To Our
Shareholders            An Economic Soft Landing Is Achieved in U.S.

                        The past year saw the continuation of a very good
                        economic environment for investors in both stocks and
                        bonds. The U.S. economic growth rate as measured by
                        Gross Domestic Product continued to slow throughout the

                        wanted growth to slow to a more moderate, sustainable

1995."                  the year at high levels. This in turn slowed order- and
                        production-driven demand from the manufacturing sector,
                        exerting further downward pressure on the growth rate,
                        supporting the cause for interest rate cuts, and helping
                        to keep inflation at bay.

                        Foreign Growth Remains Slow

                        Growth was also slow in the major foreign economies. In
                        Japan, though it appears that a turnaround from a four-
                        year recession has begun, difficulties in the banking
                        sector caused growth to remain subdued. In Europe, hopes
                        for an economic recovery were not met, in part due to
                        weak export activity resulting from strong currencies,
                        and in part as a result of European interest rate cuts
                        that came later than expected.

                        Stock and Bond Markets React

                        While the Federal Reserve actually increased rates as
                        late as February 1995, the domestic bond market had
                        begun to rally as early as November 1994 on the belief
                        that growth would slow enough to indicate a change in
                        monetary policy. The market was correct. The Fed's
                        February rate increase of 1/2 point was followed during
                        the year by two cuts of 1/4 point each in July and
                        December. Rates on Treasuries fell significantly during
                        this period, which drove dramatic price appreciation for
                        Treasuries. The prices in most other bond sectors
                        followed suit, with 1995 playing out to be one of the
                        strongest bull markets for bonds in history.

                        Backed by low interest rates and a strong bond market,
                        U.S. stocks reached all-time highs in 1995. The Dow
                        Jones Industrial Average made new highs almost daily,
                        hitting a peak of 5,216 and closing the year at 5,117,
                        and the S&P 500 rose 37.58%. In addition to support from
                        the bond market, stocks reacted to continued positive
                        earnings surprises, merger and consolidation activity,
                        an improving export picture and growing productivity and
                        efficiency throughout corporate America. Though stock
                        markets in economies such as Switzerland and Sweden
                        actually outperformed the U.S., the Morgan Stanley EAFE,
                        an index of European, Australian and Far East markets
                        was up only 11.21%. Positive, but nothing near the
                        stellar performance of domestic stocks.

                        Outlook for Economy, Markets Remains Positive

                        The forecast for the U.S. economy and markets appears
                        favorable, though both should be somewhat more moderate
                        than they were during the past year. Economic growth
                        will probably slow further because while employment and
                        personal income--two obviously important components of
                        demand--are steady, they are not strong enough to fuel
                        increases in demand-driven growth.

                        Even in the face of a slower economy, sales and earnings
                        remained strong through the end of 1995. The U.S. had
                        its biggest productivity gain on record in 1995 and
                        exports grew, aided in the early part of the year by a
                        weak dollar, which in turn created improvements in
                        trade. Going into 1996, we expect to see exports remain
                        strong, as U.S. businesses recognize that future growth
                        will come in part from operating in a global market.
                        This opinion is supported by the heavy outlays we've
                        seen for business equipment, which should further
                        enhance competitiveness, productivity and export
                        activity for the coming year.


                                                                               1

                        The Case for Value Investing

                        Because of uncertainty about the slowing in the economy
                        throughout 1995, growth investing, or buying stocks of
                        companies whose earnings growth rates can surpass that
                        of the economy, took the lead last year. By the same
                        token it was growth, rather than income, that led to the
                        dramatic appreciation of 1995's bond market. With both
                        markets currently at high levels in terms of price, we
                        believe we will see a return of superior performance
                        from value investing strategies. Value investing relies
                        on capturing appreciation by "buying well" and seeking
                        out fundamental values, rather than buying above-average
                        growth. Value investors like the MassMutual
                        Institutional Funds work to buy stocks and bonds that
                        are either temporarily out-of-favor with the markets, or
                        that offer opportunities that have not yet been
                        recognized by the investment community at large.

                        With stocks and bonds at highs and a domestic economy
                        that is likely to continue to slow, we expect both the
                        stocks and bond markets to return to more "normal"
                        activity in terms of returns and volatility. In this
                        type of environment, value investing should continue to
                        offer solid long-term results. Since security selection
                        should be very important in the coming year, your
                        portfolio managers will continue to rely upon hands-on
                        research and careful analysis in an effort to find the
                        best opportunities for investors.

                        longer-term interest rates continued to decline over the
                        majority of the year, rates for the extremely short-term
                        securities we focus on--which influence the amount of
                        income the Fund can provide--remained favorable, even
                        exceeding rates on longer-term issues at certain times

                        likelihood of the Federal Reserve's interest rate cuts.
                        By lengthening our maturity, we hoped to make use of
                        available higher current income levels for as long as
                        possible, expecting that debt issued after a rate cut
                        would offer lower income levels. This strategy benefited
                        the Fund by allowing us to maintain our income stream
                        while the market adjusted to the Fed's actions.

                        income. At this time, the Fund is focused on what is
                        known as Tier 2 commercial paper. Commercial paper--
                        which is one of the major classes of money market
                        securities--is very short-term debt issued by banks or
                        corporations which, in addition to paying interest, is
                        usually sold at a discount. It is typically a very safe
                        investment, issued by high quality firms and often
                        backed by a line of credit. Tier 2 paper pays slightly
                        higher income than Tier 1, which is one of the factors
                        that allows Prime Fund an income advantage over money
                        market funds. But along with that comes a margin of
                        slightly higher risk, requiring us to research potential
                        credit opportunities carefully to maintain the
                        portfolio's relative safety.

What is your outlook    The Fed eased, or lowered rates, twice in 1995 and may
for the Fund?           do so again in the first few months of 1996 depending on
                        the forecast for the economy. If it appears that the
                        economy has slowed too far, or if budget discussions are
                        finalized, another decline is a distinct possibility.
                        However, we believe that any further declines will not
                        be significant. In this environment, we are continuing
                        to extend maturities in an effort to make the most of
                        the current rates while maintaining an emphasis on
                        principal stability. Our outlook for the Fund remains
                        optimistic, though our performance as always will be
                        tied to any changes in the Federal Reserve's monetary
                        policy.

                          basis of relative value
              
How has the Fund per-   The Fund's performance was very strong, both on an
formed over the year?   absolute and historical basis. Throughout the year, the
                        Fund benefited from the continuation of a bond market
                        rally that began late in 1994, on expectations that the
                        Federal Reserve would ease monetary policy, and
                        accelerated when the Federal Reserve began cutting
                        interest rates in July 1995. Lower current rates make
                        existing bonds more attractive to investors and
                        benefited prices in nearly all sectors. Also within this
                        environment the yield curve, the difference in yield
                        available from bonds of different maturities, flattened.

What effect did the     The shape of the yield curve is a very important
flattening of the       determinant of our portfolio's positioning. When the
yield curve have on     yield curve flattens, investors are not being fully
the portfolio?          compensated for longer-term lending to bond issuers. So
                        in a flat curve environment, we typically shorten our
                        duration, since there is limited added value to be
                        gained from extending duration. To achieve a shortening,
                        we sold all of our position in Treasuries, reducing them
                        from approximately 50% of the portfolio at the beginning
                        of 1995 to 0% by year-end. Treasuries had appreciated
                        during the year so by selling, we took advantage of the
                        flattening yield curve and repositioned the portfolio to
                        reflect our desired shorter duration--0.73 years at 
                        year-end down, from 2.76 in December 1994.

What other strategic    In addition to income, our investment strategy is driven
moves did you make in   by a search for relative value in the bond market. As we
the portfolio?          did in Treasuries, we sold positions to take profits in
                        corporate bonds. Corporate bonds performed well
                        regardless of any pressures a slowing economy could have
                        potentially imposed on the companies that issued them.
                        We reduced our position in corporates by approximately
                        7% and invested the proceeds into short-maturity
                        commercial paper which, due to the shape of the yield
                        curve, had been offering yields that were--and still 
                        are--very attractive on a relative basis.

What areas of the       Because the Fund's strategy was designed to limit
market are you          volatility, we're continuing our policy of shortening
currently targeting?    average duration, or exposure to changes in interest
                        rates. As we sell securities to reflect our new target
                        duration, we've continued to invest in money market
                        securities. Our holdings in this area have increased
                        from 10.1% to 65.5% over the past year.

What is your outlook    We believe the Fund will continue to perform well in the
for the Fund?           coming environment. The market outlook for bonds remains
                        positive in light of low inflation and a healthy
                        economy. As we move through 1996, we will use the
                        direction of the yield curve as a guide to positioning
                        our portfolio, both in terms of sector allocation and
                        duration decisions. We expect that in the coming year,

                        our duration has allowed us to continue to track the
                        duration of the Lehman Government/Corporate Bond Index,
                        which is our benchmark. The portfolio's average duration
                        increased over the year from 4.90 years to 5.51 years.

What other strategic    During the year, the Fund grew from $194 million to $254
moves have you made     million in size. While this was due in part to asset
within the portfolio?   appreciation and in part to new investments, it required
                        a great deal of trading activity to become fully
                        invested. Over the year, we sold some of our Treasuries
                        as the market improved and increased our percentage
                        allocation in corporate bonds from 21.0% to 30.6%.
                        Corporates also performed well over the year due to
                        strong fundamentals and demand factors. Additionally, we
                        increased our holdings of mortgage-backed securities.
                        Though mortgages are typically sensitive to prepayment
                        risk, our well-seasoned, well-structured holdings
                        remained strong throughout the year's declines in rates.

What areas of the       As we believe the corporate market still offers strong
market are you          potential, though within a slowing economy, we're
currently targeting?    employing extensive credit research before investing in
                        corporate issues. We also continue to increase our
                        exposure to the mortgage-backed sector of the market,
                        especially in adjustable rate mortgages, where we're
                        finding particularly attractive pricing. Pricing remains
                        an important part of our investment strategy. We
                        continue to buy bonds across sectors wherever we believe
                        we've found appreciation potential through mispriced
                        issues. In terms of credit, while the Fund remains a
                        high quality portfolio, our sales of Treasuries--the
                        highest-rated securities we invest in--had the effect of
                        reducing the average rating of the portfolio slightly.

What is your outlook    This has been a dramatic year for the bond market and
for the fund?           the Fund. While current low inflation and slow to
                        moderate economic growth lead us to believe there is
                        still room for appreciation in the market, it would be
                        very difficult to imagine repeating 1995's performance.
                        Our outlook is for the extension of a positive market
                        environment, where income will again be an important
                        component of total return. Within this outlook, we
                        expect the Fund to continue to provide the potential for
                        high total return consistent with reasonable risk by
                        maintaining a diversified portfolio of high-quality
                        bonds.

MassMutual Balanced Fund - Portfolio Manager Report

What are the            The objectives and policies of the Fund are to:
investment objective
and policies for the    . achieve high total rate of return over the long term
MassMutual Balanced       consistent with the preservation of capital
Fund?
                        . invest in equity securities, fixed-income securities
                          and money market instruments

                        . manage the allocation of investments in three sectors
                          within the following ranges:

                        10%-45% Prime Sector
                        10%-25% Core Bond Sector
                        45%-65% Value Equity Sector

How has the Fund        On an absolute basis, the Fund has performed quite well,
performed over the      backed by the dramatic appreciation declining interest
year?                   rates sparked in both the stock and bond markets.
                        Because of the Fund's focus on preservation of capital,
                        however, it did not perform as well as some of its more
                        aggressive peers over this unusual time period. Though
                        it will tend to lag in strong bull markets, we believe
                        our strategy is prudent for long-term investors and that
                        it will outperform its peers over time.

Did your allocation     As stock prices climbed higher over the year, and
between stocks, bonds   dividend yields fell, we trended our equity position
and cash change over    down somewhat. Our stock holdings will normally fall
the year?               within a range of 45% to 65% of the portfolio. In the
                        beginning of the year, we were 50% invested in stocks.
                        By the end of 1995, they represented approximately 49%.
                        Our core bond holdings at the end of 1995 represented
                        12% of the portfolio, down from 16%. In bonds, a
                        flattening yield curve also indicated a shortening in
                        the average life of our portfolio. When the yield curve
                        is flatter, investors are typically not well-compensated
                        for extending into longer-maturity bonds. While this
                        excluded us from some of the appreciation in the bond
                        market, our bond portfolio performed well. Our
                        allocation decisions stem from a policy consistent with
                        preservation of capital. The remainder of the portfolio,
                        approximately 39% up from 34% a year ago, is invested in
                        short-term securities.

What strategic moves    Though our performance was held back somewhat by the
did you make within     fact that the value stocks we invest in were
the portfolio?          outperformed by growth issues, we benefited from the
                        strong relative performance of large cap stocks over the
                        year. During the year, we increased our exposure to
                        consumer non-durables, one of the best performing
                        sectors of the market. Our purchases here were in
                        businesses typically insulated from slowing economic
                        growth, and benefited the portfolio considerably. We
                        also increased our holdings in the very strong financial
                        services area. Our higher exposure to financial
                        services, both in banking and insurance, was another
                        plus for the Fund. In terms of bond holdings, we sold
                        some of our Treasuries as the market improved and
                        increased our percentage allocation in corporate bonds.
                        Corporates performed well over the year due to strong
                        fundamentals and demand factors. Additionally, we
                        increased our holdings of mortgage-backed securities.
                        Though mortgages are typically sensitive to prepayment
                        risk, our well-seasoned, well-structured holdings
                        remained strong throughout the year's declines in rates.

What is your outlook    An environment of low inflation, favorable interest
for the Fund?           rates and slow to moderate economic growth suggests the
                        continuation of decent markets for both stocks and
                        bonds. While results should remain positive, we expect
                        to see a return to more normal periods for both markets.
                        In stocks, we are positioning the Fund for greater
                        volatility and selectivity in the coming year; in bonds,
                        we expect income to again become the most consistent
                        component of total return. We believe the Balanced
                        Fund's conservative strategy should position it to
                        perform well during what we believe will be a more
                        typical market environment.

year?                   Typically, our value-oriented style has not outperformed
                        the broad market indices in years where absolute gains
                        have been as robust as in 1995. Over the long term,
                        however, our value strategy--focusing on dividend-paying
                        companies with strong balance sheets while their stocks
                        are selling at what we consider low prices--has been

                        companies were able to turn in earnings at levels more
                        typical of small company growth stocks, which drove
                        their prices up. The market's focus on large cap stocks
                        benefited the Fund.

What strategic moves    Though we make investments based on researching
have you made within    individual companies rather than their industry sectors,
the portfolio?          the biggest move we made over the year was increasing
                        our exposure to consumer non-durables, one of the best
                        performing sectors for the year. Our purchases here--in
                        Albertson's, a major grocery concern and several
                        consumer goods companies such as American Brands, Inc.,
                        and Kimberly-Clark Corporation--were in businesses
                        typically insulated from slowing economic growth, and
                        benefited the portfolio considerably. We also increased
                        our holdings in the very strong financial services area,
                        buying the stock of MBIA, Inc., a municipal bond insurer
                        and SAFECO Corporation, a large property and casualty
                        insurance firm. Our higher exposure to financial
                        services was another plus for the Fund--in fact, looking
                        back, we would have liked to have owned more. Over the
                        year, the size of the Fund has grown, and so has the
                        weighted average market capitalization. This was a third
                        benefit during a period of large cap leadership.

What segments of the    Our buying has currently shifted from consumer non-
market are you          durables to more cyclical companies. Because this area
currently targeting?    suffered price declines over the year as the market
                        favored sectors with more stable earnings, we've been
                        able to buy stocks at what we consider compelling
                        values. We are buying and looking to buy companies that
                        can benefit from lower basic materials costs and thus
                        improve their profit margins regardless of the slower
                        economy.

What is your outlook    After the past year, it's become more difficult to find
for the Fund?           reasonably-priced stocks, but with inflation and long-
                        term interest rates low, our outlook remains favorable.
                        We believe the coming year's market will be positive,
                        but that it will perform more like its historical
                        average than it did in 1995. We expect to see more
                        typical levels of volatility than last year's market.
                        During the past year, the broad market advanced
                        significantly. Going forward, we believe stock selection
                        will again become more important. That could benefit the
                        Fund in that strong stock selection is one of the major
                        advantages of a research-driven value strategy like
                        ours.

                                                                              35

How has the Fund        On an absolute basis, the Fund performed well, though it
performed over the      was a year during which the types of stocks we invest in
past year?              were somewhat out-of-favor with the market. As a value
                        investor, our focus is on companies whose stocks are
                        selling for less than we think they're worth--a strategy
                        that has been a prudent approach to managing risk and
                        capturing appreciation and income potential over time.
                        Partially due to the slowing of the economy, this year's
                        market was driven instead by growth stocks, or companies
                        whose earnings are growing faster than the economic
                        growth rate.

How did small cap       Small cap stocks are the sector of the market investors
stocks fare during      typically turn to for above-average returns as, though
the year?               they entail more risk, they have performed better than
                        larger company stocks over the course of market history.
                        Because of this year's extremely strong market--one in
                        which the Dow Jones Industrial Average rose from 3,834
                        to 5,117--investors in large cap stocks were rewarded at
                        levels usually reserved for smaller company investing.
                        Since 1995's market made it unnecessary to take on
                        additional risk to capture strong gains, large cap
                        stocks led their smaller counterparts throughout the
                        year.

What staegic moves      1995's market can be divided into two halves. Through

portfolio?              They became more volatile in the second half, when
                        financial services stocks began to perform well. While
                        technology stocks rarely pay dividends and so don't
                        usually meet our value guidelines, approximately 25% of
                        our portfolio was invested in financial services. Due to
                        merger and consolidation activity, many bank stocks were
                        driven higher. Insurance companies also performed well
                        for us in light of favorable interest rates and
                        relatively low casualty losses.

                        Beyond these themes, our purchases have been diverse. As
                        a bottom-up manager, we look for opportunities to buy
                        dividend-paying companies with strong balance sheets
                        across industry sectors. Though it's hard to buy stocks
                        at value prices during a strong market advance, we were
                        able to find opportunities in Atlantic Southeast
                        Airlines, Inc., an efficient small airline, Dallas
                        Semiconductor Corp., an industrial semiconductor
                        supplier, and Hudson Foods Inc., a poultry processor
                        with lucrative exposure to Pacific Rim countries, to
                        name a few.

Is there a segment of   We think the prospects for financial services remains
the market you're       strong, but as always, we'll continue to emphasize
currently targeting?    individual companies' strengths rather than expectations
                        for industry groups going forward.

What is your outlook    Assuming we continue to have relatively low interest
for the Fund?           rates, we think the market should continue to perform
                        well, though with a more usual level of up and down
                        volatility than we saw in 1995. After this year's
                        market, we believe investors looking for reasonable
                        valuations should return to smaller company value stocks
                        for their appreciation potential. A renewed focus on
                        these stocks would benefit the Fund.

                                                                              43

MassMutual International Equity Fund - Portfolio Manager Report
- --------------------------------------------------------------------------------

What are the investment The objectives and policies of the Fund are to:
objectives and policies 
for the MassMutual      . achieve high total rate of return over the long term
International Equity
Fund?                   . invest in a diversified portfolio of foreign and
                          domestic equity securities

                        . utilize dominant themes to guide investment decisions
                          (economic, political and social influences that are
                          expected to dictate long-term growth trends)

                        Note: foreign investments entail special investment
                        risks including differences in foreign accounting and
                        legal standards, foreign taxation, and fluctuations of
                        currency exchange rates.

How has the Fund        Against an exceptionally strong U.S. market, 
performed over the      international markets as a group--even while some
year?                   outperformed the U.S.--paled by comparison. Though the
                        mature U.S. market is rarely among the world's 
                        top-performing markets, it was in 1995. The S&P 500, a
                        broad measure of domestic stocks, was up 37.58% while
                        the MSCI EAFE, which is an index of foreign market
                        stocks, was up 11.21% for the year. The Fund performed
                        reasonably well within this environment, though its
                        performance tended to lag some of its market indices due
                        to the Fund's heavier weightings in Europe and Latin
                        America, which were poorly performing markets in 1995.

What strategic moves    The Fund remains highly diversified, both by sector and
have you made within    by region. We invest across eight global themes that we
the portfolio?          believe offer long-term opportunity. A company's ability
                        to fit into one of these target areas, plus its
                        fundamental strengths and the strength of its country's
                        economy help us to determine its relative value.

                        In terms of theme, we've added to our capital market
                        holdings over the year, through emerging market banks--
                        in places like South America, Turkey and the Far East,
                        and life insurance and money management companies in
                        Europe. In corporate restructurings, we've added to
                        selected companies that have been shedding assets and
                        returning to profitable core businesses. Our investments
                        in efficiency-enhancing technology which, at 19% of the
                        portfolio, is one of our largest themes, has been 
                        two-pronged. Just over half of our holdings have been in
                        areas considered high tech--software, semiconductor and
                        electronics companies--with the remainder having been in
                        heavier industries, for example machinery that is used
                        to increase industry productivity. As a lower-volatility
                        way to invest in emerging consumer markets, which at 20%
                        is our largest emphasis, we've focused primarily on
                        European-based companies whose earnings growth comes
                        from the emerging markets. In healthcare, which is a
                        global business we feel offers strong growth potential
                        in the long-term, we own selected pharmaceuticals,
                        medical equipment and hospital owning companies. We own
                        electric and gas utilities in Argentina and Korea as
                        well as selected U.K. and Japanese equipment
                        manufacturers as part of our infrastructure theme. In
                        natural resources, we're focused on oil and energy
                        services companies we feel offer potential after a 
                        15-year tightening. And finally, our communications
                        investments have surrounded cellular communications
                        firms with emerging markets exposure as well as media
                        and broadcast companies in a position to increase their
                        market shares either globally or regionally.

What Segments of the    We'd like to continue to maintain a reasonable balance
market are you          between our investment themes, looking for opportunities
currently focusing on?  to buy what we consider the best companies within them
                        without paying too much. Regionally, our move into Japan
                        has been the biggest recent change. Though the Japanese
                        market performed poorly in 1995, we expect growth to
                        improve due to a decline in the value of the yen and the
                        central bank's actions to control deflation. Another
                        area that performed poorly in 1995 that we're currently
                        focusing on is Latin America. There we're adding to our
                        holdings in the higher-quality markets such as Brazil,
                        Argentina and Peru.

What is your outlook    Our outlook is strongly positive. Companies in
for the Fund?           international markets, with economic growth rates often
                        two-to-three times the rate of growth in the U.S., have
                        tremendous opportunities to grow earnings, which is what
                        drives the stock markets. And though foreign investing
                        entails special risks including differences in
                        accounting and legal standards, foreign taxation and
                        currency exchange rate fluctuations, we believe it also
                        offers opportunities for diversification and growth
                        potential that are not available within the U.S.

                                                                              51

1. The Trust            MassMutual Institutional Funds (the "Trust") is
                        registered under the Investment Company Act of 1940, as
                        amended (the "1940 Act"), as an open-end, diversified
                        management investment company. The Trust is organized
                        under the laws of the Commonwealth of Massachusetts as a
                        Massachusetts business trust pursuant to an Agreement
                        and Declaration of Trust dated May 28, 1993, as amended.
                        The Trust consists of seven separate series of shares
                        (each individually referred to as a "Fund" or
                        collectively as the "Funds"), each having four classes
                        of shares: Class 1, Class 2, Class 3 and Class 4. Class
                        1, Class 2 and Class 3 shares of each Fund are offered
                        primarily to employer-sponsored defined contribution
                        plans that satisfy the qualification requirements of
                        Section 401(a) of the Internal Revenue Code of 1986, as
                        amended (the "Code"). Class 4 shares of each Fund are
                        available only to separate investment accounts ("SIAs")
                        of Massachusetts Mutual Life Insurance Company
                        ("MassMutual") in which corporate qualified plans
                        including defined contribution plans and defined benefit
                        plans are permitted to invest pursuant to the issuance
                        of group annuity contracts. The Funds are MassMutual
                        Prime Fund ("Prime Fund"), MassMutual Short-Term Bond
                        Fund ("Short-Term Bond Fund"), MassMutual Core Bond Fund
                        ("Core Bond Fund"), MassMutual Balanced Fund ("Balanced
                        Fund"), MassMutual Value Equity Fund ("Value Equity
                        Fund"), MassMutual Small Cap Value Equity Fund ("Small
                        Cap Value Equity Fund"), and MassMutual International
                        Equity Fund ("International Equity Fund").

                        The Trust commenced operations on October 3, 1994, prior
                        to which its only activity was the receipt of a $107,000
                        investment from MassMutual and a $2,848,337,441 transfer
                        of Class 4 shares of the Funds in exchange for the
                        assets of certain MassMutual separate accounts and the
                        assumption of any liabilities attributable to those
                        assets. Accordingly, beginning net assets as of October
                        3, 1994 (commencement of operations) reflect these
                        amounts. This exchange was nontaxable, whereby the
                        carryover basis and holding period of the assets
                        exchanged was the same immediately after the exchange.

                        On November 2, 1994 MassMutual invested an additional
                        $1,995,000 in Classes 1, 2 and 3 of the Funds.

2. Significant          The following is a summary of significant accounting
   Accounting           policies followed consistently by each Fund in the
   Policies             preparation of the financial statements in conformity
                        with generally accepted accounting principles. The
                        preparation of the 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.

         Investment     Equity securities are valued on the basis of valuations
          Valuation     furnished by a pricing service, authorized by the Board
                        of Trustees, which provides the last reported sale price
                        for securities listed on a national securities exchange
                        or on the NASDAQ national market system, or in the case
                        of over-the-counter securities not so listed, the last
                        reported bid price. Debt securities (other than short-
                        term obligations with a remaining maturity of sixty days
                        or less) are valued on the basis of valuations furnished
                        by a pricing service, authorized by the Board of
                        Trustees, which determines valuations taking into
                        account appropriate factors such as institutional-size
                        trading in similar groups of securities, yield, quality,
                        coupon rate, maturity, type of issue, trading
                        characteristics and other market data. Money market
                        obligations with a remaining maturity of sixty days or
                        less are valued at either amortized cost or at original
                        cost plus accrued interest, whichever approximates
                        current market value. All other securities and other
                        assets, including debt securities for which the prices
                        supplied by a pricing agent are deemed by MassMutual not
                        to be representative of market values, and including
                        restricted securities and securities for which no market
                        quotation is available, are valued at fair value in
                        accordance with procedures approved by and determined in
                        good faith by the Trustees although the actual
                        calculation may be done by others.

                        Portfolio securities traded on more than one United
                        States ("U.S.") national securities exchange or foreign
                        securities exchange are valued at the last price on the
                        business day as of which such value is being determined
                        at the close of the exchange representing the principal
                        market for such securities. All assets and liabilities
                        expressed in foreign currencies will be converted into
                        U.S. dollars at the mean between the buying and selling
                        rates of such currencies against U.S. dollars last
                        quoted by any major bank. If such quotations are not
                        available, the rate of exchange will be determined in
                        accordance with policies established by the Trustees.

                                                                              59

Notes to Financial Statements (Continued)

     Accounting for     Investment transactions are accounted for on the trade
        Investments     date. Realized gains and losses on sales of investments
                        and unrealized appreciation and depreciation of
                        investments are computed on the specific identification
                        cost method. Interest income, adjusted for amortization
                        of discounts and premiums on investments, is earned from
                        the settlement date and is recorded on the accrual
                        basis. Dividend income is recorded on the ex-dividend
                        date.

 Federal Income Tax     It is each Fund's intent to comply with the provisions
                        of subchapter M of the Code applicable to a regulated
                        investment company. Under such provisions, the Funds
                        will not be subject to federal income taxes on their
                        ordinary income and net realized capital gain to the
                        extent they are distributed or deemed to have been
                        distributed to their shareholders. Therefore, no Federal
                        income tax provision is required.

      Dividends and     Dividends from net investment income and distributions
   Distributions to     of any net realized capital gains of each Fund are
       Shareholders     declared and paid annually and at other times as may be
                        required to satisfy tax or regulatory requirements.
                        Distributions to shareholders are recorded on the ex-
                        dividend date. Income and capital gain distributions are
                        determined in accordance with income tax regulations
                        which may differ from generally accepted accounting
                        principles. These differences are primarily due to
                        investments in forward contracts, passive foreign
                        investment companies, the deferral of wash sale losses,
                        and paydowns on certain mortgage-backed securities. As a
                        result, net investment income (loss) and net realized
                        gain (loss) on investment transactions for a reporting
                        period may differ significantly from distributions
                        during such period. Accordingly, the Funds may
                        periodically make reclassifications among certain of
                        their capital accounts without impacting the net asset
                        value of the Funds.

   Foreign Currency     The books and records of the Funds are maintained in
        Translation     U.S. dollars. The market values of foreign currencies,
                        foreign securities and other assets and liabilities
                        denominated in foreign currencies are translated into
                        U.S. dollars at the mean of the buying and selling rates
                        of such currencies against the U.S. dollar at the end of
                        each business day. Purchases and sales of foreign
                        securities and income and expense items are translated
                        at the rates of exchange prevailing on the respective
                        dates of such transactions. The Funds do not isolate
                        that portion of the results of operations arising from
                        changes in the exchange rates from that portion arising
                        from changes in the market prices of securities.

                        Net realized foreign currency gains and losses resulting
                        from changes in exchange rates include foreign currency
                        gains and losses between trade date and settlement date
                        on investment securities transactions, foreign currency
                        transactions and the difference between the amounts of
                        dividends recorded on the books of the Funds and the
                        amount actually received.

    Forward Foreign     Each Fund may enter into forward foreign currency
 Currency Contracts     contracts in order to convert foreign denominated
                        securities or obligations to U.S. dollar denominated
                        investments. The International Equity Fund may engage in
                        such transactions to manage the value of portfolio
                        holdings against future movements in certain foreign
                        currency exchange rates. A forward foreign currency
                        contract is an agreement between two parties to buy and
                        sell a currency at a set price on a future date. The
                        market value of a forward currency contract fluctuates
                        with changes in forward foreign currency exchange rates.
                        Forward foreign currency contracts are marked to market
                        daily and the change in their value is recorded by the
                        Funds as an unrealized gain or loss. When a forward
                        foreign currency contract is extinguished, through
                        delivery or offset by entering into another forward
                        foreign currency contract, the Funds record a realized
                        gain or loss equal to the difference between the value
                        of the contract at the time it was opened and the value
                        of the contract at the time it was extinguished or
                        offset.

                        Forward foreign currency contracts involve a risk of
                        loss from the potential inability of counterparties to
                        meet the terms of their contracts and from unanticipated
                        movements in foreign currency values and interest rates.

                        The notional or contractual amounts of these instruments
                        represent the investments the Funds have in particular
                        classes of financial instruments and do not necessarily

</TABLE>

            Forward     Each Fund may purchase or sell securities on a "when
        Commitments     issued" or delayed delivery or on a forward commitment
                        basis. The Funds use forward commitments to manage
                        interest rate exposure or as a temporary substitute for
                        purchasing or selling particular debt securities.
                        Forward commitments are not used for purposes of
                        trading. Delivery and payment for securities purchased
                        on a forward commitment basis can take place a month or
                        more after the date of the transaction. The Funds
                        instruct the custodian to segregate assets in a separate
                        account with a current market value at least equal to
                        the amount of its forward purchase commitments. The
                        price of the underlying security and the date when the
                        securities will be delivered and paid for are fixed at
                        the time the transaction is negotiated. The value of the
                        forward commitment is determined by management using a
                        commonly accepted pricing model and fluctuates based
                        upon changes in the value of the underlying security and
                        market repurchase rates. Such rates equate the
                        counterparty's cost to purchase and finance the
                        underlying security to the earnings received on the
                        security and forward delivery proceeds. The Funds record
                        on a daily basis the unrealized
                        appreciation/depreciation based upon changes in the
                        value of the forward commitment. When a forward
                        commitment contract is closed, the Funds record a
                        realized gain or loss equal to the difference between
                        the value of the contract at the time it was opened and
                        the value of the contract at the time it was
                        extinguished. Forward commitments involve a risk of loss
                        if the value of the security to be purchased declines
                        prior to the settlement date. The Funds could also be
                        exposed to loss if they cannot close out their forward
                        commitments because of an illiquid secondary market, or
                        the inability of counterparties to perform. The Funds
                        monitor exposure to ensure counterparties are
                        creditworthy and concentration of exposure is minimized.
                        A summary of open obligations under these forward
                        commitments at December 31, 1995, is as follows:

      Allocation of     In maintaining the records for the Funds, the income and
 Operating Activity     expense accounts are allocated to each class of shares.
                        Investment income, unrealized and realized gains or
                        losses are prorated among the classes of shares based on
                        the relative net assets of each. Expenses are allocated
                        to each class of shares depending on the nature of the
                        expenditures. Administration and distribution and
                        service fees, which are directly attributable to a class
                        of shares, are charged to that class' operations.
                        Expenses of the Fund not directly attributable to the
                        operations of any class of shares or Fund are prorated
                        among the Funds and classes to which the expense relates
                        based on the relative net assets of each. Total expenses
                        per class are currently limited to a percentage of
                        average daily net assets, as discussed in Note 3.

                        Asset Management Corporation ("HarbourView"). These
                        agreements provide that (1) Concert Capital will manage
                        the investment and reinvestment of the assets of the

                        HarbourView will manage the investment and reinvestment
                        of the assets of the International Equity Fund.

                        MassMutual pays Concert Capital a fee equal to an annual
                        rate of .13% of the average daily net asset value of the
                        Value Equity Fund and the Value Equity sector of the
                        Balanced Fund and .25% of the average daily net asset
                        value of the Small Cap Value Equity Fund. MassMutual
                        pays HarbourView a fee equal to an annual rate of .50%
                        of the average daily net asset value of the
                        International Equity Fund.

Administration Fees     Under separate administrative and shareholder services
                        agreements between each Fund and MassMutual, MassMutual
                        provides certain administrative and shareholder services
                        and bears some class specific administrative expenses.
                        In return for these services, MassMutual receives an
                        administrative services fee monthly based upon the
                        average daily net assets of the applicable class of

   Distribution and     Oppenheimer Funds Distributor, Inc. ("Oppenheimer") acts
       Service Fees     as distributor to each Fund. MML Investor Services, Inc.
                        ("MMLISI") serves as sub-distributor to each Fund.
                        Oppenheimer and MMLISI are subsidiaries of MassMutual.
                        Oppenheimer is paid a distribution fee with respect to
                        Class 1 and Class 2 at the annual rate of .40% and .15%,
                        respectively, of the value of average daily net assets
                        attributable to those classes of shares of which a
                        portion is subsequently allocated to MMLISI. The Funds
                        do not pay any fees directly to MMLISI. MassMutual is
                        also paid a fee for shareholder services with respect to
                        Class 1 shares of the Funds at the annual rate of .25%
                        of the value of the average daily net assets of the
                        respective class of each Fund. These fees are authorized
                        pursuant to separate service and distribution plans for
                        each of the classes of shares adopted by the Funds
                        pursuant to Rule 12b-1 under the Investment Company Act
                        and are used by Oppenheimer to cover expenses primarily
                        intended to result in the sale of those shares of the
                        Funds.

Expense Limitations     MassMutual has voluntarily agreed to waive a portion of
                        its management fee to the extent that the aggregate

6. Foreign              The International Equity Fund invests substantially all
   Securities           of its assets in foreign securities. The other Funds may
                        also invest in foreign securities, subject to certain
                        percentage restrictions. Investing in securities of
                        foreign companies and foreign governments involves
                        special risks and considerations not typically
                        associated with investing in securities of U.S.
                        companies and the U.S. Government. These risks include
                        revaluation of currencies and future adverse political
                        and economic developments. Moreover, securities of many
                        foreign companies and foreign governments and their
                        markets may be less liquid and their prices more
                        volatile than those of securities of comparable U.S.
                        companies and the U.S. Government.

7. Federal Income       At December 31, 1995, the cost of securities and the
   Tax Information      unrealized appreciation (depreciation) in the value of
                        investments owned by the Funds, as computed on a Federal

                        To the Board of Trustees and Shareholders of the
                        MassMutual Institutional Funds:

                        We have audited the accompanying statements of assets
                        and liabilities of the MassMutual Institutional Funds,
                        comprising, respectively, the Prime, Short-Term Bond,
                        Core Bond, Balanced, Value Equity, Small Cap Value
                        Equity and International Equity Funds, (the "Funds"),
                        including the portfolios of investments, as of December
                        31, 1995, and the related statements of operations for
                        the year then ended and changes in net assets and
                        financial highlights for the year ended December 31,
                        1995 and for the period from October 3, 1994
                        (commencement of operations) through December 31, 1994.
                        These financial statements and financial highlights are
                        the responsibility of the Funds' management. Our
                        responsibility is to express an opinion on these
                        financial statements and financial highlights based on
                        our audits.

                        We conducted our audits in accordance with generally
                        accepted auditing standards. Those standards require
                        that we plan and perform the audit to obtain reasonable
                        assurance about whether the financial statements and
                        financial highlights are free of material misstatement.
                        An audit includes examining, on a test basis, evidence
                        supporting the amounts and disclosures in the financial
                        statements. Our procedures included confirmation of
                        securities owned as of December 31, 1995, by
                        correspondence with the custodian and brokers. An audit
                        also includes assessing the accounting principles used
                        and significant estimates made by management, as well as
                        evaluating the overall financial statement presentation.
                        We believe that our audits provide a reasonable basis
                        for our opinion.

                        In our opinion, the financial statements and financial
                        highlights referred to above present fairly, in all
                        material respects, the financial position of each of the
                        respective funds constituting the MassMutual
                        Institutional Funds as of December 31, 1994, the results
                        of their operations for the year then ended and the
                        changes in their net assets and their financial
                        highlights for the year ended December 31,1995 and for
                        the period from October 3, 1994 (commencement of
                        operations) through December 31, 1994, in conformity
                        with generally accepted accounting principles.
