The following table presents the regulatory capital structure, total risk-weighted assets, related regulatory capital ratios and the minimum required regulatory capital ratios for State Street 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 final rule are phased in, the ratios presented in the table for each period-end are not directly comparable.

⁽¹⁾CET1 capital, tier 1 capital and total capital ratios as of December 31, 2017 and December 31, 2016 were calculated in conformity with the advanced approaches provisions of the Basel III final rule. Tier 1 leverage ratio as of December 31, 2017 and December 31, 2016 were calculated in conformity with the Basel III final rule.

⁽²⁾CET1 capital, tier 1 capital and total capital ratios as of December 31, 2017 and December 31, 2016 were calculated in conformity with the standardized approach provisions of the Basel III final rule. Tier 1 leverage ratio as of December 31, 2017 and December 31, 2016 were calculated in conformity with the Basel III final rule.

⁽³⁾Amounts for State Street and State Street Bank as of December 31, 2017 consisted of goodwill, net of associated deferred tax liabilities, and 80% of other intangible assets, net of associated deferred tax liabilities. Amounts for State Street and State Street Bank as of December 31, 2016 consisted of goodwill, net of deferred tax liabilities and 60% of other intangible assets, net of associated deferred tax liabilities. Intangible assets, net of associated deferred tax liabilities is phased in as a deduction from capital, in conformity with the Basel III final rule.

⁽⁴⁾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 risk RWA under the advanced approaches depending on the severity of the loss event and its categorization among the seven Basel-defined UOMs.

⁽⁵⁾Market risk risk-weighted assets reported in conformity with the Basel III advanced approaches included a CVA which reflected the risk of potential fair value adjustments for credit risk reflected in our valuation of over-the-counter derivative contracts. The CVA was not provided for in the final market risk capital rule; however, it was required by the advanced approaches provisions of the Basel III final rule. We used a simple CVA approach in conformity with the Basel III advanced approaches.

⁽⁶⁾Minimum requirements will be phased in up to full implementation beginning on January 1, 2019; minimum requirements listed are as of December 31, 2017.

⁽⁷⁾Minimum requirements will be phased in up to full implementation beginning on January 1, 2019; minimum requirements listed are as of December 31, 2016.
