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. We also hold a majority interest in a real estate investment trust, which has publicly traded preferred stock outstanding. Our accounting and reporting policies conform with U.S. generally accepted accounting principles (GAAP) and practices in the financial services industry. For discussion of our significant accounting policies, see Note 1 (Summary of Significant Accounting Policies) in our Annual Report on Form 10-K for the year ended December 31, 2015 ( 2015 Form 10-K). There were no material changes to these policies in first quarter 2016 . To prepare the financial statements in conformity with GAAP, management must make estimates based on assumptions about future economic and market conditions (for example, unemployment, market liquidity, real estate prices, etc.) that affect the reported amounts of assets and liabilities at the date of the financial statements, income and expenses during the reporting period and the related disclosures. Although our estimates contemplate current conditions and how we expect them to change in the future, it is reasonably possible that actual conditions could be worse than anticipated in those estimates, which could materially affect our results of operations and financial condition. Management has made significant estimates in several areas, including allowance for credit losses 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)), 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 2015 Form 10-K. Accounting Standards Adopted in 2016 In first quarter 2016 , we adopted the following new accounting guidance: • Accounting Standards Update (ASU or Update) 2015-16 – Business Combinations ( Topic 805 ): Simplifying the Accounting for Measurement-Period Adjustments; • ASU 2015-07 – Fair Value Measurement (Topic 820): Disclosures for Investments in Certain Entities that Calculate Net Asset Value per Share (or Its Equivalent); • ASU 2015-03 – Interest – Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs; • ASU 2015-02 – Consolidation (Topic 810): Amendments to the Consolidation Analysis; • ASU 2015-01 – Income Statement – Extraordinary and Unusual Items (Subtopic 225-20): Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items; • ASU 2014-16 – Derivatives and Hedging (Topic 815): Determining Whether the Host Contract in a Hybrid Financial Instrument Issued in the Form of a Share is More Akin to Debt or to Equity; • ASU 2014-13 – Consolidation (Topic 810): Measuring the Financial Assets and the Financial Liabilities of a Consolidated Collateralized Financing Entity; and • ASU 2014-12 – Compensation – Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period. ASU 2015-16 eliminates the requirement for companies to retrospectively adjust initial amounts recognized in business combinations when the accounting is incomplete at the acquisition date. Under the new guidance, companies should record adjustments in the same reporting period in which the amounts are determined. We adopted this accounting change in first quarter 2016 with prospective application. The Update did not have a material impact on our consolidated financial statements. ASU 2015-07 eliminates the disclosure requirement to categorize investments within the fair value hierarchy that are measured at fair value using net asset value as a practical expedient. We adopted this change in first quarter 2016 with retrospective application. The Update did not affect our consolidated financial statements as it impacts only the fair value disclosure requirements for certain investments. For additional information, see Note 13 (Fair Values of Assets and Liabilities). ASU 2015-03 changes the balance sheet presentation for debt issuance costs. Under the new guidance, debt issuance costs should be reported as a deduction from debt liabilities rather than as a deferred charge classified as an asset. We adopted this change in first quarter 2016, which resulted in a $180 million reclassification from Other assets to Long-term debt on January 1, 2016. Because the impact on prior periods was not material, we applied the guidance prospectively. ASU 2015-02 requires companies to reevaluate all legal entities under new consolidation guidance. The new guidance primarily amends the criteria companies use to evaluate whether they should consolidate certain variable interest entities that have fee arrangements and the criteria used to determine whether partnerships and similar entities are variable interest entities. The new guidance also amends the consolidation analysis for certain investment funds and excludes certain money market funds. We adopted the accounting changes on January 1, 2016, which resulted in a net increase in assets and a corresponding cumulative-effect adjustment to noncontrolling interests of $121 million . There was no impact to consolidated retained earnings. For additional information, see Note 7 (Securitizations and Variable Interest Entities). ASU 2015-01 removes the concept of extraordinary items from GAAP and eliminates the requirement for extraordinary items to be separately presented in the statement of income. We adopted this change in first quarter 2016 with prospective application. This Update did not have a material impact on our consolidated financial statements. ASU 2014-16 clarifies that the nature of host contracts in hybrid financial instruments that are issued in share form should be determined based on the entire instrument, including the embedded derivative. We adopted this new requirement in first quarter 2016. This Update did not have a material impact on our consolidated financial statements. ASU 2014-13 provides a measurement alternative to companies that consolidate collateralized financing entities (CFEs), such as collateralized debt obligation and collateralized loan obligation structures. Under the new guidance, companies can measure both the financial assets and financial liabilities of a CFE using the more observable fair value of the financial assets or of the financial liabilities. We adopted this accounting change in first quarter 2016. The Update did not have a material impact on our consolidated financial statements. ASU 2014-12 provides accounting guidance for employee share-based payment awards with specific performance targets. The Update clarifies that performance targets should be treated as performance conditions if the targets affect vesting and could be achieved after the requisite service period. We adopted this change in first quarter 2016 with prospective application. The Update did not have a material effect on our consolidated financial statements, as our historical practice complies with the new 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 2015 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 2015 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. We had no unsettled private share repurchase contracts at March 31, 2016 . At March 31, 2015 , we had a $750 million private repurchase contract outstanding that settled in April 2015 for 14.0 million shares of common stock. SUPPLEMENTAL CASH FLOW INFORMATION Significant noncash activities are presented below. Table 1.1: Supplemental Cash Flow Information Quarter ended March 31, (in millions) 2016 2015 Trading assets retained from securitization of MHFS $ 9,955 6,874 Transfers from loans to MHFS 1,839 2,202 Transfers from available-for-sale to held-to-maturity securities — 4,972 SUBSEQUENT EVENTS We have evaluated the effects of events that have occurred subsequent to March 31, 2016 , and there have been no material events that would require recognition in our first quarter 2016 consolidated financial statements or disclosure in the Notes to the consolidated financial statements.

Business Combinations [Abstract]
Business Combinations	Note 2: Business Combinations We regularly explore opportunities to acquire financial services companies and businesses. Generally, we do not make a public announcement about an acquisition opportunity until a definitive agreement has been signed. For information on additional contingent consideration related to acquisitions, which is considered to be a guarantee, see Note 10 (Guarantees, Pledged Assets and Collateral). During first quarter 2016, we completed two acquisitions. On January 1, 2016 , we acquired $4.4 billion in assets associated with GE Railcar Services, which included 77,000 railcars and 1,000 locomotives. The acquired assets included $918 million of loans and capital leases and $3.2 billion of operating lease assets. On March 1, 2016 , we acquired $29.9 billion in assets associated with the North American portion of GE Capital’s Commercial Distribution Finance and Vendor Finance businesses. The acquired assets included $24.0 billion of loans and capital leases, $2.7 billion of operating lease assets, and $2.3 billion of goodwill and identifiable intangible assets. The North American portion represented approximately 90% of the total assets to be acquired. The international portion is expected to close during the second half of 2016. On March 31, 2016 , we completed the divestiture of Rural Community Insurance, our crop insurance business. The transaction involved the sale of approximately $4 billion in assets which resulted in a pre-tax gain of $381 million .

Federal Funds Sold, Securities Purchased under Resale Agreements and Other Short-Term Investments	Note 3: Federal Funds Sold, Securities Purchased under Resale Agreements and Other Short-Term Investments Table 3.1 provides the detail of federal funds sold, securities purchased under short-term resale agreements (generally less than one year) and other short-term investments. The majority of interest-earning deposits at March 31, 2016 , and December 31, 2015 , were held at the Federal Reserve. Table 3.1: Fed Funds Sold and Other Short-Term Investments (in millions) Mar 31, Dec 31, Federal funds sold and securities purchased under resale agreements $ 49,698 45,828 Interest-earning deposits 242,754 220,409 Other short-term investments 8,095 3,893 Total $ 300,547 270,130 As part of maintaining our memberships in certain clearing organizations, we are required to stand ready to provide liquidity meant to sustain market clearing activity in the event unforeseen events occur or are deemed likely to occur. This includes commitments we have entered into to purchase securities under resale agreements from a central clearing organization that, at its option, require us to provide funding under such agreements. We do not have any outstanding amounts funded, and the amount of our unfunded contractual commitment was $2.6 billion and $2.2 billion as of March 31, 2016 , and December 31, 2015 , respectively. We have classified securities purchased under long-term resale agreements (generally one year or more), which totaled $21.1 billion and $20.1 billion at March 31, 2016 , and December 31, 2015 , respectively, in loans. For additional information on the collateral we receive from other entities under resale agreements and securities borrowings, see the “Offsetting of Resale and Repurchase Agreements and Securities Borrowing and Lending Agreements” section in Note 10 (Guarantees, Pledged Assets and Collateral).

Investments, Debt and Equity Securities [Abstract]
Investment Securities	Note 4: Investment Securities Table 4.1 provides the amortized cost and fair value by major categories of available-for-sale securities, which are carried at fair value, and held-to-maturity debt securities, which are carried at amortized cost. The net unrealized gains (losses) for available-for-sale securities are reported on an after-tax basis as a component of cumulative OCI.

(2) The “Other” category of available-for-sale securities largely includes asset-backed securities collateralized by credit cards, student loans, home equity loans and auto leases or loans and cash. Included in the “Other” category of held-to-maturity securities are asset-backed securities collateralized by auto leases or loans and cash with a cost basis and fair value of $1.6 billion each at March 31, 2016 , and $1.9 billion each at December 31, 2015 . Also included in the “Other” category of held-to-maturity securities are asset-backed securities collateralized by dealer floorplan loans with a cost basis and fair value of $1.5 billion each at March 31, 2016 , and $1.4 billion each at December 31, 2015 . Gross Unrealized Losses and Fair Value Table 4.2 shows the gross unrealized losses and fair value of securities in the investment securities portfolio by length of time that individual securities in each category have been in a continuous loss position. Debt securities on which we have taken credit-related OTTI write-downs are categorized as being “less than 12 months” or “12 months or more” in a continuous loss position based on the point in time that the fair value declined to below the cost basis and not the period of time since the credit-related OTTI write-down.

As part of that assessment we evaluated and concluded that we do not intend to sell any of the securities and that it is more likely than not that we will not be required to sell prior to recovery of the amortized cost basis. 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 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 2015 Form 10-K. There have been no material changes to our methodologies for assessing impairment in first quarter 2016 . Table 4.3 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 our 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 $24 million and $4.8 billion , respectively, at March 31, 2016 , and $17 million and $3.7 billion , respectively, at December 31, 2015 . If an internal credit grade was not assigned, we categorized the security as non-investment grade.

The remaining contractual principal maturities for MBS do not consider prepayments. Remaining expected maturities will differ from contractual maturities because borrowers may have the right to prepay obligations before the underlying mortgages mature.

Loans and Allowance for Credit Losses	Note 5: Loans and Allowance for Credit Losses Table 5.1 presents total loans outstanding by portfolio segment and class of financing receivable. Outstanding balances include a total net reduction of $5.3 billion and $3.8 billion at March 31, 2016 , and December 31, 2015 , respectively, for unearned income, net deferred loan fees, and unamortized discounts and premiums. Outstanding balances at March 31, 2016 also reflect the acquisition of various loans and capital leases from GE Capital as described in Note 2 (Business Combinations). Table 5.1: Loans Outstanding (in millions) Mar 31, Dec 31, Commercial: Commercial and industrial $ 321,547 299,892 Real estate mortgage 124,711 122,160 Real estate construction 22,944 22,164 Lease financing 19,003 12,367 Total commercial 488,205 456,583 Consumer: Real estate 1-4 family first mortgage 274,734 273,869 Real estate 1-4 family junior lien mortgage 51,324 53,004 Credit card 33,139 34,039 Automobile 60,658 59,966 Other revolving credit and installment 39,198 39,098 Total consumer 459,053 459,976 Total loans $ 947,258 916,559 Our foreign loans are reported by respective class of financing receivable in the table above. 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. Table 5.2 presents total commercial foreign loans outstanding by class of financing receivable. Table 5.2: Commercial Foreign Loans Outstanding (in millions) Mar 31, Dec 31, Commercial foreign loans: Commercial and industrial $ 51,884 49,049 Real estate mortgage 8,367 8,350 Real estate construction 311 444 Lease financing 983 274 Total commercial foreign loans $ 61,545 58,117 Loan Purchases, Sales, and Transfers Table 5.3 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 for which we have elected the fair value option, including loans originated for sale because their loan activity normally does not impact the allowance for credit losses. Table 5.3: Loan Purchases, Sales, and Transfers Quarter ended March 31, 2016 2015 (in millions) Commercial Consumer Total Commercial Consumer Total Purchases (1)(2) $ 24,646 — 24,646 1,091 — 1,091 Sales (1) (223 ) (272 ) (495 ) (206 ) (29 ) (235 ) Transfers to MHFS/LHFS (1) (32 ) (3 ) (35 ) (7 ) (2 ) (9 ) (1) All 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, and manage and/or resell them in accordance with applicable requirements. These loans are predominantly insured by the Federal Housing Administration (FHA) or guaranteed by the Department of Veterans Affairs (VA). Accordingly, these loans have limited impact on the allowance for loan losses. (2) Purchases in first quarter 2016 include loans and capital leases from the GE Capital acquisitions as described in Note 2 (Business Combinations). 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 $77 billion at March 31, 2016 and $75 billion at December 31, 2015 . We issue commercial letters of credit to assist customers in purchasing goods or services, typically for international trade. At March 31, 2016 , and December 31, 2015 , we had $1.2 billion and $1.1 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 Table 5.4 . The table excludes the standby and commercial letters of credit and temporary advance arrangements described above.

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).We obtain FICO scores at loan origination and the scores are generally updated at least quarterly, except in limited circumstances, including compliance with the Fair Credit Reporting Act (FCRA). Generally, the LTV and CLTV indicators are updated in the second month of each quarter, with updates no older than December 31, 2015 . See the “Purchased Credit-Impaired Loans” section in 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. Table 5.8 provides a breakdown of outstanding commercial loans by risk category. Of the $6.7 billion in criticized commercial real estate (CRE) loans at March 31, 2016 , $1.0 billion has been placed on nonaccrual status and written down to net realizable collateral value.

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. Table 5.10 provides the outstanding balances of our consumer portfolio by delinquency status.

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. Table 5.12 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.

PCI loans are excluded from this table because they continue to earn interest from accretable yield, independent of performance in accordance with their contractual terms.

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 $10.3 billion and $11.0 billion at March 31, 2016 and December 31, 2015 , respectively, which included $5.7 billion and $6.2 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 $2.7 billion at March 31, 2016 , and $2.9 billion at December 31, 2015 , 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. Table 5.14 shows non-PCI loans 90 days or more past due and still accruing by class for loans not government insured/guaranteed.

(3) Represents loans whose repayments are predominantly guaranteed by agencies on behalf of the U.S. Department of Education under the FFELP. IMPAIRED LOANS Table 5.15 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. Table 5.15 includes trial modifications that totaled $380 million at March 31, 2016 , and $402 million at December 31, 2015 . For additional information on our impaired loans and allowance for credit losses, see Note 1 (Summary of Significant Accounting Policies) in our 2015 Form 10-K.

(2) Periods ended March 31, 2016 and December 31, 2015 each include the recorded investment of $1.8 billion of government insured/guaranteed loans that are predominantly insured by the FHA or guaranteed by the VA and generally do not have an allowance. Impaired loans may also have limited, if any, allowance when the recorded investment of the loan approximates estimated net realizable value as a result of charge-offs prior to a TDR modification. Commitments to lend additional funds on loans whose terms have been modified in a TDR amounted to $364 million and $363 million at March 31, 2016 and December 31, 2015 , respectively. Table 5.16 provides the average recorded investment in impaired loans and the amount of interest income recognized on impaired loans by portfolio segment and class.

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 March 31, 2016 , the loans in trial modification period were $143 million under HAMP, $32 million under 2MP and $205 million under proprietary programs, compared with $130 million , $32 million and $240 million at December 31, 2015 , respectively. Trial modifications with a recorded investment of $129 million at March 31, 2016 , and $136 million at December 31, 2015 , were accruing loans and $251 million and $266 million , respectively, were nonaccruing loans. Our experience is that substantially all 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 i

Table 6.2: Nonmarketable Equity Investments Quarter ended March 31, (in millions) 2016 2015 Net realized gains from nonmarketable equity investments $ 185 351 All other (186 ) (148 ) Total $ (1 ) 203 Low Income Housing Tax Credit Investments We invest in affordable housing projects that qualify for the low income housing tax credit (LIHTC), which is designed to promote private development of low income housing. These investments generate a return primarily through realization of federal tax credits. Total LIHTC investments were $8.6 billion and $8.3 billion at March 31, 2016 and December 31, 2015 , respectively. In first quarter 2016 , we recognized pre-tax losses of $202 million related to our LIHTC investments, compared with $178 million in first quarter 2015. We also recognized total tax benefits of $307 million in first quarter 2016 and $276 million in first quarter 2015, which included tax credits of $230 million and $209 million for the same periods, respectively, recorded in income taxes. We are periodically required to provide additional financial support during the investment period. Our liability for these unfunded commitments was $3.2 billion at March 31, 2016 and $3.0 billion at December 31, 2015 . Predominantly all of this liability is expected to be paid over the next three years. This liability is included in long-term debt.

Securitizations and Variable Interest Entities [Abstract]
Securitizations and Variable Interest Entities	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 SPEs, which are corporations, trusts, limited liability companies 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 2015 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. Table 7.1 provides the classifications of assets and liabilities in our balance sheet for our transactions with VIEs. Table 7.1: Balance Sheet Transactions with VIEs (in millions) VIEs that we do not consolidate VIEs that we consolidate Transfers that we account for as secured borrowings Total March 31, 2016 Cash $ — 288 — 288 Trading assets 1,269 152 203 1,624 Investment securities (1) 11,512 372 1,506 13,390 Loans 8,851 13,865 4,619 27,335 Mortgage servicing rights 11,547 — — 11,547 Other assets 9,194 518 16 9,728 Total assets 42,373 15,195 6,344 63,912 Short-term borrowings — — 1,458 1,458 Accrued expenses and other liabilities 588 146 (2) 1 735 Long-term debt 3,151 4,731 (2) 4,569 12,451 Total liabilities 3,739 4,877 6,028 14,644 Noncontrolling interests — 202 — 202 Net assets $ 38,634 10,116 316 49,066 December 31, 2015 Cash $ — 157 — 157 Trading assets 1,340 1 203 1,544 Investment securities (1) 12,388 425 2,171 14,984 Loans 9,661 4,811 4,887 19,359 Mortgage servicing rights 12,518 — — 12,518 Other assets 8,938 242 26 9,206 Total assets 44,845 5,636 7,287 57,768 Short-term borrowings — — 1,799 1,799 Accrued expenses and other liabilities 629 57 (2) 1 687 Long-term debt 3,021 1,301 (2) 4,844 9,166 Total liabilities 3,650 1,358 6,644 11,652 Noncontrolling interests — 93 — 93 Net assets $ 41,195 4,185 643 46,023 (1) Excludes certain debt securities related to loans serviced for the Federal National Mortgage Association (FNMA), Federal Home Loan Mortgage Corporation (FHLMC) and GNMA. (2) There were no VIE liabilities with recourse to the general credit of Wells Fargo for the periods presented. Transactions with Unconsolidated VIEs Our transactions with unconsolidated VIEs include securitizations of residential mortgage loans, CRE loans, student loans, auto loans and leases, certain dealer floorplan loans; investment and financing activities involving collateralized debt obligations (CDOs) backed by asset-backed and CRE securities, tax credit structures, collateralized loan obligations (CLOs) backed by corporate loans, and other types of structured financing. We have various forms of involvement with VIEs, including servicing, 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, other liabilities, and long-term debt, as appropriate. Table 7.2 provides 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 (unless we are servicer and have other significant forms of involvement) or if we were the sponsor only or sponsor and servicer but do not have any other forms of significant 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 (other than those held temporarily in 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 of the unconsolidated VIEs. We also exclude from the table secured borrowing transactions with unconsolidated VIEs (for information on these transactions, see the Transactions with Consolidated VIEs and Secured Borrowings section in this Note).

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. (2) Excludes assets and related liabilities with a recorded carrying value on our balance sheet of $938 million and $1.3 billion at March 31, 2016 , and December 31, 2015 , 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. (3) 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 70% were rated as investment grade by the primary rating agencies at March 31, 2016 , and December 31, 2015 , respectively. These senior loans are accounted for at amortized cost and are subject to the Company’s allowance and credit charge-off policies. (4) Includes structured financing 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 2015 Form 10-K. INVESTMENT FUNDS In first quarter 2016, we adopted ASU 2015-02 ( Amendments to the Consolidation Analysis ) which changed the consolidation analysis for certain investment funds. We do not consolidate these investment funds because we do not hold variable interests that are considered significant to the funds. We voluntarily waived a portion of our management fees for certain money market funds that are exempt from the consolidation analysis to ensure the funds maintained a minimum level of daily net investment income. The amount of fees waived was $30 million and $56 million in first quarter 2016 and 2015 , respectively. OTHER TRANSACTIONS WITH VIEs Other VIEs include certain entities that issue auction rate securities (ARS) which are debt instruments with long-term maturities, that re-price more frequently, and preferred equities with no maturity. At March 31, 2016 , we held $473 million of ARS issued by VIEs compared with $502 million at December 31, 2015 . We acquired the ARS pursuant to agreements entered into in 2008 and 2009. 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 March 31, 2016 , and December 31, 2015 , we reported the debt securities issued to the VIEs as long-term junior subordinated debt with a carrying value of $2.2 billion , 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. Loan Sales and Securitization Activity We periodically transfer consumer and CRE loans and other types of financial assets in securitization and whole loan sale transactions. We typically retain the servicing rights from these sales and may continue to hold other beneficial interests in the transferred financial assets. We may also provide liquidity to investors in the beneficial interests and credit enhancements in the form of standby letters of credit. Through these transfers we may be exposed to liability under limited amounts of recourse as well as standard representations and warranties we make to purchasers and issuers. Table 7.3 presents the cash flows for our transfers accounted for as sales. Table 7.3: Cash Flows From Sales and Securitization Activity 2016 2015 (in millions) Mortgage loans Other financial assets Mortgage loans Other financial assets Quarter ended March 31, Proceeds from securitizations and whole loan sales $ 45,016 50 41,909 21 Fees from servicing rights retained 881 — 935 2 Cash flows from other interests held (1) 407 1 266 12 Repurchases of assets/loss reimbursements (2): Non-agency securitizations and whole loan transactions 3 — 6 — Agency securitizations (3) 47 — 62 — Servicing advances, net of repayments (68 ) — (100 ) — (1) Cash flows from other interests held include principal and interest payments received on retained bonds and excess cash flows received on interest-only strips. (2) Consists of cash paid to repurchase loans from investors and cash paid to investors to reimburse them for losses on individual loans that are already liquidated. (3) Represent loans repurchased from GNMA, FNMA, and FHLMC under representation and warranty provisions included in our loan sales contracts. First quarter 2016 and 2015 exclude $ 2.9 billion and $ 3.3 billion , respectively, in delinquent insured/guaranteed loans that we service and have exercised our option to purchase out of GNMA pools. These loans are predominantly insured by the FHA or guaranteed by the VA. In first quarter 2016 and 2015 , we recognized net gains of $195 million and $111 million , respectively, from transfers accounted for as sales of financial assets. 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 first quarter 2016 and 2015 primarily 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 first quarter 2016 and 2015 , we transferred $37.3 billion and $39.5 billion , respectively, in fair value of residential mortgages to unconsolidated VIEs and third-party investors and recorded the transfers as sales. 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 first quarter 2016 , we recorded a $315 million servicing asset, measured at fair value using a Level 3 measurement technique, securities of $832 million , classified as Level 2, and a $7 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 first quarter 2015 , we recorded a $308 million servicing asset, securities of $517 million , and a $10 million liability. Table 7.4 presents the key weighted-average assumptions we used to measure residential mortgage servicing rights at the date of securitization. Table 7.4: Residential Mortgage Servicing Rights Residential mortgage servicing rights 2016 2015 Quarter ended March 31, Prepayment speed (1) 13.0 % 13.0 Discount rate 6.8 7.5 Cost to service ($ per loan) (2) $ 146 237 (1) 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. (2) Includes costs to service and unreimbursed foreclosure costs, which can vary period to period depending on the mix of modified government-guaranteed loans sold to GNMA. During first quarter 2016 and 2015 , we transferred $8.1 billion and $3.2 billion , respectively, in carrying value of commercial mortgages to unconsolidated VIEs and third-party investors and recorded the transfers as sales. These transfers resulted in gains of $135 million and $77 million for the same periods, respectively, because the loans were carried at lower of cost or market value (LOCOM). In connection with these transfers, in first quarter 2016 , we recorded a servicing asset of $97 million , initially measured at fair value using a Level 3 measurement technique, and securities of $86 million , classified as Level 2. In first quarter 2015 , we recorded a servicing asset of $50 million . Retained Interests from Unconsolidated VIEs Table 7.5 provides key economic assumptions and the sensitivity of the current fair value of residential mortgage servicing rights and other interests held 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.

(2) 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. (3) 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 $1.7 billion at both March 31, 2016 , and December 31, 2015 . 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 March 31, 2016 , and December 31, 2015 , results in a decrease in fair value of $145 million and $150 million , respectively. See Note 8 (Mortgage Banking Activities) for further information on our commercial MSRs. We also have a loan to an unconsolidated third party VIE that we extended in fourth quarter 2014 in conjunction with our sale of government guaranteed student loans. The loan is carried at amortized cost and approximates fair value at March 31, 2016 , and December 31, 2015 . The carrying amount of the loan at March 31, 2016 , and December 31, 2015 , was $4.7 billion and $4.9 billion , respectively. The estimated fair value of the loan is considered a Level 3 measurement that is determined using discounted cash flows that are based on changes in the discount rate due to changes in the risk premium component (credit spreads). The primary economic assumption impacting the fair value of our loan is the discount rate. Changes in the credit loss assumption are not expected to affect the estimated fair value of the loan due to the government guarantee of the underlying collateral. The sensitivity of the current fair value to an immediate adverse increase of 200 basis points in the risk premium component of the discount rate assumption is a decrease in fair value of $119 million and $82 million at March 31, 2016 , and December 31, 2015 , respectively. The sensitivities in the preceding paragraphs 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. Off-Balance Sheet Loans Table 7.6 presents information about the principal balances of off-balance sheet loans that were sold or securitized, including residential mortgage loans sold to FNMA, FHLMC, GNMA and other investors, for which we have some form of continuing involvement (primarily servicer). Delinquent loans include loans 90 days or more past due and loans in bankruptcy, regardless of delinquency status. For loans sold or securitized where servicing is our only form of continuing involvement, we would only experience a loss if we were required to repurchase a delinquent loan or foreclosed asset due to a breach in representations and warranties associated with our loan sale or servicing contracts.

(2) At March 31, 2016 , and December 31, 2015 , the table includes total loans of $1.2 trillion at both dates, delinquent loans of $10.9 billion and $12.1 billion , and foreclosed assets of $1.6 billion and $1.7 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 Table 7.7 presents a summary of financial assets and liabilities for asset transfers accounted for as secured borrowings and involvements with consolidated VIEs. “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. Table 7.7: Transactions with Consolidated VIEs and Secured Borrowings Carrying value (in millions) Total VIE assets Assets Liabilities Noncontrolling interests Net assets March 31, 2016 Secured borrowings: Municipal tender option bond securitizations $ 2,206 1,725 (1,459 ) — 266 Residential mortgage securitizations 4,473 4,619 (4,569 ) — 50 Total secured borrowings 6,679 6,344 (6,028 ) — 316 Consolidated VIEs: Commercial and industrial loans and leases 9,532 9,532 (3,502 ) (11 ) 6,019 Nonconforming residential mortgage loan securitizations 3,936 3,500 (1,186 ) — 2,314 Commercial real estate loans 1,195 1,195 — — 1,195 Structured asset finance 49 18 (15 ) — 3 Investment funds (1) 679 679 (73 ) (115 ) 491 Other 283 271 (101 ) (76 ) 94 Total consolidated VIEs 15,674 15,195 (4,877 ) (202 ) 10,116 Total secured borrowings and consolidated VIEs $ 22,353 21,539 (10,905 ) (202 ) 10,432 December 31, 2015 Secured borrowings: Municipal tender option bond securitizations $ 2,818 2,400 (1,800 ) — 600 Residential mortgage securitizations 4,738 4,887 (4,844 ) — 43 Total secured borrowings 7,556 7,287 (6,644 ) — 643 Consolidated VIEs: Nonconforming residential mortgage loan securitizations 4,134 3,654 (1,239 ) — 2,415 Commercial real estate loans 1,185 1,185 — — 1,185 Structured asset finance 54 20 (18 ) — 2 Investment funds 482 482 — — 482 Other 305 295 (101 ) (93 ) 101 Total consolidated VIEs 6,160 5,636 (1,358 ) (93 ) 4,185 Total secured borrowings and consolidated VIEs $ 13,716 12,923 (8,002 ) (93 ) 4,828 (1) Includes investment funds with total VIE assets of $265 million that were considered consolidated VIEs effective January 1, 2016, pursuant to our adoption of ASU 2015-02 ( Amendments to the Consolidation Analysis). COMMERCIAL AND INDUSTRIAL LOANS AND LEASES In conjunction with the GE Capital transactions, on March 1, 2016, we acquired certain consolidated SPE entities. The most significant of these SPEs is a revolving master trust entity that purchases dealer floorplan loans and issues senior and subordinated notes. The senior notes are held by third parties and the subordinated notes and residual equity interests are held by us. At March 31, 2016, total assets held by the master trust were $7.9 billion and the outstanding senior notes were $3.2 billion . The other SPEs acquired include securitization term trust entities, which purchase vendor finance lease and loan assets and issue notes to investors, and a SPE that engages in leasing activities to specific vendors. At March 31, 2016, total assets held by these SPEs were $1.6 billion , with outstanding debt of $261 million . We are the primary beneficiary of these acquired SPEs due to our ability to direct the most significant activities of the SPEs, primarily through our role as servicer, and because we hold variable interests that are considered significant. INVESTMENT FUNDS Our adoption of ASU 2015-02 ( Amendments to the Consolidation Analysis ) changed the consolidation analysis for certain investment funds. We consolidate certain investment funds because we have both the power to manage fund assets and hold variable interests that are considered significant. OTHER CONSOLIDATED VIE STRUCTURES In addition to the structure types included in the previous table, at both March 31, 2016 , and December 31, 2015 , 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 March 31, 2016 , we pledged approximately $505 million in loans (principal and interest eligible to be capitalized) and $5.9 billion in available-for-sale securities to collateralize the VIE’s borrowings, compared with $529 million and $5.9 billion , respectively, at December 31, 2015 . 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 2015 Form 10-K.

Mortgage Banking Activities [Abstract]
Mortgage Banking Activities	Note 8: Mortgage Banking Activities Mortgage banking activities, included in the Community Banking and Wholesale Banking operating segments, consist of residential and commercial mortgage originations, sale activity and servicing. We apply the amortization method to commercial MSRs and apply the fair value method to residential MSRs. Table 8.1 presents the changes in MSRs measured using the fair value method. Table 8.1: Analysis of Changes in Fair Value MSRs Quarter ended March 31, (in millions) 2016 2015 Fair value, beginning of period $ 12,415 12,738 Servicing from securitizations or asset transfers (1) 366 308 Sales and other (2) — (1 ) Net additions 366 307 Changes in fair value: Due to changes in valuation model inputs or assumptions: Mortgage interest rates (3) (1,084 ) (572 ) Servicing and foreclosure costs (4) 27 (18 ) Prepayment estimates and other (5) 100 (183 ) Net changes in valuation model inputs or assumptions (957 ) (773 ) Other changes in fair value (6) (491 ) (533 ) Total changes in fair value (1,448 ) (1,306 ) Fair value, end of period $ 11,333 11,739 (1) Includes impacts associated with exercising our right to repurchase delinquent loans from GNMA loan securitization pools. (2) Includes sales and transfers of MSRs. (3) Includes prepayment speed changes as well as other valuation changes due to changes in mortgage interest rates (such as changes in estimated interest earned on custodial deposit balances). (4) Includes costs to service and unreimbursed foreclosure costs. (5) Represents changes driven by other valuation model inputs or assumptions including prepayment speed estimation changes and other assumption updates. Prepayment speed estimation changes are influenced by observed changes in borrower behavior and other external factors that occur independent of interest rate changes. (6) Represents changes due to collection/realization of expected cash flows over time. Table 8.2 presents the changes in amortized MSRs. Table 8.2: Analysis of Changes in Amortized MSRs Quarter ended March 31, (in millions) 2016 2015 Balance, beginning of period $ 1,308 1,242 Purchases 21 22 Servicing from securitizations or asset transfers 97 50 Amortization (67 ) (62 ) Balance, end of period (1) $ 1,359 1,252 Fair value of amortized MSRs: Beginning of period $ 1,680 1,637 End of period 1,725 1,522 (1) Commercial amortized MSRs are evaluated for impairment purposes by the following risk strata: agency (GSEs) and non-agency. There was no valuation allowance recorded for the periods presented on the commercial amortized MSRs. We present the components of our managed servicing portfolio in Table 8.3 at unpaid principal balance for loans serviced and subserviced for others and at book value for owned loans serviced.

(2) Refer to the changes in fair value of MSRs table in this Note for more detail. (3) Represents changes due to collection/realization of expected cash flows over time. (4) Represents results from economic hedges used to hedge the risk of changes in fair value of MSRs. See Note 12 (Derivatives Not Designated as Hedging Instruments) for additional discussion and detail. Table 8.5 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 exceeded our recorded liability by $274 million at March 31, 2016 , and was determined based upon modifying the assumptions (particularly to assume significant changes in investor repurchase demand practices) used in our best estimate of probable loss to reflect what we believe to be the high end of reasonably possible adverse assumptions.

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 2015 Form 10-K.

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. (2) Includes indemnifications provided to certain third-party clearing agents. Outstanding customer obligations under these arrangements were $208 million and $352 million with related collateral of $952 million and $1.5 billion at March 31, 2016 , and December 31, 2015 , respectively. Estimated maximum exposure to loss was $1.2 billion and $1.8 billion as of the same periods, respectively. (3) Written put options, which are in the form of derivatives, are also included in the derivative disclosures in Note 12 (Derivatives). (4) Represent recourse provided, predominantly to the GSEs, on loans sold under various programs and arrangements. Under these arrangements, we repurchased $1 million of loans associated with these agreements in both first quarter 2016 and 2015 . (5) 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. “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), securities lending arrangements, 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. Table 10.2 provides the total carrying amount of pledged assets by asset type. The table excludes pledged consolidated VIE assets of $15.2 billion and $5.6 billion at March 31, 2016 , and December 31, 2015 , respectively, which can only be used to settle the liabilities of those entities. The table also excludes $6.3 billion and $7.3 billion in assets pledged in transactions accounted for as secured borrowings at March 31, 2016 , and December 31, 2015 , respectively. See Note 7 (Securitizations and Variable Interest Entities) for additional information on consolidated VIE assets and secured borrowings.

(2) Includes carrying value of $5.5 billion and $6.5 billion (fair value of $5.5 billion and $ 6.5 billion ) in collateral for repurchase agreements at March 31, 2016 , and December 31, 2015 , respectively, which are pledged under agreements that do not permit the secured parties to sell or repledge the collateral. Also includes $12.9 billion and $13.0 billion in collateral pledged under repurchase agreements at March 31, 2016 , and December 31, 2015 , respectively, that permit the secured parties to sell or repledge the collateral. Substantially all other pledged securities are pursuant to agreements that do not permit the secured party to sell or repledge the collateral. (3) Includes mortgages held for sale of $9.9 billion and $8.7 billion at March 31, 2016 , and December 31, 2015 , respectively. Balance consists of mortgages held for sale and loans that are pledged under agreements that do not permit the secured parties to sell or repledge the collateral. Amounts exclude $938 million and $1.3 billion at March 31, 2016 , and December 31, 2015 , 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. Securities Financing Activities We enter into resale and repurchase agreements and securities borrowing and lending agreements (collectively, “securities financing activities”) primarily to finance inventory positions, acquire securities to cover short trading positions, accommodate customers’ financing needs, and settle other securities obligations. These activities are conducted through our broker dealer subsidiaries and to a lesser extent through other bank entities. The majority of our securities financing activities involve high quality, liquid securities such as U.S. Treasury securities and government agency securities, and to a lesser extent, less liquid securities, including equity securities, corporate bonds and asset-backed securities. We account for these transactions as collateralized financings in which we typically receive or pledge securities as collateral. We believe these financing transactions generally do not have material credit risk given the collateral provided and the related monitoring processes. OFFSETTING OF RESALE AND REPURCHASE AGREEMENTS AND SECURITIES BORROWING AND LENDING AGREEMENTS Table 10.3 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 liability. Collateral we received includes securities or loans and is not recognized on our balance sheet. Collateral pledged or received may be increased or decreased over time to maintain certain contractual thresholds as the assets underlying each arrangement fluctuate in value. Generally, these agreements require collateral to exceed the asset or liability recognized on the balance sheet. The following table includes the amount of collateral pledged or received related to exposures subject to enforceable MRAs or MSLAs. While these agreements are typically over-collateralized, U.S. GAAP requires disclosure in this table to limit the amount of such collateral to the amount of the related recognized asset or liability for each counterparty. In addition to the amounts included in Table 10.3 , we also have balance sheet netting related to derivatives that is disclosed in Note 12 (Derivatives).

These amounts include securities we have sold or repledged to others with a fair value of $57.8 billion at March 31, 2016 , and $51.1 billion at December 31, 2015 . (4) Represents the amount of our exposure that is not collateralized and/or is not subject to an enforceable MRA or MSLA.

At March 31, 2016 , and December 31, 2015 , we have pledged total collateral with a fair value of $105.9 billion and $92.9 billion , respectively, of which, the counterparty does not have the right to sell or repledge $6.0 billion as of March 31, 2016 and $6.9 billion as of December 31, 2015 . (8) Represents the amount of our obligation that is not covered by pledged collateral and/or is not subject to an enforceable MRA or MSLA. REPURCHASE AND SECURITIES LENDING AGREEMENTS Securities sold under repurchase agreements and securities lending arrangements are effectively short-term collateralized borrowings. In these transactions, we receive cash in exchange for transferring securities as collateral and recognize an obligation to reacquire the securities for cash at the transaction's maturity. These types of transactions create risks, including (1) the counterparty may fail to return the securities at maturity, (2) the fair value of the securities transferred may decline below the amount of our obligation to reacquire the securities, and therefore create an obligation for us to pledge additional amounts, and (3) the counterparty may accelerate the maturity on demand requiring us to reacquire the security prior to contractual maturity. We attempt to mitigate these risks by the fact that the majority of our securities financing activities involve highly liquid securities, we underwrite and monitor the financial strength of our counterparties, we monitor the fair value of collateral pledged relative to contractually required repurchase amounts, and we monitor that our collateral is properly returned through the clearing and settlement process in advance of our cash repayment. Table 10.4 provides the underlying collateral types of our gross obligations under repurchase and securities lending agreements.

Commitments and Contingencies Disclosure [Abstract]
Legal Actions	Note 11: Legal Actions The following supplements our discussion of certain matters previously reported in Note 15 (Legal Actions) to Financial Statements in our 2015 Form 10-K for events occurring during first quarter 2016. 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 February 1, 2016, Wells Fargo reached an agreement in principle with the United States Department of Justice, the United States Attorney’s Office for the Southern District of New York, the United States Attorney’s Office for the Northern District of California, and HUD (collectively, the Federal Government) to pay $1.2 billion to resolve the complaint’s allegations, as well as other potential civil claims relating to Wells Fargo’s FHA lending activities for other periods. The parties arrived at a final settlement which was entered by the court on April 8, 2016. ORDER OF POSTING LITIGATION A series of putative class actions have been filed against Wachovia Bank, N.A. and Wells Fargo Bank, N.A., as well as many other banks, challenging the "high to low" order in which the banks post debit card transactions to consumer deposit accounts. There are currently several such cases pending against Wells Fargo Bank (including the Wachovia Bank cases to which Wells Fargo succeeded), most of which have been consolidated in multi- district litigation proceedings (the "MDL proceedings") in the U.S. District Court for the Southern District of Florida. The court in the MDL proceedings has certified a class of putative plaintiffs and Wells Fargo has moved to compel arbitration of the claims of unnamed class members. On August 10, 2010, the U.S. District Court for the Northern District of California issued an order in Gutierrez v. Wells Fargo Bank, N.A. , a case that was not consolidated in the MDL proceedings described above, enjoining the bank’s use of the high to low posting method for debit card transactions with respect to the plaintiff class of California depositors, directing the bank to establish a different posting methodology and ordering remediation of approximately $203 million . On October 26, 2010, a final judgment was entered in Gutierrez. Following appellate proceedings which reversed in part and affirmed in part the trial court's judgment, Wells Fargo filed a petition for writ of certiorari to the United States Supreme Court on April 10, 2015. The Supreme Court denied that petition on April 4, 2016. 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 approximately $1.1 billion as of March 31, 2016 . 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 certain derivatives as hedging instruments in a qualifying hedge accounting relationship (fair value or cash flow hedge). Our remaining derivatives consist of economic hedges that do not qualify for hedge accounting and derivatives held for customer accommodation, trading, or other purposes. For more information on our derivative activities, see Note 16 (Derivatives) to Financial Statements in our 2015 Form 10-K. Table 12.1 presents the total notional or contractual amounts and fair values for our derivatives. Derivative transactions can be measured in terms of the notional amount, but this amount is not recorded on 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 hedging instruments and economic hedges are recorded on the balance sheet at fair value in other assets or other liabilities. Customer accommodation, trading and other derivatives are recorded on the balance sheet at fair value in trading assets, other assets or other liabilities.

The notional amount for foreign exchange contracts at March 31, 2016 , and December 31, 2015 excludes $8.1 billion and $7.8 billion , respectively, for certain derivatives that are combined for designation as a hedge on a single instrument. (2) Includes economic hedge derivatives used to hedge the risk of changes in the fair value of residential MSRs, MHFS, loans, derivative loan commitments and other interests held. (3) Represents balance sheet netting of derivative asset and liability balances, related cash collateral and portfolio level counterparty valuation adjustments. See the next table in this Note for further information. Table 12.2 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 includes $104.9 billion and $106.1 billion of gross derivative assets and liabilities, respectively, at March 31, 2016 , and $69.9 billion and $74.0 billion , respectively, at December 31, 2015 , 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 $15.8 billion and $6.4 billion , respectively, at March 31, 2016 and $14.6 billion and $5.9 billion , respectively, at December 31, 2015 , 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 receive and pledge. For disclosure purposes, we present the fair value of this non-cash collateral 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 Table 12.2 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).

Counterparty valuation adjustments were $433 million and $375 million related to derivative assets and $89 million and $81 million related to derivative liabilities at March 31, 2016 and December 31, 2015 , respectively. Cash collateral totaled $7.8 billion and $4.8 billion , netted against derivative assets and liabilities, respectively, at March 31, 2016 , and $5.3 billion and $4.7 billion , respectively, at December 31, 2015 . (2) Net derivative assets of $10.5 billion and $12.4 billion are classified in Trading assets at March 31, 2016 and December 31, 2015 , respectively. $9.5 billion and $5.3 billion are classified in Other assets in the consolidated balance sheet at March 31, 2016 and December 31, 2015 , 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 that are 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 2015 Form 10-K. Table 12.3 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 2015 Form 10-K. Based upon current interest rates, we estimate that $912 million (pre tax) of deferred net gains on derivatives in OCI at March 31, 2016 , 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 . Table 12.4 shows the net gains (losses) recognized related to derivatives in cash flow hedging relationships. Table 12.4: Derivatives in Cash Flow Hedging Relationships Quarter ended March 31, (in millions) 2016 2015 Gains (losses) (pre tax) recognized in OCI on derivatives 1,999 952 Gains (pre tax) reclassified from cumulative OCI into net income (1) 256 234 Gains (losses) (pre tax) recognized in noninterest income for hedge ineffectiveness (2) 1 1 (1) See Note 17 (Other Comprehensive Income) for detail on components of net income. (2) None of the change in value of the derivatives was excluded from the assessment of hedge effectiveness. Derivatives Not Designated as Hedging Instruments We use economic hedges primarily 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 hedge derivatives 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 $1.5 billion in first quarter 2016 , and $881 million in first quarter 2015 , which are included in mortgage banking noninterest income. The aggregate fair value of these derivatives was a net asset of $340 million at March 31, 2016 , and net liability of $3 million at December 31, 2015 . 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 mortgage loans that we intend to sell are considered derivatives. The aggregate fair value of derivative loan commitments on the balance sheet was a net asset of $179 million and $56 million at March 31, 2016 , and December 31, 2015 , respectively, and is included in the caption “Interest rate contracts” under “Customer accommodation, trading and other derivatives” in Table 12.1 in this Note. For more information on economic hedges and other derivatives, see Note 16 (Derivatives) to Financial Statements in our 2015 Form 10-K. Table 12.5 shows the net gains recognized in the income statement related to derivatives not designated as hedging instruments.

(4) Reflected in mortgage banking noninterest income including gains (losses) on interest rate lock commitments. (5) Predominantly included in net gains from trading activities in noninterest income. Credit Derivatives Credit derivative contracts are arrangements whose value is derived from the transfer of credit risk of a reference asset or entity from one party (the purchaser of credit protection) to another party (the seller of credit protection). We 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.

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 $13.7 billion at March 31, 2016 , and $12.3 billion at December 31, 2015 , for which we posted $10.0 billion and $8.8 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 March 31, 2016 , or December 31, 2015 , we would have been required to post additional collateral of $3.7 billion or $3.6 billion , respectively, or potentially settle the contract in an amount equal to its fair value. Some contracts require that we provide more collateral than the fair value of derivatives that are in a net liability position if a downgrade occurs. 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 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 Table 13.2 in this Note. From time to time, we may be required to measure at fair value other assets on a nonrecurring basis, such as certain residential and commercial MHFS, certain LHFS, loans held for investment, nonmarketable equity investments and certain other assets. These nonrecurring fair value adjustments typically involve application of LOCOM accounting or write-downs of individual assets. See Note 1 (Summary of Significant Accounting Policies) to Financial Statements in our 2015 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 that are not recorded at fair value, see Note 17 (Fair Values of Assets and Liabilities) to Financial Statements in our 2015 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 that are 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. In accordance with new accounting guidance that we adopted effective January 1, 2016, we do not classify certain investments in the fair value hierarchy if we use the net asset value (NAV) per share (or its equivalent) as a practical expedient to measure fair value. This guidance was required to be applied retrospectively. Accordingly, certain prior period fair value disclosures have been revised to conform with current period presentation. Marketable equity investments with published NAVs continue to be classified in the fair value hierarchy. Fair Value Measurements from Vendors For certain assets and liabilities, we obtain fair value measurements from vendors, which predominantly consist of third party pricing services, and record the unadjusted fair value in our financial statements. For additional information, see Note 17 (Fair Values of Assets and Liabilities) to Financial Statements in our 2015 Form 10-K. Table 13.1 . presents unadjusted fair value measurements provided by brokers or third-party pricing services by fair value hierarchy level. 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 excluded from Table 13.1 .

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 are provided within Table 13.3 for the periods presented. The amounts reported as transfers represent the fair value as of the beginning of the quarter in which the transfer occurred.

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 2015 Form 10-K.

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.

Segment Reporting [Abstract]
Operating Segments	Note 18: Operating Segments We have three reportable operating segments: Community Banking; Wholesale Banking; and Wealth and Investment Management. We define our operating segments by product type and customer segment and their results 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. If the management structure and/or the allocation process changes, allocations, transfers and assignments may change. For a description of our operating segments, including the underlying management accounting process, see Note 24 (Operating Segments) to Financial Statements in our 2015 Form 10-K.

(2) Net interest income is the difference between interest earned on assets and the cost of liabilities to fund those assets. Interest earned includes actual interest earned on segment assets and, if the segment has excess liabilities, interest credits for providing funding to other segments. The cost of liabilities includes interest expense on segment liabilities and, if the segment does not have enough liabilities to fund its assets, a funding charge based on the cost of excess liabilities from another segment. (3) Represents segment net income (loss) for Community Banking; Wholesale Banking; and Wealth and Investment Management segments and Wells Fargo net income for the consolidated company.

Regulatory and Agency Capital R

Regulatory and Agency Capital Requirements	3 Months Ended
	Mar. 31, 2016
Banking and Thrift [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 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). Table 19.1 presents regulatory capital information for Wells Fargo & Company and the Bank using Basel III, which increased minimum required capital ratios, and introduced a minimum Common Equity Tier 1 (CET1) ratio. Beginning second quarter 2015, our capital ratios were calculated in accordance with the Standardized and Advanced Approaches. Accordingly, we must report the lower of our CET1, tier 1 and total capital ratios calculated under the Standardized Approach and under the Advanced Approach in the assessment of our capital adequacy. The information presented reflects risk-weighted assets (RWAs) under the Standardized and Advanced Approaches with Transition Requirements. The Standardized Approach applies assigned risk weights to broad risk categories, while the calculation of RWAs under the Advanced Approach differs by requiring applicable banks to utilize a risk-sensitive methodology, which relies upon the use of internal credit models, and includes an operational risk component. The Basel III revised definition of capital, and changes are being phased-in effective January 1, 2014, through the end of 2021. The Bank is an approved seller/servicer of mortgage loans 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 March 31, 2016 , 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.

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. We also hold a majority interest in a real estate investment trust, which has publicly traded preferred stock outstanding.
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, 2015 ( 2015 Form 10-K). There were no material changes to these policies in first quarter 2016 . To prepare the financial statements in conformity with GAAP, management must make estimates based on assumptions about future economic and market conditions (for example, unemployment, market liquidity, real estate prices, etc.) that affect the reported amounts of assets and liabilities at the date of the financial statements, income and expenses during the reporting period and the related disclosures. Although our estimates contemplate current conditions and how we expect them to change in the future, it is reasonably possible that actual conditions could be worse than anticipated in those estimates, which could materially affect our results of operations and financial condition. Management has made significant estimates in several areas, including allowance for credit losses 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)), 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 2015 Form 10-K.
Accounting Standards Adopted in 2015	Accounting Standards Adopted in 2016 In first quarter 2016 , we adopted the following new accounting guidance: • Accounting Standards Update (ASU or Update) 2015-16 – Business Combinations ( Topic 805 ): Simplifying the Accounting for Measurement-Period Adjustments; • ASU 2015-07 – Fair Value Measurement (Topic 820): Disclosures for Investments in Certain Entities that Calculate Net Asset Value per Share (or Its Equivalent); • ASU 2015-03 – Interest – Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs; • ASU 2015-02 – Consolidation (Topic 810): Amendments to the Consolidation Analysis; • ASU 2015-01 – Income Statement – Extraordinary and Unusual Items (Subtopic 225-20): Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items; • ASU 2014-16 – Derivatives and Hedging (Topic 815): Determining Whether the Host Contract in a Hybrid Financial Instrument Issued in the Form of a Share is More Akin to Debt or to Equity; • ASU 2014-13 – Consolidation (Topic 810): Measuring the Financial Assets and the Financial Liabilities of a Consolidated Collateralized Financing Entity; and • ASU 2014-12 – Compensation – Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period.
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 2015 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 2015 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. We had no unsettled private share repurchase contracts at March 31, 2016 . At March 31, 2015 , we had a $750 million private repurchase contract outstanding that settled in April 2015 for 14.0 million shares of common stock.
Subsequent Events	SUBSEQUENT EVENTS We have evaluated the effects of events that have occurred subsequent to March 31, 2016 , and there have been no material events that would require recognition in our first quarter 2016 consolidated financial statements or disclosure in the Notes to the consolidated financial statements.
Accounting Standards Update 2015-16 [Member]
Significant Accounting Policies [Line Items]
Accounting Standards Adopted in 2015	ASU 2015-16 eliminates the requirement for companies to retrospectively adjust initial amounts recognized in business combinations when the accounting is incomplete at the acquisition date. Under the new guidance, companies should record adjustments in the same reporting period in which the amounts are determined. We adopted this accounting change in first quarter 2016 with prospective application. The Update did not have a material impact on our consolidated financial statements.
Accounting Standards Update 2015-07 [Member]
Significant Accounting Policies [Line Items]
Accounting Standards Adopted in 2015	ASU 2015-07 eliminates the disclosure requirement to categorize investments within the fair value hierarchy that are measured at fair value using net asset value as a practical expedient. We adopted this change in first quarter 2016 with retrospective application. The Update did not affect our consolidated financial statements as it impacts only the fair value disclosure requirements for certain investments. For additional information, see Note 13 (Fair Values of Assets and Liabilities).
Accounting Standards Update 2015-03 [Member]
Significant Accounting Policies [Line Items]
Accounting Standards Adopted in 2015	ASU 2015-03 changes the balance sheet presentation for debt issuance costs. Under the new guidance, debt issuance costs should be reported as a deduction from debt liabilities rather than as a deferred charge classified as an asset. We adopted this change in first quarter 2016, which resulted in a $180 million reclassification from Other assets to Long-term debt on January 1, 2016. Because the impact on prior periods was not material, we applied the guidance prospectively.
Accounting Standards Update 2015-02 [Member]
Significant Accounting Policies [Line Items]
Accounting Standards Adopted in 2015	ASU 2015-02 requires companies to reevaluate all legal entities under new consolidation guidance. The new guidance primarily amends the criteria companies use to evaluate whether they should consolidate certain variable interest entities that have fee arrangements and the criteria used to determine whether partnerships and similar entities are variable interest entities. The new guidance also amends the consolidation analysis for certain investment funds and excludes certain money market funds. We adopted the accounting changes on January 1, 2016, which resulted in a net increase in assets and a corresponding cumulative-effect adjustment to noncontrolling interests of $121 million . There was no impact to consolidated retained earnings. For additional information, see Note 7 (Securitizations and Variable Interest Entities).
Accounting Standards Update 2015-01 [Member]
Significant Accounting Policies [Line Items]
Accounting Standards Adopted in 2015	ASU 2015-01 removes the concept of extraordinary items from GAAP and eliminates the requirement for extraordinary items to be separately presented in the statement of income. We adopted this change in first quarter 2016 with prospective application. This Update did not have a material impact on our consolidated financial statements.
Accounting Standards Update 2014-16 [Member]
Significant Accounting Policies [Line Items]
Accounting Standards Adopted in 2015	ASU 2014-16 clarifies that the nature of host contracts in hybrid financial instruments that are issued in share form should be determined based on the entire instrument, including the embedded derivative. We adopted this new requirement in first quarter 2016. This Update did not have a material impact on our consolidated financial statements.
Accounting Standards Update 2014-13 [Member]
Significant Accounting Policies [Line Items]
Accounting Standards Adopted in 2015	ASU 2014-13 provides a measurement alternative to companies that consolidate collateralized financing entities (CFEs), such as collateralized debt obligation and collateralized loan obligation structures. Under the new guidance, companies can measure both the financial assets and financial liabilities of a CFE using the more observable fair value of the financial assets or of the financial liabilities. We adopted this accounting change in first quarter 2016. The Update did not have a material impact on our consolidated financial statements.
Accounting Standards Update 2014-12 [Member]
Significant Accounting Policies [Line Items]
Accounting Standards Adopted in 2015	ASU 2014-12 provides accounting guidance for employee share-based payment awards with specific performance targets. The Update clarifies that performance targets should be treated as performance conditions if the targets affect vesting and could be achieved after the requisite service period. We adopted this change in first quarter 2016 with prospective application. The Update did not have a material effect on our consolidated financial statements, as our historical practice complies with the new requirements.

Investment Securities Gross Unrealized Losses Over And Under 12 Months	Table 4.2 shows the gross unrealized losses and fair value of securities in the investment securities portfolio by length of time that individual securities in each category have been in a continuous loss position. Debt securities on which we have taken credit-related OTTI write-downs are categorized as being “less than 12 months” or “12 months or more” in a continuous loss position based on the point in time that the fair value declined to below the cost basis and not the period of time since the credit-related OTTI write-down.

Investment Securities Gross Unrealized Losses By Investment Grade	Table 4.3 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 our 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 $24 million and $4.8 billion , respectively, at March 31, 2016 , and $17 million and $3.7 billion , respectively, at December 31, 2015 . If an internal credit grade was not assigned, we categorized the security as non-investment grade.

Debt Securities Contractual Maturities	Table 4.4 shows the remaining contractual maturities and contractual weighted-average yields (taxable-equivalent basis) of available-for-sale debt securities. The remaining contractual principal maturities for MBS do not consider prepayments. Remaining expected maturities will differ from contractual maturities because borrowers may have the right to prepay obligations before the underlying mortgages mature.

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.
Credit Loss Component Of Credit-Impaired Debt Securities	Table 4.10 presents a rollforward of the OTTI credit loss that has been recognized in earnings as a write-down of available-for-sale debt securities we still own (referred to as "credit-impaired" debt securities) and do not intend to sell. Recognized credit loss 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 loss. Table 4.10: Rollforward of OTTI Credit Loss Quarter ended March 31, (in millions) 2016 2015 Credit loss recognized, beginning of period $ 1,092 1,025 Additions: For securities with initial credit impairments 38 — For securities with previous credit impairments 23 20 Total additions 61 20 Reductions: For securities sold, matured, or intended/required to be sold (6 ) (14 ) For recoveries of previous credit impairments (1) (2 ) (2 ) Total reductions (8 ) (16 ) Credit loss recognized, end of period $ 1,145 1,029 (1) 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.

Loans and Allowance for Credit Losses, Significant Activity	Table 5.3 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 for which we have elected the fair value option, including loans originated for sale because their loan activity normally does not impact the allowance for credit losses.

As servicer, we are able to buy delinquent insured/guaranteed loans out of the Government National Mortgage Association (GNMA) pools, and manage and/or resell them in accordance with applicable requirements. These loans are predominantly insured by the Federal Housing Administration (FHA) or guaranteed by the Department of Veterans Affairs (VA). Accordingly, these loans have limited impact on the allowance for loan losses.

Loans by Loan to Value Ratio, Consumer	Table 5.12 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. Table 5.12: Consumer Loans by LTV/CLTV March 31, 2016 December 31, 2015 (in millions) Real estate 1-4 family first mortgage by LTV Real estate 1-4 family junior lien mortgage by CLTV Total Real estate 1-4 family first mortgage by LTV Real estate 1-4 family junior lien mortgage by CLTV Total By LTV/CLTV: 0-60% $ 109,138 15,390 124,528 109,558 15,805 125,363 60.01-80% 93,772 16,155 109,927 92,005 16,579 108,584 80.01-100% 24,089 10,979 35,068 22,765 11,385 34,150 100.01-120% (1) 4,225 5,331 9,556 4,480 5,545 10,025 > 120% (1) 1,950 2,871 4,821 2,065 3,051 5,116 No LTV/CLTV available 1,453 538 1,991 1,453 570 2,023 Government insured/guaranteed loans (2) 21,573 — 21,573 22,353 — 22,353 Total consumer loans (excluding PCI) 256,200 51,264 307,464 254,679 52,935 307,614 Total consumer PCI loans (carrying value) 18,534 60 18,594 19,190 69 19,259 Total consumer loans $ 274,734 51,324 326,058 273,869 53,004 326,873 (1) Reflects total loan balances with LTV/CLTV amounts in excess of 100%.

Nonaccrual Loans	Table 5.13 provides loans on nonaccrual status.

Impaired Loans	Table 5.15 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.

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 $348 million and $522 million , for quarters ended March 31, 2016 and 2015 , 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 $19 million and $26 million for the quarters ended March 31, 2016 and 2015 , respectively. (5) Reflects the effect of reduced interest rates on loans with an interest rate concession as one of their concession types, which includes loans reported as a principal primary modification type that also have an interest rate concession. (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.
Troubled Debt Restructuring, Current Defaults	Table 5.18 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.

Unconsolidated VIEs	Table 7.2 provides 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 (unless we are servicer and have other significant forms of involvement) or if we were the sponsor only or sponsor and servicer but do not have any other forms of significant 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 (other than those held temporarily in 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 of the unconsolidated VIEs. We also exclude from the table secured borrowing transactions with unconsolidated VIEs (for information on these transactions, see the Transactions with Consolidated VIEs and Secured Borrowings section in this Note).

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. (2) Excludes assets and related liabilities with a recorded carrying value on our balance sheet of $938 million and $1.3 billion at March 31, 2016 , and December 31, 2015 , 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. (3) 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 70% were rated as investment grade by the primary rating agencies at March 31, 2016 , and December 31, 2015 , respectively. These senior loans are accounted for at amortized cost and are subject to the Company’s allowance and credit charge-off policies. (4) Includes structured financing 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.
Cash Flows from Sales and Securitization Activity	Table 7.3 presents the cash flows for our transfers accounted for as sales. Table 7.3: Cash Flows From Sales and Securitization Activity 2016 2015 (in millions) Mortgage loans Other financial assets Mortgage loans Other financial assets Quarter ended March 31, Proceeds from securitizations and whole loan sales $ 45,016 50 41,909 21 Fees from servicing rights retained 881 — 935 2 Cash flows from other interests held (1) 407 1 266 12 Repurchases of assets/loss reimbursements (2): Non-agency securitizations and whole loan transactions 3 — 6 — Agency securitizations (3) 47 — 62 — Servicing advances, net of repayments (68 ) — (100 ) — (1) Cash flows from other interests held include principal and interest payments received on retained bonds and excess cash flows received on interest-only strips. (2) Consists of cash paid to repurchase loans from investors and cash paid to investors to reimburse them for losses on individual loans that are already liquidated. (3) Represent loans repurchased from GNMA, FNMA, and FHLMC under representation and warranty provisions included in our loan sales contracts. First quarter 2016 and 2015 exclude $ 2.9 billion and $ 3.3 billion , respectively, in delinquent insured/guaranteed loans that we service and have exercised our option to purchase out of GNMA pools. These loans are predominantly insured by the FHA or guaranteed by the VA.
Residential Mortgage Servicing Rights	Table 7.4 presents the key weighted-average assumptions we used to measure residential mortgage servicing rights at the date of securitization. Table 7.4: Residential Mortgage Servicing Rights Residential mortgage servicing rights 2016 2015 Quarter ended March 31, Prepayment speed (1) 13.0 % 13.0 Discount rate 6.8 7.5 Cost to service ($ per loan) (2) $ 146 237 (1) 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. (2) Includes costs to service and unreimbursed foreclosure costs, which can vary period to period depending on the mix of modified government-guaranteed loans sold to GNMA.
Retained Interests from Unconsolidated VIEs	Table 7.5 provides key economic assumptions and the sensitivity of the current fair value of residential mortgage servicing rights and other interests held 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. Table 7.5: Retained Interests from Unconsolidated VIEs Other interests held Residential mortgage servicing rights (1) Interest-only strips Consumer Commercial (2) ($ in millions, except cost to service amounts) Subordinated bonds Subordinated bonds Senior bonds Fair value of interests held at March 31, 2016 $ 11,333 32 1 337 778 Expected weighted-average life (in years) 5.6 3.5 10.2 1.5 6.0 Key economic assumptions: Prepayment speed assumption (3) 12.6 % 19.5 16.5 Decrease in fair value from: 10% adverse change $ 604 1 — 25% adverse change 1,429 3 — Discount rate assumption 6.9 % 13.6 10.0 6.5 2.7 Decrease in fair value from: 100 basis point increase $ 539 1 — 5 39 200 basis point increase 1,029 1 — 9 76 Cost to service assumption ($ per loan) 164 Decrease in fair value from: 10% adverse change 537 25% adverse change 1,343 Credit loss assumption 2.0 % 2.6 — Decrease in fair value from: 10% higher losses $ — — — 25% higher losses — 3 — Fair value of interests held at December 31, 2015 $ 12,415 34 1 342 673 Expected weighted-average life (in years) 6.0 3.6 11.6 1.9 5.8 Key economic assumptions: Prepayment speed assumption (3) 11.4 % 19.0 15.1 Decrease in fair value from: 10% adverse change $ 616 1 — 25% adverse change 1,463 3 — Discount rate assumption 7.3 % 13.8 10.5 5.3 3.0 Decrease in fair value from: 100 basis point increase $ 605 1 — 6 33 200 basis point increase 1,154 1 — 11 63 Cost to service assumption ($ per loan) 168 Decrease in fair value from: 10% adverse change 567 25% adverse change 1,417 Credit loss assumption 1.1 % 2.8 — Decrease in fair value from: 10% higher losses $ — — — 25% higher losses — 2 — (1) See narrative following this table for a discussion of commercial mortgage servicing rights. (2) 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. (3) 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.
Off-Balance Sheet Loans Sold Or Securitized	Table 7.6 presents information about the principal balances of off-balance sheet loans that were sold or securitized, including residential mortgage loans sold to FNMA, FHLMC, GNMA and other investors, for which we have some form of continuing involvement (primarily servicer). Delinquent loans include loans 90 days or more past due and loans in bankruptcy, regardless of delinquency status. For loans sold or securitized where servicing is our only form of continuing involvement, we would only experience a loss if we were required to repurchase a delinquent loan or foreclosed asset due to a breach in representations and warranties associated with our loan sale or servicing contracts. Table 7.6: Off-Balance Sheet Loans Sold or Securitized Net charge-offs Total loans Delinquent loans and foreclosed assets (1) Quarter ended Mar 31, (in millions) Mar 31, 2016 Dec 31, 2015 Mar 31, 2016 Dec 31, 2015 2016 2015 Commercial: Real estate mortgage $ 113,069 110,815 2,730 6,670 83 52 Total commercial 113,069 110,815 2,730 6,670 83 52 Consumer: Real estate 1-4 family first mortgage 1,216,440 1,235,662 19,725 20,904 287 205 Total consumer 1,216,440 1,235,662 19,725 20,904 287 205 Total off-balance sheet sold or securitized loans (2) $ 1,329,509 1,346,477 22,455 27,574 370 257 (1) Includes $1.9 billion and $5.0 billion of commercial foreclosed assets and $2.1 billion and $2.2 billion of consumer foreclosed assets at March 31, 2016 , and December 31, 2015 , respectively. (2) At March 31, 2016 , and December 31, 2015 , the table includes total loans of $1.2 trillion at both dates, delinquent loans of $10.9 billion and $12.1 billion , and foreclosed assets of $1.6 billion and $1.7 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	Table 7.7 presents a summary of financial assets and liabilities for asset transfers accounted for as secured borrowings and involvements with consolidated VIEs. “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.

See Note 12 (Derivatives Not Designated as Hedging Instruments) for additional discussion and detail.
Analysis of Changes in Liability for Mortgage Loan Repurchase Losses	Table 8.5 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 exceeded our recorded liability by $274 million at March 31, 2016 , and was determined based upon modifying the assumptions (particularly to assume significant changes in investor repurchase demand practices) used in our best estimate of probable loss to reflect what we believe to be the high end of reasonably possible adverse assumptions. Table 8.5: Analysis of Changes in Liability for Mortgage Loan Repurchase Losses Quarter ended March 31, (in millions) 2016 2015 Balance, beginning of period $ 378 615 Provision for repurchase losses: Loan sales 7 10 Change in estimate (1) (19 ) (26 ) Net reductions (12 ) (16 ) Losses (11 ) (13 ) Balance, end of period $ 355 586 (1) Results from changes in investor demand and mortgage insurer practices, credit deterioration and changes in the financial stability of correspondent lenders.

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. (2) Includes indemnifications provided to certain third-party clearing agents. Outstanding customer obligations under these arrangements were $208 million and $352 million with related collateral of $952 million and $1.5 billion at March 31, 2016 , and December 31, 2015 , respectively. Estimated maximum exposure to loss was $1.2 billion and $1.8 billion as of the same periods, respectively. (3) Written put options, which are in the form of derivatives, are also included in the derivative disclosures in Note 12 (Derivatives). (4) Represent recourse provided, predominantly to the GSEs, on loans sold under various programs and arrangements. Under these arrangements, we repurchased $1 million of loans associated with these agreements in both first quarter 2016 and 2015 . (5) 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.
Significant Components of Assets Pledged	Table 10.2 provides the total carrying amount of pledged assets by asset type. The table excludes pledged consolidated VIE assets of $15.2 billion and $5.6 billion at March 31, 2016 , and December 31, 2015 , respectively, which can only be used to settle the liabilities of those entities. The table also excludes $6.3 billion and $7.3 billion in assets pledged in transactions accounted for as secured borrowings at March 31, 2016 , and December 31, 2015 , respectively. See Note 7 (Securitizations and Variable Interest Entities) for additional information on consolidated VIE assets and secured borrowings.

Balance includes $87.0 billion and $73.0 billion at March 31, 2016 , and December 31, 2015 , respectively, under agreements that permit the secured parties to sell or repledge the collateral. (2) Includes carrying value of $5.5 billion and $6.5 billion (fair value of $5.5 billion and $ 6.5 billion ) in collateral for repurchase agreements at March 31, 2016 , and December 31, 2015 , respectively, which are pledged under agreements that do not permit the secured parties to sell or repledge the collateral. Also includes $12.9 billion and $13.0 billion in collateral pledged under repurchase agreements at March 31, 2016 , and December 31, 2015 , respectively, that permit the secured parties to sell or repledge the collateral. Substantially all other pledged securities are pursuant to agreements that do not permit the secured party to sell or repledge the collateral. (3) Includes mortgages held for sale of $9.9 billion and $8.7 billion at March 31, 2016 , and December 31, 2015 , respectively. Balance consists of mortgages held for sale and loans that are pledged under agreements that do not permit the secured parties to sell or repledge the collateral. Amounts exclude $938 million and $1.3 billion at March 31, 2016 , and December 31, 2015 , 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	Table 10.3 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 liability. Collateral we received includes securities or loans and is not recognized on our balance sheet. Collateral pledged or received may be increased or decreased over time to maintain certain contractual thresholds as the assets underlying each arrangement fluctuate in value. Generally, these agreements require collateral to exceed the asset or liability recognized on the balance sheet. The following table includes the amount of collateral pledged or received related to exposures subject to enforceable MRAs or MSLAs. While these agreements are typically over-collateralized, U.S. GAAP requires disclosure in this table to limit the amount of such collateral to the amount of the related recognized asset or liability for each counterparty. In addition to the amounts included in Table 10.3 , we also have balance sheet netting related to derivatives that is disclosed in Note 12 (Derivatives). Table 10.3: Offsetting – Resale and Repurchase Agreements (in millions) Mar 31, Dec 31, Assets: Resale and securities borrowing agreements Gross amounts recognized $ 82,400 74,935 Gross amounts offset in consolidated balance sheet (1) (11,653 ) (9,158 ) Net amounts in consolidated balance sheet (2) 70,747 65,777 Collateral not recognized in consolidated balance sheet (3) (69,933 ) (65,035 ) Net amount (4) $ 814 742 Liabilities: Repurchase and securities lending agreements Gross amounts recognized (5) $ 104,066 91,278 Gross amounts offset in consolidated balance sheet (1) (11,653 ) (9,158 ) Net amounts in consolidated balance sheet (6) 92,413 82,120 Collateral pledged but not netted in consolidated balance sheet (7) (92,044 ) (81,772 ) Net amount (8) $ 369 348 (1) Represents recognized amount of resale and repurchase agreements with counterparties subject to enforceable MRAs or MSLAs that have been offset in the consolidated balance sheet.

At March 31, 2016 , and December 31, 2015 , we have received total collateral with a fair value of $93.3 billion and $84.9 billion , respectively, all of which, we have the right to sell or repledge. These amounts include securities we have sold or repledged to others with a fair value of $57.8 billion at March 31, 2016 , and $51.1 billion at December 31, 2015 . (4) Represents the amount of our exposure that is not collateralized and/or is not subject to an enforceable MRA or MSLA. (5) For additional information on underlying collateral and contractual maturities, see the "Repurchase and Securities Lending Agreements" section in this Note. (6) Amount is classified in short-term borrowings on our consolidated balance sheet. (7) Represents the fair value of collateral we have pledged, related to enforceable MRAs or MSLAs, limited for table presentation purposes to the amount of the recognized liability owed to each counterparty. At March 31, 2016 , and December 31, 2015 , we have pledged total collateral with a fair value of $105.9 billion and $92.9 billion , respectively, of which, the counterparty does not have the right to sell or repledge $6.0 billion as of March 31, 2016 and $6.9 billion as of December 31, 2015 .

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Notional or Contractual Amounts and Fair Values of Derivatives	Table 12.1 presents the total notional or contractual amounts and fair values for our derivatives. Derivative transactions can be measured in terms of the notional amount, but this amount is not recorded on 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 hedging instruments and economic hedges are recorded on the balance sheet at fair value in other assets or other liabilities. Customer accommodation, trading and other derivatives are recorded on the balance sheet at fair value in trading assets, other assets or other liabilities.

The notional amount for foreign exchange contracts at March 31, 2016 , and December 31, 2015 excludes $8.1 billion and $7.8 billion , respectively, for certain derivatives that are combined for designation as a hedge on a single instrument. (2) Includes economic hedge derivatives used to hedge the risk of changes in the fair value of residential MSRs, MHFS, loans, derivative loan commitments and other interests held. (3) Represents balance sheet netting of derivative asset and liability balances, related cash collateral and portfolio level counterparty valuation adjustments. See the next table in this Note for further information.
Gross Fair Value of Derivative Assets and Liabilities	Table 12.2 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 includes $104.9 billion and $106.1 billion of gross derivative assets and liabilities, respectively, at March 31, 2016 , and $69.9 billion and $74.0 billion , respectively, at December 31, 2015 , 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 $15.8 billion and $6.4 billion , respectively, at March 31, 2016 and $14.6 billion and $5.9 billion , respectively, at December 31, 2015 , 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 receive and pledge. For disclosure purposes, we present the fair value of this non-cash collateral 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 Table 12.2 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).

Counterparty valuation adjustments were $433 million and $375 million related to derivative assets and $89 million and $81 million related to derivative liabilities at March 31, 2016 and December 31, 2015 , respectively. Cash collateral totaled $7.8 billion and $4.8 billion , netted against derivative assets and liabilities, respectively, at March 31, 2016 , and $5.3 billion and $4.7 billion , respectively, at December 31, 2015 . (2) Net derivative assets of $10.5 billion and $12.4 billion are classified in Trading assets at March 31, 2016 and December 31, 2015 , respectively. $9.5 billion and $5.3 billion are classified in Other assets in the consolidated balance sheet at March 31, 2016 and December 31, 2015 , 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 that are 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.
Derivatives in Fair Value Hedging Relationships	Table 12.3 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.

Fair Value, Assets and Liabilities Measured on Recurring Basis, Quantative Information about Valuation Techniques and Unobservable Inputs	Table 13.8 and Table 13.9 provide 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 2015 Form 10-K.

Fair Value, Assets and Liabilities Measured on Nonrecurring Basis, Quantative Information about Valuation Techniques and Unobservable Inputs	Table 13.12 provides quantitative information about the valuation techniques and significant unobservable inputs used in the valuation of most of our Level 3 assets and liabilities that are measured at fair value on a nonrecurring basis using an internal model. The table is limited to financial instruments that had nonrecurring fair value adjustments during the periods presented. 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 that 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.

Banking and Thrift [Abstract]
Regulatory And Agency Capital Requirements	Table 19.1 presents regulatory capital information for Wells Fargo & Company and the Bank using Basel III, which increased minimum required capital ratios, and introduced a minimum Common Equity Tier 1 (CET1) ratio. Beginning second quarter 2015, our capital ratios were calculated in accordance with the Standardized and Advanced Approaches. Accordingly, we must report the lower of our CET1, tier 1 and total capital ratios calculated under the Standardized Approach and under the Advanced Approach in the assessment of our capital adequacy. The information presented reflects risk-weighted assets (RWAs) under the Standardized and Advanced Approaches with Transition Requirements. The Standardized Approach applies assigned risk weights to broad risk categories, while the calculation of RWAs under the Advanced Approach differs by requiring applicable banks to utilize a risk-sensitive methodology, which relies upon the use of internal credit models, and includes an operational risk component. The Basel III revised definition of capital, and changes are being phased-in effective January 1, 2014, through the end of 2021. The Bank is an approved seller/servicer of mortgage loans 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 March 31, 2016 , 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.
