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. 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)); • valuations of residential mortgage servicing rights (MSRs) (Note 6 (Mortgage Banking Activities) and Note 16 (Securitizations and Variable Interest Entities)); • valuations of financial instruments (Note 15 (Fair Values of Assets and Liabilities)); • liabilities for contingent litigation losses (Note 13 (Legal Actions)); • income taxes (Note 22 (Income Taxes)); and • goodwill impairment (Note 7 (Intangible Assets and Other Assets)). Actual results could differ from those estimates. Accounting Standards Adopted in 2022 In 2022, we adopted the following new accounting guidance: • Accounting Standards Update (ASU or Update) 2020-06 – Debt – Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging – Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity • ASU 2021-05 – Leases (Topic 842): Lessors – Certain Leases with Variable Lease Payments • ASU 2021-10 – Government Assistance (Topic 832): Disclosures by Business Entities about Government Assistance • ASU 2022-06 – Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848 ASU 2020-06 simplifies the accounting for convertible financial instruments that embody characteristics of debt and equity by (1) eliminating accounting models for convertible financial instruments with cash conversion and beneficial conversion features within Accounting Standards Codification (ASC) Subtopic 470-20, (2) removing three equity classification requirements for a contract in an entity’s own equity to qualify for the derivative scope exception in ASC Subtopic 815-40, and (3) prescribing the method used for computing earnings per share. We adopted this Update prospectively in first quarter 2022. This Update did not have a material impact to our consolidated financial statements. ASU 2021-05 amends ASC Topic 842 – Leases and provides specific guidance for lessors whose leases include variable lease payments that are not dependent on a reference index or rate and otherwise would have resulted in the recognition of a loss at lease commencement (a day 1 loss). Prior to ASU 2016-02, variable lease payments were excluded from the definition of lease payments for lessors measuring their net investment loss in a sales-type lease or direct financing lease. This often resulted in a day 1 loss, even if the lessor expected the arrangement to be profitable overall. We adopted this Update prospectively in first quarter 2022. This Update did not have a material impact to our consolidated financial statements. ASU 2021-10 created a new topic in the codification, ASC Topic 832. The ASU requires annual disclosures for a business entity that has received government assistance and uses a grant or contribution accounting model by analogy to other accounting guidance. We adopted this Update in fourth quarter 2022 on a prospective basis. This Update did not have a material impact to our consolidated financial statements. ASU 2022-06 defers the sunset date of ASC Topic 848 – Reference Rate Reform from December 31, 2022, to December 31, 2024, to extend the ability to apply the guidance in Topic 848, which provides temporary optional guidance to ease the burden in accounting for reference rate reform on financial reporting. We adopted this Update prospectively in fourth quarter 2022. This Update did not have a material impact to our consolidated financial statements. Consolidation Our consolidated financial statements include the accounts of the Parent and our subsidiaries in which we have a controlling financial interest. When our consolidated subsidiaries follow specialized industry accounting, that accounting is retained in consolidation. We are also a variable interest holder in certain entities in which equity investors do not have the characteristics of a controlling financial interest or where the entity does not have enough equity at risk to finance its activities without additional subordinated financial support from other parties (collectively referred to as variable interest entities (VIEs)). Our variable interest arises from contractual, ownership or other monetary interests in the entity, which change with fluctuations in the fair value of the entity’s net assets. We consolidate a VIE if we are the primary beneficiary, which is when we have both the power to direct the activities that most significantly impact the VIE and a variable interest that could potentially be significant to the VIE. To determine whether or not a variable interest we hold could potentially be significant to the VIE, we consider both qualitative and quantitative factors regarding the nature, size and form of our involvement with the VIE. We assess whether or not we are the primary beneficiary of a VIE on an ongoing basis. Significant intercompany accounts and transactions are eliminated in consolidation. When we have significant influence over operating and financing decisions for a company but do not own a majority of the voting equity interests, we account for the investment using the equity method of accounting, which requires us to recognize our proportionate share of the company’s earnings. If we do not have significant influence, we account for the equity security under the fair value method, cost meth od or measurement alternative. Noncontrolling interests represent the portion of net income and equity attributable to third-party owners of consolidated subsidiaries that are not wholly-owned by Wells Fargo. Substantially all of our noncontrolling interests relate to our affiliated venture capital and private equity businesses. Cash, Cash Equivalents, and Restricted Cash Cash, cash equivalents and restricted cash are recorded at amortized cost and include cash on hand, cash items in transit, and amounts due from or held with other depository institutions. See Note 25 (Regulatory Capital Requirements and Other Restrictions) for additional information on the restrictions on cash and cash equivalents. Trading Activities We engage in trading activities to accommodate the investment and risk management activities of our customers. These activities predominantly occur in our Corporate and Investment Banking reportable operating segment. Trading assets and liabilities include debt securities, equity securities, loans held for sale, derivatives and short sales, which are reported within our consolidated balance sheet based on the accounting classification of the instrument. In addition, debt securities that are held for investment purposes that we have elected to account for under the fair value method, are classified as trading. Our trading assets and liabilities are carried on our consolidated balance sheet at fair value with changes in fair value recognized in net gains from trading and securities within noninterest income. Interest income and interest expense are recognized in net interest income. Customer accommodation trading activities include our actions as an intermediary to buy and sell financial instruments and market-making activities. We also take positions to manage our exposure to customer accommodation activities. We hold financial instruments for trading in long positions, as well as short positions, to facilitate our trading activities. As an intermediary, we interact with market buyers and sellers to facilitate the purchase and sale of financial instruments to meet the anticipated or current needs of our customers. For example, we may purchase or sell a derivative to a customer who wants to manage interest rate risk exposure. We typically enter into an offsetting derivative or security position to manage our exposure to the customer transaction. We earn income based on the transaction price difference between the customer transaction and the offsetting position, which is reflected in earnings where the fair value changes and related interest income and expense of the positions are recorded. Our market-making activities include taking long and short trading positions to facilitate customer order flow. These activities are typically executed on a short-term basis. As a market-maker we earn income due to: (1) the difference between the price paid or received for the purchase and sale of the security (bid-ask spread), (2) the net interest income of the positions, and (3) the changes in fair value of the trading positions held on our consolidated balance sheet. Additionally, we may enter into separate derivative or security positions to manage our exposure related to our long and short trading positions taken in our market-making activities. Income earned on these market-making activities are reflected in earnings where the fair value changes and related interest income and expense of the positions are recorded. Available-for-Sale and Held-to-Maturity Debt Securities Our investments in debt securities that are not held for trading purposes are classified as either available-for-sale (AFS) or held-to-maturity (HTM). Investments in debt securities for which the Company does not have the positive intent and ability to hold to maturity are classified as AFS. AFS debt securities are measured at fair value, with unrealized gains and losses reported in accumulated other comprehensive income (AOCI). The amount reported in other comprehensive income (OCI) is net of the allowance for credit losses (ACL) and applicable income taxes. Investments in debt securities for which the Company has the positive intent and ability to hold to maturity are classified as HTM. HTM debt securities are measured at amortized cost, net of ACL. See Note 3 (Available-for-Sale and Held-to-Maturity Debt Securities) for additional information. INTEREST INCOME AND GAIN/LOSS RECOGNITION Unamortized premiums and discounts are recognized in interest income over the contractual life of the security using the effective interest method, except for purchased callable debt securities carried at a premium. For purchased callable debt securities carried at a premium, the premium is amortized into interest income to the next call date using the effective interest method. As principal repayments are received on securities (e.g., mortgage-backed securities (MBS)), a proportionate amount of the related premium or discount is recognized in income so that the effective interest rate on the remaining portion of the security continues unchanged. We recognize realized gains and losses on the sale of debt securities in net gains from trading and securities within noninterest income using the specific identification method. IMPAIRMENT AND CREDIT LOSSES Unrealized losses on AFS debt securities are driven by a number of factors, including changes in interest rates and credit spreads which impact most types of debt securities, and prepayment rates which impact MBS and collateralized loan obligations (CLO). Additional considerations for certain types of AFS debt securities include: • Debt securities of U.S. Treasury and federal agencies, including federal agency MBS, are not impacted by credit movements given the explicit or implicit guarantees provided by the U.S. government. • Debt securities of U.S. states and political subdivisions are most impacted by changes in the relationship between municipal and term funding credit curves rather than by changes in the credit quality of the underlying securities. • Structured securities, such as MBS and CLO, are also impacted by changes in projected collateral losses of assets underlying the security. For AFS debt securities where fair value is less than amortized cost basis, we recognize impairment in earnings if we have the intent to sell the security or if it is more likely than not that we will be required to sell the security before recovery of its amortized cost basis. Impairment is recognized in net gains on trading and securities within noninterest income equal to the difference between the amortized cost basis, net of ACL, and the fair value of the AFS debt security. Following the recognition of this impairment, the AFS debt security’s new amortized cost basis is fair value. For AFS debt securities where fair value is less than amortized cost basis where we did not recognize impairment in earnings, we record an ACL as of the balance sheet date to the extent unrealized loss is due to credit losses. See the “Allowance for Credit Losses” section in this Note for our accounting policies relating to the ACL for debt securities, which also includes debt securities classified as HTM. TRANSFERS BETWEEN CATEGORIES OF DEBT SECURITIES Transfers of debt securities from the AFS to HTM classification are recorded at fair value, and accordingly the amortized cost of the security transferred to HTM is adjusted to fair value. Unrealized gains or losses reported in AOCI at the transfer date are amortized into earnings over the same period as the unamortized premiums and discounts using the effective interest method. Any ACL previously recorded under the AFS debt security model is reversed and an ACL under the HTM debt security model is re-established. The reversal and re-establishment of the ACL are recorded in provision for credit losses. Transfers of debt securities from the HTM to AFS classification are recorded at fair value. The HTM amortized cost (excluding any ACL previously recorded under the HTM debt security model) becomes the AFS amortized cost, and the debt security is remeasured at fair value with the unrealized gains and losses reported in OCI. Any ACL previously recorded under the HTM debt security model is reversed and an ACL under the AFS debt security model is re-established. The reversal and re-establishment of the ACL are recorded in provision expense. Transfers from HTM to AFS are only expected to occur under limited circumstances. NONACCRUAL AND PAST DUE, AND CHARGE-OFF POLICIES We generally place debt securities on nonaccrual status using factors similar to those described for loans. When we place a debt security on nonaccrual status, we reverse the accrued unpaid interest receivable against interest income and suspend the amortization of premiums and accretion of discounts. If the ultimate collectability of the principal is in doubt on a nonaccrual debt security, any cash collected is first applied to reduce the security’s amortized cost basis to zero, followed by recovery of amounts previously charged off, and subsequently to interest income. Generally, we return a debt security to accrual status when all delinquent interest and principal become current under the contractual terms of the security and collectability of remaining principal and interest is no longer doubtful. Our debt securities are considered past due when contractually required principal or interest payments have not been made on the due dates. Our charge-off policy for debt securities are similar to those described for loans. Subsequent to charge-off, the debt security will be designated as nonaccrual and follow the process described above for any cash received. Securities and Other Collateralized Financing Agreements Resale and repurchase agreements, as well as securities borrowing and lending agreements, are accounted for as collateralized financing transactions and are recorded at the acquisition or sale price plus accrued interest. We monitor the fair value of securities or other assets purchased and sold as well as the collateral pledged and received. Additional collateral is pledged or returned to maintain the appropriate collateral position for the transactions. These financing transactions do not create material credit risk given the collateral provided and the related monitoring process. We include securities purchased under securities financing agreements in federal funds sold and securities purchased under resale agreements on our consolidated balance sheet. We include collateral other than securities purchased under resale agreements in Loans on our consolidated balance sheet. We include securities sold under securities financing agreements in short-term borrowings on our consolidated balance sheet. At December 31, 2022 and 2021, short-term borrowings were primarily comprised of federal funds purchased and securities sold under agreements to repurchase. Assets and liabilities arising from securities and other collateralized financing transactions with a single counterparty are presented net on the balance sheet provided they meet certain criteria that permit balance sheet netting. See Note 18 (Pledged Assets and Collateral) for additional information on our offsetting policy. Loans Held for Sale Loans held for sale (LHFS) generally includes commercial and residential mortgage loans originated or purchased for sale in the securitization or whole loan market. We have elected the fair value option for a majority of residential LHFS (see Note 15 (Fair Values of Assets and Liabilities)). The remaining residential LHFS are held at the lower of cost or fair value (LOCOM) and are measured on a pool level basis. Commercial LHFS are generally held at LOCOM and are measured on an individual loan basis. We have elected the fair value option for certain commercial loans included in LHFS that are used in market-making activities for our trading business. Gains and losses on residential and commercial mortgage LHFS are generally recorded in mortgage banking noninterest income. Gains and losses on trading LHFS are recognized in net gains from trading activities. Gains and losses on other LHFS are recognized in other noninterest income. Direct loan origination costs and fees for LHFS under the fair value option are recognized in earnings at origination. For LHFS recorded at LOCOM, direct loan origination costs and fees are deferred at origination and are recognized in earnings at time of sale. Interest income on LHFS is calculated based upon the note rate of the loan and is recorded in interest income. Commitments to originate mortgage LHFS are accounted for as derivatives and are measured at fair value. When a determination is made at the time of commitment to originate loans as held for investment, it is our intent to hold these loans to maturity or for the foreseeable future, subject to periodic review under our management evaluation processes, including corporate asset/liability management. If subsequent changes occur, including changes in interest rates, our business strategy, or other market conditions, we may change our intent to hold these loans. When management makes this determination, we immediately transfer these loans to the LHFS portfolio at LOCOM. Loans 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. Unearned income, deferred fees and costs, and discounts and premiums are amortized to interest income generally over the contractual life of the loan using the effective interest method. Loan commitment fees collected at closing are deferred and amortized to noninterest income on a straight-line basis over the commitment period if loan funding is unlikely. Upon funding, deferred loan commitment fees are amortized to interest income over the contractual life of the loan. Loans also include financing leases where we are the lessor (see the “Leasing Activity” section in this Note for our accounting policy for leases) and resale agreements involving collateral other than securities (see “Securities and Other Collateralized Financing Agreements” section in this Note for our accounting policy for other collateralized financing agreements). See Note 5 (Loans and Related Allowance for Credit Losses) for additional information regarding our accounting for loans. NONACCRUAL AND PAST DUE LOANS We generally place loans on nonaccrual status when: • the full and timely collection of interest or principal becomes uncertain (generally based on an assessment of the borrower’s financial condition and the adequacy of collateral, if any), such as in bankruptcy or other circumstances; • they are 90 days (120 days with respect to residential mortgage loans) past due for interest or principal, unless the loan is both well-secured and in the process of collection; • part of the principal balance has been charged off; or • for junior lien mortgage loans, we have evidence that the related first lien mortgage may be 120 days past due or in the process of foreclosure regardless of the junior lien delinquency status. Credit card loans are not placed on nonaccrual status, but are generally fully charged off when the loan reaches 180 days past due. When we place a loan on nonaccrual status, we reverse the accrued unpaid interest receivable against interest income and suspend amortization of any net deferred fees. If the ultimate collectability of the recorded loan balance is in doubt on a nonaccrual loan, the cost recovery method is used and cash collected is applied to first reduce the carrying value of the loan to zero and then as a recovery of prior charge-offs. Otherwise, interest income may be recognized to the extent cash is received. Generally, we return a loan to accrual status when all delinquent interest and principal become current under the terms of the loan agreement and collectability of remaining principal and interest is no longer doubtful. We may re-underwrite modified loans at the time of a restructuring to determine if there is sufficient evidence of sustained repayment capacity based on the borrower’s financial strength, including documented income, debt to income ratios and other factors. If the borrower has demonstrated performance under the previous terms and the underwriting process shows the capacity to continue to perform under the restructured terms, the loan will generally remain in accruing status. When a loan classified as a troubled debt restructuring (TDR) performs in accordance with its modified terms, the loan either continues to accrue interest (for performing loans) or will return to accrual status after the borrower demonstrates a sustained period of performance (generally six consecutive months of payments, or equivalent, inclusive of consecutive payments made prior to the modification). Loans will be placed on nonaccrual status and a corresponding charge-off is recorded if the re-underwriting did not include an evaluation of the borrower’s ability to repay or we believe it is probable that principal and interest contractually due under the modified terms of the agreement will not be collectible. Our loans are considered past due when contractually required principal or interest payments have not been made on the due dates. LOAN CHARGE-OFF POLICIES For commercial loans, we generally fully charge off or charge down to net realizable value (fair value of collateral, less estimated costs to sell) for loans secured by collateral when: • management judges the loan to be uncollectible; • repayment is deemed to be protracted beyond reasonable time frames; • the loan has been classified as a loss by either our internal loan review process or our banking regulatory agencies; • the customer has filed bankruptcy and the loss becomes evident owing to a lack of assets; • the loan is 180 days past due unless both well-secured and in the process of collection; or • the loan is probable of foreclosure, and we have received an appraisal of less than the recorded loan balance. For consumer loans, we fully charge off or charge down to net realizable value when deemed uncollectible due to bankruptcy or other factors, or no later than reaching a defined number of days past due, as follows: • Residential mortgage loans – We generally charge down to net realizable value when the loan is 180 days past due and fully charge-off when the loan exceeds extended delinquency dates. • Auto loans – We generally fully charge off when the loan is 120 days past due. • Credit card loans – We generally fully charge off when the loan is 180 days past due. • Unsecured loans – We generally fully charge off when the loan is 120 days past due. • Unsecured lines – We generally fully charge off when the loan is 180 days past due. • Other secured loans – We generally fully or partially charge down to net realizable value when the loan is 120 days past due. TROUBLED DEBT RESTRUCTURINGS In situations where, for economic or legal reasons related to a borrower’s financial difficulties, we grant a concession for other than an insignificant period of time to the borrower that we would not otherwise consider, the related loan is classified as a troubled debt restructuring (TDR). These modified terms may include interest rate reductions, principal forgiveness, term extensions, payment forbearance and other actions intended to minimize our economic loss and to avoid foreclosure or repossession of the collateral, if applicable. For modifications where we forgive principal, the entire amount of such principal forgiveness is immediately charged off. If the underwriting for a TDR modification did not include an evaluation of the borrower’s ability to repay, the loan is deemed collateral dependent. Other than resolutions such as foreclosures, sales and transfers to held-for-sale, we may remove loans held for investment from TDR classification, but only if they have been refinanced or restructured at market terms and qualify as a new loan. TROUBLED DEBT RESTRUCTURINGS AND OTHER RELIEF RELATED TO COVID-19 The Coronavirus, Aid, Relief, and Economic Security Act (the CARES Act) and the Interagency Statement on Loan Modifications and Reporting for Financial Institutions Working with Customers Affected by the Coronavirus (Revised) issued by federal regulators in April 2020 (the Interagency Statement) provide optional, temporary relief from accounting for certain loan modifications as TDRs. Based on guidance in the CARES Act and Interagency Statement, modifications related to the adverse effects of Coronavirus Disease 2019 (COVID-19) that meet certain criteria are exempt from TDR classification. We ceased applying TDR relief provided by the CARES Act upon the expiration of the CARES Act on January 1, 2022. During 2022, we continued to apply the TDR relief provided by the Interagency Statement for eligible COVID-related residential mortgage loan modifications. For COVID-19-related modifications in the form of payment deferrals or payment forbearance, delinquency status will not advance and loans that were accruing at the time the relief is provided will generally not be placed on nonaccrual status during the deferral period. Interest accrued during payment deferrals or payment forbearance may be included in the principal balance of the loans and charge-offs will generally be based on delinquency status after the loan exits the deferral or forbearance period. Loans that exit COVID-related deferrals or payment forbearance are placed on nonaccrual status if there is no evidence that the borrower can resume making payments or if the borrower requests additional modifications. FORECLOSED ASSETS Foreclosed assets obtained through our lending activities primarily include real estate. Generally, loans have been written down to their net realizable value prior to foreclosure. Any further reduction to their net realizable value is recorded with a charge to the ACL at foreclosure. We allow up to 90 days after foreclosure to finalize determination of net realizable value. Thereafter, changes in net realizable value are recorded to noninterest expense. The net realizable value of these assets is reviewed and updated periodically depending on the type of property. Certain government-guaranteed mortgage loans upon foreclosure are included in accounts receivable, not foreclosed assets. These receivables were loans insured by the Federal Housing Administration (FHA) or guaranteed by the Department of Veterans Affairs (VA) and are measured based on the balance expected to be recovered from the FHA or VA. Allowance for Credit Losses The ACL is management’s estimate of the current expected life-time credit losses in the loan portfolio and unfunded credit commitments, at the balance sheet date, excluding loans and unfunded credit commitments carried at fair value or held for sale. Additionally, we maintain an ACL for AFS and HTM debt securities, other financing receivables measured at amortized cost, and other off-balance sheet credit exposures. While we attribute portions of the allowance to specific financial asset classes (loan and debt security portfolios), loan portfolio segments (commercial and consumer) or major security type, the entire ACL is available to absorb credit losses of the Company. Our ACL process involves procedures to appropriately consider the unique risk characteristics of our financial asset classes, portfolio segments, and major security types. For each loan portfolio segment and each major HTM debt security type, losses are estimated collectively for groups of loans or securities with similar risk characteristics. For loans and securities that do not share similar risk characteristics with other financial assets, the losses are estimated individually, which generally includes our nonperforming large commercial loans and non-accruing HTM debt securities. For AFS debt securities, losses are estimated at the individual security level. Our ACL amounts are influenced by a variety of factors, including changes in loan and debt security volumes, portfolio credit quality, and general economic conditions. General economic conditions are forecasted using economic variables which will create volatility as those variables change over time. See Table 1.1 for key economic variables used for our loan portfolios. Table 1.1: Key Economic Variables Loan Portfolio Key economic variables Total commercial • Gross domestic product • Commercial real estate asset prices, where applicable • Unemployment rate Residential mortgage • Home price index • Unemployment rate Other consumer (including credit card, auto, and other consumer) • Unemployment rate Our approach for estimating expected life-time credit losses for loans and debt securities includes the following key components: • An initial loss forecast period of two years for all portfolio segments and classes of financing receivables and off-balance-sheet credit exposures. This period reflects management’s expectation of losses based on forward-looking economic scenarios over that time. We forecast multiple economic scenarios that generally include a base scenario with an optimistic (upside) and one or more pessimistic (downside) scenarios, which are weighted by management to estimate future credit losses. • Long-term average loss expectations estimated by reverting to the long-term average, on a linear basis, for each of the economic variables forecasted during the initial loss forecast period. These long-term averages are based on observatio

AFS And HTM Debt Securities [Abstract]
Available-for-Sale and Held-to-Maturity Debt Securities	Note 3: Available-for-Sale and Held-to-Maturity Debt Securities Table 3.1 provides the amortized cost, net of the allowance for credit losses (ACL) for debt securities, and fair value by major categories of available-for-sale (AFS) debt securities, which are carried at fair value, and held-to-maturity (HTM) debt securities, which are carried at amortized cost, net of the ACL. 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 for the years ended 2022 and 2021 was insignificant.

(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 December 31, 2022 and 2021. 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 December 31, 2022 Total portfolio (1) $ 113,594 99 % $ 297,144 99 % Breakdown by category: Securities of U.S. Treasury and federal agencies (2) $ 93,422 100 % $ 233,169 100 % Securities of U.S. states and political subdivisions 10,445 99 31,000 100 Collateralized loan obligations (3) 3,981 100 29,972 100 All other debt securities (4) 5,746 89 3,003 63 December 31, 2021 Total portfolio (1) $ 177,244 99 % $ 272,118 99 % Breakdown by category: Securities of U.S. Treasury and federal agencies (2) $ 145,547 100 % $ 205,453 100 % Securities of U.S. states and political subdivisions 16,917 99 32,704 100 Collateralized loan obligations (3) 5,708 100 31,128 100 All other debt securities (4) 9,072 88 2,833 64 (1) 99% and 98% were rated AA- and above at December 31, 2022 and 2021, respectively. (2) Includes federal agency mortgage-backed securities. (3) 100% were rated AA- and above at both December 31, 2022 and 2021. (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 December 31, 2022 and 2021. Charge-offs on debt securities were insignificant for the years ended December 31, 2022 and 2021. Purchased debt securities with credit deterioration (PCD) are not considered to be in nonaccrual status, as payments from issuers of these securities remain current. PCD securities were insignificant for the years ended December 31, 2022 and 2021. 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 allowance for credit losses.

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 this Report. Contractual Maturities Table 3.6 and Table 3.7 show the remaining contractual maturities, amortized cost, net of the ACL, fair value and weighted average effective yields of AFS and HTM debt securities, respectively. The remaining contractual principal maturities for mortgage-backed securities (MBS) do not consider prepayments. Remaining expected maturities will differ from contractual maturities because borrowers may have the right to prepay obligations before the underlying mortgages mature.

Loans and Related Allowance for Credit Losses	Note 5: Loans and Related Allowance for Credit Losses Table 5.1 presents total loans outstanding by portfolio segment and class of financing receivable. Outstanding balances include unearned income, net deferred loan fees or costs, and unamortized discounts and premiums. These amounts were less than 1% of our total loans outstanding at December 31, 2022 and 2021. 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 2022, we reversed accrued interest receivable of $29 million for our commercial portfolio segment and $143 million for our consumer portfolio segment, compared with $44 million and $175 million, respectively, for 2021.

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. Table 5.2: Non-U.S. Commercial Loans Outstanding (in millions) Dec 31, Dec 31, Commercial and industrial $ 78,981 77,365 Commercial real estate 7,619 8,652 Lease financing 670 680 Total non-U.S. commercial loans $ 87,270 86,697 Loan Concentrations Loan concentrations may exist when there are amounts loaned to borrowers engaged in similar activities or similar types of loans extended to a diverse group of borrowers that would cause them to be similarly impacted by economic or other conditions. Commercial and industrial loans and lease financing to borrowers in the financials except banks industry represented 15% and 16% of total loans at December 31, 2022 and 2021, respectively. At December 31, 2022 and 2021, we did not have concentrations representing 10% or more of our total loan portfolio in the commercial real estate (CRE) portfolios (real estate mortgage and real estate construction) by state or property type. Residential mortgage loans to borrowers in the state of California represented 12% of total loans at both December 31, 2022 and 2021. These California loans are generally diversified among the larger metropolitan areas in California, with no single area consisting of more than 4% of total loans at both December 31, 2022 and 2021. We continuously monitor changes in real estate values and underlying economic or market conditions for all geographic areas of our residential mortgage portfolio as part of our credit risk management process. Some of our residential mortgage loans include an interest-only feature as part of the loan terms. These interest-only loans were approximately 2% and 3% of total loans at December 31, 2022 and 2021, respectively. Substantially all of these interest-only loans at origination were considered to be prime or near prime. We do not offer option adjustable-rate mortgage (ARM) products, nor do we offer variable-rate mortgage products with fixed payment amounts, commonly referred to within the financial services industry as negative amortizing mortgage loans. Loan Purchases, Sales, and Transfers Table 5.3 presents the proceeds paid or received for purchases and sales of loans and transfers from loans held for investment to mortgages/loans held for sale. The table excludes loans for which we have elected the fair value option and government insured/guaranteed residential mortgage – first lien 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. Certain commitments either provide us with funding discretion or are subject to loan agreements with covenants regarding the financial performance of the customer or borrowing base formulas that must be met before we are required to fund the commitment. 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 December 31, 2022 and 2021, we had $1.8 billion and $1.5 billion, respectively, of outstanding issued commercial letters of credit. See Note 17 (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 excludes issued letters of credit and is presented net of commitments syndicated to others, including the fronting arrangements described above.

(2) Primarily includes securities-based lines of credit. Allowance for Credit Losses Table 5.5 presents the allowance for credit losses (ACL) for loans, which consists of the allowance for loan losses and the allowance for unfunded credit commitments. The ACL for loans decreased $179 million from December 31, 2021, reflecting reduced uncertainty around the economic impact of the COVID-19 pandemic on our loan portfolio. This decrease was partially offset by loan growth and a less favorable economic environment.

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 in a troubled debt restructuring (TDR). At December 31, 2022, we had $532.4 billion and $25.1 billion of pass and criticized commercial loans, respectively.

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. Credit quality information is provided with the year of origination for term loans. Revolving loans may convert to term loans as a result of a contractual provision in the original loan agreement or if modified in a TDR. 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. Table 5.9 provides the outstanding balances of our residential mortgage loans by our primary credit quality indicators. Payment deferral activities in the residential mortgage portfolio instituted in response to the COVID-19 pandemic could continue to delay the recognition of delinquencies for residential mortgage customers who otherwise would have moved into past due status. For additional information on customer accommodations in response to the COVID-19 pandemic, see Note 1 (Summary of Significant Accounting Policies) to Financial Statements in this Report. LTV refers to the ratio comparing the loan’s outstanding balance to the property’s collateral value. Combined LTV (CLTV) refers to the combination of first lien mortgage and junior lien mortgage (including unused line amounts for credit line products) ratios. We obtain LTVs and CLTVs using a cascade approach which first uses values provided by automated valuation models (AVMs) for the property. If an AVM is not available, then the value is estimated using the original appraised value adjusted by the change in Home Price Index (HPI) for the property location. If an HPI is not available, the original appraised value is used. The HPI value is normally the only method considered for high value properties, generally with an original value of $1 million or more, as the AVM values have proven less accurate for these properties. Generally, we obtain available LTVs and CLTVs on a quarterly basis. Certain loans do not have an LTV or CLTV due to a lack of industry data availability and portfolios acquired from or serviced by other institutions.

NONACCRUAL LOANS Table 5.12 provides loans on nonaccrual status. Nonaccrual loans may have an ACL or a negative allowance for credit losses from expected recoveries of amounts previously written off. Customer payment deferral activities in the residential mortgage portfolio instituted in response to the COVID-19 pandemic could continue to delay the recognition of nonaccrual loans for those residential mortgage customers who would have otherwise moved into nonaccrual status.

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 $1.0 billion and $694 million at December 31, 2022 and 2021, respectively, which included $771 million and $583 million, respectively, of loans that are government insured/guaranteed. Under the Consumer Financial Protection Bureau guidelines, we do not commence the foreclosure process on residential mortgage loans until after the loan is 120 days delinquent. Foreclosure procedures and timelines vary depending on whether the property address resides in a judicial or non-judicial state. Judicial states require the foreclosure to be processed through the state’s courts while non-judicial states are processed without court intervention. Foreclosure timelines vary according to state law. LOANS 90 DAYS OR MORE PAST DUE AND STILL ACCRUING Certain loans 90 days or more past due are still accruing, because they are (1) well-secured and in the process of collection or (2) residential mortgage or consumer loans exempt under regulatory rules from being classified as nonaccrual until later delinquency, usually 120 days past due. Table 5.13 shows loans 90 days or more past due and still accruing by class for loans not government insured/guaranteed. Table 5.13: Loans 90 Days or More Past Due and Still Accruing ($ in millions) Dec 31, Dec 31, Total: $ 4,340 5,358 Less: FHA insured/VA guaranteed (1) 3,005 4,699 Total, not government insured/guaranteed $ 1,335 659 By segment and class, not government insured/guaranteed: Commercial and industrial $ 583 206 Commercial real estate 134 29 Total commercial 717 235 Residential mortgage 28 49 Credit card 455 269 Auto 111 88 Other consumer 24 18 Total consumer 618 424 Total, not government insured/guaranteed $ 1,335 659 TROUBLED DEBT RESTRUCTURINGS (TDRs) When, for economic or legal reasons related to a borrower’s financial difficulties, we grant a concession for other than an insignificant period of time to a borrower that we would not otherwise consider, the related loan is classified as a TDR, the balance of which totaled $9.2 billion and $10.2 billion at December 31, 2022 and 2021, respectively. We do not consider loan resolutions such as foreclosure or short sale to be a TDR. In addition, COVID-19-related modifications are generally not classified as TDRs due to the relief under the CARES Act and the Interagency Statement. For additional information on the TDR relief, see Note 1 (Summary of Significant Accounting Policies) in this Report. We may require some consumer borrowers experiencing financial difficulty to make trial payments generally for a period of three to four months, according to the terms of a planned permanent modification, to determine if they can perform according to those terms. These arrangements represent trial modifications, which we classify and account for as TDRs. While loans are in trial payment programs, their original terms are not considered modified and they continue to advance through delinquency status and accrue interest according to their original terms. Commitments to lend additional funds on loans whose terms have been modified in a TDR amounted to $434 million and $431 million at December 31, 2022 and 2021, respectively. Table 5.14 summarizes our TDR modifications for the periods presented by primary modification type and includes the financial effects of these modifications. For those loans that modify more than once, the table reflects each modification that occurred during the period. Loans that both modify and are paid off or written-off within the period, as well as changes in recorded investment during the period for loans modified in prior periods, are not included in the table.

The reported amounts include loans remodified of $445 million, $737 million, and $1.5 billion for the years ended December 31, 2022, 2021 and 2020, respectively. (2) Other concessions include loans with payment (principal and/or interest) deferral, loans discharged in bankruptcy, loan renewals, term extensions and other interest and noninterest adjustments, but exclude modifications that also forgive principal and/or reduce the contractual interest rate. The reported amounts include loans that are new TDRs that may have COVID-19-related payment deferrals and exclude COVID-19-related payment deferrals on loans previously reported as TDRs given limited current financial effects other than payment deferral. (3) Charge-offs include write-downs of the investment in the loan in the period it is contractually modified. The amount of charge-off will differ from the modification terms if the loan has been charged down prior to the modification based on our policies. In addition, there may be cases where we have a charge-off/down with no legal principal modification. (4) Recorded investment related to interest rate reduction reflects the effect of reduced interest rates on loans with an interest rate concession as one of their concession types, which includes

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 amortization method to commercial MSRs and apply the fair value method to residential MSRs. The amortized cost of commercial MSRs was $1.2 billion, $1.3 billion and $1.3 billion, with an estimated fair value of $2.1 billion, $1.5 billion, and $1.4 billion, at December 31, 2022, 2021 and 2020, respectively. Table 6.1 presents the changes in MSRs measured using the fair value method. Table 6.1: Analysis of Changes in Fair Value MSRs Year ended December 31, (in millions) 2022 2021 2020 Fair value, beginning of period $ 6,920 6,125 11,517 Servicing from securitizations or asset transfers (1) 1,003 1,645 1,708 Sales and other (2) (614) (8) (32) Net additions 389 1,637 1,676 Changes in fair value: Due to valuation inputs or assumptions: Mortgage interest rates (3) 3,417 1,625 (3,946) Servicing and foreclosure costs (4) (17) (9) (175) Discount rates (5) 42 (56) 27 Prepayment estimates and other (6) (188) (390) (599) Net changes in valuation inputs or assumptions 3,254 1,170 (4,693) Changes due to collection/realization of expected cash flows (7) (1,253) (2,012) (2,375) Total changes in fair value 2,001 (842) (7,068) Fair value, end of period $ 9,310 6,920 6,125 (1) Includes impacts associated with exercising cleanup calls on securitizations and our right to repurchase delinquent loans from GNMA loan securitization pools. MSRs may increase upon repurchase due to servicing liabilities associated with these delinquent GNMA loans. (2) Includes sales and transfers of MSRs, which can result in an increase in MSRs if related to portfolios with servicing liabilities. For the year ended December 31, 2022, MSRs decreased $611 million due to the sale of interest-only strips related to excess servicing cash flows from agency residential mortgage-backed securitizations. (3) Includes prepayment rate changes as well as other valuation changes due to changes in mortgage interest rates. To reduce exposure to changes in interest rates, MSRs are economically hedged with derivative instruments. (4) Includes costs to service and unreimbursed foreclosure costs. (5) In 2022, we enhanced our approach for estimating the discount rates to a more dynamic methodology for market curves and volatility, which had a nominal impact. (6) Represents other changes in valuation model inputs or assumptions including prepayment rate estimation changes that are independent of mortgage interest rate changes. (7) Represents the reduction in the MSR fair value for the cash flows expected to be collected during the period, net of income accreted due to the passage of time. Table 6.2 provides key weighted-average assumptions used in the valuation of residential MSRs and sensitivity of the current fair value of residential MSRs to immediate adverse changes in those assumptions. Amounts for residential MSRs include purchased servicing rights as well as servicing rights resulting from the transfer of loans. See Note 15 (Fair Values of Assets and Liabilities) for additional information on key assumptions for residential MSRs. Table 6.2: Assumptions and Sensitivity of Residential MSRs ($ in millions, except cost to service amounts) Dec 31, 2022 Dec 31, 2021 Fair value of interests held $ 9,310 6,920 Expected weighted-average life (in years) 6.3 4.7 Key assumptions: Prepayment rate assumption (1) 9.4 % 14.7 Impact on fair value from 10% adverse change $ 288 356 Impact on fair value from 25% adverse change 688 834 Discount rate assumption 9.1 % 6.4 Impact on fair value from 100 basis point increase $ 368 276 Impact on fair value from 200 basis point increase 707 529 Cost to service assumption ($ per loan) 102 106 Impact on fair value from 10% adverse change 171 165 Impact on fair value from 25% adverse change 427 411 (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 the components of our managed servicing portfolio in Table 6.3 at unpaid principal balance for loans serviced and subserviced for others and at carrying value for owned loans serviced. Table 6.3: Managed Servicing Portfolio (in billions) Dec 31, 2022 Dec 31, 2021 Residential mortgage servicing: Serviced and subserviced for others $ 681 718 Owned loans serviced 273 276 Total residential servicing 954 994 Commercial mortgage servicing: Serviced and subserviced for others 577 597 Owned loans serviced 133 130 Total commercial servicing 710 727 Total managed servicing portfolio $ 1,664 1,721 Total serviced for others, excluding subserviced for others $ 1,246 1,304 MSRs as a percentage of loans serviced for others 0.84 % 0.63 Weighted average note rate (mortgage loans serviced for others) 4.30 3.82 At December 31, 2022 and 2021, we had servicer advances, net of an allowance for uncollectible amounts, of $2.5 billion and $3.2 billion, respectively. As the servicer of loans for others, we advance certain payments of principal, interest, taxes, insurance, and default-related expenses which are generally reimbursed within a short timeframe from cash flows from the trust, government-sponsored entities (GSEs), insurer or borrower. The credit risk related to these advances is limited since the reimbursement is generally senior to cash payments to investors. We also advance payments of taxes and insurance for our owned loans which are collectible from the borrower. We maintain an allowance for uncollectible amounts for advances on loans serviced for others that may not be reimbursed if the payments were not made in accordance with applicable servicing agreements or if the insurance or servicing agreements contain limitations on reimbursements. Servicing advances on owned loans are charged-off when deemed uncollectible. Table 6.4 presents the components of mortgage banking noninterest income.

Leasing Activity	Note 8: Leasing Activity The information below provides a summary of our leasing activities as a lessor and lessee. As a Lessor Table 8.1 presents the composition of our leasing revenue and Table 8.2 provides the components of our investment in lease financing. Noninterest income on leases, included in Table 8.1 is included in other noninterest income on our consolidated statement of income. Lease expense, included in other noninterest expense on our consolidated statement of income, was $750 million, $867 million, and $1.0 billion for the years ended December 31, 2022, 2021 and 2020, respectively. In 2021, we recognized an impairment charge of $268 million due to weakening demand for certain rail cars used for transportation of coal products. There were no impairments of rail cars as of December 31, 2022. Our rail car leasing business is in Corporate for our operating segment disclosures. For additional information on the accounting for impairment of operating lease assets, see Note 1 (Summary of Significant Accounting Policies).

Long-Term Debt	Dec. 31, 2022
Long-Term Debt, Current and Noncurrent [Abstract]
Long-Term Debt	Note 10: Long-Term Debt We issue long-term debt denominated in multiple currencies, predominantly in U.S. dollars. Our issuances, which are generally unsecured, have both fixed and floating interest rates. Principal is repaid upon contractual maturity, unless redeemed at our option at an earlier date. Interest is paid primarily on either a semi-annual or annual basis. As a part of our overall interest rate risk management strategy, we often use derivatives to manage our exposure to interest rate risk. We also use derivatives to manage our exposure to foreign currency risk. As a result, a majority of the long-term debt presented below is hedged in a fair value or cash flow hedge relationship. Table 10.1 presents a summary of our long-term debt carrying values, reflecting unamortized debt discounts and premiums, and hedge basis adjustments; unless we have elected the fair value option. See Note 14 (Derivatives) for additional information on qualifying hedge contracts and Note 15 (Fair Values of Assets and Liabilities) for additional information on fair value option elections. The interest rates displayed represent the range of contractual rates in effect at December 31, 2022. These interest rates do not include the effects of any associated derivatives designated in a hedge accounting relationship.

In October 2022, we redeemed all outstanding shares of our ESOP Preferred Stock in exchange for shares of the Company’s common stock. The redemption price was based on a fair market value of $618 million. Dividends on the ESOP Preferred Stock were cumulative from the date of initial issuance and were payable quarterly at annual rates based upon the year of issuance. Each share of ESOP Preferred Stock released from the unallocated reserve of the 401(k) Plan was converted into shares of our common stock based on the stated value of the ESOP Preferred Stock and the then current market price of our common stock. The ESOP Preferred Stock was also convertible at the option of the holder at any time, unless previously redeemed. We had the option to redeem the ESOP Preferred Stock at any time, in whole or in part, at a redemption price per share equal to the higher of (a) $1,000 per share plus accrued and unpaid dividends or (b) the fair market value, as defined in the Certificates of Designation for the ESOP Preferred Stock.

We repurchase shares to meet common stock issuance requirements for our benefit plans, share awards, conversion of our convertible securities, acquisitions and other corporate purposes. Various factors determine the amount and timing of our share repurchases, including our capital requirements, the number of shares we expect to issue for acquisitions and employee benefit plans, market conditions (including the trading price of our stock), and regulatory and legal considerations. These factors can change at any time, and there can be no assurance as to the number of shares we will repurchase or when we will repurchase them. Dividend Reinvestment and Common Stock Purchase Plans Participants in our dividend reinvestment and common stock direct purchase plans may purchase shares of our common stock at fair market value by reinvesting dividends and/or making optional cash payments under the plan’s terms. Employee Stock Plans We offer stock-based employee compensation plans as described below. For additional information on our accounting for stock-based compensation plans, see Note 1 (Summary of Significant Accounting Policies). LONG-TERM INCENTIVE PLANS We have granted restricted share rights (RSRs) and performance share awards (PSAs) as our primary long-term incentive awards. Holders of RSRs and PSAs may be entitled to receive additional RSRs and PSAs (dividend equivalents) or cash payments equal to the cash dividends that would have been paid had the RSRs or PSAs been issued and outstanding shares of common stock. RSRs and PSAs granted as dividend equivalents are subject to the same vesting schedule and conditions as the underlying award. Table 12.2 summarizes the major components of stock compensation expense and the related recognized tax benefit.

The total number of shares of common stock available for grant under the plans at December 31, 2022, was 129 million. Restricted Share Rights Holders of RSRs are entitled to the related shares of common stock at no cost generally vesting over three Table 12.3: Restricted Share Rights Number Weighted- average grant-date fair value Nonvested at January 1, 2022 51,604,179 $ 37.98 Granted 24,793,104 51.80 Vested (20,380,394) 42.30 Canceled or forfeited (2,779,746) 44.18 Nonvested at December 31, 2022 53,237,143 42.44 The weighted-average grant date fair value of RSRs granted during 2021 and 2020 was $32.99 and $42.53, respectively. At December 31, 2022, there was $986 million of total unrecognized compensation cost related to nonvested RSRs. The cost is expected to be recognized over a weighted-average period of 2.4 years. The total fair value of RSRs that vested during 2022, 2021 and 2020 was $1.0 billion, $902 million and $981 million, respectively. Performance Share Awards Holders of PSAs are entitled to the related shares of common stock at no cost subject to the Company’s achievement of specified performance criteria over a three are granted at a target number based on the Company’s performance. The number of awards that vest can be adjusted downward to zero and upward to a maximum of either 125% or 150% of target. The awards vest in the quarter after the end of the performance period. For PSAs whose performance period ended December 31, 2022, the determination of the number of performance shares that will vest will occur in first quarter 2023 after review of the Company’s performance by the Human Resources Committee of the Board. A summary of the status of our PSAs at December 31, 2022, and changes during 2022 is in Table 12.4, based on the performance adjustments recognized as of December 2022. Table 12.4: Performance Share Awards Number Weighted-average Nonvested at January 1, 2022 4,682,969 $ 36.63 Granted 1,011,080 $ 52.80 Vested (392,241) $ 50.50 Canceled or forfeited (793,471) $ 49.36 Nonvested at December 31, 2022 4,508,337 $ 36.81 (1) Reflects approval date fair value for grants subject to variable accounting. The weighted-average grant date fair value of performance awards granted during 2021 and 2020 was $32.76 and $40.39, respectively. At December 31, 2022, there was $33 million of total unrecognized compensation cost related to nonvested performance awards. The cost is expected to be recognized over a weighted-average period of 1.9 years. The total fair value of PSAs that vested during 2022, 2021 and 2020 was $19 million, $31 million and $35 million, respectively. Stock Options Stock options have not been issued in the last three years and no stock options were outstanding at December 31, 2022, 2021 and 2020. Director Awards We granted common stock awards to non-employee directors elected or re-elected at the annual meeting of stockholders on April 26, 2022. These stock awards vest immediately. Employee Stock Ownership Plan The Wells Fargo & Company 401(k) Plan (401(k) Plan) is a defined contribution plan with an Employee Stock Ownership Plan (ESOP) feature. We have previously loaned money to the 401(k) Plan to purchase ESOP Preferred Stock that was convertible into common stock over time as the loans were repaid. The Company’s annual contribution to the 401(k) Plan, as well as dividends received on unreleased shares, are used to make payments on the loans. As the loans are repaid, shares are released from the unallocated reserve of the 401(k) Plan. In October 2022, we redeemed all outstanding shares of our ESOP Preferred Stock in exchange for shares of the Company’s common stock. For additional information see Note 11 (Preferred Stock). Shares that are not yet released are reflected on our consolidated balance sheet as unearned ESOP shares. Released common stock is allocated to the 401(k) Plan participants and invested in the Wells Fargo ESOP Fund within the 401(k) Plan. Dividends on the allocated common shares reduce retained earnings, and the shares are considered outstanding for computing earnings per share. Dividends on the unreleased common stock or ESOP Preferred Stock do not reduce retained earnings, and the unreleased shares are not considered to be common stock equivalents for computing earnings per share. Table 12.5 presents the information related to the Wells Fargo ESOP Fund and the dividends paid to the 401(k) Plan.

Commitments and Contingencies Disclosure [Abstract]
Legal Actions	Note 13: 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. AUTOMOBILE LENDING MATTERS On April 20, 2018, the Company entered into consent orders with the Office of the Comptroller of the Currency (OCC) and the Consumer Financial Protection Bureau (CFPB) to resolve, among other things, investigations by the agencies into the Company’s compliance risk management program and its past practices involving certain automobile collateral protection insurance (CPI) policies and certain mortgage interest rate lock extensions. The consent orders require remediation to customers and the payment of a total of $1.0 billion in civil money penalties to the agencies. In July 2017, the Company announced a plan to remediate customers who may have been financially harmed due to issues related to automobile CPI policies purchased through a third-party vendor on their behalf. Multiple putative class actions alleging, among other things, unfair and deceptive practices relating to these CPI policies, were filed against the Company and consolidated into one multi-district litigation in the United States District Court for the Central District of California. As previously disclosed, the Company entered into a settlement to resolve the multi-district litigation. Shareholders also filed a putative securities fraud class action against the Company and its executive officers alleging material misstatements and omissions of CPI-related information in the Company’s public disclosures. In January 2020, the court dismissed this action as to all defendants except the Company and a former executive officer and limited the action to two alleged misstatements. Subject to court approval, the parties have entered into an agreement pursuant to which the Company will pay $300 million to resolve this action. In addition, the Company was subject to a class action in the United States District Court for the Central District of California alleging that customers were entitled to refunds related to the unused portion of guaranteed automobile protection (GAP) waiver or insurance agreements between the customer and dealer and, by assignment, the lender. As previously disclosed, the Company entered into a settlement to resolve the class action. Allegations related to the CPI and GAP programs were among the subjects of a shareholder derivative lawsuit in the United States District Court for the Northern District of California, which has been dismissed. In addition, federal and state government agencies, including the CFPB, have undertaken formal or informal inquiries, investigations, or examinations regarding these and other issues related to the origination, servicing, and collection of consumer auto loans, including related insurance products. On December 20, 2022, the Company entered into a consent order with the CFPB to resolve the CFPB’s investigations related to automobile lending, consumer deposit accounts, and mortgage lending. The consent order requires, among other things, remediation to customers and the payment of a $1.7 billion civil penalty to the CFPB. As previously disclosed, the Company entered into an agreement to resolve investigations by state attorneys general. COMMERCIAL LENDING SHAREHOLDER LITIGATION In October and November 2020, plaintiffs filed two putative securities fraud class actions, which were consolidated into one lawsuit pending in the United States District Court for the Northern District of California alleging that the Company and certain of its current and former officers made false and misleading statements or omissions regarding, among other things, the Company’s commercial lending underwriting practices, the credit quality of its commercial credit portfolios, and the value of its commercial loans, collateralized loan obligations and commercial mortgage-backed securities. In May 2022, the district court granted defendants’ motion to dismiss the lawsuit, which was appealed to the United States Court of Appeals for the Ninth Circuit. In January 2023, the parties voluntarily dismissed the appeal. COMPANY 401(K) PLAN MATTERS Federal government agencies, including the United States Department of Labor (Department of Labor), have undertaken reviews of 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. As previously disclosed, the Company entered into an agreement to resolve the Department of Labor’s review. 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 of these transactions. CONSENT ORDER DISCLOSURE LITIGATION Wells Fargo shareholders have brought a putative securities fraud class action in the United States District Court for the Southern District of New York alleging that the Company and certain of its current and former executive officers and directors made false or misleading statements regarding the Company’s efforts to comply with the February 2018 consent order with the Federal Reserve Board and the April 2018 consent orders with the CFPB and OCC. Allegations related to the Company’s efforts to comply with these three consent orders are also among the subjects of a shareholder derivative lawsuit filed in California state court. CONSUMER DEPOSIT ACCOUNT RELATED REGULATORY INVESTIGATIONS The CFPB has undertaken an investigation into whether customers were unduly harmed by the Company’s historical practices associated with the freezing (and, in many cases, closing) of consumer deposit accounts after the Company detected suspected fraudulent activity (by third parties or account holders) that affected those accounts. The CFPB has also undertaken an investigation into certain of the Company’s past disclosures to customers regarding the minimum qualifying debit card usage required for customers to receive a waiver of monthly service fees on certain consumer deposit accounts. As described above, on December 20, 2022, the Company entered into a consent order with the CFPB to resolve the CFPB’s investigations related to automobile lending, consumer deposit accounts, and mortgage lending. HIRING PRACTICES MATTERS Government agencies, including the United States Department of Justice and the United States Securities and Exchange Commission, have undertaken formal or informal inquiries or investigations regarding the Company’s hiring practices related to diversity. 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 shareholder derivative lawsuits filed 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, against Wells Fargo Bank, N.A., Wells Fargo & Company, Wachovia Bank, N.A., and Wachovia Corporation regarding the interchange fees associated with Visa and MasterCard payment card transactions. Visa, MasterCard, and several other banks and bank holding companies are also named as defendants in these actions. These actions have been consolidated in the United States District Court for the Eastern District of New York. The amended and consolidated complaint asserts claims against defendants based on alleged violations of federal and state antitrust laws and seeks damages as well as injunctive relief. Plaintiff merchants allege that Visa, MasterCard, and payment card issuing banks unlawfully colluded to set interchange rates. Plaintiffs also allege that enforcement of certain Visa and MasterCard rules and alleged tying and bundling of services offered to merchants are anticompetitive. Wells Fargo and Wachovia, along with other defendants and entities, are parties to Loss and Judgment Sharing Agreements, which provide that they, along with other entities, will share, based on a formula, in any losses from the Interchange Litigation. On July 13, 2012, Visa, MasterCard, and the financial institution defendants, including Wells Fargo, signed a memorandum of understanding with plaintiff merchants to resolve the consolidated class action and reached a separate settlement in principle of the consolidated individual actions. The settlement payments to be made by all defendants in the consolidated class and individual actions totaled approximately $6.6 billion before reductions applicable to certain merchants opting out of the settlement. The class settlement also provided for the distribution to class merchants of 10 basis points of default interchange across all credit rate categories for a period of eight consecutive months. The district court granted final approval of the settlement, which was appealed to the United States Court of Appeals for the Second Circuit by settlement objector merchants. Other merchants opted out of the settlement and are pursuing several individual actions. On June 30, 2016, the Second Circuit vacated the settlement agreement and reversed and remanded the consolidated action to the United States District Court for the Eastern District of New York for further proceedings. On November 23, 2016, prior class counsel filed a petition to the United States Supreme Court, seeking review of the reversal of the settlement by the Second Circuit, and the Supreme Court denied the petition on March 27, 2017. On November 30, 2016, the district court appointed lead class counsel for a damages class and an equitable relief class. The parties have entered into a settlement agreement to resolve the money damages class claims pursuant to which defendants will pay a total of approximately $6.2 billion, which includes approximately $5.3 billion of funds remaining from the 2012 settlement and $900 million in additional funding. The Company’s allocated responsibility for the additional funding is approximately $94.5 million. The court granted final approval of the settlement on December 13, 2019, which was appealed to the United States Court of Appeals for the Second Circuit by settlement objector merchants. On September 27, 2021, the district court granted the plaintiffs’ motion for class certification in the equitable relief case. Several of the opt-out and direct action litigations have been settled while others remain pending. MORTGAGE LENDING MATTERS Plaintiffs representing a class of mortgage borrowers filed separate putative class actions alleging that Wells Fargo improperly denied mortgage loan modifications or repayment plans to customers in the foreclosure process due to the overstatement of foreclosure attorneys’ fees that were included for purposes of determining whether a customer in the foreclosure process qualified for a mortgage loan modification or repayment plan. As previously disclosed, the Company entered into settlements to resolve the class actions, while the others were voluntarily dismissed. In addition, federal and state government agencies, including the CFPB, have undertaken formal or informal inquiries or investigations regarding these and other mortgage servicing matters. On September 9, 2021, the OCC assessed a $250 million civil money penalty against the Company regarding loss mitigation activities in the Company’s Home Lending business and insufficient progress in addressing requirements under the OCC’s April 2018 consent order. In addition, on September 9, 2021, the Company entered into a consent order with the OCC requiring the Company to improve the execution, risk management, and oversight of loss mitigation activities in its Home Lending business. As described above, on December 20, 2022, the Company entered into a consent order with the CFPB to resolve the CFPB’s investigations related to automobile lending, consumer deposit accounts, and mortgage lending. NOMURA/NATIXIS MORTGAGE-RELATED LITIGATION In August 2014 and August 2015, Nomura Credit & Capital Inc. (Nomura) and Natixis Real Estate Holdings, LLC (Natixis) filed a total of seven third-party complaints against Wells Fargo Bank, N.A., in New York state court. In the underlying first-party actions, Nomura and Natixis have been sued for alleged breaches of representations and warranties made in connection with residential mortgage-backed securities sponsored by them. In the third-party actions, Nomura and Natixis allege that Wells Fargo, as master servicer, primary servicer or securities administrator, failed to notify Nomura and Natixis of their own breaches, failed to properly oversee the primary servicers, and failed to adhere to accepted servicing practices. Natixis additionally alleges that Wells Fargo failed to perform default oversight duties. In March 2022, Wells Fargo entered into an agreement to settle the six actions filed by Nomura, and the actions have been voluntarily dismissed. In the remaining action filed by Natixis, Wells Fargo has asserted counterclaims alleging that Natixis failed to provide Wells Fargo notice of its representation and warranty breaches. In January 2023, Natixis and Wells Fargo reached an agreement in principle to settle their respective claims. OFAC RELATED INVESTIGATION The Company has self-identified an issue whereby certain foreign banks utilized a Wells Fargo software-based solution to conduct import/export trade-related financing transactions with countries and entities prohibited by the Office of Foreign Assets Control (OFAC) of the United States Department of the Treasury. We do not believe any funds related to these transactions flowed through accounts at Wells Fargo as a result of the aforementioned conduct. The Company has made voluntary self-disclosures to OFAC and has been cooperating with investigations or inquiries arising out of this matter by federal government agencies. The Company is in resolution discussions with certain of these agencies, although there can be no assurance as to the outcome of these discussions. RECORD-KEEPING INVESTIGATIONS The United States Securities and Exchange Commission and the United States Commodity Futures Trading Commission have undertaken investigations regarding the Company’s compliance with records retention requirements relating to business communications sent over unapproved electronic messaging channels. RETAIL SALES PRACTICES MATTERS Federal and state government agencies, including the United States Department of Justice (Department of Justice) and the United States Securities and Exchange Commission (SEC), have undertaken formal or informal inquiries or investigations arising out of certain retail sales practices of the Company that were the subject of settlements with the CFPB, the OCC, and the Office of the Los Angeles City Attorney announced by the Company on September 8, 2016. On February 21, 2020, the Company entered into an agreement with the Department of Justice to resolve the Department of Justice’s criminal investigation into the Company’s retail sales practices as well as a separate agreement to resolve the Department of Justice’s civil investigation. As part of the Department of Justice criminal settlement, no charges will be filed against the Company provided the Company abides by all the terms of the agreement. The Department of Justice criminal settlement also includes the Company’s agreement that the facts set forth in the settlement document constitute sufficient facts for the finding of criminal violations of statutes regarding bank records and personal information. On February 21, 2020, the Company also entered into an order to resolve the SEC’s investigation arising out of the Company’s retail sales practices. The SEC order contains a finding, to which the Company consented, that the facts set forth include violations of Section 10(b) of the Securities Exchange Act of 1934 and Rule 10b-5 thereunder. As part of the resolution of the Department of Justice and SEC investigations, the Company made payments totaling $3.0 billion. The Company has also entered into agreements to resolve other government agency investigations, including investigations by the state attorneys general. In addition, a number of lawsuits were filed by non-governmental parties seeking damages or other remedies related to these retail sales practices. As previously disclosed, the Company entered into various settlements to resolve these lawsuits. 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 and by IKB International and IKB Deutsche Industriebank 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 appealed the district court’s decision to the United States Court of Appeals for the Second Circuit. The Company previously settled two class actions filed by institutional investors and an action filed by the National Credit Union Administration with similar allegations. In addition, Park Royal I LLC and Park Royal II LLC have filed substantially similar lawsuits in New York state court alleging Wells Fargo Bank, N.A., as trustee, failed to take appropriate actions upon learning of defective mortgage loan documentation. 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. Wells Fargo filed a petition to remove the case to federal court, but the case was remanded back to state court. 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 $1.4 billion as of December 31, 2022. 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 14: Derivatives We use derivatives to manage exposure to market risk, including interest rate risk, credit risk and foreign currency risk, and to assist customers with their risk management objectives. We designate certain derivatives as hedging instruments in qualifying hedge accounting relationships (fair value or cash flow hedges). Our remaining derivatives consist of economic hedges that do not qualify for hedge accounting and derivatives held for customer accommodation trading or other purposes. Risk Management Derivatives Our asset/liability management approach to interest rate, foreign currency and certain other risks includes the use of derivatives, which are typically designated as fair value or cash flow hedges, or economic hedges. We use derivatives to help minimize significant, unplanned fluctuations in earnings, fair values of assets and liabilities, and cash flows caused by interest rate, foreign currency and other market risk volatility. This approach involves modifying the repricing characteristics of certain assets and liabilities so that changes in interest rates, foreign currency and other exposures, which may cause the hedged assets and liabilities to gain or lose fair value, do not have a significant adverse effect on the net interest margin, cash flows and earnings. In a fair value or economic hedge, the effect of change in fair value will generally be offset by the unrealized gain or loss on the derivatives linked to the hedged assets and liabilities. In a cash flow hedge, where we manage the variability of cash payments due to interest rate or foreign currency fluctuations by the effective use of derivatives linked to hedged assets and liabilities, the hedged asset or liability is not adjusted and the unrealized gain or loss on the derivative is recorded in other comprehensive income. Customer Accommodation Trading We also use various derivatives, including interest rate, commodity, equity, credit and foreign exchange contracts, as an accommodation to our customers as part of our trading businesses. These derivative transactions, which involve engaging in market-making activities or acting as an intermediary, are conducted in an effort to help customers manage their market risks. We usually offset our exposure from such derivatives by entering into other financial contracts, such as separate derivative or security transactions. These customer accommodations and any offsetting derivatives are treated as customer accommodation trading and other derivatives in our disclosures. Additionally, embedded derivatives that are required to be accounted for separately from their host contracts are included in the customer accommodation trading and other derivatives disclosures, as applicable. Table 14.1 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.

For additional information on Trading Activities, see Note 1 (Summary of Significant Accounting Policies). Balance Sheet Offsetting We execute substantially all of our derivative transactions under master netting arrangements. 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 14.2 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 18 (Pledged Assets and Collateral).

Counterparty valuation adjustments related to derivative assets were $372 million and $284 million and debit valuation adjustments related to derivative liabilities were $331 million and $158 million as of December 31, 2022 and 2021, 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. In addition, we use interest rate swaps, cross-currency swaps, cross-currency interest rate swaps and forward contracts to hedge against changes in fair value of certain investments in available-for-sale debt securities due to changes in interest rates, foreign currency rates, or both. 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 24 (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, and interest paid on certain floating-rate debt due to changes in the contractually specified interest rate. We also use cross-currency swaps to hedge variability in interest payments on fixed-rate foreign currency-denominated long-term debt due to changes in foreign exchange rates. We estimate $695 million pre-tax of deferred net losses related to cash flow hedges in OCI at December 31, 2022, will be reclassified into net interest income during the next twelve months. For cash flow hedges as of December 31, 2022, 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 10 years. For additional information on our accounting hedges, see Note 1 (Summary of Significant Accounting Policies). Table 14.3 and Table 14.4 show the net gains (losses) related to derivatives in cash flow and fair value hedging relationships, respectively.

(4) Carrying amount represents the amortized cost. Derivatives Not Designated as Hedging Instruments Derivatives not designated as hedging instruments include economic hedges and derivatives entered into for customer accommodation trading purposes. We use economic hedge derivatives to manage our exposure to interest rate risk, equity price risk, foreign currency risk, and credit risk. We also use economic hedge derivatives to mitigate the periodic earnings volatility caused by mismatches between the changes in fair value of the hedged item and hedging instrument recognized on our fair value accounting hedges. Changes in the fair values of derivatives used to economically hedge the deferred compensation plan are reported in personnel expense. Mortgage Banking Activities We use economic hedge derivatives in our mortgage banking business to hedge the risk of changes in the fair value of (1) certain residential MSRs measured at fair value, (2) residential mortgage LHFS, (3) derivative loan commitments, and (4) other interests held. The types of derivatives used include swaps, swaptions, constant maturity mortgages, forwards, Eurodollar and Treasury futures and options contracts. Loan commitments for mortgage loans that we intend to sell are considered derivatives. Residential MSRs, derivative loan commitments, certain residential mortgage LHFS, and our economic hedge derivatives are carried at fair value with changes in fair value included in mortgage banking noninterest income. See Note 6 (Mortgage Banking Activities) for additional information on this economic hedging activity and mortgage banking income. Customer Accommodation Trading and Other For customer accommodation trading purposes, we use swaps, futures, forwards, spots and options to assist our customers in managing their own risks, including interest rate, commodity, equity, foreign exchange, and credit contracts. These derivatives are not linked to specific assets and liabilities on our consolidated balance sheet or to forecasted transactions in an accounting hedge relationship and, therefore, do not qualify for hedge accounting. We also enter into derivatives for risk management that do not otherwise qualify for hedge accounting. They are carried at fair value with changes in fair value recorded in noninterest income. Customer accommodation trading and other derivatives also include embedded derivatives that are required to be accounted for separately from their host contract. We periodically issue hybrid long-term notes and certificates of deposit (CDs) where the performance of the hybrid instrument note is linked to an equity, commodity or currency index, or basket of such indices. These notes contain explicit terms that affect some or all of the cash flows or the value of the note in a manner similar to a derivative instrument and therefore are considered to contain an “embedded” derivative instrument. The indices on which the performance of the hybrid instrument is calculated are not clearly and closely related to the host debt instrument. The “embedded” derivative is separated from the host contract and accounted for as a derivative. Additionally, we may invest in hybrid instruments that contain embedded derivatives, such as credit derivatives, that are not clearly and closely related to the host contract. In such instances, we either elect fair value option for the hybrid instrument or separate the embedded derivative from the host contract and account for the host contract and derivative separately. Table 14.6 shows the net gains (losses), recognized by income statement lines, related to derivatives not designated as hedging instruments.

(2) In first quarter 2022, we prospectively reclassified certain equity securities and related economic hedge derivatives from “not held for trading activities” to “held for trading activities” to better reflect the business activity of those financial instruments. For additional information on Trading Activities, see Note 1 (Summary of Significant Accounting Policies). 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 14.7 provides details of sold credit derivatives. Table 14.7: Sold Credit Derivatives Notional amount (in millions) Protection sold Protection sold – non-investment grade December 31, 2022 Credit default swaps $ 12,733 1,860 Risk participation swaps 6,728 6,518 Total credit derivatives $ 19,461 8,378 December 31, 2021 Credit default swaps $ 8,033 1,982 Risk participation swaps 6,756 6,012 Total credit derivatives $ 14,789 7,994 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 of 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 14.8 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 15: 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 15.1 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 15.4 in this Note. We provide in Table 15.9 estimates of fair value for financial instruments that are not recorded at fair value, such as loans and debt liabilities carried at amortized cost. 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 this Report 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. Assets TRADING DEBT SECURITIES Trading debt securities are recorded at fair value on a recurring basis. These securities are valued using internal trader prices that are subject to independent price verification procedures, which includes comparing internal trader prices against multiple independent pricing sources, such as prices obtained from third-party pricing services, observed trades, and other approved market data. These pricing services compile prices from various sources and may apply matrix pricing for similar securities when no price is observable. We review pricing methodologies provided by pricing services to determine if observable market information is being used versus unobservable inputs. When evaluating the appropriateness of an internal trader price, compared with other independent pricing sources, considerations include the range and quality of available information and observability of trade data. These sources are used to evaluate the reasonableness of a trader price; however, valuing financial instruments involves judgments acquired from knowledge of a particular market. Substantially all of our trading debt securities are recorded using internal trader prices. AVAILABLE-FOR-SALE DEBT SECURITIES AFS debt securities are recorded at fair value on a recurring basis. Fair value measurement for AFS debt securities is based upon various sources of market pricing. Where available, we use quoted prices in active markets. When instruments are traded in secondary markets and quoted prices in active markets do not exist for such securities, we use prices obtained from third-party pricing services and, to a lesser extent, may use prices obtained from independent broker-dealers (brokers), collectively vendor prices. Substantially all of our AFS debt securities are recorded using vendor prices. See the “Level 3 Asset and Liability Valuation Processes – Vendor Developed Valuations” section in this Note for additional discussion of our processes when using vendor prices to record fair value of AFS debt securities, which includes those classified as Level 2 or Level 3 within the fair value hierarchy. When vendor prices are deemed inappropriate, they may be adjusted based on other market data or internal models. We also use internal models when no vendor prices are available. Internal models use discounted cash flow techniques or market comparable pricing techniques. LOANS HELD FOR SALE (LHFS) LHFS generally includes commercial and residential mortgage loans originated for sale in the securitization or whole loan market. A majority of residential LHFS, and our portfolio of commercial LHFS in our trading business, are recorded at fair value on a recurring basis. The remaining LHFS are held at LOCOM which may be written down to fair value on a nonrecurring basis. Fair value for LHFS that are not part of our trading business is based on quoted market prices, where available, or the prices for other mortgage whole loans with similar characteristics. We may use securitization prices that are adjusted for typical securitization activities including servicing value, portfolio composition, market conditions and liquidity. Fair value for LHFS in our trading business is based on pending transactions when available. Where market pricing data or pending transactions are not available, we use a discounted cash flow model to estimate fair value. LOANS Although loans are recorded at amortized cost, we record nonrecurring fair value adjustments to reflect write-downs that are based on the observable market price of the loan or current appraised value of the collateral less costs to sell. MORTGAGE SERVICING RIGHTS (MSRs) Residential MSRs are carried at fair value on a recurring basis. Commercial MSRs are carried at LOCOM and may be written down to fair value on a nonrecurring basis. MSRs do not trade in an active market with readily observable prices. We determine the fair value of MSRs using a valuation model that estimates the present value of expected future net servicing income. The model incorporates assumptions that market participants may use in estimating future net servicing income cash flows, including estimates of prepayment speeds (including housing price volatility for residential MSRs), discount rates, default rates, cost to service (including delinquency and foreclosure costs), escrow account earnings, contractual servicing fee income, ancillary income and late fees. DERIVATIVES Derivatives are recorded at fair value on a recurring basis. The fair value of exchange-traded derivatives that are actively traded and valued using quoted market prices are classified as Level 1 of the fair value hierarchy. The fair value of other derivatives, which predominantly relate to derivatives traded in over-the-counter (OTC) markets, are measured using internal valuation techniques, as quoted market prices are not readily available. These instruments are classified as Level 2 or Level 3 of the fair value hierarchy, depending on the significance of unobservable inputs in the valuation. Valuation techniques and inputs to internal models depend on the type of derivative and nature of the underlying rate, price or index upon which the value of the derivative is based. Key inputs can include yield curves, credit curves, foreign exchange rates, prepayment rates, volatility measurements and correlation of certain of these inputs. EQUITY SECURITIES Marketable equity securities and certain nonmarketable equity securities that we have elected to account for at fair value are recorded at fair value on a recurring basis. Our remaining nonmarketable equity securities are accounted for using the equity method, cost method or measurement alternative and can be subject to nonrecurring fair value adjustments to record impairment. Additionally, the carrying value of equity securities accounted for under the measurement alternative is also remeasured to fair value upon the occurrence of orderly observable transactions of the same or similar securities of the same issuer. We use quoted prices to determine the fair value of marketable equity securities, as the securities are publicly traded. Quoted prices are typically not available for nonmarketable equity securities. We therefore use other methods, generally market comparable pricing techniques, to determine fair value for such securities. We use all available information in making this determination, which includes observable transaction prices for the same or similar security, prices from third-party pricing services, broker quotes, trading multiples of comparable public companies, and discounted cash flow models. Where appropriate, we make adjustments to observed market data to reflect the comparative differences between the market data and the attributes of our equity security, such as differences with public companies and other investment-specific considerations like liquidity, marketability or differences in terms of the instruments. OTHER ASSETS Although other assets are generally recorded at amortized cost, we record nonrecurring fair value adjustments to reflect impairments or the impact of certain lease modifications. Other assets subject to nonrecurring fair value measurements include operating lease ROU assets, foreclosed assets and physical commodities. Fair value is generally based upon independent market prices or appraised values less costs to sell, or the use of a discounted cash flow model. Liabilities SHORT-SALE TRADING LIABILITIES Short-sale trading liabilities in our trading business are recorded at fair value on a recurring basis and are measured using quoted prices in active markets, where available. When quoted prices for the same instruments are not available or markets are not active, fair values are estimated using recent trades of similar securities. LONG-TERM DEBT Although long-term debt is generally recorded at amortized cost, we have elected the fair value option for certain structured notes issued by our trading business. Fair values for these instruments are estimated using a discounted cash flow model that includes both the embedded derivative and debt portions of the notes. The discount rate used in these discounted cash flow models also incorporates the impact of our credit spread, which is based on observable spreads in the secondary bond market. Level 3 Asset and Liability Valuation Processes We generally determine fair value of our Level 3 assets and liabilities by using internal models and, to a lesser extent, prices obtained from vendors. Our valuation processes vary depending on which approach is utilized. INTERNAL MODEL VALUATIONS Certain Level 3 fair value estimates are based on internal models, such as discounted cash flow or market comparable pricing techniques. Some of the inputs used in these valuations are unobservable. Unobservable inputs are generally derived from or can be correlated to historic performance of similar portfolios or previous market trades in similar instruments where particular unobservable inputs may be implied. We attempt to correlate each unobservable input to historical experience and other third-party data where available. Internal models are subject to review prescribed within our model risk management policies and procedures, which include model validation. Model validation helps ensure our models are appropriate for their intended use and appropriate controls exist to help mitigate risk of invalid valuations. Model validation assesses the adequacy and appropriateness of our models, including reviewing its key components, such as inputs, processing components, logic or theory, output results and supporting model documentation. Validation also includes ensuring significant unobservable model inputs are appropriate given observable market transactions or other market data within the same or similar asset classes. We also have ongoing monitoring procedures in place for our Level 3 assets and liabilities that use internal valuation models. These procedures, which are designed to provide reasonable assurance that models continue to perform as expected, include: • ongoing analysis and benchmarking to market transactions and other independent market data (including pricing vendors, if available); • back-testing of modeled fair values to actual realized transactions; and • review of modeled valuation results against expectations, including review of significant or unusual fluctuations in value. We update model inputs and methodologies periodically to reflect these monitoring procedures. Additionally, existing models are subject to periodic reviews and we perform full model revalidations as necessary. Internal valuation models are subject to ongoing review by the appropriate principal line of business or enterprise function and monitoring oversight by Independent Risk Management. Independent Risk Management, through its Model Risk function, provides independent oversight of model risk management, and its responsibilities include governance, validation, periodic review, and monitoring of model risk across the Company and providing periodic reports to management and the Board’s Risk Committee. VENDOR-DEVELOPED VALUATIONS We routinely obtain pricing from third-party vendors to value our assets or liabilities. In certain limited circumstances, this includes assets and liabilities that we classify as Level 3. We have processes in place to approve and periodically review third-party vendors to assess whether information obtained and valuation techniques used are appropriate. This review may consist of, among other things, obtaining and evaluating control reports issued and pricing methodology materials distributed. We monitor and review vendor prices on an ongoing basis to evaluate whether the fair values are reasonable and in line with market experience in similar asset classes. While the inputs used to determine fair value are not provided by the pricing vendors, and therefore unavailable for our review, we perform one or more of the following procedures to validate the pricing information and determine appropriate classification within the fair value hierarchy: • comparison to other pricing vendors (if available); • variance analysis of prices; • corroboration of pricing by reference to other independent market data, such as market transactions and relevant benchmark indices; • review of pricing by Company personnel familiar with market liquidity and other market-related conditions; and • investigation of prices on a specific instrument-by-instrument basis.

Table 15.3 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 (see discussion in the “Level 3 Asset and Liability Valuation Processes” section within this Note regarding vendor-developed valuations). 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.

The internal valuation techniques used for our Level 3 assets and liabilities, as presented in Table 15.3, are described as follows: • Discounted cash flow – Discounted cash flow valuation techniques generally consist of developing an estimate of future cash flows that are expected to occur over the life of an instrument and then discounting those cash flows at a rate of return that results in the fair value amount. • Market comparable pricing – Market comparable pricing valuation techniques are used to determine the fair value of certain instruments by incorporating known inputs, such as recent transaction prices, pending transactions, financial metrics of comparable companies, or prices of other similar investments that require significant adjustment to reflect differences in instrument characteristics. • Option model – Option model valuation techniques are generally used for instruments in which the holder has a contingent right or obligation based on the occurrence of a future event, such as the price of a referenced asset going above or below a predetermined strike price. Option models estimate the likelihood of the specified event occurring by incorporating assumptions such as volatility estimates, price of the underlying instrument and expected rate of return. The unobservable inputs presented in the previous tables are those we consider significant to the fair value of the Level 3 asset or liability. We consider unobservable inputs to be significant if by their exclusion the fair value of the Level 3 asset or liability would be impacted by a predetermined percentage change. We also consider qualitative factors, such as nature of the instrument, type of valuation technique used, and the significance of the unobservable inputs relative to other inputs used within the valuation. Following is a description of the significant unobservable inputs provided in the table. • Comparability adjustment – is an adjustment made to observed market data, such as a transaction price to reflect dissimilarities in underlying collateral, issuer, rating, or other factors used within a market valuation approach, expressed as a percentage of an observed price. • Conversion factor – is the risk-adjusted rate in which a particular instrument may be exchanged for another instrument upon settlement, expressed as a percentage change from a specified rate. • Correlation factor – is the likelihood of one instrument changing in price relative to another based on an established relationship expressed as a percentage of relative change in price over a period over time. • Cost to service – is the expected cost per loan of servicing a portfolio of loans, which includes estimates for unreimbursed expenses (including delinquency and foreclosure costs) that may occur as a result of servicing such loan portfolios. • Default rate – is an estimate of the likelihood of not collecting contractual amounts owed expressed as a constant default rate (CDR). • Discount rate – is a rate of return used to calculate the present value of the future expected cash flow to arrive at the fair value of an instrument. The discount rate consists of a benchmark rate component and a risk premium component. The benchmark rate component, for example, OIS, London Interbank Offered Rate (LIBOR), Secured Overnight Financing Rate (SOFR) or U.S. Treasury rates, is generally observable within the market and is necessary to appropriately reflect the time value of money. The risk premium component reflects the amount of compensation market participants require due to the uncertainty inherent in the instruments’ cash flows resulting from risks such as credit and liquidity. • Fall-out factor – is the expected percentage of loans associated with our interest rate lock commitment portfolio that are likely of not funding. • Initial-value servicing – is the estimated value of the underlying loan, including the value attributable to the embedded servicing right, expressed in basis points of outstanding unpaid principal balance. • Loss severity – is the estimated percentage of contractual cash flows lost in the event of a default. • Multiples – are financial ratios of comparable public companies, such as ratios of enterprise value or market value of equity to earnings before interest, depreciation, and amortization (EBITDA), revenue, net income or book value, adjusted to reflect dissimilarities in operational, financial, or marketability to the comparable public company used in a market valuation approach. • Prepayment rate – is the estimated rate at which forecasted prepayments of principal of the related loan or debt instrument are expected to occur, expressed as a constant prepayment rate (CPR). • Volatility factor – is the extent of change in price an item is estimated to fluctuate over a specified period of time expressed as a percentage of relative change in price over a period over time. • Weighted average life – is the weighted average number of years an investment is expected to remain outstanding based on its expected cash flows reflecting the estimated date the i

Securitizations and Variable Interest Entities [Abstract]
Securitizations and Variable Interest Entities	Note 16: 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 U.S. GOVERNMENT SPONSORED ENTITIES AND TRANSACTIONS WITH GINNIE MAE In the normal course of business we sell originated and purchased residential and commercial mortgage loans to government-sponsored entities (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 Federal Housing Administration (FHA) or guaranteed by the Department of Veterans Affairs (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 GNMA loan securitization pools, which becomes exercisable when three scheduled loan payments remain unpaid by the borrower. During the years ended December 31, 2022, 2021 and 2020, we repurchased loans of $2.2 billion, $4.6 billion, and $30.3 billion, respectively, which predominantly represented repurchases of government insured loans. We recorded assets and related liabilities of $743 million and $107 million at December 31, 2022 and 2021, respectively, where we did not exercise our option to repurchase eligible loans. 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 December 31, 2022 and 2021, our liability for these repurchase and recourse arrangements was $167 million and $173 million, respectively, and the maximum exposure to loss was $13.8 billion and $13.3 billion at December 31, 2022 and 2021, 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 residential and commercial 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, account for the transfers as sales and do not consolidate the VIE. We also typically retain the right to service the loans and may hold other beneficial interests issued by the VIEs, 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 and 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 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 16.1 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, securities, and loans. 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. Substantially all transfers were related to residential mortgage securitizations with the GSEs or GNMA and resulted in no gain or loss because the loans are measured at fair value on a recurring basis. Additionally, we may transfer certain government insured loans that we previously repurchased. These 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. Table 16.1: Transfers with Continuing Involvement Year ended December 31, 2022 2021 2020 (in millions) Residential mortgages Commercial mortgages Residential mortgages Commercial mortgages Residential mortgages Commercial mortgages Assets sold $ 75,582 13,735 157,063 18,247 177,441 11,744 Proceeds from transfer (1) 75,634 13,963 157,852 18,563 177,478 12,034 Net gains (losses) on sale 52 228 789 316 37 290 Continuing involvement (2): Servicing rights recognized $ 966 128 1,636 166 1,808 161 Securities recognized (3) 2,062 189 23,188 173 31,567 112 Loans recognized — — 926 — — — (1) Represents cash proceeds and the fair value of non-cash beneficial interests recognized at securitization settlement.

(3) Represents debt securities obtained at securitization settlement held for investment purposes that are classified as available-for-sale or held-to-maturity, which predominantly relate to agency securities. Excludes trading debt securities held temporarily for market-marking purposes, which are sold to third parties at or shortly after securitization settlement, of $19.0 billion, $40.7 billion, and $37.6 billion, during the years ended December 31, 2022, 2021 and 2020, 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. During the years ended December 31, 2022, 2021 and 2020, we received cash flows of $456 million, $686 million, and $198 million, respectively, related to principal and interest payments on these securities and loans, which exclude cash flows related to trading activities and to the sale of our student loan portfolio. Table 16.2 presents the key weighted-average assumptions we used to initially measure residential MSRs recognized during the periods presented. Table 16.2: Residential MSRs – Assumptions at Securitization Date Year ended December 31, 2022 2021 2020 Prepayment rate (1) 12.4 % 13.7 15.4 Discount rate 8.0 5.9 6.5 Cost to service ($ per loan) $ 110 91 96 (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 15 (Fair Values of Assets and Liabilities) and Note 6 (Mortgage Banking Activities) for additional information on key assumptions for residential MSRs. SALE OF STUDENT LOAN PORTFOLIO In the year ended December 31, 2021, we sold $9.5 billion of student loans, servicing-released. For the same period, we received $9.9 billion in proceeds from the sales and recognized $355 million of gains, which are included in other noninterest income on our consolidated statement of income. In connection with the sales, we provided $3.8 billion of collateralized loan financing to a third-party sponsored VIE, and received cash flows of $3.8 billion which fully repaid these loans. We do not consolidate the VIE as we do not have power over the significant activities of the entity. 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. We transferred $17.0 billion, $39.6 billion, and $77.2 billion of securities to resecuritization VIEs during the years ended December 31, 2022, 2021 and 2020, respectively. These amounts are not included in Table 16.1. Related total VIE assets were $112.0 billion and $117.7 billion at December 31, 2022 and 2021, respectively. As of December 31, 2022 and 2021, we held $793 million and $817 million of securities, respectively, of which $428 million and $607 million related to resecuritizations transacted during the years ended December 31, 2022 and 2021, respectively. Sold or Securitized Loans Serviced for Others Table 16.3 presents information about loans that we sold or securitized in which we have ongoing involvement as servicer. Delinquent loans include loans 90 days or more past due and loans in bankruptcy, regardless of delinquency status. 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 16.3 excludes mortgage loans in GSE or GNMA securitizations of $704.5 billion and $736.8 billion at December 31, 2022 and 2021, respectively. Delinquent loans and foreclosed assets related to GSEs and GNMA were $4.6 billion and $10.3 billion at December 31, 2022 and 2021, respectively. Table 16.3: Sold or Securitized Loans Serviced for Others Net charge-offs Total loans Delinquent loans Year ended December 31, (in millions) Dec 31, 2022 Dec 31, 2021 Dec 31, 2022 Dec 31, 2021 2022 2021 Commercial $ 67,029 65,655 912 1,617 49 143 Residential 9,201 9,288 501 764 14 22 Total off-balance sheet sold or securitized loans $ 76,230 74,943 1,413 2,381 63 165 (1) Includes $274 million and $403 million of commercial foreclosed assets and $25 million and $29 million of residential foreclosed assets at December 31, 2022 and 2021, respectively. Transactions with Unconsolidated VIEs MORTGAGE LOAN SECURITIZATIONS Table 16.4 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 16.4 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 16.4 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 16.4, “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 16.4, 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 tax credits and other tax benefits. 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 $18.7 billion and $17.0 billion at December 31, 2022 and 2021, respectively. We also had loans to tax credit VIEs with a carrying value of $2.0 billion and $1.9 billion at December 31, 2022 and 2021, respectively. Our maximum exposure to loss for tax credit VIEs at December 31, 2022 and 2021, was $28.0 billion and $24.7 billion, respectively. Our maximum exposure to loss included total unfunded equity and lending commitments of $7.3 billion and $5.6 billion at December 31, 2022 and 2021, respectively. See Note 17 (Guarantees and Other Commitments) for additional information about unfunded capital commitments. Our affordable housing equity investments qualify for the low-income housing tax credit (LIHTC). For these investments we are periodically required to provide additional financial support during the investment period, or at the discretion of project sponsors. A liability is recognized for unfunded commitments that are both legally binding and probable of funding. These commitments are predominantly funded within three years of initial investment. Our liability for affordable housing equity investment unfunded commitments was $4.8 billion at December 31, 2022, and $4.9 billion at December 31, 2021, and was included in long-term debt on our consolidated balance sheet. Table 16.5 summarizes the amortization of our LIHTC investments and the related tax credits and other tax benefits that are recognized in income tax expense/(benefit) on our consolidated statement of income. Table 16.5: LIHTC Investments Year ended December 31, (in millions) 2022 2021 2020 Proportional amortization of investments $ 1,549 1,545 1,407 Tax credits and other tax benefits (1,834) (1,783) (1,639) Net expense/(benefit) recognized within income tax expense $ (285) (238) (232) 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 may securitize dealer floor plan loans in a revolving master trust entity. As servicer and residual interest holder, we control the key decisions of the trust and consolidate the entity. The total VIE assets held by the master trust represent a majority of the total VIE assets presented for this category in Table 16.6. 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 service the underlying collateral. OTHER VIE STRUCTURES Other VIEs are predominantly related to municipal tender option bond (MTOB) transactions. MTOBs are vehicles to finance the purchase of municipal bonds through the issuance of short-term debt to investors. Our involvement with MTOBs includes serving as the residual interest holder, which provides control over the key decisions of the VIE, as well as the remarketing agent or liquidity provider related to the debt issued to investors. We may also securitize nonconforming mortgage loans, in which our involvement includes servicer of the underlying assets and holder of subordinate or senior securities issued by the VIE. During second quarter 2022, we purchased the outstanding mortgage loans from the VIEs and extinguished the related debt associated with such securitizations. Table 16.6 presents a summary of financial assets and liabilities of our consolidated VIEs. The carrying value represents assets and liabilities recorded 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.

Guarantees and Other Commitment

Guarantees [Abstract]
Guarantees and Other Commitments	Note 17: 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. Table 17.1 shows carrying value and maximum exposure to loss on our guarantees. Table 17.1: 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 December 31, 2022 Standby letters of credit (1) $ 112 14,014 4,694 3,058 53 21,819 7,071 Direct pay letters of credit (1) 13 1,593 2,734 465 5 4,797 1,283 Loans and LHFS sold with recourse (2) 16 322 1,078 3,408 8,906 13,714 11,399 Exchange and clearing house guarantees (3) — 4,623 — — — 4,623 — Other guarantees and indemnifications (4) — 548 1 10 201 760 515 Total guarantees $ 141 21,100 8,507 6,941 9,165 45,713 20,268 December 31, 2021 Standby letters of credit (1) $ 119 13,816 5,260 1,572 460 21,108 6,939 Direct pay letters of credit (1) 6 1,597 2,137 1,283 4 5,021 1,373 Loans and LHFS sold with recourse (2) 20 71 943 3,610 8,650 13,274 11,268 Exchange and clearing house guarantees (3) — — — — 8,100 8,100 — Other guarantees and indemnifications (4) — 797 2 12 263 1,074 756 Total guarantees $ 145 16,281 8,342 6,477 17,477 48,577 20,336 (1) Standby and direct pay letters of credit are reported net of syndications and participations. (2) Represents recourse provided, predominantly to the GSEs, on loans sold under various programs and arrangements. (3) In 2022, we changed our presentation for maximum exposure to loss for these guarantees. As the agreements that include these guarantees automatically renew annually, we believe presentation of these amounts within the expires in one year or less category better aligns with the committed term. (4) Includes indemnifications provided to certain third-party clearing agents. Estimated maximum exposure to loss was $157 million and $216 million with related collateral of $1.3 billion and $2.3 billion as of December 31, 2022 and 2021, respectively. 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 17.1 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 17.1, 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. STANDBY LETTERS OF CREDIT We issue standby letters of credit, which include performance and financial guarantees, for customers in connection with contracts between our customers and third parties. Standby letters of credit are conditional lending commitments where we are obligated to make payment to a third party on behalf of a customer if the customer fails to meet their contractual obligations. Total maximum exposure to loss includes the portion of multipurpose lending facilities for which we have issued standby letters of credit under the commitments. DIRECT PAY LETTERS OF CREDIT We issue direct pay letters of credit to serve as credit enhancements for certain bond issuances. Beneficiaries (bond trustees) may draw upon these instruments to make scheduled principal and interest payments, redeem all outstanding bonds because a default event has occurred, or for other reasons as permitted by the agreement. 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. Written put options give the counterparty the right to sell to us an underlying instrument held by the counterparty at a specified price by a specified date. While these derivative transactions expose us to risk if the option is exercised, we manage this risk by entering into offsetting trades or by taking short positions in the underlying instrument. We offset market risk related to options written to customers with cash securities or other offsetting derivative transactions. Additionally, for certain of these contracts, we require the counterparty to pledge the underlying instrument as collateral for the transaction. Our ultimate obligation under written options is based on future market conditions and is only quantifiable at settlement. 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 a liability of $15 million, and an asset of $280 million at December 31, 2022 and 2021, 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 December 31, 2022, the maximum exposure to loss was $23.4 billion, with $21.3 billion expiring in three years or less compared with $17.2 billion and $16.7 billion, respectively, at December 31, 2021. See Note 14 (Derivatives) for additional information regarding written derivative contracts. LOANS AND LHFS SOLD WITH RECOURSE In certain sales and securitizations of loans, including mortgage loans, we provide recourse to the buyer whereby we are required to indemnify the buyer for any loss on the loan up to par value plus accrued interest. We provide recourse, predominantly to GSEs, on loans sold under various programs and arrangements. Substantially all of these programs and arrangements require that we share in the loans’ credit exposure for their remaining life by providing recourse to the GSE, up to 33.33% of actual losses incurred on a pro-rata basis in the event of borrower default. Under the remaining recourse programs and arrangements, if certain events occur within a specified period of time from transfer date, we have to provide limited recourse to the buyer to indemnify them for losses incurred for the remaining life of the loans. The maximum exposure to loss reported in Table 17.1 represents the outstanding principal balance of the loans sold or securitized that are subject to recourse provisions or the maximum losses per the contractual agreements. However, we believe the likelihood of loss of the entire balance due to these recourse agreements is remote, and amounts paid can be recovered in whole or in part from the sale of collateral. We also provide representation and warranty guarantees on loans sold under the various recourse programs and arrangements. Our loss exposure relative to these guarantees is separately considered and provided for, as necessary, in determination of our liability for loan repurchases due to breaches of representation and warranties. EXCHANGE AND CLEARING HOUSE GUARANTEES We are members of several securities and derivatives exchanges and clearing houses, both in the U.S. and in countries outside the U.S., that we use to clear our trades and those of our customers. It is common that all members in these organizations are required to collectively guarantee the performance of other members and of the organization. Our obligations under the guarantees are generally a pro-rata share based on either a fixed amount or a multiple of the guarantee fund we are required to maintain with these organizations. Some membership rules require members to assume a pro-rata share of losses resulting from another member’s default or from non-member default losses after applying the guarantee fund. We have not recorded a liability for these arrangements as of the dates presented in Table 17.1 because we believe the likelihood of loss is remote. OTHER GUARANTEES AND INDEMNIFICATIONS We have contingent performance arrangements related to various customer relationships and lease transactions. We are required to pay the counterparties to these agreements if third parties default on certain obligations. Under certain factoring arrangements, we may be required to purchase trade receivables from third parties, if receivable debtors default on their payment obligations. We use certain third-party clearing agents to clear and settle transactions on behalf of some of our institutional brokerage customers. We indemnify the clearing agents against loss that could occur for non-performance by our customers on transactions that are not sufficiently collateralized. Transactions subject to the indemnifications may include customer obligations related to the settlement of margin accounts and short positions, such as written call options and securities borrowing transactions. We enter into other types of indemnification agreements in the ordinary course of business under which we agree to indemnify third parties against any damages, losses and expenses incurred in connection with legal and other proceedings arising from relationships or transactions with us. These relationships or transactions include those arising from service as a director or officer of the Company, underwriting agreements relating to our securities, acquisition agreements and various other business transactions or arrangements. Because the extent of our obligations under these agreements depends entirely upon the occurrence of future events, we are unable to determine our potential future liability under these agreements. We do, however, record a liability for residential mortgage loans that we expect to repurchase pursuant to various representations and warranties. 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. If we are unable to collect the amounts from the merchant, we incur a loss for the refund to the cardholder. We are secondarily obligated to make a refund for transactions involving sponsored merchant processing servicers. We generally have a low likelihood of loss in connection with our merchant processing services because most products and services are delivered when purchased and amounts are generally refunded when items are returned to the merchant. In addition, we may reduce our risk in connection with these transactions by withholding future payments and requiring cash or other collateral. 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 December 31, 2022, our potential maximum exposure was approximately $759.6 billion, and related losses, including those from our joint venture entity, were insignificant. GUARANTEES OF SUBSIDIARIES In the normal course of business, the Parent may provide counterparties with guarantees related to its subsidiaries’ obligations. These obligations are included in the Company’s consolidated balance sheet or are reflected as off-balance sheet commitments, and therefore, the Parent has not recognized a separate liability for these guarantees. 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 $948 million and $1.2 billion at December 31, 2022 and 2021, respectively. These guarantees rank on parity with all of the Parent’s other unsecured and unsubordinated indebtedness. The assets of the Parent consist primarily of equity in its subsidiaries, and the Parent is a separate and distinct legal entity from its subsidiaries. As a result, the Parent’s ability to address claims of holders of these debt securities against the Parent under the guarantee depends on the Parent’s receipt of dividends, loan payments and other funds from its subsidiaries. If any of the Parent’s subsidiaries becomes insolvent, the direct creditors of that subsidiary will have a prior claim on that subsidiary’s assets. The rights of the Parent and the rights of the Parent’s creditors will be subject to that prior claim unless the Parent is also a direct creditor of that subsidiary. For additional information regarding other restrictions on the Parent’s ability to receive dividends, loan payments and other funds from its subsidiaries, see Note 25 (Regulatory Capital Requirements and Other Restrictions. OTHER COMMITMENTS To meet the financing needs of our customers, we may enter into commitments to purchase debt and equity securities to provide capital for their funding, liquidity or other future needs. As of December 31, 2022 and 2021, we had commitments to purchase debt securities of $100 million and $18 million and commitments to purchase equity securities of $3.8 billion and $2.4 billion, respectively. As part of maintaining our memberships in certain clearing organizations, we are required to stand ready to provide liquidity to sustain market clearing activity in the event unforeseen events occur or are deemed likely to occur. Certain of these obligations are guarantees of other members’ performance and accordingly are included in Table 17.1 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 $19.9 billion and $11.0 billion as of December 31, 2022 and 2021, respectively. The amount of our unfunded contractual commitments for repurchase and securities lending agreements was $1.6 billion and $1.3 billion as of December 31, 2022 and 2021, 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).

Transfers and Servicing [Abstract]
Pledged Assets and Collateral	Note 18: Pledged Assets and Collateral Pledged Assets Table 18.1 provides the carrying amount of on-balance sheet pledged assets as well as the fair value of other pledged collateral not recognized on our consolidated balance sheet, which we have received from third parties, have the right to repledge and have repledged. These amounts include assets pledged in transactions accounted for as secured borrowings, which are presented parenthetically on our consolidated balance sheet. TRADING RELATED ACTIVITY Our trading businesses may pledge debt and equity securities in connection with securities sold under agreements to repurchase (repurchase agreements) and securities lending arrangements. The collateral that we pledge related to our trading activities may include our own collateral as well as collateral that we have received from third parties and have the right to repledge. All of the collateral we pledge related to trading activity is eligible to be repledged or sold by the secured party. NON-TRADING RELATED ACTIVITY As part of our liquidity management strategy, we may pledge loans, debt securities, and other financial assets to secure trust and public deposits, borrowings and letters of credit from Federal Home Loan Banks (FHLBs) and the Board of Governors of the Federal Reserve System (FRB) and for other purposes as required or permitted by law or insurance statutory requirements. Substantially all of the non-trading activity pledged collateral is not eligible to be repledged or sold by the secured party. VIE RELATED We pledge assets in connection with various types of transactions entered into with VIEs. These pledged assets can only be used to settle the liabilities of those entities. We also have loans recorded on our consolidated balance sheet which represent certain delinquent loans that are eligible for repurchase from GNMA loan securitizations. See Note 16 (Securitizations and Variable Interest Entities) for additional information on consolidated VIE assets.

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 18.2 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, and those with a single 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. Generally, these agreements require collateral to exceed the asset or liability recognized on the balance sheet. The following table includes the amount of collateral pledged or received related to exposures subject to enforceable MRAs or MSLAs. While these agreements are typically over-collateralized, U.S. GAAP requires disclosure in this table to limit the reported amount of such collateral to the amount of the related recognized asset or liability for each counterparty. In addition to the amounts included in Table 18.2, we also have balance sheet netting related to derivatives that is disclosed in Note 14 (Derivatives). Table 18.2: Offsetting – Securities and Other Collateralized Financing Activities (in millions) Dec 31, Dec 31, Assets: Resale and securities borrowing agreements Gross amounts recognized $ 114,729 103,140 Gross amounts offset in consolidated balance sheet (1) (24,464) (14,074) Net amounts in consolidated balance sheet (2) 90,265 89,066 Collateral not recognized in consolidated balance sheet (3) (89,592) (88,330) Net amount (4) $ 673 736 Liabilities: Repurchase and securities lending agreements Gross amounts recognized $ 55,054 35,043 Gross amounts offset in consolidated balance sheet (1) (24,464) (14,074) Net amounts in consolidated balance sheet (5) 30,590 20,969 Collateral pledged but not netted in consolidated balance sheet (6) (30,383) (20,820) Net amount (4) $ 207 149 (1) Represents recognized amount of resale and repurchase agreements with counterparties subject to enforceable MRAs that have been offset in our consolidated balance sheet. (2) Includes $68.0 billion and $66.2 billion classified on our consolidated balance sheet in federal funds sold and securities purchased under resale agreements at December 31, 2022 and 2021, respectively. Also includes $22.3 billion and $22.9 billion classified on our consolidated balance sheet in loans at December 31, 2022 and 2021, respectively. (3) Represents the fair value of collateral we have received under enforceable MRAs or MSLAs, limited in the table above to the amount of the recognized asset due from each counterparty. At December 31, 2022 and 2021, we have received total collateral with a fair value of $136.6 billion and $124.4 billion, respectively, all of which we have the right to sell or repledge. These amounts include securities we have sold or repledged to others with a fair value of $59.1 billion and $28.8 billion at December 31, 2022 and 2021, respectively. (4) Represents the amount of our exposure (assets) or obligation (liabilities) that is not collateralized and/or is not subject to an enforceable MRA or MSLA. (5) Amount is classified in short-term borrowings on our consolidated balance sheet. (6) Represents the fair value of collateral we have pledged, related to enforceable MRAs or MSLAs, limited in the table above to the amount of the recognized liability owed to each counterparty. At December 31, 2022 and 2021, we have pledged total collateral with a fair value of $56.3 billion and $35.9 billion, respectively, substantially all of which may be sold or repledged by the counterparty. REPURCHASE AND SECURITIES LENDING AGREEMENTS Securities sold under repurchase agreements and securities lending arrangements are effectively short-term collateralized borrowings. In these transactions, we receive cash in exchange for transferring securities as collateral and recognize an obligation to reacquire the securities for cash at the transaction’s maturity. These types of transactions create risks, including (1) the counterparty may fail to return the securities at maturity, (2) the fair value of the securities transferred may decline below the amount of our obligation to reacquire the securities, and therefore create an obligation for us to pledge additional amounts, and (3) the counterparty may accelerate the maturity on demand, requiring us to reacquire the security prior to contractual maturity. We attempt to mitigate these risks in various ways. Our collateral primarily consists of highly liquid securities. In addition, we underwrite and monitor the financial strength of our counterparties, monitor the fair value of collateral pledged relative to contractually required repurchase amounts, and monitor that our collateral is properly returned through the clearing and settlement process in advance of our cash repayment. Table 18.3 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.

The overnight/continuous repurchase agreements require election of both parties to roll the trade rather than the election to terminate the arrangement as in securities lending.

Segment Reporting [Abstract]
Operating Segments	Note 19: 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 affiliated venture capital and private equity businesses. In addition, Corporate includes all restructuring charges related to our efficiency initiatives. See Note 20 (Revenue and Expenses) for additional information on restructuring charges. 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. 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 low-income 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.

Our revenue is generally recognized either immediately upon the completion of our service or over time as we perform services. Any services performed over time generally require that we render services each period and therefore we measure our progress in completing these services based upon the passage of time. DEPOSIT-RELATED FEES are earned in connection with depository accounts for commercial and consumer customers and include fees for account charges, overdraft services, cash network fees, wire transfer and other remittance fees, and safe deposit box fees. Account charges include fees for periodic account maintenance activities and event-driven services such as stop payment fees. Our obligation for event-driven services is satisfied at the time of the event when the service is delivered, while our obligation for maintenance services is satisfied over the course of each month. Our obligation for overdraft services is satisfied at the time of the overdraft. Cash network fees are earned for processing ATM transactions, and our obligation is completed upon settlement of ATM transactions. Wire transfer and other remittance fees consist of fees earned for providing funds transfer services and issuing cashier’s checks and money orders. Our obligation is satisfied at the time of the performance of the funds transfer service or upon issuance of the cashier’s check or money order. Safe deposit box fees are generally recognized over time as we provide the services. INVESTMENT ADVISORY AND OTHER ASSET-BASED FEES are earned for providing brokerage advisory, asset management and trust services. These fees were impacted by the sales of our Corporate Trust Services business and Wells Fargo Asset Management, which closed in fourth quarter 2021. Fees from advisory account relationships with brokerage customers are charged based on a percentage of the market value of the client’s assets. Services and obligations related to providing investment advice, active management of client assets, and assistance with selecting and engaging a third-party advisory manager are generally satisfied over a month or quarter. Trailing commissions are earned for selling shares to investors and our obligation is satisfied at the time shares are sold. However, these fees are received and recognized over time during the period the customer owns the shares and we remain the broker of record. The amount of trailing commissions is variable based on the length of time the customer holds the shares and on changes in the value of the underlying assets. Asset management services include managing and administering assets, including mutual funds, and institutional separate accounts. Fees for these services are generally determined based on a tiered scale relative to the market value of assets under management (AUM). In addition to AUM, we have client assets under administration (AUA) that earn various administrative fees which are generally based on the extent of the services provided to administer the account. Services with AUM and AUA-based fees are generally satisfied over time. Trust services include acting as a trustee or agent for personal trust and agency assets. Obligations for trust services are generally satisfied over time; however, obligations for activities that are transitional in nature are satisfied at the time of the transaction. COMMISSIONS AND BROKERAGE SERVICES FEES are earned for providing brokerage services. Commissions from transactional accounts with brokerage customers are earned for executing transactions at the client’s direction. Our obligation is generally satisfied upon the execution of the transaction and the fees are based on the size and number of transactions executed. Fees earned from other brokerage services include securities clearance, omnibus and networking fees received from mutual fund companies in return for providing record keeping and other administrative services, and annual account maintenance fees charged to customers. Our obligation is satisfied at the time we provide the service which is generally at the time of the transaction. INVESTMENT BANKING FEES are earned for underwriting debt and equity securities, arranging syndicated loan transactions and performing other advisory services. Our obligation for these services is generally satisfied at closing of the transaction. CARD FEES include credit and debit card interchange and network revenue and various card-related fees. Credit and debit card interchange and network revenue is earned on credit and debit card transactions conducted through payment networks such as Visa, MasterCard, and American Express. Our obligation is satisfied concurrently with the delivery of services on a daily basis. Other card fees represent late fees, cash advance fees, balance transfer fees, and annual fees. Expenses OPERATING LOSSES We may incur expenses related to various loss contingencies, such as customer remediation activities. We establish an accrued liability when a loss event is probable and the amount of the loss can be reasonably estimated. Our operating losses of $7.0 billion, $1.6 billion, and $3.5 billion in 2022, 2021 and 2020, respectively, included expenses primarily related to a variety of historical matters, including litigation, regulatory, and customer remediation matters. See Note 13 (Legal Actions) for additional information on accruals for legal actions. RESTRUCTURING CHARGES The Company began pursuing various initiatives to reduce expenses and create a more efficient and streamlined organization in third quarter 2020. Actions from these initiatives included (i) reorganizing and simplifying business processes and structures to improve internal operations and the customer experience, (ii) reducing headcount, (iii) optimizing third-party spending, including for our technology infrastructure, and (iv) rationalizing our branch and administrative locations, which may include consolidations and closures. Substantially all of the restructuring charges were personnel expenses related to severance costs associated with headcount reductions with payments made over time in accordance with our severance plan as well as payments for other employee benefit costs such as incentive compensation. Restructuring charges are recorded as a component of noninterest expense on our consolidated statement of income. Changes in estimates represent adjustments to noninterest expense based on refinements to previously estimated amounts, which may reflect trends such as higher voluntary employee attrition as well as changes in business activities. Table 20.2 provides details on our restructuring charges. Table 20.2: Accruals for Restructuring Charges Year ended December 31, (in millions) 2022 2021 2020 Balance, beginning of period $ 565 1,214 — Restructuring charges — 726 1,595 Changes in estimates 5 (650) (96) Payments and utilization (404) (725) (285) Balance, end of period $ 166 565 1,214 OTHER EXPENSES Regulatory Charges and Assessments expense, which is included in other noninterest expense, was $860 million, $842 million, and $834 million in 2022, 2021 and 2020, respectively, and primarily consisted of Federal Deposit Insurance Corporation (FDIC) deposit assessment expense.

Retirement Benefits [Abstract]
Employee Benefits	Note 21: Employee Benefits Pension and Postretirement Plans We sponsor a frozen noncontributory qualified defined benefit retirement plan, the Wells Fargo & Company Cash Balance Plan (Cash Balance Plan), which covers eligible employees of Wells Fargo. The Cash Balance Plan was frozen on July 1, 2009, and no new benefits accrue after that date. Prior to July 1, 2009, eligible employees’ Cash Balance Plan accounts were allocated a compensation credit based on a percentage of their certified compensation; the freeze discontinued the allocation of compensation credits after June 30, 2009. Investment credits continue to be allocated to participants’ accounts based on their accumulated balances. We did not make a contribution to our Cash Balance Plan in 2022. We do not expect that we will be required to make a contribution to the Cash Balance Plan in 2023. For the nonqualified pension plans and postretirement benefit plans, there is no minimum required contribution beyond the amount needed to fund benefit payments. We recognize settlement losses for our Cash Balance Plan based on an assessment of whether lump sum benefit payments will, in aggregate for the year, exceed the sum of its annual service and interest cost (threshold). Settlement losses of $221 million and $133 million were recognized during 2022 and 2021, respectively, representing the pro rata portion of the net loss in accumulated other comprehensive income (AOCI) based on the percentage reduction in the Cash Balance Plan’s projected benefit obligation attributable to 2022 and 2021 lump sum payments (included in the “Benefits paid” line in Table 21.1). Additionally, we sponsored the Wells Fargo Canada Corporation Pension Plan to employees in Canada (Canada Pension Plan), a defined benefit retirement plan. In June 2022, an annuity contract was entered into that effected a full settlement of this Canada Pension Plan, resulting in a plan settlement of $29 million and a settlement loss of $5 million. Our nonqualified defined benefit plans are unfunded and provide supplemental defined benefit pension benefits to certain eligible employees. The benefits under these plans were frozen in prior years. Other benefits include health care and life insurance benefits provided to certain retired employees. We reserve the right to amend, modify or terminate any of these benefits at any time. The information set forth in the following tables is based on current actuarial reports using the measurement date of December 31 for our pension and postretirement benefit plans. Table 21.1 presents the changes in the benefit obligation and the fair value of plan assets, the funded status, and the amounts recognized on our consolidated balance sheet. Changes in the benefit obligation for the qualified plans were driven by the amounts of benefits paid and changes in the actuarial loss (gain) amounts, which are driven by changes in the discount rates at December 31, 2022 and 2021, respectively.

In determining the end of year benefit obligation, we assumed an average annual increase of approximately 13.90% for health care costs in 2023. This rate is assumed to trend down 0.60%-1.50% per year until the trend rate reaches an ultimate rate of 4.50% in 2032. The 2022 periodic benefit cost was determined using an initial annual trend rate of 7.50%. This rate was assumed to decrease 0.30%-0.40% per year until the trend rate reached an ultimate rate of 4.50% in 2030. Investment Strategy and Asset Allocation We seek to achieve the expected long-term rate of return with a prudent level of risk, given the benefit obligations of the pension plans and their funded status. Our overall investment strategy is designed to provide our Cash Balance Plan with a moderate amount of long-term growth opportunities while ensuring that risk is mitigated through diversification across numerous asset classes and various investment strategies, coupled with an investment strategy for the fixed income assets that is generally designed to approximate the interest rate sensitivity of the Cash Balance Plan’s benefit obligations. The Cash Balance Plan currently has a target asset allocation mix comprised of the following ranges: 75%-85% fixed income, 10%-20% equities, and 0%-10% in real estate, private equity and other investments. The Employee Benefit Review Committee (EBRC), which includes several members of senior management, formally reviews the investment risk and performance of our Cash Balance Plan on a quarterly basis. Annual Plan liability analysis and periodic asset/liability evaluations are also conducted. Other benefit plan assets include (1) assets held in a 401(h) trust, which are invested with a target mix of 50%-60% equities and 40%-50% fixed income, and (2) assets held in the Retiree Medical Plan Voluntary Employees’ Beneficiary Association (VEBA) trust, which are predominantly invested in fixed income securities and cash. Members of the EBRC formally review the investment risk and performance of these assets on a quarterly basis. Projected Benefit Payments Future benefits that we expect to pay under the pension and other benefit plans are presented in Table 21.7.

VALUATION METHODOLOGIES Following is a description of the valuation methodologies used for assets measured at fair value. Cash and Cash Equivalents – includes investments in collective investment funds valued at fair value based upon the fund’s NAV per share held at year-end. The NAV per share is quoted on a private market that is not active; however, the NAV per share is based on underlying investments traded on an active market. This group of assets also includes investments in registered investment companies valued at the NAV per share held at year-end and in interest-bearing bank accounts. Long Duration, Intermediate (Core), High-Yield, and International Fixed Income – includes investments traded on the secondary markets; prices are measured by using quoted market prices for similar securities, pricing models, and discounted cash flow analyses using significant inputs observable in the market where available, or a combination of multiple valuation techniques. This group of assets also includes highly liquid government securities such as U.S. Treasuries, limited partnerships valued at the NAV, registered investment companies, and collective investment funds described above. Domestic, Global, International and Emerging Market Stocks – investments in exchange-traded equity securities are valued at quoted market values. This group of assets also includes investments in registered investment companies and collective investment funds described above. Real Estate –includes investments in exchange-traded equity securities, registered investment companies, and collective investment funds described above. Hedge Funds / Absolute Return – includes investments in collective investment funds as described above. Other – insurance contracts that are stated at cash surrender value. This group of assets also includes investments in registered investment companies and collective investment funds described above. The methods described above may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. While we believe our valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date. Defined Contribution Retirement Plans We sponsor a qualified defined contribution retirement plan, the Wells Fargo & Company 401(k) Plan (401(k) Plan). Under the 401(k) Plan, after 1 month of service, eligible employees may contribute up to 50% of their certified compensation, subject to statutory limits. Effective January 2021, we implemented the following changes to the 401(k) Plan employer contributions: (1) with some exceptions, employees with one year of service must be employed in a benefit-eligible position on December 15; (2) added a new non-discretionary base contribution of 1% of certified compensation for employees with annual compensation of less than $75,000; (3) replaced the discretionary profit sharing contribution with a discretionary contribution for eligible employees with annual compensation of less than $150,000; and (4) revised the matching contribution vesting and timing. Eligible employees are 100% vested in their base and discretionary contributions after three years of service. A three-year service vesting requirement for matching contributions applies to employees hired after December 31, 2020. Base and matching contributions are made annually at year-end, and the discretionary contribution, if awarded, is made no later than the due date for the Company’s federal income tax return (including extensions) for the plan year. Additionally, we added installment payment options to the existing lump sum and partial lump sum distribution options and added optional advisory services. Prior to January 2021, eligible employees who completed one year of service were eligible to receive the matching contributions quarterly, which are dollar for dollar up to 6% of certified compensation, and a discretionary profit sharing contribution up to 4% of certified compensation, if awarded, paid following the plan year. Matching contributions were 100% vested, and the discretionary profit sharing contributions required three years of vesting service (no change). Total defined contribution retirement plan expenses were $1.0 billion in 2022, and $1.1 billion in both 2021 and 2020.

Deferred taxes related to net unrealized gains (losses) on debt securities, net unrealized gains (losses) on derivatives, foreign currency translation, and employee benefit plan adjustments are recorded in accumulated OCI. See Note 24 (Other Comprehensive Income) for additional information. We have determined that a valuation allowance is required for 2022 in the amount of $232 million, attributable to deferred tax assets in various state and non-U.S. jurisdictions where we believe it is more likely than not that these deferred tax assets will not be realized due to lack of sources of taxable income, limitations on carry back of losses or credits and the inability to implement tax planning to realize these deferred tax assets. We have concluded that it is more likely than not that the remaining deferred tax assets will be realized based on our history of earnings, sources of taxable income in carry back periods, and our ability to implement tax planning strategies. Table 22.4 presents the components of the deferred tax assets related to net operating loss (NOL) and tax credit carry forwards at December 31, 2022. Table 22.4: Deferred Tax Assets Related To Net Operating Loss and Tax Credit Carry Forwards (1) (in millions) Dec 31, U.S. Federal NOLs $ 3,244 U.S. Federal tax credits 1,221 U.S. State NOLs and credits 974 Non-U.S. NOLs and credits 74 Total net operating loss and tax credit carryforwards $ 5,513 (1) U.S. Federal NOLs have no expiration date. The remaining balances, if not utilized, mostly expire in varying amounts through December 31, 2042. We do not intend to distribute earnings of certain non-U.S. subsidiaries in a taxable manner, and therefore intend to limit distributions to non-U.S. earnings previously taxed in the U.S., that would qualify for the 100% dividends received deduction, and that would not result in any significant state or non-U.S. taxes. All other undistributed non-U.S. earnings will continue to be permanently reinvested outside the U.S. and the related tax liability on these earnings is insignificant. Table 22.5 presents the change in unrecognized tax benefits. Table 22.5: Change in Unrecognized Tax Benefits Year ended December 31, (in millions) 2022 2021 Balance, beginning of period $ 5,218 4,826 Additions: For tax positions related to the current year 695 441 For tax positions related to prior years 358 259 Reductions: For tax positions related to prior years (514) (124) Lapse of statute of limitations (13) (164) Settlements with tax authorities (307) (20) Balance, end of period $ 5,437 5,218 Of the $5.4 billion of unrecognized tax benefits at December 31, 2022, approximately $3.6 billion would, if recognized, affect the effective tax rate. The remaining $1.8 billion of unrecognized tax benefits relates to income tax positions on temporary differences. We account for interest and penalties related to income tax liabilities as a component of income tax expense. As of December 31, 2022 and 2021, we have accrued expenses of approximately $436 million and $914 million, respectively, for interest and penalties. In 2022 and 2021, we recognized income tax benefit, net of tax, of $385 million and $33 million, respectively, related to interest and penalties. We are subject to U.S. federal income tax as well as income tax in numerous state and non-U.S. jurisdictions. We are routinely examined by tax authorities in these various jurisdictions. With few exceptions, Wells Fargo and its subsidiaries are not subject to federal, state, local and non-U.S. income tax examinations for taxable years prior to 2011. It is reasonably possible that one or more of the examinations or appeals may be resolved within the next twelve months resulting in a decrease of up to $1.4 billion of our gross unrecognized tax benefits. Table 22.6 summarizes our major tax jurisdiction examination status as of December 31, 2022.

Regulatory Capital Requirements

Regulatory Capital Requirements and Other Restrictions [Abstract]
Regulatory Capital Requirements and Other Restrictions	Note 25: Regulatory Capital Requirements and Other Restrictions Regulatory Capital Requirements The Company and each of its subsidiary banks are subject to regulatory capital adequacy requirements promulgated by federal banking regulators. 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 25.1 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. At December 31, 2022, the Bank and our other insured depository institutions were considered well-capitalized under the requirements of the Federal Deposit Insurance Act. Table 25.1: Regulatory Capital Information Wells Fargo & Company Wells Fargo Bank, N.A.

(1) The SLR consists of Tier 1 capital divided by total leverage exposure. Total leverage exposure consists of total average assets, less goodwill and other permitted Tier 1 capital deductions (net of deferred tax liabilities), plus certain off-balance sheet exposures. (2) The Tier 1 leverage ratio consists of Tier 1 capital divided by total average assets, excluding goodwill and certain other items as determined under the rule. At December 31, 2022, 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%. The G-SIB surcharge is not applicable to the Bank. In addition, the CET1, Tier 1 and total capital ratio requirements for the Company included a stress capital buffer of 3.20% under the Standardized Approach and a capital conservation buffer of 2.50% under the Advanced Approach. The capital ratio requirements for the Bank included a capital conservation buffer of 2.50% under both the Standardized and Advanced Approaches. The Company is required to maintain these risk-based capital ratios and to maintain an SLR of at least 5.00% (composed of a 3.00% minimum requirement plus a supplementary leverage buffer of 2.00%) to avoid restrictions on capital distributions and discretionary bonus payments. The Bank is required to maintain an SLR of at least 6.00% to be considered well-capitalized under applicable regulatory capital adequacy rules. 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. These covered transactions may not exceed 10% of the bank’s capital and surplus (which for this purpose represents Tier 1 and Tier 2 capital, as calculated under the risk-based capital rules, plus the balance of the ACL excluded from Tier 2 capital) with any single nonbank affiliate and 20% of the bank’s capital and surplus with all its nonbank affiliates. Covered transactions that are extensions of credit may require collateral to be pledged to provide added security to the bank. Additionally, federal laws and regulations limit the dividends that a national bank may pay. Dividends that may be paid by a national bank without the express approval of the OCC are generally limited to that bank’s retained net income for the preceding two calendar years plus net income up to the date of any dividend declaration in the current calendar year. Retained net income, as defined by the OCC, consists of net income less dividends declared during the period. Our national bank subsidiaries could have declared additional dividends of $6.4 billion at December 31, 2022, without obtaining prior regulatory approval. We have elected to retain higher capital at our national bank subsidiaries to meet internal capital targets, which are set above regulatory requirements. Our nonbank subsidiaries are also limited by certain federal and state statutory provisions and regulations covering the amount of dividends that may be paid in any given year. In addition, under a Support Agreement dated June 28, 2017, as amended and restated on June 26, 2019, among Wells Fargo & Company, the parent holding company (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, the IHC may be restricted from making dividend payments to the Parent if certain liquidity and/or capital metrics fall below defined triggers or if the Parent’s board of directors authorizes it to file a case under the U.S. Bankruptcy Code. Based on retained earnings at December 31, 2022, our nonbank subsidiaries could have declared additional dividends of $26.9 billion at December 31, 2022, without obtaining prior regulatory approval. Cash Restrictions Cash and cash equivalents may be restricted as to usage or withdrawal. Table 25.2 provides a summary of restrictions on cash and cash equivalents .

Summary of Significant Accounting Policies (Policies)	Dec. 31, 2022
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.
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)); • valuations of residential mortgage servicing rights (MSRs) (Note 6 (Mortgage Banking Activities) and Note 16 (Securitizations and Variable Interest Entities)); • valuations of financial instruments (Note 15 (Fair Values of Assets and Liabilities)); • liabilities for contingent litigation losses (Note 13 (Legal Actions)); • income taxes (Note 22 (Income Taxes)); and • goodwill impairment (Note 7 (Intangible Assets and Other Assets)). Actual results could differ from those estimates.

Consolidation	Consolidation Our consolidated financial statements include the accounts of the Parent and our subsidiaries in which we have a controlling financial interest. When our consolidated subsidiaries follow specialized industry accounting, that accounting is retained in consolidation. We are also a variable interest holder in certain entities in which equity investors do not have the characteristics of a controlling financial interest or where the entity does not have enough equity at risk to finance its activities without additional subordinated financial support from other parties (collectively referred to as variable interest entities (VIEs)). Our variable interest arises from contractual, ownership or other monetary interests in the entity, which change with fluctuations in the fair value of the entity’s net assets. We consolidate a VIE if we are the primary beneficiary, which is when we have both the power to direct the activities that most significantly impact the VIE and a variable interest that could potentially be significant to the VIE. To determine whether or not a variable interest we hold could potentially be significant to the VIE, we consider both qualitative and quantitative factors regarding the nature, size and form of our involvement with the VIE. We assess whether or not we are the primary beneficiary of a VIE on an ongoing basis. Significant intercompany accounts and transactions are eliminated in consolidation. When we have significant influence over operating and financing decisions for a company but do not own a majority of the voting equity interests, we account for the investment using the equity method of accounting, which requires us to recognize our proportionate share of the company’s earnings. If we do not have significant influence, we account for the equity security under the fair value method, cost meth od or measurement alternative. Noncontrolling interests represent the portion of net income and equity attributable to third-party owners of consolidated subsidiaries that are not wholly-owned by Wells Fargo. Substantially all of our noncontrolling interests relate to our affiliated venture capital and private equity businesses.
Cash, Cash Equivalents, and Restricted Cash	Cash, Cash Equivalents, and Restricted Cash Cash, cash equivalents and restricted cash are recorded at amortized cost and include cash on hand, cash items in transit, and amounts due from or held with other depository institutions. See Note 25 (Regulatory Capital Requirements and Other Restrictions) for additional information on the restrictions on cash and cash equivalents.
Securities and other Collateralized Financing Agreements	Securities and Other Collateralized Financing Agreements Resale and repurchase agreements, as well as securities borrowing and lending agreements, are accounted for as collateralized financing transactions and are recorded at the acquisition or sale price plus accrued interest. We monitor the fair value of securities or other assets purchased and sold as well as the collateral pledged and received. Additional collateral is pledged or returned to maintain the appropriate collateral position for the transactions. These financing transactions do not create material credit risk given the collateral provided and the related monitoring process. We include securities purchased under securities financing agreements in federal funds sold and securities purchased under resale agreements on our consolidated balance sheet. We include collateral other than securities purchased under resale agreements in Loans on our consolidated balance sheet. We include securities sold under securities financing agreements in short-term borrowings on our consolidated balance sheet. At December 31, 2022 and 2021, short-term borrowings were primarily comprised of federal funds purchased and securities sold under agreements to repurchase. Assets and liabilities arising from securities and other collateralized financing transactions with a single counterparty are presented net on the balance sheet provided they meet certain criteria that permit balance sheet netting. See Note 18 (Pledged Assets and Collateral) for additional information on our offsetting policy.
Loans Held for Sale	Loans Held for Sale Loans held for sale (LHFS) generally includes commercial and residential mortgage loans originated or purchased for sale in the securitization or whole loan market. We have elected the fair value option for a majority of residential LHFS (see Note 15 (Fair Values of Assets and Liabilities)). The remaining residential LHFS are held at the lower of cost or fair value (LOCOM) and are measured on a pool level basis. Commercial LHFS are generally held at LOCOM and are measured on an individual loan basis. We have elected the fair value option for certain commercial loans included in LHFS that are used in market-making activities for our trading business. Gains and losses on residential and commercial mortgage LHFS are generally recorded in mortgage banking noninterest income. Gains and losses on trading LHFS are recognized in net gains from trading activities. Gains and losses on other LHFS are recognized in other noninterest income. Direct loan origination costs and fees for LHFS under the fair value option are recognized in earnings at origination. For LHFS recorded at LOCOM, direct loan origination costs and fees are deferred at origination and are recognized in earnings at time of sale. Interest income on LHFS is calculated based upon the note rate of the loan and is recorded in interest income. Commitments to originate mortgage LHFS are accounted for as derivatives and are measured at fair value. When a determination is made at the time of commitment to originate loans as held for investment, it is our intent to hold these loans to maturity or for the foreseeable future, subject to periodic review under our management evaluation processes, including corporate asset/liability management. If subsequent changes occur, including changes in interest rates, our business strategy, or other market conditions, we may change our intent to hold these loans. When management makes this determination, we immediately transfer these loans to the LHFS portfolio at LOCOM.
Loans	Loans 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. Unearned income, deferred fees and costs, and discounts and premiums are amortized to interest income generally over the contractual life of the loan using the effective interest method. Loan commitment fees collected at closing are deferred and amortized to noninterest income on a straight-line basis over the commitment period if loan funding is unlikely. Upon funding, deferred loan commitment fees are amortized to interest income over the contractual life of the loan. Loans also include financing leases where we are the lessor (see the “Leasing Activity” section in this Note for our accounting policy for leases) and resale agreements involving collateral other than securities (see “Securities and Other Collateralized Financing Agreements” section in this Note for our accounting policy for other collateralized financing agreements). See Note 5 (Loans and Related Allowance for Credit Losses) for additional information regarding our accounting for loans. NONACCRUAL AND PAST DUE LOANS We generally place loans on nonaccrual status when: • the full and timely collection of interest or principal becomes uncertain (generally based on an assessment of the borrower’s financial condition and the adequacy of collateral, if any), such as in bankruptcy or other circumstances; • they are 90 days (120 days with respect to residential mortgage loans) past due for interest or principal, unless the loan is both well-secured and in the process of collection; • part of the principal balance has been charged off; or • for junior lien mortgage loans, we have evidence that the related first lien mortgage may be 120 days past due or in the process of foreclosure regardless of the junior lien delinquency status. Credit card loans are not placed on nonaccrual status, but are generally fully charged off when the loan reaches 180 days past due. When we place a loan on nonaccrual status, we reverse the accrued unpaid interest receivable against interest income and suspend amortization of any net deferred fees. If the ultimate collectability of the recorded loan balance is in doubt on a nonaccrual loan, the cost recovery method is used and cash collected is applied to first reduce the carrying value of the loan to zero and then as a recovery of prior charge-offs. Otherwise, interest income may be recognized to the extent cash is received. Generally, we return a loan to accrual status when all delinquent interest and principal become current under the terms of the loan agreement and collectability of remaining principal and interest is no longer doubtful. We may re-underwrite modified loans at the time of a restructuring to determine if there is sufficient evidence of sustained repayment capacity based on the borrower’s financial strength, including documented income, debt to income ratios and other factors. If the borrower has demonstrated performance under the previous terms and the underwriting process shows the capacity to continue to perform under the restructured terms, the loan will generally remain in accruing status. When a loan classified as a troubled debt restructuring (TDR) performs in accordance with its modified terms, the loan either continues to accrue interest (for performing loans) or will return to accrual status after the borrower demonstrates a sustained period of performance (generally six consecutive months of payments, or equivalent, inclusive of consecutive payments made prior to the modification). Loans will be placed on nonaccrual status and a corresponding charge-off is recorded if the re-underwriting did not include an evaluation of the borrower’s ability to repay or we believe it is probable that principal and interest contractually due under the modified terms of the agreement will not be collectible. Our loans are considered past due when contractually required principal or interest payments have not been made on the due dates. LOAN CHARGE-OFF POLICIES For commercial loans, we generally fully charge off or charge down to net realizable value (fair value of collateral, less estimated costs to sell) for loans secured by collateral when: • management judges the loan to be uncollectible; • repayment is deemed to be protracted beyond reasonable time frames; • the loan has been classified as a loss by either our internal loan review process or our banking regulatory agencies; • the customer has filed bankruptcy and the loss becomes evident owing to a lack of assets; • the loan is 180 days past due unless both well-secured and in the process of collection; or • the loan is probable of foreclosure, and we have received an appraisal of less than the recorded loan balance. For consumer loans, we fully charge off or charge down to net realizable value when deemed uncollectible due to bankruptcy or other factors, or no later than reaching a defined number of days past due, as follows: • Residential mortgage loans – We generally charge down to net realizable value when the loan is 180 days past due and fully charge-off when the loan exceeds extended delinquency dates. • Auto loans – We generally fully charge off when the loan is 120 days past due. • Credit card loans – We generally fully charge off when the loan is 180 days past due. • Unsecured loans – We generally fully charge off when the loan is 120 days past due. • Unsecured lines – We generally fully charge off when the loan is 180 days past due. • Other secured loans – We generally fully or partially charge down to net realizable value when the loan is 120 days past due. TROUBLED DEBT RESTRUCTURINGS In situations where, for economic or legal reasons related to a borrower’s financial difficulties, we grant a concession for other than an insignificant period of time to the borrower that we would not otherwise consider, the related loan is classified as a troubled debt restructuring (TDR). These modified terms may include interest rate reductions, principal forgiveness, term extensions, payment forbearance and other actions intended to minimize our economic loss and to avoid foreclosure or repossession of the collateral, if applicable. For modifications where we forgive principal, the entire amount of such principal forgiveness is immediately charged off. If the underwriting for a TDR modification did not include an evaluation of the borrower’s ability to repay, the loan is deemed collateral dependent. Other than resolutions such as foreclosures, sales and transfers to held-for-sale, we may remove loans held for investment from TDR classification, but only if they have been refinanced or restructured at market terms and qualify as a new loan. TROUBLED DEBT RESTRUCTURINGS AND OTHER RELIEF RELATED TO COVID-19 The Coronavirus, Aid, Relief, and Economic Security Act (the CARES Act) and the Interagency Statement on Loan Modifications and Reporting for Financial Institutions Working with Customers Affected by the Coronavirus (Revised) issued by federal regulators in April 2020 (the Interagency Statement) provide optional, temporary relief from accounting for certain loan modifications as TDRs. Based on guidance in the CARES Act and Interagency Statement, modifications related to the adverse effects of Coronavirus Disease 2019 (COVID-19) that meet certain criteria are exempt from TDR classification. We ceased applying TDR relief provided by the CARES Act upon the expiration of the CARES Act on January 1, 2022. During 2022, we continued to apply the TDR relief provided by the Interagency Statement for eligible COVID-related residential mortgage loan modifications. For COVID-19-related modifications in the form of payment deferrals or payment forbearance, delinquency status will not advance and loans that were accruing at the time the relief is provided will generally not be placed on nonaccrual status during the deferral period. Interest accrued during payment deferrals or payment forbearance may be included in the principal balance of the loans and charge-offs will generally be based on delinquency status after the loan exits the deferral or forbearance period. Loans that exit COVID-related deferrals or payment forbearance are placed on nonaccrual status if there is no evidence that the borrower can resume making payments or if the borrower requests additional modifications. FORECLOSED ASSETS Foreclosed assets obtained through our lending activities primarily include real estate. Generally, loans have been written down to their net realizable value prior to foreclosure. Any further reduction to their net realizable value is recorded with a charge to the ACL at foreclosure. We allow up to 90 days after foreclosure to finalize determination of net realizable value. Thereafter, changes in net realizable value are recorded to noninterest expense. The net realizable value of these assets is reviewed and updated periodically depending on the type of property. Certain government-guaranteed mortgage loans upon foreclosure are included in accounts receivable, not foreclosed assets. These receivables were loans insured by the
Allowance for Credit Losses	Allowance for Credit Losses The ACL is management’s estimate of the current expected life-time credit losses in the loan portfolio and unfunded credit commitments, at the balance sheet date, excluding loans and unfunded credit commitments carried at fair value or held for sale. Additionally, we maintain an ACL for AFS and HTM debt securities, other financing receivables measured at amortized cost, and other off-balance sheet credit exposures. While we attribute portions of the allowance to specific financial asset classes (loan and debt security portfolios), loan portfolio segments (commercial and consumer) or major security type, the entire ACL is available to absorb credit losses of the Company. Our ACL process involves procedures to appropriately consider the unique risk characteristics of our financial asset classes, portfolio segments, and major security types. For each loan portfolio segment and each major HTM debt security type, losses are estimated collectively for groups of loans or securities with similar risk characteristics. For loans and securities that do not share similar risk characteristics with other financial assets, the losses are estimated individually, which generally includes our nonperforming large commercial loans and non-accruing HTM debt securities. For AFS debt securities, losses are estimated at the individual security level. Our ACL amounts are influenced by a variety of factors, including changes in loan and debt security volumes, portfolio credit quality, and general economic conditions. General economic conditions are forecasted using economic variables which will create volatility as those variables change over time. See Table 1.1 for key economic variables used for our loan portfolios. Table 1.1: Key Economic Variables Loan Portfolio Key economic variables Total commercial • Gross domestic product • Commercial real estate asset prices, where applicable • Unemployment rate Residential mortgage • Home price index • Unemployment rate Other consumer (including credit card, auto, and other consumer) • Unemployment rate Our approach for estimating expected life-time credit losses for loans and debt securities includes the following key components: • An initial loss forecast period of two years for all portfolio segments and classes of financing receivables and off-balance-sheet credit exposures. This period reflects management’s expectation of losses based on forward-looking economic scenarios over that time. We forecast multiple economic scenarios that generally include a base scenario with an optimistic (upside) and one or more pessimistic (downside) scenarios, which are weighted by management to estimate future credit losses. • Long-term average loss expectations estimated by reverting to the long-term average, on a linear basis, for each of the economic variables forecasted during the initial loss forecast period. These long-term averages are based on observations over multiple economic cycles. The reversion period, which may be up to two years, is assessed on a quarterly basis. • The remaining contractual term of a loan is adjusted for expected prepayments and certain expected extensions, renewals, or modifications. We extend the contractual term when we are not able to unconditionally cancel contractual renewals or extension options. We also incorporate any scenarios where we reasonably expect to provide an extension through a TDR. Credit card loans have indeterminate maturities, which requires that we determine a contractual life by estimating the application of future payments to the outstanding loan amount. • Utilization of discounted cash flow (DCF) methods to measure credit impairment for loans modified in a troubled debt restructuring, unless they are collateral dependent and measured at the fair value of the collateral. The DCF methods obtain estimated life-time credit losses using the initial and historical mean loss forecast periods described above. • For AFS debt securities and certain beneficial interests classified as HTM, we utilize DCF methods to measure the ACL, which incorporate expected credit losses using the conceptual components described above. For most HTM debt securities, the ACL is measured using an expected loss model, similar to the methodology used for loans. The ACL for financial assets held at amortized cost is a valuation account that is deducted from, or added to, the amortized cost basis of the financial assets to present the net amount expected to be collected. When credit expectations change, the valuation account is adjusted with changes reported in provision for credit losses. If amounts previously charged off are subsequently expected to be collected, we may recognize a negative allowance, which is limited to the amount that was previously charged off. F or financial assets with an ACL estimated using DCF methods, changes in the ACL due to the passage of time are recorded in interest income. The ACL for AFS debt securities reflects the amount of unrealized loss related to expected credit losses, limited by the amount that fair value is less than the amortized cost basis (fair value floor) and cannot have an associated negative allowance. For certain financial assets, such as residential real estate loans guaranteed by the Government National Mortgage Association (GNMA), an agency of the federal government, U. S. Treasury and Agency mortgage-backed debt securities and certain sovereign debt securities, the Company has not recognized an ACL as our expectation of loss is zero, based on historical losses and consideration of current and forecasted conditions. For financial assets that are collateral-dependent, we will measure the ACL based on the fair value of the collateral. If we intend to sell the underlying collateral, we will measure the ACL based on the collateral’s net realizable value. In most situations, based on our charge-off policies, we will immediately write-down the financial asset to the fair value of the collateral or net realizable value. For consumer loans, collateral-dependent financial assets may have collateral in the form of residential real estate, autos or other personal assets. For commercial loans, collateral-dependent financial assets may have collateral in the form of commercial real estate or other business assets. We do not generally record an ACL for accrued interest receivables because uncollectible accrued interest is reversed through interest income in a timely manner in line with our non-accrual and past due policies for loans and debt securities. For consumer credit card and certain consumer lines of credit, we include an ACL for accrued interest and fees since these loans are neither placed on nonaccrual status nor written off until the loan is 180 days past due. Accrued interest receivables are included in other assets, except for certain revolving loans, such as credit card loans. COMMERCIAL LOAN PORTFOLIO SEGMENT ACL METHODOLOGY Generally, commercial loans, which include net investments in lease financing, are assessed for estimated losses by grading each loan using various risk factors as identified through periodic reviews. Our estimation approach for the commercial portfolio reflects the estimated probability of default in accordance with the borrower’s financial strength and the severity of loss in the event of default, considering the quality of any underlying collateral. Probability of default, loss severity at the time of default, and exposure at default are statistically derived through historical observations of default and losses after default within each credit risk rating. These estimates are adjusted as appropriate for risks identified from current and forecasted economic conditions and credit quality trends. Unfunded credit commitments are evaluated based on a conversion factor to derive a funded loan equivalent amount. The estimated probability of default and loss severity at the time of default are applied to the funded loan equivalent amount to estimate losses for unfunded credit commitments. CONSUMER LOAN PORTFOLIO SEGMENT ACL METHODOLOGY For consumer loans, we determine the allowance using a pooled approach based on the individual risk characteristics of the loans within those pools. Quantitative modeling methodologies that estimate probability of default, loss severity at the time of default and exposure at default are typically leveraged to estimate expected loss. These methodologies pool loans, generally by product types with similar risk characteristics, such as residential real estate mortgages, auto loans and credit cards. As appropriate and to achieve greater accuracy, we may further stratify selected portfolios by sub-product, risk pool, loss type, geographic location and other predictive characteristics. We use attributes such as delinquency status, Fair Isaac Corporation (FICO) scores, and loan-to-value ratios (where applicable) in the development of our consumer loan models, in addition to home price trends, unemployment trends, and other economic variables that may influence the frequency and severity of losses in the consumer portfolio. OTHER QUALITATIVE FACTORS The ACL includes amounts for qualitative factors which may not be adequately reflected in our loss models. These amounts represent management’s judgment of risks in the processes and assumptions used in establishing the ACL. Generally, these amounts are established at a granular level below our loan portfolio segments. We also consider economic environmental factors, modeling assumptions and performance, process risk, and other subjective factors, including industry trends and emerging risk assessments. OFF-BALANCE SHEET CREDIT EXPOSURES Our off-balance sheet credit exposures include unfunded loan commitments (generally in the form of revolving lines of credit), financial guarantees not accounted for as insurance contracts or derivatives, including standby letters of credit, and other similar instruments. For off-balance sheet credit exposures, we recognize an ACL associated with the unfunded amounts. We do not recognize an ACL for commitments that are unconditionally cancelable at our discretion. Additionally, we recognize an ACL for financial guarantees that create off-balance sheet credit exposure, such as loans sold with credit recourse and factoring guarantees. ACL for off-balance sheet credit exposures are reported as a liability in accrued expenses and other liabilities on our consolidated balance sheet. OTHER FINANCIAL ASSETS Other financial assets are evaluated for expected credit losses. These other financial assets include accounts receivable for fees, receivables from government-sponsored entities, such as Federal National Mortgage Association (FNMA) and Federal Home Loan Mortgage Corporation (FHLMC), and GNMA, and other accounts receivables from high-credit quality counterparties, such as central clearing counterparties. Many of these financial assets are generally not expected to have an ACL as there is a zero loss expectation (e.g., government guarantee) based on no historical credit losses and consideration of current and forecasted conditions. Some financial assets, such as loans to employees, maintain an ACL that is presented on a net basis with the related amortized cost amounts in other assets on our consolidated balance sheet. A provision for credit losses is not recognized separately from the regular income or expense associated with these financial assets. Securities purchased under resale agreements are generally over-collateralized by securities or cash and are generally short-term in nature. We have elected the practical expedient for these financial assets given collateral maintenance provisions. These provisions require that we monitor the collateral value and customers are required to replenish collateral, if needed. Accordingly, we generally do not maintain an ACL for these financial assets.
Purchased Credit Deteriorated Financial Assets	Purchased Credit Deteriorated Financial Assets Financial assets acquired that are of poor credit quality and with more than an insignificant evidence of credit deterioration since their origination or issuance are purchased credit deteriorated (PCD) assets. PCD assets include HTM and AFS debt securities and loans. PCD assets are recorded at their purchase price plus an ACL estimated at the time of acquisition. Under this approach, there is no provision for credit losses recognized at acquisition; rather, there is a gross-up of the purchase price of the financial asset for the estimate of expected credit losses and a corresponding ACL recorded. Changes in estimates of expected credit losses after acquisition are recognized as provision for credit losses in subsequent periods. In general, interest income recognition for PCD financial assets is consistent with interest income recognition for the similar non-PCD financial asset.
Leasing Activity, As Lessor	Leasing Activity AS LESSOR We lease equipment to our customers under financing or operating leases. Financing leases, which includes both direct financing and sales-type leases, are presented in loans and are recorded at the discounted amounts of lease payments receivable plus the estimated residual value of the leased asset. Leveraged leases, which are a form of financing leases, are reduced by related non-recourse debt from third-party investors. Lease payments receivable reflect contractual lease payments adjusted for renewal or termination options that we believe the customer is reasonably certain to exercise. The residual value reflects our best estimate of the expected sales price for the equipment at lease termination based on sales history adjusted for recent trends in the expected exit markets. Many of our leases allow the customer to extend the lease at prevailing market terms or purchase the asset for fair value at lease termination. Our allowance for loan losses for financing leases considers both the collectability of the lease payments receivable as well as the estimated residual value of the leased asset. We typically purchase residual value insurance on our financing leases to reduce the risk of loss at lease termination. In connection with a lease, we m ay finance the customer’s purchase of other products or services from the equipment vendor and allocate the contract consideration between the use of the asset and the purchase of those products or services. Amounts allocated are reported in loans as commercial and industrial loans, rather than as lease financing. Our primary income from financing leases is interest income recognized using the effective interest method. Variable lease revenue, such as reimbursement for property taxes, are included in lease income within noninterest income. Operating lease assets are presented in other assets, net of accumulated depreciation. Periodic depreciation expense is recorded on a straight-line basis over the estimated useful life of the leased asset and are included in other noninterest expense. Operating lease assets are reviewed periodically for impairment and an impairment loss is recognized if the carrying amount of operating lease assets exceeds fair value and is not recoverable. Recoverability is evaluated by comparing the carrying amount of the leased assets to undiscounted cash flows expected through the operation or sale of the asset. Impairment charges for operating lease assets are included in other noninterest income. Operating lease rental income for leased assets is recognized in lease income within noninterest income on a straight-line basis over the lease term. Variable revenue on operating leases include reimbursements of costs, including property taxes, which fluctuate over time, as well as rental revenue based on usage. For leases of railcars, revenue for maintenance services provided under the lease is recognized in lease income. We elected to exclude from revenue and expenses any sales tax incurred on lease payments which are reimbursed by the lessee. Substantially all of our leased assets are protected against casualty loss through third-party insurance.
Leasing Activity, As Lessee	AS LESSEE We enter into lease agreements to obtain the right to use assets for our business operations, substantially all of which are real estate. Lease liabilities and right-of-use (ROU) assets are recognized when we enter into operating or financing leases and represent our obligations and rights to use these assets over the period of the leases and may be re-measured for certain modifications. Operating lease liabilities include fixed and in-substance fixed payments for the contractual duration of the lease, adjusted for renewals or terminations which were considered probable of exercise when measured. The lease payments are discounted using a rate that approximates a collateralized borrowing rate for the estimated duration of the lease as the implicit discount rate is typically not known. The discount rate is updated when re-measurement events occur. The related operating lease ROU assets may differ from operating lease liabilities due to initial direct costs, deferred or prepaid lease payments and lease incentives. We present operating lease liabilities in accrued expenses and other liabilities and the related operating lease ROU assets in other assets. The amortization of operating lease ROU assets and the accretion of operating lease liabilities are reported together as fixed lease expense and are included in occupancy expense within noninterest expense. The fixed lease expense is recognized on a straight-line basis over the life of the lease. Some operating leases include variable lease payments and are recognized as incurred in net occupancy expense within noninterest expense. For substantially all of our leased assets, we account for consideration paid under the contract for maintenance or other services as lease payments. We exclude certain asset classes, with original terms of less than one year from the operating lease ROU assets and lease liabilities. The related short-term lease expense is included in net occupancy expense. Finance lease liabilities are presented in long-term debt and the associated finance ROU assets are presented in premises and equipment. See Note 8 (Leasing Activity) for additional information.
Deposits, Short-term Borrowings and Long-term Debt	Deposits, Short-term Borrowings and Long-term Debt Customer deposits, short-term borrowings, and long-term debt are recorded at amortized cost, unless we have elected the fair value option for these items. For example, we may elect the fair value option for certain structured notes. We generally report borrowings with original maturities of one year or less as short-term borrowings and borrowings with original maturities of greater than one year as long-term debt on our consolidated balance sheet. We do not reclassify long-term debt to short-term borrowings within a year of maturity. Refer to Note 9 (Deposits) for further information on deposits, Note 10 (Long-Term Debt) for further information on long-term debt, and Note 15 (Fair Values of Assets and Liabilities) for additional information on fair value, including fair value option elections.
Securitizations and Beneficial Interests	Securitizations and Beneficial Interests Securitizations are transactions in which financial assets are sold to a Special Purpose Entity (SPE), which then issues beneficial interests collateralized by the transferred financial assets. Beneficial interests are generally issued in the form of senior and subordinated interests, and in some cases, we may obtain beneficial interests issued by the SPE. Additionally, from time to time, we may re-securitize certain financial assets in a new securitization transaction. See Note 16 (Securitizations and Variable Interest Entities) for additional information about our involvement with SPEs. The assets and liabilities transferred to a SPE are excluded from our consolidated balance sheet if the transfer qualifies as a sale and we are not required to consolidate the SPE. For transfers of financial assets recorded as sales, we recognize and initially measure at fair value all assets obtained (including beneficial interests or mortgage servicing rights) and all liabilities incurred. We record a gain or loss in noninterest income for the difference between assets obtained (net of liabilities incurred) and the carrying amount of the assets sold. Beneficial interests obtained from, and liabilities incurred in, securitizations with off-balance sheet entities may include debt and equity securities, loans, MSRs, derivative assets and liabilities, other assets, and other obligations such as liabilities for mortgage repurchase losses or long-term debt and are accounted for as described within this Note.
Mortgage Servicing Rights	Mortgage Servicing Rights We recognize MSRs resulting from a sale or securitization of mortgage loans that we originate (asset transfers) or through a direct purchase of such rights. We initially record all of our MSRs at fair value. Subsequently, residential loan MSRs are carried at fair value. Commercial MSRs are subsequently measured at LOCOM. The valuation and sensitivity of MSRs is discussed further in Note 6 (Mortgage Banking Activities), Note 15 (Fair Values of Assets and Liabilities) and Note 16 (Securitizations and Variable Interest Entities). For MSRs carried at fair value, changes in fair value are reported in mortgage banking noninterest income in the period in which the change occurs. MSRs subsequently measured at LOCOM are amortized in proportion to, and over the period of, estimated net servicing income. The amortization of MSRs is reported in mortgage banking noninterest income, analyzed monthly and adjusted to reflect changes in prepayment rates, as well as other factors. MSRs accounted for at LOCOM are periodically evaluated for impairment based on the fair value of those assets. For purposes of impairment evaluation and measurement, we stratify MSRs based on the predominant risk characteristics of the underlying loans, including investor and product type. If, by individual stratum, the carrying amount of these MSRs exceeds fair value, a valuation allowance is established. The valuation allowance is adjusted as the fair value changes.
Premises and Equipment	Premises and EquipmentPremises and equipment are carried at cost less accumulated depreciation and amortization. We use the straight-line method of depreciation and amortization. Depreciation and amortization expense for premises and equipment was $1.2 billion in 2022 and $1.4 billion in both 2021 and 2020. Estimated useful lives range up to 40 years for buildings and improvements, up to 10 years for furniture and equipment, and the shorter of the estimated useful life (up to 8 years) or the lease term for leasehold improvements.
Goodwill and Identifiable Intangible Assets	Goodwill and Identifiable Intangible Assets Goodwill is recorded for business combinations when the purchase price is higher than the fair value of the acquired net assets, including identifiable intangible assets. We assess goodwill for impairment at a reporting unit level on an annual basis or more frequently in certain circumstances. We have determined that our rep orting units are at the reportable operating segment level or one level below. We identify the reporting units based on how the segments and reporting units are managed, taking into consideration the economic characteristics, nature of the products and services, and customers of the segments and reporting units. We allocate goodwill to applicable reporting units based on their relative fair value at the time we acquire a business and when we have a significant business reorganization. If we sell a business, a portion of goodwill is included with the carrying amount of the divested business. We have the option of performing a qualitative assessment of goodwill. We may also elect to bypass the qualitative test and proceed directly to a quantitative test. If we perform a qualitative assessment of goodwill to test for impairment and conclude it is more likely than not that a reporting unit’s fair value is greater than its carrying amount, quantitative tests are not required. However, if we determine it is more likely than not that a reporting unit’s fair value is less than its carrying amount, we complete a quantitative assessment to determine if there is goodwill impairment. We apply various quantitative valuation methodologies, including discounted cash flow and earnings multiple approaches, to determine the estimated fair value, which is compared with the carrying value of each reporting unit. A goodwill impairment loss is recognized if the fair value is less than the carrying amount, including goodwill. The goodwill impairment loss is limited to the amount of goodwill allocated to the reporting unit. We recognize impairment losses as a charge to other noninterest expense and a reduction to the carrying value of goodwill. Subsequent reversals of goodwill impairment are prohibited. We amortize customer relationship intangible assets on an accelerated basis over useful lives not exceeding 10 years. We review intangible assets for impairment whenever events or changes in circumstances indicate that their carrying amounts may not be recoverable. Impairment is indicated if the sum of undiscounted estimated future net cash flows is less than the carrying value of the asset. Impairment is permanently recognized by writing down the asset to the extent that the carrying value exceeds the estimated fair value.
Derivatives and Hedging Activities	Derivatives and Hedging Activities DERIVATIVES We recognize all derivatives on our consolidated balance sheet at fair value. On the date we enter into a derivative contract, we categorize the derivative as either an accounting hedge, economic hedge or part of our customer accommodation trading and other portfolio. Accounting hedges are either fair value or cash flow hedges. Fair value hedges represent the hedge of the fair value of a recognized asset or liability or an unrecognized firm commitment, including hedges of foreign currency exposure. Cash flow hedges represent the hedge of a forecasted transaction or the variability of cash flows to be paid or received related to a recognized asset or liability. Economic hedges and customer accommodation trading and other derivatives do not qualify for, or we have elected not to apply, hedge accounting. Economic hedges are derivatives we use to manage interest rate, foreign currency and certain other risks associated with our non-trading activities. Customer accommodation trading and other derivatives predominantly represents derivatives related to our trading business activities. We report changes in the fair values of these derivatives in noninterest income or noninterest expense. FAIR VALUE HEDGES We record changes in the fair value of the derivative in income, except for certain derivatives in which a portion is recorded to OCI. We record basis adjustments to the amortized cost of the hedged asset or liability due to the changes in fair value related to the hedged risk with the offset recorded in earnings. We present derivative gains or losses in the same income statement category as the hedged asset or liability, as follows: • For fair value hedges of interest rate risk, amounts are reflected in net interest income; • For hedges of foreign currency risk, amounts representing the fair value changes less the accrual for periodic cash flow settlements are reflected in noninterest income. The periodic cash flow settlements are reflected in net interest income; • For hedges of both interest rate risk and foreign currency risk, amounts representing the fair value change less the accrual for periodic cash flow settlements is attributed to both net interest income and noninterest income. The periodic cash flow settlements are reflected in net interest income. The entire derivative gain or loss is included in the assessment of hedge effectiveness for all fair value hedge relationships, except for hedges of foreign-currency denominated AFS debt securities and long-term debt liabilities hedged with cross-currency swaps. The change in fair value of these swaps attributable to cross-currency basis spread changes is excluded from the assessment of hedge effectiveness. The initial fair value of the excluded component is amortized to net interest income and the difference between changes in fair value of the excluded component and the amount recorded in earnings is recorded in OCI. CASH FLOW HEDGES We record changes in the fair value of the derivative in OCI. We subsequently reclassify gains and losses from these changes in fair value from OCI to earnings in the same period(s) that the hedged transaction affects earnings and in the same income statement category as the hedged item. The entire gain or loss on these derivatives is included in the assessment of hedge effectiveness. DOCUMENTATION AND EFFECTIVENESS ASSESSMENT FOR ACCOUNTING HEDGES For fair value and cash flow hedges qualifying for hedge accounting, we formally document at inception the relationship between hedging instruments and hedged items, our risk management objective, strategy and our evaluation of effectiveness for our hedge transactions. This process includes linking all derivatives designated as fair value or cash flow hedges to specific assets and liabilities on our consolidated balance sheet or to specific forecasted transactions. We assess hedge effectiveness using regression analysis, both at inception of the hedging relationship and on an ongoing basis. For fair value hedges, the regression analysis involves regressing the periodic change in fair value of the hedging instrument against the periodic changes in fair value of the asset or liability being hedged due to changes in the hedged risk(s). For cash flow hedges, the regression analysis involves regressing the periodic changes in fair value of the hedging instrument against the periodic changes in fair value of a hypothetical derivative. The hypothetical derivative has terms that identically match and offset the cash flows of the forecasted transaction being hedged due to changes in the hedged risk(s). The initial assessment for fair value and cash flow hedges includes an evaluation of the quantitative measures of the regression results used to validate the conclusion of high effectiveness. Periodically, as required, we also formally assess whether the derivative we designated in each hedging relationship is expected to be and has been highly effective in offsetting changes in fair values or cash flows of the hedged item using the regression analysis method. DISCONTINUING HEDGE ACCOUNTING We discontinue hedge accounting prospectively when (1) a derivative is no longer highly effective in offsetting changes in the fair value or cash flows of a hedged item, (2) a derivative expires or is sold, terminated or exercised, (3) we elect to discontinue hedge accounting, or (4) when the forecasted transaction is no longer probable of occurring in a cash flow hedge. When we discontinue fair value hedge accounting, we no longer adjust the previously hedged asset or liability for changes in fair value. The remaining cumulative adjustments to the hedged item and accumulated amounts reported in OCI are accounted for in the same manner as other components of the carrying amount of the asset or liability. For example, for financial debt instruments such as AFS debt securities, loans or long-term debt, these amounts are amortized into net interest income over the remaining life of the asset or liability similar to other amortized cost basis adjustments. If the hedged item is derecognized, the accumulated amounts reported in OCI are immediately reclassified to net interest income. If the derivative continues to be held after fair value hedge accounting ceases, we carry the derivative on the consolidated balance sheet at its fair value with changes in fair value included in noninterest income. When we discontinue cash flow hedge accounting and it is probable that the forecasted transaction will occur, the accumulated amount reported in OCI at the de-designation date continues to be reported in OCI until the forecasted transaction affects earnings at which point the related OCI amount is reclassified to net interest income. If cash flow hedge accounting is discontinued and it is probable the forecasted transaction will no longer occur, the accumulated gains and losses reported in OCI at the de-designation date is immediately reclassified to noninterest income. If the derivative continues to be held after cash flow hedge accounting ceases, we carry the derivative on our consolidated balance sheet at its fair value with changes in fair value included in noninterest income. EMBEDDED DERIVATIVES We may purchase or originate financial instruments that contain an embedded derivative. At inception of the financial instrument, we assess (1) if the economic characteristics of the embedded derivative are not clearly and closely related to the economic characteristics of the host contract, (2) if the financial instrument that embodies both the embedded derivative and the host contract is not measured at fair value with changes in fair value reported in earnings, and (3) if a separate instrument with the same terms as the embedded instrument would meet the definition of a derivative. If the embedded derivative meets all of these conditions, we separate it from the hybrid contract by recording the bifurcated derivative at fair value and the remaining host contract at the difference between the basis of the hybrid instrument and the fair value of the bifurcated derivative. The bifurcated derivative is carried at fair value with changes recorded in noninterest income and reported on our consolidated balance sheet as a derivative asset or liability. The accounting for the remaining host contract is the same as other assets and liabilities of a similar type and reported on our consolidated balance sheet based upon the accounting classification of the instrument. COUNTERPARTY CREDIT RISK AND NETTING By using derivatives, we are exposed to counterparty credit risk, which is the risk that counterparties to the derivative contracts do not perform as expected. If a counterparty fails to perform, our counterparty credit risk is equal to the amount reported as a derivative asset on our consolidated balance sheet. The amounts reported as a derivative asset are derivative contracts in a gain position, and to the extent subject to legally enforceable master netting arrangements, net of derivatives in a loss position with the same counterparty and cash collateral received. We minimize counterparty credit risk through credit approvals, limits, monitoring procedures, executing master netting arrangements and obtaining collateral, where appropriate. Counterparty credit risk related to derivatives is considered in determining fair value and our assessment of hedge effectiveness. To the extent derivatives subject to master netting arrangements meet the applicable requirements, including determining the legal enforceability of the arrangement, it is our policy to present derivative balances and related cash collateral amounts net on our consolidated balance sheet. We incorporate adjustments to reflect counterparty credit risk (credit valuation adjustments (CVA)) in determining the fair value of our derivatives. CVA, which considers the effects of enforceable master netting agreements and collateral arrangements, reflects market-based views of the credit quality of each counterparty. We estimate CVA based on observed credit spreads in the credit default swap market and indices indicative of the credit quality of the counterparties to our derivatives. Cash collateral exchanged related to our interest rate derivatives, and certain commodity and equity derivatives, with centrally cleared counterparties is recorded as a reduction of the derivative fair value asset and liability balances, as opposed to separate non-derivative receivables or payables. This cash collateral, also referred to as variation margin, is exchanged based upon derivative fair value changes, typically on a one-day lag. For additional information on our derivatives and hedging activities, see Note 14 (Derivatives).
Pension Accounting	Pension Accounting We sponsor a frozen noncontributory qualified defined benefit retirement plan, the Wells Fargo & Company Cash Balance Plan (Cash Balance Plan), which covers eligible employees of Wells Fargo. We also sponsor nonqualified defined benefit plans that provide supplemental defined benefit pension benefits to certain eligible employees. We account for our defined benefit pension plans using an actuarial model. Principal assumptions used in determining the net periodic pension cost and the pension obligation include the discount rate, the expected long-term rate of return on plan asset s and projected mortality rates. A single weighted-average discount rate is used to estimate the present value of our future pension benefit obligations. We determine the discount rate using a yield curve derived from a broad-based population of high-quality corporate bonds with maturity dates that closely match the estimated timing of the expected benefit payments. On December 31, 2021, we changed the method used to estimate the interest cost component of pension expense for our principal defined benefit and postretirement plans to the full yield curve approach. The full yield curve approach aligns specific spot rates along the yield curve to the projected benefit payment cash flows. This change does not affect the measurement of our pension obligation as the change in interest cost is offset in the actuarial gain (loss). We accounted for this change prospectively as a change in estimate to our pension expense. Previously, we estimated the interest cost component utilizing a single weighted-average discount rate. We made this change to improve the correlation between the yield curve and the projected benefit payment cash flows. The determination of our expected long-term rate of return on plan assets is highly quantitative by nature. We evaluate the current asset allocations and expected returns using forward-looking capital market assumptions. We use the resulting projections to derive a baseline expected rate of return for the Cash Balance Plan’s prescribed asset mix. Mortality rate assumptions are based on mortality tables published by the Society of Actuaries adjusted to reflect our specific experience. At year end, we re-measure our defined benefit plan liabilities and related plan assets and recognize any resulting actuarial gain or loss in OCI. We generally amortize net actuarial gain or loss in excess of a 5% corridor from AOCI into net periodic pension cost over the estimated average remaining participation period, which at December 31, 2022, is 18 years. See Note 21 (Employee Benefits) for additional information on our pension accounting.
Income Taxes	Income Taxes We file income tax returns in the jurisdictions in which we operate and evaluate income tax expense in two components: current and deferred income tax expense. Current income tax expense represents our estimated taxes to be paid or refunded for the current period and includes income tax expense related to uncertain tax positions. Uncertain tax positions that meet the more likely than not recognition threshold are measured to determine the amount of benefit to recognize. An uncertain tax position is measured at the largest amount of benefit that management believes has a greater than 50% likelihood of realization upon settlement. Tax benefits not meeting our realization criteria represent unrecognized tax benefits. Deferred income taxes are based on the balance sheet method and deferred income tax expense results from changes in deferred tax assets and liabilities between periods. Under the balance sheet method, the net deferred tax asset or liability is based on the tax effects of the differences between the book and tax basis of assets and liabilities, and enacted changes in tax rates and laws are recognized in the period in which they occur. Deferred tax assets are recognized subject to management’s judgment that realization is more likely than not. A valuation allowance reduces deferred tax assets to the realizable amount.
Stock-Based Compensation	Stock-Based Compensation Our long-term incentive plans provide awards for employee services in various forms, such as restricted share rights (RSRs) and performance share awards (PSAs). Stock-based awards are measured at fair value on the grant date. The cost is recognized in personnel expense, net of actual forfeitures, in o ur consolidated statement of income normally over the vesting period of the award; awards with graded vesting are expensed on a straight-line method. Awards to employees who are retirement eligible at the grant date are subject to immediate expensing upon grant. Awards to employees who become retirement eligible before the final vesting date are expensed between the grant date and the date the employee becomes retirement eligible. Except for retirement and other limited circumstances, RSRs are canceled when employment ends. PSAs and certain RSRs granted in 2020 included discretionary conditions that can result in forfeiture and are measured at fair value initially and subsequently until the discretionary conditions end. For these awards, the associated compensation expense fluctuates with changes in our stock price. Awards granted in 2022 and 2021 no longer included these discretionary conditions and are not adjusted for subsequent changes in stock price. For PSAs, compensation expense also fluctuates based on the estimated outcome of meeting the performance conditio ns. The total expense that will be recognized on these awards is finalized upon the completion of the performance period. For additional information on our stock-based employee compensation plans, see Note 12 (Common Stock and Stock Plans).
Earnings Per Common Share	Earnings Per Common Share We compute earnings per common share by dividing net income applicable to common stock (net income less dividends on preferred stock and the excess of consideration transferred over carrying value of preferred stock redeemed, if any) by the average number of common shares outstanding during the period. We compute diluted earnings per common share using net income applicable to common stock and adding the effect of common stock equivalents (e.g., restricted share rights) that are dilutive to the average number of common shares outstanding during the period.
Fair Value of Assets and Liabilities	Fair Value of Assets and Liabilities Fair value represents the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is based on an exit price notion that maximizes the use of observable inputs and minimizes the use of unobservable inputs. We measure our assets and liabilities at fair value when we are required to record them at fair value, when we have elected the fair value option, and to fulfill fair value disclosure requirements. Assets and liabilities are recorded at fair value on a recurring or nonrecurring basis. Assets and liabilities that are recorded at fair value on a recurring basis require a fair value measurement at each reporting period. Assets and liabilities that are recorded at fair value on a nonrecurring basis are adjusted to fair value only as required through the application of an accounting method such as LOCOM, write-downs of individual assets, or application of the measurement alternative for certain nonmarketable equity securities. We classify our assets and liabilities measured at fair value based upon a three-level hierarchy that assigns the highest priority to unadjusted quoted prices in active markets and the lowest priority to unobservable inputs. The three levels are as follows: • Level 1 – Valuation is based upon quoted prices for identical instruments traded in active markets. • Level 2 – Valuation is based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market. • Level 3 – Valuation is generated from techniques that use significant assumptions that are not observable in the market. These unobservable assumptions reflect our estimates of assumptions that market participants would use in pricing the asset or liability. Valuation techniques include use of discounted cash flow models, market comparable pricing, option pricing models, and similar techniques. We monitor the availability of observable market data to assess the appropriate classification of financial instruments within the fair value hierarchy and transfers between Level 1, Level 2, and Level 3 accordingly. Observable market data includes but is not limited to quoted prices and market transactions. Changes in economic conditions or market liquidity generally will drive changes in availability of observable market data. Changes in availability of observable market data, which also may result in changing the valuation technique used, are generally the cause of transfers between Level 1, Level 2, and Level 3. The amounts reported as transfers represent the fair value as of the beginning of the quarter in which the transfer occurred. See Note 15 (Fair Values of Assets and Liabilities) for a more detailed discussion of the valuation methodologies that we apply to our assets and liabilities.
Subsequent Events	Subsequent Events We have evaluated the effects of events that have occurred subsequent to December 31, 2022 as follows: In January 2023, we reclassified fixed-rate debt securities with an aggregate fair value of $23.2 billion and amortized cost of $23.9 billion from held-to-maturity to available-for-sale and designated $20.1 billion in notional amounts of interest rate swaps as fair value hedges using the portfolio layer method, in connection with the adoption of ASU 2022-01, Derivatives and Hedging (Topic 815): Fair Value Hedging – Portfolio Layer Method. The transfer of debt securities was recorded at fair value and resulted in $566 million of unrealized losses associated with available-for-sale debt securities being recorded to other comprehensive income, net of deferred taxes. Except as discussed above, there have been no material events that would require recognition in our 2022 consolidated financial statements or disclosure in the Notes to the consolidated financial statements.

Securities	Trading Activities We engage in trading activities to accommodate the investment and risk management activities of our customers. These activities predominantly occur in our Corporate and Investment Banking reportable operating segment. Trading assets and liabilities include debt securities, equity securities, loans held for sale, derivatives and short sales, which are reported within our consolidated balance sheet based on the accounting classification of the instrument. In addition, debt securities that are held for investment purposes that we have elected to account for under the fair value method, are classified as trading. Our trading assets and liabilities are carried on our consolidated balance sheet at fair value with changes in fair value recognized in net gains from trading and securities within noninterest income. Interest income and interest expense are recognized in net interest income. Customer accommodation trading activities include our actions as an intermediary to buy and sell financial instruments and market-making activities. We also take positions to manage our exposure to customer accommodation activities. We hold financial instruments for trading in long positions, as well as short positions, to facilitate our trading activities. As an intermediary, we interact with market buyers and sellers to facilitate the purchase and sale of financial instruments to meet the anticipated or current needs of our customers. For example, we may purchase or sell a derivative to a customer who wants to manage interest rate risk exposure. We typically enter into an offsetting derivative or security position to manage our exposure to the customer transaction. We earn income based on the transaction price difference between the customer transaction and the offsetting position, which is reflected in earnings where the fair value changes and related interest income and expense of the positions are recorded. Our market-making activities include taking long and short trading positions to facilitate customer order flow. These activities are typically executed on a short-term basis. As a market-maker we earn income due to: (1) the difference between the price paid or received for the purchase and sale of the security (bid-ask spread), (2) the net interest income of the
Debt securities [Member]
Significant Accounting Policies [Line Items]
Securities	Available-for-Sale and Held-to-Maturity Debt Securities Our investments in debt securities that are not held for trading purposes are classified as either available-for-sale (AFS) or held-to-maturity (HTM). Investments in debt securities for which the Company does not have the positive intent and ability to hold to maturity are classified as AFS. AFS debt securities are measured at fair value, with unrealized gains and losses reported in accumulated other comprehensive income (AOCI). The amount reported in other comprehensive income (OCI) is net of the allowance for credit losses (ACL) and applicable income taxes. Investments in debt securities for which the Company has the positive intent and ability to hold to maturity are classified as HTM. HTM debt securities are measured at amortized cost, net of ACL. See Note 3 (Available-for-Sale and Held-to-Maturity Debt Securities) for additional information. INTEREST INCOME AND GAIN/LOSS RECOGNITION Unamortized premiums and discounts are recognized in interest income over the contractual life of the security using the effective interest method, except for purchased callable debt securities carried at a premium. For purchased callable debt securities carried at a premium, the premium is amortized into interest income to the next call date using the effective interest method. As principal repayments are received on securities (e.g., mortgage-backed securities (MBS)), a proportionate amount of the related premium or discount is recognized in income so that the effective interest rate on the remaining portion of the security continues unchanged. We recognize realized gains and losses on the sale of debt securities in net gains from trading and securities within noninterest income using the specific identification method. IMPAIRMENT AND CREDIT LOSSES Unrealized losses on AFS debt securities are driven by a number of factors, including changes in interest rates and credit spreads which impact most types of debt securities, and prepayment rates which impact MBS and collateralized loan obligations (CLO). Additional considerations for certain types of AFS debt securities include: • Debt securities of U.S. Treasury and federal agencies, including federal agency MBS, are not impacted by credit movements given the explicit or implicit guarantees provided by the U.S. government. • Debt securities of U.S. states and political subdivisions are most impacted by changes in the relationship between municipal and term funding credit curves rather than by changes in the credit quality of the underlying securities. • Structured securities, such as MBS and CLO, are also impacted by changes in projected collateral losses of assets underlying the security. For AFS debt securities where fair value is less than amortized cost basis, we recognize impairment in earnings if we have the intent to sell the security or if it is more likely than not that we will be required to sell the security before recovery of its amortized cost basis. Impairment is recognized in net gains on trading and securities within noninterest income equal to the difference between the amortized cost basis, net of ACL, and the fair value of the AFS debt security. Following the recognition of this impairment, the AFS debt security’s new amortized cost basis is fair value. For AFS debt securities where fair value is less than amortized cost basis where we did not recognize impairment in earnings, we record an ACL as of the balance sheet date to the extent unrealized loss is due to credit losses. See the “Allowance for Credit Losses” section in this Note for our accounting policies relating to the ACL for debt securities, which also includes debt securities classified as HTM. TRANSFERS BETWEEN CATEGORIES OF DEBT SECURITIES Transfers of debt securities from the AFS to HTM classification are recorded at fair value, and accordingly the amortized cost of the security transferred to HTM is adjusted to fair value. Unrealized gains or losses reported in AOCI at the transfer date are amortized into earnings over the same period as the unamortized premiums and discounts using the effective interest method. Any ACL previously recorded under the AFS debt security model is reversed and an ACL under the HTM debt security model is re-established. The reversal and re-establishment of the ACL are recorded in provision for credit losses. Transfers of debt securities from the HTM to AFS classification are recorded at fair value. The HTM amortized cost (excluding any ACL previously recorded under the HTM debt security model) becomes the AFS amortized cost, and the debt security is remeasured at fair value with the unrealized gains and losses reported in OCI. Any ACL previously recorded under the HTM debt security model is reversed and an ACL under the AFS debt security model is re-established. The reversal and re-establishment of the ACL are recorded in provision expense. Transfers from HTM to AFS are only expected to occur under limited circumstances. NONACCRUAL AND PAST DUE, AND CHARGE-OFF POLICIES We generally place debt securities on nonaccrual status using factors similar to those described for loans. When we place a debt security on nonaccrual status, we reverse the accrued unpaid interest receivable against interest income and suspend the amortization of premiums and accretion of discounts. If the ultimate collectability of the principal is in doubt on a nonaccrual debt security, any cash collected is first applied to reduce the security’s amortized cost basis to zero, followed by recovery of amounts previously charged off, and subsequently to interest income. Generally, we return a debt security to accrual status when all delinquent interest and principal become current under the contractual terms of the security and collectability of remaining principal and interest is no longer doubtful. Our debt securities are considered past due when contractually required principal or interest payments have not been made on the due dates. Our charge-off policy for debt securities are similar to those described for loans. Subsequent to charge-off, the debt security will be designated as nonaccrual and follow the process described above for any cash received.
Equity securities [Member]
Significant Accounting Policies [Line Items]
Securities	Equity Securities Equity securities exclude investments that represent a controlling interest in the investee. Marketable equity securities have readily determinable fair values and are predominantly used in our trading activities. Marketable equity securities are recorded at fair value with realized and unrealized gains and losses recognized in net gains from trading and securities in noninterest income. Dividend income from marketable equity securities is recognized in interest income. N onmarketable equity securities do not have readily determinable fair values. These securities are accounted for under one of the following accounting methods: • Fair value through net income: This method is an election. The securities are recorded at fair value with unrealized gains or losses recognized in net gains from trading and securities in noninterest income; • Equity method: This method is applied when we have the ability to exert significant influence over the investee. The securities are recorded at cost and adjusted for our share of the investee’s earnings or losses, less any dividends received and/or impairments. Equity method adjustments for our share of the investee’s earnings or losses are recognized in other noninterest income and dividends are recognized as a reduction of the investment carrying value; • Proportional amortization method: This method is applied to certain low-income housing tax credit (LIHTC) investments. The investments are initially recorded at cost and amortized in proportion to the tax credits received. The amortization of the investments and the related tax impacts are recognized in income tax expense; • Cost method: This method is required for specific securities, such as Federal Reserve Bank stock and Federal Home Loan Bank stock. These securities are held at cost less any impairments; • Measurement alternative: This method is followed by all remaining nonmarketable equity securities. These securities are initially recorded at cost and are remeasured to fair value as of the date of an orderly observable transaction of the same or similar security of the same issuer. These securities are also adjusted for impairments. All realized and unrealized gains and losses, including impairment losses, from nonmarketable equity securities are recognized in net gains from trading and securities in noninterest income. Dividend income from all nonmarketable equity securities, other than equity method securities, is recognized in interest income. Our review for impairment for nonmarketable equity securities not carried at fair value includes an analysis of the facts and circumstances of each security, the intent or requirement to sell the security, the expectations of cash flows, capital needs and the viability of its business model. When the fair value of an equity method or cost method investment is less than its carrying value, we write-down the asset to fair value when we consider declines in value to be other than temporary. When the fair value of an investment accounted for using the measurement alternative is less than its carrying value, we write-down the asset to fair value, without the consideration of anticipated recovery. See Note 4 (Equity Securities) for additional information.

AFS And HTM Debt Securities [Abstract]
Available-for-Sale and Held-to-Maturity Debt Securities Outstanding	Table 3.1 provides the amortized cost, net of the allowance for credit losses (ACL) for debt securities, and fair value by major categories of available-for-sale (AFS) debt securities, which are carried at fair value, and held-to-maturity (HTM) debt securities, which are carried at amortized cost, net of the ACL. 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 for the years ended 2022 and 2021 was insignificant.

Allowance for Credit Losses for Loans	Table 5.5 presents the allowance for credit losses (ACL) for loans, which consists of the allowance for loan losses and the allowance for unfunded credit commitments. The ACL for loans decreased $179 million from December 31, 2021, reflecting reduced uncertainty around the economic impact of the COVID-19 pandemic on our loan portfolio. This decrease was partially offset by loan growth and a less favorable economic environment.

Nonaccrual Loans	Table 5.12 provides loans on nonaccrual status. Nonaccrual loans may have an ACL or a negative allowance for credit losses from expected recoveries of amounts previously written off. Customer payment deferral activities in the residential mortgage portfolio instituted in response to the COVID-19 pandemic could continue to delay the recognition of nonaccrual loans for those residential mortgage customers who would have otherwise moved into nonaccrual status.

TDRs may have multiple types of concessions, but are presented only once in the first modification type based on the order presented in the table above. The reported amounts include loans remodified of $445 million, $737 million, and $1.5 billion for the years ended December 31, 2022, 2021 and 2020, respectively. (2) Other concessions include loans with payment (principal and/or interest) deferral, loans discharged in bankruptcy, loan renewals, term extensions and other interest and noninterest adjustments, but exclude modifications that also forgive principal and/or reduce the contractual interest rate. The reported amounts include loans that are new TDRs that may have COVID-19-related payment deferrals and exclude COVID-19-related payment deferrals on loans previously reported as TDRs given limited current financial effects other than payment deferral. (3) Charge-offs include write-downs of the investment in the loan in the period it is contractually modified. The amount of charge-off will differ from the modification terms if the loan has been charged down prior to the modification based on our policies. In addition, there may be cases where we have a charge-off/down with no legal principal modification. (4) Recorded investment related to interest rate reduction reflects the effect of reduced interest rates on loans with an interest rate concession as one of their concession types, which includes loans reported as a principal primary modification type that also have an interest rate concession. (5) Trial modifications are granted a delay in payments due under the original terms during the trial payment period. However, these loans continue to advance through delinquency status and accrue interest according to their original terms. Any subsequent permanent modification generally includes interest rate related concessions; however, the exact concession type and resulting financial effect are usually not known until the loan is permanently modified. Trial modifications for the period are presented net of previously reported trial modifications that became permanent in the current period.
Defaulted TDRs	Table 5.15 summarizes permanent modification TDRs that have defaulted in the current period within 12 months of their permanent modification date. We are reporting these defaulted TDRs based on a payment default definition of 90 days past due for the commercial portfolio segment and 60 days past due for the consumer portfolio segment.

MSRs may increase upon repurchase due to servicing liabilities associated with these delinquent GNMA loans. (2) Includes sales and transfers of MSRs, which can result in an increase in MSRs if related to portfolios with servicing liabilities. For the year ended December 31, 2022, MSRs decreased $611 million due to the sale of interest-only strips related to excess servicing cash flows from agency residential mortgage-backed securitizations. (3) Includes prepayment rate changes as well as other valuation changes due to changes in mortgage interest rates. To reduce exposure to changes in interest rates, MSRs are economically hedged with derivative instruments. (4) Includes costs to service and unreimbursed foreclosure costs. (5) In 2022, we enhanced our approach for estimating the discount rates to a more dynamic methodology for market curves and volatility, which had a nominal impact. (6) Represents other changes in valuation model inputs or assumptions including prepayment rate estimation changes that are independent of mortgage interest rate changes. (7) Represents the reduction in the MSR fair value for the cash flows expected to be collected during the period, net of income accreted due to the passage of time.
Assumptions and Sensitivity of Residential MSRs	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. Amounts for residential MSRs include purchased servicing rights as well as servicing rights resulting from the transfer of loans. See Note 15 (Fair Values of Assets and Liabilities) for additional information on key assumptions for residential MSRs.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Notional or Contractual Amounts and Fair Values of Derivatives	Table 14.1 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.

(2) Includes originations of mortgage servicing rights and loans held for sale. (3) All assets and liabilities transferred into Level 3 were previously classified within Level 2. (4) All assets and liabilities transferred out of Level 3 are classified as Level 2. During first quarter 2022, we transferred $8.9 billion of non-marketable equity securities and $1.4 billion of related economic hedging derivative assets (equity contracts) out of Level 3 due to our election to measure fair value of these instruments as a portfolio. Under this election, the unit of valuation is the portfolio-level, rather than each individual instrument. The unobservable inputs previously significant to the valuation of the instruments individually are no longer significant, as those unobservable inputs offset under the portfolio election. (5) Includes net unrealized gains (losses) related to assets and liabilities held at period end included in both net income and other comprehensive income. All amounts represent net unrealized gains (losses) included in net income except for $(9) million, $(1) million and $57 million included in other comprehensive income from AFS debt securities for the years ended December 31, 2022, 2021 and 2020, respectively. (6) Included in net gains from trading and securities on our consolidated statement of income. (7) Included in mortgage banking income on our consolidated statement of income.

Valuation Techniques - Recurring Basis	Table 15.3 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 (see discussion in the “Level 3 Asset and Liability Valuation Processes” section within this Note regarding vendor-developed valuations). Weighted averages of inputs are calculated using outstanding unpaid principal balance for cash instruments, such as loans and securities, and notional amounts for derivative instruments.

Valuation Techniques - Nonrecurring Basis	Table 15.6 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 nonmarketable equity securities and private equity and venture capital investments in consolidated portfolio companies.

Fair Value Estimates for Financial Instruments	Table 15.9 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 15.9. 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 $737 million and $1.4 billion at December 31, 2022 and 2021, 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 16.1 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, securities, and loans. 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. Substantially all transfers were related to residential mortgage securitizations with the GSEs or GNMA and resulted in no gain or loss because the loans are measured at fair value on a recurring basis. Additionally, we may transfer certain government insured loans that we previously repurchased. These 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.

Residential MSRs - Assumptions at Securitization Date	Table 16.2 presents the key weighted-average assumptions we used to initially measure residential MSRs recognized during the periods presented. Table 16.2: Residential MSRs – Assumptions at Securitization Date Year ended December 31, 2022 2021 2020 Prepayment rate (1) 12.4 % 13.7 15.4 Discount rate 8.0 5.9 6.5 Cost to service ($ per loan) $ 110 91 96 (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 16.3 presents information about loans that we sold or securitized in which we have ongoing involvement as servicer. Delinquent loans include loans 90 days or more past due and loans in bankruptcy, regardless of delinquency status. 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 16.3 excludes mortgage loans in GSE or GNMA securitizations of $704.5 billion and $736.8 billion at December 31, 2022 and 2021, respectively. Delinquent loans and foreclosed assets related to GSEs and GNMA were $4.6 billion and $10.3 billion at December 31, 2022 and 2021, respectively.

Unconsolidated VIEs	Table 16.4 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 16.4, “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 16.6 presents a summary of financial assets and liabilities of our consolidated VIEs. The carrying value represents assets and liabilities recorded 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.

Pledged Assets and Collateral (Tables)	Dec. 31, 2022
Transfers and Servicing [Abstract]
Pledged Assets	Table 18.1 provides the carrying amount of on-balance sheet pledged assets as well as the fair value of other pledged collateral not recognized on our consolidated balance sheet, which we have received from third parties, have the right to repledge and have repledged. These amounts include assets pledged in transactions accounted for as secured borrowings, which are presented parenthetically on our consolidated balance sheet. TRADING RELATED ACTIVITY Our trading businesses may pledge debt and equity securities in connection with securities sold under agreements to repurchase (repurchase agreements) and securities lending arrangements. The collateral that we pledge related to our trading activities may include our own collateral as well as collateral that we have received from third parties and have the right to repledge. All of the collateral we pledge related to trading activity is eligible to be repledged or sold by the secured party. NON-TRADING RELATED ACTIVITY As part of our liquidity management strategy, we may pledge loans, debt securities, and other financial assets to secure trust and public deposits, borrowings and letters of credit from Federal Home Loan Banks (FHLBs) and the Board of Governors of the Federal Reserve System (FRB) and for other purposes as required or permitted by law or insurance statutory requirements. Substantially all of the non-trading activity pledged collateral is not eligible to be repledged or sold by the secured party. VIE RELATED We pledge assets in connection with various types of transactions entered into with VIEs. These pledged assets can only be used to settle the liabilities of those entities. We also have loans recorded on our consolidated balance sheet which represent certain delinquent loans that are eligible for repurchase from GNMA loan securitizations. See Note 16 (Securitizations and Variable Interest Entities) for additional information on consolidated VIE assets.

Offsetting - Securities and Other Collateralized Financing Activities	Table 18.2 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, and those with a single 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. Generally, these agreements require collateral to exceed the asset or liability recognized on the balance sheet. The following table includes the amount of collateral pledged or received related to exposures subject to enforceable MRAs or MSLAs. While these agreements are typically over-collateralized, U.S. GAAP requires disclosure in this table to limit the reported amount of such collateral to the amount of the related recognized asset or liability for each counterparty. In addition to the amounts included in Table 18.2, we also have balance sheet netting related to derivatives that is disclosed in Note 14 (Derivatives). Table 18.2: Offsetting – Securities and Other Collateralized Financing Activities (in millions) Dec 31, Dec 31, Assets: Resale and securities borrowing agreements Gross amounts recognized $ 114,729 103,140 Gross amounts offset in consolidated balance sheet (1) (24,464) (14,074) Net amounts in consolidated balance sheet (2) 90,265 89,066 Collateral not recognized in consolidated balance sheet (3) (89,592) (88,330) Net amount (4) $ 673 736 Liabilities: Repurchase and securities lending agreements Gross amounts recognized $ 55,054 35,043 Gross amounts offset in consolidated balance sheet (1) (24,464) (14,074) Net amounts in consolidated balance sheet (5) 30,590 20,969 Collateral pledged but not netted in consolidated balance sheet (6) (30,383) (20,820) Net amount (4) $ 207 149 (1) Represents recognized amount of resale and repurchase agreements with counterparties subject to enforceable MRAs that have been offset in our consolidated balance sheet.

(3) Represents the fair value of collateral we have received under enforceable MRAs or MSLAs, limited in the table above to the amount of the recognized asset due from each counterparty. At December 31, 2022 and 2021, we have received total collateral with a fair value of $136.6 billion and $124.4 billion, respectively, all of which we have the right to sell or repledge. These amounts include securities we have sold or repledged to others with a fair value of $59.1 billion and $28.8 billion at December 31, 2022 and 2021, respectively. (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.

Regulatory Capital Requirements and Other Restrictions [Abstract]
Regulatory Capital Information	Table 25.1 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. At December 31, 2022, the Bank and our other insured depository institutions were considered well-capitalized under the requirements of the Federal Deposit Insurance Act.
