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

The Federal Home Loan Bank of Boston (the Bank) obtains most of its funds from the sale of debt securities, known as consolidated obligations, in the capital markets. Consolidated obligations, which consist of bonds and discount notes, are by regulation the joint and several obligations of the 12 Federal Home Loan Banks (the FHLBanks). Consolidated obligations are sold to the public through the FHLBanks' Office of Finance using authorized securities dealers.

The FHLBanks are regulated by the Federal Housing Finance Agency (the Finance Agency) and the Finance Agency regulations authorize the Finance Agency to require any FHLBank also to repay all or any portion of the principal of or interest on any or all consolidated obligations for which any other FHLBank is the primary obligor. In other words, the Bank is jointly and severally liable with the other FHLBanks for any and all payments due on all of the consolidated obligations issued by the FHLBanks, regardless of whether the Bank receives all or any portion of the proceeds from any particular issuance. Information regarding historical, current, and future issuances of consolidated obligations by the FHLBanks may be obtained from the Office of Finance (http://www.fhlb-of.com). Further, consolidated obligations are backed only by the financial resources of the FHLBanks and are not guaranteed by the United States government.

Schedule A sets forth all consolidated obligation bonds and discount notes committed to be issued by the FHLBanks, for which the Bank is the primary obligor, on the trade dates indicated, other than discount notes with a maturity of one year or less that are issued in the ordinary course of business. [Schedule A also includes any consolidated obligations with a remaining maturity in excess of one year, if any, for which we have assumed the primary repayment obligation from another FHLBank.]

We may elect to change our method of reporting information on the issuance or assumption of consolidated obligations at any time. In reviewing the information in this Current Report on Form 8-K, please note:

• although certain aggregated issuances of consolidated obligations are material to the Bank, we have not made a judgment as to the materiality of any particular consolidated obligation or obligations;

• Schedule A does not address any interest-rate-exchange agreements (or other derivative instruments) that we may enter into as a result of our asset and liability-management strategies and that may be associated, directly or indirectly, with one or more of the reported consolidated obligations;

• Schedule A will not enable a reader to track changes in the total consolidated obligations outstanding for which we are the primary obligor because Schedule A generally excludes consolidated obligation discount notes with a maturity of one year or less and does not reflect whether the proceeds from the issuance of the reported consolidated obligations will be used to, among other things, replace called or maturing consolidated obligations. We will report the total consolidated obligations outstanding for which we are the primary obligor in our periodic reports filed with the Securities and Exchange Commission; and

• the principal amounts reported on Schedule A represent the principal amount of the reported consolidated obligations at par, which may not correspond to the amounts reported in our financial statements prepared in accordance with generally accepted accounting principles contained in our periodic reports filed with the Securities and Exchange Commission, because the par amount does not account for, among other things, any discounts, premiums, or concessions.
