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

Allmerica Securities Trust returned 3.04% for the first quarter of 2004,
underperforming its benchmark, the Lehman Brothers U.S. Credit Index*, which
returned 3.27%.

Bond market returns were surprisingly strong during the quarter, owing primarily
to the sizable decline in interest rates that occurred following two weak job
reports. The yield on the two-year Treasury note fell by 25 basis points, while
the decline was even greater on five to ten-year notes. Monthly job data came in
decidedly weak in January and February, leading many to speculate that the
Federal Reserve Board would keep interest rates unchanged throughout 2004.
However, the job report for March showed strong payroll growth across a wide
range of industries. This new data has since caused the bond market to reverse
course, meaning yields are back up and prices are down. But, one strong job
report may not be enough to spur the Federal Reserve Board into action. The
Investment Manager believes that the Federal Reserve Board remains concerned
about the substantial slack in the labor and production markets and will not
move rates higher until there is sustained job growth of at least 200,000
positions per month. As a result, the Investment Manager thinks that the
financial markets will continue to place a great deal of attention on the
monthly job data and volatility will be high in the days surrounding these
releases. The Investment Manager believes that a trading range of 3.75% to 4.25%
on ten-year Treasury securities will hold for much of this year.

During the quarter, the Portfolio was negatively impacted by the drop in
interest rates, as the Portfolio duration was about 96% of the benchmark
duration. The corporate sector, which comprises about 91.5% of the Portfolio,
struggled this quarter, posting just 9 basis points of excess return. Terrorism
fears, valuation issues and the weak equity market weighed heavily on the
corporate sector during the first quarter. However, based on the strong
technical and fundamental indicators supporting it, the Investment Manager
continues to favor the sector and intends to continue to clip coupon income from
the Portfolio's holdings. The Portfolio has been built from a bottom-up
perspective and has become more concentrated as our research analysts identified
companies with improving fundamentals. The Portfolio has an overweight position
in energy, including companies such as Valero Energy Corporation. The Investment
Manager believes that

The Investment Manager has an upbeat outlook for the economy. The job situation
appears to be improving, business inventories are low, housing is strong and
exports are up. Most economists are projecting GDP growth in the 4-5% range for
the full year, and evidence thus far suggests that type of growth may be
attainable. Many companies are finally considering adding employees and
expanding capital outlays, as their confidence in the recovery improves.
Meanwhile, inflation remains relatively tame, as labor productivity continues to
be strong and global competition remains intense.
