Accounting Policies [Abstract]
Summary of Significant Accounting Policies	These Notes to Financial Statements should be read in conjunction with the Statements of Condition as of December 31, 2021 and 2020, and the Statements of Income, Comprehensive Income, Capital, and Cash Flows for the years ended December 31, 2021, 2020, and 2019. Acronyms and terms used throughout these Notes to Financial Statements are defined herein or in the Defined Terms . Unless the context otherwise requires, the terms "Bank," "we," "us," and "our" refer to the Federal Home Loan Bank of Indianapolis or its management. Background Information The Federal Home Loan Bank of Indianapolis, a federally chartered corporation, is one of 11 regional wholesale FHLBanks in the United States. The FHLBanks are GSEs that were organized under the Bank Act to serve the public by enhancing the availability of credit for residential mortgages and targeted community development. Even though the Bank is part of the FHLBank System, we operate as a separate entity with our own management, employees and board of directors. Each FHLBank is a financial cooperative that provides a readily available, competitively-priced source of funds to its member institutions. Regulated financial depositories and non-captive insurance companies engaged in residential housing finance that have their principal place of business located in, or are domiciled in, our district states of Michigan or Indiana are eligible for membership. Additionally, qualified CDFIs are eligible to be members. Housing Associates, including state and local housing authorities, that meet certain statutory and regulatory criteria may also borrow from us. While eligible to borrow, Housing Associates are not members and, as such, are not allowed to hold our capital stock. Each member must purchase a minimum amount of our capital stock based on the amount of its total assets. A member may be required to purchase additional activity-based capital stock as it engages in certain business activities with us. Members and former members own all of our capital stock. Former members (including certain non-member institutions that own our capital stock as a result of a merger with or acquisition of a member) hold our capital stock solely to support credit products or mortgage loans still outstanding on our statement of condition. All owners of our capital stock, to the extent declared by our board of directors, receive dividends on their capital stock, subject to applicable regulations. The FHLBanks' Office of Finance facilitates the issuance and servicing of the debt instruments of the FHLBanks, known as consolidated obligations, consisting of bonds and discount notes, and prepares and publishes the FHLBanks' combined quarterly and annual financial reports. Proceeds from the issuance of consolidated obligations are the primary source of funds for the FHLBanks. Deposits, other borrowings and capital stock issued to members provide additional funds. We primarily use these funds to: • disburse advances to members; • acquire mortgage loans from PFIs through our MPP; • maintain liquidity; and • invest in other opportunities to support the residential housing market. We also provide correspondent services, such as wire transfer, security safekeeping, and settlement services, to our members. The Finance Agency is the independent federal regulator of the FHLBanks, Freddie Mac, and Fannie Mae. The Finance Agency's stated mission is to ensure that the housing GSEs operate in a safe and sound manner so that they serve as a reliable source of liquidity and funding for housing finance and community investment. Note 1 - Summary of Significant Accounting Policies Basis of Presentation. The accompanying financial statements have been prepared in accordance with GAAP and SEC requirements. The financial statements contain all adjustments that are, in the opinion of management, necessary for a fair statement of the Bank's financial position, results of operations and cash flows for the periods presented. All such adjustments were of a normal recurring nature. Use of Estimates. When preparing financial statements in accordance with GAAP, we are required to make subjective assumptions and estimates that may affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities, and the reported amounts of income and expense. Although the reported amounts and disclosures reflect our best estimates, actual results could differ significantly from these estimates. The most significant estimates pertain to the fair values of financial instruments. Estimated Fair Value. The estimated fair value amounts, recorded on the statement of condition and presented in the accompanying disclosures, reflect appropriate valuation methods and have been determined based on the assumptions that we believe market participants would use in pricing the asset or liability. Although we use our best judgment in estimating fair value, there are inherent limitations in any valuation technique. Therefore, these estimated fair values may not be indicative of the amounts that would have been realized in market transactions on the reporting dates. For more information, see Note 16 - Estimated Fair Values . Reclassifications. We have reclassified certain amounts reported in prior periods to conform to the current period presentation. These reclassifications had no effect on total assets, total liabilities, total capital, net income, total comprehensive income or net cash flows. Interest-Bearing Deposits, Securities Purchased under Agreements to Resell, and Federal Funds Sold. These investments provide short-term liquidity and are carried at cost. Securities purchased under agreements to resell are treated as short-term, collateralized financings. These securities are held in safekeeping in the Bank's name by third-party custodians approved by us. If the market value of the underlying assets declines below the market value required as collateral, the counterparty must (i) place an equivalent amount of additional securities in safekeeping in the Bank's name, and/or (ii) remit an equivalent amount of cash. Federal funds sold are short-term, unsecured loans that are generally transacted on an overnight term. Finance Agency regulations include a limit on the amount of unsecured credit an individual FHLBank may extend to a counterparty. Investment Securities. Purchases and sales of securities are recorded on a trade date basis. We classify investments as trading, HTM or AFS at the date of acquisition. Trading Securities. Securities classified as trading are held for liquidity purposes and carried at fair value. We record changes in the fair value of these securities through other income as net gains (losses) on trading securities. Finance Agency regulation and our risk management policies prohibit the speculative use of these instruments and limit the credit risk arising from these securities. HTM Securities. Securities for which we have both the positive intent and ability to hold to maturity are classified as HTM. The carrying value includes adjustments made to the cost basis of the security for purchase discount and related accretion, purchase premium and related amortization, and collection of principal. Certain changes in circumstances may cause us to change our intent to hold a particular security to maturity without necessarily calling into question our intent to hold other debt securities to maturity. Thus, the sale or transfer of an HTM security due to certain changes in circumstances, such as evidence of significant deterioration in the issuer's creditworthiness or changes in regulatory requirements, is not considered to be inconsistent with its original classification. Other events may also cause us to sell or transfer an HTM security without necessarily calling into question our intent to hold other debt securities to maturity, but such events must be isolated, non-recurring, unusual, and could not have been reasonably anticipated. Sales of HTM debt securities that meet either of the following two conditions may be considered as maturities for purposes of the classification of securities: (i) the sale occurs near enough to its maturity date (or call date, if exercise of the call is probable) that interest-rate risk is substantially eliminated as a pricing factor and any changes in market interest rates would not have a significant effect on the security's fair value, or (ii) the sale occurs after we have already collected a substantial portion (at least 85%) of the principal outstanding at acquisition due either to prepayments or to scheduled payments payable in equal installments (both principal and interest) over its term. AFS Securities. Securities that are not classified as trading or HTM are classified as AFS and carried at estimated fair value. We record changes in the fair value of these securities in OCI as net change in unrealized gains (losses) on AFS securities, except for AFS securities in hedging relationships that qualify as fair-value hedges. For those securities, we record the portion of the change in fair value attributable to the risk being hedged in interest income together with the related change in the fair value of the derivative, and record the remainder of the change in the fair value in OCI as net change in unrealized gains (losses) on AFS securities. Amortization of Purchase Premiums and Discounts. Since we hold a large number of similar loans underlying our MBS, for which prepayments are probable and the timing and amount of prepayments can be reasonably estimated, we amortize or accrete premiums, discounts, and cumulative fair-value hedging basis adjustments on MBS to interest income using a level-yield under the retrospective interest method. This method requires that we estimate prepayments over the estimated life of each security and retrospectively adjust the effective yield each time the estimated remaining cash flows change as if the new estimate had been used since the original acquisition date. Changes in interest rates are a significant assumption used in estimating the timing and amount of prepayments. For all non-MBS securities, we amortize or accrete premiums, discounts, and cumulative fair-value hedging basis adjustments using a level-yield methodology over the contractual life of each security, with the exception of our callable non-MBS securities, on which the purchase premium is amortized to the next call date. For all non-MBS securities, prepayments are not estimated but only taken into account as they actually occur. Gains and Losses on Sales. We compute gains and losses on sales of investment securities using the specific identification method and include these gains and losses in other income as net realized gains (losses) from sale of securities. Advances. We record advances at amortized cost, adjusted to include deferred swap termination fees associated with modified advances, net of deferred prepayment fees, and cumulative fair-value hedging basis adjustments. We amortize such fees and hedging basis adjustments t o interest income using a level-yield methodology over the contractual life of the advance. When an advance is prepaid, we amortize to interest income a proportionate share of the remaining balance of those adjustments. Prepayment Fees. We charge a prepayment fee when a borrower repays certain advances prior to maturity. We report prepayment fees, net of any associated swap termination fees and cumulative fair-value hedging basis adjustments, in interest income on advances. Advance Modifications. When we fund a new advance concurrent with, or within a short period of time after, the prepayment of an original advance, we determine whether the transaction is effectively either (i) two separate transactions (the prepayment of the original advance and the disbursement of a new advance), defined as an advance extinguishment, or (ii) the continuation of the original advance as modified, defined as an advance modification. We account for the transaction as an extinguishment if both of the following criteria are met: (i) the effective yield of the new advance is at least equal to the effective yield for a comparable advance to a member with similar collection risks who is not prepaying, and (ii) modifications of the original advance are determined to be more than minor, i.e., if the present value of the cash flows under the terms of the new advance is at least 10% different from the present value of the remaining cash flows under the original advance or through an evaluation of qualitative factors, which may include changes in the interest-rate exposure to the member by moving from a fixed to an adjustable-rate advance. In all other instances, the transaction is accounted for as an advance modification. If the transaction is determined to be an advance extinguishment, we recognize income from nonrefundable prepayment fees, net of associated swap termination fees, in the period that the extinguishment occurs. Alternatively, if no prepayment fees are received (e.g., the member requests that we embed the prepayment fee into the rate of the new advance), the excess of the present value of the cash flows of the new advance over those of an advance with a current market rate and otherwise comparable terms is immediately recognized in income, and the basis of the new advance is adjusted accordingly. If the transaction is determined to be an advance modification, the nonrefundable prepayment fees, net of associated swap termination fees, are not immediately recognized in income but are (i) included in the carrying value of the modified advance and amortized into interest income over the life of the new advance using a level-yield methodology or (ii) embedded into the rate of the modified advance and recorded as an adjustment to the interest accrual. Mortgage Loans Held for Portfolio. We classify mortgage loans, for which we have the positive intent and ability to hold for the foreseeable future or until maturity or payoff, as held for portfolio. Accordingly, these mortgage loans are reported at cost, adjusted to include premiums paid to and discounts received from PFIs, hedging basis adjustments, and the allowance for credit losses. Amortization of Purchase Premiums and Discounts. We amortize or accrete premiums and discounts and hedging basis adjustments to interest income using a level-yield methodology over the contractual life of each loan. When a loan is prepaid, we amortize to interest income a proportionate share of the remaining balance of those adjustments. Non-accrual Loans. We place a conventional mortgage loan on non-accrual status if it is determined that either (i) the collection of interest or principal is doubtful, or (ii) interest or principal is past due for 90 days or more, except when the loan is well secured and in the process of collection (e.g., through credit enhancements and monthly servicer remittances on a scheduled/scheduled basis). On loans with remittances on a scheduled/scheduled basis, we receive monthly principal and interest payments from the servicer regardless of whether the borrower has made payments to the servicer. Monthly servicer remittances on loans on an actual/actual basis may also be well secured; however, servicers on actual/actual remittance do not advance principal and interest due, regardless of borrower creditworthiness, until the payments are received from the borrower or when the loan is repaid. As a result, these loans are placed on non-accrual status once they become 90 days delinquent. A government-guaranteed or -insured mortgage loan is not placed on non-accrual status when the collection of the contractual principal or interest is 90 days or more past due because of the contractual obligation of the loan servicer to pay defaulted interest at the contractual rate. For those mortgage loans placed on non-accrual status, accrued but uncollected interest is reversed against interest income (for any interest accrued in the current year) and/or the allowance for credit losses (for any interest accrued in the previous year). We record payments received on non-accrual loans as a direct reduction of the amortized cost of the loan. When the amortized cost has been fully collected, any additional amounts collected are recognized as interest income. A loan on non-accrual status may be restored to accrual status when it becomes current (zero days past due) and three consecutive and timely monthly payments have been received. Loan Participations. We may sell participating interests in MPP loans acquired from our PFIs to other FHLBanks. The terms of the sale of these participating interests meet the accounting requirements for a sale and, therefore, the participating interests are derecognized from our reported mortgage loan balances and a pro-rata portion of the fixed LRA is assumed by the participating FHLBank for its use in loss mitigation. As a result, available funds remaining in our LRA are limited to our pro-rata portion of the fixed LRA that is associated with the participating interests retained by us. The portion of the participation fees received related to our upfront costs is recognized immediately into income, while the remaining portion related to our ongoing costs is deferred and amortized to income over the remaining life of the participated loans. Troubled Debt Restructuring. A TDR related to MPP loans typically occurs when a concession is granted to a borrower for economic or legal reasons related to the borrower's financial difficulties that would not have been otherwise considered. Although we do not participate in government-sponsored loan modification programs, we do consider certain conventional loan modifications to be TDRs when the modification agreement permits the recapitalization of past due amounts, generally up to the original loan amount. If a borrower is having financial difficulty and a significant concession has been granted by the PFI with our approval, the loan modification is considered a TDR. No other terms of the original loan are modified, except for the possible extension of the contractual maturity date on a case-by-case basis. In no event does the borrower's original interest rate change. As a result of temporary accounting guidance that remained in effect throughout 2021, we continued excluding all qualifying COVID-19-related loan modifications considered to be formal, i.e. the legal terms of the loan were changed, from TDR classification and accounting. We do not consider any short-term, informal, i.e. the legal terms of the loan have not changed, modifications or payment deferrals alone to be a TDR and thus we continue to follow our existing past-due, non-accrual, TDR and charge-off accounting policies for such loan modifications. Modifications of government loans are not considered or accounted for as TDRs because we anticipate no loss of principal or interest accrued at the original contract rate, or significant delay, due to the government guarantee or insurance. Charge-Offs. A charge-off is recorded to the extent that the amortized cost (including UPB, unamortized premiums or discounts, and hedging basis adjustments) in a loan will not be fully recovered. We record a charge-off on a conventional mortgage loan against the credit loss allowance upon the occurrence of a confirming event. Confirming events include, but are not limited to, the settlement of a claim against any of the credit enhancements, delinquency in excess of 180 days unless we can clearly document that the delinquent loan is well-secured and in-process of collection, and filing for bankruptcy protection. We charge off the portion of the outstanding conventional mortgage loan balance in excess of the fair value of the underlying property, less costs to sell and adjusted for any available credit enhancements. Allowance for Credit Losses on Financial Instruments. As a result of adopting new accounting guidance on January 1, 2020, our financial instruments, i.e. interest-bearing deposits, securities purchased under agreements to resell, federal funds sold, investment securities, advances (including off-balance sheet credit exposures), and mortgage loans held for portfolio, are evaluated quarterly for expected credit losses. If necessary, an allowance for credit losses is recorded with a corresponding adjustment to the provision for credit losses. The allowance for credit losses excludes uncollectible accrued interest receivable for all instruments, which is measured separately. If necessary, we write-off uncollectible accrued interest with a reversal of interest income. Prior to January 1, 2020, we recorded an allowance for credit losses (or OTTI on investment securities) if it was probable that a loss had been incurred as of the statement of condition date and the amount of loss could be reasonably estimated. In addition, our allowance for credit losses on our mortgage loans was based on a loss emergence period of 24 months. For more information on the allowance methodology related to our financial instruments, see Note 4 - Investments, Note 5 - Advances, Note 6 - Mortgage Loans Held for Portfolio, and Note 17 - Commitments and Contingencies. Derivatives and Hedging Activities. We record derivative instruments, related cash collateral (including initial margin received or pledged/posted), variation margin received or pledged/posted, and associated accrued interest on a net basis, by clearing agent and/or by counterparty, as either derivative assets or derivative liabilities at their estimated fair values. Changes in the estimated fair value of derivatives are recorded in current period earnings. Designations. Derivatives are recorded beginning on the trade date and typically executed and designated in a qualifying hedging relationship at the same time as the acquisition of the hedged item. We may also designate the hedging relationship upon the Bank's commitment to disburse an advance, purchase financial instruments, or trade a consolidated obligation in which settlement occurs within the shortest period of time possible for the type of instrument based on market settlement conventions. Each derivative is designated as one of the following: (i) a qualifying hedge of the change in fair value of a recognized asset or liability (e.g., advances, AFS investments, and CO bonds) or an unrecognized firm commitment (fair-value hedge); or (ii) a non-qualifying hedge for asset/liability management purposes (economic hedge). In all cases involving a fair-value hedge of a recognized asset, liability or firm commitment, the designated risk being hedged is the risk of changes in the fair value of the hedged item attributable to changes in the designated benchmark interest rate. Accounting for Qualifying Hedges. Hedging relationships must meet certain criteria including, but not limited to, formal documentation of the hedging relationship and an expectation to be highly effective to qualify for hedge accounting. Two approaches to account for qualifying fair-value hedge relationships include: (i) Shortcut hedge accounting - Transactions that meet certain criteria qualify for the shortcut method of hedge accounting. Under the shortcut method, an assumption can be made that the entire change in fair value of a hedged item, due to changes in the benchmark rate, equates to the entire change in fair value of the related derivative. As a result, the derivative is considered to be perfectly effective in achieving offsetting changes in the fair value of the hedged asset or liability attributable to the hedged risk. When applying the shortcut method, we document, at inception of the hedge relationship, a quantitative long-haul method that we can apply should we subsequently determine a derivative relationship no longer qualifies for shortcut hedge accounting; or (ii) Long-haul hedge accounting - T he application of long-haul hedge accounting requires us to assess whether the derivatives used in hedging transactions are highly effective in offsetting changes in the fair value of hedged items or forecasted transactions attributable to the hedged risk and whether those derivatives may be expected to remain highly effective in future periods. As part of the assessment, a regression analysis is performed at the inception of each hedging relationship and at each month-end thereafter to ensure the hedge relationship has been highly effective historically and is expected to be highly effective in the future. While a number of long-haul methods and techniques are permissible, we utilize the following: • Total Contractual Coupon Method - In calculating the change in the fair value of the hedged item attributable to changes in the benchmark interest rate, the estimated coupon cash flows are based on the full contractual coupon cash flows. • Benchmark Component Method - In calculating the change in fair value of the hedged item attributable to changes in the benchmark interest rate, the credit and any other risks embedded in the contractual coupon rate are excluded from the estimated coupon cash flows by aligning the interest component of the swap with the hedged item. Given this alignment, the application of the benchmark component method generally results in less hedge ineffectiveness in comparison to the total contractual coupon method. Changes in the fair value of a derivative that is designated and qualifies as a fair-value hedge, along with changes in the fair value of the hedged asset or liability that are attributable to the hedged risk, are recorded in net interest income in the same line as the earnings effect of the hedged item. Accounting for Non-Qualifying Hedges. An economic hedge is defined as a derivative that hedges specific or non-specific underlying assets, liabilities, or firm commitments and does not qualify, or was not designated, for hedge accounting. As a result, we recognize only the net interest settlements and the change in fair value of these derivatives in other income as net gains (losses) on derivatives with no offsetting fair-value adjustments in earnings for the hedged assets, liabilities, or firm commitments. An economic hedge by definition, therefore, introduces the potential for earnings variability. Accrued Interest Receivables and Payables. The difference between the interest receivable and payable on a derivative designated as a qualifying hedge is recognized as an adjustment to the income or expense of the designated hedged item. The difference between the interest receivable and payable on economic hedges are recognized in other income as net gains (losses) on derivatives. Discontinuance of Hedge Accounting. We discontinue hedge accounting prospectively when: (i) the hedging relationship ceases to be highly effective; (ii) the derivative and/or the hedged item expires or is sold, terminated, or exercised; (iii) a hedged firm commitment no longer meets the definition of a firm commitment; or (iv) we elect to discontinue hedge accounting. When hedge accounting is discontinued and the derivative and hedged item remain, we: (i) continue to carry the derivative on the statement of condition at fair value as an economic hedge; (ii) cease adjusting the hedged asset or liability for changes in fair value; and (iii) amortize the cumulative basis adjustment on the hedged item into interest income over the remaining life of the hedged item using a level-yield methodology. When we discontinue a qualifying hedge relationship by terminating the derivative and subsequently designating the associated hedged item into a new qualifying hedge relationship, we: (i) recognize the cumulative gain (loss) on the derivative in current earnings; (ii) pay or receive a termination fee with the counterparty, substantially offsetting the recognized gain (loss) on the derivative; (iii) cease adjusting the hedged asset or liability for changes in fair value; and (iv) amortize the cumulative basis adjustment on the hedged item into interest income over the remaining life of the hedged item using a level-yield methodology. Embedded Derivatives. We may issue consolidated obligations, disburse advances, or purchase financial instruments in which a derivative instrument is embedded. In order to determine whether an embedded derivative must be bifurcated from the host instrument and separately valued, we must assess, upon execution of the transaction, whether the economic characteristics of the embedded derivative are clearly and closely related to the economic characteristics of the remaining component of the consolidated obligation, advance or purchased financial instrument (the host contract) and whether a separate, non-embedded instrument with the same terms as the embedded instrument would meet the definition of a derivative instrument. If we determine that (i) the embedded derivative has economic characteristics that are not clearly and closely related to the economic characteristics of the host contract and (ii) a separate, stand-alone instrument with the same terms would qualify as a derivative instrument, the embedded derivative is separated from the host contract, carried at fair value, and designated as a stand-alone derivative instrument pursuant to an economic hedge, and the host contract is accounted for based on the guidance applicable to instruments of that type that are not hedged. However, if (i) the entire contract (the host contract and the embedded derivative) is required to be measured at fair value, with changes in fair value reported in earnings (such as an investment security classified as trading), or (ii) we cannot reliably identify and measure the embedded derivative for purposes of separating that derivative from its host contract, the entire contract is carried at fair value, and no portion of the contract is designated as a hedging instrument. Financial Instruments Meeting Netting Requirements . We present certain financial instruments, including our derivative asset and liability positions as well as cash collateral received or pledged, on a net basis when we have a legal right of offset and all other requirements for netting are met (collectively referred to as the netting requirements). The net exposure for these financial instruments can change on a daily basis; therefore, there may be a delay between the time a change in the exposure is identified and additional collateral is requested, and the time the additional collateral is received or pledged. Likewise, there may be a delay before excess collateral is returned. For derivative instruments that meet the netting requirements, any excess cash collateral received or pledged is recognized as a derivative liability or derivative asset, respectively. For derivative instruments that do not meet the netting requirements, cash collateral is recognized as an interest-bearing asset or liability, as appropriate. Additional information regarding these transactions is provided in Note 8 - Derivatives and Hedging Activities. Premises, Software, and Equipment. We record premises, software, and equipment at cost, less accumulated depreciation and am ortization, in other assets, and compute depreciation and amortization using the straight-line method over their respective estimated useful lives, which range from 3 to 40 years. W e capitalize improvements and major renewals, but expense maintenance and repairs when incurred. We depreciate building improvements using the straight-line method over the estimated useful life of the improvement. In addition, we capitalize software development costs for internal use software with an estimated economic useful life of at least one year. If capitalized, we use the straight-line method for computing amortization. We include any gain or loss on disposal (other than abandonment) of premises, software, and equipment in other income. Any loss on abandonment is included in other operating expenses. Consolidated Obligations. Consolidated obligations are recorded at amortized cost, adjusted to include concessions, discounts, premiums, principal payments, and cumulative fair-value hedging basis adjustments. Discounts and Premiums. We accrete or amortize the discounts and premiums as well as cumulative fair-value hedging basis adjustments to interest expense using a level-yield methodology over the term to contractual maturity of the corresponding CO bond. When we prepay a CO bond, a proportionate share of the remaining balance of those adjustments is recognized as interest income. Concessions. Concessions are paid to dealers in connection with the issuance of certain consolidated obligations. The Office of Finance prorates the amount of our concession

Investments, Debt and Equity Securities [Abstract]
Investments	Note 4 - Investments Short-term Investments. We invest 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 maintain a credit rating of triple-B or higher (investment grade) by an NRSR O. At December 31, 2021 and 2020, none of these investments were with counterparties rated below single-A and none were with unrated counterparties. The N RSRO ratings may differ from our internal ratings of the investments, if applicable. Allowance for Credit Losses. Interest-Bearing Deposits . Interest-bearing deposits are considered overnight investments given our ability to withdraw funds from these accounts at any ti me. As such, no allowance for credit losses was recorded for these investments at December 31, 2021 and 2020. Securities Purchased Under Agreements to Resell. We use the collateral maintenance provision practical expedient for securities purchased under agreements to resell whereby a credit loss is recognized only if there is a collateral shortfall which we do not believe the counterparty is willing or able to replenish in accordance with the contractual terms. The credit loss would be limited to the difference between the estimated fair value of the collateral and the investment’s amortized cost. Based upon the collateral held as security and collateral maintenance provisions with our counterparties, no allowance for credit losses was recorded for securities purchased under agreements to resell at December 31, 2021 and 2020. Federal Funds Sold . As our investments in federal funds sold are typically transacted on an overnight term, we would only evaluate these instruments for expected credit losses if they were not repaid according to their contractual terms at maturity. At December 31, 2021 and 2020, all investments in federal funds sold were repaid according to their contractual terms and, therefore, no allowance for credit losses was recorded.

Contractual Maturity. The amortized cost and estimated fair value of non-MBS AFS securities are presented below by contractual maturity. MBS are not presented by contractual maturity because their actual maturities will likely differ from their contractual maturities as borrowers have the right to prepay their obligations with or without prepayment fees.

At December 31, 2021 and 2020 , 100% of our AFS securities were rated single-A, or above, by an NRSRO, based on the lowest long-term credit rating for each security. These may differ for any internal ratings of the securities, if applicable. We individually evaluate our AFS securities for impairment. Impairment exists when the estimated 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, we consider whether there could be a shortfall in receiving all cash flows that are contractually due. In those instances where we determine a shortfall could exist, we compare the present value of cash flows to be collected from the security to its amortized cost. If the present value of cash flows is less than amortized cost, an allowance for credit losses is recorded, but the allowance is limited to the amount of the unrealized loss. If we do not intend to sell an impaired AFS security and it is not more likely than not that we will be required to sell the security before recovery of its amortized cost basis, after recording the allowance for credit losses, any difference between the security’s estimated fair value and amortized cost remaining is recorded to net unrealized gains (losses) on AFS securities within OCI. If we intend to sell an impaired AFS security, or more likely than not will be required to sell the security before recovery of its amortized cost basis, any allowance for credit losses is reversed and the amortized cost basis is written down to the security’s estimated fair value at the reporting date with any such impairment reported in earnings as net gains (losses) on investment securities. At December 31, 2021 and 2020, certain of our AFS securities were in an unrealized loss position; however, we did not record an allowance for credit losses because those losses were considered temporary and we expected to recover the entire amortized cost basis on these securities at maturity based upon the following factors: (i) all securities were highly-rated, (ii) we have not experienced, nor do we expect, any payment defaults on the securities, (iii) the U.S., GSE, and other Agency obligations carry an explicit or implicit government guarantee such that we consider the risk of nonpayment to be zero, and (iv) we had no intention of selling any of these securities nor did we consider it more likely than not that we will be required to sell any of these securities before recovery of each security's remaining amortized cost basis. Held-to-Maturity Securities. Major Security Types. The following table presents our HTM securities by type of security. Gross Gross Unrecognized Unrecognized Estimated Amortized Holding Holding Fair December 31, 2021 Cost (1) Gains Losses Value MBS: Other U.S. obligations single-family MBS $ 2,626,143 $ 7,384 $ (9,238) $ 2,624,289 GSE single-family MBS 815,924 14,424 (4,773) 825,575 GSE multifamily MBS 871,706 779 (192) 872,293 Total HTM securities $ 4,313,773 $ 22,587 $ (14,203) $ 4,322,157 December 31, 2020 MBS: Other U.S. obligations single-family MBS $ 2,622,677 $ 6,920 $ (4,590) $ 2,625,007 GSE single-family MBS 1,196,326 21,385 (1,177) 1,216,534 GSE multifamily MBS 882,299 255 (299) 882,255 Total HTM securities $ 4,701,302 $ 28,560 $ (6,066) $ 4,723,796 (1) Carrying value equals amortized cost, which includes adjustments made to the cost basis for purchase discount or premium and related accretion or amortization. Net unamortized premium at December 31, 2021 and 2020 totaled $28,440 and $7,101, respectively. Contractual Maturity. HTM securities are not presented by contractual maturity because they consisted entirely of MBS, whose actual maturities will likely differ from contractual maturities as borrowers have the right to prepay their obligations with or without prepayment fees. Allowance for Credit Losses. At December 31, 2021 and 2020 , 100% of our HTM securities were rated single-A, or above, by an NRSRO, based on the lowest long-term credit rating for each security. These may differ for any internal ratings of the securities, if applicable. Our HTM securities are evaluated for expected credit losses on a collective, or pooled, basis unless an individual assessment is deemed necessary, e.g. the securities do not possess similar risk characteristics. We consider several qualitative factors when evaluating the potential for credit losses on our HTM securities and, if deemed necessary, an allowance for credit losses is recorded. At December 31, 2021 and 2020, we did not record an allowance for credit losses on any of our HTM securities based on the following factors: (i) all securities were highly-rated, (ii) we have not experienced, nor do we expect, any payment defaults on the securities, (iii) the U.S., GSE, and other Agency obligations carry an explicit or implicit government guarantee such that we consider the risk of nonpayment to be zero, and (iv) we had no intention of selling any of these securities nor did we consider it more likely than not that we will be required to sell any of these securities.

Advances [Abstract]
Advances	Note 5 - Advances We offer a wide range of fixed- and adjustable-rate advance products with various maturities, interest rates, payment characteristics and optionality. Adjustable-rate advances have interest rates that reset periodically at a fixed spread to LIBOR or another specified index, including SOFR. Longer-term advances may be available subject to market conditions for both fixed-rate and adjustable-rate products. The following table presents advances outstanding by redemption term. December 31, 2021 December 31, 2020 Redemption Term Amount WAIR % Amount WAIR % Due in 1 year or less $ 7,863,703 0.59 $ 10,115,576 0.51 Due after 1 year through 2 years 2,684,996 2.02 2,149,839 1.57 Due after 2 years through 3 years 3,536,759 1.35 2,760,624 2.02 Due after 3 years through 4 years 2,931,260 1.29 3,725,103 1.36 Due after 4 years through 5 years 1,908,432 1.34 3,020,039 1.29 Thereafter 8,384,458 0.82 8,919,678 1.05 Total advances, par value 27,309,608 1.03 30,690,859 1.06 Fair-value hedging basis adjustments, net 179,115 645,946 Unamortized swap termination fees associated with modified advances, net of deferred prepayment fees 9,112 10,681 Total advances (1) $ 27,497,835 $ 31,347,486 (1) Carrying value equals amortized cost, which excludes accrued interest receivable at December 31, 2021 and 2020 of $13,075 and $14,961, respectively. We offer our members certain advances that provide them the right, at predetermined future dates, to call (i.e., prepay) the advance prior to maturity without incurring prepayment or termination fees. Borrowers typically exercise their call options for fixed-rate advances when interest rates decline. We also offer certain adjustable-rate advances that may be contractually prepaid by the borrower at the interest-rate reset date without incurring prepayment or termination fees. All other advances may only be prepaid by paying a fee that is sufficient to make us financially indifferent to the prepayment of the advance. We also offer putable advances. Under the terms of a putable advance, we retain the right to extinguish or put the fixed-rate advance to the member on predetermined future dates and offer replacement funding at current market rates, subject to certain conditions. The following table presents advances outstanding by the earlier of the redemption date or the next call date and next put date. Earlier of Redemption Earlier of Redemption December 31, December 31, December 31, December 31, Due in 1 year or less $ 12,547,866 $ 15,296,034 $ 13,452,703 $ 14,645,076 Due after 1 year through 2 years 2,578,396 1,797,049 3,090,101 3,107,339 Due after 2 years through 3 years 2,127,759 2,440,024 3,636,259 3,160,729 Due after 3 years through 4 years 1,997,060 2,246,102 3,007,160 3,824,603 Due after 4 years through 5 years 1,530,307 2,076,839 1,485,332 2,585,439 Thereafter 6,528,220 6,834,811 2,638,053 3,367,673 Total advances, par value $ 27,309,608 $ 30,690,859 $ 27,309,608 $ 30,690,859 Advance Concentrations . At December 31, 2021 and 2020, our top five borrowers held 43% and 44%, respectively, of total advances outstanding at par. Allowance for Credit Losses. Advances are evaluated for expected credit losses on a collective, or pooled, basis unless an individual assessment is deemed necessary, e.g. the advances do not possess similar risk characteristics. We manage our exposure to advances outstanding through an integrated approach that generally includes establishing a credit limit for each borrower, and an ongoing review of each borrower's financial condition, coupled with conservative collateral/lending policies to limit the risk of loss while balancing the borrower's needs for a reliable source of funding. In addition, we lend to eligible borrowers in accordance with federal statutes and Finance Agency regulations. Specifically, we comply with the Bank Act, which requires us to obtain sufficient collateral to fully secure credit products. We evaluate and update our collateral guidelines, as necessary, based on current market conditions. We accept certain investment securities, residential mortgage loans, deposits, and other real estate-related assets as collateral. In addition, certain members that qualify as CFIs are eligible to utilize expanded statutory collateral provisions for small business and agriculture loans. Under the Bank Act, our capital stock owned by our members serves as additional security. Collateral arrangements may vary depending upon borrower credit quality, financial condition and performance; borrowing capacity; and overall credit exposure to the borrower. To ensure that we are sufficiently protected, we evaluate and determine whether a member may retain physical possession of its collateral that is pledged to us or must specifically deliver the collateral to us or our document custody agent. Our evaluation of credit losses on advances utilizes a basic framework that considers the adequacy of the advances' associated collateral and the associated members' willingness and ability to pledge additional collateral to satisfy any current or anticipated future deficiency. Our agreements with borrowers allow us, at any time and in our sole discretion, to require substitution of collateral, adjust the over-collateralization requirements applied to collateral, or refuse to make extensions of credit against any collateral. We also may require borrowers to pledge additional collateral regardless of whether the collateral would be eligible to originate a new extension of credit. Our agreements with our borrowers also afford us the right, in our sole discretion, to declare any borrower to be in default if we deem our Bank to be inadequately secured. We determine the estimated value of the collateral required to secure each member's advances by applying collateral discounts, or haircuts, to the market value or UPB of the collateral, as applicable. Using a risk-based approach, we consider the amount and quality of the collateral pledged and the borrower's financial condition to be the primary indicators of an advance's credit quality. At December 31, 2021 and 2020, we had rights to collateral on a borrower-by-borrower basis with an estimated lendable value equal to or in excess of our advances outstanding. At December 31, 2021 and 2020, we did not have any advances that were past due, on non-accrual status, or considered impaired. In addition, there were no TDRs related to advances during the years ended December 31, 2021, 2020, or 2019. Based upon the collateral held as security, our credit extension and collateral policies, our credit analysis and the repayment history on advances, we have not recorded an allowance for credit losses on advances.

Receivables [Abstract]
Mortgage Loans Held for Portfolio	Note 6 - Mortgage Loans Held for Portfolio Mortgage loans held for portfolio consist substantially of residential loans acquired from our members through the MPP. The mortgage loans are fixed-rate and either credit enhanced by PFIs, if conventional, or guaranteed or insured by government agencies. The following tables present information on mortgage loans held for portfolio by term and type. The balances reflect the sale of a 90% participating interest in a $100 million MCC of certain newly acquired MPP loans to another FHLBank in 2016. Term December 31, 2021 December 31, 2020 Fixed-rate long-term mortgages $ 6,417,543 $ 7,257,237 Fixed-rate medium-term (1) mortgages 1,016,851 1,065,329 Total mortgage loans held for portfolio, UPB 7,434,394 8,322,566 Unamortized premiums 181,172 187,425 Unamortized discounts (2,389) (1,638) Hedging basis adjustments, net 3,157 7,642 Total mortgage loans held for portfolio 7,616,334 8,515,995 Allowance for credit losses (200) (350) Total mortgage loans held for portfolio, net (2) $ 7,616,134 $ 8,515,645 (1) Defined as a term of 15 years or less at origination. (2) Excludes accrued interest receivable at December 31, 2021 and 2020 of $27,977 and $34,151, respectively.

Our management of credit risk considers the several layers of loss protection that are defined in our agreements with the PFIs. Our loss protection consists of the following loss layers, in order of priority, (i) borrower equity; (ii) PMI up to coverage limits (when applicable for the acquisition of mortgages with an initial LTV ratio of over 80% at the time of purchase); (iii) available funds remaining in the LRA; and (iv) SMI coverage (as applicable) purchased by the seller from a third-party provider naming the Bank as the beneficiary, up to the policy limits. Any losses not absorbed by the loss protection are borne by the Bank. Government-Guaranteed or -Insured Mortgage Loans. These fixed-rate mortgage loans are guaranteed or insured by the FHA, Department of Veterans Affairs, Rural Housing Service of the Department of Agriculture, or HUD. The servicer provides and maintains a guaranty or insurance from the applicable government agency. The servicer is responsible for compliance with all government agency requirements and for obtaining the benefit of the applicable guaranty or insurance with respect to defaulted government-guaranteed or -insured mortgage loans. Any losses incurred on these loans that are not recovered from the insurer or guarantor are absorbed by the servicers. Credit Quality Indicators for Conventional Mortgage Loans and Other Delinquency Statistics. Payment status is the key credit quality indicator for conventional mortgage loans and allows us 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. The tables below present the key credit quality indicators and other delinquency statistics for our mortgage loans held for portfolio aggregated by (i) the most recent five origination years and (ii) all prior origination years. Amounts are based on amortized cost, which excludes accrued interest receivable. Origination Year Payment Status as of December 31, 2021 Prior to 2017 2017 to 2021 Total Past due: 30-59 days $ 16,968 $ 12,662 $ 29,630 60-89 days 4,175 1,767 5,942 90 days or more 18,599 11,206 29,805 Total past due 39,742 25,635 65,377 Total current 2,447,420 4,921,101 7,368,521 Total conventional mortgage loans, amortized cost $ 2,487,162 $ 4,946,736 $ 7,433,898 As of December 31, 2021, the UPB of conventional loans in an informal forbearance arrangement included amounts 30-59 days past due of $1,730, 60-89 days past due of $1,018, and 90 days or more past due of $16,634, for total past due of $19,382. Origination Year Payment Status as of December 31, 2020 Prior to 2016 2016 to 2020 Total Past due: 30-59 days $ 19,893 $ 22,130 $ 42,023 60-89 days 6,980 12,078 19,058 90 days or more 27,467 67,075 94,542 Total past due 54,340 101,283 155,623 Total current 2,468,908 5,635,070 8,103,978 Total conventional mortgage loans, amortized cost (1) $ 2,523,248 $ 5,736,353 $ 8,259,601 As of December 31, 2020, the UPB of conventional loans in an informal forbearance arrangement included amounts 30-59 days past due of $10,214, 60-89 days past due of $12,661, and 90 days or more past due of $79,011, for total past due of $101,886. Other Delinquency Statistics as of December 31, 2021 Conventional Government Total In process of foreclosure (1) $ 1,999 $ — $ 1,999 Serious delinquency rate (2) 0.40 % 0.86 % 0.41 % Past due 90 days or more still accruing interest (3) $ 15,725 $ 1,364 $ 17,089 On non-accrual status (4) $ 23,487 $ — $ 23,487 Other Delinquency Statistics as of December 31, 2020 In process of foreclosure (1) $ 2,689 $ — $ 2,689 Serious delinquency rate (2) 1.14 % 3.36 % 1.21 % Past due 90 days or more still accruing interest (3) $ 36,585 $ 7,933 $ 44,518 On non-accrual status (4) $ 87,763 $ — $ 87,763 (1) Includes loans for which the decision of foreclosure or similar alternative, such as pursuit of deed-in-lieu of foreclosure, has been reported. Loans in process of foreclosure are included in past due categories depending on their delinquency status, but are not necessarily considered to be on non-accrual status. (2) Represents loans 90 days or more past due (including loans in process of foreclosure) expressed as a percentage of the total mortgage loans. The percentage excludes principal and interest amounts previously paid in full by the servicers on conventional loans that are pending resolution of potential loss claims. Our servicers repurchase seriously delinquent government loans, including FHA loans, when certain criteria are met. (3) Although our past due scheduled/scheduled MPP loans are classified as loans past due 90 days or more based on the loan's delinquency status, we do not consider these loans to be on non-accrual status as they are well-secured and in the process of collection. (4) As of December 31, 2021 and 2020, $11,701 and $36,409, respectively, of UPB of these conventional mortgage loans on non-accrual status did not have a related allowance for credit losses because these loans were either previously charged off to the expected recoverable value and/or the fair value of the underlying collateral, including any credit enhancements, exceeded the amortized cost of the loans. Additionally, the UPB of these conventional mortgage loans on non-accrual status in informal forbearance arrangements related to the COVID-19 pandemic totaled $7,130 and $59,306, respectively. Allowance for Credit Losses. We apply a systematic approach for estimating expected credit losses on our conventional mortgage loans over their estimated remaining lives through analyses that include, among other considerations, various loan portfolio and collateral-related characteristics, past loan performance, current and historical economic conditions, and reasonable and supportable forecasts of expected economic conditions. We estimate expected losses on our conventional 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 losses on an individual basis. In addition, we individually evaluate all TDRs, any remaining exposure to delinquent conventional MPP loans paid in full by servicers, and collateral-dependent loans. Loans are considered collateral-dependent when a borrower is experiencing financial difficulty and repayment is expected to be substantially through the sale of the underlying collateral. We estimate expected losses on collateral-dependent loans by applying a practical expedient that considers the expected loss of a collateral-dependent loan to be equal to the difference between the amortized cost of the loan and the estimated fair value of the collateral, less estimated selling costs. When determining the allowance for credit losses, we consider how credit enhancements are expected to mitigate credit losses and then reduce the allowance accordingly because the credit enhancements are entered into in conjunction with the purchase of a loan and cannot be both legally detached and separately exercised. Collectively Evaluated Mortgage Loans. Conventional loans current to 179 days past due are collectively evaluated at the pool level using a recognized third-party credit and prepayment model, which considers both current and historical information and events and reasonable and supportable forecasts that rely upon certain key inputs and assumptions, to estimate potential ranges of credit loss exposure over the estimated life of the loans. One such key input is a 3-year forecast of housing prices with a 2-year gradual transition to full reversion to historical inputs after 5 years. Additionally, the evaluation is based upon distinct underlying loan characteristics, including loan vintage (year of origination), geographic location, credit support features and other factors, and a projected migration of loans through the various stages of delinquency. Seriously delinquent conventional loans 180 days or more past due and not charged-off are also collectively evaluated at the pool level based on loan-specific attribution data, including the use of loan-level property values from a third-party. Individually Evaluated Mortgage Loans. Certain conventional mortgage loans, primarily TDRs, are specifically identified for purposes of calculating the allowance for credit losses. The measurement of our allowance for individually evaluated loans considers loan-specific attribution data similar to homogeneous pools of delinquent loans evaluated on a collective basis, including the use of loan-level property values from a third-party. We also individually evaluate any remaining exposure to delinquent MPP conventional loans paid in full by the servicers. An estimate of the loss, if any, is equal to the estimated cost associated with maintaining and disposing of the property (which includes the UPB, interest owed on the delinquent loan to date, and estimated costs associated with disposing of the collateral) less the estimated fair value of the collateral (net of estimated selling costs) and the amount of credit enhancements including the PMI, LRA and SMI. The estimated fair value of the collateral is obtained from HUD statements, sales listings or other evidence of current expected liquidation amounts. Qualitative Factors. We also assess qualitative factors in our estimation of credit losses. These factors represent a subjective management judgment based on facts and circumstances that exist as of the reporting date that are not ascribed to any specific measurable economic or credit event and therefore may not otherwise be captured in our methodology. Rollforward of Allowance for Credit Losses. The table below presents a rollforward of our allowance for credit losses. Rollforward of Allowance 2021 2020 2019 Balance, beginning of year $ 350 $ 300 $ 600 Charge-offs (81) (140) (137) Recoveries 39 50 126 Provision for (reversal of) credit losses (108) 140 (289) Balance, end of year $ 200 $ 350 $ 300 Government-Guaranteed or -Insured Mortgage Loans. Based on the U.S. government guarantee or insurance on these loans, our assessment of our servicers, and the collateral backing the loans, we did not record an allowance for credit losses for government-guaranteed or -insured mortgage loans at December 31, 2021 or 2020. Furthermore, none of these mortgage loans have been placed on non-accrual status due to the U.S. government guarantee or insurance on these loans and the contractual obligation of the loan servicer to repurchase the loans when certain criteria are met.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives and Hedging Activities	Note 8 - Derivatives and Hedging Activities Nature of Business Activity. We are exposed to interest-rate risk primarily from the effect of changes in market interest rates on our interest-earning assets and on our interest-bearing liabilities that finance those assets. The goal of our interest-rate risk management strategies is not to eliminate interest-rate risk, but to manage it within appropriate limits. To mitigate the risk of loss, we have established policies and procedures, which include guidelines on the amount of exposure to changes in interest rates that we are willing to accept. In addition, we monitor the risk to our interest income, net interest margin and average maturity of interest-earning assets and interest-bearing liabilities. Consistent with Finance Agency regulation, we enter into derivatives to (i) manage the interest-rate risk exposures inherent in our otherwise unhedged assets and funding positions, (ii) achieve our risk management objectives, and (iii) act as an intermediary between our members and counterparties . Finance Agency regulation and our risk management policies prohibit trading in, or the speculative use of, these derivative instruments and limit credit risk arising from these instruments. However, the use of derivatives is an integral part of our financial management strategy. We use derivative financial instruments when they are the most cost-effective alternative to achieve our financial and risk management objectives. The most common ways in which we use derivatives are to: • reduce the interest-rate sensitivity and repricing gaps of assets and liabilities; • protect the value of existing asset and liability positions or of commitments and forecasted transactions; • mitigate the adverse earnings effects of the shortening or extension of the duration of certain assets (e.g., advances or mortgage assets) and liabilities; • reduce funding costs by executing a derivative concurrently with the issuance of a consolidated obligation as the cost of a combined funding structure can be lower than the cost of a comparable CO bond; • preserve a favorable interest-rate spread between the yield of an asset (e.g., an advance) and the cost of the related liability (e.g., CO bond used to fund advance); • manage embedded options in assets and liabilities; and • manage our overall asset/liability structure. We reevaluate our hedging strategies from time to time and, consequently, we may adopt new strategies or change our hedging techniques. We transact most of our derivatives with large banks and major broker-dealers. Some of these banks and broker-dealers or their affiliates buy, sell, and distribute consolidated obligations. We are not a derivatives dealer and thus do not trade derivatives for short-term profit. Over-the-counter derivative transactions may be either executed with a counterparty (uncleared derivatives) or cleared through a Futures Commission Merchant (i.e., clearing agent) with a clearinghouse (cleared derivatives). Once a derivative transaction has been accepted for clearing by a clearinghouse, the derivative transaction is novated, and the executing counterparty is replaced with the clearinghouse. Types of Derivatives. We use the following derivative instruments to reduce funding costs and to manage our exposure to interest-rate risks inherent in the normal course of business. Interest-Rate Swaps. The Bank uses interest-rate swaps to hedge the risk of changes in the fair value of certain of its assets and liabilities due to changes in market interest rates. The variable rate we receive or pay in most interest-rate swaps is currently indexed to LIBOR, EFFR, or SOFR. Interest-Rate Cap and Floor Agreements. Caps and floors are used to protect against the interest rate on a variable-rate asset or liability falling below or rising above a certain level. Interest-Rate Swaptions. To protect against the adverse effects of sudden increases or decreases in interest rates, we utilize payer or receiver swaptions, respectively. Forward Contracts. To protect against changes in the market values of fixed-rate MDCs resulting from changes in market interest rates, we normally sell TBA MBS or other derivatives for forward settlement. Types of Hedged Items. We document at inception all relationships between the derivatives designated as hedging instruments and the hedged items, our risk management objectives and strategies for undertaking various hedge transactions, and our method of assessing effectiveness. We have the following types of hedged items: Investments. We primarily invest in Agency MBS, U.S. Treasury securities, and GSE and TVA debentures, which may be classified as trading, HTM or AFS securities. The interest-rate, prepayment and duration risks associated with these investment securities are managed through a combination of debt issuance and derivatives. We may manage those risks by funding these investment securities with CO bonds that contain call features. We may also hedge the prepayment risk with caps or floors, callable swaps or swaptions. We may manage the risk and volatility arising from changing market prices of investment securities by matching the cash outflow on the derivatives with the cash inflow on the investment securities. Certain of these derivatives qualify as fair-value hedges while others are designated as economic hedges. Advances. We offer a wide range of fixed- and variable-rate advance products with different maturities, interest rates, payment characteristics, and optionality. We may use derivatives to manage the repricing and/or options characteristics of advances in order to more closely match the characteristics of our funding liabilities. In general, whenever a member executes a fixed-rate advance or an adjustable-rate advance with embedded options, we may simultaneously execute a derivative with terms that offset the terms and embedded options in the advance. For example, we may hedge a fixed-rate advance with an interest-rate swap where we pay a fixed rate and receive a variable rate, effectively converting the fixed-rate advance to an adjustable-rate advance. This type of hedge is typically treated as a fair-value hedge. In addition, we may hedge a callable, prepayable or putable advance by entering into a cancellable interest-rate swap. Mortgage Loans. We invest in fixed-rate mortgage loans. The prepayment options embedded in these mortgage loans can result in extensions or contractions in the expected repayment of these loans, depending on changes in prepayment speeds. We may purchase interest-rate caps and floors, swaptions, callable swaps, calls, and puts to minimize the prepayment risk embedded in the loans. These derivatives are considered economic hedges against the prepayment risk of the loans, but they are not specifically linked to individual loans. Consolidated Obligations. We may enter into derivatives to hedge the interest-rate risk associated with our debt issuances. We manage the risk and volatility arising from changing market prices of a consolidated obligation by matching the cash inflow on the derivative with the cash outflow on the consolidated obligation. In a typical transaction, we issue a fixed-rate consolidated obligation and simultaneously enter into a matching derivative in which the counterparty pays fixed cash flows to us designed to match in timing and amount the cash outflows we pay on the consolidated obligation. In turn, we pay a variable cash flow to the counterparty that closely matches the interest payments we receive on short-term or variable-rate advances (typically one- or three-month LIBOR or EFFR). These transactions are typically treated as fair-value hedges. Additionally, we may issue variable-rate CO bonds indexed to LIBOR, SOFR, or the United States prime rate and simultaneously execute interest-rate swaps to hedge the basis risk of the variable-rate debt. Firm Commitments. In connection with our purchases of mortgage loans, we enter into MDCs. Certain MDCs entered into by us are considered derivatives. The MDC and the TBA used in the firm commitment hedging strategy are treated as an economic hedge and are marked to fair value through earnings. When the MDC settles, the current fair value of the commitment is included with the basis of the mortgage loan and amortized accordingly. Managing Credit Risk on Derivatives. We are subject to credit risk due to the risk of nonperformance by the counterparties to our derivative transactions. We manage counterparty credit risk through credit analysis, collateral requirements and adherence to the requirements set forth in our policies, CFTC regulations, and Finance Agency regulations. Uncleared Derivatives. For uncleared derivatives, the degree of credit risk depends on the extent to which master netting arrangements are included in such contracts to mitigate the risk. We require collateral agreements with our uncleared derivatives. The exposure thresholds above which collateral must be delivered vary; the threshold is zero in some cases. Additionally, collateral related to derivatives with member institutions includes collateral assigned to us as evidenced by a written security agreement and held by the member institution for our benefit. For certain of our uncleared derivatives, we have credit support agreements that contain provisions requiring us to post additional collateral with our counterparties if there is deterioration in our credit rating. If our credit rating is lowered by an NRSRO, we could be required to deliver additional collateral on uncleared derivative instruments in net liability positions. The aggregate estimated fair value of all uncleared derivative instruments with credit-risk-related contingent features that were in a net liability position (before cash collateral and related accrued interest on cash collateral) at December 31, 2021 was $314, for which we have posted collateral in cash, including accrued interest, of $894 in the nor mal course of business. If our credit rating had been lowered by an NRSRO (from an S&P equivalent of AA+ to AA), we would not have been required to deliver additional collateral to our uncleared derivative counterparties at December 31, 2021. Cleared Derivatives. For cleared derivatives, the clearinghouse is our counterparty. We use LCH and CME as clearinghouses for all cleared derivative transactions. Collateral is required to be posted daily for changes in the value of cleared derivatives to mitigate each counterparty's credit risk. The clearinghouse notifies the clearing agent of the required initial and variation margin, and the clearing agent notifies us. The requirement that we post initial and variation margin through the clearing agent for the benefit of the clearinghouse exposes us to institutional credit risk in the event that the clearing agent or clearinghouse fails to meet its obligations. At both clearinghouses, initial margin is considered cash collateral and variation margin is characterized as daily settlement payments. The clearinghouse determines margin requirements which are generally not based on credit ratings. However, clearing agents may require additional margin to be posted by us based on credit considerations, including but not limited to any credit rating downgrades. At December 31, 2021, we were not required by our clearing agents to post any additional margin. Financial Statement Effect and Additional Financial Information. The notional amount of derivatives serves as a factor in determining periodic interest payments, or cash flows received and paid. The notional amount of derivatives also reflects the extent of our involvement in the various classes of financial instruments but represents neither the actual amounts exchanged nor our overall exposure to credit and market risk; the overall risk is much smaller. The risks of derivatives can be measured meaningfully on a portfolio basis that takes into account the counterparties, the types of derivatives, the items being hedged and any offsets between the derivatives and the hedged items. We record derivative instruments, related cash collateral received or pledged/posted and associated accrued interest on a net basis, by clearing agent and/or by counterparty when the netting requirements have been met. The following table presents the notional amount and estimated fair value of derivative assets and liabilities. December 31, 2021 December 31, 2020 Notional Derivative Derivative Notional Derivative Derivative Amount Assets Liabilities Amount Assets Liabilities Derivatives designated as hedging instruments: Interest-rate swaps $ 46,395,451 $ 105,446 $ 413,324 $ 40,227,966 $ 13,018 $ 761,330 Derivatives not designated as hedging instruments: Economic hedges: Interest-rate swaps 8,595,000 357 148 9,177,000 5,404 181 Interest-rate caps/floors 625,500 1,077 — 625,500 1,113 — Interest-rate forwards 98,200 1 199 180,900 — 1,486 MDCs 96,424 45 105 180,152 1,022 — Total derivatives not designated as hedging instruments 9,415,124 1,480 452 10,163,552 7,539 1,667 Total derivatives before adjustments $ 55,810,575 106,926 413,776 $ 50,391,518 20,557 762,997 Netting adjustments and cash collateral (1) 113,276 (401,591) 262,525 (740,018) Total derivatives, net $ 220,202 $ 12,185 $ 283,082 $ 22,979 (1) Represents the application of the netting requirements that allow us to settle (i) positive and negative positions and (ii) cash collateral and related accrued interest held or placed, with the same clearing agent and/or counterparty.

Deposit Liabilities	Note 9 - Deposit Liabilities We offer demand and overnight deposits to members and qualifying non-members. In addition, we offer short-term interest-bearing deposit programs to members. A member that services mortgage loans may deposit funds collected in connection with the mortgage loans, pending disbursement of such funds to the owners of the mortgage loans. We classify these items as other deposits. Demand, overnight, and other deposits pay interest based on a daily interest rate. Time deposits pay interest based on a fixed rate determined at the origination of the deposit. The following table presents the types of our interest-bearing and non-interest-bearing deposits.

Consolidated Obligations

Consolidated Obligations	12 Months Ended

Debt Disclosure [Abstract]
Consolidated Obligations	Note 10 - Consolidated Obligations Consolidated obligations consist of CO bonds and discount notes. CO bonds may be issued to raise short-, intermediate- and long-term funds for the FHLBanks and are not subject to any statutory or regulatory limits on maturity. Discount notes are issued primarily to raise short-term funds and have original maturities of up to one year. These notes generally sell at less than their face amount and are redeemed at par value when they mature. The FHLBanks issue consolidated obligations through the Office of Finance as their agent under the oversight of the Finance Agency and the United States Secretary of the Treasury. In connection with each debt issuance, each FHLBank specifies the amount of debt to be issued on its behalf. Each FHLBank records as a liability the specific portion of consolidated obligations issued on its behalf and for which it is the primary obligor. In addition to being the primary obligor for all consolidated obligations issued on our behalf, we are jointly and severally liable with each of the other FHLBanks for the payment of the principal and interest on all of the FHLBanks' consolidated obligations outstanding. The par values of the FHLBanks' consolidated obligations outstanding at December 31, 2021 and 2020 totaled $652.9 billion and $746.8 billion, respectively. As provided by the Bank Act and Finance Agency regulations, consolidated obligations are backed only by the financial resources of all FHLBanks. The Finance Agency, in its discretion, may require any FHLBank to make principal or interest payments due on any consolidated obligation whether or not the consolidated obligation represents a primary liability of that FHLBank. Although an FHLBank has never paid the principal or interest payments due on a consolidated obligation on behalf of another FHLBank, if that event should occur, Finance Agency regulations provide that the paying FHLBank is entitled to reimbursement for any payments made on behalf of another FHLBank and other associated costs, including interest to be determined by the Finance Agency. If, however, the Finance Agency determines that such other FHLBank is unable to satisfy its repayment obligations to the paying FHLBank, then the Finance Agency may allocate the outstanding liability of such other FHLBank among the remaining FHLBanks on a pro-rata basis in proportion to their participation in all outstanding consolidated obligations, or in any other manner it may determine to ensure that the FHLBanks operate in a safe and sound manner. We do not believe that it is probable that we will be asked or required to make principal or interest payments on behalf of another FHLBank. Discount Notes.

To meet the specific needs of certain investors in CO bonds, both fixed-rate and variable-rate CO bonds may contain features that result in complex coupon payment terms and call options. When these CO bonds are issued, we may enter into derivatives containing features that offset the terms and embedded options, if any, of the CO bonds. CO bonds may also be callable.

Affordable Housing Program [Abstract]
Affordable Housing Program	Note 11 - Affordable Housing Program The Bank Act requires each FHLBank to establish an AHP, in which the FHLBank provides subsidies in the form of direct grants to members that use the funds to assist in the purchase, construction, or rehabilitation of housing for very low-, low-, and moderate-income households. Annually, the FHLBanks must set aside for the AHP the greater of the aggregate of $100 million or 10% of each FHLBank's net earnings. For purposes of the AHP calculation, net earnings is defined in a Finance Agency Advisory Bulletin as income before assessments, plus interest expense related to MRCS. The following table summarizes the activity in our AHP funding obligation.

Capital

Capital	12 Months Ended

Banking Regulation, Total Capital [Abstract]
Capital	Note 12 - Capital We are a cooperative whose member and former member institutions own all of our capital stock. Former members (including certain non-member institutions that own our capital stock as a result of a merger with or acquisition of a member) own our capital stock solely to support credit products or mortgage loans still outstanding on our statement of condition. Member shares cannot be purchased or sold except between us and our members or, with our written approval, among our members, at the par value of one hundred dollars per share, as mandated by our capital plan and Finance Agency regulation. Classes of Capital Stock . Our capital plan divides our Class B stock into two sub-series: Class B-1 and Class B-2. Class B-1 stock is held by our members to satisfy their membership stock requirements, while Class B-2 stock is held to satisfy their activity-based stock requirements. A member's Class B-1 stock is reclassified as B-2 as needed to help fulfill the member's activity-based stock requirement, and the member may be required to purchase additional Class B-2 stock to fully meet that requirement. Any excess stock is automatically classified as Class B-1. Our capital plan also permits the board of directors to authorize the issuance of Class A stock although, as of December 31, 2021, the board of directors had not authorized such issuance. If authorized, a member may elect to purchase Class A stock, rather than Class B-2 stock, to satisfy the member’s activity-based stock requirement, subject to certain restrictions. The following table presents the capital stock outstanding by sub-series. Capital Stock Outstanding December 31, 2021 December 31, 2020 Class B-1 $ 931,517 $ 797,196 Class B-2 1,314,684 1,410,374 Total Class B $ 2,246,201 $ 2,207,570 Dividends. Our board of directors may, but is not required to, declare and pay dividends on our Class B stock in either cash or capital stock or a combination thereof, as long as we are in compliance with Finance Agency regulations. The amount of the dividend to be paid is based on the average number of shares of each sub-series held by the member during the dividend payment period (applicable quarter). Our capital plan does not mandate a specific difference between Class B-1 and Class B-2 dividend rates. Rather, the board of directors may declare a dividend rate on Class B-2 stock that is equal to or greater than the rate on Class B-1 stock. The plan also authorizes the board of directors to declare a dividend rate on Class A stock (if issued and outstanding) that is equal to or greater than the rate on Class B-1 stock. Stock Redemption and Repurchase. In accordance with the Bank Act, our capital stock is considered putable by the member. Members can redeem Class B stock, subject to certain restrictions, by giving five years' written notice. Members can redeem Class A stock, subject to certain restrictions, by giving six months written notice. Any member that withdraws from membership or otherwise has had its membership terminated may not be readmitted as a member for a period of five years from the divestiture date for all capital stock that was held as a condition of membership, as set forth in our capital plan and Finance Agency regulations, unless the member has canceled or revoked its notice of withdrawal prior to the end of the applicable redemption period. This restriction does not apply if the member is transferring its membership from one FHLBank to another on an uninterrupted basis. We may repurchase, at our sole discretion, any member's capital stock that exceeds the required minimum amount, subject to significant statutory and regulatory restrictions on our right to repurchase, or obligation to redeem, the outstanding stock. As a result, whether or not a member may have its capital stock repurchased or redeemed will depend, in part, on whether we are in compliance with those restrictions. We are not required to redeem a member's required capital stock until the expiration of the notice of redemption, or until the activity to which the capital stock relates no longer remains outstanding, whichever is later. If activity-based stock becomes excess stock (i.e., the amount of stock held by a member or former member in excess of the stock ownership requirement for that institution) as a result of an activity no longer remaining outstanding, we may repurchase the excess stock at our discretion, subject to the statutory and regulatory restrictions. A member may cancel or revoke its written notice of redemption or its notice of withdrawal from membership prior to the conclusion of the applicable redemption period. However, our capital plan provides that we may charge a cancellation fee to a member that cancels or revokes its withdrawal notice. Through December 31, 2021, certain members had requested redemptions of their Class B stock, but the related stock outstanding at December 31, 2021 and 2020 totaling $14,637 and $314, respectively, was not considered mandatorily redeemable and reclassified to MRCS because the requesting members may revoke their requests, without substantial penalty, throughout the five-year waiting period. Therefore, these requests are not considered sufficiently substantive in nature. However, we consider redemption requests related to mergers, acquisitions or charter terminations, as well as involuntary terminations from membership, to be sufficiently substantive when made and, therefore, the related stock is considered mandatorily redeemable and reclassified to MRCS. Mandatorily Redeemable Capital Stock. The following table presents the activity in our MRCS. MRCS Activity 2021 2020 2019 Liability at beginning of year $ 250,768 $ 322,902 $ 168,876 Reclassification from capital stock 4,730 32,791 150,978 Reductions due to change in membership status — — 3,704 Redemptions/repurchases (205,076) (104,965) (1,255) Accrued distributions — 40 599 Liability at end of year $ 50,422 $ 250,768 $ 322,902 The following table presents MRCS by contractual year of redemption. The year of redemption is the later of (i) the final year of the five-year redemption period, or (ii) the first year in which a non-member no longer has an activity-based stock requirement.

(2) Balance at December 31, 2021 includes $11,835 of Class B stock held by one captive insurance company whose membership was terminated on February 19, 2021 but will not be repurchased until the associated credit products and other obligations are no longer outstanding. Such amount was properly classified as "thereafter" as of December 31, 2020. (3) Balance represents Class B stock held by two captive insurance companies whose five-year redemption period began immediately upon their respective terminations of membership on February 19, 2021. Upon their respective terminations, we repurchased their excess stock totaling $18,063 . An additional $1,125 of excess stock was repurchased in September 2021. When a member's membership status changes to a non-member, the member's capital stock is reclassified to MRCS. If such change occurs during a quarterly dividend period, but not at the beginning or the end of a quarterly period, any dividends for that quarterly period are allocated between distributions from retained earnings for the shares held as capital stock during that period and interest expense for the shares held as MRCS during that period. Therefore, the distributions from retained earnings represent dividends to former members for only the portion of the period that they were members. The amounts recorded to interest expense represent dividends to former members for the portion of that period and subsequent periods that they were not members. The following table presents the distributions related to MRCS.

We are subject to three capital requirements under our capital plan and Finance Agency regulations: (i) Risk-based capital. We must maintain at all times permanent capital, defined as Class B stock (including MRCS) and retained earnings, in an amount at least equal to the sum of our credit risk, market risk, and operational risk capital requirements, all of which are calculated in accordance with Finance Agency regulations. The Finance Agency may require us to maintain a greater amount of permanent capital than is required by the risk-based capital requirements as defined. (ii) Total regulatory capital. We are required to maintain at all times a total capital-to-assets ratio of at least 4%. Total regulatory capital is the sum of permanent capital, any general loss allowance, if consistent with GAAP and not held against specific assets, and other amounts from sources determined by the Finance Agency as available to absorb losses. For regulatory capital purposes, AOCI is not considered capital. (iii) Leverage capital. We are required to maintain at all times a leverage capital-to-assets ratio of at least 5%. Leverage capital is defined as the sum of (a) permanent capital weighted 1.5 times and (b) all other components of total capital. As presented in the following table, we were in compliance with these Finance Agency's capital requirements at December 31, 2021 and 2020.

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, FICO. The capitalization of FICO was provided by capital distributions from the FHLBanks to FICO in 1987, 1988 and 1989 that aggregated to $680 million in exchange for FICO nonvoting capital stock. Upon passage of the Financial Institutions Reform, Recovery and Enforcement Act of 1989, the Bank's previous investment in capital stock of FICO was determined to be non-redeemable and, therefore, the Bank charged-off its prior capital distributions to FICO directly against retained earnings. Upon the dissolution of FICO in October 2019, FICO determined that excess funds aggregating to $200 million were available for distribution to its sole stockholders, the FHLBanks. Specifically, the Bank received $10,574 during the year ended December 31, 2020 which was determined based on our proportionate ownership of FICO's nonvoting capital stock. The Bank treated the receipt of these funds as a partial recovery of the prior capital distributions made by the Bank to FICO. These funds were credited to unrestricted retained earnings.

Retirement Benefits [Abstract]
Employee Retirement and Deferred Compensation Plans	Note 14 - Employee Retirement and Deferred Compensation Plans Qualified Defined Contribution Plan. The Bank participated in a tax-qualified multiple-employer retirement savings plan through October 1, 2020. Effective October 2, 2020, the Bank adopted a tax-qualified single-employer plan. The terms of such plans are substantially the same. This DC plan covers our officers and employees who meet certain eligibility requirements. The Bank makes a matching contribution equal to a percentage of voluntary employee contributions, subject to certain limitations. In addition, the Bank makes a non-elective contribution to the account of each participant who is not eligible to participate in the Bank's DB plan. During the years ended December 31, 2021, 2020 and 2019, we contribut ed $2,682, $2,810 , and $2,778, respectively. Qualified Defined Benefit Pension Plan. We participate in a tax-qualified, defined benefit pension plan for financial institutions administered by Pentegra Retirement Services. This DB Plan is treated as a multiemployer plan for accounting purposes but operates as a multiple-employer plan under the Employee Retirement Income Security Act of 1974 and the Internal Revenue Code. As a result, certain multiemployer plan disclosures are not applicable. Under the DB Plan, contributions made by a participating employer may be used to provide benefits to employees of other participating employers because assets contributed by an employer are not segregated in a separate account or restricted to provide benefits to employees of that employer only. Also, in the event that a participating employer is unable to meet its contribution or funding requirements, the required contributions for the other participating employers (including us) could increase proportionately. Our contributions to the DB Plan for the fiscal years e nded December 31, 2021, 2020 and 2019 were not more than 5% of the total contributions to the DB Plan by all participating employers for the plan years ended June 30, 2020, 2019 and 2018, respectively. Our DB Plan covers our officers and employees who meet certain eligibility requirements, including an employment date prior to February 1, 2010. The DB Plan operates on a fiscal year from July 1 through June 30 and files one Form 5500 on behalf of all participating employers. The most recent Form 5500 available for the DB Plan is for the plan year ended June 30, 2020. The Employer Identification Number is 13-5645888 and the three digit plan number is 333. There are no collective bargaining agreements in place. The DB Plan's annual valuation process includes calculating its funded status and separately calculating the funded status of each participating employer. The funded status is calculated as the market value of plan assets divided by the funding target (100% of the present value of all benefit liabilities accrued at that date utilizing the discount rate prescribed by statute). The calculation of the funding target as of July 1, 2021, 2020 and 2019 incorporated a higher discount rate in accordance with MAP-21, which resulted in a lower funding target and a higher funded status. Over time, the favorable impact of MAP-21 is expected to decline. As permitted by the Employee Retirement Income Security Act of 1974, the DB Plan accepts contributions for the prior plan year up to eig ht and a half months after the asset valuation date. As a result, the market value of plan assets at the valuation date (July 1) will increase by any subsequent contributions designated for the immediately preceding plan year ended June 30. The following table presents a summary of net pension costs charged to compensation and benefits expense and the DB Plan's funded status. DB Plan Net Pension Cost and Funded Status 2021 2020 2019 Net pension cost charged to compensation and benefits expense for the year ended December 31 (1) $ 5,482 $ 3,211 $ 3,500 DB Plan funded status as July 1 130 % (a) 108 % (b) 109 % Our funded status as of July 1 126 % 104 % 109 % (1) Includes voluntary contributions for the years ended December 31, 2021, 2020 and 2019 of $4,112, $1,944, and $2,856, respectively. (a) The DB Plan's funded status as of July 1, 2021 is preliminary and may increase because the participating employers are permitted to make designated contributions for the plan year ended June 30, 2021 through March 15, 2022. Any such contributions will be included in the final valuation as of July 1, 2021. The final funded status as of July 1, 2021 will not be available until the Form 5500 for the plan year ended June 30, 2022 is filed (no later than April 2023). (b) The DB Plan's final funded status as of July 1, 2020 will not be available until the Form 5500 for the plan year ended June 30, 2021 is filed (no later than April 2022). Nonqualified Defined Benefit Supplemental Retirement Plan. We participate in a nonqualified, single-employer, unfunded supplemental executive retirement plan. This SERP restores all of the defined benefits to participating employees who have had their qualified defined benefits limited by Internal Revenue Service regulations. Because the SERP is a nonqualified unfunded plan, no contributions are required to be made. However, we may elect to make contributions to a related grantor trust that we established to indirectly fund the SERP in order to maintain a desired funding level. Payments of benefits may be made from the related grantor trust or from our general assets. The following table presents the changes in our SERP benefit obligation. Change in benefit obligation 2021 2020 2019 Projected benefit obligation at beginning of year $ 58,330 $ 42,719 $ 27,593 Service cost 3,528 2,489 1,636 Interest cost 1,067 1,086 1,039 Actuarial loss 119 12,551 13,079 Benefits paid (523) (515) (628) Settlements (5,665) — — Plan amendment (6,279) — — Projected benefit obligation at end of year $ 50,577 $ 58,330 $ 42,719 The actuarial loss includes the impact of the changes in the discount rate, compensation, mortality, demographics and other components used to calculate the projected benefit obligation at December 31 of each year. The amendment to the SERP was adopted to enhance the retention of key employees by providing greater predictability of the dollar amount of benefits payable upon separation of employment or retirement from the Bank. The amendment substantially reduces fluctuations of the dollar value of the retirement benefits because the applicable retirement plan interest rates and mortality tables used to calculate benefits were set as of specific dates in 2021 rather than as of the employee’s date of separation of employment or retirement. The following table presents the key assumptions used in the actuarial calculations of the benefit obligation. December 31, 2021 2020 2019 Discount rate 2.29 % 1.54 % 2.55 % Compensation increases 5.50 % 5.50 % 5.50 % The discount rate represents a weighted average that was determined by a discounted cash-flow approach, which incorporates the timing of each expected future benefit payment. We estimate future benefit payments based on the census data of the SERP's participants, benefit formulas and provisions, and valuation assumptions reflecting the probability of decrement and survival. We then determine the present value of the future benefit payments by using duration-based interest-rate yields from the Financial Times Stock Exchange Pension Discount Curve as of the measurement date, and solving for the single discount rate that produces the same present value of the future benefit payments. The accumulated benefit obligation for the SERP, which excludes projected future salary increases as of December 31, 2021 and 2020 was $36,545 an d $42,739 , respectively. The unfunded benefit obligation is reported in other liabilities. Although there are no plan assets, the assets in the related grantor trust, included as a component of other assets, had a total estimated fair v alue at December 31, 2021 and 2020 of $55,008 and $45,200, respectively. The following table presents the components of the net periodic benefit cost for the SERP. Years Ended December 31, 2021 2020 2019 Net periodic benefit cost: Service cost $ 3,528 $ 2,489 $ 1,636 Total recognized in compensation and benefits 3,528 2,489 1,636 Interest cost 1,067 1,086 1,039 Amortization of net actuarial loss 3,706 3,469 1,941 Accelerated amortization of net actuarial loss due to settlements 2,769 — — Total recognized in other expenses 7,542 4,555 2,980 Total net periodic benefit cost recognized in income before assessments 11,070 7,044 4,616 Pension benefits recognized in OCI: Actuarial loss 119 12,551 13,079 Amortization of net actuarial loss (3,706) (3,469) (1,941) Accelerated amortization of net actuarial loss due to settlements (2,769) — — Past service credit due to plan amendment (6,279) — — Net pension benefits recognized in OCI (12,635) 9,082 11,138 Total recognized as net periodic benefit cost $ (1,565) $ 16,126 $ 15,754 The following table presents the key assumptions used in the actuarial calculations to determine net periodic benefit cost for the SERP.

Segment Information

Segment Information	12 Months Ended

Segment Reporting [Abstract]
Segment Information	Note 15 - Segment Information We report based on two operating segments: • Traditional, which consists of credit products (including advances, standby letters of credit, and lines of credit), investments (including federal funds sold, securities purchased under agreements to resell, interest-bearing demand deposit accounts, and investment securities), and correspondent services and deposits; and • Mortgage loans, which consists substantially of mortgage loans purchased from our members through our MPP. These segments reflect our two primary mission asset activities and the manner in which they are managed from the perspective of development, resource allocation, product delivery, pricing, credit risk and operational administration. The segments identify the principal ways we provide services to members. We measure the performance of each segment based upon the net interest spread of the underlying portfolio(s). Therefore, each segment's performance begins with net interest income. Traditional net interest income is derived primarily from the difference, or spread, between the interest income earned on advances and investments and the borrowing costs related to those assets, net interest settlements and changes in fair value related to certain interest-rate swaps, and related premium and discount amortization. Traditional also includes the costs related to holding deposits for members and other miscellaneous borrowings. Mortgage loan net interest income is derived primarily from the difference, or spread, between the interest income earned on mortgage loans, including the premium and discount amortization, and the borrowing costs related to those loans. Direct other income and expense also affect each segment's results. The traditional segment includes the direct earnings impact of certain derivatives and hedging activities related to advances, investments and consolidated obligations as well as all other miscellaneous income and expense not associated with mortgage loans. The mortgage loans segment includes the direct earnings impact of derivatives and hedging activities as well as direct compensation, benefits and other expenses (including an allocation for indirect overhead) associated with operating the MPP and volume-driven costs associated with master servicing and quality control fees. The assessments related to AHP have been allocated to each segment based upon its proportionate share of income before assessments. The following table presents our financial performance by operating segment. Year Ended December 31, 2021 Traditional Mortgage Loans Total Net interest income $ 229,505 $ 22,035 $ 251,540 Provision for (reversal of) credit losses — (108) (108) Other income (loss) (33,495) (324) (33,819) Other expenses 96,760 16,465 113,225 Income before assessments 99,250 5,354 104,604 Affordable Housing Program assessments 10,185 535 10,720 Net income $ 89,065 $ 4,819 $ 93,884 Year Ended December 31, 2020 Net interest income $ 253,683 $ 9,687 $ 263,370 Provision for (reversal of) credit losses — 140 140 Other income (loss) (52,262) (3,254) (55,516) Other expenses 92,953 16,181 109,134 Income (loss) before assessments 108,468 (9,888) 98,580 Affordable Housing Program assessments (credits) 11,706 (989) 10,717 Net income (loss) $ 96,762 $ (8,899) $ 87,863 Year Ended December 31, 2019 Net interest income $ 181,367 $ 55,875 $ 237,242 Provision for (reversal of) credit losses — (289) (289) Other income (loss) 20,166 143 20,309 Other expenses 84,638 14,356 98,994 Income before assessments 116,895 41,951 158,846 Affordable Housing Program assessments 12,876 4,195 17,071 Net income $ 104,019 $ 37,756 $ 141,775 We have not symmetrically allocated assets to each segment based upon financial results as it is impracticable to measure the performance of our segments from a total assets perspective. As a result, there is asymmetrical information presented in the tables above including, among other items, the allocation of depreciation without an allocation of the depreciable assets, derivatives and hedging earnings adjustments with no corresponding allocation to derivative assets, if any, and the recording of interest income with no allocation to accrued interest receivable. The following table presents our asset balances by operating segment.

Estimated Fair Values

Fair Value Disclosures [Abstract]
Estimated Fair Value	Note 16 - Estimated Fair Values We estimate fair value amounts by using available market and other pertinent information and the most appropriate valuation methods. Although we use our best judgment in estimating the fair values of financial instruments, there are inherent limitations in any valuation technique. Therefore, these estimated fair values may not be indicative of the amounts that would have been realized in market transactions at the reporting dates. Certain estimates of the fair value of financial assets and liabilities are highly subjective and require judgments regarding significant factors such as the amount and timing of future cash flows, prepayment speeds, interest-rate volatility, and the 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 . GAAP establishes a fair value hierarchy and requires us to maximize the use of significant observable inputs and minimize the use of significant unobservable inputs when measuring estimated fair value. The inputs are evaluated, and an overall level for the estimated fair value measurement is determined. This overall level is an indication of the extent of the market observability of the estimated fair value measurement for the asset or liability. The fair value hierarchy prioritizes the inputs used to measure fair value into three broad levels: Level 1 Inputs. Quoted prices (unadjusted) for identical assets or liabilities in an active market that we 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 or contractual term, a level 2 input must be observable for substantially the full term of the asset or liability. Level 2 inputs include (i) quoted prices for similar assets or liabilities in active markets; (ii) quoted prices for identical or similar assets or liabilities in markets that are not active; (iii) 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 (iv) 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. Valuations are derived from techniques that use significant assumptions not observable in the market, which include pricing models, discounted cash flow models, or similar techniques. We review the fair value hierarchy classifications on a quarterly basis. Changes in the observability of the inputs may result in a reclassification of certain assets or liabilities. There were no such reclassifications during the years ended December 31, 2021, 2020, or 2019. The following tables present the carrying value and estimated fair value of each of our financial instruments. The total of the estimated fair values does not represent an estimate of our overall market value as a going concern, which would take into account, among other considerations, future business opportunities and the net profitability of assets and liabilities.

(2) Included in other assets on the statement of condition. Summary of Valuation Techniques and Significant Inputs. The valuation techniques and significant inputs used to develop our measurement of estimated fair value for assets and liabilities that are measured at fair value on a recurring or non-recurring basis in the Statement Condition are listed below. Investment Securities - MBS. The estimated fair value incorporates prices from multiple third-party pricing vendors, when available. These pricing vendors use various proprietary models to price MBS. The inputs to those models are derived from various sources, including, but not limited to, benchmark yields, reported trades, dealer estimates, issuer spreads, benchmark securities, bids, offers, and other market-related data. We conduct reviews of the pricing vendors' processes, methodologies and control procedures to confirm and further augment our understanding of the vendors' prices for our MBS. Each pricing vendor has an established challenge process in place for all MBS valuations, which facilitates resolution of potentially erroneous prices identified by us. Our valuation technique for estimating the fair values of MBS initially requires the establishment of a "median" price for each security. All prices that are within a specified tolerance threshold of the median price are then included in the "cluster" of prices that are averaged to compute a "default" price. All prices that are outside the threshold (i.e., outliers) are subject to further analysis (including, but not limited to, comparison to prices provided by an additional third-party valuation service, prices for similar securities, and/or non-binding dealer estimates) to determine if an outlier is a better estimate of fair value. If so, then the outlier (or the other price as appropriate) is used as the final price rather than the default price. In all cases, the final price is used to determine the estimated fair value of the security. As of December 31, 2021 and 2020 , we obtained two or three prices for substantially all of our MBS. Investment Securities - non-MBS. The estimated fair value is determined using market-observable price quotes from third-party pricing vendors, such as the Composite Bloomberg Bond Trader screen, thus falling under the market approach. Impaired Mortgage Loans Held for Portfolio. We record non-recurring fair value adjustments to reflect partial charge-offs on impaired mortgage loans. We estimate the fair value of these assets using a current property value obtained from a third-party. Derivative assets/liabilities. We base the estimated fair values of derivatives with similar terms on market prices when available. However, active markets do not exist for many of our derivatives. Consequently, fair values for these instruments are generally estimated using standard valuation techniques such as discounted cash-flow analysis and comparisons to similar instruments. In limited instances, fair value estimates for derivatives are obtained from dealers and are corroborated by using a pricing model and observable market data (e.g., the LIBOR or OIS curves). A discounted cash flow analysis utilizes market-observable inputs (inputs that are actively quoted and can be validated to external sources). Inputs by class of derivative are as follows: Interest-rate related: • LIBOR curve or the OIS/SOFR curve, as applicable, to project cash flows for collateralized interest-rate swaps and the OIS/SOFR curve only to discount those cash flows; and • Volatility assumption - market-based expectations of future interest-rate volatility implied from current market prices for similar options. TBAs: • TBA securities prices - market-based prices are determined by coupon, maturity and expected term until settlement. MDCs: • TBA securities prices - prices are then adjusted for differences in coupon, average loan rate and seasoning. The estimated fair values of our derivative assets and liabilities include accrued interest receivable/payable and related cash collateral. The estimated fair values of the accrued interest receivable/payable and cash collateral equal their carrying values due to their short-term nature. We adjust the estimated fair values of our derivatives for counterparty nonperformance risk, particularly credit risk, as appropriate. We compute our nonperformance risk adjustment by using observable credit default swap spreads and estimated probability default rates applied to our exposure after considering collateral held or placed. Grantor Trust Assets. Grantor trust assets, included as a component of other assets, are carried at estimated fair value based on quoted market prices as of the last business day of the reporting period. Estimated Fair Value Measurements . The following tables present, by level within the fair value hierarchy, the estimated fair value of our financial assets and liabilities that are recorded at estimated fair value on a recurring or non-recurring basis on our statement of condition.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 17 - Commitments and Contingencies The following table presents our off-balance-sheet commitments at their notional amounts. December 31, 2021 Type of Commitment Expire within one year Expire after one year Total Standby letters of credit outstanding $ 39,022 $ 373,694 $ 412,716 Unused lines of credit (1) 879,035 — 879,035 Commitments to fund additional advances (2) 38,000 — 38,000 Commitments to fund or purchase mortgage loans, net (3) 96,424 — 96,424 Unsettled CO bonds, at par 30,000 — 30,000 (1) Maximum line of credit amount per member is $100,000. (2) Generally for periods up to six months. (3) Generally for periods up to 91 days. Commitments to Extend Credit. A standby letter of credit is a financing arrangement between us and one of our members for which we charge the member a commitment fee. If we are required to make a payment for a beneficiary's draw, the payment amount is converted into a collateralized advance to the member. Substantially all of these standby letters of credit, including related commitments, range from 3 months to 20 years, although some are renewable at our option. The carrying value of guarantees (commitment fees) related to standby letters of credit is recorded in other liabilities and totaled $12,796 at December 31, 2021. Lines of credit allow members to fund short-term cash needs (up to one year) without submitting a new application for each request for funds. Liability for Credit Losses. We monitor the creditworthiness of our members that have standby letters of credit and lines of credit. As standby letters of credit and lines of credit are subject to the same collateralization and borrowing limits that apply to advances and are fully collateralized at the time of issuance, we have not recorded a liability for credit losses on these credit products. Commitments to Fund or Purchase Mortgage Loans. Commitments that unconditionally obligate us to fund or purchase mortgage loans are generally for periods not to exceed 91 days. Such commitments are reported as derivative assets or derivative liabilities at their estimated fair value and are reported net of participating interests sold to other FHLBanks. Pledged Collateral. At December 31, 2021 and 2020, we had pledged cash collateral of $515,740 and $1,003,380, respectively, to counterparties and clearing ag ents. At December 31, 2021 and 2020, we had not pledged any securities as collateral. Legal Proceedings. We are subject to legal proceedings arising in the normal course of business. We record an accrual for a loss contingency when it is probable that a loss for which we could be liable has been incurred and the amount can be reasonably estimated. After consultation with legal counsel, management is not aware of any such proceedings where the ultimate liability, if any, could have a material effect on our financial condition, results of operations or cash flows. Additional discussion of other commitments and contingencies is provided in Note 5 - Advances; Note 6 - Mortgage Loans Held for Portfolio; Note 8 - Derivatives and Hedging Activities; Note 10 - Consolidated Obligations; Note 12 - Capital; and Note 16 - Estimated Fair Values .

Related Party Transactions [Abstract]
Related Party and Other Transactions	Note 18 - Related Party and Other Transactions We are a cooperative whose members and former members (or legal successors) own all of our outstanding capital stock. Former members (including certain non-members) are required to maintain their investment in our capital stock until their outstanding business transactions with us have matured or are paid off and their capital stock is redeemed in accordance with our capital plan and regulatory requirements. For more information, see Note 12 - Capital . Under GAAP, transactions with related parties include transactions with principal owners, i.e, owners of more than 10% of the voting interests of the entity. Due to the statutory limits on members' voting rights and the number of our members, no shareholder owned more than 10 percent of the total voting interests as of and for the three-year period ended December 31, 2021. Therefore, the Bank had no transactions with principal owners for any of the periods presented. Under GAAP, transactions with related parties also include transactions with management. Management is defined as persons who are responsible for achieving the objectives of the entity and who have the authority to establish policies and make decisions by which those objectives are to be pursued. For this purpose, management typically includes those who serve on our board of directors. Transactions with Directors Financial Institutions. The Bank provides, in the ordinary course of its business, products and services to members whose officers or directors may also serve as directors of the Bank, i.e., directors' financial institutions. However, Finance Agency regulations require that transactions with directors' financial institutions be made on the same terms as those with any other member. Therefore, all of our transactions with directors' financial institutions are subject to the same eligibility and credit criteria, as well as the same conditions, as comparable transactions with all other members. The following table presents our transactions with directors' financial institutions, taking into account the beginning and ending dates of the directors' terms, merger activity and other changes in the composition of directors' financial institutions. Years Ended December 31, Transactions with Directors' Financial Institutions 2021 2020 2019 Net capital stock issuances (redemptions and repurchases) $ 7,213 $ 80,088 $ 6,729 Net advances (repayments) (1,581,708) 346,863 203,078 Mortgage loan purchases 58,830 48,394 30,610 The following table presents the aggregate balances of capital stock and advances outstanding for directors' financial institutions and their balances as a percent of the total balances on our statement of condition.

Transactions with Members and Former Members. Substantially all advances are made to members, and all whole mortgage loans held for portfolio are purchased from members. We also maintain demand deposit accounts for members, primarily to facilitate settlement activities that are directly related to advances or mortgage loan purchases. Such transactions with members are entered into in the ordinary course of business. In addition, we may purchase investments in federal funds sold, securities purchased under agreements to resell, certificates of deposit, and MBS from members or their affiliates. All purchases are transacted at market prices without preference to the status of the counterparty or the issuer of the security as a member, nonmember, or affiliate thereof. Under our AHP, we provide subsidies to members, which may be in the form of direct grants or below-market-rate advances. All AHP subsidies are made in the ordinary course of business. Under our Community Investment Program and our Community Investment Cash Advances program, we provide subsidies in the form of below-market-rate advances to members or standby letters of credit to members for community lending and economic development projects. All Community Investment Cash Advances subsidies are made in the ordinary course of business. Transactions with Other FHLBanks. Occasionally, we loan or borrow short-term funds to/from other FHLBanks. There were no loans to or borrowings from other FHLBanks that remained outstanding at December 31, 2021 or 2020. Transactions with the Office of Finance. Our proportionate share of the cost of operating the Office of Finance is identified in our statement of income. For the determination of our proportionate share, see Note 1 - Summary of Significant Accounting Policies.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2021
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation. The accompanying financial statements have been prepared in accordance with GAAP and SEC requirements. The financial statements contain all adjustments that are, in the opinion of management, necessary for a fair statement of the Bank's financial position, results of operations and cash flows for the periods presented. All such adjustments were of a normal recurring nature.
Use of Estimates	Use of Estimates. When preparing financial statements in accordance with GAAP, we are required to make subjective assumptions and estimates that may affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities, and the reported amounts of income and expense. Although the reported amounts and disclosures reflect our best estimates, actual results could differ significantly from these estimates. The most significant estimates pertain to the fair values of financial instruments. Estimated Fair Value. The estimated fair value amounts, recorded on the statement of condition and presented in the accompanying disclosures, reflect appropriate valuation methods and have been determined based on the assumptions that we believe market participants would use in pricing the asset or liability. Although we use our best judgment in estimating fair value, there are inherent limitations in any valuation technique. Therefore, these estimated fair values may not be indicative of the amounts that would have been realized in market transactions on the reporting dates. For more information, see Note 16 - Estimated Fair Values .
Reclassifications	Reclassifications. We have reclassified certain amounts reported in prior periods to conform to the current period presentation. These reclassifications had no effect on total assets, total liabilities, total capital, net income, total comprehensive income or net cash flows.
Interest-Bearing Deposits, Securities Purchased under Agreements to Resell, and Federal Funds Sold	Interest-Bearing Deposits, Securities Purchased under Agreements to Resell, and Federal Funds Sold. These investments provide short-term liquidity and are carried at cost. Securities purchased under agreements to resell are treated as short-term, collateralized financings. These securities are held in safekeeping in the Bank's name by third-party custodians approved by us. If the market value of the underlying assets declines below the market value required as collateral, the counterparty must (i) place an equivalent amount of additional securities in safekeeping in the Bank's name, and/or (ii) remit an equivalent amount of cash. Federal funds sold are short-term, unsecured loans that are generally transacted on an overnight term. Finance Agency regulations include a limit on the amount of unsecured credit an individual FHLBank may extend to a counterparty.
Investment Securities	Investment Securities. Purchases and sales of securities are recorded on a trade date basis. We classify investments as trading, HTM or AFS at the date of acquisition. Trading Securities. Securities classified as trading are held for liquidity purposes and carried at fair value. We record changes in the fair value of these securities through other income as net gains (losses) on trading securities. Finance Agency regulation and our risk management policies prohibit the speculative use of these instruments and limit the credit risk arising from these securities. HTM Securities. Securities for which we have both the positive intent and ability to hold to maturity are classified as HTM. The carrying value includes adjustments made to the cost basis of the security for purchase discount and related accretion, purchase premium and related amortization, and collection of principal. Certain changes in circumstances may cause us to change our intent to hold a particular security to maturity without necessarily calling into question our intent to hold other debt securities to maturity. Thus, the sale or transfer of an HTM security due to certain changes in circumstances, such as evidence of significant deterioration in the issuer's creditworthiness or changes in regulatory requirements, is not considered to be inconsistent with its original classification. Other events may also cause us to sell or transfer an HTM security without necessarily calling into question our intent to hold other debt securities to maturity, but such events must be isolated, non-recurring, unusual, and could not have been reasonably anticipated. Sales of HTM debt securities that meet either of the following two conditions may be considered as maturities for purposes of the classification of securities: (i) the sale occurs near enough to its maturity date (or call date, if exercise of the call is probable) that interest-rate risk is substantially eliminated as a pricing factor and any changes in market interest rates would not have a significant effect on the security's fair value, or (ii) the sale occurs after we have already collected a substantial portion (at least 85%) of the principal outstanding at acquisition due either to prepayments or to scheduled payments payable in equal installments (both principal and interest) over its term. AFS Securities. Securities that are not classified as trading or HTM are classified as AFS and carried at estimated fair value. We record changes in the fair value of these securities in OCI as net change in unrealized gains (losses) on AFS securities, except for AFS securities in hedging relationships that qualify as fair-value hedges. For those securities, we record the portion of the change in fair value attributable to the risk being hedged in interest income together with the related change in the fair value of the derivative, and record the remainder of the change in the fair value in OCI as net change in unrealized gains (losses) on AFS securities. Amortization of Purchase Premiums and Discounts. Since we hold a large number of similar loans underlying our MBS, for which prepayments are probable and the timing and amount of prepayments can be reasonably estimated, we amortize or accrete premiums, discounts, and cumulative fair-value hedging basis adjustments on MBS to interest income using a level-yield under the retrospective interest method. This method requires that we estimate prepayments over the estimated life of each security and retrospectively adjust the effective yield each time the estimated remaining cash flows change as if the new estimate had been used since the original acquisition date. Changes in interest rates are a significant assumption used in estimating the timing and amount of prepayments. For all non-MBS securities, we amortize or accrete premiums, discounts, and cumulative fair-value hedging basis adjustments using a level-yield methodology over the contractual life of each security, with the exception of our callable non-MBS securities, on which the purchase premium is amortized to the next call date. For all non-MBS securities, prepayments are not estimated but only taken into account as they actually occur. Gains and Losses on Sales. We compute gains and losses on sales of investment securities using the specific identification method and include these gains and losses in other income as net realized gains (losses) from sale of securities.
Advances	Advances. We record advances at amortized cost, adjusted to include deferred swap termination fees associated with modified advances, net of deferred prepayment fees, and cumulative fair-value hedging basis adjustments. We amortize such fees and hedging basis adjustments t o interest income using a level-yield methodology over the contractual life of the advance. When an advance is prepaid, we amortize to interest income a proportionate share of the remaining balance of those adjustments. Prepayment Fees. We charge a prepayment fee when a borrower repays certain advances prior to maturity. We report prepayment fees, net of any associated swap termination fees and cumulative fair-value hedging basis adjustments, in interest income on advances. Advance Modifications. When we fund a new advance concurrent with, or within a short period of time after, the prepayment of an original advance, we determine whether the transaction is effectively either (i) two separate transactions (the prepayment of the original advance and the disbursement of a new advance), defined as an advance extinguishment, or (ii) the continuation of the original advance as modified, defined as an advance modification. We account for the transaction as an extinguishment if both of the following criteria are met: (i) the effective yield of the new advance is at least equal to the effective yield for a comparable advance to a member with similar collection risks who is not prepaying, and (ii) modifications of the original advance are determined to be more than minor, i.e., if the present value of the cash flows under the terms of the new advance is at least 10% different from the present value of the remaining cash flows under the original advance or through an evaluation of qualitative factors, which may include changes in the interest-rate exposure to the member by moving from a fixed to an adjustable-rate advance. In all other instances, the transaction is accounted for as an advance modification. If the transaction is determined to be an advance extinguishment, we recognize income from nonrefundable prepayment fees, net of associated swap termination fees, in the period that the extinguishment occurs. Alternatively, if no prepayment fees are received (e.g., the member requests that we embed the prepayment fee into the rate of the new advance), the excess of the present value of the cash flows of the new advance over those of an advance with a current market rate and otherwise comparable terms is immediately recognized in income, and the basis of the new advance is adjusted accordingly. If the transaction is determined to be an advance modification, the nonrefundable prepayment fees, net of associated swap termination fees, are not immediately recognized in income but are (i) included in the carrying value of the modified advance and amortized into interest income over the life of the new advance using a level-yield methodology or (ii) embedded into the rate of the modified advance and recorded as an adjustment to the interest accrual. Allowance for Credit Losses. Advances are evaluated for expected credit losses on a collective, or pooled, basis unless an individual assessment is deemed necessary, e.g. the advances do not possess similar risk characteristics. We manage our exposure to advances outstanding through an integrated approach that generally includes establishing a credit limit for each borrower, and an ongoing review of each borrower's financial condition, coupled with conservative collateral/lending policies to limit the risk of loss while balancing the borrower's needs for a reliable source of funding. In addition, we lend to eligible borrowers in accordance with federal statutes and Finance Agency regulations. Specifically, we comply with the Bank Act, which requires us to obtain sufficient collateral to fully secure credit products. We evaluate and update our collateral guidelines, as necessary, based on current market conditions. We accept certain investment securities, residential mortgage loans, deposits, and other real estate-related assets as collateral. In addition, certain members that qualify as CFIs are eligible to utilize expanded statutory collateral provisions for small business and agriculture loans. Under the Bank Act, our capital stock owned by our members serves as additional security. Collateral arrangements may vary depending upon borrower credit quality, financial condition and performance; borrowing capacity; and overall credit exposure to the borrower. To ensure that we are sufficiently protected, we evaluate and determine whether a member may retain physical possession of its collateral that is pledged to us or must specifically deliver the collateral to us or our document custody agent. Our evaluation of credit losses on advances utilizes a basic framework that considers the adequacy of the advances' associated collateral and the associated members' willingness and ability to pledge additional collateral to satisfy any current or anticipated future deficiency. Our agreements with borrowers allow us, at any time and in our sole discretion, to require substitution of collateral, adjust the over-collateralization requirements applied to collateral, or refuse to make extensions of credit against any collateral. We also may require borrowers to pledge additional collateral regardless of whether the collateral would be eligible to originate a new extension of credit. Our agreements with our borrowers also afford us the right, in our sole discretion, to declare any borrower to be in default if we deem our Bank to be inadequately secured.
Mortgage Loans Held for Portfolio	Mortgage Loans Held for Portfolio. We classify mortgage loans, for which we have the positive intent and ability to hold for the foreseeable future or until maturity or payoff, as held for portfolio. Accordingly, these mortgage loans are reported at cost, adjusted to include premiums paid to and discounts received from PFIs, hedging basis adjustments, and the allowance for credit losses. Amortization of Purchase Premiums and Discounts. We amortize or accrete premiums and discounts and hedging basis adjustments to interest income using a level-yield methodology over the contractual life of each loan. When a loan is prepaid, we amortize to interest income a proportionate share of the remaining balance of those adjustments. Non-accrual Loans. We place a conventional mortgage loan on non-accrual status if it is determined that either (i) the collection of interest or principal is doubtful, or (ii) interest or principal is past due for 90 days or more, except when the loan is well secured and in the process of collection (e.g., through credit enhancements and monthly servicer remittances on a scheduled/scheduled basis). On loans with remittances on a scheduled/scheduled basis, we receive monthly principal and interest payments from the servicer regardless of whether the borrower has made payments to the servicer. Monthly servicer remittances on loans on an actual/actual basis may also be well secured; however, servicers on actual/actual remittance do not advance principal and interest due, regardless of borrower creditworthiness, until the payments are received from the borrower or when the loan is repaid. As a result, these loans are placed on non-accrual status once they become 90 days delinquent. A government-guaranteed or -insured mortgage loan is not placed on non-accrual status when the collection of the contractual principal or interest is 90 days or more past due because of the contractual obligation of the loan servicer to pay defaulted interest at the contractual rate. For those mortgage loans placed on non-accrual status, accrued but uncollected interest is reversed against interest income (for any interest accrued in the current year) and/or the allowance for credit losses (for any interest accrued in the previous year). We record payments received on non-accrual loans as a direct reduction of the amortized cost of the loan. When the amortized cost has been fully collected, any additional amounts collected are recognized as interest income. A loan on non-accrual status may be restored to accrual status when it becomes current (zero days past due) and three consecutive and timely monthly payments have been received. Loan Participations. We may sell participating interests in MPP loans acquired from our PFIs to other FHLBanks. The terms of the sale of these participating interests meet the accounting requirements for a sale and, therefore, the participating interests are derecognized from our reported mortgage loan balances and a pro-rata portion of the fixed LRA is assumed by the participating FHLBank for its use in loss mitigation. As a result, available funds remaining in our LRA are limited to our pro-rata portion of the fixed LRA that is associated with the participating interests retained by us. The portion of the participation fees received related to our upfront costs is recognized immediately into income, while the remaining portion related to our ongoing costs is deferred and amortized to income over the remaining life of the participated loans. Allowance for Credit Losses. We apply a systematic approach for estimating expected credit losses on our conventional mortgage loans over their estimated remaining lives through analyses that include, among other considerations, various loan portfolio and collateral-related characteristics, past loan performance, current and historical economic conditions, and reasonable and supportable forecasts of expected economic conditions. We estimate expected losses on our conventional 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 losses on an individual basis. In addition, we individually evaluate all TDRs, any remaining exposure to delinquent conventional MPP loans paid in full by servicers, and collateral-dependent loans. Loans are considered collateral-dependent when a borrower is experiencing financial difficulty and repayment is expected to be substantially through the sale of the underlying collateral. We estimate expected losses on collateral-dependent loans by applying a practical expedient that considers the expected loss of a collateral-dependent loan to be equal to the difference between the amortized cost of the loan and the estimated fair value of the collateral, less estimated selling costs. When determining the allowance for credit losses, we consider how credit enhancements are expected to mitigate credit losses and then reduce the allowance accordingly because the credit enhancements are entered into in conjunction with the purchase of a loan and cannot be both legally detached and separately exercised.
Allowance for Credit Losses	Troubled Debt Restructuring. A TDR related to MPP loans typically occurs when a concession is granted to a borrower for economic or legal reasons related to the borrower's financial difficulties that would not have been otherwise considered. Although we do not participate in government-sponsored loan modification programs, we do consider certain conventional loan modifications to be TDRs when the modification agreement permits the recapitalization of past due amounts, generally up to the original loan amount. If a borrower is having financial difficulty and a significant concession has been granted by the PFI with our approval, the loan modification is considered a TDR. No other terms of the original loan are modified, except for the possible extension of the contractual maturity date on a case-by-case basis. In no event does the borrower's original interest rate change. As a result of temporary accounting guidance that remained in effect throughout 2021, we continued excluding all qualifying COVID-19-related loan modifications considered to be formal, i.e. the legal terms of the loan were changed, from TDR classification and accounting. We do not consider any short-term, informal, i.e. the legal terms of the loan have not changed, modifications or payment deferrals alone to be a TDR and thus we continue to follow our existing past-due, non-accrual, TDR and charge-off accounting policies for such loan modifications. Modifications of government loans are not considered or accounted for as TDRs because we anticipate no loss of principal or interest accrued at the original contract rate, or significant delay, due to the government guarantee or insurance. Charge-Offs. A charge-off is recorded to the extent that the amortized cost (including UPB, unamortized premiums or discounts, and hedging basis adjustments) in a loan will not be fully recovered. We record a charge-off on a conventional mortgage loan against the credit loss allowance upon the occurrence of a confirming event. Confirming events include, but are not limited to, the settlement of a claim against any of the credit enhancements, delinquency in excess of 180 days unless we can clearly document that the delinquent loan is well-secured and in-process of collection, and filing for bankruptcy protection. We charge off the portion of the outstanding conventional mortgage loan balance in excess of the fair value of the underlying property, less costs to sell and adjusted for any available credit enhancements.
Allowance for Credit Losses on Financial Instruments	Allowance for Credit Losses on Financial Instruments. As a result of adopting new accounting guidance on January 1, 2020, our financial instruments, i.e. interest-bearing deposits, securities purchased under agreements to resell, federal funds sold, investment securities, advances (including off-balance sheet credit exposures), and mortgage loans held for portfolio, are evaluated quarterly for expected credit losses. If necessary, an allowance for credit losses is recorded with a corresponding adjustment to the provision for credit losses. The allowance for credit losses excludes uncollectible accrued interest receivable for all instruments, which is measured separately. If necessary, we write-off uncollectible accrued interest with a reversal of interest income.
Derivatives and Hedging Activities	Derivatives and Hedging Activities. We record derivative instruments, related cash collateral (including initial margin received or pledged/posted), variation margin received or pledged/posted, and associated accrued interest on a net basis, by clearing agent and/or by counterparty, as either derivative assets or derivative liabilities at their estimated fair values. Changes in the estimated fair value of derivatives are recorded in current period earnings. Designations. Derivatives are recorded beginning on the trade date and typically executed and designated in a qualifying hedging relationship at the same time as the acquisition of the hedged item. We may also designate the hedging relationship upon the Bank's commitment to disburse an advance, purchase financial instruments, or trade a consolidated obligation in which settlement occurs within the shortest period of time possible for the type of instrument based on market settlement conventions. Each derivative is designated as one of the following: (i) a qualifying hedge of the change in fair value of a recognized asset or liability (e.g., advances, AFS investments, and CO bonds) or an unrecognized firm commitment (fair-value hedge); or (ii) a non-qualifying hedge for asset/liability management purposes (economic hedge). In all cases involving a fair-value hedge of a recognized asset, liability or firm commitment, the designated risk being hedged is the risk of changes in the fair value of the hedged item attributable to changes in the designated benchmark interest rate. Accounting for Qualifying Hedges. Hedging relationships must meet certain criteria including, but not limited to, formal documentation of the hedging relationship and an expectation to be highly effective to qualify for hedge accounting. Two approaches to account for qualifying fair-value hedge relationships include: (i) Shortcut hedge accounting - Transactions that meet certain criteria qualify for the shortcut method of hedge accounting. Under the shortcut method, an assumption can be made that the entire change in fair value of a hedged item, due to changes in the benchmark rate, equates to the entire change in fair value of the related derivative. As a result, the derivative is considered to be perfectly effective in achieving offsetting changes in the fair value of the hedged asset or liability attributable to the hedged risk. When applying the shortcut method, we document, at inception of the hedge relationship, a quantitative long-haul method that we can apply should we subsequently determine a derivative relationship no longer qualifies for shortcut hedge accounting; or (ii) Long-haul hedge accounting - T he application of long-haul hedge accounting requires us to assess whether the derivatives used in hedging transactions are highly effective in offsetting changes in the fair value of hedged items or forecasted transactions attributable to the hedged risk and whether those derivatives may be expected to remain highly effective in future periods. As part of the assessment, a regression analysis is performed at the inception of each hedging relationship and at each month-end thereafter to ensure the hedge relationship has been highly effective historically and is expected to be highly effective in the future. While a number of long-haul methods and techniques are permissible, we utilize the following: • Total Contractual Coupon Method - In calculating the change in the fair value of the hedged item attributable to changes in the benchmark interest rate, the estimated coupon cash flows are based on the full contractual coupon cash flows. • Benchmark Component Method - In calculating the change in fair value of the hedged item attributable to changes in the benchmark interest rate, the credit and any other risks embedded in the contractual coupon rate are excluded from the estimated coupon cash flows by aligning the interest component of the swap with the hedged item. Given this alignment, the application of the benchmark component method generally results in less hedge ineffectiveness in comparison to the total contractual coupon method. Changes in the fair value of a derivative that is designated and qualifies as a fair-value hedge, along with changes in the fair value of the hedged asset or liability that are attributable to the hedged risk, are recorded in net interest income in the same line as the earnings effect of the hedged item. Accounting for Non-Qualifying Hedges. An economic hedge is defined as a derivative that hedges specific or non-specific underlying assets, liabilities, or firm commitments and does not qualify, or was not designated, for hedge accounting. As a result, we recognize only the net interest settlements and the change in fair value of these derivatives in other income as net gains (losses) on derivatives with no offsetting fair-value adjustments in earnings for the hedged assets, liabilities, or firm commitments. An economic hedge by definition, therefore, introduces the potential for earnings variability. Accrued Interest Receivables and Payables. The difference between the interest receivable and payable on a derivative designated as a qualifying hedge is recognized as an adjustment to the income or expense of the designated hedged item. The difference between the interest receivable and payable on economic hedges are recognized in other income as net gains (losses) on derivatives. Discontinuance of Hedge Accounting. We discontinue hedge accounting prospectively when: (i) the hedging relationship ceases to be highly effective; (ii) the derivative and/or the hedged item expires or is sold, terminated, or exercised; (iii) a hedged firm commitment no longer meets the definition of a firm commitment; or (iv) we elect to discontinue hedge accounting. When hedge accounting is discontinued and the derivative and hedged item remain, we: (i) continue to carry the derivative on the statement of condition at fair value as an economic hedge; (ii) cease adjusting the hedged asset or liability for changes in fair value; and (iii) amortize the cumulative basis adjustment on the hedged item into interest income over the remaining life of the hedged item using a level-yield methodology. When we discontinue a qualifying hedge relationship by terminating the derivative and subsequently designating the associated hedged item into a new qualifying hedge relationship, we: (i) recognize the cumulative gain (loss) on the derivative in current earnings; (ii) pay or receive a termination fee with the counterparty, substantially offsetting the recognized gain (loss) on the derivative; (iii) cease adjusting the hedged asset or liability for changes in fair value; and (iv) amortize the cumulative basis adjustment on the hedged item into interest income over the remaining life of the hedged item using a level-yield methodology. Embedded Derivatives. We may issue consolidated obligations, disburse advances, or purchase financial instruments in which a derivative instrument is embedded. In order to determine whether an embedded derivative must be bifurcated from the host instrument and separately valued, we must assess, upon execution of the transaction, whether the economic characteristics of the embedded derivative are clearly and closely related to the economic characteristics of the remaining component of the consolidated obligation, advance or purchased financial instrument (the host contract) and whether a separate, non-embedded instrument with the same terms as the embedded instrument would meet the definition of a derivative instrument.
Financial Instruments Meeting Netting Requirements	Financial Instruments Meeting Netting Requirements . We present certain financial instruments, including our derivative asset and liability positions as well as cash collateral received or pledged, on a net basis when we have a legal right of offset and all other requirements for netting are met (collectively referred to as the netting requirements). The net exposure for these financial instruments can change on a daily basis; therefore, there may be a delay between the time a change in the exposure is identified and additional collateral is requested, and the time the additional collateral is received or pledged. Likewise, there may be a delay before excess collateral is returned. For derivative instruments that meet the netting requirements, any excess cash collateral received or pledged is recognized as a derivative liability or derivative asset, respectively. For derivative instruments that do not meet the netting requirements, cash collateral is recognized as an interest-bearing asset or liability, as appropriate. Additional information regarding these transactions is provided in Note 8 - Derivatives and Hedging Activities.
Premises, Software, and Equipment	Premises, Software, and Equipment. We record premises, software, and equipment at cost, less accumulated depreciation and am ortization, in other assets, and compute depreciation and amortization using the straight-line method over their respective estimated useful lives, which range from 3 to 40 years. W
Consolidated Obligations	Consolidated Obligations. Consolidated obligations are recorded at amortized cost, adjusted to include concessions, discounts, premiums, principal payments, and cumulative fair-value hedging basis adjustments. Discounts and Premiums. We accrete or amortize the discounts and premiums as well as cumulative fair-value hedging basis adjustments to interest expense using a level-yield methodology over the term to contractual maturity of the corresponding CO bond. When we prepay a CO bond, a proportionate share of the remaining balance of those adjustments is recognized as interest income. Concessions. Concessions are paid to dealers in connection with the issuance of certain consolidated obligations. The Office of Finance prorates the amount of our concession based upon the percentage of the debt issued on the Bank's behalf. We record concessions paid on consolidated obligations as a direct deduction from their carrying amounts, consistent with the presentation of discounts on consolidated obligations. The concessions are deferred and amortized, using a level-yield methodology, to interest expense over the term to contractual maturity of the corresponding consolidated obligation. When we prepay a CO bond, a proportionate share of any remaining balance of concessions is recognized as interest expense.
Mandatorily Redeemable Capital Stock	Mandatorily Redeemable Capital Stock. When a member withdraws or attains non-member status by merger or acquisition, charter termination, relocation or other involuntary termination from membership, the member's shares are then subject to redemption, at which time a five-year redemption period commences for Class B stock. Since the shares meet the definition of a mandatorily redeemable financial instrument, the shares are reclassified from capital to liabilities as MRCS at estimated fair value, which is equal to par value. Dividends declared on shares classified as a liability are accrued at the expected dividend rate and reported as interest expense. We reclassify MRCS from liabilities to capital when non-members subsequently become members through either acquisition, merger, or election. After the reclassification, dividends declared on that capital stock are no longer classified as interest expense.
Restricted Retained Earnings	Restricted Retained Earnings. In accordance with our JCE Agreement, we allocate 20% of the Bank's net income each quarter to a separate restricted retained earnings account until the balance of that account, calculated as of the
Employee Retirement and Deferred Compensation Plans	Employee Retirement and Deferred Compensation Plans. We recognize the required contribution to the DB Plan ratably over the plan year to which it relates. Without a prefunding election, any contribution made in excess of the minimum required contribution is recorded as an expense in the quarterly reporting period in which the contribution is made; with a prefunding election, such excess contribution is recorded as a prepaid asset. Settlement gains and losses are recognized in earnings when the cost of all settlements during a year is greater than the sum of the service and interest cost components of the net periodic pension cost for the year.
Finance Agency Expenses	Finance Agency Expenses. The portion of the Finance Agency's expenses and working capital fund not allocated to Freddie Mac and Fannie Mae is allocated among the FHLBanks as assessments, which are based on the ratio of each FHLBank's minimum required regulatory capital to the aggregate minimum required regulatory capital of every FHLBank. We record our share of these assessments in other expenses.
Office of Finance Expenses	Offi ce of Finance Expenses. Our proportionate share of the Office of Finance's operating and capital expenditures is calculated based upon two components as follows: (i) two-thirds based on our share of total consolidated obligations outstanding and (ii) one-third base d on equal pro-rata allocation. We record our share of these expenditures in other expenses.
Cash Flows	Cash Flows. We consider cash and due from banks on the statement of condition as cash and cash equivalents within the statement of cash flows because of their highly liquid nature. Federal funds sold, securities purchased under agreements to resell, and interest-bearing deposits are not treated as cash and cash equivalents, but instead are treated as short-term investments. Accordingly, their associated cash flows are reported in the investing activities section of the statement of cash flows.
Recently Adopted Accounting Guidance	We did not adopt any new accounting guidance or elect to apply certain optional expedients prescribed by existing accounting guidance that were applicable and available during the year ended December 31, 2021. Further, the FASB did not issue any new and applicable accounting guidance in 2021.
Segment Reporting	We report based on two operating segments: • Traditional, which consists of credit products (including advances, standby letters of credit, and lines of credit), investments (including federal funds sold, securities purchased under agreements to resell, interest-bearing demand deposit accounts, and investment securities), and correspondent services and deposits; and • Mortgage loans, which consists substantially of mortgage loans purchased from our members through our MPP. These segments reflect our two primary mission asset activities and the manner in which they are managed from the perspective of development, resource allocation, product delivery, pricing, credit risk and operational administration. The segments identify the principal ways we provide services to members. We measure the performance of each segment based upon the net interest spread of the underlying portfolio(s). Therefore, each segment's performance begins with net interest income. Traditional net interest income is derived primarily from the difference, or spread, between the interest income earned on advances and investments and the borrowing costs related to those assets, net interest settlements and changes in fair value related to certain interest-rate swaps, and related premium and discount amortization. Traditional also includes the costs related to holding deposits for members and other miscellaneous borrowings. Mortgage loan net interest income is derived primarily from the difference, or spread, between the interest income earned on mortgage loans, including the premium and discount amortization, and the borrowing costs related to those loans. Direct other income and expense also affect each segment's results. The traditional segment includes the direct earnings impact of certain derivatives and hedging activities related to advances, investments and consolidated obligations as well as all other miscellaneous income and expense not associated with mortgage loans. The mortgage loans segment includes the direct earnings impact of derivatives and hedging activities as well as direct compensation, benefits and other expenses (including an allocation for indirect overhead) associated with operating the MPP and volume-driven costs associated with master servicing and quality control fees.
Fair Value Measurement	We estimate fair value amounts by using available market and other pertinent information and the most appropriate valuation methods. Although we use our best judgment in estimating the fair values of financial instruments, there are inherent limitations in any valuation technique. Therefore, these estimated fair values may not be indicative of the amounts that would have been realized in market transactions at the reporting dates. Certain estimates of the fair value of financial assets and liabilities are highly subjective and require judgments regarding significant factors such as the amount and timing of future cash flows, prepayment speeds, interest-rate volatility, and the 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 . GAAP establishes a fair value hierarchy and requires us to maximize the use of significant observable inputs and minimize the use of significant unobservable inputs when measuring estimated fair value. The inputs are evaluated, and an overall level for the estimated fair value measurement is determined. This overall level is an indication of the extent of the market observability of the estimated fair value measurement for the asset or liability. The fair value hierarchy prioritizes the inputs used to measure fair value into three broad levels: Level 1 Inputs. Quoted prices (unadjusted) for identical assets or liabilities in an active market that we 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 or contractual term, a level 2 input must be observable for substantially the full term of the asset or liability. Level 2 inputs include (i) quoted prices for similar assets or liabilities in active markets; (ii) quoted prices for identical or similar assets or liabilities in markets that are not active; (iii) 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 (iv) 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. Valuations are derived from techniques that use significant assumptions not observable in the market, which include pricing models, discounted cash flow models, or similar techniques.
Fair Value Transfer	We review the fair value hierarchy classifications on a quarterly basis. Changes in the observability of the inputs may result in a reclassification of certain assets or liabilities.

We offer our members certain advances that provide them the right, at predetermined future dates, to call (i.e., prepay) the advance prior to maturity without incurring prepayment or termination fees. Borrowers typically exercise their call options for fixed-rate advances when interest rates decline. We also offer certain adjustable-rate advances that may be contractually prepaid by the borrower at the interest-rate reset date without incurring prepayment or termination fees. All other advances may only be prepaid by paying a fee that is sufficient to make us financially indifferent to the prepayment of the advance. We also offer putable advances. Under the terms of a putable advance, we retain the right to extinguish or put the fixed-rate advance to the member on predetermined future dates and offer replacement funding at current market rates, subject to certain conditions.
