FEDERAL HOME LOAN BANK OF DALLAS
NOTES TO INTERIM UNAUDITED FINANCIAL STATEMENTS

Note 1—Basis of Presentation
The accompanying interim financial statements of the Federal Home Loan Bank of Dallas (the “Bank”) are unaudited and have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions provided by Article 10, Rule 10-01 of Regulation S-X promulgated by the Securities and Exchange Commission (“SEC”). Accordingly, they do not include all of the information and disclosures required by generally accepted accounting principles for complete financial statements. 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 interim periods presented. All such adjustments were of a normal recurring nature. The results of operations for the periods presented are not necessarily indicative of the results to be expected for the full fiscal year or any other interim period.
The Bank’s significant accounting policies and certain other disclosures are set forth in the notes to the audited financial statements for the year ended December 31, 2019.2020. The interim financial statements presented herein should be read in conjunction with the Bank’s audited financial statements and notes thereto, which are included in the Bank’s Annual Report on Form 10-K for the year ended December 31, 20192020 filed with the SEC on March 25, 202024, 2021 (the “2019“2020 10-K”). The notes to the interim financial statements update and/or highlight significant changes to the notes included in the 20192020 10-K.
The Bank is one of 11 district Federal Home Loan Banks, each individually a “FHLBank” and collectively the “FHLBanks,” and, together with the Office of Finance, a joint office of the FHLBanks, the “FHLBank System.” The Office of Finance manages the sale and servicing of the FHLBanks’ consolidated obligations. The Federal Housing Finance Agency (“Finance Agency”), an independent agency in the executive branch of the U.S. government, supervises and regulates the housing government-sponsored enterprises ("GSEs"), including the FHLBanks and the Office of Finance.
     Use of Estimates and Assumptions. The preparation of financial statements in conformity with U.S. GAAP requires management to make assumptions and estimates. These assumptions and estimates may affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities, and the reported amounts of income and expenses. Significant estimates include the valuations of the Bank’s investment securities (including, but not limited to, its investments in mortgage-backed securities ("MBS")), as well as its derivative instruments and any associated hedged items. Actual results could differ from these estimates.

Note 2—Recently AdoptedIssued Accounting Guidance
Credit Losses on Financial Instruments. Reference Rate Reform. On June 16, 2016,March 12, 2020, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2016-13, "Measurement of Credit Losses on Financial Instruments" ("ASU 2016-13"), which amends the guidance for the accounting for credit losses on financial instruments by replacing the incurred loss methodology with an expected credit loss methodology. Among other things, ASU 2016-13 requires:
entities to present financial assets, or groups of financial assets, measured at amortized cost at the net amount expected to be collected, which is computed by deducting an allowance for credit losses from the amortized cost basis of the financial asset(s);
the measurement of expected credit losses to be based upon relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount;
the statement of income to reflect the measurement of credit losses for newly recognized financial assets, as well as the expected increases or decreases in expected credit losses that have taken place during the period;
entities to determine the allowance for credit losses for purchased financial assets with a more-than-insignificant amount of credit deterioration since origination ("PCD assets") that are measured at amortized cost in a manner similar to other financial assets measured at amortized cost (the initial allowance for credit losses on PCD assets is added to the purchase price rather than being reported as a credit loss expense);
credit losses relating to available-for-sale debt securities to be recorded through an allowance for credit losses, the amount of which is limited to the amount by which fair value is below amortized cost; and
public business entities to further disaggregate the current disclosure of credit quality indicators in relation to the amortized cost of financing receivables by year of origination.

Table of Contents
For public business entities that file with the SEC, the guidance in ASU 2016-13 is effective for fiscal years beginning after December 15, 2019 (January 1, 2020 for the Bank), and interim periods within those fiscal years. Early adoption was permitted for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The guidance is to be applied on a modified retrospective basis through a cumulative-effect adjustment to retained earnings as of the beginning of the period in which the amendments are adopted. However, entities are required to use a prospective transition approach for debt securities for which an other-than-temporary impairment had been recognized before the date of adoption. The Bank adopted ASU 2016-13 effective January 1, 2020. In conjunction with the adoption of this guidance, the Bank recorded (on January 1, 2020) a cumulative effect adjustment to retained earnings of $2,191,000 and a corresponding increase in the allowance for credit losses on mortgage loans held for portfolio.
Fair Value Measurement Disclosures. On August 28, 2018, the FASB issued ASU 2018-13, "Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement" ("ASU 2018-13"), which modifies the disclosure requirements on fair value measurements in an effort to improve disclosure effectiveness. ASU 2018-13 removes or modifies certain existing disclosure requirements regarding fair value measurements, including a clarification that the measurement uncertainty disclosure associated with recurring Level 3 fair value measurements is intended to communicate information about the uncertainty in measurement as of the reporting date. In addition to the limited removals and modifications, the guidance requires public business entities to disclose: (i) the changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period and (ii) for recurring and nonrecurring fair value measurements categorized within Level 3 of the fair value hierarchy, the range and weighted average of significant unobservable inputs used to develop those fair value measurements (together, the "new disclosure requirements").
The amendments in ASU 2018-13 are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019 (January 1, 2020 for the Bank). The new disclosure requirements and the narrative description of measurement uncertainty are to be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments are to be applied retrospectively to all periods presented upon their effective date. Early adoption is permitted. In addition, an entity is permitted to early adopt any removed or modified disclosures and delay adoption of the additional disclosures until their effective date. The adoption of ASU 2018-13 on January 1, 2020 did not have any impact on the Bank's results of operations or financial condition, nor did it require any additional disclosures.
Implementation Costs Associated with Cloud Computing Arrangements. On August 29, 2018, the FASB issued ASU 2018-15, "Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract" ("ASU 2018-15"), which clarifies the accounting for implementation costs associated with a hosting arrangement that is a service contract. ASU 2018-15 aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). ASU 2018-15 also addresses the term over which these capitalized implementation costs should be expensed. ASU 2018-15 does not affect the accounting for the service element of a hosting arrangement that is a service contract.
For public business entities, ASU 2018-15 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019 (January 1, 2020 for the Bank). Early adoption is permitted, including adoption in any interim period. The guidance is to be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. The adoption of this guidance on January 1, 2020 did not have a material impact on the Bank's results of operations or financial condition.
Reference Rate Reform. On March 12, 2020, the FASB issued ASU 2020-04, "Facilitation of the Effects of Reference Rate Reform on Financial Reporting" ("ASU 2020-04"), which provides optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. ASU 2020-04 provides optional expedients and exceptions for applying U.S. GAAP to transactions affected by reference rate reform if certain criteria are met. These transactions include: (i) contract modifications, (ii) hedging relationships, and (iii) sales or transfers of debt securities classified as held-to-maturity.
ASU 2020-04 is effective from March 12, 2020 through December 31, 2022. An entity may elect to adopt the amendments for contract modifications as of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020, or prospectively from a date within an interim period that includes or is subsequent to March 12, 2020, up to the date that the financial statements are available to be issued. An entity may elect to apply the amendments in ASU 2020-04 to eligible hedging relationships existing as of the beginning of the interim period that includes March 12, 2020 and to new eligible hedging relationships entered into after the beginning of the interim period that includes March 12, 2020 through December 31, 2022. The one-time election to sell, transfer, or both sell and transfer debt securities classified as held-to-maturity may be made at any time after March 12, 2020 but no later than December 31, 2022.
On January 7, 2021, the FASB issued ASU 2021-01, "Reference Rate Reform" ("ASU 2021-01"), which clarifies that an entity may elect to apply the optional expedients and exceptions in ASU 2020-04 for contract modifications and hedge accounting to derivative instruments that use an interest rate for margining, discounting or contract price alignment that is modified as a result of reference rate reform. An entity may elect to apply the amendments in ASU 2021-01 on a full retrospective basis as of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020 or on a prospective basis to new modifications from any date within an interim period that includes or is subsequent to January 7, 2021, up to the date the financial statements are available to be issued. The amendments in ASU 2021-01 do not apply to contract modifications made after December 31, 2022, new hedging relationships entered into after December 31, 2022, or existing hedging relationships evaluated for effectiveness in periods after December 31, 2022, except for hedging relationships

existing as of December 31, 2022 that apply certain optional expedients in which the accounting effects are recorded through the end of the hedging relationship (including periods after December 31, 2022).
In October 2020, the third-party central clearinghouses with which the Bank transacts transitioned to the use of the Secured Overnight Financing Rate ("SOFR") for margining, discounting and contract price alignment. The Bank elected to retroactively apply the optional expedients and exceptions in ASU 2021-01 to its derivative contracts that were affected by these changes.
The Bank expects that it will elect to apply some of the expedients and exceptions provided in ASU 2020-04 relating to contract modifications, hedging relationships, and sales or transfers of held-to-maturity securities; however,securities and it could apply the expedients and exceptions in ASU 2021-01 to additional derivative contracts in the future. However, the Bank has not yet determined the extent to which it will utilize these expedients and exceptions, nor the timing of when the expedients and exceptions will be elected and therefore the impact of the adoption of ASU 2020-04 and ASU 2021-01 on the Bank's financial condition and results of operations ishas not currently determinable.yet been determined.
Troubled Debt Restructuring Relief. On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (the "CARES Act"), was signed into law by the President of the United States. The CARES Act includes provisions that allow optional, temporary relief from accounting for certain modifications of loans that were not more than 30 days past due as of December 31, 2019 as troubled debt restructurings ("TDRs"). Specifically, under the provisions of the CARES Act, a qualifying financial institution may elect to suspend: (1) the requirements under U.S. GAAP for certain loan modifications that would otherwise be categorized as TDRs and (2) any determination that such loan modifications would be considered TDRs, including the related impairment for accounting purposes. The TDR relief provisions of the CARES Act apply to any modification that is related to an economic hardship as a result of the COVID-19 pandemic, including a forbearance arrangement, an interest rate modification, a repayment plan, or any other similar arrangement that defers or delays the payment of principal or interest, that occurs during the period from March 1, 2020 through the earlier of December 31, 2020 or the date that is 60 days after the termination of the national emergency concerning the COVID-19 pandemic. On December 27, 2020, the Consolidated Appropriations Act, 2021 (the "CAA") was signed into law by the President of the United States. The CAA includes provisions that extend the temporary relief provided under the CARES Act to modifications that occur through the earlier of January 1, 2022 or the date that is 60 days after the termination of the national emergency concerning the COVID-19 pandemic.
The Bank has elected to apply the TDR relief provided by the CARES Act.Act (as extended by the CAA). Accordingly, all modifications meeting the provisions of the CARES Act will be excluded from TDR classification, accounting and disclosure. Loan modifications that do not meet the provisions of the CARES Act will continue to be assessed for TDR classification under the Bank’s existing accounting practices. Through June 30, 2020, the Bank did not have any qualifying loan modifications and, therefore,To date, the election to apply the TDR relief provisions of the CARES Act has thus far not had anya material impact on the Bank's financial condition, results of operations or disclosures.

     Prepayment Fees. When a member/borrower prepays an advance, the Bank could suffer lower future income if the principal portion of the prepaid advance is reinvested in lower-yielding assets. To protect against this risk, the Bank generally charges a prepayment fee that makes it financially indifferent to a borrower’s decision to prepay an advance. The Bank records prepayment fees received from members/borrowers on prepaid advances net of any associated hedging adjustments on those

Table of Contents
advances. These fees are reflected as interest income in the statements of income either immediately (as prepayment fees on advances) or over time (as interest income on advances) as further described below. In cases in which the Bank funds a new advance concurrent with or within a short period of time before or after the prepayment of an existing advance and the advance meets the accounting criteria to qualify as a modification of the prepaid advance, the net prepayment fee on the prepaid advance is deferred, recorded in the basis of the modified advance, and amortized into interest income on advances over the life of the modified advance using the level-yield method. During the three and six months ended June 30, 2021, gross advance prepayment fees received from members/borrowers were $2,699,000 and $5,123,000, respectively, of which $653,000 were deferred. During the three and six months ended June 30, 2020, and 2019, gross advance prepayment fees received from members/borrowers were $4,057,000 and $549,000,$6,029,000, respectively, none of which were deferred. During the six months ended June 30, 2020 and 2019, gross advance prepayment fees received from members/borrowers were $6,029,000 and $742,000, respectively, none of which were deferred.

The Bank also offers advances that include a symmetrical prepayment feature which allows a member to prepay an advance at the lower of par value or fair value plus a make-whole amount payable to the Bank. There were no prepayments of symmetrical prepayment advances during the six months ended June 30, 2020. During the three months ended March 31, 2019, a symmetrical prepayment advance with a par value of $5,000,000 was prepaid. The difference by which the par value of the advance exceeded its fair value, less the make-whole amount, totaled $68,000 and was recorded in prepayment fees on advances. There were no prepayments of symmetrical prepayment advances during the three months ended June 30, 2019.

Note 9—Allowance for Credit Losses
As discussed in Note 2, onOn January 1, 2020, the Bank adopted new accounting guidance pertaining to the measurement of credit losses on financial instruments. This guidance replaced the previous incurred loss methodology with an expected credit loss methodology. In conjunction with the adoption of this guidance, the Bank recorded (on January 1, 2020) a cumulative effect adjustment to retained earnings of $2,191,000 and a corresponding increase in the allowance for credit losses on mortgage loans held for portfolio.
As of the balance sheet date, an allowance for credit losses is separately established, if necessary, for each of the Bank’s financial instruments carried at amortized cost, its available-for-salesavailable-for-sale securities and its off-balance sheet credit exposures. Expected credit losses on these financial instruments are recorded through an allowance for credit losses. The allowance for credit losses is the amount necessary to reduce the amortized cost of financial instruments carried at amortized cost to the net amount expected to be collected and the amortized cost of available-for-sale securities to the higher of the security's fair value or the present value of the cash flows expected to be collected from the security. To the extent necessary, an allowance for credit losses for off-balance sheet credit exposures is recorded as a liability. The accounting treatment for credit losses on financing receivables and impairment on investments in periods prior to January 1, 2020 is discussed in the 2019 10-K.

Short-Term Investments. The Bank invests in overnight interest-bearing deposits, overnight Federal Funds sold and overnight securities soldpurchased under agreements to repurchase.resell. These investments provide short-term liquidity and are carried at amortized cost. Accrued interest is recorded separately on the statement of condition (see Note 8). At June 30, 2020, allAll investments in Federal Funds sold, interest-bearing deposits and securities purchased under agreements to resell that were outstanding at June 30, 2021 were repaid according to thetheir contractual terms. Accordingly, no allowance for credit losses was recorded on these assets at June 30, 2020.2021.
Long-Term Investments. The Bank evaluates its available-for-sale securities for impairment by comparing the security's fair value to its amortized cost. Impairment exists when the fair value of the investment is less than its amortized cost (i.e., when the security is in an unrealized loss position).The. The Bank evaluates each impaired security to determine whether the impairment is due to credit losses. Held-to-maturity securities are evaluated for impairment on a pooled basis, unless an individual assessment is deemed necessary because the securities do not contain similar risk characteristics. Accrued interest is recorded separately on the statement of condition.
At June 30, 2020,2021, the gross unrealized losses on the Bank’s available-for-sale securities were $120,440,000,$7,800,000, all of which related to securities that are either guaranteed by the U.S. government or issued and guaranteed by GSEs. At June 30, 2020,2021, the gross unrealized losses on the Bank’s held-to-maturity securities (computed as the difference between the amortized cost and the fair value of the securities) were $4,774,000,$1,597,000, of which $1,440,000 were attributable to MBS that are issued and guaranteed by GSEs, $123,000 were attributable to securities issued by a state housing agency and $3,211,000 were$1,128,000 was attributable to its holdings of non-agency (i.e., private-label) residential MBS ("RMBS"). and $469,000 was attributable to a security issued by a state housing agency. At that same date, there were no unrealized losses on any of the Bank's holdings of U.S. government-guaranteed debentures or GSE RMBS.
Government-Guaranteed and GSE Investments. As of June 30, 2020,2021, the U.S. government and the issuers of the Bank’s holdings of GSE debentures, GSE commercial MBS ("CMBS") and GSE RMBS were rated triple-A by Moody’s Investors Service (“Moody’s”) and AA+ by S&P Global Ratings (“S&P”). Through June 30, 2020,2021, the Bank has not experienced any defaults on its government-guaranteed debentures or GSE RMBS and it has experienced only one default on its GSE CMBS, or GSE RMBS.which default occurred in 2020. In the event of a default, the guarantor is required to repurchase the security at its par value and thus the Bank's exposure is limited to the amount of any unamortized premiums and/or positive fair value hedge accounting adjustments included in the amortized cost basis of the investment. Based upon the Bank's assessment of the strength of the government guaranty, the Bank expects that the amounts to be collected on its holdings of U.S. government-guaranteed debentures will not be less than the Bank's amortized cost bases in these investments. Based upon the Bank's assessment of the creditworthiness of the issuers of the GSE debentures that were in an unrealized loss position at June 30, 20202021 and the credit ratings assigned by Moody's and S&P, the Bank expects that these debentures would not be settled at an amount less than the Bank's amortized cost bases in the investments. In addition, based upon the Bank's assessment of the strength of the GSEs' guarantees of the Bank's holdings of GSE CMBS and GSE RMBS and the credit ratings assigned by Moody's and S&P, the Bank expects that the amounts to be collected on its holdings of GSE MBS will not be less than the Bank’s amortized cost bases in these investments (or, in the rare circumstance of a default, the amount to be collected would not be expected to be significantly less than the Bank’s amortized cost basis in the investment). The Bank does not intend to sell the investments and it is not more likely than not that the Bank will be required to sell the investments before recovery of their amortized cost bases. Because the current market value deficits associated with the Bank's available-for-sale securities are not attributable to credit quality, and because the amount expected to be collected on its held-to-maturity securities is not less than the amortized cost of these investments, the Bank has determined that the credit losses on its GSE investments, if any, would be insignificant and, therefore, the Bank did not provide an allowance for credit losses is not necessary on any of its government-guaranteed or GSEthese investments at June 30, 2020.2021.
State Housing Agency Debentures. As of June 30, 2020,2021, the Bank's holdings of state housing agency bonds are rated triple-A by both Moody's and S&P. The Bank has not experienced any defaults on its state housing agency debentures, nor does it expect to experience any defaults on these securities. Based upon the Bank's assessment of the creditworthiness of the state housing agency and the credit ratings assigned by Moody's and S&P, the Bank expects that the amounts to be collected on its holdings of state housing agency debentures will not be less than the amortized cost basis of these investments. Because the Bank does not intend to sell the investments and it is not more likely than not that the Bank will be required to sell the

investments before recovery of their amortized cost bases, the Bank does not consider an allowance for credit losses on its state housing debentures to be necessary at June 30, 2020.2021.
Non-Agency RMBS. As of June 30, 2020,2021, 5 of the Bank's non-agency RMBS with an aggregate amortized cost of $11,473,000$8,855,000 were rated investment grade (i.e., triple-B or higher by Moody's and/or S&P), 16 non-agency RMBS with an aggregate amortized cost of $44,657,000$33,362,000 were rated below investment grade and 1 non-agency RMBS with an amortized cost of $75,000$44,000 was unrated. In periods prior to 2017, 15 of the non-agency RMBS that were rated below investment grade at June 30, 20202021 had been determined to be other-than-temporarily impaired. At June 30, 20202021 and December 31, 2019,2020, the amortized cost of the Bank's non-agency RMBS included credit losses of $6,509,000$6,172,000 and $6,765,000,$6,293,000, respectively, on these previously impaired securities.
Because the ultimate receipt of contractual payments on the Bank’s non-agency RMBS will depend upon the credit and prepayment performance of the underlying loans and the credit enhancements for the senior securities owned by the Bank, the Bank closely monitors these investments in an effort to determine whether the credit enhancement associated with each security is sufficient to protect against potential losses of principal and interest on the underlying mortgage loans. The credit enhancement for each of the Bank’s non-agency RMBS is provided by a senior/subordinate structure, and none of the securities
17

Table of Contents```
owned by the Bank are insured by third-party bond insurers. More specifically, each of the Bank’s non-agency RMBS represents a single security class within a securitization that has multiple classes of securities. Each security class has a distinct claim on the cash flows from the underlying mortgage loans, with the subordinate securities having a junior claim relative to the more senior securities. The Bank’s non-agency RMBS have a senior claim on the cash flows from the underlying mortgage loans.
To assess whether an allowance for credit losses was needed on its 22 non-agency RMBS holdings, the Bank considered the results of the cash flow analyses that it performed for each security as of December 31, 2019 under both a best estimate scenario and a more stressful housing price scenario. The analyses were performed using two third-party models. The first model considered borrower characteristics and the particular attributes of the loans underlying the Bank’s securities, in conjunction with assumptions about future changes in home prices and interest rates, to project prepayments, defaults and loss severities.
The month-by-month projections of future loan performance derived from the first model, which reflected projected prepayments, defaults and loss severities under each scenario, were then input into a second model that allocated the projected loan level cash flows and losses to the various security classes in the securitization structure in accordance with its prescribed cash flow and loss allocation rules. In a securitization in which the credit enhancement for the senior securities is derived from the presence of subordinate securities, losses are generally allocated first to the subordinate securities until their principal balance is reduced to zero.
At June 30, 2020,2021, the Bank considered the potential impact that recent changes in economic and housing market conditions could have on the collectibility of these securities relative to the assumptions that were used in the cash flow projections under the more stressful housing price scenario referred to above underlying its evaluation as of December 31, 2020 to determine whether it expected to incur any additional credit losses on these securities. Based on the results of these cash flow analyses,that evaluation, the payment status of the securities and the considerations regarding the potential impact that the COVID-19 pandemicrecent changes in economic and housing market conditions could have on the securities' cash flows, the Bank determined it is likely that it will fully recover the remaining amortized cost bases of all of its non-agency RMBS. Because the Bank does not intend to sell the investments and it is not more likely than not that the Bank will be required to sell the investments before recovery of their remaining amortized cost bases, no allowance for credit losses on the Bank's non-agency RMBS was deemed to be necessary at June 30, 2020.2021.
Standby Bond Purchase Agreements. The Bank has entered into standby bond purchase agreements with a state housing finance agency within its district whereby, for a fee, the Bank agrees to serve as a standby liquidity provider. If required, the Bank will purchase and hold the housing finance agency's bonds until the designated marketing agent can find a suitable investor or the housing finance agency repurchases the bonds according to a schedule established by the agreement. To date, the Bank has never been required to purchase a bond under its standby bond purchase agreements. In addition, the agreements contain provisions that allow the Bank to terminate the agreement if the housing finance agency's credit rating, or the rating of the bonds underlying the agreements, decline to a level below investment grade. Based on these provisions, the high credit quality of the housing finance agency and the unlikelihood that the Bank will be required to repurchase the bonds, a reservean allowance for credit losses on standby bond purchase agreements was not considered necessary at June 30, 2020.2021.
Financing Receivables. A portfolio segment is defined as the level at which an entity develops and documents a systematic method for determining its allowance for credit losses on financing receivables which, for the Bank, includes off-balance sheet credit exposures to members. The Bank has developed and documented a systematic methodology for determining an allowance for credit losses for the following portfolio segments: (1) advances and other extensions of credit to members/borrowers, collectively referred to as “extensions of credit to members”; (2) government-guaranteed/insured mortgage loans held for portfolio; and (3) conventional mortgage loans held for portfolio.
Classes of financing receivables are generally a disaggregation of a portfolio segment and are determined on the basis of their initial measurement attribute, the risk characteristics of the financing receivable and an entity’s method for monitoring and assessing credit risk. Because the credit risk arising from the Bank’s financing receivables is assessed and measured at the portfolio segment level, the Bank does not have separate classes of financing receivables within each of its portfolio segments.
During the six months ended June 30, 2020 and 2019, there were no significant purchases or sales of financing receivables, nor were any financing receivables reclassified to held for sale.
    Advances and Other Extensions of Credit to Members. In accordance with federal statutes, including the Federal Home Loan Bank Act of 1932, as amended (the “FHLB Act”), the Bank lends to financial institutions within its five-state district that are involved in housing finance. The FHLB Act requires the Bank to obtain and maintain sufficient collateral for advances and other extensions of credit to protect against losses. The Bank makes advances and otherwise extends credit only against eligible collateral, as defined by regulation. To ensure the value of collateral pledged to the Bank is sufficient to secure its advances and other extensions of credit, the Bank applies various haircuts, or discounts, to the collateral to determine the value against which borrowers may borrow. As additional security, the Bank has a statutory lien on each borrower’s capital stock in the Bank. The
18

Bank has procedures in place for validating the reasonableness of its collateral valuations. In addition, collateral verifications and on-site reviews are performed based on the risk profile of the borrower.
17

Table of Contents
On at least a quarterly basis, the Bank evaluates all outstanding extensions of credit to members/borrowers for potential credit losses. These evaluations include a review of: (1) the amount, type and performance of collateral available to secure the outstanding obligations; (2) metrics that may be indicative of changes in the financial condition and general creditworthiness of the member/borrower; and (3) the payment status of the obligations. Any outstanding extensions of credit that exhibit a potential credit weakness that could jeopardize the full collection of the outstanding obligations would be classified as substandard, doubtful or loss. The Bank did not have any advances or other extensions of credit to members/borrowers that were classified as substandard, doubtful or loss at June 30, 20202021 or December 31, 2019.2020.
The Bank considers the amount, type and performance of collateral to be the primary indicator of credit quality with respect to its extensions of credit to members/borrowers. At June 30, 20202021 and December 31, 2019,2020, the Bank had rights to collateral on a borrower-by-borrower basis with an estimated value in excess of each borrower’s outstanding extensions of credit.
The Bank continues to evaluate and, as necessary, modify its credit extension and collateral policies based on market conditions. At June 30, 20202021 and December 31, 2019,2020, the Bank did not have any advances that were past due or on nonaccrual status, or considered impaired.status. There have been no troubled debt restructurings related to advances.
The Bank has never experienced a credit loss on an advance or any other extension of credit to a member/borrower and, based on its credit extension and collateral policies, management currently does not anticipate any credit losses on its extensions of credit to members/borrowers. Accordingly, the Bank has not provided any allowance for credit losses on advances, nor has it recorded any liabilities to reflect an allowance for credit losses related to its off-balance sheet credit exposures to members.
 Mortgage Loans — Government-guaranteed or government-insured. The Bank’s government-guaranteed or government-insured fixed-rate mortgage loans are guaranteed or insured by the Federal Housing Administration or the Department of Veterans Affairs and were acquired through the MPF program (as more fully described in the Bank’s 20192020 10-K) in periods prior to 2004. Any losses from these loans are expected to be recovered from those entities. Any losses from these loans that are not recovered from those entities are absorbed by the servicers. Therefore, the Bank has not established an allowance for credit losses on government-guaranteed or government-insured mortgage loans. Government-guaranteed or government-insured loans are not placed on nonaccrual status.
Mortgage Loans — Conventional Mortgage Loans. The Bank’s conventional mortgage loans have also been acquired through the MPF program. The allowance for credit losses on conventional mortgage loans is determined by an analysis that includes consideration of various data such as past performance, current performance, projected performance, loan portfolio characteristics, collateral-related characteristics, prevailing economic conditions and reasonable and supportable forecasts of expected economic conditions. The allowance for credit losses on conventional mortgage loans also factors in the credit enhancement under the MPF program. AnyThe Bank does not record an allowance for credit losses that are expected to be recovered from the credit enhancements are not reserved as part of the Bank’s allowance for credit losses.enhancements.
The Bank places a conventional mortgage loan on nonaccrual status when the collection of the contractual principal or interest is 90 days or more past due. When a mortgage loan is placed on nonaccrual status, accrued but uncollected interest is reversed against interest income. The Bank records cash payments received on nonaccrual loans as a reduction of principal. A loan on nonaccrual status is restored to accrual status when none of its contractual principal and interest is due and unpaid, and the Bank expects repayment of the remaining contractual interest and principal. At June 30, 2021 and December 31, 2020, interest payments received on nonaccrual loans and recorded as a reduction of principal totaled $3,092,000 and $1,555,000, respectively.
Collateral-dependent mortgage loans that are on nonaccrual status90 days or more past due are measuredevaluated for impairmentcredit losses an individual basis based on the fair value of the underlying mortgaged property less estimated selling costs. Loans are considered collateral-dependent if repayment is expected to be provided solely by the sale of the underlying property; that is, there is no other available and reliable source of repayment. A collateral-dependent loan is impaired if the fair value of the underlying collateral less estimated selling costs is less than the amortized cost of the loan. Interest income on impaired loans is recognized in the same manner as it is for nonaccrual loans noted above.
The Bank evaluates whether to record a charge-off on a conventional mortgage loan when the loan becomes 180 days or more past due or upon the occurrence of a confirming event, whichever occurs first. Confirming events include, but are not limited to, the occurrence of foreclosure or notification of a claim against any of the credit enhancements. A charge-off is recorded if the amount expected to be collected on the loan is less than its amortized cost.
As discussed in Note 2, the CARES Act provides temporary relief from the accounting and reporting requirements for certain loan modifications related to COVID-19 that would otherwise be categorized as a TDR. Eligible mortgage loans that are current under the modified terms of the loan agreements are returned to accrual status as long as the Bank expects repayment of the remaining contractual principal and interest. As of June 30, 2020, 2021, the Bank had not entered into any qualifying loan modifications.modifications on loans with an aggregate unpaid principal balance of approximately $13,328,000. These loan modifications allowed the borrowers to defer past due principal and interest payments until the earlier of the date on which the loan is prepaid or the end of the loan term. In aggregate, the amounts deferred were insignificant.

The servicers of the Bank's mortgage loans may grant a forbearance period to borrowers who request forbearance as a result of difficulties relating to COVID-19 regardless of the status of the loan at the time of the request. During the forbearance period, the Bank accounts for these loans in the same manner as it accounts for any other past due loans whether the forbearance arrangement is formal or informal. The accrual status of mortgage loans in forbearance is determined by the past due status of the loan as the legal terms of the loan agreement remain unchanged during this period.
The Bank considers the key credit quality indicator for conventional mortgage loans to be the payment status of each loan. The table below summarizes the amortized cost (excluding accrued interest receivable) by payment status for mortgage loans at June 30, 20202021 and the recorded investment (which includes accrued interest receivable) by payment status for mortgage loans at December 31, 20192020 (dollars in thousands).

Note 10—Consolidated Obligations
Consolidated obligations are the joint and several obligations of the FHLBanks and consist of consolidated obligation bonds and discount notes. Consolidated obligations are backed only by the financial resources of the 11 FHLBanks. Consolidated obligations are not obligations of, nor are they guaranteed by, the U.S. government. The FHLBanks issue consolidated obligations through the Office of Finance as their agent. In connection with each debt issuance, one or more of the FHLBanks specifies the amount of debt it wants issued on its behalf; the Bank receives the proceeds of only the debt issued on its behalf and records on its statements of condition only that portion of the consolidated obligations for which it has received the proceeds. Consolidated obligation bonds are issued primarily to raise intermediate- and long-term funds for the FHLBanks and are not subject to any statutory or regulatory limits on maturity. Consolidated obligation discount notes are issued to raise short-term funds and have maturities of one year or less. These notes are issued at a price that is less than their face amount and are redeemed at par value when they mature. For additional information regarding the FHLBanks’ joint and several liability on consolidated obligations, see Note 17.
The par amounts of the 11 FHLBanks’ outstanding consolidated obligations, including consolidated obligations held as investments by other FHLBanks, were approximately $916$667 billion and $1.026 trillion$747 billion at June 30, 20202021 and December 31, 2019,2020, respectively. The Bank was the primary obligor on $68.5$53.0 billion and $70.1$59.2 billion (at par value), respectively, of these consolidated obligations.

Note 12—Assets and Liabilities Subject to Offsetting
The Bank hasenters into derivatives and securities purchased under agreements to resell that are subject to enforceable master netting agreements or similar arrangements. For purposes of reporting derivative assets and derivative liabilities, the Bank offsets the fair value amounts recognized for derivative instruments (including the right to reclaim cash collateral and the obligation to return cash collateral) where a legally enforceable right of setoff exists. The Bank did not have any liabilities that were eligible to offset its securities purchased under agreements to resell (i.e., securities sold under agreements to repurchase) as of June 30, 20202021 or December 31, 2019.2020.
The Bank's derivative transactions are executed either bilaterally or, if required, cleared through a third-party central clearinghouse. The Bank has entered into master agreements with each of its bilateral derivative counterparties that provide for the netting of all transactions with each of these counterparties. Under its master agreements with its non-member bilateral derivative counterparties, collateral is delivered (or returned) daily when certain thresholds (ranging from $50,000 to $500,000) are met. The Bank offsets the fair value amounts recognized for bilaterally traded derivatives executed with the same counterparty, including any cash collateral remitted to or received from the counterparty. When entering into derivative transactions with its members, the Bank requires the member to post eligible collateral in an amount equal to the sum of the net market value of the member’s derivative transactions with the Bank (if the value is positive to the Bank) plus a percentage of the notional amount of any interest rate swaps, with market values determined on at least a monthly basis. Eligible collateral for derivative transactions with members consists of collateral that is eligible to secure advances and other obligations under the member's Advances and Security Agreement with the Bank. The Bank is not required to pledge collateral to its members to secure derivative positions.
For cleared derivatives, all transactions with each clearing member of each clearinghouse are netted pursuant to legally enforceable setoff rights. Cleared derivatives are subject to initial and variation margin requirements established by the clearinghouse and its clearing members. Unlike bilateral derivatives, variation margin payments on cleared derivatives are legally characterized as settlements on the contracts. Initial and variation margin is typically delivered/paid (or returned/received) daily and is not subject to any maximum unsecured thresholds. The Bank offsets the fair value amounts recognized for cleared derivatives transacted with each clearing member of each clearinghouse (which fair value amounts include variation margin paid or received) and any cash collateral pledged or received.

Note 13—Derivatives and Hedging Activities
     Hedging Activities. As a financial intermediary, the Bank is exposed to interest rate risk. This risk arises from a variety of financial instruments that the Bank enters into on a regular basis in the normal course of its business. The Bank enters into interest rate swap, swaption cap and forward ratecap agreements (collectively, interest rate exchange agreements) to manage its exposure to changes in interest rates. The Bank may use these instruments to adjust the effective maturity, repricing frequency, or option characteristics of financial instruments to achieve risk management objectives. In addition, the Bank may use these instruments to hedge the variable cash flows associated with forecasted transactions. The Bank has not entered into any credit default swaps or foreign exchange-related derivatives and, as of June 30, 2020, it was not a party to any forward rate agreements.derivatives.
The Bank uses interest rate exchange agreements in three ways: (1) by designating the agreement as a fair value hedge of a specific financial instrument or firm commitment; (2) by designating the agreement as a cash flow hedge of a forecasted transaction; or (3) by designating the agreement as a hedge of some other defined risk (referred to as an “economic hedge”). For example, the Bank uses interest rate exchange agreements in its overall interest rate risk management activities to adjust the interest rate sensitivity of consolidated obligations to approximate more closely the interest rate sensitivity of its assets (both advances and investments), and/or to adjust the interest rate sensitivity of advances or investments to approximate more closely the interest rate sensitivity of its liabilities. In addition to using interest rate exchange agreements to manage mismatches between the coupon features of its assets and liabilities, the Bank also uses interest rate exchange agreements to, among other things, manage embedded options in assets and liabilities, to preserve the market value of existing assets and liabilities, to hedge the duration risk of prepayable instruments, to hedge the variable cash flows associated with forecasted transactions, to offset interest rate exchange agreements entered into with members (the Bank serves as an intermediary in these transactions), and to reduce funding costs.
The Bank, consistent with Finance Agency regulations, enters into interest rate exchange agreements only to reduce potential market risk exposures inherent in otherwise unhedged assets and liabilities or anticipated transactions, or to act as an intermediary between its members and the Bank’s non-member derivative counterparties. The Bank is not a derivatives dealer and it does not trade derivatives for short-term profit.
At inception, the Bank formally documents the relationships between derivatives designated as hedging instruments and their hedged items, its risk management objectives and strategies for undertaking the hedge transactions, and its method for assessing the effectiveness of the hedging relationships. For fair value hedges, this process includes linking the derivatives to: (1) specific assets and liabilities on the statements of condition or (2) firm commitments. For cash flow hedges, this process includes linking the derivatives to forecasted transactions. The Bank also formally assesses (both at the inception of the hedging relationship and on a monthly basis thereafter) whether the derivatives that are used in hedging transactions have been highly effective in offsetting changes in the fair value of hedged items or the cash flows associated with forecasted transactions and whether those derivatives may be expected to remain highly effective in future periods. The Bank uses regression analyses to assess the effectiveness of its hedges.
     Investment Securities and Mortgage Loans Held for Portfolio — The Bank has invested in agency and non-agency MBS and residential mortgage loans. The interest rate and prepayment risk associated with these investments is managed through consolidated obligations and/or derivatives. The Bank may manage prepayment and duration risk presented by some of these investments with either callable and/or non-callable consolidated obligations and/or interest rate exchange agreements, including interest rate swaps, swaptions and caps.
A substantial portion of the Bank’s held-to-maturity securities are variable-rate MBS that include caps that would limit the variable-rate coupons if short-term interest rates rise dramatically. To hedge a portion of the potential cap risk embedded in these securities, the Bank entered into interest rate cap agreements, only one of which remained outstanding at June 30, 2020.2021. These derivatives are treated as economic hedges.
All of the Bank's available-for-sale securities are fixed-rate agency and other highly rated debentures and agency CMBS. To hedge the interest rate risk associated with these fixed-rate investment securities, the Bank has entered into fixed-for-floating interest rate exchange agreements, which are designated as fair value hedges.
The Bank's trading securities include both fixed-rate and variable-rate U.S. Treasury Notes. To convert most of its fixed-rate U.S. Treasury Notes to a short-term floating rate, the Bank has, at times, entered into fixed-for-floating interest rate exchange agreements that arewere primarily indexed to the overnight index swap ("OIS") rate. These derivatives arewere treated as economic hedges.
The interest rate swaps and swaptions that are used by the Bank to hedge the risks associated with its mortgage loan portfolio are treated as economic hedges.
Advances — The Bank issues both fixed-rate and variable-rate advances. When deemed appropriate, the Bank uses interest rate exchange agreements to adjust the interest rate sensitivity of its fixed-rate advances to approximate more closely the
2524

Table of Contents```
interest rate sensitivity of its liabilities. With issuances of putable advances, the Bank purchases from the member a put option that enables the Bank to terminate a fixed-rate advance on specified future dates. This embedded option is clearly and closely related to the host advance contract. The Bank typically hedges a putable advance by entering into a cancelable interest rate exchange agreement where the Bank pays a fixed-rate coupon and receives a variable-rate coupon, and sells an option to cancel the swap to the swap counterparty. This type of hedge is treated as a fair value hedge. The swap counterparty can cancel the interest rate exchange agreement on the call date and the Bank can cancel the putable advance and offer, subject to certain conditions, replacement funding at prevailing market rates.
From time to time, a small portion of the Bank’s variable-rate advances aremay be subject to interest rate caps that would limit the variable-rate coupons if short-term interest rates rise above a predetermined level. To hedge the cap risk embedded in these advances, the Bank will generally enter into interest rate cap agreements. This type of hedge is treated as a fair value hedge.
The Bank may hedge a firm commitment for a forward-starting advance through the use of an interest rate swap. In this case, the swap will function as the hedging instrument for both the firm commitment and the subsequent advance. The carrying value of the firm commitment will be included in the basis of the advance at the time the commitment is terminated and the advance is issued. The basis adjustment will then be amortized into interest income over the life of the advance.
The Bank enters into optional advance commitments with its members. In an optional advance commitment, the Bank sells an option to the member that provides the member with the right to increase the amount of an existing advance at a specified fixed rate and term on a specified future date, provided the member has satisfied all of the customary requirements for such advance. This embedded option is clearly and closely related to the host contract. The Bank may hedge an optional advance commitment through the use of an interest rate swaption. In this case, the swaption will function as the hedging instrument for both the commitment and, if the option is exercised by the member, the subsequent advance. These swaptions are treated as fair value hedges.
 Consolidated Obligations While consolidated obligations are the joint and several obligations of the FHLBanks, each FHLBank is the primary obligor for the consolidated obligations it has issued or assumed from another FHLBank. The Bank generally enters into derivative contracts to hedge the interest rate risk associated with its specific debt issuances.
To manage the interest rate risk of certain of its consolidated obligations, the Bank will match the cash outflow on a consolidated obligation with the cash inflow of an interest rate exchange agreement. With issuances of fixed-rate consolidated obligation bonds, the Bank typically enters into a matching interest rate exchange agreement in which the counterparty pays fixed cash flows to the Bank that are designed to mirror in timing and amount the cash outflows the Bank pays on the consolidated obligation. In this transaction, the Bank pays a variable cash flow that closely matches the interest payments it receives on short-term or variable-rate assets. These transactions are treated as fair value hedges. On occasion, the Bank may enter into fixed-for-floating interest rate exchange agreements to hedge the interest rate risk associated with certain of its consolidated obligation discount notes. The derivatives associated with the Bank’s fair value discount note hedging are indexed to the OIS rate and are treated as economic hedges. The Bank may also use interest rate exchange agreements to convert variable-rate consolidated obligation bonds from one index rate to another index rate. These transactions are treated as economic hedges.
The Bank has not issued consolidated obligations denominated in currencies other than U.S. dollars.
Forecasted Issuances of Consolidated Obligations The Bank uses derivatives to hedge the variability of cash flows over a specified period of time as a result of the forecasted issuances and maturities of short-term, fixed-rate instruments, such as three-month consolidated obligation discount notes. Although each short-term consolidated obligation discount note has a fixed rate of interest, a portfolio of rolling consolidated obligation discount notes effectively has a variable interest rate. The variable cash flows associated with these liabilities are converted to fixed-rate cash flows by entering into receive-variable, pay-fixed interest rate swaps. The maturity dates of the cash flow streams are closely matched to the interest rate reset dates of the derivatives. These derivatives are treated as cash flow hedges.
Balance Sheet Management — From time to time, the Bank may enter into interest rate basis swaps to reduce its exposure to changing spreads between different interest rate indices. In addition, to reduce its exposure to reset risk, the Bank may occasionally enter into forward rate agreements. These derivatives are treated as economic hedges.
Intermediation — The Bank offers interest rate swaps, caps and floors to its members to assist them in meeting their hedging needs. In these transactions, the Bank acts as an intermediary for its members by entering into an interest rate exchange agreement with a member and then entering into an offsetting interest rate exchange agreement with one of the Bank’s approved derivative counterparties. All interest rate exchange agreements related to the Bank’s intermediary activities with its members are accounted for as economic hedges.
Other — From time to time, the Bank may enter into derivatives to hedge risks to its earnings that are not directly linked to specific assets, liabilities or forecasted transactions. These derivatives are treated as economic hedges.

     Accounting for Derivatives and Hedging Activities. The Bank accounts for derivatives and hedging activities in accordance with the guidance in Topic 815 of the FASB’s Accounting Standards Codification (“ASC”) entitled “Derivatives and Hedging” (“ASC 815”). All derivatives are recognized on the statements of condition at their fair values, including accrued interest receivable and payable. For purposes of reporting derivative assets and derivative liabilities, the Bank offsets the fair value amounts recognized for derivative instruments (including the right to reclaim cash collateral and the obligation to return cash collateral) where a legally enforceable right of setoff exists.
Changes in the fair value of a derivative that is effective as — and that is designated and qualifies as — a fair value hedge, along with changes in the fair value of the hedged asset or liability that are attributable to the hedged risk (including changes that reflect gains or losses on firm commitments), are recorded in current period earnings. The application of hedge accounting generally requires the Bank to evaluate the effectiveness of the fair value hedging relationships on an ongoing basis and to calculate the changes in fair value of the derivatives and related hedged items independently. This is commonly known as the “long-haul” method of hedge accounting. Transactions that meet more stringent criteria qualify for the “shortcut” method of hedge accounting in which an assumption can be made that the change in fair value of a hedged item exactly offsets the change in value of the related derivative. The Bank considers hedges of committed advances to be eligible for the shortcut method of accounting as long as the settlement of the committed advance occurs within the shortest period possible for that type of
25

Table of Contents
instrument based on market settlement conventions, the fair value of the swap is zero at the inception of the hedging relationship, and the transaction meets all of the other criteria for shortcut accounting specified in ASC 815.U.S. GAAP. The Bank has defined the market settlement convention to be five business days or less for advances.
Fair value hedge ineffectiveness (which represents the amount by which the change in the fair value of the derivative differs from the change in the fair value of the hedged item attributable to the hedged risk) and the net interest income/expense associated with that derivative are recorded in the same line item as the earnings effect of the hedged item (that is, interest income on advances, interest income on available-for-sale securities or interest expense on consolidated obligation bonds, as appropriate).
Changes in the fair value of a derivative that is designated and qualifies as a cash flow hedge are recorded in accumulated other comprehensive income ("AOCI") until earnings are affected by the variability of the cash flows of the hedged transaction, at which time these amounts are reclassified from AOCI to the income statement line where the earnings effect of the hedged item is reported (e.g., interest expense on consolidated obligation discount notes).
An economic hedge is defined as a derivative hedging specific or non-specific assets or liabilities that does not qualify or was not designated for hedge accounting, under ASC 815, but is an acceptable hedging strategy under the Bank’s Enterprise Market Risk Management Policy. These hedging strategies also comply with Finance Agency regulatory requirements prohibiting speculative derivative transactions. An economic hedge by definition introduces the potential for earnings variability as changes in the fair value of a derivative designated as an economic hedge are recorded in current period earnings with no offsetting fair value adjustment to an asset or liability. Both the net interest income/expense and the fair value changes associated with derivatives in economic hedging relationships are recorded in other income (loss) as “net gains (losses) on derivatives and hedging activities.”
The Bank records the changes in fair value of all derivatives (and, in the case of fair value hedges, the hedged items) beginning on the trade date.
Cash flows associated with all derivatives are reported as cash flows from operating activities in the statements of cash flows, unless the derivative contains an other-than-insignificant financing element, in which case its cash flows are reported as cash flows from financing activities.
The Bank may issue debt, make advances, or purchase financial instruments in which a derivative instrument is “embedded” and the financial instrument that embodies the embedded derivative instrument is not remeasured at fair value with changes in fair value reported in earnings as they occur. Upon execution of these transactions, the Bank assesses whether the economic characteristics of the embedded derivative are clearly and closely related to the economic characteristics of the remaining component of the financial instrument (i.e., 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. When it is determined that (1) the embedded derivative possesses economic characteristics that are not clearly and closely related to the economic characteristics of the host contract and (2) a separate, stand-alone instrument with the same terms would qualify as a derivative instrument, the embedded derivative is separated from the host contract, carried at fair value, and designated as either (1) a hedging instrument in a fair value hedge or (2) a stand-alone derivative instrument pursuant to an economic hedge. However, if the entire contract were to be measured at fair value, with changes in fair value reported in current earnings, or if the Bank could not reliably identify and measure the embedded derivative for purposes of separating that derivative from its host contract, the entire contract would be carried on the statement of condition at fair value and no portion of the contract would be separately accounted for as a derivative.

The Bank discontinues hedge accounting prospectively when: (1) management determines that the derivative is no longer highly effective in offsetting changes in the fair value or cash flows of a hedged item; (2) the derivative and/or the hedged item expires or is sold, terminated, or exercised; (3) it is no longer probable that a forecasted transaction will occur within the originally specified time frame; (4) a hedged firm commitment no longer meets the definition of a firm commitment; or (5) management determines that designating the derivative as a hedging instrument in accordance with ASC 815 is no longer appropriate.
In all cases in which hedge accounting is discontinued and the derivative remains outstanding, the Bank will carry the derivative at its fair value on the statement of condition, recognizing any additional changes in the fair value of the derivative in current period earnings as a component of "net gains (losses) on derivatives and hedging activities."
When fair value hedge accounting for a specific derivative is discontinued due to the Bank’s determination that such derivative no longer qualifies for hedge accounting treatment or because the derivative is terminated, the Bank will cease to adjust the hedged asset or liability for changes in fair value and amortize the cumulative basis adjustment on the formerly hedged item into earnings over its remaining term using the level-yield method. The amortization is recorded in the same line item as the earnings effect of the formerly hedged item.
When hedge accounting is discontinued because the hedged item no longer meets the definition of a firm commitment, the Bank continues to carry the derivative on the statement of condition at its fair value, removing from the statement of condition

any asset or liability that was recorded to recognize the firm commitment and recording it as a gain or loss in current period earnings.
When cash flow hedge accounting for a specific derivative is discontinued due to the Bank's determination that such derivative no longer qualifies for hedge accounting treatment or because the derivative is terminated, the Bank will reclassify the cumulative fair value gains or losses recorded in AOCI as of the discontinuance date from AOCI into earnings when earnings are affected by the original forecasted transaction. If the Bank expects at any time that continued reporting of a net loss in AOCI would lead to recognizing a net loss on the combination of the hedging instrument and hedged transaction in one or more future periods, the amount that is not expected to be recovered is immediately reclassified to earnings. These items are recorded in the same income statement line where the earnings effect of the hedged item is reported.
In cases where the cash flow hedge is discontinued because the forecasted transaction is no longer probable (i.e., the forecasted transaction will not occur in the originally expected period or within an additional two-month period of time thereafter), any fair value gains or losses recorded in AOCI as of the determination date are immediately reclassified to earnings as a component of "net gains (losses) on derivatives and hedging activities."

For the three and six months ended June 30, 20202021 and 2019,2020, there were no amounts reclassified from AOCI into earnings as a result of the discontinuance of cash flow hedges because the original forecasted transactions occurred by the end of the originally specified time periods or within two-month periods thereafter. At June 30, 2020, $21,201,0002021, $22,248,000 of deferred net losses on derivative instruments in AOCI are expected to be reclassified to earnings during the next 12 months. At June 30, 2020,that same date, the maximum length of time over which the Bank is hedging its exposure to the variability in future cash flows for forecasted transactions is 9.68.6 years.

Credit Risk Related to Derivatives. The Bank is subject to credit risk due to the risk of nonperformance by counterparties to its derivative agreements. The Bank manages derivative counterparty credit risk through the use of master netting agreements or other similar collateral exchange arrangements, credit analysis, and adherence to the requirements set forth in the Bank’s Enterprise Market Risk Management Policy, Enterprise Credit Risk Management Policy, and Finance Agency regulations. The majorityApproximately 46 percent of the Bank's derivative contracts (based on notional value) have been cleared through third-party central clearinghouses (as of June 30, 2020,2021, the notional balance of cleared transactions outstanding totaled $31.8$23.5 billion). With cleared transactions, the Bank is exposed to credit risk in the event that the clearinghouse or the clearing member fails to meet its obligations to the Bank. The remainder of the Bank's derivative contracts have been transacted bilaterally with large financial institutions under master netting agreements or, to a much lesser extent, with member institutions (as of June 30, 2020,2021, the notional balance of outstanding transactions with non-member bilateral counterparties and member counterparties totaled $14.9$27.7 billion and $0.1 billion, respectively). Some of these institutions (or their affiliates) buy, sell, and distribute consolidated obligations.

The notional amount of the Bank's interest rate exchange agreements does not reflect its credit risk exposure, which is much less than the notional amount. The Bank's net credit risk exposure is based on the current estimated cost, on a present value basis, of replacing at current market rates all interest rate exchange agreements with individual counterparties, if those counterparties were to default, after taking into account the value of any cash and/or securities collateral held or remitted by the Bank. For counterparties with which the Bank is in a net gain position, the Bank has credit exposure when the collateral it is holding (if any) has a value less than the amount of the gain. For counterparties with which the Bank is in a net loss position, the Bank has credit exposure when it has delivered collateral with a value greater than the amount of the loss position. The net exposure on derivative agreements is presented in Note 12. Based on the netting provisions and collateral requirements associated with its derivative agreements and the creditworthiness of its derivative counterparties, Bank management does not currently anticipate any credit losses on its derivative agreements.

Note 14—Capital
At all times during the six months ended June 30, 2020,2021, the Bank was in compliance with all applicable statutory and regulatory capital requirements. The following table summarizes the Bank’s compliance with those capital requirements as of June 30, 20202021 and December 31, 20192020 (dollars in thousands):

Beginning in February 2020, the Bank must also maintain a minimum capital stock-to-assets ratio of 2.0 percent, as measured on a daily average basis at each month end. The Bank was in compliance with this requirement at each of the applicable month ends in 2021 and 2020.
Members are required to maintain an investment in Class B Capital Stock equal to the sum of a membership investment requirement and an activity-based investment requirement. The membership investment requirement is currently 0.04 percent of each member’s total assets as of December 31, 2019,2020, subject to a minimum of $1,000 and a maximum of $7,000,000. Through June 30, 2020,2021, the activity-based investment requirement was 4.1 percent of outstanding advances, except as described below.
On September 21, 2015, the Bank announced a Board-authorized reduction in the activity-based stock investment requirement from 4.1 percent to 2.0 percent for certain advances that were funded during the period from October 21, 2015 through December 31, 2015. To be eligible for the reduced activity-based investment requirement, advances funded during this period had to have a maturity of one year or greater, among other things. The standard activity-based stock investment requirement of 4.1 percent continued to apply to all other advances that were funded during the period from October 21, 2015 through December 31, 2015.
On February 28, 2020, the Bank announced another Board-authorized reduction in the activity-based stock investment requirement from 4.1 percent to 2.0 percent for up to $5.0 billion of advances that: (1) arewere funded during the period from April 1, 2020 through December 31, 2020 and (2) havehad a maturity of one year or greater. On July 1, 2020, the Bank announced a Board-authorized modification to this special advances offering. As modified, the Bank's activity-based capital stock investment requirement was reduced from 4.1 percent to 2.0 percent for advances that: (1) were funded during the period from August 1, 2020 through December 31, 2020 and (2) had a maturity of 28 days or greater. On December 7, 2020, the Bank announced that its Board of Directors had authorized the Bank to extend the expiration date of the special advances offering from December 31, 2020 to June 30, 2021. On March 17, 2021, the Bank announced another Board-authorized modification and extension to this special advances offering. As modified and extended, the Bank's activity-based capital stock investment requirement has been reduced from 4.1 percent to 2.0 percent for advances that: (1) are funded during the period from August 1, 2020April 19, 2021 through December 31, 20202021 and (2) have a maturity of 32 days or greater. For advances that were funded on or prior to April 18, 2021, the reduced activity-based capital stock investment requirement continued to apply to advances that had a maturity of 28 days or greater. Under the 2020 special advances offering described in this paragraph, the maximum balance of advances to which the reduced activity-based stock investment requirement can be applied is $5.0 billion. Except as described in this paragraph, the standard activity-based stock investment requirement of 4.1 percent continues to apply to all other advances that are funded during the period from April 1, 2020 through December 31, 2020.2021.
On April 19, 2021, the Bank implemented an amendment to its Capital Plan. The amended Capital Plan provides for the imposition of an activity-based investment requirement ranging from 0.10 percent to 2.0 percent of members' outstanding letters

of credit (the "LC Percentage"), as specified from time to time by the Bank's Board of Directors. The Board of Directors has established an LC Percentage of 0.10 percent which applies only to letters of credit that are issued or renewed on and after April 19, 2021. The LC Percentage is applied to the issued amount of the letter of credit rather than, if applicable, the amount of the letter of credit that is used from time to time during the term of the letter of credit. Further, renewals for this purpose include amendments that extend the expiration date of the letter of credit.
The Bank generally repurchases surplus stock quarterly. For the repurchases that occurred during the six months ended June 30, 2020,2021, surplus stock was defined as the amount of stock held by a member shareholder in excess of 125 percent of the shareholder’s minimum investment requirement. For those repurchases, which occurred on March 27, 202029, 2021 and June 26, 2020,25, 2021, a member shareholder's surplus stock was not repurchased if: (1) the amount of that shareholder's surplus stock was $2,500,000$2,000,000 or less, (2) the shareholder elected to opt-out of the repurchase, or (3) the shareholder was on restricted collateral status (subject to certain exceptions). On March 27, 202029, 2021 and June 26, 2020,25, 2021, the Bank repurchased surplus stock totaling $139,080,000$56,889,000 and $184,412,000,$35,836,000, respectively, none of which was classified as mandatorily redeemable capital stock at those dates.that date. From time to time, the Bank may modify the definition of surplus stock or the timing and/or frequency of surplus stock repurchases.

On March 27, 202029, 2021 and June 26, 2020,25, 2021, the Bank also repurchased all excess stock held by non-member shareholders as of those dates.that date. This excess stock, all of which was classified as mandatorily redeemable capital stock at those dates,that date, totaled $2,600$7,008,000 and $2,800,$1,000, respectively.
The Financing Corporation ("FICO") was formed pursuant to the Competitive Equality Banking Act of 1987 to provide financing for the resolution of failed savings and loan associations. The capitalization of FICO was provided by capital distributions from the FHLBanks in exchange for non-voting capital stock of FICO. The Bank's capital distributions were made in 1987, 1988 and 1989. Upon passage of the Financial Institutions Reform, Recovery and Enforcement Act of 1989, the Bank's capital stock investment in FICO was determined to be non-redeemable and, in 1989, the Bank charged off its investment in FICO directly against retained earnings. After satisfying its obligations in September 2019, FICO commenced a process to dissolve in accordance with relevant statutory requirements and the terms of a plan of dissolution approved by the Director of the Finance Agency. During the second quarter of 2020, in connection with the dissolution of FICO, the Bank received a distribution of $17,639,000, representing the Bank's proportionate share of FICO’s surplus and remaining cash on hand. The receipt of this distribution was treated as a partial return of the Bank's prior investment in FICO and credited to unrestricted retained earnings.

Note 16—Estimated Fair Values
Fair value is defined under U.S. GAAP as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. A fair value measurement assumes that the transaction to sell the asset or transfer the liability occurs in the principal market for the asset or liability or, in the absence of a principal market, the most advantageous market for the asset or liability. U.S. GAAP establishes a fair value hierarchy and requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. U.S. GAAP also requires an entity to disclose the level within the fair value hierarchy in which each measurement is classified. The fair value hierarchy prioritizes the inputs used to measure fair value into three broad levels:
33

Table of Contents
     Level 1 Inputs — Quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity can access at the measurement date.
     Level 2 Inputs — Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. If the asset or liability has a specified (contractual) term, a Level 2 input must be observable for substantially the full term of the asset or liability. Level 2 inputs include the following: (1) quoted prices for similar assets or liabilities in active markets; (2) quoted prices for identical or similar assets or liabilities in markets that are not active or in which little information is released publicly; (3) inputs other than quoted prices that are observable for the asset or liability (e.g., interest rates and yield curves that are observable at commonly quoted intervals and implied volatilities); and (4) inputs that are derived principally from or corroborated by observable market data (e.g., implied spreads).
     Level 3 Inputs — Unobservable inputs for the asset or liability that are supported by little or no market activity. None of the Bank’s assets or liabilities that are recorded at fair value on a recurring basis were measured using significant Level 3 inputs.
34

Table of Contents```
For financial instruments carried at fair value, the Bank reviews the fair value hierarchy classifications on a quarterly basis. Changes in the observability of the valuation inputs may result in a reclassification of certain assets or liabilities. For the six months ended June 30, 20202021 and 2019,2020, the Bank did not reclassify any fair value measurements.
The following estimated fair value amounts have been determined by the Bank using available market information and management’s best judgment of appropriate valuation methods. These estimates are based on pertinent information available to the Bank as of June 30, 20202021 and December 31, 2019.2020. Although management uses its best judgment in estimating the fair value of these financial instruments, there are inherent limitations in any estimation technique or valuation methodology. For example, because an active secondary market does not exist for many of the Bank’s financial instruments (e.g., advances, non-agency RMBS and mortgage loans held for portfolio), in certain cases their fair values are not subject to precise quantification or verification. Therefore, the estimated fair values presented below in the Fair Value Summary Tables may not be indicative of the amounts that would have been realized in market transactions at the reporting dates. Further, the fair values do not represent an estimate of the overall market value of the Bank as a going concern, which would take into account future business opportunities.
The valuation techniques used to measure the fair values of the Bank’s financial instruments that are measured at fair value on the statement of condition are described below.
       Trading and available-for-sale securities. To value its U.S. Treasury Notes and U.S. Treasury Bills classified as trading securities and all of its available-for-sale securities, the Bank obtains prices from three designated third-party pricing vendors when available.
The pricing vendors use various proprietary models to price these securities. 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. Because many securities do not trade on a daily basis, the pricing vendors use available information as applicable such as benchmark curves, benchmarking of like securities, sector groupings and matrix pricing to determine the prices for individual securities. Each pricing vendor has an established challenge process in place for all security valuations, which facilitates resolution of potentially erroneous prices identified by the Bank.
A "median" price is first established for each security using a formula that is based upon the number of prices received. If three prices are received, the middle price is the median price; if two prices are received, the average of the two prices is the median price; and if one price is received, it is the median price (and also the final price) subject to some type of validation similar to the evaluation of outliers described below. All prices that are within a specified tolerance threshold of the median price are included in the “cluster” of prices that are averaged to compute a “default” price. All prices that are outside the threshold (“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 an outlier (or some other price identified in the analysis) is determined to be a better estimate of fair value, then the outlier (or the other price, as appropriate) is used as the final price rather than the default price. If, on the other hand, the analysis confirms that an outlier (or outliers) is (are) in fact not representative of fair value and the default price is the best estimate, then the default price is used as the final price. In all cases, the final price is used to determine the fair value of the security.
If all prices received for a security are outside the tolerance threshold level of the median price, then there is no default price, and the final price is determined by an evaluation of all outlier prices as described above.
As of June 30, 20202021 and December 31, 2019,2020, three vendor prices were received for substantially all of the Bank’s trading and available-for-sale securities and the final prices for substantially all of those securities were computed by averaging the three prices. Based on the Bank's understanding of the pricing methods employed by the third-party pricing vendors and the relative lack of dispersion among the vendor prices (or, in those instances in which there were outliers, the Bank's additional
34

Table of Contents
analyses), the Bank believes its final prices result in reasonable estimates of the fair values and that the fair value measurements are classified appropriately in the fair value hierarchy.
       Derivative assets/liabilities. The fair values of the Bank’s interest rate swap and swaption agreements are estimated using a pricing model with inputs that are observable in the market (e.g., the relevant interest rate curves (that is, the relevant LIBOR swap curve, the SOFR curve or the OIS curve and, for purposes of discounting, either the OIS curve)curve for bilateral contracts or the SOFR curve for cleared contracts) and, for agreements containing options, swaption volatility). The fair values of the Bank’s interest rate caps and floors are also estimated using a pricing model with inputs that are observable in the market (that is, cap/floorcap volatility, the relevant LIBOR swap curve and, for purposes of discounting, the OIS curve).
As the collateral (or variation margin in the case of daily settled contracts) and netting provisions of the Bank’s arrangements with its derivative counterparties significantly reduce the risk from nonperformance (see Note 12), the Bank does not consider its own nonperformance risk or the nonperformance risk associated with each of its counterparties to be a significant factor in the valuation of its derivative assets and liabilities. The Bank compares the fair values obtained from its
35

Table of Contents```
pricing model to clearinghouse valuations (in the case of cleared derivatives) and non-binding dealer estimates (in the case of bilateral derivatives) and may also compare its fair values to those of similar instruments to ensure that the fair values are reasonable.
The fair values of the Bank’s derivative assets and liabilities include accrued interest receivable/payable and cash collateral remitted to/received from counterparties; the estimated fair values of the accrued interest receivable/payable and cash collateral approximate their carrying values due to their short-term nature. The fair values of the Bank's bilateral derivatives are netted by counterparty pursuant to the provisions of the credit support annexes to the Bank’s master netting agreements with its non-member bilateral derivative counterparties. The Bank's cleared derivative transactions with each clearing member of each clearinghouse are netted pursuant to the Bank's arrangements with those parties. In each case, if the netted amounts are positive, they are classified as an asset and, if negative, as a liability.
The Bank estimates the fair values of mortgage delivery commitments based upon the prices for to-be-announced ("TBA") securities, which represent quoted market prices for forward-settling agency MBS. The prices are adjusted for differences in coupon, cost to carry, vintage, remittance type and product type between the Bank's mortgage loan commitments and the referenced TBA MBS.
Other assets held at fair value. To value its mutual fund investments included in other assets, the Bank obtains quoted prices for the mutual funds.

Note 17—Commitments and Contingencies

Joint and several liability. The Bank is jointly and severally liable with the other 10 FHLBanks for the payment of principal and interest on all of the consolidated obligations issued by the FHLBanks. At June 30, 2020,2021, the par amount of the other 10 FHLBanks’ outstanding consolidated obligations was approximately $847$614 billion. The Finance Agency, in its discretion, may require any FHLBank to make principal or interest payments due on any consolidated obligation, regardless of whether there has been a default by a FHLBank having primary liability. To the extent that a FHLBank makes any consolidated obligation payment on behalf of another FHLBank, the paying FHLBank is entitled to reimbursement from the FHLBank with primary liability. However, if the Finance Agency determines that the primary obligor is unable to satisfy its obligations, then the Finance Agency may allocate the outstanding liability among the remaining FHLBanks on a pro rata basis in proportion to each FHLBank’s participation in all consolidated obligations outstanding, or on any other basis that the Finance Agency may

determine. No FHLBank has ever failed to make any payment on a consolidated obligation for which it was the primary obligor; as a result, the regulatory provisions for directing other FHLBanks to make payments on behalf of another FHLBank or
37

Table of Contents
allocating the liability among other FHLBanks have never been invoked. If the Bank expected that it would be required to pay any amounts on behalf of its co-obligors under its joint and several liability, the Bank would charge to income the amount of the expected payment. Based upon the creditworthiness of the other FHLBanks, the Bank currently believes that the likelihood that it would have to pay any amounts beyond those for which it is primarily liable is remote.
Other commitments and contingencies. At June 30, 20202021 and December 31, 2019,2020, the Bank had commitments to make additional advances totaling approximately $23,775,000$3,612,000 and $19,397,000,$7,161,000, respectively. In addition, outstanding standby letters of credit totaled $22,077,455,000$21,395,723,000 and $21,781,829,000$22,402,688,000 at June 30, 20202021 and December 31, 2019,2020, respectively. Based on management’s credit analyses and collateral requirements, the Bank does not deem it necessary to have any provision for credit losses on these letters of credit (see Note 9).
The Bank has entered into standby bond purchase agreements with a state housing finance agency within its district whereby, for a fee, the Bank agrees to serve as a standby liquidity provider. If required, the Bank will purchase and hold the housing finance agency's bonds until the designated marketing agent can find a suitable investor or the housing finance agency repurchases the bonds according to a schedule established by the agreement. Each standby bond purchase agreement includes the provisions under which the Bank would be required to purchase the bonds. At June 30, 20202021 and December 31, 2019,2020, the Bank had outstanding standby bond purchase agreements totaling $724,733,000$939,902,000 and $484,872,000,$709,300,000, respectively. At June 30, 2020,2021, standby bond purchase agreements totaling $180,615,000, $239,475,000, $51,302,000,$170,322,000, $221,223,000, $48,306,000, $246,558,000, and $253,341,000$253,493,000 expire in 2022, 2023, 2024, 2025 and 2025,2026, respectively. The Bank was not required to purchase any bonds under these agreements during the six months ended June 30, 20202021 or the year ended December 31, 2019.2020.
At June 30, 20202021 and December 31, 2019,2020, the Bank had commitments to purchase conventional mortgage loans totaling $44,951,000$45,342,000 and $31,765,000,$21,569,000, respectively, from certain of its members that participate in the MPF program.
At June 30, 2020,2021, the Bank had commitments to issue $50,000,000 (par value) of consolidated obligation bonds, none of which were hedged. At December 31, 2019, the Bank had commitments to issue $115,000,000$490,000,000 (par value) of consolidated obligation bonds, all of which were hedged with interest rate swaps. The Bank did not have any commitments to issue consolidated obligation bonds at December 31, 2020. In addition, at June 30, 20202021 and December 31, 2019,2020, the Bank had commitments to issue $61,422,000$40,288,000 and $679,510,000$521,760,000 (par value), respectively, of consolidated obligation discount notes, none of which were hedged.
The Bank has transacted interest rate exchange agreements with large financial institutions and third-party clearinghouses that are subject to collateral exchange arrangements. As of June 30, 20202021 and December 31, 2019,2020, the Bank had pledged cash collateral of $696,453,000$373,135,000 and $156,676,000,$466,068,000, respectively, to those parties that had credit risk exposure to the Bank related to interest rate exchange agreements. The pledged cash collateral (i.e., interest-bearing deposit asset) is netted against derivative assets and liabilities in the statements of condition. In addition, as of June 30, 20202021 and December 31, 2019,2020, the Bank had pledged securities with carrying values (and fair values) of $866,039,000$612,245,000 and $842,256,000,$737,500,000, respectively, to parties that had credit risk exposure to the Bank related to interest rate exchange agreements. The pledged securities may be rehypothecated and are not netted against derivative assets and liabilities in the statements of condition.
In the ordinary course of its business, the Bank is subject to the risk that litigation may arise. Currently, the Bank is not a party to any material pending legal proceedings.

Note 18— Transactions with Shareholders
AffiliatesAn affiliate of twoone of the Bank’s derivative counterparties (Citigroup and Wells(Wells Fargo) acquired a member institutionsinstitution on March 31, 2005 and October 1, 2006, respectively.2006. Since the acquisitions wereacquisition was completed, the Bank has continued to enter into interest rate exchange agreements with Citigroup and Wells Fargo in the normal course of business and under the same terms and conditions as before. In addition, the Bank maintains interest-bearing deposits with affiliates of Citigroup and Wells Fargo. Effective October 1, 2006, Citigroup terminated the Ninth District charter of the affiliate that acquired the member institution and, as a result, an affiliate of Citigroup became a non-member shareholder of the Bank. The Bank repurchased all of the affiliate's outstanding capital stock during the three months ended June 30, 2019 and, accordingly, the affiliate of Citigroup is no longer a shareholder of the Bank.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
The following discussion and analysis of financial condition and results of operations should be read in conjunction with the financial statements and notes thereto included in “Item 1. Financial Statements.”
Forward-Looking Information
This quarterly report contains forward-looking statements that reflect current beliefs and expectations of the Federal Home Loan Bank of Dallas (the “Bank”) about its future results, performance, liquidity, financial condition, prospects and opportunities. These statements are identified by the use of forward-looking terminology, such as “anticipates,” “plans,” “believes,” “could,” “estimates,” “may,” “should,” “would,” “will,” “might,” “expects,” “intends” or their negatives or other similar terms. The Bank cautions that forward-looking statements involve risks or uncertainties that could cause the Bank’s actual results to differ materially from those expressed or implied in these forward-looking statements, or could affect the extent to which a particular objective, projection, estimate or prediction is realized. As a result, undue reliance should not be placed on these statements.
These risks and uncertainties include, without limitation, evolving economic and market conditions, political events, and the impact of competitive business forces. The risks and uncertainties related to evolving economic and market conditions include, but are not limited to, changes in interest rates, changes in the Bank’s access to the capital markets, changes in the cost of the Bank’s debt, changes in the ratings on the Bank’s debt, adverse consequences resulting from a significant regional, national or global economic downturn (including, but not limited to, reduced demand for the Bank's products and services), credit and prepayment risks, changes in the financial health of the Bank’s members or non-member borrowers and the ongoing effects from the COVID-19 pandemic, and the decline in oil prices since the beginning of 2020.pandemic. Among other things, political events could possibly lead to changes in the Bank’s regulatory environment or its status as a government-sponsored enterprise (“GSE”), or to changes in the regulatory environment for the Bank’s members or non-member borrowers. Risks and uncertainties related to competitive business forces include, but are not limited to, the potential loss of a significant amount of member borrowings through acquisitions or other means (including, but not limited to, the availability of other sources of liquidity resulting from various U.S. government programs that have been established in response to the COVID-19 crisis) or changes in the relative competitiveness of the Bank’s products and services for member institutions. For a more detailed discussion of the risk factors applicable to the Bank, see “Item 1A — Risk Factors” in the Bank’s Annual Report on Form 10-K for the year ended December 31, 2019,2020, which was filed with the Securities and Exchange Commission (“SEC”) on March 25, 202024, 2021 (the “2019“2020 10-K”). The Bank undertakes no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events, changed circumstances, or any other reason.
Overview
Business
The Bank is one of 11 district Federal Home Loan Banks (each individually a “FHLBank” and collectively the “FHLBanks” and, together with the Federal Home Loan Banks Office of Finance ("Office of Finance"), a joint office of the FHLBanks, the “FHLBank System”) that were created by the Federal Home Loan Bank Act of 1932. The FHLBanks serve the public by enhancing the availability of credit for residential mortgages, community lending and targeted community development. As independent, member-owned cooperatives, the FHLBanks seek to maintain a balance between their public purpose and their ability to provide adequate returns on the capital supplied by their members. The Federal Housing Finance Agency (“Finance Agency”), an independent agency in the executive branch of the U.S. government, is responsible for supervising and regulating the FHLBanks and the Office of Finance. The Finance Agency’s stated mission is to ensure that the housing GSEs, including the FHLBanks, 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. Consistent with this mission, the Finance Agency establishes policies and regulations covering the operations of the FHLBanks.
The Bank serves eligible financial institutions in Arkansas, Louisiana, Mississippi, New Mexico and Texas (collectively, the Ninth District of the FHLBank System). The Bank’s primary business is lending relatively low cost funds (known as advances) to its member institutions, which include commercial banks, savings institutions, insurance companies, credit unions, and Community Development Financial Institutions that are certified under the Community Development Banking and Financial Institutions Act of 1994. While not members of the Bank, housing associates, including state and local housing authorities, that meet certain statutory criteria may also borrow from the Bank. The Bank also maintains a portfolio of investments, substantially all of which are highly rated, for liquidity purposes and to provide additional earnings. Additionally, the Bank holds interests in a portfolio of predominately conventional mortgage loans that were acquired through the Mortgage Partnership Finance® (“MPF”®) Program administered by the FHLBank of Chicago. Shareholders’ return on their investment includes dividends (which are typically paid quarterly in the form of capital stock) and the value derived from access to the Bank’s products and services. Historically, the Bank has balanced the financial rewards to shareholders by seeking to pay a dividend that meets or

exceeds the return on alternative short-term money market investments available to shareholders, while lending funds at the lowest rates expected to be compatible with that objective and its objective to build retained earnings over time.
The Bank’s capital stock is not publicly traded and can be held only by members of the Bank, by non-member institutions that acquire stock by virtue of acquiring member institutions, by a federal or state agency or insurer acting as a receiver of a closed institution, or by former members of the Bank that retain capital stock to support advances or other obligations that remain outstanding or until any applicable stock redemption or withdrawal notice period expires. All members must hold stock in the Bank. The Bank’s capital stock has a par value of $100 per share and is purchased, redeemed, repurchased and transferred only at its par value. By regulation, the parties to a transaction involving the Bank's stock can include only the Bank and its member institutions (or non-member institutions or former members, as described above). While a member could transfer stock to another member of the Bank, that transfer could occur only upon approval of the Bank and then only at par value. Members may redeem excess stock, or withdraw from membership and redeem all outstanding capital stock, with five years’ written notice to the Bank.
The FHLBanks’ debt instruments (known as consolidated obligations) are their primary source of funds and are the joint and several obligations of all 11 FHLBanks. Consolidated obligations are issued through the Office of Finance (acting as agent for the FHLBanks) and generally are publicly traded in the over-the-counter market. The Bank records on its statements of condition only those consolidated obligations for which it receives the proceeds. Consolidated obligations are not obligations of the U.S. government and the U.S. government does not guarantee them. Consolidated obligations are currently rated Aaa/P-1 by Moody’s Investors Service (“Moody’s”) and AA+/A-1+ by S&P Global Ratings (“S&P”). These ratings indicate that each of these nationally recognized statistical rating organizations ("NRSROs") has concluded that the FHLBanks have a very strong capacity to meet their commitments to pay principal and interest on consolidated obligations. The ratings also reflect the FHLBank System’s status as a GSE. Historically, the FHLBanks’ GSE status and very high credit ratings on consolidated obligations have provided the FHLBanks with excellent capital markets access. Deposits, other borrowings and the proceeds from capital stock issued to members are also sources of funds for the Bank.
In addition to ratings on the FHLBanks’ consolidated obligations, each FHLBank is rated individually by both S&P and Moody’s. These individual FHLBank ratings apply to the individual obligations of the respective FHLBanks, such as interest rate derivatives, deposits and letters of credit. As of June 30, 2020,2021, Moody’s had assigned a deposit rating of Aaa/P-1 to each of the FHLBanks and S&P had rated each of the FHLBanks AA+/A-1+.
Shareholders, bondholders and prospective shareholders and bondholders should understand that these credit ratings are not a recommendation to buy, hold or sell securities and they may be subject to revision or withdrawal at any time by the NRSRO. The ratings from each of the NRSROs should be evaluated independently.
The Bank conducts its business and fulfills its public purpose primarily by acting as a financial intermediary between its members and the capital markets. The intermediation of the timing, structure and amount of its members’ credit needs with the investment requirements of the Bank’s creditors is made possible by the extensive use of interest rate exchange agreements, including interest rate swaps, swaptions and caps.
The Bank’s profitability objective is to generate sufficient earnings to allow the Bank to continue to increase its retained earnings and pay dividends on capital stock at rates that meet the Bank's dividend targets. All other things being equal, the Bank’s earnings are typically expected to rise and fall with the general level of market interest rates, particularly short-term money market rates, and the Bank's total capital and asset size. Other factors that could have an effect on the Bank’s future earnings include the level, volatility of and relationships between short-term money market rates such as federal funds, the Secured Overnight Financing Rate ("SOFR") and one-month and three-month LIBOR; the availability and cost of the Bank’s short- and long-term debt relative to benchmark rates such as federal funds, SOFR, one- and three-month LIBOR, and long-term fixed mortgage rates; the availability of interest rate exchange agreements at competitive prices; whether the Bank’s larger borrowers continue to be members of the Bank and the level at which they maintain their borrowing activity; the extent to which the Bank's members continue to sell mortgage loans to the Bank; and the impact of economic and financial market conditions on both the near-term and longer-term demand for the Bank’s credit products.
Currently, the Bank's target for quarterly dividends on Class B-1 Stock is an annualized rate that approximates the average one-month LIBOR rate for the immediately preceding quarter. The target range for quarterly dividends on Class B-2 Stock is currently an annualized rate that approximates the average one-month LIBOR rate for the preceding quarter plus 0.5 - 1.0 percent. While the Bank has had a long-standing practice of paying quarterly dividends, future dividend payments cannot be assured.
The Bank operates in only one reportable segment. All of the Bank’s revenues are derived from U.S. operations.

Financial Market Conditions
During the first half of 2020,2021, economic growth in the United States was negatively impacted bycontinued to recover from the negative impact of the novel coronavirus known as COVID-19, which was declared a global pandemic by the World Health Organization on March 11, 2020. To date,During 2020, COVID-19 has caused significant economic and financial turmoil both in the U.S. and around the world,world. Although vaccinations are progressing, the pace of vaccination has slowed and the emergence of variants has fueled concerns that it could leadcaused the number of cases to a prolonged global recession. At this time, itonce again increase in many parts of the United States. It is not possible at this time to estimate how long it will take to halt the spread of the virus or the longer-term effects that COVID-19 could have on the Bank's business.virus. Many businesses in the Bank's district and across the U.S. were forced to shut down operations during 2020 in an attempt to slow the spread of the virus. Despite signs that the virus is continuing to spread, beginning in late April/early May someMany of these previously closed businesses have been allowednow reopened while others have increased capacity, in many cases with some restrictions. The extent to reopen in some locationswhich the COVID-19 pandemic affects the Bank's business will depend on many factors that remain uncertain and difficult to predict including, but generally at reduced capacitynot limited to, the duration, spread and with restrictions that are designedseverity of the pandemic; fiscal or monetary stimulus; the actions taken to keep people safe.contain the pandemic; and how quickly and to what extent normal economic and operating conditions can resume.
The gross domestic product decreasedincreased at an annual rate of 32.96.5 percent during the second quarter of 2020,2021, after increasing at an annual rate of 6.3 percent during the first quarter of 2021 and decreasing at an annual rate of 5.03.4 percent during 2020. The increases in the gross domestic product during the first quarterhalf of 2020.2021 reflected continued efforts to reopen businesses and resume activities that had been postponed or restricted due to COVID-19. The nationwide unemployment rate increaseddecreased from 3.56.7 percent at December 31, 20192020 to 4.46.0 percent at March 31, 2020. Unemployment claims increased dramatically during the second quarter of 2020 as employers laid off workers in response to the significant reduction in economic activity. By the end of April 2020, the unemployment rate surged to 14.7 percent before declining to 11.12021 and 5.9 percent at June 30, 2020.2021, reflecting the improvement in economic activity since the beginning of the pandemic.
At itsIn an unscheduled meeting held on January 28/29,March 15, 2020, the Federal Open Market Committee ("FOMC") maintainedlowered its target for the federal funds rate at a range between 1.50 percent and 1.75 percent (which it had set in October 2019). In an unscheduled meeting held on March 3, 2020, the FOMC stated that the COVID-19 outbreak posed evolving risks to economic activity and, in support of achieving its maximum employment and price stability goals, it decided to lower the target range for the federal funds rate by 50100 basis points to a range between 1.00 percent and 1.25 percent, noting that it would closely monitor developments and their implications for the economic outlook and would act as appropriate to support the economy. On March 15, 2020, the FOMC again lowered the federal funds rate in another unscheduled meeting, this time to a target range between 0 percent and 0.25 percent, noting that the COVID-19 outbreak had harmed communities and disrupted economic activity in many countries, including the United States, and had significantly affected global financial conditions. AtEarlier in that same month in another unscheduled meeting, the FOMC had lowered its scheduled meeting on July 28/29, 2020,target for the federal funds rate by 50 basis points, to a range between 1.00 percent and 1.25 percent. The FOMC maintained the target for the federal funds rate at a range between 0 percent and 0.25 percent throughout the remainder of 2020 and the first half of 2021. At its scheduled meeting on July 27/28, 2021, the FOMC maintained the target for the federal funds rate at that range and stated that it expects to maintain this target range until it is confident thatlabor market conditions have reached levels consistent with the economyFOMC’s assessments of maximum employment and inflation has weathered recent eventsrisen to 2 percent and is on track to achievemoderately exceed 2 percent for some time. With inflation having run persistently below its maximum employment and price stability goals.
Thelonger-run goal of 2 percent, the FOMC further stated that it will continueaim to purchaseachieve inflation moderately above 2 percent for some time so that inflation averages 2 percent over time and longer-term inflation expectations remain well anchored at 2 percent.

Due to the dramatic increase in volatility across the global capital markets that occurred at the onset of the COVID-19 pandemic, the Federal Reserve has also undertakenundertook a number of other emergency actions. Notably, the Federal Reserve increased substantially its provision of liquidity to the repo and U.S. Treasury markets via open market operations while also providing liquidity to related markets, such as the commercial paper market, via an array of new programs.programs, many of which expired on March 31, 2021. On July 28, 2021, the FOMC announced the establishment of two standing repurchase agreement facilities (a domestic facility and a repo facility for foreign and international monetary authorities), which are intended to support the effective implementation of monetary policy and smooth market functioning.

The Secured Overnight Financing Rate ("SOFR") declined by 145 basis pointsdecline in interest rates abated somewhat during the first six monthssecond half of 2020, from 1.55 percent to 0.10 percent.

(3)Mandatorily redeemable capital stock represents capital stock that is classified as a liability under accounting principles generally accepted in the United States of America. Dividends on mandatorily redeemable capital stock are recorded as interest expense and excluded from dividends paid. Dividends paid on mandatorily redeemable capital stock totaled $30$8 thousand, $39$10 thousand, $46$31 thousand, $54$10 thousand and $51$30 thousand for the quarters ended June 30, 2020,2021, March 31, 2020,2021, December 31, 2019,2020, September 30, 20192020 and June 30, 2019,2020, respectively.
(4)In accordance with ASU 2017-12, "Targeted Improvements to Accounting for Hedging Activities" ("ASU 2017-12"Under accounting principles generally accepted in the United States of America (“U.S. GAAP”), changes in the fair value of a derivative in a qualifying fair value hedge along with changes in the fair value of the hedged asset or liability attributable to the hedged risk (the net amount of which is referred to as fair value hedge ineffectiveness) are recorded in net interest income. Fair value hedge ineffectiveness increased (reduced) net interest income by $9.4($5.8 million), $19.5 million, $(36.9)$7.9 million, $13.3 million, $(6.3)$4.6 million and $(15.6)$9.4 million for the quarters ended June 30, 2020,2021, March 31, 2020,2021, December 31, 2019,2020, September 30, 20192020 and June 30, 2019,2020, respectively.

(5)Net interest margin is net interest income as a percentage of average earning assets.
(6)Net interest spread is the difference between the yield on interest-earning assets and the cost of interest-bearing liabilities.
(7)Return on average capital stock is derived by dividing net income by average capital stock balances excluding mandatorily redeemable capital stock.
(8)The regulatory capital ratio is computed by dividing regulatory capital (the sum of capital stock — putable, mandatorily redeemable capital stock and retained earnings) by total assets at each quarter-end.

Legislative and Regulatory Developments
Coronavirus Aid, Relief,LIBOR Transition – 2021 ISDA Interest Rate Derivatives Definitions
On June 11, 2021, the International Swaps and Economic SecurityDerivatives Association (“CARES”ISDA”) Act
published the 2021 ISDA Interest Rate Derivatives Definitions ("2021 ISDA Definitions"), which will update and consolidate the frequently supplemented 2006 ISDA Definitions as the standard definitions for cleared and uncleared interest rate derivatives. The CARES Act was signed into law by2021 ISDA Definitions incorporate prior supplements to the President2006 ISDA Definitions in addition to other changes which were made to conform to updates in market practice and regulation. Both the 2006 ISDA Definitions (as supplemented effective January 25, 2021) and the 2021 ISDA Definitions contain ISDA-recommended fallbacks for interest rate derivatives referencing an Interbank Offered Rate, including U.S. Dollar LIBOR. ISDA has announced that implementation of the United States2021 ISDA Definitions is expected to occur for clearing houses, trading venues and other market infrastructures between October 1, 2021 and October 4, 2021. While market participants may continue to use the current 2006 ISDA Definitions, ISDA will not incorporate any further supplements following implementation of the 2021 ISDA Definitions.
The future implementation of the 2021 ISDA Definitions is not expected to have a material impact on March 27, 2020. The $2.2 trillion package is the largest stimulus bill in U.S. historyBank’s financial condition or results of operations.
Affordable Housing and Community Investment
Legislation was undertaken in response to the COVID-19 crisis impacting the country. The CARES Act followed previous relief legislation that was enacted earlierrecently introduced in the same month. The CARES Act:
Provided assistance to businesses, states,U.S. Senate and municipalities.
Created a loan program for small businesses, non-profits and physician practices that can be forgiven through employee retention incentives (known as the Paycheck Protection Program or “PPP”).
Authorized the U.S. Treasury Secretary to make loans or loan guarantees to states, municipalities, and eligible businesses and loosens some regulations imposed by the Dodd-Frank Wall Street Reform and Consumer Protection Act (the "Dodd-Frank Act").
Provided one-time direct payments to eligible taxpayers and their families.
Expanded eligibility for unemployment insurance and increased benefit amounts through July 31, 2020.
Included mortgage forbearance provisions and a foreclosure moratorium (the foreclosure moratorium on federally backed properties was extended on June 17, 2020 to last until at least August 31, 2020).
Funding for the PPP was increased on April 24, 2020 with the enactmentHouse of the Paycheck Protection Program and Healthcare Enhancement Act and, on July 1, 2020, the PPP was extended to August 8, 2020. Additional phases of the CARES Act or other COVID-19 relief legislation may beRepresentatives which, if enacted in its proposed form, would require the future.FHLBanks to set aside a higher percentage of their earnings for their affordable housing and community investment programs than is currently required under law. The Bank is continuing to evaluate the potential impact of the CARES Act on its business and it isactively monitoring the impact that this legislation could have on its mortgage loans held for portfolio as well as the mortgages held by the Bank’s members and that the Bank accepts as collateral.proposal.

Finance Agency Supervisory Letter Regarding PPP Loans as Collateral for Advances
On April 23, 2020, the Finance Agency issued a Supervisory Letter (the “PPP Supervisory Letter”) permitting the FHLBanks to accept loans made through the PPP as collateral for advances given the Small Business Administration’s 100 percent guarantee of the unpaid principal balance of the loans. On April 20, 2020, the Small Business Administration published its third interim final rule related to PPP loans which, among other things, explicitly waived certain regulatory requirements that must be satisfied before a member could pledge PPP loans to the FHLBanks as collateral. The PPP Supervisory Letter establishes a series of conditions under which the FHLBanks may accept PPP loans as collateral. These conditions focus on the financial condition of members, collateral discounts that must be applied to PPP loans, caps on the percentage of a member’s lendable pledged collateral that PPP loans can constitute, and pledge dollar limits.
On April 27, 2020, the Bank began accepting PPP loans as eligible collateral. The Bank does not expect its acceptance of PPP loans as collateral to materially affect its financial condition or results of operations.
Additional COVID-19 Developments
In response to the COVID-19 pandemic, the President of the United States (through executive orders), governmental agencies (including the SEC, Office of the Comptroller of the Currency ("OCC"), Federal Reserve Board ("FRB"), FDIC, National Credit Union Administration, Commodity Futures Trading Commission ("CFTC") and the Finance Agency), as well as state governments and agencies, have taken, and may continue to take, actions to provide various forms of relief from, and guidance regarding, the financial, operational, credit, market and other effects arising from the pandemic, some of which may have a direct or indirect impact on the Bank and/or its members. Many of these actions are temporary in nature. The Bank continues to monitor these actions and guidance as they evolve and to evaluate their potential impact on the Bank.
Margin and Capital Requirements for Covered Swap Entities
On July 1, 2020, the OCC, FRB, FDIC, Farm Credit Administration, and the Finance Agency (collectively, the “Prudential Banking Regulators”) jointly published a final rule, which becomes effective on August 31, 2020, that amends regulations establishing minimum margin and capital requirements for non-cleared derivatives for covered swap entities under the jurisdiction of the Prudential Banking Regulators (the “Prudential Margin Rules”). In addition to other changes, the final rule: (1) allows non-cleared derivatives entered into by a covered swap entity prior to an applicable compliance date to retain their legacy status and not become subject to the Prudential Margin Rules in the event that such legacy derivatives are amended to replace an interbank offered rate (such as LIBOR) or another discontinued rate, or are otherwise modified due to other technical amendments such as reductions of notional amounts or portfolio compression exercises; (2) introduces a new Phase 6 compliance date for initial margin requirements for covered swap entities and their counterparties with an average daily aggregate notional amount of non-cleared derivatives between $8 billion and $50 billion, and limits Phase 5 compliance to covered swap entities and their counterparties with an average daily aggregate notional amount of non-cleared derivatives between $50 billion and $750 billion; and (3) clarifies that initial margin trading documentation does not need to be executed prior to a counterparty reaching the initial margin threshold.
On the same date, the Prudential Banking Regulators issued an interim final rule, effective September 1, 2020, extending the initial margin compliance date for Phase 5 counterparties to September 1, 2021 and extending the initial margin compliance date for Phase 6 counterparties to September 1, 2022. On July 10, 2020, the CFTC issued a final rule and a proposed rule which collectively, among other things, extend the initial margin compliance dates for Phase 5 and Phase 6 counterparties to September 1, 2021 and September 1, 2022, thereby aligning its rules with those of the Prudential Banking Regulators.
While the Bank is not a covered swap entity under the Prudential Margin Rules, it transacts its non-cleared derivatives with covered swap entities and it is likely that it will have an aggregate notional amount of non-cleared derivatives between $8 billion and $50 billion when the initial margin requirements become effective on September 1, 2022 (at June 30, 2020, the aggregate notional balance of the Bank's non-cleared derivatives was $14.9 billion). If the Bank's aggregate notional balance of its non-cleared derivatives is between $8 billion and $50 billion on September 1, 2022, its obligation to post initial margin would occur when its unmargined exposure (excluding legacy derivatives) exceeds $50 million on a counterparty-by-counterparty basis. If the Bank is ultimately required to post initial margin, it anticipates that its costs of engaging in non-cleared derivatives may increase.
Finance Agency Final Rule on FHLBank Housing Goals Amendments
On June 3, 2020, the Finance Agency issued a final rule which amends the FHLBank housing goals regulation. Enforcement of the final rule, which becomes effective on August 24, 2020, will phase in over three years. The final rule replaces the four existing retrospective housing goals with a single prospective mortgage purchase housing goal target in which 20 percent of any mortgage loans that are purchased in a calendar year must be comprised of loans to low-income or very low-income families, or to families in low-income areas. The final rule also establishes a separate small member participation housing goal. Under this provision of the final rule, a target level of 50 percent of a FHLBank’s members that are selling mortgage loans to the FHLBank in a calendar year must be small members. The final rule provides that a FHLBank may request Finance Agency

approval of alternative target levels for either or both of the goals. The final rule also establishes that housing goals apply to each FHLBank that acquires any mortgage loans during a calendar year, eliminating the existing $2.5 billion volume threshold that previously triggered the application of housing goals for each FHLBank.
The Bank is still evaluating the impact that this rule could have on its future purchase volumes.

Financial Condition
The following table provides selected period-end balances as of June 30, 20202021 and December 31, 2019,2020, as well as selected average balances for the six-month period ended June 30, 20202021 and the year ended December 31, 2019.2020. As shown in the table, the Bank’s total assets decreased by 0.69.7 percent between December 31, 20192020 and June 30, 2020,2021, due primarily to a decreasedecreases in the Bank's advances ($7.6 billion), long-term investments ($0.6 billion) and mortgage loans held for portfolio ($0.2 billion), partially offset by an increase in the Bank's short-term liquidity portfolio ($2.6 billion) offset by increases in the Bank's advances ($1.5 billion) and the carrying value of the its long-term investments ($0.72.1 billion). As the Bank's assets decreased, the funding for those assets also decreased.

Advances
The Bank's advances balances (at par value) increaseddecreased by $0.9$7.4 billion (2(23 percent) during the first six months of 2020. After declining2021. Advances to commercial banks decreased $5.7 billion, contributing significantly to the overall decline in advances during the first two months of 2020, demand forperiod. Texas Capital Bank, N.A. (the Bank's second largest borrower at December 31, 2020), Comerica Bank (the Bank's third largest borrower at December 31, 2020) and Origin Bank (the Bank's ninth largest borrower at December 31, 2020) reduced their advances increased markedly in Marchby $1.0 billion, $2.8 billion and the first half of April 2020 in response to the COVID-19 outbreak. The Bank believes the unsettled nature of the credit markets at that time led some members to increase their borrowings in order to increase their liquidity. As part of a broader COVID-19 Relief Program, the Bank made available $5.0$0.7 billion, of below-market rate advances in mid-April. The vast majority of these fixed-rate advances had a term of six months and all were prepayable without a prepayment fee. During the latter part of April, the Bank's advances began to decline and continued to do sorespectively, during the remainder of the second quarter.period. Advances outstanding to these institutions totaled $3.0 billion, $2.8 billion and $0.9 billion, respectively, at December 31, 2020. During this time, the level of liquidity in the financial markets was significantly elevated due in large part to the various initiatives that were undertaken by the Federal Reserve in response to the pandemic, which in turn dampened demand for the Bank's advances. At June 30, 2020, only $1.9 billion of the below-market rate advances remained outstanding.
While it is difficult to predict the future level of advances, it is possible that the Bank's advances could continue to fall if the level of liquidity in the financial markets remains elevated. BeyondAdditional U.S. government stimulus, if any, could further increase the already elevated level of liquidity the future level of advanceswhich could, also be negatively impacted depending upon the duration and severity ofin turn, diminish even further the current economic downturn resulting fromsubdued demand for the COVID-19 pandemic.Bank's advances.

The Bank is required by statute and regulation to obtain sufficient collateral from members/borrowers to fully secure all advances and other extensions of credit. The Bank’s collateral arrangements with its members/borrowers and the types of collateral it accepts to secure advances are described in the 20192020 10-K. To ensure the value of collateral pledged to the Bank is sufficient to secure its advances, the Bank applies various haircuts, or discounts, to determine the value of the collateral against which borrowers may borrow. From time to time, the Bank reevaluates the adequacy of its collateral haircuts under a range of stress scenarios to ensure that its collateral haircuts are sufficient to protect the Bank from credit losses on advances.
In addition, as described in the 20192020 10-K, the Bank reviews the financial condition of its depository institution borrowers on at least a quarterly basis to identify any borrowers whose financial condition indicates they might pose an increased credit risk and, as needed, takes appropriate action. The Bank has not experienced any credit losses on advances since it was founded in 1932 and, based on its credit extension and collateral policies, management currently does not anticipate any credit losses on advances. Accordingly, the Bank has not provided any allowance for losses on advances.

Short-Term Liquidity Holdings
At June 30, 2021, the Bank’s short-term liquidity holdings were comprised of $6.3 billion of overnight reverse repurchase agreements, $3.5 billion of overnight federal funds sold, $2.6 billion of U.S. Treasury Bills, $0.6 billion of overnight interest-bearing deposits, $0.1 billion of U.S. Treasury Notes and $0.1 billion of excess cash held at the Federal Reserve. At December 31, 2020, the Bank’s short-term liquidity holdings were comprised of $2.9$3.3 billion of U.S. Treasury Bills, $3.1 billion of excess cash held at the Federal Reserve, $1.9 billion of U.S. Treasury Notes, $1.0 billion of overnight reverse repurchase agreements, $0.9 billion of overnight federal funds sold $2.9 billion of U.S. Treasury Notes, $2.9 billion of U.S. Treasury Bills, $2.5 billion of overnight reverse repurchase agreements and $2.0$0.8 billion of overnight interest-bearing deposits.

The credit ratings presented in the two preceding sentences represent the lowest long-term rating assigned to the counterparty by Moody’s or S&P.
The amount of the Bank’s short-term liquidity holdings fluctuates in response to several factors, including the anticipated demand for advances, the timing and extent of advance maturities and prepayments, changes in the Bank’s deposit balances, the Bank’s pre-funding activities, prevailing conditions (or anticipated changes in conditions) in the short-term debt markets, changes in the returns provided by short-term investment alternatives relative to the Bank’s discount note funding costs, the level of liquidity needed to satisfy Finance Agency requirements and the Finance Agency's expectations with regard to the Bank's core mission achievement. For a discussion of the Finance Agency’s liquidity requirements, see the section below entitled “Liquidity and Capital Resources.” For a discussion of the Finance Agency's guidance regarding core mission achievement, see Item 1 - Business - Core Mission Achievement in the 20192020 10-K. For the six months ended June 30, 2020,2021, the Bank's core mission asset ("CMA") ratio was 67.866.2 percent.

The Bank did not acquire or sell any long-term investments during the six months ended June 30, 2020.2021. During the six months ended June 30, 2020, the2021, proceeds from maturities and paydowns of held-to-maturity securities and available-for-sale securities totaled approximately $124$160 million and $152$131 million, respectively.
The Bank is precluded by regulation from purchasing additional MBS if such purchase would cause the aggregate amortized historical cost of its MBS holdings to exceed 300 percent of the Bank’s total regulatory capital (the sum of its capital stock, mandatorily redeemable capital stock and retained earnings). However, the Bank is not required to sell any mortgage securities that it purchased at a time when it was in compliance with this ratio. AtFor purposes of applying this limit, the Finance Agency defines "amortized historical cost" as the sum of the initial investment, less the amount of cash collected that reduces principal, less write-downs plus yield accreted to date. This definition excludes hedge basis adjustments which, for investment securities, are included in the U.S. GAAP definition of amortized cost basis. Under this definition, the Bank's MBS holdings totaled $10.8 billion as of June 30, 2020, the Bank held $12.4 billion (amortized cost) of MBS,2021, which represented 326301 percent of its total regulatory capital as ofat that date. The Bank has not purchased any MBS since September 2019 and it does not intend to purchase additional MBS until such time that it has achieved, and is reasonably confident that it can maintain, a CMA ratio of 70 percent.
On August 12, 2020, the Finance Agency informed the Bank that it had incorrectly interpreted and applied the provisions of the investment regulation that relate to the calculation of MBS purchasing capacity. Based on this finding, the Finance Agency determined that the Bank exceeded its capacity to purchase MBS in June, August and September 2019. The Finance Agency has indicated that it will not require the Bank to sell any of its MBS holdings as a result of this determination.
As discussed in the section entitled "Potential LIBOR Phase-Out" beginning on page 62 of this report, the FHLBanks were directed by the Finance Agency to no longer purchase (after December 31, 2019) LIBOR-indexed investments which mature after December 31, 2021 and (by March 31, 2020) to no longer issue, make, purchase or otherwise enter into financial liabilities, derivatives or other assets that reference LIBOR and which mature after December 31, 2021. In light of the market volatility caused by the COVID-19 pandemic, the Finance Agency (on March 16, 2020) extended the date after which the FHLBanks can no longer issue, make, purchase or otherwise enter into financial liabilities, derivatives or other assets that reference LIBOR and which mature after December 31, 2021 from March 31, 2020 to June 30, 2020, except for option-embedded products. This directive did not in any way modify the previous guidance relating to investments. As a result of this guidance, the Bank's consideration of future fixed-rate MBS purchases will take into account its ability to prudently mitigate interest rate risk through the use of consolidated obligations or derivatives that are indexed to an interest rate other than LIBOR.
In addition to MBS, the Bank is also permitted under applicable policies and regulations to purchase certain other types of highly rated, long-term, non-MBS investments subject to certain limits. These investments include but are not limited to the

non-MBS debt obligations of other GSEs. The Bank has not purchased any long-term, non-MBS investments since October 2019 and it does not intend to purchase additional long-term, non-MBS investments until such time that it has achieved, and is reasonably confident that it can maintain, a CMA ratio of 70 percent. The hedging considerations
As further discussed in the preceding paragraphsection entitled "LIBOR Phase-Out" beginning on page 61 of this report, the Bank is no longer permitted to, among other things, purchase LIBOR-indexed investments which mature after December 31, 2021 or enter into financial liabilities or derivatives that reference LIBOR and which mature after December 31, 2021. As a result of this limitation, the Bank's consideration of future fixed-rate MBS and/or non-MBS purchases will also applytake into account its ability to any fixed-rate non-MBS investmentsprudently mitigate interest rate risk through the use of consolidated obligations or derivatives that are considered for purchase in the future.indexed to an interest rate other than LIBOR (e.g., SOFR).
The Bank evaluates all outstanding available-for-sale securities in an unrealized loss position and all outstanding held-to-maturity securities as of the end of each calendar quarter to determine whether an allowance is needed to reserve for expected credit losses on the securities. As of June 30, 2020,2021, the Bank determined that an allowance for credit losses was not necessary on any of its held-to-maturity or available-for-sale securities. For a summary of the Bank's evaluation, see “Item 1. Financial Statements” (specifically, Note 9 beginning on page 16 of this report).
As of June 30, 2020,2021, the U.S. government and the issuers of the Bank's holdings of GSE debentures and GSE MBS were rated triple-A by Moody's and AA+ by S&P. At that same date, the Bank's holdings of other debentures, which were comprised of securities issued by the Private Export Funding Corporation ("PEFCO"), were rated triple-A by Moody's.

At June 30, 2020,2021, the Bank’s portfolio of non-agency RMBS was comprised of 3 securities with an aggregate unpaid principal balance of $7$5 million that are backed by first lien fixed-rate loans and 19 securities with an aggregate unpaid principal balance of $56$44 million that are backed by first lien option adjustable-rate mortgage (“option ARM”) loans. In comparison, as of December 31, 2019,2020, the Bank’s portfolio of non-agency RMBS was comprised of 3 securities backed by fixed-rate loans that had an aggregate unpaid principal balance of $8$6 million and 19 securities backed by option ARM loans that had an aggregate unpaid principal balance of $62$50 million. A summary of the Bank’s non-agency RMBS as of December 31, 2019 by classification by the originator at the time of issuance and collateral type is presented in the 2019 10-K; there were no material changes to this information during the six months ended June 30, 2020.
While substantially all of the Bank's RMBS portfolio is comprised of collateralized mortgage obligations ("CMOs") with variable-rate coupons ($1.00.6 billion par value at June 30, 2020)2021) that do not expose it to interest rate risk if interest rates rise moderately, these securities include caps that would limit increases in the variable-rate coupons if short-term interest rates rise above the caps. In addition, if interest rates rise, prepayments on the mortgage loans underlying the securities would likely decline, thus lengthening the time that the securities would remain outstanding with their coupon rates capped. As of June 30, 2020,2021, one-month LIBOR was 0.160.10 percent and the effective interest rate caps on one-month LIBOR (the interest cap rate minus the stated spread on the coupon) embedded in the CMO floaters ranged from 5.95 percent to 10.7310.46 percent. The largest concentration of embedded effective caps ($0.80.5 billion) was between 6.00 percent and 6.506.5 percent. As of June 30, 2020,2021, one-month LIBOR rates were 579585 basis points below the lowest effective interest rate cap embedded in the CMO floaters. To hedge a portion

Table of the potential cap risk embedded in these securities, the Bank held one $500 million interest rate cap with a strike rate of 6.50 percent and final maturity in August 2021. The notional balance of this cap declines by $250 million in August 2020 to $250 million. If three-month LIBOR rises above 6.50 percent, the Bank will be entitled to receive interest payments according to the terms and conditions of the interest rate cap agreement. These payments would be based upon the notional amount of the agreement (at that time) and the difference between 6.50 percent and three-month LIBOR.Contents
Mortgage Loans Held For Portfolio
As of June 30, 20202021 and December 31, 2019,2020, mortgage loans held for portfolio (net of allowance for credit losses) were $4.0$3.2 billion and $4.1$3.4 billion, respectively, representing approximately 5.45.5 percent and 5.3 percent, respectively, of the Bank’s total assets at each of those dates. Through the MPF program, the Bank currently invests in only conventional residential mortgage loans originated by its Participating Financial Institutions ("PFIs"). During the period from 1998 to mid-2003, the Bank purchased conventional mortgage loans and government-guaranteed/insured mortgage loans (i.e., those insured or guaranteed by the Federal Housing Administration or the Department of Veterans Affairs). The Bank resumed acquiring conventional mortgage loans under this program in early 2016. Approximately $3.927$3.131 billion of the $3.939$3.140 billion (unpaid principal balance) of mortgage loans on the Bank's balance sheet at June 30, 20202021 were conventional loans, almost all of which were acquired since 2016. The remaining $12$9 million (unpaid principal balance) of the mortgage loan portfolio is comprised of government-guaranteed or government-insured loans that were acquired during the period from 1998 to mid-2003.
During the three and six months ended June 30, 2021, the Bank acquired mortgage loans totaling $368 million ($360 million unpaid principal balance) and $548 million ($537 million unpaid principal balance), respectively. In comparison, the Bank acquired mortgage loans totaling $165 million ($159 million unpaid principal balance) and $592 million ($573 million unpaid principal balance) during the three and six months ended June 30, 2020. All of the acquired mortgage loans were originated by certain of the Bank's PFIs and the Bank acquired a 100 percent interest in such loans. The Bank’s mortgage loan purchases declined significantly beginning in the second quarter of 2020 as pricing became less attractive in the wake of the Federal Reserve's response to the COVID-19 pandemic. As pricing improved somewhat during the second quarter of 2021, the Bank's mortgage loan purchases increased, albeit not to the levels that existed immediately prior to the onset of the COVID-19 pandemic. With the significant decline in mortgage interest rates since the onset of the COVID-19 pandemic, mortgage prepayment activity has remained relatively high. During the three and six months ended June 30, 2021, mortgage loan prepayments totaled $0.3 billion and $0.7 billion, respectively, compared to $0.4 billion and $0.6 billion for the three and six months ended June 30, 2020.
The Bank manages the liquidity, interest rate and prepayment risk of these loans, while the PFIs or their designees retain the servicing activities. The Bank and the PFIs share in the credit risk of the loans with the Bank assuming a limited first loss obligation defined as the First Loss Account (“FLA”), and the PFIs assuming credit losses in excess of the FLA, up to the amount of the required credit enhancement obligation ("CE Obligation") as specified in the master agreement (“Second Loss
54

Table of Contents```
Credit Enhancement”). The FLA is a memo account that is used to track the Bank's exposure to losses until the CE Obligation is available to cover losses. The CE Obligation is the amount of credit enhancement needed for a master commitment to have an estimated rating that is equivalent to an investment grade rated MBS. Credit enhancement levels are set by the Bank using an NRSRO model and are currently set at a triple-B equivalent. The Bank assumes all losses in excess of the Second Loss Credit Enhancement.
Under the Finance Agency’s Acquired Member Asset regulation (12 C.F.R. part 1268), any portion of the CE Obligation that is a PFI’s direct liability must be collateralized by the PFI in the same way that advances are collateralized. Accordingly, the PFI Agreement provides that the PFI’s obligations under the PFI Agreement are secured along with other obligations of the PFI under its regular advances agreement with the Bank and, further, that the Bank may request additional collateral to secure the PFI’s obligations. PFIs are paid credit enhancement fees (“CE fees”) as compensation for retaining a portion of the credit risk on the loans sold to the Bank, as an incentive to minimize credit losses on those loans, to share in the risk of loss on MPF loans and, in limited cases related to loans acquired prior to 2016, to pay for supplemental mortgage insurance, rather than paying a guaranty fee to other secondary market purchasers. CE fees are paid monthly and are determined based on the remaining unpaid principal balance of the MPF loans during the applicable month. CE fees are recorded as a reduction to mortgage loan interest income when paid by the Bank. Mortgage loan interest income was reduced by CE fees totaling $622,000$454,000 and $509,000$622,000 during the three months ended June 30, 20202021 and 2019,2020, respectively, and $1,264,000$944,000 and $961,000$1,264,000 during the six months ended June 30, 20202021 and 2019,2020, respectively. The Bank's allowance for loan losses, which factors in the CE obligation, was $4,892,000$3,487,000 and $1,149,000$3,925,000 at June 30, 20202021 and December 31, 2019,2020, respectively.
For the Bank's conventional loans, the loan payment forbearance is offered to borrowers impacted by COVID-19COVID-19. The forbearance allows a borrower to defer loan payments for 90 days3 months without requiring documentation from the borrower to support the requested relief. Borrowers that continue to be impacted by COVID-19 may request an extension of the loan payment forbearance for up to an additional 270 days.15 months. A hardship certification from the borrower supporting the continued hardship due to COVID-19 is required for approval of additional payment forbearance. During forbearance, late fees are not assessed. At the end of forbearance, borrowers are presented with options for bringing their mortgage loan to a current status. For further discussion, see “Item 1. Financial Statements” (specifically, Note 9 beginning on page 16 of this report).
During the six months ended June 30, 2020, the Bank acquired mortgage loans totaling $592 million ($573 million unpaid principal balance). All of the acquired mortgage loans were originated by certain of the Bank's PFIs and the Bank acquired a 100 percent interest in such loans. The Bank’s mortgage loan purchases have declined significantly since the onset of the COVID-19 pandemic and are not expected to increase again until market conditions improve. Over time, the Bank expects to increase the balance of its mortgage loan portfolio to an amount that approximates 10 percent to 15 percent of its total assets. Currently, the Bank intends to continue to acquire a 100 percent interest in the mortgage loans that it purchases from its PFIs.

During the first six months of 2020,2021, the Bank issued $20.3$27.5 billion of consolidated obligation bonds and approximately $79.6$18.7 billion of consolidated obligation discount notes (excluding those with overnight terms), the proceeds of which were used primarily to replace maturing or called consolidated obligation bonds and maturing discount notes and to fund the increase in the Bank's advances in March and April 2020.notes. At June 30, 20202021 and December 31, 2019,2020, discount notes comprised approximately 5221 percent and 4937 percent, respectively, of the Bank's total outstanding consolidated obligations. During the six months ended June 30, 2020,2021, the Bank's bond issuance (based on trade date and par value) consisted of approximately $14.4 billion of variable-rate bonds, $5.6$23.7 billion of swapped fixed-rate callable bonds (including step-up bonds), and $0.1$4.1 billion of fixed-rate non-callable bonds (which were not swapped)., and $0.1 billion of SOFR-indexed non-callable bonds.
The weighted average cost of swapped and variable-rate consolidated obligation bonds issued by the Bank approximated LIBOR minus 4020 basis points during the three months ended June 30, 2020,2021, compared to LIBOR minus 18 basis points during the three months ended March 31, 20202021 and LIBOR minus 1340 basis points during the three months ended June 30, 2019. The decrease in2020. During the second quarter of 2020, the cost of consolidated bonds relative to LIBOR in the second quarter of 2020 wasdecreased markedly, primarily due to a substantial decrease in the cost of short-term bonds in combination with the elevated LIBOR rates that existed early in thethat quarter. In addition, beginning in March 2020, in response to the COVID-19 outbreak, investor demand for high credit quality, fixed income investments, including the FHLBanks' consolidated obligations, generally increased relative to other investments. However, during that period, the spreads on FHLBank fixed-rate consolidated obligations widened relative to U.S. Treasury securities and fixed income market conditions became more challenging, with market participants favoring shorter-term obligations, including FHLBank discount notes. As conditions in the liquidity markets stabilized, the cost of the Bank's debt returned to approximately pre-pandemic levels by the end of the third quarter of 2020 and has remained relatively stable since that time.
Demand and term deposits were $2.5 billion and $1.3$1.6 billion at both June 30, 20202021 and December 31, 2019, respectively.2020. The size of thethe Bank’s deposit base varies as market factors change, including the attractiveness of the Bank’s deposit pricing relative to the rates available to members on alternative money market investments, members’ investment preferences with respect to the maturity of their investments, and member liquidity.

TheIf, at the time of funding an advance that would otherwise be eligible for the reduced capital stock investment requirement, the then outstanding balance of advances made pursuant to this offering totals $5 billion, then the standard capital stock investment requirement of 4.1 percent will apply. Except as described in this paragraph, the standard activity-based stock investment requirement of 4.1 percent continues to apply to all other advances that are funded during this period.the period from April 1, 2020 through December 31, 2021.

The amended Capital Plan provides for the imposition of an activity-based investment requirement ranging from 0.10 percent to 2.0 percent of members' outstanding letters of credit (the "LC Percentage"), as specified from time to time by the Bank's Board of Directors. The Board of Directors has established an LC Percentage of 0.10 percent which applies only to letters of credit that are issued or renewed on and after April 19, 2021. The LC Percentage is applied to the issued amount of the letter of credit rather than, if applicable, the amount of the letter of credit that is used from time to time during the term of the letter of credit. Further, renewals for this purpose include amendments that extend the expiration date of the letter of credit.

Excess capital stock is defined as the amount of stock held by a member (or former member) in excess of that institution’s minimum investment requirement. The portion of members’ excess capital stock subject to repurchase is known as surplus stock. For the repurchases that occurred during the six months ended June 30, 2020,2021, surplus stock was defined as the amount of stock held by a member shareholder in excess of 125 percent of the shareholder’s minimum investment requirement. For those repurchases, which occurred on March 27, 202029, 2021 and June 26, 2020,25, 2021, a shareholder's surplus stock was not repurchased if: (1) the amount of that shareholder's surplus stock was $2,500,000$2,000,000 or less; (2) the shareholder elected to opt-out of the repurchase; or (3) the shareholder was on restricted collateral status (subject to certain exceptions). On March 27, 202029, 2021 and June 26, 2020,25, 2021, the Bank repurchased surplus stock totaling $139.1$56.9 million and $184.4$35.8 million, respectively, none of which was classified as mandatorily redeemable capital stock at those dates.that date.

During this same period, the Bank paid dividends on capital stock totaling $27.4$7.2 million, which represented a weighted average annualized dividend rate of 2.190.69 percent. These dividends were paid in the form of capital stock with any fractional shares paid in cash. The Bank’s first quarter dividends on Class B-1 Stock and Class B-2 Stock were paid at annualized rates of 1.790.15 percent (a rate equal to average one-month LIBOR for the fourth quarter of 2019)2020) and 2.791.15 percent (a rate equal to average one-month LIBOR for the fourth quarter of 20192020 plus 1.0 percent), respectively. The first quarter dividends, which were applied to average Class B-1 Stock and average Class B-2 Stock held during the period from October 1, 20192020 through December 31, 2019,2020, were paid on March 30, 2020.2021.

The target range for quarterly dividends on Class B-2 Stock during the remainder of 2020 atis currently an annualized rates equal torate that approximates average one-month LIBOR for the applicable dividend periodspreceding quarter plus 1.00.5-1.0 percent.
The Bank is required to maintain at all times permanent capital in an amount at least equal to its risk-based capital requirement, which is the sum of its credit risk capital requirement, its market risk capital requirement, and its operations risk capital requirement, as further described in the 20192020 10-K. Permanent capital is defined under the Finance Agency’s rules as retained earnings and amounts paid in for Class B stock (which for the Bank includes both Class B-1 Stock and Class B-2 Stock), regardless of its classification as equity or liabilities for financial reporting purposes. At June 30, 2020,2021, the Bank’s total risk-based capital requirement was $1.038$1.016 billion, comprised of credit risk, market risk and operations risk capital requirements of $286$198 million, $513$584 million and $239$234 million, respectively, and its permanent capital was $3.820$3.576 billion.
In addition to the risk-based capital requirement, the Bank is subject to three other capital requirements. First, the Bank must, at all times, maintain a minimum total capital-to-assets ratio of 4.0 percent. For this purpose, total capital is defined by Finance Agency rules and regulations as the Bank’s permanent capital and the amount of any general allowance for losses (i.e., those reserves that are not held against specific assets). Second, the Bank is required to maintain at all times a minimum leverage capital-to-assets ratio in an amount at least equal to 5.0 percent of its total assets. In applying this requirement to the Bank, leverage capital includes the Bank’s permanent capital multiplied by a factor of 1.5 plus the amount of any general allowance for losses. The Bank did not have any general allowance for losses at June 30, 20202021 or December 31, 2019.2020. Under the regulatory definitions, total capital and permanent capital exclude accumulated other comprehensive income (loss). Third, beginning in February 2020, the Bank is required to maintain a capital stock-to-assets ratio of at least 2.0 percent, as measured

on a daily average basis at each month end. At all times during the six months ended June 30, 2020,2021, the Bank was in compliance with all of its regulatory capital requirements. At June 30, 2020,2021, the Bank's total capital-to-assets and leverage capital-to-assets ratios were 5.106.10 percent and 7.649.15 percent, respectively. The Bank's capital stock-to-assets ratio was 3.443.61 percent for the month ended June 30, 2020.2021. For a summary of the Bank’s compliance with the Finance Agency’s capital requirements as of June 30, 20202021 and December 31, 2019,2020, see “Item 1. Financial Statements” (specifically, Note 14 on page 3332 of this report).
Derivatives and Hedging Activities
The Bank enters into interest rate swap, swaption, cap floor and forward ratefloor agreements (collectively, interest rate exchange agreements) to manage its exposure to changes in interest rates and/or to adjust the effective maturity, repricing index and/or frequency or option characteristics of financial instruments. This use of derivatives is integral to the Bank’s financial management strategy, and the impact of these interest rate exchange agreements permeates the Bank’s financial statements. For additional discussion, see “Item 1. Financial Statements” (specifically, Note 13 beginning on page 2524 of this report).

As a result of statutory and regulatory requirements emanating from the Dodd-Frank Wall Street Reform and Consumer Protection Act (the "Dodd-Frank Act"), certain derivative transactions that the Bank enters into are required to be cleared through a third-party central clearinghouse. As of June 30, 2020,2021, the Bank had cleared trades outstanding with notional amounts totaling $31.8$23.5 billion. Cleared trades are subject to initial and variation margin requirements established by the clearinghouse and its clearing members. Collateral (or variation margin on daily settled derivative contracts) is typically delivered/paid (or returned/received) daily and, unlike bilateral derivatives, is not subject to any maximum unsecured credit exposure thresholds. The fair values of all interest rate derivatives (including accrued interest receivables and payables) with each clearing member of each clearinghouse are offset for purposes of measuring credit exposure and determining initial and variation margin requirements. With cleared transactions, the Bank is exposed to credit risk in the event that the clearinghouse or the clearing member fails to meet its obligations to the Bank. The Bank has determined that the exercise by a non-defaulting party of the setoff rights incorporated in its cleared derivative transactions should be upheld in the event of a default, including a bankruptcy, insolvency or similar proceeding involving the clearinghouse or any of its clearing members or both.

The Bank has transacted some of its interest rate exchange agreements bilaterally with large financial institutions (with which it has in place master agreements). In doing so, the Bank has generally exchanged a defined market risk for the risk that the counterparty will not be able to fulfill its obligations in the future. The Bank manages this credit risk by spreading its transactions among as many highly rated counterparties as is practicable, by entering into master agreements with each of its non-member bilateral counterparties that include maximum unsecured credit exposure thresholds ranging from $50,000 to $500,000, and by monitoring its exposure to each counterparty on a daily basis. In addition, all of the Bank’s master agreements with its bilateral counterparties include netting arrangements whereby the fair values of all interest rate derivatives (including accrued interest receivables and payables) with each counterparty are offset for purposes of measuring credit exposure. As of June 30, 2020,2021, the notional balancesbalance of outstanding interest rate exchange agreements transacted with non-member bilateral counterparties totaled $14.9$27.7 billion.
Under the Bank’s master agreements with its non-member bilateral counterparties, the unsecured credit exposure thresholds must be met before collateral is required to be delivered by one party to the other party. Once the counterparties agree to the

Table of Contents
valuations of the interest rate exchange agreements, and if it is determined that the unsecured credit exposure exceeds the threshold, then, upon a request made by the unsecured counterparty, the party that has the unsecured obligation to the counterparty bearing the risk of the unsecured credit exposure generally must deliver sufficient collateral (or return a sufficient amount of previously remitted collateral) to reduce the unsecured credit exposure to zero (or, in the case of pledged securities, to an amount equal to the discount applied to the securities under the terms of the master agreement). Collateral is delivered (or returned) daily when these thresholds are met. The master agreements with the Bank's non-member bilateral counterparties require the delivery of collateral consisting of cash or very liquid, highly rated securities (generally consisting of U.S. government-guaranteed or agency debt securities) if credit risk exposures rise above the thresholds.
The notional amount of interest rate exchange agreements does not reflect the Bank’s credit risk exposure, which is much less than the notional amount. The Bank's net credit risk exposure is based on the current estimated cost, on a present value basis, of replacing at current market rates all interest rate exchange agreements with individual counterparties, if those counterparties were to default, after taking into account the value of any cash and/or securities collateral held or remitted by the Bank. For counterparties with which the Bank is in a net gain position, the Bank has credit exposure when the collateral it is holding (if any) has a value less than the amount of the gain. For counterparties with which the Bank is in a net loss position, the Bank has credit exposure when it has delivered collateral with a value greater than the amount of the loss position.

The Bank offers interest rate swaps, caps and floors to its members to assist them in meeting their risk management objectives. In derivative transactions with its members, the Bank acts as an intermediary by entering into an interest rate exchange agreement with the member and then entering into an offsetting interest rate exchange agreement with one of the Bank’s non-member derivative counterparties discussed above. When entering into interest rate exchange agreements with its members, the Bank requires the member to post eligible collateral in an amount equal to the sum of the net market value of the member’s derivative transactions with the Bank (if the value is positive to the Bank) plus a percentage of the notional amount of any interest rate swaps, with market values determined on at least a monthly basis. Eligible collateral for derivative transactions consists of collateral that is eligible to secure advances and other obligations under the member’s Advances and Security Agreement with the Bank.
The Dodd-Frank Act changed the regulatory framework for derivative transactions that are not subject to mandatory clearing requirements (uncleared trades). While the Bank expects to be able in certain instances to continue to enter into uncleared trades on a bilateral basis, those transactions will be subject to new regulatory requirements, including (if certain thresholds are met) minimum initial margin requirements imposed by regulators. For additional discussion, see the section entitled "Legislative and Regulatory Developments" on page 47 of this report.in Item 1. Business in the 2020 10-K.

Potential LIBOR Phase-Out
As discussed in "Item 1A — Risk Factors” inIn July 2017, the 2019 10-K,United Kingdom’s Financial Conduct Authority ("FCA") announced that it intended to stop persuading or compelling banks to voluntarily submit LIBOR mayrates after 2021, and that the FCA would support the LIBOR indices through 2021 to allow for an orderly transition to an alternative reference rate (or rates). On March 5, 2021, the FCA announced the dates that panel bank submissions for all LIBOR settings will cease, after which representative LIBOR rates will no longer be available. While the FCA confirmed that many LIBOR settings will either cease to be availableprovided by any administrator or no longer be representative immediately after December 31, 2021. Consequently,2021, one-month and three-month U.S. dollar LIBOR, the settings that apply to the Bank's LIBOR-indexed financial instruments, will either cease to be provided by any administrator or no longer be representative immediately after June 30, 2023. Although the FCA does not expect one-month and three-month U.S. dollar LIBOR to become unrepresentative before June 30, 2023 and it intends to consult on requiring the administrator of LIBOR to continue publishing one-month and three-month U.S. dollar LIBOR on a non-representative, synthetic basis for a period after June 30, 2023, there is no assurance that these LIBOR rates will continue to be published or be representative through any particular date.
For some time, the Bank has begunbeen preparing for this possibility and the associated transition to an alternative reference rate (e.g., SOFR). Among other things, a permanent discontinuation of LIBOR will necessitatehas necessitated the addition of fallback language in the Bank's LIBOR-indexed derivative contracts extendingthat extend past 2021 that reference LIBOR,the cessation date, as well as changes in the Bank's risk management practices. In response to the potentialprobable future cessation of LIBOR, the Bank is no longer offering LIBOR-indexed advances, with maturities after December 31, 2021, nor is it issuing LIBOR-indexed consolidated obligations with maturities after that date.obligations.
On September 27, 2019, the Finance Agency issued a supervisory letter to the FHLBanks relating to their preparations for the potential phase-out of LIBOR after December 31, 2021.LIBOR. Under the supervisory letter, with limited exceptions, the FHLBanks were directed, by December 31, 2019, to no longer purchase LIBOR-indexed investments which mature after December 31, 2021 and, by March 31, 2020, to no longer issue, make, purchase or otherwise enter into financial liabilities, derivatives or other assets that reference LIBOR and which mature after December 31, 2021. In light of the market volatility that was caused by the COVID-19 pandemic, the Finance Agency (on March 16, 2020) extended the date after which the FHLBanks cancould no longer issue, make, purchase or otherwise enter into financial liabilities, derivatives or other assets that reference LIBOR and which mature after December 31, 2021 from March 31, 2020 to June 30, 2020, except for option-embedded products. This directive did not in any way modify the previous guidance relating to investments. As directed byThe Bank has complied with all aspects of this guidance.
On October 23, 2020, ISDA launched the Finance Agency,IBOR Fallbacks Supplement (“Supplement”) and the Bank no longer purchases LIBOR-indexed investments which mature after December 31, 2021 (nor does it purchase fixedIBOR Fallbacks Protocol (“Protocol”). The Supplement amends ISDA’s standard definitions for interest rate investments which mature afterderivatives to incorporate robust fallbacks for derivatives linked to certain interbank offered rates (“IBORs”). Both the Supplement and the Protocol took effect on January 25, 2021. On that date, all legacy bilateral derivative transactions subject to Protocol-covered agreements (including ISDA agreements) that are hedged with LIBOR-indexed derivatives). Beginning July 1, 2020 (or,incorporate certain covered ISDA definitional booklets and reference a covered IBOR, including LIBOR, were amended to apply the new ISDA-recommended IBOR fallbacks in the event of the relevant IBOR’s cessation. Both parties must adhere to the Protocol in order to effectively amend legacy derivative contracts or, alternatively, the parties must bilaterally agree to amended legacy contracts to address IBOR fallbacks. The Bank and all of its non-member bilateral derivative counterparties have adhered to the Protocol. On and after January 25, 2021, all new derivative contracts will be subject to the relevant IBOR fallbacks set forth in the Supplement. ISDA has stated that the FCA's announcement on March 5, 2021 constitutes an index cessation event under the Supplement and the Protocol and, as a result, the fallback spread adjustment published by Bloomberg was fixed as of the date of that announcement for certain financial instruments with embedded options, April 1, 2020), the Bank no longer issues, makes, purchases or otherwise enters into financial liabilities, other derivatives or other assets that referenceall LIBOR and which mature after December 31, 2021.settings.

Results of Operations
Net Income
Net income for the three months ended June 30, 2021 and 2020 and 2019 was $67.0$28.0 million and $54.1$67.0 million, respectively. The Bank’s net income for the three months ended June 30, 20202021 represented an annualized return on average capital stock (“ROCS”) of 9.685.39 percent. In comparison, the Bank’s ROCS was 8.539.68 percent for the three months ended June 30, 2019.2020. Net income for the six months ended June 30, 2021 and 2020 and 2019 was $118.5$75.9 million and $112.5$118.5 million, respectively. The Bank’s net income for the six months ended June 30, 20202021 represented an annualized ROCS of 9.027.43 percent. In comparison, the Bank’s ROCS was 8.909.02 percent for the six months ended June 30, 2019.2020. To derive the Bank’s ROCS, net income is divided by average capital stock outstanding excluding stock that is classified as mandatorily redeemable capital stock. The factors contributing to the changes in the Bank's net income are discussed below.
Income Before Assessments

Net Interest Income After Provision for Mortgage Loan Losses
For the three months ended June 30, 2020,2021, the Bank’s net interest income (after provision for mortgage loan losses) was $110.1$51.2 million compared to $62.5$110.1 million for the comparable period in 2019.2020. The $47.6$58.9 million increasedecrease in net interest income for the three months ended June 30, 2020,2021, as compared to the corresponding period in 2019,2020, was due in partlargely to a $25.0decrease in the average balances of the Bank's interest-earning assets, as well as a $15.2 million unfavorable change in fair value hedge ineffectiveness from period to period. The Bank's average balance of interest-earning assets decreased from $84.7 billion during the three months ended June 30, 2020 to $58.9 billion during the comparable period in 2021.
For the six months ended June 30, 2021, the Bank’s net interest income (after provision for mortgage loan losses) was $131.2 million compared to $155.7 million for the comparable period in 2020. The $24.5 million decrease in net interest income for the six months ended June 30, 2021, as compared to the corresponding period in 2020, was due largely to a decrease in the average balances of the Bank's interest-earning assets from $78.8 billion during the six months ended June 30, 2020 to $59.2 billion during the comparable period in 2021. Net interest income was positively impacted by a $41.2 million favorable change in fair value hedge ineffectiveness from period to period (which, as further discussed below, is largely offset by mitigation activities undertaken by the Bank, the results of which are recorded in other income/loss), an increase in the Bank's net interest spread (primarily due to lower debt costs) and an increase in the average balances of the Bank's interest-earning assets. The Bank's average balance of interest-earning assets increased from $69.3 billion during the three months ended June 30, 2019 to $84.7 billion during the comparable period in 2020.
For the six months ended June 30, 2020, the Bank’s net interest income (after provision for mortgage loan losses) was $155.7 million compared to $134.5 million for the comparable period in 2019. The $21.2 million increase in net interest income for the six-month period ended June 30, 2020, as compared to the corresponding period in 2019, was due primarily to an increase in the average balances of the Bank's interest-earning assets and an increase in the Bank's net interest spread (primarily due to lower debt costs). The impact of these factors was partially offset by a $2.5 million unfavorable change in fair value hedge ineffectiveness from period to period (which, as further discussed below, is largely offset by mitigation activities undertaken by the Bank, the results of which are recorded in other income/loss) and a $1.3 million increase in the provision for mortgage loan losses, which was primarily due to an increase in expected credit losses as a result of the COVID-19 pandemic. The Bank's average balance of interest-earning assets increased from $68.7 billion during the six months ended June 30, 2019 to $78.8 billion during the comparable period in 2020.
For the three months ended June 30, 20202021 and 2019,2020, the Bank’s net interest margin was 5334 basis points and 3653 basis points, respectively. The Bank’s net interest margin was 4044 basis points and 3940 basis points for the six months ended June 30, 20202021 and 2019,2020, respectively. Net interest margin, or net interest income as a percentage of average earning assets, is a function of net interest spread and the rates of return on assets funded by the investment of the Bank’s capital. Net interest spread is the difference between the yield on interest-earning assets and the cost of interest-bearing liabilities. The Bank’s net interest spread was 4933 basis points and 2149 basis points for the three months ended June 30, 20202021 and 2019,2020, respectively, and 3443 basis points and 2434 basis points for the six months ended June 30, 20202021 and 2019,2020, respectively. The Bank's net interest margin and net interest spread are impacted positively or negatively, as the case may be, by the amount of fair value hedge ineffectiveness recorded in net interest income.
Accounting Standards Update 2017-12, "Targeted Improvements to Accounting for Hedging Activities" ("ASU 2017-12"),U.S. GAAP requires that, for fair value hedges, the entire change in the fair value of the hedging instrument included in the assessment of

hedge effectiveness along with the changes in the fair value of the hedged item attributable to the hedged risk be presented in the same income statement line that is used to present the earnings effect of the hedged item. For the three months ended June 30, 2021 and 2020, the fair value hedge ineffectiveness amounts reported in net interest income reduced interest income on advances by $120,000 and 2019,$821,000, respectively, increased (reduced) interest income on available-for-sale securities by $(5,306,000) and $4,579,000, respectively, and increased (reduced) interest expense on consolidated obligations by $331,000 and $(5,665,000), respectively. In aggregate, these amounts increased (reduced) net interest income by $(5,757,000) and $9,423,000 for the three months ended June 30, 2021 and 2020, respectively. For the six months ended June 30, 2021 and 2020, the fair value hedge ineffectiveness amounts reported in net interest income increased (reduced) interest income on advances by $(821,000)$355,000 and $34,000,$(1,686,000), respectively, increased (reduced) interest income on available-for-sale securities by $4,579,000$14,816,000 and $(14,400,000)$(28,689,000), respectively, and increased (reduced) interest expense on consolidated obligations by $(5,665,000)$1,464,000 and $1,259,000,$(2,908,000), respectively. ForIn aggregate, these amounts increased (reduced) net interest income by $13,707,000 and $(27,467,000) for the six months ended June 30, 20202021 and 2019, the fair value hedge ineffectiveness amounts reported in net interest income increased (reduced) interest income on advances by $(1,686,000) and $7,000, respectively, reduced interest income on available-for-sale securities by $28,689,000 and $23,969,000, respectively, and increased (reduced) interest expense on consolidated obligations by $(2,908,000) and $1,003,000,2020, respectively.
The higher yielding, longer duration fixed-rate GSE commercial MBS ("CMBS") and GSE debentures held in the Bank’s available-for-sale securities portfolio (all of which have been hedged with fixed-for-floating interest rate swaps in long-haul hedging relationships) expose the Bank to periodic earnings variability in the form of fair value hedge ineffectiveness. The hedge ineffectiveness gains and losses associated with these particular relationships are attributable in large part to the use of different discount curves to value the interest rate swaps (the(either the overnight index swap curve or the SOFR curve) and the GSE CMBS/GSE debentures (LIBOR plus a constant spread). Notwithstanding the hedge ineffectiveness gains and losses, these hedging relationships have been, and are expected to continue to be, highly effective in achieving offsetting changes in fair values attributable to the hedged risk. While the ineffectiveness-related gains and losses associated with these hedging relationships can be significant when evaluated in the context of the Bank’s net income, they are relatively small when expressed as a percentage of the values of the positions. Because the Bank expects to hold these interest rate swaps to maturity, the unrealized ineffectiveness-related gains (or losses) associated with its holdings of GSE CMBS and GSE debentures are expected to be transitory, meaning that they will reverse in future periods in the form of ineffectiveness-related losses (or gains).
The contribution of earnings from the Bank’s invested capital to the net interest margin (the impact of non-interest bearing funds) declined from 15 basis points during the three and six months ended June 30, 2019 to 4 basis points and 6 basis points during the three and six months ended June 30, 2020, respectively.respectively, to 1

basis point during both the three and six months ended June 30, 2021. The decrease in the impact of non-interest bearing funds for the three and six months ended June 30, 2020,2021, as compared to the corresponding periods in 2019,2020, is primarily due to the decrease in short-term interest rates between the periods.

Net Interest Settlements
Net interest income (expense) associated with economic hedge derivatives including, but not limited to, those associated with non-qualifying fair value hedging relationships is recorded in net gains (losses) on derivatives and hedging activities. Net interest income (expense) associated with derivatives in qualifying fair value hedging relationships is recorded in net interest income in the same income statement line that is used to present the earnings effect of the hedged item.
Fair Value Hedge Ineffectiveness
The Bank uses interest rate swaps to hedge the risk of changes in the fair value of some of its advances and consolidated obligation bonds and, currently, all of its available-for-sale securities. These hedging relationships are designated as fair value hedges. To the extent these relationships qualify for hedge accounting, changes in the fair values of both the derivative (the interest rate swap) and the hedged item (limited to changes attributable to the hedged risk) are recorded in net interest income in the same income statement line that is used to present the earnings effect of the hedged item. To the extent that the Bank's fair

value hedging relationships do not qualify for hedge accounting, or cease to qualify because they are determined to be ineffective, only the change in fair value of the derivative is recorded in earnings as net gains (losses) on derivatives and hedging activities (in this case, there is no offsetting change in fair value of the hedged item). The net gains (losses) on derivatives associated with specific advances, available-for-sale securities and consolidated obligation bonds that did not qualify for hedge accounting, or ceased to qualify because they were determined to be ineffective, totaled $(4,165,000)$38,000 and $(112,000)$(4,165,000) for the three months ended June 30, 20202021 and 2019,2020, respectively, and $(12,135,000)$3,419,000 and $(22,000)$(12,135,000) for the six months ended June 30, 20202021 and 2019,2020, respectively.
Economic Hedge Derivatives
Notwithstanding the transitory nature of the ineffectiveness-related gains and losses associated with the Bank's available-for-sale securities portfolio (discussed above), the Bank has entered into several derivative transactions in an effort to mitigate a portion of the periodic earnings variability that can result from those fair value hedging relationships. At both June 30, 20202021 and December 31, 2019,2020, the notional balance of these derivatives totaled $425 million. For both the three months ended June 30, 20202021 and 2019,2020, the gains associated with these stand-alone economic hedge derivatives were $3.5 million and $14.0 million, respectively.million. For the six months ended June 30, 20202021 and 2019,2020, the gains (losses) associated with these stand-alone economic hedge derivatives were $36.4$(13.4) million and $23.4$36.4 million, respectively.
The Bank has invested in residential mortgage loans. A portion of the interest rate and prepayment risk associated with the Bank's mortgage loan portfolio is managed through the use of interest rate swaps and swaptions. The net change in the fair values of these interest rate swaps and swaptions were gains (losses) of $(0.7)$(4.7) million and $0.6$(0.7) million for the three months ended June 30, 20202021 and 2019,2020, respectively, and gains (losses) of $(2.8)$7.0 million and $0.1$(2.8) million for the six months ended June 30, 20202021 and 2019,2020, respectively. In addition, in some but not all cases, the Bank enters into delivery commitments associated with the purchase of the mortgage loans. The fair value changes associated with mortgage delivery commitments (representing net unrealized gainsgains/losses from the commitment date to the settlement date) were $3.9$(0.7) million and $0.5$3.9 million for the three months ended June 30, 20202021 and 2019,2020, respectively, and $6.3$(1.9) million and $1.8$6.3 million for the six months ended June 30, 20202021 and 2019,2020, respectively.
As discussed previously in the section entitled “Financial Condition — Derivatives and Hedging Activities," the Bank offers interest rate swaps, caps and floors to its members to assist them in meeting their risk management objectives. In derivative transactions with its members, the Bank acts as an intermediary by entering into an interest rate exchange agreement with the member and then entering into an offsetting interest rate exchange agreement with one of the Bank’s non-member derivative counterparties. The net change in the fair values of derivatives transacted with members and the offsetting derivatives was $(23,000)$(12,000) and $235,000$(23,000) for the three months ended June 30, 20202021 and 2019,2020, respectively, and $(30,000)$(25,000) and $274,000$(30,000) for the six months ended June 30, 20202021 and 2019,2020, respectively.
Price Alignment Amount
Effective January 3, 2017, one ofPursuant to their rulebooks, the Bank's two clearinghouse counterparties made certain amendments to its rulebook that changed the legal characterization oflegally characterize variation margin payments on cleared derivatives toas settlements on the contracts. Effective January 16, 2018, the Bank's other clearinghouse counterparty made similar amendments to its rulebook. Prior to the dates upon which these amendments became effective, the variation margin payments were in each case characterized as collateral pledged to secure outstanding credit exposure on the derivative contracts. The Bank receives or pays a price alignment amount on the cumulative variation margin payments associated with these contracts. The price alignment amount approximates the amount of interest the Bank would have receivedreceive or paid hadpay if the variation margin payments continued to bewere characterized as collateral.collateral pledged to secure outstanding credit exposure on the derivative contracts. The price alignment amount associated with derivatives in qualifying fair value hedging relationships is recorded in net interest income in the same income statement line that is used to present the earnings effect of the hedged item. The price alignment amount associated with economic hedge derivatives including, but not limited to, those associated with non-qualifying fair value hedging relationships, is recorded in net gains (losses) on derivatives and hedging activities.
Other
During the three and six months ended June 30, 2019, the Bank sold approximately $24 million2021 and $435 million, respectively, of GSE CMBS classified as available-for-sale securities. The aggregate gains realized on these sales totaled $0.1 million and $0.6 million, respectively. There were no other sales of long-term investments during the six months ended June 30, 2020, or 2019.
During the six months ended June 30, 2020 and 2019, the Bank held U.S. Treasury Bills and U.S. Treasury Notes, all of which were classified as trading securities. Due to fluctuations in interest rates, the aggregate gains (losses) on these investments were $(12.0)$(0.5) million and $4.9$(12.0) million for the three months ended June 30, 20202021 and 2019,2020, respectively, and $21.1$(6.9) million and $8.1$21.1 million for the six months ended June 30, 20202021 and 2019,2020, respectively. The Bank occasionally hedges the risk of changes in the fair value of some of the U.S. Treasury Notes held in its short-term liquidity portfolio. For the three months ended June 30, 20202021 and 2019,2020, the gains (losses) associated with these stand-alone derivatives were $0.5 million and $10.3 million, and $(1.6) million,

respectively. The gains (losses) associated with these stand-alone derivatives were $(12.8)$3.5 million and $(2.2)$(12.8) million for the six months ended June 30, 20202021 and 2019,2020, respectively.
The Bank has a small balance of marketable equity securities consisting solely of mutual fund investments associated with its non-qualified deferred compensation plans. These securities are carried at fair value and included in other assets on the statements of condition. The fair value gains (losses) on these securities totaled $1.4$0.7 million and $0.4$1.4 million for the three months ended June 30, 20202021 and 2019,2020, respectively, and $(0.3)$1.2 million and $1.3$(0.3) million for the six months ended June 30, 2020 2021

The gains or losses(losses) on the securities are offset by a corresponding increase or decrease(decrease) in amounts owed to participants in the deferred compensation plans, the expense (or credit) for which is recorded in compensation and benefits expense (in the case of employees) or other operating expenses (in the case of directors).
Letter of credit fees totaled $3.7$3.6 million and $7.3 million for the three and six months ended June 30, 2020, respectively,2021 compared to $3.0$3.7 million and $5.8$7.3 million for the corresponding periods in 2019. The increase in letter of credit fees for the three and six months ended June 30, 2020, as compared to the corresponding periods in 2019, was due to an increase in the amount of letters of credit outstanding.2020. At June 30, 20202021 and 2019,2020, outstanding letters of credit totaled $22.1$21.4 billion and $19.7$22.1 billion, respectively.
Other Expense
Total other expense includes the Bank’s compensation and benefits; other operating expenses; subsidies, grants and donations; derivative clearing fees; and its proportionate share of the costs of operating the Finance Agency and the Office of Finance. For the three and six months ended June 30, 2020,2021, these expenses totaled $33.1$25.7 million and $56.7$51.0 million, respectively, compared to $24.5$33.1 million and $48.6$56.7 million, respectively, for the corresponding periods in 2019.2020.
Compensation and benefits were $13.6$13.5 million and $25.2$27.2 million for the three and six months ended June 30, 2020,2021, respectively, compared to $12.4$13.6 million and $25.9$25.2 million, respectively, for the corresponding periods in 2019.2020. The $1.2 million increasechanges in compensation and benefits for the threesix months ended June 30, 2020,2021, as compared to the corresponding period in 2019,2020, was due largely to an increasechanges in amounts due to employees under the Bank's non-qualified deferred compensation plans, as well as cost of living and merit increases. The $0.7plans. These expenses were $1.3 million decrease in compensation and benefitshigher for the six months ended June 30, 2020,2021, as compared to the corresponding period in 2019, was2020, due to a decrease in amounts due to employees under the Bank's non-qualified deferred compensation plans, partially offset by cost of living and merit increases and an increase in separation pay. The fluctuations in the amounts due to employees under the Bank's deferred compensation plans were due to fluctuations in the fair value of the assets associated with those plans.plans in 2021 as compared to a decrease in 2020. In addition, compensation expenses increased during the six months ended June 30, 2021, as compared to the corresponding period in 2020 due to higher defined benefit plan expenses, higher medical costs and the impact of cost of living and merit adjustments, which were partially offset by lower employee separation costs. The Bank's average headcount was 201204 and 199201 employees for the six months ended June 30, 20202021 and 2019,2020, respectively. At June 30, 2020,2021, the Bank employed 202204 people, a decreasean increase of 1 employee from December 31, 2019.2020.
Other operating expenses for the three and six months ended June 30, 20202021 were $9.6$8.8 million and $18.8$17.3 million, respectively, compared to $9.6 million and $17.6$18.8 million, respectively, for the corresponding periods in 2019.2020. The increasedecrease in other operating expenses for the three and six months ended June 30, 2020,2021, as compared to the corresponding periodperiods in 2019,2020, resulted primarily from increases inlower professional services,fees, independent contractor costs and transaction services fees associated with the Bank's mortgage loan program, (duepartially offset by an increase in software costs. The decrease in transaction service fees was due to higherlower mortgage loan balances). The transaction servicebalances. These fees are paid to the FHLBank of Chicago as compensation for administering the MPF Program. These increases were partially offset by decreases in legal fees and business travel during the six months ended June 30, 2020, as compared to the corresponding period in 2019.
Subsidies, grants and donations were $7.1$0.2 million and $7.2$0.3 million for the three and six months ended June 30, 2020,2021, respectively, compared to $1,000$7.1 million and $39,000,$7.2 million, respectively, for the corresponding periods in 2019.2020. In response to the COVID-19 pandemic, the Bank made available (during the three months ended June 30, 2020) $5.0 billion of below-market rate (or subsidized) advances at a cost to the Bank of $4.4 million. Further, during this same period, the Bank made $0.9 million in charitable contributions primarily to various food banks throughout the Bank's district and it funded $1.7 million in grants under its Partnership Grant Program, which was expanded to address pandemic relief efforts. During the three and six months ended June 30, 2020, the Bank also funded $86,000 and $232,000, respectively, in grants under its Housing Assistance for Veterans program, which is designed to provide grants to households of veterans or active service members who were disabled as a result of an injury during their active military service since September 11, 2001.
Derivative clearing fees were approximately $0.3 million for both the three months ended June 30, 20202021 and 2019 and $0.72020. Derivative clearing fees were $0.5 million and $0.6$0.7 million for the six months ended June 30, 20202021 and 2019,2020, respectively.
The Bank, together with the other FHLBanks, is assessed for the costs of operating the Office of Finance and a portion of the costs of operating the Finance Agency. The Bank’s allocated share of these expenses totaled approximately $2.5$2.9 million and $4.9$5.6 million for the three and six months ended June 30, 2020,2021, respectively, as compared to $2.2$2.5 million and $4.4$4.9 million, respectively, for the corresponding periods in 2019.2020.

AHP Assessments
While the Bank is exempt from all federal, state and local income taxes, it is obligated to set aside amounts for its Affordable Housing Program (“AHP”).
As required by statute, each year the Bank contributes 10 percent of its earnings (as adjusted for interest expense on mandatorily redeemable capital stock) to its AHP. The AHP provides grants that members can use to support affordable housing projects in their communities. Generally, the Bank’s AHP assessment is derived by adding interest expense on mandatorily redeemable capital stock to income before assessments; the result of this calculation is then multiplied by 10 percent. The Bank’s AHP assessments totaled $7.4$3.1 million and $6.0$7.4 million for the three months ended June 30, 20202021 and 2019,2020, respectively, and $13.2$8.4 million and $12.5$13.2 million for the six months ended June 30, 2021 and 2020, and 2019, respectively.

Critical Accounting Policies and Estimates
A discussion of the Bank’s critical accounting policies and the extent to which management uses judgment and estimates in applying those policies is provided in the 20192020 10-K. There were no substantive changes to the Bank’s critical accounting policies, or the extent to which management uses judgment and estimates in applying those policies, during the six months ended June 30, 2020.2021.
Liquidity and Capital Resources
In order to meet members’ credit needs and the Bank’s financial obligations, the Bank maintains a portfolio of money market instruments typically consisting of overnight federal funds, overnight reverse repurchase agreements, overnight interest-bearing deposits, U.S. Treasury Bills and U.S. Treasury Notes. From time to time, the Bank may also invest in short-term commercial paper and GSE discount notes. Beyond those amounts that are required to meet members’ credit needs and its own obligations, the Bank typically holds additional balances of short-term investments that fluctuate as the Bank invests the proceeds of debt issued to replace maturing and called liabilities, as the balance of deposits changes, as the returns provided by short-term investments vary relative to the costs of the Bank’s discount notes, and as the level of liquidity needed to satisfy Finance Agency requirements changes. At June 30, 2020,2021, the Bank’s short-term liquidity holdings were comprised of $2.9$6.3 billion of overnight reverse repurchase agreements, $3.5 billion of overnight federal funds sold, $2.9$2.6 billion of U.S. Treasury Bills, $0.6 billion of overnight interest-bearing deposits, $0.1 billion of U.S. Treasury Notes $2.9and $0.1 billion of U.S. Treasury Bills, $2.5 billion of overnight reverse repurchase agreements and $2.0 billion of overnight interest-bearing deposits.excess cash held at the Federal Reserve.
The Bank’s primary source of funds is the proceeds it receives from the issuance of consolidated obligation bonds and discount notes in the capital markets. Historically, the FHLBanks have issued debt throughout the business day in the form of discount notes and bonds with a wide variety of maturities and structures. Generally, the Bank has access to the capital markets as needed during the business day to acquire funds to meet its needs.
In addition to the liquidity provided from the proceeds of the issuance of consolidated obligations, the Bank also maintains access to wholesale funding sources such as federal funds purchased and securities sold under agreements to repurchase (e.g., borrowings secured by its investments in U.S. Treasury securities, MBS and/or agency debentures). Furthermore, the Bank has access to borrowings (typically short-term) from the other FHLBanks.
The 11 FHLBanks and the Office of Finance are parties to the Federal Home Loan Banks P&I Funding and Contingency Plan Agreement, as amended and restated effective January 1, 2017 (the “Contingency Agreement”). The Contingency Agreement and related procedures are designed to facilitate the timely funding of principal and interest payments on FHLBank System consolidated obligations in the event that a FHLBank is not able to meet its funding obligations in a timely manner. The Contingency Agreement and related procedures provide for the issuance of overnight consolidated obligations ("Plan COs") directly to one or more FHLBanks that provide funds to avoid a shortfall in the timely payment of principal and interest on any consolidated obligations for which another FHLBank is the primary obligor. The direct placement by a FHLBank of consolidated obligations with another FHLBank is permitted only in those instances when direct placement of consolidated obligations is necessary to ensure that sufficient funds are available to timely pay all principal and interest on FHLBank System consolidated obligations due on a particular day. Through the date of this report, no Plan COs have ever been issued pursuant to the terms of the Contingency Agreement.
On occasion, and as an alternative to issuing new debt, the Bank may assume the outstanding consolidated obligations for which other FHLBanks are the original primary obligors. This occurs in cases where the original primary obligor may have participated in a large consolidated obligation issue to an extent that exceeded its immediate funding needs in order to facilitate better market execution for the issue. The original primary obligor might then warehouse the funds until they were needed, or make the funds available to other FHLBanks. Transfers may also occur when the original primary obligor’s funding needs change, and that FHLBank offers to transfer debt that is no longer needed to other FHLBanks. Transferred debt is typically fixed-rate, fixed-term, non-callable debt, and may be in the form of discount notes or bonds. The Bank participates in such transfers of funding from other FHLBanks when the transfer represents favorable pricing relative to a new issue of consolidated

obligations with similar features. The Bank did not assume any consolidated obligations from other FHLBanks during the six months ended June 30, 20202021 or 2019.2020.
Through March 30, 2019, the Bank was required, pursuant to guidance issued by the Finance Agency, to meet two daily liquidity standards, each of which assumed that the Bank was unable to access the market for consolidated obligations during a prescribed period. The first standard required the Bank to maintain sufficient funds to meet its obligations for 15 days under a scenario in which it was assumed that members did not renew any maturing, prepaid or called advances. The second standard required the Bank to maintain sufficient funds to meet its obligations for 5 days under a scenario in which it was assumed that members renewed all maturing and called advances, with certain exceptions for very large, highly rated members.
Beginning on March 31, 2019, the two liquidity standards discussed in the preceding paragraph were replaced by a single, more stringent requirement. On August 23, 2018, the Finance Agency issued an Advisory Bulletin and accompanying supervisory letter that, together, set forth the Finance Agency’s expectations with respect to the maintenance of sufficient liquidity to enable the FHLBanks to provide advances and fund letters of credit during a sustained capital markets disruption.disruption are set forth in an Advisory Bulletin and accompanying supervisory letter. More specifically, the Advisory Bulletin (hereinafter referred to as the “Liquidity AB”) sets forth the Finance Agency's expectations with respect to base case liquidity and funding gaps, among other things. The Liquidity AB sets forth ranges for the prescribed base case liquidity and funding gap measures and the supervisory letter identified the initial thresholds within those ranges that the Finance Agency believed were appropriate in light of then existing market conditions.
With respect to base case liquidity, the Bank is required to maintain a positive cash balance during a prescribed period of time ranging from 10 to 30 calendar days assuming no access to the market for consolidated obligations or other unsecured funding

sources and the renewal of all advances that are scheduled to mature during the measurement period. Initially, the Finance Agency indicated that it would consider a FHLBank to have adequate reserves of liquid assets if, from March 31, 2019 through December 30, 2019, it maintained 10 calendar days or more of positive daily cash balances and if, on and after December 31, 2019, it maintained 20 calendar days or more of positive daily cash balances. The supervisory letter sets forth the cash flow assumptions to be used by the FHLBanks which include, among other things, a reserve for potential draws on standby letters of credit and the inclusion of uncommitted/unencumbered U.S. Treasury securities with a remaining maturity no greater than 10 years which are classified as trading or available-for-sale securities as a cash inflow one business day after measurement. Effective March 31, 2019, the Liquidity AB rescinded the 5-day and 15-day liquidity standards discussed above.
Funding gaps measure the difference between a FHLBank’s assets and liabilities that are scheduled to mature during a specified period, expressed as a percentage of the FHLBank’s total assets. Depending on conditions in the financial markets, the Finance Agency believes (as stated in the Liquidity AB) that the FHLBanks should operate so as not to exceed a funding gap ratio between negative 10 percent and negative 20 percent for a three-month time horizon and between negative 25 percent and negative 35 percent for a one-year time horizon. These limits are designed to reduce the liquidity risks associated with a mismatch in a FHLBank’s asset and liability maturities, including an undue reliance on short-term debt funding, which may increase a FHLBank’s debt rollover risk. Initially, the Finance Agency indicated that it would consider a FHLBank to have adequate liquidity to address funding gap risks if, on and after December 31, 2018, the FHLBank maintained a funding gap ratio of negative 15 percent or better for the three-month time horizon and negative 30 percent or better for the one-year time horizon. For purposes of calculating the funding gap ratios, the FHLBanks may include estimates of expected cash inflows, including anticipated prepayments, for mortgage loans and mortgage-backed securities.MBS. In addition, uncommitted/unencumbered U.S. Treasury securities with a remaining maturity no greater than 10 years which are classified as trading securities are treated as maturing assets in the three-month time horizon regardless of maturity.
As a result of the deterioration in financial market conditions due to the COVID-19 outbreak, the Finance Agency temporarily revised its guidance with respect to base case liquidityOn and funding gaps. On March 3,after December 31, 2020, the Finance Agency indicated that the FHLBanks should maintain no less than 10 calendar days of positive daily cash balances through April 30, 2020 and that the FHLBanks should then return to 20 calendar days or more of positive daily cash balances by September 30, 2020. On March 12, 2020, the Finance Agency increased (through July 30, 2020) the funding gap ratios for the three-month and one-year time horizons to negative 25 percent or better and negative 40 percent or better, respectively. By September 30, 2020, the funding gap ratios for the three-month and one-year time horizons were not to exceed negative 20 percent and negative 35 percent, respectively. By December 31, 2020, the funding gap ratios were not to exceed the limits that were in place prior to the COVID-19 outbreak.
On May 26, 2020, the Finance Agency modified the guidance set forth in the immediately preceding paragraph. Pursuant to this most recent communication, the Finance Agency will considerconsiders a FHLBank to have adequate reserves of liquid assets if by August 31, 2020, it maintains 15 calendar days of positive daily cash balances and if, by December 31, 2020, itthe FHLBank maintains 20 calendar days of positive daily cash balances. Further, the Finance Agency will considerconsiders a FHLBank to have adequate liquidity to address funding gap risks if, byon and after December 31, 2020, itsthe FHLBank's funding gap ratios for the three-month and one-year time horizons do not exceed negative 20 percent and negative 35 percent, respectively.

The Bank was in compliance with the applicable base casethese liquidity requirements at all times during the six months ended June 30, 2020. During this same period, the Bank maintained its funding gap ratios within the limits initially established by the Finance Agency (i.e., 15 percent or better for the three-month time horizon and 30 percent or better for the one-year time horizon).2021.
The Bank’s access to the capital markets has never been interrupted to an extent that the Bank’s ability to meet its obligations was compromised and the Bank does not currently believe that its ability to issue consolidated obligations will be impeded to that extent in the future. If, however, the Bank were unable to issue consolidated obligations for an extended period of time, the Bank would eventually exhaust the availability of purchased federal funds (including borrowings from other FHLBanks) and repurchase agreements as sources of funds. It is also possible that an event (such as a natural disaster or a pandemic like COVID-19) that might impede the Bank’s ability to raise funds by issuing consolidated obligations would also limit the Bank’s ability to access the markets for federal funds purchased and/or repurchase agreements.
Under those circumstances, to the extent that the balance of principal and interest that came due on the Bank’s debt obligations and the funds needed to pay its operating expenses exceeded the cash inflows from its interest-earning assets and proceeds from maturing assets, and if access to the market for consolidated obligations was not again available, the Bank would seek to access funding under the Contingency Agreement to repay any principal and interest due on its consolidated obligations. However, if the Bank were unable to raise funds by issuing consolidated obligations, it is likely that the other FHLBanks would have similar difficulties issuing debt. If funds were not available under the Contingency Agreement, the Bank’s ability to conduct its operations would be compromised even earlier than if this funding source was available.
A summary of the Bank’s contractual cash obligations and off-balance-sheet lending-related financial commitments by due date or remaining maturity as of December 31, 20192020 is provided in the 20192020 10-K.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
The following quantitative and qualitative disclosures about market risk should be read in conjunction with the quantitative and qualitative disclosures about market risk that are included in the 20192020 10-K. The information provided in this item is intended to update the disclosures made in the 20192020 10-K.
As a financial intermediary, the Bank is subject to interest rate risk. Changes in the level of interest rates, the slope of the interest rate yield curve, and/or the relationships (or spreads) between interest yields for different instruments have an impact on the Bank’s estimated market value of equity and its earnings. This risk arises from a variety of instruments that the Bank enters into on a regular basis in the normal course of its business.
The terms of member advances, investment securities, and consolidated obligations may present interest rate risk and/or embedded option risk. As discussed in Management’s Discussion and Analysis of Financial Condition and Results of

Operations, the Bank makes extensive use of interest rate derivative instruments, primarily interest rate swaps, swaptions and caps, to manage the risk arising from these sources.
The Bank has investments in residential mortgage-related assets, primarily CMOs and MPF mortgage loans, both of which present prepayment risk. This risk arises from the mortgagors’ option to prepay their mortgages, making the effective maturities of these mortgage-based assets relatively more sensitive to changes in interest rates and other factors that affect the mortgagors’ decisions to repay their mortgages as compared to other long-term investment securities that do not have prepayment features. A decline in interest rates generally accelerates mortgage refinancing activity, thus increasing prepayments and thereby shortening the effective maturity of the mortgage-related assets. Conversely, rising rates generally slow prepayment activity and lengthen a mortgage-related asset’s effective maturity.
The Bank has managed the potential prepayment risk embedded in mortgage assets by purchasing securities that maintain their original principal balance for a fixed number of years, by purchasing highly structured tranches of mortgage securities that substantially limit the effects of prepayment risk, by issuing a combination of callable and non-callable debt with varying maturities, and/or by using interest rate derivative instruments to offset prepayment risk specific both to particular securities and to the overall mortgage portfolio.
The Bank’s Enterprise Market Risk Management Policy provides a risk management framework for the financial management of the Bank consistent with the strategic principles outlined in its Strategic Business Plan. The Bank develops its funding and

hedging strategies to manage its interest rate risk within the risk limits established in its Enterprise Market Risk Management Policy.
The Enterprise Market Risk Management Policy articulates the Bank’s tolerance for the amount of overall interest rate risk the Bank will assume by limiting the maximum estimated loss in market value of equity that the Bank would incur under simulated 200 basis point changes in interest rates to 15 percent of the estimated base case market value. As reflected in the table below entitled "Market Value of Equity," the Bank was in compliance with this limit at June 30, 2020,2021, March 31, 20202021 and December 31, 2019.2020.
As part of its ongoing risk management process, the Bank calculates an estimated market value of equity for a base case interest rate scenario and for interest rate scenarios that reflect parallel interest rate shocks. The base case market value of equity is calculated by determining the estimated fair value of each instrument on the Bank’s balance sheet, and subtracting the estimated aggregate fair value of the Bank’s liabilities from the estimated aggregate fair value of the Bank’s assets. For purposes of these calculations, mandatorily redeemable capital stock is treated as equity rather than as a liability. The fair values of the Bank’s financial instruments (both assets and liabilities) are determined using either vendor prices or a pricing model. For those instruments for which a pricing model is used, the calculations are based upon parameters derived from market conditions existing at the time of measurement, and are generally determined by discounting estimated future cash flows at the replacement (or similar) rate for new instruments of the same type with the same or very similar characteristics. The market value of equity calculations include non-financial assets and liabilities, such as premises and equipment, other assets, payables for AHP, and other liabilities at their recorded carrying amounts.
For purposes of compliance with the Bank’s Enterprise Market Risk Management Policy limit on estimated losses in market value, market value of equity losses are defined as the estimated net sensitivity of the value of the Bank’s equity (the net value of its portfolio of assets, liabilities and interest rate derivatives) to 200 basis point parallel shifts in interest rates.

The market value of equity figures reflected in the table above were derived in accordance with Finance Agency guidance. The Bank has on its balance sheet long-term, fixed-rate, putable advances that can be terminated by the Bank on specified future dates pursuant to a put option purchased from the member. These advances are hedged with interest rate swaps where the Bank pays a fixed-rate coupon and receives a variable-rate coupon, and sells a call option to the swap counterparty pursuant to which that counterparty can cancel the swap on specified future dates. The call/put option dates mirror each other throughout the life of the instruments. Given the different discount curves that are used to value the putable advances and the associated cancelable interest rate swaps, the modeled results can produce an outcome where the advance and the corresponding interest rate swap are not terminated on the same date. InTypically, in practice, if the swap counterparty calls the interest rate swap, the Bank concurrently puts the advance. After

A related measure of interest rate risk is duration of equity. Duration is the weighted average maturity (typically measured in months or years) of an instrument’s cash flows, weighted by the present value of those cash flows. As such, duration provides an estimate of an instrument’s sensitivity to small changes in market interest rates. The duration of assets is generally expressed as a positive figure, while the duration of liabilities is generally expressed as a negative number. The change in value of a specific instrument for given changes in interest rates will generally vary in inverse proportion to the instrument’s duration. As
75

Table of Contents```
market interest rates decline, instruments with a positive duration are expected to increase in value, while instruments with a negative duration are expected to decrease in value. Conversely, as interest rates rise, instruments with a positive duration are expected to decline in value, while instruments with a negative duration are expected to increase in value.
74

Table of Contents
The values of instruments having relatively longer (or higher) durations are more sensitive to a given interest rate movement than instruments having shorter durations; that is, risk increases as the absolute value of duration lengthens. For instance, the value of an instrument with a duration of three years will theoretically change by three percent for every one percentage point (100 basis point) change in interest rates, while the value of an instrument with a duration of five years will theoretically change by five percent for every one percentage point change in interest rates.
The duration of individual instruments may be easily combined to determine the duration of a portfolio of assets or liabilities by calculating a weighted average duration of the instruments in the portfolio. These combinations provide a single straightforward metric that describes the portfolio’s sensitivity to interest rate movements. These additive properties can be applied to the assets and liabilities on the Bank’s balance sheet. The difference between the combined durations of the Bank’s assets and the combined durations of its liabilities is sometimes referred to as duration gap and provides a measure of the relative interest rate sensitivities of the Bank’s assets and liabilities.
Duration gap is a useful measure of interest rate sensitivity but does not account for the effect of leverage, or the effect of the absolute duration of the Bank’s assets and liabilities, on the sensitivity of its estimated market value of equity to changes in interest rates. The inclusion of these factors results in a measure of the sensitivity of the value of the Bank’s equity to changes in market interest rates referred to as the duration of equity. Duration of equity is the market value weighted duration of assets minus the market value weighted duration of liabilities divided by the market value of equity.
The significance of an entity’s duration of equity is that it can be used to describe the sensitivity of the entity’s market value of equity to movements in interest rates. A duration of equity equal to zero would mean, within a narrow range of interest rate movements, that the Bank had neutralized the impact of changes in interest rates on the market value of its equity.
A positive duration of equity would mean, within a narrow range of interest rate movements, that for each one year of duration the estimated market value of the Bank’s equity would be expected to decline by about 0.01 percent for every positive 0.01 percent change in the level of interest rates. A positive duration generally indicates that the value of the Bank’s assets is more sensitive to changes in interest rates than the value of its liabilities (i.e., that the duration of its assets is greater than the duration of its liabilities).
Conversely, a negative duration of equity would mean, within a narrow range of interest rate movements, that for each one year of negative duration the estimated market value of the Bank’s equity would be expected to increase by about 0.01 percent for every positive 0.01 percent change in the level of interest rates. A negative duration generally indicates that the value of the Bank’s liabilities is more sensitive to changes in interest rates than the value of its assets (i.e., that the duration of its liabilities is greater than the duration of its assets).
