PAST PERFORMANCE IS NO GUARANTEE OF FUTURE RESULTS. DUE TO
MARKET VOLATILITY, CURRENT PERFORMANCE MAY BE LESS THAN THAT
SHOWN. INVESTMENT RETURN AND PRINCIPAL VALUE WILL FLUCTUATE SO
THAT UPON REDEMPTION, SHARES MAY BE WORTH MORE OR LESS THAN
THEIR ORIGINAL COST.
Performance figures (through 1993 for MainStay Institutional
Value Equity Fund and MainStay Institutional Growth Equity Fund,
1996 for MainStay Institutional Asset Manager Fund, and 1998 for
MainStay Institutional International Equity Fund) reflect
certain fee waivers and/or expense limitations. As a result,
total return figures, which take into account these fee waivers
and/or expense limitations, may have been lower had they not
been in effect. The fee waivers and expense limitations are
voluntary and may be terminated at any time.
See prospectuses for more detailed information. The Funds'
prospectuses contain more information about advisory fees, other
expenses, and share classes. Please read them carefully before
you invest or send money.
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.

(+) The inception date of these Institutional Class shares is

(++) 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 12/31/94. Performance figures for the Sweep Shares
    Class, first offered to the public on 12/8/98, include the
    historical performance of the Service Class from the Service
    Class's inception (1/1/95) up to 12/7/98. Performance
    figures for these classes after these dates will vary based
    on differences in their expense structures.
(sec.) Performance figures and inception dates for the MainStay
    Institutional International Equity and MainStay
    Institutional International Bond Funds include the
    historical performance of the predecessor subaccounts, whose
    inception dates were 7/31/92 and 1/31/90, respectively.
    These Funds commenced operations on 1/1/95. MacKay Shields
    LLC, the Funds' investment subadvisor, served as investment
    advisor to the Separate Accounts, and the investment
    objectives, policies, restrictions, guidelines, and
    management style of the Separate Accounts were substantially
    similar to those of the respective Funds. Performance
    figures for the period prior to 1/1/95 have been calculated
    using the Separate Accounts' expense structures, which
    generally were higher than the expense structure of the
    Funds. The Separate Accounts were not registered under the
    Investment Company Act of 1940 (1940 Act) and therefore were
    not subject to certain investment restrictions imposed under
    the 1940 Act. If the Separate Accounts had been registered
    under the 1940 Act, the Separate Accounts' performance may
    have been adversely affected.
(II) MainStay Institutional Money Market Fund had an effective
    7-day yield of 6.41%, for the Institutional Class; 6.14% for
    the Service Class; 5.88% for the Sweep Shares Class; all as
    of 10/31/00. These yields reflect certain expense
    limitations. Had these expense limitations not been in
    effect, the effective 7-day yield and the current 7-day
    yield would have been 6.31% and 6.12%, respectively, for the
    Institutional Class; 6.05% and 5.87%, respectively, for the
    Service Class; and 5.78% and 5.62%, respectively, for the
    Sweep Shares Class. These expense limitations are voluntary
    and may be terminated or revised at any time.
    Investments in MainStay Institutional Money Market Fund are

    Corporation or any other government agency. Although the
    Fund seeks to preserve the value of your investment at $1.00
    per share, it is possible to lose money by investing in the

CHAIRMAN'S LETTER
--------------------------------------------------------------------------------

Report to shareholders for the period
November 1, 1999, through October 31, 2000.

The close of any fiscal year is a time for new beginnings. This is particularly
true at MainStay(R) Institutional Funds Inc., as we look forward to exciting new
developments in the months ahead.

On or about January 2, 2001, MainStay Institutional Funds will be renamed
Eclipse Funds Inc. At that time, our Fund family will be expanded with
additional Fund offerings. We will also lower our investment minimum to make our
Funds accessible to a wider range of investors. While the names of MainStay
Institutional Funds will change, their investment objectives, share classes, and
fee structures will remain the same--as will the portfolio managers responsible
for each Fund's day-to-day investment decisions.

During the 12 months ended October 31, 2000, investors weathered Y2K computer
concerns, rising interest rates, higher oil prices, a strengthening U.S. dollar,
and ongoing sensitivity to any signs of inflation. With slowing economic growth
and one of the tightest labor markets in history, the interplay of productivity,
wages, prices, and profits fueled ongoing stock market volatility, creating both
risks and opportunities.

After a smooth transition into the year 2000, technology stocks climbed to new
highs in early April, but rapidly retreated to more realistic levels. Reeling
from the sharp decline, technology investors were quick to respond to any
negative news through the end of October 2000. Large-cap stocks were also
volatile, with a number of peaks and valleys throughout the year. Disappointing
third-quarter earnings reports took a toll on large-cap equities in September
and October, but a late-October rally helped close the 12-month period on a
positive note.

The strength of the U.S. dollar negatively impacted most international stock
markets, with only a handful generating positive returns in U.S. dollar terms.
Rising interest rates and weak currencies hurt many international bond markets,
but several emerging bond markets benefited from rising oil prices and provided
strong returns.

The Federal Reserve raised the targeted federal funds rate four times in the 12
months ended October 31, 2000, for a total of 1.25%. Rising capital costs caused
corporate bonds to underperform, while a government buyback program and a
shifting yield curve created opportunities among Treasuries.

Each of the MainStay Institutional Funds uses a well-defined investment process
that's consistently applied across all market environments. This allows our
clients to focus on their long-range goals, while our portfolio managers pursue
competitive returns regardless of where the markets may move.

This annual report outlines the specific events that affected your MainStay
Institutional Funds during the 12 months ended October 31, 2000. We hope that
our focus on integrity, performance, and service have helped you pursue your
objectives with greater confidence and consistency during the past fiscal year.
As we look to the future, we hope our new name and new Funds will help expand
your options and opportunities for many years to come.

Sincerely,

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

Growth Equity Fund
--------------------------------------------------------------------------------

During the 12 months ended October 31, 2000, the U.S. stock market was buffeted
by a variety of forces. The Federal Reserve increased the targeted federal funds
rate four times--for a total of 1.25%--to slow the pace of the economy and keep
inflation in check. With the cost of capital and energy rising for corporations,
the market focused more closely on earnings projections and was particularly
unforgiving when companies failed to meet expectations.

Both "old-economy" stocks, such as health care, retailers, and utilities, and
"new-economy" technology stocks had their ups and downs in the 12 months ended
October 31, 2000, but the two seemed to move on different trajectories.
Technology stocks soared into 2000 and rose through early April, when a negative
inflation report and the Microsoft antitrust decision seemed to derail the
technology bandwagon. More defensive old-economy stocks picked up as technology
tumbled, and among large-cap equities, value outpaced growth through much of the
reporting period.

PERFORMANCE REVIEW

For the 12 months ended October 31, 2000, MainStay Institutional Growth Equity
Fund returned 12.24% for Institutional Class shares and 11.93% for Service Class
shares. Both share classes underperformed the 15.25% return of the average
Lipper(1) large-cap growth fund for the same period. During the 12-month period,
both share classes outperformed the 6.09% return of the S&P 500 Index.(2)

Both of the Fund's share classes were rated four stars overall out of 3,948
domestic equity funds by Morningstar(3) as of October 31, 2000. Both share
classes were rated four stars out of 3,948 domestic equity funds for the
three-year period then ended and four stars out of 2,458 domestic equity funds
for the five-year period then ended.

TECHNOLOGY

In the last two months of 1999, the Fund benefited from its overweighted
position in technology. Strong performers included Sun Microsystems, EMC, and
Oracle, all of which contributed positively to the Fund's performance throughout
the Fund's fiscal year. Careful security selection among technology stocks was a
strong contributor to overall performance, particularly in a year when many
technology names saw dramatic reversals. Although Texas Instruments and Intel
both provided positive returns for the Fund's fiscal year, both faced ups and
downs in an especially volatile market for technology stocks. Motorola's
continuing difficulties negatively impacted the Fund's performance, and in
September, we purchased shares of Hewlett-Packard for the Fund, expecting a
turnaround that has yet to occur.

CAPITAL GOODS AND CONSUMER CYCLICALS

The Fund's capital goods positions, including Corning and Tyco International,
contributed positively to performance during the Fund's fiscal year. The Fund
was also overweighted in consumer cyclicals early in 2000, benefiting from its
holdings in Time Warner, Circuit

City, and Harley-Davidson. As 2000 progressed, however, Circuit City floundered
and we sold the Fund's entire position. Although Time Warner lost much of the
ground that it had gained, we believe the stock continues to have potential.
Fortunately, Harley-Davidson's performance was particularly strong throughout
the Fund's fiscal year.

HEALTH CARE AND RELATED ISSUES

The health care sector had mixed results. Merck and Schering-Plough both
suffered early in 2000 as the market focused on technology stocks. When the
technology bubble burst, however, many investors turned their attention to
steady performers such as pharmaceuticals. Both stocks ended the Fund's fiscal
year in positive territory, with Merck staging a significant rally at the end of
October. Recent pharmaceutical stock purchases include generic, respiratory, and
cancer drug maker IVAX; time-release drug producer Andrx; and eye and skin care
specialist, Allergan. All three stocks have increased in value since their
purchase.

Medical device manufacturer Medtronic had a positive impact on the Fund's
performance, climbing significantly throughout the year. Guidant also had
positive results for the Fund's fiscal year, despite a significant drop in
October, when analysts reevaluated the company's coronary stent business. After
peaking in early March, PE Biosystems followed the technology trend downward,
but made a substantial recovery, to close the Fund's fiscal year at more than
three times its price on November 1, 1999.

OTHER SECTORS

The Fund benefited from a heavily overweighted position in utilities during the
third calendar quarter of 2000, with AES and Enron providing strong performance.
Even with weaker performance in October, both stocks ended the reporting period
at more than twice their price on November 1, 1999. General Electric, one of the
Fund's ten largest holdings as of October 31, 2000, also provided positive
results for the Fund.

On the whole, telecommunications did not fare as well as other sectors. The Fund
sold AT&T Wireless and Global Crossing and reduced its position in Nextel.
WorldCom and Voicestream provided modest gains, but the Fund's purchase of
Nortel Networks had a negative impact on performance, when its stock price
dropped at the end of the reporting period on disappointing earnings news.
Communications equipment companies also had mixed results, with Cisco Systems
rising and Nokia holding its own, while Tellabs had a difficult year. The Fund
sold Lucent Technologies in the midst of the stock's extended decline.

Among retailers, Kohl's and CVS provided positive results for the Fund, while
some others faced setbacks. Home Depot dropped precipitously in early October
after an earnings warning, but we continue to hold the stock, believing the
price adjustment was excessive, based on the company's still-solid underlying
business fundamentals. Staples, on the other hand, saw continued price erosion,
and we reduced the Fund's position to put the assets to more productive use.

Finally, the Fund benefited from a substantial position in Citigroup and
selective new purchases in the financial services sector, including Household
International, MBNA, and Mellon Financial.

LOOKING AHEAD

With signs that the economy is beginning to slow and that inflation may remain
subdued,

                                        4

--------------------------------------------------------------------------------

we are optimistic for growth prospects in the coming months. We believe the Fund
is appropriately overweighted in technology stocks and utilities and will
continue to seek investment opportunities as an election year ends and a new
administration takes the helm.

No matter what the economy or markets may bring, the Fund will continue to seek
long-term growth of capital, with dividend income, if any, remaining an
incidental consideration.

Indexed Equity Fund
--------------------------------------------------------------------------------

During the 12 months ended October 31, 2000, the U.S. stock market was buffeted
by a variety of forces. The Federal Reserve increased the targeted federal funds
rate four times--for a total of 1.25%--to slow the pace of the economy and keep
inflation in check. With the cost of capital rising for corporations, the market
focused more closely on earnings projections and was particularly unforgiving
when companies failed to meet expectations.

Both "old-economy" stocks, such as health care, retailers, and utilities, and
"new-economy" technology stocks had their ups and downs in the 12 months ended
October 31, 2000, but the two seemed to move on different trajectories.
Technology stocks soared into 2000 and rose through early April, when a negative
inflation report and the Microsoft antitrust decision seemed to derail "dot.com"
fever. More defensive old-economy stocks picked up as technology tumbled, and
among large-cap equities, value outpaced growth through much of the reporting
period.

PERFORMANCE REVIEW

For the 12 months ended October 31, 2000, MainStay Institutional Indexed Equity
Fund returned 5.98% for Institutional Class shares and 5.72% for Service Class
shares. Both share classes outperformed the 5.48% return of the average
Lipper(1) S&P 500 Index objective fund for the same period. During the 12-month
period, both share classes underperformed the 6.09% return of the S&P 500
Index.(2) Investors should expect the Fund to lag the Index somewhat, since the
Fund faces real-world fees and expenses that a hypothetical index does not.

Both of the Fund's share classes were rated four stars overall out of 3,948
domestic equity funds by Morningstar(3) as of October 31, 2000. Both share
classes were rated four stars out of 3,948 domestic equity funds for the
three-year period then ended and four stars out of 2,458 domestic equity funds
for the five-year period then ended.

BEST AND WORST PERFORMERS

During the 12 months ended October 31, 2000, several "old-economy" stock sectors
had the highest total returns in the S&P 500 Index, with health-related
industries leading the pack. Hospital management returned 76.9%, health
care--HMOs advanced 74.3%, and retail stores--drugs returned 68.8%. Other top
performing sectors included food and health distributors, which advanced 61.4%,
and investment banks/brokerage, which rose 58.3%.

The weakest sectors in the Index included containers (-60.4%), office equipment
(-56.3%), telecommunications--long distance (-54.8%), and photography and
imaging (-36.4%).

PAST PERFORMANCE IS NO GUARANTEE OF FUTURE RESULTS. DUE TO MARKET VOLATILITY,
CURRENT PERFORMANCE MAY BE LESS THAN THAT SHOWN. INVESTMENT RETURN AND PRINCIPAL
VALUE WILL FLUCTUATE SO THAT UPON REDEMPTION, SHARES MAY BE WORTH MORE OR LESS
THAN THEIR ORIGINAL COST.
The Fund's net asset value will fluctuate and you could lose money by investing
in the Fund. The Fund may invest in derivatives, which may increase the
volatility of the Fund's net asset value and may result in a loss to the Fund.

    returns (if applicable) in excess of 90-day Treasury bill returns, and a
    risk factor that reflects fund performance below 90-day Treasury bill
    returns. The Overall Morningstar Rating(TM) represents a weighted average of
    the three-, five-, and 10-year (if applicable) risk-adjusted performance.
    The top 10% of funds in a broad asset class receive five stars, the next
    22.5% receive four stars, the middle 35% receive three stars, the next 22.5%
    receive two stars, and the bottom 10% receive one star. Past performance is
    no guarantee of future results.

In terms of overall impact on the Index taking both returns and weightings into
account, the best-performing sectors were computers--networking,
computers--peripherals, diversified financial companies, electrical equipment,
and multi-line insurance companies. Taking both returns and weightings into
account, long-distance telephone companies were the weakest-performing sector,
followed by communication equipment, general merchandise retailers, computer
software/services, and money-center banks.

Advances and declines among individual companies were considerably more
dramatic. Network Appliance (+543.2%) was a top-performer, with an expanding
market for its Internet and intranet file-delivery systems. Siebel Systems
produces customer relationship software and provided an outstanding 282.2%
return during the Fund's fiscal year. Life sciences specialist PE
Corporation--PE Biosystems Group (+260.7%) and integrated circuit and digital
equipment manufacturer Broadcom (+248.0%) rounded out the top five companies in
the Index in terms of total return.

Based on total return alone, the worst-performing stocks in the S&P 500 for the
12-month period were Armstrong Holdings (-92.3%) and Owens-Illinois (-75.2%),
both of which suffered from concerns over asbestos litigation. W. R. Grace
(-74.5%), Compuware (-71.7%), and Conseco (-71.5%), were also among the weakest
stocks in the Index in terms of total return.

Taking both returns and weightings into account, the companies with the greatest
positive impact on the performance of the Index during the reporting period were
Oracle, EMC, General Electric, American International Group, and Citigroup. On a
weighted return basis, the companies that detracted most from the performance of
the Index during the Fund's fiscal year were Microsoft, Lucent Technologies,
AT&T, WorldCom Inc., and Wal-Mart Stores.

INDEX CHANGES

From time to time, Standard & Poor's adjusts the S&P 500 Index to reflect
changes in the companies and industries that impact our economy. There were two
significant additions to the S&P 500 Index during the reporting period. Yahoo!,
a global Internet media company, was added on December 8, 1999, as the 30th
largest member of the Index at that time. JDS Uniphase, a company that designs,
develops, manufactures, and distributes products for the fiberoptic
communications market, joined the Index on July 26, 2000, as the 29th largest
member of the Index on that date.

These weren't the only changes to the Index during the reporting period. Over 40
stocks were added to the Index and more than 40 were deleted between November 1,
1999, and October 31, 2000, either to better reflect the makeup of our economy
or because of mergers, acquisitions, bankruptcies, or other corporate actions.

LOOKING AHEAD

Despite a generally favorable economic outlook, corporations now have to contend
with high oil prices, higher borrowing costs, and extremely low unemployment.
Having recently seen several earnings disappointments, we anticipate continued
uncertainty, ongoing volatility, and trading within a range, at least for a
while.

Whatever the markets or the economy may bring, the Fund will continue to seek to
provide investment results that correspond to the total-return performance
(reflecting reinvestment of dividends) of common stocks in the aggregate, as
represented by the S&P 500 Index.

PAST PERFORMANCE IS NO GUARANTEE OF FUTURE RESULTS. DUE TO MARKET VOLATILITY,
CURRENT PERFORMANCE MAY BE LESS THAN THAT SHOWN. INVESTMENT RETURN AND PRINCIPAL
VALUE WILL FLUCTUATE SO THAT UPON REDEMPTION, SHARES MAY BE WORTH MORE OR LESS
THAN THEIR ORIGINAL COST.

(*) Total returns shown herein include the change in share price and
    reinvestment of capital gain distributions and dividends, and, for the
    Service Class shares, include the service fee of .25% on an annualized basis
    of the average daily net asset value of the Service Class shares.

(+) 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 12/31/94. Performance figures for these
    two classes will vary after this date based on differences in their expense
    structures.

(++) Lipper Inc. is an independent fund performance monitor. Results are based
     on total returns with capital gain and dividend distributions reinvested.

(sec.) "S&P 500(R)" is a trademark of The McGraw-Hill Companies, Inc. The S&P
       500 is an unmanaged index and is widely regarded as the standard for
       measuring large-cap U.S. stock market performance. Returns assume the
       reinvestment of all income and capital gain distributions. An investment
       cannot be made directly into an index.

Value Equity Fund
--------------------------------------------------------------------------------

During the 12 months ended October 31, 2000, the U.S. stock market was buffeted
by a variety of forces. The Federal Reserve increased the targeted federal funds
rate four times--for a total of 1.25%--to slow the pace of the economy and keep
inflation in check. With the cost of capital rising for corporations, the market
focused more closely on earnings projections and was particularly unforgiving
when companies failed to meet expectations.

Both "old-economy" stocks, such as health care, retailers, and utilities, and
"new-economy" technology stocks had their ups and downs in the 12 months ended
October 31, 2000, but the two seemed to move on different trajectories.
Technology stocks soared into 2000 and rose through early April, when a negative
inflation report and the Microsoft antitrust decision seemed to derail "dot.com"
fever. More defensive old-economy stocks picked up as technology tumbled, and
among large-cap equities, value outpaced growth through much of the reporting
period. Smaller value stocks also did well in the third calender quarter of
2000. Wherever the markets may turn, recent experience underscores the soundness
of including value disciplines in a well-diversified portfolio.

PERFORMANCE REVIEW

For the 12 months ended October 31, 2000, MainStay Institutional Value Equity
Fund returned 11.31% for Institutional Class shares and 11.00% for Service Class
shares. Both share classes outperformed the 10.94% return of the average
Lipper(1) multi-cap value fund for the same period. During the 12-month period,
both share classes outperformed the 5.52% return of the Russell 1000 Value
Index.(2)

UNDERWEIGHTING TECHNOLOGY

One reason for the Fund's strong performance was its underweighted position in
technology relative to the S&P 500 throughout the reporting period. While that
hurt performance, as technology stocks rose to speculative highs early in 2000,
it helped the portfolio throughout the rest of the reporting period.

Only a few technology stocks met the Fund's value disciplines. Hard disc
manufacturer Seagate Technologies and software and services company Ceridian
both had a positive impact on the Fund's performance, and the Fund took profits
in these issues in the second half of its fiscal year. We purchased shares of
Electronic Data Systems for the Fund in the second and third calendar quarters
of 2000, as the stock was recovering from a precipitous price drop in June. This
purchase also had a positive impact on the Fund's performance.

Other technology-related holdings, including Motorola, Unisys, and IBM, had a
negative impact on performance. The Fund purchased Apple Computer near the end
of October, after an earnings warning caused a dramatic sell-off that brought
the price within the Fund's value disciplines.

Telecommunications stocks, which have close ties to technology holdings, did not
fulfill their promise in the 12 months ended October 31, 2000. AT&T and WorldCom
had particularly difficult years, CenturyTel declined, and Verizon
Communications ended both September and October with impressive rallies, but

failed to fully recover the ground the stock had lost since November 1, 1999.

PAST PERFORMANCE IS NO GUARANTEE OF FUTURE RESULTS. DUE TO MARKET VOLATILITY,
CURRENT PERFORMANCE MAY BE LESS THAN THAT SHOWN. INVESTMENT RETURN AND PRINCIPAL
VALUE WILL FLUCTUATE SO THAT UPON REDEMPTION, SHARES MAY BE WORTH MORE OR LESS
THAN THEIR ORIGINAL COST. THE FUND'S NET ASSET VALUE WILL FLUCTUATE AND YOU
COULD LOSE MONEY BY INVESTING IN THE FUND.

ENERGY-RELATED HOLDINGS

The rising price of oil also contributed positively to the Fund's performance,
as a number of energy-related issues provided outstanding results. Among the
Fund's best-performing energy stocks were Coastal, Dynegy, and Valero Energy.
The Fund took some profits in the latter two names, but retained positions in
all three stocks, given their continuing potential. Tosco, Sunoco, and
Burlington Resources all contributed positively to performance, but Texaco and
Chevron detracted. Niagara Mohawk Holdings is a utility stock that languished
for much of the Fund's fiscal year, but provided a positive return after the
company agreed to an acquisition by a British transmission company.

RETAIL, CONSUMER, AND HEALTH CARE HOLDINGS

Retailers and consumer-related stocks were mixed, with Office Depot and Sears
recording losses, while McDonald's and The Gap provided positive returns for the
Fund since their purchase during the year. Proctor & Gamble, Kimberly-Clark,
Ralston-Purina, and H.J. Heinz all had a positive impact on performance, as did
Becton, Dickinson, whose consumer products range from ACE bandages to insulin
syringes.

Some other health care stocks performed well for the Fund, including Abbott
Laboratories and Tenet Healthcare. The Fund sold its position in Health
Management Associates at a gain for the year. The lackluster performance of
Manor Care led us to sell the Fund's entire position in the second half of the
fiscal year. Although the sale had a negative impact on performance, it allowed
us to put the assets to more productive use.

FINANCIAL POSITIONS

The Fund's decision to overweight financial stocks proved beneficial in a rising
interest rate environment. The Fund's positions in Citigroup, Washington Mutual,
and American General all contributed positively to performance, as did insurance
company holdings MGIC Investment and Allstate.

During the second half of its fiscal year, the Fund purchased Lincoln National,
J.P. Morgan, PNC Financial Services Group, and Goldman Sachs Group, all of which
also contributed to the Fund's positive results. The Fund sold its position in
AXA Financial, at a gain during the year, but held onto FleetBoston Financial,
despite slightly disappointing performance.

OTHER NOTEWORTHY HOLDINGS

Despite considerable volatility, Air Products and Chemicals had a strong showing
for the 12 months ended October 31, 2000. Defense contractor General Dynamics
also contributed positively to the Fund's performance, with a sharp and
sustained recovery from its decline in the early months of 2000. American
Standard, known for its plumbing and air conditioning products and automotive
braking systems, also had a positive impact on the Fund's results during the
reporting period.

Other stocks didn't fare as well. International Paper declined throughout much
of the year, and the Fund sold its packaging holdings to put those assets to
more productive use. Industrial company Ingersoll-Rand had disappointing
performance as interest rates rose and the company integrated acquisitions and
planned divestitures. We continue to hold the stock, believing the market has
undervalued its long-term potential.

Finally, Honeywell International, which makes a variety of aerospace,
automation, power, and transportation products, dropped in January and again in
June, but staged a substantial recovery in mid-October 2000 when merger talks
with United Technologies were confirmed. Even so, the stock was down slightly
for the year.

LOOKING AHEAD

We remain optimistic about the potential for value equities, particularly as
rising interest rates and a slowing economy continue to impact the appeal of
growth stocks. We continue to believe that our disciplined, research-driven
stock selection process will be critical in distinguishing value opportunities
from situations where stocks are likely to remain low priced. While the specter
of inflation and rising interest rates continues, we believe the Federal Reserve
may hold off any further moves for the remainder of 2000.

Whatever the markets or the economy may bring, the Fund will continue to seek
maximum long-term total return from a combination of capital growth and income.

PAST PERFORMANCE IS NO GUARANTEE OF FUTURE RESULTS. DUE TO MARKET VOLATILITY,
CURRENT PERFORMANCE MAY BE LESS THAN THAT SHOWN. INVESTMENT RETURN AND PRINCIPAL
VALUE WILL FLUCTUATE SO THAT UPON REDEMPTION, SHARES MAY BE WORTH MORE OR LESS
THAN THEIR ORIGINAL COST.

 (*) Total returns shown herein include the change in share price and
     reinvestment of capital gain distributions and dividends, and, for the
     Service Class shares, include the service fee of .25% on an annualized
     basis of the average daily net asset value of the Service Class shares.

 (+) 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 12/31/94. Performance figures for these
     two classes will vary after this date based on differences in their expense
     structures.

 (++) Lipper Inc. is an independent fund performance monitor. Results are based
      on total returns with capital gain and dividend distributions reinvested.

 (sec.) The Russell 1000 Value Index is an unmanaged index that measures the
        performance of those Russell 1000 companies with lower price-to-book
        ratios and lower forecasted growth values. The Russell 1000 is an
        unmanaged index that measures the performance of the 1,000 largest
        companies in the Russell 3000(R) Index, which, in turn, is an unmanaged
        index that includes the 3,000 largest U.S. companies based on total
        market capitalization. Returns reflect reinvestment of all dividends and
        capital gains. An investment cannot be made directly into an index.

Asset Manager Fund
--------------------------------------------------------------------------------

During the 12 months ended October 31, 2000, the U.S. stock market was buffeted
by a variety of forces. The Federal Reserve increased the targeted federal funds
rate four times--for a total of 1.25%--to slow the pace of the economy and keep
inflation in check. With the cost of capital rising for corporations, the market
focused more closely on earnings projections and was particularly unforgiving
when companies failed to meet expectations.

Domestic bonds and cash investments did relatively well during the 12 months
ended October 31, 2000. Rising short-term rates led to an inverted yield curve,
creating a variety of new opportunities for bond investors. In the third
calendar quarter of 2000, the bond market rallied as economic evidence indicated
that the Federal Reserve was becoming less likely to continue tightening the
money supply.

Given the strength of the U.S. dollar versus most other currencies,
international stock markets had mixed results in U.S. dollar terms. Canada and
Hong Kong were particularly strong, while Japan, Australia, and the United
Kingdom provided negative U.S. dollar returns over the 12-month period.

PERFORMANCE REVIEW

For the 12 months ended October 31, 2000, MainStay Institutional Asset Manager
Fund returned 11.18% for Institutional Class shares and 10.96% for Service Class
shares. Both share classes outperformed the 9.34% return of the average
Lipper(1) flexible portfolio fund for the same period. During the 12-month
period, the S&P 500 Index(2) returned 6.09%, the Salomon Smith Barney Broad
Investment Grade (BIG) Bond Index(3) returned 7.28%, and three-month Treasury
bills returned 5.84%.

Both of the Fund's share classes were rated four stars overall out of 3,948
domestic equity funds by Morningstar(4) as of October 31, 2000. Both share
classes were also rated four stars out of 3,948 domestic equity funds for the
three-year period then ended and four stars out of 2,458 domestic equity funds
for the five-year period then ended.

ALLOCATION DECISIONS

The Fund uses a tactical asset-allocation model that incorporates several
economic and technical factors to determine the appropriate asset mix within
allocation constraints outlined in the prospectus. During the reporting period,
the Fund was able to invest in U.S. real estate investment trusts, also known as
REITs, which were the Fund's best-performing asset class in the second calendar
quarter of 2000 and contributed positively to the Fund's performance for the
12-month period ended October 31, 2000.

During the reporting period, the Fund's allocations to Canada and Hong Kong
contributed to its strong performance relative to its peers. With a 29.11% U.S.
dollar return,(5) Canada was the strongest international market in which the
Fund invested. This was followed by Hong Kong (+13.94%), France (+6.93%), and
Germany (+3.60%), all in U.S. dollar terms. International markets in which the
Fund earned negative U.S. dollar returns during the reporting period included
Japan (-15.25%), United Kingdom (-7.11%), and Australia (-7.73%).

The Fund's asset allocation model kept common stock investments between 45% and
50% of net assets through most of the Fund's fiscal year. Bond allocations
varied slightly, with a higher allocation to U.S. government and agency bonds
going into 2000 than later in the year. At the end of 1999, the Fund had
approximately 5% of its net assets in mortgage-backed securities, which declined
to 4.8% by the end of the first calendar quarter of 2000, but later rose to 6.9%
of net assets at the end of June 2000, and did not stray far from that level
through the remainder of the Fund's fiscal year.

LOOKING AHEAD

Given recent indicators, we believe that corporate profit growth may be slower
going forward. Tightening moves by the Federal Reserve and other world central
banks have begun to impact global demand. Higher energy costs and tight labor
markets are also putting pressure on corporate profitability.

It looks as though the Federal Reserve may pull off the perfect "soft landing"
for the U.S. economy, by slowing economic growth just enough to cut off
inflationary pressures, while keeping unemployment stable. In light of this
trend, we believe we may have seen the last of Federal Reserve moves to increase
interest rates in 2000. We expect equity markets to continue to be somewhat
choppy and trade in a range through the end of the calendar year, and we believe
that U.S. markets for income securities should continue to hold their own in
this environment.

Whatever the economy or the markets may bring, the Fund will continue to seek 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.

PAST PERFORMANCE IS NO GUARANTEE OF FUTURE RESULTS. DUE TO MARKET VOLATILITY,
CURRENT PERFORMANCE MAY BE LESS THAN THAT SHOWN. INVESTMENT RETURN AND PRINCIPAL
VALUE WILL FLUCTUATE SO THAT UPON REDEMPTION, SHARES MAY BE WORTH MORE OR LESS
THAN THEIR ORIGINAL COST.

(*) Total returns shown herein include the change in share price and
    reinvestment of capital gain distributions and dividends, and, for the
    Service Class shares, include the service fee of .25% on an annualized basis
    of the average daily net asset value of the Service Class shares.

(+) 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 12/31/94. Performance figures for these
    two classes after this date will vary based on differences in their expense
    structures.

(++) Lipper Inc. is an independent fund performance monitor. Results are based
     on total returns with capital gain and dividend distributions reinvested.

(sec.) The Salomon Smith Barney Broad Investment Grade (BIG) Bond Index is an
       unmanaged index that is considered to be representative of the U.S. bond
       market. Returns reflect the reinvestment of all income and capital gains.
       An investment cannot be made directly into an index.

International Equity Fund
--------------------------------------------------------------------------------

For the 12 months ended October 31, 2000, international equity markets generally
provided disappointing returns for U.S. investors. Several markets in the
Pacific Rim provided negative results in local currency terms, with even weaker
returns when those figures were translated into U.S. dollars.

In local currency terms, performance was considerably better in Australia,
Canada, and major European markets, with many nations providing double-digit
returns for the reporting period. Yet most of these returns were considerably
reduced--and many turned negative--when the strength of the U.S. dollar was
taken into account.

During the year, Japan tried to jump-start its economy with a fiscal stimulus
package. Europe continued its corporate and economic restructuring, and central
banks around the world continued to tighten money supplies to keep economic
growth and inflation at reasonable levels. Several markets remained volatile and
uncertain through much of the year, and various sectors--including technology
and telecommunications--experienced setbacks, as value stocks and "old-economy"
sectors regained ground they had previously lost. For U.S. investors, however,
the big story during the year ended October 31, 2000, wasn't about economic
policy, industry trends, or investment styles. Rather it was the strength of the
U.S. dollar and the impact it had on international stock returns.

PERFORMANCE REVIEW

For the 12 months ended October 31, 2000, MainStay Institutional International
Equity Fund returned -9.44% for Institutional Class shares and -9.62% for
Service Class shares. Both share classes underperformed the 2.70% return of the
average Lipper(1) international fund for the same period. During the 12-month
period, both share classes also underperformed the -2.90% return of the EAFE
Index.(2)

Belgium was the worst-performing market in which the Fund invested, returning
-18.10% in U.S. dollar terms during the Fund's fiscal year,(3) followed by
Ireland (-13.73%), Singapore (-12.98%), and Japan (-11.61%). Despite positive
local currency returns, stocks in the U.K., Switzerland, and Australia also
provided negative returns in U.S. dollar terms for the reporting period.

JAPANESE AND PACIFIC EQUITIES

Anticipating positive results from Japan's fiscal reform package, the Fund
strengthened its allocation to Japanese equities early in 2000. The move had an
unfortunate effect as the Japanese market continued to lose ground. We primarily
focused the Fund's holdings among large companies with worldwide distribution,
such as Sony, NEC, and TDK, which generally managed to hold their ground in a
declining Japanese market. We also hoped to take advantage of consolidation
potential in the pharmaceutical industry and sought promising opportunities
among local companies poised to benefit from industry expansion and the nation's
economic recovery.

While we believe our selections were appropriate, in the second calendar quarter
of 2000, it became clear that more time would be needed for the stock market to
embrace Japan's economic and fiscal reforms. The Fund has reduced its Japanese
holdings from an overweighted to an underweighted position relative to the
benchmark. We have continued to evaluate negative market sentiment, looking for
possible trouble spots as well as potential opportunities.

PAST PERFORMANCE IS NO GUARANTEE OF FUTURE RESULTS. DUE TO MARKET VOLATILITY,
CURRENT PERFORMANCE MAY BE LESS THAN SHOWN. INVESTMENT RETURN AND PRINCIPAL
VALUE WILL FLUCTUATE SO THAT UPON REDEMPTION, SHARES MAY BE WORTH MORE OR LESS
THAN THEIR ORIGINAL COST.
Investments in foreign securities may be subject to greater risks than domestic
investments. These risks include currency fluctuations, changes in U.S. or
foreign tax or currency laws, and changes in monetary policies and economic and
political conditions in foreign countries.

For the 12 months ended October 31, 2000, Singapore provided negative returns in
both local currency and U.S. dollar terms. Australia continued to benefit from
its commodity-rich economy and saw tourism revenues increase dramatically during
the Olympics. Unfortunately, currency translations hurt equity returns, with
Australian stocks providing +16.39% in local currency terms but -5.36% in U.S.
dollar terms. The Fund's investments in Singapore and Australia detracted from
performance during the Fund's fiscal year.

EUROPEAN RESULTS

With the U.S. dollar rising strongly against the euro for most of the year, even
the strongest core European markets saw their returns dramatically reduced for
U.S. investors. In France, U.S. dollar returns (+7.06%) were less than one
quarter of returns in the local currency, and in Germany, U.S. dollar returns
(+1.09%) were less than one-twentieth of local returns.

Scandinavian markets, including Finland (+25.29%), Denmark (+14.92%), Norway
(+11.46%), and Sweden (+11.08%), were the European leaders in U.S. dollar terms,
followed by Italy at 11.06%. The Fund benefited from its investments in each of
these countries. The Fund also favored Portugal and Ireland, which showed signs
of better-than-average economic growth. While both markets had positive results
in local currency terms, Portugal was down 8.19% and Ireland lost 13.73% in U.S.
dollar terms, which detracted from the Fund's performance.

In October, Nokia reported extremely strong third-quarter results, well ahead of
market expectations. DaimlerChrysler's third-quarter figures, on the other hand,
were disappointing, with operating profits down 79% from the previous year.
Fortunately, the Fund had underweighted DaimlerChrysler relative to the EAFE
Index. Throughout Europe, the Fund has reduced its technology weightings in
favor of banks.

LOOKING AHEAD

While the Fund suffered from its exposure to the euro, we believe that the stage
has been set for the U.S. dollar to plateau and weaken over the coming quarters.
Structural reform in Europe, concerted central-bank intervention, and
prospective Federal Reserve easing alongside further European tightening bode
well for the euro and currencies in Europe's periphery. We believe most major
foreign currencies are extremely undervalued relative to the U.S. dollar and
anticipate that continued strength in the U.S. stock market could trigger a
significant dollar correction.

The recent style shift from growth to value stocks has increased our interest in
"old-economy" equities, and we will continue to seek opportunities in
established companies that we believe have solid fundamentals and strong
long-term potential. We also believe that companies with potential for
consolidation, cost reduction, or organic growth are likely to continue to
attract investor attention in any market environment.

Whatever the markets, currencies, or global economy may bring, the Fund will
continue to seek long-term growth of capital by investing in a portfolio
consisting primarily of non-U.S. equity securities, with current income as a
secondary objective.

The inception date of MainStay Institutional International Equity Fund was
1/1/95.

(*)    The inception date of MainStay Institutional International Equity Fund's
       predecessor separate account ("Separate Account") is 7/31/92. Performance
       figures, and, in the case of the graphs reflecting the investment of
       $250,000, investment results include the historical performance of the
       Separate Account for the period prior to MainStay Institutional
       International Equity Fund's commencement of operations on 1/1/95. MacKay
       Shields LLC, MainStay Institutional International Equity Fund's
       subadvisor, served as investment advisor to the Separate Account, and the
       investment objective, policies, restrictions, guidelines, and management
       style of the Separate Account were substantially similar to those of
       MainStay Institutional International Equity Fund. Performance figures and
       investment results for the period prior to 1/1/95 have been calculated
       using the Separate Account's expense structure, which generally was
       higher than the expense structure of MainStay Institutional International
       Equity Fund. The Separate Account was not registered under the Investment
       Company Act of 1940 ("1940 Act") and therefore was not subject to certain
       investment restrictions imposed under the 1940 Act. If the Separate
       Account had been registered under the 1940 Act, the Separate Account's
       performance and investment results may have been adversely affected.

(+)    Total returns shown herein include the change in share price and
       reinvestment of capital gain distributions and dividends, and, for the
       Service Class shares, include the service fee of .25% on an annualized
       basis of the average daily net asset value of the Service Class shares.

(++)   Lipper Inc. is an independent fund performance monitor. Results are based
       on total returns with capital gain and dividend distributions reinvested.

(sec.) The Morgan Stanley Capital International Europe, Australasia, and Far
       East Index--The EAFE Index--is an unmanaged index generally considered to
       be representative of the international stock market. Returns assume the
       reinvestment of all dividend and capital gain distributions. An
       investment cannot be made directly into an index.

EAFE Index Fund
--------------------------------------------------------------------------------

For the 12 months ended October 31, 2000, international equity markets provided
mixed results in both local currency and U.S. dollar terms. Early in 2000, Japan
launched a fiscal stimulus package that failed to jumpstart the Japanese stock
market or dramatically strengthen the yen. This may help explain why the only
nations in the MSCI EAFE Index(1) that provided negative total returns in local
currency terms were in the Pacific Rim.

Europe saw strong total returns across the board in local currency terms, with
Scandinavian nations leading the way. Several core European markets also
provided strong returns in their respective local currencies. When those returns
were translated into U.S. dollars, however, the results were considerably lower.
In many cases, currency translation turned positive local returns into negative
results for U.S. investors.

Central banks throughout Europe continued to adjust interest rates in an effort
to keep inflation in check and economic growth on track. Unfortunately, the
euro, like the yen, the pound sterling, and most other major currencies,
continued to languish throughout most of the year, showing little promise of
changing direction. The strength of the U.S. dollar left many international
equity investors with a negative overall return in U.S. dollar terms.

PERFORMANCE REVIEW

For the 12 months ended October 31, 2000, MainStay Institutional EAFE Index Fund
returned -3.52% for Institutional Class shares and -3.63% for Service Class
shares. Both share classes underperformed the 2.70% return of the average
Lipper(2) international fund over the same period. Both share classes also
underperformed the -2.90% return of the MSCI EAFE Index for the 12 months ended
October 31, 2000. Investors should expect the Fund to lag the Index by a small
margin, since the Fund faces real-world fees and expenses that a hypothetical
index does not.

POSITIVE CONTRIBUTORS

Taking both weightings and total returns into account, France, Finland, and
Italy made the greatest positive contribution to the performance of the EAFE
Index during the 12-month reporting period. The strong performance of French
stocks was led by the television and telecommunications industries, including
companies such as Canal Plus (+108%) and Alcatel (+95%), both in U.S. dollar
terms. Finland's advance was driven by Nokia, which gained 48% in U.S. dollar
terms. Italy's strong performance was driven by its telecommunications industry
and in particular by companies like TIM Spa (+36%) and Telecom Italia (+33%),
both in U.S. dollar terms.

NEGATIVE PERFORMERS

Performance wasn't uniformly strong, however. Stocks in Japan, the United
Kingdom, and Switzerland took the greatest toll on the Fund's performance during
the 12-month reporting period. Japan declined 11.61% in U.S. dollar terms,
reflecting investor apprehension with respect to the Japanese economy. Both the
United Kingdom and Switzerland posted positive returns in local currency terms,
but given the relative weakness of their currencies, both provided negative
returns in U.S. dollar terms.

--------------------------------------------------------------------------------
PAST PERFORMANCE IS NO GUARANTEE OF FUTURE RESULTS. DUE TO MARKET VOLATILITY,
CURRENT PERFORMANCE MAY BE LESS THAN THAT SHOWN. INVESTMENT RETURN AND PRINCIPAL
VALUE WILL FLUCTUATE SO THAT UPON REDEMPTION, SHARES MAY BE WORTH MORE OR LESS
THAN THEIR ORIGINAL COST.
Investments in foreign securities may be subject to greater risks than domestic
investments. These risks include currency fluctuations, changes in U.S. or
foreign tax or currency laws, and changes in monetary policies and economic and
political conditions in foreign countries.
(1) The Morgan Stanley Capital International Europe, Australasia, and Far East
    Index--the EAFE Index--is an unmanaged index generally considered to be
    representative of the international stock market. Returns assume the
    reinvestment of all income and capital gain distributions. An investment
    cannot be made directly into an index.
(2) Lipper Inc. is an independent fund performance monitor. Results are based on
    total returns with capital gain and dividend distributions reinvested.

LOOKING AHEAD

The stock markets of the EAFE Index continue to be impacted by the strength of
the U.S. dollar relative to most other major currencies. They have also felt the
effects of a turbulent technology sector and increased concerns over corporate
earnings. While oil prices continue to rise, inflationary pressures appear to
have eased, reducing the likelihood of continued interest rate hikes in the U.S.

Whatever the markets or the global economy may bring, the Fund will continue to
seek 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 EAFE Index.

CURRENT PERFORMANCE MAY BE LESS THAN THAT SHOWN. INVESTMENT RETURN AND PRINCIPAL
VALUE WILL FLUCTUATE SO THAT UPON REDEMPTION, SHARES MAY BE WORTH MORE OR LESS
THAN THEIR ORIGINAL COST.

(*)    Total returns shown herein include the change in share price and
       reinvestment of capital gain distributions and dividends, and, for the
       Service Class shares, include the service fee of .25% on an annualized
       basis of the average daily net asset value of the Service Class shares.

(+)    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 12/31/94. Performance figures
       for these two classes after this date will vary based on differences in
       their expense structures.

(++)   Lipper Inc. is an independent fund performance monitor. Results are based
       on total returns with capital gain and dividend distributions reinvested.

(sec.) The Morgan Stanley Capital International Europe, Australasia, and Far
       East Index--The EAFE Index--is an unmanaged index generally considered to
       be representative of the international stock market. Results assume the
       reinvestment of all dividend and capital gain distributions. An
       investment cannot be made directly into an index.

INTERNATIONAL BOND FUND
--------------------------------------------------------------------------------

International bond markets faced a number of difficulties during the 12 months
ended October 31, 2000. Monetary tightening by the U.S. Federal Reserve and
several of the world's other central banks tended to negatively impact bond
prices. The U.S. dollar's continuing strength versus other major international
currencies hurt bond returns for U.S. investors, even in markets that showed
positive results in local currency terms.

A Japanese fiscal stimulus package offered attractive promise early in 2000, but
provided little relief to bond investors. Europe continued to restructure its
companies, industries, and local economies as the European Union became well
established and the euro continued its downward slide through most of the year.

While global economic activity abated during the third calendar quarter of 2000,
oil prices surged to new highs, creating a dilemma for central bankers. The Bank
of England and the Federal Reserve Board chose to leave rates unchanged, while
the European Central Bank and Bank of Japan adjusted rates upward by 25 basis
points. While central banks now appear to be standing on the sidelines, the
impact for international bond investors has been negative throughout most of the
reporting period.

PERFORMANCE REVIEW

For the 12 months ended October 31, 2000, MainStay Institutional International
Bond Fund returned -13.34% for Institutional Class shares and -13.49% for
Service Class shares. Both share classes underperformed the -5.23% return of the
average Lipper(1) international income fund for the same period. During the
12-month period, both share classes underperformed the -9.70% return of the
Salomon Smith Barney Non-U.S. Dollar World Government Bond Index.(2)

Much of the Fund's underperformance was due to an underestimation of the
potential strength of the U.S. dollar versus other currencies. Anticipating a
turnaround in the euro throughout much of the year, the Fund was disappointed
not only by weak returns in local terms, but also in terms of currency
translations into U.S. dollars.

The Japanese and U.K. bond markets were strong performers in the last two months
of 1999, but the Fund was underweighted relative to the benchmark, which
detracted from performance. As we added Japanese holdings, we reduced duration,
anticipating excess supply from Japan's fiscal stimulus package. We also
established some tactical bond trades in related economies and took profits in
Danish bonds as the new year approached.

During the first calendar quarter of 2000, Australia, Canada, Sweden, and the
U.K. showed strong results in local currency terms. Despite sizeable holdings in
these countries, however, outside of Canada, currency weaknesses continued to
hurt the Fund's performance through the end of March 2000. Fearing additional
currency problems, the Fund neutralized its exposure to the yen. Nevertheless,
the Fund continued to maintain a bias toward the euro, which had a negative
impact throughout most of the remainder of the Fund's fiscal year.

--------------------------------------------------------------------------------
PAST PERFORMANCE IS NO GUARANTEE OF FUTURE RESULTS. DUE TO MARKET VOLATILITY,
CURRENT PERFORMANCE MAY BE LESS THAN THAT SHOWN. INVESTMENT RETURN AND PRINCIPAL
VALUE WILL FLUCTUATE SO THAT UPON REDEMPTION, SHARES MAY BE WORTH MORE OR LESS
THAN THEIR ORIGINAL COST. THE FUND'S NET ASSET VALUE WILL FLUCTUATE AND YOU
COULD LOSE MONEY BY INVESTING IN THE FUND.
The Fund may invest in derivatives, which may increase the volatility of the
Fund's net asset value and may result in a loss to the Fund. Investments in
foreign securities may be subject to greater risks than domestic investments.
These risks include currency fluctuations, changes in U.S. or foreign tax or
currency laws, and changes in monetary policies and economic and political
conditions in foreign countries. High-yield securities ("junk bonds") are
generally considered speculative because they present a greater risk of loss
than higher-quality debt securities; these securities may also be subject to
greater price volatility. Nondiversified funds may invest a greater percentage
of their assets than other funds in a particular issuer, which may make them
more susceptible to risks associated with a single economic, political, or
regulatory occurrence.

    total returns with capital gain and dividend distributions reinvested.
(2) The Salomon Smith Barney Non-U.S. Dollar World Government Bond Index is an
    unmanaged index generally considered to be representative of the world bond
    market. Total returns reflect reinvestment of all income and capital gains.
    An investment cannot be made directly into an index.

Australia, Canada, and the U.K. continued to show strength in local currency
terms during the second calendar quarter of 2000. Seeking a measure of security
during this period, the Fund maintained a conservative risk profile with a
neutral yield-curve position, limited credit exposure outside of Japan, and
underweighted Japanese holdings relative to the benchmark.

Despite these measures, the third calendar quarter of 2000 saw a continuing
deterioration in most international bond markets, particularly when returns were
translated into U.S. dollars. Canada, which was strong throughout the year both
in local currency and U.S. dollar terms, continued to show strength, and Greece
and Denmark also had positive returns in local terms during the third quarter.
The decision to underweight Japanese bonds proved beneficial during this portion
of the Fund's fiscal year, as Japanese government bonds posted negative total
returns, even in local currency terms.

Currency exposure continued to plague the Fund in October, as the euro declined
4% relative to the U.S. dollar during the month. In October, the Fund purchased
Irish gilts and 10-year French government bonds, seeking to capture additional
yield. The Fund also entered the Australian government bond market, since
spreads had widened about 50 basis points relative to U.S. Treasuries, and we
believed that spreads may narrow in the months ahead.

LOOKING AHEAD

We believe that a currency turnaround will be the key to profitability in
international bonds going forward. The dollar's strength has been remarkable,
but slowing global economic growth has combined with higher oil prices, lower
technology spending, and weaker equity performance to create a multithreaded
cord that continues to pull international bond returns downward. If the dollar
begins to weaken, we believe that the scenario we've witnessed this year could
begin to unravel, giving international bond investors a more favorable outlook.

Whatever the economy, currencies, or the markets may bring, the Fund will
continue to seek to provide total return by investing primarily in a portfolio
of non-U.S. (primarily government) debt securities.

PAST PERFORMANCE IS NO GUARANTEE OF FUTURE RESULTS. DUE TO MARKET VOLATILITY,
CURRENT PERFORMANCE MAY BE LESS THAN THAT SHOWN. INVESTMENT RETURN AND PRINCIPAL
VALUE WILL FLUCTUATE SO THAT UPON REDEMPTION, SHARES MAY BE WORTH MORE OR LESS
THAN THEIR ORIGINAL COST.

The inception date of MainStay Institutional International Bond Fund was 1/1/95.

(*)    The inception date of MainStay Institutional International Bond Fund's
       predecessor separate account ("Separate Account") is 1/31/90. Performance
       figures, and, in the case of the graphs reflecting the investment of
       $250,000, investment results include the historical performance of the
       Separate Account for the period prior to MainStay Institutional
       International Bond Fund's commencement of operations on 1/1/95. MacKay
       Shields LLC, the International Bond Fund's subadvisor, served as
       investment advisor to the Separate Account, and the investment objective,
       policies, restrictions, guidelines, and management style of the Separate
       Account were substantially similar to those of MainStay Institutional
       International Bond Fund. Performance figures and investment results for
       the period prior to 1/1/95 have been calculated using the Separate
       Account's expense structure, which generally was higher than the expense
       structure of MainStay Institutional International Bond Fund. The Separate
       Account was not registered under the Investment Company Act of 1940
       ("1940 Act") and therefore was not subject to certain investment
       restrictions imposed under the 1940 Act. If the Separate Account had been
       registered under the 1940 Act, the Separate Account's performance and
       investment results may have been adversely affected.

(+)    Total returns shown herein include the change in share price and
       reinvestment of capital gain distributions and dividends, and, for the
       Service Class shares, include the service fee of .25% on an annualized
       basis of the average daily net asset value of the Service Class shares.

(++)   Lipper Inc. is an independent fund performance monitor. Results are based
       on total returns with capital gain and dividend distributions reinvested.

(sec.) The Salomon Smith Barney Non-U.S. Dollar World Government Bond Index is
       an unmanaged index generally considered to be representative of the world
       bond market. Returns reflect reinvestment of all income and capital
       gains. An investment cannot be made directly into an index.

BOND FUND
--------------------------------------------------------------------------------

During the 12 months ended October 31, 2000, the U.S. bond market was affected
by a variety of forces. First was rapid economic growth, which the Federal
Reserve was committed to slowing. Next were a variety of inflationary threats,
including rising oil prices and continued low unemployment. Meanwhile, the
budget surplus prompted a Treasury buyback program that shifted supply and
demand dynamics in the Treasury market. Amid all of this, the Federal Reserve
raised the targeted federal funds rate four times--for a total of 1.25%. These
increases not only impacted the yield curve, but also made it more costly for
corporations to raise capital.

With the exception of convertible bonds, Treasury securities were the
best-performing income securities during the first ten months of 2000. Corporate
bonds, which had looked promising in the closing months of 1999, had mixed
results, while many investors felt the yields on mortgage-backed and
asset-backed securities were inadequate to justify the additional risks these
bonds involved. In October 2000, two government-sponsored enterprises, the
Federal National Mortgage Association (Fannie Mae) and the Federal Home Loan
Mortgage Corporation (Freddie Mac), voluntarily agreed to improve the
transparency of their disclosure provisions. This move was well accepted by the
market and improved the outlook for agency securities going forward.

PERFORMANCE REVIEW

For the 12 months ended October 31, 2000, MainStay Institutional Bond Fund
returned 6.21% for Institutional Class shares and 5.96% for Service Class
shares. Both share classes underperformed the 6.29% return of the average
Lipper(1) intermediate U.S. government fund for the same period. During the
12-month period, both share classes underperformed the 7.30% return of the
Lehman Brothers Aggregate Index.(2)

The Fund was positioned defensively in the last two months of 1999, in
anticipation of possible Y2K difficulties that never arose. Even so, the Fund
benefited by stressing high-quality, liquid bonds through the first quarter of
2000. In that quarter, mortgage-backed securities and corporate bonds tended to
underperform, as demand for Treasuries increased with the government's buyback
program.

During the first quarter of 2000, two Federal Reserve tightening moves helped
increase short-term rates enough to dramatically invert the yield curve.
Although that took a toll on the Fund's performance, during the second quarter
of 2000, signs that the economy was slowing brought demand into better balance
with supply. The Fund sold some of its long-term corporate bond positions to
take profits during this period, which had a positive impact on the Fund's
performance. The Fund's utility rate-reduction bond investments were among the
best-performing asset-backed securities in the second quarter of 2000 and also
contributed positively to the Fund's results. The Fund's duration strategy
during this period helped the Fund.

--------------------------------------------------------------------------------
PAST PERFORMANCE IS NO GUARANTEE OF FUTURE RESULTS. DUE TO MARKET VOLATILITY,
CURRENT PERFORMANCE MAY BE LESS THAN THAT SHOWN. INVESTMENT RETURN AND PRINCIPAL
VALUE WILL FLUCTUATE SO THAT UPON REDEMPTION, SHARES MAY BE WORTH MORE OR LESS
THAN THEIR ORIGINAL COST. THE FUND'S NET ASSET VALUE WILL FLUCTUATE AND YOU
COULD LOSE MONEY BY INVESTING IN THE FUND.
The Fund may invest in derivatives, which may increase the volatility of the
Fund's net asset value and may result in a loss to the Fund. Investments in
foreign securities may be subject to greater risks than domestic investments.
These risks include currency fluctuations, changes in U.S. or foreign tax or
currency laws, and changes in monetary policies and economic and political
conditions in foreign countries. Investments in the Fund are not guaranteed,
even though some of the Fund's investments are guaranteed by the U.S. government
or its agencies or instrumentalities.

(2) The Lehman Brothers Aggregate Index ("the Aggregate Index") includes the
    following other Lehman Brothers' indices: the Government Index, the
    Corporate Index, the Mortgage-Backed Securities Index, and the Asset-Backed
    Securities Index. To qualify for inclusion in the Aggregate Index,
    securities must be U.S. dollar-denominated and investment grade, and have a
    fixed-rate coupon, a remaining maturity or average life of at least one
    year, and a par amount outstanding of at least $150 million.

MARKET RALLY

The bond market rallied strongly in the third quarter of 2000, as it became
clear that the Federal Reserve's prior actions were having the desired effect.
Continually rising energy prices also helped to lower economic growth
expectations, although the potential impact on inflation remained a concern.
During the third quarter, the yield curve continued to shift, with the yield
spread between two-year and 30-year Treasuries declining by 38 basis points.
While this shift had a negative impact on Fund performance, stronger results
from the Fund's corporate, mortgage-backed, and asset-backed securities helped
strengthen third-quarter returns.

During October 2000, Treasuries remained strong performers, bolstered by a
projected budget surplus of $237 billion for fiscal 2000--nearly twice the level
a year before. The Fund's decision to remain overweighted in Treasury securities
had a positive impact on performance in October. We also chose to increase
exposure to agency securities, including Fannie Mae and Freddie Mac bonds, to
take advantage of wider spreads and recent initiatives that may increase demand,
while maintaining the Fund's underweighted position in corporate bonds.

LOOKING AHEAD

Recent interest-rate increases are beginning to be felt in both the "old" and
"new" sectors of the economy. While we don't believe this will lead to a
recession, we anticipate a moderation in growth and continued low inflation. We
believe this environment will be positive for Treasuries going into 2001. We
will continue to assess the impact of higher interest rates on corporate
earnings prospects and the mortgage market and will seek to adjust the portfolio
accordingly.

Whatever the markets or the economy may bring, the Fund will continue to seek to
maximize total return, consistent with liquidity, low risk to principal, and
investment in debt securities.

PAST PERFORMANCE IS NO GUARANTEE OF FUTURE RESULTS. DUE TO MARKET VOLATILITY,
CURRENT PERFORMANCE MAY BE LESS THAN THAT SHOWN. INVESTMENT RETURN AND PRINCIPAL
VALUE WILL FLUCTUATE SO THAT UPON REDEMPTION, SHARES MAY BE WORTH MORE OR LESS
THAN THEIR ORIGINAL COST.

(*)    Total returns shown herein include the change in share price and
       reinvestment of capital gain distributions and dividends, and, for the
       Service Class shares, include the service fee of .25% on an annualized
       basis of the average daily net asset value of the Service Class shares.

(+)    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 12/31/94. Performance figures
       for these two classes will vary after this date based on differences in
       their expense structures.

(++)   Lipper Inc. is an independent fund performance monitor. Results are based
       on total returns with capital gain and dividend distributions reinvested.

(sec.) The Lehman Brothers Aggregate Index (the "Aggregate Index") includes the
       following other Lehman Brothers' indices: the Government Index, the
       Corporate Index, the Mortgage-Backed Securities Index and the
       Asset-Backed Securities Index. To qualify for inclusion in the Aggregate
       Index, securities must be U.S. dollar-denominated and investment grade,
       and have a fixed-rate coupon, a remaining maturity or average life of at
       least one year, and a par amount outstanding of at least $150 million.
       Previously the Bond Fund has used the Lehman Brothers Gov't/Corporate
       Bond Index as a comparative broad-based securities market index.

INDEXED BOND FUND
--------------------------------------------------------------------------------

During the 12 months ended October 31, 2000, several forces affected the
investment-grade bond market. In the first half of the reporting period, the
rate of economic growth and the potential for inflation led to ongoing concerns
about Federal Reserve interest-rate hikes. Over the course of the 12-month
period, the Federal Reserve raised the targeted federal funds rate four times,
for a total of 1.25%.

Fortunately, in the third calendar quarter of 2000, concern about rising
interest rates seemed to abate somewhat, as evidence began to suggest that the
economy was slowing, rate increases were reducing stock market exuberance, and
earlier tightening moves were having the desired effect. Although the stock
market faced some setbacks during the year, they were generally positive for
bonds, as fund flows increased and investors moved into Treasuries to address
quality concerns.

During the reporting period, the government's Treasury buyback program decreased
the supply of older Treasury issues, which helped strengthen prices. A
Congressional inquiry into the status of the federal guarantee for government
sponsored enterprises caused agency securities to falter a bit, and in general,
the rising cost of borrowing had a negative impact on corporate bonds.

PERFORMANCE REVIEW

For the 12 months ended October 31, 2000, MainStay Institutional Indexed Bond
Fund returned 7.27% for Institutional Class shares and 6.87% for Service Class
shares. Both share classes outperformed the 6.77% return of the average
Lipper(1) general U.S. government fund for the same period. During the 12-month
period, both share classes underperformed the 7.28% return of the Salomon Smith
Barney Broad Investment Grade (BIG) Bond Index.(2) Investors should expect the
Fund to lag the Index somewhat, since the Fund faces real-world fees and
expenses that a hypothetical index does not.

As of October 31, 2000, the Fund's portfolio closely tracked its benchmark, with
an effective duration of 4.82 years (versus 4.84 years for the Index), and an
average coupon of 6.74% (versus 6.88% for the Index).

STRENGTHS AND WEAKNESSES

Rising interest rates during much of the Fund's fiscal year led to stock market
volatility and widening yield spreads between corporate bonds and comparable
Treasury securities. With investors seeking a high-quality alternative to stock
investments, particularly after technology stocks tumbled in April and May,
demand for Treasuries was strong. This strength was compounded by the
government's buyback program, which further diminished supply. As the yield
curve flattened, Treasuries outperformed other sectors, returning 8.22% over the
12-month reporting period. The Fund's use of a slight barbell
strategy--emphasizing the short and long ends of the yield curve, instead of
spreading exposure equally across the maturity spectrum--had a positive impact
on performance as the yield curve flattened and longer-dated issues outperformed
intermediate-term bonds.

--------------------------------------------------------------------------------
PAST PERFORMANCE IS NO GUARANTEE OF FUTURE RESULTS. DUE TO MARKET VOLATILITY,
CURRENT PERFORMANCE MAY BE LESS THAN THAT SHOWN. INVESTMENT RETURN AND PRINCIPAL
VALUE WILL FLUCTUATE SO THAT UPON REDEMPTION, SHARES MAY BE WORTH MORE OR LESS
THAN THEIR ORIGINAL COST.
The Fund may invest in derivatives, which may increase the volatility of the
Fund's net asset value and may result in a loss to the Fund. Investments in
foreign securities may be subject to greater risks than domestic investments.
These risks include currency fluctuations, changes in U.S. or foreign tax or
currency laws, and changes in monetary policies and economic and political
conditions in foreign countries.

Corporate bonds turned in the weakest performance for the Fund's fiscal year,
returning 5.40%. Within the corporate sector, quality impacted performance, with
AAA-rated corporate bonds returning 7.16% for the 12 months ended October 31,
2000, compared to BBB-rated corporates,(3) which returned just 4.00% over the
same period. During the fiscal year, the Fund benefited from judicious selection
among corporate issuers, which helped avoid any serious credit downgrades.

As interest rates rose, mortgage-backed securities benefited from decreasing
supply and slower prepayment rates, returning 7.67% for the Fund's fiscal year.
Despite concerns over federal guarantees, certain government sponsored
enterprises undertook voluntary initiatives to improve the transparency of their
disclosure. This was generally well-received in the market and helped boost
agency security performance in October. For the 12 months ended October 31,
2000, agencies returned 7.48%.

LOOKING AHEAD

With earnings disappointments rocking the corporate sector, we believe many
market participants may prefer higher-quality debt at least for the next several
months. As the government continues to buy back Treasuries, the decreasing
supply may impact both liquidity and benchmarking. Many investors now consider
the 10-year Treasury to be the bellwether Treasury issue, while some feel that
agency or corporate issues may eventually replace Treasuries as the bellwether
issue.

As we move into the new year, new forces may begin to shape economic and market
expectations. Whatever happens to interest rates or bond prices, the Fund will
continue to seek to provide investment results that correspond to the
total-return performance of fixed-income securities in the aggregate, as
represented by the Salomon Smith Barney Broad Investment Grade Bond Index.

(3) Bonds rated AAA by Standard & Poor's have the highest quality rating, and
    according to Standard & Poor's, the obligor's capacity to meet its financial
    commitment on the obligation is extremely strong. According to Standard &
    Poor's, debt rated BBB exhibits adequate protection parameters. However,
    adverse economic conditions or changing circumstances are more likely to
    lead to a weakened capacity of the obligor to meet its financial commitment
    on the obligation. These ratings are based solely on the creditworthiness of
    the bonds in the portfolio and are not meant to represent the stability or
    safety of the Fund.

Short-Term Bond Fund
--------------------------------------------------------------------------------

During the 12 months ended October 31, 2000, the Federal Reserve worked to slow
the rate of economic growth and keep inflation in check. To achieve these
objectives with oil prices rising, tight labor markets, and ongoing wage
pressures, the Federal Reserve raised the targeted federal funds rate four
times, for a total of 1.25%.

Short-term bond investors benefited from the higher yields that resulted from
the Federal Reserve's tightening moves. As the yield curve inverted, yields on
short-term securities rose substantially higher than those on longer-term bonds.
During the reporting period, a Treasury buyback program helped stabilize prices
and reduce supply among long-term government bonds.

After its May 16, 2000, rate hike, the Federal Reserve elected not to take
further tightening action. Widespread anticipation of the Fed's moves helped
keep bond markets stable and profitable for investors during the reporting
period.

PERFORMANCE REVIEW

For the 12 months ended October 31, 2000, MainStay Institutional Short-Term Bond
Fund returned 6.05% for Institutional Class shares and 5.78% for Service Class
shares. Institutional Class shares outperformed and Service Class shares
underperformed the 6.01% return of the average Lipper(1) short-term U.S.
government fund for the same period. During the 12-month period, both share
classes underperformed the 6.06% return of the Salomon Smith Barney 1-3 Year
Treasury Index.(2)

The Fund's Institutional Class shares were rated five stars overall and its
Service Class shares were rated four stars overall out of 1,208 taxable bond
funds by Morningstar(3) as of October 31, 2000. Both share classes were rated
five stars out of 1,208 taxable bond funds for the three-year period then ended,
and Institutional Class shares were rated five stars and Service Class shares
four stars out of 750 taxable bond funds for the five-year period then ended.

POSITIONING THE PORTFOLIO

With Y2K computer concerns on many investors' minds, the Fund concentrated on
maintaining a relatively defensive posture in November and December of 1999. At
the end of 1999, the Fund was over 95% invested in government, AAA-rated, or
cash equivalent securities. This defensive positioning provided investors with a
measure of security in an uncertain period.

During the first calendar quarter of 2000, the Fund maintained a high-quality
portfolio, with approximately 50% of assets invested in Treasury securities as
of March 31, 2000. This benefited the portfolio, as Treasuries were the best
performing asset class during this calendar quarter.

During the second calendar quarter, the Fund increased its commitment to
Treasuries, which continued to benefit shareholders. In search of
higher-yielding securities with high credit quality, nearly 40% of the portfolio
was invested in agency and AAA-rated asset-backed securities, which helped
performance.

By the end of September 2000, the Fund had reduced its commitment to Treasuries
to about 37% of the portfolio. Approximately 40% was invested in U.S. agency
securities, 10% in corporate securities, and 9% in asset-backed securities. The
Fund's decision to

    no guarantee of future results.

overweight higher-yielding agency securities and other spread products
contributed positively to the Fund's performance during the third calendar
quarter.

After some concerns arose over federal guarantees on securities of various
government sponsored enterprises, in October, the Federal National Mortgage
Association and the Federal Home Loan Mortgage Corporation voluntarily agreed to
make their disclosure provisions more transparent. These moves were well
accepted by investors and had a positive impact on the overall market for agency
securities. The Fund's strong commitment to agency securities during this period
contributed positively to the Fund's performance.

Throughout the reporting period, the quality of most of the securities in the
Fund's investment portfolio was very high. As opportunities arose, we continued
to seek spread advantages over Treasuries within the Fund's quality guidelines.

LOOKING AHEAD

Although we consider it unlikely that the Federal Reserve will tighten interest
rates again in 2000, we recognize that rising oil prices, low unemployment, and
wage pressures may continue to exert inflationary pressures, even as the growth
of the economy begins to slow.

Whatever the markets or the economy may bring, the Fund will continue to seek to
maximize total return, consistent with liquidity, preservation of capital, and
investment in short-term debt securities.

PAST PERFORMANCE IS NO GUARANTEE OF FUTURE RESULTS. DUE TO MARKET VOLATILITY,
CURRENT PERFORMANCE MAY BE LESS THAN THAT SHOWN. INVESTMENT RETURN AND PRINCIPAL
VALUE WILL FLUCTUATE SO THAT UPON REDEMPTION, SHARES MAY BE WORTH MORE OR LESS
THAN THEIR ORIGINAL COST.

(*)    Total returns shown herein include the change in share price and
       reinvestment of capital gain distributions and dividends, and, for the
       Service Class shares, include the service fee of .25% on an annualized
       basis of the average daily net asset value of the Service Class shares.

(+)    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 12/31/94. Performance figures
       for these two classes will vary after this date based on differences in
       their expense structures.

(++)   Lipper Inc. is an independent fund performance monitor. Results are based
       on total returns with capital gain and dividend distributions reinvested.

(sec.) The Salomon Smith Barney 1-3 Year Treasury Index is an unmanaged index
       that is generally considered to be representative of the U.S. short-term
       bond market. Returns reflect reinvestment of all income and capital
       gains. An investment cannot be made directly into an index.

Money Market Fund
--------------------------------------------------------------------------------

During the 12 months ended October 31, 2000, the Federal Reserve raised the
targeted federal funds rate on four separate occasions--for a total increase of
1.25%. Since each of these rate hikes raised money market yields, the moves were
generally well received by money market investors.

The period from November 1999 through April 2000 was marked by concerns about
strong economic growth, tight labor markets, rising oil prices, and the possible
impact these forces might have on inflation. When the Federal Reserve increased
the targeted federal funds rate by 50 basis points on May 16, 2000, however,
many investors believed the worst was over. In the second half of the Fund's
fiscal year, economic growth slowed, inflationary pressures seemed to ease, and
short-term rates improved as concerns over further Fed tightening subsided.

PERFORMANCE REVIEW

For the 12 months ended October 31, 2000, MainStay Institutional Money Market
Fund returned 5.98% for Institutional Class shares, 5.72% for Service Class
shares, and 5.46% for Sweep Shares Class shares. As of October 31, 2000 the
Fund's 7-day current yield was 6.21%, 5.97%, and 5.72%, for the respective share
classes. All share classes underperformed the 5.99% return of the average
Lipper(1) institutional money market fund.

STRATEGIES AND SECTOR WEIGHTINGS

During the fiscal year ended October 31, 2000, the Fund's weighted average
maturity ranged from 30 days to 72 days. The Fund was able to profit from
shorter maturities when the Federal Reserve was raising rates, by quickly taking
advantage of rate changes. The Fund also managed to lock in higher rates with
longer maturities before the Fed halted its rate hikes and rates started to
drift downward. While not always perfectly timed, the Fund's duration changes
generally contributed positively to performance throughout the Fund's fiscal
year.

During the reporting period, the Fund was occasionally willing to give up
liquidity for higher income potential. This led to purchases of asset-backed
securities, asset-backed commercial paper, and floating-rate securities. We
continue to find that keeping a portion of the portfolio in these high-quality
alternatives tends to benefit the Fund's return in the long run.

Significant purchases during the year included floaters issued by Caterpillar
Financial Services, Heller Financial, Unilever Capital, and AT&T, as well as an
asset-backed security issued by Wesley Commercial and Residential Securities
Funding Trust I. All of these investments outperformed discounted commercial
paper over their respective holding periods.

LOOKING AHEAD

We intend to continue seeking opportunities to enhance the Fund's total return
by purchasing higher-yielding securities with 2001 maturities. In addition, we
will continue to look for alternatives to commercial paper that offer potential
to enhance income without sacrificing quality.

Whatever the markets or the economy may bring, the Fund will continue to seek a
high level of current income while preserving capital and maintaining liquidity.

PAST PERFORMANCE IS NO GUARANTEE OF FUTURE RESULTS. DUE TO MARKET VOLATILITY,
CURRENT PERFORMANCE MAY BE LESS THAN THAT SHOWN.

Investments in MainStay Institutional Money Market Fund are not insured or
guaranteed by the Federal Deposit Insurance Corporation or any other government
agency. Although the Fund seeks to preserve the value of your investment at
$1.00 per share, it is possible to lose money by investing in the Fund.

(*)    Total returns shown herein include the change in share price and
       reinvestment of capital gain distributions and dividends, and, for the
       Service Class shares, include the service fee of .25% on an annualized
       basis of the average daily net asset value of the Service Class shares.

(+)    Performance figures for the Sweep Shares Class, first offered to the
       public on 12/8/98, include the historical performance of the Service
       Class from the Service Class's inception (1/1/95) up to 12/7/98.
       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 12/31/94. Performance figures
       for these classes will vary after these dates based on differences in
       their expense structures.

(++)   MainStay Institutional Money Market Fund had an effective 7-day yield of
       6.41% for the Institutional Class; 6.14% for the Service Class; and 5.88%
       for the Sweep Shares Class; all as of 10/31/00. These yields reflect
       certain expense limitations. Had these expense limitations not been in
       effect, the effective 7-day yield and the current 7-day yield would have
       been 6.31% and 6.12%, respectively, for the Institutional Class; 6.05%
       and 5.87%, respectively, for the Service Class; and 5.78% and 5.62%,
       respectively, for the Sweep Shares Class. These expense limitations are
       voluntary and may be terminated or revised at any time.

(sec.) Lipper Inc. is an independent fund performance monitor. Results are based
       on total returns with capital gain and dividend distributions reinvested.

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 October 31, 2000, the Company has eleven separate investment
portfolios: Growth Equity Fund, Indexed Equity Fund, Value Equity Fund, Asset
Manager Fund, International Equity Fund, EAFE Index Fund, International Bond
Fund, Bond Fund, Indexed Bond Fund, Short-Term Bond Fund and Money Market Fund
(individually or collectively referred to as a "Fund" or the "Funds"). The
International Equity Fund and the International Bond 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. In addition, the Money
Market Fund offers a third class of shares, the Money Market Fund Sweep Shares
Class. The Company has adopted a Shareholder Services Plan with respect to each
class of each Fund. The shares classes are substantially the same, except that
the Institutional Service Class shares and the Money Market Fund Sweep Shares
Class each bears the fees payable under the Shareholder Services Plan for that
class at an annual rate of 0.25% of the average daily net assets of the
outstanding shares of the class. The Money Market Fund Sweep Shares Class also
bears the payment of fees at an annual rate of 0.25% of the average daily net
assets of the outstanding Sweep Shares for services in support of distribution
activities under a distribution plan pursuant to Rule 12b-1 under the Investment
Company Act ("Distribution Plan"). The distribution of Institutional Service
Class shares commenced on January 1, 1995. The distribution of the Money Market
Fund Sweep Shares Class commenced on December 8, 1998.

    The investment objectives for each of the Funds of the Company are as
follows:

    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 S&P 500 Composite Stock Price
Index.

    The VALUE EQUITY FUND seeks maximum long-term total return from a
combination of capital growth and income.

    The ASSET MANAGER FUND seeks to maximize total return, consistent with
certain percentage constraints on amounts allocated to each asset class, from a
combination of common stocks (selected to parallel the performance of the S&P
500 Index, the S&P MidCap 400 Index, the S&P SmallCap 600 Index and the Morgan
Stanley REIT Index), fixed income securities (selected to parallel the
performance of the Salomon Smith Barney Broad Investment Grade Bond Index), and
money market investments.

    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 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, Australasia and Far East 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 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 Smith Barney Broad Investment Grade Bond Index.

    The SHORT-TERM BOND FUND seeks to maximize total return, consistent with
liquidity, preservation of capital and investment in short-term debt securities.

    The MONEY MARKET FUND seeks to provide a high level of current income while
preserving capital and maintaining liquidity.

    There are certain risks involved in investing in foreign securities that are
in addition to the usual risks inherent in domestic instruments. These risks
include those resulting from future adverse political and economic developments
and possible imposition of currency exchange blockages or other foreign
governmental laws or restrictions.

--------------------------------------------------------------------------------
NOTE 2--Significant Accounting Policies:
--------------------------------------------------------------------------------

    The following is a summary of significant accounting policies followed by
the Company:

                                      (A)

VALUATION OF FUND SHARES.  The net asset value per share of each 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, except for the Money Market Fund, which is calculated at noon every
day the Exchange is open. The net asset value per share of each Class of shares
is determined by taking the current market value of total assets attributable to
that Class, except for the Money Market Fund, which is based on the amortized
cost method of valuation, 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
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 subadvisor if such prices are
deemed to be representative of market values at the regular close of business of
the Exchange; (e) by appraising debt securities at prices supplied by a pricing
agent selected by a Fund's subadvisor, whose prices reflect broker/dealer
supplied valuations and electronic data processing techniques if those prices
are deemed by a Fund's subadvisor to be representative of market values at the
regular close of business of the Exchange; (f) by appraising options and futures
contracts at the last sale price on the market where any such options 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
subadvisor to be representative of market values, but excluding money market
instruments with a remaining maturity of 60 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 Company's
Board of Directors. Short-term securities which mature in more than 60 days are
valued at current market quotations. Short-term securities which mature in 60
days or less are valued at amortized cost if their term to maturity at purchase
was 60 days or less, or by amortizing the difference between market value on

                                       139
<PAGE>   143
NOTES TO FINANCIAL STATEMENTS (Continued)

the 61st day prior to maturity and value on maturity date if their original term
to maturity at purchase exceeded 60 days.

    Events affecting the values of portfolio securities that occur between the
time their prices are determined and the close of the Exchange will not be
reflected in the Funds' calculation of net asset values unless a Fund's
subadvisor deems that the particular event would materially affect such Fund's
net asset value, in which case an adjustment may 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.

                                      (D)

DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS.  Dividends and distributions 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, as a dividend, substantially all of their net investment income and net
realized capital gains no less frequently than once a year. Income dividends and
capital gain distributions are determined in accordance with federal tax
regulations, which may differ from generally accepted accounting principles.
These "book/tax differences" are either considered temporary or permanent in
nature. To the extent these differences are permanent in nature, such amounts
are reclassified within the capital accounts based on their federal tax basis
treatment; temporary differences do not require reclassification. Dividends and
distributions which exceed net investment income and net realized capital gains
for financial reporting purposes but not for federal tax purposes are reported
as dividends in excess of net investment income or distributions in excess of
net realized capital gains.

    The following table discloses the current year reclassifications between
accumulated undistributed net investment income (loss) and accumulated
undistributed net realized gain (loss) on investments and paid-in capital
arising from permanent differences; net assets at October 31, 2000 are not
affected.

The reclassifications for the Funds are primarily due to foreign currency gain
(loss), distributions in excess of net investment income, gain on sales of
passive foreign investment companies, paydown gain (loss), gain from redemption
in kind, and net operating losses.

fiscal year end from December 31 to October 31.

                                      (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 a Fund are accreted 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. Discounts on short-term
securities are accreted on the straight line method. Premiums on securities
purchased are not amortized for any Fund except the Money Market Fund, which
amortizes the premium on the constant yield method over the life of the
respective securities.

                                      (G)

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 direct allocations of expenses can be made.

    The investment income and expenses (other than expenses incurred under the
Shareholder Services Plans and the Distribution 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.

                                      (H)

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.

                                      (I)

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 year. The realized and unrealized gains and losses on
securities arising from changes in exchange rates and those resulting from
changes in market prices are not separately presented, except that International
Bond Fund isolates the effect of changes in foreign exchange rates from the
fluctuations arising from changes in the market prices of long-term debt
securities sold during the year.

    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 Funds' 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 year-end exchange rates are reflected in
unrealized foreign exchange gains or losses. Realized gains and losses from
certain foreign currency transactions are treated as ordinary income for federal
income tax purposes.

FOREIGN CURRENCY FORWARD CONTRACTS.  A foreign currency forward 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. Foreign currency forward contracts are used
for hedging purposes or to seek to enhance investment returns: (see Note 5).

The use of foreign currency forward contracts involves, to varying degrees,
elements of market risk in excess of the amount recognized in the statement of
assets and liabilities. The contract amount reflects the extent of the Fund's
involvement in these financial instruments. Risks arise from the possible
movements in the

(depreciation) on forward contracts reflects the Fund's exposure at year-end to
credit loss in the event of a counterparty's failure to perform its obligations.

PURCHASED AND WRITTEN OPTIONS.  Certain Funds may write covered call and put
options on their portfolio securities or foreign currencies. Premiums are
received and are recorded as liabilities. The liabilities are subsequently
adjusted to reflect the current value of the options written. Premiums received
from writing options which expire are treated as realized gains. Premiums
received from writing options which are exercised or are cancelled in closing
purchase transactions are added to the proceeds or netted against the amount
paid on the transaction to determine the realized gain or loss. By writing a
covered call option, a Fund foregoes in exchange for the premium the opportunity
for capital appreciation above the exercise price should the market price of the
underlying security or foreign currency increase. By writing a covered put
option, a Fund, in exchange for the premium, accepts the risk of a decline in
the market value of the underlying security or foreign currency below the
exercise price.

    Certain Funds may purchase call and put options on its portfolio securities
or foreign currencies. A Fund may purchase call options to protect against an
increase in the price of the security or foreign currency it anticipates
purchasing. A Fund may purchase put options on its securities or foreign
currencies to protect against a decline in the value of the security or foreign
currency or to close out covered written put positions. A Fund may also purchase
options to seek to enhance returns. Risks may arise from an imperfect
correlation between the change in market value of the securities or foreign
currencies held by the Fund and the prices of options relating to the securities
or foreign currencies purchased or sold by the Fund and from the possible lack
of a liquid secondary market for an option. The maximum exposure to loss for any
purchased option is limited to the premium initially paid for the option.

CONCENTRATION.  At October 31, 2000, substantially all of the International
Equity Fund's, EAFE Index Fund's and International Bond Fund's net assets
consisted of securities of issuers which are denominated in foreign currencies.
Changes in currency exchange rates will affect the value of and investment
income from such securities.

As of October 31, 2000, the EAFE Index Fund and the International Bond Fund
invested approximately 24.3% and 31.0%, respectively, of its net assets in
issuers in Japan. The issuers' abilities to meet their obligations may be
affected by economic or political developments in Japan.

Substantially all of the International Equity Fund's, EAFE Index Fund's and
International Bond Fund's net assets consist of securities which are generally
subject to greater price volatility, limited capitalization and liquidity, and
higher rates of inflation than securities of companies based in the United
States. In addition, issuers of certain securities may be subject to substantial
governmental involvement in the economy and social, economic and political
uncertainty.

                                      (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 and
price, or to make or receive a cash payment based on the value of a securities
index foreign currency or interest rate. 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. A 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 or to seek to enhance returns: (see Note
5).

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 MDRs
are removed from the portfolio and a realized gain or loss is recognized. The
securities the Funds have agreed to acquire are included at market value in the
portfolio of investments and liabilities for such purchase commitments are
included as payables for investments purchased. The 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.  Each Fund may lend its securities to broker-dealers and
financial institutions. The loans are secured by collateral (cash or securities)
at least equal at all times to the market value of the securities loaned. The
Fund may bear the risk of delay in recovery of, or loss of rights in, the
securities loaned should the borrower of the securities experience financial
difficulty. 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.

    At October 31, 2000, the Bond Fund and Short-Term Bond Fund had portfolio
securities with a fair market value of $23,589,133 and $5,851,569, respectively,
on loan to broker-dealers and government securities dealers.

    Cash collateral received by the Bond Fund and Short-Term Bond Fund are
invested in investment grade commercial paper, or other securities in accordance
with the Funds' Securities Lending Procedures. Such investments are included as
an asset and a corresponding liability in the Statement of Assets and
Liabilities. While these Funds invest cash collateral in investment grade
securities or other "high quality" investment vehicles, the Funds bear the risk
that liability for the collateral may exceed the value of the investment.

    Non-cash collateral received and held by the Bond Fund and Short-Term Bond
Fund, in the form of U.S. Government obligations, had a value of $344,511 and
$53,120, respectively, at October 31, 2000.

    Net income earned on securities lending amounted to $110,598 and $19,656,
net of broker fees and rebates, for the Bond Fund and Short-Term Bond Fund,
respectively, for the year ended October 31, 2000 and is included as interest
income on the Statement of Operations.

    The Value Equity Fund's, Asset Manager Fund's, International Equity Fund's,
EAFE Index Fund's and International Bond Fund's use of foreign currency 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 foreign currency forward contracts reflects each Fund's exposure at year-end
to credit loss in the event of a counterparty's failure to perform its
obligations.

    The Asset Manager Fund and EAFE Index Fund use foreign currency forward
contracts to minimize the risk of loss to the Fund from adverse changes in the
relationship between the U.S. dollar and foreign currencies.

    The Value Equity Fund, International Equity Fund and International Bond Fund
enter into foreign currency forward contracts in order to protect against
uncertainty in the level of future foreign currency exchange rates, or to seek
to enhance the Funds' investment returns in the case of the International Equity
Fund and the International Bond Fund.

    The Indexed Equity Fund's, Asset Manager Fund's, EAFE Index 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 Indexed Equity Fund and EAFE Index Fund invest in stock index futures
contracts to maintain cash reserves while remaining fully invested, to
facilitate trading, or to reduce transaction costs. The Asset Manager 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.

--------------------------------------------------------------------------------
NOTE 6 -- Line of Credit:
--------------------------------------------------------------------------------

    The Funds, with the exception of the Money Market Fund, maintain a line of
credit of $375,000,000 with a syndicate of banks in order to secure a source of
funds for temporary purposes to meet unanticipated or excessive shareholder
redemption requests. The Funds pay a commitment fee, at an annual rate of .075%
of the average commitment amount, regardless of usage, to the Bank of New York,
which acts as agent to the syndicate. Such commitment fees are allocated amongst
the Funds based upon net assets and other factors. Interest on any revolving
credit loan is charged based upon the Federal Funds Advances rate. There were no
borrowings on the line of credit during the year ended October 31, 2000.

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 Asset Manager Fund, EAFE Index
Fund, Growth Equity Fund, Indexed Equity Fund, International Equity 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 October 31, 2000, the results of each
of their operations for the year then ended, and the changes in each of their
net assets and the financial highlights for each of the periods indicated, in
conformity with accounting principles generally accepted in the United States of
America. 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 auditing standards generally accepted in the United States of
America, 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 October 31, 2000 by
correspondence with the custodian and brokers, provide a reasonable basis for
our opinion.
