As a result of unanticipated events or circumstances, actual results could differ from those estimates. Events occurring subsequent to the date of our consolidated statement of condition were evaluated for potential recognition or disclosure in our consolidated financial statements through the date we filed this Form 10-K with the SEC. The following is a summary of our significant accounting policies.

Basis of Presentation: Our consolidated financial statements include the accounts of the parent company and its majority- and wholly-owned subsidiaries, including State Street Bank. All material inter-company transactions and balances have been eliminated. Certain previously reported amounts have been reclassified to conform to current year presentation. We consolidate subsidiaries in which we hold a majority of the voting rights or exercise control. Investments in unconsolidated subsidiaries, recorded in other assets, generally are accounted for under the equity method of accounting if we have the ability to exercise significant influence over the operations of the investee. For investments accounted for under the equity method, our share of income or loss is recorded in processing fees and other revenue in our consolidated statement of income. Investments not meeting the criteria for equity method treatment are accounted for under the cost method of accounting.

Foreign Currency Translation: The assets and liabilities of our operations with functional currencies other than the U.S. dollar are translated at month- end exchange rates, and revenues and expenses are translated at rates that approximate average monthly exchange rates. Gains or losses from the translation of the net assets of subsidiaries with functional currencies other than the U.S. dollar, net of related taxes, are recorded in accumulated other comprehensive income, a component of shareholders’ equity.
