( 2 ) under the advanced approaches framework eligible credit reserves that exceed expected credit losses are eligible for inclusion in tier 2 capital to the extent the excess reserves do not exceed 0.6% ( 0.6 % ) of credit risk-weighted assets , which differs from the standardized approach in which the allowance for credit losses is eligible for inclusion in tier 2 capital up to 1.25% ( 1.25 % ) of credit risk-weighted assets , with any excess allowance for credit losses being deducted in arriving at credit risk-weighted assets .
( 3 ) as of december 31 , 2015 and december 31 , 2014 , citi 2019s common equity tier 1 capital , tier 1 capital , and total capital ratios were the lower derived under the basel iii advanced approaches framework .
( 4 ) citi 2019s basel iii capital ratios and related components , on a fully implemented basis , are non-gaap financial measures .
