On January 1, 2023 Northern Trust adopted Accounting Standard Update (ASU) No. 2022-01, “Derivatives and Hedging (Topic 815): Fair Value Hedging—Portfolio Layer Method” (ASU 2022-01). The amendments in ASU 2022-01 expand the current last-of-layer hedging model from a single-layer method to allow multiple hedged layers of a single closed portfolio. To reflect that expansion, the last-of-layer method is renamed the portfolio layer method. In addition, ASU 2022-01 (1) expands the scope of the portfolio layer method to include non-prepayable assets, (2) specifies eligible hedging instruments in a single-layer hedge, (3) provides additional guidance on the accounting for and disclosure of hedge basis adjustments under the portfolio layer method and (4) specifies how hedge basis adjustments should be considered when determining credit losses for the assets included in the closed portfolio. Upon adoption of ASU 2022-01, there was no impact to Northern Trust’s consolidated balance sheets or consolidated statements of income.

On January 1, 2023 Northern Trust adopted ASU No. 2022-02, “Financial Instruments—Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures” (ASU 2022-02). The amendments in ASU 2022-02 eliminate the accounting guidance for troubled debt restructurings (TDRs) for creditors that have adopted the current expected credit losses accounting standard while enhancing disclosure requirements for certain loan refinancings and restructurings made to borrowers experiencing financial difficulty. In addition, ASU 2022-02 requires that a public business entity disclose current-period gross charge-offs by year of origination for financing receivables and net investment in leases. Upon adoption of ASU 2022-02, there was no significant impact to Northern Trust’s consolidated balance sheets or consolidated statements of income. Please refer to Note 5—Loans for further information.

On January 1, 2023 Northern Trust adopted ASU No. 2022-04, “Liabilities—Supplier Finance Programs (Topic 405-50): Disclosure of Supplier Finance Program Obligations” (ASU 2022-04). The amendments in ASU 2022-04 enhance the transparency about the use of supplier finance programs for investors or other allocators of capital. Specifically, ASU 2022-04 requires that a buyer in a supplier finance program disclose sufficient qualitative and quantitative information about the program to allow a user of financial statements to understand the program’s nature, activity during the period, changes from period to period, and potential magnitude. Upon adoption of ASU 2022-04, there was no impact to Northern Trust’s consolidated balance sheets or consolidated statements of income.
