Accounting Policies [Abstract]

Business and Basis of Financial Statement Presentation

BUSINESS

PNC is one of the largest diversified financial services companies in the U.S. and is headquartered in Pittsburgh, Pennsylvania.

We have businesses engaged in retail banking, including residential mortgage, corporate and institutional banking and asset management, providing many of our products and services nationally. Our retail branch network is located coast-to-coast. We also have strategic international offices in four countries outside the U.S.

Basis of Financial Statement Presentation

Our consolidated financial statements include the accounts of the parent company and its subsidiaries, most of which are wholly-owned, certain partnership interests and VIEs.

We prepared these consolidated financial statements in accordance with GAAP. We have eliminated intercompany accounts and transactions.

In our opinion, the unaudited interim consolidated financial statements reflect all normal, recurring adjustments needed to state 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 2022 Form 10-K. These interim consolidated financial statements serve to update our 2022 Form 10-K and may not include all information and Notes necessary to constitute a complete set of financial statements. There have been changes to certain of our accounting policies as disclosed in our 2022 Form 10-K due to the adoption of ASU 2022-02 Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures (ASU 2022-02) in the first quarter of 2023. The updated policies impacted by this adoption are included in this Note 1. Reference is made to Note 1 Accounting Policies in our 2022 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 the ACL and our fair value measurements. Actual results may differ from the estimates and the differences may be material to the consolidated financial statements.

Loans

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. Under the CARES Act credit reporting rules, certain loans modified due to pandemic related hardships are not being reported as past due based on the contractual terms of the loan, even where borrowers may not be making payments on their loans during the modification period. The CARES Act credit reporting rules expire in the third quarter of 2023.

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 and costs on originated loans, 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 over the contractual life. 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 through PPP lending under the CARES Act 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 the 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-insignificant 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. PNC considers a variety of factors in connection with the identification of more-than-insignificant deterioration in credit quality, including but not limited to nonperforming status, delinquency, risk ratings and other qualitative factors that indicate deterioration in credit quality since origination. 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, or when 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.

On January 1, 2023, we adopted ASU 2022-02, which eliminates the accounting guidance for TDRs. See Note 1 Accounting Policies in our 2022 Form 10-K for a description of our accounting policies for TDRs that were in effect prior to adoption.

Loan modifications to borrowers experiencing financial difficulty, or FDMs, result from our loss mitigation activities and include principal forgiveness, interest rate reductions, term extensions, payment delays, repayment plans or combinations thereof. FDMs continue to be subject to our existing nonaccrual policies. Expected losses or recoveries on FDMs have been factored into the ALLL estimates for each loan class under the methodologies described in this Note. Refer to Note 3 Loans and Related Allowance for Credit Losses for more information on FDMs.

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:

•Allowance for Credit Losses section of this Note 1,

•Note 4 Loans and Related Allowance for Credit Losses in our 2022 Form 10-K.

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, and it is not probable the borrower will be able to repay contractual payments due under the loan, •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 or guaranteed loans where substantially all principal and interest is insured. • Commercial purchasing card assets that 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 due to a borrower experiencing financial difficulty and is not government     insured or guaranteed, – The loan has been modified to defer prior payments in forbearance to the end of the loan term, –  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 or guaranteed 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. For commercial loans and leases less than a defined dollar threshold, balances are generally charged-off in full after 180 days for loans and 120 days for leases.

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 the fair value is lower than the amortized cost basis of the loan outstanding and the delinquency of the loan, combined with other risk factors such as bankruptcy or lien position, indicates that the loan (or a portion thereof) is uncollectible as per our historical experience. These nonperforming loans would also be charged-off when 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, limited to amounts previously charged-off.

Accounting for Nonperforming Assets and Leases and Other Nonaccrual Loans

For nonaccrual loans, interest income accrual and deferred fee/cost recognition is discontinued. Additionally, depending on whether the accrued interest has been incorporated into the ACL estimates, as discussed in the Accrued Interest section of this Note 1, the accrued and uncollected interest is either reversed through Net interest income (if a CECL reserve is not maintained for accrued interest) or charged-off against the allowance (if a CECL reserve is maintained for accrued interest), 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 loans modified due to a borrower experiencing financial difficulty, payments are applied based upon their contractual terms unless the related loan is deemed nonperforming. Loans modified due to a borrower experiencing financial difficulty are generally included in nonperforming and nonaccrual loans if they are not government insured or guaranteed. However, after a reasonable period of time, generally six months, in which the loan performs under modified 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. Loan modifications granted

to borrowers experiencing financial difficulty 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 modified 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. OREO comprises principally residential and commercial 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 3 Loans and Related Allowance for Credit Losses for additional information on FDMs, nonperforming assets and credit quality indicators related to our loan portfolio.

Allowance for Loan and Lease Losses

Allowance for Credit Losses

Our ACL is based on historical loss experience, current 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, equipment finance leases, other financial assets and unfunded lending related commitments, for the estimated contractual term of the assets or exposures as of the balance sheet date. The remaining contractual term of assets in scope of CECL is estimated considering contractual maturity dates, prepayment expectations, utilization or draw expectations and any contractually 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 paydown 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, (ii) a period of reversion to long-run average expected losses, where applicable and (iii) the long-run average 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 our reasonable and supportable forecast period. For this purpose, we use 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 currently 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 macroeconomic models, analysis from PNC economists and management judgment.

The reversion period is used to bridge our three-year reasonable and supportable forecast period and the long-run average expected credit losses. We consider a number of factors in determining the duration of the reversion period, such as contractual maturity of the asset, observed historical patterns and the estimated credit loss rates at the end of the forecast period relative to the beginning of the long-run average period. The reversion period is typically one to three years, if not immediate.

The long-run average expected credit losses are derived from long-run historical credit loss information adjusted for the credit quality of the current portfolio and, therefore, do not consider current and forecasted economic conditions.

See the following sections related to loans and unfunded lending related commitments for details about specific methodologies.

Allowance for Loan and Lease Losses

Our pooled expected loss methodology is based upon the quantification of risk parameters, such as PD, LGD and EAD for a loan, loan segment or lease. We also consider the impact of prepayments and amortization on contractual maturity in our expected loss estimates. We use historical credit loss information, current borrower risk characteristics and forecasted economic variables for the reasonable and supportable forecast period, coupled with analytical methods, to estimate these risk parameters by loan, loan segment or lease. PD, LGD and EAD parameters are calculated for each forecasted scenario and the long-run average period, and combined to generate expected loss estimates by scenario. The following matrix provides key credit risk characteristics that we use to estimate these risk parameters.

Loan Class	Probability of Default	Loss Given Default	Exposure at Default
Commercial
Commercial and industrial / Equipment lease financing	•For wholesale obligors: internal risk ratings based on borrower characteristics and industry •For retail small balance obligors: credit score, delinquency status, and product type	•Collateral type, LTV, industry, size and outstanding exposure for secured loans •Capital structure, industry and size for unsecured loans •For retail small balance obligors, product type and credit scores	•Outstanding balances, commitment, contractual maturities and historical prepayment experience for loans •Current utilization and historical pre-default draw experience for lines
Commercial real estate (CRE)	•Property performance metrics, property type, market and risk pool for the forecast period •For the long-run average period, internal risk ratings based on borrower characteristics	•Property type, LTV and costs to sell	•Outstanding balances, commitment, contractual maturities and historical prepayment experience for loans
Consumer
Home equity / Residential real estate	•Borrower credit scores, delinquency status, origination vintage, LTV and contractual maturity	•Collateral characteristics, LTV and costs to sell	•Outstanding balances, contractual maturities and historical prepayment experience for loans •Current utilization and historical pre-default draw experience for lines
Automobile	•Borrower credit scores, delinquency status, borrower income, LTV and contractual maturity	•New vs. used, LTV and borrower credit scores	•Outstanding balances, contractual maturities and historical prepayment experience
Credit card	•Borrower credit scores, delinquency status, utilization, payment behavior and months on book	•Borrower credit scores and credit line amount	•Pay-down curves are developed using a pro-rata method and estimated using borrower behavior segments, payment ratios and borrower credit scores
Education / Other consumer	•Modeled using either discrete risk parameters or net charge-off and pay-down rates

The following matrix describes the key economic variables that are consumed during our forecast period by loan class, as well as other assumptions that are used for our reversion and long-run average approaches.

Loan Class	Forecast Period - Key Economic Variables	Reversion Method	Long-Run Average
Commercial
Commercial and industrial / Equipment lease financing	•GDP and Gross Domestic Investment measures, employment related variables and personal income and consumption measures	•Immediate reversion	•Average parameters determined based on internal and external historical data •Modeled parameters using long-run economic conditions for retail small balance obligors
Commercial real estate (CRE)	• CRE Price Index, unemployment rates, GDP, corporate bond yield and interest rates	• Immediate reversion	• Average parameters determined based on internal and external historical data
Consumer
Home equity / Residential real estate	•Unemployment rates, HPI and interest rates	•Straight-line over 3 years	•Modeled parameters using long-run economic conditions
Automobile	•Unemployment rates, HPI, personal consumption expenditure and Manheim used car index	•Straight-line over 1 year	•Average parameters determined based on internal and external historical data
Credit card	•Unemployment rates, personal consumption expenditure and HPI	•Straight-line over 2 years	•Modeled parameters using long-run economic conditions
Education / Other consumer	•Modeled using either discrete risk parameters or net charge-off and pay-down rates

After the forecast period, we revert to the long-run average over the reversion period noted above, which is the period between the end of the forecast period and when losses are estimated to have completely reverted to the long-run average.

Once we have developed a combined estimate of credit losses (i.e., for the forecast period, reversion period and long-run average) under each of the forecasted scenarios, we produce a probability-weighted credit loss estimate by loan class. We then add or deduct any qualitative components and other adjustments, such as individually assessed loans, to produce the ALLL. See the Individually Assessed Component and Qualitative Component discussions that follow in this Note 1 for additional information about those adjustments.

Discounted Cash Flow

Prior to January 1, 2023, we used a discounted cash flow methodology for our home equity and residential real estate loan classes. Effective January 1, 2023, we discontinued our use of a discounted cash flow methodology, and we now use a pooled expected loss methodology based upon the quantification of risk parameters, such as PD, LGD and EAD for a loan or loan segment. See Note 1 Accounting Policies in our 2022 Form 10-K for a description of our use of a discounted cash flow methodology prior to January 1, 2023.

Individually Assessed Component

Loans and leases that do not share similar risk characteristics with a pool of loans are individually assessed as follows:

•For commercial nonperforming loans greater than or equal to a defined dollar threshold, reserves are based on an analysis of the present value of the loan’s expected future cash flows or the fair value of the collateral, if appropriate under our policy for collateral dependent loans. Nonperforming commercial loans below the defined threshold are reserved for under a pooled basis.

•For consumer nonperforming loans classified as collateral dependent, charge-off and ALLL related to recovery of amounts previously charged-off are evaluated through an analysis of the fair value of the collateral less costs to sell.

Qualitative Component

While our reserve methodologies strive to reflect all relevant credit risk factors, there continues to be uncertainty associated with, but not limited to, potential imprecision in the estimation process due to the inherent time lag of obtaining information and normal variations between expected and actual outcomes. We may hold additional reserves that are designed to provide coverage for losses

attributable to such risks. The ACL also takes into account factors that may not be directly measured in the determination of individually assessed or pooled reserves. Such qualitative factors may include, but are not limited to:

•Industry concentrations and conditions,

•Changes in market conditions, including regulatory and legal requirements,

•Changes in the nature and volume of our portfolio,

•Recent credit quality trends,

•Recent loss experience in particular portfolios, including specific and unique events,

•Recent macroeconomic factors that may not be reflected in the forecast information,

•Limitations of available input data, including historical loss information and recent data such as collateral values,

•Model imprecision and limitations,

•Changes in lending policies and procedures, including changes in loss recognition and mitigation policies and procedures, and

•Timing of available information.

Purchased Credit Deteriorated Loans or Securities

The allowance for PCD loans or securities is determined at the time of acquisition, as the estimated expected credit loss of the outstanding balance or par value, based on the methodologies described previously for loans and securities. In accordance with CECL, the allowance recognized at acquisition is added to the acquisition date purchase price to determine the asset’s amortized cost basis.

Allowance for Unfunded Lending Related Commitments

We maintain the allowance for unfunded lending related commitments on off-balance sheet credit exposures that are not unconditionally cancelable (e.g., unfunded loan commitments, letters of credit and certain financial guarantees), at a level we believe is appropriate as of the balance sheet date to absorb expected credit losses on these exposures. Other than the estimation of the probability of funding, this reserve is estimated in a manner similar to the methodology used for determining reserves for loans and leases. See the Allowance for Loan and Lease Losses section of this Note 1 for the key credit risk characteristics for unfunded lending related commitments. The allowance for unfunded lending related commitments is recorded as a liability on the Consolidated Balance Sheet. Net adjustments to this reserve are included in the provision for credit losses.

Accrued Interest

Accrued Interest

When accrued interest is reversed or charged-off in a timely manner, the CECL standard provides a practical expedient to exclude

accrued interest from ACL measurement. We consider our nonaccrual and charge-off policies to be timely for all of our investment

securities, loans and leases, with the exception of consumer credit cards, education loans and certain unsecured consumer lines of credit. We consider the length of time before nonaccrual/charge-off and the use of appropriate other triggering events for nonaccrual and charge-offs in making this determination. Pursuant to these policy elections, we calculate reserves for accrued interest on credit cards, education loans and certain unsecured consumer lines of credit, which are then included within the ALLL. See the Debt Securities section of Note 1 Accounting Policies in our 2022 Form 10-K and the Nonperforming Loans and Leases section of this Note 1 for additional information on our nonaccrual and charge-off policies.
