The Dun & Bradstreet rating is a powerful indicator of a firm's size and composite credit appraisal that can help you assess credit risk. It's a reliable and easy-to-interpret business tool that measures overall credit worthiness on a scale of 1 to 4, based on key credit information in Dun & Bradstreet's file such as payment activity, financial condition, years in business and public filings. The size of a company can also give you valuable insight on its credit capacity. You can turn to the Dun & Bradstreet ratings in the Reference Book of American Business to help with more of your business decisions. The extensive range of financial and other business information contained in our books is what makes the D&B rating such a powerful risk-management tool .
