Accounting Policies [Abstract]
Basis of Presentation and Significant Accounting Policies	BASIS OF PRESENTATION Basis of Presentation: The accompanying interim financial statements of FHLBank are unaudited and have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) for interim financial information and with the instruction provided by Article 10, Rule 10-01 of Regulation S-X. The financial statements contain all adjustments which are, in the opinion of management, necessary for a fair statement of FHLBank’s financial position, results of operations and cash flows for the interim periods presented. All such adjustments were of a normal recurring nature. The results of operations for the periods presented are not necessarily indicative of the results to be expected for the full fiscal year or any other interim period. FHLBank’s significant accounting policies and certain other disclosures are set forth in the notes to the audited financial statements for the year ended December 31, 2019. The interim financial statements presented herein should be read in conjunction with FHLBank’s audited financial statements and notes thereto, which are included in FHLBank’s annual report on Form 10-K filed with the Securities and Exchange Commission (SEC) on March 20, 2020 (annual report on Form 10-K). The notes to the interim financial statements highlight significant changes to the notes included in the annual report on Form 10-K. Out-of-Period Adjustment: Included in net income for the three months ended September 30, 2019 was an out-of-period adjustment of $14,336,000, of which $2,545,000 and $11,791,000 related to income that should have been recorded during the three months ended March 31, 2019 and June 30, 2019, respectively. The out-of-period adjustment related to hedged item valuations for certain available-for-sale securities in fair value hedging relationships and resulted in an increase in available-for-sale interest income and a reduction in other comprehensive income. Consequently, available-for-sale interest income was understated by $11,791,000 and $14,336,000 for the three and six months ended June 30, 2019. FHLBank has assessed the impact of this error and concluded that the amounts were not material, either individually or in the aggregate, to any prior period financial statements. Use of Estimates : The preparation of financial statements under GAAP requires management to make estimates and assumptions as of the date of the financial statements in determining the reported amounts of assets, liabilities and estimated fair values and in determining the disclosure of any contingent assets or liabilities. Estimates and assumptions by management also affect the reported amounts of income and expense during the reporting period. The most significant of these estimates include the fair value of trading and available-for-sale securities and the fair value of derivatives. Many of the estimates and assumptions, including those used in financial models, are based on financial market conditions as of the date of the financial statements. Because of the volatility of the financial markets, as well as other factors that affect management estimates, actual results may vary from these estimates. Allowance for Credit Losses: Beginning January 1, 2020, FHLBank adopted new accounting guidance pertaining to the measurement of credit losses on financial instruments that requires a financial asset or group of financial assets measured at amortized cost to be presented at the net amount expected to be collected. The new guidance also requires credit losses relating to these financial instruments as well as available-for-sale securities to be recorded through an allowance for credit losses. Key changes as compared to prior accounting guidance are detailed below. Consistent with the modified retrospective method of adoption, the prior period has not been revised to conform to the new basis of accounting. See Note 1 of the Notes to the Financial Statements included in the annual report on Form 10-K for information on the prior accounting treatment. Interest-Bearing Deposits, Securities Purchased under Agreements to Resell, and Federal Funds Sold: FHLBank invests in interest-bearing deposits, securities purchased under agreements to resell, and Federal funds sold. These investments provide short-term liquidity and are carried at amortized cost. Accrued interest receivable is recorded separately on the Statements of Condition. These investments are evaluated quarterly for expected credit losses. If applicable, an allowance for credit losses is recorded with a corresponding adjustment to the provision (reversal) for credit losses. FHLBank uses the collateral maintenance provision practical expedient for securities purchased under agreements to resell. Consequently, a credit loss would be recognized if there is a collateral shortfall which FHLBank does not believe the counterparty will replenish in accordance with its contractual terms. The credit loss would be limited to the difference between the fair value of the collateral and the investment’s amortized cost. See Note 3 for details on the allowance methodologies relating to these investments. Investment Securities: Available-for-Sale: For securities classified as available-for-sale, FHLBank evaluates an individual security for impairment on a quarterly basis by comparing the security’s fair value to its amortized cost. Accrued interest receivable is recorded separately on the Statements of Condition. Impairment exists when the fair value of the investment is less than its amortized cost (i.e., in an unrealized loss position). In assessing whether a credit loss exists on an impaired security, FHLBank considers whether there would be a shortfall in receiving all cash flows contractually due. When a shortfall is considered possible, FHLBank compares the present value of cash flows to be collected from the security with the amortized cost basis of the security. If the present value of cash flows is less than amortized cost, an allowance for credit losses is recorded with a corresponding adjustment to the provision (reversal) for credit losses. The allowance is limited by the amount of the unrealized loss. The allowance for credit losses excludes uncollectible accrued interest receivable, which is measured separately. If management intends to sell an impaired security classified as available-for-sale, or more likely than not will be required to sell the security before expected recovery of its amortized cost basis, any allowance for credit losses is written off and the amortized cost basis is written down to the security’s fair value at the reporting date with any incremental impairment reported in earnings as net gains (losses) on available-for-sale securities. If management does not intend to sell an impaired security classified as available-for-sale and it is not more likely than not that management will be required to sell the debt security, then the credit portion of the difference is recognized as an allowance for credit losses and any remaining difference between the security’s fair value and amortized cost is recorded to net unrealized gains (losses) on available-for-sale securities within other comprehensive income (loss) (OCI). Held-to-Maturity: Securities that FHLBank has both the ability and intent to hold to maturity are classified as held-to-maturity and are carried at amortized cost, adjusted for periodic principal repayments, amortization of premiums, and accretion of discounts. Accrued interest receivable is recorded separately on the Statements of Condition. Held-to-maturity securities are evaluated quarterly for expected credit losses on a pool basis unless an individual assessment is deemed necessary because the securities do not possess similar risk characteristics. An allowance for credit losses is recorded with a corresponding adjustment to the provision (reversal) for credit losses. The allowance for credit losses excludes uncollectible accrued interest receivable, which is measured separately. See Note 3 for details on the allowance methodologies relating to available-for-sale and held-to-maturity securities. Advances: Advances are carried at amortized cost, which is original cost adjusted for periodic principal repayments, amortization of premiums, accretion of discounts, and fair value hedge adjustments. Accrued interest receivable is recorded separately on the Statements of Condition. Advances are evaluated quarterly for expected credit losses. If deemed necessary, an allowance for credit losses is recorded with a corresponding adjustment to the provision (reversal) for credit losses. See Note 4 for details on the allowance methodology relating to advances. Mortgage Loans Held for Portfolio: Mortgage loans held for portfolio are recorded at amortized cost, which is original cost adjusted for periodic principal repayments, amortization of premiums, accretion of discounts, hedging adjustments, other fees, and direct write-downs. Accrued interest receivable is recorded separately on the Statements of Condition. FHLBank performs a quarterly assessment of its mortgage loans held for portfolio to estimate expected credit losses. An allowance for credit losses is recorded with a corresponding adjustment to the provision (reversal) for credit losses. FHLBank measures expected credit losses on mortgage loans on a collective basis, pooling loans with similar risk characteristics. If a mortgage loan no longer shares risk characteristics with other loans, it is removed from the pool and evaluated for expected credit losses on an individual basis. When developing the allowance for credit losses, FHLBank measures the estimated loss over the remaining life of a mortgage loan, which also considers how credit enhancements mitigate credit losses. If a loan is purchased at a discount, the discount does not offset the allowance for credit losses. The allowance excludes uncollectible accrued interest receivable, as FHLBank writes off accrued interest receivable by reversing interest income if a mortgage loan is placed on nonaccrual status. FHLBank does not purchase mortgage loans with credit deterioration present at the time of purchase. FHLBank includes estimates of expected recoveries within the allowance for credit losses. See Note 5 for details on the allowance methodologies relating to mortgage loans. Off-Balance Sheet Credit Exposures: FHLBank evaluates off-balance sheet credit exposures on a quarterly basis for expected credit losses. If deemed necessary, an allowance for expected credit losses on these off-balance sheet exposures is recorded in other liabilities with a corresponding adjustment to the provision (reversal) for credit losses. See Note 13 for details on the allowance methodologies relating to off-balance sheet credit exposures.

Accounting Standards Update and Change in Accounting Principle [Abstract]
Recently Issued Accounting Standards And Interpretations And Changes In And Adoptions Of Accounting Principles	RECENTLY ISSUED ACCOUNTING STANDARDS AND INTERPRETATIONS AND CHANGES IN AND ADOPTIONS OF ACCOUNTING PRINCIPLES Coronavirus Aid, Relief, and Economic Security Act (CARES Act). In March 2020, the CARES Act was signed into law to provide relief from the economic impact of the COVID-19 pandemic to a variety of sectors of the U.S. economy, including businesses, individuals, health care, education, and state and local governments. The CARES Act also includes provisions that provide optional relief from certain accounting and reporting requirements related to troubled debt restructurings (TDRs). TDR relief applies to COVID-19-related modifications made from March 1, 2020 until the earlier of December 31, 2020 or 60 days following the termination of the national emergency declared by the President of the United States for borrowers that were current as of December 31, 2019. FHLBank has elected the optional relief but does not expect it to have a material effect on FHLBank's financial condition, results of operations, cash flows, or disclosures. Facilitation of the Effects of Reference Rate Reform on Financial Reporting (Accounting Standard Update (ASU) 2020-04) . In March 2020, the Financial Accounting Standards Board (FASB) issued temporary optional guidance to ease the potential burden in accounting for reference rate reform. The new guidance provides optional expedients and exceptions for applying GAAP to transactions affected by reference rate reform if certain criteria are met. The transactions primarily include: (1) contract modifications; (2) hedging relationships; and (3) sale or transfer of debt securities classified as held-to-maturity. This guidance was effective immediately for FHLBank, and the amendments may be applied prospectively through December 31, 2022. FHLBank is in the process of evaluating the guidance, and its effect on FHLBank's financial condition, results of operations and cash flows has not yet been determined. Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract (ASU 2018-15). In August 2018, the FASB issued an amendment to align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). Accordingly, the amendments in this ASU require an entity in a hosting arrangement that is a service contract to follow existing guidance relating to internal-use software to determine which implementation costs to capitalize as an asset related to the service contract and which costs to expense. Costs to develop or obtain internal-use software that cannot be capitalized also cannot be capitalized for a hosting arrangement that is a service contract. Therefore, an entity in a hosting arrangement that is a service contract determines to which project stage (that is, preliminary project stage, application development stage, or post-implementation stage) an implementation activity relates. Costs for implementation activities in the application development stage are capitalized depending on the nature of the costs, while costs incurred during the preliminary project and post-implementation stages are expensed as the activities are performed. The amendments in this ASU also require the entity to expense the capitalized implementation costs of a hosting arrangement that is a service contract over the term of the hosting arrangement. The amendments in this ASU were effective January 1, 2020 for FHLBank. The adoption of this guidance did not materially impact FHLBank's financial condition, results of operations or cash flows. Changes to the Disclosure Requirements for Defined Benefit Plans (ASU 2018-14). In August 2018, the FASB issued an amendment modifying the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans to improve disclosure effectiveness. The amendments in the ASU remove disclosures that are no longer considered cost beneficial, clarify the specific requirements of disclosures, and add disclosure requirements identified as relevant. The amendments in this ASU are effective for annual periods ending after December 15, 2020, which is the year ending December 31, 2020 for FHLBank, and will be applied retrospectively for all comparative periods presented. The adoption of this guidance will not have a material impact on the disclosures related to defined benefit plans and will not impact FHLBank’s financial condition, results of operations or cash flows. Changes to the Disclosure Requirements for Fair Value Measurement (ASU 2018-13). In August 2018, the FASB issued an amendment that modifies the disclosure requirements for fair value measurements. This ASU removes the requirement to disclose: (1) the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy; (2) the policy for timing of transfers between levels; and (3) the valuation processes for Level 3 fair value measurements. The ASU requires disclosure of changes in unrealized gains and losses for the period included in OCI for recurring Level 3 fair value measurements held at the end of the reporting period and the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. The amendments in this ASU were effective January 1, 2020 for FHLBank. The adoption of this guidance did not have an impact on the disclosures related to fair value measurements and did not impact FHLBank’s financial condition, results of operations or cash flows. Measurement of Credit Losses on Financial Instruments, as amended (ASU 2016-13). In June 2016, the FASB issued amended guidance for the accounting of credit losses on financial instruments. The amendments require entities to measure expected credit losses based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. An entity must use judgment in determining the relevant information and estimation methods that are appropriate in its circumstances. Additionally, under the new guidance, a financial asset, or a group of financial assets, measured at amortized cost basis is required to be presented at the net amount expected to be collected. The guidance also requires: ▪ The statement of income to reflect the measurement of credit losses for newly recognized financial assets, as well as the expected increases or decreases of expected credit losses that have taken place during the period; ▪ The entities to determine the allowance for credit losses for purchased financial assets with a more-than-insignificant amount of credit deterioration since origination that are measured at amortized cost basis in a similar manner to other financial assets measured at amortized cost basis. The initial allowance for credit losses is required to be added to the purchase price; ▪ Credit losses relating to available-for-sale debt securities to be recorded through an allowance for credit losses. The amendments limit the allowance for credit losses to the amount by which fair value is below amortized cost; and ▪ Public entities to further disaggregate the current disclosure of credit quality indicators in relation to the amortized cost of financing receivables by the year of origination (i.e., vintage). The guidance became effective for FHLBank on January 1, 2020 and was applied using a modified-retrospective approach, through a cumulative-effect adjustment to retained earnings. Adoption of this guidance did not materially impact FHLBank’s financial condition, results of operations, or cash flows.

Investments, Debt and Equity Securities [Abstract]
Investment Securities	INVESTMENTS FHLBank's investment portfolio consists of interest-bearing deposits, securities purchased under agreements to resell, Federal funds sold, and debt securities. Interest-Bearing Deposits, Securities Purchased under Agreements to Resell, and Federal Funds Sold: FHLBank invests in interest-bearing deposits, securities purchased under agreements to resell, and Federal funds sold to provide short-term liquidity. These investments are generally transacted with counterparties that have received a credit rating of triple-B or greater (investment grade) by a nationally recognized statistical rating organization (NRSRO). These may differ from internal ratings of the investments, if applicable. As of September 30, 2020, approximately 70 percent of these overnight investments were with counterparties not rated by an NRSRO. All transactions with unrated counterparties are secured transactions. Federal funds sold are unsecured loans that are generally transacted on an overnight term. Federal Housing Finance Agency (FHFA) regulations include a limit on the amount of unsecured credit FHLBank may extend to a counterparty. As of September 30, 2020 and December 31, 2019, all investments in interest-bearing deposits and Federal funds sold were repaid or expected to be repaid according to the contractual terms. No allowance for credit losses was recorded for these assets as of September 30, 2020 and December 31, 2019. Carrying values of interest-bearing deposits and Federal funds sold exclude accrued interest receivable of $83,000 and $3,000, respectively, as of September 30, 2020, and $589,000 and $30,000, respectively, as of December 31, 2019. Securities purchased under agreements to resell are short-term and are structured such that they are evaluated regularly to determine if the market value of the underlying securities decreases below the market value required as collateral (i.e., subject to collateral maintenance provisions). If so, the counterparty must place an equivalent amount of additional securities as collateral or remit an equivalent amount of cash, generally by the next business day. Based upon the collateral held as security and collateral maintenance provisions with its counterparties, FHLBank determined that no allowance for credit losses was needed for its securities purchased under agreements to resell as of September 30, 2020 and December 31, 2019. The carrying value of securities purchased under agreements excludes accrued interest receivable of $15,000 and $424,000 as of September 30, 2020 and December 31, 2019, respectively. Debt Securities: FHLBank invests in debt securities, which are classified as either trading, available-for-sale, or held-to-maturity. FHLBank is prohibited by FHFA regulations from purchasing certain higher-risk securities, such as equity securities and debt instruments that are not investment quality, other than certain investments targeted at low-income persons or communities and instruments that experienced credit deterioration after their purchase by FHLBank. FHLBank's debt securities include the following major security types, which are based on the issuer and the risk characteristics of the security: ▪ Certificates of deposit - unsecured negotiable promissory notes issued by banks; ▪ U.S. Treasury obligations - sovereign debt of the United States; ▪ GSE obligations - debentures issued by other FHLBanks, Federal National Mortgage Association (Fannie Mae), Federal Farm Credit Bank and Federal Agricultural Mortgage Corporation. GSE securities are not guaranteed by the U.S. government; ▪ State or local housing agency obligations - municipal bonds issued by housing finance agencies; ▪ U.S. obligation MBS - single-family MBS issued by Government National Mortgage Association (Ginnie Mae), which are guaranteed by the U.S. government; and ▪ GSE MBS - single-family and multifamily MBS issued by Fannie Mae and Federal Home Loan Mortgage Corporation (Freddie Mac).

FHLBank adopted new accounting guidance for the measurement of credit losses on financial instruments on January 1, 2020. See Note 2 for additional information. During the three and nine months ended September 30, 2020, FHLBank did not recognize a provision for credit losses associated with available-for-sale investments or held-to-maturity investments. To evaluate investment securities for credit loss as of September 30, 2020, FHLBank employed the following methodologies, based on the type of security. FHLBank's available-for-sale and held-to-maturity securities are principally certificates of deposit, U.S. obligations, GSE obligations, state or local housing agency obligations, and MBS issued by Ginnie Mae, Freddie Mac, and Fannie Mae that are backed by single-family or multifamily mortgage loans. FHLBank only purchases securities considered investment quality. As of September 30, 2020, all of FHLBank's available-for-sale securities and held-to-maturity securities were rated single-A or above by an NRSRO, based on the lowest long-term credit rating for each security. These may differ from any internal ratings of the securities, if applicable.

Advances [Abstract]
Advances	ADVANCES General Terms: FHLBank offers a wide range of fixed and variable rate advance products with different maturities, interest rates, payment characteristics and optionality. As of September 30, 2020 and December 31, 2019, FHLBank had advances outstanding at interest rates ranging from 0.14 percent to 7.20 percent and 0.96 percent to 7.41 percent, respectively, for traditional advances (excludes COVID-19 Relief Advances described below). Table 4.1 presents advances summarized by redemption term as of September 30, 2020 and December 31, 2019 (dollar amounts in thousands). Carrying amounts exclude accrued interest receivable of $15,186,000 and $45,637,000 as of September 30, 2020 and December 31, 2019, respectively.

The zero-cost advances have a term of 6 months and the low-cost advances have terms between 6 and 24 months. As of September 30, 2020, FHLBank had $517,351,000 and $501,890,000 of zero-cost and low-cost advances outstanding, respectively. Discounts were initially recorded on these advances and are accreted using the interest method over the life of the advances resulting in the recognition of periodic interest income on the advances at the effective interest rate (i.e., yield recorded equals a prevailing rate) in net interest income. As of September 30, 2020, the total unaccreted discount balance was $2,455,000. FHLBank’s outstanding advances include advances that contain call options that may be exercised with or without prepayment fees at the borrower’s discretion on specific dates (call dates) before the stated advance maturities (callable advances). In exchange for receiving the right to call the advance on a predetermined call schedule, the borrower may pay a higher fixed rate for the advance relative to an equivalent maturity, non-callable, fixed rate advance. The borrower normally exercises its call options on these advances when interest rates decline (fixed rate advances) or spreads change (adjustable rate advances). Convertible advances allow FHLBank to convert an advance from one interest payment term structure to another. When issuing convertible advances, FHLBank purchases put options from a member that allow FHLBank to convert the fixed rate advance to a variable rate advance at the current market rate or another structure after an agreed-upon lockout period. A convertible advance carries a lower interest rate than a comparable-maturity fixed rate advance without the conversion feature. Table 4.2 presents advances summarized by redemption term or next call date (for callable advances) and by redemption term or next conversion date (for convertible advances) as of September 30, 2020 and December 31, 2019 (in thousands): Table 4.2 Redemption Term Redemption Term Redemption Term 09/30/2020 12/31/2019 09/30/2020 12/31/2019 Due in one year or less $ 15,561,420 $ 24,271,238 $ 14,625,732 $ 14,053,068 Due after one year through two years 1,383,709 1,133,077 2,263,896 10,637,833 Due after two years through three years 822,894 728,429 1,305,837 1,524,153 Due after three years through four years 795,261 764,990 1,338,888 1,215,412 Due after four years through five years 779,961 686,594 1,214,303 1,304,254 Thereafter 2,963,587 2,587,727 1,558,176 1,437,335 TOTAL PAR VALUE $ 22,306,832 $ 30,172,055 $ 22,306,832 $ 30,172,055 Interest Rate Payment Terms : Table 4.3 details additional interest rate payment terms for advances as of September 30, 2020 and December 31, 2019 (in thousands): Table 4.3 Redemption Term 09/30/2020 12/31/2019 Fixed rate: Due in one year or less $ 9,999,404 $ 2,691,528 Due after one year 6,671,538 5,912,124 Total fixed rate 16,670,942 8,603,652 Variable rate: Due in one year or less 3,589,578 10,496,590 Due after one year 2,046,312 11,071,813 Total variable rate 5,635,890 21,568,403 TOTAL PAR VALUE $ 22,306,832 $ 30,172,055 Credit Risk Exposure and Security Terms: FHLBank's advances are primarily made to member financial institutions, including commercial banks and insurance companies. FHLBank manages its credit exposure to advances through an integrated approach that includes establishing a credit limit for each borrower. This approach includes an ongoing review of each borrower's financial condition, in conjunction with FHLBank's collateral and lending policies to limit risk of loss, while balancing borrowers' needs for a reliable source of funding. In addition, FHLBank lends to eligible borrowers in accordance with federal law and FHFA regulations. Specifically, FHLBank is required to obtain sufficient collateral to fully secure credit products up to the counterparty’s total credit limit. Collateral eligible to secure new or renewed advances includes: ▪ One-to-four family and multifamily mortgage loans (delinquent for no more than 90 days) and securities representing such mortgages; ▪ Loans and securities issued, insured, or guaranteed by the U.S. government or any U.S. government agency (for example, MBS issued or guaranteed by Fannie Mae, Freddie Mac, or Ginnie Mae); ▪ Cash or deposits in FHLBank; ▪ Certain other collateral that is real estate-related, provided that the collateral has a readily ascertainable value and that FHLBank can perfect a security interest in it; and ▪ Certain qualifying securities representing undivided equity interests in eligible advance collateral. During the second quarter of 2020, FHLBank was given the regulatory flexibility via a Supervisory Letter from the FHFA to allow members to pledge Small Business Administration (SBA) Paycheck Protection Program (PPP) loans as eligible collateral, with the following restrictions: (1) maximum aggregate lending value for PPP loans is limited to the lesser of $5 billion or 20 percent of the institution’s total lending value on all collateral pledged; and (2) the institution must maintain a CAMELS composite rating of “3” or better. CAMELS is a rating system for banks utilized by federal banking supervisors that represents an evaluation of a bank's financial condition and compliance with laws and regulatory policies. If an institution’s CAMELS composite rating downgrades to “4” or “5”, the institution must substitute all PPP loans being utilized to support outstanding credit obligations with other eligible collateral within five business days. As of September 30, 2020, the amount of PPP loans pledged to FHLBank as collateral was insignificant. Residential mortgage loans are the principal form of collateral for advances. The estimated value of the collateral required to secure each member's credit products is calculated by applying collateral discounts, or haircuts, to the market value or unpaid principal balance of the collateral, as applicable. In addition, community financial institutions are eligible to use expanded statutory collateral provisions for small business, agriculture loans, and community development loans. FHLBank capital stock owned by each borrower is also pledged as collateral. Collateral arrangements may vary depending upon borrower credit quality, financial condition, and performance; borrowing capacity; and overall credit exposure to the borrower. FHLBank can also require additional or substitute collateral to protect its security interest. FHLBanks also have policies and procedures for validating the reasonableness of their collateral valuations. In addition, collateral verifications and on-site reviews are performed by FHLBank based on the risk profile of the borrower. FHLBank management believes that these policies effectively manage credit risk from advances. The FHFA has provided non-objection relief via a Supervisory Letter that permits FHLBank to offer its members increased collateral flexibility through the acceptance of various types of forbearance plans and loan modification agreements of the Temporary COVID-19 Underwriting Guidelines in the first quarter of 2020. FHLBank management and the board of directors has approved as collateral forbearance plans and loan modification agreements for the following loan categories: conventional mortgages on one-to-four family residential real property, mortgages on multifamily residential real property, agricultural real estate, commercial real estate, second mortgages on residential one-to-four family property, home equity lines of credit, operating loans, and equipment loans. In addition, the temporary guidelines allow flexibility to accept loans as collateral that have modifications or forbearance plans executed via electronic signature in compliance with the Electronic Signatures in Global and National Commerce Act (i.e., E-SIGN). At the of the third quarter of 2020, the Temporary COVID-19 Underwriting Guidelines continue to be available for use by members. FHLBank either allows a borrower to retain physical possession of the collateral assigned to it, or requires the borrower to specifically assign or place physical possession of the collateral with FHLBank or its safekeeping agent. FHLBank perfects its security interest in all pledged collateral. The Federal Home Loan Bank Act of 1932, as amended, (Bank Act) states that any security interest granted to an FHLBank by a borrower will have 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 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 and taking into consideration each borrower's financial strength, FHLBank considers the types and level of collateral to be the primary indicator of credit quality on advances. As of September 30, 2020 and December 31, 2019, FHLBank had rights to collateral on a borrower-by-borrower basis with an estimated value greater than its outstanding advances. FHLBank continues to evaluate and make changes to its collateral guidelines, as necessary, based on current market conditions. As of September 30, 2020 and December 31, 2019, no advances were past due, on non-accrual status, or considered impaired. In addition, there were no troubled debt restructurings related to advances during the three and nine months ended September 30, 2020 and 2019.

Receivables [Abstract]
Mortgage Loans	MORTGAGE LOANS Mortgage loans held for portfolio consist of loans obtained through the MPF Program and are either conventional mortgage loans or government-guaranteed or -insured mortgage loans. Under the MPF Program, FHLBank purchases single-family mortgage loans that are originated or acquired by participating financial institutions (PFIs). These mortgage loans are credit-enhanced by PFIs or are guaranteed or insured by Federal agencies. Mortgage Loans Held for Portfolio: Table 5.1 presents information as of September 30, 2020 and December 31, 2019 on mortgage loans held for portfolio (in thousands). Mortgage loans held for portfolio excludes accrued interest receivable of $48,406,000 and $52,358,000 as of September 30, 2020 and December 31, 2019, respectively.

Table 5.2 presents information as of September 30, 2020 and December 31, 2019 on the outstanding unpaid principal balance of mortgage loans held for portfolio (in thousands): Table 5.2 09/30/2020 12/31/2019 Conventional loans $ 9,405,054 $ 9,849,542 Government-guaranteed or -insured loans 558,098 626,111 TOTAL UNPAID PRINCIPAL BALANCE $ 9,963,152 $ 10,475,653 Credit Enhancements: FHLBank's allowance for credit losses considers the credit enhancements associated with conventional mortgage loans under the MPF Program. Credit enhancements may include primary mortgage insurance, supplemental mortgage insurance and the credit enhancement amount plus any recoverable performance-based credit enhancement fees (for certain MPF loans). Potential recoveries from credit enhancements for conventional loans are evaluated at the individual master commitment level to determine the credit enhancements available to recover losses on loans under each individual master commitment. Payment Status of Mortgage Loans: Payment status is the key credit quality indicator for conventional mortgage loans and allows FHLBank to monitor the migration of past due loans. Past due loans are those where the borrower has failed to make timely payments of principal and/or interest in accordance with the terms of the loan. Other delinquency statistics include non-accrual loans and loans in process of foreclosure. Table 5.3 presents the payment status based on amortized cost as well as other delinquency statistics for FHLBank’s mortgage loans as of September 30, 2020 (dollar amounts in thousands): Table 5.3 09/30/2020 Conventional Loans Government Total Origination Year Subtotal Prior to 2016 2016 2017 2018 2019 2020 Amortized Cost: 1 Past due 30-59 days delinquent $ 16,140 $ 2,749 $ 8,132 $ 7,949 $ 19,111 $ 3,470 $ 57,551 $ 11,657 $ 69,208 Past due 60-89 days delinquent 9,267 1,812 2,924 3,265 9,102 1,878 28,248 5,969 34,217 Past due 90 days or more delinquent 24,992 4,012 14,965 22,618 49,602 4,488 120,677 22,928 143,605 Total past due 50,399 8,573 26,021 33,832 77,815 9,836 206,476 40,554 247,030 Total current loans 2,179,738 713,694 795,307 815,417 2,754,390 2,070,784 9,329,330 525,032 9,854,362 Total mortgage loans $ 2,230,137 $ 722,267 $ 821,328 $ 849,249 $ 2,832,205 $ 2,080,620 $ 9,535,806 $ 565,586 $ 10,101,392 Other delinquency statistics: In process of foreclosure 2 $ 162,584 $ 9,341 $ 171,925 Serious delinquency rate 3 2.1 % 4.7 % 2.3 % Past due 90 days or more and still accruing interest $ — $ 22,928 $ 22,928 Loans on non-accrual status 4 $ 129,118 $ — $ 129,118 1 Excludes accrued interest receivable. 2 Includes loans where the decision of foreclosure or similar alternative such as pursuit of deed-in-lieu has been reported. Loans in process of foreclosure are included in past due or current loans dependent on their delinquency status. 3 Loans that are 90 days or more past due or in the process of foreclosure expressed as a percentage of the total amortized cost for the portfolio class. 4 Loans on non-accrual status include $1,251,000 of troubled debt restructurings. Troubled debt restructurings are restructurings in which FHLBank, for economic or legal reasons related to the debtor’s financial difficulties, grants a concession to the debtor that it would not otherwise consider. FHLBank's servicers may grant a forbearance period to borrowers who have requested forbearance based on COVID-19-related difficulties regardless of the status of the loan at the time of the request. FHLBank continues to apply its accounting policy for past due loans and charge-offs to loans during the forbearance period whether it be formal or informal. The accrual status for a loan under forbearance will be driven by the past due status of the loan without consideration of the forbearance as the legal terms of the contractual arrangement have not been modified. As of September 30, 2020, there was $132,932,000, or 1.4 percent, of unpaid principal balances of conventional loans in a forbearance plan as a result of COVID-19, representing $5,118,000, $13,665,000, $17,744,000, and $96,405,000 with payment status of current, 30 to 59 days past due, 60 to 89 days past due, and greater than 90 days past due, respectively. Table 5.4 presents the payment status based on recorded investment as well as other delinquency statistics for FHLBank’s mortgage loans as of December 31, 2019 (dollar amounts in thousands): Table 5.4 12/31/2019 Conventional Government Total Recorded investment: 1 Past due 30-59 days delinquent $ 59,226 $ 15,515 $ 74,741 Past due 60-89 days delinquent 7,561 6,128 13,689 Past due 90 days or more delinquent 11,813 8,778 20,591 Total past due 78,600 30,421 109,021 Total current loans 9,969,930 607,400 10,577,330 Total recorded investment $ 10,048,530 $ 637,821 $ 10,686,351 Other delinquency statistics: In process of foreclosure 2 $ 3,352 $ 2,730 $ 6,082 Serious delinquency rate 3 0.1 % 1.4 % 0.1 % Past due 90 days or more and still accruing interest $ — $ 8,778 $ 8,778 Loans on non-accrual status 4 $ 14,923 $ — $ 14,923 1 Includes accrued interest receivable. 2 Includes loans where the decision of foreclosure or similar alternative such as pursuit of deed-in-lieu has been reported. Loans in process of foreclosure are included in past due or current loans dependent on their delinquency status. 3 Loans that are 90 days or more past due or in the process of foreclosure expressed as a percentage of the total recorded investment for the portfolio class. 4 Loans on non-accrual status include $1,219,000 of troubled debt restructurings. Troubled debt restructurings are restructurings in which FHLBank, for economic or legal reasons related to the debtor’s financial difficulties, grants a concession to the debtor that it would not otherwise consider. Allowance for Credit Losses: Conventional Mortgage Loans: Conventional loans are evaluated collectively when similar risk characteristics exists. Conventional loans that do not share risk characteristics with other pools are evaluated for expected credit losses on an individual basis. FHLBank determines its allowances for credit losses on conventional loans through analyses that include consideration of various loan portfolio and collateral-related characteristics, such as past performance, current conditions, and reasonable and supportable forecasts of expected economic conditions. FHLBank uses a model that discounts projected cash flows to estimate expected credit losses over the life of the loans. This model relies on a number of inputs, such as both current and forecasted property values and interest rates as well as historical borrower behavior experience. FHLBank also incorporates associated credit enhancements, as available, to determine its estimate of expected credit losses. Certain conventional loans may be evaluated for credit losses using the practical expedient for collateral dependent assets. A mortgage loan is considered collateral dependent if repayment is expected to be provided by the sale of the underlying property, that is, if it is considered likely that the borrower will default. FHLBank may estimate the fair value of this collateral by applying an appropriate loss severity rate or using third party estimates or property valuation model(s). The expected credit loss of a collateral dependent mortgage loan is equal to the difference between the amortized cost of the loan and the estimated fair value of the collateral, less estimated selling costs. FHLBank records a direct charge-off of the loan balance, if certain triggering criteria are met. Expected recoveries of prior charge-offs, if any, are included in the allowance for credit losses. FHLBank established an allowance for credit losses on its conventional mortgage loans held for portfolio. Table 5.5 presents a roll-forward of the allowance for credit losses on mortgage loans for the three and nine months ended September 30, 2020 and 2019.

The maximum credit risk applicable to a single counterparty was $500,000 and $211,000 as of September 30, 2020 and December 31, 2019, respectively. The counterparty was different for each period. For uncleared derivative transactions, FHLBank has entered into bilateral security agreements with its counterparties with bilateral-collateral-exchange provisions that require all credit exposures be collateralized, subject to minimum transfer amounts. FHLBank utilizes two Derivative Clearing Organizations (Clearinghouse) for all cleared derivative transactions, LCH Limited and CME Clearing. At both Clearinghouses, initial margin is considered cash collateral. 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. FHLBank was not required to post additional initial margin by its clearing agents as of September 30, 2020 and December 31, 2019. FHLBank’s net exposure on derivative agreements is presented in Note 9.

FHLBank’s participation in consolidated obligation bonds outstanding as of September 30, 2020 and December 31, 2019 includes callable bonds totaling $6,465,000,000 and $8,891,500,000, respectively. FHLBank uses the unswapped callable bonds for financing its callable fixed rate advances (Note 4), MBS (Note 3) and mortgage loans (Note 5). Contemporaneous with a portion of its fixed rate callable bond issuances, FHLBank also enters into interest rate swap agreements (in which FHLBank generally pays a variable rate and receives a fixed rate) with call features that mirror the options in the callable bonds (a sold callable swap). The combined sold callable swap and callable debt transaction allows FHLBank to obtain attractively priced variable rate financing.

Offsetting [Abstract]
Assets and Liabilities Subject to Offsetting	ASSETS AND LIABILITIES SUBJECT TO OFFSETTING FHLBank presents certain financial instruments, including derivatives, repurchase agreements and securities purchased under agreements to resell, on a net basis by clearing agent by Clearinghouse, or by counterparty, when it has met the netting requirements. For these financial instruments, FHLBank has elected to offset its asset and liability positions, as well as cash collateral received or pledged, including associated accrued interest. FHLBank 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 a bankruptcy, insolvency, or similar proceeding involving the Clearinghouse or clearing agent, or both. Based on this analysis, FHLBank presents a net derivative receivable or payable for all of its transactions through a particular clearing agent with a particular Clearinghouse. Tables 9.1 and 9.2 present the fair value of financial assets, including the related collateral received from or pledged to clearing agents or counterparties, based on the terms of FHLBank’s master netting arrangements or similar agreements as of September 30, 2020 and December 31, 2019 (in thousands): Table 9.1 09/30/2020 Description Gross Amounts Gross Amounts Net Amounts Gross Amounts Not Offset in the Statement of Condition 1 Net Derivative assets: Uncleared derivatives $ 19,682 $ (15,472) $ 4,210 $ (84) $ 4,126 Cleared derivatives 1,471 156,820 158,291 — 158,291 Total derivative assets 21,153 141,348 162,501 (84) 162,417 Securities purchased under agreements to resell 4,600,000 — 4,600,000 (4,600,000) — TOTAL $ 4,621,153 $ 141,348 $ 4,762,501 $ (4,600,084) $ 162,417 1 Represents noncash collateral received on financial instruments that: (1) do not qualify for netting on the Statements of Condition; or (2) are not subject to an enforceable netting agreement (e.g., mortgage delivery commitments).

Capital

Stockholders' Equity Note [Abstract]
Capital	CAPITAL Capital Requirements: FHLBank is subject to three capital requirements under the provisions of the Gramm-Leach-Bliley Act (GLB Act) and the FHFA's capital structure regulation. Regulatory capital does not include AOCI but does include mandatorily redeemable capital stock. • Risk-based capital. FHLBank must maintain at all times permanent capital in an amount at least equal to the sum of its credit risk, market risk and operations risk capital requirements. The risk-based capital requirements are all calculated in accordance with the rules and regulations of the FHFA. Only permanent capital, defined as Class B Common Stock and retained earnings, can be used by FHLBank to satisfy its risk-based capital requirement. The FHFA may require FHLBank to maintain a greater amount of permanent capital than is required by the risk-based capital requirement as defined, but the FHFA has not placed any such requirement on FHLBank to date. • Total regulatory capital. The GLB Act requires FHLBank to maintain at all times at least a 4.0 percent total capital-to-asset ratio. Total regulatory capital is defined as the sum of permanent capital, Class A Common Stock, any general loss allowance, if consistent with GAAP and not established for specific assets, and other amounts from sources determined by the FHFA as available to absorb losses. • Leverage capital. FHLBank is required to maintain at all times a leverage capital-to-assets ratio of at least 5.0 percent, with the leverage capital ratio defined as the sum of permanent capital weighted 1.5 times and non-permanent capital (currently only Class A Common Stock) weighted 1.0 times, divided by total assets. Table 10.1 illustrates that FHLBank was in compliance with its regulatory capital requirements as of September 30, 2020 and December 31, 2019 (dollar amounts in thousands): Table 10.1 09/30/2020 12/31/2019 Required Actual Required Actual Regulatory capital requirements: Risk-based capital $ 206,942 $ 2,216,737 $ 486,650 $ 2,319,531 Total regulatory capital-to-asset ratio 4.0 % 4.9 % 4.0 % 4.4 % Total regulatory capital $ 2,120,455 $ 2,605,221 $ 2,531,066 $ 2,768,680 Leverage capital ratio 5.0 % 7.0 % 5.0 % 6.2 % Leverage capital $ 2,650,569 $ 3,713,590 $ 3,163,833 $ 3,928,446 Mandatorily Redeemable Capital Stock: FHLBank is a cooperative whose members own most of FHLBank’s capital stock. Former members (including certain non-members that own FHLBank capital stock as a result of merger or acquisition, relocation, charter termination, or involuntary termination of an FHLBank member) own the remaining capital stock to support business transactions still carried on FHLBank's Statements of Condition. Shares cannot be purchased or sold except between FHLBank and its members at a price equal to the $100 per share par value. If a member cancels its written notice of redemption or notice of withdrawal, FHLBank will reclassify mandatorily redeemable capital stock from a liability to equity. After the reclassification, dividends on the capital stock would no longer be classified as interest expense. Table 10.2 presents a roll-forward of mandatorily redeemable capital stock for the three and nine months ended September 30, 2020 and 2019 (in thousands): Table 10.2 Three Months Ended Nine Months Ended 09/30/2020 09/30/2019 09/30/2020 09/30/2019 Balance, beginning of period $ 2,308 $ 2,750 $ 2,415 $ 3,597 Capital stock subject to mandatory redemption reclassified from equity during the period 620,561 159,775 1,627,899 218,411 Capital stock redemption cancellations reclassified to equity during the period — — (100,647) — Redemption or repurchase of mandatorily redeemable capital stock during the period (620,967) (160,078) (1,527,802) (219,642) Stock dividend classified as mandatorily redeemable capital stock during the period 12 30 49 111 Balance, end of period $ 1,914 $ 2,477 $ 1,914 $ 2,477 Table 10.3 shows the amount of mandatorily redeemable capital stock by contractual year of redemption as of September 30, 2020 and December 31, 2019 (in thousands). The year of redemption in Table 10.3 is the end of the redemption period in accordance with FHLBank’s capital plan. FHLBank is not required to redeem or repurchase membership stock until six months (for Class A Common Stock) or five years (for Class B Common Stock) after FHLBank receives notice for withdrawal from the member. Additionally, FHLBank is not required to redeem or repurchase activity-based stock until any activity-based stock becomes excess stock as a result of an activity no longer remaining outstanding. However, FHLBank intends to repurchase the excess activity-based stock of non-members to the extent that it can do so and still meet its regulatory capital requirements. Table 10.3 Contractual Year of Repurchase 09/30/2020 12/31/2019 Year 1 $ — $ — Year 2 636 1 Year 3 — 869 Year 4 — — Year 5 — — Past contractual redemption date due to remaining activity 1 1,278 1,545 TOTAL $ 1,914 $ 2,415 1 Represents mandatorily redeemable capital stock that is past the end of the contractual redemption period because there is activity outstanding to which the mandatorily redeemable capital stock relates. Excess Capital Stock: Excess capital stock is defined as the amount of stock held by a member (or former member) in excess of that institution’s minimum stock purchase requirement. FHFA rules limit the ability of FHLBank to create excess member stock under certain circumstances. For example, FHLBank may not pay dividends in the form of capital stock or issue new excess stock to members if FHLBank’s excess stock exceeds one percent of its total assets or if the issuance of excess stock would cause FHLBank’s excess stock to exceed one percent of its total assets. As of September 30, 2020, FHLBank’s excess stock was less than one percent of total assets. Capital Classification Determination: The FHFA determines each FHLBank’s capital classification on at least a quarterly basis. If an FHLBank is determined to be other than adequately capitalized, that FHLBank becomes subject to additional supervisory authority by the FHFA. Before implementing a reclassification, the Director of the FHFA is required to provide an FHLBank with written notice of the proposed action and an opportunity to submit a response. As of the most recent review by the FHFA, FHLBank Topeka was classified as adequately capitalized. Partial Recovery of Prior Capital Distribution to Financing Corporation . The Competitive Equality Banking Act of 1987 was enacted in August 1987, which, among other things, provided for the recapitalization of the Federal Savings and Loan Insurance Corporation through a newly-chartered entity, the Financing Corporation. The capitalization of the Financing Corporation was provided by capital distributions from the FHLBanks to the Financing Corporation in exchange for Financing Corporation nonvoting capital stock. Capital distributions were made by the FHLBanks in 1987, 1988 and 1989 that aggregated to $680,000,000. Upon passage of Financial Institutions Reform, Recovery and Enforcement Act of 1989, the FHLBanks’ previous investment in capital stock of the Financing Corporation was determined to be non-redeemable and the FHLBanks charged-off their prior capital distributions to the Financing Corporation directly against retained earnings. Upon the dissolution of the Financing Corporation in June 2020, the Financing Corporation determined that excess funds aggregating to $200,031,000 were available for distribution to its stockholders, the FHLBanks. Specifically, FHLBank Topeka’s partial recovery of prior capital distribution was $10,543,000, which was determined based on its share of the $680,000,000 originally contributed. The FHLBanks treated the receipt of these funds as a return of the FHLBanks’ investment in Financing Corporation capital stock, and therefore as a partial recovery of the prior capital distributions made by the FHLBanks to the Financing Corporation in 1987, 1988, and 1989. These funds have been credited to unrestricted retained earnings.

Fair Values

Fair Value Disclosures [Abstract]
Fair Values	FAIR VALUES The fair value amounts recorded on the Statements of Condition and presented in the note disclosures have been determined by FHLBank using available market and other pertinent information and reflect FHLBank’s best judgment of appropriate valuation methods. GAAP defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (i.e., an exit price). Although FHLBank uses its best judgment in estimating the fair value of its financial instruments, there are inherent limitations in any valuation technique. Therefore, the fair values may not be indicative of the amounts that would have been realized in market transactions as of September 30, 2020 and December 31, 2019. Additionally, these values do not represent an estimate of the overall market value of FHLBank as a going concern, which would take into account future business opportunities and the net profitability of assets and liabilities. Subjectivity of Estimates: Estimates of the fair value of advances with options, mortgage instruments, derivatives with embedded options and consolidated obligation bonds with options are highly subjective and require judgments regarding significant matters such as the amount and timing of future cash flows, prepayment speed assumptions, expected interest rate volatility, methods to determine possible distributions of future interest rates used to value options, and the selection of discount rates that appropriately reflect market and credit risks. The use of different assumptions could have a material effect on the fair value estimates. Fair Value Hierarchy: The fair value hierarchy requires FHLBank 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 fair value measurement is determined. This overall level is an indication of the market observability of the fair value measurement for the asset or liability. FHLBank must disclose the level within the fair value hierarchy in which the measurements are classified for all assets and liabilities. 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 active markets that FHLBank can access on the measurement date. An active market for the asset or liability is a market in which the transactions for the asset or liability occur with sufficient frequency and volume to provide pricing information on an ongoing basis. • 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 and liabilities in active markets; (2) quoted prices for similar assets and 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. FHLBank reviews its fair value hierarchy classifications on a quarterly basis. Changes in the observability of the valuation inputs may result in a reclassification of certain assets or liabilities. There were no transfers of assets or liabilities between fair value levels during the three and nine months ended September 30, 2020 and 2019. Tables 12.1 and 12.2 present the carrying value, fair value and fair value hierarchy of financial assets and liabilities as of September 30, 2020 and December 31, 2019. FHLBank records trading securities, available-for-sale securities, derivative assets, and derivative liabilities at fair value on a recurring basis, and on occasion certain mortgage loans held for portfolio and certain other assets at fair value on a nonrecurring basis. FHLBank measures all other financial assets and liabilities at amortized cost. Further details about the financial assets and liabilities held at fair value on either a recurring or non-recurring basis are presented in Tables 12.3 and 12.4. The carrying value, fair value and fair value hierarchy of FHLBank’s financial assets and liabilities as of September 30, 2020 and December 31, 2019 are summarized in Tables 12.1 and 12.2 (in thousands): Table 12.1 09/30/2020 Carrying Total Level 1 Level 2 Level 3 Netting Adjustment and Cash Collateral 1 Assets: Cash and due from banks $ 22,704 $ 22,704 $ 22,704 $ — $ — $ — Interest-bearing deposits 499,662 499,662 — 499,662 — — Securities purchased under agreements to resell 4,600,000 4,600,000 — 4,600,000 — — Federal funds sold 1,435,000 1,435,000 — 1,435,000 — — Trading securities 3,117,935 3,117,935 — 3,117,935 — — Available-for-sale securities 7,290,611 7,290,611 — 7,290,611 — — Held-to-maturity securities 2,973,976 2,975,782 — 2,897,278 78,504 — Advances 22,616,252 22,733,051 — 22,733,051 — — Mortgage loans held for portfolio, net of allowance 10,093,466 10,351,013 — 10,348,886 2,127 — Accrued interest receivable 108,532 108,532 — 108,532 — — Derivative assets 162,501 162,501 — 21,153 — 141,348 Liabilities: Deposits 1,016,316 1,016,316 — 1,016,316 — — Consolidated obligation discount notes 11,936,214 11,936,578 — 11,936,578 — — Consolidated obligation bonds 37,294,169 37,517,293 — 37,517,293 — — Mandatorily redeemable capital stock 1,914 1,914 1,914 — — — Accrued interest payable 54,913 54,913 — 54,913 — — Derivative liabilities 173 173 — 370,663 — (370,490) Other Asset (Liability): Industrial revenue bonds 35,000 38,224 — 38,224 — — Financing obligation payable (35,000) (38,224) — (38,224) — — 1 Represents the effect of legally enforceable master netting agreements that allow FHLBank to net settle positive and negative positions and also derivative cash collateral and related accrued interest held or placed with the same clearing agent or derivative counterparty.

Commitments and Contingencies Disclosure [Abstract]
Commitments And Contingencies	COMMITMENTS AND CONTINGENCIES Joint and Several Liability: As provided in the Bank Act or in FHFA regulations, consolidated obligations are backed only by the financial resources of the FHLBanks. FHLBank Topeka is jointly and severally liable with the other FHLBanks for the payment of principal and interest on all of the consolidated obligations issued by the FHLBanks. The par amounts for which FHLBank Topeka is jointly and severally liable were approximately $770,698,374,000 and $966,413,924,000 as of September 30, 2020 and December 31, 2019, respectively. Off-balance Sheet Commitments: As of September 30, 2020 and December 31, 2019, off-balance sheet commitments are presented in Table 13.1 (in thousands): Table 13.1 09/30/2020 12/31/2019 Notional Amount Expire Expire Total Expire Expire Total Standby letters of credit outstanding $ 5,044,507 $ 4,635 $ 5,049,142 $ 4,764,724 $ 4,335 $ 4,769,059 Advance commitments outstanding 38,420 12,090 50,510 64,282 15,693 79,975 Commitments for standby bond purchases 423,030 280,733 703,763 — 701,392 701,392 Commitments to fund or purchase mortgage loans 105,003 — 105,003 221,800 — 221,800 Commitments to issue consolidated bonds, at par 264,000 — 264,000 — — — Commitments to issue consolidated discount notes, at par — — — 411,161 — 411,161 Commitments to Extend Credit: FHLBank issues standby letters of credit on behalf of its members to support certain obligations of the members to third-party beneficiaries. These standby letters of credit are subject to the same collateralization and borrowing limits that are applicable to advances and are fully collateralized at the time of issuance with assets allowed by FHLBank’s Member Products Policy (MPP). Standby letters of credit may be offered to assist members in facilitating residential housing finance, community lending, and asset-liability management, and to provide liquidity. In particular, members often use standby letters of credit as collateral for deposits from federal and state government agencies. Standby letters of credit are executed for members for a fee. If FHLBank is required to make payment for a beneficiary's draw, the member either reimburses FHLBank for the amount drawn or, subject to FHLBank's discretion, the amount drawn may be converted into a collateralized advance to the member. However, standby letters of credit usually expire without being drawn upon. Outstanding standby letters of credit have original or extended expiration periods of up to 6 years. FHLBank's current outstanding standby letters of credit expire no later than 2024. Unearned fees as well as the value of the guarantees related to standby letters of credit are recorded in other liabilities and amounted to $1,623,000 and $1,470,000 as of September 30, 2020 and December 31, 2019, respectively. Advance commitments legally bind and unconditionally obligate FHLBank for additional advances up to 24 months in the future. Based upon management’s credit analysis of members and collateral requirements under the MPP, FHLBank does not expect to incur any credit losses on the outstanding letters of credit or advance commitments. Standby Bond-Purchase Agreements: FHLBank has entered into standby bond purchase agreements with state housing authorities whereby FHLBank, for a fee, agrees to purchase and hold the authorities’ 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. Each standby agreement dictates the specific terms that would require FHLBank to purchase the bond. The bond purchase commitments entered into by FHLBank expire no later than 2023, though some are renewable at the option of FHLBank. As of September 30, 2020 and December 31, 2019, the total commitments for bond purchases included agreements with two in-district state housing authorities. FHLBank was required to purchase $122,390,000 in bonds under these agreements during the nine months ended September 30, 2020. These bonds were classified as available-for-sale securities, and were acquired at par and sold at par within the same month. FHLBank was not required to purchase any bonds under any agreements during the nine months ended September 30, 2019. Commitments to Purchase Mortgage Loans: These commitments that unconditionally obligate FHLBank to purchase mortgage loans from participating FHLBank Topeka members in the MPF Program are generally for periods not to exceed 60 calendar days. Certain commitments are recorded as derivatives at their fair values on the Statements of Condition. FHLBank recorded mortgage delivery commitment net derivative asset (liability) balances of $4,000 and $470,000 as of September 30, 2020 and December 31, 2019, respectively. Commitments to Issue Consolidated Obligations: FHLBank enters into commitments to issue consolidated obligation bonds and discount notes outstanding in the normal course of its business. Most settle within the shortest period possible and are considered regular way trades; however, certain commitments are recorded as derivatives at their fair values on the Statements of Condition.

Federal Home Loan Banks [Abstract]
Transactions With Stockholders	TRANSACTIONS WITH STOCKHOLDERS FHLBank is a cooperative whose members own most of the capital stock of FHLBank and generally receive dividends on their investments. In addition, certain former members that still have outstanding transactions are also required to maintain their investments in FHLBank capital stock until the transactions mature or are paid off. Nearly all outstanding advances are with current members, and the majority of outstanding mortgage loans held for portfolio were purchased from current or former members. FHLBank also maintains demand deposit accounts for members primarily to facilitate settlement activities that are directly related to advances and mortgage loan purchases. Transactions with members are entered into in the ordinary course of business. In instances where members also have officers or directors who are directors of FHLBank, transactions with those members are subject to the same eligibility and credit criteria, as well as the same terms and conditions, as other transactions with members. For financial reporting and disclosure purposes, FHLBank defines related parties as FHLBank directors’ financial institutions and members with capital stock investments in excess of 10 percent of FHLBank’s total regulatory capital stock outstanding, which includes mandatorily redeemable capital stock. Activity with Members that Exceed a 10 Percent Ownership in FHLBank Regulatory Capital Stock: Tables 14.1 and 14.2 present information on members that owned more than 10 percent of outstanding FHLBank regulatory capital stock as of September 30, 2020 and December 31, 2019 (dollar amounts in thousands).

FHLBank’s significant accounting policies and certain other disclosures are set forth in the notes to the audited financial statements for the year ended December 31, 2019. The interim financial statements presented herein should be read in conjunction with FHLBank’s audited financial statements and notes thereto, which are included in FHLBank’s annual report on Form 10-K filed with the Securities and Exchange Commission (SEC) on March 20, 2020 (annual report on Form 10-K). The notes to the interim financial statements highlight significant changes to the notes included in the annual report on Form 10-K.
Use Of Estimates, Policy	Use of Estimates : The preparation of financial statements under GAAP requires management to make estimates and assumptions as of the date of the financial statements in determining the reported amounts of assets, liabilities and estimated fair values and in determining the disclosure of any contingent assets or liabilities. Estimates and assumptions by management also affect the reported amounts of income and expense during the reporting period. The most significant of these estimates include the fair value of trading and available-for-sale securities and the fair value of derivatives. Many of the estimates and assumptions, including those used in financial models, are based on financial market conditions as of the date of the financial statements. Because of the volatility of the financial markets, as well as other factors that affect management estimates, actual results may vary from these estimates.
Credit Loss, Financial Instrument [Policy Text Block]	Beginning January 1, 2020, FHLBank adopted new accounting guidance pertaining to the measurement of credit losses on financial instruments that requires a financial asset or group of financial assets measured at amortized cost to be presented at the net amount expected to be collected. The new guidance also requires credit losses relating to these financial instruments as well as available-for-sale securities to be recorded through an allowance for credit losses. Key changes as compared to prior accounting guidance are detailed below. Consistent with the modified retrospective method of adoption, the prior period has not been revised to conform to the new basis of accounting. See Note 1 of the Notes to the Financial Statements included in the annual report on Form 10-K for information on the prior accounting treatment. Interest-Bearing Deposits, Securities Purchased under Agreements to Resell, and Federal Funds Sold: FHLBank invests in interest-bearing deposits, securities purchased under agreements to resell, and Federal funds sold. These investments provide short-term liquidity and are carried at amortized cost. Accrued interest receivable is recorded separately on the Statements of Condition. These investments are evaluated quarterly for expected credit losses. If applicable, an allowance for credit losses is recorded with a corresponding adjustment to the provision (reversal) for credit losses. FHLBank uses the collateral maintenance provision practical expedient for securities purchased under agreements to resell. Consequently, a credit loss would be recognized if there is a collateral shortfall which FHLBank does not believe the counterparty will replenish in accordance with its contractual terms. The credit loss would be limited to the difference between the fair value of the collateral and the investment’s amortized cost. See Note 3 for details on the allowance methodologies relating to these investments. Investment Securities: Available-for-Sale: For securities classified as available-for-sale, FHLBank evaluates an individual security for impairment on a quarterly basis by comparing the security’s fair value to its amortized cost. Accrued interest receivable is recorded separately on the Statements of Condition. Impairment exists when the fair value of the investment is less than its amortized cost (i.e., in an unrealized loss position). In assessing whether a credit loss exists on an impaired security, FHLBank considers whether there would be a shortfall in receiving all cash flows contractually due. When a shortfall is considered possible, FHLBank compares the present value of cash flows to be collected from the security with the amortized cost basis of the security. If the present value of cash flows is less than amortized cost, an allowance for credit losses is recorded with a corresponding adjustment to the provision (reversal) for credit losses. The allowance is limited by the amount of the unrealized loss. The allowance for credit losses excludes uncollectible accrued interest receivable, which is measured separately. If management intends to sell an impaired security classified as available-for-sale, or more likely than not will be required to sell the security before expected recovery of its amortized cost basis, any allowance for credit losses is written off and the amortized cost basis is written down to the security’s fair value at the reporting date with any incremental impairment reported in earnings as net gains (losses) on available-for-sale securities. If management does not intend to sell an impaired security classified as available-for-sale and it is not more likely than not that management will be required to sell the debt security, then the credit portion of the difference is recognized as an allowance for credit losses and any remaining difference between the security’s fair value and amortized cost is recorded to net unrealized gains (losses) on available-for-sale securities within other comprehensive income (loss) (OCI). Held-to-Maturity: Securities that FHLBank has both the ability and intent to hold to maturity are classified as held-to-maturity and are carried at amortized cost, adjusted for periodic principal repayments, amortization of premiums, and accretion of discounts. Accrued interest receivable is recorded separately on the Statements of Condition. Held-to-maturity securities are evaluated quarterly for expected credit losses on a pool basis unless an individual assessment is deemed necessary because the securities do not possess similar risk characteristics. An allowance for credit losses is recorded with a corresponding adjustment to the provision (reversal) for credit losses. The allowance for credit losses excludes uncollectible accrued interest receivable, which is measured separately. See Note 3 for details on the allowance methodologies relating to available-for-sale and held-to-maturity securities. Advances: Advances are carried at amortized cost, which is original cost adjusted for periodic principal repayments, amortization of premiums, accretion of discounts, and fair value hedge adjustments. Accrued interest receivable is recorded separately on the Statements of Condition. Advances are evaluated quarterly for expected credit losses. If deemed necessary, an allowance for credit losses is recorded with a corresponding adjustment to the provision (reversal) for credit losses. See Note 4 for details on the allowance methodology relating to advances. Mortgage Loans Held for Portfolio: Mortgage loans held for portfolio are recorded at amortized cost, which is original cost adjusted for periodic principal repayments, amortization of premiums, accretion of discounts, hedging adjustments, other fees, and direct write-downs. Accrued interest receivable is recorded separately on the Statements of Condition. FHLBank performs a quarterly assessment of its mortgage loans held for portfolio to estimate expected credit losses. An allowance for credit losses is recorded with a corresponding adjustment to the provision (reversal) for credit losses. FHLBank measures expected credit losses on mortgage loans on a collective basis, pooling loans with similar risk characteristics. If a mortgage loan no longer shares risk characteristics with other loans, it is removed from the pool and evaluated for expected credit losses on an individual basis. When developing the allowance for credit losses, FHLBank measures the estimated loss over the remaining life of a mortgage loan, which also considers how credit enhancements mitigate credit losses. If a loan is purchased at a discount, the discount does not offset the allowance for credit losses. The allowance excludes uncollectible accrued interest receivable, as FHLBank writes off accrued interest receivable by reversing interest income if a mortgage loan is placed on nonaccrual status. FHLBank does not purchase mortgage loans with credit deterioration present at the time of purchase. FHLBank includes estimates of expected recoveries within the allowance for credit losses. See Note 5 for details on the allowance methodologies relating to mortgage loans. Off-Balance Sheet Credit Exposures: FHLBank evaluates off-balance sheet credit exposures on a quarterly basis for expected credit losses. If deemed necessary, an allowance for expected credit losses on these off-balance sheet exposures is recorded in other liabilities with a corresponding adjustment to the provision (reversal) for credit losses. See Note 13 for details on the allowance methodologies relating to off-balance sheet credit exposures. Interest-Bearing Deposits, Securities Purchased under Agreements to Resell, and Federal Funds Sold: FHLBank invests in interest-bearing deposits, securities purchased under agreements to resell, and Federal funds sold to provide short-term liquidity. These investments are generally transacted with counterparties that have received a credit rating of triple-B or greater (investment grade) by a nationally recognized statistical rating organization (NRSRO). These may differ from internal ratings of the investments, if applicable. As of September 30, 2020, approximately 70 percent of these overnight investments were with counterparties not rated by an NRSRO. All transactions with unrated counterparties are secured transactions. Federal funds sold are unsecured loans that are generally transacted on an overnight term. Federal Housing Finance Agency (FHFA) regulations include a limit on the amount of unsecured credit FHLBank may extend to a counterparty. As of September 30, 2020 and December 31, 2019, all investments in interest-bearing deposits and Federal funds sold were repaid or expected to be repaid according to the contractual terms. No allowance for credit losses was recorded for these assets as of September 30, 2020 and December 31, 2019. Carrying values of interest-bearing deposits and Federal funds sold exclude accrued interest receivable of $83,000 and $3,000, respectively, as of September 30, 2020, and $589,000 and $30,000, respectively, as of December 31, 2019. Allowance for Credit Losses on Available-for-Sale and Held-to-Maturity Securities: FHLBank evaluates available-for-sale and held-to-maturity investment securities for credit losses on a quarterly basis. FHLBank adopted new accounting guidance for the measurement of credit losses on financial instruments on January 1, 2020. See Note 2 for additional information. During the three and nine months ended September 30, 2020, FHLBank did not recognize a provision for credit losses associated with available-for-sale investments or held-to-maturity investments. To evaluate investment securities for credit loss as of September 30, 2020, FHLBank employed the following methodologies, based on the type of security. FHLBank's available-for-sale and held-to-maturity securities are principally certificates of deposit, U.S. obligations, GSE obligations, state or local housing agency obligations, and MBS issued by Ginnie Mae, Freddie Mac, and Fannie Mae that are backed by single-family or multifamily mortgage loans. FHLBank only purchases securities considered investment quality. As of September 30, 2020, all of FHLBank's available-for-sale securities and held-to-maturity securities were rated single-A or above by an NRSRO, based on the lowest long-term credit rating for each security. These may differ from any internal ratings of the securities, if applicable. FHLBank evaluates available-for-sale securities for impairment by comparing the security’s fair value to its amortized cost. Impairment may exist when the fair value of the investment is less than its amortized cost (i.e., in an unrealized loss position). As of September 30, 2020, certain available-for-sale securities were in an unrealized loss position. These losses are considered temporary as FHLBank expects to recover the entire amortized cost basis on these available-for-sale investment securities. FHLBank neither intends to sell these securities nor considers it more likely than not that it will be required to sell these securities before its anticipated recovery of each security's remaining amortized cost basis. Further, FHLBank has not experienced any payment defaults on the instruments. In addition, all of these securities carry an implicit or explicit government guarantee. As a result, no allowance for credit losses was recorded on these available-for-sale securities as of September 30, 2020. FHLBank evaluates its held-to-maturity securities for impairment on a collective or pooled basis unless an individual assessment is deemed necessary because the securities do not possess similar risk characteristics. As of September 30, 2020, FHLBank had not established an allowance for credit loss on any held-to-maturity securities because the securities: (1) were all highly-rated and/or had short remaining terms to maturity; (2) had not experienced, nor did FHLBank expect, any payment default on the instruments; and (3) in the case of U.S. or GSE obligations, carry an implicit or explicit government guarantee such that FHLBank considers the risk of nonpayment to be zero. Credit Risk Exposure and Security Terms: FHLBank's advances are primarily made to member financial institutions, including commercial banks and insurance companies. FHLBank manages its credit exposure to advances through an integrated approach that includes establishing a credit limit for each borrower. This approach includes an ongoing review of each borrower's financial condition, in conjunction with FHLBank's collateral and lending policies to limit risk of loss, while balancing borrowers' needs for a reliable source of funding. In addition, FHLBank lends to eligible borrowers in accordance with federal law and FHFA regulations. Specifically, FHLBank is required to obtain sufficient collateral to fully secure credit products up to the counterparty’s total credit limit. Collateral eligible to secure new or renewed advances includes: ▪ One-to-four family and multifamily mortgage loans (delinquent for no more than 90 days) and securities representing such mortgages; ▪ Loans and securities issued, insured, or guaranteed by the U.S. government or any U.S. government agency (for example, MBS issued or guaranteed by Fannie Mae, Freddie Mac, or Ginnie Mae); ▪ Cash or deposits in FHLBank; ▪ Certain other collateral that is real estate-related, provided that the collateral has a readily ascertainable value and that FHLBank can perfect a security interest in it; and ▪ Certain qualifying securities representing undivided equity interests in eligible advance collateral. During the second quarter of 2020, FHLBank was given the regulatory flexibility via a Supervisory Letter from the FHFA to allow members to pledge Small Business Administration (SBA) Paycheck Protection Program (PPP) loans as eligible collateral, with the following restrictions: (1) maximum aggregate lending value for PPP loans is limited to the lesser of $5 billion or 20 percent of the institution’s total lending value on all collateral pledged; and (2) the institution must maintain a CAMELS composite rating of “3” or better. CAMELS is a rating system for banks utilized by federal banking supervisors that represents an evaluation of a bank's financial condition and compliance with laws and regulatory policies. If an institution’s CAMELS composite rating downgrades to “4” or “5”, the institution must substitute all PPP loans being utilized to support outstanding credit obligations with other eligible collateral within five business days. As of September 30, 2020, the amount of PPP loans pledged to FHLBank as collateral was insignificant. Residential mortgage loans are the principal form of collateral for advances. The estimated value of the collateral required to secure each member's credit products is calculated by applying collateral discounts, or haircuts, to the market value or unpaid principal balance of the collateral, as applicable. In addition, community financial institutions are eligible to use expanded statutory collateral provisions for small business, agriculture loans, and community development loans. FHLBank capital stock owned by each borrower is also pledged as collateral. Collateral arrangements may vary depending upon borrower credit quality, financial condition, and performance; borrowing capacity; and overall credit exposure to the borrower. FHLBank can also require additional or substitute collateral to protect its security interest. FHLBanks also have policies and procedures for validating the reasonableness of their collateral valuations. In addition, collateral verifications and on-site reviews are performed by FHLBank based on the risk profile of the borrower. FHLBank management believes that these policies effectively manage credit risk from advances. The FHFA has provided non-objection relief via a Supervisory Letter that permits FHLBank to offer its members increased collateral flexibility through the acceptance of various types of forbearance plans and loan modification agreements of the Temporary COVID-19 Underwriting Guidelines in the first quarter of 2020. FHLBank management and the board of directors has approved as collateral forbearance plans and loan modification agreements for the following loan categories: conventional mortgages on one-to-four family residential real property, mortgages on multifamily residential real property, agricultural real estate, commercial real estate, second mortgages on residential one-to-four family property, home equity lines of credit, operating loans, and equipment loans. In addition, the temporary guidelines allow flexibility to accept loans as collateral that have modifications or forbearance plans executed via electronic signature in compliance with the Electronic Signatures in Global and National Commerce Act (i.e., E-SIGN). At the of the third quarter of 2020, the Temporary COVID-19 Underwriting Guidelines continue to be available for use by members. FHLBank either allows a borrower to retain physical possession of the collateral assigned to it, or requires the borrower to specifically assign or place physical possession of the collateral with FHLBank or its safekeeping agent. FHLBank perfects its security interest in all pledged collateral. The Federal Home Loan Bank Act of 1932, as amended, (Bank Act) states that any security interest granted to an FHLBank by a borrower will have 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 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 and taking into consideration each borrower's financial strength, FHLBank considers the types and level of collateral to be the primary indicator of credit quality on advances. As of September 30, 2020 and December 31, 2019, FHLBank had rights to collateral on a borrower-by-borrower basis with an estimated value greater than its outstanding advances. FHLBank continues to evaluate and make changes to its collateral guidelines, as necessary, based on current market conditions. As of September 30, 2020 and December 31, 2019, no advances were past due, on non-accrual status, or considered impaired. In addition, there were no troubled debt restructurings related to advances during the three and nine months ended September 30, 2020 and 2019. Allowance for Credit Losses: Conventional Mortgage Loans: Conventional loans are evaluated collectively when similar risk characteristics exists. Conventional loans that do not share risk characteristics with other pools are evaluated for expected credit losses on an individual basis. FHLBank determines its allowances for credit losses on conventional loans through analyses that include consideration of various loan portfolio and collateral-related characteristics, such as past performance, current conditions, and reasonable and supportable forecasts of expected economic conditions. FHLBank uses a model that discounts projected cash flows to estimate expected credit losses over the life of the loans. This model relies on a number of inputs, such as both current and forecasted property values and interest rates as well as historical borrower behavior experience. FHLBank also incorporates associated credit enhancements, as available, to determine its estimate of expected credit losses. Certain conventional loans may be evaluated for credit losses using the practical expedient for collateral dependent assets. A mortgage loan is considered collateral dependent if repayment is expected to be provided by the sale of the underlying property, that is, if it is considered likely that the borrower will default. FHLBank may estimate the fair value of this collateral by applying an appropriate loss severity rate or using third party estimates or property valuation model(s). The expected credit loss of a collateral dependent mortgage loan is equal to the difference between the amortized cost of the loan and the estimated fair value of the collateral, less estimated selling costs. FHLBank records a direct charge-off of the loan balance, if certain triggering criteria are met. Expected recoveries of prior charge-offs, if any, are included in the allowance for credit losses.
New Accounting Pronouncements, Policy	Coronavirus Aid, Relief, and Economic Security Act (CARES Act). In March 2020, the CARES Act was signed into law to provide relief from the economic impact of the COVID-19 pandemic to a variety of sectors of the U.S. economy, including businesses, individuals, health care, education, and state and local governments. The CARES Act also includes provisions that provide optional relief from certain accounting and reporting requirements related to troubled debt restructurings (TDRs). TDR relief applies to COVID-19-related modifications made from March 1, 2020 until the earlier of December 31, 2020 or 60 days following the termination of the national emergency declared by the President of the United States for borrowers that were current as of December 31, 2019. FHLBank has elected the optional relief but does not expect it to have a material effect on FHLBank's financial condition, results of operations, cash flows, or disclosures. Facilitation of the Effects of Reference Rate Reform on Financial Reporting (Accounting Standard Update (ASU) 2020-04) . In March 2020, the Financial Accounting Standards Board (FASB) issued temporary optional guidance to ease the potential burden in accounting for reference rate reform. The new guidance provides optional expedients and exceptions for applying GAAP to transactions affected by reference rate reform if certain criteria are met. The transactions primarily include: (1) contract modifications; (2) hedging relationships; and (3) sale or transfer of debt securities classified as held-to-maturity. This guidance was effective immediately for FHLBank, and the amendments may be applied prospectively through December 31, 2022. FHLBank is in the process of evaluating the guidance, and its effect on FHLBank's financial condition, results of operations and cash flows has not yet been determined. Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract (ASU 2018-15). In August 2018, the FASB issued an amendment to align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). Accordingly, the amendments in this ASU require an entity in a hosting arrangement that is a service contract to follow existing guidance relating to internal-use software to determine which implementation costs to capitalize as an asset related to the service contract and which costs to expense. Costs to develop or obtain internal-use software that cannot be capitalized also cannot be capitalized for a hosting arrangement that is a service contract. Therefore, an entity in a hosting arrangement that is a service contract determines to which project stage (that is, preliminary project stage, application development stage, or post-implementation stage) an implementation activity relates. Costs for implementation activities in the application development stage are capitalized depending on the nature of the costs, while costs incurred during the preliminary project and post-implementation stages are expensed as the activities are performed. The amendments in this ASU also require the entity to expense the capitalized implementation costs of a hosting arrangement that is a service contract over the term of the hosting arrangement. The amendments in this ASU were effective January 1, 2020 for FHLBank. The adoption of this guidance did not materially impact FHLBank's financial condition, results of operations or cash flows. Changes to the Disclosure Requirements for Defined Benefit Plans (ASU 2018-14). In August 2018, the FASB issued an amendment modifying the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans to improve disclosure effectiveness. The amendments in the ASU remove disclosures that are no longer considered cost beneficial, clarify the specific requirements of disclosures, and add disclosure requirements identified as relevant. The amendments in this ASU are effective for annual periods ending after December 15, 2020, which is the year ending December 31, 2020 for FHLBank, and will be applied retrospectively for all comparative periods presented. The adoption of this guidance will not have a material impact on the disclosures related to defined benefit plans and will not impact FHLBank’s financial condition, results of operations or cash flows. Changes to the Disclosure Requirements for Fair Value Measurement (ASU 2018-13). In August 2018, the FASB issued an amendment that modifies the disclosure requirements for fair value measurements. This ASU removes the requirement to disclose: (1) the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy; (2) the policy for timing of transfers between levels; and (3) the valuation processes for Level 3 fair value measurements. The ASU requires disclosure of changes in unrealized gains and losses for the period included in OCI for recurring Level 3 fair value measurements held at the end of the reporting period and the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. The amendments in this ASU were effective January 1, 2020 for FHLBank. The adoption of this guidance did not have an impact on the disclosures related to fair value measurements and did not impact FHLBank’s financial condition, results of operations or cash flows. Measurement of Credit Losses on Financial Instruments, as amended (ASU 2016-13). In June 2016, the FASB issued amended guidance for the accounting of credit losses on financial instruments. The amendments require entities to measure expected credit losses based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. An entity must use judgment in determining the relevant information and estimation methods that are appropriate in its circumstances. Additionally, under the new guidance, a financial asset, or a group of financial assets, measured at amortized cost basis is required to be presented at the net amount expected to be collected. The guidance also requires: ▪ The statement of income to reflect the measurement of credit losses for newly recognized financial assets, as well as the expected increases or decreases of expected credit losses that have taken place during the period; ▪ The entities to determine the allowance for credit losses for purchased financial assets with a more-than-insignificant amount of credit deterioration since origination that are measured at amortized cost basis in a similar manner to other financial assets measured at amortized cost basis. The initial allowance for credit losses is required to be added to the purchase price; ▪ Credit losses relating to available-for-sale debt securities to be recorded through an allowance for credit losses. The amendments limit the allowance for credit losses to the amount by which fair value is below amortized cost; and ▪ Public entities to further disaggregate the current disclosure of credit quality indicators in relation to the amortized cost of financing receivables by the year of origination (i.e., vintage). The guidance became effective for FHLBank on January 1, 2020 and was applied using a modified-retrospective approach, through a cumulative-effect adjustment to retained earnings. Adoption of this guidance did not materially impact FHLBank’s financial condition, results of operations, or cash flows.
Derivatives, Offsetting Fair Value Amounts, Policy [Policy Text Block]	FHLBank presents certain financial instruments, including derivatives, repurchase agreements and securities purchased under agreements to resell, on a net basis by clearing agent by Clearinghouse, or by counterparty, when it has met the netting requirements. For these financial instruments, FHLBank has elected to offset its asset and liability positions, as well as cash collateral received or pledged, including associated accrued interest. FHLBank 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 a bankruptcy, insolvency, or similar proceeding involving the Clearinghouse or clearing agent, or both. Based on this analysis, FHLBank presents a net derivative receivable or payable for all of its transactions through a particular clearing agent with a particular Clearinghouse.
Fair Value Transfer, Policy	FHLBank reviews its fair value hierarchy classifications on a quarterly basis. Changes in the observability of the valuation inputs may result in a reclassification of certain assets or liabilities.
