NOTES TO PORTFOLIO OF INVESTMENTS

SECURITY VALUATION

Corporate debt securities and debt securities of the U.S. Government and its agencies (other than short-term investments) are valued using 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. If prices are not readily available or do not accurately reflect fair value for a security, or if a security’s value has been materially affected by events occurring after the close of the exchange or market on which the security is principally traded, that security may be valued by another method that the Board of Trustees believes accurately reflects fair value. A security’s valuation may differ depending on the method used for determining value. Price movements in futures contracts, market and trading trends, the bid/ask quotes of brokers and off-exchange institutional trading may be reviewed in the course of making a good faith determination of a security’s fair value. Short-term investments that mature in 60 days or less are valued at amortized cost. This method involves valuing a portfolio security initially at its cost and thereafter assuming a constant amortization to maturity of any discount or premium.

At March 31, 2005, one security with a value of $231,018 or 0.3% of net assets was valued by management under the direction of the Board of Trustees.

SECURITIES LENDING

Allmerica Securities Trust (the “Trust”), using Investors Bank & Trust Company (“IBT”) as its lending agent, may loan securities to brokers and dealers in exchange for negotiated lenders’ fees. The Trust receives collateral against the loaned securities which must be maintained at not less than 102% of the market value of the loaned securities during the period of the loan. Collateral received is generally cash, and is invested in short-term investments. Lending portfolio securities involves possible delays in receiving additional collateral or in the recovery of the securities or possible loss of rights in the collateral should the counterparty (borrower) not meet its obligations under the terms of the loan. Information regarding the value of the securities loaned and the value of the collateral at period end is included in a footnote at the end of the Trust’s portfolio of investments.

RESTRICTED SECURITIES

At March 31, 2005, the Trust owned the following restricted security constituting 0.3% of net assets, which may not be publicly sold without registration 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 disposal of restricted securities may involve time-consuming negotiations and expense; a prompt sale at an acceptable price may be difficult. The value of restricted 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 Board of Trustees. Additional information on the restricted security is as follows:
