Dun & Bradstreet is a U.S.-based business that collects and analyzes financial information about companies around the world. The data collected is used by D&B customers to determine creditworthiness, devise marketing schemes and perform risk assessment, according to Dun & Bradstreet's official website.
Among legal researchers, the most popular reports D&B produces are the Business Information Reports on individual companies and the Family Linkages Reports on corporate affiliations, according to LexisNexis. A BIR includes the company's debt rating, its liabilities and payment history, officers, major shareholders and other information that may not be readily available elsewhere. These reports are available to be purchased, though they are not produced for all existing companies.
