On December 16, 2014, CFA sent a letter commenting on an Allstate auto insurance filing in Wisconsin. CFA writes today concerning a similar filing in Tennessee. CFA has previously alerted state insurance commissioners to the dangers of Price Optimization, which would be used to produce unfairly discriminatory rates, illegal in every state. CFA now has proof, in the form of Allstate rate filings from several states, that unfair pricing through so-called “optimization” is occurring.
