(Dollars in millions except per share amounts)

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, 2015. 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, 2014 (2014 Form 10‑K).

Use of Estimates. The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP) requires management to make a number of judgments, estimates, and assumptions that may affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities, and the reported amounts of income, expenses, gains, and losses during the reporting period. The most significant of these estimates include estimating 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.

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 June 30, 2015, 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.

Notes to Financial Statements (continued)

Gains on Litigation Settlements, Net. Litigation settlement gains, net of related legal expenses, are recorded in Other Income/(Loss) in “Gains on litigation settlements, net” in the Statements of Income. A litigation settlement gain is considered realized and recorded when the Bank receives cash or assets that are readily convertible to known amounts of cash or claims to cash. In addition, a litigation settlement gain is considered realizable and recorded when the Bank enters into a signed agreement that is not subject to appeal, where the counterparty has the ability to pay, and the amount to be received can be reasonably estimated. Prior to being realized or realizable, the Bank considers potential litigation settlement gains to be gain contingencies, and therefore they are not recorded in the Statements of Income. The related legal expenses are contingent-based fees and are only incurred and recorded upon a litigation settlement gain.

Descriptions of the Bank’s significant accounting policies are included in “Item 8. Financial Statements and Supplementary Data – Note 1 – Summary of Significant Accounting Policies” in the Bank’s 2014 Form 10-K. Other changes to these policies as of June 30, 2015, are discussed in Note 2 – Recently Issued and Adopted Accounting Guidance.

Note 2 — Recently Issued and Adopted Accounting Guidance

Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement. On April 15, 2015, the Financial Accounting Standards Board (FASB) issued amendments to clarify a customer’s accounting for fees paid in a cloud computing arrangement. The amendments provide guidance to customers on determining whether a cloud computing arrangement includes a software license that should be accounted for as internal-use software. If the arrangement does not contain a software license, it would be accounted for as a service contract. This guidance becomes effective for the Bank for the interim and annual periods beginning after December 15, 2015, and early adoption is permitted. The Bank can elect to adopt the amendments either (1) prospectively to all arrangements entered into or materially modified after the effective date or (2) retrospectively. The Bankis in the process of evaluating this guidance and its effect on the Bank’s financial condition, results of operations, and cash flows.

Simplifying the Presentation of Debt Issuance Costs. On April 7, 2015, the FASB issued guidance to simplify the presentation of debt issuance costs. This guidance requires that debt issuance costs related to a recognized debt liability be presented on the statement of condition as a direct deduction from the carrying amount of that debt liability, consistent with the presentation of debt discounts. The adoption of this guidance will result in a reclassification of debt issuance costs from other assets to consolidated obligations on the Bank’s Statements of Condition. This guidance becomes effective for the Bank for the interim and annual periods beginning after December 15, 2015, and early adoption is permitted for financial statements that have not been previously issued. The guidance is required to be applied on a retrospective basis to each individual period presented on the statement of condition. The Bank is in the process of evaluating this guidance and its effect on the Bank’s financial condition, results of operations, and cash flows.

Amendments to the Consolidation Guidance. On February 18, 2015, the FASB issued guidance intended to enhance consolidation guidance for legal entities such as limited partnerships, limited liability corporations, and securitization structures (collateralized debt obligations, collateralized loan obligations, and mortgage-backed security transactions). The new guidance primarily focuses on the following:

• Placing more emphasis on risk of loss when determining a controlling financial interest. A reporting organization may no longer have to consolidate a legal entity in certain circumstances based solely on its fee arrangement, when certain criteria are met.

• Reducing the frequency of the application of related-party guidance when determining a controlling financial interest in a VIE.

• Changing consolidation conclusions for public and private companies in several industries that typically make use of limited partnerships or VIEs.

Federal Home Loan Bank of San Francisco

Notes to Financial Statements (continued)

This guidance becomes effective for the Bank for interim and annual periods beginning after December 15, 2015, and early adoption is permitted, including adoption in an interim period. This guidance is not expected to affect the Bank’s financial condition, results of operations, and cash flows.

Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern.On August 27, 2014, the FASB issued guidance about management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosures. This guidance requires management to perform interim and annual assessments of an entity’s ability to continue as a going concern within one year after the date the financial statements are issued or within one year after the financial statements are available to be issued, when applicable. Substantial doubt exists if it is probable that the entity will be unable to meet its obligations for the assessed period. This guidance becomes effective for the Bank for the interim and annual periods ending after December 15, 2016, and early application is permitted. This guidance is not expected to affect the Bank’s financial condition, results of operations, and cash flows.

Classification of Certain Government-Guaranteed Mortgage Loans upon Foreclosure.On August 8, 2014, the FASB issued amended guidance relating to the classification and measurement of certain government-guaranteed mortgage loans upon foreclosure. The amendments in this guidance require that a mortgage loan be derecognized and that a separate other receivable be recognized upon foreclosure if certain conditions are met. This guidance became effective for the Bank for the interim and annual periods beginning on January 1, 2015, and was adopted prospectively. The adoption of this guidance did not affect the Bank’s financial condition, results of operations, or cash flows.

Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures.On June 12, 2014, the FASB issued amended guidance for repurchase-to-maturity transactions and repurchase agreements executed as repurchase financings. Specifically, this guidance requires entities to account for (1) repurchase-to-maturity transactions as secured borrowings rather than as sales with forward repurchase agreements; and (2) repurchase agreements executed contemporaneously with the initial transfer of the underlying financial asset with the same counterparty as separate transactions only. In addition, this guidance requires a transferor to disclose additional information about certain transactions, including those in which it retains substantially all of the exposure to the economic returns of the underlying transferred asset over the transaction’s term. This guidance became effective for the Bank for the interim and annual periods beginning on January 1, 2015. The changes in accounting for transactions outstanding on the effective date are required to be presented on a cumulative-effect basis. The adoption of this guidance did not affect the Bank’s financial condition, results of operations, 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 entities to use in accounting for 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, or lease contracts.

This guidance becomes effective for the interim and annual reporting periods beginning after December 15, 2016, and early application is not permitted. The guidance provides the entities with the option of using the following two methods upon adoption: a full retrospective method, applied retrospectively to each prior reporting period presented; or a transition method, with the cumulative effect of retrospectively applying this guidance recognized at the date of initial application. The Bank is in the process of evaluating this guidance and its effect on the Bank’s financial condition, results of operations, and cash flows, but it is not expected to be material.

Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure. On January 17, 2014, theFASB issued guidance clarifying when consumer mortgage loans collateralized by real estate should be reclassified to REO. Specifically, these collateralized mortgage loans should be reclassified to REO when

either the creditor obtains legal title to the residential real estate property upon completion of a foreclosure or the borrower conveys all interest in the residential real estate property to the creditor to satisfy the loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. The guidance became effective for interim and annual periods beginning on January 1, 2015, and was adopted prospectively. The adoption of this guidance did not affect the Bank’s financial condition, results of operations, or cash flows.

Regulatory Guidance

Framework for Adversely Classifying Loans, Other Real Estate Owned, and Other Assets and Listing Assets for Special Mention.On April 9, 2012, the Finance Agency issued Advisory Bulletin 2012-02, Framework for Adversely Classifying Loans, Other Real Estate Owned, and Other Assets and Listing Assets for Special Mention (AB 2012-02). The guidance establishes a standard and uniform methodology for classifying loans, other real estate owned, and certain other assets (excluding investment securities) and prescribes the timing of asset charge-offs based on these classifications. The guidance is generally consistent with the Uniform Retail Credit Classification and Account Management Policy issued by the federal banking regulators in June 2000. The Bank implemented the asset classification provisions as of January 1, 2014, and this adoption did not have any impact on the Bank’s financial condition, results of operations, or cash flows. The charge-off provisions were implemented on January 1, 2015, and resulted in a $1 charge-off to the Bank’s allowance for credit losses on the mortgage loan portfolio for the six months ended June 30, 2015. The adoption of these charge-off provisions did not have a material effect on the Bank’s financial condition, results of operations, or cash flows.

Note 3 — Trading Securities

The estimated fair value of trading securities as of June 30, 2015, and December 31, 2014, was as follows:

	June 30, 2015		December 31, 2014
Government-Sponsored Enterprises (GSEs) – Federal Farm Credit Bank (FFCB) bonds	$	2,913	$	3,513
MBS – Other U.S. obligations – Ginnie Mae	10		11
Total	$	2,923	$	3,524

The net unrealized gain/(loss) on trading securities was de minimis for the three and six months ended June 30, 2015 and 2014. These amounts represent the changes in the fair value of the securities during the reported periods.

Note 4 — Available-for-Sale Securities

Available-for-sale (AFS) securities by major security type as of June 30, 2015, and December 31, 2014, were as follows:

Expected maturities of PLRMBS will differ from contractual maturities because borrowers generally have the right to prepay the underlying obligations without prepayment fees.

At June 30, 2015, the amortized cost of the Bank’s PLRMBS classified as AFS included credit-related OTTI of $1,104. At December 31, 2014, the amortized cost of the Bank’s PLRMBS classified as AFS included credit-related OTTI of $1,173.

The following table summarizes the AFS securities with unrealized losses as of June 30, 2015, and December 31, 2014. 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 total gross unrealized 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 primarily related to 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, uncertainty about the future condition of the housing and mortgage markets and the economy, and market expectations of the credit performance of the loan collateral underlying these securities, which caused these assets to be valued at discounts to their acquisition 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 June 30, 2015, and December 31, 2014, 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.

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 meet neither 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 2.0% to an increase of 8.0% over the 12-month period beginning April 1, 2015. For the vast majority of markets, the projected short-term housing price changes range from an increase of 2.0% to an increase of 5.0%. 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 June 30, 2015 (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 in the second quarter of 2015, 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 (Prime; Alt-A, option ARM; and Alt-A, other) is based on the model used to run the estimated cash flows for the CUSIP, which may not necessarily be the same as the classification at the time of origination.

The following table presents the credit-related OTTI, which is recognized in earnings, for the three and six months ended June 30, 2015 and 2014.

	Three Months Ended June 30,						Six Months Ended June 30,

(1) For the three months ended June 30, 2015 and 2014, “securities for which OTTI was previously recognized” represents all securities that were also other-than-temporarily impaired prior to April 1, 2015 and 2014, respectively. For the six months ended June 30, 2015 and 2014, “securities for which OTTI

was previously recognized” represents all securities that were also other-than-temporarily impaired prior to January 1, 2015 and 2014, respectively

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 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, 2015. 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 six months ended June 30, 2014.

For the Bank’s PLRMBS that were not other-than-temporarily impaired as of June 30, 2015, the Bank has experienced net unrealized losses primarily because of illiquidity in the PLRMBS market, uncertainty about the future condition of the housing and mortgage markets and the economy, and market expectations of the credit performance of loan collateral underlying these securities, which caused these assets to be valued at discounts to their acquisition 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 June 30, 2015, 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 June 30, 2015, 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.

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 June 30, 2015, 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 0.16% to 8.57% at June 30, 2015, and 0.14% to 8.57% at December 31, 2014, 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 $4,782 at June 30, 2015, and $4,915 at December 31, 2014. Some advances may be repaid on pertinent call dates without prepayment fees (callable advances). The Bank had callable advances outstanding totaling $10,323 at June 30, 2015, and $328 at December 31, 2014.

The Bank’s advances at June 30, 2015, and December 31, 2014, included $140 and $140, respectively, of putable advances. 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.

The following table summarizes advances at June 30, 2015, and December 31, 2014, 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.

(1) Interest income amounts exclude the interest effect of interest rate exchange agreements with derivative counterparties; as a result, the total interest income amounts will not agree to the Statements of Income. The amount of interest income from advances can vary depending on the amount outstanding, terms to maturity, interest rates, and repricing characteristics.

(2) Nonmember institution.

The Bank held a security interest in collateral from each of the top five advances borrowers and their affiliates sufficient to support their respective advances outstanding, and the Bank does not expect to incur any credit losses on these advances.

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

Interest Rate Payment Terms. Interest rate payment terms for advances at June 30, 2015, and December 31, 2014, are detailed below:

	June 30, 2015		December 31, 2014
Par value of advances:
Fixed rate:

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 June 30, 2015, or December 31, 2014. 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, as follows:

	Three Months Ended						Six Months Ended

Note 8 — Mortgage Loans Held for Portfolio

Under the Mortgage Partnership Finance® (MPF®) Program, the Bank may purchase conventional conforming fixed rate mortgage loans and FHA/VA-insured mortgage loans from members for the Bank’s own portfolio under the Original MPF and MPF Government products. In addition, the Bank may facilitate the purchase of fixed rate mortgage loans from members for concurrent sale to Fannie Mae under the MPF Xtra® product. (“Mortgage Partnership Finance,” “MPF,” and “MPF Xtra” are registered trademarks of the FHLBank of Chicago.) As of June 30, 2015, the Bank had approved six members as participating financial institutions since renewing its participation in the MPF Program in the fourth quarter of 2013.

From May 2002 through October 2006, the Bank purchased conventional conforming fixed rate mortgage loans from its participating financial institutions under the Original MPF and MPF Plus products. Participating members originated or purchased the mortgage loans, credit-enhanced them and sold them to the Bank, and generally retained the servicing of the loans.

The following table presents information as of June 30, 2015, and December 31, 2014, on mortgage loans, all of which are secured by one- to four-unit residential properties and single-unit second homes.

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: 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 2014 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 June 30, 2015, and December 31, 2014, 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 six months ended June 30, 2015, or during 2014.

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 June 30, 2015, 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.

Nomember institutions were placed into receivershipduring the first six months of 2015 or from July 1 to July 31, 2015.

Mortgage Loans Held for Portfolio. The following table presents information on delinquent mortgage loans as of June 30, 2015, and December 31, 2014.

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 a credit risk exposure at the time of purchase equivalent to assets rated AA, taking into 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.

The Bank calculates its estimated allowance for credit losses on mortgage loans acquired under the Original MPF and MPF Plus products as described below. Effective January 1, 2015, the Bank implemented the accounting requirements of regulatory Advisory Bulletin 2012-02. As a result, for any mortgage loans that are more than 180 days past due and that have any outstanding balance in excess of the fair value of the property, less cost to sell, this excess is charged off as a loss by the end of the month in which the applicable time period elapses. Likewise, when a borrower is in bankruptcy, loans are written down to the fair value of the collateral, less cost to sell, in general within 60 days of receipt of the notification of filing from the bankruptcy court, unless it can be clearly demonstrated and documented that repayment is likely to occur. As a result of these charge-offs during the first six months of 2015, the corresponding Allowance for Credit Losses on MPF Loans, which had previously provided for most of these expected losses, was reduced accordingly.

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 an allowance for credit losses for Original MPF loans totaling a de minimis

26

Federal Home Loan Bank of San Francisco

Notes to Financial Statements (continued)

amount as of June 30, 2015, and December 31, 2014, and for MPF Plus loans totaling a de minimis amount as of June 30, 2015, and $1 as of December 31, 2014.

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 Original MPF loans totaling a de minimis amount as of June 30, 2015, and December 31, 2014, and for MPF Plus loans totaling a de minimis amount as of June 30, 2015, and December 31, 2014.

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 Bank’s TDRs of MPF loans primarily involve modifying the borrower’s monthly payment for a period of up to 36 months to reflect a housing expense ratio that is no more than 31% of the borrower’s qualifying monthly income. The outstanding principal balance is re-amortized to reflect a principal and interest payment for a term not to exceed 40 years from the original note date and a housing expense ratio not to exceed 31%. This would result in a balloon payment at the original maturity date of the loan because the maturity date and number of remaining monthly payments are not adjusted. If the 31% ratio is still not achieved through re-amortization, the interest rate is reduced in 0.125% increments below the original note rate, to a floor rate of 3.00%, resulting in reduced principal and interest payments, for the temporary payment modification period of up to 36 months, until the 31% housing expense ratio is met. The recorded investment of the Bank's nonperforming MPFloans classified as TDRs totaled $2.7 as of June 30, 2015, and $2.3 as of December 31, 2014.

Term Securities Purchased Under Agreements to Resell. Securities purchased under agreements to resell are considered collateralized financing arrangements and effectively represent short-term loans to counterparties that are considered by the Bank to be of investment quality, which are classified as assets in the Statements of Condition. Securities purchased under agreements to resell are held in safekeeping in the name of the Bank by third-party custodians approved by the Bank. In accordance with the terms of these loans, if the market value of the underlying securities decreases below the market value required as collateral, the counterparty must place an equivalent amount of additional securities as collateral or remit an equivalent amount of cash. If an agreement to resell is deemed to be impaired, the difference between the fair value of the collateral and the amortized cost of the agreement is charged to earnings. Based upon the collateral held as security, the Bank determined that no allowance for credit losses was needed for the term securities purchased under agreements to resell at June 30, 2015. The Bank did not have any term securities purchased under agreements to resell at December 31, 2014.

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 June 30, 2015, and December 31, 2014, were repaid or are expected to be repaid according to the contractual terms.

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 Statements and Supplementary Data – Note 20 – Commitments and Contingencies” in the Bank’s 2014 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 June 30, 2015, and December 31, 2014.

The Bank’s participation in consolidated obligation bonds outstanding includes callable bonds of $11,640 at June 30, 2015, and $14,158 at December 31, 2014. 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 $7,400 at June 30, 2015, and $9,573 at December 31, 2014. 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 June 30, 2015, and December 31, 2014, was as follows:

The Bank did not have any bonds 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 June 30, 2015, or December 31, 2014. The Bank has generally elected to account for bonds with embedded features under the fair value option, and these bonds are carried at fair value on the Statements of Condition.

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.

As of June 30, 2015, and December 31, 2014, the Bank was in compliance with these capital rules and requirements as shown in the following table.

Effective August 3, 2015, the Bank reduced its activity-based stock requirements within the ranges authorized by the Bank’s capital plan. The activity-based stock requirement for advances was reduced from 3.0% to 2.7%, and the activity-based stock requirement for mortgage loans purchased from the member and held by the Bank was reduced from 3.0% to 0.0%.

Mandatorily Redeemable Capital Stock. The Bank had mandatorily redeemable capital stock totaling $142 outstanding to 10 institutions at June 30, 2015, and $719 outstanding to 32 institutions at December 31, 2014. The change in mandatorily redeemable capital stock for the three and six months ended June 30, 2015 and 2014, was as follows:

	Three Months Ended						Six Months Ended
	June 30, 2015			June 30, 2014			June 30, 2015			June 30, 2014

Cash dividends on mandatorily redeemable capital stock were recorded as interest expense in the amount of $38 and $53 for the three and six months ended June 30, 2015, respectively, and in the amount of $34 and $73 for the three and six months ended June 30, 2014, respectively.

The Bank’s mandatorily redeemable capital stock is discussed more fully in “Item 8. Financial Statements and Supplementary Data – Note 15 – Capital” in the Bank’s 2014 Form 10-K.

The following table presents mandatorily redeemable capital stock amounts by contractual redemption period at June 30, 2015, and December 31, 2014.

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.

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 201% as of June 30, 2015.

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.

Retained Earnings – The Bank’s Excess Stock Repurchase, Retained Earnings, and Dividend Framework establishes amounts to be retained in restricted retained earnings, which are not made available in the current dividend period.

The following table summarizes the activity related to restricted retained earnings for the three and six months ended June 30, 2015 and 2014:

Notes to Financial Statements (continued)

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 June 30, 2015, the Bank’s excess capital stock totaled $365, or 0.42% of total assets.

In the second quarter of 2015, the Bank paid dividends on the capital stock outstanding during the first quarter of 2015 at an annualized rate of 22.65%, totaling $220, including $182 in dividends on capital stock and $38 in dividends on mandatorily redeemable capital stock. The dividends included a special dividend in the amount of $145, including $120 in dividends on capital stock and $25 in dividends on mandatorily redeemable capital stock. In the second quarter of 2014, the Bank paid dividends on the capital stock outstanding during the first quarter of 2014 at an annualized rate of 6.80%, totaling $93, including $59 in dividends on capital stock and $34 in dividends on mandatorily redeemable capital stock.

In the first six months of 2015, the Bank paid dividends at an annualized rate of 14.58%, totaling $294, of which $145 was related to the special dividend. The total dividends paid included $241 in dividends on capital stock and $53 in dividends on mandatorily redeemable capital stock. In the first six months of 2014, the Bank paid dividends at an annualized rate of 6.73%, totaling $190, including $117 in dividends on capital stock and $73 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 July 28, 2015, the Bank’s Board of Directors declared a cash dividend on the capital stock outstanding during the second quarter of 2015 at an annualized rate of 10.01%, totaling $78, including $72 in dividends on capital stock and $6 in dividends on mandatorily redeemable capital stock. The Bank recorded the dividend on July 28, 2015. The Bank expects to pay the dividend on or about August 13, 2015. Dividends on mandatorily redeemable capital stock will be recognized as interest expense in the third quarter of 2015.

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 some or all of a shareholder’s excess capital stock at the shareholder’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 $750 and $847 in excess capital stock in the first and second quarters of 2015, respectively, and $750 in excess capital stock in each of the first and second quarters of 2014.

During the second quarter of 2015 and 2014, the Bank redeemed $28 and $6, respectively, 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.

Notes to Financial Statements (continued)

On May 29, 2015, the Bank's Excess Stock Repurchase, Retained Earnings, and Dividend Framework (Framework) was revised to reinstate the Bank’s practice of repurchasing the surplus capital stock of all members and the excess capital stock of all nonmember shareholders on a regular quarterly schedule, at the Bank’s discretion and subject to certain statutory and regulatory requirements and to the Bank’s Risk Management Policy and capital plan limitations. Surplus capital stock is defined as any stock holdings in excess of 115% of a member’s minimum stock requirement, and excess capital stock is defined as any stock holdings in excess of a shareholder’s minimum stock requirement. In accordance with the revised Framework, each quarter, Bank management will evaluate and determine the amount of capital stock to be repurchased in that quarter, if any, giving consideration to certain capital metrics and capital management objectives and strategies, and subject to the requirements and limitations mentioned above. In addition, at the Bank’s discretion, some or all of the excess stock held by a shareholder may be repurchased upon request of the shareholder, subject to the requirements and limitations mentioned above. At least 15 calendar days before any repurchase, the Bank will notify shareholders of its intention to repurchase capital stock and of the scheduled repurchase date. On the scheduled repurchase date, the Bank will calculate the amount of stock to be repurchased to ensure that each member and nonmember shareholder will continue to meet its minimum stock requirement after the repurchase.

On July 29, 2015, the Bank announced that it plans to repurchase the surplus capital stock of all members and the excess capital stock of all nonmember shareholders on August 14, 2015.

Excess capital stock totaled $365 as of June 30, 2015, and $1,118 as of December 31, 2014.

For more information on excess capital stock, see “Item 8. Financial Statements and Supplementary Data – Note 15 – Capital” in the Bank’s 2014 Form 10-K.

major 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 2014 Form 10-K.

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 and the issuance of consolidated obligation bonds to create variable rate structures. The interest rate exchange agreements are generally executed at 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 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 derivative 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 that may be executed with members (with the Bank serving as an intermediary) or 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, (ii) an economic hedge of a specific asset or liability, or (iii) an intermediary transaction for members.

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 indexed to LIBOR.

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 all relationships between derivative hedging instruments and hedged items, its risk management objectives and strategies for undertaking various hedge transactions, and its method of assessing effectiveness. This process includes linking all derivatives that are designated as fair value or cash flow hedges to: (i) assets and liabilities on the balance sheet, (ii) firm commitments, or (iii) forecasted transactions. The Bank also formally assesses (both at the hedge’s inception and on an ongoing basis) whether the derivatives that are used in hedging transactions have been effective in offsetting changes in the fair value or cash flows of hedged items attributable to the hedged risk and whether those derivatives may be expected to remain effective 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 or cash flows 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.

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 derivatives receives 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.

Notes to Financial Statements (continued)

The notional principal of the interest rate exchange agreements associated with offsetting derivatives with other counterparties was $160 at June 30, 2015. The Bank had no interest rate exchange agreements associated with derivatives with members or offsetting derivatives with other counterparties at December 31, 2014.

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 array 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 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 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.

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 mortgages with lower-yielding assets and the Bank’s higher funding costs are not reduced accordingly.

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

39

Federal Home Loan Bank of San Francisco

Notes to Financial Statements (continued)

available through the issuance of an adjustable rate bond alone. These transactions generally receive fair value hedge accounting treatment.

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 generally do not meet the requirements for fair value hedge accounting treatment.

The Bank did not have any consolidated obligations denominated in currencies other than U.S. dollars outstanding during the six months ended June 30, 2015, or the year ended December 31, 2014.

Credit Risk – The Bank is subject to credit risk as a result of the risk of potential nonperformance by counterparties to the derivative 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 and credit guidelines and Finance Agency regulations. The Bank also requires collateral agreements with collateral delivery thresholds on all uncleared derivatives. In addition, collateral related to derivative transactions with member institutions includes collateral pledged to the Bank, as evidenced by the Advances and Security Agreement, which may be held by the member institution for the benefit of the Bank.

For cleared derivatives, the clearinghouse is the Bank’s counterparty. The requirement that the Bank post initial and variation margin through the 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 and variation margin is posted daily for changes in the value of cleared derivatives through a clearing agent. 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 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 Bank’s agreements for uncleared derivative transactions contain provisions that link the Bank’s credit rating from Moody’s and Standard & Poor’s to various rights and obligations. Certain of these derivative agreements provide that, if the Bank’s long-term debt rating falls below A3/A- (and in one agreement, below A2/A), 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. In addition, under some of its agreements for uncleared derivative transactions, the amount of collateral that the Bank is required to deliver to a counterparty depends on the Bank’s credit rating. The aggregate fair value of all uncleared derivative instruments with credit-risk-related contingent features that were in a net derivative liability position (before cash collateral and

related accrued interest) at June 30, 2015, was $42, for which the Bank had posted collateral with a fair value of $36 in the ordinary course of business. If the Bank’s credit rating at June 30, 2015, had been lowered from its current rating to the next lower rating, that would have triggered additional collateral to be delivered, and the Bank would have been required to deliver up to a total of $2 of additional collateral (at fair value) to its derivative counterparties at June 30, 2015.

The following table summarizes the fair value of derivative instruments including the effect of netting adjustments and cash collateral as of June 30, 2015, and December 31, 2014.

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 June 30, 2015, and December 31, 2014. 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. 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 June 30, 2015, and December 31, 2014.

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: (1) quoted prices for similar assets or liabilities in active markets; (2) quoted prices for identical or similar assets or liabilities in markets that are not active; (3) inputs other than quoted prices that are observable for

the asset or liability (e.g., interest rates and yield curves that are observable at commonly quoted intervals, and implied volatilities); and (4) inputs that are derived principally from or corroborated by observable market data by correlation or other means.

• Level 3 – Unobservable inputs for the asset or liability.

A financial instrument’s categorization within the valuation hierarchy is based on the lowest level of input that is significant to the fair value measurement.

The following assets and liabilities, including those for which the Bank has elected the fair value option, are carried at fair value on the Statements of Condition as of June 30, 2015:

• 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 and Due from Banks–The estimated fair value equals the carrying value.

Federal Funds Sold and Securities Purchased Under Agreements to Resell – The estimated fair value 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 calculations are the replacement rates for comparable instruments with similar terms.

Investment Securities – Certificates of Deposit –The estimated fair values of these investments are determined by calculating the present value of expected cash flows and reducing the amount for accrued interest receivable, using market-observable inputs as of the last business day of the period or using industry standard analytical models and certain actual and estimated market information. The discount rates used in these calculations are the replacement rates for comparable instruments with similar terms.

Investment Securities – MBS – To value its MBS, the Bank obtains prices from four 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.

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

Notes to Financial Statements (continued)

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 four vendor prices are received, the average of the middle two prices is the median price; 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 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 June 30, 2015, four vendor prices were received for most of the Bank’s MBS, and the fair value estimates for most of those securities were determined by averaging the four 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 or significant yield variances, 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.

As an additional step, the Bank reviewed the fair value estimates of its PLRMBS as of June 30, 2015, for reasonableness using a market-implied yield test. The Bank calculated a market-implied yield for each of its PLRMBS using the estimated fair value derived from the process described above and the security’s projected cash flows from the Bank’s OTTI process and compared the market-implied yield to the yields for comparable securities according to dealers and other third-party sources to the extent comparable market yield data was available. This analysis did not indicate that any adjustments to the fair value estimates were necessary.

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 –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 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 from derivative dealers for complex advances. 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

47

Notes to Financial Statements (continued)

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 for creditworthiness primarily because advances were fully collateralized.

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 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; 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; and prepayment assumptions.

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 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 security 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 credit rating, as determined by rating agency long-term credit ratings of the counterparty’s debt securities or deposits, 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 strict 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.

Consolidated Obligations –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 inputs for measuring the fair value of consolidated obligation bonds are market-based CO Curve inputs obtained from the Office of Finance. The Office of Finance constructs the CO Curve using the Treasury yield curve as a base curve, which may be adjusted by indicative 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 trades or secondary market activity. For consolidated obligation bonds with embedded options, the Bank also obtains market-observable quotes and inputs from derivative dealers. 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).

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 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 Measurements. The tables below present the fair value of assets and liabilities, which are recorded on a recurring or nonrecurring basis at June 30, 2015, and December 31, 2014, by level within the fair value hierarchy.

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 2014 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 table summarizes the activity related to financial assets and liabilities for which the Bank elected the fair value option during the three and six months ended June 30, 2015 and 2014:

	Three Months Ended
	June 30, 2015						June 30, 2014

Balance, end of the period	$	4,978		$	6,203		$	6,341		$	7,080

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 in fair value does not include changes in instrument-specific credit risk. For advances and consolidated obligations recorded under the fair value option, the Bank determined that no adjustments to the fair values of these instruments for instrument-specific credit risk were necessary for the three and six months ended June 30, 2015 and 2014.

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 June 30, 2015, and December 31, 2014:

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 June 30, 2015, 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 $852,783 at June 30, 2015, and $847,175 at December 31, 2014. The par value of the Bank’s participation in consolidated obligations was $79,210 at June 30, 2015, and $68,538 at December 31, 2014. For more information on the joint and several liability regulation, see “Item 8. Financial Statements and Supplementary Data – Note 20 – Commitments and Contingencies” in the Bank’s 2014 Form 10-K.

Off-balance sheet commitments as of June 30, 2015, and December 31, 2014, were as follows:

	June 30, 2015						December 31, 2014
	Expire Within One Year		Expire After One Year		Total		Expire Within One Year		Expire After One Year		Total

Commitments to issue consolidated obligation bonds, par(2)	595		—		595		—		—		—
Commitments to purchase mortgage loans	7		—		7		—		—		—

(1) AtJune 30, 2015, and December 31, 2014, $100 of the commitments to fund additional advances were hedged with associated interest rate swaps.

(2) AtJune 30, 2015, all of the unsettled consolidated obligation bonds were hedged with associated interest rate swaps.

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 44 days to 15 years, including a final expiration in 2030. The Bank monitors the creditworthiness of members that have standby letters of credit. In addition, standby letters of credit are fully collateralized. As a result, the Bank determined that it was not necessary to record any allowance for losses on these commitments at June 30, 2015, and December 31, 2014.

The value of the Bank’s obligations related to standby letters of credit is recorded in other liabilities and amounted to $16 at June 30, 2015, and $12 at December 31, 2014. 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

53

Federal Home Loan Bank of San Francisco

Notes to Financial Statements (continued)

deemed it unnecessary to record any additional liability on the letters of credit outstanding as of June 30, 2015, and December 31, 2014.

Commitments to fund advances totaled $177 at June 30, 2015, and $126 at December 31, 2014. 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 June 30, 2015, and December 31, 2014.

The Bank may enter into commitments that unconditionally obligate it to purchase mortgage loans from its members. Commitments are generally for periods not exceeding 30 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 with its members. The Bank enters into master agreements with netting provisions and into bilateral security 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. As of June 30, 2015, the Bank had pledged total cash collateral of $727 to counterparties and the clearing house that had market risk exposure to the Bank related to derivatives. As of December 31, 2014, the Bank had pledged total collateral of $502, including securities with a de minimis carrying value, all of which may be sold or repledged, and cash collateral of $502 to counterparties and the clearing house that had market risk exposure to the Bank related to derivatives.

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.

This Management’s Discussion and Analysis of Financial Condition and Results of Operations should be read in conjunction with the Bank’s interim financial statements and notes and the Bank’s 2014 Form 10-K.

Quarterly Overview

Net income for the second quarter of 2015 was $61 million, compared with net income of $39 million for the second quarter of 2014. The $22 million increase in net income for the second quarter of 2015 relative to the prior-year period reflected net fair value gains associated with derivatives, hedged items, and financial instruments carried at fair value, partially offset by lower net interest income.

Net interest income for the second quarter of 2015 was $108 million, down from $138 million for the second quarter of 2014. The decrease was primarily due to lower average balances of interest-earning assets, higher dividends paid on mandatory redeemable capital stock (which are classified as interest expense), and a decrease in earnings on invested capital because of lower average capital balances.

Other income/(loss) for the second quarter of 2015, was a loss of $2 million, compared with a loss of $54 million for the second quarter of 2014. The change reflected net fair value gains associated with derivatives, hedged items, and financial instruments carried at fair value of $5 million (compared with net fair value losses of $35 million for the second quarter of 2014), which were due to the effects of changes in market interest rates, interest rate spreads, interest rate volatility, and other market factors during the period. The change also reflected expense on derivative instruments used in economic hedges of $4 million (compared with expense of $19 million for the second quarter of 2014). Income/expense on derivative instruments used in economic hedges is generally offset by interest expense/income on the economically hedged assets and liabilities.

During the first six months of 2015, total assets increased $10.2 billion, to $86.0 billion at June 30, 2015, from $75.8 billion at December 31, 2014. Advances increased $11.2 billion, or 29%, to $50.2 billion at June 30, 2015, from $39.0 billion at December 31, 2014.

In addition, investments increased $1.5 billion, or 5%, to $33.5 billion at June 30, 2015, from $32.0 billion at December 31, 2014, primarily reflecting an increase in securities purchased under agreement to resell. These increases were partially offset by a $2.7 billion decrease in cash and due from banks, from $3.9 billion at December 31, 2014, to $1.2 billion at June 30, 2015.

Accumulated other comprehensive income/(loss) increased by $12 million during the first six months of 2015, to income of $68 million at June 30, 2015, from income of $56 millionatDecember 31, 2014, primarily as a result of improvement in the fair value of PLRMBS classified as available-for-sale (AFS).

Additional information about investments and other-than-temporary impairment (OTTI) losses associated with the Bank’s PLRMBS is provided in “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Risk Management – Investments” and in “Item 1. Financial Statements – Note 6 – Other-Than-Temporary Impairment Analysis.” Additional information about the Bank’s PLRMBS is also provided in “Part II. Item 1. Legal Proceedings.”

On June 23, 2015, the Bank paid a special dividend of $145 million on the capital stock outstanding during the first quarter of 2015, including $25 million in dividends on mandatorily redeemable capital stock that was reflected as interest expense in the second quarter of 2015. Combined with the dividend of $75 million paid on May 14, 2015, the annualized rate for dividends paid during the second quarter of 2015 was 22.65%.

On July 28, 2015, the Bank’s Board of Directors declared a cash dividend on the capital stock outstanding during the second quarter of 2015 at an annualized rate of 10.01%. The dividend will total $78 million, including $6 million in dividends on mandatorily redeemable capital stock that will be reflected as interest expense in the third quarter of 2015. The Bank recorded the dividend on July 28, 2015, and expects to pay the dividend on or about August 13, 2015.

57

As of June 30, 2015, the Bank was in compliance with all of its regulatory capital requirements. The Bank’s total regulatory capital ratio was 6.5%, exceeding the 4.0% requirement. The Bank had $5.5 billion in permanent capital, exceeding its risk-based capital requirement of $2.9 billion. Total retained earnings as of June 30, 2015, were $2.7 billion.

Effective August 3, 2015, the Bank reduced its activity-based stock requirements within the ranges authorized by the Bank’s capital plan. The activity-based stock requirement for advances was reduced from 3.0% to 2.7%, and the activity-based stock requirement for mortgage loans purchased from the member and held by the Bank was reduced from 3.0% to 0.0%.

The Bank plans to repurchase the surplus capital stock of all members and the excess capital stock of all nonmember shareholders on August 14, 2015. Surplus capital stock is defined as any stock holdings in excess of 115% of a member’s minimum capital stock requirement.

The Bank will continue to monitor 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 in future quarters.

(1) Investments consist of securities purchased under agreements to resell, Federal funds sold, trading securities, available-for-sale securities and held-to-maturity securities.

(2) 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 June 30, 2015, 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:

59

	Par Value (In millions)
June 30, 2015	$	852,783
March 31, 2015	812,197

September 30, 2014	816,950
June 30, 2014	799,979

(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

The primary source of the Bank’s earnings is net interest income, which is the interest earned on advances, mortgage loans, and investments, 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 six months ended June 30, 2015 and 2014, 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.

(4) Includes forward settling transactions and valuation adjustments for certain cash items.

(5) Includes non-credit-related OTTI losses on AFS and HTM securities.

(6) Net interest spread is the difference between the average rate earned on interest-earning assets and the average rate paid on interest-bearing liabilities.

(7) Net interest margin is net interest income (annualized) divided by average interest-earning assets.

Net interest income in the second quarter of 2015 was $108 million, a 22%decrease from $138 million in the second quarter of 2014. The following table details the changes in interest income and interest expense for the second quarter of 2015 compared to the second quarter of 2014. Changes in both volume and interest rates influence changes in net interest income, net interest spread, and net interest margin.

Net interest income included $8 million of advance prepayment fees in the second quarter of 2015 compared to $4 million in the second quarter of 2014.

The net interest margin was 53 basis points for second quarter of 2015, 11 basis points lower than the net interest margin for second quarter of 2014, which was 64 basis points. The net interest spread was 48 basis points for second quarter of 2015, 12 basis points lower than the net interest spread for second quarter of 2014, which was 60 basis points. These decreases were primarily due to dividends on mandatorily redeemable capital stock, which are classified as interest expense. Although the average balance of mandatorily redeemable capital stock was

62

significantly lower in the second quarter of 2015 than in the year-earlier period, interest expense related to dividends on mandatorily redeemable capital stock increased $4 million in the second quarter of 2015 relative to the year-earlier period because the Bank paid a special dividend of $145 million in the second quarter of 2015 that included a payment of $25 million on mandatorily redeemable capital stock. This increase in interest expense was partially offset by improved spreads on interest-earning assets, including the accretion of yield adjustments on certain other-than-temporarily impaired PLRMBS resulting from improvement in expected cash flows.

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.

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 unrealized net fair value gains/(losses) on advances and consolidated obligation bonds were primarily driven by the effects of changes in market interest rates, interest rate spreads, interest rate volatility, and other market factors relative to the actual terms on the advances and consolidated obligation bonds during the period.

Additional information about advances and consolidated obligation bonds held under the fair value option is provided in “Item 1. Financial Statements – Note 16 – Fair Value.”

During the second quarter of 2015, net gains on derivatives and hedging activities totaled $27 million compared to net losses of $24 million in the second quarter of 2014. These amounts included expense of $4 million and expense of $19 million resulting from net settlements on derivative instruments used in economic hedges in the second quarter of 2015 and 2014, 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.

The ongoing impact of these valuation adjustments on the Bank cannot be predicted and the effects of these valuation adjustments may lead to significant volatility in future earnings, including earnings available for dividends.

Net interest income included $8 million of advance prepayment fees in the first six months of 2015 compared to $4 million in the first six months of 2014.

The net interest margin was 61 basis points for the first six months of 2015, 3 basis points lower than the net interest margin for the first six months of 2014, which was 64 basis points. The net interest spread was 56 basis points for the first six months of 2015, 4 basis points lower than the net interest spread for the first six months of 2014, which was 60 basis points. These decreases were primarily due to dividends on mandatorily redeemable capital stock, which are classified as interest expense. Although the average balance of mandatorily redeemable

67

capital stock was significantly lower in the first six months of 2015 than in the year-earlier period, the amount of dividends paid on mandatorily redeemable capital stock declined only slightly because the Bank paid a special dividend in the second quarter of 2015 that included a payment of $25 million on mandatorily redeemable capital stock. This increase in dividends on mandatorily redeemable capital stock was partially offset by improved spreads on interest-earning assets, including the accretion of yield adjustments on certain other-than-temporarily impaired PLRMBS resulting from improvement in expected cash flows.

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.

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.

During the first six months of 2015, net gains on derivatives and hedging activities totaled $6 million compared to net losses of $34 million in the first six months of 2014. These amounts included expense of $13 million and

69

expense of $41 million resulting from net settlements on derivative instruments used in economic hedges in the first six months of 2015 and 2014, 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.

Gains on litigation settlements, net – During the first six months of 2015,gains relating to settlements with certain defendants in connection with the Bank’s PLRMBS litigation totaled $459 million (after netting certain legal fees and expenses).

Return on Average Equity

Return on average equity (ROE) was 4.27% (annualized) for the second quarter of 2015, compared to 2.80% (annualized) for the second quarter of 2014. This increase reflected the increase in net income in the second quarter of 2015 which rose 56%, from $39 million in the second quarter of 2014 to $61 million in the second quarter of 2015.

ROE was 18.39% (annualized) for the first six months of 2015, compared to 2.96% (annualized) for the first six months of 2014. The increase reflected the increase in net incomein the firstsixmonths of 2015 resulting from a $459 million gain (after netting certain legal fees and expenses) relating to settlements with certain defendants in connection with Bank’s PLRMBS litigation in the first quarter of 2015.

Dividends and Retained Earnings

Under regulations governing the operations of the FHLBanks, dividends may be paid only out of current net earnings or previously retained earnings. As required by the regulations, the Bank’s Excess Stock Repurchase, Retained Earnings, and Dividend Framework is reviewed at least annually by the Bank’s Board of Directors. The Board of Directors may amend the Excess Stock Repurchase, Retained Earnings, and Dividend Framework from time to time. In accordance with the Bank’s Excess Stock Repurchase, Retained Earnings, and Dividend Framework, the Bank retains certain amounts in restricted retained earnings, which are not made available for dividends in the current dividend period. The Bank may be restricted from paying dividends if it 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.

70

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 June 30, 2015, advances maturing within five years totaled $46.3 billion, significantly in excess of the $488 million of member deposits on that date. At December 31, 2014, advances maturing within five years totaled $37.0 billion, also significantly in excess of the $160 million of member deposits on that date. In addition, as of June 30, 2015, and December 31, 2014, the Bank’s estimated total sources of funds obtainable from liquidity investments, repurchase agreement borrowings collateralized by the Bank’s marketable securities, and advance repayments would have allowed the Bank to meet its liquidity needs for more than 90 days without access to the consolidated obligations markets, subject to certain conditions. For more information, see “Item 7. Management’s Discussion and Analysis of Results of Operations and Financial Condition – Risk Management – Liquidity Risk” in the Bank’s 2014 Form 10-K.

The Bank’s Risk Management Policy limits the payment of dividends 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 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 London Interbank Offered Rate (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 201% as of June 30, 2015. For more information, see “Item 7. Management’s Discussion and Analysis of Results of Operations and Financial Condition – Risk Management – Market Risk” in the Bank’s 2014 Form 10-K.

Retained Earnings Related to Valuation Adjustments – In accordance with the Bank’s Excess Stock Repurchase, Retained Earnings, and Dividend Framework, the Bank retains in restricted retained earnings any cumulative net gains in earnings (net of applicable assessments) resulting from valuation adjustments.

In general, the Bank’s derivatives and hedged instruments, as well as certain assets and liabilities that are carried at fair value, are held to the maturity, call, or put date. For these financial instruments, net valuation gains or losses are primarily a matter of timing and 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 exercised call or put dates. However, the Bank may have instances in which hedging relationships are terminated prior to maturity or prior to the call or put dates. Terminating the hedging relationship may result in a realized gain or loss. In addition, the Bank may have instances in which it may sell trading securities prior to maturity, which may also result in a realized gain or loss.

The purpose of retaining cumulative net gains in earnings resulting from valuation adjustments as restricted retained earnings is to provide sufficient retained earnings to offset future net losses that result from the reversal of cumulative net gains, so that potential dividend payouts in future periods are not necessarily affected by the reversals of these gains. Although restricting retained earnings in this way may preserve the Bank’s ability to pay dividends, the reversal of cumulative net gains in any given period may result in a net loss if the reversal exceeds net earnings before the impact of valuation adjustments for that period.

Retained earnings related to valuation adjustments totaled $33 million and $35 million at June 30, 2015, and December 31, 2014, respectively.

Other Retained Earnings – Targeted Buildup – In addition to any cumulative net gains resulting from valuation adjustments, the Bank holds an additional amount in restricted retained earnings intended to protect paid-in capital from the effects of an extremely adverse credit event, an extremely adverse operations risk event, a cumulative net loss related to the Bank’s derivatives and associated hedged items and financial instruments carried at fair value, an extremely adverse change in the market value of the Bank’s capital, a significant amount of additional credit-related OTTI on PLRMBS, or some combination of these effects, especially in periods of extremely low net income resulting from an adverse interest rate environment, and to maintain capital compliance.

71

The Board of Directors previously set the amount for the targeted buildup of restricted retained earnings at $1.8 billion. As of March 31, 2012, restricted retained earnings reached the $1.8 billion targeted amount, and the Bank has maintained this targeted amount through June 30, 2015. The Bank’s retained earnings target may be changed at any time. The Board of Directors periodically reviews the retained earnings methodology and analysis to determine whether any adjustments are appropriate. As of July 31, 2015, the Board of Directors set the amount for the targeted buildup of restricted retained earnings at $1.65 billion.

Joint Capital Enhancement Agreement – In 2011, the FHLBanks entered into a Joint Capital Enhancement Agreement, as amended (JCE Agreement), intended to enhance the capital position of each FHLBank by allocating a portion of each FHLBank’s earnings to a separate retained earnings account at that FHLBank. In accordance with the JCE Agreement, each FHLBank is required to allocate 20% of its net income each quarter to a separate restricted retained earnings account until the balance of the account equals at least 1% of that FHLBank’s average balance of outstanding consolidated obligations for the previous quarter. Under the JCE Agreement, these restricted retained earnings will not be available to pay dividends.

Retained earnings related to the JCE Agreement totaled $337 million and $230 million at June 30, 2015, and December 31, 2014, respectively.

For more information on these three categories of restricted retained earnings and the Bank’s Excess Stock Repurchase, Retained Earnings, and Dividend Framework, see “Item 1. Financial Statements – Note 13 – Capital” and “Item 8. Financial Statements and Supplementary Data – Note 15 – Capital” in the Bank’s 2014 Form 10-K.

Dividend Payments – Federal Housing Finance Agency (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 June 30, 2015, the Bank’s excess capital stock totaled $365 million, or 0.42% of total assets.

In the second quarter of 2015, the Bank paid dividends on the capital stock outstanding during the first quarter of 2015 at an annualized rate of 22.65%, totaling $220 million, including $182 million in dividends on capital stock and $38 million in dividends on mandatorily redeemable capital stock. The dividends included a special dividend in the amount of $145 million, including $120 million in dividends on capital stock and $25 million in dividends on mandatorily redeemable capital stock. In the second quarter of 2014, the Bank paid dividends on the capital stock outstanding during the first quarter of 2014 at an annualized rate of 6.80%, totaling $93 million, including $59 million in dividends on capital stock and $34 million in dividends on mandatorily redeemable capital stock.

In the first six months of 2015, the Bank paid dividends at an annualized rate of 14.58%, totaling $294 million, of which $145 million was related to the special dividend. The total dividends paid included $241 million in dividends on capital stock and $53 million in dividends on mandatorily redeemable capital stock. In the first six months of 2014, the Bank paid dividends at an annualized rate of 6.73%, totaling $190 million, including $117 million in dividends on capital stock and $73 million in dividends on mandatorily redeemable capital stock.

For the periods referenced above, the Bank paid these dividends in cash. Dividends on capital stock are recognized as dividends on the Statements of Capital Accounts, and dividends on mandatorily redeemable capital stock are recognized as interest expense on the Statements of Income.

On July 28, 2015, the Bank’s Board of Directors declared a cash dividend on the capital stock outstanding during the second quarter of 2015 at an annualized rate of 10.01% totaling $78 million, including $72 million in dividends on capital stock and $6 million in dividends on mandatorily redeemable capital stock. The Bank recorded the dividend on July 28, 2015. The Bank expects to pay the dividend on or about August 13, 2015. Dividends on mandatorily redeemable capital stock will be recognized as interest expense in the third quarter of 2015.

The Bank will continue to monitor 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 in future quarters.

For more information on the Bank’s Excess Stock Repurchase, Retained Earnings, and Dividend Framework, see “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations Results of Operations – Comparison of 2014 to 2013 – Dividends and Retained Earnings” in the Bank’s 2014 Form 10-K.

Financial Condition

Total assets were $86.0 billion at June 30, 2015, compared to $75.8 billion at December 31, 2014. Advances increased by $11.2 billion, or 29%, to $50.2 billion at June 30, 2015, from $39.0 billion at December 31, 2014. MBS decreased by $1.8 billion, or 9%, to $17.8 billion at June 30, 2015, from $19.6 billion at December 31, 2014. Average total assets were $83.0 billion for the second quarter of 2015, a 6%decrease compared to $87.9 billion for the second quarter of 2014. Average total assets were $79.8 billion for the first six months of 2015, an 8%decrease compared to $86.9 billion for the first six months of 2014. Average advances were $50.9 billion for the second quarter of 2015, an 8%increase from $47.0 billion for the second quarter of 2014. Average advances were $46.8 billion for the first six months of 2015, a 2%increase from $46.0 billion for the first six months of 2014. Average MBS were $18.1 billion for the second quarter of 2015, a 16%decrease from $21.5 billion for the second quarter of 2014. Average MBS were $18.6 billion for the first six months of 2015, a 15%decrease from $21.8 billion for the first six months of 2014.

Advances outstanding at June 30, 2015, included unrealized gains of $127 million, of which $69 million represented unrealized gains on advances hedged in accordance with the accounting for derivative instruments and hedging activities and $58 million represented unrealized gains on economically hedged advances that are carried at fair value in accordance with the fair value option. Advances outstanding at December 31, 2014, included unrealized gains of $156 million, of which $67 million represented unrealized gains on advances hedged in accordance with the accounting for derivative instruments and hedging activities and $89 million represented unrealized gains on economically hedged advances that are carried at fair value in accordance with the fair value option. The overall decrease in the unrealized gains on the hedged advances and advances carried at fair value from December 31, 2014, to June 30, 2015, 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.

Total liabilities were $80.5 billion at June 30, 2015, an increase of $10.4 billion from $70.1 billion at December 31, 2014, reflecting an increase in consolidated obligations outstanding from $68.9 billion at December 31, 2014, to $79.5 billion at June 30, 2015, partially offset by a decrease in mandatory redeemable capital stock from $0.7 billion at December 31, 2014, to $0.1 billion at June 30, 2015. The decrease in mandatorily redeemable capital stock was primarily attributable to the Bank’s repurchase of excess capital stock during the first six months of 2015. Average total liabilities were $77.3 billion for the second quarter of 2015, a 6%decrease compared to $82.2 billion for the second quarter of 2014. Average total liabilities were $73.9 billion for the first six months of 2015, a 9%decrease compared to $81.2 billion for the first six months of 2014. Average consolidated obligations were $75.4 billion for the second quarter of 2015 and $79.4 billion for the second quarter of 2014. Average consolidated obligations were $71.9 billion for the first six months of 2015 and $78.2 billion for the first six months of 2014. Average mandatorily redeemable capital stock was $0.3 billion for the second quarter of 2015, a 79%decrease compared to $1.4 billion for the second quarter of 2014. Average mandatorily redeemable capital stock was $0.5 billion for the first six months of 2015 and $1.71 billion for the first six months of 2014.

Consolidated obligations outstanding at June 30, 2015, included unrealized losses of $252 million on consolidated obligation bonds hedged in accordance with the accounting for derivative instruments and hedging activities and unrealized gains of $17 million on economically hedged consolidated obligation bonds that are carried at fair value

73

in accordance with the fair value option. Consolidated obligations outstanding at December 31, 2014, included unrealized losses of $308 million on consolidated obligation bonds hedged in accordance with the accounting for derivative instruments and hedging activities and unrealized gains of $31 million on economically hedged consolidated obligation bonds that are carried at fair value in accordance with the fair value option. The decrease in the unrealized losses on the hedged consolidated obligation bonds and the decrease in the unrealized gains on the consolidated obligation bonds carried at fair value from December 31, 2014, to June 30, 2015, 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 June 30, 2015, 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 $852.8 billion at June 30, 2015, and $847.2 billion at December 31, 2014.

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 June 30, 2015, 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.

The Bank’s financial condition is further discussed under “Segment Information.”

Segment Information

The Bank uses an analysis of financial performance based on the balances 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 to determine the allocation of resources to these two major 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 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$12.0 billion, or 22%, to $67.4 billion (78% of total assets) at June 30, 2015, from $55.4 billion (73% of total assets) at December 31, 2014.

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.

74

Adjusted net interest income for this segment was $47 million in the second quarter of 2015, an increase of $3 million, or 7%, compared with $44 million in the second quarter of 2014. In the first six months of 2015, adjusted net interest income for this segment was $82 million, a decrease of $1 million, or 1%, compared to $83 million in the first six months of 2014. The increase in adjusted net interest income for the second quarter of 2015 was primarily due to higher earnings on advances and prepayment fees, partially offset by a decline in earnings on invested capital because of lower average capital balances.

Adjusted net interest income for this segment represented 34% and 30% of total adjusted net interest income for the second quarter of 2015 and 2014, and 31% and 28% of total adjusted net interest income for the first six months of 2015 and 2014, respectively.

Members and nonmember borrowers prepaid $638 million of advances in the second quarter of 2015 compared to

$555 million in the second quarter of 2014. Interest income was increased by net prepayment fees of $8 million in

the second quarter of 2015 and $4 million in the second quarter of 2014. Members and nonmember borrowers

prepaid $1.2 billion of advances in the first six months of 2015 compared to $705 million in the first six months of 2014. Interest income was increased by net prepayment fees of $8 million in the first six months of 2015 and $4

million in the first six months of 2014.

Advances – The par value of advances outstanding increased by $11.3 billion, or 29%, to $50.1 billion at June 30, 2015, from $38.8 billion at December 31, 2014. Average advances outstanding were $50.9 billion in the second quarter of 2015, an 8%increase from $47.0 billion in the second quarter of 2014. Average advances outstanding were $46.8 billion in the first six months of 2015, 2%increase from $46.0 billion in the first six months of 2014.

The increase in advances outstanding was primarily attributable to a $10.7 billion net increase in advances outstanding to the Bank’s top five borrowers and their affiliates. Advances to the top five borrowers increased to $32.1 billion at June 30, 2015, from $21.4 billion at December 31, 2014. Three of these five borrowers increased their borrowings from the Bank during the first six months of 2015, while the remaining two borrowers decreased their borrowings from the Bank during the first six months of 2015. The increase was also attributable to a $0.6 billionincrease in total advances outstanding to the Bank’s other borrowers of varying asset sizes and charter types. (See “Item 1. Financial Statements – Note 7 – Advances” for further information.)

The $11.3 billionincrease in advances outstanding primarily reflected a $9.6 billionincrease in adjustable rate advances and a $1.9 billionincrease in fixed rate advances, partially offset by a $0.2 billiondecrease in variable rate advances.

The components of the advances portfolio at June 30, 2015, and December 31, 2014, are presented in the following table.

(1) 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.

For a discussion of advances credit risk, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Risk Management – Credit Risk – Advances.”

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 $15.6 billion and $12.3 billion as of June 30, 2015, and December 31, 2014, respectively. The increase in the total size of the non-MBS investment portfolio reflects higher balances of short-term securities purchased under agreements to resell, partially offset by lower balances of Federal funds sold and agency debentures.

Cash and Due from Banks – Cash and due from banks was $1.2 billion at June 30, 2015, a $2.7 billiondecrease compared to December 31, 2014. Cash and due from banks is largely composed of cash held at the Federal Reserve Bank of San Francisco and can increase or decrease depending on the availability of other investment opportunities.

Borrowings – Total liabilities (primarily consolidated obligations) funding the advances-related business increased to $61.9 billion at June 30, 2015, from $49.7 billion at December 31, 2014. 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

76

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. 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 June 30, 2015, the notional amount of interest rate exchange agreements associated with the advances-related business totaled $63.5 billion, of which $19.1 billion were hedging advances, $42.4 billion were hedging consolidated obligations, $1.8 billion were economically hedging trading securities and $0.2 billion were offsetting derivatives. At December 31, 2014, the notional amount of interest rate exchange agreements associated with the advances-related business totaled $55.2 billion, of which $17.8 billion were hedging advances, $35.0 billion were hedging consolidated obligations, and $2.4 billion were economically hedging trading securities. 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. For more information, see “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations – Liquidity and Capital Resources” in the Bank’s 2014 Form 10-K.

The Federal Open Market Committee (FOMC) has not changed the target Federal funds rate since December 16, 2008. As of June 30, 2015, rates on 3-month U.S. Treasury bills and 2-year U.S. Treasury notes declined, while the 3-month LIBOR increased and rates on 5-year U.S Treasury notes were unchanged compared with December 31, 2014.

Selected Market Interest Rates
Market Instrument	June 30, 2015		December 31, 2014		June 30, 2014		December 31, 2013
Federal Reserve target rate for overnight Federal funds	0-0.25	%	0-0.25	%	0-0.25	%	0-0.25	%
3-month Treasury bill	0.01		0.03		0.03		0.06
3-month LIBOR	0.28		0.26		0.23		0.25
2-year Treasury note	0.65		0.67		0.46		0.38
5-year Treasury note	1.65		1.65		1.63		1.74

The following table presents a comparison of the average issuance cost of FHLBank System consolidated obligation bonds and discount notes converted to 3-month LIBOR-indexed liabilities through interest rate swaps in the first six months of 2015 and 2014. Increased investor demand in the first six months of 2015 compared to the same period in 2014 contributed to more attractive relative borrowing costs for FHLBank System consolidated obligation bonds and discount notes.

	Spread to LIBOR of Average Cost of Consolidated Obligations for the Six Months Ended
(In basis points)	June 30, 2015	June 30, 2014
Consolidated obligation bonds	–14.0	–12.4
Consolidated obligation discount notes (one month and greater)	–16.6	–15.3

77

Mortgage-Related Business. The mortgage-related business consists of MBS investments, mortgage loans acquired through the Mortgage Partnership Finance (MPF) Program, and the related financing and hedging instruments. 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 June 30, 2015, assets associated with this segment were $18.6 billion (22% of total assets), a decrease of $1.8 billion from $20.4 billion at December 31, 2014 (27% of total assets).

Adjusted net interest income for this segment was $90 million in the second quarter of 2015, a decrease of $15 million, or 14%, from $105 million in the second quarter of 2014. In the first six months of 2015, adjusted net

interest income for this segment was $183 million, a decrease of $32 million, or 15%, from $215 million in the first six months of 2014. The decrease was primarily due to lower average unpaid principal balances of MBS and mortgage loans and reduced spreads on mortgage-related assets, partially offset by the accretion of yield adjustments on certain other-than-temporarily impaired PLRMBS resulting from improvement in expected cash flows.

Adjusted net interest income for this segment represented 66% and 70% of total adjusted net interest income for the second quarter of 2015 and 2014, and 69% and 72% of total adjusted net interest income for the first six months of 2015 and 2014, respectively.

MBS Investments – The Bank’s MBS portfolio was $17.8 billion at June 30, 2015, compared with $19.6 billion at December 31, 2014. During the first six months of 2015, the Bank’s MBS portfolio decreased primarily because of principal repayments totaling $1.8 billion. In the second quarter of 2015, average MBS investments were $18.1 billion, a decrease of $3.4 billion from $21.5 billion in the second quarter of 2014. Average MBS investments were $18.6 billion in the first six months of 2015, a decrease of $3.2 billion from $21.8 billion in the first six months of 2014. For a discussion of the composition of the Bank’s MBS portfolio and the Bank’s OTTI analysis of that portfolio, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Risk Management – Investments” and “Item 1. Financial Statements – Note 6 – Other-Than-Temporary Impairment Analysis.”

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.

MPF Program – Under the MPF Program, the Bank may purchase conventional conforming fixed rate mortgage loans and FHA/VA-insured mortgage loans from members for the Bank’s own portfolio under the Original MPF and MPF Government products. In addition, the Bank may facilitate the purchase of fixed rate mortgage loans from members for concurrent sale to Fannie Mae under the MPF Xtra product. As of June 30, 2015, the Bank had approved six members as participating financial institutions since renewing its participation in the MPF Program in the fourth quarter of 2013.

From May 2002 through October 2006, the Bank purchased conventional conforming fixed rate mortgage loans from its participating financial institutions under the Original MPF and MPF Plus products. Participating members originated or purchased the mortgage loans, credit-enhanced them and sold them to the Bank, and generally retained the servicing of the loans.

Mortgage loan balances decreased to $671 million at June 30, 2015, from $708 million at December 31, 2014, a decrease of $37 million. Average mortgage loans were $675 million in the second quarter of 2015, a decrease of $156 million from $831 million in the second quarter of 2014. Average mortgage loans were $684 million in the first six months of 2015, a decrease of $171 million from $855 million in the first six months of 2014.

78

At June 30, 2015, and December 31, 2014, the Bank held conventional conforming fixed rate mortgage loans purchased under one of two MPF products, MPF Plus or Original MPF, which are described in greater detail in “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations – Risk Management – Credit Risk – MPF Program” in the Bank’s 2014 Form 10-K. The Bank purchased $57 million in eligible loans under the Original MPF product in the first six months of 2015. Mortgage loan balances at June 30, 2015, and December 31, 2014, were as follows:

Mortgage Loan Balances by MPF Product Type
(In millions)	June 30, 2015			December 31, 2014
MPF Plus	$	565		$	653
Original MPF	108			60
Subtotal	673			713
Unamortized premiums	7			6
Unamortized discounts	(9		)	(10		)
Mortgage loans held for portfolio	671			709
Less: Allowance for credit losses	—			(1		)
Mortgage loans held for portfolio, net	$	671		$	708

The Bank performs periodic reviews of its mortgage loan portfolio to identify probable credit losses in the portfolio and to determine the likelihood of collection of the loans in the portfolio. For more information on the Bank’s mortgage loan portfolio, see “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations – Risk Management – Credit Risk – MPF Program” and “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations – Critical Accounting Policies and Estimates – Allowance for Credit Losses – Mortgage Loans Acquired Under the MPF Program” in the Bank’s 2014 Form 10-K.

Borrowings – Total consolidated obligations funding the mortgage-related business decreased$1.8 billion to $18.6 billion at June 30, 2015, from $20.4 billion at December 31, 2014, paralleling the decrease in mortgage portfolio assets. 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.”

The notional amount of interest rate exchange agreements associated with the mortgage-related business totaled $8.0 billion at June 30, 2015, of which $5.8 billion were hedging or were associated with consolidated obligations funding the mortgage portfolio and $2.2 billion were associated with MBS. The notional amount of interest rate exchange agreements associated with the mortgage-related business totaled $7.1 billion at December 31, 2014, of which $4.9 billion were hedging or were associated with consolidated obligations funding the mortgage portfolio and $2.2 billion were associated with MBS.

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 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 2014 Form 10‑K.

79

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 June 30, 2015, and December 31, 2014.

(1) Economic hedges are derivatives that are matched to balance sheet instruments or other derivatives that do not meet the requirements for hedge accounting under the accounting for derivative instruments and hedging activities.

At June 30, 2015, the total notional amount of interest rate exchange agreements outstanding was $71.5 billion, compared with $62.3 billion at December 31, 2014. The $9.2 billionincrease in the notional amount of derivatives during the first six months of 2015 was primarily due to a $8.7 billionincrease in interest rate exchange agreements hedging discount notes and a $1.3 billionincrease in interest rate exchange agreements hedging advances, partially offset by a $0.4 billiondecrease in interest rate exchange agreements hedging consolidated obligation bonds and a

81

$0.6 billiondecrease in interest rate exchange agreements hedging FFCB bonds. The notional amount serves as a basis for calculating periodic interest payments or cash flows received and paid and is not a basis for measuring the amount of credit risk in the transaction.

The following tables categorize the notional amounts and estimated fair values of the Bank’s interest rate exchange agreements, unrealized gains and losses from the related hedged items, and estimated fair value gains and losses from financial instruments carried at fair value by type of accounting treatment and product as of June 30, 2015, and December 31, 2014.

Liquidity and Capital Resources

The Bank’s financial strategies are designed to enable the Bank to expand and contract its assets, liabilities, and capital as membership composition and member credit needs change. The Bank’s liquidity and capital resources are designed to support its financial strategies. The Bank’s primary source of liquidity is its access to the debt capital markets through consolidated obligation issuance. The maintenance of the Bank’s capital resources are governed by its capital plan.

Liquidity

The Bank strives to maintain the liquidity necessary to meet member credit demands, repay maturing consolidated obligations for which it is the primary obligor, and meet other obligations and commitments. The Bank monitors its financial position in an effort to ensure that it has 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—which include commercial paper, certificates of deposit, securities purchased under agreements to resell, and Federal funds sold to highly rated counterparties—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. 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 maintains a contingent liquidity plan to meet its obligations and the liquidity needs of members and housing associates in the event of short-term operational disruptions at the Bank or the Office of Finance or short-term disruptions in the debt capital markets. The Bank has a regulatory contingency 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 of which assume no capital markets access and no reliance on repurchase agreements or the sale of existing HTM and AFS investments. 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.

The Bank actively monitors and manages the structural liquidity risks of the advances business segment, which the Bank defines as maturity mismatches greater than 90 days for sources and uses of funds. 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 and 90-day periods following June 30, 2015, and December 31, 2014. Also shown are additional contingent sources of funds from on-balance sheet collateral available for repurchase agreement borrowings.

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 June 30, 2015, and December 31, 2014. The Bank’s risk-based capital requirement decreased to $2.9 billion at June 30, 2015, from $3.2 billion at December 31, 2014.

Regulatory Capital Requirements
	June 30, 2015						December 31, 2014
(Dollars in millions)	Required			Actual			Required			Actual
Risk-based capital	$	2,923		$	5,546		$	3,231		$	6,356
Total regulatory capital	$	3,438		$	5,546		$	3,032		$	6,356
Total regulatory capital ratio	4.00		%	6.45		%	4.00		%	8.38		%

Leverage ratio	5.00		%	9.68		%	5.00		%	12.58		%

The Bank’s total regulatory capital ratio decreased to 6.45% at June 30, 2015, from 8.38% at December 31, 2014, primarily because of the decrease in regulatory capital resulting from the Bank’s excess capital stock repurchase activity. The Bank repurchased $847 million in excess capital stock in the second quarter of 2015.

On May 29, 2015, the Bank's Excess Stock Repurchase, Retained Earnings, and Dividend Framework (Framework) was revised to reinstate the Bank’s practice of repurchasing the surplus capital stock of all members and the excess capital stock of all nonmember shareholders on a regular quarterly schedule, at the Bank’s discretion and subject to certain statutory and regulatory requirements and to the Bank’s Risk Management Policy and capital plan limitations. Surplus capital stock is defined as any stock holdings in excess of 115% of a member’s minimum stock requirement, and excess capital stock is defined as any stock holdings in excess of a shareholder’s minimum stock requirement. In accordance with the revised Framework, each quarter, Bank management will evaluate and determine the amount of capital stock to be repurchased in that quarter, if any, giving consideration to certain capital metrics and capital management objectives and strategies, and subject to the requirements and limitations mentioned above. In addition, at the Bank’s discretion, some or all of the excess stock held by a shareholder may be repurchased upon request of the shareholder, subject to the requirements and limitations mentioned above. At least 15 calendar days before any repurchase, the Bank will notify shareholders of its intention to repurchase capital stock and of the scheduled repurchase date. On the scheduled repurchase date, the Bank will calculate the amount of stock to be repurchased to ensure that each member and former nonmember shareholder will continue to meet its minimum stock requirement after the repurchase.

The Bank plans to repurchase the surplus capital stock of all members and the excess capital stock of all nonmember shareholders on August 14, 2015.

The Bank’s capital requirements are more fully discussed in “Item 8. Financial Statements and Supplementary Data – Note 15 – Capital” in the Bank’s 2014 Form 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 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 2014 Form 10-K.

Advances. The Bank manages the credit risk of advances and other credit products by setting the credit and collateral terms available to individual members and housing associates based on their creditworthiness and on the quality and value of the assets they pledge as collateral. The Bank also has procedures to assess the mortgage loan quality and documentation standards of institutions that pledge mortgage loan collateral. In addition, the Bank has collateral policies and restricted lending procedures in place to help manage its exposure to institutions that experience difficulty in meeting their capital requirements or other standards of creditworthiness. These credit and collateral policies balance the Bank’s dual goals of meeting the needs of members and housing associates as a reliable source of liquidity and mitigating credit risk by adjusting credit and collateral terms in view of deterioration in creditworthiness. The Bank has never experienced a credit loss on an advance.

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.

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

86

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 June 30, 2015, and December 31, 2014. During the six months ended June 30, 2015, 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 June 30, 2015, the borrowing capacities assigned to U.S. Treasury and agency securities ranged from 55% to 99% of their market value. The borrowing capacities assigned to private-label MBS, which must be rated AAA or AA when initially pledged, generally ranged from 55% to 80% 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 June 30, 2015, and December 31, 2014.

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 or quarterly 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 June 30, 2015, of the loan collateral pledged to the Bank, 37% was pledged by 32 institutions by specific identification, 44% was pledged by 137 institutions under a blanket lien with detailed reporting, and 19% was pledged by 113 institutions under a blanket lien with summary reporting.

As of June 30, 2015, 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: 92% for first lien residential mortgage loans, 91% for multifamily mortgage loans, 88% for commercial mortgage loans, and 82% for second lien residential mortgage loans. The maximum borrowing capacity for small business, small agribusiness, and small farm loans was 50% of the unpaid principal balance, although most of these loans are pledged under blanket lien with summary reporting, with a maximum borrowing capacity of 25%. The highest borrowing capacities are available to borrowers that pledge under a blanket lien with detailed reporting because the detailed loan information allows the Bank to assess the value of the collateral more precisely and because additional collateral is pledged under the blanket lien that may not receive borrowing capacity but may be liquidated to repay advances in the event of default. The Bank may review and change the maximum borrowing capacity for any type of loan collateral at any time.

The table below presents the mortgage loan collateral pledged by all members and by nonmembers with credit outstanding at June 30, 2015, and December 31, 2014.

(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 June 30, 2015, and December 31, 2014, the unpaid principal balance of these loans totaled $13 billion and $14 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 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, Standard & Poor’s, or comparable Fitch Ratings (Fitch) ratings.

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

(2) Includes $100 million and $300 million at June 30, 2015, and December 31, 2014, 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 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

92

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 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.

As of June 30, 2015, the Bank’s unsecured investment credit exposure to U.S. branches and agency offices of foreign commercial banks was limited to Federal funds sold, which represented 92% of the Bank’s total unsecured investment credit exposure in Federal funds sold.

The following table presents the credit ratings of the unsecured investment credit exposures presented by the domicile of the counterparty or the domicile of the counterparty’s parent for U.S. branches and agency offices of foreign commercial banks, based on the lowest of the credit ratings provided by Moody’s, Standard & Poor’s, or comparable Fitch ratings. This table does not reflect the foreign sovereign government’s credit rating. At June 30, 2015, 38% of the carrying value of unsecured investments held by the Bank were rated AA.

These ratings represent the lowest rating available for each unsecured investment owned by the Bank, based on the ratings provided by Moody’s, Standard & Poor’s, or comparable Fitch ratings. The Bank’s internal rating may differ from this rating.

93

(3) Includes $100 million in Federal funds sold to a member counterparty determined by the Bank to have an internal credit rating equivalent to an AA+ rating.

As of June 30, 2015, all of the Bank’s unsecured investments had overnight maturities.

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 mortgage revenue bonds (federally taxable), are collateralized by pools of first lien residential mortgage loans, and are credit-enhanced by bond insurance. The bonds held by the Bank are issued by the California Housing Finance Agency (CalHFA) and insured by either Ambac Assurance Corporation (Ambac), National Public Financial Guarantee (formerly MBIA Insurance Corporation), or Assured Guaranty Municipal Corporation (formerly Financial Security Assurance Incorporated). At June 30, 2015, all of the bonds were rated at least A by Moody’s or Standard & Poor’s.

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 June 30, 2015, 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 June 30, 2015, the Bank’s MBS portfolio was 320% of Bank capital (as determined in accordance with regulations governing the operations of the FHLBanks). The Bank is precluded from purchasing additional MBS investments until its MBS portfolio declines below 300% of Bank capital, but the Bank is not required to sell any previously purchased MBS. The Bank was in compliance with the regulatory limit at the time of its MBS purchases.

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.

The Bank has not purchased any PLRMBS since the first quarter of 2008, and current Bank policy prohibits the purchase of PLRMBS.

At June 30, 2015, PLRMBS representing 34% 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 June 30, 2015, the Bank’s investment in MBS had gross unrealized losses totaling $260 million, most of which were related to PLRMBS. These gross unrealized losses were primarily due to illiquidity in the MBS market, uncertainty about the future condition of the housing and mortgage markets and the economy, and market expectations of the credit performance of loan collateral underlying these securities, causing these assets to be valued at discounts to their acquisition cost.

94

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 June 30, 2015, 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 June 30, 2015, using two third-party models. The first model projects prepayments, default rates, and loss severities on the underlying collateral based on borrower characteristics and the particular attributes of 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 housing price changes for the relevant states and core-based statistical areas (CBSAs), which are 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 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. 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 2.0% to an increase of 8.0% over the 12-month period beginning April 1, 2015. For the vast majority of markets, the projected short-term housing price changes range from an increase of 2.0% to an increase of 5.0%. 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 June 30, 2015:

(1) The credit ratings used by the Bank are based on the lowest of Moody’s, Standard & Poor’s, 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.

The Bank determined that, as of June 30, 2015, the gross unrealized losses on the PLRMBS that have not had an OTTI loss are primarily due to illiquidity in the PLRMBS market, uncertainty about the future condition of the housing and mortgage markets and the economy, and market expectations of the credit performance of loan collateral underlying these securities, which caused these assets to be valued at discounts to their acquisition 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 June 30, 2015, 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 June 30, 2015. 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). 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.

100

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, the Bank has entered into master netting agreements and bilateral security 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 credit rating, as determined by rating agency long-term credit ratings of the counterparty’s debt securities or deposits, or (ii) set at zero (subject to a minimum transfer amount).

The Bank is subject to the risk of potential nonperformance by the counterparties to derivative agreements. Unless the collateral delivery threshold is set at zero, the amount of net unsecured credit exposure that is permissible with respect to each counterparty depends on the credit rating of that counterparty. 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. 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 June 30, 2015.

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 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 use of cleared derivatives mitigates the Bank’s overall credit risk exposure because a central counterparty is substituted for individual counterparties and variation margin is posted daily for changes in the value of cleared derivatives through a clearing agent. The Bank does not anticipate any credit losses on its cleared derivatives as of June 30, 2015.

The following table presents the Bank’s credit exposure to its derivative dealer counterparties at the dates indicated.

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.

102

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 2014 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, and accounting for OTTI 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.

There have been no significant changes in the judgments and assumptions made during the first six months of 2015 in applying the Bank’s critical accounting policies. These policies and the judgments, estimates, and assumptions are also described in “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations – Critical Accounting Policies and Estimates” and “Item 8. Financial Statements and Supplementary Data – Note 1 – Summary of Significant Accounting Policies” in the Bank’s 2014 Form 10-K and in “Item 1. Financial Statements – Note 16 – Fair Value.”

Recent Developments

Annual Designation of Member Director and Independent Director Positions. On May 27, 2015, the Finance Agency designated one member director position for Arizona, six for California, and one for Nevada, effective January 1, 2016, the same as for 2015. In addition, the Finance Agency designated six independent director positions for the Bank for 2016, the same as for 2015. One of the California member director positions, one of the Nevada member director positions, and one of the independent director positions, all with current terms ending December 31, 2015, will be filled through an election of the members located in California (for the California member director position), an election of the members located in Nevada (for the Nevada member director position), and an election of all members of the Bank (for the independent director position). The elections will be held in the fourth quarter of 2015. Each seat will have a four-year term that begins on January 1, 2016.

103

Core Mission Achievement Advisory Bulletin.On July 14, 2015, the Finance Agency issued an advisory bulletin establishing a ratio by which the Finance Agency will assess each FHLBank’s core mission achievement. Core mission achievement is determined using a ratio of primary mission assets, which include advances and acquired member assets (mortgage loans acquired from members), to consolidated obligations. The ratio will be determined at yearend and will be calculated using annual average par values.

The advisory bulletin provides the Finance Agency’s expectations about the content of each FHLBank’s strategic plan based on its ratio, as follows:

• when the ratio is 70% or higher, the strategic plan should include an assessment of the FHLBank’s prospects for maintaining this level;

• when the ratio is between 55% and 70%, the strategic plan should explain the FHLBank’s plan to increase the ratio; and

• when the ratio is below 55%, the strategic plan should include an explanation of the circumstances that caused the ratio to be at that level and detailed plans to increase the ratio. The advisory bulletin provides that if an FHLBank maintains a ratio below 55% over the course of several consecutive reviews, then the FHLBank’s board of directors should consider possible strategic alternatives.

The advisory bulletin is not expected to have a material impact on the Bank.

Off-Balance Sheet Arrangements 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 par value of the outstanding consolidated obligations of the FHLBanks was $852.8 billion at June 30, 2015, and $847.2 billion at December 31, 2014. The par value of the Bank’s participation in consolidated obligations was $79.2 billion at June 30, 2015, and $68.5 billion at December 31, 2014. The Bank had committed to the issuance of $1.4 billion and $3 million in consolidated obligations at June 30, 2015, and December 31, 2014, respectively. For additional information on the Bank’s joint and several contingent liability obligation, see Item 8. Financial Statements and Supplementary Data – Note 20 – Commitments and Contingencies” in the Bank’s 2014 Form 10-K.

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 balance sheet or may be recorded on the Bank’s balance sheet 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 June 30, 2015, the Bank had $177 million in advance commitments and $10.9 billion in standby letters of credit outstanding. At December 31, 2014, the Bank had $126 million in advance commitments and $5.4 billion in standby letters of credit outstanding.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market risk is defined as the risk to the Bank's market value and net portfolio 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

104

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 net portfolio 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, net portfolio 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 and Net Portfolio 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. As explained below, the Bank measures, monitors, and reports on market value of capital sensitivity but does not have a policy limit for this measure.

Since 2008, the Bank has used net portfolio value of capital sensitivity as the primary market value metric for measuring the Bank’s exposure to changes in interest rates and has established a policy limit on net portfolio value of capital sensitivity. This approach uses valuation methods that estimate the value of mortgage-backed securities (MBS) and mortgage loans in alternative interest rate environments based on valuation spreads that existed at the time the Bank acquired the MBS and mortgage loans (acquisition spreads), rather than valuation spreads implied by the current market prices of MBS and mortgage loans (market spreads). Risk metrics based on spreads existing at the time of acquisition of mortgage assets better reflect the market risk of the Bank because the Bank does not intend to sell its mortgage assets and the use of market spreads calculated from estimates of current market prices (which may include large embedded liquidity spreads) would not reflect the actual risks faced by the Bank.

Beginning in the third quarter of 2009, in the case of specific private-label residential mortgage-backed securities (PLRMBS) for which the Bank expects loss of principal in future periods, the par value of the other-than-temporarily impaired security is reduced by the amount of the projected principal shortfall and the asset price is calculated based on the acquisition spread. This approach directly takes into consideration the impact of projected principal (credit) losses from PLRMBS on the net portfolio value of capital, but eliminates the impact of large liquidity spreads inherent in the prior treatment of other-than-temporarily impaired securities.

The Bank’s net portfolio 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 net portfolio 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 net portfolio 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 net portfolio value of capital sensitivity was within the policy limits as of June 30, 2015.

105

To determine the Bank’s estimated risk sensitivities to interest rates for both the market value of capital sensitivity and the net portfolio value of capital sensitivity, the Bank uses a third-party proprietary asset and liability system to calculate estimated net portfolio 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.

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. 

Market Value of Capital Sensitivity Estimated Percentage Change in Market Value of Bank Capital for Various Changes in Interest Rates
Interest Rate Scenario(1)	June 30, 2015		December 31, 2014
+200 basis-point change above current rates	–2.1	%	–2.7	%
+100 basis-point change above current rates	–1.0		–1.2
–100 basis-point change below current rates(2)	+3.4		+2.6
–200 basis-point change below current rates(2)	+8.0		+6.4

(1) Instantaneous change from actual rates at dates indicated.

(2) Interest rates for each maturity are limited to non-negative interest rates.

The Bank’s estimates of the sensitivity of the market value of capital to changes in interest rates as of June 30, 2015, are comparable to the estimates as of December 31, 2014. Interest rates exhibited minor changes. LIBOR interest rates as of June 30, 2015, were 7 basis points higher for the 1-year term, 2 basis points lower for the 5-year term, and 15 basis points lower for the 10-year term. Because interest rates in the declining rate scenarios are limited to non-negative interest rates and the current interest rate environment is so low, the interest rates in the declining rate scenarios cannot decrease to the same extent that the interest rates in the rising rate scenarios can increase.

The table below presents the sensitivity of the net portfolio value of capital (the net value of the Bank’s assets, liabilities, and hedges, with mortgage assets valued using acquisition valuation spreads) to changes in interest rates. The table presents the estimated percentage change in the Bank’s net portfolio value of capital that would be expected to result from changes in interest rates under different interest rate scenarios based on pricing mortgage assets at spreads that existed at the time of purchase rather than at current market spreads. The Bank’s estimates of the sensitivity of the net portfolio value of capital to changes in interest rates as of June 30, 2015, are comparable to the estimates as of December 31, 2014. Interest rates exhibited minor changes. LIBOR interest rates as of June 30, 2015, were 7 basis points higher for the 1-year term, 2 basis points lower for the 5-year term, and 15 basis points higher for the 10-year term. Because interest rates in the declining rate scenarios are limited to non-negative interest rates and the current interest rate environment is so low, the interest rates in the declining rate scenarios cannot decrease to the same extent that the interest rates in the rising rate scenarios can increase.

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 201% as of June 30, 2015.

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.

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. In both the upward and downward shift scenarios, the adjusted return on capital for the projected 12-month horizon is not expected to deteriorate relative to the base case environment.

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

107

Bank level and does not have a policy limit. The Bank’s duration gap was less than one month at June 30, 2015, and at December 31, 2014.

Total Bank Duration Gap Analysis
	June 30, 2015			December 31, 2014
	Amount (In millions)		Duration Gap(1)(2) (In months)	Amount (In millions)		Duration Gap(1)(2) (In months)
Assets	$	85,962	8	$	75,807	10
Liabilities	80,490		8	70,114		10
Net	$	5,472	—	$	5,693	—

(1) Duration gap values include the impact of interest rate exchange agreements.

(2) Because of the current low interest rate environment, the duration gap is estimated using an instantaneous, one-sided parallel change upward of 100 basis points from base case interest rates.

Since duration gap is a measure of market value sensitivity, the impact of large embedded mortgage liquidity spreads on duration gap is the same as described in the analysis in “Total Bank Market Risk – Market Value of Capital Sensitivity and Net Portfolio Value of Capital Sensitivity” above. As a result of the liquidity premium investors require for these assets and the Bank’s intent and ability to hold its mortgage assets to maturity, the Bank does not believe that market value-based sensitivity risk measures provide a fundamental indication of risk.

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 certain regulatory and statutory limits. The strategy to invest 50% of capital in a laddered portfolio of investments

108

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).

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. Net 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.

The Bank purchases a mix of intermediate-term fixed rate and adjustable rate MBS. Generally, purchases of long-term fixed rate MBS have been relatively limited. Any 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 net 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

109

and mortgage prepayment risks associated with the mortgage assets. Debt issued to finance mortgage assets may be 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 and Net Portfolio Value of Capital Sensitivity,” the Bank uses net portfolio 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 net portfolio value of capital sensitivity of the assets, liabilities, and derivatives of the mortgage-related business. In addition, the Bank continues to use 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 measures, monitors, and reports on both the net portfolio value of capital sensitivity and the market value of capital sensitivity attributable to 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 June 30, 2015, and December 31, 2014.

Market Value of Capital Sensitivity Estimated Percentage Change in Market Value of Bank Capital Attributable to the Mortgage-Related Business for Various Changes in Interest Rates
Interest Rate Scenario(1)	June 30, 2015		December 31, 2014
+200 basis-point change	–0.8	%	–1.6	%
+100 basis-point change	–0.4		–0.7
–100 basis-point change(2)	+2.2		+2.0
–200 basis-point change(2)	+5.3		+5.0

(1) Instantaneous change from actual rates at dates indicated.

(2) Interest rates for each maturity are limited to non-negative interest rates.

For the mortgage-related business, the Bank’s estimates of the sensitivity of the market value of capital to changes in interest rates improved as of June 30, 2015, compared to the estimates as of December 31, 2014. The improvement in sensitivity was due primarily to a smaller mortgage-related portfolio and the impact of improvements in housing prices and reduced volatility on the timing of cash flows. Interest rates exhibited minor changes. LIBOR interest rates as of June 30, 2015, were 7 basis points higher for the 1-year term, 2 basis points lower for the 5-year term, and 15 basis points higher for the 10-year term. Because interest rates in the declining rate scenarios are limited to non-negative interest rates and the current interest rate environment is so low, the interest rates in the declining rate scenarios cannot decrease to the same extent that the interest rates in the rising rate scenarios can increase.

The Bank’s interest rate risk policies and guidelines for the mortgage-related business address the net portfolio value of capital sensitivity of the assets, liabilities, and derivatives of the mortgage-related business. The following table presents results of the estimated net portfolio value of capital sensitivity analysis attributable to the mortgage-related business as of June 30, 2015, and December 31, 2014. The table presents the estimated percentage change in the value of Bank capital attributable to the mortgage-related business that would be expected to result from changes in interest rates under different interest rate scenarios based on pricing mortgage assets at spreads that existed at the time of purchase rather than current market spreads.

ITEM 4. CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

The senior management of the Federal Home Loan Bank of San Francisco (Bank) is responsible for establishing and maintaining a system of disclosure controls and procedures designed to ensure that information required to be disclosed by the Bank in the reports filed or submitted under the Securities Exchange Act of 1934 (1934 Act) is recorded, processed, summarized, and reported within the time periods specified in the rules and forms of the Securities and Exchange Commission. The Bank’s disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by the Bank in the reports that it files or submits under the 1934 Act is accumulated and communicated to the Bank’s management, including its principal executive officer or officers and principal financial officer or officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. In designing and evaluating the Bank’s disclosure controls and procedures, the Bank’s management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and the Bank’s management necessarily is required to apply its judgment in evaluating the cost-benefit relationship of controls and procedures.

Management of the Bank has evaluated the effectiveness of the design and operation of its disclosure controls and procedures with the participation of the president and chief executive officer, executive vice president and chief operating 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, executive vice president and chief operating 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 June 30, 2015, 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.

111

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.

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

The Federal Home Loan Bank of San Francisco (Bank) may be subject to various legal proceedings arising in the normal course of business.

In 2010, the Bank filed two complaints in the Superior Court of the State of California, County of San Francisco (San Francisco Superior Court), relating to the purchase of private-label residential mortgage-backed securities (PLRMBS). The Bank seeks rescission, and asserts claims for and violations of the California Corporate Securities Act and common law rescission of contract.

For a further discussion of this litigation, see “Part I. Item 3. Legal Proceedings” in the Bank’s Annual Report on Form 10-K for the year ended December 31, 2014.

After consultation with legal counsel, the Bank is not aware of any other legal proceedings that are expected to have a material effect on its financial condition or results of operations or that are otherwise material to the Bank.

ITEM 1A. RISK FACTORS

For a discussion of risk factors, see “Part I. Item 1A. Risk Factors” in the Bank’s 2014 Form 10-K. There have been no material changes from the risk factors disclosed in the “Part I. Item 1A. Risk Factors” section of the Bank’s 2014 Form 10-K.

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies

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 June 30, 2015, 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 $852,783 at June 30, 2015, and $847,175 at December 31, 2014. The par value of the Bank’s participation in consolidated obligations was $79,210 at June 30, 2015, and $68,538 at December 31, 2014. For more information on the joint and several liability regulation, see “Item 8. Financial Statements and Supplementary Data – Note 20 – Commitments and Contingencies” in the Bank’s 2014 Form 10-K.

Off-balance sheet commitments as of June 30, 2015, and December 31, 2014, were as follows:

	June 30, 2015						December 31, 2014
	Expire Within One Year		Expire After One Year		Total		Expire Within One Year		Expire After One Year		Total
Standby letters of credit outstanding	$	7,671	$	3,213	$	10,884	$	2,699	$	2,711	$	5,410
Commitments to fund advances(1)	174		3		177		121		5		126
Commitments to issue consolidated obligation discount notes, par	800		—		800		3		—		3
Commitments to issue consolidated obligation bonds, par(2)	595		—		595		—		—		—
Commitments to purchase mortgage loans	7		—		7		—		—		—

(1) AtJune 30, 2015, and December 31, 2014, $100 of the commitments to fund additional advances were hedged with associated interest rate swaps.

(2) AtJune 30, 2015, all of the unsettled consolidated obligation bonds were hedged with associated interest rate swaps.

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 44 days to 15 years, including a final expiration in 2030. The Bank monitors the creditworthiness of members that have standby letters of credit. In addition, standby letters of credit are fully collateralized. As a result, the Bank determined that it was not necessary to record any allowance for losses on these commitments at June 30, 2015, and December 31, 2014.

The value of the Bank’s obligations related to standby letters of credit is recorded in other liabilities and amounted to $16 at June 30, 2015, and $12 at December 31, 2014. 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 June 30, 2015, and December 31, 2014.

Commitments to fund advances totaled $177 at June 30, 2015, and $126 at December 31, 2014. 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 June 30, 2015, and December 31, 2014.

The Bank may enter into commitments that unconditionally obligate it to purchase mortgage loans from its members. Commitments are generally for periods not exceeding 30 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 with its members. The Bank enters into master agreements with netting provisions and into bilateral security 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. As of June 30, 2015, the Bank had pledged total cash collateral of $727 to counterparties and the clearing house that had market risk exposure to the Bank related to derivatives. As of December 31, 2014, the Bank had pledged total collateral of $502, including securities with a de minimis carrying value, all of which may be sold or repledged, and cash collateral of $502 to counterparties and the clearing house that had market risk exposure to the Bank related to derivatives.

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.

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, 2015. 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, 2014 (2014 Form 10‑K).

Use of Estimates. The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP) requires management to make a number of judgments, estimates, and assumptions that may affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities, and the reported amounts of income, expenses, gains, and losses during the reporting period. The most significant of these estimates include estimating 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.

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 June 30, 2015, 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.

Gains on Litigation Settlements, Net. Litigation settlement gains, net of related legal expenses, are recorded in Other Income/(Loss) in “Gains on litigation settlements, net” in the Statements of Income. A litigation settlement gain is considered realized and recorded when the Bank receives cash or assets that are readily convertible to known amounts of cash or claims to cash. In addition, a litigation settlement gain is considered realizable and recorded when the Bank enters into a signed agreement that is not subject to appeal, where the counterparty has the ability to pay, and the amount to be received can be reasonably estimated. Prior to being realized or realizable, the Bank considers potential litigation settlement gains to be gain contingencies, and therefore they are not recorded in the Statements of Income. The related legal expenses are contingent-based fees and are only incurred and recorded upon a litigation settlement gain.

Descriptions of the Bank’s significant accounting policies are included in “Item 8. Financial Statements and Supplementary Data – Note 1 – Summary of Significant Accounting Policies” in the Bank’s 2014 Form 10-K. Other changes to these policies as of June 30, 2015, are discussed in Note 2 – Recently Issued and Adopted Accounting Guidance.

Accounting Policies [Line Items]

Fair Value of Financial Instruments, Policy [Policy Text Block]

Investment Securities – MBS – To value its MBS, the Bank obtains prices from four 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.

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.

Consolidated Obligations –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 inputs for measuring the fair value of consolidated obligation bonds are market-based CO Curve inputs obtained from the Office of Finance. The Office of Finance constructs the CO Curve using the Treasury yield curve as a base curve, which may be adjusted by indicative 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 trades or secondary market activity. For consolidated obligation bonds with embedded options, the Bank also obtains market-observable quotes and inputs from derivative dealers. 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).

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 have been significantly affected during the reporting period by changes in the instrument-specific credit risk.

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 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 security 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 credit rating, as determined by rating agency long-term credit ratings of the counterparty’s debt securities or deposits, 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 strict 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.

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: (1) quoted prices for similar assets or liabilities in active markets; (2) quoted prices for identical or similar assets or liabilities in markets that are not active; (3) inputs other than quoted prices that are observable for the asset or liability (e.g., interest rates and yield curves that are observable at commonly quoted intervals, and implied volatilities); and (4) inputs that are derived principally from or corroborated by observable market data by correlation or other means.

• Level 3 – Unobservable inputs for the asset or liability.

A financial instrument’s categorization within the valuation hierarchy is based on the lowest level of input that is significant to the fair value measurement.

The following assets and liabilities, including those for which the Bank has elected the fair value option, are carried at fair value on the Statements of Condition as of June 30, 2015:

• Trading securities

• AFS securities

• Certain advances

• Derivative assets and liabilities

• Certain consolidated obligation bonds

• Certain other assets

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 –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 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 from derivative dealers for complex advances. 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.

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.

Investment Securities – Certificates of Deposit –The estimated fair values of these investments are determined by calculating the present value of expected cash flows and reducing the amount for accrued interest receivable, using market-observable inputs as of the last business day of the period or using industry standard analytical models and certain actual and estimated market information. The discount rates used in these calculations are the replacement rates for comparable instruments with similar terms.

Cash and Due from Banks–The estimated fair value equals the carrying value.

Federal Funds Sold and Securities Purchased Under Agreements to Resell – The estimated fair value 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 calculations are the replacement rates for comparable instruments with similar terms.

Loans to 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.

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 in fair value does not include changes in instrument-specific credit risk.

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.

The Bank calculated a market-implied yield for each of its PLRMBS using the estimated fair value derived from the process described above and the security’s projected cash flows from the Bank’s OTTI process and compared the market-implied yield to the yields for comparable securities according to dealers and other third-party sources to the extent comparable market yield data was available. This analysis did not indicate that any adjustments to the fair value estimates were necessary.

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; 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; and prepayment assumptions.

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 2014 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.

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.

Use of Estimates, Policy [Policy Text Block]

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.

Repurchase and Resale Agreements Policy [Policy Text Block]

Securities purchased under agreements to resell are considered collateralized financing arrangements and effectively represent short-term loans to counterparties that are considered by the Bank to be of investment quality, which are classified as assets in the Statements of Condition. Securities purchased under agreements to resell are held in safekeeping in the name of the Bank by third-party custodians approved by the Bank. In accordance with the terms of these loans, if the market value of the underlying securities decreases below the market value required as collateral, the counterparty must place an equivalent amount of additional securities as collateral or remit an equivalent amount of cash.

Investment, Policy [Policy Text Block]

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 meet neither 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 2.0% to an increase of 8.0% over the 12-month period beginning April 1, 2015. For the vast majority of markets, the projected short-term housing price changes range from an increase of 2.0% to an increase of 5.0%. Thereafter, a unique path is projected for each geographic area based on an internally developed framework derived from historical data.

Derivatives, Offsetting Fair Value Amounts, Policy [Policy Text Block]

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.

The Bank may present derivative instruments, related cash collateral received or pledged, and associated accrued interest by clearing agent or by counterparty when the netting requirements have been met.

Consolidation, Variable Interest Entity, Policy [Policy Text Block]

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 June 30, 2015, 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.

Loans and Leases Receivable, Allowance for Loan Losses Policy [Policy Text Block]

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 a credit risk exposure at the time of purchase equivalent to assets rated AA, taking into 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.

The Bank calculates its estimated allowance for credit losses on mortgage loans acquired under the Original MPF and MPF Plus products as described below. Effective January 1, 2015, the Bank implemented the accounting requirements of regulatory Advisory Bulletin 2012-02. As a result, for any mortgage loans that are more than 180 days past due and that have any outstanding balance in excess of the fair value of the property, less cost to sell, this excess is charged off as a loss by the end of the month in which the applicable time period elapses. Likewise, when a borrower is in bankruptcy, loans are written down to the fair value of the collateral, less cost to sell, in general within 60 days of receipt of the notification of filing from the bankruptcy court, unless it can be clearly demonstrated and documented that repayment is likely to occur. As a result of these charge-offs during the first six months of 2015, the corresponding Allowance for Credit Losses on MPF Loans, which had previously provided for most of these expected losses, was reduced accordingly.

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.

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.

Loans and Leases Receivable, Troubled Debt Restructuring Policy [Policy Text Block]

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 Bank’s TDRs of MPF loans primarily involve modifying the borrower’s monthly payment for a period of up to 36 months to reflect a housing expense ratio that is no more than 31% of the borrower’s qualifying monthly income. The outstanding principal balance is re-amortized to reflect a principal and interest payment for a term not to exceed 40 years from the original note date and a housing expense ratio not to exceed 31%. This would result in a balloon payment at the original maturity date of the loan because the maturity date and number of remaining monthly payments are not adjusted. If the 31% ratio is still not achieved through re-amortization, the interest rate is reduced in 0.125% increments below the original note rate, to a floor rate of 3.00%, resulting in reduced principal and interest payments, for the temporary payment modification period of up to 36 months, until the 31% housing expense ratio is met. 

Finance, Loan and Lease Receivables, Held-for-investment, Allowance and Nonperforming Loans, Allowance Policy [Policy Text Block]

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.

Derivatives, Policy [Policy Text Block]

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.

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 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.

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 derivatives receives 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.

Derivatives, Hedge Discontinuances [Policy Text Block]

The Bank discontinues hedge accounting prospectively when: (i) it determines that the derivative is no longer effective in offsetting changes in the fair value or cash flows 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.

Derivatives, Embedded Derivatives [Policy Text Block]

The Bank did not have any bonds 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 June 30, 2015, or December 31, 2014. The Bank has generally elected to account for bonds with embedded features under the fair value option, and these bonds are carried at fair value on the Statements of Condition.

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).

Derivatives, Methods of Accounting, Hedging Derivatives [Policy Text Block]

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.

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.

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 and the issuance of consolidated obligation bonds to create variable rate structures. The interest rate exchange agreements are generally executed at 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 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 derivative 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 that may be executed with members (with the Bank serving as an intermediary) or 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, (ii) an economic hedge of a specific asset or liability, or (iii) an intermediary transaction for members.

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 indexed to LIBOR.

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.

The Bank documents all relationships between derivative hedging instruments and hedged items, its risk management objectives and strategies for undertaking various hedge transactions, and its method of assessing effectiveness. This process includes linking all derivatives that are designated as fair value or cash flow hedges to: (i) assets and liabilities on the balance sheet, (ii) firm commitments, or (iii) forecasted transactions. The Bank also formally assesses (both at the hedge’s inception and on an ongoing basis) whether the derivatives that are used in hedging transactions have been effective in offsetting changes in the fair value or cash flows of hedged items attributable to the hedged risk and whether those derivatives may be expected to remain effective 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’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 mortgages with lower-yielding assets and the Bank’s higher funding costs are not reduced accordingly.

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.

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 generally do not meet the requirements for fair value hedge accounting treatment.

The Bank is subject to credit risk as a result of the risk of potential nonperformance by counterparties to the derivative 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 and credit guidelines and Finance Agency regulations. The Bank also requires collateral agreements with collateral delivery thresholds on all uncleared derivatives. In addition, collateral related to derivative transactions with member institutions includes collateral pledged to the Bank, as evidenced by the Advances and Security Agreement, which may be held by the member institution for the benefit of the Bank.

For cleared derivatives, the clearinghouse is the Bank’s counterparty. The requirement that the Bank post initial and variation margin through the 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 and variation margin is posted daily for changes in the value of cleared derivatives through a clearing agent. 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 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 Bank’s agreements for uncleared derivative transactions contain provisions that link the Bank’s credit rating from Moody’s and Standard & Poor’s to various rights and obligations. Certain of these derivative agreements provide that, if the Bank’s long-term debt rating falls below A3/A- (and in one agreement, below A2/A), 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. In addition, under some of its agreements for uncleared derivative transactions, the amount of collateral that the Bank is required to deliver to a counterparty depends on the Bank’s credit rating.

The Bank offers a wide array 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 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 receives fair value option accounting treatment.

Deposits, Policy [Policy Text Block]

The Bank maintains demand deposit accounts that are directly related to the extension of credit to members and offers short-term deposit programs to members and qualifying nonmembers. In addition, a member that services mortgage loans may deposit in the Bank funds collected in connection with the mortgage loans, pending disbursement of these funds to the owners of the mortgage loans. The Bank classifies these types of deposits as non-interest-bearing deposits.

Stockholders' Equity, Policy [Policy Text Block]

The Bank’s Excess Stock Repurchase, Retained Earnings, and Dividend 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.

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 201% as of June 30, 2015.

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.

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.

Segment Reporting, Policy [Policy Text Block]

The Bank uses an analysis of financial performance based on the balances 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 to determine the allocation of resources to these two major 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.

Fair Value Transfer, Policy [Policy Text Block]

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.

Subsequent Events, Policy [Policy Text Block]

There were no other material subsequent events identified, subsequent to June 30, 2015, until the time of the Form 10-Q filing with the Securities and Exchange Commission.

New Accounting Pronouncements, Policy [Policy Text Block]

Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement. On April 15, 2015, the Financial Accounting Standards Board (FASB) issued amendments to clarify a customer’s accounting for fees paid in a cloud computing arrangement. The amendments provide guidance to customers on determining whether a cloud computing arrangement includes a software license that should be accounted for as internal-use software. If the arrangement does not contain a software license, it would be accounted for as a service contract. This guidance becomes effective for the Bank for the interim and annual periods beginning after December 15, 2015, and early adoption is permitted. The Bank can elect to adopt the amendments either (1) prospectively to all arrangements entered into or materially modified after the effective date or (2) retrospectively. The Bankis in the process of evaluating this guidance and its effect on the Bank’s financial condition, results of operations, and cash flows.

Simplifying the Presentation of Debt Issuance Costs. On April 7, 2015, the FASB issued guidance to simplify the presentation of debt issuance costs. This guidance requires that debt issuance costs related to a recognized debt liability be presented on the statement of condition as a direct deduction from the carrying amount of that debt liability, consistent with the presentation of debt discounts. The adoption of this guidance will result in a reclassification of debt issuance costs from other assets to consolidated obligations on the Bank’s Statements of Condition. This guidance becomes effective for the Bank for the interim and annual periods beginning after December 15, 2015, and early adoption is permitted for financial statements that have not been previously issued. The guidance is required to be applied on a retrospective basis to each individual period presented on the statement of condition. The Bank is in the process of evaluating this guidance and its effect on the Bank’s financial condition, results of operations, and cash flows.

Amendments to the Consolidation Guidance. On February 18, 2015, the FASB issued guidance intended to enhance consolidation guidance for legal entities such as limited partnerships, limited liability corporations, and securitization structures (collateralized debt obligations, collateralized loan obligations, and mortgage-backed security transactions). The new guidance primarily focuses on the following:

• Placing more emphasis on risk of loss when determining a controlling financial interest. A reporting organization may no longer have to consolidate a legal entity in certain circumstances based solely on its fee arrangement, when certain criteria are met.

• Reducing the frequency of the application of related-party guidance when determining a controlling financial interest in a VIE.

• Changing consolidation conclusions for public and private companies in several industries that typically make use of limited partnerships or VIEs.

This guidance becomes effective for the Bank for interim and annual periods beginning after December 15, 2015, and early adoption is permitted, including adoption in an interim period. This guidance is not expected to affect the Bank’s financial condition, results of operations, and cash flows.

Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern.On August 27, 2014, the FASB issued guidance about management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosures. This guidance requires management to perform interim and annual assessments of an entity’s ability to continue as a going concern within one year after the date the financial statements are issued or within one year after the financial statements are available to be issued, when applicable. Substantial doubt exists if it is probable that the entity will be unable to meet its obligations for the assessed period. This guidance becomes effective for the Bank for the interim and annual periods ending after December 15, 2016, and early application is permitted. This guidance is not expected to affect the Bank’s financial condition, results of operations, and cash flows.

Classification of Certain Government-Guaranteed Mortgage Loans upon Foreclosure.On August 8, 2014, the FASB issued amended guidance relating to the classification and measurement of certain government-guaranteed mortgage loans upon foreclosure. The amendments in this guidance require that a mortgage loan be derecognized and that a separate other receivable be recognized upon foreclosure if certain conditions are met. This guidance became effective for the Bank for the interim and annual periods beginning on January 1, 2015, and was adopted prospectively. The adoption of this guidance did not affect the Bank’s financial condition, results of operations, or cash flows.

Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures.On June 12, 2014, the FASB issued amended guidance for repurchase-to-maturity transactions and repurchase agreements executed as repurchase financings. Specifically, this guidance requires entities to account for (1) repurchase-to-maturity transactions as secured borrowings rather than as sales with forward repurchase agreements; and (2) repurchase agreements executed contemporaneously with the initial transfer of the underlying financial asset with the same counterparty as separate transactions only. In addition, this guidance requires a transferor to disclose additional information about certain transactions, including those in which it retains substantially all of the exposure to the economic returns of the underlying transferred asset over the transaction’s term. This guidance became effective for the Bank for the interim and annual periods beginning on January 1, 2015. The changes in accounting for transactions outstanding on the effective date are required to be presented on a cumulative-effect basis. The adoption of this guidance did not affect the Bank’s financial condition, results of operations, 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 entities to use in accounting for 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, or lease contracts.

This guidance becomes effective for the interim and annual reporting periods beginning after December 15, 2016, and early application is not permitted. The guidance provides the entities with the option of using the following two methods upon adoption: a full retrospective method, applied retrospectively to each prior reporting period presented; or a transition method, with the cumulative effect of retrospectively applying this guidance recognized at the date of initial application. The Bank is in the process of evaluating this guidance and its effect on the Bank’s financial condition, results of operations, and cash flows, but it is not expected to be material.

Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure. On January 17, 2014, theFASB issued guidance clarifying when consumer mortgage loans collateralized by real estate should be reclassified to REO. Specifically, these collateralized mortgage loans should be reclassified to REO when either the creditor obtains legal title to the residential real estate property upon completion of a foreclosure or the borrower conveys all interest in the residential real estate property to the creditor to satisfy the loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. The guidance became effective for interim and annual periods beginning on January 1, 2015, and was adopted prospectively. The adoption of this guidance did not affect the Bank’s financial condition, results of operations, or cash flows.

Regulatory Guidance

Framework for Adversely Classifying Loans, Other Real Estate Owned, and Other Assets and Listing Assets for Special Mention.On April 9, 2012, the Finance Agency issued Advisory Bulletin 2012-02, Framework for Adversely Classifying Loans, Other Real Estate Owned, and Other Assets and Listing Assets for Special Mention (AB 2012-02). The guidance establishes a standard and uniform methodology for classifying loans, other real estate owned, and certain other assets (excluding investment securities) and prescribes the timing of asset charge-offs based on these classifications. The guidance is generally consistent with the Uniform Retail Credit Classification and Account Management Policy issued by the federal banking regulators in June 2000. The Bank implemented the asset classification provisions as of January 1, 2014, and this adoption did not have any impact on the Bank’s financial condition, results of operations, or cash flows. The charge-off provisions were implemented on January 1, 2015, and resulted in a $1 charge-off to the Bank’s allowance for credit losses on the mortgage loan portfolio for the six months ended June 30, 2015. The adoption of these charge-off provisions did not have a material effect on the Bank’s financial condition, results of operations, or cash flows.

Federal Home Loan Bank Advances, Prepayment Fees, Policy [Policy Text Block]

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

Revenue Recognition Accounting Policy, Gross and Net Revenue Disclosure [Policy Text Block]

Litigation settlement gains, net of related legal expenses, are recorded in Other Income/(Loss) in “Gains on litigation settlements, net” in the Statements of Income. A litigation settlement gain is considered realized and recorded when the Bank receives cash or assets that are readily convertible to known amounts of cash or claims to cash. In addition, a litigation settlement gain is considered realizable and recorded when the Bank enters into a signed agreement that is not subject to appeal, where the counterparty has the ability to pay, and the amount to be received can be reasonably estimated. Prior to being realized or realizable, the Bank considers potential litigation settlement gains to be gain contingencies, and therefore they are not recorded in the Statements of Income. The related legal expenses are contingent-based fees and are only incurred and recorded upon a litigation settlement gain.

Loans and Leases Receivable, Allowance for Loan Losses Policy [Policy Text Block]

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.

Loans and Leases Receivable, Allowance for Loan Losses Policy [Policy Text Block]

If an agreement to resell is deemed to be impaired, the difference between the fair value of the collateral and the amortized cost of the agreement is charged to earnings. Based upon the collateral held as security, the Bank determined that no allowance for credit losses was needed for the term securities purchased under agreements to resell at June 30, 2015.

PLRMBS [Member]

Accounting Policies [Line Items]

Investment, Policy [Policy Text Block]

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.

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 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, 2015. 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 six months ended June 30, 2014.

Segment Reporting [Abstract]

Segment Information

Segment Information

The Bank uses an analysis of financial performance based on the balances 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 to determine the allocation of resources to these two major 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 2014 Form 10-K.

The following table presents the Bank’s adjusted net interest income by operating segment and reconciles total adjusted net interest income to income before the AHP assessment for the three and six months ended June 30, 2015 and 2014.

Fair Value Disclosures [Abstract]

Fair Value

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 June 30, 2015, and December 31, 2014. 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. 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 June 30, 2015, and December 31, 2014.

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: (1) quoted prices for similar assets or liabilities in active markets; (2) quoted prices for identical or similar assets or liabilities in markets that are not active; (3) inputs other than quoted prices that are observable for the asset or liability (e.g., interest rates and yield curves that are observable at commonly quoted intervals, and implied volatilities); and (4) inputs that are derived principally from or corroborated by observable market data by correlation or other means.

• Level 3 – Unobservable inputs for the asset or liability.

A financial instrument’s categorization within the valuation hierarchy is based on the lowest level of input that is significant to the fair value measurement.

The following assets and liabilities, including those for which the Bank has elected the fair value option, are carried at fair value on the Statements of Condition as of June 30, 2015:

• 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 and Due from Banks–The estimated fair value equals the carrying value.

Federal Funds Sold and Securities Purchased Under Agreements to Resell – The estimated fair value 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 calculations are the replacement rates for comparable instruments with similar terms.

Investment Securities – Certificates of Deposit –The estimated fair values of these investments are determined by calculating the present value of expected cash flows and reducing the amount for accrued interest receivable, using market-observable inputs as of the last business day of the period or using industry standard analytical models and certain actual and estimated market information. The discount rates used in these calculations are the replacement rates for comparable instruments with similar terms.

Investment Securities – MBS – To value its MBS, the Bank obtains prices from four 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.

At least annually, the Bank conducts reviews of the four 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 four vendor prices are received, the average of the middle two prices is the median price; 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 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 June 30, 2015, four vendor prices were received for most of the Bank’s MBS, and the fair value estimates for most of those securities were determined by averaging the four 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 or significant yield variances, 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.

As an additional step, the Bank reviewed the fair value estimates of its PLRMBS as of June 30, 2015, for reasonableness using a market-implied yield test. The Bank calculated a market-implied yield for each of its PLRMBS using the estimated fair value derived from the process described above and the security’s projected cash flows from the Bank’s OTTI process and compared the market-implied yield to the yields for comparable securities according to dealers and other third-party sources to the extent comparable market yield data was available. This analysis did not indicate that any adjustments to the fair value estimates were necessary.

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 –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 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 from derivative dealers for complex advances. 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 for creditworthiness primarily because advances were fully collateralized.

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 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; 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; and prepayment assumptions.

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 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 security 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 credit rating, as determined by rating agency long-term credit ratings of the counterparty’s debt securities or deposits, 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 strict 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.

Consolidated Obligations –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 inputs for measuring the fair value of consolidated obligation bonds are market-based CO Curve inputs obtained from the Office of Finance. The Office of Finance constructs the CO Curve using the Treasury yield curve as a base curve, which may be adjusted by indicative 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 trades or secondary market activity. For consolidated obligation bonds with embedded options, the Bank also obtains market-observable quotes and inputs from derivative dealers. 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).

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 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.

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 Measurements. The tables below present the fair value of assets and liabilities, which are recorded on a recurring or nonrecurring basis at June 30, 2015, and December 31, 2014, by level within the fair value hierarchy.

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 2014 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 table summarizes the activity related to financial assets and liabilities for which the Bank elected the fair value option during the three and six months ended June 30, 2015 and 2014:

	Three Months Ended
	June 30, 2015						June 30, 2014

Balance, end of the period	$	4,978		$	6,203		$	6,341		$	7,080

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 in fair value does not include changes in instrument-specific credit risk. For advances and consolidated obligations recorded under the fair value option, the Bank determined that no adjustments to the fair values of these instruments for instrument-specific credit risk were necessary for the three and six months ended June 30, 2015 and 2014.

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 June 30, 2015, and December 31, 2014:

	At June 30, 2015							At December 31, 2014
	Principal Balance		Fair Value		Fair Value Over/(Under) Principal Balance			Principal Balance		Fair Value		Fair Value Over/(Under) Principal Balance
Advances(1)	$	4,920	$	4,978	$	58		$	5,048	$	5,137	$	89
Consolidated obligation bonds	6,220		6,203		(17		)	6,748		6,717		(31		)

(1) At June 30, 2015, and December 31, 2014, none of these advances were 90 days or more past due or had been placed on nonaccrual status.

Loans and Leases Receivable, Allowance [Abstract]

Allowance for Credit Losses

Allowance for Credit Losses

The Bank has established an allowance methodology for each of its portfolio segments: 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 2014 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 June 30, 2015, and December 31, 2014, 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 six months ended June 30, 2015, or during 2014.

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 June 30, 2015, 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.

Nomember institutions were placed into receivershipduring the first six months of 2015 or from July 1 to July 31, 2015.

Mortgage Loans Held for Portfolio. The following table presents information on delinquent mortgage loans as of June 30, 2015, and December 31, 2014.

(1) The recorded investment in a loan is the unpaid principal balance of the loan, adjusted for accrued interest, net deferred loan fees or costs, unamortized premiums or discounts, and direct write-downs. The recorded investment is not net of any valuation allowance.

(2) Includes loans for which the servicer has reported a decision to foreclose or to pursue a similar alternative, such as deed-in-lieu. Loans in process of foreclosure are included in past due or current loans depending on their delinquency status.

(3) Represents loans that are 90 days or more past due or in the process of foreclosure as a percentage of the recorded investment of total mortgage loans outstanding.

The allowance for credit losses on the mortgage loan portfolio was as follows:

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 a credit risk exposure at the time of purchase equivalent to assets rated AA, taking into 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.

The Bank calculates its estimated allowance for credit losses on mortgage loans acquired under the Original MPF and MPF Plus products as described below. Effective January 1, 2015, the Bank implemented the accounting requirements of regulatory Advisory Bulletin 2012-02. As a result, for any mortgage loans that are more than 180 days past due and that have any outstanding balance in excess of the fair value of the property, less cost to sell, this excess is charged off as a loss by the end of the month in which the applicable time period elapses. Likewise, when a borrower is in bankruptcy, loans are written down to the fair value of the collateral, less cost to sell, in general within 60 days of receipt of the notification of filing from the bankruptcy court, unless it can be clearly demonstrated and documented that repayment is likely to occur. As a result of these charge-offs during the first six months of 2015, the corresponding Allowance for Credit Losses on MPF Loans, which had previously provided for most of these expected losses, was reduced accordingly.

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 an allowance for credit losses for Original MPF loans totaling a de minimis amount as of June 30, 2015, and December 31, 2014, and for MPF Plus loans totaling a de minimis amount as of June 30, 2015, and $1 as of December 31, 2014.

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 Original MPF loans totaling a de minimis amount as of June 30, 2015, and December 31, 2014, and for MPF Plus loans totaling a de minimis amount as of June 30, 2015, and December 31, 2014.

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 Bank’s TDRs of MPF loans primarily involve modifying the borrower’s monthly payment for a period of up to 36 months to reflect a housing expense ratio that is no more than 31% of the borrower’s qualifying monthly income. The outstanding principal balance is re-amortized to reflect a principal and interest payment for a term not to exceed 40 years from the original note date and a housing expense ratio not to exceed 31%. This would result in a balloon payment at the original maturity date of the loan because the maturity date and number of remaining monthly payments are not adjusted. If the 31% ratio is still not achieved through re-amortization, the interest rate is reduced in 0.125% increments below the original note rate, to a floor rate of 3.00%, resulting in reduced principal and interest payments, for the temporary payment modification period of up to 36 months, until the 31% housing expense ratio is met. The recorded investment of the Bank's nonperforming MPFloans classified as TDRs totaled $2.7 as of June 30, 2015, and $2.3 as of December 31, 2014.

Term Securities Purchased Under Agreements to Resell. Securities purchased under agreements to resell are considered collateralized financing arrangements and effectively represent short-term loans to counterparties that are considered by the Bank to be of investment quality, which are classified as assets in the Statements of Condition. Securities purchased under agreements to resell are held in safekeeping in the name of the Bank by third-party custodians approved by the Bank. In accordance with the terms of these loans, if the market value of the underlying securities decreases below the market value required as collateral, the counterparty must place an equivalent amount of additional securities as collateral or remit an equivalent amount of cash. If an agreement to resell is deemed to be impaired, the difference between the fair value of the collateral and the amortized cost of the agreement is charged to earnings. Based upon the collateral held as security, the Bank determined that no allowance for credit losses was needed for the term securities purchased under agreements to resell at June 30, 2015. The Bank did not have any term securities purchased under agreements to resell at December 31, 2014.

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 June 30, 2015, and December 31, 2014, were repaid or are expected to be repaid according to the contractual terms.

Deposits

The Bank maintains demand deposit accounts that are directly related to the extension of credit to members and offers short-term deposit programs to members and qualifying nonmembers. In addition, a member that services mortgage loans may deposit in the Bank funds collected in connection with the mortgage loans, pending disbursement of these funds to the owners of the mortgage loans. The Bank classifies these types of deposits as non-interest-bearing deposits.

Deposits as of June 30, 2015, and December 31, 2014, were as follows:

	June 30, 2015		December 31, 2014
Interest-bearing deposits:
Demand and overnight	$	486	$	159
Total interest-bearing deposits	486		159
Non-interest-bearing deposits	2		1
Total	$	488	$	160

Interest Rate Payment Terms. Deposits classified as demand, overnight, and other pay interest based on a daily interest rate. Term deposits pay interest based on a fixed rate determined at the issuance of the deposit. Interest rate payment terms for deposits at June 30, 2015, and December 31, 2014, are detailed in the following table:

	June 30, 2015				December 31, 2014

Interest-bearing deposits – Adjustable rate	$	486	0.01	%	$	159	0.01	%

(1) Amortized cost includes unpaid principal balance, unamortized premiums and discounts, and previous OTTI recognized in earnings.

Expected maturities of PLRMBS will differ from contractual maturities because borrowers generally have the right to prepay the underlying obligations without prepayment fees.

At June 30, 2015, the amortized cost of the Bank’s PLRMBS classified as AFS included credit-related OTTI of $1,104. At December 31, 2014, the amortized cost of the Bank’s PLRMBS classified as AFS included credit-related OTTI of $1,173.

The following table summarizes the AFS securities with unrealized losses as of June 30, 2015, and December 31, 2014. 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 total gross unrealized losses in the table above. The unrealized losses in the following table also include non-credit-related OTTI losses recognized in AOCI. For OTTI analysis of AFS securities, see Note 6 – Other-Than-Temporary Impairment Analysis.

Total	$	474	$	15	$	2,298	$	179	$	2,772	$	194

As indicated in the tables above, as of June 30, 2015, the Bank’s investments classified as AFS had unrealized losses related to PLRMBS, which were primarily due to illiquidity in the PLRMBS market, uncertainty about the future condition of the housing and mortgage markets and the economy, and market expectations of the credit performance of loan collateral underlying these securities, which caused these assets to be valued at discounts to their acquisition cost.

Interest Rate Payment Terms. Interest rate payment terms for AFS securities at June 30, 2015, and December 31, 2014, are shown in the following table:

	June 30, 2015		December 31, 2014
Amortized cost of AFS PLRMBS:
Collateralized mortgage obligations:
Fixed rate	$	1,761	$	1,917
Adjustable rate	4,094		4,366
Total	$	5,855	$	6,283

Certain MBS classified as fixed rate collateralized mortgage obligations have an initial fixed interest rate that subsequently converts to an adjustable interest rate on a specified date as follows:

	June 30, 2015		December 31, 2014
Collateralized mortgage obligations:
Converts in 1 year or less	$	56	$	71
Converts after 1 year through 5 years	215		226
Total	$	271	$	297

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivatives and Hedging Activities

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 and the issuance of consolidated obligation bonds to create variable rate structures. The interest rate exchange agreements are generally executed at 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 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 derivative 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 that may be executed with members (with the Bank serving as an intermediary) or 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, (ii) an economic hedge of a specific asset or liability, or (iii) an intermediary transaction for members.

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 indexed to LIBOR.

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 all relationships between derivative hedging instruments and hedged items, its risk management objectives and strategies for undertaking various hedge transactions, and its method of assessing effectiveness. This process includes linking all derivatives that are designated as fair value or cash flow hedges to: (i) assets and liabilities on the balance sheet, (ii) firm commitments, or (iii) forecasted transactions. The Bank also formally assesses (both at the hedge’s inception and on an ongoing basis) whether the derivatives that are used in hedging transactions have been effective in offsetting changes in the fair value or cash flows of hedged items attributable to the hedged risk and whether those derivatives may be expected to remain effective 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 or cash flows 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.

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 derivatives receives 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 offsetting derivatives with other counterparties was $160 at June 30, 2015. The Bank had no interest rate exchange agreements associated with derivatives with members or offsetting derivatives with other counterparties at December 31, 2014.

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 array 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 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 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.

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 mortgages with lower-yielding assets and the Bank’s higher funding costs are not reduced accordingly.

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.

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 generally do not meet the requirements for fair value hedge accounting treatment.

The Bank did not have any consolidated obligations denominated in currencies other than U.S. dollars outstanding during the six months ended June 30, 2015, or the year ended December 31, 2014.

Credit Risk – The Bank is subject to credit risk as a result of the risk of potential nonperformance by counterparties to the derivative 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 and credit guidelines and Finance Agency regulations. The Bank also requires collateral agreements with collateral delivery thresholds on all uncleared derivatives. In addition, collateral related to derivative transactions with member institutions includes collateral pledged to the Bank, as evidenced by the Advances and Security Agreement, which may be held by the member institution for the benefit of the Bank.

For cleared derivatives, the clearinghouse is the Bank’s counterparty. The requirement that the Bank post initial and variation margin through the 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 and variation margin is posted daily for changes in the value of cleared derivatives through a clearing agent. 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 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 Bank’s agreements for uncleared derivative transactions contain provisions that link the Bank’s credit rating from Moody’s and Standard & Poor’s to various rights and obligations. Certain of these derivative agreements provide that, if the Bank’s long-term debt rating falls below A3/A- (and in one agreement, below A2/A), 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. In addition, under some of its agreements for uncleared derivative transactions, the amount of collateral that the Bank is required to deliver to a counterparty depends on the Bank’s credit rating. The aggregate fair value of all uncleared derivative instruments with credit-risk-related contingent features that were in a net derivative liability position (before cash collateral and related accrued interest) at June 30, 2015, was $42, for which the Bank had posted collateral with a fair value of $36 in the ordinary course of business. If the Bank’s credit rating at June 30, 2015, had been lowered from its current rating to the next lower rating, that would have triggered additional collateral to be delivered, and the Bank would have been required to deliver up to a total of $2 of additional collateral (at fair value) to its derivative counterparties at June 30, 2015.

The following table summarizes the fair value of derivative instruments including the effect of netting adjustments and cash collateral as of June 30, 2015, and December 31, 2014. For purposes of this disclosure, the derivative values include the fair value of derivatives and related accrued interest.

Consolidated Obligations

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 Statements and Supplementary Data – Note 20 – Commitments and Contingencies” in the Bank’s 2014 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 June 30, 2015, and December 31, 2014.

The Bank’s participation in consolidated obligation bonds outstanding includes callable bonds of $11,640 at June 30, 2015, and $14,158 at December 31, 2014. 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 $7,400 at June 30, 2015, and $9,573 at December 31, 2014. 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 June 30, 2015, and December 31, 2014, was as follows:  

	June 30, 2015		December 31, 2014

The Bank did not have any bonds 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 June 30, 2015, or December 31, 2014. The Bank has generally elected to account for bonds with embedded features under the fair value option, and these bonds are carried at fair value on the Statements of Condition.

Advances

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 0.16% to 8.57% at June 30, 2015, and 0.14% to 8.57% at December 31, 2014, 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 $4,782 at June 30, 2015, and $4,915 at December 31, 2014. Some advances may be repaid on pertinent call dates without prepayment fees (callable advances). The Bank had callable advances outstanding totaling $10,323 at June 30, 2015, and $328 at December 31, 2014.

The Bank’s advances at June 30, 2015, and December 31, 2014, included $140 and $140, respectively, of putable advances. 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.

The following table summarizes advances at June 30, 2015, and December 31, 2014, 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.

(1) Interest income amounts exclude the interest effect of interest rate exchange agreements with derivative counterparties; as a result, the total interest income amounts will not agree to the Statements of Income. The amount of interest income from advances can vary depending on the amount outstanding, terms to maturity, interest rates, and repricing characteristics.

(2) Nonmember institution.

The Bank held a security interest in collateral from each of the top five advances borrowers and their affiliates sufficient to support their respective advances outstanding, and the Bank does not expect to incur any credit losses on these advances.

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

Interest Rate Payment Terms. Interest rate payment terms for advances at June 30, 2015, and December 31, 2014, are detailed below:

	June 30, 2015		December 31, 2014
Par value of advances:
Fixed rate:
Due within 1 year	$	19,081	$	15,422
Due after 1 year	10,547		12,330
Total fixed rate	29,628		27,752
Adjustable rate:
Due within 1 year	5,979		5,906
Due after 1 year	14,454		5,172
Total adjustable rate	20,433		11,078
Total par value	$	50,061	$	38,830

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 June 30, 2015, or December 31, 2014. 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, as follows:

	Three Months Ended						Six Months Ended
	June 30, 2015			June 30, 2014			June 30, 2015			June 30, 2014

(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 June 30, 2015, the amortized cost of the Bank’s MBS classified as HTM included premiums of $46, discounts of $50, and credit-related OTTI of $7. At December 31, 2014, the amortized cost of the Bank’s MBS classified as HTM included premiums of $51, discounts of $55, and credit-related OTTI of $7.

The following tables summarize the HTM securities with unrealized losses as of June 30, 2015, and December 31, 2014. 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. For OTTI analysis of HTM securities, see Note 6 – Other-Than-Temporary Impairment Analysis.

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, uncertainty about the future condition of the housing and mortgage markets and the economy, and market expectations of the credit performance of the loan collateral underlying these securities, which caused these assets to be valued at discounts to their acquisition 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 June 30, 2015, and December 31, 2014, 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.

Other than Temporary Impairment Losses, Investments [Abstract]

Other-than-Temporary Impairment Analysis

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 meet neither 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 2.0% to an increase of 8.0% over the 12-month period beginning April 1, 2015. For the vast majority of markets, the projected short-term housing price changes range from an increase of 2.0% to an increase of 5.0%. 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 June 30, 2015 (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 in the second quarter of 2015, and the related current credit enhancement for the Bank.

June 30, 2015
	Significant Inputs for Other-Than-Temporarily Impaired PLRMBS			Current
	Prepayment Rates	Default Rates	Loss Severities	Credit Enhancement
Year of Securitization	Weighted Average %	Weighted Average %	Weighted Average %	Weighted Average %
Prime
2006	13.8	19.4	34.1	—
Total Prime	13.8	19.4	34.1	—

Total Alt-A, other	11.5	23.9	36.9	13.4
Total	11.5	23.9	36.9	13.4

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 (Prime; Alt-A, option ARM; and Alt-A, other) is based on the model used to run the estimated cash flows for the CUSIP, which may not necessarily be the same as the classification at the time of origination.

The following table presents the credit-related OTTI, which is recognized in earnings, for the three and six months ended June 30, 2015 and 2014.

	Three Months Ended June 30,						Six Months Ended June 30,

Balance, end of the period	$	1,284		$	1,347		$	1,284		$	1,347

(1) For the three months ended June 30, 2015 and 2014, “securities for which OTTI was previously recognized” represents all securities that were also other-than-temporarily impaired prior to April 1, 2015 and 2014, respectively. For the six months ended June 30, 2015 and 2014, “securities for which OTTI

was previously recognized” represents all securities that were also other-than-temporarily impaired prior to January 1, 2015 and 2014, respectively

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 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, 2015. 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 six months ended June 30, 2014.

Total	$	7,447	$	6,283	$	6,371	$	132	$	128	$	108	$	127

For the Bank’s PLRMBS that were not other-than-temporarily impaired as of June 30, 2015, the Bank has experienced net unrealized losses primarily because of illiquidity in the PLRMBS market, uncertainty about the future condition of the housing and mortgage markets and the economy, and market expectations of the credit performance of loan collateral underlying these securities, which caused these assets to be valued at discounts to their acquisition 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 June 30, 2015, 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 June 30, 2015, 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.

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 June 30, 2015, all of the gross unrealized losses on its agency MBS are temporary.

Capital [Abstract]

Capital

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.

As of June 30, 2015, and December 31, 2014, the Bank was in compliance with these capital rules and requirements as shown in the following table.  

	June 30, 2015						December 31, 2014
	Required			Actual			Required			Actual
Risk-based capital	$	2,923		$	5,546		$	3,231		$	6,356
Total regulatory capital	$	3,438		$	5,546		$	3,032		$	6,356
Total regulatory capital ratio	4.00		%	6.45		%	4.00		%	8.38		%
Leverage capital	$	4,298		$	8,318		$	3,790		$	9,534
Leverage ratio	5.00		%	9.68		%	5.00		%	12.58		%

Effective August 3, 2015, the Bank reduced its activity-based stock requirements within the ranges authorized by the Bank’s capital plan. The activity-based stock requirement for advances was reduced from 3.0% to 2.7%, and the activity-based stock requirement for mortgage loans purchased from the member and held by the Bank was reduced from 3.0% to 0.0%.

Mandatorily Redeemable Capital Stock. The Bank had mandatorily redeemable capital stock totaling $142 outstanding to 10 institutions at June 30, 2015, and $719 outstanding to 32 institutions at December 31, 2014. The change in mandatorily redeemable capital stock for the three and six months ended June 30, 2015 and 2014, was as follows:

	Three Months Ended						Six Months Ended
	June 30, 2015			June 30, 2014			June 30, 2015			June 30, 2014

Balance at the end of the period	$	142		$	1,176		$	142		$	1,176

Cash dividends on mandatorily redeemable capital stock were recorded as interest expense in the amount of $38 and $53 for the three and six months ended June 30, 2015, respectively, and in the amount of $34 and $73 for the three and six months ended June 30, 2014, respectively.

The Bank’s mandatorily redeemable capital stock is discussed more fully in “Item 8. Financial Statements and Supplementary Data – Note 15 – Capital” in the Bank’s 2014 Form 10-K.

The following table presents mandatorily redeemable capital stock amounts by contractual redemption period at June 30, 2015, and December 31, 2014.

Contractual Redemption Period	June 30, 2015		December 31, 2014

Excess Stock Repurchase, Retained Earnings, and Dividend Framework. The Bank’s Excess Stock Repurchase, Retained Earnings, and Dividend 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.

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 201% as of June 30, 2015.

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.

Retained Earnings – The Bank’s Excess Stock Repurchase, Retained Earnings, and Dividend Framework establishes amounts to be retained in restricted retained earnings, which are not made available in the current dividend period.

The following table summarizes the activity related to restricted retained earnings for the three and six months ended June 30, 2015 and 2014:

For more information on these three categories of restricted retained earnings and the Bank’s Excess Stock Repurchase, Retained Earnings, and Dividend Framework, see “Item 8. Financial Statements and Supplementary Data – Note 15 – Capital” in the Bank’s 2014 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 June 30, 2015, the Bank’s excess capital stock totaled $365, or 0.42% of total assets.

In the second quarter of 2015, the Bank paid dividends on the capital stock outstanding during the first quarter of 2015 at an annualized rate of 22.65%, totaling $220, including $182 in dividends on capital stock and $38 in dividends on mandatorily redeemable capital stock. The dividends included a special dividend in the amount of $145, including $120 in dividends on capital stock and $25 in dividends on mandatorily redeemable capital stock. In the second quarter of 2014, the Bank paid dividends on the capital stock outstanding during the first quarter of 2014 at an annualized rate of 6.80%, totaling $93, including $59 in dividends on capital stock and $34 in dividends on mandatorily redeemable capital stock.

In the first six months of 2015, the Bank paid dividends at an annualized rate of 14.58%, totaling $294, of which $145 was related to the special dividend. The total dividends paid included $241 in dividends on capital stock and $53 in dividends on mandatorily redeemable capital stock. In the first six months of 2014, the Bank paid dividends at an annualized rate of 6.73%, totaling $190, including $117 in dividends on capital stock and $73 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 July 28, 2015, the Bank’s Board of Directors declared a cash dividend on the capital stock outstanding during the second quarter of 2015 at an annualized rate of 10.01%, totaling $78, including $72 in dividends on capital stock and $6 in dividends on mandatorily redeemable capital stock. The Bank recorded the dividend on July 28, 2015. The Bank expects to pay the dividend on or about August 13, 2015. Dividends on mandatorily redeemable capital stock will be recognized as interest expense in the third quarter of 2015.

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 some or all of a shareholder’s excess capital stock at the shareholder’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 $750 and $847 in excess capital stock in the first and second quarters of 2015, respectively, and $750 in excess capital stock in each of the first and second quarters of 2014.

During the second quarter of 2015 and 2014, the Bank redeemed $28 and $6, respectively, 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 May 29, 2015, the Bank's Excess Stock Repurchase, Retained Earnings, and Dividend Framework (Framework) was revised to reinstate the Bank’s practice of repurchasing the surplus capital stock of all members and the excess capital stock of all nonmember shareholders on a regular quarterly schedule, at the Bank’s discretion and subject to certain statutory and regulatory requirements and to the Bank’s Risk Management Policy and capital plan limitations. Surplus capital stock is defined as any stock holdings in excess of 115% of a member’s minimum stock requirement, and excess capital stock is defined as any stock holdings in excess of a shareholder’s minimum stock requirement. In accordance with the revised Framework, each quarter, Bank management will evaluate and determine the amount of capital stock to be repurchased in that quarter, if any, giving consideration to certain capital metrics and capital management objectives and strategies, and subject to the requirements and limitations mentioned above. In addition, at the Bank’s discretion, some or all of the excess stock held by a shareholder may be repurchased upon request of the shareholder, subject to the requirements and limitations mentioned above. At least 15 calendar days before any repurchase, the Bank will notify shareholders of its intention to repurchase capital stock and of the scheduled repurchase date. On the scheduled repurchase date, the Bank will calculate the amount of stock to be repurchased to ensure that each member and nonmember shareholder will continue to meet its minimum stock requirement after the repurchase.

On July 29, 2015, the Bank announced that it plans to repurchase the surplus capital stock of all members and the excess capital stock of all nonmember shareholders on August 14, 2015.

Excess capital stock totaled $365 as of June 30, 2015, and $1,118 as of December 31, 2014.

For more information on excess capital stock, see “Item 8. Financial Statements and Supplementary Data – Note 15 – Capital” in the Bank’s 2014 Form 10-K.

Recently Issued and Adopted Accounting Guidance

Jun. 30, 2015

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]

Recently Issued and Adopted Accounting Guidance

Recently Issued and Adopted Accounting Guidance

Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement. On April 15, 2015, the Financial Accounting Standards Board (FASB) issued amendments to clarify a customer’s accounting for fees paid in a cloud computing arrangement. The amendments provide guidance to customers on determining whether a cloud computing arrangement includes a software license that should be accounted for as internal-use software. If the arrangement does not contain a software license, it would be accounted for as a service contract. This guidance becomes effective for the Bank for the interim and annual periods beginning after December 15, 2015, and early adoption is permitted. The Bank can elect to adopt the amendments either (1) prospectively to all arrangements entered into or materially modified after the effective date or (2) retrospectively. The Bankis in the process of evaluating this guidance and its effect on the Bank’s financial condition, results of operations, and cash flows.

Simplifying the Presentation of Debt Issuance Costs. On April 7, 2015, the FASB issued guidance to simplify the presentation of debt issuance costs. This guidance requires that debt issuance costs related to a recognized debt liability be presented on the statement of condition as a direct deduction from the carrying amount of that debt liability, consistent with the presentation of debt discounts. The adoption of this guidance will result in a reclassification of debt issuance costs from other assets to consolidated obligations on the Bank’s Statements of Condition. This guidance becomes effective for the Bank for the interim and annual periods beginning after December 15, 2015, and early adoption is permitted for financial statements that have not been previously issued. The guidance is required to be applied on a retrospective basis to each individual period presented on the statement of condition. The Bank is in the process of evaluating this guidance and its effect on the Bank’s financial condition, results of operations, and cash flows.

Amendments to the Consolidation Guidance. On February 18, 2015, the FASB issued guidance intended to enhance consolidation guidance for legal entities such as limited partnerships, limited liability corporations, and securitization structures (collateralized debt obligations, collateralized loan obligations, and mortgage-backed security transactions). The new guidance primarily focuses on the following:

• Placing more emphasis on risk of loss when determining a controlling financial interest. A reporting organization may no longer have to consolidate a legal entity in certain circumstances based solely on its fee arrangement, when certain criteria are met.

• Reducing the frequency of the application of related-party guidance when determining a controlling financial interest in a VIE.

• Changing consolidation conclusions for public and private companies in several industries that typically make use of limited partnerships or VIEs.

This guidance becomes effective for the Bank for interim and annual periods beginning after December 15, 2015, and early adoption is permitted, including adoption in an interim period. This guidance is not expected to affect the Bank’s financial condition, results of operations, and cash flows.

Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern.On August 27, 2014, the FASB issued guidance about management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosures. This guidance requires management to perform interim and annual assessments of an entity’s ability to continue as a going concern within one year after the date the financial statements are issued or within one year after the financial statements are available to be issued, when applicable. Substantial doubt exists if it is probable that the entity will be unable to meet its obligations for the assessed period. This guidance becomes effective for the Bank for the interim and annual periods ending after December 15, 2016, and early application is permitted. This guidance is not expected to affect the Bank’s financial condition, results of operations, and cash flows.

Classification of Certain Government-Guaranteed Mortgage Loans upon Foreclosure.On August 8, 2014, the FASB issued amended guidance relating to the classification and measurement of certain government-guaranteed mortgage loans upon foreclosure. The amendments in this guidance require that a mortgage loan be derecognized and that a separate other receivable be recognized upon foreclosure if certain conditions are met. This guidance became effective for the Bank for the interim and annual periods beginning on January 1, 2015, and was adopted prospectively. The adoption of this guidance did not affect the Bank’s financial condition, results of operations, or cash flows.

Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures.On June 12, 2014, the FASB issued amended guidance for repurchase-to-maturity transactions and repurchase agreements executed as repurchase financings. Specifically, this guidance requires entities to account for (1) repurchase-to-maturity transactions as secured borrowings rather than as sales with forward repurchase agreements; and (2) repurchase agreements executed contemporaneously with the initial transfer of the underlying financial asset with the same counterparty as separate transactions only. In addition, this guidance requires a transferor to disclose additional information about certain transactions, including those in which it retains substantially all of the exposure to the economic returns of the underlying transferred asset over the transaction’s term. This guidance became effective for the Bank for the interim and annual periods beginning on January 1, 2015. The changes in accounting for transactions outstanding on the effective date are required to be presented on a cumulative-effect basis. The adoption of this guidance did not affect the Bank’s financial condition, results of operations, 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 entities to use in accounting for 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, or lease contracts.

This guidance becomes effective for the interim and annual reporting periods beginning after December 15, 2016, and early application is not permitted. The guidance provides the entities with the option of using the following two methods upon adoption: a full retrospective method, applied retrospectively to each prior reporting period presented; or a transition method, with the cumulative effect of retrospectively applying this guidance recognized at the date of initial application. The Bank is in the process of evaluating this guidance and its effect on the Bank’s financial condition, results of operations, and cash flows, but it is not expected to be material.

Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure. On January 17, 2014, theFASB issued guidance clarifying when consumer mortgage loans collateralized by real estate should be reclassified to REO. Specifically, these collateralized mortgage loans should be reclassified to REO when either the creditor obtains legal title to the residential real estate property upon completion of a foreclosure or the borrower conveys all interest in the residential real estate property to the creditor to satisfy the loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. The guidance became effective for interim and annual periods beginning on January 1, 2015, and was adopted prospectively. The adoption of this guidance did not affect the Bank’s financial condition, results of operations, or cash flows.

Regulatory Guidance

Framework for Adversely Classifying Loans, Other Real Estate Owned, and Other Assets and Listing Assets for Special Mention.On April 9, 2012, the Finance Agency issued Advisory Bulletin 2012-02, Framework for Adversely Classifying Loans, Other Real Estate Owned, and Other Assets and Listing Assets for Special Mention (AB 2012-02). The guidance establishes a standard and uniform methodology for classifying loans, other real estate owned, and certain other assets (excluding investment securities) and prescribes the timing of asset charge-offs based on these classifications. The guidance is generally consistent with the Uniform Retail Credit Classification and Account Management Policy issued by the federal banking regulators in June 2000. The Bank implemented the asset classification provisions as of January 1, 2014, and this adoption did not have any impact on the Bank’s financial condition, results of operations, or cash flows. The charge-off provisions were implemented on January 1, 2015, and resulted in a $1 charge-off to the Bank’s allowance for credit losses on the mortgage loan portfolio for the six months ended June 30, 2015. The adoption of these charge-off provisions did not have a material effect on the Bank’s financial condition, results of operations, or cash flows.
