How this list is ranked
Companies are ranked by annual revenue (USD) as recorded on each company's profile in the Factur directory, highest first; companies with the same revenue are ordered by employee count. Only companies with a positive revenue figure on file are ranked, so a large private company with no reported revenue can be missing. The list covers companies whose record places them in Connecticut and whose Factur industry is Financial. Figures are a snapshot of the directory, refreshed when the rankings are regenerated; open a profile for its current data.
