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 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. * The Lehman Brothers U.S. Credit Index is an unmanaged index of all publicly issued, fixed-rate, non-convertible investment grade corporate debt. ------------------------------------------------------------------------------- MOODY'S QUALITY RATINGS* Percentage of Trust's Total Investments Aaa 9% Aa 21% A 25% Baa 31% Ba 11% Caa 1% Not Rated 2% * Standard & Poor's (S&P) credit ratings are used in the absence of a rating by Moody's. ------------------------------------------------------------------------------- SECURITY DIVERSIFICATION Percentage of Trust's Total Investments Corporate Notes and Bonds 77% U.S. Government and Agency Obligations 2% Asset-Backed and Mortgage-Backed Securities 6% Foreign Bonds 10% Foreign Government Obligations 3% Investment Company 1% Municipal Obligations 1% (U.S. Government Agency Mortgage-Backed Obligations amounted to less than 0.5% of the Trust's total investments.) -------------------------------------------------------------------------------- Shareholder inquiries regarding account information may be directed to: The Bank of New York Shareholder Relations Department - 11E PO Box 11258 Church Street Station New York, New York 10286 1-800-432-8224 [logo] ALLMERICA FINANCIAL(R) THE ALLMERICA FINANCIAL COMPANIES --------------------------------- The Hanover Insurance Company o Citizens Insurance Company of America o Citizens Management Inc.
