Criteria
The credit ratings of available credit rating agencies on Wikirating are converted to numbers (from 0 to 100) and mapped to the Wikirating credit rating scale. The adjusted credit ratings are based on the average of all available rating values.
Calculations
For each corporation the average of available credit rating values from credit rating agencies (CRA(i)) is taken:
{\displaystyle Rating(Corporation)_{CAI}=Avg\lbrace Rating(Corporation)_{CRA(1)},Rating(Corporation)_{CRA(2)},…\rbrace }
