A Letter from the Chairman
[PHOTO]
Dear Client:
1999 was a rather disappointing year for bond investors as the bond market
experienced its worst performance since 1994 and second worst performance since
1973.
Throughout the year the market struggled with the conflicting forces of solid
economic growth and the fear of rising inflation. The U.S. economy continued to
surprise policy makers as strong consumer demand resulted in strong growth
throughout the year. Internationally, emerging markets rebounded from their lows
of 1998 and helped to create more balanced global growth. Together, these forces
resulted in strong economic growth in the U.S. and prompted the bond market to
focus on the fear of rising inflation. Seeking to restrain both the strong
economy and threat of inflation, the Federal Reserve raised interest rates three
times during the year for a total of 0.75%. Rising interest rates forced bond
prices lower and led to a flat bond market for investors even as the credit
quality of most bonds and companies remained quite strong.
Against this backdrop, the Allmerica Securities Trust produced a total return of
- -1.42% for the year outperforming the Lehman Corporate Bond Index by 0.52%. Fund
performance benefited from an allocation to high yield bonds, as the larger
coupons served to more than offset the decline in bond prices caused by rising
interest rates.
We are pleased to report that on February 15, 2000, the Allmerica Securities
Trust Board of Trustees declared a quarterly dividend of $0.20 per share,
payable on March 31, 2000 to shareholders of record on February 29, 2000. For
the one year period ended December 31, 1999, the Trust paid dividends of $0.84
per share, including a $0.04 per share capital gain distribution, producing a
current yield of 9.53% based on the closing price of $8.813. By comparison, the
yield on the 10 year Treasury note as of December 31, 1999 was 6.44%.
Thank you for your continued interest in the Allmerica Securities Trust. The
Trust's manager continues to keep a watchful eye on macro-economic events and is
comfortable that the portfolio is well positioned to continue to provide you
with the competitive returns you have come to enjoy.
On behalf of the Board of Trustees,
/s/ John F. O'Brien

Bond & Money Market Overview
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.
1999: Inflation concerns and a booming U.S. Economy prompt the Federal Reserve
to hike interest rates. Fixed Income markets close the second half with their
worst-performing year ever with the Lehman Aggregate Bond Index returning
- -0.83%.
On the whole, 1999 was disappointing for fixed-income investors. In fact, it was
the second worse performance year ever for the fixed-income markets, as measured
by the total -0.83%, return of the Lehman Aggregate Bond Index.
A handful of universal themes dominated the markets during the year, namely
successive Federal Reserve interest rate hikes, a steepening yield curve,
volatile corporate bond performance, and rising mortgage rates.
1999 began with investors feeling fairly optimistic about the coming year. The
Federal Reserve had acted in the fall of 1998 to avert a global liquidity
meltdown with three easings that lowered short-term rates to 4.75%. The U.S.
economy seemed to be healthy, with expectations for 1999 GDP in the 3.0% range
and subdued inflation running at about a 2% annual rate.
On the international front, Asia and Latin America continued their recovery from
the problems of 1998. Early in the year, Brazil announced a somewhat unexpected
devaluation of its currency, the real. Global markets braced for a round of
panic selling and other negative ripple effects which never materialized.
Against this backdrop, the first quarter of 1999 progressed with no major
disturbances. Inflation stayed at bay and corporate spread tightening reflected
the positive fundamentals of strong earnings growth.
Beginning in the second quarter, however, the picture began to change. The U.S.
economy grew faster than initially projected and the unemployment rate fell
below 4.2%. Investors began to fear that inflation was imminent. In June, the
Federal Reserve responded by raising the Fed Funds interest rate from 4.75% to
5.00%.
July and August saw spread sectors widen dramatically. Corporate treasurers
pushed corporate and asset-backed bonds into the market hoping

Bond & Money Market Overview
to avert a fourth-quarter liquidity trap, which they believed likely as Y2K
fears would drive buyers from the market. Ironically, these efforts became a
self-fulfilling prophesy as treasurers ended up creating their own
mini-liquidity crisis by all trying to issue bonds simultaneously. By August,
there was a second Fed rate hike from 5.00% to 5.25%.
Despite these first two rate increases, the U.S. economy continued to gather
speed in the third and fourth quarters. The nation's third-quarter GDP, for
instance, came in at 5.7%, well above experts' original predictions. Market
participants once again began to worry about a resurgence of inflation. In
response, the Fed raised short-term interest rates for a third and final time in
November to 5.50%.
Investment grade corporate bonds had a good showing at the end of 1999, but
their overall performance was volatile. All excess returns were attributable to
the first and fourth quarters only.
The high yield market finished 1999 on a positive note after poor performance in
the second and third quarters. The market's return for the year was a modest
2.39%, as measured by the Lehman High Yield Corporate Index. The demand side of
the market shifted significantly in 1999, as mutual fund inflows dropped
dramatically to $1.1 billion, down from $15 billion in 1998. Collateralized bond
obligations, structured transactions involving the purchase of high yield debt,
did offset these lower inflows. The market's estimated 4% default rate was the
highest since 1991.
The past year also saw a steepening yield curve as the 30-year Treasury bond,
which began the year at 5.10% on January 1, and ended at 6.49% on December 31.
The mortgage-backed securities market showed strong excess returns for the year,
owing primarily to positive supply/demand factors, an improved prepay
environment, narrowing swap spreads, and lower interest rate volatility. In
particular, Fannie Mae and Freddie Mac assets grew nearly 30% over 1999.
Looking ahead, it is likely that economic growth and strengthening will continue
into 2000, albeit at a slower rate than that of 1999. All signs point to
probable Fed interest rate increases in the new year, with little inflation on
the horizon.

Allmerica Securities Trust
For the period ended December 31, 1999, the Allmerica Securities Trust returned
- -1.42%, outperforming its benchmark, the Lehman Brothers Corporate Bond Index,
which returned -1.94%.
During the first quarter of 1999, inflation remained in check. The second
quarter featured stronger than expected growth and an unemployment rate below
4.2%. The Federal Reserve responded in June by increasing interest rates. August
brought another rate hike, with a third and final one occurring in November.
The yield curve steepened as the 30 year Treasury bond rose from 5.10% on
January 1, to 6.49% at the close of the year. This increase resulted in the
second worse performance year ever for the fixed income markets, as measured by
the total return of the Lehman Aggregate Bond Index.
Although investment grade corporate bonds finished the year strongly,
performance throughout 1999 was volatile, with the first and last quarters of
the year accounting for all excess return. Yield spreads widened during the
second quarter and peaked in August as merger and acquisition activity and Y2K
fears brought corporate issuers to the market in droves.
Individual credit concerns played a key role in the Fund's performance. The
impact of spread widening on some issues was mitigated by the short duration of
those positions and had little effect on overall performance. Various other
position helped performance as their credit outlooks improved.
As with the investment grade market, the high yield market finished the year
strongly in the fourth quarter, following two quarters of poor performance.
Approximately 30% of the portfolio's corporate holdings consist of high-yield
securities, emphasizing the higher-end, BB-rated segment of the below
investment grade market.

NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------
1. ORGANIZATION
Allmerica Securities Trust (the "Trust") was organized as a Massachusetts busi-
ness trust on June 30, 1986, and is registered under the Investment Company Act
of 1940, as amended, as a diversified, closed-end management investment compa-
ny.
2. SIGNIFICANT ACCOUNTING POLICIES
The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions at
the date of the financial statements. Actual results could differ from those
estimates.
The following is a summary of significant accounting policies which are in con-
formity with generally accepted accounting principles consistently followed by
the Trust in the preparation of its financial statements:
Security Valuation: 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 rela-
tionships among securities in determining value. If not valued by a pricing
service, such securities are valued at prices obtained from independent bro-
kers. 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. Short-term
investments that mature in 60 days or less are valued at amortized cost.
Security Transactions and Investment Income: Security transactions are recorded
as of trade date. Realized gains and losses from security transactions are
determined on the basis of identified cost. Interest income, including amorti-
zation of premium and accretion of discount on securities, is accrued daily.
Dividend income is recorded on the ex-dividend date.
Federal Taxes: The Trust intends to continue to qualify as a "regulated invest-
ment company" under Subchapter M of the Internal Revenue Code of 1986, as
amended. By so qualifying, the Trust will not be subject to Federal income
taxes to the extent that it distributes all of its taxable income and net real-
ized gains, if any, for its tax year ending December 31, 1999. In addition, by
distributing during each calendar year substantially all of its net investment
income, capital gains and certain other amounts, if any, the Trust will not be
subject to Federal excise tax. Therefore, no Federal income tax provision is
required.
Distributions to Shareholders: Dividends to shareholders resulting from net
investment income are recorded on the ex-dividend date and paid quarterly. Net
realized capital gains, if any, are distributed at least annually. Income and
capital gains distributions are determined in accordance with income tax regu-
lations which may differ from generally accepted accounting principles. These
differences are primarily due to differing book and tax treatments in the tim-
ing of the recognition of gains or losses, including "Post-October Losses" and
losses deferred due to wash sales; and permanent differences due to differing
treatments for paydown gains/losses on certain securities, foreign currency
transactions, market discount, and non-taxable dividends. Any taxable income or
gain remaining at fiscal year end is distributed in the following year. Perma-
nent book and tax basis differences relating to shareholder distributions will
result in reclassifications to paid in capital. Undistributed net investment
income may include temporary book and tax basis differences which will reverse
in a subsequent period. Permanent book-tax differences, if any, are not
included in ending undistributed net investment income for the purposes of cal-
culating net investment income per share in the Financial Highlights.
Securities Lending: The Trust is using Investors Bank & Trust Company ("Invest-
ors Bank & Trust") as its lending agent to loan securities to brokers in
exchange for negotiated lenders' fees. These fees are included in interest
income on the Statement of Operations. The Trust 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. 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 the collateral at the period end is
included under the caption "Other Information" at the end of the Trust's Port-
folio of Investments. Prior to April 1, 1999 Bankers Trust Company ("Bankers
Trust") was its lending agent.
Expenses: Most expenses of the Trust can be directly attributable to the Trust.
Expenses which cannot be directly attributable to the Trust, are allocated
based upon relative net assets among the Trust and one other affiliated regis-
tered investment company, Allmerica Investment Trust.

3. INVESTMENT ADVISORY FEES AND OTHER RELATED PARTY TRANSACTIONS.
Allmerica Asset Management, Inc. ("AAM"), a direct, wholly-owned subsidiary of
Allmerica Financial Corporation ("Allmerica Financial"), serves as Investment
Adviser to the Trust. For these services, the Trust pays AAM aggregate monthly
compensation at the annual rate of (a) 3/10 of 1% of average net assets plus
(b) 2 1/2% of the amount of interest and dividend income.
To the extent that normal operating expenses of the Trust, excluding taxes,
interest, brokerage commissions and extraordinary expenses, but including the
investment advisory fee, exceed 1.50% of the first $30,000,000 of the Trust's
average weekly net assets, and 1.00% of any excess of such value over
$30,000,000, AAM will bear such excess expenses.
Effective April 1, 1999, AAM and the Trust have entered into a new Administra-
tion Services Agreement and the Trust has entered into a Custodian Agreement
with Investors Bank & Trust, whereby Investors Bank & Trust performs fund
administration, custodian and fund accounting services for the Trust. Investors
Bank & Trust is entitled to receive a fee for these services, in addition to
certain out-of-pocket expenses. AAM is solely responsible for the payment of
the administration fee and the Trust will pay the fees for the fund accounting
and custodian services to Investors Bank & Trust. Prior to April 1, 1999, First
Data Investor Services Group, Inc. performed fund administration and fund
accounting services for the Trust, and custodian services were performed by
Bankers Trust.
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 fees for their services. Such amounts are paid by the Trust.
4. SHARES OF BENEFICIAL INTEREST
There are 10,000,000 shares of $1.00 par value common stock authorized. At
December 31, 1999, First Allmerica Financial Life Insurance Company, a direct,
wholly-owned subsidiary of Allmerica Financial, the Trustees and the officers
of the Trust owned in the aggregate 109,152 shares of beneficial interest.
5. RESTRICTED SECURITIES
At December 31, 1999, the Trust owned the following restricted securities con-
stituting 2.44% of net assets, which may not be publicly sold without registra-
tion under the Securities Act of 1933. The Trust would bear the registration
costs in connection with the disposition of restricted securities held in the
portfolio. The Trust does not have the right to demand that such securities be
registered. The value of these securities is determined by valuations supplied
by a pricing service or brokers or, if not available, in good faith by or at
the direction of the Trustees. Additional information on the restricted securi-
ties is as follows:

REPORT OF INDEPENDENT ACCOUNTANTS
- --------------------------------------------------------------------------------
To the Board of Trustees and Shareholders of Allmerica Securities Trust
In our opinion, the accompanying statement of assets and liabilities, including
the portfolio 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
Allmerica Securities Trust, (hereafter referred to as the "Trust") at December
31, 1999, the results of its operations, the changes in its net assets, and the
financial highlights for the periods indicated, in conformity with accounting
principles generally accepted in the United States. 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 auditing standards gen-
erally accepted in the United States, 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 state-
ments, 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, 1999 by correspondence with the custodian and brokers, provide a reasonable
basis for the opinion expressed above.

REGULATORY DISCLOSURES (Unaudited)
- --------------------------------------------------------------------------------
The performance data quoted represents past performance and the investment
return and principal value of an investment will fluctuate so that an invest-
or's shares, when sold, may be worth more or less than their original cost.
This report is authorized for distribution to existing shareholders of
Allmerica Securities Trust.
SHAREHOLDER TAX INFORMATION
- --------------------------------------------------------------------------------
Distributions from long-term capital gains for the year ended December 31, 1999
were $343,692.
The portion of the Trust dividends that was derived from U.S. Government obli-
gations in 1999 and may be exempt from state income taxation is 17.61%. The
states of California, Connecticut, New York, and New Jersey have exclusionary
provisions, however; each of these states has a threshold requirement that must
be met before the exclusion applies. During 1999, the level of exempt income
did not meet these thresholds and the exclusion does not apply. All other
states and the District of Columbia do not tax dividends attributable to U.S.
Government obligations within the Trust.
Certain states also require, for intangible tax reporting purposes, the report-
ing of the percentage of assets invested in either state specific or state spe-
cific and federal obligations. The percentage applicable to the states of Flor-
ida, Kansas, and Kentucky is 12.34%. The percentage applicable to the State of
West Virginia is 0%.
SHAREHOLDER INFORMATION
- --------------------------------------------------------------------------------
Automatic Dividend Investment Plan: As a shareholder, you may participate in
the Trust's Automatic Dividend Investment Plan. Under the plan, dividends and
other distributions are automatically invested in additional full and frac-
tional shares of the Trust to be held on deposit in your account. Such divi-
dends and other distributions are invested at the net asset value if lower than
market price plus brokerage commission or, if higher, at the market price plus
brokerage commission. You will receive a statement after each payment date for
a dividend or other distribution that will show the details of the transaction
and the status of your account. You may terminate or rejoin at any time.
Cash Investment Plan: The cash investment plan provides a systematic, conve-
nient and inexpensive means to increase your investment in the Trust by putting
your cash to work. The plan permits you to invest amounts ranging from $25 to
$1,000 in any one month to purchase additional shares of the Trust. Regular
monthly investment is not required.
Your funds are consolidated with funds of other participants to purchase
shares. Shares are purchased in bulk and you realize the commission savings.
You pay only a service charge of $1.00 per transaction and your proportionate
share of the brokerage commission.
Your account will be credited with full and fractional shares purchased. Fol-
lowing each investment, you will receive a statement showing the details of the
transaction and the current status of the account. The plan is voluntary and
you may terminate at any time.
