PART III — NARRATIVE

State below in reasonable detail why Forms 10-K, 20-F, 11-K, 10-Q, 10-D, N-SAR, N-CSR, or the transition report or portion thereof, could not be filed within the prescribed time period.

The Federal Home Loan Bank of Boston (the Bank) is unable to file its Annual Report on Form 10-K for the year ended December 31, 2008, to be filed pursuant to the Securities Exchange Act of 1934, by March 31, 2009, the original due date, as the Bank has not been able to complete its assessment for other-than-temporary-impairment (OTTI) of certain of its private-label mortgage-backed securities (MBS) and consequently has been unable to finalize its audited financial statements. We have recently obtained information relevant to the Bank’s OTTI assessment of certain of its private-label MBS subsequent to the completion of the Bank’s initial analysis which must be evaluated prior to finalizing our OTTI assessment. Accordingly, the assessment could not be completed by March 31, 2009 without unreasonable effort or expense.

PART IV — OTHER INFORMATION

(1)	Name and telephone number of person to contact in regard to this notification
	Frank Nitkiewicz	(617)	292-9600
	(Name)	(Area Code)	(Telephone Number)

(2)	Have all other periodic reports required under Section 13 or 15(d) of the Securities Exchange Act of 1934 or Section 30 of the Investment Company Act of 1940 during the preceding 12 months or for such shorter period that the registrant was required to file such report(s) been filed? If answer is no, identify report(s).

			x Yes o No

(3)	Is it anticipated that any significant change in results of operations from the corresponding period for the last fiscal year will be reflected by the earnings statements to be included in the subject report or portion thereof?

			x Yes o No

	If so, attach an explanation of the anticipated change, both narratively and quantitatively, and, if appropriate, state the reasons why a reasonable estimate of the results cannot be made. Due to the ongoing OTTI assessment described in Part III of this Form 12b-25 above, the Bank has not finalized its financial statements for the year ended December 31, 2008. However, as announced in the Bank’s February 26, 2009 press release (the Press Release), which was included as an exhibit to the Bank’s Current Report on Form 8-K filed on February 26, 2009, the Bank expects to report significant changes in results of operations for the year ended December 31, 2008 as compared to the prior fiscal year, including an annual net loss primarily attributable to charges related to the OTTI of certain private-label mortgage-backed securities (MBS) as of December 31, 2008 compared with net income of $198.2 million for the year ended December 31, 2007. As announced in the Press Release, the annual net loss based on the Bank’s unaudited results at the time of the Press Release was $73.2 million, primarily attributable to a $339.1 million charge related to the OTTI of certain MBS as of December 31, 2008. It is possible that the Bank will determine that it will have additional charges arising from its OTTI assessment of certain of its MBS for the Bank’s audited results and any such charges would further reduce the Bank’s net income for the year ended December 31, 2008. A reasonable estimate of any such additional charges cannot be made until the ongoing assessment described above is finalized. Forward-Looking Statements This notification includes forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995, based on the Bank’s expectations as of the date of this notification. In some cases, the words “will”, “it is possible”, “estimate” and similar expressions are used in this notification to identify such forward-looking statements. The Bank cautions that, by their nature, forward-looking statements involve risks and uncertainties, including, but not limited to, instability in the credit, debt and housing markets, economic conditions (including effects on, among other things, mortgage-backed securities), changes in interest rates, and prepayment spreads on mortgage assets, and the Bank can provide no assurance that such forward-looking statements will be realized. Other risks are identified in the Bank’s periodic reports filed pursuant to the Securities Exchange Act of 1934, including the Bank’s Annual Report on Form 10-K for the fiscal year ended December 31, 2007 and Quarterly Reports on Form 10-Q for the periods ended September 30, 2008, June 30, 2008 and March 31, 2008. The Bank does not undertake to update any forward-looking statement herein or that may be made from time to time on behalf of the Bank.
