Please answer the given financial question based on the context.
Context: bank holding companies and banks must have basel i capital ratios of at least 6% ( 6 % ) for tier 1 risk-based , 10% ( 10 % ) for total risk- based , and 5% ( 5 % ) for leverage . the basel ii framework , which was adopted by the basel committee on banking supervision in 2004 , seeks to provide more risk-sensitive regulatory capital calculations and promote enhanced risk management practices among large , internationally active banking organizations . the u.s . banking agencies initially adopted rules to implement the basel ii capital framework in 2004 . in july 2013 , the u.s . banking agencies adopted final rules ( referred to as the advanced approaches ) that modified the basel ii framework effective january 1 , 2014 . see item 1 business 2013 supervision and regulation and item 1a risk factors in this report . prior to fully implementing the advanced approaches established by these rules to calculate risk-weighted assets , pnc and pnc bank , n.a . must successfully complete a 201cparallel run 201d qualification phase . both pnc and pnc bank , n.a . entered this parallel run phase under the basel ii capital framework on january 1 , 2013 . this phase must last at least four consecutive quarters , although , consistent with the experience of other u.s . banks , we currently anticipate a multi-year parallel run period . in july 2013 , the u.s . banking agencies also adopted final rules that : ( i ) materially modify the definition of , and required deductions from , regulatory capital ( referred to as the basel iii rule ) ; and ( ii ) revise the framework for the risk-weighting of assets under basel i ( referred to as the standardized approach ) . the basel iii rule became effective for pnc on january 1 , 2014 , although many of its provisions are phased-in over a period of years , with the rules generally becoming fully effective on january 1 , 2019 . the standardized approach rule becomes effective on january 1 , 2015 . tier 1 common capital as defined under the basel iii rule 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% ( 10 % ) , or in the aggregate exceed 15% ( 15 % ) , of the institution 2019s adjusted tier 1 common capital . also , basel i regulatory capital excludes 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 2019s capital . the basel iii final rule also eliminates the tier 1 treatment of trust preferred securities for bank holding companies with $ 15 billion or more in assets . in the third quarter of 2013 , we concluded our redemptions of the discounted trust preferred securities assumed through acquisitions . see item 1 business- supervision and regulation and note 14 capital securities of subsidiary trusts and perpetual trust securities in the notes to consolidated financial statements in item 8 of this report for additional discussion of our previous redemptions of trust preferred securities . we provide information below regarding pnc 2019s pro forma fully phased-in basel iii tier 1 common capital ratio under both the advanced approaches and standardized approach frameworks and how it differs from the basel i tier 1 common capital ratios shown in table 18 above . after pnc exits parallel run , its regulatory basel iii risk-based capital ratios will be the lower of the ratios as calculated under the standardized and advanced approaches . table 19 : estimated pro forma fully phased-in basel iii tier 1 common capital ratio dollars in millions december 31 december 31 .
