Thomson Reuters Business Classification Methodology
Updated January 2012

SECTOR REVIEW

Thomson Reuters Business Classification schema is reviewed every year. Company assignments are reviewed quarterly when earnings are filed.

Since its introduction in 2004 the TRBC steering group, consisting of internal Thomson Reuters and external business stakeholders has met regularly to review the structure of the scheme. The 2008 review produced recommendations to revise the scheme, with revisions effective from August 2009. The steering group meets on a quarterly basis to review emerging issues and solicit feedback from the investment community.

Every company in the TRBC universe is reviewed at least annually to determine if the assignment remains valid or whether the company has changed business model and/or business segments have changed in importance either organically or through acquisition/divestment. Over 50,000 companies are therefore reviewed every year by our dedicated content operations. Our analysts review the detailed financials of each business segment, update company descriptions and review any corporate activity that may have impacted company operations. We have a sophisticated alerting mechanism for corporate actions using various Thomson Reuters databases to ensure that all activity that could impact industry assignment is considered. Please see our methodology document for more details.

Test Driving Industry Classifications
Geoff Horrell & Rich Meraz
Sept./Oct. 2009 Issue

This paper describes how industry classifications in general, and Thomson Reuters Business Classification (TRBC) in particular, drive many aspects of modern investment management. They explore the idea that for an industry grouping to be useful, its constituents should have a tighter correlation to each other than each has to the overall market.
