[1]	(1) Prior to our adoption of Accounting Standards Update (ASU) 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (CECL) , on January 1, 2020, provision for credit losses from debt securities was not applicable and is therefore presented as $0 for both the second quarter and first half of 2019 . For more information, see Note 1 (Summary of Significant Accounting Policies) to Financial Statements in this Report.
[2]	(2) In second quarter 2020, insurance income was reclassified to other noninterest income, personnel-related expenses were combined into a single line item, and expenses for cloud computing services were reclassified from contract services expense (within other noninterest expense) to technology and equipment expense. Prior period balances have been revised to conform with the current period presentation.
[3]	(3) In second quarter 2020, diluted earnings per common share equaled earnings per common share because our securities convertible into common shares had an anti-dilutive effect.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 1: Summary of Significant Accounting Policies Wells Fargo & Company is a diversified financial services company. We provide banking, trust and investments, mortgage banking, investment banking, retail banking, brokerage, and consumer and commercial finance through banking locations, the internet and other distribution channels to consumers, businesses and institutions in all 50 states, the District of Columbia, and in foreign countries. When we refer to “Wells Fargo,” “the Company,” “we,” “our” or “us,” we mean Wells Fargo & Company and Subsidiaries (consolidated). Wells Fargo & Company (the Parent) is a financial holding company and a bank holding company. We also hold a majority interest in a real estate investment trust, which has publicly traded preferred stock outstanding. Our accounting and reporting policies conform with U.S. generally accepted accounting principles (GAAP) and practices in the financial services industry. For discussion of our significant accounting policies, see Note 1 (Summary of Significant Accounting Policies) in our Annual Report on Form 10-K for the year ended December 31, 2019 ( 2019 Form 10-K). To prepare the financial statements in conformity with GAAP, management must make estimates based on assumptions about future economic and market conditions (for example, unemployment, market liquidity, real estate prices, etc.) that affect the reported amounts of assets and liabilities at the date of the financial statements, income and expenses during the reporting period and the related disclosures. Although our estimates contemplate current conditions and how we expect them to change in the future, it is reasonably possible that actual conditions could be worse than anticipated in those estimates, which could materially affect our results of operations and financial condition. Management has made significant estimates in several areas, including: • allowance for credit losses (Note 6 (Loans and Related Allowance for Credit Losses); • valuations of residential mortgage servicing rights (MSRs) (Note 10 (Securitizations and Variable Interest Entities) and Note 11 (Mortgage Banking Activities)); • valuations of financial instruments (Note 15 (Derivatives) and Note 16 (Fair Values of Assets and Liabilities)); • liabilities for contingent litigation losses (Note 14 (Legal Actions)); and • income taxes. Actual results could differ from those estimates. These unaudited interim financial statements reflect all adjustments that are, in the opinion of management, necessary for a fair statement of the results for the periods presented. These adjustments are of a normal recurring nature, unless otherwise disclosed in this Form 10-Q. The results of operations in the interim financial statements do not necessarily indicate the results that may be expected for the full year. The interim financial information should be read in conjunction with our 2019 Form 10-K. Accounting Standards Adopted in 2020 In 2020 , we adopted the following new accounting guidance: • Accounting Standards Update (ASU or Update) 2020-04 – Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting • ASU 2019-04 – Codification Improvements to Topic 326, Financial Instruments – Credit Losses , Topic 815, Derivatives and Hedging , and Topic 825, Financial Instruments . This Update includes guidance on recoveries of financial assets, which is included in the discussion for ASU 2016-13 below. • ASU 2018-17 – Consolidation (Topic 810): Targeted Improvements to Related Party Guidance for Variable Interest Entities • ASU 2018-15 – Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (a consensus of the Financial Accounting Standards Board (FASB) Emerging Issues Task Force) • ASU 2018-13 – Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement. • ASU 2017-04 – Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment • ASU 2016-13 – Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments and related subsequent Updates ASU 2020-04 provides optional, temporary relief to ease the burden of accounting for reference rate reform activities that affect contractual modifications of floating rate financial instruments indexed to interbank offering rates (IBORs) and hedge accounting relationships. Modifications of qualifying contracts are accounted for as the continuation of an existing contract rather than as a new contract. Modifications of qualifying hedging relationships will not require discontinuation of the existing hedge accounting relationships. The application of the relief for qualifying existing hedging relationships may be made on a hedge-by-hedge basis and across multiple reporting periods. We adopted ASU 2020-04 on April 1, 2020, and the guidance will be followed until the Update terminates on December 31, 2022. This guidance is applied on a prospective basis. The Update did not have a material impact on our consolidated financial statements in second quarter 2020. ASU 2018-17 updates the guidance used by decision-makers of VIEs. Indirect interests held through related parties in common control arrangements will be considered on a proportional basis for determining whether fees paid to decision-makers and service providers are variable interests. This is consistent with how indirect interests held through related parties under common control are considered for determining whether a reporting entity must consolidate a VIE. The Update did not have a material impact on our consolidated financial statements. ASU 2018-15 clarifies the accounting for implementation costs related to a cloud computing arrangement that is a service contract and enhances disclosures around implementation costs for internal-use software and cloud computing arrangements. The guidance aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). It also requires the expense related to the capitalized implementation costs be presented in the same line item in the statement of income as the fees associated with the hosting element of the arrangement and capitalized implementation costs be presented in the balance sheet in the same line item that a prepayment for the fees of the associated hosting arrangement are presented. The Update did not have a material impact on our consolidated financial statements. ASU 2018-13 clarifies, eliminates and adds certain fair value measurement disclosure requirements for assets and liabilities, which affects our disclosures in Note 16 (Fair Values of Assets and Liabilities). Although the ASU became effective on January 1, 2020, it permitted early adoption of individual requirements without causing others to be early adopted and, as such, we partially adopted the Update during third quarter 2018 and the remainder of the requirements in first quarter 2020. The Update did not have a material impact on our consolidated financial statements. ASU 2017-04 simplifies the goodwill impairment test by eliminating the requirement to assign the fair value of a reporting unit to all of the assets and liabilities of that unit (including any unrecognized intangible assets) as if the reporting unit had been acquired in a business combination. The Update requires that a goodwill impairment loss is recognized if the fair value of the reporting unit is less than the carrying amount, including goodwill. The goodwill impairment loss is limited to the amount of goodwill allocated to the reporting unit. The guidance did not change the qualitative assessment of goodwill. This guidance is applied on a prospective basis, and accordingly, the Update did not have a material impact on our consolidated financial statements. ASU 2016-13 changes the accounting for the measurement of credit losses on loans and debt securities. For loans and held-to-maturity (HTM) debt securities, the Update requires a current expected credit loss (CECL) measurement to estimate the allowance for credit losses (ACL) for the remaining contractual term, adjusted for prepayments, of the financial asset (including off-balance sheet credit exposures) using historical experience, current conditions, and reasonable and supportable forecasts. Also, the Update eliminates the existing guidance for purchased credit-impaired (PCI) loans, but requires an allowance for purchased financial assets with more than an insignificant deterioration of credit since origination. In addition, the Update modifies the other-than-temporary impairment (OTTI) model for available-for-sale (AFS) debt securities to require an allowance for credit impairment instead of a direct write-down, which allows for reversal of credit impairments in future periods based on improvements in credit. Upon adoption, we recognized an overall decrease in our ACL of approximately $1.3 billion (pre-tax) as a cumulative effect adjustment from a change in accounting policies, which increased our retained earnings and regulatory capital amounts and ratios. Loans previously classified as PCI were automatically transitioned to purchased credit-deteriorated (PCD) classification. We recognized an ACL for these new PCD loans and made a corresponding adjustment to the loan balance, with no impact to net income or transition adjustment to retained earnings. For more information on the impact of CECL by type of financial asset, see Table 1.1 below. Table 1.1: ASU 2016-13 Adoption Impact to Allowance for Credit Losses (1) Dec 31, 2019 ASU 2016-13 Adoption Impact Jan 1, 2020 (in billions) Balance Outstanding ACL Balance Coverage ACL Balance Coverage Total commercial (2) $ 515.7 6.2 1.2 % $ (2.9 ) 3.4 0.7 % Real estate 1-4 family mortgage (3) 323.4 0.9 0.3 — 0.9 0.3 Credit card (4) 41.0 2.3 5.5 0.7 2.9 7.1 Automobile (4) 47.9 0.5 1.0 0.3 0.7 1.5 Other revolving credit and installment (4) 34.3 0.6 1.6 0.6 1.2 3.5 Total consumer 446.5 4.2 0.9 1.5 5.7 1.3 Total loans 962.3 10.5 1.1 (1.3 ) 9.1 0.9 Available-for-sale and held-to-maturity debt securities and other assets (5) 420.0 0.1 NM — 0.1 NM Total $ 1,382.3 10.6 NM $ (1.3 ) 9.3 NM NM – Not meaningful (1) Amounts presented in this table may not equal the sum of its components due to rounding. (2) Decrease reflecting shorter contractual maturities given limitation to contractual terms. (3) Impact reflects an increase due to longer contractual terms, offset by expectation of recoveries in collateral value on mortgage loans previously written down significantly below current recovery value. (4) Increase due to longer contractual terms or indeterminate maturities. (5) Excludes other financial assets in the scope of CECL that do not have an allowance for credit losses based on the nature of the asset. The adoption of ASU 2016-13 did not result in a change to accounting policies, except as noted herein. Our accounting policy for the ACL was updated and is now inclusive of loans, debt securities and other financing receivables. Other than the ACL and the elimination of PCI loans, there were no changes to accounting policies for loans as described in the 2019 Form 10-K. For debt securities, other than the policies with respect to the ACL, all of the current accounting policies, including those that changed as a result of CECL adoption, are included below under Debt Securities. Debt Securities Our investments in debt securities that are not held for trading purposes are classified as either debt securities available-for-sale (AFS) or held-to-maturity (HTM). Investments in debt securities for which the Company does not have the positive intent and ability to hold to maturity are classified as AFS. AFS debt securities are measured at fair value, with unrealized gains and losses reported in cumulative other comprehensive income (OCI), net of the allowance for credit losses and applicable income taxes. Investments in debt securities for which the Company has the positive intent and ability to hold to maturity are classified as HTM. HTM debt securities are measured at amortized cost, net of allowance for credit losses. INTEREST INCOME AND GAIN/LOSS RECOGNITION Unamortized premiums and discounts are recognized in interest income over the contractual life of the security using the effective interest method, except for purchased callable debt securities carried at a premium. For purchased callable debt securities carried at a premium, the premium is amortized into interest income to the earliest call date using the effective interest method. As principal repayments are received on securities (e.g., mortgage-backed securities (MBS)), a proportionate amount of the related premium or discount is recognized in income so that the effective interest rate on the remaining portion of the security continues unchanged. We recognize realized gains and losses on the sale of debt securities in net gains (losses) on debt securities within noninterest income using the specific identification method. IMPAIRMENT AND CREDIT LOSSES Unrealized losses of AFS debt securities are driven by a number of factors, including changes in interest rates and credit spreads which impact most types of debt securities with additional considerations for certain types of debt securities: • Debt securities of U.S. Treasury and federal agencies, including federal agency MBS, are not impacted by credit movements given the explicit or implicit guarantees provided by the U.S. government. • Debt securities of U.S. states and political subdivisions are most impacted by changes in the relationship between municipal and term funding credit curves rather than by changes in the credit quality of the underlying securities. • Structured securities, such as MBS and collateralized loan obligations (CLO), are also impacted by changes in projected collateral losses of assets underlying the security. For debt securities where fair value is less than amortized cost basis, we recognize impairment in earnings if we have the intent to sell the security or if it is more likely than not that we will be required to sell the security before recovery of its amortized cost basis. Impairment is recognized equal to the entire difference between the amortized cost basis and the fair value of the security and is classified as net gains (losses) from debt securities within noninterest income. Following the recognition of impairment, the security’s new amortized cost basis is the previous basis less impairment. For debt securities where fair value is less than amortized cost basis where we did not recognize impairment in earnings, we set up an allowance for credit losses as of the balance sheet date. See “Allowance for Credit Losses” section in this Note. TRANSFERS BETWEEN CATEGORIES OF DEBT SECURITIES AFS debt securities transferred to the HTM classification are recorded at fair value and the unrealized gains or losses resulting from the transfer of these securities continue to be reported in cumulative OCI. The cumulative OCI balance is amortized into earnings over the same period as the unamortized premiums and discounts using the effective interest method. Any allowance for credit losses previously recorded under the AFS model on securities transferred to HTM is reversed and an allowance for credit losses is subsequently recorded under the HTM debt security model. NONACCRUAL AND PAST DUE, AND CHARGE-OFF POLICIES We generally place debt securities on nonaccrual status using factors similar to those described for loans. When we place a debt security on nonaccrual status, we reverse the accrued unpaid interest receivable against interest income and suspend the amortization of premiums and accretion of discounts. If the ultimate collectability of the principal is in doubt on a nonaccrual debt security, any cash collected is first applied to reduce the security’s amortized cost basis to zero, followed by recovery of amounts previously charged off, and subsequently to interest income. Generally, we return a debt security to accrual status when all delinquent interest and principal become current under the contractual terms of the security and collectability of remaining principal and interest is no longer doubtful. Our debt securities are considered past due when contractually required principal or interest payments have not been made on the due dates. Our charge-off policy for debt securities are similar to those described for loans. Subsequent to charge-off, the debt security will be designated as nonaccrual and follow the process described above for any cash received. Allowance for Credit Losses The ACL is management’s estimate of the current expected credit losses in the loan portfolio and unfunded credit commitments, at the balance sheet date, excluding loans and unfunded credit commitments carried at fair value or held for sale. Additionally, we maintain an ACL on AFS and HTM debt securities, other financing receivables measured at amortized cost, and other off-balance sheet credit exposures. While we attribute portions of the allowance to specific financial asset classes (loan and debt security portfolios), loan portfolio segments (commercial and consumer) or major security type, the entire ACL is available to absorb credit losses of the Company. Our ACL process involves procedures to appropriately consider the unique risk characteristics of our financial asset classes, portfolio segments, and major security types. For each loan portfolio segment and each major HTM debt security type, losses are estimated collectively for groups of loans or securities with similar risk characteristics. For loans and securities that do not share similar risk characteristics with other financial assets, the losses are estimated individually, which primarily includes our impaired large commercial loans and non-accruing HTM debt securities. For AFS debt securities, losses are estimated at the tax-lot level. Our ACL amounts are influenced by a variety of factors, including changes in loan and debt security volumes, portfolio credit quality, and general economic conditions. General economic conditions are forecasted using economic variables which will create volatility as those variables change over time. See Table 1.2 for key economic variables used for our loan portfolios. Table 1.2: Key Economic Variables Loan Portfolio Key economic variables Total commercial • Gross domestic product • Commercial real estate asset prices, where applicable • Unemployment rate • Corporate investment-grade bond spreads Real estate 1-4 family mortgage • Home price index • Unemployment rate Other consumer (including credit card, automobile, and other revolving credit and installment) • Unemployment rate Our approach for estimating expected life-time credit losses for loans and debt securities includes the following key components: • An initial loss forecast period of one year for all portfolio segments and classes of financing receivables and off-balance-sheet credit exposures. This period reflects management’s expectation of losses based on forward-looking economic scenarios over that time. • A historical loss forecast period covering the remaining contractual term, adjusted for expected prepayments and certain expected extensions, renewals, or modifications, by portfolio segment and class of financing receivables based on the changes in key historical economic variables during representative historical expansionary and recessionary periods. • A reversion period of up to two years to connect the losses estimated for our initial loss forecast period to the period of our historical loss forecast based on economic conditions at the measurement date. Our reversion methodology considers the type of portfolio, point in the credit cycle, expected length of recessions and recoveries, as well as other relevant factors. • Utilization of discounted cash flow (DCF) methods to measure credit impairment for loans modified in a troubled debt restructuring, unless they are collateral dependent and measured at the fair value of the collateral. The DCF methods obtain estimated life-time credit losses using the initial and historical mean loss forecast periods described above. • For AFS debt securities and certain beneficial interests classified as HTM, we utilize the DCF methods to measure the ACL, which incorporate expected credit losses using the conceptual components described above. The ACL on AFS debt securities is subject to a limitation based on the fair value of the debt securities (fair value floor). The ACL for financial assets held at amortized cost and AFS debt securities will be reversible with immediate recognition of recovery in earnings if credit improves. The ACL for financial assets held at amortized cost is a valuation account that is deducted from, or added to, the amortized cost basis of the financial assets to present the net amount expected to be collected, which can include a negative allowance limited to the cumulative amounts previously charged off. For financial assets with an ACL estimated using DCF methods, changes in the ACL due to the passage of time are recorded in interest income. The ACL for AFS debt securities reflects the amount of unrealized loss related to expected credit losses, limited by the amount that fair value is less than the amortized cost basis, and cannot have an associated negative allowance. For certain financial assets, such as residential real estate loans guaranteed by the Government National Mortgage Association (GNMA), an agency of the federal government, U. S. Treasury and Agency mortgage backed debt securities, as well as certain sovereign debt securities, the Company has not recognized an ACL as our expectation of nonpayment of the amortized cost basis, based on historical losses, adjusted for current conditions and reasonable and supportable forecasts, is zero. A financial asset is collateral-dependent when the borrower is experiencing financial difficulty and repayment is expected to be provided substantially through the sale or operation of the collateral. When a collateral-dependent financial asset is probable of foreclosure, we will measure the ACL based on the fair value of the collateral. If we intend to sell the underlying collateral, we will measure the ACL based on the collateral’s net realizable value (fair value of collateral, less estimated costs to sell). In most situations, based on our charge-off policies, we will immediately write-down the financial asset to the fair value of the collateral or net realizable value. For consumer loans, collateral-dependent financial assets may have collateral in the form of residential real estate, automobiles or other personal assets. For commercial loans, collateral-dependent financial assets may have collateral in the form of commercial real estate or other business assets. We do not generally record an ACL for accrued interest receivables because uncollectible accrued interest is reversed through interest income in a timely manner in line with our non-accrual and past due policies for loans and debt securities. For consumer credit card and certain consumer lines of credit, we include an ACL for accrued interest and fees since these loans are not placed on nonaccrual status and written off until the loan is 180 days past due. Accrued interest receivables are included in other assets, except for certain revolving loans, such as credit card loans. COMMERCIAL LOAN PORTFOLIO SEGMENT ACL METHODOLOGY Generally, commercial loans, which include net investments in lease financing, are assessed for estimated losses by grading each loan using various risk factors as identified through periodic reviews. Our estimation approach for the commercial portfolio reflects the estimated probability of default in accordance with the borrower’s financial strength and the severity of loss in the event of default, considering the quality of any underlying collateral. Probability of default and severity at the time of default are statistically derived through historical observations of default and losses after default within each credit risk rating. These estimates are adjusted as appropriate based on additional analysis of long-term average loss experience compared with previously forecasted losses, external loss data or other risks identified from current economic conditions and credit quality trends. The estimated probability of default and severity at the time of default are applied to loan equivalent exposures to estimate losses for unfunded credit commitments. CONSUMER LOAN PORTFOLIO SEGMENT ACL METHODOLOGY For consumer loans, we determine the allowance at the individual loan level. When developing historical loss experience, we pool loans, generally by product types with similar risk characteristics, such as residential real estate mortgages and credit cards. As appropriate and to achieve greater accuracy, we may further stratify selected portfolios by sub-product, origination channel, vintage, loss type, geographic location and other predictive characteristics. We use pooled loan data such as historic delinquency and default and loss severity in the development of our consumer loan models, in addition to home price trends, unemployment trends, and other economic variables that may influence the frequency and severity of losses in the consumer portfolio. AFS PORTFOLIO ACL METHODOLOGY We develop our ACL estimate for AFS debt securities by utilizing a security-level multi-scenario, probability-weighted discounted cash flow model based on a combination of past events, current conditions, as well as reasonable and supportable forecasts. The projected cash flows are discounted at the security’s effective interest rate, except for certain variable rate securities which are discounted using projections of future changes in interest rates, prepayable securities which are adjusted for estimated prepayments, and securities part of a fair value hedge which use hedge-adjusted assumptions. The ACL on an AFS debt security is limited to the difference between its amortized cost basis and fair value (fair value floor) and reversals of the allowance are permitted up to the amount previously recorded. HTM PORTFOLIO ACL METHODOLOGY For most HTM debt securities, the ACL is measured using an expected loss model, similar to the methodology used for loans. Unlike AFS debt securities, the ACL on an HTM debt security is not limited to the fair value floor. Certain beneficial interests categorized as HTM debt securities utilize a similar discounted cash flow model as described for AFS debt securities, without the limitation of the fair value floor. OTHER QUALITATIVE FACTORS The ACL includes amounts for qualitative factors which may not be adequately reflected in our loss models. These amounts represent management’s judgment of risks in the processes and assumptions used in establishing the ACL. Generally, these amounts are established at a granular level below our loan portfolio segments. We also consider economic environmental factors, modeling assumptions and performance, process risk, and other subjective factors, including industry trends and emerging risk assessments. OFF-BALANCE SHEET CREDIT EXPOSURES Our off-balance sheet credit exposures include unfunded loan commitments (generally in the form of revolving lines of credit), financial guarantees not accounted for as insurance contracts or derivatives, including standby letters of credit, and other similar instruments. For off-balance sheet credit exposures, we recognize an ACL associated with the unfunded amounts. We do not recognize an ACL for commitments that are unconditionally cancelable at our discretion. Additionally, we recognize an ACL for financial guarantees that create off-balance sheet credit exposure, such as loans sold with credit recourse and factoring guarantees. ACL for off-balance sheet credit exposures are reported as a liability in accrued expenses and other liabilities on our consolidated balance sheet. OTHER FINANCIAL ASSETS Other financial assets are evaluated for expected credit losses. These other financial assets include accounts receivable for fees, receivables from government-sponsored entities, such as Federal National Mortgage Association (FNMA) and Federal Home Loan Mortgage Corporation (FHLMC), and GNMA, and other accounts receivable from high-credit quality counterparties, such as central clearing counterparties. Many of these financial assets are generally not expected to have an ACL as there is a zero loss expectation (for example, government guarantee) or no historical credit losses. Some financial assets, such as loans to employees, maintain an ACL that is presented on a net basis with the related amortized cost amounts in other assets on our consolidated balance sheet. Given the nature of these financial assets, provision for credit losses is not recognized separately from the regular income or expense associated with these financial assets. Securities purchased under resale agreements are generally over-collateralized by securities or cash and are generally short-term in nature. We have elected the practical expedient for these financial assets given collateral maintenance provisions. These provisions require that we monitor the collateral value and customers are required to replenish collateral, if needed. Accordingly, we generally do not maintain an ACL for these financial assets. PURCHASED CREDIT DETERIORATED FINANCIAL ASSETS Financial assets acquired that are of poor credit quality and with more than an insignificant evidence of credit deterioration since their origination or issuance are PCD assets. PCD assets are recorded at their purchase price plus an ACL estimated at the time of acquisition. Under this approach, there is no provision for credit losses recognized at acquisition; rather, there is a gross-up of the purchase price of the financial asset for the estimate of expected credit losses and a corresponding ACL recorded. Changes in estimates of expected credit losses after acquisition are recognized as provision for credit losses (or reversal of provision for credit losses) in subsequent periods. In general, interest income recognition for PCD financial assets is consistent with interest income recognition for the similar non-PCD financial asset. Troubled Debt Restructuring and Other Relief Related to COVID-19 On March 25, 2020, the U.S. Senate approved the Coronavirus, Aid, Relief, and Economic Security Act (the CARES Act) providing optional, temporary relief from accounting for certain loan modifications as troubled debt restructurings (TDRs). Under the CARES Act, TDR relief is available to banks for loan modifications related to the adverse effects of Coronavirus Disease 2019 (COVID-19) (COVID-related modifications) granted to borrowers that are current as of December 31, 2019. TDR relief applies to COVID-related modifications made from March 1, 2020, until the earlier of December 31, 2020, or 60 days following the termination of the national emergency declared by the President of the United States. In first quarter 2020, we elected to apply the TDR relief provided by the CARES Act. On April 7, 2020, federal banking regulators issued the Interagency Statement on Loan Modifications and Reporting for Financial Institutions Working with Customers Affected by the Coronavirus (Revised) (the Interagency Statement). The guidance in the Interagency Statement provides additional TDR relief as it clarifies that it is not necessary to consider the impact of the COVID-19 pandemic on the financial condition of a borrower in connection with a short-term (e.g., six months or less) COVID-related modification provided the borrower is current at the date the modification program is implemented. For COVID-related modifications in the form of payment deferrals, delinquency status will not advance and loans that were accruing at the time the relief is provided will generally not be placed on nonaccrual status during the deferral period. COVID- related modifications that do not meet the provisions of the CARES Act or the Interagency Statement will be assessed for TDR classification. On April 10, 2020, the FASB Staff issued Accounting for Lease Concessions Related to the Effects of the COVID-19 Pandemic , a question and

Cash, Loan and Dividend Restrictions	Note 3: Cash, Loan and Dividend Restrictions Cash and cash equivalents may be restricted as to usage or withdrawal. Federal Reserve Board (FRB) regulations require that each of our subsidiary banks maintain reserve balances on deposit with the Federal Reserve Banks. Table 3.1 provides a summary of restrictions on cash equivalents in addition to the FRB reserve cash balance requirements . Table 3.1: Nature of Restrictions on Cash Equivalents (in millions) Jun 30, Dec 31, Required reserve balance for the FRB (1) $ — 11,374 Reserve balance for non-U.S. central banks 200 460 Segregated for benefit of brokerage customers under federal and other brokerage regulations 703 733 Related to consolidated variable interest entities (VIEs) that can only be used to settle liabilities of VIEs 26 300 (1) Effective March 26, 2020, the FRB reduced reserve requirement ratios to 0% . The amount for December 31, 2019 represents an average for the year ended December 31, 2019. Federal laws and regulations limit the dividends that a national bank may pay. Our national bank subsidiaries could have declared additional dividends of $1.0 billion at June 30, 2020 , without obtaining prior regulatory approval. We have elected to retain higher capital at our national bank subsidiaries in order to meet internal capital policy minimums and regulatory requirements. Our nonbank subsidiaries are also limited by certain federal and state statutory provisions and regulations covering the amount of dividends that may be paid in any given year. I n addition, under a Support Agreement dated June 28, 2017, as amended and restated on June 26, 2019, among Wells Fargo & Company, the parent holding company (the “Parent”), WFC Holdings, LLC, an intermediate holding company and subsidiary of the Parent (the “IHC”), Wells Fargo Bank, N.A., Wells Fargo Securities, LLC, Wells Fargo Clearing Services, LLC, and certain other direct and indirect subsidiaries of the Parent designated as material entities for resolution planning purposes or identified as related support entities in our resolution plan, the IHC may be restricted from making dividend payments to the Parent if certain liquidity and/or capital metrics fall below defined triggers or if the Parent’s board of directors authorizes it to file a case under the U.S. Bankruptcy Code. Based on retained earnings at June 30, 2020 , our nonbank subsidiaries could have declared additional dividends of $26.5 billion at June 30, 2020 , without obtaining prior regulatory approval. For additional information see Note 3 ( Cash, Loan and Dividend Restrictions) in our 2019 Form 10-K. The FRB’s Capital Plan Rule (codified at 12 CFR 225.8 of Regulation Y) establishes capital planning and other requirements that govern capital distributions including dividends by certain large bank holding companies. The FRB has also published guidance regarding its supervisory expectations for capital planning, including capital policies regarding the process relating to common stock dividend and repurchase decisions in the FRB’s SR Letter 15-18. The Parent’s ability to make certain capital distributions is subject to review by the FRB as part of the Parent’s capital plan in connection with the FRB’s annual Comprehensive Capital Analysis and Review (CCAR). Once the FRB’s stress capital buffer requirement becomes effective on October 1, 2020, the Parent’s ability to take certain capital actions will be subject to the Parent meeting or exceeding certain regulatory capital minimums, which include the stress capital buffer established by the FRB as part of the FRB’s annual supervisory stress test and related CCAR. On July 28, 2020 , the Company reduced its third quarter 2020 common stock dividend to $0.10 per share. On June 25, 2020, the FRB announced that it is requiring large BHCs, including Wells Fargo, to update and resubmit their capital plans within 45 days after the FRB provides updated scenarios. Requiring resubmission will prohibit each BHC from making any capital distribution (excluding any capital distribution arising from the issuance of a capital instrument eligible for inclusion in the numerator of a regulatory capital ratio), unless otherwise approved by the FRB. Through the end of third quarter 2020, the FRB is authorizing each BHC to (i) make share repurchases relating to issuances of common stock related to employee stock ownership plans; (ii) provided that the BHC does not increase the amount of its common stock dividends, pay common stock dividends that do not exceed an amount equal to the average of the BHC’s net income for the four preceding calendar quarters, unless otherwise specified by the FRB; and (iii) make scheduled payments on additional tier 1 and tier 2 capital instruments. These provisions may be extended by the FRB quarter-by-quarter.

AFS and HTM Debt Securities	Note 5: Available-for-Sale and Held-to-Maturity Debt Securities Table 5.1 provides the amortized cost, net of the allowance for credit losses, and fair value by major categories of available-for-sale debt securities, which are carried at fair value, and held-to-maturity debt securities, which are carried at amortized cost, net of allowance for credit losses. The net unrealized gains (losses) for available-for-sale debt securities are reported as a component of cumulative OCI, net of the allowance for credit losses and applicable income taxes. Information on debt securities held for trading is included in Note 4 (Trading Activities). Outstanding balances exclude accrued interest receivable on available-for-sale and held-to-maturity debt securities which are included in other assets. During the first half of 2020 , we reversed accrued interest receivable on our available-for-sale and held-to-maturity debt securities by reversing interest income of $6 million .

For more information, see Note 1 (Summary of Significant Accounting Policies). (3) Realized gains and losses relate to available-for-sale debt securities. There were no realized gains or losses from held-to-maturity debt securities in all periods presented. (4) For the second quarter and first half of 2020 , credit-related impairment recognized in earnings is classified as provision for credit losses due to our adoption of CECL on January 1, 2020. For more information, see Note 1 (Summary of Significant Accounting Policies). Credit Quality We monitor credit quality of debt securities by evaluating various attributes and utilize such information in our evaluation of the appropriateness of the allowance for credit losses. The credit quality indicators that we most closely monitor include credit ratings and delinquency status and are based on information as of our financial statement date. CREDIT RATINGS Credit ratings express opinions about the credit quality of a debt security. We determine the credit rating of a security according to the lowest credit rating made available by national recognized statistical rating organizations (NRSRO). Debt securities rated investment grade, that is those with ratings similar to BBB-/Baa3 or above, as defined by NRSRO, are generally considered by the rating agencies and market participants to be low credit risk. Conversely, debt securities rated below investment grade, labeled as “speculative grade” by the rating agencies, are considered to be distinctively higher credit risk than investment grade debt securities. For debt securities not rated by the NRSRO, we determine an internal credit grade of the debt securities (used for credit risk management purposes) equivalent to the credit ratings assigned by major credit agencies. The fair value of available-for-sale debt securities categorized as investment grade based on internal credit grades was $1.3 billion at June 30, 2020 , and $2.2 billion at December 31, 2019 . Held-to-maturity debt securities categorized as investment grade based on internal credit grades are not significant . If an internal credit grade was not assigned, we categorized the debt security as non-investment grade. Table 5.4 shows the percentage of fair value of available-for-sale debt securities and amortized cost of held-to-maturity debt securities determined by those rated investment grade, inclusive of those based on internal credit grades. Table 5.4: Investment Grade Debt Securities Available-for-Sale Held-to-Maturity ($ in millions) Fair value % investment grade Amortized cost % investment grade June 30, 2020 Total portfolio $ 228,899 99 % 169,022 99 % Breakdown by category: Securities of U.S. Treasury and federal agencies (1) $ 152,818 100 % 153,863 100 % Securities of U.S. states and political subdivisions 33,011 99 14,286 100 Collateralized loan obligations 24,999 100 N/A N/A All other debt securities (2) 18,071 87 873 6 December 31, 2019 Total portfolio $ 263,459 99 % 153,933 99 % Breakdown by category: Securities of U.S. Treasury and federal agencies (1) $ 177,413 100 % 139,619 100 % Securities of U.S. states and political subdivisions 40,337 99 13,486 100 Collateralized loan obligations 29,055 100 N/A N/A All other debt securities (2) 16,654 82 828 4 (1) Includes federal agency mortgage-backed securities. (2) Includes non-agency mortgage-backed, corporate, and all other debt securities. DELINQUENCY STATUS AND NONACCRUAL DEBT SECURITIES Debt security issuers that are delinquent in payment of amounts due under contractual debt agreements have a higher probability of recognition of credit losses. As such, as part of our monitoring of the credit quality of the debt security portfolio, we consider whether debt securities we own are past due in payment of principal or interest payments and whether any securities have been placed into nonaccrual status. We had no debt securities that were past due and still accruing at June 30, 2020 or December 31, 2019 . The fair value of available-for-sale debt securities in nonaccrual status was $153 million and $110 million as of June 30, 2020 , and December 31, 2019 , respectively. There were no held-to-maturity debt securities in nonaccrual status as of June 30, 2020 , or December 31, 2019 . Purchased debt securities with credit deterioration (PCD) are not considered to be in nonaccrual status, as payments from issuers of these securities remain current. Table 5.5 presents detail of available-for-sale debt securities purchased with credit deterioration during the period. There were no available-for-sale debt securities purchased with credit deterioration during second quarter 2020. There were no held-to-maturity debt securities purchased with credit deterioration during the second quarter and first half of 2020 . The amounts presented are as of the date of the PCD assets were purchased.

Debt securities on which we have recorded credit impairment are categorized as being “less than 12 months” or “12 months or more” in a continuous loss position based on the point in time that the fair value declined to below the (1) for the current period presented, amortized cost basis net of allowance for credit losses, or the (2) for the prior period presented, amortized cost basis.

As part of that assessment we evaluated and concluded that we do not intend to sell any of the debt securities, and that it is more likely than not that we will not be required to sell, prior to recovery of the amortized cost basis. We evaluate, where necessary, whether credit impairment exists by comparing the present value of the expected cash flows to the debt securities’ amortized cost basis. In prior periods, credit impairment was recorded as a write-down to the amortized cost basis of the security. In the current period, credit impairment is recorded as an allowance for credit losses. For descriptions of the factors we consider when analyzing debt securities for impairment as well as methodology and significant inputs used to measure credit losses, see Note 1 (Summary of Significant Accounting Policies). Allowance for Credit Losses for Debt Securities Table 5.7 presents the allowance for credit losses on available-for-sale and held-to-maturity debt securities. Table 5.7: Allowance for Credit Losses for Debt Securities Quarter ended June 30, 2020 Six months ended June 30, 2020 (in millions) Available-for-Sale Held-to-Maturity Available-for-Sale Held-to-Maturity Balance, beginning of period (1) $ 161 11 $ — — Cumulative effect from change in accounting policies (2) — — 24 7 Balance, beginning of period, adjusted 161 11 24 7 Provision (reversal of provision) for credit losses (40 ) 9 128 13 Securities purchased with credit deterioration — — 11 — Reduction due to sales (8 ) — (8 ) — Reduction due to intent to sell — — (11 ) — Charge-offs (1 ) — (33 ) — Interest income (3) 2 — 3 — Balance, end of period (4) $ 114 20 $ 114 20 (1) Prior to our adoption of CECL on January 1, 2020, the allowance for credit losses related to available-for-sale and held-to-maturity debt securities was not applicable and is therefore presented as $0 at December 31, 2019. For more information, see Note 1 (Summary of Significant Accounting Policies). (2) Represents the impact of adoption of CECL on January 1, 2020. For more information, see Note 1 (Summary of Significant Accounting Policies). (3) Certain debt securities with an allowance for credit losses calculated by discounting expected cash flows using the securities’ effective interest rate over its remaining life, recognize changes in the allowance for credit losses attributable to the passage of time as interest income. (4) The allowance for credit losses for debt securities largely relates to corporate debt securities as of June 30, 2020 . Contractual Maturities Table 5.8 shows the remaining contractual maturities, amortized cost net of allowance for credit losses, fair value and weighted-average effective yields of available-for-sale debt securities. The remaining contractual principal maturities for MBS do not consider prepayments. Remaining expected maturities will differ from contractual maturities because borrowers may have the right to prepay obligations before the underlying mortgages mature.

Loans and Related Allowance for Credit Losses	Note 6: Loans and Related Allowance for Credit Losses Table 6.1 presents total loans outstanding by portfolio segment and class of financing receivable. Outstanding balances include unearned income, net deferred loan fees or costs, and unamortized discounts and premiums. These amounts were less than 1% of our total loans outstanding at June 30, 2020 , and December 31, 2019 . Outstanding balances exclude accrued interest receivable on loans, except for certain revolving loans, such as credit card loans. During the first half of 2020 , we reversed accrued interest receivable by reversing interest income of $21 million for our commercial portfolio segment and $114 million for our consumer portfolio segment. See Note 9 (Other Assets) for additional information on accrued interest receivable.

The table excludes loans for which we have elected the fair value option and government insured/guaranteed real estate 1-4 family first mortgage loans because their loan activity normally does not impact the ACL. In the first half of 2020 , we sold $1.2 billion of 1-4 family first mortgage loans for a gain of $724 million , which is included in other noninterest income on our consolidated income statement. These whole loans were designated as MLHFS in 2019.

We generally require a fee to extend such commitments. Certain commitments are subject to loan agreements with covenants regarding the financial performance of the customer or borrowing base formulas on an ongoing basis that must be met before we are required to fund the commitment. We may reduce or cancel consumer commitments, including home equity lines and credit card lines, in accordance with the contracts and applicable law. We may, as a representative for other lenders, advance funds or provide for the issuance of letters of credit under syndicated loan or letter of credit agreements. Any advances are generally repaid in less than a week and would normally require default of both the customer and another lender to expose us to loss. The unfunded amount of these temporary advance arrangements totaled approximately $77.8 billion at June 30, 2020 . We issue commercial letters of credit to assist customers in purchasing goods or services, typically for international trade. At June 30, 2020 , and December 31, 2019 , we had $922.6 million and $862 million , respectively, of outstanding issued commercial letters of credit. We also originate multipurpose lending commitments under which borrowers have the option to draw on the facility for different purposes in one of several forms, including a standby letter of credit. See Note 13 (Guarantees, Pledged Assets and Collateral, and Other Commitments) for additional information on standby letters of credit. When we make commitments, we are exposed to credit risk. The maximum credit risk for these commitments will generally be lower than the contractual amount because a significant portion of these commitments are not funded. We manage the potential risk in commitments to lend by limiting the total amount of commitments, both by individual customer and in total, by monitoring the size and maturity structure of these commitments and by applying the same credit standards for these commitments as for all of our credit activities. For loans and commitments to lend, we generally require collateral or a guarantee. We may require various types of collateral, including commercial and consumer real estate, automobiles, other short-term liquid assets such as accounts receivable or inventory and long-lived assets, such as equipment and other business assets. Collateral requirements for each loan or commitment may vary based on the loan product and our assessment of a customer’s credit risk according to the specific credit underwriting, including credit terms and structure. The contractual amount of our unfunded credit commitments, including unissued standby and commercial letters of credit, is summarized by portfolio segment and class of financing receivable in Table 6.4 . The table excludes the issued standby and commercial letters of credit and temporary advance arrangements described above.

On January 1, 2020, we adopted CECL. Additional information on our adoption of CECL is included in Note 1 (Summary of Significant Accounting Policies). In second quarter 2020, ACL for loans increased $8.4 billion driven by current and forecasted economic conditions due to the COVID-19 pandemic. These expected impacts were most significantly affected by anticipated changes to economic variables, as well as higher expected losses in the commercial real estate and consumer real estate mortgage loan portfolios and expected impacts of lower oil prices and deteriorating credit trends on the oil and gas portfolio.

Table 6.7 disaggregates our allowance for credit losses for loans and recorded investment in loans by impairment methodology. This information is no longer relevant after December 31, 2019, given our adoption of CECL on January 1, 2020, which has a single impairment methodology.

Credit Quality We monitor credit quality by evaluating various attributes and utilize such information in our evaluation of the appropriateness of the allowance for credit losses. The following sections provide the credit quality indicators we most closely monitor. The credit quality indicators are generally based on information as of our financial statement date, with the exception of updated Fair Isaac Corporation (FICO) scores and updated loan-to-value (LTV)/combined LTV (CLTV). We obtain FICO scores at loan origination and the scores are generally updated at least quarterly, except in limited circumstances, including compliance with the Fair Credit Reporting Act (FCRA). Generally, the LTV and CLTV indicators are updated in the second month of each quarter, with updates no older than March 31, 2020 . Amounts disclosed in the credit quality tables that follow are not comparative between reported periods due to our adoption of CECL on January 1, 2020. For more information, see Note 1 (Summary of Significant Accounting Policies). COMMERCIAL CREDIT QUALITY INDICATORS We manage a consistent process for assessing commercial loan credit quality. Generally, commercial loans are subject to individual risk assessment using our internal borrower and collateral quality ratings, which is our primary credit quality indicator. Our ratings are aligned to federal banking regulators’ definitions of pass and criticized categories with the criticized category including special mention, substandard, doubtful, and loss categories. Table 6.8 provides a breakdown of outstanding commercial loans by risk category. In connection with our adoption of CECL, credit quality information is provided with the year of origination for term loans. Revolving loans may convert to term loans as a result of a contractual provision in the original loan agreement or if modified in a TDR. At June 30, 2020 , we had $475.0 billion and $38.2 billion of pass and criticized loans respectively.

For more information, see Note 1 (Summary of Significant Accounting Policies). Table 6.9 provides past due information for commercial loans, which we monitor as part of our credit risk management practices; however, delinquency is not a primary credit quality indicator for commercial loans. Payment deferral activities instituted in response to the COVID-19 pandemic may delay recognition of delinquencies for customers who otherwise would have moved into past due status.

Loan delinquency, FICO credit scores and LTV for 1-4 family mortgage loans are the primary credit quality indicators that we monitor and utilize in our evaluation of the appropriateness of the allowance for credit losses for the consumer portfolio segment. Many of our loss estimation techniques used for the allowance for credit losses rely on delinquency-based models; therefore, delinquency is an important indicator of credit quality and the establishment of our allowance for credit losses. Table 6.10 provides the outstanding balances of our consumer portfolio by delinquency status. Payment deferral activities instituted in response to the COVID-19 pandemic may delay recognition of delinquencies for customers who otherwise would have moved into past due status. In connection with our adoption of CECL, credit quality information is provided with the year of origination for term loans. Revolving loans may convert to term loans as a result of a contractual provision in the original loan agreement or if modified in a TDR. The revolving loans converted to term loans in the credit card loan category represent credit card loans with modified terms that require payment over a specific term.

Table 6.11 provides a breakdown of our consumer portfolio by FICO. Substantially all of the scored consumer portfolio has an updated FICO of 680 and above, reflecting a strong current borrower credit profile. FICO is not available for certain loan types, or may not be required if we deem it unnecessary due to strong collateral and other borrower attributes.

For more information, see Note 1 (Summary of Significant Accounting Policies). (2) Represents loans whose repayments are predominantly insured by the FHA or guaranteed by the VA. (3) 41% of the adjusted unpaid principal balance for consumer PCI loans had FICO scores less than 680 and 19% where no FICO was available to us at December 31, 2019 . LTV refers to the ratio comparing the loan’s unpaid principal balance to the property’s collateral value. CLTV refers to the combination of first mortgage and junior lien mortgage (including unused line amounts for credit line products) ratios. LTVs and CLTVs are updated quarterly using a cascade approach which first uses values provided by automated valuation models (AVMs) for the property. If an AVM is not available, then the value is estimated using the original appraised value adjusted by the change in Home Price Index (HPI) for the property location. If an HPI is not available, the original appraised value is used. The HPI value is normally the only method considered for high value properties, generally with an original value of $1 million or more, as the AVM values have proven less accurate for these properties. Table 6.12 shows the most updated LTV and CLTV distribution of the real estate 1-4 family first and junior lien mortgage loan portfolios. We consider the trends in residential real estate markets as we monitor credit risk and establish our allowance for credit losses. In the event of a default, any loss should be limited to the portion of the loan amount in excess of the net realizable value of the underlying real estate collateral value. Certain loans do not have an LTV or CLTV due to industry data availability and portfolios acquired from or serviced by other institutions.

Equity Securities	Note 8: Equity Securities Table 8.1 provides a summary of our equity securities by business purpose and accounting method, including equity securities with readily determinable fair values (marketable) and those without readily determinable fair values (nonmarketable).

In second quarter 2020 , we entered into arrangements to transition our economic hedges of our deferred compensation plan liabilities from equity securities to derivative instruments. (2) Includes $3.8 billion and $4.8 billion at June 30, 2020 , and December 31, 2019 , respectively, related to investments in Federal Reserve Bank and Federal Home Loan Bank stock. (3) Represents nonmarketable equity securities accounted for under the measurement alternative. Equity Securities Held for Trading Equity securities held for trading purposes are marketable equity securities traded on organized exchanges. These securities are held as part of our customer accommodation trading activities. For more information on these activities, see Note 4 (Trading Activities). Equity Securities Not Held for Trading We also hold equity securities unrelated to trading activities. These securities include private equity and tax credit investments, securities held as economic hedges or to meet regulatory requirements (for example, Federal Reserve Bank and Federal Home Loan Bank stock). FAIR VALUE Marketable equity securities held for purposes other than trading consist of exchange-traded equity funds held to economically hedge obligations related to our deferred compensation plans, as well as other holdings of publicly traded equity securities held for investment purposes. We account for certain nonmarketable equity securities under the fair value method, and substantially all of these securities are economically hedged with equity derivatives. EQUITY METHOD Our equity method investments consist of tax credit and private equity investments, the majority of which are our low-income housing tax credit (LIHTC) investments. We invest in affordable housing projects that qualify for the LIHTC, which are designed to promote private development of low-income housing. These investments generate a return mostly through realization of federal tax credit and other tax benefits. In the second quarter and first half of 2020 , we recognized pre-tax losses of $340 million and $679 million , respectively, related to our LIHTC investments, compared with $298 million and $571 million , respectively, for the same periods a year ago. These losses were recognized in other noninterest income. We also recognized total tax benefits of $401 million and $799 million in the second quarter and first half of 2020 , respectively, which included tax credits recorded to income taxes of $317 million and $631 million for the same periods, respectively. In the second quarter and first half of 2019 , total tax benefits were $376 million and $746 million , respectively, which included tax credits of $303 million and $605 million for the same periods, respectively. We are periodically required to provide additional financial support during the investment period. A liability is recognized for unfunded commitments that are both legally binding and probable of funding. These commitments are predominantly funded within three years of initial investment. Our liability for these unfunded commitments was $4.2 billion at June 30, 2020 , and $4.3 billion at December 31, 2019 . This liability for unfunded commitments is included in long-term debt. OTHER The remaining portion of our nonmarketable equity securities portfolio consists of securities accounted for using the cost or measurement alternative. Realized Gains and Losses Not Held for Trading Table 8.2 provides a summary of the net gains and losses from equity securities not held for trading. Gains and losses for securities held for trading are reported in net gains from trading activities.

Transactions with Unconsolidated VIEs Our transactions with unconsolidated VIEs include predominantly securitizations of residential and commercial mortgage loans, and investments in tax credit structures. We have various forms of involvement with VIEs, including servicing, holding senior or subordinated interests, and entering into liquidity arrangements and derivative contracts. Involvements with these unconsolidated VIEs are recorded on our balance sheet in debt and equity securities, loans, MSRs, derivative assets and liabilities, other assets, other liabilities, and long-term debt, as appropriate. Table 10.2 provides a summary of our exposure to unconsolidated VIEs with which we have significant continuing involvement but for which we are not the primary beneficiary. We include transactions where we were the sponsor or servicer and also have other significant forms of continuing involvement. Sponsorship includes transactions where we solely or materially participated in the initial design or structuring of the VIE or marketed the transaction to investors. We consider investments in securities, loans, guarantees, liquidity agreements, commitments and certain derivatives to be other forms of continuing involvement that may be significant. We also include transactions where we transferred assets to a VIE, account for the transfer as a sale, and service the VIE collateral or have other forms of continuing involvement that may be significant (as described above). We exclude certain transactions with unconsolidated VIEs when our continuing involvement is temporary in nature or insignificant in size. We also exclude secured borrowing transactions with unconsolidated VIEs (for information on these transactions, see the Transactions with Consolidated VIEs and Secured Borrowings section in this Note).

Also includes debt interests in the form of both loans and securities. Excludes certain debt securities held related to loans serviced for FNMA, FHLMC and GNMA. (2) Carrying values include assets and related liabilities of $42 million and $556 million at June 30, 2020 , and December 31, 2019 , respectively, related to certain unexercised unconditional repurchase options. These amounts represent the carrying value of the loans and associated debt that would be payable if the option was exercised to repurchase eligible loans from GNMA residential and multifamily loan securitizations. These amounts are excluded from maximum exposure to loss as we are not obligated to exercise the options. In Table 10.2 , “Total VIE assets” represents the remaining principal balance of assets held by unconsolidated VIEs using the most current information available. For VIEs that obtain exposure to assets synthetically through derivative instruments, the notional amount of the derivative is included in the asset balance. “Carrying value” is the amount in our consolidated balance sheet related to our involvement with the unconsolidated VIEs. “Maximum exposure to loss” is determined as the carrying value of our investment in the VIEs excluding the unconditional repurchase options that have not been exercised, plus the remaining undrawn liquidity and lending commitments, the notional amount of net written derivative contracts, and generally the notional amount of, or stressed loss estimate for, other commitments and guarantees. It represents estimated loss that would be incurred under severe, hypothetical circumstances, for which we believe the possibility is extremely remote, such as where the value of our interests and any associated collateral declines to zero, without any consideration of recovery or offset from any economic hedges. Accordingly, this disclosure is not an indication of expected loss. For complete descriptions of our transactions with unconsolidated VIEs with which we have a significant continuing involvement, but we are not the primary beneficiary, see Note 10 (Securitizations and Variable Interest Entities) in our 2019 Form 10-K. Loan Sales and Securitization Activity We periodically transfer consumer and commercial loans and other types of financial assets in securitization and whole loan sale transactions. We typically retain the servicing rights from these sales and may continue to hold other beneficial interests in the transferred financial assets. We may also provide liquidity to investors in the beneficial interests and credit enhancements. Through these transfers we may be exposed to liability under limited amounts of recourse as well as standard representations and warranties we make to purchasers and issuers. Table 10.3 presents information about transfers of assets during the period to unconsolidated VIEs or third-party investors for which we recorded the transfers as sales and have continuing involvement with the transferred assets. In connection with these transfers, we recorded servicing assets, securities, and a liability for repurchase losses which reflects management’s estimate of probable losses related to various representations and warranties for the loans transferred. Each of these interests are initially measured at fair value. Servicing rights are classified as Level 3 measurements, and generally securities are initially classified as Level 2. Sales with continuing involvement include securitizations of conforming residential mortgages that are sold to the government-sponsored entities (GSEs) or GNMA. Substantially all transfers to these entities resulted in no gain or loss because the loans were already measured at fair value on a recurring basis. Table 10.3: Transfers With Continuing Involvement (in millions) 2020 2019 Quarter ended June 30, Residential mortgages Commercial mortgages Residential mortgages Commercial mortgages Net gains (losses) on sale $ — 64 46 74 Asset balances sold 63,584 2,505 36,672 3,358 Servicing rights recognized 443 48 387 33 Securities recognized (1) (263 ) 12 2,482 — Liability for repurchase losses recognized 4 — 5 — Six months ended June 30, Net gains (losses) on sale $ 52 133 60 121 Asset balances sold 111,441 5,233 70,775 6,060 Servicing rights recognized 889 82 707 59 Securities recognized (1) 2,050 74 3,394 — Liability for repurchase losses recognized 7 — 8 — (1) Includes securities retained upon initial transfer and subsequent sales during the periods presented, which may result in a net reduction of securities recognized. Table 10.4 presents the key weighted-average assumptions we used to measure residential MSRs at the date of securitization. Table 10.4: Residential Mortgage Servicing Rights Residential mortgage servicing rights 2020 2019 Quarter ended June 30, Prepayment speed (1) 15.0 % 13.5 Discount rate 7.0 7.5 Cost to service ($ per loan) (2) $ 97 121 Six months ended June 30, Prepayment speed (1) 14.0 % 13.5 Discount rate 6.8 7.7 Cost to service ($ per loan) (2) $ 94 109 (1) The prepayment speed assumption for residential MSRs includes a blend of prepayment speeds and default rates. Prepayment speed assumptions are influenced by mortgage interest rate inputs as well as our estimation of drivers of borrower behavior. (2) Includes costs to service and unreimbursed foreclosure costs, which can vary period to period due to changes in model assumptions and the mix of modified government-guaranteed loans sold to GNMA. Table 10.5 presents the proceeds related to transfers accounted for as sales in which we have continuing involvement with the transferred financial assets, as well as current period cash flows from continuing involvement with previous transfers accounted for as sales. Cash flows from other interests held predominantly include principal and interest payments received on retained bonds. Repurchases of assets represents cash paid to repurchase loans from investors under representation and warranty obligations or in connection with the exercise of cleanup calls on securitizations. Loss reimbursements is cash paid to reimburse investors for losses on individual loans that are already liquidated. Government insured loans are delinquent loans that we service and have exercised our option to purchase out of GNMA pools. These loans are insured by the FHA or guaranteed by the VA.

Retained Interests from Unconsolidated VIEs Table 10.6 provides key economic assumptions and the sensitivity of the current fair value of residential MSRs and other interests held related to unconsolidated VIEs to immediate adverse changes in those assumptions. Amounts for residential MSRs include purchased servicing rights as well as servicing rights resulting from the transfer of loans. See Note 16 (Fair Values of Assets and Liabilities) for additional information on key economic assumptions for residential MSRs. “Other interests held” were obtained when we securitized residential and commercial mortgage loans. Residential mortgage-backed securities retained in securitizations issued through GSEs or GNMA, are excluded from the table because these securities have a remote risk of credit loss due to the GSE or government guarantee. These securities also have economic characteristics similar to GSE or GNMA mortgage-backed securities that we purchase, which are not included in the table. Subordinated interests include only those bonds whose credit rating was below AAA by a major rating agency at issuance. Senior interests include only those bonds whose credit rating was AAA by a major rating agency at issuance. The information presented excludes trading positions held in inventory.

Prepayment assumptions do not significantly impact values of commercial MSRs and commercial mortgage bonds as commercial loans generally include contractual restrictions on prepayment. Servicing costs are not a driver of our MSR value as we are typically primary or master servicer; the higher costs of servicing delinquent and foreclosed loans is generally borne by the special servicer. The primary economic driver impacting the fair value of our commercial MSRs is forward interest rates, which are derived from market observable yield curves used to price capital markets instruments. Market interest rates significantly affect interest earned on custodial deposit balances. The sensitivity of the current fair value of our commercial MSRs to a hypothetical immediate adverse 25% change in the assumption about interest earned on deposit balances at June 30, 2020 , and December 31, 2019 , would result in a decrease in fair value of $94 million and $205 million , respectively. See Note 11 (Mortgage Banking Activities) for further information on our commercial MSRs. The sensitivities in the preceding paragraph and table are hypothetical and caution should be exercised when relying on this data. Changes in value based on variations in assumptions generally cannot be extrapolated because the relationship of the change in the assumption to the change in value may not be linear. Also, the effect of a variation in a particular assumption on the value of the other interests held is calculated independently without changing any other assumptions. In reality, changes in one factor may result in changes in others (for example, changes in prepayment speed estimates could result in changes in the credit losses), which might magnify or counteract the sensitivities. Off-Balance Sheet Loans Table 10.7 presents information about the principal balances of off-balance sheet loans that were sold or securitized, including residential mortgage loans sold to FNMA, FHLMC, GNMA and other investors, for which we have some form of continuing involvement (including servicer). Delinquent loans include loans 90 days or more past due and loans in bankruptcy, regardless of delinquency status. In accordance with applicable servicing guidelines, delinquency status continues to advance for loans with COVID-related payment deferrals. For loans sold or securitized where servicing is our only form of continuing involvement, we would only experience a loss if we were required to repurchase a delinquent loan or foreclosed asset due to a breach in representations and warranties associated with our loan sale or servicing contracts.

(2) Net charge-offs exclude loans sold to FNMA, FHLMC and GNMA as we do not service or manage the underlying real estate upon foreclosure and, as such, do not have access to net charge-off information. (3) At June 30, 2020 , and December 31, 2019 , the table includes total loans of $1.0 trillion at both dates, delinquent loans of $51.3 billion and $5.2 billion , respectively, and foreclosed assets of $224 million and $251 million , respectively, for FNMA, FHLMC and GNMA. Transactions with Consolidated VIEs and Secured Borrowings Table 10.8 presents a summary of financial assets and liabilities for asset transfers accounted for as secured borrowings and involvements with consolidated VIEs. Carrying values of “Assets” are presented using GAAP measurement methods, which may include fair value, credit impairment or other adjustments, and therefore in some instances will differ from “Total VIE assets.” For VIEs that obtain exposure synthetically through derivative instruments, the notional amount of the derivative is included in “Total VIE assets.” On the consolidated balance sheet, we separately disclose the consolidated assets of certain VIEs that can only be used to settle the liabilities of those VIEs.

We also consolidate VIEs where we are the primary beneficiary. In certain transactions, we provide contractual support in the form of limited recourse and liquidity to facilitate the remarketing of short-term securities issued to third-party investors. Other than this limited contractual support, the assets of the VIEs are the sole source of repayment of the securities held by third parties. For complete descriptions of our accounting for transfers accounted for as secured borrowings and involvement with consolidated VIEs, see Note 10 (Securitizations and Variable Interest Entities) in our 2019 Form 10-K. Other Transactions In addition to the transactions included in the previous tables, we have used wholly-owned trust preferred security VIEs to issue debt securities or preferred equity exclusively to third-party investors. As the sole assets of the VIEs are receivables from us, we do not consolidate the VIEs even though we own all of the voting equity shares of the VIEs, have fully guaranteed the obligations of the VIEs, and may have the right to redeem the third-party securities under certain circumstances. In our consolidated balance sheet we reported the debt securities issued to the VIEs as long-term junior subordinated debt with a carrying value of $692 million and $2.1 billion at June 30, 2020 , and December 31, 2019 , respectively. During first quarter 2020, we liquidated certain of our trust preferred security VIEs. As part of these liquidations, the preferred securities issued by the trusts were canceled and junior subordinated debentures with a total carrying value of $1.4 billion were distributed to the preferred security holders. Prior to the liquidations, we held $10 million of these preferred securities, which were exchanged for junior subordinated debentures upon liquidation and subsequently retired with no impact to earnings. See Note 17 (Preferred Stock) for additional information about trust preferred securities. Certain money market funds are also excluded from the previous tables because they are exempt from the consolidation analysis. We voluntarily waived a portion of our management fees for these money market funds to maintain a minimum level of daily net investment income. The amount of fees waived was $22 million and $33 million in the second quarter and first half of 2020 , respectively, compared with $10 million and $20 million

Mortgage Banking Activities [Abstract]
Mortgage Banking Activities	Note 11: Mortgage Banking Activities Mortgage banking activities consist of residential and commercial mortgage originations, sales and servicing. We apply the amortization method to commercial MSRs and the fair value method to residential MSRs. Table 11.1 presents the changes in MSRs measured using the fair value method. Table 11.1: Analysis of Changes in Fair Value MSRs Quarter ended June 30, Six months ended June 30, (in millions) 2020 2019 2020 2019 Fair value, beginning of period $ 8,126 13,336 $ 11,517 14,649 Servicing from securitizations or asset transfers (1) 462 400 923 741 Sales and other (2) (1 ) (1 ) (32 ) (282 ) Net additions 461 399 891 459 Changes in fair value: Due to valuation inputs or assumptions: Mortgage interest rates (3) (600 ) (1,153 ) (3,622 ) (2,093 ) Servicing and foreclosure costs (4) (349 ) (22 ) (422 ) (10 ) Discount rates — (109 ) 27 (9 ) Prepayment estimates and other (5) (182 ) 206 (371 ) 143 Net changes in valuation inputs or assumptions (1,131 ) (1,078 ) (4,388 ) (1,969 ) Changes due to collection/realization of expected cash flows (6) (637 ) (561 ) (1,201 ) (1,043 ) Total changes in fair value (1,768 ) (1,639 ) (5,589 ) (3,012 ) Fair value, end of period $ 6,819 12,096 $ 6,819 12,096 (1) Includes impacts associated with exercising cleanup calls on securitizations and our right to repurchase delinquent loans from GNMA loan securitization pools. MSRs may increase upon repurchase due to servicing liabilities associated with these delinquent GNMA loans. (2) Includes sales and transfers of MSRs, which can result in an increase in MSRs if related to portfolios with servicing liabilities. (3) Includes prepayment speed changes as well as other valuation changes due to changes in mortgage interest rates. (4) Includes costs to service and unreimbursed foreclosure costs. (5) Represents other changes in valuation model inputs or assumptions including prepayment speed estimation changes that are independent of mortgage interest rate changes. (6) Represents the reduction in the MSR fair value for the cash flows expected to be collected during the period, net of income accreted due to the passage of time. Table 11.2 presents the changes in amortized MSRs. Table 11.2: Analysis of Changes in Amortized MSRs Quarter ended June 30, Six months ended June 30, (in millions) 2020 2019 2020 2019 Balance, beginning of period $ 1,406 1,427 $ 1,430 1,443 Purchases 7 16 15 40 Servicing from securitizations or asset transfers 48 33 82 59 Amortization (1) (100 ) (69 ) (166 ) (135 ) Balance, end of period $ 1,361 1,407 $ 1,361 1,407 Fair value of amortized MSRs: Beginning of period $ 1,490 2,149 $ 1,490 2,288 End of period 1,401 1,897 1,401 1,897 (1) Commercial amortized MSRs are evaluated for impairment purposes by the following risk strata: agency (GSEs) for multi-family properties and non-agency. There was a $30 million impairment and associated valuation allowance recorded in the second quarter and first half of 2020 on the commercial amortized MSRs. We present the components of our managed servicing portfolio in Table 11.3 at unpaid principal balance for loans serviced and subserviced for others and at book value for owned loans serviced.

As the servicer of loans for others, we advance certain payments of principal, interest, taxes, insurance, and default-related expenses which are generally reimbursed within a short timeframe from cash flows from the trust, GSEs, insurer or borrower. The credit risk related to these advances is limited since the reimbursement is generally senior to cash payments to investors. We also advance payments of taxes and insurance for our owned loans which are collectible from the borrower. We maintain an allowance for uncollectible amounts for advances on loans serviced for others that may not be reimbursed if the payments were not made in accordance with applicable servicing agreements or if the insurance or servicing agreements contain limitations on reimbursements. Servicing advances on owned loans are charged-off when deemed uncollectible. Table 11.4 presents the components of mortgage banking noninterest income.

Guarantees [Abstract]
Guarantees, Pledged Assets and Collateral, and Other Commitments	Note 13: Guarantees, Pledged Assets and Collateral, and Other Commitments Guarantees are contracts that contingently require us to make payments to a guaranteed party based on an event or a change in an underlying asset, liability, rate or index. Guarantees are generally in the form of standby and direct pay letters of credit, written options, recourse obligations, and other types of similar arrangements. For complete descriptions of our guarantees, see Note 16 (Guarantees, Pledged Assets and Collateral, and Other Commitments) in our 2019 Form 10-K. Table 13.1 shows carrying value, maximum exposure to loss on our guarantees and the related non-investment grade amounts. Table 13.1: Guarantees – Carrying Value and Maximum Exposure to Loss Maximum exposure to loss (in millions) Carrying value of obligation (asset) Expires in one year or less Expires after one year through three years Expires after three years through five years Expires after five years Total Non- investment grade June 30, 2020 Standby letters of credit $ 178 12,171 4,447 2,051 426 19,095 7,689 Direct pay letters of credit 72 1,846 3,475 971 39 6,331 1,224 Written options (1) (49 ) 15,916 10,481 2,495 357 29,249 19,223 Loans and MLHFS sold with recourse (2) 31 122 722 1,714 9,957 12,515 10,363 Exchange and clearing house guarantees — — — — 5,296 5,296 — Other guarantees and indemnifications (3) 1 444 1 1 1,389 1,835 426 Total guarantees $ 233 30,499 19,126 7,232 17,464 74,321 38,925 December 31, 2019 Standby letters of credit $ 36 11,569 4,460 2,812 467 19,308 7,104 Direct pay letters of credit — 1,861 3,815 824 105 6,605 1,184 Written options (1) (345 ) 17,088 10,869 2,341 273 30,571 18,113 Loans and MLHFS sold with recourse (2) 52 114 576 1,356 10,050 12,096 9,835 Exchange and clearing house guarantees — — — — 4,817 4,817 — Other guarantees and indemnifications (3) 1 785 1 3 809 1,598 698 Total guarantees $ (256 ) 31,417 19,721 7,336 16,521 74,995 36,934 (1) Written options, which are in the form of derivatives, are also included in the derivative disclosures in Note 15 (Derivatives). Carrying value net asset position is a result of certain deferred premium option trades. (2) Represent recourse provided, predominantly to the GSEs, on loans sold under various programs and arrangements. (3) Includes indemnifications provided to certain third-party clearing agents. Outstanding customer obligations under these arrangements were $77 million and $80 million with related collateral of $1.3 billion and $696 million at June 30, 2020 , and December 31, 2019 , respectively. “Maximum exposure to loss” and “Non-investment grade” are required disclosures under GAAP. Maximum exposure to loss represents the estimated loss that would be incurred under an assumed hypothetical circumstance, despite what we believe is a remote possibility, where the value of our interests and any associated collateral declines to zero. Maximum exposure to loss estimates in Table 13.1 do not reflect economic hedges or collateral we could use to offset or recover losses we may incur under our guarantee agreements. Accordingly, this required disclosure is not an indication of expected loss. We believe the carrying value is more representative of our exposure to loss than maximum exposure to loss. The carrying value represents the fair value of the guarantee, if any, and also includes an ACL for guarantees, if applicable. Non-investment grade represents those guarantees on which we have a higher risk of performance under the terms of the guarantee. If the underlying assets under the guarantee are non-investment grade (that is, an external rating that is below investment grade or an internal credit default grade that is equivalent to a below investment grade external rating), we consider the risk of performance to be high. Internal credit default grades are determined based upon the same credit policies that we use to evaluate the risk of payment or performance when making loans and other extensions of credit. Credit quality indicators we usually consider in evaluating risk of payments or performance are described in Note 6 (Loans and Related Allowance for Credit Losses). We provide debit and credit card transaction processing services through the payment networks directly for merchants and as a sponsor for merchant processing servicers, including our joint venture with a third party that is accounted for as an equity method investment. In our role as the merchant acquiring bank, we have a potential obligation for payment and delivery disputes between the merchant and the cardholder that are resolved in favor of the cardholder. If we are unable to collect the amounts from the merchant, we incur a loss for the refund to the cardholder. We are secondarily obligated to make a refund for transactions involving the sponsored merchant processing servicers. We have a low likelihood of loss since most products and services are delivered when purchased and amounts are refunded when items are returned to the merchant. In addition, we may reduce our risk by withholding future payments and requiring cash or other collateral. For the first half of 2020 , we processed card transaction volume of $608.3 billion as a merchant acquiring bank, and related losses, including those from our joint venture entity, were immaterial. The Parent fully and unconditionally guarantees the payment of principal, interest, and any other amounts that may be due on securities that its 100% owned finance subsidiary, Wells Fargo Finance LLC, may issue. These guaranteed liabilities were $2.4 billion and $1.6 billion at June 30, 2020 and December 31, 2019 , respectively. These guarantees rank on parity with all of the Parent’s other unsecured and unsubordinated indebtedness. Pledged Assets Table 13.2 provides the carrying amount of on-balance sheet pledged assets and the fair value of other pledged collateral. Other pledged collateral is collateral we have received from third parties, have the right to repledge and is not recognized on our balance sheet. TRADING RELATED ACTIVITY Our trading businesses may pledge debt and equity securities in connection with securities sold under agreements to repurchase (repurchase agreements) and securities lending arrangements. The collateral that we pledge related to our trading activities may include our own collateral as well as collateral that we have received from third parties and have the right to repledge. All of the trading activity pledged collateral is eligible to be repledged or sold by the secured party. NON-TRADING RELATED ACTIVITY As part of our liquidity management strategy, we may pledge loans, debt securities, and other assets to secure trust and public deposits, borrowings and letters of credit from the Federal Home Loan Bank (FHLB) and FRB and for other purposes as required or permitted by law or insurance statutory requirements. Substantially all of the non-trading activity pledged collateral is not eligible to be repledged or sold by the secured party. VIE RELATED We pledge assets in connection with various types of transactions entered into with VIEs. These pledged assets can only be used to settle the liabilities of those entities. We also have loans recorded on our balance sheet which represent certain delinquent loans that are eligible for repurchase from GNMA loan securitizations. See Note 10 (Securitizations and Variable Interest Entities) for additional information on consolidated VIE assets and VIEs accounted for as secured borrowings. Table 13.2: Pledged Assets (in millions) Jun 30, Dec 31, Related to trading activities: Repledged third-party owned debt and equity securities $ 41,952 60,083 Trading debt securities and other 22,847 51,083 Equity securities 971 1,379 Total pledged assets related to trading activities 65,770 112,545 Related to non-trading activities: Loans 406,496 406,106 Debt securities: Available-for-sale 54,455 61,126 Held-to-maturity 2,826 3,685 Mortgage loans held for sale 181 2,266 Total pledged assets related to non-trading activities 463,958 473,183 Related to VIEs: Consolidated VIE assets 12,447 14,368 VIEs accounted for as secured borrowings 74 80 Loans eligible for repurchase from GNMA securitizations 54 568 Total pledged assets related to VIEs 12,575 15,016 Total pledged assets $ 542,303 600,744 Securities Financing Activities We enter into resale and repurchase agreements and securities borrowing and lending agreements (collectively, “securities financing activities”) typically to finance trading positions (including securities and derivatives), acquire securities to cover short trading positions, accommodate customers’ financing needs, and settle other securities obligations. These activities are conducted through our broker-dealer subsidiaries and to a lesser extent through other bank entities. Our securities financing activities primarily involve high quality, liquid securities such as U.S. Treasury securities and government agency securities, and to a lesser extent, less liquid securities, including equity securities, corporate bonds and asset-backed securities. We account for these transactions as collateralized financings in which we typically receive or pledge securities as collateral. We believe these financing transactions generally do not have material credit risk given the collateral provided and the related monitoring processes. OFFSETTING OF SECURITIES FINANCING ACTIVITIES Table 13.3 presents resale and repurchase agreements subject to master repurchase agreements (MRA) and securities borrowing and lending agreements subject to master securities lending agreements (MSLA). Collateralized financings with a single counterparty are presented net on our balance sheet, provided certain criteria are met that permit balance sheet netting. Most transactions subject to these agreements do not meet those criteria and thus are not eligible for balance sheet netting. Collateral we pledged consists of non-cash instruments, such as securities or loans, and is not netted on the balance sheet against the related liability. Collateral we received includes securities or loans and is not recognized on our balance sheet. Collateral pledged or received may be increased or decreased over time to maintain certain contractual thresholds, as the assets underlying each arrangement fluctuate in value. Generally, these agreements require collateral to exceed the asset or liability recognized on the balance sheet. The following table includes the amount of collateral pledged or received related to exposures subject to enforceable MRAs or MSLAs. While these agreements are typically over-collateralized, U.S. GAAP requires disclosure in this table to limit the reported amount of such collateral to the amount of the related recognized asset or liability for each counterparty. In addition to the amounts included in Table 13.3 , we also have balance sheet netting related to derivatives that is disclosed in Note 15 (Derivatives). Table 13.3: Offsetting – Securities Financing Activities (in millions) Jun 30, Dec 31, Assets: Resale and securities borrowing agreements Gross amounts recognized $ 110,900 140,773 Gross amounts offset in consolidated balance sheet (1) (13,640 ) (19,180 ) Net amounts in consolidated balance sheet (2) 97,260 121,593 Collateral not recognized in consolidated balance sheet (3) (96,541 ) (120,786 ) Net amount (4) $ 719 807 Liabilities: Repurchase and securities lending agreements Gross amounts recognized $ 63,028 111,038 Gross amounts offset in consolidated balance sheet (1) (13,640 ) (19,180 ) Net amounts in consolidated balance sheet (5) 49,388 91,858 Collateral pledged but not netted in consolidated balance sheet (6) (49,147 ) (91,709 ) Net amount (4) $ 241 149 (1) Represents recognized amount of resale and repurchase agreements with counterparties subject to enforceable MRAs that have been offset in the consolidated balance sheet. (2) Includes $79.3 billion and $102.1 billion classified on our consolidated balance sheet in federal funds sold and securities purchased under resale agreements at June 30, 2020 , and December 31, 2019 , respectively. Also includes securities purchased under long-term resale agreements (generally one year or more) classified in loans, which totaled $18.0 billion and $19.5 billion , at June 30, 2020 , and December 31, 2019 , respectively. (3) Represents the fair value of collateral we have received under enforceable MRAs or MSLAs, limited in the table above to the amount of the recognized asset due from each counterparty. At June 30, 2020 , and December 31, 2019 , we have received total collateral with a fair value of $122.5 billion and $150.9 billion , respectively, all of which we have the right to sell or repledge. These amounts include securities we have sold or repledged to others with a fair value of $41.1 billion at June 30, 2020 , and $59.1 billion at December 31, 2019 . (4) Represents the amount of our exposure (assets) or obligation (liabilities) that is not collateralized and/or is not subject to an enforceable MRA or MSLA. (5) Amount is classified in short-term borrowings on our consolidated balance sheet. (6) Represents the fair value of collateral we have pledged, related to enforceable MRAs or MSLAs, limited in the table above to the amount of the recognized liability owed to each counterparty. At June 30, 2020 , and December 31, 2019 , we have pledged total collateral with a fair value of $64.3 billion and $113.3 billion , respectively, substantially all of which may be sold or repledged by the counterparty. REPURCHASE AND SECURITIES LENDING AGREEMENTS Securities sold under repurchase agreements and securities lending arrangements are effectively short-term collateralized borrowings. In these transactions, we receive cash in exchange for transferring securities as collateral and recognize an obligation to reacquire the securities for cash at the transaction’s maturity. These types of transactions create risks, including (1) the counterparty may fail to return the securities at maturity, (2) the fair value of the securities transferred may decline below the amount of our obligation to reacquire the securities, and therefore create an obligation for us to pledge additional amounts, and (3) the counterparty may accelerate the maturity on demand, requiring us to reacquire the security prior to contractual maturity. We attempt to mitigate these risks in various ways. Our collateral primarily consists of highly liquid securities. In addition, we underwrite and monitor the financial strength of our counterparties, monitor the fair value of collateral pledged relative to contractually required repurchase amounts, and monitor that our collateral is properly returned through the clearing and settlement process in advance of our cash repayment. Table 13.4 provides the gross amounts recognized on the balance sheet (before the effects of offsetting) of our liabilities for repurchase and securities lending agreements disaggregated by underlying collateral type. Table 13.4: Gross Obligations by Underlying Collateral Type (in millions) Jun 30, Dec 31, Repurchase agreements: Securities of U.S. Treasury and federal agencies $ 33,757 48,161 Securities of U.S. States and political subdivisions 54 104 Federal agency mortgage-backed securities 9,751 44,737 Non-agency mortgage-backed securities 1,103 1,818 Corporate debt securities 9,273 7,126 Asset-backed securities 1,008 1,844 Equity securities 1,399 1,674 Other 363 705 Total repurchases 56,708 106,169 Securities lending arrangements: Securities of U.S. Treasury and federal agencies 38 163 Federal agency mortgage-backed securities 18 — Corporate debt securities 97 223 Equity securities (1) 6,164 4,481 Other 3 2 Total securities lending 6,320 4,869 Total repurchases and securities lending $ 63,028 111,038 (1) Equity securities are generally exchange traded and represent collateral received from third parties that has been repledged.

Table 13.5: Contractual Maturities of Gross Obligations (in millions) Overnight/continuous Up to 30 days 30-90 days >90 days Total gross obligation June 30, 2020 Repurchase agreements $ 44,823 3,430 4,970 3,485 56,708 Securities lending arrangements 5,771 — 549 — 6,320 Total repurchases and securities lending (1) $ 50,594 3,430 5,519 3,485 63,028 December 31, 2019 Repurchase agreements $ 79,793 17,681 4,825 3,870 106,169 Securities lending arrangements 4,724 — 145 — 4,869 Total repurchases and securities lending (1) $ 84,517 17,681 4,970 3,870 111,038 (1) Securities lending is executed under agreements that allow either party to terminate the transaction without notice, while repurchase agreements have a term structure to them that technically matures at a point in time. The overnight/continuous repurchase agreements require election of both parties to roll the trade rather than the election to terminate the arrangement as in securities lending. OTHER COMMITMENTS To meet the financing needs of our customers, we may enter into commitments to purchase debt and equity securities to provide capital for their funding, liquidity or other future needs. As of June 30, 2020 , and December 31, 2019 , we had commitments to purchase debt securities of $18 million in both periods and commitments to purchase equity securities of $3.3 billion and $2.7 billion , respectively. As part of maintaining our memberships in certain clearing organizations, we are required to stand ready to provide liquidity to sustain market clearing activity in the event unforeseen events occur or are deemed likely to occur. Certain of these obligations are guarantees of other members’ performance and accordingly are included in Other guarantees and indemnifications in Table 13.1 . Also, we have commitments to purchase loans and securities under resale agreements from certain counterparties, including central clearing organizations. The amount of our unfunded contractual commitments was $14.1 billion and $7.5 billion as of June 30, 2020 , and December 31, 2019 , respectively. Given the nature of these commitments, they are excluded from Table 6.4 (Unfunded Credit Commitments) in Note 6 (Loans and Related Allowance for Credit Losses).

Commitments and Contingencies Disclosure [Abstract]
Legal Actions	Note 14: Legal Actions Wells Fargo and certain of our subsidiaries are involved in a number of judicial, regulatory, governmental, arbitration, and other proceedings or investigations concerning matters arising from the conduct of our business activities, and many of those proceedings and investigations expose Wells Fargo to potential financial loss. These proceedings and investigations include actions brought against Wells Fargo and/or our subsidiaries with respect to corporate-related matters and transactions in which Wells Fargo and/or our subsidiaries were involved. In addition, Wells Fargo and our subsidiaries may be requested to provide information or otherwise cooperate with government authorities in the conduct of investigations of other persons or industry groups. Although there can be no assurance as to the ultimate outcome, Wells Fargo and/or our subsidiaries have generally denied, or believe we have a meritorious defense and will deny, liability in all significant legal actions pending against us, including the matters described below, and we intend to defend vigorously each case, other than matters we describe as having settled. We establish accruals for legal actions when potential losses associated with the actions become probable and the costs can be reasonably estimated. For such accruals, we record the amount we consider to be the best estimate within a range of potential losses that are both probable and estimable; however, if we cannot determine a best estimate, then we record the low end of the range of those potential losses. The actual costs of resolving legal actions may be substantially higher or lower than the amounts accrued for those actions. ATM ACCESS FEE LITIGATION In October 2011, plaintiffs filed a putative class action, Mackmin, et al. v. Visa, Inc. et al. , against Wells Fargo & Company, Wells Fargo Bank, N.A., Visa, MasterCard, and several other banks in the United States District Court for the District of Columbia. Plaintiffs allege that the Visa and MasterCard requirement that if an ATM operator charges an access fee on Visa and MasterCard transactions, then that fee cannot be greater than the access fee charged for transactions on other networks, violates antitrust rules. Plaintiffs seek treble damages, restitution, injunctive relief, and attorneys’ fees where available under federal and state law. Two other antitrust cases that make similar allegations were filed in the same court, but these cases did not name Wells Fargo as a defendant. On February 13, 2013, the district court granted defendants’ motions to dismiss the three actions. Plaintiffs appealed the dismissals and, on August 4, 2015, the United States Court of Appeals for the District of Columbia Circuit vacated the district court’s decisions and remanded the three cases to the district court for further proceedings. On June 28, 2016, the United States Supreme Court granted defendants’ petitions for writ of certiorari to review the decisions of the United States Court of Appeals for the District of Columbia. On November 17, 2016, the United States Supreme Court dismissed the petitions as improvidently granted, and the three cases returned to the district court for further proceedings. On March 18, 2020 , the Company reached a settlement in principle pursuant to which the Company will pay $20.8 million to resolve the cases, subject to final documentation of the settlement agreement. AUTOMOBILE LENDING MATTERS On April 20, 2018, the Company entered into consent orders with the Office of the Comptroller of the Currency (OCC) and the Consumer Financial Protection Bureau (CFPB) to resolve, among other things, investigations by the agencies into the Company’s compliance risk management program and its past practices involving certain automobile collateral protection insurance (CPI) policies and certain mortgage interest rate lock extensions. The consent orders require remediation to customers and the payment of a total of $1.0 billion in civil money penalties to the agencies. In July 2017, the Company announced a plan to remediate customers who may have been financially harmed due to issues related to automobile CPI policies purchased through a third-party vendor on their behalf. Multiple putative class action cases alleging, among other things, unfair and deceptive practices relating to these CPI policies, have been filed against the Company and consolidated into one multi-district litigation in the United States District Court for the Central District of California. The Company has reached an agreement to resolve the multi-district litigation pursuant to which the Company has agreed to pay, consistent with its remediation obligations under the consent orders, approximately $609 million in remediation to customers with CPI policies placed between October 15, 2005, and September 30, 2016. The settlement amount is not incremental to the Company’s remediation obligations under the consent orders, but instead encompasses those obligations, including remediation payments to date. The settlement amount is subject to change as the Company finalizes its remediation activity under the consent orders. In addition, the Company has agreed to contribute $1 million to a common fund for the class. The district court granted final approval of the settlement on November 21, 2019. A putative class of shareholders also filed a securities fraud class action against the Company and its executive officers alleging material misstatements and omissions of CPI-related information in the Company’s public disclosures. In January 2020, the court dismissed this action as to all defendants except the Company and a former executive officer and limited the action to two alleged misstatements. In addition, the Company is subject to a class action lawsuit in the United States District Court for the Central District of California alleging that customers are entitled to refunds related to the unused portion of guaranteed automobile protection (GAP) waiver or insurance agreements between the customer and dealer and, by assignment, the lender. Allegations related to the CPI and GAP programs are among the subjects of shareholder derivative lawsuits pending in federal and state court in California. The court dismissed the state court action in September 2018, but plaintiffs filed an amended complaint in November 2018. The parties to the state court action have entered into an agreement to resolve the action pursuant to which the Company will pay plaintiffs’ attorneys’ fees and undertake certain business and governance practices. The state court granted final approval of the settlement on January 15, 2020, and a notice of appeal has been filed. These and other issues related to the origination, servicing, and collection of consumer automobile loans, including related insurance products, have also subjected the Company to formal or informal inquiries, investigations, or examinations from federal and state government agencies. In December 2018, the Company entered into an agreement with all 50 state Attorneys General and the District of Columbia to resolve an investigation into the Company’s retail sales practices, CPI and GAP, and mortgage interest rate lock matters, pursuant to which the Company paid $575 million . CONSENT ORDER DISCLOSURE LITIGATION Wells Fargo shareholders have brought securities fraud class actions in the United States District Courts for the Northern District of California and the Southern District of New York alleging that the Company made false or misleading statements regarding its efforts to comply with the February 2018 consent order with the FRB and the April 2018 consent orders with the CFPB and OCC. CONSUMER DEPOSIT ACCOUNT RELATED REGULATORY INVESTIGATION The CFPB is conducting an investigation into whether customers were unduly harmed by the Company’s historical practices associated with the freezing (and, in many cases, closing) of consumer deposit accounts after the Company detected suspected fraudulent activity (by third parties or account holders) that affected those accounts. CORONAVIRUS AID, RELIEF, AND ECONOMIC SECURITY ACT/PAYCHECK PROTECTION PROGRAM Plaintiffs have filed putative class actions in various federal courts against the Company. The actions seek damages and injunctive relief related to the Company’s offering of Paycheck Protection Program (PPP) loans under the Coronavirus Aid, Relief, and Economic Security Act, as well as claims for fees by purported agents who allegedly assisted customers with preparing PPP loan applications submitted to the Company. The Company has also received formal and informal inquiries from federal and state governmental agencies regarding its offering of PPP loans. FIDUCIARY AND CUSTODY ACCOUNT FEE CALCULATIONS Federal government agencies are conducting formal or informal inquiries, investigations, or examinations regarding fee calculations within certain fiduciary and custody accounts in the Company’s investment and fiduciary services business, which is part of the wealth management business within the Wealth and Investment Management (WIM) operating segment. The Company has determined that there have been instances of incorrect fees being applied to certain assets and accounts, resulting in both overcharges and undercharges to customers. FOREIGN EXCHANGE BUSINESS The United States Department of Justice (Department of Justice) is investigating certain activities in the Company’s foreign exchange business, including whether customers may have received pricing inconsistent with commitments made to those customers. Previous investigations by other federal government agencies have been resolved. INTERCHANGE LITIGATION Plaintiffs representing a putative class of merchants have filed putative class actions, and individual merchants have filed individual actions, against Wells Fargo Bank, N.A., Wells Fargo & Company, Wachovia Bank, N.A., and Wachovia Corporation regarding the interchange fees associated with Visa and MasterCard payment card transactions. Visa, MasterCard, and several other banks and bank holding companies are also named as defendants in these actions. These actions have been consolidated in the United States District Court for the Eastern District of New York. The amended and consolidated complaint asserts claims against defendants based on alleged violations of federal and state antitrust laws and seeks damages, as well as injunctive relief. Plaintiff merchants allege that Visa, MasterCard, and payment card issuing banks unlawfully colluded to set interchange rates. Plaintiffs also allege that enforcement of certain Visa and MasterCard rules and alleged tying and bundling of services offered to merchants are anticompetitive. Wells Fargo and Wachovia, along with other defendants and entities, are parties to Loss and Judgment Sharing Agreements, which provide that they, along with other entities, will share, based on a formula, in any losses from the Interchange Litigation. On July 13, 2012, Visa, MasterCard, and the financial institution defendants, including Wells Fargo, signed a memorandum of understanding with plaintiff merchants to resolve the consolidated class action and reached a separate settlement in principle of the consolidated individual actions. The settlement payments to be made by all defendants in the consolidated class and individual actions totaled approximately $6.6 billion before reductions applicable to certain merchants opting out of the settlement. The class settlement also provided for the distribution to class merchants of 10 basis points of default interchange across all credit rate categories for a period of eight consecutive months. The district court granted final approval of the settlement, which was appealed to the United States Court of Appeals for the Second Circuit by settlement objector merchants. Other merchants opted out of the settlement and are pursuing several individual actions. On June 30, 2016, the Second Circuit vacated the settlement agreement and reversed and remanded the consolidated action to the United States District Court for the Eastern District of New York for further proceedings. On November 23, 2016, prior class counsel filed a petition to the United States Supreme Court, seeking review of the reversal of the settlement by the Second Circuit, and the Supreme Court denied the petition on March 27, 2017. On November 30, 2016, the district court appointed lead class counsel for a damages class and an equitable relief class. The parties have entered into a settlement agreement to resolve the money damages class claims pursuant to which defendants will pay a total of approximately $6.2 billion , which includes approximately $5.3 billion of funds remaining from the 2012 settlement and $900 million in additional funding. The Company’s allocated responsibility for the additional funding is approximately $94.5 million . The court granted final approval of the settlement on December 13, 2019, which was appealed to the United States Court of Appeals for the Second Circuit by settlement objector merchants. Several of the opt-out and direct action litigations have been settled while others remain pending. Discovery is proceeding in the opt-out litigations and the equitable relief class case. LOW INCOME HOUSING TAX CREDITS Federal government agencies have undertaken formal or informal inquiries or investigations regarding the manner in which the Company purchased, and negotiated the purchase of, certain federal low income housing tax credits in connection with the financing of low income housing developments. MOBILE DEPOSIT PATENT LITIGATION The Company is a defendant in two separate cases brought by United Services Automobile Association (USAA) in the United States District Court for the Eastern District of Texas alleging claims of patent infringement regarding mobile deposit capture technology patents held by USAA. Trial in the first case commenced on October 30, 2019, and resulted in a $200 million verdict against the Company. Trial in the second case commenced on January 6, 2020, and resulted in a $102.7 million verdict against the Company. The Company has filed post-trial motions to, among other things, vacate the verdicts, and USAA has filed post-trial motions seeking future royalty payments and damages for willful infringement. MORTGAGE LOAN MODIFICATION LITIGATION Plaintiffs representing a putative class of mortgage borrowers have filed separate putative class actions, Hernandez v. Wells Fargo, et al. , Coordes v. Wells Fargo, et al. , Ryder v. Wells Fargo , Liguori v. Wells Fargo , and Dore v. Wells Fargo , against Wells Fargo Bank, N.A., in the United States District Court for the Northern District of California, the United States District Court for the District of Washington, the United States District Court for the Southern District of Ohio, the United States District Court for the Southern District of New York, and the United States District Court for the Western District of Pennsylvania, respectively. Plaintiffs allege that Wells Fargo improperly denied mortgage loan modifications or repayment plans to customers in the foreclosure process due to the overstatement of foreclosure attorneys’ fees that were included for purposes of determining whether a customer in the foreclosure process qualified for a mortgage loan modification or repayment plan. The district court in the Hernandez case certified a nationwide breach of contract class for foreclosed borrowers and denied certification on claims pertaining to other impacted borrowers. In March 2020, the Company entered into an agreement pursuant to which the Company will pay $18.5 million to resolve the claims of the certified class in the Hernandez case. MORTGAGE-RELATED REGULATORY INVESTIGATIONS Federal and state government agencies, including the Department of Justice, have been investigating or examining certain mortgage related activities of Wells Fargo and predecessor institutions. Wells Fargo, for itself and for predecessor institutions, has responded, or continues to respond, to requests from these agencies seeking information regarding the origination, underwriting, and securitization of residential mortgages, including sub-prime mortgages. These agencies have advanced theories of purported liability with respect to certain of these activities. An agreement, pursuant to which the Company paid $2.09 billion , was reached in August 2018 to resolve the Department of Justice investigation, which related to certain 2005-2007 residential mortgage-backed securities activities. In addition, the Company reached an agreement with the Attorney General of the State of Illinois in November 2018 pursuant to which the Company paid $17 million in restitution to certain Illinois state pension funds and reached an agreement with the Attorney General of the State of Maryland in June 2020 pursuant to which the Company agreed to pay $20 million in restitution, in each case to resolve claims relating to certain residential mortgage-backed securities activities. Other financial institutions have entered into similar settlements with these agencies, the nature of which related to the specific activities of those financial institutions, including the imposition of significant financial penalties and remedial actions. NOMURA/NATIXIS MORTGAGE-RELATED LITIGATION In August 2014 and August 2015, Nomura Credit & Capital Inc. (Nomura) and Natixis Real Estate Holdings, LLC (Natixis) filed a total of seven third-party complaints against Wells Fargo Bank, N.A., in New York state court. In the underlying first-party actions, Nomura and Natixis have been sued for alleged breaches of representations and warranties made in connection with residential mortgage-backed securities sponsored by them. In the third-party actions, Nomura and Natixis allege that Wells Fargo, as master servicer, primary servicer or securities administrator, failed to notify Nomura and Natixis of their own breaches, failed to properly oversee the primary servicers, and failed to adhere to accepted servicing practices. Natixis additionally alleges that Wells Fargo failed to perform default oversight duties. Wells Fargo has asserted counterclaims alleging that Nomura and Natixis failed to provide Wells Fargo notice of their representation and warranty breaches. OFAC RELATED INVESTIGATION The Company has self-identified an issue whereby certain foreign banks utilized a Wells Fargo software-based solution to conduct import/export trade-related financing transactions with countries and entities prohibited by the Office of Foreign Assets Control (OFAC) of the United States Department of the Treasury. We do not believe any funds related to these transactions flowed through accounts at Wells Fargo as a result of the aforementioned conduct. The Company has made voluntary self-disclosures to OFAC and is cooperating with an inquiry from the Department of Justice. ORDER OF POSTING LITIGATION Plaintiffs filed a series of putative class actions against Wachovia Bank, N.A., and Wells Fargo Bank, N.A., as well as many other banks, challenging the “high to low” order in which the banks post debit card transactions to consumer deposit accounts. Most of these actions were consolidated in multi-district litigation proceedings (MDL proceedings) in the United States District Court for the Southern District of Florida. The court in the MDL proceedings has certified a class of putative plaintiffs, and Wells Fargo moved to compel arbitration of the claims of unnamed class members. The court denied the motions to compel arbitration in October 2016, and Wells Fargo appealed this decision to the United States Court of Appeals for the Eleventh Circuit. In May 2018, the Eleventh Circuit ruled in Wells Fargo’s favor and found that Wells Fargo had not waived its arbitration rights and remanded the case to the district court for further proceedings. On September 26, 2019, the district court entered an order granting Wells Fargo’s motion and dismissed the claims of unnamed class members in favor of arbitration. Plaintiffs appealed this decision to the United States Court of Appeals for the Eleventh Circuit. RETAIL SALES PRACTICES MATTERS A number of bodies or entities, including (a) federal, state, and local government agencies, including the Department of Justice, the United States Securities and Exchange Commission (SEC), and the United States Department of Labor, (b) state attorneys general, including the New York Attorney General, and (c) Congressional committees, have undertaken formal or informal inquiries, investigations, or examinations arising out of certain retail sales practices of the Company that were the subject of settlements with the CFPB, the OCC, and the Office of the Los Angeles City Attorney announced by the Company on September 8, 2016. These matters are at varying stages. The Company has responded, and continues to respond, to requests from certain of the foregoing. In October 2018, the Company entered into an agreement to resolve the New York Attorney General’s investigation pursuant to which the Company paid $65 million to the State of New York. In December 2018, the Company entered into an agreement with all 50 state Attorneys General and the District of Columbia to resolve an investigation into the Company’s retail sales practices, CPI and GAP, and mortgage interest rate lock matters, pursuant to which the Company paid $575 million . On February 21, 2020 , the Company entered into an agreement with the Department of Justice to resolve the Department of Justice’s criminal investigation into the Company’s retail sales practices, as well as a separate agreement to resolve the Department of Justice’s civil investigation. As part of the Department of Justice criminal settlement, no charges will be filed against the Company provided the Company abides by all the terms of the agreement. The Department of Justice criminal settlement also includes the Company’s agreement that the facts set forth in the settlement document constitute sufficient facts for the finding of criminal violations of statutes regarding bank records and personal information. On February 21, 2020 , the Company also entered into an order to resolve the SEC’s investigation arising out of the Company’s retail sales practices. The SEC order contains a finding, to which the Company consented, that the facts set forth include violations of Section 10(b) of the Securities Exchange Act of 1934 and Rule 10b-5 thereunder. As part of the resolution of the Department of Justice and SEC investigations, the Company has agreed to make payments totaling $3.0 billion . In addition, as part of the settlements and included in the $3.0 billion amount, the Company has agreed to the creation of a $500 million Fair Fund for the benefit of investors who were harmed by the conduct covered in the SEC settlement. In addition, a number of lawsuits have been filed by non-governmental parties seeking damages or other remedies related to these retail sales practices. First, various class plaintiffs, purporting to represent consumers who allege that they received products or services without their authorization or consent, have brought separate putative class actions against the Company in the United States District Court for the Northern District of California and various other jurisdictions. On June 14, 2018, the district court granted final approval of a settlement entered into by the Company in the first-filed action, Jabbari v. Wells Fargo Bank, N.A ., pursuant to which the Company will pay $142 million to resolve claims regarding certain products or services provided without authorization or consent for the time period May 1, 2002 to April 20, 2017. On July 20, 2020, the United States Court of Appeals for the Ninth Circuit affirmed the district court's order granting final approval of the settlement. Second, the Company was subject to a consolidated securities fraud class action alleging certain misstatements and omissions in the Company’s disclosures related to sales practices matters. The Company entered into a settlement agreement to resolve this matter pursuant to which the Company paid $480 million . Third, Wells Fargo shareholders have brought numerous shareholder derivative lawsuits asserting breach of fiduciary duty claims against, among others, current and former directors and officers for their alleged involvement with and failure to detect and prevent sales practices issues. These actions are currently pending in the United States District Court for the Northern District of California and California state court as consolidated or coordinated proceedings. The parties have entered into settlement agreements to resolve the shareholder derivative lawsuits pursuant to which insurance carriers will pay the Company approximately $240 million for alleged damage to the Company, and the Company will pay plaintiffs’ attorneys’ fees. The federal court granted final approval of the settlement for its action on April 7, 2020. The state court granted final approval of the settlement for its action on January 15, 2020. Fourth, a purported Employee Retirement Income Security Act (ERISA) class action was filed in the United States District Court for the District of Minnesota on behalf of 401(k) plan participants. The district court dismissed the action, and on July 27, 2020, the United States Court of Appeals for the Eighth Circuit affirmed the dismissal. RMBS TRUSTEE LITIGATION In November 2014, a group of institutional investors (Institutional Investor Plaintiffs), including funds affiliated with BlackRock, Inc., filed a putative class action in the United States District Court for the Southern District of New York against Wells Fargo Bank, N.A., alleging claims against the Company in its capacity as trustee for a number of residential mortgage-backed securities (RMBS) trusts (Federal Court Complaint). Similar complaints have been filed against other trustees in various courts, including in the Southern District of New York, in New York state court, and in other states, by RMBS investors. The Federal Court Complaint alleged that Wells Fargo Bank, N.A., as trustee, caused losses to investors and asserted causes of action based upon, among other things, the trustee’s alleged failure to notify and enforce repurchase obligations of mortgage loan sellers for purported breaches of representations and warranties, notify investors of alleged events of default, and abide by appropriate standards of care following alleged events of default. Plaintiffs sought money damages in an unspecified amount, reimbursement of expenses, and equitable relief. In December 2014 and December 2015, certain other investors filed additional complaints alleging similar claims against Wells Fargo Bank, N.A., in the Southern District of New York (Related Federal Cases). In January 2016, the Southern District of New York entered an order in connection with the Federal Court Complaint dismissing claims related to certain of the trusts at issue (Dismissed Trusts). The Company’s subsequent motion to dismiss the Federal Court Complaint and the complaints for the Related Federal Cases was granted in part and denied in part in March 2017. In May 2017, the Company filed third-party complaints against certain investment advisors affiliated with the Institutional Investor Plaintiffs seeking contribution with respect to claims alleged in the Federal Court Complaint (Third-Party Claims). In December 2016, the Institutional Investor Plaintiffs filed a new putative class action complaint in New York state court in respect of 261 RMBS trusts, including the Dismissed Trusts, for which Wells Fargo Bank, N.A., serves or served as trustee (State Court Action). A complaint raising similar allegations to those in the Federal Court Complaint was filed in May 2016 in New York state court by IKB International and IKB Deutsche Industriebank (IKB Action). In July 2017, certain of the plaintiffs from the State Court Action filed a civil complaint relating to Wells Fargo Bank, N.A.’s setting aside reserves for legal fees and expenses in connection with the liquidation of eleven RMBS trusts at issue in the State Court Action (Declaratory Judgment Action). The complaint sought, among other relief, declarations that the Company is not entitled to indemnification, the advancement of funds, or the taking of reserves from trust funds for legal fees and expenses it incurs in defending the claims in the State Court Action. In May 2019, the New York state court approved a settlement agreement among the Institutional Investor Plaintiffs and the Company pursuant to which, among other terms, the Company paid $43 million to resolve the Federal Court Complaint and the State Court Action. The settlement also resolved the Third Party Claims and the Declaratory Judgment Action. The settlement did not affect the Related Federal Cases or the IKB Action, which remain pending. SEMINOLE TRIBE TRUSTEE LITIGATION The Seminole Tribe of Florida filed a complaint in Florida state court alleging that Wells Fargo, as trustee, charged excess fees in connection with the administration of a minor’s trust and failed to invest the assets of the trust prudently. The complaint was later amended to include three individual current and former beneficiaries as plaintiffs and to remove the Tribe as a party to the case. In December 2016, the Company filed a motion to dismiss the amended complaint on the grounds that the Tribe is a necessary party and that the individual beneficiaries lack standing to bring claims. The motion was denied in June 2018. The case is pending trial. WHOLESALE BANKING CONSENT ORDER INVESTIGATION On November 19, 2015, the Company entered into a consent order with the OCC, pursuant to which the Wholesale Banking group was required to implement customer due diligence standards that include collection of current beneficial ownership information for certain business customers. The Company is responding to inquiries from various federal government agencies regarding potentially inappropriate conduct in connection with the collection of beneficial ownership information. OUTLOOK As described above, the Company establishes accruals for legal actions when potential losses associated with the actions become probable and the costs can be reasonably estimated. The high end of the range of reasonably possible potential losses in excess of the Company’s accrual for probable and estimable losses was approximately $2.3 billion as of June 30, 2020 . The outcomes of legal actions are unpredictable and subject to significant uncertainties, and it is inherently difficult to determine whether any loss is probable or even possible. It is also inherently difficult to estimate the amount of any loss and there may be matters for which a loss is probable or reasonably possible but not currently estimable. Accordingly, actual losses may be in excess of the established accrual or the range of reasonably possible loss. Wells Fargo is unable to determine whether the ultimate resolution of the retail sales practices matters will have a material adverse effect on its consolidated financial condition. Based on information currently available, advice of counsel, available insurance coverage, and established reserves, Wells Fargo believes that the eventual outcome of other actions against Wells Fargo and/or its subsidiaries will not, individually or in the aggregate, have a material adverse effect on Wells Fargo’s consolidated financial condition. However, it is possible that the ultimate resolution of a matter, if unfavorable, may be material to Wells Fargo’s results of operations for any particular period.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives	Note 15: Derivatives We use derivatives to manage exposure to market risk, including interest rate risk, credit risk and foreign currency risk, and to assist customers with their risk management objectives. We designate certain derivatives as hedging instruments in qualifying hedge accounting relationships (fair value or cash flow hedges). Our remaining derivatives consist of economic hedges that do not qualify for hedge accounting, and derivatives held for customer accommodation trading or other purposes. For more information on our derivative activities, see Note 18 (Derivatives) in our 2019 Form 10-K. Table 15.1 presents the total notional or contractual amounts and fair values for our derivatives. Derivative transactions can be measured in terms of the notional amount, but this amount is not recorded on the balance sheet and is not, when viewed in isolation, a meaningful measure of the risk profile of the instruments. The notional amount is generally not exchanged but is used only as the basis on which interest and other payments are determined. Table 15.1: Notional or Contractual Amounts and Fair Values of Derivatives June 30, 2020 December 31, 2019 Notional or contractual amount Fair value Notional or contractual amount Fair value (in millions) Derivative assets Derivative liabilities Derivative Derivative Derivatives designated as hedging instruments Interest rate contracts $ 192,835 3,701 2,035 182,789 2,595 1,237 Foreign exchange contracts 34,459 281 1,220 32,386 341 1,170 Total derivatives designated as qualifying hedging instruments 3,982 3,255 2,936 2,407 Derivatives not designated as hedging instruments Economic hedges: Interest rate contracts 313,604 556 374 235,810 207 160 Equity contracts 22,616 1,294 100 19,263 1,126 224 Foreign exchange contracts 52,349 1,062 196 26,595 118 286 Credit contracts – protection purchased 99 35 — 1,400 27 — Subtotal 2,947 670 1,478 670 Customer accommodation trading and other derivatives: Interest rate contracts 11,254,860 44,355 34,055 11,117,542 21,245 17,969 Commodity contracts 77,608 2,039 3,741 79,737 1,421 1,770 Equity contracts 303,271 9,375 11,986 272,145 7,410 10,240 Foreign exchange contracts 302,847 5,088 6,043 364,469 4,755 4,791 Credit contracts – protection sold 15,513 10 58 12,215 12 65 Credit contracts – protection purchased 25,695 85 15 24,030 69 18 Subtotal 60,952 55,898 34,912 34,853 Total derivatives not designated as hedging instruments 63,899 56,568 36,390 35,523 Total derivatives before netting 67,881 59,823 39,326 37,930 Netting (45,105 ) (48,455 ) (25,123 ) (28,851 ) Total $ 22,776 11,368 14,203 9,079 Table 15.2 provides information on the gross fair values of derivative assets and liabilities, the balance sheet netting adjustments and the resulting net fair value amount recorded on our balance sheet, as well as the non-cash collateral associated with such arrangements. We execute substantially all of our derivative transactions under master netting arrangements and reflect all derivative balances and related cash collateral subject to enforceable master netting arrangements on a net basis within the balance sheet. The “Gross amounts recognized” column in the following table includes $59.6 billion and $54.7 billion of gross derivative assets and liabilities, respectively, at June 30, 2020 , and $33.7 billion and $33.5 billion , respectively, at December 31, 2019 , with counterparties subject to enforceable master netting arrangements that are eligible for balance sheet netting adjustments. The majority of these amounts are interest rate contracts executed in over-the-counter (OTC) markets. The remaining gross derivative assets and liabilities of $8.3 billion and $5.1 billion , respectively, at June 30, 2020 , and $5.6 billion and $4.4 billion , respectively, at December 31, 2019 , include those with counterparties subject to master netting arrangements for which we have not assessed the enforceability because they are with counterparties where we do not currently have positions to offset, those subject to master netting arrangements where we have not been able to confirm the enforceability and those not subject to master netting arrangements. As such, we do not net derivative balances or collateral within the balance sheet for these counterparties. Cash collateral receivables and payables that have not been offset against our derivatives were $1.2 billion and $1.4 billion , respectively, at June 30, 2020 , and $6.3 billion and $1.4 billion , respectively, at December 31, 2019 . We determine the balance sheet netting adjustments based on the terms specified within each master netting arrangement. We disclose the balance sheet netting amounts within the column titled “Gross amounts offset in consolidated balance sheet.” Balance sheet netting adjustments are determined at the counterparty level for which there may be multiple contract types. For disclosure purposes, we allocate these netting adjustments to the contract type for each counterparty proportionally based upon the “Gross amounts recognized” by counterparty. As a result, the net amounts disclosed by contract type may not represent the actual exposure upon settlement of the contracts. We do not net non-cash collateral that we receive and pledge on the balance sheet. For disclosure purposes, we present the fair value of this non-cash collateral in the column titled “Gross amounts not offset in consolidated balance sheet (Disclosure-only netting)” within the table. We determine and allocate the Disclosure-only netting amounts in the same manner as balance sheet netting amounts. The “Net amounts” column within Table 15.2 represents the aggregate of our net exposure to each counterparty after considering the balance sheet and Disclosure-only netting adjustments. We manage derivative exposure by monitoring the credit risk associated with each counterparty using counterparty specific credit risk limits, using master netting arrangements and obtaining collateral. Derivative contracts executed in OTC markets include bilateral contractual arrangements that are not cleared through a central clearing organization but are typically subject to master netting arrangements. Other derivative contracts that are settled through a central clearing organization whether OTC or exchange-traded, are excluded from that percentage. In addition to the netting amounts included in the table, we also have balance sheet netting related to resale and repurchase agreements that are disclosed within Note 13 (Guarantees, Pledged Assets and Collateral, and Other Commitments).

Counterparty valuation adjustments related to derivative assets were $600 million and $231 million and debit valuation adjustments related to derivative liabilities were $229 million and $100 million at June 30, 2020 , and December 31, 2019 , respectively. Cash collateral totaled $7.3 billion and $11.0 billion , netted against derivative assets and liabilities, respectively, at June 30, 2020 , and $2.9 billion and $6.8 billion , respectively, at December 31, 2019 . Fair Value and Cash Flow Hedges For fair value hedges, we use interest rate swaps to convert certain of our fixed-rate long-term debt and time certificates of deposit to floating rates to hedge our exposure to interest rate risk. We also enter into cross-currency swaps, cross-currency interest rate swaps and forward contracts to hedge our exposure to foreign currency risk and interest rate risk associated with the issuance of non-U.S. dollar denominated long-term debt. In addition, we use interest rate swaps, cross-currency swaps, cross-currency interest rate swaps and forward contracts to hedge against changes in fair value of certain investments in available-for-sale debt securities due to changes in interest rates, foreign currency rates, or both. We also use interest rate swaps to hedge against changes in fair value for certain mortgage loans held for sale. For certain fair value hedges of foreign currency risk, changes in fair value of cross-currency swaps attributable to changes in cross-currency basis spreads are excluded from the assessment of hedge effectiveness and recorded in other comprehensive income. See Note 26 (Other Comprehensive Income) for the amounts recognized in other comprehensive income. For cash flow hedges, we use interest rate swaps to hedge the variability in interest payments received on certain floating-rate commercial loans and paid on certain floating-rate debt due to changes in the contractually specified interest rate. We also use cross-currency swaps to hedge variability in interest payments on fixed-rate foreign currency-denominated long-term debt due to changes in foreign exchange rates. We estimate $203 million pre-tax of deferred net losses related to cash flow hedges in OCI at June 30, 2020 , will be reclassified into net interest income during the next twelve months. The deferred losses expected to be reclassified into net interest income are predominantly related to discontinued hedges of floating rate loans. For cash flow hedges as of June 30, 2020 , we are hedging our foreign currency exposure to the variability of future cash flows for all forecasted transactions for a maximum of 10 years . For more information on our accounting hedges, see Note 1 (Summary of Significant Accounting Policies) and Note 18 (Derivatives) in our 2019 Form 10-K.

(3) The balance includes $548 million and $143 million of debt securities and long-term debt cumulative basis adjustments, respectively, as of June 30, 2020 , and $790 million and $109 million of debt securities and long-term debt cumulative basis adjustments, respectively, as of December 31, 2019 , on terminated hedges whereby the hedged items have subsequently been re-designated into existing hedges. (4) Represents the full carrying amount of the hedged asset or liability item as of the balance sheet date, except for circumstances in which only a portion of the asset or liability was designated as the hedged item in which case only the portion designated is presented. (5) Carrying amount represents the amortized cost. Derivatives Not Designated as Hedging Instruments Derivatives not designated as hedging instruments include economic hedges and derivatives entered into for customer accommodation trading purposes. We use economic hedge derivatives to manage our exposure to interest rate risk, equity price risk, foreign currency risk, and credit risk. We also use economic hedge derivatives to mitigate the periodic earnings volatility caused by mismatches between the changes in fair value of the hedged item and hedging instrument recognized on our fair value accounting hedges. In second quarter 2020, we entered into arrangements to transition the economic hedges of our deferred compensation plan liabilities from equity securities to derivative instruments. Changes in the fair values of derivatives used to economically hedge the deferred compensation plan are reported in personnel expense. For more information on economic hedges and other derivatives, see Note 18 (Derivatives) to Financial Statements in our 2019 Form 10-K.

The corresponding amounts for the second quarter and first half of 2019 are comprised of gains of $1.2 billion and $2.1 billion offset by gains (losses) of $(283) million and $(434) million , respectively. Credit Derivatives Credit derivative contracts are arrangements whose value is derived from the transfer of credit risk of a reference asset or entity from one party (the purchaser of credit protection) to another party (the seller of credit protection). We use credit derivatives to assist customers with their risk management objectives. We may also use credit derivatives in structured product transactions or liquidity agreements written to special purpose vehicles. The maximum exposure of sold credit derivatives is managed through posted collateral, purchased credit derivatives and similar products in order to achieve our desired credit risk profile. This credit risk management provides an ability to recover a significant portion of any amounts that would be paid under the sold credit derivatives. We would be required to perform under sold credit derivatives in the event of default by the referenced obligors. Events of default include events such as bankruptcy, capital restructuring or lack of principal and/or interest payment. In certain cases, other triggers may exist, such as the credit downgrade of the referenced obligors or the inability of the special purpose vehicle for which we have provided liquidity to obtain funding. Table 15.7 provides details of sold and purchased credit derivatives.

We believe this hypothetical circumstance to be an extremely remote possibility and accordingly, this required disclosure is not an indication of expected loss. The amounts under non-investment grade represent the notional amounts of those credit derivatives on which we have a higher risk of being required to perform under the terms of the credit derivative and are a function of the underlying assets. We consider the risk of performance to be high if the underlying assets under the credit derivative have an external rating that is below investment grade or an internal credit default grade that is equivalent thereto. We believe the net protection sold, which is representative of the net notional amount of protection sold and purchased with identical underlyings, in combination with other protection purchased, is more representative of our exposure to loss than either non-investment grade or protection sold. Other protection purchased represents additional protection, which may offset the exposure to loss for protection sold, that was not purchased with an identical underlying of the protection sold. Credit-Risk Contingent Features Certain of our derivative contracts contain provisions whereby if the credit rating of our debt were to be downgraded by certain major credit rating agencies, the counterparty could demand additional collateral or require termination or replacement of derivative instruments in a net liability position. Table 15.8 illustrates our exposure to such derivatives with credit-risk contingent features, collateral we have posted, and the additional collateral we would be required to post if the credit rating of our debt was downgraded below investment grade.

Fair Value Disclosures [Abstract]
Fair Values of Assets and Liabilities	Note 16: Fair Values of Assets and Liabilities We use fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. Assets and liabilities recorded at fair value on a recurring basis are presented in Table 16.2 in this Note. From time to time, we may be required to record fair value adjustments on a nonrecurring basis. These nonrecurring fair value adjustments typically involve application of LOCOM accounting, write-downs of individual assets or application of the measurement alternative for nonmarketable equity securities. Assets recorded on a nonrecurring basis are presented in Table 16.1 3 in this Note. Table 16.19 includes estimates of fair value for financial instruments that are not recorded at fair value. See Note 1 (Summary of Significant Accounting Policies) in our 2019 Form 10-K for discussion of how we determine fair value. For descriptions of the valuation methodologies we use for assets and liabilities recorded at fair value on a recurring or nonrecurring basis and for estimating fair value for financial instruments that are not recorded at fair value, see Note 19 (Fair Values of Assets and Liabilities) in our 2019 Form 10-K. FAIR VALUE HIERARCHY We classify our assets and liabilities measured at fair value as either Level 1, Level 2 or Level 3 in the fair value hierarchy. The highest priority (Level 1) is assigned to valuations based on unadjusted quoted prices in active markets and the lowest priority (Level 3) is assigned to valuations based on significant unobservable inputs. See Note 1 (Summary of Significant Accounting Policies) in our 2019 Form 10-K for a detailed description of the fair value hierarchy. In the determination of the classification of financial instruments in Level 2 or Level 3 of the fair value hierarchy, we consider all available information, including observable market data, indications of market liquidity and orderliness, and our understanding of the valuation techniques and significant inputs used. For securities in inactive markets, we use a predetermined percentage to evaluate the impact of fair value adjustments derived from weighting both external and internal indications of value to determine if the instrument is classified as Level 2 or Level 3. Otherwise, the classification of Level 2 or Level 3 is based upon the specific facts and circumstances of each instrument or instrument category and judgments are made regarding the significance of the Level 3 inputs to the instruments’ fair value measurement in its entirety. If Level 3 inputs are considered significant, the instrument is classified as Level 3. We do not classify equity securities in the fair value hierarchy if we use the non-published net asset value (NAV) per share (or its equivalent) that has been communicated to us as an investor as a practical expedient to measure fair value. We generally use NAV per share as the fair value measurement for certain nonmarketable equity fund investments. Marketable equity securities with published NAVs are classified in the fair value hierarchy. Fair Value Measurements from Vendors For certain assets and liabilities, we obtain fair value measurements from vendors and we record the fair value in our financial statements. For additional information, see Note 19 (Fair Values of Assets and Liabilities) in our 2019 Form 10-K. Table 16.1 presents fair value measurements obtained from third-party pricing services classified within the fair value hierarchy. Fair value measurements obtained from brokers and fair value measurements obtained from third-party pricing services that we have adjusted using internal models or non-vendor data to determine the fair value are excluded from Table 16.1 . The unadjusted fair value measurements obtained from brokers for available-for-sale debt securities were $19 million in Level 2 assets and $123 million in Level 3 assets at June 30, 2020 , and $45 million and $126 million at December 31, 2019 , respectively.

Changes in Fair Value Levels We monitor the availability of observable market data to assess the appropriate classification of financial instruments within the fair value hierarchy and transfer between Level 1, Level 2, and Level 3 accordingly. Observable market data includes but is not limited to quoted prices and market transactions. Changes in economic conditions or market liquidity generally will drive changes in availability of observable market data. Changes in availability of observable market data, which also may result in changing the valuation technique used, are generally the cause of transfers between Level 1, Level 2, and Level 3. The amounts reported as transfers represent the fair value as of the beginning of the quarter in which the transfer occurred. The changes in Level 3 assets and liabilities measured at fair value on a recurring basis for the quarter ended June 30, 2020 , are presented in Table 16.3 Table 16.3: Changes in Level 3 Fair Value Assets and Liabilities on a Recurring Basis – Quarter ended June 30, 2020 Total net gains (losses) included in Purchases, sales, issuances and settlements, net (1) Net unrealized gains (losses) related to assets and liabilities held at period end included in (in millions) Balance, beginning of period Net income Other compre- hensive income Transfers into Level 3 (2) Transfers out of Level 3 (3) Balance, end of period Net income (4) Other compre-hensive income Quarter ended June 30, 2020 Trading debt securities: Securities of U.S. states and political subdivisions $ — — — — — — — — — Collateralized loan obligations 154 — — 4 (5 ) (25 ) 128 (2 ) — Corporate debt securities 34 (7 ) — 1 — (5 ) 23 1 — Mortgage-backed securities 177 35 — (148 ) 4 (19 ) 49 12 — Other 24 5 — (22 ) 16 — 23 3 — Total trading debt securities 389 33 — (165 ) 15 (49 ) 223 14 (5) — Available-for-sale debt securities: Securities of U.S. states and political subdivisions 351 1 2 (23 ) 35 (15 ) 351 — — Mortgage-backed securities: Residential 31 5 — (25 ) — (11 ) — — — Commercial 154 (2 ) (1 ) (1 ) 31 (120 ) 61 (2 ) (1 ) Total mortgage-backed securities 185 3 (1 ) (26 ) 31 (131 ) 61 (2 ) (1 ) Corporate debt securities 1,130 (2 ) 43 (46 ) — (74 ) 1,051 (2 ) 42 Collateralized loan obligations 50 — (1 ) — 10 (50 ) 9 — — Other 696 3 (27 ) (28 ) 9 (27 ) 626 (1 ) (28 ) Total available-for-sale debt securities 2,412 5 16 (123 ) 85 (297 ) 2,098 (5 ) (6) 13 Mortgage loans held for sale 3,157 (37 ) — (251 ) 80 (2,198 ) 751 (27 ) (7) — Loans held for sale 19 (4 ) — (7 ) — (1 ) 7 (5 ) (5) — Loans 160 (2 ) — (6 ) — — 152 (4 ) (7) — Mortgage servicing rights (residential)(8) 8,126 (1,768 ) — 461 — — 6,819 (1,131 ) (7) — Net derivative assets and liabilities: Interest rate contracts 685 460 — (622 ) — — 523 291 — Commodity contracts (44 ) 15 — 12 18 — 1 45 — Equity contracts 217 (277 ) — 79 — 1 20 (387 ) — Foreign exchange contracts (6 ) (12 ) — 2 — — (16 ) 2 — Credit contracts 47 4 — (1 ) — — 50 — — Total derivative contracts 899 190 — (530 ) 18 1 578 (49 ) (9) — Equity securities: Marketable 3 — — — — (3 ) — — — Nonmarketable 6,751 1,414 — — — — 8,165 1,414 — Total equity securities 6,754 1,414 — — — (3 ) 8,165 1,414 (10) — Short sale liabilities — — — (3 ) — — (3 ) — (5) — Other liabilities (2 ) — — — — — (2 ) — (7) — (1) See Table 16.4 for detail.

We provide services to customers which have related performance obligations that we complete to recognize revenue. Our revenues are generally recognized either immediately upon the completion of our service or over time as we perform services. Any services performed over time generally require that we render services each period and therefore we measure our progress in completing these services based upon the passage of time.

Account charges include fees for periodic account maintenance activities and event-driven services such as stop payment fees. Our obligation for event-driven services is satisfied at the time of the event when the service is delivered, while our obligation for maintenance services is satisfied over the course of each month. Our obligation for overdraft services is satisfied at the time of the overdraft. Table 18.2 presents our service charges on deposit accounts by operating segment.

The remaining revenues include trailing commissions which are earned for selling shares to investors. Our obligation associated with earning trailing commissions is satisfied at the time shares are sold. However, these fees are received and recognized over time during the period the customer owns the shares and we remain the broker of record. The amount of trailing commissions is variable based on the length of time the customer holds the shares and on changes in the value of the underlying assets. Transactional revenues are earned for executing transactions at the client’s direction. Our obligation is generally satisfied upon the execution of the transaction and the fees are based on the size and number of transactions executed. Other revenues earned from other brokerage advisory services include omnibus and networking fees received from mutual fund companies in return for providing record keeping and other administrative services, and annual account maintenance fees charged to customers.

TRUST AND INVESTMENT MANAGEMENT FEES are earned for providing trust, investment management and other related services. Investment management services include managing and administering assets, including mutual funds, and institutional separate accounts. Fees for these services are generally determined based on a tiered scale relative to the market value of assets under management (AUM). In addition to AUM, we have client assets under administration (AUA) that earn various administrative fees which are generally based on the extent of the services provided to administer the account. Services with AUM and AUA-based fees are generally performed over time. Trust services include acting as a trustee or agent for corporate trust, personal trust, and agency assets. Obligations for trust services are generally satisfied over time, while obligations for activities that are transactional in nature are satisfied at the time of the transaction. Other related services include the custody and safekeeping of accounts. Our obligation for these services is generally satisfied over time.

Defined Benefit Plan [Abstract]
Employee Benefits	Note 19: Employee Benefits and Other Expenses We sponsor a frozen noncontributory qualified defined benefit retirement plan, the Wells Fargo & Company Cash Balance Plan (Cash Balance Plan), which covers eligible employees of Wells Fargo. The Cash Balance Plan was frozen on July 1, 2009, and no new benefits have accrued after that date. For additional information on our pension and postretirement plans, including plan assumptions, investment strategy and asset allocation, projected benefit payments, and valuation methodologies used for assets measured at fair value, see Note 23 (Employee Benefits and Other Expenses) in our 2019 Form 10-K. We recognize settlement losses for our Cash Balance Plan based on an assessment of whether lump sum benefit payments will, in aggregate for the year, exceed the sum of its annual service and interest cost. Settlement losses of $70 million were recognized during second quarter 2020 representing the pro rata portion of the net loss in cumulative other comprehensive income based on the percentage reduction in the Cash Balance Plan’s projected benefit obligation attributable to lump sum benefit payments during the first half of 2020 . As a result of the settlement losses, we re-measured the Cash Balance Plan obligation and plan assets as of June 30, 2020 , and used a discount rate of 2.75% based on our consistent methodology of determining our discount rate using a yield curve with maturity dates that closely match the estimated timing of the expected benefit payments. The result of the settlement losses and re-measurement increased the Cash Balance Plan liability by $674 million and decreased other comprehensive income by $604 million (pre tax) in second quarter 2020. Table 19.1 presents the components of net periodic benefit cost. Service cost is reported in personnel expense and all other components of net periodic benefit cost are reported in other noninterest expense on the consolidated statement of income.

(2) Calculated using the treasury stock method. In the second quarter and first half of 2020, diluted average common shares outstanding equaled average common shares outstanding because our securities convertible into common shares had an anti-dilutive effect. Table 20.2 presents the outstanding securities that were anti-dilutive and therefore not included in the calculation of diluted earnings per common share. Table 20.2: Outstanding Anti-Dilutive Securities Weighted-average shares Quarter ended June 30, Six months ended June 30, (in millions) 2020 2019 2020 2019 Convertible Preferred Stock, Series L (1) 25.3 25.3 25.3 25.3 Restricted share rights (2) 35.9 — 0.9 — (1) Calculated using the if-converted method. (2) Calculated using the treasury stock method. Since we had net losses attributable to common shareholders for the second quarter and first half of 2020 , all RSRs outstanding were anti-dilutive. Weighted average RSRs outstanding were 50.7 million and 54.7 million for the second quarter and first half of 2020 , respectively. Table 20.3 presents dividends declared per common share.

Operating Segments

Segment Reporting [Abstract]
Operating Segments	Note 22: Operating Segments As of June 30, 2020 , we were organized for management reporting purposes into three operating segments: Community Banking; Wholesale Banking; and Wealth and Investment Management (WIM). These segments are defined by product type and customer segment and their results are based on our management reporting process. The management reporting process is based on U.S. GAAP with specific adjustments, such as for funds transfer pricing for asset/liability management, for shared revenues and expenses, and tax-equivalent adjustments to consistently reflect income from taxable and tax-exempt sources. On February 11, 2020, we announced a new organizational structure with five principal lines of business: Consumer and Small Business Banking; Consumer Lending; Commercial Banking; Corporate and Investment Banking; and Wealth and Investment Management. This new organizational structure is intended to help drive operating, control, and business performance. In July 2020, the Company completed the transition to this new organizational structure, including finalizing leadership for these principal business lines and aligning management reporting and allocation methodologies. These changes will not impact the consolidated financial results of the Company.

Banking and Thrift [Abstract]
Regulatory and Agency Capital Requirements	Note 23: Regulatory and Agency Capital Requirements The Company and each of its subsidiary banks are subject to regulatory capital adequacy requirements promulgated by federal banking regulators. The Federal Reserve establishes capital requirements for the consolidated financial holding company, and the OCC has similar requirements for the Company’s national banks, including Wells Fargo Bank, N.A. (the Bank). Table 23.1 presents regulatory capital information for Wells Fargo & Company and the Bank in accordance with Basel III capital requirements. We must report the lower of our Common Equity Tier 1 (CET1), tier 1 and total capital ratios calculated under the Standardized Approach and under the Advanced Approach in the assessment of our capital adequacy. The Standardized Approach applies assigned risk weights to broad risk categories, while the calculation of risk-weighted assets (RWAs) under the Advanced Approach differs by requiring applicable banks to utilize a risk-sensitive methodology, which relies upon the use of internal credit models, and includes an operational risk component. The Basel III capital requirements for calculating CET1 and tier 1 capital, along with RWAs, are fully phased-in. However, the requirements for determining tier 2 and total capital are still in accordance with Transition Requirements and are scheduled to be fully phased-in by the end of 2021. Accordingly, the information presented below reflects fully phased-in CET1 capital, tier 1 capital, and RWAs, but reflects total capital still in accordance with Transition Requirements. At June 30, 2020 , the Bank and our other insured depository institutions were considered well-capitalized under the requirements of the Federal Deposit Insurance Act. The Bank is an approved seller/servicer of mortgage loans and is required to maintain minimum levels of shareholders’ equity, as specified by various agencies, including the United States Department of Housing and Urban Development, GNMA, FHLMC and FNMA. At June 30, 2020 , the Bank met these requirements. Table 23.1: Regulatory Capital Information (1) Wells Fargo & Company Wells Fargo Bank, N.A.

(1) In second quarter 2020, the Company elected to apply a modified transition provision issued by federal banking regulators in March 2020 related to the impact of CECL on regulatory capital. The rule permits certain banking organizations to exclude from regulatory capital the initial adoption impact of CECL, plus 25% of the cumulative changes in the ACL under CECL for each period until December 31, 2021, followed by a three-year phase-out of the benefits. The impact of the CECL transition provision on the regulatory capital of the Company at June 30, 2020 , was an increase in capital of $1.9 billion , reflecting a $991 million (post-tax) increase in capital recognized upon our initial adoption of CECL, offset by 25% of the $11.4 billion increase in our ACL under CECL from January 1, 2020, through June 30, 2020 . The impact of the CECL transition provision on the regulatory capital of the Bank at June 30, 2020 , was an increase in capital of $1.8 billion . (2) RWAs and capital ratios for December 31, 2019, have been revised as a result of a decrease in RWAs under the Advanced Approach due to the correction of duplicated operational loss amounts. RWAs for the Company and the Bank include an increase of $1.5 billion under both the Advanced Approach and Standardized Approach related to the impact of the CECL transition provision on the excess allowance for credit losses as of June 30, 2020 . (3) The leverage ratio consists of Tier 1 capital divided by total average assets, excluding goodwill and certain other items. (4) The supplementary leverage ratio (SLR) consists of Tier 1 capital divided by total leverage exposure. Total leverage exposure consists of total average assets, less goodwill and other permitted Tier 1 capital deductions (net of deferred tax liabilities), plus certain off-balance sheet exposures. Table 23.2 presents the minimum required regulatory capital ratios under Transition Requirements to which the Company and the Bank were subject as of June 30, 2020 , and December 31, 2019 . Table 23.2: Minimum Required Regulatory Capital Ratios – Transition Requirements (1) Wells Fargo & Company Wells Fargo Bank, N.A.

Only the 2.500% capital conservation buffer applies to the Bank at June 30, 2020 . Effective October 1, 2020, the 2.500% capital conservation buffer will be replaced under the Standardized Approach by a stress capital buffer that is calculated annually as part of the FRB's supervisory stress test and related Comprehensive Capital Analysis and Review (CCAR). (2) The Company is required to maintain a SLR of at least 5.000% (comprised of a 3.000% minimum requirement plus a supplementary leverage buffer of 2.000% ) to avoid restrictions on capital distributions and discretionary bonus payments. The Bank is required to maintain a SLR of at least 6.000% to be considered well-capitalized under applicable regulatory capital adequacy guidelines.

Significant Accounting Policies [Line Items]
Business Description and Basis of Presentation	Wells Fargo & Company is a diversified financial services company. We provide banking, trust and investments, mortgage banking, investment banking, retail banking, brokerage, and consumer and commercial finance through banking locations, the internet and other distribution channels to consumers, businesses and institutions in all 50 states, the District of Columbia, and in foreign countries. When we refer to “Wells Fargo,” “the Company,” “we,” “our” or “us,” we mean Wells Fargo & Company and Subsidiaries (consolidated). Wells Fargo & Company (the Parent) is a financial holding company and a bank holding company. We also hold a majority interest in a real estate investment trust, which has publicly traded preferred stock outstanding. Our accounting and reporting policies conform with U.S. generally accepted accounting principles (GAAP) and practices in the financial services industry. For discussion of our significant accounting policies, see Note 1 (Summary of Significant Accounting Policies) in our Annual Report on Form 10-K for the year ended December 31, 2019 ( 2019
Use of Estimates	To prepare the financial statements in conformity with GAAP, management must make estimates based on assumptions about future economic and market conditions (for example, unemployment, market liquidity, real estate prices, etc.) that affect the reported amounts of assets and liabilities at the date of the financial statements, income and expenses during the reporting period and the related disclosures. Although our estimates contemplate current conditions and how we expect them to change in the future, it is reasonably possible that actual conditions could be worse than anticipated in those estimates, which could materially affect our results of operations and financial condition. Management has made significant estimates in several areas, including: • allowance for credit losses (Note 6 (Loans and Related Allowance for Credit Losses); • valuations of residential mortgage servicing rights (MSRs) (Note 10 (Securitizations and Variable Interest Entities) and Note 11 (Mortgage Banking Activities)); • valuations of financial instruments (Note 15 (Derivatives) and Note 16 (Fair Values of Assets and Liabilities)); • liabilities for contingent litigation losses (Note 14 (Legal Actions)); and • income taxes. Actual results could differ from those estimates.
Comparability of Prior Year Financial Data	These unaudited interim financial statements reflect all adjustments that are, in the opinion of management, necessary for a fair statement of the results for the periods presented. These adjustments are of a normal recurring nature, unless otherwise disclosed in this Form 10-Q. The results of operations in the interim financial statements do not necessarily indicate the results that may be expected for the full year. The interim financial information should be read in conjunction with our 2019 Form 10-K.
Accounting Standards Adopted in 2020	Accounting Standards Adopted in 2020 In 2020 , we adopted the following new accounting guidance: • Accounting Standards Update (ASU or Update) 2020-04 – Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting • ASU 2019-04 – Codification Improvements to Topic 326, Financial Instruments – Credit Losses , Topic 815, Derivatives and Hedging , and Topic 825, Financial Instruments . This Update includes guidance on recoveries of financial assets, which is included in the discussion for ASU 2016-13 below. • ASU 2018-17 – Consolidation (Topic 810): Targeted Improvements to Related Party Guidance for Variable Interest Entities • ASU 2018-15 – Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (a consensus of the Financial Accounting Standards Board (FASB) Emerging Issues Task Force) • ASU 2018-13 – Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement. • ASU 2017-04 – Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment • ASU 2016-13 – Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments and related subsequent Updates
Interest Income and Gain (Loss) Recognition [Policy Text Block]	INTEREST INCOME AND GAIN/LOSS RECOGNITION Unamortized premiums and discounts are recognized in interest income over the contractual life of the security using the effective interest method, except for purchased callable debt securities carried at a premium. For purchased callable debt securities carried at a premium, the premium is amortized into interest income to the earliest call date using the effective interest method. As principal repayments are received on securities (e.g., mortgage-backed securities (MBS)), a proportionate amount of the related premium or discount is recognized in income so that the effective interest rate on the remaining portion of the security continues unchanged. We recognize realized gains and losses on the sale of debt securities in net gains (losses) on debt securities within noninterest income using the specific identification method.
Credit Loss, Financial Instrument [Policy Text Block]	IMPAIRMENT AND CREDIT LOSSES Unrealized losses of AFS debt securities are driven by a number of factors, including changes in interest rates and credit spreads which impact most types of debt securities with additional considerations for certain types of debt securities: • Debt securities of U.S. Treasury and federal agencies, including federal agency MBS, are not impacted by credit movements given the explicit or implicit guarantees provided by the U.S. government. • Debt securities of U.S. states and political subdivisions are most impacted by changes in the relationship between municipal and term funding credit curves rather than by changes in the credit quality of the underlying securities. • Structured securities, such as MBS and collateralized loan obligations (CLO), are also impacted by changes in projected collateral losses of assets underlying the security. For debt securities where fair value is less than amortized cost basis, we recognize impairment in earnings if we have the intent to sell the security or if it is more likely than not that we will be required to sell the security before recovery of its amortized cost basis. Impairment is recognized equal to the entire difference between the amortized cost basis and the fair value of the security and is classified as net gains (losses) from debt securities within noninterest income. Following the recognition of impairment, the security’s new amortized cost basis is the previous basis less impairment. For debt securities where fair value is less than amortized cost basis where we did not recognize impairment in earnings, we set up an allowance for credit losses as of the balance sheet date. See “Allowance for Credit Losses” section in this Note. TRANSFERS BETWEEN CATEGORIES OF DEBT SECURITIES AFS debt securities transferred to the HTM classification are recorded at fair value and the unrealized gains or losses resulting from the transfer of these securities continue to be reported in cumulative OCI. The cumulative OCI balance is amortized into earnings over the same period as the unamortized premiums and discounts using the effective interest method. Any allowance for credit losses previously recorded under the AFS model on securities transferred to HTM is reversed and an allowance for credit losses is subsequently recorded under the HTM debt security model. NONACCRUAL AND PAST DUE, AND CHARGE-OFF POLICIES We generally place debt securities on nonaccrual status using factors similar to those described for loans. When we place a debt security on nonaccrual status, we reverse the accrued unpaid interest receivable against interest income and suspend the amortization of premiums and accretion of discounts. If the ultimate collectability of the principal is in doubt on a nonaccrual debt security, any cash collected is first applied to reduce the security’s amortized cost basis to zero, followed by recovery of amounts previously charged off, and subsequently to interest income. Generally, we return a debt security to accrual status when all delinquent interest and principal become current under the contractual terms of the security and collectability of remaining principal and interest is no longer doubtful. Our debt securities are considered past due when contractually required principal or interest payments have not been made on the due dates. Our charge-off policy for debt securities are similar to those described for loans. Subsequent to charge-off, the debt security will be designated as nonaccrual and follow the process described above for any cash received. Allowance for Credit Losses The ACL is management’s estimate of the current expected credit losses in the loan portfolio and unfunded credit commitments, at the balance sheet date, excluding loans and unfunded credit commitments carried at fair value or held for sale. Additionally, we maintain an ACL on AFS and HTM debt securities, other financing receivables measured at amortized cost, and other off-balance sheet credit exposures. While we attribute portions of the allowance to specific financial asset classes (loan and debt security portfolios), loan portfolio segments (commercial and consumer) or major security type, the entire ACL is available to absorb credit losses of the Company. Our ACL process involves procedures to appropriately consider the unique risk characteristics of our financial asset classes, portfolio segments, and major security types. For each loan portfolio segment and each major HTM debt security type, losses are estimated collectively for groups of loans or securities with similar risk characteristics. For loans and securities that do not share similar risk characteristics with other financial assets, the losses are estimated individually, which primarily includes our impaired large commercial loans and non-accruing HTM debt securities. For AFS debt securities, losses are estimated at the tax-lot level. Our ACL amounts are influenced by a variety of factors, including changes in loan and debt security volumes, portfolio credit quality, and general economic conditions. General economic conditions are forecasted using economic variables which will create volatility as those variables change over time. See Table 1.2 for key economic variables used for our loan portfolios. Table 1.2: Key Economic Variables Loan Portfolio Key economic variables Total commercial • Gross domestic product • Commercial real estate asset prices, where applicable • Unemployment rate • Corporate investment-grade bond spreads Real estate 1-4 family mortgage • Home price index • Unemployment rate Other consumer (including credit card, automobile, and other revolving credit and installment) • Unemployment rate Our approach for estimating expected life-time credit losses for loans and debt securities includes the following key components: • An initial loss forecast period of one year for all portfolio segments and classes of financing receivables and off-balance-sheet credit exposures. This period reflects management’s expectation of losses based on forward-looking economic scenarios over that time. • A historical loss forecast period covering the remaining contractual term, adjusted for expected prepayments and certain expected extensions, renewals, or modifications, by portfolio segment and class of financing receivables based on the changes in key historical economic variables during representative historical expansionary and recessionary periods. • A reversion period of up to two years to connect the losses estimated for our initial loss forecast period to the period of our historical loss forecast based on economic conditions at the measurement date. Our reversion methodology considers the type of portfolio, point in the credit cycle, expected length of recessions and recoveries, as well as other relevant factors. • Utilization of discounted cash flow (DCF) methods to measure credit impairment for loans modified in a troubled debt restructuring, unless they are collateral dependent and measured at the fair value of the collateral. The DCF methods obtain estimated life-time credit losses using the initial and historical mean loss forecast periods described above. • For AFS debt securities and certain beneficial interests classified as HTM, we utilize the DCF methods to measure the ACL, which incorporate expected credit losses using the conceptual components described above. The ACL on AFS debt securities is subject to a limitation based on the fair value of the debt securities (fair value floor). The ACL for financial assets held at amortized cost and AFS debt securities will be reversible with immediate recognition of recovery in earnings if credit improves. The ACL for financial assets held at amortized cost is a valuation account that is deducted from, or added to, the amortized cost basis of the financial assets to present the net amount expected to be collected, which can include a negative allowance limited to the cumulative amounts previously charged off. For financial assets with an ACL estimated using DCF methods, changes in the ACL due to the passage of time are recorded in interest income. The ACL for AFS debt securities reflects the amount of unrealized loss related to expected credit losses, limited by the amount that fair value is less than the amortized cost basis, and cannot have an associated negative allowance. For certain financial assets, such as residential real estate loans guaranteed by the Government National Mortgage Association (GNMA), an agency of the federal government, U. S. Treasury and Agency mortgage backed debt securities, as well as certain sovereign debt securities, the Company has not recognized an ACL as our expectation of nonpayment of the amortized cost basis, based on historical losses, adjusted for current conditions and reasonable and supportable forecasts, is zero. A financial asset is collateral-dependent when the borrower is experiencing financial difficulty and repayment is expected to be provided substantially through the sale or operation of the collateral. When a collateral-dependent financial asset is probable of foreclosure, we will measure the ACL based on the fair value of the collateral. If we intend to sell the underlying collateral, we will measure the ACL based on the collateral’s net realizable value (fair value of collateral, less estimated costs to sell). In most situations, based on our charge-off policies, we will immediately write-down the financial asset to the fair value of the collateral or net realizable value. For consumer loans, collateral-dependent financial assets may have collateral in the form of residential real estate, automobiles or other personal assets. For commercial loans, collateral-dependent financial assets may have collateral in the form of commercial real estate or other business assets. We do not generally record an ACL for accrued interest receivables because uncollectible accrued interest is reversed through interest income in a timely manner in line with our non-accrual and past due policies for loans and debt securities. For consumer credit card and certain consumer lines of credit, we include an ACL for accrued interest and fees since these loans are not placed on nonaccrual status and written off until the loan is 180 days past due. Accrued interest receivables are included in other assets, except for certain revolving loans, such as credit card loans. COMMERCIAL LOAN PORTFOLIO SEGMENT ACL METHODOLOGY Generally, commercial loans, which include net investments in lease financing, are assessed for estimated losses by grading each loan using various risk factors as identified through periodic reviews. Our estimation approach for the commercial portfolio reflects the estimated probability of default in accordance with the borrower’s financial strength and the severity of loss in the event of default, considering the quality of any underlying collateral. Probability of default and severity at the time of default are statistically derived through historical observations of default and losses after default within each credit risk rating. These estimates are adjusted as appropriate based on additional analysis of long-term average loss experience compared with previously forecasted losses, external loss data or other risks identified from current economic conditions and credit quality trends. The estimated probability of default and severity at the time of default are applied to loan equivalent exposures to estimate losses for unfunded credit commitments. CONSUMER LOAN PORTFOLIO SEGMENT ACL METHODOLOGY For consumer loans, we determine the allowance at the individual loan level. When developing historical loss experience, we pool loans, generally by product types with similar risk characteristics, such as residential real estate mortgages and credit cards. As appropriate and to achieve greater accuracy, we may further stratify selected portfolios by sub-product, origination channel, vintage, loss type, geographic location and other predictive characteristics. We use pooled loan data such as historic delinquency and default and loss severity in the development of our consumer loan models, in addition to home price trends, unemployment trends, and other economic variables that may influence the frequency and severity of losses in the consumer portfolio. AFS PORTFOLIO ACL METHODOLOGY We develop our ACL estimate for AFS debt securities by utilizing a security-level multi-scenario, probability-weighted discounted cash flow model based on a combination of past events, current conditions, as well as reasonable and supportable forecasts. The projected cash flows are discounted at the security’s effective interest rate, except for certain variable rate securities which are discounted using projections of future changes in interest rates, prepayable securities which are adjusted for estimated prepayments, and securities part of a fair value hedge which use hedge-adjusted assumptions. The ACL on an AFS debt security is limited to the difference between its amortized cost basis and fair value (fair value floor) and reversals of the allowance are permitted up to the amount previously recorded. HTM PORTFOLIO ACL METHODOLOGY For most HTM debt securities, the ACL is measured using an expected loss model, similar to the methodology used for loans. Unlike AFS debt securities, the ACL on an HTM debt security is not limited to the fair value floor. Certain beneficial interests categorized as HTM debt securities utilize a similar discounted cash flow model as described for AFS debt securities, without the limitation of the fair value floor. OTHER QUALITATIVE FACTORS The ACL includes amounts for qualitative factors which may not be adequately reflected in our loss models. These amounts represent management’s judgment of risks in the processes and assumptions used in establishing the ACL. Generally, these amounts are established at a granular level below our loan portfolio segments. We also consider economic environmental factors, modeling assumptions and performance, process risk, and other subjective factors, including industry trends and emerging risk assessments. OFF-BALANCE SHEET CREDIT EXPOSURES Our off-balance sheet credit exposures include unfunded loan commitments (generally in the form of revolving lines of credit), financial guarantees not accounted for as insurance contracts or derivatives, including standby letters of credit, and other similar instruments. For off-balance sheet credit exposures, we recognize an ACL associated with the unfunded amounts. We do not recognize an ACL for commitments that are unconditionally cancelable at our discretion. Additionally, we recognize an ACL for financial guarantees that create off-balance sheet credit exposure, such as loans sold with credit recourse and factoring guarantees. ACL for off-balance sheet credit exposures are reported as a liability in accrued expenses and other liabilities on our consolidated balance sheet. OTHER FINANCIAL ASSETS Other financial assets are evaluated for expected credit losses. These other financial assets include accounts receivable for fees, receivables from government-sponsored entities, such as Federal National Mortgage Association (FNMA) and Federal Home Loan Mortgage Corporation (FHLMC), and GNMA, and other accounts receivable from high-credit quality counterparties, such as central clearing counterparties. Many of these financial assets are generally not expected to have an ACL as there is a zero loss expectation (for example, government guarantee) or no historical credit losses. Some financial assets, such as loans to employees, maintain an ACL that is presented on a net basis with the related amortized cost amounts in other assets on our consolidated balance sheet. Given the nature of these financial assets, provision for credit losses is not recognized separately from the regular income or expense associated with these financial assets. Securities purchased under resale agreements are generally over-collateralized by securities or cash and are generally short-term in nature. We have elected the practical expedient for these financial assets given collateral maintenance provisions. These provisions require that we monitor the collateral value and customers are required to replenish collateral, if needed. Accordingly, we generally do not maintain an ACL for these financial assets. PURCHASED CREDIT DETERIORATED FINANCIAL ASSETS Financial assets acquired that are of poor credit quality and with more than an insignificant evidence of credit deterioration since their origination or issuance are PCD assets. PCD assets are recorded at their purchase price plus an ACL estimated at the time of acquisition. Under this approach, there is no provision for credit losses recognized at acquisition; rather, there is a gross-up of the purchase price of the financial asset for the estimate of expected credit losses and a corresponding ACL recorded. Changes in estimates of expected credit losses after acquisition are recognized as provision for credit losses (or reversal of provision for credit losses) in subsequent periods. In general, interest income recognition for PCD financial assets is consistent with interest income recognition for the similar non-PCD financial asset.
CARES Act [Policy Text Block]	Troubled Debt Restructuring and Other Relief Related to COVID-19 On March 25, 2020, the U.S. Senate approved the Coronavirus, Aid, Relief, and Economic Security Act (the CARES Act) providing optional, temporary relief from accounting for certain loan modifications as troubled debt restructurings (TDRs). Under the CARES Act, TDR relief is available to banks for loan modifications related to the adverse effects of Coronavirus Disease 2019 (COVID-19) (COVID-related modifications) granted to borrowers that are current as of December 31, 2019. TDR relief applies to COVID-related modifications made from March 1, 2020, until the earlier of December 31, 2020, or 60 days following the termination of the national emergency declared by the President of the United States. In first quarter 2020, we elected to apply the TDR relief provided by the CARES Act. On April 7, 2020, federal banking regulators issued the Interagency Statement on Loan Modifications and Reporting for Financial Institutions Working with Customers Affected by the Coronavirus (Revised) (the Interagency Statement). The guidance in the Interagency Statement provides additional TDR relief as it clarifies that it is not necessary to consider the impact of the COVID-19 pandemic on the financial condition of a borrower in connection with a short-term (e.g., six months or less) COVID-related modification provided the borrower is current at the date the modification program is implemented. For COVID-related modifications in the form of payment deferrals, delinquency status will not advance and loans that were accruing at the time the relief is provided will generally not be placed on nonaccrual status during the deferral period. COVID- related modifications that do not meet the provisions of the CARES Act or the Interagency Statement will be assessed for TDR classification. On April 10, 2020, the FASB Staff issued Accounting for Lease Concessions Related to the Effects of the COVID-19 Pandemic , a question and answer guide. The guide provided an election for leases accounted for under Accounting Standards Codification (ASC) 842, Leases , that were modified due to COVID-19 and met certain criteria in order to not require a new lease classification test upon modification. In second quarter 2020, we elected to apply the lease modification relief provided by the guide.
Private Share Repurchases	Share Repurchases During the first quarter of 2020 and 2019, we repurchased shares of our common stock under Rule 10b5-1 repurchase plans. On March 15, 2020, we, along with the other members of the Financial Services Forum, suspended our share repurchase activities for the remainder of the first quarter and for second quarter 2020. On June 25, 2020, the Board of Governors of the Federal Reserve System (FRB) announced that it was prohibiting large bank holding companies (BHCs) subject to the FRB’s capital plan rule, including Wells Fargo, from making any capital distribution (excluding any capital distribution arising from the issuance of a capital instrument eligible for inclusion in the numerator of a regulatory capital ratio), unless otherwise approved by the FRB. Through the end of third quarter 2020, the FRB is authorizing each BHC to (i) make share repurchases relating to issuances of common stock related to employee stock ownership plans; (ii) provided that the BHC does not increase the amount of its common stock dividends, pay common stock dividends that do not exceed an amount equal to the average of the BHC’s net income for the four preceding calendar quarters, unless otherwise specified by the FRB; and (iii) make scheduled payments on additional tier 1 and tier 2 capital instruments. These provisions may be extended by the FRB quarter-by-quarter. For more information about share repurchases, see Note 1 (Summary of Significant Accounting Policies) in our 2019 Form 10-K.
Accounting Standards Update 2018-17 [Member]
Significant Accounting Policies [Line Items]
Accounting Standards Adopted in 2020	ASU 2018-17 updates the guidance used by decision-makers of VIEs. Indirect interests held through related parties in common control arrangements will be considered on a proportional basis for determining whether fees paid to decision-makers and service providers are variable interests. This is consistent with how indirect interests held through related parties under common control are considered for determining whether a reporting entity must consolidate a VIE. The Update did not have a material impact on our consolidated financial statements.

Accounting Standards Adopted in 2020	ASU 2018-15 clarifies the accounting for implementation costs related to a cloud computing arrangement that is a service contract and enhances disclosures around implementation costs for internal-use software and cloud computing arrangements. The guidance aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). It also requires the expense related to the capitalized implementation costs be presented in the same line item in the statement of income as the fees associated with the hosting element of the arrangement and capitalized implementation costs be presented in the balance sheet in the same line item that a prepayment for the fees of the associated hosting arrangement are presented. The Update did not have a material impact on our consolidated financial statements.

Significant Accounting Policies [Line Items]
Accounting Standards Adopted in 2020	ASU 2018-13 clarifies, eliminates and adds certain fair value measurement disclosure requirements for assets and liabilities, which affects our disclosures in Note 16 (Fair Values of Assets and Liabilities). Although the ASU became effective on January 1, 2020, it permitted early adoption of individual requirements without causing others to be early adopted and, as such, we partially adopted the Update during third quarter 2018 and the remainder of the requirements in first quarter 2020. The Update did not have a material impact on our consolidated financial statements.
Accounting Standards Update 2017-04 [Member]
Significant Accounting Policies [Line Items]
Accounting Standards Adopted in 2020	ASU 2017-04 simplifies the goodwill impairment test by eliminating the requirement to assign the fair value of a reporting unit to all of the assets and liabilities of that unit (including any unrecognized intangible assets) as if the reporting unit had been acquired in a business combination. The Update requires that a goodwill impairment loss is recognized if the fair value of the reporting unit is less than the carrying amount, including goodwill. The goodwill impairment loss is limited to the amount of goodwill allocated to the reporting unit. The guidance did not change the qualitative assessment of goodwill. This guidance is applied on a prospective basis, and accordingly, the Update did not have a material impact on our consolidated financial statements.
Accounting Standards Update 2016-13 [Member]
Significant Accounting Policies [Line Items]
Accounting Standards Adopted in 2020	ASU 2016-13 changes the accounting for the measurement of credit losses on loans and debt securities. For loans and held-to-maturity (HTM) debt securities, the Update requires a current expected credit loss (CECL) measurement to estimate the allowance for credit losses (ACL) for the remaining contractual term, adjusted for prepayments, of the financial asset (including off-balance sheet credit exposures) using historical experience, current conditions, and reasonable and supportable forecasts. Also, the Update eliminates the existing guidance for purchased credit-impaired (PCI) loans, but requires an allowance for purchased financial assets with more than an insignificant deterioration of credit since origination. In addition, the Update modifies the other-than-temporary impairment (OTTI) model for available-for-sale (AFS) debt securities to require an allowance for credit impairment instead of a direct write-down, which allows for reversal of credit impairments in future periods based on improvements in credit. Upon adoption, we recognized an overall decrease in our ACL of approximately $1.3 billion (pre-tax) as a cumulative effect adjustment from a change in accounting policies, which increased our retained earnings and regulatory capital amounts and ratios. Loans previously classified as PCI were automatically transitioned to purchased credit-deteriorated (PCD) classification. We recognized an ACL for these new PCD loans and made a corresponding adjustment to the loan balance, with no impact to net income or transition adjustment to retained earnings. For more information on the impact of CECL by type of financial asset, see Table 1.1 below.

The adoption of ASU 2016-13 did not result in a change to accounting policies, except as noted herein. Our accounting policy for the ACL was updated and is now inclusive of loans, debt securities and other financing receivables. Other than the ACL and the elimination of PCI loans, there were no changes to accounting policies for loans as described in the 2019 Form 10-K. For debt securities, other than the policies with respect to the ACL, all of the current accounting policies, including those that changed as a result of CECL adoption, are included below under Debt Securities.
Accounting Standards Update 2020-04 [Member]
Significant Accounting Policies [Line Items]
Accounting Standards Adopted in 2020	ASU 2020-04 provides optional, temporary relief to ease the burden of accounting for reference rate reform activities that affect contractual modifications of floating rate financial instruments indexed to interbank offering rates (IBORs) and hedge accounting relationships. Modifications of qualifying contracts are accounted for as the continuation of an existing contract rather than as a new contract. Modifications of qualifying hedging relationships will not require discontinuation of the existing hedge accounting relationships. The application of the relief for qualifying existing hedging relationships may be made on a hedge-by-hedge basis and across multiple reporting periods. We adopted ASU 2020-04 on April 1, 2020, and the guidance will be followed until the Update terminates on December 31, 2022. This guidance is applied on a prospective basis. The Update did not have a material impact on our consolidated financial statements in second quarter 2020.

Significant Accounting Policies [Line Items]
Marketable and Nonmarketable Securities, Policy [Policy Text Block]	Debt Securities Our investments in debt securities that are not held for trading purposes are classified as either debt securities available-for-sale (AFS) or held-to-maturity (HTM). Investments in debt securities for which the Company does not have the positive intent and ability to hold to maturity are classified as AFS. AFS debt securities are measured at fair value, with unrealized gains and losses reported in cumulative other comprehensive income (OCI), net of the allowance for credit losses and applicable income taxes. Investments in debt securities for which the Company has the positive intent and ability to hold to maturity are classified as HTM. HTM debt securities are measured at amortized cost, net of allowance for credit losses.

Accounts, Notes, Loans and Financing Receivable, Gross, Allowance, and Net [Abstract]
Loans Outstanding	Table 6.1 presents total loans outstanding by portfolio segment and class of financing receivable. Outstanding balances include unearned income, net deferred loan fees or costs, and unamortized discounts and premiums. These amounts were less than 1% of our total loans outstanding at June 30, 2020 , and December 31, 2019 . Outstanding balances exclude accrued interest receivable on loans, except for certain revolving loans, such as credit card loans. During the first half of 2020 , we reversed accrued interest receivable by reversing interest income of $21 million for our commercial portfolio segment and $114 million for our consumer portfolio segment. See Note 9 (Other Assets) for additional information on accrued interest receivable.

Loan Purchases, Sales and Transfers	Table 6.3 summarizes the proceeds paid or received for purchases and sales of loans and transfers from loans held for investment to mortgages/loans held for sale. The table excludes loans for which we have elected the fair value option and government insured/guaranteed real estate 1-4 family first mortgage loans because their loan activity normally does not impact the ACL. In the first half of 2020 , we sold $1.2 billion of 1-4 family first mortgage loans for a gain of $724 million , which is included in other noninterest income on our consolidated income statement. These whole loans were designated as MLHFS in 2019.

Allowance for Credit Losses for Loans	Table 6.5 presents the allowance for credit losses for loans, which consists of the allowance for loan losses and the allowance for unfunded credit commitments. On January 1, 2020, we adopted CECL. Additional information on our adoption of CECL is included in Note 1 (Summary of Significant Accounting Policies). In second quarter 2020, ACL for loans increased $8.4 billion driven by current and forecasted economic conditions due to the COVID-19 pandemic. These expected impacts were most significantly affected by anticipated changes to economic variables, as well as higher expected losses in the commercial real estate and consumer real estate mortgage loan portfolios and expected impacts of lower oil prices and deteriorating credit trends on the oil and gas portfolio.

Consumer Loan Categories by Delinquency Status and Vintage	Table 6.10 provides the outstanding balances of our consumer portfolio by delinquency status. Payment deferral activities instituted in response to the COVID-19 pandemic may delay recognition of delinquencies for customers who otherwise would have moved into past due status. In connection with our adoption of CECL, credit quality information is provided with the year of origination for term loans. Revolving loans may convert to term loans as a result of a contractual provision in the original loan agreement or if modified in a TDR. The revolving loans converted to term loans in the credit card loan category represent credit card loans with modified terms that require payment over a specific term.

Consumer Loan Categories by FICO and Vintage	Table 6.11 provides a breakdown of our consumer portfolio by FICO. Substantially all of the scored consumer portfolio has an updated FICO of 680 and above, reflecting a strong current borrower credit profile. FICO is not available for certain loan types, or may not be required if we deem it unnecessary due to strong collateral and other borrower attributes. Loans not requiring a FICO score totaled $9.5 billion and $9.1 billion at June 30, 2020 , and December 31, 2019 , respectively. Substantially all loans not requiring a FICO score are securities-based loans originated through retail brokerage.

Consumer Loan Categories by LTV/CLTV and Vintage	Table 6.12 shows the most updated LTV and CLTV distribution of the real estate 1-4 family first and junior lien mortgage loan portfolios. We consider the trends in residential real estate markets as we monitor credit risk and establish our allowance for credit losses. In the event of a default, any loss should be limited to the portion of the loan amount in excess of the net realizable value of the underlying real estate collateral value. Certain loans do not have an LTV or CLTV due to industry data availability and portfolios acquired from or serviced by other institutions.

Nonaccrual Loans	Table 6.13 provides loans on nonaccrual status. In connection with our adoption of CECL, nonaccrual loans may have an allowance for credit losses or a negative allowance for credit losses from expected recoveries of amounts previously written off. Payment deferral activities instituted in response to the COVID-19 pandemic may delay recognition of delinquencies for customers who otherwise would have moved into nonaccrual status.

Impaired Loans Summary	Table 6.15 summarizes key information for impaired loans. Our impaired loans at December 31, 2019 , predominantly included loans on nonaccrual status in the commercial portfolio segment and loans modified in a TDR, whether on accrual or nonaccrual status. Impaired loans generally had estimated losses which are included in the allowance for credit losses. We did have impaired loans with no allowance for credit losses when the loss content has been previously recognized through charge-offs, such as collateral dependent loans, or when loans are currently performing in accordance with their terms and no loss has been estimated. Impaired loans excluded PCI loans and loans that had been fully charged off or otherwise had zero recorded investment. Table 6.15 included trial modifications that totaled $115 million at December 31, 2019 . For additional information on our legacy impaired loans and allowance for credit losses, see Note 1 (Summary of Significant Accounting Policies) in our 2019 Form 10-K.

TDRs may have multiple types of concessions, but are presented only once in the first modification type based on the order presented in the table above. The reported amounts include loans remodified of $221 million and $323 million for the quarters ended June 30, 2020 and 2019 , respectively, and $484 million and $683 million for the first half of 2020 and 2019 , respectively. (2) Principal modifications include principal forgiveness at the time of the modification, contingent principal forgiveness granted over the life of the loan based on borrower performance, and principal that has been legally separated and deferred to the end of the loan, with a zero percent contractual interest rate. (3) Other concessions include loans discharged in bankruptcy, loan renewals, term extensions and other interest and noninterest adjustments, but exclude modifications that also forgive principal and/or reduce the contractual interest rate. (4) Charge-offs include write-downs of the investment in the loan in the period it is contractually modified. The amount of charge-off will differ from the modification terms if the loan has been charged down prior to the modification based on our policies. In addition, there may be cases where we have a charge-off/down with no legal principal modification. Modifications resulted in deferring or legally forgiving principal (actual or contingent) of $3 million and $3 million for the quarters ended June 30, 2020 and 2019 , respectively, and $32 million and $6 million for the first half of 2020 and 2019 , respectively. (5) Reflects the effect of reduced interest rates on loans with an interest rate concession as one of its concession types, which includes loans reported as a principal primary modification type that also have an interest rate concession. (6) Trial modifications are granted a delay in payments due under the original terms during the trial payment period. However, these loans continue to advance through delinquency status and accrue interest according to their original terms. Any subsequent permanent modification generally includes interest rate related concessions; however, the exact concession type and resulting financial effect are usually not known until the loan is permanently modified. Trial modifications for the period are presented net of previously reported trial modifications that became permanent in the current period.
Defaulted TDRs	Table 6.18 summarizes permanent modification TDRs that have defaulted in the current period within 12 months of their permanent modification date. We are reporting these defaulted TDRs based on a payment default definition of 90 days past due for the commercial portfolio segment and 60 days past due for the consumer portfolio segment.

Unconsolidated VIEs	Table 10.2 provides a summary of our exposure to unconsolidated VIEs with which we have significant continuing involvement but for which we are not the primary beneficiary. We include transactions where we were the sponsor or servicer and also have other significant forms of continuing involvement. Sponsorship includes transactions where we solely or materially participated in the initial design or structuring of the VIE or marketed the transaction to investors. We consider investments in securities, loans, guarantees, liquidity agreements, commitments and certain derivatives to be other forms of continuing involvement that may be significant. We also include transactions where we transferred assets to a VIE, account for the transfer as a sale, and service the VIE collateral or have other forms of continuing involvement that may be significant (as described above).

Transfers with Continuing Involvement	Table 10.3 presents information about transfers of assets during the period to unconsolidated VIEs or third-party investors for which we recorded the transfers as sales and have continuing involvement with the transferred assets. In connection with these transfers, we recorded servicing assets, securities, and a liability for repurchase losses which reflects management’s estimate of probable losses related to various representations and warranties for the loans transferred. Each of these interests are initially measured at fair value. Servicing rights are classified as Level 3 measurements, and generally securities are initially classified as Level 2. Sales with continuing involvement include securitizations of conforming residential mortgages that are sold to the government-sponsored entities (GSEs) or GNMA. Substantially all transfers to these entities resulted in no gain or loss because the loans were already measured at fair value on a recurring basis.

Residential Mortgage Servicing Rights	Table 10.4 presents the key weighted-average assumptions we used to measure residential MSRs at the date of securitization. Table 10.4: Residential Mortgage Servicing Rights Residential mortgage servicing rights 2020 2019 Quarter ended June 30, Prepayment speed (1) 15.0 % 13.5 Discount rate 7.0 7.5 Cost to service ($ per loan) (2) $ 97 121 Six months ended June 30, Prepayment speed (1) 14.0 % 13.5 Discount rate 6.8 7.7 Cost to service ($ per loan) (2) $ 94 109 (1) The prepayment speed assumption for residential MSRs includes a blend of prepayment speeds and default rates. Prepayment speed assumptions are influenced by mortgage interest rate inputs as well as our estimation of drivers of borrower behavior. (2) Includes costs to service and unreimbursed foreclosure costs, which can vary period to period due to changes in model assumptions and the mix of modified government-guaranteed loans sold to GNMA.
Cash Inflows (Outflows) from Sales and Securitization Activity	Table 10.5 presents the proceeds related to transfers accounted for as sales in which we have continuing involvement with the transferred financial assets, as well as current period cash flows from continuing involvement with previous transfers accounted for as sales. Cash flows from other interests held predominantly include principal and interest payments received on retained bonds. Repurchases of assets represents cash paid to repurchase loans from investors under representation and warranty obligations or in connection with the exercise of cleanup calls on securitizations. Loss reimbursements is cash paid to reimburse investors for losses on individual loans that are already liquidated. Government insured loans are delinquent loans that we service and have exercised our option to purchase out of GNMA pools. These loans are insured by the FHA or guaranteed by the VA. Table 10.5: Cash Inflows (Outflows) From Sales and Securitization Activity Mortgage loans (in millions) 2020 2019 Quarter ended June 30, Proceeds from securitizations and whole loan sales $ 65,009 39,697 Fees from servicing rights retained 663 786 Cash flows from other interests held 192 133 Repurchases of assets/loss reimbursements: Non-agency securitizations and whole loan transactions (1 ) (1 ) Government insured loans (3,594 ) (1,246 ) Agency securitizations (35 ) (27 ) Servicing advances, net of recoveries (1) (93 ) 54 Six months ended June 30, Proceeds from securitizations and whole loan sales $ 115,238 76,204 Fees from servicing rights retained 1,419 1,566 Cash flows from other interests held 359 244 Repurchases of assets/loss reimbursements: Non-agency securitizations and whole loan transactions (1 ) (1 ) Government insured loans (5,034 ) (3,188 ) Agency securitizations (61 ) (44 ) Servicing advances, net of recoveries (1) (60 ) 93 (1) Cash flows from servicing advances includes principal and interest payments to investors required by servicing agreements.
Retained Interests from Unconsolidated VIEs	Table 10.6 provides key economic assumptions and the sensitivity of the current fair value of residential MSRs and other interests held related to unconsolidated VIEs to immediate adverse changes in those assumptions. Amounts for residential MSRs include purchased servicing rights as well as servicing rights resulting from the transfer of loans. See Note 16 (Fair Values of Assets and Liabilities) for additional information on key economic assumptions for residential MSRs. “Other interests held” were obtained when we securitized residential and commercial mortgage loans. Residential mortgage-backed securities retained in securitizations issued through GSEs or GNMA, are excluded from the table because these securities have a remote risk of credit loss due to the GSE or government guarantee. These securities also have economic characteristics similar to GSE or GNMA mortgage-backed securities that we purchase, which are not included in the table. Subordinated interests include only those bonds whose credit rating was below AAA by a major rating agency at issuance. Senior interests include only those bonds whose credit rating was AAA by a major rating agency at issuance. The information presented excludes trading positions held in inventory.

Off-Balance Sheet Loans Sold or Securitized	Table 10.7 presents information about the principal balances of off-balance sheet loans that were sold or securitized, including residential mortgage loans sold to FNMA, FHLMC, GNMA and other investors, for which we have some form of continuing involvement (including servicer). Delinquent loans include loans 90 days or more past due and loans in bankruptcy, regardless of delinquency status. In accordance with applicable servicing guidelines, delinquency status continues to advance for loans with COVID-related payment deferrals. For loans sold or securitized where servicing is our only form of continuing involvement, we would only experience a loss if we were required to repurchase a delinquent loan or foreclosed asset due to a breach in representations and warranties associated with our loan sale or servicing contracts.

Transactions with Consolidated VIEs and Secured Borrowings	Table 10.8 presents a summary of financial assets and liabilities for asset transfers accounted for as secured borrowings and involvements with consolidated VIEs. Carrying values of “Assets” are presented using GAAP measurement methods, which may include fair value, credit impairment or other adjustments, and therefore in some instances will differ from “Total VIE assets.” For VIEs that obtain exposure synthetically through derivative instruments, the notional amount of the derivative is included in “Total VIE assets.” On the consolidated balance sheet, we separately disclose the consolidated assets of certain VIEs that can only be used to settle the liabilities of those VIEs.

Pledged Assets	Table 13.2 provides the carrying amount of on-balance sheet pledged assets and the fair value of other pledged collateral. Other pledged collateral is collateral we have received from third parties, have the right to repledge and is not recognized on our balance sheet. TRADING RELATED ACTIVITY Our trading businesses may pledge debt and equity securities in connection with securities sold under agreements to repurchase (repurchase agreements) and securities lending arrangements. The collateral that we pledge related to our trading activities may include our own collateral as well as collateral that we have received from third parties and have the right to repledge. All of the trading activity pledged collateral is eligible to be repledged or sold by the secured party. NON-TRADING RELATED ACTIVITY As part of our liquidity management strategy, we may pledge loans, debt securities, and other assets to secure trust and public deposits, borrowings and letters of credit from the Federal Home Loan Bank (FHLB) and FRB and for other purposes as required or permitted by law or insurance statutory requirements. Substantially all of the non-trading activity pledged collateral is not eligible to be repledged or sold by the secured party. VIE RELATED We pledge assets in connection with various types of transactions entered into with VIEs. These pledged assets can only be used to settle the liabilities of those entities. We also have loans recorded on our balance sheet which represent certain delinquent loans that are eligible for repurchase from GNMA loan securitizations. See Note 10 (Securitizations and Variable Interest Entities) for additional information on consolidated VIE assets and VIEs accounted for as secured borrowings.

Offsetting - Securities Financing Activities	Table 13.3 presents resale and repurchase agreements subject to master repurchase agreements (MRA) and securities borrowing and lending agreements subject to master securities lending agreements (MSLA). Collateralized financings with a single counterparty are presented net on our balance sheet, provided certain criteria are met that permit balance sheet netting. Most transactions subject to these agreements do not meet those criteria and thus are not eligible for balance sheet netting. Collateral we pledged consists of non-cash instruments, such as securities or loans, and is not netted on the balance sheet against the related liability. Collateral we received includes securities or loans and is not recognized on our balance sheet. Collateral pledged or received may be increased or decreased over time to maintain certain contractual thresholds, as the assets underlying each arrangement fluctuate in value. Generally, these agreements require collateral to exceed the asset or liability recognized on the balance sheet. The following table includes the amount of collateral pledged or received related to exposures subject to enforceable MRAs or MSLAs. While these agreements are typically over-collateralized, U.S. GAAP requires disclosure in this table to limit the reported amount of such collateral to the amount of the related recognized asset or liability for each counterparty. In addition to the amounts included in Table 13.3 , we also have balance sheet netting related to derivatives that is disclosed in Note 15 (Derivatives).

(3) Represents the fair value of collateral we have received under enforceable MRAs or MSLAs, limited in the table above to the amount of the recognized asset due from each counterparty. At June 30, 2020 , and December 31, 2019 , we have received total collateral with a fair value of $122.5 billion and $150.9 billion , respectively, all of which we have the right to sell or repledge. These amounts include securities we have sold or repledged to others with a fair value of $41.1 billion at June 30, 2020 , and $59.1 billion at December 31, 2019 . (4) Represents the amount of our exposure (assets) or obligation (liabilities) that is not collateralized and/or is not subject to an enforceable MRA or MSLA. (5) Amount is classified in short-term borrowings on our consolidated balance sheet. (6) Represents the fair value of collateral we have pledged, related to enforceable MRAs or MSLAs, limited in the table above to the amount of the recognized liability owed to each counterparty. At June 30, 2020 , and December 31, 2019 , we have pledged total collateral with a fair value of $64.3 billion and $113.3 billion , respectively, substantially all of which may be sold or repledged by the counterparty.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Notional or Contractual Amounts and Fair Values of Derivatives	Table 15.1 presents the total notional or contractual amounts and fair values for our derivatives. Derivative transactions can be measured in terms of the notional amount, but this amount is not recorded on the balance sheet and is not, when viewed in isolation, a meaningful measure of the risk profile of the instruments. The notional amount is generally not exchanged but is used only as the basis on which interest and other payments are determined.

Gross Fair Values of Derivative Assets and Liabilities	Table 15.2 provides information on the gross fair values of derivative assets and liabilities, the balance sheet netting adjustments and the resulting net fair value amount recorded on our balance sheet, as well as the non-cash collateral associated with such arrangements. We execute substantially all of our derivative transactions under master netting arrangements and reflect all derivative balances and related cash collateral subject to enforceable master netting arrangements on a net basis within the balance sheet. The “Gross amounts recognized” column in the following table includes $59.6 billion and $54.7 billion of gross derivative assets and liabilities, respectively, at June 30, 2020 , and $33.7 billion and $33.5 billion , respectively, at December 31, 2019 , with counterparties subject to enforceable master netting arrangements that are eligible for balance sheet netting adjustments. The majority of these amounts are interest rate contracts executed in over-the-counter (OTC) markets. The remaining gross derivative assets and liabilities of $8.3 billion and $5.1 billion , respectively, at June 30, 2020 , and $5.6 billion and $4.4 billion , respectively, at December 31, 2019 , include those with counterparties subject to master netting arrangements for which we have not assessed the enforceability because they are with counterparties where we do not currently have positions to offset, those subject to master netting arrangements where we have not been able to confirm the enforceability and those not subject to master netting arrangements. As such, we do not net derivative balances or collateral within the balance sheet for these counterparties. Cash collateral receivables and payables that have not been offset against our derivatives were $1.2 billion and $1.4 billion , respectively, at June 30, 2020 , and $6.3 billion and $1.4 billion , respectively, at December 31, 2019 . We determine the balance sheet netting adjustments based on the terms specified within each master netting arrangement. We disclose the balance sheet netting amounts within the column titled “Gross amounts offset in consolidated balance sheet.” Balance sheet netting adjustments are determined at the counterparty level for which there may be multiple contract types. For disclosure purposes, we allocate these netting adjustments to the contract type for each counterparty proportionally based upon the “Gross amounts recognized” by counterparty. As a result, the net amounts disclosed by contract type may not represent the actual exposure upon settlement of the contracts. We do not net non-cash collateral that we receive and pledge on the balance sheet. For disclosure purposes, we present the fair value of this non-cash collateral in the column titled “Gross amounts not offset in consolidated balance sheet (Disclosure-only netting)” within the table. We determine and allocate the Disclosure-only netting amounts in the same manner as balance sheet netting amounts. The “Net amounts” column within Table 15.2 represents the aggregate of our net exposure to each counterparty after considering the balance sheet and Disclosure-only netting adjustments. We manage derivative exposure by monitoring the credit risk associated with each counterparty using counterparty specific credit risk limits, using master netting arrangements and obtaining collateral. Derivative contracts executed in OTC markets include bilateral contractual arrangements that are not cleared through a central clearing organization but are typically subject to master netting arrangements. Other derivative contracts that are settled through a central clearing organization whether OTC or exchange-traded, are excluded from that percentage. In addition to the netting amounts included in the table, we also have balance sheet netting related to resale and repurchase agreements that are disclosed within Note 13 (Guarantees, Pledged Assets and Collateral, and Other Commitments).

Cash collateral totaled $7.3 billion and $11.0 billion , netted against derivative assets and liabilities, respectively, at June 30, 2020 , and $2.9 billion and $6.8 billion , respectively, at December 31, 2019 .

Valuation Techniques - Recurring Basis	Table 16.11 and Table 16.12 provide quantitative information about the valuation techniques and significant unobservable inputs used in the valuation of substantially all of our Level 3 assets and liabilities measured at fair value on a recurring basis for which we use an internal model. The significant unobservable inputs for Level 3 assets and liabilities inherent in the fair values obtained from third-party vendors are not included in the table, as the specific inputs applied are not provided by the vendor. In addition, the table excludes the valuation techniques and significant unobservable inputs for certain classes of Level 3 assets and liabilities measured using internal models that we consider, both individually and in the aggregate, insignificant relative to our overall Level 3 assets and liabilities. We made this determination based upon an evaluation of each class, which considered the magnitude of the positions, nature of the unobservable inputs and potential for significant changes in fair value due to changes in those inputs. Weighted averages of inputs are calculated using outstanding unpaid principal balance for cash instruments, such as loans and securities, and notional amounts for derivative instruments.

Valuation Techniques - Nonrecurring Basis	Table 16.15 provides quantitative information about the valuation techniques and significant unobservable inputs used in the valuation of our Level 3 assets that are measured at fair value on a nonrecurring basis primarily using an internal model. The table is limited to financial instruments that had nonrecurring fair value adjustments during the periods presented. Weighted averages of inputs are calculated using outstanding unpaid principal balance for cash instruments, such as loans, and carrying value prior to the nonrecurring fair value measurement for nonmarketable equity securities. We have excluded from the table valuation techniques and significant unobservable inputs for certain classes of Level 3 assets we consider both individually and in the aggregate, insignificant relative to our overall Level 3 nonrecurring measurements. We made this determination based upon an evaluation of each class that considered the magnitude of the positions, nature of the unobservable inputs and potential for significant changes in fair value due to changes in those inputs.

Fair Value, Estimates for Financial Instruments	Table 16.19 presents a summary of fair value estimates for financial instruments that are not carried at fair value on a recurring basis. Some financial instruments are excluded from scope of this table, such as certain insurance contracts and leases. This table also excludes assets and liabilities that are not financial instruments such as the value of the long-term relationships with our deposit, credit card and trust customers, MSRs, premises and equipment, goodwill and deferred taxes. Loan commitments, standby letters of credit and commercial and similar letters of credit are not included in Table 16.19 . A reasonable estimate of the fair value of these instruments is the carrying value of deferred fees plus the allowance for unfunded credit commitments, which totaled $1.7 billion and $1.0 billion at June 30, 2020 and December 31, 2019 , respectively. The total of the fair value calculations presented does not represent, and should not be construed to represent, the underlying value of the Company.

(2) Calculated using the treasury stock method. In the second quarter and first half of 2020, diluted average common shares outstanding equaled average common shares outstanding because our securities convertible into common shares had an anti-dilutive effect.
Outstanding Anti-Dilutive Securities	Table 20.2 presents the outstanding securities that were anti-dilutive and therefore not included in the calculation of diluted earnings per common share. Table 20.2: Outstanding Anti-Dilutive Securities Weighted-average shares Quarter ended June 30, Six months ended June 30, (in millions) 2020 2019 2020 2019 Convertible Preferred Stock, Series L (1) 25.3 25.3 25.3 25.3 Restricted share rights (2) 35.9 — 0.9 — (1) Calculated using the if-converted method. (2) Calculated using the treasury stock method. Since we had net losses attributable to common shareholders for the second quarter and first half of 2020 , all RSRs outstanding were anti-dilutive. Weighted average RSRs outstanding were 50.7 million and 54.7 million for the second quarter and first half of 2020 , respectively.

Regulatory and Agency Capital_2

Regulatory and Agency Capital Requirements (Tables)	6 Months Ended

Banking and Thrift [Abstract]
Regulatory Capital Information	Table 23.1 presents regulatory capital information for Wells Fargo & Company and the Bank in accordance with Basel III capital requirements. We must report the lower of our Common Equity Tier 1 (CET1), tier 1 and total capital ratios calculated under the Standardized Approach and under the Advanced Approach in the assessment of our capital adequacy. The Standardized Approach applies assigned risk weights to broad risk categories, while the calculation of risk-weighted assets (RWAs) under the Advanced Approach differs by requiring applicable banks to utilize a risk-sensitive methodology, which relies upon the use of internal credit models, and includes an operational risk component. The Basel III capital requirements for calculating CET1 and tier 1 capital, along with RWAs, are fully phased-in. However, the requirements for determining tier 2 and total capital are still in accordance with Transition Requirements and are scheduled to be fully phased-in by the end of 2021. Accordingly, the information presented below reflects fully phased-in CET1 capital, tier 1 capital, and RWAs, but reflects total capital still in accordance with Transition Requirements. At June 30, 2020 , the Bank and our other insured depository institutions were considered well-capitalized under the requirements of the Federal Deposit Insurance Act. The Bank is an approved seller/servicer of mortgage loans and is required to maintain minimum levels of shareholders’ equity, as specified by various agencies, including the United States Department of Housing and Urban Development, GNMA, FHLMC and FNMA. At June 30, 2020 , the Bank met these requirements. Table 23.1: Regulatory Capital Information (1) Wells Fargo & Company Wells Fargo Bank, N.A.

(1) In second quarter 2020, the Company elected to apply a modified transition provision issued by federal banking regulators in March 2020 related to the impact of CECL on regulatory capital. The rule permits certain banking organizations to exclude from regulatory capital the initial adoption impact of CECL, plus 25% of the cumulative changes in the ACL under CECL for each period until December 31, 2021, followed by a three-year phase-out of the benefits. The impact of the CECL transition provision on the regulatory capital of the Company at June 30, 2020 , was an increase in capital of $1.9 billion , reflecting a $991 million (post-tax) increase in capital recognized upon our initial adoption of CECL, offset by 25% of the $11.4 billion increase in our ACL under CECL from January 1, 2020, through June 30, 2020 . The impact of the CECL transition provision on the regulatory capital of the Bank at June 30, 2020 , was an increase in capital of $1.8 billion . (2) RWAs and capital ratios for December 31, 2019, have been revised as a result of a decrease in RWAs under the Advanced Approach due to the correction of duplicated operational loss amounts. RWAs for the Company and the Bank include an increase of $1.5 billion under both the Advanced Approach and Standardized Approach related to the impact of the CECL transition provision on the excess allowance for credit losses as of June 30, 2020 . (3) The leverage ratio consists of Tier 1 capital divided by total average assets, excluding goodwill and certain other items. (4) The supplementary leverage ratio (SLR) consists of Tier 1 capital divided by total leverage exposure. Total leverage exposure consists of total average assets, less goodwill and other permitted Tier 1 capital deductions (net of deferred tax liabilities), plus certain off-balance sheet exposures.
Minimum Required Regulatory Capital Ratios - Transition Requirements	Table 23.2 presents the minimum required regulatory capital ratios under Transition Requirements to which the Company and the Bank were subject as of June 30, 2020 , and December 31, 2019 . Table 23.2: Minimum Required Regulatory Capital Ratios – Transition Requirements (1) Wells Fargo & Company Wells Fargo Bank, N.A. June 30, 2020 December 31, 2019 June 30, 2020 December 31, 2019 Regulatory capital ratios: Common equity tier 1 capital 9.000 % 9.000 7.000 7.000 Tier 1 capital 10.500 10.500 8.500 8.500 Total capital 12.500 12.500 10.500 10.500 Tier 1 leverage 4.000 4.000 4.000 4.000 Supplementary leverage (2) 5.000 5.000 6.000 6.000 (1) At June 30, 2020 , under transition requirements, the CET1, tier 1 and total capital minimum ratio requirements for the Company include a capital conservation buffer of 2.500% and a global systemically important bank (G-SIB) surcharge of 2.000% . Only the 2.500% capital conservation buffer applies to the Bank at June 30, 2020 . Effective October 1, 2020, the 2.500% capital conservation buffer will be replaced under the Standardized Approach by a stress capital buffer that is calculated annually as part of the FRB's supervisory stress test and related Comprehensive Capital Analysis and Review (CCAR). (2) The Company is required to maintain a SLR of at least 5.000% (comprised of a 3.000% minimum requirement plus a supplementary leverage buffer of 2.000% ) to avoid restrictions on capital distributions and discretionary bonus payments. The Bank is required to maintain a SLR of at least 6.000% to be considered well-capitalized under applicable regulatory capital adequacy guidelines.
