Summary of Significant 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, insurance, trust and investments, mortgage banking, investment banking, retail banking, brokerage, and consumer and commercial finance through banking stores, 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.
	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, 2013 (2013 Form 10-K). There were no material changes to these policies in the first half of 2014. 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 and 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 and purchased credit-impaired (PCI) loans (Note 5 (Loans and Allowance for Credit Losses)), valuations of residential mortgage servicing rights (MSRs) (Note 7 (Securitizations and Variable Interest Entities) and Note 8 (Mortgage Banking Activities)) and financial instruments (Note 13 (Fair Values of Assets and Liabilities)), liability for mortgage loan repurchase losses (Note 8 (Mortgage Banking Activities)) and income taxes. Actual results could differ from those estimates.
	These unaudited interim financial statements reflect all adjustments that are, in the opinion of management, necessary for a fair statement of the results for the periods presented. These adjustments are of a normal recurring nature, unless otherwise disclosed in this Form 10-Q. The results of operations in the interim financial statements do not necessarily indicate the results that may be expected for the full year. The interim financial information should be read in conjunction with our 2013 Form 10-K.
	Accounting for Certain Factored Loan Receivable Arrangements
	The Company determined that certain factoring arrangements previously included within commercial loans, which were recorded with a corresponding obligation in other liabilities, did not qualify as loan purchases under Accounting Standard Codification (ASC) Topic 860 (Transfers and Servicing of Financial Assets) based on interpretations of the specific arrangements. Accordingly, we revised our commercial loan balances for year-end 2012 and each of the quarters in 2013 in order to present the Company's lending trends on a comparable basis over this period. This revision, which resulted in a reduction to total commercial loans and a corresponding decrease to other liabilities, did not impact the Company's consolidated net income or total cash flows. We reduced our commercial loans by $3.5 billion, $3.2 billion, $2.1 billion, $1.6 billion, and $1.2 billion at December 31, September 30, June 30 and March 31, 2013, and December 31, 2012, respectively, which represented less than 1% of total commercial loans and less than 0.5% of our total loan portfolio. We also appropriately revised other affected financial information, including financial guarantees and financial ratios, to reflect this revision.
	Accounting Standards Adopted in 2014
	In first quarter 2014, we adopted the following new accounting guidance:
	Accounting Standards Update (ASU or Update) 2014-04, Receivables – Troubled Debt Restructurings by Creditors (Subtopic 310-40) – Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure;
	ASU 2013-11, Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists; and
	ASU 2013-08, Financial Services – Investment Companies (Topic 946): Amendments to the Scope, Measurement and Disclosure Requirements.
	ASU 2014-04 clarifies the timing of when a creditor is considered to have taken physical possession of residential real estate collateral for a consumer mortgage loan, resulting in the reclassification of the loan receivable to real estate owned. A creditor has taken physical possession of the property when either (1) the creditor obtains legal title through foreclosure, or (2) the borrower transfers all interests in the property to the creditor via a deed in lieu of foreclosure or a similar legal agreement. The Update also requires disclosure of the amount of foreclosed residential real estate property held by the creditor and the recorded investment in residential real estate mortgage loans that are in process of foreclosure. We have included this disclosure through an early adoption of this guidance in first quarter 2014 with prospective application. Our adoption of this guidance did not have a material effect on our consolidated financial statements as this guidance was consistent with our prior practice. See Note 5 (Loans and Allowance for Credit Losses) for the new disclosures.
	ASU 2013-11 eliminates diversity in practice as it provides guidance on financial statement presentation of an unrecognized tax benefit when a net operating loss (NOL) carryforward, a similar tax loss, or a tax credit carryforward exists. We adopted this guidance in first quarter 2014 with prospective application to all unrecognized tax benefits that exist at the effective date. This Update did not have a material effect on our consolidated financial statements.
	ASU 2013-08 amends the scope, measurement and disclosure requirements for investment companies. The Update changes criteria companies use to assess whether an entity is an investment company. In addition, investment companies must measure noncontrolling ownership interests in other investment companies at fair value rather than using the equity method of accounting. This Update also requires new disclosures, including information about changes, if any, in an entity's status as an investment company and information about financial support provided or contractually required to be provided by an investment company to any of its investees. We adopted this guidance in first quarter 2014. The Update did not have a material effect on our consolidated financial statements, as our existing practice complies with the requirements.
	Private Share Repurchases
	From time to time we enter into private forward repurchase transactions with unrelated third parties to complement our open-market common stock repurchase strategies, to allow us to manage our share repurchases in a manner consistent with our capital plans, currently submitted under the 2014 Comprehensive Capital Analysis and Review (CCAR), and to provide an economic benefit to the Company.
	Our payments to the counterparties for these contracts are recorded in permanent equity in the quarter paid and are not subject to re-measurement. The classification of the up-front payments as permanent equity assures that we have appropriate repurchase timing consistent with our 2014 capital plan, which contemplated a fixed dollar amount available per quarter for share repurchases pursuant to Federal Reserve Board (FRB) supervisory guidance. In return, the counterparty agrees to deliver a variable number of shares based on a per share discount to the volume-weighted average stock price over the contract period. There are no scenarios where the contracts would not either physically settle in shares or allow us to choose the settlement method. Our total number of outstanding shares of common stock is not reduced until settlement of the private share repurchase contract.
	In June 2014, we entered into a private forward repurchase contract and paid $1.0 billion to an unrelated third party. This contract settled in July 2014 for 19.5 million shares of common stock. At June 30, 2013, we had a $500 million private repurchase contract outstanding that settled in third quarter 2013 for 12.5 million shares of common stock.

	Subsequent Events We have evaluated the effects of events that have occurred subsequent to June 30, 2014, and there have been no material events that would require recognition in our second quarter 2014 consolidated financial statements or disclosure in the Notes to the consolidated financial statements.

We do not have the intent to sell any securities included in the previous table. For debt securities included in the table, we have concluded it is more likely than not that we will not be required to sell prior to recovery of the amortized cost basis. We have assessed each security with gross unrealized losses for credit impairment. For debt securities, we evaluate, where necessary, whether credit impairment exists by comparing the present value of the expected cash flows to the securities' amortized cost basis. For equity securities, we consider numerous factors in determining whether impairment exists, including our intent and ability to hold the securities for a period of time sufficient to recover the cost basis of the securities.
For complete descriptions of the factors we consider when analyzing securities for impairment, see Note 1 (Summary of Significant Accounting Policies) and Note 5 (Investment Securities) to Financial Statements in our 2013 Form 10-K. There have been no material changes to our methodologies for assessing impairment in the first half of 2014.
The following table shows the gross unrealized losses and fair value of debt and perpetual preferred investment securities by those rated investment grade and those rated less than investment grade, according to their lowest credit rating by Standard & Poor's Rating Services (S&P) or Moody's Investors Service (Moody's). Credit ratings express opinions about the credit quality of a security. Securities rated investment grade, that is those rated BBB- or higher by S&P or Baa3 or higher by Moody's, are generally considered by the rating agencies and market participants to be low credit risk. Conversely, securities rated below investment grade, labeled as “speculative grade” by the rating agencies, are considered to be distinctively higher credit risk than investment grade securities. We have also included securities not rated by S&P or Moody's in the table below based on the internal credit grade of the securities (used for credit risk management purposes) equivalent to the credit rating assigned by major credit agencies. The unrealized losses and fair value of unrated securities categorized as investment grade based on internal credit grades were $5 million and $1.6 billion, respectively, at June 30, 2014, and $18 million and $1.9 billion, respectively, at December 31, 2013. If an internal credit grade was not assigned, we categorized the security as non-investment grade.

Represents amounts recorded to OCI for impairment, due to factors other than credit, on debt securities that have also had credit-related OTTI write-downs during the period. Increases represent initial or subsequent non-credit-related OTTI on debt securities. Decreases represent partial to full reversal of impairment due to recoveries in the fair value of securities due to non-credit factors.
The following table presents a rollforward of the credit loss component recognized in earnings for debt securities we still own (referred to as “credit-impaired” debt securities). The credit loss component of the amortized cost represents the difference between the present value of expected future cash flows discounted using the security's current effective interest rate and the amortized cost basis of the security prior to considering credit losses. OTTI recognized in earnings for credit-impaired debt securities is presented as additions and is classified into one of two components based upon whether the current period is the first time the debt security was credit-impaired (initial credit impairment) or if the debt security was previously credit-impaired (subsequent credit impairments). The credit loss component is reduced if we sell, intend to sell or believe we will be required to sell previously credit-impaired debt securities. Additionally, the credit loss component is reduced if we receive or expect to receive cash flows in excess of what we previously expected to receive over the remaining life of the credit-impaired debt security, the security matures or is fully written down.
Changes in the credit loss component of credit-impaired debt securities that were recognized in earnings and related to securities that we do not intend to sell are presented in the following table.

Recoveries of previous credit impairments result from increases in expected cash flows subsequent to credit loss recognition. Such recoveries are reflected prospectively as interest yield adjustments using the effective interest method.

	The following table presents total loans outstanding by portfolio segment and class of financing receivable. Outstanding balances include a total net reduction of $4.8 billion and $6.4 billion at June 30, 2014, and December 31, 2013, respectively, for unearned income, net deferred loan fees, and unamortized discounts and premiums.

	Substantially all of our foreign loan portfolio is commercial loans. Loans are classified as foreign primarily based on whether the borrower's primary address is outside of the United States.
	Loan Purchases, Sales, and Transfers
	The following table summarizes the proceeds paid or received for purchases and sales of loans and transfers from loans held for investment to mortgages/loans held for sale at lower of cost or fair value. This loan activity primarily includes loans purchased and sales of whole loan or participating interests, whereby we receive or transfer a portion of a loan after origination. The table excludes PCI loans and loans recorded at fair value, including loans originated for sale because their loan activity normally does not impact the allowance for credit losses.

	The “Purchases” and “Transfers to MHFS/LHFS" categories exclude activity in government insured/guaranteed real estate 1-4 family first mortgage loans. As servicer, we are able to buy delinquent insured/guaranteed loans out of the Government National Mortgage Association (GNMA) pools. These loans have different risk characteristics from the rest of our consumer portfolio, whereby this activity does not impact the allowance for loan losses in the same manner because the loans are predominantly insured by the Federal Housing Administration (FHA) or guaranteed by the Department of Veterans Affairs (VA). On a net basis, such purchases net of transfers to MHFS were $(1.3) billion and $805 million for the second quarter 2014 and 2013, respectively, and $237 million and $2.8 billion for the first half of 2014 and 2013, respectively.
	Commitments to Lend
	A commitment to lend is a legally binding agreement to lend funds to a customer, usually at a stated interest rate, if funded, and for specific purposes and time periods. We generally require a fee to extend such commitments. Certain commitments are subject to loan agreements with covenants regarding the financial performance of the customer or borrowing base formulas on an ongoing basis that must be met before we are required to fund the commitment. We may reduce or cancel consumer commitments, including home equity lines and credit card lines, in accordance with the contracts and applicable law.
	We may, as a representative for other lenders, advance funds or provide for the issuance of letters of credit under syndicated loan or letter of credit agreements. Any advances are generally repaid in less than a week and would normally require default of both the customer and another lender to expose us to loss. These temporary advance arrangements totaled approximately $87 billion at both June 30, 2014, and December 31, 2013, respectively.
	We issue commercial letters of credit to assist customers in purchasing goods or services, typically for international trade. At June 30, 2014, and December 31, 2013, we had $1.4 billion and $1.2 billion, respectively, of outstanding issued commercial letters of credit. We also originate multipurpose lending commitments under which borrowers have the option to draw on the facility for different purposes in one of several forms, including a standby letter of credit. See Note 10 (Guarantees, Pledged Assets and Collateral) for additional information on standby letters of credit.
	When we make commitments, we are exposed to credit risk. The maximum credit risk for these commitments will generally be lower than the contractual amount because a significant portion of these commitments are expected to expire without being used by the customer. In addition, we manage the potential risk in commitments to lend by limiting the total amount of commitments, both by individual customer and in total, by monitoring the size and maturity structure of these commitments and by applying the same credit standards for these commitments as for all of our credit activities.
	For loans and commitments to lend, we generally require collateral or a guarantee. We may require various types of collateral, including commercial and consumer real estate, autos, other short-term liquid assets such as accounts receivable or inventory and long-lived assets, such as equipment and other business assets. Collateral requirements for each loan or commitment may vary based on the loan product and our assessment of a customer's credit risk according to the specific credit underwriting, including credit terms and structure.
	The contractual amount of our unfunded credit commitments, including unissued standby and commercial letters of credit, is summarized by portfolio segment and class of financing receivable in the following table. The table excludes standby and commercial letters of credit issued under the terms of our commitments and temporary advance commitments on behalf of other lenders.

Certain impaired loans with an allowance calculated by discounting expected cash flows using the loan's effective interest rate over the remaining life of the loan recognize reductions in the allowance as interest income.
For PCI loans, charge-offs are only recorded to the extent that losses exceed the purchase accounting estimates.
The allowance for credit losses includes $8 million and $71 million at June 30, 2014 and 2013, respectively, related to PCI loans acquired from Wachovia. Loans acquired from Wachovia are included in total loans net of related purchase accounting net write-downs.

Credit Quality
We monitor credit quality by evaluating various attributes and utilize such information in our evaluation of the appropriateness of the allowance for credit losses. The following sections provide the credit quality indicators we most closely monitor. The credit quality indicators are generally based on information as of our financial statement date, with the exception of updated Fair Isaac Corporation (FICO) scores and updated loan-to-value (LTV)/combined LTV (CLTV), which are obtained at least quarterly. Generally, these indicators are updated in the second month of each quarter, with updates no older than March 31, 2014. See the “Purchased Credit-Impaired Loans” section of this Note for credit quality information on our PCI portfolio.
Commercial Credit Quality Indicators In addition to monitoring commercial loan concentration risk, we manage a consistent process for assessing commercial loan credit quality. Generally, commercial loans are subject to individual risk assessment using our internal borrower and collateral quality ratings. Our ratings are aligned to Pass and Criticized categories. The Criticized category includes Special Mention, Substandard, and Doubtful categories which are defined by bank regulatory agencies.
The following table provides a breakdown of outstanding commercial loans by risk category. Of the $10.2 billion in criticized commercial real estate (CRE) loans at June 30, 2014, $2.0 billion has been placed on nonaccrual status and written down to net realizable collateral value. CRE loans have a high level of monitoring in place to manage these assets and mitigate loss exposure.

Consumer Credit Quality Indicators We have various classes of consumer loans that present unique risks. Loan delinquency, FICO credit scores and LTV for loan types are common credit quality indicators that we monitor and utilize in our evaluation of the appropriateness of the allowance for credit losses for the consumer portfolio segment.
Many of our loss estimation techniques used for the allowance for credit losses rely on delinquency-based models; therefore, delinquency is an important indicator of credit quality and the establishment of our allowance for credit losses. The following table provides the outstanding balances of our consumer portfolio by delinquency status.

Loans insured/guaranteed by the FHA/VA and 90+ DPD totaled $16.1 billion at June 30, 2014, compared with $20.8 billion at December 31, 2013. At June 30, 2014, all government guaranteed student loans were transferred to loans held for sale. Student loans 90+ DPD totaled $900 million at December 31, 2013.
Of the $7.1 billion of consumer loans not government insured/guaranteed that are 90 days or more past due at June 30, 2014, $775 million was accruing, compared with $7.7 billion past due and $902 million accruing at December 31, 2013.
Real estate 1-4 family first mortgage loans 180 days or more past due totaled $4.7 billion, or 2.0% of total first mortgages (excluding PCI), at June 30, 2014, compared with $5.0 billion, or 2.1%, at December 31, 2013.
The following table provides a breakdown of our consumer portfolio by updated FICO. We obtain FICO scores at loan origination and the scores are updated at least quarterly. The majority of our portfolio is underwritten with a FICO score of 680 and above. FICO is not available for certain loan types and may not be obtained if we deem it unnecessary due to strong collateral and other borrower attributes, primarily securities-based margin loans of $5.3 billion at June 30, 2014, and $5.0 billion at December 31, 2013.

LTV refers to the ratio comparing the loan's unpaid principal balance to the property's collateral value. CLTV refers to the combination of first mortgage and junior lien mortgage (including unused line amounts for credit line products) ratios. LTVs and CLTVs are updated quarterly using a cascade approach which first uses values provided by automated valuation models (AVMs) for the property. If an AVM is not available, then the value is estimated using the original appraised value adjusted by the change in Home Price Index (HPI) for the property location. If an HPI is not available, the original appraised value is used. The HPI value is normally the only method considered for high value properties, generally with an original value of $1 million or more, as the AVM values have proven less accurate for these properties.
The following table shows the most updated LTV and CLTV distribution of the real estate 1-4 family first and junior lien mortgage loan portfolios. We consider the trends in residential real estate markets as we monitor credit risk and establish our allowance for credit losses. In the event of a default, any loss should be limited to the portion of the loan amount in excess of the net realizable value of the underlying real estate collateral value. Certain loans do not have an LTV or CLTV primarily due to industry data availability and portfolios acquired from or serviced by other institutions.

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 $13.2 billion and $17.3 billion at June 30, 2014 and December 31, 2013, respectively, which included $7.1 billion and $10.0 billion, respectively, of loans that are government insured/guaranteed. We commence the foreclosure process on consumer real estate loans when a borrower becomes 120 days delinquent in accordance with Consumer Finance Protection Bureau Guidelines. 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 as to interest or principal are still accruing, because they are (1) well-secured and in the process of collection or (2) real estate 1-4 family mortgage loans or consumer loans exempt under regulatory rules from being classified as nonaccrual until later delinquency, usually 120 days past due. PCI loans of $4.0 billion at June 30, 2014, and $4.5 billion at December 31, 2013, are not included in these past due and still accruing loans even though they are 90 days or more contractually past due. These PCI loans are considered to be accruing because they continue to earn interest from accretable yield, independent of performance in accordance with their contractual terms.
The following table shows non-PCI loans 90 days or more past due and still accruing by class for loans not government insured/guaranteed.

Impaired Loans The table below summarizes key information for impaired loans. Our impaired loans predominantly include loans on nonaccrual status in the commercial portfolio segment and loans modified in a TDR, whether on accrual or nonaccrual status. These impaired loans generally have estimated losses which are included in the allowance for credit losses. We have impaired loans with no allowance for credit losses when loss content has been previously recognized through charge-offs and we do not anticipate additional charge-offs or losses, or certain loans are currently performing in accordance with their terms and for which no loss has been estimated. Impaired loans exclude PCI loans. The table below includes trial modifications that totaled $469 million at June 30, 2014, and $650 million at December 31, 2013.
For additional information on our impaired loans and allowance for credit losses, see Note 1 (Summary of Significant Accounting Policies) in our 2013 Form 10-K.

TROUBLED DEBT RESTRUCTURINGs (TDRs) When, for economic or legal reasons related to a borrower's financial difficulties, we grant a concession for other than an insignificant period of time to a borrower that we would not otherwise consider, the related loan is classified as a TDR. We do not consider any loans modified through a loan resolution such as foreclosure or short sale to be a TDR.
We may require some consumer borrowers experiencing financial difficulty to make trial payments generally for a period of three to four months, according to the terms of a planned permanent modification, to determine if they can perform according to those terms. These arrangements represent trial modifications, which we classify and account for as TDRs. While loans are in trial payment programs, their original terms are not considered modified and they continue to advance through delinquency status and accrue interest according to their original terms. The planned modifications for these arrangements predominantly involve interest rate reductions or other interest rate concessions; however, the exact concession type and resulting financial effect are usually not finalized and do not take effect until the loan is permanently modified. The trial period terms are developed in accordance with our proprietary programs or the U.S. Treasury's Making Home Affordable programs for real estate 1-4 family first lien (i.e. Home Affordable Modification Program – HAMP) and junior lien (i.e. Second Lien Modification Program – 2MP) mortgage loans.
At June 30, 2014, the loans in trial modification period were $143 million under HAMP, $38 million under 2MP and $288 million under proprietary programs, compared with $253 million, $45 million and $352 million at December 31, 2013, respectively. Trial modifications with a recorded investment of $177 million at June 30, 2014, and $286 million at December 31, 2013, were accruing loans and $292 million and $364 million, respectively, were nonaccruing loans. Our experience is that most of the mortgages that enter a trial payment period program are successful in completing the program requirements and are then permanently modified at the end of the trial period. Our allowance process considers the impact of those modifications that are probable to occur.
The following table summarizes our TDR modifications for the periods presented by primary modification type and includes the financial effects of these modifications. For those loans that modify more than once, the table reflects each modification that occurred during the period.

-1	Amounts represent the recorded investment in loans after recognizing the effects of the TDR, if any. 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 $558 million and $647 million, for quarters ended June 30, 2014 and 2013, and $1.2 billion and $1.6 billion for the first half of 2014 and 2013, respectively.
-2	Principal modifications include principal forgiveness at the time of the modification, contingent principal forgiveness granted over the life of the loan based on borrower performance, and principal that has been legally separated and deferred to the end of the loan, with a zero percent contractual interest rate.
-3	Other concessions include loan renewals, term extensions and other interest and noninterest adjustments, but exclude modifications that also forgive principal and/or reduce the contractual interest rate.
-4	Charge-offs include write-downs of the investment in the loan in the period it is contractually modified. The amount of charge-off will differ from the modification terms if the loan has been charged down prior to the modification based on our policies. In addition, there may be cases where we have a charge-off/down with no legal principal modification. Modifications resulted in legally forgiving principal (actual, contingent or deferred) of $44 million and $95 million for quarters ended June 30, 2014 and 2013, and $92 million and $229 million for the first half of 2014 and 2013, respectively.
-5	Reflects the effect of reduced interest rates on loans with principal or interest rate reduction primary modification type.
-6	Trial modifications are granted a delay in payments due under the original terms during the trial payment period. However, these loans continue to advance through delinquency status and accrue interest according to their original terms. Any subsequent permanent modification generally includes interest rate related concessions; however, the exact concession type and resulting financial effect are usually not known until the loan is permanently modified. Trial modifications for the period are presented net of previously reported trial modifications that became permanent in the current period.
The table below summarizes permanent modification TDRs that have defaulted in the current period within 12 months of their permanent modification date. We are reporting these defaulted TDRs based on a payment default definition of 90 days past due for the commercial portfolio segment and 60 days past due for the consumer portfolio segment.

Accretable Yield The excess of cash flows expected to be collected over the carrying value of PCI loans is referred to as the accretable yield and is recognized in interest income using an effective yield method over the remaining life of the loan, or pools of loans. The accretable yield is affected by:
changes in interest rate indices for variable rate PCI loans – expected future cash flows are based on the variable rates in effect at the time of the regular evaluations of cash flows expected to be collected;
changes in prepayment assumptions – prepayments affect the estimated life of PCI loans which may change the amount of interest income, and possibly principal, expected to be collected; and
changes in the expected principal and interest payments over the estimated life – updates to expected cash flows are driven by the credit outlook and actions taken with borrowers. Changes in expected future cash flows from loan modifications are included in the regular evaluations of cash flows expected to be collected.
The change in the accretable yield related to PCI loans is presented in the following table.

	Note 7: Securitizations and Variable Interest Entities
	Involvement with SPEs
	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 or partnerships that are established for a limited purpose. Generally, SPEs are formed in connection with securitization transactions and are considered variable interest entities (VIEs). For further description of our involvement with SPEs, see Note 8 (Securitizations and Variable Interest Entities) to Financial Statements in our 2013 Form 10-K.
	We have segregated our involvement with VIEs between those VIEs which we consolidate, those which we do not consolidate and those for which we account for the transfers of financial assets as secured borrowings. Secured borrowings are transactions involving transfers of our financial assets to third parties that are accounted for as financings with the assets pledged as collateral. Accordingly, the transferred assets remain recognized on our balance sheet. Subsequent tables within this Note further segregate these transactions by structure type.
	The classifications of assets and liabilities in our balance sheet associated with our transactions with VIEs follow:

	Includes the following VIE liabilities at June 30, 2014, and December 31, 2013, respectively, with recourse to the general credit of Wells Fargo: Accrued expenses and other liabilities, $9 million at each date; and Long-term debt, $19 million and $29 million.
	Transactions with Unconsolidated VIEs
	Our transactions with VIEs include securitizations of residential mortgage loans, CRE loans, student loans and auto loans and leases; investment and financing activities involving collateralized debt obligations (CDOs) backed by asset-backed and CRE securities, collateralized loan obligations (CLOs) backed by corporate loans, and other types of structured financing. We have various forms of involvement with VIEs, including holding senior or subordinated interests, entering into liquidity arrangements, credit default swaps and other derivative contracts. Involvements with these unconsolidated VIEs are recorded on our balance sheet primarily in trading assets, investment securities, loans, MSRs, other assets and other liabilities, as appropriate.
	The following tables provide a summary of unconsolidated VIEs with which we have significant continuing involvement, but we are not the primary beneficiary. We do not consider our continuing involvement in an unconsolidated VIE to be significant when it relates to third-party sponsored VIEs for which we were not the transferor or if we were the sponsor but do not have any other significant continuing involvement.
	Significant continuing involvement includes transactions where we were the sponsor or transferor and have other significant forms of involvement. Sponsorship includes transactions with unconsolidated VIEs where we solely or materially participated in the initial design or structuring of the entity or marketing of the transaction to investors. When we transfer assets to a VIE and account for the transfer as a sale, we are considered the transferor. We consider investments in securities held outside of trading, loans, guarantees, liquidity agreements, written options and servicing of collateral to be other forms of involvement that may be significant. We have excluded certain transactions with unconsolidated VIEs from the balances presented in the following table where we have determined that our continuing involvement is not significant due to the temporary nature and size of our variable interests, because we were not the transferor or because we were not involved in the design or operations of the unconsolidated VIEs.

Includes total equity interests of $7.0 billion and $6.9 billion at June 30, 2014, and December 31, 2013, respectively. Also includes debt interests in the form of both loans and securities. Excludes certain debt securities held related to loans serviced for FNMA, FHLMC and GNMA.
Excludes assets and related liabilities with a recorded carrying value on our balance sheet of $1.4 billion and $2.1 billion at June 30, 2014, and December 31, 2013, respectively, for certain delinquent loans that are eligible for repurchase primarily from GNMA loan securitizations. The recorded carrying value represents the amount that would be payable if the Company was to exercise the repurchase option. The carrying amounts are excluded from the table because the loans eligible for repurchase do not represent interests in the VIEs.
Represents senior loans to trusts that are collateralized by asset-backed securities. The trusts invest primarily in senior tranches from a diversified pool of primarily U.S. asset securitizations, of which all are current and 71% and 72% were rated as investment grade by the primary rating agencies at June 30, 2014, and December 31, 2013, respectively. These senior loans are accounted for at amortized cost and are subject to the Company's allowance and credit charge-off policies.
Includes structured financing, auto loan and lease securitizations and credit-linked note structures. Also contains investments in auction rate securities (ARS) issued by VIEs that we do not sponsor and, accordingly, are unable to obtain the total assets of the entity.
In the two preceding tables, “Total VIE assets” represents the remaining principal balance of assets held by unconsolidated VIEs using the most current information available. For VIEs that obtain exposure to assets synthetically through derivative instruments, the remaining notional amount of the derivative is included in the asset balance. “Carrying value” is the amount in our consolidated balance sheet related to our involvement with the unconsolidated VIEs. “Maximum exposure to loss” from our involvement with off-balance sheet entities, which is a required disclosure under GAAP, is determined as the carrying value of our involvement with off-balance sheet (unconsolidated) VIEs plus the remaining undrawn liquidity and lending commitments, the notional amount of net written derivative contracts, and generally the notional amount of, or stressed loss estimate for, other commitments and guarantees. It represents estimated loss that would be incurred under severe, hypothetical circumstances, for which we believe the possibility is extremely remote, such as where the value of our interests and any associated collateral declines to zero, without any consideration of recovery or offset from any economic hedges. Accordingly, this required disclosure is not an indication of expected loss.
For complete descriptions of our types of transactions with unconsolidated VIEs with which we have a significant continuing involvement, but we are not the primary beneficiary, see Note 8 (Securitizations and Variable Interest Entities) to Financial Statements in our 2013 Form 10-K.
OTHER TRANSACTIONS WITH VIEs Auction rate securities (ARS) are debt instruments with long-term maturities, which re-price more frequently, and preferred equities with no maturity. At June 30, 2014, we held in our available-for-sale securities portfolio $605 million of ARS issued by VIEs redeemed pursuant to agreements entered into in 2008 and 2009, compared with $653 million at December 31, 2013.
We do not consolidate the VIEs that issued the ARS because we do not have power over the activities of the VIEs.
TRUST PREFERRED SECURITIES VIEs that we wholly own issue debt securities or preferred equity to third party investors. All of the proceeds of the issuance are invested in debt securities or preferred equity that we issue to the VIEs. The VIEs' operations and cash flows relate only to the issuance, administration and repayment of the securities held by third parties. We do not consolidate these VIEs because the sole assets of the VIEs are receivables from us, even though we own all of the voting equity shares of the VIEs, have fully guaranteed the obligations of the VIEs and may have the right to redeem the third party securities under certain circumstances. In our consolidated balance sheet at June 30, 2014, and December 31, 2013, we reported the debt securities issued to the VIEs as long-term junior subordinated debt with a carrying value of $2.0 billion and $1.9 billion, respectively, and the preferred equity securities issued to the VIEs as preferred stock with a carrying value of $2.5 billion at both dates. These amounts are in addition to the involvements in these VIEs included in the preceding table.
Securitization Activity Related to Unconsolidated VIEs
We use VIEs to securitize consumer and CRE loans and other types of financial assets, including student loans and auto loans. We typically retain the servicing rights from these sales and may continue to hold other beneficial interests in the VIEs. We may also provide liquidity to investors in the beneficial interests and credit enhancements in the form of standby letters of credit. Through these securitizations we may be exposed to liability under limited amounts of recourse as well as standard representations and warranties we make to purchasers and issuers. The following table presents the cash flows with our securitization trusts that were involved in transfers accounted for as sales.

In the second quarter and first half of 2014, we recognized net gains of $68 million and $97 million, respectively, from transfers accounted for as sales of financial assets in securitizations, compared with $46 million and $110 million, respectively, in the same periods of 2013. These net gains primarily relate to commercial mortgage securitizations and residential mortgage securitizations where the loans were not already carried at fair value.
Sales with continuing involvement during the second quarter and first half of 2014 and 2013 predominantly related to securitizations of residential mortgages that are sold to the government-sponsored entities (GSEs), including FNMA, FHLMC and GNMA (conforming residential mortgage securitizations). During the second quarter and first half of 2014, we transferred $36.9 billion and $70.5 billion respectively, in fair value of conforming residential mortgages to unconsolidated VIEs and recorded the transfers as sales, compared with $111.2 billion and $211.9 billion, respectively in the same periods of 2013. Substantially all of these transfers did not result in a gain or loss because the loans were already carried at fair value. In connection with all of these transfers, in the first half of 2014 we recorded a $560 million servicing asset, measured at fair value using a Level 3 measurement technique, and a $22 million liability for repurchase losses which reflects management's estimate of probable losses related to various representations and warranties for the loans transferred, initially measured at fair value. In the first half of 2013, we recorded a $2.0 billion servicing asset and a $98 million liability.
We used the following key weighted-average assumptions to measure mortgage servicing assets at the date of securitization:
			Residential mortgage
			servicing rights
			2014		2013
Quarter ended June 30,
Prepayment speed (1)			12.9	%	11.7
Discount rate			7.3		7.1
Cost to service ($ per loan) (2)		$	301		199
Six months ended June 30,
Prepayment speed (1)			12.5	%	11.8
Discount rate			7.6		7.1
Cost to service ($ per loan) (2)		$	268		189
The prepayment speed assumption for residential mortgage servicing rights includes a blend of prepayment speeds and default rates. Prepayment speed assumptions are influenced by mortgage interest rate inputs as well as our estimation of drivers of borrower behavior.
Includes costs to service and unreimbursed foreclosure costs.
During the second quarter and first half of 2014, we transferred $1.0 billion and $2.3 billion, respectively, in fair value of commercial mortgages to unconsolidated VIEs and recorded the transfers as sales, compared with $1.5 billion and $3.2 billion in the same periods of 2013, respectively. These transfers resulted in gains of $17 million and $41 million in the second quarter and first half of 2014, respectively, because the loans were carried at lower of cost or market value (LOCOM), compared with gains of $38 million and $100 million in the second quarter and first half of 2013. In connection with these transfers, in the first half of 2014 we recorded a servicing asset of $5 million, initially measured at fair value using a Level 3 measurement technique, and securities available-for-sale of $100 million, classified as Level 2. In the first half of 2013, we recorded a servicing asset of $9 million, using a Level 3 measurement technique, and available-for-sale securities of $23 million, classified as Level 2.
The following table provides key economic assumptions and the sensitivity of the current fair value of residential mortgage servicing rights and other retained interests to immediate adverse changes in those assumptions. “Other interests held” relate predominantly to residential and commercial mortgage loan securitizations. Residential mortgage-backed securities retained in securitizations issued through GSEs, such as FNMA, FHLMC and GNMA, are excluded from the table because these securities have a remote risk of credit loss due to the GSE guarantee. These securities also have economic characteristics similar to GSE mortgage-backed securities that we purchase, which are not included in the table. Subordinated interests include only those bonds whose credit rating was below AAA by a major rating agency at issuance. Senior interests include only those bonds whose credit rating was AAA by a major rating agency at issuance. The information presented excludes trading positions held in inventory.

See narrative following this table for a discussion of commercial mortgage servicing rights.
Prepayment speed assumptions do not significantly impact the value of commercial mortgage securitization bonds as the underlying commercial mortgage loans experience significantly lower prepayments due to certain contractual restrictions, impacting the borrower's ability to prepay the mortgage.
The prepayment speed assumption for residential mortgage servicing rights includes a blend of prepayment speeds and default rates. Prepayment speed assumptions are influenced by mortgage interest rate inputs as well as our estimation of drivers of borrower behavior.
In addition to residential mortgage servicing rights (MSRs) included in the previous table, we have a small portfolio of commercial MSRs with a fair value of $1.6 billion at both June 30, 2014, and December 31, 2013. The nature of our commercial MSRs, which are carried at LOCOM, is different from our residential MSRs. Prepayment activity on serviced loans does not significantly impact the value of commercial MSRs because, unlike residential mortgages, commercial mortgages experience significantly lower prepayments due to certain contractual restrictions, impacting the borrower's ability to prepay the mortgage. Additionally, for our commercial MSR portfolio, we are typically master/primary servicer, but not the special servicer, who is separately responsible for the servicing and workout of delinquent and foreclosed loans. It is the special servicer, similar to our role as servicer of residential mortgage loans, who is affected by higher servicing and foreclosure costs due to an increase in delinquent and foreclosed loans. Accordingly, prepayment speeds and costs to service are not key assumptions for commercial MSRs as they do not significantly impact the valuation. The primary economic driver impacting the fair value of our commercial MSRs is forward interest rates, which are derived from market observable yield curves used to price capital markets instruments. Market interest rates most significantly affect interest earned on custodial deposit balances. The sensitivity of the current fair value to an immediate adverse 25% change in the assumption about interest earned on deposit balances at June 30, 2014, and December 31, 2013, results in a decrease in fair value of $176 million and $175 million, respectively. See Note 8 (Mortgage Banking Activities) for further information on our commercial MSRs.
The sensitivities in the preceding paragraph and table are hypothetical and caution should be exercised when relying on this data. Changes in value based on variations in assumptions generally cannot be extrapolated because the relationship of the change in the assumption to the change in value may not be linear. Also, the effect of a variation in a particular assumption on the value of the other interests held is calculated independently without changing any other assumptions. In reality, changes in one factor may result in changes in others (for example, changes in prepayment speed estimates could result in changes in the credit losses), which might magnify or counteract the sensitivities.
The following table presents information about the principal balances of off-balance sheet securitized loans, including residential mortgages sold to FNMA, FHLMC, GNMA and securitizations where servicing is our only form of continuing involvement. Delinquent loans include loans 90 days or more past due and loans in bankruptcy, regardless of delinquency status. In securitizations where servicing is our only form of continuing involvement, we would only experience a loss if required to repurchase a delinquent loan due to a breach in representations and warranties associated with our loan sale or servicing contracts.

At June 30, 2014, and December 31, 2013, the table includes total loans of $1.3 trillion at both dates and delinquent loans of $13.6 billion and $14.0 billion, respectively for FNMA, FHLMC and GNMA. Net charge-offs exclude loans sold to FNMA, FHLMC and GNMA as we do not service or manage the underlying real estate upon foreclosure and, as such, do not have access to net charge-off information.
Transactions with Consolidated VIEs and Secured Borrowings
The following table presents a summary of transfers of financial assets accounted for as secured borrowings and involvements with consolidated VIEs. “Consolidated assets” are presented using GAAP measurement methods, which may include fair value, credit impairment or other adjustments, and therefore in some instances will differ from “Total VIE assets.” For VIEs that obtain exposure synthetically through derivative instruments, the remaining notional amount of the derivative is included in “Total VIE assets.” On the consolidated balance sheet, we separately disclose the consolidated assets of certain VIEs that can only be used to settle the liabilities of those VIEs.

In addition to the transactions included in the previous table, at both June 30, 2014, and December 31, 2013, we had approximately $6.0 billion of private placement debt financing issued through a consolidated VIE. The issuance is classified as long-term debt in our consolidated financial statements. At June 30, 2014, we pledged approximately $6.4 billion in loans (principal and interest eligible to be capitalized), $131 million in available-for-sale securities and $180 million in cash and cash equivalents to collateralize the VIE's borrowings, compared with $6.6 billion, $160 million and $180 million, respectively, at December 31, 2013. These assets were not transferred to the VIE, and accordingly we have excluded the VIE from the previous table.
For complete descriptions of our accounting for transfers accounted for as secured borrowings and involvements with consolidated VIEs see Note 8 (Securitizations and Variable Interest Entities) to Financial Statements in our 2013 Form 10-K.

Represents changes due to collection/realization of expected cash flows over time.
Represents results from free-standing derivatives (economic hedges) used to hedge the risk of changes in fair value of MSRs. See Note 12 (Derivatives) – Free-Standing Derivatives for additional discussion and detail.
The table below summarizes the changes in our liability for mortgage loan repurchase losses. This liability is in “Accrued expenses and other liabilities” in our consolidated balance sheet and the provision for repurchase losses reduces net gains on mortgage loan origination/sales activities in “Mortgage banking” in our consolidated income statement.
Because of the uncertainty in the various estimates underlying the mortgage repurchase liability, there is a range of losses in excess of the recorded mortgage repurchase liability that is reasonably possible. The estimate of the range of possible loss for representations and warranties does not represent a probable loss, and is based on currently available information, significant judgment, and a number of assumptions that are subject to change. The high end of this range of reasonably possible losses in excess of our recorded liability was $975 million at June 30, 2014, and was determined based upon modifying the assumptions (particularly to assume significant changes in investor repurchase demand practices) utilized in our best estimate of probable loss to reflect what we believe to be the high end of reasonably possible adverse assumptions.

	For our goodwill impairment analysis, we allocate all of the goodwill to the individual operating segments. We identify reporting units that are one level below an operating segment (referred to as a component), and distinguish these reporting units based on how the segments and components are managed, taking into consideration the economic characteristics, nature of the products and customers of the components. At the time we acquire a business, we allocate goodwill to applicable reporting units based on their relative fair value, and if we have a significant business reorganization, we may reallocate the goodwill. See Note 18 (Operating Segments) for further information on management reporting.

Guarantees, Pledged Assets and Collateral	'
	Note 10: Guarantees, Pledged Assets and Collateral
	Guarantees are contracts that contingently require us to make payments to a guaranteed party based on an event or a change in an underlying asset, liability, rate or index. Guarantees are generally in the form of standby letters of credit, securities lending and other indemnifications, written put options, recourse obligations, and other types of arrangements. For complete descriptions of our guarantees, see Note 14 (Guarantees, Pledged Assets and Collateral) to Financial Statements in our 2013 Form 10-K. The following table shows carrying value, maximum exposure to loss on our guarantees and the related non-investment grade amounts.

	Total maximum exposure to loss includes direct pay letters of credit (DPLCs) of $ 16.4 billion and $16.8 billion at June 30, 2014 and December 31, 2013, respectively. We issue DPLCs to provide credit enhancements for certain bond issuances. Beneficiaries (bond trustees) may draw upon these instruments to make scheduled principal and interest payments, redeem all outstanding bonds because a default event has occurred, or for other reasons as permitted by the agreement. We also originate multipurpose lending commitments under which borrowers have the option to draw on the facility in one of several forms, including as a standby letter of credit. Total maximum exposure to loss includes the portion of these facilities for which we have issued standby letters of credit under the commitments.
	Includes $244 million and $337 million at June 30, 2014 and December 31, 2013, respectively, in debt and equity securities lent from participating institutional client portfolios to third-party borrowers. Also includes indemnifications provided to certain third-party clearing agents. Outstanding customer obligations under these arrangements were $951 million and $769 million with related collateral of $5.7 billion and $3.7 billion at June 30, 2014 and December 31, 2013, respectively. Estimated maximum exposure to loss was $3.0 billion and $2.9 billion as of the same periods, respectively.
	Written put options, which are in the form of derivatives, are also included in the derivative disclosures in Note 12 (Derivatives).
	Represent recourse provided, predominantly to the GSEs, on loans sold under various programs and arrangements. Under these arrangements, we repurchased $4 million and $5 million respectively, of loans associated with these agreements in the second quarter and first half of 2014, and $7 million and $18 million in the same periods of 2013, respectively.
	Consists of guarantees made under certain factoring arrangements to purchase trade receivables from third parties, generally upon their request, if receivable debtors default on their payment obligations. See Note 1 (Summary of Significant Accounting Policies) for additional information.
	Includes amounts for liquidity agreements and contingent consideration that were previously reported separately.
	“Maximum exposure to loss” and “Non-investment grade” are required disclosures under GAAP. Non-investment grade represents those guarantees on which we have a higher risk of being required to perform under the terms of the guarantee. If the underlying assets under the guarantee are non-investment grade (that is, an external rating that is below investment grade or an internal credit default grade that is equivalent to a below investment grade external rating), we consider the risk of performance to be high. Internal credit default grades are determined based upon the same credit policies that we use to evaluate the risk of payment or performance when making loans and other extensions of credit. These credit policies are further described in Note 5 (Loans and Allowance for Credit Losses).
	Maximum exposure to loss represents the estimated loss that would be incurred under an assumed hypothetical circumstance, despite what we believe is its extremely remote possibility, where the value of our interests and any associated collateral declines to zero. Maximum exposure to loss estimates in the table above do not reflect economic hedges or collateral we could use to offset or recover losses we may incur under our guarantee agreements. Accordingly, this required disclosure is not an indication of expected loss. We believe the carrying value, which is either fair value for derivative-related products or the allowance for lending- related commitments, is more representative of our exposure to loss than maximum exposure to loss.
	Pledged Assets
	As part of our liquidity management strategy, we pledge assets to secure trust and public deposits, borrowings and letters of credit from the FHLB and FRB, securities sold under agreements to repurchase (repurchase agreements), and for other purposes as required or permitted by law or insurance statutory requirements. The types of collateral we pledge include securities issued by federal agencies, GSEs, domestic and foreign companies and various commercial and consumer loans. The following table provides the total carrying amount of pledged assets by asset type, of which substantially all are pursuant to agreements that do not permit the secured party to sell or repledge the collateral. The table excludes pledged consolidated VIE assets of $7.2 billion and $8.1 billion at June 30, 2014, and December 31, 2013, respectively, which can only be used to settle the liabilities of those entities. The table also excludes $13.9 billion and $15.3 billion in assets pledged in transactions accounted for as secured borrowings at June 30, 2014 and December 31, 2013, respectively. See Note 7 (Securitizations and Variable Interest Entities) for additional information on consolidated VIE assets and secured borrowings.

		Total pledged assets		$	551,882		497,353
	-1	Represent assets pledged to collateralize repurchase agreements and other securities financings. Balance includes $44.0 billion and $29.0 billion at June 30, 2014, and December 31, 2013, respectively, under agreements that permit the secured parties to sell or repledge the collateral.
	-2	Includes $7.1 billion and $8.7 billion in collateral for repurchase agreements at June 30, 2014, and December 31, 2013, respectively, which are pledged under agreements that do not permit the secured parties to sell or repledge the collateral.
	-3	Represent loans carried at amortized cost, which are pledged under agreements that do not permit the secured parties to sell or repledge the collateral. Amounts exclude $1.4 billion and $2.1 billion at June 30, 2014 and December 31, 2013, respectively, of pledged loans recorded on our balance sheet representing certain delinquent loans that are eligible for repurchase primarily from GNMA loan securitizations. See Note 7 (Securitizations and Variable Interest Entities) for additional information.
	Offsetting of Resale and Repurchase Agreements and Securities Borrowing and Lending Agreements
	The table below presents resale and repurchase agreements subject to master repurchase agreements (MRA) and securities borrowing and lending agreements subject to master securities lending agreements (MSLA). We account for transactions subject to these agreements as collateralized financings and those with a single counterparty are presented net on our balance sheet, provided certain criteria are met that permit balance sheet netting. Most transactions subject to these agreements do not meet those criteria and thus are not eligible for balance sheet netting.
	Collateral we pledged consists of non-cash instruments, such as securities or loans, and is not netted on the balance sheet against the related collateralized liability. Collateral we received includes securities or loans and is not recognized on our balance sheet. Collateral received or pledged 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 amount of such collateral to the amount of the related recognized asset or liability for each counterparty.
	In addition to the amounts included in the table below, we also have balance sheet netting related to derivatives that is disclosed within Note 12 (Derivatives).

	Note 11: Legal Actions
	The following supplements our discussion of certain matters previously reported in Note 15 (Legal Actions) to Financial Statements in our 2013 Form 10-K and Note 11 (Legal Actions) to Financial Statements in our 2014 first quarter Quarterly Report on Form 10-Q for events occurring during second quarter 2014.
	FHA INSURANCE LITIGATION  On October 9, 2012, the United States filed a complaint, captioned United States of America v. Wells Fargo Bank, N.A., in the U.S. District Court for the Southern District of New York. The complaint makes claims with respect to Wells Fargo's Federal Housing Administration (FHA) lending program for the period 2001 to 2010. The complaint alleges, among other allegations, that Wells Fargo improperly certified certain FHA mortgage loans for United States Department of Housing and Urban Development (HUD) insurance that did not qualify for the program, and therefore Wells Fargo should not have received insurance proceeds from HUD when some of the loans later defaulted. The complaint further alleges Wells Fargo knew some of the mortgages did not qualify for insurance and did not disclose the deficiencies to HUD before making insurance claims. On December 1, 2012, Wells Fargo filed a motion in the U.S. District Court for the District of Columbia seeking to enforce a release of Wells Fargo given by the United States, which was denied on February 12, 2013. On April 11, 2013, Wells Fargo appealed the decision to the U.S. Court of Appeals for the District of Columbia Circuit. The Court affirmed the denial of Wells Fargo's motion on June 20, 2014.
	MARYLAND MORTGAGE LENDING LITIGATION  On July 8, 2008, a class action complaint captioned Stacey and Bradley Petry, et al., v. Wells Fargo Bank, N.A., et al., was filed. The complaint alleges that Wells Fargo and others violated the Maryland Finder's Fee Act in the closing of mortgage loans in Maryland. On March 13, 2013, the Court held the plaintiff class did not have sufficient evidence to proceed to trial, which was previously set for March 18, 2013. On June 20, 2013, the Court entered judgment in favor of the defendants. The plaintiffs appealed. The U.S. Court of Appeals for the Fourth Circuit affirmed the judgment in favor of the defendants on July 10, 2014.
	SECURITIES LENDING LITIGATION Wells Fargo Bank, N.A. is involved in five separate pending actions brought by securities lending customers of Wells Fargo and Wachovia Bank in various courts. In general, each of the cases alleges that Wells Fargo violated fiduciary and contractual duties by investing collateral for loaned securities in investments that suffered losses. One of the cases, filed on March 27, 2012, is composed of a class of Wells Fargo securities lending customers in a case captioned City of Farmington Hills Employees Retirement System v. Wells Fargo Bank, N.A. The class action is pending in the U.S. District Court for the District of Minnesota. On April 12, 2014, the parties reached a settlement in principle of the class action case. The settlement was preliminarily approved by the Court on June 5, 2014. A hearing on final approval is set for August 14, 2014.
	OUTLOOK When establishing a liability for contingent litigation losses, the Company determines a range of potential losses for each matter that is both probable and estimable, and records the amount it considers to be the best estimate within the range. The high end of the range of reasonably possible potential litigation losses in excess of the Company's liability for probable and estimable losses was $1.2 billion as of June 30, 2014. For these matters and others where an unfavorable outcome is reasonably possible but not probable, there may be a range of possible losses in excess of the established liability that cannot be estimated. 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, including the matters described above, will not, individually or in the aggregate, have a material adverse effect on Wells Fargo's consolidated financial position. However, in the event of unexpected future developments, it is possible that the ultimate resolution of those matters, 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 12: Derivatives
	We primarily 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 derivatives either as hedging instruments in a qualifying hedge accounting relationship (fair value or cash flow hedge) or as free-standing derivatives. Free-standing derivatives include economic hedges that do not qualify for hedge accounting and derivatives held for customer accommodation or other trading purposes. For more information on our derivative activities, see Note 16 (Derivatives) to Financial Statements in our 2013 Form 10-K.
	The following table presents the total notional or contractual amounts and fair values for our derivatives. Derivative transactions can be measured in terms of the notional amount, but this amount is not recorded on the balance sheet and is not, when viewed in isolation, a meaningful measure of the risk profile of the instruments. The notional amount is generally not exchanged, but is used only as the basis on which interest and other payments are determined. Derivatives designated as qualifying hedge contracts and free-standing derivatives (economic hedges) are recorded on the balance sheet at fair value in other assets or other liabilities. Customer accommodation, trading and other free-standing derivatives are recorded on the balance sheet at fair value in trading assets, other assets or other liabilities.

	Notional amounts presented exclude $3.2 billion and $1.9 billion at June 30, 2014 and December 31, 2013, respectively, of certain derivatives that are combined for designation as a hedge on a single instrument.
	Includes free-standing derivatives (economic hedges) used to hedge the risk of changes in the fair value of residential MSRs, MHFS, loans, derivative loan commitments and other interests held.
	Represents balance sheet netting of derivative asset and liability balances, and related cash collateral. See the next table in this Note for further information.
	The following table provides information on the gross fair values of derivative assets and liabilities, the balance sheet netting adjustments and the resulting net fair value amount recorded on our balance sheet, as well as the non-cash collateral associated with such arrangements. We execute substantially all of our derivative transactions under master netting arrangements. We reflect all derivative balances and related cash collateral subject to enforceable master netting arrangements on a net basis within the balance sheet. The “Gross amounts recognized” column in the following table include $54.0 billion and $58.2 billion of gross derivative assets and liabilities, respectively, at June 30, 2014, and $59.8 billion and $66.1 billion, respectively, at December 31, 2013, with counterparties subject to enforceable master netting arrangements that are carried on the balance sheet net of offsetting amounts. The remaining gross derivative assets and liabilities of $14.3 billion and $7.4 billion, respectively, at June 30, 2014 and $12.9 billion and $7.3 billion, respectively, at December 31, 2013, include those with counterparties subject to master netting arrangements for which we have not assessed the enforceability because they are with counterparties where we do not currently have positions to offset, those subject to master netting arrangements where we have not been able to confirm the enforceability and those not subject to master netting arrangements. As such, we do not net derivative balances or collateral within the balance sheet for these counterparties.
	We determine the balance sheet netting adjustments based on the terms specified within each master netting arrangement. We disclose the balance sheet netting amounts within the column titled “Gross amounts offset in consolidated balance sheet.” Balance sheet netting adjustments are determined at the counterparty level for which there may be multiple contract types. For disclosure purposes, we allocate these adjustments to the contract type for each counterparty proportionally based upon the “Gross amounts recognized” by counterparty. As a result, the net amounts disclosed by contract type may not represent the actual exposure upon settlement of the contracts.
	Balance sheet netting does not include non-cash collateral that we pledge. For disclosure purposes, we present these amounts in the column titled “Gross amounts not offset in consolidated balance sheet (Disclosure-only netting)” within the table. We determine and allocate the Disclosure-only netting amounts in the same manner as balance sheet netting amounts.
	The “Net amounts” column within the following table represents the aggregate of our net exposure to each counterparty after considering the balance sheet and Disclosure-only netting adjustments. We manage derivative exposure by monitoring the credit risk associated with each counterparty using counterparty specific credit risk limits, using master netting arrangements and obtaining collateral. Derivative contracts executed in over-the-counter markets include bilateral contractual arrangements that are not cleared through a central clearing organization but are typically subject to master netting arrangements. The percentage of our bilateral derivative transactions outstanding at period end in such markets, based on gross fair value, is provided within the following table. Other derivative contracts executed in over-the-counter or exchange-traded markets are settled through a central clearing organization and are excluded from this percentage. In addition to the netting amounts included in the table, we also have balance sheet netting related to resale and repurchase agreements that are disclosed within Note 10 (Guarantees, Pledged Assets and Collateral).

-1	Represents amounts with counterparties subject to enforceable master netting arrangements that have been offset in the consolidated balance sheet, including related cash collateral and portfolio level counterparty valuation adjustments. Counterparty valuation adjustments were $207 million and $236 million related to derivative assets and $49 million and $67 million related to derivative liabilities as of June 30, 2014 and December 31, 2013, respectively. Cash collateral totaled $4.7 billion and $10.6 billion, netted against derivative assets and liabilities, respectively, at June 30, 2014, and $4.3 billion and $11.3 billion, respectively, at December 31, 2013.
-2	Net derivative assets of $12.4 billion and $14.4 billion are classified in Trading assets as of June 30, 2014 and December 31, 2013, respectively. $5.0 billion and $1.4 billion are classified in Other assets in the consolidated balance sheet as of June 30, 2014 and December 31, 2013, respectively. Net derivative liabilities are classified in Accrued expenses and other liabilities in the consolidated balance sheet.
-3	Represents non-cash collateral pledged and received against derivative assets and liabilities with the same counterparty that are subject to enforceable master netting arrangements. U.S. GAAP does not permit netting of such non-cash collateral balances in the consolidated balance sheet but requires disclosure of these amounts.
-4	Represents derivatives executed in over-the-counter markets not settled through a central clearing organization. Over-the-counter percentages are calculated based on Gross amounts recognized as of the respective balance sheet date. The remaining percentage represents derivatives settled through a central clearing organization, which are executed in either over-the-counter or exchange-traded markets.
Fair Value Hedges
We use derivatives to hedge against changes in fair value of certain financial instruments, including available-for-sale debt securities, mortgages held for sale, and long-term debt. For more information on fair value hedges, see Note 16 (Derivatives) to Financial Statements in our 2013 Form 10-K.
The following table shows the net gains (losses) recognized in the income statement related to derivatives in fair value hedging relationships. The entire derivative gain or loss is included in the assessment of hedge effectiveness for all fair value hedge relationships, except for those involving foreign-currency denominated available-for-sale securities and long-term debt hedged with foreign currency forward derivatives for which the time value component of the derivative gain or loss related to the changes in the difference between the spot and forward price is excluded from the assessment of hedge effectiveness.

Cash Flow Hedges
We use derivatives to hedge certain financial instruments against future interest rate increases and to limit the variability of cash flows on certain financial instruments due to changes in the benchmark interest rate. For more information on cash flow hedges, see Note 16 (Derivatives) to Financial Statements in our 2013 Form 10-K.
Based upon current interest rates, we estimate that $290 million (pre tax) of deferred net gains on derivatives in OCI at June 30, 2014, will be reclassified into net interest income during the next twelve months. Future changes to interest rates may significantly change actual amounts reclassified to earnings. We are hedging our exposure to the variability of future cash flows for all forecasted transactions for a maximum of 7 years for both hedges of floating-rate debt and floating-rate commercial loans.

None of the change in value of the derivatives was excluded from the assessment of hedge effectiveness.
Free-Standing Derivatives
We use free-standing derivatives (economic hedges) to hedge the risk of changes in the fair value of certain residential MHFS, certain loans held for investment, residential MSRs measured at fair value, derivative loan commitments and other interests held. The resulting gain or loss on these economic hedges is reflected in mortgage banking noninterest income, net gains (losses) from equity investments and other noninterest income.
The derivatives used to hedge MSRs measured at fair value, resulted in net derivative gains of $1.3 billion and $ 2.2 billion in second quarter and first half of 2014, respectively, and net derivative losses of $1.8 billion and $2.4 billion in second quarter and first half of 2013, respectively, which are included in mortgage banking noninterest income. The aggregate fair value of these derivatives was a net asset of $492 million at June 30, 2014 and a net liability of $531 million at December 31, 2013. The change in fair value of these derivatives for each period end is due to changes in the underlying market indices and interest rates as well as the purchase and sale of derivative financial instruments throughout the period as part of our dynamic MSR risk management process.
Interest rate lock commitments for residential mortgage loans that we intend to sell are considered free-standing derivatives. The aggregate fair value of derivative loan commitments on the balance sheet was a net asset of $124 million and a net liability of $26 million at June 30, 2014 and December 31, 2013, respectively, and is included in the caption “Interest rate contracts” under “Customer accommodation, trading and other free-standing derivatives” in the first table in this Note.

Credit Derivatives
We use credit derivatives primarily to assist customers with their risk management objectives. We may also use credit derivatives in structured product transactions or liquidity agreements written to special purpose vehicles. The maximum exposure of sold credit derivatives is managed through posted collateral, purchased credit derivatives and similar products in order to achieve our desired credit risk profile. This credit risk management provides an ability to recover a significant portion of any amounts that would be paid under the sold credit derivatives. We would be required to perform under the noted credit derivatives in the event of default by the referenced obligors. Events of default include events such as bankruptcy, capital restructuring or lack of principal and/or interest payment. In certain cases, other triggers may exist, such as the credit downgrade of the referenced obligors or the inability of the special purpose vehicle for which we have provided liquidity to obtain funding.

-1	Amounts previously reported for "Protection sold - non-investment grade" have been revised to reflect a corrected determination of the investment grade status of sold credit protection.
Protection sold represents the estimated maximum exposure to loss that would be incurred under an assumed hypothetical circumstance, where the value of our interests and any associated collateral declines to zero, without any consideration of recovery or offset from any economic hedges. We believe this hypothetical circumstance to be an extremely remote possibility and accordingly, this required disclosure is not an indication of expected loss. The amounts under non-investment grade represent the notional amounts of those credit derivatives on which we have a higher risk of being required to perform under the terms of the credit derivative and are a function of the underlying assets.
We consider the risk of performance to be high if the underlying assets under the credit derivative have an external rating that is below investment grade or an internal credit default grade that is equivalent thereto. We believe the net protection sold, which is representative of the net notional amount of protection sold and purchased with identical underlyings, in combination with other protection purchased, is more representative of our exposure to loss than either non-investment grade or protection sold. Other protection purchased represents additional protection, which may offset the exposure to loss for protection sold, that was not purchased with an identical underlying of the protection sold.
Credit-Risk Contingent Features
Certain of our derivative contracts contain provisions whereby if the credit rating of our debt were to be downgraded by certain major credit rating agencies, the counterparty could demand additional collateral or require termination or replacement of derivative instruments in a net liability position. The aggregate fair value of all derivative instruments with such credit-risk-related contingent features that are in a net liability position was $11.4 billion at June 30, 2014, and $14.3 billion at December 31, 2013, respectively, for which we posted $9.9 billion and $12.2 billion, respectively, in collateral in the normal course of business. If the credit rating of our debt had been downgraded below investment grade, which is the credit-risk-related contingent feature that if triggered requires the maximum amount of collateral to be posted, on June 30, 2014, or December 31, 2013, we would have been required to post additional collateral of $1.5 billion or $2.5 billion, respectively, or potentially settle the contract in an amount equal to its fair value.
Counterparty Credit Risk
By using derivatives, we are exposed to counterparty credit risk if counterparties to the derivative contracts do not perform as expected. If a counterparty fails to perform, our counterparty credit risk is equal to the amount reported as a derivative asset on our balance sheet. The amounts reported as a derivative asset are derivative contracts in a gain position, and to the extent subject to legally enforceable master netting arrangements, net of derivatives in a loss position with the same counterparty and cash collateral received. We minimize counterparty credit risk through credit approvals, limits, monitoring procedures, executing master netting arrangements and obtaining collateral, where appropriate. To the extent the master netting arrangements and other criteria meet the applicable requirements, including determining the legal enforceability of the arrangement, it is our policy to present derivative balances and related cash collateral amounts net on the balance sheet. We incorporate credit valuation adjustments (CVA) to reflect counterparty credit risk and our own credit risk in determining the fair value of our derivatives. Such adjustments, which consider the effects of enforceable master netting agreements and collateral arrangements, reflect market-based views of the credit quality of each counterparty. Our CVA calculation is determined based on observed credit spreads in the credit default swap market and indices indicative of the credit quality of the counterparties to our derivatives.

Fair Value Disclosures [Abstract]	'
Fair Values of Assets and Liabilities	'
Note 13: Fair Values of Assets and Liabilities
We use fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. Assets and liabilities recorded at fair value on a recurring basis are presented in the recurring table in this Note. From time to time, we may be required to record at fair value other assets on a nonrecurring basis, such as certain residential and commercial MHFS, certain LHFS, loans held for investment and certain other assets. These nonrecurring fair value adjustments typically involve application of lower-of-cost-or-market accounting or write-downs of individual assets.
See Note 1 (Summary of Significant Accounting Policies) to Financial Statements in our 2013 Form 10-K for discussion of how we determine fair value. For descriptions of the valuation methodologies we use for assets and liabilities recorded at fair value on a recurring or nonrecurring basis and for estimating fair value for financial instruments not recorded at fair value, see Note 17 (Fair Values of Assets and Liabilities) to Financial Statements in our 2013 Form 10-K.
Fair Value Hierarchy We group our assets and liabilities measured at fair value in three levels based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. These levels are:
Level 1 – Valuation is based upon quoted prices for identical instruments traded in active markets.
Level 2 – Valuation is based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market.
Level 3 – Valuation is generated from techniques that use significant assumptions not observable in the market. These unobservable assumptions reflect estimates of assumptions that market participants would use in pricing the asset or liability. Valuation techniques include use of option pricing models, discounted cash flow models and similar techniques.
Fair Value Measurements from Brokers or Third Party Pricing Services
For certain assets and liabilities, we obtain fair value measurements from brokers or third party pricing services and record the unadjusted fair value in our financial statements. The detail by level is shown in the table below. Fair value measurements obtained from brokers or third party pricing services that we have adjusted to determine the fair value recorded in our financial statements are not included in the following table.

Changes in Fair Value Levels
We monitor the availability of observable market data to assess the appropriate classification of financial instruments within the fair value hierarchy and transfer between Level 1, Level 2, and Level 3 accordingly. Observable market data includes but is not limited to quoted prices and market transactions. Changes in economic conditions or market liquidity generally will drive changes in availability of observable market data. Changes in availability of observable market data, which also may result in changing the valuation technique used, are generally the cause of transfers between Level 1, Level 2, and Level 3.
Transfers into and out of Level 1, Level 2, and Level 3 for the periods presented are provided within the following table. The amounts reported as transfers represent the fair value as of the beginning of the quarter in which the transfer occurred.

The following table provides quantitative information about the valuation techniques and significant unobservable inputs used in the valuation of substantially all of our Level 3 assets and liabilities measured at fair value on a recurring basis for which we use an internal model.
The significant unobservable inputs for Level 3 assets and liabilities that are valued using fair values obtained from third party vendors are not included in the table, as the specific inputs applied are not provided by the vendor. In addition, the table excludes the valuation techniques and significant unobservable inputs for certain classes of Level 3 assets and liabilities measured using an internal model that we consider, both individually and in the aggregate, insignificant relative to our overall Level 3 assets and liabilities. We made this determination based upon an evaluation of each class which considered the magnitude of the positions, nature of the unobservable inputs and potential for significant changes in fair value due to changes in those inputs. For information on how changes in significant unobservable inputs affect the fair values of Level 3 assets and liabilities, see Note 17 (Fair Values of Assets and Liabilities) to Financial Statements in our 2013 Form 10-K.

Consists of total Level 3 assets of $37.2 billion and total Level 3 liabilities of $3.7 billion, before netting of derivative balances.
The valuation techniques used for our Level 3 assets and liabilities, as presented in the previous table, are described as follows:
Discounted cash flow - Discounted cash flow valuation techniques generally consist of developing an estimate of future cash flows that are expected to occur over the life of an instrument and then discounting those cash flows at a rate of return that results in the fair value amount.
Option model - Option model valuation techniques are generally used for instruments in which the holder has a contingent right or obligation based on the occurrence of a future event, such as the price of a referenced asset going above or below a predetermined strike price. Option models estimate the likelihood of the specified event occurring by incorporating assumptions such as volatility estimates, price of the underlying instrument and expected rate of return.
Market comparable pricing - Market comparable pricing valuation techniques are used to determine the fair value of certain instruments by incorporating known inputs, such as recent transaction prices, pending transactions, or prices of other similar investments that require significant adjustment to reflect differences in instrument characteristics.
Vendor-priced – Prices obtained from third party pricing vendors or brokers that are used to record the fair value of the asset or liability, of which the related valuation technique and significant unobservable inputs are not provided.
Significant unobservable inputs presented in the previous table are those we consider significant to the fair value of the Level 3 asset or liability. We consider unobservable inputs to be significant, if by their exclusion, the fair value of the Level 3 asset or liability would be impacted by a predetermined percentage change or based on qualitative factors, such as nature of the instrument, type of valuation technique used, and the significance of the unobservable inputs relative to other inputs used within the valuation. Following is a description of the significant unobservable inputs provided in the table.
Comparability adjustment – is an adjustment made to observed market data, such as a transaction price in order to reflect dissimilarities in underlying collateral, issuer, rating, or other factors used within a market valuation approach, expressed as a percentage of an observed price.
Conversion Factor – is the risk-adjusted rate in which a particular instrument may be exchanged for another instrument upon settlement, expressed as a percentage change from a specified rate.
Correlation factor - is the likelihood of one instrument changing in price relative to another based on an established relationship expressed as a percentage of relative change in price over a period over time.
Cost to service - is the expected cost per loan of servicing a portfolio of loans, which includes estimates for unreimbursed expenses (including delinquency and foreclosure costs) that may occur as a result of servicing such loan portfolios.
Credit spread – is the portion of the interest rate in excess of a benchmark interest rate, such as OIS, LIBOR or U.S. Treasury rates, that when applied to an investment captures changes in the obligor's creditworthiness.
Default rate – is an estimate of the likelihood of not collecting contractual amounts owed expressed as a constant default rate (CDR).
Discount rate – is a rate of return used to present value the future expected cash flow to arrive at the fair value of an instrument. The discount rate consists of a benchmark rate component and a risk premium component. The benchmark rate component, for example, OIS, LIBOR or U.S. Treasury rates, is generally observable within the market and is necessary to appropriately reflect the time value of money. The risk premium component reflects the amount of compensation market participants require due to the uncertainty inherent in the instruments' cash flows resulting from risks such as credit and liquidity.
Fall-out factor - is the expected percentage of loans associated with our interest rate lock commitment portfolio that are likely of not funding.
Initial-value servicing - is the estimated value of the underlying loan, including the value attributable to the embedded servicing right, expressed in basis points of outstanding unpaid principal balance.
Loss severity – is the percentage of contractual cash flows lost in the event of a default.
Prepayment rate – is the estimated rate at which forecasted prepayments of principal of the related loan or debt instrument are expected to occur, expressed as a constant prepayment rate (CPR).
Utilization rate – is the estimated rate in which incremental portions of existing reverse mortgage credit lines are expected to be drawn by borrowers, expressed as an annualized rate.
Volatility factor – is the extent of change in price an item is estimated to fluctuate over a specified period of time expressed as a percentage of relative change in price over a period over time.
Weighted average life – is the weighted average number of years an investment is expected to remain outstanding based on its expected cash flows reflecting the estimated date the issuer will call or extend the maturity of the instrument or otherwise reflecting an estimate of the timing of an instrument's cash flows whose timing is not contractually fixed.
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 or write-downs of individual assets. The following table provides the fair value hierarchy and carrying amount of all assets that were still held as of June 30, 2014, and December 31, 2013, and for which a nonrecurring fair value adjustment was recorded during the periods presented.

The table below provides quantitative information about the valuation techniques and significant unobservable inputs used in the valuation of substantially all of our Level 3 assets and liabilities measured at fair value on a nonrecurring basis for which we use an internal model.
We have excluded from the table classes of Level 3 assets and liabilities measured using an internal model that we consider, both individually and in the aggregate, insignificant relative to our overall Level 3 nonrecurring measurements. We made this determination based upon an evaluation of each class which considered the magnitude of the positions, nature of the unobservable inputs and potential for significant changes in fair value due to changes in those inputs.

Refer to the narrative following the recurring quantitative Level 3 table of this Note for a definition of the valuation technique(s) and significant unobservable inputs.
For residential MHFS, weighted averages are calculated using outstanding unpaid principal balance of the loans.
Consists of approximately $1.2 billion and $825 million government insured/guaranteed loans purchased from GNMA-guaranteed mortgage securitizations, at June 30, 2014 and December 31, 2013, respectively and $82 million and $68 million of other mortgage loans which are not government insured/guaranteed at June 30, 2014 and December 31, 2013, respectively.
Represents a single investment. For additional information, see the “Alternative Investments” section in this Note.
Applies only to non-government insured/guaranteed loans.
Includes the impact on prepayment rate of expected defaults for the government insured/guaranteed loans, which affects the frequency and timing of early resolution of loans.
Alternative Investments
The following table summarizes our investments in various types of funds for which we use net asset values (NAVs) per share as a practical expedient to measure fair value on recurring and nonrecurring bases. The investments are included in trading assets, available-for-sale securities, and other assets. The table excludes those investments that are probable of being sold at an amount different from the funds' NAVs.

Excludes a private equity fund investment of $203 million and $505 million at June 30, 2014, and December 31, 2013, respectively, for which we recorded nonrecurring fair value adjustments during the periods then ended. This investment is probable of being sold for an amount different from the fund's NAV; therefore, the investment's fair value has been estimated using recent transaction information. This investment is subject to the Volcker Rule, which includes provisions that restrict banking entities from owning interests in certain types of funds.
Includes certain investments subject to the Volcker Rule that we may have to divest.
June 30, 2014, and December 31, 2013, include $1.6 billion and 1.5 billion, respectively, of fair value for nonmarketable equity investments carried at cost for which we use NAVs as a practical expedient to determine nonrecurring fair value adjustments. The fair values of investments that had nonrecurring fair value adjustments were $72 million and $88 million at June 30, 2014, and December 31, 2013, respectively.
Offshore funds primarily invest in foreign mutual funds. Redemption restrictions are in place for these investments with a fair value of $32 million and $144 million at June 30, 2014 and December 31, 2013, respectively, due to lock-up provisions that will remain in effect until October 2015.
Private equity funds invest in equity and debt securities issued by private and publicly-held companies in connection with leveraged buyouts, recapitalizations and expansion opportunities. Substantially all of these investments do not allow redemptions. Alternatively, we receive distributions as the underlying assets of the funds liquidate, which we expect to occur over the next 6 years.
Venture capital funds invest in domestic and foreign companies in a variety of industries, including information technology, financial services and healthcare. These investments can never be redeemed with the funds. Instead, we receive distributions as the underlying assets of the fund liquidate, which we expect to occur over the next 5 years.
Fair Value Option
We elect the fair value option to account for certain financial instruments. For more information, including the basis for the elections, see Note 17 (Fair Values of Assets and Liabilities) to Financial Statements in our 2013 Form 10-K.
The following table reflects differences between the fair value carrying amount of certain assets and liabilities for which we have elected the fair value option and the contractual aggregate unpaid principal amount at maturity.

Represents collateralized, non-recourse debt securities issued by certain of our consolidated securitization VIEs that are held by third party investors. To the extent cash flows from the underlying collateral are not sufficient to pay the unpaid principal amount of the debt, those third party investors absorb losses.
The assets and liabilities accounted for under the fair value option are initially measured at fair value. Gains and losses from initial measurement and subsequent changes in fair value are recognized in earnings.

For performing loans, instrument-specific credit risk gains or losses were derived principally by determining the change in fair value of the loans due to changes in the observable or implied credit spread. Credit spread is the market yield on the loans less the relevant risk-free benchmark interest rate. For nonperforming loans, we attribute all changes in fair value to instrument-specific credit risk. The following table shows the estimated gains and losses from earnings attributable to instrument-specific credit risk related to assets accounted for under the fair value option.

The carrying amount and fair value exclude balances for which the fair value option was elected and obligations under capital leases of $10 million and $11 million at June 30, 2014 and December 31, 2013, respectively.
Loan commitments, standby letters of credit and commercial and similar letters of credit are not included in the table above. A reasonable estimate of the fair value of these instruments is the carrying value of deferred fees plus the related allowance, which totaled $856 million and $597 million at June 30, 2014 and December 31, 2013, respectively.

	We are authorized to issue 20 million shares of preferred stock and 4 million shares of preference stock, both without par value. Preferred shares outstanding rank senior to common shares both as to dividends and liquidation preference but have no general voting rights. We have not issued any preference shares under this authorization. If issued, preference shares would be limited to one vote per share. Our total authorized, issued and outstanding preferred stock is presented in the following two tables.

ESOP Cumulative Convertible Preferred Stock All shares of our ESOP Cumulative Convertible Preferred Stock (ESOP Preferred Stock) were issued to a trustee acting on behalf of the Wells Fargo & Company 401(k) Plan (the 401(k) Plan). Dividends on the ESOP Preferred Stock are cumulative from the date of initial issuance and are payable quarterly at annual rates based upon the year of issuance. Each share of ESOP Preferred Stock released from the unallocated reserve of the 401(k) Plan is converted into shares of our common stock based on the stated value of the ESOP Preferred Stock and the then current market price of our common stock. The ESOP Preferred Stock is also convertible at the option of the holder at any time, unless previously redeemed. We have the option to redeem the ESOP Preferred Stock at any time, in whole or in part, at a redemption price per share equal to the higher of (a) $1,000 per share plus accrued and unpaid dividends or (b) the fair market value, as defined in the Certificates of Designation for the ESOP Preferred Stock.

	We recognize settlement losses for our Cash Balance Plan based on an assessment of whether our estimated lump sum payments related to the Cash Balance Plan will, in aggregate for the year, exceed the sum of its annual service and interest cost (threshold). As of June 30, 2014, it was not considered probable that lump sum payments will exceed this threshold in 2014. In 2013, lump sum payments exceeded this threshold. Settlement losses of $68 million were recognized in second quarter 2013, representing the pro rata portion of the net loss remaining in cumulative other comprehensive income based on the percentage reduction in the Cash Balance Plan's projected benefit obligation. A remeasurement of the Cash Balance liability and related plan assets occurs at the end of each quarter in which settlement losses are recognized.

	Note 18: Operating Segments
	We have three reportable operating segments: Community Banking; Wholesale Banking; and Wealth, Brokerage and Retirement. The results for these operating segments are based on our management accounting process, for which there is no comprehensive, authoritative guidance equivalent to GAAP for financial accounting. The management accounting process measures the performance of the operating segments based on our management structure and is not necessarily comparable with similar information for other financial services companies. We define our operating segments by product type and customer segment. If the management structure and/or the allocation process changes, allocations, transfers and assignments may change. For a complete description of our operating segments, including the underlying management accounting process, see Note 24 (Operating Segments) to Financial Statements in our 2013 Form 10-K.

Regulatory and Agency Capital Requirements [Abstract]	'
Regulatory and Agency Capital Requirements	'
	Note 19: Regulatory and Agency Capital Requirements
	The Company and each of its subsidiary banks are subject to regulatory capital adequacy requirements promulgated by federal bank regulatory agencies. The Federal Reserve establishes capital requirements, including well capitalized standards, for the consolidated financial holding company, and the OCC has similar requirements for the Company's national banks, including Wells Fargo Bank, N.A. (the Bank).
	The following table presents regulatory capital information for Wells Fargo & Company and the Bank. Information presented for June 30, 2014, reflects the transition to Basel III capital requirements from previous regulatory capital adequacy guidelines under Basel I effective in 2013. Among other matters, Basel III revises the definition of capital, and changes will be phased-in effective January 1, 2014, through the end of 2021, with regulatory capital ratios determined using Basel III General Approach risk-weighted assets during 2014. Under the Basel III (General Approach), at June 30, 2014, the Company's Common Equity Tier 1 capital was $134.8 billion, or 11.31% of risk-weighted assets, and the Bank's Common Equity Tier 1 capital was $116.1 billion, or 10.70% of risk-weighted assets.
	We do not consolidate our wholly-owned trust (the Trust) formed solely to issue trust preferred and preferred purchase securities (the Securities). Securities issued by the Trust includable in Tier 2 capital were $2.1 billion at June 30, 2014. During second quarter 2014, we did not redeem any trust preferred securities. Under the new Basel III capital requirements, our remaining trust preferred and preferred purchase securities will begin amortizing in 2016 and will no longer count as Tier 2 capital in 2022.
	The Bank is an approved seller/servicer, and is required to maintain minimum levels of shareholders' equity, as specified by various agencies, including the United States Department of Housing and Urban Development, GNMA, FHLMC and FNMA. At June 30, 2014, the Bank met these requirements. Other subsidiaries, including the Company's insurance and broker-dealer subsidiaries, are also subject to various minimum capital levels, as defined by applicable industry regulations. The minimum capital levels for these subsidiaries, and related restrictions, are not significant to our consolidated operations.

	As defined by the regulations issued by the Federal Reserve, OCC and FDIC.
	The leverage ratio consists of Tier 1 capital divided by quarterly average total assets, excluding goodwill and certain other items. The minimum leverage ratio guideline is 3% for banking organizations that do not anticipate significant growth and that have well-diversified risk, excellent asset quality, high liquidity, good earnings, effective management and monitoring of market risk and, in general, are considered top-rated, strong banking organizations.

Significant Accounting Policies [Line Items]	'
Nature of Operations	'
	Wells Fargo & Company is a diversified financial services company. We provide banking, insurance, trust and investments, mortgage banking, investment banking, retail banking, brokerage, and consumer and commercial finance through banking stores, 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.
Use of Estimates	'
	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, 2013 (2013 Form 10-K). There were no material changes to these policies in the first half of 2014. 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 and 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 and purchased credit-impaired (PCI) loans (Note 5 (Loans and Allowance for Credit Losses)), valuations of residential mortgage servicing rights (MSRs) (Note 7 (Securitizations and Variable Interest Entities) and Note 8 (Mortgage Banking Activities)) and financial instruments (Note 13 (Fair Values of Assets and Liabilities)), liability for mortgage loan repurchase losses (Note 8 (Mortgage Banking Activities)) 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 2013 Form 10-K.
Accounting for Certain Factored Loan Receivable Arrangements	'
	Accounting for Certain Factored Loan Receivable Arrangements
	The Company determined that certain factoring arrangements previously included within commercial loans, which were recorded with a corresponding obligation in other liabilities, did not qualify as loan purchases under Accounting Standard Codification (ASC) Topic 860 (Transfers and Servicing of Financial Assets) based on interpretations of the specific arrangements. Accordingly, we revised our commercial loan balances for year-end 2012 and each of the quarters in 2013 in order to present the Company's lending trends on a comparable basis over this period. This revision, which resulted in a reduction to total commercial loans and a corresponding decrease to other liabilities, did not impact the Company's consolidated net income or total cash flows. We reduced our commercial loans by $3.5 billion, $3.2 billion, $2.1 billion, $1.6 billion, and $1.2 billion at December 31, September 30, June 30 and March 31, 2013, and December 31, 2012, respectively, which represented less than 1% of total commercial loans and less than 0.5% of our total loan portfolio. We also appropriately revised other affected financial information, including financial guarantees and financial ratios, to reflect this revision.
Accounting Standards Adopted in 2014	'
	Accounting Standards Adopted in 2014
	In first quarter 2014, we adopted the following new accounting guidance:
	Accounting Standards Update (ASU or Update) 2014-04, Receivables – Troubled Debt Restructurings by Creditors (Subtopic 310-40) – Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure;
	ASU 2013-11, Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists; and
	ASU 2013-08, Financial Services – Investment Companies (Topic 946): Amendments to the Scope, Measurement and Disclosure Requirements.
Private Share Repurchases	'
	Private Share Repurchases
	From time to time we enter into private forward repurchase transactions with unrelated third parties to complement our open-market common stock repurchase strategies, to allow us to manage our share repurchases in a manner consistent with our capital plans, currently submitted under the 2014 Comprehensive Capital Analysis and Review (CCAR), and to provide an economic benefit to the Company.
	Our payments to the counterparties for these contracts are recorded in permanent equity in the quarter paid and are not subject to re-measurement. The classification of the up-front payments as permanent equity assures that we have appropriate repurchase timing consistent with our 2014 capital plan, which contemplated a fixed dollar amount available per quarter for share repurchases pursuant to Federal Reserve Board (FRB) supervisory guidance. In return, the counterparty agrees to deliver a variable number of shares based on a per share discount to the volume-weighted average stock price over the contract period. There are no scenarios where the contracts would not either physically settle in shares or allow us to choose the settlement method. Our total number of outstanding shares of common stock is not reduced until settlement of the private share repurchase contract.
	In June 2014, we entered into a private forward repurchase contract and paid $1.0 billion to an unrelated third party. This contract settled in July 2014 for 19.5 million shares of common stock. At June 30, 2013, we had a $500 million private repurchase contract outstanding that settled in third quarter 2013 for 12.5 million shares of common stock.
Subsequent Events	'
	Subsequent Events We have evaluated the effects of events that have occurred subsequent to June 30, 2014, and there have been no material events that would require recognition in our second quarter 2014 consolidated financial statements or disclosure in the Notes to the consolidated financial statements.
ASU 2014-04, Receivables: Troubled Debt Restructurings by Creditors: Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosures [Member]	'
Significant Accounting Policies [Line Items]	'
Accounting Standards Adopted in 2014	'
	ASU 2014-04 clarifies the timing of when a creditor is considered to have taken physical possession of residential real estate collateral for a consumer mortgage loan, resulting in the reclassification of the loan receivable to real estate owned. A creditor has taken physical possession of the property when either (1) the creditor obtains legal title through foreclosure, or (2) the borrower transfers all interests in the property to the creditor via a deed in lieu of foreclosure or a similar legal agreement. The Update also requires disclosure of the amount of foreclosed residential real estate property held by the creditor and the recorded investment in residential real estate mortgage loans that are in process of foreclosure. We have included this disclosure through an early adoption of this guidance in first quarter 2014 with prospective application. Our adoption of this guidance did not have a material effect on our consolidated financial statements as this guidance was consistent with our prior practice. See Note 5 (Loans and Allowance for Credit Losses) for the new disclosures.
ASU 2013-11, Income Taxes: Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists [Member]	'
Significant Accounting Policies [Line Items]	'
Accounting Standards Adopted in 2014	'
	ASU 2013-11 eliminates diversity in practice as it provides guidance on financial statement presentation of an unrecognized tax benefit when a net operating loss (NOL) carryforward, a similar tax loss, or a tax credit carryforward exists. We adopted this guidance in first quarter 2014 with prospective application to all unrecognized tax benefits that exist at the effective date. This Update did not have a material effect on our consolidated financial statements.
ASU 2013-08, Financial Services: Investment Companies: Amendments to the Scope, Measurement and Disclosure Requirements [Member]	'
Significant Accounting Policies [Line Items]	'
Accounting Standards Adopted in 2014	'
	ASU 2013-08 amends the scope, measurement and disclosure requirements for investment companies. The Update changes criteria companies use to assess whether an entity is an investment company. In addition, investment companies must measure noncontrolling ownership interests in other investment companies at fair value rather than using the equity method of accounting. This Update also requires new disclosures, including information about changes, if any, in an entity's status as an investment company and information about financial support provided or contractually required to be provided by an investment company to any of its investees. We adopted this guidance in first quarter 2014. The Update did not have a material effect on our consolidated financial statements, as our existing practice complies with the requirements.

	The “Purchases” and “Transfers to MHFS/LHFS" categories exclude activity in government insured/guaranteed real estate 1-4 family first mortgage loans. As servicer, we are able to buy delinquent insured/guaranteed loans out of the Government National Mortgage Association (GNMA) pools. These loans have different risk characteristics from the rest of our consumer portfolio, whereby this activity does not impact the allowance for loan losses in the same manner because the loans are predominantly insured by the Federal Housing Administration (FHA) or guaranteed by the Department of Veterans Affairs (VA). On a net basis, such purchases net of transfers to MHFS were $(1.3) billion and $805 million for the second quarter 2014 and 2013, respectively, and $237 million and $2.8 billion for the first half of 2014 and 2013, respectively.

	Certain impaired loans with an allowance calculated by discounting expected cash flows using the loan's effective interest rate over the remaining life of the loan recognize reductions in the allowance as interest income.
	For PCI loans, charge-offs are only recorded to the extent that losses exceed the purchase accounting estimates.
	The allowance for credit losses includes $8 million and $71 million at June 30, 2014 and 2013, respectively, related to PCI loans acquired from Wachovia. Loans acquired from Wachovia are included in total loans net of related purchase accounting net write-downs.

-1	Amounts represent the recorded investment in loans after recognizing the effects of the TDR, if any. 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 $558 million and $647 million, for quarters ended June 30, 2014 and 2013, and $1.2 billion and $1.6 billion for the first half of 2014 and 2013, respectively.
-2	Principal modifications include principal forgiveness at the time of the modification, contingent principal forgiveness granted over the life of the loan based on borrower performance, and principal that has been legally separated and deferred to the end of the loan, with a zero percent contractual interest rate.
-3	Other concessions include loan renewals, term extensions and other interest and noninterest adjustments, but exclude modifications that also forgive principal and/or reduce the contractual interest rate.
-4	Charge-offs include write-downs of the investment in the loan in the period it is contractually modified. The amount of charge-off will differ from the modification terms if the loan has been charged down prior to the modification based on our policies. In addition, there may be cases where we have a charge-off/down with no legal principal modification. Modifications resulted in legally forgiving principal (actual, contingent or deferred) of $44 million and $95 million for quarters ended June 30, 2014 and 2013, and $92 million and $229 million for the first half of 2014 and 2013, respectively.
-5	Reflects the effect of reduced interest rates on loans with principal or interest rate reduction primary modification type.
-6	Trial modifications are granted a delay in payments due under the original terms during the trial payment period. However, these loans continue to advance through delinquency status and accrue interest according to their original terms. Any subsequent permanent modification generally includes interest rate related concessions; however, the exact concession type and resulting financial effect are usually not known until the loan is permanently modified. Trial modifications for the period are presented net of previously reported trial modifications that became permanent in the current period.

Includes total equity interests of $7.0 billion and $6.9 billion at June 30, 2014, and December 31, 2013, respectively. Also includes debt interests in the form of both loans and securities. Excludes certain debt securities held related to loans serviced for FNMA, FHLMC and GNMA.
Excludes assets and related liabilities with a recorded carrying value on our balance sheet of $1.4 billion and $2.1 billion at June 30, 2014, and December 31, 2013, respectively, for certain delinquent loans that are eligible for repurchase primarily from GNMA loan securitizations. The recorded carrying value represents the amount that would be payable if the Company was to exercise the repurchase option. The carrying amounts are excluded from the table because the loans eligible for repurchase do not represent interests in the VIEs.
Represents senior loans to trusts that are collateralized by asset-backed securities. The trusts invest primarily in senior tranches from a diversified pool of primarily U.S. asset securitizations, of which all are current and 71% and 72% were rated as investment grade by the primary rating agencies at June 30, 2014, and December 31, 2013, respectively. These senior loans are accounted for at amortized cost and are subject to the Company's allowance and credit charge-off policies.
Includes structured financing, auto loan and lease securitizations and credit-linked note structures. Also contains investments in auction rate securities (ARS) issued by VIEs that we do not sponsor and, accordingly, are unable to obtain the total assets of the entity.

	See narrative following this table for a discussion of commercial mortgage servicing rights.
	Prepayment speed assumptions do not significantly impact the value of commercial mortgage securitization bonds as the underlying commercial mortgage loans experience significantly lower prepayments due to certain contractual restrictions, impacting the borrower's ability to prepay the mortgage.
	The prepayment speed assumption for residential mortgage servicing rights includes a blend of prepayment speeds and default rates. Prepayment speed assumptions are influenced by mortgage interest rate inputs as well as our estimation of drivers of borrower behavior.

Beneficiaries (bond trustees) may draw upon these instruments to make scheduled principal and interest payments, redeem all outstanding bonds because a default event has occurred, or for other reasons as permitted by the agreement. We also originate multipurpose lending commitments under which borrowers have the option to draw on the facility in one of several forms, including as a standby letter of credit. Total maximum exposure to loss includes the portion of these facilities for which we have issued standby letters of credit under the commitments.
