(b) Pro forma Basel III Tier 1 common capital ratio estimate not provided in 3Q12. We provide information below regarding PNC’s pro forma fully phased-in Basel III Tier 1 common capital ratio and how it differs from the Basel I Tier 1 common capital ratio. This Basel III ratio, which is calculated using PNC's estimated risk-weighted assets under the Basel III advanced approaches, will replace the current Basel I ratio for this regulatory metric when PNC exits the parallel run qualification phase. The Federal Reserve Board announced final rules implementing Basel III on July 2, 2013. Our estimate of Basel III capital information set forth below is based on our understanding of the final Basel III rules. Tier 1 common capital as defined under the Basel III rules differs materially from Basel I. For example, under Basel III, significant common stock investments in unconsolidated financial institutions, mortgage servicing rights and deferred tax assets must be deducted from capital to the extent they individually exceed 10%, or in the aggregate exceed 15%, of the institution's adjusted Tier 1 common capital. Also, Basel I regulatory capital excludes certain other comprehensive income related to both available for sale securities and pension and other postretirement plans, whereas under Basel III these items are a component of PNC's capital. Basel III risk-weighted assets were estimated under the advanced approaches included in the Basel III rules and application of Basel II.5, and reflect credit, market and operational risk. PNC utilizes this capital ratio estimate to assess its Basel III capital position (without the benefit of phase-ins), including comparison to similar estimates made by other financial institutions. This Basel III capital estimate is likely to be impacted by any additional regulatory guidance, continued analysis by PNC as to the application of the rules to PNC, and the ongoing evolution, validation and regulatory approval of PNC's models integral to the calculation of advanced approaches risk-weighted assets. |
