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

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

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

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

 ++ The Money Market Fund-Institutional Class had an effective 7-day yield of
    5.07% with an average 7-day yield of 4.95%, both as of 6/26/96. The Money
    Market Fund-Service Class had an effective 7-day yield of 4.81% with an
    average 7-day yield of 4.70%, both as of 6/26/96. The Administrator has
    agreed to assume a portion of the expenses for these Funds. Had certain
    expenses not been assumed by the Administrator, the effective 7-day yield
    and the average 7-day yield would have been 4.89% and 4.78%, respectively,
    for the Institutional Class and 4.63% and 4.53%, respectively, for the
    Service Class.

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

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

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

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

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

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

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

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

        REPORT TO SHAREHOLDERS FOR THE SIX MONTHS ENDED JUNE 30, 1996


Strategic security selection amid powerful economic forces and shifting market
perceptions--this was the strategy that guided the management of MainStay's
actively managed Institutional Funds for the six months ended June 30, 1996. Our
international portfolios added careful country selection and selective currency
hedging in an effort to enhance returns, and our income Funds pursued investment
opportunities with a focus on quality, duration, and shifting relative values.
During this period, our index-based funds continued to pursue their objectives
of closely tracking their respective indices.

Outstanding Performance

                   Based on these strategies, what were our results? Of the
                   eight MainStay Institutional Funds that qualify for
                   Morningstar* ratings, six received four or five stars
                   overall, placing them in the top 33% or top 10% of their
                   respective categories. As of June 30, 1996, the Value Equity
  [PHOTO OF        Fund earned five stars, Morningstar's highest overall rating,
  ALICE T. KANE,   and the Indexed Equity Fund received four stars. Both ratings
  CHAIRPERSON      were based on a Morningstar universe of 1,583 equity funds
  APPEARS HERE]    for the 3-year period and 997 equity funds for the 5-year
                   period ended 6/30/96. Four-star overall ratings were also
                   awarded to the Bond, Indexed Bond, and Short-Term Bond Funds,
                   each based on a universe of 889 fixed-income funds for the
                   3-year period and 464 fixed-income funds for the 5-year
                   period ended 6/30/96. The Multi-Asset Fund also earned a 
                   four-star overall rating, based on a universe of 2,848 hybrid
                   funds for the 3-year period and 1,696 hybrid funds for the 
                   5-year period ended 6/30/96.

A Stronger Economy--Good for Stocks, Challenging for Bonds

After a spectacular 1995, the stock market continued to climb for most of the
first half of 1996--but not without setbacks along the way. The economy was
stronger than expected, which led to inflation concerns, rising interest rates,
and price volatility. With the S&P 500 Stock Index+ advancing 10.09% in the
reporting period, the stock market delivered a six-month return close to its
historical average for an entire year.(S) Small capitalization stocks did even
better, but faced a sharp correction in mid-June. Investors were very active,
pouring more money into stock funds in the first six months than they had in any
full year in history.++ Whether the returns and investment activity we've seen
in the first half of the year can be sustained through what may be a volatile
second half remains an open question.

Bonds had a difficult time during this period. The improving economy generally
hurt fixed-income investors, but boosted prices among lower-rated bonds. In
March, unexpected payroll gains, which indicated higher employment, caused bond
prices to plummet. In a single day, 30-year Treasury bond prices fell 3.3% and
most domestic bond categories, except high current yield, closed the first
quarter with negative returns. As employment rose in the second quarter, so did
long-term rates, with the 30-year Treasury bond yielding 6.90% at the end of
June (up from 5.95% at year-end 1995).

Rising interest rates affected more than just bonds. They also led to price
corrections in financial and consumer nondurable stocks. Economically sensitive
sectors such as chemicals and consumer cyclicals showed sparks of progress
during the first quarter, which failed to ignite in the second. Retail stocks,
on the other hand, did well, based on strong consumer spending while health care
and technology stocks provided mixed results.

Positive Results in International Markets

Foreign equity markets lagged the U.S. during the first quarter of 1996, but
provided more competitive returns in the second. Latin America posted strong
gains and Japan showed signs of economic recovery, which boosted its equity

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

        REPORT TO SHAREHOLDERS FOR THE SIX MONTHS ENDED JUNE 30, 1996


returns to 43.5% for the 12 months ended June 30, 1996. During the reporting
period, small company funds did well in European markets, as they did in the
U.S. In all but a handful of markets, foreign currencies declined against the
U.S. dollar, led by weaknesses in the Japanese yen and core European currencies.
Foreign bond markets generally outperformed U.S. bond markets during the
reporting period, increasing the potential value of international
diversification.

Investment Outlook

Specific strategies and performance results for each Fund, in accordance with
each Fund's objectives and investment disciplines, are discussed in greater
detail in the Fund managers' comments on the following pages.

While the results of the last six months can't tell us what will happen next,
they may help us form realistic expectations based on historical trends. Viewed
in this light, a more moderate second half in the equity markets, and continued
fluctuations in interest rates and bond values would not come as a surprise.
Regardless of what the future holds, investors may benefit by maintaining a
long-range perspective and adding to their accounts over time. With the
recognition that ups and downs are a natural part of long-term investing, our
shareholders can make adjustments when warranted and stay focused on the 
future--even during volatile periods.

Five Years of Shareholder Service

MainStay Institutional Funds Inc. celebrated its 5th anniversary as a Fund group
in January, passing a major milestone for nine of our Funds.  It has been our
pleasure to serve you during the last six months, and we look forward to
continuing to do so for many years to come.

Sincerely,


/s/ Alice T. Kane

 *  Morningstar, Inc. is an independent fund performance monitor. Its ratings
    reflect historic risk-adjusted performance, which does not include sales
    charges, and may change monthly. Its ratings of 1 (low) and 5 (high) stars
    are based on a fund's 3-, 5- & 10-year average annual returns with fee
    adjustments, and a risk factor that reflects fund performance relative to 3-
    month Treasury bill monthly returns. A one-year rating is calculated using
    the same methodology, but is not a component of the overall rating. As of
    6/30/96, the individual 1, 3 and 5 year ratings for these periods for the
    following MainStay Institutional Funds were as follows: Bond Fund, 3, 3 and
    4 stars; Indexed Bond Fund, 3, 3 and 4 stars; Short-Term Bond Fund, 4, 4 and
    4 stars; Multi-Asset Fund, 4, 4 and 4 stars; Indexed Equity Fund, 5, 4 and 4
    stars; Value Equity Fund, 3, 4 and 5 stars, respectively. For the one-year
    period, the Indexed Equity and Value Equity Funds were rated among 2,882
    funds in the equity category, the Bond, Indexed Bond and Short-Term Bond
    Funds were rated among 1487 funds in the fixed-income category, and the
    Multi-Asset Fund was rated among 5,076 funds in the hybrid category. Only
    10% of the funds in an investment category may receive 5 stars, 22.5% may
    receive 4 stars 35% may receive 3 stars, and 22.5% may receive 2 stars.
    Ratings reflect Institutional Class performance only. Service Class shares,
    the International Equity Fund and the International Bond Fund, all
    introduced January 1, 1995, will not be rated by Morningstar until they have
    a three year operating history.

PORTFOLIO MANAGER'S COMMENTS


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

Fund Highlights for the six months ended June 30, 1996

 . One-year total returns of 12.53% and 12.07% for Institutional Class and
   Service Class shares, respectively, as of 6/30/96

 . For the six months ended 6/30/96, strong gains in local terms for the Morgan
   Stanley Capital International (MSCI) EAFE Index* were eroded by currency
   shifts relative to the U.S. dollar

 . Strong performance from Ireland, Italy, and Spain during the reporting
   period

For the six months ended June 30, 1996, the MainStay Institutional EAFE Index
Fund returned 5.01% and 4.96% for Institutional Class and Service Class shares,
respectively. During the reporting period, the Fund underperformed the average
Lipper(S) international equity fund, which gained 8.02%.

Many markets around the globe posted strong gains for the first half of 1996.
Over half the countries in the Morgan Stanley Capital International EAFE Index
even topped the 10.09% return on the S&P 500 Index.+ The persistent strength of
the U.S. dollar, however, substantially reduced this return to U.S. investors.
While the EAFE Index rose almost 9% in local terms during the first half, the
Index gained only 4.52% after adjusting for currency fluctuations versus the
U.S. dollar.

The yen-dollar exchange rate had the most profound effect on Fund performance
during the first half of 1996. The Japanese market accounts for almost 40% of
the EAFE Index. In local terms, this portion of the Index gained 7.5%. The
strong dollar--and corresponding weakness of the Japanese yen--reduced the
return to only 1.13% in dollar terms.

Ireland was the best performing market in the EAFE Index, providing an 18.5%
return (in local terms) over the reporting period. However, since this market
makes up only 0.3% of the Index, Irish gains had little impact on overall Fund
performance. Other strong performers were Spain and Italy, which climbed 13.9%
and 12.6%, respectively (also in local terms). In April, the victory of Italy's
center-left coalition propelled the Italian stock market higher as the prospect
of political stability and budget cuts encouraged investors. In Spain, the
market surged as the government took steps toward economic reform. The worst
performing market in the EAFE Index was Singapore, which returned -3.22%. Of the
20 countries represented in the EAFE Index, Singapore was the only one to post a
loss in the first half of the year.

In managing the Fund, we monitor the composition and seek to provide the
investment results of the EAFE Index as closely as possible, regardless of the
movements of the individual markets that make it up. Since the Fund does not
hedge currency exposure, the high weighting in, and relatively poor return on,
Japanese equities caused the Fund to substantially underperform the Lipper
international equity fund average.

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

 *  The MSCI EAFE Index is an unmanaged index generally considered
    representative of the international stock market.
(S) Lipper Analytical Services Inc. is an independent monitor of mutual fund
    performance. Results do not reflect any deduction of sales charges and are

 +  The S&P 500 Stock Index is a registered trademark of Standard & Poor's
    Corporation.  S&P 500 Stock Index is an unmanaged index that is considered
    representative of the U.S. stock market.


Local terms Performance reports in local terms reflect results within a specific
country, with returns denominated in its local currency.  It does not consider
the impact of currency fluctuations or exchange rates when translated into other
currencies.

Exchange rate The amount of one currency that may be exchanged for a single unit
of another at any given time. Exchange rates may vary, causing gains or losses
in the value of international investments when local returns are translated into
U.S. dollars.

Economic reform Steps taken by a government to enhance or control the growth of
the national economy. Such reforms might include steps to increase employment,
control wages, enhance productivity, manipulate the cost of loans, or otherwise
influence the availability of capital.

Currency management/hedging The process of managing or "hedging" the risks
associated with owning securities denominated in different currencies, the
relative values of which may change at any time. There can be no assurance that
currency hedging will be beneficial to investors.

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

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

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

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

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

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

Fund Highlights for the six months ended June 30, 1996

 .Exceeded the S&P 500 Stock Index+ and the average Lipper(S) growth fund for the
 six months ended 6/30/96

 .Strong performance from HFS, our largest holding as of 6/30/96, and Nike, our
 largest purchase in the first six months of 1996

For the six months ended June 30, 1996, the MainStay Institutional Growth Equity
Fund returned 11.04% and 10.85% for Institutional Class and Service Class
shares, respectively. During the reporting period, the Fund outpaced both the
average Lipper growth fund and the S&P 500 Stock Index, with the average Lipper
growth fund returning 10.08% and the S&P 500 returning 10.09%.

After a lackluster 1995, consumer cyclicals bounced back in March. Our bottom-up
stock selection benefited the portfolio, with securities such as Bed Bath &
Beyond, Lowe's, and Home Depot recording double-digit returns in March. We were
attracted to Nike for its accelerating sales, new product introductions, and
strong potential in an Olympic year, and made it our largest purchase in the
first half of 1996. With an outstanding return in the first half of 1996, Nike
shared the footlights with Nine West among the portfolio's top performers.

The Fund's top holding, HFS, was also its best performer. The company announced
the acquisition of Avis, adding a recognized car rental brand to its hotel and
real estate brand name businesses. Other strong consumer stocks in the Fund's
portfolio in the second quarter were Mirage Resorts and CUC International, a
membership-based consumer services company.

The Fund's financial stocks had mixed performance in the first six months of
1996. After a surprisingly strong employment report in early March, any hopes of
the Fed lowering interest rates were dashed, the bond market dropped sharply,
and interest-sensitive bank and insurance stocks suffered. As rates began to
climb, we took some profits, which benefited the portfolio. Nevertheless, we
remained overweighted in financials relative to the S&P 500 Stock Index because
the fundamentals were, and continue to be, compelling for selected stocks in the
group. Therefore, we concluded the first quarter with an emphasis on consumer
finance companies.

In the second quarter, a volatile bond market and credit quality concerns led
financial stocks to underperform. The Bank of New York announced larger-than-
expected reserves for bad consumer loans, which led us to sell the stock before
the end of the quarter. Green Tree Financial and First USA, which we believe
continue to have strong potential, were notable underperformers for the
portfolio in this environment. Our decision to hold SunAmerica, First Data, and
Household International, however, benefited the Fund, as each recorded double-
digit gains for the first six months of the year.

Health care stocks were generally disappointing during the first half of the
year. Guidant and Medtronic performed exceptionally well during the first three
months of the year, as did the Fund's hospital consolidator holdings, OrNda
Healthcorp and Columbia/HCA. On the other hand, Genzyme was a disappointment,
suffering from FDA limitations on a new product introduction. Several HMOs,
including Humana, one of the Fund's holdings, preannounced disappointing second
quarter earnings, which they attributed to higher utilization trends and premium
pricing pressures. This led to underperformance of Humana, United Healthcare,
and PacifiCare Health Systems holdings in the second quarter. Profit taking
among pharmaceutical companies and signs of sector rotation also weakened


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

Weighting The proportion of a portfolio allocated to a specific security or
sector, i.e., a fund is said to be overweighted in a sector when that portion of
the portfolio is greater than the sector's general relationship to the market as
a whole.

Sector rotation A general movement of investments out of one sector of the
market into another that has become more attractive to investors.

Excess capacity Refers to underutilized manufacturing resources which generally
occurs when inventory levels exceed the demand for goods and services.

Bottom-up investing Security selection based on the specific fundamental merits
of individual issues. The opposite of "top-down" investing, which starts with
general economic trends, compares market sectors, and uses relative security
values to narrow the range of issues to examine.

health care stock performance.  We continue to monitor the fundamental outlook
for the HMO securities in a rapidly changing environment.

Excess capacity, inventory adjustments, and weaker demand for personal computers
and cellular phones led to mixed performance among technology stocks during the
first half of 1996. In this environment, our bottom-up selection process worked
in the portfolio's favor with stocks such as Microsoft, Computer Associates, and
EMC, which outperformed the market in the first quarter--and Sun Microsystems,
Intel Corp., and Oracle, which provided double-digit advances in the second
quarter. Other technology holdings, however, such as Lam Research and Seagate,
suffered from preannounced earnings disappointments, which negatively impacted
the portfolio. While we sold Micron at a profit, unfortunately we did so long
after the stock's heyday had passed. Among technology stocks, we remain focused
primarily on software, networking, and database management companies as the
fundamentals for these specific sectors continue to be attractive.

Despite strong gains in April and May, the Fund lagged the S&P 500 by nearly 300
basis points (3%) in June. Two notable underperformers were copy machine
companies, Alco Standard and Danka Business Systems, which faced unrelated
setbacks. Since their problems appear temporary and demand for both companies'
products and services remains robust, we are continuing to hold both stocks.

Throughout the first half of the year, we concentrated on risk management by
focusing on highly liquid securities and following our strict diversification
guidelines. Despite the strong performance of HFS, the stock also represented
one of our largest sales as we trimmed back to stay within our portfolio
management disciplines on individual security positions.

Going forward, we believe a low inflation environment and slow but steady
economic growth should provide a positive backdrop for growth stocks. No matter
how the economy unfolds, however, we will continue to use careful security
selection to seek long-term growth of capital.

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

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

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

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

INDEXED EQUITY FUND
================================================================================

Fund Highlights for the six months ended June 30, 1996

   . One-year total returns of 25.45% and 25.17% for Institutional Class and
     Service Class shares, respectively, as of 6/30/96

   . Institutional Class shares received a four-star overall rating from
     Morningstar, Inc.* as of 6/30/96

   . Fund returns closely tracked the S&P 500 Stock Index+

For the six-months ended June 30, 1996, the MainStay Institutional Indexed
Equity Fund returned 9.93% and 9.77% for Institutional Class and Service Class
shares, respectively. Over the same period, the S&P 500 returned 10.09% and the
average for funds in the Lipper(S) S&P 500 Index objective fund category
returned 9.83%. This performance helped the Fund's Institutional Class shares
earn a four-star overall rating from Morningstar, placing them among the top 33%
of their Morningstar universe, which consisted of 1,583 equity funds for the 3-
year period and 997 equity funds for the 5-year period ended 6/30/96.

After the stock market posted outstanding gains in 1995, many analysts expected
less-than-spectacular returns this year. At the end of the first half of the
year, however, the market already gained more than 10%. The driving force behind
last year's performance, strong corporate profits, showed little signs of
abating, despite scattered pockets of weakness. Although interest rates began to
edge higher, many investors appeared confident that the economy's "soft landing"
was a reality and that inflation would remain under control. Only at the very
end of June did we see any significant signs of impending inflation, as the
country approached full employment.

Small company stocks outperformed larger issues throughout the first half of the
year, leading the S&P 500 Stock Index to underperform the NASDAQ Composite Index
and mutual funds that were heavily invested in smaller issues. During the
reporting period, the NASDAQ Composite Index returned 12.63%.

The Indexed Equity Fund does not seek to benefit from shifting investor
preferences among small-, medium-, and large-capitalization issues. Instead, it
seeks to track the performance of the S&P 500 Stock Index, which consists
primarily of larger issues representing about two-thirds of the capitalization
of the stock market as a whole. Since the Fund incurs fees and expenses that the
Index does not, investors should anticipate trailing the Index by a small
margin.

The Fund seeks to remain as fully invested as possible at all times, to give
investors broad exposure to the companies that make up the S&P 500 Stock Index.
The Fund also seeks to invest in stocks in the same proportions as they are
invested in the Index. As a result, investors may experience greater gains or
losses from the price movements of sectors or securities with greater
representation in the Index.

"Soft landing" A curb on economic growth or other Federal Reserve action that is
sufficiently gradual to not create major disruptions or distortions in the
equity and fixed-income markets.

Inflation An increase in the supply of money relative to available goods and
services, resulting in higher prices or a rising "cost of living."

Full employment The level of employment that results from the efficient use of
the civilian labor force, after allowances are made for the normal rate of
unemployment due to dynamic changes and the structural conditions of the
economy.  For the U.S., full employment is thought to exist when between 94%-95%
of the labor force is employed.

Capitalization The amount of outstanding equity a company has issued. Companies
may vary greatly in the amount of equity capital they have raised, and their
capitalization may change with new issues or stock repurchases.

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

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

During the reporting period, one of the best performing industries in the S&P
500 Stock Index was the shoe industry, which was propelled upward by Nike's 48%
return, to finish the first half of the year with a 41.75% gain. Since this
industry only represented 0.4% of the S&P 500, however, its impact on the Fund's
performance was very modest. The Coca-Cola Company and PepsiCo, with respective
returns of 32.4% and 27.4%, had a greater impact, as they pushed the soft drink
beverage industry sector of the S&P 500 up 30.8%. This sector accounts for 3.5%
of the Index. In the first half of the year, the worst performing sectors in the
Index were trucking company stocks (-16.3%), home-building stocks (-12.2%), and
HMOs (-12.1%), which represented 0.043%, 0.043%, and 0.372% of the Index,
respectively.  These small weightings served to moderate the negative impact
these laggards had on the portfolio as a whole.

*   Morningstar, Inc. is an independent fund performance monitor. Its ratings
    reflect historic risk-adjusted performance, which does not include sales
    charges, and may change monthly. Its ratings of 1 (low) and 5 (high) stars
    are based on a fund's 3-, 5- & 10-year average annual returns with fee
    adjustments, and a risk factor that reflects fund performance relative to 3-
    month Treasury bill monthly returns. A one-year rating is calculated using
    the same methodology, but is not a component of the overall rating. As of
    6/30/96, the individual 1, 3 and 5 year ratings for the MainStay
    Institutional Indexed Equity Fund was 5, 4 and 4 stars, respectively. For
    the one-year period, the Fund was rated among 2,882 funds in the equity
    category. Only 10% of the funds in an investment category may receive 5
    stars, 22.5% may receive 4 stars and 35% may receive 3 stars. Ratings
    reflect Institutional Class performance only. Service Class shares,
    introduced January 1, 1995, will not be rated by Morningstar until they have
    a three year operating history.

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

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

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

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

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

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

Fund Highlights for the six months ended June 30, 1996

  . One-year total returns of 22.53% and 21.99% for Institutional Class and
    Service Class shares, respectively, as of 6/30/96

  . Outpaced the MSCI EAFE Index* and its average peer fund in the Lipper(S)
    international fund category for the one-year and six-month periods ended
    6/30/96

  . Benefited from country allocation and selective currency management
    strategies
 
For the six months ended June 30, 1996, the MainStay Institutional International
Equity Fund had total returns of 8.50% and 8.23% for Institutional Class and
Service Class shares, respectively. These results were ahead of the average
Lipper international fund, which returned 8.02% for the same period--and well
ahead of the Morgan Stanley Capital International (MSCI) EAFE Index, which
returned only 4.67%.

In the first quarter of 1996, the Fund benefited from international
diversification in two of the better performing international markets--Hong Kong
in Asia, and France in Europe. With its close ties to the growing U.S. economy,
Hong Kong's market was up 11.7%, and France continued its interest-rate
reductions, which resulted in a stock market  gain of 11.6% (both in local
terms). In the second quarter, the Fund had over 11% of its investments in the
three top-performing equity markets--Spain, Italy, and Norway with market
increases of 10.9%, 10.8% and 8.8%, respectively. These markets rallied as a
result of declining trends in local interest-rates. Japan, the largest equity
market outside of the U.S., performed in line with the average of international
markets in the second quarter, but signs of economic recovery in Japan caused
Japanese equities to surge 43.5% over the 12 months ended June 30, 1996. The
weakest of the developed European markets was the U.K., which was up only 2.6%
over the reporting period.  The Fund benefited from substantial investments in
Japan and modest positions in the U.K. Singapore was the weakest developed
market, overall, down 3.4% for the first six months of 1996, but its relatively
small weighting in the portfolio moderated its negative impact on returns.

Latin America and other emerging markets were strong performers in the second
quarter, causing the Fund to lag other funds that invested there. As of June 30,
1996, the Fund's portfolio did not include any investments in emerging markets.
Given the instability and volatility of emerging markets, we prefer to forego
profits on occasion rather than expose investors to undue risk.  We also use
strict liquidity and diversification disciplines to help manage risks the
portfolio may encounter.

Throughout the first half of the year, the Fund also benefited from our currency
management strategies. Selective hedging helped protect the portfolio as
expensive foreign currencies declined relative to the U.S. dollar. During the
six-month reporting period, the Japanese yen and the German mark both declined
about 6.0%, and the Swiss franc dropped 8.0% relative to the U.S. dollar. On the
other hand, the Italian lira and U.K. pound increased relative to the U.S.
dollar. Our currency management strategies in these countries allowed us to
capture most of the gains. The Australian dollar gained 5.0% relative to the
U.S. dollar in the first quarter and remained flat in the second. Since we were
not hedged in Australian dollars, we captured the entire gain in that portion of
our portfolio.

International diversification Purchasing securities in several international
markets, which may react differently to economic, monetary, and market trends.
This diversification may provide opportunities for investors to pursue higher
returns while seeking to manage the risks of domestic investments.

Emerging markets Underdeveloped markets with less capital, or influence than the
leading markets in the world economy. While emerging markets may sometimes offer
greater growth potential than established markets, they generally carry greater
risks.

Liquidity The ability of a security to be readily traded or exchanged for cash.
Generally speaking, the larger an issuer's capitalization, the more liquid its
securities are likely to be.

Currency management/hedging The process of managing or "hedging" the risks
associated with owning securities denominated in different currencies, the
relative values of which may change at any time. There can be no assurance that
currency hedging will be beneficial to investors.

As we enter the second half of the year, the threat of Federal Reserve
tightening may increase the risk of foreign currencies declining against the
U.S. dollar. Should that occur, diversification into developed markets whose
central banks act independently of the Fed may again look attractive. With this
possibility in mind, we hold diversified positions in both Europe and Asia. We
find Austria, Italy, Spain, and France attractive because we anticipate
continued interest rate reductions in the face of mounting recessionary concern.
In Asia, we remain interested in Singapore, which we believe is now
significantly undervalued. In Japan, persistent government efforts to promote
economic growth continue to provide a positive outlook. We are emphasizing
energy and natural resources through investments in Norway (Norsk Hydro), the
Netherlands (Royal Dutch Petroleum), Australia (mining and metals), and New
Zealand (forest products) due to their attractive pricing.

The Fund is currently positioned across a broad array of developed equity
markets, with a tilt in favor of major Asian and peripheral European markets
over core European equity markets. The Fund continues to pursue long-term growth
of capital with an acceptable level of risk using a "country-first" approach. We
seek to identify the most promising markets outside the U.S. and equities in
each market with attractive growth potential. Current income is a secondary
objective of the Fund.

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.

MULTI-ASSET FUND
- --------------------------------------------------------------------------------


Fund Highlights for the six months ended June 30, 1996

 . One-year total returns of 21.43% and 21.13% for Institutional Class and
   Service Class shares, respectively, as of 6/30/96

 . Both share classes outperformed the Lipper+ flexible portfolio fund average
   for the six-month and 1-year periods ended 6/30/96

 . Institutional Class shares received a four-star overall rating from
   Morningstar, Inc.* as of 6/30/96

For the six months ended June 30, 1996, the MainStay Institutional Multi-Asset
Fund returned 8.14% and 7.97% for Institutional Class and Service Class shares,
respectively. Both share classes outperformed the average Lipper flexible
portfolio fund, which returned only 5.52% for the same period.

The Fund's Institutional Class shares also received a four-star overall rating
from Morningstar, Inc., placing them among the top 33% of the Morningstar
universe, which consisted of 2,848 hybrid funds for the 3-year and 1,696 hybrid
funds for the 5-year period ended 6/30/96.

With a continuing bull market for stocks in the first half of 1996, bonds
suffered some serious setbacks. Rising interest rates pummeled bond prices,
while equity prices rose based on strong corporate profits. The Multi-Asset Fund
was well-positioned to take advantage of the discrepancy in returns between
stocks and bonds. The Fund remained at its maximum weight in stocks (80%) and
minimum weight in bonds (10%) throughout the first half of the year.

The yield-to-maturity on the Salomon Brothers Broad Investment Grade (BIG) Bond
Index++ has ranged between 6% and 7% throughout most of the first half of the
year. While bond yields edged higher during these six months, this level is
still relatively low when compared to yields over the last twenty-year period.
In managing the Fund, we use quantitative models to govern the allocation
between stocks, fixed-income securities and money market instruments. These
models have identified stocks as a more attractive investment on a risk-adjusted
basis during the first half of the year. This has proven to be very beneficial
to the Fund. The bond market, as represented by the Salomon BIG Index lost 1.26%
in the first half of the year, while the S&P 500(S) Stock Index surged 10.09%.

Some of the Fund's equity exposure was obtained abroad. 5% of the Fund's net
assets were allocated to German securities in the first four months of the year.
During that period, Germany's DAX Index was up 11.87% (in local terms). An
additional 5% was invested in the British FTSE-100 Stock Index+++ in April,
which rose 3.59% (in local terms) that month. Smaller investments in Australia
and France in the second quarter did not pay off, as U.S. stocks outperformed
these markets. The investment in foreign securities provided opportunity not
only for return enhancement, but also the opportunity to reduce price
volatility. This is because the returns of foreign stocks are not highly
correlated with those of domestic stocks and bonds. Allocations to such
diversifying assets may work to reduce the Fund's overall volatility, which is
one measure of portfolio risk.

James A. Mehling, CFA
Portfolio Manager

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

    Past performance is no guarantee of future results.
 
*   Morningstar, Inc. is an independent fund performance monitor. Its ratings
    reflect historic risk-adjusted performance, which does not include sales
    charges, and may change monthly. Its ratings of 1 (low) and 5 (high) stars
    are based on a fund's 3-, 5- & 10-year average annual returns with fee
    adjustments, and a risk factor that reflects fund performance relative to 3-
    month Treasury bill monthly returns. A one-year rating is calculated using
    the same methodology, but is not a component of the overall rating. As of
    6/30/96, the individual 1, 3 and 5 year ratings for the MainStay
    Institutional Multi-Asset Fund was 4, 4 and 4 stars, respectively. For the
    one-year period, the Fund was rated among 5,076 funds in the hybrid
    category. Only 10% of the funds in an investment category may receive 5
    stars and 22.5% may receive 4 stars. Ratings reflect Institutional Class
    performance only. Service Class shares, introduced January 1, 1995, will not
    be rated by Morningstar until they have a three year operating history.
    
(S) Lipper Analytical Services Inc. is an independent monitor of mutual fund
    performance. Results do not reflect any deduction of sales charges and are
    based on total returns with capital gains and dividends reinvested.

Weight The proportion of a portfolio allocated to a specific security, sector,
or asset class.

Yield-to-maturity The rate of return an investor will earn if a fixed-income
security is held to maturity, taking into account a variety of factors,
including the purchase price, redemption value, time to maturity, coupon yield,
and the time between interest payments.

Risk-adjusted returns When absolute returns in a security, portfolio, or asset
class are adjusted for the risk required to achieve them. Risk may be determined
by comparing performance over time with a benchmark (such as short-term Treasury
bills).

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

Volatility Fluctuations in the price of a security, sector, portfolio, currency,
or asset class over time, either on an absolute basis or in relation to other
assets, markets, or currencies. The degree and frequency of such variations
determines the relative volatility of the asset or currency under consideration.

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

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

     Past performance is no guarantee of future results. Investment return and
     principal value will fluctuate so that upon redemption, shares may be worth
     more or less than their original cost.
 
     The Institutional Class shares are sold with no sales charge. The Service
     Class shares, first offered 1/1/95, are sold with no initial or contingent
     deferred sales charge, but are subject to an annual shareholder service fee

VALUE EQUITY FUND

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

Fund Highlights for the six months ended June 30, 1996

 . One-year total returns of 20.45% and 20.10% for Institutional Class and
   Service Class shares, respectively, as of 6/30/96

 . Underperformed the S&P 500 Stock Index* and the average Lipper(S) growth and
   income fund for the six-month and 1-year periods ended 6/30/96

 . Institutional Class shares received a five-star overall rating from
   Morningstar, Inc.+ as of 6/30/96

 . Positive results in retailers, tobacco stocks, and consumer-related issues

For the six months ended June 30, 1996, the MainStay Institutional Value Equity
Fund returned 7.69% and 7.55% for Institutional Class and Service Class shares,
respectively. These results trailed the S&P 500 Stock Index, which returned
10.09%, and the average Lipper growth and income fund, which returned 9.24%,
over the same period. Nevertheless, the Fund earned Morningstar's highest
overall ranking of five stars, placing it among the top 10% of funds in its
Morningstar universe. The Value Equity Fund's individual Morningstar ratings for
the three- and five-year periods ending 6/30/96 were 4 stars and 5 stars,
respectively, out of a universe of 1,583 and 997 funds in the equity category
for their respective periods.

The Fund had a strong first quarter and a challenging second quarter. During the
first quarter, the long-awaited signs of an economic recovery began to emerge,
with improvements in auto sales, housing activity, and retail sales. These signs
led to rising interest rates, prompting first-quarter corrections in financials,
consumer nondurables, utilities, and healthcare. In the second quarter, 30-year
Treasury yields pierced the 7% level, spreading the earlier corrections into
economically sensitive issues. The stock market also underwent a rotational
correction when prospects for rising profits came into question as the economy
picked up.

Chemical issues such as Lyondell, Georgia Gulf, and Dow Chemical, which helped
overall performance in the first quarter, were particularly weak in the second.
Despite careful selection and screening of financial issues, regional banks such
as Wells Fargo and First Bank System underperformed as interest rates rose.
Aetna's buyout announcement of U.S. Healthcare confirmed the consolidation trend
in the HMO industry. We had previously purchased U.S. Healthcare based on
attractive earnings growth, management ownership, and strong asset value, and we
profited from the acquisition announcement. Nevertheless, our holdings in Humana
and FHP International suffered in the subsequent correction, as earnings
prospects for the industry came under pressure.



Economic recovery A general improvement in formerly weak fundamental factors
underlying a country's gross domestic product, which may include factory output,
sales, productivity, employment, and relative currency values.

Sector rotation A general movement of investments out of one sector of the
market into another that has become more attractive to investors.

Correction A shift in securities prices which brings them more in line with
historically appropriate levels.

Bottom-up investing Security selection based on the specific fundamental merits
of individual issues. The opposite of "top-down" investing, which starts with
general economic trends, compares market sectors, and uses relative security
values to narrow the range of issues to examine.

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

+   Morningstar, Inc. is an independent fund performance monitor. Its ratings
    reflect historic risk-adjusted performance, which does not include sales
    charges, and may change monthly. Its ratings of 1 (low) and 5 (high) stars
    are based on a fund's 3-, 5- & 10-year average annual returns with fee
    adjustments, and a risk factor that reflects fund performance relative to 3-
    month Treasury bill monthly returns. A one-year rating is calculated using
    the same methodology, but is not a component of the overall rating. As of
    6/30/96, the individual 1, 3 and 5 year ratings for the MainStay
    Institutional Value Equity Fund was 3, 4 and 5 stars, respectively. For the
    one-year period, the Fund was rated among 2,882 funds in the equity
    category. Only 10% of the funds in an investment category may receive 5
    stars, 22.5% may receive 4 stars and 35% may receive 3 stars. Ratings
    reflect Institutional Class performance only. Service Class shares,
    introduced January 1, 1995, will not be rated by Morningstar until they have
    a three year operating history.

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

     Shifting earnings and sector rotation produced mixed results among the
     Fund's capital goods/technology stocks. In the first quarter, IBM was
     strong while Xerox, Lockheed Martin, McDonnell Douglas, and Intel were
     weak. In the second quarter, we sold Intel at a gain, felt the impact of
     weakness at IBM, and benefited from strengths at Xerox, Lockheed Martin,
     and McDonnell Douglas.

     Stop & Shop, which we purchased based on its restructuring, insider
     ownership, and attractive value, benefited the Fund handsomely when the
     same fundamentals led to a takeover announcement in the first quarter.
     During the second quarter, our careful "bottom-up" security selection and
     review process paid off in a number of areas. With an improved outlook in a
     class action suit, tobacco stocks, including Philip Morris and RJR Nabisco,
     exhibited strong performance. Retail stocks such as Dillard, J.C. Penney,
     and Federated Department Stores strengthened the Fund's performance.
     Several other consumer-related stocks, including Premark, Kroger, and
     American Stores, made positive contributions to the portfolio during the
     first six months of 1996. Premark's contribution was decisively positive
     when it spun off its Tupperware business in the second quarter to realize
     greater value for its shareholders.

     Despite short-term challenges, our outlook remains unchanged. We continue
     to believe that metals, papers, and consumer cyclicals, such as auto parts
     and building materials, offer attractive valuations if the economy
     improves. With the recent rise in interest rates, we also anticipate
     opportunities to add to our financial positions at attractive valuations.
     Overall, we believe these areas of corporate America are best positioned
     for earnings improvements over the next 12 months. If the economy improves
     as we expect, we believe the Fund may benefit as undervalued issues move
     toward their full market potential.

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

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

     Past performance is no guarantee of future results. Investment return and
     principal value will fluctuate so that upon redemption, shares may be worth
     more or less than their original cost.
 
     The Institutional Class shares are sold with no sales charge. The Service
     Class shares, first offered 1/1/95, are sold with no initial or contingent
     deferred sales charge, but are subject to an annual shareholder service fee

Bond Fund
- --------------------------------------------------------------------------------


Fund Highlights for the six months ended June 30, 1996

 . One-year total returns of 4.38% and 4.09% for Institutional Class and Service
   Class shares, respectively, as of 6/30/96

 . Institutional Class shares earned a four-star overall ranking from
   Morningstar, Inc.* as of 6/30/96

 . Performance benefited from our neutral duration position, security selection
   in the mortgage market, and the addition of Yankee bonds

 . Exposure to mortgage securities negatively impacted the Fund's return

For the six months ended June 30, 1996, the MainStay Institutional Bond Fund
posted total returns of -1.83% and -1.93% for Institutional Class and Service
Class shares, respectively. These returns were relatively in line with the
Lehman Brothers Government/Corporate Bond Index+ return of -1.88%, but lagged
the average Lipper(S) intermediate U.S. Government fund, which returned -1.49%
for the reporting period.

Even though the Fund's short-term results were negative, the Fund earned an
overall four-star rating from Morningstar, Inc., placing it among the top 33% of
all funds in the Morningstar universe. The Bond Fund's individual Morningstar
ratings for the three- and five-year periods ending 6/30/96 were 3 stars and 4
stars, respectively, out of a universe of 889 and 464 funds in the fixed-income
category for their respective periods.

The economy experienced solid growth during the first six months of 1996. This
strength pushed yields higher in the bond market, which lowered prices and
contributed to negative returns in most bond sectors. In this difficult period,
only short-term and high-yield bonds posted positive returns.

During the first quarter, the Fund's maturity was kept neutral to the Lehman
Brothers Government/Corporate Bond Index due to the conflicting indicators in
the economy.  Our decision to keep the Fund's maturity neutral to the Index
neither helped nor hurt performance.  During the volatile second quarter,
however, our maturity decisions contributed positively to performance.

In the first quarter, mortgage-backed securities offered attractive valuations,
yet ended the quarter hurting the Fund's overall performance.  Since the Index
does not contain mortgage-backed securities, these holdings also caused the Fund
to slightly lag behind the Index performance. In the second quarter, however, we
added higher-yielding, high-quality short-term mortgage assets, which helped
boost the Fund's performance. We also included Yankee bonds in the Fund during
the first half, which helped our returns, as investors began to recognize values
in this under-followed sector.

In Treasuries, newer issues held in the portfolio added value compared to older
issues in the first quarter. This trend reversed during the second quarter, as
did we.  As a result, the older issues added value during this period. We
believe the trend will yet again reverse during the third quarter and, if it
does, we intend to swap our older issues into newer ones as the quarter unfolds.

The Fund continues to stress quality, as the portfolio ended the first half of
the year with an average weighted quality rating of AA+**.

Portfolio Managers


Yield The income per share (or current value of a security) paid to investors
over a specified period of time as a percentage of the cost of the security.

Maturity The termination date of an obligation of the length of time a fixed-
income security is required to pay interest. The maturity of a portfolio or
Index generally refers to the average of the maturities of the individual
securities in it.

Mortgage-backed securities Securities representing interests in "pools" of
mortgages in which principal and interest payments by the holders of underlying
fixed- or adjustable-rate mortgages are, in effect, "passed through" to
investors (net of fees paid to the issuer or guarantor of the securities).

Yankee bonds Dollar-denominated bonds issued in the United States by foreign
banks and corporations when U.S. rates are more favorable than those available
in local foreign markets.

     Past performance is no guarantee of future results.
 
*    Morningstar, Inc. is an independent fund performance monitor. Its ratings
     reflect historic risk-adjusted performance, which does not include sales
     charges, and may change monthly. Its ratings of 1 (low) and 5 (high) stars
     are based on a fund's 3-, 5- & 10-year average annual returns with fee
     adjustments, and a risk factor that reflects fund performance relative to 
     3-month Treasury bill monthly returns. A one-year rating is calculated 
     using the same methodology, but is not a component of the overall rating.
     As of 6/30/96, the individual 1, 3 and 5 year ratings for the MainStay
     Institutional Bond Fund was 3, 3 and 4 stars, respectively. For the one-
     year period, the Fund was rated among 1,487 funds in the fixed income
     category. Only 10% of the funds in an investment category may receive 5
     stars, 22.5% may receive 4 stars and 35% may receive 3 stars. Ratings
     reflect Institutional Class performance only. Service Class shares,
     introduced January 1, 1995, will not be rated by Morningstar until they
     have a three year operating history.

**   Standard & Poor's considers debt rated AA to have a very strong capacity to
     pay interest and repay principal and differs from the highest rated issues
     only in a small degree. The plus sign shows relative standing within the
     major rating category of AA. This rating is based solely on the

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

Fund Highlights for the six months ended June 30, 1996

 . One-year total returns of 4.31% and 3.94% for Institutional Class and Service
   Class shares, respectively, as of 6/30/96

 . For the six months ended 6/30/96, both share Classes outperformed the average
   Lipper+ general U.S. Government fund

 . The Fund tracked the Salomon Brothers Broad Investment Grade Index*
   throughout the reporting period

For the six months ended June 30, 1996, the MainStay Institutional Indexed Bond
Fund returned -1.82% and-1.91% for Institutional Class and Service Class shares,
respectively. Even though returns were negative, both share classes outperformed
their peers, with the average Lipper general U.S. Government fund posting a 
- -2.62% return over the same period.

Rising interest rates made the first six months of 1996 a challenging period for
fixed-income investors. The aggregate bond market, as represented by the Salomon
Brothers Broad Investment Grade (BIG) Index, fell 1.26% during the reporting
period. Most of the damage occurred in the first quarter, when the Index
declined 1.75%. In the second quarter, fixed-income prices generally fell, but
principal income brought the Salomon BIG Index's total return up 0.49% at the
end of the first half of the year.

For the first six months of 1996, the only sector of the Salomon BIG Index to
post a gain -- albeit a small one of just 0.30% -- was the mortgage sector.
Since mortgage securities tend to have a much lower duration than most other
sectors of the bond market, they tend to be less sensitive to interest rate
changes.

Investment-grade bonds have been battered by a continually strengthening
economy, which has driven inflation expectations and interest rates higher. Non-
investment-grade bonds, on the other hand, thrive under these conditions, as
credit risk becomes  less threatening. The Lipper high current yield category,
for example, rose almost 5% in the first six months of 1996, while higher
quality corporate issues declined substantially. The high-grade corporate sector
of the Salomon BIG Index lost 4.7% during the reporting period. This contributed
to the Fund's negative performance in the first half since the Indexed Bond Fund
invests only in investment-grade bonds that are included in the Index. These
securities are typically less risky than high yield "junk" bonds, which tend to
experience much wider swings in returns.

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

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

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

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

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

International Bond Fund
================================================================================

Fund Highlights for the six months ended June 30, 1996

 . One-year total returns of 11.77% and 11.40% for Institutional Class and
   Service Class shares, respectively, as of 6/30/96

 . Outperformed the average Lipper* general world income fund for the six-month
   and one-year periods ended 6/30/96

 . Favorable results from country allocation, currency management, and maturity
   exposure

For the six-month period ended June 30, 1996, the MainStay Institutional
International Bond Fund provided total returns of 5.02% and 4.85% for
Institutional Class and Service Class shares, respectively. These results placed
both of the Fund's share Classes well ahead of the average Lipper general world
income fund, which returned only 1.69%. The Fund also outpaced the Salomon
Brothers Non-U.S. Dollar World Government Bond Index,+ which returned -1.30%
over the reporting period.

Our strong performance in the first half of the year resulted from a combination
of factors, including fruitful decisions on country allocation, currency
management, and maturity selection. Regarding country allocation, our best
decision was to emphasize European bonds, particularly in peripheral European
markets such as Sweden and Italy which were up 6.5% and 10.2% respectively, both
in local terms. We also limited our exposure to one of the worst-performing bond
markets, Japan, which returned less than 1% over the same period.

Latin America and other emerging markets were strong performers in the second
quarter. As of June 30, 1996, the Fund's portfolio did not include any
investments in emerging markets. Given the instability and volatility of
emerging markets, we prefer to forego profits on occasion rather than expose
investors to undue risk. The Fund also uses strict liquidity and diversification
disciplines to help manage risks the portfolio may encounter.

On the currency management front, the Fund benefited from our decision to
selectively hedge against foreign currency declines, as several currencies
continued to drop against the U.S. dollar. Out of our universe of 14 bond
markets, only four (Italy, U.K., Sweden, and Australia) were associated with
rising currencies against the U.S. dollar. Fortunately, the Australian dollar
was up 5.0%, and since we decided not to hedge our Australian bond holdings, the
Fund captured the gains. In the second quarter, the Fund wisely moderated
hedging activity in the Italian lira, U.K. pound, and Swedish krona, allowing us
to capture most of the gains in those currencies. By actively hedging other
European currencies, however, we avoided significant currency losses in bonds in
core European countries.

Maturity management benefited the portfolio in the first quarter, when we
emphasized short- and intermediate-term securities, while many markets
experienced vicious sell-offs in longer-maturity bonds. Our strategy provided
opportunities to purchase longer-maturity bonds at attractive prices during the
second quarter. These longer positions brought us to a neutral duration, which
helped the portfolio as we entered the third quarter.

Looking ahead, the Fund continues to favor high yielding European bond markets,
such as Italy, Spain, and Sweden at the expense of markets with low yields, such
as Japan and Switzerland. Recently, the Fund has been purchasing bonds in the
U.K., where yields have finally risen to attractive levels. Since we anticipate
continued appreciation in the U.S. dollar, we are seeking to help protect the
portfolio against further declines in foreign currencies.

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

Liquidity The ability of a security to be readily traded or exchanged for cash.
Generally speaking, the larger the capitalization of an issuer, the more liquid
its securities are likely to be.

International Diversification Purchasing securities in several international
markets, which may react differently to economic, monetary, and market trends.
This diversification may provide opportunities for investors to pursue higher
returns while seeking to manage the risks of domestic investments.

Currency management/hedging The process of managing or "hedging" the risks
associated with owning securities denominated in different currencies, the
relative values of which may change at any time. There can be no assurance that
currency hedging will be beneficial to investors.

Maturity management Purchasing securities of selected maturities to shorten or
lengthen the duration of a portfolio. Duration is a measure of average maturity,
which adjusts for the time value of the payments investors will receive and
which takes into account interest payments as well as principal payments.

   appreciation and dividends or interest. Total returns shown herein include
   the change in share price and reinvestment of capital gains distributions and

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


Fund Highlights for the six-months ended June 30, 1996
 . One-year total returns of 5.28% and 5.02% for Institutional Class and Service
   Class shares, respectively, as of 6/30/96

 . Six-month performance lagged the Lipper+ institutional money market fund
   average

The MainStay Institutional Money Market Fund provided total returns of 2.49% and
2.37% for Institutional Class and Service Class shares, respectively, for the
six-month period ended June 30, 1996. This compared with a 2.54% return for the
average Lipper institutional money market fund over the same period.

The first six months of the year proved to be very interesting for fixed-income
investors. During January, the Federal Reserve Board lowered its targeted
federal funds overnight lending rate by 25 basis points, based on a moderating
economic expansion and reduced inflationary pressures. By March, however, the
release of an exceptionally strong February employment report led some market
participants to believe they had underestimated the strength of the economy, and
some investor sentiment turned from bullish (expecting lower rates) to bearish
(expecting higher ones).

We believe this change in sentiment can best be seen by money market investors
in the 3-month and 1-year Treasury bill. At year-end 1995, these two instruments
had yields of 5.08% and 5.14%, respectively. Before the release of February
numbers the yields dropped below 5.00%. By the end of June, these rates rose to
5.16% and 5.68%, respectively. Yields continuously fluctuated throughout the
first half of the year, as the Federal Reserve, as well as investors, kept a
sharp eye on all economic news. Many investors believed the Federal Reserve
Board would raise interest rates, but the Fed tightening never occurred.

In response to the market's interest-rate volatility, we shortened our average
maturity steadily throughout the six month period. The Fund's average maturity
was 55 days at the beginning of the year, 47 days at the end of the first
quarter, and 39 days at the end of the second quarter. Our target at the
beginning of the third quarter was 35 to 45 days, which is neutral, with a bias
toward Fed tightening.

In addition to duration management, we also continued to comb the money market
subsectors for attractive opportunities. We found value in both bankers'
acceptances and loan participations. We also saw value in the short corporate
subsectors, however, additions of these to the portfolio have been light because
of a lack of supply.

For the remainder of the year, we believe Fed activity to be modest, with a
tightening move being the most likely course of action. Consequently, we expect
to keep our average maturity in the 35 to 45 day range until market fundamentals
change.

Portfolio Manager

Basis point One hundredth of one percent in the yield of an investment. So 100
basis points equals 1.00%.

Fed tightening A move by the Federal Reserve Board to control economic growth by
raising the interest rates on federal funds. Depending on the desired effect,
the Fed's open market committee sells short-, intermediate-, or long-term
maturities.

Duration A measure of average maturity, which adjusts for the time value of the
payments investors will receive and which takes into account interest payments
as well as principal payments.

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

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

     The Money Market Fund-Institutional Class had a 7- day effective yield of
     5.07% and a 7-day average yield of 4.95%, both as of 6/26/96. The Money
     Market Fund-Service Class had a 7-day effective yield of 4.81% with a 7-day
     average yield of 4.70%, both as of 6/26/96. The Administrator has agreed to
     assume a portion of the expenses for these Funds. Had certain expenses not
     been assumed by the Administrator, the 7-day effective yield and the 7-day
     average yield would have been 4.89% and 4.78%, respectively, for the
     Institutional Class and 4.63% and 4.53%, respectively, for the Service
     Class.

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

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

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

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

Fund Highlights for the six months ended June 30, 1996

  . One-year total returns of 5.14% and 4.83% for Institutional Class and
    Service Class shares, respectively, as of 6/30/96

  . Institutional Class shares earned a four-star overall rating from
    Morningstar, Inc.* as of 6/30/96

  . Six-month performance of Institutional Class shares was ahead of the average
    Lipper(S) short-term investment grade debt fund while Service
    Class shares were slightly behind the average

For the six-month period ended June 30, 1996, the MainStay Institutional Short-
Term Bond Fund provided total returns of 1.34% and 1.14% for Institutional Class
and Service Class shares, respectively. These results were in line with or ahead
of the average Lipper short investment grade debt fund's return of 1.18% for the
same period. Both the Fund and its Lipper category peers lagged the Salomon 1-3
Year Treasury Index,++ which returned 1.47% for the first half of 1996.

The Fund's Institutional Class shares also received a four-star overall rating
from Morningstar, Inc., placing them among the top 33% of the Morningstar
universe, which consisted of 889 fixed-income funds for the 3-year and 464
fixed-income funds for the 5-year period ended 6/30/96.

With some investors anticipating changes in Federal Reserve policy, short-term
securities had a turbulent six months. Short-term interest rates rose 80 basis
points, which depressed the value of bonds in the portfolio. While the Fund held
Treasury securities during the first half of the year, it also owned asset-
backed securities and corporate bonds due to their attractive valuations. These
holdings contributed to the Fund's positive performance. During the second
quarter, higher-yielding, high-quality mortgage-related products were added to
the Fund's portfolio which also contributed positively to performance compared
to the Index.

The overall portfolio credit quality of the Fund at the end of the first half of
the year remained Agency rated, which is above AAA.***

Basis point One hundredth of one percent in the yield of an investment. So 100
basis points equals 1.00%.

Asset-backed securities Bonds or notes backed by loans or accounts receivable
(such as automobile loans, computer leases, or credit card debt), and often
"enhanced" by a letter of credit or insurance.

Mortgage-backed securities Securities representing interests in "pools" of
mortgages in which principal and interest payments by the holders of underlying
fixed- or adjustable-rate mortgages are, in effect, "passed through" to
investors (net of fees paid to the issuer or guarantor of the securities).

     Past performance is no guarantee of future results.

*    Morningstar, Inc. is an independent fund performance monitor. Its ratings
     reflect historic risk-adjusted performance, which does not include sales
     charges, and may change monthly. Its ratings of 1 (low) and 5 (high) stars
     are based on a fund's 3-, 5- & 10-year average annual returns with fee
     adjustments, and a risk factor that reflects fund performance relative to
     3-month Treasury bill monthly returns. A one-year rating is calculated 
     using the same methodology, but is not a component of the overall rating.
     As of 6/30/96, the individual 1, 3 and 5 year ratings for the MainStay
     Institutional Short-Term Bond Fund was 4, 4 and 4 stars, respectively. For
     the 1-, 3-, and 5- year periods, the fund was rated among 1,487 funds, 889
     funds and 464 funds, respectively, in the fixed income category. Only 10%
     of the funds in an investment category may receive 5 stars and 22.5% may
     receive 4 stars. Ratings reflect Institutional Class performance only.
     Service Class shares, introduced January 1, 1995, will not be rated by
     Morningstar until they have a three year operating history.

(S)  Lipper Analytical Services Inc. is an independent monitor of mutual fund
     performance.  Results do not reflect any deduction of sales charges and are
     based on total returns with capital gains and dividends reinvested.

++   The Salomon 1-3 Year Treasury Index is an unmanaged index generally
     considered representative of the U.S. short-term bond market.

***  Agency rating is above AAA. Currently, debt rated AAA has the highest
     rating assigned by Standard & Poor's. These ratings are based solely on the
     creditworthiness of the bonds in the portfolio and is not meant to
     represent the stability or safety of the Fund.

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

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

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

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

NOTES TO FINANCIAL STATEMENTS (Unaudited)
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 June 30, 1996 the Company has eleven separate investment portfolios: EAFE
Index Fund, Growth Equity Fund, Indexed Equity Fund, International Equity
Fund, Multi-Asset Fund, Value Equity Fund, Bond Fund, Indexed Bond Fund,
International Bond Fund, Money Market Fund and Short-Term Bond Fund
(individually or collectively referred to as a "Fund" or the "Funds").
 
  The International Bond Fund and the International Equity Fund commenced
operations on January 1, 1995.
 
  Each Fund currently offers two classes of shares as follows: Institutional
Class shares and Institutional Service Class shares. The distribution of
Institutional Service Class shares commenced on January 3, 1995. The Company
has adopted a Shareholder Services Plan with respect to the Institutional
Service Class of each Fund. The Institutional Class shares and Institutional
Service Class shares are substantially the same, except that the Institutional
Service Class shares bear the fees payable under the Shareholder Services Plan
at an annual rate of 0.25% of the average daily net assets of the outstanding
Institutional Service Class shares ("Shareholder Service Fee").
 
  The investment objectives for each of the Portfolios of the Company are as
follows:

NOTE 2--Significant Accounting Policies:
- -------------------------------------------------------------------------------
 
The following is a summary of significant accounting policies followed by the
Company:
 
                                      (A)
 
VALUATION OF FUND SHARES. The net asset value per share of each Class of
shares of each Fund is calculated on each day the New York Stock Exchange (the
"Exchange") is open for trading as of the close of regular trading on the
Exchange. The net asset value per share of each Class of shares is determined
by taking the assets attributable to that Class, subtracting the liabilities
attributable to that Class, and dividing the result by the shares of that
Class that are outstanding.
 
The Money Market Fund seeks to maintain a net asset value of $1.00 per share,
although there is no assurance that it will be able to do so.
 
                                      (B)
 
SECURITIES VALUATION. Portfolio securities of the Money Market Fund are valued
at their amortized cost, which approximates market value. The amortized cost
method involves valuing a security at its cost on the date of purchase and
thereafter assuming a constant amortization to maturity of the difference
between such cost and the value on maturity date.
 
  Portfolio securities of each of the other Funds are stated at value
determined (a) by appraising common and preferred stocks which are traded on
the New York Stock Exchange at the last sale price on that day or, if no sale
occurs, the mean between the closing bid price and asked price; (b) by
appraising common and preferred stocks traded on other United States national
securities exchanges or foreign securities exchanges as nearly as possible in
the manner described in (a) by reference to their principal exchange,
including the National Association of Securities Dealers National Market
System; (c) by appraising over-the-counter securities quoted on the National
Association of Securities Dealers NASDAQ system (but not listed on the
National Market System) at the bid price supplied through such system; (d) by
appraising over-the-counter securities not quoted on the NASDAQ system and
securities listed or traded on certain foreign exchanges whose operations are
similar to the U.S. over-the-counter market at prices supplied by a pricing
agent selected by a Fund's investment adviser if such prices are deemed to be
representative of market values at the regular close of business of the New
York Stock Exchange; (e) by appraising debt securities at prices supplied by a
pricing agent selected by a Fund's investment adviser, whose prices reflect
broker/dealer supplied valuations and electronic data processing techniques if
those prices are deemed by a Fund's investment adviser to be representative of
market values at the regular close of business of the New York Stock Exchange;
(f) by appraising options and futures contracts at the last sale price on the
market where any such option or futures are principally traded; and (g) by
appraising all other securities and other assets, including over-the-counter
common and preferred stocks not quoted on the NASDAQ system, securities not
listed or traded on foreign exchanges whose operations are similar to the U.S.
over-the-counter market and debt securities for which prices are supplied by a
pricing agent but are not deemed by a Fund's investment adviser to be
representative of market values, but excluding money market instruments with a
remaining maturity of sixty days or less and including restricted securities
and securities for which no market quotations are available, at fair value in
accordance with procedures approved by the Board of Directors. Money Market
instruments held by the Funds with a remaining maturity of sixty days or less
are valued by the amortized cost method which involves valuing a security at
its cost on the date of purchase and thereafter assuming a constant
amortization to maturity of the difference between such cost and the value on
maturity date.
 
  Events affecting the values of portfolio securities that occur between the
time their prices are determined and the close of the New York Stock Exchange
will not be reflected in the Funds' calculation of net asset values' unless a
Fund's investment adviser deems that the particular event would materially
affect net asset value, in which case an adjustment will be made.
 
                                      (C)
 
FEDERAL INCOME TAXES. Each of the Funds is treated as a separate entity for
Federal income tax purposes. The Company's policy is to comply with the
requirements of the Internal Revenue Code applicable to regulated investment
companies and to distribute all of the taxable income to the shareholders of
each Fund within the allowable time limits. Therefore, no Federal income or
excise tax provision is required.

                                                      INSTITUTIONAL FUNDS INC.
 
  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 are recorded on the ex-
dividend date. For the Money Market Fund, dividends are declared daily and
paid monthly. Each of the other Funds intends to declare and pay substantially
all of their net investment income and net realized gains no less frequently
than once a year. Income distributions and capital gain distributions are
determined in accordance with Federal income tax regulations which may differ
from generally accepted accounting principles.
 
                                      (E)
 
SECURITY TRANSACTIONS AND INVESTMENT INCOME. The Company records security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method and include gains
and losses from repayments of principal on mortgage related and other asset-
backed securities. Dividend income is recognized on the ex-dividend date and
interest income is accrued daily. Discounts on securities, other than short-
term securities, purchased for all Funds are amortized on the constant yield
method over the life of the respective securities or, in the case of a
callable security, over the period to the first date of call.
 
                                      (F)
 
ORGANIZATION COSTS. Organization costs for the International Bond Fund and the
International Equity Fund amounted to $61,000 for each Fund. Such costs are
being amortized over 60 months beginning January 1, 1995, the date such Funds
commmenced operations. In the event that any of the initial shares purchased
by affiliates of the Administrator are redeemed, proceeds of such redemption
will be reduced by the proportionate amount of the unamortized deferred
organizational expenses which the number of shares redeemed bears to the total
number of initial shares purchased.
 
                                      (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 allocations of direct expenses can otherwise fairly be
made.
 
  The investment income and expenses (other than expenses incurred under the
Shareholder Services Plan), and realized and unrealized gains and losses on
investments of a Fund are allocated to separate classes of shares based upon
their relative net assets on the date the income is earned or expenses and
realized and unrealized gains and losses are incurred.
 
                                      (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 period. The changes in net assets arising from
changes in exchange rates and the changes in net assets resulting from changes
in market prices are not separately presented. However, gains and losses from
certain foreign currency transactions are treated as ordinary income for
Federal income tax purposes.
 
                                      117
<PAGE>
 
NOTES TO FINANCIAL STATEMENTS (Unaudited) (Continued)
 
  Net realized gain (loss) on foreign currency transactions represents net
gains and losses on forward currency transactions, net currency gains and
losses realized as a result of differences between the amounts of security
sale proceeds or purchase cost, dividends, interest and withholding taxes as
recorded on the Fund's books, and the U.S. dollar equivalent amount actually
received or paid. Net currency gains or losses from valuing such foreign
currency denominated assets and liabilities at period-end exchange rates are
reflected in unrealized foreign exchange gains or losses.
 
  There are certain risks involved in investing in foreign securities that are
in addition to the usual risks inherent in domestic instruments. These risks
include those resulting from future adverse political and economic
developments and possible imposition of currency exchange blockages or other
foreign governmental laws or restrictions.
 
                                      (J)
 
REPURCHASE AGREEMENTS. At the time the Funds enter into a repurchase
agreement, the value of the underlying security, including accrued interest,
will be equal to or exceed the value of the repurchase agreement and, in the
case of repurchase agreements exceeding one day, the value of the underlying
security, including accrued interest, is required during the term of the
agreement to be equal to or exceed the value of the repurchase agreement. The
underlying securities for all repurchase agreements are held in a segregated
account of the Funds' custodian. In the case of repurchase agreements
exceeding one day, the market value of the underlying securities is monitored
by pricing the underlying securities daily.
 
  In the event of the bankruptcy of a counterparty, realization of the
collateral may be delayed or limited.
 
                                      (K)
 
FORWARD CONTRACTS. A 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. Forward contracts may be used for hedging purposes.
(see Note 5).
 
                                      (L)
 
FUTURES CONTRACTS. A futures contract is an agreement to purchase or sell a
specified quantity of an underlying instrument at a specified future date, or
to make or receive a cash payment based on the value of a securities index.
During the period the futures contract is open, changes in the value of the
contract are recognized as unrealized gains or losses by "marking to market"
such contract on a daily basis to reflect the market value of the contract at
the end of each day's trading. The Fund agrees to receive from or pay to the
broker an amount of cash equal to the daily fluctuation in the value of the
contract. Such receipts or payments are known as "variation margin". When the
futures contract is closed, the Fund records a realized gain or loss equal to
the difference between the proceeds from (or cost of) the closing transaction
and the Fund's basis in the contract. Futures contracts may be used for
hedging purposes. (see Note 5).
 
                                      (M)
 
MORTGAGE DOLLAR ROLLS. A mortgage dollar roll ("MDR") is a transaction in
which a Fund sells mortgage backed securities from its portfolio to a
counterparty from whom it simultaneously agrees to buy a similar security on a
delayed delivery basis. The MDR transactions of a Fund are classified as
purchase and sale transactions. The securities sold in connection with the MDR
are removed from the portfolio and a realized gain or loss is recognized.
These securities are included at market value in the portfolio of investments
and liability for such purchase commitments is included as payables for
investments purchased.
 
                                      (N)
 
SECURITIES LENDING. The Fund may lend its securities to broker-dealers and
financial institutions. The loans are secured by collateral at least equal at
all times to the market value of the securities loaned. The Fund may bear the
risk of delay in recovery of, or loss of rights in, the securities loaned
should the borrower of the securities fail financially. The Fund receives
compensation for lending its securities in the form of fees or it retains a
portion of interest on the investment of

any cash received as collateral. The Fund also continues to receive interest
and dividends on the securities loaned and any gain or loss in the market price
of the securities loaned that may occur during the term of the loan will be for
the account of the Funds.

At December 31, 1995, for Federal income tax purposes, capital loss
carryforwards, as shown in the table below, are available to the extent
provided by regulations to offset future realized gains of each respective
Fund through the years indicated. To the extent that these loss carryforwards
are used to offset future capital gains, it is probable that the capital gains
so offset will not be distributed to shareholders. Additionally, as shown in
the table below, certain Funds intend to elect, to the extent provided by
regulations, to treat certain qualifying capital losses that arose during the
year ended December 31, 1995 as if they arose on January 1, 1996.

The Multi-Asset Fund intends to elect to treat for Federal income tax purposes
approximately $1,641 of qualifying foreign exchange losses that arose during

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