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 normal 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, ~~2017.~~2018. 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, ~~2016 (2016~~2017 (2017 Form

~~10-K)~~ 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 the allowance for credit losses on the advances and mortgage loan portfolios; accounting for derivatives; estimating fair values of investments classified as trading and available-for-sale, 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 accounting for other-than-temporary impairment (OTTI) for investment securities; and estimating the prepayment speeds on mortgage-backed securities (MBS) and mortgage loans for the accounting of amortization of premiums and accretion of discounts on MBS and mortgage loans. Actual results could differ significantly from these estimates.

Financial Instruments Meeting Netting Requirements. The Bank presents certain financial instruments, including derivative instruments and securities purchased under agreements to resell, on a net basis when they have a legal right of offset and all other requirements for netting are met (collectively referred to as the netting requirements). The Bank has elected to offset its derivative asset and liability positions, as well as cash collateral received or pledged, when the netting requirements are met. The Bank did not have any offsetting liabilities related to its securities purchased under agreements to resell for the periods presented.

The net exposure for these financial instruments can change on a daily basis; therefore, there may be a delay between the time this exposure change is identified and additional collateral is requested, and the time this collateral is received or pledged. Likewise, there may be a delay for excess collateral to be returned. For derivative instruments that meet the netting requirements, any excess cash collateral received or pledged is recognized as a derivative liability or derivative asset. Additional information regarding these agreements is provided in Note 15 – Derivatives and Hedging Activities. Based on the fair value of the related collateral held, the securities purchased under agreements to resell were fully collateralized for the periods presented.

Derivatives. All derivatives are recognized on the Statements of Condition at their fair values and are reported as either derivative assets or derivative liabilities, net of cash collateral, including initial and certain variation margin, and accrued interest received from or pledged to clearing agents and/or counterparties. The fair values of derivatives are netted by clearing agent and/or counterparty when the netting requirements have been met. If these netted amounts are positive, they are classified as an asset, and if negative, they are classified as a liability. Cash flows associated with derivatives are reflected as cash flows from operating activities on the Statements of Cash Flows unless the derivative meets the criteria to be a financing derivative.

The Bank uses the clearinghouse, London Clearing House (LCH) Ltd, for all cleared derivative transactions. Effective January 16, 2018, LCH Ltd made certain amendments to its rulebook, changing the legal characterization

of variation margin payments to be daily settlement payments, rather than collateral. Initial margin continues to be considered cash collateral.

Variable Interest Entities. The Bank’s investments in variable interest entities (VIEs) are limited to private-label residential mortgage-backed securities (PLRMBS). On an ongoing basis, the Bank performs a quarterly evaluation

to determine whether it is the primary beneficiary in any VIE. The Bank evaluated its investments in VIEs as of ~~September~~June 30, ~~2017,~~2018, to determine whether it is a primary beneficiary of any of these investments. The primary beneficiary is required to consolidate a VIE. The Bank determined that consolidation accounting is not required because the Bank is not the primary beneficiary of these VIEs for the periods presented. The Bank does not have the power to significantly affect the economic performance of any of these investments because it does not act as a key decision maker nor does it have the unilateral ability to replace a key decision maker. In addition, the Bank does not design, sponsor, transfer, service, or provide credit or liquidity support in any of its investments in VIEs. The Bank’s maximum loss exposure for these investments is limited to the carrying value.

Note 2 — Recently Issued and Adopted Accounting Guidance

Targeted Improvements to Accounting for Hedging Activities. On August 28, 2017, the Financial Accounting Standards Board (FASB) issued amended guidance to improve the financial reporting of hedging relationships to better portray the economic results of an entity’s risk management activities in its financial statements. This guidance requires that, for fair value hedges, the entire change in the fair value of the hedging instrument included in the assessment of hedge effectiveness be presented in the same income statement line that is used to present the earnings effect of the hedged item. For cash flow hedges, the entire change in the fair value of the hedging instrument included in the assessment of hedge effectiveness must be recorded in other comprehensive income. In addition, the amendments include certain targeted improvements to the assessment of hedge effectiveness and permit, among other things, the following:

Measurement of the change in fair value of the hedged item on the basis of the benchmark rate component of the contractual coupon cash flows determined at hedge inception.

Measurement of the hedged item in a partial-term fair value hedge of interest rate risk by assuming the hedged item has a term that reflects only the designated cash flows being hedged.

Consideration only of how changes in the benchmark interest rate affect a decision to settle a prepayable instrument before its scheduled maturity in calculating the change in the fair value of the hedged item attributable to interest rate risk.

For a cash flow hedge of interest rate risk of a variable-rate financial instrument, an entity could designate as the hedged risk the variability in cash flows attributable to the contractually specified interest rate.

This guidance becomes effective for the Bank for interim and annual periods beginning on January 1, 2019, and early adoption is permitted. The amended presentation and disclosure guidance is required only prospectively. The Bank does not intend to adopt this guidance early. The Bank is in the process of evaluating this guidance, and its effect on the Bank’s financial condition, results of operations, cash flows, and financial statement disclosures has not yet been determined.

Premium Amortization on Purchased Callable Debt Securities. On March 30, 2017, the FASB issued amended guidance to shorten the amortization period for certain purchased callable debt securities held at a premium. Specifically, the amendments require the premium to be amortized to the earliest call date. The amendments do not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. This guidance affects all entities that hold investments in callable debt securities that have an amortized cost basis in excess of the amount that is repayable by the issuer at the earliest call date (that is, at a premium). This guidance is

effective for the Bank for interim and annual periods beginning on January 1, 2019, and early adoption is permitted. This guidance should be applied using a modified retrospective method through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. The adoption of this guidance is not expected to have any effect on the Bank’s financial condition, results of operations, or cash flows.

Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. On March 10, 2017, the FASB issued amended guidance to improve the presentation of net periodic pension cost and net periodic postretirement benefit cost. The amendments require that employer disaggregate the service cost component from the other components of net benefit cost. The amendments also provide explicit guidance on how to present the service cost component and the other components of net benefit cost in the Statements of ~~Income and allow only the service cost component of net benefit cost to be eligible for capitalization.~~Income.

The adoption of this guidance isdid not ~~expected to~~ have a material effect on the Bank’s financial condition, results of operations, cash flows, ~~and~~or financial statement disclosures.

Classification of Certain Cash Receipts and Cash Payments. On August 26, 2016, the FASB issued amendments to clarify guidance on the classification of certain cash receipts and payments in the Statements of Cash Flows. This guidance is intended to reduce existing diversity in practice in how certain cash receipts and cash payments are presented and classified on the Statements of Cash Flows. This guidance isbecame effective for the Bank for interim and annual periods beginning on January 1, ~~2018, and early adoption is permitted. The guidance should be applied using a retrospective transition method to each period presented. The Bank does not intend to adopt this guidance early.~~2018. The adoption of this guidance isdid not ~~expected to~~ have any effect on the Bank’s financial condition, results of operations, or cash flows.

Measurement of Credit Losses on Financial Instruments. On June 16, 2016, the FASB issued amended guidance for the accounting for credit losses on financial instruments. The amendments require entities to measure expected credit losses based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. An entity must use judgment in determining the relevant information and estimation methods that are appropriate under the circumstances. In addition, under the new guidance, a financial asset, or a group of financial assets, is required to be measured at its amortized cost to be presented at the net amount expected to be collected over the contractual term of the financial assets. Among other things, the guidance also requires:

The Statement of Income to reflect the measurement of credit losses for newly recognized financial assets, as well as the expected increases or decreases of expected credit losses that have taken place during the period.

The entities to determine the allowance for credit losses for purchased financial assets with a more-than-insignificant amount of credit deterioration since origination that are measured at amortized cost basis in a similar manner to other financial assets measured at amortized cost basis. The initial allowance for credit losses is required to be added to the purchase price.

Credit losses relating to available-for-sale debt securities to be recorded through an allowance for credit losses. The amendments limit the allowance for credit losses to the amount by which fair value is below amortized cost.

Public entities to further disaggregate the current disclosure of credit quality indicators in relation to the amortized cost of financing receivables by the year of origination (i.e., vintage).

The guidance is effective for the Bank for interim and annual periods beginning on January 1, 2020. Early application is permitted as of the interim and annual reporting periods beginning after December 15, 2018. The guidance should be applied using a modified-retrospective approach, through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. In addition, the entities are required to use a prospective transition approach for purchased financial assets with a more-than-insignificant amount of credit deterioration since origination and for debt securities for which an other-than-temporary impairment had been recognized before the effective date. The Bank does not intend to adopt the guidance early. The Bank is in the process of evaluating this guidance and expects the adoption of the guidance may

result in an increase in the allowance for credit losses given the requirement to assess losses for the entire estimated life of the financial asset, including an allowance for debt securities. The effect on the Bank’s financial condition, results of operations, and cash flows will depend on the composition of financial assets held by the Bank at the adoption date, as well as on economic conditions and forecasts at that time.

~~Contingent Put and Call Options in Debt Instruments.~~ On March 14, 2016, the FASB issued amendments to clarify the requirements for assessing whether contingent call (put) options that can accelerate the payment of principal on debt instruments are clearly and closely related to their debt hosts. The guidance requires entities to apply only the four-step decision sequence when assessing whether the economic characteristics and risks of call

~~Table of Contents~~

~~Federal Home Loan Bank of San Francisco~~

~~Notes to Financial Statements (continued)~~

(put) options are clearly and closely related to the economic characteristics and risks of their debt hosts. Consequently, when a call (put) option is contingently exercisable, an entity does not have to assess whether the event that triggers the ability to exercise a call (put) option is related to interest rates or credit risks. This guidance became effective for the Bank for the interim and annual periods beginning on January 1, 2017. The adoption of this guidance had no effect on the Bank’s financial condition, results of operations, and cash flows.

~~Effect of Derivative Contract Novations on Existing Hedge Accounting Relationships.~~ On March 10, 2016, the FASB issued amendments to clarify that a change in the counterparty to a derivative instrument that has been designated as the hedging instrument under U.S. GAAP does not, in and of itself, require dedesignation of that hedging relationship provided that all other hedge accounting criteria continue to be met. This guidance became effective for the Bank for the interim and annual periods beginning on January 1, 2017, and early adoption was permitted. The amendments provide entities with the option to apply the guidance using either a prospective approach or a modified retrospective approach, retrospectively applied to all derivative instruments that meet the specific conditions. The Bank elected to early adopt the guidance prospectively on January 1, 2016. The adoption of this guidance had no effect on the Bank’s financial condition, results of operations, and cash flows.

Recognition of Lease Assets and Lease Liabilities. On February 25, 2016, the FASB issued guidance that requires recognition of lease assets and lease liabilities on the Statements of Condition and disclosure of key information about leasing arrangements. In particular, this guidance requires a lessee of operating or finance leases to recognize on the Statements of Condition a liability to make lease payments and a right-of-use asset representing its right to use the underlying asset for the lease term. However, for leases with a term of 12 months or less, a lessee is permitted to make an accounting policy election not to recognize lease assets and lease liabilities. Under previous U.S. GAAP, a lessee was not required to recognize lease assets and lease liabilities arising from operating leases on the Statements of Condition. While this guidance does not fundamentally change lessor accounting, some changes have been made to align that guidance with the lessee guidance and other areas within U.S. GAAP.

The guidance becomes effective for the Bank for the interim and annual periods beginning on January 1, 2019, and early application is permitted. The guidance requires lessors and lessees to recognize and measure leases at the beginning of the earliest period presented in the financial statements using a modified retrospective approach. The Bank does not intend to adopt this guidance early. Upon adoption, the Bank expects to report higher assets and liabilities as a result of recording right-of-use assets and lease liabilities for its existing leases on the Statements of Condition. The Bank is in the process of evaluating this guidance, but its effect on the Bank’s financial condition, results of operations, and cash flows is not expected to be material.

Recognition and Measurement of Financial Assets and Financial Liabilities. On January 5, 2016, the FASB issued amended guidance on certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. This guidance includes, but is not limited to, the following:

Requires equity investments (with certain exceptions) to be measured at fair value with changes in fair value recognized in net income;

Requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments;

Requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset on the Statement of Condition or in the accompanying notes to the financial statements;

Eliminates the requirement for public entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the Statement of Condition.

The guidance ~~becomes~~became effective for the Bank for the interim and annual periods beginning on January 1, ~~2018, and early adoption is only permitted for certain provisions. The amendments, in general, should be applied by means of~~

However,~~disclosures, the requirement to present the instrument-specific credit risk in other comprehensive income isdid not ~~expected to~~ have any effect on the Bank’s financial condition, results of operations, ~~and~~or cash flows.

Revenue from Contracts with Customers. On May 28, 2014, the FASB issued ~~its~~ guidance on revenue from contracts with customers. This guidance outlines a comprehensive model for recognizing revenue arising from contracts with customers and supersedes most current revenue recognition guidance. In addition, this guidance amends the existing requirements for the recognition of a gain or loss on the transfer of non-financial assets that are not in a contract with a customer. This guidance applies to all contracts with customers except those that are within the scope of certain other standards, such as financial instruments, certain guarantees, insurance contracts, and lease contracts.

~~The~~ This guidance provides entities with the option of using either of the following adoption methods: a full retrospective method, applied retrospectively to each prior reporting period presented; or a modified retrospective method, with the cumulative effect of retrospectively applying this guidance recognized at the date of initial application.

On August 12, 2015, the FASB issued an amendment to defer the effective date of the guidance issued in May 2014 by one year. In 2016, the FASB issued additional amendments to clarify certain aspects of the new revenue guidance. However, the amendments do not change the core principle in the new revenue standard. The guidance isbecame effective for the Bank for the interim and annual periods beginning on January 1, 2018. ~~Early application is permitted only as of the interim and annual reporting periods beginning after December 15, 2016. The Bank does not intend to adopt this guidance early.~~ Given that the majority of the ~~Bank’s~~Bank's financial instruments and other contractual rights that generate revenue are covered by other ~~accounting guidance under~~ U.S. GAAP, the ~~effect~~adoption of this guidance did not have any effect on the ~~Bank’s~~Bank's financial condition, results of operations, ~~and~~or cash ~~flows is not expected to be material.~~flows.

(1)	Amortized cost includes unpaid principal balance, unamortized premiums and discounts, and previous OTTI recognized in earnings. The carrying value of HTM securities represents amortized cost after adjustment for non-credit-related OTTI recognized in AOCI.

At ~~September~~June 30, ~~2017,~~2018, the amortized cost of the Bank’s MBS classified as HTM included premiums of ~~$20,~~$16, discounts of ~~$25,~~$21, and credit-related OTTI of $7. At December 31, ~~2016~~2017, the amortized cost of the Bank’s MBS classified as HTM included premiums of $2919, discounts of $3424, and credit-related OTTI of $87.

The following tables summarize the HTM securities with unrealized losses as of ~~September~~June 30, ~~2017~~2018, and December 31, ~~2016~~2017. The unrealized losses are aggregated by major security type and the length of time that individual securities have been in a continuous unrealized loss position. Total unrealized losses in the following table will not agree to the total gross unrecognized holding losses in the table above. The unrealized losses in the following table also include non-credit-related OTTI losses recognized in AOCI.

Federal Home Loan Bank of San Francisco

Notes to Financial Statements (continued)

As indicated in the tables above, the Bank’s investments classified as HTM had unrealized losses on CalHFA bonds and MBS. The unrealized losses associated with the CalHFA bonds were mainly due to an illiquid market, credit concerns regarding the underlying mortgage collateral, and credit concerns regarding the monoline insurance providers, causing these investments to be valued at a discount to their acquisition 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. The unrealized losses associated with the PLRMBS were primarily due to illiquidity in the PLRMBS 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.

Redemption Terms. The amortized cost, carrying value, and estimated fair value of non-MBS securities by contractual maturity (based on contractual final principal payment) and of MBS as of ~~September~~June 30, ~~2017~~2018, and December 31, ~~2016~~2017, are shown below. Expected maturities of MBS will differ from contractual maturities because borrowers generally have the right to prepay the underlying obligations without prepayment fees.

(1)	Amortized cost includes unpaid principal balance, unamortized premiums and discounts, and previous OTTI recognized in earnings. The carrying value of HTM securities represents amortized cost after adjustment for non-credit-related OTTI recognized in AOCI.

See Note 6 – Other-Than-Temporary Impairment Analysis for information on the transfers of securities between the AFS portfolio and the HTM portfolio.

Note 6 — Other-Than-Temporary Impairment Analysis

On a quarterly basis, the Bank evaluates its individual AFS and HTM investment securities in an unrealized loss position for OTTI. As part of this evaluation, the Bank considers whether it intends to sell each debt security and whether it is more likely than not that it will be required to sell the debt security before its anticipated recovery of the amortized cost basis. If either of these conditions is met, the Bank recognizes an OTTI charge to earnings equal to the entire difference between the security’s amortized cost basis and its fair value at the statement of condition date. For securities in an unrealized loss position that do not meet either of these conditions, the Bank considers

whether it expects to recover the entire amortized cost basis of the security by comparing its best estimate of the present value of the cash flows expected to be collected from the security with the amortized cost basis of the

security. If the Bank’s best estimate of the present value of the cash flows expected to be collected is less than the amortized cost basis, the difference is considered the credit loss.

PLRMBS. A significant input to the Bank’s cash flow analysis of its PLRMBS is the forecast of future housing price changes. The OTTI Governance Committee of the Federal Home Loan Banks (FHLBanks) developed a short-term housing price forecast with projected changes ranging from a decrease of ~~6.0%~~8.0% to an increase of 13.0% over the 12-month period beginning ~~July~~April 1, ~~2017.~~2018. For the vast majority of markets, the projected short-term housing price changes range from an increase of ~~1.0%~~2.0% to an increase of ~~6.0%~~7.0%. Thereafter, a unique path is projected for each geographic area based on an internally developed framework derived from historical data.

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 determined to be other-than-temporarily impaired as of ~~September~~June 30, ~~2017~~2018 (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 amount of credit loss recognized in earnings during the ~~third~~second quarter of ~~2017~~2018, 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.

Changes in circumstances may cause the Bank to change its intent to hold a certain security to maturity without calling into question its intent to hold other debt securities to maturity in the future. The sale or transfer of an HTM security because of certain changes in circumstances, such as evidence of significant deterioration in the issuers’ creditworthiness, is not considered to be inconsistent with its original classification. In addition, other events that are isolated, nonrecurring, or unusual for the Bank that could not have been reasonably anticipated may cause the Bank to sell or transfer an HTM security without necessarily calling into question its intent to hold other debt securities to maturity.

~~The~~In general, the Bank ~~elected~~elects to transfer any PLRMBS that incurred a credit-related OTTI charge during the applicable period from the Bank’s held-to-maturity portfolio to its available-for-sale portfolio at their fair values. The Bank recognized an OTTI credit loss on these held-to-maturity PLRMBS, which the Bank believes is evidence of a significant decline in the issuers’ creditworthiness. The decline in the issuers’ creditworthiness is the basis for the transfers to the available-for-sale 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 does not intend to sell its other-than-temporarily impaired securities 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 following table summarizes the PLRMBS transferred from the Bank’s HTM portfolio to its AFS portfolio during the three and six months ended June 30, 2018. The amounts shown represent the values when the securities were transferred from the HTM portfolio to the AFS portfolio. The Bank did not transfer any PLRMBS from its HTM portfolio to its AFS portfolio during the three and ~~nine~~six months ended ~~September~~June 30, ~~2017~~ ~~and 2016.~~2017.

For the Bank’s PLRMBS that were not other-than-temporarily impaired as of ~~September~~June 30, ~~2017~~2018, the Bank has experienced net unrealized losses primarily because of illiquidity in the PLRMBS 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. The Bank does not intend to sell these securities, it is not more likely than not that the Bank will be required to sell these securities before its anticipated recovery of the remaining amortized cost basis, and the Bank expects to recover the entire amortized cost basis of these securities. As a result, the Bank determined that, as of ~~September~~June 30, ~~2017~~2018, all of the gross unrealized losses on these PLRMBS are temporary. These securities were included in the securities that the Bank reviewed and analyzed for OTTI as discussed above, and the analyses performed indicated that these securities were not other-than-temporarily impaired.

All Other Available-for-Sale and Held-to-Maturity Investments. For the Bank’s investments in housing finance agency bonds, which were issued by CalHFA, the gross unrealized losses were mainly due to an illiquid market, credit concerns regarding the underlying mortgage collateral, and credit concerns regarding the monoline insurance providers, causing these investments to be valued at a discount to their acquisition cost. The Bank independently modeled cash flows for the underlying collateral, using assumptions for default rates and loss severity that a market participant would deem reasonable, and concluded that the available credit support within the CalHFA structure more than offset the projected underlying collateral losses. The Bank determined that, as of ~~September~~June 30, ~~2017~~2018, all of the gross unrealized losses on the bonds are temporary because the underlying collateral and credit enhancements were sufficient to protect the Bank from losses. As a result, the Bank expects to recover the entire amortized cost basis of these securities.

government is sufficient to protect the Bank from losses. As a result, the Bank determined that, as of ~~September~~June 30, ~~2017~~2018, all of the gross unrealized losses on its agency MBS are temporary.

Note 7 — Advances

The Bank offers a wide range of fixed and adjustable rate advance products with different maturities, interest rates, payment characteristics, and option features. Fixed rate advances generally have maturities ranging from one day to 30 years. Adjustable rate advances generally have maturities ranging from less than 30 days to 10 years, with the interest rates resetting periodically at a fixed spread to LIBOR or to another specified index.

Redemption Terms. The Bank had advances outstanding, excluding overdrawn demand deposit accounts, at interest rates ranging from ~~0.71%~~0.86% to 8.57% at ~~September~~June 30, ~~2017~~2018, and ~~0.43%~~0.79% to 8.57% at December 31, ~~2016~~2017, as summarized below.

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 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 partial prepayment symmetry outstanding totaling ~~$4,325~~$5,109 at ~~September~~June 30, ~~2017~~2018, and $~~3,647~~4,619 at December 31, ~~2016~~2017. Some advances may be repaid on pertinent call dates without prepayment fees (callable advances). The Bank had callable advances outstanding totaling $~~17,903~~12,817 at ~~September~~June 30, ~~2017~~2018, and $~~15,505~~18,373 at December 31, ~~2016~~2017.

The Bank’s advances at ~~September~~June 30, ~~2017~~2018, ~~and~~ included $10 of putable advances. The Bank had no outstanding putable advances at December 31, ~~2016, included~~ ~~$25~~ ~~and $125 of putable advances, respectively.~~2017. 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 ~~September~~June 30, ~~2017~~2018, and December 31, ~~2016~~2017, by the earlier of the year of contractual maturity or next call date for callable advances and by the earlier of the year of contractual maturity or next put date for putable advances.

The Bank may use derivatives to adjust the repricing and options characteristics of advances to more closely match the characteristics of the Bank’s funding liabilities. In general, whenever a member executes a fixed or variable rate advance with embedded options, the Bank will simultaneously execute an interest rate exchange agreement with terms that offset the terms and embedded options in the advance. The combination of the advance and the interest rate exchange agreement effectively creates a variable rate asset. This type of hedge relationship receives fair value option accounting treatment. In addition, for certain advances for which the Bank has elected the fair value option, the Bank will simultaneously execute an interest rate exchange agreement with terms that economically offset the terms of the advance. However, this type of hedge is treated as an economic hedge because these combinations generally do not meet the requirements for fair value hedge accounting treatment. For more information, see Note 15 – Derivatives and Hedging Activities and Note 16 – Fair Value.

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 ~~September~~June 30, ~~2017~~2018, or December 31, ~~2016~~2017. 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 16 – 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. The Bank records prepayment fees net of any associated fair value adjustments related to prepaid advances that were hedged. The net amount of prepayment fees is reflected as interest income in the Statements of Income for the three and ~~nine~~ ~~months ended~~ ~~September 30, 2017~~ ~~and~~ ~~2016, as follows:~~

Medium-term loans have original contractual terms of 15 years or less, and long-term loans have contractual terms of more than 15 years.

For information related to the Bank’s credit risk on mortgage loans and allowance methodology for credit losses, see Note 9 – Allowance for Credit Losses.

Note 9 — Allowance for Credit Losses

The Bank has established an allowance methodology for each of its portfolio segments: advances, letters of credit, and other extensions of credit, collectively referred to as “credit products,” mortgage loans held for portfolio, term securities purchased under agreements to resell, and term Federal funds sold. For more information on these portfolio segments, see “Item 8. Financial Statements and Supplementary Data – Note 10 – Allowance for Credit Losses” in the Bank’s ~~2016~~2017 Form 10-K.

Credit Products. The Bank manages its credit exposure related to credit products 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. At ~~September~~June 30, ~~2017,~~2018, and December 31, ~~2016,~~2017, none of the Bank’s credit products were past due, on nonaccrual status, or considered impaired. There were no troubled debt restructurings related to credit products during the ~~nine~~six months ended ~~September~~June 30, ~~2017,~~2018, or during ~~2016.~~2017.

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 as of ~~September~~June 30, ~~2017,~~2018, the Bank expects to collect all amounts due according to the contractual terms. Therefore, no allowance for losses on credit products was deemed necessary by the Bank. The Bank has never experienced any credit losses on its credit products.

Mortgage Loans Held for Portfolio. The following table presents information on delinquent mortgage loans as of June 30, 2018, and December 31, 2017.

The Bank and any participating financial institution share in the credit risk of the loans sold by that institution as specified in a master agreement. Loans purchased under the MPF Program generally ~~have~~had a credit risk exposure at the time of purchase that, as determined by the MPF Program methodology, would be expected from an equivalent ~~to assets~~investment rated AA if purchased prior to April 2017, or ~~to assets~~ rated BBB ~~for loans~~if purchased since April 2017, taking ~~into~~i

nto consideration the credit risk sharing structure mandated by the Finance Agency’s acquired member assets (AMA) regulation. The MPF Program structures potential credit losses on conventional MPF loans into layers with respect to each pool of loans purchased by the Bank under a single master commitment, as follows:


1.	The first layer of protection against loss is the liquidation value of the real property securing the loan.


2.	The next layer of protection comes from the primary mortgage insurance that is required for loans with a loan-to-value ratio greater than 80%, if still in place.


3.	Losses that exceed the liquidation value of the real property and any primary mortgage insurance, up to an agreed-upon amount called the first loss account for each master commitment, are incurred by the Bank.


4.	Losses in excess of the first loss account for each master commitment, up to an agreed-upon amount called the credit enhancement amount, are covered by the participating financial institution’s credit enhancement obligation at the time losses are incurred.


5.	Losses in excess of the first loss account and the participating financial institution’s remaining credit enhancement for the master commitment, if any, are incurred by the Bank.

Allowance for Credit Losses on MPF Loans –The Bank evaluates the allowance for credit losses on MPF mortgage loans based on two components. The first component applies to each individual loan that is specifically identified as impaired. The Bank evaluates the exposure on these loans by considering the first layer of loss protection (the liquidation value of the real property securing the loan) and the availability and collectability of credit enhancements under the terms of each master commitment and records a provision for credit losses. For this component, the Bank ~~established~~had no allowance for credit losses for MPF Original and MPF Plus loans as of June 30, 2018, and a de minimis allowance for credit losses for MPF Original and MPF Plus loans as of ~~September 30, 2017, and~~ December 31, ~~2016.~~2017.

The second component applies to loans that are not specifically identified as impaired and is based on the Bank’s estimate of probable credit losses on those loans as of the financial statement date. The Bank evaluates the credit loss exposure on a loan pool basis considering various observable data, such as delinquency statistics, past performance, current performance, loan portfolio characteristics, collateral valuations, industry data, and prevailing economic conditions. The Bank also considers the availability and collectability of credit enhancements from participating financial institutions or from mortgage insurers under the terms of each master commitment. For this component, the Bank established an allowance for credit losses for MPF Original and MPF Plus loans totaling de minimis amounts as of ~~September~~June 30, ~~2017,~~2018, and December 31, ~~2016.~~2017.

Troubled Debt Restructurings –Troubled debt restructuring (TDR) is considered to have occurred when a concession is granted to the debtor for economic or legal reasons related to the debtor’s financial difficulties and that concession would not have been considered otherwise. An MPF loan considered a TDR is individually evaluated for impairment when determining its related allowance for credit losses. Credit loss is measured by factoring in expected cash flow shortfalls incurred as of the reporting date as well as the economic loss attributable to delaying the original contractual principal and interest due dates, if applicable.

The recorded investment of the Bank's nonperforming MPFloans classified as TDRs totaled $3$2 as of ~~September~~June 30, ~~2017,~~2018, and $3 as of December 31, 2016. During the three and nine months ended September 30, 2017 and 2016, the difference between the pre- and post-modification recorded investment in TDRs that occurred during the year was de minimis. None of the MPF loans classified as TDRs within the previous 12 months experienced a payment default.2017.

Term Federal Funds Sold. The Bank invests in Federal funds sold with counterparties that are considered by the Bank to be of investment quality, and these investments are evaluated for purposes of an allowance for credit losses only if the investment is not paid when due. All investments in Federal funds sold as of ~~September~~June 30, ~~2017~~2018, and December 31, ~~2016~~2017, were repaid or are expected to be repaid according to the contractual terms.

Note 10 — 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~~pe

Note 11 — Consolidated Obligations

Consolidated obligations, consisting of consolidated obligation bonds and discount notes, are jointly issued by the FHLBanks through the Office of Finance, which serves as the FHLBanks’ agent. As provided by the 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 ~~Statement~~Statements and Supplementary Data – Note 20 – Commitments and Contingencies” in the Bank’s ~~2016~~2017 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 ~~September~~June 30, ~~2017~~2018, and December 31, ~~2016~~2017.

The Bank’s participation in consolidated obligation bonds outstanding includes callable bonds of ~~$8,300~~$10,645 at ~~September~~June 30, ~~2017~~2018, and $~~4,670~~9,612 at December 31, ~~2016~~2017. When a callable bond for which the Bank is the primary obligor is issued, the Bank may simultaneously enter into an interest rate swap (in which the Bank pays a variable rate and receives a fixed rate) with a call feature that mirrors the call option embedded in the bond (a sold callable swap). The Bank had notional amounts of interest rate exchange agreements hedging callable bonds of $~~5,414~~7,141 at ~~September~~June 30, ~~2017~~2018, and $~~2,125~~6,406 at December 31, ~~2016~~2017. The combined sold callable swaps and callable bonds enable the Bank to meet its funding needs at costs not otherwise directly attainable solely through the issuance of non-callable debt, while effectively converting the Bank’s net payment to an adjustable rate.

The Bank’s participation in consolidated obligation bonds at ~~September~~June 30, ~~2017~~2018, and December 31, ~~2016~~2017, was as follows:

Note 13 — Capital

Capital Requirements. Under the 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. 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. ~~The~~ 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.

~~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. In January 2017, the Framework was amended and approved by the Bank’s Board of Directors to include a dividend philosophy to endeavor to pay a quarterly dividend at an annualized rate between 5% and 7%, which was ~~intended to be~~ considered by the Bank’s Board of Directors beginning with the Bank’s second quarter 2017 dividend declaration. 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 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 three-month LIBOR 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 ~~219%~~224% as of ~~September~~June 30, ~~2017.~~2018.

In addition, the Bank monitors the condition of its PLRMBS portfolio, the ratio of the Bank’s estimated market value of total capital to par value of capital stock, its overall financial performance and retained earnings, developments in the mortgage and credit markets, and other relevant information as the basis for determining the payment of dividends and the repurchase of excess capital stock each quarter.

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.~~period, and maintains an amount of total retained earnings at least equal to its required retained earnings as described in the Framework. Prior to July 2017, the Bank’s Framework had three categories of restricted retained earnings: Valuation Adjustments, Other (which represented a targeted amount), and the Joint Capital Enhancement (JCE Agreement). Under the Framework, the Bank’s ~~retained earnings methodology determined the Bank’s~~ required amount of restricted retained ~~earnings.~~earnings was determined using the Bank’s retained earnings methodology. As determined byusing the Bank’s ~~Framework,~~methodology, from July 2015 to January 2017, the Bank’s restricted retained earnings requirement was $2,000, and from January 2017 to July 2017, the Bank’s restricted retained earnings requirement was $2,300.

In July 2017, the Bank’s Board of Directors approved the transfer of all amounts classified as restricted retained earnings, other than the amounts related to the JCE Agreement, to unrestricted retained earnings. As a conforming change related to the transfer, the Bank’s Board of Directors amended the Framework to eliminate two of the categories of restricted retained earnings (Valuation Adjustments and Other) and approved revisions to the Bank’s retained earnings methodology to provide for a required level of ~~all~~total retained earnings of $2,300 for loss protection, capital compliance, and business growth. In January 2018, the methodology was further revised to provide a required level of total retained earnings of $2,500. The Bank satisfies its retained earnings requirement with both restricted retained earnings (i.e., amounts related to the JCE Agreement) and unrestricted retained earnings.

For more information on restricted retained earnings and the Bank’s Framework, see “Item 8. Financial Statements and Supplementary Data – Note 15 – Capital” in the Bank’s ~~2016~~2017 Form 10-K.

Dividend Payments – Finance Agency rules state that FHLBanks may declare and pay dividends only from previously retained earnings or current net earnings, and may not declare or pay dividends based on projected or 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. As of ~~September~~June 30, ~~2017,~~2018, the Bank’s excess capital stock totaled ~~$452,~~$152, or ~~0.41%~~0.14% of total assets.

In the ~~third~~second quarter of ~~2017,~~2018, the Bank paid dividends at an annualized rate of 7.00%, totaling ~~$51,~~$63, including ~~$44~~$58 in dividends on capital stock and $7$5 in dividends on mandatorily redeemable capital stock. In the ~~third~~second quarter of ~~2016, the Bank paid dividends at an annualized rate of 9.17%, totaling $63, including $52 in dividends on capital stock and $11 in dividends on mandatorily redeemable capital stock.~~

Notes to Financial Statements (continued)

2017, the Bank paid dividends at an annualized rate of 7.00%, totaling $48, including $41 in dividends on capital stock and $7 in dividends on mandatorily redeemable capital stock.

In the first ~~nine~~six months of 2018, the Bank paid dividends at an annualized rate of 7.00%, totaling $122, including $111 in dividends on capital stock and $11 in dividends on mandatorily redeemable capital stock. In the first six months of 2017, the Bank paid dividends at an annualized rate of ~~7.69%~~8.04%, totaling ~~$164,~~$113, including ~~$139~~$95 in dividends on capital stock and $25 in dividends on mandatorily redeemable capital stock. In the first nine months of 2016, the Bank paid dividends at an annualized rate of 8.70%, totaling $179, including $146 in dividends on capital stock and $33$18 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 ~~October~~July 26, ~~2017,~~2018, the Bank’s Board of Directors declared a cash dividend on the capital stock outstanding during the ~~third~~second quarter of ~~2017~~2018 at an annualized rate of 7.00%, totaling ~~$55,~~$56, including ~~$48~~$51 in dividends on capital stock and $7$5 in dividends on mandatorily redeemable capital stock. The Bank recorded the dividend on ~~October~~July 26, ~~2017.~~2018. The Bank expects to pay the dividend on ~~November~~August 13, ~~2017.~~2018. Dividends on mandatorily redeemable capital stock will be recognized as interest expense in the ~~fourth~~third quarter of ~~2017.~~2018.

Excess Capital Stock – 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 must give the shareholder 15 days’ written notice; however, the shareholder may waive this notice period. 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 repurchased ~~$98~~$700 and ~~$275~~$60 in excess capital stock induring the ~~third~~second quarter of ~~2017~~2018 and ~~2016,~~2017, respectively, and ~~$331~~$1,128 and ~~$663~~$233 in excess capital stock induring the first ~~nine~~six months of 2018 and 2017, ~~and 2016,~~ 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 ~~third~~second quarter of ~~2017~~2018 and ~~2016,~~2017, the Bank redeemed ~~$7 and $1, respectively,~~de minimis amounts in mandatorily redeemable capital stock, for which the five-year redemption period had expired, at its $100 par value. 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.

On ~~October 26, 2017,~~April 9, 2018, the ~~Bank announced that it plans~~Bank’s Board of Directors revised the Framework to ~~repurchase~~change the Bank’s practice of repurchasing the surplus capital stock of all members and the excess capital stock of all ~~nonmember shareholders on November 14, 2017.~~former members from a quarterly schedule to a daily schedule. Surplus capital stock is defined as any stock holdings in excess of 115% of a member’s minimum stock requirement. Effective April 24, 2018, the Bank began calculating 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 will continue to meet its minimum capital stock requirement after the repurchase. In accordance with the revised Framework, the Bank repurchased $363 of excess capital stock on April 24, 2018. The Bank may change this practice at any time. All repurchases of capital stock are at the Bank’s discretion, subject to certain statutory and regulatory requirements and to the Bank’s Risk Management Policy, Capital Plan, and the Framework.

Excess capital stock totaled ~~$452~~$152 and $493 as of ~~September~~June 30, ~~2017, which included surplus capital stock of $261. Excess capital stock totaled $488 as of~~2018, and December 31, ~~2016, which included surplus capital stock of $325.~~2017, respectively.

Note 14 — 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 and hedging activities” in other income and excludes interest expense that is recorded in “Mandatorily redeemable capital stock.” Other key financial information, such as any credit-related OTTI losses on the Bank’s PLRMBS, other expenses, and assessments, is not included in the segment reporting analysis, but is 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 17 – Segment Information” in the Bank’s ~~2016~~2017 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 ~~nine~~six months ended ~~September~~June 30, ~~2017~~2018 and ~~2016~~2017.

Note 15 — 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 obligation bonds to create variable rate structures. The interest rate exchange agreements are generally executed at

~~Table of Contents~~

~~Federal Home Loan Bank of San Francisco~~

~~Notes to Financial Statements (continued)~~

the same time the advances and bonds are transacted and generally have the same maturity dates as the related advances and bonds. The Bank transacts most of its derivatives with large banks and major broker-dealers. Some of these banks and broker-dealers or their affiliates buy, sell, and distribute consolidated obligations. ~~Over-the-counter derivatives~~Derivatives may be either uncleared or cleared. In an uncleared derivative transaction, the Bank’s counterparty is the executing bank or broker-dealer. In a cleared derivative transaction, the Bank may execute the transaction either directly with the executing bank or broker-dealer or on a swap execution facility, but in either case, the Bank’s counterparty is a derivatives clearing organization or clearinghouse once the derivative transaction has been accepted for clearing. The Bank is not a derivatives dealer and does not trade derivatives for short-term profit.

Additional uses of interest rate exchange agreements include: (i) offsetting embedded features in assets and liabilities, (ii) hedging anticipated issuance of debt, (iii) matching against consolidated obligation discount notes or bonds to create the equivalent of callable or non-callable fixed rate debt, (iv) modifying the repricing frequency of assets and liabilities, (v) matching against certain advances and consolidated obligations for which the Bank elected the fair value option, and (vi) exactly offsetting other derivatives cleared at a derivatives clearing organization. The Bank’s use of interest rate exchange agreements results in one of the following classifications: (i) a fair value hedge of an underlying financial instrument or (ii) an economic hedge of assets, or liabilities, or ~~(iii) an intermediary transaction for members.~~other derivatives.

The Bank primarily uses the following derivative instruments:

Interest Rate Swaps – An interest rate swap is an agreement between two entities to exchange cash flows in the future. The agreement sets the dates on which the cash flows will be paid and the manner in which the cash flows will be calculated. One of the simplest forms of an interest rate swap involves the promise by one party to pay cash flows equivalent to the interest on a notional principal amount at a predetermined fixed rate for a given period of time. In return for this promise, the party receives cash flows equivalent to the interest on the same notional principal amount at a variable rate for the same period of time. The variable rate received or paid by the Bank in most interest rate exchange agreements is either indexed to ~~LIBOR.~~LIBOR or to the overnight index swap rate.

Interest Rate Caps and Floors – In a cap agreement, additional cash flow is generated if the price or interest rate of an underlying variable rate rises above a certain threshold (or cap) price. In a floor agreement, additional cash flow is generated if the price or interest rate of an underlying variable rate falls below a certain threshold (or floor) price. Caps and floors may be used in conjunction with assets or liabilities. In general, caps and floors are designed as protection against the interest rate on a variable rate asset or liability rising above or falling below a certain level.

Hedging Activities. The Bank documents at inception all relationships between derivatives designated as hedging instruments and hedged items, its risk management objectives and strategies for undertaking various hedge transactions, and its method of assessing hedge effectiveness. Derivatives designated as fair value hedges may be transacted to hedge: (i) assets and liabilities on the Statement of Condition, (ii) firm commitments, or (iii) forecasted transactions. The Bank also formally assesses (both at hedge inception and on an ongoing basis) whether the hedging

Table of Contents

Federal Home Loan Bank of San Francisco

Notes to Financial Statements (continued)

derivatives have been effective in offsetting changes in the fair value of hedged items attributable to the hedged risk and whether those derivatives may be expected to remain effective hedges in future periods. The Bank typically uses regression analyses or other statistical analyses to assess the effectiveness of its hedges. When it is determined that a derivative has not been or is not expected to be effective as a hedge, the Bank discontinues hedge accounting prospectively.

The Bank discontinues hedge accounting prospectively when: (i) it determines that the derivative is no longer effective in offsetting changes in the fair value of a hedged item (including hedged items such as firm commitments or forecasted transactions); (ii) the derivative and/or the hedged item expires or is sold, terminated, or exercised; (iii) it is no longer probable that the forecasted transaction will occur in the originally expected period; (iv) a hedged firm commitment no longer meets the definition of a firm commitment; (v) it determines that designating the derivative as a hedging instrument is no longer appropriate; or (vi) it decides to use the derivative to offset changes in the fair value of other derivatives or instruments carried at fair value.

~~Table of Contents~~

~~Federal Home Loan Bank of San Francisco~~

~~Notes to Financial Statements (continued)~~

The Bank may have the following types of hedged items:

Investments–The Bank may invest in U.S. Treasury and agency obligations, agency MBS, and the taxable portion of highly rated state or local housing finance agency obligations. In the past, the Bank has also invested in PLRMBS rated AAA at the time of acquisition. The interest rate and prepayment risk associated with these investment securities is managed through a combination of debt issuance and derivatives. The Bank may manage prepayment risk and interest rate risk by funding investment securities with consolidated obligations that have call features or by hedging the prepayment risk with a combination of consolidated obligations and callable swaps. The Bank may execute callable swaps in conjunction with the issuance of certain liabilities to create funding that is economically equivalent to fixed rate callable debt. Although these derivatives are economic hedges against prepayment risk and are designated to individual liabilities, they do not receive either fair value or cash flow hedge accounting treatment. Investment securities may be classified as trading, AFS, or HTM.

The Bank may also manage the risk arising from changing market prices or cash flows of investment securities classified as trading by entering into interest rate exchange agreements (economic hedges) that offset the changes in fair value or cash flows of the securities. The market value changes of both the trading securities and the associated interest rate exchange agreements are included in other income in the Statements of Income.

Advances– The Bank offers a wide range of advances structures to meet members’ funding needs. These advances may have maturities up to 30 years with fixed or adjustable rates and may include early termination features or options. The Bank may use derivatives to adjust the repricing and options characteristics of advances to more closely match the characteristics of the Bank’s funding liabilities. In general, whenever a member executes a fixed rate advance, fixed rate advance with embedded options, or a variable rate advance with embedded options, the Bank will simultaneously execute an interest rate exchange agreement with terms that offset the terms and any embedded options in the advance. The combination of the advance and the interest rate exchange agreement effectively creates a variable rate asset.

~~In addition, for certain~~ Fixed rate advances ~~for which the Bank has elected the fair value option, the Bank will simultaneously execute~~without options that are offset with an interest rate exchange agreement are generally treated as fair value hedges. Advances with ~~terms that~~embedded options are recorded using the fair value option and are economically ~~offset the terms of the advance.~~hedged using interest rate exchange agreements.

Mortgage Loans–The Bank’s investment portfolio includes fixed rate mortgage loans. The prepayment options embedded in mortgage loans can result in extensions or contractions in the expected repayment of these investments, depending on changes in estimated prepayment speeds. The Bank manages the interest rate risk and prepayment risk associated with fixed rate mortgage loans through a combination of debt issuance and derivatives. The Bank uses both callable and non-callable debt to achieve cash flow patterns and market value sensitivities for liabilities similar to those expected on the mortgage loans. Net income could be reduced if the Bank replaces prepaid mortgage loans with lower-yielding assets and the Bank’s higher funding costs are not reduced accordingly.

Federal Home Loan Bank of San Francisco

Notes to Financial Statements (continued)

The Bank executes callable swaps in conjunction with the issuance of certain consolidated obligations to create funding that is economically equivalent to fixed rate callable bonds. Although these derivatives are economic hedges against the prepayment risk of specific loan pools and are referenced to individual liabilities, they do not receive either fair value or cash flow hedge accounting treatment.

Consolidated Obligations – Consolidated obligation bonds may be structured to meet the Bank’s or the investors’ needs. Common structures include fixed rate bonds with or without call options and adjustable rate bonds with or without embedded options. In general, when bonds are issued, the Bank simultaneously executes an interest rate exchange agreement with terms that offset the terms and embedded options, if any, of the consolidated obligation bond. This combination of the consolidated obligation bond and the interest rate exchange agreement effectively creates an adjustable rate bond. The cost of this funding combination is generally lower than the cost that would be available through the issuance of an adjustable rate bond alone. These transactions generally receive fair value hedge accounting treatment.

~~Table of Contents~~

~~Federal Home Loan Bank of San Francisco~~

~~Notes to Financial Statements (continued)~~

When the Bank issues consolidated obligation discount notes, it may also simultaneously enter into an interest rate exchange agreement to convert the fixed rate discount note to an adjustable rate discount note. This type of hedge is treated as an economic hedge.

In addition, when certain consolidated obligation bonds for which the Bank has elected the fair value option are issued, the Bank simultaneously executes an interest rate exchange agreement with terms that economically offset the terms of the consolidated obligation bond. However, this type of hedge is treated as an economic hedge because these combinations do not meet the requirements for fair value hedge accounting treatment.

~~Intermediation and~~ Offsetting Derivatives– As an additional service to its members, the Bank has in the past entered into offsetting interest rate exchange agreements, acting as an intermediary between offsetting derivative transactions with members and other counterparties. This intermediation allows members indirect access to the derivatives market. The Bank ~~also~~ enters into derivatives to offset the economic effect of other derivatives that are no longer designated to advances, investments, or consolidated obligations. ~~Neither type of offsetting~~Offsetting derivatives ~~receives~~do not receive hedge accounting treatment and ~~both~~ are separately marked to market through earnings. The net result of the accounting for these derivatives does not significantly affect the operating results of the Bank.

~~The notional principal of the interest rate exchange agreements associated with derivatives with members or offsetting derivatives with other counterparties was $64 and $89, at~~ ~~September 30, 2017, and~~ ~~December 31, 2016, respectively.~~

The notional amount of an interest rate exchange agreement serves as a factor in determining periodic interest payments or cash flows received and paid. However, the notional amount of derivatives represents neither the actual amounts exchanged nor the overall exposure of the Bank to credit risk and market risk. The risks of derivatives can be measured meaningfully on a portfolio basis by taking into account the counterparties, the types of derivatives, the items being hedged, and any offsets between the derivatives and the items being hedged.

The following table summarizes the notional amount and fair value of derivative instruments, including the effect of netting adjustments and cash collateral as of ~~September~~June 30, ~~2017~~2018, and December 31, ~~2016~~2017. For purposes of this disclosure, the derivative values include the fair value of derivatives and related accrued interest.

Credit Risk – The Bank is subject to credit risk as a result of 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 in the event that the clearing agent or the clearinghouse fails to meet its obligations. The use of cleared derivatives, however, mitigates the Bank’s overall credit risk exposure because a central counterparty is substituted for individual ~~counterparties~~counterparties. Variation margin and ~~variation~~initial margin isare posted ~~daily~~ for changes in the value and risk profile of cleared ~~derivatives through a clearing agent.~~derivatives. 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 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.

Note 16 — 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 ~~September~~June 30, ~~2017~~2018, and December 31, ~~2016~~2017. 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.

The following tables present the carrying value, the estimated fair value, and the fair value hierarchy level of the Bank’s financial instruments at ~~September~~June 30, ~~2017~~2018, and December 31, ~~2016~~2017. The Bank records trading securities, AFS

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.

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:

~~Table of Contents~~

~~Federal Home Loan Bank of San Francisco~~

~~Notes to Financial Statements (continued)~~

(1) quoted prices for similar assets or liabilities in active markets; (2) quoted prices for identical or similar

Table of Contents

Notes to Financial Statements (continued)

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 ~~September~~June 30, ~~2017~~2018:

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. Such reclassifications are reported as transfers in or out as of the beginning of the quarter in which the changes occur. For the periods presented, the Bank did not have any reclassifications for transfers in or out of the fair value hierarchy levels.

Summary of Valuation Methodologies and Primary Inputs.

~~Cash~~The valuation methodologies and ~~Due from Banks~~–~~The estimated~~primary inputs used to develop the measurement of fair value ~~equals the carrying value.~~

~~Federal Funds Sold~~for assets and ~~Securities Purchased Under Agreements to Resell~~ ~~– The estimated~~liabilities that are measured at fair value on a recurring or nonrecurring basis in the Statements of overnight Federal funds sold and securities purchased under agreements to resell approximates the carrying value. The estimated fair value of term Federal funds sold and term securities purchased under agreements to resell has been determined by calculating the present value of expected cash flows for the instruments and reducing the amount for accrued interest receivable. The discount rates used in these calculationsCondition are ~~the replacement rates for comparable instruments with similar terms.~~listed below.

~~Interest-Bearing Deposits~~ –The fair value of deposits is generally equal to the carrying value of the deposits because the deposits are primarily overnight deposits or due on demand. The Bank determines the fair values of term deposits by calculating the present value of expected future cash flows from the deposits and reducing the amount for accrued interest receivable. The discount rates used in these calculations are the cost of deposits with similar terms.

Investment Securities – MBS – To value its MBS, the Bank obtains prices from multiple designated third-party pricing vendors when available. The pricing vendors use various proprietary models to price these securities. The inputs to those models are derived from various sources including, but not limited to: benchmark yields, reported trades, dealer estimates, issuer spreads, prices on benchmark securities, bids, offers, and other market-related data. Since many securities do not trade on a daily basis, the pricing vendors use available information as applicable, such as benchmark yield curves, benchmarking of like securities, sector groupings, and matrix pricing, to determine the prices for individual securities. Each pricing vendor has an established challenge process in place for all security valuations, which facilitates resolution of price discrepancies identified by the Bank.

~~Table of Contents~~

~~Federal Home Loan Bank of San Francisco~~

~~Notes to Financial Statements (continued)~~

At least annually, the Bank conducts reviews of the multiple pricing vendors to update and confirm its understanding of the vendors’ pricing processes, methodologies, and control procedures.

The Bank’s valuation technique for estimating the fair values of its MBS first requires the establishment of a median vendor price for each security. If three prices are received, the middle price is the median price; if two prices are received, the average of the two prices is the median price; and if one price is received, it is the median price (and also the default fair value) subject to additional validation. All vendor prices that are within a specified tolerance threshold of the median price are included in the cluster of vendor prices that are averaged to establish a default fair value. All vendor prices that are outside the threshold (outliers) are subject to further analysis including, but not limited to, comparison to prices provided by an additional third-party valuation service, prices for similar securities and/or dealer estimates, or use of internal model prices, which are deemed to be reflective of all relevant facts and circumstances that a market participant would consider. Such analysis is also applied in those limited instances where no third-party vendor price or only one third-party vendor price is available in order to arrive at an

Notes to Financial Statements (continued)

estimated fair value. If an outlier (or some other price identified in the analysis) is determined to be a better estimate of fair value, then the outlier (or the other price, as appropriate) is used as the fair value rather than the default fair value. If, instead, the analysis confirms that an outlier is (or outliers are) not representative of fair value and the default fair value is the best estimate, then the default fair value is used as the fair value.

If all vendor prices received for a security are outside the tolerance threshold level of the median price, then there is no default fair value, and the fair value is determined by an evaluation of all outlier prices (or the other prices, as appropriate) as described above.

As of ~~September~~June 30, ~~2017~~2018, multiple vendor prices were received for most of the Bank’s MBS, and the fair value estimates for most of those securities were determined in accordance with the Bank’s valuation technique based on these vendor prices. Based on the Bank’s reviews of the pricing methods employed by the third-party pricing vendors and the relative lack of dispersion among the vendor prices (or, in those instances in which there were outliers, the Bank’s additional analyses), the Bank believes that its fair value estimates are reasonable and that the fair value measurements are classified appropriately in the fair value hierarchy. Based on limited market liquidity for PLRMBS, the fair value measurements for these securities were classified as Level 3 within the fair value hierarchy.

Investment Securities – FFCB Bonds ~~and CalHFA Bonds~~ –The Bank estimates the fair values of these securities using the methodology described above for Investment Securities – MBS.

Advances Recorded Under the Fair Value Option –Because quoted prices are not available for advances, the fair values are measured using model-based valuation techniques (such as calculating the present value of future cash flows and reducing the amount for accrued interest receivable).

The Bank’s primary inputs for measuring the fair value of advances recorded under the fair value option are market-based consolidated obligation yield curve (CO Curve) inputs obtained from the Office of Finance. The CO Curve is then adjusted to reflect the rates on replacement advances with similar terms and collateral. These spread adjustments are not market-observable and are evaluated for significance in the overall fair value measurement and the fair value hierarchy level of the advance. The Bank obtains market-observable inputs for complex ~~advances.~~advances recorded under the fair value option. These inputs may include volatility assumptions, which are market-based expectations of future interest rate volatility implied from current market prices for similar options (swaption volatility and volatility skew). The discount rates used in these calculations are the replacement advance rates for advances with similar terms. Pursuant to the Finance Agency’s advances regulation, advances with an original term to maturity or repricing period greater than six months generally require a prepayment fee sufficient to make the Bank financially indifferent to the borrower’s decision to prepay the advances. The Bank determined that no adjustment is required to the fair value measurement of advances for prepayment fees. In addition, the Bank did not adjust its fair value measurement of advances recorded under the fair value option for creditworthiness primarily because advances were fully collateralized.

~~Table of Contents~~

~~Federal Home Loan Bank of San Francisco~~

~~Notes to Financial Statements (continued)~~

~~Mortgage Loans Held for Portfolio~~ – The estimated fair value for seasoned mortgage loans represents modeled prices based on observable market prices for seasoned agency mortgage-backed passthrough securities adjusted for differences in coupon, average loan rate, credit, and cash flow remittance between the Bank’s mortgage loans and the referenced instruments, while the estimated fair value for newly originated mortgage loans represents modeled prices based on MPF commitment rates. Market prices are highly dependent on the underlying prepayment assumptions. Changes in the prepayment speeds often have a material effect on the fair value estimates. These underlying prepayment assumptions are susceptible to material changes in the near term because they are made at a specific point in time.

~~Loans to and from Other FHLBanks~~ –~~Because these are overnight transactions, the estimated fair value approximates the recorded carrying value.~~

~~Accrued Interest Receivable and Payable~~ ~~– The estimated fair value approximates the carrying value of accrued interest receivable and accrued interest payable.~~

Other Assets – The estimated fair value of grantor trust assets is based on quoted market prices.

Derivative Assets and Liabilities –In general, derivative instruments transacted and held by the Bank for risk management activities are traded in over-the-counter markets where quoted market prices are not readily available. These derivatives are interest rate-related. For these derivatives, the Bank measures fair value using internally developed discounted cash flow models that use market-observable inputs, such as the overnight index swap (OIS) curve and volatility assumptions, which are market-based expectations of future interest rate volatility implied from current market prices for similar options (swaption volatility and volatility skew), adjusted for counterparty credit risk, as necessary.

The Bank is subject to credit risk because of the risk of potential nonperformance by its derivative counterparties. To mitigate this risk, the Bank executes uncleared derivative transactions only with highly rated derivative ~~dealers~~de

Notes to Financial Statements (continued)

alers and major banks (derivative dealer counterparties) that meet the Bank’s eligibility criteria. In addition, 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 either (i) limited to an absolute dollar credit exposure limit according to the counterparty’s long-term debt or deposit credit rating, as determined by rating agencies or (ii) set at zero (subject to a minimum transfer amount). The Bank clears its cleared derivative transactions only through clearing agents that meet the Bank’s eligibility requirements, and the Bank’s credit exposure to the clearinghouse is secured by variation margin received from the clearinghouse. All credit exposure from derivative transactions entered into by the Bank with member counterparties that are not derivative dealers must be fully secured by eligible collateral. The Bank evaluated the potential for the fair value of the instruments to be affected by counterparty credit risk and determined that no adjustments to the overall fair value measurements were required.

The fair values of the derivative assets and liabilities include accrued interest receivable/payable and cash collateral remitted to/received from counterparties. The estimated fair values of the accrued interest receivable/payable and cash collateral approximate their carrying values because of their short-term nature. The fair values of derivatives that met the netting requirements are presented on a net basis. If these netted amounts are positive, they are classified as an asset and, if negative, they are classified as a liability.

~~Deposits~~ –The fair value of deposits is generally equal to the carrying value of the deposits because the deposits are primarily overnight deposits or due on demand. The Bank determines the fair values of term deposits by calculating the present value of expected future cash flows from the deposits and reducing the amount for accrued interest payable. The discount rates used in these calculations are the cost of deposits with similar terms.

~~Table of Contents~~

~~Federal Home Loan Bank of San Francisco~~

~~Notes to Financial Statements (continued)~~

Consolidated Obligations Recorded Under the Fair Value Option –Because quoted prices in active markets are not generally available for identical liabilities, the Bank measures fair values using internally developed models that use primarily market-observable inputs. The Bank’s primary input for measuring the fair value of consolidated obligation bonds is a market-based CO Curve obtained from the Office of Finance. The Office of Finance constructs the CO Curve using the Treasury yield curve as a base curve, which is adjusted by indicative consolidated obligation spreads obtained from market-observable sources. These market indications are generally derived from pricing indications from dealers, historical pricing relationships, and market activity for similar liabilities, such as recent GSE issuances or secondary market activity. For consolidated obligation bonds with embedded options, the Bank also obtains market-observable inputs, such as volatility assumptions, which are market-based expectations of future interest rate volatility implied from current market prices for similar options (swaption volatility and volatility skew).

Adjustments may be necessary to reflect the Bank’s credit quality or the credit quality of the FHLBank System when valuing consolidated obligation bonds measured at fair value. The Bank monitors its own creditworthiness and the creditworthiness of the other FHLBanks and the FHLBank System to determine whether any adjustments are necessary for creditworthiness in its fair value measurement of consolidated obligation bonds. The credit ratings of the FHLBank System and any changes to the credit ratings are the basis for the Bank to determine whether the fair values of consolidated obligations recorded under the fair value option have been significantly affected during the reporting period by changes in the instrument-specific credit risk.

~~Mandatorily Redeemable Capital Stock~~ –The estimated fair value of capital stock subject to mandatory redemption is generally at par value as indicated by contemporaneous purchases, redemptions, and repurchases at par value. Fair value includes estimated dividends earned at the time of reclassification from capital to liabilities, until such amount is paid, and any subsequently declared capital stock dividend. The Bank’s capital stock can only be acquired by members at par value and redeemed or repurchased at par value, subject to statutory and regulatory requirements. The Bank’s capital stock is not traded, and no market mechanism exists for the exchange of Bank capital stock outside the cooperative ownership structure.

~~Commitments~~ – The estimated fair value of standby letters of credit is based on the present value of fees currently charged for similar agreements and is recorded in other liabilities. The estimated fair value of off-balance sheet fixed rate commitments to fund advances and commitments to issue consolidated obligations takes into account the difference between current and committed interest rates.

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 19 – Fair Values” in the Bank’s ~~2016~~2017 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 using fair value only for the 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 tables summarize the activity related to financial assets and liabilities for which the Bank elected the fair value option during the three and ~~nine~~six months ended ~~September~~June 30, ~~2017~~2018 and ~~2016:~~2017:

For instruments for which the fair value option has been elected, the related contractual interest income and contractual interest expense are recorded as part of net interest income on the Statements of Income. The remaining changes in fair value for instruments for which the fair value option has been elected are recorded as net gains/ (losses) on financial instruments held under the fair value option in the Statements of ~~Income. The change~~Income, except for changes in fair value ~~does not include changes in~~related to instrument-specific credit ~~risk.~~risk which are recorded in AOCI on the Statements of Condition. For advances and consolidated obligations recorded under the fair value option, the Bank determined that ~~no adjustments~~none of the remaining changes in fair value were related to ~~the fair values of these instruments for~~ instrument-specific credit risk ~~were necessary~~ for the three and ~~nine~~six months ended ~~September~~June 30, ~~2017~~2018 and ~~2016.~~2017. 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 ~~September~~June 30, ~~2017~~2018, and December 31, ~~2016~~2017:

(1)	At ~~September~~June 30, ~~2017~~2018, and December 31, ~~2016~~2017, none of these advances were 90 days or more past due or had been placed on nonaccrual status.

Note 17 — 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 ~~September~~June 30, ~~2017~~2018, 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 ~~$1,028,710~~

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. The original terms of these standby letters of credit range from 3314 days to 15 years, including a final expiration in ~~2032.~~2033. The Bank monitors the creditworthiness of members that have standby letters of credit. The value of the Bank’s obligations related to standby letters of credit is recorded in other liabilities and amounted to $22 at ~~September~~June 30, ~~2017~~2018, and ~~$24~~$19 at December 31, ~~2016~~2017. 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 on the letters of credit outstanding as of ~~September~~June 30, ~~2017~~2018, and December 31, ~~2016~~2017.

Commitments to fund advances totaled $1 at ~~September 30, 2017, and~~ $6 at December 31, ~~2016~~2017. There were no commitments to fund advances at June 30, 2018. Advances funded under advance commitments are fully collateralized at the time of funding (see Note 9 – Allowance for Credit Losses). Based on the Bank’s credit analyses of members’ financial condition and collateral requirements, the Bank deemed it unnecessary to record any additional liability on the advance commitments outstanding as of ~~September~~June 30, ~~2017~~2018, and December 31, ~~2016~~2017.

The Bank may enter into commitments that unconditionally obligate it to purchase mortgage loans from its members. Commitments are generally for periods not exceeding 60 days. Delivery commitments are recorded at fair value as derivative assets or derivative liabilities in the Statements of Condition.

The Bank executes over-the-counter uncleared interest rate exchange agreements with major banks and derivative entities affiliated with broker-dealers and has executed uncleared interest rate exchange agreements in the past with the Bank’s members. The Bank enters into master agreements with netting provisions and into bilateral credit support agreements with all active derivative dealer counterparties. All member counterparty master agreements, excluding those with derivative dealers, are subject to the terms of the Bank’s Advances and Security Agreement with members, and all member counterparties (except for those that are derivative dealers) must fully collateralize the Bank’s net credit exposure. For cleared derivatives, the clearinghouse is the Bank’s counterparty, and the Bank has clearing agreements with clearing agents that provide for delivery of initial margin to, and exchange of variation margin with, the clearinghouse. See Note 15 – Derivatives and Hedging Activities for additional information about the Bank’s pledged collateral and other credit-risk-related contingent features.

The Bank may be subject to various pending legal proceedings that may arise in the ordinary course of business. After consultation with legal counsel, the Bank does not anticipate that the ultimate liability, if any, arising out of these matters will have a material effect on its financial condition or results of operations.

All transactions with members, nonmembers, and their affiliates are entered into in the ordinary course of business. As of ~~September~~June 30, ~~2017~~2018, and December 31, ~~2016~~,2017, no shareholder owned more than 10% of the total voting interests in the Bank because of the statutory limit on members' voting rights. For more information on transactions with members and nonmembers, see “Item 8. Financial Statements and Supplementary Data – Note 21 – Transactions with Certain Members, Certain Nonmembers, and Other FHLBanks” in the Bank’s ~~2016~~2017 Form 10-K.

Transactions with Other FHLBanks. The Bank may occasionally enter into transactions with other FHLBanks. These transactions are summarized below.

Deposits with other FHLBanks. The Bank may, from time to time, maintain deposits with other FHLBanks. Deposits with other FHLBanks totaled ~~$1 and a~~ de minimis ~~amount~~amounts at ~~September~~June 30, ~~2017~~2018, and December 31, ~~2016~~2017, ~~respectively,~~ which were recorded in the Statements of Condition in the Cash and due from banks line item.

Overnight Funds. The Bank may borrow or lend unsecured overnight funds from or to other FHLBanks. All such transactions are at current market rates. Interest income and interest expense related to these transactions with other FHLBanks are included in other interest income and interest expense from other borrowings in the Statements of Income. Balances outstanding at period end with other FHLBanks, if any, are identified in the Bank’s financial statements. During the ~~nine~~six months ended ~~September~~June 30, ~~2017~~2018 and ~~2016,~~2017, the Bank extended overnight loans to other FHLBanks for ~~$1,005~~$280 and ~~$205,~~$1,005, respectively.

The impact to net interest income related to these transactions was de minimis ~~during both periods~~in any period in this report.

MPF Mortgage Loans. The Bank pays a transaction services fee to the FHLBank of Chicago for its participation in the MPF program. This fee is assessed monthly and is based on the amount of mortgage loans in which the Bank invested and which remain outstanding on its Statements of Condition. For the three and ~~nine~~six months ended ~~September~~June 30, ~~2017,~~2018, the Bank recorded a de minimis amount and $1, respectively, in MPF transaction services fee expense to the FHLBank of Chicago, which was recorded in the Statements of Income as other expense.

Quarterly Overview

The Bank serves eligible financial institutions in Arizona, California and Nevada, the three states that make up the Eleventh District of the FHLBank System. The Bank’s primary business is providing competitively priced, collateralized loans, known as advances, to its member institutions and certain qualifying housing associates. The Bank's principal source of funds is debt issued in the capital markets. All 11 FHLBanks issue debt in the form of consolidated obligations through the Office of Finance as their agent, and all 11 FHLBanks are jointly and severally liable for the repayment of all consolidated obligations.

The Bank experienced strong earnings in the second quarter of 2018. Net income for the quarter was ~~$81~~$104 million, compared with net income of ~~$291~~$80 million for the ~~third~~second quarter of ~~2016.~~ 2017. The $24 million increase in net income relative to the prior-year period primarily reflected higher net interest income, resulting from higher average balances of interest-earning assets, and an increase in other income related to improvements in net fair value gains and losses associated with derivatives, hedged items, and financial instruments carried at fair value. These increases in net income were partially offset by a voluntary charitable contribution of $5 million made by the Bank during the second quarter of 2018 for the Quality Jobs Fund, a donor-advised fund established to support quality job growth and small business expansion.

Retained earnings grew to ~~$3.2~~$3.3 billion at ~~September~~June 30, ~~2017,~~2018, from ~~$3.1~~$3.2 billion at December 31, ~~2016,~~2017, and the Bank paid dividends at an annualized rate of 7.00%, totaling ~~$51~~$122 million, including ~~$44~~$111 million in dividends on capital stock and $7$11 million in dividends on mandatorily redeemable capital stock during the ~~third~~second quarter of ~~2017.~~2018.

~~Net interest income increased by $23 million compared to the prior year period. The increase reflected higher average balances of interest-earning~~Total assets ~~combined with a higher net interest margin. Other income~~ decreased by $245 million, primarily because other income in the third quarter of 2016 included a gain on settlements of $240 million (after netting certain legal fees and expenses) relating to the Bank's private-label residential mortgage-backed securities (PLRMBS) litigation. The decrease in other income also reflected a voluntary charitable contribution of $10 million made by the Bank$17.2 billion during the third quarter of 2017 for the Quality Jobs Fund as well as a voluntary contribution of $1 million to the Affordable Housing Program (AHP) to offset the impact on the AHP assessment of the charitable contribution expense. In the first quarter of 2017, the Board of Directors approved an allocation of $100 million for the Quality Jobs Fund, a donor-advised fund established to support quality jobs growth and small business expansion, which is being funded by the Bank in incremental amounts over a two-year period.

~~During the first nine~~six months of ~~2017, total assets increased $17.6 billion,~~2018, to ~~$109.5~~$106.2 billion at ~~September~~June 30, ~~2017,~~2018, from ~~$91.9~~$123.4 billion at December 31, ~~2016, primarily reflecting an increase in period end advance balances, which increased~~2017. Total advances decreased $7.1 billion, to ~~$61.6~~$70.3 billion at ~~September~~June 30, ~~2017,~~2018, from ~~$49.8~~$77.4 billion at December 31, ~~2016.~~2017. In addition, investments ~~increased $4.8~~decreased $10.9 billion, to ~~$45.8~~$32.7 billion at ~~September~~June 30, ~~2017,~~2018, from ~~$41.0~~$43.6 billion at December 31, ~~2016,~~2017, primarily reflecting ~~an increase~~a decrease of $7.8 billion in securities purchased under agreements to resell and a decrease of $2.3 billion in Federal funds sold.

Accumulated other comprehensive income increased by ~~$197~~$12 million during the first ~~nine~~six months of ~~2017,~~2018, to ~~$308~~$330 million at ~~September~~June 30, ~~2017,~~2018, from$~~111~~318 million at December 31, ~~2016,~~2017, primarily as a result of improvement in the fair value of ~~PLRMBS~~the Bank’s private-label residential mortgage-backed securities (PLRMBS) classified as available-for-sale.

On ~~October~~July 26, ~~2017,~~2018, the Bank’s Board of Directors declared a quarterly cash dividend on the capital stock outstanding during the ~~third~~second quarter of ~~2017~~2018 at an annualized rate of 7.00%. The dividend will total ~~$55~~$56 million, including $7$5 million in dividends on mandatorily redeemable capital stock that will be reflected as interest expense in the ~~fourth~~third quarter of ~~2017.~~2018. The Bank recorded the dividend on ~~October~~July 26, ~~2017~~2018, and expects to pay the dividend on or about ~~November~~August 13, ~~2017~~2018.

As of ~~September~~June 30, ~~2017,~~2018, the Bank was in compliance with all of its regulatory capital requirements. The Bank’s total regulatory capital ratio was ~~5.8%~~6.1%, exceeding the 4.0% requirement. The Bank had $6.4 billion in permanent capital, exceeding its risk-based capital requirement of $2.0 billion.

The Bank plans to repurchase the surplus capital stock of all members and the excess capital stock of all nonmember shareholders on November 14, 2017. Surplus capital stock is defined as any stock holdings in excess of 115% of a member’s minimum capital stock requirement.

developments in the mortgage and credit markets, and other relevant information as the basis for determining the payment of dividends and the repurchase of excess capital stock in future quarters.

~~Hurricanes Harvey and Irma.~~ During the third quarter of 2017, two significant hurricanes struck the southeastern coast of the United States. On August 25, 2017, Hurricane Harvey made landfall near Corpus Christi, Texas, causing substantial damage and flooding to southeastern Texas, including the Houston metropolitan area. On September 10, 2017, Hurricane Irma made landfall on the Florida mainland near Marco Island, Florida. Hurricane Irma then moved northward through Florida and into Georgia, causing significant damage to property in Florida, Georgia, and certain other southeastern states.

The Bank has analyzed the potential impact that damage related to Hurricanes Irma and Harvey might have on the Bank’s advances, letters of credit, mortgage loans, and PLRMBS securities. Based on the information currently available, the Bank does not expect that the potential losses resulting from the hurricanes will have a material effect on the Bank’s financial condition or results of operations. The Bank continues to evaluate the impact of the hurricanes on its advances, letters of credit, mortgage loans held for portfolio, and PLRMBS investments. If additional information becomes available indicating that any of these assets have been impaired and the amount of the loss can be reasonably estimated, the Bank will record appropriate reserves at that time.

As provided by the FHLBank Act or regulations governing the operations of the FHLBanks, all of the FHLBanks have joint and several liability for FHLBank consolidated obligations, which are backed only by the financial resources of the FHLBanks. The joint and several liability regulation authorizes the Federal Housing Finance Agency (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 ~~September~~June 30, ~~2017~~2018, 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 all FHLBanks at the dates indicated was as follows:

(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,~~investments. This includes net accretion of related income, which is a result of improvement in expected cash flows on certain other-than-temporarily-impaired PLRMBS, less interest paid on consolidated obligations, deposits, mandatorily redeemable capital stock, and other borrowings. The Average Balance Sheets tables that follow 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 ~~nine~~six months ended ~~September~~June 30, ~~2017~~2018 and ~~2016,~~2017, together with the related interest income and expense. They also present the average rates on total interest-earning assets and the average costs of total funding sources.

estimated cash flows on a regular basis. If there is no additional impairment 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 accretion of yield adjustments 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–~~Statements – Note 16 – Fair Value.”

For securities previously identified as other-than-temporarily impaired, the Bank updates its estimate of future estimated cash flows on a regular basis. If there is no additional impairment 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 accretion of yield adjustments is likely to continue to be a positive source of net interest income in future periods.

expense of ~~$22~~$25 million resulting from net settlements on derivative instruments used in economic hedges in the first ~~nine~~six months of ~~2017~~2018 and ~~2016,~~2017, 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–~~Statements – Note 15 – Derivatives and Hedging Activities.”

Gains on Litigation Settlements, Net – During the first ~~nine~~six months of 2017, ~~and 2016,~~gains relating to settlements with certain defendants in connection with the Bank’s PLRMBS litigation (after netting certain legal fees and expenses) totaled $119 ~~million and $451 million, respectively.~~million.

Return on Average Equity

Return on average equity (ROE) was ~~5.19%~~6.31% (annualized) for the ~~third~~second quarter of 2018, compared to 5.56% (annualized) for the second quarter of 2017. The increase primarily reflected higher net income for the second quarter of 2018, which increased 30%, from $80 million in the second quarter of 2017 ~~compared~~ to ~~21.05%~~$104 million in the second quarter of 2018.

Dividends and Retained Earnings

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 restricted retained earnings, dividend payments, and the repurchase of excess capital stock. As required by the regulations governing the operations of the FHLBanks, the Framework is reviewed at least annually by the Bank’s Board of Directors. The Board of Directors may amend the Framework from time to time.

In accordance with the Framework, the Bank retains certain amounts in restricted retained earnings, which are not made available for dividends in the current dividend ~~period.~~period, and maintains an amount of total retained earnings at least equal to its required retained earnings as described in the Framework. The Bank may be restricted from paying dividends if it

~~Table of Contents~~

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 obligation 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 regulations.

The regulatory liquidity requirements state that each FHLBank must: (i) maintain eligible high quality assets (advances with a maturity not exceeding five years, U.S. Treasury securities investments, and deposits in banks or trust companies) in an amount equal to or greater than the deposits received from members, and (ii) hold contingent liquidity in an amount sufficient to meet its liquidity needs for at least five business days without access to the consolidated obligations markets. At ~~September~~June 30, ~~2017,~~2018, advances maturing within five years totaled ~~$60.6~~$69.5 billion, significantly in excess of the ~~$140~~$379 million of member deposits on that date. At December 31, ~~2016,~~2017, advances maturing within five years totaled ~~$48.4~~$76.6 billion, significantly in excess of the ~~$169~~$281 million of member deposits on that date.

As of ~~September~~June 30, ~~2017,~~2018, and December 31, ~~2016,~~2017, the Bank held estimated total sources of funds in an amount that would have allowed the Bank to meet its liquidity needs for more than five consecutive business days without issuing new consolidated obligations, subject to certain conditions. For more information, see “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations – Risk Management – Liquidity Risk” in the Bank’s ~~2016~~2017 Form 10-K.

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. As of ~~September~~June 30, ~~2017,~~2018, the Bank’s excess capital stock totaled ~~$452~~$152 million, or ~~0.41%~~0.14% of total assets.

In January 2017, the Framework was amended and approved by the Bank’s Board of Directors to include 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 Bank’s historical dividend rates and the dividend philosophy are not indicative of future dividend declarations. The Bank’s dividend policy may be revised or eliminated in the future and there can be no assurance as to future dividends.

In the ~~third~~second quarter of 2018, the Bank paid dividends at an annualized rate of 7.00%, totaling $63 million, including $58 million in dividends on capital stock and $5 million in dividends on mandatorily redeemable capital stock. In the second quarter of 2017, the Bank paid dividends at an annualized rate of 7.00%, totaling ~~$51~~$48 million, including ~~$44~~$41 million in dividends on capital stock and $7 million in dividends on mandatorily redeemable capital stock.

In the ~~third quarter~~first six months of ~~2016,~~2018, the Bank paid dividends at an annualized rate of ~~9.17%~~7.00%, totaling ~~$63~~$122 million, including ~~$52~~$111 million in dividends on capital stock and $11 million in dividends on mandatorily redeemable capital stock.

In the first ~~nine~~six months of 2017, the Bank paid dividends at an annualized rate of ~~7.69%~~8.04%, totaling ~~$164~~$113 million, including ~~$139~~$95 million in dividends on capital stock and $25 million in dividends on mandatorily redeemable capital stock. In the first nine months of 2016, the Bank paid dividends at an annualized rate of 8.70%, totaling $179 million, including $146 million in dividends on capital stock and $33$18 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.

In January 2017, the Framework was amended and approved by the Bank’s Board of Directors to include a dividend philosophy to endeavor to pay a quarterly dividend at an annualized rate between 5% and 7%, which was intended to be considered by the Bank’s Board of Directors beginning with the Bank’s second quarter 2017 dividend declaration. 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.

On ~~October~~July 26, ~~2017,~~2018, the Bank’s Board of Directors declared a cash dividend on the capital stock outstanding during the ~~third~~second quarter of ~~2017~~2018 at an annualized rate of 7.00%, totaling ~~$55~~$56 million, including ~~$48~~$51 million in dividends on capital stock and $7$5 million in dividends on mandatorily redeemable capital stock.

option. The overall increase in the unrealized losses on the hedged advances and advances carried at fair value from December 31, ~~2016,~~2017, to ~~September~~June 30, ~~2017,~~2018, 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.

carried at fair value from December 31, ~~2016,~~2017, to ~~September~~June 30, ~~2017,~~2018, were primarily attributable to 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 Bank's consolidated obligation bonds 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 ~~September~~June 30, ~~2017,~~2018, 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 ~~$1,028.7~~$1,059.9 billion at ~~September~~June 30, ~~2017,~~2018, and ~~$989.3~~$1,034.3 billion at December 31, ~~2016.~~2017.

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.

The Bank ~~evaluated the publicly disclosed FHLBank regulatory actions and long-term credit ratings of the other FHLBanks as of September 30, 2017, and as of each period end presented, and~~ does not believe, as of the date of this report, that it is probable that the Bank will be required to repay any principal or interest associated with consolidated obligations for which the Bank is not the primary obligor.

includes income and expense associated with net settlements from economic hedges that are recorded in “Net gain/(loss) on derivatives and hedging activities” in other income and excludes interest expense that is recorded in “Mandatorily redeemable capital stock.” Other key financial information, such as any credit-related OTTI losses on the Bank’s PLRMBS, other expenses, and assessments, is not included in the segment reporting analysis, but is 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 14 – Segment Information.”

Advances-Related Business. The advances-related business consists of advances and other credit products, related financing and hedging instruments, ~~and~~ liquidity and other non-MBS investments associated with the Bank’s role as a liquidity provider, and capital. Assets associated with this segment ~~increased $16.3~~decreased $16.6 billion to ~~$90.3~~$86.8 billion (82% of total assets) at ~~September~~June 30, ~~2017~~2018, from ~~$74.0~~$103.4 billion ~~(81%~~(84% of total assets) at December 31, ~~2016~~2017.

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 on capital.

Adjusted net interest income for this segment was ~~$62~~$79 million in the ~~third~~second quarter of ~~2017~~2018, an increase of ~~$20~~$22 million, or ~~48%~~39%, compared to ~~$42~~$57 million in the ~~third~~second quarter of ~~2016~~2017. In the first ~~nine~~six months of ~~2017~~2018, adjusted net interest income for this segment was ~~$167~~$157 million, an increase of $52 million, or ~~45%~~50%, compared to $~~115~~105 million in the first ~~nine~~six months of ~~2016~~2017. The increase was primarily due to an improvement in spreads and higher balances on advances-related assets, ~~and higher earnings from an increase in spreads on non-MBS investments,~~ partially offset by lower earnings from ~~advance prepayment fees.~~non-MBS investments.

Table of Contents

Adjusted net interest income for this segment represented ~~43%~~52% and ~~33%~~41% of total adjusted net interest income for the ~~third~~second quarter of 2018 and 2017, and ~~2016~~,51% and ~~40%~~ ~~and 31%~~39% of total adjusted net interest income for the first ~~nine~~six months of ~~2017~~2018 and ~~2016~~2017, respectively.

~~Members and nonmember borrowers prepaid $3.0 billion of advances in the third quarter of~~ ~~2017~~ ~~compared to $896 million in the third quarter of~~ ~~2016. Interest income was increased by net prepayment fees of $1 million and $3 million in the third quarter of 2017 and 2016, respectively. Members and nonmember borrowers prepaid~~ ~~$6.0 billion~~ ~~of advances in the first nine months of~~ ~~2017~~ ~~compared to~~ ~~$2.8 billion~~ ~~in the first nine months of~~ ~~2016. Interest income was increased by net prepayment fees of $1 million in the first nine months of 2017 and $5 million in the first nine months of 2016.~~

Advances – The par value of advances outstanding ~~increased~~decreased by ~~$11.9~~$6.9 billion, or ~~24%~~9%, to ~~$61.7~~$70.6 billion at ~~September~~June 30, ~~2017,~~2018, from ~~$49.8~~$77.5 billion at December 31, ~~2016.~~2017. Average advances outstanding were ~~$71.2~~$71.8 billion in the ~~third~~second quarter of ~~2017~~2018, a 9% increase from ~~$65.6~~$65.8 billion in the ~~third~~second quarter of ~~2016~~2017.

Outstanding balances of advances may significantly increase and decrease from period to period because of a member’s liquidity and financial strategies.

As of ~~September~~June 30, ~~2017,~~2018, advances outstanding to the Bank’s top five borrowers and their affiliates ~~increased~~decreased by ~~$6.6~~$3.9 billion, and advances outstanding to the Bank’s other borrowers ~~increased~~decreased by ~~$5.3~~$3.0 billion. Advances to the top five borrowers ~~increased~~decreased to ~~$39.0~~$44.5 billion at ~~September~~June 30, ~~2017,~~2018, from ~~$32.4~~$48.4 billion at December 31, ~~2016.~~2017. (See “Item 1. Financial Statements – Note 87 – ~~Advances–~~Advances – Credit and Concentration Risk” for further information.)

The ~~$11.9~~$6.9 billion ~~increase~~decrease in advances outstanding ~~primarily~~ reflected a ~~$11.5~~$4.3 billion ~~increase~~decrease in fixed rate advances, ~~and~~ a ~~$1.1 billion increase in adjustable rate advances, partially offset by a $0.7~~$1.4 billion decrease in variable rate advances, and a $1.2 billion decrease in adjustable rate advances.

Partial prepayment symmetry (PPS) is a product feature under which 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. Any prepayment credit on an advance with PPS would be limited to the lesser of 10% of the par value of the advance or the gain recognized on the termination of the associated interest rate swap, which may also include a similar contractual gain limitation.

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 ~~$28.4~~$16.1 billion and ~~$23.9~~$25.7 billion as of ~~September~~June 30, ~~2017~~2018, and December 31, ~~2016~~2017, respectively. The ~~increase~~decrease in the total size of the non-MBS investment portfolio reflects ~~higher balances of Federal funds sold, partially offset by~~ lower balances of securities purchased under agreements to resell, agency securities, and ~~certificates of deposit.~~Federal funds sold.

Interest rate payment terms for non-MBS investments classified as HTM at ~~September~~June 30, ~~2017~~2018, and December 31, ~~2016~~2017, are detailed in the following table:

Borrowings – Total liabilities (primarily consolidated obligations) funding the advances-related business ~~increased~~decreased to ~~$83.9~~$80.4 billion at ~~September~~June 30, ~~2017~~2018, from $~~68.5~~96.6 billion at December 31, ~~2016~~2017. 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 17 – 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 consolidated obligation bonds are issued on behalf of the Bank, typically the Bank simultaneously enters into interest rate exchange agreements with features that offset the complex features of the bonds and, in effect, convert the bonds to adjustable rate ~~instruments tied to an index, primarily LIBOR.~~instruments. For example, the Bank uses fixed rate callable bonds that are typically offset with interest rate exchange agreements with call features that offset the call options embedded in the callable bonds. This combined financing structure enables the Bank to meet its funding needs at costs not generally attainable solely through the issuance of comparable term non-callable debt.

At ~~September~~June 30, ~~2017~~2018, the notional amount of interest rate exchange agreements associated with the advances-related business totaled $~~53.7~~70.8 billion, of which $~~29.5~~38.4 billion were hedging advances, $~~23.4~~31.8 billion were hedging consolidated obligations, $~~0.7~~0.5 billion were economically hedging trading securities, and $0.1 billion were offsetting derivatives. At December 31, ~~2016~~2017, the notional amount of interest rate exchange agreements associated with the advances-related business totaled $~~59.4~~95.5 billion, of which $~~18.7~~44.3 billion were hedging advances, $~~39.9~~50.4 billion were hedging consolidated obligations, $~~0.7~~0.8 billion were economically hedging trading securities, and ~~$0.1 billion~~$14 million were offsetting derivatives. The hedges associated with advances and consolidated obligations were primarily used to convert the fixed rate cash flows ~~and non-LIBOR-indexed cash flows~~ of the advances and consolidated obligations to adjustable rate ~~LIBOR-indexed~~ 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.

Mortgage-Related Business. The mortgage-related business consists of MBS investments, mortgage loans acquired through the Mortgage Partnership ~~Finance (MPF)~~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 and mortgage loans and the cost of the consolidated obligations funding those assets, including the net settlements from associated interest rate exchange agreements.

At ~~September~~June 30, ~~2017~~2018, assets associated with this segment were $~~19.2~~19.4 billion (18% of total assets), ~~an increase~~a decrease of $~~1.3~~0.6 billion from $~~17.9~~20.0 billion at December 31, ~~2016~~2017 (~~19%~~16% of total assets).

Adjusted net interest income for this segment was ~~$82~~$73 million in the ~~third~~second quarter of ~~2017~~2018, a decrease of $2$8 million, or 2%10%, from ~~$84~~$81 million in the ~~third~~second quarter of ~~2016~~2017. In the first ~~nine~~six months of ~~2017~~2018, adjusted net interest income for this segment was $~~246~~148 million, a decrease of $816 million, or 3%10%, from $~~254~~164 million in the first ~~nine~~six months of ~~2016~~2017. The decrease in adjusted net interest income was ~~primarily~~ due to ~~a decrease in accretion of yield adjustments on certain other-than-temporarily impaired PLRMBS, resulting from improvement in expected cash flows. Earnings from~~ lower spreads ~~were largely~~on interest-earning assets, primarily caused by lower spreads on new investments, and lower accretion-related income, which more than offset bythe impact of higher average balances onof MBS investments and mortgage loans.

Adjusted net interest income for this segment represented ~~57%~~48% and ~~67%~~59% of total adjusted net interest income for the ~~third~~second quarter of 2018 and 2017, and ~~2016,~~49% and ~~60%~~ ~~and 69%~~61% of total adjusted net interest income for the first ~~nine~~six months of 2018 and 2017, ~~and 2016,~~ respectively.

MBS Investments – The Bank’s MBS portfolio was $~~17.4~~16.6 billion at ~~September~~June 30, ~~2017~~2018, compared with $~~17.0~~17.8 billion at December 31, ~~2016~~2017. During the first ~~nine~~six months of ~~2017,~~2018, the Bank’s MBS portfolio ~~increased~~decreased primarily because of ~~$3.4~~$1.9 billion in principal repayments, partially offset by $0.6 billion in new MBS ~~investments, partially offset by $3.1 billion in principal repayments.~~investments. Average MBS investments were ~~$16.8~~$16.6 billion in the ~~third~~second quarter of ~~2017,~~2018, an increase of ~~$1.1~~$0.4 billion from ~~$15.7~~$16.2 billion in the ~~third~~second quarter of ~~2016.~~2017. Average MBS investments were ~~$16.4~~$16.9 billion in the first ~~nine~~six months of ~~2017~~2018, an increase of ~~$1.0~~$0.7 billion from ~~$15.4~~$16.2 billion in the first ~~nine~~six months of ~~2016.~~2017.

Intermediate-term and long-term fixed rate MBS investments are subject to prepayment risk, and intermediate-term and long-term adjustable rate MBS investments are also subject to interest rate cap risk. The Bank has managed these risks predominately by purchasing intermediate-term fixed rate MBS (rather than long-term fixed rate MBS), funding the fixed rate MBS with a mix of non-callable and callable debt, and using interest rate exchange agreements with interest rate risk characteristics similar to callable debt. The Bank has purchased interest rate caps to hedge some of the interest rate cap risk associated with the long-term adjustable rate MBS investments.

Interest rate payment terms for MBS securities at ~~September~~June 30, ~~2017~~2018, and December 31, ~~2016~~2017, are shown in the following table:

MPF Program – Under the MPF Program, the Bank may purchase from members, for its own portfolio, conventional conforming fixed rate mortgage loans under the MPF Original product and mortgage loans insured by the Federal Housing Administration (FHA) or guaranteed by the Department of Veterans Affairs (VA) under the MPF Government product. In addition, the Bank may facilitate the purchase of conforming fixed rate mortgage loans from members for concurrent sale to Fannie Mae under the MPF Xtra product; of jumbo fixed rate mortgage loans for concurrent sale to Redwood Residential Acquisition Corporation, a subsidiary of Redwood Trust, Inc., a real estate investment trust, under the MPF Direct product; and of government-insured or government-guaranteed mortgage loans that will be packaged into securities backed by the mortgage loans and guaranteed by Ginnie Mae under the MPF Government MBS product. When members sell mortgage loans under the MPF Xtra, MPF Direct, and MPF Government MBS products, the loans are sold to a third-party investor and are not recorded on the Bank’s Statements of Condition.

As of ~~September~~June 30, ~~2017~~2018, all mortgage loans purchased by the Bank under the MPF Program were qualifying conventional conforming fixed rate, first lien mortgage loans with fully amortizing loan terms of up to 30 years. A conventional loan is one that is not insured by the federal government or any of its agencies. Conforming loan size, which is established annually as required by Finance Agency regulations, may not exceed the loan limits set by the

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 ~~interest rate~~market risks inherent in its ordinary course of business, including its lending, investment, and funding activities. For more information on 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 – Market Risk – Interest Rate

Exchange Agreements” in the Bank’s ~~2016~~2017 Form 10-K.

The following table summarizes 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 as of ~~September~~June 30, ~~2017~~2018, and December 31, ~~2016~~2017.

Liquidity and Capital Resources

The Bank’s financial strategies are designed to enable the Bank to safely 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 strives 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 in order to maintain ready access to sufficient liquid funds to

meet normal transaction requirements, take advantage of appropriate investment opportunities, and cover

unforeseen liquidity demands.

The Bank generally manages operational, contingent, and structural liquidity 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 Bank maintains short-term, high-quality money market investments and government and agency securities in amounts that may average up to three times the Bank’s capital as a primary source of funds to satisfy these requirements and objectives.

The Bank has a regulatory contingent liquidity requirement to maintain at least 5 business days of liquidity to enable it to meet its obligations without issuance of new consolidated obligations. In addition, the Finance Agency has established liquidity guidelinesthatrequire each FHLBank to maintain sufficient on-balance sheet liquidity in an amount at least equal to its anticipated cash outflows for two different scenarios. Both scenarios assume no new consolidated obligation issuance and no reliance on repurchase agreements and permit the sale of certain existing investments as determined by the Finance Agency. The two scenarios differ only in the treatment of maturing advances. One scenario assumes that the Bank does not renew any maturing advances. For this scenario, the Bank must have sufficient liquidity to meet its obligations for 15 calendar days. The second scenario requires the Bank to renew maturing advances for certain members based on specific criteria established by the Finance Agency. For this scenario, the Bank must have sufficient liquidity to meet its obligations for 5 calendar days.

In addition to the regulatory contingent liquidity requirement and 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).

The Bank actively monitors and manages structural liquidity risks, which the Bank defines as maturity mismatches greater than 90 days for sources and uses of funds, of the advances business segment. Structural liquidity maturity mismatches are identified using maturity gap analysis and valuation sensitivity metrics that quantify the risk associated with the Bank’s structural liquidity position.

The following table shows the Bank’s principal financial obligations due, estimated sources of funds available to meet those obligations, and the net difference between funds available and funds needed for the 5-business-day period following ~~September~~June 30, ~~2017,~~2018, and December 31, ~~2016.~~2017.

Regulatory Capital Requirements

The FHLBank Act and Finance Agency regulations specify that each FHLBank must meet certain minimum regulatory capital standards. 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. 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 following table shows the Bank’s compliance with the Finance Agency’s capital requirements at ~~September~~June 30, ~~2017~~2018, and December 31, ~~2016~~2017. ~~The Bank’s risk-based capital requirement decreased to $2.0 billion at~~ ~~September 30, 2017, from $2.2 billion at~~ ~~December 31, 2016~~.

The Bank repurchased ~~$331~~$1,128 million in excess capital stock during the first ~~nine~~six months of ~~2017.~~2018. As a result of ~~recent~~ changes in the Bank’s capital plan, both capital stock and retained earnings are required to support regulatory capital compliance.

~~In accordance with its~~On April 9, 2018, the Bank’s Board of Directors revised the Framework to change the Bank’s practice ~~the Bank plans to repurchase~~of repurchasing the surplus capital stock of all members and the excess

capital stock of all ~~nonmember shareholders~~former members from a quarterly schedule to a daily schedule. Surplus capital stock is defined as any stock holdings in excess of 115% of a member’s minimum stock requirement. Effective April 24, 2018, the Bank began calculating the amount of stock to be repurchased each business day based on ~~November 14, 2017~~.the shareholder’s capital stock outstanding after all stock transactions are completed for the day, ensuring that each member and former member will continue to meet its minimum capital stock requirement after the repurchase. In accordance with the revised Framework, the Bank repurchased $363 million of excess capital stock on April 24, 2018. The Bank may change this practice at any time. All repurchases of capital stock are at the Bank’s discretion, subject to certain statutory and regulatory requirements and to the Bank’s Risk Management Policy, Capital Plan, and the Framework.

The Bank’s capital requirements are more fully discussed in “Item 8. Financial Statements and Supplementary Data – Note 15 – Capital” in the Bank’s ~~2016 Form~~2017 10-K.

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

Table of Contents

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 ~~2016~~2017 Form 10-K.

~~Table of Contents~~

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.

The Bank determines the maximum amount and maximum term of the advances it will make to a member or housing associate based on the institution’s creditworthiness and eligible collateral pledged in accordance with the Bank’s credit and collateral policies and regulatory requirements. The Bank may review and change the maximum amount and maximum term at any time. The maximum amount a member or housing associate may borrow is also limited by the amount and type of collateral pledged because all advances must be fully collateralized.

To identify the credit strength of each borrower and potential borrower, other than insurance companies, community development financial institutions (CDFIs), and housing associates, the Bank assigns each member and each nonmember borrower an internal credit quality rating from one to ten, with one as the highest credit quality rating. These ratings are based on results from the Bank’s credit model, which considers financial, regulatory, and other qualitative information, including regulatory examination reports. The internal ratings are reviewed on an ongoing basis using current available information and are revised, if necessary, to reflect the institution’s current financial position. Credit and collateral terms may be adjusted based on the results of this credit analysis.

The Bank determines the maximum amount and maximum term of the advances it will make to an insurance company based on an ongoing risk assessment that considers the member's financial and regulatory standing and other qualitative information deemed relevant by the Bank. This evaluation results in the assignment of an internal credit quality rating from one to ten, with one as the highest credit quality rating. Approved terms are designed to meet the needs of the individual member while mitigating the unique credit and collateral risks associated with insurance companies, including risks related to the resolution process for insurance companies, which is significantly different from the resolution processes established for the Bank’s insured depository members.

The Bank determines the maximum amount and maximum term of the advances it will make to a CDFI based on an ongoing risk assessment that considers information from the CDFI’s audited annual financial statements, supplemented by additional information deemed relevant by the Bank. Approved terms are designed to meet the needs of the individual member while mitigating the unique credit and collateral risks of CDFIs, which do not file quarterly regulatory financial reports and are not subject to the same inspection and regulation requirements as the Bank’s insured depository members.

The Bank determines the maximum amount and maximum term of the advances it will make to a housing associate based on an ongoing risk assessment that considers the housing associate’s financial and regulatory standing and other qualitative information deemed relevant by the Bank. Approved terms are designed to meet the needs of the individual housing associate while mitigating the unique credit and collateral risks of housing associates, which do not file quarterly regulatory financial reports and are not subject to the same inspection and regulation requirements as the Bank’s insured depository members.

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. 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

~~Table of Contents~~

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. The Bank monitors each borrower’s aggregate borrowing capacity and collateral requirements on a daily basis by comparing the institution’s borrowing capacity to its obligations to the Bank.

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 housing associate’s assets. 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 ~~September~~June 30, ~~2017~~2018, and December 31, ~~2016~~2017. During the ~~nine~~six months ended ~~September~~June 30, ~~2017~~2018, the Bank’s internal credit ratings stayed the same or improved for the majority of members and nonmember borrowers.

(1)	Includes advances, letters of credit, the market value of swaps, estimated prepayment fees for certain borrowers, and the credit enhancement obligation on MPF loans.


(2)	Collateral borrowing capacity does not represent any commitment to lend on the part of the Bank.

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’ pricing volatility and market liquidity risks. Securities are delivered to the Bank’s custodian when they are pledged. The Bank prices securities collateral on a daily basis or twice a month, depending on the availability and reliability of external pricing sources. Securities that are normally priced twice a month may be priced more frequently in volatile market conditions. The Bank benchmarks the borrowing capacities for securities collateral to the market on a periodic basis and may review and change the borrowing capacity for any security type at any time. As of ~~September~~June 30, ~~2017~~2018, the

value. The borrowing capacities assigned to private-label MBS, which must be rated AAA or AA when initially pledged, generally ranged from 65% to ~~85%~~90% of their market value, depending on the underlying collateral (residential mortgage loans, home equity loans, or commercial real estate loans), the rating, and the subordination structure of the respective securities.

The following table presents the securities collateral pledged by all members and by nonmembers with credit outstanding at ~~September~~June 30, ~~2017~~2018, and December 31, ~~2016~~2017.

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 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. With a blanket lien, a borrower generally pledges the following loan types, whether or not the individual loans are eligible to receive borrowing capacity: all loans secured by real estate; all loans made for commercial, corporate, or business purposes; and all participations in these loans. Borrowers pledging under a blanket lien may provide a detailed listing of loans or may use a summary reporting method.

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. With the exception of insurance companies, CDFIs, and housing associates, borrowers required to deliver loan collateral must pledge those loans under a blanket lien with detailed reporting.

As of ~~September~~June 30, ~~2017~~2018, of the loan collateral pledged to the Bank, 25% was pledged by 2726 institutions by specific identification, ~~51%~~50% was pledged by ~~124~~125 institutions under a blanket lien with detailed reporting, and ~~24%~~25% was pledged by ~~128~~126 institutions under a blanket lien with summary reporting.

As of ~~September~~June 30, ~~2017~~2018, 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: 90% for first lien residential mortgage loans, 88% for multifamily mortgage loans, 88% for commercial mortgage loans, and 77% 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

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.

(1)	The unpaid principal balance for loan participations is 100% of the outstanding loan amount. The borrowing capacity for loan participations is based on the participated amount pledged to the Bank.

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 ~~September~~June 30, ~~2017~~2018, and December 31, ~~2016~~2017, the unpaid principal balance of these loans totaled $109 billion and $9 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 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 best estimate of the present value of the cash flows expected to be collected from the security with the amortized cost basis of the security. If the Bank’s best estimate of the present value of the cash flows expected 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 the decline is other than temporary. The Bank recognizes an OTTI 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

Table of Contents

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 comparable Fitch Ratings (Fitch) ratings.

(1)	Credit ratings of BB and lower are below investment grade.


(2)	The Bank has one security guaranteed by Fannie Mae but rated D by S&P because of extraordinary expenses incurred during bankruptcy of the security's sponsor.


(3)	Includes ~~$135~~$146 million and ~~$130~~$225 million at ~~September~~June 30, ~~2017,~~2018, and December 31, ~~2016,~~2017, respectively, in Federal funds sold to a member counterparty determined by the Bank to have an internal credit rating equivalent to an AA rating.

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, securities purchased under agreements to resell, and negotiable certificates of deposit 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. This limit is calculated with reference to a percentage of either the FHLBank’s or the counterparty’s capital and to the counterparty’s overall credit rating. Under these regulations, the lesser of the FHLBank’s total regulatory capital or the counterparty’s Tier 1 capital is multiplied by a percentage specified in the regulation. The percentages used to determine the maximum amount of term extensions of unsecured credit range from 1% to 15%, depending on the counterparty’s overall credit rating. Term extensions of unsecured credit include on-balance sheet transactions, off-balance sheet commitments, and derivative transactions, but exclude overnight Federal funds sales, even if subject to a continuing contract. (See “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Risk Management – Derivative Counterparties” for additional information related to derivatives exposure.)

Finance Agency regulations also permit the FHLBanks to extend additional unsecured credit to the same single counterparty for overnight sales of Federal funds, even if subject to a continuing contract. However, an FHLBank’s total unsecured credit to a single counterparty (total term plus additional overnight Federal funds unsecured credit) may not exceed twice the regulatory limit for term exposures (2% to 30% of the lesser of the FHLBank’s total regulatory capital or the counterparty’s Tier 1 capital, based on the counterparty’s overall credit rating). 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.

(1)	Excludes unsecured investment credit exposure to U.S. government agencies and instrumentalities, government-sponsored enterprises, and supranational entities and does not include related accrued interest as of ~~September~~June 30, ~~2017~~2018.

The Bank’s investments may also include housing finance agency bonds issued by housing finance agencies located in Arizona, California, and Nevada, the three states that make up the Bank’s district. These bonds are federally taxable mortgage revenue bonds, collateralized by pools of first lien residential mortgage loans and credit-enhanced by bond insurance. The bonds held by the Bank are issued by the California Housing Finance Agency (CalHFA) and insured by either National Public Financial Guarantee (formerly MBIA Insurance Corporation), or Assured Guaranty Municipal Corporation (formerly Financial Security Assurance Incorporated). At ~~September~~June 30, ~~2017~~2018, all of the bonds were rated at least A by Moody’s or S&P.

For the Bank’s investments in housing finance agency bonds, which were issued by CalHFA, the gross unrealized losses were mainly due to an illiquid market, credit concerns regarding the underlying mortgage collateral, and credit concerns regarding the monoline insurance providers, causing these investments to be valued at a discount to their acquisition cost. The Bank independently modeled cash flows for the underlying collateral, using assumptions for default rates and loss severity that a market participant would deem reasonable, and concluded that the available credit support within the CalHFA structure more than offset the projected underlying collateral losses. The Bank determined that, as of ~~September~~June 30, ~~2017~~2018, all of the gross unrealized losses on the CalHFA bonds are temporary because the underlying collateral and credit enhancements were sufficient to protect the Bank from losses. As a result, the Bank expects to recover the entire amortized cost basis of these securities. If conditions in the housing and mortgage markets and general business and economic conditions deteriorate, the fair value of the CalHFA bonds may decline further and the Bank may experience OTTI in future periods.

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 to three times the Bank’s capital at the time of purchase. At ~~September~~June 30, ~~2017~~2018, the Bank’s MBS

9795

Table of Contents

~~Bank’s MBS~~ portfolio was ~~268%~~253% of Bank capital (as determined in accordance with regulations governing the operations of the FHLBanks). The Bank has not purchased any PLRMBS since the first quarter of 2008.

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 ~~September~~June 30, ~~2017~~2018, PLRMBS representing ~~21%~~19% 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 ~~September~~June 30, ~~2017~~2018, the Bank’s investment in MBS had gross unrealized losses totaling $6197 million, ~~most~~$31 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 ~~September~~June 30, ~~2017~~2018, all of the gross unrealized losses on its agency MBS are temporary.

To assess whether it expects to recover the entire amortized cost basis of its PLRMBS, the Bank performed a cash flow analysis for all of its PLRMBS as of ~~September~~June 30, ~~2017~~,2018, using two third-party models. The ~~first model projects prepayments, default rates, and loss severities on~~FHLBanks’ OTTI Committee developed a short-term housing price forecast with projected changes ranging from a decrease of 8.0% to an increase of 13.0% over the ~~underlying collateral based on borrower characteristics and~~12-month period beginning April 1, 2018. For the ~~particular attributes~~vast majority of markets, the ~~loans underlying the Bank’s securities, in conjunction with assumptions related primarily to future changes in housing prices and interest rates.~~ A ~~significant input to the first model is the forecast of future~~projected short-term housing price changes range from an increase of 2.0% to an increase of 7.0%. Thereafter, a unique path is projected for ~~the relevant states and core-based statistical areas (CBSAs), which are~~each geographic area based on an assessment of the regional housing markets. CBSA refers collectively to metropolitan and micropolitan statistical areas as defined by the U.S. Office of Management and Budget. As currently defined, a CBSA must contain at least one urban area with a population of 10,000 or more people.

~~The month-by-month projections of future loan performance~~internally developed framework derived from the first model, which reflect projected prepayments, default rates, and loss severities, are then input into a second model that allocates the projected loan level cash flows and losses to the various security classes in each securitization structure in accordance with the structure’s prescribed cash flow and loss allocation rules. When the credit enhancement for the senior securities in a securitization is derived from the presence of subordinated securities, losses are generally allocated first to the subordinated securities until their principal balance is reduced to zero. historical data.

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 assumptions and expectations. The scenario of cash flows determined ~~based on the model approach described above~~ reflects a best-estimate scenario and includes a base case housing price forecast that reflects the expectations for near- and long-term housing price behavior.

The FHLBanks’ OTTI Committee developed a short-term housing price forecast with projected changes ranging from a decrease of 6.0% to an increase of 13.0% over the 12-month period beginning July 1, 2017. For the vast majority of markets, the projected short-term housing price changes range from an increase of 1.0% to an increase of 6.0%. Thereafter, a unique path is projected for each geographic area based on an internally developed framework derived from historical data.

In addition to evaluating its PLRMBS under a base case (or best estimate) scenario, the Bank performed a cash flow analysis for each of these securities under a more adverse housing price scenario. This more adverse scenario was

primarily based on a short-term housing price forecast that was five percentage points below the base case forecast, followed by a recovery path with annual rates of housing price growth that were 33.0% lower than the base case.

The following table shows the base case scenario and what the credit-related OTTI loss would have been under the more adverse housing price scenario at ~~September~~June 30, ~~2017~~:2018:

(1)	The credit ratings used by the Bank are based on the lowest of Moody’s, S&P, or comparable Fitch ratings. Credit ratings of BB and lower are below investment grade.

For the Bank’s PLRMBS, the following table shows the amortized cost, estimated fair value, credit- and non-credit-related OTTI, performance of the underlying collateral based on the classification at the time of origination, and credit enhancement statistics by type of collateral and year of securitization. Credit enhancement is defined as the percentage of subordinated tranches and over-collateralization, if any, in a security structure that will absorb losses before the Bank will experience a loss on the security, expressed as a percentage of the underlying collateral balance. The credit enhancement figures include the additional credit enhancement required by the Bank (above the amounts required for an AAA rating by the credit rating agencies) for selected securities starting in late 2004, and for all securities starting in late 2005. The calculated weighted averages represent the dollar-weighted averages of all the PLRMBS in each category shown. The classification (prime or Alt-A) is based on the model used to run the estimated cash flows for the security, which may not necessarily be the same as the classification at the time of origination.

Credit enhancement is defined as the subordinated tranches and over-collateralization, if any, in a security structure that will generally absorb losses before the Bank will experience a loss on the security, expressed as a percentage of the underlying collateral balance. The calculated averages represent the dollar-weighted averages of all the PLRMBS investments in each category shown. The classification (prime or Alt-A) is based on the model used to run the estimated cash flows for the security, which may not necessarily be the same as the classification at the time of origination.

The following table presents the fair value of the Bank’s PLRMBS as a percentage of the unpaid principal balance by collateral type at origination and year of securitization.

The Bank determined that, as of ~~September~~June 30, ~~2017~~2018, the gross unrealized losses on the PLRMBS that have not had an OTTI loss are primarily due to illiquidity in the PLRMBS 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. The Bank does not intend to sell these securities, it is not more likely than not that the Bank will be required to sell these securities before its anticipated recovery of the remaining amortized cost basis, and the Bank expects to recover the entire amortized cost basis of these securities. As a result, the Bank determined that, as of ~~September~~June 30, ~~2017~~2018, all of the gross unrealized losses on these securities are temporary. The Bank will continue to monitor and analyze the performance of these securities to assess the likelihood of the recovery of the entire amortized cost basis of these securities as of each balance sheet date.

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 OTTI of additional PLRMBS in future periods, as well as further impairment of PLRMBS that were identified as other-than-temporarily impaired as of ~~September~~June 30, ~~2017~~2018. Additional future credit-related OTTI 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 additional credit-related OTTI losses on its PLRMBS in the future.

Derivative Counterparties. The Bank has also 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) 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

101

collateral at specified levels to limit the Bank’s

~~104~~

~~Table of Contents~~

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). All credit exposure from derivative transactions entered into by the Bank with member counterparties that are not derivative dealers (including interest rate swaps, caps, and floors), for which the Bank serves as an intermediary, must be fully secured by eligible collateral, and all such derivative transactions are subject to both the Bank’s Advances and Security Agreement and a master netting agreement.

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 ~~September~~June 30, ~~2017~~2018.

Cleared Derivatives. The Bank is subject to nonperformance by the derivatives clearing organizations (clearinghouses) and clearing agents. The requirement that the Bank post initial and variation margin through ~~the~~a clearing agent, to the clearinghouse, exposes the Bank to institutional credit risk in the event that the clearing agent or the clearinghouse fails to meet its obligations. ~~However, the~~The use of cleared derivatives, however, mitigates the Bank’s overall credit risk exposure because a central counterparty is substituted for individual ~~counterparties~~counterparties.

On May 31, 2017, S&P lowered the rating to A and withdrew the rating at LCH Group Holdings Limited’s request. LCH Ltd’s ultimate parent, London Stock Exchange Group, plc., is rated A3 by Moody’s and A- by S&P.

The increase or decrease in the credit exposure net of cash collateral, from one period to the next, may be affected by changes in several variables, such as the size and composition of the portfolio, market values of derivatives, and accrued interest.

Based on the master netting arrangements, its credit analyses, and the collateral requirements in place with each counterparty, the Bank does not expect to incur any credit losses on its derivative agreements.

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 operations significantly. Although the Bank believes these judgments, estimates, and assumptions to be reasonably accurate, actual results may differ.

In the Bank’s ~~2016~~2017 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: estimating the allowance for credit losses on the advances and mortgage loan portfolios; 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; accounting for ~~OTTI~~other-than-temporary impairment for investment securities; and estimating the prepayment speeds on MBS and mortgage loans for the accounting of amortization of premiums and accretion of discounts on MBS and mortgage loans.

~~FHLBank Capital Requirements.~~ ~~On July 3, 2017, the Finance Agency published a proposed rule to adopt, with amendments, the regulations~~Adoption of Single-Counterparty Credit Limits for Bank Holding Companies and Foreign Banking Organizations by Board of Governors of the Federal ~~Housing Finance~~Reserve System. On June 14, 2018, the Board ~~(predecessor to the Finance Agency) pertaining to the capital requirements for the FHLBanks.

The FHLBanks are exempt from the limits and reporting requirements contained in this rule, however, credit ~~risk component~~exposure to individual FHLBanks must be monitored, and reported on as required, by any entity that is a covered company under this rule.

Under the final rule, a covered company and its subsidiaries may not have aggregate net credit exposure to an FHLBank and, in certain cases, economically interdependent entities in excess of 25% of the ~~risk-based~~company’s Tier 1 capital. Such credit exposure does not include advances from an FHLBank but generally includes collateral pledged to an FHLBank in excess of a covered company’s outstanding advances. The following items are also included towards a covered company’s net credit exposure: its investment in FHLBank capital ~~requirement, as well as~~stock and consolidated obligations, deposits with an FHLBank, FHLBank-issued letters of credit where a covered company is the ~~limitations on extensions~~named beneficiary, and other obligations to an FHLBank, including repurchase or reverse repurchase transactions net of ~~unsecured credit.

The proposed rule also would revise the percentages used in the regulation’s tables to calculate credit risk capital charges for advances and for non-mortgage assets. The Finance Agency proposes to retain for now the percentages used in the tables to calculate capital charges for mortgage-related assets, and to address the methodology for residential mortgage assets at a later date. While a March 2009 regulatory directive pertaining to certain liquidity matters will continue to remain in place, the Finance Agency also proposes to rescind certain minimum regulatory liquidity requirements for the FHLBanks and address these liquidity requirements in a separate rulemaking.

~~FHLBank Membership for Non-Federally-Insured Credit Unions.~~Annual Designation of Member Director and Independent Director Positions. On June ~~5, 2017,~~6, 2018, the Finance Agency ~~issued a final rule~~designated one member director position for Arizona, six for California, and one for Nevada, effective July 5, 2017, governing FHLBank membership that would implement statutory amendments to the Federal Home Loan Bank Act authorizing FHLBanks to accept applications for membership from state-chartered credit unions without federal share insurance, provided that certain prerequisites have been met. The new rule generally treats these credit unionsJanuary 1, 2019, the same allocation of positions as ~~other depository institutions with an additional requirement that they obtain: (1) an affirmative statement from their state regulator that they meet the requirements~~ for federal insurance as of the date of their application for FHLBank membership; (2) a written statement from the state regulator that it cannot or will not make any determination regarding eligibility for federal insurance; or (3) if the regulator fails or refuses to respond to the credit union’s request within six months, confirmation of the failure to receive a response.

The Arizona member director position, one of the ~~FHLBanks’ obligation to promote diversity~~California member director positions, and ~~ensure inclusion.~~one of the independent director positions designated as a public interest director position, all with current terms ending December 31, 2018, will be filled through an election of the members located in Arizona (for the Arizona member director position), an election of members located in California (for the California member director position), and an election of all members of the Bank (for the public interest independent director position). The ~~final rule updates~~elections will be held in the ~~existing Finance Agency regulations aimed at promoting diversity~~fourth quarter of 2018. The Arizona and California member director positions and the ~~inclusion and use~~public interest independent director position will each have a four-year term that begins on January 1, 2019.

Table of minorities, women, and individuals with disabilities, and the businesses they own (MWDOB) in all FHLBank business and activities, including management, employment, and contracting. The final rule will:Contents

require the FHLBanks to develop standalone diversity and inclusion strategic plans or incorporate diversity and inclusion into their existing strategic planning processes and adopt strategies for promoting diversity and ensuring inclusion;

~~encourage the FHLBanks to expand contracting opportunities for minorities, women, and individuals with disabilities through subcontracting arrangements;~~

~~require the FHLBanks to develop policies that address reasonable accommodations for employees to observe their religious beliefs;~~

require the FHLBanks to provide information in their annual reports to the Finance Agency about their efforts to advance diversity and inclusion through financial transactions, identification of ways in which FHLBanks might be able to improve MWDOB business with the FHLBank by enhancing customer access by MWDOB businesses, including through its affordable housing and community investment programs and strategies for promoting the diversity of supervisors and managers; and

~~require the FHLBanks to classify and provide additional data in their annual reports about the number of and amounts paid under its contracts with MWDOB.~~

The Bank does not expect this final rule to materially affect its financial condition or results of operations, but anticipates that it may result in increased compliance costs and substantially increase the amount of tracking, monitoring, and reporting that would be required of the Bank.

Off-Balance Sheet Arrangements ~~Guarantees,~~ and Other Commitments

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 Bank determined that it was not necessary to recognize a liability for the fair value of the Bank's joint and~~

~~several liability for all consolidated obligations. The joint and several obligations are mandated by the FHLBank~~

~~Act or regulations governing the operations of the FHLBanks and are not the result of arms-length transactions~~

~~among the FHLBanks. The FHLBanks have no control over the amount of the guarantee or the determination of~~

~~how each FHLBank would perform under the joint and several obligations. Because the FHLBanks are subject to~~

~~the authority of the Finance Agency as it relates to decisions involving the allocation of the joint and several~~

~~liability for the FHLBanks' consolidated obligations, the FHLBanks' joint and several obligations are excluded from~~

~~the initial recognition and measurement provisions. Accordingly, the Bank has not recognized a liability for its joint~~

~~and several obligations related to other FHLBanks' participations in the consolidated obligations.~~ The par value of the outstanding consolidated obligations of the FHLBanks was ~~$1,028.7~~$1,059.9 billion at ~~September~~June 30, ~~2017~~2018, and ~~$989.3~~$1,034.3 billion at December 31, ~~2016~~2017. The par value of the Bank’s participation in consolidated obligations was ~~$102.2~~$98.7 billion at ~~September~~June 30, ~~2017,~~2018, and ~~$83.7~~$115.6 billion at December 31, ~~2016.~~2017. The Bank had committed to the issuance of ~~$1.1 billion~~$57 million and ~~$1.5 billion~~$729 million in consolidated obligations at ~~September~~June 30, ~~2017,~~2018, and December 31, ~~2016,~~2017, respectively.

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 Statement of Condition or may be recorded on the Bank’s Statement 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 ~~September~~June 30, ~~2017~~2018, the Bank had ~~$1 million~~ inno advance commitments and $~~15.5~~16.8 billion in standby letters of credit outstanding. At December 31, ~~2016~~2017, the Bank had $61 million in advance commitments and $~~15.2~~16.2 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 –4.0% 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 –6.0% 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 ~~September~~June 30, ~~2017.~~2018.

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 mortgage prepayment assumptions in the third-party model to other sources, including actual mortgage prepayment history.

~~109~~

The table below 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 ~~September~~June 30, ~~2017,~~2018, are comparable to the estimates as of December 31, ~~2016.~~2017, for rising rate scenarios and show less favorable sensitivity in declining rate scenarios. The change in sensitivity in the declining rate scenarios is related to faster projected mortgage prepayment speeds for fixed rate mortgage loans purchased under the MPF Program. LIBOR interest rates as of ~~September~~June 30, ~~2017,~~2018, were 3870 basis points higher for the 1-year term, 363 basis points higher for the 5-year term, and 553 basis points ~~lower~~higher for the 10-year term.

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 three-month LIBOR 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 ~~219%~~224% as of ~~September~~June 30, ~~2017.~~2018.

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’ JCE Agreement. Economic earnings exclude these amounts in order to more accurately reflect the amount of earnings that may be available to be paid as dividends to shareholders.

~~110~~

~~Table of Contents~~

The Bank limits the sensitivity of projected financial performance through a Board of Directors 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. With the indicated interest rate shifts, the adjusted return on capital for the projected 12-month horizon would be expected to decrease by 1485 basis points in the –200 basis points scenario, ~~well~~which is 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. ~~The Bank’s duration gap was one month at September 30, 2017, and one month at December 31, 2016.~~

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 offsetting 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, the Bank invests in non-MBS agency securities, generally with terms of less than three years. These investments may be variable rate or fixed rate, and the interest rate risk resulting from the fixed rate coupon is hedged with an interest rate swap or fixed rate debt.

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, 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 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

~~111~~

~~Table of Contents~~

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. The analyses are prepared under base case and alternate interest rate scenarios to assess the effect of options embedded in the advances, related financing, and hedges. These analyses are also 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).

108

Table of Contents

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 held-to-maturity (HTM) or available-for-sale (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 impact of mortgage prepayments and the existence of interest rate caps on certain adjustable rate MBS.

Historically, the Bank purchased a mix of intermediate-term fixed rate and adjustable rate MBS. The last purchase of a fixed rate MBS was in March 2014. Since March 2014, all MBS purchases were agency adjustable rate MBS. MPF loans that have been acquired are medium- or long-term fixed rate mortgage assets. This results in a mortgage portfolio that has a diversified set of interest rate risk attributes.

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 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 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

~~112~~

~~Table of Contents~~

fixed rate debt, callable fixed rate debt, or 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.

The following table presents results of the estimated market value of capital sensitivity analysis attributable to the mortgage-related business as of ~~September~~June 30, ~~2017,~~2018, and December 31, ~~2016.~~2017.

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.

~~113~~

~~Table of Contents~~

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 senior 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 senior 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 ~~September~~June 30, ~~2017,~~2018, 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.

Table of Contents

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.
