                       A Letter From The President   3
- --------------------------------------------------------------------------------

Dear Client:

1998 marked an unprecedented fourth straight year of returns greater than 20% 
as measured by the S&P 500/R/ Index.

The final year-end numbers though, mask the high drama investors experienced 
during the course of the year.  The S&P 500/R/ Index had one of its most 
volatile years, rising over 20% through June, plummeting 19% during the next two
months, and rallying to record the strongest fourth quarter return since 1926. 
Even while the S&P 500/R/ Index increased 28.6% for the year, it was driven by a
narrow group of stocks. Fifteen stocks represented half of the gain of the 
entire index, while the average stock in the S&P 500/R/ increased only 13.9%. 
Stocks of smaller companies fared even worse, declining 2.6% as measured by the 
Russell 2000 Index.

Overseas markets struggled with their own issues. The European community 
prepared to introduce a common currency on January 1, 1999. Russia devalued the 
ruble causing a broad decline in many emerging markets, and Japan continued to 
struggle with a stubborn recession.

The bond market offered few places to hide. Russia's devaluation spurred fixed 
income investors to sell otherwise solid credits and fly to the safety of U.S. 
Treasuries. It was only after the Federal Reserve lowered interest rates three 
times that investors began buying again and both the U.S. stock and bond markets
rallied.

Some investors wonder why they needed "professional" advise in 1998 when they 
could have bought an index fund or a few internet stocks. We feel very strongly 
that times change, fads change and ultimately investment returns are driven by 
company and industry fundamentals. Our investment managers employ disciplined 
investment strategies that have been proven over time. They structure their 
portfolios to capture today's opportunities while worrying about tomorrow's 
potential decline.

Our manager of managers program is structured to provide formal oversight of 
each manager's organization and investment performance. This structure is costly
but we believe it provides a higher level of service to our clients. Results 
have been strong and we are proud to report that almost three-quarters of our 
investment managers outperformed their peer groups during both 1998 and the 
trailing three-year period as measured by Lipper, Inc.

In addition, we continue to look for ways to improve our investment program. In 
February, we introduced two new funds to broaden your investment options: Select
Emerging Markets Fund and Select Strategic Growth Fund. In February, the board 
voted to hire T. Rowe Price Associates as the new sub-adviser for the Select 
Capital Appreciation Fund. For more information on these and all of the funds, 
we urge you to read the market overviews and managers' commentaries found later 
in this report.

Once again, we urge you to work closely with your financial advisor to build a 
diversified portfolio, not only to succeed in good times, but to protect the 
value of your assets in bad times.

On behalf of the Board of Trustees,

/s/ John F. O'Brien

              Domestic & International Equity Market Overview   6
- --------------------------------------------------------------------------------

1994: 
Federal Reserve Board raises interest rates six times, stalling equity
markets even while corporate earnings continued to grow. 

1995: 
Favorable economic conditions result in large gains for the U.S. equity markets.
Europe turns in strongest performance of international equity markets.

1996: 
Despite a volatile marketplace, the U.S. stock market performs well.
Internationally, European countries post the most impressive gains.

1997: 
Robust economic growth, declining interest rates and low unemployment produce a
third consecutive year of unprecedented gains for the U.S. stock market.

1998: 
Worldwide economic problems cause considerable volatility for stocks. Yet, the
market posts its fourth consecutive year of double-digit gains.

1998 proved to be one of the most volatile years for the stock market since the
crash of 1987. Widely expected by many investors to be a cooling off period for
stocks, the past year brought a series of ups and downs -- and double-digit 
gains -- to the market. In fact, it proved to be the fourth straight year of 
plus- 20% returns for the S&P 500/R/ Index.

The roller coaster ride for stocks began mid-year as economic turmoil in
Asia, Russia and Latin America resulted in increased investor concern. This
turmoil produced a third quarter of market extremes. In July, the market posted
an all-time high. But August brought a severe correction as investors feared
lower worldwide demand for goods and services would lead to slower earnings
growth for U.S. corporations. 

But slower earnings growth proved not to deter investors altogether. While they
fled investments exposed to international market risk, they favored the safety
and predictability of large-company U.S. stocks -- regardless of how vastly
overpriced they seemed.

Once the Federal Reserve cut interest rates for the third time in November,
investors returned to the market in full force. They poured money into a small
group of large-company stocks, sending broad market indexes soaring to another
year of strong performance. In fact, S&P 500/R/ performance was dominated
throughout the year by only a few high-powered names such as Microsoft Corp.,
Dell Computer Corp., Intel Corp.

While large-cap gains outpaced both small- and mid-cap stocks and drove overall
market performance, technology led sector performance for the year. Internet-
related stocks, in particular, drove results even higher. Specifically,
companies such as Amazon.com, an on-line book seller and eBay.com, an on-line
auction service, saw their market values explode. Although these Internet stocks
are not included in the S&P 500/R/ Index, they helped bolster the entire
technology sector. Investors seemed to feel that any company involved in
computers would benefit from an Internet-driven surge in demand.

              Domestic & International Equity Market Overview   7
- --------------------------------------------------------------------------------

Other top-performing industry groups in 1998 were telecommunications which
benefited from merger and acquisition activity, and retailers, which fared well
as a result of strong consumer spending. On the other hand, market laggards were
dominated by oil services, which felt the painful effects of sharply declining
crude oil prices.

On the international front, Europe performed well in 1998, encouraged by
the anticipated monetary union. In fact, Greece's stock market, led all global
performers with a smashing 86% return. Countries such as Italy and Belgium also
performed particularly well in this region. 

However, results from emerging market countries weren't as rosy. Currency
concerns plagued Asia for much of 1998. While Japan's stock market went through
a series of ups and downs, countries like Thailand and Korea started taking
serious measures to turn their economies around -- and it definitely made a
difference. South Korea proved to be one of the top-performing countries during
1998.

Russia, however, wasn't so favored. By mid-year, massive economic problems and a
large devaluation in the ruble caused investors to flee Russian stocks and
bonds, sending shock waves throughout the world's financial markets.

As a result of Russia's economic collapse, investors grew more concerned about
what the impact would be on other emerging markets. These worries particularly
affected Brazil, which unlike Russia, managed to keep currency devaluation at
bay thanks to support from the U.S., promises of reform and higher interest
rates. Unfortunately, the higher cost of borrowing stunted economic growth and
sent Brazil's economy into a recession.

Economic problems weren't confined to just Brazil, however. Slumping
prices for crude oil and other commodities curbed economic growth in other parts
of Latin America as well. Because oil prices make up about 70% of the
government's revenue, Venezuela was particularly hard hit. Political concerns
also were a factor here and combined to produce one of the worst-performing
markets for the year. 

Currently, uncertainty exists throughout the world's stock markets. In the U.S.,
stable interest rates and low inflation bode well for the stock market, but
slower corporate earnings growth continues to be a concern. In Europe, the
introduction of the Euro, the new single currency for Europe, should benefit the
region. However, slower earnings growth remains a concern. And although Japan
and most of Asia appear to be on the road to economic recovery, great
uncertainty still exists in these markets.

Given the unsettled nature of the global economy, it will be difficult for the
U.S. stock market to continue its four-year string of outstanding returns.

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


With a total return of 10.56% for the one-year period ended December 31, 1998,
the Select Aggressive Growth Fund outpaced the 0.38% return of the Russell 2500
Index for the same period. 

Although large-cap stocks drove market performance overall, both small- and 
mid-cap holdings performed well for the Fund in 1998.

Several reasons accounted for the Fund's favorable results. First, superior
stock selection in the technology, consumer services and retail trade sectors
boosted performance. Not only did Fund holdings such as Dell Computer Corp., EMC
Corp., and Best Buy, Inc. all deliver triple-digit returns, but the sharp price
appreciation in internet-related stocks, such as Yahoo, Inc. also enhanced
returns. 

During the past year, the Fund's managers also held fewer investments
relative to the benchmark in out-of-favor market sectors. While the Russell 2500
Index held an average weighting of 18% and 14% in financial services and
producer/manufacturing, respectively, the Fund's managers chose to hold an
average weighting of just 5% and 9% in these sectors. As a result, the Fund
garnered additional results. 

Entering 1999, the Fund's managers have a positive outlook on many sectors,
including commercial/industrial, consumer durables, consumer non-durables,
health care services, retail trade and technology.

Despite concerns about deflation and earnings growth, the managers are
optimistic about the small- and mid-cap markets. They also caution that given
the slowdown in worldwide growth, investors should anticipate more moderate
returns in the future.

The Select Aggressive Growth Fund is a portfolio of the Allmerica Investment
Trust.

Portfolio composition will vary over time.

Past performance is no guarantee of future results. Investment return and
principal value of an investment will fluctuate so that an investor's shares,
when redeemed, may be worth more or less than their original cost.

The Russell 2500 Index is an unmanaged composite of 2,500 small-to-mid
capitalization stocks. The Lipper Capital Appreciation Funds Average is a non-
weighted average of 280 funds within the capital appreciation investment
objective. Performance numbers are net of all fund operating expenses, but do
not include insurance charges. If performance information included the effect of

For the one-year period ended December 31, 1998, the Select International Equity
Fund returned 16.48% versus the 20.33% return of the Morgan Stanley EAFE Index.

During 1998, the Growth in Telecommunications theme outperformed all other
themes for the Fund. Both the growth in the mobile phone market and the
privatization of Europe's telecommunications companies contributed to its
strength. New partnerships also fueled the market as companies such as
Mannesmann of Germany and Olivetti of Italy teamed up to provide international
phone service.

Holdings in Vodaphone also benefited from announced links with Lucent
Technologies to market wireless technology.

The Healthcare Needs theme also added results. In response to the market
turbulence in the third quarter, investors sought the stable earnings of
pharmaceutical stocks. As a result, holdings such as Glaxo Wellcome and Hoechst
made particularly strong contributions to the portfolio.

British American Tobacco was a top performer in the Leading Consumer Franchise
theme. These shares were bolstered by news of the successful spin-off of Allied
Zurich, its financial services business, and favorable news about U.S.
litigation.

On the downside, stocks in the Infrastructural Development, Tech-nological
Innovation and Expanding Financial Services in Developing Markets themes were
the poorest performers due to their significant exposure to the Far East.

Looking ahead, the Fund's managers plan to concentrate on European stocks that
they believe will prosper in the new single currency environment as well as
selected companies in Japan.

With a total return of 19.32% for the one-year period ended December 31, 1998,
the Growth Fund trailed the 28.58% return of the S&P 500/R/ Index for the same
period.

During the past year, the stock market confounded many experts by acting
contrary to long-held investment principles. It favored mega-sized companies,
overvalued growth stocks, and high-priced consumer staple stocks over
defensively priced cyclicals, and issues with high, instead of low, P/E ratios.

In addition to these factors, sector selection accounted for some missed results
as the Fund was underweighted in retail, one of the strongest performing
sectors, yet overweighted in basic resources and consumer durables, two poorly
performing sectors.

To better position the Fund, the managers gradually shifted the portfolio
balance from more value-oriented stocks to more growth-oriented. This shift was
achieved by steadily reducing positions in economically sensitive sector stocks
and reallocating resources into other sectors.

Financials, utilities and health care were increased. Technology holdings were
also increased to a large sector weighting in the portfolio. As a result, the
portfolio outperformed the S&P 500/R/ Index during the fourth quarter -- the
strongest fourth calendar quarter since 1926.

Looking ahead, the Fund's managers see mixed signals for domestic equities but
believe their broadly diversified portfolio is well-positioned for investors.

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

For the one-year period ended December 31, 1998, the Equity Index Fund reported
a total return of 28.33% essentially matching the 28.58% return of the S&P
500/R/ Index for the same period.

During 1998, the S&P 500/R/ Index enjoyed a stellar year of performance. More
significantly, it posted a greater than 20% return -- for the fourth year in a
row. This was in spite of a volatile third quarter marked by a global financial
crisis, particularly in Russia, and the Long Term Capital debacle which erased
many of the year-to-date gains at the time, temporarily.

Fueled by several credit-easing moves taken by the Federal Reserve later in the
year, the market rebounded. Led by companies associated with the Internet,
particularly E-commerce companies, the market was further catapulted by the
prospect of more shoppers migrating to virtual stores.

In addition, specific company performance added to overall market gains. During
the year, Microsoft and General Electric proved to be the largest contributors
while traditional cyclical stocks such as Dupont and Caterpillar finished 1998
among the market's laggards.

Other companies detracting from results were Schlumberger, an oil field service
company which suffered from declining oil prices, and Citigroup, the result of
this year's merger between Travelers and Citibank.

In keeping with the Fund's investment objective, the managers will continue to
seek to mirror the returns of the S&P 500/R/ Index and adjust the portfolio's
holdings accordingly.

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


1994:  Federal Reserve Board raises interest rates six times in an effort to
       slow down the economy and keep inflation in check, sending bond prices
       sharply lower.

1995:  U.S. bond market enjoys its third best performance in 30 years, thanks to
       strong total returns from 30-year U.S. Treasuries and corporate issues.

1996:  Outlook for Federal Reserve policy affects U.S. bond market. Long-
       predicted interest rate cuts, which would have fueled this market, never
       occur.

1997:  Low inflation and declining interest rates fuel the bond market, which
       enjoys its best returns since 1995.

1998:  During 1998, bond investments produced widely divergent results as a
       series of dramatic swings either left them highly in favor or badly
       battered.

During 1998, bond investments produced widely divergent results as they
experienced a series of dramatic swings that left them either highly in favor or
badly battered.

Starting off 1998, investors sought more attractive yields by investing in all
types of riskier bonds. But as global markets experienced continued volatility
 -- most notably in Russia, Latin America and Asia -- investors fled these
riskier investments and, by late summer, favored U.S. Treasury bonds.

But what was a boon for Treasuries was not at all good for non-government
issues. The Russian currency crisis, President Clinton's problems, and concerns
about Japan's economy all caused non-government issues to deteriorate by August.
Further aggravated by the collapse of the highly leveraged Long-Term Capital
Management, this segment, particularly corporate and high-yield bonds, suffered.
Because investors stayed away from these types of securities, the corporate new
issues market dried up. In fact, fewer investment grade and high-yield bonds
were sold in August and September combined than in the month of July.

However, a year-end rally was sparked by a series of three 0.25% interest rate
cuts by the Federal Reserve. These moves not only pushed the Federal Funds Rates
down to 4.75%, they spurred bond investors to leave the safety of U.S.
Treasuries and return to those securities which had the potential to offer them
higher yields.

Given this environment, safer credits generally fared much better for the year
than those bonds which had more risk attached to them.

Finishing the year on top, U.S. Treasuries significantly outpaced all other
sectors of the bond market for the first time in almost a decade -- with the 
30-year bond posting a total return of 17.10% for the year. By comparison, the

Brothers Aggregate Bond Index, a benchmark commonly used for all types of bonds,
returned only 8.67%.

In contrast, 1998 will also be remembered as the worst year for corporate bonds.
Investment grade corporates trailed comparable duration Treasuries by 2.27% for
the year. Much of the underperformance occurred from late August to mid October
as liquidity, rather than credit, concerns drove the unprecedented spread
widening. However, a two-tiered market still exists for corporate credits.
Benchmark names such as IBM, Ford and Worldcom trade with little or no liquidity
concession, while second-tier names command a much larger liquidity premium.

While it was a year of turmoil for investment grade corporate bonds, it proved
to be disastrous for high-yield corporates, which lagged BBB or higher rated
bonds by nearly five percentage points. Suffering the most from the year's
volatility, lower-rated high-yield issues finished last for 1998 with a meager
3.66% total return, as measured by the Merrill Lynch High Yield Master Index.

Reflecting the market in general, mortgage-backed securities also had a
tumultuous year. Early in the year, this sector struggled with fears of
prepayments as interest rates dipped to historic lows. Even so, these securities
managed to modestly outperform Treasuries for the first half of the year. Then,
the same liquidity concerns that troubled corporate bonds later in the year also
severely affected mortgage-backeds. As a result, this sector posted a total
return of 7.20% for the year.

Results in the money market also mirrored the overall turbulence occurring in
the bond market. While yields hovered around 5.00% before the interest rate cuts
taken by the Federal Reserve, yields on the average one-year CD fell from 4.87%
to 4.16% by year-end.

Diminishing returns, however, did not seem to sway investors. Money funds in
general posted record inflows of cash as investors sought shelter from market
volatility and parked their assets in the relative safety of money market funds.

Moving into 1999, volatility remains on the horizon for the U.S. bond market.
However, given low inflation and low interest rates, government and high-grade
corporates could appeal to investors looking for safe havens from riskier
alternatives. In addition, slower corporate earnings could restrain the stock
market in the coming year, helping to narrow the performance gap between
equities and fixed income investments.

                      Investment Grade Income Fund     14
- --------------------------------------------------------------------------------

For the one-year period ended December 31,1998, the Investment Grade Income Fund
posted a total return of 7.97% compared to the 8.67% return of the Lehman
Brothers Aggregate Bond Index for the same period.

1998 proved to be a disappointing year for both corporate bond and mortgage-
backed securities (MBS) performance. Much of the deterioration occurred between
late-August and mid-October as a global financial crisis developed and investors
fled to safety and liquidity in the form of super-safe U.S. Treasuries.

Unfortunately, this Fund had a significant portion of its assets allocated to
the corporate sector -- and to lower-quality credits.

However, two factors mitigated some of the underperformance. The Fund maintained
a heavy weighting in the Media and Telecommunications sector, a top-performing
sector of the Investment Grade corporate bond market for the year. And it also
held such blue-chip names as IBM and Worldcom, which were two investor favorites
throughout the year.

As with the corporate bond market, liquidity concerns caused mortgage-backed
securities to suffer during the second half of the year. The Fund's managers,
however, maintained their position in these securities as Treasury yields
started to rise and the threat of massive prepayments subsided.

Moving into the new year, the Fund's managers expect to retain their current
positions in corporate bonds and mortgage-backed securities and have noted that
trading and pricing in the bond market has returned to more normal levels.

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

For the one-year period ended December 31, 1998, the Government Bond Fund turned
in a 7.67% total return, less than the 8.49% return of the Lehman Intermediate
Government Bond Index for the same period.

During 1998, turmoil in worldwide markets caused investors to retreat from
riskier investments to super-safe U.S. Treasury bonds. As further economic
crises surfaced late in the year, particularly in Latin America and Russia, the
Federal Reserve cut interest rates to ease the possibility of a domestic credit
crunch. Investors then sold off their Treasuries in favor of the higher yields
they could gain from riskier investment alternatives.

In response to these changing market conditions, the Fund's managers adjusted
the Fund's holdings throughout the year. First, they substantially trimmed the
portfolio's exposure to mortgage-backed securities to protect against prepayment
risk. And to take advantage of lower prices, the Fund's managers doubled the
Fund's exposure to agency securities as spreads became increasingly more
attractive. They also reduced holdings in asset backed securities from 12% to
8%, which they plan to add to if spreads grow wider.

Looking ahead, the Fund's managers believe interest rates will remain at or near
current levels. Given this outlook, they feel the Fund is well-positioned for
favorable results.

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


The Money Market Fund reported a 5.51% total return for the one-year period
ended December 31, 1998, outpacing the 4.96% return of the IBC/Donoghue First
Tier Money Market Index for the same period.

During 1998, the U.S. economy showed surprising strength in the face of extreme
volatility in world financial markets. The Asian currency crisis spread to Latin
America and Russia, spurring a worldwide sell-off of riskier assets and forcing
highly leveraged trading firms, like Long Term Capital Management, to liquidate
positions as the value of their holdings fell.

To alleviate a potential credit crunch, the Federal Reserve cut the Federal
Funds rate three separate times, and yields on money market funds plummeted
causing securities prices to rise. This helped the Fund's performance as the
portfolio was well-positioned with longer maturing money market securities
averaging 77 days.

After the Fed's moves, the Fund's managers lowered the Fund's average weighted
maturity to 62 days to better position the Fund to garner returns when interest
rates start back up.

The Fund's managers also maintained core long-term holdings of (5-7 month)
commercial paper and certificates of deposits and kept a combination of floating
rate notes. In addition, they laddered maturity dates and short-term repurchase
agreements to provide maximum liquidity without sacrificing yield.

Entering a new year, the Fund's managers believe the Federal Reserve will
maintain a neutral monetary policy in the near future.

                         NOTES TO FINANCIAL STATEMENTS


1.   Organization

Allmerica Investment Trust (the "Trust") is registered under the Investment
Company Act of 1940 (the "1940 Act"), as amended, as an open-end, diversified
management investment company established as a Massachusetts business trust for
the purpose of providing a vehicle for the investment of assets of various
separate accounts established by Allmerica Financial Life Insurance and Annuity
Company ("Allmerica Financial"), a wholly-owned subsidiary of First Allmerica
Financial Life Insurance Company ("First Allmerica") or other affiliated
insurance companies. As of the date of this report, the Trust offered fourteen
managed investment portfolios. The accompanying financial statements and
financial highlights are those of the Select Aggressive Growth, Select
International Equity, Growth, Equity Index, Investment Grade Income, Government
Bond and Money Market Funds (individually, a "Portfolio," collectively, the
"Portfolios").

2.   Significant Accounting Policies

The preparation of financial statements in conformity with generally accepted
accounting principles requires 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. The following is a summary of significant
accounting policies which are in conformity with generally accepted accounting
principles and consistently followed by the Trust in the preparation of its
financial statements.

Security Valuation: Securities which are traded on a recognized exchange
(including securities traded through the National Market System) are valued at
the last sale price on the securities exchange on which such securities are
primarily traded or, if there were no sales that day, at the mean of the closing
bid and asked price. Over-the-counter securities that are not traded through the
National Market System are valued on the basis of the bid price at the close of
business each day. Short-term investments that mature in 60 days or less are
valued at amortized cost. Corporate debt securities and debt securities of the
U.S. Government and its agencies (other than short-term investments) are valued
by an independent pricing service approved by the Board of Trustees which
utilizes market quotations and transactions, quotations from dealers and various
relationships among securities in determining value. If not valued by a pricing
service, such securities are valued at prices obtained from independent brokers.
Investments with prices that cannot be readily obtained are carried at fair
value as determined in good faith under consistently applied procedures
established by and under the supervision of the Board of Trustees. The
investments of the Money Market Fund are valued utilizing the amortized cost
valuation method permitted in accordance with Rule 2a-7 under the 1940 Act. This
method involves valuing a portfolio security initially at its cost and
thereafter assuming a constant amortization to maturity of any discount or
premium.

Forward Foreign Currency Contracts: The Select International Equity Fund may
enter into forward foreign currency contracts whereby the Portfolio agrees to
exchange a specific currency at a specific price at a future date in an attempt
to hedge against fluctuations in the value of the underlying currency of certain
portfolio instruments. Forward foreign currency contracts are valued at the
daily exchange rate of the underlying currency with any fluctuations recorded as
unrealized gains or losses. Receivables and payables of forward foreign currency
contracts are presented on a net basis in the Statements of Assets and
Liabilities. Gains or losses on the purchase or sale of forward foreign currency
contracts having the same settlement date and broker are recognized on the date
of offset, otherwise gains and losses are recognized on the settlement date.

The use of forward foreign currency contracts does not eliminate fluctuations in
the underlying prices of the Portfolio, but it does establish a rate of exchange
that can be achieved in the future. Although forward foreign currency contracts
used for hedging purposes limit the risk of loss due to a decline in the value
of the hedged currency, they also limit any potential gain that might result
should the value of the currency increase. In addition, the Portfolio could be
exposed to risks if the counterparties to the contracts are unable to meet the
terms of their contracts.

                          Allmerica Investment Trust

                   NOTES TO FINANCIAL STATEMENTS, Continued


Foreign Currency Translation: Investment valuations, other assets and
liabilities denominated in foreign currencies are converted each business day
into U.S. dollars based upon current exchange rates. Purchases and sales of
foreign investments and income and expenses are converted into U.S. dollars
based upon exchange rates prevailing on the respective dates of such
transactions. That portion of unrealized gains or losses on investments due to
fluctuations in foreign currency exchange rates is not separately disclosed.

Security Transactions and Investment Income: Security transactions are recorded
on the trade date. Net realized gains and losses from security transactions are
recorded on the basis of identified cost. Interest income, including
amortization of premium and accretion of discount on securities, is accrued
daily. Dividend income is recorded on the ex-dividend date, except that certain
dividends from foreign securities are recorded as soon as the Portfolios are
informed of the ex-dividend date.

Federal Income Taxes: The Trust treats each Portfolio as a separate entity for
Federal income tax purposes. Each Portfolio intends to qualify as a "regulated
investment company" under Subchapter M of the Internal Revenue Code of 1986, as
amended. By so qualifying, each Portfolio will not be subject to Federal income
taxes to the extent it distributes all of its taxable income and net realized
gains for the tax year ending December 31. In addition, by distributing during
each calendar year substantially all of its net investment income, capital gains
and certain other amounts, if any, each Portfolio will not be subject to Federal
excise tax. Therefore, no Federal income tax provision is required. Withholding
taxes on foreign dividend income and gains have been paid or provided for in
accordance with the applicable country's tax rules and rates.

Distributions to Shareholders: Dividends from net investment income are declared
and reinvested daily for the Money Market Fund, declared and distributed
quarterly for the Growth, Equity Index, Investment Grade Income and Government
Bond Funds, and annually for the Select Aggressive Growth and Select
International Equity Funds. All Portfolios declare and distribute all net
realized capital gains, if any, at least annually. The distributions 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
differing book and tax treatments in the timing of the recognition of gains or
losses and forwards, including "Post-October Losses" and permanent differences
due to differing treatments for paydown gains/losses on certain securities,
foreign currency transactions, market discount, non-taxable dividends and losses
deferred due to wash sales. Any taxable income or gain remaining at fiscal year
end is distributed in the following year.

Paid-in capital, undistributed net investment income and accumulated net
realized gain (loss) have been adjusted in the Statements of Assets and
Liabilities for permanent book-tax differences for all Portfolios for the year
ended December 31, 1998.

Permanent book-tax differences, if any, are not included in ending undistributed
net investment income for the purpose of calculating net investment income per
share in the Financial Highlights.

Futures Contracts: All Portfolios, except the Money Market Fund, may enter into
futures contracts for the delayed delivery of securities at a fixed price at
some future date or the change in value of a specified financial index over a
predetermined time period. Cash or securities are deposited with brokers in
order to establish and maintain a position. Subsequent payments made or received
by the Portfolio based on the daily change in the market value of the position
are recorded as unrealized gain or loss until the contract is closed out, at
which time the gain or loss is realized.

Securities Lending: Each Portfolio, using Bankers Trust Company ("Bankers
Trust") as their agent, may loan securities to brokers who pay the Portfolio
negotiated lenders' fees. These fees are disclosed as "securities lending
income" on the Statements of Operations. Each applicable Portfolio receives
obligations of the U.S. government and its agencies, cash and/or cash
equivalents and/or letters of credit as collateral against the loaned
securities, in an amount at least equal to 102% of the market value of the
loaned securities at the inception of each loan. This collateral must be
maintained at not less than 102% of the market value of the loaned securities
during the period of the loan. Information regarding the value of the securities
loaned and the value of collateral at period end is included under the caption
"Other Information" at the end of each applicable Portfolio's schedule of
investments.

                                                                           F-35

                          Allmerica Investment Trust

                   NOTES TO FINANCIAL STATEMENTS, Continued

Each Portfolio pays Bankers Trust fees for its services from the
securities lending program. For the year ended December 31, 1998, the Select
Aggressive Growth Fund and Select International Equity Fund paid Bankers Trust
$99,827 and $35,923, respectively.

Expenses: The Trust accounts separately for assets, liabilities and operations
of each Portfolio. Expenses directly attributed to a Portfolio are charged to
the Portfolio, while expenses which are attributable to more than one Portfolio
of the Trust are allocated among the respective Portfolios.

Forward Commitments: The Investment Grade Income Fund, Government Bond Fund and
Money Market Fund may enter into contracts to purchase securities for a fixed
price at a specified future date beyond customary settlement time ("forward
commitments"). If the Portfolios do so, they will maintain cash or other liquid
obligations having a value in an amount at all times sufficient to meet the
purchase price. Forward commitments involve a risk of loss if the value of the
security to be purchased declines prior to the settlement date. Although the
Portfolios generally will enter into forward commitments with the intention of
acquiring the securities for their portfolio, they may dispose of a commitment
prior to settlement if their Sub-Adviser deems it appropriate to do so.

Repurchase Agreements: Each Portfolio may engage in repurchase agreement
transactions with institutions that the Sub-Adviser has determined are
creditworthy pursuant to guidelines established by the Trust's Board of
Trustees. Each repurchase agreement transaction is recorded at cost. Each
Portfolio requires that the securities purchased in a repurchase agreement
transaction be transferred to the Trust's Custodian in a manner that is intended
to enable the Portfolio to obtain those securities in the event of a
counterparty default. The Investment Adviser monitors the value of the
securities, including accrued interest, daily to ensure that the value of the
collateral equals or exceeds amounts due under the repurchase agreement.
Repurchase agreement transactions involve certain risks in the event of default
or insolvency of the counterparty, including possible delays or restrictions
upon the Portfolio's ability to dispose of the underlying securities, and a
possible decline in the value of the underlying securities during the period
while the Portfolio seeks to assert its rights.

3.   INVESTMENT ADVISORY, ADMINISTRATION 
     AND OTHER RELATED PARTY TRANSACTIONS

Allmerica Financial Investment Management Services, Inc. (the "Manager"), a
wholly-owned subsidiary of First Allmerica, serves as Investment Adviser and
Administrator to the Trust. The Manager succeeded Allmerica Investment
Management Company, Inc. as manager of the Trust on April 16, 1998. Under the
terms of the management agreement, the Portfolios pay a management fee,
calculated daily and payable monthly, at an annual rate based upon the following
fee schedules:

                Percentage of Average Daily Net Assets

The Manager has entered into Sub-Adviser Agreements for the management of the
investments of each of the Portfolios. The Manager is solely responsible for the
payment of all fees to the Sub-Advisers. The Sub-Advisers for each of the
Portfolios are as follows:

Select Aggressive Growth        Nicholas-Applegate Capital Management, L.P.
Select International Equity     Bank of Ireland Asset Management (U.S.) Limited
Growth                          Miller Anderson & Sherrerd, LLP
Equity Index                    Allmerica Asset Management, Inc.
Investment Grade Income         Allmerica Asset Management, Inc.
Government Bond                 Allmerica Asset Management, Inc.
Money Market                    Allmerica Asset Management, Inc.

Miller Anderson & Sherrerd, LLP also manages certain assets for First Allmerica
and its affiliates.

The Manager has entered into an Administrative Services Agreement with First
Data Investor Services Group, Inc. ("Investor Services Group"), a wholly-owned
subsidiary of First Data Corporation, whereby Investor Services Group performs
certain administrative services for the Portfolios and is entitled to receive an
administrative fee and certain out-of-pocket expenses. The Manager is solely
responsible for the payment of the administration fee to Investor Services
Group. In a separate agreement, Investor Services Group receives separate fees
from the Portfolios for certain fund accounting services provided in its
capacity as pricing and bookkeeping agent.

The Trust pays no salaries or compensation to any of its officers. Trustees who
are not directors, officers, or employees of the Trust or any investment adviser
are reimbursed for their travel expenses in attending meetings of the Trustees,
and receive quarterly meeting and retainer fees for their services. Such amounts
are paid by the Trust.

4.   REIMBURSEMENT OF EXPENSES AND WAIVER OF FEES

In the event normal operating expenses of each Portfolio, excluding taxes,
interest, broker commissions and extraordinary expenses, but including the
advisory fee, exceed certain voluntary expense limitations by a percentage of
average net assets (Select Aggressive Growth Fund - 1.35%, Select International
Equity Fund - 1.50%, Growth Fund - 1.20%, Equity Index Fund - 0.60%, Investment
Grade Income Fund - 1.00%, Government Bond Fund - 1.00% and Money Market Fund -
0.60%), the Manager will voluntarily reimburse fees and any expenses in excess
of the expense limitations. Expense limitations may be removed or revised at any
time after a Portfolio's first fiscal year of operations without prior notice to
existing shareholders.

5.   REDUCTION OF EXPENSES

Certain Portfolios have entered into agreements with brokers whereby the brokers
will rebate a portion of brokerage commissions. Such amounts earned by the
Portfolios, under such agreements, are presented as a reduction of expenses in
the Statements of Operations.

                                                                           F-37

                   NOTES TO FINANCIAL STATEMENTS, Continued

6.   SHARES OF BENEFICIAL INTEREST

The Trust's Declaration of Trust authorizes the Trustees to issue an unlimited
number of shares of beneficial interest for the Portfolios, each without a par
value. During the year ended December 31, 1998, First Allmerica redeemed
5,231,487 shares of Select International Equity, and 6,353,213 shares of Equity
Index.

7.   FOREIGN SECURITIES AND EMERGING MARKETS

All Portfolios, except the Government Bond Fund, may purchase securities of
foreign issuers. The Money Market Fund may invest in only U.S. dollar
denominated foreign securities. Investing in foreign securities involves special
risks not typically associated with investing in securities of U.S. issuers. The
risks include revaluation of currencies and future adverse political and
economic developments. Moreover, securities of many foreign issuers and their
markets may be less liquid and their prices more volatile than those of
securities of comparable U.S. issuers.

Investing in emerging markets may involve special risks and considerations not
typically associated with investing in the developed markets. These risks
include revaluation of currencies, high rates of inflation, repatriation
restrictions on income and capital, and future adverse political and economic
developments. Moreover, securities issued in these markets may be less liquid,
subject to government ownership controls, subject to delayed settlements, and
their prices more volatile than those of comparable securities in the United
States.

8.   FINANCIAL INSTRUMENTS

Investing in certain financial instruments including futures and options
transactions, and forward foreign currency contracts involves risk other than
that reflected in the Statements of Assets and Liabilities. Risks associated
with these instruments include the potential for an imperfect correlation
between the movements in the price of the instruments and the price of the
underlying securities and interest rates, an illiquid secondary market for the
instruments or inability of counterparties to perform under the terms of the
contracts, and changes in the value of foreign currency relative to the U.S.
dollar. The Select International Equity Fund may enter into these forward
contracts primarily to protect the Portfolio from adverse currency movement.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Trustees and Shareholders
of Allmerica Investment Trust

In our opinion, the accompanying statements of assets and liabilities, including
the portfolios of investments (except for Moody's and S&P Ratings), and the
related statements of operations and of changes in net assets and the financial
highlights present fairly, in all material respects, the financial position of
the Select Aggressive Growth Fund, Select International Equity Fund, Growth
Fund, Equity Index Fund, Investment Grade Income Fund, Government Bond Fund and
Money Market Fund, (seven of the funds constituting the Allmerica Investment
Trust, hereafter referred to as the "Trust") at December 31, 1998, the results
of each of their operations, the changes in each of their net assets, and the
financial highlights for the periods indicated, in conformity with generally
accepted accounting principles. These financial statements and financial
highlights (hereafter referred to as "financial statements") are the
responsibility of the Trust's management; our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these financial statements in accordance with generally accepted
auditing standards which require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits, which included confirmation of investments at December 31, 1998 by
correspondence with the custodian and brokers and the application of alternative
auditing procedures where confirmations from brokers were not received, provide
a reasonable basis for the opinion expressed above.

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

Year 2000 (unaudited): Some computer software cannot distinguish between dates
in the year 2000 and dates in the year 1900 because of the way that dates are
encoded and calculated. The services provided to the Trust by the Manager, Sub-
Advisers, Custodian and other external service providers depend on the proper
functioning of their computer software. Failure to correct or replace any non-
compliant software could adversely affect, among other things, the handling of
securities trades, the payment of interest and dividends, the pricing of the
Trust's securities and of the Trust's shares, and account services. The Trust
has requested information from its service providers with respect to their plans
to be Year 2000 compliant. The Trust has been advised by its service providers
that they either are Year 2000 compliant now or expect to be compliant prior to
December 31, 1999. However, there can be no guarantee that the Trust's
operations will not be adversely affected by non-compliant computer systems of
its service providers or other third parties which interact with such service
providers.
