To Our Shareholders
More Positive News From The U.S.
As we begin 1998, the U.S. economy appears to be embarking on its eighth
consecutive year of expansion. By almost any measure, 1997 was a solidly good
year. Consumption was up, consumer confidence reached a 28-year high,
unemployment hit a 24-year low, gains were made in personal income and corporate
profits, housing starts and new and existing housing sales were up, and the
Federal budget deficit was reduced to a point where 1998 may even see a small
surplus.
All of this happened against a backdrop of declining price pressures fueling
debate over the relevance of the Phillips Curve, which is the historical model
suggesting that economic growth will eventually breed inflation. Inflation
measured by the Consumer Price Index remained below two percent, down from 1996
levels, and both the Producer Price Index and commodities prices dropped.
Without inflationary pressures, the Federal Reserve, which had raised interest
rates by 25 basis points in March, did not take action again for the remainder
of the year, and interest rates consequently declined.
Against Uncertainty From Overseas
Working counter to the forces supporting the domestic economy over the past year
was the financial breakdown in the Pacific Rim. After years of overinvestment,
weak infrastructure and poor economic policy, high-flying markets including
South Korea, Thailand and Indonesia suffered tremendous losses during the second
half of 1997.
The problems these economies face are deep and far-reaching, and recognition of
this fact has caused turmoil in markets throughout the world. Japan, which has
fiscal problems of its own, is a close trading partner to much of the rest of
Southeast Asia and will be impacted by weakness there. The U.S. has seen effects
of the Asian crisis on a number of levels. The uncertainty created by the Asian
crisis added volatility to an already nervous stock market, precipitating a one
day drop in the Dow Jones Industrial Average of over 500 points in late October.
A flight to quality in the currency markets bolstered the U.S. dollar, making
American exports expensive in overseas markets and potentially increasing the
trade deficit. Domestic firms that rely on sales to Asian markets may see
profits come under pressure as orders decline, and competitive price pressures
from Asian exporters may impact the ability for companies to raise prices on a
global basis.
Strength Overcame Volatility in Stocks
Even though the U.S. stock market increased in volatility, it turned in
impressive results for the year. As of December 31, 1997, the S&P 500 was up
33.37%, the Dow Jones Industrial Average increased 24.93%, the NASDAQ was up
21.63% and the Russell 2000 earned 22.36%.
Because of the uncertainty inherent in a market that's enjoyed such a tremendous
three-year advance, plus the concerns that arose from the Asian markets'
problems, it was large cap growth stocks that benefited most during the year.
These companies, which are well-represented in indices like the S&P 500, were
part of a `flight to quality' that the market experienced over the course of the
year. They are companies that are large enough to endure competitive pressures,
and due to their large capitalization, their stocks are very liquid.
A Profitable Year For Bonds
The bond market also advanced during 1997. After the Federal Reserve's March
tightening, rates began to decline, and bonds rallied as a result. During the
second half of the year, investors moved into bonds as a safe haven from stock
market volatility. Rates declined and the yield curve flattened.
Toward the end of the year, bonds paying higher yields than Treasuries seemed to
offer the best opportunities. For the first time in quite a while, there was
some risk premium available in moving lower in quality.

Strategic Positioning For The Future
We expect the positive economic factors that determined 1997's market to
outweigh Asian concerns as 1998 continues. While the situation in the Far East
is dominating current market psychology, the International Monetary Fund is
assembling both the personnel and the financing necessary to begin restoring
investor confidence and economic stability to the region. If that takes hold,
domestic factors should begin to take precedence again. All things considered,
we expect another year of economic growth, but at less vigorous levels than what
we've seen recently.
In any event, recent volatility reminds us of the need to be paid for taking
risk. In this environment, we believe that research, selectivity and a value
orientation will separate winners from losers in both the stock and bond
markets. MassMutual's strategic focus on identifying value in the markets has
been tested over time. Our managers are experienced and talented, and supported
by a team of in-house researchers and analysts. All told, we should be well
positioned to act on the opportunities the coming year presents.

MML EQUITY FUND
How did the Fund perform over the past year?
The Fund did quite well over the year with a 28.59% return, which surpasses both
the long-term average for stocks* and the results of many other value
managers. However, the Fund lagged the performance of the S&P 500 index, which
had a return of 33.37%, an exceptional gain of over 30% for the second time in
the past three years. The S&P 500 has changed in composition over the past
several years, with a much higher component of technology stocks and large
capitalization growth stocks which strongly influence the performance of the
index. The past year saw strong gains in these groups, causing the index to
exceed the results of most active managers. As a value manager, we consider many
of these favored companies as too expensive, with price-earnings ratios at
substantial premiums to the average stock. Such high valuations represent risk
to investors in the event that the companies fall short of expectations. Our
focus on high quality companies selling at more modest valuations should enable
the Fund to compare well with index returns over the full market cycle.
How did the stock market perform over the course of the year?
The market has been remarkably strong over the past three years - in fact we
haven't had three consecutive years this buoyant in decades. This hospitable
market environment benefited from a continued economic expansion without the
obvious excesses of past cycles, stable to declining interest rates, high labor
productivity, healthy corporate profits, and a clear focus on shareholder value
on the part of corporate boards and management.
On closer inspection, the first quarter of the year was somewhat weak due to an
increase in interest rates. From there, the market came roaring back in the
second quarter and through September. Problems in Asian markets caused a
difficult October, including a sharp one-day selloff that interrupted trading.
The market recovered after October, showed strength in December and finished the
year close to the all-time high. Still, the perception of increased risk and
volatility is now firmly in place.
How did your strategy work during this environment?
Our healthcare holdings were among our best performers for the year.
Bristol-Myers, our largest single holding, doubled the performance of the broad
market for the period. Its excellent product pipeline and aggressive marketing
program are increasingly recognized by investors and suggest a favorable outlook
for the coming year, as well.
While a conservative investment approach like ours can lag more aggressive
styles in a powerful bull market, we held up better than most during the
challenges of the fourth quarter. Some of our best performers during that period
were electric utilities and telephone companies, two groups that did not
participate earlier in the year. Their stable, domestically based earnings and
ample dividends were appealing as the Asian situation unfolded. Pinnacle West,
which serves the Phoenix area, was purchased mid-year, and performed well for
the Fund.
The financial stocks in the portfolio achieved outstanding gains throughout the
year. CoreStates Financial, the leading bank in the Philadelphia area, agreed to
be acquired by First Union, and the Fund's holdings benefited accordingly. Other
large gainers included Bank of New York, Comerica, and Norwest, all of which
showed appreciation of 70% or more.
How are you currently positioning the portfolio?
We think selectivity will be the key to this year's market. In general, we're
looking for companies with stable earnings streams, little or no exposure to
Asia, and little import competition. Market valuation continues to be high, but
low interest rates and declining inflation are encouraging signs. Growth in the
economy and corporate profits are likely to be substantially lower than in
recent years, and we have reduced our expectations accordingly. On the negative
side, this country's competitive position has been weakened by the strong
dollar, and import competition is likely to be fierce. This represents an
unusually challenging period for capital equipment and commodity basic
materials. Our emphasis will be on value added products which can retain their
share of market.
Insurance companies may be particularly well positioned, as declining interest
rates increase the value of their bond holdings. American General, a
well-capitalized insurer with a focused management team, is a recent addition to
the portfolio. Finally, well managed specialty chemical companies such as Air
Products, a producer of industrial gases, and Englehard Corp., whose catalysts
provide solutions to air quality problems, offer opportunity for the Fund.
What is your outlook as we enter 1998?
We expect the coming year's market to be challenging. There is still a fair
amount of risk from the unfolding Asian financial situation, and market
valuation continues to be high. Balancing these negatives is the fact that we
can still find individual stocks offering both high quality and valuations which
suggest sound returns over the long term. As always, we will focus on well
financed companies with competitive advantages that can grow earnings at an
attractive rate in the future. This strategy has generated strong returns with
low volatility in the past and we expect continued success in the future.

MML MONEY MARKET FUND
How did the Fund perform over the past year?
The Fund has enjoyed another good year with a 5.18% return, outperforming Lipper
Money Market Instrument Fund Average of 4.90% and keeping investors' purchasing
power well ahead of inflation. Interest rates were favorable for investors
focused on the shortest part of the fixed income spectrum this year and the Fund
took advantage of the opportunities that were created.
How did your market change over the course of the year?
During the first half of the year, there was some concern in the fixed income
markets that the Federal Reserve would raise interest rates to prevent economic
growth from causing higher inflation. Rates did increase once, by 25 basis
points, after the Federal Reserve's March meeting. In the second half,
anticipation of further tightening dissipated. The Federal Reserve's policy
makers met five times during the second half, but did not change rates at all,
due in part to the fact that the rate of increase in the Consumer Price Index
(inflation) was slowing, and that the Producer Price Index and commodity prices
were actually falling. Another reason the Federal Reserve saw no need for action
was the unraveling of the markets in Southeast Asia, a situation that could
potentially slow the growth of the domestic economy.
Yields on bonds at the long end of maturities fell and prices rose as the year
progressed as investors in search of quality looked to Treasuries. Rates at the
short end where we are focused were already competitive, and remained relatively
stable. We were positioned to do well within this type of environment.
What investment decisions worked best for the Fund during the year?
As a pure money market fund, MML Money market was obligated to invest in Tier 1
securities. A combination of commercial paper and agency discount notes
optimized our performance in this high quality sector of the market. Our
diversified portfolio continued to outperform our competitors in the Lipper
Money Market Instrument Fund universe throughout the year.
Another advantage was the average life of our portfolio, a measure of the
maturities of our holdings. Particularly during the second half of the year,
when uncertainty in the broad markets sent investors searching for alternatives
to stocks, demand at the short end of the fixed income market led to higher
rates on new issuance. Beginning December with an average life slightly below
the IBC/Donohue universe of 55 days, our portfolio took advantage of year-end
rate increases, leaving us longer than our competitors at 61 days by year-end.
What is your current investment strategy?
Our agency holdings will continue to be assessed and replaced with
higher-yielding Tier 1 commercial paper, as opportunities exist. As liquidity
needs are met, the average life will be adjusted to align with the IBC/Donohue
universe.
What is your outlook for the Fund as we move into 1998?
We think the outlook is strong. While we're not anticipating any major changes
in interest rates, in the near term, we continue to watch economic and market
data closely. In the current environment, money market securities are paying
competitive rates, and that should continue as the year progresses. And until
the depth of the Asian markets' difficulties are fully understood and corrective
actions taken, we may benefit from the shift in demand from volatile market
sectors in favor of safer, more predictable investments.
MML BOND FUND
How did the Fund perform over the past year?
The Fund performed very well for the year showing a return of 9.91%, slightly
outpacing its benchmark, the Lehman Brothers Government/Corporate Bond Index,
the Fund's benchmark, which had a return of 9.75 for the year. A major factor
contributing to its performance was the overweighting of spread product, that
is, product that offered incremental yield advantages to Treasuries.
Describe the investment climate over the past year.
The past year was another positive one for the U.S. economy. Continued growth
without a serious threat from inflation caused interest rates to trend downward
as the year progressed, making it a generally positive environment for the bond
market as well.

<PAGE>
During the first half of the year, the Federal Reserve's only policy move - a 25
basis point increase - occurred, creating price volatility, especially in
Treasuries. Volatility proved temporary, however. During the second half, stock
investors reacting to uncertainty from the Asian markets' difficulties moved to
the relative safety of the Treasury bond market and their demand caused bond
prices to rise. Coupled with a rise in short term rates, as central bankers
liquidated their Treasury bill holdings, the yield curve flattened, that is, the
differential between short and long rates narrowed. When Treasuries rallied, the
yield spread between them and other categories of bonds with similar maturities
widened, creating opportunities for the Fund.
What investment decisions benefited the portfolio most as the year progressed?
At year end our holdings of spread classes - including asset backed securities,
agency bonds, mortgage backed securities as well as corporate bonds -
represented over 85% of the Fund's assets.
Corporate bonds performed well during most of 1997 as corporate profitability
improved. In the investment grade sector, BBB rated issues performed the best.
Over half of our corporate holdings were invested in credits rated in the BBB
category. Corporate bond spreads widened out late in the third quarter as the
Asia crisis unfolded. We own one security, Korea Development Bank, which was
directly impacted by the Asian crisis. This issue was purchased prior to the
upheaval and its performance suffered for the remainder of the quarter. At
roughly one-quarter of one percent of the portfolio, however, the bond's impact
was minimal, and we expect it will do better as the International Monetary Fund
works to get Asia back on its feet.
Asset backed securities offered us an interesting opportunity late in the year.
The combination of spread-widening and an increase in supply led to some new
investments in this sector. A new type of asset backed security was introduced
in the fourth quarter. Rate reduction bonds issued by California utilities were
priced at attractive levels relative to similarly structured asset backed credit
card transactions.
How are you currently positioning the portfolio?
Assets under management have grown significantly over the course of the year. As
we invest new cash, we continue to focus on those investment opportunities that
offer us attractive yield advantages over Treasuries. Primarily because of
concerns over the impact weakness in Asia may have on domestic corporations,
corporate bonds are selling at significant yield advantages over Treasuries. We
think corporates continue to offer compelling opportunity, but since
Asia-related concerns are real, careful research into individual bonds is
imperative.
The mortgage holdings of the Fund are either "well-seasoned" pass through
issues, low coupon adjustable rates mortgages, or well-structured collateralized
mortgage obligations. All of these types of mortgage backed obligations should
perform well in 1998 if lower rates spur a refinancing wave.
What is your outlook for the Fund heading into 1998?
1998 marks the eighth year of the current economic expansion, and many of the
factors that have kept the economy positive - such as a 28 year high in consumer
confidence, positive corporate earnings, low interest rates and low unemployment
against a background of low to declining inflation - endure. However, new
concerns have arisen as well. Foremost among these is the Asian crisis, which
has the potential to slow growth here in the U.S. So while we continue to look
upon the market favorably, the potential for changes in economic conditions
exists, making research and close monitoring of credits and market activity
important.
With interest rates likely to remain in a close trading range at least until the
Asian markets improve, we think the outlook for both the Fund and the bond
market is positive. While volatility in the stock market may continue to bolster
bond prices, we expect that most of the returns from fixed income investments
will be driven by income in the coming year. We believe our focus on yield and
our analytical strength, as a firm should be a benefit to the Fund in that
environment.
MML BLEND FUND
How did the Fund perform over the past year?
The Fund performed quite well for the year. We're pleased to report that our
stock-picking strategy allowed us to actively participate in another very
positive 12-month period for the equity market. For the year ended December 31,
1997, our return of 20.89% surpassed both the Lipper Analytical one-year average
for balanced funds of 18.94%, and far exceeded the long-term average for the
broad stock market*. The benefits of our balanced strategy were demonstrated
further as the stock market became volatile toward the end of the year. During
the fourth quarter, which was negative for stocks, the income and price
appreciation we garnered from our fixed income holdings allowed us to continue
to report positive results.

<PAGE>
Within your stock holdings, what types of investments were strongest over the
period?
Within stocks, our healthcare holdings were our best performers for the year.
Bristol-Myers, our largest single holding, doubled the performance of the broad
market for the period. Its excellent product development pipeline and aggressive
marketing program caught investors' attention, and that drove the stock to new
highs.
Insurance companies have also been strong. Since they tend to own significant
bond portfolios, they do well in periods of declining interest rates. American
General is a well-capitalized insurer in a steady growth business with a focused
and capable management and it's been a good holding for us for the year.
In basic industries, well-managed chemical companies benefited the Fund. Two
examples were Air Products, a distributor of industrial gases, and Englehard, a
firm providing technological solutions to air quality issues.
Some of our best performers during the turbulent fourth quarter were electric
utilities and telephone companies, up roughly 10 percent as a group during a
down quarter for the broad market. Pinnacle West, a Phoenix-based electric
utility has been a strong performer for us, as has Tampa-based Teco. We feel
both of these companies offer stable earnings and good dividends at reasonable
valuations.
What was your fixed income strategy, and how did it benefit the Fund?
Over the year, we held roughly equivalent portions of bonds and cash, and both
have served the portfolio well. In bonds, we were focused primarily on AA rated
corporate issues, followed by mortgage-backed securities and Treasuries. Most
classes of bonds have performed well, especially during the second half, when
yields declined on fears about the depth of the Asian financial troubles. Price
appreciation resulted from declining rates and then combined with coupon income
to make bonds an excellent investment this year.
We also strategically increased our holdings of cash and short-term debt
instruments this period because of a relatively flat yield curve. When the yield
curve flattens, the yield advantage investors earn by owning longer maturity,
more interest rate sensitive bonds diminishes. Over the past year, we found we
could earn competitive income from short-maturity investments and reduce risk at
the same time.
How are you currently positioning the portfolio and why?
We're very comfortable with the current sector allocation of the portfolio, so
we're not planning on making any significant changes at this time. At year-end,
the Fund was roughly 61 percent invested in stocks, 19 percent in bonds and 20
percent in cash. The overweighting in stocks has been a plus, and we expect that
to continue for the coming year. Additionally our fixed income holdings should
continue to help temper any volatility from the stock portion by providing an
income cushion. Within each of the portfolio's components, we will continue to
use first-hand analysis and intensive research to identify the stock and bond
investments we believe represent the best opportunities for the Fund.
What is your outlook for the Fund as we move into 1998?
We think this will be another good year. The economy continues to show signs of
strength. Consumer confidence is at 28-year high, corporations continue to be
well-managed and profitable, inflation is in decline from an already low level
and interest rates are low and fairly stable. We believe these facts bode well
for the stock market, though volatility may continue due to a combination of
high valuations and financial instability in the Pacific Rim. On the bond side,
we expect returns to come primarily from income after last year's rally, but for
the market to remain positive. If the Federal Reserve begins to fear an economic
slowdown either as fallout from Asia or as a natural part of the economic cycle,
however, rates could decline further. Should that happen, we'd expect even more
strength in the bond sector. Being invested in both markets has been the key to
our strong long-term performance, and we'd expect that strategy will continue to
serve the Fund well, allowing us to capture competitive returns without
excessive exposure to risk.

MML Series Investment Fund
Notes To Financial Statements
1. HISTORY
MML Series Investment Fund (the "MML Trust") is registered under the Investment
Company Act of 1940 as a no-load, registered open end, management investment
company. MML Equity Fund, MML Money Market Fund, MML Managed Bond Fund and MML
Blend Fund (the "Funds") are four series of shares of the MML Trust. The MML
Trust is organized as a business trust under the laws of the Commonwealth of
Massachusetts pursuant to an Agreement and Declaration of Trust.
The MML Trust was established by Massachusetts Mutual Life Insurance Company
("MassMutual") for the purpose of providing vehicles for the investment of
assets of various separate investment accounts established by MassMutual and by
life insurance companies which are subsidiaries of MassMutual. Shares of the MML
Trust are not offered to the general public.
2. SIGNIFICANT ACCOUNTING POLICIES
The following is a summary of significant accounting policies followed
consistently by each Fund in the preparation of the financial statements in
conformity with generally accepted accounting principles.
A. Investment Valuation
Equity securities are valued on the basis of valuations 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. If securities are unlisted, or there
is no reported sale price, the bid price of the prior trade date will be
used. Long-term bonds 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.
For MML Equity Fund, MML Managed Bond Fund, and MML Blend Fund, short-term
securities with more than sixty days to maturity from the date of purchase
are valued at market and short-term securities having a maturity from the
date of purchase of sixty days or less are valued at amortized cost. MML
Money Market Fund's portfolio securities are valued at amortized cost in
accordance with a rule of the Securities and Exchange Commission pursuant to
which MML Money Market Fund must adhere to certain conditions. It is the
intention of MML Money Market Fund to maintain a per share net asset value of
$1.00.
B. Accounting For Investments
Investment transactions are accounted for on trade date. Dividend income is
recorded on the ex-dividend date. Interest income is recorded on the accrual
basis. Premiums and discounts on short-term securities are amortized in
determining interest income.
The cost basis of long-term bonds is not adjusted for amortization of premium
or accrual of discount since MML Managed Bond Fund and MML Blend Fund do not
generally intend to hold such investments until maturity; however, the MML
Trust has elected to accrue for financial reporting purposes, certain
discounts which are required to be accrued for federal income tax purposes.
Realized gains and losses on investment transactions and unrealized
appreciation and depreciation of investments are reported for financial
statement and federal income tax purposes on the identified cost method.
C. Federal Income Tax
The MML Trust has established a policy for each of the Funds to comply with
the provisions of the Internal Revenue Code applicable to regulated
investment companies. As a result, the Funds will not be subject to federal
income tax on any net investment income and any net capital gains to the
extent they are distributed or are deemed to have been distributed to
shareholders. Distributions are determined in accordance with income tax
regulations which may differ from generally accepted accounting principles.
These differences are primarily due to 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.
Pursuant to section 852 of the Internal Revenue Code, the MML Equity Fund,
MML Managed Bond Fund and MML Blend Fund designated $142,233,936; $71,702 and
$161,997,877; respectively, as capital gain dividends for the year ended
December 31, 1997.

Notes To Financial Statements (Continued)
D. Forward Commitments
Each Fund may purchase or sell securities on a "when 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. The Funds may also use forward
commitments to take delivery of the underlying security rather than closing
out the forward contract. Forward commitments are not used for purposes of
trading. Settlement for securities purchased on a forward commitment basis
can take place a month or more after the date of the transaction. The Fund
generally does not take delivery on these forward commitments, but such
commitments are instead settled with offsetting transactions. When a forward
commitment contract is closed, the Funds record a realized gain or loss.
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 Fund monitors exposure to ensure counterparties are credit
worthy and concentration of exposure is minimized. The Funds instruct the
custodian to segregate liquid high quality 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 repo 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. At December 31, 1997, the Fund did not have any open forward
commitments. At December 31, 1996 the Funds had open forward commitments
totaling $4,981,445 and recognized unrealized depreciation of ($6,345).
E. Estimates
The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
3. CAPITAL LOSS CARRYFORWARD
The accumulated net realized loss on investments for the MML Money Market Fund
results in a capital loss carryforward of $13,540 which is available for federal
income tax purposes to offset future capital gains. Of the total carryforward,
$1,639 expires December 31, 1998, $1,204 expires December 31, 2000, $201 expires
December 31, 2001, $5,364 expires December 31, 2002 and $841 expires December
31, 2003 and $4,291 expires December 31, 2005.
4. INVESTMENT MANAGEMENT FEE
MassMutual provides all investment advisory, management and administrative
services needed by the Funds. For acting as such, MassMutual receives a
quarterly fee from each Fund at the annual rate of .50% of the first
$100,000,000 of the average daily net asset value of each Fund, .45% of the next
$200,000,000, .40% of the next $200,000,000, and .35% of any excess over
$500,000,000.
MassMutual has entered into investment sub-advisory agreements with David L.
Babson and Company, Inc. ("Babson"), a wholly-owned subsidiary of DLB
Acquisition Corporation which is a controlled subsidiary of MassMutual. The
agreements provide that Babson manage the assets of MML Equity Fund and the
assets of the Equity Sector of the MML Blend Fund. MassMutual pays Babson a
quarterly fee equal to an annual rate of .13% of the average daily net asset
value of MML Equity Fund and the Equity Sector of MML Blend Fund.
MassMutual has agreed, at least through April 30, 1998, to bear the expenses of
the Funds to the extent that the aggregate expenses (excluding each Fund's
management fee, interest, taxes, brokerage commissions and extraordinary
expenses) incurred during each Fund's fiscal year exceed .11% of the average
daily net asset value of each Fund for such year. For the period ended December
31, 1997, MassMutual was not required to reimburse the Funds for any expenses.

Report Of Independent Accountants
To the Board of Trustees and Shareholders of
MML Series Investment Fund
We have audited the accompanying statements of assets and liabilities, including
the schedules of investments, of the MML Equity Fund, the MML Money Market Fund,
the MML Managed Bond Fund and the MML Blend Fund which are components of the MML
Series Investment Fund (a Massachusetts business trust), as of December 31,
1997, and the related statements of operations for the year then ended, the
statements of changes in net assets for each of the two years in the period then
ended, and the financial highlights for each of the ten years in the period then
ended. These financial statements and financial highlights are the
responsibility of the Fund's 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, 1997 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 Funds as of December 31, 1997, the results of their respective operations
for the year then ended, the changes in their respective net assets for each of
the two years in the period then ended, and the financial highlights for each of
the ten years in the period then ended, in conformity with generally accepted
accounting principles.
