Accounting Standards Update	Description	Financial Statement Impact
Reference Rate Reform - ASU 2020-04 Issued March 2020 Reference Rate Reform Scope - ASU 2021-01 Issued January 2021 Reference Rate Reform Deferral of Sunset Date – ASU 2022-06 Issued December 2022	• Provides optional expedients and exceptions for applying generally accepted accounting principles to contracts, hedging relationships and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform (codified in ASC 848). • Includes optional expedients related to contract modifications that allow an entity to account for modifications (if certain criteria are met) as if the modifications were only minor (assets within the scope of ASC 310, Receivables), were not substantial (assets within the scope of ASC 470, Debt) and/or did not result in remeasurements or reclassifications (assets within the scope of ASC 842, Leases, and other Topics) of the existing contract. • Includes optional expedients related to hedging relationships within the scope of ASC 815, Derivatives & Hedging, whereby changes to the critical terms of a hedging relationship do not require dedesignation if certain criteria are met. In addition, potential sources of ineffectiveness as a result of reference rate reform may be disregarded when performing some effectiveness assessments. • Includes optional expedients and exceptions for contract modifications and hedge accounting that apply to derivative instruments impacted by the market-wide discounting transition. • Guidance in these ASUs is effective as of March 12, 2020 through December 31, 2024.	• ASU 2020-04 was adopted March 12, 2020. ASU 2021-01 was retrospectively adopted October 1, 2020. ASU 2022-06 was adopted upon issuance. • During the fourth quarter of 2020, we elected to apply certain optional expedients for contract modifications and hedging relationships to derivative instruments impacted by the market-wide discounting transition. These optional expedients remove the requirement to remeasure contract modifications or dedesignate hedging relationships due to reference rate reform. The elections made in the fourth quarter of 2020 apply only to derivative instruments impacted by the market-wide discounting transition, not all derivative instruments. • During the first quarter of 2021, we elected to apply certain optional expedients to derivative instruments that were modified in the first quarter due to the adoption of fallback language recommended by the ISDA to address the anticipated cessation of LIBOR. These optional expedients remove the requirement to remeasure contract modifications or dedesignate hedging relationships due to reference rate reform. We applied these optional expedients consistently to all eligible LIBOR cessation-related contract modifications and hedging relationships since election. • During the fourth quarter of 2021, we elected to apply certain optional expedients for contract modifications to receivables modified in the fourth quarter due to the cessation of 1-week and 2-month USD LIBOR tenors and non-USD Interbank Offered Rates. These optional expedients remove the requirement to assess whether the contract modification was more-than-minor in accordance with ASC 310. We also elected to apply certain optional expedients related to assessing hedge effectiveness to our cash flow hedge relationships affected by reference rate reform. We applied these optional expedients consistently to all eligible LIBOR cessation-related contract modifications and hedging relationships since election. • During the second quarter of 2023, we elected and applied certain optional expedients for contract modifications and hedging relationships impacted by the central clearing counterparties conversion processes for LIBOR-indexed derivative instruments. These optional expedients remove the requirement to remeasure contract modifications or dedesignate hedging relationships due to reference rate reform. The elections made apply only to derivatives instruments impacted by the central clearinghouse conversion process. • During the second quarter of 2023, we applied certain optional expedients for investment security, debt and preferred stock instrument contract modifications impacted by LIBOR cessation. These optional expedients remove the requirement to remeasure contract modifications. • We may elect additional optional expedients for contract modifications and hedge relationships affected by reference rate reform through the effective date of this guidance.


Accounting Standards Update	Description	Financial Statement Impact
Troubled Debt Restructurings and Vintage Disclosures - ASU 2022-02 Issued March 2022	• Eliminates the accounting guidance for TDRs and requires an entity to apply the loan refinancing and restructuring guidance to determine whether a modification results in a new loan or a continuation of an existing loan. • Eliminates the requirement to use a discounted cash flow approach to measure the allowance for credit losses for TDRs. • Enhances disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty. • Requires disclosure of current-period gross charge-offs by year of origination for financing receivables and net investments in leases within the scope of CECL.	• Adopted January 1, 2023 using a modified retrospective transition approach for the amendments related to the recognition and measurement of TDRs. • The impact of adoption resulted in a decrease to the beginning period ALLL of $35 million, resulting in an increase to retained earnings of $26 million, net of tax, as of January 1, 2023. • The presentation of our loan modification disclosures have been updated to reflect information on loan modifications given to borrowers experiencing financial difficulty and can be found within Note 3 Loans and Related Allowance for Credit Losses. TDR disclosures are presented for comparative periods only and are not required to be updated in current periods. Additionally, our vintage disclosure has been updated to reflect gross charge-offs by year of origination.
Accounting Standards Update	Description	Financial Statement Impact
Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method – ASU 2023-02 Issued March 2023	• Permits reporting entities to elect to account for their tax equity investments, regardless of the tax credit program from which the income tax credits are received, using the proportional amortization method if certain conditions are met. • A reporting entity makes an accounting policy election to apply the proportional amortization method on a tax-credit-program-by-tax-credit-program basis rather than electing to apply the proportional amortization method at the reporting entity level or to individual investments.	• Early adopted September 30, 2023, using a modified retrospective transition approach for the amendments related to our tax credit programs that are eligible to apply proportional amortization. The cumulative effect to retained earnings as of January 1, 2023 was immaterial. • At adoption, we elected to apply the proportional amortization method to all qualifying investments in the NMTC program. PNC historically applied proportional amortization to LIHTC investments since applying ASU 2014-01. • See Note 4 Loan Sale and Servicing Activities and Variable Interest Entities for the impact of adoption.

(a)Gross charge-offs are presented on a year-to-date basis, as of the reporting date.

(b)Loans with no FICO score available or required generally refers to new accounts issued to borrowers with limited credit history, accounts for which we cannot obtain an updated FICO score (e.g., recent profile changes), cards issued with a business name and/or cards secured by collateral. Management proactively assesses the risk and size of this loan category and, when necessary, takes actions to mitigate the credit risk.

(c)Includes charge-offs of deposit overdrafts.
