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 .

basel iii advanced approaches risk-weighted assets were estimated based on the advanced approaches rules and application of basel ii.5 , and reflect credit , market and operational risk .
basel iii standardized approach risk- weighted assets were estimated based on the standardized approach rules and reflect credit and market risk .
as a result of the staggered effective dates of the final u.s .
capital rules issued in july 2013 , as well as the fact that pnc remains in the parallel run qualification phase for the advanced approaches , pnc 2019s regulatory risk-based capital ratios in 2014 will be based on the definitions of , and deductions from , capital under basel iii ( as such definitions and deductions are phased-in for 2014 ) and basel i risk- weighted assets ( but subject to certain adjustments as defined by the basel iii rules ) .
we refer to the capital ratios calculated using these basel iii phased-in provisions and basel i risk- weighted assets as the transitional basel iii ratios .
