FEDERAL HOME LOAN BANK OF CINCINNATI

NOTES TO UNAUDITED FINANCIAL STATEMENTS

Background Information

The Federal Home Loan Bank of Cincinnati (the FHLB), a federally chartered corporation, is one of 11 District Federal Home Loan Banks (FHLBanks). The FHLBanks serve the public by enhancing the availability of credit for residential mortgages and targeted community development. The FHLB is regulated by the Federal Housing Finance Agency (Finance Agency).

Note 1 - Basis of Presentation

The accompanying interim financial statements of the FHLB have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP). The preparation of financial statements in accordance with GAAP requires management to make assumptions and estimates. These assumptions and estimates affect the reported amount of assets and liabilities, the disclosure of contingent assets and liabilities, and the reported amounts of income and expenses. Actual results could differ from these estimates. The interim financial statements presented are unaudited, but they include all adjustments (consisting of only normal recurring adjustments) which are, in the opinion of management, necessary for a fair statement of the financial condition, results of operations, and cash flows for such periods. These financial statements do not include all disclosures associated with annual financial statements and accordingly should be read in conjunction with the audited financial statements and notes included in the FHLB's Annual Report on Form 10-K for the year ended December 31, 2015 filed with the Securities and Exchange Commission (SEC). Results for the three months endedMarch 31, 2016 are not necessarily indicative of operating results for the full year.

The FHLB presents certain financial instruments, including derivative instruments and securities purchased under agreements to resell, on a net basis when it has a legal right of offset and all other requirements for netting are met (collectively referred to as the netting requirements). For these instruments, the FHLB has elected to offset its asset and liability positions, as well as cash collateral received or pledged, when it has met the netting requirements. The FHLB did not have any offsetting liabilities related to its securities purchased under agreements to resell for the periods presented.

The net exposure for these financial instruments can change on a daily basis; therefore, there may be a delay between the time this exposure change is identified and additional collateral is requested, and the time this collateral is received or pledged. Likewise, there may be a delay for excess collateral to be returned. For derivative instruments that meet the requirements for netting, any excess cash collateral received or pledged is recognized as a derivative liability or derivative asset. Additional information regarding these agreements is provided in Note 10. Based on the fair value of the related collateral held, the securities purchased under agreements to resell were fully collateralized for the periods presented. For more information about the FHLB's investments in securities purchased under agreements to resell, see “Item 8. Financial Statements and Supplementary Data - Note 1 - Summary of Significant Accounting Policies” in the FHLB's 2015 Annual Report on Form 10-K.

The FHLB has evaluated subsequent events for potential recognition or disclosure through the issuance of these financial statements and believes there have been no material subsequent events requiring additional disclosure or recognition in these financial statements.

Note 2 - Recently Issued Accounting Standards and Interpretations

Contingent Put and Call Options in Debt Instruments.On March 14, 2016, the Financial Accounting Standards Board (FASB) issued amendments to clarify the requirements for assessing whether contingent call (put) options that can accelerate the payment of principal on debt instruments are clearly and closely related to their debt hosts. The guidance requires entities to apply only the four-step decision sequence when assessing whether the economic characteristics and risks of call (put) options are clearly and closely related to the economic characteristics and risks of their debt hosts. Consequently, when a call (put) option is contingently exercisable, an entity does not have to assess whether the event that triggers the ability to exercise a call (put) option is related to interest rates or credit risks. This guidance becomes effective for the FHLB for the interim and annual periods beginning after December 15, 2016, and early adoption is permitted. The guidance should be applied on a modified retrospective basis to existing debt instruments as of the beginning of the period for which the amendments are effective. The FHLB is in the process of evaluating this guidance, and its effect on the FHLB's financial condition, results of operations, and cash flows has not yet been determined.

9

Effect of Derivative Contract Novations on Existing Hedge Accounting Relationships.On March 10, 2016, the FASB issued amendments to clarify that a change in the counterparty to a derivative instrument that has been designated as the hedging instrument under GAAP does not, in and of itself, require dedesignation of that hedging relationship provided that all other hedge accounting criteria continue to be met. This guidance becomes effective for the FHLB for the interim and annual periods beginning after December 15, 2016, and early adoption is permitted. The amendments provide entities with the option to apply the guidance using either a prospective approach or a modified retrospective approach, retrospectively applied to all derivative instruments that meet the specific conditions. The FHLB elected to early adopt the guidance prospectively on January 1, 2016. The adoption of this guidance had no effect on the FHLB's financial condition, results of operations, and cash flows.

Leases. On February 25, 2016, the FASB issued guidance which requires recognition of lease assets and lease liabilities on the Statement of Condition and disclosure of key information about leasing arrangements. In particular, this guidance requires a lessee, of operating or finance leases, to recognize on the Statement of Condition a liability to make lease payments and a right-of-use asset representing its right to use the underlying asset for the lease term. However, for leases with a term of 12 month or less, a lessee is permitted to make an accounting policy election not to recognize lease assets and lease liabilities.The guidance becomes effective for the FHLB for the interim and annual periods beginning after December 15, 2018, and early application is permitted. The guidance requires lessors and lessees to recognize and measure leases at the beginning of the earliest period presented in the financial statements using a modified retrospective approach. The FHLB is in the process of evaluating this guidance, and its effect on the FHLB's financial condition, results of operations, and cash flows has not yet been determined.

Recognition and Measurement of Financial Assets and Financial Liabilities. On January 5, 2016, the FASB issued amended guidance on certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. This guidance includes, but is not limited to, the following:

▪ Requires equity investments (with certain exceptions) to be measured at fair value with changes in fair value recognized in net income.

▪ Require an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected the fair value option.

▪ Requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset on the balance sheet or the accompanying notes to the financial statements.

▪ Eliminates the requirement for public entities to disclose the method(s) and significant assumptions used to estimate the fair value for financial instruments measured at amortized cost on the balance sheet.

The guidance becomes effective for the FHLB for the interim and annual periods beginning after December 15, 2017, and early adoption is only permitted for certain provision. The amendments, in general, should be applied by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the period of adoption. The FHLB is in the process of evaluating this guidance and its effect on the FHLB's financial condition, results of operations, and cash flows.

Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement. On April 15, 2015, the FASB issued amendments to clarify the accounting for cloud computing arrangements. The amendments provide guidance to customers on determining whether a cloud computing arrangement includes a software license. If the arrangement includes a software license, then the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If the arrangement does not contain a software license, the customer should account for the arrangement as a service contract. This guidance became effective for the FHLB for the interim and annual periods beginning on January 1, 2016, and was adopted prospectively. The adoption of this guidance had no material effect on the FHLB's financial condition, results of operations, and cash flows.

Simplifying the Presentation of Debt Issuance Costs. On April 7, 2015, the FASB issued guidance to simplify the presentation of debt issuance costs. This guidance requires that debt issuance costs related to a recognized debt liability be presented in the Statement of Condition as a direct deduction from the carrying amount of the liability, consistent with the presentation of debt discounts. This guidance became effective for the FHLB for the interim and annual periods beginning on January 1, 2016. As a result of adopting this guidance, unamortized concessions (in thousands) of $13,042 included in other assets at December 31, 2015 were reclassified as a reduction in the balance of the corresponding Consolidated Obligations. The reclassification resulted in a decrease (in thousands) of $13,042 in Consolidated Bonds at December 31, 2015. Accordingly, the FHLB's total assets and total liabilities each decreased by (in thousands) $13,042 at December 31, 2015. The adoption of this guidance had no effect on the FHLB's results of operations and cash flows.

Realized Gains and Losses. From time to time the FHLB may sell securities out of its held-to-maturity portfolio. These securities, generally, have less than 15 percent of the acquired principal outstanding at the time of the sale. These sales are considered maturities for the purposes of security classification. For the three months endedMarch 31, 2016 and 2015, the FHLB did not sell any held-to-maturity securities.

Note 6 - Other-Than-Temporary Impairment Analysis

The FHLB evaluates any of its individual available-for-sale and held-to-maturity investment securities holdings in an unrealized loss position for other-than-temporary impairment on a quarterly basis.

For its Other U.S. obligations and GSE investments (mortgage-backed securities and non-mortgage-backed securities), the FHLB has determined that the strength of the issuers' guarantees through direct obligations or support from the U.S. government is sufficient to protect the FHLB from losses based on current expectations. As a result, the FHLB determined that, as of March 31, 2016, all of the gross unrealized losses on these investments were temporary as the declines in market value of these securities were not attributable to credit quality. Furthermore, the FHLB does not intend to sell the investments, and it is not more likely than not that the FHLB will be required to sell the investments before recovery of their amortized cost bases. As a result, the FHLB did not consider any of these investments to be other-than-temporarily impaired at March 31, 2016.

The FHLB did not consider any of its investments to be other-than-temporarily impaired at December 31, 2015.

Note 7 - Advances

The FHLB offers a wide range of fixed- and variable-rate Advance products with different maturities, interest rates, payment characteristics and optionality. The following table presents Advance redemptions by contractual maturity, including index-amortizing Advances, which are presented according to their predetermined amortization schedules.

The FHLB offers certain fixed and variable-rate Advances to members that may be prepaid on specified dates (call dates) without incurring prepayment or termination fees (callable Advances). If the call option is exercised, replacement funding may be available. At March 31, 2016 and December 31, 2015, the FHLB had callable Advances (in thousands) of $14,731,435 and $14,095,712. Other Advances may only be prepaid subject to a prepayment fee paid to the FHLB that makes the FHLB financially indifferent to the prepayment of the Advance.

The FHLB also offers putable Advances. With a putable Advance, the FHLB effectively purchases put options from the member that allows the FHLB to terminate the Advance at predetermined dates. The FHLB normally would exercise its put option when interest rates increase relative to contractual rates. At March 31, 2016 and December 31, 2015, the FHLB had putable Advances, excluding those where the related put options have expired, totaling (in thousands) $1,033,900 and $1,046,400.

Note 9 - Allowance for Credit Losses

The FHLB has established an allowance methodology for each of the FHLB's portfolio segments: credit products (Advances, Letters of Credit and other extensions of credit to members); FHA mortgage loans held for portfolio; and conventional mortgage loans held for portfolio.

Credit products

The FHLB manages its credit exposure to credit products through an integrated approach that includes establishing a credit limit for each borrower, includes an ongoing review of each borrower's financial condition and is coupled with collateral and lending policies to limit risk of loss while balancing borrowers' needs for a reliable source of funding. In addition, the FHLB lends to eligible borrowers in accordance with federal statutes, including the FHLBank Act and Finance Agency regulations, which require the FHLB to obtain sufficient collateral to fully secure credit products. The estimated value of the collateral required to secure each member's credit products is calculated by applying collateral discounts, or haircuts, to the value of the collateral. The FHLB accepts certain investment securities, residential mortgage loans, deposits and other real estate related assets as collateral. In addition, community financial institutions are eligible to utilize expanded statutory collateral provisions

17

for small business, agriculture loans and community development loans. The FHLB's capital stock owned by its member borrowers is also pledged as collateral. Collateral arrangements and a member’s borrowing capacity vary based on the financial condition and performance of the institution, the types of collateral pledged and the overall quality of those assets. The FHLB can also require additional or substitute collateral to protect its security interest. Management of the FHLB believes that these policies effectively manage the FHLB's credit risk from credit products.

Members experiencing financial difficulties are subject to FHLB-performed “stress tests” of the impact of poorly performing assets on the member’s capital and loss reserve positions. Depending on the results of these tests and the level of overcollateralization, a member may be allowed to maintain pledged loan assets in its custody, may be required to deliver those loans into the custody of the FHLB or its agent, and/or may be required to provide details on these loans to facilitate an estimate of their fair value. The FHLB perfects its security interest in all pledged collateral. The FHLBank Act affords any security interest granted to the FHLB by a member priority over the claims or rights of any other party except for claims or rights of a third party that would be entitled to priority under otherwise applicable law and that are held by a bona fide purchaser for value or by a secured party holding a prior perfected security interest.

Using a risk-based approach, the FHLB considers the payment status, collateralization levels, and borrower's financial condition to be indicators of credit quality for its credit products. At March 31, 2016 and December 31, 2015, the FHLB had rights to collateral on a member-by-member basis with an estimated value in excess of its outstanding extensions of credit.

The FHLB evaluates and makes changes to its collateral guidelines, as necessary, based on current market conditions. At March 31, 2016 and December 31, 2015, the FHLB did not have any Advances that were past due, in non-accrual status or impaired. In addition, there were no troubled debt restructurings related to credit products of the FHLB during three months endedMarch 31, 2016 or 2015.

The FHLB has not experienced any credit losses on Advances since it was founded in 1932. Based upon the collateral held as security, its credit extension and collateral policies and the repayment history on credit products, the FHLB did not record any credit losses on credit products as of March 31, 2016 or December 31, 2015. Accordingly, the FHLB did not record any allowance for credit losses on Advances.

At March 31, 2016 and December 31, 2015, the FHLB did not record any liability to reflect an allowance for credit losses for off-balance sheet credit exposures. See Note 19 for additional information on the FHLB's off-balance sheet credit exposure.

MortgageLoans Held for Portfolio- FHA

The FHLB invests in fixed-rate mortgage loans secured by one-to-four family residential properties insured by the FHA. The FHLB expects to recover any losses from such loans from the FHA. Any losses from these loans that are not recovered from the FHA would be due to a claim rejection by the FHA and, as such, would be recoverable from the selling participating financial institutions. Therefore, the FHLB only has credit risk for these loans if the seller or servicer fails to pay for losses not covered by the FHA insurance. As a result, the FHLB did not establish an allowance for credit losses on its FHA insured mortgage loans. Furthermore, due to the insurance, none of these mortgage loans have been placed on non-accrual status.

Mortgage Loans Held for Portfolio - Conventional Mortgage Purchase Program (MPP)

The FHLB determines the allowance for conventional loans through analyses that include consideration of various data observations such as past performance, current performance, loan portfolio characteristics, collateral-related characteristics, industry data, and prevailing economic conditions. The measurement of the allowance for credit losses consists of: (1) collectively evaluating homogeneous pools of residential mortgage loans; (2) reviewing specifically identified loans for impairment; and (3) considering other relevant qualitative factors.

Collectively Evaluated Mortgage Loans. The credit risk analysis of conventional loans evaluated collectively for impairment considers historical delinquency migration, applies estimated loss severities, and incorporates the associated credit enhancements in order to determine the FHLB's best estimate of probable incurred losses at the reporting date. The FHLB performs the credit risk analysis of all conventional mortgage loans at the individual Master Commitment Contract level to properly determine the credit enhancements available to recover losses on loans under each individual Master Commitment Contract. The Master Commitment Contract is an agreement with a member in which the member agrees to make a best efforts attempt to sell a specific dollar amount of loans to the FHLB generally over a one-year period. Migration analysis is a methodology for determining, through the FHLB's experience over a historical period, the rate of default on loans. The FHLB applies migration analysis to loans based on payment status categories such as current, 30, 60, and 90 days past due. The FHLB then estimates, based on historical experience, how many loans in these categories may migrate to a loss realization event and

18

applies a current loss severity to estimate losses. The estimated losses are then reduced by the probable cash flows resulting from available credit enhancements. Any credit enhancement cash flows that are projected and assessed as not probable of receipt do not reduce estimated losses.

Individually Evaluated Mortgage Loans. Conventional mortgage loans that are considered troubled debt restructurings are specifically identified for purposes of calculating the allowance for credit losses. The FHLB measures impairment of these specifically identified loans by either estimating the present value of expected cash flows, estimating the loan's observable market price, or estimating the fair value of the collateral if the loan is collateral dependent. The FHLB removes specifically identified loans evaluated for impairment from the collectively evaluated mortgage loan population.

Qualitative Factors. The FHLB also assesses other qualitative factors in its estimation of loan losses for the collectively evaluated population. This amount represents a subjective management judgment, based on facts and circumstances that exist as of the reporting date, that is intended to cover other incurred losses that may not otherwise be captured in the methodology described above.

Rollforward of Allowance for Credit Losses on Mortgage Loans. The following tables present a rollforward of the allowance for credit losses on conventional mortgage loans as well as the recorded investment in mortgage loans by impairment methodology. The recorded investment in a loan is the unpaid principal balance of the loan adjusted for accrued interest, unamortized premiums or discounts, hedging basis adjustments and direct write-downs. The recorded investment is not net of any allowance.

Credit Enhancements. The conventional mortgage loans under the MPP are supported by some combination of credit enhancements (primary mortgage insurance (PMI), supplemental mortgage insurance (SMI) and the Lender Risk Account (LRA), including pooled LRA for those members participating in an aggregated MPP pool). The amount of credit enhancements needed to protect the FHLB against credit losses is determined through use of a third-party default model. These credit enhancements apply after a homeowner's equity is exhausted. Beginning in February 2011, the FHLB discontinued the use of SMI for all new loan purchases and replaced it with expanded use of the LRA. The LRA is funded by the FHLB as a portion of the purchase proceeds to cover expected losses. The LRA is recorded in other liabilities in the Statements of Condition. Excess funds over required balances are distributed to the member in accordance with a step-down schedule that is established upon execution of a Master Commitment Contract, subject to performance of the related loan pool. The LRA established for a pool of loans is limited to only covering losses of that specific pool of loans.

Troubled Debt Restructurings. A troubled debt restructuring is considered to have occurred when a concession is granted to a borrower for economic or legal reasons related to the borrower's financial difficulties and that concession would not have been considered otherwise. The FHLB's troubled debt restructurings primarily involve loans where an agreement permits the recapitalization of past due amounts up to the original loan amount and certain loans discharged in Chapter 7 bankruptcy. A loan considered a troubled debt restructuring is individually evaluated for impairment when determining its related allowance for credit losses. Credit loss is measured by factoring in expected cash shortfalls as of the reporting date.

The FHLB's recorded investment in modified loans considered troubled debt restructurings was (in thousands) $9,733 and $9,385 at March 31, 2016 and December 31, 2015, respectively. The amount of troubled debt restructurings is not considered material to the FHLB's financial condition, results of operations, or cash flows.

Note 10 - Derivatives and Hedging Activities

Nature of Business Activity

The FHLB is exposed to interest rate risk primarily from the effect of interest rate changes on its interest-earning assets and on the interest-bearing liabilities that finance these assets. The goal of the FHLB's interest-rate risk management strategy is not to eliminate interest-rate risk, but to manage it within appropriate limits. To mitigate the risk of loss, the FHLB has established policies and procedures, which include guidelines on the amount of exposure to interest rate changes it is willing to accept. In addition, the FHLB monitors the risk to its interest income, net interest margin and average maturity of interest-earning assets and interest-bearing liabilities. See Note 11 - Derivatives and Hedging Activities in the FHLB's 2015 Annual Report on Form 10-K for additional information on the FHLB's derivative transactions.

The FHLB uses derivatives when they are considered to be the most cost-effective alternative to achieve the FHLB's financial and risk management objectives. The FHLB re-evaluates its hedging strategies from time to time and may change the hedging techniques it uses or adopt new strategies.

The FHLB transacts its derivatives with large banks and major broker-dealers. Some of these banks and broker-dealers or their affiliates buy, sell, and distribute Consolidated Obligations. Derivative transactions may be either executed with a counterparty (uncleared derivatives) or cleared through a Futures Commission Merchant (i.e., clearing agent) with a Derivative Clearing Organization (cleared derivatives).

22

Once a derivative transaction has been accepted for clearing by a Derivative Clearing Organization (Clearinghouse), the derivative transaction is novated and the executing counterparty is replaced with the Clearinghouse. The FHLB is not a derivative dealer and does not trade derivatives for short-term profit.

Financial Statement Effect and Additional Financial Information

The notional amount of derivatives serves as a factor in determining periodic interest payments or cash flows received and paid. The notional amount reflects the FHLB's involvement in the various classes of financial instruments and represents neither the actual amounts exchanged nor the overall exposure of the FHLB to credit and market risk; the overall risk is much smaller. The risks of derivatives only can be measured meaningfully on a portfolio basis that takes into account the derivatives, the items being hedged and any offsets between the derivatives and the items being hedged.

Table 10.1 summarizes the fair value of derivative instruments, including the effect of netting adjustments and cash collateral. For purposes of this disclosure, the derivative values include the fair value of derivatives and the related accrued interest.

Credit Risk on Derivatives

The FHLB is subject to credit risk due to the risk of non-performance by counterparties to its derivative transactions and manages credit risk through credit analysis, collateral requirements and adherence to the requirements set forth in its policies, U.S. Commodity Futures Trading Commission regulations, and Finance Agency regulations. For uncleared derivatives, the degree of credit risk depends on the extent to which master netting arrangements are included in these contracts to mitigate the risk. The FHLB requires collateral agreements with collateral delivery thresholds on the majority of its uncleared derivatives.

For cleared derivatives, the Clearinghouse is the FHLB's counterparty. The Clearinghouse notifies the clearing agent of the required initial and variation margin and the clearing agent in turn notifies the FHLB. The requirement that the FHLB post initial and variation margin through the clearing agent, to the Clearinghouse, exposes the FHLB to credit risk if the clearing

24

agent or the Clearinghouse fails to meet its obligations. The use of cleared derivatives is intended to mitigate credit risk exposure because a central counterparty is substituted for individual counterparties and collateral for changes in the value of cleared derivatives is posted daily through a clearing agent.

The FHLB has analyzed the enforceability of offsetting rights incorporated in its cleared derivative transactions and determined that the exercise of those offsetting rights by a non-defaulting party under these transactions should be upheld under applicable law upon an event of default including bankruptcy, insolvency, or similar proceeding involving the Clearinghouse or the FHLB's clearing agent, or both. Based on this analysis, the FHLB presents a net derivative receivable or payable for all of its transactions through a particular clearing agent with a particular Clearinghouse.

Certain of the FHLB's uncleared derivative contracts contain provisions that require the FHLB to post additional collateral with its counterparties if there is deterioration in the FHLB's credit ratings. The aggregate fair value of all uncleared derivatives with credit-risk-related contingent features that were in a net liability position (before cash collateral and related accrued interest) at March 31, 2016 was (in thousands) $66,838, for which the FHLB had posted collateral with a fair value of (in thousands) $35,390 in the normal course of business.

If one of the FHLB's credit ratings had been lowered to the next lower rating that would have triggered additional collateral to be delivered, the FHLB would have been required to deliver up to an additional (in thousands) $5,864 of collateral at fair value to its derivatives counterparties at March 31, 2016.

For cleared derivatives, the Clearinghouse determines initial margin requirements and generally credit ratings are not factored into the initial margin. However, clearing agents may require additional initial margin to be posted based on credit considerations, including, but not limited to, credit rating downgrades. At March 31, 2016, the FHLB was not required to post additional initial margin by its clearing agents based on credit considerations.

Offsetting of Derivative Assets and Derivative Liabilities

The FHLB presents derivative instruments, related cash collateral, including initial and variation margin, received or pledged, and associated accrued interest, on a net basis by clearing agent and/or by counterparty when it has met the netting requirements.

25

Table 10.4 presents separately the fair value of derivative instruments meeting or not meeting netting requirements, including the related collateral received from or pledged to counterparties. At March 31, 2016 and December 31, 2015, the FHLB did not receive or pledge any non-cash collateral. Any overcollateralization under an individual clearing agent and/or counterparty level is not included in the determination of the net unsecured amount.

Note 16 - Pension and Postretirement Benefit Plans

Qualified Defined Benefit Multi-employer Plan. The FHLB participates in the Pentegra Defined Benefit Plan for Financial Institutions (Pentegra Defined Benefit Plan), a tax-qualified defined benefit pension plan. Under the Pentegra Defined Benefit Plan, contributions made by one participating employer may be used to provide benefits to employees of other participating employers because assets contributed by an employer are not segregated in a separate account or restricted to provide benefits only to employees of that employer. Also, in the event a participating employer is unable to meet its contribution requirements, the required contributions for the other participating employers could increase proportionately. The Pentegra Defined Benefit Plan covers substantially all officers and employees of the FHLB who meet certain eligibility requirements. Contributions to the Pentegra Defined Benefit Plan charged to compensation and benefit expense were $1,685,000 and $1,500,000 in the three months endedMarch 31, 2016 and 2015, respectively.

Qualified Defined Contribution Plan. The FHLB also participates in the Pentegra Defined Contribution Plan for Financial Institutions, a tax-qualified, defined contribution pension plan. The FHLB 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 FHLB contributed $387,000 and $374,000 in the three months endedMarch 31, 2016 and 2015, respectively.

Nonqualified Supplemental Defined Benefit Retirement Plan. The FHLB maintains a nonqualified, unfunded defined benefit plan. The plan ensures that participants receive the full amount of benefits to which they would have been entitled under the qualified defined benefit plan in the absence of limits on benefit levels imposed by the IRS. There are no funded plan assets. The FHLB has established a grantor trust, which is included in held-to-maturity securities on the Statements of Condition, to meet future benefit obligations and current payments to beneficiaries.

Postretirement Benefits Plan. The FHLB also sponsors a postretirement benefits plan that includes health care and life insurance benefits for eligible retirees. Future retirees are eligible for the postretirement benefits plan if they were hired prior to August 1, 1990, are age 55 or older, and their age plus years of continuous service at retirement are greater than or equal to 80. Spouses are covered subject to required contributions. There are no funded plan assets that have been designated to provide postretirement benefits.

Note 17 - Segment Information

The FHLB has identified two primary operating segments based on its method of internal reporting: Traditional Member Finance and the MPP. These segments reflect the FHLB's two primary Mission Asset Activities and the manner in which they are managed from the perspective of development, resource allocation, product delivery, pricing, credit risk and operational administration. The segments identify the principal ways the FHLB provides services to member stockholders.

Note 18 - Fair Value Disclosures

The fair value amounts recorded on the Statements of Condition and presented in the related note disclosures have been determined by the FHLB using available market information and the FHLB's best judgment of appropriate valuation methods. The fair values reflect the FHLB's judgment of how a market participant would estimate the fair values.

Fair Value Hierarchy. The FHLB records trading securities, available-for-sale securities, derivative assets, derivative liabilities, certain Advances and certain Consolidated Obligation Bonds at fair value on a recurring basis, and on occasion, certain mortgage loans held for portfolio on a nonrecurring basis. GAAP establishes a fair value hierarchy and requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The inputs are evaluated and an overall level for the measurement is determined. This overall level is an indication of how market observable the fair value measurement is. An entity must disclose the level within the fair value hierarchy in which the measurements are classified.

The fair value hierarchy prioritizes the inputs used to measure fair value into three broad levels:

Level 1 Inputs - Quoted prices (unadjusted) for identical assets or liabilities in an active market that the reporting entity can access on the measurement date.

Level 2 Inputs - Inputs other than quoted prices within Level 1 that are observable inputs for the asset or liability, either directly or indirectly. If the asset or liability has a specified (contractual) term, a Level 2 input must be observable for substantially the full term of the asset or liability. Level 2 inputs include the following: (1) quoted prices for similar assets or liabilities in active markets; (2) quoted prices for identical or similar assets or liabilities in markets that are not active; (3) inputs other than quoted prices that are observable for the asset or liability (e.g., interest rates and yield curves that are observable at commonly quoted intervals, and implied volatilities); and (4) inputs that are derived principally from or corroborated by observable market data by correlation or other means.

Level 3 Inputs - Unobservable inputs for the asset or liability.

The FHLB reviews the fair value hierarchy classifications on a quarterly basis. Changes in the observability of the valuation inputs may result in a reclassification of certain financial assets or liabilities. Such reclassifications are reported as transfers in/out at fair value as of the beginning of the quarter in which the changes occur. The FHLB did not have any transfers of assets or liabilities recorded at fair value on a recurring basis during the three months endedMarch 31, 2016 or 2015.

Table 18.1 presents the carrying value, fair value, and fair value hierarchy of financial assets and liabilities of the FHLB. These values do not represent an estimate of the overall market value of the FHLB as a going concern, which would take into account future business opportunities and the net profitability of assets versus liabilities.

Fair Value Option. The fair value option provides an irrevocable option to elect fair value as an alternative measurement for selected financial assets, financial liabilities, unrecognized firm commitments, and written loan commitments not previously carried at fair value. It requires a company to display the fair value of those assets and liabilities for which it has chosen to use fair value on the face of the Statements of Condition. Fair value is used for both the initial and subsequent measurement of the designated assets, liabilities and commitments, with the changes in fair value recognized in net income. If elected, interest income and interest expense on Advances and Consolidated Bonds carried at fair value are recognized based solely on the contractual amount of interest due or unpaid. Any transaction fees or costs are immediately recognized into other non-interest income or other non-interest expense.

The FHLB has elected the fair value option for certain financial instruments that either do not qualify for hedge accounting or may be at risk for not meeting hedge effectiveness requirements. These fair value elections were made primarily in an effort to mitigate the potential income statement volatility that can arise from economic hedging relationships in which the carrying value of the hedged item is not adjusted for changes in fair value.

Total changes in fair value included in current period earnings	$	234	$	(19,586	)	$	203	$	(5,002	)

For instruments recorded under the fair value option, the related contractual interest income and contractual interest expense are recorded as part of net interest income on the Statements of Income. The remaining changes in fair value for instruments in which the fair value option has been elected are recorded as “Net losses on financial instruments held under fair value option” in the Statements of Income. The FHLB has determined that no adjustments to the fair values of its instruments recorded under the fair value option for instrument-specific credit risk were necessary as of March 31, 2016 or December 31, 2015.

The following table reflects the difference between the aggregate unpaid principal balance outstanding and the aggregate fair value for Advances and Consolidated Bonds for which the fair value option has been elected.

Legal Proceedings. From time to time, the FHLB is subject to legal proceedings arising in the normal course of business. In March 2010, the FHLB was advised by representatives of the Lehman Brothers Holdings, Inc. bankruptcy estate that they believed that the FHLB had been unjustly enriched in connection with the close out of its interest rate swap transactions with Lehman at the time of the Lehman bankruptcy in 2008 and that the bankruptcy estate was entitled to the $43 million difference between the settlement amount the FHLB paid Lehman in connection with the close-out transactions and the market value payment the FHLB received when replacing the swaps with other counterparties. In May 2010, the FHLB received a Derivatives Alternative Dispute Resolution notice from the Lehman bankruptcy estate with a settlement demand of $65.8 million, plus interest accruing primarily at LIBOR plus 14.5 percent since the bankruptcy filing, based on their view of how the settlement amount should have been calculated. In accordance with the Alternative Dispute Resolution Order of the Bankruptcy Court administering the Lehman estate, senior management of the FHLB participated in a non-binding mediation in New York in August 2010, and counsel for the FHLB continued discussions with the court-appointed mediator for several weeks thereafter. The mediation concluded in October 2010 without a settlement of the claims asserted by the Lehman bankruptcy estate. In April 2013, Lehman Brothers Special Financing Inc., through Lehman Brothers Holdings Inc. and the Plan Administrator under the Modified Third Amended Joint Chapter 11 Plan of Lehman Brothers Holdings Inc. and its Affiliated Debtors, filed an adversary complaint in the United States Bankruptcy Court for the Southern District of New York against the FHLB seeking (a) a declaratory judgment on the interpretation of certain provisions and the calculation of amounts due under the agreement governing the 2008 swap transactions described above, and (b) additional amounts alleged as due as part of the termination of such transactions. The FHLB believes that it correctly calculated, and fully satisfied its obligation to Lehman in September 2008, and the FHLB intends to vigorously defend itself.

The FHLB also is subject to other legal proceedings arising in the normal course of business. The FHLB would record an accrual for a loss contingency when it is probable that a loss has been incurred and the amount can be reasonably estimated. After consultation with legal counsel, management does not anticipate that the ultimate liability, if any, arising out of these matters will have a material effect on the FHLB's financial condition or results of operations.

Note 20 - Transactions with Other FHLBanks

The FHLB notes all transactions with other FHLBanks on the face of its financial statements. Occasionally, the FHLB loans short-term funds to and borrows short-term funds from other FHLBanks. These loans and borrowings are transacted at then current market rates when traded. There were no such loans or borrowings outstanding at March 31, 2016 or December 31, 2015 and no such transactions occurred during the three months endedMarch 31, 2016 and 2015.

In addition, the FHLB may, from time to time, assume the outstanding primary liability for Consolidated Obligations of another FHLBank (at then current market rates on the day when the transfer is traded) rather than issuing new debt for which the FHLB is the primary obligor. The FHLB then becomes the primary obligor on the transferred debt. There were no Consolidated Obligations transferred to the FHLB during the three months endedMarch 31, 2016 or 2015. The FHLB had no Consolidated Obligations transferred to other FHLBanks during these periods.

Note 21 - Transactions with Stockholders

Transactions with Directors' Financial Institutions. In the ordinary course of its business, the FHLB may provide products and services to members whose officers or directors serve as directors of the FHLB (Directors' Financial Institutions). Finance Agency regulations require that transactions with Directors' Financial Institutions be made on the same terms as those with any other member. The following table reflects balances with Directors' Financial Institutions for the items indicated below. The FHLB had no mortgage-backed securities or derivatives transactions with Directors' Financial Institutions at March 31, 2016 or December 31, 2015.

Nonmember Affiliates. The FHLB has relationships with three nonmember affiliates, the Kentucky Housing Corporation, the Ohio Housing Finance Agency and the Tennessee Housing Development Agency. The FHLB had no investments in or borrowings to any of these nonmember affiliates at March 31, 2016 or December 31, 2015. The FHLB has executed standby bond purchase agreements with one state housing authority whereby the FHLB, for a fee, agrees as a liquidity provider if required, to purchase and hold the authority's bonds until the designated marketing agent can find a suitable investor or the housing authority repurchases the bond according to a schedule established by the standby agreement. During the first three months of 2016 and 2015, the FHLB was not required to purchase any bonds under these agreements.

Item 2.    Management's Discussion and Analysis of Financial Condition and Results of Operations.

This document contains forward-looking statements that describe the objectives, expectations, estimates, and assessments of the Federal Home Loan Bank of Cincinnati (the FHLB).

In the first quarter of 2016, the FHLB fulfilled its mission by providing readily available and competitively priced wholesale funding to its member financial institutions, supporting its commitment to affordable housing, and paying stockholders a competitive dividend return on their capital investment.

The balance of Mission Asset Activity – which we define as Advances, Letters of Credit, and total MPP (including purchase commitments) – was $93.9 billion at March 31, 2016, a decrease of $7.1 billion (seven percent) from year-end 2015. This change was primarily driven by a decrease in the balances of Advances and Letters of Credit. The decline in Advances was primarily due to a final rule issued in January 2016 by the Federal Housing Finance Agency (Finance Agency) that banned captive insurance companies as eligible members in an FHLBank.

As of March 31, 2016, members funded on average 3.0 percent of their assets with Advances, and the market penetration rate was relatively stable with approximately 70 percent of members holding Mission Asset Activity. Most members continued to have modest demand for new Advance borrowings due to measured economic growth, an abundance of deposits, and significant amounts of liquidity made available as a result of the actions of the Federal Reserve System.

The principal balance of mortgage loans held for portfolio at March 31, 2016rose$0.3 billion (four percent) from year-end 2015. The growth reflected ongoing improvements in the housing market and low mortgage rates as well as our strategy to increase this segment. During the first quarter of 2016, we purchased $0.5 billion of mortgage loans, while principal reductions totaled $0.2 billion. Residual credit risk exposure in the mortgage loan portfolio continued to be minimal.

Based on earnings in the first quarter of 2016, we contributed $6 million to the Affordable Housing Program (AHP) pool of funds to be awarded to members in 2017. In addition, we continued our voluntary sponsorship of two other housing programs, which provide resources to pay for accessibility rehabilitation and emergency repairs for special needs and elderly homeowners and to help members aid their communities following natural disasters.

Investments and Other Assets

The balance of investments at March 31, 2016 was $26.7 billion, a decrease of $10.7 billion (29 percent) from year-end 2015. Most of the decrease was driven by a decline in short-term investments used for asset liquidity, for which we carried a larger than normal balance at the end of 2015. At March 31, 2016, investments included $15.4 billion of mortgage-backed securities and $11.3 billion of other investments, which were mostly short-term instruments held for liquidity.

Investment balances averaged $31.1 billion in the first three months of 2016, an increase of $4.8 billion (18 percent) from the average balance during the same period of 2015. This primarily reflected an increase in average liquidity investments between these two periods. All of our mortgage-backed securities held at March 31, 2016 were issued and guaranteed by Fannie Mae,

42

Freddie Mac or a U.S. agency. We maintained an adequate amount of asset liquidity throughout the first three months of 2016 under a variety of liquidity measures as discussed in the "Liquidity Risk" section of "Quantitative and Qualitative Disclosures About Risk Management."

Capital

Capital adequacy remained strong in the first three months of 2016, surpassing all minimum regulatory capital requirements. The GAAP capital-to-assets ratio at March 31, 2016 was 4.78 percent, while the regulatory capital-to-assets ratio was 4.89 percent. Both ratios exceeded the regulatory required minimum of four percent. Regulatory capital includes mandatorily redeemable capital stock accounted for as a liability under GAAP. The amounts of GAAP and regulatory capital decreased$214 million and $149 million, respectively, in the first three months of 2016, due primarily to repurchases of certain members' excess capital stock.

Total retained earnings were $770 million at March 31, 2016, an increase of $5 million (one percent) from year-end 2015. We believe the amount of retained earnings is sufficient to protect against members' impairment risk of their capital stock investment in the FHLB and to provide the opportunity to stabilize or augment future dividends, if needed. Our Capital Plan also has safeguards to prevent financial leverage ratios from falling below regulatory minimum levels.

Results of Operations

Overall Results

The table below summarizes our results of operations.

	Three Months Ended March 31,						Year Ended December 31,
(Dollars in millions)	2016			2015			2015
Net income	$	48		$	61		$	249
Affordable Housing Program accrual	6			7			28
Return on average equity (ROE)	3.83		%	4.97		%	4.90		%
Return on average assets	0.17			0.24			0.24
Weighted average dividend rate	4.00			4.00			4.00
Average 3-month LIBOR	0.62			0.26			0.32
ROE spread to 3-month LIBOR	3.21			4.71			4.58
Dividend rate spread to 3-month LIBOR	3.38			3.74			3.68

Net income decreased $13 million (21 percent) in the first three months of 2016 compared to the same period in 2015. The reduction in net income does not represent a negative trend in profitability. Most of the reduction was due to unrealized losses from changes in market values on certain Consolidated Obligations held at fair value, net of derivatives used to hedge these Obligations. These unrealized losses will be reversed in the future as unrealized gains since Obligations, and any related derivatives, mature at par value.

We believe that our financial condition will continue to generate a steady economic operating performance, reflecting the combined impact of a stable business and interest rate environment, favorable spreads on interest-earnings assets, a relatively constant composition of assets, a consistent and conservative management of risk, a moderate increase in operating expenses, and a prudent economic use of derivative transactions. Additionally, our business model is structured to be able to absorb sharp changes in Mission Asset Activity because we can undertake commensurate reductions in liability balances and capital.

The spread between ROE and 3-month LIBOR is a market benchmark we believe member stockholders use to assess the competitiveness of the return on their capital investment in our company. Earnings continued to be sufficient to represent competitive returns on stockholders' capital investment. Consistent with experience over the last several years, ROE was significantly above short-term rates, resulting in the ROE spreads being wider than the long-term historical average spread.

In March 2016, we paid stockholders a quarterly 4.00 percent annualized dividend rate on their capital investment in our company. This is the same rate we have distributed in each of the last ten quarters.

Effect of Interest Rate Environment

Trends in market interest rates strongly influence the results of operations via how they affect members' demand for Mission Asset Activity, spreads on assets, funding costs and decisions in managing the tradeoffs in our market risk/return profile. The following table presents key market interest rates (obtained from Bloomberg L.P.).

	Quarter 1 2016				Year 2015				Quarter 1 2015
	Ending		Average		Ending		Average		Ending		Average
Federal funds effective	0.25	%	0.36	%	0.20	%	0.13	%	0.06	%	0.11	%
3-month LIBOR	0.63		0.62		0.61		0.32		0.27		0.26
2-year LIBOR	0.84		0.91		1.18		0.88		0.81		0.84
10-year LIBOR	1.64		1.78		2.19		2.18		2.02		2.09
2-year U.S. Treasury	0.72		0.84		1.05		0.67		0.56		0.59
10-year U.S. Treasury	1.77		1.92		2.27		2.13		1.92		1.97

30-year mortgage current coupon (1)	2.59		2.71		3.02		2.88		2.68		2.71

(1) Simple average of current coupon rates of Fannie Mae and Freddie Mac par mortgage-backed security indications.

The persistence of the low interest rate environment in the first three months of 2016 continued to favorably affect our overall results of operations relative to the level of interest rates. Interest rates remained very low by historical standards in the first quarter of 2016.

Effect of Economy and Financial Markets on Mission Asset Activity

In the last several years, the percentage of assets that members funded with Advances showed little variation, in the range of three to four percent. We would expect to see a broad-based increase in Advance demand when the economy experiences an improved growth trend, when interest rates begin to increase over time, or if changes in Federal Reserve policy reduce other sources of liquidity available to members.

The relative balance between loan and deposit fluctuations can provide an indication of potential member Advance demand. From December 31, 2014 to December 31, 2015 (the most recent period for which data are available), aggregate loan portfolios of Fifth District depository institutions grew $117.5 billion (9.1 percent) while their aggregate deposit balances fell $92.3 billion (4.2 percent). Most of the loan growth and deposit decline in this period occurred from our largest members, which is consistent with the concentration of financial activity.

Excluding the five members with over $50 billion of assets, aggregate loans increased $14.2 billion (7.1 percent) in the 12-month period while aggregate deposits grew by $12.5 billion (5.2 percent).

Business Outlook and Risk Management

Our major business strategies, outlook for our business, and risk profiles and management have not changed substantially since our 2015 Annual Report on Form 10-K. “Quantitative and Qualitative Disclosures About Risk Management” provides details on current risk exposures. We have no material updates to provide for the regulatory or legislative environment since the 2015 Annual Report on Form 10-K.

ANALYSIS OF FINANCIAL CONDITION

Mission Asset Activity

Mission Assets are the primary means by which we fulfill our mission with direct connections to members. We regularly monitor the balance sheet concentration of Mission Asset Activity. In the first three months of 2016, our Primary Mission Asset ratio, which measures the sum of average Advances and mortgage loans as a percentage of average Consolidated Obligations, was 76 percent. This ratio exceeded the Finance Agency's preferred ratio of 70 percent. In assessing overall mission achievement, we also consider supplemental sources of Mission Asset Activity, the most significant of which is Letters of Credit issued to members.

Credit Services

Credit Activity and Advance Composition

The table below shows trends in Advance balances by major programs and in the notional amount of Letters of Credit.

(Dollars in millions)	March 31, 2016				December 31, 2015				March 31, 2015
	Balance		Percent(1)		Balance		Percent(1)		Balance		Percent(1)

Letters of Credit (notional)	$	16,757			$	19,555			$	16,905

(1) As a percentage of total Advances principal.    

(2) Excludes Putable Advances where the related put options have expired. Such Advances are classified based on their current terms.

The modest decline in Advance balances in the first three months of 2016 was driven by reductions from a few large members along with reductions in short-term repurchase (REPO) Advance borrowings primarily by captive insurance company members that are required to be paid off by February 2017 due to the Finance Agency's 2016 final rule on membership requirements. REPO Advances, because of their short-term maturities, typically represent our most volatile Advance product by balance.

Members reduced their available lines in the Letters of Credit program by $2.8 billion (14 percent) in the first three months of 2016. Letters of Credit balances averaged $17.2 billion in the first three months of 2016, an increase of $0.3 billion (two percent) from the average balance during the same period in 2015. We normally earn fees on Letters of Credit based on the actual average amount of the Letters utilized, which generally is less than the notional amount issued.

Advance Usage

In addition to analyzing Advance balances by dollar trends and the number of members utilizing them, we monitor the degree to which members use Advances to fund their balance sheets. The following table shows the unweighted, average ratio of each member's Advance balance to its most-recently available figures for total assets.

	March 31, 2016		December 31, 2015
Average Advances-to-Assets for Members
Assets less than $1.0 billion (621 members)	2.92	%	3.26	%
Assets over $1.0 billion (78 members)	3.19		4.35
All members	2.95		3.37

45

Advance usage ratios were lower in the first quarter of 2016, which was the result of reductions in the balances of certain large members, decreases in short-term borrowings from several captive insurance company members as discussed above, and normal fluctuations.

The following tables present principal balances for the five members with the largest Advance borrowings.

(Dollars in millions)
March 31, 2016					December 31, 2015
Name	Par Value of Advances		Percent of Total Par Value of Advances		Name	Par Value of Advances		Percent of Total Par Value of Advances
JPMorgan Chase Bank, N.A.	$	33,300	49	%	JPMorgan Chase Bank, N.A.	$	35,350	48	%
U.S. Bank, N.A.	10,743		16		U.S. Bank, N.A.	10,086		14
Nationwide Life Insurance Company	2,302		3		Capstead Insurance, LLC	2,875		4
Third Federal Savings and Loan Association	2,283		3		Nationwide Life Insurance Company	2,279		3

Total of Top 5	$	50,647	74	%	Total of Top 5	$	52,752	72	%

Advance concentration ratios are influenced by, and generally similar to, concentration ratios of financial activity among our Fifth District financial institutions. We believe that having large financial institutions that actively use our Mission Asset Activity augments the value of membership to all members. For example, such activity improves our operating efficiency, increases our earnings and thereby contributions to housing and community investment programs, may enable us over time to obtain more favorable funding costs, and helps us maintain competitively priced Mission Asset Activity.

Mortgage Loans Held for Portfolio (Mortgage Purchase Program, or "MPP")

The table below shows principal purchases and reductions of loans in the MPP for the first three months of 2016.

(In millions)	MPP Principal
Balance at December 31, 2015	$	7,758
Principal purchases	538
Principal reductions	(258		)
Balance at March 31, 2016	$	8,038

The increase in principal loan balance in the first quarter of 2016 resulted primarily from our two largest sellers who drive program balances. In the first three months of 2016, 76 members sold us mortgage loans, with the number of monthly sellers averaging 59. All loans acquired in the first quarter of 2016 were conventional loans.We closely track the refinancing incentives of our mortgage assets (including loans in the MPP and mortgage-backed securities) because the option for homeowners to change their principal payments normally represents a large portion of our market risk exposure. MPP principal paydowns in the first three months of 2016 equated to a nine percent annual constant prepayment rate, down from the 14 percent rate for all of 2015 as higher rates towards the end of 2015 and first part of 2016 resulted in reduced refinancing incentives for many of our mortgage assets.

The MPP's composition of balances by loan type, original final maturity, and weighted-average mortgage note rate did not change materially in the first three months of 2016. The weighted average mortgage note rate fell from 4.14 percent at the end of 2015 to 4.11 percent at March 31, 2016. This decline reflected a continuing trend of prepayments of higher rate mortgages and purchases of lower rate mortgages. MPP yields earned during the first three months of 2016, after consideration of funding costs, continued to offer favorable returns relative to their market risk exposure.

Investments

The table below presents the ending and average balances of the investment portfolio.

(In millions)	Three Months Ended				Year Ended
	March 31, 2016				December 31, 2015
	Ending Balance		Average Balance		Ending Balance		Average Balance
Liquidity investments	$	11,336	$	15,802	$	22,110	$	12,590
Mortgage-backed securities	15,369		15,195		15,246		14,664
Other investments (1)	—		119		—		85
Total investments	$	26,705	$	31,116	$	37,356	$	27,339

(1) The average balance includes the rights or obligations to cash collateral, which are included in the fair value of derivative assets or derivative liabilities on the Statements of Condition at period end.

We continued to maintain an ample amount of asset liquidity. Liquidity investment levels can vary significantly based on liquidity needs, the availability of acceptable net spreads, the number of eligible counterparties that meet our unsecured credit risk criteria, and changes in the amount of Mission Assets. It is normal for liquidity investments to vary by up to several billion dollars on a daily basis. We conservatively carried a larger amount of liquidity investments leading up to year-end 2015 in order to ensure an adequate amount of available liquidity for our membership. In the first three months of 2016, we reduced liquidity investments, ending the quarter at $11.3 billion in outstanding balances.

Our overarching strategy for mortgage-backed securities is to keep holdings as close as possible to the regulatory maximum of three times regulatory capital, subject to the availability of securities that we believe provide acceptable risk/return tradeoffs. The balance of mortgage-backed securities at March 31, 2016 represented a 3.02 multiple of regulatory capital which exceeded the current regulatory limit due to a stock repurchase that occurred during the quarter. New purchases will be postponed until the existing ratio falls below the regulatory limit. The balance at March 31, 2016 consisted of $11.6 billion of securities issued by Fannie Mae or Freddie Mac (of which $2.4 billion were floating-rate securities), $0.9 billion of floating-rate securities issued by the National Credit Union Administration (NCUA), and $2.9 billion of securities issued by Ginnie Mae (which are primarily fixed rate). We held no private-label mortgage-backed securities.

The table below shows principal purchases and paydowns of our mortgage-backed securities for the first three months of 2016.

(In millions)	Mortgage-backed Securities Principal
Balance at December 31, 2015	$	15,203
Principal purchases	716
Principal paydowns	(592		)
Balance at March 31, 2016	$	15,327

Principal paydowns in the first three months of 2016 equated to a 15 percent annual constant prepayment rate, down slightly from a 16 percent rate in 2015.

(1) Includes unamortized premiums/discounts, fair value option valuation adjustments, hedging and other basis adjustments.

(2) The 11 FHLBanks have joint and several liability for the par amount of all of the Consolidated Obligations issued on their behalves. The par amount of the outstanding Consolidated Obligations for all of the FHLBanks was (in millions) $896,827 and $905,202 at March 31, 2016 and December 31, 2015, respectively.

Our preferred sources of funding for LIBOR-indexed assets are Discount Notes, adjustable-rate Bonds, and swapped fixed-rate Bonds because they give us the ability to effectively match the LIBOR reset periods embedded in these assets. Balances of Discount Notes fell in the first three months of 2016 compared to year-end primarily due to reductions in short-term (REPO) Advance borrowings along with a lower balance of liquidity investments as discussed above.

During the quarter, we also shifted the composition of shorter-term funding towards adjustable-rate and swapped fixed-rate Bonds in order to diversify our funding composition. This change in funding composition also decreases the basis risk to changes in spreads between cash flows received on LIBOR-indexed assets and interest paid on Discount Notes.

The composition of unswapped fixed-rate Bonds, which typically have initial maturities greater than one year, was relatively stable in the first three months of 2016 compared to 2015.

Deposits

Total deposits with us are normally a relatively minor source of low-cost funding. Total interest bearing deposits at March 31, 2016 were $0.7 billion, a decrease of 17 percent from year-end 2015. The average balance of total interest bearing deposits in the first three months of 2016 was $0.9 billion, similar to the average balance during the same period of 2015.

Derivatives Hedging Activity and Liquidity

Our use of and accounting for derivatives is discussed in the "Effect of the Use of Derivatives on Net Interest Income" section in "Results of Operations." Liquidity is discussed in the "Liquidity Risk" section in “Quantitative and Qualitative Disclosures About Risk Management.”

Capital Resources

The following tables present capital amounts and capital-to-assets ratios, on both a GAAP and regulatory basis.

	Three Months Ended				Year Ended
(In millions)	March 31, 2016				December 31, 2015
	Period End		Average		Period End		Average
GAAP and Regulatory Capital
GAAP Capital Stock	$	4,210	$	4,271	$	4,429	$	4,344
Mandatorily Redeemable Capital Stock	103		106		38		61
Regulatory Capital Stock	4,313		4,377		4,467		4,405
Retained Earnings	770		814		765		745
Regulatory Capital	$	5,083	$	5,191	$	5,232	$	5,150

	Three Months Ended				Year Ended
	March 31, 2016				December 31, 2015
	Period End		Average		Period End		Average
GAAP and Regulatory Capital-to-Assets Ratio
GAAP	4.78	%	4.52	%	4.36	%	4.81	%
Regulatory	4.89		4.63		4.40		4.88

Both GAAP and regulatory capital-to-assets ratios remained above the regulatory required minimum of four percent. We consider the regulatory ratio to be a better representation of financial leverage than the GAAP ratio because, although the GAAP ratio treats mandatorily redeemable capital stock as a liability, it protects investors in our debt in the same manner as GAAP capital stock and retained earnings.

A portion of capital stock is excess, meaning it is not required as a condition to being a member and not required to capitalize Mission Asset Activity. Excess capital stock provides a base of capital to manage financial leverage at prudent levels, augments loss protections for bondholders, and capitalizes a portion of growth in Mission Assets. The amount of excess capital stock, as defined by our Capital Plan, was $564 million at March 31, 2016, an increase of $103 million from year-end 2015.

Membership and Stockholders

In the first three months of 2016, we added three new member stockholders and lost three members, ending the quarter at 699. Two of the members lost merged with other Fifth District members and, therefore, the impact on our earnings and Mission Asset Activity was small.

The Finance Agency issued a final rule on FHLBank membership in January 2016. This rule imposes new membership requirements and eliminates all currently eligible captive insurance companies from FHLBank membership. The ruling also requires that these entities, which represented 15 members totaling $6.6 billion in Advances at December 31, 2015, pay off existing Advances by February 2017 and cease any new borrowings. Remaining Advances to these members totaled $1.5 billion at the end of the first quarter. The subsequent loss of this membership segment will not significantly affect our financial condition or results of operations.

RESULTS OF OPERATIONS

Components of Earnings and Return on Equity

The following table is a summary income statement for the three months endedMarch 31, 2016 and 2015. Each ROE percentage is computed by dividing income or expense for the category by the average amount of stockholders' equity for the period.

	Three Months Ended March 31,
(Dollars in millions)	2016					2015
	Amount			ROE (1)		Amount			ROE (1)
Net interest income	$	80		6.33	%	$	78		6.31	%
Non-interest (loss) income:

Assessments	6			0.44		7			0.56
Net income	$	48		3.83	%	$	61		4.97	%

(1) The ROE amounts have been computed using dollars in thousands. Accordingly, recalculations based upon the disclosed amounts (millions) in this table may produce nominally different results.

Profitability remained competitive in the first three months of 2016 as ROE continued to significantly exceed our benchmarks relative to short-term interest rates. Details on the individual factors contributing to the level and changes in profitability are explained in the sections below.

Net Interest Income

Components of Net Interest Income

The following table shows the major components of net interest income. Reasons for the variance in net interest income between the periods are discussed below.

	Three Months Ended March 31,
(Dollars in millions)	2016					2015
	Amount			% of Earning Assets		Amount			% of Earning Assets
Components of net interest rate spread:
Net (amortization)/accretion (1) (2)	$	(18	)	(0.07	)%	$	(7	)	(0.03	)%
Prepayment fees on Advances, net (2)	2			0.01		1			—
Other components of net interest rate spread	85			0.31		76			0.30
Total net interest rate spread	69			0.25		70			0.27
Earnings from funding assets with interest-free capital	11			0.04		8			0.04
Total net interest income/net interest margin (3)	$	80		0.29	%	$	78		0.31	%

(1) Includes (amortization)/accretion of premiums/discounts on mortgage assets and Consolidated Obligations and deferred transaction costs (concession fees) for Consolidated Obligations.

(2) These components of net interest rate spread have been segregated to display their relative impact.

(3) Net interest margin is net interest income as a percentage of average total interest earning assets.

50

Net Amortization/Accretion: Net amortization/accretion (generally referred to as "amortization") includes monthly recognition of premiums and discounts paid on purchases of mortgage assets, as well as premiums, discounts and concessions paid on Consolidated Obligations. Periodic amortization adjustments do not necessarily indicate a trend in economic return over the entire life of mortgage assets, although it is one component of lifetime economic returns.

Amortization increased in the first three months of 2016 compared to the same period in 2015 because net purchase premium balances grew by approximately 40 percent, primarily due to purchases of mortgage-backed securities, and average long-term mortgage rates fell during the first quarter of 2016.

Prepayment Fees on Advances: Fees for members' early repayment of certain Advances are designed to make us economically indifferent to whether members hold Advances to maturity or repay them before maturity. Although Advance prepayment fees can be and have been significant in the past, they were modest in the three months endedMarch 31, 2016 and 2015, reflecting a low amount of member prepayments of Advances.

Other Components of Net Interest Rate Spread: Excluding net amortization and prepayment fees, the total other components of net interest rate spread increased$9 million in the first three months of 2016 compared to the same period in 2015. The following factors, presented in approximate order of impact from largest to smallest, accounted for the changes in other components of net interest rate spread.

▪ LIBOR Asset funding-Favorable: Net interest income increased by an estimated $5 million due to lower rates on Discount Notes relative to LIBOR and because we held a larger portion of lower-cost Discount Notes relative to adjustable-rate LIBOR Bonds during this period to fund and hedge our LIBOR-indexed assets.

▪ MPP growth-Favorable: The average balance of mortgage loans held for portfolio increased $1.0 billion, which increased net interest income by an estimated $4 million.

▪ Fixed-rate asset funding-Unfavorable: A reduction in the amount of short-term debt that we used to fund longer-term fixed-rate mortgages lowered net interest income by an estimated $3 million.

▪ Higher spreads on mortgage-backed securities-Favorable: Higher spreads earned on recently purchased mortgage-backed securities increased net interest income by an estimated $3 million.

▪ Lower MPP spread-Unfavorable: The continued paydown of higher-yielding mortgage assets led to a decline in the spread earned on mortgage loans, decreasing net interest income by an estimated $3 million.

▪ Advance growth-Favorable: The $3.6 billion growth in average Advance balances improved net interest income by an estimated $2 million.

▪ Higher balances of mortgage-backed securities-Favorable: The average balance of the mortgage-backed securities portfolio rose $0.6 billion, which increased net interest income by an estimated $1 million.

Earnings from Capital: The earnings from funding assets with interest-free capital increased $3 million in the first three months of 2016 compared to the same period in 2015 due to modestly higher short-term interest rates following the Federal Reserve's decision to raise rates in December 2015.

Average Balance Sheet and Rates

The following table provides average balances and rates for major balance sheet accounts, which determine the changes in the net interest rate spread. All data include the impact of interest rate swaps, which we allocate to each asset and liability category according to their designated hedging relationship. The changes in the net interest rate spread and net interest margin between the two periods occurred mostly from the net impact of the factors discussed above in “Components of Net Interest Income.”

(Dollars in millions)	Three Months Ended						Three Months Ended

(1) Amounts used to calculate average rates are based on dollars in thousands. Accordingly, recalculations based upon the disclosed amounts (millions) may not produce the same results.

(2) Non-accrual loans are included in average balances used to determine average rate.

(3) Includes certificates of deposit and bank notes that are classified as available-for-sale securities.

(4) Includes available-for-sale securities based on their amortized costs. The yield information does not give effect to changes in fair value that are reflected as a component of stockholders' equity for available-for-sale securities.

(5) The average balance amounts include the rights or obligations to cash collateral, which are included in the fair value of derivative assets or derivative liabilities on the Statements of Condition at period end.

(6) Net interest margin is net interest income as a percentage of average total interest earning assets.

Rates on shorter-term interest-earning assets rose because average short-term interest rates were higher in the first three months of 2016 compared to the same period in 2015 following the increase in the Federal funds target rate in December 2015.

52

However, long-term rates fell period-over-period causing a modest decline in rates earned on longer-term assets resulting in a net average rate increase in total interest-earning assets of only 0.16 percentage points.

The increase in average rates on total interest-bearing liabilities was driven by higher rates on shorter-term liabilities that reset similar to short-term assets.

The net interest spread and net interest margin decreased primarily from the higher recognition of mortgage premium amortization, which was only partially offset by the increase in other components of net interest rate spread discussed in the previous section.

Volume/Rate Analysis

Changes in both average balances (volume) and interest rates influence changes in net interest income. The following table summarizes these changes and trends in interest income and interest expense.

(In millions)	Three Months Ended March 31, 2016 over 2015
	Volume (1)(3)			Rate (2)(3)			Total

(1) Volume changes are calculated as the change in volume multiplied by the prior year rate.

(2) Rate changes are calculated as the change in rate multiplied by the prior year average balance.

(3) Changes that are not identifiable as either volume-related or rate-related, but rather are 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.

Effect of the Use of Derivatives on Net Interest Income

The following table shows the effect of using derivatives on net interest income. The effect on earnings from the non-interest components of derivatives related to market value adjustments is provided in “Non-Interest Income and Non-Interest Expense.”

(In millions)	Three Months Ended March 31,
	2016			2015
Advances:
Amortization of hedging activities in net interest income	$	(1	)	$	(1	)
Net interest settlements included in net interest income	(17		)	(21		)
Mortgage loans:
Amortization of derivative fair value adjustments in net interest income	(2		)	(1		)
Consolidated Obligation Bonds:
Net interest settlements included in net interest income	3			5
Decrease to net interest income	$	(17	)	$	(18	)

Most of our use of derivatives synthetically convert the intermediate- and long-term fixed interest rates on certain Advances and Bonds to adjustable-coupon rates tied to short-term LIBOR (mostly one- and three-month repricing resets). These adjustable-rate coupons normally carry lower interest rates than the fixed rates. The use of derivatives lowered net interest income in each period primarily because the Advances that were swapped to short-term LIBOR had higher fixed interest rates than the Bonds that were swapped to short-term LIBOR. We accepted this reduction in earnings because it enabled us, by design, to significantly lower market risk exposure by creating a much closer match of actual cash flows between assets and liabilities than would occur otherwise. The reduction in earnings was similar in the first three months of both 2016 and 2015.

Non-Interest Income and Non-Interest Expense

The following table presents non-interest income and non-interest expense for each of the three months endedMarch 31, 2016 and 2015.

	Three Months Ended March 31,

Total non-interest expense to average regulatory capital (1)	1.69			1.42

(1) Amounts used to calculate percentages are based on dollars in thousands. Accordingly, recalculations based upon the disclosed amounts (millions) may not produce the same results.

Non-interest income decreased in the first three months of 2016 compared to the same period of 2015 primarily due to unrealized losses from changes in market values on certain Consolidated Obligations held at fair value, net of derivatives used

54

to hedge the Obligations, as presented in the table below. The change in other non-interest expense in the first three months of 2016 resulted from an increase in issuance costs (concession fees) on Consolidated Obligations held at fair value, which are immediately recognized into non-interest expense.

The total amount of income volatility in derivatives and hedging activities was moderate compared to the notional principal amounts and consistent with the close hedging relationships of our derivative transactions.

Segment Information

Note 17 of the Notes to Unaudited Financial Statements presents information on our two operating business segments. We manage financial operations and market risk exposure primarily at the macro level, and within the context of the entire balance sheet, rather than exclusively at the level of individual segments. Under this approach, the market risk/return profile of each segment may not match, or possibly even have the same trends as, what would occur if we managed each segment on a stand-alone basis. The table below summarizes each segment's operating results for the periods shown.

(1) Amounts used to calculate returns are based on numbers in thousands. Accordingly, recalculations based upon the disclosed amounts (millions) may not produce the same results.

Traditional Member Finance Segment

The decrease in net income in the first three months of 2016, compared to the same period of 2015, was due primarily to the unrealized losses from changes in market values on certain Consolidated Obligations held at fair value, as explained above. This factor was partially offset by higher spreads earned on Advances and mortgage-backed securities. The higher spreads earned on Advances were primarily due to lower rates on Discount Notes relative to LIBOR and because we held a larger portion of lower-cost Discount Notes compared to adjustable-rate Bonds to fund and hedge LIBOR-indexed Advances.

MPP Segment

The MPP continued to earn a substantial level of profitability compared to market interest rates, with a moderate amount of market risk and small amount of credit risk. In the first three months of 2016, the MPP averaged seven percent of total average assets while accounting for 16 percent of earnings. Net income and ROE declined in the first three months of 2016 compared to the same period in 2015 due to the increased amortization of purchased mortgage premiums recognized during the quarter as a result of lower average mortgage rates and the continued paydown of higher-yielding mortgage assets. These unfavorable factors were partially offset by growth in MPP balances.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT RISK MANAGEMENT

Market Risk

Market Value of Equity and Duration of Equity - Entire Balance Sheet

Two key measures of long-term market risk exposure are the sensitivities of the market value of equity and the duration of equity to changes in interest rates and other variables, as presented in the following tables for various instantaneous and permanent interest rate shocks (in basis points). We compiled average results using data for each month end. Given the current very low level of rates, the down rate shocks are nonparallel scenarios, with short-term rates decreasing less than long-term rates such that no rate falls below zero.

December 31, 2015	(6.9	)	(5.7	)	(2.8	)	0.6		2.8	3.3	3.2

During the first three months of 2016, as in 2015, consistent with our historical practice and risk appetite, we positioned market risk exposure to changing interest rates at a moderate level.

At March 31, 2016, the duration of equity measured in the down 200 basis point interest rate shock exceeded our policy limit by 0.2 and the three-month end average exceeded the limit by 0.4. The primary reason for exceeding our policy limit is the distortion of this risk measure in shocked interest rate scenarios where the model assumes that all interest rates are not floored at zero. We do not expect to exceed this policy limit going forward as we enhanced our model to floor rates at zero consistent with our other market risk measures.

Based on the totality of our risk analysis, we expect that profitability, defined as the level of ROE compared with short-term market rates, will remain competitive unless interest rates change by extremely large amounts in a short period of time. Decreases in long-term interest rates even up to two percentage points (which would put fixed-rate mortgages below two percent) would still result in profitability being well above market interest rates. Similarly, we believe that profitability would

57

not become uncompetitive in a rising rate environment unless long-term rates were to permanently increase in a short period of time by five percentage points or more, combined with short-term rates increasing to at least seven percent.

Market Risk Exposure of the Mortgage Assets Portfolio

The mortgage assets portfolio normally accounts for almost all market risk exposure because of prepayment volatility that we cannot completely hedge while maintaining sufficient net spreads. Sensitivities of the market value of equity allocated to the mortgage assets portfolio under interest rate shocks (in basis points) are shown below. At March 31, 2016, the mortgage assets portfolio had an assumed capital allocation of $1.1 billion based on the entire balance sheet's regulatory capital-to-assets ratio. Average results are compiled using data for each month-end. The market value sensitivities are one measure we use to analyze the portfolio's estimated market risk exposure.

% Change in Market Value of Equity-Mortgage Assets Portfolio

Month-End Results
March 31, 2016	(37.8	)%	(35.5	)%	(18.3	)%	—	(4.7	)%	(19.2	)%	(35.7	)%
December 31, 2015	(41.7	)%	(30.8	)%	(6.4	)%	—	(9.6	)%	(24.4	)%	(40.7	)%

At March 31, 2016, the risk exposure of the mortgage assets portfolio to changing interest rates was similar to year-end 2015. The dollar amount of exposure for any individual rate shock can be obtained by multiplying the percentage change by the assumed equity allocation. We believe the mortgage assets portfolio continued to have an acceptable amount of market risk exposure relative to its actual and expected profitability and consistent with our risk appetite philosophy.

Capital Adequacy

Retained Earnings

We must hold sufficient capital to protect against exposure to various risks, including market, credit, and operational. We regularly conduct a variety of measurements and assessments for capital adequacy. Our current retained earnings policy sets forth a range of $375 million to $600 million as the amount of retained earnings we believe is necessary to mitigate impairment risk from market risk exposure and to provide for dividend stability from factors that could cause earnings to be volatile. At March 31, 2016, the $770 million of retained earnings was comprised of $551 million unrestricted (a decrease of $5 million from year-end 2015) and $219 million restricted (an increase of $10 million from year-end 2015), which by the FHLBank System's Joint Capital Enhancement Agreement we are not permitted to distribute as dividends.

Due to the regulatory environment and employing an abundance of caution, we will continue to carry a greater amount of retained earnings than required by the policy and will continue to bolster capital adequacy over time by allocating a portion of earnings to a separate restricted retained earnings account in accordance with the FHLBank System's Joint Capital Enhancement Agreement. We believe that the current amount of retained earnings is sufficient to mitigate members' impairment risk of their capital stock investment and to provide the opportunity to stabilize dividends when profitability may be volatile.

Market Capitalization Ratios

We measure two sets of market capitalization ratios. One measures the market value of equity (i.e., total capital) relative to the par value of regulatory capital stock (which is GAAP capital stock and mandatorily redeemable capital stock). The other measures the market value of total capital relative to the book value of total capital, which includes all components of capital. The measures provide a point-in-time indication of the FHLB's liquidation or franchise value and can also serve as a measure of realized or potential market risk exposure.

58

The following table presents the market value of equity to regulatory capital stock (excluding retained earnings) for several interest rate environments.

	March 31, 2016		December 31, 2015
Market Value of Equity to Par Value of Regulatory Capital Stock - Base Case (Flat Rates) Scenario	113	%	109	%
Market Value of Equity to Par Value of Regulatory Capital Stock - Down Shock (1)	110		109
Market Value of Equity to Par Value of Regulatory Capital Stock - Up Shock (2)	108		104

(1) Represents a down shock of 100 basis points.

(2) Represents an up shock of 200 basis points.

A base case value below par could indicate that, in the remote event of an immediate liquidation scenario involving redemption of all capital stock, capital stock may be returned to stockholders at a value below par. This could be due to experiencing risks that lower the market value of capital and/or to having an insufficient amount of retained earnings. In the first three months of 2016, the market capitalization ratios in the scenarios presented continued to be above the minimum policy limits. The ratios increased slightly at March 31, 2016 compared to the end of 2015, and remain acceptable because retained earnings were 18 percent of regulatory capital stock at March 31, 2016 and we maintained risk exposures at moderate levels.

The following table presents the market value of equity to the book value of total capital.

	March 31, 2016		December 31, 2015
Market Value of Equity to Book Value of Capital - Base Case (Flat Rates) Scenario (1)	96	%	94	%
Market Value of Equity to Book Value of Capital - Down Shock (1)(2)	93		93
Market Value of Equity to Book Value of Capital - Up Shock (1)(3)	92		89

(1) Capital includes total capital and mandatorily redeemable capital stock.

(2) Represents a down shock of 100 basis points.

(3) Represents an up shock of 200 basis points.

A base-case value below par indicates that we have realized or could realize risks (especially market risk) such that the market value of total capital owned by stockholders, which includes regulatory capital stock and retained earnings, is below par value (i.e., below 100 percent of the total book value). The base-case ratio of 96 percent at March 31, 2016 indicates that the market value of total capital is $209 million below the par value of total capital. In a scenario in which interest rates increase 200 basis points, the market value of total capital would be $446 million below the par value of total capital, which indicates that capital stock would still be redeemable at par but stockholders would not receive the full sum of their ownership claims in the FHLB which include both capital stock and retained earnings.

Credit Risk

Overview

Our business entails a significant amount of inherent credit risk exposure. We believe our risk management practices, discussed below, bring the amount of residual credit risk to a minimal level. We have no loan loss reserves or impairment recorded for Credit Services, investments, and derivatives and a minimal amount of legacy credit risk exposure to the MPP.

Credit Services

Overview: We have policies and practices to manage credit risk exposure from our secured lending activities, which include Advances and Letters of Credit. The objective of our credit risk management is to equalize risk exposure across members and counterparties to a zero level of expected losses, consistent with our conservative risk management principles and desire to have virtually no residual credit risk related to member borrowings.

Collateral: We require each member to provide us a security interest in eligible collateral before it can undertake any secured borrowing. Eligible collateral includes single-family loans, multi-family loans, home equity loans and lines of credit, commercial real estate, bond securities and farm real estate. The estimated value of pledged collateral is discounted in order to

59

offset market, credit and liquidity risks that may affect the collateral's realizable value if it must be liquidated. Over-collateralization by one member is not applied to another member. At March 31, 2016, our policy of over-collateralization resulted in total collateral pledged of $302.6 billion to serve total borrowing capacity of $257.6 billion. The collateral composition remained relatively stable compared to the end of 2015.

Borrowing Capacity/Lendable Value: We determine borrowing capacity against pledged collateral by establishing minimum levels of over-collateralization (Collateralized Maintenance Requirements or CMRs). CMRs result in a lendable value, or borrowing capacity, that is less than the amount of pledged collateral.

CMRs are determined by statistical analysis and management assumptions relating to historical price volatility, inherent credit risks, liquidation timing and costs, and the current credit and economic environment. We apply CMR results to the estimated values of pledged assets. CMRs vary among pledged assets and members based on the financial strength of the member institution, the level of collateral status, the issuer of bond collateral or the quality of securitized assets, the marketability of the pledged assets, the payment performance of pledged loan collateral, and the quality of loan collateral as reflected in the manner in which it was underwritten and is administered. The range of lendable values applied to each major collateral type did not change in the first three months of 2016.

Internal Credit Ratings: We perform credit underwriting of our members and nonmember borrowers and assign them an internal credit rating. The credit ratings are based on internal credit analysis and consideration of available credit ratings from independent credit rating organizations. The credit ratings are used in conjunction with other measures of the credit risk and pledged collateral, as described above, in managing credit risk exposure to member and nonmember borrowers.

Member Failures, Closures, and Receiverships: There was one member failure in 2016 through the date of this filing. We had no outstanding exposure to this institution.

MPP

Overview: We believe that the residual amount of credit risk exposure to loans in the MPP is minimal, based on the same factors described in the 2015 Annual Report on Form 10-K. We believe, based on our analysis, that future credit losses will not harm capital adequacy and will not significantly affect profitability except under the most extreme and unlikely credit conditions.

Conventional Loan Portfolio Characteristics:The levels of loan-to-value ratios have improved over the last several years, consistent with the portfolio's excellent credit quality. The positive trends reflect the sustained recovery and improvement in the overall housing market. At March 31, 2016, the weighted average loan-to-value ratios for conventional loans based on origination values and estimated current values were 72 percent and 62 percent, respectively. These ratios were similar at December 31, 2015.

Credit Performance: The table below provides an analysis of conventional loans delinquent or in the process of foreclosure, along with the national average serious delinquency rate.

	Conventional Loan Delinquencies
(Dollars in millions)	March 31, 2016			December 31, 2015
Early stage delinquencies - unpaid principal balance (1)	$	46		$	51
Serious delinquencies - unpaid principal balance (2)	$	31		$	32
Early stage delinquency rate (3)	0.6		%	0.7		%
Serious delinquency rate (4)	0.4		%	0.4		%
National average serious delinquency rate (5)	1.7		%	1.8		%

(1) Includes conventional loans 30 to 89 days delinquent and not in foreclosure.

(2) Includes conventional loans that are 90 days or more past due or where the decision of foreclosure or a similar alternative such as pursuit of deed-in-lieu has been reported.

(3) Early stage delinquencies expressed as a percentage of the total conventional loan portfolio.

(4) Serious delinquencies expressed as a percentage of the total conventional loan portfolio.

(5) National average number of fixed-rate prime conventional loans that are 90 days or more past due or in the process of foreclosure is based on the most recent national delinquency data available. The March 31, 2016 rate is based on December 31, 2015 data.

60

The MPP has experienced a very small amount of delinquencies and foreclosures, with rates continuing to be well below national averages. This further supports our view that the overall portfolio is comprised of high-quality, well-performing loans.

Credit Enhancements: Conventional mortgage loans are supported against credit losses by various combinations of primary mortgage insurance (PMI), supplemental mortgage insurance (SMI) (for loans purchased before February 2011), and the Lender Risk Account (LRA). The LRA is a holdback of a portion of the initial purchase price to cover expected credit losses for a specific pool of loans. Starting after five years from the loan purchase date, we may return the holdback to Participating Financial Institutions (PFIs) if they manage credit risk to predefined acceptable levels of exposure on the loan pools they sell to us. The LRA had balances of $164 million and $158 million at March 31, 2016 and December 31, 2015, respectively. For more information, see Note 9 of the Notes to Unaudited Financial Statements.

Credit Losses: The following table shows the effects of credit enhancements on our estimation of credit losses at the noted periods. Estimated incurred credit losses, after credit enhancements, are accounted for in the allowance for credit losses or as a charge off (i.e., a reduction to the principal of mortgage loans held for portfolio).

(In millions)	March 31, 2016			December 31, 2015
Estimated incurred credit losses, before credit enhancements	$	(12	)	$	(14	)
Estimated amounts deemed recoverable by:
Primary mortgage insurance	1			1
Supplemental mortgage insurance	7			8
Lender Risk Account	2			2
Estimated incurred credit losses, after credit enhancements	$	(2	)	$	(3	)

The small amount of incurred losses provides further support on the aggregate health of the portfolio. Credit risk exposure depends on the actual and potential credit performance of the loans in each pool compared to the pool's equity (on individual loans) and credit enhancements, including PMI, the LRA, and SMI.

In addition to the allowance for credit losses recorded, we regularly analyze potential ranges of additional lifetime credit risk exposure for the loans in the MPP. Even under adverse scenarios for either home prices or unemployment rates, we expect that further credit losses would not significantly decrease profitability.

Investments

Liquidity Investments: Liquidity investments may be unsecured, guaranteed by the U.S. government, or secured (i.e., collateralized). For unsecured liquidity investments, we invest in the debt securities of highly rated, investment-grade institutions, have appropriate and conservative limits on dollar and maturity exposure to each institution, and have strong credit underwriting practices, including active monitoring of credit quality of our counterparties and of the environment in which they operate. We purchased liquidity investments from counterparties that have a strong ability to repay principal and interest.

Finance Agency regulations limit our unsecured liquidity investments to a counterparty or group of affiliated counterparties to maturities of no more than nine months and a dollar amount based on a percentage of eligible regulatory capital. The permissible percentage ranges from one percent to 15 percent of regulatory capital based on the counterparty's lowest long-term credit rating of its debt from a nationally recognized statistical rating organization (NRSRO). The lowest long-term credit rating for a counterparty to which we are permitted to extend credit is double-B. We complement reliance on NRSRO ratings for unsecured investment activity by also considering internal credit risk analytics on unsecured counterparties.

During the first three months of 2016, we purchased a portion of our total liquidity investments from counterparties for which the investments are secured with collateral (secured resale agreements). We believe these investments present little or no credit risk exposure to us.

At March 31, 2016, all of the $7.1 billion of unsecured investment exposure was to counterparties with holding companies domiciled in countries receiving either AAA or AA long-term sovereign ratings. Furthermore, we restrict a significant portion of unsecured lending to overnight maturities, which further limits risk exposure to these counterparties. By Finance Agency regulation, all counterparties exposed to non-U.S. countries are required to be domestic U.S. branches of foreign counterparties. We also limit exposure to counterparties and countries that could have significant direct or indirect exposure to European sovereign debt.

63

Mortgage-Backed Securities.

GSE Mortgage-Backed Securities

At March 31, 2016, $11.6 billion of mortgage-backed securities held were GSE securities issued by Fannie Mae and Freddie Mac, which provide credit safeguards by guaranteeing either timely or ultimate payments of principal and interest. We believe that the conservatorships of Fannie Mae and Freddie Mac lower the chance that they would not be able to fulfill their credit guarantees and that the securities issued by these two GSEs are effectively government guaranteed. In addition, based on the data available to us and our purchase practices, we believe that most of the mortgage loans backing our GSE mortgage-backed securities are of high quality with acceptable credit performance.

Mortgage-Backed Securities Issued by Other Government Agencies

We also invest in mortgage-backed securities issued and guaranteed by Ginnie Mae and the NCUA. These investments totaled $3.8 billion at March 31, 2016. We believe that the strength of the issuers' guarantees and backing by the full faith and credit of the U.S. government is sufficient to protect us against credit losses on these securities.

Derivatives

Credit Risk Exposure: We mitigate most of the credit risk exposure resulting from derivative transactions through collateralization. The table below presents the derivative positions to which we had credit risk exposure at March 31, 2016.

(In millions)
Credit Rating (1)	Total Notional		Net Derivatives Fair Value Before Collateral			Cash Collateral Pledged To (From) Counterparty			Net Credit Exposure to Counterparties

(1) Each category includes the related plus (+) and minus (-) ratings (i.e., “A” includes “A+” and “A-” ratings).

(2) Represents derivative transactions cleared with clearinghouses, which are not rated.

(3) Represents Mandatory Delivery Contracts.

Based on both the gross and net exposures, we had a minimal amount of residual credit risk exposure on uncleared derivatives throughout the first three months of 2016. Gross exposure would likely increase if interest rates rise and could increase if the composition of our derivatives change. However, contractual collateral provisions in these derivatives would limit net exposure to acceptable levels.

Although we cannot predict if we will realize credit risk losses from any of our derivatives counterparties, we believe that all of the counterparties will be able to continue making timely interest payments and, more generally, to continue to satisfy the terms and conditions of their derivative contracts with us. As of March 31, 2016, we had $0.3 billion of notional principal of interest rate swaps outstanding to one member, JPMorgan Chase Bank, N.A., which also had outstanding credit services with us. Due to the amount of market value collateralization, we had no outstanding credit exposure to this counterparty related to interest rate swaps outstanding.

64

Lehman Brothers Derivatives: See Note 19 of the Notes to Unaudited Financial Statements for information on derivatives we had with Lehman Brothers at the time of its bankruptcy in September 2008.

Exposure to Member Concentration

We regularly assess concentration risks from business activity. We believe that the current concentration of Advance activity is consistent with our risk management philosophy, and the impact of borrower concentration on market risk, credit risk, and operational risk, after considering mitigating controls, is small.

Liquidity Risk

Liquidity Overview

The FHLBank System's primary source of funds is the sale of Consolidated Obligations in the capital markets. Our ability to obtain funds through the sale of Consolidated Obligations depends on the financial market's perceived riskiness of the Obligations and on prevailing conditions in the capital markets, particularly the short-term capital markets. The System has a large reliance on short-term funding; therefore the System has a sharp focus on managing liquidity risk to low levels. As shown on the Statements of Cash Flows, in the first three months of 2016, our portion of the System's debt issuances totaled $90.9 billion for Discount Notes and $14.9 billion for Bonds. The System's favorable debt ratings, the implicit U.S. government backing of our debt, and our effective risk management have been instrumental in ensuring satisfactory access to the capital markets.

We believe our liquidity position, as well as that of the System, remained strong during the first three months of 2016. Our overall ability to fund our operations through debt issuances at acceptable interest costs remained sufficient. Investor demand of System debt remains robust and, we believe, increased in the first quarter of 2016. Although we can make no assurances, we expect this to continue to be the case. We believe the possibility of a liquidity or funding crisis in the System that would impair our ability to participate, on a cost-effective basis, in issuances of new debt, service outstanding debt, maintain adequate capitalization, or pay competitive dividends is remote.

We must meet both operational and contingency liquidity requirements. We satisfied the operational liquidity requirement by both meeting a contingency liquidity requirement, discussed below, and because we were able to adequately access the capital markets to issue debt. Liquidity investments, most of which were overnight, were generally in the range of $10 billion to $15 billion during the first three months of 2016. In addition, Finance Agency guidance requires us to target at least 5 to 15 consecutive days of positive liquidity based on specific assumptions under two scenarios. We target holding at least three extra days of positive liquidity under each scenario, although as market conditions warrant we may hold, and often do hold, additional amounts.

Contingency Liquidity Requirement

Contingency liquidity risk is the potential inability to meet liquidity needs because our access to the capital markets to issue Consolidated Obligations is restricted or suspended for a period of time due to a market disruption, operational failure, or real or perceived credit quality problems. We continued to hold an ample amount of liquidity reserves to protect against contingency liquidity risk.

(2) Includes net liabilities maturing in the next seven business days, assets traded not yet settled, Advance commitments outstanding, Advances maturing in the next seven business days, and a three percent hypothetical increase in Advances.

65

Deposit Reserve Requirement

To support our member deposits, we also must meet a statutory deposit reserve requirement. The sum of our investments in obligations of the United States, deposits in eligible banks or trust companies, and Advances with a final maturity not exceeding five years must equal or exceed the current amount of member deposits. The following table presents the components of this liquidity requirement.

Contractual Obligations

The following table summarizes our contractual obligations at March 31, 2016. The allocations according to the expiration terms and payment due dates of these obligations were not materially different from those at the end of 2015. Changes reflected normal business variations. We believe that, as in the past, we will continue to have sufficient liquidity, including from access to the debt markets to issue Consolidated Obligations, to satisfy these obligations on a timely basis.

Item 4. Controls and Procedures.

DISCLOSURE CONTROLS AND PROCEDURES

As of March 31, 2016, the FHLB's management, including its principal executive officer and principal financial officer, evaluated the effectiveness of our disclosure controls and procedures as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934 (the “Exchange Act”). Based upon that evaluation, these two officers each concluded that, as of March 31, 2016, the FHLB maintained effective disclosure controls and procedures designed to ensure that information required to be disclosed in the reports that it files under the Exchange Act is (1) accumulated and communicated to management as appropriate to allow timely decisions regarding disclosure and (2) recorded, processed, summarized and reported within the time periods specified in the rules and forms of the Securities and Exchange Commission.

As of March 31, 2016, the FHLB's management, including its principal executive officer and principal financial officer, evaluated the FHLB's internal control over financial reporting. Based upon that evaluation, these two officers each concluded that there were no changes in the FHLB's internal control over financial reporting that occurred during the quarter ended March 31, 2016 that materially affected, or are reasonably likely to materially affect, the FHLB's internal control over financial reporting.

Summary of Significant Accounting Policies

Mar. 31, 2016

Accounting Policies [Abstract]

Basis of Accounting [Text Block]

Basis of Presentation

The accompanying interim financial statements of the FHLB have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP). The preparation of financial statements in accordance with GAAP requires management to make assumptions and estimates. These assumptions and estimates affect the reported amount of assets and liabilities, the disclosure of contingent assets and liabilities, and the reported amounts of income and expenses. Actual results could differ from these estimates. The interim financial statements presented are unaudited, but they include all adjustments (consisting of only normal recurring adjustments) which are, in the opinion of management, necessary for a fair statement of the financial condition, results of operations, and cash flows for such periods. These financial statements do not include all disclosures associated with annual financial statements and accordingly should be read in conjunction with the audited financial statements and notes included in the FHLB's Annual Report on Form 10-K for the year ended December 31, 2015 filed with the Securities and Exchange Commission (SEC). Results for the three months endedMarch 31, 2016 are not necessarily indicative of operating results for the full year.

The FHLB presents certain financial instruments, including derivative instruments and securities purchased under agreements to resell, on a net basis when it has a legal right of offset and all other requirements for netting are met (collectively referred to as the netting requirements). For these instruments, the FHLB has elected to offset its asset and liability positions, as well as cash collateral received or pledged, when it has met the netting requirements. The FHLB did not have any offsetting liabilities related to its securities purchased under agreements to resell for the periods presented.

The net exposure for these financial instruments can change on a daily basis; therefore, there may be a delay between the time this exposure change is identified and additional collateral is requested, and the time this collateral is received or pledged. Likewise, there may be a delay for excess collateral to be returned. For derivative instruments that meet the requirements for netting, any excess cash collateral received or pledged is recognized as a derivative liability or derivative asset. Additional information regarding these agreements is provided in Note 10. Based on the fair value of the related collateral held, the securities purchased under agreements to resell were fully collateralized for the periods presented. For more information about the FHLB's investments in securities purchased under agreements to resell, see “Item 8. Financial Statements and Supplementary Data - Note 1 - Summary of Significant Accounting Policies” in the FHLB's 2015 Annual Report on Form 10-K.

The FHLB has evaluated subsequent events for potential recognition or disclosure through the issuance of these financial statements and believes there have been no material subsequent events requiring additional disclosure or recognition in these financial statements.

Contingent Put and Call Options in Debt Instruments.On March 14, 2016, the Financial Accounting Standards Board (FASB) issued amendments to clarify the requirements for assessing whether contingent call (put) options that can accelerate the payment of principal on debt instruments are clearly and closely related to their debt hosts. The guidance requires entities to apply only the four-step decision sequence when assessing whether the economic characteristics and risks of call (put) options are clearly and closely related to the economic characteristics and risks of their debt hosts. Consequently, when a call (put) option is contingently exercisable, an entity does not have to assess whether the event that triggers the ability to exercise a call (put) option is related to interest rates or credit risks. This guidance becomes effective for the FHLB for the interim and annual periods beginning after December 15, 2016, and early adoption is permitted. The guidance should be applied on a modified retrospective basis to existing debt instruments as of the beginning of the period for which the amendments are effective. The FHLB is in the process of evaluating this guidance, and its effect on the FHLB's financial condition, results of operations, and cash flows has not yet been determined.

Effect of Derivative Contract Novations on Existing Hedge Accounting Relationships.On March 10, 2016, the FASB issued amendments to clarify that a change in the counterparty to a derivative instrument that has been designated as the hedging instrument under GAAP does not, in and of itself, require dedesignation of that hedging relationship provided that all other hedge accounting criteria continue to be met. This guidance becomes effective for the FHLB for the interim and annual periods beginning after December 15, 2016, and early adoption is permitted. The amendments provide entities with the option to apply the guidance using either a prospective approach or a modified retrospective approach, retrospectively applied to all derivative instruments that meet the specific conditions. The FHLB elected to early adopt the guidance prospectively on January 1, 2016. The adoption of this guidance had no effect on the FHLB's financial condition, results of operations, and cash flows.

Leases. On February 25, 2016, the FASB issued guidance which requires recognition of lease assets and lease liabilities on the Statement of Condition and disclosure of key information about leasing arrangements. In particular, this guidance requires a lessee, of operating or finance leases, to recognize on the Statement of Condition a liability to make lease payments and a right-of-use asset representing its right to use the underlying asset for the lease term. However, for leases with a term of 12 month or less, a lessee is permitted to make an accounting policy election not to recognize lease assets and lease liabilities.The guidance becomes effective for the FHLB for the interim and annual periods beginning after December 15, 2018, and early application is permitted. The guidance requires lessors and lessees to recognize and measure leases at the beginning of the earliest period presented in the financial statements using a modified retrospective approach. The FHLB is in the process of evaluating this guidance, and its effect on the FHLB's financial condition, results of operations, and cash flows has not yet been determined.

Recognition and Measurement of Financial Assets and Financial Liabilities. On January 5, 2016, the FASB issued amended guidance on certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. This guidance includes, but is not limited to, the following:

▪ Requires equity investments (with certain exceptions) to be measured at fair value with changes in fair value recognized in net income.

▪ Require an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected the fair value option.

▪ Requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset on the balance sheet or the accompanying notes to the financial statements.

▪ Eliminates the requirement for public entities to disclose the method(s) and significant assumptions used to estimate the fair value for financial instruments measured at amortized cost on the balance sheet.

The guidance becomes effective for the FHLB for the interim and annual periods beginning after December 15, 2017, and early adoption is only permitted for certain provision. The amendments, in general, should be applied by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the period of adoption. The FHLB is in the process of evaluating this guidance and its effect on the FHLB's financial condition, results of operations, and cash flows.

Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement. On April 15, 2015, the FASB issued amendments to clarify the accounting for cloud computing arrangements. The amendments provide guidance to customers on determining whether a cloud computing arrangement includes a software license. If the arrangement includes a software license, then the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If the arrangement does not contain a software license, the customer should account for the arrangement as a service contract. This guidance became effective for the FHLB for the interim and annual periods beginning on January 1, 2016, and was adopted prospectively. The adoption of this guidance had no material effect on the FHLB's financial condition, results of operations, and cash flows.

Simplifying the Presentation of Debt Issuance Costs. On April 7, 2015, the FASB issued guidance to simplify the presentation of debt issuance costs. This guidance requires that debt issuance costs related to a recognized debt liability be presented in the Statement of Condition as a direct deduction from the carrying amount of the liability, consistent with the presentation of debt discounts. This guidance became effective for the FHLB for the interim and annual periods beginning on January 1, 2016. As a result of adopting this guidance, unamortized concessions (in thousands) of $13,042 included in other assets at December 31, 2015 were reclassified as a reduction in the balance of the corresponding Consolidated Obligations. The reclassification resulted in a decrease (in thousands) of $13,042 in Consolidated Bonds at December 31, 2015. Accordingly, the FHLB's total assets and total liabilities each decreased by (in thousands) $13,042 at December 31, 2015. The adoption of this guidance had no effect on the FHLB's results of operations and cash flows.

Realized Gains and Losses. From time to time the FHLB may sell securities out of its held-to-maturity portfolio. These securities, generally, have less than 15 percent of the acquired principal outstanding at the time of the sale. These sales are considered maturities for the purposes of security classification. For the three months endedMarch 31, 2016 and 2015, the FHLB did not sell any held-to-maturity securities.

Other than Temporary Impairment Analysis [Text Block]

Other-Than-Temporary Impairment Analysis

The FHLB evaluates any of its individual available-for-sale and held-to-maturity investment securities holdings in an unrealized loss position for other-than-temporary impairment on a quarterly basis.

For its Other U.S. obligations and GSE investments (mortgage-backed securities and non-mortgage-backed securities), the FHLB has determined that the strength of the issuers' guarantees through direct obligations or support from the U.S. government is sufficient to protect the FHLB from losses based on current expectations. As a result, the FHLB determined that, as of March 31, 2016, all of the gross unrealized losses on these investments were temporary as the declines in market value of these securities were not attributable to credit quality. Furthermore, the FHLB does not intend to sell the investments, and it is not more likely than not that the FHLB will be required to sell the investments before recovery of their amortized cost bases. As a result, the FHLB did not consider any of these investments to be other-than-temporarily impaired at March 31, 2016.

The FHLB did not consider any of its investments to be other-than-temporarily impaired at December 31, 2015.

The FHLB offers certain fixed and variable-rate Advances to members that may be prepaid on specified dates (call dates) without incurring prepayment or termination fees (callable Advances). If the call option is exercised, replacement funding may be available. At March 31, 2016 and December 31, 2015, the FHLB had callable Advances (in thousands) of $14,731,435 and $14,095,712. Other Advances may only be prepaid subject to a prepayment fee paid to the FHLB that makes the FHLB financially indifferent to the prepayment of the Advance.

The FHLB also offers putable Advances. With a putable Advance, the FHLB effectively purchases put options from the member that allows the FHLB to terminate the Advance at predetermined dates. The FHLB normally would exercise its put option when interest rates increase relative to contractual rates. At March 31, 2016 and December 31, 2015, the FHLB had putable Advances, excluding those where the related put options have expired, totaling (in thousands) $1,033,900 and $1,046,400.

Allowance for Credit Losses

Allowance for Credit Losses [Abstract]

Allowance for Credit Losses [Text Block]

Allowance for Credit Losses

The FHLB has established an allowance methodology for each of the FHLB's portfolio segments: credit products (Advances, Letters of Credit and other extensions of credit to members); FHA mortgage loans held for portfolio; and conventional mortgage loans held for portfolio.

Credit products

The FHLB manages its credit exposure to credit products through an integrated approach that includes establishing a credit limit for each borrower, includes an ongoing review of each borrower's financial condition and is coupled with collateral and lending policies to limit risk of loss while balancing borrowers' needs for a reliable source of funding. In addition, the FHLB lends to eligible borrowers in accordance with federal statutes, including the FHLBank Act and Finance Agency regulations, which require the FHLB to obtain sufficient collateral to fully secure credit products. The estimated value of the collateral required to secure each member's credit products is calculated by applying collateral discounts, or haircuts, to the value of the collateral. The FHLB accepts certain investment securities, residential mortgage loans, deposits and other real estate related assets as collateral. In addition, community financial institutions are eligible to utilize expanded statutory collateral provisions for small business, agriculture loans and community development loans. The FHLB's capital stock owned by its member borrowers is also pledged as collateral. Collateral arrangements and a member’s borrowing capacity vary based on the financial condition and performance of the institution, the types of collateral pledged and the overall quality of those assets. The FHLB can also require additional or substitute collateral to protect its security interest. Management of the FHLB believes that these policies effectively manage the FHLB's credit risk from credit products.

Members experiencing financial difficulties are subject to FHLB-performed “stress tests” of the impact of poorly performing assets on the member’s capital and loss reserve positions. Depending on the results of these tests and the level of overcollateralization, a member may be allowed to maintain pledged loan assets in its custody, may be required to deliver those loans into the custody of the FHLB or its agent, and/or may be required to provide details on these loans to facilitate an estimate of their fair value. The FHLB perfects its security interest in all pledged collateral. The FHLBank Act affords any security interest granted to the FHLB by a member priority over the claims or rights of any other party except for claims or rights of a third party that would be entitled to priority under otherwise applicable law and that are held by a bona fide purchaser for value or by a secured party holding a prior perfected security interest.

Using a risk-based approach, the FHLB considers the payment status, collateralization levels, and borrower's financial condition to be indicators of credit quality for its credit products. At March 31, 2016 and December 31, 2015, the FHLB had rights to collateral on a member-by-member basis with an estimated value in excess of its outstanding extensions of credit.

The FHLB evaluates and makes changes to its collateral guidelines, as necessary, based on current market conditions. At March 31, 2016 and December 31, 2015, the FHLB did not have any Advances that were past due, in non-accrual status or impaired. In addition, there were no troubled debt restructurings related to credit products of the FHLB during three months endedMarch 31, 2016 or 2015.

The FHLB has not experienced any credit losses on Advances since it was founded in 1932. Based upon the collateral held as security, its credit extension and collateral policies and the repayment history on credit products, the FHLB did not record any credit losses on credit products as of March 31, 2016 or December 31, 2015. Accordingly, the FHLB did not record any allowance for credit losses on Advances.

At March 31, 2016 and December 31, 2015, the FHLB did not record any liability to reflect an allowance for credit losses for off-balance sheet credit exposures. See Note 19 for additional information on the FHLB's off-balance sheet credit exposure.

MortgageLoans Held for Portfolio- FHA

The FHLB invests in fixed-rate mortgage loans secured by one-to-four family residential properties insured by the FHA. The FHLB expects to recover any losses from such loans from the FHA. Any losses from these loans that are not recovered from the FHA would be due to a claim rejection by the FHA and, as such, would be recoverable from the selling participating financial institutions. Therefore, the FHLB only has credit risk for these loans if the seller or servicer fails to pay for losses not covered by the FHA insurance. As a result, the FHLB did not establish an allowance for credit losses on its FHA insured mortgage loans. Furthermore, due to the insurance, none of these mortgage loans have been placed on non-accrual status.

Mortgage Loans Held for Portfolio - Conventional Mortgage Purchase Program (MPP)

The FHLB determines the allowance for conventional loans through analyses that include consideration of various data observations such as past performance, current performance, loan portfolio characteristics, collateral-related characteristics, industry data, and prevailing economic conditions. The measurement of the allowance for credit losses consists of: (1) collectively evaluating homogeneous pools of residential mortgage loans; (2) reviewing specifically identified loans for impairment; and (3) considering other relevant qualitative factors.

Collectively Evaluated Mortgage Loans. The credit risk analysis of conventional loans evaluated collectively for impairment considers historical delinquency migration, applies estimated loss severities, and incorporates the associated credit enhancements in order to determine the FHLB's best estimate of probable incurred losses at the reporting date. The FHLB performs the credit risk analysis of all conventional mortgage loans at the individual Master Commitment Contract level to properly determine the credit enhancements available to recover losses on loans under each individual Master Commitment Contract. The Master Commitment Contract is an agreement with a member in which the member agrees to make a best efforts attempt to sell a specific dollar amount of loans to the FHLB generally over a one-year period. Migration analysis is a methodology for determining, through the FHLB's experience over a historical period, the rate of default on loans. The FHLB applies migration analysis to loans based on payment status categories such as current, 30, 60, and 90 days past due. The FHLB then estimates, based on historical experience, how many loans in these categories may migrate to a loss realization event and applies a current loss severity to estimate losses. The estimated losses are then reduced by the probable cash flows resulting from available credit enhancements. Any credit enhancement cash flows that are projected and assessed as not probable of receipt do not reduce estimated losses.

Individually Evaluated Mortgage Loans. Conventional mortgage loans that are considered troubled debt restructurings are specifically identified for purposes of calculating the allowance for credit losses. The FHLB measures impairment of these specifically identified loans by either estimating the present value of expected cash flows, estimating the loan's observable market price, or estimating the fair value of the collateral if the loan is collateral dependent. The FHLB removes specifically identified loans evaluated for impairment from the collectively evaluated mortgage loan population.

Qualitative Factors. The FHLB also assesses other qualitative factors in its estimation of loan losses for the collectively evaluated population. This amount represents a subjective management judgment, based on facts and circumstances that exist as of the reporting date, that is intended to cover other incurred losses that may not otherwise be captured in the methodology described above.

Rollforward of Allowance for Credit Losses on Mortgage Loans. The following tables present a rollforward of the allowance for credit losses on conventional mortgage loans as well as the recorded investment in mortgage loans by impairment methodology. The recorded investment in a loan is the unpaid principal balance of the loan adjusted for accrued interest, unamortized premiums or discounts, hedging basis adjustments and direct write-downs. The recorded investment is not net of any allowance.

Credit Enhancements. The conventional mortgage loans under the MPP are supported by some combination of credit enhancements (primary mortgage insurance (PMI), supplemental mortgage insurance (SMI) and the Lender Risk Account (LRA), including pooled LRA for those members participating in an aggregated MPP pool). The amount of credit enhancements needed to protect the FHLB against credit losses is determined through use of a third-party default model. These credit enhancements apply after a homeowner's equity is exhausted. Beginning in February 2011, the FHLB discontinued the use of SMI for all new loan purchases and replaced it with expanded use of the LRA. The LRA is funded by the FHLB as a portion of the purchase proceeds to cover expected losses. The LRA is recorded in other liabilities in the Statements of Condition. Excess funds over required balances are distributed to the member in accordance with a step-down schedule that is established upon execution of a Master Commitment Contract, subject to performance of the related loan pool. The LRA established for a pool of loans is limited to only covering losses of that specific pool of loans.

Troubled Debt Restructurings. A troubled debt restructuring is considered to have occurred when a concession is granted to a borrower for economic or legal reasons related to the borrower's financial difficulties and that concession would not have been considered otherwise. The FHLB's troubled debt restructurings primarily involve loans where an agreement permits the recapitalization of past due amounts up to the original loan amount and certain loans discharged in Chapter 7 bankruptcy. A loan considered a troubled debt restructuring is individually evaluated for impairment when determining its related allowance for credit losses. Credit loss is measured by factoring in expected cash shortfalls as of the reporting date.

The FHLB's recorded investment in modified loans considered troubled debt restructurings was (in thousands) $9,733 and $9,385 at March 31, 2016 and December 31, 2015, respectively. The amount of troubled debt restructurings is not considered material to the FHLB's financial condition, results of operations, or cash flows.

Derivatives and Hedging Activities

Nature of Business Activity

The FHLB is exposed to interest rate risk primarily from the effect of interest rate changes on its interest-earning assets and on the interest-bearing liabilities that finance these assets. The goal of the FHLB's interest-rate risk management strategy is not to eliminate interest-rate risk, but to manage it within appropriate limits. To mitigate the risk of loss, the FHLB has established policies and procedures, which include guidelines on the amount of exposure to interest rate changes it is willing to accept. In addition, the FHLB monitors the risk to its interest income, net interest margin and average maturity of interest-earning assets and interest-bearing liabilities. See Note 11 - Derivatives and Hedging Activities in the FHLB's 2015 Annual Report on Form 10-K for additional information on the FHLB's derivative transactions.

The FHLB uses derivatives when they are considered to be the most cost-effective alternative to achieve the FHLB's financial and risk management objectives. The FHLB re-evaluates its hedging strategies from time to time and may change the hedging techniques it uses or adopt new strategies.

The FHLB transacts its derivatives with large banks and major broker-dealers. Some of these banks and broker-dealers or their affiliates buy, sell, and distribute Consolidated Obligations. Derivative transactions may be either executed with a counterparty (uncleared derivatives) or cleared through a Futures Commission Merchant (i.e., clearing agent) with a Derivative Clearing Organization (cleared derivatives).

Once a derivative transaction has been accepted for clearing by a Derivative Clearing Organization (Clearinghouse), the derivative transaction is novated and the executing counterparty is replaced with the Clearinghouse. The FHLB is not a derivative dealer and does not trade derivatives for short-term profit.

Financial Statement Effect and Additional Financial Information

The notional amount of derivatives serves as a factor in determining periodic interest payments or cash flows received and paid. The notional amount reflects the FHLB's involvement in the various classes of financial instruments and represents neither the actual amounts exchanged nor the overall exposure of the FHLB to credit and market risk; the overall risk is much smaller. The risks of derivatives only can be measured meaningfully on a portfolio basis that takes into account the derivatives, the items being hedged and any offsets between the derivatives and the items being hedged.

Table 10.1 summarizes the fair value of derivative instruments, including the effect of netting adjustments and cash collateral. For purposes of this disclosure, the derivative values include the fair value of derivatives and the related accrued interest.

Credit Risk on Derivatives

The FHLB is subject to credit risk due to the risk of non-performance by counterparties to its derivative transactions and manages credit risk through credit analysis, collateral requirements and adherence to the requirements set forth in its policies, U.S. Commodity Futures Trading Commission regulations, and Finance Agency regulations. For uncleared derivatives, the degree of credit risk depends on the extent to which master netting arrangements are included in these contracts to mitigate the risk. The FHLB requires collateral agreements with collateral delivery thresholds on the majority of its uncleared derivatives.

For cleared derivatives, the Clearinghouse is the FHLB's counterparty. The Clearinghouse notifies the clearing agent of the required initial and variation margin and the clearing agent in turn notifies the FHLB. The requirement that the FHLB post initial and variation margin through the clearing agent, to the Clearinghouse, exposes the FHLB to credit risk if the clearing agent or the Clearinghouse fails to meet its obligations. The use of cleared derivatives is intended to mitigate credit risk exposure because a central counterparty is substituted for individual counterparties and collateral for changes in the value of cleared derivatives is posted daily through a clearing agent.

The FHLB has analyzed the enforceability of offsetting rights incorporated in its cleared derivative transactions and determined that the exercise of those offsetting rights by a non-defaulting party under these transactions should be upheld under applicable law upon an event of default including bankruptcy, insolvency, or similar proceeding involving the Clearinghouse or the FHLB's clearing agent, or both. Based on this analysis, the FHLB presents a net derivative receivable or payable for all of its transactions through a particular clearing agent with a particular Clearinghouse.

Certain of the FHLB's uncleared derivative contracts contain provisions that require the FHLB to post additional collateral with its counterparties if there is deterioration in the FHLB's credit ratings. The aggregate fair value of all uncleared derivatives with credit-risk-related contingent features that were in a net liability position (before cash collateral and related accrued interest) at March 31, 2016 was (in thousands) $66,838, for which the FHLB had posted collateral with a fair value of (in thousands) $35,390 in the normal course of business.

If one of the FHLB's credit ratings had been lowered to the next lower rating that would have triggered additional collateral to be delivered, the FHLB would have been required to deliver up to an additional (in thousands) $5,864 of collateral at fair value to its derivatives counterparties at March 31, 2016.

For cleared derivatives, the Clearinghouse determines initial margin requirements and generally credit ratings are not factored into the initial margin. However, clearing agents may require additional initial margin to be posted based on credit considerations, including, but not limited to, credit rating downgrades. At March 31, 2016, the FHLB was not required to post additional initial margin by its clearing agents based on credit considerations.

Offsetting of Derivative Assets and Derivative Liabilities

The FHLB presents derivative instruments, related cash collateral, including initial and variation margin, received or pledged, and associated accrued interest, on a net basis by clearing agent and/or by counterparty when it has met the netting requirements.

Table 10.4 presents separately the fair value of derivative instruments meeting or not meeting netting requirements, including the related collateral received from or pledged to counterparties. At March 31, 2016 and December 31, 2015, the FHLB did not receive or pledge any non-cash collateral. Any overcollateralization under an individual clearing agent and/or counterparty level is not included in the determination of the net unsecured amount.

Pension and Other Postretirement Benefits Disclosure [Text Block]

Pension and Postretirement Benefit Plans

Qualified Defined Benefit Multi-employer Plan. The FHLB participates in the Pentegra Defined Benefit Plan for Financial Institutions (Pentegra Defined Benefit Plan), a tax-qualified defined benefit pension plan. Under the Pentegra Defined Benefit Plan, contributions made by one participating employer may be used to provide benefits to employees of other participating employers because assets contributed by an employer are not segregated in a separate account or restricted to provide benefits only to employees of that employer. Also, in the event a participating employer is unable to meet its contribution requirements, the required contributions for the other participating employers could increase proportionately. The Pentegra Defined Benefit Plan covers substantially all officers and employees of the FHLB who meet certain eligibility requirements. Contributions to the Pentegra Defined Benefit Plan charged to compensation and benefit expense were $1,685,000 and $1,500,000 in the three months endedMarch 31, 2016 and 2015, respectively.

Qualified Defined Contribution Plan. The FHLB also participates in the Pentegra Defined Contribution Plan for Financial Institutions, a tax-qualified, defined contribution pension plan. The FHLB 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 FHLB contributed $387,000 and $374,000 in the three months endedMarch 31, 2016 and 2015, respectively.

Nonqualified Supplemental Defined Benefit Retirement Plan. The FHLB maintains a nonqualified, unfunded defined benefit plan. The plan ensures that participants receive the full amount of benefits to which they would have been entitled under the qualified defined benefit plan in the absence of limits on benefit levels imposed by the IRS. There are no funded plan assets. The FHLB has established a grantor trust, which is included in held-to-maturity securities on the Statements of Condition, to meet future benefit obligations and current payments to beneficiaries.

Postretirement Benefits Plan. The FHLB also sponsors a postretirement benefits plan that includes health care and life insurance benefits for eligible retirees. Future retirees are eligible for the postretirement benefits plan if they were hired prior to August 1, 1990, are age 55 or older, and their age plus years of continuous service at retirement are greater than or equal to 80. Spouses are covered subject to required contributions. There are no funded plan assets that have been designated to provide postretirement benefits.

Segment Information

The FHLB has identified two primary operating segments based on its method of internal reporting: Traditional Member Finance and the MPP. These segments reflect the FHLB's two primary Mission Asset Activities and the manner in which they are managed from the perspective of development, resource allocation, product delivery, pricing, credit risk and operational administration. The segments identify the principal ways the FHLB provides services to member stockholders.

Fair Value Disclosures

Fair Value Disclosures [Abstract]

Fair Value Disclosures [Text Block]

Fair Value Disclosures

The fair value amounts recorded on the Statements of Condition and presented in the related note disclosures have been determined by the FHLB using available market information and the FHLB's best judgment of appropriate valuation methods. The fair values reflect the FHLB's judgment of how a market participant would estimate the fair values.

Fair Value Hierarchy. The FHLB records trading securities, available-for-sale securities, derivative assets, derivative liabilities, certain Advances and certain Consolidated Obligation Bonds at fair value on a recurring basis, and on occasion, certain mortgage loans held for portfolio on a nonrecurring basis. GAAP establishes a fair value hierarchy and requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The inputs are evaluated and an overall level for the measurement is determined. This overall level is an indication of how market observable the fair value measurement is. An entity must disclose the level within the fair value hierarchy in which the measurements are classified.

The fair value hierarchy prioritizes the inputs used to measure fair value into three broad levels:

Level 1 Inputs - Quoted prices (unadjusted) for identical assets or liabilities in an active market that the reporting entity can access on the measurement date.

Level 2 Inputs - Inputs other than quoted prices within Level 1 that are observable inputs for the asset or liability, either directly or indirectly. If the asset or liability has a specified (contractual) term, a Level 2 input must be observable for substantially the full term of the asset or liability. Level 2 inputs include the following: (1) quoted prices for similar assets or liabilities in active markets; (2) quoted prices for identical or similar assets or liabilities in markets that are not active; (3) inputs other than quoted prices that are observable for the asset or liability (e.g., interest rates and yield curves that are observable at commonly quoted intervals, and implied volatilities); and (4) inputs that are derived principally from or corroborated by observable market data by correlation or other means.

Level 3 Inputs - Unobservable inputs for the asset or liability.

The FHLB reviews the fair value hierarchy classifications on a quarterly basis. Changes in the observability of the valuation inputs may result in a reclassification of certain financial assets or liabilities. Such reclassifications are reported as transfers in/out at fair value as of the beginning of the quarter in which the changes occur. The FHLB did not have any transfers of assets or liabilities recorded at fair value on a recurring basis during the three months endedMarch 31, 2016 or 2015.

Table 18.1 presents the carrying value, fair value, and fair value hierarchy of financial assets and liabilities of the FHLB. These values do not represent an estimate of the overall market value of the FHLB as a going concern, which would take into account future business opportunities and the net profitability of assets versus liabilities.

Fair Value Option. The fair value option provides an irrevocable option to elect fair value as an alternative measurement for selected financial assets, financial liabilities, unrecognized firm commitments, and written loan commitments not previously carried at fair value. It requires a company to display the fair value of those assets and liabilities for which it has chosen to use fair value on the face of the Statements of Condition. Fair value is used for both the initial and subsequent measurement of the designated assets, liabilities and commitments, with the changes in fair value recognized in net income. If elected, interest income and interest expense on Advances and Consolidated Bonds carried at fair value are recognized based solely on the contractual amount of interest due or unpaid. Any transaction fees or costs are immediately recognized into other non-interest income or other non-interest expense.

The FHLB has elected the fair value option for certain financial instruments that either do not qualify for hedge accounting or may be at risk for not meeting hedge effectiveness requirements. These fair value elections were made primarily in an effort to mitigate the potential income statement volatility that can arise from economic hedging relationships in which the carrying value of the hedged item is not adjusted for changes in fair value.

For instruments recorded under the fair value option, the related contractual interest income and contractual interest expense are recorded as part of net interest income on the Statements of Income. The remaining changes in fair value for instruments in which the fair value option has been elected are recorded as “Net losses on financial instruments held under fair value option” in the Statements of Income. The FHLB has determined that no adjustments to the fair values of its instruments recorded under the fair value option for instrument-specific credit risk were necessary as of March 31, 2016 or December 31, 2015.

The following table reflects the difference between the aggregate unpaid principal balance outstanding and the aggregate fair value for Advances and Consolidated Bonds for which the fair value option has been elected.

Legal Proceedings. From time to time, the FHLB is subject to legal proceedings arising in the normal course of business. In March 2010, the FHLB was advised by representatives of the Lehman Brothers Holdings, Inc. bankruptcy estate that they believed that the FHLB had been unjustly enriched in connection with the close out of its interest rate swap transactions with Lehman at the time of the Lehman bankruptcy in 2008 and that the bankruptcy estate was entitled to the $43 million difference between the settlement amount the FHLB paid Lehman in connection with the close-out transactions and the market value payment the FHLB received when replacing the swaps with other counterparties. In May 2010, the FHLB received a Derivatives Alternative Dispute Resolution notice from the Lehman bankruptcy estate with a settlement demand of $65.8 million, plus interest accruing primarily at LIBOR plus 14.5 percent since the bankruptcy filing, based on their view of how the settlement amount should have been calculated. In accordance with the Alternative Dispute Resolution Order of the Bankruptcy Court administering the Lehman estate, senior management of the FHLB participated in a non-binding mediation in New York in August 2010, and counsel for the FHLB continued discussions with the court-appointed mediator for several weeks thereafter. The mediation concluded in October 2010 without a settlement of the claims asserted by the Lehman bankruptcy estate. In April 2013, Lehman Brothers Special Financing Inc., through Lehman Brothers Holdings Inc. and the Plan Administrator under the Modified Third Amended Joint Chapter 11 Plan of Lehman Brothers Holdings Inc. and its Affiliated Debtors, filed an adversary complaint in the United States Bankruptcy Court for the Southern District of New York against the FHLB seeking (a) a declaratory judgment on the interpretation of certain provisions and the calculation of amounts due under the agreement governing the 2008 swap transactions described above, and (b) additional amounts alleged as due as part of the termination of such transactions. The FHLB believes that it correctly calculated, and fully satisfied its obligation to Lehman in September 2008, and the FHLB intends to vigorously defend itself.

The FHLB also is subject to other legal proceedings arising in the normal course of business. The FHLB would record an accrual for a loss contingency when it is probable that a loss has been incurred and the amount can be reasonably estimated. After consultation with legal counsel, management does not anticipate that the ultimate liability, if any, arising out of these matters will have a material effect on the FHLB's financial condition or results of operations.

Transactions with Other FHLBanks

The FHLB notes all transactions with other FHLBanks on the face of its financial statements. Occasionally, the FHLB loans short-term funds to and borrows short-term funds from other FHLBanks. These loans and borrowings are transacted at then current market rates when traded. There were no such loans or borrowings outstanding at March 31, 2016 or December 31, 2015 and no such transactions occurred during the three months endedMarch 31, 2016 and 2015.

In addition, the FHLB may, from time to time, assume the outstanding primary liability for Consolidated Obligations of another FHLBank (at then current market rates on the day when the transfer is traded) rather than issuing new debt for which the FHLB is the primary obligor. The FHLB then becomes the primary obligor on the transferred debt. There were no Consolidated Obligations transferred to the FHLB during the three months endedMarch 31, 2016 or 2015. The FHLB had no Consolidated Obligations transferred to other FHLBanks during these periods.

Transactions with Directors' Financial Institutions. In the ordinary course of its business, the FHLB may provide products and services to members whose officers or directors serve as directors of the FHLB (Directors' Financial Institutions). Finance Agency regulations require that transactions with Directors' Financial Institutions be made on the same terms as those with any other member. The following table reflects balances with Directors' Financial Institutions for the items indicated below. The FHLB had no mortgage-backed securities or derivatives transactions with Directors' Financial Institutions at March 31, 2016 or December 31, 2015.

Nonmember Affiliates. The FHLB has relationships with three nonmember affiliates, the Kentucky Housing Corporation, the Ohio Housing Finance Agency and the Tennessee Housing Development Agency. The FHLB had no investments in or borrowings to any of these nonmember affiliates at March 31, 2016 or December 31, 2015. The FHLB has executed standby bond purchase agreements with one state housing authority whereby the FHLB, for a fee, agrees as a liquidity provider if required, to purchase and hold the authority's bonds until the designated marketing agent can find a suitable investor or the housing authority repurchases the bond according to a schedule established by the standby agreement. During the first three months of 2016 and 2015, the FHLB was not required to purchase any bonds under these agreements.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]

Finance, Loan and Lease Receivables, Held-for-investment, Allowance and Nonperforming Loans, Nonperforming Loans Policy [Policy Text Block]

MortgageLoans Held for Portfolio- FHA

The FHLB invests in fixed-rate mortgage loans secured by one-to-four family residential properties insured by the FHA. The FHLB expects to recover any losses from such loans from the FHA. Any losses from these loans that are not recovered from the FHA would be due to a claim rejection by the FHA and, as such, would be recoverable from the selling participating financial institutions. Therefore, the FHLB only has credit risk for these loans if the seller or servicer fails to pay for losses not covered by the FHA insurance. As a result, the FHLB did not establish an allowance for credit losses on its FHA insured mortgage loans. Furthermore, due to the insurance, none of these mortgage loans have been placed on non-accrual status.

Mortgage Loans Held for Portfolio - Conventional Mortgage Purchase Program (MPP)

The FHLB determines the allowance for conventional loans through analyses that include consideration of various data observations such as past performance, current performance, loan portfolio characteristics, collateral-related characteristics, industry data, and prevailing economic conditions. The measurement of the allowance for credit losses consists of: (1) collectively evaluating homogeneous pools of residential mortgage loans; (2) reviewing specifically identified loans for impairment; and (3) considering other relevant qualitative factors.

Collectively Evaluated Mortgage Loans. The credit risk analysis of conventional loans evaluated collectively for impairment considers historical delinquency migration, applies estimated loss severities, and incorporates the associated credit enhancements in order to determine the FHLB's best estimate of probable incurred losses at the reporting date. The FHLB performs the credit risk analysis of all conventional mortgage loans at the individual Master Commitment Contract level to properly determine the credit enhancements available to recover losses on loans under each individual Master Commitment Contract. The Master Commitment Contract is an agreement with a member in which the member agrees to make a best efforts attempt to sell a specific dollar amount of loans to the FHLB generally over a one-year period. Migration analysis is a methodology for determining, through the FHLB's experience over a historical period, the rate of default on loans. The FHLB applies migration analysis to loans based on payment status categories such as current, 30, 60, and 90 days past due. The FHLB then estimates, based on historical experience, how many loans in these categories may migrate to a loss realization event and applies a current loss severity to estimate losses. The estimated losses are then reduced by the probable cash flows resulting from available credit enhancements. Any credit enhancement cash flows that are projected and assessed as not probable of receipt do not reduce estimated losses.

Individually Evaluated Mortgage Loans. Conventional mortgage loans that are considered troubled debt restructurings are specifically identified for purposes of calculating the allowance for credit losses. The FHLB measures impairment of these specifically identified loans by either estimating the present value of expected cash flows, estimating the loan's observable market price, or estimating the fair value of the collateral if the loan is collateral dependent. The FHLB removes specifically identified loans evaluated for impairment from the collectively evaluated mortgage loan population.

Qualitative Factors. The FHLB also assesses other qualitative factors in its estimation of loan losses for the collectively evaluated population. This amount represents a subjective management judgment, based on facts and circumstances that exist as of the reporting date, that is intended to cover other incurred losses that may not otherwise be captured in the methodology described above.

Loans and Leases Receivable, Troubled Debt Restructuring Policy [Policy Text Block]

A loan considered a troubled debt restructuring is individually evaluated for impairment when determining its related allowance for credit losses. Credit loss is measured by factoring in expected cash shortfalls as of the reporting date.

Segment Reporting, Policy [Policy Text Block]

The FHLB has identified two primary operating segments based on its method of internal reporting: Traditional Member Finance and the MPP. These segments reflect the FHLB's two primary Mission Asset Activities and the manner in which they are managed from the perspective of development, resource allocation, product delivery, pricing, credit risk and operational administration. The segments identify the principal ways the FHLB provides services to member stockholders.

Fair Value of Financial Instruments, Policy [Policy Text Block]

The fair value amounts recorded on the Statements of Condition and presented in the related note disclosures have been determined by the FHLB using available market information and the FHLB's best judgment of appropriate valuation methods. The fair values reflect the FHLB's judgment of how a market participant would estimate the fair values.

Fair Value Transfer, Policy [Policy Text Block]

The FHLB reviews the fair value hierarchy classifications on a quarterly basis. Changes in the observability of the valuation inputs may result in a reclassification of certain financial assets or liabilities. Such reclassifications are reported as transfers in/out at fair value as of the beginning of the quarter in which the changes occur.
