April  5,  2017     Insurance  Commissioner  Dave  Jones   California  Department  of  Insurance     300  Capitol  Mall,  17th  Floor   Sacramento,  CA  95814       Re:  Petition  for  Investigation     Dear  Commissioner  Jones:     An  analysis  by  ProPublica  published  today  concludes  that  some  auto  insurance  companies   doing  business  in  California  are  overcharging  some  motorists  by  10%  or  more  solely   because  they  live  in  predominantly  minority  neighborhoods.       As  you  know,  Proposition  103  bars  insurance  companies  from  basing  a  motorist’s   premiums  primarily  upon  geographic  location.  Finding  that  “the  existing  laws  inadequately   protect  consumers  and  allow  insurance  companies  to  charge  excessive,  unjustified  and   arbitrary  rates,”  California  voters  established  a  process  under  which  the  formula  used  by   insurance  companies  to  set  auto  insurance  premiums  is  strictly  regulated.  Insurance  Code   section  1861.02(a)  requires  that  premiums  be  determined  principally  by  three  specified   rating  factors  –  the  insured’s  driving  safety  record,  annual  mileage,  and  years  of  driving   experience  –  and,  to  a  lesser  extent,  by  any  optional  rating  factors  that  “the  commissioner   may  adopt  by  regulation  and  that  have  a  substantial  relationship  to  the  risk  of  loss.”  (Ins.   Code  §  1861.02(a)(4).)  The  use  of  any  rating  factor  that  has  not  been  adopted  by  the   Commissioner  by  regulation  “shall  constitute  unfair  discrimination,”  which  is  a  violation  of   section  1861.05(a).     California’s  results  are  better  than  the  other  states  ProPublica  reviewed.  Still,  if   ProPublica’s  analysis  is  correct,  some  insurance  companies  –  notably  Liberty  Mutual,   Farmers,  Nationwide  and  USAA  –  are  overcharging  motorists  in  violation  of  Proposition   103,  the  Unruh  Civil  Rights  Act  and  other  California  laws.     While  objections  have  been  raised  to  the  methodology  used  in  ProPublica’s  analysis,  the   study  itself  explains  that  ProPublica  was  unable  to  obtain  all  the  data  necessary  to  precisely   confirm  its  conclusions  because  insurance  companies  are  not  required  to  disclose  their   actual  loss  data  by  zip  code.  Absent  that  information,  there  is  no  way  to  determine  whether   insurance  companies  are  complying  with  California  law.       Pursuant  to  Insurance  Code  sections  1861.02,  1861.05  and  12921,  we  therefore  request   that  you  immediately  convene  a  formal  public  inquiry  to  investigate  this  matter.  The  first     step  should  be  to  require  auto  insurance  companies  to  submit  the  required  data  for  each   zip  code  in  California.     Sincerely,   Harvey  Rosenfield                 Carmen  Balber
