Changes in Accounting Principles and Effects of New Accounting Pronouncements

Standard / Adoption Date	Description	Effects on the Financial Statements
Standards Not Yet Adopted
Troubled Debt Restructurings and Vintage Disclosures January 1, 2023	Eliminates the accounting guidance for TDRs, while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors made to borrowers experiencing financial difficulty. Additionally, requires disclosure of current-period gross write-offs by year of origination for financing receivables and net investment in leases.	Truist has created a project plan and is actively engaged with its lines of business to establish reporting mechanisms consistent with the requirements of this standard. While implementation efforts are ongoing, the Company does not expect that the implementation of this standard will have a material impact on the Company. Upon adoption, Truist expects the newly required disclosures to be included in the Loans and ACL footnote.
Fair Value Hedging – Portfolio Layer Method January 1, 2023	Introduces the portfolio layer method, which expands the current single-layer method to allow multiple hedged layers of a single closed portfolio under the method (previously named, last-of-layer method). Additionally, expands the scope of the portfolio layer method to include non-prepayable assets, specifies eligible hedging instruments in a single-layer hedge, provides additional guidance on the accounting for and disclosure of hedge basis adjustments under the portfolio layer method, specifies how hedge basis adjustments should be considered when determining credit losses for the assets included in the closed portfolio.	Truist is continuing to evaluate the use of the portfolio layer method in its hedging programs, although future use of the standard is dependent on its asset-liability management strategies in the context of the then current interest rate outlook. Truist does not believe adoption of the standard will have a material impact on its active last-of-layer hedges.
