Accounting Policies [Abstract]
Accounting Policies	B USINESS PNC is one of the largest diversified financial services companies in the U.S. and is headquartered in Pittsburgh, Pennsylvania. CCOUNTING P OLICIES Basis of Financial Statement Presentation Our consolidated financial statements include the accounts of the parent company and its subsidiaries, most of which are wholly-owned, certain partnership interests and VIEs. On June 1, 2021, we acquired BBVA, a U.S. financial holding company conducting its business operations primarily through its U.S. banking subsidiary, BBVA USA. Our results for the first nine months of 2021 reflect BBVA's acquired business operations for the period since the acquisition closed on June 1, 2021. Our balance sheet at September 30, 2021 includes BBVA's balances. See Note 2 Acquisition and Divestiture Activity for additional information on this acquisition. We prepared these consolidated financial statements in accordance with GAAP. We have eliminated intercompany accounts and transactions. We have also reclassified certain prior year amounts to conform to the current period presentation, which did not have a material impact on our consolidated financial condition or results of operations. In our opinion, the unaudited interim consolidated financial statements reflect all normal, recurring adjustments needed to present fairly our results for the interim periods. The results of operations for interim periods are not necessarily indicative of the results that may be expected for the full year or any other interim period. We have also considered the impact of subsequent events on these consolidated financial statements. When preparing these unaudited interim consolidated financial statements, we have assumed that you have read the audited consolidated financial statements included in our 2020 Form 10-K. Reference is made to Note 1 Accounting Policies in our 2020 Form 10-K for a detailed description of significant accounting policies. These interim consolidated financial statements serve to update our 2020 Form 10-K and may not include all information and Notes necessary to constitute a complete set of financial statements. There have been no significant changes to our accounting policies as disclosed in our 2020 Form 10-K. Use of Estimates We prepared these consolidated financial statements using financial information available at the time of preparation, which requires us to make estimates and assumptions that affect the amounts reported. Our most significant estimates pertain to the ACL and our fair value measurements, including for the BBVA acquisition. Actual results may differ from the estimates and the differences may be material to the consolidated financial statements. Recently Adopted Accounting Standards Accounting Standards Update Description Financial Statement Impact Income Tax Simplification - ASU 2019-12 Issued December 2019 • Simplifies the accounting for income taxes by eliminating certain exceptions in ASC 740, Income Taxes , relating to the approach for intraperiod tax allocation, the recognition of deferred tax liabilities for outside basis differences and the methodology for calculating income taxes in an interim period. • Clarifies areas of the income tax guidance around franchise taxes partially based on income, step-ups in the tax basis of goodwill, and enacted changes in tax laws. • Specifies that an entity is no longer required to allocate the consolidated amount of current and deferred tax expense to a legal entity that is not subject to tax in its separate financial statements. • Adopted January 1, 2021. • The adoption of this standard did not impact our consolidated results of operations or our consolidated financial position. PNC will no longer allocate the consolidated amount of current and deferred income tax expense to certain qualifying stand-alone entities, which will impact the presentation of parent company tax expense subsequent to adoption. Accounting Standards Update Description Financial Statement Impact Reference Rate Reform - ASU 2020-04 Issued March 2020 Reference Rate Reform Scope - ASU 2021-01 Issued January 2021 • Provides optional expedients and exceptions for applying generally accepted accounting principles to contracts, hedging relationships and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform (codified in ASC 848). • Includes optional expedients related to contract modifications that allow an entity to account for modifications (if certain criteria are met) as if the modifications were only minor (assets within the scope of ASC 310, Receivables ), were not substantial (assets within the scope of ASC 470, Debt ) and/or did not result in remeasurements or reclassifications (assets within the scope of ASC 842, Leases , and other Topics) of the existing contract. • Includes optional expedients related to hedging relationships within the scope of ASC 815, Derivatives & Hedging , whereby changes to the critical terms of a hedging relationship do not require dedesignation if certain criteria are met. In addition, potential sources of ineffectiveness as a result of reference rate reform may be disregarded when performing some effectiveness assessments. • Includes optional expedients and exceptions for contract modifications and hedge accounting that apply to derivative instruments impacted by the market-wide discounting transition. • Allows for a one-time election to sell, transfer, or both sell and transfer debt securities classified as held to maturity that reference a rate affected by reference rate reform and that are classified as held to maturity before January 1, 2020. • Guidance in these ASUs are effective as of March 12, 2020 through December 31, 2022. • ASU 2020-04 was adopted March 12, 2020. ASU 2021-01 was retrospectively adopted October 1, 2020. • Refer to Note 1 Accounting Policies in the 2020 Form 10-K for more information on elections of optional expedients that occurred in 2020. • During the first quarter of 2021, we elected to apply certain optional expedients to derivative instruments that were modified in the first quarter due to the adoption of fallback language recommended by the ISDA to address the anticipated cessation of LIBOR. These optional expedients remove the requirement to remeasure contract modifications or dedesignate hedging relationships due to reference rate reform. • As of September 30, 2021, we have not yet elected to apply any optional expedients for contract modifications and hedging relationships to any other financial instruments. However, we plan to elect these optional expedients in the future. Accounting Standards Update Description Financial Statement Impact SEC Paragraph Amendments – ASU 2020-09 Issued October 2020 • Amends the financial disclosure requirements for guarantors and issuers of guaranteed securities registered or being registered, and issuers’ affiliates whose securities collateralize securities registered or being registered in Regulation S-X. • Improves disclosure requirements for both investors and registrants. • Provides investors with material information given the specific facts and circumstances, making the disclosures easier to understand and reducing the costs and burdens to registrants. • Adopted January 4, 2021. • In accordance with the requirements of this ASU, we included Exhibit 22 in the Exhibit Index of Item 6 of this Report to disclose PNC’s guarantee of the PNC Capital Trust C preferred securities.

Business Combinations [Abstract]
Acquisition and Divestiture Activity	A CQUISITION A ND D IVESTITURE A CTIVITY Acquisition of BBVA USA Bancshares, Inc. On June 1, 2021, PNC acquired BBVA including its U.S. banking subsidiary, BBVA USA, for $11.5 billion in cash. PNC did not acquire the following entities as part of the acquisition: BBVA Securities, Inc., Propel Venture Partners Fund I, L.P. and BBVA Processing Services, Inc. This transaction has been accounted for as a business combination. Accordingly, the assets and liabilities from BBVA were recorded at fair value as of the acquisition date. The determination of fair value requires management to make estimates about discount rates, future expected cash flows, market conditions and other future events that are highly subjective in nature and subject to change. Fair value estimates related to the assets and liabilities from BBVA are subject to adjustment for up to one year after the closing date of the acquisition as additional information becomes available. Valuations subject to adjustment include, but are not limited to, loans, certain deposits, certain other assets, customer relationships and the core deposit intangibles. As of October 12, 2021, PNC has converted approximately 2.6 million customers, 9,000 employees and over 600 branches across seven states, merging BBVA USA into PNC Bank. PNC incurred merger and integration costs of $243 million and $360 million for the three and nine months ended September 30, 2021, in connection with the transaction. These costs are recorded as contra-revenue and expense on the Consolidated Income Statement. The integration expenses are primarily related to personnel, technology, advisory and legal, with $49 million direct acquisition-related costs. Cumulative costs through September 30, 2021 were $367 million. The following table includes the preliminary fair value of the identifiable tangible and intangible assets and liabilities from BBVA: Table 34: Acquisition Consideration June 1, 2021 In millions Fair Value Fair value of acquisition consideration $ 11,480 Assets Cash and due from banks $ 969 Interest-earning deposits with banks 13,313 Loans held for sale 463 Investment securities – available for sale 18,358 Net loans 61,439 Equity investments 723 Mortgage servicing rights 35 Core deposit intangibles and other intangible assets 399 Other 3,531 Total assets $ 99,230 Liabilities Deposits $ 85,562 Borrowed funds 2,449 Accrued expenses and other liabilities 1,285 Total liabilities $ 89,296 Noncontrolling interests 22 Less: Net assets $ 9,912 Goodwill $ 1,568 Preliminary goodwill of $1.6 billion recorded in connection with the transaction resulted from the reputation, operating model and expertise of BBVA. The amount of goodwill recorded reflects the increased market share and related synergies that are expected to result from the acquisition, and represents the excess purchase price over the estimated fair value of the net assets from BBVA. The goodwill was allocated to each of our three business segments on a preliminary basis and is not deductible for income tax purposes. See Note 6 Goodwill and Mortgage Servicing Rights for additional information on the allocation of goodwill to the segments. Table 35: Fair Value and Unpaid Principal Balance of Loans from the BBVA Acquisition June 1, 2021 In millions Unpaid Principal Balance Fair Value Loans Commercial Commercial and industrial $ 29,864 $ 29,381 Commercial real estate 10,632 10,313 Equipment lease financing 48 48 Total commercial 40,544 39,742 Consumer Residential real estate 12,871 12,977 Home equity 2,430 2,423 Automobile 3,916 3,910 Credit card 820 758 Other consumer 1,688 1,629 Total consumer 21,725 21,697 Total $ 62,269 $ 61,439 Other intangible assets from the BBVA acquisition as of June 1, 2021 consisted of the following: Table 36: Intangible Assets In millions Fair Value Weighted Life Amortization Method Residential mortgage servicing rights $ 35 5.5 (a) Core deposits $ 283 10.0 Accelerated Other 116 9.8 Straight-line Total core deposits and other $ 399 (a) Intangible asset accounted for at fair value. The following is a description of the methods used to determine the fair values of significant assets and liabilities. Cash and Due from Banks and Interest-earning Deposits with Banks The carrying amount of these assets is a reasonable estimate of fair value based on the short-term nature of these assets. Loans Held for Sale Residential mortgage loans are valued based on quoted market prices, where available, prices for other traded mortgage loans with similar characteristics, and purchase commitments and bid information received from market participants. The prices are adjusted as necessary to include the embedded servicing value in the loans and to take into consideration the specific characteristics of certain similar loans. Personal installment loans are pooled based on delinquency status, and fair value of individual loans is calculated based on traded consumer unsecured loans, dealer research and loan level performance characteristics. Available For Sale Securities All investment securities from the BBVA acquisition were classified within the available for sale portfolio at acquisition. Fair value estimates for available for sale securities were determined by third-party pricing vendors. The third-party vendors use a variety of methods when pricing securities that incorporate relevant market data to arrive at an estimate of what a buyer in the marketplace would pay for a security under current market conditions. These methods include the use of quoted prices for the identical or a similar security, an alternative market-based approach or an income approach, such as a discounted cash flow pricing model. Loans Fair value for loans is based on a discounted cash flow methodology that considered credit loss and prepayment expectations, market interest rates and other market factors, such as liquidity, from the perspective of a market participant. Loan cash flows were generated on an individual loan basis. The PD, LGD, exposure at default and prepayment assumptions are the key factors driving credit losses which are embedded into the estimated cash flows. Equity Investments Equity investments primarily include LIHTC investments and preservation fund investments. The fair value of the LIHTC investments was estimated based on LIHTC pricing observed for recent transactions in markets where the properties underlying the LIHTC investments from the BBVA acquisition are located. The fair value of the preservation investments was estimated based on appraisals and valuations of the properties in the investment portfolio using income and market projections. Mortgage Servicing Rights The fair value of mortgage servicing rights from the BBVA acquisition is estimated by using a discounted cash flow valuation model which calculates the present value of estimated future net servicing cash flows, taking into consideration actual and expected mortgage loan prepayment rates, discount rates, servicing costs and other factors which are determined based on current market conditions. Core Deposit Intangible This intangible asset represents the value of certain client deposit relationships. The fair value was estimated utilizing the cost method. Appropriate consideration was given to deposit costs including servicing costs, client retention and alternative funding source costs at the time of acquisition. The discount rate used was derived taking into account the estimated cost of equity, risk-free return rate and risk premium for the market and specific risk related to the asset’s cash flows. The core deposit intangible is being amortized over 10 years using an accelerated depreciation methodology. Deposits The fair values for time deposits were estimated by discounting contractual cash flows using current market rates for instruments with similar maturities. For deposits with no defined maturity, carrying values approximate fair values. Borrowed Funds The fair values of long-term debt instruments were estimated based on quoted market prices. The following table presents financial results of BBVA included in the Consolidated Income Statement from the date of acquisition through September 30, 2021. Table 37: BBVA Financial Results In millions Four months ended September 30, 2021 Net interest income $ 768 Noninterest income $ 285 Net income $ 378 The following table presents unaudited pro forma results as if the acquisition of BBVA by PNC had occurred on January 1, 2020 and includes the impact of amortizing and accreting certain estimated purchase accounting adjustments such as intangible assets as well as fair value adjustments to loans, deposits and long-term debt. Merger and integration costs of $360 million that have been incurred since January 1, 2021 are included in the pro forma results. PNC's financial results include the divestiture of BlackRock of $4.3 billion recorded in net income. Additionally, BBVA's financial results through the nine months ended September 30, 2020 included a $2.2 billion goodwill impairment charge recorded in noninterest expense. The pro forma information does not necessarily reflect the results that would have occurred had PNC acquired BBVA on January 1, 2020.

PNC considers a variety of factors in connection with the identification of more-than-insignificant deterioration in credit quality, including but not limited to nonperforming status, delinquency, risk ratings, TDR classification, FICO scores and other qualitative factors that indicate deterioration in credit quality since origination. PNC initially measures the amortized cost of a PCD loan by adding the acquisition date estimate of expected credit losses to the loan's purchase price. The initial ACL for PCD loans of $1.1 billion was established through an adjustment to the BBVA loan balance and related purchase accounting mark. Non-PCD loans and PCD loans had a fair value of $52.1 billion and $9.4 billion at the acquisition date and unpaid principal balance of $52.0 billion and $10.3 billion, respectively. In accordance with U.S. GAAP, there was no carryover of the ACL that had been previously recorded by BBVA. Subsequent to acquisition, PNC recorded an ACL on non-PCD loans of $1.0 billion through an increase to the provision for credit losses.

In May 2020, PNC completed the sale of its 31.6 million shares of BlackRock, Inc. common and preferred stock through a registered secondary offering at a price of $420 per share. In addition, BlackRock repurchased 2.65 million shares from PNC at a price of $414.96 per share. The total proceeds from the sale were $14.2 billion in cash, net of $0.2 billion in expenses, and resulted in a gain on sale of $4.3 billion. Additionally, PNC contributed 500,000 BlackRock shares to the PNC Foundation. Following the sale and donation, PNC has divested its entire investment in BlackRock and only holds shares of BlackRock stock in a fiduciary capacity for clients of PNC.

These amounts are included in Other assets on the Consolidated Balance Sheet. (b) Amortized cost is presented net of allowance of $130 million and $79 million for securities available for sale at September 30, 2021 and December 31, 2020, respectively. (c) Credit ratings represent a primary credit quality indicator used to monitor and manage credit risk. 84% and 85% of our securities held to maturity were rated AAA/AA at September 30, 2021 and December 31, 2020, respectively. The fair value of investment securities is impacted by interest rates, credit spreads, market volatility and liquidity conditions. Securities available for sale are carried at fair value with net unrealized gains and losses included in Shareholders’ equity as AOCI, unless credit related. Net unrealized gains and losses are determined by taking the difference between the fair value of a security and its amortized cost, net of any allowance. Securities held to maturity are carried at amortized cost less any allowance. Investment securities at September 30, 2021 included $2.4 billion of net unsettled purchases which represent non-cash investing activity, and accordingly, are not reflected on the Consolidated Statement of Cash Flows. The comparable amount for September 30, 2020 was $0.7 billion. We maintain the allowance for investment securities at levels that we believe to be appropriate as of the balance sheet date based on estimation of expected credit losses on our portfolio. As of September 30, 2021, the allowance for investment securities was $133 million and primarily related to non-agency commercial mortgage-backed securities in the available for sale portfolio. The provision for credit losses on investment securities was $25 million and $51 million for the three and nine months ended September 30, 2021. See Note 1 Accounting Policies included in Item 8 of our 2020 Form 10-K for a discussion of the methodologies used to determine the allowance for investment securities. Table 43 presents the gross unrealized losses and fair value of securities available for sale that do not have an associated allowance for investment securities at September 30, 2021 and December 31, 2020. These securities are segregated between investments that had been in a continuous unrealized loss position for less than twelve months and twelve months or more, based on the point in time that the fair value declined below the amortized cost basis. All securities included in the table have been evaluated to determine if a credit loss exists. As part of that assessment, as of September 30, 2021, we concluded that we do not intend to sell and believe we will not be required to sell these securities prior to recovery of the amortized cost basis.

Asset Quality [Abstract]
Loans and Related Allowance for Credit Losses	L OANS A ND R ELATED A LLOWANCE F OR C REDIT L OSSES Loan Portfolio Our loan portfolio consists of two portfolio segments – Commercial and Consumer. Each of these segments comprises multiple loan classes. Classes are characterized by similarities in risk attributes and the manner in which we monitor and assess credit risk. Commercial Consumer • Commercial and industrial • Residential real estate • Commercial real estate • Home equity • Equipment lease financing • Automobile • Credit card • Education • Other consumer See Note 1 Accounting Policies included in Item 8 of our 2020 Form 10-K for additional information on our loan related policies. Credit Quality We closely monitor economic conditions and loan performance trends to manage and evaluate our exposure to credit risk within the loan portfolio based on our defined loan classes. In doing so, we use several credit quality indicators, including trends in delinquency rates, nonperforming status, analysis of PD and LGD ratings, updated credit scores, and originated and updated LTV ratios. The measurement of delinquency status is based on the contractual terms of each loan. Loans that are 30 days or more past due in terms of payment are considered delinquent. Loan delinquencies include government insured or guaranteed loans, loans accounted for under the fair value option and PCD loans. Table 47 presents the composition and delinquency status of our loan portfolio at September 30, 2021 and December 31, 2020. Pursuant to the interagency guidance issued in April 2020 and in connection with the credit reporting rules from the CARES Act, the delinquency status of loans modified due to COVID-19 related hardships aligns with the rules set forth for banks to report delinquency status to the credit agencies. These rules require that COVID-19 related loan modifications be reported as follows: • if current at the time of modification, the loan remains current throughout the modification period, • if delinquent at the time of modification and the borrower was not made current as part of the modification, the loan maintains its reported delinquent status during the modification period, or • if delinquent at the time of modification and the borrower was made current as part of the modification or became current during the modification period, the loan is reported as current.

(d) Consumer loans accounted for under the fair value option for which we do not expect to collect substantially all principal and interest are subject to nonaccrual accounting and classification upon meeting any of our nonaccrual policies. Given that these loans are not accounted for at amortized cost, these loans have been excluded from the nonperforming loan population. (e) Includes unearned income, unamortized deferred fees and costs on originated loans, and premiums or discounts on purchased loans totaling $0.9 billion and $1.3 billion at September 30, 2021 and December 31, 2020, respectively. (f) Collateral dependent loans totaled $1.7 billion and $1.5 billion at September 30, 2021 and December 31, 2020, respectively. At September 30, 2021, we pledged $25.6 billion of commercial and other loans to the Federal Reserve Bank and $77.8 billion of residential real estate and other loans to the FHLB as collateral for the ability to borrow, if necessary. The comparable amounts at December 31, 2020 were $30.1 billion and $69.0 billion, respectively. Amounts pledged reflect the unpaid principal balances. Nonperforming Assets Nonperforming assets include nonperforming loans and leases, OREO and foreclosed assets. Nonperforming loans are those loans accounted for at amortized cost whose credit quality has deteriorated to the extent that full collection of contractual principal and interest is not probable and include nonperforming TDRs and PCD loans. Interest income is not recognized on these loans. Loans accounted for under the fair value option are reported as performing loans, however, when nonaccrual criteria is met interest income is not recognized on these loans. Additionally, certain government insured or guaranteed loans for which we expect to collect The following table presents our nonperforming assets as of September 30, 2021 and December 31, 2020 , respectively: Table 48: Nonperforming Assets Dollars in millions September 30 December 31 Nonperforming loans Commercial $ 1,204 $ 923 Consumer (a) 1,324 1,363 Total nonperforming loans (b) 2,528 2,286 OREO and foreclosed assets 31 51 Total nonperforming assets $ 2,559 $ 2,337 Nonperforming loans to total loans 0.87 % 0.94 % Nonperforming assets to total loans, OREO and foreclosed assets 0.88 % 0.97 % Nonperforming assets to total assets 0.46 % 0.50 % (a) Excludes most unsecured consumer loans and lines of credit, which are charged off after 120 to 180 days past due and are not placed on nonperforming status. (b) Nonperforming loans for which there is no related ALLL totaled $1.0 billion at September 30, 2021 and primarily include loans with a fair value of collateral that exceeds the amortized cost basis. The comparable amount at December 31, 2020 was $0.8 billion. Nonperforming loans include certain loans whose terms have been restructured in a manner that grants a concession to a borrower experiencing financial difficulties. In accordance with applicable accounting guidance, these loans are considered TDRs. See Note 1 Accounting Policies included in Item 8 of our 2020 Form 10-K and the Troubled Debt Restructurings section of this Note 4 for additional information on TDRs. Total nonperforming loans in Table 48 include TDRs of $0.8 billion and $0.9 billion at September 30, 2021 and December 31, 2020, respectively.

(b) Represents the amortized cost basis of the loans as of the quarter end prior to TDR designation. (c) Represents the amortized cost basis of the TDRs as of the end of the quarter in which the TDR occurs. After a loan is determined to be a TDR, we continue to track its performance under its most recent restructured terms. We consider a TDR to have subsequently defaulted when it becomes 60 days past due after the most recent date the loan was restructured.

(d) Represents the ALLL plus allowance for unfunded lending related commitments and excludes allowances for investment securities and other financial assets, which together totaled $162 million and $98 million at September 30, 2021 and 2020, respectively. The ACL at September 30, 2021 totaled $6.0 billion, an increase of $0.1 billion since December 31, 2020. This increase was primarily attributable to the addition of reserves related to the BBVA acquisition, partially offset by declines due to portfolio changes and an improved economic outlook. The following summarizes the changes in these factors that influenced the current ACL during the nine months ended September 30, 2021: • Reserves in the current period include expected credit losses on the acquired BBVA loan portfolio. • Portfolio changes that drove reserve declines included improvements in credit quality along with changes in portfolio composition reflecting both shifts in the portfolio mix and declines in certain legacy PNC loan balances.

Loan Sale and Servicing Activities and Variable Interest Entities [Abstract]
Loan Sale and Servicing Activities and Variable Interest Entities	L OAN S ALE AND S ERVICING A CTIVITIES AND V ARIABLE I NTEREST E NTITIES Loan Sale and Servicing Activities As more fully described in Note 5 Loan Sale and Servicing Activities and Variable Interest Entities in Item 8 of our 2020 Form 10-K, we have transferred residential and commercial mortgage loans in securitization or sales transactions in which we have continuing involvement. Our continuing involvement generally consists of servicing, repurchasing previously transferred loans under certain conditions and loss share arrangements, and, in limited circumstances, holding of mortgage-backed securities issued by the securitization SPEs. We earn servicing and other ancillary fees for our role as servicer and, depending on the contractual terms of the servicing arrangement, we can be terminated as servicer with or without cause. At the consummation date of each type of loan transfer where we retain the servicing, we recognize a servicing right at fair value. See Note 8 Commitments and Note 11 Fair Value for information on our servicing rights, including the carrying value of servicing assets. The following table provides cash flows associated with our loan sale and servicing activities: Table 56: Cash Flows Associated with Loan Sale and Servicing Activities In millions Residential Commercial Cash Flows - Three months ended September 30, 2021 Sales of loans (b) $ 2,475 $ 881 Repurchases of previously transferred loans (c) $ 45 $ 103 Servicing fees (d) $ 105 $ 43 Servicing advances recovered/(funded), net $ (4) $ 28 Cash flows on mortgage-backed securities held (e) $ 2,041 $ 18 Cash Flows - Three months ended September 30, 2020 Sales of loans (b) $ 1,799 $ 839 Repurchases of previously transferred loans (c) $ 352 $ 107 Servicing fees (d) $ 85 $ 33 Servicing advances recovered/(funded), net $ (15) $ (78) Cash flows on mortgage-backed securities held (e) $ 2,829 $ 14 Cash Flows - Nine months ended September 30, 2021 Sales of loans (b) $ 5,997 $ 2,604 Repurchases of previously transferred loans (c) $ 189 $ 145 Servicing fees (d) $ 270 $ 119 Servicing advances recovered/(funded), net $ 8 $ (8) Cash flows on mortgage-backed securities held (e) $ 7,256 $ 66 Cash Flows - Nine months ended September 30, 2020 Sales of loans (b) $ 5,328 $ 2,666 Repurchases of previously transferred loans (c) $ 547 $ 132 Servicing fees (d) $ 251 $ 97 Servicing advances recovered/(funded), net $ 4 $ (206) Cash flows on mortgage-backed securities held (e) $ 6,374 $ 65 (a) Represents cash flow information associated with both commercial mortgage loan transfers and servicing activities. (b) Gains/losses recognized on sales of loans were insignificant for the periods presented. (c) Includes both residential and commercial mortgage government insured or guaranteed loans eligible for repurchase through the exercise of our ROAP option, as well as residential mortgage loans repurchased due to alleged breaches of origination covenants or representations and warranties made to purchasers. (d) Includes contractually specified servicing fees, late charges and ancillary fees. (e) Represents cash flows on securities where we transferred to and/or service loans for a securitization SPE and we hold securities issued by that SPE. The carrying values of such securities held were $15.9 billion, $16.5 billion and $19.5 billion in residential mortgage-backed securities and $0.6 billion, $0.8 billion and $0.8 billion in commercial mortgage-backed securities at September 30, 2021, December 31, 2020 and September 30, 2020. Table 57 presents information about the principal balances of transferred loans that we service and are not recorded on our Consolidated Balance Sheet. We would only experience a loss on these transferred loans if we were required to repurchase a loan, where the repurchase price exceeded the loan's fair value, due to a breach in representations and warranties or a loss sharing arrangement associated with our continuing involvement with these loans. The estimate of losses related to breaches in representations and warranties was insignificant at September 30, 2021.

(b) Serviced delinquent loans are 90 days or more past due or are in process of foreclosure. (c) Net charge-offs for Residential mortgages represent credit losses less recoveries distributed and as reported to investors during the period. Net charge-offs for Commercial mortgages represent credit losses less recoveries distributed and as reported by the trustee for commercial mortgage-backed securitizations. Realized losses for Agency securitizations are not reflected as we do not manage the underlying real estate upon foreclosure and, as such, do not have access to loss information. Variable Interest Entities (VIEs) As discussed in Note 5 Loan Sale and Servicing Activities and Variable Interest Entities in Item 8 of our 2020 Form 10-K, we are involved with various entities in the normal course of business that are deemed to be VIEs. The following table provides a summary of non-consolidated VIEs with which we have significant continuing involvement but are not the primary beneficiary. We have excluded certain transactions with non-consolidated VIEs from the balances presented in Table 58 where we have determined that our continuing involvement is not significant. We do not consider our continuing involvement to be significant when it relates to a VIE where we only invest in securities issued by the VIE and were not involved in the design of the VIE or where no transfers have occurred between us and the VIE. In addition, where we only have lending arrangements in the normal course of business with entities that could be VIEs, we have excluded these transactions with non-consolidated entities from the balances presented in Table 58. These loans are included as part of the asset quality disclosures that we make in Note 4 Loans and Related Allowance for Credit Losses.

The risk of loss excludes any potential tax recapture associated with tax credit investments. (b) Amounts reflect involvement with securitization SPEs where we transferred to and/or service loans for an SPE and we hold securities issued by that SPE. Values disclosed in the PNC Risk of Loss column represent our maximum exposure to loss for those securities’ holdings. (c) Included in Investment securities, Mortgage servicing rights and Other assets on our Consolidated Balance Sheet. (d) Included in Investment securities, Loans, Equity investments and Other assets on our Consolidated Balance Sheet. (e) Included in Deposits and Other liabilities on our Consolidated Balance Sheet. We make certain equity investments in various tax credit limited partnerships or LLCs. The purpose of these investments is to achieve a satisfactory return on capital and to assist us in achieving goals associated with the CRA. Within Income taxes, during both the nine months ended September 30, 2021 and September 30, 2020, we recognized $0.1 billion or less of amortization, tax credits and other tax benefits associated with qualified investments in low income housing tax credits.

Goodwill and Mortgage Servicing

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Mortgage Servicing Rights	G OODWILL AND M ORTGAGE S ERVICING R IGHTS Allocations of Goodwill by business segment during 2021 and 2020 follow: Table 59: Goodwill by Business Segment In millions Retail Banking Corporate & Institutional Banking Asset Management Group Total September 30, 2021 (a) $ 6,459 $ 4,239 $ 187 $ 10,885 December 31, 2020 $ 5,795 $ 3,374 $ 64 $ 9,233 (a) Includes $1.6 billion of goodwill from the BBVA acquisition. Goodwill increased during the nine months ended September 30, 2021 primarily as a result of the acquisition of BBVA. Goodwill was recorded and allocated to each segment on a preliminary basis and is subject to change based on new information obtained related to the close date or reallocation of assets and liabilities to each segment. See Note 2 Acquisition and Divestiture Activities for additional information. We review goodwill in each of our reporting units for impairment at least annually, in the fourth quarter, or more frequently if events occur or circumstances have changed significantly from the annual test date. Based on results of our review for triggering events, there were no impairment charges related to goodwill in the first nine months of 2021 or in 2020. Mortgage Servicing Rights We recognize the right to service mortgage loans for others as an intangible asset when the servicing income we receive is more than our projected servicing costs. MSRs are purchased or originated when loans are sold with servicing retained. MSRs totaled $1.8 billion and $1.2 billion at September 30, 2021 and December 31, 2020, respectively, and consisted of loan servicing contracts for commercial and residential mortgages measured at fair value. MSRs are subject to declines in value from actual or expected prepayment of the underlying loans and defaults, as well as market driven changes in interest rates. We manage this risk by economically hedging the fair value of MSRs with securities and derivative instruments which are expected to increase (or decrease) in value when the value of MSRs decreases (or increases). See the Sensitivity Analysis section of this Note 6 for more detail on our fair value measurement of MSRs. See Note 15 Fair Value and Note 6 Goodwill and Mortgage Servicing Rights in the Notes to Consolidated Financial Statements included in Item 8 of our 2020 Form 10-K for more detail on our fair value measurement and our accounting of MSRs. Changes in the commercial and residential MSRs follow: Table 60: Mortgage Servicing Rights Commercial MSRs Residential MSRs In millions 2021 2020 2021 2020 January 1 $ 569 $ 649 $ 673 $ 995 Additions: BBVA Acquisition 35 From loans sold with servicing retained 61 65 61 34 Purchases 26 31 400 113 Changes in fair value due to: Time and payoffs (a) (87) (87) (242) (136) Other (b) 134 (143) 203 (408) September 30 $ 703 $ 515 $ 1,130 $ 598 Related unpaid principal balance at September 30 $ 263,862 $ 234,897 $ 139,154 $ 119,158 Servicing advances at September 30 $ 445 $ 363 $ 139 $ 107 (a) Represents decrease in MSR value due to passage of time, including the impact from both regularly scheduled loan principal payments and loans that were paid down or paid off during the period. (b) Represents MSR value changes resulting primarily from market-driven changes in interest rates. Sensitivity Analysis The fair value of commercial and residential MSRs and significant inputs to the valuation models as of September 30, 2021 and December 31, 2020 are shown in Tables 61 and 62. The expected and actual rates of mortgage loan prepayments are significant factors driving the fair value. Management uses both internal proprietary models and a third-party model to estimate future commercial mortgage loan prepayments and a third-party model to estimate future residential mortgage loan prepayments. These models have been refined based on current market conditions and management judgment. Future interest rates are another important factor in the valuation of MSRs. Management utilizes market implied forward interest rates to estimate the future direction of mortgage and discount rates. The forward rates utilized are derived from the current yield curve for U.S. dollar interest rate swaps and are consistent with pricing of capital markets instruments. Changes in the shape and slope of the forward curve in future periods may result in volatility in the fair value estimate. A sensitivity analysis of the hypothetical effect on the fair value of MSRs to adverse changes in key assumptions is presented in Tables 61 and 62. These sensitivities do not include the impact of the related hedging activities. Changes in fair value generally cannot be extrapolated because the relationship of the change in the assumption to the change in fair value may not be linear. Also, the effect of a variation in a particular assumption on the fair value of the MSRs is calculated independently without changing any other assumption. In reality, changes in one factor may result in changes in another ( e.g. , changes in mortgage interest rates, which drive changes in prepayment rate estimates, could result in changes in the interest rate spread), which could either magnify or counteract the sensitivities. The following tables set forth the fair value of commercial and residential MSRs and the sensitivity analysis of the hypothetical effect on the fair value of MSRs to immediate adverse changes of 10% and 20% in those assumptions. Table 61: Commercial Mortgage Servicing Rights – Key Valuation Assumptions Dollars in millions September 30 December 31 Fair value $ 703 $ 569 Weighted-average life (years) 4.4 4.4 Weighted-average constant prepayment rate 5.46 % 4.87 % Decline in fair value from 10% adverse change $ 10 $ 9 Decline in fair value from 20% adverse change $ 20 $ 18 Effective discount rate 7.55 % 7.33 % Decline in fair value from 10% adverse change $ 19 $ 15 Decline in fair value from 20% adverse change $ 39 $ 31 Table 62: Residential Mortgage Servicing Rights – Key Valuation Assumptions Dollars in millions September 30 December 31 Fair value $ 1,130 $ 673 Weighted-average life (years) 5.9 3.8 Weighted-average constant prepayment rate 11.49 % 21.13 % Decline in fair value from 10% adverse change $ 47 $ 41 Decline in fair value from 20% adverse change $ 94 $ 82 Weighted-average option adjusted spread 909 bps 922 bps Decline in fair value from 10% adverse change $ 37 $ 20 Decline in fair value from 20% adverse change $ 72 $ 38 Fees from mortgage loan servicing, which includes contractually specified servicing fees, late fees and ancillary fees were $0.2 billion for the three months ended September 30, 2021 and 2020 and $0.4 billion for the nine months ended September 30, 2021 and 2020. We also generate servicing fees from fee-based activities provided to others for which we do not have an associated servicing asset. Fees from commercial and residential MSRs are reported within Noninterest income on our Consolidated Income Statement in Corporate services and Residential mortgage, respectively.

(b) We enter into standby bond purchase agreements to support municipal bond obligations. (c) Includes $1.7 billion and $1.1 billion related to investments in qualified affordable housing projects for September 30, 2021 and December 31, 2020, respectively. Commitments to Extend Credit Commitments to extend credit, or net unfunded loan commitments, represent arrangements to lend funds or provide liquidity subject to specified contractual conditions. These commitments generally have fixed expiration dates, may require payment of a fee, and generally contain termination clauses in the event the customer’s credit quality deteriorates. Net Outstanding Standby Letters of Credit We issue standby letters of credit and share in the risk of standby letters of credit issued by other financial institutions, in each case to support obligations of our customers to third parties, such as insurance requirements and the facilitation of transactions involving capital markets product execution. Approximately 97% of our net outstanding standby letters of credit were rated as Pass as of September 30, 2021, with the remainder rated as Criticized. An internal credit rating of Pass indicates the expected risk of loss is currently low, while a rating of Criticized indicates a higher degree of risk. If the customer fails to meet its financial or performance obligation to the third party under the terms of the contract or there is a need to support a remarketing program, then upon a draw by a beneficiary, subject to the terms of the letter of credit, we would be obligated to make payment to them. The standby letters of credit outstanding on September 30, 2021 had terms ranging from less than one year to eight years.

Fair Value

Fair Value [Abstract]
Fair Value	F AIR V ALUE Fair Value Measurement We measure certain financial assets and liabilities at fair value. Fair value is defined as the price that would be received to sell an asset or the price that would be paid to transfer a liability on the measurement date, and is determined using an exit price in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants. The fair value hierarchy established by GAAP requires us to maximize the use of observable inputs when measuring fair value. For more information regarding the fair value hierarchy, see Note 15 Fair Value in Item 8 of our 2020 Form 10-K. Additionally, for more information regarding the fair value of assets and liabilities from our BBVA acquisition, see Note 2 Acquisition and Divestiture Activity in this Report. Assets and Liabilities Measured at Fair Value on a Recurring Basis For more information on the valuation methodologies used to measure assets and liabilities at fair value on a recurring basis, see Note 15 Fair Value in Item 8 of our 2020 Form 10-K. The following table summarizes our assets and liabilities measured at fair value on a recurring basis, including instruments for which we have elected the fair value option.

(b) The difference in unrealized gains and losses for the period included in Other comprehensive income and changes in unrealized gains and losses for the period included in Other comprehensive income for securities available for sale held at the end of the reporting period were not significant. (c) The amount of the total gains or losses for the period included in earnings that is attributable to the change in unrealized gains or losses related to those assets and liabilities held at the end of the reporting period. (d) Upon adoption of ASU 2016-13 - Credit Losses , we discontinued the accounting for purchased impaired loans and elected the one-time fair value option election for some of these loans and certain nonperforming loans. (e) Residential mortgage loan transfers out of Level 3 are primarily driven by residential mortgage loans transferring to OREO as well as reclassification of mortgage loans held for sale to held for investment. (f) Net gains (losses) realized and unrealized included in earnings related to Level 3 assets and liabilities included amortization and accretion. The amortization and accretion amounts were included in Interest income on the Consolidated Income Statement and the remaining net gains (losses) realized and unrealized were included in Noninterest income on the Consolidated Income Statement. (g) Net unrealized gains (losses) related to assets and liabilities held at the end of the reporting period were included in Noninterest income on the Consolidated Income Statement. An instrument’s categorization within the hierarchy is based on the lowest level of input that is significant to the fair value measurement. Changes from one quarter to the next related to the observability of inputs to a fair value measurement may result in a reclassification (transfer) of assets or liabilities between hierarchy levels. Quantitative information about the significant unobservable inputs within Level 3 recurring assets and liabilities follows: Table 72: Fair Value Measurements – Recurring Quantitative Information September 30, 2021 Level 3 Instruments Only Fair Value Valuation Techniques Unobservable Inputs Range (Weighted-Average) (a) Commercial mortgage loans held for sale $ 51 Discounted cash flow Spread over the benchmark curve (b) 610bps - 10,580bps (2,442bps) Residential mortgage-backed 1,168 Priced by a third-party vendor using a discounted cash flow pricing model Constant prepayment rate 1.0% - 30.7% (11.2%) Constant default rate 0.0% - 16.9% (4.6%) Loss severity 20.0% - 95.7% (47.7%) Spread over the benchmark curve (b) 160bps weighted-average Asset-backed securities 172 Priced by a third-party vendor using a discounted cash flow pricing model Constant prepayment rate 1.0% - 40.0% (10.5%) Constant default rate 1.4% - 20.0% (3.3%) Loss severity 8.0% - 100.0% (52.1%) Spread over the benchmark curve (b) 198bps weighted-average Loans - Residential real estate 640 Consensus pricing (c) Cumulative default rate 3.6% - 100.0% (77.2%) Loss severity 0.0% - 100.0% (8.9%) Discount rate 4.8% - 6.8% (5.1%) 116 Discounted cash flow Loss severity 8.0% weighted-average Discount rate 3.2% weighted-average Loans - Home equity 18 Consensus pricing (c) Cumulative default rate 3.6% -100.0% (83.9%) Loss severity 0.0% - 98.4% (29.6%) Discount rate 4.8% - 6.8% (6.2%) 162 Consensus pricing (c) Credit and liquidity discount 0.0% - 100.0% (23.1%) Equity investments 1,530 Multiple of adjusted earnings Multiple of earnings 5.0x - 14.8x (9.0x) Residential mortgage servicing rights 1,130 Discounted cash flow Constant prepayment rate 0.0% - 40.0% (11.5%) Spread over the benchmark curve (b) 380bps - 2,271bps (909bps) Commercial mortgage servicing rights 703 Discounted cash flow Constant prepayment rate 4.9% - 13.9% (5.5%) Discount rate 5.3% - 7.8% (7.6%) Financial derivatives - Swaps related to (314) Discounted cash flow Estimated conversion factor of Visa Class B shares into Class A shares 162.3% weighted-average Estimated annual growth rate of Visa Class A share price 16.0% Estimated length of litigation resolution date Q2 2023 Insignificant Level 3 assets, net of 26 Total Level 3 assets, net of liabilities (e) $ 5,402 (continued from previous page) December 31, 2020 Level 3 Instruments Only Fair Value Valuation Techniques Unobservable Inputs Range (Weighted-Average) (a) Commercial mortgage loans held for sale $ 57 Discounted cash flow Spread over the benchmark curve (b) 630bps - 5,275bps (3,406bps) Residential mortgage-backed 1,365 Priced by a third-party vendor using a discounted cash flow pricing model Constant prepayment rate 1.0% - 37.6% (8.6%) Constant default rate 0.0% - 12.2% (4.7%) Loss severity 25.0% - 95.7% (48.8%) Spread over the benchmark curve (b) 242bps weighted-average Asset-backed securities 199 Priced by a third-party vendor using a discounted cash flow pricing model Constant prepayment rate 1.0% -22.0% (7.4%) Constant default rate 1.0% - 6.0% (3.3%) Loss severity 30.0% - 100.0% (58.1%) Spread over the benchmark curve (b) 291bps weighted-average Loans - Residential real estate 434 Consensus pricing (c) Cumulative default rate 3.6% - 100.0% (82.1%) Loss severity 0.0% - 100.0% (11.2%) Discount rate 4.8% - 6.8% (5.1%) 132 Discounted cash flow Loss severity 8.0% weighted-average Discount rate 3.2% weighted-average Loans - Home equity 21 Consensus pricing (c) Cumulative default rate 3.6% - 100.0% (88.5%) Loss severity 0.0% - 98.4% (33.3%) Discount rate 4.8% - 6.8% (6.3%) 60 Consensus pricing (c) Credit and Liquidity discount 17.5% - 97.0% (57.7%) Equity investments 1,263 Multiple of adjusted earnings Multiple of earnings 5.0x - 15.9x (8.7x) Residential mortgage servicing rights 673 Discounted cash flow Constant prepayment rate 0.0% - 77.5% (21.1%) Spread over the benchmark curve (b) 325bps - 2,783bps (922bps) Commercial mortgage servicing rights 569 Discounted cash flow Constant prepayment rate 4.0% - 16.1% (4.9%) Discount rate 4.7% - 7.8% (7.3%) Financial derivatives - Swaps related to (252) Discounted cash flow Estimated conversion factor of Visa Class B shares into Class A shares 162.3% weighted-average Estimated annual growth rate of Visa Class A share price 16.0% Estimated length of litigation Q2 2022 Insignificant Level 3 assets, net of 298 Total Level 3 assets, net of liabilities (e) $ 4,819 (a) Unobservable inputs were weighted by the relative fair value of the instruments.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Financial Derivatives	F INANCIAL D ERIVATIVES We use a variety of financial derivatives to both mitigate exposure to market (primarily interest rate) and credit risks inherent in our business activities, as well as to facilitate customer risk management activities. We manage these risks as part of our overall asset and liability management process and through our credit policies and procedures. Derivatives represent contracts between parties that usually require little or no initial net investment and result in one party delivering cash or another type of asset to the other party based on a notional amount and an underlying as specified in the contract. Derivative transactions are often measured in terms of notional amount, but this amount is generally not exchanged and it is not recorded on the balance sheet. The notional amount is the basis to which the underlying is applied to determine required payments under the derivative contract. The underlying is a referenced interest rate, security price, credit spread or other index. Residential and commercial real estate loan commitments associated with loans to be sold also qualify as derivative instruments. For more information regarding derivatives see Note 1 Accounting Policies and Note 16 Financial Derivatives in the Notes to Consolidated Financial Statements included in Item 8 of our 2020 Form 10-K. The following table presents the notional and gross fair value amounts of all derivative assets and liabilities held by us: Table 77: Total Gross Derivatives (a) September 30, 2021 December 31, 2020 In millions Notional / Asset Fair Liability Fair Notional / Asset Fair Liability Fair Derivatives used for hedging Interest rate contracts (d): Fair value hedges $ 24,837 $ 24,153 Cash flow hedges 42,018 $ 12 $ 38 22,875 $ 14 Foreign exchange contracts: Net investment hedges 1,148 1 3 1,075 $ 22 Total derivatives designated for hedging $ 68,003 $ 13 $ 41 $ 48,103 $ 14 $ 22 Derivatives not used for hedging Derivatives used for mortgage banking activities (e): Interest rate contracts: Swaps $ 33,994 $ 50,511 Futures (f) 3,666 2,841 Mortgage-backed commitments 13,702 $ 98 $ 54 11,288 $ 147 $ 77 Other 13,732 38 11 1,831 11 2 Total interest rate contracts 65,094 136 65 66,471 158 79 Derivatives used for customer-related activities: Interest rate contracts: Swaps 304,724 3,961 1,508 280,125 5,475 1,601 Futures (f) 1,006 1,235 Mortgage-backed commitments 4,692 18 16 4,178 11 14 Other 25,333 143 88 20,125 193 88 Total interest rate contracts 335,755 4,122 1,612 305,663 5,679 1,703 Commodity contracts: Swaps 9,249 2,099 2,114 6,149 350 323 Other 3,236 422 422 2,770 61 61 Total commodity contracts 12,485 2,521 2,536 8,919 411 384 Foreign exchange contracts and other 27,995 192 182 26,620 267 243 Total derivatives for customer-related activities 376,235 6,835 4,330 341,202 6,357 2,330 Derivatives used for other risk management activities: Foreign exchange contracts and other 12,782 51 345 10,931 4 325 Total derivatives not designated for hedging $ 454,111 $ 7,022 $ 4,740 $ 418,604 $ 6,519 $ 2,734 Total gross derivatives $ 522,114 $ 7,035 $ 4,781 $ 466,707 $ 6,533 $ 2,756 Less: Impact of legally enforceable master netting agreements 1,027 1,027 720 720 Less: Cash collateral received/paid 757 2,403 1,434 1,452 Total derivatives $ 5,251 $ 1,351 $ 4,379 $ 584 (a) Centrally cleared derivatives are settled in cash daily and result in no derivative asset or derivative liability being recognized on our Consolidated Balance Sheet .

(e) Includes both residential and commercial mortgage banking activities. (f) Futures contracts are settled in cash daily and result in no derivative asset or derivative liability being recognized on our Consolidated Balance Sheet. All derivatives are carried on our Consolidated Balance Sheet at fair value. Derivative balances are presented on the Consolidated Balance Sheet on a net basis taking into consideration the effects of legally enforceable master netting agreements and, when appropriate, any related cash collateral exchanged with counterparties. Further discussion regarding the offsetting rights associated with these legally enforceable master netting agreements is included in the Offsetting, Counterparty Credit Risk and Contingent Features section of this Note 12. Any nonperformance risk, including credit risk, is included in the determination of the estimated net fair value of the derivatives. Derivatives Designated As Hedging Instruments Certain derivatives used to manage interest rate and foreign exchange risk as part of our asset and liability risk management activities are designated as accounting hedges. Derivatives hedging the risks associated with changes in the fair value of assets or liabilities are considered fair value hedges, derivatives hedging the variability of expected future cash flows are considered cash flow hedges and derivatives hedging a net investment in a foreign subsidiary are considered net investment hedges. Designating derivatives as accounting hedges allows for gains and losses on those derivatives to be recognized in the same period and in the same income statement line item as the earnings impact of the hedged items. Fair Value Hedges We enter into receive-fixed, pay-variable interest rate swaps to hedge changes in the fair value of outstanding fixed-rate debt caused by fluctuations in market interest rates. We also enter into pay-fixed, receive-variable interest rate swaps and zero-coupon swaps to hedge changes in the fair value of fixed rate and zero-coupon investment securities caused by fluctuations in market interest rates. Gains and losses on the interest rate swaps designated in these hedge relationships, along with the offsetting gains and losses on the hedged items attributable to the hedged risk, are recognized in current earnings within the same income statement line item. Cash Flow Hedges We enter into receive-fixed, pay-variable interest rate swaps and interest rate caps and floors to modify the interest rate characteristics of designated commercial loans from variable to fixed in order to reduce the impact of changes in future cash flows due to market interest rate changes. We also periodically enter into forward purchase and sale contracts to hedge the variability of the consideration that will be paid or received related to the purchase or sale of investment securities. The forecasted purchase or sale is consummated upon gross settlement of the forward contract itself. For these cash flow hedges, gains and losses on the hedging instruments are recorded in AOCI and are then reclassified into earnings in the same period the hedged cash flows affect earnings and within the same income statement line as the hedged cash flows. In the 12 months that follow September 30, 2021, we expect to reclassify net derivative gains of $312 million pretax, or $240 million after-tax, from AOCI to interest income for these cash flow hedge strategies. This reclassified amount could differ from amounts actually recognized due to changes in interest rates, hedge de-designations, and the addition of other hedges subsequent to September 30, 2021. As of September 30, 2021, the maximum length of time over which forecasted transactions are hedged is ten years. Further detail regarding gains (losses) related to our fair value and cash flow hedge derivatives is presented in the following table: Table 78: Gains (Losses) Recognized on Fair Value and Cash Flow Hedges in the Consolidated Income Statement (a) (b) Location and Amount of Gains (Losses) Recognized in Income Interest Income Interest Expense Noninterest Income In millions Loans Investment Securities Borrowed Funds Other For the three months ended September 30, 2021 Total amounts on the Consolidated Income Statement $ 2,437 $ 460 $ 90 $ 449 Gains (losses) on fair value hedges recognized on: Hedged items (c) $ 2 $ 155 Derivatives $ (169) Amounts related to interest settlements on derivatives $ (1) $ 129 Gains (losses) on cash flow hedges (d): Amount of derivative gains (losses) reclassified from AOCI $ 91 $ 11 $ 13 For the three months ended September 30, 2020 Total amounts on the Consolidated Income Statement $ 2,116 $ 490 $ 118 $ 457 Gains (losses) on fair value hedges recognized on: Hedged items (c) $ (13) $ 141 Derivatives $ 14 $ (166) Amounts related to interest settlements on derivatives $ (3) $ 149 Gains (losses) on cash flow hedges (d): Amount of derivative gains (losses) reclassified from AOCI $ 118 $ 16 For the nine months ended September 30, 2021 Total amounts on the Consolidated Income Statement $ 6,593 $ 1,350 $ 275 $ 1,400 Gains (losses) on fair value hedges recognized on: Hedged items (c) $ (3) $ 695 Derivatives $ 7 $ (740) Amounts related to interest settlements on derivatives $ (3) $ 394 Gains (losses) on cash flow hedges (d): Amount of derivative gains (losses) reclassified from AOCI $ 282 $ 49 $ 27 For the nine months ended September 30, 2020 Total amounts on the Consolidated Income Statement $ 6,853 $ 1,599 $ 619 $ 1,071 Gains (losses) on fair value hedges recognized on: Hedged items (c) $ 224 $ (1,300) Derivatives $ (219) $ 1,220 Amounts related to interest settlements on derivatives $ (7) $ 341 Gains (losses) on cash flow hedges (d): Amount of derivative gains (losses) reclassified from AOCI $ 262 $ 19 $ 1 (a) For all periods presented, there were no components of derivative gains or losses excluded from the assessment of hedge effectiveness for any of the fair value or cash flow hedge strategies. (b) All cash flow and fair value hedge derivatives were interest rate contracts for the periods presented. (c) Includes an insignificant amount of fair value hedge adjustments related to discontinued hedge relationships. Detail regarding the impact of fair value hedge accounting on the carrying value of the hedged items is presented in the following table: Table 79: Hedged Items - Fair Value Hedges September 30, 2021 December 31, 2020 In millions Carrying Value of the Hedged Items Cumulative Fair Value Hedge Adjustment included in the Carrying Value of Hedged Items (a) Carrying Value of the Hedged Items Cumulative Fair Value Hedge Adjustment included in the Carrying Value of Hedged Items (a) Investment securities - available for sale (b) $ 2,905 $ 25 $ 2,785 $ 30 Borrowed funds $ 25,924 $ 906 $ 25,797 $ 1,611 (a) Includes $(0.1) billion of fair value hedge adjustments primarily related to discontinued borrowed funds hedge relationships at both September 30, 2021 and December 31, 2020, respectively. (b) Carrying value shown represents amortized cost. Net Investment Hedges We enter into foreign currency forward contracts to hedge non-U.S. dollar net investments in foreign subsidiaries against adverse changes in foreign exchange rates. We assess whether the hedging relationship is highly effective in achieving offsetting changes in the value of the hedge and hedged item by qualitatively verifying that the critical terms of the hedge and hedged item match at the inception of the hedging relationship and on an ongoing basis. Net investment hedge derivatives are classified as foreign exchange contracts. There were no components of derivative gains or losses excluded from the assessment of the hedge effectiveness for all periods presented. Net gains (losses) on net investment hedge derivatives recognized in OCI were $28 million and $20 million for the three and nine months ended September 30, 2021, compared with $(42) million and $38 million for the same periods in 2020, respectively. Derivatives Not Designated As Hedging Instruments For additional information on derivatives not designated as hedging instruments under GAAP, see Note 16 Financial Derivatives in the Notes to Consolidated Financial Statements included in Item 8 of our 2020 Form 10-K.

(b) Included in Other noninterest income on our Consolidated Income Statement. Offsetting, Counterparty Credit Risk and Contingent Features We generally utilize a net presentation on the Consolidated Balance Sheet for those derivative financial instruments entered into with counterparties under legally enforceable master netting agreements. The master netting agreements reduce credit risk by permitting the closeout netting of all outstanding derivative instruments under the master netting agreement with the same counterparty upon the occurrence of an event of default. The master netting agreement also may require the exchange of cash or marketable securities to collateralize either party’s net position. For additional information on derivative offsetting, counterparty credit risk and contingent features, see Note 16 Financial Derivatives in the Notes to Consolidated Financial Statements included in Item 8 of our 2020 Form 10-K. Table 81 shows the impact legally enforceable master netting agreements had on our derivative assets and derivative liabilities as of September 30, 2021 and December 31, 2020. The table includes cash collateral held or pledged under legally enforceable master netting agreements. The table also includes the fair value of any securities collateral held or pledged under legally enforceable master netting agreements. Cash and securities collateral amounts are included in the table only to the extent of the related net derivative fair values.

(b) Represents the net amount of derivative liabilities included in Other liabilities on our Consolidated Balance Sheet. In addition to using master netting agreements and other collateral agreements to reduce credit risk associated with derivative instruments, we also seek to manage credit risk by evaluating credit ratings of counterparties and by using internal credit analysis, limits and monitoring procedures. At September 30, 2021, we held cash and debt securities (primarily agency mortgage-backed securities) totaling $1.6 billion under master netting agreements and other collateral agreements to collateralize net derivative assets due from counterparties, and we pledged cash totaling $3.4 billion under these agreements to collateralize net derivative liabilities owed to counterparties and to meet initial margin requirements. These totals may differ from the amounts presented in the preceding offsetting table because these totals may include collateral exchanged under an agreement that does not qualify as a master netting agreement or because the total amount of collateral held or pledged exceeds the net derivative fair values with the counterparty as of the balance sheet date due to timing or other factors, such as initial margin. To the extent not netted against the derivative fair values under a master netting agreement, the receivable for cash pledged is included in Other assets and the obligation for cash held is included in Other liabilities on our Consolidated Balance Sheet. Securities held from counterparties are not recognized on our balance sheet. Likewise securities we have pledged to counterparties remain on our balance sheet.

Legal Proceedings [Abstract]
Legal Proceedings	L EGAL P ROCEEDINGS We establish accruals for legal proceedings, including litigation and regulatory and governmental investigations and inquiries, when information related to the loss contingencies represented by those matters indicates both that a loss is probable and that the amount of loss can be reasonably estimated. Any such accruals are adjusted thereafter as appropriate to reflect changed circumstances. When we are able to do so, we also determine estimates of possible losses or ranges of possible losses, whether in excess of any related accrued liability or where there is no accrued liability, for disclosed legal proceedings (“Disclosed Matters,” which are those matters disclosed in this Note 13 as well as those matters disclosed in Note 21 Legal Proceedings in Part II, Item 8 of our 2020 Form 10-K and in Note 13 Legal Proceedings in Part I, Item 1 of our first and second quarter 2021 Form 10-Q (such prior disclosure referred to as “Prior Disclosure”)). For Disclosed Matters where we are able to estimate such possible losses or ranges of possible losses, as of September 30, 2021, we estimate that it is reasonably possible that we could incur losses in excess of related accrued liabilities, if any, in an aggregate amount less than $100 million. The estimates included in this amount are based on our analysis of currently available information and are subject to significant judgment and a variety of assumptions and uncertainties. As new information is obtained we may change our estimates. Due to the inherent subjectivity of the assessments and unpredictability of outcomes of legal proceedings, any amounts accrued or included in this aggregate amount may not represent the ultimate loss to us from the legal proceedings in question. Thus, our exposure and ultimate losses may be higher, and possibly significantly so, than the amounts accrued or this aggregate amount. As a result of the types of factors described in Note 21 Legal Proceedings in Part II, Item 8 of our 2020 Form 10-K, we are unable, at this time, to estimate the losses that are reasonably possible to be incurred or ranges of such losses with respect to some of the matters disclosed, and the aggregate estimated amount provided above does not include an estimate for every Disclosed Matter. Therefore, as the estimated aggregate amount disclosed above does not include all of the Disclosed Matters, the amount disclosed above does not represent our maximum reasonably possible loss exposure for all of the Disclosed Matters. The estimated aggregate amount also does not reflect any of our exposure to matters not so disclosed, as discussed below under “Other.” We include in some of the descriptions of individual Disclosed Matters certain quantitative information related to the plaintiff’s claim against us as alleged in the plaintiff’s pleadings or other public filings or otherwise publicly available information. While information of this type may provide insight into the potential magnitude of a matter, it does not necessarily represent our estimate of reasonably possible loss or our judgment as to any currently appropriate accrual. Some of our exposure in Disclosed Matters may be offset by applicable insurance coverage. We do not consider the possible availability of insurance coverage in determining the amounts of any accruals (although we record the amount of related insurance recoveries that are deemed probable up to the amount of the accrual) or in determining any estimates of possible losses or ranges of possible losses. Pre-need Funeral Arrangements National City Bank and PNC Bank (collectively, "the PNC defendants") were defendants in a lawsuit filed in the U.S. District Court for the Eastern District of Missouri under the caption Jo Ann Howard and Associates, P.C., et al. v. Cassity, et al (No. 4:09-CV-1252-ERW) arising out of trustee services provided by Allegiant Bank, a National City Bank and PNC Bank predecessor, with respect to Missouri trusts that held pre-need funeral contract assets. In July 2019, following a new trial on remand from the court of appeals, the district court awarded the plaintiffs $72 million in compensatory damages, $15 million in interest, and $15 million in punitive damages. The PNC defendants appealed this judgment to the court of appeals, and the plaintiffs cross-appealed. In December 2019, the court reduced the judgment by approximately $2.6 million to correct a mathematical error in calculating pre-judgment interest, reducing the total judgment to $99.5 million. In March 2020, the court dismissed the plaintiffs’ cross-appeal on the plaintiffs’ motion. In February 2020, the district court awarded $7 million in fees and costs to the plaintiffs, and the PNC defendants appealed this judgment to the court of appeals. The consolidated appeals of the district court’s judgments were argued in January 2021. In August 2021, the court of appeals affirmed the judgment of the district court. The PNC defendants paid the judgment and a satisfaction of judgment was filed by plaintiffs with the district court. USAA Patent Infringement Litigation In September 2021, in United Services Automobile Association v. PNC Bank N.A . (Case No. 2:20-cv-319), pending in the United States District Court for the Eastern District of Texas (“the first Texas case”), the Court denied our motion to dismiss and our motion to transfer the case. In April 2021, in United Services Automobile Association v. PNC Bank N.A. (Case No. 2:21-cv-110), pending in the United States District Court for the Eastern District of Texas, we moved to consolidate this action with the first Texas case and we filed motions to dismiss and transfer this action. In July 2021, this action was consolidated with the first Texas case. In September 2021, the Court denied our motion to dismiss and our motion to transfer, for the same reasons set forth in its September 2021 orders in the first Texas case. Trial in the two consolidated cases is presently scheduled to commence on April 18, 2022. In July 2021, in United Services Automobile Association v. PNC Bank N.A (case No. 2:21-cv-246), pending in the United States District Court for the Eastern District of Texas, we filed motions to dismiss and transfer this action. In August 2021, USAA filed a lawsuit, United Services Automobile Association v. BBVA USA (Case No. 2:21-cv-311), in the United States District Court for the Eastern District of Texas against BBVA USA for patent infringement. The complaint alleges that BBVA USA’s remote deposit capture systems infringe six patents owned by the plaintiff. The plaintiff seeks, among other things, a judgment that BBVA USA is infringing each of the patents, damages for willful infringement and attorneys’ fees. In October 2021, BBVA USA was merged into PNC Bank. Also in October 2021, we answered the complaint and asserted counterclaims for a declaratory judgment that the asserted patents are invalid and not infringed. Other Regulatory and Governmental Inquiries We are the subject of investigations, audits, examinations and other forms of regulatory and governmental inquiry covering a broad range of issues in our consumer, mortgage, brokerage, securities and other financial services businesses, as well as other aspects of our operations. In some cases, these inquiries are part of review of specified activities at multiple industry participants; in others, they are directed at PNC individually. From time to time, these inquiries have involved and may in the future involve or lead to regulatory enforcement actions and other administrative proceedings. These inquiries have also led to and may in the future lead to civil or criminal judicial proceedings. Some of these inquiries result in remedies including fines, penalties, restitution, or alterations in our business practices, and in additional expenses and collateral costs and other consequences. Such remedies and other consequences typically have not been material to us from a financial standpoint but could be in the future. Even if not material, they may result in significant reputational harm or other adverse consequences. Our practice is to cooperate fully with regulatory and governmental investigations, audits and other inquiries, including those described in Prior Disclosure. Other In addition to the proceedings or other matters described in Prior Disclosure, PNC and persons to whom we may have indemnification obligations, in the normal course of business, are subject to various other pending and threatened legal proceedings in which claims for monetary damages and other relief are asserted. We do not anticipate, at the present time, that the ultimate aggregate liability, if any, arising out of such other legal proceedings will have a material adverse effect on our financial position. However, we cannot now determine whether or not any claims asserted against us or others to whom we may have indemnification obligations, whether in the proceedings or other matters described above or otherwise, will have a material adverse effect on our results of operations in any future reporting period, which will depend on, among other things, the amount of the loss resulting from the claim and the amount of income otherwise reported for the reporting period.

Segment Reporting

Segment Reporting [Abstract]
Segment Reporting	S EGMENT R EPORTING We have three reportable business segments: • Retail Banking • Corporate & Institutional Banking • Asset Management Group Results of individual businesses are presented based on our internal management reporting practices. There is no comprehensive, authoritative body of guidance for management accounting equivalent to GAAP; therefore, the financial results of our individual businesses are not necessarily comparable with similar information for any other company. We periodically refine our internal methodologies as management reporting practices are enhanced. To the extent significant and practicable, retrospective application of new methodologies is made to prior period reportable business segment results and disclosures to create comparability with the current period. Our third quarter 2021 business segment results reflect the full quarter of BBVA's business operations, while results for the nine months ended September 2021 also include the impact of BBVA for the month of June. Until conversion of bank systems and branches as of October 12, 2021, PNC Bank and BBVA customers were served through their respective PNC Bank and BBVA branches, websites and mobile apps, financial advisors and relationship managers. Following conversion, there will be changes in the segmentation of BBVA USA customers as we continue to integrate data to PNC applications, finalize the review of customer relationships and better align customers with PNC's products and services. These changes will be reflected in fourth quarter reporting. See Note 2 Acquisition and Divestiture Activity for additional information on the acquisition of BBVA. During the second quarter of 2020, we divested our entire 22.4% investment in BlackRock, which had previously been reported as a separate business segment. See Note 2 Acquisition and Divestiture Activity for additional information. Total business segment financial results differ from total consolidated net income. These differences are reflected in the “Other” category in Table 82. “Other” includes residual activities that do not meet the criteria for disclosure as a separate reportable business, such as asset and liability management activities including net securities gains or losses, ACL for investment securities, certain trading activities, certain runoff consumer loan portfolios, private equity investments, intercompany eliminations, certain corporate overhead, tax adjustments that are not allocated to business segments, exited businesses and differences between business segment performance reporting and financial statement reporting (GAAP). Assets, revenue and earnings attributable to foreign activities were not material in the periods presented for comparison. Financial results are presented, to the extent practicable, as if each business operated on a stand-alone basis. Additionally, we have aggregated the results for corporate support functions within “Other” for financial reporting purposes. Net interest income in business segment results reflects our internal funds transfer pricing methodology. Assets receive a funding charge and liabilities and capital receive a funding credit based on a transfer pricing methodology that incorporates product repricing characteristics, tenor and other factors. We have allocated the ALLL and the allowance for unfunded lending related commitments based on the loan exposures within each business segment’s portfolio. Key reserve assumptions and estimation processes react to and are influenced by observed changes in loan portfolio performance experience, the financial strength of the borrower and economic conditions. Key reserve assumptions are periodically updated.

(b) Out-of-scope noninterest income includes revenue streams that fall under the scope of other accounting and disclosure requirements outside of Topic 606. Asset Management Services and Brokerage Fees Asset Management Group provides both personal wealth and institutional asset management services including investment management, custody services, retirement planning, family planning, trust management and retirement plan fiduciary investment services. As a result of the acquisition of BBVA, the Asset Management Group assumed brokerage account client assets, resulting in brokerage fee revenue, included in the table above for the three and nine months ended September 30, 2021. We recognize fee revenue over the term of the customer contract based on the value of assets under management at a point in time.

Accounting Policies [Abstract]
Business and Basis of Financial Statement Presentation	B USINESS PNC is one of the largest diversified financial services companies in the U.S. and is headquartered in Pittsburgh, Pennsylvania. Basis of Financial Statement Presentation Our consolidated financial statements include the accounts of the parent company and its subsidiaries, most of which are wholly-owned, certain partnership interests and VIEs. On June 1, 2021, we acquired BBVA, a U.S. financial holding company conducting its business operations primarily through its U.S. banking subsidiary, BBVA USA. Our results for the first nine months of 2021 reflect BBVA's acquired business operations for the period since the acquisition closed on June 1, 2021. Our balance sheet at September 30, 2021 includes BBVA's balances. See Note 2 Acquisition and Divestiture Activity for additional information on this acquisition. We prepared these consolidated financial statements in accordance with GAAP. We have eliminated intercompany accounts and transactions. We have also reclassified certain prior year amounts to conform to the current period presentation, which did not have a material impact on our consolidated financial condition or results of operations. In our opinion, the unaudited interim consolidated financial statements reflect all normal, recurring adjustments needed to present fairly our results for the interim periods. The results of operations for interim periods are not necessarily indicative of the results that may be expected for the full year or any other interim period. We have also considered the impact of subsequent events on these consolidated financial statements. When preparing these unaudited interim consolidated financial statements, we have assumed that you have read the audited consolidated financial statements included in our 2020 Form 10-K. Reference is made to Note 1 Accounting Policies in our 2020 Form 10-K for a detailed description of significant accounting policies. These interim consolidated financial statements serve to update our 2020 Form 10-K and may not include all information and Notes necessary to constitute a complete set of financial statements. There have been no significant changes to our accounting policies as disclosed in our 2020 Form 10-K.
Use of Estimates	Use of Estimates We prepared these consolidated financial statements using financial information available at the time of preparation, which requires us to make estimates and assumptions that affect the amounts reported. Our most significant estimates pertain to the ACL and our fair value measurements, including for the BBVA acquisition. Actual results may differ from the estimates and the differences may be material to the consolidated financial statements.

PNC will no longer allocate the consolidated amount of current and deferred income tax expense to certain qualifying stand-alone entities, which will impact the presentation of parent company tax expense subsequent to adoption. Accounting Standards Update Description Financial Statement Impact Reference Rate Reform - ASU 2020-04 Issued March 2020 Reference Rate Reform Scope - ASU 2021-01 Issued January 2021 • Provides optional expedients and exceptions for applying generally accepted accounting principles to contracts, hedging relationships and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform (codified in ASC 848). • Includes optional expedients related to contract modifications that allow an entity to account for modifications (if certain criteria are met) as if the modifications were only minor (assets within the scope of ASC 310, Receivables ), were not substantial (assets within the scope of ASC 470, Debt ) and/or did not result in remeasurements or reclassifications (assets within the scope of ASC 842, Leases , and other Topics) of the existing contract. • Includes optional expedients related to hedging relationships within the scope of ASC 815, Derivatives & Hedging , whereby changes to the critical terms of a hedging relationship do not require dedesignation if certain criteria are met. In addition, potential sources of ineffectiveness as a result of reference rate reform may be disregarded when performing some effectiveness assessments. • Includes optional expedients and exceptions for contract modifications and hedge accounting that apply to derivative instruments impacted by the market-wide discounting transition. • Allows for a one-time election to sell, transfer, or both sell and transfer debt securities classified as held to maturity that reference a rate affected by reference rate reform and that are classified as held to maturity before January 1, 2020. • Guidance in these ASUs are effective as of March 12, 2020 through December 31, 2022. • ASU 2020-04 was adopted March 12, 2020.

These optional expedients remove the requirement to remeasure contract modifications or dedesignate hedging relationships due to reference rate reform. • As of September 30, 2021, we have not yet elected to apply any optional expedients for contract modifications and hedging relationships to any other financial instruments. However, we plan to elect these optional expedients in the future. Accounting Standards Update Description Financial Statement Impact SEC Paragraph Amendments – ASU 2020-09 Issued October 2020 • Amends the financial disclosure requirements for guarantors and issuers of guaranteed securities registered or being registered, and issuers’ affiliates whose securities collateralize securities registered or being registered in Regulation S-X. • Improves disclosure requirements for both investors and registrants. • Provides investors with material information given the specific facts and circumstances, making the disclosures easier to understand and reducing the costs and burdens to registrants. • Adopted January 4, 2021. • In accordance with the requirements of this ASU, we included Exhibit 22 in the Exhibit Index of Item 6 of this Report to disclose PNC’s guarantee of the PNC Capital Trust C preferred securities.
