Question: what percent of the ratings profile of derivative receivables were junk rated in 2013?
Evidence:
table_4: rating equivalent december 31 ( in millions except ratios ) the bb+/ba1 to b-/b3 of rating equivalent exposure net of all collateral is 6384 ; the bb+/ba1 to b-/b3 of rating equivalent % ( % ) of exposure net of all collateral is 11 ; the bb+/ba1 to b-/b3 of exposure net of all collateral is 6806 ; the bb+/ba1 to b-/b3 of % ( % ) of exposure net of all collateral is 13 ;
table_5: rating equivalent december 31 ( in millions except ratios ) the ccc+/caa1 and below of rating equivalent exposure net of all collateral is 837 ; the ccc+/caa1 and below of rating equivalent % ( % ) of exposure net of all collateral is 1 ; the ccc+/caa1 and below of exposure net of all collateral is 3415 ; the ccc+/caa1 and below of % ( % ) of exposure net of all collateral is 7 ;
