Notes to Consolidated Financial Statements(Unaudited)

2. Significant Accounting Policies

For a detailed discussion about the Firm’s significant accounting policies and for further information on accounting updates adopted in the prior year, see Note 2 to the financial statements in the 2023 Form 10-K.

In the first quarter of 2024, the Firm implemented certain presentation changes that impacted interest income and interest expense but had no effect on net interest income. These changes were made to align the accounting treatment between the balance sheet and the related interest income or expense, primarily by offsetting interest income and expense for certain prime brokerage-related customer receivables and payables that are currently accounted for as a single unit of account on the balance sheet. The current and previous presentation of these interest income and interest expense amounts are acceptable and the change does not represent a change in accounting principle. These changes were applied retrospectively to the income statement in 2023 and accordingly, prior period amounts were adjusted to conform with the current presentation.

During the three months ended March 31, 2024 there were no significant updates to the Firm’s significant accounting policies, other than for the accounting updates adopted.

Accounting Updates Adopted in 2024

Investments - Tax Credit Structures

The Firm adopted the Investments - Equity Method and Joint Ventures - Tax Credit Structures accounting update on January 1, 2024 using the modified retrospective method. This accounting update permits an election to account for tax equity investments using the proportional amortization method if certain conditions are met. Under the proportional amortization method, the initial cost of the investment is amortized in proportion to the income tax credits and other income tax benefits received and recognized net in the income statement as a component of provision for income taxes. The update requires a separate accounting policy election to be made for each tax credit program. Additional disclosures are required regarding (i) the nature of our tax equity investments and (ii) the effect of our tax equity investments and related income tax credits on the financial condition and results of operations (see Note 10).

The adoption resulted in a decrease to Retained earnings of $60 million as of January 1, 2024, net of tax, and a corresponding reduction to Other assets.
