Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 1: Summary of Significant Accounting Policies Wells Fargo & Company is a diversified financial services company. We provide banking, investment and mortgage products and services, as well as consumer and commercial finance, through banking locations and offices, the internet and other distribution channels to individuals, businesses and institutions in all 50 states, the District of Columbia, and in countries outside the U.S. When we refer to “Wells Fargo,” “the Company,” “we,” “our” or “us,” we mean Wells Fargo & Company and Subsidiaries (consolidated). Wells Fargo & Company (the Parent) is a financial holding company and a bank holding company. We also hold a majority interest in a real estate investment trust, which has publicly traded preferred stock outstanding. Our accounting and reporting policies conform with U.S. generally accepted accounting principles (GAAP) and practices in the financial services industry. For discussion of our significant accounting policies, see Note 1 (Summary of Significant Accounting Policies) in our Annual Report on Form 10-K for the year ended December 31, 2022 (2022 Form 10-K). There were no material changes to these policies in the first half of 2023. 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 13 (Securitizations and Variable Interest Entities)); • valuations of financial instruments (Note 12 (Fair Values of Assets and Liabilities)); • liabilities for contingent litigation losses (Note 10 (Legal Actions)); • income taxes; and • goodwill impairment (Note 7 (Intangible Assets and Other Assets)). Actual results could differ from those estimates. These unaudited interim financial statements reflect all adjustments that are, in the opinion of management, necessary for a fair statement of the results for the periods presented. These adjustments are of a normal recurring nature, unless otherwise disclosed in this Form 10-Q. The results of operations in the interim financial statements do not necessarily indicate the results that may be expected for the full year. The interim financial information should be read in conjunction with our 2022 Form 10-K. Accounting Standards Adopted in 2023 In 2023, we adopted the following new accounting guidance: • Accounting Standards Update (ASU) 2022-02, Financial Instruments – Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures • ASU 2022-01, Derivatives and Hedging (Topic 815): Fair Value Hedging – Portfolio Layer Method • ASU 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers • ASU 2018-12, Financial Services – Insurance (Topic 944): Targeted Improvements to the Accounting for Long-Duration Contracts and subsequent related updates ASU 2022-02 eliminates the accounting and reporting for troubled debt restructurings (TDRs) by creditors and introduces new required disclosures for loan modifications made to borrowers experiencing financial difficulty. The new required disclosures include information about modifications granted to borrowers experiencing financial difficulty in the form of principal forgiveness, interest rate reductions, other-than-insignificant payment delays, term extensions, or a combination of these modifications. The ASU also requires new disclosures for the financial effects of these modifications and for loan performance in the twelve months following the modification. The Update also amends the guidance for vintage disclosures to require disclosure of current period gross charge-offs by year of origination. See Note 5 (Loans and Related Allowance for Credit Losses) for additional information related to the new disclosures for loan modifications to borrowers experiencing financial difficulty and for gross charge-offs by year of origination, which are provided on a prospective basis. The Update eliminates the requirement to use a discounted cash flow (DCF) approach to measure the allowance for credit losses (ACL) for TDRs and instead allows for the use of a current expected credit loss approach for all loans. Under a current expected credit loss approach, the impact of loan modifications and the subsequent performance of modified loans, including defaults, is reflected in the historical loss data used to calculate expected lifetime credit losses. Upon adoption on January 1, 2023, we discontinued utilizing a DCF approach to measure credit impairment for consumer loans and certain commercial loans previously modified in a TDR and we removed the interest concession component recognized in the ACL. We elected to apply the modified-retrospective transition approach method, resulting in a cumulative effect adjustment to retained earnings upon adoption, which reflects the difference between the pre-modification and post-modification effective interest rates that would have been recognized over the remaining life of the loans as interest income. Upon adoption, we recognized a decrease in our ACL of $429 million, pre-tax, and an increase to our retained earnings of $323 million, after tax. We continue to use a DCF approach for certain non-accruing, non-collateral dependent commercial loans. ASU 2022-01 establishes the portfolio layer method, which expands an entity's ability to achieve fair value hedge accounting for interest rate risk hedges of closed portfolios of financial assets. The Update also provides guidance on the accounting for hedged item basis adjustments under the portfolio layer method. We adopted ASU 2022-01 on January 1, 2023 on a prospective basis. No cumulative effect adjustment to the opening balance of stockholders’ equity was required upon adoption, as impacts to us were reflected prospectively. The portfolio layer method improves our ability to use derivatives to hedge interest rate risk exposures associated with portfolios of financial assets, such as fixed-rate available-for-sale (AFS) debt securities and loans. The Update allows us to hedge a larger proportion of these portfolios by expanding the number and type of derivatives permitted as eligible hedges, as well as by increasing the scope of eligible hedged items to include both prepayable and nonprepayable assets. Unlike other fair value hedging relationships where basis adjustments adjust the carrying amount of the individual hedged item, basis adjustments related to active portfolio layer method hedges are maintained at a portfolio level and not allocated to the individual assets in the portfolio. Upon adoption, any election to designate portfolio layer method hedges is applied prospectively. Additionally, the Update permits a one-time reclassification of debt securities from held-to-maturity (HTM) to AFS classification as long as the securities are designated in a portfolio layer method hedge no later than 30 days after the adoption date. 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 HTM to AFS and designated interest rate swaps with notional amounts of $20.1 billion as fair value hedges using the portfolio layer method. The transfer of debt securities was recorded at fair value and resulted in approximately $566 million of unrealized losses associated with AFS debt securities being recorded to other comprehensive income, net of deferred taxes. See Note 3 (Available-for-Sale and Held-to-Maturity Debt Securities) for additional information about the Company's portfolio layer method hedge basis adjustments and HTM to AFS transfers in connection with adoption of the Update and Note 11 (Derivatives) for disclosures regarding our portfolio layer method hedging relationships. ASU 2021-08 amends Accounting Standards Codification (ASC) 805 – Business Combinations to require entities to recognize and measure contract assets and contract liabilities in a business combination in accordance with ASC 606 – Revenue Recognition. Prior to ASU 2021-08, there was diversity in practice related to recognition treatment, and acquirers generally measured such items at acquisition date fair value. We adopted this Update prospectively on January 1, 2023. This Update did not have a material impact to our consolidated financial statements. ASU 2018-12 changes the accounting for long-duration insurance contracts or contract features that provide benefits to the policyholder in addition to the policyholder’s account value. These features, which the ASU defines as market risk benefits, protect the policyholder to some degree from capital markets risk and expose the insurer or reinsurer to that risk. The ASU requires all market risk benefits to be measured at fair value through earnings with changes in fair value attributable to our own credit risk recognized in other comprehensive income. We reinsure certain variable annuity products for a limited number of insurance clients with guaranteed minimum benefits which are accounted for as market risk benefits under the ASU. Our reinsurance business is no longer entering into new contracts. We utilize a discounted cash flow model to value our market risk benefits. Market risk benefits are level 3 fair value liabilities because they are valued using significant unobservable inputs. The fair value of our market risk benefits is sensitive to changes in fixed income and equity markets, as well as policyholder behavior (e.g., withdrawals, lapses, utilization rate) and changes in mortality assumptions. Beginning first quarter 2023, we use derivative instruments, where feasible, to economically hedge the interest rate and equity markets volatility. The fair value of market risk benefits is measured at the contract level and is recognized in accrued expenses and other liabilities. We recognize changes in fair value for our market risk benefits, excluding the change in fair value related to our own credit risk, in noninterest income along with the changes in fair value of economic hedges. Changes in fair value attributable to our own credit risk are recorded in other comprehensive income. Upon adoption on January 1, 2023, as required under the ASU, we implemented the accounting changes for market risk benefits retrospectively, to the earliest period presented, which resulted in an after-tax cumulative effect adjustment to reduce retained earnings and accumulated other comprehensive income by $176 million and $44 million, respectively, as of January 1, 2022. The ASU also requires more frequent updates for insurance assumptions, mandates the use of a standardized discount rate for traditional long-duration contracts, and simplifies the amortization of deferred acquisition costs. The accounting changes for the liability of future policyholder benefits for traditional long-duration contracts (included in accrued expenses and other liabilities) and deferred acquisition costs (included in other assets) did not have a material impact upon adoption. Table 1.1 presents the impact of adoption to prior period financial statement line items within our consolidated statement of income and consolidated balance sheet for the three and six months ended June 30, 2022, and as of December 31, 2022. These adjustments are also reflected in our consolidated statement of changes in equity and consolidated statement of cash flows.

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.

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 June 30, 2023, and December 31, 2022. 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 June 30, 2023 Total portfolio (1) $ 134,251 99 % $ 272,436 99 % Breakdown by category: Securities of U.S. Treasury and federal agencies (2) $ 103,877 100 % $ 221,110 100 % Securities of U.S. states and political subdivisions 21,374 99 18,997 100 Collateralized loan obligations (3) 3,725 100 29,307 100 All other debt securities (4) 5,275 90 3,022 61 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 (1) 99% were rated AA- and above at both June 30, 2023, and December 31, 2022. (2) Includes federal agency mortgage-backed securities. (3) 100% were rated AA- and above at both June 30, 2023, and December 31, 2022. (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 June 30, 2023, and December 31, 2022. Net charge-offs on debt securities were insignificant in the second quarter and first half of both 2023 and 2022. 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 in the second quarter and first half of both 2023 and 2022. 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.

We have assessed each debt security with gross unrealized losses included in the previous table for credit impairment. As part of that assessment we evaluated and concluded that we do not intend to sell any of the debt securities, and that it is more likely than not that we will not be required to sell, prior to recovery of the amortized cost basis. We evaluate, where necessary, whether credit impairment exists by comparing the present value of the expected cash flows to the debt securities’ amortized cost basis. Credit impairment is recorded as an ACL for debt securities. For descriptions of the factors we consider when analyzing debt securities for impairment as well as methodology and significant inputs used to measure credit losses, see Note 1 (Summary of Significant Accounting Policies) in our 2022 Form 10-K. 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.

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 both June 30, 2023, and December 31, 2022. Outstanding balances exclude accrued interest receivable on loans, except for certain revolving loans, such as credit card loans. See Note 7 (Intangible Assets and Other Assets) for additional information on accrued interest receivable. Amounts considered to be uncollectible are reversed through interest income. During the first half of 2023, we reversed accrued interest receivable of $19 million for our commercial portfolio segment and $118 million for our consumer portfolio segment, compared with $20 million and $65 million, respectively, for the same period a year ago.

Our commercial lending commitments include, but are not limited to, (i) commitments for working capital and general corporate purposes, (ii) financing to customers who warehouse financial assets secured by real estate, consumer, or corporate loans, (iii) financing that is expected to be syndicated or replaced with other forms of long-term financing, and (iv) commercial real estate lending. We also originate multipurpose lending commitments under which commercial customers have the option to draw on the facility in one of several forms, including the issuance of letters of credit, which reduces the unfunded commitment amounts of the facility. The maximum credit risk for these commitments will generally be lower than the contractual amount because these commitments may expire without being used or may be cancelled at the customer’s request. We may reduce or cancel lines of credit in accordance with the contracts and applicable law. Our credit risk monitoring activities include managing the amount of commitments, both to individual customers and in total, and the size and maturity structure of these commitments. We do not recognize an ACL for commitments that are unconditionally cancellable at our discretion. We issue commercial letters of credit to assist customers in purchasing goods or services, typically for international trade. At June 30, 2023, and December 31, 2022, we had $1.2 billion and $1.8 billion, respectively, of outstanding issued commercial letters of credit. See Note 14 (Guarantees and Other Commitments) for additional information on issued standby letters of credit. We may be a fronting bank, whereby we act as a representative for other lenders, and advance funds or provide for the issuance of letters of credit under syndicated loan or letter of credit agreements. Any advances are generally repaid in less than a week and would normally require default of both the customer and another lender to expose us to loss. The contractual amount of our unfunded credit commitments, including unissued letters of credit, is summarized in Table 5.4. The table is presented net of commitments syndicated to others, including the fronting arrangements described above, and excludes issued letters of credit and discretionary amounts where our approval or consent is required prior to any loan funding or commitment increase.

Allowance for Credit Losses Table 5.5 presents the 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 increased $1.2 billion from December 31, 2022, reflecting increases for commercial real estate loans, primarily office loans, as well as for increases in credit card loan balances, partially offset by a decrease for residential mortgage loans related to the adoption of ASU 2022-02, Financial Instruments – Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures .

Credit Quality We monitor credit quality by evaluating various attributes and utilize such information in our evaluation of the appropriateness of the ACL for loans. The following sections provide the credit quality indicators we most closely monitor. The credit quality indicators are generally based on information as of our financial statement date. COMMERCIAL CREDIT QUALITY INDICATORS We manage a consistent process for assessing commercial loan credit quality. Commercial loans are generally subject to individual risk assessment using our internal borrower and collateral quality ratings, which is our primary credit quality indicator. Our ratings are aligned to regulatory definitions of pass and criticized categories with the criticized segmented among special mention, substandard, doubtful and loss categories. Table 5.7 provides the outstanding balances of our commercial loan portfolio by risk category and credit quality information by origination year for term loans. Revolving loans may convert to term loans as a result of a contractual provision in the original loan agreement or if modified for a borrower experiencing financial difficulty. At June 30, 2023, we had $526.6 billion and $29.0 billion of pass and criticized commercial loans, respectively. Gross charge-offs by loan class are included in the following table for the six months ended June 30, 2023, which we monitor as part of our credit risk management practices; however, charge-offs are not a primary credit quality indicator for our loan portfolio.

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. Gross charge-offs by loan class are included in the following tables for the six months ended June 30, 2023, which we monitor as part of our credit risk management practices; however, charge-offs are not a primary credit quality indicator for our loan portfolio. 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 for a borrower experiencing financial difficulty. 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. 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.

The revolving loans converted to term loans in the credit card loan category represent credit card loans with modified terms that require payment over a specific term. For the six months ended June 30, 2023, we had gross charge-offs in the credit card portfolio of $861 million for revolving loans and $43 million for revolving loans converted to term loans.

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 $883 million and $1.0 billion at June 30, 2023, and December 31, 2022, respectively, which included $656 million and $771 million, respectively, of loans that are government insured/guaranteed. Under the Consumer Financial Protection Bureau guidelines, we do not commence the foreclosure process on residential mortgage loans until after the loan is 120 days delinquent. Foreclosure procedures and timelines vary depending on whether the property address resides in a judicial or non-judicial state. Judicial states require the foreclosure to be processed through the state’s courts while non-judicial states are processed without court intervention. Foreclosure timelines vary according to state law. LOANS 90 DAYS OR MORE PAST DUE AND STILL ACCRUING Certain loans 90 days or more past due are still accruing, because they are (1) well-secured and in the process of collection or (2) residential mortgage or consumer loans exempt under regulatory rules from being classified as nonaccrual until later delinquency, usually 120 days past due. Table 5.14 shows loans 90 days or more past due and still accruing by class for loans not government insured/guaranteed.

Our commercial loan modifications may include principal forgiveness, interest rate reductions, payment delays, term extensions, or a combination of these modifications. Commercial loan term extensions have terms that vary based on the borrower’s request and are evaluated by our credit teams on an individual basis. Our consumer loan modifications vary based upon the loan product and the modification program offered to the borrower, and may include interest rate reductions, payment delays, term extensions, principal forbearance or forgiveness, or a combination of these modifications. Generally, our consumer loan modification programs modify the loan terms to achieve payment terms that are more affordable to the borrower and, as a result, increase the likelihood of full repayment of principal and interest. Our residential mortgage loan modification programs may offer a short-term payment deferral based upon the borrower's demonstrated hardship, up to 12 months. If additional assistance is needed after 12 months, the borrower may request another loan modification. Modifications may also include a trial payment period of three months to determine if the borrower can perform in accordance with the proposed permanent loan modification terms. Loans in a trial payment period continue to advance through delinquency status and accrue interest according to their original terms. Loans in a trial payment period are excluded from our loan modification disclosures until the borrower has successfully completed the trial period and the loan modification is formally executed. Residential mortgage loans in a trial payment period totaled $132 million at June 30, 2023. Credit card loan modifications result in a reduction in the credit card interest rate and may be offered on a short-term or long-term basis. A short-term interest rate reduction program reduces the borrower’s interest rate for 12 months. A long-term interest rate reduction program provides a reduction of the interest rate over a fixed five-year term. During the modification period, the borrower’s revolving charge privileges are revoked. Auto loan modifications generally include insignificant (e.g., three months or less) payment deferrals over the loan term. The following disclosures provide information on loan modifications granted to borrowers experiencing financial difficulty in the form of principal forgiveness, interest rate reductions, other-than-insignificant (e.g., greater than three months) payment delays, term extensions or a combination of these modifications, as well as the financial effects of these modifications, and loan performance in the twelve months following the modification. Loans that both modify and are paid off or charged-off during the period, resulting in an amortized cost balance of zero at the end of the period, are not included in the disclosures below. Additionally, where amortized cost balances are presented below, accrued interest receivable is excluded. See Note 7 (Intangible Assets and Other Assets) for additional information on accrued interest receivable. Borrowers experiencing financial difficulty with modified terms mandated by a bankruptcy court are considered contractually modified loans and are included in these disclosures. These disclosures do not include loans discharged by a bankruptcy court as the only concession, which were insignificant for the second quarter and first half of 2023.

Mortgage Banking Activities [Abstract]
Mortgage Banking Activities	Note 6: Mortgage Banking Activities Mortgage banking activities consist of residential and commercial mortgage originations, sales and servicing. We apply the amortization method to commercial MSRs and apply the fair value method to residential MSRs. The amortized cost of commercial MSRs was $1.1 billion and $1.2 billion, with an estimated fair value of $1.9 billion and $2.1 billion, at June 30, 2023 and 2022, 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 Quarter ended June 30, Six months ended June 30, (in millions) 2023 2022 2023 2022 Fair value, beginning of period $ 8,819 8,511 $ 9,310 6,920 Originations/purchases 47 322 95 664 Sales and other (1) (606) (251) (599) (250) Net additions (559) 71 (504) 414 Changes in fair value: Due to valuation inputs or assumptions: Market interest rates (2) 318 949 137 2,648 Servicing and foreclosure costs (3) 1 (9) 2 (12) Discount rates — 31 (25) 86 Prepayment estimates and other (4) (3) (103) (23) (249) Net changes in valuation inputs or assumptions 316 868 91 2,473 Changes due to collection/realization of expected cash flows (5) (325) (287) (646) (644) Total changes in fair value (9) 581 (555) 1,829 Fair value, end of period $ 8,251 9,163 $ 8,251 9,163 (1) In second quarter 2022, MSRs decreased $244 million due to the sale of interest-only strips related to excess servicing cash flows from agency residential mortgage-backed securitizations. (2) Includes prepayment rate changes as well as other valuation changes due to changes in market interest rates. To reduce exposure to changes in interest rates, MSRs are economically hedged with derivative instruments. (3) Includes costs to service and unreimbursed foreclosure costs. (4) Represents other changes in valuation model inputs or assumptions, including prepayment rate estimation changes that are independent of mortgage interest rate changes. (5) Represents the reduction in the MSR fair value for the cash flows expected to be collected during the period, net of income accreted due to the passage of time. Table 6.2 provides key weighted-average assumptions used in the valuation of residential MSRs and sensitivity of the current fair value of residential MSRs to immediate adverse changes in those assumptions. Amounts for residential MSRs include purchased servicing rights as well as servicing rights resulting from the transfer of loans. See Note 12 (Fair Values of Assets and Liabilities) for additional information on key assumptions for residential MSRs. Table 6.2: Assumptions and Sensitivity of Residential MSRs ($ in millions, except cost to service amounts) Jun 30, 2023 Dec 31, 2022 Fair value of interests held $ 8,251 9,310 Expected weighted-average life (in years) 6.2 6.3 Key assumptions: Prepayment rate assumption (1) 9.2 % 9.4 Impact on fair value from 10% adverse change $ 249 288 Impact on fair value from 25% adverse change 595 688 Discount rate assumption 9.2 % 9.1 Impact on fair value from 100 basis point increase $ 316 368 Impact on fair value from 200 basis point increase 608 707 Cost to service assumption ($ per loan) 102 102 Impact on fair value from 10% adverse change 159 171 Impact on fair value from 25% adverse change 397 427 (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) Jun 30, 2023 Dec 31, 2022 Residential mortgage servicing: Serviced and subserviced for others $ 637 681 Owned loans serviced 267 273 Total residential servicing 904 954 Commercial mortgage servicing: Serviced and subserviced for others 562 577 Owned loans serviced 131 133 Total commercial servicing 693 710 Total managed servicing portfolio $ 1,597 1,664 Total serviced for others, excluding subserviced for others $ 1,162 1,246 MSRs as a percentage of loans serviced for others 0.80 % 0.84 Weighted average note rate (mortgage loans serviced for others) 4.44 4.30 At June 30, 2023, and December 31, 2022, we had servicer advances, net of an allowance for uncollectible amounts, of $2.1 billion and $2.5 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 written-off when deemed uncollectible. Table 6.4 presents the components of mortgage banking noninterest income.

Legal Actions	Jun. 30, 2023
Commitments and Contingencies Disclosure [Abstract]
Legal Actions	Note 10: Legal Actions Wells Fargo and certain of our subsidiaries are involved in a number of judicial, regulatory, governmental, arbitration, and other proceedings or investigations concerning matters arising from the conduct of our business activities, and many of those proceedings and investigations expose Wells Fargo to potential financial loss or other adverse consequences. These proceedings and investigations include actions brought against Wells Fargo and/or our subsidiaries with respect to corporate-related matters and transactions in which Wells Fargo and/or our subsidiaries were involved. In addition, Wells Fargo and our subsidiaries may be requested to provide information to or otherwise cooperate with government authorities in the conduct of investigations of other persons or industry groups. We establish accruals for legal actions when potential losses associated with the actions become probable and the costs can be reasonably estimated. For such accruals, we record the amount we consider to be the best estimate within a range of potential losses that are both probable and estimable; however, if we cannot determine a best estimate, then we record the low end of the range of those potential losses. There can be no assurance as to the ultimate outcome of legal actions, including the matters described below, and the actual costs of resolving legal actions may be substantially higher or lower than the amounts accrued for those actions. 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. Shareholders 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. On May 1, 2023, the court granted preliminary approval of an agreement pursuant to which the Company agreed to pay $300 million to resolve this action. Additionally, a number of other lawsuits were filed by non-governmental parties seeking damages or other remedies related to these CPI policies and related to the unused portion of guaranteed automobile protection (GAP) waiver or insurance agreements. As previously disclosed, the Company entered into various settlements to resolve these lawsuits, while others were 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. 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. On May 16, 2023, the court granted preliminary approval of an agreement pursuant to which the Company agreed to pay $1.0 billion to resolve this action. Allegations related to the Company’s efforts to comply with these three consent orders are also among the subjects of shareholder derivative lawsuits filed in California state and federal court. 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 and in California state court. 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 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 March 15, 2023, the Second Circuit affirmed the damages class settlement. Settlement objector merchants filed a petition for a rehearing by the Second Circuit en banc, which was denied. 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. 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. The Company is in resolution discussions with these agencies, although there can be no assurance as to the outcome of these discussions. RMBS TRUSTEE LITIGATION In December 2014, Phoenix Light SF Limited (Phoenix Light) and certain related entities filed a complaint in the United States District Court for the Southern District of New York alleging claims against Wells Fargo Bank, N.A., in its capacity as trustee for a number of residential mortgage-backed securities (RMBS) trusts. Complaints raising similar allegations have been filed by Commerzbank AG in the Southern District of New York, IKB International and IKB Deutsche Industriebank in New York state court, and Park Royal I LLC and Park Royal II LLC in New York state court. In each case, the plaintiffs allege that Wells Fargo Bank, N.A., as trustee, caused losses to investors, and plaintiffs assert causes of action based upon, among other things, the trustee’s alleged failure to notify and enforce repurchase obligations of mortgage loan sellers for purported breaches of representations and warranties, notify investors of alleged events of default, and abide by appropriate standards of care following alleged events of default. In July 2022, the district court dismissed Phoenix Light’s claims and certain of the claims asserted by Commerzbank AG, and subsequently entered judgment in each case in favor of Wells Fargo Bank, N.A. In August 2022, Phoenix Light and Commerzbank AG each appealed the district court’s decision to the United States Court of Appeals for the Second Circuit. Phoenix Light dismissed its appeal in May 2023, terminating its case. The Company previously settled two class actions filed by institutional investors and an action filed by the National Credit Union Administration with similar allegations. SEMINOLE TRIBE TRUSTEE LITIGATION The Seminole Tribe of Florida filed a complaint in Florida state court alleging that Wells Fargo, as trustee, charged excess fees in connection with the administration of a minor’s trust and failed to invest the assets of the trust prudently. The complaint was later amended to include three individual current and former beneficiaries as plaintiffs and to remove the Tribe as a party to the case. 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 $1.5 billion as of June 30, 2023. The outcomes of legal actions are unpredictable and subject to significant uncertainties, and it is inherently difficult to determine whether any loss is probable or even possible. It is also inherently difficult to estimate the amount of any loss and there may be matters for which a loss is probable or reasonably possible but not currently estimable. Accordingly, actual losses may be in excess of the established accrual or the range of reasonably possible loss. Based on information currently available, advice of counsel, available insurance coverage, and established reserves, Wells Fargo believes that the eventual outcome of the actions against Wells Fargo and/or its subsidiaries will not, individually or in the aggregate, have a material adverse effect on Wells Fargo’s consolidated financial condition. However, it is possible that the ultimate resolution of a matter, if unfavorable, may be material to Wells Fargo’s results of operations for any particular period.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives	Note 11: Derivatives We use derivatives to manage exposure to market risk, including interest rate risk, credit risk and foreign currency risk, and to assist customers with their risk management objectives. We designate certain derivatives as hedging instruments in qualifying hedge accounting relationships (fair value or cash flow hedges). Our remaining derivatives consist of economic hedges that do not qualify for hedge accounting and derivatives held for customer accommodation trading or other purposes. For additional information on our derivatives activities, see Note 14 (Derivatives) in our 2022 Form 10-K. Table 11.1 presents the total notional or contractual amounts and fair values for our derivatives. Derivative transactions can be measured in terms of the notional amount, but this amount is not recorded on our consolidated balance sheet and is not, when viewed in isolation, a meaningful measure of the risk profile of the instruments. The notional amount is generally not exchanged, but is used only as the basis on which derivative cash flows are determined.

For additional information, 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 11.2 provides information on the fair values of derivative assets and liabilities subject to enforceable master netting arrangements, the balance sheet netting adjustments and the resulting net fair value amount recorded on our consolidated balance sheet, as well as the non-cash collateral associated with such arrangements. In addition to the netting amounts included in the table, we also have balance sheet netting related to resale and repurchase agreements that are disclosed within Note 15 (Pledged Assets and Collateral).

(2) In first quarter 2023, we adopted ASU 2018-12 – Financial Services – Insurance (Topic 944): Targeted Improvements to the Accounting for Long-Duration Contracts . For additional information, see Note 1 (Summary of Significant Accounting Policies). 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 (AFS) debt securities due to changes in interest rates, foreign currency rates, or both. For certain fair value hedges of interest rate risk, we use the portfolio layer method to hedge stated amounts of closed portfolios of AFS debt securities. For certain fair value hedges of foreign currency risk, changes in fair value of cross-currency swaps attributable to changes in cross-currency basis spreads are excluded from the assessment of hedge effectiveness and recorded in other comprehensive income (OCI). See Note 20 (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 $947 million pre-tax of deferred net losses related to cash flow hedges in OCI at June 30, 2023, will be reclassified into net interest income during the next twelve months. For cash flow hedges as of June 30, 2023, 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 9 years. For additional information on our accounting hedges, see Note 1 (Summary of Significant Accounting Policies) in our 2022 Form 10-K. Table 11.3 and Table 11.4 show the net gains (losses) related to derivatives in cash flow and fair value hedging relationships, respectively.

(5) The balance includes cumulative basis adjustments of $(224) million for hedged items currently designated as of June 30, 2023, related to certain AFS debt securities designated as the hedged item in a fair value hedge using the portfolio layer method. At June 30, 2023, the aggregated designated hedged items using the portfolio layer method had a carrying amount of $23.0 billion from closed portfolios of financial assets totaling $26.1 billion. 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. For additional information on our derivatives activities, see Note 14 (Derivatives) in our 2022 Form 10-K.

For additional information, 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 11.7 provides details of sold credit derivatives. Table 11.7: Sold Credit Derivatives Notional amount (in millions) Protection sold Protection sold – non-investment grade June 30, 2023 Credit default swaps $ 14,273 1,677 Risk participation swaps 6,460 6,250 Total credit derivatives $ 20,733 7,927 December 31, 2022 Credit default swaps $ 12,733 1,860 Risk participation swaps 6,728 6,518 Total credit derivatives $ 19,461 8,378 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 11.8 illustrates our exposure to OTC bilateral derivative contracts with credit-risk contingent features, collateral we have posted, and the additional collateral we would be required to post if the credit rating of our debt was downgraded below investment grade.

Fair Value Disclosures [Abstract]
Fair Values of Assets and Liabilities	Note 12: Fair Values of Assets and Liabilities We use fair value measurements to record fair value adjustments to certain assets and liabilities and to fulfill fair value disclosure requirements. Assets and liabilities recorded at fair value on a recurring basis, such as derivatives, residential MSRs, and trading or AFS debt securities, are presented in Table 12.1 in this Note. Additionally, from time to time, we record fair value adjustments on a nonrecurring basis. These nonrecurring adjustments typically involve application of lower of cost or fair value (LOCOM) accounting, write-downs of individual assets or application of the measurement alternative for nonmarketable equity securities. Assets recorded at fair value on a nonrecurring basis are presented in Table 12.4 in this Note. We provide in Table 12.9 estimates of fair value for financial instruments that are not recorded at fair value, such as loans and debt liabilities carried at amortized cost. See Note 1 (Summary of Significant Accounting Policies) in our 2022 Form 10-K for discussion of how we determine fair value. For descriptions of the valuation methodologies we use for assets and liabilities recorded at fair value on a recurring or nonrecurring basis, see Note 15 (Fair Values of Assets and Liabilities) in our 2022 Form 10-K. FAIR VALUE HIERARCHY We classify our assets and liabilities recorded at fair value as either Level 1, 2, or 3 in the fair value hierarchy. The highest priority (Level 1) is assigned to valuations based on unadjusted quoted prices in active markets and the lowest priority (Level 3) is assigned to valuations based on significant unobservable inputs. See Note 1 (Summary of Significant Accounting Policies) in our 2022 Form 10-K for a detailed description of the fair value hierarchy. In the determination of the classification of financial instruments in Level 2 or Level 3 of the fair value hierarchy, we consider all available information, including observable market data, indications of market liquidity and orderliness, and our understanding of the valuation techniques and significant inputs used. This determination is ultimately based upon the specific facts and circumstances of each instrument or instrument category and judgments are made regarding the significance of the unobservable inputs to the instruments’ fair value measurement in its entirety. If unobservable inputs are considered significant, the instrument is classified as Level 3. We do not classify nonmarketable equity securities in the fair value hierarchy if we use the non-published net asset value (NAV) per share (or its equivalent) as a practical expedient to measure fair value. Marketable equity securities with published NAVs are classified in the fair value hierarchy.

Net gains (losses) included in other comprehensive income for AFS debt securities were $(3) million and $(19) million for the second quarter and first half of 2023, respectively, and $(6) million and $(27) million for the second quarter and first half of 2022, respectively. Net gains (losses) included in other comprehensive income for other liabilities were $5 million for both the second quarter and first half of 2023, and $87 million and $101 million for the second quarter and first half of 2022, respectively. (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) All amounts represent net unrealized gains (losses) related to assets and liabilities held at period end included in net income except for AFS debt securities and other liabilities which also included net unrealized gains (losses) related to assets and liabilities held at period end in other comprehensive income. Net unrealized gains (losses) included in other comprehensive income for AFS debt securities were $(2) million and $(17) million for the second quarter and first half of 2023, respectively, and $0 for both the second quarter and first half of 2022. Net unrealized gains (losses) included in other comprehensive income for other liabilities were $5 million for both the second quarter and first half of 2023, and $87 million and $101 million for the second quarter and first half of 2022, respectively.

For additional information, see Note 1 (Summary of Significant Accounting Policies). Table 12.3 provides quantitative information about the valuation techniques and significant unobservable inputs used in the valuation of our Level 3 assets and liabilities measured at fair value on a recurring basis. The significant unobservable inputs for Level 3 assets inherent in the fair values obtained from third-party vendors are not included in the table, as the specific inputs applied are not provided by the vendor (for additional information on vendor-developed valuations, see Note 15 (Fair Values of Assets and Liabilities) in our 2022 Form 10-K). Weighted averages of inputs are calculated using outstanding unpaid principal balance for cash instruments, such as loans and securities, and notional amounts for derivative instruments.

Assets and Liabilities Recorded at Fair Value on a Nonrecurring Basis We may be required, from time to time, to measure certain assets at fair value on a nonrecurring basis in accordance with GAAP. These adjustments to fair value usually result from application of LOCOM accounting, write-downs of individual assets, or application of the measurement alternative for certain nonmarketable equity securities. Table 12.4 provides the fair value hierarchy and fair value at the date of the nonrecurring fair value adjustment for all assets that were still held as of June 30, 2023, and December 31, 2022, and for which a nonrecurring fair value adjustment was recorded during the six months ended June 30, 2023, and the year ended December 31, 2022.

Table 12.6 provides quantitative information about the valuation techniques and significant unobservable inputs used in the valuation of our Level 3 assets that are measured at fair value on a nonrecurring basis and determined using an internal model. The table is limited to financial instruments that had nonrecurring fair value adjustments during the periods presented. Weighted averages of inputs are calculated using outstanding unpaid principal balance for cash instruments, such as loans, and carrying value prior to the nonrecurring fair value measurement for nonmarketable equity securities and private equity and venture capital investments in consolidated portfolio companies.

(2) Represents private equity and venture capital investments in consolidated portfolio companies. Fair Value Option The fair value option is an irrevocable election, generally only permitted upon initial recognition of financial assets or liabilities, to measure eligible financial instruments at fair value with changes in fair value reflected in earnings. We may elect the fair value option to align the measurement model with how the financial assets or liabilities are managed or to reduce complexity or accounting asymmetry. Following is a discussion of the portfolios for which we elected the fair value option. For additional information, including the basis for our fair value option elections, see Note 15 (Fair Values of Assets and Liabilities) in our 2022 Form 10-K. Table 12.7 reflects differences between the fair value carrying amount of the assets and liabilities for which we have elected the fair value option and the contractual aggregate unpaid principal amount at maturity. Table 12.7: Fair Value Option June 30, 2023 December 31, 2022 (in millions) Fair value carrying amount Aggregate unpaid principal Fair value carrying amount less aggregate unpaid principal Fair value carrying amount Aggregate unpaid principal Fair value carrying amount less aggregate Loans held for sale (1) $ 2,974 3,238 (264) 4,220 4,614 (394) Long-term debt (2) (1,600) (2,147) 547 (1,346) (1,775) 429 (1) Nonaccrual loans and loans 90 days or more past due and still accruing included in LHFS for which we have elected the fair value option were insignificant at June 30, 2023, and December 31, 2022.

Table 12.8 reflects amounts included in earnings related to initial measurement and subsequent changes in fair value, by income statement line item, for assets and liabilities for which the fair value option was elected. Amounts recorded in net interest income are excluded from the table below.

These impacts are recorded within the debit valuation adjustments (DVA) in OCI. See Note 20 (Other Comprehensive Income) for additional information. Disclosures about Fair Value of Financial Instruments Table 12.9 presents a summary of fair value estimates for financial instruments that are not carried at fair value on a recurring basis. Some financial instruments are excluded from the scope of this table, such as certain insurance contracts, certain nonmarketable equity securities, and leases. This table also excludes assets and liabilities that are not financial instruments such as the value of the long-term relationships with our deposit, credit card and trust customers, MSRs, premises and equipment, goodwill and deferred taxes. Loan commitments, standby letters of credit and commercial and similar letters of credit are not included in Table 12.9. A reasonable estimate of the fair value of these instruments is the carrying value of deferred fees plus the allowance for unfunded credit commitments, which totaled $622 million and $737 million at June 30, 2023, and December 31, 2022, respectively. The total of the fair value calculations presented does not represent, and should not be construed to represent, the underlying fair value of the Company.

Securitizations and Variable Interest Entities [Abstract]
Securitizations and Variable Interest Entities	Note 13: Securitizations and Variable Interest Entities Involvement with Variable Interest Entities (VIEs) In the normal course of business, we enter into various types of on- and off-balance sheet transactions with special purpose entities (SPEs), which are corporations, trusts, limited liability companies or partnerships that are established for a limited purpose. SPEs are often formed in connection with securitization transactions whereby financial assets are transferred to an SPE. SPEs formed in connection with securitization transactions are generally considered variable interest entities (VIEs). The VIE may alter the risk profile of the asset by entering into derivative transactions or obtaining credit support, and issues various forms of interests in those assets to investors. When we transfer financial assets from our consolidated balance sheet to a VIE in connection with a securitization, we typically receive cash and sometimes other interests in the VIE as proceeds for the assets we transfer. In certain transactions with VIEs, we may retain the right to service the transferred assets and repurchase the transferred assets if the outstanding balance of the assets falls below the level at which the cost to service the assets exceed the benefits. In addition, we may purchase the right to service loans transferred to a VIE by a third party. In connection with our securitization or other VIE activities, we have various forms of ongoing involvement with VIEs, which may include: • underwriting securities issued by VIEs and subsequently making markets in those securities; • providing credit enhancement on securities issued by VIEs through the use of letters of credit or financial guarantees; • entering into other derivative contracts with VIEs; • holding senior or subordinated interests in VIEs; • acting as servicer or investment manager for VIEs; • providing administrative or trustee services to VIEs; and • providing seller financing to VIEs. Loan Sales and Securitization Activity We periodically transfer consumer and commercial loans and other types of financial assets in securitization and whole loan sale transactions. MORTGAGE LOANS SOLD TO 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. When we do not repurchase these loans, they are recorded on our consolidated balance sheet and pledged to the GNMA securitization. We repurchased loans of $99 million and $191 million, during the second quarter and first half of 2023, respectively, and $564 million and $1.5 billion during the second quarter and first half of 2022, respectively. In 2022, these predominantly represented repurchases of government insured loans. At June 30, 2023, and December 31, 2022, we recorded assets and related liabilities of $940 million and $743 million, 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 June 30, 2023, and December 31, 2022, our liability for these repurchase and recourse arrangements was $162 million and $167 million, respectively, and the maximum exposure to loss was $13.8 billion at both June 30, 2023, and December 31, 2022. 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 and account for the transfers as sales. We also typically retain the right to service the loans and may hold other beneficial interests issued by the 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. We do not consolidate the VIE because the most significant decisions impacting the performance of the VIE are generally made by the special servicer or the controlling class security holder. For our residential nonconforming mortgage loan securitizations accounted for as sales, we either do not hold variable interests that we consider potentially significant or are not the primary servicer for a majority of the VIE assets. WHOLE LOAN SALE TRANSACTIONS We may also sell whole loans to VIEs where we have continuing involvement in the form of financing. We account for these transfers as sales, and do not consolidate the VIEs as we do not have the power to direct the most significant activities of the VIEs. Table 13.1 presents information about transfers of assets during the periods presented for which we recorded the transfers as sales and have continuing involvement with the transferred assets. In connection with these transfers, we received proceeds and recorded servicing assets and securities. Each of these interests are initially measured at fair value. Servicing rights are classified as Level 3 measurements, and generally securities are classified as Level 2. The majority of our transfers relate to residential mortgage securitizations with the GSEs or GNMA and generally result 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 13.1: Transfers with Continuing Involvement 2023 2022 (in millions) Residential mortgages Commercial mortgages Residential mortgages Commercial mortgages Quarter ended June 30, Assets sold $ 3,917 1,800 23,817 4,345 Proceeds from transfer (1) 3,917 1,823 23,817 4,411 Net gains (losses) on sale — 23 — 66 Continuing involvement (2): Servicing rights recognized $ 46 16 313 41 Securities recognized (3) — 22 475 33 Six months ended June 30, Assets sold $ 8,378 3,299 49,991 8,378 Proceeds from transfer (1) 8,378 3,363 50,043 8,508 Net gains (losses) on sale — 64 52 130 Continuing involvement (2): Servicing rights recognized $ 93 34 640 70 Securities recognized (3) — 48 2,062 137 (1) Represents cash proceeds and the fair value of non-cash beneficial interests recognized at securitization settlement. (2) Represents assets or liabilities recognized at securitization settlement date related to our continuing involvement in the transferred assets. (3) Represents debt securities obtained at securitization settlement held for investment purposes that are classified as available-for-sale or held-to-maturity. In 2022, these predominantly related 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 $1.8 billion and $3.7 billion during the second quarter and first half of 2023, respectively, and $3.6 billion and $10.3 billion during the second quarter and first half of 2022, respectively. In the normal course of business, we purchase certain non-agency securities at initial securitization or subsequently in the secondary market, which we hold for investment. We also provide seller financing in the form of loans. We received cash flows of $91 million and $141 million during the second quarter and first half of 2023, respectively, and $168 million and $304 million, during the second quarter and first half of 2022, respectively, related to principal and interest payments on these securities and loans, which exclude cash flows related to trading activities. Table 13.2 presents the key weighted-average assumptions we used to initially measure residential MSRs recognized during the periods presented. Table 13.2: Residential MSRs – Assumptions at Securitization Date 2023 2022 Quarter ended June 30, Prepayment rate (1) 16.4 % 10.9 Discount rate 9.4 8.0 Cost to service ($ per loan) $ 176 122 Six months ended June 30, Prepayment rate (1) 17.5 % 11.0 Discount rate 9.6 7.5 Cost to service ($ per loan) $ 185 117 (1) Includes a blend of prepayment speeds and expected defaults. Prepayment speeds are influenced by mortgage interest rates as well as our estimation of drivers of borrower behavior. See Note 12 (Fair Values of Assets and Liabilities) and Note 6 (Mortgage Banking Activities) for additional information on key assumptions for residential MSRs. RESECURITIZATION ACTIVITIES We enter into resecuritization transactions as part of our trading activities to accommodate the investment and risk management activities of our customers. In resecuritization transactions, we transfer trading debt securities to VIEs in exchange for new beneficial interests that are sold to third parties at or shortly after securitization settlement. This activity is performed for customers seeking a specific return or risk profile. Substantially all of our transactions involve the resecuritization of conforming mortgage-backed securities issued by the GSEs or guaranteed by GNMA. We do not consolidate the resecuritization VIEs as we share in the decision-making power with third parties and do not hold significant economic interests in the VIEs other than for market-making activities. During the six months ended June 30, 2023 and 2022, we transferred securities of $6.1 billion and $12.6 billion, respectively, to resecuritization VIEs, and retained securities of $329 million and $525 million, respectively. These amounts are not included in Table 13.1. Related total VIE assets were $111.1 billion and $112.0 billion at June 30, 2023, and December 31, 2022, respectively. As of June 30, 2023, and December 31, 2022, we held $1.3 billion and $793 million of securities, respectively. Sold or Securitized Loans Serviced for Others Table 13.3 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 13.3 excludes mortgage loans sold to and held or securitized by GSEs or GNMA of $637.0 billion and $704.5 billion at June 30, 2023, and December 31, 2022, respectively. Delinquent loans and foreclosed assets related to loans sold to and held or securitized by GSEs or GNMA were $3.4 billion and $4.6 billion at June 30, 2023, and December 31, 2022, respectively. Table 13.3: Sold or Securitized Loans Serviced for Others Net charge-offs Total loans Delinquent loans Six months ended June 30, (in millions) Jun 30, 2023 Dec 31, 2022 Jun 30, 2023 Dec 31, 2022 2023 2022 Commercial $ 66,082 67,029 849 912 67 22 Residential 8,789 9,201 433 501 8 7 Total off-balance sheet sold or securitized loans $ 74,871 76,230 1,282 1,413 75 29 (1) Includes $213 million and $274 million of commercial foreclosed assets and $28 million and $25 million of residential foreclosed assets at June 30, 2023, and December 31, 2022, respectively. Transactions with Unconsolidated VIEs MORTGAGE LOAN SECURITIZATIONS Table 13.4 includes nonconforming mortgage loan securitizations where we originate and transfer the loans to the unconsolidated securitization VIEs that we sponsor. For additional information about these VIEs, see the “Loan Sales and Securitization Activity” section within this Note. Nonconforming mortgage loan securitizations also include commercial mortgage loan securitizations sponsored by third parties where we did not originate or transfer the loans but serve as master servicer and invest in securities that could be potentially significant to the VIE. Conforming loan securitization and resecuritization transactions involving the GSEs and GNMA are excluded from Table 13.4 because we are not the sponsor or we do not have power over the activities most significant to the VIEs. Additionally, due to the nature of the guarantees provided by the GSEs and the FHA and VA, our credit risk associated with these VIEs is limited. For additional information about conforming mortgage loan securitizations and resecuritizations, see the “Loan Sales and Securitization Activity” and “Resecuritization Activities” sections within this Note. COMMERCIAL REAL ESTATE LOANS We may transfer purchased industrial development bonds and GSE credit enhancements to VIEs in exchange for beneficial interests. We may also acquire such beneficial interests in transactions where we do not act as a transferor. We own all of the beneficial interests and may also service the underlying mortgages that serve as collateral to the bonds. The GSEs have the power to direct the servicing and workout activities of the VIE in the event of a default, therefore we do not have control over the key decisions of the VIEs. OTHER VIE STRUCTURES We engage in various forms of structured finance arrangements with other VIEs, including asset-backed finance structures and other securitizations collateralized by asset classes other than mortgages. Collateral may include rental properties, asset-backed securities, student loans and mortgage loans. We may participate in structuring or marketing the arrangements as well as provide financing, service one or more of the underlying assets, or enter into derivatives with the VIEs. We may also receive fees for those services. We are not the primary beneficiary of these structures because we do not have power to direct the most significant activities of the VIEs. Table 13.4 provides a summary of our exposure to the unconsolidated VIEs described above, which includes investments in securities, loans, guarantees, liquidity agreements, commitments and certain derivatives. We exclude certain transactions with unconsolidated VIEs when our continuing involvement is temporary or administrative in nature or insignificant in size. In Table 13.4, “Total VIE assets” represents the remaining principal balance of assets held by unconsolidated VIEs using the most current information available. “Carrying value” is the amount in our consolidated balance sheet related to our involvement with the unconsolidated VIEs. “Maximum exposure to loss” is determined as the carrying value of our investment in the VIEs excluding the unconditional repurchase options that have not been exercised, plus the remaining undrawn liquidity and lending commitments, the notional amount of net written derivative contracts, and generally the notional amount of, or stressed loss estimate for, other commitments and guarantees. Debt, guarantees and other commitments include amounts related to lending arrangements, liquidity agreements, and certain loss sharing obligations associated with loans originated, sold, and serviced under certain GSE programs. “Maximum exposure to loss” represents estimated loss that would be incurred under severe, hypothetical circumstances, for which we believe the possibility is extremely remote, such as where the value of our interests and any associated collateral declines to zero, without any consideration of recovery or offset from any economic hedges. Accordingly, this disclosure is not an indication of expected loss.

(2) All other assets includes mortgage servicing rights, derivative assets, and other assets (predominantly servicing advances). INVOLVEMENT WITH TAX CREDIT VIES In addition to the unconsolidated VIEs in Table 13.4, we may invest in or provide funding to affordable housing, renewable energy or similar projects that are designed to generate a return primarily through the realization of federal 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 $19.0 billion and $18.7 billion at June 30, 2023, and December 31, 2022, respectively. We also had loans to tax credit VIEs with a carrying value of $2.0 billion at both June 30, 2023, and December 31, 2022. Our maximum exposure to loss for tax credit VIEs at June 30, 2023, and December 31, 2022, was $29.7 billion and $28.0 billion, respectively. Our maximum exposure to loss included total unfunded equity and lending commitments of $8.8 billion and $7.3 billion at June 30, 2023, and December 31, 2022, respectively. See Note 14 (Guarantees and Other Commitments) for additional information about commitments to purchase equity securities. Our affordable housing equity investments qualify for the low-income housing tax credit (LIHTC). For additional information on our LIHTC investments, see Note 16 (Securitizations and Variable Interest Entities) in our 2022 Form 10-K. 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 13.5. 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 13.5 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. Table 13.5: Transactions with Consolidated VIEs Carrying value – asset (liability) (in millions) Total Loans Debt All other Liabilities (2) June 30, 2023 Commercial and industrial loans and leases $ 7,345 4,947 — 204 (136) Other 72 — 71 1 (72) Total consolidated VIEs $ 7,417 4,947 71 205 (208) December 31, 2022 Commercial and industrial loans and leases $ 7,148 4,802 — 190 (129) Other 72 — 71 1 (72) Total consolidated VIEs $ 7,220 4,802 71 191 (201) (1) All other assets includes cash and due from banks, and other assets.

Guarantees [Abstract]
Guarantees and Other Commitments	Note 14: Guarantees and Other Commitments Guarantees are contracts that contingently require us to make payments to a guaranteed party based on an event or a change in an underlying asset, liability, rate or index. For additional descriptions of our guarantees, see Note 17 (Guarantees and Other Commitments) in our 2022 Form 10-K. Table 14.1 shows carrying value and maximum exposure to loss on our guarantees. Table 14.1: Guarantees – Carrying Value and Maximum Exposure to Loss Maximum exposure to loss (in millions) Carrying value of obligation Expires in one year or less Expires after one year through three years Expires after three years through five years Expires after five years Total Non-investment grade June 30, 2023 Standby letters of credit (1) $ 92 14,223 4,480 3,550 12 22,265 7,528 Direct pay letters of credit (1) 11 1,137 2,855 407 5 4,404 1,122 Loans and LHFS sold with recourse (2) 20 361 2,112 3,121 8,351 13,945 11,112 Exchange and clearing house guarantees — 6,204 — — — 6,204 — Other guarantees and indemnifications (3) — 515 — 9 216 740 469 Total guarantees $ 123 22,440 9,447 7,087 8,584 47,558 20,231 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 — 4,623 — — — 4,623 — Other guarantees and indemnifications (3) — 548 1 10 201 760 515 Total guarantees $ 141 21,100 8,507 6,941 9,165 45,713 20,268 (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) Includes indemnifications provided to certain third-party clearing agents. Estimated maximum exposure to loss was $172 million and $157 million with related collateral of $1.7 billion and $1.3 billion as of June 30, 2023, and December 31, 2022, 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 14.1 do not reflect economic hedges or collateral we could use to offset or recover losses we may incur under our guarantee agreements. Accordingly, these amounts are not an indication of expected loss. We believe the carrying value is more representative of our current exposure to loss than maximum exposure to loss. The carrying value represents the fair value of the guarantee, if any, and also includes an ACL for guarantees, if applicable. In determining the ACL for guarantees, we consider the credit risk of the related contingent obligation. For our guarantees in Table 14.1, non-investment grade represents those guarantees on which we have a higher risk of performance under the terms of the guarantee, which is determined based on an external rating or an internal credit grade that is below investment grade. WRITTEN OPTIONS We enter into written foreign currency options and over-the-counter written equity put options that are derivative contracts that have the characteristics of a guarantee. The fair value of written options represents our view of the probability that we will be required to perform under the contract. The fair value of these written options was an asset of $449 million and a liability of $15 million at June 30, 2023, and December 31, 2022, 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 June 30, 2023, the maximum exposure to loss was $31.8 billion, with $29.3 billion expiring in three years or less compared with $23.4 billion and $21.3 billion, respectively, at December 31, 2022. See Note 11 (Derivatives) for additional information regarding written derivative contracts. REPRESENTATIONS OR WARRANTIES We record a liability for mortgage loans that we expect to repurchase pursuant to various representations or warranties. See Note 13 (Securitizations and Variable Interest Entities) for further discussion and related amounts. Additionally, when we sell MSRs, we may provide indemnifications for losses incurred due to material breaches of contractual representations or warranties as well as other recourse arrangements. At June 30, 2023, our liability for these indemnification arrangements was $8 million and the maximum exposure to loss was $650 million, with $609 million expiring in three years or less. MERCHANT PROCESSING SERVICES We provide debit and credit card transaction processing services through payment networks directly for merchants and as a sponsor for merchant processing servicers, including our joint venture with a third party that is accounted for as an equity method investment. In our role as the merchant acquiring bank, we have a potential obligation in connection with payment and delivery disputes between the merchant and the cardholder that are resolved in favor of the cardholder, referred to as a charge-back transaction. We estimate our potential maximum exposure to be the total merchant transaction volume processed in the preceding four months, which is generally the lifecycle for a charge-back transaction. As of June 30, 2023, our potential maximum exposure was approximately $789.5 billion, and related losses, including those from our joint venture entity, were insignificant. GUARANTEES OF SUBSIDIARIES The Parent fully and unconditionally guarantees the payment of principal, interest, and any other amounts that may be due on securities that its 100% owned finance subsidiary, Wells Fargo Finance LLC, may issue. These securities are not guaranteed by any other subsidiary of the Parent. The guaranteed liabilities were $847 million and $948 million at June 30, 2023, and December 31, 2022, respectively. These guarantees rank on parity with all of the Parent’s other unsecured and unsubordinated indebtedness. 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 both June 30, 2023, and December 31, 2022, we had commitments to purchase debt securities of $100 million and commitments to purchase equity securities of $5.0 billion and $3.8 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 14.1 in Other guarantees and indemnifications. We have commitments to enter into resale and securities borrowing agreements as well as repurchase and securities lending agreements with certain counterparties, including central clearing organizations. The amount of our unfunded contractual commitments for resale and securities borrowing agreements was $16.6 billion and $19.9 billion as of June 30, 2023, and December 31, 2022, respectively. The amount of our unfunded contractual commitments for repurchase and securities lending agreements was $2.4 billion and $1.6 billion as of June 30, 2023, and December 31, 2022, 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).

Pledged Assets and Collateral

Pledged Assets and Collateral	6 Months Ended
Pledged Assets and Collateral	Jun. 30, 2023
Transfers and Servicing [Abstract]
Pledged Assets and Collateral	Note 15: Pledged Assets and Collateral Pledged Assets Table 15.1 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 13 (Securitizations and Variable Interest Entities) for additional information on consolidated VIE assets. Table 15.1: Pledged Assets (in millions) Jun 30, Dec 31, Related to trading activities: Off-balance sheet repledged third-party owned debt and equity securities $ 56,044 38,191 Trading debt securities and other 51,534 28,284 Equity securities 1,996 1,477 Total pledged assets related to trading activities 109,574 67,952 Related to non-trading activities: Loans 375,115 344,000 Debt securities: Available-for-sale 66,018 50,538 Held-to-maturity 247,754 17,477 Equity securities 178 141 Total pledged assets related to non-trading activities 689,065 412,156 Related to VIEs: Consolidated VIE assets 5,223 5,064 Loans eligible for repurchase from GNMA securitizations 946 749 Total pledged assets related to VIEs 6,169 5,813 Total pledged assets $ 804,808 485,921 Securities and Other Collateralized Financing Activities We enter into resale and repurchase agreements and securities borrowing and lending agreements (collectively, “securities financing activities”) typically to finance trading positions (including securities and derivatives), acquire securities to cover short trading positions, accommodate customers’ financing needs, and settle other securities obligations. These activities are conducted through our broker-dealer subsidiaries and, to a lesser extent, through other bank entities. Our securities financing activities primarily involve high-quality, liquid securities such as U.S. Treasury securities and government agency securities and, to a lesser extent, less liquid securities, including equity securities, corporate bonds and asset-backed securities. We account for these transactions as collateralized financings in which we typically receive or pledge securities as collateral. We believe these financing transactions generally do not have material credit risk given the collateral provided and the related monitoring processes. We also enter into resale agreements involving collateral other than securities, such as loans, as part of our commercial lending business activities. OFFSETTING OF SECURITIES AND OTHER COLLATERALIZED FINANCING ACTIVITIES Table 15.2 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 15.2, we also have balance sheet netting related to derivatives that is disclosed in Note 11 (Derivatives). Table 15.2: Offsetting – Securities and Other Collateralized Financing Activities (in millions) Jun 30, Dec 31, Assets: Resale and securities borrowing agreements Gross amounts recognized $ 116,017 114,729 Gross amounts offset in consolidated balance sheet (1) (27,246) (24,464) Net amounts in consolidated balance sheet (2) 88,771 90,265 Collateral not recognized in consolidated balance sheet (3) (88,285) (89,592) Net amount (4) $ 486 673 Liabilities: Repurchase and securities lending agreements Gross amounts recognized $ 94,834 55,054 Gross amounts offset in consolidated balance sheet (1) (27,246) (24,464) Net amounts in consolidated balance sheet (5) 67,588 30,590 Collateral pledged but not netted in consolidated balance sheet (6) (67,478) (30,383) Net amount (4) $ 110 207 (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 $66.5 billion and $68.0 billion classified on our consolidated balance sheet in federal funds sold and securities purchased under resale agreements at June 30, 2023, and December 31, 2022, respectively. Also includes $22.3 billion and $22.3 billion classified on our consolidated balance sheet in loans at June 30, 2023, and December 31, 2022, respectively. (3) Represents the fair value of collateral we have received under enforceable MRAs or MSLAs, limited in the table above to the amount of the recognized asset due from each counterparty. At June 30, 2023, and December 31, 2022, we have received total collateral with a fair value of $140.0 billion and $136.6 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 $83.4 billion and $59.1 billion at June 30, 2023, and December 31, 2022, 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 June 30, 2023, and December 31, 2022, we have pledged total collateral with a fair value of $97.1 billion and $56.3 billion, respectively, substantially all of which may be sold or repledged by the counterparty. REPURCHASE AND SECURITIES LENDING AGREEMENTS Securities sold under repurchase agreements and securities lending arrangements are effectively short-term collateralized borrowings. In these transactions, we receive cash in exchange for transferring securities as collateral and recognize an obligation to reacquire the securities for cash at the transaction’s maturity. These types of transactions create risks, including (1) the counterparty may fail to return the securities at maturity, (2) the fair value of the securities transferred may decline below the amount of our obligation to reacquire the securities, and therefore create an obligation for us to pledge additional amounts, and (3) the counterparty may accelerate the maturity on demand, requiring us to reacquire the security prior to contractual maturity. We attempt to mitigate these risks in various ways. Our collateral primarily consists of highly liquid securities. In addition, we underwrite and monitor the financial strength of our counterparties, monitor the fair value of collateral pledged relative to contractually required repurchase amounts, and monitor that our collateral is properly returned through the clearing and settlement process in advance of our cash repayment. Table 15.3 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. Table 15.3: Gross Obligations by Underlying Collateral Type (in millions) Jun 30, Dec 31, Repurchase agreements: Securities of U.S. Treasury and federal agencies $ 34,235 27,857 Securities of U.S. States and political subdivisions 79 83 Federal agency mortgage-backed securities 42,968 8,386 Non-agency mortgage-backed securities 694 682 Corporate debt securities 6,617 6,541 Asset-backed securities 2,633 1,529 Equity securities 433 711 Other 245 300 Total repurchases 87,904 46,089 Securities lending arrangements: Securities of U.S. Treasury and federal agencies 284 278 Federal agency mortgage-backed securities 62 58 Corporate debt securities 210 206 Equity securities (1) 6,342 8,356 Other 32 67 Total securities lending 6,930 8,965 Total repurchases and securities lending $ 94,834 55,054 (1) Equity securities are generally exchange traded and represent collateral received from third parties that has been repledged. We received the collateral through either margin lending agreements or contemporaneous securities borrowing transactions with other counterparties. Table 15.4 provides the contractual maturities of our gross obligations under repurchase and securities lending agreements.

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 16: 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. 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.

Adjustments are included in Corporate, Commercial Banking, and Corporate and Investment Banking and are eliminated to reconcile to the Company’s consolidated financial results. (2) These revenue types are related to financial assets and liabilities, including loans, leases, securities and derivatives, with additional details included in other footnotes to our financial statements. (3) We earned trailing commissions of $227 million and $454 million for the second quarter and first half of 2023, respectively, and $245 million and $516 million for the second quarter and first half of 2022, respectively. (4) The cost of credit card rewards and rebates of $628 million and $1.2 billion for the second quarter and first half of 2023, respectively, and $552 million and $1.0 billion for the second quarter and first half of 2022, respectively, are presented net against the related revenue. (5) In first quarter 2023, we adopted ASU 2018-12 – Financial Services – Insurance (Topic 944): Targeted Improvements to the Accounting for Long-Duration Contracts. For additional information, see Note 1 (Summary of Significant Accounting Policies). Expenses OPERATING LOSSES Operating losses consist of litigation, regulatory matters, customer remediation activities, and losses from other business activities, such as fraud losses. Operating losses may have significant variability given the inherent and unpredictable nature of litigation, regulatory, and customer remediation matters. The timing and determination of the amount of any associated losses for these matters depends on a variety of factors, some of which are outside of our control. Our operating losses were $232 million and $499 million for the second quarter and first half of 2023, respectively, compared with $576 million and $1.2 billion in the same periods a year ago. See Note 10 (Legal Actions) for additional information on accruals for legal actions. OTHER EXPENSES Regulatory Charges and Assessments expense, which is included in other noninterest expense, was $301 million and $572 million in the second quarter and first half of 2023, respectively, compared with $208 million and $433 million in the same periods a year ago, and primarily consisted of Federal Deposit Insurance Corporation (FDIC) deposit assessment expense. In May 2023, the FDIC proposed a rule to recover by special assessment losses to the FDIC deposit insurance fund as a result of recent bank failures. Under the proposed rule, the FDIC would collect a special assessment based on a calculation using an insured depository institution’s estimated amount of uninsured deposits. As currently proposed, the amount of our special assessment may be up to $1.8 billion (pre-tax), and we expect to expense the entire amount upon the FDIC’s finalization of the rule. The proposed rule may be changed prior to finalization and any changes may affect the timing or amount of the special assessment.

Regulatory Capital Requirements and Other Restrictions [Abstract]
Regulatory Capital Requirements and Other Restrictions	Note 21: 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 21.1 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 June 30, 2023, the Bank and our other insured depository institutions were considered well-capitalized under the requirements of the Federal Deposit Insurance Act.

(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 June 30, 2023, 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. Additionally, federal laws and regulations limit, and regulators can impose additional limitations on, the dividends that a national bank may pay. Our nonbank subsidiaries are also limited by certain federal and state statutory provisions and regulations covering the amount of dividends that may be paid in any given year. In addition, 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. For additional information on loan and dividend restrictions, see Note 25 (Regulatory Capital Requirements and Other Restrictions) in our 2022 Form 10-K.

Summary of Significant Accounting Policies (Policies)	Jun. 30, 2023
Significant Accounting Policies [Line Items]
Business Description and Basis of Presentation	Wells Fargo & Company is a diversified financial services company. We provide banking, investment and mortgage products and services, as well as consumer and commercial finance, through banking locations and offices, the internet and other distribution channels to individuals, businesses and institutions in all 50 states, the District of Columbia, and in countries outside the U.S. When we refer to “Wells Fargo,” “the Company,” “we,” “our” or “us,” we mean Wells Fargo & Company and Subsidiaries (consolidated). Wells Fargo & Company (the Parent) is a financial holding company and a bank holding company. We also hold a majority interest in a real estate investment trust, which has publicly traded preferred stock outstanding. Our accounting and reporting policies conform with U.S. generally accepted accounting principles (GAAP) and practices in the financial services industry. For discussion of our significant accounting policies, see Note 1 (Summary of Significant Accounting Policies) in our Annual Report on Form 10-K for the year ended December 31, 2022 (2022 Form 10-K). There were no material changes to these policies in the first half of 2023.
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 13 (Securitizations and Variable Interest Entities)); • valuations of financial instruments (Note 12 (Fair Values of Assets and Liabilities)); • liabilities for contingent litigation losses (Note 10 (Legal Actions)); • income taxes; and • goodwill impairment (Note 7 (Intangible Assets and Other Assets)). Actual results could differ from those estimates. These unaudited interim financial statements reflect all adjustments that are, in the opinion of management, necessary for a fair statement of the results for the periods presented. These adjustments are of a normal recurring nature, unless otherwise disclosed in this Form 10-Q. The results of operations in the interim financial statements do not necessarily indicate the results that may be expected for the full year. The interim financial information should be read in conjunction with our 2022 Form 10-K.
Accounting Standards Adopted in 2023	Accounting Standards Adopted in 2023 In 2023, we adopted the following new accounting guidance: • Accounting Standards Update (ASU) 2022-02, Financial Instruments – Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures • ASU 2022-01, Derivatives and Hedging (Topic 815): Fair Value Hedging – Portfolio Layer Method • ASU 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers • ASU 2018-12, Financial Services – Insurance (Topic 944): Targeted Improvements to the Accounting for Long-Duration Contracts and subsequent related updates
Subsequent Events	Subsequent Events We have evaluated the effects of events that have occurred subsequent to June 30, 2023, and except as disclosed in Note 9 (Preferred Stock), there have been no material events that would require recognition in our second quarter 2023 consolidated financial statements or disclosure in the Notes to the consolidated financial statements.
Accounting Standards Update 2022-02 [Member]
Significant Accounting Policies [Line Items]
Accounting Standards Adopted in 2023	ASU 2022-02 eliminates the accounting and reporting for troubled debt restructurings (TDRs) by creditors and introduces new required disclosures for loan modifications made to borrowers experiencing financial difficulty. The new required disclosures include information about modifications granted to borrowers experiencing financial difficulty in the form of principal forgiveness, interest rate reductions, other-than-insignificant payment delays, term extensions, or a combination of these modifications. The ASU also requires new disclosures for the financial effects of these modifications and for loan performance in the twelve months following the modification. The Update also amends the guidance for vintage disclosures to require disclosure of current period gross charge-offs by year of origination. See Note 5 (Loans and Related Allowance for Credit Losses) for additional information related to the new disclosures for loan modifications to borrowers experiencing financial difficulty and for gross charge-offs by year of origination, which are provided on a prospective basis. The Update eliminates the requirement to use a discounted cash flow (DCF) approach to measure the allowance for credit losses (ACL) for TDRs and instead allows for the use of a current expected credit loss approach for all loans. Under a current expected credit loss approach, the impact of loan modifications and the subsequent performance of modified loans, including defaults, is reflected in the historical loss data used to calculate expected lifetime credit losses. Upon adoption on January 1, 2023, we discontinued utilizing a DCF approach to measure credit impairment for consumer loans and certain commercial loans previously modified in a TDR and we removed the interest concession component recognized in the ACL. We elected to apply the modified-retrospective transition approach method, resulting in a cumulative effect adjustment to retained earnings upon adoption, which reflects the difference between the pre-modification and post-modification effective interest rates that would have been recognized over the remaining life of the loans as interest income. Upon adoption, we recognized a decrease in our ACL of $429 million, pre-tax, and an increase to our retained earnings of $323 million, after tax. We continue to use a DCF approach for certain non-accruing, non-collateral dependent commercial loans.
Accounting Standards Update 2022-01 [Member]
Significant Accounting Policies [Line Items]
Accounting Standards Adopted in 2023	ASU 2022-01 establishes the portfolio layer method, which expands an entity's ability to achieve fair value hedge accounting for interest rate risk hedges of closed portfolios of financial assets. The Update also provides guidance on the accounting for hedged item basis adjustments under the portfolio layer method. We adopted ASU 2022-01 on January 1, 2023 on a prospective basis. No cumulative effect adjustment to the opening balance of stockholders’ equity was required upon adoption, as impacts to us were reflected prospectively. The portfolio layer method improves our ability to use derivatives to hedge interest rate risk exposures associated with portfolios of financial assets, such as fixed-rate available-for-sale (AFS) debt securities and loans. The Update allows us to hedge a larger proportion of these portfolios by expanding the number and type of derivatives permitted as eligible hedges, as well as by increasing the scope of eligible hedged items to include both prepayable and nonprepayable assets. Unlike other fair value hedging relationships where basis adjustments adjust the carrying amount of the individual hedged item, basis adjustments related to active portfolio layer method hedges are maintained at a portfolio level and not allocated to the individual assets in the portfolio. Upon adoption, any election to designate portfolio layer method hedges is applied prospectively. Additionally, the Update permits a one-time reclassification of debt securities from held-to-maturity (HTM) to AFS classification as long as the securities are designated in a portfolio layer method hedge no later than 30 days after the adoption date. 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 HTM to AFS and designated interest rate swaps with notional amounts of $20.1 billion as fair value hedges using the portfolio layer method. The transfer of debt securities was recorded at fair value and resulted in approximately $566 million of unrealized losses associated with AFS debt securities being recorded to other comprehensive income, net of deferred taxes.
Accounting Standards Update 2021-08 [Member]
Significant Accounting Policies [Line Items]
Accounting Standards Adopted in 2023	ASU 2021-08 amends Accounting Standards Codification (ASC) 805 – Business Combinations to require entities to recognize and measure contract assets and contract liabilities in a business combination in accordance with ASC 606 – Revenue Recognition. Prior to ASU 2021-08, there was diversity in practice related to recognition treatment, and acquirers generally measured such items at acquisition date fair value. We adopted this Update prospectively on January 1, 2023. This Update did not have a material impact to our consolidated financial statements.
Accounting Standards Update 2018-12 Retrospective [Member]
Significant Accounting Policies [Line Items]
Accounting Standards Adopted in 2023	ASU 2018-12 changes the accounting for long-duration insurance contracts or contract features that provide benefits to the policyholder in addition to the policyholder’s account value. These features, which the ASU defines as market risk benefits, protect the policyholder to some degree from capital markets risk and expose the insurer or reinsurer to that risk. The ASU requires all market risk benefits to be measured at fair value through earnings with changes in fair value attributable to our own credit risk recognized in other comprehensive income. We reinsure certain variable annuity products for a limited number of insurance clients with guaranteed minimum benefits which are accounted for as market risk benefits under the ASU. Our reinsurance business is no longer entering into new contracts. We utilize a discounted cash flow model to value our market risk benefits. Market risk benefits are level 3 fair value liabilities because they are valued using significant unobservable inputs. The fair value of our market risk benefits is sensitive to changes in fixed income and equity markets, as well as policyholder behavior (e.g., withdrawals, lapses, utilization rate) and changes in mortality assumptions. Beginning first quarter 2023, we use derivative instruments, where feasible, to economically hedge the interest rate and equity markets volatility. The fair value of market risk benefits is measured at the contract level and is recognized in accrued expenses and other liabilities. We recognize changes in fair value for our market risk benefits, excluding the change in fair value related to our own credit risk, in noninterest income along with the changes in fair value of economic hedges. Changes in fair value attributable to our own credit risk are recorded in other comprehensive income. Upon adoption on January 1, 2023, as required under the ASU, we implemented the accounting changes for market risk benefits retrospectively, to the earliest period presented, which resulted in an after-tax cumulative effect adjustment to reduce retained earnings and accumulated other comprehensive income by $176 million and $44 million, respectively, as of January 1, 2022. The ASU also requires more frequent updates for insurance assumptions, mandates the use of a standardized discount rate for traditional long-duration contracts, and simplifies the amortization of deferred acquisition costs. The accounting changes for the liability of future policyholder benefits for traditional long-duration contracts (included in accrued expenses and other liabilities) and deferred acquisition costs (included in other assets) did not have a material impact upon adoption. Table 1.1 presents the impact of adoption to prior period financial statement line items within our consolidated statement of income and consolidated balance sheet for the three and six months ended June 30, 2022, and as of December 31, 2022. These adjustments are also reflected in our consolidated statement of changes in equity and consolidated statement of cash flows.

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.

Commercial Loan Categories by Risk Categories and Vintage	Table 5.7 provides the outstanding balances of our commercial loan portfolio by risk category and credit quality information by origination year for term loans. Revolving loans may convert to term loans as a result of a contractual provision in the original loan agreement or if modified for a borrower experiencing financial difficulty. At June 30, 2023, we had $526.6 billion and $29.0 billion of pass and criticized commercial loans, respectively. Gross charge-offs by loan class are included in the following table for the six months ended June 30, 2023, which we monitor as part of our credit risk management practices; however, charge-offs are not a primary credit quality indicator for our loan portfolio.

Credit Quality Indicators for Residential Mortgage Loans by Vintage	Table 5.9 provides the outstanding balances of our residential mortgage loans by our primary credit quality indicators. 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.

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 $132 million for the quarter ended June 30, 2022, and $250 million for the first half of 2022. (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 5.18 summarizes permanent modification TDRs that defaulted during the period presented 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.

Net gains (losses) included in other comprehensive income for AFS debt securities were $(3) million and $(19) million for the second quarter and first half of 2023, respectively, and $(6) million and $(27) million for the second quarter and first half of 2022, respectively. Net gains (losses) included in other comprehensive income for other liabilities were $5 million for both the second quarter and first half of 2023, and $87 million and $101 million for the second quarter and first half of 2022, respectively. (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) All amounts represent net unrealized gains (losses) related to assets and liabilities held at period end included in net income except for AFS debt securities and other liabilities which also included net unrealized gains (losses) related to assets and liabilities held at period end in other comprehensive income. Net unrealized gains (losses) included in other comprehensive income for AFS debt securities were $(2) million and $(17) million for the second quarter and first half of 2023, respectively, and $0 for both the second quarter and first half of 2022. Net unrealized gains (losses) included in other comprehensive income for other liabilities were $5 million for both the second quarter and first half of 2023, and $87 million and $101 million for the second quarter and first half of 2022, 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. (8) For additional information on the changes in mortgage servicing rights, see Note 6 (Mortgage Banking Activities). (9) Included in mortgage banking income, net gains from trading and securities, and other noninterest income on our consolidated statement of income. (10) Included in other noninterest income on our consolidated statement of income.

For additional information, see Note 1 (Summary of Significant Accounting Policies).
Valuation Techniques - Recurring Basis	Table 12.3 provides quantitative information about the valuation techniques and significant unobservable inputs used in the valuation of our Level 3 assets and liabilities measured at fair value on a recurring basis. The significant unobservable inputs for Level 3 assets inherent in the fair values obtained from third-party vendors are not included in the table, as the specific inputs applied are not provided by the vendor (for additional information on vendor-developed valuations, see Note 15 (Fair Values of Assets and Liabilities) in our 2022 Form 10-K). Weighted averages of inputs are calculated using outstanding unpaid principal balance for cash instruments, such as loans and securities, and notional amounts for derivative instruments.

Valuation Techniques - Nonrecurring Basis	Table 12.6 provides quantitative information about the valuation techniques and significant unobservable inputs used in the valuation of our Level 3 assets that are measured at fair value on a nonrecurring basis and determined using an internal model. The table is limited to financial instruments that had nonrecurring fair value adjustments during the periods presented. Weighted averages of inputs are calculated using outstanding unpaid principal balance for cash instruments, such as loans, and carrying value prior to the nonrecurring fair value measurement for nonmarketable equity securities and private equity and venture capital investments in consolidated portfolio companies.

Fair Value Estimates for Financial Instruments	Table 12.9 presents a summary of fair value estimates for financial instruments that are not carried at fair value on a recurring basis. Some financial instruments are excluded from the scope of this table, such as certain insurance contracts, certain nonmarketable equity securities, and leases. This table also excludes assets and liabilities that are not financial instruments such as the value of the long-term relationships with our deposit, credit card and trust customers, MSRs, premises and equipment, goodwill and deferred taxes. Loan commitments, standby letters of credit and commercial and similar letters of credit are not included in Table 12.9. A reasonable estimate of the fair value of these instruments is the carrying value of deferred fees plus the allowance for unfunded credit commitments, which totaled $622 million and $737 million at June 30, 2023, and December 31, 2022, respectively. The total of the fair value calculations presented does not represent, and should not be construed to represent, the underlying fair value of the Company.

Securitizations and Variable Interest Entities [Abstract]
Transfers With Continuing Involvement	Table 13.1 presents information about transfers of assets during the periods presented for which we recorded the transfers as sales and have continuing involvement with the transferred assets. In connection with these transfers, we received proceeds and recorded servicing assets and securities. Each of these interests are initially measured at fair value. Servicing rights are classified as Level 3 measurements, and generally securities are classified as Level 2. The majority of our transfers relate to residential mortgage securitizations with the GSEs or GNMA and generally result 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 13.1: Transfers with Continuing Involvement 2023 2022 (in millions) Residential mortgages Commercial mortgages Residential mortgages Commercial mortgages Quarter ended June 30, Assets sold $ 3,917 1,800 23,817 4,345 Proceeds from transfer (1) 3,917 1,823 23,817 4,411 Net gains (losses) on sale — 23 — 66 Continuing involvement (2): Servicing rights recognized $ 46 16 313 41 Securities recognized (3) — 22 475 33 Six months ended June 30, Assets sold $ 8,378 3,299 49,991 8,378 Proceeds from transfer (1) 8,378 3,363 50,043 8,508 Net gains (losses) on sale — 64 52 130 Continuing involvement (2): Servicing rights recognized $ 93 34 640 70 Securities recognized (3) — 48 2,062 137 (1) Represents cash proceeds and the fair value of non-cash beneficial interests recognized at securitization settlement. (2) Represents assets or liabilities recognized at securitization settlement date related to our continuing involvement in the transferred assets. (3) Represents debt securities obtained at securitization settlement held for investment purposes that are classified as available-for-sale or held-to-maturity. In 2022, these predominantly related 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 $1.8 billion and $3.7 billion during the second quarter and first half of 2023, respectively, and $3.6 billion and $10.3 billion during the second quarter and first half of 2022, respectively.
Residential MSRs - Assumptions at Securitization Date	Table 13.2 presents the key weighted-average assumptions we used to initially measure residential MSRs recognized during the periods presented. Table 13.2: Residential MSRs – Assumptions at Securitization Date 2023 2022 Quarter ended June 30, Prepayment rate (1) 16.4 % 10.9 Discount rate 9.4 8.0 Cost to service ($ per loan) $ 176 122 Six months ended June 30, Prepayment rate (1) 17.5 % 11.0 Discount rate 9.6 7.5 Cost to service ($ per loan) $ 185 117 (1) Includes a blend of prepayment speeds and expected defaults. Prepayment speeds are influenced by mortgage interest rates as well as our estimation of drivers of borrower behavior.
Sold or Securitized Loans Serviced for Others	Table 13.3 presents information about loans that we 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 13.3 excludes mortgage loans sold to and held or securitized by GSEs or GNMA of $637.0 billion and $704.5 billion at June 30, 2023, and December 31, 2022, respectively. Delinquent loans and foreclosed assets related to loans sold to and held or securitized by GSEs or GNMA were $3.4 billion and $4.6 billion at June 30, 2023, and December 31, 2022, respectively.

Unconsolidated VIEs	Table 13.4 provides a summary of our exposure to the unconsolidated VIEs described above, which includes investments in securities, loans, guarantees, liquidity agreements, commitments and certain derivatives. We exclude certain transactions with unconsolidated VIEs when our continuing involvement is temporary or administrative in nature or insignificant in size. In Table 13.4, “Total VIE assets” represents the remaining principal balance of assets held by unconsolidated VIEs using the most current information available. “Carrying value” is the amount in our consolidated balance sheet related to our involvement with the unconsolidated VIEs. “Maximum exposure to loss” is determined as the carrying value of our investment in the VIEs excluding the unconditional repurchase options that have not been exercised, plus the remaining undrawn liquidity and lending commitments, the notional amount of net written derivative contracts, and generally the notional amount of, or stressed loss estimate for, other commitments and guarantees. Debt, guarantees and other commitments include amounts related to lending arrangements, liquidity agreements, and certain loss sharing obligations associated with loans originated, sold, and serviced under certain GSE programs. “Maximum exposure to loss” represents estimated loss that would be incurred under severe, hypothetical circumstances, for which we believe the possibility is extremely remote, such as where the value of our interests and any associated collateral declines to zero, without any consideration of recovery or offset from any economic hedges. Accordingly, this disclosure is not an indication of expected loss.

Transactions with Consolidated VIEs	Table 13.5 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)	Jun. 30, 2023
Transfers and Servicing [Abstract]
Pledged Assets	Table 15.1 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 13 (Securitizations and Variable Interest Entities) for additional information on consolidated VIE assets.

Offsetting - Securities and Other Collateralized Financing Activities	Table 15.2 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 15.2, we also have balance sheet netting related to derivatives that is disclosed in Note 11 (Derivatives).

Regulatory Capital Requirements and Other Restrictions [Abstract]
Regulatory Capital Information	Table 21.1 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 June 30, 2023, the Bank and our other insured depository institutions were considered well-capitalized under the requirements of the Federal Deposit Insurance Act.
