Summary of Significant Accounting Policies (Policies)

6 Months Ended

Jun. 30, 2016

Basis of Presentation:

The accounting and financial reporting policies of State Street Corporation conform to U.S. GAAP. State Street Corporation, the parent company, is a financial holding company headquartered in Boston, Massachusetts. Unless otherwise indicated or unless the context requires otherwise, all references in these notes to consolidated financial statements to “State Street,” “we,” “us,” “our” or similar references mean State Street Corporation and its subsidiaries on a consolidated basis. Our principal banking subsidiary is State Street Bank.

The accompanying Consolidated Financial Statements should be read in conjunction with the financial and risk factor information included in our 2015 Form 10-K, which we previously filed with the SEC.

Consolidation

The consolidated financial statements accompanying these condensed notes are unaudited. In the opinion of management, all adjustments, consisting only of normal recurring adjustments, which are necessary for a fair statement of the consolidated results of operations in these financial statements, have been made. Certain previously reported amounts presented in this Form 10-Q have been reclassified to conform to current-period presentation. 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-Q with the SEC.

The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions in the application of certain of our significant accounting policies that may materially affect the reported amounts of assets, liabilities, equity, revenue, and expenses. As a result of unanticipated events or circumstances, actual results could differ from those estimates. These accounting estimates reflect the best judgment of management, but actual results could differ.

Our consolidated statement of condition as of December 31, 2015 included in the accompanying consolidated financial statements was derived from the audited financial statements as of that date, but does not include all notes required by U.S. GAAP for a complete set of consolidated financial statements.

Recent Accounting Developments

Recent Accounting Developments:



Relevant standards that were recently issued but not yet adopted
Standard	Description	Date of Adoption	Effects on the financial statements or other significant matters
ASU 2014-09, Revenue from Contracts with Customers (Topic 606)	The standard, and its related amendments, will replace existing revenue recognition standards and significantly expand the disclosure requirements for revenue arrangements with customers. It may be adopted either retrospectively or on a modified retrospective basis to new contracts and existing contracts with remaining performance obligations as of the effective date.	January 1, 2018	We are currently assessing the impact of the standard and its amendments on our consolidated financial statements and evaluating the alternative methods of adoption.
ASU 2016-01, Financial Instruments-Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities	The standard makes limited amendments to the guidance on the classification and measurement of financial instruments. Under the new standard, all equity securities will be measured at fair value through earnings with certain exceptions, including investments accounted for under the equity method of accounting. In addition, the FASB clarified the guidance related to valuation allowance assessments when recognizing deferred tax assets on unrealized losses on available-for-sale debt securities. This standard must be applied on a retrospective basis.	January 1, 2018	We are currently assessing the impact of the standard on our consolidated financial statements.
ASU 2016-02, Leases (Topic 842)	The standard represents a wholesale change to lease accounting and requires all leases, other than short-term leases, to be reported on balance sheet through recognition of a right-of-use asset and a corresponding liability for future lease obligations. The standard also requires extensive disclosures for assets, expenses, and cash flows associated with leases, as well as a maturity analysis of lease liabilities.	January 1, 2019	We are currently assessing the impact of the standard on our consolidated financial statements, but we anticipate an increase in assets and liabilities due to the recognition of the required right-of-use asset and corresponding liability for all lease obligations that are currently classified as operating leases, as well as additional disclosure on our leases.
ASU 2016-05, Derivatives and Hedging (Topic 815): Effect of Derivative Contract Novations on Existing Hedge Accounting Relationships (a consensus of the Emerging Issues Task Force)	The standard clarifies that a change in the counterparty to a derivative instrument that is designated as a hedging instrument would result in dedesignation of the hedging relationship. This may be applied on a prospective or modified retrospective basis.	January 1, 2017	Our adoption of the standard will not have a material impact on our consolidated financial statements.
ASU 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting	The standard simplifies the guidance related to stock compensation, including the accounting for income taxes by eliminating the windfall pool and requiring recognition of all excess tax benefits and deficiencies within the statement of income, as well as changes in the accounting for forfeitures, classification in the statement of cash flows and tax withholding requirements.	January 1, 2017	We anticipate increased income statement volatility due to the recognition of all excess tax benefits and deficiencies within the statement of income. We do not anticipate early adoption of this standard.
ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments	The standard requires all expected credit losses for financial assets held at the reporting date to be measured based on historical experience, current conditions, and reasonable supportable forecasts. The standard will utilize forward-looking information to determine credit loss estimates. It will require immediate recognition of the full amount of credit losses that are expected for certain financial assets.	January 1, 2020	We are currently assessing the impact of the standard on our consolidated financial statements.

Relevant standards that were adopted during the six months ended June 30, 2016:

We adopted ASU 2015-02, Consolidation (Topic 810): Amendments to the Consolidation Analysis, effective January 1, 2016. The implementation of the new standard did not result in any changes to our previous consolidation conclusions.

We adopted ASU 2015-03, Simplifying the Presentation of Debt Issuance Costs, effective January 1, 2016 with retrospective application for all prior periods presented. The implementation of this standard resulted in debt issuance costs of $41 million and $37 million as of June 30, 2016 and December 31, 2015, respectively, being netted against long-term debt in our consolidated statement of condition.
