Note 1 — Basis of Presentation
The information about the Federal Home Loan Bank of San Francisco (Bank) included in these unaudited financial statements reflects all adjustments that, in the opinion of the Bank, are necessary for a fair statement of results for the periods presented. These adjustments are of a recurring nature, unless otherwise disclosed. The results of operations in these interim statements are not necessarily indicative of the results to be expected for any subsequent period or for the entire year ending December 31, 2021. These unaudited financial statements should be read in conjunction with the Bank’s Annual Report on Form 10-K for the year ended December 31, 2020 (2020 Form  10-K).
There have been no changes to the basis of presentation of the Bank’s financial instruments meeting netting requirements or of the Bank’s investments in variable interest entities disclosed in “Item 8. Financial Statements and Supplementary Data – Note 1 – Summary of Significant Accounting Policies” in the Bank’s 2020 Form 10-K.
Use of Estimates. The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP) requires management to make a number of judgments, estimates, and assumptions that may affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities, and the reported amounts of income, expenses, gains, and losses during the reporting period. The most significant of these estimates include:

estimating fair values of investments classified as trading and available-for-sale (AFS), derivatives and associated hedged items carried at fair value in accordance with the accounting for derivative instruments and associated hedging activities, and financial instruments carried at fair value under the fair value option; and

Note 2 — Recently Issued Accounting Guidance
The following table provides a summary of recently issued accounting standards that may have an effect on the financial statements.
Accounting Standards Update (ASU)DescriptionEffective DateEffect on the Financial Statements or Other Significant Matters
Facilitation of the Effects of Reference Rate Reform on Financial Reporting, as amended (ASU 2020-04)This guidance provides temporary optional guidance to ease the potential burden in accounting for reference rate reform. The new guidance provides optional expedients and exceptions for applying generally accepted accounting principles to transactions affected by reference rate reform if certain criteria are met. These transactions include:
• contract modifications,
• hedging relationships, and
• sale or transfer of debt securities classified as HTM.held-to-maturity (HTM).
This guidance is effective immediately for the Bank, and the Bank may elect to apply the amendments prospectively through December 31, 2022.The Bank has assessed the guidance and plans to elect some of the optional expedients and exceptions provided; however, the full effect on the Bank’s financial condition, results of operations, and cash flows has not yet been determined. In particular, during the fourth quarter of 2020, the Bank elected optional expedients specific to the discounting transition on a retrospective basis, which did not have a material effect.
Note 3 — Investments
The Bank makes short-term investments in interest-bearing deposits, securities purchased under agreements to resell, and Federal funds sold, and may make other investments in debt securities, which are classified as trading, AFS, or held-to-maturity (HTM).HTM.
Interest-Bearing Deposits, Securities Purchased under Agreements to Resell, and Federal Funds Sold. The Bank invests in interest-bearing deposits, securities purchased under agreements to resell, and Federal funds sold to provide short-term liquidity. These investments are generally transacted with counterparties that have received an investment grade credit rating of BBB or greater by a nationally recognized statistical rating organization (NRSRO). At March 31,June 30, 2021, and December 31, 2020, NaN of these investments were with counterparties rated below BBB nor with unrated counterparties. These may differ from any internal ratings of the investments by the Bank, if applicable.
Federal funds sold are unsecured loans that are generally transacted on an overnight term. Federal Housing Finance Agency (Finance Agency) regulations include a limit on the amount of unsecured credit the Bank may extend to a counterparty. At March 31,June 30, 2021, and December 31, 2020, all investments in interest-bearing deposits and Federal funds sold were repaid or expected to be repaid according to the relevant contractual terms. NoNaN allowance for credit losses was recorded for these assets at March 31,June 30, 2021, and December 31, 2020. Carrying values of interest-bearing deposits and Federal funds sold exclude de minimis amounts of accrued interest receivable as of March 31,June 30, 2021, and December 31, 2020.
Based upon the collateral held as security and collateral maintenance provisions with its counterparties, the Bank determined that no0 allowance for credit losses was needed for its securities purchased under agreements to resell at March 31,June 30, 2021, and December 31, 2020. The carrying value of securities purchased under agreements excludes de minimis amounts of accrued interest receivable as of March 31,June 30, 2021, and December 31, 2020.

To evaluate investment securities for credit loss at March 31,June 30, 2021, the Bank employed the following methodologies, based on the type of security.
AFS and HTM Securities (Excluding PLRMBS) – The Bank’s AFS and HTM securities are principally U.S. obligations and MBS issued by Ginnie Mae, Freddie Mac, and Fannie Mae that are backed by single-family or multifamily mortgage loans. The Bank only purchases securities considered investment quality. Excluding PLRMBS investments, at March 31,June 30, 2021, and December 31, 2020, approximately 100% of AFS securities and HTM securities, based on amortized cost, were rated A, or above, by an NRSRO, based on the lowest long-term credit rating for each security. These may differ from any internal ratings of the securities by the Bank, if applicable.
At March 31,June 30, 2021, and December 31, 2020, certain of the Bank’s AFS securities were in an unrealized loss position. These losses are considered temporary as the Bank expects to recover the entire amortized cost basis on these AFS investment securities and neither intends to sell these securities nor considers it more likely than not that it will be required to sell these securities before its anticipated recovery of each security's remaining amortized cost basis. Further, the Bank has not experienced any payment defaults on the instruments. In addition, substantially all of these securities carry an implicit or explicit government guarantee. As a result, no0 allowance for credit losses was recorded on these AFS securities at March 31,June 30, 2021, and December 31, 2020.
As of March 31,June 30, 2021, and December 31, 2020, the Bank had not established an allowance for credit loss on any of its HTM securities because the securities: (i) were all highly rated or had short remaining terms to maturity, (ii) had not experienced, nor did the Bank expect, any payment default on the instruments, and (iii) in the case of GSE or other U.S. obligations, carry an implicit or explicit government guarantee such that the Bank considers the risk of nonpayment to be zero.

Private-Label Residential Mortgage-Backed Securities – The Bank also holds investments in PLRMBS. The Bank has not purchased any PLRMBS since the first quarter of 2008. However, many of these securities have subsequently experienced significant credit deterioration. As of March 31,June 30, 2021, and December 31, 2020, approximately 6% of PLRMBS (AFS and HTM combined, based on amortized cost) were rated A, or above, by an NRSRO; and the remaining securities were either rated less than A, or were unrated. To determine whether an allowance for credit loss is necessary on these securities, the Bank uses cash flow analyses. For certain PLRMBS where underlying collateral data is not available, alternative procedures as determined by the Bank are used to assess these securities for credit loss measurement.
At each quarter end, the Bank compares the present value of the cash flows expected to be collected on its PLRMBS, using the effective interest rate, to the amortized cost basis of the securities to determine whether a credit loss exists. The expected credit losses are measured using:
expected housing price changes;
expected interest rate assumptions;
the remaining payment terms for the security;
expected default rates based on underlying loan-level borrower and loan characteristics;
loss severities on the collateral supporting each unique PLRMBS based on underlying loan-level borrower and loan characteristics; and
prepayment speeds based on underlying loan-level borrower and loan characteristics.
The projected cash flows are based on a number of assumptions and expectations, and the results of these models can vary significantly with changes in these assumptions and expectations. The cash flows determined reflects management’s expectations and includes a base case housing price forecast for near- and long-term horizons.
For all the PLRMBS in its AFS and HTM portfolios, the Bank does not intend to sell any security and it is not more likely than not that the Bank will be required to sell any security before its anticipated recovery of the remaining amortized cost basis.
For securities with an OTTI recognized pursuant to the impairment guidance in effect prior to January 1, 2020, as of March 31,June 30, 2021 (securities for which the Bank determined that it does not expect to recover the entire amortized cost basis), the following table presents a summary of the significant inputs used in measuring the fair value of PLRMBS classified as Level 3 as of March 31,June 30, 2021, and the related current credit enhancement for the Bank.

Credit enhancement is defined as the percentage of subordinated tranches, excess spread, and over-collateralization, if any, in a security structure that will generally absorb losses before the Bank will experience a loss on the security. The calculated averages represent the dollar-weighted averages of all the PLRMBS investments in each category shown. The classification is based on the model used to run the estimated cash flows for the CUSIP, which may not necessarily be the same as the classification at the time of origination.
The total net accretion recognized in interest income associated with PLRMBS that were other-than-temporarily impaired prior to January 1, 2020, totaled $17$16 and $20$17 for the three months ended March 31,June 30, 2021 and 2020, respectively, and $33 and $37 for the six months ended June 30, 2021 and 2020, respectively.

In general, the Bank elects to transfer any PLRMBS that incurred a credit loss during the applicable period from the Bank’s HTM portfolio to its AFS portfolio at their fair values. The Bank recognized a credit loss on these HTM PLRMBS, which the Bank believes is evidence of a significant decline in the credit quality of the underlying collateral. The decline in the credit quality of the underlying collateral is the basis for the transfers to the AFS portfolio. These transfers allow the Bank the option to sell these securities prior to maturity in view of changes in interest rates, changes in prepayment risk, or other factors, while recognizing the Bank’s intent to hold these securities for an indefinite period of time. The Bank did not0t transfer any PLRMBS from its HTM portfolio to its AFS portfolio during the three and six months ended March 31, 2021.June 30, 2021, 0r during the three months ended June 30, 2020. The Bank transferred PLRMBS from its HTM portfolio to its AFS portfolio with an amortized cost and fair value of $1 during the threesix months ended March 31,June 30, 2020.
For the Bank’s PLRMBS, the Bank recorded a reversal of credit losses of $5$1 and $6 during the three and six months ended March 31,June 30, 2021, respectively, primarily resulting from lower default rates as well as improved projected credit performance in part related to a more optimistic economic outlook because of the monetary and fiscal stimulus measures taken by the U.S. government. The Bank recorded a provision for credit losses on its PLRMBS portfolio of $39 during the three months ended March 31, 2020. The Bank experienced declines in fair value in March 2020 as a result of disruptions in the financial markets combined with illiquidity in the PLRMBS market and decreased expectations of the performance of loan collateral underlying these securities, which caused these assets to be valued at discounts to their amortized cost. The Bank recorded a provision for credit losses on its PLRMBS portfolio of $30 during the six months ended June 30, 2020. As a result of improvement in the Bank’s PLRMBS fair values during the three months ended June 30, 2020, the Bank recorded a reversal of credit losses on its PLRMBS portfolio of $9.

Many of the Bank’s advances are prepayable at the borrower’s option. However, when advances are prepaid, the borrower is generally charged a prepayment fee intended to make the Bank financially indifferent to the prepayment. In addition, for certain advances with full or partial prepayment symmetry, the Bank may charge the borrower a prepayment fee or pay the borrower a prepayment credit depending on certain circumstances, such as movements in interest rates, when the advance is prepaid. The Bank had advances with full prepayment symmetry outstanding totaling $18,638$15,443 at March 31,June 30, 2021, and $19,919 at December 31, 2020. The Bank had advances with partial prepayment symmetry outstanding totaling $1,635$1,617 at March 31,June 30, 2021, and $1,817 at December 31, 2020. Some advances may be repaid on pertinent call dates without prepayment fees (callable advances). The Bank had callable advances outstanding totaling $650$70 at March 31,June 30, 2021, and $1,100 at December 31, 2020.
The Bank had putable advances totaling $220 at March 31,June 30, 2021, and December 31, 2020. At the Bank’s discretion, the Bank may terminate these advances on predetermined exercise dates and offer replacement funding at prevailing market rates, subject to certain conditions. The Bank would typically exercise such termination rights when interest rates increase relative to contractual rates.
The following table summarizes advances at March 31,June 30, 2021, and December 31, 2020, by the earlier of the year of redemption term or next call date for callable advances and by the earlier of the year of redemption term or next put date for putable advances.

(1)    Interest income amounts exclude the interest effect of interest rate exchange agreements with derivative counterparties; as a result, the total interest income amounts will not agree to the Statements of Income. The amount of interest income from advances can vary depending on the amount outstanding, terms to maturity, interest rates, and repricing characteristics.
(2)    Nonmember institution.
The Bank held a security interest in collateral from each of the top five advances borrowers and their affiliates sufficient to support their respective advances outstanding, and the Bank does not expect to incur any credit losses on these advances.
Credit Risk Exposure and Security Terms. The Bank manages its credit exposure related to advances through an integrated approach that generally provides for a credit limit to be established for each borrower, includes an ongoing review of each borrower’s financial condition, and is coupled with conservative collateral and lending policies to limit the risk of loss while taking into account borrowers’ needs for a reliable funding source.
In addition, the Bank lends to member financial institutions that have a principal place of business in Arizona, California, or Nevada, in accordance with federal law and Finance Agency regulations. Specifically, the Bank is required to obtain sufficient collateral to fully secure credit products up to the member’s total credit limit. Borrowers may pledge the following eligible assets to secure advances:
one-to-four-family first lien residential mortgage loans;
securities issued, insured, or guaranteed by the U.S. government or any of its agencies, including without limitation MBS backed by Fannie Mae, Freddie Mac, or Ginnie Mae;
cash or deposits in the Bank;
certain other real estate-related collateral, such as multifamily loans, commercial real estate loans, and second lien residential mortgage loans or home equity loans; and

small business, small farm, and small agribusiness loans that are fully secured by collateral (such as real estate, equipment and vehicles, accounts receivable, and inventory) from members that are community financial institutions.

At March 31,June 30, 2021, and December 31, 2020, none of the Bank’s credit products were past due or on nonaccrual status. There were no troubled debt restructurings related to credit products during the threesix months ended March 31,June 30, 2021, or during 2020.
Based on the collateral pledged as security for advances, the Bank’s credit analyses of borrowers’ financial condition, repayment history on advances, and the Bank’s credit extension and collateral policies as of March 31,

The Bank did not have any advances with embedded features that met the requirements to separate the embedded feature from the host contract and designate the embedded feature as a stand-alone derivative at March 31,June 30, 2021, or December 31, 2020. The Bank has generally elected to account for certain advances with embedded features under the fair value option, and these advances are carried at fair value on the Statements of Condition. For more information, see Note 11 – Derivatives and Hedging Activities and Note 12 – Fair Value.
Prepayment Fees, Net. The Bank charges borrowers prepayment fees or pays borrowers prepayment credits when the principal on certain advances is paid prior to original maturity.

Relief to Borrowers During the COVID-19 Pandemic. Starting in the second quarter of 2020, the Bank elected to apply the troubled debt restructuring (TDR) relief provisions provided by the Coronavirus Aid, Relief, and Economic Security Act (CARES Act). As such, all loan modifications granted to borrowers adversely affected by the COVID-19 pandemic (COVID-related modifications) meeting the provisions of the CARES Act are excluded from TDR classification and accounting, and the Bank considers these loans to have a current payment status as long as payments are being made in accordance with the new terms. At March 31,June 30, 2021, the Bank had $16$31 in these modifications outstanding, of which $1 were on nonaccrual status. At December 31, 2020, the Bank had a de minimis amount in these modifications outstanding. Alternatively, COVID-related modifications that do not meet the provisions of the CARES Act continue to be assessed for TDR classification.
Participating members may grant a forbearance period to borrowers who have requested forbearance based on COVID-19 related difficulties regardless of the status of the loan at the time of the request. The accrual status for loans under forbearance will be driven by the past due status of the loan. For more information related to the Bank’s accounting policies for the CARES Act, see “Item 8. Financial Statements and Supplementary Data – Note 1 – Summary of Significant Accounting Policies” in the Bank’s 2020 Form 10-K.
Payment Status of Mortgage Loans. Payment status is the key credit quality indicator for conventional mortgage loans and allows the Bank to monitor the migration of past due loans. Past due loans are those where the borrower has failed to make timely payments of principal and/orand interest in accordance with the terms of the loan. Other delinquency statistics include nonaccrual loans and loans in process of foreclosure. The following tables present the payment status for mortgage loans and other delinquency statistics for Bank’s mortgage loans at March 31,June 30, 2021, and December 31, 2020.

(1)    The amortized cost in a loan is the unpaid principal balance of the loan, adjusted for net deferred loan fees or costs, unamortized premiums or discounts, and direct write-downs.
(2)    At March 31,June 30, 2021, unpaid principal balances of conventional mortgage loans held for portfolio that were in a forbearance plan as a result of the COVID-19 pandemic totaled $66.$50. Of that total, $8$3 were current, $2$3 were 30 to 59 days past due, $3 were 60 to 89 days past due, and $53$41 were greater than 89 days past due and in nonaccrual payment status. At December 31, 2020, unpaid principal balances of conventional mortgage loans held for portfolio that were in a forbearance plan as a result of the COVID-19 pandemic totaled $78. Of that total, $2 were current, $7 were 30 to 59 days past due, $1 were 60 to 89 days past due, and $68 were greater than 89 days past due and in nonaccrual payment status. The conventional mortgage loans in forbearance represent 4% of the Bank’s mortgage loans held for portfolio at March 31,June 30, 2021, and December 31, 2020.
(3)    Includes loans for which the servicer has reported a decision to foreclose or to pursue a similar alternative, such as deed-in-lieu. Loans in process of foreclosure are included in past due or current loans depending on their delinquency status.
(4)    At March 31,June 30, 2021, and December 31, 2020, $77$52 and $103, respectively, of these mortgage loans on nonaccrual status did not have an associated allowance for credit losses.
(5)    Represents loans that are 90 days or more past due or in the process of foreclosure as a percentage of the recorded investment of total mortgage loans outstanding.
(6)    The amortized costs of the mortgage loans by origination year in the 2016 to 2020 column and prior to 2016 column that were previously disclosed in the “Mortgage Loans Held for Portfolio” note were incorrectly presented as of December 31, 2020, in the Bank’s 2020 Form 10-K. The amortized costs of the mortgage loans by origination year as of December 31, 2020, have been corrected. The total amortized costs presented for each period were properly disclosed. These revisions had no effect on the Bank’s total assets, net interest income, or net income for all affected periods.
Allowance for Credit Losses on Mortgage Partnership Finance® (MPF®) Loans. MPF loans are evaluated collectively for expected credit losses when similar risk characteristics exist. MPF loans that do not share risk characteristics with other pools are evaluated for expected credit losses on an individual basis, factoring in the credit enhancement structure at the master commitment level. The Bank determines its allowances for credit losses on MPF loans through analyses that include consideration of various loan portfolio and collateral related characteristics, such as past performance, current conditions, and reasonable and supportable forecasts of expected economic conditions. (“Mortgage Partnership Finance” and “MPF” are registered trademarks of the FHLBank of Chicago.) The Bank uses models that employ a variety of methods, such as projected cash flows, to estimate
20

expected credit losses over the life of the loans. These models rely on a number of inputs, such as current and forecasted property values and interest rates as well as historical borrower behavior experience. At March 31,June 30, 2021, the Bank’s reasonable and supportable forecast of housing prices expects, on average, for prices to appreciate 3.9%

6.1% over a one-year forecast horizon before reverting to long-term housing price appreciation rates of 3.6%3.0% after five additional years in the forecast based on historical averages. At December 31, 2020, the Bank’s reasonable and supportable forecast of housing prices expects, on average, for prices to appreciate 2.3% over a one-year forecast horizon before reverting to long-term housing price appreciation rates of 3.8% over a three-year forecast horizon based on historical averages. The Bank also incorporates associated credit enhancements, if any, to determine its estimate of expected credit losses.
Certain MPF loans may be evaluated for credit losses by the Bank using the practical expedient for collateral-dependent assets. A mortgage loan is considered collateral-dependent if repayment is expected to be provided by the sale of the underlying property, that is, if it is considered likely that the borrower will default. The Bank may estimate the fair value of this collateral by applying an appropriate loss severity rate or using third-party estimates or property valuation models. The expected credit loss of a collateral-dependent mortgage loan is equal to the difference between the amortized cost of the loan and the estimated fair value of the collateral, less estimated selling costs. The Bank will either reserve for these estimated losses or record a direct charge-off of the loan balance, if certain triggering criteria are met. Expected recoveries of prior charge-offs, if any, are included in the allowance for credit loss.
The following table presents a rollforward of the allowance for credit losses on the mortgage loan portfolio for the three and six months ended March 31,June 30, 2021 and 2020. The amount of charge-offs and recoveries of allowance for credit losses on the mortgage loan portfolio were de minimis for the three and six months ended March 31,June 30, 2021 and 2020.

Note 6 — Deposits
The Bank maintains demand deposit accounts that are directly related to the extension of credit to members and offers short-term deposit programs to members and qualifying nonmembers. In addition, a member that services mortgage loans may deposit in the Bank funds collected in connection with the mortgage loans, pending disbursement of these funds to the owners of the mortgage loans. The Bank classifies these types of deposits as non-interest-bearing deposits. Deposits classified as demand, overnight, and other pay interest based on a daily interest rate. Term deposits pay interest based on a fixed rate determined at the issuance of the deposit.

Note 7 — Consolidated Obligations
Consolidated obligations, consisting of consolidated obligation bonds and discount notes, are jointly issued by the Federal Home Loan Banks (FHLBanks) through the Office of Finance, which serves as the FHLBanks’ agent. As provided by the Federal Home Loan Bank Act of 1932, as amended (FHLBank Act) or by regulations governing the operations of the FHLBanks, all FHLBanks have joint and several liability for all FHLBank consolidated obligations. For a discussion of the joint and several liability regulation, see “Item 8. Financial Statements and Supplementary Data – Note 16 – Commitments and Contingencies” in the Bank’s 2020 Form 10-K. In connection with each issuance of consolidated obligations, each FHLBank specifies the type, term, and amount of debt it requests to have issued on its behalf. The Office of Finance tracks the amount of debt issued on behalf of each FHLBank. In addition, the Bank separately tracks and records as a liability its specific portion of the consolidated obligations issued and is the primary obligor for that portion of the consolidated obligations issued. The Finance Agency and the U.S. Secretary of the Treasury have oversight over the issuance of FHLBank debt through the Office of Finance.
Redemption Terms. The following is a summary of the Bank’s participation in consolidated obligation bonds at March 31,June 30, 2021, and December 31, 2020.

Note 9 — Capital
Capital Requirements. Under the Housing and Economic Recovery Act of 2008, the Director of the Finance Agency is responsible for setting the risk-based capital standards for the FHLBanks. The FHLBank Act and regulations governing the operations of the FHLBanks require that the Bank’s minimum capital stock requirement for shareholders must be sufficient to enable the Bank to meet its regulatory requirements for total capital, leverage capital, and risk-based capital. The Bank must maintain: (i) total regulatory capital in an amount equal to at least 4%
24

Table of Contents
Federal Home Loan Bank of San Francisco
Notes to Financial Statements (continued)


of its total assets, (ii) leverage capital in an amount equal to at least 5% of its total assets, and (iii) permanent capital in an amount that is greater than or equal to its risk-based capital requirement.
The Finance Agency requires each FHLBank to maintain a ratio of at least two percent2% of capital stock to total assets in order to help preserve the cooperative structure incentives that encourage members to remain fully engaged in the oversight of their investment in the FHLBank. The Finance Agency will consider the proportion of capital stock to assets, measured on a daily average basis at monthend, when assessing each FHLBank’s capital management practices. As of March 31,June 30, 2021, and December 31, 2020, the Bank complied with this capital guidance.
Because the Bank issues only Class B stock, regulatory capital and permanent capital for the Bank are both composed of retained earnings and Class B stock, including mandatorily redeemable capital stock (which is classified as a liability for financial reporting purposes). Regulatory capital and permanent capital do not include AOCI. Leverage capital is defined as the sum of permanent capital, weighted by a 1.5 multiplier, plus non-permanent capital.
The risk-based capital requirement is equal to the sum of the Bank’s credit risk, market risk, and operations risk capital requirements, all of which are calculated in accordance with the rules and regulations of the Finance Agency. The Finance Agency may require an FHLBank to maintain a greater amount of permanent capital than is required by the risk-based capital requirement as defined.

Excess Stock Repurchase, Retained Earnings, and Dividend Framework. By Finance Agency regulation, dividends may be paid only out of current net earnings or previously retained earnings. As required by the Finance Agency, the Bank’s Excess Stock Repurchase, Retained Earnings, and Dividend Framework (Framework) summarizes the Bank’s capital management principles and objectives, as well as its policies and practices, with respect to retained earnings, dividend payments, and the repurchase of excess capital stock. The Bank may be restricted from paying dividends if the Bank is not in compliance with any of its minimum capital requirements or if payment would cause the Bank to fail to meet any of its minimum capital requirements. In addition, the Bank may not pay dividends if any principal or interest due on any consolidated obligations has not been paid in full or is not expected to be paid in full, or, under certain circumstances, if the Bank fails to satisfy certain liquidity requirements under applicable Finance Agency regulations.
26

Table of Contents
Federal Home Loan Bank of San Francisco
Notes to Financial Statements (continued)


The Bank’s board of directors reviews the Framework at least annually and may amend the Framework from time to time. The Framework includes a dividend philosophy to endeavor to pay a quarterly dividend at an annualized rate between 5% and 7%. The decision to declare any dividend and the dividend rate are at the discretion of the Bank’s board of directors, which may choose to follow the dividend philosophy as guidance in the dividend declaration. The Board may also revise or eliminate the dividend policy in the future. The Bank’s historical dividend rates and the dividend philosophy are not indicative of future dividend declarations.
The Bank’s Risk Management Policy limits the payment of dividends if the ratio of the Bank’s estimated market value of total capital to par value of capital stock falls below certain levels. If this ratio at the end of any quarter is less than 100% but greater than or equal to 70%, any dividend would be limited to an annualized rate no greater than the daily average of the Federal funds effective rate for the applicable quarter (subject to certain conditions), and if this ratio is less than 70%, the Bank would be restricted from paying a dividend. The ratio of the Bank’s estimated market value of total capital to par value of capital stock was 295%293% as of March 31,June 30, 2021.
In addition, the Bank monitors the condition of its balance sheet, its financial performance, its capital position, overall financial market conditions, and other relevant information as the basis for determining the payment of dividends in future quarters.
Retained Earnings – The Bank’s Framework assesses the level and adequacy of retained earnings and establishes amounts to be retained in restricted retained earnings, which are not made available in the current dividend period, and maintains an amount of total retained earnings at least equal to its required retained earnings as described in the Framework. As determined using the Bank’s methodology, the required level of total retained earnings had ranged from $2,400 to $2,500 during 2019 and continuing through September 2020. In September 2020, the methodology was revised and resulted in a required level of retained earnings of $2,900. In January 2021, the methodology was further revised and resulted in a required level of retained earnings of $1,900. In July 2021, the methodology was further revised and resulted in a required level of retained earnings of $1,500. The Bank satisfies its retained earnings requirement with both restricted retained earnings (i.e., amounts related to the Joint Capital Enhancement (JCE) Agreement) and unrestricted retained earnings. The Bank’s retained earnings requirement may be changed at any time. The board of directors periodically reviews the retained earnings methodology and analysis to determine whether any adjustments are appropriate.
The JCE Agreement is intended to enhance the capital position of each FHLBank. In accordance with the JCE Agreement, each FHLBank is required to allocate 20% of its net income each quarter to a separate restricted retained earnings account until the balance of the account, calculated as of the last day of each calendar quarter, equals at least 1% of that FHLBank's average balance of outstanding consolidated obligations for the calendar quarter. Under the JCE Agreement, these restricted retained earnings will not be available to pay dividends. With the decline in consolidated obligations outstanding in 2020, the Bank ceased contributions to restricted retained earnings in the fourth quarter of 2020, in accordance with the JCE Agreement, and no further allocations of net income into restricted retained earnings are required until such time as the allocation requirement exceeds the balance of restricted retained earnings. Additionally, the JCE Agreement provides that amounts in restricted retained earnings in excess of 150% of the Bank’s restricted retained earnings minimum (i.e., 1% of the Bank’s total consolidated obligations calculated as of the last day of each calendar quarter) may be released from restricted retained earnings. As of June 30, 2021, the amount in restricted retained earnings was 152% of the Bank’s restricted retained earnings minimum. The Bank’s restricted retained earnings totaled $761 at March 31,June 30, 2021, and December 31, 2020. The Bank’s unrestricted retained earnings totaled $2,983$3,004 and $2,919 at March 31,June 30, 2021, and December 31, 2020, respectively.

anticipated earnings. There is no requirement that the board of directors declare and pay any dividend. A decision by the board of directors to declare or not declare a dividend is a discretionary matter and is subject to the requirements and restrictions of the FHLBank Act and applicable requirements under the regulations governing the operations of the FHLBanks.
In addition, Finance Agency rules do not permit the Bank to pay dividends in the form of capital stock if its excess capital stock exceeds 1% of its total assets. Excess capital stock is defined as the aggregate of the capital stock held by each shareholder in excess of its minimum capital stock requirement, as established by the Bank’s capital plan. Excess capital stock totaled $161,$149, or 0.28% of total assets as of March 31,June 30, 2021. Excess capital stock totaled $161, or 0.23% of total assets as of December 31, 2020.
In the firstsecond quarter of 2021, the Bank paid dividends at an annualized rate of 6.00%, totaling $34, including $34 in dividends on capital stock and a de minimis amount in dividends on mandatorily redeemable capital stock. In the second quarter of 2020, the Bank paid dividends at an annualized rate of 5.00%, totaling $30,$40, including $30$38 in dividends on capital stock and $2 in dividends on mandatorily redeemable capital stock.
In the first six months of 2021, the Bank paid dividends at an annualized rate of 5.47%, totaling $64, including $64 in dividends on capital stock and a de minimis amount in dividends on mandatorily redeemable capital stock. In the first quartersix months of 2020, the Bank paid dividends at an annualized rate of 7.00%5.99%, totaling $54,$94, including $52$90 in dividends on capital stock and $2$4 in dividends on mandatorily redeemable capital stock.
For the periods referenced above, the Bank paid dividends in cash. Dividends on capital stock are recognized as dividends on the Statements of Capital Accounts, and dividends on mandatorily redeemable capital stock are recognized as interest expense on the Statements of Income.
On AprilJuly 29, 2021, the Bank’s board of directors declared a quarterly cash dividend on the capital stock outstanding during the firstsecond quarter of 2021 at an annualized rate of 6.00%, totaling $34.$35. The Bank recorded the dividend on AprilJuly 29, 2021. The Bank expects to pay the dividend on May 11,August 10, 2021.
Excess Capital Stock – The Bank’s capital plan provides that the Bank may repurchase some or all of a shareholder’s excess capital stock, including any excess mandatorily redeemable capital stock, at the Bank’s discretion, subject to certain statutory and regulatory requirements. The Bank may also repurchase all of a member’s excess capital stock at a member’s request, at the Bank’s discretion, subject to certain statutory and regulatory requirements. A shareholder’s excess capital stock is defined as any capital stock holdings in excess of the shareholder’s minimum capital stock requirement, as established by the Bank’s capital plan. The Bank’s practice is to repurchase the surplus capital stock of all members and the excess capital stock of all former members on a daily schedule. Surplus capital stock is defined as any stock holdings in excess of 115% of a member’s minimum stock requirement. The Bank calculates the amount of stock to be repurchased each business day based on the shareholder’s capital stock outstanding after all stock transactions are completed for the day, ensuring that each member and former member would continue to meet its minimum capital stock requirement after the repurchase. The Bank may change this practice at any time. The Bank repurchased $47$294 and $431$707 in excess capital stock during the second quarter of 2021 and 2020, respectively, and $341 and $1,138 in excess capital stock during the first quartersix months of 2021 and 2020, respectively.
The Bank is required to redeem any mandatorily redeemable capital stock that is in excess of a former member’s minimum stock requirement on or after the expiration of the five-year redemption date. During the firstsecond quarter of 2021 and 2020, the Bank redeemed $1 and a de minimis amount respectively, in mandatorily redeemable capital stock, for which the five-year redemption period had expired, at its $100 par value.value per share. The stock was redeemed on the scheduled redemption dates or, for stock that was not excess stock on its scheduled redemption date because of outstanding activity with the Bank, on the first available repurchase date after the stock was no longer required to support outstanding activity with the Bank.

Note 10 — Segment Information
The Bank uses an analysis of financial results based on the financial components and adjusted net interest income of two operating segments, the advances-related business and the mortgage-related business, as well as other financial information, to review and assess financial performance and determine financial management strategies related to the operations of these 2 business segments. For purposes of segment reporting, adjusted net interest income includes income and expense associated with net settlements from economic hedges that are recorded in “Net gain/(loss) on derivatives” in other income, excludes interest income and expense associated with changes in fair value from fair value hedges that are recorded in the same line as the earnings effect of the hedged item, and excludes interest expense that is recorded in “Mandatorily redeemable capital stock.” Affordable Housing Program (AHP) assessments are not included in the segment reporting analysis but are incorporated into the Bank’s overall assessment of financial performance.
For more information on these operating segments, see “Item 8. Financial Statements and Supplementary Data – Note 13 – Segment Information” in the Bank’s 2020 Form 10-K.
The following table presents the Bank’s adjusted net interest income by operating segment and reconciles total adjusted net interest income to income before the AHP assessment for the three and six months ended March 31,June 30, 2021 and 2020.

Note 11 — Derivatives and Hedging Activities
General. The Bank may enter into interest rate swaps (including callable, putable, and basis swaps) and cap and floor agreements (collectively, interest rate exchange agreements or derivatives). Most of the Bank’s interest rate exchange agreements are executed in conjunction with the origination of advances or the issuance of consolidated obligations to create variable rate structures. The interest rate exchange agreements are generally executed at the same time the advances and consolidated obligations are transacted and generally have the same maturity dates as the related hedged instrument. The Bank transacts most of its derivatives with large banks and major broker-dealers.
For more information related to the Bank’s interest rate exchange agreement instruments and hedging activities, see “Item 8. Financial Statements and Supplementary Data – Note 14 – Derivatives and Hedging Activities” in the Bank’s 2020 Form 10-K. For more information related to the Bank’s accounting policies for derivatives, see “Item 8. Financial Statements and Supplementary Data – Note 1 – Summary of Significant Accounting Policies” in the Bank’s 2020 Form 10-K.

Credit Risk. The Bank is subject to credit risk from potential nonperformance by counterparties to the interest rate exchange agreements. All of the Bank’s agreements governing uncleared derivative transactions contain master netting provisions to help mitigate the credit risk exposure to each counterparty. The Bank manages counterparty credit risk through credit analyses and collateral requirements and by following the requirements of the Bank’s risk management policies, credit guidelines, and Finance Agency and other regulations. The Bank also requires credit support agreements on all uncleared derivatives.
For cleared derivatives, the clearinghouse is the Bank’s counterparty. The requirement that the Bank post initial and variation margin through a clearing agent to the clearinghouse exposes the Bank to institutional credit risk if the clearing agent fails to meet its obligations. The use of a clearinghouse, or central counterparty, lowers overall credit risk exposure because it employs standard valuation and initial and variation margin processes and is specifically designed to withstand remote but plausible counterparty default credit events. Variation margin is posted or collected for changes in the value of the portfolio, and initial margin is posted for changes in risk profile of the portfolio. The Bank has analyzed the enforceability of offsetting rights applicable to its cleared derivative transactions and determined that the exercise of those offsetting rights by a non-defaulting party under these transactions should be upheld under applicable bankruptcy law and Commodity Futures Trading Commission rules in the event of a clearinghouse or clearing agent insolvency and under applicable clearinghouse rules upon a non-insolvency-based event of default of the clearinghouse or clearing agent. Based on this analysis, the Bank presents a net derivative receivable or payable for all of its transactions through a particular clearing agent with a particular clearinghouse.
Based on the Bank’s credit analyses and the collateral requirements, the Bank does not expect to incur any credit losses on its derivative transactions.
The Bank’s agreements for uncleared derivative transactions contain provisions that link the Bank’s credit rating from Moody’s Investors Service and S&P Global Ratings to various rights and obligations. Certain of these
33

Notes to Financial Statements (continued)


derivative agreements provide that, if the Bank’s long-term debt rating falls below a specified rating (ranging from A3/A- to Baa3/BBB-), the Bank’s counterparty would have the right, but not the obligation, to terminate all of its outstanding derivative transactions with the Bank; the Bank’s agreements with its clearing agents for cleared derivative transactions have similar provisions with respect to the debt rating of FHLBank System consolidated bonds. If this occurs, the Bank may choose to enter into replacement hedges, either by transferring the existing transactions to another counterparty or entering into new replacement transactions, based on prevailing market rates. The aggregate fair value of all uncleared derivative instruments with credit risk-related contingent features that were in a net derivative liability position (before cash collateral and related accrued interest) at March 31,June 30, 2021, was $20,$13, for which the Bank had posted cash collateral of $18$12 in the ordinary course of business.
The Bank may present derivative instruments, related cash collateral received or pledged, and associated accrued interest by clearing agent or by counterparty when the netting requirements have been met.
The following tables present separately the fair value of derivative assets and derivative liabilities that have met the netting requirements, including the related collateral received from or pledged to counterparties as of March 31,June 30, 2021, and December 31, 2020.

Note 12 — Fair Value
The following fair value amounts have been determined by the Bank using available market information and the Bank’s best judgment of appropriate valuation methods. These estimates are based on pertinent information

available to the Bank at March 31,June 30, 2021, and December 31, 2020. Although the Bank 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 a portion of the Bank’s financial instruments, in certain cases fair values cannot be precisely quantified or verified and may change as economic and market factors and evaluation of those factors change. The Bank continues to refine its valuation methodologies as markets and products develop and the pricing for certain products becomes more or less transparent. While the Bank believes that its valuation methodologies are appropriate and consistent with those of other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a materially different estimate of fair value as of the reporting date. U.S. GAAP defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (i.e., an exit price). Therefore, the fair values are not necessarily indicative of the amounts that would be realized in current market transactions, although they do reflect the Bank’s judgment as to how a market participant would estimate the fair values. The fair value summary table does not represent an estimate of the overall market value of the Bank as a going concern, which would take into account future business opportunities and the net profitability of total assets and liabilities.

Fair Value Hierarchy. The fair value hierarchy is used to prioritize the fair value methodologies and valuation techniques as well as the inputs to the valuation techniques used to measure fair value for assets and liabilities carried at fair value on the Statements of Condition. The inputs are evaluated and an overall level for the fair value measurement is determined. This overall level is an indication of market observability of the fair value measurement for the asset or liability. The fair value hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). An entity must disclose the level within the fair value hierarchy in which the measurements are classified for all financial assets and liabilities measured on a recurring or non-recurring basis.
The application of the fair value hierarchy to the Bank’s financial assets and financial liabilities that are carried at fair value either on a recurring or non-recurring basis is as follows:
Level 1 – Quoted prices (unadjusted) for identical assets or liabilities in an active market that the reporting entity can access on the measurement date. An active market for the asset or liability is a market in which the transactions for the asset or liability occur with sufficient frequency and volume to provide pricing information on an ongoing basis.

Table of Contents
Federal Home Loan Bank of San Francisco
Notes to Financial Statements (continued)


Level 2 – Inputs other than quoted prices within Level 1 that are observable inputs for the asset or liability, either directly or indirectly. If the asset or liability has a specified (contractual) term, a Level 2 input must be observable for substantially the full term of the asset or liability. Level 2 inputs include the following: (1) quoted prices for similar assets or liabilities in active markets; (2) quoted prices for identical or similar assets or liabilities in markets that are not active; (3) inputs other than quoted prices that are observable for the asset or liability (e.g., interest rates and yield curves that are observable at commonly quoted intervals, and implied volatilities); and (4) inputs that are derived principally from or corroborated by observable market data by correlation or other means.
Level 3 – Unobservable inputs for the asset or liability.
A financial instrument’s categorization within the valuation hierarchy is based on the lowest level of input that is significant to the fair value measurement.
The following assets and liabilities, including those for which the Bank has elected the fair value option, are carried at fair value on the Statements of Condition as of March 31,June 30, 2021:
Trading securities
AFS securities
Certain advances
Derivative assets and liabilities
Certain consolidated obligation bonds
Certain other assets
For 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 periods presented, the Bank did not have any reclassifications for transfers in or out of level 3 of the fair value hierarchy.
Summary of Valuation Methodologies and Primary Inputs. For information related to the valuation methodologies and primary inputs used to develop the measurement of fair value for assets and liabilities that are measured at fair value on a recurring or nonrecurring basis in the Statements of Condition, see “Item 8. Financial Statements and Supplementary Data – Note 15 – Fair Value” in the Bank’s 2020 Form 10-K. There have been no significant changes in these valuation methodologies and primary inputs during the threesix months ended March 31,June 30, 2021.
Subjectivity of Estimates Related to Fair Values of Financial Instruments. Estimates of the fair value of financial assets and liabilities using the methodologies described above are subjective and require judgments regarding significant matters, such as the amount and timing of future cash flows, prepayment speed assumptions, expected interest rate volatility, methods to determine possible distributions of future interest rates used to value options, and the selection of discount rates that appropriately reflect market and credit risks. Changes in these judgments often have a material effect on the fair value estimates.

Fair Value Option. The fair value option provides an entity with an irrevocable option to elect fair value as an alternative measurement for selected financial assets, financial liabilities, unrecognized firm commitments, and written loan commitments not previously carried at fair value. It requires an entity to display the fair value of those assets and liabilities for which the entity has chosen to use fair value on the face of the Statements of Condition. Fair value is used for both the initial and subsequent measurement of the designated assets, liabilities, and commitments, with the changes in fair value recognized in net income. Interest income and interest expense on advances and consolidated bonds carried at fair value are recognized solely on the contractual amount of interest due or unpaid. Any transaction fees or costs are immediately recognized in non-interest income or non-interest expense.
For more information on the Bank’s election of the fair value option, see “Item 8. Financial Statements and Supplementary Data – Note 15 – Fair Values” in the Bank’s 2020 Form 10-K.

The Bank has elected the fair value option for certain financial instruments to assist in mitigating potential earnings volatility that can arise from economic hedging relationships in which the carrying value of the hedged item is not adjusted for changes in fair value. The potential earnings volatility associated with recording fair value changes of only the hedging derivative is the Bank’s primary reason for electing the fair value option for financial assets and liabilities that do not qualify for hedge accounting or that have not previously met or may be at risk for not meeting the hedge effectiveness requirements.
The following table summarizestables summarize the activity related to financial assets and liabilities for which the Bank elected the fair value option during the three and six months ended March 31,June 30, 2021 and 2020:

consolidated obligations recorded under the fair value option, the Bank determined that none of the remaining changes in fair value were related to instrument-specific credit risk for the three and six months ended March 31,June 30, 2021 and 2020. In determining that there has been no change in instrument-specific credit risk period to period, the Bank primarily considered the following factors:
The Bank is a federally chartered GSE, and as a result of this status, the consolidated obligations have historically received the same credit ratings as the government bond credit rating of the United States, even though they are not obligations of the United States and are not guaranteed by the United States.
The Bank is jointly and severally liable with the other FHLBanks for the payment of principal and interest on all consolidated obligations of each of the FHLBanks.

The following table presents the difference between the aggregate remaining contractual principal balance outstanding and aggregate fair value of advances and consolidated obligation bonds for which the Bank elected the fair value option at March 31,June 30, 2021, and December 31, 2020:

Note 13 — Commitments and Contingencies
As provided by the FHLBank Act or regulations governing the operations of the FHLBanks, all FHLBanks have joint and several liability for all FHLBank consolidated obligations, which are backed only by the financial resources of the FHLBanks. The joint and several liability regulation authorizes the Finance Agency to require any FHLBank to repay all or a portion of the principal or interest on consolidated obligations for which another FHLBank is the primary obligor. The regulations provide a general framework for addressing the possibility that an FHLBank may be unable to repay the consolidated obligations for which it is the primary obligor. The Bank has never been asked or required to repay the principal or interest on any consolidated obligation on behalf of another FHLBank, and as of March 31,June 30, 2021, and through the filing date of this report, does not believe that it is probable that it will be asked to do so. The par value of the outstanding consolidated obligations of the FHLBanks was $696,385$666,747 at March 31,June 30, 2021, and $746,722 at December 31, 2020. The par value of the Bank’s participation in consolidated obligations was $50,159$46,464 at March 31,June 30, 2021, and $60,606 at December 31, 2020. For more information on the joint and several liability regulation, see “Item 8. Financial Statements and Supplementary Data – Note 16 – Commitments and Contingencies” in the Bank’s 2020 Form 10-K.
Off-balance sheet commitments as of March 31,June 30, 2021, and December 31, 2020, were as follows:

Standby letters of credit are generally issued for a fee on behalf of members to support their obligations to third parties. If the Bank is required to make a payment for a beneficiary’s drawing under a letter of credit, the amount is immediately due and payable by the member to the Bank and is charged to the member’s demand deposit account

with the Bank. At March 31,June 30, 2021, the original terms of these standby letters of credit range from 1 daydays to 15 years, including a final expiration in 2035.2036.

The value of the Bank’s obligations related to standby letters of credit is recorded in other liabilities and amounted to $34$32 and $36 at March 31,June 30, 2021, and December 31, 2020, respectively. Standby letters of credit are fully collateralized at the time of issuance. Based on the Bank’s credit analyses of members’ financial condition and collateral requirements, the Bank deemed it unnecessary to record any additional liability for credit losses on the letters of credit outstanding or other off-balance sheet commitments as of March 31,June 30, 2021, and December 31, 2020.
There were no0 commitments to fund advances at March 31,June 30, 2021, and December 31, 2020. Advances funded under advance commitments are fully collateralized at the time of funding.

Readers of this report should not rely solely on the forward-looking statements and should consider all risks and uncertainties addressed throughout this report, as well as those discussed under “Item 1A. Risk Factors” in the Bank’s Annual Report on Form 10-K for the year ended December 31, 2020 (2020 Form 10-K).

Quarterly Overview
Net income for the firstsecond quarter of 2021 was $94$55 million, compared with a net lossincome of $8$88 million for the firstsecond quarter of 2020. The $102$33 million increasedecrease in net income relative to the prior-year period primarily reflected an increasea decrease in net interest income of $109$17 million, a decrease in other income/(loss) of $17 million, and an improvementa decline in provision for/(reversal of)recovery of credit losses of $45by $5 million. This wasThese decreases to net income were partially offset by a decrease in other expense of $4 million and a $2 million reduction in the Affordable Housing Program assessment, which reflected the decline in pre-assessment income.
The $17 million decrease in net interest income primarily reflected a decrease in interest-earning assets, an increase in net losses on designated fair value hedges of $39$11 million, and a decrease in prepayment fees of $4 million received on advances. These decreases to net interest income were partially offset by an improvement in interest rate spreads on interest-earning assets. The $17 million decrease in other income/(loss) was primarily attributable to an increase in net fair value losses associated with financial instruments carried at fair value, that was partially offset by an increasea decrease in net fair value gainslosses associated with non-hedge qualifying derivatives.
The $109 million increase in net interest income primarily reflected an increase of $64 million in net fair value gains on designated fair value hedges, an improvement in retrospective adjustment of the effective yields on mortgage loans and related delivery commitments of $38 million, and an increase in prepayment fees received on advances of $7 million. Additionally, the Bank recorded a reversal of credit losses of $6 million for the first quarter of 2021, primarily associated with certain private-label residential mortgage-backed securities (PLRMBS) classified as available-for-sale (AFS) and largely resulting from improved credit performance and an improved economic outlook. This reversal compares with a provision for credit losses of $39 million recorded for the first quarter of 2020 associated with certain PLRMBS classified as AFS, which primarily resulted from a significant decline in fair values in the first quarter of 2020.
At March 31,June 30, 2021, total assets were $57.9$54.2 billion, a decrease of $10.7$14.4 billion from $68.6 billion at December 31, 2020. TotalAdvances decreased $6.8 billion, to $24.2 billion at June 30, 2021, from $31.0 billion at December 31, 2020, as many members maintained significant deposit balances and liquidity resulting from the ongoing economic and financial market impacts of the COVID-19 pandemic, including government intervention. In addition, total investments decreased $7.7$6.8 billion, to $27.5$28.4 billion at March 31,June 30, 2021, from $35.2 billion at December 31, 2020. The majority of the decrease in investments primarily reflected a decreasereduction in U.S. Treasury securities and securities purchased under agreements to resell, U.S. Treasury securities, and MBS, thatwhich was partially offset by an increase in Federal funds sold, as the Bank continued to manage its liquidity. In addition, advances decreased $2.9 billion,MBS also contributed to $28.1 billion at March 31, 2021, from $31.0 billion at December 31, 2020, as many members maintained significant deposit balances and excess liquidity resulting from the economic impacts of the COVID-19 pandemic.decline in investments by $1.5 billion.
Accumulated other comprehensive income/(loss) (AOCI) increased by $137164 million during the firstsecond quarter of 2021, to $367$394 million at March 31,June 30, 2021, from $230 million at December 31, 2020. The increase in AOCI during the firstsecond quarter of 2021 primarily reflected higher fair values of MBS classified as AFS.available-for-sale.
On AprilJuly 29, 2021, the Bank’s board of directors declared a quarterly cash dividend on the capital stock outstanding during the firstsecond quarter of 2021 at an annualized rate of 6.00%. The dividend will total $34$35 million. The Bank recorded the dividend on AprilJuly 29, 2021, and expects to pay the dividend on May 11,August 10, 2021.
As of March 31,June 30, 2021, the Bank complied with all of its regulatory capital requirements. The Bank’s total regulatory capital ratio was 10.3%11.1%, exceeding the 4.0% requirement. The Bank had $6.0 billion in permanent capital, exceeding its risk-based capital requirement of $1.2$1.1 billion.
The Bank will continue to monitor the condition of its balance sheet, its financial performance, its capital position, overall financial market conditions, and other relevant information as the basis for determining the payment of dividends in future quarters.
Legislation has been introduced in the U.S. Senate and House of Representatives that, if enacted in its proposed form, would require that the FHLBanks set aside higher percentages of their earnings for their affordable housing and community investment programs than is currently required under the current law. The Bank is actively monitoring these proposals.
COVID-19 Pandemic Impact. In 2020, the COVID-19 pandemic impacted the financial markets and created substantial uncertainty about future economic activity and the Bank’s operating environment. In response, the federal government and the Federal Reserve used their full range of tools to support the economy, including fiscal stimulus and quantitative easing. At the end of the year,2020, the Federal Reserve maintained a Federal funds target range of
47

0.00% to 0.25%. The emergency measures taken by the federal government and the Federal Reserve helped facilitate liquidity and support stability in fixed income markets but contributed to the significant reduction in demand for advances demand from members. The Bank continued to meet its funding needs through the firstsecond quarter of 2021.

The Bank transitioned to remote work in mid-March 2020 and operatedcontinued to operate effectively with employees working remotely through the firstsecond quarter of 2021. The Bank has assessed the remote work environment and has taken measures to mitigate cyber-security risks and operational challenges that could affect the Bank’s ability to conduct business or increase the risk of operational incidents and errors. The ultimate impact of the disruption caused by the pandemic continues to be uncertain. Possible adverse impacts as a result of the Bank’s workforce working remotely may include, but are not limited to, increased risk of operational incidents, cyber-security threats, and operational challenges that could affect the Bank’s ability to conduct business or increase the risk of operational errors.
TheBecause the Bank relies on vendors and other third parties to perform certain critical services. Ifservices, should one of our critical vendors or third parties experiencesexperience a failure or any interruption to their business duerelated to the COVID-19 pandemic, including as a result of stay-at-home requirements and using a hybrid onsite and remote workforce, the Bank may be unable to conduct and effectively manage certain parts of its business.
To reduce the risk of the operational impact of the pandemic, the Bank maintains a Board-approved Business Continuity Management Program, along with a Crisis Management Plan and Business Continuity Plans (BCPs), that are updated and tested annually. The Bank’s BCPs provide procedures to ensure personnel safety and welfare, to safeguard the Bank’s assets (including physical property and information), and to permit the continued operations of the Bank in the event of a short-term disruption or long-term catastrophic event. The Bank’s BCPs contain operating procedures for all critical processes and identify resources and staff necessary to continue operations based on business-defined recovery time objectives and communication requirements for internal and external stakeholders.
The impact of the COVID-19 pandemic, and related government and public actions taken in response, on the U.S. economy and the Bank are continuing to evolve, and the full duration and impact of the pandemic and subsequent governmental and public actions areremain uncertain.
As the COVID-19 pandemic persists, the demand Demand for advances may continue to remain low or decrease because of furtherthe impact of government intervention,stimulus on member liquidity, Federal Reserve Board policies (including lower interest rates set by the Federal Open Market Committee (FOMC)), and reduced member asset activity. The risk of credit losses is likely to increase. The Bank believes that lower demand from the Bank’s members for advances will likely continue into the foreseeable future. The risk of credit losses is likely to increase. In addition, other possible effects on the Bank from the COVID-19 pandemic on the Bank may include, but are not limited to, further disruption to the Bank’s members, uncertainties in the credit markets, and a decline in the fair value of assets or an increase in the write-down of investments.
The Bank has implemented certain relief measures to help members serve customers affected by the COVID-19 pandemic, such as accommodating forbearance and modifications to pledged loan collateral and allowing electronic signatures on loan documentation in specific circumstances. The board of directors also approved subsidized credit and grant programs to assist our members in responding to the challenges brought about by the COVID-19 pandemic.
Management will continue to monitor the COVID-19 pandemic’s impact on the Bank’s financial condition and operations, including the Bank’s liquidity, advance levels, funding spreads, and workforce effectiveness.

(3)Net interest margin is net interest income (annualized) divided by average interest-earning assets.
(4)This ratio is calculated as dividends per share divided by net income per share.
(5)This ratio is calculated as regulatory capital divided by total assets. Regulatory capital includes retained earnings, Class B capital stock, and mandatorily redeemable capital stock (which is classified as a liability), but excludes AOCI.

Results of Operations
Net Interest Income. The primary source of the Bank’s earnings is net interest income, which is the interest earned on advances, mortgage loans, and investments, including net accretion of related income from improvement in expected cash flows on certain PLRMBS that were other-than-temporarily-impaired prior to January 1, 2020, less interest paid on consolidated obligations, deposits, mandatorily redeemable capital stock, and other borrowings. The Average Balance Sheets tabletables that follows presentsfollow present the average balances of interest-earning asset categories and the sources that funded those interest-earning assets (liabilities and capital) for the three and six months ended March 31,June 30, 2021 and 2020, together with the related interest income and expense. ItThey also presentspresent the average rates on total interest-earning assets and the average costs of total funding sources.

For securities previously identified as other-than-temporarily impaired pursuant to the impairment guidance in effect prior to January 1, 2020, the Bank updates its estimate of future estimated cash flows on a regular basis. If there is no additional credit loss on the security, the yield of the security is adjusted upward on a prospective basis and accreted into interest income when there is a significant increase in the expected cash flows. As a result of improvements in the estimated cash flows of securities previously identified as other-than-temporarily impaired, the net accretion of income is likely to continue to be a positive source of net interest income in future periods.
Member demand for wholesale funding from the Bank can vary greatly depending on a number of factors, including economic and market conditions, competition from other wholesale funding sources, member deposit inflows and outflows, the activity level of the primary and secondary mortgage markets, and strategic decisions made by individual member institutions. As a result, Bank asset levels and operating results may vary significantly from period to period.

Under the fair value option, the Bank elected to carry certain assets and liabilities at fair value. In general, transactions elected for the fair value option are in economic hedge relationships. Gains or losses on these transactions are generally offset by losses or gains on the derivatives that economically hedge these instruments.
The net gains/(losses) on advances and consolidated obligation bonds held under the fair value option were primarily driven by the effects of changes in market interest rates, interest rate spreads, interest rate volatility, and other market factors relative to the actual terms on the advances and consolidated obligation bonds during the period.

Additional information about advances and consolidated obligation bonds held under the fair value option is provided in “Item 1. Financial Statements – Note 12 – Fair Value.”
Net Gain/(Loss) on Derivatives – Under the accounting for derivative instruments and hedging activities, the Bank is required to carry all of its derivative instruments on the Statements of Condition at fair value. Certain derivatives are associated with assets or liabilities but do not qualify as fair value hedges under the accounting for derivative instruments and hedging activities. These economic hedges are recorded on the Statements of Condition at fair value with the unrealized gain or loss recorded in earnings without any offsetting unrealized gain or loss from the associated asset or liability.
The following table shows the accounting classification of economic hedges and the categories of hedged items that contributed to the gains and losses on derivatives that were recorded in “Net gain/(loss) on derivatives” in the firstsecond quarter of 2021 and 2020.

During the firstsecond quarter of 2021, net gainslosses on derivatives totaled $18$8 million compared to net losses of $147$14 million in the firstsecond quarter of 2020. These amounts included expense of $24$21 million and expense of $8$10 million resulting from net settlements on derivative instruments used in economic hedges in the firstsecond quarter of 2021 and 2020, respectively. Excluding the impact of income or expense from net settlements on derivative instruments used in economic hedges, the net gains or losses on economic hedges were primarily associated with the effects of changes in market interest rates, interest rate spreads, interest rate volatility, and other market factors during the period.
The ongoing impact of these valuation adjustments on the Bank cannot be predicted and the effects of these valuation adjustments may lead to significant volatility in future earnings, including earnings available for dividends.

The net interest margin was 96 basis points for the first six months of 2021, 61 basis points higher than the net interest margin for the first six months of 2020, which was 35 basis points. The net interest spread was 94 basis points for the first six months of 2021, 66 basis point higher than the net interest spread for the first six months of 2020, which was 28 basis points. These increases were primarily a result of an increase in net gains on designated fair value hedges, an improvement in retrospective adjustment of the effective yields on mortgage loans and related delivery commitments, and lower funding costs.

Under the fair value option, the Bank elected to carry certain assets and liabilities at fair value. In general, transactions elected for the fair value option are in economic hedge relationships. Gains or losses on these transactions are generally offset by losses or gains on the derivatives that economically hedge these instruments.
The net gains/(losses) on advances and consolidated obligation bonds held under the fair value option were primarily driven by the effects of changes in market interest rates, interest rate spreads, interest rate volatility, and other market factors relative to the actual terms on the advances and consolidated obligation bonds during the period.
Additional information about advances and consolidated obligation bonds held under the fair value option is provided in “Item 1. Financial Statements – Note 12 – Fair Value.”

During the first six months of 2021, net gains on derivatives and hedging activities totaled $10 million compared to net losses of $161 million in the first six months of 2020. These amounts included expense of $45 million and expense of $18 million resulting from net settlements on derivative instruments used in economic hedges in the first six months of 2021 and 2020, respectively. Excluding the impact of income or expense from net settlements on derivative instruments used in economic hedges, the net gains or losses on fair value and economic hedges were primarily associated with the effects of changes in market interest rates, interest rate spreads, interest rate volatility, and other market factors during the period.
Additional information about derivatives and hedging activities is provided in “Item 1. Financial Statements – Note 11 – Derivatives and Hedging Activities.”
Return on Average Equity. Return on average equity (ROE) was 6.04%3.45% (annualized) for the firstsecond quarter of 2021, compared to (0.46)%5.66% (annualized) for the second quarter of 2020. The decrease primarily reflected lower net income for the second quarter of 2021, which decreased 38%, from $88 million in the second quarter of 2020 to $55 million in the second quarter of 2021, and an increase in average equity from $6.2 billion in the second quarter of 2020 to $6.4 billion in the second quarter of 2021.
ROE was 4.72% (annualized) for the first quartersix months of 2021, compared to 2.47% (annualized) for the first six months of 2020.

capital stock. In the first six months of 2020, the Bank paid dividends at an annualized rate of 5.99%, totaling $94 million, including $90 million in dividends on capital stock and $4 million in dividends on mandatorily redeemable capital stock.
The Bank paid these dividends in cash. Dividends on capital stock are recognized as dividends on the Statements of Capital Accounts, and dividends on mandatorily redeemable capital stock are recognized as interest expense on the Statements of Income.
On AprilJuly 29, 2021, the Bank’s board of directors declared a cash dividend on the capital stock outstanding during the firstsecond quarter of 2021 at an annualized rate of 6.00%, totaling $34$35 million. The Bank recorded the dividend on AprilJuly 29, 2021. The Bank expects to pay the dividend on May 11,August 10, 2021.
The Bank’s Excess Stock Repurchase, Retained Earnings, and Dividend Framework (Framework) assesses the level and adequacy of retained earnings and establishes amounts to be retained in restricted retained earnings, which are not made available in the current dividend period, and maintains an amount of total retained earnings at least equal to its required retained earnings as described in the Framework. As determined using the Bank’s methodology, the required level of total retained earnings had ranged from $2.4 billion to $2.5 billion during all of 2019 and continuing through September 2020. In September 2020, the methodology was further revised and resulted in a required level of retained earnings of $2.9 billion. In January 2021, the methodology was further revised and resulted in a required level of retained earnings of $1.9 billion. In July 2021, the methodology was further revised and resulted in a required level of retained earnings of $1.5 billion. The Bank satisfies its retained earnings requirement with both restricted retained earnings (i.e., amounts related to the Joint Capital Enhancement Agreement) and unrestricted retained earnings. The Bank’s retained earnings requirement may be changed at any time. The board of directors periodically reviews the retained earnings methodology and analysis to determine whether any adjustments are appropriate. Total restricted retained earnings were $761 million as of March 31,June 30, 2021, and December 31, 2020.

option. The change in the net unrealized gains on the hedged advances and advances carried at fair value from December 31, 2020, to March 31,June 30, 2021, was primarily attributable to the effects of changes in market interest rates, interest rate spreads, interest rate volatility, and other market factors relative to the terms on the Bank’s advances during the period.

As provided by the FHLBank Act or regulations governing the operations of the FHLBanks, all FHLBanks have joint and several liability for all FHLBank consolidated obligations. The joint and several liability regulation authorizes the Finance Agency to require any FHLBank to repay all or a portion of the principal or interest on consolidated obligations for which another FHLBank is the primary obligor. The Bank has never been asked or required to repay the principal or interest on any consolidated obligation on behalf of another FHLBank, and as of March 31,June 30, 2021, and through the filing date of this report, does not believe that it is probable that it will be asked to do so. The par value of the outstanding consolidated obligations of the FHLBanks was $696.4$666.7 billion at March 31,June 30, 2021, and $746.7 billion at December 31, 2020.
Changes in the long-term credit ratings of individual FHLBanks do not necessarily affect the credit rating of the consolidated obligations issued on behalf of the FHLBanks. Rating agencies may change or withdraw a rating from time to time because of various factors, including operating results or actions taken, business developments, or changes in their opinion regarding, among other factors, the general outlook for a particular industry or the economy.
Certain Bank assets, liabilities, and derivatives are indexed to LIBOR. The Bank recognizes that the impending discontinuation of LIBOR presents risks and challenges that could have an impact on the Bank’s business. For information about the risks to the Bank from discontinuation of LIBOR, see “Item 1A. Risk Factors” in the Bank’s 2020 Form 10-K. Accordingly, the Bank has established the LIBOR Transition Working Group, led by the Chief Financial Officer, and developed a LIBOR Phase Out Transition Plan (Transition Plan). Among other things, the Transition Plan addresses three key strategies to mitigate the risks to the Bank associated with the discontinuation of LIBOR: (i) execute hedging strategies that permit alternative reference rates, including the Secured Overnight Financing Rate (SOFR), (ii) transact SOFR-indexed advances and bonds, and (iii) where practicable, implement improved fallback provisions for the discontinuation of LIBOR in new and legacy contracts. In addition, the Transition Plan limits new LIBOR transactions with maturities beyond the end of 2021 consistent with the limits set by the Finance Agency’s Supervisory Letter issued on September 27, 2019. The Transition Plan states that the Bank’s Asset and Liability Management Committee has primary responsibility for driving the transition from

LIBOR to SOFR and that the Bank’s Business Development Committee is responsible for advance product development to facilitate our members’ transition from LIBOR to an alternative index.
On October 21, 2020, the Finance Agency issued a Supervisory Letter to the FHLBanks that required each FHLBank to adhere to the Fallbacks Protocol (Protocol) by December 31, 2020, and, to the extent necessary, to amend any bilateral agreements regarding the adoption of the Protocol by December 15, 2020. On October 23, 2020, International Swaps and Derivatives Association, Inc. (ISDA) launched the Supplement to the 2006 ISDA Definitions (Supplement) and the ISDA 2020 Interbank Offered Rate (IBOR) Fallbacks Protocol (Protocol).Protocol. Both the Supplement and the Protocol took effect on January 25, 2021. As part of its LIBOR transition efforts, the Bank and all of its uncleared derivatives counterparties have adhered to the Protocol. On that date,January 25, 2021, all of the Bank’s outstanding legacy bilateral derivative transactions subject to Protocol-covered agreements (including ISDA agreements) that incorporate certain covered ISDA definitional booklets and referencereferenced a covered IBOR, including U.S. dollar LIBOR, were

Table of Contents
amended to apply the new ISDA-recommended IBOR fallbacks in the event of the relevant IBOR’s cessation. Both the Bank and its relevant counterparty must have adhered to the Protocol to effectively amend legacy derivative contracts, or the parties must bilaterally agree to include amended legacy contracts to address LIBOR fallbacks. The Protocol will remain open for adherence after this effective date. As of January 25, 2021, new and future derivative contracts are subject to the relevant IBOR fallbacks set forth in the Supplement. On October 21, 2020, the Finance Agency issued a Supervisory Letter to the FHLBanks that required each FHLBank to adhere to the Protocol by December 31, 2020, and, to the extent necessary, to amend any bilateral agreements regarding the adoption of the Protocol by December 15, 2020. As part of its LIBOR Transition efforts, the Bank and all of its uncleared derivatives counterparties have adhered to the Protocol.
In July 2017, the United Kingdom’s Financial Conduct Authority, which regulates LIBOR, announced that after 2021 it will no longer persuade or compel banks to submit rates for the calculation of LIBOR. On March 5, 2021, the United Kingdom’s Financial Conduct Authority further announced that LIBOR will either cease to be provided by any administrator or no longer be representative immediately after December 31, 2021, in the case of 1-week and 2-month U.S. dollar LIBOR, and immediately after June 30, 2023, in the case of the remaining U.S. dollar LIBOR settings.
Although the Financial Conduct Authority does not expect LIBOR to become unrepresentative before the applicable cessation date and intends to consult on requiring the administrator of LIBOR to continue publishing LIBOR of certain currencies and tenors on a non-representative, synthetic basis for a period after the applicable cessation date, there is no assurance that LIBOR, of any particular currency or tenor, will continue to be published or be representative through any particular date. The Financial Conduct Authority’s announcements constitutes an index cessation event under the Protocol and Supplement, and as a result, the fallbacks spread adjustment for each tenor iswas fixed as of the date of the announcement.
At March 31,June 30, 2021, the Bank had no exposure to LIBOR settings that cease immediately after December 31, 2021.
The following tables present LIBOR-indexed variable rate financial instruments for LIBOR tenors that cease or will no longer be representative immediately after June 30, 2023, by due date or termination date at March 31,June 30, 2021, and December 31, 2020.

Segment Information
The Bank uses an analysis of financial results based on the financial components and adjusted net interest income of two operating segments, the advances-related business and the mortgage-related business, as well as other financial information, to review and assess financial performance and determine financial management strategies related to the operations of these two business segments. For purposes of segment reporting, adjusted net interest income includes income and expense associated with net settlements from economic hedges that are recorded in “Net gain/(loss) on derivatives” in other income, excludes interest income and expense associated with changes in fair value of the derivative hedging instrument and the hedged item attributable to the hedged risk for designated fair value hedges that are recorded in net interest income, and excludes interest expense that is recorded in “Mandatorily redeemable capital stock.” AHP assessments are not included in the segment reporting analysis but are incorporated into the Bank’s overall assessment of financial performance. For a reconciliation of the Bank’s operating segment adjusted net interest income to the Bank’s total net interest income, see “Item 1. Financial Statements – Note 10 – Segment Information.”
Advances-Related Business. The advances-related business consists of advances and other credit products, related financing and hedging instruments, liquidity and other non-MBS investments associated with the Bank’s role as a liquidity provider, and capital. Assets associated with this segment decreased $9.2$12.3 billion to $41.7$38.6 billion (72%(71% of total assets) at March 31,June 30, 2021, from $50.9 billion (74% of total assets) at December 31, 2020.
Adjusted net interest income for this segment is derived primarily from the difference, or spread, between the yield on advances and non-MBS investments and the cost of the consolidated obligations funding these assets, including the net settlements from associated interest rate exchange agreements, and from earnings attributed to the Bank’s capital stock and retained earnings.
Adjusted net interest income for this segment was $51$49 million in the firstsecond quarter of 2021, a decrease of $12$23 million, or 19%32%, compared to $63$72 million in the second quarter of 2020. Adjusted net interest income for this segment was $101 million in the first quartersix months of 2021, a decrease of $34 million, or 25%, compared to $135 million in the first six months of 2020. This decrease wasThese decreases were primarily due to lower balances of advances and other credit products combined with a decline in spreads on advances-related assets due to lower interest rates and lower balancesrates.

may significantly increase and decrease from period to period because of a member’s liquidity and financial strategies.
As of March 31,June 30, 2021, advances outstanding to the Bank’s top five borrowers and their affiliates decreased by $1.6$3.6 billion from the Bank’s top five borrowers and their affiliates as of December 31, 2020, and advances outstanding to the Bank’s other borrowers decreased by $1.0$2.9 billion. Advances to the top five borrowers decreased to $17.9$15.9 billion at March 31,June 30, 2021, from $19.5 billion at December 31, 2020, including First Republic Bank, whose advances and capital stock exceeded 10% of the Bank’s total advances and capital stock, respectively, as of March 31,June 30, 2021, as presented in “Item 1. Financial Statements – Note 4 – Advances – Concentration Risk” and “Item 1. Financial Statements – Note 9 – Capital – Concentration.” The $2.6$6.5 billion decrease in advances outstanding reflected a $1.5$5.2 billion decrease in fixed rate advances, and a $1.1 billion decrease in adjustable rate advances, and a $0.2 billion decrease in variable rate advances.
The Bank has a significant long-term funding arrangement with a borrower that had, in prior periods, significantly contributed to the level of outstanding advances and may significantly contribute to the level of outstanding advances in the foreseeable future.
The components of the advances portfolio at March 31,June 30, 2021, and December 31, 2020, are presented in the following table.

Non-MBS Investments The Bank’s non-MBS investment portfolio consists of financial instruments that are used primarily to facilitate the Bank’s role as a cost-effective provider of credit and liquidity to members and to support the operations of the Bank. The Bank’s total non-MBS investment portfolio was $12.9$14.1 billion and $19.4 billion as of March 31,June 30, 2021, and December 31, 2020, respectively. The decrease in the total size of the non-MBS investment portfolio primarily reflected a decrease in securities purchased under agreements to resell and U.S. Treasury securities, that was partially offset by an increase in Federal funds sold, as the Bank continued to manage its liquidity.
Interest rate payment terms for non-MBS investments classified as trading and AFS at March 31,June 30, 2021, and December 31, 2020, are detailed in the following table:

Borrowings – Total liabilities (primarily consolidated obligations) funding the advances-related business decreased to $35.3$32.2 billion at March 31,June 30, 2021, from $44.7 billion at December 31, 2020. For further information and discussion of the Bank’s joint and several liability for FHLBank consolidated obligations, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations Financial Condition” and “Item 1. Financial Statements – Note 13 – Commitments and Contingencies.”
To meet the specific needs of certain investors, fixed and adjustable rate consolidated obligation bonds may contain embedded call options or other features that result in complex coupon payment terms. When these types of consolidated obligation bonds are issued on behalf of the Bank, typically the Bank simultaneouslytypically enters into interest rate exchange agreements with features that offset the complex features of the bonds and, in effect,to convert the bonds to adjustable rate instruments. For example, the Bank may issue fixed rate callable bonds and simultaneously execute an interest rate exchange agreement with call features to offset the call options embedded in the callable bonds.
At March 31,June 30, 2021, the notional amount of interest rate exchange agreements associated with the advances-related business totaled $55.5$58.2 billion, of which $26.0$23.3 billion were hedging advances, $16.5$22.1 billion were hedging consolidated obligations, $6.0$4.1 billion were economically hedging non-MBS investments, and $7.0$8.7 billion were offsetting derivatives. At December 31, 2020, the notional amount of interest rate exchange agreements associated

with the advances-related business totaled $67.4 billion, of which $28.5 billion were hedging advances, $20.7 billion were hedging consolidated obligations, $7.1 billion were economically hedging non-MBS investments, and $11.1 billion were offsetting derivatives. The hedges associated with advances and consolidated obligations were primarily used to convert the fixed rate cash flows of the advances and consolidated obligations to adjustable rate cash flows or to manage the interest rate sensitivity and net repricing gaps of assets, liabilities, and interest rate exchange agreements.
FHLBank System consolidated obligation bonds and discount notes, along with similar debt securities issued by other GSEs such as Fannie Mae and Freddie Mac, are generally referred to as agency debt. The costs of debt issued by the FHLBanks and the other GSEs generally rise and fall with increases and decreases in general market interest rates.
In early March 2020, the FOMC stated that the COVID-19 outbreak presented evolving risks to economic activity. Consequently, the FOMC decided to lower the target range for the Federal funds rate by 50 basis points, to a target range of 1.00% to 1.25%, 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, to a target range of 0.00% to 0.25%, 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. In the weeks before and after the early March 2020 Federal funds target rate cut, interest rates declined significantly. Since the end of the first quarter of 2020, financial conditions have improved, in part because of the monetary and fiscal stimulus measures taken, and the Bank continues to be able to meet its funding needs. The following table presents a comparison of selected market interest rates as of March 31,June 30, 2021, and December 31, 2020.

Mortgage-Related Business. The mortgage-related business consists of MBS investments, mortgage loans acquired through the Mortgage Partnership Finance® (MPF®) Program, and the related financing and hedging instruments. (“Mortgage Partnership Finance,” “MPF,” and “MPF Xtra” are registered trademarks of the FHLBank of Chicago.) Adjusted net interest income for this segment is derived primarily from the difference, or spread, between the yield on the MBS investments and mortgage loans and the cost of the consolidated obligations funding those assets, including the net settlements from associated interest rate exchange agreements.
Assets associated with this segment were $16.2$15.6 billion (28%(29% of total assets) at March 31,June 30, 2021, and $17.8 billion at December 31, 2020 (26% of total assets).
Adjusted net interest income for this segment was $78$60 million in the second quarter of 2021, a decrease of $15 million, or 20%, from $75 million in the second quarter of 2020. The quarterly decrease was primarily a result of lower earnings from lower balances of mortgage-related products and a smaller reversal of prior period expected credit losses, partially offset by higher spreads from lower funding costs. Adjusted net interest income for this segment was $138 million in the first quartersix months of 2021, an increase of $66$51 million, or 550%59%, from $12$87 million in the first quartersix months of 2020. This increase was primarily due to a reversalresult of prior period expected credit losses,higher spreads from lower funding costs, an improvement in retrospective adjustment of the effective yields on mortgage loans and related delivery commitments, and higher spreads from lower funding costs,a reversal of prior period expected credit losses, partially offset by lower earnings due tofrom lower balances of mortgage-related products.

Interest Rate Exchange Agreements
A derivative transaction or interest rate exchange agreement is a financial contract whose fair value is generally derived from changes in the value of an underlying asset or liability. The Bank uses interest rate swaps; interest rate cap and floor agreements; and callable and putable interest rate swaps (collectively, interest rate exchange agreements) to manage its exposure to market risks inherent in its ordinary course of business, including its lending, investment, and funding activities. For more information on the Bank’s interest rate exchange agreements by type of hedged item, hedging instrument, associated hedging strategy, accounting designation as specified under the accounting for derivative instruments and hedging activities, and notional amount, and the primary strategies that the Bank employs for using interest rate exchange agreements and the associated market risks, see “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations – Risk Management – Interest Rate Exchange Agreements” in the Bank’s 2020 Form 10-K.

Liquidity and Capital Resources
The Bank’s financial strategies are designed to enable the Bank to expand and contract its assets, liabilities, and capital as membership composition and member credit needs change. The Bank’s liquidity and capital resources are designed to support its financial strategies. The Bank’s primary source of liquidity is its access to the debt capital markets through consolidated obligation issuance. The maintenance of the Bank’s capital resources is governed by its capital plan.
Liquidity
The Bank seeks to maintain the liquidity necessary to repay maturing consolidated obligations for which it is the primary obligor, meet other obligations and commitments, and meet expected and unexpected member credit

demands. The Bank monitors its financial position to maintain ready access to available funds to meet normal transaction requirements, take advantage of appropriate investment opportunities, and manage unforeseen liquidity demands.
The Bank generally manages operational, contingent, and refinancing risks using a portfolio of cash and short-term investments and access to the debt capital markets. In addition, the Bank maintains alternate sources of funds, detailed in its contingent liquidity plan, which also includes an explanation of how sources of funds may be allocated under stressed market conditions, such as short-term operational disruptions at the Bank or the Office of Finance or short-term disruptions in the debt capital markets.
The Finance Agency has established base case liquidity guidelines that each FHLBank maintain sufficient liquidity at least equal to its anticipated cash outflows, assuming no new consolidated obligation issuance, renewal of all maturing advances, a specified percentage drawdown on letters of credit balances, and certain Treasury investments as a source of funds. The Finance Agency’s guidance provides that base case liquidity should generally be maintained for 10 to 30 days. The Bank actively monitors and manages refinancing risk. Finance Agency guidance specifies tolerance levels related to the size of each FHLBank’s funding gaps to measure refinancing risk as the

Table of Contents
difference between assets and liabilities that are scheduled to mature during a specified period, expressed as a percentage of total assets. The guidance limits three-month and one-year funding gaps generally between the range of –10% to –20% and –25% to –35%, respectively. Funding gaps are measured at monthend, using the average ratio for the three most recent monthends.
In addition to the Finance Agency’s guidelines on contingent liquidity, the Bank models its cash commitments and expected cash flows on a daily basis to determine its projected liquidity position. If a market or operational disruption occurred that prevented the issuance of new consolidated obligations, the Bank could meet its obligations by: (i) allowing short-term liquid investments to mature, (ii) using eligible securities as collateral for repurchase agreement borrowings, and (iii) if necessary, allowing advances to mature without renewal. In addition, the Bank may be able to borrow on a short-term unsecured basis from other financial institutions (Federal funds purchased) or other FHLBanks (inter-FHLBank borrowings).
As of March 31,June 30, 2021, and December 31, 2020, the Bank held total sources of funds in an amount that would have allowed the Bank to meet its liquidity needs without issuing new consolidated obligations for over ten days, in accordance with the Finance Agency guidance. In addition, the Bank’s funding gap positions as of March 31,June 30, 2021, and December 31, 2020, were within the tolerance levels provided by the Finance Agency guidance.

Management’s Discussion and Analysis of Financial Condition and Results of Operations – Risk Management – Liquidity Risk” in the Bank’s 2020 Form  10-K.

Regulatory Capital Requirements
Under the Housing and Economic Recovery Act of 2008 (Housing Act), the Director of the Finance Agency is responsible for setting the risk-based capital standards for the FHLBanks. The FHLBank Act and regulations governing the operations of the FHLBanks require that the Bank’s minimum capital stock requirement for shareholders must be sufficient to enable the Bank to meet its regulatory requirements for total capital, leverage capital, and risk-based capital. The Bank must maintain: (i) total regulatory capital in an amount equal to at least 4% of its total assets, (ii) leverage capital in an amount equal to at least 5% of its total assets, and (iii) permanent capital in an amount that is greater than or equal to its risk-based capital requirement.
Beginning in February 2020, theThe Finance Agency issued guidance that augmented existing statutory and regulatory capital requirements to requirerequires each FHLBank to maintain a ratio of at least two percent2% of capital stock to total assets in order to help preserve the cooperative structure incentives that encourage members to remain fully engaged in the oversight of their investment in the FHLBank. The Finance Agency will consider the proportion of capital stock to assets, measured on a daily average basis at monthend, when assessing each FHLBank’s capital management practices. As of MarchJune 30, 2021, and December 31, 2021,2020, the Bank complied with this capital guidance.
70

Table of Contents
Because the Bank issues only Class B stock, regulatory capital and permanent capital for the Bank are both composed of retained earnings and Class B stock, including mandatorily redeemable capital stock (which is classified as a liability for financial reporting purposes). Regulatory capital and permanent capital do not include AOCI. Leverage capital is defined as the sum of permanent capital, weighted by a 1.5 multiplier, plus non-permanent capital.
The risk-based capital requirement is equal to the sum of the Bank’s credit risk, market risk, and operations risk capital requirements, all of which are calculated in accordance with the rules and regulations of the Finance Agency. The Finance Agency may require an FHLBank to maintain a greater amount of permanent capital than is required by the risk-based capital requirement as defined.
The following table shows the Bank’s compliance with the Finance Agency’s capital requirements at March 31,June 30, 2021, and December 31, 2020. The Bank’s risk-based capital requirement decreased to $1.2$1.1 billion at March 31,June 30, 2021, from $1.4 billion at December 31, 2020.

Risk Management
The Bank has an integrated corporate governance and internal control framework designed to support effective management of the Bank’s business activities and the risks inherent in these activities. As part of this framework, the Bank’s board of directors has adopted a Risk Governance Policy that outlines the key roles and responsibilities of the board of directors and management and sets forth how the Bank is organized to achieve its risk management objectives, including the implementation of the Bank’s strategic objectives, risk management strategies, corporate governance, and standards of conduct. The policy also establishes the Bank’s risk governance organizational structure and identifies the general roles and responsibilities of the board of directors and management in establishing risk management policies, procedures, and guidelines; in overseeing the enterprise risk profile; and in implementing enterprise risk management processes and business strategies. The policy establishes an independent risk oversight function to identify, assess, measure, monitor, and report on the enterprise risk profile and risk management capabilities of the Bank. For more information, see “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations – Risk Management” in the Bank’s 2020 Form 10-K.
Advances. The Bank manages the credit risk of advances and other credit products by setting the credit and collateral terms available to individual members and housing associates based on their creditworthiness and on the quality and value of the assets they pledge as collateral. The Bank also has procedures to assess the mortgage loan quality and documentation standards of institutions that pledge mortgage loan collateral. In addition, the Bank has collateral policies and restricted lending procedures in place to help manage its exposure to institutions that experience difficulty in meeting their capital requirements or other standards of creditworthiness. These credit and collateral policies balance the Bank’s dual goals of meeting the needs of members and housing associates as a reliable source of liquidity and mitigating credit risk by adjusting credit and collateral terms in view of deterioration in creditworthiness. The Bank has never experienced a credit loss on an advance.

Table of Contents
Pursuant to the Bank’s lending agreements with its borrowers, the Bank limits extensions of credit to individual borrowers to a percentage of the market value or unpaid principal balance of the borrower’s pledged collateral, known as the borrowing capacity, which the Bank can change from time to time. The borrowing capacity percentage varies according to several factors, including the charter type of the institution, the collateral type, the value assigned to the collateral, the results of the Bank’s collateral field review of the borrower’s collateral, the pledging method used for loan collateral (specific identification or blanket lien), the amount of loan data provided (detailed or summary reporting), the data reporting frequency (monthly or quarterly), the borrower’s financial strength and condition, and any institution-specific collateral risks. Under the terms of the Bank’s lending agreements, the aggregate borrowing capacity of a borrower’s pledged eligible collateral must meet or exceed the total amount of the borrower’s outstanding advances, other extensions of credit, and certain other borrower obligations and liabilities.
In addition, the total amount of advances made available to each member or housing associate may be limited by the financing availability assigned by the Bank, which is generally expressed as a percentage of the member’s or
64

Table of Contents
housing associate’s assets, which the Bank can change from time to time. The amount of financing availability is generally determined by the creditworthiness of the member or housing associate.
When a nonmember financial institution acquires some or all of the assets and liabilities of a member, including outstanding advances and Bank capital stock, the Bank may allow the advances to remain outstanding, at its discretion. The nonmember borrower is required to meet the Bank’s applicable credit, collateral, and capital stock requirements, including requirements regarding creditworthiness and collateral borrowing capacity.
The following tables present a summary of the status of the credit outstanding and overall collateral borrowing capacity of the Bank’s member and nonmember borrowers as of March 31,June 30, 2021, and December 31, 2020.

Based on the collateral pledged as security for advances, the Bank’s credit analyses of borrowers’ financial condition, and the Bank’s credit extension and collateral policies, the Bank expects to collect all amounts due according to the contractual terms of the advances. Therefore, no allowance for credit losses on advances is deemed necessary by the Bank. The Bank has never experienced any credit losses on advances.
Securities pledged as collateral are assigned borrowing capacities that reflect the securities’ market valuations and market liquidation risks.

With respect to loan collateral, most borrowers may choose to pledge loan collateral by specific identification or under a blanket lien. Insurance companies, CDFIs, and housing associates are required to pledge loan collateral by
66

Table of Contents
specific identification with monthly reporting. All other borrowers pledging by specific identification must provide a detailed listing of all the loans pledged to the Bank on a monthly basis.
The Bank may require certain borrowers to deliver pledged loan collateral to the Bank for one or more reasons, including the following: the borrower is a de novo institution (chartered within the last three years), an insurance company, a CDFI, or a housing associate; the Bank is concerned about the borrower’s creditworthiness; or the Bank is concerned about the maintenance of its collateral or the priority of its security interest.
As of March 31,June 30, 2021, of the loan collateral pledged to the Bank, 16% was pledged by 2423 institutions by specific identification, 54%55% was pledged by 117 institutions under a blanket lien with detailed reporting, and 30%29% was pledged by 130 institutions under a blanket lien with summary reporting. For each borrower that pledges loan collateral, the Bank conducts loan collateral field reviews once every six months or every one, two, or three years, depending on the risk profile of the borrower and the types of collateral pledged by the borrower.
As of March 31,June 30, 2021, the Bank’s maximum borrowing capacities as a percentage of the assigned market value of mortgage loan collateral pledged under a blanket lien with detailed reporting were as follows: 85% for first lien residential mortgage loans, 81% for multifamily mortgage loans, 81% for commercial mortgage loans, and 70% for second lien residential mortgage loans. The maximum borrowing capacity for small business, small agribusiness, and small farm loans was 50% of the unpaid principal balance, although most of these loans are pledged under blanket lien with summary reporting, with a maximum borrowing capacity of 25%. The highest borrowing capacities are available to borrowers that pledge under a blanket lien with detailed reporting because the detailed loan information allows the Bank to assess the value of the collateral more precisely and because additional collateral is pledged under the blanket lien that may not receive borrowing capacity but may be liquidated to repay advances in the event of default. The Bank may review and change the maximum borrowing capacity for any type of loan collateral at any time.

The Bank holds a security interest in subprime residential mortgage loans pledged as collateral. Subprime loans are defined as loans with a borrower FICO score of 660 or less at origination, or if the original FICO score is not available, as loans with a current borrower FICO score of 660 or less. At March 31,June 30, 2021, and December 31, 2020, the unpaid principal balance of these loans totaled $5$6 billion and $5 billion, respectively. The Bank reviews and assigns borrowing capacities to subprime mortgage loans as it does for all other types of loan collateral, taking into account the known credit attributes in the pricing of the loans. All advances, including those made to borrowers
67

Table of Contents
pledging subprime mortgage loans, are required to be fully collateralized. The Bank limits the amount of borrowing capacity that may be supported by subprime collateral.

Investments. The Bank has adopted credit policies and exposure limits for investments that promote risk limitation, diversification, and liquidity. These policies determine eligible counterparties and restrict the amounts and terms of the Bank’s investments with any given counterparty according to the Bank’s own capital position as well as the capital and creditworthiness of the counterparty.
The Bank monitors its investments for substantive changes in relevant market conditions and any declines in fair value. For securities in an unrealized loss position because of factors other than movements in interest rates, such as widening of mortgage asset spreads, the Bank considers whether it expects to recover the entire amortized cost basis of the security by comparing the expectations of the present value of the cash flows to be collected from the security with the amortized cost basis of the security. If the Bank’s expectations of the present value of the cash flows to be collected is less than the amortized cost basis, the difference is considered the credit loss.
When the fair value of an individual investment security falls below its amortized cost, the Bank evaluates whether an allowance for credit losses is necessary on the security. The Bank recognizes an allowance for credit losses when it determines that it will be unable to recover the entire amortized cost basis of the security and the fair value of the investment security is less than its amortized cost. The Bank considers its intent to hold the security and whether it is more likely than not that the Bank will be required to sell the security before its anticipated recovery of the remaining cost basis, and other factors. The Bank generally views changes in the fair value of the securities caused by movements in interest rates to be temporary.
The following tables present the Bank’s investment credit exposure at the dates indicated, based on the lowest of the long-term credit ratings provided by Moody’s, S&P, or Fitch Ratings (Fitch) ratings.

For all securities in its AFS and HTM portfolios, for Federal funds sold, and for securities purchased under agreements to resell, the Bank does not intend to sell any security and it is not more likely than not that the Bank will be required to sell any security before its anticipated recovery of the remaining amortized cost basis.
The Bank invests in short-term unsecured interest-bearing deposits, short-term unsecured Federal funds sold, and securities purchased under agreements to resell with member and nonmember counterparties, all of which are highly rated.
The Bank actively monitors its credit exposures and the credit quality of its counterparties, including an assessment of each counterparty’s financial performance, capital adequacy, likelihood of parental or sovereign support, and the current market perceptions of the counterparties. The Bank may also consider general macroeconomic and market conditions and political stability when establishing limits on unsecured investments with U.S. branches and agency offices of foreign commercial banks. As a result of deteriorating financial condition or concerns about adverse economic or market developments, the Bank may reduce limits or terms on unsecured investments or suspend a counterparty.
Finance Agency regulations limit the amount of unsecured credit that an individual FHLBank may extend to a single counterparty. In addition, the FHLBanks are prohibited by Finance Agency regulation from investing in financial instruments issued by non-U.S. entities other than those issued by U.S. branches and agency offices of foreign commercial banks.

Under Finance Agency regulations, the total amount of unsecured credit that an FHLBank may extend to a group of affiliated counterparties for term extensions of unsecured credit and overnight Federal funds sales, combined, may not exceed 30% of the FHLBank’s total capital. These limits on affiliated counterparty groups are in addition to the limits on extensions of unsecured credit applicable to any single counterparty within the affiliated group.

These ratings represent the lowest rating available for each unsecured investment owned by the Bank, based on the ratings provided by Fitch, Moody’s, or S&P. The Bank’s internal rating may differ from this rating.
The Bank’s MBS investments include PLRMBS, all of which were AAA-rated at the time of purchase, and agency residential MBS, which are backed by Fannie Mae, Freddie Mac, or Ginnie Mae. Some of the PLRMBS were issued by and/or purchased from members, former members, or their affiliates. The Bank has investment credit limits and terms for these investments that do not differ for members and nonmembers. Regulatory policy limits total MBS investments, including unpaid principal balance, unamortized premiums and discounts, and net charge-offs, to three times the Bank’s regulatory capital at the time of purchase. At March 31,June 30, 2021, the Bank’s MBS portfolio was 229% 218%

The Bank executes all MBS investments without preference to the status of the counterparty or the issuer of the investment as a nonmember, member, or affiliate of a member. When the Bank executes non-MBS investments with members, the Bank may give consideration to their secured credit availability and the Bank’s advances price levels.
At March 31,June 30, 2021, PLRMBS representing 12% of the amortized cost of the Bank’s MBS portfolio were labeled Alt-A by the issuer. These PLRMBS are generally collateralized by mortgage loans that are considered less risky than subprime loans but more risky than prime loans. These loans are generally made to borrowers with credit scores that are high enough to qualify for a prime mortgage loan, but the loans may not meet standard underwriting guidelines for documentation requirements, property type, or loan-to-value ratios.
As of March 31,June 30, 2021, the Bank’s investment in MBS had gross unrealized losses totaling $27$20 million, $22$10 million of which were related to PLRMBS. These gross unrealized losses were primarily due to illiquidity in the MBS market and market expectations of the credit performance of loan collateral underlying these securities, which caused these assets to be valued at discounts to their amortized cost.
For its agency MBS, the Bank expects to recover the entire amortized cost basis of these securities because the Bank determined that the strength of the issuers’ guarantees through direct obligations or support from the U.S. government is sufficient to protect the Bank from losses. As a result, the Bank determined that, as of March 31,June 30, 2021, all of the gross unrealized losses on its agency MBS are temporary.
If conditions in the housing and mortgage markets and general business and economic conditions deteriorate, the fair value of MBS may decline further, and the Bank may experience credit losses on additional PLRMBS in future periods, as well as further impairment of PLRMBS that were identified as other-than-temporarily impaired prior to January 1, 2020. Additional credit losses could adversely affect the Bank’s earnings and retained earnings and its ability to pay dividends and repurchase capital stock. The Bank cannot predict whether it will be required to record an allowance for credit losses on its PLRMBS in the future.
The Bank has exposure to investment securities with interest rates indexed to LIBOR. The following tables present the unpaid principal balance of adjustable rate investment securities by interest rate index and the unpaid principal balance of LIBOR-indexed investments for LIBOR tenors that cease or will no longer be representative immediately after June 30, 2023, by redemption term at March 31,June 30, 2021, and December 31, 2020. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Financial Condition” for more information on the LIBOR transition and on SOFR as an alternative market benchmark.

Derivative Counterparties. The Bank has adopted credit policies and exposure limits for uncleared derivatives credit exposure. Over-the-counter derivatives may be either entered into directly with a counterparty (uncleared derivatives) or executed either with an executing dealer or on a swap execution facility and then cleared through a futures commission merchant (clearing agent)or clearing agent with a derivatives clearing organization (cleared derivatives).
Uncleared Derivatives – The Bank selects only highly rated derivative dealers and major banks (derivative dealer counterparties) that meet the Bank’s eligibility criteria to act as counterparties for its uncleared derivative activities. In addition, for all uncleared derivative transactions, the Bank has entered into master netting agreements and bilateral credit support agreements with all active derivative dealer counterparties that provide for delivery of collateral at specified levels to limit the Bank’s net unsecured credit exposure to these counterparties. Under these policies and agreements, the amount of unsecured credit exposure to an individual derivative dealer counterparty is set at zero (subject to a minimum transfer amount).
The Bank is subject to the risk of potential nonperformance by the counterparties to derivative agreements. A counterparty generally must deliver collateral to the Bank if the total market value of the Bank’s exposure to that counterparty rises above a specific trigger point. Currently, all of the Bank’s active uncleared derivative counterparties have a zero threshold. As a result of these risk mitigation initiatives, the Bank does not anticipate any credit losses on its uncleared derivative transactions with counterparties as of March 31,June 30, 2021.
Cleared Derivatives – In a cleared derivatives transaction, the Bank is subject to nonperformance by the clearinghouse and its futures commission merchant or clearing agent. The requirement that the Bank post initial and variation margin through a clearing agent to the clearinghouse exposes the Bank to institutional credit risk if the clearing agent fails to meet its obligations. The use of a clearinghouse, or central counterparty, lowers overall credit risk exposure because it employs standard valuation and initial and variation margin processes and is specifically designed to withstand remote but plausible counterparty default credit events. Variation margin is posted or collected for changes in the value of the portfolio, and initial margin is posted for changes in risk profile of the portfolio. Because of an increase in market values of cleared derivatives during the first quartersix months of 2021, there was an increase in variation margin collected on cleared derivatives that resulted in an increase in net cash provided by operating activities reported on the Statements of Cash Flows. Because of a decline in market values of cleared derivatives during the first quartersix months of 2020, there was an increase in variation margin posted on cleared derivatives that resulted in an increase in net cash used in operating activities reported on the Statements of Cash Flows. The Bank does not anticipate any credit losses on its cleared derivatives as of March 31,June 30, 2021. The increase or decrease in the credit exposure net of cash variation margin, from one period to the next, may be affected by changes in several variables, such as the size, composition, market value, and accrued interest of the portfolio.
The following tables present the Bank’s credit exposure to its derivative dealer counterparties at the dates indicated.

Critical Accounting Policies and Estimates
The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP) requires management to make a number of judgments, estimates, and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities, if applicable, and the reported amounts of income, expenses, gains, and losses during the reporting period. Changes in these judgments, estimates, and assumptions could potentially affect the Bank’s financial position and results of
7582

Table of Contents
operations significantly. Although the Bank believes these judgments, estimates, and assumptions to be reasonably accurate, actual results may differ.
In the Bank’s 2020 Form 10-K, the following accounting policies and estimates were identified as critical because they require the Bank to make subjective or complex judgments about matters that are inherently uncertain and because of the likelihood that materially different amounts would be reported under different conditions or using different assumptions. These policies and estimates are: accounting for derivatives; estimating fair values of investments classified as trading and AFS, derivatives and associated hedged items carried at fair value in accordance with the accounting for derivative instruments and associated hedging activities, and financial instruments carried at fair value under the fair value option; and estimating the prepayment speeds on MBS and mortgage loans for the accounting of amortization of premiums and accretion of discounts and credit losses previously recorded prior to the adoption of accounting guidance related to the measurement of credit losses on MBS and mortgage loans.
There have been no significant changes in the judgments and assumptions made during the first threesix months of 2021 in applying the Bank’s critical accounting policies. These policies and the judgments, estimates, and assumptions are also described in “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations – Critical Accounting Policies and Estimates” and “Item 8. Financial Statements and Supplementary Data – Note 1 – Summary of Significant Accounting Policies” in the Bank’s 2020 Form 10-K and in “Item 1. Financial Statements – Note 12 – Fair Value.”

Recently Issued Accounting Guidance and Interpretations
See “Item 1. Financial Statements – Note 2 – Recently Issued Accounting Guidance” for a discussion of recently issued accounting standards and interpretations.

Recent Developments
There are no recent developments for the firstsecond quarter of 2021 that are expected to have a material effect on the financial condition or results of operations or that are otherwise material to the Bank.

In accordance with regulations governing the operations of the FHLBanks, each FHLBank, including the Bank, is jointly and severally liable for the FHLBank System’s consolidated obligations issued under Section 11(a) of the FHLBank Act, and in accordance with the FHLBank Act, each FHLBank, including the Bank, is jointly and severally liable for consolidated obligations issued under Section 11(c) of the FHLBank Act. The joint and several liability regulation authorizes the Finance Agency to require any FHLBank to repay all or a portion of the principal or interest on consolidated obligations for which another FHLBank is the primary obligor.
The par value of the outstanding consolidated obligations of the FHLBanks was $696.4$666.7 billion at March 31,June 30, 2021, and $746.7 billion at December 31, 2020. The par value of the Bank’s participation in consolidated obligations was $50.2$46.5 billion at March 31,June 30, 2021, and $60.6 billion at December 31, 2020. The Bank had committed to the issuance of $555$130 million in consolidated obligations at March 31,June 30, 2021. The Bank had no commitments to issue consolidated obligations at December 31, 2020.
In addition, in the ordinary course of business, the Bank engages in financial transactions that, in accordance with U.S. GAAP, are not recorded on the Bank’s Statements of Condition or may be recorded on the Bank’s Statements of Condition in amounts that are different from the full contract or notional amount of the transactions. For example, the Bank routinely enters into commitments to extend advances and issues standby letters of credit. These commitments and standby letters of credit may represent future cash requirements of the Bank, although the standby letters of credit usually expire without being drawn upon. Standby letters of credit are subject to the same

underwriting and collateral requirements as advances made by the Bank. At March 31,June 30, 2021, the Bank had no advance commitments and $17.1$15.9 billion in standby letters of credit outstanding. At December 31, 2020, the Bank had no advance commitments and $19.4 billion in standby letters of credit outstanding.

ITEM 3.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market risk is defined as the risk to the Bank’s market value of capital and future earnings (excluding the impact of any cumulative net gains or losses on derivatives and associated hedged items and on financial instruments carried at fair value) as a result of movements in market interest rates, interest rate spreads, interest rate volatility, and other market factors (market rate factors). This profile reflects the Bank’s objective of maintaining a conservative asset-liability mix and its commitment to providing value to its members through products and dividends without subjecting their investments in Bank capital stock to significant market risk.
The Bank’s Risk Management Policy includes a market risk management objective aimed at maintaining a relatively low adverse exposure of the market value of capital and future earnings (excluding the impact of any cumulative net gains or losses on derivatives and associated hedged items and on financial instruments carried at fair value) to changes in market rate factors. See “Total Bank Market Risk” below.
Market risk identification and measurement are primarily accomplished through market value of capital sensitivity analyses and projected earnings and adjusted return on capital sensitivity analyses. The Risk Management Policy approved by the Bank’s board of directors establishes market risk policy limits and market risk measurement standards at the total Bank level as well as at the business segment level. Additional guidelines approved by the Bank’s Enterprise Risk Committee apply to the Bank’s two business segments, the advances-related business and the mortgage-related business. These guidelines provide limits that are monitored at the segment level and are consistent with the Bank’s policy limits. Market risk is managed for each business segment on a daily basis, as discussed below in “Segment Market Risk.” Compliance with Bank policies and guidelines is reviewed by the Bank’s board of directors on a regular basis, along with a corrective action plan if applicable.
Total Bank Market Risk
Market Value of Capital Sensitivity – The Bank uses market value of capital sensitivity (the interest rate sensitivity of the net fair value of all assets, liabilities, and interest rate exchange agreements) as an important measure of the Bank’s exposure to changes in interest rates.
The Bank’s market value of capital sensitivity policy limits the potential adverse impact of an instantaneous parallel shift of a plus or minus 100-basis-point change in interest rates from current rates (base case) to no worse than 3.0% of the estimated market value of capital. In addition, the policy limits the potential adverse impact of an instantaneous plus or minus 100-basis-point change in interest rates measured from interest rates that are 200 basis points above or below the base case to no worse than 4.0% of the estimated market value of capital. In the case where a market risk sensitivity compliance metric cannot be estimated with a parallel shift in interest rates because of prevailing low interest rates, the sensitivity metric is not reported. The Bank’s measured market value of capital sensitivity was within the policy limits as of March 31,June 30, 2021.
To determine the Bank’s estimated risk sensitivities to interest rates for the market value of capital sensitivity, the Bank uses a third-party proprietary asset and liability system to calculate estimated market values under alternative interest rate scenarios. The system analyzes all of the Bank’s financial instruments, including derivatives, on a transaction-level basis using sophisticated valuation models with consistent and appropriate behavioral assumptions and current position data. The system also includes a third-party mortgage prepayment model.
At least annually, the Bank reexamines the major assumptions and methodologies used in the model, including interest rate curves, spreads for discounting, and mortgage prepayment assumptions. The Bank also compares the
7784

Table of Contents
mortgage prepayment assumptions in the third-party model to other sources, including actual mortgage prepayment history.
The following table presents the sensitivity of the market value of capital (the market value of all of the Bank’s assets, liabilities, and associated interest rate exchange agreements, with mortgage assets valued using market spreads implied by current market prices) to changes in interest rates. The table presents the estimated percentage change in the Bank’s market value of capital that would be expected to result from changes in interest rates under different interest rate scenarios, using market spread assumptions.

The Bank’s estimates of the sensitivity of the market value of capital to changes in interest rates as of March 31,June 30, 2021, are comparable with the estimates as of December 31, 2020, with the exception of the declining 100 basis-point rate scenario. The increase in intermediate and long-term interest rates in the first quarter of 2021 resulted in a larger absolute down 100 basis-point rate shock relative to yearend. Interest rates continue to remain at historically low levels, ranging from 0.44 basis points for the one-month Treasury bill to 174144 basis points for the ten-year Treasury note.
The Bank’s Risk Management Policy provides guidelines for the payment of dividends and the repurchase of excess capital stock based on the ratio of the Bank’s estimated market value of total capital to par value of capital stock. If this ratio at the end of any quarter is: (i) less than 100% but greater than or equal to 90%, any dividend would be limited to an annualized rate no greater than the daily average of the Federal funds effective rate for the applicable quarter (subject to certain conditions), and any excess capital stock repurchases would not exceed $500 million (subject to certain conditions); (ii) less than 90% but greater than or equal to 70%, any dividend and any excess capital stock repurchases would be subject to the same limitations and conditions as in (i) above, except that any excess capital stock repurchases would not exceed 4% of the Bank’s outstanding capital stock as of the repurchase date; and (iii) less than 70%, the Bank would not pay a dividend, not repurchase excess capital stock (but continue to redeem excess capital stock as provided in the Bank’s capital plan), limit the acquisition of certain assets, and review the Bank’s risk policies. A decision by the board of directors to declare or not declare any dividend or repurchase any excess capital stock is a discretionary matter and is subject to the requirements and restrictions of the FHLBank Act and applicable requirements under the regulations governing the operations of the FHLBanks. The ratio of the Bank’s estimated market value of total capital to par value of capital stock was 295%293% as of March 31,June 30, 2021.
Adjusted Return on Capital – The adjusted return on capital is a measure used by the Bank to assess financial performance. The adjusted return on capital is based on current period economic earnings that exclude the effects of unrealized net gains or losses resulting from the Bank’s derivatives and associated hedged items and from financial instruments carried at fair value, which will generally reverse through changes in future valuations and settlements of contractual interest cash flows over the remaining contractual terms to maturity or by the call or put date of the assets and liabilities held under the fair value option, hedged assets and liabilities, and derivatives. Economic earnings also exclude the interest expense on mandatorily redeemable capital stock and the 20% of net income allocated to the Bank’s restricted retained earnings account in accordance with the FHLBanks’ Joint Capital Enhancement (JCE) Agreement. Economic earnings exclude these amounts in order to more accurately reflect the
7885

Table of Contents
amount of earnings that may be available to be paid as dividends to shareholders. With the decline in consolidated obligations outstanding in 2020, the Bank ceased contributions to restricted retained earnings in the fourth quarter of 2020, in accordance with the JCE Agreement; and no further allocations of net income into restricted retained earnings are required until such time as the allocation requirement exceeds the balance of restricted retained earnings. Additionally, the JCE Agreement provides that amounts in restricted retained earnings in excess of 150% of the Bank’s restricted retained earnings minimum (i.e., 1% of the Bank’s total consolidated obligations calculated as of the last day of each calendar quarter) may be released from restricted retained earnings. As of June 30, 2021, the amount in restricted retained earnings was 152% of the Bank’s restricted retained earnings minimum.
The Bank limits the sensitivity of projected financial performance through a board of directorsdirectors’ policy limit on projected adverse changes in the adjusted return on capital. The Bank’s adjusted return on capital sensitivity policy limits the potential adverse impact of an instantaneous parallel shift of a plus or minus 200-basis-point change in interest rates from current rates (base case) to no worse than –120 basis points from the base case projected adjusted return on capital. Given the current low interest rate environment, in the downward shift interest rates were limited to non-negative rates. With the indicated interest rate shifts, the adjusted return on capital for the projected 12-month horizon would be expected to decrease by 520 basis points in the –200 basis-points scenario, well within the policy limit of –120 basis points.
Duration Gap – Duration gap is the difference between the estimated durations (market value sensitivity) of assets and liabilities (including the impact of interest rate exchange agreements) and reflects the extent to which estimated maturity and repricing cash flows for assets and liabilities are matched. The Bank monitors duration gap analysis at the total Bank level and does not have a policy limit.

Segment Market Risk. The financial performance and interest rate risks of each business segment are managed within prescribed guidelines and policy limits.
Advances-Related Business – Interest rate risk arises from the advances-related business primarily through the use of shareholder-contributed capital and retained earnings to fund fixed rate investments of targeted amounts and maturities. In general, advances result in very little net interest rate risk for the Bank because most fixed rate advances with original maturities greater than three months and all advances with embedded options are simultaneously hedged with an interest rate swap or option with terms to offset the advance. The interest rate swap or option generally is maintained as a hedge for the life of the advance. These hedged advances effectively create a pool of variable rate assets, which, in combination with the strategy of raising debt swapped to variable rate liabilities, creates an advances portfolio with low net interest rate risk.
Money market investments used for liquidity management generally have maturities of one month or less. In addition, to increase the Bank’s liquidity position, the Bank invests in Treasury securities, generally with terms of less than three years. These fixed rate investments are swapped to variable rate investments.
The interest rate risk in the advances-related business is primarily associated with the Bank’s strategy for investing capital (capital stock, including mandatorily redeemable capital stock, and retained earnings). The Bank’s strategy is generally to invest 50% of capital in short-term investments (maturities of three months or less) and 50% in intermediate-term investments (a laddered portfolio of investments with maturities of up to four years). However,
86

Table of Contents
this strategy may be altered from time to time depending on market conditions. The strategy to invest 50% of capital in short-term assets is intended to mitigate the market value of capital risks associated with the potential repurchase or redemption of excess capital stock. Excess capital stock usually results from a decline in a borrower’s
79

Table of Contents
outstanding advances or by a membership termination. Under the Bank’s capital plan, capital stock, when repurchased or redeemed, is required to be repurchased or redeemed at its par value of $100 per share, subject to certain regulatory and statutory limits. The strategy to invest 50% of capital in a laddered portfolio of investments with short to intermediate maturities is intended to take advantage of the higher earnings available from a generally positively sloped yield curve, when intermediate-term investments generally have higher yields than short-term investments.
The Bank updates the repricing and maturity gaps for actual asset, liability, and derivative transactions that occur in the advances-related segment each day. The Bank regularly compares the targeted repricing and maturity gaps to the actual repricing and maturity gaps to identify rebalancing needs for the targeted gaps. On a weekly basis, the Bank evaluates the projected impact of expected maturities and scheduled repricings of assets, liabilities, and interest rate exchange agreements on the interest rate risk of the advances-related segment. These analyses are used to measure and manage potential reinvestment risk (when the remaining term of advances is shorter than the remaining term of the financing) and potential refinancing risk (when the remaining term of advances is longer than the remaining term of the financing).
Because of the short-term and variable rate nature of the assets, liabilities, and derivatives of the advances-related business, the Bank’s interest rate risk guidelines address the amounts of net assets that are expected to mature or reprice in a given period. The market value sensitivity analyses and net interest income simulations are also used to identify and measure risk and variances to the target interest rate risk exposure in the advances-related segment.
Mortgage-Related Business – The Bank’s mortgage assets include MBS, most of which are classified as HTM or AFS, with a small amount classified as trading, and mortgage loans held for portfolio purchased under the MPF Program. The Bank is exposed to interest rate risk from the mortgage-related business because the principal cash flows of the mortgage assets and the liabilities that fund them are not exactly matched through time and across all possible interest rate scenarios, given the effect of mortgage prepayments and the existence of interest rate caps on certain adjustable rate MBS.
The Bank manages the interest rate risk and market risk of the mortgage-related segment through its investment in low risk assets and selected funding and hedging strategies. The total carrying value of MBS and mortgage loans at March 31,June 30, 2021, was $16.2$15.6 billion, including $14.6$14.3 billion in MBS and $1.6$1.3 billion in mortgage loans. The total carrying value of MBS and mortgage loans at December 31, 2020, was $17.7 billion, including $15.8 billion in MBS and $1.9 billion in mortgage loans. Floating rate securities, and fixed rate multifamily securities that have been converted to floating rate through the use of interest rate swaps, were $13.3$13.2 billion, or 82%85%, of MBS and mortgage loans at March 31,June 30, 2021, and $14.2 billion, or 80%, of MBS and mortgage loans at December 31, 2020. Intermediate and long-term fixed rate assets, whose interest rate and market risks have been partially offset through the use of fixed rate callable debt, fixed rate non-callable debt, and certain interest rate swaps, were $2.9$2.4 billion, or 18%15%, of MBS and mortgage loans, at March 31,June 30, 2021, and $3.5 billion, or 20%, of MBS and mortgage loans at December 31, 2020.
The estimated market risk of the mortgage-related business is managed both at the time an asset is purchased and on an ongoing basis for the total portfolio. At the time of purchase (for all significant mortgage asset acquisitions), the Bank analyzes the estimated earnings sensitivity and estimated market value sensitivity, taking into consideration the estimated mortgage prepayment sensitivity of the mortgage assets and anticipated funding and hedging activities under various interest rate scenarios. The related funding and hedging transactions are executed at or close to the time of purchase of a mortgage asset.
At least monthly, the Bank reviews the estimated market risk profile of the entire portfolio of mortgage assets and related funding and hedging transactions. The Bank then considers rebalancing strategies to modify the estimated mortgage portfolio market risk profile. Periodically, the Bank performs more in-depth analyses, which include an analysis of the impacts of non-parallel shifts in the yield curve and assessments of the impacts of unanticipated
87

Table of Contents
mortgage prepayment behavior. Based on these analyses, the Bank may take actions to rebalance the mortgage portfolio’s market risk profile. These rebalancing strategies may include entering into new funding and hedging
80

Table of Contents
transactions, forgoing or modifying certain funding or hedging transactions normally executed with new mortgage purchases, or terminating certain funding and hedging transactions for the mortgage asset portfolio.
The Bank manages the estimated interest rate risk associated with mortgage assets, including mortgage prepayment risk, through a combination of debt issuance and derivatives. The Bank may obtain funding through callable and non-callable FHLBank System debt and may execute derivative transactions to achieve principal cash flow patterns and market value sensitivities for the liabilities and derivatives that provide a significant offset to the interest rate and mortgage prepayment risks associated with the mortgage assets. Debt issued to finance mortgage assets may be fixed rate debt, callable fixed rate debt, adjustable rate debt, or callable adjustable rate debt. Derivatives may be used as temporary hedges of anticipated debt issuance or long-term hedges of debt used to finance the mortgage assets. The derivatives used to hedge the interest rate risk of fixed rate mortgage assets generally may be callable and non-callable pay-fixed interest rate swaps. Derivatives may also be used to offset the interest rate cap risk embedded in adjustable rate MBS.
As discussed above in “Total Bank Market Risk Market Value of Capital Sensitivity,” the Bank uses market value of capital sensitivity as a primary market value metric for measuring the Bank’s exposure to interest rates. The Bank’s interest rate risk policies and guidelines for the mortgage-related business address the market value of capital sensitivity of the assets, liabilities, and derivatives of the mortgage-related business.

ITEM 4.    CONTROLS AND PROCEDURES
Disclosure Controls and Procedures
The senior management of the Federal Home Loan Bank of San Francisco (Bank) is responsible for establishing and maintaining a system of disclosure controls and procedures designed to ensure that information required to be disclosed by the Bank in the reports filed or submitted under the Securities Exchange Act of 1934 (1934 Act) is recorded, processed, summarized, and reported within the time periods specified in the rules and forms of the Securities and Exchange Commission. The Bank’s disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by the Bank in the reports that it files or submits under the 1934 Act is accumulated and communicated to the Bank’s management, including its principal executive officer or officers and principal financial officer or officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. In designing and evaluating the Bank’s disclosure controls and procedures, the Bank’s management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and the Bank’s management necessarily is required to apply its judgment in evaluating the cost-benefit relationship of controls and procedures.
Management of the Bank has evaluated the effectiveness of the design and operation of its disclosure controls and procedures with the participation of the president and chief executive officer and executive vice president and chief financial officer as of the end of the period covered by this report. Based on that evaluation, the Bank’s president and chief executive officer and executive vice president and chief financial officer have concluded that the Bank’s disclosure controls and procedures were effective at a reasonable assurance level as of the end of the period covered by this report.
Internal Control Over Financial Reporting
During the three months ended March 31,June 30, 2021, there were no changes in the Bank’s internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, the Bank’s internal control over financial reporting.
Consolidated Obligations
The Bank’s disclosure controls and procedures include controls and procedures for accumulating and communicating information in compliance with the Bank’s disclosure and financial reporting requirements relating to the joint and several liability for the consolidated obligations of the Federal Home Loan Banks (FHLBanks). Because the FHLBanks are independently managed and operated, the Bank’s management relies on information that is provided or disseminated by the Federal Housing Finance Agency (Finance Agency), the Office of Finance, and the other FHLBanks, as well as on published FHLBank credit ratings, in determining whether the joint and several liability regulation is reasonably likely to result in a direct obligation for the Bank or whether it is reasonably possible that the Bank will accrue a direct liability.
The Bank’s management also relies on the operation of the joint and several liability regulation. The joint and several liability regulation requires that each FHLBank file with the Finance Agency a quarterly certification that it will remain capable of making full and timely payment of all of its current obligations, including direct obligations, coming due during the next quarter. In addition, if an FHLBank cannot make such a certification or if it projects that it may be unable to meet its current obligations during the next quarter on a timely basis, it must file a notice with the Finance Agency. Under the joint and several liability regulation, the Finance Agency may order any FHLBank to make principal and interest payments on any consolidated obligations of any other FHLBank, or allocate the outstanding liability of an FHLBank among all remaining FHLBanks on a pro rata basis in proportion to each FHLBank’s participation in all consolidated obligations outstanding or on any other basis.
