TRBC is a market-based classification scheme, similar to the GICS and ICB systems.
TRBC is used primarily in the Financial Investment and Advisory space, where investors identify and select groups of comparable companies and look at trends.
More specifically, this could be Investment Managers allocating funds and benchmarking their portfolios; Investment Bankers highlighting acquisition targets and opportunities for financial restructuring, or more generally corporates performing competitive analysis of their peers in the marketplace.
TRBC covers over 72,000 public companies in 130 countries and provides a classification history going back to 1999.
The sectors are broadly the same as other systems such as ICB, except for the addition of Institutions, Associations & Organizations; Government Activity and Academic & Educational Services.
