Table 23: Accruing Loans Past Due (a)

(a)Past due loan amounts include government insured or guaranteed loans of $0.4 billion at both December 31, 2023 and 2022.

Accruing loans past due 90 days or more continue to accrue interest because they are (i) well secured by collateral and are in the process of collection, (ii) managed in homogeneous portfolios with specified charge-off timeframes adhering to regulatory guidelines, or (iii) certain government insured or guaranteed loans. As such, they are excluded from nonperforming loans.

Loan Modifications

We provide relief to our customers experiencing financial hardships through a variety of solutions. Commercial loan and lease modifications are based on each individual borrower’s situation, while consumer loan modifications are evaluated under our hardship relief programs.

On January 1, 2023, we adopted ASU 2022-02 Financial Instruments -Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures, which eliminates the accounting guidance for TDRs and enhances the disclosure requirements for certain loan modifications when a borrower is experiencing financial difficulty. Refer to Note 1 Accounting Policies and Note 3 Loans and Related Allowance for Credit Losses for additional information on our adoption of this ASU.

Our determination of the ACL is based on historical loss and performance experience, current economic conditions, the reasonable and

supportable forecasts of future economic conditions and other relevant factors, including current borrower and/or transaction characteristics and assessments of the remaining estimated contractual term as of the balance sheet date. 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.

Expected losses are estimated primarily 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) long run average expected losses for the remaining estimated contractual term.

We use forward-looking information in estimating expected credit losses for our reasonable and supportable forecast period. For this purpose, we have established a framework which includes a three-year forecast period and the use of four economic scenarios and associated probability weights, which in combination create a forecast of expected economic outcomes. Forward-looking information, such as forecasted relevant macroeconomic variables, is incorporated into the expected credit loss estimates using quantitative macroeconomic models, as well as through analysis from PNC’s economists and management’s 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 1-3 years, if not immediate.

The long-run average expected credit losses are derived from available historical credit information. We use long-run average expected losses for the portfolio over the estimated remaining contractual term beyond our reasonable and supportable forecast period and the reversion period.

Allowance for Loan and Lease Losses

Our pooled expected credit loss methodology is based upon the quantification of PD, LGD, EAD and the remaining estimated contractual term for a loan, loan segment or lease. We also consider the impact of prepayments and amortization on the estimated contractual term in our expected loss estimates. We use historical data, current borrower characteristics and forecasted economic variables in quantitative methods to estimate these risk parameters by loan, loan segment or lease. PDs represent a quantification of risk of the likelihood that a borrower may not be able to pay their contractual obligation over a defined period of time. LGD describes the estimated magnitude of potential loss if a borrower were to default, and EAD (or utilization rates for certain revolving loans) is the estimated balance outstanding at the expected time of default. These parameters are calculated for each forecasted scenario and the long-run average period, and are combined to generate expected loss estimates by scenario in proportion to the scenario weights.

Prior to January 1, 2023, we used a discounted cash flow methodology for our consumer real estate related loan classes and certain TDRs. Effective January 1, 2023, we discontinued our use of the discounted cash flow methodology, and we now use a pooled expected credit loss methodology as described above.

For loans and leases that do not share similar risk characteristics with a pool of loans, we establish individually assessed reserves using methods prescribed by GAAP. Reserves for individual commercial nonperforming loans exceeding a defined dollar threshold 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. Commercial nonperforming loans that are below the defined threshold are collectively reserved for, as we believe these loans continue to share similar risk characteristics. 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.

While our reserve models and methodologies strive to reflect all relevant expected 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. A portion of the allowance is related to qualitative measurement factors. These 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.

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 pooled loans and leases. 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 on the Consolidated Income Statement.
