NOTES TO FINANCIAL STATEMENTS

(unaudited)

Note 1 — Basis of Presentation

The accompanying unaudited financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) for interim financial information. Accordingly, they do not include all of the information and footnotes required by GAAP for complete annual financial statements. In the opinion of management, all adjustments considered necessary have been included. All such adjustments consist of normal recurring accruals. The presentation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. The results of operations for interim periods are not necessarily indicative of the results to be expected for the year ending December 31, 2011. The unaudited financial statements should be read in conjunction with the Federal Home Loan Bank of Boston's (the Bank's) audited financial statements and related notes in the Bank's Annual Report on Form 10-K for the year ended December 31, 2010, filed with the Securities and Exchange Commission (the SEC) on March 18, 2011 (the 2010 Annual Report).

Note 2 — Recently Issued Accounting Standards and Interpretations

Disclosures about an Employer’s Participation in a Multiemployer Plan. On September 21, 2011, the Financial Accounting Standards Board (the FASB) issued guidance intended to enhance disclosures about an employer's participation in a multiemployer pension plan. These disclosures are intended to provide users with the following: (1) additional administrative information about an employer's participation in significant multiemployer plans; (2) an employer's participation level in these plans, including contributions made and whether contributions exceed five percent of total contributions made to a plan; (3) the financial health of these plans, including information about funded status and funding improvement plans, as applicable; and (4) the nature of employer commitments to the plan, including expiration dates of collective bargaining agreements and whether such agreements require minimum plan contributions. Previously, disclosures were limited primarily to the historical contributions made to all multiemployer pension plans. The new disclosures are required for annual periods ending December 31, 2011, and will be applied retrospectively for all prior periods presented. The adoption of this amended guidance is likely to result in increased annual financial statement disclosures, but will not affect the Bank's financial condition, results of operations, or cash flows.

Presentation of Comprehensive Income. On June 16, 2011, the FASB issued guidance to increase the prominence of other comprehensive income in financial statements. This guidance requires an entity that reports items of other comprehensive income to present comprehensive income in either a single financial statement or in two consecutive financial statements. In a single continuous statement, an entity is required to present the components of net income and total net income, the components of other comprehensive income, and a total for other comprehensive income, as well as a total for comprehensive income. In a two-statement approach, an entity is required to present the components of net income and total net income in its statement of net income. The statement of other comprehensive income should follow immediately and include the components of other comprehensive income as well as totals for both other comprehensive income and comprehensive income. This guidance eliminates the option to present other comprehensive income in the statement of changes in stockholders' equity. This guidance is effective for the Bank for interim and annual periods beginning on January 1, 2012, and will be applied retrospectively for all periods presented. Early adoption is permitted. The Bank plans to elect the two-statement approach noted above beginning on January 1, 2012. The adoption of this guidance is expected to be limited to the presentation of its annual and interim financial statements and not affect the Bank's financial condition, results of operations, and cash flows.

On October 21, 2011, the FASB voted to propose a deferral of the new requirement to present reclassifications of other comprehensive income in the income statement. Entities would still be required to adopt the other guidance contained in the new accounting standard for the presentation of comprehensive income.

Common Fair Value Measurement and Disclosure Requirements in GAAP and International Financial Reporting Standards (IFRS). On May 12, 2011, the FASB and the International Accounting Standards Board both issued new guidance that results in a consistent definition of fair value and common requirements for measurement of and disclosures about fair value between GAAP and IFRS. While many of the amendments to GAAP are not expected to have a significant effect on practice, the new guidance changes some fair value measurement principles and disclosure requirements currently in GAAP. The new guidance goes into effect on January 1, 2012, for the Bank and will be applied prospectively. The Bank is currently evaluating the effect of the adoption of this guidance on the Bank's financial condition, results of operations, and cash flows.

Reconsideration of Effective Control for Repurchase Agreements. On April 29, 2011, the FASB issued guidance to improve the accounting for repurchase agreements and other agreements that both entitle and obligate a transferor to repurchase or redeem financial assets before their maturity. This guidance amends the existing criteria for determining whether or not a transferor has retained effective control over financial assets transferred under a repurchase agreement. A secured borrowing is recorded when effective control over the transferred financial assets is maintained while a sale is recorded when effective control over the transferred financial assets has not been maintained. The new guidance removes from the assessment of effective control: (1) the criterion requiring the transferor to have the ability to repurchase or redeem financial assets before their maturity on substantially the agreed terms, even in the event of the transferee's default, and (2) the collateral maintenance implementation guidance related to that criterion. This guidance is effective for the Bank's interim and annual periods beginning on January 1, 2012. This guidance will be applied prospectively to transactions or modifications of existing transactions that occur on or after the effective date. Early adoption is not permitted. The adoption of this guidance is not expected to have a material effect on the Bank's financial condition, results of operations, or cash flows.

A Creditor’s Determination of Whether a Restructuring is a Troubled Debt Restructuring. On April 5, 2011, the FASB issued guidance to clarify which debt modifications constitute troubled debt restructurings. It is intended to help creditors determine whether a modification of the terms of a receivable meets the criteria to be considered a troubled debt restructuring, both for purposes of recording an impairment loss and for presenting previously deferred disclosures related to troubled debt restructurings. This guidance is effective for interim and annual periods beginning on or after June 15, 2011 (July 1, 2011, for the Bank), and applies retrospectively to troubled debt restructurings occurring on or after the beginning of the annual period of adoption. The adoption of this amended guidance did not have a material effect on the Bank's financial condition, results of operations, or cash flows.

Disclosures about the Credit Quality of Financing Receivables and the Allowance for Credit Losses. On July 21, 2010, the FASB issued amended guidance to enhance disclosures about an entity's allowance for credit losses and the credit quality of its financing receivables. The required disclosures as of the end of a reporting period became effective for interim and annual reporting periods ending on December 31, 2010. The required disclosures about activity that occurs during a reporting period became effective for interim and annual reporting periods beginning on January 1, 2011. The adoption of this amended guidance resulted in increased annual and interim financial statement disclosures, but did not affect the Bank's financial condition, results of operations, or cash flows.

On January 19, 2011, the FASB issued guidance to temporarily defer the effective date of disclosures about troubled debt restructurings required by the amended guidance on disclosures about the credit quality of financing receivables and the allowance for credit losses. The effective date for these new disclosures was coordinated with the effective date of the guidance for determining what constitutes a troubled debt restructuring.

_______________________

(1)Carrying value of held-to-maturity securities represents the sum of amortized cost and the amount of noncredit-related other-than-temporary impairment recognized in accumulated other comprehensive loss.

(2) MBS are not presented by contractual maturity because their expected maturities will likely differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment fees.

As of September 30, 2011, the amortized cost of the Bank's held-to-maturity securities includes net discounts of $542.5 million. Of that amount, net premiums of $4.0 million relate to non-MBS and net discounts of $546.5 million relate to MBS. As of December 31, 2010, the amortized cost of the Bank's held-to-maturity securities includes net discounts of $523.4 million. Of that amount, net premiums of $5.3 million relate to non-MBS and net discounts of $528.7 million relate to MBS.

Note 6 — Other-Than-Temporary Impairment

The Bank evaluates its individual available-for-sale and held-to-maturity securities for other-than-temporary impairment on a quarterly basis. As part of its evaluation of securities for other-than-temporary impairment, the Bank considers its intent to sell each debt security or whether it is more likely than not that the Bank will be required to sell the security before the anticipated recovery of the remaining amortized cost. If either of these conditions is met, the Bank recognizes an other-than-temporary impairment charge in earnings equal to the entire difference between the security's amortized cost basis and its fair value at the balance-sheet date. For securities that meet neither of these conditions and for all residential private-label MBS, the Bank performs additional analysis to determine if any of these securities are other-than-temporarily impaired.

Available-for-Sale Securities

As a result of these evaluations, the Bank determined that none of its available-for-sale securities were other-than-temporarily impaired at September 30, 2011. The Bank's available-for-sale securities portfolio has experienced unrealized losses that reflect the impact of normal yield and spread fluctuations attendant with security markets. However, the declines are considered

15

temporary as the Bank expects to recover the entire amortized cost basis on these available-for-sale securities in an unrealized loss position and neither intends to sell these securities nor is it more likely than not that the Bank will be required to sell these securities before the anticipated recovery of each security's remaining amortized cost basis. Regarding securities that were in an unrealized loss position as of September 30, 2011:

• Debentures issued by a supranational bank that were in an unrealized loss position as of September 30, 2011, are expected to return contractual principal and interest, based on the Bank's review and analysis of independent third-party credit reports on the supranational entity, and such supranational entity is rated triple-A by each of the nationally recognized statistical rating organizations (NRSROs).

• Debentures issued by U.S. government corporations are not obligations of the U.S. government and not guaranteed by the U.S. government. However, these securities are rated at the same level as the U.S. government by the NRSROs. These ratings reflect the U.S. government's implicit support of the government corporation as well as the entity's underlying business and financial risk.

• The Bank has concluded that the probability of default on debt issued by the Federal National Mortgage Association (Fannie Mae) and the Federal Home Loan Mortgage Corporation (Freddie Mac) is remote given their status as GSEs and their support from the U.S. government. Further, MBS issued by Fannie Mae and Freddie Mac, which we sometimes refer to as agency MBS in this report, are backed by mortgage loans conforming with those GSEs' underwriting requirements and the GSEs' credit guarantees as to full return of principal and interest.

Held-to-Maturity Securities

State or Local Housing-Finance-Agency Obligations. Management has reviewed the state and local housing-finance-agency (HFA) obligations and has determined that unrealized losses reflect the impact of normal market yield and spread fluctuations and illiquidity in the credit markets. The Bank has determined that all unrealized losses are temporary given the creditworthiness of the issuers and the underlying collateral, including an assessment of past payment history, property vacancy rates, debt service ratios, overcollateralization, and third-party bond insurance as applicable. As of September 30, 2011, none of the Bank's held-to-maturity investments in HFA obligations were rated below investment grade by an NRSRO. Because the decline in market value is attributable to changes in interest rates and credit spreads and illiquidity in the credit markets and not to a significant deterioration in the fundamental credit quality of these obligations, and because the Bank does not intend to sell the investments nor is it more likely than not that the Bank will be required to sell the investments before recovery of the amortized cost basis, the Bank does not consider these investments to be other-than-temporarily impaired at September 30, 2011.

Agency MBS. For agency MBS, the Bank determined that the strength of the issuers' guarantees through direct obligation or support from the U.S. government is sufficient to protect the Bank from losses based on current expectations. As a result, the Bank has determined that, as of September 30, 2011, all of the gross unrealized losses on such MBS are temporary. The Bank does not believe that the declines in market value of these securities are attributable to credit quality, and because the Bank does not intend to sell the investments, nor is it more likely than not that the Bank will be required to sell the investments before recovery of the amortized cost basis, the Bank does not consider any of these investments to be other-than-temporarily impaired at September 30, 2011.

Private-Label Residential MBS and ABS Backed by Home Equity Loans. The Bank invested in private-label residential MBS, which as of the date of purchase were all rated triple-A. Each private-label residential MBS may contain one or more forms of credit protection/enhancements, including, but not limited to, guarantee of principal and interest, subordination, over-collateralization and excess interest, and third-party bond insurance.

To ensure consistency in determination of the other-than-temporary impairment for private-label residential MBS and certain home equity loan investments (including home equity ABS) among all Federal Home Loan Banks (the FHLBanks or the FHLBank System), the FHLBanks enhanced their overall other-than-temporary impairment process in 2009 by implementing a Systemwide governance committee (the OTTI Governance Committee) and establishing a formal process to ensure consistency in key other-than-temporary impairment modeling assumptions used for purposes of their cash-flow analyses for the majority of these securities. The Bank uses the FHLBanks' common framework and approved assumptions for purposes of its other-than-temporary impairment cash-flow analysis on its private-label residential MBS and certain home equity loan investments. For certain private-label residential MBS and home equity loan investments where underlying collateral data is not available, the Bank has used alternative procedures to assess these securities for other-than-temporary impairment. The Bank is responsible for making its own determination of impairment and the reasonableness of assumptions, inputs, and methodologies used and for performing the required present value calculations using appropriate historical cost bases and yields.

16

The Bank's evaluation includes estimating the projected cash flows that the Bank is likely to collect based on an assessment of all available information, including the structure of the applicable security and certain assumptions to determine whether the Bank will recover the entire amortized cost basis of the security, such as:

• the remaining payment terms for the security;

• prepayment speeds;

• default rates;

• loss severity on the collateral supporting each security based on underlying loan-level borrower and loan characteristics;

• expected housing price changes; and

• interest-rate assumptions.

In performing a detailed cash-flow analysis, the Bank identifies the best estimate of the cash flows expected to be collected. If this estimate results in a present value of expected cash flows (discounted at the security's effective yield) that is less than the amortized cost basis of a security (that is, a credit loss exists), other-than-temporary impairment is considered to have occurred. For determining the present value of variable-rate and hybrid private-label residential MBS, the Bank uses the effective interest rate derived from a variable-rate index such as one-month London Interbank Offered Rate (LIBOR) plus the contractual spread, plus or minus a fixed-spread adjustment when there is an existing discount or premium on the security. As the implied forward curve of the index changes over time, the effective interest rates derived from that index will also change over time.

In accordance with related guidance from the Federal Housing Finance Agency (Finance Agency), the Bank has contracted with the FHLBanks of San Francisco and Chicago to perform the cash-flow analysis underlying the Bank's other-than-temporary impairment decisions in certain instances. In the event that neither the FHLBank of San Francisco nor the FHLBank of Chicago has the ability to model a particular MBS owned by the Bank, the Bank projects the expected cash flows for that security based on the Bank's expectations as to how the underlying collateral and impact on deal structure resultant from collateral cash flows are forecasted to occur over time. These assumptions are based on factors including, but not limited to loan-level data for each security and modeling variables expectations for securities similar in nature modeled by either the FHLBank of San Francisco or the FHLBank of Chicago. The Bank forms these expectations for those securities by reviewing, when available, loan-level data for each such security, and, when such loan-level data is not available for a security, by reviewing loan-level data for similar loan pools as a proxy for such data.

Specifically, the Bank has contracted with the FHLBank of San Francisco to perform cash-flow analyses for its residential private-label MBS other than subprime private-label MBS, and with the FHLBank of Chicago to perform cash-flow analyses for its subprime private-label MBS. The following table summarizes the analyses of the FHLBanks contracted to perform cash-flow analysis for the Bank (dollars in thousands).

	September 30, 2011
	Number of Securities	Par Value		Amortized Cost		Carrying Value		Fair Value
FHLBank of San Francisco	170	$	2,502,362	$	1,972,072	$	1,533,803	$	1,450,488
FHLBank of Chicago	16	$	24,059	$	23,333	$	22,034	$	17,768
Bank's own cash-flow projections	13	$	79,054	$	64,298	$	49,141	$	42,495

To assess whether the entire amortized cost basis of private-label residential MBS will be recovered, cash-flow analyses for each of the Bank's private-label residential MBS were performed. These analyses use two third-party models.

The first third-party model considers borrower characteristics and the particular attributes of the loans underlying the Bank's securities, in conjunction with the assumptions about future changes in home prices and interest rates, and projects prepayments, defaults, and loss severities. A significant input to the first model is the forecast of future housing-price changes for the relevant states and core-based statistical areas (CBSAs), which are based upon an assessment of the individual housing markets. The term CBSA refers collectively to metropolitan and micropolitan statistical areas as defined by the United States Office of Management and Budget; as currently defined, a CBSA must contain at least one urban area of 10,000 or more people. The Bank's housing-price forecast as of September 30, 2011, assumed current-to-trough home price declines ranging from 0.0 percent (for those housing markets that are believed to have reached their trough) to 10.0 percent. For those markets for which further home price declines are anticipated, such declines were projected to occur over the three- to nine-month period beginning July 1, 2011. From the trough, home prices were projected to recover using one of five different recovery paths that vary by housing market. Under those recovery paths, home prices were projected to increase as follows:

17

	Range %
Year 1	0.0	—	2.8
Year 2	0.0	—	3.0
Year 3	1.5	—	4.0
Year 4	2.0	—	5.0
Years 5 and 6	2.0	—	6.0
Thereafter	2.3	—	5.6

The month-by-month projections of future loan performance are derived from the first model to determine projected prepayments, defaults, and loss severities. These projections are then input into a second model that calculates the projected loan-level cash flows and then allocates those cash flows and losses to the various classes in the securitization structure in accordance with the cash-flow and loss-allocation rules prescribed by the securitization structure.

The Bank does not intend to sell these securities and believes it is not more likely than not that the Bank will be required to sell these securities before the anticipated recovery of each security's remaining amortized cost basis. The Bank recorded other-than-temporary impairment credit losses of $7.2 million for the three months ended September 30, 2011. For held-to-maturity securities, the noncredit portion of an other-than-temporary impairment charge that is recognized in other comprehensive loss is accreted from accumulated other comprehensive loss to the carrying value of the security over the remaining life of the security in a prospective manner based on the amount and timing of future estimated cash flows. This accretion continues until the security is sold or matures, or an additional other-than-temporary impairment charge is recorded in earnings, which could result in a reclassification adjustment and the establishment of a new amount to be accreted. For the three months ended September 30, 2011, the Bank accreted $35.3 million of noncredit impairment from accumulated other comprehensive loss to the carrying value of held-to-maturity securities. For certain other-than-temporarily impaired securities that were previously impaired and have subsequently incurred additional credit losses during the three months ended September 30, 2011, the additional credit losses, up to the amount in accumulated other comprehensive loss, were reclassified out of noncredit-related losses in accumulated other comprehensive loss and charged to earnings. This amount was $4.1 million for the three months ended September 30, 2011.

For those securities for which an other-than-temporary impairment was determined to have occurred during the quarter ended September 30, 2011 (that is, a determination was made that less than the entire amortized cost basis is expected to be recovered), the following table presents a summary of the average projected values over the remaining lives of the securities for the significant inputs used to measure the amount of the credit loss recognized in earnings during the three months ended September 30, 2011, as well as related current credit enhancement. Credit enhancement is defined as the percentage of subordinated tranches and over-collateralization, if any, in a security structure that will generally absorb losses before the Bank will experience a loss on the security. The calculated averages represent the dollar-weighted averages of all the private-label residential MBS and home equity loan investments in each category shown (dollars in thousands).

rather than the classification of the security at the time of issuance.

Certain private-label MBS owned by the Bank are insured by third-party bond insurers (monoline insurers). The FHLBanks performed analyses to assess the financial strength of these monoline insurers to establish an expected case regarding the time horizon of the bond insurers' ability to fulfill their financial obligations and provide credit support. The projected time horizon of credit protection provided by an insurer is a function of claims-paying resources and anticipated claims in the future. This assumption is referred to as the “burnout period” and is expressed in months. Of the five monoline insurers, the financial guarantee from Assured Guaranty Municipal Corp. is considered sufficient to cover all future claims and is, therefore, excluded from the burnout analysis discussed above. Conversely, the burnout period for three monoline insurers, Syncora Guarantee Inc., Financial Guarantee Insurance Corp., and Ambac Assurance Corp. (Ambac), are not considered applicable due to regulatory intervention that has generally suspended all claims payments to effectively zero. For the remaining monoline insurer, MBIA Insurance Corp. (MBIA), the burnout period as of September 30, 2011, is three months, ending December 31, 2011. No securities guaranteed by MBIA were determined to have an other-than-temporary impairment credit loss at September 30, 2011.

The Bank offers callable advances that provide members with the right, based upon predetermined option exercise dates, to call the advance prior to maturity without incurring prepayment or termination fees (callable advances). Other advances may only be prepaid by paying a fee to the Bank (prepayment fee) that makes the Bank financially indifferent to the prepayment of the advance. At September 30, 2011, and December 31, 2010, the Bank had callable advances outstanding totaling $2.5 million and $11.5 million, respectively.

The following table summarizes advances outstanding by year of contractual maturity or next call date for callable advances (dollars in thousands):

The Bank also offers putable advances that provide the Bank with the right to put the fixed-rate advance to the member (and thereby extinguish the advance) on predetermined exercise dates, and offer, subject to certain conditions, replacement funding at then-current Bank rates. Generally, such put options are exercised when interest rates increase. At September 30, 2011, and December 31, 2010, the Bank had putable advances outstanding totaling $5.2 billion and $6.8 billion, respectively.

The following table summarizes advances outstanding by year of contractual maturity or next put date for putable advances (dollars in thousands):

At September 30, 2011, 42.0 percent of the Bank's fixed-rate advances were swapped to a floating rate and 0.5 percent of the Bank's variable-rate advances were swapped to a different variable-rate index.

At December 31, 2010, 45.9 percent of the Bank's fixed-rate advances were swapped to a floating rate and 0.6 percent of the Bank's variable-rate advances were swapped to a different variable-rate index.

Credit Risk Exposure and Security Terms.

The Bank's potential credit risk from advances is principally concentrated in commercial banks, savings institutions, and credit unions. At September 30, 2011, and December 31, 2010, the Bank had $6.5 billion and $8.8 billion, respectively, of advances outstanding that were greater than or equal to $1.0 billion per borrower. These advances were made to two borrowers at September 30, 2011, and three borrowers at December 31, 2010, representing 26.8 percent and 32.2 percent, respectively, of total advances outstanding.

22

The Bank lends to its members and state and local housing authorities (housing associates) chartered within the six New England states in accordance with federal statutes, including the Federal Home Loan Bank Act of 1932, as amended (the FHLBank Act). The FHLBank Act generally requires the Bank to hold, or have access to, collateral to secure the Bank's advances. While the Bank has never experienced a credit loss on an advance to a borrower, weakening economic conditions, severe credit market conditions, along with the expanded statutory collateral rules for community financial institutions (CFIs) and the incremental risk inherent in lending to housing associates, insurance companies, and community development financial institutions, provide the potential for additional credit risk for the Bank. The Bank has policies and procedures in place to manage credit risk including, without limitation, requirements for physical possession or control of pledged collateral, restrictions on borrowing, specific review of each advance request, verifications of collateral, and continuous monitoring of borrowings and the borrower's financial condition. Based on the collateral pledged as security for advances, management's credit analysis of the borrower's financial condition, and credit extension and collateral policies, the Bank does not expect any losses on advances and expects to collect all amounts due according to the contractual terms of the advances. Therefore, the Bank has not provided any allowance for losses on advances. For information related to the Bank's credit risk on advances and allowance for credit losses, see Note 9 — Allowance for Credit Losses.

Note 8 — Mortgage Loans Held for Portfolio

The Bank invests in fixed-rate single-family mortgages through the Mortgage Partnership Finance® (MPF®) program. These investments in mortgage loans are guaranteed or insured by federal agencies or are credit-enhanced by participating financial institutions. All such mortgage loans are held for portfolio. These investments in mortgage loans are originated and credit-enhanced by the originating institution. The majority of these loans are serviced by the originating institution. A portion of these loans are sold servicing-released by the participating financial institution and serviced by a third party servicer.

Note 9 — Allowance for Credit Losses

Allowance for Credit Losses Policy

An allowance for credit losses is a valuation allowance separately established for each identified portfolio segment, if necessary, to provide for probable losses inherent in the Bank's portfolio as of the statement of condition date. To the extent necessary, an allowance for credit losses for off-balance-sheet credit exposure is recorded as a liability.

Portfolio Segments. The Bank has established an allowance methodology for each of the Bank's portfolio segments. A portfolio segment is defined as the level at which an entity develops and documents a systematic method for determining its allowance for credit losses. The Bank has developed and documented a systematic methodology for determining an allowance for credit losses for 1) advances, letters of credit, and other extensions of credit to members, collectively referred to as credit products; 2) government-guaranteed or -insured mortgage loans held for portfolio; 3) conventional mortgage loans held for portfolio; 4) securities purchased under agreements to resell; and 5) federal funds sold.

Classes of Financing Receivables. Classes of financing receivables generally are a disaggregation of a portfolio segment to the extent that it is needed to understand the exposure to credit risk arising from these financing receivables. The Bank determined that no further disaggregation of portfolio segments identified above is needed as the credit risk arising from these financing receivables is assessed and measured by the Bank at the portfolio segment level.

Impairment Methodology. A loan is considered impaired when, based on current information and events, it is probable that the Bank will be unable to collect all amounts due according to the contractual terms of the loan agreement.

Loans that are on nonaccrual status and that are considered collateral-dependent are measured for impairment based on the fair value of the underlying property less estimated selling costs. Loans are considered collateral-dependent if repayment is expected to be provided solely by the sale of the underlying property, that is, there is no other available and reliable source of repayment. Collateral-dependent loans are impaired if the fair value of the underlying collateral is insufficient to recover the unpaid principal balance on the loan. Interest income on impaired loans is recognized in the same manner as nonaccrual loans as discussed below.

Nonaccrual Loans. The Bank places conventional mortgage loans on nonaccrual status when the collection of the contractual principal or interest is 90 days or more past due. When a conventional mortgage loan is placed on nonaccrual status, accrued but uncollected interest is reversed against interest income in the current period. The Bank generally records cash payments received on nonaccrual loans first as interest income and then as a reduction of principal as specified in the contractual agreement, unless the collection of the remaining principal amount due is considered doubtful. If the collection of the remaining principal amount due is considered doubtful, cash payments received would be applied first solely to principal until the remaining principal amount due is expected to be collected and then as a recovery of any charge-off, if applicable, followed by recording interest income. A loan on nonaccrual status may be restored to accrual status when the collection of the contractual principal and interest is less than 90 days past due. Government-insured and -guaranteed loans are not placed on nonaccrual status when the collection of the contractual principal or interest is 90 days or more past due because of (1) the U.S. government guarantee of the loan and (2) the contractual obligation of the loan servicer.

Charge-Off Policy. The Bank evaluates whether to record a charge-off on a conventional mortgage loan upon the occurrence of a confirming event. Confirming events include, but are not limited to, the occurrence of foreclosure or notification of a claim against any of the credit enhancements. A charge-off is recorded if the Bank determines that the recorded investment in the loan is not likely to be recovered.

Credit Products

The Bank manages its credit exposure to credit products through an integrated approach that generally provides for a credit limit to be established for each borrower, includes an ongoing review of each borrower's financial condition, and is coupled with conservative collateral/lending policies to limit risk of loss while balancing borrowers' needs for a reliable source of funding. In addition, the Bank lends in accordance with federal statutes and Finance Agency regulations. Specifically, the Bank complies with the FHLBank Act, which requires the Bank to obtain sufficient collateral to fully secure credit products. The estimated value of the collateral pledged to secure each member's credit products is calculated by applying collateral discounts, or haircuts, to the value of the collateral. The Bank accepts certain investment securities, residential mortgage loans, deposits, and other real estate related assets as collateral. The Bank requires all borrowers that pledge securities collateral to place physical possession of such securities collateral with the Bank's safekeeping agent or the borrower's securities corporation, subject to a control agreement giving the Bank appropriate control over such collateral. In addition, CFIs are eligible to use expanded statutory collateral provisions for small-business and agriculture loans. The Bank's capital stock owned by members

24

is also pledged as collateral. Collateral arrangements may vary depending upon borrower credit quality, financial condition, performance, borrowing capacity, and overall credit exposure to the borrower. The Bank can call for additional or substitute collateral to protect its security interest. Management believes these policies effectively manage the Bank's respective credit risk from credit products.

Based upon the financial condition of the borrower, the Bank may allow the borrower to retain possession of loan collateral pledged to the Bank while agreeing to hold such collateral for the benefit of the Bank or require the borrower to specifically assign or place physical possession of such loan collateral with the Bank or a third-party custodian approved by the Bank.

The Bank is provided an additional safeguard for its security interests by Section 10(e) of the FHLBank Act, which affords any security interest granted by a member or borrower to the Bank priority over the claims and rights of any other party. The exceptions to this prioritization are limited to claims that would be entitled to priority under otherwise applicable law and are held by bona fide purchasers for value or by secured parties with higher priority perfected security interests. However, the priority granted to the security interests of the Bank under Section 10(e) of the FHLBank Act may not apply when lending to insurance company members. This is due to the anti-preemption provision contained in the McCarran-Ferguson Act in which the U.S. Congress (Congress) declared that federal law would not preempt state insurance law unless the federal law expressly regulates the business of insurance. Thus, if state law conflicts with Section 10(e) of the FHLBank Act, the protection afforded by this provision may not be available to the Bank. However, the Bank perfects its security interests in the collateral pledged by its members, including insurance company members, by filing UCC-1 financing statements, or by taking possession or control of such collateral, or by taking other appropriate steps.

Using a risk-based approach and taking into consideration each borrower's financial strength, the Bank considers the types and level of collateral to be the primary indicator of credit quality on its credit products. At September 30, 2011, the Bank had rights to collateral, on a borrower-by-borrower basis, with an estimated value in excess of its outstanding extensions of credit. The estimated value of the collateral required to secure each member's obligations is calculated by applying collateral discounts or haircuts.

The Bank continues to evaluate and make changes to its collateral guidelines, as the Bank believes necessary, based on current market conditions. At September 30, 2011, and December 31, 2010, the Bank did not have any credit products that were past due, on nonaccrual status, or considered impaired. In addition, there have been no troubled debt restructurings related to credit products during the nine months ended September 30, 2011 and 2010.

Based upon the collateral held as security, its credit extension and collateral policies, management's credit analysis, and the repayment history on credit products, the Bank has not recorded any allowance for credit losses on credit products at September 30, 2011, and December 31, 2010. At September 30, 2011, and December 31, 2010, no liability to reflect an allowance for credit losses for off-balance-sheet credit exposures was recorded. See Note 18 — Commitments and Contingencies for additional information on the Bank's off-balance-sheet credit exposure.

MortgageLoans- Government-insured or -guaranteed

The Bank invests in government-insured or -guaranteed fixed-rate mortgage loans secured by one- to four-family residential properties. Government-guaranteed mortgage loans are mortgage loans insured or guaranteed by the Federal Housing Administration, the Department of Veterans Affairs, the Rural Housing Service of the Department of Agriculture, and/or by the U.S. Department of Housing and Urban Development. The servicer provides and maintains insurance or a guaranty from the applicable government agency. The servicer is responsible for compliance with all government agency requirements and for obtaining the benefit of the applicable insurance or guaranty with respect to defaulted government-guaranteed mortgage loans. Any losses incurred on such loans that are not recovered from the issuer or guarantor are absorbed by the servicers. Therefore, the Bank only has credit risk for these loans if the servicers fail to pay for losses not covered by the applicable government agency. Based on the Bank's assessment of its servicers for these loans, there is no allowance for credit losses for the government-insured and -guaranteed mortgage loans portfolio as of September 30, 2011, and December 31, 2010. In addition, due to the government guarantee or insurance, these mortgage loans are not placed on nonaccrual status.

Mortgage Loans - Conventional

The allowance for conventional mortgage loans is determined by analysis that includes consideration of various data including past performance, current performance, loan portfolio characteristics, collateral-related characteristics, the state of the housing industry, and prevailing economic conditions. The measurement of the allowance for loan losses may consist of (1) reviewing all residential mortgage loans as pool loans based on individual master commitments; (2) reviewing specifically identified collateral-dependent loans for impairment; (3) reviewing homogeneous pools of residential mortgage loans; and/or

25

(4) estimating credit losses in the remaining portfolio.

The Bank's allowance for credit losses factors in the credit enhancements associated with conventional mortgage loans (which may include primary or supplemental mortgage insurance) under the MPF program. Any incurred losses that would be recovered from the credit enhancements are not reserved as part of the Bank's allowance for loan losses. In such cases, a receivable is generally established to reflect the expected recovery from credit-enhancement arrangements. The Bank records credit-enhancement fees paid to participating financial institutions as a reduction to mortgage-loan-interest income. The Bank incurred credit-enhancement fees of $762,000 and $838,000 for the three months ended September 30, 2011 and 2010, respectively. For the nine months ended September 30, 2011 and 2010, the Bank incurred credit-enhancement fees of $2.3 million and $2.6 million respectively.

For conventional mortgage loans, credit losses that are not paid by primary mortgage insurance are allocated to the Bank up to the first-loss account. The aggregated amount of the first-loss account is documented and tracked but is neither recorded nor reported as an allowance for loan losses in the Bank's financial statements. As credit and special hazard losses are realized that are not covered by the liquidation value of the real property or primary mortgage insurance, they are first charged to the Bank, with a corresponding reduction of the first-loss account for that master commitment up to the amount accumulated in the first-loss account at that time. Over time, the first-loss account may cover the expected credit losses on a master commitment, although losses that are greater than expected or that occur early in the life of the master commitment could exceed the amount accumulated in the first-loss account. In that case, the excess losses would be charged next to the member's credit-enhancement amount, then to the Bank after the member's credit-enhancement amount has been exhausted. The amount of the first-loss account remaining to absorb losses for loans owned by the Bank is partly dependent on the percentage of loans owned by the Bank that are within master commitments which include loans that are owned, in whole or in part, by other MPF Banks. Assuming losses occur on a proportional basis between loans owned by the Bank and loans owned by other MPF Banks, at September 30, 2011, and December 31, 2010, the amount of first-loss account remaining for losses attributable to the Bank was $24.4 million and $27.8 million, respectively. For certain MPF products, the Bank's losses incurred under the first-loss account can be mitigated by withholding future performance credit-enhancement fees that would otherwise be payable to the participating financial institutions.

Collectively Evaluated Mortgage Loans. The credit risk analysis of conventional mortgage loans evaluated collectively for impairment considers loan-pool-specific attribute data at the master commitment pool level, applies estimated loss severities, and incorporates the credit enhancements of the MPF program. Migration analysis is a methodology for estimating, through the Bank's experience over a historical period, the rate of default experienced on pools of similar loans. The Bank applies migration analysis to loans based on its experience with loans that are currently not past due, loans that are 30 to 59 days past due, 60 to 89 days past due, and 90 or more days past due, as well as to loans 60 or more days past due following receipt of notice of filing from the bankruptcy court. The Bank then estimates the dollar amount of loans in these categories that may migrate to a realized loss position and apply a loss severity factor to estimate losses incurred at the statement of condition date.

Individually Evaluated Mortgage Loans. Certain conventional mortgage loans (typically impaired mortgage loans that are considered collateral dependent), may be specifically identified for purposes of calculating the allowance for credit losses.

A mortgage loan is considered collateral dependent if repayment is only expected to be provided by the sale of the underlying property, that is, if it is considered likely that the borrower will default and there is no credit enhancement from a participating financial institution to offset losses under the master commitment. The estimated credit losses on impaired collateral-dependent loans may be separately determined because sufficient information exists to make a reasonable estimate of the inherent loss for such loans on an individual loan basis. The Bank applies an estimated loss severity rate, which is used to estimate the fair value of the collateral. The resulting loss recorded is equal to the carrying value of the loan less the estimated fair value of the collateral less estimated selling costs.

Estimating Credit Loss in the Remaining Portfolio. The Bank also assesses a factor for the margin for imprecision to the estimation of credit losses for the homogeneous population. The margin for imprecision is a factor in the allowance for credit losses that recognizes the imprecise nature of the measurement process and is included as part of the mortgage loan allowance for credit loss. This amount represents a subjective management judgment based on facts and circumstances that exist as of the reporting date that is unallocated to any specific measurable economic or credit event and is intended to cover other inherent losses that may not be captured in the methodology described within. The actual loss that may occur on homogeneous populations of mortgage loans may be more or less than the estimated loss.

Roll-Forward of Allowance for Credit Losses on Mortgage Loans. As of September 30, 2011, and December 31, 2010, the Bank determined that an allowance for credit losses should be established for credit losses on its conventional mortgage loans. The following table presents a roll-forward of the allowance for credit losses on mortgage loans for the three and nine months endedSeptember 30, 2011 and 2010, as well as the recorded investment in mortgage loans by impairment methodology at

26

September 30, 2011 (dollars in thousands). The recorded investment in a loan is the par amount of the loan, adjusted for accrued interest, unamortized premiums or discounts, deferred derivative gains and losses, and direct write-downs. The recorded investment is not net of any valuation allowance.

Troubled Debt Restructurings.

Troubled debt restructuring is considered to have occurred when a concession is granted to the debtor that would not otherwise be considered for economic or legal reasons related to the debtor's financial difficulties.

The Bank's program for MPF loan troubled debt restructurings primarily involve modifying the borrower's monthly payment for a period of up to 36 months to no more than a housing expense ratio of 38 percent of their monthly income. The outstanding principal balance is re-amortized to reflect a principal and interest payment for a term not to exceed 40 years and a housing expense ratio not to exceed 38 percent. This would result in a balloon payment at the original maturity date of the loan as the maturity date and number of remaining monthly payments is unchanged. If the 38 percent ratio is still not met, the interest rate is reduced for up to 36 months in 0.125 percent increments below the original note rate, to a floor rate of 3.00 percent, resulting in reduced principal and interest payments, until the target 38 percent housing expense ratio is met.

As discussed in Note 2 — Recently Issued Accounting Standards and Interpretations, the Bank adopted amended guidance intended to clarify which debt modifications constitute troubled debt restructurings. The Bank has had no new modifications that occurred on or after January 1, 2011, and did not identify any additional troubled debt restructurings as a result of adopting this amended guidance.

As of September 30, 2011, and December 31, 2010, the Bank had one MPF loan with a recorded investment of $245,000 and $238,000, respectively that is considered a troubled debt restructuring. As of September 30, 2011, the Bank's one troubled debt restructuring was performing and had not defaulted.

Real Estate Owned Assets.

The Bank's REO includes assets that have been received in satisfaction of debt or as a result of actual foreclosures. REO is initially recorded as other assets in the statement of condition and is carried at the lower of cost or fair value less estimated selling costs. Fair value is defined as the amount that a willing seller could expect from a willing buyer in an arm's-length transaction. If the fair value of the REO is less than the recorded investment in the MPF loan at the date of transfer, the Bank recognizes a charge-off to the allowance for credit losses. Subsequent realized gains and realized or unrealized losses are

28

included in other income (loss) in the statement of operations.

At September 30, 2011, and December 31, 2010, the Bank had $6.3 million and $6.5 million, respectively, in assets classified as REO. During the nine months ended September 30, 2011 and 2010, the Bank sold REO assets with a recorded carrying value of $7.5 million and $6.8 million, respectively. Upon sale of these properties, and inclusive of any proceeds received from primary mortgage-insurance coverage, the Bank recognized net gains totaling $400,000 and $226,000 on the sale of REO assets during the nine months ended September 30, 2011 and 2010, respectively. Gains and losses on the sale of REO assets are recorded in other income.

Federal Funds Sold and Securities Purchased Under Agreements to Resell

These investments are all short-term (all less than three months) and the recorded balance approximates fair value. The Bank invests in federal funds sold with highly rated counterparties and are only evaluated for purposes of an allowance for credit losses if the investment is not paid when due. All investments in federal funds sold as of September 30, 2011, and December 31, 2010, were repaid according to the contractual terms. Securities purchased under agreements to resell are considered collateralized financing arrangements and effectively represent short-term loans to highly rated counterparties. The terms of these loans are structured such that if the market value of the underlying securities decreases below the market value required as collateral, the counterparty must provide additional securities as collateral in an amount equal to the decrease or remit cash in such amount, or the dollar value of the resale agreement will be decreased accordingly. If an agreement to resell is deemed to be impaired, the difference between the fair value of the collateral and the amortized cost of the agreement is charged to earnings. Based upon the collateral held as security, the Bank determined that no allowance for credit losses was needed for the securities purchased under agreements to resell at September 30, 2011, and December 31, 2010.

Purchases, Sales, and Reclassifications

During the nine months ended September 30, 2011, there were no significant purchases or sales of financing receivables. Furthermore, there were no reclassifications of financing receivables to held for sale during the period.

Note 10 — Derivatives and Hedging Activities

All derivatives are recognized on the statement of condition at fair value. The Bank offsets fair-value amounts recognized for derivative instruments and fair-value amounts recognized for the right to reclaim cash collateral (a receivable) or the obligation to return cash collateral (a payable) arising from derivative instruments recognized at fair value executed with the same counterparty under a master-netting arrangement. Derivative assets and derivative liabilities reported on the statement of condition also include net accrued interest.

Each derivative is designated as one of the following:

(1)a qualifying hedge of the change in fair value of a recognized asset or liability or an unrecognized firm commitment (a fair-value hedge);

(2)a qualifying hedge of a forecasted transaction or the variability of cash flows that are to be received or paid in connection with a recognized asset or liability (a cash-flow hedge);

(3)a nonqualifying hedge of an asset or liability (economic hedge) for asset-liability-management purposes; or

(4)a nonqualifying hedge of another derivative (an intermediation instrument) that is offered as a product to members or used to offset other derivatives with nonmember counterparties.

Accounting for Qualifying Hedges. If hedging relationships meet certain criteria, including, but not limited to, formal documentation of the hedging relationship and an expectation to be highly effective, they qualify for hedge accounting and the offsetting changes in fair value of the hedged items may be recorded either in earnings (fair-value hedges) or accumulated other comprehensive loss (cash-flow hedges). Two approaches to hedge accounting include:

(1) Long-haul hedge accounting - The application of long-haul hedge accounting generally requires the Bank to formally assess (both at the hedge's inception and at least quarterly) whether the derivatives that are used in hedging transactions have been effective in offsetting changes in the fair value or cash flows of hedged items or forecasted transactions and whether those derivatives may be expected to remain effective in future periods. 

(2) Short-cut hedge accounting - Transactions that meet certain criteria qualify for the short-cut method of hedge

29

accounting in which an assumption can be made that the change in fair value of a hedged item, due to changes in the benchmark rate, exactly offsets the change in fair value of the related derivative. Under the shortcut method, the entire change in fair value of the interest-rate swap is considered to be effective at achieving offsetting changes in fair values or cash flows of the hedged asset or liability.

Derivatives that are used in fair-value hedges are typically executed at the same time as the hedged items, and the Bank designates the hedged item in a qualifying hedge relationship as of the trade date. In many hedging relationships that use the shortcut method, the Bank may designate the hedging relationship upon its commitment to disburse an advance or trade a consolidated obligation (CO) that settles within the shortest period of time possible for the type of instrument based on market-settlement conventions. In such circumstances, although the advance or CO will not be recognized in the financial statements until settlement date, the hedge meets the criteria for applying the short-cut method, provided all other short-cut criteria are also met. The Bank then records the changes in fair value of the derivative and the hedged item beginning on the trade date.

Changes in the fair value of a derivative that is designated and qualifies as a fair-value hedge, along with changes in the fair value of the hedged asset or liability that are attributable to the hedged risk (including changes that reflect losses or gains on firm commitments), are recorded in other income (loss) as net gains (losses) on derivatives and hedging activities.

Changes in the fair value of a derivative that is designated and qualifies as a cash-flow hedge, to the extent that the hedge is effective, are recorded in accumulated other comprehensive loss, a component of capital, until earnings are affected by the variability of the cash flows of the hedged transaction.

For both fair-value and cash-flow hedges, any hedge ineffectiveness (which represents the amount by which the changes in the fair value of the derivative differ from the change in the fair value of the hedged item or the variability in the cash flows of the forecasted transaction) is recorded in other income (loss) as net gains (losses) on derivatives and hedging activities.

Accounting for Nonqualifying Hedges. An economic hedge is defined as a derivative hedging specific or nonspecific assets, liabilities, or firm commitments that does not qualify or was not designated for hedge accounting, but is an acceptable hedging strategy under the Bank's risk-management policy. These economic hedging strategies also comply with Finance Agency regulatory requirements prohibiting speculative derivative transactions. An economic hedge by definition introduces the potential for earnings variability caused by the changes in fair value of the derivatives that are recorded in income but not offset by corresponding changes in the fair value of the economically hedged assets, liabilities, or firm commitments. As a result, the Bank recognizes only the net interest and the change in fair value of these derivatives in other income (loss) as net gains (losses) on derivatives and hedging activities with no offsetting fair-value adjustments for the economically hedged assets, liabilities, or firm commitments. Cash flows associated with such stand-alone derivatives (derivatives not qualifying as a hedge) are reflected as cash flows from operating activities in the statement of cash flows unless the derivative meets the criteria to be a financing derivative.

Accrued Interest Receivable and Payable. The differential between accrual of interest receivable and payable on derivatives designated as a fair-value hedge or as a cash-flow hedge is recognized through adjustments to the interest income or interest expense of the designated hedged investment securities, advances, COs, deposits, or other financial instruments. The differential between accrual of interest receivable and payable on intermediated derivatives for members and other economic hedges is recognized in other income (loss), along with changes in fair value of these derivatives, as net gains (losses) on derivatives and hedging activities.

Discontinuance of Hedge Accounting. The Bank may discontinue hedge accounting prospectively when: (1) it is determined that the derivative is no longer effective in offsetting changes in the fair value or cash flows of a hedged item (including hedged items such as firm commitments or forecasted transactions); (2) the derivative and/or the hedged item expires or is sold, terminated, or exercised; (3) it is no longer probable that the forecasted transaction will occur in the originally expected period; (4) a hedged firm commitment no longer meets the definition of a firm commitment; or (5) management determines that designating the derivative as a hedging instrument is no longer appropriate.

When hedge accounting is discontinued because the Bank determines that the derivative no longer qualifies as an effective fair-value hedge of an existing hedged item, the Bank either terminates the derivative or continues to carry the derivative on the statement of condition at its fair value, ceases to adjust the hedged asset or liability for changes in fair value, and begins to amortize the cumulative basis adjustment on the hedged item into earnings over the remaining life of the hedged item using the level-yield method.

When hedge accounting is discontinued because the Bank determines that the derivative no longer qualifies as an effective cash-flow hedge of an existing hedged item, the Bank continues to carry the derivative on the statement of condition at its fair

30

value and amortizes the cumulative other comprehensive loss adjustment to earnings when earnings are affected by the existing hedged item.

Under limited circumstances, when the Bank discontinues cash-flow hedge accounting because it is no longer probable that the forecasted transaction will occur in the originally expected period plus the following two months, but it is probable that the transaction will still occur in the future, the gain or loss on the derivative remains in accumulated other comprehensive loss and is recognized in earnings when the forecasted transaction affects earnings. However, if it is probable that a forecasted transaction will not occur by the end of the originally specified time period or within two months thereafter, the gain or loss that was accumulated in other comprehensive loss is recognized immediately in earnings.

When hedge accounting is discontinued because the hedged item no longer meets the definition of a firm commitment, the Bank continues to carry the derivative on the statement of condition at its fair value, removing from the statement of condition any asset or liability that was recorded to recognize the firm commitment and recording it as a gain or loss in current period earnings.

Embedded Derivatives. The Bank may issue debt, make advances, or purchase financial instruments in which a derivative instrument is embedded. Upon execution of these transactions, the Bank assesses whether the economic characteristics of the embedded derivative are clearly and closely related to the economic characteristics of the remaining component of the advance, debt, deposit, or other financial instrument (the host contract) and whether a separate, nonembedded instrument with the same terms as the embedded instrument would meet the definition of a derivative instrument. When the Bank determines that (1) the embedded derivative has economic characteristics that are not clearly and closely related to the economic characteristics of the host contract and (2) a separate, stand-alone instrument with the same terms would qualify as a derivative instrument, the embedded derivative is separated from the host contract, carried at fair value, and designated as a stand-alone derivative instrument. If the entire contract (the host contract and the embedded derivative) is to be measured at fair value, with changes in fair value reported in current earnings (for example, an investment security classified as trading, as well as hybrid financial instruments) or if the Bank cannot reliably identify and measure the embedded derivative for purposes of separating that derivative from its host contract, the entire contract is carried on the statement of condition at fair value and no portion of the contract is designated as a hedging instrument. The Bank has determined that all embedded derivatives in currently outstanding transactions as of September 30, 2011, are clearly and closely related to the host contracts, and therefore no embedded derivatives have been bifurcated from the host contract.

Credit Risk. The table below presents credit-risk exposure on derivative instruments, excluding instances where a counterparty's pledged cash collateral to the Bank exceeds the Bank's net position (dollars in thousands).

	September 30, 2011		December 31, 2010
Total net exposure at fair value(1)	$	28,924	$	17,098
Cash collateral held	12,511		2,280
Net exposure after collateral	$	16,413	$	14,818

_______________________

(1)  Includes net accrued interest receivable of $1.2 million and $2.2 million at September 30, 2011, and December 31, 2010, respectively.

Certain of the Bank's derivative instruments contain provisions that require the Bank to post additional collateral with its counterparties if there is deterioration in the Bank's credit ratings. Under the terms that govern such instruments, if the Bank's credit rating is lowered by an NRSRO, the Bank is required to deliver additional collateral on derivative instruments in a net liability position. In the event of a split among such credit ratings, the lower ratings govern. The aggregate fair value of all derivative instruments with credit-risk-related contingent features that were in a net liability position (before cash collateral and related accrued interest) at September 30, 2011, was $896.4 million for which the Bank had delivered collateral with a post-haircut value of $773.3 million in the normal course of business. The following table sets forth the post-haircut value of incremental collateral that certain swap counterparties could have required the Bank to deliver based on incremental credit rating downgrades at September 30, 2011.

(1) Ratings are expressed in this table according to Standard & Poor's Rating Service's (S&P's) conventions but include the equivalent of such rating by Moody's Investor Services (Moody's).

(2) Additional collateral of $21.9 million is required as of September 30, 2011 at a rating of AA+ and is not included in the table.

The Bank executes derivatives with nonmember counterparties with long-term ratings of single-A (or equivalent) or better by S&P and Moody's at the time of the transaction, although risk-reducing trades may be approved for counterparties whose ratings have fallen below these ratings. Some of these counterparties or their affiliates buy, sell, and distribute COs. See Note 12 — Consolidated Obligations for additional information. Note 18 — Commitments and Contingencies discusses assets pledged by the Bank to these counterparties. The Bank is not a derivatives dealer and does not trade derivatives for short-term profit.

(1)  The net interest on derivatives in fair-value hedge relationships is presented in the interest income or interest expense of the respective hedged item in the statement of operations.

The loss recognized in accumulated other comprehensive loss for hedged items in cash-flow hedging relationships was $25.2 million for the three months ended September 30, 2011. The loss recognized in accumulated other comprehensive loss for hedged items in cash-flow hedging relationships was $26.8 million for the nine months ended September 30, 2011. The Bank had no derivatives and hedged items in cash-flow hedging relationships during the three and nine months ended September 30,

33

2010.

For the three and nine months ended September 30, 2011 and 2010, there were no reclassifications from other comprehensive loss into earnings as a result of the discontinuance of cash-flow hedges because the original forecasted transactions were not expected to occur by the end of the originally specified time period or within a two-month period thereafter.

As of September 30, 2011, none of the Bank's unrecognized net losses on derivative instruments accumulated in other comprehensive loss are expected to be reclassified to earnings during the next 12 months. The maximum length of time over which the Bank is hedging its exposure to the variability in future cash flows for forecasted transactions is three years.

The notional amount of derivatives serves as a factor in determining periodic interest payments or cash flows received and paid. However, the notional amount of derivatives represents neither the actual amounts exchanged nor the overall exposure of the Bank to credit and market risk. The risks of derivatives can be measured meaningfully on a portfolio basis that takes into account the derivatives, the item being hedged, and any offsets between the two.

The following table presents the fair value of derivative instruments as of September 30, 2011 (dollars in thousands):

	Notional Amount of Derivatives		Derivative Assets			Derivative Liabilities

Note 11 — Deposits

The Bank offers demand and overnight deposits for members and qualifying nonmembers. In addition, the Bank offers short-term interest-bearing deposit programs to members. Members that service mortgage loans may deposit in the Bank funds collected in connection with mortgage loans pending disbursement of such funds to the owners of the mortgage loans; the Bank classifies these items as other in the following table.    

Deposits at September 30, 2011, and December 31, 2010, include hedging adjustments of $4.4 million and $4.8 million, respectively.

Note 12 — Consolidated Obligations

COs consist of CO bonds and CO discount notes. CO bonds are issued primarily to raise intermediate and long-term funds for the FHLBanks and are not subject to any statutory or regulatory limits on maturity. CO discount notes are issued to raise short-term funds. These notes sell at less than their face amount and are redeemed at par value when they mature.

Note 14 — Capital

The Bank is subject to three capital requirements under its capital structure plan and Finance Agency rules and regulations:

1.Risk-based capital. Under this capital requirement, the Bank must maintain at all times permanent capital, defined as Class B stock and retained earnings, in an amount at least equal to the sum of its credit-risk capital requirement, its market-risk capital requirement, and its operations-risk capital requirement, calculated in accordance with Bank policy and Finance Agency rules and regulations, referred to herein as the risk-based capital requirement. Only permanent capital satisfies this risk-based capital requirement. The Finance Agency may require the Bank to maintain a greater amount of permanent capital than is required as defined by the risk-based capital requirements.

2.Total regulatory capital. Under this capital requirement, the Bank is required to maintain at all times a total capital-to-assets ratio of at least 4 percent. Total regulatory capital is the sum of permanent capital, any general loss allowance if consistent with GAAP and not established for specific assets, and other amounts from sources determined by the Finance Agency as available to absorb losses.

3.Leverage capital. Under this third capital requirement, the Bank is required to maintain at all times a leverage capital-to-assets ratio of at least 5 percent. A leverage capital-to-assets ratio is defined as permanent capital weighted 1.5 times divided by total assets.

Mandatorily redeemable capital stock, which is classified as a liability under GAAP, is considered capital for determining the Bank's compliance with its regulatory capital requirements.

The following tables demonstrate the Bank's compliance with its regulatory capital requirements at September 30, 2011, and December 31, 2010 (dollars in thousands):

Joint Capital Enhancement Agreement

The 12 FHLBanks entered into a Joint Capital Enhancement Agreement (the Capital Agreement), as amended, which is intended to enhance the capital position of each FHLBank. The intent of the Capital Agreement is to allocate that portion of each FHLBank's earnings historically paid to satisfy its REFCorp obligation to a separate retained earnings account at that FHLBank.

Because each FHLBank has been required to contribute 20 percent of its earnings toward payment of the interest on REFCorp bonds until the REFCorp obligation was satisfied, the Capital Agreement provides that, upon full satisfaction of the REFCorp obligation, each FHLBank will contribute 20 percent of its net income each quarter to a restricted retained earnings account until the balance of that account equals at least one percent of that FHLBank's average balance of outstanding consolidated obligations for the previous quarter. Restricted retained earnings are not available to pay dividends.

The FHLBanks subsequently amended their capital plans or capital plan submissions, as applicable, to implement the provisions of the Capital Agreement, and the Finance Agency approved the capital plan amendments on August 5, 2011.

On August 5, 2011, the Finance Agency certified that the FHLBanks have fully satisfied their REFCorp obligation. In accordance with the Capital Agreement, starting in the third quarter of 2011, each FHLBank is required to allocate 20 percent of its net income to a separate restricted retained earnings account. As of September 30, 2011, restricted retained earnings totaled $10.0 million.

Note 15 — Employee Retirement Plans

Qualified Defined Benefit Multi-Employer Plan. The Bank participates in the Pentegra Defined Benefit Plan for Financial Institutions (Pentegra Defined Benefit Plan), a funded, tax-qualified, noncontributory defined-benefit pension plan. The Pentegra Defined Benefit Plan is a multi-employer plan in which assets contributed by one participating employer may be used to provide benefits to employees of other participating employers since assets contributed by an employer are not segregated in a separate account or restricted to provide benefits only to employees of that employer. As a result, disclosure of the accumulated benefit obligations, plan assets, and the components of annual pension expense attributable to the Bank is not

38

made. The plan covers substantially all officers and employees of the Bank. Funding and administrative costs of the Pentegra Defined Benefit Plan charged to compensation and benefit expense were $1.3 million and $1.1 million for the three months ended September 30, 2011, and 2010, respectively. Funding and administrative costs of the Pentegra Defined Benefit Plan charged to compensation and benefit expense were $3.1 million and $3.4 million for the nine months ended September 30, 2011, and 2010, respectively.

Qualified Defined Contribution Plan. The Bank also participates in the Pentegra Defined Contribution Plan for Financial Institutions, a tax-qualified defined contribution plan. The plan covers substantially all officers and employees of the Bank. The Bank contributes a percentage of the participants' compensation by making a matching contribution equal to a percentage of voluntary employee contributions, subject to certain limitations. The Bank's matching contributions charged to compensation and benefit expense were $212,000 and $205,000 in the three months ended September 30, 2011 and 2010, respectively. The Bank's matching contributions charged to compensation and benefit expense were $646,000 and $621,000 for the nine months ended September 30, 2011 and 2010, respectively.

Nonqualified Defined Contribution Plan. The Bank also maintains the Thrift Benefit Equalization Plan, a nonqualified, unfunded deferred compensation plan covering certain senior officers and directors of the Bank, as defined in the plan. The plan's liability consists of the accumulated compensation deferrals and the accumulated earnings on these deferrals. The Bank recognized expenses of $16,000 and $17,000 in the three months ended September 30, 2011 and 2010, respectively, related to this plan. The Bank recognized expenses of $68,000 and $34,000 in the nine months ended September 30, 2011 and 2010, respectively, related to this plan. The Bank's obligation from this plan, was $2.9 million at both September 30, 2011, and December 31, 2010. The Bank maintains a rabbi trust intended to meet future benefit obligations.

Nonqualified Supplemental Defined Benefit Retirement Plan. The Bank also maintains a nonqualified, unfunded defined-benefit plan covering certain senior officers, as defined in the plan. The Bank maintains a rabbi trust intended to meet future benefit obligations.

Postretirement Benefits. The Bank sponsors a fully insured postretirement benefit program that includes life insurance benefits for eligible retirees. The Bank provides life insurance to all employees who retire on or after age 55 after completing six years of service. No contributions are required from the retirees. There are no funded plan assets that have been designated to provide postretirement benefits.

In connection with the nonqualified supplemental defined benefit retirement plan and postretirement benefits, the Bank recorded the following amounts as of September 30, 2011, and December 31, 2010 (dollars in thousands):

	Nonqualified Supplemental Defined Benefit Retirement Plan						Postretirement Benefits

Note 16 — Segment Information

In the first quarter of 2011, the Bank began reporting on an enterprise-wide basis rather than providing separate segment information for the MPF program. The enterprise-wide method of evaluating the Bank's financial information reflects the manner in which the chief operating decision-maker manages the business. Accordingly, the Bank will no longer present separate Mortgage Loan Finance segment information.

Fair-Value Methodologies and Techniques

The fair-value amounts above have been determined by the Bank using available market information and the Bank's best judgment of appropriate valuation methods. These estimates are based on pertinent information available to the Bank at September 30, 2011, and December 31, 2010. Although the Bank uses its best judgment in estimating the fair value of these financial instruments, there are inherent limitations in any estimation technique or valuation methodology. For example, because an active secondary market does not exist for a portion of the Bank's financial instruments, in certain cases, fair values are not subject to precise quantification or verification and may change as economic and market factors and evaluation of those factors change. Therefore, these fair values are not necessarily indicative of the amounts that would be realized in current market transactions, although they do reflect the Bank's judgment of how a market participant would estimate the fair values. The fair-value summary table above does not represent an estimate of the overall market value of the Bank as a going concern, which would take into account future business opportunities and the net profitability of assets versus liabilities.

Cash and Due from Banks. The fair value approximates the recorded carrying value.

Interest-Bearing Deposits. The fair value is determined by calculating the present value of expected future cash flows. The discount rates used in these calculations are the rates for interest-bearing deposits with similar terms.

Investment Securities. For investment securities other than HFA floating-rate obligations, the Bank requests prices from four specific third-party vendors, and, depending on the number of prices received for each security, selects a median or average price as defined by the methodology. The methodology also incorporates variance thresholds to assist in identifying median or average prices that may require further review. In certain limited instances (for example, prices are outside of variance thresholds or the third-party services do not provide a price), the Bank will obtain a price from securities dealers or internally model a price that is deemed most appropriate after consideration of all relevant facts and circumstances that would be considered by market participants. In obtaining such valuation information from third parties, the Bank generally reviews the valuation methodologies used to develop the fair values to determine whether such valuations are representative of an exit price

41

in the Bank's principal markets.

Investment Securities – Housing-Finance-Agency Floating-Rate Obligations. The fair value isdetermined by calculating the present value of the expected future cash flows. The discount rates used in these calculations are the rates for securities with similar terms.

Securities Purchased under Agreements to Resell. The fair value is determined by calculating the present value of expected future cash flows. The discount rates used in these calculations are the rates for transactions with similar terms.

Federal Funds Sold. The fair value is determined by calculating the present value of the expected future cash flows. The discount rates used in these calculations are the rates for federal funds sold with similar terms.

Advances. The Bank determines the fair value of advances by calculating the present value of expected future cash flows from the advances and excluding the amount of accrued interest receivable. The discount rates used in these calculations are the current replacement rates for advances with similar terms. In accordance with the Finance Agency's advances regulations, advances with a maturity or repricing period greater than six months require a prepayment fee sufficient to make the Bank financially indifferent to the borrower's decision to prepay the advances. Therefore, the fair value of advances does not assume prepayment risk. The Bank does not account for credit risk in determining the fair value of the Bank's advances due to the strong credit protections that mitigate the credit risk associated with advances. Collateral requirements for advances provide surety for the repayment such that the probability of credit losses on advances is very low. The Bank has the ability to establish a blanket lien on all financial assets of most members, and in the case of federally-insured depository institutions, the Bank’s lien has a statutory priority over all other creditors with respect to collateral that has not been perfected by other parties. All of these factors serve to mitigate credit risk on advances.

Mortgage Loans. The fair values for mortgage loans are determined based on quoted market prices of similar mortgage-loan pools available in the market or modeled prices adjusted for factors specific to the Bank's mortgage loans including, but not limited to, differences in coupon, average loan rate, seasoning, and cash-flow remittance between the Bank's mortgage loans and the MBS. The prices of the referenced MBS and the mortgage loans are highly dependent upon the underlying prepayment assumptions priced in the secondary market. Changes in the prepayment rates could have a material effect on the fair value. Since these underlying prepayment assumptions are made at a specific point in time, they are susceptible to material changes in the near term.

Real Estate Owned. Fair value is defined as the amount that a willing seller could expect from a willing buyer in an arm's-length transaction. If the fair value of the REO is less than the recorded investment in the MPF loan at the date of transfer, the Bank recognizes a charge-off to the allowance for credit losses. Subsequent realized gains and realized or unrealized losses are included in other income (loss) in the statement of operations.

Accrued Interest Receivable and Payable. The fair value is the recorded book value.

Derivative Assets/Liabilities – Interest-Rate-Exchange Agreements. The Bank bases the fair values of interest-rate-exchange agreements on available market prices of derivatives having similar terms, including accrued interest receivable and payable. The fair value is based on the LIBOR swap curve and forward rates at period-end and, for agreements containing options, the market's expectations of future interest-rate volatility implied from current market prices of similar options. The fair value methodology uses standard valuation techniques for derivatives such as discounted cash-flow analysis and comparisons with similar instruments. The fair values are netted by counterparty, including cash collateral received from or delivered to the counterparty, where an offset right exists. If these netted amounts are positive, they are classified as an asset, and if negative, they are classified as a liability. The Bank enters into master-netting agreements for interest-rate-exchange agreements with institutions that have long-term senior unsecured credit ratings that are at or above single-A by S&P and Moody's. The Bank establishes master-netting agreements to reduce its exposure from counterparty defaults, and enters into bilateral-collateral-exchange agreements that require credit exposures beyond a defined amount to be secured by U.S. government or GSE securities or cash. All of these factors serve to mitigate credit and nonperformance risk to the Bank.

Derivative Assets/Liabilities – Commitments to Invest in Mortgage Loans.Commitments to invest in mortgage loans are recorded as derivatives in the statement of condition. The fair values of such commitments are based on the end-of-day delivery commitment prices provided by the FHLBank of Chicago, which are derived from MBS to be announced (TBA) delivery commitment prices with adjustment for the contractual features of the MPF program, such as servicing and credit-enhancement features.

Deposits. The Bank determines fair values of deposits by calculating the present value of expected future cash flows from the

42

deposits and reducing this amount by any accrued interest payable. The discount rates used in these calculations are the cost of deposits with similar terms.

Consolidated Obligations. The Bank estimates fair values based on the cost of issuing comparable term debt, excluding noninterest selling costs. Fair values of COs without embedded options are determined based on internal valuation models which use market-based yield curve inputs obtained from the Office of Finance (the FHLBanks' agent that issues and services the Banks' COs). Fair values of COs with embedded options are determined based on internal valuation models with market-based inputs obtained from the Office of Finance and derivative dealers.

Mandatorily Redeemable Capital Stock. The fair value of capital stock subject to mandatory redemption is generally at par. Capital stock can only be acquired by the Bank's members at par value and redeemed at par value. The Bank's capital stock is not traded and no market mechanism exists for the exchange of capital stock outside the cooperative structure.

Commitments. The fair value of the Bank's standby bond-purchase agreements is based on the present value of the estimated fees the Bank is to receive for providing these agreements, taking into account the remaining terms of such agreements. For fixed-rate advance commitments, fair value also considers the difference between current levels of interest rates and the committed rates.

Estimates of the fair value of advances with options, mortgage instruments, derivatives with embedded options, and CO bonds with options are highly subjective and require judgments regarding significant matters such as the amount and timing of future cash flows, prepayment speed assumptions, expected interest-rate volatility, methods to determine possible distributions of future interest rates used to value options, and the selection of discount rates that appropriately reflect market and credit risks. Changes in these judgments often have a material effect on the fair-value estimates. Since these estimates are made as of a specific point in time, they are susceptible to material near-term changes.

Fair-Value Hierarchy. The Bank records trading securities, available-for-sale securities, derivative assets, and derivative liabilities at fair value. The transaction to sell the asset or transfer the liability is a hypothetical transaction at the measurement date, considered from the perspective of a market participant that holds the asset or owes the liability. In general, the transaction price will equal the exit price and, therefore, represents the fair value of the asset or liability at initial recognition. In determining whether a transaction price represents the fair value of the asset or liability at initial recognition, each reporting entity is required to consider factors specific to the asset or liability, the principal or most advantageous market for the asset or liability, and market participants with whom the entity would transact in that market.

The fair-value hierarchy prioritizes the inputs of valuation techniques used to measure fair value. The inputs are evaluated and an overall level within the fair-value hierarchy for the fair-value measurement is determined. This overall level is an indication of the market observability of the fair-value measurement. Fair value is the price in an orderly transaction between market participants to sell an asset or transfer a liability in the principal (or most advantageous) market for the asset or liability at the measurement date (an exit price). To determine the fair value or the exit price, entities must determine the unit of account, highest and best use, principal market, and market participants. These determinations allow the reporting entity to define the inputs for fair value and level within the fair-value hierarchy.

Outlined below is the application of the fair-value hierarchy to the Bank's financial assets and financial liabilities that are carried at fair value.

Level 1Defined as those instruments for which inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets. An active market for the asset or liability is a market in which the transactions for the asset or liability occur with sufficient frequency and volume to provide pricing information on an ongoing basis. The types of assets and liabilities carried at Level 1 fair value generally include certain types of derivative contracts that are traded in an open exchange market and investments such as U.S. Department of the Treasury (U.S. Treasury) securities.

Level 2Defined as those instruments for which inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument. The types of assets and liabilities carried at Level 2 fair value generally include investment securities, including U.S. government and agency securities, and derivative contracts.

Level 3Defined as those instruments for which inputs to the valuation methodology are unobservable and significant to the fair-value measurement. Unobservable inputs are supported by little or no market activity and reflect

43

the Bank's own assumptions. The types of assets and liabilities carried at Level 3 fair value generally include certain private-label MBS.

The Bank uses valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. Fair value is first determined based on quoted market prices or market-based prices, where available. If quoted market prices or market-based prices are not available, fair value is determined based on valuation models that use market-based information available to the Bank as inputs to the models.

Fair Value Measured on a Recurring Basis

For instruments carried at fair value, the Bank reviews the fair-value hierarchy classifications on a quarterly basis. Changes in the observability of the valuation attributes may result in a reclassification of certain financial assets or liabilities, and those reclassifications will be reported as a transfer between levels at fair value in the quarter in which the change occurs. Transfers between levels will be reported as of the beginning of the period; however the Bank did not have any transfers between levels during the nine months ended September 30, 2011.

Fair Value on a Nonrecurring Basis

The Bank measures certain held-to-maturity investment securities and REO at fair value on a nonrecurring basis; that is, they are not measured at fair value on an ongoing basis but are subject to fair-value adjustments only in certain circumstances (for example, upon recognizing an other-than-temporary impairment on a held-to-maturity security).

The following tables present the fair value of financial assets by level within the fair value hierarchy which are recorded on a nonrecurring basis at September 30, 2011, and December 31, 2010 (dollars in thousands).

Significant Inputs of Recurring and Nonrecurring Fair-Value Measurements

The following represents the significant inputs used to determine fair value of those instruments carried on the balance sheet at fair value which are classified as Level 2 or Level 3 within the fair-value hierarchy. The descriptions below do not differentiate between recurring and nonrecurring fair-value measurements and should be read in conjunction with the fair-value methodology disclosures for all financial instruments provided above.

Investment Securities. For the Bank's investment securities carried at fair value the Bank's valuation technique incorporates prices from up to four designated third-party pricing vendors when available, consistent with the method agreed upon by the FHLBanks. These pricing vendors use methods that generally employ, but are not limited to, benchmark yields, recent trades, dealer estimates, valuation models, benchmarking of like securities, sector groupings, and/or matrix pricing. The Bank establishes a price for each of its investment securities using a formula that is based upon the number of prices received.

The computed prices are tested for reasonableness using specified tolerance thresholds. Prices within the established thresholds are generally accepted unless strong evidence suggests that using the formula-driven price would not be appropriate. Preliminary estimated fair values that are outside the tolerance thresholds, or that management believes may not be appropriate based on all available information (including those limited instances in which only one price is received), are subject to further analysis including, but not limited to, a comparison with the prices for similar securities and/or to nonbinding dealer estimates or use of an internal model that is deemed most appropriate after consideration of all relevant facts and circumstances that a market participant would consider. As of September 30, 2011, vendor prices were received for substantially all of the FHLBanks' investment securities and all of those prices fell within the specified thresholds. The relative proximity of the prices received supports the Bank's conclusion that the final computed prices are reasonable estimates of fair value. Based on the current lack of significant market activity for private-label residential MBS, the nonrecurring fair-value measurements for such securities as of September 30, 2011, fell within Level 3 of the fair-value hierarchy. 

REO. For the Bank's REO the fair value is derived from third party valuations of the property.

Derivative Assets/Liabilities. Fair value of derivatives is generally determined using discounted cash-flow analysis (the income approach) and comparisons with similar instruments (the market approach). The discounted cash-flow model uses market-observable inputs (inputs that are actively quoted and can be validated to external sources). Inputs by class of derivative are as follows:

Interest-rate-exchange agreements:

• LIBOR swap curve; and

• Market-based expectations of future interest-rate volatility implied from current market prices for similar options for agreements containing options.

46

Mortgage delivery commitments:

• MBS TBA price. Market-based prices of TBAs are determined by coupon class and expected term until settlement.

The Bank generally uses a midmarket pricing convention as a practical expedient for fair-value measurements within a bid-ask spread. Because these estimates are made at a specific point in time, they are susceptible to material near-term changes.

Note 18 — Commitments and Contingencies

Joint and Several Liability. COs are backed by the financial resources of the FHLBanks. The joint and several liability regulation of the Finance Agency authorizes the Finance Agency to require any FHLBank to repay all or a portion of the principal and interest on COs for which another FHLBank is the primary obligor. No FHLBank has ever been asked or required to repay the principal or interest on any CO on behalf of another FHLBank. The Bank evaluates the financial condition of the other FHLBanks primarily based on known regulatory actions, publicly available financial information, and individual long-term credit-rating action as of each period-end presented. Based on this evaluation, as of September 30, 2011, and through the filing of this report, the Bank does not believe that it is reasonably likely to be required to repay the principal or interest on any CO on behalf of another FHLBank.

The Bank has considered applicable FASB guidance and determined it is not necessary to recognize a liability for the fair value of the Bank's joint and several liability for all of the COs. The joint and several obligation is mandated by Finance Agency regulations and is not the result of an arms-length transaction among the FHLBanks. The FHLBanks have no control over the amount of the guaranty or the determination of how each FHLBank would perform under the joint and several obligation. Because the FHLBanks are subject to the authority of the Finance Agency as it relates to decisions involving the allocation of the joint and several liability for the FHLBanks' COs, the FHLBanks' joint and several obligation is excluded from the initial recognition and measurement provisions. Accordingly, the Bank has not recognized a liability for its joint and several obligation related to other FHLBanks' COs at September 30, 2011, and December 31, 2010. The par amounts of other FHLBanks' outstanding COs for which the Bank is jointly and severally liable totaled approximately $653.9 billion and $743.0 billion at September 30, 2011, and December 31, 2010, respectively. See Note 12 — Consolidated Obligations for additional information.

Off-Balance-Sheet Commitments

The following table shows the Bank's off-balance-sheet commitments as of September 30, 2011, and December 31, 2010 (dollars in thousands):

__________________________

(1) Excludes commitments to issue standby letters of credit that expire within one year totaling $31.4 million as of September 30, 2011.

(2) Commitments for unused line-of-credit advances are generally for periods of up to 12 months. Since many of these commitments are not expected to be drawn upon, the total commitment amount does not necessarily indicate future

47

liquidity requirements.

(3) The Bank had $215.0 million in unsettled CO bonds which were hedged with associated interest-rate swaps at September 30, 2011. No unsettled CO bonds were hedged with associated interest-rate exchange agreements at December 31, 2010.

Commitments to Extend Credit. Standby letters of credit are executed with members or housing associates for a fee.A standby letter of credit is a financing arrangement between the Bank and a member or housing associate pursuant to which the Bank (for a fee) agrees to fund the associated member's or housing associate's obligation to a third-party beneficiary should that member or housing associate fail to fund such obligation. If the Bank is required to make payment for a beneficiary's draw, the payment amount is converted into a collateralized advance to the member or housing associate. The original terms of these standby letters of credit, including related commitments, range from two months to 20 years, including a final expiration in 2024.

Unearned fees for the value of the guarantees related to standby letters of credit are recorded in other liabilities and totaled $685,000 and $891,000 at September 30, 2011, and December 31, 2010, respectively. Based on management's credit analyses and collateral requirements, the Bank has not deemed it necessary to record any additional liability on these commitments. Commitments are fully collateralized at the time of issuance.

The Bank monitors the creditworthiness of its members and housing associates that have standby letter of credit agreements outstanding based on an evaluation of their financial condition. The Bank reviews available financial data, such as regulatory call reports filed by depository institution members, regulatory financial statements filed with the appropriate state insurance department by insurance company members, audited financial statements of housing associates, SEC filings, and rating-agency reports to ensure that potentially troubled members are identified as soon as possible. In addition, the Bank has access to most members' regulatory examination reports. The Bank analyzes this information on a regular basis.

Standby Bond-Purchase Agreements. The Bank has entered into standby bond-purchase agreements with state housing authorities whereby the Bank, for a fee, agrees to purchase and hold the housing authority’s bonds until the designated remarketing agent can find a suitable investor or the housing authority repurchases the bonds according to a schedule established by the standby agreement. Each standby agreement dictates the specific terms that would require the Bank to purchase the bonds. The standby bond-purchase commitments entered into by the Bank expire between one and three years following the start of the commitment, currently no later than 2013. At September 30, 2011, the Bank had standby bond purchase agreements with one state housing authority. At December 31, 2010, the Bank had standby bond purchase agreements with two state housing authorities. During the nine months ended September 30, 2011, and year ended December 31, 2010, the Bank was not required to purchase any bonds under these agreements.

Commitments to Invest in Mortgage Loans. Commitments to invest in mortgage loans are generally for periods not to exceed 45 business days. Such commitments are recorded as derivatives at their fair values on the statement of condition.

Pledged Collateral. The Bank executes new derivatives with counterparties with long-term ratings of single-A (or equivalent) or better by either S&P or Moody’s, and enters into bilateral-collateral agreements. Derivatives with counterparties rated lower than single-A (or equivalent) are permitted only if they reduce exposure to that counterparty. As of September 30, 2011, and December 31, 2010, the Bank had pledged as collateral securities with a carrying value, including accrued interest, of $759.5 million and $397.2 million, respectively, to counterparties that have credit-risk exposure to the Bank related to derivatives. These amounts pledged as collateral were subject to contractual agreements whereby some counterparties had the right to sell or repledge the collateral.

Legal Proceedings.

The Bank is subject to various other pending legal proceedings arising in the normal course of business. Management does not anticipate that the ultimate liability, if any, arising out of these matters will have a material effect on the Bank’s financial condition, results of operations, or cash flows.

Note 20 — Transactions with Other FHLBanks

The Bank may occasionally enter into transactions with other FHLBanks. These transactions are summarized below.

Overnight Funds. The Bank may borrow or lend unsecured overnight funds from or to other FHLBanks. All such transactions are at current market rates. Interest income and interest expense related to these transactions with other FHLBanks are included within other interest income and interest expense from other borrowings in the statement of operations.

MPF Mortgage Loans. The Bank pays a transaction-services fee to the FHLBank of Chicago for the Bank’s participation in the MPF program. This fee is assessed monthly, and is based upon the amount of MPF loans in which the Bank invested after January 1, 2004, and which remain outstanding on the Bank’s statement of condition. The Bank recorded $285,000 and $262,000 in MPF transaction-services fee expense to the FHLBank of Chicago during the three months ended September 30, 2011 and 2010, respectively, which has been recorded in the statement of operations as other expense. The Bank recorded $843,000 and $786,000 in MPF transaction-services fee expense to the FHLBank of Chicago during the nine months ended September 30, 2011 and 2010, respectively, which has been recorded in the statement of operations as other expense.

Note 21 — Subsequent Events

On October 21, 2011, the board of directors declared a cash dividend at an annualized rate of 0.30 percent based on capital stock balances outstanding during the third quarter of 2011. The dividend, including dividends on mandatorily redeemable capital stock, amounted to $2.9 million and was paid on November 2, 2011.

The Bank cautions that, by their nature, forward-looking statements are subject to a number of risks or uncertainties, including the risk factors set forth in Item 1A — Risk Factors of the 2010 Annual Report and Part II — Item 1A — Risk Factors of this quarterly report, and the risks set forth below. Accordingly, the Bank cautions that actual results could differ materially from those expressed or implied in these forward-looking statements or could impact the extent to which a particular objective, projection, estimate or prediction is realized. As a result, you are cautioned not to place undue reliance on such statements. 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.

Forward-looking statements in this report include, among others, the following:

• the Bank's projections regarding income, retained earnings, and dividend payouts;

• the Bank's projections regarding credit losses on advances, investments in whole mortgages, and mortgage-related securities;

• the Bank's expectations relating to future balance-sheet growth;

• the Bank's targets under the Bank's retained earnings plan; and

• the Bank's expectations regarding the size of its mortgage-loan portfolio, particularly as compared to prior periods.

Actual results may differ from forward-looking statements for many reasons, including, but not limited to:

• changes in interest rates, housing prices, employment rates, and the general economy;

• changes in the size of the residential mortgage market;

• changes in demand for Bank advances and other products resulting from changes in members' deposit flows and credit demands or otherwise;

• the willingness of the Bank's members to do business with the Bank despite the absence of dividend payments from November 2008 until February 2011 and the continuing moratorium on the repurchase of excess capital stock;

• changes in the financial health of the Bank's members;

• insolvencies of the Bank's members;

• increases in borrower defaults on mortgage loans in the housing market;

• deterioration in the credit performance of the Bank's private-label MBS portfolio beyond forecasted assumptions concerning loan default rates, loss severities, and prepayment speeds resulting in the realization of additional other-than-temporary impairment charges;

• deterioration in the credit performance of the Bank’s investments in mortgage loans and increases in loss severities from those investments;

• an increase in advance prepayments as a result of changes in interest rates or other factors;

• the volatility of market prices, rates, and indices that could affect the value of collateral held by the Bank as security for obligations of Bank members and counterparties to interest-rate-exchange agreements and similar agreements;

• political events, including legislative, regulatory, judicial, or other developments that affect the Bank, its members, counterparties, and/or investors in the COs of the FHLBanks;

• competitive forces including, without limitation, other sources of funding available to Bank members, other entities

51

borrowing funds in the capital markets, and the ability to attract and retain skilled employees;

• the pace of technological change and the ability of the Bank to develop and support technology and information systems sufficient to manage the risks of the Bank's business effectively;

• the loss of large members through mergers and similar activities;

• changes in investor demand for COs and/or the terms of interest-rate-exchange-agreements and similar agreements;

• the timing and volume of market activity;

• the volatility of reported results due to changes in the fair value of certain assets and liabilities, including, but not limited to, private-label MBS;

• the ability to introduce new (or adequately adapt current) Bank products and services and successfully manage the risks associated with those products and services, including new types of collateral used to secure advances;

• the availability of derivative financial instruments of the types and in the quantities needed for risk-management purposes from acceptable counterparties;

• the realization of losses arising from litigation filed against the Bank or one or more of the other FHLBanks;

• the realization of losses arising from the Bank's joint and several liability on COs;

• inflation or deflation;

• issues and events across the FHLBank System and in the political arena that may lead to regulatory, judicial, or other developments may affect the marketability of the COs, the Bank's financial obligations with respect to COs, the Bank's ability to access the capital markets, the manner in which the Bank operates, or the organization and structure of the FHLBank System;

• significant business disruptions resulting from natural or other disasters, acts of war or terrorism; and

• the effect of new accounting standards, including the development of supporting systems.

These risk factors are not exhaustive. The Bank operates in a changing economic and regulatory environment, and new risk factors will emerge from time to time. Management cannot predict such new risk factors nor can it assess the impact, if any, of such new risk factors on the business of the Bank or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those implied by any forward-looking statements.

The Management's Discussion and Analysis of Financial Condition and Results of Operations should be read in conjunction with the Bank's interim financial statements and notes, which begin on page 3, and the 2010 Annual Report.

EXECUTIVE SUMMARY

The Bank recognized net income of $50.0 million for the three months ended September 30, 2011, versus $41.3 million for the same period in 2010. Credit losses from the other-than-temporary impairment of investments in private-label MBS totaled $7.2 million for the three months ended September 30, 2011, compared with credit losses of $5.9 million for the comparable period of 2010. Additionally:

• retained earnings increased from $249.2 million at December 31, 2010, to $336.1 million at September 30, 2011;

• accumulated other comprehensive loss related to the noncredit portion of other-than-temporary impairment losses on held-to-maturity securities improved from an accumulated deficit of $621.5 million at December 31, 2010, to an accumulated deficit of $454.7 million at September 30, 2011; and

• the Bank continues to be in compliance with all regulatory capital requirements.

On October 21, 2011, the Bank's board of directors declared a cash dividend that was the equivalent to an annual yield of 0.30 percent.

The Bank continues to face challenges, the foremost of which arise from its investments in private-label MBS and the decline in advances balances. Accordingly, the Bank continues its moratorium on excess stock repurchases and maintains its retained

52

earnings target at $925.0 million.

• Investments in Private-Label MBS. Although the amortized cost of the Bank's total investments in private-label MBS has fallen to $2.1 billion at September 30, 2011, compared with $6.4 billion at September 30, 2007, additional losses from that portfolio are possible. Management has determined that 22 of its private-label MBS, representing an aggregated par value of $370.3 million, incurred additional other-than-temporary impairment credit losses of $7.2 million for the quarter ended September 30, 2011. Given the ongoing deterioration in the performance of many Alt-A mortgage loans originated in the 2005 to 2007 period, which comprise a significant portion of loans backing private-label MBS owned by the Bank, the Bank continued to use updated modeling assumptions to reflect current developments in loan performance and attendant forecasts. Despite some signs of economic recovery observed in recent periods, many of the factors impacting the underlying loans continue to show little if any improvement; such factors include elevated unemployment rates, extremely high levels of foreclosures and troubled real estate loans, projections of further drops in housing prices and slow housing price recovery, and limited financing opportunities for many borrowers, especially those whose houses are now worth less than the balance of their mortgages. Further, recent foreclosure moratoriums by several major mortgage servicers may result in loss severities beyond current expectations should the impact of such moratoria be prolonged, potentially resulting in disruption to cash flows from impacted securities and further depression in real estate prices. Additionally, certain updates to the Bank's loss projection model resulted in a change in the timing of projected borrower defaults that we believe better reflects longer foreclosure and property liquidation timelines. As a result, borrower defaults and collateral losses are projected to occur over a longer time period compared to prior projections. The change in the timing of projected borrower defaults and collateral losses also had an impact on the amount and timing of security-level projected losses that is unique to the waterfall structure of each security. In general, these timing changes caused credit charges to be somewhat lower than they would have been without the timing effects.

• Decline in Advances Balances. The outstanding par balance of advances to members declined from $27.4 billion at December 31, 2010, to $24.4 billion at September 30, 2011. This reduction is primarily attributable to the high levels of deposits that members continue to experience relative to historical norms. Deposits serve as liquidity alternatives to advances. This reduction in demand for advances has occurred across the Bank's membership including among the Bank's five largest borrowers of advances, as discussed under — Financial Condition — Advances. The Bank expects demand for advances to continue to trend downward so long as deposit levels at members remain high in the absence of any other changes that would influence demand for advances.

This trend in advances balances is illustrated by the following graph of quarter-end total advances balances:

Other significant trends and developments include the following:

• Strong Net Interest Margin. The Bank continues to achieve a favorable net interest margin, which mitigates to some extent the lower demand for advances. Net interest margin for the quarter ended September 30, 2011, was 0.63 percent, a 15 basis point increase from net interest margin for the quarter ended September 30, 2010. Prepayment-fee income was an important contributor to net interest margin for the periods ended September 30, 2010 as demonstrated

53

by the tables captioned “Net Interest Spread and Margin without Prepayment-Fee Income” under — Results of Operations — Rate and Volume Analysis. The increase in net interest margin was achieved despite the historically low-interest-rate environment due in part to a relatively steeper interest-rate yield curve and continued demand for the FHLBank System's CO debt in the face of shrinking supply. As interest rates remained at historically low levels, the Bank also continued to benefit from having refinanced callable debt used to fund its fixed-rate residential mortgage assets in prior periods as interest rates fell. During the 12 months ended September 30, 2011, the Bank exercised redemption options on $3.7 billion of callable bonds that were not swapped to a synthetic floating rate coupon. Of this amount, $1.6 billion was concentrated during the three months ended September 30, 2011. Other factors behind the improvement in net interest margin include an increase in yields on certain previously other-than-temporarily impaired private-label MBS for which a significant improvement in cash flows has been projected.

• Credit Rating Agency Developments. On August 8, 2011, S&P downgraded the Bank's long-term credit rating to AA+ with a negative outlook based on its downgrade of the long-term sovereign credit rating of the United States from AAA to AA+ with a negative outlook. This and other credit rating agency developments have occurred during the period covered by this report and have possible adverse implications for the Bank as discussed more fully under — Credit Rating Agency Developments.

• Federal Reserve Board's (the Federal Reserve's) Measures Intended to Maintain Low Interest Rates. The Federal Reserve has taken several measures intended to maintain low interest rates, including an announcement that it expects to maintain short-term interest rates near zero until mid-2013 as well as to implement “Operation Twist” pursuant to which the Federal Reserve intends to drive down longer-term interest rates by purchasing longer-dated assets and selling shorter-dated assets. These measures as well as other systemic events, such as the European sovereign debt crisis, could result in a prolonged low-interest rate environment. A prolonged low-interest rate environment could adversely impact the Bank in various ways, including through lower market yields on investments, including investments in loans, and faster prepayments on Bank investments with associated reinvestment risk. The Bank's investment income and, in turn, the Bank's financial condition and results of operations, could be adversely impacted to the extent that the foregoing, or similar, risks are realized. However, the Bank could also experience increased demand for advances if a prolonged low-interest environment results in increased business activity with associated demand for loans from Bank members that choose to fund such loans with advances. Increased demand for advances would tend to increase net interest income and could offset some of the adverse impact of a prolonged low-interest rate environment on investment income. Accordingly, management is not able to predict the impact of the Federal Reserve's measures to maintain low interest rates.

• Satisfaction of the REFCorp Obligation. On August 5, 2011, the Finance Agency certified that the FHLBanks had fully satisfied their obligation to make payments to REFCorp with their payment based on their results as of June 30, 2011. Until this time, the Bank had been obligated to make payments to REFCorp in the amount of 20 percent of net earnings after AHP expenses. The REFCorp obligation is more fully described in the 2010 Annual Report under Item 1 — Business — Assessments.

• Net Income Allocation Requirements under the Joint Capital Enhancement Agreement and Related Amendments to the Bank's Capital Plan. The FHLBanks have entered into a Capital Agreement as part of a voluntary capital initiative intended to build greater safety and soundness in the FHLBank System. Due to the satisfaction of the REFCorp obligation, the Capital Agreement, among other things, obligates each FHLBank to allocate an amount at least equal to 20 percent of its quarterly net income to a restricted retained earnings account beginning with the quarter ended September 30, 2011. On August 5, 2011, the Bank provided its members notice of certain amendments to its capital plan that became effective on September 5, 2011, and are intended to conform the Bank's capital plan with the Capital Agreement. The capital plan amendments and the Capital Agreement are more fully described under — Liquidity and Capital Resources — Capital Plan Amendments and Restricted Retained Earnings.

• Regulatory Developments under the Dodd-Frank Wall Street Reform and Consumer Protection Act (the Dodd-Frank Act). Various regulations have been proposed to implement the Dodd-Frank Act that are likely to impact the Bank's business operations, funding costs, obligations, and/or the environment in which the Bank carries out its housing-finance mission. For example, the Bank expects regulations proposed by the U.S. Commodity Futures Trading Commission (the CFTC) under the Dodd-Frank Act, including such regulations proposed during the period covered by this report, to impact its derivatives activities and result in incremental costs for the Bank in complying with those regulations. For additional information on the Dodd-Frank Act's possible impact on the Bank, see — Legislative and Regulatory Developments.

RESULTS OF OPERATIONS

Third Quarter of 2011 Compared with Third Quarter of 2010

For the three months ended September 30, 2011 and 2010, the Bank recognized net income of $50.0 million and $41.3 million, respectively. This $8.6 millionincrease was driven by an increase of $5.1 million in net interest income, a $9.4 million decrease in assessments due to the fulfillment of the REFCorp obligation, and a $5.3 millionincrease in net unrealized gains on trading securities. These increases to net income were partially offset by an $8.4 million increase in net losses on derivatives and hedging activities, a $2.0 million increase in other expense, and a $1.3 millionincrease in other-than-temporary impairment losses of certain private-label MBS.

Nine Months Ended September 30, 2011, Compared with Nine Months Ended September 30, 2010

For the nine months ended September 30, 2011 and 2010, the Bank recognized net income of $94.9 million and $83.0 million, respectively. This $11.9 millionincrease was driven by an increase of $5.9 million in net interest income, a $12.8 million realized net gain from the sale of available-for-sale securities, an $8.3 million decrease in assessments, a $2.9 million reduction in net losses on derivatives and hedging activities, and a $2.3 million reduction to the provision for credit losses. These gains were partially offset by an increase of $14.4 million in other-than-temporary impairment losses of certain private-label MBS, and a $6.3 million increase in other expenses.

Net Interest Income

Third Quarter of 2011 Compared with Third Quarter of 2010

57

Net interest income for the three months ended September 30, 2011, was $80.4 million, compared with $75.3 million for the same period in 2010. Important to this increase was a $4.5 millionincrease in prepayment fee income, which led to an increase of 8 basis points in the yield on interest-earning assets to 1.49 percent. In addition, the average cost of interest-bearing liabilities decreased 6 basis points to 0.94 percent. Partially offsetting the increase in net interest spread was a decrease in average earning assets, which declined by $11.8 billion from $62.6 billion for the three months ended September 30, 2010, to $50.9 billion for the three months ended September 30, 2011.

Net interest margin for the three months ended September 30, 2011, in comparison with the same period in 2010, increased to 63 basis points from 48 basis points, and net interest spread increased to 55 basis points from 41 basis points for the same period in 2010. Factors underlying the increase in net interest margin are discussed under — Executive Summary.

Nine Months Ended September 30, 2011, Compared with Nine Months Ended September 30, 2010

Net interest income for the nine months ended September 30, 2011, was $224.0 million, compared with $218.1 million for the same period in 2010. This increase was primarily attributable to the $14.2 millionincrease in prepayment fee income, which led to an increase of 8 basis points in the yield on interest earning assets to 1.45 percent. In addition, the average cost of interest-bearing liabilities decreased 1 basis point to 0.97 percent.

Net interest margin for the nine months ended September 30, 2011, in comparison with the same period in 2010, increased to 56 basis points from 46 basis points, and net interest spread increased to 48 basis points from 39 basis points for the same period in 2010. Partially offsetting the increase in net interest spread was a decrease in average earning assets, which declined by $10.6 billion from $63.9 billion for the nine months ended September 30, 2010, to $53.3 billion for the nine months ended September 30, 2011.

The following table presents major categories of average balances, related interest income/expense, and average yields for interest-earning assets and interest-bearing liabilities. The primary source of earnings for the Bank is net interest income, which is the interest earned on advances, mortgage loans, and investments less interest paid on COs, deposits, and other borrowings. Net interest spread is the difference between the yields on interest-earning assets and interest-bearing liabilities. Net interest margin is expressed as the percentage of net interest income to average earning assets.

Rate and Volume Analysis

Changes in both average balances (volume) and interest rates influence changes in net interest income and net interest margin. The following table summarizes changes in interest income and interest expense for the three and nine months endedSeptember 30, 2011 and 2010. Changes in interest income and interest expense that are not identifiable as either volume-related or rate-related, but rather equally attributable to both volume and rate changes, have been allocated to the volume and rate categories based upon the proportion of the absolute value of the volume and rate changes.

The average balance of total advances decreased $7.3 billion, or 22.7 percent, for the three months ended September 30, 2011, compared with the same period in 2010. The trend of decreasing member demand for advances is discussed under — Executive Summary. The following table summarizes average balances of advances outstanding during the nine months ending September 30, 2011 and 2010, by product type.

Total average advances	$	25,795,091	$	34,639,855

Putable advances that are classified as fixed-rate advances in the table above are typically hedged with interest-rate-exchange agreements in which a short-term rate is received, typically three-month LIBOR. In addition, approximately 25.5 percent of average long-term fixed-rate advances were similarly hedged with interest-rate swaps. Therefore, a significant portion of the Bank's advances, including overnight advances, short-term fixed-rate advances, fixed-rate putable advances, certain fixed-rate bullet advances, and variable-rate advances, either earn a short-term interest rate or are swapped to a short-term index, resulting in yields that closely follow short-term market interest-rate trends. The average balance of these advances totaled $15.1 billion for the nine months ended September 30, 2011, representing 60.1 percent of the total average balance of advances outstanding during the nine months ended September 30, 2011. The average balance of these advances totaled $24.9 billion for the nine months ended September 30, 2010, representing 73.5 percent of the total average balance of advances outstanding during the nine months ended September 30, 2010.

Prepayment fees related to advances and investment securities are included in net interest income. Prepayment fees make the Bank financially indifferent to the prepayment of advances or investments. For the nine months ended September 30, 2011 and 2010, net prepayment fees on advances were $20.4 million and $7.5 million, respectively. For the nine months ended September 30, 2011 and 2010, prepayment fees on investments were $1.4 million and $34,000, respectively. Prepayment-fee income is unpredictable and inconsistent from period to period, occurring only when advances and investments are prepaid prior to the scheduled maturity or repricing dates.

Because prepayment-fee income recognized during these periods does not necessarily represent a trend that will continue in future periods, and due to the fact that prepayment-fee income represents a one-time fee recognized in the period in which the corresponding advance or investment security is prepaid, the Bank believes it is important to review the results of net interest spread and net interest margin excluding the impact of prepayment-fee income. These results are presented in the following table.

(1) Yields are annualized.

Average short-term money-market investments, consisting of interest-bearing deposits, securities purchased under agreements to resell, and federal funds sold, decreased $1.7 billion, or 18.6 percent, for the nine months ended September 30, 2011, compared with the same period in 2010. The yield earned on short-term money-market investments is highly correlated to short-term market interest rates. These investments are used for liquidity management and to manage the Bank's leverage ratio in response to fluctuations in other asset balances. For the nine months ended September 30, 2011, federal funds sold and securities purchased under agreements to resell decreased $462.2 million and $1.2 billion, respectively, in comparison to the nine months ended September 30, 2010.

Average investment-securities balances increased $167.5 million or 1.0 percent for the nine months ended September 30, 2011, compared with the same period in 2010. This increase was primarily due to an increase of $276.7 million in average certificates of deposit along with a $165.0 million increase in agency and supranational banks. These increases were offset by a $199.3 million decrease in corporate bonds and a $65.8 million decrease in MBS.

Average mortgage loans for the nine months ended September 30, 2011, were $204.6 million lower than the average balance for the nine months ended September 30, 2010, representing a decrease of 6.1 percent.

Average CO balances decreased $10.7 billion, or 18.2 percent, for the nine months ended September 30, 2011, compared with the same period in 2010, resulting from the Bank's reduced funding needs due to the decline in member demand for advances, as discussed under — Executive Summary. This overall decline consisted of a decrease of $7.6 billion in CO discount notes and a decrease of $3.1 billion in CO bonds.

The average balance of term CO discount notes decreased $5.2 billion and overnight CO discount notes decreased $2.4 billion for the nine months ended September 30, 2011, in comparison to the same period in 2010. Average balances of CO bonds decreased $3.1 billion compared to the same period in 2010. The average balance of CO discount notes represented approximately 27.9 percent of total average COs during the nine months ended September 30, 2011, as compared with 35.7 percent of total average COs during the nine months ended September 30, 2010. The average balance of bonds represented 72.1 percent and 64.3 percent of total average COs outstanding during the nine months ended September 30, 2011 and 2010, respectively. The relative increase in the proportion of CO bonds as compared to total COs is due to the net decline in short-term assets, including short-term advances and money-market investments, and to the increase in long-term assets, including U.S. agency debentures.

Impact of Derivative and Hedging Activity

Net interest income includes interest accrued on interest-rate-exchange agreements that are associated with advances,

64

investments, deposits, and debt instruments that qualify for hedge accounting. The Bank generally uses derivative instruments that qualify for hedge accounting as an interest-rate-risk-management tool. These derivatives serve to stabilize net interest income and net interest margin when interest rates fluctuate. Accordingly, the impact of derivatives on net interest income and net interest margin should be viewed in the overall context of the Bank's risk-management strategy. The following tables show the net effect of derivatives and hedging activities on net interest income, net gains (losses) on derivatives and hedging activities, and net unrealized gains on trading securities for the three and nine months endedSeptember 30, 2011 and 2010 (dollars in thousands).

Net interest margin for the three months ended September 30, 2011 and 2010, was 0.63 percent and 0.48 percent, respectively. If derivative instruments had not been used as hedges to mitigate the impact of interest-rate fluctuations, net interest margin would have been 0.95 percent and 0.84 percent, respectively.

Net interest margin for the nine months ended September 30, 2011 and 2010, was 0.56 percent and 0.46 percent, respectively. If derivative instruments had not been used as hedges to mitigate the impact of interest-rate fluctuations, net interest margin would have been 0.89 percent and 0.82 percent, respectively.

Interest paid and received on interest-rate-exchange agreements that are used by the Bank in its asset and liability management, but which do not meet hedge-accounting requirements (economic hedges), are classified as net loss on derivatives and hedging activities in other income. As shown under Other Income (Loss) and Operating Expenses below, interest accruals on derivatives classified as economic hedges totaled a net expense of $2.1 million and $2.5 million, respectively, for the three months ended September 30, 2011 and 2010. For both the nine months ended September 30, 2011 and 2010, interest accruals on derivatives classified as economic hedges totaled a net expense of $7.0 million.

Other Income (Loss) and Operating Expenses

The following table presents a summary of other income (loss) for the three and nine months ended September 30, 2011 and 2010. Additionally, detail on the components of net gains (losses) on derivatives and hedging activities is provided, indicating the source of these gains and losses by type of hedging relationship and hedge accounting treatment.

As noted in the Other Income (Loss) table above, accounting for derivatives and hedged items introduces the potential for considerable timing differences between income recognition from assets or liabilities and income effects of hedging instruments entered into to mitigate interest-rate risk and cash-flow activity.

For the securities on which the Bank recognized other-than-temporary impairment during 2011, the average credit enhancement was not sufficient to cover projected expected credit losses. The average credit enhancement at September 30, 2011, was approximately 15.2 percent and the expected average collateral loss was approximately 29.8 percent. Accordingly, the Bank recorded an other-than-temporary impairment related to a credit loss of $7.2 million during the third quarter of 2011.

The following table displays the Bank's held-to-maturity securities for which other-than-temporary impairment was recognized in the three and nine months ending September 30, 2011 and 2010, based on whether the security is newly impaired or previously impaired (dollars in thousands).

Changes in the fair value of trading securities are recorded in other loss. The Bank recorded net unrealized gains on trading securities of $13.6 million and $8.4 million for the three months ended September 30, 2011 and 2010, respectively. Changes in the fair value of the associated economic hedges amounted to net losses of $16.0 million and $8.4 million for the three months ended September 30, 2011 and 2010, respectively. Also included in other loss are interest accruals on these economic hedges, which resulted in net losses of $1.9 and $1.8 million for the three months ended September 30, 2011 and 2010, respectively.

For the nine months ended September 30, 2011 and 2010, the Bank recorded net unrealized gains on trading securities of $17.6 million and $18.8 million, respectively. Changes in the fair value of the associated economic hedges amounted to net losses of $18.8 million and $24.1 million for the nine months ended September 30, 2011 and 2010, respectively. Also included in other loss are interest accruals on these economic hedges, which resulted in a net loss of $5.8 million and $5.0 million for the nine months ended September 30, 2011 and 2010, respectively.

(1)Weighted-average rates are based on the contract rate of each advance without taking into consideration the effects of interest-rate-exchange agreements that may be used by the Bank as a hedging instrument.

(2) In April 2011, First Niagara Financial Group Inc., a nonmember, acquired NewAlliance Bancshares, Inc. (parent of former member New Alliance Bank). Nonmembers, excluding housing associates, are ineligible to borrow from the Bank. Accordingly, the acquisition of NewAlliance Bank by First Niagara Financial Group Inc. could adversely impact the Bank's advances interest income.

As with other members, the top five advance-borrowing institutions have reduced their demand for advances since December 31, 2010. At September 30, 2011, the par value of advances for these institutions aggregated to $8.6 billion falling from $10.2 billion at December 31, 2010.

The Bank prices advances based on the marginal cost of funding with a similar maturity profile, as well as market rates for comparable funding alternatives. In accordance with regulations, the Bank prices its advance products in a consistent and nondiscriminatory manner to all members. However, the Bank may price its products on a differential basis, which is based on the creditworthiness of the member, volume, or other reasonable criteria applied consistently to all members. Differences in the weighted-average rates of advances outstanding to the five largest advance-borrowing institutions noted in the table above result from several factors, including the disbursement date of the advances, the product type selected, and the term to maturity.

Advances Credit Risk

The Bank endeavors to minimize credit risk on advances by monitoring the financial condition of its borrowing entities and by holding sufficient collateral to protect itself from losses. All pledged collateral is subject to haircuts assigned by the Bank based on the Bank's opinion of the risk that such collateral presents. The Bank is prohibited by Section 10(a) of the FHLBank Act from making advances without sufficient collateral to secure the advance. The Bank has never experienced a credit loss on an advance.

The Bank closely monitors the financial condition of all members and housing associates by reviewing available financial data, such as regulatory call reports filed by depository institution members, regulatory financial statements filed with the appropriate state insurance department by insurance company members, audited financial statements of housing associates, SEC filings, and rating-agency reports to ensure that potentially troubled members are identified as soon as possible. In addition, the Bank has access to most members' regulatory examination reports. The Bank analyzes this information on a regular basis.

The Bank's membership continues to be challenged by the current weak economic conditions, although there have been some measures of improvement. Aggregate nonperforming assets for depository institution members declined from 1.94 percent of total assets as of December 31, 2010, to 1.23 percent of assets as of June 30, 2011. The aggregate ratio of tangible capital to assets among the membership decreased from 10.25 percent as of December 31, 2010, to 8.83 percent as of June 30, 2011. June 30, 2011, is the most recent date of the Bank's data on its membership for purposes of this report. The decrease in the ratio of tangible capital to assets among the membership resulted almost entirely from the addition of one large institution to the Bank's membership during the quarter ended June 30, 2011, and does not reflect a deterioration in the Bank's membership. Through the ten-month period ending October 31, 2011, there were no member failures. All extensions of credit by the Bank to members are secured by eligible collateral as noted herein. However, if a member were to default, and the value of the collateral pledged by the member declined to a point such that the Bank was unable to realize sufficient value from the pledged collateral to cover the member's obligations and the Bank were unable to obtain additional collateral to make up for the reduction in value of such collateral, the Bank could incur losses. A default by a member with significant obligations to the Bank could result in significant financial losses, which would adversely impact the Bank's results of operations and financial condition.

The Bank assigns each borrower into one of three collateral categories: Category 1 (blanket) collateral status, Category 2 (listing) collateral status, or Category 3 (delivery) collateral status.

• The Bank assigns members that it has determined are in good financial condition to Category 1 (blanket) status.

• The Bank assigns members that demonstrate characteristics that evidence potential weakness in their financial condition to Category 2 (listing) collateral status. The Bank may also assign members with a high level of borrowings as a percentage of their assets to Category 2 (listing) collateral status regardless of their financial condition.

• The Bank assigns members that it has determined are financially weak to Category 3 (delivery) collateral status. The Bank also assigns all insurance company members that have an NRSRO long-term debt rating lower than BBB- or its equivalent, insurance company members that do not have an NRSRO long-term debt rating, and all housing associates to Category 3 (delivery) collateral status.

For additional information on the Bank's classification of its borrowers, see the 2010 Annual Report under Item 7 — Management's Discussion and Analysis of Financial Condition and Results of Operations — Financial Condition — Advances Credit Risk.

Advances outstanding to borrowers in Category 1 (blanket) status at September 30, 2011, totaled $15.6 billion. For these advances, the Bank had access to collateral through security agreements, where the borrower agrees to hold such collateral for the benefit of the Bank, totaling $44.2 billion as of September 30, 2011. Of this total, $13.1 billion of securities have been delivered to the Bank or to an approved third-party custodian, an additional $1.8 billion of securities are held by borrowers' securities corporations, and $6.5 billion of residential mortgage loans have been pledged by borrowers' real-estate-investment trusts.

The following table provides information regarding advances outstanding with the Bank's borrowers in Category 1 (blanket), Category 2 (listing) and Category 3 (delivery) status at September 30, 2011, along with their corresponding collateral balances.

Advances Outstanding by Borrower Collateral Status As of September 30, 2011 (dollars in thousands)

Based upon the method by which borrowers pledge collateral to the Bank, the following table shows the total potential lending value of the collateral that borrowers have pledged to the Bank, net of the Bank's collateral valuation discounts as of September 30, 2011.

Collateral by Pledge Type (dollars in thousands)
	Discounted Collateral
Collateral not specifically listed and identified	$	37,852,707
Collateral specifically listed and identified	16,706,356
Collateral delivered to the Bank	22,416,771

Beyond the Bank's practices in taking security interests in collateral, Section 10(e) of the FHLBank Act affords any security interest granted by a federally insured depository institution member or such a member's affiliate to the Bank priority over the claims or rights of any other party, including any receiver, conservator, trustee, or similar entity that has the rights of a lien creditor, unless these claims and rights would be entitled to priority under otherwise applicable law and are held by actual purchasers or by parties that are secured by actual perfected security interests. In this regard, the priority granted to the security interests of the Bank under Section 10(e) does not apply when lending to insurance company members due to the antipreemption provision contained in the McCarran-Ferguson Act in which Congress declared that federal law would not preempt state insurance law unless the federal law expressly regulates the business of insurance. Thus, if state law conflicts with Section 10(e) of the FHLBank Act, the protection afforded by this provision may not be available to the Bank. However, the Bank protects its security interests in the collateral pledged by its borrowers, including insurance company members, by filing UCC financing statements, or by taking possession or control of such collateral, or by taking other appropriate steps. Advances outstanding to insurance companies totaled $800.6 million at September 30, 2011.

The Bank accepts nontraditional and subprime loans that are underwritten in accordance with applicable regulatory guidance as eligible collateral for Bank advances as detailed in the 2010 Annual Report under Item 7 — Management's Discussion and Analysis of Financial Condition and Results of Operations — Financial Condition — Advances Credit Risk. At September 30, 2011, the amount of pledged nontraditional and subprime loan collateral was 9 percent of total member borrowing capacity compared with 8 percent of total member borrowing capacity at December 31, 2010.

Based upon the collateral held as security on advances, the Bank's collateral practices and policies, the Bank's prior repayment history, and the protections provided by Section 10(e) of the FHLBank Act, the Bank does not believe that an allowance for losses on advances is necessary at this time.

For additional information on the Bank's collateral policies and practices, See Item 7 — Management’s Discussion and

Investments

At September 30, 2011, investment securities and short-term money-market instruments totaled $19.9 billion, compared with $27.1 billion at December 31, 2010. This decrease reflects management's intent to maintain its investments at a level approximately equal to or less than 50 percent of total assets.

Investment securities declined$6.3 billion to $13.0 billion at September 30, 2011, compared with $19.4 billion at December 31, 2010. The decline is due to the $5.3 billion decrease in certificates of deposits as well as the sale of $1.8 billion of non-MBS available-for-sale securities in the first nine months of 2011, contributing to a $726.5 million decrease in non-MBS GSE securities and a $608.3 million decrease in corporate bonds.

Short-term money-market investments totaled $6.9 billion at September 30, 2011, compared with $7.8 billion at December 31, 2010. This $879.9 million net decrease resulted from a $1.3 billionincrease in securities purchased under agreements to resell and a $2.2 billiondecrease in federal funds sold.

Under the Bank's regulatory authority to purchase MBS, additional investments in MBS, ABS, and certain securities issued by the Small Business Administration (SBA) are prohibited if the Bank's investments in such securities exceed 300 percent of capital. Capital for this calculation is defined as capital stock, mandatorily redeemable capital stock, and retained earnings. At September 30, 2011, and December 31, 2010, the Bank's MBS, ABS and SBA holdings represented 220 percent and 210 percent of capital, respectively.

The Bank's MBS investment portfolio consists of the following categories of securities as of September 30, 2011, and December 31, 2010. The percentages in the table below are based on carrying value.

Mortgage-Backed Securities
	September 30, 2011		December 31, 2010
Residential MBS - U.S. government-guaranteed and GSE	55.8	%	56.5	%
Commercial MBS - U.S. government-guaranteed and GSE	25.4		21.3
Private-label residential MBS	18.4		21.0
ABS backed by home-equity loans	0.3		0.3
Private-label commercial MBS	0.1		0.9
Total MBS	100.0	%	100.0	%

See Item 1 — Notes to the Financial Statements — Note 3 — Trading Securities, Note 4 — Available-for-Sale Securities, Note 5 — Held-to-Maturity Securities, and Note 6 — Other-Than-Temporary Impairment for additional information on the Bank's investment securities.

Investments Credit Risk. The Bank is subject to credit risk on unsecured investments consisting primarily of money-market instruments issued by high-quality counterparties and debentures issued or guaranteed by U.S. agencies, the FDIC under the FDIC's Temporary Liquidity Guarantee Program, U.S government-owned corporations, GSEs, and supranationals. The Bank places short-term funds with large, high-quality financial institutions with long-term credit ratings no lower than single-A (or its equivalent rating) on an unsecured basis; currently all such placements expire within 35 days. The Bank has counterparty exposure on its investments in the form of short-dated unsecured money market transactions and short-dated secured reverse repurchase agreements. Management actively monitors these exposures and the credit quality of its counterparties, including assessments of each counterparty's financial performance, capital adequacy, and sovereign support as well as related market signals. The Bank intends to reduce or suspend credit limits and/or seek to reduce existing exposures as a result of these monitoring activities. As an example, during the third quarter of 2011, the Bank has reduced or restricted trading with certain European counterparties based on the European sovereign debt crisis. At September 30, 2011, the Bank's unsecured credit exposure, including accrued interest related to money-market instruments and debentures, was $7.6 billion to 16 counterparties and issuers, of which $3.4 billion was for federal funds sold, and $4.2 billion was for debentures. The following issuers/counterparties individually accounted for greater than 10 percent of total unsecured credit exposure as of September 30, 2011:

74

Issuers / Counterparties with Total Unsecured Credit Greater Than 10 Percent As of September 30, 2011
Issuer / counterparty	Percent
Fannie Mae	27.2	%
Barclays Bank PLC	13.1
Freddie Mac	10.6

The Bank also is invested in and is subject to secured credit risk related to MBS, ABS, and HFA obligations that are directly or indirectly supported by underlying mortgage loans. Investments in MBS and ABS must be rated triple-A (or its equivalent) at the time of purchase. HFA bonds must carry a credit rating of double-A (or its equivalent rating) or higher as of the date of purchase.

Credit ratings on these investments are provided in the following table.

The following table presents a summary of the average projected values over the remaining lives of the securities for the significant inputs relating to the Bank's private-label MBS during the quarter ended September 30, 2011, as well as related current credit enhancement. Credit enhancement is defined as the percentage of subordinated tranches and over-collateralization, if any, in a security structure that will generally absorb losses before the Bank will experience a loss on the security. The calculated averages represent the dollar-weighted averages of all the private-label residential MBS and home equity loan investments in each category shown, regardless of whether or not the securities have incurred an other-than-temporary credit loss (dollars in thousands).

(1)The Bank's commercial private-label MBS with a par value of $10.6 million and a private-label residential MBS with a par value of $3.5 million that is backed by the Federal Housing Administration and the Department of Veteran Affairs loans

76

were not included in this table.

(2) Securities are classified in the table above based upon the current performance characteristics of the underlying pool and therefore the manner in which the collateral pool group backing the security has been modeled (as prime, Alt-A, or subprime), rather than the classification of the security at the time of issuance.

The Bank classifies private-label residential and commercial MBS and ABS backed by home equity loans as prime, Alt-A, or subprime based on the originator's classification at the time of origination or based on the classification by an NRSRO upon issuance of the MBS. In some instances, the NRSROs may have changed their classification subsequent to origination which would not necessarily be reflected in the following tables.

Of the Bank's $9.6 billion in par value of MBS and ABS investments at September 30, 2011, $2.6 billion in par value are private-label MBS. Of this amount, $2.3 billion in par value are securities backed primarily by Alt-A loans, while $339.6 million in par value are backed primarily by prime loans. Only $28.5 million in par value of these investments are backed primarily by subprime mortgages. While there is no universally accepted definition for prime and Alt-A underwriting standards, in general, prime underwriting implies a borrower without a history of delinquent payments as well as documented income and a loan amount that is at or less than 80 percent of the market value of the house, while Alt-A underwriting implies a prime borrower with limited income documentation and/or a loan-to-value ratio of higher than 80 percent. While the Bank generally follows the collateral type definitions provided by S&P, it does review the credit performance of the underlying collateral, and revises the classification where appropriate, an approach that is likewise incorporated into the modeling assumptions provided by the FHLBank System's OTTI Governance Committee. For additional information on the OTTI Governance Committee, see the 2010 Annual Report under Item 7 — Management's Discussion and Analysis of Financial Condition and Results of Operations — Critical Accounting Estimates. The third-party collateral loan performance platform used by the FHLBank of San Francisco, with whom the Bank has contracted to perform these analyses, assesses eight bonds owned by the Bank, holding $81.8 million in par value as of September 30, 2011, to have collateral that is Alt-A in nature, while that same collateral is classified as prime by S&P. Accordingly, these bonds have been modeled using the same credit assumptions applied to Alt-A collateral. Three of these bonds, with a total par value of $54.1 million as of September 30, 2011, were deemed to be other-than-temporarily impaired as of September 30, 2011. These bonds are reported as prime in the various tables below in this section. In addition, one bond classified as Alt-A collateral by S&P, of which the Bank held $4.7 million in par value as of September 30, 2011, is classified and modeled as prime by the third-party modeling software. However this bond is reported as Alt-A in the various tables below in this section in accordance with S&P's classification. See — Critical Accounting Estimates for information on the Bank's key inputs, assumptions, and modeling employed by the Bank in its other-than-temporary impairment assessments.

 (1) The determination of fixed or variable rate is based upon the contractual coupon type of the security.

The following tables provide additional information related to the Bank's investments in MBS issued by private trusts and ABS backed by home-equity loans, indicating whether the underlying mortgage collateral is considered to be prime, Alt-A, or subprime at the time of issuance. Additionally, the amounts outstanding as of September 30, 2011, are stratified by year of issuance of the security. The tables also set forth the credit ratings and summary credit enhancements associated with the Bank's

77

private-label MBS and ABS, stratified by collateral type and vintage. Average current credit enhancements as of September 30, 2011, reflect the percentage of subordinated class outstanding balances as of September 30, 2011, to the Bank's senior class outstanding balances as of September 30, 2011, weighted by the par value of the Bank's respective senior class securities, and shown by underlying loan collateral type and issuance vintage. Average current credit enhancements as of September 30, 2011, are indicative of the ability of subordinated classes to absorb loan collateral lost principal and interest shortfall before senior classes are impacted. The average current credit enhancements do not fully reflect the Bank's credit protection in its private-label MBS holdings as prioritization in the timing of receipt of cash flows and credit event triggers accelerate the return of the Bank's investment before losses can no longer be absorbed by subordinate classes.

The geographic areas represented in the table above have experienced mortgage loan default rates and home-price depreciation rates that are significantly higher than national averages.

Since 2008, actual and projected delinquency, foreclosure, and loss rates for prime, subprime, and Alt-A mortgages have increased significantly nationwide. While trends have improved in some of these actual measures and their projected assumptions, they remain elevated as of the date of this report. In addition, home prices are severely depressed in many areas and nationwide unemployment rates are high, increasing the likelihood and magnitude of potential losses to lenders on troubled and/or foreclosed real estate. The widespread impact of these trends has led to the recognition of significant losses by financial institutions, including commercial banks, investment banks, and financial guaranty providers. Actual and expected credit losses on these securities together with uncertainty as to the degree, direction, and duration of these loss trends has led to the reduction in the market values of securities backed by residential mortgages, and has elevated the potential for additional credit losses due to the other-than-temporary impairment of some of these securities. Nonetheless, the average prices of these securities in the Bank's portfolio have recovered somewhat from their lows as increased investor appetite for higher yields coupled with renewed leverage and limited supply have combined to narrow mortgage yield spreads compared to U.S. Treasury obligations.

The following graph demonstrates how average prices changed with respect to various asset classes in the Bank's MBS portfolio during the 12 months ended September 30, 2011:

Insured Investments

Certain private-label MBS owned by the Bank are insured by monoline insurers, which guarantee the timely payment of principal and interest on such MBS if such payments cannot be satisfied from the cash flows of the underlying mortgage pool.

83

The assessment for other-than-temporary impairment of the MBS protected by such third-party insurance is described in Item 1 — Notes to the Financial Statements — Note 6 — Other-Than-Temporary Impairment.

The following table provides the credit ratings of the third-party insurers.

Standby Bond-Purchase Agreements. The Bank has entered into standby bond-purchase agreements with one state HFA whereby the Bank, for a fee, agrees to purchase and hold the HFA's unremarketed bonds until the designated remarketing agent can find a new investor or the state HFA repurchases the bonds in accordance with a schedule established by the agreement. Each agreement contains termination provisions in the event of a rating downgrade of the subject bond. Standby bond purchase commitments totaled $245.1 million at September 30, 2011, to this HFA. All of the bonds underlying the commitments to this HFA maintain standalone ratings of triple-A from two rating agencies, even though some are backed by Ambac Assurance Corporation, which itself has been downgraded below triple-A and has filed a petition for bankruptcy.

Mortgage Loans

The outstanding principal amount of the Bank's mortgage loan investment portfolio remained relatively stable through the quarter ended September 30, 2011. Interest in the MPF program continued to grow among prospective participating financial institutions as such institutions sought alternatives to Fannie Mae and Freddie Mac; interest tended to offset the continuing muted borrower demand for mortgage loans in the depressed U.S. housing economy. The Bank has not experienced an increase in prepayment activity on its portfolio of mortgage loans notwithstanding the continuing low interest-rate environment, although an increase in prepayment activity remains possible particularly given the Federal Reserve's measures to maintain low interest rates, as described under — Executive Summary. The Bank expects a slight increase in prepayments for the remainder of the year, although increases could rise, particularly if a new government program is effective in spurring greater prepayments. As of September 30, 2011, the Bank's mortgage loan investment portfolio totaled $3.1 billion, a decrease of $117.2 million from the December 31, 2010, balance of $3.2 billion. References to the Bank's investments in mortgage loans throughout this report include the 100 percent participation interests in mortgage loans purchased under a participation agreement it has with the FHLBank of Chicago. The expiration date of this agreement has been extended to December 31, 2012. As of September 30, 2011, the Bank had $148.6 million in 100 percent participation interests outstanding that had been purchased under this agreement. For additional information on this agreement, see the 2010 Annual Report under Item 1 — Business — MPF Loan Participations with the FHLBank of Chicago.

The FHLBank of Chicago acts as the MPF Provider and provides operational support to the MPF Banks and participating financial institutions and calculates and publishes daily prices, rates, and fees associated with the various MPF products. Since March 26, 2011, the Bank has had the right to adjust its base pricing for MPF products as often as warranted daily for the loans in which it invests and for loans sold pursuant to MPF Xtra. Any such adjusted pricing would then become the Bank's pricing for such loans until such time as the Bank again adjusts its pricing. In connection with the commencement of this right of the Bank to adjust its pricing, the Bank's option to opt out of participation in the MPF program has been eliminated (although the Bank never used this option). However, the Bank believes it can effectively opt out of the program by adjusting pricing should it determine to do so. Alternatively, the Bank has the right to turn off its master commitments at any time for such duration as it selects.

Mortgage Loans Credit Risk. The Bank is subject to credit risk from the mortgage loans in which it invests due to the Bank's exposure to the credit risk of the underlying borrowers and the credit risk of the participating financial institutions when the participating financial institutions retain credit-enhancement and/or servicing obligations. 

Although the Bank's mortgage-loan portfolio includes loans throughout the U.S., concentrations of five percent or greater of the outstanding principal balance of the Bank's conventional mortgage-loan portfolio are shown in the following table:

Allowance for Credit Losses on Mortgage Loans. The allowance for credit losses on mortgage loans was $7.2 million at September 30, 2011, compared with $8.7 million at December 31, 2010. The Bank lowered this allowance in the quarter ended June 30, 2011, principally due to a reduction in expected losses upon liquidation of foreclosed properties as well as a decline in the amount of delinquencies in the Bank's portfolio of conventional mortgage loans. See Item 7 — Management's Discussion and Analysis of Financial Condition and Results of Operations — Critical Accounting Estimates — Allowance for Loan Losses in the 2010 Annual Report for a description of the Bank's methodology for estimating the allowance for loan losses.

The following tables present the Bank's delinquent loans and allowance for credit losses activity (dollars in thousands).

Higher-Risk Loans. The Bank's portfolio includes certain higher-risk conventional mortgage loans. These include high loan-to-value ratio mortgage loans and subprime mortgage loans. The higher-risk loans represent a relatively small portion of the Bank's total conventional portfolio (9.0 percent by outstanding principal balance), but a disproportionately higher portion of the conventional portfolio delinquencies (39.3 percent by outstanding principal balance). The Bank's allowance for loan losses reflects the expected losses associated with these higher-risk loan types. The table below shows the balance of higher-risk conventional mortgage loans and their delinquency rates as of September 30, 2011.

Summary of Higher-Risk Conventional Mortgage Loans As of September 30, 2011 (dollars in thousands)

_______________________

(1)Subprime loans are loans to borrowers with FICO® credit scores 660 or lower. FICO is a widely used credit-industry model developed by Fair Isaac and Company, Inc. to assess borrower credit quality with scores ranging from a low of 300 to a high of 850.

(2)High loan-to-value loans have an estimated current loan-to-value ratio greater than 100 percent based on movements in property values in the core-based statistical areas where the property securing the loan is located.

(3)These loans are subprime and also have a current estimated loan-to-value ratio greater than 100 percent.

The Bank's portfolio consists solely of fixed-rate conventionally amortizing first-lien mortgage loans. The portfolio does not include adjustable-rate mortgage loans, pay-option adjustable-rate mortgage loans, interest-only mortgage loans, junior lien mortgage loans, or loans with initial teaser rates.

The Bank is exposed to credit risk from mortgage insurance companies that provide credit enhancement in place of the participating financial institution and for primary mortgage insurance coverage on individual loans. As of September 30, 2011, the Bank was the beneficiary of primary mortgage insurance coverage on $214.1 million of conventional mortgage loans, and the Bank was the beneficiary of supplemental mortgage insurance coverage on mortgage pools with a total unpaid principal balance of $36.1 million. Eight mortgage insurance companies provide all of the coverage under these policies.

As of October 31, 2011, all of these mortgage insurance companies have a credit rating of triple-B or lower (or its equivalent) by at least one NRSRO as presented in the below table. Ordinarily the Bank does not accept primary mortgage insurance from a mortgage insurance company unless that company is rated at least triple-B by S&P (although the Bank may accept lower rated mortgage insurance provided the Bank obtains additional credit enhancement in such form as it deems appropriate and of substance sufficient to mitigate the risks of relying on such lower rated primary mortgage insurance). Given that only two mortgage insurance companies have a credit rating of triple-B as of October 31, 2011, the Bank could develop increasing concentrations of exposure to those mortgage insurance companies. However, the Bank has established and maintains limits on exposure to individual mortgage insurance companies in an effort to mitigate those concentration risks. Those exposure limits

87

could, in turn, eventually lead to fewer mortgage loan investment opportunities for the Bank.

The Bank has analyzed its potential loss exposure to all of the mortgage insurance companies and does not expect incremental losses due to these ratings. This expectation is based on the credit-enhancement features of the Bank's master commitments (exclusive of mortgage insurance), the underwriting characteristics of the loans that back the Bank's master commitments, the seasoning of the loans that back these master commitments, and the strong performance of the loans to date. The Bank closely monitors the financial condition of these mortgage insurance companies. Further, the Bank requires that all new supplemental mortgage insurance policies be with companies rated AA- or higher by S&P. However, none of the eight mortgage insurance companies previously approved by the Bank are currently eligible to write new supplemental mortgage insurance policies for loan pools sold to the Bank. The Bank does not invest in mortgage loans that rely on supplemental mortgage insurance to be eligible Bank investments.

(1)On October 20, 2011, the Arizona Department of Insurance took possession and control of PMI Mortgage Insurance Company and beginning October 24, 2011, PMI Mortgage Insurance Company has been directed to only pay 50% of the claim amounts with the remaining claim amounts being deferred until the company is liquidated.

Debt Financing — Consolidated Obligations

At September 30, 2011 and December 31, 2010, outstanding COs, including both CO bonds and CO discount notes, totaled $43.1 billion and $53.6 billion, respectively. CO bonds are generally issued with either fixed-rate coupon-payment terms or variable-rate coupon-payment terms that use a variety of indices for interest-rate resets. Some of the fixed-rate bonds issued by the Bank are callable bonds that may be redeemed at par on one or more dates prior to their maturity date. In addition, to meet the needs of the Bank and of certain investors in COs, fixed-rate bonds and variable-rate bonds may also contain certain provisions that may result in complex coupon-payment terms and call or amortization features. When such COs (structured bonds) are issued, the Bank enters into interest-rate-exchange agreements containing offsetting features, which effectively change the characteristics of the bond to those of a simple variable-rate bond.

See Item 1 — Notes to the Financial Statements — Note 12 — Consolidated Obligations for a summary of CO bonds by contractual maturity dates and call dates as of September 30, 2011, and December 31, 2010. CO bonds outstanding at September 30, 2011, and December 31, 2010, include issued callable bonds totaling $2.7 billion and $5.2 billion, respectively.

88

CO discount notes are also a significant funding source for the Bank. CO discount notes are short-term instruments with maturities ranging from overnight to one year. The Bank uses CO discount notes primarily to fund short-term advances and investments and longer-term advances and investments with short repricing intervals. CO discount notes comprised 24.8 percent and 34.5 percent of outstanding COs at September 30, 2011, and December 31, 2010, respectively, but accounted for 97.5 percent and 97.3 percent of the proceeds from the issuance of COs during the nine months ended September 30, 2011 and 2010, respectively, due, in particular, to the Bank's frequent overnight CO discount note issuances.

Deposits

At September 30, 2011, and December 31, 2010, deposits totaled $740.9 million and $745.5 million, respectively.

The following table presents term deposits issued in amounts of $100,000 or greater at September 30, 2011, and December 31, 2010.

Derivative Instruments

All derivative instruments are recorded on the statement of condition at fair value, and are classified as assets or liabilities according to the net fair value of derivatives aggregated by counterparty. Derivative assets' net fair value, net of cash collateral and accrued interest, totaled $16.4 million and $14.8 million as of September 30, 2011, and December 31, 2010, respectively. Derivative liabilities' net fair value, net of cash collateral and accrued interest, totaled $896.4 million and $729.2 million as of September 30, 2011, and December 31, 2010, respectively.

The following table presents a summary of the notional amounts and estimated fair values of the Bank's outstanding derivative instruments, excluding accrued interest, and related hedged item by product and type of accounting treatment as of September 30, 2011, and December 31, 2010. The hedge designation “fair value” represents the hedge classification for transactions that qualify for hedge-accounting treatment and are hedging changes in fair value attributable to changes in the designated benchmark interest rate, which is LIBOR. The hedge designation "cash flow" represents a hedge strategy that hedges the exposure to variability in expected future cash flows. The hedge designation “economic” represents hedge strategies that do not qualify for hedge accounting, but are acceptable hedging strategies under the Bank's risk-management policy.

The following four tables provide a summary of the Bank's hedging relationships for fair-value hedges of advances and COs that qualify for hedge accounting by year of contractual maturity, next put date for putable advances, and next call date for callable COs. Interest accruals on interest-rate-exchange agreements in qualifying hedge relationships are recorded as interest income on advances and interest expense on COs in the statement of operations. The notional amount of derivatives in qualifying hedge relationships of advances and COs totals $19.9 billion, representing 90.7 percent of all derivatives outstanding as of September 30, 2011. Economic hedges are not included within the four tables below.

The Bank engages in derivatives directly with affiliates of certain of the Bank's members, which act as derivatives dealers to the Bank. These derivative contracts are entered into for the Bank's own risk-management purposes and are not related to requests from the Bank's members to enter into such contracts. See Item 1 — Notes to the Financial Statements — Note 19 — Transactions with Related Parties for outstanding derivative contracts with affiliates of members.

Derivative Instruments Credit Risk. The Bank is subject to credit risk on derivative instruments. This risk arises from the risk of counterparty default on the derivative contract. The amount of loss created by default is the replacement cost, or current positive fair value, of the defaulted contract, net of any collateral held by the Bank or pledged to counterparties by the Bank. The credit risk to the Bank arising from unsecured credit exposure on derivatives is mitigated by the credit quality of the counterparties and by the early termination ratings triggers contained in all master derivatives agreements. The Bank enters into new derivative trades only with nonmember institutions that have long-term senior unsecured credit ratings that are at or above single-A (or its equivalent) by S&P and Moody's, although risk-reducing trades may be approved for counterparties whose ratings have fallen below these ratings. Management actively monitors these exposures and the credit quality of its counterparties, including assessments of each counterparty's financial performance, capital adequacy and sovereign support as well as related market signals. The Bank intends to reduce or suspend credit limits and/or seek to reduce existing exposures as a result of these monitoring activities. As an example, during the third quarter of 2011, the Bank has reduced or restricted trading with certain European counterparties based on the European sovereign debt crisis. The Bank does not enter into interest-rate-exchange agreements with other FHLBanks. The Bank uses master-netting agreements to reduce its credit exposure from counterparty defaults. The master agreements contain bilateral-collateral-exchange provisions that require credit exposures beyond a defined amount to be secured by U.S. federal government or GSE-issued securities or cash. Exposures are measured daily, and adjustments to collateral positions are made as necessary to minimize the Bank's exposure to credit risk. The master agreements generally provide for smaller amounts of unsecured exposure to lower-rated counterparties. These agreements are bilateral and generally require the Bank to deliver additional collateral to the counterparty if the Bank's credit rating is downgraded by an NRSRO, which could increase the Bank's exposure to loss in the event of a default by a counterparty to which the Bank was the net obligor, as further detailed in Item 1 — Notes to the Financial Statements — Note 10 — Derivatives and Hedging Activities.

See Item 1 — Notes to the Financial Statements — Note 10 — Derivatives and Hedging Activities for additional information on the Bank's credit risks from its derivative instruments.

As illustrated in the following table, the Bank's maximum credit exposure on interest-rate-exchange agreements is much less than the notional amount of the agreements. Additionally, commitments to invest in mortgage loans are reflected in the following table as derivative instruments. The Bank does not collateralize these commitments. However, should the participating financial institution fail to deliver the mortgage loans as agreed, the member institution is charged a fee to compensate the Bank for nonperformance of the agreement.

Terms for outstanding investments are currently overnight to 35 days. The Bank also engages in short-term secured reverse-repurchase agreements with affiliates of these counterparties. All of these counterparties and/or their affiliates buy, sell, and distribute the Bank's COs.

RISK MANAGEMENT

93

Operational Risk

The Bank is subject to operational risk, which is the risk of unexpected loss resulting from human error, fraud, unenforceability of legal contracts, or deficiencies in internal controls or information systems. Operational risk includes risk arising from breaches of the Bank's cybersecurity or other cyber incidents that could result in a failure or interruption of the Bank's information technology or other technology. The Bank has not experienced a disruption in its information systems or other technology that has had a material adverse impact on the Bank. However, the Bank relies heavily on its information systems and other technology to conduct and manage its business and so failures or interruptions of these information systems or other technology could have a material adverse impact on the Bank's financial condition and results of operations. The Bank takes several steps to protect its information systems and technology, including operational redundancy and supplier diversity along with monitored physical and logical security controls to protect the Bank's information systems and data.

Additionally, most of the Bank's information systems have been co-located with a third party service provider on whom the Bank is reliant to provide a secure location and a stable operating environment for these systems. Any failure to provide such stability or security by the third party service provider could result in failures or interruptions in the Bank's ability to conduct business. The Bank takes several steps to mitigate the risks of its reliance on this third party service provider, including physical and monitored logical security controls to protect the Bank's information systems and data within the co-location space along with maintaining redundancy of systems at an alternate location for business continuity. Additionally, the Bank reviews the provider's controls report annually and monitors and meets with the provider on a regular basis. Additionally, the Bank has a disaster-recovery site intended to provide seamless continuity of operations in the event that the Bank's primary information systems become unavailable, but there can be no assurance that the disaster-recovery site will work as intended in the event of an actual disruption or failure.

Further, the Bank's AHP and MPF investment activities rely on the secure processing, storage, and transmission of a large volume of private borrower information, such as names, residential addresses, social security numbers, credit rating data, and other consumer financial information. The Bank takes several steps to protect such data, including information technology and security general computing controls governing access to programs and data along with physical and logical security. Additional, the Bank reviews related third party service providers' controls reports annually. Despite these steps, this information could be exposed in several ways, including through unauthorized access to the Bank's computer systems, computer viruses that attack the Bank's computer systems, software or networks, accidental delivery of information to an unauthorized party, and loss of encrypted media containing this information. Any of these events could result in financial losses, legal and regulatory sanctions, and reputational damage.

For additional information on operational risk and the Bank's approaches to it, see Item 7 — Management's Discussion and Analysis of Financial Condition and Results of Operations — Risk Management — Operational Risk of the 2010 Annual Report.

LIQUIDITY AND CAPITAL RESOURCES

The Bank's financial strategies are designed to enable the Bank to expand and contract its assets, liabilities, and capital in response to changes in membership composition and member credit needs. The Bank's primary source of liquidity is its access to the capital markets through CO issuance, which is described in Item 1 — Business — Consolidated Obligations of the 2010 Annual Report. The Bank's equity capital resources are governed by the Bank's capital plan, certain portions of which are described under — Capital below as well as by applicable legal and regulatory requirements.

Liquidity

Internal Sources of Liquidity

The Bank maintains structural liquidity to ensure that it meets its day-to-day business needs and its contractual obligations with normal sources of funding. The Bank defines structural liquidity as the difference between projected sources and uses of funds (projected net cash flow) adjusted to include certain assumed contingent, noncontractual obligations or behavioral assumptions (cumulative contingent obligations). Cumulative contingent obligations include the assumption that all maturing advances are renewed except for those from large, highly rated members; member overnight deposits are withdrawn at a rate of 50 percent per day; and commitments (MPF and other commitments) are taken down at a conservatively projected pace. The Bank defines available liquidity as the sources of funds available to the Bank through its normal access to the capital markets, subject to leverage, credit line capacity, and collateral constraints. The risk-management policy requires the Bank to maintain structural liquidity each day so that any excess of uses over sources is covered by available liquidity for a four-week

94

forecast period and 50 percent of the excess of uses over sources is covered by available liquidity over eight- and 12-week forecast periods. In addition to these minimum requirements, management measures structural liquidity over a three-month forecast period. If the Bank's excess of uses over sources is not fully covered by available liquidity over a two-month or three-month forecast period, a management action trigger is breached and senior management is immediately notified so that a decision can be made as to whether immediate remedial action is necessary. The following table shows the Bank's structural liquidity as of September 30, 2011.

(1)  Projected net cash flow equals projected sources of funds less projected uses of funds based on contractual maturities or expected option exercise periods, as applicable.

(2) Available borrowing capacity is the CO issuance capacity based on achieving leverage up to the Bank's internal minimum capital requirement. For information on this internal minimum capital requirement, see — Capital Rule — Internal Minimum Capital Plan Requirements in Excess of Regulatory Requirements.

In accordance with Finance Agency regulations, the Bank also maintains contingency liquidity plans designed to enable it to meet its obligations in the event of operational disruption at the Bank, the Office of Finance, the capital markets, or any other event that precludes issuance of COs. These regulations require the Bank to maintain highly liquid assets at all times in an amount equal to or greater than the aggregate amount of all anticipated maturing advances over the following five days. The Bank maintained material compliance with this requirement at all times during the nine months ended September 30, 2011. As of September 30, 2011, and December 31, 2010, the Bank held a surplus of $11.9 billion and $13.8 billion, respectively, of contingency liquidity for the following five days, exclusive of access to the proceeds of CO debt issuance. The following table demonstrates the Bank's contingency liquidity as of September 30, 2011.

Contingency Liquidity As of September 30, 2011 (dollars in thousands)
	Cumulative Fifth Business Day
Projected net cash flow (1)	$	95,737
Contingency borrowing capacity (exclusive of CO debt issuance)	11,845,324
Net contingency borrowing capacity	$	11,941,061

_______________________

(1) Projected net cash flow equals projected sources of funds less projected uses of funds based on contractual maturities or expected option exercise periods, as applicable.

In addition, certain Finance Agency guidance requires the Bank to maintain sufficient liquidity, through short-term investments, in an amount at least equal to the Bank's anticipated cash outflows under two different scenarios. One scenario assumes that the Bank cannot borrow funds from the capital markets for a period of 15 days and that during that time members do not renew any maturing, prepaid, and called advances. The second scenario assumes that the Bank cannot borrow funds from the capital markets for five days and that during that period the Bank will renew maturing and called advances for all members except very large, highly rated members. The Bank was in material compliance with these liquidity requirements at all times during the quarter ended September 30, 2011.

95

Further, the Bank is sensitive to maintaining an appropriate funding balance between its assets and liabilities and has an established policy that limits the potential gap between assets with maturities inclusive of projected prepayments greater than one year funded by liabilities maturing inclusive of projected calls in less than one year. The established policy limits this imbalance to a gap of 20 percent of total assets with a management action trigger should this gap exceed 10 percent of total assets. The Bank maintained material compliance with this requirement at all times during the three months ended September 30, 2011. During the three months ended September 30, 2011, this gap averaged 0.8 percent (maximum level 1.1 percent and minimum level 0.1 percent). As of September 30, 2011, this gap was 1.1 percent, compared with 3.8 percent at December 31, 2010.

External Source of Liquidity

The Bank has a source of emergency external liquidity through the Federal Home Loan Banks P&I Funding Contingency Plan Agreement. Under the terms of that agreement, in the event the Bank does not fund its principal and interest payments under a CO by deadlines established in the agreement, the other FHLBanks will be obligated to fund any shortfall to the extent that any of the other FHLBanks have a net positive settlement balance (that is, the amount by which end-of-day proceeds received by such FHLBank from the sale of COs on that day exceeds payments by such FHLBank on COs on the same day) in its account with the Office of Finance on the day the shortfall occurs. The Bank would then be required to repay the funding FHLBanks. Neither the Bank nor any of the other FHLBanks have ever drawn upon this agreement.

Financial Conditions for FHLBank Debt

During the period covered by this report the Bank has experienced CO issuance costs that were relatively consistent with recent past quarters. Demand for COs has remained stable. Throughout the period covered by this report, CO bonds were issued at yields that were generally at or below equivalent-maturity LIBOR swap yields for debt maturing in less than five years, while longer term issues bore funding costs that were typically higher than equivalent-maturity LIBOR swap yields. The Bank continues to experience similar pricing into the fourth quarter of 2011.

On August 8, 2011, S&P downgraded the Bank's long-term credit rating to AA+ with a negative outlook based on its downgrade of the long-term sovereign credit rating of the United States from AAA to AA+ with a negative outlook. This and other credit rating agency developments have occurred during the period covered by this report. Although the Bank experienced favorable pricing throughout the period covered by this report, these developments and/or further downgrades of the Bank's credit ratings could adversely impact the Bank's market access and/or funding costs. During the period covered by this report, the Bank has not discerned an adverse impact on the Bank's market access and/or funding costs based on the downgrade.

The Bank's total capital increased $127.6 million to $3.4 billion at September 30, 2011, from $3.3 billion at December 31, 2010. The increase was attributable to the net reduction of $121.4 million in accumulated other comprehensive loss, an $86.9 million increase in retained earnings, and the purchase of $60.1 million of capital stock by members during the nine months ended September 30, 2011. These increases to capital were offset with the transfer of $140.8 million of capital stock to mandatorily redeemable capital stock. The reduction of accumulated other comprehensive loss was primarily attributable to the accretion of $125.2 million of non-credit losses recognized in prior periods with respect to private-label MBS deemed to be other-than-temporarily impaired and due to $58.5 million in non-credit losses that were reclassified from accumulated other comprehensive loss and charged to earnings. This reclassification was for securities that were previously other-than-temporarily impaired that incurred additional credit losses during the nine months ended September 30, 2011.

The Bank's ability to expand in response to member-credit needs is based primarily on the capital-stock requirements for advances. Members are required to increase their capital-stock investment in the Bank as their outstanding advances increase, as described in Item 1 — Business — Capital Resources of the 2010 Annual Report. As discussed in that Item, the Bank may either repurchase or redeem excess capital stock (stock in excess of what members are required to hold) in its sole discretion, however, the Bank continues its moratorium on excess stock repurchases, except in limited instances of former member insolvency. During the nine months ended September 30, 2011, the Bank did not repurchase excess capital stock.

Subject to applicable law, the Bank redeems capital stock for any member that either gives notice of intent to withdraw from membership, or becomes a nonmember due to merger or acquisition, charter termination, or involuntary termination of membership following the expiry of the stock redemption period. Capital stock subject to a stock redemption period is reclassified to mandatorily redeemable capital stock in the liability section of the statement of condition. Mandatorily redeemable capital stock totaled $227.4 million and $90.1 million at September 30, 2011, and December 31, 2010, respectively. The following table summarizes the anticipated stock-redemption period for these shares of capital stock as of September 30, 2011, and December 31, 2010 (dollars in thousands):

At September 30, 2011, and December 31, 2010, members and nonmembers with capital stock outstanding held $2.1 billion and $1.9 billion, respectively, in excess capital stock. The following table summarizes member capital stock requirements as of September 30, 2011, and December 31, 2010 (dollars in thousands):

_______________________

(1) Total stock-investment requirement is rounded up to the nearest $100 on an individual member basis.

(2) Class B capital stock outstanding includes mandatorily redeemable capital stock.

The FHLBank Act and Finance Agency regulations specify that each FHLBank must meet certain minimum regulatory capital requirements. The Bank is in compliance with these requirements as discussed in Item 1 — Notes to the Financial Statements — Note 14 — Capital. Additionally, the Bank is subject to a capital rule under Finance Agency regulations (the Capital Rule) and has adopted additional minimum capital requirements, each of which is described under — Capital Rule and — Internal Minimum Capital Requirement in Excess of Regulation Requirements, respectively.

Internal Capital Practices and Policies

The Bank targets an operating range of 4.0 percent to 7.5 percent for its capital ratio, a range adopted in conjunction with the Bank's capital preservation measures. The Bank's capital ratio was 8.5 percent at September 30, 2011, a ratio in excess of the targeted operating range. This results principally from the continuing moratorium on the repurchase of excess stock despite a significant decline in advances balances since 2008, which moratorium is continued for the reasons discussed under — Executive Summary.

Capital Rule

The Capital Rule, among other things, establishes criteria for four capital classifications and corrective action requirements for FHLBanks that are classified in any classification other than adequately capitalized. The Capital Rule requires the Director of the Finance Agency to determine on no less than a quarterly basis the capital classification of each FHLBank. By letter dated September 30, 2011, the Acting Director of the Finance Agency notified the Bank that, based on June 30, 2011, financial information, the Bank met the definition of adequately capitalized under the Capital Rule. The Acting Director of the Finance Agency has not yet notified the Bank of its capital classification based on September 30, 2011, financial information.

Internal Minimum Capital Requirements in Excess of Regulatory Requirements.

To provide further protection for the Bank's capital base, the Bank maintains an internal minimum capital requirement whereby the amount of paid-in capital stock and retained earnings must exceed the sum of the Bank's regulatory capital requirement plus its retained earnings target. As of September 30, 2011, this requirement equaled $2.9 billion, which was satisfied by the Bank's actual regulatory capital of $4.1 billion.

Capital Plan Amendments and Restricted Retained Earnings

On August 5, 2011, the Bank provided notice to its members of certain amendments to its capital plan that became effective on September 5, 2011, and are intended to conform the Bank's capital plan with the Capital Agreement. Due to the satisfaction of the REFCorp obligation, the Capital Agreement (the terms of which are reflected in the Bank's capital plan, as amended),

97

among other things, obligates each FHLBank to allocate an amount at least equal to 20 percent of its quarterly net income to a restricted retained earnings account beginning with the quarter ended September 30, 2011, and continuing for each subsequent calendar quarter for so long as such FHLBank's restricted retained earnings account is less than 1.0 percent of the daily average carrying value of such FHLBank's outstanding total consolidated obligations (excluding fair-value adjustments) for that calendar quarter. At September 30, 2011, the amount in the restricted retained earnings account was $10.0 million compared with the Bank's total required contribution to the account, which was $454.4 million on that date. Amounts in the restricted retained earnings account cannot be used to pay dividends.

Additional details of the Capital Agreement, the details of which informed the amendments to the Bank's capital plan, are set forth in the 2010 Annual Report under Item 7 — Management's Discussion and Analysis of Financial Condition and Results of Operations — Liquidity and Capital Resources — Joint Capital Enhancement Agreement. Further, in connection with the receipt of the Finance Agency's approval of the capital plan amendments, the FHLBanks amended the Capital Agreement that, among other changes:

• restrict the payment of dividends from amounts in the restricted retained earnings account for at least one year following the termination of the Capital Agreement; and

• provide for certain procedural mechanisms for determining when an automatic termination event has occurred.

Retained Earnings Target. The Bank's retained earnings target remains at $925.0 million, reflecting continuing uncertainty about the economy and housing recovery. Unemployment remains persistently high and home prices and sales are stagnant, with significant amounts of inventory yet to be cleared. At September 30, 2011, the Bank had total retained earnings of $336.1 million, consisting of $326.1 million in unrestricted retained earnings and $10.0 million in restricted retained earnings. For information on how the Bank adjusts its retained earnings target, including in response to Finance Agency regulations, orders, or guidance, see Item 7 — Management's Discussion and Analysis of Financial Condition and Results of Operations — Liquidity and Capital Resources — Retained Earnings Target and Dividends in the 2010 Annual Report.

The retained earnings target will be sensitive to changes in the Bank's risk profile, whether favorable or unfavorable. For example, a further sharp deterioration in expected performance of loans underlying private-label MBS could cause the Bank to adopt a higher target, whereas sustained stabilization or improvement of the performance of these loans may lead to a reduction in the retained earnings target. Management has considered the likelihood of the Bank meeting the retained earnings target as it evolves over a five-year forecast horizon initially established in 2009, and has concluded that it is impossible to reliably project how the retained earnings target will evolve, and thus, when the retained earnings target will be achieved, due to uncertainties about exogenous factors impacting the Bank’s risk profile. Such factors include general economic conditions, particularly the U.S. housing economy, and the regulatory environment.

Off-Balance-Sheet Arrangements and Aggregate Contractual Obligations

The Bank's significant off-balance-sheet arrangements consist of the following:

• commitments that obligate the Bank for additional advances;

• standby letters of credit;

• commitments for unused lines-of-credit advances;

• standby bond-purchase agreements with state housing authorities; and

• unsettled COs.

Off-balance-sheet arrangements are more fully discussed in Item 1 — Notes to the Financial Statements — Note 18 — Commitments and Contingencies.

Through the second quarter of 2011, the Bank was required to pay 20 percent of its net earnings (after its AHP obligation) to REFCorp to support payment of part of the interest on bonds issued by REFCorp. Additionally, the FHLBanks must annually set aside for the AHP the greater of an aggregate of $100 million or 10 percent of the current year's income before charges for AHP (but after expenses for REFCorp). Based on the Bank's net income of $94.9 million for the nine months ended September 30, 2011, the Bank's AHP assessment was $10.6 million and the REFCorp assessment was $11.1 million for the nine months ended September 30, 2011. See Item 1 — Business — Assessments of the 2010 Annual Report for additional

98

information regarding REFCorp and AHP.

CRITICAL ACCOUNTING ESTIMATES

The preparation of financial statements in accordance with GAAP requires management to make a number of judgments, estimates, and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities (if applicable), and the reported amounts of income and expenses during the reported periods. Although management believes these judgments, estimates, and assumptions to be reasonably accurate, actual results may differ.

The Bank has identified five accounting estimates that it believes are critical because they require management to make subjective or complex judgments about matters that are inherently uncertain, and because of the likelihood that materially different amounts would be reported under different conditions or using different assumptions. These estimates include accounting for derivatives, the use of fair-value estimates, accounting for deferred premiums and discounts on prepayable assets, the allowance for loan losses, and other-than-temporary-impairment of investment securities. The Bank's Audit Committee of the board of directors has reviewed these estimates. The assumptions involved in applying these policies are discussed in Item 7 — Management's Discussion and Analysis of Financial Condition and Results of Operations — Critical Accounting Estimates in the 2010 Annual Report.

As of September 30, 2011, the Bank had not made any significant changes to the estimates and assumptions used in applying its critical accounting policies and estimates from those used to prepare its audited financial statements. Also described below are the results of the sensitivity analysis for private-label MBS.

Other-Than-Temporary Impairment of Investment Securities

See Item 1 — Notes to the Financial Statements — Note 6 — Other-Than-Temporary Impairment for additional information related to management's other-than-temporary impairment analysis for the current period.

In addition to evaluating its residential private-label MBS under a base-case (or best estimate) scenario, a cash-flow analysis was also performed for each of these securities under a more stressful housing price index scenario that was determined by the OTTI Governance Committee.

The more stressful scenario was based on a housing price forecast that was five percentage points lower at the trough than the base-case scenario followed by a flatter recovery path. The Bank's base-case housing price forecast as of September 30, 2011, assumed current-to-trough home price declines ranging from 0.0 percent (for those housing markets that are believed to have reached their trough) to 10.0 percent. For those markets for which further home price declines are anticipated, such declines were projected to occur over the three- to nine-month period beginning July 1, 2011. From the trough, home prices were projected to recover using one of five different recovery paths that vary by housing market. Under the more stressful scenario, current-to-trough home price declines were projected to range from 5.0 percent to 15.0 percent over the three- to nine-month period beginning July 1, 2011. The following table presents projected home price recovery ranges by year under the base case and adverse case scenario.

	Base Case			Adverse Case
	Range %			Range %
Year 1	0.0	—	2.8	0.0	—	1.9
Year 2	0.0	—	3.0	0.0	—	2.0
Year 3	1.5	—	4.0	1.0	—	2.7
Year 4	2.0	—	5.0	1.3	—	3.4
Years 5 and 6	2.0	—	6.0	1.3	—	4.0
Thereafter	2.3	—	5.6	1.5	—	3.8

The following table represents the impact on credit-related other-than-temporary impairment using the more stressful scenario of the housing price index, described above, compared with actual credit-related other-than-temporary impairment recorded using our base-case housing price index assumptions as of September 30, 2011 (dollars in thousands):

RECENT ACCOUNTING DEVELOPMENTS

See Item 1 — Notes to the Financial Statements — Note 2 — Recently Issued Accounting Standards and Interpretations for a discussion on recent accounting developments.

LEGISLATIVE AND REGULATORY DEVELOPMENTS

The legislative and regulatory environment for the Bank continues to undergo significant change as financial regulators issue proposed and/or final rules to implement the Dodd-Frank Act and the Housing and Economic Reform Act of 2008 and as Congress considers proposals for housing GSE reform.

Dodd-Frank Act

The Dodd-Frank Act will likely impact the FHLBanks' business operations, funding costs, rights, obligations, and/or the environment in which the FHLBanks carry out their housing finance mission. Certain regulatory actions during the period covered by this report resulting from the Dodd-Frank Act that could have an important impact on the Bank are summarized below, although the full effect of the Dodd-Frank Act will become known only after the required regulations, studies, and reports are issued and finalized.
 

New Requirements for the Bank's Derivatives Transactions.

The Dodd-Frank Act provides for new statutory and regulatory requirements for derivative transactions, including those used by the Bank to hedge its interest rate and other risks. As a result of these requirements, certain derivative transactions will be required to be cleared through a third-party central clearinghouse and traded on regulated exchanges or new swap execution facilities.

Mandatory Clearing of Derivatives Transactions. The CFTC has issued a final rule regarding the process pursuant to which it will determine which types of swaps will be subject to mandatory clearing, but has not yet made any such determinations. The CFTC has also proposed a rule setting forth an implementation schedule for effectiveness of its mandatory clearing determinations. Pursuant to this proposed rule, regardless of when the CFTC determines that a type of swap is required to be cleared, such mandatory clearing would not take effect until certain rules being promulgated by the CFTC and the SEC under the Dodd-Frank Act have been finalized. In addition, the proposed rule provides that each time the CFTC determines that a type of swap is required to be cleared, the CFTC would have the option to implement such requirement in three phases. Under the proposed rule, the Bank would be a “category 2 entity” and would therefore have to comply with mandatory clearing requirements for a particular swap during phase 2 (within 180 days of the CFTC’s issuance of such requirements). Based on the CFTC’s proposed implementation schedule and the time periods set forth in the rule for CFTC determinations regarding mandatory clearing, it is not expected that any of our swaps will be required to be cleared until the third quarter of 2012, at the earliest.

Collateral Requirements for Cleared Swaps. Cleared swaps will be subject to initial and variation margin requirements established by the clearinghouse and its clearing members. While clearing swaps could reduce counterparty credit risk, the margin requirements for cleared swaps have the potential of making derivative transactions more costly. In addition, mandatory swap clearing will require us to enter into new relationships and accompanying documentation with clearing members (which the Bank is currently negotiating) and additional documentation with our swap counterparties.

The CFTC has issued a proposed rule requiring that collateral posted by swap customers to a clearinghouse in connection with cleared swaps be legally segregated on a customer-by-customer basis. However, in connection with this proposed rule the CFTC has left open the possibility that customer collateral would not have to be legally segregated but could instead be

100

commingled with all collateral posted by other customers of our clearing member. Such commingling would put our collateral at risk in the event of a default by another customer of the Bank’s clearing member. To the extent the CFTC’s final rule places our posted collateral at greater risk of loss in the clearing structure than under the current over-the-counter market structure, the Bank could be adversely impacted.

Definitions of Certain Terms under New Derivatives Requirements. The Dodd-Frank Act will require swap dealers and certain other large users of derivatives to register as “swap dealers” or “major swap participants,” as the case may be, with the CFTC and/or the SEC. Based on the definitions in the proposed rules jointly issued by the CFTC and SEC, it does not appear likely that the Bank will be required to register as a “major swap participant,” although this remains a possibility. Also, based on the definitions in the proposed rules, it does not appear likely that the Bank will be required to register as a “swap dealer” for the derivative transactions that the Bank enters into with dealer counterparties for the purpose of hedging and managing our interest rate risk.

It is also unclear how the final rule will treat the call and put optionality in certain advances to our members. The CFTC and SEC have issued joint proposed rules further defining the term “swap” under the Dodd-Frank Act. These proposed rules and accompanying interpretive guidance attempt to clarify what products will and will not be regulated as “swaps.” While it is unlikely that advance transactions between us and the Bank's borrowers will be treated as “swaps,” the proposed rules and accompanying interpretive guidance are not entirely clear on this issue.

Depending on how the terms “swap” and “swap dealer” are defined in the final regulations, the Bank could be faced with the business decision of whether to continue to offer certain types of advance products to member customers if those transactions would require us to register as a swap dealer. Designation as a swap dealer would subject us to significant additional regulation and cost including, without limitation, registration with the CFTC, new internal and external business conduct standards, additional reporting requirements, and additional swap-based capital and margin requirements. Even if the Bank is designated as a swap dealer as a result of our advance activities, the proposed regulations would permit us to apply to the CFTC to limit such designation to those specified activities for which the Bank is acting as a swap dealer. Upon such designation, our hedging activities would not be subject to the full requirements that will generally be imposed on traditional swap dealers.

Uncleared Derivatives Transactions. The Dodd-Frank Act will also change the regulatory landscape for derivative transactions that are not subject to mandatory clearing requirements (uncleared trades). While the Bank expects to continue to enter into uncleared trades on a bilateral basis, such trades will be subject to new regulatory requirements, including mandatory reporting, documentation, and minimum margin and capital requirements. Under the proposed margin rules, the Bank will have to post both initial margin and variation margin to our swap dealer counterparties, but could be eligible in both instances for modest unsecured thresholds as “low-risk financial end users.” Pursuant to additional Finance Agency proposed provisions, the Bank will be required to collect both initial margin and variation margin from our swap dealer counterparties, without any unsecured thresholds. These margin requirements and any related capital requirements could adversely impact the liquidity and pricing of certain uncleared derivative transactions entered into by us, making such trades more costly.

The CFTC has proposed a rule setting forth an implementation schedule for the effectiveness of the new margin and documentation requirements for uncleared swaps. Pursuant to the proposed rule, regardless of when the final rules regarding these requirements are issued, such rules would not take effect until (1) certain other rules being promulgated under the Dodd-Frank Act take effect and (2) a certain additional time period has elapsed. The length of this additional time period depends on the type of entity entering into the uncleared swaps. The Bank would be a “category 2 entity” and would therefore have to comply with the new requirements during phase 2 (within 180 days of the effectiveness of the final applicable rulemaking). Accordingly, it is not likely that the Bank would have to comply with such requirements until the third quarter of 2012, at the earliest.

Temporary Exemption from Certain Provisions. While certain provisions of the Dodd-Frank Act took effect on July 16, 2011, the CFTC has issued an order temporarily exempting persons or entities with respect to provisions of Title VII of the Dodd-Frank Act that reference “swap dealer,” “major swap participant,” “eligible contract participant,” and “swap.” These exemptions will expire upon the earlier of: (i) the effective date of the applicable final rule further defining the relevant terms; or (ii) December 31, 2011. The CFTC has recently proposed an amendment to this order that would extend the exemptions contained in the existing order until the earlier of (i) the effective date of the applicable final rules further defining the relevant terms; or (ii) July 16, 2012. In addition, the provisions of the Dodd-Frank Act that will have the most effect on us did not take effect on July 16, 2011, but will take effect no less than 60 days after the CFTC publishes final regulations implementing such provisions. The CFTC is expected to publish such final regulations during the fourth quarter of 2011 or the first quarter of 2012, but it is not expected that such final regulations will become effective until the first or second quarter of 2012, and delays beyond that time are possible. In addition, as discussed above, mandatory clearing requirements and new margin and documentation requirements for uncleared swaps may be subject to additional implementation schedules, further delaying the

101

effectiveness of such requirements.

The Bank, together with the other FHLBanks, is actively participating in the development of the regulations under the Dodd-Frank Act by formally commenting to the regulators regarding a variety of rulemakings that could impact the FHLBanks. The Bank and the other FHLBanks are also working to implement the processes and documentation necessary to comply with the Dodd-Frank Act's new requirements for derivatives.

Finance Agency Regulation Action

Home Affordable Refinance Program Changes. The Finance Agency, Fannie Mae and Freddie Mac (the Enterprises) have announced a series of changes to the Home Affordable Refinance Program that are intended to assist more eligible borrowers who can benefit from refinancing their home mortgage. The changes include lowering or eliminating certain risk-based fees, removing the current 125 percent loan-to-value ceiling on fixed-rate mortgages that are purchased by the Enterprises, waiving certain representations and warranties, eliminating the need for a new property appraisal where there is a reliable automated valuation model estimate provided by the Enterprises, and extending the end date for the program until December 31, 2013 for loans originally sold to the Enterprises on or before May 31, 2009.If the program results in a significant number of prepayments on mortgage loans underlying the Bank's investments in agency MBS, such investments will be paid off in advance of the Bank's expectations subjecting the Bank to associated reinvestment risk. Accordingly, the Bank's investment income and, in turn, the Bank's financial condition and results of operations, could be adversely impacted as a result of the program.

Final Rule on Conservatorship/Receivership Regulation. On June 20, 2011, the Finance Agency issued a final conservatorship and receivership regulation for the FHLBanks effective July 20, 2011. The final regulation addresses the nature of a conservatorship or receivership and provides greater specificity on their operations, in line with procedures set forth in similar regulatory regimes (for example, the FDIC receivership authorities). The regulation clarifies the relationship among various classes of creditors and equity holders under a conservatorship or receivership and the priorities for contract parties and other claimants in receivership. The Finance Agency explained that its general approach in adopting the final regulation was to set out the basic general framework for conservatorships and receiverships. Under the final regulation:

• Claims of FHLBank members arising from the members' deposit accounts, service agreements, advances, and other transactions with their FHLBanks are distinct from such members' equity claims as holders of FHLBank stock. The final regulation clarifies that the lowest priority position for equity claims only applies to members' claims in regard to their FHLBank stock; the priority position does not apply to claims arising from other member transactions with an FHLBank.

• An FHLBank's claim for repayment/reimbursement in regard to making payment on any COs of another FHLBank in conservatorship or receivership following its default in making such payment would be treated as a general creditor claim against the defaulting FHLBank. The Finance Agency noted in the preamble to the final regulation that it could also address such reimbursement in policy statements or discretionary decisions.

• With respect to property held by an FHLBank in trust or in custodial arrangements, the Finance Agency confirmed that it expects to follow FDIC and bankruptcy practice and such property would not be considered part of a receivership estate and would not be available to satisfy general creditor claims.

Other Banking Regulatory Actions

Proposed Rule on the Financial Stability Oversight Council’s (the Oversight Council’s) Authority to Require Supervision and Regulation of Certain Nonbank Financial Companies. On October 18, 2011, the Oversight Council issued a notice of proposed rulemaking with a comment deadline of December 19, 2011 and guidance regarding the standards and procedures it will follow when it considers whether to designate nonbank financial companies for heightened prudential supervision and oversight by the Federal Reserve Board. This notice rescinded a prior proposal on these designations. Under the proposed designation process, the Oversight Council will first identify those U.S. nonbank financial companies that have $50 billion or more of total consolidated assets and exceed any one of five threshold indicators of interconnectedness or susceptibility to material financial distress. Significantly for the Bank, in addition to the asset size criterion, one of the five thresholds is whether a company has $20 billion or more of borrowing outstanding, including bonds (in the Bank’s case, COs) issued. As of September 30, 2011, the Bank had $48.6 billion in total assets and $43.1 billion in total outstanding COs. If the Bank is designated by the Oversight Council for supervision and oversight by the Federal Reserve Board, then the Bank's operations and business could be adversely impacted by additional costs and business activities' restrictions resulting from such oversight.

102

Banking Agency Revisions to Regulations to Permit Payment of Interest on Demand Deposit Accounts. The Dodd-Frank Act repealed the statutory prohibition against the payment of interest on demand deposits, effective July 21, 2011. To conform their regulations to this provision, the FDIC and other applicable banking regulators have proposed to rescind their regulations prohibiting paying interest on demand deposits effective July 21, 2011. FHLBank members' ability to pay interest on their customers' demand deposit accounts may increase their ability to attract or retain customer deposits which could reduce their funding needs from the FHLBank.

Housing GSE Reform

Housing GSE reform could have significant impacts on the FHLBanks and is discussed under Item 7 — Management's Discussion and Analysis of Financial Condition and Results of Operations — Legislative and Regulatory Developments — Housing Finance and GSE Reform in the 2010 Annual Report. This reform has not progressed significantly to date, but it is expected that efforts to reform the housing GSEs, which could include the FHLBanks, will continue. The FHLBanks could be impacted either directly through legislatively required reforms or indirectly by reforms that impact Fannie Mae and Freddie Mac. However, there is no final housing GSE reform or any other legislation to reform the FHLBanks at this time, and so the impacts of any such legislation cannot be known.

CREDIT RATING AGENCY DEVELOPMENTS

On July 13, 2011, Moody's placed the Aaa bond rating of the U.S. government on review for possible downgrade based on the possibility that U.S. government may not raise the statutory debt limit in time to avoid a default on U.S. Treasury debt obligations. In conjunction with that action, Moody's also placed the Aaa ratings of financial institutions directly linked to the U.S. government on review for possible downgrade, including the FHLBanks. On August 2, 2011, Moody's affirmed the Aaa bond rating of the U.S. government and removed the rating from review for possible downgrade. Moody's has assigned a negative outlook to the rating.
 

On August 8, 2011, S&P downgraded the FHLBanks with long-term credit ratings of AAA at the time, which included the Bank, to AA+ with a negative outlook following S&P's downgrade of the U.S. government's long-term sovereign credit rating from AAA to AA+ with a negative outlook. The U.S. government was downgraded in connection with the debt ceiling debate. S&P has indicated that S&P's credit ratings of select government-related entities, such as the FHLBanks, will be constrained by the credit ratings of the U.S. government. Accordingly, any further downgrade of the U.S. government's credit rating is likely to be followed by a similar downgrade of the FHLBanks. S&P's downgrade and further downgrades to the Bank's credit ratings could adversely impact the Bank's funding costs and/or market access.

In accordance with Congressional agreement on the U.S. government's debt ceiling, a joint (House and Senate) select committee on deficit reduction was convened to form a proposal for a minimum of $1.5 trillion in deficit reduction measures in addition to the deficit reduction measures that have already been agreed to in connection with the agreement. The proposal must be enacted by December 23, 2011, otherwise $1.2 trillion in spending cuts will automatically take effect. However, S&P or other NRSROs could decide to further downgrade the U.S. government (and, in turn, government-related entities, including the FHLBanks) if this process results in weakened perceptions of the U.S. government’s commitment to satisfy its obligations or otherwise falls short of deficit reduction measures that the NRSROs believe are necessary for the U.S. government to retain its current credit ratings.

S&P’s downgrades have impacted and could eventually impact the Bank in several ways, including the following:

• S&P's downgrade of the Bank’s long-term credit rating triggered certain Bank obligations to deliver additional collateral to certain derivatives counterparties to which the Bank is a net obligor, as discussed under —Financial Condition—Derivative Instruments—Derivative Instruments Credit Risk and Item 1 — Notes to Financial Statements — Note 10 — Derivatives and Hedging Activities.

• S&P’s downgrades of the U.S. government’s, certain U.S. GSEs, and certain U.S. government-related entities’s long-term credit ratings could adversely impact the fair value or the liquidity of securities that have been issued or guaranteed by the U.S. government or the downgraded GSEs and government-related entities. The securities that could be impacted in which the Bank invests include U.S. Treasury obligations, corporate debentures guaranteed pursuant to the FDIC's Temporary Liquidity Guarantee Program, and U.S. government guaranteed securities, GSEs, HFA obligations (if the level of Federal Housing Administration-guaranteed mortgage loans in the underlying pool is above a certain threshold) and debentures issued by U.S. government-owned corporations. The aggregate outstanding par value of the securities which could be impacted was $10.7 billion at September 30, 2011, representing approximately 52.1 percent of the par value of the Bank’s investments. During the period covered by this report,

103

however, the Bank has not discerned an impact on the fair values of those securities or their liquidity resulting from S&P’s downgrades.

• S&P’s downgrade of the Bank’s long-term credit rating could weaken or eliminate demand for certain Bank products. Member and housing associate demand for certain of the Bank's products, such as letters of credit and standby bond purchase agreements, is influenced by the Bank's credit ratings and this downgrade or further downgrades of the Bank's credit ratings could weaken or eliminate demand for such products. During the period covered by this report, however, the Bank has not discerned an impact of the S&P downgrade on demand for Bank products.

• S&P’s downgrade of the FHLBanks’ long-term credit ratings could weaken demand for COs and impair market access if some or all investors perceive greater risk of COs or are prohibited from investing in them as a result of the downgrade. During the period covered by this report, however, the Bank has not discerned an impact of the S&P downgrade on the FHLBanks' market access and/or funding costs based on the downgrade.

As of August 8, 2011, S&P's long- and short-term credit ratings for each of the FHLBanks are AA+ and A-1+, with a negative outlook, and Moody's long- and short-term credit ratings for each of the FHLBanks are Aaa and P-1, with a negative outlook.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market and Interest-Rate Risk

Sources and Types of Market and Interest-Rate Risk

The Bank's balance sheet is comprised of different portfolios that require different types of market- and interest-rate-risk management strategies. Sources and types of market and interest-rate risk are described in Item 7A — Quantitative and Qualitative Disclosures About Market Risks in the 2010 Annual Report.

Strategies to Manage Market and Interest-Rate Risk

General

The Bank uses various strategies and techniques to manage its market and interest-rate risk. Principal among its tools for interest-rate-risk management is the issuance of debt that is used to match interest-rate-risk exposures of the Bank's assets. The Bank can issue COs with maturities of up to 30 years (although there is no statutory or regulatory limit on maturities). The debt may be noncallable until maturity or callable on and/or after a certain date.

These bonds may be issued to fund specific assets or to manage the overall exposure of a portfolio or the balance sheet. At September 30, 2011, fixed-rate noncallable debt, not hedged by interest-rate-exchange agreements, amounted to $14.9 billion, compared with $13.6 billion at December 31, 2010. Fixed-rate callable debt, not hedged by interest-rate-exchange agreements, amounted to $648.0 million and $2.7 billion at September 30, 2011, and December 31, 2010, respectively.

To achieve certain risk-management objectives, the Bank also uses interest-rate derivatives that alter the effective maturities, repricing frequencies, or option-related characteristics of financial instruments. These may include swaps, swaptions, caps, collars, and floors; futures and forward contracts; and exchange-traded options. For example, as an alternative to issuing a fixed-rate bond to fund a fixed-rate advance, the Bank might enter into an interest-rate swap that receives a floating-rate coupon and pays a fixed-rate coupon, thereby effectively converting the fixed-rate advance to a floating-rate advance.

Advances

In addition to the general strategies described above, one tool that the Bank uses to reduce the interest-rate risk associated with advances is a contractual provision that requires members to pay prepayment fees for advances that, if prepaid prior to maturity, might expose the Bank to a loss of income under certain interest-rate environments. In accordance with applicable regulations, the Bank has an established policy to charge fees sufficient to make the Bank financially indifferent to a member's decision to repay an advance prior to its maturity. Prepayment fees are recorded as income for the period in which they are received.

Prepayment-fee income can be used to offset the cost of purchasing and retiring high-cost debt to maintain the Bank's asset-liability sensitivity profile. In cases where derivatives are used to hedge prepaid advances, prepayment-fee income can be used to offset the cost of terminating the associated hedge.

104

Investments

The Bank holds certain long-term bonds issued by U.S. federal agencies, U.S. federal government corporations and instrumentalities, HFAs, and supranational banks as available-for-sale. To hedge the market and interest-rate risk associated with these assets, the Bank may enter into interest-rate swaps with matching terms to those of the bonds to create synthetic floating-rate assets. At both September 30, 2011, and December 31, 2010, this portfolio of investments had an amortized cost of $1.1 billion.

The Bank also manages the market and interest-rate risk in its MBS portfolio in several ways. For MBS classified as held-to-maturity, the Bank uses debt that matches the characteristics of the portfolio assets. For example, for floating-rate ABS, the Bank uses debt that reprices on a short-term basis, such as CO discount notes or CO bonds that are swapped to a LIBOR-based floating-rate. For commercial MBS that are nonprepayable or prepayable for a fee for an initial period, the Bank may use fixed-rate debt.

The Bank also manages its interest-rate risk through the selective use of security investments chosen to effect a particular risk- mitigation tactic, principally through the use of the purchase of fixed-rate bullet maturity agency debentures that are funded by issuing debt with a duration generally one year less than the associated security. Deployment of this approach with its initial fixed spread serves as a hedge for the Bank's net interest income against the impact of low interest rates.

The Bank also uses interest-rate swaps to manage the fair-value sensitivity of the portion of its MBS portfolio that is classified as trading securities. These interest-rate-exchange agreements provide an economic offset to the duration and convexity risks arising from these assets.

Mortgage Loans

The Bank manages the interest-rate and prepayment risk associated with mortgage loans through a combination of debt issuance and derivatives. The Bank issues both callable and noncallable debt to achieve cash-flow patterns and liability durations similar to those expected on the mortgage loans.

The Bank mitigates its exposure to changes in interest rates by funding a significant portion of its mortgage portfolio with callable debt. When interest rates change, the Bank's option to redeem this debt offsets a large portion of the fair-value change driven by the mortgage-prepayment option. These bonds are effective in managing prepayment risk by allowing the Bank to respond in kind to prepayment activity. Conversely, if interest rates increase, the debt may remain outstanding until maturity. The Bank uses various cash instruments including shorter-term debt, callable, and noncallable long-term debt to reprice debt when mortgages prepay faster or slower than expected. The Bank's debt-repricing capacity depends on market demand for callable and noncallable debt, which fluctuates from time to time. Additionally, because the mortgage-prepayment option is not fully hedged by callable debt, the combined market value of the Bank's mortgage assets and debt will be affected by changes in interest rates. The Bank may incorporate the use of derivatives if the correlation with mortgage assets is higher than cash instruments. Derivatives provide a flexible, liquid, efficient, and cost-effective method to hedge interest-rate and prepayment risks.

Swapped Consolidated Obligation Debt

The Bank may also issue bonds in conjunction with interest-rate swaps that receive a coupon that offsets the bond coupon and that offsets any optionality embedded in the bond, thereby effectively creating a floating-rate liability. The Bank employs this strategy to secure long-term debt that meets funding needs versus relying on short-term CO discount notes. Total CO bond debt used in conjunction with interest-rate-exchange agreements was $11.3 billion, or 35.3 percent of the Bank's total outstanding CO bonds at September 30, 2011, down from $12.0 billion, or 34.5 percent of total outstanding CO bonds, at December 31, 2010. Because the interest-rate swaps and hedged CO bonds trade in different markets, they are subject to basis risk that is reflected in the Bank's Value at Risk (VaR) calculations and fair-value disclosures, but that is not reflected in hedge ineffectiveness, because these interest-rate swaps are designed to only hedge changes in fair values of the CO bonds that are attributable to changes in the benchmark LIBOR interest rate.

Measurement of Market and Interest-Rate Risk

The Bank measures its exposure to market and interest-rate risk using several techniques applied to the balance sheet and to certain portfolios within the balance sheet. Principal among these measurements as applied to the balance sheet is the potential future change in market value of equity (MVE) and interest income due to potential changes in interest rates, interest-rate volatility, spreads, and market prices. The Bank also measures the duration gap of its assets and liabilities.

105

For a description of the information systems the Bank uses to evaluate its market- and interest-rate risks, see Item 7A —Quantitative and Qualitative Disclosures About Market Risks — Measurement of Market and Interest-Rate Risk in the 2010 Annual Report.

Market Value of Equity Estimation and Market Risk Limit. MVE is the net economic value (or net present value) of total assets and liabilities, including any off-balance-sheet items. In contrast to the GAAP-based shareholder's equity account, MVE represents the shareholder's equity account in present-value terms. Specifically, MVE equals the difference between the theoretical market value of assets and the theoretical market value of liabilities. MVE, and in particular, the ratio of MVE to the book value of equity (BVE), is therefore a theoretical measure of the current value of shareholder investment based on market rates, spreads, prices, and volatility at the reporting date. However, care must be taken to properly interpret the results of the MVE analysis as the theoretical basis for these valuations may not be fully representative of future realized prices. Further, valuations are based on market curves and prices respective of individual assets, liabilities, and derivatives, and therefore are not representative of future net income to be earned by the Bank through the spread between asset market curves and the market curves for funding costs.

For purposes of measuring this ratio, the BVE is equal to the Bank's permanent capital, which consists of the par value of capital stock including mandatorily redeemable capital stock, plus retained earnings. BVE excludes accumulated other comprehensive loss. At September 30, 2011, the Bank's MVE was $3.6 billion and its BVE was $4.1 billion. At December 31, 2010, the Bank's MVE was $3.5 billion and its BVE was $4.0 billion. The Bank's ratio of MVE to BVE was 87.1 percent at September 30, 2011, down slightly from 87.8 percent at December 31, 2010.

The Bank targets a 100 percent ratio between its MVE to the par value of its Class B stock (referred to here as Par Stock), reflecting the Bank's intent to preserve the value of its members' capital investment in the Bank. As of September 30, 2011, that ratio was 94.8 percent, with the shortfall primarily reflecting the ongoing discounted value of the Bank's private-label MBS holdings. The Bank isolates the long-term impact of the depressed prices of its private-label MBS portfolio on its MVE, and has established a limit of 100 percent on the ratio of MVE to Par Stock when the impact of market illiquidity on MVE is removed, referred to as adjusted MVE. Under this measurement, the portion of the discounted price not attributable to credit losses is added back to market value. As of September 30, 2011, the ratio of adjusted MVE to Par Stock was 106.9 percent.

The following chart displays the Bank's MVE to BVE and MVE to Par Stock ratios over the preceding quarters, based on the factors described above.

Interest-rate-risk analysis using MVE involves evaluating the potential changes in fair values of assets and liabilities and off-balance-sheet items under different potential future interest-rate scenarios and determining the potential impact on MVE according to each scenario and the scenario's likelihood. The following table presents the Bank's MVE to BVE and MVE to Par Stock ratios in different interest-rate scenarios.

106

	September 30, 2011			December 31, 2010
	Down(1)	Base	Up(2)	Down(1)	Base	Up(2)
MVE/BVE	88.3%	87.1%	86.0%	92.5%	87.8%	82.8%
MVE/Par Stock	96.0%	94.8%	93.6%	98.6%	93.6%	88.3%

____________________________

(1) Down equals 200 basis points, however, an applicable regulation restricts the down rate from assuming a negative interest rate. Therefore the Bank adjusts the down rate accordingly in periods of very low levels of interest rates.

(2) Up equals 200 basis points.

Value at Risk. VaR measures the change in the Bank's MVE to a 99th percent confidence interval, based on a set of stress scenarios using historical interest-rate and volatility movements that have been observed over six-month intervals starting at the most recent month-end and going back monthly to the beginning of 1978, consistent with Finance Agency regulations.

The table below presents the historical simulation VaR estimate as of September 30, 2011, and December 31, 2010, which represents the estimates of potential reduction to the Bank's MVE from potential future changes in interest rates and other market factors. Estimated potential market value loss exposures are expressed as a percentage of the current MVE and are based on historical behavior of interest rates and other market factors over a 120-business-day time horizon.

	Value-at-Risk (Gain) Loss Exposure
	September 30, 2011					December 31, 2010
Confidence Level	% of MVE (1)		$ million			% of MVE (1)		$ million
50%	(0.07	)%	$	(2.6	)	(0.15	)%	$	(5.4	)
75%	0.37		13.4			0.63		22.2
95%	1.12		40.5			2.27		79.9
99%	1.74		62.8			3.22		113.2

_______________________

(1)Loss exposure is expressed as a percentage of base MVE.

As measured by VaR, the Bank's potential losses to MVE due to changes in interest rates and other market factors decreased to $62.8 million as of September 30, 2011 from $113.2 million as of December 31, 2010. The decrease in VaR since December 31, 2010, resulted from the significant decline in market yields during the quarter ended September 30, 2011, combined with the sales of certain investments with longer maturities and the entering into certain derivatives during the quarter ended June 30, 2011, that were intended to lower VaR.

The Bank's risk-management policy requires that VaR not exceed $275.0 million. Should the limit be exceeded, the policy requires management to notify the board of directors' Risk Committee of such breach and to take steps to reduce the risk exposure. The Bank complied with this limit at all times during the nine months ended September 30, 2011.

Duration of Equity. A further measure of market risk employed by the Bank is its duration of equity. Duration of equity measures the percentage change to shareholder value due to movements in market conditions including, but not limited to, prices, interest rates, and volatility. A positive duration of equity generally indicates an appreciation in shareholder value in times of falling rates and the converse holds true for increasing rate environments. The Bank has established a limit of +/- 5.0 years for duration of equity based on a balanced consideration of market value sensitivity and net interest income sensitivity. The Bank did not exceed its +/- 5.0 year limit in 2011.

Throughout 2010, the Bank took steps to reduce its net interest income exposure to a prolonged period of low market yields, including its deliberate maintenance of positive duration of equity, as described in the 2010 Annual Report under Item 7A — Quantitative and Qualitative Disclosures About Market Risk — Measurement of Market and Interest-Rate Risk. In the second quarter of 2011, the Bank took actions to lower its VaR exposure, as discussed above under -Value at Risk, which also reduced its duration of equity. The latter has remained low subsequently, exacerbated by the significant decline in market yields during the third quarter of 2011. As of September 30, 2011, the Bank's duration of equity was +0.1 years, compared with +1.6 years at December 31, 2010.

107

The following table presents the Bank's duration of equity (in years) in different interest-rate scenarios:

	September 30, 2011			December 31, 2010
	Down(1)	Base	Up(2)	Down(1)	Base	Up(2)
Duration of Equity	1.5	0.1	2.9	2.6	1.6	4.8

____________________________

(1) Down equals 200 basis points; however, an applicable regulation restricts the down rate from assuming a negative interest rate. Therefore the Bank adjusts the down rate accordingly in periods of very low levels of interest rates.

(2) Up equals 200 basis points.

The Bank uses alternative measures of VaR and duration of equity for its private-label MBS, specifically isolating the impact of private-label MBS credit spreads and market illiquidity on the respective metrics. To gauge the impact of potential shifts in interest rates and volatility on the Bank's interest-rate risk exposure, the Bank removes noninterest-rate factors such as the price dislocation and resultant spread-widening attributable to the market illiquidity experienced in 2009 and 2010. These VaR (management VaR) and duration of equity (management duration of equity) measurements are viewed by management as being more representative of the Bank's interest-rate risk profile than those inclusive of current spreads. As of September 30, 2011, management VaR stood at $55.7 million and management duration of equity was (0.2) years. As of December 31, 2010, management VaR stood at $78.4 million and management duration of equity was +1.6 years.

MPF Portfolio Management Action Trigger of 25 Percent of Bank VaR Limit. The Bank has established a management action trigger for VaR exposure from its investments in mortgage loans through the MPF program such that the VaR from these investments shall not exceed 25 percent of the Bank's overall VaR limit. While the Bank seeks to limit interest-rate risk through matching asset maturity and optionality with its corresponding funding, mortgage loans cannot be perfectly match funded due to factors including, but not limited to, borrower prepayment behavior and basis risk between the swap and Bank's funding curves. Accordingly, the Bank maintains this management action trigger, which was $68.8 million at September 30, 2011, based on the Bank's overall VaR limit of $275.0 million. The Bank's actual MPF portfolio VaR exposure at September 30, 2011, was $59.5 million, compared with $54.5 million as of December 31, 2010.

Duration Gap. The Bank measures the duration gap of its assets and liabilities, including all related hedging transactions. Duration gap is the difference between the estimated durations (percentage change in market value for a 100 basis point shift in rates) of assets and liabilities (including the effect of related hedges) and reflects the extent to which estimated sensitivities to market changes, including, but not limited to, maturity and repricing cash flows for assets and liabilities are matched. Higher numbers, whether positive or negative, indicate greater sensitivity in the MVE in response to changing interest rates. A positive duration gap means that the Bank's total assets have an aggregate duration, or sensitivity to interest-rate changes greater than its liabilities, and a negative duration gap means that the Bank's total assets have an aggregate duration shorter than its liabilities. The Bank's duration gap was +0.1 months at September 30, 2011, compared with +1.1 months at December 31, 2010.

Income Simulation and Repricing Gaps. To provide an additional perspective on market and interest-rate risks, the Bank has an income-simulation model that projects net interest income over a range of potential interest-rate scenarios, including parallel interest-rate shocks, nonparallel interest-rate shocks, and nonlinear changes to the Bank's funding curve and LIBOR. The Bank measures simulated 12-month net income and return on equity under these scenarios; the simulations are solely based on simulated movements in the swap and FHLBank funding curves, and do not reflect potential impacts of credit events, including, but not limited to, future other-than-temporary impairment charges. Management has put in place escalation-action triggers whereby senior management is explicitly informed of instances where the Bank's projected return on equity would fall below three-month LIBOR in any of the assumed interest-rate scenarios. The results of this analysis for September 30, 2011, showed that in the worst-case scenario, the Bank's return on equity falls to 143 basis points above the average yield on three-month LIBOR under a yield curve scenario wherein interest rates instantaneously rise by 300 basis points in a parallel fashion across all yield curves; this projected decline in the Bank's return on equity does not reflect the potential impact of future credit losses.

Economic Capital Ratio Limit. The Bank has established a limit of 4.0 percent for the ratio of the MVE to the market value of assets, referred to as the economic capital ratio. Finance Agency regulations require the Bank to maintain a regulatory capital ratio of book capital to book assets limit of no less than 4.0 percent, as discussed in Item 1 — Notes to the Financial Statements — Note 14 — Capital. The Bank seeks to ensure that the regulatory capital ratio will not fall below the 4.0 percent threshold at a future time by establishing the economic capital ratio limit at 4.0 percent. The economic capital ratio serves as a proxy for benchmarking future capital adequacy by discounting the Bank's balance sheet and derivatives at current market expectations of future values. The Bank's economic capital ratio was 7.3 percent as of September 30, 2011, compared with 5.9 percent as of

108

December 31, 2010.

The Bank's economic capital ratio was not below 4.0 percent at any time during the nine months ended September 30, 2011.

ITEM 4.        CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

The Bank's senior management is responsible for establishing and maintaining a system of disclosure controls and procedures designed to ensure that information required to be disclosed by the Bank in the reports filed or submitted under the Securities Exchange Act of 1934 is recorded, processed, summarized, and reported within the time periods specified in the rules and forms of the SEC. The Bank's disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by the Bank in the reports that it files or submits under the Securities Exchange Act of 1934 is accumulated and communicated to the Bank's management, including its principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure. In designing and evaluating the Bank's disclosure controls and procedures, the Bank's management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and the Bank's management necessarily is required to apply its judgment in evaluating the cost-benefit relationship of controls and procedures.

Management of the Bank has evaluated the effectiveness of the design and operation of its disclosure controls and procedures, with the participation of the president and chief executive officer and chief financial officer, as of the end of the period covered by this report. Based on that evaluation, the Bank's president and chief executive officer and chief financial officer have concluded that the Bank's disclosure controls and procedures were effective at a reasonable assurance level as of the end of the fiscal quarter covered by this report.

Changes in Internal Control over Financial Reporting

During the quarter ended September 30, 2011, there were no changes in the Bank's internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, the Bank's internal control over financial reporting.

PART II — OTHER INFORMATION

ITEM 1.    LEGAL PROCEEDINGS

On April 20, 2011, the Bank filed a complaint in the Superior Court Department of the Commonwealth of Massachusetts in Suffolk County, against various securities dealers, underwriters, control persons, issuers/depositors, and credit rating agencies based on the Bank's investments in certain private-label MBS issued by 115 securitization trusts for which the Bank originally paid approximately $5.8 billion. The complaint asserts claims based on untrue or misleading statements in the sale of securities, signing or circulating securities documents that contained material misrepresentations and omissions, negligent misrepresentation, unfair or deceptive trade practices, fraud by the rating agencies, and controlling person liability. The Bank is seeking various forms of relief including rescission, recovery of damages, recovery of purchase consideration plus interest (less income received to date), and recovery of reasonable attorneys' fees and costs of suit.

The complaint names the following defendants and their affiliates and subsidiaries and defendants under their control or controlled by affiliates or subsidiaries thereof: Bank of America Corporation; Barclays Capital Inc.; The Bear Stearns Companies LLC; Capital One Financial Corporation; Citigroup, Inc.; Countrywide Financial Corporation; Credit Suisse (USA), Inc.; DB Structured Products, Inc.; DB U.S. Financial Market Holding Corporation; EMC Mortgage Corporation; GMAC LLC; Fitch, Inc.; Impac Mortgage Holdings, Inc.; JPMorgan Chase & Co.; The McGraw-Hill Companies, Inc.; Moody's Corporation; Morgan Stanley; Nomura Holding America, Inc.; RBS Holdings USA Inc.; Sandler, O'Neill & Partners, L.P.; UBS Americas Inc.; WaMu Capital, Corp.; and Wells Fargo & Company. The complaint also names various individuals due to their association and control over Lehman Brothers Holdings Inc. and its affiliates and subsidiaries and entities controlled by Lehman Brothers Holdings Inc.'s affiliates and subsidiaries in connection with certain of the investments that are the subject of the complaint.

Bank of America Rhode Island, N.A., which is affiliated with Bank of America Corporation but is not a defendant in the complaint, held approximately 28.4 percent of the Bank's capital stock as of September 30, 2011. RBS Citizens N.A., which is affiliated with RBS Holdings USA Inc., but is not a defendant in the complaint, held approximately 13.5 percent of the Bank's capital stock as of September 30, 2011. 

109

Since the time the complaint was filed, the defendants have filed certain notices of removal to remove the case to two different federal courts and effectively sever the complaint into two separate complaints: one that would consist of the claims against the individuals named by the original complaint due to their association with and control over Lehman Brothers Holdings Inc. and its affiliates and subsidiaries; and the other that would consist of all other defendants. The Bank has filed various motions opposing all of these motions, including motions to remand the case to state court.

The Bank from time to time is subject to various pending legal proceedings arising in the normal course of business. After consultation with legal counsel, management does not anticipate that the ultimate liability, if any, arising out of these matters will have a material adverse effect on the Bank's financial condition or results of operations.

Item 1A.    RISK FACTORS

In addition to the risk factors below and other risks described herein, readers should carefully consider the risk factors set forth in the 2010 Annual Report, which could materially impact the Bank's business, financial condition, or future results. The risks described below, elsewhere in this report, and in the 2010 Annual Report are not the only risks facing the Bank. Additional risks and uncertainties not currently known to the Bank or that the Bank currently deems immaterial may also materially impact the Bank.

CREDIT RISKS

The Bank is subject to credit-risk exposures related to the loans that back its investments. Increased delinquency rates and credit losses beyond those currently expected could adversely impact the yield on or value of those investments.

The Bank has invested in HFA securities with an amortized cost of $226.2 million as of September 30, 2011. Generally, these securities' cash flows are based on the performance of the underlying loans, although these securities do include credit enhancements as well. Although the Bank's policies require that HFA bonds must carry a credit rating of double-A (or its equivalent rating) or higher as of the date of purchase, some have since been downgraded and the fair values of some of the Bank's HFA securities have also fallen and the Bank's gross unrealized losses on them totaled $48.4 million at September 30, 2011. As described in the 2010 Annual Report under Item 7 — Management's Discussion and Analysis of Financial Condition and Results of Operations — Critical Accounting Estimates, other-than-temporary-impairment assessment is a subjective and complex determination by management. Although the Bank has determined that none of these securities is other-than-temporarily impaired at September 30, 2011, should the underlying loans underperform the Bank's projections, the Bank could realize credit losses from these securities.

The Bank has also invested in private-label MBS, which are backed by prime, subprime, and/or Alt-A hybrid and pay-option adjustable-rate mortgage loans. Although the Bank only invested in senior tranches with the highest long-term debt rating when purchasing private-label MBS, many of these securities are projected to sustain credit losses under current assumptions, and have been downgraded by various NRSROs. See Part I — Item 2 — Management’s Discussion and Analysis of Financial Condition and Results of Operations — Financial Condition — Investments for a description of the Bank's portfolio of investments in these securities.

Increasing delinquency and loss severity trends experienced on some of the loans underlying the MBS in the Bank's portfolio, as well as challenging macroeconomic factors, such as current unemployment levels and the number of troubled residential mortgage loans, have caused the Bank to use relatively more stressful assumptions than in prior periods for other-than-temporary-impairment assessments of private-label MBS. These assumptions resulted in projected future credit losses, thereby causing other-than-temporary impairment losses from certain of these securities. The Bank incurred credit losses of $7.2 million for private-label MBS that management determined were other-than-temporarily impaired for the three months ended September 30, 2011. If macroeconomic trends or collateral credit performance within the Bank's private-label MBS portfolio deteriorate further than currently anticipated, or if recent foreclosure moratoriums by several major mortgage servicers appear likely to adversely impact expected cash flows from impacted securities, even more stressful assumptions, including, but not limited to, lower house prices, higher loan-default rates, and higher loan-loss severities, may be used by the Bank in future other-than-temporary impairment assessments. As a possible outcome, the Bank may recognize additional other-than-temporary impairment charges, which could be substantial. For example, a cash-flow analysis was also performed for each of these securities under a more stressful housing price scenario. The more stressful scenario was based on a housing price forecast that was five percentage points lower at the trough than the base-case scenario followed by a flatter recovery path. Under this more stressful scenario, the Bank is projected to realize an additional $40.6 million in credit losses.

MARKET RISKS

110

The Federal Reserve's measures intended to maintain low interest rates could adversely impact the Bank's financial condition and results of operations.

As discussed under Part I — Item 2 — Management's Discussion and Analysis of Financial Condition and Results of Operations — Executive Summary, the Federal Reserve has taken several measures intended to maintain low short-term and longer- term interest rates. These measures as well as other systemic events, such as the European sovereign debt crisis, could result in a prolonged low-interest rate environment. A prolonged low-interest rate environment could adversely impact the Bank in various ways, including through lower market yields on investments and faster prepayments on Bank investments with associated reinvestment risk. The Bank's investment income and, in turn, the Bank's financial condition and results of operations, could be adversely impacted to the extent that the foregoing, or similar, risks are realized without being offset by the anticipated beneficial impacts of these measures.

The Bank's funding costs and/or access to the capital markets and demand for certain Bank products could be adversely impacted by S&P's downgrade of the U.S. government's credit ratings and/or any further downgrade of the U.S. government's credit ratings.

As discussed under Part I — Item 2 — Management's Discussion and Analysis of Financial Condition and Results of Operations - Credit Rating Agency Developments, S&P has downgraded the Bank's long-term credit rating to AA+ with a negative outlook. S&P has indicated that any further downgrade of the U.S. government's credit rating is likely to be followed by a similar downgrade of the FHLBanks. Further downgrades of the U.S. government (and, in turn, the FHLBanks) are possible, particularly if the process of identifying deficit reduction measures results in weakened perceptions of the U.S. government's commitment to satisfy its obligations or otherwise falls short of the deficit reduction measures that the NRSROs believe are necessary for the U.S. government to retain its current credit ratings. S&P's downgrade and further downgrades to the Bank's credit ratings could adversely impact the Bank's funding costs and/or market access. Additionally, S&P's downgrade triggered certain Bank obligations to deliver additional collateral to certain derivatives counterparties to which the Bank is a net obligor. Further downgrades would trigger Bank obligations to deliver additional collateral under such derivatives, as discussed under Part I — Item 1 — Notes to the Financial Statements — Note 10 — Derivatives and Hedging Activities and Part I — Item 2 — Management's Discussion and Analysis of Financial Condition and Results of Operations — Financial Condition — Derivative Instruments — Derivative Instruments Credit Risk. Further, member and housing associate demand for certain of the Bank's products, such as letters of credit and standby bond purchase agreements, is influenced by the Bank's credit ratings and this downgrade or further downgrades of the Bank's credit ratings could weaken or eliminate demand for such products. To the extent that the Bank cannot access funding when needed on acceptable terms to effectively manage its cost of funds or demand for the Bank's products falls, the Bank's financial condition and results of operations could be adversely impacted.

OPERATIONAL RISKS

The Bank relies heavily upon information systems and other technology and any disruption or failure of such information systems or other technology could adversely impact the Bank's reputation, financial condition and results of operations.

As discussed under Part I — Item 2 — Management's Discussion and Analysis of Financial Condition and Results of Operations — Risk Management — Operational Risk, the Bank is subject to operational risk. The Bank has not experienced a disruption in its information systems or other technology that has had a material adverse impact on the Bank. However, the Bank relies heavily on its information systems and other technology to conduct and manage its business and so failures or interruptions of these information systems or other technology could have a material adverse impact on the Bank's financial condition and results of operations. Additionally, most of the Bank's information systems have been co-located with a third party service provider on whom the Bank is reliant to provide a secure location and a stable operating environment for these systems. Any failure to provide such stability or security by the third party service provider could result in failures or interruptions in the Bank's ability to conduct business. Further, the Bank's AHP and MPF investment activities rely on the secure processing, storage, and transmission of a large volume of private borrower information, such as names, residential addresses, social security numbers, credit rating data, and other consumer financial information. This information could be exposed in several ways, including through unauthorized access to the Bank's computer systems, computer viruses that attack the Bank's computer systems, software or networks, accidental delivery of information to an unauthorized party, and loss of encrypted media containing this information. Any of these events could result in financial losses, legal and regulatory sanctions, and reputational damage.

Fair-Value Methodologies and Techniques

The fair-value amounts above have been determined by the Bank using available market information and the Bank's best judgment of appropriate valuation methods. These estimates are based on pertinent information available to the Bank at September 30, 2011, and December 31, 2010. Although the Bank uses its best judgment in estimating the fair value of these financial instruments, there are inherent limitations in any estimation technique or valuation methodology. For example, because an active secondary market does not exist for a portion of the Bank's financial instruments, in certain cases, fair values are not subject to precise quantification or verification and may change as economic and market factors and evaluation of those factors change. Therefore, these fair values are not necessarily indicative of the amounts that would be realized in current market transactions, although they do reflect the Bank's judgment of how a market participant would estimate the fair values. The fair-value summary table above does not represent an estimate of the overall market value of the Bank as a going concern, which would take into account future business opportunities and the net profitability of assets versus liabilities.

Cash and Due from Banks. The fair value approximates the recorded carrying value.

Interest-Bearing Deposits. The fair value is determined by calculating the present value of expected future cash flows. The discount rates used in these calculations are the rates for interest-bearing deposits with similar terms.

Investment Securities. For investment securities other than HFA floating-rate obligations, the Bank requests prices from four specific third-party vendors, and, depending on the number of prices received for each security, selects a median or average price as defined by the methodology. The methodology also incorporates variance thresholds to assist in identifying median or average prices that may require further review. In certain limited instances (for example, prices are outside of variance thresholds or the third-party services do not provide a price), the Bank will obtain a price from securities dealers or internally model a price that is deemed most appropriate after consideration of all relevant facts and circumstances that would be considered by market participants. In obtaining such valuation information from third parties, the Bank generally reviews the valuation methodologies used to develop the fair values to determine whether such valuations are representative of an exit price in the Bank's principal markets.

Investment Securities – Housing-Finance-Agency Floating-Rate Obligations. The fair value isdetermined by calculating the present value of the expected future cash flows. The discount rates used in these calculations are the rates for securities with similar terms.

Securities Purchased under Agreements to Resell. The fair value is determined by calculating the present value of expected future cash flows. The discount rates used in these calculations are the rates for transactions with similar terms.

Federal Funds Sold. The fair value is determined by calculating the present value of the expected future cash flows. The discount rates used in these calculations are the rates for federal funds sold with similar terms.

Advances. The Bank determines the fair value of advances by calculating the present value of expected future cash flows from the advances and excluding the amount of accrued interest receivable. The discount rates used in these calculations are the current replacement rates for advances with similar terms. In accordance with the Finance Agency's advances regulations, advances with a maturity or repricing period greater than six months require a prepayment fee sufficient to make the Bank financially indifferent to the borrower's decision to prepay the advances. Therefore, the fair value of advances does not assume prepayment risk. The Bank does not account for credit risk in determining the fair value of the Bank's advances due to the strong credit protections that mitigate the credit risk associated with advances. Collateral requirements for advances provide surety for the repayment such that the probability of credit losses on advances is very low. The Bank has the ability to establish a blanket lien on all financial assets of most members, and in the case of federally-insured depository institutions, the Bank’s lien has a statutory priority over all other creditors with respect to collateral that has not been perfected by other parties. All of these factors serve to mitigate credit risk on advances.

Mortgage Loans. The fair values for mortgage loans are determined based on quoted market prices of similar mortgage-loan pools available in the market or modeled prices adjusted for factors specific to the Bank's mortgage loans including, but not limited to, differences in coupon, average loan rate, seasoning, and cash-flow remittance between the Bank's mortgage loans and the MBS. The prices of the referenced MBS and the mortgage loans are highly dependent upon the underlying prepayment assumptions priced in the secondary market. Changes in the prepayment rates could have a material effect on the fair value. Since these underlying prepayment assumptions are made at a specific point in time, they are susceptible to material changes in the near term.

Real Estate Owned. Fair value is defined as the amount that a willing seller could expect from a willing buyer in an arm's-length transaction. If the fair value of the REO is less than the recorded investment in the MPF loan at the date of transfer, the Bank recognizes a charge-off to the allowance for credit losses. Subsequent realized gains and realized or unrealized losses are included in other income (loss) in the statement of operations.

Accrued Interest Receivable and Payable. The fair value is the recorded book value.

Derivative Assets/Liabilities – Interest-Rate-Exchange Agreements. The Bank bases the fair values of interest-rate-exchange agreements on available market prices of derivatives having similar terms, including accrued interest receivable and payable. The fair value is based on the LIBOR swap curve and forward rates at period-end and, for agreements containing options, the market's expectations of future interest-rate volatility implied from current market prices of similar options. The fair value methodology uses standard valuation techniques for derivatives such as discounted cash-flow analysis and comparisons with similar instruments. The fair values are netted by counterparty, including cash collateral received from or delivered to the counterparty, where an offset right exists. If these netted amounts are positive, they are classified as an asset, and if negative, they are classified as a liability. The Bank enters into master-netting agreements for interest-rate-exchange agreements with institutions that have long-term senior unsecured credit ratings that are at or above single-A by S&P and Moody's. The Bank establishes master-netting agreements to reduce its exposure from counterparty defaults, and enters into bilateral-collateral-exchange agreements that require credit exposures beyond a defined amount to be secured by U.S. government or GSE securities or cash. All of these factors serve to mitigate credit and nonperformance risk to the Bank.

Derivative Assets/Liabilities – Commitments to Invest in Mortgage Loans.Commitments to invest in mortgage loans are recorded as derivatives in the statement of condition. The fair values of such commitments are based on the end-of-day delivery commitment prices provided by the FHLBank of Chicago, which are derived from MBS to be announced (TBA) delivery commitment prices with adjustment for the contractual features of the MPF program, such as servicing and credit-enhancement features.

Deposits. The Bank determines fair values of deposits by calculating the present value of expected future cash flows from the deposits and reducing this amount by any accrued interest payable. The discount rates used in these calculations are the cost of deposits with similar terms.

Consolidated Obligations. The Bank estimates fair values based on the cost of issuing comparable term debt, excluding noninterest selling costs. Fair values of COs without embedded options are determined based on internal valuation models which use market-based yield curve inputs obtained from the Office of Finance (the FHLBanks' agent that issues and services the Banks' COs). Fair values of COs with embedded options are determined based on internal valuation models with market-based inputs obtained from the Office of Finance and derivative dealers.

Mandatorily Redeemable Capital Stock. The fair value of capital stock subject to mandatory redemption is generally at par. Capital stock can only be acquired by the Bank's members at par value and redeemed at par value. The Bank's capital stock is not traded and no market mechanism exists for the exchange of capital stock outside the cooperative structure.

Commitments. The fair value of the Bank's standby bond-purchase agreements is based on the present value of the estimated fees the Bank is to receive for providing these agreements, taking into account the remaining terms of such agreements. For fixed-rate advance commitments, fair value also considers the difference between current levels of interest rates and the committed rates.

Estimates of the fair value of advances with options, mortgage instruments, derivatives with embedded options, and CO bonds with options are highly subjective and require judgments regarding significant matters such as the amount and timing of future cash flows, prepayment speed assumptions, expected interest-rate volatility, methods to determine possible distributions of future interest rates used to value options, and the selection of discount rates that appropriately reflect market and credit risks. Changes in these judgments often have a material effect on the fair-value estimates. Since these estimates are made as of a specific point in time, they are susceptible to material near-term changes.

Fair-Value Hierarchy. The Bank records trading securities, available-for-sale securities, derivative assets, and derivative liabilities at fair value. The transaction to sell the asset or transfer the liability is a hypothetical transaction at the measurement date, considered from the perspective of a market participant that holds the asset or owes the liability. In general, the transaction price will equal the exit price and, therefore, represents the fair value of the asset or liability at initial recognition. In determining whether a transaction price represents the fair value of the asset or liability at initial recognition, each reporting entity is required to consider factors specific to the asset or liability, the principal or most advantageous market for the asset or liability, and market participants with whom the entity would transact in that market.

The fair-value hierarchy prioritizes the inputs of valuation techniques used to measure fair value. The inputs are evaluated and an overall level within the fair-value hierarchy for the fair-value measurement is determined. This overall level is an indication of the market observability of the fair-value measurement. Fair value is the price in an orderly transaction between market participants to sell an asset or transfer a liability in the principal (or most advantageous) market for the asset or liability at the measurement date (an exit price). To determine the fair value or the exit price, entities must determine the unit of account, highest and best use, principal market, and market participants. These determinations allow the reporting entity to define the inputs for fair value and level within the fair-value hierarchy.

Outlined below is the application of the fair-value hierarchy to the Bank's financial assets and financial liabilities that are carried at fair value.

Level 1Defined as those instruments for which inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets. An active market for the asset or liability is a market in which the transactions for the asset or liability occur with sufficient frequency and volume to provide pricing information on an ongoing basis. The types of assets and liabilities carried at Level 1 fair value generally include certain types of derivative contracts that are traded in an open exchange market and investments such as U.S. Department of the Treasury (U.S. Treasury) securities.

Level 2Defined as those instruments for which inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument. The types of assets and liabilities carried at Level 2 fair value generally include investment securities, including U.S. government and agency securities, and derivative contracts.

Level 3Defined as those instruments for which inputs to the valuation methodology are unobservable and significant to the fair-value measurement. Unobservable inputs are supported by little or no market activity and reflect the Bank's own assumptions. The types of assets and liabilities carried at Level 3 fair value generally include certain private-label MBS.

The Bank uses valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. Fair value is first determined based on quoted market prices or market-based prices, where available. If quoted market prices or market-based prices are not available, fair value is determined based on valuation models that use market-based information available to the Bank as inputs to the models.

For instruments carried at fair value, the Bank reviews the fair-value hierarchy classifications on a quarterly basis. Changes in the observability of the valuation attributes may result in a reclassification of certain financial assets or liabilities, and those reclassifications will be reported as a transfer between levels at fair value in the quarter in which the change occurs. Transfers between levels will be reported as of the beginning of the period; however the Bank did not have any transfers between levels during the nine months ended September 30, 2011.

Fair Value on a Nonrecurring Basis

The Bank measures certain held-to-maturity investment securities and REO at fair value on a nonrecurring basis; that is, they are not measured at fair value on an ongoing basis but are subject to fair-value adjustments only in certain circumstances (for example, upon recognizing an other-than-temporary impairment on a held-to-maturity security).

The following tables present the fair value of financial assets by level within the fair value hierarchy which are recorded on a nonrecurring basis at September 30, 2011, and December 31, 2010 (dollars in thousands).

Significant Inputs of Recurring and Nonrecurring Fair-Value Measurements

The following represents the significant inputs used to determine fair value of those instruments carried on the balance sheet at fair value which are classified as Level 2 or Level 3 within the fair-value hierarchy. The descriptions below do not differentiate between recurring and nonrecurring fair-value measurements and should be read in conjunction with the fair-value methodology disclosures for all financial instruments provided above.

Investment Securities. For the Bank's investment securities carried at fair value the Bank's valuation technique incorporates prices from up to four designated third-party pricing vendors when available, consistent with the method agreed upon by the FHLBanks. These pricing vendors use methods that generally employ, but are not limited to, benchmark yields, recent trades, dealer estimates, valuation models, benchmarking of like securities, sector groupings, and/or matrix pricing. The Bank establishes a price for each of its investment securities using a formula that is based upon the number of prices received.

The computed prices are tested for reasonableness using specified tolerance thresholds. Prices within the established thresholds are generally accepted unless strong evidence suggests that using the formula-driven price would not be appropriate. Preliminary estimated fair values that are outside the tolerance thresholds, or that management believes may not be appropriate based on all available information (including those limited instances in which only one price is received), are subject to further analysis including, but not limited to, a comparison with the prices for similar securities and/or to nonbinding dealer estimates or use of an internal model that is deemed most appropriate after consideration of all relevant facts and circumstances that a market participant would consider. As of September 30, 2011, vendor prices were received for substantially all of the FHLBanks' investment securities and all of those prices fell within the specified thresholds. The relative proximity of the prices received supports the Bank's conclusion that the final computed prices are reasonable estimates of fair value. Based on the current lack of significant market activity for private-label residential MBS, the nonrecurring fair-value measurements for such securities as of September 30, 2011, fell within Level 3 of the fair-value hierarchy. 

REO. For the Bank's REO the fair value is derived from third party valuations of the property.

Derivative Assets/Liabilities. Fair value of derivatives is generally determined using discounted cash-flow analysis (the income approach) and comparisons with similar instruments (the market approach). The discounted cash-flow model uses market-observable inputs (inputs that are actively quoted and can be validated to external sources). Inputs by class of derivative are as follows:

Interest-rate-exchange agreements:

• LIBOR swap curve; and

• Market-based expectations of future interest-rate volatility implied from current market prices for similar options for agreements containing options.

Mortgage delivery commitments:

• MBS TBA price. Market-based prices of TBAs are determined by coupon class and expected term until settlement.

The Bank generally uses a midmarket pricing convention as a practical expedient for fair-value measurements within a bid-ask spread. Because these estimates are made at a specific point in time, they are susceptible to material near-term changes.

Transactions with Other FHLBanks [Abstract]

Transactions with Other FHLBanks [Text Block]

Transactions with Other FHLBanks

The Bank may occasionally enter into transactions with other FHLBanks. These transactions are summarized below.

Overnight Funds. The Bank may borrow or lend unsecured overnight funds from or to other FHLBanks. All such transactions are at current market rates. Interest income and interest expense related to these transactions with other FHLBanks are included within other interest income and interest expense from other borrowings in the statement of operations.

MPF Mortgage Loans. The Bank pays a transaction-services fee to the FHLBank of Chicago for the Bank’s participation in the MPF program. This fee is assessed monthly, and is based upon the amount of MPF loans in which the Bank invested after January 1, 2004, and which remain outstanding on the Bank’s statement of condition. The Bank recorded $285,000 and $262,000 in MPF transaction-services fee expense to the FHLBank of Chicago during the three months ended September 30, 2011 and 2010, respectively, which has been recorded in the statement of operations as other expense. The Bank recorded $843,000 and $786,000 in MPF transaction-services fee expense to the FHLBank of Chicago during the nine months ended September 30, 2011 and 2010, respectively, which has been recorded in the statement of operations as other expense.

Other-Than-Temporary Impairment

9 Months Ended

Sep. 30, 2011

Other Than Temporary Impairment [Abstract]

Other-than-Temporary Impairment, Credit Losses Recognized in Earnings Disclosure [Text Block]

Other-Than-Temporary Impairment

The Bank evaluates its individual available-for-sale and held-to-maturity securities for other-than-temporary impairment on a quarterly basis. As part of its evaluation of securities for other-than-temporary impairment, the Bank considers its intent to sell each debt security or whether it is more likely than not that the Bank will be required to sell the security before the anticipated recovery of the remaining amortized cost. If either of these conditions is met, the Bank recognizes an other-than-temporary impairment charge in earnings equal to the entire difference between the security's amortized cost basis and its fair value at the balance-sheet date. For securities that meet neither of these conditions and for all residential private-label MBS, the Bank performs additional analysis to determine if any of these securities are other-than-temporarily impaired.

Available-for-Sale Securities

As a result of these evaluations, the Bank determined that none of its available-for-sale securities were other-than-temporarily impaired at September 30, 2011. The Bank's available-for-sale securities portfolio has experienced unrealized losses that reflect the impact of normal yield and spread fluctuations attendant with security markets. However, the declines are considered temporary as the Bank expects to recover the entire amortized cost basis on these available-for-sale securities in an unrealized loss position and neither intends to sell these securities nor is it more likely than not that the Bank will be required to sell these securities before the anticipated recovery of each security's remaining amortized cost basis. Regarding securities that were in an unrealized loss position as of September 30, 2011:

• Debentures issued by a supranational bank that were in an unrealized loss position as of September 30, 2011, are expected to return contractual principal and interest, based on the Bank's review and analysis of independent third-party credit reports on the supranational entity, and such supranational entity is rated triple-A by each of the nationally recognized statistical rating organizations (NRSROs).

• Debentures issued by U.S. government corporations are not obligations of the U.S. government and not guaranteed by the U.S. government. However, these securities are rated at the same level as the U.S. government by the NRSROs. These ratings reflect the U.S. government's implicit support of the government corporation as well as the entity's underlying business and financial risk.

• The Bank has concluded that the probability of default on debt issued by the Federal National Mortgage Association (Fannie Mae) and the Federal Home Loan Mortgage Corporation (Freddie Mac) is remote given their status as GSEs and their support from the U.S. government. Further, MBS issued by Fannie Mae and Freddie Mac, which we sometimes refer to as agency MBS in this report, are backed by mortgage loans conforming with those GSEs' underwriting requirements and the GSEs' credit guarantees as to full return of principal and interest.

Held-to-Maturity Securities

State or Local Housing-Finance-Agency Obligations. Management has reviewed the state and local housing-finance-agency (HFA) obligations and has determined that unrealized losses reflect the impact of normal market yield and spread fluctuations and illiquidity in the credit markets. The Bank has determined that all unrealized losses are temporary given the creditworthiness of the issuers and the underlying collateral, including an assessment of past payment history, property vacancy rates, debt service ratios, overcollateralization, and third-party bond insurance as applicable. As of September 30, 2011, none of the Bank's held-to-maturity investments in HFA obligations were rated below investment grade by an NRSRO. Because the decline in market value is attributable to changes in interest rates and credit spreads and illiquidity in the credit markets and not to a significant deterioration in the fundamental credit quality of these obligations, and because the Bank does not intend to sell the investments nor is it more likely than not that the Bank will be required to sell the investments before recovery of the amortized cost basis, the Bank does not consider these investments to be other-than-temporarily impaired at September 30, 2011.

Agency MBS. For agency MBS, the Bank determined that the strength of the issuers' guarantees through direct obligation or support from the U.S. government is sufficient to protect the Bank from losses based on current expectations. As a result, the Bank has determined that, as of September 30, 2011, all of the gross unrealized losses on such MBS are temporary. The Bank does not believe that the declines in market value of these securities are attributable to credit quality, and because the Bank does not intend to sell the investments, nor is it more likely than not that the Bank will be required to sell the investments before recovery of the amortized cost basis, the Bank does not consider any of these investments to be other-than-temporarily impaired at September 30, 2011.

Private-Label Residential MBS and ABS Backed by Home Equity Loans. The Bank invested in private-label residential MBS, which as of the date of purchase were all rated triple-A. Each private-label residential MBS may contain one or more forms of credit protection/enhancements, including, but not limited to, guarantee of principal and interest, subordination, over-collateralization and excess interest, and third-party bond insurance.

To ensure consistency in determination of the other-than-temporary impairment for private-label residential MBS and certain home equity loan investments (including home equity ABS) among all Federal Home Loan Banks (the FHLBanks or the FHLBank System), the FHLBanks enhanced their overall other-than-temporary impairment process in 2009 by implementing a Systemwide governance committee (the OTTI Governance Committee) and establishing a formal process to ensure consistency in key other-than-temporary impairment modeling assumptions used for purposes of their cash-flow analyses for the majority of these securities. The Bank uses the FHLBanks' common framework and approved assumptions for purposes of its other-than-temporary impairment cash-flow analysis on its private-label residential MBS and certain home equity loan investments. For certain private-label residential MBS and home equity loan investments where underlying collateral data is not available, the Bank has used alternative procedures to assess these securities for other-than-temporary impairment. The Bank is responsible for making its own determination of impairment and the reasonableness of assumptions, inputs, and methodologies used and for performing the required present value calculations using appropriate historical cost bases and yields.

The Bank's evaluation includes estimating the projected cash flows that the Bank is likely to collect based on an assessment of all available information, including the structure of the applicable security and certain assumptions to determine whether the Bank will recover the entire amortized cost basis of the security, such as:

• the remaining payment terms for the security;

• prepayment speeds;

• default rates;

• loss severity on the collateral supporting each security based on underlying loan-level borrower and loan characteristics;

• expected housing price changes; and

• interest-rate assumptions.

In performing a detailed cash-flow analysis, the Bank identifies the best estimate of the cash flows expected to be collected. If this estimate results in a present value of expected cash flows (discounted at the security's effective yield) that is less than the amortized cost basis of a security (that is, a credit loss exists), other-than-temporary impairment is considered to have occurred. For determining the present value of variable-rate and hybrid private-label residential MBS, the Bank uses the effective interest rate derived from a variable-rate index such as one-month London Interbank Offered Rate (LIBOR) plus the contractual spread, plus or minus a fixed-spread adjustment when there is an existing discount or premium on the security. As the implied forward curve of the index changes over time, the effective interest rates derived from that index will also change over time.

In accordance with related guidance from the Federal Housing Finance Agency (Finance Agency), the Bank has contracted with the FHLBanks of San Francisco and Chicago to perform the cash-flow analysis underlying the Bank's other-than-temporary impairment decisions in certain instances. In the event that neither the FHLBank of San Francisco nor the FHLBank of Chicago has the ability to model a particular MBS owned by the Bank, the Bank projects the expected cash flows for that security based on the Bank's expectations as to how the underlying collateral and impact on deal structure resultant from collateral cash flows are forecasted to occur over time. These assumptions are based on factors including, but not limited to loan-level data for each security and modeling variables expectations for securities similar in nature modeled by either the FHLBank of San Francisco or the FHLBank of Chicago. The Bank forms these expectations for those securities by reviewing, when available, loan-level data for each such security, and, when such loan-level data is not available for a security, by reviewing loan-level data for similar loan pools as a proxy for such data.

Specifically, the Bank has contracted with the FHLBank of San Francisco to perform cash-flow analyses for its residential private-label MBS other than subprime private-label MBS, and with the FHLBank of Chicago to perform cash-flow analyses for its subprime private-label MBS. The following table summarizes the analyses of the FHLBanks contracted to perform cash-flow analysis for the Bank (dollars in thousands).

	September 30, 2011
	Number of Securities	Par Value		Amortized Cost		Carrying Value		Fair Value
FHLBank of San Francisco	170	$	2,502,362	$	1,972,072	$	1,533,803	$	1,450,488
FHLBank of Chicago	16	$	24,059	$	23,333	$	22,034	$	17,768
Bank's own cash-flow projections	13	$	79,054	$	64,298	$	49,141	$	42,495

To assess whether the entire amortized cost basis of private-label residential MBS will be recovered, cash-flow analyses for each of the Bank's private-label residential MBS were performed. These analyses use two third-party models.

The first third-party model considers borrower characteristics and the particular attributes of the loans underlying the Bank's securities, in conjunction with the assumptions about future changes in home prices and interest rates, and projects prepayments, defaults, and loss severities. A significant input to the first model is the forecast of future housing-price changes for the relevant states and core-based statistical areas (CBSAs), which are based upon an assessment of the individual housing markets. The term CBSA refers collectively to metropolitan and micropolitan statistical areas as defined by the United States Office of Management and Budget; as currently defined, a CBSA must contain at least one urban area of 10,000 or more people. The Bank's housing-price forecast as of September 30, 2011, assumed current-to-trough home price declines ranging from 0.0 percent (for those housing markets that are believed to have reached their trough) to 10.0 percent. For those markets for which further home price declines are anticipated, such declines were projected to occur over the three- to nine-month period beginning July 1, 2011. From the trough, home prices were projected to recover using one of five different recovery paths that vary by housing market. Under those recovery paths, home prices were projected to increase as follows:

	Range %
Year 1	0.0	—	2.8
Year 2	0.0	—	3.0
Year 3	1.5	—	4.0
Year 4	2.0	—	5.0
Years 5 and 6	2.0	—	6.0
Thereafter	2.3	—	5.6

The month-by-month projections of future loan performance are derived from the first model to determine projected prepayments, defaults, and loss severities. These projections are then input into a second model that calculates the projected loan-level cash flows and then allocates those cash flows and losses to the various classes in the securitization structure in accordance with the cash-flow and loss-allocation rules prescribed by the securitization structure.

The Bank does not intend to sell these securities and believes it is not more likely than not that the Bank will be required to sell these securities before the anticipated recovery of each security's remaining amortized cost basis. The Bank recorded other-than-temporary impairment credit losses of $7.2 million for the three months ended September 30, 2011. For held-to-maturity securities, the noncredit portion of an other-than-temporary impairment charge that is recognized in other comprehensive loss is accreted from accumulated other comprehensive loss to the carrying value of the security over the remaining life of the security in a prospective manner based on the amount and timing of future estimated cash flows. This accretion continues until the security is sold or matures, or an additional other-than-temporary impairment charge is recorded in earnings, which could result in a reclassification adjustment and the establishment of a new amount to be accreted. For the three months ended September 30, 2011, the Bank accreted $35.3 million of noncredit impairment from accumulated other comprehensive loss to the carrying value of held-to-maturity securities. For certain other-than-temporarily impaired securities that were previously impaired and have subsequently incurred additional credit losses during the three months ended September 30, 2011, the additional credit losses, up to the amount in accumulated other comprehensive loss, were reclassified out of noncredit-related losses in accumulated other comprehensive loss and charged to earnings. This amount was $4.1 million for the three months ended September 30, 2011.

For those securities for which an other-than-temporary impairment was determined to have occurred during the quarter ended September 30, 2011 (that is, a determination was made that less than the entire amortized cost basis is expected to be recovered), the following table presents a summary of the average projected values over the remaining lives of the securities for the significant inputs used to measure the amount of the credit loss recognized in earnings during the three months ended September 30, 2011, as well as related current credit enhancement. Credit enhancement is defined as the percentage of subordinated tranches and over-collateralization, if any, in a security structure that will generally absorb losses before the Bank will experience a loss on the security. The calculated averages represent the dollar-weighted averages of all the private-label residential MBS and home equity loan investments in each category shown (dollars in thousands).

_______________________

(1)Securities are classified in the table above based upon the current performance characteristics of the underlying loan pool and therefore the manner in which the loan pool backing the security has been modeled (as prime, Alt-A, or subprime), rather than the classification of the security at the time of issuance.

Certain private-label MBS owned by the Bank are insured by third-party bond insurers (monoline insurers). The FHLBanks performed analyses to assess the financial strength of these monoline insurers to establish an expected case regarding the time horizon of the bond insurers' ability to fulfill their financial obligations and provide credit support. The projected time horizon of credit protection provided by an insurer is a function of claims-paying resources and anticipated claims in the future. This assumption is referred to as the “burnout period” and is expressed in months. Of the five monoline insurers, the financial guarantee from Assured Guaranty Municipal Corp. is considered sufficient to cover all future claims and is, therefore, excluded from the burnout analysis discussed above. Conversely, the burnout period for three monoline insurers, Syncora Guarantee Inc., Financial Guarantee Insurance Corp., and Ambac Assurance Corp. (Ambac), are not considered applicable due to regulatory intervention that has generally suspended all claims payments to effectively zero. For the remaining monoline insurer, MBIA Insurance Corp. (MBIA), the burnout period as of September 30, 2011, is three months, ending December 31, 2011. No securities guaranteed by MBIA were determined to have an other-than-temporary impairment credit loss at September 30, 2011.

Recently Issued Accounting Standards and Interpretations

Recently Issued Accounting Standards and Interpretations [Abstract]

Description of New Accounting Pronouncements Not yet Adopted [Text Block]

Recently Issued Accounting Standards and Interpretations

Disclosures about an Employer’s Participation in a Multiemployer Plan. On September 21, 2011, the Financial Accounting Standards Board (the FASB) issued guidance intended to enhance disclosures about an employer's participation in a multiemployer pension plan. These disclosures are intended to provide users with the following: (1) additional administrative information about an employer's participation in significant multiemployer plans; (2) an employer's participation level in these plans, including contributions made and whether contributions exceed five percent of total contributions made to a plan; (3) the financial health of these plans, including information about funded status and funding improvement plans, as applicable; and (4) the nature of employer commitments to the plan, including expiration dates of collective bargaining agreements and whether such agreements require minimum plan contributions. Previously, disclosures were limited primarily to the historical contributions made to all multiemployer pension plans. The new disclosures are required for annual periods ending December 31, 2011, and will be applied retrospectively for all prior periods presented. The adoption of this amended guidance is likely to result in increased annual financial statement disclosures, but will not affect the Bank's financial condition, results of operations, or cash flows.

Presentation of Comprehensive Income. On June 16, 2011, the FASB issued guidance to increase the prominence of other comprehensive income in financial statements. This guidance requires an entity that reports items of other comprehensive income to present comprehensive income in either a single financial statement or in two consecutive financial statements. In a single continuous statement, an entity is required to present the components of net income and total net income, the components of other comprehensive income, and a total for other comprehensive income, as well as a total for comprehensive income. In a two-statement approach, an entity is required to present the components of net income and total net income in its statement of net income. The statement of other comprehensive income should follow immediately and include the components of other comprehensive income as well as totals for both other comprehensive income and comprehensive income. This guidance eliminates the option to present other comprehensive income in the statement of changes in stockholders' equity. This guidance is effective for the Bank for interim and annual periods beginning on January 1, 2012, and will be applied retrospectively for all periods presented. Early adoption is permitted. The Bank plans to elect the two-statement approach noted above beginning on January 1, 2012. The adoption of this guidance is expected to be limited to the presentation of its annual and interim financial statements and not affect the Bank's financial condition, results of operations, and cash flows.

On October 21, 2011, the FASB voted to propose a deferral of the new requirement to present reclassifications of other comprehensive income in the income statement. Entities would still be required to adopt the other guidance contained in the new accounting standard for the presentation of comprehensive income.

Common Fair Value Measurement and Disclosure Requirements in GAAP and International Financial Reporting Standards (IFRS). On May 12, 2011, the FASB and the International Accounting Standards Board both issued new guidance that results in a consistent definition of fair value and common requirements for measurement of and disclosures about fair value between GAAP and IFRS. While many of the amendments to GAAP are not expected to have a significant effect on practice, the new guidance changes some fair value measurement principles and disclosure requirements currently in GAAP. The new guidance goes into effect on January 1, 2012, for the Bank and will be applied prospectively. The Bank is currently evaluating the effect of the adoption of this guidance on the Bank's financial condition, results of operations, and cash flows.

Reconsideration of Effective Control for Repurchase Agreements. On April 29, 2011, the FASB issued guidance to improve the accounting for repurchase agreements and other agreements that both entitle and obligate a transferor to repurchase or redeem financial assets before their maturity. This guidance amends the existing criteria for determining whether or not a transferor has retained effective control over financial assets transferred under a repurchase agreement. A secured borrowing is recorded when effective control over the transferred financial assets is maintained while a sale is recorded when effective control over the transferred financial assets has not been maintained. The new guidance removes from the assessment of effective control: (1) the criterion requiring the transferor to have the ability to repurchase or redeem financial assets before their maturity on substantially the agreed terms, even in the event of the transferee's default, and (2) the collateral maintenance implementation guidance related to that criterion. This guidance is effective for the Bank's interim and annual periods beginning on January 1, 2012. This guidance will be applied prospectively to transactions or modifications of existing transactions that occur on or after the effective date. Early adoption is not permitted. The adoption of this guidance is not expected to have a material effect on the Bank's financial condition, results of operations, or cash flows.

A Creditor’s Determination of Whether a Restructuring is a Troubled Debt Restructuring. On April 5, 2011, the FASB issued guidance to clarify which debt modifications constitute troubled debt restructurings. It is intended to help creditors determine whether a modification of the terms of a receivable meets the criteria to be considered a troubled debt restructuring, both for purposes of recording an impairment loss and for presenting previously deferred disclosures related to troubled debt restructurings. This guidance is effective for interim and annual periods beginning on or after June 15, 2011 (July 1, 2011, for the Bank), and applies retrospectively to troubled debt restructurings occurring on or after the beginning of the annual period of adoption. The adoption of this amended guidance did not have a material effect on the Bank's financial condition, results of operations, or cash flows.

Disclosures about the Credit Quality of Financing Receivables and the Allowance for Credit Losses. On July 21, 2010, the FASB issued amended guidance to enhance disclosures about an entity's allowance for credit losses and the credit quality of its financing receivables. The required disclosures as of the end of a reporting period became effective for interim and annual reporting periods ending on December 31, 2010. The required disclosures about activity that occurs during a reporting period became effective for interim and annual reporting periods beginning on January 1, 2011. The adoption of this amended guidance resulted in increased annual and interim financial statement disclosures, but did not affect the Bank's financial condition, results of operations, or cash flows.

On January 19, 2011, the FASB issued guidance to temporarily defer the effective date of disclosures about troubled debt restructurings required by the amended guidance on disclosures about the credit quality of financing receivables and the allowance for credit losses. The effective date for these new disclosures was coordinated with the effective date of the guidance for determining what constitutes a troubled debt restructuring.

Mortgage Loans Held for Portfolio

The Bank invests in fixed-rate single-family mortgages through the Mortgage Partnership Finance® (MPF®) program. These investments in mortgage loans are guaranteed or insured by federal agencies or are credit-enhanced by participating financial institutions. All such mortgage loans are held for portfolio. These investments in mortgage loans are originated and credit-enhanced by the originating institution. The majority of these loans are serviced by the originating institution. A portion of these loans are sold servicing-released by the participating financial institution and serviced by a third party servicer.

Allowance for Credit Losses [Abstract]

Allowance for Credit Losses [Text Block]

Allowance for Credit Losses

Allowance for Credit Losses Policy

An allowance for credit losses is a valuation allowance separately established for each identified portfolio segment, if necessary, to provide for probable losses inherent in the Bank's portfolio as of the statement of condition date. To the extent necessary, an allowance for credit losses for off-balance-sheet credit exposure is recorded as a liability.

Portfolio Segments. The Bank has established an allowance methodology for each of the Bank's portfolio segments. A portfolio segment is defined as the level at which an entity develops and documents a systematic method for determining its allowance for credit losses. The Bank has developed and documented a systematic methodology for determining an allowance for credit losses for 1) advances, letters of credit, and other extensions of credit to members, collectively referred to as credit products; 2) government-guaranteed or -insured mortgage loans held for portfolio; 3) conventional mortgage loans held for portfolio; 4) securities purchased under agreements to resell; and 5) federal funds sold.

Classes of Financing Receivables. Classes of financing receivables generally are a disaggregation of a portfolio segment to the extent that it is needed to understand the exposure to credit risk arising from these financing receivables. The Bank determined that no further disaggregation of portfolio segments identified above is needed as the credit risk arising from these financing receivables is assessed and measured by the Bank at the portfolio segment level.

Impairment Methodology. A loan is considered impaired when, based on current information and events, it is probable that the Bank will be unable to collect all amounts due according to the contractual terms of the loan agreement.

Loans that are on nonaccrual status and that are considered collateral-dependent are measured for impairment based on the fair value of the underlying property less estimated selling costs. Loans are considered collateral-dependent if repayment is expected to be provided solely by the sale of the underlying property, that is, there is no other available and reliable source of repayment. Collateral-dependent loans are impaired if the fair value of the underlying collateral is insufficient to recover the unpaid principal balance on the loan. Interest income on impaired loans is recognized in the same manner as nonaccrual loans as discussed below.

Nonaccrual Loans. The Bank places conventional mortgage loans on nonaccrual status when the collection of the contractual principal or interest is 90 days or more past due. When a conventional mortgage loan is placed on nonaccrual status, accrued but uncollected interest is reversed against interest income in the current period. The Bank generally records cash payments received on nonaccrual loans first as interest income and then as a reduction of principal as specified in the contractual agreement, unless the collection of the remaining principal amount due is considered doubtful. If the collection of the remaining principal amount due is considered doubtful, cash payments received would be applied first solely to principal until the remaining principal amount due is expected to be collected and then as a recovery of any charge-off, if applicable, followed by recording interest income. A loan on nonaccrual status may be restored to accrual status when the collection of the contractual principal and interest is less than 90 days past due. Government-insured and -guaranteed loans are not placed on nonaccrual status when the collection of the contractual principal or interest is 90 days or more past due because of (1) the U.S. government guarantee of the loan and (2) the contractual obligation of the loan servicer.

Charge-Off Policy. The Bank evaluates whether to record a charge-off on a conventional mortgage loan upon the occurrence of a confirming event. Confirming events include, but are not limited to, the occurrence of foreclosure or notification of a claim against any of the credit enhancements. A charge-off is recorded if the Bank determines that the recorded investment in the loan is not likely to be recovered.

Credit Products

The Bank manages its credit exposure to credit products through an integrated approach that generally provides for a credit limit to be established for each borrower, includes an ongoing review of each borrower's financial condition, and is coupled with conservative collateral/lending policies to limit risk of loss while balancing borrowers' needs for a reliable source of funding. In addition, the Bank lends in accordance with federal statutes and Finance Agency regulations. Specifically, the Bank complies with the FHLBank Act, which requires the Bank to obtain sufficient collateral to fully secure credit products. The estimated value of the collateral pledged to secure each member's credit products is calculated by applying collateral discounts, or haircuts, to the value of the collateral. The Bank accepts certain investment securities, residential mortgage loans, deposits, and other real estate related assets as collateral. The Bank requires all borrowers that pledge securities collateral to place physical possession of such securities collateral with the Bank's safekeeping agent or the borrower's securities corporation, subject to a control agreement giving the Bank appropriate control over such collateral. In addition, CFIs are eligible to use expanded statutory collateral provisions for small-business and agriculture loans. The Bank's capital stock owned by members is also pledged as collateral. Collateral arrangements may vary depending upon borrower credit quality, financial condition, performance, borrowing capacity, and overall credit exposure to the borrower. The Bank can call for additional or substitute collateral to protect its security interest. Management believes these policies effectively manage the Bank's respective credit risk from credit products.

Based upon the financial condition of the borrower, the Bank may allow the borrower to retain possession of loan collateral pledged to the Bank while agreeing to hold such collateral for the benefit of the Bank or require the borrower to specifically assign or place physical possession of such loan collateral with the Bank or a third-party custodian approved by the Bank.

The Bank is provided an additional safeguard for its security interests by Section 10(e) of the FHLBank Act, which affords any security interest granted by a member or borrower to the Bank priority over the claims and rights of any other party. The exceptions to this prioritization are limited to claims that would be entitled to priority under otherwise applicable law and are held by bona fide purchasers for value or by secured parties with higher priority perfected security interests. However, the priority granted to the security interests of the Bank under Section 10(e) of the FHLBank Act may not apply when lending to insurance company members. This is due to the anti-preemption provision contained in the McCarran-Ferguson Act in which the U.S. Congress (Congress) declared that federal law would not preempt state insurance law unless the federal law expressly regulates the business of insurance. Thus, if state law conflicts with Section 10(e) of the FHLBank Act, the protection afforded by this provision may not be available to the Bank. However, the Bank perfects its security interests in the collateral pledged by its members, including insurance company members, by filing UCC-1 financing statements, or by taking possession or control of such collateral, or by taking other appropriate steps.

Using a risk-based approach and taking into consideration each borrower's financial strength, the Bank considers the types and level of collateral to be the primary indicator of credit quality on its credit products. At September 30, 2011, the Bank had rights to collateral, on a borrower-by-borrower basis, with an estimated value in excess of its outstanding extensions of credit. The estimated value of the collateral required to secure each member's obligations is calculated by applying collateral discounts or haircuts.

The Bank continues to evaluate and make changes to its collateral guidelines, as the Bank believes necessary, based on current market conditions. At September 30, 2011, and December 31, 2010, the Bank did not have any credit products that were past due, on nonaccrual status, or considered impaired. In addition, there have been no troubled debt restructurings related to credit products during the nine months ended September 30, 2011 and 2010.

Based upon the collateral held as security, its credit extension and collateral policies, management's credit analysis, and the repayment history on credit products, the Bank has not recorded any allowance for credit losses on credit products at September 30, 2011, and December 31, 2010. At September 30, 2011, and December 31, 2010, no liability to reflect an allowance for credit losses for off-balance-sheet credit exposures was recorded. See Note 18 — Commitments and Contingencies for additional information on the Bank's off-balance-sheet credit exposure.

MortgageLoans- Government-insured or -guaranteed

The Bank invests in government-insured or -guaranteed fixed-rate mortgage loans secured by one- to four-family residential properties. Government-guaranteed mortgage loans are mortgage loans insured or guaranteed by the Federal Housing Administration, the Department of Veterans Affairs, the Rural Housing Service of the Department of Agriculture, and/or by the U.S. Department of Housing and Urban Development. The servicer provides and maintains insurance or a guaranty from the applicable government agency. The servicer is responsible for compliance with all government agency requirements and for obtaining the benefit of the applicable insurance or guaranty with respect to defaulted government-guaranteed mortgage loans. Any losses incurred on such loans that are not recovered from the issuer or guarantor are absorbed by the servicers. Therefore, the Bank only has credit risk for these loans if the servicers fail to pay for losses not covered by the applicable government agency. Based on the Bank's assessment of its servicers for these loans, there is no allowance for credit losses for the government-insured and -guaranteed mortgage loans portfolio as of September 30, 2011, and December 31, 2010. In addition, due to the government guarantee or insurance, these mortgage loans are not placed on nonaccrual status.

Mortgage Loans - Conventional

The allowance for conventional mortgage loans is determined by analysis that includes consideration of various data including past performance, current performance, loan portfolio characteristics, collateral-related characteristics, the state of the housing industry, and prevailing economic conditions. The measurement of the allowance for loan losses may consist of (1) reviewing all residential mortgage loans as pool loans based on individual master commitments; (2) reviewing specifically identified collateral-dependent loans for impairment; (3) reviewing homogeneous pools of residential mortgage loans; and/or (4) estimating credit losses in the remaining portfolio.

The Bank's allowance for credit losses factors in the credit enhancements associated with conventional mortgage loans (which may include primary or supplemental mortgage insurance) under the MPF program. Any incurred losses that would be recovered from the credit enhancements are not reserved as part of the Bank's allowance for loan losses. In such cases, a receivable is generally established to reflect the expected recovery from credit-enhancement arrangements. The Bank records credit-enhancement fees paid to participating financial institutions as a reduction to mortgage-loan-interest income. The Bank incurred credit-enhancement fees of $762,000 and $838,000 for the three months ended September 30, 2011 and 2010, respectively. For the nine months ended September 30, 2011 and 2010, the Bank incurred credit-enhancement fees of $2.3 million and $2.6 million respectively.

For conventional mortgage loans, credit losses that are not paid by primary mortgage insurance are allocated to the Bank up to the first-loss account. The aggregated amount of the first-loss account is documented and tracked but is neither recorded nor reported as an allowance for loan losses in the Bank's financial statements. As credit and special hazard losses are realized that are not covered by the liquidation value of the real property or primary mortgage insurance, they are first charged to the Bank, with a corresponding reduction of the first-loss account for that master commitment up to the amount accumulated in the first-loss account at that time. Over time, the first-loss account may cover the expected credit losses on a master commitment, although losses that are greater than expected or that occur early in the life of the master commitment could exceed the amount accumulated in the first-loss account. In that case, the excess losses would be charged next to the member's credit-enhancement amount, then to the Bank after the member's credit-enhancement amount has been exhausted. The amount of the first-loss account remaining to absorb losses for loans owned by the Bank is partly dependent on the percentage of loans owned by the Bank that are within master commitments which include loans that are owned, in whole or in part, by other MPF Banks. Assuming losses occur on a proportional basis between loans owned by the Bank and loans owned by other MPF Banks, at September 30, 2011, and December 31, 2010, the amount of first-loss account remaining for losses attributable to the Bank was $24.4 million and $27.8 million, respectively. For certain MPF products, the Bank's losses incurred under the first-loss account can be mitigated by withholding future performance credit-enhancement fees that would otherwise be payable to the participating financial institutions.

Collectively Evaluated Mortgage Loans. The credit risk analysis of conventional mortgage loans evaluated collectively for impairment considers loan-pool-specific attribute data at the master commitment pool level, applies estimated loss severities, and incorporates the credit enhancements of the MPF program. Migration analysis is a methodology for estimating, through the Bank's experience over a historical period, the rate of default experienced on pools of similar loans. The Bank applies migration analysis to loans based on its experience with loans that are currently not past due, loans that are 30 to 59 days past due, 60 to 89 days past due, and 90 or more days past due, as well as to loans 60 or more days past due following receipt of notice of filing from the bankruptcy court. The Bank then estimates the dollar amount of loans in these categories that may migrate to a realized loss position and apply a loss severity factor to estimate losses incurred at the statement of condition date.

Individually Evaluated Mortgage Loans. Certain conventional mortgage loans (typically impaired mortgage loans that are considered collateral dependent), may be specifically identified for purposes of calculating the allowance for credit losses.

A mortgage loan is considered collateral dependent if repayment is only expected to be provided by the sale of the underlying property, that is, if it is considered likely that the borrower will default and there is no credit enhancement from a participating financial institution to offset losses under the master commitment. The estimated credit losses on impaired collateral-dependent loans may be separately determined because sufficient information exists to make a reasonable estimate of the inherent loss for such loans on an individual loan basis. The Bank applies an estimated loss severity rate, which is used to estimate the fair value of the collateral. The resulting loss recorded is equal to the carrying value of the loan less the estimated fair value of the collateral less estimated selling costs.

Estimating Credit Loss in the Remaining Portfolio. The Bank also assesses a factor for the margin for imprecision to the estimation of credit losses for the homogeneous population. The margin for imprecision is a factor in the allowance for credit losses that recognizes the imprecise nature of the measurement process and is included as part of the mortgage loan allowance for credit loss. This amount represents a subjective management judgment based on facts and circumstances that exist as of the reporting date that is unallocated to any specific measurable economic or credit event and is intended to cover other inherent losses that may not be captured in the methodology described within. The actual loss that may occur on homogeneous populations of mortgage loans may be more or less than the estimated loss.

Roll-Forward of Allowance for Credit Losses on Mortgage Loans. As of September 30, 2011, and December 31, 2010, the Bank determined that an allowance for credit losses should be established for credit losses on its conventional mortgage loans. The following table presents a roll-forward of the allowance for credit losses on mortgage loans for the three and nine months endedSeptember 30, 2011 and 2010, as well as the recorded investment in mortgage loans by impairment methodology at September 30, 2011 (dollars in thousands). The recorded investment in a loan is the par amount of the loan, adjusted for accrued interest, unamortized premiums or discounts, deferred derivative gains and losses, and direct write-downs. The recorded investment is not net of any valuation allowance.

Troubled Debt Restructurings.

Troubled debt restructuring is considered to have occurred when a concession is granted to the debtor that would not otherwise be considered for economic or legal reasons related to the debtor's financial difficulties.

The Bank's program for MPF loan troubled debt restructurings primarily involve modifying the borrower's monthly payment for a period of up to 36 months to no more than a housing expense ratio of 38 percent of their monthly income. The outstanding principal balance is re-amortized to reflect a principal and interest payment for a term not to exceed 40 years and a housing expense ratio not to exceed 38 percent. This would result in a balloon payment at the original maturity date of the loan as the maturity date and number of remaining monthly payments is unchanged. If the 38 percent ratio is still not met, the interest rate is reduced for up to 36 months in 0.125 percent increments below the original note rate, to a floor rate of 3.00 percent, resulting in reduced principal and interest payments, until the target 38 percent housing expense ratio is met.

As discussed in Note 2 — Recently Issued Accounting Standards and Interpretations, the Bank adopted amended guidance intended to clarify which debt modifications constitute troubled debt restructurings. The Bank has had no new modifications that occurred on or after January 1, 2011, and did not identify any additional troubled debt restructurings as a result of adopting this amended guidance.

As of September 30, 2011, and December 31, 2010, the Bank had one MPF loan with a recorded investment of $245,000 and $238,000, respectively that is considered a troubled debt restructuring. As of September 30, 2011, the Bank's one troubled debt restructuring was performing and had not defaulted.

Real Estate Owned Assets.

The Bank's REO includes assets that have been received in satisfaction of debt or as a result of actual foreclosures. REO is initially recorded as other assets in the statement of condition and is carried at the lower of cost or fair value less estimated selling costs. Fair value is defined as the amount that a willing seller could expect from a willing buyer in an arm's-length transaction. If the fair value of the REO is less than the recorded investment in the MPF loan at the date of transfer, the Bank recognizes a charge-off to the allowance for credit losses. Subsequent realized gains and realized or unrealized losses are included in other income (loss) in the statement of operations.

At September 30, 2011, and December 31, 2010, the Bank had $6.3 million and $6.5 million, respectively, in assets classified as REO. During the nine months ended September 30, 2011 and 2010, the Bank sold REO assets with a recorded carrying value of $7.5 million and $6.8 million, respectively. Upon sale of these properties, and inclusive of any proceeds received from primary mortgage-insurance coverage, the Bank recognized net gains totaling $400,000 and $226,000 on the sale of REO assets during the nine months ended September 30, 2011 and 2010, respectively. Gains and losses on the sale of REO assets are recorded in other income.

Federal Funds Sold and Securities Purchased Under Agreements to Resell

These investments are all short-term (all less than three months) and the recorded balance approximates fair value. The Bank invests in federal funds sold with highly rated counterparties and are only evaluated for purposes of an allowance for credit losses if the investment is not paid when due. All investments in federal funds sold as of September 30, 2011, and December 31, 2010, were repaid according to the contractual terms. Securities purchased under agreements to resell are considered collateralized financing arrangements and effectively represent short-term loans to highly rated counterparties. The terms of these loans are structured such that if the market value of the underlying securities decreases below the market value required as collateral, the counterparty must provide additional securities as collateral in an amount equal to the decrease or remit cash in such amount, or the dollar value of the resale agreement will be decreased accordingly. If an agreement to resell is deemed to be impaired, the difference between the fair value of the collateral and the amortized cost of the agreement is charged to earnings. Based upon the collateral held as security, the Bank determined that no allowance for credit losses was needed for the securities purchased under agreements to resell at September 30, 2011, and December 31, 2010.

Purchases, Sales, and Reclassifications

During the nine months ended September 30, 2011, there were no significant purchases or sales of financing receivables. Furthermore, there were no reclassifications of financing receivables to held for sale during the period.

The Bank offers callable advances that provide members with the right, based upon predetermined option exercise dates, to call the advance prior to maturity without incurring prepayment or termination fees (callable advances). Other advances may only be prepaid by paying a fee to the Bank (prepayment fee) that makes the Bank financially indifferent to the prepayment of the advance. At September 30, 2011, and December 31, 2010, the Bank had callable advances outstanding totaling $2.5 million and $11.5 million, respectively.

The following table summarizes advances outstanding by year of contractual maturity or next call date for callable advances (dollars in thousands):

The Bank also offers putable advances that provide the Bank with the right to put the fixed-rate advance to the member (and thereby extinguish the advance) on predetermined exercise dates, and offer, subject to certain conditions, replacement funding at then-current Bank rates. Generally, such put options are exercised when interest rates increase. At September 30, 2011, and December 31, 2010, the Bank had putable advances outstanding totaling $5.2 billion and $6.8 billion, respectively.

The following table summarizes advances outstanding by year of contractual maturity or next put date for putable advances (dollars in thousands):

Credit Risk Exposure and Security Terms.

The Bank's potential credit risk from advances is principally concentrated in commercial banks, savings institutions, and credit unions. At September 30, 2011, and December 31, 2010, the Bank had $6.5 billion and $8.8 billion, respectively, of advances outstanding that were greater than or equal to $1.0 billion per borrower. These advances were made to two borrowers at September 30, 2011, and three borrowers at December 31, 2010, representing 26.8 percent and 32.2 percent, respectively, of total advances outstanding.

The Bank lends to its members and state and local housing authorities (housing associates) chartered within the six New England states in accordance with federal statutes, including the Federal Home Loan Bank Act of 1932, as amended (the FHLBank Act). The FHLBank Act generally requires the Bank to hold, or have access to, collateral to secure the Bank's advances. While the Bank has never experienced a credit loss on an advance to a borrower, weakening economic conditions, severe credit market conditions, along with the expanded statutory collateral rules for community financial institutions (CFIs) and the incremental risk inherent in lending to housing associates, insurance companies, and community development financial institutions, provide the potential for additional credit risk for the Bank. The Bank has policies and procedures in place to manage credit risk including, without limitation, requirements for physical possession or control of pledged collateral, restrictions on borrowing, specific review of each advance request, verifications of collateral, and continuous monitoring of borrowings and the borrower's financial condition. Based on the collateral pledged as security for advances, management's credit analysis of the borrower's financial condition, and credit extension and collateral policies, the Bank does not expect any losses on advances and expects to collect all amounts due according to the contractual terms of the advances. Therefore, the Bank has not provided any allowance for losses on advances. For information related to the Bank's credit risk on advances and allowance for credit losses, see Note 9 — Allowance for Credit Losses.

_______________________

(1)Carrying value of held-to-maturity securities represents the sum of amortized cost and the amount of noncredit-related other-than-temporary impairment recognized in accumulated other comprehensive loss.

(2) MBS are not presented by contractual maturity because their expected maturities will likely differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment fees.

As of September 30, 2011, the amortized cost of the Bank's held-to-maturity securities includes net discounts of $542.5 million. Of that amount, net premiums of $4.0 million relate to non-MBS and net discounts of $546.5 million relate to MBS. As of December 31, 2010, the amortized cost of the Bank's held-to-maturity securities includes net discounts of $523.4 million. Of that amount, net premiums of $5.3 million relate to non-MBS and net discounts of $528.7 million relate to MBS.

Employee Retirement Plans

Qualified Defined Benefit Multi-Employer Plan. The Bank participates in the Pentegra Defined Benefit Plan for Financial Institutions (Pentegra Defined Benefit Plan), a funded, tax-qualified, noncontributory defined-benefit pension plan. The Pentegra Defined Benefit Plan is a multi-employer plan in which assets contributed by one participating employer may be used to provide benefits to employees of other participating employers since assets contributed by an employer are not segregated in a separate account or restricted to provide benefits only to employees of that employer. As a result, disclosure of the accumulated benefit obligations, plan assets, and the components of annual pension expense attributable to the Bank is not made. The plan covers substantially all officers and employees of the Bank. Funding and administrative costs of the Pentegra Defined Benefit Plan charged to compensation and benefit expense were $1.3 million and $1.1 million for the three months ended September 30, 2011, and 2010, respectively. Funding and administrative costs of the Pentegra Defined Benefit Plan charged to compensation and benefit expense were $3.1 million and $3.4 million for the nine months ended September 30, 2011, and 2010, respectively.

Qualified Defined Contribution Plan. The Bank also participates in the Pentegra Defined Contribution Plan for Financial Institutions, a tax-qualified defined contribution plan. The plan covers substantially all officers and employees of the Bank. The Bank contributes a percentage of the participants' compensation by making a matching contribution equal to a percentage of voluntary employee contributions, subject to certain limitations. The Bank's matching contributions charged to compensation and benefit expense were $212,000 and $205,000 in the three months ended September 30, 2011 and 2010, respectively. The Bank's matching contributions charged to compensation and benefit expense were $646,000 and $621,000 for the nine months ended September 30, 2011 and 2010, respectively.

Nonqualified Defined Contribution Plan. The Bank also maintains the Thrift Benefit Equalization Plan, a nonqualified, unfunded deferred compensation plan covering certain senior officers and directors of the Bank, as defined in the plan. The plan's liability consists of the accumulated compensation deferrals and the accumulated earnings on these deferrals. The Bank recognized expenses of $16,000 and $17,000 in the three months ended September 30, 2011 and 2010, respectively, related to this plan. The Bank recognized expenses of $68,000 and $34,000 in the nine months ended September 30, 2011 and 2010, respectively, related to this plan. The Bank's obligation from this plan, was $2.9 million at both September 30, 2011, and December 31, 2010. The Bank maintains a rabbi trust intended to meet future benefit obligations.

Nonqualified Supplemental Defined Benefit Retirement Plan. The Bank also maintains a nonqualified, unfunded defined-benefit plan covering certain senior officers, as defined in the plan. The Bank maintains a rabbi trust intended to meet future benefit obligations.

Postretirement Benefits. The Bank sponsors a fully insured postretirement benefit program that includes life insurance benefits for eligible retirees. The Bank provides life insurance to all employees who retire on or after age 55 after completing six years of service. No contributions are required from the retirees. There are no funded plan assets that have been designated to provide postretirement benefits.

In connection with the nonqualified supplemental defined benefit retirement plan and postretirement benefits, the Bank recorded the following amounts as of September 30, 2011, and December 31, 2010 (dollars in thousands):

Segment Reporting Disclosure [Text Block]

Segment Information

In the first quarter of 2011, the Bank began reporting on an enterprise-wide basis rather than providing separate segment information for the MPF program. The enterprise-wide method of evaluating the Bank's financial information reflects the manner in which the chief operating decision-maker manages the business. Accordingly, the Bank will no longer present separate Mortgage Loan Finance segment information.

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies Disclosure [Text Block]

Commitments and Contingencies

Joint and Several Liability. COs are backed by the financial resources of the FHLBanks. The joint and several liability regulation of the Finance Agency authorizes the Finance Agency to require any FHLBank to repay all or a portion of the principal and interest on COs for which another FHLBank is the primary obligor. No FHLBank has ever been asked or required to repay the principal or interest on any CO on behalf of another FHLBank. The Bank evaluates the financial condition of the other FHLBanks primarily based on known regulatory actions, publicly available financial information, and individual long-term credit-rating action as of each period-end presented. Based on this evaluation, as of September 30, 2011, and through the filing of this report, the Bank does not believe that it is reasonably likely to be required to repay the principal or interest on any CO on behalf of another FHLBank.

The Bank has considered applicable FASB guidance and determined it is not necessary to recognize a liability for the fair value of the Bank's joint and several liability for all of the COs. The joint and several obligation is mandated by Finance Agency regulations and is not the result of an arms-length transaction among the FHLBanks. The FHLBanks have no control over the amount of the guaranty or the determination of how each FHLBank would perform under the joint and several obligation. Because the FHLBanks are subject to the authority of the Finance Agency as it relates to decisions involving the allocation of the joint and several liability for the FHLBanks' COs, the FHLBanks' joint and several obligation is excluded from the initial recognition and measurement provisions. Accordingly, the Bank has not recognized a liability for its joint and several obligation related to other FHLBanks' COs at September 30, 2011, and December 31, 2010. The par amounts of other FHLBanks' outstanding COs for which the Bank is jointly and severally liable totaled approximately $653.9 billion and $743.0 billion at September 30, 2011, and December 31, 2010, respectively. See Note 12 — Consolidated Obligations for additional information.

Off-Balance-Sheet Commitments

The following table shows the Bank's off-balance-sheet commitments as of September 30, 2011, and December 31, 2010 (dollars in thousands):

	September 30, 2011						December 31, 2010
	Expire within one year		Expire after one year		Total		Expire within one year		Expire after one year		Total
Standby letters of credit outstanding (1)	$	849,637	$	417,762	$	1,267,399	$	821,443	$	693,309	$	1,514,752

Unsettled CO discount notes, at par	—		—		—		29,400		—		29,400

__________________________

(1) Excludes commitments to issue standby letters of credit that expire within one year totaling $31.4 million as of September 30, 2011.

(2) Commitments for unused line-of-credit advances are generally for periods of up to 12 months. Since many of these commitments are not expected to be drawn upon, the total commitment amount does not necessarily indicate future liquidity requirements.

(3) The Bank had $215.0 million in unsettled CO bonds which were hedged with associated interest-rate swaps at September 30, 2011. No unsettled CO bonds were hedged with associated interest-rate exchange agreements at December 31, 2010.

Commitments to Extend Credit. Standby letters of credit are executed with members or housing associates for a fee.A standby letter of credit is a financing arrangement between the Bank and a member or housing associate pursuant to which the Bank (for a fee) agrees to fund the associated member's or housing associate's obligation to a third-party beneficiary should that member or housing associate fail to fund such obligation. If the Bank is required to make payment for a beneficiary's draw, the payment amount is converted into a collateralized advance to the member or housing associate. The original terms of these standby letters of credit, including related commitments, range from two months to 20 years, including a final expiration in 2024.

Unearned fees for the value of the guarantees related to standby letters of credit are recorded in other liabilities and totaled $685,000 and $891,000 at September 30, 2011, and December 31, 2010, respectively. Based on management's credit analyses and collateral requirements, the Bank has not deemed it necessary to record any additional liability on these commitments. Commitments are fully collateralized at the time of issuance.

The Bank monitors the creditworthiness of its members and housing associates that have standby letter of credit agreements outstanding based on an evaluation of their financial condition. The Bank reviews available financial data, such as regulatory call reports filed by depository institution members, regulatory financial statements filed with the appropriate state insurance department by insurance company members, audited financial statements of housing associates, SEC filings, and rating-agency reports to ensure that potentially troubled members are identified as soon as possible. In addition, the Bank has access to most members' regulatory examination reports. The Bank analyzes this information on a regular basis.

Standby Bond-Purchase Agreements. The Bank has entered into standby bond-purchase agreements with state housing authorities whereby the Bank, for a fee, agrees to purchase and hold the housing authority’s bonds until the designated remarketing agent can find a suitable investor or the housing authority repurchases the bonds according to a schedule established by the standby agreement. Each standby agreement dictates the specific terms that would require the Bank to purchase the bonds. The standby bond-purchase commitments entered into by the Bank expire between one and three years following the start of the commitment, currently no later than 2013. At September 30, 2011, the Bank had standby bond purchase agreements with one state housing authority. At December 31, 2010, the Bank had standby bond purchase agreements with two state housing authorities. During the nine months ended September 30, 2011, and year ended December 31, 2010, the Bank was not required to purchase any bonds under these agreements.

Commitments to Invest in Mortgage Loans. Commitments to invest in mortgage loans are generally for periods not to exceed 45 business days. Such commitments are recorded as derivatives at their fair values on the statement of condition.

Pledged Collateral. The Bank executes new derivatives with counterparties with long-term ratings of single-A (or equivalent) or better by either S&P or Moody’s, and enters into bilateral-collateral agreements. Derivatives with counterparties rated lower than single-A (or equivalent) are permitted only if they reduce exposure to that counterparty. As of September 30, 2011, and December 31, 2010, the Bank had pledged as collateral securities with a carrying value, including accrued interest, of $759.5 million and $397.2 million, respectively, to counterparties that have credit-risk exposure to the Bank related to derivatives. These amounts pledged as collateral were subject to contractual agreements whereby some counterparties had the right to sell or repledge the collateral.

Legal Proceedings.

The Bank is subject to various other pending legal proceedings arising in the normal course of business. Management does not anticipate that the ultimate liability, if any, arising out of these matters will have a material effect on the Bank’s financial condition, results of operations, or cash flows.

Basis of Presentation

The accompanying unaudited financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) for interim financial information. Accordingly, they do not include all of the information and footnotes required by GAAP for complete annual financial statements. In the opinion of management, all adjustments considered necessary have been included. All such adjustments consist of normal recurring accruals. The presentation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. The results of operations for interim periods are not necessarily indicative of the results to be expected for the year ending December 31, 2011. The unaudited financial statements should be read in conjunction with the Federal Home Loan Bank of Boston's (the Bank's) audited financial statements and related notes in the Bank's Annual Report on Form 10-K for the year ended December 31, 2010, filed with the Securities and Exchange Commission (the SEC) on March 18, 2011 (the 2010 Annual Report).

Derivatives and Hedging Activities

Derivatives and Hedging Activities [Abstract]

Derivative Instruments and Hedging Activities Disclosure [Text Block]

Derivatives and Hedging Activities

All derivatives are recognized on the statement of condition at fair value. The Bank offsets fair-value amounts recognized for derivative instruments and fair-value amounts recognized for the right to reclaim cash collateral (a receivable) or the obligation to return cash collateral (a payable) arising from derivative instruments recognized at fair value executed with the same counterparty under a master-netting arrangement. Derivative assets and derivative liabilities reported on the statement of condition also include net accrued interest.

Each derivative is designated as one of the following:

(1)a qualifying hedge of the change in fair value of a recognized asset or liability or an unrecognized firm commitment (a fair-value hedge);

(2)a qualifying hedge of a forecasted transaction or the variability of cash flows that are to be received or paid in connection with a recognized asset or liability (a cash-flow hedge);

(3)a nonqualifying hedge of an asset or liability (economic hedge) for asset-liability-management purposes; or

(4)a nonqualifying hedge of another derivative (an intermediation instrument) that is offered as a product to members or used to offset other derivatives with nonmember counterparties.

Accounting for Qualifying Hedges. If hedging relationships meet certain criteria, including, but not limited to, formal documentation of the hedging relationship and an expectation to be highly effective, they qualify for hedge accounting and the offsetting changes in fair value of the hedged items may be recorded either in earnings (fair-value hedges) or accumulated other comprehensive loss (cash-flow hedges). Two approaches to hedge accounting include:

(1) Long-haul hedge accounting - The application of long-haul hedge accounting generally requires the Bank to formally assess (both at the hedge's inception and at least quarterly) whether the derivatives that are used in hedging transactions have been effective in offsetting changes in the fair value or cash flows of hedged items or forecasted transactions and whether those derivatives may be expected to remain effective in future periods. 

(2) Short-cut hedge accounting - Transactions that meet certain criteria qualify for the short-cut method of hedge accounting in which an assumption can be made that the change in fair value of a hedged item, due to changes in the benchmark rate, exactly offsets the change in fair value of the related derivative. Under the shortcut method, the entire change in fair value of the interest-rate swap is considered to be effective at achieving offsetting changes in fair values or cash flows of the hedged asset or liability.

Derivatives that are used in fair-value hedges are typically executed at the same time as the hedged items, and the Bank designates the hedged item in a qualifying hedge relationship as of the trade date. In many hedging relationships that use the shortcut method, the Bank may designate the hedging relationship upon its commitment to disburse an advance or trade a consolidated obligation (CO) that settles within the shortest period of time possible for the type of instrument based on market-settlement conventions. In such circumstances, although the advance or CO will not be recognized in the financial statements until settlement date, the hedge meets the criteria for applying the short-cut method, provided all other short-cut criteria are also met. The Bank then records the changes in fair value of the derivative and the hedged item beginning on the trade date.

Changes in the fair value of a derivative that is designated and qualifies as a fair-value hedge, along with changes in the fair value of the hedged asset or liability that are attributable to the hedged risk (including changes that reflect losses or gains on firm commitments), are recorded in other income (loss) as net gains (losses) on derivatives and hedging activities.

Changes in the fair value of a derivative that is designated and qualifies as a cash-flow hedge, to the extent that the hedge is effective, are recorded in accumulated other comprehensive loss, a component of capital, until earnings are affected by the variability of the cash flows of the hedged transaction.

For both fair-value and cash-flow hedges, any hedge ineffectiveness (which represents the amount by which the changes in the fair value of the derivative differ from the change in the fair value of the hedged item or the variability in the cash flows of the forecasted transaction) is recorded in other income (loss) as net gains (losses) on derivatives and hedging activities.

Accounting for Nonqualifying Hedges. An economic hedge is defined as a derivative hedging specific or nonspecific assets, liabilities, or firm commitments that does not qualify or was not designated for hedge accounting, but is an acceptable hedging strategy under the Bank's risk-management policy. These economic hedging strategies also comply with Finance Agency regulatory requirements prohibiting speculative derivative transactions. An economic hedge by definition introduces the potential for earnings variability caused by the changes in fair value of the derivatives that are recorded in income but not offset by corresponding changes in the fair value of the economically hedged assets, liabilities, or firm commitments. As a result, the Bank recognizes only the net interest and the change in fair value of these derivatives in other income (loss) as net gains (losses) on derivatives and hedging activities with no offsetting fair-value adjustments for the economically hedged assets, liabilities, or firm commitments. Cash flows associated with such stand-alone derivatives (derivatives not qualifying as a hedge) are reflected as cash flows from operating activities in the statement of cash flows unless the derivative meets the criteria to be a financing derivative.

Accrued Interest Receivable and Payable. The differential between accrual of interest receivable and payable on derivatives designated as a fair-value hedge or as a cash-flow hedge is recognized through adjustments to the interest income or interest expense of the designated hedged investment securities, advances, COs, deposits, or other financial instruments. The differential between accrual of interest receivable and payable on intermediated derivatives for members and other economic hedges is recognized in other income (loss), along with changes in fair value of these derivatives, as net gains (losses) on derivatives and hedging activities.

Discontinuance of Hedge Accounting. The Bank may discontinue hedge accounting prospectively when: (1) it is determined that the derivative is no longer effective in offsetting changes in the fair value or cash flows of a hedged item (including hedged items such as firm commitments or forecasted transactions); (2) the derivative and/or the hedged item expires or is sold, terminated, or exercised; (3) it is no longer probable that the forecasted transaction will occur in the originally expected period; (4) a hedged firm commitment no longer meets the definition of a firm commitment; or (5) management determines that designating the derivative as a hedging instrument is no longer appropriate.

When hedge accounting is discontinued because the Bank determines that the derivative no longer qualifies as an effective fair-value hedge of an existing hedged item, the Bank either terminates the derivative or continues to carry the derivative on the statement of condition at its fair value, ceases to adjust the hedged asset or liability for changes in fair value, and begins to amortize the cumulative basis adjustment on the hedged item into earnings over the remaining life of the hedged item using the level-yield method.

When hedge accounting is discontinued because the Bank determines that the derivative no longer qualifies as an effective cash-flow hedge of an existing hedged item, the Bank continues to carry the derivative on the statement of condition at its fair value and amortizes the cumulative other comprehensive loss adjustment to earnings when earnings are affected by the existing hedged item.

Under limited circumstances, when the Bank discontinues cash-flow hedge accounting because it is no longer probable that the forecasted transaction will occur in the originally expected period plus the following two months, but it is probable that the transaction will still occur in the future, the gain or loss on the derivative remains in accumulated other comprehensive loss and is recognized in earnings when the forecasted transaction affects earnings. However, if it is probable that a forecasted transaction will not occur by the end of the originally specified time period or within two months thereafter, the gain or loss that was accumulated in other comprehensive loss is recognized immediately in earnings.

When hedge accounting is discontinued because the hedged item no longer meets the definition of a firm commitment, the Bank continues to carry the derivative on the statement of condition at its fair value, removing from the statement of condition any asset or liability that was recorded to recognize the firm commitment and recording it as a gain or loss in current period earnings.

Embedded Derivatives. The Bank may issue debt, make advances, or purchase financial instruments in which a derivative instrument is embedded. Upon execution of these transactions, the Bank assesses whether the economic characteristics of the embedded derivative are clearly and closely related to the economic characteristics of the remaining component of the advance, debt, deposit, or other financial instrument (the host contract) and whether a separate, nonembedded instrument with the same terms as the embedded instrument would meet the definition of a derivative instrument. When the Bank determines that (1) the embedded derivative has economic characteristics that are not clearly and closely related to the economic characteristics of the host contract and (2) a separate, stand-alone instrument with the same terms would qualify as a derivative instrument, the embedded derivative is separated from the host contract, carried at fair value, and designated as a stand-alone derivative instrument. If the entire contract (the host contract and the embedded derivative) is to be measured at fair value, with changes in fair value reported in current earnings (for example, an investment security classified as trading, as well as hybrid financial instruments) or if the Bank cannot reliably identify and measure the embedded derivative for purposes of separating that derivative from its host contract, the entire contract is carried on the statement of condition at fair value and no portion of the contract is designated as a hedging instrument. The Bank has determined that all embedded derivatives in currently outstanding transactions as of September 30, 2011, are clearly and closely related to the host contracts, and therefore no embedded derivatives have been bifurcated from the host contract.

Credit Risk. The table below presents credit-risk exposure on derivative instruments, excluding instances where a counterparty's pledged cash collateral to the Bank exceeds the Bank's net position (dollars in thousands).

	September 30, 2011		December 31, 2010
Total net exposure at fair value(1)	$	28,924	$	17,098
Cash collateral held	12,511		2,280
Net exposure after collateral	$	16,413	$	14,818

_______________________

(1)  Includes net accrued interest receivable of $1.2 million and $2.2 million at September 30, 2011, and December 31, 2010, respectively.

Certain of the Bank's derivative instruments contain provisions that require the Bank to post additional collateral with its counterparties if there is deterioration in the Bank's credit ratings. Under the terms that govern such instruments, if the Bank's credit rating is lowered by an NRSRO, the Bank is required to deliver additional collateral on derivative instruments in a net liability position. In the event of a split among such credit ratings, the lower ratings govern. The aggregate fair value of all derivative instruments with credit-risk-related contingent features that were in a net liability position (before cash collateral and related accrued interest) at September 30, 2011, was $896.4 million for which the Bank had delivered collateral with a post-haircut value of $773.3 million in the normal course of business. The following table sets forth the post-haircut value of incremental collateral that certain swap counterparties could have required the Bank to deliver based on incremental credit rating downgrades at September 30, 2011.

Post-haircut Value of Incremental Collateral to be Delivered as of September 30, 2011 (dollars in thousands)
Ratings downgrade (1)
From	To	Incremental Collateral(2)
AA+	AA or AA-	$	40,000
AA-	A+, A or A-	55,598

_______________________

(1) Ratings are expressed in this table according to Standard & Poor's Rating Service's (S&P's) conventions but include the equivalent of such rating by Moody's Investor Services (Moody's).

(2) Additional collateral of $21.9 million is required as of September 30, 2011 at a rating of AA+ and is not included in the table.

The Bank executes derivatives with nonmember counterparties with long-term ratings of single-A (or equivalent) or better by S&P and Moody's at the time of the transaction, although risk-reducing trades may be approved for counterparties whose ratings have fallen below these ratings. Some of these counterparties or their affiliates buy, sell, and distribute COs. See Note 12 — Consolidated Obligations for additional information. Note 18 — Commitments and Contingencies discusses assets pledged by the Bank to these counterparties. The Bank is not a derivatives dealer and does not trade derivatives for short-term profit.

The loss recognized in accumulated other comprehensive loss for hedged items in cash-flow hedging relationships was $25.2 million for the three months ended September 30, 2011. The loss recognized in accumulated other comprehensive loss for hedged items in cash-flow hedging relationships was $26.8 million for the nine months ended September 30, 2011. The Bank had no derivatives and hedged items in cash-flow hedging relationships during the three and nine months ended September 30, 2010.

For the three and nine months ended September 30, 2011 and 2010, there were no reclassifications from other comprehensive loss into earnings as a result of the discontinuance of cash-flow hedges because the original forecasted transactions were not expected to occur by the end of the originally specified time period or within a two-month period thereafter.

As of September 30, 2011, none of the Bank's unrecognized net losses on derivative instruments accumulated in other comprehensive loss are expected to be reclassified to earnings during the next 12 months. The maximum length of time over which the Bank is hedging its exposure to the variability in future cash flows for forecasted transactions is three years.

The notional amount of derivatives serves as a factor in determining periodic interest payments or cash flows received and paid. However, the notional amount of derivatives represents neither the actual amounts exchanged nor the overall exposure of the Bank to credit and market risk. The risks of derivatives can be measured meaningfully on a portfolio basis that takes into account the derivatives, the item being hedged, and any offsets between the two.

The following table presents the fair value of derivative instruments as of September 30, 2011 (dollars in thousands):

Capital [Abstract]

Stockholders' Equity Note Disclosure [Text Block]

Capital

The Bank is subject to three capital requirements under its capital structure plan and Finance Agency rules and regulations:

1.Risk-based capital. Under this capital requirement, the Bank must maintain at all times permanent capital, defined as Class B stock and retained earnings, in an amount at least equal to the sum of its credit-risk capital requirement, its market-risk capital requirement, and its operations-risk capital requirement, calculated in accordance with Bank policy and Finance Agency rules and regulations, referred to herein as the risk-based capital requirement. Only permanent capital satisfies this risk-based capital requirement. The Finance Agency may require the Bank to maintain a greater amount of permanent capital than is required as defined by the risk-based capital requirements.

2.Total regulatory capital. Under this capital requirement, the Bank is required to maintain at all times a total capital-to-assets ratio of at least 4 percent. Total regulatory capital is the sum of permanent capital, any general loss allowance if consistent with GAAP and not established for specific assets, and other amounts from sources determined by the Finance Agency as available to absorb losses.

3.Leverage capital. Under this third capital requirement, the Bank is required to maintain at all times a leverage capital-to-assets ratio of at least 5 percent. A leverage capital-to-assets ratio is defined as permanent capital weighted 1.5 times divided by total assets.

Mandatorily redeemable capital stock, which is classified as a liability under GAAP, is considered capital for determining the Bank's compliance with its regulatory capital requirements.

The following tables demonstrate the Bank's compliance with its regulatory capital requirements at September 30, 2011, and December 31, 2010 (dollars in thousands):

Joint Capital Enhancement Agreement

The 12 FHLBanks entered into a Joint Capital Enhancement Agreement (the Capital Agreement), as amended, which is intended to enhance the capital position of each FHLBank. The intent of the Capital Agreement is to allocate that portion of each FHLBank's earnings historically paid to satisfy its REFCorp obligation to a separate retained earnings account at that FHLBank.

Because each FHLBank has been required to contribute 20 percent of its earnings toward payment of the interest on REFCorp bonds until the REFCorp obligation was satisfied, the Capital Agreement provides that, upon full satisfaction of the REFCorp obligation, each FHLBank will contribute 20 percent of its net income each quarter to a restricted retained earnings account until the balance of that account equals at least one percent of that FHLBank's average balance of outstanding consolidated obligations for the previous quarter. Restricted retained earnings are not available to pay dividends.

The FHLBanks subsequently amended their capital plans or capital plan submissions, as applicable, to implement the provisions of the Capital Agreement, and the Finance Agency approved the capital plan amendments on August 5, 2011.

On August 5, 2011, the Finance Agency certified that the FHLBanks have fully satisfied their REFCorp obligation. In accordance with the Capital Agreement, starting in the third quarter of 2011, each FHLBank is required to allocate 20 percent of its net income to a separate restricted retained earnings account. As of September 30, 2011, restricted retained earnings totaled $10.0 million.
