revised capital framework the u.s .federal bank regulatory agencies ( agencies ) have approved revised risk-based capital and leverage ratio regulations establishing a new comprehensive capital framework for u.s .banking organizations ( revised capital framework ) .these regulations are largely based on the basel committee 2019s december 2010 final capital framework for strengthening international capital standards ( basel iii ) and also implement certain provisions of the dodd-frank act .under the revised capital framework , group inc .is an 201cadvanced approach 201d banking organization .below are the aspects of the rules that are most relevant to the firm , as an advanced approach banking organization .definition of capital and capital ratios .the revised capital framework introduced changes to the definition of regulatory capital , which , subject to transitional provisions , became effective across the firm 2019s regulatory capital and leverage ratios on january 1 , 2014 .these changes include the introduction of a new capital measure called common equity tier 1 ( cet1 ) , and the related regulatory capital ratio of cet1 to rwas ( cet1 ratio ) .in addition , the definition of tier 1 capital has been narrowed to include only cet1 and instruments such as perpetual non- cumulative preferred stock , which meet certain criteria .certain aspects of the revised requirements phase in over time .these include increases in the minimum capital ratio requirements and the introduction of new capital buffers and certain deductions from regulatory capital ( such as investments in nonconsolidated financial institutions ) .in addition , junior subordinated debt issued to trusts is being phased out of regulatory capital .the minimum cet1 ratio is 4.0% ( 4.0 % ) as of january 1 , 2014 and will increase to 4.5% ( 4.5 % ) on january 1 , 2015 .the minimum tier 1 capital ratio increased from 4.0% ( 4.0 % ) to 5.5% ( 5.5 % ) on january 1 , 2014 and will increase to 6.0% ( 6.0 % ) beginning january 1 , 2015 .the minimum total capital ratio remains unchanged at 8.0% ( 8.0 % ) .these minimum ratios will be supplemented by a new capital conservation buffer that phases in , beginning january 1 , 2016 , in increments of 0.625% ( 0.625 % ) per year until it reaches 2.5% ( 2.5 % ) on january 1 , 2019 .the revised capital framework also introduces a new counter-cyclical capital buffer , to be imposed in the event that national supervisors deem it necessary in order to counteract excessive credit growth .risk-weighted assets .in february 2014 , the federal reserve board informed us that we have completed a satisfactory 201cparallel run , 201d as required of advanced approach banking organizations under the revised capital framework , and therefore changes to rwas will take effect beginning with the second quarter of 2014 .accordingly , the calculation of rwas in future quarters will be based on the following methodologies : 2030 during the first quarter of 2014 2014 the basel i risk-based capital framework adjusted for certain items related to existing capital deductions and the phase-in of new capital deductions ( basel i adjusted ) ; 2030 during the remaining quarters of 2014 2014 the higher of rwas computed under the basel iii advanced approach or the basel i adjusted calculation ; and 2030 beginning in the first quarter of 2015 2014 the higher of rwas computed under the basel iii advanced or standardized approach .goldman sachs 2013 annual report 191 .
