Significant Accounting Policies [Line Items]

Business Description and Basis of Presentation

Wells Fargo & Company is a diversified financial services company. We provide banking, trust and investments, mortgage banking, investment banking, retail banking, brokerage, and consumer and commercial finance through banking locations, the internet and other distribution channels to consumers, businesses and institutions in all 50 states, the District of Columbia, and in foreign countries. When we refer to “Wells Fargo,” “the Company,” “we,” “our” or “us,” we mean Wells Fargo & Company and Subsidiaries (consolidated). Wells Fargo & Company (the Parent) is a financial holding company and a bank holding company. We also hold a majority interest in a real estate investment trust, which has publicly traded preferred stock outstanding.Our accounting and reporting policies conform with U.S. generally accepted accounting principles (GAAP) and practices in the financial services industry. For discussion of our significant accounting policies, see Note 1 (Summary of Significant Accounting Policies) in our Annual Report on Form 10-K for the year ended December 31, 2019 (2019 Form 10-K).

Use of Estimates

To prepare the financial statements in conformity with GAAP, management must make estimates based on assumptions about future economic and market conditions (for example, unemployment, market liquidity, real estate prices, etc.) that affect the reported amounts of assets and liabilities at the date of the financial statements, income and expenses during the reporting period and the related disclosures. Although our estimates contemplate current conditions and how we expect them to change in the future, it is reasonably possible that actual conditions could be worse than anticipated in those estimates, which could materially affect our results of operations and financial condition. Management has made significant estimates in several areas, including:

•allowance for credit losses (Note 6 (Loans and Related Allowance for Credit Losses);

•valuations of residential mortgage servicing rights (MSRs) (Note 10 (Securitizations and Variable Interest Entities) and Note 11 (Mortgage Banking Activities));

•valuations of financial instruments (Note 15 (Derivatives) and Note 16 (Fair Values of Assets and Liabilities));

•liabilities for contingent litigation losses (Note 14 (Legal Actions)); and

•income taxes.

Actual results could differ from those estimates.

Comparability of Prior Year Financial Data

These unaudited interim financial statements reflect all adjustments that are, in the opinion of management, necessary for a fair statement of the results for the periods presented. These adjustments are of a normal recurring nature, unless otherwise disclosed in this Form 10-Q. The results of operations in the interim financial statements do not necessarily indicate the results that may be expected for the full year. The interim financial information should be read in conjunction with our 2019 Form 10-K.

Interest Income and Gain (Loss) Recognition

INTEREST INCOME AND GAIN/LOSS RECOGNITION Unamortized premiums and discounts are recognized in interest income over the contractual life of the security using the effective interest method, except for purchased callable debt securities carried at a premium. For purchased callable debt securities carried at a premium, the premium is amortized into interest income to the earliest call date using the effective interest method. As principal repayments are received on securities (e.g., mortgage-backed securities (MBS)), a proportionate amount of the related premium or discount is recognized in income so that the effective interest rate on the remaining portion of the security continues unchanged.

We recognize realized gains and losses on the sale of debt securities in net gains (losses) on debt securities within noninterest income using the specific identification method.

Credit Loss, Financial Instrument

IMPAIRMENT AND CREDIT LOSSES Unrealized losses of AFS debt securities are driven by a number of factors, including changes in interest rates and credit spreads which impact most types of debt securities with additional considerations for certain types of debt securities:

•Debt securities of U.S. Treasury and federal agencies, including federal agency MBS, are not impacted by credit movements given the explicit or implicit guarantees provided by the U.S. government.

•Debt securities of U.S. states and political subdivisions are most impacted by changes in the relationship between municipal and term funding credit curves rather than by changes in the credit quality of the underlying securities.

•Structured securities, such as MBS and collateralized loan obligations (CLO), are also impacted by changes in projected collateral losses of assets underlying the security.

    For debt securities where fair value is less than amortized cost basis, we recognize impairment in earnings if we have the intent to sell the security or if it is more likely than not that we will be required to sell the security before recovery of its amortized cost basis. Impairment is recognized equal to the entire difference between the amortized cost basis and the fair value of the security and is classified as net gains (losses) from debt securities within noninterest income. Following the recognition of impairment, the security’s new amortized cost basis is the previous basis less impairment.

    For debt securities where fair value is less than amortized cost basis where we did not recognize impairment in earnings, we set up an allowance for credit losses as of the balance sheet date. See “Allowance for Credit Losses” section in this Note.

TRANSFERS BETWEEN CATEGORIES OF DEBT SECURITIES AFS debt securities transferred to the HTM classification are recorded at fair value and the unrealized gains or losses resulting from the transfer of these securities continue to be reported in cumulative OCI. The cumulative OCI balance is amortized into earnings over the same period as the unamortized premiums and discounts using the effective interest method. Any allowance for credit losses previously recorded under the AFS model on securities transferred to HTM is reversed and an allowance for credit losses is subsequently recorded under the HTM debt security model.

NONACCRUAL AND PAST DUE, AND CHARGE-OFF POLICIES We generally place debt securities on nonaccrual status using factors similar to those described for loans. When we place a debt security on nonaccrual status, we reverse the accrued unpaid interest receivable against interest income and suspend the amortization of premiums and accretion of discounts. If the ultimate collectability of the principal is in doubt on a nonaccrual debt security, any cash collected is first applied to reduce the security’s amortized cost basis to zero, followed by recovery of amounts previously charged off, and subsequently to interest income. Generally, we return a debt security to accrual status when all delinquent interest and principal become current under the contractual terms of the security and collectability of remaining principal and interest is no longer doubtful.

    Our debt securities are considered past due when contractually required principal or interest payments have not been made on the due dates.

    Our charge-off policy for debt securities are similar to those described for loans. Subsequent to charge-off, the debt security will be designated as nonaccrual and follow the process described above for any cash received.

Allowance for Credit Losses

The ACL is management’s estimate of the current expected credit losses in the loan portfolio and unfunded credit commitments, at the balance sheet date, excluding loans and unfunded credit commitments carried at fair value or held for sale. Additionally, we maintain an ACL on AFS and HTM debt securities, other financing receivables measured at amortized cost, and other off-balance sheet credit exposures. While we attribute portions of the allowance to specific financial asset classes (loan and debt security portfolios), loan portfolio segments (commercial and consumer) or major security type, the entire ACL is available to absorb credit losses of the Company.

Our ACL process involves procedures to appropriately consider the unique risk characteristics of our financial asset classes, portfolio segments, and major security types. For each loan portfolio segment and each major HTM debt security type, losses are estimated collectively for groups of loans or securities with similar risk characteristics. For loans and securities that do not share similar risk characteristics with other financial assets, the losses are estimated individually, which primarily includes our impaired large commercial loans and non-accruing HTM debt securities. For AFS debt securities, losses are estimated at the tax-lot level.

Our ACL amounts are influenced by a variety of factors, including changes in loan and debt security volumes, portfolio credit quality, and general economic conditions. General economic conditions are forecasted using economic variables which will create volatility as those variables change over time. See Table 1.2 for key economic variables used for our loan portfolios.

Table 1.2: Key Economic Variables

Loan Portfolio	Key economic variables
Total commercial	• Gross domestic product • Commercial real estate asset prices, where applicable • Unemployment rate • Corporate investment-grade bond spreads
Real estate 1-4 family mortgage	• Home price index • Unemployment rate
Other consumer (including credit card, automobile, and other revolving credit and installment)	• Unemployment rate

    Our approach for estimating expected life-time credit losses for loans and debt securities includes the following key components:

•An initial loss forecast period of one year for all portfolio segments and classes of financing receivables and off-balance-sheet credit exposures. This period reflects management’s expectation of losses based on forward-looking economic scenarios over that time.

•A historical loss forecast period covering the remaining contractual term, adjusted for expected prepayments and certain expected extensions, renewals, or modifications, by portfolio segment and class of financing receivables based on the changes in key historical economic variables during representative historical expansionary and recessionary periods.

•A reversion period of up to two years to connect the losses estimated for our initial loss forecast period to the period of our historical loss forecast based on economic conditions at the measurement date. Our reversion methodology considers the type of portfolio, point in the credit cycle, expected length of recessions and recoveries, as well as other relevant factors.

•Utilization of discounted cash flow (DCF) methods to measure credit impairment for loans modified in a troubled debt restructuring, unless they are collateral dependent and measured at the fair value of the collateral. The DCF methods obtain estimated life-time credit losses using the initial and historical mean loss forecast periods described above.

•For AFS debt securities and certain beneficial interests classified as HTM, we utilize the DCF methods to measure the ACL, which incorporate expected credit losses using the conceptual components described above. The ACL on AFS debt securities is subject to a limitation based on the fair value of the debt securities (fair value floor).

The ACL for financial assets held at amortized cost and AFS debt securities will be reversible with immediate recognition of recovery in earnings if credit improves. The ACL for financial assets held at amortized cost is a valuation account that is deducted from, or added to, the amortized cost basis of the financial assets to present the net amount expected to be collected, which can include a negative allowance limited to the cumulative amounts previously charged off. For financial assets with an ACL estimated using DCF methods, changes in the ACL due to the passage of time are recorded in interest income. The ACL for AFS debt securities reflects the amount of unrealized loss related to expected credit losses, limited by the amount that fair value is less than the amortized cost basis, and cannot have an associated negative allowance.

For certain financial assets, such as residential real estate loans guaranteed by the Government National Mortgage Association (GNMA), an agency of the federal government, U. S. Treasury and Agency mortgage backed debt securities, as well as certain sovereign debt securities, the Company has not recognized an ACL as our expectation of nonpayment of the

amortized cost basis, based on historical losses, adjusted for current conditions and reasonable and supportable forecasts, is zero.

A financial asset is collateral-dependent when the borrower is experiencing financial difficulty and repayment is expected to be provided substantially through the sale or operation of the collateral. When a collateral-dependent financial asset is probable of foreclosure, we will measure the ACL based on the fair value of the collateral. If we intend to sell the underlying collateral, we will measure the ACL based on the collateral’s net realizable value (fair value of collateral, less estimated costs to sell). In most situations, based on our charge-off policies, we will immediately write-down the financial asset to the fair value of the collateral or net realizable value. For consumer loans, collateral-dependent financial assets may have collateral in the form of residential real estate, automobiles or other personal assets. For commercial loans, collateral-dependent financial assets may have collateral in the form of commercial real estate or other business assets.

We do not generally record an ACL for accrued interest receivables because uncollectible accrued interest is reversed through interest income in a timely manner in line with our non-accrual and past due policies for loans and debt securities. For consumer credit card and certain consumer lines of credit, we include an ACL for accrued interest and fees since these loans are not placed on nonaccrual status and written off until the loan is 180 days past due. Accrued interest receivables are included in other assets, except for certain revolving loans, such as credit card loans.

COMMERCIAL LOAN PORTFOLIO SEGMENT ACL METHODOLOGY Generally, commercial loans, which include net investments in lease financing, are assessed for estimated losses by grading each loan using various risk factors as identified through periodic reviews. Our estimation approach for the commercial portfolio reflects the estimated probability of default in accordance with the borrower’s financial strength and the severity of loss in the event of default, considering the quality of any underlying collateral. Probability of default and severity at the time of default are statistically derived through historical observations of default and losses after default within each credit risk rating. These estimates are adjusted as appropriate based on additional analysis of long-term average loss experience compared with previously forecasted losses, external loss data or other risks identified from current economic conditions and credit quality trends. The estimated probability of default and severity at the time of default are applied to loan equivalent exposures to estimate losses for unfunded credit commitments.

CONSUMER LOAN PORTFOLIO SEGMENT ACL METHODOLOGY For consumer loans, we determine the allowance at the individual loan level. When developing historical loss experience, we pool loans, generally by product types with similar risk characteristics, such as residential real estate mortgages and credit cards. As appropriate and to achieve greater accuracy, we may further stratify selected portfolios by sub-product, origination channel,

vintage, loss type, geographic location and other predictive characteristics. We use pooled loan data such as historic delinquency and default and loss severity in the development of our consumer loan models, in addition to home price trends, unemployment trends, and other economic variables that may influence the frequency and severity of losses in the consumer portfolio.

AFS PORTFOLIO ACL METHODOLOGY We develop our ACL estimate for AFS debt securities by utilizing a security-level multi-scenario, probability-weighted discounted cash flow model based on a combination of past events, current conditions, as well as reasonable and supportable forecasts. The projected cash flows are discounted at the security’s effective interest rate, except for certain variable rate securities which are discounted using projections of future changes in interest rates, prepayable securities which are adjusted for estimated prepayments, and securities part of a fair value hedge which use hedge-adjusted assumptions. The ACL on an AFS debt security is limited to the difference between its amortized cost basis and fair value (fair value floor) and reversals of the allowance are permitted up to the amount previously recorded.

HTM PORTFOLIO ACL METHODOLOGY For most HTM debt securities, the ACL is measured using an expected loss model, similar to the methodology used for loans. Unlike AFS debt securities, the ACL on an HTM debt security is not limited to the fair value floor.

Certain beneficial interests categorized as HTM debt securities utilize a similar discounted cash flow model as described for AFS debt securities, without the limitation of the fair value floor.

OTHER QUALITATIVE FACTORS  The ACL includes amounts for qualitative factors which may not be adequately reflected in our loss models. These amounts represent management’s judgment of risks in the processes and assumptions used in establishing the ACL. Generally, these amounts are established at a granular level below our loan portfolio segments. We also consider economic environmental factors, modeling assumptions and performance, process risk, and other subjective factors, including industry trends and emerging risk assessments.

OFF-BALANCE SHEET CREDIT EXPOSURES Our off-balance sheet credit exposures include unfunded loan commitments (generally in the form of revolving lines of credit), financial guarantees not accounted for as insurance contracts or derivatives, including standby letters of credit, and other similar instruments. For off-balance sheet credit exposures, we recognize an ACL associated with the unfunded amounts. We do not recognize an ACL for commitments that are unconditionally cancelable at our discretion. Additionally, we recognize an ACL for financial guarantees that create off-balance sheet credit exposure, such as loans sold with credit recourse and factoring guarantees. ACL for off-balance sheet credit exposures are reported as a liability in accrued expenses and other liabilities on our consolidated balance sheet.

OTHER FINANCIAL ASSETS Other financial assets are evaluated for expected credit losses. These other financial assets include accounts receivable for fees, receivables from government-sponsored entities, such as Federal National Mortgage Association (FNMA) and Federal Home Loan Mortgage Corporation (FHLMC), and GNMA, and other accounts receivable from high-credit quality counterparties, such as central clearing

counterparties. Many of these financial assets are generally not expected to have an ACL as there is a zero loss expectation (for example, government guarantee) or no historical credit losses. Some financial assets, such as loans to employees, maintain an ACL that is presented on a net basis with the related amortized cost amounts in other assets on our consolidated balance sheet. Given the nature of these financial assets, provision for credit losses is not recognized separately from the regular income or expense associated with these financial assets.

Securities purchased under resale agreements are generally over-collateralized by securities or cash and are generally short-term in nature. We have elected the practical expedient for these financial assets given collateral maintenance provisions. These provisions require that we monitor the collateral value and customers are required to replenish collateral, if needed. Accordingly, we generally do not maintain an ACL for these financial assets.

PURCHASED CREDIT DETERIORATED FINANCIAL ASSETS Financial assets acquired that are of poor credit quality and with more than an insignificant evidence of credit deterioration since their origination or issuance are PCD assets. PCD assets are recorded at their purchase price plus an ACL estimated at the time of acquisition. Under this approach, there is no provision for credit losses recognized at acquisition; rather, there is a gross-up of the purchase price of the financial asset for the estimate of expected credit losses and a corresponding ACL recorded. Changes in estimates of expected credit losses after acquisition are recognized as provision for credit losses (or reversal of provision for credit losses) in subsequent periods. In general, interest income recognition for PCD financial assets is consistent with interest income recognition for the similar non-PCD financial asset.

CARES Act

Troubled Debt Restructuring and Other Relief Related to COVID-19

On March 25, 2020, the U.S. Senate approved the Coronavirus, Aid, Relief, and Economic Security Act (the CARES Act) providing optional, temporary relief from accounting for certain loan modifications as troubled debt restructurings (TDRs). Under the CARES Act, TDR relief is available to banks for loan modifications related to the adverse effects of Coronavirus Disease 2019 (COVID-19) (COVID-related modifications) granted to borrowers that are current as of December 31, 2019. TDR relief applies to COVID-related modifications made from March 1, 2020, until the earlier of December 31, 2020, or 60 days following the termination of the national emergency declared by the President of the United States. In first quarter 2020, we elected to apply the TDR relief provided by the CARES Act.

On April 7, 2020, federal banking regulators issued the Interagency Statement on Loan Modifications and Reporting for Financial Institutions Working with Customers Affected by the Coronavirus (Revised) (the Interagency Statement). The guidance in the Interagency Statement provides additional TDR relief as it clarifies that it is not necessary to consider the impact of the COVID-19 pandemic on the financial condition of a borrower in connection with a short-term (e.g., six months or less) COVID-related modification provided the borrower is current at the date the modification program is implemented.

For COVID-related modifications in the form of payment deferrals, delinquency status will not advance and loans that were accruing at the time the relief is provided will generally not be placed on nonaccrual status during the deferral period. COVID-related modifications that do not meet the provisions of the

CARES Act or the Interagency Statement will be assessed for TDR classification.

On April 10, 2020, the FASB Staff issued Accounting for Lease Concessions Related to the Effects of the COVID-19 Pandemic, a question and answer guide (the guide). The guide provided an election for leases accounted for under Accounting Standards Codification (ASC) 842, Leases, that were modified due to COVID-19 and met certain criteria in order to not require a new

lease classification test upon modification. In second quarter 2020, we elected to apply the lease modification relief provided by the guide.

Accounting Standards Update 2020-04 [Member]

Significant Accounting Policies [Line Items]

Accounting Standards Adopted in 2020

ASU 2020-04 provides optional, temporary relief to ease the burden of accounting for reference rate reform activities that affect contractual modifications of floating rate financial instruments indexed to interbank offering rates (IBORs) and hedge accounting relationships. Modifications of qualifying contracts are accounted for as the continuation of an existing contract rather than as a new contract. Modifications of qualifying hedging relationships will not require discontinuation of the existing hedge accounting relationships. The application of the relief for qualifying existing hedging relationships may be made on a hedge-by-hedge basis and across multiple reporting periods.

We adopted ASU 2020-04 on April 1, 2020, and the guidance will be followed until the Update terminates on December 31, 2022. This guidance is applied on a prospective basis. The Update did not have a material impact on our consolidated financial statements.

Accounting Standards Update 2018-17 [Member]

Significant Accounting Policies [Line Items]

Accounting Standards Adopted in 2020

ASU 2018-17 updates the guidance used by decision-makers of VIEs. Indirect interests held through related parties in common control arrangements will be considered on a proportional basis for determining whether fees paid to decision-makers and service providers are variable interests. This is consistent with how indirect interests held through related parties under common control are considered for determining whether a reporting entity must consolidate a VIE. The Update did not have a material impact on our consolidated financial statements.

Accounting Standards Update 2018-15 [Member]

Significant Accounting Policies [Line Items]

Accounting Standards Adopted in 2020

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

Accounting Standards Update 2018-13 [Member]

Significant Accounting Policies [Line Items]

Accounting Standards Adopted in 2020

ASU 2018-13 clarifies, eliminates and adds certain fair value measurement disclosure requirements for assets and liabilities, which affects our disclosures in Note 16 (Fair Values of Assets and Liabilities). Although the ASU became effective on January 1, 2020, it permitted early adoption of individual requirements without causing others to be early adopted and, as such, we partially adopted the Update during third quarter 2018 and the remainder of the requirements in first quarter 2020. The Update did not have a material impact on our consolidated financial statements.

Accounting Standards Update 2017-04 [Member]

Significant Accounting Policies [Line Items]

Accounting Standards Adopted in 2020

ASU 2017-04 simplifies the goodwill impairment test by eliminating the requirement to assign the fair value of a reporting unit to all of the assets and liabilities of that unit (including any unrecognized intangible assets) as if the reporting unit had been acquired in a business combination. The Update requires that a goodwill impairment loss is recognized if the fair value of the reporting unit is less than the carrying amount, including goodwill. The goodwill impairment loss is limited to the amount of goodwill allocated to the reporting unit. The guidance did not change the qualitative assessment of goodwill. This guidance is applied on a prospective basis, and accordingly, the Update did not have a material impact on our consolidated financial statements.

Accounting Standards Update 2016-13 [Member]

Significant Accounting Policies [Line Items]

Accounting Standards Adopted in 2020

ASU 2016-13 changes the accounting for the measurement of credit losses on loans and debt securities. For loans and held-to-maturity (HTM) debt securities, the Update requires a current expected credit loss (CECL) measurement to estimate the allowance for credit losses (ACL) for the remaining contractual term, adjusted for prepayments, of the financial asset (including off-balance sheet credit exposures) using historical experience, current conditions, and reasonable and supportable forecasts. Also, the Update eliminates the existing guidance for purchased credit-impaired (PCI) loans, but requires an allowance for purchased financial assets with more than an insignificant deterioration of credit since origination. In addition, the Update modifies the other-than-temporary impairment (OTTI) model for available-for-sale (AFS) debt securities to require an allowance for credit impairment instead of a direct write-down, which allows for reversal of credit impairments in future periods based on improvements in credit. Upon adoption, we recognized an overall decrease in our ACL of approximately $1.3 billion (pre-tax) as a cumulative effect adjustment from a change in accounting policies, which increased our retained earnings and regulatory capital amounts and ratios. Loans previously classified as PCI were automatically transitioned to purchased credit-deteriorated (PCD) classification. We recognized an ACL for these new PCD loans and made a corresponding adjustment to the loan balance, with no impact to net income or transition adjustment to retained earnings. For more information on the impact of CECL by type of financial asset, see Table 1.1 below.

(1)Amounts presented in this table may not equal the sum of its components due to rounding.

(2)Decrease reflecting shorter contractual maturities given limitation to contractual terms.

(3)Impact reflects an increase due to longer contractual terms, offset by expectation of recoveries in collateral value on mortgage loans previously written down significantly below current recovery value.

(4)Increase due to longer contractual terms or indeterminate maturities.

(5)Excludes other financial assets in the scope of CECL that do not have an allowance for credit losses based on the nature of the asset.

The adoption of ASU 2016-13 did not result in a change to accounting policies, except as noted herein. Our accounting policy for the ACL was updated and is now inclusive of loans, debt securities and other financing receivables. Other than the ACL and the elimination of PCI loans, there were no changes to accounting policies for loans as described in the 2019 Form 10-K. For debt securities, other than the policies with respect to the ACL, all of the current accounting policies, including those that changed as a result of CECL adoption, are included below under Debt Securities.

Debt securities [Member]

Significant Accounting Policies [Line Items]

Marketable and Nonmarketable Securities, Policy

Debt Securities

Our investments in debt securities that are not held for trading purposes are classified as either debt securities available-for-sale (AFS) or held-to-maturity (HTM).

    Investments in debt securities for which the Company does not have the positive intent and ability to hold to maturity are classified as AFS. AFS debt securities are measured at fair value, with unrealized gains and losses reported in cumulative other comprehensive income (OCI), net of the allowance for credit losses and applicable income taxes. Investments in debt securities

for which the Company has the positive intent and ability to hold to maturity are classified as HTM. HTM debt securities are measured at amortized cost, net of allowance for credit losses.
