Federal Home Loan Bank of San Francisco
Notes to Financial Statements
(Unaudited)


(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, 2016. 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, 2015 (2015 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; 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 March 31, 2016, 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 maximum loss exposure for these VIEs is limited to the Bank’s investment in the VIE.

Interest-bearing Deposits. This investment provides short-term liquidity and is carried at cost. Interest-bearing deposits include interest-bearing deposits in banks not meeting the definition of a security. Interest income on interest-bearing deposits is accrued as earned and recorded in interest income on Statements of Income.

Reclassifications of Prior Period Amounts Related to Concessions on Consolidated Obligations . On January 1, 2016, the Bank retrospectively adopted the guidance, Simplifying the Presentation of Debt Issuance Costs, issued by the Financial Accounting Standards Board (FASB) on April 7, 2015. The Bank pays concessions to dealers in connection with the issuance of certain consolidated obligations for which the Bank is the primary obligor. The amount of concessions is allocated to the Bank by the Office of Finance based on the percentage of the debt issued for which the Bank is the primary obligor. Concessions paid on consolidated obligations designated under the fair value option are expensed as incurred in non-interest expense. Concessions paid on consolidated obligations not designated under the fair value option are deferred and amortized to expense using the level-yield method over the remaining contractual life or on a retrospective basis over the estimated life of the consolidated obligations. The amortization of those concessions is included in consolidated obligation interest expense. Unamortized concessions were $8 and $9 at March 31, 2016, and December 31, 2015, respectively. Prior to the adoption of the guidance unamortized concessions were included in “Other assets.” Upon adoption of the guidance, unamortized concessions were reclassified as a reduction in the balance of the corresponding consolidated obligations, consistent with the presentation of discounts on consolidated obligations.

As a result of adopting this guidance, $9 of unamortized concessions included in other assets at December 31, 2015, was reclassified as a reduction in the balance of the corresponding consolidated obligations to conform to the financial statement presentation on the Bank’s Statements of Condition as of March 31, 2016. The reclassification resulted in a decrease of $1 in consolidated obligation discount notes and of $8 in consolidated obligation bonds at December 31, 2015. Accordingly, the Bank’s total assets and total liabilities each decreased by $9 at December 31, 2015. The adoption of this guidance did not have any effect on the Bank’s results of operations and cash flows.

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 2015 Form 10-K. Other changes to these policies as of March 31, 2016, are discussed in Note 2 – Recently Issued and Adopted Accounting Guidance.

Note 2 — Recently Issued and Adopted Accounting Guidance

Contingent Put and Call Options in Debt Instruments. On March 14, 2016, the FASB issued amendments to clarify the requirements for assessing whether contingent call (put) options that can accelerate the payment of principal on debt instruments are clearly and closely related to their debt hosts. The guidance requires entities to apply only the four-step decision sequence when assessing whether the economic characteristics and risks of call (put) options are clearly and closely related to the economic characteristics and risks of their debt hosts. Consequently, when a call (put) option is contingently exercisable, an entity does not have to assess whether the event that triggers the ability to exercise a call (put) option is related to interest rates or credit risks. This guidance becomes effective for the Bank for the interim and annual periods beginning on January 1, 2017, and early adoption is permitted. The guidance should be applied on a modified retrospective basis to existing debt instruments as of the beginning of the period for which the amendments are effective. 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 has not yet been determined.

Effect of Derivative Contract Novations on Existing Hedge Accounting Relationships. On March 10, 2016, the FASB issued amendments to clarify that a change in the counterparty to a derivative instrument that has been designated as the hedging instrument under GAAP does not, in and of itself, require dedesignation of that hedging relationship provided that all other hedge accounting criteria continue to be met. This guidance becomes effective for the Bank for the interim and annual periods beginning on January 1, 2017, and early adoption is permitted. The amendments provide entities with the option to apply the guidance using either a prospective approach or a

10

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



modified retrospective approach, retrospectively applied to all derivative instruments that meet the specific conditions. The Bank elected to early adopt the guidance prospectively on January 1, 2016. The adoption of this guidance had no effect on the Bank’s financial condition, results of operations, and cash flows.

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

The guidance becomes effective for the Bank for the interim and annual periods beginning on January 1, 2019, and early application is permitted. The guidance requires lessors and lessees to recognize and measure leases at the beginning of the earliest period presented in the financial statements using a modified retrospective approach. The Bank is in the process of evaluating this guidance, and its effect on the Bank’s financial condition, results of operations, and cash flows has not yet been determined.

Recognition and Measurement of Financial Assets and Financial Liabilities. On January 5, 2016, the FASB issued amended guidance on certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. This guidance includes, but is not limited to, the following:
•
Requires equity investments (with certain exceptions) to be measured at fair value with changes in fair value recognized in net income;
•
Requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments;
•
Requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset on the balance sheet or in the accompanying notes to the financial statements;
•
Eliminates the requirement for public entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet.

The guidance becomes effective for the Bank for the interim and annual periods beginning on January 1, 2018, and early adoption is only permitted for certain provisions. The amendments, in general, should be applied by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the period of adoption. 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 has not yet been determined.

Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement. On April 15, 2015, the 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 became effective for the Bank for the interim and annual periods beginning January 1, 2016, and was adopted prospectively. The adoption of this guidance did not have an impact on the Bank’s financial condition, results of operations, or 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 Statements of Condition as a direct deduction from the carrying amount of that debt

Notes to Financial Statements (continued)



liability, consistent with the presentation of debt discounts. The adoption of this guidance will result in a reclassification of unamortized debt issuance costs from other assets to consolidated obligations on the Bank’s Statements of Condition. This guidance became effective for the Bank for the interim and annual periods beginning January 1, 2016, and was adopted retrospectively. See Note 1 – Basis of Presentation for discussion of the impact of reclassifications of prior period amounts.

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

This guidance became effective for the Bank for interim and annual periods beginning January 1, 2016. The adoption of this guidance did not affect the Bank’s financial condition, results of operations, or 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 annual period ending after December 15, 2016, and for the annual and interim periods thereafter. Early application is permitted. This guidance is not expected to 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 recognizing revenue arising from contracts with customers and supersedes most current revenue recognition guidance. In addition, this guidance amends the existing requirements for the recognition of a gain or loss on the transfer of non-financial assets that are not in a contract with a customer. This guidance applies to all contracts with customers except those that are within the scope of certain other standards, such as financial instruments, certain guarantees, insurance contracts, and lease contracts.

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

On August 12, 2015, the FASB issued an amendment to defer the effective date of the guidance issued in May 2014 by one year. In 2016, the FASB has issued additional amendments to clarify certain aspects of the new revenue guidance. However, the amendments do not change the core principle in the new revenue standard. The guidance is effective for the Bank for interim and annual periods beginning after December 15, 2017. Early application is permitted only as of the interim and annual reporting periods beginning after December 15, 2016.

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 March 31, 2016, the amortized cost of the Bank’s PLRMBS classified as AFS included credit-related OTTI of $981. At December 31, 2015, the amortized cost of the Bank’s PLRMBS classified as AFS included credit-related OTTI of $1,023.

The following table summarizes the AFS securities with unrealized losses as of March 31, 2016, and December 31, 2015. 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.

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

16

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



Bank expects to recover the entire amortized cost basis of these securities because the Bank determined that the strength of the issuers’ guarantees through direct obligations or support from the U.S. government is sufficient to protect the Bank from losses. The unrealized losses associated with the PLRMBS were primarily due to illiquidity in the PLRMBS market and market expectations of the credit performance of loan collateral underlying these securities, which caused these assets to be valued at discounts to their amortized cost.

Redemption Terms. The amortized cost, carrying value, and estimated fair value of non-MBS securities by contractual maturity (based on contractual final principal payment) and of MBS as of March 31, 2016, and December 31, 2015, 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 do not meet either of these conditions (the most common situation), 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 1.0% to an increase of 8.0% over the 12-month period beginning January 1, 2016. For the vast majority of markets, the projected short-term housing price changes range from an increase of 3.0% 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 March 31, 2016 (securities for which the Bank determined that it does not expect to recover the entire amortized cost basis), the following table presents a summary of the significant inputs used in measuring the amount of credit loss recognized in earnings during the first quarter of 2016, and the related current credit enhancement for the Bank.

(1) Weighted average percentage is based on unpaid principal balance.

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 months ended March 31, 2016 and 2015.

Notes to Financial Statements (continued)



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 Bank elected to transfer any PLRMBS that incurred a credit-related OTTI charge during the applicable period from the Bank’s held-to-maturity portfolio to its available-for-sale portfolio at their fair values. The Bank recognized an OTTI credit loss on these held-to-maturity PLRMBS, which the Bank believes is evidence of a significant decline in the issuers’ creditworthiness. The decline in the issuers’ creditworthiness is the basis for the transfers to the available-for-sale portfolio. These transfers allow the Bank the option to sell these securities prior to maturity in view of changes in interest rates, changes in prepayment risk, or other factors, while recognizing the Bank’s intent to hold these securities for an indefinite period of time. The Bank does not intend to sell its other-than-temporarily impaired securities and it is not more likely than not that the Bank will be required to sell any security before its anticipated recovery of the remaining amortized cost basis.

The following table summarizes the PLRMBS transferred from the Bank’s HTM portfolio to its AFS portfolio during the three months ended March 31, 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 months ended March 31, 2016.
