Regulatory Capital (Tables)

12 Months Ended

Dec. 31, 2019

The following table presents the regulatory capital structure, total RWA, related regulatory capital ratios and the minimum required regulatory capital ratios for us and State Street Bank as of the dates indicated. As a result of changes in the methodologies used to calculate our regulatory capital ratios from period to period as the provisions of the Basel III rule were phased in, the ratios presented in the table for each period-end are not directly comparable. Refer to the footnotes following the table.

⁽¹⁾ Other adjustments within CET1 primarily include the overfunded portion of the firm’s defined benefit pension plan obligation net of associated deferred tax liabilities, disallowed deferred tax assets, and other required credit risk based deductions.

⁽²⁾Includes a CVA which reflects the risk of potential fair value adjustments for credit risk reflected in our valuation of OTC derivative contracts. We used a simple CVA approach in conformity with the Basel III advanced approaches.

⁽³⁾ Under the current advanced approaches rules and regulatory guidance concerning operational risk models, RWA attributable to operational risk can vary substantially from period-to-period, without direct correlation to the effects of a particular loss event on our results of operations and financial condition and impacting dates and periods that may differ from the dates and periods as of and during which the loss event is reflected in our financial statements, with the timing and categorization dependent on the processes for model updates and, if applicable, model revalidation and regulatory review and related supervisory processes. An individual loss event can have a significant effect on the output of our operational RWA under the advanced approaches depending on the severity of the loss event and its categorization among the seven Basel-defined UOMs.

⁽⁴⁾Minimum requirements were phased in with full implementation beginning on January 1, 2019; minimum requirements listed are as of December 31, 2019.

⁽⁵⁾Minimum requirements were phased in with full implementation beginning on January 1, 2019; minimum requirements listed are as of December 31, 2018.
