

We believe that a stock market downturn, positive corporate earnings, and
investor anticipation of Fed action provided sufficient constraints to keep
inflation in line and the economy on a steady course.

How did your decision to shorten duration affect the Fund?

Basically, it hurt the Fund in the second and third quarters, as the shorter-
maturity instruments the Fund owned provided lower returns than the longer-
maturity issues the Fund could have purchased. By the beginning of the fourth
quarter, we were convinced that the Fed would not take any action and lengthened
duration, which increased the Fund's yield. While this was perhaps our best
decision during the year, it was not enough to bring the Fund in line with the
average peer fund for the year.

Did you take other steps to enhance the Fund's yield?

Yes. Throughout the year, the Fund purchased short-term corporate securities
when we felt they were cheap. Among the Fund's most significant purchases were
Citicorp, Wells Fargo, and Heller Financial Inc., all of which contributed
positively to the Fund's performance.

How would you rate the Fund's overall performance?

While falling short of the average Lipper fund can be mostly attributed to fees
and expenses, the Fund still had an excellent year in relative terms. The Fund,
as did money market funds in general, outperformed key fixed-income markets,
including long-term U.S. government securities, mortgage-backed securities and
high-grade corporate bonds in general. As a result, the MainStay Institutional
Money Market Fund was a relatively positive impact on diversified portfolios,
particularly ones invested in other domestic high-grade debt securities.

Do you think the Federal Reserve will take action again soon?

No. We believe that the economy will continue to grow within the range that is
considered to be sustainable over the long term, which is currently 2.0% to
2.5%. We don't anticipate any Federal Reserve action in the first quarter, and
possibly not in the first half of 1997. In any case, we'll continue to seek a
high level of current income, while preserving capital and maintaining liquidity
for our shareholders.

(as of 12/31/96)

- --------------------------------------------------------------------------------
**  Performance figures for the Service Class, first offered to the public on
    1/1/95, include the historical performance of the Institutional Class from
    the Fund's inception (1/2/91) up to December 31, 1994. Performance figures
    for these two Classes after this date will vary based on differences in
    their expense structures.

*   The total return reflects the annual return on an investment including
    appreciation and dividends or interest. Total returns shown herein include
    the change in share price and reinvestment of capital gains distributions
    and dividends, and, for the Service Class shares, include the service fee 
    of .25%.

    The Money Market Fund-Institutional Class had a 7- day effective yield of
    5.16% and a 7-day average yield of 5.04%, both as of 12/31/96. The Money
    Market Fund-Service Class had a 7-day effective yield of 4.91% with a 7-day
    average yield of 4.79%, both as of 12/31/96. The Administrator has agreed to
    assume a portion of the expenses for these Funds. Had certain expenses not
    been assumed by the Administrator, the 7-day effective yield and the 7-day
    average yield would have been 5.02% and 4.90%, respectively, for the
    Institutional Class and 4.76% and 4.65%, respectively, for the Service
    Class.

    Investments in the Money Market Fund are neither insured nor guaranteed by
    the U.S. Government, and there is no assurance that the Fund will be able to
    maintain a stable net asset value of $1.00 per share.

    Past performance is no guarantee of future results. Investment return and
    principal value will fluctuate so that upon redemption, shares may be worth
    more or less than their original cost.

    The Institutional Class shares are sold with no sales charge. The Service
    Class shares, first offered 1/1/95, are sold with no initial or contingent
    deferred sales charge, but are subject to an annual shareholder service fee
    of .25%.

SHORT-TERM BOND FUND
================================================================================

- --------------------------------------------------------------------------------
1996 MARKET HIGHLIGHTS
- --------------------------------------------------------------------------------
 .  Short-term U.S. government securities provided relatively modest returns in
    an environment driven primarily by interest rates

 .  Mortgage-backed securities provided strong relative performance,
    outperforming Treasury securities each month in 1996

 .  Corporate bonds also outperformed Treasury securities, providing
    opportunities for investors to increase yields and total returns

 .  Additional auctions for 10- and 30-year Treasury securities affected supply,
    pricing, and demand for government securities

- --------------------------------------------------------------------------------
1996 FUND HIGHLIGHTS
- --------------------------------------------------------------------------------

 .  The MainStay Institutional Short-Term Bond Fund returned 4.81% and 4.46% for
    Institutional Class shares and Service Class shares, respectively, for the
    12 months ended 12/31/96

 .  These results placed our Institutional Class shares and Service Class shares
    in the second and third quartiles, respectively, of all funds in the Lipper*
    short investment grade debt fund category

 .  The Fund's Institutional Class shares received a four-star overall rating
    from Morningstar Inc., ++ as of 12/31/96.
                           --

 .  The Fund pursued a yield-enhancement strategy based on innovative mortgage
    products, including manufactured housing mortgages and securities backed by
    low-loan balance mortgages

- --------------------------------------------------------------------------------
Basis point  One hundredth of one percent in the yield of an investment, e.g.,
100 basis points equals 1%.

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 percent of the fund's current price per
share.
- --------------------------------------------------------------------------------

After a strong year in 1995, government securities provided weak performance in
1996. Even with a 25 basis point rate reduction by the Federal Reserve at the
end of January, interest rates began to rise when budget talks stalled early in
the year and the economy showed signs of gaining strength. In the first quarter,
rising yields on long-term securities caused the yield curve to steepen. For the
rest of the year, however, the yield curve remained stable, within a narrow
range.

Throughout 1996, mortgage-backed securities outperformed Treasuries, and
corporate bonds also provided strong relative performance. The introduction of
- --------------------------------------------------------------------------------
*  Lipper Analytical Services Inc. is an independent monitor of mutual fund
   performance.  Results do not reflect any deduction of sales charges and are
   based on total returns with capital gains and dividends reinvested.

++ Morningstar, Inc. is an independent fund performance monitor. Its ratings
   reflect risk-adjusted performance, which does not include sales charges, and
   may change monthly. Its ratings of 1 (low) and 5 (high) stars are based on a
   fund's 3-, 5- & 10-year average annual returns with fee adjustments, and a
   risk factor that reflects fund performance relative to 3-month Treasury bill
   monthly returns. A one-year rating is calculated using the same methodology,
   but is not a component of the overall rating. As of 12/31/96, the individual
   1, 3 and 5 year ratings for the MainStay Institutional Short-Term Bond Fund
   was 4, 4 and 4 stars, respectively. For the one-year period, the Fund was
   rated among 1,670 funds in the taxable bond category. Only 10% of the funds
   in an investment category may receive 5 stars and 22.5% may receive 4 stars.
   Ratings reflect Institutional Class performance only. Service Class shares,

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.

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).

Auction  The competitive bidding process through which Treasury securities are
sold.

Yield spread  The difference in yield between securities in different market
sectors, such as mortgage-backed securities and Treasury issues -- or between
different securities in a single sector, such as short-term and intermediate-
term Treasury issues.
- --------------------------------------------------------------------------------

two new Treasury auctions for 10-year bonds and one new auction for 30-year
bonds shifted supply and demand dynamics and upset pricing in the government
securities market, which contributed to the lower returns in this sector.

Given this context, how did the MainStay Institutional Short-Term Bond Fund do?

The MainStay Institutional Short-Term Bond Fund returned 4.81% and 4.46% for
Institutional Class shares and Service Class shares, respectively, for the 12
months ended 12/31/96. This placed the two classes of shares in the second and
third quartiles, respectively, of all funds in their Lipper peer group for the
year. Both the Fund and its Lipper category peers lagged the Salomon 1-3 Year
Treasury Index,/+/  which returned 5.09% for the year.

The Fund's Institutional Class shares also received an overall four-star rating
from Morningstar Inc., placing them among the top 33% of the Morningstar
universe, which consisted of 1,140 taxable bond funds for the 3-year period and
597 taxable bond funds for the 5-year period ended 12/31/96.

How did you seek to enhance yields throughout the year?

Recognizing that Treasuries were unlikely to provide sufficient yield, the Fund
also invested in innovative mortgage products, including manufactured housing
mortgage and securities backed by low-loan balance mortgages. These securities
contributed positively to the Fund's performance throughout 1996. Later in the
year, the Fund also bought adjustable-rate mortgages, which we believe will have
a positive impact in 1997.

How did the Fund's corporate securities do during the year?

The Fund held a number of high-quality corporate bonds at the beginning of the
year, which outperformed Treasuries as yield spreads tightened. As the year
progressed, we reduced the Fund's position, feeling that the securities were
becoming overvalued and may begin to underperform other securities available to
the Fund. We also reduced the Fund's holdings in asset-backed securities, mostly
in automobile loans and credit-card debt, which outperformed during the year,
and moved the proceeds into mortgage-backed securities, so both the sales and
subsequent purchases helped the portfolio.

Did you make any mistakes during the year?

In hindsight, we can say that the Fund would have benefited from even greater
exposure to innovative mortgage-backed securities, which boosted the Fund's
performance during the year.

What makes these types of securities so attractive?

Securities backed by low-loan balance mortgages are attractive because interest
rates would have to drop substantially to entice homeowners to refinance these
small-balance mortgage loans. The manufactured housing mortgage-backed
securities tend to have stable prepayment rates in both up and down markets. So
these securities may offer attractive yields at reasonable prices, with lower
prepayment risk than other mortgage-backed securities.

How has your move into these securities affected the quality of the portfolio?

At year-end 1996, the portfolio's overall quality rating was triple-A by
Standard & Poor's,(S) the highest quality rating available. We seek to maintain
a broad mix of high-quality short-term debt securities in the portfolio to
provide liquidity and capital preservation for shareholders.

What do you see ahead for 1997?

We're not anticipating any negative news, but will keep an eye on the economy,
inflation, and interest rates. We don't believe that the Federal Reserve is
likely to make any major moves in the near future, and we feel that the economy
is growing at a sustainable rate. We'll continue to use our fundamental research
and quantitative analysis to identify opportunities for the portfolio as we seek
attractive total returns in the short-term debt market.

NOTES TO FINANCIAL STATEMENTS

- -------------------------------------------------------------------------------
NOTE 1--Organization and Business:
- -------------------------------------------------------------------------------
 
MainStay Institutional Funds Inc. (the "Company") was incorporated in the state
of Maryland on September 21, 1990 and commenced operations on January 2, 1991.
The Company is registered as an open-end management investment company under
the Investment Company Act of 1940, as amended, ("Investment Company Act"). As
of December 31, 1996 the Company has eleven separate investment portfolios:
EAFE Index Fund, Growth Equity Fund, Indexed Equity Fund, International Equity
Fund, Multi-Asset Fund, Value Equity Fund, Bond Fund, Indexed Bond Fund,
International Bond Fund, Money Market Fund and Short-Term Bond Fund
(individually or collectively referred to as a "Fund" or the "Funds").
 
  The International Bond Fund and the International Equity Fund commenced
operations on January 1, 1995.
 
  Each Fund currently offers two classes of shares as follows: Institutional
Class shares and Institutional Service Class shares. The Company has adopted a
Shareholder Services Plan with respect to the Institutional Service Class of
each Fund. The Institutional Class shares and Institutional Service Class
shares are substantially the same, except that the Institutional Service Class
shares bear the fees payable under the Shareholder Services Plan at an annual
rate of 0.25% of the average daily net assets of the outstanding Institutional
Service Class shares ("Shareholder Service Fee"). The distribution of
Institutional Service Class shares commenced on January 1, 1995.
 
  The investment objectives for each of the Funds of the Company are as
follows:
 
  The EAFE Index Fund seeks 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 Morgan Stanley Capital
International Europe, Australia and Far East ("EAFE") Index.
 
  The Growth Equity Fund seeks long-term growth of capital. Dividend income,
if any, is a consideration incidental to the Fund's objective of growth of
capital.
 
  The Indexed Equity Fund seeks 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 Standard & Poor's 500
Composite Stock Price Index.
 
  The International Equity Fund seeks long-term growth of capital by investing
in a portfolio consisting primarily of non-U.S. equity securities. Current
income is a secondary objective.
 
  The Multi-Asset Fund seeks to maximize total return, consistent with certain
percentage constraints on amounts allocated to each asset class, from a
combination of common stocks, fixed income securities, and money market
investments.
 
  The Value Equity Fund seeks maximum long-term total return from a
combination of capital growth and income. The Fund is not designed or managed
primarily to produce current income.
 
  The Bond Fund seeks to maximize total return, consistent with liquidity, low
risk to principal and investment in debt securities.
 
  The Indexed Bond Fund seeks to provide investment results that correspond to
the total return performance of fixed income securities in the aggregate, as
represented by the Salomon Brothers Broad Investment Grade Bond Index.
 
  The International Bond Fund seeks to provide total return by investing
primarily in a portfolio of non-U.S. (primarily government) debt securities.
 
  The Money Market Fund seeks to provide a high level of current income while
preserving capital and maintaining liquidity.
 
  The Short-Term Bond Fund seeks to maximize total return, consistent with
liquidity, preservation of capital and investment in short-term debt
securities.

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 Class of
shares of each Fund 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 of each Class of shares is determined
by taking the assets attributable to that Class, subtracting the liabilities
attributable to that Class, and dividing the result by the outstanding shares
of that Class.
 
The Money Market Fund seeks to maintain a net asset value of $1.00 per share,
although there is no assurance that it will be able to do so.
 
                                      (B)
 
SECURITIES VALUATION. Portfolio securities of the Money Market Fund are valued
at their 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.
 
  Portfolio securities of each of the other Funds are stated at value
determined (a) by appraising common and preferred stocks which are traded on
the New York Stock Exchange at the last sale price on that day or, if no sale
occurs, the mean between the closing bid price and asked price; (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 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 a pricing
agent selected by a Fund's investment adviser if such prices are deemed to be
representative of market values at the regular close of business of the New
York Stock Exchange; (e) by appraising debt securities at prices supplied by a
pricing agent selected by a Fund's investment adviser, whose prices reflect
broker/dealer supplied valuations and electronic data processing techniques if
those prices are deemed by a Fund's investment adviser to be representative of
market values at the regular close of business of the New York Stock Exchange;
(f) by appraising options and futures contracts at the last sale price on the
market where any such option or futures are principally traded; and (g) by
appraising all other securities and other assets, including over-the-counter
common and preferred stocks not quoted on the NASDAQ system, securities not
listed or traded on foreign exchanges whose operations are similar to the U.S.
over-the-counter market and debt securities for which prices are supplied by a
pricing agent but are not deemed by a Fund's investment 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 Board of Directors. Money Market
instruments held by the Funds with a remaining maturity of sixty days or less
are valued by the amortized cost method which 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.
 
  Events affecting the values of portfolio securities that occur between the
time their prices are determined and the close of the New York Stock Exchange
will not be reflected in the Funds' calculation of net asset values' unless a
Fund's investment adviser deems that the particular event would materially
affect such Fund's net asset value, in which case an adjustment will be made.
 
                                      (C)
 
FEDERAL INCOME TAXES. Each of the Funds 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 Fund within the allowable time limits. Therefore, no Federal income or
excise tax provision is required.
 
  Investment income received by a Fund from foreign sources may be subject to
foreign income taxes withheld at the source.

DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends are recorded on the ex-
dividend date. For the Money Market Fund, dividends are declared daily and
paid monthly. Each of the other Funds intends to declare and pay substantially
all of their net investment income and net realized gains no less frequently
than once a year. Income distributions and capital gain distributions are
determined in accordance with Federal income tax regulations which may differ
from generally accepted accounting principles.
 
                                      (F)
 
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. Discounts on securities, other than short-
term securities, purchased for all Funds are amortized on the constant yield
method over the life of the respective securities or, in the case of a
callable security, over the period to the first date of call.
 
                                      (G)
 
ORGANIZATION COSTS. Organization costs incurred for the International Bond
Fund and the International Equity Fund are being amortized over a maximum
period of 60 months beginning January 1, 1995, the date such Funds commenced
operations. In the event that any of the initial shares purchased by
affiliates of the Administrator 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.
 
                                      (H)
 
EXPENSES. Expenses with respect to any two or more Funds are allocated in
proportion to the net assets of the respective Funds when the expenses are
incurred except where allocations of direct expenses can otherwise fairly be
made.
 
  The investment income and expenses (other than expenses incurred under the
Shareholder Services Plan), and realized and unrealized gains and losses on
investments of a Fund are allocated to separate classes of shares based upon
their relative net assets on the date the income is earned or expenses and
realized and unrealized gains and losses are incurred.

                                      (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.
 
                                      (J)
 
FOREIGN CURRENCY TRANSACTIONS. The books and records of the Company are kept
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) income and expenses--at the date of such transactions.
 
  The assets and liabilities are presented at the exchange rates and market
values at the close of the period. The changes in net assets arising from
changes 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 transactions, net currency gains and
losses realized as a result of differences between the amounts of security
sale proceeds or purchase cost, dividends, interest and withholding taxes as
recorded on the Fund's books, and the U.S. dollar equivalent amount actually
received or paid. Net currency gains or losses from valuing such foreign
currency denominated assets and liabilities at period-end exchange rates are
reflected in unrealized foreign exchange gains or losses.
 
  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.

FORWARD CURRENCY CONTRACTS. A forward 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 reflect the market value of the
contract at the end of each day's trading. When the forward contract is
closed, the Fund records a realized gain or loss equal to the difference
between the proceeds from (or cost of) the closing transaction and the Fund's
basis in the contract. Forward currency contracts are used for hedging
purposes. (see Note 5).

                                      (L)
 
REPURCHASE AGREEMENTS. At the time the Funds enter into a repurchase
agreement, the value of the underlying security, including accrued interest,
will equal 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 Funds' custodian. In the case of repurchase agreements exceeding one day,
the market value of the underlying securities is monitored by pricing the
underlying securities daily.
 
  In the event of the bankruptcy of a counterparty, realization of the
collateral may be delayed or limited.
 
                                      (M)
 
FUTURES CONTRACTS. A futures contract is an agreement to purchase or sell a
specified quantity of an underlying instrument at a specified future date, 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 Fund 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 Fund records a realized gain or loss equal to
the difference between the proceeds from (or cost of) the closing transaction
and the Fund's basis in the contract. Futures contracts are used for hedging
purposes. (see Note 5).
 
                                      (N)
 
MORTGAGE DOLLAR ROLLS. A mortgage dollar roll ("MDR") is a transaction in
which a Fund sells mortgage backed securities ("MBS") from its portfolio to a
counterparty from whom it simultaneously agrees to buy a similar security on a
delayed delivery basis. The MDR transactions of a Fund are classified as
purchase and sale transactions. The securities sold in connection with the MDR
are removed from the portfolio and a realized gain or loss is recognized. The
 
                                      129

NOTES TO FINANCIAL STATEMENTS (Continued)

securities the Funds have agreed to acquire are included at market value in
the portfolio of investments and liability for such purchase commitments is
included as payables for investments purchased. The Fund maintains a
segregated account with its custodian containing securities from its portfolio
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 Fund at the end of the roll, while substantially similar,
could be inferior to what was initially sold to the counterparty.
 
                                      (O)
 
SECURITIES LENDING. The Fund may lend its securities to broker-dealers and
financial institutions. The loans are secured by collateral at least equal at
all times to the market value of the securities loaned. The Fund 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 Fund receives
compensation for lending its securities in the form of fees or it retains a
portion of interest on the investment of any cash received as collateral. The
Fund also continues 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 Fund. The
Fund did not engage in security lending during the year.

NOTE 5--Financial Investments:
- -------------------------------------------------------------------------------
 
The EAFE Index Fund's, International Equity Fund's, Multi-Asset Fund's and
International Bond Fund's 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 each Fund'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 each Fund's exposure at period end to credit loss in the event of a
counterparty's failure to perform its obligations.
 
  The EAFE Index Fund's and Multi-Asset Fund's use of forward foreign currency
exchange contracts are intended to minimize the risk of loss to the Fund from
adverse changes in the relationship between U.S. dollar and foreign
currencies. The International Equity Fund and International Bond Fund enter
into forward currency exchange contracts in order to protect against
uncertainty in the level of future foreign currency exchange rates.
 
   The EAFE Index Fund's, Indexed Equity Fund's, Multi-Asset Fund's and
Indexed Bond Fund's 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 each Fund's involvement in open futures positions. Risks
arise from possible imperfect correlation in movements in the price of futures
contracts, interest rates and the underlying hedged assets, and the possible
inability of counterparties to meet the terms of their contracts. However,
each Fund's activities in futures contracts are conducted through regulated
exchanges which minimize counterparty credit risks.
 
  The EAFE Index Fund and Indexed Equity Fund invests in stock index futures
contracts to maintain cash reserves while remaining fully invested, to
facilitate trading, or to reduce transaction costs. The Multi-Asset Fund has
entered into contracts for the future delivery of debt securities and invests
in stock index futures contracts to rebalance the Fund's portfolio composition
and risk profile to meet asset class constraints. The Indexed Bond Fund
invests in contracts for the future delivery of debt securities in order to
attempt to maintain cash reserves while remaining fully invested, to
facilitate trading, or to reduce transaction costs.

REPORT OF INDEPENDENT ACCOUNTANTS
- -------------------------------------------------------------------------------
 
To the Board of Directors and Shareholders of
MainStay Institutional Funds 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 EAFE Index Fund,
Growth Equity Fund, Indexed Equity Fund, International Equity Fund, Multi-
Asset Fund, Value Equity Fund, Bond Fund, Indexed Bond Fund, International
Bond Fund, Money Market Fund, and Short-Term Bond Fund (constituting MainStay
Institutional Funds Inc., hereafter referred to as the "Funds") at
December 31, 1996, the results of each of their operations for the year then
ended, the changes in each of their net assets for each of the two years then
ended 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 Funds' 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, 1996 by correspondence with the
custodian 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.
