Item 2.03. Creation of a Direct Financial Obligation or an Obligation under an Off -Balance Sheet Arrangement of a Registrant.

As previously disclosed, The Hanover Insurance Company (“Hanover Insurance”), a wholly owned subsidiary of the Company, had its application approved for membership with the Federal Home Loan Bank of Boston (“FHLBB”). On September 25, 2009, Hanover Insurance received an advance of $125 million as part of the FHLBB’s collateralized borrowing program. The advance will bear interest at a fixed rate of 5.50% per annum over a twenty-year term. Hanover Insurance has pledged government agency securities with a current fair value of approximately $141.7 million to the FHLBB as collateral for the borrowing. The fair value of the collateral pledged by Hanover Insurance must be maintained at certain specified levels of the borrowed amount, which can vary depending on the type of assets pledged. If the fair value of the collateral declines below these specified levels, Hanover Insurance would be required to pledge additional collateral or repay outstanding borrowings. In connection with the borrowing, Hanover Insurance executed the FHLBB’s standard form of Agreement for Advances, Collateral Pledge and Security Agreement, which governs the terms and conditions of the outstanding borrowings and the pledge of collateral. Hanover Insurance is permitted to voluntarily repay the outstanding borrowings at any time, subject to a prepayment fee. As a requirement of membership in the FHLBB, Hanover Insurance acquired $2.5 million of FHLBB stock, and as a condition to participating in the FHLBB’s collateralized borrowing program it is required to purchase additional shares of FHLBB stock in an amount equal to 4.5% of its outstanding borrowings. The proceeds from the borrowing will be used in an intercompany transaction by Hanover Insurance to acquire AIX Holdings, Inc. and its subsidiaries from the Company.
