Recent accounting pronouncements
Purchased Loans
In November 2025, the FASB issued guidance within ASU 2025-08, Financial Instruments - Credit Losses (Topic 326): Purchased Loans. The amendments in this update are intended to improve decision usefulness and comparability of financial reporting for acquired financial assets while retaining the measurement, presentation or disclosure requirements outlined in ASC 326. The update introduces the concept of "purchased seasoned loans," which refers to non-PCD loans acquired in a business combination or in an asset acquisition more than 90 days after their origination date. The amendments align the accounting for purchased seasoned loans with the gross-up methodology applied to PCD loans, whereby the initial estimate of credit losses is amortized over the life of the loan as a reduction to interest income, rather than being recognized immediately in earnings as credit loss expense. The update also includes an accounting policy election related to the subsequent measurement of expected credit losses on purchased seasoned loans for entities using a method other than a discounted cash flow analysis. Under this election, entities may use the amortized cost basis of the asset, rather than the unpaid principal balance to estimate credit losses on these loans.

The changes aim to make the recognition and capitalization of software costs more consistent across different development methodologies and eliminates the requirement to assess software development costs based on predefined project stages (e.g., preliminary, application development, post-implementation). The update requires entities to start capitalizing software costs when management has authorized and committed to funding the software project, it is probable the project will be completed, and the software will be used to perform the intended function.

The amendments in this update require disclosure, in the notes to financial statements, of specified information about certain costs and expenses. Entities will be required to disclose the amounts of employee compensation, depreciation, and intangible asset amortization included in each relevant expense caption. The update also requires entities to include certain amounts that are already required to be disclosed under current GAAP in the same disclosure as the other disaggregation requirements, disclose a qualitative description of the amounts remaining in relevant expense captions that are not separately disaggregated quantitatively, and disclose the total amount of selling expenses and, in annual reporting periods, an entity’s definition of selling expenses.

Public business entities will be required to disclose on an annual basis, specific categories in the rate reconciliation and provide additional information for reconciling items that meet or exceed a five percent threshold (computed by multiplying pretax income by the applicable statutory income tax rate) and include disclosure of state and local jurisdictions that make up the majority of the state and local income tax category in the rate reconciliation.

The amendments in this update are incremental and require public entities that report segment information to disclose, on an annual and interim basis, significant segment expenses that are regularly provided to the chief operating decision maker and included within each reported measure of segment profit or loss as well as other segment items. Annual disclosure of the title and position of the chief operating decision maker and how the reported measures of segment profit or loss are used to assess performance and allocation of resources is also required.

About New Standards Disclosures
New accounting standards disclosures describe recently adopted pronouncements and those not yet effective, along with management's assessment of their expected impact. This section provides an early warning system for upcoming changes to how a company reports its financial results, often years before the new rules take effect.
Key signals: when management describes a not-yet-adopted standard's impact as "material" or "still being evaluated," it signals potential significant changes to reported metrics upon adoption. Watch for standards that affect a company's core operations — for example, revenue recognition changes for software companies or lease accounting changes for retailers with large store footprints. The transition method chosen (full retrospective versus modified retrospective) affects comparability with prior periods. Companies that delay adoption to the latest permitted date may be struggling with implementation complexity. Compare the disclosed impact assessments against peers in the same industry to gauge whether management's expectations are reasonable.
