Accounting Policies [Abstract]
Basis of Presentation	BASIS OF PRESENTATION Basis of Presentation: The accompanying interim financial statements of the Federal Home Loan Bank of Topeka (FHLBank or FHLBank Topeka) 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 the 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. The 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, 2016 . The interim financial statements presented herein should be read in conjunction with the FHLBank’s audited financial statements and notes thereto, which are included in the FHLBank’s annual report on Form 10-K filed with the Securities and Exchange Commission (SEC) on March 9, 2017 (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 : 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, the fair value of derivatives and the allowance for credit losses. 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. Derivatives: All derivatives are recognized on the Statements of Condition at their fair values (including net accrued interest receivable or payable on the derivatives) and are reported as either derivative assets or derivative liabilities, net of cash collateral, including initial and variation margin, and accrued interest received or pledged by clearing agents and/or counterparties. The fair values of derivatives are netted by clearing agent or counterparty when the netting requirements have been met. If these netted amounts are positive, they are classified as an asset and, if negative, they are classified as a liability. Cash flows associated with derivatives are reflected as cash flows from operating activities in the Statements of Cash Flows unless the derivative meets the criteria to be a financing derivative. The FHLBank utilizes two Derivative Clearing Organizations (Clearinghouses) for all cleared derivative transactions, LCH.Clearnet LLC and CME Clearing. Effective January 3, 2017, CME Clearing made certain amendments to its rulebook changing the legal characterization of variation margin payments to be daily settlement payments rather than collateral. Variation margin payments related to LCH.Clearnet LLC contracts continue to be characterized as cash collateral. At both Clearinghouses, initial margin is considered cash collateral.

New Accounting Pronouncements and Changes in Accounting Principles [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 Premium Amortization on Purchased Callable Debt Securities. In March 2017, Financial Accounting Standards Board (FASB) issued an amendment to shorten the amortization period of any premium on callable debt securities to the first call date instead of over the contractual life of the instrument. The amendment does not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. The guidance is intended to reduce diversity in practice in the amortization of premiums and the consideration of how the potential of a security being called is factored into current impairment assessments. The amendment also intends to more closely align the amortization of premiums and discounts to the expectations incorporated into the market pricing of the instrument. The amendment will be effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2018, which is January 1, 2019 for the FHLBank, and early adoption is permitted. This guidance should be applied using a modified retrospective method through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. The adoption of this guidance is not expected to have a material effect on the FHLBank's financial condition, results of operations or cash flows. Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. In March 2017, FASB issued an amendment to improve the presentation of net periodic pension cost and net periodic postretirement benefit cost. The amendment requires that the employer disaggregate the service cost component and the other components of net benefit cost and allow only the service cost component of net benefit cost to be eligible for capitalization. The amendment is intended to provide transparency, consistency, and usefulness to users of financial statements. The amendment will be effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2017, which is January 1, 2018 for the FHLBank, and early adoption is permitted. This guidance should be applied retrospectively for the presentation of the service cost component and the other components of net periodic pension cost and net periodic postretirement benefit cost in the income statement and prospectively, on and after the effective date, for the capitalization of the service cost component of net periodic pension cost and net periodic postretirement benefit in assets. The adoption of this guidance is not expected to have a material effect on the FHLBank's financial condition, results of operations or cash flows. Classification of Certain Cash Receipts and Cash Payments. In August 2016, FASB issued amendments to clarify guidance on the classification of certain cash receipts and payments in the statement of cash flows. This guidance is intended to reduce existing diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. This guidance is effective for the FHLBank for interim and annual periods beginning on January 1, 2018, and early adoption is permitted. This guidance should be applied using a retrospective transition method to each period presented. This guidance is not expected to have a material impact on the FHLBank's statement of cash flows. Measurement of Credit Losses on Financial Instruments. In June 2016, 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 is effective for the FHLBank for interim and annual periods beginning on January 1, 2020. Early application is permitted as of the interim and annual reporting periods beginning after December 15, 2018. The guidance should be applied using a modified-retrospective approach, through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. In addition, entities are required to use a prospective transition approach for debt securities for which an other-than-temporary impairment (OTTI) charge had been recognized before the effective date. The FHLBank is currently evaluating this guidance and has begun its implementation efforts by identifying key interpretive issues that will eventually determine the magnitude of the impact on the FHLBank's financial condition, results of operations and cash flows. Contingent Put and Call Options in Debt Instruments. In March 2016, FASB issued amendments to resolve current diversity in practice by clarifying the steps required when assessing whether the economic characteristics and risks of call (put) options are clearly and closely related to the economic characteristics and risks of their debt hosts, which is one of the criteria for bifurcating an embedded derivative. The amendments apply to all entities that are issuers of or investors in debt instruments (or hybrid financial instruments that are determined to have a debt host) with embedded call (put) options. The amendments became effective for annual periods, and interim periods within those annual periods, beginning on January 1, 2017. The adoption of this guidance had no effect on the FHLBank's financial condition, results of operations or cash flows. Leases. In February 2016, FASB issued amendments to lease accounting guidance. Under the new guidance, lessees will be required to recognize a lease liability and a right-of-use asset for all leases in the statement of financial condition, which effectively removes a source of off-balance sheet financing for operating leases. A distinction remains between finance leases and operating leases, but the assets and liabilities arising from operating leases are now also required to be recognized in the statement of financial condition. Lessor accounting is largely unchanged. The amendments are effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2018, which is January 1, 2019 for the FHLBank. The FHLBank has a limited number of lease agreements and is currently evaluating this guidance to determine the impact, if any, on the FHLBank's financial condition, results of operations or cash flows. Recognition and Measurement of Financial Assets and Financial Liabilities. In January 2016, FASB issued amendments to improve the recognition, measurement, presentation and disclosure of financial instruments through changes to existing GAAP. The provisions impacting the FHLBank include the elimination of the requirement to disclose the method and significant assumptions used to estimate the fair value of financial instruments carried at amortized cost, the requirement to use the notion of exit price when measuring the fair value of financial instruments for disclosure purposes, and the separate presentation of financial assets and financial liabilities by measurement category and form of asset (i.e., securities or loans and receivables) on the statement of financial condition or in the notes to financial statements. The amendments are effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2017, which is January 1, 2018 for the FHLBank. The FHLBank has concluded that this guidance will impact disclosures related to the fair value of financial instruments. However, the FHLBank is currently evaluating these amendments to determine the impact, if any, on the FHLBank's financial condition, results of operations or cash flows. Revenue Recognition. In May 2014, FASB issued guidance to introduce a new revenue recognition model in which an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This guidance also requires disclosures sufficient to enable users to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers, including qualitative and quantitative disclosures about contracts with customers, significant judgments and changes in judgments, and assets recognized from the costs to obtain or fulfill a contract. In July 2015, FASB voted to defer the effective date of the new standard by one year. In addition, in March 2016, FASB issued amendments to clarify the implementation guidance on principal versus agent considerations, in particular, relating to how an entity should determine whether the entity is a principal or an agent for each specified good or service promised to the customer and the nature of each specified good or service. The amendments do not change the core principle in the new revenue standard. The standard is effective for fiscal years, including interim periods within those fiscal years, beginning after December 15, 2017, which is January 1, 2018 for the FHLBank. Because the guidance does not apply to revenue associated with financial instruments, including loans and securities that are accounted for under other GAAP, the FHLBank does not expect the new guidance to have a material impact on its financial condition, results of operations or cash flows.

The discounted cash flows will move from the discounted loss value to the ultimate principal to be written off at the projected date of loss. If the expected cash flows improve, the amount of expected loss decreases which causes a corresponding decrease in the calculated amortization. Based on the level of improvement in the cash flows, the amortization could become a positive adjustment to income. As of March 31, 2017 , the fair value of a portion of the FHLBank's available-for-sale and held-to-maturity MBS were below the amortized cost of the securities due to interest rate volatility and/or illiquidity. However, the decline in fair value of these securities is considered temporary as the FHLBank expects to recover the entire amortized cost basis on the remaining securities in unrecognized loss positions and neither intends to sell these securities nor is it more likely than not that the FHLBank will be required to sell these securities before its anticipated recovery of the remaining amortized cost basis. For state and local housing agency obligations, the FHLBank determined that all of the gross unrealized losses on these bonds were temporary because the strength of the underlying collateral and credit enhancements was sufficient to protect the FHLBank from losses based on current expectations.

Advances [Abstract]
Advances	ADVANCES General Terms: The FHLBank offers a wide range of fixed and variable rate advance products with different maturities, interest rates, payment characteristics and optionality. As of March 31, 2017 and December 31, 2016 , the FHLBank had advances outstanding at interest rates ranging from 0.66 percent to 7.41 percent and 0.46 percent to 7.41 percent , respectively. Table 4.1 presents advances summarized by year of contractual maturity as of March 31, 2017 and December 31, 2016 (dollar amounts in thousands): Table 4.1 03/31/2017 12/31/2016 Year of Contractual Maturity Amount Weighted Average Interest Rate Amount Weighted Average Interest Rate Due in one year or less $ 19,160,922 1.16 % $ 12,601,183 1.03 % Due after one year through two years 1,886,504 1.78 2,019,260 1.96 Due after two years through three years 975,626 1.72 1,073,881 1.47 Due after three years through four years 1,047,470 2.08 781,339 1.96 Due after four years through five years 673,581 2.00 848,112 2.15 Thereafter 2,071,070 2.17 6,636,740 1.19 Total par value 25,815,173 1.37 % 23,960,515 1.24 % Discounts (12,435 ) (13,977 ) Hedging adjustments 20,207 39,297 TOTAL $ 25,822,945 $ 23,985,835 The FHLBank’s advances outstanding 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). The FHLBank’s advances as of March 31, 2017 and December 31, 2016 include callable advances totaling $1,927,022,000 and $6,336,280,000 , respectively. Of these callable advances, there were $1,880,337,000 and $6,260,837,000 of variable rate advances as of March 31, 2017 and December 31, 2016 , respectively. Convertible advances allow the FHLBank to convert an advance from one interest payment term structure to another. When issuing convertible advances, the FHLBank purchases put options from a member that allow the 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. As of March 31, 2017 and December 31, 2016 , the FHLBank had convertible advances outstanding totaling $1,027,342,000 and $1,147,392,000 , respectively.

These mortgage loans are government-insured or guaranteed loans (by the Federal Housing Administration (FHA), the Department of Veterans Affairs (VA), the Rural Housing Service of the Department of Agriculture (RHS) and/or the Department of Housing and Urban Development (HUD)) and conventional residential loans credit-enhanced by participating financial institutions (PFIs) . Depending upon a member’s product selection, the servicing rights can be retained or sold by the participating member. The FHLBank does not buy or own any mortgage servicing rights.

Receivables [Abstract]
Allowance For Credit Losses	ALLOWANCE FOR CREDIT LOSSES The FHLBank has established an allowance methodology for each of its portfolio segments: credit products (advances, letters of credit and other extensions of credit to borrowers); government mortgage loans held for portfolio; conventional mortgage loans held for portfolio; the direct financing lease receivable; term Federal funds sold; and term securities purchased under agreements to resell. Based on management's analyses of each portfolio segment, the FHLBank has only established an allowance for credit losses on its conventional mortgage loans held for portfolio. Roll-forward of Allowance for Credit Losses : Table 6.1 presents a roll-forward of the allowance for credit losses for the three months ended March 31, 2017 as well as the method used to evaluate impairment relating to all portfolio segments regardless of whether or not an estimated credit loss has been recorded as of March 31, 2017 (in thousands). The recorded investment in a financing receivable is the UPB, adjusted for accrued interest, net deferred loan fees or costs, unamortized premiums or discounts, fair value hedging adjustments and direct write-downs. The recorded investment is not net of any valuation allowance.

The recorded investment for all other credit products is insignificant. Credit Quality Indicators: The FHLBank’s key credit quality indicators include the migration of: (1) past due loans; (2) non-accrual loans; (3) loans in process of foreclosure; and (4) impaired loans, all of which are used either on an individual or pool basis to determine the allowance for credit losses. Table 6.3 summarizes the delinquency aging and key credit quality indicators for all of the FHLBank’s portfolio segments as of March 31, 2017 (dollar amounts in thousands): Table 6.3 03/31/2017 Conventional Loans Government Loans Credit Products 1 Direct Financing Lease Receivable Total Recorded investment: Past due 30-59 days delinquent $ 36,450 $ 17,008 $ — $ — $ 53,458 Past due 60-89 days delinquent 7,440 4,534 — — 11,974 Past due 90 days or more delinquent 11,798 5,728 — — 17,526 Total past due 55,688 27,270 — — 82,958 Total current loans 6,013,193 638,524 25,848,675 16,763 32,517,155 Total recorded investment $ 6,068,881 $ 665,794 $ 25,848,675 $ 16,763 $ 32,600,113 Other delinquency statistics: In process of foreclosure, included above 2 $ 4,189 $ 1,676 $ — $ — $ 5,865 Serious delinquency rate 3 0.2 % 0.9 % — % — % 0.1 % Past due 90 days or more and still accruing interest $ — $ 5,728 $ — $ — $ 5,728 Loans on non-accrual status 4 $ 15,323 $ — $ — $ — $ 15,323 1 The recorded investment for credit products includes only advances.

Cash collateral posted was $84,732,000 and $105,481,000 as of March 31, 2017 and December 31, 2016 , respectively. Cash collateral received was $24,776,000 and $21,490,000 as of March 31, 2017 and December 31, 2016 , respectively. Variation margin for daily settled contracts was $(10,292,000) as of March 31, 2017. The following tables provide information regarding gains and losses on derivatives and hedging activities by type of hedge and type of derivative and gains and losses by hedged item for fair value hedges. For the three months ended March 31, 2017 and 2016 , the FHLBank recorded net gain (loss) on derivatives and hedging activities as presented in Table 7.2 (in thousands): Table 7.2 Three Months Ended 03/31/2017 03/31/2016 Derivatives designated as hedging instruments: Interest rate swaps $ (1,330 ) $ (2,490 ) Total net gain (loss) related to fair value hedge ineffectiveness (1,330 ) (2,490 ) Derivatives not designated as hedging instruments: Economic hedges: Interest rate swaps 8,248 (43,208 ) Interest rate caps/floors (1,608 ) (2,093 ) Net interest settlements (5,183 ) (12,244 ) Mortgage delivery commitments 490 1,549 Total net gain (loss) related to derivatives not designated as hedging instruments 1,947 (55,996 ) Other 1 (14 ) — NET GAIN (LOSS) ON DERIVATIVES AND HEDGING ACTIVITIES $ 603 $ (58,486 ) 1 Amount represents price alignment amount on derivatives for which variation margin is characterized as a daily settled contract. The FHLBank carries derivative instruments at fair value on its Statements of Condition. Any change in the fair value of derivatives designated under a fair value hedging relationship is recorded each period in current period earnings. Fair value hedge accounting allows for the offsetting fair value of the hedged risk in the hedged item to also be recorded in current period earnings. For the three months ended March 31, 2017 and 2016 , the FHLBank recorded net gain (loss) on derivatives and the related hedged items in fair value hedging relationships and the impact of those derivatives on the FHLBank’s net interest income as presented in Table 7.3 (in thousands): Table 7.3 Three Months Ended 03/31/2017 03/31/2016 Gain (Loss) on Derivatives Gain (Loss) on Hedged Items Net Fair Value Hedge Ineffectiveness Effect of Derivatives on Net Interest Income 1 Gain (Loss) on Derivatives Gain (Loss) on Hedged Items Net Fair Value Hedge Ineffectiveness Effect of Derivatives on Net Interest Income 1 Advances $ 18,116 $ (18,228 ) $ (112 ) $ (16,491 ) $ (55,659 ) $ 55,225 $ (434 ) $ (25,434 ) Investments 3,266 (3,813 ) (547 ) (2,715 ) (22,815 ) 21,462 (1,353 ) (2,337 ) Consolidated obligation bonds (4,220 ) 3,585 (635 ) 5,519 6,737 (7,153 ) (416 ) 11,547 Consolidated obligation discount notes 16 (52 ) (36 ) (15 ) 84 (371 ) (287 ) (60 ) TOTAL $ 17,178 $ (18,508 ) $ (1,330 ) $ (13,702 ) $ (71,653 ) $ 69,163 $ (2,490 ) $ (16,284 ) 1 The differentials between accruals of interest receivables and payables on derivatives designated as fair value hedges as well as the amortization/accretion of hedging activities are recognized as adjustments to the interest income or expense of the designated underlying hedged item. Based on credit analyses and collateral requirements, FHLBank management does not anticipate any credit losses on its derivative agreements. The maximum credit risk applicable to a single counterparty was $22,816,000 and $21,112,000 as of March 31, 2017 and December 31, 2016 , respectively. The counterparty was the same for both periods . Certain of the FHLBank’s uncleared derivative instruments contain provisions that require the FHLBank to post additional collateral with its counterparties if there is deterioration in the FHLBank’s credit rating. If the FHLBank’s credit rating is lowered by a Nationally Recognized Statistical Rating Organization (NRSRO) , the FHLBank may be required to deliver additional collateral on uncleared derivative instruments in net liability positions. The aggregate fair value of all uncleared derivative instruments with derivative counterparties containing credit-risk-related contingent features that were in a net derivative liability position (before cash collateral and related accrued interest) as of March 31, 2017 and December 31, 2016 was $899,000 and $4,779,000 , respectively, for which the FHLBank has posted no collateral. If the FHLBank’s credit rating had been lowered one level (e.g., from double-A to single-A), the FHLBank would not have been required to deliver additional collateral to its uncleared derivative counterparties as of March 31, 2017 and December 31, 2016 , respectively. The FHLBank utilizes two Clearinghouses for all cleared derivative transactions, LCH.Clearnet LLC and CME Clearing. Effective January 3, 2017, CME Clearing made certain amendments to its rulebook changing the legal characterization of variation margin payments to represent daily settlement payments rather than collateral. Variation margin related to LCH.Clearnet LLC contracts continues to be characterized as cash collateral. 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. The FHLBank was not required to post additional initial margin by its clearing agents as of March 31, 2017 and December 31, 2016 . The FHLBank’s net exposure on derivative agreements is presented in Note 10 .

The 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, the FHLBank also enters into interest rate swap agreements (in which the 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 the FHLBank to obtain attractively priced variable rate financing.

Stockholders' Equity Note [Abstract]
Capital	CAPITAL Capital Requirements: The FHLBank is subject to three capital requirements under the provisions of the Gramm-Leach-Bliley Act (GLB Act) and the Federal Housing Finance Agency's (Finance Agency) capital structure regulation. Regulatory capital does not include AOCI but does include mandatorily redeemable capital stock. • Risk-based capital. The 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 Finance Agency. Only permanent capital, defined as Class B Common Stock and retained earnings, can be used by the FHLBank to satisfy its risk-based capital requirement. The Finance Agency may require the FHLBank to maintain a greater amount of permanent capital than is required by the risk-based capital requirement as defined, but the Finance Agency has not placed any such requirement on the FHLBank to date. • Total regulatory capital. The GLB Act requires the 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 Finance Agency as available to absorb losses. • Leverage capital. The 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 11.1 illustrates that the FHLBank was in compliance with its regulatory capital requirements as of March 31, 2017 and December 31, 2016 (dollar amounts in thousands): Table 11.1 03/31/2017 12/31/2016 Required Actual Required Actual Regulatory capital requirements: Risk-based capital $ 336,896 $ 1,946,691 $ 333,044 $ 1,800,372 Total regulatory capital-to-asset ratio 4.0 % 4.5 % 4.0 % 4.3 % Total regulatory capital $ 1,883,645 $ 2,122,165 $ 1,808,670 $ 1,964,541 Leverage capital ratio 5.0 % 6.6 % 5.0 % 6.3 % Leverage capital $ 2,354,557 $ 3,095,510 $ 2,260,837 $ 2,864,727 Mandatorily Redeemable Capital Stock: The FHLBank is a cooperative whose members and former members own all of the FHLBank’s capital stock. Member shares cannot be purchased or sold except between the 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, the 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 11.2 presents a roll-forward of mandatorily redeemable capital stock for the three months ended March 31, 2017 and 2016 (in thousands): Table 11.2 Three Months Ended 03/31/2017 03/31/2016 Balance, beginning of period $ 2,670 $ 2,739 Capital stock subject to mandatory redemption reclassified from equity during the period 173,395 160,234 Redemption or repurchase of mandatorily redeemable capital stock during the period (173,814 ) (159,546 ) Stock dividend classified as mandatorily redeemable capital stock during the period 13 6 Balance, end of period $ 2,264 $ 3,433 Table 11.3 shows the amount of mandatorily redeemable capital stock by contractual year of redemption as of March 31, 2017 and December 31, 2016 (in thousands). The year of redemption in Table 11.3 is the end of the redemption period in accordance with the FHLBank’s capital plan. The 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 the FHLBank receives notice for withdrawal. Additionally, the 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, the 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 11.3 Contractual Year of Repurchase 03/31/2017 12/31/2016 Year 1 $ 1 $ 192 Year 2 1 1 Year 3 — — Year 4 — — Year 5 543 641 Past contractual redemption date due to remaining activity 1 1,719 1,836 TOTAL $ 2,264 $ 2,670 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. Finance Agency rules limit the ability of the FHLBank to create excess member stock under certain circumstances. For example, the FHLBank may not pay dividends in the form of capital stock or issue new excess stock to members if the FHLBank’s excess stock exceeds one percent of its total assets or if the issuance of excess stock would cause the FHLBank’s excess stock to exceed one percent of its total assets. As of March 31, 2017 , the FHLBank’s excess stock was less than one percent of total assets. Capital Classification Determination: The Finance Agency implemented the prompt corrective action (PCA) provisions of the Housing and Economic Recovery Act of 2008. The rule established four capital classifications (i.e., adequately capitalized, undercapitalized, significantly undercapitalized, and critically undercapitalized) for FHLBanks and implemented the PCA provisions that apply to FHLBanks that are not deemed to be adequately capitalized. The Finance Agency determines each FHLBank’s capital classification on at least a quarterly basis. If an FHLBank is determined to be other than adequately capitalized, the FHLBank becomes subject to additional supervisory authority by the Finance Agency. Before implementing a reclassification, the Director of the Finance Agency is required to provide the FHLBank with written notice of the proposed action and an opportunity to submit a response. As of the most recent review by the Finance Agency for the fourth quarter of 2016 , the FHLBank has been classified as adequately capitalized .

Fair Values

Fair Values	Mar. 31, 2017
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 the FHLBank using available market and other pertinent information and reflect the FHLBank’s best judgment of appropriate valuation methods. Although the 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 March 31, 2017 and December 31, 2016 . 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 FHLBank records trading securities, available-for-sale securities, derivative assets and derivative liabilities at fair value on a recurring basis and on occasion, certain private-label MBS, impaired mortgage loans held for portfolio and non-financial assets on a non-recurring basis. The fair value hierarchy requires the 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. The 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 the FHLBank can access on the measurement date. • Level 2 Inputs – Inputs other than quoted prices within Level 1 that are observable inputs for the asset or liability, either directly or indirectly. If the asset or liability has a specified (contractual) term, a Level 2 input must be observable for substantially the full term of the asset or liability. Level 2 inputs include the following: (1) quoted prices for similar assets 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. The 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 reclassifications of assets or liabilities recorded at fair value on a recurring basis during the three months ended March 31, 2017 and 2016 . The carrying value and fair value of the FHLBank’s financial assets and liabilities as of March 31, 2017 and December 31, 2016 are summarized in Tables 13.1 and 13.2 (in thousands). These values do not represent an estimate of the overall market value of the FHLBank as a going concern, which would take into account future business opportunities and the net profitability of assets and liabilities.

The FHLBank measures certain held-to-maturity securities at fair value on a nonrecurring basis due to the recognition of a credit loss. For held-to-maturity securities that had credit impairment recorded during a period for which no total impairment was recorded (the full amount of additional credit impairment was a reclassification from non-credit impairment previously recorded in AOCI), these securities were recorded at their carrying values and not fair value. The FHLBank measures certain impaired mortgage loans held for portfolio at fair value on a nonrecurring basis when, upon individual evaluation for impairment, the estimated fair value less costs to sell is lower than the recorded investment. REO is measured at fair value when the asset’s fair value less costs to sell is lower than its carrying amount.

The par amounts for which FHLBank Topeka is jointly and severally liable were approximately $915,106,348,000 and $946,829,735,000 as of March 31, 2017 and December 31, 2016 , respectively. Off-balance Sheet Commitments: As of March 31, 2017 and December 31, 2016 , off-balance sheet commitments are presented in Table 14.1 (in thousands): Table 14.1 03/31/2017 12/31/2016 Notional Amount Expire Within One Year Expire After One Year Total Expire Within One Year Expire After One Year Total Standby letters of credit outstanding $ 3,208,195 $ 15,656 $ 3,223,851 $ 2,995,497 $ 12,823 $ 3,008,320 Advance commitments outstanding 80,475 15,000 95,475 37,950 45,025 82,975 Commitments for standby bond purchases 413,922 780,074 1,193,996 210,349 1,002,669 1,213,018 Commitments to fund or purchase mortgage loans 116,453 — 116,453 90,013 — 90,013 Commitments to issue consolidated bonds, at par 72,500 — 72,500 45,000 — 45,000 Commitments to Extend Credit: Standby letters of credit are executed for members for a fee. A standby letter of credit is a short-term financing arrangement between the FHLBank and its member or non-member housing associate. If the FHLBank is required to make payment for a beneficiary’s draw, these amounts are converted into a collateralized advance to the member. As of March 31, 2017 , outstanding standby letters of credit had terms to maturity upon issuance of the currently outstanding standby letters of credit of 4 days to 10 years with a final expiration in 2020 . As of December 31, 2016 , outstanding standby letters of credit had terms to maturity upon issuance of the currently outstanding standby letters of credit of 7 days to 10 years with a final expiration in 2020 . Unearned fees as well as the value of the guarantees related to standby letters of credit are recorded in other liabilities and amounted to $1,061,000 and $1,151,000 as of March 31, 2017 and December 31, 2016 , respectively. Standby letters of credit are fully collateralized with assets allowed by the FHLBank’s Member Products Policy (MPP) . Advance commitments legally bind and unconditionally obligate the 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, the FHLBank does not expect to incur any credit losses on the outstanding letters of credit or advance commitments. Standby Bond-Purchase Agreements: The FHLBank has entered into standby bond purchase agreements with state housing authorities whereby the 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 the FHLBank to purchase the bond. The bond purchase commitments entered into by the FHLBank expire no later than 2020 , though some are renewable at the option of the FHLBank. As of March 31, 2017 and December 31, 2016 , the total commitments for bond purchases were with two in-district and one out-of-district state housing authorities. The FHLBank was not required to purchase any bonds under any agreements during the three months ended March 31, 2017 and 2016 . Commitments to Purchase Mortgage Loans: These commitments that unconditionally obligate the 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. The FHLBank recorded mortgage delivery commitment net derivative asset (liability) balances of $305,000 and $(158,000) as of March 31, 2017 and December 31, 2016 , respectively. Commitments to Issue Consolidated Obligations: The FHLBank enters into commitments to issue consolidated obligation bonds and discount notes outstanding in the normal course of its business. All settle within the shortest period possible and are considered regular way trades; thus, the commitments are appropriately not recorded as derivatives.

Federal Home Loan Banks [Abstract]
Transactions With Stockholders And Housing Associates	TRANSACTIONS WITH STOCKHOLDERS The FHLBank is a cooperative whose members own the capital stock of the 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. The 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 the 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, the FHLBank defines related parties as FHLBank directors’ financial institutions and members with capital stock investments in excess of 10 percent of the FHLBank’s total regulatory capital stock outstanding, which includes mandatorily redeemable capital stock. Activity with Members that Exceed a 10 Percent Ownership in FHLBank Capital Stock: Tables 15.1 and 15.2 present information as of March 31, 2017 and December 31, 2016 on members that owned more than 10 percent of outstanding FHLBank regulatory capital stock in 2017 or 2016 (dollar amounts in thousands). None of the officers or directors of these members currently serve on the FHLBank’s board of directors.

Basis of Presentation (Policy)

Basis of Presentation (Policy)	Mar. 31, 2017
Accounting Policies [Abstract]
Basis of Presentation, Policy	Basis of Presentation: The accompanying interim financial statements of the Federal Home Loan Bank of Topeka (FHLBank or FHLBank Topeka) 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 the 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. The 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, 2016 . The interim financial statements presented herein should be read in conjunction with the FHLBank’s audited financial statements and notes thereto, which are included in the FHLBank’s annual report on Form 10-K filed with the Securities and Exchange Commission (SEC) on March 9, 2017 (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, the fair value of derivatives and the allowance for credit losses. 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.
Derivatives, Policy [Policy Text Block]	Derivatives: All derivatives are recognized on the Statements of Condition at their fair values (including net accrued interest receivable or payable on the derivatives) and are reported as either derivative assets or derivative liabilities, net of cash collateral, including initial and variation margin, and accrued interest received or pledged by clearing agents and/or counterparties. The fair values of derivatives are netted by clearing agent or counterparty when the netting requirements have been met. If these netted amounts are positive, they are classified as an asset and, if negative, they are classified as a liability. Cash flows associated with derivatives are reflected as cash flows from operating activities in the Statements of Cash Flows unless the derivative meets the criteria to be a financing derivative. The FHLBank utilizes two Derivative Clearing Organizations (Clearinghouses) for all cleared derivative transactions, LCH.Clearnet LLC and CME Clearing. Effective January 3, 2017, CME Clearing made certain amendments to its rulebook changing the legal characterization of variation margin payments to be daily settlement payments rather than collateral. Variation margin payments related to LCH.Clearnet LLC contracts continue to be characterized as cash collateral. At both Clearinghouses, initial margin is considered cash collateral.
New Accounting Pronouncements, Policy	Premium Amortization on Purchased Callable Debt Securities. In March 2017, Financial Accounting Standards Board (FASB) issued an amendment to shorten the amortization period of any premium on callable debt securities to the first call date instead of over the contractual life of the instrument. The amendment does not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. The guidance is intended to reduce diversity in practice in the amortization of premiums and the consideration of how the potential of a security being called is factored into current impairment assessments. The amendment also intends to more closely align the amortization of premiums and discounts to the expectations incorporated into the market pricing of the instrument. The amendment will be effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2018, which is January 1, 2019 for the FHLBank, and early adoption is permitted. This guidance should be applied using a modified retrospective method through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. The adoption of this guidance is not expected to have a material effect on the FHLBank's financial condition, results of operations or cash flows. Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. In March 2017, FASB issued an amendment to improve the presentation of net periodic pension cost and net periodic postretirement benefit cost. The amendment requires that the employer disaggregate the service cost component and the other components of net benefit cost and allow only the service cost component of net benefit cost to be eligible for capitalization. The amendment is intended to provide transparency, consistency, and usefulness to users of financial statements. The amendment will be effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2017, which is January 1, 2018 for the FHLBank, and early adoption is permitted. This guidance should be applied retrospectively for the presentation of the service cost component and the other components of net periodic pension cost and net periodic postretirement benefit cost in the income statement and prospectively, on and after the effective date, for the capitalization of the service cost component of net periodic pension cost and net periodic postretirement benefit in assets. The adoption of this guidance is not expected to have a material effect on the FHLBank's financial condition, results of operations or cash flows. Classification of Certain Cash Receipts and Cash Payments. In August 2016, FASB issued amendments to clarify guidance on the classification of certain cash receipts and payments in the statement of cash flows. This guidance is intended to reduce existing diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. This guidance is effective for the FHLBank for interim and annual periods beginning on January 1, 2018, and early adoption is permitted. This guidance should be applied using a retrospective transition method to each period presented. This guidance is not expected to have a material impact on the FHLBank's statement of cash flows. Measurement of Credit Losses on Financial Instruments. In June 2016, 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 is effective for the FHLBank for interim and annual periods beginning on January 1, 2020. Early application is permitted as of the interim and annual reporting periods beginning after December 15, 2018. The guidance should be applied using a modified-retrospective approach, through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. In addition, entities are required to use a prospective transition approach for debt securities for which an other-than-temporary impairment (OTTI) charge had been recognized before the effective date. The FHLBank is currently evaluating this guidance and has begun its implementation efforts by identifying key interpretive issues that will eventually determine the magnitude of the impact on the FHLBank's financial condition, results of operations and cash flows. Contingent Put and Call Options in Debt Instruments. In March 2016, FASB issued amendments to resolve current diversity in practice by clarifying the steps required when assessing whether the economic characteristics and risks of call (put) options are clearly and closely related to the economic characteristics and risks of their debt hosts, which is one of the criteria for bifurcating an embedded derivative. The amendments apply to all entities that are issuers of or investors in debt instruments (or hybrid financial instruments that are determined to have a debt host) with embedded call (put) options. The amendments became effective for annual periods, and interim periods within those annual periods, beginning on January 1, 2017. The adoption of this guidance had no effect on the FHLBank's financial condition, results of operations or cash flows. Leases. In February 2016, FASB issued amendments to lease accounting guidance. Under the new guidance, lessees will be required to recognize a lease liability and a right-of-use asset for all leases in the statement of financial condition, which effectively removes a source of off-balance sheet financing for operating leases. A distinction remains between finance leases and operating leases, but the assets and liabilities arising from operating leases are now also required to be recognized in the statement of financial condition. Lessor accounting is largely unchanged. The amendments are effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2018, which is January 1, 2019 for the FHLBank. The FHLBank has a limited number of lease agreements and is currently evaluating this guidance to determine the impact, if any, on the FHLBank's financial condition, results of operations or cash flows. Recognition and Measurement of Financial Assets and Financial Liabilities. In January 2016, FASB issued amendments to improve the recognition, measurement, presentation and disclosure of financial instruments through changes to existing GAAP. The provisions impacting the FHLBank include the elimination of the requirement to disclose the method and significant assumptions used to estimate the fair value of financial instruments carried at amortized cost, the requirement to use the notion of exit price when measuring the fair value of financial instruments for disclosure purposes, and the separate presentation of financial assets and financial liabilities by measurement category and form of asset (i.e., securities or loans and receivables) on the statement of financial condition or in the notes to financial statements. The amendments are effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2017, which is January 1, 2018 for the FHLBank. The FHLBank has concluded that this guidance will impact disclosures related to the fair value of financial instruments. However, the FHLBank is currently evaluating these amendments to determine the impact, if any, on the FHLBank's financial condition, results of operations or cash flows. Revenue Recognition. In May 2014, FASB issued guidance to introduce a new revenue recognition model in which an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This guidance also requires disclosures sufficient to enable users to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers, including qualitative and quantitative disclosures about contracts with customers, significant judgments and changes in judgments, and assets recognized from the costs to obtain or fulfill a contract. In July 2015, FASB voted to defer the effective date of the new standard by one year. In addition, in March 2016, FASB issued amendments to clarify the implementation guidance on principal versus agent considerations, in particular, relating to how an entity should determine whether the entity is a principal or an agent for each specified good or service promised to the customer and the nature of each specified good or service. The amendments do not change the core principle in the new revenue standard. The standard is effective for fiscal years, including interim periods within those fiscal years, beginning after December 15, 2017, which is January 1, 2018 for the FHLBank. Because the guidance does not apply to revenue associated with financial instruments, including loans and securities that are accounted for under other GAAP, the FHLBank does not expect the new guidance to have a material impact on its financial condition, results of operations or cash flows.
Finance, Loan and Lease Receivables, Held-for-investment, Allowance and Nonperforming Loans, Allowance Policy	The FHLBank has established an allowance methodology for each of its portfolio segments: credit products (advances, letters of credit and other extensions of credit to borrowers); government mortgage loans held for portfolio; conventional mortgage loans held for portfolio; the direct financing lease receivable; term Federal funds sold; and term securities purchased under agreements to resell. Based on management's analyses of each portfolio segment, the FHLBank has only established an allowance for credit losses on its conventional mortgage loans held for portfolio.
Fair Value Transfer, Policy	The 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.

The discounted cash flows will move from the discounted loss value to the ultimate principal to be written off at the projected date of loss. If the expected cash flows improve, the amount of expected loss decreases which causes a corresponding decrease in the calculated amortization. Based on the level of improvement in the cash flows, the amortization could become a positive adjustment to income.

Hierarchy Level for Financial Assets and Liabilities - Recurring and Nonrecurring	Tables 13.3 and 13.4 present, for each hierarchy level, the FHLBank’s assets and liabilities that are measured at fair value on a recurring or nonrecurring basis on the Statements of Condition as of or for the periods ended March 31, 2017 and December 31, 2016 (in thousands). The FHLBank measures certain held-to-maturity securities at fair value on a nonrecurring basis due to the recognition of a credit loss. For held-to-maturity securities that had credit impairment recorded during a period for which no total impairment was recorded (the full amount of additional credit impairment was a reclassification from non-credit impairment previously recorded in AOCI), these securities were recorded at their carrying values and not fair value. The FHLBank measures certain impaired mortgage loans held for portfolio at fair value on a nonrecurring basis when, upon individual evaluation for impairment, the estimated fair value less costs to sell is lower than the recorded investment. REO is measured at fair value when the asset’s fair value less costs to sell is lower than its carrying amount.

[2]	The FHLBank amortizes the credit component based on estimated cash flows prospectively up to the amount of expected principal to be recovered. The discounted cash flows will move from the discounted loss value to the ultimate principal to be written off at the projected date of loss. If the expected cash flows improve, the amount of expected loss decreases which causes a corresponding decrease in the calculated amortization. Based on the level of improvement in the cash flows, the amortization could become a positive adjustment to income.
