Accounting Policies [Abstract]
Accounting Policies	B USINESS The PNC Financial Services Group, Inc. (PNC) is one of the largest diversified financial services companies in the United States (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 variable interest entities. We prepared these consolidated financial statements in accordance with accounting principles generally accepted in the United States of America (GAAP). We have eliminated intercompany accounts and transactions. 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 2019 Form 10-K. These interim consolidated financial statements serve to update our 2019 Form 10-K and may not include all information and Notes necessary to constitute a complete set of financial statements. There have been significant changes to our accounting policies as disclosed in our 2019 Form 10-K due to the adoption of the Current Expected Credit Losses (CECL) standard and our discontinued operation as a result of the disposal of our equity investment in BlackRock. As a result of this disposal, BlackRock’s historical results of operations are reported as discontinued operations in our consolidated financial statements for all periods presented. The updated policies impacted by these changes are included in this Note 1. Reference is made to Note 1 Accounting Policies in our 2019 Form 10-K for a detailed description of all other significant accounting policies. 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 our fair value measurements and allowance for credit losses (ACL). Actual results may differ from the estimates and the differences may be material to the consolidated financial statements. Discontinued Operations A disposal of an asset or business that meets the criteria for held for sale classification is reported as discontinued operations when the disposal represents a strategic shift that has had, or will have, a major effect on our operating results. We report an asset as held for sale when management has approved or received approval to sell the asset and is committed to a formal plan, the asset is available for immediate sale, the asset is being actively marketed, the sale is anticipated to occur during the ensuing year and certain other specified criteria are met. An asset classified as held for sale is recorded at the lower of its carrying amount or estimated fair value less cost to sell. If the carrying amount of the asset exceeds its estimated fair value, the asset is written down to its fair value upon the held for sale designation. Our BlackRock held for sale asset is recorded at its carrying amount as we accounted for this investment under the equity method of accounting and the fair value of the asset exceeded the carrying value at each balance sheet date. When presenting discontinued operations, assets classified as held for sale are segregated in the Consolidated Balance Sheet commencing in the period in which the asset meets all of the held for sale criteria described above and prior periods are recast. The results of discontinued operations are reported in Discontinued Operations in the Consolidated Statement of Income for current and prior periods commencing in the period in which the asset or business is either disposed of or is classified as held for sale, including any gain or loss recognized on the sale or adjustment of the carrying amount to fair value less cost to sell. Earnings Per Common Share Basic earnings per common share is calculated using the two-class method to determine income attributable to common shareholders. Unvested share-based payment awards that contain nonforfeitable rights to dividends or dividend equivalents are considered participating securities under the two-class method. Distributed dividends and dividend equivalents related to participating securities and an allocation of undistributed net income to participating securities reduce the amount of income attributable to common shareholders. In a period with a loss, no allocation will be made to the participating securities, as they do not have a contractual obligation to absorb losses. Income attributable to common shareholders is then divided by the weighted-average common shares outstanding for the period. Diluted earnings per common share is calculated under the more dilutive of either the treasury method or the two-class method. For the diluted calculation, we increase the weighted-average number of shares of common stock outstanding by the assumed conversion of outstanding convertible preferred stock from the beginning of the year or date of issuance, if later, and the number of shares of common stock that would be issued assuming the exercise of stock options and warrants and the issuance of incentive shares using the treasury stock method. These adjustments to the weighted-average number of shares of common stock outstanding are made only when such adjustments will dilute earnings per common share. For periods in which there is a loss from continuing operations, any potential dilutive shares will be anti-dilutive. In this scenario, no potential dilutive shares will be included in the continuing operations, discontinued operations or total earnings per common share calculations, even if overall net income is reported. See Note 11 Earnings Per Share for additional information. Recently Adopted Accounting Standards Accounting Standards Update (ASU) Description Financial Statement Impact Credit Losses- ASU 2016-13 Issued June 2016 Codification Improvements - ASU 2019-04 Various improvements related to Credit Losses (Topics 1, 2 and 5) Issued April 2019 Targeted Transition Relief - Credit Losses - ASU 2019-05 Issued May 2019 Codification Improvements - ASU 2019-11 Issued November 2019 • Commonly referred to as the CECL standard. • Replaces measurement, recognition and disclosure guidance for credit related reserves ( i.e. , the allowance for loan and lease losses (ALLL) and the allowance for unfunded loan commitments and letters of credit) and Other than Temporary Impairment (OTTI) for debt securities. • Requires the use of an expected credit loss methodology; specifically, current expected credit losses for the remaining life of the asset will be recognized starting from the time of origination or acquisition. • Methodology applies to loans, net investment in leases, debt securities and certain financial assets not accounted for at fair value through net income. It also applies to unfunded lending related commitments except for unconditionally cancellable commitments. • In-scope assets are presented at the net amount expected to be collected after the deduction or addition of the ACL from the amortized cost basis of the assets. • Requires inclusion of expected recoveries of previously charged-off amounts for in-scope assets. • Requires enhanced credit quality disclosures including disaggregation of credit quality indicators by vintage. • Requires a modified retrospective approach through a cumulative-effect adjustment to retained earnings at adoption. • Adopted January 1, 2020 under the modified retrospective approach. The cumulative-effect adjustment to retained earnings totaled $671 million at adoption. • Amended presentation and disclosures are required prospectively. Refer to the disclosures in this Note 1, Note 3 Investment Securities, Note 4 Loans and Related Allowance for Credit Losses and Note 10 Total Equity and Other Comprehensive Income for additional information. • With the adoption of CECL, we discontinued the accounting for purchased impaired loans and elected the one-time fair value option election for some of these loans and certain residential real estate collateral dependent loans. Loans that were previously accounted for as purchased impaired where the fair value option election was not made are now accounted for as purchased credit deteriorated (PCD) loans. • There was no impact to the recorded investment of our investment securities or loans, except for our PCD loan portfolio. Accounting for these loans as PCD required an adjustment to the remaining accretable discount and recorded investment in addition to the impact on ACL due to the adoption of CECL methodology. • Refer to Table 35 for a summary of the impact of the CECL standard adoption. Accounting Standards Update (ASU) Description Financial Statement Impact Codification Improvements - ASU 2019-04 Topic 3: Codification Improvements to ASU 2017-12 and Other Hedging Items Issued April 2019 • Targeted improvements related to: - Partial-term fair value hedges of interest rate risk - Amortization of fair value hedge basis adjustments - Disclosure of fair value hedge basis adjustments - Consideration of the hedged contractually specified interest rate under the hypothetical derivative method - Application of a first-payments-received cash flow hedging technique to overall cash flows on a group of variable interest payments - Update to transition guidance for ASU 2017-12 • This ASU permits a one-time transfer out of held to maturity securities to provide entities the opportunity to hedge fixed rate, prepayable securities under a last of layer hedging strategy (although an entity is not required to hedge such securities subsequent to transfer). • Adopted January 1, 2020. • As permitted by the eligibility requirements in this guidance, at adoption we elected to transfer debt securities with an amortized cost of $16.2 billion (fair value of $16.5 billion) from held to maturity to the available for sale portfolio. The transfer resulted in a pretax increase to AOCI of $306 million. There were no other impacts to PNC's consolidated financial statements from the adoption of this guidance. Accounting Standards Update (ASU) Description Financial Statement Impact Goodwill - ASU 2017-04 Issued January 2017 • Eliminates Step 2 from the goodwill impairment test to simplify the subsequent measurement of goodwill under which a loss was recognized only if the estimated implied fair value of the goodwill is below its carrying value. • Requires impairment to be recognized if the reporting unit's carrying value exceeds the fair value. • Adopted January 1, 2020. • The adoption of this standard did not impact our consolidated results of operations or our consolidated financial position. Accounting Standards Update (ASU) Description Financial Statement Impact Reference Rate Reform - ASU 2020-04 Issued March 2020 • 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. • 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. • 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 this ASU is effective as of March 12, 2020 through December 31, 2022. • Adopted March 12, 2020, will apply prospectively. • As of September 30, 2020, we have not yet elected any optional expedients related to contract modifications or hedging relationships as outlined in this ASU. However, we plan to elect these optional expedients in the future. • During the second quarter of 2020, we elected to transfer all debt securities classified as held to maturity that are indexed to LIBOR to the available for sale portfolio. All securities were classified as held to maturity prior to January 1, 2020. These securities had an amortized cost and fair value of $49 million and $48 million, respectively, as of the transfer date. See Note 3 Investment Securities for more information.

Cash, Cash Equivalents and Restricted Cash Cash and due from banks are considered cash and cash equivalents for financial reporting purposes because they represent a primary source of liquidity. Certain cash balances within Cash and due from banks on our Consolidated Balance Sheet are restricted as to withdrawal or usage by legally binding contractual agreements or regulatory requirements. Investments We hold interests in various types of investments. The accounting for these investments is dependent on a number of factors including, but not limited to, items such as: • Ownership interest, • Our plans for the investment, and • The nature of the investment. Debt Securities Debt securities are recorded on a trade-date basis. We classify debt securities as either trading, held to maturity, or available for sale. Debt securities that we purchase for certain risk management activities or customer-related trading activities are classified as trading securities, are reported in the Other assets line item on our Consolidated Balance Sheet, and are carried at fair value. Realized and unrealized gains and losses on trading securities are included in Other noninterest income. We classify debt securities as held to maturity when we have the positive intent and ability to hold the securities to maturity, and carry them at amortized cost, less any allowance. Debt securities not classified as held to maturity or trading are classified as securities available for sale, and are carried at fair value. Unrealized gains and losses on available for sale securities are included in Accumulated other comprehensive income (AOCI) net of income taxes. We include all interest on debt securities, including amortization of premiums and accretion of discounts on investment securities, in net interest income using the constant effective yield method generally calculated over the contractual lives of the securities. Effective yields reflect either the effective interest rate implicit in the security at the date of acquisition or, for debt securities where an other-than-temporary impairment was recorded, the effective interest rate determined based on improved cash flows subsequent to an impairment. We compute gains and losses realized on the sale of available for sale debt securities on a specific security basis. These securities gains/(losses) are included in Other noninterest income on the Consolidated Income Statement. As discussed in the Recently Adopted Accounting Standards section of this Note 1 , we adopted the CECL standard as of January 1, 2020, which requires expected credit losses on both held to maturity and available for sale securities to be recognized through a valuation allowance, ACL, instead of as a direct write-down to the amortized cost basis of the security. An available for sale security is considered impaired if the fair value is less than amortized cost basis. If any portion of the decline in fair value is related to credit, the amount of allowance is determined as the portion related to credit, limited to the difference between the amortized cost basis and the fair value of the security. If we have the intent to sell or believe it is more likely than not we will be required to sell an impaired available for sale security before recovery of the amortized cost basis, the credit loss is recorded as a direct write-down of the amortized cost basis. Credit losses on investment securities are recognized through the Provision for credit losses on our Consolidated Income Statement. Declines in the fair value of available for sale securities that are not considered credit related are recognized in AOCI on our Consolidated Balance Sheet. The CECL standard is applied prospectively to debt securities and, as a result, the amortized cost basis of investment securities for which OTTI had previously been recorded did not change upon adoption. For information on the policies previously applied to determine OTTI, see the Debt Securities section of Note 1 Accounting Policies in our 2019 Form 10-K. We consider a security to be past due in terms of payment based on its contractual terms. A security may be placed on nonaccrual, with interest no longer recognized until received, when collectability of principal or interest is doubtful. As of September 30, 2020 , nonaccrual or past due held-to-maturity securities were immaterial. A security may be partially or fully charged off against the allowance if it is determined to be uncollectible, including, for an available for sale security, if we have the intent to sell or believe it is more likely than not we will be required to sell the security before recovery of the amortized cost basis. Recoveries of previously charged-off available for sale securities are recognized when received, while recoveries on held to maturity securities are recognized when expected. See the Allowance for Credit Loss section of this Note 1 for further discussion regarding the methodologies used to determine the allowance for investment securities. See Note 3 Investment Securities for additional information about the investment securities portfolio and the related ACL. Loans Loans are classified as held for investment when management has both the intent and ability to hold the loan for the foreseeable future, or until maturity or payoff. Management’s intent and view of the foreseeable future may change based on changes in business strategies, the economic environment, market conditions and the availability of government programs. 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. See Note 4 Loans and Related Allowance for Credit Losses for additional information on how COVID-19 hardship related loan modifications are reported from a delinquency perspective as of September 30, 2020. Loans held for investment, excluding PCD loans, are recorded at amortized cost basis unless we elect to measure these under the fair value option. Amortized cost basis represents principal amounts outstanding, net of unearned income, unamortized deferred fees, costs on originated loans, and premiums or discounts on purchased loans, and charge-offs. Amortized cost basis does not include accrued interest, as we include accrued interest in Other assets on our Consolidated Balance Sheet. Interest on performing loans is accrued based on the principal amount outstanding and recorded in Interest income as earned using the constant effective yield method. Loan origination fees, direct loan origination costs, and loan premiums and discounts are deferred and accreted or amortized into Net interest income using the constant effective yield method, over the contractual life of the loan. The processing fee received for loans originated under the Paycheck Protection Program (PPP) is deferred and accreted into Net interest income using the effective yield method, over the contractual life of the loan. Loans under the fair value option are reported at their fair value, with any changes to fair value reported as Noninterest income on the Consolidated Income Statement, and are excluded from measurement of ALLL. In addition to originating loans, we also acquire loans through the secondary loan market, portfolio purchases or acquisitions of other financial services companies. Certain acquired loans that have experienced a more than significant deterioration of credit quality since origination (i.e., PCD) are recognized at an amortized cost basis equal to their purchase price plus an ALLL measured at the acquisition date. Subsequent decreases in expected cash flows that are attributable, at least in part, to credit quality are recognized through a charge to the provision for credit losses resulting in an increase in the ALLL. Subsequent increases in expected cash flows are recognized as a provision recapture of previously recorded ALLL. We consider a loan to be collateral dependent when we determine that substantially all of the expected cash flows will be generated from the operation or sale of the collateral underlying the loan, the borrower is experiencing financial difficulty and we have elected to measure the loan at the estimated fair value of collateral (less costs to sell if sale or foreclosure of the property is expected). Additionally, we consider a loan to be collateral dependent when foreclosure or liquidation of the underlying collateral is probable. A troubled debt restructuring (TDR) is a loan whose terms have been restructured in a manner that grants a concession to a borrower experiencing financial difficulty. A concession has been granted when we do not expect to collect all amounts due, including original interest accrued at the original contract rate, as a result of the restructuring, or there is a delay in payment that is more than insignificant. TDRs result from our loss mitigation activities, and include rate reductions, principal forgiveness, postponement/reduction of scheduled amortization, and extensions, which are intended to minimize economic loss and to avoid foreclosure or repossession of collateral. Additionally, TDRs also result from borrowers that have been discharged from personal liability through Chapter 7 bankruptcy and have not formally reaffirmed their loan obligations to us. In those situations where principal is forgiven, the amount of such principal forgiveness is immediately charged off. Potential incremental losses or recoveries on TDRs have been factored into the ALLL estimates for each loan class under the methodologies described in this Note. Once a loan becomes a TDR, it will continue to be reported as a TDR until it is ultimately repaid in full, the collateral is foreclosed upon, or it is fully charged off. PNC excludes consumer loans held for sale, loans accounted for under the fair value option and certain government insured or guaranteed loans from our TDR population. PCD loans that do not meet the criteria to be classified as TDRs are also excluded. In addition, PNC has elected not to apply a TDR designation to loans that have been restructured due to a COVID-19 hardship pursuant to specific criteria under the CARES Act. Since loans restructured due to a COVID-19 related hardship were not identified as TDRs, they are not placed on nonaccrual at the time of modification. However, these loans will be subject to our existing nonaccrual policy subsequent to the modification. See the following for additional information related to loans, including further discussion regarding our policies, the methodologies and significant inputs used to determine the ALLL, and additional details on the composition of our loan portfolio: • Nonperforming Loans and Leases section of this Note 1, • Allowance for Credit Losses section of this Note 1 , and • Note 4 Loans and Related Allowance for Credit Losses. Loans Held for Sale We designate loans as held for sale when we have the intent to sell them. At the time of designation to held for sale, any allowance is reversed, and a valuation allowance for the shortfall between the amortized cost basis and the net realizable value is recognized, excluding the amounts already charged off. Similarly, when loans are no longer considered held for sale, the valuation allowance (net of writedowns) is reversed, and an allowance for credit losses is established, excluding the amounts already charged-off. Write-downs on these loans (if required) are recorded as charge-offs through the valuation allowance. Adjustments to the valuation allowance on held for sale loans are recognized in Other noninterest income. We have elected to account for certain commercial and residential mortgage loans held for sale at fair value. The changes in the fair value of the commercial mortgage loans are measured and recorded in Other noninterest income while such changes for the residential mortgage loans are measured and recorded in Residential mortgage noninterest income each period. See Note 12 Fair Value for additional information. Interest income with respect to loans held for sale is accrued based on the principal amount outstanding and the loan’s contractual interest rate. In certain circumstances, loans designated as held for sale may be transferred to held for investment based on a change in strategy. We transfer these loans at the lower of cost or estimated fair value; however, any loans originated or purchased as held for sale for which the fair value option has been elected remain at fair value for the life of the loan. Nonperforming Loans and Leases The matrix that follows summarizes our policies for classifying certain loans as nonperforming loans and/or discontinuing the accrual of loan interest income. Commercial Loans Classified as Nonperforming and Accounted for as Nonaccrual • Loans accounted for at amortized cost where: – The loan is 90 days or more past due. – The loan is rated substandard or worse due to the determination that full collection of principal and interest is not probable as demonstrated by the following conditions: • The collection of principal or interest is 90 days or more past due; • Reasonable doubt exists as to the certainty of the borrower’s future debt service ability, according to the terms of the credit arrangement, regardless of whether 90 days have passed or not; • The borrower has filed or will likely file for bankruptcy; • The bank advances additional funds to cover principal or interest; • We are in the process of liquidating a commercial borrower; or • We are pursuing remedies under a guarantee. Loans Excluded from Nonperforming Classification but Accounted for as Nonaccrual • Loans accounted for under the fair value option and full collection of principal and interest is not probable. • Loans accounted for at the lower of cost or market less costs to sell (held for sale) and full collection of principal and interest is not probable. Loans Excluded from Nonperforming Classification and Nonaccrual Accounting • Loans that are well secured and in the process of collection. • Certain government insured loans where substantially all principal and interest is insured. • Commercial purchasing card assets which do not accrue interest. Consumer Loans Classified as Nonperforming and Accounted for as Nonaccrual • Loans accounted for at amortized cost where full collection of contractual principal and interest is not deemed probable as demonstrated in the policies below: – The loan is 90 days past due for home equity and installment loans, and 180 days past due for well secured residential real estate loans; – The loan has been modified and classified as a troubled debt restructuring (TDR); – Notification of bankruptcy has been received; – The bank holds a subordinate lien position in the loan and the first lien mortgage loan is seriously stressed (i.e., 90 days or more past due); – Other loans within the same borrower relationship have been placed on nonaccrual or charge-offs have been taken on them; – The bank has ordered the repossession of non-real estate collateral securing the loan; or – The bank has charged-off the loan to the value of the collateral. Loans Excluded from Nonperforming Classification but Accounted for as Nonaccrual • Loans accounted for under the fair value option and full collection of principal and interest is not probable. • Loans accounted for at the lower of cost or market less costs to sell (held for sale) and full collection of principal and interest is not probable. Loans Excluded from Nonperforming Classification and Nonaccrual Accounting • Certain government insured loans where substantially all principal and interest is insured. • Residential real estate loans that are well secured and in the process of collection. • Consumer loans and lines of credit, not secured by residential real estate or automobiles, as permitted by regulatory guidance. Commercial We generally charge off commercial (commercial and industrial, commercial real estate, and equipment lease financing) nonperforming loans when we determine that a specific loan, or portion thereof, is uncollectible. This determination is based on the specific facts and circumstances of the individual loans. In making this determination, we consider the viability of the business or project as a going concern, the past due status when the asset is not well-secured, the expected cash flows to repay the loan, the value of the collateral, and the ability and willingness of any guarantors to perform. Additionally, in general, for smaller commercial loans of $1 million or less, a partial or full charge-off occurs at 120 days past due for term loans and 180 days past due for revolvers. Certain small business credit card balances that are placed on nonaccrual status when they become 90 days or more past due are charged-off at 180 days past due. Consumer We generally charge off secured consumer (home equity, residential real estate and automobile) nonperforming loans to the fair value of collateral less costs to sell, if lower than the amortized cost basis of the loan outstanding, when delinquency of the loan, combined with other risk factors (e.g., bankruptcy, lien position, or troubled debt restructuring), indicates that the loan, or some portion thereof, is uncollectible as per our historical experience, or the collateral has been repossessed. We charge-off secured consumer loans no later than 180 days past due. Most consumer loans and lines of credit, not secured by automobiles or residential real estate, are charged off once they have reached 120-180 days past due. For secured collateral dependent loans, collateral values are updated at least annually and subsequent declines in collateral values are charged-off resulting in incremental provision for credit loss. Subsequent increases in collateral values may be reflected as an adjustment to the ALLL to reflect the expectation of recoveries in an amount greater than previously expected. Accounting for Nonperforming Assets and Leases and Other Nonaccrual Loans For nonaccrual loans, interest income accrual and deferred fee/cost recognition is discontinued. Additionally, the current year accrued and uncollected interest is reversed through Net interest income and prior year accrued and uncollected interest is charged-off, except for credit cards, where we reverse any accrued interest th

Investment Securities Disclosure [Abstract]
Investment Securities	I NVESTMENT S ECURITIES With the adoption of the CECL standard on January 1, 2020, credit losses on investment securities are required to be recognized through an allowance, instead of as a direct write-down to the amortized cost basis of the security. The amortized cost basis of investment securities for which impairment had previously been recorded did not change upon adoption. We maintain the allowance for investment securities at levels that we believe to be appropriate as of the balance sheet date to absorb expected credit losses on our portfolio. As of September 30, 2020 , the allowance for investment securities was $71 million and primarily related to non-agency commercial mortgage-backed securities in the available for sale portfolio and other debt securities in the held to maturity portfolio. The provision for credit losses on investment securities totaled $39 million and $69 million for the three and nine months ended September 30, 2020 . In the first quarter of 2020, upon the adoption of ASU 2019-04, we elected to transfer debt securities with an amortized cost of $16.2 billion and a fair value of $16.5 billion from the held to maturity to the available for sale portfolio. During the second quarter of 2020, pursuant to the guidance in ASU 2020-04, we elected to transfer debt securities with an amortized cost of $49 million and a fair value of $48 million from the held to maturity to the available for sale portfolio. See Note 1 Accounting Policies for additional information related to the adoption of the CECL standard, including the methodologies used to determine the allowance for investment securities, and the adoption of ASU 2019-04 and ASU 2020-04. The following table summarizes our available for sale and held to maturity portfolios by major security type.

These amounts are included in Other assets on the Consolidated Balance Sheet. (b) Amortized cost is presented net of allowance of $ 68 million for securities available for sale and $ 3 million for securities held to maturity at September 30, 2020 in accordance with the adoption of the CECL accounting standard. See the Recently Adopted Accounting Standards portion of Note 1 Accounting Policies for additional detail on the adoption of this ASU. (c) Credit ratings represent a primary credit quality indicator used to monitor and manage credit risk. As of September 30, 2020 , 85% of our securities held to maturity were rated AAA/AA. 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, 2020 included $.7 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, 2019 was $.3 billion . Table 39 presents the gross unrealized losses and fair value of securities available for sale that do not have an associated allowance for investment securities as of September 30, 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, 2020 , 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	Loans and Related Allowance for Credit Losses 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 • Home equity • Commercial real estate • Residential real estate • Equipment lease financing • Automobile • Credit card • Education • Other consumer See Note 1 Accounting Policies 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. With the adoption of the CECL standard, accruing loans past due as of September 30, 2020 include PCD loans, while amounts as of December 31, 2019 excluded purchased impaired loans. See Note 1 Accounting Policies for additional information related to the adoption of this standard, including the discontinuation of purchased impaired loan accounting. The following table presents the composition and delinquency status of our loan portfolio at September 30, 2020 and December 31, 2019 . Pursuant to the interagency guidance issued in April 2020 and in connection with the credit reporting rules from the CARES Act, the September 30, 2020 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. As a result, certain loans modified due to COVID-19 related hardships are not being reported as past due as of September 30, 2020 based on the contractual terms of the loan, even where borrowers may not be making payments on their loans during the modification period. Loan modifications due to COVID-19 related hardships that permanently reduce either the contractual interest rate or the principal balance of a loan do not qualify for TDR relief under the CARES Act or the interagency guidance.

Recorded investment does not include any associated valuation allowance. (h) Past due loan amounts exclude purchased impaired loans, even if contractually past due (or if we do not expect to receive payment in full based on the original contractual terms), as we accreted interest income over the expected life of the loans. Past due loan amounts include government insured or guaranteed Residential real estate loans totaling $.4 billion and Education loans totaling $.2 billion at December 31, 2019. (i) 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. (j) Net of unearned income, unamortized deferred fees and costs on originated loans, and premiums or discounts on purchased loans totaling $1.1 billion at December 31, 2019. At September 30, 2020 , we pledged $ 30.5 billion of commercial loans to the Federal Reserve Bank and $ 68.9 billion of residential real estate and other loans to the Federal Home Loan Bank as collateral for the ability to borrow, if necessary. The comparable amounts at December 31, 2019 were $16.9 billion and $68.0 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. 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 substantially all principal and interest are not reported as nonperforming loans and continue to accrue interest. With the adoption of the CECL standard, nonperforming loans as of September 30, 2020 include PCD loans. Amounts as of December 31, 2019 excluded purchased impaired loans as we were accreting interest income over the expected life of the loans. See Note 1 Accounting Policies for additional information related to the adoption of this standard and our nonperforming loan and lease policies. The following table presents our nonperforming assets as of September 30, 2020 and December 31, 2019, respectively.

(b) Nonperforming loans for which there is no related ALLL totaled $.6 billion at September 30, 2020 , and is primarily comprised of loans with a valuation that exceeds the amortized cost basis. Nonperforming loans also 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 and the TDR section of this Note 4 for additional information on TDRs. Total nonperforming loans in Table 45 include TDRs of $.8 billion and $.9 billion at September 30, 2020 and December 31, 2019 , respectively. TDRs that are performing, including consumer credit card TDR loans, totaled $.8 billion at both September 30, 2020 and December 31, 2019 and are excluded from nonperforming loans. Additional Credit Quality Indicators by Loan Class Commercial and Industrial For commercial and industrial loans, we monitor the performance of the borrower in a disciplined and regular manner based upon the level of credit risk inherent in the loan. To evaluate the level of credit risk, we assign an internal risk rating reflecting the borrower’s PD and LGD. This two-dimensional credit risk rating methodology provides granularity in the risk monitoring process. These ratings are reviewed and updated, generally at least once per year. For small balance homogeneous pools of commercial and industrial loans and leases, we apply scoring techniques to assist in determining the PD. The combination of the PD and LGD ratings assigned to commercial and industrial loans, capturing both the combination of expectations of default and loss severity in the event of default, reflects credit quality characteristics as of the reporting date and are used as inputs into our loss forecasting process. Based upon the amount of the lending arrangement and our risk rating assessment, we follow a formal schedule of written periodic reviews. Quarterly, we conduct formal reviews of a market’s or business unit’s loan portfolio, focusing on those loans which we perceive to be of higher risk, based upon PDs and LGDs, or loans for which credit quality is weakening. If circumstances warrant, it is our practice to review any customer obligation and its level of credit risk more frequently. We attempt to proactively manage our loans by using various procedures that are customized to the risk of a given loan, including ongoing outreach, contact, and assessment of obligor financial conditions, collateral inspection and appraisal. Commercial Real Estate We manage credit risk associated with our commercial real estate projects and commercial mortgages similar to commercial and industrial loans by evaluating PD and LGD. Risks associated with commercial real estate projects and commercial mortgage activities tend to be correlated to the loan structure and collateral location, project progress and business environment. As a result, these attributes are also monitored and utilized in assessing credit risk. As with the commercial and industrial loan class, a formal schedule of periodic reviews is also performed to assess market/geographic risk and business unit/industry risk. Often as a result of these overviews, more in-depth reviews and increased scrutiny are placed on areas of higher risk, such as adverse changes in risk ratings, deteriorating operating trends, and/or areas that concern management. These reviews are designed to assess risk and facilitate actions to mitigate such risks. Equipment Lease Financing We manage credit risk associated with our equipment lease financing loan class similar to commercial and industrial loans by analyzing PD and LGD. Based upon the dollar amount of the lease and the level of credit risk, we follow a formal schedule of periodic reviews. Generally, this occurs quarterly, although we have established practices to review such credit risk more frequently if circumstances warrant. Our review process entails analysis of the following factors: equipment value/residual value, exposure levels, jurisdiction risk, industry risk, guarantor requirements, and regulatory compliance as applicable.

The Criticized classification includes loans that were rated special mention, substandard or doubtful as of September 30, 2020 and December 31, 2019. Home Equity and Residential Real Estate We use several credit quality indicators, including delinquency information, nonperforming loan information, updated credit scores, originated and updated LTV ratios, to monitor and manage credit risk within the home equity and residential real estate loan classes. A summary of credit quality indicators follows: Delinquency/Delinquency Rates : We monitor trending of delinquency/delinquency rates for home equity and residential real estate loans. See Table 44 for additional information. Nonperforming Loans : We monitor trending of nonperforming loans for home equity and residential real estate loans. See Table 44 for additional information. Credit Scores: We use a national third-party provider to update FICO credit scores for home equity and residential real estate loans at least quarterly. The updated scores are incorporated into a series of credit management reports, which are utilized to monitor the risk in the loan classes. LTV (inclusive of combined loan-to-value (CLTV) for first and subordinate lien positions): At least annually, we update the property values of real estate collateral and calculate an updated LTV ratio. For open-end credit lines secured by real estate in regions experiencing significant declines in property values, more frequent valuations may occur. We examine LTV migration and stratify LTV into categories to monitor the risk in the loan classes. We use a combination of original LTV and updated LTV for internal risk management and reporting purposes ( e.g. , line management, loss mitigation strategies). In addition to the fact that estimated property values by their nature are estimates, given certain data limitations, it is important to note that updated LTVs may be based upon management’s assumptions ( i.e. , if an updated LTV is not provided by the third-party service provider, HPI changes will be incorporated in arriving at management’s estimate of updated LTV). Updated LTV is estimated using modeled property values. The related estimates and inputs are based upon an approach that uses a combination of third-party automated valuation models, broker price opinions, HPI indices, property location, internal and external balance information, origination data and management assumptions. We generally utilize origination lien balances provided by a third-party, where applicable, which do not include an amortization assumption when calculating updated LTV. Accordingly, the results of the calculations do not represent actual appraised loan level collateral or updated LTV based upon lien balances held by others, and as such, are necessarily imprecise and subject to change as we refine our methodology. The following table presents credit quality indicators for the home equity and residential real estate loan classes.

For all loan types, we generally use a combination of internal loan parameters as well as an updated FICO score. We use FICO scores as a primary credit quality indicator for automobile and credit card loans, as well as non-government guaranteed or non-insured education loans and other secured and unsecured lines and loans. Internal credit metrics, such as delinquency status, are heavily relied upon as credit quality indicators for government guaranteed or insured education loans and consumer loans to high net worth individuals, as internal credit metrics are more relevant than FICO scores for these types of loans. Along with the monitoring of delinquency trends and losses for each class, FICO credit score updates are obtained at least quarterly along with a variety of credit bureau attributes. Loans with high FICO scores tend to have a lower likelihood of loss. Conversely, loans with low FICO scores tend to have a higher likelihood of loss. The following table presents credit quality indicators for the automobile, credit card, education and other consumer loan classes.

Management proactively assesses the risk and size of this loan category and, when necessary, takes actions to mitigate the credit risk. (b) Weighted-average updated FICO score excludes accounts with no FICO score available or required. Troubled Debt Restructurings (TDRs) A TDR is a loan whose terms have been restructured in a manner that grants a concession to a borrower experiencing financial difficulty. Loans that have been restructured for COVID-19 related hardships and meet certain criteria under the CARES Act are not categorized as TDRs. See Note 1 Accounting Policies for additional information related to TDRs. Table 49 quantifies the number of loans that were classified as TDRs as well as the change in the loans’ balance as a result of becoming a TDR during the three and nine months ended September 30, 2020 and September 30, 2019 . Additionally, the table provides information about the types of TDR concessions. See Note 3 Asset Quality in our 2019 Form 10-K for additional details on these TDR concessions.

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. The following table provides a summary of TDRs that subsequently defaulted during the periods presented and were classified as TDRs during the applicable 12-month period preceding September 30, 2020 and September 30, 2019 .

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 2 Loan Sale and Servicing Activities and Variable Interest Entities in our 2019 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 special purpose entities (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 9 Commitments and Note 12 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 54 : Cash Flows Associated with Loan Sale and Servicing Activities In millions Residential Commercial 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 - Three months ended September 30, 2019 Sales of loans (b) $ 1,296 $ 1,122 Repurchases of previously transferred loans (c) $ 81 Servicing fees (d) $ 90 $ 34 Servicing advances recovered/(funded), net $ 5 $ 45 Cash flows on mortgage-backed securities held (e) $ 1,394 $ 14 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 Cash Flows - Nine months ended September 30, 2019 Sales of loans (b) $ 2,902 $ 2,212 Repurchases of previously transferred loans (c) $ 235 $ 4 Servicing fees (d) $ 264 $ 97 Servicing advances recovered/(funded), net $ 33 $ 61 Cash flows on mortgage-backed securities held (e) $ 2,653 $ 43 (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 removal of account provision 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 $19.5 billion, $ 17.8 billion, and $ 17.7 billion in residential mortgage-backed securities and $.8 billion, $ .6 billion, and $ .6 billion in commercial mortgage-backed securities at September 30, 2020 , December 31, 2019 and September 30, 2019 , respectively. Table 55 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, 2020 .

(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 2 Loan Sale and Servicing Activities and Variable Interest Entities in our 2019 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 56 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 56 . 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 limited liability companies (LLCs). The purpose of these investments is to achieve a satisfactory return on capital and to assist us in achieving goals associated with the Community Reinvestment Act. Within Income taxes, during the nine months ended September 30, 2020 , we recognized $ 140 million of amortization, $ 144 million of tax credits and $ 32 million of other tax benefits associated with qualified investments in low income housing tax credits. The amounts for the third quarter of 2020 were $ 44 million, $ 46 million and $ 10

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Mortgage Servicing Rights	G OODWILL AND M ORTGAGE S ERVICING R IGHTS Goodwill See Note 1 Accounting Policies in this Report and Note 7 Goodwill and Mortgage Servicing Rights in our 2019 Form 10-K for more information regarding our goodwill. 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 adequate compensation. MSRs totaled $ 1.1 billion and $ 1.6 billion at September 30, 2020 and December 31, 2019 , 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, as well as Note 6 Fair Value in our 2019 Form 10-K for more detail on our fair value measurement of MSRs. Refer to Note 7 Goodwill and Mortgage Servicing Rights in our 2019 Form 10-K for more information on our accounting and measurement of MSRs. Changes in the commercial and residential MSRs follow: Table 57 : Mortgage Servicing Rights Commercial MSRs Residential MSRs In millions 2020 2019 2020 2019 January 1 $ 649 $ 726 $ 995 $ 1,257 Additions: From loans sold with servicing retained 65 29 34 23 Purchases 31 76 113 87 Changes in fair value due to: Time and payoffs (a) (87 ) (110 ) (136 ) (117 ) Other (b) (143 ) (126 ) (408 ) (362 ) September 30 $ 515 $ 595 $ 598 $ 888 Related unpaid principal balance at September 30 $ 234,897 $ 203,808 $ 119,158 $ 122,886 Servicing advances at September 30 $ 363 $ 159 $ 107 $ 123 (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, 2020 are shown in Tables 58 and 59 . 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 58 and 59 . 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.

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) Represents aggregate maximum exposure up to the specified limits of the reinsurance contracts provided by our wholly-owned captive insurance subsidiary. These amounts reflect estimates based on availability of financial information from insurance carriers. As of September 30, 2020 , the aggregate maximum exposure amount was zero for accidental death and dismemberment contracts, and $.1 billion for credit life, accident and health contracts. Comparable amounts at December 31, 2019 were $ 1.3 billion and $.1 billion , respectively. (c) We enter into standby bond purchase agreements to support municipal bond obligations. (d) Includes $.6 billion related to investments in qualified affordable housing projects for both September 30, 2020 and December 31, 2019 . 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 96% of our net outstanding standby letters of credit were rated as Pass as of September 30, 2020 , 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, 2020 had terms ranging from less than one year to six years. As of September 30, 2020 , assets of $1.1 billion secured certain specifically identified standby letters of credit. In addition, a portion of the remaining standby letters of credit issued on behalf of specific customers is also secured by collateral or guarantees that secure the customers’ other obligations to us. The carrying amount of the liability for our obligations related to standby letters of credit and participations in standby letters of credit was $.2 billion at September 30, 2020 and is included in Other liabilities on our Consolidated Balance Sheet.

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 6 Fair Value in our 2019 Form 10-K. 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 6 Fair Value in our 2019 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.

(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.

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 risk 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 (commonly LIBOR), 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 13 Financial Derivatives in our 2019 Form 10-K. The following table presents the notional amounts and gross fair values of all derivative assets and liabilities held by us.

(e) Includes both residential and commercial mortgage banking activities. (f) Futures contracts settle in cash daily and, therefore, no derivative asset or derivative liability is 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 13 . 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 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 interest rate swaps and forward contracts 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, 2020 , we expect to reclassify net derivative gains of $402 million pretax, or $310 million after-tax, from AOCI to interest income for both 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, 2020 . As of September 30, 2020 , 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.

(c) Includes an insignificant amount of fair value hedge adjustments related to discontinued hedge relationships. (d) Detail regarding the impact of fair value hedge accounting on the carrying value of the hedged items is presented in the following table. Table 78 : Hedged Items - Fair Value Hedges September 30, 2020 December 31, 2019 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) $ 3,237 $ 59 $ 5,666 $ 59 Borrowed funds $ 28,326 $ 1,850 $ 28,616 $ 548 (a) Includes $(.2) billion and $(.3) billion of fair value hedge adjustments primarily related to discontinued borrowed funds hedge relationships for September 30, 2020 and December 31, 2019 , 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. Gains (losses) on net investment hedge derivatives recognized in OCI were $(42) million and $38 million for the three and nine months ended September 30, 2020 , respectively, compared with $36 million and $50 million for the same periods in 2019. Derivatives Not Designated As Hedging Instruments For additional information on derivatives not designated as hedging instruments under GAAP, see Note 13 Financial Derivatives in our 2019 Form 10-K. Further detail regarding the gains (losses) on derivatives not designated in hedging relationships is presented in the following table.

(b) Includes an insignificant amount of gains (losses) on commodity contracts for all periods presented. (c) 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 13 Financial Derivatives in our 2019 Form 10-K. Table 80 shows the impact legally enforceable master netting agreements had on our derivative assets and derivative liabilities as of September 30, 2020 and December 31, 2019 . 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, 2020 , we held cash, U.S. government securities and mortgage-backed securities totaling $2.6 billion under master netting agreements and other collateral agreements to collateralize net derivative assets due from counterparties, and we pledged cash totaling $2.1 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. Certain derivative agreements contain various credit-risk related contingent provisions, such as those that require our debt to maintain a specified credit rating from one or more of the major credit rating agencies. If our debt ratings were to fall below such specified ratings, the counterparties to the derivative instruments could request immediate payment or demand immediate and ongoing full collateralization on derivative instruments in net liability positions. The aggregate fair value of all derivative instruments with credit-risk-related contingent features that were in a net liability position on September 30, 2020 was $2.9 billion for which we had posted collateral of $2.6 billion in the normal course of business. The maximum additional amount of collateral we would have been required to post if the credit-risk-related contingent features underlying these agreements had been triggered on September 30, 2020 would be $.3 billion .

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 14 as well as those matters disclosed in Note 19 Legal Proceedings in Part II, Item 8 of our 2019 Form 10-K, in Note 13 Legal Proceedings in Part I, Item 1 of our first quarter 2020 Form 10-Q, and in Note 14 Legal Proceedings in Part I, Item 1 of our second quarter 2020 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, 2020 , 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 19 in our 2019 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. USAA Patent Infringement Litigation In September 2020, a lawsuit (United Services Automobile Association v. PNC Bank N.A., Case No. 2:20-cv-319) was filed in the United States District Court for the Eastern District of Texas against PNC Bank for patent infringement. The plaintiff alleges that PNC’s mobile remote deposit capture systems infringe on two patents owned by the plaintiff. The plaintiff seeks, among other things, a judgment that PNC is infringing each of the patents, damages for infringement, and attorneys’ fees. 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 reviews of specified activities at multiple industry participants; in others, they are directed at PNC individually. From time to time, these inquiries, including those described in Prior Disclosure, may involve or lead to regulatory enforcement actions and other administrative proceedings, and may 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 financially 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. During the second quarter of 2020, we divested our entire 22.4% investment in BlackRock. See Note 2 Discontinued Operations for additional information on the sale and details on our results and cash flows for the three and nine months ended September 30, 2020 and 2019. Following the sale and donation, PNC only holds shares of BlackRock stock in a fiduciary capacity for clients of PNC. Total business segment financial results differ from total consolidated net income. These differences are reflected in the “Other” category in Table 81 . “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), including the presentation of net income attributable to noncontrolling interests as the segments’ results exclude their portion of net income attributable to noncontrolling interests. The “Other” category also includes our BlackRock held for sale asset. Assets, revenue and earnings attributable to foreign activities were not material in the period 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.

Accounting Policies [Abstract]
Basis of Financial Statement Presentation	B USINESS The PNC Financial Services Group, Inc. (PNC) is one of the largest diversified financial services companies in the United States (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 variable interest entities. We prepared these consolidated financial statements in accordance with accounting principles generally accepted in the United States of America (GAAP). We have eliminated intercompany accounts and transactions. 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 2019 Form 10-K. These interim consolidated financial statements serve to update our 2019 Form 10-K and may not include all information and Notes necessary to constitute a complete set of financial statements. There have been significant changes to our accounting policies as disclosed in our 2019 Form 10-K due to the adoption of the Current Expected Credit Losses (CECL) standard and our discontinued operation as a result of the disposal of our equity investment in BlackRock. As a result of this disposal, BlackRock’s historical results of operations are reported as discontinued operations in our consolidated financial statements for all periods presented. The updated policies impacted by these changes are included in this Note 1. Reference is made to Note 1 Accounting Policies in our 2019 Form 10-K for a detailed description of all other significant accounting policies.
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 our fair value measurements and allowance for credit losses (ACL). Actual results may differ from the estimates and the differences may be material to the consolidated financial statements.
Discontinued Operations	Discontinued Operations A disposal of an asset or business that meets the criteria for held for sale classification is reported as discontinued operations when the disposal represents a strategic shift that has had, or will have, a major effect on our operating results. We report an asset as held for sale when management has approved or received approval to sell the asset and is committed to a formal plan, the asset is available for immediate sale, the asset is being actively marketed, the sale is anticipated to occur during the ensuing year and certain other specified criteria are met. An asset classified as held for sale is recorded at the lower of its carrying amount or estimated fair value less cost to sell. If the carrying amount of the asset exceeds its estimated fair value, the asset is written down to its fair value upon the held for sale designation. Our BlackRock held for sale asset is recorded at its carrying amount as we accounted for this investment under the equity method of accounting and the fair value of the asset exceeded the carrying value at each balance sheet date. When presenting discontinued operations, assets classified as held for sale are segregated in the Consolidated Balance Sheet commencing in the period in which the asset meets all of the held for sale criteria described above and prior periods are recast. The results of discontinued operations are reported in Discontinued Operations in the Consolidated Statement of Income for current and prior periods commencing in the period in which the asset or business is either disposed of or is classified as held for sale, including any gain or loss recognized on the sale or adjustment of the carrying amount to fair value less cost to sell.
Earnings Per Common Share	Earnings Per Common Share Basic earnings per common share is calculated using the two-class method to determine income attributable to common shareholders. Unvested share-based payment awards that contain nonforfeitable rights to dividends or dividend equivalents are considered participating securities under the two-class method. Distributed dividends and dividend equivalents related to participating securities and an allocation of undistributed net income to participating securities reduce the amount of income attributable to common shareholders. In a period with a loss, no allocation will be made to the participating securities, as they do not have a contractual obligation to absorb losses. Income attributable to common shareholders is then divided by the weighted-average common shares outstanding for the period.
Recently Adopted Accounting Standards	Recently Adopted Accounting Standards Accounting Standards Update (ASU) Description Financial Statement Impact Credit Losses- ASU 2016-13 Issued June 2016 Codification Improvements - ASU 2019-04 Various improvements related to Credit Losses (Topics 1, 2 and 5) Issued April 2019 Targeted Transition Relief - Credit Losses - ASU 2019-05 Issued May 2019 Codification Improvements - ASU 2019-11 Issued November 2019 • Commonly referred to as the CECL standard. • Replaces measurement, recognition and disclosure guidance for credit related reserves ( i.e. , the allowance for loan and lease losses (ALLL) and the allowance for unfunded loan commitments and letters of credit) and Other than Temporary Impairment (OTTI) for debt securities. • Requires the use of an expected credit loss methodology; specifically, current expected credit losses for the remaining life of the asset will be recognized starting from the time of origination or acquisition. • Methodology applies to loans, net investment in leases, debt securities and certain financial assets not accounted for at fair value through net income. It also applies to unfunded lending related commitments except for unconditionally cancellable commitments. • In-scope assets are presented at the net amount expected to be collected after the deduction or addition of the ACL from the amortized cost basis of the assets. • Requires inclusion of expected recoveries of previously charged-off amounts for in-scope assets. • Requires enhanced credit quality disclosures including disaggregation of credit quality indicators by vintage. • Requires a modified retrospective approach through a cumulative-effect adjustment to retained earnings at adoption. • Adopted January 1, 2020 under the modified retrospective approach. The cumulative-effect adjustment to retained earnings totaled $671 million at adoption. • Amended presentation and disclosures are required prospectively. Refer to the disclosures in this Note 1, Note 3 Investment Securities, Note 4 Loans and Related Allowance for Credit Losses and Note 10 Total Equity and Other Comprehensive Income for additional information. • With the adoption of CECL, we discontinued the accounting for purchased impaired loans and elected the one-time fair value option election for some of these loans and certain residential real estate collateral dependent loans. Loans that were previously accounted for as purchased impaired where the fair value option election was not made are now accounted for as purchased credit deteriorated (PCD) loans. • There was no impact to the recorded investment of our investment securities or loans, except for our PCD loan portfolio. Accounting for these loans as PCD required an adjustment to the remaining accretable discount and recorded investment in addition to the impact on ACL due to the adoption of CECL methodology. • Refer to Table 35 for a summary of the impact of the CECL standard adoption. Accounting Standards Update (ASU) Description Financial Statement Impact Codification Improvements - ASU 2019-04 Topic 3: Codification Improvements to ASU 2017-12 and Other Hedging Items Issued April 2019 • Targeted improvements related to: - Partial-term fair value hedges of interest rate risk - Amortization of fair value hedge basis adjustments - Disclosure of fair value hedge basis adjustments - Consideration of the hedged contractually specified interest rate under the hypothetical derivative method - Application of a first-payments-received cash flow hedging technique to overall cash flows on a group of variable interest payments - Update to transition guidance for ASU 2017-12 • This ASU permits a one-time transfer out of held to maturity securities to provide entities the opportunity to hedge fixed rate, prepayable securities under a last of layer hedging strategy (although an entity is not required to hedge such securities subsequent to transfer). • Adopted January 1, 2020. • As permitted by the eligibility requirements in this guidance, at adoption we elected to transfer debt securities with an amortized cost of $16.2 billion (fair value of $16.5 billion) from held to maturity to the available for sale portfolio. The transfer resulted in a pretax increase to AOCI of $306 million. There were no other impacts to PNC's consolidated financial statements from the adoption of this guidance. Accounting Standards Update (ASU) Description Financial Statement Impact Goodwill - ASU 2017-04 Issued January 2017 • Eliminates Step 2 from the goodwill impairment test to simplify the subsequent measurement of goodwill under which a loss was recognized only if the estimated implied fair value of the goodwill is below its carrying value. • Requires impairment to be recognized if the reporting unit's carrying value exceeds the fair value. • Adopted January 1, 2020. • The adoption of this standard did not impact our consolidated results of operations or our consolidated financial position. Accounting Standards Update (ASU) Description Financial Statement Impact Reference Rate Reform - ASU 2020-04 Issued March 2020 • 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. • 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. • 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 this ASU is effective as of March 12, 2020 through December 31, 2022. • Adopted March 12, 2020, will apply prospectively. • As of September 30, 2020, we have not yet elected any optional expedients related to contract modifications or hedging relationships as outlined in this ASU. However, we plan to elect these optional expedients in the future. • During the second quarter of 2020, we elected to transfer all debt securities classified as held to maturity that are indexed to LIBOR to the available for sale portfolio. All securities were classified as held to maturity prior to January 1, 2020. These securities had an amortized cost and fair value of $49 million and $48 million, respectively, as of the transfer date. See Note 3 Investment Securities for more information. The following table presents the impact of adopting the CECL standard on January 1, 2020 on our allowance and retained earnings. Table 35 : Impact of the CECL Standard Adoption In millions December 31, 2019 Transition Adjustment January 1, 2020 Allowance for credit losses Allowance for loan and lease losses Commercial $ 1,812 $ (304 ) $ 1,508 Consumer 930 767 1,697 Total allowance for loan and lease losses 2,742 463 3,205 Unfunded lending related commitments 318 179 497 Other — 19 19 Total allowance for credit losses $ 3,060 $ 661 $ 3,721 In millions December 31, 2019 Transition Adjustment January 1, 2020 Impact to retained earnings (a) $ 42,215 $ (671 ) $ 41,544 (a) Transition adjustment includes the increase in the total ACL of $.7 billion and the impact of the fair value option election of $.2 billion , offset by the tax impact of $.2 billion . Cash, Cash Equivalents and Restricted Cash Cash and due from banks are considered cash and cash equivalents for financial reporting purposes because they represent a primary source of liquidity. Certain cash balances within Cash and due from banks on our Consolidated Balance Sheet are restricted as to withdrawal or usage by legally binding contractual agreements or regulatory requirements. Investments We hold interests in various types of investments. The accounting for these investments is dependent on a number of factors including, but not limited to, items such as: • Ownership interest, • Our plans for the investment, and • The nature of the investment. Debt Securities Debt securities are recorded on a trade-date basis. We classify debt securities as either trading, held to maturity, or available for sale. Debt securities that we purchase for certain risk management activities or customer-related trading activities are classified as trading securities, are reported in the Other assets line item on our Consolidated Balance Sheet, and are carried at fair value. Realized and unrealized gains and losses on trading securities are included in Other noninterest income. We classify debt securities as held to maturity when we have the positive intent and ability to hold the securities to maturity, and carry them at amortized cost, less any allowance. Debt securities not classified as held to maturity or trading are classified as securities available for sale, and are carried at fair value. Unrealized gains and losses on available for sale securities are included in Accumulated other comprehensive income (AOCI) net of income taxes. We include all interest on debt securities, including amortization of premiums and accretion of discounts on investment securities, in net interest income using the constant effective yield method generally calculated over the contractual lives of the securities. Effective yields reflect either the effective interest rate implicit in the security at the date of acquisition or, for debt securities where an other-than-temporary impairment was recorded, the effective interest rate determined based on improved cash flows subsequent to an impairment. We compute gains and losses realized on the sale of available for sale debt securities on a specific security basis. These securities gains/(losses) are included in Other noninterest income on the Consolidated Income Statement. As discussed in the Recently Adopted Accounting Standards section of this Note 1 , we adopted the CECL standard as of January 1, 2020, which requires expected credit losses on both held to maturity and available for sale securities to be recognized through a valuation allowance, ACL, instead of as a direct write-down to the amortized cost basis of the security. An available for sale security is considered impaired if the fair value is less than amortized cost basis. If any portion of the decline in fair value is related to credit, the amount of allowance is determined as the portion related to credit, limited to the difference between the amortized cost basis and the fair value of the security. If we have the intent to sell or believe it is more likely than not we will be required to sell an impaired available for sale security before recovery of the amortized cost basis, the credit loss is recorded as a direct write-down of the amortized cost basis. Credit losses on investment securities are recognized through the Provision for credit losses on our Consolidated Income Statement. Declines in the fair value of available for sale securities that are not considered credit related are recognized in AOCI on our Consolidated Balance Sheet. The CECL standard is applied prospectively to debt securities and, as a result, the amortized cost basis of investment securities for which OTTI had previously been recorded did not change upon adoption. For information on the policies previously applied to determine OTTI, see the Debt Securities section of Note 1 Accounting Policies in our 2019 Form 10-K. We consider a security to be past due in terms of payment based on its contractual terms. A security may be placed on nonaccrual, with interest no longer recognized until received, when collectability of principal or interest is doubtful. As of September 30, 2020 , nonaccrual or past due held-to-maturity securities were immaterial. A security may be partially or fully charged off against the allowance if it is determined to be uncollectible, including, for an available for sale security, if we have the intent to sell or believe it is more likely than not we will be required to sell the security before recovery of the amortized cost basis. Recoveries of previously charged-off available for sale securities are recognized when received, while recoveries on held to maturity securities are recognized when expected. See the Allowance for Credit Loss section of this Note 1 for further discussion regarding the methodologies used to determine the allowance for investment securities. See Note 3 Investment Securities for additional information about the investment securities portfolio and the related ACL. Loans Loans are classified as held for investment when management has both the intent and ability to hold the loan for the foreseeable future, or until maturity or payoff. Management’s intent and view of the foreseeable future may change based on changes in business strategies, the economic environment, market conditions and the availability of government programs. 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. See Note 4 Loans and Related Allowance for Credit Losses for additional information on how COVID-19 hardship related loan modifications are reported from a delinquency perspective as of September 30, 2020. Loans held for investment, excluding PCD loans, are recorded at amortized cost basis unless we elect to measure these under the fair value option. Amortized cost basis represents principal amounts outstanding, net of unearned income, unamortized deferred fees, costs on originated loans, and premiums or discounts on purchased loans, and charge-offs. Amortized cost basis does not include accrued interest, as we include accrued interest in Other assets on our Consolidated Balance Sheet. Interest on performing loans is accrued based on the principal amount outstanding and recorded in Interest income as earned using the constant effective yield method. Loan origination fees, direct loan origination costs, and loan premiums and discounts are deferred and accreted or amortized into Net interest income using the constant effective yield method, over the contractual life of the loan. The processing fee received for loans originated under the Paycheck Protection Program (PPP) is deferred and accreted into Net interest income using the effective yield method, over the contractual life of the loan. Loans under the fair value option are reported at their fair value, with any changes to fair value reported as Noninterest income on the Consolidated Income Statement, and are excluded from measurement of ALLL. In addition to originating loans, we also acquire loans through the secondary loan market, portfolio purchases or acquisitions of other financial services companies. Certain acquired loans that have experienced a more than significant deterioration of credit quality since origination (i.e., PCD) are recognized at an amortized cost basis equal to their purchase price plus an ALLL measured at the acquisition date. Subsequent decreases in expected cash flows that are attributable, at least in part, to credit quality are recognized through a charge to the provision for credit losses resulting in an increase in the ALLL. Subsequent increases in expected cash flows are recognized as a provision recapture of previously recorded ALLL. We consider a loan to be collateral dependent when we determine that substantially all of the expected cash flows will be generated from the operation or sale of the collateral underlying the loan, the borrower is experiencing financial difficulty and we have elected to measure the loan at the estimated fair value of collateral (less costs to sell if sale or foreclosure of the property is expected). Additionally, we consider a loan to be collateral dependent when foreclosure or liquidation of the underlying collateral is probable. A troubled debt restructuring (TDR) is a loan whose terms have been restructured in a manner that grants a concession to a borrower experiencing financial difficulty. A concession has been granted when we do not expect to collect all amounts due, including original interest accrued at the original contract rate, as a result of the restructuring, or there is a delay in payment that is more than insignificant. TDRs result from our loss mitigation activities, and include rate reductions, principal forgiveness, postponement/reduction of scheduled amortization, and extensions, which are intended to minimize economic loss and to avoid foreclosure or repossession of collateral. Additionally, TDRs also result from borrowers that have been discharged from personal liability through Chapter 7 bankruptcy and have not formally reaffirmed their loan obligations to us. In those situations where principal is forgiven, the amount of such principal forgiveness is immediately charged off. Potential incremental losses or recoveries on TDRs have been factored into the ALLL estimates for each loan class under the methodologies described in this Note. Once a loan becomes a TDR, it will continue to be reported as a TDR until it is ultimately repaid in full, the collateral is foreclosed upon, or it is fully charged off. PNC excludes consumer loans held for sale, loans accounted for under the fair value option and certain government insured or guaranteed loans from our TDR population. PCD loans that do not meet the criteria to be classified as TDRs are also excluded. In addition, PNC has elected not to apply a TDR designation to loans that have been restructured due to a COVID-19 hardship pursuant to specific criteria under the CARES Act. Since loans restructured due to a COVID-19 related hardship were not identified as TDRs, they are not placed on nonaccrual at the time of modification. However, these loans will be subject to our existing nonaccrual policy subsequent to the modification. See the following for additional information related to loans, including further discussion regarding our policies, the methodologies and significant inputs used to determine the ALLL, and additional details on the composition of our loan portfolio: • Nonperforming Loans and Leases section of this Note 1, • Allowance for Credit Losses section of this Note 1 , and • Note 4 Loans and Related Allowance for Credit Losses. Loans Held for Sale We designate loans as held for sale when we have the intent to sell them. At the time of designation to held for sale, any allowance is reversed, and a valuation allowance for the shortfall between the amortized cost basis and the net realizable value is recognized, excluding the amounts already charged off. Similarly, when loans are no longer considered held for sale, the valuation allowance (net of writedowns) is reversed, and an allowance for credit losses is established, excluding the amounts already charged-off. Write-downs on these loans (if required) are recorded as charge-offs through the valuation allowance. Adjustments to the valuation allowance on held for sale loans are recognized in Other noninterest income. We have elected to account for certain commercial and residential mortgage loans held for sale at fair value. The changes in the fair value of the commercial mortgage loans are measured and recorded in Other noninterest income while such changes for the residential mortgage loans are measured and recorded in Residential mortgage noninterest income each period. See Note 12 Fair Value for additional information. Interest income with respect to loans held for sale is accrued based on the principal amount outstanding and the loan’s contractual interest rate. In certain circumstances, loans designated as held for sale may be transferred to held for investment based on a change in strategy. We transfer these loans at the lower of cost or estimated fair value; however, any loans originated or purchased as held for sale for which the fair value option has been elected remain at fair value for the life of the loan. Nonperforming Loans and Leases The matrix that follows summarizes our policies for classifying certain loans as nonperforming loans and/or discontinuing the accrual of loan interest income. Commercial Loans Classified as Nonperforming and Accounted for as Nonaccrual • Loans accounted for at amortized cost where: – The loan is 90 days or more past due. – The loan is rated substandard or worse due to the determination that full collection of principal and interest is not probable as demonstrated by the following conditions: • The collection of principal or interest is 90 days or more past due; • Reasonable doubt exists as to the certainty of the borrower’s future debt service ability, according to the terms of the credit arrangement, regardless of whether 90 days have passed or not; • The borrower has filed or will likely file for bankruptcy; • The bank advances additional funds to cover principal or interest; • We are in the process of liquidating a commercial borrower; or • We are pursuing remedies under a guarantee. Loans Excluded from Nonperforming Classification but Accounted for as Nonaccrual • Loans accounted for under the fair value option and full collection of principal and interest is not probable. • Loans accounted for at the lower of cost or market less costs to sell (held for sale) and full collection of principal and interest is not probable. Loans Excluded from Nonperforming Classification and Nonaccrual Accounting • Loans that are well secured and in the process of collection. • Certain government insured loans where substantially all principal and interest is insured. • Commercial purchasing card assets which do not accrue interest. Consumer Loans Classified as Nonperforming and Accounted for as Nonaccrual • Loans accounted for at amortized cost where full collection of contractual principal and interest is not deemed probable as demonstrated in the policies below: – The loan is 90 days past due for home equity and installment loans, and 180 days past due for well secured residential real estate loans; – The loan has been modified and classified as a troubled debt restructuring (TDR); – Notification of bankruptcy has been received; – The bank holds a subordinate lien position in the loan and the first lien mortgage loan is seriously stressed (i.e., 90 days or more past due); – Other loans within the same borrower relationship have been placed on nonaccrual or charge-offs have been taken on them; – The bank has ordered the repossession of non-real estate collateral securing the loan; or – The bank has charged-off the loan to the value of the collateral. Loans Excluded from Nonperforming Classification but Accounted for as Nonaccrual • Loans accounted for under the fair value option and full collection of principal and interest is not probable. • Loans accounted for at the lower of cost or market less costs to sell (held for sale) and full collection of principal and interest is not probable. Loans Excluded from Nonperforming Classification and Nonaccrual Accounting • Certain government insured loans where substantially all principal and interest is insured. • Residential real estate loans that are well secured and in the process of collection. • Consumer loans and lines of credit, not secured by residential real estate or automobiles, as permitted by regulatory guidance. Commercial We generally charge off commercial (commercial and industrial, commercial real estate, and equipment lease financing) nonperforming loans when we determine that a specific loan, or portion thereof, is uncollectible. This determination is based on the specific facts and circumstances of the individual loans. In making this determination, we consider the viability of the business or project as a going concern, the past due status when the asset is not well-secured, the expected cash flows to repay the loan, the value of the collateral, and the ability and willingness of any guarantors to perform. Additionally, in general, for smaller commercial loans of $1 million or less, a partial or full charge-off occurs at 120 days past due for term loans and 180 days past due for revolvers. Certain small business credit card balances that are placed on nonaccrual status when they become 90 days or more past due are charged-off at 180 days past due. Consumer We generally charge off secured consumer (home equity, residential real estate and automobile) nonperforming loans to the fair value of collateral less costs to sell, if lower than the amortized cost basis of the loan outstanding, when delinquency of the loan, combined with other risk factors (e.g., bankruptcy, lien position, or troubled debt restructuring), indicates that the loan, or some portion thereof, is uncollectible as per our historical experience, or the collateral has been repossessed. We charge-off secured consumer loans no later than 180 days past due. Most consumer loans and lines of credit, not secured by automobiles or residential real estate, are charged off once they have reached 120-180 days past due. For secured collateral dependent loans, collateral values are updated at least annually and subsequent declines in collateral values are charged-off resulting in incremental provision for credit loss. Subsequent increases in collateral values may be reflected as an adjustment to the ALLL to reflect the expectation of recoveries in an amount greater than previously expected. Accounting for Nonperforming Assets and Leases and Other Nonaccrual Loans For nonaccrual loans, interest income accrual and deferred fee/cost recognition is discontinued. Additionally, the current year accrued and uncollected interest is reversed through Net interest income and prior year accrued and uncollected interest is charged-off, except for credit cards, where we reverse any accrued interest through Net interest income at the time of charge-off, as per industry standard practice. Nonaccrual loans that are also collateral dependent may be charged-off to reduce the basis to the fair value of collateral less costs to sell. If payment is received on a nonaccrual loan, generally the payment is first applied to the remaining principal balance; payments are then applied to recover any charged-off amounts related to the loan. Finally, if both principal balance and any charge-offs have been recovered, then the payment will be recorded as fee and interest income. For certain consumer loans, the receipt of interest payments is recognized as interest income on a cash basis. Cash basis income recognition is applied if a loan’s amortized cost basis is deemed fully collectible and the loan has performed for at least six months. For TDRs, payments are applied based upon their contractual terms unless the related loan is deemed non-performing. TDRs are generally included in nonperforming and nonaccrual loans. However, after a reasonable period of time, generally six months, in which the loan performs under restructured terms and meets other performance indicators, it is returned to performing/accruing status. This return to performing/accruing status demonstrates that the bank expects to collect all of the loan’s remaining contractual principal and interest. TDRs resulting from (i) borrowers that have been discharged from personal liability through Chapter 7 bankruptcy and have not formally reaffirmed their loan obligations to us, and (ii) borrowers that are not currently obligated to make both principal and interest payments under the restructured terms are not returned to accrual status. Other nonaccrual loans are generally not returned to accrual status until the borrower has performed in accordance with the contractual terms and other performance indicators for at least six months, the period of time which was determined to demonstrate the expected collection of the loan’s remaining contractual principal and interest. Nonaccrual loans with partially charged-off principal are not returned to accrual. When a nonperforming loan is returned to accrual status, it is then considered a performing loan. Foreclosed assets consist of any asset seized or property acquired through a foreclosure proceeding or acceptance of a deed-in-lieu of foreclosure. Other real estate owned (OREO) comprises principally commercial and residential real estate properties obtained in partial or total satisfaction of loan obligations. After obtaining a foreclosure judgment, or in some jurisdictions the initiation of proceedings under a power of sale in the loan instruments, the property will be sold. When we are awarded title or completion of deed-in-lieu of foreclosure, we transfer the loan to foreclosed assets included in Other assets on our Consolidated Balance Sheet. Property obtained in satisfaction of a loan is initially recorded at estimated fair value less cost to sell. Based upon the estimated fair value less cost to sell, the amortized cost basis of the loan is adjusted and a charge-off/recovery is recognized to the ALLL. We estimate fair values primarily based on appraisals, or sales agreements with third parties. Subsequently, foreclosed assets are valued at the lower of the amount recorded at acquisition date or estimated fair value less cost to sell. Valuation adjustments on these assets and gains or losses realized from disposition of such property are reflected in Other noninterest expense. For certain mortgage loans that have a government guarantee, we establish a separate other receivable upon foreclosure. The receivable is measured based on the loan balance (inclusive of principal and interest) that is expected to be recovered from the guarantor. See Note 4 Loans and Related Allowance for Credit Losses in this Report for additional information on nonperforming assets, TDRs and credit quality indicators related to our loan portfolio. Allowance for Credit Losses Our ACL, in accordance with the CECL standard, is based on historical loss experience, borrower risk characteristics, current economic conditions, reasonable and supportable forecasts of future conditions and other relevant factors. We maintain the ACL at an appropriate level for expected losses on our existing investment securities, loans, finance leases (including residual values), other financial assets and unfunded lending related commitments, for the estimated contractual term of the assets or exposures as of the balance sheet date. We estimate the estimated contractual term of assets in scope of CECL considering contractual maturity dates, prepayment expectations, utilization or draw expectations and any embedded extension options that do not allow us to unilaterally cancel the extension options. For products without a fixed contractual maturity date ( e.g ., credit cards), we rely on historical payment behavior to determine the length of the pay down or default time period. We estimate expected losses on a pooled basis using a combination of (i) the expected losses over a reasonable and supportable forecast period (RSFP), (ii) a period of reversion to long run average (LRA) expected losses (reversion period) where applicable, and (iii) the LRA expected losses for the remaining estimated contractual term. For all assets and unfunded lending related commitments in the scope of CECL, the ACL also includes individually assessed reserves and qualitative reserves, as applicable. We use forward-looking information in estimating expected credit losses for the RSFP. For this purpose, we use the forecasted scenarios produced by PNC's Economics Team, which are designed to reflect business cycles and their related estimated probabilities. The forecast length that we have determined to be reasonable and supportable is three years. As noted in the methodology discussions that follow, forward looking information is incorporated into the expected credit loss estimates. Such forward looking information includes forecasted relevant macroeconomic variables, which are estimated using quantitative techniques, analysis from PNC economists and management judgment. The reversion period is used to bridge RSFP and LRA
Goodwill	Goodwill Goodwill arising from business acquisitions represents the value attributable to unidentifiable intangible elements in the business acquired. At least annually, in the fourth quarter, or more frequently if events occur or circumstances have changed significantly from the annual test date, management performs our goodwill impairment test at a reporting unit level. PNC has the ability to first perform a qualitative analysis to evaluate whether it is more-likely-than-not that the fair value of a reporting unit is less than its carrying amount. If, after considering all relevant events and circumstances, PNC determines it is not more-likely-than-not that the fair value of a reporting unit is less than its carrying amount, then performing a quantitative impairment test is not necessary. If PNC elects to bypass the qualitative analysis, or concludes via qualitative analysis that it is more-likely-than-not that the fair value of a reporting unit is less than its carrying amount, a quantitative goodwill impairment test is performed. Inputs are generated and used in calculating the fair value of the reporting unit, which is compared to its carrying amount. The fair value of our reporting units is determined by using discounted cash flows and/or market comparability methodologies. If the fair value is greater than the carrying amount, then the reporting unit's goodwill is deemed not to be impaired. If the fair value is less than the carrying amount, an entity should recognize an impairment charge for the amount by which the carrying amount of goodwill exceeds the reporting unit’s fair value. The loss recognized should not exceed the total amount of goodwill allocated to that reporting unit.

Accounting Policies [Abstract]
Recently Adopted Accounting Standards	Recently Adopted Accounting Standards Accounting Standards Update (ASU) Description Financial Statement Impact Credit Losses- ASU 2016-13 Issued June 2016 Codification Improvements - ASU 2019-04 Various improvements related to Credit Losses (Topics 1, 2 and 5) Issued April 2019 Targeted Transition Relief - Credit Losses - ASU 2019-05 Issued May 2019 Codification Improvements - ASU 2019-11 Issued November 2019 • Commonly referred to as the CECL standard. • Replaces measurement, recognition and disclosure guidance for credit related reserves ( i.e. , the allowance for loan and lease losses (ALLL) and the allowance for unfunded loan commitments and letters of credit) and Other than Temporary Impairment (OTTI) for debt securities. • Requires the use of an expected credit loss methodology; specifically, current expected credit losses for the remaining life of the asset will be recognized starting from the time of origination or acquisition. • Methodology applies to loans, net investment in leases, debt securities and certain financial assets not accounted for at fair value through net income. It also applies to unfunded lending related commitments except for unconditionally cancellable commitments. • In-scope assets are presented at the net amount expected to be collected after the deduction or addition of the ACL from the amortized cost basis of the assets. • Requires inclusion of expected recoveries of previously charged-off amounts for in-scope assets. • Requires enhanced credit quality disclosures including disaggregation of credit quality indicators by vintage. • Requires a modified retrospective approach through a cumulative-effect adjustment to retained earnings at adoption. • Adopted January 1, 2020 under the modified retrospective approach. The cumulative-effect adjustment to retained earnings totaled $671 million at adoption. • Amended presentation and disclosures are required prospectively. Refer to the disclosures in this Note 1, Note 3 Investment Securities, Note 4 Loans and Related Allowance for Credit Losses and Note 10 Total Equity and Other Comprehensive Income for additional information. • With the adoption of CECL, we discontinued the accounting for purchased impaired loans and elected the one-time fair value option election for some of these loans and certain residential real estate collateral dependent loans. Loans that were previously accounted for as purchased impaired where the fair value option election was not made are now accounted for as purchased credit deteriorated (PCD) loans. • There was no impact to the recorded investment of our investment securities or loans, except for our PCD loan portfolio. Accounting for these loans as PCD required an adjustment to the remaining accretable discount and recorded investment in addition to the impact on ACL due to the adoption of CECL methodology. • Refer to Table 35 for a summary of the impact of the CECL standard adoption. Accounting Standards Update (ASU) Description Financial Statement Impact Codification Improvements - ASU 2019-04 Topic 3: Codification Improvements to ASU 2017-12 and Other Hedging Items Issued April 2019 • Targeted improvements related to: - Partial-term fair value hedges of interest rate risk - Amortization of fair value hedge basis adjustments - Disclosure of fair value hedge basis adjustments - Consideration of the hedged contractually specified interest rate under the hypothetical derivative method - Application of a first-payments-received cash flow hedging technique to overall cash flows on a group of variable interest payments - Update to transition guidance for ASU 2017-12 • This ASU permits a one-time transfer out of held to maturity securities to provide entities the opportunity to hedge fixed rate, prepayable securities under a last of layer hedging strategy (although an entity is not required to hedge such securities subsequent to transfer). • Adopted January 1, 2020. • As permitted by the eligibility requirements in this guidance, at adoption we elected to transfer debt securities with an amortized cost of $16.2 billion (fair value of $16.5 billion) from held to maturity to the available for sale portfolio. The transfer resulted in a pretax increase to AOCI of $306 million. There were no other impacts to PNC's consolidated financial statements from the adoption of this guidance. Accounting Standards Update (ASU) Description Financial Statement Impact Goodwill - ASU 2017-04 Issued January 2017 • Eliminates Step 2 from the goodwill impairment test to simplify the subsequent measurement of goodwill under which a loss was recognized only if the estimated implied fair value of the goodwill is below its carrying value. • Requires impairment to be recognized if the reporting unit's carrying value exceeds the fair value. • Adopted January 1, 2020. • The adoption of this standard did not impact our consolidated results of operations or our consolidated financial position. Accounting Standards Update (ASU) Description Financial Statement Impact Reference Rate Reform - ASU 2020-04 Issued March 2020 • 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. • 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.
