ASU 2022-02 eliminated the accounting guidance for TDRs, while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty. Specifically, rather than applying the recognition and measurement guidance for TDRs, an entity must apply the loan refinancing and restructuring guidance to determine whether a modification results in a new loan or a continuation of an existing loan. Additionally, ASU 2022-02 requires an entity to disclose current-period gross write-offs by year of origination for financing receivables within the scope of Subtopic 326-20, “Financial Instruments—Credit Losses—Measured at Amortized Cost.” ASU 2022-02 did not have a material impact on our consolidated financial statements.</span></div>
