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, investment and mortgage products and services, as well as consumer and commercial finance, through banking locations and offices, the internet and other distribution channels to individuals, businesses and institutions in all 50 states, the District of Columbia, and in countries outside the U.S. 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 a 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, 2023 (2023 Form 10-K). There were no material changes to these policies in the first nine months of 2024. 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 5 (Loans and Related Allowance for Credit Losses) and Note 3 (Available-for-Sale and Held-to-Maturity Debt Securities)); • valuations of residential mortgage servicing rights (MSRs) (Note 6 (Mortgage Banking Activities) and Note 13 (Securitizations and Variable Interest Entities)); • valuations of financial instruments (Note 12 (Fair Values of Assets and Liabilities)); • liability for legal actions (Note 10 (Legal Actions)); • income taxes; and • goodwill impairment (Note 7 (Intangible Assets and Other Assets)). 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 2023 Form 10-K. Accounting Standards Adopted in 2024 In 2024, we adopted the following new accounting guidance: • Accounting Standards Update (ASU) 2023-02, Investments – Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method • ASU 2022-03, Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions ASU 2023-02 expands the use of the proportional amortization method of accounting for tax credit investments, which previously was limited to affordable housing investments that generate low-income housing tax credits. Upon adoption of the Update, an entity may elect to account for equity investments that generate income tax credits and benefits using the proportional amortization method if certain eligibility criteria are met. The proportional amortization method amortizes the cost of a tax credit investment in proportion to the income tax credits and income tax benefits received. The amortization and related income tax credits and benefits are recorded on a net basis within income tax expense. The cost of an investment includes unfunded commitments that are either legally binding or contingent but probable of funding. Such unfunded commitments are not recognized under other methods of accounting. We adopted the Update on January 1, 2024, on a modified retrospective basis with a cumulative effect adjustment to retained earnings. Upon adoption, we elected to account for eligible investments in our renewable energy tax credit portfolio using the proportional amortization method. These investments were previously accounted for using the equity method. We also elected to continue use of the proportional amortization method to account for our affordable housing investments. In addition, we elected to classify liabilities recognized for unfunded commitments related to proportional amortization method investments in accrued expenses and other liabilities on our consolidated balance sheet, including a change to unfunded commitments for affordable housing investments that were previously included in long-term debt. Prior period amounts were not impacted by these accounting changes. Table 1.1 presents the transition adjustments recorded upon the adoption of ASU 2023-02 as of January 1, 2024. Table 1.1: Transition Adjustment of ASU 2023-02 (in millions) Dec 31, Transition adjustment upon adoption Jan 1, Selected Balance Sheet Data Equity securities $ 57,336 1,700 59,036 Other assets 78,815 548 79,363 Accrued expenses and other liabilities 71,210 7,333 78,543 Long-term debt 207,588 (4,927) 202,661 Retained earnings 201,136 (158) 200,978 ASU 2022-03 clarifies the guidance regarding the measurement of fair value of equity securities subject to contractual restrictions that prohibit the sale of the security. Specifically, that such restrictions are not part of the unit of account of the security and therefore are not considered when measuring fair value. We adopted the Update on January 1, 2024, on a prospective basis. The Update did not have a material impact to our consolidated financial statements. Supplemental Cash Flow Information Significant noncash activities are presented in Table 1.2. Table 1.2: Supplemental Cash Flow Information Nine months ended September 30, (in millions) 2024 2023 Transfers from available-for-sale debt securities to held-to-maturity debt securities $ — 3,687 Transfers from held-to-maturity debt securities to available-for-sale debt securities (1) — 23,919 Reclassification of long-term debt to accrued expenses and other liabilities (2) 4,927 — (1) In first quarter 2023, we reclassified HTM debt securities to AFS debt securities in connection with the adoption of ASU 2022-01, Derivatives and Hedging (Topic 815): Fair Value Hedging – Portfolio Layer Method . For additional information, see Note 1 (Summary of Significant Accounting Policies) in our 2023 Form 10-K. (2) Effective January 1, 2024, we reclassified unfunded commitment liabilities for affordable housing investments from Long-term debt to Accrued expenses and other liabilities in connection with the adoption of ASU 2023-02. Subsequent Events We have evaluated the effects of events that have occurred subsequent to September 30, 2024, and there have been no material events that would require recognition in our third quarter 2024 consolidated financial statements or disclosure in the Notes to the consolidated financial statements.

(2) Realized gains and losses relate to AFS debt securities. There were no realized gains or losses from HTM debt securities in all periods presented. 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 ACL for debt securities. 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 (NRSROs). Debt securities rated investment grade, that is those with ratings similar to BBB-/Baa3 or above, as defined by NRSROs, 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 NRSROs, 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. Substantially all of our debt securities were rated by NRSROs at September 30, 2024, and December 31, 2023. Table 3.4 shows the percentage of fair value of AFS debt securities and amortized cost of HTM debt securities determined to be rated investment grade, inclusive of securities rated based on internal credit grades. Table 3.4: Investment Grade Debt Securities Available-for-Sale Held-to-Maturity ($ in millions) Fair value % investment grade Amortized cost % investment grade September 30, 2024 Total portfolio (1) $ 166,004 99 % $ 243,240 99 % Breakdown by category: Securities of U.S. Treasury and federal agencies (2) $ 149,048 100 % $ 201,516 100 % Securities of U.S. states and political subdivisions 12,652 99 18,331 100 Collateralized loan obligations (3) 1,725 100 20,326 100 All other debt securities (4) 2,579 92 3,067 64 December 31, 2023 Total portfolio (1) $ 130,448 99 % $ 262,801 99 % Breakdown by category: Securities of U.S. Treasury and federal agencies (2) $ 105,045 100 % $ 212,960 100 % Securities of U.S. states and political subdivisions 20,066 99 18,635 100 Collateralized loan obligations (3) 1,533 100 28,154 100 All other debt securities (4) 3,804 95 3,052 64 (1) 99% were rated AA- and above at both September 30, 2024, and December 31, 2023. (2) Includes federal agency mortgage-backed securities. (3) 100% were rated AA- and above at both September 30, 2024, and December 31, 2023. (4) Includes non-U.S. government, non-agency mortgage-backed, 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. Debt securities that are past due and still accruing or in nonaccrual status were insignificant at both September 30, 2024, and December 31, 2023. Net charge-offs on debt securities were insignificant in the third quarter and first nine months of both 2024 and 2023. Unrealized Losses of Available-for-Sale Debt Securities Table 3.5 shows the gross unrealized losses and fair value of AFS debt securities by length of time those individual securities in each category have been in a continuous loss position. 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 amortized cost basis, net of the allowance for credit losses.

We have assessed each debt security with gross unrealized losses included in the previous table for credit impairment. 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. Credit impairment is recorded as an ACL for debt securities. 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) in our 2023 Form 10-K. Contractual Maturities Table 3.6 and Table 3.7 show the remaining contractual maturities of AFS and HTM debt securities, respectively.

Loans and Related Allowance for Credit Losses	Note 5: Loans and Related Allowance for Credit Losses Table 5.1 presents total loans outstanding by portfolio segment and class of financing receivable. Loans are reported at their outstanding principal balances net of any unearned income, cumulative charge-offs, unamortized deferred fees and costs on originated loans, and unamortized premiums or discounts on purchased loans. These amounts were less than 1% of our total loans outstanding at both September 30, 2024, and December 31, 2023. Outstanding balances exclude accrued interest receivable on loans, except for certain revolving loans, such as credit card loans. See Note 7 (Intangible Assets and Other Assets) for additional information on accrued interest receivable. Amounts considered to be uncollectible are reversed through interest income. During the first nine months of 2024, we reversed accrued interest receivable of $33 million for our commercial portfolio segment and $300 million for our consumer portfolio segment, compared with $31 million and $188 million, respectively, for the same period a year ago.

Our non-U.S. loans are reported by respective class of financing receivable in the table above. Substantially all of our non-U.S. loan portfolio is commercial loans. Table 5.2 presents total non-U.S. commercial loans outstanding by class of financing receivable.

The table excludes loans for which we have elected the fair value option and government insured/guaranteed loans because their loan activity normally does not impact the ACL.

Our commercial lending commitments include, but are not limited to, (i) commitments for working capital and general corporate purposes, (ii) financing to customers who warehouse financial assets secured by real estate, consumer, or corporate loans, (iii) financing that is expected to be syndicated or replaced with other forms of long-term financing, and (iv) commercial real estate lending. We also originate multipurpose lending commitments under which commercial customers have the option to draw on the facility in one of several forms, including the issuance of letters of credit, which reduces the unfunded commitment amounts of the facility. The maximum credit risk for these commitments will generally be lower than the contractual amount because these commitments may expire without being used or may be cancelled at the customer’s request. We may reduce or cancel lines of credit in accordance with the contracts and applicable law. Our credit risk monitoring activities include managing the amount of commitments, both to individual customers and in total, and the size and maturity structure of these commitments. We do not recognize an ACL for commitments that are unconditionally cancellable at our discretion. We issue commercial letters of credit to assist customers in purchasing goods or services, typically for international trade. At September 30, 2024, and December 31, 2023, we had $1.3 billion and $1.1 billion, respectively, of outstanding issued commercial letters of credit. See Note 14 (Guarantees and Other Commitments) for additional information on issued standby letters of credit. We may be a fronting bank, whereby we act as a representative for other lenders, and 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 contractual amount of our unfunded credit commitments, including unissued letters of credit, is summarized in Table 5.4. The table is presented net of commitments syndicated to others, including the fronting arrangements described above, and excludes issued letters of credit and discretionary amounts where our approval or consent is required prior to any loan funding or commitment increase.

Allowance for Credit Losses Table 5.5 presents the ACL for loans, which consists of the allowance for loan losses and the allowance for unfunded credit commitments. The ACL for loans decreased $349 million from December 31, 2023, reflecting decreases for auto loans, commercial real estate loans, and residential mortgage loans, partially offset by increases for credit card loans.

For additional information, see Note 1 (Summary of Significant Accounting Policies) to Financial Statements in our 2023 Form 10-K. Credit Quality We monitor credit quality by evaluating various attributes and utilize such information in our evaluation of the appropriateness of the ACL for loans. 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. COMMERCIAL CREDIT QUALITY INDICATORS We manage a consistent process for assessing commercial loan credit quality. Commercial loans are generally 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 regulatory definitions of pass and criticized categories with the criticized segmented among special mention, substandard, doubtful, and loss categories. Table 5.7 provides the outstanding balances of our commercial loan portfolio by risk category and credit quality information by origination year 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 for a borrower experiencing financial difficulty.

Loan delinquency, Fair Isaac Corporation (FICO) credit scores and loan-to-value (LTV) for residential mortgage loans are the primary credit quality indicators that we monitor and utilize in our evaluation of the appropriateness of the ACL for the consumer loan portfolio segment. Many of our loss estimation techniques used for the ACL for loans rely on delinquency-based models; therefore, delinquency is an important indicator of credit quality in the establishment of our ACL for consumer loans. 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). FICO scores are not available for certain loan types or may not be required if we deem it unnecessary due to strong collateral and other borrower attributes. LTV is the ratio of the outstanding loan balance divided by the property collateral value. For junior lien mortgages, we use the total combined loan balance of first and junior lien mortgages (including unused line of credit amounts). We obtain LTVs 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 $1.5 million or more, as the AVM values have proven less accurate for these properties. Generally, we update LTVs on a quarterly basis. Certain loans do not have an LTV due to a lack of industry data availability and portfolios acquired from or serviced by other institutions. Gross charge-offs by loan class are included in the following tables for the nine months ended September 30, 2024, and year ended December 31, 2023, which we monitor as part of our credit risk management practices; however, charge-offs are not a primary credit quality indicator for our loan portfolio. 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 for a borrower experiencing financial difficulty. Table 5.9 provides the outstanding balances of our residential mortgage loans by our primary credit quality indicators.

LOANS IN PROCESS OF FORECLOSURE Our recorded investment in consumer mortgage loans collateralized by residential real estate property that are in process of foreclosure was $693 million and $837 million at September 30, 2024, and December 31, 2023, respectively, which included $537 million and $660 million, respectively, of loans that are government insured/guaranteed. Under the Consumer Financial Protection Bureau guidelines, we do not commence the foreclosure process on residential mortgage loans until after the loan is 120 days delinquent. Foreclosure procedures and timelines vary depending on whether the property address resides in a judicial or non-judicial state. Judicial states require the foreclosure to be processed through the state’s courts while non-judicial states are processed without court intervention. Foreclosure timelines vary according to state law. LOANS 90 DAYS OR MORE PAST DUE AND STILL ACCRUING Certain loans 90 days or more past due are still accruing, because they are (1) well-secured and in the process of collection or (2) residential mortgage or consumer loans exempt under regulatory rules from being classified as nonaccrual until later delinquency, usually 120 days past due. Table 5.14 shows loans 90 days or more past due and still accruing by class for loans not government insured/guaranteed.

The following disclosures were added on a prospective basis as a result of our adoption of ASU 2022-02, Financial Instruments-Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures, on January 1, 2023. These disclosures provide information on loan modifications in the form of principal forgiveness, interest rate reductions, other-than-insignificant (e.g., greater than three months) payment delays, term extensions or a combination of these modifications, as well as the financial effects of these modifications, and loan performance in the twelve months following the modification. Loans that both modify and are paid off or charged-off during the period are not included in the disclosures below. These disclosures do not include loans discharged by a bankruptcy court as the only concession, which were insignificant for the third quarter and first nine months of both 2024 and 2023. For additional information on our loan modifications to borrowers experiencing financial difficulty, see Note 5 (Loans and Related Allowance for Credit Losses) in our 2023 Form 10-K. Table 5.15 presents the outstanding balance of modified commercial loans and the related financial effects of these modifications.

Commercial loans that received a modification in the past 12 months as of September 30, 2024, and subsequently defaulted in the third quarter and first nine months of 2024, were insignificant. Commercial loans that received a modification in the third quarter and first nine months of 2023, and subsequently defaulted in the same period were insignificant. Table 5.16 provides past due information as of September 30, 2024, for commercial loans that received a modification in the past 12 months and past due information as of September 30, 2023, for commercial loans that received a modification in the first nine months of 2023. For loan modifications that include a payment deferral, payment performance is not included in the table below until the loan exits the deferral period and payments resume. The table also includes the amount of gross charge-offs that occurred on these modifications during the third quarter and first nine months of both 2024 and 2023.

Mortgage Banking Activities [Abstract]
Mortgage Banking Activities	Note 6: Mortgage Banking Activities Mortgage banking activities consist of residential and commercial mortgage originations, sales and servicing. We apply the fair value method to residential mortgage servicing rights (MSRs) and apply the amortization method to commercial MSRs. Table 6.1 presents MSRs, including the changes in MSRs measured using the fair value method and the amortization method. Table 6.1: Mortgage Servicing Rights Quarter ended September 30, Nine months ended September 30, (in millions) 2024 2023 2024 2023 Residential MSRs at fair value, beginning of period $ 7,061 8,251 $ 7,468 9,310 Originations/purchases 22 36 61 131 Sales and other (10) (51) (307) (650) Net additions 12 (15) (246) (519) Changes in fair value: Due to valuation inputs or assumptions: Market interest rates (1) (296) 562 71 699 Servicing and foreclosure costs (22) (11) (51) (9) Discount rates — (20) (53) (45) Prepayment estimates and other (2) 24 (20) 50 (43) Net changes in valuation inputs or assumptions (294) 511 17 602 Changes due to collection/realization of expected cash flows (3) (235) (290) (695) (936) Total changes in fair value (529) 221 (678) (334) Residential MSRs at fair value, end of period 6,544 8,457 6,544 8,457 Commercial MSRs at amortized cost, end of period (4) 949 1,069 949 1,069 Total MSRs $ 7,493 9,526 $ 7,493 9,526 (1) Includes prepayment rate changes due to changes in market interest rates. Residential MSRs are economically hedged with derivative instruments to reduce exposure to changes in market interest rates. (2) Represents other changes in valuation model inputs or assumptions, including prepayment rate estimation changes that are independent of mortgage interest rate changes. (3) Represents the reduction in the residential MSR fair value for the cash flows expected to be collected during the period, net of income accreted due to the passage of time. (4) The estimated fair value of commercial MSRs was $1.4 billion and $1.9 billion, at September 30, 2024 and 2023, respectively. Table 6.2 provides key weighted-average assumptions used in the valuation of residential MSRs and sensitivity of the current fair value of residential MSRs to immediate adverse changes in those assumptions. See Note 12 (Fair Values of Assets and Liabilities) for additional information on key assumptions for residential MSRs. Table 6.2: Assumptions and Sensitivity of Residential MSRs ($ in millions, except cost to service amounts) Sep 30, 2024 Dec 31, 2023 Fair value of interests held $ 6,544 7,468 Expected weighted-average life (in years) 6.3 6.3 Key assumptions: Prepayment rate assumption (1) 8.5 % 8.9 Impact on fair value from 10% adverse change $ (196) (224) Impact on fair value from 25% adverse change (472) (538) Discount rate assumption 9.6 % 9.4 Impact on fair value from 100 basis point increase $ (259) (294) Impact on fair value from 200 basis point increase (498) (565) Cost to service assumption ($ per loan) 104 105 Impact on fair value from 10% adverse change (138) (148) Impact on fair value from 25% adverse change (345) (369) (1) Includes a blend of prepayment speeds and expected defaults. Prepayment speeds are influenced by mortgage interest rates as well as our estimation of drivers of borrower behavior. The sensitivities in the preceding 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, which might magnify or counteract the sensitivities. We present information for our managed servicing portfolio in Table 6.3 using unpaid principal balance for loans serviced and subserviced for others and carrying 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. The credit risk related to these advances is limited since the reimbursement is generally senior to cash payments to investors and are generally reimbursed within a short timeframe from cash flows from the trust, government- sponsored enterprise (GSEs), insurer, or 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. We also advance payments of taxes and insurance for our owned loans which are collectible from the borrower. Servicing advances on owned loans are written-off when deemed uncollectible.

Outstanding preferred shares rank senior to common shares both as to the payment of dividends and liquidation preferences but have no general voting rights. All outstanding preferred stock with a liquidation preference value, except for Series L Preferred Stock, may be redeemed for the liquidation preference value, plus any accrued but unpaid dividends, on any dividend payment date on or after the earliest redemption date for that series. Additionally, these same series of preferred stock may be redeemed following a “regulatory capital treatment event,” as described in the terms of each series. Capital actions, including redemptions of our preferred stock, may be subject to regulatory approval or conditions. In addition, we are authorized to issue 4 million shares of preference stock, without par value. We have not issued any preference shares under this authorization.

Legal Actions

Legal Actions	9 Months Ended
	Sep. 30, 2024
Commitments and Contingencies Disclosure [Abstract]
Legal Actions	Note 10: 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 or other adverse consequences. 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 to or otherwise cooperate with government authorities in the conduct of investigations of other persons or industry groups. 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. There can be no assurance as to the ultimate outcome of legal actions, including the matters described below, and the actual costs of resolving legal actions may be substantially higher or lower than the amounts accrued for those actions. ADVISORY ACCOUNT CASH SWEEP MATTERS The United States Securities and Exchange Commission (SEC) has undertaken an investigation regarding the cash sweep options that the Company provides to investment advisory clients at account opening. The Company is in resolution discussions with the SEC, although there can be no assurance as to the outcome of these discussions. In addition, putative class actions have been filed in federal district courts alleging that the Company breached its fiduciary duties or agreements with regard to rates paid to clients in its cash sweep program. ANTI-MONEY LAUNDERING AND ECONOMIC SANCTIONS RELATED INVESTIGATIONS Government authorities are conducting inquiries or investigations regarding issues related to the Company’s anti-money laundering and sanctions programs. On September 12, 2024, the Company announced that Wells Fargo Bank, N.A. entered into a formal agreement with the Office of the Comptroller of the Currency (OCC) related to the bank’s anti-money laundering and sanctions risk management practices. COMPANY 401(K) PLAN LITIGATION On September 26, 2022, participants in the Company’s 401(k) plan filed a putative class action in the United States District Court for the District of Minnesota alleging that the Company violated the Employee Retirement Income Security Act of 1974 in connection with certain transactions associated with the Employee Stock Ownership Plan feature of the Company’s 401(k) plan, including the manner in which the 401(k) plan purchased certain securities used in connection with the Company’s contributions to the 401(k) plan. HIRING PRACTICES MATTERS Government agencies, including the United States Department of Justice and the SEC, have undertaken formal or informal inquiries or investigations regarding the Company’s hiring practices related to diversity. The United States Department of Justice and the SEC have since closed their investigations without taking action. A putative securities fraud class action has also been filed in the United States District Court for the Northern District of California alleging that the Company and certain of its executive officers made false or misleading statements about the Company’s hiring practices related to diversity. Allegations related to the Company’s hiring practices related to diversity are also among the subjects of a shareholder derivative lawsuit pending in the United States District Court for the Northern District of California. HOME MORTGAGE DISCRIMINATION LITIGATION Plaintiffs representing a class of home mortgage applicants and customers filed putative class actions against Wells Fargo alleging that Wells Fargo’s mortgage lending policies and practices resulted in disparate treatment and disparate impact against minority applicants. These actions have been consolidated in the United States District Court for the Northern District of California. INTERCHANGE LITIGATION Plaintiffs representing a class of merchants have filed putative class actions, and individual merchants have filed individual actions, alleging that Visa and Mastercard, as well as certain payment card issuing banks including Wells Fargo, unlawfully colluded to set interchange rates associated with Visa and Mastercard payment card transactions and that enforcement of certain Visa and Mastercard rules and alleged tying and bundling of services offered to merchants were anticompetitive. These actions have been consolidated in the United States District Court for the Eastern District of New York. Wells Fargo, 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 or judgments from the relevant litigation. In July 2012, Visa, Mastercard, and the financial institution defendants, including Wells Fargo, agreed to pay a total of approximately $6.6 billion in order to settle the consolidated action. Several merchants opted out of the settlement and are pursuing individual actions. In June 2016, the United States Court of Appeals for the Second Circuit vacated the settlement agreement and reversed and remanded the consolidated action to the district court for further proceedings. In November 2016, the district court appointed lead class counsel for a damages class and an equitable relief class. The parties entered into a settlement agreement to resolve the damages class claims pursuant to which defendants agreed to pay a total of approximately $6.2 billion, which includes approximately $5.3 billion of funds remaining in escrow from the 2012 settlement and $900 million in additional funding. Wells Fargo’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 affirmed by the Second Circuit on March 15, 2023. On September 27, 2021, the district court granted the plaintiffs’ motion for class certification in the equitable relief case. On March 26, 2024, Visa and Mastercard entered into a settlement agreement to resolve the equitable relief class claims, which was denied by the district court on June 25, 2024. Some of the opt-out and direct-action cases have been settled while others remain pending. RMBS TRUSTEE LITIGATION In December 2014, Phoenix Light SF Limited (Phoenix Light) and certain related entities filed a complaint in the United States District Court for the Southern District of New York alleging claims against Wells Fargo Bank, N.A., in its capacity as trustee for a number of residential mortgage-backed securities (RMBS) trusts. Complaints raising similar allegations have been filed by Commerzbank AG in the Southern District of New York, IKB International and IKB Deutsche Industriebank (together, IKB) in New York state court, and Park Royal I LLC and Park Royal II LLC in New York state court. In each case, the plaintiffs allege that Wells Fargo Bank, N.A., as trustee, caused losses to investors, and plaintiffs assert 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. In July 2022, the district court dismissed Phoenix Light’s claims and certain of the claims asserted by Commerzbank AG, and subsequently entered judgment in each case in favor of Wells Fargo Bank, N.A. In August 2022, Phoenix Light and Commerzbank AG each appealed the district court’s decision to the United States Court of Appeals for the Second Circuit. Phoenix Light dismissed its appeal in May 2023, terminating its case. In October 2024, the Second Circuit denied Commerzbank AG’s appeal. In November 2023, the Company entered into an agreement with IKB to resolve IKB’s claims. The Company previously settled two class actions filed by institutional investors and an action filed by the National Credit Union Administration with similar allegations. 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. ZELLE INVESTIGATION The Consumer Financial Protection Bureau has been conducting an investigation regarding the handling of customer disputes related to fund transfers made through the Zelle Network. 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 losses in excess of the Company’s accrual for probable and estimable losses was approximately $2.0 billion as of September 30, 2024. 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. Based on information currently available, advice of counsel, available insurance coverage, and established reserves, Wells Fargo believes that the eventual outcome of the 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 11: 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 purposes. For additional information on our derivative activities, see Note 14 (Derivatives) in our 2023 Form 10-K. Table 11.1 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 our consolidated 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 derivative cash flows are determined.

Where legally enforceable, these master netting arrangements give the ability, in the event of default by the counterparty, to liquidate securities held as collateral and to offset receivables and payables with the same counterparty. We reflect all derivative balances and related cash collateral subject to enforceable master netting arrangements on a net basis on our consolidated balance sheet. We do not net non-cash collateral that we receive or pledge against derivative balances on our consolidated balance sheet. For disclosure purposes, we present “Total Derivatives, net” which represents the aggregate of our net exposure to each counterparty after considering the balance sheet netting adjustments and any non-cash collateral. 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. Table 11.2 provides information on the fair values of derivative assets and liabilities subject to enforceable master netting arrangements, the balance sheet netting adjustments and the resulting net fair value amount recorded on our consolidated balance sheet, as well as the non-cash collateral associated with such arrangements. 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 15 (Securities and Other Collateralized Financing Activities).

Counterparty valuation adjustments related to derivative assets were $299 million and $292 million and debit valuation adjustments related to derivative liabilities were $215 million and $222 million as of September 30, 2024, and December 31, 2023, respectively, and were primarily related to interest rate contracts. 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. We also enter into futures contracts, forward contracts, and swap contracts to hedge our exposure to the price risk of physical commodities included in other assets on our consolidated balance sheet. 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 AFS debt securities due to changes in interest rates, foreign currency rates, or both. For certain fair value hedges of interest rate risk, we use the portfolio layer method to hedge stated amounts of closed portfolios of AFS debt securities. 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 (OCI). See Note 21 (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 interest-earning deposits with banks and certain floating-rate commercial loans. 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 $359 million pre-tax of deferred net losses related to cash flow hedges in OCI at September 30, 2024, will be reclassified into net interest income during the next twelve months. For cash flow hedges as of September 30, 2024, we are hedging our interest rate and foreign currency exposure to the variability of future cash flows for all forecasted transactions for a maximum of approximately 8 years. For additional information on our accounting hedges, see Note 1 (Summary of Significant Accounting Policies) in our 2023 Form 10-K.

(3) The balance includes $618 million and $731 million of long-term debt cumulative basis adjustments as of September 30, 2024, and December 31, 2023, respectively, on terminated hedges whereby the hedged items have subsequently been re-designated into existing hedges. (4) Carrying amount represents the amortized cost. (5) The balance includes cumulative basis adjustments of $58 million and $(46) million as of September 30, 2024, and December 31, 2023, respectively, related to certain AFS debt securities designated as the hedged item in a fair value hedge using the portfolio layer method. At September 30, 2024, the aggregated designated hedged items using the portfolio layer method had a carrying amount of $16.3 billion from closed portfolios of financial assets totaling $16.3 billion. At December 31, 2023, the aggregated designated hedged items using the portfolio layer method had a carrying amount of $25.8 billion from closed portfolios of financial assets totaling $28.2 billion. (6) Other assets consists of hedged physical commodity inventory. 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. For additional information on economic hedges and other derivatives, see Note 14 (Derivatives) in our 2023 Form 10-K. Table 11.6 shows the net gains (losses) related to derivatives not designated as hedging instruments. Gains (losses) on customer accommodation trading derivatives are excluded from the following table. For additional information, see Note 2 (Trading Activities). Table 11.6: Gains (Losses) on Derivatives Not Designated as Hedging Instruments Quarter ended September 30, Nine months ended September 30, (in millions) 2024 2023 2024 2023 Interest rate contracts (1) $ 392 (788) $ (37) (945) Equity contracts (2) 27 (300) 153 (281) Foreign exchange contracts (3) (649) 337 (481) (356) Credit contracts (4) — 5 8 4 Net gains (losses) recognized related to derivatives not designated as hedging instruments $ (230) (746) $ (357) (1,578) (1) Derivative gains and (losses) related to mortgage banking activities were recorded in mortgage banking noninterest income.

For additional information on our mortgage banking interest rate contracts, see Note 6 (Mortgage Banking Activities). (2) Includes derivative gains and (losses) used to economically hedge the deferred compensation plan, which were recorded in personnel noninterest expense, and derivative instruments related to our previous sales of shares of Visa Inc. Class B common stock, which were recorded in other noninterest income. (3) Includes derivatives used to mitigate foreign exchange risk of specified foreign currency-denominated assets and liabilities. In 2024, gains and (losses) were recorded in net gains from trading and securities within noninterest income. Prior to 2024, gains and (losses) were recorded in other noninterest income. (4) Includes credit derivatives used to mitigate credit risk associated with lending exposure. Gains and (losses) were recorded in other noninterest income. 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 generally use credit derivatives to assist customers with their risk management objectives by purchasing and selling credit protection on corporate debt obligations through the use of credit default swaps or through risk participation swaps to help manage counterparty exposure. We would be required to perform under the credit derivatives we sold 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. Table 11.7 provides details of sold credit derivatives. Table 11.7: Sold Credit Derivatives Notional amount (in millions) Protection sold Protection sold – non-investment grade September 30, 2024 Credit default swaps $ 12,569 1,282 Risk participation swaps 5,993 3,787 Total credit derivatives $ 18,562 5,069 December 31, 2023 Credit default swaps $ 18,453 1,399 Risk participation swaps 6,632 6,485 Total credit derivatives $ 25,085 7,884 Protection sold represents the estimated maximum exposure to loss that would be incurred if, upon an event of default, the value of our interests and any associated collateral declined to zero, and does not take into consideration any recovery value from the referenced obligation or offset from collateral held or any economic hedges. 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 credit risk to be low if the underlying assets under the credit derivative have an external rating that is investment grade. If an external rating is not available, we classify the credit derivative as non-investment grade. Our maximum exposure to sold credit derivatives is managed through posted collateral and purchased credit derivatives with identical or similar reference positions in order to achieve our desired credit risk profile. The credit risk management is designed to provide an ability to recover a significant portion of any amounts that would be paid under sold credit derivatives. 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 11.8 illustrates our exposure to OTC bilateral derivative contracts 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 12: Fair Values of Assets and Liabilities We use fair value measurements to record fair value adjustments to certain assets and liabilities and to fulfill fair value disclosure requirements. Assets and liabilities recorded at fair value on a recurring basis, such as derivatives, residential MSRs, and trading or AFS debt securities, are presented in Table 12.1 in this Note. Additionally, from time to time, we record fair value adjustments on a nonrecurring basis. These nonrecurring adjustments typically involve application of lower of cost or fair value (LOCOM) accounting, write-downs of individual assets or application of the measurement alternative for nonmarketable equity securities. Assets recorded at fair value on a nonrecurring basis are presented in Table 12.4 in this Note. We provide in Table 12.9 estimates of fair value for financial instruments that are not recorded at fair value, such as loans and debt liabilities carried at amortized cost. See Note 1 (Summary of Significant Accounting Policies) in our 2023 Form 10-K for a 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, see Note 15 ( Fair Values of Assets and Liabilities) in our 2023 Form 10-K. FAIR VALUE HIERARCHY We classify our assets and liabilities recorded at fair value as either Level 1, 2, or 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 2023 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. This determination is ultimately based upon the specific facts and circumstances of each instrument or instrument category and judgments are made regarding the significance of the unobservable inputs to the instruments’ fair value measurement in its entirety. If unobservable inputs are considered significant, the instrument is classified as Level 3. We do not classify nonmarketable equity securities in the fair value hierarchy if we use the non-published net asset value (NAV) per share (or its equivalent) as a practical expedient to measure fair value. Marketable equity securities with published NAVs are classified in the fair value hierarchy.

Table 12.3 provides quantitative information about the valuation techniques and significant unobservable inputs used in the valuation of our Level 3 assets and liabilities measured at fair value on a recurring basis. The significant unobservable inputs for Level 3 assets 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 (for additional information on vendor-developed valuations, see Note 15 (Fair Values of Assets and Liabilities) in our 2023 Form 10-K). 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.

For additional information on the valuation techniques and significant unobservable inputs used in the valuation of our Level 3 assets and liabilities, including how changes in these inputs affect fair value estimates, see Note 15 (Fair Values of Assets and Liabilities) in our 2023 Form 10-K. Assets and Liabilities Recorded at Fair Value on a Nonrecurring Basis We may be required, from time to time, to measure certain assets at fair value on a nonrecurring basis in accordance with GAAP. These adjustments to fair value usually result from application of LOCOM accounting, write-downs of individual assets, or application of the measurement alternative for certain nonmarketable equity securities. Table 12.4 provides the fair value hierarchy and fair value at the date of the nonrecurring fair value adjustment for all assets that were still held as of September 30, 2024, and December 31, 2023, and for which a nonrecurring fair value adjustment was recorded during the nine months ended September 30, 2024, and the year ended December 31, 2023.

Table 12.6 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 and determined 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 equity securities and venture capital and private equity investments in consolidated portfolio companies.

Fair Value Option The fair value option is an irrevocable election, generally only permitted upon initial recognition of financial assets or liabilities, to measure eligible financial instruments at fair value with changes in fair value reflected in earnings. We may elect the fair value option to align the measurement model with how the financial assets or liabilities are managed or to reduce complexity or accounting asymmetry. Following is a discussion of the portfolios for which we elected the fair value option. For additional information, including the basis for our fair value option elections, see Note 15 (Fair Values of Assets and Liabilities) in our 2023 Form 10-K. Table 12.7 reflects differences between the fair value carrying amount of the assets and liabilities for which we have elected the fair value option and the contractual aggregate unpaid principal amount at maturity.

Table 12.8 reflects amounts included in earnings related to initial measurement and subsequent changes in fair value, by income statement line item, for assets and liabilities for which the fair value option was elected. Amounts recorded in net interest income are excluded from the table below. Table 12.8: Gains (Losses) on Changes in Fair Value Included in Earnings 2024 2023 (in millions) Mortgage banking noninterest income Net gains from trading and securities Other noninterest income Mortgage banking noninterest income Net gains from trading and securities Other noninterest income Quarter ended September 30, Loans held for sale $ 65 13 — 30 8 (44) Interest-bearing deposits — (6) — — (4) — Long-term debt — (56) — — 10 — Nine months ended September 30, Loans held for sale $ 108 28 — 161 33 (48) Interest-bearing deposits — (2) — — (4) — Long-term debt — 3 — — (11) — For performing loans, instrument-specific credit risk gains or losses are derived principally by determining the change in fair value of the loans due to changes in the observable or implied credit spread. Credit spread is the market yield on the loans less the relevant risk-free benchmark interest rate. For nonperforming loans, we attribute all changes in fair value to instrument-specific credit risk. For LHFS accounted for under the fair value option, instrument-specific credit gains or losses were insignificant during the third quarter and first nine months of both 2024 and 2023. For interest-bearing deposits and long-term debt, instrument-specific credit risk gains or losses represent the impact of changes in fair value due to changes in our credit spread and are generally derived using observable secondary bond market information. These impacts are recorded within the debit valuation adjustments (DVA) in OCI. See Note 21 (Other Comprehensive Income) for additional information. Disclosures about Fair Value of Financial Instruments Table 12.9 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 the scope of this table, such as certain insurance contracts, certain nonmarketable equity securities, 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 12.9. 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 $505 million and $575 million at September 30, 2024, and December 31, 2023, respectively. The total of the fair value calculations presented does not represent, and should not be construed to represent, the underlying fair value of the Company.

Securitizations and Variable Interest Entities [Abstract]
Securitizations and Variable Interest Entities	Note 13: Securitizations and Variable Interest Entities Involvement with Variable Interest Entities (VIEs) In the normal course of business, we enter into various types of on- and off-balance sheet transactions with special purpose entities (SPEs), which are corporations, trusts, limited liability companies or partnerships that are established for a limited purpose. SPEs are often formed in connection with securitization transactions whereby financial assets are transferred to an SPE. SPEs formed in connection with securitization transactions are generally considered variable interest entities (VIEs). The VIE may alter the risk profile of the asset by entering into derivative transactions or obtaining credit support, and issues various forms of interests in those assets to investors. When we transfer financial assets from our consolidated balance sheet to a VIE in connection with a securitization, we typically receive cash and sometimes other interests in the VIE as proceeds for the assets we transfer. In certain transactions with VIEs, we may retain the right to service the transferred assets and repurchase the transferred assets if the outstanding balance of the assets falls below the level at which the cost to service the assets exceed the benefits. In addition, we may purchase the right to service loans transferred to a VIE by a third party. In connection with our securitization or other VIE activities, we have various forms of ongoing involvement with VIEs, which may include: • underwriting securities issued by VIEs and subsequently making markets in those securities; • providing credit enhancement on securities issued by VIEs through the use of letters of credit or financial guarantees; • entering into other derivative contracts with VIEs; • holding senior or subordinated interests in VIEs; • acting as servicer or investment manager for VIEs; • providing administrative or trustee services to VIEs; and • providing seller financing to VIEs. 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. MORTGAGE LOANS SOLD TO GOVERNMENT SPONSORED ENTERPRISES AND TRANSACTIONS WITH GINNIE MAE In the normal course of business we sell residential and commercial mortgage loans to GSEs. These loans are generally transferred into securitizations sponsored by the GSEs, which provide certain credit guarantees to investors and servicers. We also transfer mortgage loans into securitization pools pursuant to Government National Mortgage Association (GNMA) guidelines which are insured by the FHA or guaranteed by the VA. Mortgage loans eligible for securitization with the GSEs or GNMA are considered conforming loans. The GSEs or GNMA design the structure of these securitizations, sponsor the involved VIEs, and have power over the activities most significant to the VIE. We account for loans transferred in conforming mortgage loan securitization transactions as sales and do not consolidate the VIEs as we are not the primary beneficiary. In exchange for the transfer of loans, we typically receive securities issued by the VIEs which we sell to third parties for cash or hold for investment purposes as HTM or AFS securities. We also retain servicing rights on the transferred loans. As a servicer, we retain the option to repurchase loans from certain loan securitizations, which becomes exercisable based on delinquency status such as when three scheduled loan payments are past due. When we have the unilateral option to repurchase a loan, we recognize the loan and a corresponding liability on our balance sheet regardless of our intent to repurchase the loan, and the loans remain pledged to the securitization. At September 30, 2024, and December 31, 2023, we recorded assets and related liabilities of $1.3 billion and $1.0 billion, respectively, where we did not exercise our option to repurchase eligible loans. We repurchased loans of $14 million and $122 million, during the third quarter and first nine months of 2024, respectively, and $49 million and $240 million during the third quarter and first nine months of 2023, respectively. Upon transfers of loans, we also provide indemnification for losses incurred due to material breaches of contractual representations and warranties as well as other recourse arrangements. At September 30, 2024, and December 31, 2023, our liability for these repurchase and recourse arrangements was $194 million and $229 million, respectively, and the maximum exposure to loss was $13.7 billion and $13.6 billion at September 30, 2024, and December 31, 2023, respectively. Substantially all residential servicing activity is related to assets transferred to GSE and GNMA securitizations. See Note 6 (Mortgage Banking Activities) for additional information about residential and commercial servicing rights, advances and servicing fees. NONCONFORMING MORTGAGE LOAN SECURITIZATIONS In the normal course of business, we sell nonconforming mortgage loans in securitization transactions that we design and sponsor. Nonconforming mortgage loan securitizations do not involve a government credit guarantee, and accordingly, beneficial interest holders are subject to credit risk of the underlying assets held by the securitization VIE. We typically originate the transferred loans and account for the transfers as sales. We also typically retain the right to service the loans and may hold other beneficial interests issued by the VIE, such as debt securities held for investment purposes. Our servicing role related to nonconforming commercial mortgage loan securitizations is limited to primary or master servicer. We do not consolidate the VIE because the most significant decisions impacting the performance of the VIE are generally made by the special servicer or the controlling class security holder. For our residential nonconforming mortgage loan securitizations accounted for as sales, we either do not hold variable interests that we consider potentially significant or are not the primary servicer for a majority of the VIE assets. WHOLE LOAN SALE TRANSACTIONS We may also sell whole loans to VIEs where we have continuing involvement in the form of financing. We account for these transfers as sales, and do not consolidate the VIEs as we do not have the power to direct the most significant activities of the VIEs. Table 13.1 presents information about transfers of assets during the periods presented for which we recorded the transfers as sales and have continuing involvement with the transferred assets. In connection with these transfers, we received proceeds and recorded servicing assets and securities. Each of these interests are initially measured at fair value. Servicing rights are classified as Level 3 measurements, and generally securities are classified as Level 2. Transfers of residential mortgage loans are transactions with the GSEs or GNMA and generally result in no gain or loss because the loans are typically measured at fair value on a recurring basis. Transfers of commercial mortgage loans include both transactions with the GSEs or GNMA and nonconforming transactions. These commercial mortgage loans are carried at the lower of cost or market, and we recognize gains on such transfers when the market value is greater than the carrying value of the loan when it is sold.

(2) Represents assets or liabilities recognized at securitization settlement date related to our continuing involvement in the transferred assets. (3) Represents debt securities obtained at securitization settlement held for investment purposes that are classified as available-for-sale or held-to-maturity. Excludes trading debt securities held temporarily for market-marking purposes, which are sold to third parties at or shortly after securitization settlement, of $1.1 billion and $2.8 billion during the third quarter and first nine months of 2024, respectively, and $1.3 billion and $5.0 billion during the third quarter and first nine months of 2023, respectively. In the normal course of business, we purchase certain non-agency securities at initial securitization or subsequently in the secondary market, which we hold for investment. We also provide seller financing in the form of loans. We received cash flows of $82 million and $274 million during the third quarter and first nine months of 2024, respectively, and $58 million and $199 million during the third quarter and first nine months of 2023, respectively, related to principal and interest payments on these securities and loans, which exclude cash flows related to trading activities. Table 13.2 presents the key weighted-average assumptions we used to initially measure residential MSRs recognized during the periods presented. Table 13.2: Residential MSRs – Assumptions at Securitization Date 2024 2023 Quarter ended September 30, Prepayment rate (1) 19.9 % 16.0 Discount rate 9.9 9.9 Cost to service ($ per loan) $ 69 131 Nine months ended September 30, Prepayment rate (1) 18.1 % 17.2 Discount rate 10.1 9.7 Cost to service ($ per loan) $ 180 171 (1) Includes a blend of prepayment speeds and expected defaults. Prepayment speeds are influenced by mortgage interest rates as well as our estimation of drivers of borrower behavior. See Note 12 (Fair Values of Assets and Liabilities) and Note 6 (Mortgage Banking Activities) for additional information on key assumptions for residential MSRs. RESECURITIZATION ACTIVITIES We enter into resecuritization transactions as part of our trading activities to accommodate the investment and risk management activities of our customers. In resecuritization transactions, we transfer trading debt securities to VIEs in exchange for new beneficial interests that are sold to third parties at or shortly after securitization settlement. This activity is performed for customers seeking a specific return or risk profile. Substantially all of our transactions involve the resecuritization of conforming mortgage-backed securities issued by the GSEs or guaranteed by GNMA. We do not consolidate the resecuritization VIEs as we share in the decision-making power with third parties and do not hold significant economic interests in the VIEs other than for market-making activities. During the nine months ended September 30, 2024 and 2023, we transferred trading debt securities of $6.4 billion and $10.6 billion, respectively, to resecuritization VIEs, and retained trading debt securities of $418 million and $284 million, respectively. These amounts are not included in Table 13.1. As of September 30, 2024, and December 31, 2023, we held $711 million and $984 million of trading debt securities, respectively. Total resecuritization VIE assets, to which we sold assets and hold an interest, were $44.6 billion and $52.0 billion at September 30, 2024, and December 31, 2023, respectively. Total resecuritization VIE assets were $107.1 billion and $110.4 billion at September 30, 2024, and December 31, 2023, respectively. Sold or Securitized Loans Serviced for Others Table 13.3 presents information about loans that we have originated and sold or securitized in which we have ongoing involvement as servicer. For loans sold or securitized where servicing is our only form of continuing involvement, we generally experience a loss only 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. Table 13.3 excludes mortgage loans sold to and held or securitized by GSEs or GNMA of $538.1 billion and $592.5 billion at September 30, 2024, and December 31, 2023, respectively. Delinquent loans include loans 90 days or more past due and loans in bankruptcy, regardless of delinquency status. Delinquent loans and foreclosed assets related to loans sold to and held or securitized by GSEs and GNMA were $2.7 billion and $3.4 billion at September 30, 2024, and December 31, 2023, respectively. Table 13.3: Sold or Securitized Loans Serviced for Others Net charge-offs Total loans Delinquent loans Nine months ended September 30, (in millions) Sep 30, 2024 Dec 31, 2023 Sep 30, 2024 Dec 31, 2023 2024 2023 Commercial $ 70,999 67,232 1,304 1,000 53 89 Residential 7,747 8,311 337 393 7 12 Total off-balance sheet sold or securitized loans $ 78,746 75,543 1,641 1,393 60 101 (1) Includes $182 million and $163 million of commercial foreclosed assets and $18 million and $22 million of residential foreclosed assets at September 30, 2024, and December 31, 2023, respectively. Transactions with Unconsolidated VIEs MORTGAGE LOAN SECURITIZATIONS Table 13.4 includes nonconforming mortgage loan securitizations where we originate and transfer the loans to the unconsolidated securitization VIEs that we sponsor. For additional information about these VIEs, see the “Loan Sales and Securitization Activity” section within this Note. Nonconforming mortgage loan securitizations also include commercial mortgage loan securitizations sponsored by third parties where we did not originate or transfer the loans but serve as master servicer and invest in securities that could be potentially significant to the VIE. Conforming loan securitization and resecuritization transactions involving the GSEs and GNMA are excluded from Table 13.4 because we are not the sponsor or we do not have power over the activities most significant to the VIEs. Additionally, due to the nature of the guarantees provided by the GSEs and the FHA and VA, our credit risk associated with these VIEs is limited. For additional information about conforming mortgage loan securitizations and resecuritizations, see the “Loan Sales and Securitization Activity” and “Resecuritization Activities” sections within this Note. COMMERCIAL REAL ESTATE LOANS We may transfer purchased industrial development bonds and GSE credit enhancements to VIEs in exchange for beneficial interests. We may also acquire such beneficial interests in transactions where we do not act as a transferor. We own all of the beneficial interests and may also service the underlying mortgages that serve as collateral to the bonds. The GSEs have the power to direct the servicing and workout activities of the VIE in the event of a default, therefore we do not have control over the key decisions of the VIEs. OTHER VIE STRUCTURES We engage in various forms of structured finance arrangements with other VIEs, including asset-backed finance structures and other securitizations collateralized by asset classes other than mortgages. Collateral may include rental properties, asset-backed securities, student loans and mortgage loans. We may participate in structuring or marketing the arrangements as well as provide financing, service one or more of the underlying assets, or enter into derivatives with the VIEs. We may also receive fees for those services. We are not the primary beneficiary of these structures because we do not have power to direct the most significant activities of the VIEs. Table 13.4 provides a summary of our exposure to the unconsolidated VIEs described above, which includes investments in securities, loans, guarantees, liquidity agreements, commitments and certain derivatives. We exclude certain transactions with unconsolidated VIEs when our continuing involvement is temporary or administrative in nature or insignificant in size. In Table 13.4, “Total VIE assets” represents the remaining principal balance of assets held by unconsolidated VIEs using the most current information available. “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. Debt, guarantees and other commitments include amounts related to lending arrangements, liquidity agreements, and certain loss sharing obligations associated with loans originated, sold, and serviced under certain GSE programs. “Maximum exposure to loss” 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.

(2) All other assets includes mortgage servicing rights, derivative assets, and other assets (predominantly servicing advances). INVOLVEMENT WITH TAX CREDIT VIES In addition to the unconsolidated VIEs in Table 13.4, we may invest in or provide funding to affordable housing, renewable energy or similar projects that are designed to generate a return primarily through the realization of federal income tax credits and other income tax benefits. Our affordable housing investments generate low-income housing tax credits and our renewable energy investments generate either production tax credits, investment tax credits, or both. The projects are typically managed by third-party sponsors who have the power over the VIE’s assets; therefore, we do not consolidate the VIEs. The carrying value of our equity investments in tax credit VIEs was $21.0 billion and $19.7 billion at September 30, 2024, and December 31, 2023, respectively. Additionally, we had loans to tax credit VIEs with a carrying value of $2.0 billion and $2.1 billion at September 30, 2024, and December 31, 2023, respectively. Our maximum exposure to loss for tax credit VIEs at September 30, 2024, and December 31, 2023, was $29.0 billion and $30.6 billion, respectively. Our maximum exposure to loss included total unfunded equity and lending commitments of $6.1 billion and $8.7 billion at September 30, 2024, and December 31, 2023, respectively. Under these commitments, we are required to provide additional financial support during the investment period, at the discretion of project sponsors, or for certain renewable energy investments, on a contingent basis based on the amount of income tax credits earned. For equity investments accounted for using the proportional amortization method, a liability is recognized for unfunded commitments that are either legally binding or contingent but probable of funding. The liability recognized for these commitments at September 30, 2024, and December 31, 2023, was $6.7 billion and $4.9 billion, respectively. Substantially all of these commitments are expected to be funded within three years. See Note 1 (Summary of Significant Accounting Policies) for additional information on our adoption of ASU 2023-02 effective January 1, 2024, which impacted the accounting for our tax credit equity investments and related unfunded commitments. See also Note 14 (Guarantees and Other Commitments) for additional information about unrecognized commitments to purchase equity securities. Table 13.5 summarizes the impacts to our consolidated statement of income related to our affordable housing and renewable energy equity investments. Table 13.5: Income Statement Impacts for Affordable Housing and Renewable Energy Tax Credit Investments (1) Quarter ended September 30, Nine months ended September 30, (in millions) 2024 2023 2024 2023 Income (loss) before income tax expense (2) (A) $ 9 (98) $ (43) (468) Income tax expense (benefit): Proportional amortization of investments 539 417 2,403 1,312 Income tax credits and other income tax benefits (879) (827) (3,224) (2,571) Net expense (benefit) recognized within income tax expense (B) (340) (410) (821) (1,259) Net income related to affordable housing and renewable energy tax credit investments (A)-(B) $ 349 312 $ 778 791 (1) Amounts presented include the impacts for affordable housing and renewable energy tax credit investments, which are accounted for using either the proportional amortization method or the equity method. Prior period balances in this table do not reflect accounting changes related to our adoption of ASU 2023-02 , effective January 1, 2024. For additional information, see Note 1 (Summary of Significant Accounting Policies). (2) The balance predominantly relates to equity method losses from renewable energy tax credit investments, which are recorded in other noninterest income on our consolidated statement of income. Consolidated VIEs We consolidate VIEs where we are the primary beneficiary. We are the primary beneficiary of the following structure types: COMMERCIAL AND INDUSTRIAL LOANS AND LEASES We previously securitized dealer floor plan loans in a revolving master trust entity. As servicer and holder of all beneficial interests, we control the key decisions of the trust and consolidate the VIE. In first quarter 2024, we removed the loans held by the master trust entity by transferring them to another subsidiary of Wells Fargo, which had no impact on our consolidated balance sheet. In a separate transaction structure, we may provide the majority of debt and equity financing to an SPE that engages in lending and leasing to specific vendors and we service the underlying collateral. CREDIT CARD SECURITIZATIONS Beginning in first quarter 2024, we securitized a portion of our credit card loans to provide a source of funding. Credit card securitizations involve the transfer of credit card loans to a master trust that issues debt securities to third party investors that are collateralized by the transferred credit card loans. The underlying securitized credit card loans and other assets in the master trust are available only for payment of the debt securities issued by the master trust; they are not available to pay our other obligations. In addition, the investors in the debt securities do not have recourse to the general credit of Wells Fargo. We consolidate the master trust because, as the servicer of the credit card loans, we have the power to direct the activities that most significantly impact the economic performance and hold variable interests potentially significant to the VIE. We hold a minimum of 5% seller’s interest in the transferred credit card loans and we retain subordinated securities issued by the master trust, which collectively could result in exposure to potentially significant losses or benefits from the master trust. As of September 30, 2024, we held seller’s interest of $7.1 billion in the transferred credit card loans and subordinated securities of $750 million (at par) issued by the master trust, which are both eliminated in our consolidated financial statements. The transferred credit card loans and debt securities issued to third parties are recognized on our consolidated balance sheet, and classified as loans and long-term debt, respectively. Table 13.6 presents a summary of financial assets and liabilities of our consolidated VIEs. The carrying value represents assets and liabilities recognized on our consolidated balance sheet. “Total VIE assets” includes affiliate balances that are eliminated upon consolidation, and therefore in some instances will differ from the carrying value of assets. On our consolidated balance sheet, we separately disclose (1) the consolidated assets of certain VIEs that can only be used to settle the liabilities of those VIEs, and (2) the consolidated liabilities of certain VIEs for which the VIE creditors do not have recourse to Wells Fargo.

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. On our consolidated balance sheet, we reported the debt securities issued to the VIEs as long-term junior subordinated debt with a carrying value of $425 million and $414 million at September 30, 2024, and December 31, 2023, respectively.

Guarantees [Abstract]
Guarantees and Other Commitments	Note 14: Guarantees 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. For additional descriptions of our guarantees, see Note 17 (Guarantees and Other Commitments) in our 2023 Form 10-K. Table 14.1 shows carrying value and maximum exposure to loss on our guarantees. Table 14.1: Guarantees – Carrying Value and Maximum Exposure to Loss Maximum exposure to loss (in millions) Carrying value of obligation 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 September 30, 2024 Standby letters of credit (1) $ 92 15,165 4,997 2,188 13 22,363 7,837 Direct pay letters of credit (1) 6 1,746 1,382 56 118 3,302 782 Loans and LHFS sold with recourse 88 453 3,169 3,943 6,314 13,879 10,827 Exchange and clearing house guarantees — 33,446 — — — 33,446 — Other guarantees and indemnifications 33 1,609 522 78 498 2,707 973 Total guarantees $ 219 52,419 10,070 6,265 6,943 75,697 20,419 December 31, 2023 Standby letters of credit (1) $ 90 14,211 5,209 2,931 105 22,456 7,711 Direct pay letters of credit (1) 8 1,446 2,268 247 5 3,966 957 Loans and LHFS sold with recourse 72 249 2,957 3,385 7,228 13,819 10,612 Exchange and clearing house guarantees — 13,550 — — — 13,550 — Other guarantees and indemnifications 22 687 854 116 463 2,120 634 Total guarantees $ 192 30,143 11,288 6,679 7,801 55,911 19,914 (1) Standby and direct pay letters of credit are reported net of syndications and participations. 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 14.1 do not reflect economic hedges or collateral we could use to offset or recover losses we may incur under our guarantee agreements. Accordingly, these amounts are not an indication of expected loss. We believe the carrying value is more representative of our current 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. In determining the ACL for guarantees, we consider the credit risk of the related contingent obligation. For our guarantees in Table 14.1, non-investment grade represents those guarantees on which we have a higher risk of performance under the terms of the guarantee, which is determined based on an external rating or an internal credit grade that is below investment grade, if applicable. WRITTEN OPTIONS We enter into written foreign currency options and over-the-counter written equity put options that are derivative contracts that have the characteristics of a guarantee. The fair value of written options represents our view of the probability that we will be required to perform under the contract. The fair value of these written options was an asset of $385 million and $178 million at September 30, 2024, and December 31, 2023, respectively. The fair value may be an asset as a result of deferred premiums on certain option trades. The maximum exposure to loss represents the notional value of these derivative contracts. At September 30, 2024, the maximum exposure to loss was $33.3 billion, with $30.7 billion expiring in three years or less compared with $34.0 billion and $31.9 billion, respectively, at December 31, 2023. See Note 11 (Derivatives) for additional information regarding written derivative contracts. MERCHANT PROCESSING SERVICES We provide debit and credit card transaction processing services through 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 in connection with payment and delivery disputes between the merchant and the cardholder that are resolved in favor of the cardholder, referred to as a charge-back transaction. We estimate our potential maximum exposure to be the total merchant transaction volume processed in the preceding four months, which is generally the lifecycle for a charge-back transaction. As of September 30, 2024, our potential maximum exposure was approximately $597.4 billion, and related losses, including those from our joint venture entity, were insignificant. GUARANTEES OF SUBSIDIARIES 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 securities are not guaranteed by any other subsidiary of the Parent. The guaranteed liabilities were $1.3 billion and $834 million at September 30, 2024, and December 31, 2023, respectively. These guarantees rank on parity with all of the Parent’s other unsecured and unsubordinated indebtedness. OTHER COMMITMENTS As of September 30, 2024, and December 31, 2023, we had commitments to purchase equity securities of $6.7 billion and $9.2 billion, respectively, which predominantly included Federal Reserve Bank stock and tax credit investments accounted for using the equity method. 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 Table 14.1 in Other guarantees and indemnifications. We have commitments to enter into resale and securities borrowing agreements as well as repurchase and securities lending agreements with certain counterparties, including central clearing organizations. The amount of our unfunded contractual commitments for resale and securities borrowing agreements was $23.2 billion and $17.5 billion as of September 30, 2024, and December 31, 2023, respectively. The amount of our unfunded contractual commitments for repurchase and securities lending agreements was $253 million and $746 million as of September 30, 2024, and December 31, 2023, respectively. Given the nature of these commitments, they are excluded from Table 5.4 (Unfunded Credit Commitments) in Note 5 (Loans and Related Allowance for Credit Losses).

Securities and Other Collateral

Securities and Other Collateralized Financing Activities	9 Months Ended

Securities Financing Transactions [Abstract]
Securities and Other Collateralized Financing Activities	Note 15: Securities and Other Collateralized 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. We also enter into resale agreements involving collateral other than securities, such as loans, as part of our commercial lending business activities. OFFSETTING OF SECURITIES AND OTHER COLLATERALIZED FINANCING ACTIVITIES Table 15.1 presents resale and repurchase agreements subject to master repurchase agreements (MRA) and securities borrowing and lending agreements subject to master securities lending agreements (MSLA). Where legally enforceable, these master netting arrangements give the ability, in the event of default by the counterparty, to liquidate securities held as collateral and to offset receivables and payables with the same counterparty. Collateralized financings with the same counterparty are presented net on our consolidated balance sheet, provided certain criteria are met that permit balance sheet netting. The majority of 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 our consolidated balance sheet against the related liability. Collateral we received includes securities or loans and is not recognized on our consolidated 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. For additional information on collateral pledged and accepted, see Note 16 (Pledged Assets and Collateral). 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, the disclosure in this table is limited to 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 15.1, we also have balance sheet netting related to derivatives that is disclosed in Note 11 (Derivatives). Table 15.1: Offsetting – Securities and Other Collateralized Financing Activities (in millions) Sep 30, Dec 31, Assets: Resale and securities borrowing agreements Gross amounts recognized $ 160,792 129,282 Gross amounts offset in consolidated balance sheet (1) (36,322) (28,402) Net amounts in consolidated balance sheet (2) 124,470 100,880 Collateral received not recognized in consolidated balance sheet (3) (123,594) (99,970) Net amount (4) $ 876 910 Liabilities: Repurchase and securities lending agreements Gross amounts recognized $ 133,849 106,060 Gross amounts offset in consolidated balance sheet (1) (36,322) (28,402) Net amounts in consolidated balance sheet (5) 97,527 77,658 Collateral pledged but not netted in consolidated balance sheet (6) (97,431) (77,529) Net amount (4) $ 96 129 (1) Represents recognized amount of resale and repurchase agreements with counterparties subject to enforceable MRAs that have been offset within our consolidated balance sheet. (2) Includes $105.4 billion and $80.4 billion classified on our consolidated balance sheet in federal funds sold and securities purchased under resale agreements at September 30, 2024, and December 31, 2023, respectively. Also includes $19.1 billion and $20.5 billion classified on our consolidated balance sheet in loans at September 30, 2024, and December 31, 2023, 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. (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. 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 15.2 provides the gross amounts recognized on our consolidated balance sheet (before the effects of offsetting) of our liabilities for repurchase and securities lending agreements disaggregated by underlying collateral type. Table 15.2: Gross Obligations by Underlying Collateral Type (in millions) Sep 30, Dec 31, Repurchase agreements: Securities of U.S. Treasury and federal agencies $ 52,482 38,742 Securities of U.S. States and political subdivisions 502 579 Federal agency mortgage-backed securities 56,391 48,019 Non-agency mortgage-backed securities 2,113 1,889 Corporate debt securities 8,951 7,925 Asset-backed securities 2,288 2,176 Equity securities 2,201 635 Other 2,027 541 Total repurchases 126,955 100,506 Securities lending arrangements: Securities of U.S. Treasury and federal agencies 294 251 Federal agency mortgage-backed securities 2 31 Corporate debt securities 1,005 293 Equity securities 5,579 4,965 Other 14 14 Total securities lending 6,894 5,554 Total repurchases and securities lending $ 133,849 106,060 Table 15.3 provides the contractual maturities of our gross obligations under repurchase and securities lending agreements. Securities lending is executed under agreements that allow either party to terminate the transaction without notice, while repurchase agreements have a term structure that matures at a point in time. The overnight agreements require an election by both parties to roll the trade, while continuous agreements require an election by either party to terminate the agreement.

Financial Instruments Pledged as Collateral [Abstract]
Pledged Assets and Collateral	Note 16: Pledged Assets and Collateral Pledged Assets We pledge financial assets that we own to counterparties for the collateralization of securities and other collateralized financing activities, to secure trust and public deposits, and to collateralize derivative contracts. See Note 15 (Securities and Other Collateralized Financing Activities) for additional information on securities financing activities. As part of our liquidity management strategy, we may also pledge assets to secure borrowings and letters of credit from Federal Home Loan Banks (FHLBs), to maintain potential borrowing capacity with FHLBs and at the discount window of the Board of Governors of the Federal Reserve System (FRB), and for other purposes as required or permitted by law or insurance statutory requirements. The collateral that we pledge may include our own collateral as well as collateral that we have received from third parties and have the right to repledge. Table 16.1 provides the carrying values of assets recognized on our consolidated balance sheet that we have pledged to third parties. Assets pledged in transactions where our counterparty has the right to sell or repledge those assets are presented parenthetically on our consolidated balance sheet. VIE RELATED We also pledge assets in connection with various types of transactions entered into with VIEs, which are excluded from Table 16.1. These pledged assets can only be used to settle the liabilities of those entities. We also have loans recorded on our consolidated balance sheet which represent certain delinquent loans that are eligible for repurchase from GNMA loan securitizations. See Note 13 (Securitizations and Variable Interest Entities) for additional information on consolidated and unconsolidated VIE assets. Table 16.1: Pledged Assets (in millions) Sep 30, Dec 31, Pledged to counterparties that had the right to sell or repledge: Debt securities: Trading $ 83,197 62,537 Available-for-sale 1,491 5,055 Equity securities 10,272 2,683 All other assets 499 495 Total assets pledged to counterparties that had the right to sell or repledge 95,459 70,770 Pledged to counterparties that did not have the right to sell or repledge: Debt securities: Trading 6,025 2,757 Available-for-sale 96,993 64,511 Held-to-maturity 221,280 246,218 Loans 488,873 445,092 Equity securities 1,497 1,502 All other assets 1,523 1,195 Total assets pledged to counterparties that did not have the right to sell or repledge 816,191 761,275 Total pledged assets $ 911,650 832,045 Collateral Accepted We receive financial assets as collateral that we are permitted to sell or repledge. This collateral is obtained in connection with securities purchased under resale agreements and securities borrowing transactions, customer margin loans, and derivative contracts. We may use this collateral in connection with securities sold under repurchase agreements and securities lending transactions, derivative contracts, and short sales. At September 30, 2024, and December 31, 2023, the fair value of this collateral received that we have the right to sell or repledge was $255.0 billion and $216.6 billion, respectively, of which $123.7 billion and $103.3 billion, respectively, were sold or repledged.

Operating Segments

Segment Reporting [Abstract]
Operating Segments	Note 17: Operating Segments Our management reporting is organized into four reportable operating segments: Consumer Banking and Lending; Commercial Banking; Corporate and Investment Banking; and Wealth and Investment Management. All other business activities that are not included in the reportable operating segments have been included in Corporate. We define our reportable operating segments by type of product and customer segment, and their results are based on our management reporting process. The management reporting process measures the performance of the reportable operating segments based on the Company’s management structure, and the results are regularly reviewed with our Chief Executive Officer and relevant senior management. The management reporting process is based on U.S. GAAP and includes specific adjustments, such as funds transfer pricing for asset/liability management, shared revenue and expenses, and taxable-equivalent adjustments to consistently reflect income from taxable and tax-exempt sources, which allows management to assess performance consistently across the operating segments. Consumer Banking and Lending offers diversified financial products and services for consumers and small businesses with annual sales generally up to $10 million. These financial products and services include checking and savings accounts, credit and debit cards as well as home, auto, personal, and small business lending. Commercial Banking provides financial solutions to private, family owned and certain public companies. Products and services include banking and credit products across multiple industry sectors and municipalities, secured lending and lease products, and treasury management. Corporate and Investment Banking delivers a suite of capital markets, banking, and financial products and services to corporate, commercial real estate, government and institutional clients globally. Products and services include corporate banking, investment banking, treasury management, commercial real estate lending and servicing, equity and fixed income solutions as well as sales, trading, and research capabilities. Wealth and Investment Management provides personalized wealth management, brokerage, financial planning, lending, private banking, trust and fiduciary products and services to affluent, high-net worth and ultra-high-net worth clients. We operate through financial advisors in our brokerage and wealth offices, consumer bank branches, independent offices, and digitally through WellsTrade ® and Intuitive Investor ®. Corporate includes corporate treasury and enterprise functions, net of allocations (including funds transfer pricing, capital, liquidity and certain expenses), in support of the reportable operating segments, as well as our investment portfolio and venture capital and private equity investments. Corporate also includes certain lines of business that management has determined are no longer consistent with the long-term strategic goals of the Company as well as results for previously divested businesses. Basis of Presentation FUNDS TRANSFER PRICING Corporate treasury manages a funds transfer pricing methodology that considers interest rate risk, liquidity risk, and other product characteristics. Operating segments pay a funding charge for their assets and receive a funding credit for their deposits, both of which are included in net interest income. The net impact of the funding charges or credits is recognized in corporate treasury. REVENUE AND EXPENSE SHARING When lines of business jointly serve customers, the line of business that is responsible for providing the product or service recognizes revenue or expense with a referral fee paid or an allocation of cost to the other line of business based on established internal revenue-sharing agreements. When a line of business uses a service provided by another line of business or enterprise function (included in Corporate), expense is generally allocated based on the cost and use of the service provided. We periodically assess and update our revenue and expense allocation methodologies. TAXABLE-EQUIVALENT ADJUSTMENTS Taxable-equivalent adjustments related to tax-exempt income on certain loans and debt securities are included in net interest income, while taxable-equivalent adjustments related to income tax credits for affordable housing and renewable energy investments are included in noninterest income, in each case with corresponding impacts to income tax expense (benefit). Adjustments are included in Corporate, Commercial Banking, and Corporate and Investment Banking and are eliminated to reconcile to the Company’s consolidated financial results.

(2) These revenue types are related to financial assets and liabilities, including loans, leases, securities and derivatives, with additional details included in other footnotes to our financial statements. (3) We earned trailing commissions of $238 million and $701 million for the third quarter and first nine months of 2024, respectively, and $230 million and $684 million for the third quarter and first nine months of 2023, respectively. (4) The cost of credit card rewards and rebates of $694 million and $2.0 billion for the third quarter and first nine months of 2024, respectively, and $652 million and $1.9 billion for the third quarter and first nine months of 2023, respectively, are presented net against the related revenue. Expenses OPERATING LOSSES Operating losses consist of expenses related to: • Legal actions such as litigation and regulatory matters. For additional information on legal actions, see Note 10 (Legal Actions); • Customer remediation activities, which are associated with our efforts to identify areas or instances where customers may have experienced financial harm and provide remediation as appropriate. We have accrued for the probable and estimable costs related to our customer remediation activities, which amounts may change based on additional facts and information, as well as ongoing reviews and communications with our regulators; and • Other business activities such as deposit overdraft losses, fraud losses, and isolated instances of customer redress. Table 18.2 provides the components of our operating losses included in our consolidated statement of income. Table 18.2: Operating Losses Quarter ended September 30, Nine months ended September 30, (in millions) 2024 2023 2024 2023 Legal actions $ 76 175 $ 228 115 Customer remediation 22 (30) 634 133 Other 195 184 557 580 Total operating losses $ 293 329 $ 1,419 828 Operating losses may have significant variability given the inherent and unpredictable nature of legal actions and customer remediation activities. The timing and determination of the amount of any associated losses for these matters depends on a variety of factors, some of which are outside of our control. OTHER EXPENSES Regulatory Charges and Assessments expense, which is included in other noninterest expense, was $212 million and $1.1 billion in the third quarter and first nine months of 2024, respectively, compared with $277 million and $849 million in the same periods a year ago, and predominantly consisted of Federal Deposit Insurance Corporation (FDIC) deposit assessment expense. In November 2023, the FDIC finalized a rule to recover losses to the FDIC deposit insurance fund as a result of bank failures in the first half of 2023. Under the rule, the FDIC will collect a special assessment based on an insured depository institution’s estimated amount of uninsured deposits. Upon the FDIC’s finalization of the rule, we expensed an estimated amount of our special assessment of $1.9 billion (pre-tax) in fourth quarter 2023. During 2024, the FDIC provided updates on losses to the deposit insurance fund, which resulted in a reversal of expense of $63 million (pre-tax) in the third quarter of 2024 and an additional expense of $273 million (pre-tax) in the first nine months of 2024 for the estimated amount of the special assessment. We expect the ultimate amount of the special assessment may continue to change as the FDIC determines the actual net losses to the deposit insurance fund.

The FRB establishes capital requirements for the consolidated financial holding company, and the Office of the Comptroller of the Currency (OCC) has similar requirements for the Company’s national banks, including Wells Fargo Bank, N.A. (the Bank). Table 22.1 presents regulatory capital information for the Company and the Bank in accordance with Basel III capital requirements. We must calculate our risk-based capital ratios under both the Standardized and Advanced Approaches. 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.

(1) The supplementary leverage ratio consists of Tier 1 capital divided by total leverage exposure. Total leverage exposure consists of adjusted average assets plus certain off-balance sheet exposures. Adjusted average assets consists of total quarterly average assets less goodwill and other permitted Tier 1 capital deductions (net of deferred tax liabilities). (2) The Tier 1 leverage ratio consists of Tier 1 capital divided by total quarterly average assets, excluding goodwill and certain other items as determined under the rule. At September 30, 2024, the Common Equity Tier 1 (CET1), Tier 1 and Total capital ratio requirements for the Company included a global systemically important bank (G-SIB) surcharge of 1.50% and a countercyclical buffer of 0.00%. In addition, these ratios included a stress capital buffer of 2.90% under the Standardized Approach and a capital conservation buffer of 2.50% under the Advanced Approach. The Company is required to maintain these risk-based capital ratios and to maintain a supplementary leverage ratio (SLR) that included a supplementary leverage buffer of 2.00% to avoid restrictions on capital distributions and discretionary bonus payments. The CET1, Tier 1 and Total capital ratio requirements for the Bank included a capital conservation buffer of 2.50% under both the Standardized and Advanced Approaches. The G-SIB surcharge and countercyclical buffer are not applicable to the Bank. At September 30, 2024, the Bank and our other insured depository institutions were considered well-capitalized under the requirements of the Federal Deposit Insurance Act. Capital Planning Requirements The FRB’s capital plan rule establishes capital planning and other requirements that govern capital distributions, including dividends and share repurchases, by certain large bank holding companies (BHCs), including Wells Fargo. The FRB conducts an annual Comprehensive Capital Analysis and Review exercise and 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 the requirements of the capital plan rule and is also subject to the Parent meeting or exceeding certain regulatory capital minimums. Loan and Dividend Restrictions Federal law restricts the amount and the terms of both credit and non-credit transactions between a bank and its nonbank affiliates. Additionally, federal laws and regulations limit, and regulators can impose additional limitations on, the dividends that a national bank may pay. 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. In addition, we have entered into a Support Agreement dated June 28, 2017, as amended and restated on June 26, 2019, among Wells Fargo & Company, the parent holding company (Parent), WFC Holdings, LLC, an intermediate holding company and subsidiary of the Parent (IHC), the Bank, Wells Fargo Securities, LLC, Wells Fargo Clearing Services, LLC, and certain other subsidiaries of the Parent designated from time to time as material entities for resolution planning purposes or identified from time to time as related support entities in our resolution plan, pursuant to which 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. For additional information on loan and dividend restrictions, see Note 26 (Regulatory Capital Requirements and Other Restrictions) in our 2023 Form 10-K. Cash Restrictions Cash and cash equivalents may be restricted as to usage or withdrawal. Table 22.2 provides a summary of restrictions on cash and cash equivalents .

Significant Accounting Policies [Line Items]
Business Description and Basis of Presentation	Wells Fargo & Company is a diversified financial services company. We provide banking, investment and mortgage products and services, as well as consumer and commercial finance, through banking locations and offices, the internet and other distribution channels to individuals, businesses and institutions in all 50 states, the District of Columbia, and in countries outside the U.S. 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 a 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, 2023 (2023 Form 10-K). There were no material changes to these policies in the first nine months of 2024.
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 5 (Loans and Related Allowance for Credit Losses) and Note 3 (Available-for-Sale and Held-to-Maturity Debt Securities)); • valuations of residential mortgage servicing rights (MSRs) (Note 6 (Mortgage Banking Activities) and Note 13 (Securitizations and Variable Interest Entities)); • valuations of financial instruments (Note 12 (Fair Values of Assets and Liabilities)); • liability for legal actions (Note 10 (Legal Actions)); • income taxes; and • goodwill impairment (Note 7 (Intangible Assets and Other Assets)). 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 2023 Form 10-K.
Accounting Standards Adopted in 2024	Accounting Standards Adopted in 2024 In 2024, we adopted the following new accounting guidance: • Accounting Standards Update (ASU) 2023-02, Investments – Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method • ASU 2022-03, Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions
Subsequent Events	Subsequent Events We have evaluated the effects of events that have occurred subsequent to September 30, 2024, and there have been no material events that would require recognition in our third quarter 2024 consolidated financial statements or disclosure in the Notes to the consolidated financial statements.
Accounting Standards Update 2023-02 [Member]
Significant Accounting Policies [Line Items]
Accounting Standards Adopted in 2024	ASU 2023-02 expands the use of the proportional amortization method of accounting for tax credit investments, which previously was limited to affordable housing investments that generate low-income housing tax credits. Upon adoption of the Update, an entity may elect to account for equity investments that generate income tax credits and benefits using the proportional amortization method if certain eligibility criteria are met. The proportional amortization method amortizes the cost of a tax credit investment in proportion to the income tax credits and income tax benefits received. The amortization and related income tax credits and benefits are recorded on a net basis within income tax expense. The cost of an investment includes unfunded commitments that are either legally binding or contingent but probable of funding. Such unfunded commitments are not recognized under other methods of accounting. We adopted the Update on January 1, 2024, on a modified retrospective basis with a cumulative effect adjustment to retained earnings. Upon adoption, we elected to account for eligible investments in our renewable energy tax credit portfolio using the proportional amortization method. These investments were previously accounted for using the equity method. We also elected to continue use of the proportional amortization method to account for our affordable housing investments. In addition, we elected to classify liabilities recognized for unfunded commitments related to proportional amortization method investments in accrued expenses and other liabilities on our consolidated balance sheet, including a change to unfunded commitments for affordable housing investments that were previously included in long-term debt. Prior period amounts were not impacted by these accounting changes. Table 1.1 presents the transition adjustments recorded upon the adoption of ASU 2023-02 as of January 1, 2024.

Accounting Standards Update 2022-03 [Member]
Significant Accounting Policies [Line Items]
Accounting Standards Adopted in 2024	ASU 2022-03 clarifies the guidance regarding the measurement of fair value of equity securities subject to contractual restrictions that prohibit the sale of the security. Specifically, that such restrictions are not part of the unit of account of the security and therefore are not considered when measuring fair value. We adopted the Update on January 1, 2024, on a prospective basis. The Update did not have a material impact to our consolidated financial statements.

The net unrealized gains (losses) for AFS debt securities are reported as a component of accumulated other comprehensive income (AOCI), net of the ACL and applicable income taxes. Information on debt securities held for trading is included in Note 2 (Trading Activities). Outstanding balances exclude accrued interest receivable on AFS and HTM debt securities, which are included in other assets. See Note 7 (Intangible Assets and Other Assets) for additional information on accrued interest receivable. Amounts considered to be uncollectible are reversed through interest income. The interest income reversed in the third quarter and first nine months of both 2024 and 2023 was insignificant.

Loans Outstanding	Table 5.1 presents total loans outstanding by portfolio segment and class of financing receivable. Loans are reported at their outstanding principal balances net of any unearned income, cumulative charge-offs, unamortized deferred fees and costs on originated loans, and unamortized premiums or discounts on purchased loans. These amounts were less than 1% of our total loans outstanding at both September 30, 2024, and December 31, 2023. Outstanding balances exclude accrued interest receivable on loans, except for certain revolving loans, such as credit card loans. See Note 7 (Intangible Assets and Other Assets) for additional information on accrued interest receivable. Amounts considered to be uncollectible are reversed through interest income. During the first nine months of 2024, we reversed accrued interest receivable of $33 million for our commercial portfolio segment and $300 million for our consumer portfolio segment, compared with $31 million and $188 million, respectively, for the same period a year ago.

Commercial Loan Categories by Risk Categories and Vintage	Table 5.7 provides the outstanding balances of our commercial loan portfolio by risk category and credit quality information by origination year 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 for a borrower experiencing financial difficulty.

Prepayment speeds are influenced by mortgage interest rates as well as our estimation of drivers of borrower behavior.
Managed Servicing Portfolio	We present information for our managed servicing portfolio in Table 6.3 using unpaid principal balance for loans serviced and subserviced for others and carrying 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. The credit risk related to these advances is limited since the reimbursement is generally senior to cash payments to investors and are generally reimbursed within a short timeframe from cash flows from the trust, government- sponsored enterprise (GSEs), insurer, or 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. We also advance payments of taxes and insurance for our owned loans which are collectible from the borrower. Servicing advances on owned loans are written-off when deemed uncollectible.

Valuation Techniques – Recurring Basis	Table 12.3 provides quantitative information about the valuation techniques and significant unobservable inputs used in the valuation of our Level 3 assets and liabilities measured at fair value on a recurring basis. The significant unobservable inputs for Level 3 assets 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 (for additional information on vendor-developed valuations, see Note 15 (Fair Values of Assets and Liabilities) in our 2023 Form 10-K). 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.

Fair Value Estimates for Financial Instruments	Table 12.9 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 the scope of this table, such as certain insurance contracts, certain nonmarketable equity securities, 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 12.9. 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 $505 million and $575 million at September 30, 2024, and December 31, 2023, respectively. The total of the fair value calculations presented does not represent, and should not be construed to represent, the underlying fair value of the Company.

Securitizations and Variable Interest Entities [Abstract]
Transfers with Continuing Involvement	Table 13.1 presents information about transfers of assets during the periods presented for which we recorded the transfers as sales and have continuing involvement with the transferred assets. In connection with these transfers, we received proceeds and recorded servicing assets and securities. Each of these interests are initially measured at fair value. Servicing rights are classified as Level 3 measurements, and generally securities are classified as Level 2. Transfers of residential mortgage loans are transactions with the GSEs or GNMA and generally result in no gain or loss because the loans are typically measured at fair value on a recurring basis. Transfers of commercial mortgage loans include both transactions with the GSEs or GNMA and nonconforming transactions. These commercial mortgage loans are carried at the lower of cost or market, and we recognize gains on such transfers when the market value is greater than the carrying value of the loan when it is sold.

(2) Represents assets or liabilities recognized at securitization settlement date related to our continuing involvement in the transferred assets. (3) Represents debt securities obtained at securitization settlement held for investment purposes that are classified as available-for-sale or held-to-maturity. Excludes trading debt securities held temporarily for market-marking purposes, which are sold to third parties at or shortly after securitization settlement, of $1.1 billion and $2.8 billion during the third quarter and first nine months of 2024, respectively, and $1.3 billion and $5.0 billion during the third quarter and first nine months of 2023, respectively.
Residential MSRs – Assumptions at Securitization Date	Table 13.2 presents the key weighted-average assumptions we used to initially measure residential MSRs recognized during the periods presented. Table 13.2: Residential MSRs – Assumptions at Securitization Date 2024 2023 Quarter ended September 30, Prepayment rate (1) 19.9 % 16.0 Discount rate 9.9 9.9 Cost to service ($ per loan) $ 69 131 Nine months ended September 30, Prepayment rate (1) 18.1 % 17.2 Discount rate 10.1 9.7 Cost to service ($ per loan) $ 180 171 (1) Includes a blend of prepayment speeds and expected defaults. Prepayment speeds are influenced by mortgage interest rates as well as our estimation of drivers of borrower behavior.
Sold or Securitized Loans Serviced for Others	Table 13.3 presents information about loans that we have originated and sold or securitized in which we have ongoing involvement as servicer. For loans sold or securitized where servicing is our only form of continuing involvement, we generally experience a loss only 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. Table 13.3 excludes mortgage loans sold to and held or securitized by GSEs or GNMA of $538.1 billion and $592.5 billion at September 30, 2024, and December 31, 2023, respectively. Delinquent loans include loans 90 days or more past due and loans in bankruptcy, regardless of delinquency status.

Unconsolidated VIEs	Table 13.4 provides a summary of our exposure to the unconsolidated VIEs described above, which includes investments in securities, loans, guarantees, liquidity agreements, commitments and certain derivatives. We exclude certain transactions with unconsolidated VIEs when our continuing involvement is temporary or administrative in nature or insignificant in size. In Table 13.4, “Total VIE assets” represents the remaining principal balance of assets held by unconsolidated VIEs using the most current information available. “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. Debt, guarantees and other commitments include amounts related to lending arrangements, liquidity agreements, and certain loss sharing obligations associated with loans originated, sold, and serviced under certain GSE programs. “Maximum exposure to loss” 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.

Transactions with Consolidated VIEs	Table 13.6 presents a summary of financial assets and liabilities of our consolidated VIEs. The carrying value represents assets and liabilities recognized on our consolidated balance sheet. “Total VIE assets” includes affiliate balances that are eliminated upon consolidation, and therefore in some instances will differ from the carrying value of assets. On our consolidated balance sheet, we separately disclose (1) the consolidated assets of certain VIEs that can only be used to settle the liabilities of those VIEs, and (2) the consolidated liabilities of certain VIEs for which the VIE creditors do not have recourse to Wells Fargo.

Securities Financing Transactions [Abstract]
Offsetting – Securities and Other Collateralized Financing Activities	Table 15.1 presents resale and repurchase agreements subject to master repurchase agreements (MRA) and securities borrowing and lending agreements subject to master securities lending agreements (MSLA). Where legally enforceable, these master netting arrangements give the ability, in the event of default by the counterparty, to liquidate securities held as collateral and to offset receivables and payables with the same counterparty. Collateralized financings with the same counterparty are presented net on our consolidated balance sheet, provided certain criteria are met that permit balance sheet netting. The majority of 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 our consolidated balance sheet against the related liability. Collateral we received includes securities or loans and is not recognized on our consolidated 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. For additional information on collateral pledged and accepted, see Note 16 (Pledged Assets and Collateral). 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, the disclosure in this table is limited to 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 15.1, we also have balance sheet netting related to derivatives that is disclosed in Note 11 (Derivatives).

(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.

Regulatory Capital Requirements and Other Restrictions [Abstract]
Regulatory Capital Information	Table 22.1 presents regulatory capital information for the Company and the Bank in accordance with Basel III capital requirements. We must calculate our risk-based capital ratios under both the Standardized and Advanced Approaches. 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.
